Description

Technical Field

[0001] The utility model relates to the technical field of grasping devices, and specifically, to a grasping device for magnetic sleeve processing. Background Art

[0002] In the fields of modern technology and industry, as a key magnetic component or protection device, the magnetic sleeve plays an indispensable role. The magnetic sleeve is an important part in a laser printer, and it and the toner cartridge both belong to printing consumables. The magnetic sleeve is usually made of materials with high magnetic permeability and low magnetic resistance characteristics, such as ferrite, rare earth permanent magnetic materials, etc. These materials can effectively guide, concentrate or shield the magnetic field to meet specific technical requirements. In the production, inspection, packaging and logistics and other links of printing consumables, it is often necessary to accurately grasp, move and place the printing consumables, which greatly shortens the time required for manual operation, thus significantly improving the overall efficiency of the production line.

[0003] There are some drawbacks in the existing devices during use. For example: in the production, inspection, packaging and logistics and other links of printing consumables, the existing grasping device only grasps the magnetic sleeve through the outer circle, and the contact area between the claw and the magnetic sleeve is limited. This will cause the magnetic sleeve to shift or fall off due to uneven force during movement or operation, thus affecting the grasping stability. In a working environment with large vibrations, the grasping method with limited contact points is more vulnerable to interference, increasing the risk of the magnetic sleeve falling off. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a grasping device for magnetic sleeve processing, so as to solve the problem that in the production, inspection, packaging and logistics and other links of printing consumables, the existing grasping device only grasps the printing consumable (magnetic sleeve) through the outer circle.

[0005] The utility model provides the following technical solution: A gripping device for magnetic sleeve processing, including a main body housing. An activity cavity is provided inside the main body housing. A first motor is fixedly connected to the upper end face of the main body housing. The output end of the first motor is fixedly connected to a first rotating shaft. The end of the first rotating shaft away from the first motor penetrates the upper end face of the main body housing and is rotatably connected to the upper end face of the main body housing. A first rotating disk is arranged in the activity cavity, and the first rotating disk is fixedly sleeved on the outer side of the end of the first rotating shaft away from the first motor. Three activity slots are annularly arranged on the lower end face of the main body housing. The three activity slots communicate with the activity cavity. A first activity block is slidably connected in each of the three activity slots. A spiral limiting slot is annularly arranged on the lower end face of the first rotating disk. A spiral limiting block adapted to the size of the spiral limiting slot is fixedly connected to the top end of each of the three first activity blocks. The three first activity blocks are slidably connected to the first rotating disk through the spiral limiting blocks. A first claw is fixedly connected to the bottom end of each of the three first activity blocks. A connecting frame is fixedly connected to the lower end face of the main body housing. An auxiliary claw assembly for assisting the three first claws is arranged on the connecting frame.

[0006] In the above solution, the cooperation of the spiral limiting slot and the spiral limiting block realizes the synchronous and precise movement of the three first activity blocks and the first claws. As the first rotating disk rotates, the special shape of the spiral limiting slot guides the spiral limiting block to slide along a predetermined trajectory, thereby driving the first activity blocks to move closer to the center and realizing the stable clamping of the magnetic sleeve.

[0007] As a preference of the above technical solution, the auxiliary claw assembly includes a triangular mounting plate fixedly connected to the bottom end of the connecting frame. A second motor is fixedly connected to the inner bottom wall of the connecting frame. The output end of the second motor is fixedly connected to a second rotating shaft. The end of the second rotating shaft away from the second motor penetrates the bottom end of the connecting frame and the triangular mounting plate and is rotatably connected to the bottom end of the connecting frame and the triangular mounting plate. The auxiliary claw assembly further includes three moving slots annularly arranged at the three corners of the lower end face of the triangular mounting plate. A moving block is slidably connected to the inner side of each of the three moving slots. A second activity block is fixedly connected to the bottom end of each of the three moving blocks. The three second activity blocks are slidably connected to the triangular mounting plate through the corresponding moving blocks. A second rotating disk is fixedly sleeved on the outer side of the end of the second rotating shaft away from the second motor. One side of the lower end face of each of the three second activity blocks close to the second rotating disk is rotatably connected to a connecting rod. The end of each of the three connecting rods away from the second activity block is rotatably connected to the lower end face of the second rotating disk. A second claw is fixedly connected to the end of each of the three second activity blocks away from the second rotating disk.

[0008] In the above solution, the second motor drives the second rotating disk to rotate, and then drives the three second claws to clamp the inner hole of the magnetic sleeve from the inside. This way of clamping from both inside and outside significantly enhances the clamping stability.

[0009] Preferably, as an embodiment of the above technical solution, on the inner walls of the opposite sides of the three movable slots, moving card slots are horizontally formed. On the outer walls of the opposite sides of the three first movable blocks, at positions corresponding to the moving card slots, moving card blocks adapted to the sizes of the moving card slots are fixedly connected. The three first movable blocks are slidably connected to the corresponding movable slots through the corresponding moving card blocks.

[0010] In the above solution, the cooperation between the moving card blocks and the moving card slots enables the first movable blocks to maintain a stable trajectory and posture during movement, avoiding unstable clamping or damage caused by shaking or deviation.

[0011] Preferably, as an embodiment of the above technical solution, an annular sliding block is fixedly connected to the upper end surface of the first rotating disk. An annular sliding groove adapted to the size of the annular sliding block is annularly formed on the inner top wall of the movable cavity at a position corresponding to the annular sliding block. The first rotating disk is rotatably connected to the main body housing through the annular sliding block.

[0012] In the above solution, the cooperation between the annular sliding block and the annular sliding groove effectively reduces the shaking and deviation during the rotation of the first rotating disk, improving the stability and precision of the rotation.

[0013] Preferably, as an embodiment of the above technical solution, the three second claws are used in cooperation with the three first claws.

[0014] In the above solution, this dual clamping mechanism makes the magnetic sleeve more stable during the grasping process, not prone to sliding or falling off, thereby improving production efficiency and safety.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, the cooperation between the first claw and the second claw in the auxiliary claw assembly can not only clamp the outer circle of the magnetic sleeve but also clamp the inner hole of the magnetic sleeve when clamping the magnetic sleeve, forming a multi-point collaborative clamping mechanism. This mechanism not only increases the contact area with the magnetic sleeve but also effectively prevents the magnetic sleeve from deviating or falling off during the grasping process through the uniform force of multiple clamping points, significantly improving the stability of the clamping.

[0024] Embodiment

[0025] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the present utility model provides a technical solution: a grasping device for magnetic sleeve processing, including a main body housing 10. An activity cavity 11 is provided inside the main body housing 10. A first motor 12 is fixedly connected to the upper end face of the main body housing 10. The output end of the first motor 12 is fixedly connected to a first rotating shaft 13. The end of the first rotating shaft 13 away from the first motor 12 penetrates the upper end face of the main body housing 10 and is rotatably connected to the upper end face of the main body housing 10. A first rotating disk 14 is arranged in the activity cavity 11, and the first rotating disk 14 is fixedly sleeved on the outer side of the end of the first rotating shaft 13 away from the first motor 12. Three activity slots 15 are annularly arranged on the lower end face of the main body housing 10. The three activity slots 15 communicate with the activity cavity 11. A first activity block 16 is slidably connected in each of the three activity slots 15. A spiral limiting groove 17 is annularly arranged on the lower end face of the first rotating disk 14. The top ends of the three first activity blocks 16 are fixedly connected with spiral limiting blocks 18 adapted to the size of the spiral limiting groove 17. The three first activity blocks 16 are slidably connected to the first rotating disk 14 through the spiral limiting blocks 18. The bottom ends of the three first activity blocks 16 are fixedly connected with first clamping claws 19. A connecting frame 20 is fixedly connected to the lower end face of the main body housing 10. An auxiliary clamping claw assembly 2 for assisting the three first clamping claws 19 is arranged on the connecting frame 20. In the specific use process, the first motor 12 is driven to drive the first rotating shaft 13 to drive the first rotating disk 14 to rotate. As the first rotating disk 14 rotates, the special shape of the spiral limiting groove 17 starts to act on the spiral limiting blocks 18, driving the three first activity blocks 16 to slide towards the center along the activity slots 15. The three first activity blocks 16 respectively drive the corresponding first clamping claws 19 to gradually approach the center and close, so as to realize the clamping of the printing consumables (magnetic sleeve). After the first clamping claws 19 initially clamp the magnetic sleeve, the auxiliary clamping claw assembly 2 starts to work to enhance the overall grasping stability. When it is necessary to release the magnetic sleeve, it can be realized by reversely starting the first motor 12. At the same time, the auxiliary clamping claw assembly 2 also stops working and no longer applies a clamping force to the magnetic sleeve.

[0026] As an implementation manner in this embodiment, as Figure 1 and Figure 4As shown in the figure, the auxiliary jaw assembly 2 includes a triangular mounting plate 201 fixedly connected to the bottom end of the connecting frame 20. A second motor 202 is fixedly connected to the inner bottom wall of the connecting frame 20. The output end of the second motor 202 is fixedly connected to a second rotating shaft 203. The end of the second rotating shaft 203 away from the second motor 202 penetrates through the bottom end of the connecting frame 20 and the triangular mounting plate 201 and is rotatably connected to the bottom end of the connecting frame 20 and the triangular mounting plate 201. The auxiliary jaw assembly 2 further includes moving grooves 204 annularly arranged at three corners of the lower end surface of the triangular mounting plate 201. Three moving blocks 205 are slidably connected to the inner sides of the three moving grooves 204. The bottom ends of the three moving blocks 205 are fixedly connected to second movable blocks 206. The three second movable blocks 206 are slidably connected to the triangular mounting plate 201 through the corresponding moving blocks 205 respectively. A second rotating disk 207 is fixedly sleeved on the outer side of the end of the second rotating shaft 203 away from the second motor 202. One side of the lower end surfaces of the three second movable blocks 206 close to the second rotating disk 207 is rotatably connected to a connecting rod 208. The ends of the three connecting rods 208 away from the second movable blocks 206 are rotatably connected to the lower end surface of the second rotating disk 207. The ends of the three second movable blocks 206 away from the second rotating disk 207 are fixedly connected to second jaws 209. In the specific use process, the second motor 202 is driven to drive the second rotating shaft 203 to drive the second rotating disk 207 to rotate. The rotation of the second rotating disk 207 drives the connection points of its lower end surface and the three connecting rods 208 to start moving along a circular track. Since the other end of the connecting rod 208 is rotatably connected to the second movable block 206, the rotational movement of the connecting rod 208 will be converted into a linear movement of the second movable block 206. Driven by the connecting rods 208, the three second movable blocks 206 slide outward along the corresponding moving grooves 204 respectively. During the sliding process, the second movable block 206 drives the corresponding second jaw 209 to gradually move outward until they can clamp the inner hole of the printing consumable (magnetic sleeve).

[0027] As an implementation manner in this embodiment, as Figure 2 、 Figure 3 and Figure 5 shown, moving card slots 30 are horizontally opened on the opposite inner side walls of the three movable slots 15. At the positions corresponding to the moving card slots 30 on the opposite outer side walls of the three first movable blocks 16, moving card blocks 31 adapted to the sizes of the moving card slots 30 are fixedly connected. The three first movable blocks 16 are slidably connected to the corresponding movable slots 15 through the corresponding moving card blocks 31. In the specific use process, during the movement of the first movable block 16, the moving card block 31 plays a guiding role in the moving card slot 30 to ensure that the first movable block 16 can slide smoothly along a predetermined track.

[0028] As an implementation manner in this embodiment, as Figure 2 and Figure 3As shown in the figure, a ring-shaped slider 40 is fixedly connected to the upper end surface of the first rotating disk 14. At the position corresponding to the ring-shaped slider 40 on the inner top wall of the movable cavity 11, a ring-shaped chute 41 adapted to the size of the ring-shaped slider 40 is annularly provided. The first rotating disk 14 is rotationally connected to the main body housing 10 through the ring-shaped slider 40. In the specific use process, the cooperation between the ring-shaped slider 40 and the ring-shaped chute 41 provides stable support and guidance for the rotation of the first rotating disk 14 on the main body housing 10.

[0029] As an implementation manner in this embodiment, as Figure 1 shown in the figure, the three second claws 209 are used in cooperation with the three first claws 19. In the specific use process, through the simultaneous action of the first claws 19 and the second claws 209, the clamping force on the printing consumable (magnetic sleeve) can be significantly increased.

[0030] Working principle: The first motor 12 drives the first rotating shaft 13 to drive the first rotating disk 14 to start rotating. The cooperation between the ring-shaped slider 40 and the ring-shaped chute 41 provides stable support and guidance for the rotation of the first rotating disk 14 on the main body housing 10. As the first rotating disk 14 rotates, the special shape of the spiral limiting groove 17 thereon begins to interact with the spiral limiting block 18. This interaction drives the three first movable blocks 16 to slide towards the center along the movable groove 15. During the sliding process of the three first movable blocks 16, they respectively drive the corresponding first claws 19 to gradually approach the center and close. During the movement of the first movable block 16, the moving block 31 plays a guiding role in the moving slot 30. When the first claws 19 close to a certain extent, they will initially clamp the outer surface of the printing consumable (magnetic sleeve). After the first claws 19 initially clamp the magnetic sleeve, the second motor 202 drives the second rotating shaft 203 to drive the second rotating disk 207 to rotate. The rotation of the second rotating disk 207 is converted into the linear motion of the second movable block 206 through the connecting rod 208, so that the three second movable blocks 206 slide outwards along the corresponding moving grooves 204 respectively. During the sliding process, the second movable blocks 206 drive the corresponding second claws 209 to gradually move outwards until they can clamp the inner hole of the printing consumable (magnetic sleeve). The simultaneous action of the first claws 19 and the second claws 209 significantly increases the clamping force on the printing consumable (magnetic sleeve).
