Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board patch clamps, in particular to a flexible circuit board patch clamp. Background Art

[0002] Flexible Printed Circuit (FPC) is a printed circuit board made of polyimide or polyester film as a substrate with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness and good bendability.

[0003] During the production process of flexible circuit boards, components need to be mounted at corresponding positions on the flexible circuit boards according to customer needs. However, since the FPC boards are not hard enough and are relatively soft, if special patch fixtures are not used, they cannot be fixed and transferred, and basic SMT processes such as printing, patching, and furnace passing cannot be completed.

[0004] When the existing patch fixture is clamped and fixed, if the clamping block on the fixture and the patch area are large, the patch position is easily blocked, resulting in the inability to mount the patch at that position. If the clamping block and the patch area are small, it is easy to cause deviation, affecting the mounting quality. Utility Model Content

[0007] Preferably, a base is clamped at the bottom of the placement plate, and an installation cavity for installing the adsorption component is provided inside the base.

[0008] Preferably, the through holes are equidistantly located between the plurality of guide grooves, and connecting pipes are fixedly provided at the bottom of the guide grooves.

[0009] Preferably, the adsorption assembly includes a vacuum pump fixedly mounted on the bottom of the inner wall of the installation cavity, and a fixed pipe for connecting multiple connecting pipes is fixedly mounted on the output end of the vacuum pump, and the multiple connecting pipes are all connected to the fixed pipe.

[0010] Preferably, the guide groove includes two through grooves arranged in parallel.

[0011] Preferably, the clamping mechanism includes a slider slidably arranged in two through grooves, the slider passes through the bottom of the through groove and is fixed with a fixing piece at one end, a displacement groove is provided inside the slider, a clamp block is slidably arranged in the displacement groove, a connecting rod is provided on the top of the clamp block, a handle is fixedly arranged on one end of the connecting rod that movably passes through the top of the slider, and a spring for clamping the clamp block is fixedly provided between the top of the clamp block and the inner wall of the displacement groove.

[0012] Preferably, a rubber pad for contacting the patch is fixedly provided at the bottom of the clamping block.

[0013] The beneficial effects of the utility model are as follows:

[0014] Compared with the prior art, the device limits the patch by adsorption and edge pressing, which is simple to operate, precise in limiting and highly stable, and avoids the situation where the clamping block on the fixture and the patch area are large, which easily blocks the position of the patch. At the same time, the clamping mechanism cooperates with the top surface of the placement plate to limit patches of different thicknesses.

[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0020] Example 1

[0021] See also Figure 1-4 The present embodiment provides a flexible circuit board patch fixture including a placement plate 110, on which a plurality of guide grooves 120 are arranged divergently along the intersection of the diagonals of the placement plate 110, and inside the guide grooves 120, a clamping mechanism 140 for limiting the position of the patch is slidably arranged; the placement plate 110 is provided with a plurality of through holes 130, and at the bottom of the plurality of through holes 130, an adsorption component for adsorbing the patch is provided.

[0022] The number of the guide grooves 120 is at least four.

[0023] When the present embodiment is in use, the patch is placed on the top of the placement plate 110, and the vacuum pump 240 is started. The vacuum pump 240 creates negative pressure in the fixed tube 230 and the connecting tube 220, and adsorbs the patch through the through hole 130. The clamping mechanism 140 is then moved to the edge of the patch, and the handle 350 is pulled to pull the clamping block 320 away from the surface of the placement plate 110. The clamping mechanism 140 is moved to press the clamping block 320 against the edge of the patch for position limiting. Compared with the prior art, the present device limits the patch by adsorption and edge pressing, and is simple to operate, precise in positioning, and highly stable, and avoids the situation where the clamping block on the fixture and the patch area are large, which easily blocks the position of the patch.

[0024] In this embodiment, a base 100 is clamped at the bottom of the placement plate 110 , and an installation cavity 210 for installing the adsorption component is provided inside the base 100 .

[0025] The above structure can not only support the bottom of the placement plate 110, but also protect the adsorption component.

[0026] In this embodiment, the through holes 130 are equidistantly located between the plurality of guide grooves 120 , and a connecting pipe 220 is fixedly disposed at the bottom of each guide groove 120 .

[0027] Through the above structure, the bottom of the patch can be evenly adsorbed to improve the adsorption effect.

[0028] In this embodiment, the adsorption assembly includes a vacuum pump 240 fixed at the bottom of the inner wall of the installation cavity 210, and a fixed pipe 230 for connecting multiple connecting pipes 220 is fixed at the output end of the vacuum pump 240, and the multiple connecting pipes 220 are all connected to the fixed pipe 230.

[0029] Through the above structure, the patch can be uniformly adsorbed, avoiding the situation where the clamping block on the clamp and the patch have a large area, which easily blocks the position of the patch.

[0030] In this embodiment, the guide groove 120 includes two parallel through grooves.

[0031] Through the above structure, the clamping mechanism 140 can slide along the guide groove 120 more stably.

[0032] In this embodiment, the clamping mechanism 140 includes a slider 310 that is slidably arranged in two through grooves. The slider 310 passes through the bottom of the through groove and is fixed with a fixing part 410 at one end. A displacement groove is arranged inside the slider 310. A clamping block 320 is slidably arranged in the displacement groove. A connecting rod 330 is arranged on the top of the clamping block 320. The connecting rod 330 movably passes through the top of the slider 310 and is fixed with a handle 350 at one end. A spring 340 for clamping the clamping block 320 is fixed between the top of the clamping block 320 and the inner wall of the displacement groove.

[0033] Through the above structure, the user pulls the handle 350, and the handle 350 drives the connecting rod 330 and the clamping block 320 on the connecting rod 330 to rise. At the same time, the top surface of the placement plate 110 can be used to limit the patches of different thicknesses. The operation is simple and the installation is fast. The edges of patches of different sizes can be limited to improve the stability of the patches.

[0034] In this embodiment, a rubber pad 420 for contacting the patch is fixedly provided at the bottom of the clamping block 320 .

[0035] The above structure can prevent the bottom of the clamping block 320 from directly contacting the patch to cause indentation and damage the patch.

[0036] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0037] The above is a schematic description of the present invention and its implementation methods, which is not restrictive. The embodiments shown are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the present invention, they should all fall within the protection scope of the present invention.
