It is also impossible to ensure the accurate alignment of the motor cover and the motor housing when pressing the rotor. This will cause installation errors between the motor cover and the motor housing, resulting in the inability to align the screw holes of the two, and then the subsequent screwing steps cannot be carried out.

[0028] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the assembly equipment in the present application is used to assemble a cleaning machine motor, which has a fan blade 105 at the bottom. The assembly process is as follows: first, the rotor 102 is placed in the motor housing 100, and then the motor cover 101 is installed on the motor housing 100, and at the same time, the auxiliary positioning pin 103 is inserted into the motor housing 100 through the motor cover 101. After the rotor and the motor cover 101 are pressed, the auxiliary positioning pin 103 is removed, and the motor cover 101 and the motor housing 100 are screwed with screws 104. The screw holes for the screwing operation are also the plug-in holes for the auxiliary positioning pin 103. Finally, the fan blade and the motor housing 100 are moved to the specified positions respectively, and the fan blade 105 is placed under the motor housing 100. When the motor housing 100 is pressed down, the fan blade can be installed under the motor housing 100. At this point, the assembly of the motor is completed, and finally the assembled motor is grabbed by a robot for unloading.

[0030] like Figure 2 As shown, an assembly device for a cleaning machine motor includes a main frame 1, a rotor pressing device 2, a screw locking device 3 and a fan blade installation device 4. The rotor pressing device 2, the screw locking device 3 and the fan blade installation device 4 are all arranged on the main frame 1. A fan blade storage rack 5 and a blanking robot 6 are also arranged on the side of the main frame 1. The rotor pressing device 2 is used to press the motor cover 101 and the rotor 102, and is also used to remove the auxiliary positioning pins 103. The screw locking device 3 is used to screw the motor cover 101 to fix it on the motor housing 100. The fan blade installation device 4 is used to install the fan blade at the bottom of the motor housing 100. The fan blade storage rack 5 is used to store fan blades, and the blanking robot 6 is used to transport finished products.

[0031] Furthermore, a dividing plate turntable 11 is rotatably arranged on the main frame 1, and a plurality of loading seats 12 for placing the motor housing 100 are circumferentially arranged on the dividing plate turntable 11. When the motor housing 100 is placed in the loading seat 12, the position of the motor housing 100 relative to the loading seat 12 is fixed, and the motor housing 100 and the motor cover 101 can rotate with the dividing plate turntable 11, and reach the side of the rotor pressing device 2, the screw locking device 3, the fan blade installation device 4 and the unloading robot 6 in turn, and cooperate with each working device to complete the processing.

[0032] It should be noted that the auxiliary positioning pin 103 can be installed by mechanical equipment or manually. The placement direction of the motor housing 100 and the motor cover 101 is fixed relative to the loading seat 12. The fixed placement direction is to ensure that the screws are accurately connected with the screw holes on the motor cover during the subsequent screw locking step.

[0033] like Figure 2-4 As shown, the rotor pressing device 2 includes a rotor pressing mechanism 21 and a nail removing mechanism 22. The working steps of the rotor pressing device 2 have two steps. The first step is: completing the pressing of the rotor and the motor cover 101 by descending the rotor pressing mechanism 21, and the second step is: during the rising process of the rotor pressing mechanism 21, the auxiliary positioning pins 103 are extracted and collected by the nail removing mechanism 22. In this way, it can be ensured that during the pressing process, the motor cover 101 and the motor housing 100 always remain aligned, and it can also be ensured that after the auxiliary positioning pins 103 are extracted, screw holes are reserved for the subsequent screw driving steps.

[0034] like Figure 3 As shown, the rotor pressing mechanism 21 includes a rotor pressing frame 211, a rotor pressing driving member 212, a rotor pressing plate 213 and a rotor pressing portion 215. The rotor pressing frame 211 is arranged on the main frame 1, the rotor pressing driving member 212 is arranged on the top of the rotor pressing frame 211, the rotor pressing plate 213 is arranged at the output end of the rotor pressing driving member 212, and the rotor pressing plate 213 is movably arranged on the rotor pressing frame 211 through a rotor pressing guide rod 214. The rotor pressing driving member 212 can drive the rotor pressing plate 213 to rise and fall, and the rotor pressing guide rod 214 can ensure the stability of the rotor pressing plate 213 when it is raised and lowered. The rotor pressing portion 215 is arranged below the rotor pressing plate 213, and the lower end of the rotor pressing portion 215 is adapted to the opening of the motor cover 101. The rotor pressing portion 215 can extend into the opening of the motor cover 101 until it abuts against the motor cover 101 to press the rotor.

[0035] like Figure 4As shown, the nail removing mechanism 22 includes a nail removing component 221 and a nail collecting component 222. The working steps of the nail removing mechanism 22 have two steps. The first step is: taking out the auxiliary positioning pin 103 through the nail removing component 221, and the second step is: making the auxiliary positioning pin 103 fall off through the nail collecting component 222, and then completing the collection of the auxiliary positioning pin 103. In this way, the collection of the auxiliary positioning pin 103 can be completed by mechanical equipment, avoiding manual collection, and greatly increasing production efficiency.

[0036] Furthermore, the nail removal assembly 221 includes a nail removal mounting frame 2211, a nail removal driving member 2212 and a nail removal plate 2213. The nail removal mounting frame 2211 is arranged on the rotor pressing plate 213, and the nail removal mounting frame 2211 can follow the rotor pressing plate 213 to rise and fall. The nail removal driving member 2212 is arranged on the nail removal mounting frame 2211, and the nail removal plate 2213 is arranged at the output end of the nail removal driving member 2212, so that the nail removal plate 2213 can be driven to rise and fall by the nail removal mounting frame 2211, and can also be driven to translate by the nail removal driving member 2212. The nail removal plate 2213 has a nail removal groove 2214. During the movement of the nail removal plate 2213, the auxiliary positioning pin 103 can be entered from below, and the auxiliary positioning pin 103 can be clamped in the nail removal groove 2214. When the nail removal plate 2213 rises upward, the auxiliary positioning pin 103 can be taken out.

[0037] Furthermore, the nail receiving assembly 222 includes a nail receiving mounting frame 2221, a nail receiving slot 2222 and a pin blocking portion 2226. The pin blocking portion 2226 is used to push the auxiliary positioning pin 103 out of the nail taking slot 2214 to allow it to fall freely. The nail receiving slot 2222 automatically avoids when the nail taking plate 2213 descends, and automatically moves to the bottom of the nail taking plate 2213 when the nail taking plate 2213 rises, so as to ensure that the auxiliary positioning pin 103 can fall into the nail receiving slot 2222.

[0038] Specifically, the nail receiving mounting frame 2221 is arranged on the side of the rotor pressing frame 211, and the nail receiving slot 2222 is movably arranged on the nail receiving mounting frame 2221 through the hinged arm 1 2223 and the hinged arm 2224. The upper end of the hinged arm 1 2223 is hinged to the inner side of the nail receiving mounting frame 2221, and the lower end is hinged to the middle part of the nail receiving slot 2222. The upper end of the hinged arm 2224 is hinged to the outer side of the nail receiving mounting frame 2221, and the lower end is hinged to the rear part of the nail receiving slot 2222. The cooperation of the hinged arm 1 2223 and the hinged arm 2 2224 can realize the inclined and stable setting of the nail receiving slot 2222, and when any hinged arm adjusts its angle, the position of the nail receiving slot 2222 can be changed, and the power arm 2225 The upper end is hinged on the rotor pressing plate 213, and the lower end is hinged on the middle part of the articulated arm 2223. In this way, when the rotor pressing plate 213 descends, the power arm 2225 pushes the articulated arm 2223 outward, and the articulated arm 2223 pushes the nail receiving groove 2222 outward, so that the nail receiving groove 2222 moves away from the nail removing plate 2213 to avoid the movement path of the auxiliary positioning pin 103. Similarly, when the rotor pressing plate 213 rises, the power arm 2225 drives the nail receiving groove 2222 to move inward through the articulated arm 2223 until the nail receiving groove 2222 is located below the auxiliary positioning pin 103. In this way, when the auxiliary positioning pin 103 is pushed out, the auxiliary positioning pin 103 can be collected.

[0039] The upper end of the pin blocking portion 2226 is fixedly set on the nail removal mounting frame 2211, and the lower end extends into the nail removal slot 2214 and is located on the horizontal movement path of the auxiliary positioning pin 103. In this way, when the nail removal driving member 2212 drives the auxiliary positioning pin 103 to move toward the pin blocking portion 2226, the auxiliary positioning pin 103 is blocked by the pin blocking portion 2226 and falls off from the nail removal slot 2214, and falls into the nail collection slot 2222 at the same time.

[0040] like Figure 2 , Figure 5-7 As shown, the screw locking device 3 includes a screw locking mechanism 31 and a diameter reducing mechanism 32. The screw locking mechanism 31 is used to screw into the motor cover 101 and the motor housing 100, and the diameter reducing mechanism 32 is used to adjust the working position of the screw locking mechanism 31 to adapt to different models of motor housings 100 and motor covers 101.

[0041] like Figure 5-7As shown, the screw locking mechanism 31 includes a screw lifting component 311 and a screw twisting component 312. The screw lifting component 311 is used to drive the screw to lift so that the screw is close to the screw hole on the motor cover 101. The screw twisting component 312 is used to screw in the screw. The screw lifting component 311 includes a lifting frame 3111, a lifting drive member 3112, a lifting slide rail 3113, a lifting slider 3114 and a lifting installation plate 3115. The lifting frame 3111 is arranged on the main frame 1, the lifting drive member 3112 is arranged on the lifting frame 3111, the lifting slide rail 3113 is arranged on both sides of the lifting frame 3111, and the lifting slide rail 3113 is provided with a lifting slider 3114. The lifting installation plate 3115 is arranged on the lifting slider 3114 and connected to the output end of the lifting drive member 3112. At the same time, the screw twisting component 312 is arranged on the lifting slider 3114, so that the lifting drive member 3112 can drive the screw twisting component 312 to move up and down through the lifting slider 3114.

[0042] like Figure 6 As shown, the screw tightening assembly 312 includes a screwing mounting plate 1 3121, a screwing driving member 1 3122, a screwing mounting plate 2 3123, a screwing driving member 2 3124, a screw tightening sleeve 3126 and a screw tightening rod 3125. The screwing mounting plate 1 3121 and the screwing driving member 1 3122 cooperate to drive the screwing mounting plate 2 3123 and the screwing driving member 2 3124 to move up and down. The screwing driving member 2 3124 is used to drive the screw tightening rod 3125 to rotate and screw, and the screw tightening sleeve 3126 is used to store screws.

[0043] In an embodiment of the present application, the number of the screwing drive member 2 3124, the screw screwing sleeve 3126 and the screw screwing rod 3125 are all set to four, so that four screws can be screwed at the same time in actual work. The four screws are respectively located at the four corners of the motor cover, and the lower end of the screw screwing rod 3125 is inserted into the screw screwing sleeve 3126, and the lower end of the screw is clamped in the opening at the bottom of the screw screwing sleeve 3126. When the reducing mechanism 32 is not installed, the screw screwing sleeve 3126 is fixedly set on the screw mounting plate 1 3121, so when the positions of the screwing drive member 2 3124 and the screw screwing rod 3125 are determined, the screws can only be driven in at the same position.

[0044] Furthermore, the screwing mounting plate 1 3121 is arranged on the lifting mounting plate 3115, the screwing driving component 1 3122 is arranged on the screwing mounting plate 1 3121, the screwing mounting plate 2 3123 is arranged on the output end of the screwing driving component 1 3122, the screwing driving component 2 3124 is arranged on the screwing mounting plate 2 3123, the screw screwing rod 3125 is arranged on the output end of the screwing driving component 2 3124, and the screw screwing sleeve 3126 is arranged on the screwing mounting plate 1 3121.

[0045] Furthermore, the screwing mounting plate 2 3123 is movably arranged on the lifting rail 3113, and its arrangement method is the same as the arrangement method of the screwing mounting plate 1 3121 on the lifting rail 3113. The lower end of the screw screwing rod 3125 is extended into the interior of the screw screwing sleeve 3126. The screw screwing sleeve 3126 has a screw loading port 3127. After the screw driving member 1 3122 drives the screw screwing rod 3125 to rise, the screw can be inserted from the screw loading port 3127 and clamped in the screw screwing sleeve 3126. After the lifting driving member 3112 drives the screw screwing sleeve 3126 to descend close to the screw driving position, the screw driving member 2 3124 drives the screw screwing rod 3125 to rotate to complete the screw driving.

[0046] like Figure 7 As shown, the reducing mechanism 32 includes a reducing drive member 321, a reducing mounting plate 322, a plurality of reducing mounting rods 323, a reducing shaft sleeve 324 and a reducing linkage member 325. The reducing mechanism 32 is used to synchronously change the position of the screw-twisting shaft sleeve 3126 so that the screw-driving position is changed to adapt to different types of motor housings 100 and motor covers 101. The reducing drive member 321 is arranged on the screwing mounting plate 3121, and the reducing mounting plate 322 is arranged on the lifting mounting plate 3115. In the present application, the number of reducing mounting rods 323 is set to four, one of which is connected to the output end of the reducing drive member 321, and the other three are respectively located at the corners of the reducing mounting plate 322, and the four reducing mounting rods 323 are arranged in a "cross" shape. One end of the rod 323 is rotatably set on the reducing mounting plate 322, and the other end is connected to the output end of the reducing driving member 321 or the screw mounting plate 1 3121. The reducing sleeves 324 are respectively sleeved on the outside of the corresponding reducing mounting rods 323, and the reducing linkage member 325 is sequentially sleeved on the outside of all the reducing sleeves 324 to realize the linkage of all the reducing sleeves 324. At the same time, the screw screwing sleeve 3126 is set on the reducing linkage member 325. When the reducing driving member 321 drives the reducing linkage member 325 to move through the reducing sleeve 324, it can drive the adjustment of the working position of the screw screwing sleeve 3126 and realize the linkage of all the screw screwing sleeves 3126. It should be noted that the setting method of all the screw screwing sleeves 3126 can make them synchronously contract inward or expand outward.

[0047] Furthermore, in order to cooperate with the diameter reducing mechanism 32, we set a screw coupling 326 between the screw screw rod 3125 and the screw driving member 2 3124. The screw coupling 326 can realize its rotation and horizontal movement. In order to increase the stability of the screw screw sleeve 3126 when the diameter is reduced, we also add a diameter reducing slide rail 327, a diameter reducing slider 328 and a diameter reducing clamping plate 329. The diameter reducing slide rail 327 is set on the diameter reducing mounting plate 322. The slider 328 is set on the reducing slide rail 327, the reducing clamp 329 is clamped on the reducing linkage part 325 and is set on the reducing slider 328, the screw turning sleeve 3126 is set on the reducing clamp 329, and the reducing linkage part 325 drives the screw turning sleeve 3126 to move through the reducing clamp 329. The reducing slide rail 327, the reducing slider 328 and the reducing clamp 329 can play a guiding role when the screw turning sleeve 3126 moves, thereby increasing the stability of its movement.

[0048] Furthermore, the screw locking device 3 also includes a receiving tray 33 rotatably arranged on the lifting frame 3111, and the receiving tray 33 is located between the motor cover and the screw turning sleeve 3126. The receiving tray 33 can be moved to the bottom of the screw turning sleeve 3126, and at this time, the screw turning rod 3125 moves downward. Since the lifting and lowering drive parts of the screw turning sleeve 3126 and the screw turning rod 3125 are different, the screw turning sleeve 3126 can be fixed, so that the screw stuck in the screw turning sleeve 3126 can be cleared and collected by the receiving tray 33.

[0049] like Figure 2 and Figure 8 As shown, the fan blade installation device 4 includes a fan blade pressing mechanism 41 and a fan blade picking mechanism 42. The fan blade pressing mechanism 41 has a fan blade installation position 412. The fan blade picking mechanism 42 is used to pick up the fan blade and place it in the fan blade installation position 412. The fan blade pressing mechanism 41 is used to transfer the motor housing 100 from the loading seat 12 to above the fan blade installation position 412, and then drive the motor housing 100 to move downward to complete the assembly of the fan blade, and is also used to transfer the assembled motor housing 100 back to the loading seat 12.

[0050] Specifically, the fan blade pressing mechanism 41 and the fan blade picking mechanism 42 can both realize horizontal movement and vertical lifting, and the two can realize synchronous horizontal movement. The fan blade pressing mechanism 41 includes a fan blade pressing frame 411, a motor horizontal movement component 413, a motor vertical lifting component 414 and a motor grabbing component 415. The fan blade pressing frame 411 is arranged on the main frame 1, the fan blade installation position 412 is arranged on the fan blade pressing frame 411, the motor horizontal movement component 413 is arranged on the motor pressing frame, and the motor The vertical lifting assembly 414 is arranged on the motor horizontal assembly, and the motor grabbing assembly 415 is arranged at the lower end of the motor vertical lifting assembly 414, and is used to carry the motor housing 100 and the motor cover 101 to move so that they are placed in the fan blade installation position 412. The motor horizontal moving assembly 413 and the motor vertical lifting assembly 414 are both moved by driving parts, slide rails, sliders and slide plates, which will not be elaborated here. The motor grabbing assembly 415 has an internal support claw that can grab the motor cover to realize the transportation of the entire motor.

[0051] The fan blade picking mechanism 42 includes a fan blade horizontal moving component 421, a fan blade vertical lifting component 422 and a fan blade suction component 423. The fan blade horizontal moving component 421 is arranged on the fan blade pressing frame 411, the fan blade vertical lifting component 422 is arranged on the fan blade horizontal component, and the fan blade suction component 423 is arranged at the lower end of the fan blade vertical lifting component 422, which is used to carry the fan blade to move and place it in the fan blade installation position 412. The fan blade horizontal moving component 421 and the fan blade vertical lifting component 422 are also moved by driving parts, slide rails, sliders and slide plates, which will not be elaborated here. The fan blade suction component 423 suctions the fan blade through a suction cup.

[0052] Furthermore, the fan blade installation position 412 is actually a receiving groove. In the present application, the number of receiving grooves is set to two, which are respectively suitable for fan blades of different models. By controlling the horizontal movement distance of the fan blade pressing mechanism 41 and the fan blade picking mechanism 42, it can be coordinated with different receiving grooves.

During this process, the nail collecting groove avoids the movement path of the nail removing plate. During the process of the rotor pressing part returning to the original position and rising, the auxiliary positioning pin is removed. Then, the auxiliary positioning pin is withdrawn from the nail removing groove by the pin blocking part through the horizontal movement of the nail removing plate. During this process, the nail collecting groove returns to the bottom of the nail removing plate. Step S3: During the screw locking stage, the screw-tightening sleeve carries the screw close to the screw hole on the motor cover by lifting the driving member and screwing the driving member 1, and the screw-tightening rod is driven by screwing the driving member 2 to complete the screwing; Step S4: During the fan blade pressing stage, the fan blade is transferred to the fan blade installation position by the fan blade taking mechanism, and the motor housing is transferred to the top of the fan blade by the fan blade pressing mechanism. In the process of driving the motor housing to move downward, the fan blade is pressed onto the bottom of the motor housing, and then the motor housing with the fan blade pressed is transferred back to the loading seat by the fan blade pressing mechanism. Step S5: in the blanking stage, the motor housing with the fan blades pressed and installed is blanked by grabbing with a robot.

[0054] A sub-step S2-1 is also provided between step S2 and step S3: in the diameter changing stage, the diameter changing driving member drives the diameter changing linkage member to move, thereby realizing the movement of the screw-tightening sleeve position to adapt to the position of the screw hole on the motor cover of different models.
