Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an automatic terminal grinding device. Background Technology

[0002] Currently, in the battery production process, the grinding of the terminals is crucial. Most of the produced batteries will undergo storage, which will cause the terminals to oxidize and form an oxide layer on the surface. Therefore, the oxide layer needs to be ground off when leaving the factory.

[0003] Traditionally, grinding the external parts of battery terminals requires manual hand-held tools, so terminal grinding cannot be automated, resulting in low production efficiency and high labor costs.

[0004] Meanwhile, the automatic grinding device is inconvenient to replace the grinding brush during long-term operation, which affects production efficiency and results in poor practical performance of the automatic grinding device.

[0005] To address this issue, this utility model proposes an automatic grinding device for the pole posts. Utility Model Content

[0007] Therefore, the purpose of this utility model is to propose an automatic grinding device for poles, including a grinding device frame and a conveying mechanism. The grinding device frame is provided with two automatic grinding mechanisms. Each of the two automatic grinding mechanisms includes several fixed seats fixedly connected to one side of the grinding device frame. Two guide shafts are fixedly connected inside the several fixed seats. An upper slider and two lower sliders are slidably connected to the outside of the two guide shafts. A lifting frame is fixedly connected to both sides of the upper slider and the two lower sliders.

[0008] The top of the lifting frame is fixedly connected to several mounting seats. The interior of each mounting seat is fixedly connected to two sliding rods. The exterior of each sliding rod is slidably connected to four adjusting blocks. The top of each of the four adjusting blocks is fixedly connected to a support platform.

[0009] A positioning cylinder is fixedly connected to the bottom of the support platform, and a rotating shaft is rotatably connected inside the support platform. The outside of the rotating shaft is rotatably connected to the inside of the positioning cylinder. An installation cylinder is provided outside the rotating shaft, and two fixing screws are threadedly connected to the inside of the installation cylinder and the rotating shaft.

[0010] A grinding rotating block is fixedly connected to the bottom of the mounting cylinder. Four disassembly blocks are provided inside the grinding rotating block. Several mounting screws are threadedly connected to the four disassembly blocks and the grinding rotating block. A grinding brush is fixedly connected inside the disassembly block.

[0011] Preferably, in any of the above embodiments, a rotating motor is fixedly connected to the top of the support platform, and the output end of the rotating motor is fixedly connected to the top of the rotating shaft.

[0012] The technical effect achieved by adopting the above solution is that the output end of the rotating motor drives the rotating shaft to rotate inside the bearing platform and the positioning cylinder.

[0013] Preferably, in any of the above embodiments, two adjusting plates are fixedly connected to the bottom of the support platform, and positioning plates are fixedly connected to both sides of the lifting frame, with adjusting screws rotatably connected inside the positioning plates.

[0016] The technical effect achieved by adopting the above solution is that the output end of the motor drives the lifting screw to rotate, so that the upper slide block rises and falls along the lifting screw.

[0017] Preferably, in any of the above embodiments, the conveying mechanism includes a conveying equipment body, the bottom of which is fixedly connected to one side of the grinding device frame, and two positioning frames are provided on the top of the conveying equipment body.

[0023] 1. The grinding brush is rotated by the grinding rotating block to grind the oxide layer on the outside of the battery terminals. At the same time, the battery is transported by the conveying mechanism, which realizes the effect of automating the grinding of the battery terminals. This solves the problem that the grinding of the battery terminals still requires manual hand tools when grinding the outside of the battery terminals in the traditional way. In this way, the production efficiency is improved and the labor cost is reduced through automation.

[0024] 2. When the grinding brush needs to be replaced, the disassembly block is removed and installed from the grinding rotating block to replace the grinding brush. This avoids the inconvenience of replacing the grinding brush and affects production efficiency. It solves the problem that it is inconvenient to replace the grinding brush when the automatic grinding device is working for a long time, and helps to improve the practical performance of the automatic grinding device.

[0037] Example 1: As Figures 1 to 8 As shown, the automatic terminal grinding device includes a grinding device frame 1 and a conveying mechanism 2. A glass window is provided on the outside of the grinding device frame 1, allowing for relative enclosure of the grinding device. Space is needed at the conveying mechanism 2 to ensure proper battery transport, thus protecting the normal operation of the grinding device. Two automatic grinding mechanisms are installed inside the grinding device frame 1. The two mechanisms operate on the same principle and have the same structure. It should be noted that two automatic grinding mechanisms are used because the distance between the two battery terminals and the volume of the two rotating motors are mismatched, making it impossible to set a suitable spacing so that the two grinding rotating blocks 23 correspond exactly to the two terminals. There are multiple terminals, and the spacing between different battery terminals is also different. Therefore, two automatic grinding mechanisms are set here. Each automatic grinding mechanism includes several fixed seats 3 fixedly connected to one side of the grinding device frame 1. The fixed seats 3 are fixed to the grinding device frame 1 by bolts to connect and fix the guide shaft 4. Two guide shafts 4 are fixedly connected inside the several fixed seats 3. The upper slider 5 and two lower sliders 6 are slidably connected to the outside of the two guide shafts 4. Lifting frames 7 are fixedly connected to both sides of the upper slider 5 and the two lower sliders 6. When the upper slider 5 rises and falls, it will drive the lifting frame 7 to rise and fall. At the same time, the lifting frame 7 will drive the support platform 14 and grinding rotating block 23 and other components to rise and fall.

[0038] The top of the lifting frame 7 is fixedly connected to several mounting seats 11. The inside of the mounting seat 11 is fixedly connected to two slide rods 12. The outside of the slide rods 12 is slidably connected to four adjusting blocks 13. The top of the four adjusting blocks 13 is fixedly connected to a support platform 14. When adjusting, the four adjusting blocks 13 will slide along the outside of the two slide rods 12, thereby driving the support platform 14 to adjust its position. At the same time, the position of the grinding rotating block 23 is also adjusted. This adjustment is not the adjustment when grinding the battery terminal, but the adjustment when installing or adjusting the equipment. Then, when the automatic grinding device is working, the position of the support platform 14 is fixed in the set position.

[0039] A positioning cylinder 19 is fixedly connected to the bottom of the base 14. A rotating shaft 20 is rotatably connected inside the base 14. The outside of the rotating shaft 20 is rotatably connected to the inside of the positioning cylinder 19. An installation cylinder 21 is provided on the outside of the rotating shaft 20. Two fixing screws 22 are threadedly connected inside the installation cylinder 21 and the rotating shaft 20. The two fixing screws 22 are manually screwed into the installation cylinder 21 and the inside of the rotating shaft 20 from one side to install and fix the installation cylinder 21 on the outside of the rotating shaft 20. Then, the fixing screws 22 are screwed to the outside of the fixing screws 22 by means of a nut on the other side. The nut is adjusted to fit against the outer wall of the installation cylinder 21 to improve the stability of the screw insertion of the fixing screws 22. This method is a known technology, and those skilled in the art can and should understand its specific function and structure, so it will not be described in detail here.

[0040] A grinding rotating block 23 is fixedly connected to the bottom of the mounting cylinder 21. Four disassembly blocks 24 are located inside the grinding rotating block 23. Several mounting screws 25 are threadedly connected to the four disassembly blocks 24 and the interior of the grinding rotating block 23. The mounting screws 25 are manually inserted through the disassembly blocks 24 and into the interior of the grinding rotating block 23, facilitating the installation and removal of the disassembly blocks 24 from the outside of the grinding rotating block 23, thereby allowing the installation of the grinding brush 26. It should be noted that the four disassembly blocks 24 can be installed and removed individually. Therefore, personnel can replace the individual polishing brush 26 according to the actual situation, which solves the problem that it is inconvenient to replace the polishing brush when the automatic polishing device is working for a long time. This is conducive to improving the practical performance of the automatic polishing device. The polishing brush 26 is fixedly connected inside the disassembly block 24. The polishing brush 26 is an iron brush. The oxide layer on the outside of the battery terminal is removed by rotating and wiping the battery terminal with the polishing brush 26. The polishing brush 26 is a known technology. Those skilled in the art can and should understand its specific function and structure, so it will not be described in detail here.

[0041] A rotating motor 27 is fixedly connected to the top of the support platform 14. The output end of the rotating motor 27 is fixedly connected to the top of the rotating shaft 20. The output end of the rotating motor 27 drives the rotating shaft 20 to rotate inside the support platform 14 and the positioning cylinder 19. This causes the rotating shaft 20 to drive the mounting cylinder 21 and the grinding rotating block 23 to rotate. In turn, the grinding rotating block 23 drives the disassembly block 24 and the grinding brush 26 to rotate and grind the battery terminals. There is no need for manual hand-held tools to grind the terminals. At the same time, in conjunction with the conveying mechanism 2, production efficiency can be improved and labor costs reduced through automation.

[0042] Two adjusting plates 15 are fixedly connected to the bottom of the support platform 14, and positioning plates 16 are fixedly connected to both sides of the lifting frame 7. Adjusting screws 17 are rotatably connected inside the positioning plates 16.

[0043] The external of the adjusting screw 17 is threadedly connected to the internal of the two adjusting plates 15. One end of the adjusting screw 17 is fixedly connected to a rotating handle 18. When manually setting the automatic grinding device, the adjusting screw 17 is rotated inside the positioning plate 16 by rotating the rotating handle 18. At this time, the two adjusting plates 15 will move and adjust with the rotation of the adjusting screw 17, thereby driving the support 14 and the adjusting block 13 to move and adjust along the two sliding rods 12, so as to adjust the position of the grinding rotating block 23. After the adjustment and setting are completed, the automatic grinding device can start working.

[0044] Two mounting plates 8 are fixedly connected to the top of the grinding device frame 1. A lifting screw 9 is rotatably connected inside the mounting plate 8. The outside of the lifting screw 9 is threadedly connected to the inside of the upper slider 5. A motor 10 is fixedly connected to the top of the mounting plate 8. The output end of the motor 10 is fixedly connected to the top of the lifting screw 9. The output end of the motor 10 drives the lifting screw 9 to rotate, causing the upper slider 5 to rise and fall along the lifting screw 9. This, in turn, drives the lifting frame 7 and related components, including the grinding rotating block 23, to rise and fall. When grinding the battery terminals, the lifting frame 7 drives the grinding rotating block 23 and the grinding brush 26 to fall and cooperate with the grinding brush 26 to grind the battery terminals. After the grinding is completed, the frame 7 rises, allowing the battery to enter the next grinding brush 26, and then the other terminal of the battery is ground.

[0045] The conveying mechanism 2 includes a conveying equipment body 28. The bottom of the conveying equipment body 28 is fixedly connected to one side of the grinding device frame 1. Two positioning frames 29 are provided on the top of the conveying equipment body 28. The conveying equipment body 28 and the two positioning frames 29 are connected to other external equipment. Only a part of them is set at the automatic grinding device. Therefore, this utility model only shows and describes this part. In addition, the conveying equipment body 28 is also a known technology. Those skilled in the art can and should understand its specific functions and structure. Therefore, it will not be described in detail here. The battery is conveyed through the conveying equipment body 28.

[0046] Two fixing cylinders 30 are fixedly connected to the top of one of the positioning frames 29. A fixing plate 31 is fixedly connected to the output end of the fixing cylinder 30. When the battery stops on the main body 28 of the conveying equipment, the output end of the fixing cylinder 30 pushes the fixing plate 31 to move, so that the fixing plate 31 cooperates with the positioning frame 29 to position and fix the battery. The fixing cylinder 30 here is also used in conjunction with a telescopic rod and a telescopic shell. When the output end of the fixing cylinder 30 pushes the fixing plate 301 to move, it will drive the telescopic rod to move inside the telescopic shell. This structure is simple and its specific function and structure are clear to those skilled in the art. This utility model has not made any improvements, so it will not be described in detail here.

[0047] Two L-plates 32 and four mounting blocks 34 are fixedly connected to one side of another positioning frame 29. A photoelectric sensor 33 is fixedly connected inside the L-plate 32. The photoelectric sensor 33 is a diffuse reflection type photoelectric sensor. Its technology is currently very mature and well-known. Those skilled in the art can and should understand its specific function and structure. It uses a light emitter to emit a light beam. When an object enters the sensing range, the light beam is diffusely reflected in all directions after hitting the object's surface. Part of the reflected light returns and is received by the light receiver. The receiver converts the light signal into an electrical signal. After circuit processing, it determines whether an object exists and then triggers an output signal to detect the object. Therefore, the photoelectric sensor 33 is used to detect the battery on the main body 28 of the conveying equipment. When the battery is detected, the positioning cylinder 37 will work to position and intercept the battery. At the same time, the main body 28 of the conveying equipment will temporarily stop working. A guide screw 35 is sleeved inside the mounting block 34. The guide screw 35 is fixed inside the mounting block 34 by a nut.

[0048] A movable block 36 is sleeved on the outside of the guide screw 35. The movable block 36 is fixed to the outside of the guide screw 35 by a nut. During installation, the guide screw 35 is manually inserted into the inside of the mounting block 34 and fixed to the inside of the mounting block 34 by a nut. The positions of the movable block 36 and the positioning cylinder 37 are manually adjusted and fixed by a nut after being set to the appropriate position. The top of the movable block 36 is fixedly connected to the positioning cylinder 37. The piston rod of the positioning cylinder 37 extends to position the battery on the main body 28 of the conveying equipment. After the battery terminal grinding is completed, the piston rod of the positioning cylinder 37 retracts and the main body 28 of the conveying equipment is started to continue conveying the battery.

[0049] Example 2: Figure 9 As shown, Embodiment 2 is basically the same as Embodiment 1. Embodiment 2 is an optimization of Embodiment 1. The similarities will not be repeated. The difference is that Embodiment 2 can use only one automatic grinding mechanism, and the position distance of the two sets of components on the positioning frame 29 (fixed cylinder 30, fixed plate 31, L plate 32, photoelectric sensor 33, moving block 36, positioning cylinder 37) can be adjusted. At the same time, only two mounting blocks 34 and one guide screw 35 are needed.

[0050] The single automatic grinding mechanism frequently rises and falls in conjunction with the conveying mechanism. It can first grind the front terminal of the battery closest to the grinding side, and then continue to convey it. It will then be detected by the second photoelectric sensor 33 and positioned by the positioning cylinder 37. Similarly, after the battery is positioned and fixed, the other terminal is ground. In this way, the two terminals of the battery can be ground one after the other by a single automatic grinding mechanism, without the need to use two automatic grinding mechanisms.

[0051] The automatic pole grinding device works on the following principle:

[0052] First, two fixing screws 22 are manually inserted into the mounting cylinder 21 and the rotating shaft 20 from one side to fix the mounting cylinder 21 to the outside of the rotating shaft 20. Then, the mounting screw 25 is inserted into the disassembly block 24 and spiraled into the grinding rotating block 23 to install the grinding brush 26.

[0053] Secondly, when manually setting up the automatic grinding device, the adjusting screw 17 is rotated inside the positioning plate 16 by rotating the rotating handle 18. At this time, the two adjusting plates 15 will move and adjust with the rotation of the adjusting screw 17, thereby driving the support 14 and the adjusting block 13 to move and adjust along the two sliding rods 12, so as to adjust the position of the grinding rotating block 23. After the adjustment and setting are completed, the automatic grinding device can start working.

[0054] Subsequently, the output end of the rotating motor 27 drives the rotating shaft 20 to rotate inside the support 14 and the positioning cylinder 19, causing the rotating shaft 20 to drive the mounting cylinder 21 and the grinding rotating block 23 to rotate. This causes the grinding rotating block 23 to drive the disassembly block 24 and the grinding brush 26 to rotate and grind the battery terminals. At the same time, it works in conjunction with the conveying mechanism 2 to transport the battery through the conveying equipment body 28. The photoelectric sensor 33 detects the battery on the conveying equipment body 28. When the battery is detected, the positioning cylinder 37 will work to position and intercept the battery. At the same time, the conveying equipment body 28 will temporarily stop working. When the battery stops on the conveying equipment body 28, the output end of the fixing cylinder 30 pushes the fixing plate 31 to move, so that the fixing plate 31 works with the positioning frame 29 to position and fix the battery.

[0055] Finally, the output of motor 10 drives the lifting screw 9 to rotate, causing the upper slider 5 to rise and fall along the lifting screw 9. This, in turn, drives the lifting frame 7 and related components, including the grinding rotating block 23, to rise and fall. When grinding the battery terminals, the lifting frame 7 drives the grinding rotating block 23 and the grinding brush 26 to fall and rotate in coordination with the grinding brush 26 to grind the battery terminals. After the grinding is completed, the lifting frame rises, the piston rod of the positioning cylinder 37 retracts, and the main body of the conveying equipment 28 is started to continue to transport the battery, so that the battery enters the next grinding brush 26, and then the other terminal of the battery is ground. The specific working principle is the same as the first process.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
