[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a glue erasing device for using a small amount of glue on a motor rotor of the present invention comprises a cotton material belt supply mechanism 2, a glue dripping mechanism 3, a glue erasing mechanism 4, a cotton material belt recovery mechanism 5, and a base 1. The cotton material belt supply mechanism 2, the glue dripping mechanism 3, the glue erasing mechanism 4, and the cotton material belt recovery mechanism 5 are arranged on the base 1 in sequence. The cotton material belt passes through the cotton material belt supply mechanism 2, the glue dripping mechanism 3, the glue erasing mechanism 4, and the cotton material belt recovery mechanism 5 in sequence. The glue dripping mechanism 3 drips glue on the cotton material belt passing through. The glue erasing mechanism 4 grabs the rotor and contacts the cotton material belt and rotates to perform glue erasing. The cotton material belt recovery mechanism 5 pulls the cotton material belt and collects the cotton material belt in a centralized manner.

[0022] A cotton tape supply station, a glue dripping station, a glue wiping station, and a cotton tape recovery station are sequentially arranged on the base 1. Each station can adopt a long strip assembly line structure, which can also save space. Figure 1 The annular assembly line structure is provided, and a cotton tape supply mechanism 2, a glue dripping mechanism 3, a glue wiping mechanism 4, and a cotton tape recovery mechanism 5 are sequentially arranged at the corresponding workstations to meet the automation operation of the entire rotor wiping process.

[0023] like Figure 2As shown, the cotton tape supply mechanism 2 includes a feed bracket 21, a supply tray 22 with uncoated cotton tape, a first feed drive wheel 23, a second feed drive wheel 25, and an elastic wheel 24. The feed bracket 21 is installed on the base 1, and the supply tray 22, the first feed drive wheel 23, the second feed drive wheel 25, and the elastic wheel 24 are all connected to the feed bracket 21. The cotton tape passes through the supply tray 22 and passes through the first feed drive wheel 23, the elastic wheel 24, and the second feed drive wheel 25 in sequence before being fed into the glue dripping mechanism 3.

[0024] The supply tray 22 is filled with cotton tape raw materials. The cotton tape is straightened by the first feeding transmission wheel 23, the tension wheel 24, and the second feeding transmission wheel 25 and then enters the subsequent mechanism to complete the supply of the cotton tape.

[0025] The cotton tape supply mechanism 2 also includes a tray motor 26, which is mounted on the feed bracket 21, and the output shaft of the tray motor 26 is connected to the supply tray 22. The tray motor 26 drives the supply tray 22 to rotate, so that the cotton tape raw material buffer wound on the supply tray 22 is released, and the subsequent stretching speed of the cotton tape recovery mechanism 5 is matched to realize the continuous transmission of the cotton tape between multiple mechanisms, so that the entire device can complete the automatic operation of dripping glue and rotor wiping glue during the transmission process of the cotton tape.

[0026] The cotton material belt supply mechanism 2 also includes an elastic slider 27, which is slidably connected to the feeding bracket 21, and the elastic wheel 24 is connected to the elastic slider 27. The elastic slider 27 adjusts the distance between the elastic wheel 24 and the first feeding drive wheel 23 and the second feeding drive wheel 25. The first feeding drive wheel 23 and the second feeding drive wheel 25 are located above the elastic wheel 24. After the cotton material belt extends from the supply material tray 22, it successively bypasses the first feeding drive wheel 23, the elastic wheel 24, and the second feeding drive wheel 25 to form a triangular position. When the cotton material belt is pulled too tight, the distance between the elastic wheel 24 and the first feeding drive wheel 23 and the second feeding drive wheel 25 can be reduced to loosen the tightness of the cotton material belt; when the cotton material belt is pulled too loose, the distance between the elastic wheel 24 and the first feeding drive wheel 23 and the second feeding drive wheel 25 can be increased to tighten the tightness of the cotton material belt.

[0027] like Figure 3 As shown, the glue dripping mechanism 3 includes a glue dripping tube 33 filled with glue, a glue dripping transmission wheel 32, and a glue dripping bracket 31. The glue dripping bracket 31 is installed on the base 1. The glue dripping tube 33 and multiple glue dripping transmission wheels 32 are connected to the glue dripping bracket 31. Multiple glue dripping transmission wheels are connected to the cotton material belt of the cotton material belt supply mechanism 2. The glue dripping tube 33 is located above the cotton material belt passing through. A glue dripping needle nozzle 34 is provided at the bottom of the glue dripping tube 33, and the glue dripping needle nozzle 34 is connected to the surface of the cotton material belt.

[0028] The glue dripping drive wheel 32 receives the cotton tape from the second feeding drive wheel 25 of the cotton tape supply mechanism 2, straightens the cotton tape and makes its wide side face upward, passes under the glue dripping tube 33, and the glue dripping needle nozzle 34 outlet of the glue dripping tube 33 can contact the cotton tape, or can be slightly higher than the cotton tape but not contact the cotton tape. The glue is slowly dripped on the cotton tape by utilizing the viscosity of the glue, and the anaerobic glue is absorbed and infiltrated by utilizing the strong adsorption property of the cotton tape, and then transmitted to the glue wiping mechanism 4 to stick the glue to the neck of the rotor.

[0029] like Figure 4 As shown, the glue erasing mechanism 4 includes a grabbing assembly, a glue erasing transmission wheel 44, a lifting cylinder 42, a lifting slide rail 43, and a glue erasing bracket 41. The glue erasing bracket 41 is connected to the base 1, the lifting cylinder 42, the lifting slide rail 43, and multiple glue erasing transmission wheels 44 are connected to the glue erasing bracket 41, the grabbing assembly is slidably connected to the lifting slide rail 43, the output shaft of the lifting cylinder 42 is connected to the grabbing assembly, and multiple glue erasing transmission wheels are connected to the cotton material belt of the glue dripping mechanism 3, and the grabbing assembly drives the rotor to contact the passing glue cotton material belt.

[0030] The glue-wiping transmission wheel 44 receives the cotton material belt after glue absorption from the glue-driving transmission wheel 32 of the glue-driving mechanism 3, and straightens the cotton material belt under the grabbing assembly. The grabbing assembly grabs a rotor from the upstream rotor feeding device, and the grabbing assembly is driven by the lifting cylinder 42 through the lifting slide rail 43 to descend to the cotton material belt between the glue-wiping transmission wheels 44, so that the neck of the rotor contacts the cotton material belt and sticks to the glue.

[0031] The grab assembly includes a rotary motor 47, a grab head 46 matching the rotor, and a grab bracket 45. The grab bracket 45 is connected to the lifting slide rail 43, the rotary motor 47 is connected to the grab bracket 45, and the grab head 46 is connected to the output shaft of the rotary motor 47. The grab head 46 can adopt a cylindrical structure matching the rotor, and the middle part of the rotor is inserted into the grab head 46 and clamped and fixed, or it can be fixed by magnetic attraction; after clamping the rotor, the grab bracket 45 drives the grab head 46 to drop to the cotton material belt between the two glue-wiping transmission wheels 44. Since the cotton material belt has absorbed and infiltrated anaerobic glue, when the neck of the rotor contacts the cotton material belt, the glue will stick to one side of the neck of the rotor. At this time, the rotary motor 47 drives the grab head 46 to rotate, thereby driving the neck of the rotor to rotate one circle on the cotton material belt. After the neck of the rotor is evenly coated with glue, the lifting cylinder 42 drives the rotor to separate from the cotton material belt through the grab bracket 45, and the rotor is docked with the next transfer process.

[0032] like Figure 5As shown, the cotton material belt recovery mechanism 5 includes a recovery material tray 51, a driving gear 52, a driven gear 53, a recovery motor 54, and a synchronous belt 55. The recovery motor 54 is installed on the base 1, the driving gear 52 is provided with a gear drive shaft 57, and the recovery material tray 51 is provided with a material tray drive shaft 56. The recovery motor 54 is connected to the gear drive shaft 57, and the gear drive shaft 57 and the material tray drive shaft 56 are connected through a synchronous belt 55. The driving gear 52 and the driven gear 53 are connected and pull the passing cotton material belt.

[0033] The driving gear 52 and the driven gear 53 clamp the cotton material belt from the middle, and as the recovery motor 54 drives the driving gear 52 to rotate, the cotton material belt is pulled to transfer the waste cotton material belt to the recovery material tray 51. Since the gear drive shaft 57 and the material tray drive shaft 56 are connected by the synchronous belt 55, the recovery material tray 51 also maintains the same rotation speed as the driving gear 52. While the driving gear 52 transmits the cotton material belt, the recovery material tray 51 winds the cotton material belt layer by layer to collect the waste materials in a unified manner. After the recovery material tray 51 is filled with waste cotton material belt, it is only necessary to remove the recovery material tray 51 and unload the waste materials, reinstall the empty recovery material tray 51 on the material tray drive shaft 56, and wind the newly generated cotton material belt on it, and then the waste material recovery operation can be continued.

[0034] like Figure 1 As shown, the glue erasing device for applying a small amount of glue to the motor rotor includes a platform base 6, a base motor 11, and a base slider 12. The platform base 6 is provided with a base slide rail 61, the base motor 11 is mounted on the platform base 6, the output shaft of the base motor 11 is connected to the base 1, the base slider 12 is slidably connected to the base slide rail 61, and the base 1 is mounted on the base slider 12. The base motor 11 drives the base 1 to move on the platform base 6 through the base slider 12, so that the position adjustment of the base 1 on the platform base 6 can be achieved, thereby adjusting the position relationship between the whole machine and the upstream and downstream process equipment, and facilitating docking with other whole machines and equipment. For example, the position relationship with the rotor feeding equipment can be adjusted, so that the glue erasing mechanism 4 can grab the unprocessed rotor and dock it to the transfer equipment of the next process after applying glue.

[0035] The working principle of the glue erasing device for micro-amount of glue on motor rotors is as follows:

[0036] A full supply tray 22 is placed on the tray motor 26, and after one end of the cotton material belt is passed through, it passes through the first feeding transmission wheel, the tension wheel 24, the second feeding transmission wheel, the glue dripping transmission wheel 32, and the glue wiping transmission wheel 44 in sequence, and then is clamped by the driving gear 52 and the driven gear 53, and the end is wound on the recovery tray 51, the full glue dripping tube 33 is installed, and the glue dripping needle nozzle 34 is aligned with the cotton material belt on the glue dripping station. The recovery motor 54 is started, and the driving gear 52 and the driven gear 53 begin to pull the cotton material belt to move toward the recovery tray 51. The cotton material belt is recovered and wound by the self-rotation of the recovery tray 51. At the same time, the tray motor 26 is started to rotate the supply tray 22 and slowly release the cotton material belt. The rotation speed of the tray motor 26 can match the recovery motor 54. While the cotton material belt is being conveyed, the glue dripping needle 34 of the glue dripping tube 33 slowly drips anaerobic glue on the cotton material belt, and the glue is absorbed and infiltrated by the adsorption of the cotton material belt. The cotton material belt after glue absorption is continuously conveyed to the glue wiping mechanism 4. At this time, the gripping head 46 clamps a rotor, and the lifting motor drives the foot wiping bracket to descend, and moves the neck of the rotor to contact the cotton material belt. At this time, the rotating motor 47 drives the gripping head 46 to rotate, so that the rotor is glued with glue all around, and then the rotor is transferred to the next process for assembly with the bearing and the stator, and then a rotor without glue is re-grabbed for operation. After the cotton tape in the supply tray 22 is used up, stop the tray motor 26 and the recovery motor 54, remove the recovery tray 51 and clean up the waste of the recovered cotton tape, then reload the full supply tray 22 and the empty recovery tray 51, and repeat the above steps.

[0037] The glue wiping device for the motor rotor with trace glue completes the automatic transmission of the cotton material belt from supply to recycling, and continuously drips glue to the cotton material belt through the glue dripping tube 33, ensuring the automatic supply of glue. At the same time, it cooperates with the grabbing mechanism to automatically grab the rotor and drive the rotor to rotate, completing the full range of gluing action on the rotor. The entire operation process only requires manual intervention in the replacement of the supply tray 22, the recovery tray 51, and the glue dripping tube 33. The other major production processes are completed in an automated manner, which greatly reduces the workload of manual labor and solves the problems of time-consuming and labor-intensive manual operations, low production efficiency, and inability to guarantee the quality of glue dispensing.

[0038] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
