Description

Technical Field

[0001] This utility model relates to the technical field of toner cartridge assembly equipment, and more particularly to torsion spring assembly equipment for toner cartridge protective covers. 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. During assembly, a torsion spring needs to be installed on the gear end of the toner cartridge protective cover. The torsion spring is relatively small, and its two pins need to be pressed into two positioning grooves on the gear end. Because the space at the gear end is narrow, manually installing the torsion spring is difficult, time-consuming, and labor-intensive, resulting in low efficiency. Utility Model Content

Two torsion spring-mounted lateral movement sliders 324 are slidably connected to two torsion spring-mounted lateral movement slide rails 323, respectively. The tops of both torsion spring-mounted lateral movement sliders 324 are connected to the bottom ends of the torsion spring-mounted lateral movement base 325. The torsion spring-mounted lateral movement threaded shaft 322 is threadedly connected to the bottom center of the torsion spring-mounted lateral movement base 325. The second lateral movement base 336 of the torsion spring mounting structure 33 is mounted on top of the torsion spring-mounted lateral movement base 325.

[0036] The torsion spring mounting lateral movement motor 321 provides power for the left and right movement of the torsion spring mounting structure 33. The torsion spring mounting lateral movement threaded shaft 322 drives the torsion spring mounting lateral movement base 325 to move left and right, serving a transmission function. The cooperation of the torsion spring mounting lateral movement slide rail 323 and the torsion spring mounting lateral movement slider 324 guides the torsion spring mounting lateral movement base 325. The torsion spring mounting lateral movement base 325 is used to mount the torsion spring mounting structure 33. The torsion spring mounting fixed base 326 is used to mount the torsion spring mounting lateral movement threaded shaft 322, the torsion spring mounting lateral movement slide rail 323, and the torsion spring mounting lateral movement motor 321.

The rotary compression spring motor 331 is connected to the right end of the rotating shaft 3321, and the left end of the rotating shaft 3321 is connected to the central shaft 3322 and the stop shaft 3323, respectively. The centerline of the central shaft 3322 overlaps with the centerline of the rotating shaft of the rotary compression spring motor 331. The stop shaft 3323 is located on one side of the central shaft 3322. The right end of the torsion spring foot stop 335 is mounted on the top of the second transverse moving base 336 and is located at the left front end of the rotary compression spring motor 331. The left end of the torsion spring foot stop 335 is located on one side of the left end of the central shaft 3322. The push spring cylinder 333 is mounted on the top of the second transverse moving base 336 and is located in front of the rotary compression spring motor 331. The push spring block 334 is connected to the push spring cylinder 333. The middle part of the central shaft 3322 slidably passes through the push spring block 334, and the push spring block 334 is clearance-fitted with the central shaft 3322. The left end of the central shaft 3322 can be fitted with the torsion spring 7.

[0038] The rotary spring motor 331 provides power to the stop shaft 3323 to push the first pin 71 of the torsion spring 7. The spring component 332, by rotating itself, pushes the first pin 71 of the torsion spring 7, bringing the two pins (i.e., the first pin 71 and the second pin 72) closer together. The spring-pushing cylinder 333 provides power to transfer the torsion spring 7 from the spring component 332 to the drum protective cover 6. The spring-pushing block 334 is used to transfer the torsion spring 7 from the spring component 332 to the drum protective cover 6. The torsion spring foot stop block 335 limits the second pin 72 of the torsion spring 7. The second transverse moving base 336 is used to mount the rotary spring motor 331, the torsion spring foot stop block 335, and the spring-pushing cylinder 333.

[0040] like Figure 9 As shown, the material handling lateral movement structure 22 includes a material handling lateral movement motor 221, a first synchronous belt 222, a lateral threaded shaft 223, two lateral slide rails 224, two lateral sliders 225, two threaded blocks 226, and a fixed base 227. The fixed base 227 is mounted on the top of the material handling frame 21. The material handling lateral movement motor 221 is mounted on the bottom of the fixed base 227, and the two ends of the lateral threaded shaft 223 are rotatably mounted on the top of the fixed base 227. The two lateral slide rails 224 are mounted on the top of the fixed base 227 and located on both sides of the lateral threaded shaft 223, with the lateral threaded shaft 223 and the lateral slide rails 224 parallel to each other. Synchronous pulleys are mounted on both the material handling lateral movement motor 221 and the lateral threaded shaft 223, and the two synchronous pulleys are connected by the first synchronous belt 222. The two threaded blocks 226 are threadedly connected to the lateral threaded shaft 223. The two lateral sliders 225 are slidably connected to the two lateral slide rails 224 respectively. The top of the transverse slider 225 and the top of the threaded block 226 are both connected to the bottom of the first transverse moving base 237 of the longitudinal moving structure 23 for picking up materials.

[0041] The material-picking lateral movement motor 221, which is a clamping structure 25, moves left and right in the second direction. A first synchronous belt 222 transmits power from the material-picking lateral movement motor 221 to the lateral threaded shaft 223. The lateral threaded shaft 223 drives the threaded block 226 to move left and right in the second direction. The lateral slide rail 224 and the lateral slider 225 guide the threaded block 226. The fixed base 227 is used to mount the material-picking lateral movement motor 221, the lateral threaded shaft 223, and the lateral slide rail 224.

[0042] like Figure 10As shown, the longitudinal moving structure 23 for material handling includes a longitudinal moving motor 231, a longitudinal threaded rod 233, two longitudinal slide rails 234, two longitudinal sliders 235, two longitudinal moving bases 236, and a first transverse moving base 237. The first transverse moving base 237 is mounted on the transverse threaded shaft 223 and the transverse sliders 225 of the transverse moving structure 22 for material handling. The longitudinal threaded rod 233 is rotatably mounted on the top of the first transverse moving base 237.

The middle portions of the two longitudinal moving bases 236 are threadedly connected to the longitudinal threaded rod 233. The two longitudinal slide rails 234 are mounted on the first transverse moving base 237, located on the left and right sides of the longitudinal threaded rod 233, respectively. The two longitudinal sliders 235 are slidably connected to the two longitudinal slide rails 234, respectively.

The flip base 245 of the torsion spring flipping structure 24 is mounted on the top of the longitudinal moving base 236.

[0043] The longitudinal moving motor 231 moves back and forth in the first direction for the clamping structure 25. The longitudinal threaded rod 233 cooperates with the longitudinal moving base 236, allowing the longitudinal moving motor 231 to drive the longitudinal moving base 236 to move back and forth. The cooperation of the longitudinal slide rail 234 and the longitudinal slider 235 guides the longitudinal moving base 236. The longitudinal moving base 236 supports the torsion spring flipping structure 24. The first transverse moving base 237 is used to mount the longitudinal moving motor 231, the longitudinal slide rail 234, and the longitudinal threaded rod 233.

The end of the drive shaft is flipped and connected to the clamping cylinder 251 of the clamping structure 25. The gripper 252 is connected to the clamping cylinder 251.

[0045] The rotary motor 241 provides power for the rotation of the gripper 252, ensuring that the torsion spring 7 held by the gripper 252 is positioned in accordance with the receiving requirements of the torsion spring mounting structure 33 of the torsion spring mounting mechanism 3. The second synchronous belt 242 acts as a transmission belt, transmitting the power of the rotary motor 241 to the tilting synchronous pulley 244. The shaft bracket 243 is used to mount the drive shaft. The tilting synchronous pulley 244 also acts as a transmission belt. The tilting base 245 is used to mount the rotary motor 241 and the shaft bracket 243. The gripping cylinder 251 provides power for the opening and closing of the gripper 252. The gripper 252 is used to hold the torsion spring 7.

[0046] like Figure 12 As shown, the pressing mechanism 4 includes a pressing bracket 41, a first pressing cylinder 42, a first pressing block 43, a second pressing cylinder 44, a second pressing block 45, and a pressing fixture 5. The pressing fixture 5 is located on the left side of the torsion spring mounting lateral movement structure 32. The toner cartridge protective cover 6 is placed on the pressing fixture 5. The pressing bracket 41 is located behind the pressing fixture 5. The first pressing cylinder 42 is installed at the left end of the pressing bracket 41, and the second pressing cylinder 44 is installed at the right end of the pressing bracket 41. The first pressing block 43 is connected to the first pressing cylinder 42, and the second pressing cylinder 44 is connected to the second pressing block 45. Both the first pressing block 43 and the second pressing block 45 are located above the pressing fixture 5.

[0047] Operating process description of the torsion spring assembly equipment for toner cartridge protective covers:

[0048] Step 1: The torsion spring picking mechanism 2 picks up materials from the feeder 1: The feeder 1 moves the torsion spring 7 from inside the feeder 1 to the picking end of the feeder 1 by vibration. The torsion spring 7 has two pins, namely the first pin 71 and the second pin 72. At this time, the first pin 71 and the second pin 72 of the torsion spring 7 are both facing backward. The clamping structure 25 moves to the picking end of the feeder 1 through the picking lateral movement structure 22 and the picking longitudinal movement structure 23, and clamps one torsion spring 7 from the picking end. After the torsion spring 7 is clamped, the feeder 1 moves another torsion spring 7 to the picking end of the feeder 1. When the picking lateral movement structure 22 and the picking longitudinal movement structure 23 drive the torsion spring 7 to move, the torsion spring flipping structure 24 simultaneously drives the clamping structure 25 to flip, that is, flip the torsion spring 7 180 degrees (the first pin 71 and the second pin 72 of the torsion spring 7 are both facing forward).

[0049] Step 2: The torsion spring picking mechanism 2 transfers the torsion spring 7 to the torsion spring mounting mechanism 3. Under the action of the picking lateral movement structure 22 and the picking longitudinal movement structure 23, the clamping structure 25 moves to the left of the central shaft 3322. At this time, the spring coil of the torsion spring 7 is facing the central shaft 3322. Under the action of the picking lateral movement structure 22, the torsion spring 7 is fitted onto the central shaft 3322. The clamping cylinder 251 of the clamping structure 25 drives the gripper 252 to release the torsion spring 7. At this time, the second pin 72 of the torsion spring 7 is located behind the torsion spring foot stop 335, and the first pin 71 of the torsion spring 7 is in front of the stop shaft 3323. Then, the picking lateral movement structure 22 drives the clamping structure 25 to move to the left, the picking longitudinal movement structure 23 drives the clamping structure 25 to move backward, and at the same time, the torsion spring flipping structure 24 drives the clamping structure 25 to flip and reset.

[0050] Step 3: The torsion spring mounting mechanism 3 compresses the two pins of the torsion spring 7: The rotating spring motor 331 of the torsion spring mounting structure 33 rotates, driving the rotating shaft 3321 to rotate. That is, the torsion spring foot stop 335 pushes the first pin 71 of the torsion spring 7 to move forward. Because the second pin 72 is restricted by the torsion spring foot stop 335, the first pin 71 and the second pin 72 move closer to each other.

[0051] Step 4, as follows Figure 12 and 13 As shown, the torsion spring mounting mechanism 3 mounts the torsion spring 7 onto the toner cartridge protective cover 6; the adhesive pressing mechanism 4 fixes the toner cartridge protective cover 6 onto the adhesive clamp 5. The torsion spring mounting lateral movement structure 32 drives the torsion spring mounting structure 33 to move from right to left. When the torsion spring mounting structure 33 approaches the toner cartridge protective cover 6, it stops, and the push spring cylinder 333 drives the push spring block 334 to move from right to left, pushing the torsion spring 7 from the right end of the central shaft 3322 to the left end, and finally fitting it onto the plastic shaft of the toner cartridge protective cover 6. At the same time, the first pin 71 of the torsion spring 7 disengages from the restriction of the stop shaft 3323, and the second pin 72 disengages from the restriction of the torsion spring foot stop block 335. The first pin 71 and the second pin 72 are both reset under the action of the elastic force of the torsion spring 7 and snap into the slot of the toner cartridge protective cover 6, completing the assembly of the torsion spring 7 and the toner cartridge protective cover 6.

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.
