[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] like Figures 1 to 5 As shown, some embodiments provide a gear detection system for a clothes drying rack, comprising: a frame 1; a loading portion 2, the loading portion 2 being fixed to the frame 1 and being suitable for carrying a workpiece; the loading portion 2 comprising: a horizontal moving pair and a clamping claw, the horizontal moving pair being fixed to the frame 1, the clamping claw being fixed to the movable end of the horizontal moving pair, the horizontal moving pair being suitable for driving the clamping claw to move horizontally, the clamping claw being suitable for clamping a workpiece and moving it horizontally so as to sleeve the workpiece onto the outer wall of the positioning shaft 33. The workpiece described in the present invention is a gear. The gear described in the present invention is a driving gear used in an electric clothes drying rack, the motor drives the gear to rotate, and the gear synchronously drives the winding wheel in the electric clothes drying rack to rotate forward and reverse.

[0055] The detection portion 3 is fixed to the frame 1 and is suitable for detecting whether the workpiece is qualified. The transmission portion 4 is fixed to one side of the detection portion 3 and is suitable for driving the workpiece to rotate circumferentially within the detection portion 3. When the transmission portion 4 drives the workpiece to rotate circumferentially, the movable end of the detection portion 3 is suitable for driving the workpiece to move back and forth. When the outer wall of the workpiece is disengaged from the movable end of the transmission portion 4, the transmission portion 4 cannot drive the workpiece to rotate synchronously, and the workpiece is judged to be unqualified. Through the cooperation of the detection portion 3 and the driven gear disc 43, it is possible to detect whether the thickness of the rack on the outer wall of the workpiece is qualified. During the rotation of the workpiece, it is also possible to detect whether the length of the rack on the outer wall of the workpiece is too long, thereby improving work efficiency.

[0056] Reference Attachment Figure 2The detection part 3 includes: a positioning ring 31, which is horizontally fixed on the frame 1, and the workpiece is suitable for being placed in the positioning ring 31; the inner diameter of the positioning ring 31 is larger than the diameter of the workpiece, and after the workpiece is sleeved on the outer wall of the positioning shaft 33, when the workpiece rotates circumferentially in the positioning ring 31, the rack on the outer wall of the workpiece will not contact the inner wall of the positioning ring 31. A support plate 32, which is fixed in the positioning ring 31; the support plate 32 has a certain elasticity, that is, when the lifting assembly 34 moves downward to abut against the support plate 32, the lifting assembly 34 is suitable for squeezing the support plate 32 downward to deform it; a positioning shaft 33, which is rotatably set in the positioning ring 31, and the workpiece is suitable for being sleeved on the outer wall of the positioning shaft 33; the axis of the positioning shaft 33 coincides with the center of the circle of the positioning ring 31. The lifting assembly 34 is sleeved on the outer wall of the positioning shaft 33 . The lifting assembly 34 is linked with the positioning shaft 33 and is suitable for driving the workpiece to move reciprocally up and down.

[0057] Reference Attachment Figure 3 and Figure 4The outer wall of the positioning shaft 33 is provided with a closed-loop groove 330 along its circumferential direction. One section of the closed-loop groove 330 spirals upward along the outer wall of the positioning shaft 33, while the other section spirals downward along the outer wall of the positioning shaft 33. The lifting assembly 34 includes a lifting ring 341, which is sleeved on the outer wall of the positioning shaft 33 and is suitable for abutting against the bottom wall of the workpiece; and a linkage block 343 fixed to the inner wall of the lifting ring 341, which is slidably disposed within the closed-loop groove 330. When the positioning shaft 33 rotates circumferentially, it is suitable for driving the lifting ring 341 to reciprocate up and down along the outer wall of the positioning shaft 33. When the linkage block 343 moves in the closed-loop groove 330, it is suitable for driving the lifting ring 341 to move back and forth vertically up and down along the outer wall of the positioning shaft 33; a fixed groove is provided in the axial direction on the outer wall of the positioning shaft 33, and a fixed block adapted to the fixed groove is fixed on the inner wall of the workpiece, and the fixed block is suitable for moving vertically up and down in the fixed groove. When the driven gear disk 43 drives the workpiece to rotate, the workpiece is suitable for driving the positioning shaft 33 to rotate synchronously; when the positioning shaft 33 rotates axially, it is suitable for driving the lifting ring 341 to move back and forth vertically up and down along the outer wall of the positioning shaft 33; and the up and down reciprocating movement of the lifting ring 341 is suitable for driving the workpiece to move back and forth synchronously up and down. The lifting ring 341 drives the workpiece to move up and down reciprocatingly, with a stroke equal to the thickness of the workpiece. When the lifting ring 341 reaches its highest point, the lower surface of the rack on the workpiece's outer wall contacts the driven gear disc 43. When the lifting ring 341 reaches its lowest point, the upper surface of the rack on the workpiece's outer wall contacts the driven gear disc 43. When the rack on the workpiece's outer wall is thin, the lifting ring 341 drives the workpiece to move vertically up and down, and the rack on the workpiece's outer wall disengages from the driven gear disc 43. At this point, the driven gear disc 43 cannot drive the workpiece to continue to rotate circumferentially. A damper is provided at the bottom of the positioning shaft 33. When the external force driving the workpiece to rotate disappears, the damper is suitable for overcoming the inertia of the workpiece. That is, after the driven gear disc 43 disengages from the rack on the workpiece's outer wall, the workpiece will not continue to rotate.

[0058] Reference Attachment Figure 4 In order to apply grease to the rack on the outer wall of the workpiece, an oil storage cylinder 35 is fixed to the lower end of the support plate 32. The oil storage cylinder 35 is hollow inside and is suitable for storing grease. The oil storage cylinder 35 is arranged directly below the positioning shaft 33.

[0059] Preferably, the lifting assembly 34 further includes: a connecting post 342, which is vertically fixed to the lower end of the lifting ring 341 and is adapted to pass through the support plate 32; the connecting post 342 is parallel to the positioning shaft 33; and a piston plate 344 fixed to the lower end of the connecting post 342, the piston plate 344 being slidably adapted to the oil storage cylinder 35 and adapted to move up and down within the oil storage cylinder 35. When the piston plate 344 moves vertically up and down within the oil storage cylinder 35, it is adapted to push the grease in the oil storage cylinder 35 to flow toward the sponge strip 36.

[0060] Reference Attachment Figure 4 A sponge strip 36 is fixed circumferentially on the inner wall of the positioning ring 31. The sponge strip 36 is connected to the oil storage cylinder 35, and the rack on the outer wall of the workpiece is suitable for squeezing the sponge strip 36 to deform. The support disk 32 is provided with a plurality of flow channels along the radial direction, and the flow channels are suitable for connecting the sponge strip 36 and the oil storage cylinder 35. When the piston disk 344 moves vertically upward in the oil storage cylinder 35, the piston disk 344 is suitable for pushing the grease in the oil storage cylinder 35 so that the grease flows along the flow channel to the sponge strip 36. The sponge strip 36 is in an arc shape, and the inner diameter of the sponge strip 36 is smaller than the outer diameter of the workpiece. No sponge strip 36 is provided at the position of the inner wall of the positioning ring 31 corresponding to the notch.

[0061] To facilitate detection of excessive rack length on the workpiece's outer wall, the positioning ring 31 includes a notch within which slides a detection plate 37. This arc-shaped detection plate 37 is adapted to abut against the workpiece's outer rack. When the workpiece rotates circumferentially about the positioning axis 33, the rack on the workpiece's outer wall abuts against the inner wall of the detection plate 37. If the rack length on the workpiece's outer wall is excessive, the rack pushes the detection plate 37 outward.

[0062] To facilitate the recovery of excess grease, a conical block is fixed to the lower end of the lifting ring 341. The conical block is suitable for squeezing the middle of the support disc 32 downward. A reflux hole is provided on the support disc 32 corresponding to the oil reservoir 35. When the conical block squeezes the support disc 32 downward, excess grease on the support disc 32 is suitable for flowing into the oil reservoir 35 through the reflux hole. When the piston disc 344 moves vertically upward within the oil reservoir 35, the grease in the oil reservoir 35 is suitable for flowing outward through the flow channel to the sponge strip 36. An elastic sheet is provided on the bottom wall of the support disc 32 corresponding to the reflux hole. The elastic sheet is suitable for preventing the grease in the oil reservoir 35 from being sprayed outward through the reflux hole onto the support disc 32.

[0063] Reference Attachment Figure 2 and Figure 4The transmission part 4 includes: a driving motor, which is fixed on the frame 1, and a driving gear disc is sleeved on the end of the rotating shaft of the driving motor; a positioning plate 41, which is vertically fixed on the frame 1 and is arranged on the outside of the positioning ring 31; a linkage shaft 42, which is liftably arranged on the positioning plate 41; a driven gear disc 43, which is sleeved on the outer wall of the linkage shaft 42, the driven gear disc 43 is engaged with the driving gear disc, and the driven gear disc 43 is suitable for driving the workpiece to rotate circumferentially.

[0064] Some embodiments provide a method for detecting a gear detection system for a clothes drying rack. A specific method for detecting a gear detection system for a clothes drying rack is as follows:

[0065] The movable end of the loading part 2 clamps the workpiece, and after the workpiece is horizontally moved to the detection part 3, the movable end of the clamping part is suitable for fixing the workpiece on the outer wall of the positioning shaft 33;

[0066] When the workpiece slides vertically downward along the outer wall of the positioning shaft 33, the rack on the outer wall of the workpiece is adapted to engage with the driven gear disc 43;

[0067] The driving motor drives the driven gear disc 43 to rotate, and the driven gear disc 43 is suitable for driving the workpiece to rotate synchronously; the workpiece is suitable for driving the positioning shaft 33 to rotate synchronously in the circumferential direction;

[0068] During the circumferential rotation of the positioning shaft 33 , it is suitable for driving the lifting ring 341 to slide vertically up and down along the outer wall of the positioning shaft 33 ;

[0069] The lifting ring 341 can synchronously drive the workpiece to slide vertically up and down along the outer wall of the positioning shaft 33;

[0070] When the thickness of the outer wall of the workpiece is unqualified, the rack on the outer wall of the workpiece is disengaged from the driven gear plate 43. At this time, the driven gear plate 43 cannot drive the workpiece to continue rotating. A damper is provided at the lower end of the positioning shaft 33. After the driven gear plate 43 is disengaged from the rack on the outer wall of the workpiece, the damper at the lower end of the positioning shaft 33 is suitable for overcoming the inertia of the workpiece rotation. That is, after the workpiece is disengaged from the driven gear plate 43, the workpiece will not rotate.

[0071] When the length of the rack on the outer wall of the workpiece exceeds a preset value, the rack on the outer wall of the workpiece can push the detection plate 37 so that the detection plate 37 is separated from the notch.
