[0029] See also Figures 1 to 5 A conductive contact composite molding device according to an embodiment of the present invention comprises: a punching die 100, a bending mechanism 200 and a conveying mechanism, wherein the punching die 100 comprises a lower die assembly 110 and an upper die assembly 120 movable and lifting relative to the lower die assembly 110, wherein the lower die assembly 110 is used to carry a long strip 10, and the conveying mechanism is used to drive one end of the long strip 10 to extend out of the output end of the punching die 100, and the bending mechanism 200 is arranged at the output end of the punching die 100, and when the upper die assembly 120 presses down on the lower die assembly 110 to cut the portion of the long strip 10 close to the output end of the punching die 100 according to a certain length to form a strip sheet 20, the bending mechanism 200 can bend the free end of the strip sheet 20 extending out of the punching die 100 into a preset shape to form a conductive contact.

[0030] The conductive contact composite molding device of the above structure utilizes the upper mold assembly 120 and the lower mold assembly 110 of the punching mold 100 to punch out the long strip 10 to form a strip sheet 20 for forming a conductive contact. While the upper mold assembly 120 and the lower mold assembly 110 clamp the strip sheet 20, the bending mechanism 200 bends the portion of the strip sheet 20 extending out of the punching mold 100 into a preset shape, so that the stamping and bending processes are formed under the same positioning reference, thereby ensuring the processing accuracy of the conductive contact. In addition, the conductive contact composite molding device has a simple structure and low cost, and has a high material utilization rate when manufacturing conductive contacts, thereby avoiding a large amount of material waste. It should be noted that the conveying mechanism is used to intermittently drive the long strip 10 to feed and move a certain distance in the direction of the bending mechanism 200. The distance of a single movement of the long strip 10 is the length of a piece of strip sheet 20. When the upper mold assembly 120 is away from the lower mold assembly 110, the formed conductive contact sheet can leave the bending mechanism 200 under the action of the conveying mechanism or an external robot or its own gravity.

[0031] See also Figure 1 In some embodiments of the present invention, the bending mechanism 200 includes a downward pressing assembly 210 and a side pressing assembly 220, wherein the downward pressing assembly 210 is used to bend the strip sheet 20 downward to form a corner portion, and the side pressing assembly 220 is used to bend the free end of the strip sheet 20 into a preset shape, and the downward pressing assembly 210 is connected to the side pressing assembly 220 through a first linkage mechanism 300 so that the downward pressing assembly 210 and the side pressing assembly 220 act sequentially. It can be understood that after the downward pressing assembly 210 moves downward to form a corner portion on the strip sheet 20, the side pressing assembly 220 is driven by the first linkage mechanism 300 to act so as to bend the free end of the strip sheet 20 into a preset shape, ensuring that the downward pressing assembly 210 and the side pressing assembly 220 produce continuous actions, which not only meets the manufacturing needs of the conductive contact sheet, but also ensures that the corner portion and the end of the conductive contact sheet are formed under the same positioning reference, thereby ensuring the processing accuracy.

[0032] See also Figure 2 and Figure 5In some embodiments of the present invention, the down-pressing assembly 210 includes a supporting member 211 and a longitudinal slider 212 movably disposed above the supporting member 211, the supporting member 211 having a supporting plane 2111 for supporting the strip-shaped sheet 20 and a molding side surface 2112 for molding the corner portion and the end shape of the conductive contact, the longitudinal slider 212 is provided with a corner molding member 213 protruding from its lower end, and the side-pressing assembly 220 includes a transverse slider 221, and the side wall of the transverse slider 221 close to the supporting member 211 is protrudingly provided with a protrusion located at the corner molding member The first linkage mechanism 300 includes a downward pressing driving member 310, which is connected to the longitudinal slider 212 via a longitudinally arranged first elastic member 320 to drive the longitudinal slider 212 to move downward, and a first inclined surface 330 inclined from bottom to top toward the longitudinal slider 212 is provided on the side of the transverse slider 221 away from the lateral bending member 222, and the downward pressing driving member 310 is connected to a lifting block 340 extending downward, and a second inclined surface 350 matching the first inclined surface 330 is provided at the lower end of the lifting block 340. It should be noted that, see Figures 2 to 4 When the downward driving member 310, the first elastic member 320 and the longitudinal slider 212 move downward together, the longitudinal slider 212 presses downward against the supporting plane 2111, and the corner forming member 213 bends the strip sheet 20 to form a corner portion. As the downward driving member 310 continues to move downward, the first elastic member 320 is compressed, and the longitudinal slider 212 keeps contacting the supporting plane 2111. The lifting block 340 follows the downward driving member 310 and descends to the second inclined surface 350 to contact the first inclined surface 330 of the transverse slider 221. As the second inclined surface 350 moves vertically downward, the transverse slider 221 is pushed until the side bending part 222 presses against the free end of the strip sheet 20 and bends to form a preset shape. The construction of the pressing assembly 210, the bending mechanism 200 and the first linkage mechanism 300 of the above structure is very simple, and the pressing assembly 210 and the side pressing assembly 220 can be operated successively with a simple structure and action mode, which not only meets the manufacturing needs of the conductive contact sheet, but also ensures that the corner portion and the end portion of the conductive contact sheet are formed under the same positioning reference, thereby ensuring the processing accuracy.

[0033] See also Figure 1 and Figure 5In some embodiments of the present invention, the bending mechanism 200 further comprises a mounting seat 400 disposed at the output end of the punching die 100, the down-pressing assembly 210 and the side-pressing assembly 220 are both disposed on the mounting seat 400, a horizontally extending rod 500 is connected to the side of the transverse slider 221 away from the side bending component 222, the mounting seat 400 is provided with a stop guide block 410 opposite to the side of the transverse slider 221 away from the side bending component 222, the end of the rod 500 is movably inserted into the stop guide block 410, and the end of the rod 500 is in contact with the stop guide block 410. A return spring 510 is provided between the guide blocks 410 to drive the transverse slider 221 to slide against the stop guide block 410. A clearance groove 341 with a downward opening for the rod 500 to pass through is horizontally penetrated through the lower part of the lifting block 340. The lifting block 340 can move downward along the side wall of the stop guide block 410 close to the transverse slider 221, so as to push the side bending component 222 to move close to the supporting component 211 through the cooperation of the second inclined surface 350 and the first inclined surface 330, and make the rod 500 enter the clearance groove 341. In this embodiment, the lifting block 340 is roughly in the shape of a vertically arranged quadrangular prism, and the second inclined surface 350 is inclined upward from the lower end surface of the lifting block 340. It can be understood that, see Figure 1 When the punching die 100 is opened, the transverse slider 221 moves to abut against the side wall of the stop guide block 410 under the action of the return spring 510. At this time, the lifting block 340 is located directly above the transverse slider 221 so that the second inclined surface 350 and the first inclined surface 330 are arranged opposite to each other. The side wall of the lifting block 340 away from the supporting member 211 abuts against the side wall of the stop guide block 410 close to the transverse slider 221, so that the stop guide block 410 plays a role in guiding the lifting and lowering movement of the lifting block 340. Figure 2 or Figure 3 During the closing process of the punching die 100, the lifting block 340 follows the pressing driving member 310 to descend until the second inclined surface 350 contacts the first inclined surface 330 of the horizontal slider 221. As the second inclined surface 350 moves vertically downward, the horizontal slider 221 slides toward the supporting member 211 to move away from the stop guide block 410, see Figure 4 , until the lifting block 340 separates the lateral slider 221 from the stop guide block 410, under the action of the return spring 510, the lateral slider 221 and the stop guide block 410 clamp the lifting block 340 to stabilize the side bending component 222 against the position of the strip sheet 20, during which the rod 500 enters the clearance groove 341 from the lower opening of the clearance groove 341, and the rod 500 moves laterally relative to the stop guide block 410 and the clearance groove 341 toward the supporting member 211, thereby compressing the return spring 510. Figure 1When the upper mold assembly 120 moves upward away from the lower mold assembly 110, the lifting block 340 moves upward, and under the action of the return spring 510, the first inclined surface 330 abuts against the second inclined surface 350. When the second inclined surface 350 is completely separated from the first inclined surface 330, the transverse slider 221 abuts against the side wall of the stop guide block 410. Generally speaking, since the side of the transverse slider 221 close to the supporting member 211 is used to set the side bending component 222, and the side of the transverse slider 221 opposite to the side bending component 222 is supported by the lifting block 340, resulting in a place for the return spring 510 that drives the transverse slider 221 to return to its original position. The above technical solution cleverly solves this problem.

[0034] See also Figure 4 and Figure 5 , wherein the mounting seat 400 is provided with a sliding hole extending along the width direction of the strip sheet 20, the supporting member 211 is telescopically movable along the sliding hole, the supporting member 211 is connected to a cylinder, the cylinder drives the supporting member 211 to extend to the bottom of the strip sheet 20 to support the strip sheet 20, when the bending mechanism 200 completes the work, the longitudinal slider 212 moves away from the supporting member 211 upward, and the transverse slider 221 moves away from the supporting member 211 from the side, at this time, the cylinder drives the supporting member 211 to retract so that the formed conductive contact sheet can fall. Specifically, the length dimension of the portion of the strip sheet 20 extending from the punching die 100 is greater than the portion of the strip sheet 20 located on the punching die 100, so when the strip sheet 20 is cut, the formed conductive contact sheet can fall under its own gravity, and there is no need to set up an external manipulator to unload the conductive contact sheet, which is conducive to further simplifying the structure of the conductive contact sheet composite molding device and reducing costs. In other embodiments, the cylinder can also be replaced by other linear actuators such as electric push rods. The electric push rods and the conveying mechanism are both connected to the control module. Before the conveying mechanism conveys the long strip 10 to the direction of the bending mechanism 200 by a distance of a strip sheet 20, the control module controls the electric push rods to extend the supporting member 211. In this embodiment, the supporting member 211 is columnar, and the mounting seat 400 includes a vertically placed plate. The sliding hole is set through the plate and is consistent with the cross-sectional shape of the supporting member 211. The sliding hole is used to guide the telescopic movement of the supporting member 211.

[0035] See also Figure 5In some embodiments of the present invention, the longitudinal slider 212 is connected to a pressing block 215 elastically extending from the lower end of the longitudinal slider 212 through a second elastic member 214, and the pressing block 215 presses the strip sheet 20 against the supporting plane 2111. The lower end surface of the longitudinal slider 212 is recessed upward to form a first limiting groove 216, and the pressing block 215 can compress the second elastic member 214 to completely enter the first limiting groove 216. It should be noted that since the corner forming member 213 protrudes from the lower end of the longitudinal slider 212, in the process of the longitudinal slider 212 moving downward to contact the strip sheet 20, the corner forming member 213 first contacts the strip sheet 20, resulting in the portion of the strip sheet 20 corresponding to the supporting plane 2111 not being positioned, and at this time, the portion of the strip sheet 20 facing the supporting plane 2111 is prone to irregular deformation, resulting in manufacturing deviations at the corners of the strip sheet 20. In the above structure, the pressing block 215 extends downward from the bottom of the corner forming member 213 under the action of the second elastic member 214. During the downward movement of the longitudinal slider 212, the pressing block 215 first contacts the supporting plane 2111 of the supporting member 211, thereby clamping the strip sheet 20, and then the corner forming member 213 contacts the strip sheet 20. During this process, the pressing block 215 can compress the second elastic member 214 to enter the first limiting groove 216. When the corner forming member 213 bends the strip sheet 20 to form a corner portion, the lower end surface of the pressing block 215 is flush with the lower end surface of the longitudinal slider 212.

[0036] See also Figure 5 In some embodiments of the present invention, in order to ensure the shape accuracy of the end of the conductive contact sheet, the side bending component 222 includes a first top block 223 and a second top block 224 which are arranged on the horizontal slider 221 at an upper and lower interval, the first top block 223 corresponds to the strip sheet 20 near the corner, and the second top block 224 corresponds to the free end of the strip sheet 20. The first top block 223 is connected to the horizontal slider 221 through a third elastic member 225, and the third elastic member 225 can drive the first top block 223 to extend out of the end of the second top block 224, that is, in the process of the horizontal slider 221 moving close to the supporting member 211, the first top block 223 first contacts the part of the strip sheet 20 near the corner to play a positioning effect, and then the first top block 223 moves a certain distance in the direction of compressing the third elastic member 225, and the second top block 224 contacts the end of the strip sheet 20, thereby bending the end of the strip sheet 20 into a preset shape, thereby obtaining a conductive contact sheet with higher shape accuracy.

[0037] See also Figure 5In some embodiments of the present invention, the transverse slider 221 is provided with an active channel penetrating the side wall of the transverse slider 221 near the longitudinal slider 212, the first top block 223 is slidably arranged in the active channel, the side of the first top block 223 is provided with a limiting protrusion 226, the active channel is provided with a second limiting groove 227 matched with the limiting protrusion 226 to limit the sliding stroke of the first top block 223, and the third elastic member 225 is located in the active channel to drive the end of the first top block 223 to contact the strip sheet 20 before the end of the second top block 224. The second limiting groove 227 and the limiting protrusion 226 cooperate to define the longest distance and the shortest distance of the first top block 223 extending relative to the transverse slider 221. When the first top block 223 is at the shortest distance extending from the transverse slider 221, the first top block 223 can rigidly press the position of the strip sheet 20 near the corner onto the supporting member 211.

[0038] See also Figure 3 or Figure 4 In some embodiments of the present invention, the longitudinal slider 212 includes a first block and a first cover, the first block is provided with a first mounting groove for mounting the side opening of the corner molding 213, and the first cover is detachably connected to the first block to close the side opening of the first mounting groove; the transverse slider 221 includes a second block and a second cover, the second block is provided with a second mounting groove for mounting the side opening of the side bending component 222, and the second cover is detachably connected to the second block to close the side opening of the second mounting groove. It is understandable that when the specifications of the produced conductive contact sheet change, the user can remove the first cover and the second cover, and then adjust the production and processing by replacing the corner molding 213 and the side bending component 222.

[0039] See also Figure 1 , Figure 2 In some embodiments of the present invention, the upper die seat of the upper die assembly 120 has an overhanging plate portion extending horizontally toward the bending mechanism 200, and the overhanging plate portion constitutes the downward pressure driving member 310. It can be understood that when the upper die seat moves downward to achieve the mold closing of the upper die assembly 120 and the lower die assembly 110, the downward pressure driving member 310 also moves downward synchronously to drive the downward pressure assembly 210 and the side pressure assembly 220 to work successively, which not only eliminates the action delay problem between the punching die 100 and the bending mechanism 200, ensures that the strip sheet 20 is bent while being punched, but also does not need to be additionally configured with a driving source to drive the downward pressure driving member 310 to move up and down, which ingeniously simplifies the structure, reduces costs, and can obtain better processing accuracy.

[0040] See also Figure 1In some embodiments of the present invention, the lower mold assembly 110 is provided with a plurality of side stoppers 130 for limiting the two side edges of the long material strip 10 at intervals along the conveying direction of the long material strip 10, and a plurality of punching assemblies 140, trimming assemblies 150 and cutting assemblies 160 are provided between the lower mold assembly 110 and the upper mold assembly 120. In this embodiment, the lower mold assembly 110 is provided with a plurality of side stoppers 130 arranged at intervals along the conveying direction of the long material strip 10 on both sides of the long material strip 10, the conveying mechanism pushes the long material strip 10 to move toward the bending mechanism 200, the punching assembly 140 can form the positioning holes required for the conductive contact sheet on the long material strip 10, and the trimming assembly 150 can remove part of the material at the side edge of the long material strip 10 to obtain a strip sheet 20 of a corresponding shape, so as to be supplied to the bending mechanism 200 for bending to obtain the conductive contact sheet. Of course, in other embodiments, the components of the cutting mold can be adjusted accordingly, and corresponding functional components can be increased or reduced.
