Description

Technical Field

[0001] The present application relates to the technical field of manufacturing battery poles, and in particular to a method and device for manufacturing battery poles. Background Art

[0002] The battery pole is a key component that connects the internal electrode of the battery with the external circuit. It not only carries the task of current transmission, but also affects the sealing, reliability and safety of the battery. Traditionally, battery poles are mostly made of metal materials, such as lead, aluminum or copper, which have good conductivity and mechanical strength. However, there are many challenges in the production process: on the one hand, the pole needs to adapt to complex geometric shapes to match different battery designs, which increases the difficulty of molding; on the other hand, in order to ensure good conductive contact, the pole surface must be smooth and defect-free, which places strict requirements on processing accuracy. Therefore, each step of the traditional manufacturing process may introduce variability, thereby affecting the quality of the final product.

[0003] In order to solve the above-mentioned problems, the casting process has begun to be widely used in the prior art to make battery poles. Casting is a method of forming a specific shape by injecting molten metal into a mold. It can complete the molding of complex structures in one go, greatly simplifying the production process and reducing the cumulative errors caused by multiple processes. Especially for poles that require highly customized designs, the casting process can more flexibly meet the needs of different specifications. At the same time, advanced casting techniques (such as low-pressure casting and pressure casting) can also control the cooling rate and solidification process, making the internal structure of the casting denser and the surface quality better, thereby improving the mechanical strength and conductivity of the pole and enhancing the reliability of the product.

[0004] Although the casting process has greatly improved the manufacturing of battery poles, there are still some problems that need to be solved in practical applications. The first is the problem of yield rate. Since defects such as pores and cracks will inevitably appear during the casting process, these defects will directly affect the quality of the pole, reduce its electrical performance and mechanical strength, and lead to a high defective rate. Secondly, with the growth of market demand for batteries, the existing casting production lines are facing the pressure of insufficient production capacity. Traditional casting equipment and technology are difficult to respond quickly to changes in market demand and cannot achieve efficient large-scale production. Therefore, how to improve the yield rate and expand production capacity through manufacturing processes or improved manufacturing equipment has become a technical problem that urgently needs to be solved. Summary of the invention

[0005] The embodiment of the present application provides a method and device for manufacturing a battery pole to solve the technical problems of low yield and insufficient production capacity in the current manufacturing of battery poles. The technical solution is as follows:

[0006] In a first aspect, an embodiment of the present application provides a method for manufacturing a battery pole, comprising:

[0007] The blank is transported to the feeding carrier on the stamping die by the conveying mechanism;

[0008] When the stamping die enters the mold closing state, a stamping operation is performed on the blank material on the feeding carrier corresponding to the target station in the stamping die;

[0009] When the stamping die is turned to the open state, the feed carrier transfers the stamped blank to the next target station, and repeats the stamping action of the stamping die and the transfer action of the feed carrier until the blank is made into a pole product.

[0010] In one embodiment, when the stamping die enters the mold closing state, the step of performing a stamping operation on the blank corresponding to the target station in the stamping die on the feeding carrier further includes:

[0011] When the stamping die enters the mold closing state, the blank is pressed into the clamping hole of the feeding carrier at the first stamping station among the target stations;

[0012] When the stamping die enters the mold closing state, further stamping operations are also performed on the blanks on the remaining stamping stations in the target station.

[0013] In one embodiment, when the stamping die enters the mold closing state, the step of performing further stamping operations on the blanks at the remaining stamping stations in the target station also includes:

[0014] The blank material located at the second stamping station in the target station is subjected to a stamping forming process by a stamping die;

[0015] The blank material located at the third stamping station in the target station is subjected to a stamping-type punching process by a stamping die;

[0016] The blank material located at the fourth stamping station among the target stations is subjected to a stamping and knurling process by the stamping die;

[0017] The blank material located at the fifth stamping station among the target stations is subjected to a stamping blanking process through a stamping die.

[0018] In one embodiment, when the stamping die is opened, the feeding carrier transfers the stamped blank to the next target station, and repeats the above stamping and transfer steps until the blank is made into a pole product. The step includes:

[0019] The positioning pins on the stamping die are respectively inserted into or out of the positioning holes on the feeding carrier, and the positioning holes are arranged equidistantly along the first direction, so that the distance moved by the feeding carrier each time is the spacing distance between adjacent positioning holes.

[0020] In one embodiment, the step of conveying the blank to the feeding carrier on the stamping die by the conveying mechanism includes:

[0021] The conveying unit in the conveying mechanism is used to sequentially convey the blanks to the position to be pushed;

[0022] When the stamping die is turned to the open state, the blank in the waiting position is pushed to the clamping hole of the feeding carrier through the pushing unit in the conveying mechanism. At this time, the blank corresponds to the first stamping station in the target station.

[0023] In a second aspect, an embodiment of the present application provides a device for manufacturing a battery pole, comprising: a movable module, which has punches arranged in parallel along a first direction, and is used to punch a blank; a fixed module, which has a target station corresponding to each punch, and is used to cooperate with the corresponding punch to complete the punching operation; and a feeding carrier, which is movably configured on the fixed module, and the feeding carrier covers each target station and is used to carry the blank;

[0024] When the moving module is away from the fixed module and is in a mold opening state, the feeding carrier completes an equidistant movement along the first direction to sequentially transfer the blank on the feeding carrier to each target station.

[0025] In one embodiment, it also includes: a first track, which is arranged on a fixed module, and the discharge port of the first track is directly opposite to the first stamping station in the target station; a second track, which is connected to the feed port of the first track, and a push position is formed at the connection between the first track and the second track; and a pushing component, which has a piston rod corresponding to the push position, so that under the drive of the pushing component, the blank located at the push position passes through the first track to reach the first stamping station.

[0026] In one embodiment, it further includes: a vibration component, which is arranged on the second track and is used to provide the second track with a vibration force that drives the blank to move.

[0027] In one embodiment, the feeding carrier is provided with clamping holes arranged equidistantly along the first direction, the aperture of the clamping holes is smaller than the size of the blank, and the blank is fastened in the clamping holes through stamping by the moving module.

[0029] Compared with the prior art, the method and device for making battery poles proposed in the above technical solution adopt a stamping die with a progressive feeding mode, which significantly improves the manufacturing process of battery poles. By introducing a continuous stamping process, the inefficient mode of traditional multiple independent processes is abandoned. By combining the stamping die with the progressive feeding mode, it is possible to complete different stamping processes for multiple blanks in one stamping operation, thereby greatly shortening the overall processing time and improving the overall production speed. The equidistant transfer mechanism of the feeding carrier ensures the position accuracy of each battery pole during the processing process, reducing product defects caused by position deviation. This stable processing environment helps to maintain the consistency of product quality and reduce errors caused by human factors or equipment fluctuations. After the improvement, the stamping process not only simplifies the production process, but also reduces the probability of unqualified products by controlling the feeding accuracy, significantly improving the yield rate of the final product. The present invention is particularly suitable for mass production occasions and can meet the market's growing demand for high-efficiency battery poles. With the development of the global new energy industry, the demand for high-performance batteries and their components continues to rise. The efficient production method provided by the present invention can better respond to changes in market demand.

[0030] In summary, the present application provides an efficient, stable and high-quality battery pole manufacturing solution, which not only solves the problems of insufficient production capacity and low yield rate in traditional casting processes, but also provides a new solution for large-scale production and cost control in the industry.

[0046] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0047] In the first embodiment of the present application, a method for manufacturing a battery pole is proposed, and the method may include the following steps:

[0048] The blank is transported to the feeding carrier 2 on the stamping die by the conveying mechanism;

[0049] When the stamping die enters the mold closing state, a stamping operation is performed on the blank corresponding to the target station in the stamping die on the feeding carrier 2;

[0050] When the stamping die is turned to the open state, the feed carrier 2 transfers the stamped blank to the next target station, and repeats the stamping action of the stamping die and the transfer action of the feed carrier until the blank is made into a pole product.

[0051] Specifically, in the technical solution adopted in the present application, in some embodiments, the blank can be transported to the feeding carrier 2 on the stamping die through a conveying mechanism, and the feeding carrier 2 is used to move the blank to each target station on the stamping die, so that when the stamping die enters the mold closing state, the blank located at the target station is stamped and formed by the stamping die. The technical key point of the present application is that when the stamping die is converted from the mold closing state to the mold opening state, the feeding carrier 2 gradually moves the blank corresponding to the current target station to the next target station. It can be understood that after the stamping die completes the stamping operation on the blank at the current target station, in the mold opening state of the stamping die, the blank that has completed the stamping operation of the second stamping station 12 moves toward the third stamping station 13 through the feeding carrier 2 until it reaches the third stamping station 13 and completes the corresponding stamping process through the stamping die, and the blank that has completed the stamping operation of the first stamping station 11 moves toward the second stamping station 12 through the feeding carrier 2 until it reaches the second stamping station 12 and completes the corresponding stamping process through the stamping die. After continuously repeating the stamping and transfer steps, the blank can be processed into a qualified pole product. This method utilizes the stability of the stamping process and improves the yield rate of the pole product. At the same time, the blank is delivered to the next target workstation through the gap when the stamping die is in the open state by the feeding carrier 2, which effectively improves the efficiency of manufacturing battery poles and significantly improves the production capacity compared with the current traditional process of manufacturing battery poles.

[0052] It should be explained that in this method, the transfer and stamping operations need to be repeated continuously. In the gap between each time when the stamping die is in the mold opening state, the blank is transferred to the feeding carrier 2 through the conveying mechanism, and the blank that has completed the initial stamping process is gradually transferred to the next target station through the movement of the feeding carrier 2. It should be noted that in the early stage of making battery poles using this method, the above steps need to be repeated many times before the continuity of the stamping process in this method can be truly reflected.

[0053] Furthermore, in some embodiments, when the stamping die enters the mold closing state, the step of performing a stamping operation on the blank corresponding to the target station in the stamping die on the feeding carrier 2 further includes:

[0054] When the stamping die enters the mold closing state, the blank is pressed into the clamping hole 21 of the feeding carrier 2 at the first stamping station 11 in the target station;

[0055] When the stamping die enters the mold closing state, further stamping operations are also performed on the blanks on the remaining stamping stations in the target station.

[0056] Specifically, in the technical solution adopted in the present application, in some embodiments, when the blank enters the feeding carrier 2 through the transfer of the conveying mechanism, the blank is located above the clamping hole 21 on the feeding carrier 2, and corresponds to the first stamping station 11 on the stamping die. When the stamping die enters the mold closing state, the punch of the stamping die presses the blank into the clamping hole 21 on the feeding carrier 2 and fixes it. In this embodiment, the size of the blank is larger than the aperture of the clamping hole 21, so that after the blank is pressed into the clamping hole 21 by the punch, it can effectively avoid the offset of the blank in the subsequent stamping process to affect the yield rate of the battery pole. In an embodiment of the present application, the stamping die has multiple punches and target stations corresponding to each punch. Therefore, while the blank that first enters the feeding carrier 2 is pressed into the clamping hole 21 by the stamping die, the stamping die also performs further stamping processes on the blanks on the remaining target stations, that is: each time the stamping die is closed, the blanks on all the target stations are stamped at the same time, thereby ensuring the efficiency of the manufacturing process.

[0057] Furthermore, in some embodiments, when the stamping die enters the mold closing state, the step of performing further stamping operations on the blanks at the remaining stamping stations in the target station also includes:

[0058] The blank material located at the second stamping station 12 in the target station is subjected to a stamping forming process by a stamping die;

[0059] The blank material located at the third stamping station 13 in the target station is subjected to a stamping-type punching process by a stamping die;

[0060] The blank material located at the fourth stamping station 14 in the target station is subjected to a stamping and knurling process by the stamping die;

[0061] The blank material located at the fifth punching station 15 among the target stations is subjected to a punching blanking process by a punching die.

[0062] Specifically, in the technical solution adopted in the present application, in some embodiments, the stamping tools on the stamping die may include: a forming process, a punching process and a blanking process. Specifically, the blank with the fixed hole 21 can be gradually transferred to the second stamping station 12 of the stamping die through the movement of the feeding carrier 2. When the blank reaches the second stamping station 12, the stamping die can be closed to perform a stamping forming process on the blank; at the same time, the blank that has completed the forming process is gradually transferred to the third stamping station 13 of the stamping die through the movement of the feeding carrier 2. When the blank reaches the third stamping station 13, the stamping die can be closed to perform a stamping cutting process on the blank; in the same time period, the blank that has completed the cutting process can also be gradually transferred to the fourth stamping station 14 of the stamping die through the movement of the feeding carrier 2. When the blank reaches the fourth stamping station 14, the stamping mold can be closed to perform a stamping knurling process on the blank to form a knurling structure 100 on the blank. The knurling structure 100 can refer to Figure 2 As shown. When the blank reaches the fifth stamping station 15, the stamping die is closed to perform a stamping blanking process on the blank; by continuously repeating the stamping and transfer steps, it can be quickly stamped into a qualified pole product. It should be noted that the stamping process in this embodiment is not limited to the above three types, and other stamping processes can be added. The steps are the same as the above stamping process, so they are not repeated and are all within the protection scope of this application.

[0063] Further, in some embodiments, when the stamping die is opened, the feeding carrier 2 transfers the stamped blank to the next target station, and repeats the above stamping and transfer steps until the blank is made into a pole product. The steps include:

[0064] The positioning pins on the stamping die are respectively inserted into or out of the positioning holes 22 on the feeding carrier 2 , and the positioning holes 22 are equidistantly arranged along the first direction, so that the distance that the feeding carrier 2 moves each time is the spacing distance between adjacent positioning holes 22 .

[0065] Specifically, in the technical solution adopted by the present application, in some embodiments, the distance that the feed carrier 2 moves each time can be limited by the positioning pin on the stamping die. Specifically, when the feed carrier 2 needs to move, the positioning pin retracts through its own telescopic function, thereby moving out of the current positioning hole 22 on the feed carrier 2, so that the feed carrier 2 can move in the first direction, and when the positioning pin is opposite to the next positioning hole 22, the positioning pin extends through its own telescopic function, thereby penetrating into the positioning hole 22 on the feed carrier 2, so as to limit the feed carrier 2 from continuing to move in the first direction. Since in this embodiment, the positioning holes 22 are evenly arranged on the feeding carrier 2 along the first direction, so that the feeding carrier 2 moves the same distance each time under the restriction of the positioning pin, that is, equidistant movement; it can be explained that, with reference to the above embodiment, there are multiple punches on the stamping die, so that different stamping processes can be carried out simultaneously in the mold closing state, and the spacing distance between two adjacent punches can be set to be the same as the equidistant movement distance of the feeding carrier 2 each time, or a multiple of the equidistant movement distance of the feeding carrier 2 each time, so that the feeding carrier 2 can move the blank of the previous target station to the next target station after one or more equidistant movements, for example: transferring the blank on the first stamping station 11 to the second stamping station 12.

[0066] Furthermore, in some embodiments, the step of conveying the blank to the feeding carrier 2 on the stamping die by the conveying mechanism includes:

[0067] The conveying unit in the conveying mechanism is used to sequentially convey the blanks to the position to be pushed 5;

[0068] When the stamping die is turned to the open state, the blank in the waiting position 5 is pushed to the clamping hole 21 of the feeding carrier 2 by the pushing unit in the conveying mechanism. At this time, the blank corresponds to the first stamping station 11 in the target station.

[0069] Specifically, in the technical solution adopted in the present application, in some embodiments, in order to be able to stably move the blank to the feeding carrier 2 during the mold opening process of the stamping die, and accurately place it on the first stamping station 11 on the stamping die. First, the conveying unit in the conveying mechanism can be used to convey the blanks to the waiting pushing position 5 in sequence. The waiting pushing position 5 is set to store one blank, and the remaining blanks are lined up in a row, waiting to enter the waiting pushing position 5. In this embodiment, the conveying unit can use a vibration disk 8 and a vibration track connected to the vibration disk 8 to be able to stably and orderly convey the blanks to the waiting pushing position 5; when the stamping die is changed from the mold closing state to the mold opening state, the blank located at the waiting pushing position 5 can be pushed to the clamping hole 21 of the feeding carrier 2 by the pushing unit, and corresponds to the first stamping station 11 on the stamping die. In this embodiment, the pushing unit can use a pushing cylinder and a pushing track, the pushing track is connected to the vibration track, and the waiting pushing position 5 is formed at the connection between the pushing track and the vibration track, and the piston rod of the pushing cylinder passes through the pushing track during the process of opening the stamping die to push the blank out of the pushing track. It should be explained that the outlet of the pushing track is opposite to the first stamping station 11.

[0070] Reference Figure 1 As shown, in the second embodiment of the present application, a device for manufacturing a battery pole is proposed, and the device may include: a movable module, which has punches arranged in parallel along a first direction, and is used for punching a blank; a fixed module 1, which has a target station corresponding to each punch, and is used to cooperate with the corresponding punch to complete the punching operation; and a feeding carrier 2, which is movably configured on the fixed module 1, and the feeding carrier 2 covers each target station and is used to carry the blank;

[0071] When the movable module is away from the fixed module 1 and is in the mold opening state, the feeding carrier 2 completes an equidistant movement along the first direction to transfer the blank on the feeding carrier 2 to each target station in sequence.

[0072] Specifically, in the technical solution adopted in the present application, in some embodiments, the device includes a stamping die, and the stamping die can include: a moving module and a fixed module 1, the moving module is pressed down in the direction of the fixed module 1 to form a stamping operation, and different stamping processes use different punches and / or different structures of the concave mold on the fixed module 1. In this embodiment, the moving module has punches arranged in parallel along the first direction, which are used to stamp the blank on the fixed module 1, and the fixed module 1 has a plurality of target stations formed by dies of different structures, and each target station corresponds to each punch one by one to cooperate with the corresponding stamping operation of the blank on the different target stations. The technical key point of the present application is that a feeding carrier 2 is provided on the fixed module 1, and the feeding carrier 2 can be moved along the first direction on the fixed module 1 by the traction of the traction component or by the driving of the driving component, and the feeding carrier 2 covers the top of each target station, which is used to carry the blank and drive the blank to move synchronously with it.

[0073] In one embodiment, each punch and each target station are arranged in a line along the first direction, and the feed carrier 2 is set to a straight strip structure to achieve coverage on all target stations. When in use, when the stamping die is changed from the mold closing state to the mold opening state, that is: the moving module is away from the fixed module 1, then the feed carrier 2 completes an equidistant movement along the first direction on the fixed module 1 until the blank on the feed carrier 2 is moved to the next target station, and when the stamping die is changed from the mold opening state to the mold closing state, that is: the moving module is pressed down in the direction of the fixed module 1, and the blank on the corresponding target station is punched by each punch, and the corresponding stamping process is determined by the concave die on the fixed module 1. The production of battery poles through the stamping process can effectively improve the product yield and production efficiency, and avoid the situation where the product is in short supply due to insufficient production capacity.

[0074] Reference Figure 1 and Figure 2As shown, in some embodiments, the fixed module 1 has several target stations. In this embodiment, four target stations are taken as an example. The fixed module 1 is arranged with a second stamping station 12, a third stamping station 13, a fourth stamping station 14, a fifth stamping station 15 and the first stamping station 11 mentioned above; wherein the first stamping station 11 can be used as a pre-treatment station before the stamping process, specifically for pressing the blank into the clamping structure on the feeding carrier 2 for fixing; the second stamping station 12 can be the next target station of the first stamping station 11, and can be used as the first stamping process, such as: forming process; the third stamping station 13 can be the second stamping process The next target station of the third stamping station 12 can be used as the second stamping process, for example: a punching process; the fourth stamping station can be the next target station of the third stamping station 13, which can be used as the third stamping process, for example: a stamping knurling process, specifically, stamping a knurling structure 100 on the blank; and at the end of the stamping operation is the fifth stamping station 15, which can be the next target station of the fourth stamping station 14, which can be used as the fourth stamping process, and can be understood as the last stamping process of the stamping process, for example: a blanking process. It should be noted that the device for making battery poles proposed in the present application may also include other target stations to achieve stamping processes different from those mentioned above, all of which are within the protection scope of the present application.

[0075] Further, see Figure 1 As shown, in some embodiments, it also includes: a first track 3, which is arranged on the fixed module 1, and the discharge port of the first track 3 is directly opposite to the first stamping station 11 in the target station; a second track 4, which is connected to the feed port of the first track 3, and a push position 5 is provided at the connection between the first track 3 and the second track 4; and a pushing component 7, which has a piston rod corresponding to the push position 5, so that under the drive of the pushing component 7, the blank located at the push position 5 passes through the first track 3 to reach the first stamping station 11.

[0076] Specifically, in the technical solution adopted in the present application, in some embodiments, a first track 3 is further provided on the fixed module 1, and the discharge port of the first track 3 is directly opposite to the first stamping station 11, and the first stamping station 11 is the target station where the blank is first transferred to the feeding carrier 2. The feed port of the first track 3 is connected to the second track 4, and the second track 4 is used to transport the blank to the feed port of the first track 3. In this embodiment, a waiting position 5 is formed between the first track 3 and the second track 4, and the waiting position 5 can be formed by the first track 3 and the second track 4 extending in different directions, for example: the first track 3 can extend in a second direction perpendicular to the feeding direction, and the second track 4 can extend in a first direction, and the first direction is the feeding direction, so that a waiting position 5 for storing a blank can be formed at the junction of the first track 3 and the second track 4. In this embodiment, a pushing component 7 is further provided, and the pushing component 7 has a piston rod that can correspond to the position to be pushed 5, and the pushing direction of the piston rod is the second direction, and the head of the piston rod, the position to be pushed 5 and the first stamping station 11 are guided into a straight line by the first track 3, so that the pushing component 7 can push the blank located at the position to be pushed 5 to the part of the feeding carrier 2 corresponding to the first stamping station 11 by extending the piston rod. In this way, the blank can be accurately transferred to the first stamping station 11, avoiding the high probability of inadequate transfer during the moving process.

[0077] In one embodiment, the mechanism for storing the blanks may adopt a vibration plate 8, specifically, the blanks are stored in the cavity of the vibration plate 8, and the blanks are discharged by the vibration force and rotation force of the vibration plate 8, and the second track 4 is connected to the discharge port of the vibration plate 8, so as to convey the blanks discharged from the vibration plate 8 to the to-be-pushed position 5 through the second track 4. It should be explained that in the present application, the conveying mechanism for transferring the blanks to the first stamping station 11 in the target station may include: a vibration plate 8, a first track 3, a second track 4, a vibration component 6, and a pushing component 7.

[0078] Further, see Figure 1 As shown, in some embodiments, it also includes: a vibration component 6, which is arranged on the second track 4 and is used to make the second track 4 have a vibration force that drives the blank to move.

[0079] Specifically, in the technical solution adopted by the present application, in one embodiment, the blank can be driven to move on the second track 4 by the vibration force. Therefore, a vibration component 6 is arranged on the second track 4, and the vibration component 6 has a self-vibration function and transmits the vibration force to the blank through the second track 4, so that the blank moves on the second track 4 by the vibration force. In this embodiment, the vibration component 6 can be a vibrator, such as an electromagnetic vibrator or a piezoelectric vibrator.

[0080] Further, see Figure 1 As shown, in some embodiments, the feeding carrier 2 is provided with clamping holes 21 arranged equidistantly along the first direction, the aperture of the clamping holes 21 is smaller than the size of the blank, and the blank is fastened in the clamping holes 21 through stamping of the moving module.

[0081] Specifically, in the technical solution adopted in the present application, in some embodiments, a plurality of equally spaced clamping holes 21 are provided on the feeding carrier 2 for accommodating the blank, and each clamping hole 21 is arranged along a first direction, namely, the feeding direction. In order to enable the clamping hole 21 to be firmly clamped with the blank, the aperture of the clamping hole 21 can be set to be smaller than the size of the blank, and the blank is pressed into the clamping hole 21 at the first stamping station 11 by a stamping die to fix it, thereby effectively avoiding irregular displacement of the blank in the subsequent stamping process, and effectively improving the yield rate of the pole product after adopting this device.

[0082] Further, see Figure 1 As shown, in some embodiments, the feeding carrier 2 is further provided with a plurality of groups of positioning holes 22 arranged equidistantly along the first direction, and each group of positioning holes 22 is respectively located between two adjacent clamping holes 21; the fixed module 1 is provided with positioning pins corresponding to the positioning holes 22, and the positioning pins have a telescopic function that can be inserted into or moved out of the positioning holes 22, so as to limit the displacement distance of the feeding carrier 2 each time by inserting the positioning pins into the corresponding positioning holes 22.

[0083] Specifically, in the technical solution adopted in the present application, in some embodiments, a plurality of groups of positioning holes 22 are further provided on the feed carrier 2, each group of positioning holes 22 is arranged between two adjacent clamping holes 21 along the first direction, and the spacing between each group of positioning holes 22 is the same; and a positioning pin with a telescopic function is provided on the fixed module 1, which is used to penetrate and position to limit the movement of the feed carrier 2 along the first direction. In one embodiment, a double row of positioning holes 22 can be used on the feed carrier 2, that is, the number of each group of positioning holes 22 is two, and they are relatively arranged on both sides of the feed carrier 2. In this embodiment, a pushing component can be provided in the fixed module 1 to push the positioning pin to extend, and an elastic element supported between the positioning pin and the fixed module 1 by elastic force is used to drive the positioning pin to reset. Specifically, after the pushing component releases the pushing force on the positioning pin, the positioning pin is reset by the rebound force of the elastic element. It should be noted that the pushing component and the positioning pin are not shown in the accompanying drawings. During use, when the stamping die is in the open state, the positioning pins are driven by the pushing component and the elastic element to complete the operation of moving out of the current group of positioning holes 22 and entering the next group of positioning holes 22, thereby achieving the feeding carrier 2 being driven by the traction component or the driving component to complete an equidistant movement along the first direction on the fixed module 1.
