Description

Technical Field

[0001] This utility model relates to the field of battery cells, and in particular to a novel turret-type core clamping and flipping mechanism. Background Technology

[0002] With the energy crisis and environmental problems becoming increasingly severe, and with the country's strong support for the new energy industry, key technologies for power winding cores have gradually matured, and various types of power winding cores have been widely used in electric cars, electric motorcycles, electric bicycles, solar energy, mobile communication terminal products, and energy storage products.

[0003] The core flipping mechanism is an essential component of automated battery production lines. During the welding of positive and negative current collectors to the core, it needs to be flipped to facilitate processing of both ends. Traditional core clamping fixtures use electric or pneumatic grippers to hold the core; excessive clamping force can damage the core, while insufficient force can cause it to slip during flipping, posing a risk of core falling due to power or gas outages. Furthermore, the flipping efficiency of these mechanisms cannot meet the production speed requirements of high-volume equipment, leading to reduced production speed and severely impacting the production indicators of automated battery production lines. This hinders mass production and fails to meet customer efficiency demands. Therefore, a novel turret-type core clamping and flipping mechanism is proposed. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A novel turret-type core clamping and flipping mechanism includes a double-layer support plate. A rotating shaft is vertically arranged in the middle of the double-layer support plate and rotates on its own axis. A hinge shaft fixing frame is vertically arranged around the outer part of the top of the double-layer support plate, and a hinge shaft is rotatably inserted through the middle of the hinge shaft fixing frame. A gear shaft is movably arranged at the connection between the hinge shaft fixing frame and the double-layer support plate, thereby driving the hinge shaft fixing frame to rotate at the outer part of the top of the double-layer support plate. A gripper control rod is synchronously connected to one end of the hinge shaft, and the gripper control rod is horizontally located on the back of the hinge shaft fixing frame. Gripper blocks are driven to both sides of the other end of the gripper control rod, and the gripper blocks are vertically distributed on both sides of the front side of the hinge shaft fixing frame. A core placement seat is vertically arranged around the outer part of the bottom of the double-layer support plate, and a core is vertically placed on the top of the core placement seat.

[0006] Preferably, a lower cam turntable and an upper cam turntable are respectively horizontally mounted at the upper and lower ends of the rotating shaft, and the lower cam turntable and the upper cam turntable are parallel to each other with respect to the double-layer support plate. The lower cam turntable and the upper cam turntable rotate on their own axes on the upper and lower surfaces of the double-layer support plate. A plurality of upper cam pressure rods are provided between the upper cam turntable and the double-layer support plate, and the plurality of upper cam pressure rods are vertically distributed around the bottom end of the upper cam turntable. The plurality of upper cam pressure rods are engaged with the upper cam turntable through cam transmission, and the plurality of upper cam pressure rods are in transmission contact with the gripper control rod.

[0007] Preferably, each of the plurality of upper cam pressure rods is provided with an upper ejector branch between it and the gripper control rod, and the upper ejector branch is vertically located at the bottom end of the plurality of upper cam pressure rods, and the upper ejector branch makes transmission contact with the gripper control rod.

[0008] Preferably, a plurality of first lower cam pressure rods and a plurality of second lower cam pressure rods are provided between the lower cam turntable and the double-layer support plate. The plurality of first lower cam pressure rods and the plurality of second lower cam pressure rods are vertically arranged around the top of the lower cam turntable. The plurality of first lower cam pressure rods and the plurality of second lower cam pressure rods are respectively engaged with the lower cam turntable through cam transmission. The plurality of first lower cam pressure rods are in transmission contact with the gripper control rod. The top of each of the plurality of second lower cam pressure rods is vertically provided with a rack. The racks are all in the same direction of movement as the plurality of second lower cam pressure rods, and the racks are meshed with the gear shaft.

[0009] Preferably, a guide rail fixing frame is provided between the gripper block and the hinge shaft fixing frame, and the guide rail fixing frame is horizontally mounted on the front side of the hinge shaft fixing frame. A guide rail is horizontally arranged on the front side of the guide rail fixing frame, and the gripper blocks are vertically distributed on both sides of the front side of the guide rail, and the gripper blocks move horizontally on the guide rail.

[0010] Preferably, a gripper blocking block is provided between the gripper blocks, and the gripper blocking block is vertically located at the middle position of the front side of the guide rail.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the core is placed vertically at the top of the core placement seat, and the gripper control rod moves downward and drives the hinge shaft to rotate, thereby driving the gripper blocks to move from the middle position of the hinge shaft fixing frame to both sides, so that the gripper blocks are in the open state and the core is vertically located between the gripper blocks. At this time, due to the elastic action of the tension spring, the gripper blocks quickly and elastically reset and clamp the core, and the gripper control rod resets again. When the gripper blocks clamp and fix the core, the gear shaft rotates and drives the hinge shaft fixing frame to rotate, thereby flipping the clamped core. After flipping, the core is vertically placed back on the core placement seat. Furthermore, the gripper control lever is re-driven downwards, causing the hinge shaft to rotate and thus moving the gripper blocks from the center of the hinge shaft fixing frame to both sides. This opens the gripper blocks and releases the core, facilitating subsequent core processing. The clamping fixture structure has been optimized, with cams controlling the opening and closing of the grippers. A blocking block is added between the two gripper blocks, with the size of the blocking block designed according to the core size to limit the gripper closing distance, avoiding the risk of damaging the core or the core slipping. The structure is simple and compact, occupying little space and facilitating installation and maintenance. It also increases the speed of core flipping and conveying, ensuring equipment production efficiency, saving production time and costs, and benefiting mass production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-4In this embodiment of the present invention, a novel turret-type core clamping and flipping mechanism includes a double-layer support plate 3. A rotating shaft 1 is vertically arranged in the middle of the double-layer support plate 3, and the rotating shaft 1 rotates in the middle of the double-layer support plate 3. A hinge shaft fixing frame 13 is vertically arranged around the outer part of the top of the double-layer support plate 3, and a hinge shaft 19 is rotatably inserted through the middle of the hinge shaft fixing frame 13. A gear shaft 16 is movably arranged at the connection between the hinge shaft fixing frame 13 and the double-layer support plate 3, thereby driving the hinge shaft through the gear shaft 16. The fixing frame 13 rotates at the outer part of the top of the double-layer support plate 3. One end of the hinge shaft 19 is synchronously connected to a gripper control rod 15, and the gripper control rod 15 is laterally located at the back of the hinge shaft fixing frame 13. The other end of the gripper control rod 15 is driven to connect gripper blocks 8 on both sides, and the gripper blocks 8 are vertically distributed on both sides of the front side of the hinge shaft fixing frame 13. The gripper blocks 8 translate on both sides of the front side of the hinge shaft fixing frame 13, and tension springs (not shown in the figure) are provided between the gripper blocks 8. The outer part of the bottom end of the double-layer support plate 3 A core placement seat 5 is vertically arranged around each of the core placement seats, and the core placement seats 5 and the gripper blocks 8 are parallel to each other. A core 9 is vertically placed on the top of the core placement seat 5. When the core 9 is vertically placed on the top of the core placement seat 5, the gripper control rod 15 moves downward and drives the hinge shaft 19 to rotate, thereby driving the gripper blocks 8 to move from the middle position of the hinge shaft fixing frame 13 to both sides, so that the gripper blocks 8 are in the open state and the core 9 is vertically located between the gripper blocks 8. At this time, due to the elastic action of the tension spring, the gripper blocks 8 quickly and elastically return to their original position and grip the core 9. When clamping and resetting the gripper control lever 15, and when the gripper block 8 clamps and fixes the core 9, the gear shaft 16 rotates and drives the hinge shaft fixing frame 13 to rotate, thereby flipping the gripped core 9. After flipping, the core 9 is placed vertically on the core placement seat 5 again, and the gripper control lever 15 is driven to move downward and drive the hinge shaft 19 to rotate, thereby driving the gripper block 8 to move from the middle position of the hinge shaft fixing frame 13 to both sides, so that the gripper block 8 is in the open state and releases the core 9 for subsequent processing of the core 9.

[0021] The upper and lower ends of the rotating shaft 1 are respectively horizontally fitted with a lower cam turntable 4 and an upper cam turntable 12, which are parallel to each other with respect to the double-layer support plate 3. The lower cam turntable 4 and the upper cam turntable 12 rotate on the upper and lower surfaces of the double-layer support plate 3, respectively. A plurality of upper cam pressure rods 10 are provided between the upper cam turntable 12 and the double-layer support plate 3, and the plurality of upper cam pressure rods 10 are vertically distributed around the bottom of the upper cam turntable 12. The plurality of upper cam pressure rods 10 are engaged with the upper cam turntable 12 through cam transmission, and the plurality of upper cam pressure rods 10 are in transmission contact with the gripper control rod 15. Thus, when the upper cam turntable 12 rotates, it drives the plurality of upper cam pressure rods 10 to move up and down on the top of the double-layer support plate 3 and at the same time repeatedly presses the gripper control rod 15, thereby driving the gripper block 8 to open and close.

[0022] Each of the plurality of upper cam pressure rods 10 is provided with an upper throwing branch seat 11 between it and the gripper control rod 15. The upper throwing branch seat 11 is vertically located at the bottom of the plurality of upper cam pressure rods 10. The upper throwing branch seat 11 is in transmission contact with the gripper control rod 15. Thus, when the plurality of upper cam pressure rods 10 move up and down, they drive the upper throwing branch seat 11 to move up and down and press the gripper control rod 15 down. The hinge shaft 19 rotates, causing the gripper block 8 to move to both sides of the hinge shaft fixing frame 13 and separate.

[0023] A plurality of first lower cam pressure rods 6 and a plurality of second lower cam pressure rods 14 are arranged between the lower cam turntable 4 and the double-layer support plate 3. The first lower cam pressure rods 6 and the second lower cam pressure rods 14 are vertically arranged around the top of the lower cam turntable 4. The first lower cam pressure rods 6 and the second lower cam pressure rods 14 are engaged with the lower cam turntable 4 via cam transmission. The first lower cam pressure rods 6 are in transmission contact with the gripper control rod 15. Each of the second lower cam pressure rods 14 has a rack 17 vertically mounted at its top, and the racks 17 move in the same direction as the second lower cam pressure rods 14. Furthermore, the rack 17 and the gear shaft 16 mesh with each other, so that when the lower cam turntable 4 rotates, it drives several second lower cam pressure rods 14 to move up and down at the bottom of the double-layer support plate 3 and simultaneously drives the rack 17 to move up and down. Thus, the up and down movement of the rack 17 drives the gear shaft 19 to rotate, causing the hinge shaft fixing frame 13, along with the gripper block 8 and the upper cam pressure rod 10, to flip their positions at the bottom of the double-layer support plate 3. When the lower cam turntable 4 rotates, it drives several upper cam pressure rods 10 to move up and down at the bottom of the double-layer support plate 3 and simultaneously repeatedly lifts the flipped gripper control rod 15, thereby driving the gripper block 8 to open and close.

[0024] A guide rail fixing frame 7 is provided between the gripper block 8 and the hinge shaft fixing frame 13. The guide rail fixing frame 7 is horizontally mounted on the front side of the hinge shaft fixing frame 13. A guide rail 18 is horizontally arranged on the front side of the guide rail fixing frame 7. The gripper blocks 8 are vertically distributed on both sides of the front side of the guide rail 18. The gripper blocks 8 move horizontally on the guide rail 18, thereby ensuring that the gripper blocks 8 remain stable when moving horizontally on both sides of the front side of the hinge shaft fixing frame 13 through the guide rail 18.

[0025] A gripper blocking block (not shown in the figure) is provided between the gripper blocks 8, and the gripper blocking block is vertically located at the middle position of the front side of the guide rail 18. The size of the blocking block is designed according to the size of the core 9 to limit the closing distance of the gripper blocks 8 and avoid the risk of pinching the core 9 and the core 9 slipping.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
