Detailed Implementation

[0014] The present invention will be specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] like Figure 1 — Figure 10As shown, this embodiment discloses a housing mounting magnetic tile device, including a frame 1, on which a mounting platform 2 is provided. The positioning mold 3 is the core positioning component, which is circular in shape, with four magnetic tile positioning and fitting positions 31 evenly opened on its peripheral wall. Each fitting position is an arc-shaped groove, and a positioning clamping groove 32 is formed between adjacent fitting positions for accommodating the positioning clamp.

[0016] The positioning mold 3 is mounted on the mounting platform 2 via the third bracket 8. The lifting plate 81 moves up and down within the third bracket 8 via a guide sleeve and guide rod structure. A tube seat 82, a cylindrical metal part with a hollow interior, is fixedly mounted at the center of the upper surface of the lifting plate 81. The positioning mold 3 is fixed to the upper end face of the tube seat 82 by bolts. The piston rod of the fifth cylinder 87 is connected to the center of the lower surface of the lifting plate 81. The cylinder body of the fifth cylinder 87 is fixed to the bottom of the third bracket 8 and is used to drive the lifting plate 81 and the positioning mold 3 to move up and down.

[0017] The outer wall of the tube seat 82 is tightly fitted with a second pulley 85. A servo motor 83 is also fixedly installed on the lower surface of the lifting plate 81. The output axis of the servo motor 83 passes through the lifting plate 81 and is connected to the first pulley 84. The first pulley 84 and the second pulley 85 are connected by a synchronous belt 86 with a transmission ratio of 1:1. This is used to drive the tube seat 82 and the positioning mold 3 to rotate, with a positioning accuracy of ±0.1 degrees.

[0018] The upper sidewall of the tube seat 82 has vertical holes 812 along the axial direction, each vertical hole 812 corresponding to and communicating with a positioning clamp positioning groove 32. The unloading plate 89 is disc-shaped, with a diameter smaller than the inner diameter of the tube seat 82, and is coaxially arranged in the inner hole of the tube seat 82, and can move up and down along the inner hole of the tube seat 82. The side of the unloading plate 89 is integrally formed with symmetrical L-shaped unloading push rods 811, the vertical section of which passes through the vertical hole 812 of the tube seat 82 and extends into the positioning clamp positioning groove 32. The end of the unloading push rod 811 is rounded to avoid scratching the positioning clamp.

[0019] The center of the lower surface of the unloading plate 89 is connected to the piston rod of the unloading cylinder 88 via the connecting rod 810. The cylinder body of the unloading cylinder 88 is fixed to the bottom of the third bracket 8 and located next to the fifth cylinder 87. It is used to drive the unloading plate 89 to rise and fall, thereby driving the unloading push rod 811 to extend and retract, so as to push out the finished product casing.

[0020] II. Specific Structure and Operation of the Magnetic Tile Pushing Station In this embodiment, three magnetic tile pushing stations 4 are set up, namely the first magnetic tile pushing station, the second magnetic tile pushing station and the third magnetic tile pushing station. The first and second magnetic tile pushing stations are symmetrically distributed on both sides of the positioning mold 3, and the third magnetic tile pushing station is opposite to the housing pushing station 6 and is set on the other two sides of the positioning mold 3, forming a four-equal distribution structure in a circle.

[0021] Taking the first magnetic tile pushing station as an example, its structure is as follows: The first support 41 of the first magnetic tile pushing station is vertically fixed to the left side of the mounting platform 2. The first support 41 is equipped with a magnetic tile conveyor 42, a material transfer robot 43, and a pushing robot 44.

[0022] The side plates 421 of the magnetic tile conveyor table 42 are two parallel steel plates. The front ends of the two side plates 421 are connected to the drive roller via a rotating shaft, and the rear ends are connected to the driven roller via a rotating shaft. The drive roller is driven by a stepper motor. A conveyor belt 422 is tensioned and wrapped around the drive roller and the driven roller. The surface of the conveyor belt 422 is covered with a rubber anti-slip layer for smooth conveying of the magnetic tiles. The magnetic tiles are arc-shaped tiles made of neodymium iron boron permanent magnets.

[0023] The material transfer robot 43 is located directly above the output end of the magnetic tile conveyor 42, and includes a first cylinder 431 and a transfer plate 432. The cylinder body of the first cylinder 431 is fixed to the bottom surface of the horizontal section of the first support 41, with the piston rod facing upwards. The transfer plate 432 is a rectangular steel plate, the center of which is threaded to the top of the piston rod of the first cylinder 431, and can move up and down with the piston rod. A material trough 433 is provided in the middle of the side wall of the transfer plate 432 facing the conveyor belt 422. The material trough 433 is an arc-shaped groove, the curvature of which matches the inner arc of the magnetic tile. Magnetic rubber sheets are attached to the bottom of the groove to enhance the adsorption force.

[0024] The pushing robot 44 is located below the transfer plate 432 and includes a second cylinder 441 and a pushing plate 442. The cylinder body of the second cylinder 441 is fixed to the bottom surface of the horizontal section of the first support 41, located to the right of the first cylinder 431, with the piston rod horizontally facing right. The pushing plate 442 is a rectangular steel plate, the center of which is threaded to the front end of the piston rod of the second cylinder 441, and can move left and right with the piston rod. A finger cylinder is installed at the pushing end of the pushing plate 442, and the two clamping ends of the finger cylinder are respectively connected to the clamping plates 444. Each of the two clamping plates 444 has a slot 443 on its facing sidewall. The slot 443 is a rectangular groove, and the center line of the slot 443 is perpendicular to the moving direction of the pushing plate 442, for tightly inserting the magnetic tile.

[0025] The operation flow of the magnetic tile pushing station: When the stepper motor starts, the conveyor belt 422 rotates clockwise, transporting the magnetic tile to be installed from the left end of the conveyor platform to the right. When the magnetic tile reaches the right end (output end) of the conveyor platform, the outer arc surface of the magnetic tile faces the output end of the conveyor platform. The material trough 433 is blocked at the outlet of the conveyor belt 422. The piston rod of the first cylinder 431 extends and drives the material transfer plate 432 to move downward. At this time, the rightmost magnetic tile of the output end of the quasi-conveyor table is attached to the material trough 433 and is transferred to the pushing robot 44 below. The piston rod of the first cylinder 431 continues to extend until the lower part of the magnetic tile is inserted into the slot 443 of the push plate 442. At this time, the magnetic tile is tightly inserted into the slot 443 of the card plate 444, with the inner arc surface facing outward. The piston rod of the second cylinder 441 extends, pushing the pusher plate 442 forward and pushing the magnetic tile out of the slot 443. The outer arc surface of the magnetic tile fits into the magnetic tile positioning and fitting position 31 of the positioning mold 3. The magnetic tile positioning and fitting position 31 is provided with an arc-shaped bottom surface. The finger cylinder is released and returns to its original position, completing the pushing of a single magnetic tile.

[0026] III. Specific Structure and Actions of the Positioning Clamp Pushing Station This embodiment sets up two positioning clamp pushing stations 5, namely the upper positioning clamp pushing station and the lower positioning clamp pushing station, symmetrically distributed above and below the positioning mold 3. Taking the upper positioning clamp pushing station as an example, its structure is as follows: The positioning clamp vibratory feeder 51 at the positioning clamp pushing station 5 is a circular stainless steel disc with a built-in spiral track. A photoelectric sensor is installed at the track outlet to detect whether the positioning clamp is in position. The base of the positioning clamp vibratory feeder 51 is fixed to the bracket on the rear side of the mounting platform 2, and its output end is connected to a guide plate 52 via a flexible hose. The guide plate 52 is a long strip of steel plate, and a guide groove 521 is opened on the upper surface of the guide plate 52 to guide the positioning clamps in a single-row conveying.

[0027] The output end of the guide trough 521 (the end closest to the positioning mold 3) is provided with a limiting block. The limiting block has an upper-opening limiting groove, which is a rectangular groove and communicates with the end of the guide trough 521. A scraper plate 54 is provided directly above the limiting groove. The scraper plate 54 is driven to move up and down by a third cylinder 53. The cylinder body of the third cylinder 53 is fixed to the upper surface of the guide plate 52, and the piston rod faces downward. It is used to push the positioning clamp output from the guide trough 521 into the limiting groove.

[0028] An XZ motion module 55 is mounted above the scraper plate 54. The XZ motion module 55 consists of an X-axis linear module (cylinder-driven structure), a Z-axis linear module (cylinder-driven structure), and a connecting plate. The X-axis linear module is positioned along the left-right direction of the mounting platform 2 and fixed to a column on the rear side of the mounting platform 2. The Z-axis linear module is vertically fixed to the slider of the X-axis linear module, and the connecting plate is fixed to the slider of the Z-axis linear module. A swing arm 56 is hinged to the lower end of the connecting plate. The swing arm 56 is a rectangular steel plate, with one end hinged to the connecting plate via a pin. A servo motor is mounted on the pin and fixed to the connecting plate, driving the swing arm 56 to rotate around the pin. The rotation angle range is 0-90 degrees (0 degrees horizontally and 90 degrees vertically). A positioning clamp slot 561 is formed at the other end (free end) of the swing arm 56, with the opening facing the free end of the swing arm 56 and matching the shape of the positioning clamp.

[0029] The motion flow of the upper positioning clamp pushing station: When the positioning clamp vibratory feeder 51 is started, the internal electromagnet generates an alternating magnetic field, which drives the positioning clamp to move upward along the spiral track and enter the guide groove 521 of the guide plate 52 from the output end. The positioning clamp is conveyed forward in a single row in the guide groove 521. When the first positioning clamp reaches the output end of the guide groove 521, the photoelectric sensor detects the signal and the vibratory feeder stops. The piston rod of the third cylinder 53 extends and pushes the scraper plate 54 downward. The bottom surface of the scraper plate 54 contacts the positioning clamp in the guide groove 521 and pushes it into the limiting groove. The scraper plate 54 moves down to ensure that the positioning clamp is fully inserted into the limiting groove. The X-axis slider of the XZ motion module 55 drives the Z-axis module and the swing arm 56 to move to the left until the free end of the swing arm 56 is directly above the limiting groove. The Z-axis slider then drives the swing arm 56 to move downward until the height of the swing arm 56 is the same as the height of the limiting groove. When the servo motor starts, it drives the swing arm 56 to rotate 90 degrees around the pin shaft, changing from the horizontal direction to the vertical direction. At this time, the opening of the positioning clamp in the slot 561 faces downward and is aligned with the positioning clamp in the limit slot. The Z-axis slider continues to drive the swing arm 56 to move downwards. The upper part of the positioning clamp is guided into the positioning clamp slot 561 by gravity and the inclined surface of the slot 561. The two side walls of the slot 561 clamp the positioning clamp. The servo motor rotates 90 degrees in the opposite direction, and the swing arm 56 returns to the horizontal direction. The X-axis slider drives the swing arm 56 to move to the right until the free end of the swing arm 56 is aligned with the corresponding positioning clamp positioning groove 32 on the positioning mold 3. The Z-axis slider drives the swing arm 56 to move downward, pushing the positioning clamp out of the slot 561. The opening of the positioning clamp engages with the two side walls of the positioning clamp positioning groove 32, completing the pushing of a single positioning clamp.

[0030] IV. Specific Structure and Operation of the Housing Pushing Station The housing pushing station 6 is located to the right of the positioning mold 3, opposite to the third magnetic tile pushing station. Its base 61 is fixed to the edge of the mounting platform 2. Two parallel guide rails 62 are fixed on the upper surface of the base 61, and a slider that mates with the guide rails 62 is fixed on the slide plate 64, which can slide left and right along the guide rails 62. The slide plate 64 is a rectangular steel plate with an insertion hole 641 in its center. The insertion hole 641 is a circular through hole for inserting the housing.

[0031] A fourth cylinder 63 is fixed to the left side of the base 61. The piston rod of the fourth cylinder 63 faces right and its end is connected to the center of the side of the slide plate 64 through a floating joint. It is used to drive the slide plate 64 to move left and right along the guide rail 62. A backing plate 65 is fixed to the right side of the base 61. The backing plate 65 is a rectangular steel plate with an arc-shaped groove 651 machined on its right end face. The radius of the arc-shaped groove 651 is the same as the outer radius of the positioning mold 3. The arc length covers half of the circumference of the positioning mold 3. The groove depth is 5 mm. It is used to contact the outer arc surface of the magnetic tile on the positioning mold 3 when the machine housing is pushed into place, so as to correct the coaxiality of the machine housing.

[0032] The operation flow of the casing pushing station: The worker manually aligns the lower end of the housing to be assembled with the insertion hole 641 of the slide plate 64, and forcefully inserts the small end of the housing into the insertion hole 641 until the large end of the housing is in contact with the right side of the slide plate 64. At this time, the central axis of the housing coincides with the central axis of the insertion hole 641. The piston rod of the fourth cylinder 63 extends, pushing the slide plate 64 to move to the right along the guide rail 62 until the housing is close to the top of the positioning mold 3, and the housing and the positioning mold 3 are completely coaxial. The slide plate 64 stops moving and waits for the clamping station 7 to start moving.

[0033] V. Specific Structure and Operation of the Clamping Station The clamping station 7 is located directly above the positioning mold 3 and includes a second bracket 71, a clamping cylinder 72, a horizontal plate 73, a guide rod 74, a guide sleeve 75, and a clamping plate 76. The second bracket 71 spans across the positioning mold 3 and is fixed to the front and rear edges of the mounting platform 2. The clamping cylinder 72 is fixed at the center of the second bracket 71.

[0034] The horizontal plate 73 is a rectangular steel plate, and its center is threaded to the bottom end of the piston rod of the clamping cylinder 72, allowing it to move up and down with the piston rod. A guide rod 74 is fixed to each end of the horizontal plate 73; the guide rod 74 is a light axis extending downwards perpendicular to the plane of the horizontal plate 73. A guide sleeve 75 is fixed to each of the two side columns of the second support 71 to guide the horizontal plate 73 to move up and down smoothly.

[0035] A pressing plate 76 is fixed at the center of the lower surface of the horizontal plate 73. The pressing plate 76 is disc-shaped, made of polyurethane, and has a smooth surface. Its outer diameter is smaller than the outer diameter of the housing and larger than the inner diameter of the housing. This ensures that the pressing plate 76 can pass through the inner hole of the housing and fit against the end face of the positioning mold 3 when pressing, while pressing the housing evenly onto the positioning mold 3.

[0036] The operation flow of the clamping station: The piston rod of the fifth cylinder 87 extends, pushing the lifting plate 81 and the positioning mold 3 to move upward until the top surface of the magnetic tile positioning and fitting position 31 of the positioning mold 3 contacts the inner hole end face of the machine housing. At this time, the top surface of the positioning mold 3 is 60 mm higher than the surface of the mounting platform 2. The piston rod of the pressing cylinder 72 extends, pushing the horizontal plate 73 and the guide rod 74 to move downward. The guide rod 74 slides along the guide sleeve 75 to ensure that the horizontal plate 73 descends vertically and avoids tilting. When the lower surface of the clamping plate 76 approaches the end face of the inner hole of the housing, the clamping plate 76 begins to contact the edge of the inner hole of the housing. As the piston rod continues to extend, the clamping plate 76 presses the housing evenly onto the magnetic tile positioning and contact position 31 of the positioning mold 3 until the horizontal plate 73 moves down to the lowest position (end of stroke). At this time, the housing and the positioning mold 3 are tightly fitted, and the magnetic tile is clamped between the inner wall of the housing and the outer wall of the positioning mold 3. The piston rod of the clamping cylinder 72 retracts, causing the horizontal plate 73 and the clamping plate 76 to return to their original position, ready for the next clamping operation.

[0037] VI. Complete Assembly Process The complete assembly process in this embodiment is as follows: 1. The magnetic tile pushing station 4 on the right and the two symmetrical magnetic tile pushing stations first push the magnetic tile to the magnetic tile positioning and bonding position 31 of the positioning mold 3; 2. Subsequently, the positioning clamp push station (5) synchronously pushes the positioning clamp to the positioning clamp positioning slot (32); 3. Servo motor 83 drives the positioning mold 3 to rotate 180°; 4. The magnetic tile pushing station 4 on the right pushes the magnetic tile again, and at the same time, the positioning clamp pushing station (5) on both sides pushes the positioning clamp to complete the uniform distribution of magnetic tiles and positioning clamps around the circle. 5. The worker at the housing pushing station 6 inserts the housing into the insertion hole 641 of the slide plate 64. The fourth cylinder 63 pushes the slide plate 64 to make the housing coaxial with the positioning mold 3. The arc groove 651 of the backing plate 65 contacts the magnetic tile to correct the position. 6. The fifth cylinder 87 drives the lifting plate 81 to rise, so that the positioning mold 3 fits against the inner wall of the machine housing. The pressing cylinder 72 presses down the horizontal plate 73, and the pressing plate 76 passes through the insertion hole 641 to press the machine housing onto the positioning mold 3. 7. The unloading cylinder (88) extends and drives the unloading plate 89 and the L-shaped unloading push rod 811 to push out of the machine housing along the positioning groove 32 of the positioning clamp to complete the unloading.

[0038] This invention achieves fully automated assembly of magnetic tiles, positioning clamps, and housing through collaborative operation of various workstations, solving the problems of low efficiency and poor precision in manual assembly, and is suitable for large-scale production of automotive air conditioning fan motors.
