Description

Technical Field

[0001] This utility model relates to the field of battery sealing equipment technology, and in particular to a sealing device for lithium-ion battery preparation. Background Technology

[0002] A sealing device for lithium-ion battery manufacturing is a piece of equipment used to seal the opening of the battery casing during the lithium-ion battery production process. After the lithium-ion battery is assembled, a sealed environment is required to prevent the electrolyte inside the battery from leaking out, and at the same time to prevent external air, moisture and other substances from entering the battery and affecting its performance and lifespan.

[0003] In the current lithium battery processing, sealing is required. Existing sealing equipment typically fixes the battery in place before sealing to prevent movement. However, this method is time-consuming and reduces the processing efficiency of lithium batteries. Furthermore, placing lithium batteries requires constant manual handling, as sealing and retrieval cannot be automated. This process is physically demanding for employees and also reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that prevents batteries from moving. Usually, the batteries are fixed first and then sealed. However, this method is time-consuming, which reduces the processing efficiency of lithium batteries. When placing lithium batteries, manual handling is required to continuously pick them up and put them in. Sealing and collecting cannot be automated. In the production process, this consumes a lot of the employees' physical strength and also reduces production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealing device for lithium-ion battery manufacturing, comprising: a base, a support seat fixedly installed on the top of the base, a motor fixedly installed on one side of the support seat, a battery conveyor belt fixedly installed on the output shaft of the motor, guardrails fixedly installed on both sides of the battery conveyor belt, two support blocks fixedly connected to the outer surface of the guardrails, a cylinder fixedly installed on the top of the base, a fixing plate fixedly connected to the output shaft of the cylinder, a U-groove plate fixedly connected to one side of the fixing plate, a fixing block fixedly connected to the top of the base, and a buffer limiting rod fixedly connected inside the fixing block.

[0006] The technical effect of adopting the above-mentioned further solution is as follows: the output shaft of the motor drives the battery conveyor belt to start moving, and the battery conveying mechanism is connected to the battery conveyor belt, so that the battery can be conveyed upright from the outer surface of the battery conveyor belt. When it reaches the inside of the U-shaped plate, the battery is blocked by the fixed block. The output shaft of cylinder one pushes the fixed plate, and the movement of the fixed plate drives the U-shaped plate to move synchronously into the inside of the sealing worktable. The movement of the U-shaped plate drives the battery to reach the middle of the two sliding limit blocks.

[0007] In a preferred embodiment, a support plate is fixedly installed on the top of the base, a second cylinder is fixedly installed inside the support plate near the top, a movable plate is fixedly connected to the output shaft of the second cylinder, a sealing machine is fixedly connected to the bottom of the movable plate, two buffer columns are fixedly installed at the bottom of the movable plate, springs are sleeved on the outer surfaces of the two buffer columns, and two guide columns are fixedly installed at the bottom of the movable plate.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: the support plate is used to support cylinder two, the output shaft of cylinder two pushes the moving plate, the moving plate moves downward to drive the sealing machine to seal the battery, and the moving plate moves downward to drive the buffer column to contact the extrusion block. Spring two is used to buffer both when the buffer column contacts the extrusion block downward.

[0009] In a preferred embodiment, two extrusion blocks are movably connected to the top of the sealing workbench, and two telescopic columns are fixedly installed inside the sealing workbench. A movable plate is movably connected to one side of each of the two telescopic columns, a push rod is fixedly connected to one side of each of the two movable plates, a spring is fixedly connected to one side of each of the two movable plates, and a wedge block is fixedly connected to the other side of each of the two push rods.

[0010] The technical effect of adopting the above-mentioned further solution is as follows: after the extrusion block is squeezed, it squeezes the telescopic column downward. After the telescopic column is squeezed, it begins to push the movable plate. The movable plate pushes the wedge block through the push rod. When the extrusion of the extrusion block disappears, the wedge block returns to its original position through the rebound of the spring.

[0011] In a preferred embodiment, the sealing workbench is internally fixedly connected with multiple slide rails, which are divided into two groups on average. Each group of slide rails is movably connected to a sliding limit block at its top.

[0012] The technical effect of adopting the above-mentioned further solution is that after the sliding limit block is pushed by the wedge block, the two sliding limit blocks slide on the outer surface of the slide rail and move in opposite directions to fix the battery.

[0013] In a preferred embodiment, a T-shaped plate is movably connected inside the sealing workbench, a cylinder is fixedly connected to one side of the T-shaped plate, a collection box is fixedly connected to the bottom of the base, and multiple support legs are fixedly connected to the bottom of the base.

[0014] The technical effect of adopting the above-mentioned further solution is that the cylinder pushes the T-shaped plate to move, and the T-shaped plate drives the battery to move synchronously with the T-shaped plate. When it reaches the notch of the base, the battery falls into the inside of the collection box.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, when in use, the operator starts the motor and cylinder one. The output shaft of the motor drives the battery conveyor belt to start moving. The battery conveying mechanism is connected to the battery conveyor belt, allowing the battery to be conveyed upright from the outer surface of the battery conveyor belt. When the battery reaches the inside of the U-shaped plate, it is blocked by the fixing block. The output shaft of cylinder one pushes the fixing plate, and the movement of the fixing plate drives the U-shaped plate to move synchronously into the sealing workbench. The movement of the U-shaped plate drives the battery to the middle of the two sliding limit blocks, thus solving the problem of needing to be constantly picked up and placed manually.

[0017] This invention involves starting cylinder two, whose output shaft drives the sealing machine, causing the sealing machine to move spring two downwards. Spring two then moves the buffer column downwards to contact the extrusion block and compress it. The extrusion block, after being compressed, compresses the telescopic column downwards. The telescopic column, after being compressed, begins to push the movable plate. The movable plate, through a push rod, compresses the wedge block. The wedge block moves and pushes the sliding limit block to slide on the outer surface of the slide rail. After the two sliding limit blocks move relative to each other, they fix the battery. The sealing machine then seals the battery. After sealing, cylinder three is started, which pushes the T-shaped plate to move. The T-shaped plate moves the battery synchronously with it. When the battery reaches the notch in the base, it falls into the collection box. This solves the problem of needing to constantly fix the battery before sealing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a sealing device for lithium-ion battery manufacturing, comprising: a base 1, a support seat 101 fixedly installed on the top of the base 1, a motor 102 fixedly installed on one side of the support seat 101, a battery conveyor belt 103 fixedly installed on the output shaft of the motor 102, guardrails 104 fixedly installed on both sides of the battery conveyor belt 103, two support blocks 105 fixedly connected to the outer surface of the guardrails 104, a cylinder 106 fixedly installed on the top of the base 1, a fixing plate 107 fixedly connected to the output shaft of the cylinder 106, a U-shaped groove plate 108 fixedly connected to one side of the fixing plate 107, and a U-shaped groove plate 108 fixedly connected to the top of the base 1. A fixed block 109 is fixedly connected, and a buffer limit rod 110 is fixedly connected inside the fixed block 109. The output shaft of the motor 102 drives the battery conveyor belt 103 to start moving. The battery conveying mechanism is connected to the battery conveyor belt 103, so that the battery can be conveyed upright from the outer surface of the battery conveyor belt 103. When the battery reaches the inside of the U-shaped plate 108, it is blocked by the fixed block 109. The output shaft of the cylinder 106 pushes the fixed plate 107. The movement of the fixed plate 107 drives the U-shaped plate 108 to move synchronously into the sealing workbench 2. The movement of the U-shaped plate 108 drives the battery to reach the middle of the two sliding limit blocks 207.

[0026] like Figures 1 to 4 As shown, a support plate 218 is fixedly installed on the top of the base 1. A cylinder 209 is fixedly installed inside the support plate 218 near the top. The output shaft of the cylinder 209 is fixedly connected to a moving plate 217. A sealing machine 210 is fixedly connected to the bottom of the moving plate 217. Two buffer pillars 212 are fixedly installed at the bottom of the moving plate 217. Springs 211 are sleeved on the outer surface of the two buffer pillars 212. Two guide pillars 213 are fixedly installed at the bottom of the moving plate 217. The support plate 218 is used to support the cylinder 209. The output shaft of the cylinder 209 pushes the moving plate 217. The moving plate 217 moves downward, causing the sealing machine 210 to seal the battery. At the same time, the moving plate 217 moves downward, causing the buffer pillars 212 to contact the pressing block 201. Springs 211 are used to buffer the two when the buffer pillars 212 contact the pressing block 201 downward.

[0027] like Figures 1 to 4 As shown, a sealing workbench 2 is fixedly connected to the upper surface of the base 1. Two extrusion blocks 201 are movably connected to the top of the sealing workbench 2. Two telescopic columns 202 are fixedly installed inside the sealing workbench 2. Movable plates 203 are movably connected to one side of each of the two telescopic columns 202. Push rods 204 are fixedly connected to one side of each of the two movable plates 203. Springs 205 are fixedly connected to one side of each of the two movable plates 203. Wedge blocks 206 are fixedly connected to the other side of each of the two push rods 204. When the extrusion blocks 201 are extruded, they extrude downwards to extrude the telescopic columns 202. When the telescopic columns 202 are extruded, they begin to push the movable plates 203. The movable plates 203 push the wedge blocks 206 through the push rods 204. When the extrusion of the extrusion blocks 201 disappears, the wedge blocks 206 return to their original position due to the rebound of the springs 205.

[0028] like Figures 1 to 4 As shown, the sealing workbench 2 has multiple slide rails 208 fixedly connected inside. The slide rails 208 are divided into two groups. Each group of slide rails 208 has a sliding limit block 207 movably connected to its top. After the sliding limit block 207 is pushed by the wedge block 206, the two sliding limit blocks 207 slide on the outer surface of the slide rail 208 and move in opposite directions to fix the battery.

[0029] like Figures 1 to 4 As shown, a T-shaped plate 214 is movably connected inside the sealing workbench 2. A cylinder 215 is fixedly connected to one side of the T-shaped plate 214. A collection box 216 is fixedly connected to the bottom of the base 1. Multiple support legs 111 are fixedly connected to the bottom of the base 1. The cylinder 215 pushes the T-shaped plate 214 to move. The T-shaped plate 214 drives the battery to move synchronously with the T-shaped plate 214. When it reaches the notch of the base 1, the battery falls into the inside of the collection box 216.

[0030] Working Principle: This equipment is a sealing device for lithium-ion battery manufacturing. During use, the operator starts motor 102 and cylinder 106. The output shaft of motor 102 drives the battery conveyor belt 103 to move. The battery conveying mechanism is connected to the battery conveyor belt 103, allowing the batteries to be conveyed upright from the outer surface of the conveyor belt 103. When the batteries reach the inside of the U-shaped plate 108, they are blocked by the fixing block 109. The output shaft of cylinder 106 pushes the fixing plate 107, causing the U-shaped plate 108 to move synchronously into the sealing worktable 2. The movement of the U-shaped plate 108 brings the batteries to the middle of the two sliding limit blocks 207, solving the problem of needing constant manual handling. Then, cylinder 209 is started, and its output shaft pushes the sealing machine 210, causing the sealing machine 210 to move the spring 211 towards the sealing worktable 2. The spring 211 moves downward, causing the buffer column 212 to move downward and contact the compression block 201 to compress it. After being compressed, the compression block 201 compresses the telescopic column 202 downward. After being compressed, the telescopic column 202 begins to push the movable plate 203. The movable plate 203 compresses the wedge block 206 through the push rod 204. The wedge block 206 moves and pushes the sliding limit block 207 to slide on the outer surface of the slide rail 208. After the two sliding limit blocks 207 move relative to each other, they fix the battery. Then the sealing machine 210 performs a sealing operation on the battery. After sealing is completed, the cylinder 215 is started. The cylinder 215 pushes the T-shaped plate 214 to move. The T-shaped plate 214 drives the battery to move synchronously with the T-shaped plate 214. When it reaches the notch of the base 1, the battery falls into the inside of the collection box 216, which solves the problem of needing to continuously fix the battery before sealing.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
