Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to an FPC flexible board crimping jig. Background Art

[0002] An FPC flexible board crimping jig is a device that connects an FPC flexible circuit board to other components or circuit boards by applying pressure. However, during the crimping process, the FPC flexible circuit board is made of soft material and some edges may have warping or uneven board surfaces. This often leads to uneven crimping results, affecting the reliability and stability of the connection. To this end, we propose an FPC flexible board crimping jig. Utility Model Content

[0003] (1) Technical problems solved

[0004] In view of the deficiencies in the prior art, the present invention provides an FPC flexible board crimping jig to solve the above-mentioned problems in the prior art.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an FPC flexible board crimping jig, comprising a body, a carrying plate for carrying materials, and a cylinder located on the top of the body, the bottom output end of the cylinder is connected to a crimping plate, and extension plates are symmetrically provided on the two rear edges of the crimping plate, a rotating shaft is rotatably connected to the two extension plates, the rotating shaft passes through the two extension plates and extends to both sides, and its two ends are respectively connected to rotating arms, a flattening roller for flattening the material is rotatably connected between the two rotating arms, the outer wall of the rotating shaft is sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the outer wall of the rotating shaft and the corresponding extension plate, so that when no external force is applied, the angle between the rotating arm and the crimping plate is an acute angle.

[0007] Furthermore, a step plate is provided at the top of the front end of the pressing plate, and the bottom of the step plate is connected to a pressing plate via a supporting spring to cooperate with the top of the squeezing flattening roller.

[0008] Furthermore, a rotatable positioning block is provided on the top of the rear end of the supporting plate. The positioning block is a cam structure, and a wrench plate is provided on one side of the positioning block to move the positioning block so that it can squeeze and position the material on the top of the supporting plate.

[0012] (3) Beneficial effects

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] Refer to the attached Figure 1-5 An FPC flexible board crimping jig includes a body 1 as the support structure of the entire jig, a carrier plate 2 for carrying the material to be crimped, and a cylinder 3 located on the top of the body 1 as the power source for crimping. The bottom output end of the cylinder 3 is connected to a crimping plate 4. When the cylinder 3 is started, the crimping plate 4 moves downward to crimp the material on the carrier plate 2;

[0024] The two ends of the torsion spring 43 are fixedly connected to the outer wall of the rotating shaft 42 and the corresponding extension plate 41, so that when no external force is applied, the angle between the rotating arm 44 and the crimping plate 4 is an acute angle. During crimping, the crimping plate 4 drives the flattening roller 45 to move downward. When the flattening roller 45 squeezes the material on the supporting plate 2, it will be subjected to a reaction force, causing the rotating arm 44 and the rotating shaft 42 to rotate, further causing the flattening roller 45 to slide forward along the top of the supporting plate 2, thereby flattening the material on the supporting plate 2 to avoid wrinkles in the material during crimping that affect the quality of the product.

[0025] In this embodiment, a step plate 46 is provided at the top of the front end of the crimping plate 4, and the bottom of the step plate 46 is connected to a pressure plate 48 through a support spring 47 to cooperate with the top of the squeezing flattening roller 45. When the flattening roller 45 slides to the front of the crimping plate 4, the flattening roller 45 just moves to the bottom of the pressure plate 48. At this time, under the support of the support spring 47, the pressure plate 48 squeezes the flattening roller 45, so that the flattening roller 45 always has a certain pressure on the material to avoid elastic shrinkage of the material and affect the crimping quality.

[0026] In this embodiment, a rotatable positioning block 21 is provided at the top of the rear end of the supporting plate 2. The positioning block 21 is a cam structure, and a wrench plate 22 is provided on one side thereof to pull the positioning block 21 so that it can squeeze and position the material on the top of the supporting plate 2. Before the flattening operation, the wrench plate 22 is pulled. At this time, the positioning block 21 rotates, and the most protruding point of its cam structure squeezes the top of one side of the material, so that one side of the material is fixed to the supporting plate 2, which is convenient for quickly fixing one side of the material and facilitating subsequent flattening work.

[0027] In this embodiment, guide columns 24 are symmetrically provided on the supporting plate 2, and the outer walls of the guide columns 24 are slidably connected to the limiting plates 25. The two sides of the limiting plates 25 are connected to the top of the supporting plate 2 through connecting springs 26. The bottom of the limiting plate 25 abuts against the outer wall of the positioning block 21. The positioning block 21 is provided with a limiting groove 23 that cooperates with the limiting plate 25. When the positioning block 21 rotates, the bottom of the limiting plate 25 will slide into the limiting groove 23, which can realize the limitation of the positioning block 21 and ensure that it will not shake during the crimping process.

[0028] In this embodiment, the two sides of the bottom of the limit plate 25 are arc-shaped structures to cooperate with the rotation of the positioning block 21, and the two sides inside the limit groove 23 are vertical surfaces to stably accommodate the limit plate 25, so as to ensure that when the limit plate 25 is inserted into the limit groove 23, the pulling force of the flattening roller 45 on the material will not cause the material to move, so as to ensure the stability and accuracy of the positioning.

[0029] In this embodiment, a handle 27 is provided on the top of the limiting plate 25. By pulling the handle 27 upward, the limiting plate 25 can be quickly lifted, so that the limiting plate 25 is separated from the limiting groove 23, thereby facilitating the resetting of the positioning block 21 to release the squeezing of the material.
