Description

Technical Field

[0001] This invention relates to the field of magnet assembly technology, and in particular to an iron feeding assembly and its application in the assembly of Heilbeck magnetic components. Background Technology

[0002] For the assembly of a Heilbeck magnetic component, such as Figure 2 As shown, the magnetic assembly is formed by bonding a magnet group and an L-shaped iron piece together. The magnet group is formed by arranging multiple magnets together, and the L-shaped iron piece consists of a top plate and side plates that are perpendicular to each other. The assembly process first involves applying glue to the magnet group, and then placing the L-shaped iron piece on top of the magnet group, so that the top plate of the iron piece is bonded to the top surface of the magnet group, and the side plate of the iron piece is bonded to the side surface of the magnet group. Due to the structure of the L-shaped iron piece, it cannot be placed directly with the top plate on top and the side plate facing down, but rather in various postures. When the robotic arm picks up the iron piece, it cannot directly pick up the iron piece with the top plate on top and the side plate facing down and place it on the magnet group. Therefore, this iron piece placement process is generally done manually, by manually flipping the iron piece over and placing it on the magnet group. This results in low production efficiency, high labor costs, and prevents the entire Heilbeck magnetic assembly process from being fully automated, thus affecting the production efficiency of the entire assembly line. Summary of the Invention

After the taking plate is slid to the magnet assembling channel, the magnet inlet is connected to the magnet outlet, so that the magnet group can be arranged in the magnet groove.

[0020] Further, the application further comprises a straightening station which is arranged between the taking station and the glue dispensing station. The straightening station is provided with an alignment plate, a pushing assembly and a second straightening assembly.

[0051] As Figures 1-16As shown, the present application provides an iron piece feeding assembly 400 for placing an iron piece 100 onto a magnet group 200, the iron piece 100 being L-shaped and composed of a top plate 110 and a side plate 120 perpendicular to each other (as shown in Figure 2 The iron piece 100 is made of ferromagnetic material.

[0052] The present application focuses on Figures 3-4As shown, the iron piece feeding assembly 400 includes a feeding table 401, a transfer table 402, a mechanical hand 403, a turning plate 404, and a first grabbing assembly 405. The feeding table 401 contains the iron pieces 100 that fall on the top surface of the feeding table 401 with the top plate 110 extending upward and the side plate 120 upward. Specifically, the feeding table 401 further includes a hopper 414 and a material plate. The hopper 414 is used to stack the iron pieces 100 and provide the iron pieces 100 to the feeding table 401. The hopper 414 is provided with a gate 415 on the side facing the feeding table 401. The gate 415 can be opened or closed. The height of the gate 415 is higher than the top surface of the feeding table 401. The hopper 414 is connected to the feeding table 401 through the material plate. The material plate is inclined downward toward the feeding table 401. The feeding table 401 is connected with a vibrator. In use, the gate 415 is first opened, and the iron pieces 100 slide into the top surface of the feeding table 401 through the material plate. At the same time, the vibrator is turned on, so that the feeding table 401 vibrates, and the iron pieces 100 are dispersed to different positions. Part of the iron pieces 100 are placed in the posture that the top plate 110 falls on the top surface of the feeding table 401 and the side plate 120 extends upward. The transfer table 402 extends horizontally. The top surface of the transfer table 402 is provided with an iron piece groove 406. The iron piece groove 406 is used for the iron pieces 100 to be embedded in the posture that the top plate 110 is downward and the side plate 120 is upward. The mechanical hand 403 is used to suck and place the iron pieces 100 from the feeding table 401 to the iron piece groove 406 of the transfer table 402. The mechanical hand 403 is any existing automatic device that can visually recognize and complete grabbing along a predetermined path. The mechanical hand 403 can recognize the iron pieces 100 in the posture that the top plate 110 is downward and the side plate 120 is upward, so that after recognizing the iron pieces 100 in this posture, the mechanical hand 403 adsorbs the side plate 120 of the iron piece 100, and the iron piece 100 can be embedded in the iron piece groove 406 in the posture that the top plate 110 is downward and the side plate 120 is upward. The turning plate 404 extends horizontally and can turn around a rotating shaft. The rotating shaft extends horizontally and is located on one side of the transfer table 402. The rotating shaft is connected with a rotating drive motor (not shown in the figure) to drive the turning plate 404 to turn around the shaft, so that the bottom surface of the turning plate 404 is upward and the top surface is downward, or to drive the turning plate 404 to turn around the shaft in the reverse direction to reset, so that the top surface of the turning plate 404 is upward and the bottom surface is downward. The top surface of the turning plate 404 protrudes with a magnetic attraction part 407. After the turning plate 404 turns around the shaft toward the transfer table 402, the top surface of the turning plate 404 covers the top surface of the transfer table 402 downward, so that the magnetic attraction part 407 can be inserted into the iron piece groove 406 downward to adsorb the iron piece 100. The magnetic attraction part 407 is specifically a copper block, and can also be made of other non-ferromagnetic materials. A magnet is embedded in the magnetic attraction part 407 to adsorb the iron piece 100. After the turning plate 404 turns around the shaft in the reverse direction to reset, the iron piece 100 is adsorbed on the top surface of the magnetic attraction part 407 in the posture that the top plate 110 is upward and the side plate 120 is downward. The first grabbing assembly 405 is used to suck and place the iron piece 100 from the turning plate 404 to the top surface of the magnet group 200.

[0053] Preferably, the transfer station 402 can rotate horizontally, in particular, the bottom side of the transfer station 402 is connected with a horizontally rotating rotation driving motor, the rotation driving motor is used for driving the transfer station 402 to rotate horizontally, the top surface of the transfer station 402 is formed with the iron piece grooves 406 at the opposite ends respectively, which are the first iron piece groove 408 and the second iron piece groove 409, so that after the transfer station 402 rotates horizontally by 180 degrees, the magnetic attraction part 407 of the flap 404 can be inserted into one of the first iron piece groove 408 and the second iron piece groove 409 downward, and in the working process, when the flap 404 is attracted to the iron piece 100 in the first iron piece groove 408, the manipulator 403 simultaneously embeds the iron piece 100 in the second iron piece groove 409, the working process is compact, and the working efficiency is high.

[0054] The first gripping assembly 405 is shown in detail Figure 9 As shown, the first gripping assembly 405 includes a first linear module 410, a lifting head 411, a magnetic attraction head 412 and a top rod 413, the lifting head 411 is slidingly arranged on the first linear module 410, the first linear module 410 is any linear module capable of realizing linear motion, the lifting head 411 can be lifted up and down, the magnetic attraction head 412 is slidingly arranged in the lifting head 411 up and down, and after sliding down, it extends out of the bottom end of the lifting head 411 to attract the iron piece 100 downward, or after sliding up, it is retracted into the lifting head 411, the top rod 413 is fixedly arranged at the bottom side of the lifting head 411, so that after the magnetic attraction head 412 slides up, the top rod 413 is used to limit the iron piece 100 from sliding up and press the iron piece 100 downward on the top surface of the magnet group 200, in particular, the top side of the lifting head 411 is connected with a first lifting driving mechanism 416, the first lifting driving mechanism 416 is any existing hydraulic telescopic cylinder for driving the lifting head 411 to lift up and down, the top side of the magnetic attraction head 412 is connected with a second lifting driving mechanism 417, the second lifting driving mechanism 417 is any existing micro telescopic cylinder, and the stroke thereof is smaller than that of the first lifting driving mechanism 416, for driving the magnetic attraction head 412 to slide up and down, a longitudinal channel is formed in the lifting head 411, the longitudinal channel penetrates up and down, for the magnetic attraction head 412 to slide up and down, and a magnet is arranged at the bottom end of the magnetic attraction head 412, which is used to attract the iron piece 100.

[0055] The present application also provides an assembly equipment of Halbach magnetic assembly, which applies the above-mentioned iron piece feeding assembly 400 to assemble the magnet group 200 and the iron piece 100 together to form the magnetic assembly 300.

[0056] The first gripping assembly 405 is shown in detail Figure 1As shown, the magnet group 200 is composed of a first magnet 201 and two second magnets 202, the two second magnets 202 can be attracted to each other and close to each other, the first magnet 201 is located between the two second magnets 202, specifically, the two second magnets 202 are a left magnet 203 and a right magnet 204 respectively, the N pole of the left magnet 203 faces upward, the S pole of the right magnet 204 faces upward, the first magnet 201 is a guide magnet, the N pole of the first magnet 201 faces the right magnet 204, and the S pole of the first magnet 201 faces the left magnet 203, due to the characteristics of the magnetic poles, when the first magnet 201 is located between the two second magnets 202, the lower part of the first magnet 201 moves upward due to the repulsion of the same poles of the lower parts of the two second magnets 202, so that the upper part of the first magnet 201 protrudes from the top surface of the second magnet 202, and then the lower part of the first magnet 201 and the upper part of the two second magnets 202 can be attracted to each other, forming a firm adsorption relationship, and forming the magnet group 200.

[0057] The assembling step of the magnet group 200 of the present application is that the magnet group 200 is assembled by the magnet feeding assembly 500, the magnet feeding assembly 500 is formed with a magnet assembling channel 501, the first magnet 201 is first pushed into the magnet assembling channel 501, and then the two second magnets 202 are pushed into the magnet assembling channel 501 respectively corresponding to the opposite sides of the first magnet 201, so as to limit the mutual adsorption of the two second magnets 202, after the two second magnets 202 are pushed in respectively, the first magnet 201 moves upward so that the upper part of the first magnet 201 protrudes from the top surface of the two second magnets 202, and the two second magnets 202 are respectively adsorbed on the two sides of the lower part of the first magnet 201, forming the magnet group 200 which is adsorbed to each other.

[0058] The magnet assembly 300 is assembled by the magnet group 200 and the iron piece 100, and the assembling step of the magnet assembly 300 of the present application is that the top surface of the first magnet 201 and the top surface of the second magnet 202 are glued in sequence, then the top plate 110 of the iron piece 100 is placed on the top side of the magnet group 200 and is attached to the top surface of the first magnet 201, and the top plate 110 is pressed downward to make the first magnet 201 descend until the iron piece 100 is adsorbed with the second magnet 202 and is fixed by the glue, forming the magnet assembly 300, in the assembling process, since the iron piece 100 and the first magnet 201 and the second magnet 202 can be adsorbed to each other, by pressing the iron piece 100, the mutual approach of the iron piece 100 and the second magnet 202 is promoted, so that the top surface of the second magnet 202 is adsorbed on the top plate 110 of the iron piece 100, and the top surface of the first magnet 201 and the top surface of the second magnet 202 can be automatically leveled.

[0059] Since the first magnet 201 and the two second magnets 202 are in a flush state, the lower part of the first magnet 201 and the lower part of the second magnet 202 repel each other. After the top plate 110 is bonded and fixed to the top surface of the magnet group 200, the lower part of the second magnet 202 has a tendency to move away from the first magnet 201 due to repulsion. In order to ensure the size of the magnet group 200, the outer expansion tendency of the second magnet 202 is limited by the side plate 120 of the iron piece 100. Preferably, during the assembly step of the magnet assembly 300, the iron piece 100 is placed on the top side of the magnet group 200 with the top plate 110 upwards and the side plate 120 downwards, and the side plate 120 of the iron piece 100 is bonded to the side surface of the magnet group 200. Specifically, the dispensing amount of the left magnet 203 and the right magnet 204 is different, and the dispensing amount of the left magnet 203 is greater than that of the right magnet 204. The side plate 120 of the iron piece 100 is close to the outer side surface of the left magnet 203. After the iron piece 100 is pressed down, the glue can overflow between the side plate 120 of the iron piece 100 and the outer side surface of the left magnet 203, and the side plate 120 of the iron piece 100 and the outer side surface of the left magnet 203 are bonded. The assembly of the magnet assembly 300 is completed, and it is not necessary to dispense glue on the outer side surface of the second magnet 202 separately, which saves the process and ensures the size of the magnet group and the structure is more firm.

[0060] The key combination Figures 5-7 As shown, the magnet assembly channel 501 extends transversely, and the opposite two side walls of the magnet assembly channel 501 are respectively formed with a first magnet inlet 502 and a second magnet inlet 503. The first magnet inlet 502 is only for one first magnet 201 to pass through, and the second magnet inlet 503 is only for one second magnet 202 to pass through. The number of the second magnet inlet 503 is two, and the two second magnet inlets 503 are arranged at intervals. After the first magnet 201 is pushed into the magnet assembly channel 501, the first magnet 201 is located between the two second magnet inlets 503. After the left magnet 203 and the right magnet 204 are simultaneously pushed into the magnet assembly channel 501, they are respectively arranged on the opposite sides of the first magnet 201 to combine to form the magnet group 200. One end of the magnet assembly channel 501 is formed with a magnet discharge outlet 504 for discharging the magnet group 200. Specifically, it also includes a first conveying channel 508 and a second conveying channel 509, like Figure 6The first conveying channel 508 is horizontally extended and is arranged in parallel with the magnet assembling channel 501. The first magnets 201 are sequentially arranged in the first conveying channel 508 according to a predetermined N-level orientation, and are sequentially fed. The first conveying channel 508 is communicated with the first magnet inlet 502 through a first discharging channel 510. The first discharging channel 510 is horizontally extended and is perpendicular to the first conveying channel 508. The first discharging channel 510 is provided with a first magnet push rod 511. A suction block is arranged in a side wall of the first discharging channel 510 away from the first conveying channel 508. The suction block is used for sucking the first magnet 201 into the first discharging channel 510. The suction block can be a magnet that can be attracted to the first magnet 201, or can be an iron block, which can attract the first magnet 201. The iron piece 100 and the iron block are both made of existing ferromagnetic materials. After the first magnet 201 enters the first discharging channel 510, the first magnet push rod 511 is extended to push the first magnet 201 from a side of the first magnet 201 away from the first magnet inlet 502, so that the first magnet 201 is pushed into the magnet assembling channel 501 from the first magnet inlet 502.

[0061] In addition, the first magnet push rod 511 and the second magnet push rod 513 are both connected with telescopic cylinders, and the first magnet push rod 511 and the second magnet push rod 513 are driven to slide by telescopic driving of the telescopic cylinders. Figure 7 The second conveying channel 509 is longitudinally extended. The number of the second conveying channels 509 is two. The two second conveying channels 509 are arranged in parallel and are spaced apart. One of the second conveying channels 509 is used for conveying the left magnet 203, and the other of the second conveying channels 509 is used for conveying the right magnet 204. The second magnets 202 are sequentially fed from top to bottom. The second conveying channel 509 is communicated with the second magnet inlet 503 through a second discharging channel 512. The second discharging channel 512 is horizontally extended and is perpendicular to the magnet assembling channel 501. One end of the second discharging channel 512 is communicated with a bottom side of the second discharging channel 512, and the other end is communicated with the second magnet inlet 503. The second discharging channel 512 is provided with a second magnet push rod 513. The second magnet push rod 513 has two push parts (not shown in the figure). The two push parts are spaced apart and are respectively used for pushing the two second magnets 202. After the second magnets 202 are freely fed to the second discharging channel 512, the second magnet push rod 513 is extended to push the second magnets 202 from a side of the second magnets 202 away from the second magnet inlet 503, so that the two second magnets 202 are simultaneously pushed out of the second magnet inlet 503 to the magnet assembling channel 501. The first magnet push rod 511 and the second magnet push rod 513 cannot be magnetically attracted to each other. In addition, the first magnet push rod 511 and the second magnet push rod 513 are both connected with telescopic cylinders, and the first magnet push rod 511 and the second magnet push rod 513 are driven to slide by telescopic driving of the telescopic cylinders.

[0062] Preferably, the bottom side of the second conveying channel 509 is inclined downward and inward, gradually narrowing to the same width as the second discharge channel 512, so that when the second magnet 202 is located above the second conveying channel 509, it can fall freely, and when it falls to the bottom side, the gradually narrowing channel continuously adjusts the position of the second magnet 202 to ensure the accuracy of the position of the second magnet 202.

[0063] In this embodiment, a magnet pushing plate 514 is also slidably arranged above the magnet assembly channel 501. The magnet pushing plate 514 is made of a non-ferromagnetic material and protrudes in the path of upward movement of the first magnet 201, so as to limit the upward movement of the first magnet 201 after the two second magnets 202 are pushed into the opposite sides of the first magnet 201, thereby adjusting the position of the first magnet 201. The magnet pushing plate 514 can slide along the extension direction of the magnet assembly channel 501. The magnet pushing plate 514 is connected to a first telescopic cylinder 515, which is used to drive the magnet pushing plate 514 to slide back and forth. The magnet pushing plate 514 is used to limit the top side of the magnet group 200, so as to limit the upward movement of the first magnet 201, avoiding the first magnet 201 jumping upward when the two second magnets 202 are pushed into the sides of the first magnet 201. The magnet pushing plate 514 also has a pushing part (not shown in the figure), which extends to the side of the magnet group 200 away from the magnet discharge outlet 504, so that when the magnet pushing plate 514 slides towards the magnet discharge outlet 504, the pushing part pushes the magnet group 200 out of the magnet discharge outlet 504.

[0064] In combination with the above Figure 5 As shown, the magnet feeding assembly 500 further comprises a taking plate 505, which slides between the magnet assembly channel 501 and the taking station 4, and is used to convey the magnet group 200. Specifically, the taking plate 505 is slidably arranged on a second linear module 516, which is any existing linear module capable of realizing linear motion. The second linear module 516 is used to drive the taking plate 505 to slide to the magnet assembly channel 501 or to the taking station 4. The top surface of the taking plate 505 is formed with a magnet groove 506, which extends transversely and has the same extension direction as the magnet assembly channel 501. One end of the magnet groove 506 is formed with a magnet inlet 507, so that when the taking plate 505 slides to the magnet assembly channel 501, the magnet inlet 507 is connected to the magnet discharge outlet 504, allowing the magnet group 200 to be discharged into the magnet groove 506. Specifically, the number of magnet grooves 506 is multiple, and the multiple magnet grooves 506 are arranged at intervals along the sliding direction, so that when the taking plate 505 slides to different positions, different magnet grooves 506 are opposite to the magnet discharge outlet 504 of the magnet assembly channel 501.

[0065] In combination with the above Figure 8As shown, the assembly device further comprises a conveying device 600, a jig 700, a dispensing station 1, an upper iron piece station 2, and a pressing station 3. The conveying device 600 is used to sequentially convey the magnet group 200 to the dispensing station 1, the upper iron piece station 2, and the pressing station 3. The conveying device 600 can be any existing conveying structure and is not specifically limited. The jig 700 is used to load the magnet group 200. The number of the jig 700 is multiple. The multiple jigs 700 are sequentially arranged in a head-to-tail manner on the conveying device 600. The taking station 4 is located before the dispensing station 1. The taking station 4 is provided with a second grabbing assembly 41. After the jig 700 is conveyed to the taking station 4, the second grabbing assembly 41 is used to suck and place the magnet group 200 from the magnet feeding assembly 500 to the top surface of the jig 700. Specifically, as shown in Figure 10 As shown, the second grabbing assembly 41 comprises a fourth linear module 42 and a suction head 43. The fourth linear module 42 is any existing linear module capable of realizing linear motion. The suction head 43 is slidingly arranged on the fourth linear module 42. The fourth linear module 42 can drive the suction head 43 to slide between above the taking station 4 and above the taking plate 505. The suction head 43 can be raised and lowered. When lowered, the suction head 43 is close to the taking station 4 or the taking plate 505. The iron rod 44 is movably arranged on the suction head 43. The iron rod 44 is made of ferromagnetic material and can be attracted to the magnet. The iron rod 44 extends longitudinally and can slide up and down relative to the suction head 43. When sliding down, the iron rod 44 extends out of the bottom end of the suction head 43. When sliding up, the iron rod 44 is retracted into the suction head 43. The suction head 43 cannot be attracted to the magnet group 200 and the iron rod 44. The number of the iron rod 44 is two. When the taking plate 505 slides to the taking station 4, the two iron rods 44 extend downward from the bottom side to respectively attract the two second magnets 202. When the two iron rods 44 are retracted into the suction head 43 after the suction head 43 places the magnet group 200 on the top surface of the jig 700, the magnet group 200 is separated from the suction head 43 and falls on the top surface of the jig 700. In addition, the jig 700 comprises a jig main body 702 and a positioning strip 703. The positioning strip 703 is in a sheet shape and is installed on the top surface of the jig main body 702 and is used to attract the magnet group 200. The jig main body 702 is made of non-ferromagnetic material, specifically aluminum alloy material. The positioning strip 703 is made of ferromagnetic material, specifically iron material. The positioning strip 703 is used to place the magnet group 200. After the magnet group 200 is placed on the positioning strip 703, the magnet group 200 can be automatically attracted to the positioning strip 703 to form a firm attraction relationship. The positioning strip 703 is provided in multiple. The multiple positioning strips 703 are parallel and spaced apart along the conveying direction. The number of the positioning strips 703 on each jig 700 is consistent with the number of the magnet grooves 506 on the taking plate 505.

[0066] In this specific embodiment, a dispensing machine 11 is provided at the dispensing station 1. The dispensing machine 11 is located above the dispensing station 1 and can move up and down, descending to approach the top surface of the magnet assembly 200 or rising to move away from the magnet assembly 200, for dispensing adhesive onto the top surface of the magnet assembly 200. Figure 11 As shown, the dispensing machine 11 is connected to the third linear module 12. The third linear module 12 is any existing linear module capable of linear motion. The third linear module 12 is used to drive the dispensing machine 11 to approach or move away from the magnet group 200 so that it can dispense glue to the first magnet 201 and the second magnet 202 respectively.

[0067] In this specific embodiment, the first linear module 410 of the first gripping component 405 extends laterally between the flip plate 404 and the upper iron part station 2. When the first linear module 410 drives the lifting head 411 to slide above the flip plate 404, the lifting head 411 descends, and the magnetic suction head 412 slides down from the bottom of the lifting head 411, adsorbing the top plate 110 of the iron part 100, so that the iron part 100 moves with the top plate 110 on top and the side plate 120 facing down. When the first linear module 410 drives the lifting head 411 to slide above the upper iron part station 2, the magnetic suction head 412 descends until the top plate 110 of the iron part 100 is attached to the magnetic suction head. On the top surface of the iron assembly 200, the magnetic head 412 slides upward and retracts into the lifting head 411. The top rod 413 presses the iron part 100 down onto the top surface of the magnet assembly 200. Since the iron part 100 is made of ferromagnetic material, it can magnetically attract each other with the second magnet 202. Then, during the process of pressing down the top plate 110, the first magnet 201 moves down until the top plate 110 and the top surface of the second magnet 202 attract each other and are bonded and fixed. The pressing station 3 is equipped with a first extrusion assembly 31. The first extrusion assembly 31 is used to extrude and align the outer periphery of the magnetic assembly 300, so that the side plate 120 of the iron part 100 is bonded and fixed to the side of the magnet assembly 200.

[0068] Key points combined Figures 13-14 As shown, it also includes an extrusion station 6, located between the material handling station 4 and the dispensing station 1. The extrusion station 6 is equipped with an alignment plate 61, a pushing assembly 62, and a second extrusion assembly 63. The alignment plate 61 is located on one side of the extrusion station 6 along the conveying direction. The pushing assembly 62 extends to both sides of the extrusion station 6 along the conveying direction, used to push and abut the fixture 700 against the alignment plate 61, or to push and reset the fixture 700 so that it can be conveyed along the conveying direction. After the fixture 700 abuts against the alignment plate 61, the second extrusion assembly 63 aligns the outer periphery of the magnet assembly 200. The second extrusion assembly 63 includes a push plate 631 and a clamp 632. The push plate 631 is capable of lateral movement, such as... Figure 14As shown, the top end of the jig 700 protrudes a boss 701, specifically, the boss 701 is arranged on the top side of the jig body 702 and located on one side of the positioning strip 703. The push plate 631 can slide horizontally, and the sliding direction is perpendicular to the conveying direction of the jig 700. After the jig 700 is placed on the conveying device 600, the push plate 631 is opposite to the boss 701, and the push plate 631 pushes one end of the magnet assembly 200 along the side perpendicular to the conveying direction, so that the other end of the magnet assembly 200 abuts against the boss 701. The chuck 632 can move horizontally along the conveying direction and can rise and fall. When the chuck 632 moves horizontally to the top of the magnet assembly 300 and then falls, the chuck 632 is used to clamp the opposite sides of the magnet assembly 200 along the conveying direction, so that the magnet assembly 200 is squeezed to be flush around. In the embodiment, the first squeezing assembly 31 and the second squeezing assembly 63 have the same structure and also include the push plate 631 and the chuck 632. Specifically, as shown in the figure, Figure 12 As shown, the chuck 632 is composed of two squeezing heads 32. The two squeezing heads 32 can approach or move away from each other. When the two squeezing heads 32 approach each other, the opposite sides of the magnet assembly 300 are clamped, and the magnet assembly 300 is squeezed to be flush. When the two squeezing heads 32 move away from each other, the magnet assembly 300 is released. In addition, the working process of the first squeezing assembly 31 is the same as that of the second squeezing assembly 63, and details are not described here.
