Description

Technical Field

[0001] The invention belongs to the technical field of motor assembly, and in particular relates to an automatic assembly device for a motor housing and a magnetic shoe. Background Art

[0002] A motor is an electromagnetic device that converts electrical energy into mechanical energy. It is mainly divided into electric motors and generators. Electric motors are devices that convert electrical energy into mechanical energy, while generators convert mechanical energy into electrical energy. Electric motors generate a rotating magnetic field through energized coils, which acts on the rotor to form a magneto-electrodynamic rotational torque, thereby achieving energy conversion.

[0003] In the assembly process of the motor, it is necessary to affix magnetic tiles around the inner wall of the shell. The main purpose of affixing magnetic tiles inside the motor shell is to generate a magnetic field to drive the motor to run. The magnetic tiles help the motor to achieve energy conversion and transmission by generating a magnetic field, thereby driving the motor to work normally.

[0004] In addition, the magnetic tiles have the following functions: the magnetic tiles can help reduce wear and friction inside the motor and extend the service life of the motor; and through the magnetic field of the magnetic tiles, the speed and direction of the motor can be controlled more accurately, improving the operating efficiency and control accuracy of the motor.

[0005] In the existing motor assembly process, the assembly of the magnetic tile and the motor housing still needs to be completed manually by the operator. Since the motor housing is small and the operating space inside is limited, the operator cannot accurately fit the magnetic tile to the inner wall of the motor housing. The fitting position is prone to deviation, which affects the qualified rate of the finished product. In addition, the manual mounting efficiency of the operator is low and cannot meet the production needs of the market. Summary of the invention

[0019] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] like Figure 1 As shown, it is a structural schematic diagram of the automatic assembly equipment of the motor housing and magnetic tiles of the present invention, which is usually used in the field of motor assembly and is used to automatically stick the magnetic tiles to the inner wall of the motor housing. The assembly equipment includes a base, a conveying structure 1, an upper housing structure 2, an upper magnetic tile structure 3, a transfer structure 4 and a test structure 5. The base is fixed to the workshop floor by screw fastening, and the conveying structure 1, the upper housing structure 2, the upper magnetic tile structure 3, the transfer structure 4 and the test structure 5 are fixed on the top of the base in sequence, and work in coordination with each other to stick the magnetic tiles to the inner wall of the motor housing.

[0021] The upper shell structure 2 is used to clamp the empty motor shell and place it on the base 101; the conveying structure 1 conveys the base 101 carrying the empty shell to the upper magnetic tile structure 3, and the upper magnetic tile structure 3 transfers the four magnetic tiles to the base 101, and sticks the magnetic tile ring to the inner wall of the casing, thereby completing the assembly of the magnetic tiles and the motor shell.

[0022] There are two groups of transfer structures 4, one of which is used to clamp the motor housing with magnetic tiles pasted on it and transfer it to an oven for baking to shorten the curing time and ensure the bonding effect; the other group of transfer structures 4 is used to remove the motor housing with magnetic tiles pasted on it after drying in the oven and place it at the test structure 5, which performs a pressure test on the magnetic tiles on the inner wall of the motor housing to ensure that the magnetic tiles are tightly adhered to the inner wall of the motor housing to avoid the magnetic tiles falling off during actual use.

[0023] like Figure 2-4 As shown, it is a schematic diagram of the structure of the conveying structure 1, which includes a conveyor belt assembly, a support seat, a guide plate 112, a guide groove 113, an arc portion 114, a fixing block 115, a patch mechanism and a lifting mechanism. The patch mechanism is used to carry a single magnetic tile, and the lifting mechanism cooperates with the patch mechanism. When the lifting mechanism rises, it will drive the patch mechanism to open outward synchronously, so that the magnetic tile ring is attached to the inner wall of the motor housing; when the lifting mechanism descends, the patch mechanism will be retracted inward, so that the transfer structure 4 can remove the motor housing with the magnetic tile attached.

[0024] The conveyor belt assembly is a conventional structure, which includes two rotating conveyor belts, which are wound around the same main roller and auxiliary roller. The main roller is driven by a driving motor to rotate, and the two conveyor belts are driven to rotate synchronously under the action of friction. The outer surface of the conveyor belt is provided with a convex column, and the base 101 is provided with a positioning hole that matches the convex column. The operators stand at both ends of the conveyor belt respectively. One of the operators inserts the base 101 on the convex column, and the base 101 moves forward with the conveyor belt to facilitate the loading and assembly of the magnetic tile and the motor housing; the other operator removes the assembled base 101 from the conveyor belt.

[0025] The sheath 102 is fixed on the top of the base 101. The interior of the sheath 102 is a hollow structure for protecting the internal structure (such as the push rod 109 and the return spring 111, etc.) to prevent external environmental factors such as dust and moisture from affecting the normal lifting of the push rod 109 and the return of the return spring 111.

[0026] The base plate 103 is fixed on the top of the sheath 102, and the fixing column 104 is fixed on the top of the base plate 103. During the step of attaching the magnetic tile, the magnetic tile is against the top of the fixing column 104, and the motor housing is inverted and inserted on the fixing column 104. The limiting groove 105 is vertically opened on the outer wall of the fixing column 104, and the limiting block 106 is fixed on the top of the base plate 103 by screw fastening and inserted into the limiting groove 105. The limiting block 106 is limited by the limiting groove 105, and then the inserted motor housing is positioned. Figure 2 As shown, the groove at the bottom of the motor housing is inserted into the limit block 106 .

[0027] The through hole 107 passes through the base plate 103 and the fixed column 104. When the ejector rod 109 and the ejector pin 110 of the subsequent lifting mechanism rise, they will pass through the through hole 107 and drive the patch mechanism to open outward synchronously to complete the ring-pasting work of the magnetic tile. The diameter of the ejector rod 109 is equal to the diameter of the through hole 107, which plays a guiding and positioning role for the lifting ejector rod 109, thereby improving the position accuracy of the magnetic tile after the ring-pasting and improving the qualified rate of the finished product.

[0028] like Figure 5 , 7 As shown, the guide plate 112 is arranged on the top of the fixed column 104. There are four guide plates 112, and the angle between every two guide plates 112 is 90°, so the angle between two adjacent magnetic tiles after laying is also 90°. The guide groove 113 is arranged between two adjacent guide plates 112 to guide the opening and closing movement of the patch mechanism, thereby improving the position accuracy of the magnetic tiles after the patch ring is attached.

[0029] The arc portion 114 is arranged outside the guide plate 112 , and the patch mechanism is retracted inwardly under the action of the elastic ring 122 , and the elastic ring 122 is retracted and pressed against the outside of the arc portion 14 , thereby preventing the patch mechanism from being overly retracted under the action of the arc portion 14 .

[0030] The fixing block 115 is fixed on the top of the four guide plates 112 by screw fastening. The fixing block 115 has three functions: first, it is used to fix the four guide plates 112 to prevent the deformation of the four guide plates 112, which will cause the guide groove 113 to change and affect the normal opening or closing of the patch mechanism; second, it is used to resist and limit the rising top rod 109 to prevent the top rod 109 from rising too much and causing the patch mechanism to open too much, so as to avoid damaging the motor housing and the magnetic tiles after the ring pasting; third, when the patch mechanism is opened outward, the fixing block 115 always presses against the upper surface of the plug plate 118 to ensure that the patch mechanism can only be opened outward horizontally or closed inward, so as to prevent the lifting mechanism from lifting the patch mechanism.

[0031] The patch structures are inserted into the guide grooves 113 between two adjacent guide plates 112, and the number of the patch structures is the same as the number of guide plates 112. Figure 5 , 6 As shown, the patch mechanism includes a patch plate 116, a first magnetic tile groove 117, an insert plate 118, a first avoidance groove 119, an inclined groove 120, a locking groove 121 and an elastic ring 122. The insert plate 118 is integrally connected to the inner side wall of the patch plate 116, and the insert plate 118 is inserted in the guide groove 113. The width of the insert plate 118 is equal to the width of the guide groove 113. When the insert plate 118 moves in the guide groove 113, it is prevented from shaking and affecting the ring-sticking effect of the magnetic tile.

[0032] The first magnetic tile groove 117 is provided on the outer side of the mounting plate 116 and matches the shape of the magnetic tile. During assembly, the magnetic tile is vertically inserted into the first magnetic tile groove 117 through the upper magnetic tile structure 3 and abuts against the top of the fixing column 104. Under the action of the friction between the magnetic tile and the side wall of the first magnetic tile groove 117, the magnetic tile is temporarily fixed in the first magnetic tile groove 117 and will not fall off.

[0033] The inclined slot 120 is obliquely opened at the bottom of the inner side of the plug plate 118 and cooperates with the ejector pin 110 of the jacking mechanism. When the ejector rod 109 drives the ejector pin 110 to rise, the ejector pin 110 drives the plug plate 118 to open outwards, and at the same time, the magnetic tile moves outwards and sticks to the inner wall of the motor housing.

[0034] The first avoidance groove 119 is formed at the top of the plug plate 118. Since the fixing block 115 is fixed at the top of the guide plate 112, the existence of the first avoidance groove 119 reduces the contact area between the plug plate 118 and the fixing block 115. When the ejector pin 110 drives the plug plate 118 to open outward, excessive friction between the plug plate 118 and the fixing block 115 is avoided to affect the ring contact of the magnetic tile.

[0035] The locking groove 121 is provided on the outer wall of the sticking plate 116, and the elastic ring 122 is sleeved in the locking groove 121. When the push rod 109 drives the push pin 110 to rise, the push pin 110 drives the plugging plate 118 to open outwards, and at the same time, the magnetic tile moves outwards and sticks to the inner wall of the motor housing. At this time, the plugging plate 118 opens outwards, and the elastic ring 122 is stretched and deformed; when the push rod 109 drives the push pin 110 to descend, there is a lack of support between the plugging plate 118 and the push pin 110. Under the resetting action of the elastic ring 122, the sticking plate 116 and the plugging plate 118 are synchronously retracted inwards back into the guide groove 113, which is convenient for the next magnetic tile assembly.

[0036] The locking groove 121 is configured to accommodate the elastic ring 122 , and while not affecting the opening or closing of the plug plate 118 and the sticking plate 116 , it also avoids the position of the magnetic tile, thereby avoiding affecting the insertion of the magnetic tile into the first magnetic tile groove 117 .

[0037] The lifting mechanism is arranged in the support seat and cooperates with the patch mechanism. When the lifting mechanism rises, it drives the patch mechanism to open outward synchronously, so that the magnetic tile ring is attached to the inner wall of the motor housing; when the lifting mechanism descends, the patch mechanism is retracted inward synchronously. Figure 8 As shown, the lifting mechanism includes a top plate 108, a top rod 109, a top pin 110 and a return spring 111. The cylinder body of the lifting cylinder is fixed on the machine base, and the piston rod of the lifting cylinder cooperates with the top plate 108 (the piston rod of the lifting cylinder is not fixedly connected to the top plate 108) to lift the top plate 108 (the lifting cylinder is not shown in the figure).

[0038] The top rod 109 is fixed on the top of the top plate 108 and passes through the through hole 107. The top pin 110 is integrally connected to the top of the top rod 109 and matches with the inclined groove 120 on the inner side of the plug plate 118. When the top plate 108 drives the top rod 109 to rise, the top pin 110 drives the plug plate 118 to open outwards, and at the same time, the magnetic tile moves outwards and sticks to the inner wall of the motor housing.

[0039] The return spring 111 is sleeved on the push rod 109 and is located between the top plate 108 and the base plate 103. When the top plate 108 drives the push rod 109 to rise, the return spring 111 is compressed. When the lifting cylinder is reset, the deformed return spring 111 assists the top plate 108 and the push rod 109 to reset.

[0040] The upper shell structure 2 is fixed on the top of the base, such as Figure 2 As shown, the empty motor housing is inserted into the base 101. Fig. 9 , 10As shown, the upper shell structure 2 includes an upper shell frame 201, a loading turntable 202, a shell plug 203, a clamping block 204, a transfer frame 205, a transfer table 206, a gantry 207, a first moving plate 208, a first lifting plate 209 and a finger cylinder 210. The upper shell frame 201 is fixed to the machine base by screw fastening, and the loading turntable 202 is connected to the upper shell frame 201 by a servo motor. The servo motor drives the loading turntable 202 to rotate, and then rotates the motor shell to the clamping position, which is convenient for the finger cylinder 210 to clamp and transfer the motor shell.

[0041] There are multiple housing plugs 203, which are arranged in a ring on the top of the loading turntable 202. The operator inserts the motor housing with glue on the inner wall into the housing plugs 203 in advance. The clamping block 204 is fixed on the outer wall of the housing plug 203 and matches with the groove on the motor housing. When the motor housing is inserted into the housing plug 203, the groove of the motor housing is clamped on the clamping block 204, and the motor housing is supported by the clamping block 204, so that the glue on the inner wall of the motor housing can be prevented from contacting with the housing plug 203, and the glue on the inner wall of the motor housing can be prevented from being wiped off.

[0042] The transfer frame 205 is fixed on the machine base and located on one side of the upper shell frame 201. The transfer table 206 is fixed on the top of the transfer frame 205. A CCD camera facing the transfer table 206 is installed on the top of the transfer frame 205 to detect whether the finger cylinder 210 correctly clamps the motor shell, thereby playing an anti-mistake role.

[0043] The gantry 207 is fixed on the machine base and mounted on the conveyor belt assembly. A slide rail and a slider that cooperate with each other are fixed on one side of the gantry 207, and the first movable plate 208 is fixed on the slider. A linear slide connected to the first movable plate 208 is fixed on the top of the gantry 207, and the first movable plate 208 is driven to move along the gantry 207 by the linear slide, thereby transferring the motor housing.

[0044] A lifting cylinder is fixed on the top of the first movable plate 208, and the piston rod of the lifting cylinder is connected to the first lifting plate 209, and the lifting cylinder drives the first lifting plate 209 to perform lifting motion. In order to improve the stability of the lifting motion of the first lifting plate 209, a sliding rail and a sliding block that cooperate with each other are also arranged between the first lifting plate 209 and the first movable plate 208.

[0045] The finger cylinder 210 is fixed at the bottom of the first lifting plate 209 and is used to clamp the motor housing and transfer it. Two first moving plates 208 are arranged on one side of the gantry 207, and a push column is fixed between the two first moving plates 208, so when the linear slide drives one of the first moving plates 208 to move, the push column will push the other first moving plate 208 to move synchronously.

[0046] One of the finger cylinders 210 is used to clamp the motor housing on the loading turntable 202 and transfer it to the transfer table 206 of the transfer rack 205. At the same time, another finger cylinder 210 is used to clamp the motor housing on the transfer table 206 and transfer it to the first fixed column 104 of the conveying structure 1. Figure 2 As shown, the beat consistency is achieved.

[0047] like Fig.11 The figure shows a schematic diagram of the structure of the upper magnetic tile structure 3. The upper magnetic tile structure 3 is fixed on the machine base and is located on one side of the conveyor belt assembly. It is used to press the magnetic tile onto the patch mechanism of the conveying structure 1, and then the patch mechanism sticks the magnetic tile ring onto the inner wall of the motor housing. The upper magnetic tile structure 3 includes a pushing magnetic tile assembly 31, an upper magnetic tile assembly 32, a bearing assembly 33 and a bonding assembly 34, wherein the pushing magnetic tile assembly 31 is used to push the single magnetic tile forward, the bearing assembly 33 is used to carry the single magnetic tile pushed out by the pushing magnetic tile assembly 31, and the bonding assembly 34 is used to receive the single magnetic tile on the bearing assembly 33, and press the magnetic tile onto the patch mechanism of the conveying structure 1, and then the patch mechanism sticks the magnetic tile ring onto the inner wall of the motor housing.

[0048] like Fig.12 As shown, it is a positional relationship diagram of the pushing magnetic tile assembly 31 and the bearing assembly 33. The pushing magnetic tile assembly 31 is used to push the single magnetic tile forward, and the bearing assembly 33 is used to carry the single magnetic tile pushed out by the pushing magnetic tile assembly 31. The pushing magnetic tile assembly 31 includes a support frame 310, a support plate 311, a push groove 312, a side baffle 313, a second magnetic tile groove 314, a vertical plate 315, a first driving wheel 316, a first conveyor belt 317, a first upper clamping plate 318, a first lower clamping plate 319, a slide plate 3110, a push plate 3111, a cushion block 3112, a through groove 3113, a main baffle 3114 and an adapter 3115. The support frame 310 is welded from aluminum profiles and fixed to the base by screw fastening. The support frame 310 mainly plays the role of supporting and fixing.

[0049] The support plate 311 is fixed to the top of the support frame 310 by screw fastening, and the push groove 312 passes through the support plate 311 in the vertical direction, and the push groove 312 is parallel to the length direction of the support plate 311 (when the push plate 3111 moves in the push groove 312, the magnetic tile in the second magnetic tile groove 314 is pushed forward).

[0050] There are two side baffles 313, which are vertically fixed on the top of the support plate 311 and parallel to the length direction of the support plate 311. A second magnetic tile groove 314 is formed between the two side baffles 313, and the upper magnetic tile assembly 32 clamps the stacked magnetic tiles and places them in the second magnetic tile groove 314. When the push plate 3111 moves in the push groove 312, the magnetic tiles in the second magnetic tile groove 314 are pushed forward, and then the single magnetic tile is pushed onto the bearing assembly 33.

[0051] like Fig.13 As shown, the main baffle 3114 is fixed on one side of the two side baffles 313, and the adapter 3115 is integrally connected to the inner side of the main baffle 3114. The adapter 3115 is arc-shaped and matches the shape of the magnetic tile. When the push plate 3111 pushes the magnetic tile in the second magnetic tile groove 314 forward, the main baffle 3114 and the adapter 3115 limit the magnetic tile to prevent the push plate 3111 from pushing the magnetic tile too much, thereby affecting the transition of the frontmost magnetic tile.

[0052] like Fig.14 As shown, the through groove 3113 passes through the support plate 311 and is close to the main baffle plate 3114. The shape of the through groove 3113 matches the shape of the magnetic tile. When the push plate 3111 pushes the magnetic tile in the second magnetic tile groove 314 forward, until the front end of the magnetic tile is against the adapter 3115 of the main baffle plate 3114, the front end of the magnetic tile is just above the through groove 3113. The front end of the magnetic tile falls into the through groove 3113 under the action of gravity, and then falls on the supporting assembly 33 below, realizing the transfer of the single-piece magnetic tile.

[0053] Due to the mutual adhesion of two adjacent magnetic tiles, under the influence of friction, the frontmost magnetic tile may be attached to the second adjacent magnetic tile and cannot fall normally. Therefore, it is necessary to press the frontmost magnetic tile downward through the first pressure strip 332 of the supporting component 33 to ensure the smooth falling of the frontmost magnetic tile.

[0054] The vertical plate 315 is fixed vertically between the support frames 310 by welding. There are two first driving wheels 316 (i.e., a driving wheel and a driven wheel), which are rotatably mounted on the same side of the vertical plate 315 and are arranged at intervals. The first conveyor belt 317 is wound around the two first driving wheels 316. The servo motor is fixed on the other side of the vertical plate 315 and is connected to one of the first driving wheels 316, which is used to drive the first driving wheel 316 to rotate, and then drive the first conveyor belt 317 to rotate (in this embodiment, the first conveyor belt 317 does not rotate 360°, but moves back and forth between the two first driving wheels 316, that is, the upper transmission belt moves back and forth between the two first driving wheels 316, thereby driving the upper push plate 3111 to move).

[0055] The slide rail is fixed to the top of the vertical plate 315 by screw fastening, the slider is slidably installed on the slide rail, and the slide plate 3110 is fixed on the slider. By setting the slide rail and slider that cooperate with each other, the stability of the slide plate 3110 during reciprocating movement is improved to prevent the slide plate 3110 from tilting and affecting the pushing of the magnetic tile in the second magnetic tile groove 314.

[0056] The first upper clamp plate 318 is located at the top of the upper first conveyor belt 317, and the first lower clamp plate 319 is located at the bottom of the upper first conveyor belt 317, and the first upper clamp plate 318 and the first lower clamp plate 319 are fixed together, so as to clamp the upper first conveyor belt 317. When the upper first conveyor belt 317 moves, it will drive the first upper clamp plate 318 and the first lower clamp plate 319 to move back and forth synchronously.

[0057] The slide plate 3110 is fixed to the first upper clamping plate 318, and the push plate 3111 is fixed to the top of the slide plate 3110 and passes through the push groove 312 and is placed in the second magnetic tile groove 314. The push plate 3111 is driven by the first conveyor belt 317 to move in the push groove 312, thereby pushing the magnetic tiles in the second magnetic tile groove 314 to move forward.

[0058] The pad 3112 is fixed to the inner side of the push plate 3111, that is, the side of the push plate 3111 close to the magnetic tile. The pad 3112 is made of rubber and plays a buffering role when the magnetic tile is pushed forward to avoid leaving an indentation on the magnetic tile.

[0059] The bearing assembly 33 is used to bear the single magnetic tile pushed out by the magnetic tile pushing assembly 31, and the bearing assembly 33 comprises a first bearing frame 330, a fourth lifting plate 331, a first pressure strip 332, a fixing plate 333, a clamping claw cylinder 334, a bearing transition plate 335, a transition groove 336, a guide part 337, a side clamping plate 338, a stop bar 339 and a third moving plate 3310. Fig.13 As shown, the first carrier 330 is fixed on the top of the support frame 310 and is mounted above the side baffle 313 .

[0060] The lifting slide is fixed on one side of the first carrier 330, and the fourth lifting plate 331 is connected to the lifting slide, and the fourth lifting plate is driven to perform lifting motion by the lifting slide. The first pressure strip 332 is fixed on the bottom of the fourth lifting plate 331, and the thickness of the first pressure strip 332 is the same as the thickness of a magnetic tile, so that the frontmost magnetic tile is pushed into the through groove 3113, and then falls on the transition groove 336 below, to assist the frontmost magnetic tile to fall.

[0061] The moving cylinder is fixed at the bottom of the vertical plate 315, and is used to push the third moving plate 3310 to move, thereby transferring the fallen single magnetic tile. The slider is fixed to one side of the support frame 310 through the mounting plate, and the slide rail is slidably mounted on the slider. The third moving plate 3310 is fixed on the slide rail and connected to the piston rod of the moving cylinder. When the moving cylinder drives the third moving plate 3310 to move forward to transfer the single magnetic tile, the cooperation between the slider and the slide rail is relied on to ensure the stability of the movement of the third moving plate 3310, thereby improving the effect of magnetic tile mounting.

[0062] The fixed plate 333 is fixed on the top of the third movable plate 3310, and the load-bearing transition plate 335 is vertically fixed on the top of the fixed plate 333. Fig.15 As shown, the transition groove 336 is provided on one side of the load-bearing transition plate 335, and is used to receive the single magnetic tile dropped from the front end of the second magnetic tile groove 314. The guide portion 337 is obliquely arranged at the top of the transition groove 336, and the magnetic tile is guided by the guide portion 337 during the falling process, so as to ensure that the magnetic tile falls smoothly into the transition groove 336.

[0063] The clamping cylinder 334 is fixed on the top of the fixed plate 333, and the side clamping plate 338 is fixed on the clamping cylinder 334. The side clamping plate 338 is driven to move inward or outward synchronously by the clamping cylinder 334. The blocking bar 339 is integrally connected to the opposite side of the side clamping plate 338. When the magnetic tile falls into the transition groove 336, the clamping cylinder 334 drives the side clamping plate 338 to move inward, so that the blocking bar 339 moves inward to hold the magnetic tile in the transition groove 336, so as to prevent the magnetic tile from falling during the transfer process.

[0064] The upper magnetic tile assembly 32 is fixed on the top of the machine base. The upper magnetic tile assembly 32 is used to clamp the stacked magnetic tiles and transfer them to the second magnetic tile groove 314 of the push magnetic tile assembly 31. Figure 16-19 As shown, the upper magnetic tile assembly 32 includes a magnetic tile frame 320, a magnetic tile material slot 321, an upper magnetic tile frame 322, a second moving plate 323, a second driving wheel 324, a second conveyor belt 325, a second upper clamping plate 326, a second lower clamping plate 327, a second lifting plate 328, a second fixed column 329, a first carrier plate 3210, a first pressing groove 3211, a baffle 3212, a clamping groove 3213, a first clamping plate 3214, a second clamping plate 3215, a third lifting plate 3216 and a first pressing plate 3217. The magnetic tile frame 320 is fixed on the top of the base, and the magnetic tile material slots 321 are arranged at intervals on the top of the magnetic tile frame 320, and the magnetic tile material slots 321 are used to place stacked magnetic tiles. The depth of the magnetic tile slot 321 is smaller than the height of the magnetic tiles, so that the first clamping plate 3214 and the second clamping plate 3215 can clamp the stacked magnetic tiles in the magnetic tile slot 321 (the operator stacks the magnetic tiles in the magnetic tile slot 321 in advance).

[0065] The upper magnetic tile frame 322 is fixed on the base and mounted above the magnetic tile frame 320. The slide rail is fixed to the top of the upper magnetic tile frame 322 by screw fastening, and the slider is slidably mounted on the top of the slide rail. The second movable plate 323 is fixed to the top of the slider, and the slide rail and the slider that cooperate with each other are provided to improve the stability of the second movable plate 323 when moving.

[0066] There are two sets of second driving wheels 324, which are rotatably mounted on the inner side of the upper magnetic tile frame 322. The second conveyor belt 325 is wound around the second driving wheels 324. A motor is fixed on the outer side of the upper magnetic tile frame 322 to drive the second driving wheels 324 to rotate, thereby driving the second conveyor belt 325 to rotate. The second driving wheels 324 are connected through the same roller shaft, so the second conveyor belt 325 rotates synchronously.

[0067] The second upper clamp plate 326 is located above the upper second conveyor belt 325, and the second lower clamp plate 327 is located below the upper second conveyor belt 325, and the second upper clamp plate 326 and the second lower clamp plate 327 are fixed together by screwing, so as to clamp the upper second conveyor belt 325. When the upper second conveyor belt 325 moves, it will drive the second upper clamp plate 326 and the second lower clamp plate 327 to move back and forth synchronously.

[0068] The second movable plate 323 is fixed to the top of the second upper clamping plate 326. When the second upper clamping plate 326 moves, it drives the second movable plate 323 to move. The cylinder body of the main lifting cylinder is fixed to the top of the second movable plate 323. The piston rod of the main lifting cylinder passes through the second movable plate 323 and is connected to the second lifting plate 328. The second lifting plate 328 is driven to move up and down by the main lifting cylinder. The second fixed column 329 is fixed to the bottom of the second lifting plate 328. The first carrier plate 3210 is fixed to the bottom of the second fixed column 329. When the main lifting cylinder drives the second lifting plate 328 to descend, it will drive the first carrier plate 3210 to descend synchronously.

[0069] like Fig.18 As shown, there are two baffles 3212, which are fixed at intervals at the bottom of the first carrier plate 3210, and the clamping groove 3213 is formed between the two baffles 3212, which is used to accommodate the magnetic tiles stacked in the magnetic tile slot 321. The first clamping plate 3214 is fixed on one side of the clamping groove 3213, and the second clamping plate 3215 is arranged on the other side of the clamping groove 3213. A moving cylinder connected to the second clamping plate 3215 is fixed at the bottom of the first carrier plate 3210, which is used to drive the second clamping plate 3215 to move, and then clamp the magnetic tiles stacked in the magnetic tile slot 321 in the clamping groove 3213.

[0070] Two guide sleeves are embedded on the second movable plate 323, and a guide column is fixed on the top of the first carrier plate 3210, and the guide column passes through the guide sleeve. When the main lifting cylinder drives the first carrier plate 3210 to perform lifting movement, it will drive the guide column to rise and fall synchronously along the guide sleeve to improve the lifting stability of the first carrier plate 3210, thereby improving the accuracy of clamping the magnetic tiles.

[0071] The auxiliary lifting cylinder is fixed at the bottom of the second lifting plate 328, and the third lifting plate 3216 is connected to the auxiliary lifting cylinder, and the auxiliary lifting cylinder drives the third lifting plate 3216 to move up and down. The third lifting plate 3216 is also embedded with a guide sleeve, which is mounted on the guide column to improve the stability of the lifting movement of the third lifting plate 3216.

[0072] The first pressing plate 3217 is fixed at the bottom of the third lifting plate 3216, and the first pressing groove 3211 passes through the first carrier plate 3210 and cooperates with the first pressing plate 3217. When the first clamping plate 3214 and the second clamping plate 3215 clamp the stacked magnetic tiles in the clamping groove 3213, the first pressing plate 3217 descends through the first pressing groove 3211 and rests on the upper surface of the magnetic tile, thereby improving the reliability of clamping the magnetic tile and preventing the magnetic tile from being misaligned in the vertical position and falling off when clamping.

[0073] like Fig.11 As shown, in order to improve the efficiency of magnetic tile loading, two sets of magnetic tile pushing components 31, two sets of upper magnetic tile components 32 and two sets of bearing components 33 are arranged on the top of the machine base, while there is only one set of laminating components 34, which is located between the two sets of bearing components 33. Fig. 20 , 21 As shown, the laminating assembly 34 includes a laminating frame 340, a driving wheel 341, a driven wheel 342, a synchronous belt 343, a rotating column 344, a transfer sleeve 345, a transfer slot 346, a second avoidance slot 347, an adsorption hole 348, a pressing frame 349, a fifth lifting plate 3410, a second pressing plate 3411 and a second pressing slot 3412. The laminating frame 340 is movably arranged between the two groups of bearing assemblies 33 under the drive of the moving cylinder. When the magnetic tile needs to be pressed, the laminating frame 340 moves to the top of the base 101.

[0074] The driving wheel 341 and the driven wheel 342 are rotatably mounted on the top of the laminating frame 340, respectively. The synchronous belt 343 is wound around the driving wheel 341 and the driven wheel 342. When the motor drives the driving wheel 341 to rotate, the driven wheel 342 is driven to rotate under the action of the synchronous belt 343. In order to prevent the synchronous belt 343 from slipping during rotation, the outer circumferences of the driving wheel 341 and the driven wheel 342 are provided with convex teeth, and the inner circumference of the synchronous belt 343 is provided with tooth grooves that match the convex teeth.

[0075] The rotating column 344 is fixed on the driven wheel 342 and installed on the laminating frame 340 through a bearing. When the synchronous belt 343 drives the driven wheel 342 to rotate, the rotating column 344 will be driven to rotate synchronously. The transfer sleeve 345 is fixed on the bottom of the rotating column 344 and rotates synchronously with the rotating column 344. The transfer groove 346 is arranged on the outer side of the transfer sleeve 345 to receive the single-piece magnetic tile pushed in the transition groove 336.

[0076] The second avoidance groove 347 is opened on the side of the transfer sleeve 345 and is used to connect two adjacent transfer grooves 346. When the supporting transition plate 335 moves inward to transfer a single magnetic tile, the magnetic tile is held between the baffle bars 339. Therefore, the second avoidance groove 347 is used to accommodate the inwardly moved baffle bars 339, thereby ensuring that the magnetic tile is tightly attached to the transfer groove 346.

[0077] The adsorption holes 348 are provided on the side of the transfer sleeve 345 and are connected to the external air pump through an air pipe. When the magnetic tile is attached to the transfer slot 346, the air pump is started to adsorb the magnetic tile to the transfer slot 346 to prevent the magnetic tile from falling. When a set of opposite transfer slots 346 are attached with magnetic tiles, the driven wheel 342 drives the transfer sleeve 345 to rotate 90 degrees, so that the other two vacant transfer slots 346 are also attached with magnetic tiles.

[0078] The pressing frame 349 is fixed on the top of the laminating frame 340, the cylinder body of the lifting cylinder is fixed on the top of the pressing frame 349, the piston rod of the lifting cylinder passes through the pressing frame 349 and is connected to the fifth lifting plate 3410, and the fifth lifting plate 3410 is driven to move up and down by the lifting cylinder. A guide sleeve is embedded on the laminating frame 340, and a guide column passing through the guide sleeve is fixed to the bottom of the fifth lifting plate 3410.

[0079] The second pressing plate 3411 is fixed at the bottom of the guide column, and the second pressing groove 3412 passes through the second pressing plate 3411 and cooperates with the transfer sleeve 345. After the four sides of the transfer sleeve 345 are adsorbed with magnetic tiles, the lifting cylinder drives the fifth lifting plate 3410 and the second pressing plate 3411 to descend. At this time, the second pressing groove 3412 avoids the position of the transfer sleeve 345, and the second pressing plate 3411 presses the magnetic tiles around the transfer sleeve 345 downward into the patch mechanism of the conveying structure 1 (that is, the magnetic tiles around the transfer sleeve 345 are pressed downward into the first magnetic tile grooves 117 of the patch plate 116).

[0080] The manipulator is fixed on the machine base and arranged opposite to the upper magnetic tile structure 3, and is used to clamp the motor housing on the base 101, so that the upper magnetic tile structure 3 can press the magnetic tile into the patch mechanism of the conveying structure 1. After the magnetic tile is pressed, the manipulator puts the motor housing back on the base 101, and the lifting mechanism rises to drive the patch mechanism to open outward, so that the magnetic tile ring is attached to the inner wall of the motor housing.

[0081] The transfer structure 4 is fixed on the machine base and is used to flip the housing with the magnetic tile attached and transfer it to an oven on one side for baking to shorten the curing time and ensure the bonding effect. Flipping the housing has two functions: one is to make the opening of the housing face upward to ensure that the glue coating is fully in contact with the hot air in the oven to improve the drying and curing effect; the other is to facilitate the subsequent testing of the test structure 5.

[0082] There are two transfer structures 4, one of which is used to transfer the casing into the oven, and the other is used to transfer the casing out of the oven. Fig. 22 As shown, the transfer structure 4 includes a transfer frame 41, a fourth moving plate 42, a sixth lifting plate 43, a rotating plate 44 and a clamping cylinder 45. The transfer frame 41 is fixed on the top of the base, the fourth moving plate 42 is arranged on one side of the transfer frame 41 by means of a slide rail and a slider, and a moving cylinder connected to the fourth moving plate 42 is fixed on the top of the transfer frame 41, which is used to drive the fourth moving plate 42 to move, thereby transferring the motor housing.

[0083] The lifting slide is fixed on the fourth moving plate 42, and the sixth lifting plate 43 is connected to the lifting slide, and the lifting slide drives the sixth lifting plate 43 to do lifting motion. The rotating cylinder is fixed on the bottom of the sixth lifting plate 43, the rotating plate 44 is fixed on the rotating part of the rotating cylinder, and the clamping cylinder 45 is fixed on the rotating plate 44. The housing is clamped by the clamping cylinder 45 and turned 180 degrees under the drive of the rotating cylinder, so that the opening of the motor housing faces upward.

[0084] The test structure 5 is fixed on the machine base, and the transfer structure 4 clamps the dried motor housing and places it on the test structure 5. The test structure 5 performs thrust testing on the magnetic tiles on the inner wall of the motor housing to ensure that the magnetic tiles are firmly installed in the housing. Fig.23 As shown, the test structure 5 includes a pressing assembly and a pressure measuring assembly. The pressing assembly is used to support the motor housing to be tested. The pressure measuring assembly is mounted above the pressing assembly to apply thrust to the magnetic tiles on the inner wall of the motor housing.

[0085] like Fig.25 As shown, the pressing assembly includes a second carrier 501, a fixture cylinder 502, an angle plate 503, a push cylinder 504, a connecting block 505, a pressure rod 506, a pressure head 507, a housing slot 508, a push column 509 and a pressing spring 5010. The second carrier 501 is fixed to the motor assembly base by screw fastening or welding, the fixture cylinder 502 is fixed to the top of the second carrier 501, the housing slot 508 is opened at the top of the fixture cylinder 502, and the motor housing to be tested is inserted into the housing slot 508 of the fixture cylinder 502. And the opening end of the motor housing is set upward (that is, the opening end of the motor housing is set away from the second carrier 501), which is convenient for the pressure test assembly to perform thrust testing on the magnetic tile on the inner wall of the motor housing.

[0086] The angle plate 503 is fixed to one side of the second carrier frame 501 by screw fastening, and the cylinder body of the push cylinder 504 is fixed to the top of the angle plate 503. The push column 509 is connected to the piston rod of the push cylinder 504, and the push cylinder 504 drives the push column 509 to move, thereby pushing the pressure rod 506 to rotate, so as to press the motor housing inserted into the housing slot 508, and prevent the housing from shaking when applying thrust to the magnetic tile, thereby affecting the accuracy of the test result.

[0087] There are two connecting blocks 505, which are fixed to the side of the fixture tube 502 close to the angle plate 503 by screw fastening. A mounting groove is provided between the two connecting blocks 505. The pressure rod 506 is installed between the two connecting blocks 505 by a pivot and is located in the mounting groove. The pressing spring 5010 is fixed between the pressing rod 506 and the fixture tube 502. By providing the pressing spring 5010, the pressing rod 506 is pushed to rotate to press the housing inserted into the housing groove 508. The pressing head 507 is integrally connected to the side of the pressing rod 506 away from the second carrier 501, and is used to press the housing.

[0088] The pushing cylinder 504 drives the push column 509 to move forward until the push column 509 contacts the pressure rod 506, and continues to move forward so that the compression spring 5010 is compressed and deformed. At this time, the pressure rod 506 rotates counterclockwise, and the pressure rod 506 drives the pressure head 507 to move away from the top of the motor casing; the transfer structure 4 inserts the new motor casing into the casing groove 508, and the pushing cylinder 504 drives the push column 509 to reset. Under the resetting action of the compression spring 5010, it drives the pressure rod 506 to rotate clockwise, and the pressure head 507 is pressed on the upper surface of the casing. When the thrust is applied to the magnetic tile later, the casing is prevented from shaking, thereby affecting the accuracy of the test result (the push column 509 and the pressure rod 506 are not fixedly connected, and the pressing action of the pressure rod 506 is achieved by resetting the compression spring 5010).

[0089] The pressure measuring assembly is mounted above the pressing assembly and is used to apply thrust to the magnetic tile on the inner wall of the casing. Fig.24 As shown, the pressure test assembly includes a test frame 5011, a seventh lifting plate 5012, a third fixed column 5013, a second carrier plate 5014, a linear bearing 5015, a guide column 5016, an anti-slip plate 5017, a test transition plate 5018, a first spring 5019, a pressure sensor 5020, a contact head 5021, an anti-slip block 5022, a second pressure strip 5023, a spring slot 5024 and a second spring 5025.

[0090] The test frame 5011 is fixed to the base of the motor assembly by screw fastening, and is located on one side of the second support frame 501. The seventh lifting plate 5012 is slidably installed on one side of the test frame 5011 by the cooperation of the slide rail and the slider, and performs lifting movement driven by the lifting cylinder, thereby applying thrust to the magnetic shoe in the motor casing.

[0091] like Fig.24 As shown, the linear bearing 5015 is embedded in the seventh lifting plate 5012, the guide column 5016 passes through the linear bearing 5015, and the top of the guide column 5016 is fixed with an anti-drop plate 5017, and the bottom of the guide column 5016 is fixed with a test transition plate 5018. The diameter of the anti-drop plate 5017 is larger than the diameter of the guide column 5016, so as to prevent the guide column 5016 and the test transition plate 5018 from falling from the linear bearing 5015.

[0092] The first spring 5019 is sleeved on the guide column 5016, and the two sides of the first spring 5019 are respectively pressed between the linear bearing 5015 and the test transition plate 5018. The first spring 5019 is used to reset the test transition plate 5018 to ensure that there is enough clearance between the seventh lifting plate 5012 and the test transition plate 5018 to prepare for the next test. The pressure sensor 5020 is fixed to the bottom of the seventh lifting plate 5012, and the contact head 5021 is fixed to the top of the test transition plate 5018 and cooperates with the pressure sensor 5020.

[0093] The third fixing column 5013 is fixed to the bottom of the seventh lifting plate 5012, and the second carrier plate 5014 is fixed to the bottom of the third fixing column 5013. The test rod is inserted into the second carrier plate 5014, and the second spring 5025 is fixed between the test rod and the test transition plate 5018. When the test rod applies thrust to the magnetic tile in the motor housing, the compression deformation of the second spring 5025 plays a buffering role to avoid rigid extrusion and damage to the structure of the magnetic tile.

[0094] like Fig.24 , which is a schematic diagram of the structure of the test rod, the test rod includes an anti-slip block 5022, a second pressure strip 5023 and a spring groove 5024. The second pressure strip 5023 runs through the second carrier 5014, the anti-slip block 5022 is integrally connected to the top of the second pressure strip 5023, and the top projection area of ​​the anti-slip block 5022 is larger than the top projection area of ​​the second pressure strip 5023, and the second pressure strip 5023 is supported and limited to prevent the second pressure strip 5023 from falling from the second carrier 5014. The spring groove 5024 is provided at the top of the anti-slip block 5022, and the second spring 5025 is arranged in the spring groove 5024, and the second spring 5025 is limited when compressed.

[0095] Four test rods are provided in a ring, corresponding to the magnetic tiles in the motor housing one by one, and the second pressure strip 5023 is fan-shaped, and the arc center angle of the second pressure strip 5023 is equal to the arc center angle of the magnetic tile. When applying thrust to the magnetic tile, it is ensured that there is enough contact area with the surface of the magnetic tile, and the four test rods move downward synchronously, and the thrust applied to the magnetic tile on the inner side wall of the housing is consistent, thereby improving the accuracy of the test results.

[0096] During the test, the lifting cylinder drives the seventh lifting plate 5012 down until the second pressure strip 5023 rests against the upper surface of the magnetic tile, and the lifting cylinder continues to work. The second spring 5025 and the first spring 5019 are compressed and deformed until the contact head 5021 contacts the pressure sensor 5020. The pressure sensor 5020 can be used to determine the current thrust applied to the magnetic tile. At the same time, the buffering effect of the second spring 5025 can prevent rigid extrusion from damaging the magnetic tile.

[0097] After testing for a period of time, the magnetic tiles in the casing are photographed by a CCD camera to determine whether the position of the magnetic tiles on the inner wall of the casing changes under the action of the rated thrust, and then determine whether the current magnetic tiles are installed reliably.

[0098] The assembly process of the motor housing and magnetic shoe automatic assembly equipment of the present invention is as follows; First, the motor housing is clamped by the upper housing structure 2 and inserted into the first fixing column 104. Figure 2 As shown, the conveying structure 1 then drives the base 101 to move to the upper magnetic tile structure 3; At this time, the motor housing on the base 101 is first removed by the manipulator on the top of the base, and the upper magnetic tile assembly 32 clamps the stacked magnetic tiles into the second magnetic tile groove 314 of the push magnetic tile assembly 31, and the push plate 3111 pushes the magnetic tiles in the second magnetic tile groove 314 until the single magnetic tile passes through the through groove 3113 and falls into the transition groove 336 of the bearing assembly 33, and the bearing assembly 33 drives the single magnetic tile to move to the transfer groove 346 attached to the bonding assembly 34, and the second pressing plate 3411 descends to press the magnetic tile on the transfer groove 346 into the first magnetic tile groove 117 of the pasting plate 116, and then the manipulator puts the housing back on the base 101, and the lifting mechanism rises, driving the pasting mechanism to open outward synchronously, and the magnetic tile ring is attached to the inner wall of the motor housing; The conveying structure 1 drives the base 101 to move to the transfer structure 4, and the transfer structure 4 clamps the shell and turns it 180 degrees, and puts it into the oven for baking; The dried rear shell is taken down by another set of transfer structures 4 and placed in the fixture cylinder of the test structure 5, and the pressure test of the magnetic shoe is completed by the pressure measuring assembly.
