Description

Technical Field

[0001] This application relates to the field of cylindrical battery welding technology, and in particular to a clamping device and welding equipment. Background Technology

[0002] With the rapid development of new energy vehicles, reducing production costs has become a trend. Large cylindrical batteries, through the synergistic effect of innovative single-cell structure and optimized system integration, have effectively reduced battery manufacturing costs. Among them, the 4680 battery has become a focus of market attention since its launch.

[0003] Currently, the end caps and bodies of large cylindrical batteries are mostly welded using laser welding. During the welding process, rollers are placed above the body to press the body firmly, thereby reducing radial runout and ensuring welding quality.

[0004] In related technologies, in order to avoid the rollers above the cylinder colliding with the cylinder during the feeding process, the area through which the cylinder passes during the feeding process will be directly separated from the area where the rollers are located. The pressing device needs to occupy more space, resulting in low space utilization. Utility Model Content

[0022] According to some embodiments of this application, the second connecting seat is located on the side of the first connecting seat closer to the processing position, and the maximum distance between the first connecting seat and the second connecting seat can be adjusted.

[0023] According to some embodiments of this application, the buffer component further includes:

[0024] An adjusting screw is threaded into the first connecting seat, and one end of the adjusting screw can abut against the second connecting seat to limit the movement of the second connecting seat away from the first connecting seat;

[0025] Alternatively, the adjusting screw is threaded into the second connecting seat, and one end of the adjusting screw can abut against the first connecting seat to restrict the movement of the second connecting seat away from the first connecting seat.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0054] Reference Figure 1 and Figure 2 The clamping device according to a first aspect embodiment of this application includes a clamping member 110 and a drive module 200. The clamping member 110 is used to abut against the outer peripheral surface 411 of a product 410 in a processing position. The area traversed by the product 410 during its loading to the processing position is defined as a first region 120 (refer to...). Figure 2 ).

[0055] The drive module 200 includes an output terminal 230 (see reference). Figure 3 The clamping element 110 is mounted on the output end 230. The drive module 200 is used to drive the clamping element 110 into or out of the first region 120. The drive module 200 is also used to drive the clamping element 110 closer to the machining position so that the clamping element 110 abuts against the outer peripheral surface 411. The drive module 200 is also used to drive the clamping element 110 away from the machining position.

[0056] The clamping device according to the embodiments of this application has at least the following beneficial effects: the area through which the product 410 passes during the process of being fed to the processing position is the first area 120. Under the drive of the drive module 200, the clamping member 110 can enter the first area 120 to complete the clamping of the product 410. When it is necessary to feed the product, the clamping member 110 leaves the first area 120. Thus, the clamping member 110 can temporarily use the area where the product 410 is fed when working, and the clamping device occupies less extra space, thereby improving the space utilization rate.

[0057] Specifically, product 410 can be the body and end cap of a cylindrical battery, but is not limited to this. For example, product 410 can also be a connector, a cylindrical container, etc.

[0058] Specifically, in order to cooperate with the rotation of product 410, the clamping element 110 is usually a roller, but it is not limited to this. For example, the clamping element 110 can also be a pressure block, an arc-shaped rubber pad, etc.

[0059] Specifically, the drive module 200 includes a first drive assembly 210 and a second drive assembly 220. The first drive assembly 210 is used to drive the clamping member 110 into or out of the first region 120, and the second drive assembly 220 is used to drive the clamping member 110 closer to or away from the processing position. The second drive assembly 220 includes a base 221, on which the clamping member 110 is mounted (see below for specific mounting structure).

[0060] The first drive assembly 210 includes a first cylinder 211, a base 212, and a first sliding assembly 213. The first sliding assembly 213 includes a first slider and a first slide rail, which are slidably connected. The first slide rail is fixed to the base 212 by fasteners (bolts, studs, etc.), and the first slider is fixed to the base 221 by fasteners. The first cylinder body of the first cylinder 211 is fixed to the base 212, and the first piston rod of the first cylinder 211 is connected to the base 221 via a floating joint.

[0061] Therefore, when the first cylinder 211 is ventilated, it can drive the clamping member 110 into or out of the first area 120.

[0062] In another embodiment, the first drive assembly 210 may also be one of a linear motor, a hydraulic cylinder, an electric cylinder, a motor-driven rack and pinion mechanism, a motor-driven sprocket and chain mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven crank and slider mechanism.

[0063] In some embodiments of this application, the first region 120 also includes the region through which the product 410 passes during the unloading process from the processing location.

[0064] The first area 120 includes the unloading area of ​​product 410, thereby providing more space options for the clamping component 110 and greater flexibility for the clamping device.

[0065] In some embodiments of this application, the first region 120 includes the region directly above the product 410 in the processing position.

[0066] By utilizing the area directly above the product 410 in the processing position, the clamping member 110 can directly press down on the product 410 after entering the first area 120, thus increasing the working efficiency of the clamping device.

[0067] Reference Figure 2 According to some embodiments of this application, the axial direction of the product 410 in the processing position is defined as the first direction (refer to...). Figure 2 (For example, the first direction is the front-to-back direction), the drive module 200 is used to drive the clamping member 110 to enter or leave the first region 120 along the first direction.

[0068] After the clamping member 110 moves along the axial direction of the product 410, it can clamp the product 410 at different positions, which is beneficial for flexibly adjusting the clamping position. In addition, when the length of the product 410 changes, the clamping member 110 can still clamp the product 410 by moving it along the axial direction of the product 410, making the clamping device more compatible.

[0069] Reference Figure 3 In some embodiments of this application, the clamping device further includes a buffer assembly 300, which includes a first connecting seat 380, a second connecting seat 310, and an elastic member 330. The first connecting seat 380 is mounted on the output end 230. The clamping member 110 is mounted on the second connecting seat 310. The elastic member 330 is connected to both the first connecting seat 380 and the second connecting seat 310. The initial deformation of the elastic member 330 is adjustable, and the deformed elastic member 330 can cause the second connecting seat 310 to have a tendency to move closer to the processing position.

[0070] By setting the buffer component 300, when the clamping member 110 comes into contact with the product 410, the elastic member 330 can absorb part of the kinetic energy of the output end 230 through elastic deformation, thereby reducing the impact of the clamping member 110 on the product 410 and reducing the probability of the clamping member 110 damaging the product 410.

[0071] Furthermore, when the clamping member 110 clamps the product 410, the deformed elastic member 330 enables the second connecting seat 310 to have a tendency to move closer to the processing position. Therefore, under the action of the elastic member 330, the clamping member 110 can continuously clamp the product 410, and the clamping effect of the clamping device is better.

[0072] Based on the above effects, by adjusting the initial deformation of the elastic element 330, the clamping element 110 can apply different magnitudes of force to the product 410 when clamping it. This is beneficial to clamp the product 410 with a suitable force, so that the product 410 is not easily damaged or loosened.

[0073] Reference Figure 3 In the improved embodiment described above, the buffer assembly 300 further includes a guide rod 340 and an adjusting member 320. The guide rod 340 is slidably connected to the first connecting seat 380, and one end of the guide rod 340 can abut against the first connecting seat 380 to limit the movement of the guide rod 340 away from the first connecting seat 380. The other end of the guide rod 340 is connected to the second connecting seat 310.

[0074] Adjusting member 320 is installed on guide rod 340, and the position of adjusting member 320 relative to guide rod 340 along the length direction of guide rod 340 is adjustable. Among them, elastic member 330 is compressible, elastic member 330 is sleeved on guide rod 340, one end of elastic member 330 abuts against first connecting seat 380, and the other end of elastic member 330 abuts against adjusting member 320.

[0075] The elastic element 330 is compressible. By changing the position of the adjusting element 320 along the length of the guide rod 340, the compression amount of the elastic element 330 can be adjusted, thereby realizing the adjustment of the initial deformation of the elastic element 330.

[0076] Specifically, the elastic element 330 can be selected from one of the following: a compression spring, a bellows, or a rubber ring.

[0077] Specifically, refer to Figure 3 The adjusting component 320 includes a retaining ring, which is sleeved on the guide rod 340. The retaining ring has a first threaded hole, and the retaining ring is fixed to the guide rod 340 by a set screw that is threaded into the first threaded hole. When it is necessary to adjust the position of the retaining ring, the set screw is loosened, the retaining ring is moved along the length of the guide rod 340 to the target position, and then the set screw is tightened again to complete the adjustment of the initial deformation of the elastic component 330.

[0078] In another embodiment, the adjusting member 320 can also be a clamp, and the initial deformation of the elastic member 330 can be adjusted by adjusting the position of the clamp. Alternatively, the adjusting member 320 can also be a nut, and correspondingly, the guide rod 340 can be machined with a thread, and the nut and guide rod 340 are threaded together. The initial deformation of the elastic member 330 can be adjusted by rotating the nut.

[0079] Specifically, refer to Figure 3The buffer assembly 300 also includes a first linear bearing 370 and a first connecting block 350. The first linear bearing 370 is fixed to the first connecting seat 380 by fasteners. The guide rod 340 is inserted into the first linear bearing 370, thereby realizing the sliding connection between the guide rod 340 and the first connecting seat 380.

[0080] The upper end of the guide rod 340 is fixed with a first connecting block 350 by fasteners. When the guide rod 340 moves downward, the first connecting block 350 can abut against the first linear bearing 370, thereby achieving indirect abutment between one end of the guide rod 340 and the first connecting seat 380, so as to restrict the movement of the guide rod 340 away from the first connecting seat 380.

[0081] The lower end of the guide rod 340 is fixedly connected to the second connecting seat 310 by fasteners. To ensure force balance on the second connecting seat 310, two of each are provided: adjusting member 320, elastic member 330, guide rod 340, and first linear bearing 370. The two guide rods 340 are respectively inserted into the two first linear bearings 370, and the lower ends of the two guide rods 340 are fixed to the second connecting seat 310, while the upper ends of the two guide rods 340 are fixed to the first connecting block 350. Each guide rod 340 is fitted with an adjusting member 320 and an elastic member 330.

[0082] In another embodiment, refer to Figure 4 Alternatively, the elastic element 330 can be a tension spring 391. The upper end of the tension spring 391 is attached to the first connecting block 350, and the lower end of the tension spring 391 is attached to the first connecting seat 380. Initially, the tension spring 391 is in a stretched state. Thus, the deformed elastic element 330 allows the second connecting seat 310 to tend to move closer to the machining position.

[0083] Furthermore, to adjust the initial deformation of the tension spring 391, a first bolt 392 can be added. The first bolt 392 is threaded into the first connecting block 350, and the upper end of the tension spring 391 is hung on the first bolt 392. By rotating the first bolt 392, the initial deformation of the tension spring 391 can be adjusted.

[0084] Reference Figure 3 In some embodiments of this application, the second connecting seat 310 is located on the side of the first connecting seat 380 closer to the processing position, and the maximum distance between the first connecting seat 380 and the second connecting seat 310 can be adjusted.

[0085] When the clamping member 110 presses down on the product 410, the elastic member 330 deforms, and the distance between the first connecting seat 380 and the second connecting seat 310 decreases. Therefore, when the clamping member 110 is not pressing down on the product 410, the distance between the first connecting seat 380 and the second connecting seat 310 is at its maximum.

[0086] The clamping member 110 is mounted on the second connecting seat 310. By adjusting the maximum distance between the first connecting seat 380 and the second connecting seat 310, the initial position of the clamping member 110 relative to the first connecting seat 380 can be adjusted. By adjusting the maximum distance between the first connecting seat 380 and the second connecting seat 310, the clamping member 110 can be compatible with products 410 of different diameters, thus enhancing the compatibility of the clamping device.

[0087] Reference Figure 5 In some embodiments of this application, the buffer assembly 300 further includes an adjusting screw 360, which is threadedly engaged with the first connecting seat 380. One end of the adjusting screw 360 can abut against the second connecting seat 310 to limit the movement of the second connecting seat 310 away from the first connecting seat 380.

[0088] Therefore, by rotating the adjusting screw 360 relative to the first connecting seat 380, the maximum distance between the first connecting seat 380 and the second connecting seat 310 can be adjusted. The structure is simple and easy to use.

[0089] Specifically, to ensure that the head of the adjusting screw 360 abuts against the second connecting seat 310, the second connecting seat 310 has a second through hole 311. The tail of the adjusting screw 360 passes through the second through hole 311 and engages with the first connecting seat 380 via a thread. When the second connecting seat 310 moves away from the first connecting seat 380, the head of the adjusting screw 360 abuts against the second connecting seat 310, thereby limiting the maximum distance between the first connecting seat 380 and the second connecting seat 310.

[0090] Reference Figure 6 In some embodiments of this application, the adjusting screw 360 is threadedly engaged with the second connecting seat 310, and one end of the adjusting screw 360 can abut against the first connecting seat 380 to limit the movement of the second connecting seat 310 away from the first connecting seat 380.

[0091] Therefore, by rotating the adjusting screw 360 relative to the second connecting seat 310, the maximum distance between the first connecting seat 380 and the second connecting seat 310 can be adjusted. The structure is simple and easy to use.

[0092] Specifically, to ensure that the head of the adjusting screw 360 abuts against the first connecting seat 380, the first connecting seat 380 has a first through hole 381. The tail of the adjusting screw 360 passes through the first through hole 381 and then engages with the second connecting seat 310 via a thread. When the second connecting seat 310 moves away from the first connecting seat 380, the head of the adjusting screw 360 will abut against the first connecting seat 380, thereby limiting the maximum distance between the first connecting seat 380 and the second connecting seat 310.

[0093] Reference Figure 3In some embodiments of this application, the adjusting screw 360 is threadedly engaged with the first connecting block 350, and one end of the adjusting screw 360 can abut against the first connecting seat 380 to limit the movement of the second connecting seat 310 away from the first connecting seat 380.

[0094] Therefore, by rotating the adjusting screw 360 relative to the first connecting block 350, the maximum distance between the first connecting seat 380 and the second connecting seat 310 can be adjusted. The structure is simple and easy to use.

[0095] Reference Figure 3 and Figure 7 In some embodiments of this application, the direction in which the clamping member 110 approaches or moves away from the processing position is defined as the second direction (refer to...). Figure 3 (For example, the second direction is the up-down direction). The drive module 200 includes a base 221, a cam 223, a drive member 228, and a follower 229. The follower 229 is slidably connected to the base 221, and the sliding direction of the follower 229 relative to the base 221 is the second direction. A clamping member 110 is mounted on the follower 229. The cam 223 is rotatably or slidably connected to the base 221. The cam 223 has a drive surface 242, which is used to push the follower 229. The drive member 228 is used to drive the cam 223 to move relative to the base 221, so that the follower 229 moves relative to the base 221 in the second direction.

[0096] Therefore, when the drive member 228 drives the cam 223 to rotate or slide relative to the base 221, the drive surface 242 of the cam 223 can push the follower 229 to slide in the second direction relative to the base 221, thereby driving the clamping member 110 to move in the second direction. The clamping member 110 can move closer to or further away from the processing position, and the clamping member 110 can normally clamp or release the product 410.

[0097] By setting cam 223, the movement of drive member 228 can be converted into the movement of follower member 229 along the second direction, without having to make the drive direction of drive member 228 along the second direction. Thus, drive member 228 can be flexibly installed according to spatial position, and the spatial allocation of the clamping device can be more reasonable.

[0098] Specifically, the drive component 228 can be a cylinder, a linear motor, or an electric cylinder, etc.

[0099] Specifically, refer to Figure 7 The drive module 200 also includes a second sliding component 222, which includes a second slider and a second slide rail. The second slider and the second slide rail are slidably connected. The second slider is fixed to the cam 223 by fasteners, and the second slide rail is fixed to the base 221 by fasteners. Thus, the cam 223 and the base 221 are slidably connected.

[0100] The cam 223 is provided with a guide groove 241. The inner surface of the guide groove 241 is a driving surface 242. The driving surface 242 includes an inclined surface 243. The angle between the inclined surface 243 and the second direction is greater than zero (e.g., 30 degrees, 45 degrees, 60 degrees or other angles). The angle between the length direction of the second slide rail and the extension direction of the inclined surface 243 is greater than zero (e.g., 30 degrees, 45 degrees, 60 degrees or other angles).

[0101] The drive module 200 also includes a first bearing 245, which is sleeved on a first rotating shaft 244. One end of the first rotating shaft 244 is fixed to a follower 229. The first bearing 245 is placed in a guide groove 241 and can roll along the drive surface 242. The first bearing 245 is mainly used to reduce the friction between the cam 223 and the follower 229.

[0102] Therefore, when the cam 223 moves, the inclined surface 243 can push the clamping member 110 to move in the second direction.

[0103] Specifically, refer to Figure 3 The drive module 200 also includes a second connecting block 225, a guide rod 226, and a second linear bearing 227. The second linear bearing 227 is fixed to the first connecting seat 380 by fasteners, and the guide rod 226 passes through the second linear bearing 227. The lower end of the guide rod 226 is fixed to the base 221 by fasteners, and the upper end of the guide rod 226 is fixed to the second connecting block 225 by fasteners. The length direction of the guide rod 226 is set along the second direction.

[0104] Thus, the follower 229 achieves a sliding connection with the base 221, and the sliding direction of the follower 229 relative to the base 221 is the second direction.

[0105] The drive module 200 also includes a first compression spring 224. The first compression spring 224 is sleeved on the guide rod 226, and the upper end of the first compression spring 224 abuts against the first connecting seat 380, and the lower end of the first compression spring 224 abuts against the first connecting seat 380. The first compression spring 224 is mainly used to assist the drive component 228 to realize the upward movement of the entire buffer assembly 300.

[0106] In another embodiment, the cam 223 can be rotatably connected to the base 221 via a shaft and bearings. In this case, the guide groove 241 can be configured as an annular groove, thereby driving the follower 229 to move relative to the base 221 in a second direction.

[0107] It should be noted that in this embodiment, the follower 229 serves as the output terminal 230 of the drive module 200.

[0108] It should be noted that the base 221, the second sliding component 222, the cam 223, the first compression spring 224, the second connecting block 225, the guide rod 226, the second linear bearing 227, the driving component 228, the driven component 229, the first rotating shaft 244, and the first bearing 245 constitute the second driving component 220.

[0109] In another embodiment, the second drive component 220 may also be selected from one of the following: a linear motor, a hydraulic cylinder, an electric cylinder, a motor-driven rack and pinion mechanism, a motor-driven sprocket and chain mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven crank-slider mechanism.

[0110] The working process of the clamping device will be explained in conjunction with the above embodiments.

[0111] The first step is to adjust the initial deformation of the elastic element 330 to the target range by adjusting the position of the adjusting element 320.

[0112] The second step is to adjust the maximum distance between the first connecting seat 380 and the second connecting seat 310 by rotating the adjusting screw 360, thereby adjusting the clamping member 110 to the initial position suitable for the diameter of the current product 410.

[0113] The third step is to load product 410 into the processing position through the first area 120 (it can be loaded by a robotic arm).

[0114] Fourth step: The first cylinder 211 is activated, pushing the second drive assembly 220 and the buffer assembly 300 together into the first area 120, and causing the clamping member 110 to move to the target position above the product 410.

[0115] Fifth step: Drive component 228 starts, cam 223 moves backward, causing clamping component 110 to move down and clamping component 110 to press against the outer peripheral surface 411 of product 410.

[0116] Step 6: After product 410 is processed, drive component 228 is activated, cam 223 moves forward, causing clamping component 110 to move upward.

[0117] Step 7: The first cylinder 211 is activated, pushing the second drive assembly 220 and the buffer assembly 300 to leave the first area 120 together.

[0118] Step 8: Repeat steps 3 through 7.
