Figure 1-5 shows devices that implement the proposed method.

The device contains a surface for transporting products, over which there is a node for supplying products, a node for wetting the transfer elements, a node for forming lowercase sequences and a set of transfer elements for FIGS. 1 and 2 of products of a lowercase sequence for fixing them on a common carrier 1, which are made with a flat elastic plate 2, a film closed surface 3 is introduced, along the edges of which are rectangular grooves 4, the width of which is not less than the width of the flat elastic plate 2 of the transfer element 5, while the distance between the same grooves 4 on the film closed surface 3 is equal to the distance between the rectangular bends 6, which are made on the edges of the elastic plate 2 of the transfer element and which are located in the rectangular holes of the same name 4, the film closed surface 3, between which in the middle part of the closed film surface are made larger rectangular holes 7 for controlling transfer elements 5, while a closed film surface 3 with transfer elements 5 is located on two pairs of disks 8 and 9 with p Zami interconnected common axes 11 and 12.

In this case, each of the transfer elements 5 is molded in the form of a rectangular plate 13, on the one hand of which a wetted surface 14 of suede-treated leather is fixed, on the other hand, a stiffener 15 is placed in one piece, which is placed along the rectangular plate 13, while the Central part of the ribs 15 in one piece perform one or two flat elastic plates 2 with rectangular bends 6 on the edge, which are located on the edges of the ribs 15 with fixation in its central part, while the plane Springsteen has a coplanar rectangular plate 13.

The operation of the proposed device is as follows.

Products are fed to the transportation surface and in the reception zone, lower-case sequences of products are formed for subsequent transfer to a common carrier with a moistened surface 14 as a sequential set of transfer elements 5 with a flat elastic plate 2, which can be displaced continuously or discretely, with each of the transfer elements 5 perform with the possibility of parallel and vertical displacement of figure 4 for receiving products and installing or fixing them in the corresponding positional positions on a common carrier 1, which is located under the transfer elements of figures 1 and 3-5.

The set of transfer elements 5 is made in the form of a linear closed sequence of figure 2, while the flat elastic plates 2 of the transfer elements 5 are made with rectangular bends 6 on the edge on both sides and are arranged in a sequence of rectangular holes 4 of the closed film surface 3 on its inner side and are positioned closed film surface 3 on axes 11 offset from each other with gear disks 8 and 9, which are fixed along the edges of axes 11 and 12, while the pitch of the grooves 10 in the gear disks 8 and 9 are chosen equal m step arrangement of rectangular bends 6 flat elastic plates 2.

The reception of products on the wetted surface 14 of the transfer element 5 is similar to the installation of products of a lower order sequence on a common carrier 1. Figure 3 shows a set of transfer elements 5 before installing the products on a common carrier 1, figure 4 shows a set of transfer elements 5 during installation of products on a common carrier 1, and Fig. 5 shows a set of transfer elements 5 after installing the products on a common carrier 1. To install the products on a common carrier 1, just click on the transfer element through a rectangular hole 7 5, and it is lowered by the wetted surface 14 onto the formed set of elements of the horizontal sequence, and due to the surface tension of the liquid, such as water, they adhere to the wetted surface 14 of the transfer element 5. In this case, the rectangular bend 6 and the rectangular holes 4 in the closed surface 3 allow you to adjust transfer element when it returns to its original position.

Installing or fixing the products on a common carrier includes lowering the transfer member 5 onto the common carrier 1, on which solder paste or glue droplets are pre-applied at the locations of the products, and the products are essentially glued from the transfer member 5 to the common carrier 1 because viscosity or surface forces solder paste or glue above similar water forces.

The use of the invention improves the reliability of small-sized surface-mount automatic machines by using a film closed surface in which corrective rectangular grooves are made, and also provides parallel displacement of the entire set of transfer elements.
