Description

Technical Field

[0001] The present application relates to the technical field of electronic product processing, and particularly relates to a clamping tooling and a bending device. Background Art

[0002] A flexible printed circuit (FPC) is a printed circuit board made of polyimide or polyester film as a substrate, which has high reliability and excellent flexibility. Due to its advantages such as high wiring density, light weight, and thin thickness, it is widely used in the electronics industry. Currently, the FPC is one of the important components of the signal transmission function module inside the battery. During the battery packaging process, generally, the FPC needs to be bent and then mounted on the battery cell, and then the entire battery cell is placed in an injection mold for in-mold injection molding, so as to cover an insulating protective shell on the surface of the battery cell.

[0003] In the related art, generally, an FPC bending jig is used to fix and bend the FPC. However, in the traditional FPC bending jig, generally, an operator needs to fix the wire arrangement step by step and manually complete the flipping and bending actions. Since it cannot fix both ends of the FPC wire arrangement with special shape at the same time, it is easy to cause partial wire arrangement of the FPC to shift. Summary of the Invention

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the scope of protection of the present application.

[0035] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0036] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms such as "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or movement state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will then be oriented as "above" or "over" other elements or features. Therefore, the exemplary term "below" may include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0037] See Figures 1 to 8, an embodiment of the present application provides a clamping tooling, which includes: a base 100 having a first installation groove for placing a special-shaped end of a workpiece to be processed; a first clamping assembly 200 movably arranged on the base 100 and located at the starting end of the first installation groove; a second clamping assembly 300 movably arranged on the base 100 and located at the tail end of the first installation groove; and a first transmission assembly 400 movably arranged on the base 100 and simultaneously drivingly connected to the first clamping assembly 200 and the second clamping assembly 300 to drive the first clamping assembly 200 and the second clamping assembly 300 to clamp or open simultaneously.

[0038] In this embodiment, the starting end of the special-shaped end is clamped and fixed by the first clamping assembly 200. At the same time, the tail end of the special-shaped end is clamped and fixed by the second clamping assembly 300, which increases the number of clamping points between the clamping tooling 20 and the special-shaped end, improves the clamping stability and reliability of the clamping tooling 20 for the special-shaped end, and has a good clamping effect. Moreover, a first transmission assembly 400 that is simultaneously drivingly connected to the first clamping assembly 200 and the second clamping assembly 300 is added. It is intended to achieve the synchronous operation of the first clamping assembly 200 and the second clamping assembly 300 through the first transmission assembly 400, so that the two can simultaneously clamp or release the head and tail ends of the special-shaped end on the workpiece to be processed, preventing the situation where the partial wiring of the FPC is prone to shift when the head and tail ends of the special-shaped end are clamped one by one, greatly improving the clamping and fixing accuracy and clamping effect of the FPC at least on its special-shaped end, and improving the yield of the FPC formed product.

[0039] Specifically, the clamping tooling 20 is configured to be a combined component including at least a base 100, a first clamping component 200, a second clamping component 300, and a first transmission component 400. The base 100 can be an integral structure or a split structure. A first installation groove is provided at the top thereof, and the first installation groove is of a special shape for accommodating the special-shaped end of the workpiece to be processed. The first clamping component 200 can be a jaw structure that opens or closes along the third direction P of the base 100. It is arranged at the head end of the first installation groove and can form a part of the first installation groove. The second clamping component 300 can be a jaw structure that opens or closes along the second direction Y of the base 100. It is arranged at the tail end of the first installation groove. Among them, the straight line where the second direction Y is located and the straight line where the third direction P is located are arranged at an angle. In this way, the first clamping component 200 and the second clamping component 300 can be used to simultaneously clamp different positions of the special-shaped end of the workpiece to be processed, and the clamping tooling 20 can accurately clamp the special-shaped end. The first transmission component 400 can be a three-section link mechanism, at least including an operation part, a first transmission part linked to the first clamping component 200, and a second transmission part linked to the second clamping component 300. In this way, the operator can drive the first transmission part to move through the operation part, and drive the first clamping component 200 connected to the first transmission part to move synchronously. At the same time, the first transmission part drives the second transmission part to move, and drives the second clamping component 300 connected to the second transmission part to move synchronously, so as to realize the synchronous clamping or synchronous opening of the first clamping component 200 and the second clamping component 300, realize the simultaneous clamping or simultaneous loosening of different positions of the special-shaped end of the workpiece to be processed, and have high clamping accuracy and good clamping effect on the workpiece to be processed.

[0040] In a possible implementation manner, as Figures 1 to 4 shown, the first transmission component 400 includes an operating member 410, a first transmission member 420 movably connected to the operating member 410, and a second transmission member 430 movably connected to one end of the first transmission member 420 away from the operating member 410. The operating member 410 exposes the base 100, and both the first transmission member 420 and the second transmission member 430 are accommodated in the base 100. The first clamping component 200 is movably connected to the first transmission member 420, and the second clamping component 300 is movably connected to the second transmission member 430.

[0041] In this embodiment, the specific configuration of the first transmission assembly 400 is optimized. Specifically, the first transmission assembly 400 is configured as a combined component including at least an operating member 410, a first transmission member 420, and a second transmission member 430. The operating member 410 can be an operating handle, the inner end of which is connected to the first transmission member 420 and can partially extend into the base 100 along with the first transmission member 420; the outer end is exposed from the base 100 and can be sleeved with a soft rubber sleeve for convenient grasping by the operator. The first transmission member 420 can be a long plate-shaped / long block-shaped structure similar to a near-knife shape, which extends along the first direction X of the base 100 and covers the first clamping assembly 200 in this direction; the first transmission member 420 can drive the first clamping assembly 200 to reciprocate in the first direction X, so as to realize the clamping or opening of the first clamping assembly 200 in the P direction. The second transmission member 430 can be a long slide plate / long slider, which extends along the second direction Y of the base 100 and can drive the second clamping assembly 300 to reciprocate in the second direction Y, so as to realize the clamping or opening of the second clamping assembly 300 in the Y direction. One end of the first transmission member 420 is movably connected to the operating member 410, and the other end is drivingly connected to the second transmission member 430, so that when the operating member 410 is moved, the first transmission member 420 and the second transmission member 430 can be driven to move synchronously, thereby realizing the simultaneous clamping or opening of the first clamping assembly 200 and the second clamping assembly 300, and realizing the clamping and fixing of different positions of the special-shaped end. The first transmission assembly 400 provided in this example has at least two states, namely the first state and the second state. In the first state, the operating member 410 is closed, and the first transmission member 420 and the second transmission member 430 are in the first position. At this time, the first clamping assembly 200 and the second clamping assembly 300 are in the open state; in the second state, the operating member 410 is opened, and the first transmission member 420 and the second transmission member 430 are in the second position. At this time, the first transmission member 420 is pulled by the operating member 410, and the second transmission member 430 is pulled by the first transmission member 420, so that both the first clamping assembly 200 and the second clamping assembly 300 are in the clamped state.

[0042] In a possible implementation manner, as Figure 4 shown, the operating member 410 is rotatably connected to the first transmission member 420, and the first transmission member 420 is movably connected to the second transmission member 430 through a first limiting waist hole 401. Rotating the operating member 410 around the straight line in the thickness direction Z of the base 100 drives the first transmission member 420 to move along the first direction X of the base 100, and at the same time drives the second transmission member 430 to move along the second direction Y of the base 100 under the force constraint of the first limiting waist hole 401, wherein the straight line where the first direction X is located and the straight line where the second direction Y is located are arranged at an angle.

[0043] In this embodiment, the connection manner between the components of the first transmission assembly 400 is optimized. Specifically, an operating member 410 can be rotatably connected to one end of a first transmission member 420 through a hinge seat or a rotating shaft. At the same time, an inclined first limiting waist-shaped hole 401 is formed at the other end of the first transmission member 420, and a connecting post is arranged on the second transmission member 430. The connecting post can be inserted into the first limiting waist-shaped hole 401 to realize the follow-up connection between the first transmission member 420 and the second transmission member 430. In this way, by rotating the operating member 410, the synchronous linear movement of the two transmission members in the first direction X and the second direction Y can be realized, so as to realize the synchronous clamping or opening of the two clamping assemblies in the third direction P and the second direction Y respectively, and realize the simultaneous clamping and fixing or loosening of different positions of the special-shaped end of the workpiece to be processed, improving the clamping accuracy and clamping and fixing effect of the clamping tooling 20 on the workpiece to be processed. For example, by driving the operating member 410 to rotate around the straight line in the thickness direction Z of the base 100, the first transmission member 420 can be driven to move linearly along the first direction X, and at the same time, the second transmission member 430 can be driven to move linearly along the second direction Y. At this time, the first clamping assembly 200 connected to the first transmission member 420 moves accordingly and realizes its clamping or opening in the third direction P, and the second clamping assembly 300 connected to the second transmission member 430 moves accordingly and realizes its clamping or opening in the second direction Y, so as to realize the simultaneous clamping and fixing or loosening of the special-shaped end of the workpiece to be processed by the clamping tooling 20 in the third direction P and the second direction Y, with good fixing effect and high yield rate. The first transmission assembly 400 provided in this example has a three-section structure, and at least includes an arc track and two straight tracks during transmission, and can realize the simultaneous clamping or loosening of the special-shaped end of the workpiece to be processed in at least two directions, with good clamping and fixing effect.

[0044] In one example, the straight line where the first direction X is located is perpendicular to the straight line where the second direction Y is located, and the straight line where the third direction P is located forms an angle with both the straight line where the first direction X is located and the straight line where the second direction Y is located. That is to say, the straight line where the first direction X is located, the straight line where the second direction Y is located, and the straight line where the third direction P is located can form a right triangle shape. It can be understood that this example only shows a preferred example of the transmission mode and transmission track of the mutual transmission among the first transmission assembly 400, the first clamping assembly 200, and the second clamping assembly 300, and does not constitute a limitation on the motion mode and motion track for realizing the mutual transmission among the three.

[0045] Such as Figures 1 to 3 And Figure 5As shown, in a possible implementation, the first clamping assembly 200 includes a first stopper 210, a first connecting member 220, and a first movable member 230. The first stopper 210 is disposed on the base 100, and a stopper portion 211 and a movable groove body 212 are provided on a side away from the base 100. The stopper portion 211 is disposed on a side of the movable groove body 212 close to the first mounting groove; the first connecting member 220 passes through the first stopper 210 and is inserted into the first transmission assembly 400; the first movable member 230 is received in the movable groove body 212 and is movably connected to the first transmission assembly 400 through the first connecting member 220. A first clamping end of the first movable member 230 is disposed opposite to the stopper portion 211.

[0046] In this embodiment, the specific configuration of the first clamping assembly 200 is optimized. Specifically, the first clamping assembly 200 is configured as a combined component at least including a first stopper 210, a first connecting member 220, and a first movable member 230. The first stopper 210 may be a plate-like structure with a certain thickness, which can be directly connected to the top end of the base 100 through fasteners such as screws / bolts; alternatively, a sunk groove may be provided at the top end of the base 100 first, and then the first stopper 210 is placed in the sunk groove to enable quick alignment between the two, and finally it is fixed to the base 100 through fasteners such as screws / bolts to improve the assembly efficiency and connection fastening effect between the first stopper 210 and the base 100; a movable groove body 212 is provided at the top end of the first stopper 210. The movable groove body 212 may be a nearly rectangular groove extending along the third direction P. A stopper portion 211 protruding upward is provided on one side of the movable groove body 212 facing the first mounting groove. The stopper portion 211 is used to cooperate with the first movable member 230 to form a jaw structure of the first clamping assembly 200; the stopper portion 211 may be integrally formed with the first stopper 210 to reduce the problem of connection looseness caused by the abutment stress during clamping and improve the clamping stability and reliability. The first connecting member 220 may be a long screw / a long pin / a long bolt. Its top end can be fixedly connected to the first movable member 230 through a connecting hole, and the bottom end is suspended and can be movably inserted into the second limiting waist-shaped hole 402 of the first transmission assembly 400. An avoidance window corresponding to the second limiting waist-shaped hole 402 is provided on the base 100, and the middle part of the first connecting member 220 is movably inserted into the avoidance window; it should be noted that the straight line where the extending direction of the second limiting waist-shaped hole 402 is located and the straight line where the extending direction of the first limiting waist-shaped hole 401 is located are arranged in a horn shape on the first transmission member 420, and the horn opening facing the second transmission member 430 is larger than the horn opening away from the second transmission member 430. The first movable member 230 may be a nearly wrench-shaped structure. One end facing the stopper portion 211 is the first clamping end, and the first clamping end is a jaw structure; a soft rubber sleeve may be sleeved or pasted on the outside of the jaw. When the first movable member 230 abuts against the special-shaped end of the workpiece to be processed, it can provide a buffering effect to offset / slow down the abutment stress; the other end away from the stopper portion 211 is a long strip plate, and the first connecting member 220 is connected to the long strip plate. The first clamping assembly 200 provided in this example has a simple structure, high clamping accuracy, long service life, is convenient for processing, and has low cost.

[0047] In an example, such as Figure 5, an elastic groove 231 is provided on the first movable member 230. The elastic groove 231 extends along the third direction P and does not extend out of the jaws of the first movable member 230. The first clamping assembly 200 further includes a positioning member 240 and a first elastic member 250. The positioning member 240 can be a positioning pin, which passes through the elastic groove 231 and is fixedly connected to the movable groove body 212 of the first stop member 210. In this way, on the one hand, the moving stroke of the first movable member 230 can be restricted by the positioning member 240 to prevent the first movable member 230 from abutting against the stop portion 211 excessively and causing the breakage of the stop portion 211, thereby improving the clamping reliability of the first clamping assembly 200; on the other hand, it can cooperate with the movable groove body 212 to make the first movable member 230 reciprocate along the third direction P, improving the moving accuracy and clamping accuracy. The first elastic member 250 can be a spring, and its two ends respectively abut against the positioning member 240 and the inner end wall of the elastic groove 231, and are used to provide an elastic force for the first movable member 230 to abut against the stop portion 211, enhancing the clamping force on the special-shaped end and improving the clamping and fixing effect. The first clamping assembly 200 provided in this example can quickly respond to the clamping operation of the special-shaped end and has a better clamping and fixing effect on the special-shaped end.

[0048] In one example, as Figures 1 to 3 , the first clamping assembly 200 further includes a top plate 260. The size of the top plate 260 is smaller than that of the first stop member 210, and it can be embedded in the top sink of the first stop member 210 and then fixedly connected to the first stop member 210 through the positioning member 240. The top plate 260 at least covers a part of the elastic groove 231 of the first movable member 230 in the third direction P to prevent dust / foreign objects from entering the elastic groove 231 and causing blockage of the elastic groove 231, or water droplets from accumulating on the first elastic member 250 and causing rust and corrosion of the first elastic member 250, improving the smoothness and silkiness of the use of the first clamping assembly 200.

[0049] As Figures 1 to 3 and Figure 5 shown, in a possible implementation manner, the second clamping assembly 300 includes a second stop member 310, a second connecting member 320 and a second movable member 330. The second stop member 310 is provided on the base 100. The second movable member 330 is movably provided on the base 100 and is respectively arranged on opposite sides of the first installation groove with the second stop member 310. The second movable member 330 is connected to the first transmission assembly 400 through the second connecting member 320.

[0050] In this embodiment, the specific configuration of the second clamping assembly 300 is optimized. Specifically, the second clamping assembly 300 is configured as a composite component including at least a second stopper 310, a second connecting member 320 and a second movable member 330. The second stopper 310 may be a block structure, which may be connected to the top of the base 100 by fasteners such as screws / bolts; the second stopper 310 is arranged on one side of the tail end of the first mounting groove. The second connecting member 320 may be a long screw / long pin / long bolt, which extends along the thickness direction Z of the base 100, and the two ends are respectively fixedly connected to the second transmission member 430 and the second movable member 330, so as to form a force constraint on the second movable member 330 and the second transmission member 430 in this direction, prevent the second movable member 330 from being separated from the second transmission member 430 during the movement, realize the stable transmission of the second transmission member 430, and improve the reliability of the synchronous transmission of the second movable member 330 and the first movable member 230. The second movable member 330 may be a nearly rectangular slider structure, which is bounded by the second connecting member 320 on the top surface of the base 100 and can slide on the plane, and is arranged opposite to the second stopper 310 on the other hand, and can clamp or release with the second stopper 310 during the movement, forming a clamping claw structure of the second clamping assembly 300. The second clamping assembly 300 provided in this example has a simple structure, high tracking accuracy and reliability, and good clamping effect.

[0051] like Figure 1 and Figure 2 In a possible embodiment, the base 100 also has a second mounting groove connected to the first mounting groove, and the clamping tool 20 also includes a third clamping assembly 500 arranged near the second mounting groove. The third clamping assembly 500 is movably arranged on the base 100 and is located on a side of the second clamping assembly 300 away from the first clamping assembly 200.

[0052] In this embodiment, the specific configuration of the clamping tool 20 is further optimized. Specifically, the clamping tool 20 is configured as a composite component including at least a base 100, a first clamping assembly 200, a second clamping assembly 300, a first transmission assembly 400 and a third clamping assembly 500. The third clamping assembly 500 is used to clamp the non-special-shaped end of the workpiece to be processed, and cooperates with the first clamping assembly 200 and the second clamping assembly 300 to achieve clamping and fixing of the non-bending end of the workpiece to be processed, providing a stable and favorable bending environment for the bending end of the workpiece to be processed, which is conducive to improving the bending effect and the processing yield of the workpiece to be processed. The clamping tool 20 provided in this example can achieve clamping and fixing of the workpiece to be processed at least in three positions, with high clamping accuracy, strong clamping stability and good clamping reliability.

[0053] like Figure 6 and Figure 7As shown, in a possible implementation, the third clamping assembly 500 includes a clamping base 510, a clamping arm 520 and a locking member 530. A clamping groove 501 is provided on the clamping base 510. The clamping groove 501 communicates with the second installation groove. The clamping arm 520 is rotatably connected to the clamping base 510. The locking member 530 is used to lock the clamping arm 520 and the clamping base 510.

[0054] In this embodiment, the specific configuration of the third clamping assembly 500 is optimized. Specifically, the third clamping assembly 500 is configured to at least include a clamping base 510, a clamping arm 520 and a locking member 530. The clamping base 510 can be a plate-like structure with a certain thickness, which extends along the second direction Y of the base 100 and has a certain span in the first direction X of the base 100. A clamping groove 501 is provided on the top surface of the clamping base 510. The clamping groove 501 is adapted to the shape of the non-abnormal end of the workpiece to be machined. When the workpiece to be machined is inserted into the clamping groove 501, the workpiece to be machined can be restricted from shifting on the clamping base 510. The clamping arm 520 can be a clamping plate structure, with a handle at its free end and the other end rotatably connected to the clamping base 510 through a hinge seat. The clamping arm 520 extends along the second direction Y of the base 100 and has a clamping width that expands along the first direction X to cooperate with the clamping base 510 to clamp or release the workpiece to be machined placed in the clamping groove 501. The locking member 530 can be a buckle structure or a bolt structure, which is used to lock the clamping arm 520 and the clamping base 510 in the clamped state to clamp and fix the non-abnormal end of the workpiece to be machined. The third clamping assembly 500 provided in this example can arrange non-linear clamping grooves 501 in the first direction X and the second direction Y of the base 100, so as to realize large-area clamping of the workpiece to be machined, and the clamping and fixing effect is better.

[0055] As Figure 1 shown, in a possible implementation, the base 100 includes a first base body 110 and a second base body 120 that are overlapped. The first clamping assembly 200 and the second clamping assembly 300 are spaced apart on the first base body 110, and the first transmission assembly 400 is inserted into the second base body 120.

[0056] In this embodiment, the specific configuration of the base 100 is optimized. Specifically, the base 100 is configured to include at least a first base body 110 and a second base body 120. The first base body 110 may be a near-rectangular plate-like structure with a certain thickness, on which there are provided a hollow mounting window, a hollow first mounting groove and a second mounting groove. The first mounting groove, the second mounting groove and the mounting window are arranged in sequence along the first direction X of the base 100. The first clamping assembly 200, the second clamping assembly 300 and the third clamping assembly 500 are arranged in sequence along the first direction X of the base 100. The first clamping assembly 200 and the second clamping assembly 300 are respectively arranged near the head and the tail of the first mounting groove. The third clamping assembly 500 is arranged at the mounting window, and the clamping groove 501 thereon communicates with the second mounting groove, jointly forming a receiving groove for receiving the workpiece to be processed. The second base body 120 is arranged below the first base body 110, and its size is equivalent to that of the first base body 110. The two can be connected and fastened in the thickness direction Z of the base 100 through fasteners such as screws / bolts. The first transmission assembly 400 is arranged on the side of the second base body 120 facing the first base body 110. At this time, the groove body for receiving the first transmission assembly 400 is distributed on the second base body 120, and the bottom surface of the first base body 110 serves as the limiting upper surface of the first transmission assembly 400. Alternatively, the first transmission assembly 400 can also be arranged at the connection between the second base body 120 and the first base body 110. At this time, the groove body for receiving the first transmission assembly 400 is distributed between the top end of the second base body 120 and the bottom end of the first base body 110 at the same time. The split base 100 provided in this example is convenient for the assembly of the first transmission assembly 400, the first clamping assembly 200 and the second clamping assembly 300, and is also convenient for processing, with low cost and is conducive to large-scale production.

[0057] In a possible implementation manner, the first mounting groove has a back hook portion. The head end and the tail end of the first mounting groove are located on the same side of the back hook portion, and the head end of the first mounting groove is located between the tail end of the first mounting groove and the back hook portion.

[0058] In this embodiment, the specific configuration of the first installation groove is optimized. Specifically, the first installation groove is configured as a hook-shaped structure with a swing zone so that it is adapted to the size of the edge of the special-shaped end of the workpiece to be processed; at the same time, the setting of the hook portion also makes the head and tail ends of the first installation groove on the same side, and the first clamping assembly 200 position at the head end of the first installation groove and the second clamping assembly 300 position at the tail end of the first installation groove can be reasonably arranged. On the one hand, the two are in a position where they will not interfere with each other during clamping or loosening operations, ensuring the safety of simultaneous clamping or loosening; on the other hand, the distance between the two can be minimized to achieve the purpose of shortening the transmission stroke of the first transmission assembly 400, thereby shortening the response time difference of the clamping / loosening action at the head and tail ends, avoiding the situation where one end is clamped and the other end is not clamped, so that the clamping tool 20 can clamp or loosen the head and tail ends of the special-shaped end at the same time, improve the reliability and stability of the simultaneous clamping / loosening operation of different positions of the special-shaped end, and the clamping and fixing effect is better.

[0059] In addition, if Figure 1 As shown, an embodiment of the present application also provides a bending device, including a bending mechanism 10 and the clamping tool 20 as described above, the bending mechanism 10 is movably arranged on a base 100 of the clamping tool 20, and is located on a side of the second clamping component 300 of the clamping tool 20 away from the first clamping component 200.

[0060] In this embodiment, in order to achieve accurate clamping and accurate bending of the workpiece to be processed, so as to obtain an FPC molded product with high bending accuracy and good pre-bending effect, the bending equipment is configured as a combined component including at least a bending mechanism 10 and a clamping tool 20. The bending mechanism 10 can be a reversible structure, which can be connected and fixed to the base 100 by fasteners such as screws / bolts, or can be set on the base 100 by structures such as buckles / mortise and tenon joints; in the direction from the clamping and fixing area of ​​the FPC cable to the cable bending area, the second clamping assembly 300 is located between the first clamping assembly 300 and the second clamping assembly 301. The first clamping assembly 200 is located at the rear side of the second clamping assembly 300, and the bending mechanism 10 is located at the rear side of the third clamping assembly 500. At the same time, the first clamping assembly 200 is used to clamp the head end of the irregular end of the workpiece to be processed, the second clamping assembly 300 is used to clamp the tail end of the irregular end of the workpiece to be processed, and the third clamping assembly 500 is used to clamp the non-irregular part of the workpiece to be processed. The bending mechanism 10 is used to turn over and bend the bent end of the workpiece to be processed after clamping and fixing, so as to obtain an FPC bent and formed product with good bending effect. Since the clamping fixture 20 has a good clamping and fixing effect on the irregular end and non-irregular part of the FPC cable, it is not easy to cause cable crushing, so that the bending mechanism 10 has high turning and bending accuracy, good bending effect, high yield rate of the overall formed product, and high processing efficiency.

[0061] In addition, ifFigure 1 and Figure 2 , the specific structure of the clamping tooling 20 refers to the above embodiments. Since the clamping tooling 20 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0062] As Figures 6 to 8 shown, in a possible implementation manner, the bending mechanism 10 includes a pressing member 11, a second transmission assembly 12 and a flipping bracket 13, and the pressing member 11 is in transmission connection with the flipping bracket 13 through the second transmission assembly 12.

[0063] In this embodiment, the specific configuration of the bending mechanism 10 is optimized. Specifically, the bending mechanism 10 is configured to include at least a combined component of a pressing member 11, a second transmission assembly 12 and a flipping bracket 13. The pressing member 11 can be a pressing mechanical button, and a clamping notch is arranged thereon, and the clamping notch faces the second transmission assembly 12. The second transmission assembly 12 can be a gear-rack meshing transmission structure, which is clamped with the clamping notch on the pressing member 11. The flipping bracket 13 can be a cross beam frame extending along the second direction Y, and it is in transmission connection with the second transmission assembly 12 and can rotate synchronously under the transmission of the second transmission assembly 12, so as to realize the flipping and bending of the FPC flexible cable fixed thereon, and realize the bending and forming of the FPC flexible cable product. The pressing member 11 has a locking state and an open state. In the locking state, the clamping notch thereon clamps the second transmission assembly 12. At this time, the second transmission assembly 12 and the flipping bracket 13 are in a normal flat position; in the open state, the clamping notch thereon moves downward to avoid the second transmission assembly 12, the second transmission assembly 12 moves and drives the flipping bracket 13 to flip, and the flipping bracket 13 drives the FPC flexible cable fixed thereon to fold, realizing the bending and forming of the FPC flexible cable.

[0064] In an example, as Figures 6 to 8, the second transmission component 12 is configured to include at least a combined component of a gear 1201, a rack 1202, a second elastic member 1203, an elastic seat 1204, and a handle 1205. The gear 1201 can be engaged above the rack 1202; the elastic seat 1204 is spaced on one side of the rack 1202 and is at the same horizontal position as the rack 1202; the second elastic member 1203 can be a spring, which is arranged between the elastic seat 1204 and the rack 1202 to provide a driving force for the rack 1202 to move forward; one end of the handle 1205 is arranged on the rack 1202, and the other end extends out of the bending mechanism 10. An operator can restore the moved rack 1202 to its original position through the handle 1205. The clamping notch of the pressing member 11 can be clamped to the rack 1202 to realize the position limitation of the rack 1202; the flipping bracket 13 is connected to the axial direction of the gear 1201 and can rotate synchronously with the gear 1201.

[0065] In one example, such as Figure 6 and Figure 7 , the flipping bracket 13 is configured to include at least a combined component of a support 1301 and a bearing beam 1302. Two supports 1301 can be provided, and the two supports 1301 are spaced on the base 100 along the second direction Y of the base 100. Both ends of the bearing beam 1302 are respectively rotatably connected to the two supports 1301, and the axial end of the bearing beam 1302 is connected to the axial end of the gear 1201 to drive it to rotate synchronously through the gear 1201; a magnet is arranged on the bearing beam 1302 to adsorb and fix the FPC flexible cable, with strong connection tightness, which can effectively prevent the FPC flexible cable from shifting during the flipping process and improve the flipping and bending effect of the FPC flexible cable.
