Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing equipment technology, specifically to a rotary clamping mechanism. Background Technology

[0002] In the later stages of lithium battery production, such as formation, capacity testing, and sorting, battery cells are typically placed on standardized trays for circulation. During this circulation, the orientation of the cells within the trays is usually fixed. However, at specific workstations, such as when removing defective products or when the orientation of the cell's tabs needs to be changed to meet the requirements of the next process, the cells must be removed from the trays, rotated above the trays, and then placed on another tray or on another logistics line.

[0003] Currently, production lines mostly use robotic arms and rotary clamping mechanisms to grasp, rotate, and place battery cells. A rotary clamping mechanism typically consists of a rotary drive assembly and a clamping assembly mounted at its output end.

[0004] However, when the existing rotary clamping mechanism lowers the battery cell after it has been rotated, if there are tolerances in the tray size or the thickness of the battery cell itself, the battery cell will have a rigid collision with the tray, which will damage the battery cell and even impact the rotary clamping mechanism itself, affecting the service life of the rotary clamping mechanism. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a rotary clamping mechanism. By setting a floating component between the rotary component and the clamping component, the rigid impact between the clamping component and the battery cell, and between the battery cell and the tray can be buffered, thus avoiding damage to the battery cell and the clamping component and ensuring product quality and equipment safety.

The clamping blocks are provided with an upper baffle for blocking the top of the battery cell.

[0010] As a further improvement to the above technical solution, the number of sliding rods is four, and the four sliding rods are distributed in a rectangular array around the rotation center of the rotating seat.

[0011] As a further improvement to the above technical solution, a sensing plate is provided on one side of the upper mounting plate, and a first bracket is provided on one side of the lower mounting plate. A proximity switch is installed on the first bracket, and the proximity switch is used to sense whether the sensing plate has entered its sensing area.

Detailed Implementation

[0021] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0022] Reference Figures 1 to 3The present invention provides a rotating clamping mechanism, including a rotating component 100, a clamping component 200, and a floating component 300 disposed between the rotating component 100 and the clamping component 200. The floating component 300 is used to enable the clamping component 200 to float relative to the rotating component 100 along the rotation axis.

[0023] Structurally, the rotating assembly 100 includes a first support 110, a first drive member 120, and a rotating seat 130. The first support 110 is mounted on a robotic arm (not shown in the figure), the first drive member 120 is mounted on the first support 110, and the rotating seat 130 is disposed at the output end of the first drive member 120. The first drive member 120 is used to drive the rotating seat 130 to rotate.

[0024] Positionally, the clamping assembly 200 is located directly below the rotating assembly 100. The clamping assembly 200 includes two clamping blocks 210 and a second driving member 220 for driving the two clamping blocks 210 to move closer or further apart from each other. An upper baffle 230 is provided on the clamping block 210 for blocking the top of the battery cell.

[0025] Furthermore, the floating assembly 300 includes an upper mounting plate 310, a lower mounting plate 320, a plurality of slide rods 330, and a plurality of springs 340. The upper mounting plate 310 is fixedly connected to the rotating seat 130. The second driving member 220 is mounted on the lower mounting plate 320. The top end of the slide rod 330 is fixedly connected to the upper mounting plate 310. The springs 340 are sleeved on the outer periphery of the slide rod 330. The top end of the slide rod 330 is fixedly connected to the upper mounting plate 310. The springs 340 are sleeved on the outer periphery of the slide rod 330. The slide rod 330 is slidably connected to the lower mounting plate 320. The two ends of the springs 340 abut against the upper mounting plate 310 and the lower mounting plate 320, respectively. The bottom of the slide rod 330 is provided with a limiting flange 350 to restrict the lower mounting plate 320 from disengaging.

[0026] When it is necessary to change the orientation of the battery cell's tabs, the robotic arm drives the rotating clamping mechanism to descend as a whole. The upper baffle 230 on the clamping plate first abuts against the top of the battery cell. At this time, both the clamping assembly 200 and the lower mounting plate 320 are blocked by the battery cell and cannot descend. Meanwhile, the rotating assembly 100 drives the upper mounting plate 310 to continue descending against the elastic force of the spring 340. The slide bar 330 slides downward relative to the lower mounting plate 320, and the spring 340 is compressed. Then, the second drive member 220 drives the two clamping blocks 210 to move closer together to clamp the battery cell. Next, the robotic arm drives the rotating... The rotating clamping mechanism rises as a whole, removing the battery cell from the tray. The lower mounting plate 320 slides downwards along the length of the slide bar 330 under the force of the spring 340 until it is blocked by the limiting flange 350 at the bottom of the slide bar 330. Next, the first driving member 120 drives the rotating seat 130 to rotate at a certain angle. The rotating seat 130 drives the floating component 300, the clamping component 200, and the battery cell to rotate synchronously at a certain angle. Then, the robotic arm drives the rotating clamping mechanism to move and descend as a whole, placing the battery cell into another tray. Because both the tray and the battery cell have dimensional tolerances, during the descent of the rotating clamping mechanism driven by the robotic arm, the battery cell first contacts the tray. As the robotic arm continues to descend, the battery cell, clamping component 200, and lower mounting plate 320 are all blocked by the tray, while the rotating component 100 drives the upper mounting plate 310 to continue descending against the force of the spring 340. The slide bar 330 slides downwards relative to the lower mounting plate 320, compressing the spring 340. Finally, the first drive unit 120 drives the two clamping blocks 210 to move away from each other to release the battery cell, and the robotic arm drives the rotating clamping mechanism to rise and reset as a whole.

[0027] Therefore, by setting the floating component 300, this utility model can buffer the rigid impact between the clamping component 200 and the battery cell, and between the battery cell and the tray, thus avoiding damage to the battery cell and the clamping component 200.

[0028] In some preferred embodiments, a plurality of linear bearings 360 are provided on the lower mounting plate 320, and the plurality of linear bearings 360 are respectively in sliding engagement with a plurality of slide rods 330.

[0029] Understandably, by setting up several linear bearings 360, the linear bearings 360 can provide precise sliding guidance for the slide rod 330, ensuring that the lower mounting plate 320 can only float up and down along the axial direction of the slide rod 330, thereby preventing the lower mounting plate 320 from jamming or swaying, and ensuring stability during the clamping process.

[0030] Specifically, there are four slide rods 330, which are arranged in a rectangular array around the rotation center of the rotating seat 130. This can distribute the load and impact force to the four support points, making the lower mounting plate 320 evenly stressed. This prevents the slide rods 330 from tilting with the linear bearing 360, thus avoiding jamming or accelerated wear and improving the stability and reliability of the mechanism.

[0031] In some preferred embodiments, a sensing element 370 is provided on one side of the upper mounting plate 310, and a first bracket 380 is provided on one side of the lower mounting plate 320. A proximity switch 390 is mounted on the first bracket 380, and the proximity switch 390 is used to sense whether the sensing element 370 has entered its sensing area.

[0032] Understandably, when the upper mounting plate 310 descends relative to the lower mounting plate 320 against the elastic force of the spring 340, the slide bar 330 slides downward relative to the lower mounting plate 320, compressing the spring 340. If the sensing plate 370 on the upper mounting plate 310 enters the sensing area of ​​the proximity switch 390, the proximity switch 390 transmits a signal to the equipment's control system. The equipment's control system then controls the robotic arm to stop driving the rotating clamping mechanism downwards. This prevents the spring 340 from being compressed to its fatigue limit, extends the service life of the spring 340, and improves the stability of the equipment.

[0033] In some preferred embodiments, the first drive component 120 is a rotary cylinder. The rotary cylinder has a simple and compact structure, making it easy to install at the end of the robotic arm, reducing the load on the robotic arm, thereby reducing the manufacturing cost and subsequent maintenance cost of the equipment.

[0034] In some preferred embodiments, the second driving member 220 is a finger cylinder, and each of the two output ends of the finger cylinder is provided with a second support 240. Two clamping blocks 210 are respectively installed on the two second supports 240, and a limit stop 250 and an adjustable limit module 260 are respectively provided on the opposite side of the two second supports 240.

[0035] Understandably, the compact structure of the finger cylinder allows it to move the two clamping blocks 210 closer or further apart simultaneously. Furthermore, by incorporating a limiting stop 250 and an adjustable limiting module 260, when the finger cylinder moves the two clamping blocks 210 to grip the battery cell, the limiting stop 250 and adjustable limiting module 260 on opposite sides of the two second supports 240 abut against each other. This ensures consistent clamping force each time, thereby preventing the finger cylinder from excessively squeezing the battery cell due to air pressure fluctuations or improper stroke settings, thus reducing damage to the battery cell.

[0036] Furthermore, the adjustable limit module 260 includes a connecting seat 261, a nut 262 disposed on the connecting seat 261, and a bolt 263 threadedly connected to the nut 262. The bolt 263 is coaxially disposed with the limit stop 250, and the head of the bolt 263 faces the limit stop 250. Both the connecting seat 261 and the corresponding second support 240 are provided with clearance holes 241 for the threaded part of the bolt 263 to be inserted.

[0037] Understandably, when the finger cylinder drives the two clamping blocks 210 to hold the battery cell, the head of the bolt 263 abuts against the end of the limit stop 250. At this time, the distance between the two second supports 240 is at its minimum. When changing to a different specification of battery cell, simply use a tool to rotate the bolt 263 to fine-tune the minimum distance between the two second supports 240. Therefore, the operator does not need to replace the entire gripper or adjust the air pressure or electrical parameters of the finger cylinder, thereby improving the efficiency of cell changing.

[0038] In some preferred embodiments, a second bracket 280 is provided on one of the second supports 240, and a photoelectric sensor 281 is provided on the second bracket 280. The photoelectric sensor 281 is used to detect whether there is a battery cell between the two clamps 210.

[0039] It is understandable that after the clamping action is completed, when the photoelectric sensor 281 detects that there is a battery cell between the two clamping blocks 210, it is assumed that... The control system of the equipment controls the subsequent actions; when the photoelectric sensor 281 detects that there is no battery cell between the two clamps 210, the control system of the equipment issues an alarm signal, the equipment stops working, and notifies the operator through audible and visual alarms, thereby improving the safety of the equipment and products and avoiding batch product quality accidents.

[0040] In some preferred embodiments, side plates 270 are provided on both sides of the clamping block 210, and guide slopes are provided on the opposite side of the two side plates 270. The two side plates 270 are used to limit the two sides of the battery cell respectively.

[0041] Understandably, when the finger cylinder drives the two clamping blocks 210 to move closer to each other, a gradually narrowing guide channel is formed between the guide slopes of the two side plates 270, which can guide and correct the battery cell, ensuring that the battery cell is smoothly introduced into the predetermined clamping area between the two clamping blocks 210, thereby improving the clamping success rate.

[0042] Furthermore, anti-slip plates 290 are provided on opposite sides of the two clamping blocks 210. The surface of the anti-slip plates 290 is provided with anti-slip texture, thereby increasing the friction between the clamping blocks 210 and the battery cell, preventing the battery cell from falling off, and improving the stability of clamping.

[0043] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
