Description

Technical Field

[0001] This utility model relates to the technical field of automatic assembly of toner cartridges, and more particularly to an assembly device for the cover and spring. Background Technology

[0002] A toner cartridge, also known as a photosensitive drum, is generally composed of a base material made of aluminum and a photosensitive material coated on the base material. The end cap is a component of the toner cartridge. The spring is relatively small and needs to be installed onto the end cap. The operator manually installs the spring onto the end cap, which is difficult and inefficient. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and to provide an assembly device for the cover and the spring.

[0004] The objective of this utility model is achieved through the following technical solution: The assembly device for the cover and spring includes an automatic feeding mechanism, an end cover fixing mechanism, and a spring mounting mechanism.

The spring rotation mounting structure includes a gripper rotation assembly and a clamping assembly. The clamping assembly includes a spring clamping cylinder, a rod fixing seat, a spring rod, a first spring gripper, and a second spring gripper. The horizontal angle rotation structure is connected to the gripper rotation assembly through the horizontal movement structure. The gripper rotation assembly is connected to the spring clamping cylinder. One end of the spring rod is mounted on the outside of the spring clamping cylinder through the rod fixing seat. The first spring gripper and the second spring gripper are both mounted on the movable end of the spring clamping cylinder. The other end of the spring rod is located between the first spring gripper and the second spring gripper. The automatic feeding mechanism is connected to the end cover fixing mechanism through the spring rod, the first spring gripper, and the second spring gripper. This device can automatically feed springs, clamp springs, and install springs onto end caps without manual intervention, reducing the difficulty of operation for workers and improving work efficiency.

[0005] A better alternative is that the gripper rotation assembly includes a spring rotation motor, a second motor mounting bracket, a connecting rod, and a spring rotation base. The spring rotation motor is mounted on the horizontal moving structure via the second motor mounting bracket, which is connected to the spring rotation base via the connecting rod. The spring rotation motor is also connected to the spring gripping cylinder via the spring rotation base. This gripper rotation assembly allows for easier gripping of the spring and easier attachment of the spring to the spring post of the end cap.

[0006] A better alternative is the automatic feeding mechanism, which includes an automatic feeder and a spring positioning structure. The discharge end of the automatic feeder is connected to the spring positioning structure, which is matched with the spring insert, the first spring gripper, and the second spring gripper. This mechanism enables the feeding of springs one by one and allows the spring mounting mechanism to grasp them precisely.

[0007] A better alternative is a spring positioning structure comprising a spring positioning bracket, a spring clamping cylinder, a spring pushing block, and a spring seat. The spring clamping cylinder and the spring seat are mounted on the spring positioning bracket. The movable end of the spring clamping cylinder is connected to the spring pushing block. The spring seat is located below the spring pushing block. One side of the spring seat is connected to the automatic feeder, and the other side of the spring seat is respectively matched with the spring insert rod, the first spring gripper, and the second spring gripper. This structure can automatically fix the spring, facilitating the gripping of the spring rotation mounting structure.

[0008] A better alternative is that the end cap fixing mechanism includes an end cap fixing bracket, an end cap clamping cylinder, an end cap pressing block, and an end cap seat. The end cap clamping cylinder is mounted on the end cap fixing bracket. The end cap pressing block is connected to the movable end of the end cap clamping cylinder. The end cap pressing block corresponds to the end cap seat, and the end cap seat is respectively matched with the spring insert rod, the first spring clamp, and the second spring clamp. This mechanism can fix the end cap and facilitates the installation of the spring through a rotating spring mounting structure.

[0009] A better alternative is that the horizontal moving structure includes a horizontal moving motor, a screw, a threaded block, a horizontal fixed base, a slide rail, a slider, and a sliding limit block. The horizontal moving motor is mounted on the horizontal angle rotation structure via the horizontal fixed base. The horizontal moving motor is connected to the screw, and the screw is threadedly connected to the threaded block. The slide rail is mounted on both sides of the screw, and the slider is slidably connected to the slide rail. Both the threaded block and the slider are connected to the bottom of the spring rotation mounting structure.

[0010] A better alternative is that the horizontal angle rotation structure includes a horizontal angle rotation motor, a coupling, a first motor fixing bracket, and a horizontal angle adjustment base. The horizontal angle rotation motor and the horizontal angle adjustment base are respectively connected to both ends of the first motor fixing bracket. The horizontal angle rotation motor is connected to the horizontal angle adjustment base through the coupling, and the horizontal angle adjustment base is connected to the horizontal moving structure.

[0011] A better option is that the horizontal angle adjustment base includes a drive shaft, a bearing, a rotating shaft base, and a rotating base. The drive shaft is mounted on the rotating shaft base via the bearing. The rotating shaft base is mounted on the first motor fixing bracket. The lower end of the drive shaft is connected to the coupling, and the upper end of the drive shaft is connected to the rotating base. The rotating base is connected to the horizontal moving structure.

Detailed Implementation

[0027] The utility model objective of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation of this utility model is not limited to the following embodiments.

[0028] like Figure 1As shown, the assembly device for the cover and spring includes an automatic feeding mechanism 1, an end cap fixing mechanism 2, and a spring mounting mechanism 3. The automatic feeding mechanism 1 includes an automatic feeder 11 and a spring positioning structure 12. The automatic feeder 11 is located on the right side of the spring positioning structure 12, the spring mounting mechanism 3 is located on the left side of the spring positioning structure 12, and the end cap fixing mechanism 2 is located in front of the spring positioning structure 12. The discharge end of the automatic feeder 11 is connected to the spring positioning structure 12. The spring mounting mechanism 3 clamps the spring 4 from the spring positioning structure 12, rotates to the end cap fixing mechanism 2, and mounts the spring 4 onto the end cap 5 of the end cap fixing mechanism 2.

[0029] Automatic feeding mechanism 1 is used for automatically feeding and positioning spring 4. Automatic feeding machine 11, which can be purchased from the market, uses vibration generated by a vibratory feeder to move spring 4 along a specific track, thus achieving automatic feeding. Spring positioning structure 12 is used to push spring 4, facilitating spring mounting mechanism 3 to grasp spring 4. End cap fixing mechanism 2 is used to fix end cap 5, facilitating spring mounting mechanism 3 to position and install spring 4 on end cap 5. Spring mounting mechanism 3 is used to grasp spring 4 on spring positioning structure 12 and install spring 4 on end cap 5.

[0030] like Figure 2 and 3 As shown, the spring positioning structure 12 includes a spring positioning bracket 121, a spring clamping cylinder 122, a spring pushing block 123, a spring seat 124, and a spring positioning sensor 125. The spring clamping cylinder 122 is mounted on the upper end of the spring positioning bracket 121, with its extension rod pointing downwards and connected to the top of the spring pushing block 123. The spring seat 124 is mounted in the middle of the spring positioning bracket 121 and located directly below the spring pushing block 123. The spring seat 124 has a through spring positioning groove 1241 and a pressing block alignment groove 1242 perpendicularly intersecting the spring positioning groove 1241. One end of the spring positioning groove 1241 of the spring seat 124 is connected to the discharge end of the automatic feeder 11. The spring positioning sensor 125 is installed in the middle of the spring positioning bracket 121, and the spring positioning sensor 125 corresponds to the other end of the spring positioning groove 1241 of the spring seat 124.

[0031] The spring positioning bracket 121 is used to fix and install the spring positioning bracket 121, the spring seat 124, and the spring positioning sensor 125. The spring pressing cylinder 122 provides power to the spring pressing block 123 to press the spring 4. The spring pressing block 123 is used to press the spring 4 into the spring seat 124. The spring seat 124 is used to place the spring 4 and position it. The spring positioning sensor 125 is used to sense whether the spring 4 is in the spring seat 124 and to provide feedback to the spring mounting mechanism 3.

[0032] like Figure 4 As shown, the end cap fixing mechanism 2 includes an end cap fixing bracket 21, an end cap clamping cylinder 22, an end cap pressing block 23, and an end cap seat 24. The end cap clamping cylinder 22 is mounted on the upper end of the end cap fixing bracket 21. The telescopic rod of the end cap clamping cylinder 22 points downwards and is connected to the top of the end cap pressing block 23. The end cap seat 24 is located below the end cap pressing block 23, and the end cap pressing block 23 corresponds to the end cap seat 24. The end cap seat 24 is provided with an end cap positioning groove 241. The end cap fixing bracket 21 is used to fix the end cap clamping cylinder 22. The end cap clamping cylinder 22 provides power for the end cap pressing block 23 to push the end cap 5. The end cap pressing block 23 is used to clamp the end cap 5, aligning the spring 4 on the spring mounting mechanism 3 with the end cap 5. The end cap seat 24 is used to position the end cap 5.

[0033] like Figure 5 As shown, the spring mounting mechanism 3 includes a horizontal angle rotation structure 31, a horizontal movement structure 32, and a spring rotation mounting structure 33. The rotating end of the horizontal angle rotation structure 31 is connected to the bottom of the horizontal movement structure 32. The horizontal movement end of the horizontal movement structure 32 is connected to the bottom of the spring rotation mounting structure 33. The horizontal angle rotation structure 31 is used to adjust the rotation angle of the spring rotation mounting structure 33, allowing the spring rotation mounting structure 33 to mate with the end cap fixing mechanism 2 and the spring positioning structure 12 respectively. The horizontal angle rotation structure 31 is used for inserting the spring rotation mounting structure 33 into the spring 4 or for mounting the spring 4 onto the spring post of the end cap 5 using the spring rotation mounting structure 33.

[0034] like Figure 6 As shown, the horizontal angle rotation structure 31 includes a horizontal angle rotation motor 311, a coupling 312, a first motor fixing bracket 313, and a horizontal angle adjustment base 314. The horizontal angle rotation motor 311 is connected to the bottom of the first motor fixing bracket 313. The bottom of the horizontal angle adjustment base 314 is connected to the top of the first motor fixing bracket 313. The rotating shaft of the horizontal angle rotation motor 311 passes through the first motor fixing bracket 313 and is connected to the coupling 312, which is connected to the horizontal angle adjustment base 314. The top of the horizontal angle adjustment base 314 is connected to the bottom of the horizontal fixed base 323 of the horizontal moving structure 32.

[0035] like Figure 7As shown, the horizontal angle adjustment base 314 includes a drive shaft 3141, four bearings 3142, a rotating base 3143, a rotating base 3144, and two base positioning sensors. The four bearings 3142 are sleeved on the outer wall of the drive shaft 3141 and are installed inside the rotating base 3143. The lower end of the drive shaft 3141 is connected to a coupling 312, and the upper end of the drive shaft 3141 is connected to the center of the bottom of the rotating base 3144. Two base positioning sensors are provided on the outer periphery of the rotating base 3143, which can sense whether the rotating base 3144 has reached a specified angle. The rotating base 3144 is connected to the bottom of the horizontal fixed base 323 of the horizontal moving structure 32.

[0036] A horizontal angle rotation motor 311 provides power for the rotation of the horizontal angle adjustment base 314. A coupling 312 serves as a transmission mechanism. A first motor mounting bracket 313 is used to securely mount the horizontal angle rotation motor 311 and the horizontal angle adjustment base 314. The horizontal angle adjustment base 314 serves as a transmission mechanism and allows for confirmation of its rotation angle. A drive shaft 3141 serves as a transmission mechanism. A bearing 3142 allows the drive shaft 3141 to rotate relative to the rotating base 3143. A rotating base 3144 is used to mount and fix the horizontal fixed base 323. A base positioning sensor is used to sense when the rotating base 3144 has rotated to a designated position.

[0037] like Figure 8 As shown, the horizontal moving structure 32 includes a horizontal moving motor 321, a screw 322, a threaded block 326, a horizontal fixed base 323, two slide rails 324, two sliders 325, and two sliding limit blocks 327. The horizontal moving motor 321 is mounted on the side of the horizontal fixed base 323, which is mounted on top of the horizontal angle adjusting base 314 of the horizontal angle rotation structure 31. The screw 322 is rotatably mounted on the horizontal fixed base 323 via a rod bracket. The shaft of the horizontal moving motor 321 is connected to the screw 322, and the screw 322 is threadedly connected to the threaded block 326. The two slide rails 324 are respectively mounted on the horizontal fixed base 323 and located on both sides of the screw 322. The two sliders 325 are slidably connected to the two slide rails 324. The tops of the threaded block 326 and the tops of the sliders 325 are both connected to the bottom of the second motor fixing bracket 332 of the spring rotation mounting structure 33.

[0038] The horizontal moving motor 321 provides power for the rotation of the screw 322. Both the screw 322 and the threaded block 326 serve a transmission function, enabling the second motor mounting bracket 332 to move horizontally. The horizontal fixed base 323 is used to fix the horizontal moving motor 321, the screw 322, and the two slide rails 324. The cooperation between the slide rails 324 and the slider 325 guides the second motor mounting bracket 332. The sliding limit block 327 limits the sliding range of the slider 325.

[0039] like Figure 9 and 10 As shown, the spring-rotating mounting structure 33 includes a gripper rotating assembly and a clamping assembly. The gripper rotating assembly includes a spring-rotating motor 331, a second motor fixing bracket 332, four connecting rods 333, and a spring-rotating base 334. The clamping assembly includes a spring-clamping cylinder 335, a rod fixing seat 336, a spring rod 337, a first spring gripper 338, and a second spring gripper 339. The second motor fixing bracket 332 is mounted on top of the threaded block 326 and the two sliders 325 of the horizontal moving structure 32. The spring-rotating motor 331 is connected to one end of the second motor fixing bracket 332. The spring-rotating base 334 is connected to the other end of the second motor fixing bracket 332 via the four connecting rods 333. The rotating end of the spring-rotating base 334 is connected to the spring-clamping cylinder 335. One end of the spring insert 337 is mounted on the housing of the spring clamping cylinder 335 via the insert fixing seat 336. The first spring jaw 338 and the second spring jaw 339 are both mounted on the movable end of the spring clamping cylinder 335. The other end of the spring insert 337 is located between the first spring jaw 338 and the second spring jaw 339.

[0040] The gripper rotation assembly drives the clamping assembly to rotate, making it easier for the spring insert 337 to be inserted into the spring 4 or for the spring 4 to be more easily fitted onto the spring post of the end cap 5. The spring rotation motor 331 provides power for the rotation of the spring insert 337. The second motor mounting bracket 332 is used to mount and fix the spring rotation motor 331 and the connecting rod 333. The connecting rod 333 is used to fix the spring rotation base 334 to the second motor mounting bracket 332. The structure of the spring rotation base 334 is similar to that of the horizontal angle adjustment base 314, allowing the spring insert 337 to rotate relative to the spring 4. The clamping assembly is used to clamp the spring 4 or to mount the spring 4 onto the spring post of the end cap 5. The spring clamping cylinder 335 drives the first spring gripper 338 and the second spring gripper 339 to open and close. The insert rod fixing seat 336 is used to fix the spring insert 337 to the spring clamping cylinder 335. The spring insert 337 is used to fit onto the spring 4. The first spring jaw 338 and the second spring jaw 339 are used to clamp the spring 4.

[0041] Description of the working process of the cover and spring assembly device: The automatic feeder 11 transfers the spring 4 from the inside to the spring seat 124 of the spring positioning structure 12 by vibration. The spring push block 123 presses the spring 4 onto the spring seat 124 to prevent the spring 4 from moving further. The horizontal angle rotation structure 31 drives the spring rotation mounting structure 33 to the spring positioning structure 12, and the spring insert 337 is on the same axial line as the spring 4. The horizontal movement structure 32 pushes the spring positioning structure 12 forward, and part of the spring insert 337 is inserted into one end of the spring 4. The spring clamping cylinder 335 drives the first spring clamp 338 and the second spring clamp 339 to clamp the outside of the spring 4. The spring pressing cylinder 122 of the spring positioning structure 12 drives the spring push block 123 to move upward, and then the horizontal movement structure 32 drives the spring rotation mounting structure 33 to clamp the spring 4 and retract together. The horizontal angle rotation structure 31 drives the spring rotation mounting structure 33 to turn to the end cover fixing mechanism 2. The spring 4 stops rotating when it is aligned with the spring post of the end cap 5 of the end cap fixing mechanism 2. The horizontal moving structure 32 drives the spring rotation mounting structure 33 to move closer to the end cap 5 of the end cap fixing mechanism 2. At the same time, the spring rotation motor 331 drives the spring insertion rod 337 to rotate, allowing the spring 4 to move closer to the end cap 5 while rotating, making it easier for the spring 4 to fit into the spring post of the end cap 5. After the spring 4 is fitted into the spring post of the end cap 5, the spring clamping cylinder 335 drives the first spring clamp 338 and the second spring clamp 339 to release the spring 4. Then, the horizontal moving structure 32 drives the spring insertion rod 337 to retract, separating the spring insertion rod 337 from the spring 4, thus completing the connection between the spring 4 and the end cap 5.

[0042] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
