[0043] refer to Figure 5 and Figure 6 , both ends of each feeding piece 31 are fixedly connected to a first guide rod 37, and both ends of each pressing piece 32 are fixedly connected to a second guide rod 38. The two feeding pieces 31 are slidably connected in the two groups of first guide grooves 35 through the corresponding two first guide rods 37, and the two pressing pieces 32 are slidably connected in the two groups of second guide grooves 36 through the corresponding two second guide rods 38. The two guide plates 34 are provided with a driving groove 39 arranged in a through shape at one end along the feeding direction of the material belt, and each driving groove 39 is connected to the corresponding two first guide grooves 35 and the two second guide grooves 36.

The two first guide rods 37 on each feeding piece 31 are fixedly connected to the first limiting slider 313 at one end away from each other, and each first limiting slider 313 is slidably connected in the corresponding first limiting groove 311. The two second guide rods 38 on each pressing piece 32 are fixedly connected to the second limiting slider 314 at one end away from each other, and each second limiting slider 314 is slidably connected in the corresponding second limiting groove 312.

[0044] refer to Figure 4-Figure 6, the two guide plates 34 are each provided with a third guide groove 315, and the bottom of the upper mold 21 is fixedly connected with two mounting plates 316 corresponding to the positions of the two guide plates 34, and the two mounting plates 316 are each fixedly connected with a third guide rod 317 slidably connected to the corresponding third guide groove 315; when the upper mold 21 moves upward, the third guide rod 317 can be driven to slide in the third guide groove 315 through the mounting plate 316, and the guide plate 34 can be driven to move toward the feeding direction of the material strip through the cooperation between the third guide rod 317 and the third guide groove 315.

[0045] A rotating groove 318 is provided on the side where the two feeding parts 31 are close to each other, and a pressure roller 319 is rotatably connected in the two rotating grooves 318. Both ends of the two pressure rollers 319 are fixedly connected to a ratchet 320. Two sliding grooves 321 corresponding to the positions of the corresponding ratchet wheels 320 are provided inside the two rotating grooves 318. A ratchet pawl 322 capable of cooperating with the corresponding ratchet wheel 320 is slidably connected inside each sliding groove 321, and an elastic member 323 is connected between the end of each ratchet pawl 322 away from the ratchet wheel 320 and the corresponding sliding groove 321.

[0046] When the guide plate 34 moves along the feeding direction of the material belt, the first limiting groove 311 can limit the first limiting slide block 313, so that the first limiting slide block 313 can only slide up and down in the first limiting groove 311, so that the two feeding pieces 31 can slide along the two groups of first guide grooves 35 through the corresponding two first guide rods 37, and the two feeding pieces 31 gradually approach each other and then clamp the material belt to move.

[0047] When the guide plate 34 moves along the feeding direction of the material belt, the second limiting groove 312 can limit the second limiting slide block 314, so that the second limiting slide block 314 can only slide up and down in the second limiting groove 312, so that the two pressing pieces 32 can slide along the two groups of second guide grooves 36 through the corresponding two second guide rods 38, and the two pressing pieces 32 gradually move away from each other to release the pressure on the material belt.

[0048] During actual stamping work, refer to Figure 8 When the upper mold 21 moves from bottom to top, the upper mold 21 can drive the two mounting plates 316 and the two third guide rods 317 to move upward, so that the two third guide rods 317 can slide in the corresponding third guide grooves 315, and the two guide plates 34 are driven to move toward the feeding direction of the material strip through the cooperation between the two third guide rods 317 and the corresponding third guide grooves 315.

[0049] When the two guide plates 34 move toward the feeding direction of the material belt, the two first limit grooves 311 can limit the corresponding first limit sliders 313 and provide pulling force, so that the first limit sliders 313 can only slide up and down in the corresponding first limit grooves 311, thereby driving the two feeding pieces 31 to slide along the two groups of first guide grooves 35 under the guiding action of the corresponding two first guide rods 37, so that the two feeding pieces 31 gradually approach each other to clamp and feed.

[0050] At the same time, the two second limit grooves 312 can limit the corresponding second limit sliders 314 and provide pulling force, so that the second limit sliders 314 can only slide up and down in the corresponding second limit grooves 312, thereby driving the two pressing pieces 32 to slide along the two groups of second guide grooves 36 under the guidance of the corresponding two second guide rods 38, so that the two pressing pieces 32 gradually move away from each other and release the pressure on the material belt, thereby not affecting the feeding.

[0051] refer to Figure 7 When the upper mold 21 moves from top to bottom, the two third guide rods 317 can cooperate with the corresponding third guide grooves 315 to drive the two guide plates 34 to move in the feeding direction away from the material belt. The two guide plates 34 can provide thrust for the corresponding first limiting slide block 313 and the corresponding second limiting slide block 314 through the first limiting groove 311 and the second limiting groove 312, so that the two feeding members 31 slide along the two sets of first guide grooves 35 under the guidance of the corresponding two first guide rods 37 and gradually return to the initial position. At the same time, the two pressing members 32 will move in the opposite direction. Under the guidance of the two second guide rods 38, they slide along the two groups of second guide grooves 36, so that the two pressing pieces 32 return to the initial position to press the material strip, so that the material strip cannot move during the stamping process, thereby ensuring that the material strip remains stable in the mold 2, preventing the material strip from sliding during the stamping process, ensuring the accuracy of the stamping position, reducing dimensional errors and elastic deformation caused by the movement of the material strip, thereby improving the accuracy and consistency of the conductive sheet 4, and so on. The feeding component 3 can feed the material strip synchronously during the process of the mold 2 stamping the material strip.

[0052] To sum up, through the setting of the feeding piece 31, when the upper mold 21 moves from bottom to top, the two feeding pieces 31 can gradually approach each other and clamp the material strip for feeding, so that the feeding component 3 can feed the material strip synchronously during the process of the mold 2 stamping the material strip, which helps to maintain the consistency of the rhythm during the stamping process, so that the feeding of the material strip and the stamping action of the mold 2 are continuous and coordinated, and the position of the material strip can be controlled more accurately, thereby improving the dimensional accuracy and production efficiency of the conductive sheet 4 and reducing material waste.

[0053] Through the setting of the pressing pieces 32, when the upper mold 21 moves from top to bottom, the two pressing pieces 32 can press and hold the material strip, so that the material strip cannot move during the stamping process, thereby ensuring that the material strip remains stable in the mold 2, preventing the material strip from sliding during the stamping process, ensuring the accuracy of the stamping position, and reducing the dimensional error and elastic deformation caused by the movement of the material strip, thereby improving the accuracy and consistency of the conductive sheet 4.

[0054] Embodiment 2

[0055] This is to prevent the two feeding members 31 from pulling the material strip back during the process of returning to the initial position, thereby affecting the position accuracy of the material strip.

[0056] refer to Fig. 9 and Fig.10 A rotating groove 318 is provided on the side where the two feeding members 31 are close to each other, and a pressure roller 319 is rotatably connected in the two rotating grooves 318. Both ends of the two pressure rollers 319 are fixedly connected with ratchets 320. Two sliding grooves 321 corresponding to the positions of the corresponding ratchet wheels 320 are provided inside the two rotating grooves 318. A ratchet pawl 322 capable of cooperating with the corresponding ratchet wheel 320 is slidably connected inside each sliding groove 321, and an elastic member 323 is connected between the end of each ratchet pawl 322 away from the ratchet wheel 320 and the corresponding sliding groove 321.

[0057] When the two feeding members 31 clamp the material belt and move toward the feeding direction, the two pressing rollers 319 cannot rotate due to the limiting action of the corresponding ratchet 320 and pawl 322. When the two feeding members 31 move away from the feeding direction, the pawl 322 corresponding to the two pressing rollers 319 no longer limits the ratchet 320.

[0058] During actual stamping work, when the upper mold 21 moves from bottom to top, making the two feeding pieces 31 gradually approach each other, the two pressure rollers 319 can clamp the material belt. When the two feeding pieces 31 drive the two pressure rollers 319 to move along the feeding direction of the material belt, the two pressure rollers 319 will be unable to rotate due to the limiting action of the corresponding ratchet wheels 320 and pawls 322. At this time, the two non-rotatable pressure rollers 319 can clamp the material belt and follow the corresponding two feeding pieces 31 to clamp and feed.

[0059] When the upper mold 21 moves downward and the two feeding members 31 gradually return to their initial positions, the ratchet pawls 322 corresponding to the two pressing rollers 319 no longer limit the ratchet wheel 320, and the two pressing rollers 319 can rotate normally without pulling the material strip back.
