Description

Thin-type optical tool carrier and its application operating equipment

The present invention provides a thin optical tool carrier capable of radially arranging light transmission elements for illumination and preventing high temperature during illumination operation, thereby improving the use efficiency.

Nowadays, when the electronic component working equipment performs the combined assembly operation of a plurality of different electronic components (such as chips and flexible circuit boards), different devices (such as working devices and conveying devices) are used to transfer different electronic components to be operated; For example, the hot-pressing cooperative industry equipment uses the hot-pressing device of the hot-pressing device to transfer the chip, and the transfer device of the conveying device to transfer the flexible circuit board. Since the chip has multiple pins, the flexible circuit board has multiple In order to make the pins of the chip accurately connect to the electrical contacts of the flexible circuit board, the hot-press cooperation equipment is equipped with an imaging device to capture the electrical contacts of the flexible circuit board for central control The device controls the thermal press to adjust and calibrate the placement of the chip, so that the pins of the chip and the electrical contacts of the flexible circuit board are accurately aligned and pressed.

Of course, the imaging device is to enable the imaging device (such as CCD) to clearly capture the flexible circuit board, that is, a illuminator is installed on the imaging device to assist lighting. The illuminator includes a light source base and a plurality of LED light sources. The light source base is assembled In the viewfinder, a through hole is opened for the viewfinder to take the flexible circuit board through the through hole. A plurality of LED light sources are arranged vertically and placed on the inner surface of the through hole of the light source base to fit inside the through hole. Light and illuminate the flexible circuit board to facilitate the image capture of the flexible circuit board.

However, because the LED light source of the illuminator is a light source, it will generate high temperature when it emits light. When multiple high-temperature LED light sources directly transmit the high temperature to the light source base, the light source base will be damaged due to the high temperature. In addition, when the imaging device crashes during the imaging process, and the high-temperature light source base is parked on the flexible circuit board, the flexible circuit board is a soft thin plastic sheet, and both the light source base and the LED light source have high temperature. In the case of, the flexible circuit board is susceptible to the high temperature of the light source base and the LED light source, which not only causes the problem of deformation and damage of the flexible circuit board, but also affects the alignment accuracy of the electrical contacts of the flexible circuit board and the pins of the chip. Hot pressing quality.

Furthermore, because the LED light source is limited to its side-lighting requirements, it must be arranged upright on the inner surface of the through hole of the light source base, which not only increases the height of the light source base, but also when the taller light source base is mounted on the imager , It also increases the height of the entire set of image capturing devices. When the image capturing device is used between the thermocompression device and the material shifter to perform image capturing operations, the industry must raise the heat pressure in order to make the thermocompression device avoid the image capturing device. The assembly position of the combiner, in other words, this will increase the heat-pressing displacement path of the heat-compressor, but a heat-compressor with an excessively high position will not only increase the displacement time and reduce the working efficiency, but also cause unstable heat-pressing operation effects. The problem.

Furthermore, the use efficiency of the optical bench is improved.

The second objective of the present invention is to provide a thin optical tool carrier for radially assembling light transmission components, so that the optical tool carrier can maintain a preset temperature under the condition that the light transmission components do not generate high temperature. When the optical bench is parked above the object to be taken due to the acquisition timing or abnormal timing, the object to be acquired can be prevented from being damaged, and the practical benefits of ensuring the quality of the object and the accuracy of the operation of the object can be achieved.
