Description

Technical Field

[0001] The present invention relates to the technical field of polishing, and in particular to a polishing device for a servo motor housing. Background Art

[0002] A polishing device is a device used for surface treatment, aiming to make the material surface smooth and shiny through physical or chemical means. Polishing is usually used for various materials such as metals, plastics, glasses, ceramics, etc., to achieve the effects of beauty and improvement of surface performance.

[0003] The patent with the publication number CN212071509U discloses a surface polishing device for a motor housing, including a workbench. Lifting mechanisms are arranged on both sides of the top of the workbench. A fixing frame is arranged at the top of the lifting mechanism. A moving mechanism is arranged on the right side of the inner cavity of the fixing frame. A polishing mechanism is arranged at the bottom of the moving mechanism. A placement table is fixedly connected to the top of the workbench. By placing the housing on the top of the placement table, turning on the second motor, the second motor finally drives two clamps to move towards each other to fix the housing, and turning on the motor and the cylinder to polish the housing, the purpose of convenient use is achieved. This surface polishing device for a motor housing has the advantage of convenient use. It does not require the user to hold a polishing machine for work, saving manpower, and mechanically fixing the housing, significantly improving the stability of the housing during the polishing process, and thus improving the polishing quality. However, this device can only perform single grinding and polishing. Generally, the motor housing will be welded before polishing and painted after polishing. And this device needs to perform three processes before and after to complete welding, polishing, and painting, with low working efficiency. Therefore, a polishing device for a servo motor housing is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a polishing device for a servo motor housing in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a polishing device for a servo motor housing, including a protective frame. An inner wall of the protective frame is provided with a transfer table. A welding machine, a polishing machine and a spraying machine are respectively installed at the top of the protective frame. The welding machine, the polishing machine and the spraying machine are arranged in sequence from left to right. A plurality of welding heads are provided at the front of the welding machine, and the plurality of welding heads are fixed and penetrate through the front of the protective frame. A plurality of nozzles are provided at the rear of the spraying machine, and the plurality of nozzles are fixed and penetrate through the rear of the protective frame; a clamping mechanism is provided on the inner wall of the protective frame, a positioning mechanism is provided on the inner wall of the protective frame, and a collection mechanism is provided on the inner wall of the protective frame; the clamping mechanism includes a motor, a bidirectional screw rod, a guide rod, a moving plate, a clamping plate, a fixing plate, a sponge block, a transmission plate, a roller and a brush plate. The motor is fixedly connected to the front of the protective frame, the bidirectional screw rod is fixedly connected to the output end of the motor, the guide rod is fixedly connected to the inner wall of the protective frame, the moving plate is threadedly connected to the circumferential surface of the bidirectional screw rod, the clamping plate is fixedly connected to the bottom of the moving plate, the fixing plate is fixedly connected to the inner wall of the protective frame, the sponge block is installed at the bottom of the fixing plate, the transmission plate is fixedly connected to the top of the clamping plate, the roller is rotatably connected to the right side of the transmission plate, and the brush plate is fixedly connected to the axis of the roller; the circumferential surface of the bidirectional screw rod is rotatably connected to the inner wall of the protective frame, the inner wall of the moving plate is slidably connected to the circumferential surface of the guide rod, the bottom of the clamping plate contacts the transfer table. The motor housing is placed into the device from the left side of the device, and the motor housing moves to the right on the transfer table. When the motor housing moves below the welding machine, the welding machine will weld the motor housing. Then it continues to move under the polishing machine, and the polishing machine will polish it. The polished motor housing will contact the sponge block, and the sponge block will clean the polishing debris on the surface of the motor housing to prevent subsequent debris from affecting the spraying of the motor housing. Then when the motor housing is transported below the spraying machine, the spraying machine will spray the motor housing. Thus, the integration of welding, polishing, cleaning and spraying of the motor housing can be realized, without the need for multiple processes to work separately, improving the work efficiency. At the same time, when the transfer table transports the motor housing below the polishing machine, the transfer table stops operating and the motor starts. The motor drives the bidirectional screw rod to rotate, and the bidirectional screw rod drives the two moving plates to gather on the surface of the guide rod. The moving plates drive the clamping plates to move and clamp the motor housing on the transfer table to prevent the motor housing from shaking during the polishing process, thereby affecting its polishing quality. When the clamping plate moves, it will drive the transmission plate to move, the transmission plate drives the roller to move, the roller moves on the surface of the fixing plate and rotates itself while moving through friction, and the roller drives the brush plate to rotate. The brush plate rotates to knock off the debris and dust adhered to the bottom of the sponge block to prevent excessive accumulation of debris after long-term use of the sponge block, which will affect the subsequent cleaning effect of the polished motor housing.

[0006] Preferably, the positioning mechanism includes a support rod, a rotating plate, a push rod, a top rod, a sliding plate, an elastic telescopic rod, and a positioning plate. The support rod is fixedly connected to the front and rear sides of the protective frame. The rotating plate is rotatably connected to the surface of the support rod. The push rod is fixedly connected to the sides of the two clamping plates away from each other. The top rod is slidably connected to the inner wall of the protective frame. The sliding plate is fixedly connected to the surface of the top rod. The elastic telescopic rod is fixedly connected to the side of the sliding plate away from the top rod. The positioning plate is fixedly connected to the end of the elastic telescopic rod away from the sliding plate. A return spring is sleeved on the surface of the top rod, and the return spring is located between the sliding plate and the protective frame. The end of the top rod away from the sliding plate contacts the rotating plate. The end of the push rod away from the clamping plate contacts the rotating plate. The positioning mechanism further includes an inclined rod, a fixed rod, an outer seal, and an inner seal. The inclined rod is fixedly connected to the side of the sliding plate close to the top rod. The fixed rod is fixedly connected to the side of the sliding plate close to the positioning plate. The outer seal is fixedly connected to the end of the fixed rod away from the sliding plate. The inner seal is slidably connected to the inner wall of the outer seal through a spring. The circumferential surface of the outer seal after movement contacts the inner wall of the positioning plate. The bottoms of the sliding plate and the positioning plate contact the transfer table. When the transfer table drives the motor housing to move under the welder or the spraying machine, the motor will rotate forward and backward reciprocally and drive the clamping plates to move reciprocally. However, the reciprocating movement of the clamping plates at this time will not contact the motor housing. At this time, the movement of the clamping plates will push the push rod to move. The push rod drives the rotating plate to rotate. The rotating plate drives the top rod to move. The top rod pushes the sliding plate to move. The sliding plate drives the positioning plate to move through the elastic telescopic rod. At this time, the two positioning plates gather and separate reciprocally, so as to position and align the motor housing on the top of the transfer table, ensure that the motor housing is directly below the welder and the spraying machine, and improve the accuracy of welding and spraying. When the two positioning plates gather and contact the motor housing, the positioning plate will be pushed by the motor housing to reversely compress the elastic telescopic rod. At this time, the displacement distance of the positioning plate just makes the inner seal on the surface of the fixed rod on the sliding plate contact the motor housing, so that the inner seal contacts the motor housing and leaves an imprint, indicating that the size of the motor housing is just right. If the size of the motor housing is too large, it will cause the inner seal to continue to be pushed after contacting the motor housing, resulting in the inner seal compressing the spring and retracting into the outer seal, causing the outer seal to also contact the motor housing, resulting in two imprints on the surface of the motor housing. If the size of the motor housing is too small, there will be no imprint on the surface of the motor housing. Therefore, the qualification of the motor housing can be judged by the imprint later, and it can be known whether the housing size is too large or too small, which is convenient for subsequent rework and recycling operations.

[0007] Preferably, the collection mechanism includes a collection box, a pulley, a brush, and a connecting rod. The collection box is fixedly connected to the inner wall of the protective frame. The pulley is rotatably connected to the inner wall of the protective frame. The connecting rod is fixedly connected to the axis of the pulley. The brush is fixedly connected to the circumferential surface of the connecting rod. The side of the brush away from the connecting rod contacts the conveyor belt on the surface of the transfer table. The circumferential surface of the pulley contacts the conveyor roller on the transfer table. The collection mechanism further includes a pressure rod, a connecting plate, and a pressing block. The pressure rod is slidably connected to the inner wall of the protective frame. The connecting plate is fixedly connected to the inner wall of the protective frame. The pressing block is fixedly connected to the surface of the pressure rod. The top inclined surface of the pressure rod contacts the end of the inclined rod away from the sliding plate. The surface of the connecting plate is slidably connected to the inner wall of the pressure rod, and an elastic member is provided between the top of the connecting plate and the inner wall of the pressure rod. When the conveyor roller in the transfer table rotates, it drives the pulley in contact with it to rotate. The pulley drives the connecting rod to rotate, and the connecting rod drives the brush to rotate. The brush will brush off the impurities and dust on the transfer table, causing the impurities and dust to enter the collection box for collection, preventing debris from adhering to the transfer table, and thus affecting the subsequent placement and processing of the motor housing. When the sliding plate moves, it drives the inclined rod to move. The inclined rod pushes the pressure rod downward through the inclined surface. The pressure rod drives the pressing block downward. The pressing block will impact the conveyor belt on the transfer table, causing the conveyor belt to arch and further shake off the debris and dust adhering to the surface, further improving the cleaning effect of the transfer table surface. When the pressure rod moves downward, it compresses the elastic member together with the connecting plate on the inner wall of the protective frame, facilitating the subsequent reset of the pressure rod.

[0008] Adopting the above technical solutions, the present invention can bring the following beneficial effects:

[0009] 1. For this servo motor housing polishing equipment, through the coordinated operation among the protective frame, transfer table, welding machine, polishing machine, spraying machine, motor, bidirectional screw, guide rod, moving plate, clamping plate, fixing plate, sponge block, transmission plate, roller, and brush plate, the integration of welding, polishing, cleaning, and spraying of the motor housing can be achieved, eliminating the need for multiple separate working procedures, improving work efficiency. At the same time, the motor housing on the transfer table can be clamped to prevent the motor housing from shaking during the grinding and polishing process, thereby affecting its grinding and polishing quality. When the clamping plate moves, it drives the transmission plate to move. The transmission plate drives the roller to move. The roller moves on the surface of the fixing plate and rotates itself while moving through friction. The roller drives the brush plate to rotate. The rotating brush plate knocks off the debris and dust adhering to the bottom of the sponge block, preventing excessive accumulation of debris after long-term use of the sponge block and thus affecting the subsequent cleaning effect after polishing the motor housing.

[0010] 2. The servo motor housing polishing equipment can position and align the motor housing on the top of the transfer table through the cooperation of the support rod, rotating plate, push rod, ejector rod, sliding plate, elastic telescopic rod, positioning plate, inclined rod, fixed rod, outer stamp, and inner stamp, ensuring that the motor housing is directly below the welding machine and spraying machine, improving the accuracy of welding and spraying. At the same time, it can detect whether the housing size of the motor housing is qualified and determine whether the housing size is too large or too small, facilitating subsequent rework and recycling operations.

[0011] 3. The servo motor housing polishing equipment, through the cooperation of the collection box, pulley, brush bristles, connecting rod, pressing rod, connecting plate, and pressing block, the brush bristles will brush off the impurities and dust on the transfer table, causing the impurities and dust to enter the collection box for collection, preventing debris from adhering to the transfer table and thus affecting the subsequent placement and processing of the motor housing. When the sliding plate moves, it will drive the inclined rod to move. The inclined rod pushes the pressing rod downward through the inclined plane, and the pressing rod drives the pressing block to move downward. The pressing block will hit the conveyor belt on the transfer table, causing the conveyor belt to arch and further shake off the debris and dust adhering to the surface, further improving the cleaning effect of the transfer table surface. When the pressing rod moves downward, it will compress the elastic member together with the connecting plate on the inner wall of the protective frame, facilitating the subsequent reset of the pressing rod.

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-7, an embodiment of the present invention is: a servo motor housing polishing device, including a protective frame 1. Inside the protective frame 1, a conveyor table 2 is installed. On the top of the protective frame 1, a welding machine 3, a polishing machine 4, and a spraying machine 5 are installed respectively. The welding machine 3, the polishing machine 4, and the spraying machine 5 are arranged in order from left to right. In the front of the welding machine 3, there are multiple welding heads, and the multiple welding heads are fixed and penetrate through the front of the protective frame 1. In the rear of the spraying machine 5, there are multiple nozzles, and the multiple nozzles are fixed and penetrate through the rear of the protective frame 1; Inside the protective frame 1, a clamping mechanism 6 is provided, a positioning mechanism 7 is provided, and a collection mechanism 8 is provided; The clamping mechanism 6 includes a motor 61, a bidirectional screw 62, a guide rod 63, a moving plate 64, a clamping plate 65, a fixing plate 66, a sponge block 67, a transmission plate 68, a roller 69, and a brush plate 610. The motor housing is placed into the device from the left side, and the motor housing moves to the right on the conveyor table 2. When the motor housing moves below the welding machine 3, the welding machine 3 will weld the motor housing. Then it continues to move below the polishing machine 4, and the polishing machine 4 will polish it. The polished motor housing will contact the sponge block 67, and the sponge block 67 will clean the polishing debris on the surface of the motor housing to prevent subsequent debris from affecting the spraying of the motor housing. Then when the motor housing is transported below the spraying machine 5, the spraying machine 5 will spray the motor housing. Thus, the integration of welding, polishing, cleaning, and spraying of the motor housing can be achieved, without the need for multiple processes to work separately, improving work efficiency. The motor 61 is fixedly connected to the front of the protective frame 1, the bidirectional screw 62 is fixedly connected to the output end of the motor 61, the guide rod 63 is fixedly connected to the inner wall of the protective frame 1, the moving plate 64 is threadedly connected to the circumferential surface of the bidirectional screw 62, the clamping plate 65 is fixedly connected to the bottom of the moving plate 64, the fixing plate 66 is fixedly connected to the inner wall of the protective frame 1, the sponge block 67 is installed at the bottom of the fixing plate 66, the transmission plate 68 is fixedly connected to the top of the clamping plate 65, the roller 69 is rotatably connected to the right side of the transmission plate 68, and the brush plate 610 is fixedly connected to the axis of the roller 69;The circumferential surface of the bidirectional screw 62 is rotatably connected to the inner wall of the protective frame 1. The inner wall of the moving plate 64 is slidably connected to the circumferential surface of the guide rod 63. The bottom of the clamping plate 65 contacts the transfer table 2. When the transfer table 2 conveys the motor housing under the polishing machine 4, the transfer table 2 stops operating and the motor 61 starts. The motor 61 drives the bidirectional screw 62 to rotate. The bidirectional screw 62 drives the two moving plates 64 to converge on the surface of the guide rod 63. The moving plate 64 drives the clamping plate 65 to move and clamp the motor housing on the transfer table 2, preventing the motor housing from shaking during the grinding and polishing process, thereby affecting its grinding and polishing quality. When the clamping plate 65 moves, it will drive the transmission plate 68 to move. The transmission plate 68 drives the roller 69 to move. The roller 69 moves on the surface of the fixed plate 66 and rotates itself while moving through friction. The roller 69 drives the brush plate 610 to rotate. The brush plate 610 rotates to knock off the debris and dust adhered to the bottom of the sponge block 67, preventing the sponge block 67 from accumulating too much debris after long-term use, thereby affecting the subsequent cleaning effect after the motor housing is polished.

[0022] Working principle: The motor housing is placed into the device from the left side. The motor housing moves to the right on the transfer table 2. When the motor housing moves under the welder 3, the welder 3 will weld the motor housing. Then it continues to move under the polishing machine 4, and the polishing machine 4 will grind and polish it. The polished motor housing will contact the sponge block 67. The sponge block 67 will clean the polishing debris on the surface of the motor housing to prevent subsequent debris from affecting the spraying of the motor housing. Then when the motor housing is conveyed under the spraying machine 5, the spraying machine 5 will spray the motor housing. Thus, the integration of welding, polishing, cleaning and spraying of the motor housing can be realized, without multiple processes working separately, improving the work efficiency. At the same time, when the transfer table 2 conveys the motor housing under the polishing machine 4, the transfer table 2 stops operating and the motor 61 starts. The motor 61 drives the bidirectional screw 62 to rotate. The bidirectional screw 62 drives the two moving plates 64 to converge on the surface of the guide rod 63. The moving plate 64 drives the clamping plate 65 to move and clamp the motor housing on the transfer table 2, preventing the motor housing from shaking during the grinding and polishing process, thereby affecting its grinding and polishing quality. When the clamping plate 65 moves, it will drive the transmission plate 68 to move. The transmission plate 68 drives the roller 69 to move. The roller 69 moves on the surface of the fixed plate 66 and rotates itself while moving through friction. The roller 69 drives the brush plate 610 to rotate. The brush plate 610 rotates to knock off the debris and dust adhered to the bottom of the sponge block 67, preventing the sponge block 67 from accumulating too much debris after long-term use, thereby affecting the subsequent cleaning effect after the motor housing is polished.

[0023] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, the positioning mechanism 7 includes a support rod 71, a rotating plate 72, a push rod 73, a top rod 74, a sliding plate 75, an elastic telescopic rod 76 and a positioning plate 77. The support rod 71 is fixedly connected to the front and rear sides of the protective frame 1. The rotating plate 72 is rotatably connected to the surface of the support rod 71. The push rod 73 is fixedly connected to the sides of the two clamping plates 65 away from each other. The top rod 74 is slidably connected to the inner wall of the protective frame 1. The sliding plate 75 is fixedly connected to the surface of the top rod 74. The elastic telescopic rod 76 is fixedly connected to the side of the sliding plate 75 away from the top rod 74. The positioning plate 77 is fixedly connected to the end of the elastic telescopic rod 76 away from the sliding plate 75. A return spring is sleeved on the surface of the top rod 74, and the return spring is located between the sliding plate 75 and the protective frame 1. The end of the top rod 74 away from the sliding plate 75 contacts the rotating plate 72. The end of the push rod 73 away from the clamping plate 65 contacts the rotating plate 72. When the transfer table 2 drives the motor housing to move under the welding machine 3 or the spraying machine 5, the motor 61 will rotate forward and backward reciprocally and drive the clamping plate 65 to move reciprocally. However, the reciprocating movement of the clamping plate 65 at this time will not contact the motor housing. At this time, the movement of the clamping plate 65 will push the push rod 73 to move. The push rod 73 drives the rotating plate 72 to rotate. The rotating plate 72 drives the top rod 74 to move. The top rod 74 pushes the sliding plate 75 to move. The sliding plate 75 drives the positioning plate 77 to move through the elastic telescopic rod 76. At this time, the two positioning plates 77 gather and separate reciprocally, so as to position and straighten the motor housing on the top of the transfer table 2, ensure that the motor housing is directly below the welding machine 3 and the spraying machine 5, and improve the accuracy of welding and spraying. The positioning mechanism 7 further includes an inclined rod 78, a fixed rod 79, an outer seal 710 and an inner seal 711. The inclined rod 78 is fixedly connected to the side of the sliding plate 75 close to the top rod 74. The fixed rod 79 is fixedly connected to the side of the sliding plate 75 close to the positioning plate 77. The outer seal 710 is fixedly connected to the end of the fixed rod 79 away from the sliding plate 75. The inner seal 711 is slidably connected to the inner wall of the outer seal 710 through a spring. The circumferential surface of the outer seal 710 after moving contacts the inner wall of the positioning plate 77. The bottoms of the sliding plate 75 and the positioning plate 77 contact the transfer table 2. When the two positioning plates 77 gather and contact the motor housing, the positioning plate 77 will be pushed by the motor housing to reversely compress the elastic telescopic rod 76. At this time, the displacement distance of the positioning plate 77 just makes the inner seal 711 on the surface of the fixed rod 79 on the sliding plate 75 contact the motor housing, so that the inner seal 711 contacts the motor housing and leaves an imprint, indicating that the size of the motor housing is just right. If the size of the motor housing is too large, it will cause the inner seal 711 to continue to be pushed after contacting the motor housing, resulting in the inner seal 711 compressing the spring and retracting into the outer seal 710, so that the outer seal 710 also contacts the motor housing, resulting in two imprints on the surface of the motor housing. If the size of the motor housing is too small, there will be no imprint on the surface of the motor housing. Therefore, the subsequent imprints can be used to judge whether the outer shell of the motor housing is qualified, and to know whether the outer shell size is too large or too small, which is convenient for subsequent rework and recycling operations.

[0024] The collecting mechanism 8 includes a collecting box 81, a pulley 82, bristles 83 and a connecting rod 84. The collecting box 81 is fixedly connected to the inner wall of the protective frame 1. The pulley 82 is rotatably connected to the inner wall of the protective frame 1. The connecting rod 84 is fixedly connected to the axis of the pulley 82. The bristles 83 are fixedly connected to the circumferential surface of the connecting rod 84. The side of the bristles 83 away from the connecting rod 84 contacts the conveyor belt on the surface of the conveyor table 2. The circumferential surface of the pulley 82 contacts the conveyor roller on the conveyor table 2. When the conveyor roller in the conveyor table 2 rotates, it will drive the pulley 82 in contact with it to rotate. The pulley 82 drives the connecting rod 84 to rotate. The connecting rod 84 drives the bristles 83 to rotate. The bristles 83 will brush off the impurities and dust on the conveyor table 2, so that the impurities and dust enter the collecting box 81 to be collected, preventing debris from adhering to the conveyor table 2 and thus affecting the subsequent placement and processing of the motor housing. The collecting mechanism 8 further includes a pressure rod 85, a connecting plate 86 and a pressing block 87. The pressure rod 85 is slidably connected to the inner wall of the protective frame 1. The connecting plate 86 is fixedly connected to the inner wall of the protective frame 1. The pressing block 87 is fixedly connected to the surface of the pressure rod 85. The top inclined surface of the pressure rod 85 contacts the end of the inclined rod 78 away from the sliding plate 75. The surface of the connecting plate 86 is slidably connected to the inner wall of the pressure rod 85, and an elastic member is provided between the top of the connecting plate 86 and the inner wall of the pressure rod 85. When the sliding plate 75 moves, it will drive the inclined rod 78 to move. The inclined rod 78 pushes the pressure rod 85 to move down through the inclined surface. The pressure rod 85 drives the pressing block 87 to move down. The pressing block 87 will hit the conveyor belt on the conveyor table 2, causing the conveyor belt to arch and further shake off the debris and dust adhering to the surface, further improving the cleaning effect of the surface of the conveyor table 2. When the pressure rod 85 moves down, it will compress the elastic member together with the connecting plate 86 on the inner wall of the protective frame 1, facilitating the subsequent reset of the pressure rod 85.

[0025] Working principle: When the transfer table 2 drives the motor housing to move under the welder 3 or the spraying machine 5, the motor 61 will rotate reciprocally in both forward and reverse directions and drive the clamping plate 65 to move reciprocally. However, the reciprocating movement of the clamping plate 65 at this time will not contact the motor housing. At this time, the movement of the clamping plate 65 will push the push rod 73 to move. The push rod 73 drives the rotating plate 72 to rotate. The rotating plate 72 drives the ejector rod 74 to move. The ejector rod 74 pushes the sliding plate 75 to move. The sliding plate 75 drives the positioning plate 77 to move through the elastic telescopic rod 76. At this time, the two positioning plates 77 reciprocally gather and separate, so as to position and align the motor housing on the top of the transfer table 2, ensuring that the motor housing is directly below the welder 3 and the spraying machine 5, improving the accuracy of welding and spraying. When the two positioning plates 77 gather and contact the motor housing, the positioning plate 77 will be pushed by the motor housing to reversely compress the elastic telescopic rod 76. At this time, the displacement distance of the positioning plate 77 just makes the inner seal 711 on the surface of the fixing rod 79 on the sliding plate 75 contact the motor housing, so that the inner seal 711 contacts the motor housing and leaves an imprint, indicating that the size of the motor housing is just right. If the size of the motor housing is too large, it will cause the inner seal 711 to continue to be pushed after contacting the motor housing, resulting in the inner seal 711 compressing the spring and retracting into the outer seal 710, so that the outer seal 710 also contacts the motor housing, resulting in two imprints on the surface of the motor housing. If the size of the motor housing is too small, there will be no imprint on the surface of the motor housing. Therefore, the qualification of the motor housing can be judged by the imprint later, and it can be known whether the housing size is too large or too small, which is convenient for subsequent rework and recycling operations.

[0026] When the conveyor roller in the transfer table 2 rotates, it will drive the pulley 82 in contact with it to rotate. The pulley 82 drives the connecting rod 84 to rotate. The connecting rod 84 drives the brush 83 to rotate. The brush 83 will brush off the impurities and dust on the transfer table 2, so that the impurities and dust enter the collection box 81 to be collected, preventing debris from adhering to the transfer table 2 and thus affecting the subsequent placement and processing of the motor housing. When the sliding plate 75 moves, it will drive the inclined rod 78 to move. The inclined rod 78 pushes the pressure rod 85 to move downward through the inclined plane. The pressure rod 85 drives the pressing block 87 to move downward. The pressing block 87 will impact the conveyor belt on the transfer table 2, causing the conveyor belt to arch and further shake off the debris and dust adhering to the surface, further improving the cleaning effect of the surface of the transfer table 2. When the pressure rod 85 moves downward, it will compress the elastic member together with the connecting plate 86 on the inner wall of the protective frame 1, facilitating the subsequent reset of the pressure rod 85.
