[0002] A battery cell clamp is a component used to secure battery cells.

[0003] Existing cell clamps are designed separately based on single-station loading. Currently, cell loading devices have been improved to dual-station systems; therefore, the structure of the cell clamps has also been modified accordingly, such as… Figure 1 As shown, Figure 1 This is the improved structure.

[0004] The improved battery cell clamps feature a symmetrical arrangement of single-row clamping elements. Consequently, the orientation of the battery cell's upper tabs has changed. Traditional voltage detection devices are unable to perform voltage detection on this type of battery cell based on the existing structure. Utility Model Content

[0029] Please see Figure 2-13 As shown, Figure 2 A perspective view of the present invention is shown.

[0030] This utility model includes the following workstations arranged on a machine frame in sequence:

[0031] Loading station, transport station, inspection station, unloading station;

[0032] The loading station is used to transport the pallet to the transport station. The loading station includes a first pallet 1, a fifth linear moving mechanism, and a robot arm 3 that moves the battery cell clamp 2. The first pallet 1 is set on the output end of the fifth linear moving mechanism. The movement path of the robot arm 3 includes the highest position of the first pallet 1. The robot arm 3 clamps the battery cell clamp 2 at the highest position of the first pallet 1 and moves the battery cell clamp 2 to the transport station.

[0033] The transport station includes a transport component, and the testing station includes a first linear moving mechanism 41 and a positioning mechanism 42 arranged opposite to each other with the transport component as the center. The cell clamp 2 is located on the transport component and between the positioning mechanism 42 and the first linear moving mechanism 41. The positioning mechanism 42 has a positioning end that can constrain the movement of the positioning clamp. The movable end of the first linear moving mechanism 41 is provided with a plurality of staggered test pins 43. The arrangement direction of the test pins 43 corresponds to the single row of cells on the cell clamp 2. The output end of the first linear moving mechanism 41 has a direction of movement towards each row of cells. Thus, by using a plurality of staggered test pins 43, the symmetrical arrangement between cells can be satisfied. The test pins 43 are located on the output end of the first linear moving mechanism 41. According to the direction of movement of the output end of the first linear moving mechanism 41, the test pins 43 move between different rows of cells to test the voltage of each row of symmetrically arranged cells.

[0034] In other words, this invention solves the problem that existing equipment cannot detect battery cells in a symmetrical layout.

[0035] The feeding mechanism includes a feeding mechanism for removing battery cells from the battery cell clamp 2, and a storage component for distributing and storing good and defective products.

[0036] The material handling mechanism 5 includes a third linear moving mechanism, a rotary table 52, an opening component 53, a third telescopic cylinder 54, and multiple suction nozzles 56 disposed on a first mounting plate 55. The rotary table 52 is disposed at the output end of the third linear moving mechanism, the opening component 53 is disposed at the output end of the rotary table 52, and the third telescopic cylinder 54 is disposed at the output end of the opening component 53. The opening component 53 has a direction for pushing the third telescopic cylinder 54 outward. The first mounting plate 55 is connected to the output end of the third telescopic cylinder 54, and the third telescopic cylinder 54 has a way of moving towards the battery cell clamp 2. This solution is used to remove the battery cell from the battery cell clamp 2. The battery cell clamp 2 includes a clamping member 21. Therefore, it is necessary to open the clamping member 21 to loosen the fixation of the battery cell. At the same time, the battery cell is moved away from the clamping area of ​​the clamping member 21. The opening component 53 pushes the position of the suction nozzles 56 outward, so that after the suction nozzles 56 adsorb the battery cell, they remove the battery cell from the clamping area.

[0037] The storage mechanism includes three sets of second pallets and a fourth linear moving mechanism. The second pallets are equipped with cell trays for storing battery cells. The output end of the second linear moving mechanism is connected to the second pallet. The picking mechanism 5 directly places the picked-up battery cells into the cell trays.

[0038] The storage mechanism has three groups: the first group 61 is used to store good quality battery cells, the second group 62 is used to store defective battery cells, and the third group 63 is used to store the battery cell clamp 2.

[0039] The transport assembly also includes a limiting bar 71 and a fifth telescopic cylinder 72 positioned above the third group 63 storage mechanism. The limiting bar 71 is a set, with space reserved between the limiting bars 71 for the passage of the battery cell clamp 2. On the opposite sides of the limiting bars 71, there are grooves 71a to support the passage of the battery cell clamp 2. The output end of the fifth telescopic cylinder is connected to the limiting bar 71. This is a choice based on the design of the battery cell clamp 2. The second tray is for lifting and lowering. The two ends of the battery cell clamp 2 are located in the grooves 71a. When the previous inspection process is completed, in order to quickly retract the battery cell clamp 2, the fifth telescopic cylinder retracts the piston rod to pull the positions of the two limiting bars 71 apart, and the battery cell clamp 2 will automatically fall into the second tray.

[0040] Furthermore, the positioning mechanism 42 includes a second linear moving mechanism, a pressure plate 42a, an adjusting plate 42b, a guide roller 42c, and a first telescopic cylinder 42d. The output end of the second linear moving mechanism is connected to the adjusting plate 42b, and the adjusting plate 42b is provided with a guide sleeve 42e. The output end of the first telescopic cylinder 42d is connected to the pressure plate 42a. The guide roller 42c is connected to the pressure plate 42a through the guide sleeve 42e. The pressure plate 42a is provided with multiple openings corresponding to the clamping member 21. The purpose is to fix the position of the battery cell clamp 2 on the transport assembly to ensure that the battery cell clamp 2 will not move during testing. In addition, the test pin 43 passes through the battery cell clamp 2 from below and contacts the battery cell for testing. Therefore, the specific implementation of the positioning mechanism 42 is to apply a frontal pressure to the battery cell so that the battery cell cannot be lifted.

[0041] Furthermore, the positioning post 42f on the pressure plate 42a corresponds to the positioning hole 22 on the cell clamp 2; the design of the positioning post 42f is to further enhance the stability of the cell clamp 2.

[0042] Furthermore, it also includes a needle plate 44 and a second telescopic cylinder 45. The test pin 43 is set on the needle plate 44, and the second telescopic cylinder 45 is set on the output end of the first linear movement mechanism 41. The output end of the second telescopic cylinder 45 is connected to the needle plate 44. During the test, the second telescopic cylinder 45 plays a pushing effect to ensure that the test pin 43 is in stable contact with the battery cell.

[0043] Furthermore, the transport component includes a first roller 74 and a second roller 73 located below the positioning mechanism 42. The tangential directions of the first roller 74 and the second roller 73 are perpendicular to each other. The first roller 74 is vertically arranged, which can both position the battery cell clamp 2 and ensure the smooth movement of the battery cell clamp 2. The second roller 73 is horizontally arranged to avoid interference between the second roller 73 and the positioning mechanism 42.

[0044] Furthermore, the open assembly 53 includes a fourth telescopic cylinder 53a, a push plate 53b, and a sliding assembly 53c. A first mounting plate 55 is disposed on the movable end of the sliding assembly 53c. The movable end of the sliding assembly 53c is provided with an inclined guide port 53c-1. The push plate 53b is provided with a mounting roller 53d for inserting into the guide port 53c-1. A bearing is sleeved on the mounting roller 53d, and the bearing abuts against the inner surface of the guide port 53c-1. The output end of the fourth telescopic cylinder 53a is connected to the push plate 53b. This method of using the open assembly 53 mainly uses a small amount of power source to control multiple suction nozzles 56 to move outward simultaneously. It has a simple structure and strong practicality.
