[0039] The present invention provides the following description with reference to the accompanying drawings to assist in a comprehensive understanding of various embodiments of the present invention as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be considered as exemplary only. 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 invention.

[0040] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0042] An embodiment of the present invention provides an automatic assembly machine for a motor cover, such as Figure 2 and Figure 3 As shown, it includes a motor conveying device 100, a cover plate feeding device 200, a cover plate transfer device 300, a cover plate assembly device 400 and an assembly positioning device 500. The motor conveying device 100 is used to convey the motor tooling, and the motor tooling is used to place the motor product assembled with the output shaft. The use of the motor tooling to place the motor product can facilitate the circulation of the motor product. The motor conveying device 100 moves the motor tooling along the preset conveying direction. The moving path of the motor tooling includes the cover plate assembly station. The motor conveying device 100 can move the motor tooling with the motor product assembled with the output shaft to the cover plate assembly station. The cover plate assembly work is performed at the cover plate assembly station. After the cover plate assembly is completed, the motor conveying device 100 can also move the motor tooling out of the cover plate assembly station, or other devices can move the motor tooling with the motor product assembled with the output shaft to the cover plate assembly station. After the cover plate assembly is completed, other devices can also move the motor tooling out of the cover plate assembly station.

[0043] The cover plate loading device 200 is used to move the cover plate facing up and facing the same angle as the specified angle to the cover plate transfer device 300 to ensure that the cover plate can be accurately assembled on the motor product later. If the cover plate faces up or the angle of the cover plate is different from the specified angle, the output shaft cannot be aligned with the output hole, and the cover plate cannot be accurately assembled.

[0044] The cover plate transfer device 300 is used to transport the cover plates to the cover plate assembly device 400. The cover plates transported are all facing upward and facing at the same angle as the specified angle, so that the cover plate assembly device 400 can obtain these cover plates and then assemble them.

[0045] When the motor tooling is moved to the cover plate assembly station, the assembly positioning device 500 is used to position the motor tooling so that the position of the motor tooling remains stable, the motor product on the motor tooling also remains stable, and the cover plate can be accurately aligned with the motor product. At the same time, the assembly positioning device 500 is also used to clamp and fix the output shaft on the motor product so that the output shaft remains stable. The cover plate assembly device 400 then assembles the cover plate transported by the cover plate transfer device 300 onto the motor product. During the assembly process, the output hole on the cover plate is aligned with the output shaft, and the cover plate assembly device 400 then drives the cover plate close to the output shaft so that the output shaft is inserted into the output hole. Due to the positioning of the motor tooling and the clamping of the output shaft by the assembly positioning device 500, the assembly of the cover plate will not cause the output shaft to tilt or tip over, and the output shaft maintains its original assembly state. When the cover plate is in a semi-assembled state with the output shaft passing through the output hole by a preset distance, the assembly positioning device 500 is used to loosen the clamping of the output shaft so as not to affect the further assembly of the cover plate. The cover plate assembly device 400 then fully assembles the cover plate into place to complete the assembly of the cover plate.

[0046] The entire process of this embodiment is automatically implemented by mechanical equipment, which can realize the automated assembly of the cover plate, improve production efficiency, and keep the output shaft in a correct assembly state.

[0047] It should be noted that the motor conveying device 100, the cover feeding device 200, the cover transferring device 300, the cover assembling device 400 and the assembly positioning device 500 of the present embodiment can all be connected to the control module. The control module sends corresponding control instructions to the motor conveying device 100, the cover feeding device 200, the cover transferring device 300, the cover assembling device 400 and the assembly positioning device 500 according to a preset control program, so that the motor conveying device 100, the cover feeding device 200, the cover transferring device 300, the cover assembling device 400 and the assembly positioning device 500 can coordinate with each other to complete the assembly of the cover.

[0048] In some embodiments, Figure 4 and Figure 5As shown, the assembly positioning device includes a first positioning drive assembly 510, a positioning connecting frame 530, a motor tooling positioning assembly 540 and an output shaft clamping assembly 550. The motor tooling positioning assembly 540 includes two positioning fork rods 541, and the two positioning fork rods 541 and the output shaft clamping assembly 550 are both fixed on the positioning connecting frame 530, so that the two positioning fork rods 541 and the output shaft clamping assembly 550 are both linked with the positioning connecting frame 530. The first positioning drive assembly 510 is connected to the positioning connecting frame 530 and is used to drive the positioning connecting frame 530 to move along a conveying direction perpendicular to the motor tooling 20, so that the two positioning fork rods 541 and the output shaft clamping assembly 550 can be close to or away from the motor tooling 20 located at the cover assembly station.

[0049] When the motor fixture 20 moves to the cover assembly station, the first positioning drive assembly 510 is used to drive the positioning connection frame 530 to approach the motor fixture 20 so that the motor fixture 20 is inserted into the two positioning fork rods 541, thereby positioning the motor fixture 20, and limiting the movement of the motor fixture 20 along the conveying direction through the two positioning fork rods 541 to keep it stable. The output shaft clamping assembly 550 clamps and fixes the output shaft on the motor product to keep the output shaft stable.

[0050] The output shaft clamping assembly 550 may include two clamping jaws and a clamping jaw driver connected to the two clamping jaws, wherein the clamping jaw driver is used to drive the two clamping jaws toward each other to clamp the output shaft, and is also used to drive the two clamping jaws away from each other to release the clamping of the output shaft.

[0051] The two positioning fork rods 541 are arranged in parallel. In the direction in which the motor tooling 20 is inserted between the two positioning fork rods 541, the distance between the inner side surfaces of the outwardly extending ends of the two positioning fork rods 541 gradually decreases, so that the motor tooling 20 can be guided to be accurately inserted between the two positioning fork rods 541.

[0052] Furthermore, the assembly positioning device 500 also includes a second positioning drive assembly 520, which is connected to the first positioning drive assembly 510 and is used to drive the first positioning drive assembly 510 to move along the conveying direction of the motor fixture 20, and correspondingly drives the positioning connecting frame 530, the motor fixture positioning assembly 540 and the output shaft clamping assembly 550 to move along the conveying direction of the motor fixture 20. At the same time, multiple motor fixture positioning assemblies 540 and output shaft clamping assemblies 550 are provided along the conveying direction of the motor fixture 20. Thus, the assembly positioning device 500 will form a fork feeding device, which can not only position the motor fixture 20 and clamp the output shaft, but also move the motor fixture 20 along the conveying direction. This does not require the motor fixture 20 to be equipped with an additional conveying device, which can simplify the structure of the entire motor cover automatic assembly machine, so that the entire motor cover automatic assembly machine can operate simply and efficiently.

[0053] At the same time, when the second positioning drive component 520 drives the first positioning drive component 510 to move along the conveying direction of the motor tooling 20, the output shaft clamping component 550 maintains the output shaft on the motor product clamped and fixed. Therefore, when the motor tooling 20 is conveyed, the output shaft on the motor product will not be skewed or tilted, so that the output shaft maintains its original assembly state, ensuring that the cover can be accurately assembled on the motor product.

[0054] In this embodiment, the first positioning drive assembly 510 and the second positioning drive assembly 520 may include a cylinder, which is arranged perpendicular to the conveying direction of the motor fixture 20 or parallel to the conveying direction of the motor fixture 20, and the first positioning drive assembly 510 is driven to move along the conveying direction of the motor fixture 20 and the positioning connecting frame 530 is driven to move along the conveying direction perpendicular to the motor fixture 20 by the extension and contraction of the push rod of the cylinder. Of course, the first positioning drive assembly 510 and the second positioning drive assembly 520 can also be other drive assemblies such as linear rails and motor screw mechanisms.

[0055] In some embodiments, Figure 6 and Figure 7 As shown, the cover plate feeding device includes a cover plate vibration plate assembly 210, a material dropping chute 220, a flexible vibration assembly 230, a cover plate position orientation detection assembly 240, and a cover plate grabbing and rotating assembly 250. The material dropping chute 220 is inclined relative to the horizontal direction, so that the material dropping chute 220 has a higher upper end and a lower lower end. The upper end of the material dropping chute 220 is docked with the cover plate vibration plate assembly 210 to receive the cover plate output by the cover plate vibration plate assembly 210, and the lower end of the material dropping chute 220 is docked with the flexible vibration assembly 230 to transport the cover plate to the flexible vibration assembly 230.

[0056] The cover plate vibration disk assembly 210 is used to output the cover plates facing up, so that the loaded cover plates are facing up, which is convenient for the subsequent assembly of the cover plates to the bottom shell of the motor and prevents the cover plates from being installed upside down. After the cover plate vibration disk assembly 210 outputs the cover plates, the cover plates slide along the blanking chute 220 to the flexible vibration assembly 230. This embodiment uses the blanking chute 220 to transport the cover plates, and utilizes the gravity of the cover plates themselves. There is no need to apply a driving force to the cover plates. The cover plates naturally slide onto the flexible vibration assembly 230. During this process, the cover plates are difficult to flip over, ensuring that the cover plates transported to the flexible vibration assembly 230 remain facing up.

[0057] After the cover plate facing up is delivered to the flexible vibration assembly 230, the flexible vibration assembly 230 is used to vibrate the cover plate to disperse the cover plate, prevent the cover plates that slide onto the flexible vibration assembly 230 from stacking together, and disperse the cover plates from each other, so that the cover plate position orientation detection assembly 240 can detect each cover plate, and the cover plate grabbing and rotating assembly 250 can accurately grab each cover plate. The strength of the flexible vibration assembly 230 to vibrate the cover plate can be adjusted, so that the cover plates can be dispersed, and at the same time, the cover plate facing up will not be turned over.

[0058] After the flexible vibration assembly 230 disperses the cover plates, the flexible vibration assembly 230 will stop working to prevent vibration from affecting subsequent detection. The cover plate position orientation detection assembly 240 is arranged above the flexible vibration assembly 230 and is used to detect the position of the dispersed cover plates on the flexible vibration assembly 230, so that the cover plate grabbing rotating assembly 250 can grab the cover plates according to this position. The cover plate position orientation detection assembly 240 is also used to detect the orientation angle of the cover plates, so that the cover plate grabbing rotating assembly 250 can rotate the cover plates according to this orientation angle. The cover plate grabbing rotating assembly 250 is used to grab the cover plates on the flexible vibration assembly 230 according to the detected position of the cover plates, and move the cover plates to the cover plate transfer device to complete the loading, and the cover plate grabbing rotating assembly 250 is also used to rotate the grabbed cover plates to a specified angle according to the detected orientation angle, so that the cover plate grabbing rotating assembly 250 can convey the cover plates with the front side facing up and the uniform orientation angle for loading, which is convenient for the subsequent assembly of the cover plates.

[0059] It should be noted that the cover plate vibration disk assembly 210, the flexible vibration assembly 230, the cover plate position orientation detection assembly 240 and the cover plate grabbing and rotating assembly 250 can all be connected to the control module, and the control module sends corresponding control instructions to the cover plate vibration disk assembly 210, the flexible vibration assembly 230, the cover plate position orientation detection assembly 240 and the cover plate grabbing and rotating assembly 250 according to the set control program, so that the cover plate vibration disk assembly 210, the flexible vibration assembly 230, the cover plate position orientation detection assembly 240 and the cover plate grabbing and rotating assembly 250 can coordinate with each other to complete the loading of the cover.

[0060] Further, such as Figure 7 and Figure 8As shown, the cover plate grabbing and rotating assembly includes a cover plate three-dimensional moving mechanism 251, a cover plate grabbing base 252, a cover plate rotating mechanism 253, a cover plate grabbing mechanism 254 and an angle detection mechanism 255. The cover plate grabbing base 252 is connected to the cover plate three-dimensional moving mechanism 251, and the cover plate three-dimensional moving mechanism 251 is used to drive the cover plate grabbing base 252 to move in the horizontal, longitudinal and vertical directions, wherein the horizontal and longitudinal directions can be parallel to the horizontal direction, and the horizontal and longitudinal directions are perpendicular to each other, thereby realizing the three-dimensional movement of the cover plate grabbing base 252, and accordingly, the device connected to the cover plate grabbing base 252 moves three-dimensionally with the cover plate grabbing base 252.

[0061] The cover plate rotating mechanism 253 is arranged on the cover plate grabbing base 252, the cover plate grabbing mechanism 254 is used to grab the cover plate, and the cover plate grabbing mechanism 254 is connected to the cover plate rotating mechanism 253, and the cover plate rotating mechanism 253 is used to drive the cover plate grabbing mechanism 254 to rotate, and accordingly the orientation angle of the cover plate grabbed by the cover plate grabbing mechanism 254 can be changed. The angle detection mechanism 255 is used to detect whether the orientation angle of the cover plate grabbed by the cover plate grabbing mechanism 254 is the same as the specified angle. When the orientation angle of the cover plate grabbed by the cover plate grabbing mechanism 254 is the same as the specified angle, the cover plate rotating mechanism 253 stops rotating, and the orientation angle of the cover plate grabbed by the cover plate grabbing mechanism 254 can be the same as the specified angle.

[0062] The working process of the cover plate grabbing and rotating assembly of the present embodiment is as follows: after the cover plate position orientation detection assembly detects the position and orientation angle of the cover plates dispersed on the flexible vibration assembly, the detected position and orientation angle of the cover plates are sent to the control module. The control module sends corresponding instructions to the cover plate three-dimensional moving mechanism 251 according to the detected position of the cover plate. The cover plate three-dimensional moving mechanism 251 drives the cover plate grabbing mechanism 254 to approach the cover plate, and the cover plate grabbing mechanism 254 grabs the cover plate. The cover plate three-dimensional moving mechanism 251 then drives the cover plate grabbing mechanism 254 away from the flexible vibration assembly to transfer the cover plate. Move to the specified position. When the cover is transferred to the specified position, the cover grabbing mechanism 254 releases the cover to realize the loading of the cover. In the process of the cover three-dimensional moving mechanism 251 driving the cover grabbing mechanism 254 away from the flexible vibration component, the cover rotating mechanism 253 drives the cover grabbed by the cover grabbing mechanism 254 to rotate. When the orientation angle of the cover grabbed by the cover grabbing mechanism 254 is the same as the specified angle, the cover rotating mechanism 253 stops rotating, and the orientation angle of the cover grabbed by the cover grabbing mechanism 254 can be the same as the specified angle, so that the cover with a uniform orientation angle can be output outward.

[0063] Furthermore, the cover plate grabbing mechanism 254 includes two groups of cover plate positioning posts 256. In the process of grabbing the cover plate, the cover plate three-dimensional moving mechanism 251 moves the cover plate grabbing base 252 downward in the vertical direction, and the two groups of cover plate positioning posts 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 plate, so that the cover plate can be accurately grabbed. On the other hand, since the lug is located at a specific position of the cover plate, after the cover plate is positioned by the cover plate positioning posts 256, the orientation angle of the cover plate is consistent with the orientation angle of the cover plate grabbing mechanism 254. Subsequently, only the orientation angle of the cover plate grabbing mechanism 254 needs to be adjusted to rotate the cover plate to the specified angle, so as to simplify the process and rotate the cover plate to the specified angle more quickly.

[0064] It should be noted that, since the cover position orientation detection component detects the orientation angle of the cover, the cover rotation mechanism 253 can rotate the cover grabbing mechanism 254 according to the orientation angle, so that the two groups of cover positioning columns 256 can be aligned with the positioning holes on the two lugs.

[0065] In this embodiment, the cover plate positioning column 256 may be an elastic column, which can be elastically moved in the vertical direction, so as to avoid the rigid contact between the cover plate positioning column 256 and the lug of the cover plate, thereby avoiding the damage to the cover plate.

[0066] Furthermore, the cover plate rotating mechanism 253 includes a central rotating shaft, and the cover plate rotating mechanism 253 is used to drive the central rotating shaft to rotate. The cover plate grabbing mechanism 254 is connected to the central rotating shaft, and can drive the cover plate grabbing mechanism 254 to rotate accordingly. The angle detection mechanism 255 includes a shielding disc 2551 and a slot-type photoelectric sensor 2552. The shielding disc 2551 is coaxially connected to the central rotating shaft, so that it can rotate with the central rotating shaft, and the rotation angle of the shielding disc 2551 is the same as the rotation angle of the cover plate grabbing mechanism 254. The shielding disc 2551 passes through the slot of the slot-type photoelectric sensor 2552 to block the light signal so that the photoelectric sensor 2552 is not triggered. At the same time, a light-transmitting slit is provided on the shielding disc 2551, and the angle of the light-transmitting slit on the shielding disc 2551 corresponds to the specified angle. When the light from the slot-type photoelectric sensor 2552 passes through the light-transmitting slit and causes the slot-type photoelectric sensor 2552 to be triggered, it means that the orientation angle of the cover grasped by the cover grasping mechanism 254 has been rotated to the same as the specified angle, and the cover rotating mechanism 253 can stop rotating so that the orientation angle of the cover remains the same as the specified angle.

[0067] In this embodiment, the cover plate rotating mechanism 253 may include a motor, the central rotating shaft is the output shaft of the motor, the motor output shaft can pass through the motor housing to form a double-headed motor, the shading disk 2551 can be fixed at the upper end of the output shaft, and the cover plate grabbing mechanism 254 can be fixed at the lower end of the output shaft.

[0068] In some embodiments, as Figure 8 shown, the cover plate grasping mechanism 254 further includes a cover plate magnetic adsorption head, which can generate a magnetic adsorption force to grasp the cover plate. Alternatively, the cover plate grasping mechanism 254 further includes a cover plate negative pressure adsorption head, on which negative pressure holes or negative pressure suction cups are provided, and 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 holes or negative pressure suction cups, and use the negative pressure suction force to adsorb the cover plate. Alternatively, the cover plate grasping mechanism 254 further includes cover plate clamping claws, which clamp the cover plate by approaching each other and release the cover plate by moving away from each other.

[0069] In some embodiments, as Figure 6 shown, the cover plate vibrating disk assembly 210 includes a cover plate vibrating disk, which 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, which 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 elaborated here.

[0070] In some embodiments, as Figure 6 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, and ensure that the cover plate can finally slide onto the flexible vibration assembly 230.

[0071] In some embodiments, as Figure 6 shown, the flexible vibration assembly 230 includes a flexible vibrating disk, which disperses the cover plates by the vibration generated by the flexible vibrating disk.

[0072] In some embodiments, as Figure 6 and Figure 7 shown, the cover plate position and orientation detection component 240 includes a vision detection device, which 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.

[0073] Further, 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 lower flexible vibration assembly 230, and the vision detection device may further include a fill light 242 to supplement light for the camera 241 to ensure the shooting effect.

[0074] In some embodiments, as Figure 6As shown, the automatic feeding device for motor cover plates of this embodiment further includes a cover plate material bin 260 and a cover plate feeding assembly 270. The cover plate material bin 260 is used to place cover plates, and the cover plate feeding assembly 270 is used to transport the cover plates in the cover plate material bin 260 to the cover plate vibration plate. Whenever the cover plate vibration plate works for a period of time, the cover plates in the cover plate vibration plate will decrease. The cover plate feeding assembly 270 can be used to add cover plates to the cover plate vibration plate to ensure sufficient material supply, so that the automatic feeding device for motor cover plates can work for a long time.

[0075] In this embodiment, the cover plate feeding assembly 270 may include a circulating conveyor belt and a material drop track. A material baffle plate is provided on the conveyor belt. One end of the conveyor belt extends into the cover plate silo 260, and the other end is connected to the material drop track. The material will stay on the material baffle plate, and the conveyor belt will then transport the material to the material drop track. The material will slide down along the material drop track into the cover plate vibration plate.

[0076] In some embodiments, Figure 6 As shown, a detection sensor for detecting the remaining cover in the cover vibration plate can be set in the cover vibration plate. When the detection sensor detects that the remaining cover is lower than the set value, the cover feeding assembly 270 starts working to automatically feed the cover vibration plate to ensure continuous supply of covers. The number of covers added by the cover feeding assembly 270 each time can be in a relatively stable range, and it is not advisable to add too many covers, thereby reducing the risk of scratching the cover due to multiple vibrations in the cover vibration plate, thereby improving product quality.

[0077] In some embodiments, Figure 6 As shown, the blanking chute 220 is provided with a baffle mechanism for opening or isolating the blanking chute 220, and the cover position orientation detection component 240 is also used to detect the number of cover plates on the flexible vibration component 230. When the number of cover plates is less than the preset number, the baffle mechanism is used to open the blanking chute 220 and replenish the cover plates to the flexible vibration component 230 in time.

[0078] Furthermore, a cover plate counter can be set at the output end of the cover plate vibration disk, which counts 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 fall directly onto the flexible vibration component 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 vibration disk stops operating, so that the number of cover plates entering the blanking chute 220 is relatively stable; when the cover plate position orientation detection component 240 detects that the number of cover plates on the flexible vibration component 230 is less than the preset number, the baffle mechanism opens the blanking chute 220 again, thereby replenishing a relatively stable number of cover plates to the flexible vibration component 230 each time, which not only ensures the material supply, but also avoids the accumulation of cover plates on the flexible vibration component 230, which makes it impossible to disperse the cover plates.

[0079] 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 falls, it can abut against the material drop chute, thereby blocking the material drop chute and preventing the cover plate from falling. When the baffle rises, the material drop chute can be opened, and the cover plate can normally enter the flexible vibration assembly 230 along the material drop chute.

[0080] In some embodiments, Figure 6 As shown, the cover plate position orientation detection component 240 is also used to detect the front and back sides of the cover plate on the flexible vibration component 230. When it is detected that the back side of the cover plate is facing upward, the cover plate grabbing and rotating component 250 takes away the cover plate facing upward and puts it into a dedicated collection box. Since it cannot be guaranteed that 100% of the covers output by the cover plate vibration disk are facing upward, this function of the cover plate position orientation detection component 240 can reduce the situation of incorrect cover plate installation and improve the product yield.

[0081] In some embodiments, Fig. 9 As shown, the motor conveying device includes a motor conveying track 110 extending along the conveying direction of the motor tooling 20 and a motor drive assembly 120. The motor tooling 20 is placed on the motor conveying track 110. The motor drive assembly 120 is used to drive the motor tooling 20 to slide along the motor conveying track 110, thereby conveying the motor tooling 20.

[0082] The motor conveying track 110 guides the motor fixture 20, so that the motor fixture 20 can stably move along the conveying direction and prevent the motor fixture 20 from falling. The motor drive assembly 120 can be a conveyor belt arranged along the motor conveying track 110, and the motor fixture 20 can be driven to move by the conveyor belt. Of course, the motor drive assembly 120 can also be other drive assemblies such as a push assembly that can drive the motor fixture 20 to move.

[0083] When the assembly positioning device also includes a second positioning drive component to form a fork feeding device, the motor conveying device and the assembly positioning device will cooperate to convey the motor tooling 20. Specifically, the motor conveying track 110 can be divided into three sections connected in sequence along the conveying direction, namely the first section, the second section and the third section. The first section and the third section are both configured with a motor drive component 120, so that the motor tooling 20 in the first section is conveyed to the second section. The second section cooperates with the assembly positioning device, and the assembly positioning device drives the motor tooling 20 to move on the second section of the motor conveying track 110, and then the motor tooling 20 can be conveyed to the third section again. The motor drive component 120 corresponding to the third section then drives the motor tooling 20 to continue to move backward.

[0084] In some embodiments, Figure 5 As shown, the motor tooling 20 may include a motor placement seat, the top surface of the motor placement seat is provided with a motor placement groove, and the motor product is used to be placed in the motor placement groove to move with the motor placement seat. The main body shape of the motor placement seat can be a rectangular parallelepiped to make it easier to insert between the two positioning fork rods 541.

[0085] In some embodiments, Fig.10 As shown, the cover assembly device includes a cover multi-dimensional moving component 410 and a cover grabbing component 420. The cover grabbing component 420 is connected to the cover multi-dimensional moving component 410. The cover grabbing component 420 is used to grab the cover. The cover multi-dimensional moving component 410 is used to drive the cover grabbing component 420 to move in the horizontal and vertical directions, so as to drive the cover grabbing component 420 to approach the cover on the cover transfer device. The cover grabbing component 420 can grab the cover and can also drive the cover grabbing component 420 to approach the motor product located at the cover assembly station. The cover grabbing component 420 then assembles the cover to the motor product. After the assembly is completed, the cover grabbing component 420 releases the cover.

[0086] In some embodiments, Fig.11As shown, the cover plate transfer device includes a circular transfer track 310, a transfer drive assembly 320 and a cover plate fixture 30 placed in the circular transfer track 310. The cover plate fixture 30 is used to place the cover plate 11, and the transfer drive assembly 320 is used to drive the cover plate fixture 30 to move cyclically along the circular transfer track 310. One side of the circular transfer track 310 is close to the cover plate feeding device, so that the cover plate feeding device can move the cover plate to the cover plate fixture 30 on this side of the circular transfer track 310, and the transfer drive assembly 320 then moves the cover plate fixture 30 loaded with the cover plate to the other side of the circular transfer track 310. The other side of one side of the circular transfer track 310 is close to the cover plate assembly device, and the cover plate assembly device can take away the cover plate on the cover plate fixture 30. The transfer drive assembly 320 then moves the unloaded cover plate fixture 30 to the side of the circular transfer track 310 close to the cover plate feeding device to achieve cyclic feeding.

[0087] The annular transfer track 310 may include a rectangular ring-shaped material transfer groove, in which the cover plate fixture 30 is placed. The material transfer groove is composed of four sections of linear grooves, which are sequentially connected along the conveying direction to form a rectangular ring structure. Four transfer drive assemblies 320 are provided, which are respectively arranged at the tail ends of the four sections of linear grooves to push the cover plate fixture 30 to the next linear groove, thereby, the cover plate fixture 30 circulates along the material transfer groove.

[0088] In some embodiments, Figure 2 and Figure 3 As shown, the automatic assembly machine of the motor cover of this embodiment also includes a cover detection device 600 and a defective product unloading device 700. The cover assembly station, the cover detection device 600 and the defective product unloading device 700 are arranged in sequence along the conveying direction of the motor tooling. After the cover assembly device 400 assembles the cover onto the motor product, the motor conveying device 100 moves the motor product assembled with the cover to the cover detection device 600. The cover detection device 600 is used to detect whether the cover on the motor product is assembled in place. The motor product with the cover assembled in place is a good product. On the contrary, the motor product without the cover assembled and the motor product with the cover assembled but not assembled accurately in place are both defective products. The defective product unloading device 700 is used to move the motor product with the cover not assembled in place out of the motor conveying device 100, and the motor conveying device 100 can continue to convey the good products to the subsequent stations.

[0089] In this embodiment, the cover plate detection device 600 may adopt an existing cover plate detection device, and its specific structure and principle are not described in detail.

[0090] like Fig.12As shown, the defective product unloading device may include a motor moving component 710, a motor clamping component 720 and a defective product bin 730, the defective product bin 730 is used to place defective products, the motor clamping component 720 is used to grab defective products, the motor moving component 710 is connected to the motor clamping component 720 and is used to drive the motor clamping component 720 to move in the horizontal and vertical directions, so that the motor clamping component 720 can approach the target position, thereby grabbing defective products or putting down the defective products.

[0091] In the above embodiments, both the cover plate grabbing assembly and the motor clamping assembly may include a magnetic adsorption head, which can generate a magnetic adsorption force to grab the cover plate or the motor. Alternatively, both the cover plate grabbing assembly and the motor clamping assembly may include a negative pressure adsorption head, which is provided with a negative pressure hole or a negative pressure suction cup, and the negative pressure adsorption head is also connected to a vacuum pump 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 or the motor. Alternatively, both the cover plate grabbing assembly and the motor clamping assembly may include clamping claws, which clamp the cover plate or the motor by bringing the clamping claws closer together, and release the cover plate or the motor by moving the clamping claws away from each other.
