Description

Technical Field

[0001] This utility model relates to the field of lithium battery testing technology, and more specifically, it relates to a feeding device for lithium battery testing. Background Technology

[0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. With the continuous development of modern new energy vehicles and the new energy industry, the demand for lithium batteries is increasing. After the lithium battery is produced, it needs to be tested. Only after passing the test will it enter the market. In order to reduce the need for manual feeding and testing, a feeding device for lithium battery testing is proposed.

[0003] A search revealed that Chinese utility model patent application number CN202322045879.9 discloses a feeding device for lithium battery testing, including a main support frame and a main motor. The main motor is mounted on the top of the main support frame, and a threaded rod is mounted on the output end of the main motor. A threaded sleeve is fitted on the surface of the threaded rod and is slidably connected to the main support frame. A lower slide rail is symmetrically mounted on one end of the threaded sleeve, and a material support plate is mounted on the top of the lower slide rail and is slidably connected to the lower slide rail. An upper support plate is mounted on the top of the main support frame on one side of the main motor and is fixedly connected to the main support frame. An auxiliary motor is mounted on the top of the upper support plate.

[0004] In operation, the material support plate is first pulled out under the sliding engagement of the lower slide rail and the material support plate. The lithium battery is then placed on the material support plate, and the material support plate is reset. Next, the main motor is activated via the control panel, driving the threaded rod to rotate. The threaded rod then drives the threaded sleeve to move, which in turn drives the lower slide rail to move. The lower slide rail then drives the material support plate to move, and the material support plate drives the lithium battery upwards. For continuous feeding, the above operations are repeated. The upper cylinder is activated via the control panel, driving the vertical push rod downwards, which in turn drives the lower support plate downwards. The lower cylinder is activated via the control panel, driving the horizontal push rod to move, which in turn drives the gripper to move, clamping the lithium battery. The upper cylinder is deactivated via the control panel, lifting the lithium battery. The auxiliary motor is activated via the control panel, driving the gear to rotate. With the gear engagement of the rack and pinion mechanism, the rack moves, and with the sliding engagement of the upper slide rail and the slider, the rack drives the T-plate to move. The T-plate then drives the upper cylinder, lower support plate, lower cylinder, gripper, and lithium battery to move. After moving to the top of the testing platform, the gripper is released, and the lithium battery is placed on the testing platform. The control panel is used to reset the auxiliary motor to facilitate continuous reciprocating feeding of the lithium battery. The control panel is then used to activate the testing device to test the lithium battery. After testing, the control panel is used to activate the pusher cylinder, which drives the pusher arm to move, which in turn drives the pusher plate to move, which in turn drives the lithium battery to move to the next station. Repeating the above operations completes the testing of the next set of lithium batteries, thus completing the use of the feeding device for lithium battery testing. However, the feeding process for lithium batteries is complex and involves many steps, resulting in low feeding efficiency. Utility Model Content

[0017] Compared with the prior art, this utility model provides a feeding device for lithium battery testing, which has the following beneficial effects:

[0018] 1. Place the lithium battery in the placement slot on the conveyor table away from the fixed frame. The second motor drives the lithium battery threaded column to rotate clockwise. The clockwise rotation of the threaded column moves the convex seat and the conveyor table upward and to the top. Then, the first motor drives the rotating seat, vertical column, conveyor table and lithium battery to rotate, and rotate the lithium battery to the bottom of the detection device. Compared with the existing technology, the steps of feeding lithium batteries are reduced and the efficiency of feeding lithium batteries is improved.

[0019] 2.

[0030] Please see Figures 1-5A feeding device for lithium battery testing includes a base 1, a fixing frame 2 fixedly connected to the top of the base 1, a testing device 3 connected to the fixing frame 2 (the testing device 3 is existing equipment, and its structure and function will not be described in detail here), a control box 25 fixedly connected to the top of the base 1 (equipment required for lithium battery testing is installed inside the control box 25), and a control panel 26 connected to the control box 25 for controlling the operation of the electrical equipment on the device), a circular groove 4 provided at the top of the base 1, a rotating seat 5 rotatably connected inside the circular groove 4, a first motor 6 fixedly installed at the bottom of the base 1 to drive the rotating seat 5 to rotate, and a vertical [unclear - possibly a component or device] fixedly connected to the top of the rotating seat 5. The column 7 has two symmetrically arranged convex grooves 8. The interior of each convex groove 8 is slidably provided with a convex seat 9. Each convex seat 9 is threadedly connected with a threaded column 10. The threaded column 10 is rotatably connected to the column 7. The top of the column 7 is fixedly connected with a top cover 11. Two second motors 12 are fixedly installed on the top cover 11. The output ends of the two second motors 12 are fixedly connected to the top of the two threaded columns 10 respectively. Each side of the two convex seats 9 is fixedly connected with a conveyor table 13. Each conveyor table 13 is provided with a placement groove 14. The fixed frame 2 is fixedly connected with a support base 27, which supports the conveyor table 13 as it rotates to the bottom of the detection device 3.

[0031] Specifically, the lithium battery is placed inside the placement slot 14 on the conveyor table 13, which is away from the fixed frame 2. The second motor 12 drives the lithium battery threaded column 10 to rotate clockwise. The clockwise rotation of the threaded column 10 causes the convex seat 9 and the conveyor table 13 to move upward and to the uppermost side. Then, the first motor 6 drives the rotating seat 5, the vertical column 7, the conveyor table 13, and the lithium battery to rotate, so that the lithium battery is rotated to the bottom of the detection device 3. Compared with the prior art, the steps of loading lithium batteries are reduced, and the efficiency of loading lithium batteries is improved. During the detection of lithium batteries, the second motor 12, which is away from the fixed frame 2, drives the corresponding threaded column 10 to rotate counterclockwise, so that the conveyor table 13 moves to the lowermost side. Then, the lithium battery on the conveyor table 13 is removed, and the lithium battery to be tested is placed on the conveyor table 13. During the detection of lithium batteries, the lithium battery on another conveyor table 13 is replaced, which improves the efficiency of loading and testing lithium batteries.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5Each of the two conveyor tables 13 is fixedly connected to a fixing plate 15, and each of the two fixing plates 15 is fixedly connected to a first electric cylinder 16. A clamping plate 17 is fixedly connected to the telescopic end of the first electric cylinder 16. The bottom end of the clamping plate 17 contacts the bottom end of the placement groove 14, facilitating the clamping and fixing of the lithium battery. Two fixing rods 18 are fixedly connected to the side end of the clamping plate 17. The two fixing rods 18 are slidably engaged with the corresponding fixing plates 15 to ensure stable sliding of the clamping plate 17. The side end of the clamping plate 17 is fixedly connected to... Rubber pads 19 protect the lithium battery. Multiple slots 20 are evenly arranged on the outer side wall of the rotating base 5. An L-shaped plate 21 is fixedly connected to the side end of the base 1. A second electric cylinder 22 is fixedly connected to the L-shaped plate 21. A sliding plate 23 is slidably arranged on the L-shaped plate 21. The telescopic end of the second electric cylinder 22 is fixedly connected to the side end of the sliding plate 23. A locking post 24 that matches the slot 20 is fixedly connected to the other end of the sliding plate 23. The locking post 24 slides with the base 1 to facilitate the fixing of the rotating base 5.

[0033] Specifically, the first electric cylinder 16 pushes the clamping plate 17 to move, clamping and fixing the lithium battery. During the vertical transport of the lithium battery, this prevents the lithium battery from slipping. At the same time, the second electric cylinder 22 drives the slide plate 23 and the locking post 24 to move, so that the locking post 24 is inserted into the corresponding slot 20. This facilitates the fixing of the rotary table 5, the vertical column 7 and the two conveyor tables 13, improving the stability of the lithium battery during testing.

[0034] In summary, when using the overall equipment:

[0035] The lithium battery is placed inside the placement slot 14 on the conveyor table 13, which is away from the fixed frame 2. Then, two electric cylinders on the conveyor table 13 drive two clamping plates 17 to move, clamping and fixing the lithium battery. The second motor 12 drives the lithium battery threaded post 10 to rotate clockwise. The clockwise rotation of the threaded post 10 moves the convex seat 9 and the conveyor table 13 upwards to the uppermost position. After the lithium battery below the testing equipment has been tested, the second electric cylinder 22 pulls the slide plate 23 and the clamping post 24 to move, separating the clamping post 24 from the clamping slot 20. Then, the first motor 6 drives the rotating seat 5, the vertical column 7, the conveyor table 13, and the lithium battery to rotate. The device rotates the lithium battery to be tested to the bottom of the testing equipment. At this time, the bottom end of the conveyor table 13 contacts the top end of the support base 27. Then, the second electric cylinder 22 pushes the slide plate 23 and the clamping post 24 to move, so that the clamping post 24 is inserted into the inside of the clamping slot 20. While testing the lithium battery, the second motor 12, which is away from the fixed frame 2, drives the corresponding threaded post 10 to rotate counterclockwise, so that the conveyor table 13 moves to the bottom. Then, the first electric cylinder 16 pulls the clamping plate 17 to move away from the lithium battery. Then, the lithium battery on the conveyor table 13 is removed, and the lithium battery to be tested is placed on the conveyor table 13 for replacement.
