Description

Technical Field

[0001] The present invention relates to the field of material conveying equipment for lithium battery production lines, and in particular to a material collection system for lithium battery production lines. Background Art

[0002] Lithium batteries use lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. They offer advantages such as high energy density and long service life. Under the action of an external power source, lithium ions are released from the positive electrode material, migrate through the electrolyte to the negative electrode, and then embed themselves into the negative electrode material's lattice. Simultaneously, electrons flow from the positive electrode to the negative electrode through an external circuit to maintain charge balance.

[0003] In lithium battery production lines, batteries are stacked on the ground near equipment before being transported. This requires significant manual handling, and batteries may not be transferred from storage to the next piece of equipment in a timely manner, leading to production interruptions. This accelerates equipment wear, reduces equipment life, increases repair and replacement costs, and significantly increases labor consumption. After loading, materials may remain in their initial position, lacking a push mechanism, preventing them from smoothly entering subsequent processing or transport stages. Other production equipment may become idle while waiting for materials, slowing overall production and significantly reducing efficiency, increasing the risk of equipment failure. When batteries are transported on different conveyor belts, material transfer between conveyor lines can become chaotic. Materials may not smoothly transition from one conveyor line to another as required by the production process, leading to interruptions or disruptions in the production process. During transport, materials may need to adjust their position according to the requirements of different process steps, making it difficult to accurately adjust the material's position, affecting the smooth progress of subsequent processes, reducing overall production efficiency, and affecting the performance and quality stability of the batteries.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can solve the problems of production interruption, accelerated equipment wear, reduced equipment service life, increased equipment maintenance and replacement costs, and greatly increased manpower consumption by setting a lifting and loading mechanism. When the first placement plate and the second placement plate enter the bottom of the battery tray, the limit block inside the second placement plate will contact the bottom wall of the battery tray, causing the limit block to rotate to the right in the hole groove on the upper side wall of the second placement plate, so that the limit block retracts into the hole groove of the second placement plate. When the first placement plate and the second placement plate are completely entered into the battery tray, After the battery tray is pulled to the bottom, the limit block will rebound through the spring at the bottom to reset the limit block. When the battery tray is pulled out, the right side wall of the limit block will contact the left side wall of the bottom of the battery tray. At the same time, the left side wall of the limit block will contact and limit the inner wall of the hole groove on the upper side wall of the second placement plate to prevent the limit block from rotating to the left, and support the left side of the battery tray when pulling, so as to pull the battery tray back to the upper side wall of the tray, thereby effectively improving and reducing the time interval of material transmission, making each production link closely coordinated, improving the overall production rhythm, and reducing the physical consumption of workers.

[0016] 2. The provided bracket, electric push rod, first support rod, I-block and push plate can solve the problems that slow down the overall production rhythm, significantly reduce production efficiency and increase the risk of equipment failure. During the rotation of the first support rod, its top drives the I-block to move to the right, and the second support rod connected to the I-block inside the rotation also moves accordingly. Since the right side wall of the second support rod is fixedly connected to the push plate, the bottom of the push plate is in contact with the upper side wall of the bracket and is supported and guided by the bracket, the push plate will slide to the right along the upper surface of the bracket under the push of the second support rod, thereby effectively reducing the waiting time of the equipment, improving the overall production rhythm, and reducing errors and defects in the production process.

[0017] 3. The rotary clamping mechanism can solve the problem of difficulty in accurately adjusting the material posture, affecting the smooth progress of subsequent processes, reducing overall production efficiency, and affecting the performance and quality stability of batteries. When the moving block slides outward, the connecting block also moves outward, causing the clamping blocks fixed to the bottom wall of the connecting block to move away from each other, thereby expanding the distance between the clamping blocks and preparing to clamp the material. Subsequently, the material to be processed is placed in the appropriate position between the clamping blocks. At this time, the telescopic end of the third hydraulic rod begins to contract, driving the third connecting plate to descend. Through the linkage of the pull rod and the second articulated frame, the clamping blocks will move closer to each other, eventually clamping the material tightly and completing the clamping action of the material, thereby effectively reducing the residence time of the material during the conveying process, speeding up the material flow speed on the entire production line, and avoiding poor assembly due to component position deviation or incorrect posture.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] like Figure 1 - Figure 6As shown: A material collection system for a lithium battery production line includes a conveyor belt 1, and a lifting and loading mechanism 2 is provided on the left side wall of the conveyor belt 1; the lifting and loading mechanism 2 includes: two first guide rails 201, a first device box 202, two first motors 203 and two coupling blocks 208, the right side walls of the two first guide rails 201 are fixedly connected to the front and rear sides of the left side wall of the conveyor belt 1, the right side wall of the first device box 202 is fixedly connected to the bottom of the left side wall of the conveyor belt 1, and the bottom walls of the two first motors 203 are fixedly connected to the front and rear sides inside the first device box 202, and the first device box 202 is provided to protect the inside of the first motor 203 from the outside, and the first device box 202 is used to fix the first motor 203 to the bottom of the left side wall of the conveyor belt 1.

[0041] The output ends of the two first motors 203 are fixedly connected to the first rotating shaft 204, and the other ends of the two first rotating shafts 204 are fixedly connected to the tensioning pulleys 205. The interiors of the two first guide rails 201 are slidably connected to the belts 206. The bottoms of the two belts 206 are arranged inside the two tensioning pulleys 205. The left side walls of the two first guide rails 201 are provided with first sliders 207. The left side parts of the two belts 206 are threadedly connected to the interior of the first sliders 207 through the coupling blocks 208. The right side walls of the two first sliders 207 are fixedly connected to pulleys 209. Every four pulleys 209 are slidably connected to the hole slots on the front and rear sides of a first guide rail 201, and the first rotating shaft 204 is driven to rotate through the output end of the first motor 203, thereby The tensioning wheel 205 fixed at the other end of the first rotating shaft 204 rotates synchronously. Since the two first guide rails 201 are both slidably connected to the inside of the belt 206, and the bottom of the belt 206 is set inside the tensioning wheel 205, the rotation of the tensioning wheel 205 drives the belt 206 to circulate in the first guide rail 201. The left part of the belt 206 is threadedly connected to the inside of the first slider 207 through the coupling block 208. Therefore, the movement of the belt 206 will drive the first slider 207 to slide up and down along the left side wall of the first guide rail 201. The pulley 209 fixedly connected to the right side wall of the first slider 207 slides in the hole grooves on the front and rear sides of the first guide rail 201, playing a role of auxiliary support and guidance, ensuring that the first slider 207 moves up and down smoothly.

[0042] like Figure 7 - Figure 9As shown: the left side walls of the two first sliders 207 are fixedly connected to the first connecting plate 210, and the left side wall of the first connecting plate 210 is fixedly connected to the supporting plate 211, which is connected to the two first sliders 207 through the right side wall of the first connecting plate 210. When the first slider 207 drives the first connecting plate 210 to move up and down, the left side wall of the first connecting plate 210 is connected to the supporting plate 211, thereby driving the supporting plate 211 to slide up and down together. The inner walls of the front and rear sides of the support plate 211 are provided with track grooves 212, and the bottom wall hole grooves of the support plate 211 are provided with first hydraulic rods 213. The outer sides of the telescopic ends of the two first hydraulic rods 213 are rotatably connected to the first hinge frames 214. The upper side walls of the two first hinge frames 214 are fixedly connected to the first placement plate 215. The front and rear side walls of the first placement plate 215 are fixedly connected to the second sliders 216. The outer sides of the two second sliders 216 are slidably connected to the inside of the track groove 212. When the support plate 211 drops to the bottom, the support plate 211 is moved through the inner side thereof. The first hinge frame 214 on the telescopic end of the first hydraulic rod 213 is connected to the first placement plate 215, and when the first hydraulic rod 213 is started, it drives the first placement plate 215 to slide to the left and slide to the bottom of the battery tray to pull the battery tray into the support plate 211. When the first placement plate 215 slides, the second sliders 216 on the front and rear side walls slide in the track groove 212 on the inner wall of the support plate 211 to support the first placement plate 215 and improve the stability of the first placement plate 215 when sliding.

[0043] The front and rear sides of the right side of the first placement plate 215 are fixedly connected with a second hydraulic rod 217, and the interior of the first placement plate 215 is slidably connected with a second placement plate 218. The telescopic ends of the two second hydraulic rods 217 are fixedly connected to the right side wall of the second placement plate 218, and the upper side wall of the second placement plate 218 is internally rotatably connected to a limiting block 219. When the length of the first placement plate 215 cannot contact the battery tray on the left, the second hydraulic rod 217 inside the first placement plate 215 will drive the second placement plate 218 to slide, thereby lengthening the length of the first placement plate 215 and pulling the battery tray, etc.

[0044] As shown in the upper part, when the first placement plate 215 and the second placement plate 218 enter the bottom of the battery tray, the limit block 219 inside the second placement plate 218 will contact the bottom wall of the battery tray, causing the limit block 219 to rotate to the right in the hole groove of the upper side wall of the second placement plate 218, so that the limit block 219 shrinks back into the hole groove of the second placement plate 218. When the first placement plate 215 and the second placement plate 218 completely enter the bottom of the battery tray, the limit block 219 will rebound through the spring at the bottom, causing the limit block 219 to reset. When pulling the battery tray, the right side wall of the limit block 219 will contact the left side wall of the bottom of the battery tray, and at the same time, the left side wall of the limit block 219 will contact and restrict the inner wall of the hole groove on the upper side wall of the second placement plate 218 to prevent the limit block 219 from rotating to the left and support the left side of the battery tray when pulling, so as to pull the battery tray back to the upper side wall of the tray 211

[0045] like Figure 10 - Figure 12 As shown, a bracket 4 is fixedly connected to the top of the left side wall of the conveyor belt 1. The interior of the bracket 4 is arranged corresponding to the support plate 211. The left side wall of the bracket 4 is fixedly connected to the second device box 5. The bracket 4 is arranged to connect the loading area and the second device box 5 on the left side. Two electric push rods 6 are arranged inside the left side wall of the bracket 4 to protect the outside of the electric push rod 6 and enable the telescopic end of the electric push rod 6 to slide inside the bracket 4 and the second device box 5.

[0046] The outer sides of the telescopic ends of the two electric push rods 6 are rotatably connected to the second hinge frames 7, the insides of the two second hinge frames 7 are rotatably connected to the first support rod 8, the tops of the two first support rods 8 are rotatably connected to the I-shaped blocks 10, the front and rear sides of the middle part of each first support rod 8 are rotatably connected to the support blocks 9, and the left side walls of each two support blocks 9 are fixedly connected to the interior of the second device box 5, extending to the left through the telescopic end of the electric push rod 6. Since the outer side of the telescopic end is rotatably connected to the first support rod 8 through the second hinge frame 7, as the electric push rod 6 is extended, the middle part of the first support rod 8 rotates around the connection point with the support block 9, and the support block 9 provides stable support and rotation fulcrum for the first support rod 8, ensuring the smoothness and directionality of its movement.

[0047] The right side of the two I-shaped blocks 10 is rotatably connected to the second support rod 11, and the right side walls of the two second support rods 11 are fixedly connected to a push plate 12. The bottom of the push plate 12 is set on the upper side wall of the bracket 4. During the rotation of the first support rod 8, its top drives the I-shaped block 10 to move to the right, and the second support rod 11 rotatably connected inside the I-shaped block 10 also moves accordingly. Since the right side wall of the second support rod 11 is fixedly connected to the push plate 12, the bottom of the push plate 12 contacts the upper side wall of the bracket 4 and is supported and guided by the bracket 4. Therefore, the push plate 12 will slide to the right along the upper surface of the bracket 4 under the push of the second support rod 11, and push the battery tray located in the area of the bracket 4 to the right onto the conveyor belt 1.

[0048] like Figure 13 - Figure 16 As shown, the right side wall of the conveyor belt 1 is fixedly connected with a conversion platform 13. When the battery is conveyed to the next conveyor belt, it is directly conveyed. The position of the positive and negative poles of the battery inside the battery tray may change, and the position of the battery tray is adjusted by the conversion platform 13 and the device on the top. The top of the conversion platform 13 is fixedly connected with a support frame 14, and the interior of the support frame 14 is provided with a rotating clamping mechanism 3;

[0049] The rotating clamping mechanism 3 includes: a second connecting plate 301, a third hydraulic rod 302, four connecting blocks 307 and a second motor 311. The second connecting plate 301 is arranged at the bottom of the support frame 14. The bottom wall of the third hydraulic rod 302 is fixedly connected to the upper side wall of the second connecting plate 301. The top of the telescopic end of the third hydraulic rod 302 is fixedly connected to the third connecting plate 303. The bottom of the third connecting plate 303 is fixedly connected to the first articulated frame 304. The inside of the four first articulated frames 304 are all rotatably connected to the pull rod 305. The telescopic end of the third hydraulic rod 302 is extended to push the third connecting plate 303 to move upward. As the third connecting plate 303 rises, the four first articulated frames 304 at its bottom drive the pull rod 305 rotatably connected to it to move.

[0050] The outer sides of the bottoms of the four pull rods 305 are rotatably connected to the second articulated frame 306, the bottom walls of the second connecting plates 301 are fixedly connected to the second guide rails 309, the outer sides of the four second guide rails 309 are slidably connected to the moving blocks 308, the upper side walls of the four connecting blocks 307 are fixedly connected to the upper side walls of the four moving blocks 308, the bottom walls of the four second articulated frames 306 are fixedly connected to the upper side walls of the connecting blocks 307, and are rotatably connected to the second articulated frame 306 through the outer sides of the bottoms of the pull rods 305, and the bottom walls of the second articulated frames 306 are fixedly connected to the connecting blocks 307, and the upper side walls of the connecting blocks 307 are fixedly connected to the moving blocks 308 sliding on the outer sides of the second guide rails 309. Therefore, under the pulling of the pull rods 305, the moving blocks 308 will slide outward along the second guide rails 309. The bottom walls of the four connecting blocks 307 are fixedly connected with clamping blocks 310. When the movable block 308 slides outward, the connecting block 307 also moves outward, so that the clamping blocks 310 fixed on the bottom walls of the connecting block 307 move away from each other, thereby expanding the distance between the clamping blocks 310. When the battery tray is transported to the upper side wall of the conversion platform 13 through the conveyor belt 1 to clamp the battery tray, the telescopic end of the third hydraulic rod 302 begins to contract, driving the third connecting plate 303 to descend. Through the linkage of the pull rod 305 and the second articulated frame 306, the clamping blocks 310 will approach each other, and finally clamp the material tightly to complete the clamping action of the material.

[0051] like Figure 17 - Figure 18As shown, the bottom wall of the second motor 311 is fixedly connected to the hole groove of the upper side wall of the third connecting plate 303, and a top cover 312 is provided on the top of the hole groove of the upper side wall of the third connecting plate 303. The output end of the second motor 311 is fixedly connected to the rotating rod 313. The second motor 311 is arranged inside the third connecting plate 303, and the hole groove on the top of the third connecting plate 303 is closed by the top cover 312 to prevent the second motor 311 from falling off. The upper side wall of the third connecting plate 303 is provided with a connecting rod 17. The top end of the rotating rod 313 passes through the inside of the top cover 312 and is fixedly connected to the bottom end of the connecting rod 17. The outer top end of the connecting rod 17 is fixedly connected to the sleeve 15. The outer top end of the sleeve 15 is fixedly connected to the connecting ring 16. The connecting ring 16 is connected to the inner top wall of the support frame 14. The top end of the rotating rod 313 passes through the top cover 312 and is fixedly connected to the telescopic end of the connecting rod 17. Since the outer top end of the connecting rod 17 is fixedly connected to the sleeve The outer side of the top of the cylinder 15 and the sleeve 15 is fixedly connected with a connecting ring 16, and the connecting ring 16 is rotatably connected to the top wall of the support frame 14, so when the rotating rod 313 rotates, it will drive the connecting rod 17, the sleeve 15 and the connecting ring 16 to rotate around the axis of the connecting ring 16, and the clamping block 310 clamping the material is in a linkage state with the connecting rod 17 through the third connecting plate 303 and other components, so the clamping block 310 will rotate with the rotation of the connecting rod 17, thereby realizing the rotation operation of the clamped material.

[0052] It should be noted that the present invention is a material collection system for a lithium battery production line. First, the first motor 203, the first hydraulic rod 213, the second hydraulic rod 217, the electric push rod 6, the third hydraulic rod 302 and the second motor 311 are connected to an external power supply and a control end, and the device is controlled and operated through a program on the control end.

[0053] When the system is started, the first motor 203 located on the front and rear sides of the first device box 202 begins to operate. The output end of the first motor 203 drives the first rotating shaft 204 to rotate, thereby causing the tensioning pulley 205 fixed to the other end of the first rotating shaft 204 to rotate synchronously. Since the interiors of the two first guide rails 201 are both slidably connected to the belt 206, and the bottom of the belt 206 is set inside the tensioning pulley 205, the rotation of the tensioning pulley 205 drives the belt 206 to circulate within the first guide rail 201. The left portion of the belt 206 is threadedly connected to the interior of the first slider 207 through the coupling block 208. Therefore, the movement of the belt 206 drives the first slider 207 to slide up and down along the first guide rail 201. The pulley 209 fixed to the right side wall of the first slider 207 slides in the hole grooves on the front and rear sides of the first guide rail 201, providing auxiliary support and guidance, ensuring that the first slider 207 moves up and down smoothly.

[0054] The first connecting plate 210 fixed to the left side walls of the two first sliders 207 and the supporting plate 211 connected to the left side wall of the first connecting plate 210 will rise and fall together with the first slider 207. When loading is required, the supporting plate 211 is lowered to the material placement position. When batteries need to be loaded, the first hinge frame 214 on the outer side of the telescopic end of the first hydraulic rod 213 inside the supporting plate 211 is connected to the first placement plate 215. When the first hydraulic rod 213 is activated, it is connected to the first placement plate 215 through the first hinge frame 214, driving the first placement plate 215 to slide left and right, so that the first placement plate 215 moves toward the battery tray on the left.

[0055] When the first placement plate 215 is sliding, the second sliders 216 on the front and rear sides of the first placement plate 215 will slide in the track grooves 212 on the front and rear inner walls of the support plate 211 to provide stable sliding and support effects for the first placement plate 215 during sliding. In addition, when the length of the first placement plate 215 cannot contact the battery tray on the left, the second placement plate 218 will be driven to slide by the second hydraulic rod 217 inside the first placement plate 215 to extend the length of the first placement plate 215 to pull the battery tray, etc.

[0056] When the first placing plate 215 and the second placing plate 218 enter the bottom of the battery tray, the limit block 219 inside the second placing plate 218 will contact the bottom wall of the battery tray, causing the limit block 219 to rotate to the right in the upper side wall hole groove of the second placing plate 218, so that the limit block 219 retracts into the hole groove of the second placing plate 218. When the first placing plate 215 and the second placing plate 218 completely enter the bottom of the battery tray, the limit block 219 will rebound through the spring at the bottom, so that the limit block 219 is reset. When the battery tray is pulled out, the right side wall of the limit block 219 will contact the left side wall of the bottom of the battery tray, and at the same time, the left side wall of the limit block 219 will contact and limit the inner wall of the hole groove on the upper side wall of the second placing plate 218 to prevent the limit block 219 from rotating to the left and support the left side of the battery tray when being pulled, so as to pull the battery tray back to the upper side wall of the tray 211.

[0057] Once the battery trays and other materials are loaded, the first motor 203 rotates in reverse, driving the belt 206 in the opposite direction, thereby raising the pallet 211 and the materials on it to the same level as the conveyor belt 1. Finally, the materials are smoothly conveyed to the conveyor belt 1, completing the entire loading process and providing a material base for subsequent processes in the lithium battery production line, ensuring the efficient and stable operation of the production line.

[0058] When the battery tray is raised by the lifting and loading mechanism 2 to a position flush with the conveyor belt 1 and the upper side wall of the bracket 4, the two electric push rods 6 inside the left side of the bracket 4 begin to operate. The telescopic end of the electric push rod 6 extends to the left. Because the outer side of the telescopic end is rotatably connected to the first support rod 8 via the second hinge frame 7, as the electric push rod 6 extends, the middle part of the first support rod 8 rotates around the connection point with the support block 9. The support block 9 provides stable support and rotation fulcrum for the first support rod 8, ensuring its smooth and directional movement.

[0059] During the rotation of the first support rod 8, its top drives the I-shaped block 10 to move to the right, and the second support rod 11 rotatably connected inside the I-shaped block 10 also moves accordingly. Since the right side wall of the second support rod 11 is fixedly connected to the push plate 12, the bottom of the push plate 12 is in contact with the upper side wall of the bracket 4 and is supported and guided by the bracket 4. Therefore, the push plate 12 will slide to the right along the upper surface of the bracket 4 under the push of the second support rod 11, and push the battery tray located in the area of the bracket 4 to the right onto the conveyor belt 1, ensuring that the material can be placed on the conveyor belt 1 accurately and stably, so that the subsequent conveyor belt 1 can smoothly transport the material to the next production link.

[0060] When the material needs to be clamped and repositioned, the third hydraulic rod 302 begins operation. The telescopic end of the third hydraulic rod 302 extends, pushing the third connecting plate 303 upward. As the third connecting plate 303 rises, the four first articulated frames 304 at its bottom drive the pull rods 305, which are pivotally connected to it. Because the bottom outer sides of the pull rods 305 are pivotally connected to the second articulated frames 306, the bottom wall of which is fixedly connected to the connecting block 307. The upper side wall of the connecting block 307 is fixedly connected to the movable block 308, which slides on the outside of the second guide rail 309. Therefore, under the pull of the pull rods 305, the movable block 308 slides outward along the second guide rail 309.

[0061] When the movable block 308 slides outward, the connecting block 307 also moves outward, causing the clamping blocks 310 fixed to the bottom wall of the connecting block 307 to move away from each other, thereby increasing the distance between the clamping blocks 310 and preparing to clamp the material. Subsequently, the material to be processed is placed in a suitable position between the clamping blocks 310. At this time, the telescopic end of the third hydraulic rod 302 begins to retract, driving the third connecting plate 303 to descend. Through the linkage of the pull rod 305 and the second articulated frame 306, the clamping blocks 310 will move closer to each other, eventually clamping the material tightly and completing the material clamping action.

[0062] After the material is successfully clamped by the clamping block 310, the second motor 311 starts to work. The output end of the second motor 311 drives the rotating rod 313 to rotate. The top end of the rotating rod 313 passes through the top cover 312 and is fixedly connected to the telescopic end of the connecting rod 17. Since the top outer side of the connecting rod 17 is fixedly connected to the sleeve 15, the top outer side of the sleeve 15 is fixedly connected to the connecting ring 16, and the connecting ring 16 is rotatably connected to the inner side of the top wall of the support frame 14, when the rotating rod 313 rotates, it will drive the connecting rod 17, the sleeve 15 and the connecting ring 16 to rotate around the axis of the connecting ring 16. The clamping block 310, which clamps the material, is in a linked state with the connecting rod 17 through the third connecting plate 303 and other components. Therefore, the clamping block 310 rotates with the rotation of the connecting rod 17, thereby realizing the rotation operation of the clamped material.
