Detailed implementation manners

[0030] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0031] Example 1, as Figure 1-2 shown, a shearing performance tester for a lithium battery pruning shear includes four support legs 1. The upper ends of the four support legs 1 are fixedly connected to a working mechanism 2 together. A fixing mechanism 3 is arranged on the left side of the working mechanism 2, a testing mechanism 4 is arranged on the right side of the working mechanism 2, a control center 5 is arranged at the front part on the right side of the working mechanism 2, a second motor 6 is arranged at the lower part on the right side of the working mechanism 2, and the output end of the second motor 6 is fixedly connected to a second gear disk 7. The outer surface of the second gear disk 7 is meshed with the lower side of the testing mechanism 4.

[0032] It should be noted that the specific installation method, connection method of the circuit, and control method of the control center 5 and the second motor 6 in the present invention are all conventional designs and are the conventional design means of designers. The control center 5 is composed of components such as a controller, a display, a power supply, and a switch, and the second motor 6 is controlled by the control center 5.

[0033] First, prepare the lithium battery pruning shears to be tested. Then, according to the actual test requirements, fix lithium battery pruning shears of different models through the fixing mechanism 3. After being fixed, they are transported in the direction of the testing mechanism 4 by the fixing mechanism 3. When the lithium battery pruning shears are transported to the right by the fixing mechanism 3, the testing mechanism 4 is adjusted with the cooperation of the working mechanism 2. Then, the fixing mechanism 3 controls the lithium battery pruning shears to cut the testing mechanism 4. In addition, by starting the second motor 6 to drive the testing mechanism 4 to rotate and adjust through the second gear disc 7, the actual cutting diameters of different types of lithium battery pruning shears can be tested. At the same time, the specific situation of the cutting surface is fed back to the control center 5 by the testing mechanism 4, and the cutting effect can be seen intuitively and clearly through the control center 5.

[0034] In order to assist the fixing mechanism 3 and the testing mechanism 4 to complete the shearing performance test of the lithium battery pruning shears, as Figure 3 shown, the working mechanism 2 includes a workbench 21. A round hole 22 is opened in the middle of the upper end of the right side of the workbench 21. A first sliding groove 28 is opened in the middle of the upper end of the workbench 21. A first motor 27 is fixedly connected to the left side of the lower end of the workbench 21. Two first supports 25 are fixedly connected to the left side of the lower end of the workbench 21. A first threaded rod 24 is rotatably connected in the common inner cavity of the two first supports 25. The left end of the first threaded rod 24 and the output end of the first motor 27 are both fixedly connected with a first transmission wheel 26. The two first transmission wheels 26 are connected by a belt. A lifting group 23 is fixedly connected to the middle of the lower end of the workbench 21. The upper end of the right side of the workbench 21 is fixedly connected to the upper end of the second motor 6. The upper ends of the four support legs 1 are jointly fixedly connected to the lower end of the workbench 21.

[0035] It should be noted that the specific installation method, connection method of the circuit, and control method of the first motor 27 in the present invention are all conventional designs and are the conventional design means of designers, and the first motor 27 is controlled by the control center 5.

[0036] First, install the fixing mechanism 3 through the sliding groove 1-28 and the threaded rod 1-24, install the testing mechanism 4 through the workbench 21 and the round hole 22. Then, install the lithium battery pruning shear to be tested into the fixing mechanism 3. Next, control the motor 1-27 to rotate through the control center 5. With the cooperation of the two driving wheels 1-26 and the belt, the threaded rod 1-24 rotates in the inner cavities of the two supports 1-25. Through the rotation of the threaded rod 1-24, the fixing mechanism 3 slides to the right in the inner cavity of the sliding groove 1-28. When the fixing mechanism 3 moves to the right, it compresses the lifting group 23, enabling the lifting group 23 to adjust the testing mechanism 4 upward. At this time, the fixing mechanism 3 controls the lithium battery pruning shear to cut the testing mechanism 4, achieving the purpose of assisting the fixing mechanism 3 and the testing mechanism 4 to complete the shearing performance test of the lithium battery pruning shear. In addition, after the cutting is completed, the threaded rod 1-24 drives the fixing mechanism 3 to slide to the left in the inner cavity of the sliding groove 1-28, and the testing mechanism 4 and the lifting group 23 return to their initial states.

[0037] Further explanation: As shown in Figure 4 and Figure 5 the lifting group 23 includes a housing 231. The upper end of the housing 231 is fixedly connected to the middle part of the lower end of the workbench 21. A first gear disk 233 is rotatably connected to the middle part of the inner cavity of the housing 231. A rack 232 is slidably connected to the right side of the inner cavity of the lifting group 23. The lower end of the rack 232 is fixedly connected to an L-shaped pull rod 234. A toothed plate 236 is slidably connected to the left side of the inner cavity of the housing 231. The left side of the rack 232 and the right side of the toothed plate 236 are jointly meshed with the first gear disk 233. A rotating rod 235 is rotatably connected to the lower side of the inner cavity of the toothed plate 236. An elastic sheet 238 is fixedly connected to the upper side of the inner cavity of the toothed plate 236. A traction rope 237 is fixedly connected to the upper side of the inner cavity of the toothed plate 236, and the traction rope 237 is located directly below the elastic sheet 238. The left end of the traction rope 237 is fixedly connected to the upper side of the rotating rod 235.

[0038] Specifically, during the process of the threaded rod 1 driving the fixing mechanism 3 to move to the right in the inner cavity of the first sliding groove 28, the lower side of the fixing mechanism 3 presses down the rotating rod 235. While the rotating rod 235 rotates towards the toothed plate 236, the toothed plate 236 moves vertically downward, thereby driving the first toothed disc 233 to rotate. Through the rotation of the first toothed disc 233, the rack 232 drives the L-shaped pull rod 234 to move vertically upward, thereby driving the testing mechanism 4 to move upward. When the rotating rod 235 rotates to compress the elastic sheet 238 in the inner cavity of the toothed plate 236, the fixing mechanism 3 moves to the rightmost side in the inner cavity of the first sliding groove 28 and stops moving. At this time, the fixing mechanism 3 controls the lithium battery pruning shear to cut the testing mechanism 4, completing the testing work. After the cutting is completed, the fixing mechanism 3 moves to the left. Under the elastic force of the elastic sheet 238, the rotating rod 235 pops out of the inner cavity of the toothed plate 236 and rotates to the left to return to the initial state. By installing the traction rope 237, when the fixing mechanism 3 moves to the right, the rotating rod 235 can be compressed.

[0039] Embodiment 2. On the basis of Embodiment 1, this embodiment realizes the purpose of fixing different types of lithium battery pruning shears. As Figure 6 shown, the fixing mechanism 3 includes a threaded slider 32. A groove 33 is opened at the lower right end of the threaded slider 32. A convex slide plate 31 is fixedly connected to the upper end of the threaded slider 32. The middle part of the bottom wall of the inner cavity of the convex slide plate 31 is fixedly connected with a cushion block 34. A screw rod component 36 is rotatably connected to the middle parts of the inner cavity of the cushion block 34 and the inner cavity of the convex slide plate 31. Slide seats 35 are meshed and connected to the left and right sides of the outer surface of the screw rod component 36. Clamping plates 38 are rotatably connected to the upper sides of the two slide seats 35. A knob component 37 is rotatably connected to the upper middle part of the front end of the convex slide plate 31. A stretching group 39 is fixedly connected to the upper side of the rear end of the convex slide plate 31. The front side of the outer surface of the screw rod component 36 is connected to the knob component 37 through a belt. The lower side of the outer surface of the convex slide plate 31 is slidably connected to the inner cavity of the first sliding groove 28.

[0040] It should be noted that the screw component 36 is composed of a screw and a pulley, the knob component 37 is composed of a knob and a pulley, and the pulley in the screw component 36 is connected to the pulley in the knob component 37 by a belt. The cushion block 34 is composed of a rectangular block and a slide rail. First, place the lithium battery pruning shear to be tested on the inner cavity of the convex slide plate 31 and the cushion block 34. Then, rotate the knob component 37, and with the cooperation of the belt, drive the screw component 36 to rotate. Through the rotation of the screw component 36, drive the two slide seats 35 to move away from or close to each other on the slide rails in the cushion block 34 until the clamping plates 38 on the two slide seats 35 respectively fix different types of lithium battery pruning shears to be tested. Next, drive the transmission wheel one 26 through the motor one 27, and with the cooperation of the belt, make the threaded slider 32 slide on the outer surface of the threaded rod one 24 while driving the convex slide plate 31 to move to the right in the inner cavity of the slide groove one 28. During the movement, the inner cavity of the groove 33 will be stuck on the upper side of the rotating rod 235 and compress the rotating rod 235. With the cooperation of the gear disk one 233, the rack 232 and the L-shaped pull rod 234, make the testing mechanism 4 move upward. Finally, start the lithium battery pruning shear through the stretching group 39 to perform a shearing operation on the testing mechanism 4, achieving the purpose of fixing different types of lithium battery pruning shears.

[0041] Further illustration, as Figure 7 shown, the stretching group 39 includes two supports two 391. A threaded rod two 392 is rotatably connected to the common inner cavities of the two supports two 391. A rotating seat 393 is meshed and connected to the outer surface on the right side of the threaded rod two 392. The middle part of the upper end of the rotating seat 393 is rotatably connected to an electric telescopic rod 394. A pressure plate 395 is fixedly connected to the front side of the outer surface of the electric telescopic rod 394. The front ends of the two supports two 391 are fixedly connected to the upper side of the rear end of the convex slide plate 31 together.

[0042] It should be noted that the specific installation method, the connection method of the circuit, and the control method of the electric telescopic rod 394 and the pressure plate 395 in the present invention are all conventional designs, which are the conventional design means of designers. Among them, the pressure plate 395 is composed of a clamping plate and a pressure sensor. The electric telescopic rod 394 and the pressure sensor in the pressure plate 395 are both controlled by the control center 5.

[0043] Specifically, after the two clamping plates 38 fix the lithium - battery pruning shears, then rotate the second threaded rod 392, so that the rotating seat 393 moves left and right on the outer surface of the second threaded rod 392. Adjust according to the switch buttons on different types of lithium - battery pruning shears to the appropriate position. When it is necessary for the lithium - battery pruning shears to shear the test mechanism 4, the electric telescopic rod 394 contracts, driving the pressure plate 395 to press the switch button on the lithium - battery pruning shears, starting the lithium - battery pruning shears to shear the test mechanism 4. At the same time, the pressure plate 395 will record the felt pressure and feedback it to the control center 5. In addition, the vibration generated when the lithium - battery pruning shears shear the test mechanism 4 will also be fed back to the control center 5.

[0044] Embodiment 3. On the basis of Embodiment 1 and Embodiment 2, this embodiment cooperates with the fixing mechanism 3 to complete the purpose of shearing test of the lithium - battery pruning shears. As Figure 8 and Figure 9 shown, the test mechanism 4 includes a rotating sleeve 41. A turntable 43 is rotatably connected to the inner cavity of the rotating sleeve 41. A plurality of through - holes 44 are annularly arranged at the upper end of the turntable 43. A cutting column 45 is arranged in each of the plurality of through - holes 44. A rotating group 42 is jointly provided at the lower sides of the plurality of cutting columns 45 and the lower end of the rotating sleeve 41. A photographing component 46 is fixedly connected to the middle of the rotating group 42. The upper end of the rotating sleeve 41 is fixedly connected to the middle of the lower end of the workbench 21.

[0045] It should be noted that the specific installation method, circuit connection method and control method of the photographing component 46 in the present invention are all conventional designs, which are the conventional design means of designers. The photographing component 46 is composed of a telescopic rod and a small camera, and is controlled by the control center 5. In addition, the plurality of through - holes 44 correspond to the plurality of cutting columns 45 one by one, and the plurality of cutting columns 45 are made of branches with different diameters.

[0046] When the control center 5 controls the second motor 6 to drive the second gear disk 7 to rotate and adjust the rotating group 42, with the cooperation of the plurality of cutting columns 45, the turntable 43 will be driven to rotate in the inner cavity of the rotating sleeve 41, so that the cutting columns 45 with different diameters rotate to the appropriate positions according to the actual shearing requirements. When the rack 232 drives the L - shaped pull rod 234 to move upward, the rotating group 42 and one of the cutting columns 45 are driven to move upward to the appropriate positions. The lithium - battery pruning shears are used to shear the cutting column 45. After the shearing is completed, the photographing component 46 takes a picture of the shearing plane on the cutting column 45 and feeds it back to the control center 5 to observe the flatness of the shearing. By operating like this, until the actual maximum shearing diameter of the lithium - battery pruning shears is detected, finally the shearing test work of different types of lithium - battery pruning shears is realized, and the upper - layer waste after shearing can be discharged through the inner cavity of the turntable 43.

[0047] Further explanation, as Figure 10As shown, the rotating group 42 includes a connecting frame 421. At the upper end of the connecting frame 421 in the horizontal direction, a pulley ring 423 is fixedly connected. A rotating gear ring 422 is rotatably connected to the outer surface of the pulley ring 423. A number of positioning columns 424 are annularly arranged at the upper end of the rotating gear ring 422. A mounting seat 425 is slidably connected to the outer surface of each of the number of positioning columns 424. A clamping groove 426 is fixedly connected to the outer surface of each of the number of mounting seats 425. A circular groove 427 is opened at the upper end of each of the number of mounting seats 425. The lower sides of the outer surfaces of a number of cutting columns 45 are respectively slidably connected to the inner cavities of the number of circular grooves 427. The lower end of the photographing component 46 is fixedly connected to the middle of the upper end of the connecting frame 421 in the horizontal direction.

[0048] Specifically, the circular grooves 427 opened on a number of mounting seats 425 correspond one-to-one to a number of cutting columns 45, and each of the mounting seats 425 is slidably connected up and down. When the rotating rod 235 drives the toothed plate 236 to slide downward, the first toothed disc 233 rotates, thereby driving the rack 232 and the L-shaped pull rod 234, so that the L-shaped pull rod 234 drives the adjacent clamping groove 426 to move upward. Through the cooperation of the clamping groove 426 and the mounting seat 425, the cutting column 45 in the circular groove 427 is driven to move upward in the inner cavity of the through hole 44. The lithium battery pruning shear shears the cutting column 45. After the shearing is completed, the threaded slider 32 drives the convex-shaped sliding plate 31 to move to the left in the inner cavity of the first sliding groove 28, and the groove 33 no longer compresses the rotating rod 235. Under the gravity of the mounting seat 425, the cutting column 45, the rack 232 and the L-shaped pull rod 234, the first toothed disc 233 rotates in the reverse direction, so that the toothed plate 236 drives the rotating rod 235 to move upward to restore the initial state, and the mounting seat 425 and the cutting column 45 also restore the initial state. Then, by starting the second motor 6 to drive the second toothed disc 7, the rotating gear ring 422 is rotated on the outer surface of the pulley ring 423 to a suitable position, so that the new cutting column 45 rotates to the position of the cut cutting column 45, and is ready to move upward for shearing until the maximum shearing diameter of the lithium battery pruning shear is detected. Moreover, due to the design of driving the cutting column 45 to slide up and down by the mounting seat 425, other cutting columns 45 will not affect the shearing test of the lithium battery pruning shear. In addition, the vibration generated when the lithium battery pruning shear shears the cutting columns 45 with different diameters will be fed back to the control center 5 by the pressure plate 395. And through the cooperation of the pressure generated by the pressure plate 395 pressing the switch button of the lithium battery pruning shear and the control center 5, and the control center 5 displays the pressure induction time of the pressure plate 395, the shearing time of the lithium battery pruning shear on the cutting column 45 is displayed, and together with the flatness of the plane of the cut cutting column 45, the shearing performance of the lithium battery pruning shear is measured.

[0049] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention.
