Description

Technical Field

[0001] This utility model relates to the field of graphitization of lithium battery negative electrodes, specifically to a graphitization box-type furnace cover gripping mechanism and graphitization device. Background Technology

[0002] Graphite is currently the most commonly used material for lithium-ion battery anodes, and high-temperature graphitization in a box furnace is a crucial process for producing graphite anode materials. During the graphitization process of anode materials in a box furnace, due to the prolonged high temperature, the raw materials undergo irregular settling, resulting in irregular settling and angular deflection of the furnace cover. After the graphitization process is complete, the furnace cover needs to be opened to extract the finished graphite product. However, due to the irregular settling and random deflection of the cover, suction cups and ordinary hooks cannot effectively grasp it. Existing technology often involves manual removal of the cover. However, although the furnace is cooled after the high-temperature reaction, the ambient temperature remains high, resulting in a harsh working environment for manual removal. Furthermore, the cover is large and heavy, requiring multiple people to work together, leading to high labor costs and low efficiency. Utility Model Content

One end of the first arm is hinged to one end of the second arm, and the other end of the first arm is connected to the sleeve. The other end of the second arm is connected to the telescopic rod. The gripper drive includes a gripper cylinder. The cylinder body of the gripper cylinder is installed on the floating frame, and the piston rod of the gripper cylinder is connected to the telescopic rod.

[0006] As a further improvement to the above technical solution, a tapered guide block is provided at the lower end of the telescopic rod, and the apex of the guide block faces downward.

[0007] As a further improvement to the above technical solution, two first guide members are provided, which are arranged opposite each other along the Y direction; two second guide members are provided, which are arranged opposite each other along the X direction; a first through hole is provided on the frame, which is located between the two second guide members; a second through hole is provided on the floating frame, which is located between the two first guide members; a sleeve passes through the first through hole, and one end of the sleeve is connected to the second through hole; and a telescopic rod passes through the second through hole.

[0008] As a further improvement to the above technical solution, the first guide member includes a first slider and a first guide rail arranged along the X direction, the second guide member includes a second slider and a second guide rail arranged along the Y direction, the second guide rail is fixedly installed on the frame, the second slider is slidably installed on the second guide rail, the first guide rail is fixedly installed on the second slider, the first slider is slidably installed on the first guide rail, and the floating frame is fixedly installed on the first slider.

[0009] As a further improvement to the above technical solution, the reset component includes two reset cylinders arranged opposite to each other. The cylinder bodies of the two reset cylinders are both mounted on the frame, and the extension and retraction directions of their piston rods are opposite. The floating frame is located between the two reset cylinders. The floating frame has an abutment plate on its side facing the reset cylinder. The abutment plate has a V-shaped notch on its side facing the reset cylinder. The piston rod of the reset cylinder is connected to a conical abutment block, and the apex of the abutment block faces the V-shaped notch.

[0010] As a further improvement to the above technical solution, a vertical rotating column is provided at the apex of the abutment block, and a roller is rotatably connected to the rotating column.

[0011] As a further improvement to the above technical solution, four leveling rods are provided, arranged in a square pattern, and the hook is located in the middle of the four leveling rods; the leveling drive includes two leveling cylinders, the cylinder bodies of the two leveling cylinders are mounted on the frame, and the piston rods of the two leveling cylinders are connected to connecting plates, which are connected between two adjacent leveling rods.

[0012] As a further improvement to the above technical solution, a guide sleeve is provided on the frame, and the leveling rod passes through the guide sleeve; the lower end of the leveling rod is wrapped with a columnar rubber sleeve, and the cross-sectional area of ​​the rubber sleeve is larger than the cross-sectional area of ​​the leveling rod.

[0014] The beneficial effects of this utility model are as follows: After the graphitization reaction in the box furnace is completed, the mechanism is moved above the cover plate by the drive frame. Under the action of the first and second guide members, the floating frame can move in the X and Y directions. When the cover plate experiences irregular settlement and random deflection, the hook and the connecting hole cannot be perfectly aligned. The floating frame can drive the hook to move in the X and Y directions so that the hook can extend into the connecting hole. The hook is then driven by the gripper drive to hook the cover plate. Then, the leveling drive drives the leveling rod downward to abut against the cover plate so that the cover plate is kept in a horizontal position. Under the action of the reset member, the floating frame moves in both the X and Y directions until the floating frame is in a horizontal and centered position. At this time, the cover plate connected to the hook is directly below the entire mechanism. The drive frame moves towards the cover plate placement point. After reaching the cover plate placement point, the leveling drive drives the leveling rod to retract, and the gripper drive drives the hook to release the cover plate, thus completing the entire process of picking up and placing the cover plate. The hook of this mechanism can adapt to the position of the cover plate. Even if the cover plate experiences irregular settlement or random deflection, the hook can still effectively pick up the cover plate, solving the problem of difficulty in picking up the cover plate of existing box furnaces.

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Please see Figures 1-2 A preferred embodiment of this utility model provides a graphitization box furnace cover plate gripping mechanism 1, including a frame 11, a leveling component 12, a floating component 13, and a gripper component 14. The gripper component 14 is used to grip or release the cover plate 2. The leveling component 12 is used to keep the cover plate 2 gripped by the gripper component 14 horizontal. The leveling component 12 can also cooperate with the gripper component 14 to fix the cover plate 2 to prevent the cover plate 2 from shaking during movement. The floating component 13 enables the gripper component 14 to adapt to the position of the cover plate 2 so that the gripper component 14 can grip the cover plate 2.

[0026] For details, please see Figures 2-3The gripper assembly 14 includes a hook 141 and a gripper drive 142 mounted on the floating frame 131. The gripper drive 142 drives the hook 141 to hook or release the cover plate 2 through the connection hole 212 provided on the cover plate 2. The hook 141 includes a sleeve 143, a telescopic rod 144, a first arm 145, and a second arm 146. The sleeve 143 is fixedly mounted on the floating frame 131 in a vertical direction. The telescopic rod 144 is slidably disposed inside the sleeve 143. One end of the first arm 145 is hinged to one end of the second arm 146, and the other end of the first arm 145 is connected to the sleeve 143. The other end of the second arm 146 is connected to the telescopic rod 144. The gripper drive 142 includes a gripper cylinder 148, the cylinder body of which is mounted on the floating frame 131. 1. The piston rod of the gripper cylinder 148 is connected to the telescopic rod 144. When the piston rod of the gripper cylinder 148 extends, the second arm 146 extends downward, and the angle between the first arm 145 and the second arm 146 increases, so that the two can be connected in a straight line. At this time, the entire hook 141 can be passed through the connecting hole 212 on the cover plate 2. Then the piston rod of the gripper cylinder 148 retracts, and the angle between the first arm 145 and the second arm 146 decreases until the first arm 145 abuts against the lower surface of the cover plate 2, thereby hooking the cover plate 2. Then the external robotic arm drives the entire device to move towards the cover plate placement point. During the movement of the robotic arm, the gripper cylinder 148 continuously provides an upward pulling force, so that the hook 141 can always hook the cover plate 2. The structure is simple and highly reliable.

[0027] In addition, a tapered guide block 147 is provided at the lower end of the telescopic rod 144, with the apex of the guide block 147 facing downwards. The tip of the guide block 147 can play a guiding role, reducing the difficulty of aligning with the connection hole 212 on the cover plate 2. Furthermore, the tip of the guide block 147 does not need to be completely aligned with the connection hole 212. Under the action of the floating component 13, the position can be automatically adjusted so that the guide block 147 extends into the connection hole 212, and then the position of the cover plate 2 can be adjusted by the leveling component 12.

[0028] Please see Figure 2 In this embodiment, the leveling component 12 includes a leveling drive 121 and several vertically arranged leveling rods 122. The leveling drive 121 is used to drive the leveling rods 122 to rise and fall. There are four leveling rods 122 arranged in a square. The hook 141 is located in the middle of the four leveling rods 122. When the hook 141 hooks the cover plate 2, the four leveling rods 122 can press down on the four sides of the cover plate 2 respectively. The cover plate 2 is subjected to uniform force on the four sides, so that the cover plate 2 is in a horizontal position and can prevent the cover plate 2 from flipping.

[0029] The leveling drive unit 121 includes two leveling cylinders 123. The cylinder bodies of the two leveling cylinders 123 are both mounted on the frame 11. The piston rods of the two leveling cylinders 123 are connected to connecting plates 124. The connecting plates 124 are connected between two adjacent leveling rods 122. The four leveling rods 122 are divided into two groups. The two leveling rods 122 in the same group are driven by the same leveling cylinder 123, which ensures the synchronicity of the lifting and lowering of the two leveling rods 122 in the same group and further improves the uniformity of the force on the cover plate 2.

[0030] Furthermore, the frame 11 is equipped with four guide sleeves 111, and four leveling rods 122 are respectively inserted through the four guide sleeves 111. The cooperation between the guide sleeves 111 and the leveling rods 122 ensures that the leveling rods 122 move along a predetermined path, avoiding deviation or jamming. The lower end of the leveling rod 122 is wrapped with a columnar rubber sleeve 125. The cross-sectional area of ​​the rubber sleeve 125 is larger than that of the leveling rod 122. The rubber sleeve 125 is designed to increase the contact area between the leveling rod 122 and the cover plate 2, disperse pressure, reduce local pressure at the contact point, and the rubber sleeve 125 is made of soft material, which can prevent scratching the surface of the cover plate 2.

[0031] Please see Figure 4 The floating assembly 13 includes a floating frame 131, a first guide 132 arranged in the X direction, a second guide 133 arranged in the Y direction, and a reset member 134. The second guide 133 is mounted on the frame 11, the first guide 132 is slidably disposed on the second guide 133, and the floating frame 131 is slidably disposed on the first guide 132. Under the action of the first guide 132 and the second guide 133, the floating frame 131 can move in the X and Y directions. When the cover plate 2 experiences irregular settlement and random deflection, the hook 141 and the connecting hole 212 cannot be completely aligned. The floating frame 131 can drive the hook 141 to move in the X and Y directions so that the hook 141 can extend into the connecting hole 212, thereby the hook 141 can also effectively hook the cover plate 2, solving the problem of difficulty in removing the cover plate of the existing box furnace.

[0032] In this embodiment, two first guide members 132 are provided, which are arranged opposite each other along the Y direction. Two second guide members 133 are provided, which are arranged opposite each other along the X direction. The movement of the floating frame 131 in both the X and Y directions is guided by the dual guide assembly. The dual guide assembly can evenly distribute the load of the floating frame 131, reduce deformation or wear caused by stress concentration, and prevent the floating frame 131 from tilting or deflecting during movement, thus ensuring the stability of the linear movement of the floating frame 131.

[0033] Please see Figure 4The frame 11 is provided with a first through hole 112, which is located between two second guide members 133. The floating frame 131 is provided with a second through hole 135, which is located between two first guide members 132. The sleeve 143 passes through the first through hole 112, and one end of the sleeve 143 is connected to the second through hole 135. The telescopic rod 144 passes through the second through hole 135. The hook 141 can only move within the first through hole 112, which restricts the range of motion of the hook 141 and prevents the hook 141 from exceeding the control range of the reset member 134.

[0034] Furthermore, the first guide member 132 includes a first slider 137 and a first guide rail 136 arranged along the X direction, and the second guide member 133 includes a second slider 139 and a second guide rail 138 arranged along the Y direction. The second guide rail 138 is fixedly mounted on the frame 11, the second slider 139 is slidably mounted on the second guide rail 138, the first guide rail 136 is fixedly mounted on the second slider 139, the first slider 137 is slidably mounted on the first guide rail 136, and the floating frame 131 is fixedly mounted on the first slider 137. The cooperation between the first slider 137 and the first guide rail 136 can reduce the friction of the floating frame 131 moving in the X direction, making the movement of the floating frame 131 smoother. The cooperation between the second slider 139 and the second guide rail 138 can reduce the friction of the first guide rail 136 moving in the Y direction, making the movement of the first guide rail 136 smoother.

[0035] Please see Figures 4-5 The reset component 134 is used to adjust the floating frame 131 to a centered position. The reset component 134 includes two oppositely arranged reset cylinders 130. The cylinder bodies of the two reset cylinders 130 are both mounted on the frame 11, and the extension and retraction directions of their piston rods are opposite. The floating frame 131 is located between the two reset cylinders 130. An abutment plate 113 is provided on the side of the floating frame 131 facing the reset cylinder 130. A V-shaped notch 114 is provided on the side of the abutment plate 113 facing the reset cylinder 130. The piston of the reset cylinder 130... The rod is connected to a conical abutment block 115, with the apex of the abutment block 115 facing the V-shaped notch 114. The piston rods of the two reset cylinders 130 extend synchronously, driving the abutment block 115 to move toward the V-shaped notch 114. In the initial state, the floating frame 131 is in the offset position. The abutment block 115 slides inward along the inner wall of the V-shaped notch 114, driving the floating frame 131 to move horizontally until the apex of the abutment block 115 abuts against the bottom of the V-shaped notch 114. At this time, the floating frame 131 returns to the center position.

[0036] Please see Figure 5In this embodiment, a vertical rotating column 116 is provided at the apex of the abutment block 115, and a roller 117 is rotatably connected to the rotating column 116. The rotation of the roller 117 can reduce the friction between the abutment block 115 and the V-shaped notch 114, reduce the wear between the two, and the abutment block 115 moves faster relative to the inner wall of the V-shaped notch 114, thus improving the movement efficiency.

[0037] Please see Figure 1 The preferred embodiment of this utility model also provides a graphitization device, including a box furnace, a robotic arm (not shown in the figure), and two graphitization box furnace cover plate gripping mechanisms 1 described in the above embodiment. The box furnace includes a cover plate 2 and a box body with an opening (not shown in the figure), with the cover plate 2 covering the opening of the box body. Two frames 11 are mounted side by side on a mounting plate 3, and the output end of the robotic arm is connected to the mounting plate 3. By driving the mounting plate 3 through the robotic arm, the two graphitization box furnace cover plate gripping mechanisms 1 can be moved synchronously above the cover plate 2, reducing the use of a power source.

[0038] The cover plate 2 comprises two plates 21, each with a stepped protrusion 211 on one side. The two protrusions 211 are joined together with a gap. The cover plate 2 needs to withstand high temperatures during graphitization; this design divides the cover plate 2 into two parts to prevent cracking due to thermal stress. Each plate 21 has two connecting holes 212. When the cover plate 2 is hooked, two hooks 141 hook the two plates 21 through the two connecting holes 212 respectively, ensuring even force distribution on the two plates 21 and preventing breakage at the connection point.

[0039] In this embodiment, both connecting holes 212 are elongated and have a large area, which makes it easy for the hook 141 to be inserted and reduces the difficulty of taking the cover plate 2 out.

[0040] A tension sensor 31 is installed between the frame 11 and the mounting plate 3. During the process of the robotic arm pulling upward, the tension sensor 31 detects the tension. If it exceeds the predetermined value, the cover plate 2 may be stuck in the box. In this case, the removal of the plate is abandoned and the hook 141 is removed from the connection hole 212. If it does not exceed the predetermined value, the plate removal process continues.

[0041] The working principle of the device is as follows: After the graphitization reaction in the box furnace is completed, the entire device is moved above the cover plate 2 by a robotic arm. The floating frame 131 can drive the hook 141 to move along the first guide rail 136 and the second guide rail 138 in the X and Y directions, so that the hook 141 can extend into the connection hole 212. The piston rod of the gripper cylinder 148 extends, passing the entire hook 141 through the connection hole 212 on the cover plate 2. Then the piston rod of the gripper cylinder 148 retracts, so that the first arm 145 abuts against the lower surface of the cover plate 2. At this time, the robotic arm can try to pull upward. The tension sensor 31 detects the tension. If it exceeds the predetermined value, the removal of this plate is abandoned. The gripper cylinder 148 drives the hook 141 to be removed from the connection hole 212. If the predetermined value is exceeded, the following process continues: the leveling cylinder 123 drives each leveling rod 122 to descend synchronously, so that the lower end of each leveling rod 122 abuts against the four sides of the two plates 21. The piston rod of the reset cylinder 130 extends, driving the abutting block 115 to move towards the V-shaped notch 114 until the apex of the abutting block 115 abuts against the bottom of the V-shaped notch 114. At this time, the floating frame 131 returns to the center position, and the two plates 21 are located directly below the two frames 11 respectively. The robotic arm drives the entire device to move towards the cover plate placement point. After reaching the cover plate placement point, the leveling cylinder 123 drives the leveling rod 122 to retract upward, and the gripper cylinder 148 drives the hook 141 to be removed from the connecting hole 212. This completes the entire process of picking up and placing the cover plate 2.

[0042] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.
