[0031] Example 1

[0032] Please refer to 1, a riveting processing system for riveting cylindrical battery poles, including a conveying mechanism 100, a stamping mechanism 200 and a supporting mechanism 300, the conveying mechanism 100 includes a conveying line and a workpiece carrier 110, the workpiece carrier 110 is at least used to carry the workpiece to be riveted, the conveying line is used to convey the workpiece carrier 110, the stamping mechanism 200 and the supporting mechanism 300 are arranged at the riveting processing station, the stamping mechanism 200 is used to perform stamping and riveting processing on the workpiece conveyed to the riveting processing station, and the supporting mechanism 300 is used to withstand / buffer the pressure applied by the stamping mechanism 200 (or called riveting force) so that the main part of the workpiece carrier 110 is not subjected to the pressure of the stamping mechanism 200.

[0033] In this embodiment, the conveyor line runs along the first track. The conveyor line can be a chain conveyor mechanism 100, a conveyor belt or a track conveyor mechanism 100, etc. As long as it can drive the workpiece carrier 110 to transfer, there is no excessive restriction on its specific structure. It can be understood that the conveyor mechanism 100 can include multiple workpiece carriers 110, and multiple workpiece carriers 110 are arranged at intervals on the conveyor line and are sequentially conveyed to the riveting processing station. Exemplarily, the workpiece carrier 110 can be understood as a loading trolley.

[0034] In this embodiment, the conveyor line runs along a first track, the workpiece carrier 110 is transmission-connected to the conveyor line, and the workpiece carrier 110 can run along a second track driven by the conveyor line. The first track and the second track are spaced apart along a first direction, and the second direction is arranged to intersect with the first direction. The stamping mechanism 200 and the support mechanism 300 are arranged at a riveting processing station, and the riveting processing station is located on the second track.

[0035] In this embodiment, the workpiece carrier 110 is not directly disposed on the conveyor line, but is disposed on one side of the conveyor line and moves along a second track driven / driven by the conveyor line, and the second track and the first track are spaced apart along the first direction.

[0036] In this embodiment, the workpiece carrier 110 includes a mandrel floating plate 111, a riveting mandrel 114 and a carrier mounting plate 112, the mandrel floating plate 111 and the carrier mounting plate 112 are fixedly connected, the carrier mounting plate 112 is connected to the conveyor line, the riveting mandrel 114 is arranged on the mandrel floating plate 111, the mandrel floating plate 111 is provided with an escape hole, the bottom end of the riveting mandrel 114 extends out from the escape hole, wherein the riveting mandrel 114 is used to carry the workpiece to be riveted, and the workpiece is arranged at the top of the riveting mandrel 114. It should be noted that the carrier mounting plate 112 can be fixedly connected to the chain of the chain conveyor line, or connected to the conveyor belt, or fixedly connected to the slider on the track conveying mechanism 100.

[0037] In this embodiment, the support mechanism 300 and the stamping mechanism 200 are arranged relative to each other along the second direction. When the workpiece carrier 110 moves to the riveting processing station, the workpiece carrier 110 is located between the support mechanism 300 and the stamping mechanism 200 along the second direction. The support mechanism 300 is in contact with the workpiece carrier 110. When the stamping mechanism 200 performs stamping processing on the workpiece located on the workpiece carrier 110, the support mechanism 300 provides a supporting force to the workpiece carrier 110 in the opposite direction to the pressure applied by the stamping process.

[0038] In this embodiment, the support mechanism 300 includes a fixed riveting table 310 and a retractable force unloading mechanism 320. The force unloading mechanism 320 is arranged on one side of the riveting table 310. The top surface of the force unloading mechanism 320 is located above the top surface of the riveting table 310 along the second direction. When the workpiece carrier 110 moves above the support structure, the workpiece carrier 110 will first contact the force unloading mechanism 320 and generate a force.

[0039] Specifically, when the workpiece carrier 110 is located above the force unloading mechanism 320 along the second direction and the stamping mechanism 200 does not stamp the workpiece, the workpiece carrier 110 contacts the force unloading mechanism 320, and the workpiece carrier 110 is lifted up along the second direction by the force unloading mechanism 320 without contacting the riveting table 310. It can be understood that at this time, the force unloading mechanism 320 as a whole is still stretched upward along the second direction; and when the workpiece carrier 110 is located above the force unloading mechanism 320 along the second direction and the stamping mechanism 200 stamps the workpiece, the force unloading mechanism 320 is compressed along the second direction, and the workpiece carrier 110 contacts the riveting table 310. At this time, the top surface of the force unloading mechanism 320 is flush with or lower than the top surface of the riveting table 310, and the riveting table 310 rigidly bears the pressure / riveting force indirectly from the stamping mechanism 200.

[0040] In this embodiment, the riveting mandrel 114 includes a first part and a second part sequentially arranged along its own axial direction, the first part is arranged on a side of the second part close to the stamping mechanism 200, the first part can be understood as the top part, the second part is arranged on a side close to the support mechanism 300, the second part can be understood as the bottom part, the diameter of the first part is larger than the diameter of the second part, the aperture of the avoidance hole is larger than the diameter of the second part and smaller than the diameter of the first part, so that when the support mechanism 300 applies an upward force to the mandrel floating plate 111 When force is applied, the riveting mandrel 114 can be separated from the riveting table 310 when the mandrel floating plate 111 is pushed upward. When the stamping mechanism 200 stamps the workpiece on the riveting mandrel 114, the pressure applied by the stamping mechanism 200 is mainly concentrated on the riveting mandrel 114 and the riveting table 310, and the force applied to the mandrel floating plate 111 is relieved by the deformation of the unloading mechanism 320. It can be understood that the riveting mandrel 114 and the mandrel floating plate 111 can produce a certain relative movement along the avoidance hole.

[0041] In this embodiment, the unloading mechanism 320 includes a first elastic mechanism 321 that can undergo restorable deformation along the second direction, and the maximum elastic force provided by the first elastic mechanism 321 is greater than the total gravity of the workpiece carrier 110 and the workpiece, and the maximum elastic force provided by the first elastic mechanism 321 is less than the sum of the gravity of the workpiece carrier 110, the gravity of the workpiece and the maximum pressure applied by the stamping mechanism 200 to the workpiece to complete the stamping process. Exemplarily, the first elastic mechanism 321 can be a spring, etc.

[0042] In this embodiment, the unloading mechanism 320 also includes a rotatable follower guide mechanism 323, which is arranged on the top of the first elastic mechanism 321 along the second direction, and the top surface of the follower guide mechanism 323 is located above the top surface of the riveting table 310; when the follower guide mechanism 323 contacts the workpiece carrier 110, the follower guide mechanism 323 can rotate under the friction of the workpiece carrier 110, and the workpiece carrier 110 moves along the follower guide mechanism 323 to the top of the unloading mechanism 320. Exemplarily, the follower guide mechanism 323 can be a rolling body such as a follower bearing, the inner ring of the follower bearing is fixedly connected to the first elastic mechanism 321, and the outer ring of the follower bearing can rotate. On the one hand, the follower guide mechanism 323 can play a guiding role to move the workpiece carrier 110 to the top of the support mechanism 300. On the other hand, by making the follower guide mechanism 323 roll, the static friction force when the follower guide mechanism 323 and the workpiece carrier 110 are in contact can be converted into dynamic friction force, thereby reducing the movement resistance.

[0043] In this embodiment, corresponding to the follow-up guide mechanism 323, a contact block 113 is also provided at the bottom of the core rod floating plate 111, and the bottom end surface of the contact block 113 is lower than the bottom end surface of the riveting core rod 114 along the second direction. When the workpiece carrier 110 moves to the riveting processing station, it will first contact the follow-up guide mechanism 323.

[0044] It should be noted that the follower guide mechanism 323 can be installed on the mounting block 322, and the mounting block 322 is fixed on the top of the first elastic mechanism 321; of course, the support mechanism 300 can also include a fixed base 330, and the riveting platform 310 and the force unloading mechanism 320 are both installed on the base 330.

[0045] In this embodiment, the support mechanism 300 may further include a plurality of the unloading mechanisms 320, and the plurality of the unloading mechanisms are combined to form two unloading mechanism groups. The two unloading mechanism groups are preferably symmetrically arranged on both sides of the riveting table 310. It can be understood that the number of unloading mechanisms contained in the two unloading mechanism groups is preferably the same.

[0046] In this embodiment, the stamping mechanism 200 includes a stamping power mechanism, an upper template 220 and a riveted upper mold 230. The riveted upper mold 230 is fixedly arranged on the upper template 220. The upper template 220 is transmission-connected to the stamping power mechanism. The riveted upper mold 230 can move along the second direction and contact the workpiece under the drive of the stamping power mechanism. The stamping power mechanism, the upper template 220 and the riveted upper mold 230 are all known to those skilled in the art and are not specifically limited here.

[0047] In this embodiment, a riveting system for riveting cylindrical battery poles performs riveting on battery poles in a working process that at least includes:

[0048] Before the stamping process is performed, the upper template 220 of the stamping mechanism 200 is at the maximum position of the closed height, that is, the upper template 220 is at the highest position;

[0049] The multiple workpiece carriers 110 in the conveying mechanism 100 move along the conveying line, and the workpiece carriers 110 move from a first position to a second position, and then to a third position, wherein the second position is a riveting processing station / position;

[0050] When the workpiece carrier 110 moves from the first position to the second position, the first elastic mechanism 321 is in an uncompressed state (i.e., a naturally relaxed state), and the follower guide mechanism 323 first contacts the contact block 113 at the bottom of the mandrel floating plate 111, thereby causing the mandrel floating plate 111 to be lifted upward by the first elastic mechanism 321, and then causing the riveting mandrel 114 to be lifted upward. At this time, the bottom end surface of the riveting mandrel 114 is separated from the surface of the riveting table 310 until the workpiece carrier 110 is completely located in the second position.

[0051] When the workpiece carrier 110 is completely located at the second position, the stamping mechanism 200 is started, the upper template 220 starts to move downward, and the riveting upper die 230 also moves downward, and gradually contacts the riveting mandrel 114 and forces the riveting mandrel 114 to move downward. When the contact is completed, the riveting mandrel 114 continues to move downward, and the lower surface of the riveting mandrel 114 contacts the table surface of the riveting table 310; as the upper template 220 continues to move downward, the gap between the lower surface of the riveting upper die 230 and the upper surface of the riveting mandrel 114 is further reduced to the size of the pole after riveting, thereby completing the riveting of the battery pole.

[0052] During the above riveting process, the riveting mandrel 114 will drive the mandrel floating plate 111 to move downward, thereby causing the contact block 113 to move downward, and then causing the first elastic mechanism 321 to be in a compressed state; when the riveting of the battery pole is completed, the workpiece carrier 110 moves from the second position to the third position; during this process, the stamping mechanism 200 runs in the opposite direction, the upper template 220 starts to move upward, and the riveting upper mold 230 also moves upward accordingly, and the riveting mandrel 114 starts to drive the contact block 113 and the mandrel floating plate 111 to move upward under the action of the first elastic mechanism 321, and finally the lower surface of the riveting mandrel 114 leaves the riveting table 310; during the process of the workpiece carrier 110 moving from the second position to the third position, the riveting mandrel 114 is disengaged from the riveting table 310.

[0053] Example 1

[0054] Please refer to 4. A riveting processing system for riveting cylindrical battery poles in this embodiment is basically the same as that in embodiment 1. The same parts of the two are not repeated here. The main difference between the two is:

[0055] The riveting processing system for riveting cylindrical battery poles in this embodiment also includes a stamping guide structure, which includes a positioning column 420 and a positioning sleeve 410. The positioning column is fixedly arranged on the upper template 220, and the positioning sleeve is fixedly arranged on the core rod floating plate 111. The positioning column and the positioning sleeve are relatively arranged along the second direction. When the riveting upper mold 230 approaches the workpiece on the workpiece carrier 110 along the second direction, one end of the positioning column can be inserted into the positioning sleeve accordingly.

[0056] In this embodiment, the positioning column 420 includes a first positioning column and a second elastic mechanism, one end of the second elastic mechanism is fixedly matched with the upper template 220, and the other end is fixedly connected to the first positioning column. Of course, the positioning column can also include a second positioning column, and the second positioning column is connected to the first positioning column via the second elastic mechanism. When the positioning column is subjected to pressure applied along the second direction, the first positioning column and the second positioning column can generate relative movement along the second direction. Exemplarily, the second elastic mechanism can also be a spring, etc.

[0057] The utility model provides a riveting processing system for riveting cylindrical battery poles, so that the workpiece carrier does not directly contact the riveting table when on the riveting table, and only contacts during riveting, and when in contact, the moving part of the workpiece carrier connected to the conveyor line will not be subjected to the riveting force, thereby avoiding the problem of damaging the workpiece carrier during the riveting process. In addition, the utility model provides a riveting processing system for riveting cylindrical battery poles, which does not require the workpiece carrier to bear the riveting force when no riveting processing action occurs, thereby optimizing the force condition of the workpiece carrier and reducing the design and manufacturing costs of the workpiece carrier.
