Technical Field

The cleaning machine motor is a type of motor. The existing assembly equipment for cleaning machine motors usually includes a rotor pressing device, a screw locking device, and a fan pressing device. This kind of assembly equipment has the following disadvantages:

[0003] 1. It is impossible to achieve the alignment setting of the motor cover and the motor housing through mechanical equipment, and only manual alignment of the motor cover and the motor housing can be done. This reduces the efficiency of motor assembly. Similarly, when pressing the rotor, it is impossible to ensure the accurate alignment of the motor cover and the motor housing, which will result in an installation error between the motor cover and the motor housing, causing the screw holes of the two to be misaligned, and thus unable to perform the subsequent screw driving step.

[0004] 2. The screw locking device cannot adjust the position of screw driving, so it is impossible to drive screws to splice different specifications of motor housings and motor covers, which makes the motor assembly equipment limited.

[0005] 3. The fan pressing device, the rotor pressing device, and the screw locking device are independent devices and are in different positions. Therefore, the material needs to be transported between each processing step, which reduces the production efficiency of the motor. Summary of the Invention

[0006] The purpose of this technical solution is to provide an assembly equipment and an assembly method for a cleaning machine motor. The rotor pressing device automatically stores the auxiliary positioning pins for aligning the motor cover and the motor housing. The screw locking device adjusts the position of screw driving to suit the assembly of different models of motors. The fan installation device integrates the processes of transporting and pressing the fan on the same station, solving the problems of low production efficiency and low adaptability of the original equipment.

[0007] The purpose of this technical solution is achieved as follows:

A rotor is placed inside the motor casing, and a motor cover is arranged on the motor casing. The motor cover is inserted into the motor casing through an auxiliary positioning pin.

The rotor pressing mechanism is used to press the rotor into the motor casing through the motor cover, and the pin taking mechanism is used to remove and collect the auxiliary positioning pin after pressing the rotor.

[0016] An assembling method for a cleaning machine motor, which is based on an assembling device for the cleaning machine motor, includes the following steps:

[0017] Step S1: In the feeding stage, place the rotor into the motor housing, place the motor cover in alignment on the motor housing, and insert the auxiliary positioning pin into the set screw hole.

[0018] Step S2: Rotor pressing stage and pin removal stage. By driving the rotor pressing part to descend and press the motor cover tightly, the motor cover and the rotor are installed on the motor housing. During this process, the movement path of the nail receiving groove avoids the nail removal plate. During the process of the rotor pressing part resetting and rising, the auxiliary positioning pin is removed. Then, through the horizontal movement of the nail removal plate, the auxiliary positioning pin is withdrawn from the nail receiving groove by the pin blocking part. During this process, the nail receiving groove returns to its reset position below the nail removal plate;

[0019] Step S3: Screw locking stage. Through the lifting driving part and the first screw driving part, the screw screwing bushing carries the screw close to the screw hole on the motor cover, and the screw screwing rod is driven by the second screw driving part to complete the screwing of the screw;

[0020] Step S4: Blower blade pressing stage. The blower blade is transported to the blower blade installation position by the blower blade feeding mechanism. The motor housing is transported above the blower blade by the blower blade pressing mechanism. During the process of driving the motor housing to move downward, the blower blade is pressed at the bottom of the motor housing. Subsequently, the motor housing with the blower blade pressed is transported back to the loading seat by the blower blade pressing mechanism;

[0021] Step S5: Unloading stage. The motor housing with the blower blade pressed is grabbed by the manipulator for unloading.

[0022] Preferably, a sub-step S2-1: Diameter-changing stage is also provided between step S2 and step S3. By driving the diameter-changing linkage part to move through the diameter-changing driving part, the position of the screw screwing bushing is moved to adapt to the positions of the screw holes on the motor covers of different models.

[0023] The prominent and beneficial technical effects of this technical solution compared with the prior art are:

[0024] 1. The nail removal mechanism designed in this technical solution can remove the auxiliary positioning pins used to position the motor housing and the motor cover during the return journey after the rotor is pressed, thereby ensuring the stability during motor assembly. And while removing the auxiliary positioning pins, the collection of the auxiliary positioning pins is completed, thus forming a pipeline operation, greatly improving the production efficiency.

[0025] 2. The screw locking device designed in this technical solution can be used to screw the screws on the motor cover, and through the diameter-changing mechanism, the positions of all screw screwing operations can be adjusted synchronously, so as to adapt to the assembly of motors of different models, avoiding the singularity that the screw locking device of the original equipment can only assemble motors of one model. Moreover, synchronously adjusting the screw screwing positions can ensure that the movement error is minimized to the greatest extent, guarantee the accuracy of motor assembly, and improve the product yield.

[0026] 3. The blower blade installation device designed in this technical solution can set the motor housing and the blower blade together in the blower blade installation position and then press them, avoiding the transportation of the blower blade and the motor housing, and improving the production efficiency.

[0040] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0041] 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.

[0042] 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.

[0043] Further, a indexing table turntable 11 is rotatably arranged on the main frame 1, and a number of loading seats 12 for placing the motor housing 100 are circumferentially arranged on the indexing table 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. The motor housing 100 and the motor cover 101 can then rotate with the indexing table turntable 11 and successively reach the sides of the rotor pressing device 2, the screw locking device 3, the fan blade mounting device 4, and the unloading manipulator 6, and cooperate with each working device to complete the processing.

[0044] It should be noted that the auxiliary positioning pin 103 can be installed by mechanical equipment or manually by personnel. The placement directions of the motor housing 100 and the motor cover 101 relative to the loading seat 12 are fixed, and the fixed placement directions are to ensure the accurate docking of the screws with the screw holes on the motor cover during the subsequent screw locking step.

[0045] As Figure 2-4 shown, the rotor pressing device 2 includes a rotor pressing mechanism 21 and a pin extracting mechanism 22. The working steps of the rotor pressing device 2 have two steps. The first step is: the rotor and the motor cover 101 are pressed by the downward movement of the rotor pressing mechanism 21. The second step is: during the upward movement of the rotor pressing mechanism 21, the auxiliary positioning pin 103 is extracted and collected by the pin extracting mechanism 22. In this way, it can be ensured that the motor cover 101 and the motor housing 100 always remain in alignment during the pressing process, and it can also be ensured that after the auxiliary positioning pin 103 is extracted, screw holes are reserved for the subsequent screw driving step.

[0046] As Figure 3 shown, the rotor pressing mechanism 21 includes a rotor pressing machine frame 211, a rotor pressing driving member 212, a rotor pressing plate 213, and a rotor pressing part 215. The rotor pressing machine frame 211 is arranged on the main frame 1. The rotor pressing driving member 212 is arranged at the top of the rotor pressing machine 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 machine frame 211 through a rotor pressing guide rod 214. The rotor pressing driving member 212 can drive the rotor pressing plate 213 to move up and down, and the rotor pressing guide rod 214 can ensure the stability of the rotor pressing plate 213 during its up and down movement. The rotor pressing part 215 is arranged below the rotor pressing plate 213, and the lower end of the rotor pressing part 215 is adapted to the open end of the motor cover 101. The rotor pressing part 215 can extend into the open end of the motor cover 101 until it abuts against the motor cover 101 to press the rotor.

[0047] As 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.

[0048] 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.

[0049] 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.

[0050] Specifically, the nail receiving and installing frame 2221 is arranged on the side of the rotor press frame 211. The nail receiving groove 2222 is movably arranged on the nail receiving and installing frame 2221 through the first hinge arm 2223 and the second hinge arm 2224. The upper end of the first hinge arm 2223 is hinged to the inner side of the nail receiving and installing frame 2221, and the lower end is hinged to the middle of the nail receiving groove 2222. The upper end of the second hinge arm 2224 is hinged to the outer side of the nail receiving and installing frame 2221, and the lower end is hinged to the rear part of the nail receiving groove 2222. The cooperation of the first hinge arm 2223 and the second hinge arm 2224 can realize the inclined and stable setting of the nail receiving groove 2222. And when any hinge arm adjusts the angle, the position of the nail receiving groove 2222 can be changed. The upper end of the power arm 2225 is hinged to the rotor pressing plate 213, and the lower end is hinged to the middle of the first hinge arm 2223. In this way, when the rotor pressing plate 213 descends, the power arm 2225 pushes the first hinge arm 2223 outwards, and the first hinge arm 2223 pushes the nail receiving groove 2222 outwards, so that the nail receiving groove 2222 moves away from the nail taking plate 2213 to avoid the movement path of the auxiliary positioning pin 103. Similarly, when the rotor pressing plate 213 ascends, the power arm 2225 drives the nail receiving groove 2222 to move inwards through the first hinge 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.

[0051] The upper end of the pin blocking part 2226 is fixedly arranged on the nail taking and installing frame 2211, and the lower end extends into the nail taking groove 2214 and is located on the horizontal movement path of the auxiliary positioning pin 103. In this way, when the nail taking driving part 2212 drives the auxiliary positioning pin 103 to move towards the pin blocking part 2226, the auxiliary positioning pin 103 is blocked by the pin blocking part 2226 and then falls off from the nail taking groove 2214 and simultaneously falls into the nail receiving groove 2222.

[0052] As Figure 2 、 Figures 5-7 shown, the screw locking device 3 includes a screw locking mechanism 31 and a diameter-changing mechanism 32. The screw locking mechanism 31 is used for screwing screws onto the motor cover 101 and the motor housing 100. The diameter-changing mechanism 32 is used for adjusting the working position of the screw locking mechanism 31 to adapt to different models of the motor housing 100 and the motor cover 101.

[0053] As Figures 5-7As shown in the figure, the screw locking mechanism 31 includes a screw lifting assembly 311 and a screw screwing assembly 312. The screw lifting assembly 311 is used to drive the screw to lift so that the screw approaches the screw hole on the motor cover 101. The screw screwing assembly 312 is used to screw in the screw. The screw lifting assembly 311 includes a lifting frame 3111, a lifting driving member 3112, lifting slide rails 3113, lifting sliders 3114 and a lifting mounting plate 3115. The lifting frame 3111 is arranged on the main frame 1. The lifting driving member 3112 is arranged on the lifting frame 3111. The lifting slide rails 3113 are arranged on both sides of the lifting frame 3111. The lifting sliders 3114 are arranged on the lifting slide rails 3113. The lifting mounting plate 3115 is arranged on the lifting sliders 3114 and is connected to the output end of the lifting driving member 3112. At the same time, the screw screwing assembly 312 is arranged on the lifting sliders 3114. In this way, the lifting driving member 3112 can drive the screw screwing assembly 312 to lift and move through the lifting sliders 3114.

[0054] As Figure 6 shown in the figure, the screw screwing assembly 312 includes a first screwing mounting plate 3121, a first screwing driving member 3122, a second screwing mounting plate 3123, a second screwing driving member 3124, a screw screwing bushing 3126 and a screw screwing rod 3125. The first screwing mounting plate 3121 and the first screwing driving member 3122 cooperate to drive the second screwing mounting plate 3123 and the second screwing driving member 3124 to lift and move. The second screwing driving member 3124 is used to drive the screw screwing rod 3125 to rotate and drive the screw. The screw screwing bushing 3126 is used to store the screw.

[0055] In the embodiment of the present application, the number of the second screwing driving members 3124, the screw screwing bushings 3126 and the screw screwing rods 3125 are all set to four. In this way, four screws can be screwed simultaneously during actual work. These four screws are respectively located at the four corners of the motor cover. The lower end of the screw screwing rod 3125 is inserted into the screw screwing bushing 3126. The lower end of the screw is clamped at the opening at the bottom of the screw screwing bushing 3126. When the variable diameter mechanism 32 is not installed, the screw screwing bushing 3126 is fixedly arranged on the first screwing mounting plate 3121. Therefore, when the positions of the second screwing driving member 3124 and the screw screwing rod 3125 are determined, screws can only be driven at the same position.

[0056] Furthermore, the first screwing mounting plate 3121 is arranged on the lifting mounting plate 3115. The first screwing driving member 3122 is arranged on the first screwing mounting plate 3121. The second screwing mounting plate 3123 is arranged at the output end of the first screwing driving member 3122. The second screwing driving member 3124 is arranged on the second screwing mounting plate 3123. The screw screwing rod 3125 is arranged at the output end of the second screwing driving member 3124. The screw screwing bushing 3126 is arranged on the first screwing mounting plate 3121.

[0057] Further, the screwing mounting plate two 3123 is movably arranged on the lifting slide rail 3113 in the same way as the screwing mounting plate one 3121 is arranged on the lifting slide rail 3113. The lower end of the screw screwing rod 3125 extends into the screw screwing sleeve 3126. The screw screwing sleeve 3126 has a screw feeding port 3127. After the screwing driving part one 3122 drives the screw screwing rod 3125 to rise, the screw can be placed through the screw feeding port 3127 and clamped in the screw screwing sleeve 3126. After the lifting driving part 3112 drives the screw screwing sleeve 3126 to descend close to the screw driving position, the screwing driving part two 3124 drives the screw screwing rod 3125 to rotate to complete the screw driving.

[0058] As Figure 7 shown, the diameter-changing mechanism 32 includes a diameter-changing driving part 321, a diameter-changing mounting plate 322, several diameter-changing mounting rods 323, a diameter-changing sleeve 324 and a diameter-changing linkage part 325. The diameter-changing mechanism 32 is used to synchronously change the position of the screw screwing sleeve 3126 so as to change the screw driving position to adapt to different models of the motor housing 100 and the motor cover 101. The diameter-changing driving part 321 is arranged on the screwing mounting plate one 3121, and the diameter-changing mounting plate 322 is arranged on the lifting mounting plate 3115. In this application, the number of the diameter-changing mounting rods 323 is set to four. One of them is connected to the output end of the diameter-changing driving part 321, and the other three are respectively located at the corners of the diameter-changing mounting plate 322. And these four diameter-changing mounting rods 323 are arranged in a "cross" shape. One end of these diameter-changing mounting rods 323 is rotatably arranged on the diameter-changing mounting plate 322, and the other end is connected to the output end of the diameter-changing driving part 321 or the screwing mounting plate one 3121. The diameter-changing sleeves 324 are respectively sleeved outside the corresponding diameter-changing mounting rods 323, and the diameter-changing linkage part 325 is sequentially sleeved outside all the diameter-changing sleeves 324 to realize the linkage of all the diameter-changing sleeves 324. At the same time, the screw screwing sleeve 3126 is arranged on the diameter-changing linkage part 325. When the diameter-changing driving part 321 drives the diameter-changing linkage part 325 to move through the diameter-changing 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 mode of all the screw screwing sleeves 3126 can make them move synchronously inwards by contraction or outwards by expansion.

[0059] Further, in order to cooperate with the variable-diameter mechanism 32, a screwing coupling 326 is provided between the screw screwing rod 3125 and the second screwing driving member 3124. The screwing coupling 326 can not only realize its rotation but also its horizontal movement. In order to increase the stability of the variable diameter of the screw screwing bushing 3126, a variable-diameter slide rail 327, a variable-diameter slider 328 and a variable-diameter clamping plate 329 are also added. The variable-diameter slide rail 327 is arranged on the variable-diameter mounting plate 322, the variable-diameter slider 328 is arranged on the variable-diameter slide rail 327, the variable-diameter clamping plate 329 is clamped on the variable-diameter linkage member 325 and is arranged on the variable-diameter slider 328, and the screw screwing bushing 3126 is arranged on the variable-diameter clamping plate 329. The variable-diameter linkage member 325 drives the screw screwing bushing 3126 to move through the variable-diameter clamping plate 329. The variable-diameter slide rail 327, the variable-diameter slider 328 and the variable-diameter clamping plate 329 can play a guiding role when the screw screwing bushing 3126 moves, increasing the stability of its movement.

[0060] Furthermore, the screw locking device 3 further includes a receiving tray 33 rotatably arranged on the lifting frame 3111. The receiving tray 33 is located between the motor cover and the screw screwing bushing 3126. The receiving tray 33 can move below the screw screwing bushing 3126. At this time, the screw screwing rod 3125 moves downward. Since the lifting driving members of the screw screwing bushing 3126 and the screw screwing rod 3125 are different, the screw screwing bushing 3126 can be fixed, so that the screw stuck in the screw screwing bushing 3126 can be dredged and collected by the receiving tray 33.

[0061] As Figure 2 and Figure 8 shown, the fan blade mounting device 4 includes a fan blade press-fitting mechanism 41 and a fan blade picking mechanism 42. The fan blade press-fitting mechanism 41 has a fan blade mounting position 412. The fan blade picking mechanism 42 is used to pick up the fan blade and place it in the fan blade mounting position 412. The fan blade press-fitting mechanism 41 is used to transfer the motor housing 100 from the loading seat 12 to above the fan blade mounting 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.

[0062] Specifically, both the fan pressing mechanism 41 and the fan material taking mechanism 42 can achieve horizontal movement and vertical lifting, and the two can achieve synchronous horizontal movement. The fan pressing mechanism 41 includes a fan pressing machine frame 411, a motor horizontal movement component 413, a motor vertical lifting component 414, and a motor grasping component 415. The fan pressing machine frame 411 is arranged on the main frame 1, the fan installation position 412 is arranged on the fan pressing machine frame 411, the motor horizontal movement component 413 is arranged on the motor pressing machine frame, the motor vertical lifting component 414 is arranged on the motor horizontal component, and the motor grasping component 415 is arranged at the lower end of the motor vertical lifting component 414 for carrying the motor housing 100 and the motor cover 101 to move and place them in the fan installation position 412. The motor horizontal movement component 413 and the motor vertical lifting component 414 both achieve movement through driving parts, slide rails, sliders, and sliding plates, which will not be elaborated here. The motor grasping component 415 has an inner support type jaw and can grasp the motor cover to realize the transfer of the entire motor.

[0063] The fan material taking mechanism 42 includes a fan horizontal movement component 421, a fan vertical lifting component 422, and a fan adsorption component 423. The fan horizontal movement component 421 is arranged on the fan pressing machine frame 411, the fan vertical lifting component 422 is arranged on the fan horizontal component, and the fan adsorption component 423 is arranged at the lower end of the fan vertical lifting component 422 for carrying the fan to move and place it in the fan installation position 412. The fan horizontal movement component 421 and the fan vertical lifting component 422 also achieve movement through driving parts, slide rails, sliders, and sliding plates, which will not be elaborated here. The fan adsorption component 423 adsorbs the fan through a suction cup.

[0064] Furthermore, the fan installation position 412 is actually a receiving groove. In this application, the number of receiving grooves is set to two, which are respectively applicable to different models of fans. By controlling the horizontal movement distance of the fan pressing mechanism 41 and the fan material taking mechanism 42, cooperation with different receiving grooves can be achieved.

[0065] An assembly method for a cleaning machine motor, which is based on an assembly device for a cleaning machine motor, is characterized by including the following steps:

[0066] Step S1: In the feeding stage, place the rotor into the motor housing, place the motor cover in alignment on the motor housing, and insert the auxiliary positioning pin into the set screw hole.

[0067] Step S2: Rotor pressing stage and pin taking stage. By driving the rotor pressing part to descend and press the motor cover tightly, the motor cover and the rotor are installed on the motor housing. During this process, the movement path of the nail receiving groove avoids the nail taking plate. During the process of the rotor pressing part resetting and rising, the auxiliary positioning pin is taken out. Then, through the horizontal movement of the nail taking plate, the auxiliary positioning pin is withdrawn from the nail receiving groove by the pin blocking part. During this process, the nail receiving groove returns to its reset position below the nail taking plate;

[0068] Step S3: Screw locking stage. Through the lifting driving part and the first screw driving part, the screw screwing bushing carries the screw close to the screw hole on the motor cover, and the screw screwing rod is driven by the second screw driving part to complete the screwing of the screw;

[0069] Step S4: Blower blade pressing stage. The blower blade is transported to the blower blade installation position by the blower blade feeding mechanism. The motor housing is transported above the blower blade by the blower blade pressing mechanism. During the process of driving the motor housing to move downward, the blower blade is pressed at the bottom of the motor housing. Subsequently, the motor housing with the blower blade pressed is transported back to the loading seat by the blower blade pressing mechanism;

[0070] Step S5: Unloading stage. The motor housing with the blower blade pressed is grabbed by the manipulator for unloading.

[0071] A sub-step S2-1: Diameter changing stage is also set between step S2 and step S3. By driving the diameter changing linkage part to move through the diameter changing driving part, the position of the screw screwing bushing is moved to adapt to the positions of the screw holes on motor covers of different models.
