Description

Technical Field

[0001] This invention relates to the field of lithium battery processing technology, specifically to a lithium battery processing and assembly apparatus. Background Technology

[0002] Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Due to their characteristics, lithium-ion batteries are widely used, including in the automotive industry, electric bicycles, and other fields where they are indispensable.

[0003] Chinese patent CN216648385U discloses a lithium battery assembly device, including a workbench and a first cylinder. A detection chamber, a first adjusting rod, and a second adjusting rod are fixedly installed on the top of the workbench. The first cylinder is fixedly installed on the top of the detection chamber, and a pressure plate is fixedly installed at one end of the output shaft of the first cylinder. The advantage of this patent is that by placing the assembled lithium batteries on top of a conveyor belt, the conveyor belt moves. When the lithium batteries pass the first set of infrared sensors, if their heights are inconsistent, the laser light illuminating the sensing plate will be blocked. Then, the lithium battery pack moves below the first cylinder, and the first cylinder lowers the pressure plate, pressing down on the lithium batteries. After secondary detection by the second set of infrared sensors, this device can detect and repair poorly assembled lithium batteries, greatly improving the quality of the lithium battery pack.

[0004] However, the current assembly device has the following problems: when the assembly device descends through the pressure plate and performs the pressing operation on the lithium battery, the conveyor belt is not convenient to provide a good support environment for the lithium battery, which leads to uneven distribution of the pressure applied by the pressure plate on the lithium battery, thus affecting the assembly operation of the lithium battery. Therefore, we propose a lithium battery processing and assembly device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a lithium battery processing and assembly apparatus, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lithium battery processing and assembly apparatus, comprising a main body, an internal conveyor belt assembly, infrared sensors on both sides of the main body, a hydraulic cylinder fixed to the top of the main body via a U-shaped frame, a pressure plate fixed to the bottom of the telescopic end of the hydraulic cylinder, a support device below the pressure plate, the support device comprising two crossbeams fixed to the inner wall of the main body, a bonding plate fixed to the top of the two crossbeams, the top surface of the bonding plate contacting the top of the inner wall of the conveyor belt assembly, strip-shaped protrusions on both sides of the top of the bonding plate contacting the outer wall of the conveyor belt assembly, the bonding plate providing support to the top of the inner wall of the conveyor belt assembly, thereby providing a good support environment for the downward assembly of lithium batteries.

[0007] According to the above technical solution, the support device further includes two L-shaped rods and two U-shaped sliding rods. The two U-shaped sliding rods are slidably installed on both sides of the bottom of the bonding plate. A clamping plate is fixed on the side of the top of the two U-shaped sliding rods that are close to each other. The bottom surface of the clamping plate is in contact with the top surface of the conveyor belt of the conveyor belt assembly. The two L-shaped rods are fixed on both sides of the telescopic end of the hydraulic cylinder. A slider is slidably installed on the bottom of the two L-shaped rods, and a spring is provided between the slider and the L-shaped rod. A hinge rod is hinged to the bottom of the slider. The end of the hinge rod away from the slider is hinged to the top of the clamping plate. At the same time, each time the telescopic end of the hydraulic cylinder moves downward, the telescopic end of the hydraulic cylinder will drive the L-shaped rod and the slider to move downward. The slider will first push the hinge rod to move the clamping plate towards the center of the pressure plate, so that the two clamping plates push the lithium battery on the conveyor belt of the conveyor belt assembly to the position directly below the pressure plate.

[0008] According to the above technical solution, elastic telescopic plates are fixed on the top sides of the two clamping plates that are close to each other. At the same time, when the two clamping plates push the lithium battery on the conveyor belt of the conveyor belt group to move, the two clamping plates will cause the elastic telescopic plates to contact the outer wall of the lithium battery.

[0009] According to the above technical solution, a spacer device is provided on one side of the U-shaped frame. The spacer device includes an elastic telescopic column and two elastic telescopic rods. The two elastic telescopic rods are slidably installed on the top sides of the main body of the device. A connecting rod is fixed between the top of the telescopic ends of the two elastic telescopic rods. An L-shaped push plate is fixed on the side of the connecting rod near the U-shaped frame. A second hinge rod is hinged to the side of the telescopic ends of the two elastic telescopic rods that are away from each other. The end of the second hinge rod away from the elastic telescopic rod is hinged to the outer wall of the main body of the device. The fixed end of the elastic telescopic column is fixed to the outer wall of the hydraulic cylinder. The telescopic end of the elastic telescopic column is fixed to the middle of the connecting rod. Each time the extension end of the hydraulic cylinder moves downward, the extension end of the hydraulic cylinder drives the extension end of the elastic telescopic rod to move downward through the elastic telescopic column and connecting rod. Since the movement trajectory of the elastic telescopic rod is restricted by the second hinge rod, during the downward movement of the extension end of the elastic telescopic rod, the entire elastic telescopic rod will also move away from the U-shaped frame along the top of the main body of the device. During this process, the L-shaped push plate will move downward with the extension end of the elastic telescopic rod, and the L-shaped push plate will move away from the U-shaped frame. When the L-shaped push plate moves downward, it will pass over the top surface of the lithium battery. When the L-shaped push plate moves away from the U-shaped frame, it will push the lithium battery that is not under the pressure plate away from the pressure plate.

[0010] According to the above technical solution, the spacer also includes a square groove block, which is fixed to the top of the fixed end of the elastic telescopic column. A square rod is horizontally inserted through the outside of the square groove block and slidably installed. A Z-shaped baffle is fixed on the side of the square rod away from the U-shaped frame. A spring is provided between the Z-shaped baffle and the square groove block. The horizontal support plate of the Z-shaped baffle is at the same level as the bottom of the connecting rod. At the same time, when the extension end of the hydraulic cylinder drives the elastic telescopic column to move downward, the elastic telescopic column will drive the Z-shaped baffle to move downward through the square groove block and the square rod. When the L-shaped push plate pushes the lithium battery that is not under the pressure plate, the lithium battery contacts the Z-shaped baffle, so that the Z-shaped baffle supports the outer wall of the lithium battery.

[0011] According to the above technical solution, an anti-foreign object device is provided on the inner side of the conveyor belt of the conveyor belt assembly. The anti-foreign object device includes a notch box, which is fixed to the inner wall of the main body of the device. A notch is opened on the side of the notch box away from the U-shaped frame. A scraper is fixed on the inner wall of the notch box. The scraper contacts the top of the inner wall of the conveyor belt of the conveyor belt assembly. When the conveyor belt of the conveyor belt assembly is in operation, the scraper will scrape the foreign objects and impurities adhering to the top of the inner wall of the conveyor belt of the conveyor belt assembly into the notch box.

[0012] According to the above technical solution, a connecting plate is fixedly installed at the bottom of the notch box by a spring. An L-shaped limiting rod is fixed at each of the four corners of the connecting plate, and the L-shaped limiting rod is slidably installed on the outside of the notch box. Annular grooves are opened on both sides of the conveyor belt of the conveyor belt assembly. The ends of the four L-shaped limiting rods away from the connecting plate are slidably installed inside the annular grooves on both sides of the conveyor belt of the conveyor belt assembly. At the same time, under the elastic force of the spring corresponding to the connecting plate, the connecting plate pulls the conveyor belt of the conveyor belt assembly to fit tightly against the scraper through the L-shaped limiting rods.

[0013] This invention provides a lithium battery processing and assembly apparatus. It has the following beneficial effects:

[0014] (1) The present invention, through the setting of the support device, enables the bonding plate to support the top of the inner wall of the conveyor belt of the conveyor belt assembly, thereby providing a good support environment for the pressing and assembly of lithium batteries, thus avoiding the problem of uneven distribution of pressure applied to the lithium battery by the pressure plate, which affects the assembly of lithium batteries. Through the contact between the strip-shaped protrusion of the bonding plate and the outer wall of the conveyor belt of the conveyor belt assembly, the bonding plate can effectively control the position of the conveyor belt of the conveyor belt assembly, ensuring that the conveyor belt of the conveyor belt assembly does not shift or slide during operation; at the same time, the hydraulic cylinder, L-shaped rod, slider, hinge rod, clamping plate, and pressure plate work together to drive the two clamping plates to push the lithium battery on the conveyor belt of the conveyor belt assembly to the position directly below the pressure plate, thereby ensuring the pressure plate When pressing down, it can accurately act on the center of the lithium battery, avoiding uneven pressing caused by misalignment or offset of the lithium battery, thereby improving the accuracy of lithium battery assembly. At the same time, the two clamping plates drive the elastic telescopic plate to contact the outer wall of the lithium battery. When the pressure plate moves down, it will first contact the top of the telescopic end of the elastic telescopic plate. As the pressure plate continues to move down, the pressure plate pushes the telescopic end of the elastic telescopic plate to extend and retract until the pressure plate contacts the top of the lithium battery and presses the lithium battery down for assembly. The elastic telescopic plate plays a buffering role when the pressure plate continues to press down, which helps to reduce the impact force generated when the pressure plate directly contacts the lithium battery. It can effectively avoid the lithium battery being subjected to sudden strong impacts and reduce the risk of battery damage or deformation.

[0015] (2) By setting up an interval device, the present invention enables the hydraulic cylinder, elastic telescopic column, connecting rod, elastic telescopic rod and hinge rod to work together to drive the L-shaped push plate to push the lithium battery that is not under the pressure plate away from the pressure plate, thereby avoiding the problem that the lithium battery is at the edge of the pressure plate and will interfere with or affect the operation of the pressure plate. This can improve the accuracy of the pressure plate when pressing down and assembling the lithium battery and reduce the problems caused by unnecessary contact or misoperation. At the same time, the hydraulic cylinder, elastic telescopic column, square groove block, square rod and Z-shaped baffle work together to drive the Z-shaped baffle to form support for the outer wall of the lithium battery, thereby avoiding the problem that the lithium battery will tip over after the L-shaped push plate pushes the lithium battery too much, which will affect the subsequent pressing down and assembly operation of the lithium battery.

[0016] (3) By setting up the foreign object prevention device, the scraper will scrape the foreign objects and impurities adhering to the top of the inner wall of the conveyor belt into the notch box, thereby avoiding the problem of foreign objects and impurities entering between the bonding plate and the conveyor belt of the conveyor belt, causing abnormal local bulging of the conveyor belt of the conveyor belt, thus ensuring that the conveyor belt of the conveyor belt can stably transport lithium batteries; at the same time, under the action of the three spring forces corresponding to the connecting plate, the connecting plate pulls the conveyor belt of the conveyor belt and the scraper to fit tightly through the L-shaped limiting rod, thereby facilitating the scraper to scrape the foreign objects and impurities embedded in the conveyor belt of the conveyor belt into the notch box, thereby improving the effect of the scraper in removing foreign objects and impurities adhering to the top of the inner wall of the conveyor belt of the conveyor belt.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Please see Figure 1 - Figure 8 One embodiment of the present invention is as follows: a lithium battery processing and assembly apparatus includes a main body 1, a conveyor belt assembly 3 inside the main body 1, infrared sensors 2 on both sides of the main body 1, a hydraulic cylinder 5 fixed to the top of the main body 1 by a U-shaped frame 4, a pressure plate 6 fixed to the bottom of the telescopic end of the hydraulic cylinder 5, a support device 7 below the pressure plate 6, the support device 7 including two crossbeams 71, both crossbeams 71 fixed to the inner wall of the main body 1, and a bonding plate 72 fixed to the top of the two crossbeams 71, the top surface of the bonding plate 72 contacting the top of the inner wall of the conveyor belt of the conveyor belt assembly 3. Through the above structural arrangement, the... The bonding plate 72 provides support to the top of the inner wall of the conveyor belt of the conveyor belt assembly 3, thus providing a good support environment for the pressing and assembly of lithium batteries. This avoids the problem of uneven pressure distribution on the lithium batteries by the pressure plate 6, which would affect the assembly of lithium batteries. The bonding plate 72 has strip-shaped protrusions on both sides of its top, and these protrusions contact the outer wall of the conveyor belt of the conveyor belt assembly 3. By contacting the outer wall of the conveyor belt of the conveyor belt assembly 3 with the strip-shaped protrusions of the bonding plate 72, the bonding plate 72 can effectively control the position of the conveyor belt of the conveyor belt assembly 3, ensuring that the conveyor belt of the conveyor belt assembly 3 does not shift or slide during operation.

[0028] The support device 7 also includes two L-shaped rods 75 and two U-shaped slide rods 73. The two U-shaped slide rods 73 are slidably installed on both sides of the bottom of the bonding plate 72. The top of the two U-shaped slide rods 73 are fixed with clamping plates 77 on the side that is close to each other. The bottom surface of the clamping plates 77 is in contact with the top surface of the conveyor belt of the conveyor belt group 3. The two L-shaped rods 75 are fixed on both sides of the telescopic end of the hydraulic cylinder 5. The bottom of the two L-shaped rods 75 is slidably installed with sliders 76, and a spring is provided between the sliders 76 and the L-shaped rods 75. The bottom of the sliders 76 is hinged with a hinge rod 74. The end of the hinge rod 74 away from the slider 76 is hinged to the top of the clamping plate 77. With the above structure, the two clamping plates 77 push the lithium battery on the conveyor belt of the conveyor belt group 3 to the position directly below the pressure plate 6, thereby ensuring that the pressure plate 6 can accurately act on the center of the lithium battery when pressing down, avoiding uneven pressing caused by misalignment or offset of the lithium battery, and thus improving the accuracy of lithium battery assembly.

[0029] On the top sides of the two clamping plates 77 that are close to each other, there are elastic telescopic plates 78. Through the above structure, the elastic telescopic plates 78 play a buffering role when the pressure plate 6 continues to press down. This helps to reduce the impact force generated when the pressure plate 6 comes into direct contact with the lithium battery, and can effectively prevent the lithium battery from being subjected to sudden strong impact, reducing the risk of battery damage or deformation.

[0030] A spacer device 8 is provided on one side of the U-shaped frame 4. The spacer device 8 includes an elastic telescopic column 85 and two elastic telescopic rods 81. The two elastic telescopic rods 81 are slidably installed on the top two sides of the main body 1 of the device. A connecting rod 83 is fixed between the top of the telescopic ends of the two elastic telescopic rods 81. An L-shaped push plate 84 is fixed on the side of the connecting rod 83 near the U-shaped frame 4. A hinge rod 82 is hinged to the side of the telescopic ends of the two elastic telescopic rods 81 that are far away from each other. The end of the hinge rod 82 that is far away from the elastic telescopic rod 81 is hinged to the outer wall of the main body 1 of the device. The fixed end of the elastic telescopic column 85 is fixed to the outer wall of the hydraulic cylinder 5. The telescopic end of the elastic telescopic column 85 is fixed to the middle of the connecting rod 83. With the above structure, the L-shaped push plate 84 pushes the lithium battery that is not under the pressure plate 6 away from the pressure plate 6, thereby avoiding the problem that the lithium battery being at the edge of the pressure plate 6 will interfere with or affect the operation of the pressure plate 6. This can improve the accuracy of the pressure plate 6 when pressing down and assembling the lithium battery and reduce problems caused by unnecessary contact or misoperation.

[0031] The spacer device 8 also includes a square groove block 86, which is fixed to the top of the fixed end of the elastic telescopic column 85. A square rod 87 is horizontally inserted through the outside of the square groove block 86 and slidably installed. A Z-shaped baffle 88 is fixed on the side of the square rod 87 away from the U-shaped frame 4. A spring is provided between the Z-shaped baffle 88 and the square groove block 86. The horizontal support plate of the Z-shaped baffle 88 is at the same level as the bottom of the connecting rod 83. Through the above structure, the Z-shaped baffle 88 provides support for the outer wall of the lithium battery, thereby avoiding the problem that the lithium battery will tip over after the L-shaped pusher plate 84 pushes the lithium battery excessively, which would affect the subsequent lithium battery pressing and assembly operation.

[0032] In use, the assembled lithium battery is placed on top of the conveyor belt of conveyor belt group 3, and then the conveyor belt group 3 is started. The conveyor belt group 3 will transport the lithium battery. When the lithium battery passes the infrared sensor 2, if the lithium battery height is inconsistent, it will block the laser light from the infrared sensor 2 from shining on the corresponding sensing plate of the infrared sensor 2. Then the lithium battery group moves to the bottom of the hydraulic cylinder 5. The telescopic end of the hydraulic cylinder 5 pushes the pressure plate 6 down and performs the pressing operation on the lithium battery. During the pressing assembly operation of the lithium battery, the bonding plate 72 will press against the inner wall of the conveyor belt of the conveyor belt group 3. The pressure plate 6 forms a support, providing a good support environment for the pressing and assembly of lithium batteries. This avoids uneven pressure distribution on the lithium batteries, which could affect the assembly process. The strip-shaped protrusions of the bonding plate 72 contact the outer wall of the conveyor belt of the conveyor belt assembly 3, allowing the bonding plate 72 to effectively control the position of the conveyor belt of the conveyor belt assembly 3, ensuring that the conveyor belt of the conveyor belt assembly 3 does not shift or slide during operation. Simultaneously, each time the extension end of the hydraulic cylinder 5 moves downward, the extension end of the hydraulic cylinder 5 drives the L-shaped rod 75 and the slider. When slider 76 moves downwards, it first pushes hinge rod 74, causing clamping plate 77 to move towards the center of pressure plate 6. This allows the two clamping plates 77 to push the lithium battery on the conveyor belt of conveyor belt group 3 to a position directly below pressure plate 6. This ensures that pressure plate 6 accurately acts on the center of the lithium battery when pressing down, avoiding uneven pressing caused by misalignment or offset of the lithium battery, thus improving the accuracy of lithium battery assembly. At the same time, when the two clamping plates 77 push the lithium battery on the conveyor belt of conveyor belt group 3, the two clamping plates 77 will... The flexible telescopic plate 78 contacts the outer wall of the lithium battery. When the pressure plate 6 moves downward, it first contacts the top of the telescopic end of the flexible telescopic plate 78. As the pressure plate 6 continues to move downward, it pushes the telescopic end of the flexible telescopic plate 78 to extend and retract until the pressure plate 6 contacts the top of the lithium battery and presses it down to assemble the lithium battery. The flexible telescopic plate 78 acts as a buffer when the pressure plate 6 continues to press down, which helps to reduce the impact force generated when the pressure plate 6 directly contacts the lithium battery. This can effectively prevent the lithium battery from being subjected to sudden strong impacts and reduce the risk of battery damage or deformation.

[0033] Each time the extension end of the hydraulic cylinder 5 moves downward, the extension end of the hydraulic cylinder 5 drives the extension end of the elastic extension rod 81 downward through the elastic extension column 85 and the connecting rod 83. Since the movement trajectory of the elastic extension rod 81 is restricted by the hinge rod 82, during the downward movement of the extension end of the elastic extension rod 81, the entire elastic extension rod 81 will also move along the top of the main body 1 away from the U-shaped frame 4. During this process, the L-shaped push plate 84 will move downward with the extension end of the elastic extension rod 81, and the L-shaped push plate 84 will move away from the U-shaped frame 4. When the L-shaped push plate 84 moves downward, it will pass over the top surface of the lithium battery. When the L-shaped push plate 84 moves away from the U-shaped frame 4, it will push the lithium battery that is not below the pressure plate 6 away from the pressure plate 6, thereby avoiding the problem that the lithium battery being at the edge of the pressure plate 6 will interfere with or affect the operation of the pressure plate 6. This can improve the accuracy of the pressure plate 6 when pressing and assembling lithium batteries, and reduce problems caused by unnecessary contact or misoperation. At the same time, when the extension end of the hydraulic cylinder 5 drives the elastic telescopic column 85 to move downward, the elastic telescopic column 85 will drive the Z-shaped baffle 88 to move downward through the square slot block 86 and the square rod 87. When the L-shaped push plate 84 pushes the lithium battery that is not under the pressure plate 6, the lithium battery contacts the Z-shaped baffle 88, so that the Z-shaped baffle 88 supports the outer wall of the lithium battery. This avoids the problem of the lithium battery tipping over after the L-shaped push plate 84 pushes the lithium battery excessively, affecting the subsequent pressing and assembly of lithium batteries. It should also be noted that when there are too many lithium batteries between the Z-shaped baffle 88 and the L-shaped push plate 84, the pushing of the Z-shaped baffle 88 will drive the square rod 87 to move laterally along the inside of the square slot block 86, and the spring 2 between the Z-shaped baffle 88 and the square slot block 86 will be stretched.

[0034] Please see Figure 1 - Figure 8 Based on the above embodiments, in another embodiment of the present invention, an anti-foreign object device 9 is provided on the inner side of the conveyor belt of the conveyor belt group 3.

[0035] The foreign object prevention device 9 includes a notch box 91, which is fixed to the inner wall of the device body 1. The notch box 91 has a notch on the side away from the U-shaped frame 4. A scraper 92 is fixed to the inner wall of the notch box 91. The scraper 92 contacts the top of the inner wall of the conveyor belt of the conveyor belt assembly 3. With the above structure, the scraper 92 scrapes the foreign objects adhering to the top of the inner wall of the conveyor belt of the conveyor belt assembly 3 into the notch box 91, thereby preventing foreign objects from entering between the bonding plate 72 and the conveyor belt of the conveyor belt assembly 3, which would cause the conveyor belt of the conveyor belt assembly 3 to bulge abnormally in some areas. This ensures that the conveyor belt of the conveyor belt assembly 3 can stably transport lithium batteries.

[0036] A connecting plate 94 is fixedly installed at the bottom of the notch box 91 by a spring. L-shaped limiting rods 93 are fixed at the four corners of the connecting plate 94 and are slidably installed on the outside of the notch box 91. Annular grooves are opened on both sides of the conveyor belt of the conveyor belt assembly 3. The ends of the four L-shaped limiting rods 93 away from the connecting plate 94 are slidably installed inside the annular grooves on both sides of the conveyor belt of the conveyor belt assembly 3. Through the above structure, the L-shaped limiting rods 93 pull the conveyor belt of the conveyor belt assembly 3 to fit tightly against the scraper 92, thereby facilitating the scraper 92 to scrape foreign objects embedded in the conveyor belt of the conveyor belt assembly 3 into the notch box 91, thus improving the effect of the scraper 92 in removing foreign objects adhering to the top of the inner wall of the conveyor belt of the conveyor belt assembly 3.

[0037] During use, when the conveyor belt of the conveyor belt assembly 3 is in operation, the scraper 92 scrapes the foreign matter and impurities adhering to the top of the inner wall of the conveyor belt of the conveyor belt assembly 3 into the notch box 91. This prevents foreign matter and impurities from entering between the bonding plate 72 and the conveyor belt of the conveyor belt assembly 3, which could cause abnormal local bulging of the conveyor belt of the conveyor belt assembly 3. This ensures that the conveyor belt of the conveyor belt assembly 3 can stably transport lithium batteries. At the same time, under the action of the three spring forces corresponding to the connecting plate 94, the connecting plate 94 pulls the conveyor belt of the conveyor belt assembly 3 and the scraper 92 to fit tightly together through the L-shaped limiting rod 93. This facilitates the scraper 92 to scrape the foreign matter and impurities embedded in the conveyor belt of the conveyor belt assembly 3 into the notch box 91, thereby improving the effect of the scraper 92 in removing foreign matter and impurities adhering to the top of the inner wall of the conveyor belt of the conveyor belt assembly 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
