The prior art usually uses a PI (polyimide) tape to paste and fix the product and the traction plate. Since the traction plate is pasted together with the FPC product edge by the PI tape, the high temperature, acid and alkali chemical corrosion and easy aging of the tape may cause residue of foreign matter at the connection between the product and the tape, surface contamination of the product, incomplete drying of the product, poor quality of the FPC product, and even scrapping of the product, thereby increasing the production cost.

[0005] The traction plate for FPC horizontal line production has the clamping grooves formed by the clamping feet with the elastic transition belt and the gaps alternately lifted and pressed, which can clamp the FPC, thereby solving the problems of surface contamination, incomplete cleaning, incomplete drying of the product edge, poor quality of the FPC product, and even scrapping of the product, thereby improving the quality of the FPC product, reducing the scrapping, and lowering the production cost. In addition, the clamping grooves formed by the clamping feet alternately lifted and pressed can better clamp the FPC. Furthermore, the elastic transition belt arranged between the clamping feet and the traction plate body can form a hinged effect at the connection between the clamping feet and the traction plate body, thereby increasing the service life of the clamping feet alternately lifted and pressed to clamp the FPC.

[0016] Figure 2 It is a schematic view of the traction plate clamping FPC used in the utility model FPC horizontal line production. DETAILED DESCRIPTION
[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0018] In the utility model, it needs to be explained that if the embodiment of the utility model involves directionality indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, …), then the directionality indication is only used to explain the relative position relationship, movement condition and the like between components in a certain specific posture (as shown in the drawings), if the specific posture changes, then the directionality indication also changes accordingly.
[0019] A traction plate for FPC horizontal line production uses, as shown in Figure 1 and Figure 2 , including traction plate body 1, a row of clamping feet 2 is protruded on one side of the traction plate body, elastic transition belt 3 is arranged between the clamping feet and the traction plate body, gap 4 is arranged between the clamping feet, the clamping feet with elastic transition belt and gap are alternately lifted and pressed to form clamping grooves for clamping FPC 5 between the clamping feet.
[0020] By protruding a row of clamping feet on one side of the traction plate body, the clamping grooves formed by alternately lifting and pressing between the clamping feet with elastic transition belt and gap clamp FPC, thereby solving the problem of surface pollution, incomplete cleaning, easy to make the board edge drying incomplete, leading to poor quality of FPC product even existence of scrap to increase production cost caused by PI tape in the production process, thereby improving the quality of FPC product, reducing scrap and reducing production cost; in addition, since the clamping grooves are formed by alternately lifting and pressing between the clamping feet, the clamping effect on FPC is better; in addition, since the elastic transition belt is arranged between the clamping feet and the traction plate body, the connection between the clamping feet and the traction plate body can form a hinged effect, thereby increasing the service life of the clamping feet for alternately lifting and pressing FPC.
[0021] The elastic transition belt includes a spring piece, one side of the spring piece is fixedly connected with the traction plate body, the other side is fixedly connected with the clamping foot, by means of the spring piece, the clamping feet and the traction plate body can have elastic effect, and the clamping of FPC is more firm; in addition, the spring piece is provided as a thin spring piece, so that the traction plate is made thinner and occupies smaller space; in addition, the elastic transition belt further includes woven cloth wrapped outside the spring piece, which can better protect the spring piece and the connection between the traction plate body and the spring piece and the clamping foot and the spring piece.
[0022] The material of the traction plate body and the clamping leg is plastic material, the traction plate body and the clamping leg of plastic material are fixedly connected with the elastic sheet through hot melting welding. The traction plate body and the clamping leg of plastic material are lighter in weight, and are more convenient for clamping the FPC; in addition, the clamping leg is a rectangular clamping leg, the surface of the rectangular clamping leg is easier to be attached to the FPC, and is more convenient for clamping; in addition, the clamping leg is an elastic clamping leg, the elastic clamping leg is also more convenient for lifting and pressing down, and is not easy to be broken, thereby prolonging the overall service life of the traction plate.
[0023] The width size of the gap between the clamping legs / the width size of the lifting clamping leg is equal to 1:2, the width size of the gap is half of the width size of the lifting clamping leg, the distance between the clamping legs can be prevented from being too small or too large, thereby affecting the lifting and pressing down of the clamping legs in turn.
[0024] The above embodiments are only used to illustrate the detailed scheme of the traction plate, and the traction plate is not limited to the above detailed scheme, that is, it does not mean that the traction plate must rely on the above detailed scheme to be implemented. It should be understood by those skilled in the art that any improvement on the traction plate, equivalent replacement of raw materials of the traction plate product, addition of auxiliary ingredients, selection of specific modes and the like fall within the protection scope and disclosure scope of the traction plate.
