Description

Technical Field

[0001] The present invention relates to the field of drying of anti-oxidation paint surfaces of rotors, and particularly to a device for drying the anti-oxidation paint surfaces of rotors in the production of brushless motors. Background Art

[0002] During the production of existing brushless motors, usually the rotors of the brushless motors are first subjected to dip painting treatment, and then the paint adhering to the rotors is dried by a drying device, so as to form an anti-oxidation paint surface on the rotor surface, isolate moisture and oxygen in the air, slow down the oxidation process of the rotor, and extend the service life of the rotor; In the prior art, in order to evenly dry the paint surface of the rotor, a gripper with a rotating function is usually used to grip the rotor. However, there is a situation where paint accumulates at the part where the gripper contacts the rotor.

[0019] It also includes a blocking plate 12; a blocking plate 12 is fixedly connected to each connecting plate 3.

[0020] It also includes a pulley 13; two first chutes 103 are provided on the drying oven 1; two second chutes 104 are provided on the mounting frame 101, and each second chute 104 communicates with the corresponding first chute 103; two third chutes 105 are provided on the frame body 102, and each third chute 105 communicates with the corresponding first chute 103. A pulley 13 is bolted to each connecting plate 3, and the pulley 13 is slidably engaged with the first chute 103. The pulley 13, the first chute 103, the second chute 104 and the third chute 105 cooperate to make the connecting plate 3 and its connected parts stably pass through the frame body 102, the drying oven 1 and the mounting frame 101 from left to right in sequence.

[0021] The following description is based on Figure 1 a perspective reference, where the side where the label of the frame body 102 is located is the front, and the side where the label of the chain conveyor 2 is located is the left.

[0022] The following describes the rotor clamping operation, taking the clamping component to the left of the frame body 102 as an example; First, place the two clamping ends of the rotor between the upper and lower conveyor belts 10 in the front and rear respectively. At this time, the two clamping ends of the rotor are respectively located between the corresponding four limit members 11. Then, control the two clamping arms of the two electric clamps 4 to drive the corresponding first mounting plate 5 and its connected parts to move towards the clamping ends of the rotor. During this process, since the conveyor belt 10 is restricted by the rotor and cannot move forward, as the clamping arms of the electric clamp 4 drive the corresponding first mounting plate 5 and its connected parts to move towards the clamping ends of the corresponding rotor, the diameter of the middle part of the conveyor belt 10 will be compressed and become smaller, and form an arc shape similar to the clamping end of the rotor. When the middle part of the conveyor belt 10 is compressed, the left and right ends of the conveyor belt 10 will approach each other, and pull the corresponding two second mounting plates 6 and their connected parts to approach each other, and the first spring member 7 is compressed. At the same time, since the two clamping ends of the rotor are respectively located between the corresponding four limit members 11, after the two clamping arms of the two electric clamps 4 drive the corresponding first mounting plate 5 and its connected parts to move towards the clamping ends of the rotor, the two clamping ends of the rotor will be stably clamped by the corresponding two conveyor belts 10 in the state as shown in Figure 9 shown.

[0023] The following describes the drying operation of the rotor; After the two clamping ends of the rotor are clamped by the corresponding two conveyor belts 10 in the clamping member on the left side of the frame 102, taking the front-to-back view as the reference, control the chain conveyor 2 to drive the clamping member on the left side of the frame 102 to rotate intermittently in the clockwise direction, so that the clamping member on the left side of the frame 102 drives the rotor to pass through the frame 102, the drying oven 1, and the mounting frame 101 from left to right in sequence. During this process, when the clamping member on the left side of the frame 102 drives the rotor to move into the drying oven 1, dry the paint on the copper wire wound part of the rotor through the drying oven 1, so as to form an anti-oxidation paint surface on the copper wire wound part of the rotor. When drying, taking the front-to-back view as the reference, control the output shafts of the two upper servo motors 9 to drive the conveyor belts 10 to rotate clockwise through the corresponding rotating shaft rods 8, and at the same time, control the output shafts of the two lower servo motors 9 to drive the conveyor belts 10 to rotate counterclockwise through the corresponding rotating shaft rods 8, so that all the conveyor belts 10 jointly drive the rotor to rotate, so that the paint on the copper wire wound part of the rotor can be evenly dried.

[0024] The following describes the self-cleaning operation of the clamping member; When the clamping component on the left side of the frame 102 moves into the installation frame 101 driven by the chain conveyor 2, control the two clamping arms of the two electric grippers 4 to drive the corresponding mounting plate 5 and the parts connected thereto to continue moving towards the clamping end of the rotor, so that the left and right ends of the upper two conveyor belts 10 are in contact with the left and right ends of the corresponding lower conveyor belts 10. Then, taking the front-to-back view as a reference, control the output shafts of the upper two servo motors 9 to drive the conveyor belts 10 to rotate clockwise again through the corresponding rotating shaft rods 8. At the same time, control the output shafts of the lower two servo motors 9 to drive the conveyor belts 10 to rotate counterclockwise again through the corresponding rotating shaft rods 8, so that the upper two conveyor belts 10 and the corresponding lower conveyor belts 10 rub against each other, so as to mutually abrade the paint attached to each other between the upper two conveyor belts 10 and the corresponding lower conveyor belts 10. In this way, it avoids the problem in the prior art that after each clamping operation of the gripper, it is necessary to manually stop the machine to clean the paint accumulated on the gripper, increasing the workload of the workers and seriously affecting the production efficiency of the rotor.

[0025] It should be noted that during the process of the conveyor belt 10 rotating the rotor in the drying oven 1, the upper two conveyor belts 10 will not contact the corresponding lower conveyor belts 10. When the clamping component is in the drying oven 1, the upper two conveyor belts 10 and the corresponding lower conveyor belts 10 do not perform the paint removal operation, that is, the paint chips will not fall into the drying oven 1.

[0026] The following describes the cooperative operation of multiple clamping components; It should be noted in advance that as Figure 8 shown, there is a clamping component for clamping the rotor to be clamped on the left side of the frame 102, there is a clamping component for clamping the rotor to be dried in the frame 102, there is a clamping component for clamping the rotor being dried in the drying oven 1, there is a clamping component for clamping the dried rotor in the installation frame 101, and there is a clamping component for clamping the rotor to be removed on the right side of the installation frame 101; and the widths inside the frame 102, the frame 102 and the installation frame 101 are the same.

[0027] It should be noted that, since the distance between the baffle plates 12 on two adjacent clamping members is equal to the width of the drying oven 1, the baffle plates 12 on the clamping members located within the frame 102 will be at the connection between the drying oven 1 and the frame 102, and the baffle plates 12 on the clamping members within the drying oven 1 will be at the connection between the drying oven 1 and the mounting frame 101. Moreover, the baffle plates 12 on the clamping members within the frame 102 will contact the inner upper side, inner front side, and inner rear side of the left channel of the drying oven 1, and the baffle plates 12 on the clamping members within the drying oven 1 will contact the inner upper side, inner front side, and inner rear side of the right channel of the drying oven 1. Then, the baffle plates 12 on the clamping members within the frame 102 will block the left channel of the drying oven 1, and the baffle plates 12 on the clamping members within the drying oven 1 will block the right channel of the drying oven 1. In this way, by blocking the channels of the drying oven 1 with the baffle plates 12, the heat overflow within the drying oven 1 is reduced, achieving the purpose of reducing energy loss. And compared with setting an electric control baffle at the connection of the frame 102, the frame 102, and the mounting frame 101 to reduce the heat overflow within the drying oven 1, the present invention is achieved through the mutual cooperation of the baffle plates 12 on the clamping members, with reduced cost and convenient maintenance.

[0028] Embodiment 2 Based on Embodiment 1, as Figures 1 - 6 and Figure 8 shown, it further includes a suction pipe 211; two symmetrically arranged suction pipes 211 for sucking paint chips are connected and fixed to the mounting frame 101, and the suction pipe 211 is connected to an external paint chip recovery device.

[0029] It further includes an electric push rod 212, a plate top 213, a mounting strip 214, a folding plate 215, a clamping strip 216, an electric push rod 217, and a bottom plate 218; four electric push rods 212 distributed in a rectangle are bolted to the mounting frame 101; the telescopic parts of all the electric push rods 212 are jointly fixed to the plate top 213; four mounting strips 214 distributed in a rectangle are fixed to the plate top 213; each mounting strip 214 is fixed with a folding plate 215; each folding plate 215 is fixed with a clamping strip 216, and each clamping strip 216 is provided with an arc-shaped part 21601 matching the diameter of the rotor's to-be-clamped end, and the arc-shaped parts 21601 on the left and right adjacent clamping strips 216 are symmetrically arranged; each mounting strip 214 is fixed with two electric push rods 217, and the telescopic part of each electric push rod 217 is fixed to the corresponding clamping strip 216; each connecting plate 3 is fixed with two bottom plates 218 distributed in the front and rear, and each bottom plate 218 contacts the corresponding baffle plate 12, and the bottom plates 218 are all located directly above the chain of the chain conveyor 2.

[0030] It further includes a first pump 221, a long pipe 222, and a tee pipe 223; the folding plate 215 is provided as hollow, and a number of through holes are formed on the side of the folding plate 215 facing the side wall of the mounting frame 101; a first pump 221 is bolted to the top plate 213; the first pump 221 is connected and fixed to the long pipe 222; the long pipe 222 is connected and fixed to two tee pipes 223 distributed front and back, and each tee pipe 223 passes through the top plate 213 and is connected to the corresponding folding plate 215.

[0031] It further includes an adsorption cloth 231; two adsorption cloths 231 distributed front and back are connected to the mounting frame 101, and the adsorption cloth 231 is used for adsorbing paint chips.

[0032] It further includes sliding blocks 241 and second spring members 242; four sliding blocks 241 distributed in a rectangle are slidably connected to the front side and the rear side of the mounting frame 101, and each sliding block 241 is fixedly connected to the corresponding adsorption cloth 231; a second spring member 242 is fixedly connected between each sliding block 241 and the mounting frame 101, and the sliding blocks 241 and the second spring members 242 cooperate to self-clean the adsorption cloth 231.

[0033] It further includes an air duct 251; the air duct 251 is fixedly connected to the top plate 213, and the air duct 251 is connected to the long pipe 222 and is located between the four folding plates 215.

[0034] Considering that during the process of the upper two conveyor belts 10 rubbing off the paint attached to each other with the corresponding lower conveyor belts 10, since the rubbed-off paint chips are in a floating state within the mounting frame 101, therefore, some paint chips will successively enter the drying oven 1 through the space of the chain on the mounting frame 101 and the space of the chain on the drying oven 1, resulting in the contamination of the rotor being dried in the drying oven 1 and affecting the quality of the anti-oxidation paint surface formed on the rotor. At the same time, during the process of the clamping member within the mounting frame 101 moving to the position where the clamping member was originally on the right side of the mounting frame 101, the floating paint chips within the mounting frame 101 will disperse into the external air, and the paint chips floating into the external air will pose a hazard to the environment and human health. For example, it is easy for humans to inhale the paint chips and cause respiratory diseases. Therefore, a suction pipe 211 is added, and during the process of the upper two conveyor belts 10 rubbing off the paint attached to each other with the corresponding lower conveyor belts 10, the external paint chip recovery device is controlled to suck out the paint chips within the mounting frame 101 through the front and rear suction pipes 211, so as to prevent the paint chips from entering the drying oven 1 during the process of the upper two conveyor belts 10 rubbing off the paint attached to each other with the corresponding lower conveyor belts 10, resulting in the problem that the paint on the winding copper wire part of the rotor in the drying oven 1 is contaminated after contacting the paint chips, and at the same time, avoiding the problem that the paint chips within the mounting frame 101 will disperse into the external air during the process of the clamping member within the mounting frame 101 moving to the position where the clamping member was originally on the right side of the mounting frame 101.

[0035] Considering that during the process of removing paint chips in the installation frame 101 by the suction pipes 211 at the front and rear, the floating paint chips may float towards the copper wire winding part of the rotor and adhere to the anti-oxidation paint surface formed on the copper wire winding part of the rotor, resulting in subsequent manual cleaning and increasing the workload of the workers.

[0036] Therefore, an electric push rod 1 (212), a plate top (213), a mounting strip (214), a folding plate (215), a clamping strip (216), an electric push rod 2 (217) and a bottom plate (218) are additionally provided. The two clamping ends of the rotor in the mounting frame (101) are respectively directly below the corresponding left and right adjacent clamping strips (216). Before the upper two conveyor belts (10) and the corresponding lower conveyor belts (10) mutually abrade the paint adhered to each other, control the telescopic part of the electric push rod 1 (212) to drive the plate top (213) and its connected parts to move downward until the lower surface of the plate top (213) contacts the upper surface of the mounting frame (101), so that the two arc-shaped parts (21601) on the front side and the rear side are aligned with the clamping ends of the rotor in the corresponding mounting frame (101). Then, control the telescopic parts of all the electric push rods 2 (217) to push the corresponding clamping strips (216) to move towards the rotor in the mounting frame (101) and stretch the folding plate (215) until the two left clamping strips (216) contact the corresponding right clamping strips (216). At this time, the two clamping ends of the rotor in the mounting frame (101) will be clamped by the corresponding left and right adjacent arc-shaped parts (21601). At this time, when the lower surface of the plate top (213) contacts the upper surface of the mounting frame (101), the lower surface of the plate top (213) will contact the upper surface of the blocking plate (12) in the clamping component in the mounting frame (101). The left side surfaces of the two left mounting strips (214) will both contact the right side surface of the blocking plate (12) in the clamping component in the drying box (1). The right side surfaces of the two right mounting strips (214) will both contact the left side surface of the blocking plate (12) in the clamping component in the mounting frame (101). The lower surfaces of all the mounting strips (214), the folding plate (215) and the clamping strips (216) will all contact the upper surface of the bottom plate (218) in the corresponding clamping component in the mounting frame (101). The front side surface of the front bottom plate (218) in the clamping component in the mounting frame (101) contacts the inner front side of the mounting frame (101). The rear side surface of the rear bottom plate (218) in the clamping component in the mounting frame (101) contacts the inner rear side of the mounting frame (101). Therefore, when the two left clamping strips (216) contact the corresponding right clamping strips (216), the blocking plate (12) in the clamping component in the drying box (1), the blocking plate (12) in the clamping component in the mounting frame (101), the plate top (213), the mounting frame (101) and all the mounting strips (214), the folding plate (215), the clamping strips (216), the bottom plate (218) cooperate to form two closed spaces distributed front and rear. Each electric gripper (4) in the clamping component in the mounting frame (101) and its connected parts are all in the corresponding closed space. Then, during the process of the upper two conveyor belts (10) and the corresponding lower conveyor belts (10) mutually abrading the paint adhered to each other, the abraded paint chips will be in the corresponding closed space. In this way, it is avoided that during the process of the front and rear suction pipes (211) sucking out the paint chips in the mounting frame (101), the floating paint chips will float towards the copper wire winding part of the rotor and adhere to the anti-oxidation paint surface formed on the copper wire winding part of the rotor, thereby causing subsequent manual cleaning and increasing the workload of the workers.

[0037] After the upper two conveyor belts 10 and the corresponding lower conveyor belts 10 have ground off the paint attached to each other, first control the telescopic parts of all the second electric push rods 217 to drive the corresponding clamping strips 216 to move away from the rotor in the mounting frame 101 and return to the initial position, and then control the telescopic parts of the first electric push rods 212 to drive the plate top 213 and the parts connected thereto to move upward and return to the initial position.

[0038] Furthermore, by adding a first pump 221, a long pipe 222 and a three-way pipe 223, during the process of the suction pipe 211 sucking out the paint chips in the mounting frame 101, control the first pump 221 to convey the outside air to the inside of the folding plate 215 through the long pipe 222 and the three-way pipe 223 in sequence, so that the outside air blows the paint chips to move towards the suction pipe 211 through the air holes formed in the folding plate 215, and the paint chips can be better sucked out by the suction pipe 211.

[0039] Considering that during the process of the outside air blowing the paint chips towards the suction pipe 211, the outside air will rebound after contacting the inner wall of the mounting frame 101 and form a turbulent flow in the enclosed space, resulting in some paint chips being difficult to be sucked out by the suction pipe 211. Furthermore, during the process of the clamping component in the subsequent mounting frame 101 moving to the position where the clamping component on the right side of the original mounting frame 101 is located, the un-sucked paint chips in the enclosed space will overflow into the outside air.

[0040] Therefore, a wet adsorption cloth 231 is added. During the process of the outside air blowing the paint chips towards the suction pipe 211, since the outside air blown out from the folding plate 215 is directly facing the adsorption cloth 231, before the outside air contacts the inner wall of the mounting frame 101, the paint chips in the outside air will be adsorbed on the adsorption cloth 231, so that there are no paint chips in the outside air that rebounds after contacting the inner wall of the mounting frame 101, thus avoiding the problem that the outside air rebounds after contacting the inner wall of the mounting frame 101 and forms a turbulent flow in the enclosed space, resulting in some paint chips being difficult to be sucked out by the suction pipe 211.

[0041] Further, by adding a sliding block 241 and a second spring member 242, and during the process that the external air blows the paint chips towards the suction pipe 211, since the external air blown out from the folding plate 215 is directly facing the adsorption cloth 231, the adsorption cloth 231 and the sliding block 241 will move away from the folding plate 215 under the action of the wind pressure and compress the second spring member 242. After the paint on the conveyor belt 10 is removed, since the first pump 221 no longer conveys the external air into the closed space, the second spring member 242 will push the adsorption cloth 231 to return to its initial position through the sliding block 241. During this process, the adsorption cloth 231 will vibrate, and the paint chips adsorbed on the adsorption cloth 231 will fall into the suction pipe 211 under the vibration, so that the self-cleaning of the adsorption cloth 231 is realized, avoiding the problem that when the adsorption cloth 231 adsorbs a large amount of paint chips, it will be difficult for the adsorption cloth 231 to normally adsorb the paint chips.

[0042] Further, during the process that the first pump 221 conveys the external air into the closed space, part of the external air will sequentially pass through the long pipe 222 and the air duct 251 and blow towards the winding copper wire part of the rotor in the mounting frame 101 to accelerate the cooling time of the anti-oxidation paint surface on the winding copper wire part of the rotor in the mounting frame 101.

[0043] Embodiment 3 On the basis of Embodiment 2, as Figure 7 and Figure 8 shown, it further includes a second pump 311, a first air pipe 312, a first conveying pipe 313, a second conveying pipe 314 and a second air pipe 315; the drying oven 1 is bolted with the second pump 311; the second pump 311 is communicated and fixedly connected with the first air pipe 312, and the first air pipe 312 is communicated with the mounting frame 101, and the first air pipe 312 is located between the four folding plates 215; the first air pipe 312 is communicated with the first conveying pipe 313, and the first conveying pipe 313 is communicated with the second pump 311; the frame body 102 is communicated and fixedly connected with the second air pipe 315; the second air pipe 315 is communicated with the second conveying pipe 314, and the second conveying pipe 314 is communicated with the second pump 311.

[0044] It should be noted that during the process of the front and rear suction pipes 211 sucking out the paint chips in the installation frame 101, the control pump two 311 sequentially sucks the air in the installation frame 101 into its interior through the first conveying pipe 313 and the first air pipe 312 (it should be noted that the part where the first air pipe 312 communicates with the installation frame 101 is between two sealed spaces (folding plates 215), that is, the first air pipe 312 does not suck the paint chips in the sealed space), and then sequentially conveys the sucked air to the frame 102 through the pump two 311, the second conveying pipe 314 and the second air pipe 315, so that the air conveyed to the frame 102 blows onto the rotor to be dried in the frame 102. At this time, since a large amount of hot air in the drying box 1 overflows into the installation frame 101 during the process of the clamping component in the drying box 1 moving to the position where the clamping component in the original installation frame 101 is located, therefore, the air conveyed to the frame 102 is hot air. Then, by transferring the air in the installation frame 101 to the frame 102 and making the air blow onto the winding copper wire part of the rotor in the frame 102, the winding copper wire part of the rotor in the frame 102 can be preheated to accelerate the overall drying efficiency of the paint on the winding copper wire part of the rotor.

[0045] The above embodiments are only preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made based on the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
