[0025] The present utility model provides the following description with reference to the accompanying drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to facilitate understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0026] In the description of the present utility model, orientation descriptions are involved. For example, the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0027] It should be understood that when an element (for example, the first element) is "connected" to another element (for example, the second element), the element can be directly connected to the other element, or there can be an intermediate element (for example, the third element) between the element and the other element.

[0028] Before specifically describing the present utility model, it is necessary to introduce the structure of the existing motor. As Figure 1 shown, it is a small motor in the prior art. Its cover plate 11 and the bottom shell form the outer shell of the whole motor. The cover plate 11 is provided with two lugs 12, and positioning holes 13 are arranged on the lugs 12 to facilitate the positioning of the cover plate 11 and facilitate the assembly of the cover plate 11.

[0029] An embodiment of the present utility model provides an automatic feeding device for a motor cover plate. As Figure 2 shown, it includes a cover plate vibrating disk assembly 210, a blanking chute 220, a flexible vibration assembly 230, a cover plate position and orientation detection assembly 240, and a cover plate grasping and rotating assembly 250. The blanking chute 220 is inclined relative to the horizontal direction. Therefore, the blanking chute 220 has an upper end with a higher height and a lower end with a lower height. The upper end of the blanking chute 220 is docked with the cover plate vibrating disk assembly 210 to receive the cover plates output by the cover plate vibrating disk assembly 210, and the lower end of the blanking chute 220 is docked with the flexible vibration assembly 230 to convey the cover plates to the flexible vibration assembly 230.

[0030] The cover plate vibrating disk assembly 210 is used to output the cover plates with the front side facing up, so that the cover plates fed are all with the front side facing up, which is convenient for subsequently assembling the cover plates onto the bottom case of the motor and prevents the cover plates from being installed backwards. After the cover plate vibrating disk assembly 210 outputs the cover plates, the cover plates slide down along the blanking chute 220 to the flexible vibration assembly 230. In this embodiment, the blanking chute 220 is used to convey the cover plates, taking advantage of the gravity of the cover plates themselves. Without applying a driving force to the cover plates, the cover plates slide down naturally onto the flexible vibration assembly 230. During this process, it is difficult for the cover plates to flip, ensuring that the cover plates conveyed to the flexible vibration assembly 230 still remain with the front side facing up.

[0031] After the cover plates with the front side facing up are conveyed to the flexible vibration assembly 230, the flexible vibration assembly 230 is used to vibrate the cover plates to disperse them, preventing the cover plates that slide onto the flexible vibration assembly 230 from stacking together, so that the cover plates are all dispersed from each other, facilitating the cover plate position and orientation detection component 240 to detect each cover plate and also facilitating the cover plate grasping and rotating component 250 to accurately grasp each cover plate. Among them, the intensity of the flexible vibration assembly 230 vibrating the cover plates can be adjusted so that the cover plates can be dispersed, and at the same time, it will not cause the cover plates with the front side facing up to flip.

[0032] After the flexible vibration assembly 230 disperses the cover plates, the flexible vibration assembly 230 will stop working to avoid the vibration affecting subsequent detection. The cover plate position and orientation detection component 240 is arranged above the flexible vibration assembly 230 and is used to detect the positions of the cover plates dispersed on the flexible vibration assembly 230, facilitating the cover plate grasping and rotating component 250 to grasp the cover plates according to this position. The cover plate position and orientation detection component 240 is also used to detect the orientation angles of the cover plates, so that the cover plate grasping and rotating component 250 can rotate the grasped cover plates according to this orientation angle. The cover plate grasping and rotating component 250 is used to grasp the cover plates on the flexible vibration assembly 230 according to the detected positions of the cover plates and move the cover plates away, conveying them to the designated position to complete the feeding, and the cover plate grasping and rotating component 250 is also used to rotate the grasped cover plates to the designated angle according to the detected orientation angles. In this way, the cover plate grasping and rotating component 250 can convey the cover plates with the front side facing up and with a unified orientation angle for feeding, which is convenient for subsequent assembly of the cover plates. The entire above process is automatically implemented by mechanical equipment, realizing the automated operation of cover plate feeding and can improve production efficiency.

[0033] It should be noted that the cover vibrating disk assembly 210, the flexible vibration assembly 230, the cover position and orientation detection assembly 240, and the cover grasping and rotating assembly 250 can all be connected to the control module. The control module issues corresponding control instructions to the cover vibrating disk assembly 210, the flexible vibration assembly 230, the cover position and orientation detection assembly 240, and the cover grasping and rotating assembly 250 according to the set control program, so that the cover vibrating disk assembly 210, the flexible vibration assembly 230, the cover position and orientation detection assembly 240, and the cover grasping and rotating assembly 250 can work in coordination with each other to complete the feeding of the cover.

[0034] In some embodiments, as Figure 3 and Figure 4 shown, the cover grasping and rotating assembly includes a cover three-dimensional moving mechanism 251, a cover grasping base 252, a cover rotating mechanism 253, a cover grasping mechanism 254, and an angle detection mechanism 255. The cover grasping base 252 is connected to the cover three-dimensional moving mechanism 251. The cover three-dimensional moving mechanism 251 is used to drive the cover grasping base 252 to move in the horizontal, vertical, and longitudinal directions. Among them, the horizontal and longitudinal directions can both be parallel to the horizontal direction, and the horizontal and longitudinal directions are perpendicular to each other. Thus, the three-dimensional movement of the cover grasping base 252 can be realized. Correspondingly, the devices connected to the cover grasping base 252 move three-dimensionally with the cover grasping base 252.

[0035] The cover rotating mechanism 253 is arranged on the cover grasping base 252. The cover grasping mechanism 254 is used to grasp the cover, and the cover grasping mechanism 254 is connected to the cover rotating mechanism 253. The cover rotating mechanism 253 is used to drive the cover grasping mechanism 254 to rotate, and correspondingly, the orientation angle of the cover grasped by the cover grasping mechanism 254 can be changed. The angle detection mechanism 255 is used to detect whether the orientation angle of the cover grasped by the cover grasping mechanism 254 is the same as the specified angle. When the orientation angle of the cover grasped by the cover grasping mechanism 254 is the same as the specified angle, the cover rotating mechanism 253 stops rotating, and the orientation angle of the cover grasped by the cover grasping mechanism 254 can be the same as the specified angle.

[0036] The working process of the cover plate grasping and rotating assembly in this embodiment is as follows: After the cover plate position and orientation detection component detects the position and orientation angle of the cover plates scattered on the flexible vibration component, it sends the detected position and orientation angle of the cover plates to the control module. The control module sends corresponding instructions to the cover plate three-dimensional movement mechanism 251 according to the detected position of the cover plates. The cover plate three-dimensional movement mechanism 251 drives the cover plate grasping mechanism 254 to approach the cover plates. The cover plate grasping mechanism 254 then grabs the cover plates. The cover plate three-dimensional movement mechanism 251 then drives the cover plate grasping mechanism 254 away from the flexible vibration component to transfer the cover plates to the designated position. When the cover plates are transferred to the designated position, the cover plate grasping mechanism 254 releases the cover plates to realize the feeding of the cover plates; during the process that the cover plate three-dimensional movement mechanism 251 drives the cover plate grasping mechanism 254 away from the flexible vibration component, the cover plate rotating mechanism 253 drives the cover plates grabbed by the cover plate grasping mechanism 254 to rotate. When the orientation angle of the cover plates grabbed by the cover plate grasping mechanism 254 is the same as the designated angle, the cover plate rotating mechanism 253 stops rotating, and the orientation angle of the cover plates grabbed by the cover plate grasping mechanism 254 can be the same as the designated angle, so that the cover plates with a unified orientation angle can be output outward.

[0037] Further, the cover plate grasping mechanism 254 includes two groups of cover plate positioning columns 256. During the process of grasping the cover plates, the cover plate three-dimensional movement mechanism 251 moves the cover plate grasping base 252 downward in the vertical direction, and the two groups of cover plate positioning columns 256 can be respectively inserted into the positioning holes of the two lugs of the cover plate. On the one hand, this can more accurately position the cover plates, so as to accurately grab the cover plates. On the other hand, since the lugs are located at specific positions of the cover plate, after positioning the cover plate through the cover plate positioning columns 256, the orientation angle of the cover plate is consistent with the orientation angle of the cover plate grasping mechanism 254. Subsequently, only by adjusting the orientation angle of the cover plate grasping mechanism 254 can the cover plate be rotated to the designated angle to simplify the process and rotate the cover plate to the designated angle faster.

[0038] It should be noted that since the cover plate position and orientation detection component detects the orientation angle of the cover plates, the cover plate rotating mechanism 253 can rotate the cover plate grasping mechanism 254 according to this orientation angle so that the two groups of cover plate positioning columns 256 can be aligned with the positioning holes on the two lugs.

[0039] In this embodiment, the cover plate positioning columns 256 can be elastic columns, which can elastically move in the vertical direction. This can avoid the rigid contact between the cover plate positioning columns 256 and the lugs of the cover plate and avoid damaging the cover plate.

[0040] Further, the cover plate rotation mechanism 253 includes a central rotation shaft. The cover plate rotation mechanism 253 is used to drive the rotation of its central rotation shaft. The cover plate gripping mechanism 254 is connected to the central rotation shaft, and accordingly, the cover plate gripping mechanism 254 can be driven to rotate. The angle detection mechanism 255 includes a shading disk 2551 and a groove type photoelectric sensor 2552. The shading disk 2551 is coaxially connected to the central rotation shaft, so that it can rotate with the central rotation shaft, and the rotation angle of the shading disk 2551 is the same as the rotation angle of the cover plate gripping mechanism 254. The shading disk 2551 passes through the groove of the groove type photoelectric sensor 2552 to block the optical signal, so that the photoelectric sensor 2552 is not triggered. At the same time, a light-transmitting slit is provided on the shading disk 2551, and the angle of the light-transmitting slit on the shading disk 2551 corresponds to a specified angle. When the light of the groove type photoelectric sensor 2552 passes through the light-transmitting slit and causes the groove type photoelectric sensor 2552 to be triggered, it indicates that the orientation angle of the cover plate grasped by the cover plate gripping mechanism 254 has rotated to the same as the specified angle, and the cover plate rotation mechanism 253 can stop rotating, so that the orientation angle of the cover plate remains the same as the specified angle.

[0041] In this embodiment, the cover plate rotation mechanism 253 may include a motor. The central rotation shaft is the output shaft of the motor. The motor output shaft can penetrate the housing of the motor to form a double-headed motor. The shading disk 2551 can be fixed to the upper end of the output shaft, and the cover plate gripping mechanism 254 can be fixed to the lower end of the output shaft.

[0042] In some embodiments, the cover plate gripping mechanism 254 further includes a cover plate magnetic adsorption head, and the cover plate magnetic adsorption head can generate a magnetic adsorption force to grasp the cover plate. Alternatively, the cover plate gripping mechanism 254 further includes a cover plate negative pressure adsorption head. The cover plate negative pressure adsorption head is provided with a negative pressure hole or a negative pressure suction cup. The cover plate negative pressure adsorption head is also connected to a vacuum pumping device to generate a negative pressure suction force on the negative pressure hole or the negative pressure suction cup, and use the negative pressure suction force to adsorb the cover plate. Alternatively, the cover plate gripping mechanism 254 further includes a cover plate clamping claw, and the cover plate is clamped by the approaching of the cover plate clamping claws to each other, and the cover plate is released by the separation of the cover plate clamping claws from each other.

[0043] In some embodiments, as Figure 2 shown, the cover plate vibrating disk assembly 210 includes a cover plate vibrating disk. The cover plate vibrating disk is used to screen out the cover plates with the front side facing up and convey the cover plates with the front side facing up to the blanking chute 220. The cover plate vibrating disk is internally provided with a screening mechanism. The screening mechanism will make the cover plates with the reverse side facing up fall back into the cover plate vibrating disk again, so as to only output the cover plates with the front side facing up. Since the screening mechanism already belongs to the prior art, its structure and principle will not be described in detail.

[0044] In some embodiments, as Figure 2As shown, the blanking chute 220 includes a blanking slide plate and two blanking side plates. The blanking slide plate is inclined relative to the horizontal direction, and the two blanking side plates are respectively fixed on both sides of the blanking slide plate, so that the cross-sectional shape of the blanking chute 220 can be in a "U" shape. The two blanking side plates play a blocking role on both sides of the cover plate to prevent the cover plate from sliding off both sides of the blanking slide plate, ensuring that the cover plate can finally slide onto the flexible vibration assembly 230.

[0045] In some embodiments, as Figure 2 shown, the flexible vibration assembly 230 includes a flexible vibrating disk, and the vibration generated by the flexible vibrating disk is used to disperse the cover plates.

[0046] In some embodiments, as Figure 2 and Figure 3 shown, the cover plate position and orientation detection component 240 includes a vision detection device. The vision detection device takes pictures of the cover plates on the flexible vibration assembly 230, and uses an image recognition algorithm to calculate the position of the cover plates on the flexible vibration assembly 230 and the orientation angle of the cover plates.

[0047] Furthermore, the vision detection device includes a camera 241. The lens of the camera 241 faces downward to take pictures of the cover plates on the flexible vibration assembly 230 below. The vision detection device may also include a fill light 242 to provide supplementary light for the camera 241 to ensure the shooting effect. This makes the entire cover plate position and orientation detection component 240 have advantages such as good stability, strong strain capacity, and high efficiency.

[0048] In some embodiments, as Figure 2 shown, the automatic loading device for the motor cover plate of this embodiment further includes a cover plate storage bin 260 and a cover plate feeding component 270. The cover plate storage bin 260 is used to place cover plates, and the cover plate feeding component 270 is used to convey the cover plates in the cover plate storage bin 260 to the cover plate vibrating disk. Whenever the cover plate vibrating disk works for a period of time, the number of cover plates in the cover plate vibrating disk will decrease. The cover plate feeding component 270 can add cover plates to the cover plate vibrating disk to ensure sufficient material supply, so that the entire automatic loading device for the motor cover plate can work for a long time.

[0049] In this embodiment, the cover plate feeding component 270 may include a circulating conveyor belt and a blanking track. A baffle is provided on the conveyor belt. One end of the conveyor belt extends into the cover plate storage bin 260, and the other end is docked with the blanking track. The material will stay on the baffle, and the conveyor belt will then convey the material to the blanking track, and the material will slide down along the blanking track into the cover plate vibrating disk.

[0050] In some embodiments, a detection sensor for detecting the remaining amount of the cover plates in the cover plate vibrating bowl may be provided in the cover plate vibrating bowl. When the detection sensor detects that the remaining amount of the cover plates is lower than the set value, the cover plate feeding assembly 270 starts to work to automatically replenish the cover plates in the cover plate vibrating bowl, ensuring continuous supply of the cover plates. The number of cover plates replenished by the cover plate feeding assembly 270 each time can be within a relatively stable range, and it is not advisable to add too many cover plates, reducing the risk of the cover plates being scratched due to multiple vibrations in the cover plate vibrating bowl and improving the product quality.

[0051] In some embodiments, as Figure 2 shown, the blanking chute 220 is provided with a baffle mechanism for opening or blocking the blanking chute 220. The cover plate position and orientation detection assembly 240 is also used to detect the number of cover plates on the flexible vibrating assembly 230. When the number of cover plates is less than the preset number, the baffle mechanism is used to open the blanking chute 220 to replenish the cover plates on the flexible vibrating assembly 230 in a timely manner.

[0052] Furthermore, a cover plate counter may be provided at the output end of the cover plate vibrating bowl to count the number of cover plates entering the blanking chute 220; in the initial state, the baffle mechanism blocks the blanking chute 220, so that the cover plates entering the blanking chute 220 stay in the blanking chute 220 and do not directly fall onto the flexible vibrating assembly 230. When the cover plate counter detects that the number of cover plates entering the blanking chute 220 reaches the set value, the cover plate vibrating bowl stops operating, making the number of cover plates entering the blanking chute 220 relatively stable; when the cover plate position and orientation detection assembly 240 detects that the number of cover plates on the flexible vibrating assembly 230 is less than the preset number, the baffle mechanism opens the blanking chute 220 again. Thus, a relatively stable number of cover plates can be replenished to the flexible vibrating assembly 230 each time, ensuring both material supply and preventing the cover plates from accumulating on the flexible vibrating assembly 230 and causing the cover plates to be unable to be dispersed.

[0053] In this embodiment, the baffle mechanism may include a baffle and a baffle driver connected to the baffle. The baffle driver is used to drive the baffle to move in the vertical direction. When the baffle drops, it can abut against the blanking chute to block the blanking chute and prevent the cover plates from falling. When the baffle rises, the blanking chute can be opened, and the cover plates can normally enter the flexible vibrating assembly 230 along the blanking chute.

[0054] In some embodiments, as Figure 2 shown, the cover plate position and orientation detection assembly 240 is also used to detect the front and back sides of the cover plates on the flexible vibrating assembly 230. When it detects that the back side of the cover plate is facing up, the cover plate grasping and rotating assembly 250 takes away the cover plate with the back side facing up and puts it into a dedicated collection box. Since it cannot be guaranteed that 100% of the cover plates output by the cover plate vibrating bowl are facing up, this function of the cover plate position and orientation detection assembly 240 can reduce the situation of incorrect installation of the cover plates and improve the yield rate of the products.

Therefore, those skilled in the art should clearly understand that the descriptions of the various embodiments of the present utility model provided above are only for the purpose of illustration and not for limiting the present utility model as defined by the appended claims and their equivalents.
