Description

Technical Field

[0001] The present invention relates to the field of motor manufacturing, and in particular to a device for gluing and assembling magnetic tiles and housings. Background Art

[0002] Heat-curing glue, such as epoxy resin structural glue, hot melt glue, acrylic structural glue and polyurethane glue, is often used to bond the magnetic tiles of the motor stator. These glues usually have excellent bonding strength, high temperature resistance and good environmental adaptability to ensure that the magnetic tiles will not loosen or fall off during the operation of the motor.

[0003] The structure of conventional magnetic tile and stator assembly can refer to the magnetic tile shell assembly equipment disclosed in the Chinese patent publication number CN116317387A. The equipment includes a material storage structure, a gluing device, a ferromagnetic device and a top magnetic device. The ferromagnetic device includes a rotating component and a magnetic mold. The rotating component will drive the magnetic mold and the shell to rotate. The top magnetic device includes a transfer component, a top magnetic component and a top magnetic mold. The transfer component is arranged between the gluing device and the ferromagnetic device. The transfer component transfers the glued magnetic tile to one side of the ferromagnetic device. The top magnetic mold extends into the interior of the shell. The outside of the top magnetic mold is an arc-shaped guide surface. The top magnetic component pushes the magnetic tile located in the transfer component into the interior of the shell. The magnetic tile is guided into the interior of the shell by the arc-shaped guide surface and directly attached to the inner wall of the shell.

[0004] The process of the top magnetic assembly pushing the magnetic tile into the shell is a linear motion, and the magnetic tile needs to fit the inside of the shell. There will inevitably be glue scraping. If the amount of glue applied is too little, although the degree of glue scraping can be reduced, the problem of local non-adhesion will further occur. Not only will there be a little glue scraping on the outside of the magnetic tile and glue overflow, but the local lack of glue will also lead to poor adhesion stability. In subsequent use, the magnetic tile will loosen and the glue overflow will fall off, interfering with the operation of the rotor, thus seriously affecting the service life of the motor; if the amount of glue applied is sufficient, the degree of glue scraping will be aggravated, and there will be a problem of thin glue at the bottom and thick glue at the top during assembly, resulting in errors in the fitting of the magnetic tile. The distance between the fitted magnetic tile and the rotor is not equal, the rotor cannot be assembled or the assembly accuracy is poor, and there is too much glue overflow at the end, further increasing the risk of subsequent falling off. Summary of the Invention

[0005] The present invention addresses the disadvantage of the prior art that the structure of the magnetic tile and the casing being fitted together may cause glue scraping. The glue overflow caused by the scraping has a high probability of falling into the rotor operating area during subsequent use, affecting the performance of the motor. The invention provides a magnetic tile and casing glue coating assembly device that can significantly reduce the probability of the scraping glue phenomenon.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A device for gluing and assembling magnetic tiles and a housing includes an expansion and contraction magnetic attraction mechanism and a housing assembly station. The expansion and contraction magnetic attraction mechanism includes a base and a plurality of magnetic attraction positioning blocks distributed in a ring that can reciprocate along the radial direction of the ring and are used to attract the glued magnetic tiles. The bottom of each magnetic attraction positioning block is provided with a slide seat that slides along the guide of the base. Each slide seat is slidably engaged with a mating block. When the mating block rises or falls, the mating block drives the slide seats to move closer to or away from each other. A lifting drive component is provided on the casing assembly station. When the expansion and contraction magnetic mechanism is placed on the casing assembly station and the lifting drive component is lifted, the matching block rises, the magnetic positioning blocks are radially approached, and the adhesive layer with adhesive magnetic tiles on the magnetic positioning block is matched with the inner wall of the assembled casing; when the lifting drive component descends, the matching block descends and resets, the magnetic positioning block is radially away, and the adhesive layer with adhesive magnetic tiles on the magnetic positioning block is in contact with the inner wall of the casing.

[0007] By adopting the above scheme, an expansion and contraction magnetic attraction mechanism is added to the magnetic tile and casing assembly equipment. The expansion and contraction magnetic attraction mechanism is in an expanded state under normal conditions, that is, the magnetic positioning blocks are radially separated; the expansion magnetic attraction mechanism will contract inwardly when subjected to upward top pressure, that is, the magnetic positioning blocks are radially close to each other. Before the casing is assembled, the mechanism first pre-positions and absorbs the magnetic tile, and then contracts under the top pressure of the jacking drive component at the casing assembly position. When the casing is installed, it can ensure that the glue layer of the magnetic tile does not stick to the casing. After the casing is installed, the jacking drive component descends and removes the top pressure. As the magnetic positioning blocks move radially away from each other, the glue layer of the magnetic tile will contact the inner wall of the casing and adhere to it. Before curing, the mechanism can always keep the glue layer of the magnetic tile in contact with the inner wall of the casing, avoid the magnetic tile from offset, and improve the assembly accuracy after subsequent bonding. The device can significantly reduce the probability of glue scraping when the magnetic tile is bonded to the casing, and can also reduce the probability of magnetic tile offset before the glue cures, thereby improving the final assembly accuracy.

[0008] Preferably, an elastic member is provided between the slide seat and the matching block to drive the matching block to move downward.

[0009] With the above solution, the provision of the elastic member enables the matching block to descend quickly, thereby increasing the expansion speed of the magnetic positioning block.

[0010] Preferably, it also includes a heating and curing station and a loading and unloading robot that transfers the expansion and contraction magnetic attraction mechanism from the casing assembly station to the heating and curing station. The heating and curing station includes a heating coil and a lifting component that drives the expansion and contraction magnetic attraction mechanism on the station to rise and fall vertically. The expansion and contraction magnetic attraction mechanism is inserted into or detached from the heating coil as the lifting component rises and falls.

[0011] Preferably, an auxiliary pressing component is provided above the heating coil. When the lifting component drives the expansion and contraction magnetic mechanism to rise until the magnetic positioning block is located inside the heating coil, the auxiliary pressing component is inserted between the magnetic positioning blocks and the force of the rubber magnetic tile pressing against the inner wall of the casing is switched from elastic force to rigid force.

[0012] By adopting the above scheme, the setting of the auxiliary pressing component can further increase the stability of glue curing, and the switching from elastic force to rigid force can further reduce the probability of offset during the curing process of the magnetic tile, thereby improving the final assembly accuracy.

[0013] Preferably, the auxiliary pressing component includes a push rod with its tip pointing downward and a buffer positioning pressure ring that is sleeved on the outside of the push rod and vertically raised and lowered along the push rod. When the lifting component rises, the buffer positioning pressure ring elastically presses against the upper end of the casing and the push rod is inserted from the center of the casing between the magnetic positioning blocks.

[0014] By adopting the above solution, the buffer positioning pressure ring can play a positioning role, and the push rod is inserted between the magnetic positioning blocks to fill the gap between the magnetic positioning blocks due to the radial distance, further reducing the probability of relative displacement between the magnetic tile and the casing during the curing process of the glue layer.

[0015] Preferably, the heating and curing station is provided with an avoidance structure to avoid interference with the loading and unloading robots. The avoidance structure includes a support seat for supporting the expansion and contraction magnetic attraction mechanism and a translation drive member that drives the support seat to move horizontally to approach or move away from the position below the heating coil.

[0016] By adopting the above solution, the translation of the support seat can prevent the loading and unloading robot from touching the heating coil when placing the expansion and contraction magnetic attraction mechanism.

[0017] Preferably, it also includes a CNC dividing plate, which rotates intermittently at a preset angle. The CNC dividing plate has gluing and magnetizing stations, casing assembly stations, curing and transfer stations, and unloading and transfer stations evenly distributed at intervals in the circumferential direction. The expansion and contraction magnetic attraction mechanism circulates on the gluing and magnetizing stations, casing assembly stations, curing and transfer stations, and unloading and transfer stations as the CNC dividing plate rotates.

[0018] By adopting the above scheme, the expansion and contraction magnetic attraction mechanism can be transferred sequentially between multiple workstations through the CNC dividing plate. If multiple expansion and contraction magnetic attraction mechanisms are provided, continuous operation between multiple processes can be achieved, thereby improving work efficiency.

[0019] Preferably, a magnetic attraction mechanism for absorbing and releasing the magnetic tiles is provided directly above the gluing and magnetizing station, and a gluing mechanism is provided near the magnetic attraction mechanism, which can approach or move away from the magnetic tile and apply glue vertically to the outer surface of the magnetic tile when approaching.

[0020] With the above solution, the gluing mechanism is located near the magnetic attraction mechanism. After gluing the magnetic tiles on the magnetic attraction mechanism, the magnetic attraction mechanism can be directly lowered and the magnetic tiles can be assembled on the expansion and contraction magnetic attraction mechanism on the gluing and magnetic sticking station. The space design is reasonable.

[0021] Preferably, the magnetic attraction mechanism includes a magnetic attraction part and a magnetic pushing part which is coaxially lifted and lowered above the magnetic attraction part and adheres to the surface of the magnetic attraction part when descending and pushes the adhesive magnetic tile adsorbed by the magnetic attraction part out of the magnetic attraction part.

[0022] By adopting the above solution, the magnetic attraction part absorbs and positions the magnetic tile so that the gluing mechanism can apply glue to the outer wall of the magnetic tile, and the magnetic pushing part can push the glued magnetic tile vertically downward along the surface of the magnetic attraction part.

[0023] Preferably, the magnetic attraction component has a preset number of magnetic surfaces corresponding to the casing, a magnetic tile loading disk is provided outside the CNC dividing disk, the magnetic attraction mechanism is provided on a rotating frame and switches between the magnetic tile loading disk and the gluing and magnetizing station as the rotating frame rotates, the magnetic attraction component is rotatably provided on the rotating frame, the fixed end of the magnetic pushing component is fixed on the rotating frame, and the discharge port of the magnetic tile loading disk is provided with a pushing component for pushing the magnetic tiles one by one along the magnetic surface of the magnetic attraction mechanism.

[0024] By adopting the above scheme, the magnetic attraction part can simultaneously attract several magnetic tiles corresponding to the casing. After all the magnetic tiles are coated with glue, they can be pushed to the expansion and contraction magnetic attraction mechanism below at the same time. The magnetic attraction part can switch between the magnetic tile loading tray and the glue coating and magnetization station through the rotation of the rotating frame. Under the coordinated action of the magnetic tile loading tray and the pushing component, the automatic adsorption and automatic discharge of the magnetic tiles can be realized, with a high degree of automation.

[0025] Preferably, the gluing mechanism includes a glue gun and a dual-coordinate robot that drives the glue gun to move vertically and horizontally. The gluing port of the glue gun is designed to be a concave arc shape that fits the outer surface of the magnetic tile. There is a gap between the glue layer and the edge of the outer surface of the magnetic tile, and the gap ranges from 0.5 to 2 mm. The height range of the gluing port is 0.2 to 1 mm.

[0026] Using the above solution, the concave arc design of the glue outlet fits the outer surface of the magnetic tile, the height of the glue application port is small, and a small amount of glue can be controlled to be evenly extruded. There is a gap between the glue application port and the two sides of the magnetic tile, and when applying glue, a gap will also be reserved above and below the magnetic tile. These gaps are reserved for glue filling positions. When the glue layer of the magnetic tile contacts the casing, the glue layer will be slightly squeezed, causing a small amount of glue to overflow to the surroundings. The glue filling position is used to fill these overflowing trace glue.

[0027] The present invention has significant technical effects due to the adoption of the above technical solutions: The jacking mechanism is adapted to move the magnetic tile away from the casing and into engagement with the casing, so that the jacking mechanism can be moved away from the casing and into engagement with the casing, thereby preventing the jacking mechanism from moving away from the casing and into engagement with the casing. An auxiliary pressing component is added to cooperate with the curing station to further improve the stability of glue curing. This design switches the contact force between the magnetic tile glue layer and the housing from elastic force to rigid force, which can further reduce the probability of the magnetic tile deflecting relative to the housing during curing. Several expansion and contraction magnetic suction mechanisms automatically rotate in sequence between multiple workstations, realizing automatic loading of magnetic tiles, automatic gluing, automatic assembly with the casing, automatic curing, and automatic unloading after curing. The entire process is automatic with a high degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS

It also includes a number of expansion and contraction magnetic suction mechanisms 30 that reciprocate between the gluing and magnetizing station, the casing assembly station, the curing and transfer station, the curing station, and the unloading and transfer station.

[0032] A numerical control indexing plate 5 is provided on the machine base 1, see Figure 5As shown, the CNC indexing plate 5 rotates intermittently at 90° angles. This CNC indexing plate 5 is conventional technology, and its structure is not described here in detail. Uniformly spaced along its circumference are the gluing and magnetizing stations, the housing assembly station, the curing and transfer station, and the unloading and transfer station. When the expansion and contraction magnetic attraction mechanism 30 is positioned on the CNC indexing plate 5, it sequentially rotates between the four stations as the CNC indexing plate 5 rotates.

[0033] The expansion and contraction magnetic attraction mechanism 30 is the core design point of this device, combined with Figure 6-Figure 7 As shown, the expansion and contraction magnetic attraction mechanism 30 includes a base 3001 and four magnetic attraction positioning blocks 3002 distributed in a ring that can move back and forth along the radial direction of the ring and are used to adsorb the adhesive magnetic tiles. Guide ridges 3003 are convex on both sides of the magnetic attraction positioning blocks 3002. Magnets are embedded and fixed in the middle of the magnetic attraction positioning blocks 3002 at intervals in the longitudinal direction. A slide 3008 that slides with the base 3001 is provided at the bottom of each magnetic attraction positioning block 3002. Each slide 3008 is slidably matched with a matching block 3005. An oblique guide groove is provided on the slide 3008. The outer wall of the matching block 3005 is provided with an oblique guide block that cooperates with the oblique guide groove. One of the slides A positioning protrusion 3004 is provided on the upper end of the seat 3008, which is inserted into the notch at the bottom of the casing when the casing is inserted. When the mating block 3005 rises or falls, the mating block 3005 drives the slides 3008 to move closer to or away from each other. A limit block 3006 is provided horizontally on the bottom of the mating block 3005. An elastic member 3007 is provided on the outer sleeve of the mating block 3005, which is in contact with the bottom of the slide 3008 and the limit block 3006 respectively and is used to drive the mating block 3005 to move downward. The elastic member 3007 is a spring. Therefore, in normal state, the mating block 3005 is in a relatively distant state, and the expansion and contraction magnetic attraction mechanism 30 is in an expanded state.

[0034] A magnetic tile loading tray 2 is provided on the magnetic tile feeding station, and a magnetic tile transfer assembly is provided between the magnetic tile loading tray 2 and the gluing and magnetizing station. The magnetic tile transfer assembly includes a rotating frame 19 and two groups of magnetic attraction mechanisms respectively assembled at both ends of the rotating frame 19. The middle column 20 of the rotating frame 19 is rotatably set on the machine base 1 and is driven by a motor to rotate. The two groups of magnetic attraction mechanisms are switched between the magnetic tile loading tray 2 and the gluing and magnetizing station in turn as the rotating frame 19 rotates.

[0035] Specific structure reference Figure 3-Figure 4As shown, a plurality of placement slots 201 are arranged in parallel and at intervals on the magnetic tile loading tray 2. The magnetic tile loading tray 2 slides on the machine base 1 through the guide of the screw slide assembly. A pushing assembly 29 is arranged above the magnetic tile loading tray 2. The pushing assembly 29 moves back and forth along the length direction of the placement slot 201 through the screw slide assembly and can completely escape from the placement slot 201. The pushing block 291 of the pushing assembly 29 advances the distance of one magnetic tile in a single time along the pushing direction until it advances into the placement slot 201. After all the magnetic tiles are emptied, they quickly retreat to be out of the placement slot 201, and then the magnetic tile loading plate 2 advances the distance of a placement slot 201, and the pushing assembly 29 advances again to carry out a new round of pushing. A pushing component is provided on the machine base 1 to vertically guide the magnetic tiles pushed out by the pushing assembly 29 upward to the magnetic attraction mechanism. The pushing component includes a positioning seat 27 for preventing the magnetic tiles from tipping over, a lifting block 28 that is lifted and lowered in the positioning seat 27, and a lifting cylinder that drives the lifting block 28 to rise and fall.

The upper end of the magnetic attraction part 25 is vertically guided for lifting and lowering. There is a pushing magnetic part 26 that adheres to the surface of the magnetic attraction part 25 when descending and pushes the rubber magnetic tile adsorbed by the magnetic attraction part 25 out of the magnetic attraction part. The upper end of the pushing magnetic part 26 is rotatably arranged on the end of the piston rod of a pushing magnetic cylinder 24. The pushing magnetic cylinder 24 is fixed to the upper end of the lifting plate 21 with the piston rod vertically facing downward.

[0037] Gluing mechanism 3 is symmetrically arranged on both sides above the gluing and magnetizing station. Figure 8-Figure 9 As shown, when the magnetic attraction mechanism moves to above the glue coating and magnet sticking station, the glue coating mechanism 3 approaches the magnetic attraction mechanism and vertically coats glue on the outer surface of the magnetic tile thereon.

[0038] The gluing mechanism 3 includes a glue gun 301 and a dual-coordinate robot 302 that drives the glue gun 301 to move vertically and horizontally. The dual-coordinate robot 302 is a prior art and the specific structure is not described in detail. The gluing port 3011 of the glue gun 301 is designed to be a concave arc shape that fits the outer surface of the magnetic tile. The height of the gluing port 3011 is 0.5 mm. As the magnetic attraction part 25 rotates, the gluing mechanism 3 can complete the gluing of the four magnetic tiles. A hopper 3012 for gluing is provided on the glue gun 301 below the gluing port 3011.

[0039] A visual camera 4 is provided on the machine base 1 near each set of gluing mechanisms 3. Figure 1-Figure 2As shown, the visual camera 4 is a prior art and its structure is not described in detail. After each magnetic tile is coated with glue, the visual camera 4 takes a photo. The controller compares the glue coating area, glue coating shape and reflection degree reflected in the photo with the qualified group photo. If it is within the allowable preset error range, the glue coating is determined to be qualified; otherwise, the glue coating is determined to be unqualified. At this time, the controller sends a signal to the alarm, and the alarm sounds an alarm.

[0040] The casing dust removal station is located between the casing feeding station and the casing assembly station. A six-axis robot is arranged between the casing dust removal station and the casing feeding station. A casing assembly robot is arranged between the casing dust removal station and the casing assembly station.

[0041] The casing on the casing feeding station is manually placed on the material tray, and is grabbed by the six-axis robot assembled on the machine base 1 and placed on the casing blowing and cleaning station. The casing feeding station and the six-axis robot are not shown in the figure, both of which are prior art. A casing grabbing robot 7 is set between the casing dust removal station and the casing assembly station, see Figure 5 As shown, the robot is also an existing technology. It is driven by a motor to achieve 180° reciprocating rotation, a cylinder or a screw slide assembly to achieve vertical lifting, and a pneumatic gripper to achieve grasping or releasing the casing.

The negative pressure tube is connected to a vacuum cleaner, which is not shown. A detector for detecting the placement angle of the casing is provided on the placement table 6. After the six-axis robot grasps the casing, the casing is inserted into the casing positioning sleeve 601. According to the detection of the detector, the controller controls the casing positioning sleeve 601 to rotate to the angle required for the casing grasping robot 7 to grasp.

[0043] A lifting drive member 18 is provided on the housing assembly station and below the numerical control indexing plate 5, see Figure 5 As shown, the lifting drive component 18 is a lifting cylinder. When the expansion and contraction magnetic mechanism 30 is placed on the casing assembly station and the lifting drive component 18 is lifted, the matching block 3005 rises, the magnetic positioning blocks 3002 are radially approached, and the adhesive layer with adhesive magnetic tiles on the magnetic positioning block 3002 is matched with the inner wall of the assembled casing; when the lifting drive component 18 descends, the matching block 3005 descends and resets, the magnetic positioning block 3002 is radially away, and the adhesive layer with adhesive magnetic tiles on the magnetic positioning block 3002 is in contact with the inner wall of the casing.

[0044] A loading and unloading robot 8 is arranged between the curing station and the curing transfer station. The robot is an existing three-coordinate robot. A transfer robot 9 is arranged outside the unloading transfer station to remove the cured product on the expansion and contraction magnetic suction mechanism 30 at the station to the cooling station. The transfer robot 9 is an existing robot and its structure is not described in detail. Its clamping claws can be raised and lowered and rotated, and the robot can move back and forth along a predetermined path.

[0045] There are six groups of parallel heating and curing stations, see Figure 10-12 As shown, the heating and curing station includes a heating coil 12 and a lifting component 16 that drives the expansion and contraction magnetic attraction mechanism 30 on the station to rise and fall vertically. The lifting component 16 is a lifting cylinder. The expansion and contraction magnetic attraction mechanism 30 is inserted into or detached from the heating coil 12 as the lifting component 16 rises and falls. An auxiliary pressing component is provided above the heating coil 12. When the lifting component 16 drives the expansion and contraction magnetic attraction mechanism 30 to rise until the magnetic positioning block 3002 is located in the heating coil 12, the auxiliary pressing component is inserted between the magnetic positioning blocks 3002 and the force of the adhesive magnetic tile pressing against the inner wall of the casing is switched from elastic force to rigid force. The auxiliary pressing component includes a push rod 14 with a downward tip and a buffer positioning pressure ring 13 that is sleeved on the outside of the push rod 14 and rises and falls vertically along the push rod 14. When the lifting component 16 rises, the buffer positioning pressure ring 13 elastically presses against the upper end of the casing and the push rod 14 is inserted from the center of the casing between the magnetic positioning blocks 3002.

[0046] The auxiliary pressing component is fixed to the lower end of the Y-axis beam of the loading and unloading robot 8, see Figure 11 As shown, the heating and curing station is equipped with an avoidance structure to prevent interference with the loading and unloading robot 8. The avoidance structure includes a support base 10 for supporting the expansion and contraction magnetic attraction mechanism 30 and a translation drive 17 that drives the support base 10 horizontally toward or away from the position below the heating coil 12. The support base 10 slides on the machine base 1 through the cooperation and guidance of the guide rail and slider assembly 11. The translation drive 17 is a horizontal drive cylinder. A temperature control sensor 15 is located near each heating coil 12.

[0047] The logic of assembly using this equipment is as follows: 1. Magnetic tile adsorption flow: including three steps: feeding at the magnetic tile feeding station, material absorption and transportation by the magnetic absorption mechanism, and material pushing by the magnetic absorption mechanism; First, the pushing block 291 of the pushing assembly 29 advances the distance of a magnetic tile, so that a magnetic tile is pushed into the positioning seat 27; then, it moves to the magnetic attraction mechanism at the magnetic tile feeding station, and its magnetic attraction part 25 descends to the top of the positioning seat 27 and one of the magnetic attraction surfaces is rotated to the angle required for assembly; then, the ejecting cylinder lifts the magnetic tile in the positioning seat 27, and the magnetic tile passes through the positioning seat 27 and rises along the current corresponding magnetic attraction surface until it is completely adsorbed on the magnetic attraction surface; further, the magnetic attraction part 25 rotates 90°, and the pushing assembly 29 advances the distance of a magnetic tile again, and the ejecting cylinder continues to eject, completing the adsorption of the next magnetic tile on the magnetic attraction part 25, and repeating the above steps until all 4 magnetic tiles are adsorbed. Finally, the rotating frame 19 rotates, and the group of magnetic attraction mechanisms carries the 4 magnetic tiles to rotate between the two groups of glue coating mechanisms 3. At the same time, the other group of magnetic attraction mechanisms completes the pushing operation and rotates to the magnetic tile feeding station to wait for the adsorption of new magnetic tiles; 2. Apply glue and position the magnetic tiles: The magnetic part 25 rotates until there are two magnetic surfaces facing the two groups of gluing mechanisms 3 respectively, and the two groups of glue guns 301 synchronously approach the gluing port 3011 to fit the outer wall of the magnetic tile, and the glue gun 301 discharges glue and moves slowly from top to bottom, evenly coating the outer wall of the magnetic tile with glue, and there is a 0.8mm gap between the glue layer and the upper and lower ends and the left and right ends of the magnetic tile; then, the visual camera 4 takes pictures, and after the inspection is qualified, the glue gun 301 retreats and rises to reset; further, the magnetic part 25 rotates 90°, and the glue gun 301 moves forward again and applies glue to the other two magnetic tiles from top to bottom, takes pictures after gluing, and resets after passing the inspection; finally, the magnetic attraction mechanism as a whole descends to the upper end of the expansion and contraction magnetic attraction mechanism 30 on the gluing and magnetizing station, and as the magnetic pushing part 26 descends, the glued magnetic tiles adsorbed on the surface of the magnetic part 25 are evenly introduced into the magnetic positioning block 3002 of the expansion and contraction magnetic attraction mechanism 30; 3. Casing dust removal and positioning assembly The six-axis robot grabs the casing on the casing feeding station and moves it to the placement table 6 of the casing dust removal station, and is placed on the casing positioning sleeve 601 at a preset angle. The vacuum cleaner is started to perform negative pressure dust collection. At the same time, the expansion and contraction magnetic attraction mechanism 30 with the rubber magnetic tile rotates with the rotation of the CNC indexing plate 5 to the casing assembly station, the jacking drive part 18 is lifted, the magnetic positioning block 3002 is relatively close, and the expansion and contraction magnetic attraction mechanism 30 is in a contracted state. After the casing dust collection is completed, the casing grabber is The robot 7 first descends to grip the casing, then ascends and rotates 180°, then descends again to concentrically sleeve the magnetic positioning block 3002 of the expansion and contraction magnetic mechanism 30 in the contracted state. At this time, the adhesive layer of the adhesive-coated magnetic tile matches the inner wall of the casing; finally, the lifting drive member 18 descends and resets, and the magnetic positioning block 3002 elastically resets and moves away from each other, so that the adhesive layer of the adhesive-coated magnetic tile fits the inner wall of the casing. The glue generated by the fitting will fill the uncoated area of ​​the magnetic tile to avoid glue overflow. 4. Glue curing The CNC indexing plate 5 rotates 90 degrees, and the expansion and contraction magnetic attraction mechanism 30 after the casing is assembled is transferred to the curing transfer station, and the loading and unloading robot 8 grabs the expansion and contraction magnetic attraction mechanism 30 and places it on the supporting seat 10; then, the translation drive member 17 retracts to drive the supporting seat 10 to move to just below the heating coil 12; then, the lifting component 16 rises, and the expansion and contraction magnetic attraction mechanism 30 rises with the supporting seat 10, and the casing on it is inserted into the heating coil 12. At the same time, the upper end of the casing is elastically pressed against the buffer positioning pressure ring 13, and is located at the buffer positioning The ejector rod 14 at the center of the pressure ring 13 is inserted between the magnetic positioning blocks 3002 of the expansion and contraction magnetic attraction mechanism 30 to prevent the magnetic positioning blocks 3002 from retreating or deflecting, thereby ensuring a stable curing process. After the preset curing time, the lifting component 16 first descends to drive the support seat 10 to descend and reset, and the translation drive member 17 extends to drive the support seat 10 to move outward to within the travel range of the loading and unloading robot 8. Finally, the loading and unloading robot 8 grabs the expansion and contraction magnetic attraction mechanism 30 with the cured workpiece and moves it to the curing transfer station. 5. Transfer cooling The CNC dividing plate 5 continues to rotate 90°, and the expansion and contraction magnetic attraction mechanism 30 carrying the solidified workpiece flows to the unloading transfer station. The transfer robot 9 moves back and forth in a straight line between this station and the cooling station. The transfer robot 9 first clamps the solidified workpiece, carries the workpiece up to separate from the expansion and contraction magnetic attraction mechanism 30, then rotates 180° and carries the workpiece to the cooling station to release the workpiece. The expansion and contraction magnetic attraction mechanism 30 above the station flows to the gluing and magnetizing station with the next 90° rotation of the CNC dividing plate 5, waiting for the start of the next cycle.
