If the shell entry method is changed and a vertical shell entry process is adopted, due to the product structure, the positive pole of the shell and the core are not concentric during the processing, which will cause the problem of cold welding in the subsequent process of welding the positive pole.

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Combine the following Figure 1-Figure 6 The utility model describes a cylindrical battery pole correction device.

[0039] In this embodiment, Figures 1 to 3 As shown, the cylindrical battery pole correction device includes: a column 20, a carrier mechanism 10, a drive mechanism 30 and a correction mechanism 40. The column 20 is used to be set on the ground. The carrier mechanism 10 is used to carry the battery cell; the drive mechanism 30 is installed on the column 20; the correction mechanism 40 is coaxially arranged with the carrier mechanism 10, and the correction mechanism 40 includes a positioning component 410 and a correction component 420, the positioning component 410 is installed at the output end of the drive mechanism 30, and the correction component 420 is installed on the positioning component 410.

[0040] Next, the functions and working principles of each component are introduced in detail.

[0041] First, the column 20 is the foundation of the entire device. It is stably set on the ground and provides a solid foundation for the entire device. The height and diameter of the column 20 can be adjusted according to actual needs to meet the battery pole correction needs of different scenarios and specifications.

[0042] The carrier mechanism 10 is another important component, which is responsible for carrying the battery cell. The design of the carrier mechanism 10 should ensure that the battery cell is stable and motionless during the correction process to avoid poor correction effect due to vibration or movement. The carrier mechanism 10 can be customized according to the shape and size of the battery cell to achieve correction of various types of battery cells.

[0043] The driving mechanism 30 is installed on the column 20, and its main function is to provide power so that the correction device can operate automatically. The driving mechanism 30 can be driven by a motor, pneumatic or hydraulic drive, and the specific selection should be determined according to the actual application scenario and requirements.

[0044] The correction mechanism 40 is the core part of this embodiment, which includes a positioning component 410 and a correction component 420. The positioning component 410 is installed at the output end of the driving mechanism 30, and its main function is to preliminarily determine the fit for the downward pressure to complete the shell insertion. The correction component 420 is installed on the positioning component 410 and is responsible for implementing specific correction actions.

[0045] During the operation, the battery cell and the battery shell follow the magnetic suspension line. After arriving at this station, the carrier mechanism carries the battery cell, and the positioning component 410 takes the battery shell. Driven by the driving mechanism 30, the battery shell and the battery cell are pressed concentrically. During the whole process, the correction component 420 concentrically positions the battery shell and the battery, so that the battery cell and the battery shell are coaxially positioned.

[0046] It is worth mentioning that the correction device can also be equipped with a monitoring system to monitor the correction process in real time to ensure the quality and safety of the correction. The monitoring system can detect the correction status of the battery cell, such as the correction speed, correction strength, etc., and adjust the correction parameters in time to achieve the best correction effect.

[0047] The cylindrical battery pole correction device provided by the utility model can use the positioning component 410 of the correction mechanism 40 to take the battery shell by arranging the correction mechanism 40 coaxial with the carrier mechanism 10 on the column 20. In the process of positioning and pressing down the battery cell and the battery shell, the correction component 420 of the correction mechanism 40 can re-position and correct the battery shell, and drive the correction mechanism 40 to press down through the driving mechanism 30, thereby ensuring the concentricity of the positive pole of the battery cell and the battery shell, and avoiding the problem of cold welding caused by the welding of the positive pole in the subsequent process.

[0048] In some embodiments, Figures 1 to 3 As shown, the positioning assembly 410 is used to position the battery housing; the positioning assembly 410 is coaxially arranged with the correction assembly 420, the correction assembly 420 passes through the positioning assembly 410, and the correction assembly 420 is movable along the axial direction of the positioning assembly 410 to correct the pole end of the battery housing and the position of the battery cell.

[0049] During operation, the positioning assembly 410 grabs and positions the battery housing, the carrier mechanism carries the battery cell, and the positioning assembly 410 takes the battery housing. At this time, the correction assembly 420 is controlled to press down through the pole end of the battery housing to position the battery housing. Under the drive of the driving mechanism 30, the battery housing and the battery cell are pressed in concentrically. During the process, the correction assembly 420 concentrically positions the battery housing and the battery, so that the battery cell and the battery housing are coaxially positioned.

[0050] In one example, if Figure 3 As shown, the correction component 420 includes a push rod 4210 and a positioning pin 4220 . The push rod 4210 is installed at the axis of the positioning component 410 , and the positioning pin 4220 is installed at the output end of the push rod 4210 .

[0051] Among them, the push rod 4210 is one of an electric push rod and a cylinder. Since the positioning pin 4220 is installed at the output end of the push rod 4210, the push rod 4210 can control the axial movement of the positioning pin 4220 along the positioning assembly 410.

[0052] Specifically, the positioning assembly 410 is provided with a slide groove arranged along its axial direction, and the push rod 4210 can move along the slide groove. During operation, when the push rod 4210 moves in the slide groove, it can control the positioning pin 4220 to penetrate into the battery housing and the battery core, or to separate from the battery housing and the battery core, so as to complete the positioning of the battery housing and the battery core.

[0053] For positioning, a pressure plate 4230 is provided on the peripheral wall of the positioning pin 4220. A pin head is provided at the bottom of the positioning pin 4220, and a pressure plate 4230 is provided around the pin head for positioning with the battery housing. During the process of positioning and pressing down the battery cell and the battery housing, the pressure plate 4230 can complete the positioning with the battery housing, and the pin head is inserted into the battery housing and the battery cell at the same time, so as to position and correct the battery housing.

[0054] In order to ensure the stability and safety of the battery cell in the battery housing, the design and application of the positioning pin 4220 is particularly important. The positioning pin 4220 can not only realize the precise positioning of the battery cell and the battery housing, but also correct the battery housing, thereby ensuring the close connection between the battery cell and the battery housing.

[0055] During the battery assembly process, the pin head of the positioning pin 4220 and the pressure plate 4230 play a key role. During the process of positioning and pressing the battery cell and the battery shell, the pin head can ensure that the contact surface between the battery cell and the battery shell is fully in contact, thereby improving the performance of the battery. At the same time, the pressure plate 4230 reduces the gap between the battery cell and the battery shell by applying pressure to the battery shell, further improving the sealing performance of the battery.

[0056] In addition, the design of the positioning pin 4220 also needs to consider factors such as the material, size and shape of the battery cell and battery housing. Depending on the battery type and application scenario, the size, shape and material selection of the positioning pin 4220 will also vary. In actual applications, in order to ensure the reliability and safety of the battery, the positioning pin 4220 needs to match the size of the battery housing and the battery cell to achieve accurate positioning and correction.

[0057] To meet the positioning requirements, the pin head of the positioning pin 4220 is provided with a chamfer that matches the battery housing and the battery cell. The chamfer is designed to ensure that the battery cell is well fixed in the housing while avoiding performance degradation due to friction between the battery cell and the housing. In practical applications, the chamfer of the pin head of the positioning pin 4220 can easily enter the battery housing and the battery cell hole, thereby ensuring the concentricity of the battery cell and the positive pole of the battery housing.

[0058] Alternatively, if Figures 1 to 3 As shown, the positioning component 410 takes the battery housing by one of negative pressure suction, magnetic suction or clamping.

[0059] When negative pressure suction is adopted, the positioning component 410 is an air suction clamp, which is arranged at the output end of the driving mechanism 30. When the air suction clamp is opposite to the battery shell, the battery shell can be grasped by the action of negative pressure.

[0060] When the magnetic suction method is adopted, the positioning component 410 is a magnetic clamp, which is arranged at the output end of the driving mechanism 30. When the magnetic clamp is opposite to the battery shell, the battery shell can be grasped by magnetic suction.

[0061] When the direct grasping method is adopted, the positioning assembly 410 includes two opposing clamps, and the battery housing can be grasped or released by adjusting the size of the clamping space between the clamps.

[0062] In addition, the positioning assembly 410 is designed with a spring buffer mechanism and is installed with a pressure sensor. The pressure sensor detects the pressure in real time to ensure that the product will not be crushed when entering the shell.

[0063] Based on the above embodiments, in one embodiment, Figures 1 to 3 As shown, the positioning assembly 410 is a multi-claw cylinder, which includes a cylinder body 4110 and a clamp 4120. The clamp 4120 slides radially along the cylinder body 4110 to clamp and position the battery shell; the correction assembly 420 is located at the center of the cylinder body 4110 and moves axially along the cylinder body 4110 to correct the pole end of the battery shell and the position of the battery cell.

[0064] Specifically, the multi-claw cylinder can adopt a three-claw cylinder, and the corresponding three-claw cylinder is provided with three clamping claws 4120 arranged along a ring to grasp the battery cell shell, and the clamping claws 4120 can be controlled by the three-claw cylinder to grasp or release the battery shell. After the three-claw cylinder grasps the battery shell, the correction component 420 can be controlled to press down through the pole end of the battery shell, so as to position the battery shell. Then, under the drive of the driving mechanism 30, the battery shell and the battery cell are pressed in concentrically. During the whole process, the correction component 420 concentrically positions the battery shell and the battery, so that the battery cell and the battery shell are coaxially positioned.

[0065] In another embodiment, the positioning assembly may be a rotary cylinder, which includes a cylinder body and a rotary clamp. The rotary clamp slides radially along the cylinder body to clamp and position the battery housing. Unlike a multi-claw cylinder, the clamp of the rotary cylinder is a single claw, and the rotation of the clamp driven by the rotary cylinder is used to grasp and release the battery housing. The correction assembly is located at the center of the cylinder body and moves along the axial direction of the cylinder body to correct the pole end of the battery housing and the position of the battery cell.

[0066] like Figures 1 to 3 As shown, the correction mechanism 40 also includes a coordinate sensor installed on one side of the positioning component 410 , and the coordinate sensor is used to locate the position point of the battery housing to control the driving mechanism 30 .

[0067] During operation, the coordinate sensor locates the position of the battery housing in real time and transmits the position information to the corresponding control mechanism, so as to control the operation of the drive mechanism 30 through the control mechanism, thereby ensuring that the battery cell can be smoothly introduced into the battery housing when the shell is pressed down.

[0068] In addition, if Figures 1 to 3 As shown, the driving mechanism 30 includes a vertically movable slide 310 and a first power assembly 320; the output end of the first power assembly 320 is connected to a sliding member 330, and the sliding member 330 is movably arranged on the vertically movable slide 310, and the output end of the first power assembly 320 is connected to the positioning assembly 410 through the sliding member 330. The positioning assembly 410 is connected to the output end of the first power assembly 320 through the sliding member 330, so that the first power assembly 320 can control the downward pressure of the positioning assembly 410, so that the battery cell can be smoothly introduced into the battery housing.

[0069] Based on the above embodiments, in some embodiments, such as Figures 4 to 6As shown, the carrier mechanism 10 includes a mounting seat 1100, a mounting platform 1200, a clamping assembly 1300 and a second power assembly 1400. The mounting platform 1200 is arranged opposite to the mounting seat 1100; the clamping assembly 1300 includes a transmission structure and two clamping plates 1330, the two clamping plates 1330 are slidably mounted on the mounting platform 1200, and one end of the transmission structure is fixedly connected to the two clamping plates 1330 respectively; the second power assembly 1400 is installed on the mounting seat 1100, and the second power assembly 1400 is connected to the other end of the transmission structure, and the second power assembly 1400 drives the clamping assembly 1300 to clamp the battery cell through the transmission structure. The utility model can drive the two clamping plates 1330 of the clamping assembly 1300 to open and close to firmly clamp the battery cell by setting the second power assembly 1400 and the transmission structure, and the positioning and clamping accuracy is high, which can meet higher process requirements.

[0070] Specifically, the second power assembly 1400 includes a first lifting structure 1410, which is arranged opposite to the transmission structure; the transmission structure includes a top rod 1310 and two hinged rods 1320, the first lifting structure 1410 is used to lift one end of the top rod 1310, one end of the two hinged rods 1320 is hinged to the other end of the top rod 1310, two clamping plates 1330 are respectively connected to the other ends of the two hinged rods 1320, and a clamping space for clamping the battery cell is formed between the two clamping plates 1330. The battery cell is installed in the clamping space, and the two sides of the battery cell are respectively abutted against the two clamping plates 1330. The first lifting structure 1410 can be configured as a cylinder with a vertical stroke, which is used to lift the push rod 1310. The push rod 1310 further drives the hinged rod 1320 while moving. The hinged rod 1320 contracts or opens to open or close the two clamps 1330, so that the battery cell can be firmly clamped in the clamping space.

[0071] In an optional embodiment, the utility model adopts a "three-point positioning" method to clamp the battery cell, which can achieve a more ideal clamping effect and greatly improve the problem of unstable clamping and affecting production effect that is prevalent in the field. Specifically, on the basis of the above technical solution, a group of rollers 1340 is provided on one clamping plate 1330, and two groups of rollers 1340 are provided on the other clamping plate 1330. Through the three groups of rollers 1340 at different positions installed on the clamping plate 1330, the cylindrical battery cell is firmly positioned by point contact. It should be noted that each group of rollers 1340 includes two rollers 1340 arranged in sequence in the vertical direction, so that a good and stable clamping effect can be achieved for the cylindrical battery. Of course, each group can have one or more rollers 1340, and the utility model does not limit this. It should also be noted that the rollers 1340 are in rolling contact with the side walls of the battery cell, and their friction is smaller, and it is not easy to damage the battery cell during the clamping process, affecting the quality of the battery cell.

[0072] Furthermore, if Figures 4 to 6 As shown, the opening and closing effect of the clamping plate 1330 is crucial for the processing of the battery core. In order to obtain a stable and smooth opening and closing effect, the mutual coordination and connection between the structures are made more efficient and easy. The carrier mechanism 10 provided by the utility model also includes a mounting plate 1210 slidably connected to the mounting platform 1200, and the clamping assembly 1300 is slidably connected to the mounting plate 1210.

[0073] Specifically, the clamping assembly 1300 also includes a first slide rail 1211 and a second slide rail 1212 spaced apart on the mounting plate 1210, the first slide rail 1211 extends along a first direction, two clamping plates 1330 are respectively slidably connected to the first slide rail 1211, the second slide rail 1212 extends along a second direction, the top rod 1310 is slidably connected to the second slide rail 1212, and the first direction is perpendicular to the second direction. In the technical solution provided in this embodiment, the first direction is a horizontal direction, the second direction is a vertical direction, the top rod 1310 slides in a vertical direction through the second slide rail 1212, and the two clamping plates 1330 slide in a horizontal direction through the first slide rail 1211. It should be noted that under the driving action of the first lifting structure 1410, the top rod 1310 moves in a vertical direction, and the two clamping plates 1330 hinged thereto have a relatively close or relatively far movable stroke to clamp or release the battery cell. It should be noted that, in actual application, in order to meet the requirements of the battery cell process, the first direction and the second direction may also be directions other than the horizontal and vertical directions.

[0074] As mentioned above, for the clamping of the battery cell, the "three-point positioning" method can be used to improve the clamping accuracy, so that the side wall of the battery cell is in stable contact with the clamping plate 1330. In addition, in order to achieve a good clamping effect, a moderate clamping force is also indispensable. Specifically, in the technical solution provided by the utility model, the clamping assembly 1300 also includes two tension springs 1350, and the two ends of each tension spring 1350 are respectively connected to each clamping plate 1330, and the two tension springs 1350 are arranged in parallel and are centrally symmetrically distributed. In this way, the two tension springs 1350 are respectively connected to the clamping plates 1330, so that the clamping plates 1330 tightly clamp the battery cell in the initial state due to the elastic force of the tension springs 1350, and the clamping plates 1330 are driven to open through the driving action of the first lifting structure 1410.

[0075] It should be noted that the clamping effect should be moderate. Too much is as bad as too little. In the production process, the clamping plate 1330 often clamps the battery cell too tightly, causing damage to the battery cell. Figures 4 to 6As shown, the utility model adds a limiting mechanism, that is, a screw hole 1331 is provided on one clamping plate 1330, and a limiting block 1332 is provided on one side of the other clamping plate 1330. The clamping assembly 1300 also includes a screw rod 1333 passing through the screw hole 1331. When each clamping plate 1330 clamps the battery cell, the screw rod 1333 abuts against the limiting block 1332, so that the movable stroke of the clamping plate 1330 is fixed. In general, the screw rod 1333 can be adjusted to match the clamping distance between the two clamping plates 1330 with the diameter of the battery cell, effectively avoiding the problem of damaging the battery cell. In addition, by adjusting the screw rod 1333, the use requirements of battery cells of different sizes can also be met.

[0076] It should be noted that in order to meet the needs of different processes, there are multiple workstations in the production process. To match the needs of multiple workstations, the carrier mechanism 10 needs to have a corresponding movable stroke. Specifically, in the technical solution provided by the utility model, the second power assembly 1400 also includes a second lifting structure 1420 disposed on the mounting seat 1100, the first lifting structure 1410 is disposed on the second lifting structure 1420, and the second lifting structure 1420 is used to drive the mounting plate 1210 to slide along the mounting platform 1200.

[0077] Furthermore, if Figures 4 to 6 As shown, the mounting platform 1200 is provided with a third slide rail 1213, the third slide rail 1213 extends along the second direction, and the mounting plate 1210 is slidably connected to the third slide rail 1213. If there are multiple workstations in the vertical direction, the mounting platform 1200 is provided with the third slide rail 1213 in the vertical direction, and the mounting plate 1210 is slidably connected to the third slide rail 1213, so that the clamping assembly 1300 can be movable in the vertical direction, so that it can move up and down according to the process requirements, and flexibly adapt to various process requirements.

[0078] During the vertical movement of the carrier, after the lifting cylinder is lowered, the carrier will drop due to its own weight. In order to reduce the impact load, in the technical solution provided by the utility model, a first limit plate 1220 is convexly provided on the side of the mounting platform 1200 facing the mounting plate 1210, and a second limit plate 1230 is convexly provided on the side of the mounting plate 1210 facing the mounting platform 1200. An elastic member 1240 is provided between the first limit plate 1220 and the second limit plate 1230, and a buffer 1250 is also provided on the first limit plate 1220. By setting the elastic member 1240 and the buffer 1250, the impact load can be effectively reduced to ensure the safety and stability of the structure.

[0079] Furthermore, in order to ensure that the cylinder does not damage the mechanical structures in various places, high-strength glue can be set at the junction of the cylinder and the structure, so that the impact load of the cylinder can also be softened by the high-strength glue to prevent structural damage caused by hard collisions. In addition, in order to ensure the load-bearing effect of the battery cell in the vertical direction, the mounting plate 1210 in this solution is also provided with a connecting plate extending in the horizontal direction, and a supporting cup 1214 is provided on the connecting plate. The supporting cup 1214 supports the battery cell from the bottom of the battery cell. The supporting cup 1214 can also be set as a conductive structure. When performing a short-circuit test on the battery cell, the cylindrical battery cell can complete this process on the carrier, which saves a lot of trouble of repeated disassembly and assembly and improves the detection efficiency. It should be noted that an opening is provided on the connecting plate, and the push rod 1310 can be movably passed through the opening for movement.

[0080] like Figures 4 to 6 As shown, the carrier mechanism 10 is also provided with a position sensor; the position sensor is used to detect the position of the battery cell in the battery housing, and after the battery cell is lifted to a preset position in the battery housing, the second power assembly 1400 is controlled to drive the two clamping plates 1330 to release the battery cell through the transmission structure. The position sensor can be a position switch or other sensors, which can be set on one side of the battery housing to directly detect the position of the battery cell in the battery housing.

[0081] In a specific embodiment, Figures 1 to 6 As shown, the method of vertically inserting the cylindrical battery into the shell is as follows: After the device is turned on,

[0082] After the battery cell and the battery shell follow the magnetic suspension line and arrive at this station, the carrier mechanism carries the battery cell, and the positioning assembly 410 grabs the battery shell, and the battery shell is located above the battery cell. After the carrier mechanism 10 lifts a part of the battery cell to a preset position in the battery shell, the carrier mechanism 10 is controlled to release the battery cell, and the driving mechanism 30 controls the correction mechanism 40 to press down the battery shell, so that the battery cell can be loaded into the battery shell. Under the driving action of the first lifting structure 1410, the carrier mechanism 10 clamps or releases the battery cell, and the top rod 1310 moves in the vertical direction, so that the two clamping plates 1330 hinged thereto have a relatively close or relatively far movable stroke to clamp or release the battery cell. During the whole process, the correction assembly 420 concentrically positions the battery shell and the battery, so that the battery cell and the battery shell are coaxially positioned.
