Technical Field

[0001] The utility model relates to the technical field of abnormality detection of battery slices, in particular to a phosphorus diffusion abnormality detection device for battery slice production. Background Art

[0002] Phosphorus diffusion is a diffusion method that introduces phosphorus ions into silicon crystals. Specifically, phosphorus diffusion is done by placing the silicon crystal in a high-temperature furnace and then adding phosphates to diffuse the phosphorus ions to the surface of the crystal and form a P-type silicon layer with a thickness of several microns on the surface.

[0003] However, during the abnormal phosphorus expansion detection of battery cells, the battery cells are directly placed on the transmission belt for transmission for abnormal phosphorus expansion detection. In this way, the battery cells may be accidentally touched during the transmission process, resulting in the impact of abnormal phosphorus expansion detection of the battery cells. At the same time, when distinguishing between abnormal and normal battery cells, the distinction is usually made through a robot arm, which has a high cost for the robot and is also troublesome for later maintenance.

[0004] In view of the above problems, the inventors propose a phosphorus diffusion abnormality detection device for battery cell production to solve the above problems. Utility Model Content

[0022] By adopting the above technical solution, when the double-headed threaded rod 33 rotates, it drives the moving block 34, the second fixed plate 35, and the L-shaped fixed block 36 to move. At the same time, the battery cell is directly placed on the placement groove 38 through the placement groove 38, so that the battery cells of different lengths can be tested for abnormal phosphorus diffusion, avoiding accidental contact with the battery cell and affecting the abnormal phosphorus diffusion detection of the battery cell.

[0023] A support platform 41 is fixedly installed on the upper surface of the base 1 through four second supporting legs, a material discharge chute 42 is opened through the middle of the support platform 41, two symmetrically distributed slides 51 are fixedly installed on one side of the support platform 41, a connecting strip 52 is fixedly installed at the top edge of the slide 51, a second fixed block 53 is fixedly installed at the bottom end of the connecting strip 52, an electric telescopic rod 54 is fixedly installed at the bottom of the second fixed block 53, a second clamping block 55 is fixedly installed at the driving end of the electric telescopic rod 54, an inclined plate 56 is fixedly installed on the top of the second clamping block 55, and the inclined plate 56 is slidably clamped on the slide 51, and a collection box 6 is placed below the material discharge chute 42 and the inclined plate 56.

[0024] By adopting the above technical solution, when abnormal expansion of a battery cell is detected, the electric telescopic rod 54 is started to drive the second clamping block 55 and the inclined plate 56 to move in the direction of the lower material chute 42 to block the lower material chute 42, and the abnormal battery cell falls directly onto the inclined plate 56, and then the electric telescopic rod 54 drives the second clamping block 55, the inclined plate 56 and the battery cell on the inclined plate 56 to shrink back, and finally the abnormal battery cell falls into the collection box 6 under the action of the inclined plate 56, so that the abnormal and non-abnormal battery cells can be distinguished without using a robot, which reduces costs and facilitates later maintenance.

[0025] The base 1 is located between the support platform 41 and the first fixing seat 11 and is fixedly mounted with an inclined block 4 via four third supporting legs.

[0026] By adopting the above technical solution, it is convenient for the battery cells to fall into the discharge chute 42 .

[0027] A gear 17 is fixedly mounted on the outside of one of the first rotating shafts 12 , a second rotating shaft 18 is rotatably inserted on one side of one of the first fixing seats 11 close to the gear 17 , and a half-face gear 19 corresponding to the gear 17 is fixedly mounted on the outside of the second rotating shaft 18 .

[0028] By adopting the above technical solution, when the half-gear 19 is engaged with the gear 17, the first rotating shaft 12 is driven to rotate, thereby driving the pulley 13 and the transmission belt 14 to rotate. The pulley 13 and the transmission belt 14 are used in conjunction to drive the first fixed plate 15 to rotate, thereby driving the components and battery cells on the first fixed plate 15 to be transmitted. When the half-gear 19 is not engaged with the gear 17, the first rotating shaft 12, the pulley 13, the transmission belt 14, the first fixed plate 15, the components and battery cells on the first fixed plate 15 stop transmitting. At the same time, the battery cells are located in the detector 2, and the battery cells are detected for abnormal phosphorus diffusion. While detecting, the undetected battery cells are placed on the placement slot 38 for transmission and detection.

[0029] A limiting rod 39 is fixedly installed between the two first fixed blocks 32 , and the two moving blocks 34 are slidably sleeved on the limiting rod 39 .

[0030] By adopting the above technical solution, the moving block 34 is limited by the limiting rod 39 to prevent it from rotating along with the rotation of the double-threaded rod 33 .

[0031] A slot 43 corresponding to the inclined plate 56 is formed on one side of the support platform 41 , and a slot 44 corresponding to the second locking block 55 is formed on one side of the support platform 41 close to the slot 43 .

[0032] By adopting the above technical solution, the sliding of the second clamping block 55 and the inclined plate 56 is facilitated.

[0033] The top edge of the material discharge chute 42 is in contact with the inclined block 4 .

[0034] By adopting the above technical solution, it is convenient for the detected battery cells to fall from the discharge chute 42 into the corresponding collection box 6 .

[0035] The second fixing seats 5 are fixedly mounted on the opposite outer sides of the two sliding seats 51 , and the bottom ends of the second fixing seats 5 are fixedly mounted on the base 1 .

[0036] By adopting the above technical solution, the slide seat 51 is supported, so that the inclined plate 56 is more stable when sliding on the slide seat 51.

[0037] Working principle: When in use, firstly, according to the length of the battery cell, rotate the rotating wheel on the double-threaded rod 33, so that the rotating wheel drives the double-threaded rod 33 to rotate, thereby driving the moving block 34, the second fixed plate 35, and the L-shaped fixed block 36 to move. After adjustment, the battery cell is placed on the placement groove 38, and then the motor is started to drive the second rotating shaft 18 to rotate, thereby driving the half-face gear 19 to rotate, so that the half-face gear 19 is meshed with the gear 17, driving the gear 17 to rotate, thereby driving the first rotating shaft 12 to rotate, and the rotation of the first rotating shaft 12 drives the two adjacent pulleys 13 to rotate, and then the pulley 13 drives the other two adjacent pulleys 13 to rotate through the transmission belt 14. The pulley 13 and the transmission belt 14 are used in combination to drive the first fixed plate 15 and the components on the first fixed plate 15 and the battery cell to be transmitted;

[0038] When the half-face gear 19 is not meshed with the gear 17, the first rotating shaft 12, the pulley 13, the transmission belt 14, the first fixing plate 15, the components on the first fixing plate 15 and the battery cells stop being transported. Meanwhile, the battery cells are placed in the detector 2, and abnormal phosphorus diffusion is detected on the battery cells. During the detection, the undetected battery cells are placed on the placement slot 38, and are transported again for detection.

[0039] When conveying again, the normal battery cells are detected to slide down from the inclined block 4 into the discharge chute 42 under the action of the transmission belt 14, and finally fall from the discharge chute 42 into the collection box 6 below the discharge chute 42. Then, when abnormal battery cells are detected, the electric telescopic rod 54 is started to drive the second block 55 and the inclined plate 56 to move in the direction of the lower chute 42 to block the lower chute 42. The abnormal battery cells fall directly onto the inclined plate 56, and then the second block 55, the inclined plate 56 and the battery cells on the inclined plate 56 are driven back by the electric telescopic rod 54. Finally, the abnormal battery cells fall into the collection box 6 below the inclined plate 56 under the action of the inclined plate 56.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
