When an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] As Figs. 1-2As shown, a flexible FPC board back adhesive attaching tool, including a base 1, a carrier 2, a cover plate 3 and a pressure joint 4, the carrier 2 is installed on the base 1, two groups of pressure joints 4 are installed on the edge of the base 1, the edge of the cover plate 3 is hinged with the edge of the carrier 2, one side of the cover plate 3 facing the carrier 2 is provided with a pressing part 31, the upper end surface of the carrier 2 is provided with a groove 21 for placing the FPC board 100, the pressing part 31 and the groove 21 are matched, and the pressing part 31 and the groove 21 are integrated with vacuum suction holes 5, and the output end of the pressure joint 4 is movably connected with the side of the cover plate 3 away from the carrier 2. Specifically, in this embodiment, when in use, we place the FPC board 100 in the groove 21, because the groove 21 is integrated with a plurality of vacuum suction holes 5, the plurality of vacuum suction holes 5 are in communication with the negative pressure equipment pipeline outside through the air path in the carrier 2, thereby firmly adsorbing the FPC board 100 in the groove 21, avoiding displacement during the gluing process, when the gluing is completed, the film (not shown in the figure) to be laminated is attached to the pressing part 31 of the cover plate 3, which is also attached by the negative pressure equipment, to avoid the film falling down during the attaching process. When laminating, the operator only needs to manually turn over the cover plate 3, so that the pressing part 31 is embedded in the groove 21, at this time, the film can be attached to the FPC board 100. In order to maintain the pressure, we set pressure joints 4 on both sides of the base 1, which provide pressure for the cover plate 3, so that it can be attached to the carrier 2 for a long time, ensuring that the film can be firmly attached to the FPC board 100, tightly attached, ensuring the bonding precision, improving the reliability and overall performance of the product, and reducing the operation difficulty.

[0016] As shown in the figure, Figs. 1-2 The edge of the groove 21 is provided with an exhaust groove 22, specifically, the exhaust groove 22 is used to exhaust the gas in the sealing space when the pressing part 31 is matched with the groove 21, to avoid the puffing sound when pressing, and to make the cover plate 3 more smooth when turning over and pressing on the carrier 2, and to avoid the cover plate 3 not being completely flat due to the gas in the sealing space formed by the pressing part 31 and the groove 21.

[0017] As shown in the figure, Figs. 1-2 The groove 21 is also provided with a plurality of first spring positioning pins 23 for positioning the FPC board 100, which are used for positioning to prevent the FPC board 100 from being placed in wrong position and improve the placement accuracy.

[0018] As shown in the figure, Fig. 1As shown, the upper end face edge of the carrier 2 is further provided with a second spring positioning pin 24 for positioning the cover plate 3, and the cover plate 3 is provided with a insertion hole 32 corresponding to the second spring positioning pin 24. Specifically, the cover plate 3 is hinged with the carrier 2 through a hinge, and the hinge may be loose after being used for a long time, so that the pressing part 31 is misaligned with the groove 21 when the cover plate 3 is covered on the carrier 2. In order to avoid misalignment, the second spring positioning pin 24 and the insertion hole 32 are matched to play a guiding role.

[0019] As shown, Figs. 1-2 Further, a buffer seat 6 is further included, which includes a spring 61, a supporting plate 62, a guide column 63 and a pad sleeve 64. The upper end of the guide column 63 is movably connected with the carrier 2, and the lower end movably penetrates through the supporting plate 62 and is connected with the base 1. The pad sleeve 64 is sleeved on the guide column 63 and used for supporting the supporting plate 62. The upper end of the pad sleeve 64 movably abuts against the lower end of the carrier 2. The spring 61 is vertically arranged between the supporting plate 62 and the base 1. Specifically, the upper end of the guide column 63 is movably inserted into the lower end of the carrier 2, so that the carrier 2 can be conveniently taken down for maintenance or replaced according to the FPC board 100 of different models. When the pressure applying piece 4 applies pressure on the cover plate 3, the pressure is conducted to the upper end of the pad sleeve 64 through the carrier 2. Since the pad sleeve 64 is movably sleeved on the guide column 63 and the pad sleeve 64 is connected with the supporting plate 62, the pressure is conducted to the supporting plate 62 through the pad sleeve 64. The supporting plate 62 is guided through the guide column 63. When the supporting plate 62 is under pressure, it slides downward along the guide column 63. At this time, the spring 61 between the supporting plate 62 and the base 1 is compressed, thereby completing the buffering. The supporting plate 62 can uniformly disperse the pressure to the springs 61, so that the single spring 61 is not unevenly stressed.

[0020] The above-described embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
