Technical Field
[0001] This utility model relates to the field of auxiliary equipment for 3C product processing, specifically an automatic magnet disassembly and assembly device. Background Technology
[0002] In the production and assembly of 3C products, magnets are key components for realizing the magnetic attraction function of equipment, and their installation quality directly affects product performance. As 3C products become thinner, lighter, and more precise, the assembly precision requirements between magnets and product casings continue to increase. In the early days, manual positioning and installation of magnets were mostly carried out. Subsequently, semi-automatic assembly equipment was gradually developed, which uses jigs to assist in positioning. However, the disassembly process still relies on manual operation for a long time.
[0003] Because 3C product casings often have undercut grooves on their side walls to improve structural stability, manual removal using pry bars is difficult to control precisely in terms of force direction and intensity, easily scratching the casing surface or damaging the undercut groove structure, resulting in a high product scrap rate. Furthermore, manual removal requires prying each magnet individually; for products with multiple magnets, this is time-consuming, inefficient, and the repetitive nature of the operation significantly increases the labor intensity of workers, failing to meet the requirements of disassembly efficiency and product yield in mass production. In addition, some magnets are fixed inside the casing with glue; before manual removal, the glue must be manually heated to melt it. Precise control of heating temperature and time is difficult, resulting in either insufficient melting of the glue leading to removal difficulties or overheating damaging internal components, further limiting the applicability of manual removal methods. Therefore, there is a strong need to design a highly automated magnet disassembly and assembly device with a high degree of automation and high disassembly efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic magnet disassembly and assembly device, which has the advantages of high automation, high disassembly efficiency, avoidance of product scratches and scrapping, and reduction of labor intensity. It solves the problems of low efficiency, high product scrap rate, and high labor intensity of existing manual disassembly methods.
[0005] To achieve the aforementioned goals of high automation, high dismantling efficiency, prevention of product scratches and scrapping, and reduction of labor intensity, this utility model provides the following technical solution: an automatic magnet dismantling and assembly device, comprising a main board module and a motion module. The main board module includes a fixture frame, with the main board mounted on the top inner side of the fixture frame, and an XY-direction positioning block provided on the top of the main board. Heating and centering cylinders are symmetrically connected to the inner sidewall of the fixture frame, and a rotary pressing cylinder is connected to the top of the fixture frame. The motion module includes a mounting frame, which is connected to the outer sidewall of the fixture frame of the main board module. A pull-back cylinder, an upper-lift cylinder, and a side-push cylinder are sequentially connected to the mounting frame. The output end of the pull-back cylinder is connected to a sliding seat, the upper-lift cylinder is connected to the bottom of the sliding seat, and the output end of the side-push cylinder is connected to a magnetic claw, which is disposed on the side of the fixture frame.
[0006] Preferably, the output end of the heating and centering cylinder is connected to an inclined groove, a pin is slidably connected in the inclined groove, and a heating copper block is connected to the end of the pin away from the inclined groove. The heating copper block is located on both sides of the positioning block in the XY direction.
[0007] Preferably, the output end of the rotary clamping cylinder is connected to a pressure claw, which is located directly above the positioning block in the XY direction.
[0008] Preferably, a suction cup is also connected to the top of the motherboard, and the suction cup is located below the positioning block in the XY direction.
[0009] Preferably, the output end of the top cylinder is connected to a support seat, and the side cylinder is symmetrically connected to the top of the support seat.
[0010] Preferably, the inner sidewall of the fixture frame is also connected to a pullback limiting block, which is located on the movement path of the sliding seat, and the sidewall and bottom of the pullback limiting block are provided with buffer pads.
[0011] Preferably, a flanged linear bearing is connected to the mounting bracket, and a guide rod is slidably connected to the inner ring of the flanged linear bearing.
[0012] Preferably, the top of the XY direction positioning block is provided with a positioning groove, and the inner sidewall of the positioning groove is provided with anti-slip texture.
[0013] Preferably, the motherboard module and the motion module are mounted on a workbench, and an indicator is also mounted on the workbench.
[0014] Preferably, the bottom of the workbench is connected to a support leg, and one side of the support leg is equipped with a caster wheel.
[0015] Compared with the prior art, the present invention provides an automatic magnet assembly and disassembly device, which has the following beneficial effects: 1. This automatic magnet assembly / disassembly equipment achieves precise positioning and fixation of products in the X, Y, and Z directions through a combination structure of XY-direction positioning blocks, rotary clamping cylinders, clamping claws, and suction cups in the main board module. Compared to manual hand-held fixation, this structure achieves a positioning accuracy of ±0.1mm, avoiding magnet assembly / disassembly deviations caused by product misalignment during operation. Simultaneously, the heating and centering cylinder, via an inclined groove, drives a heating copper block to clamp the product, ensuring uniform clamping force and directly heating the magnet fixing adhesive through the heating copper block. This increases heating efficiency by 3 times compared to manual hand-held heating tools, preventing problems such as adhesive overheating and carbonization or insufficient heating and failure to melt.
[0016] 2. This automatic magnet assembly and disassembly equipment achieves automatic movement of the magnet claws in three directions: front-back, up-down, and left-right, through the coordinated operation of the pull-back cylinder, top-top cylinder, side-push cylinder, and magnet claws in the motion module. The pull-back cylinder drives the claws to approach or move away from the product, the top-top cylinder adjusts the height of the claws to match the position of the product's undercut groove, and the side-push cylinder drives the claws to clamp or release the magnets. The entire process requires no manual intervention, improving efficiency by more than 5 times compared to manual assembly and disassembly. Furthermore, the design of the magnetic claw's slot and elastic rubber layer ensures that the magnets are firmly clamped while avoiding damage to them. At the same time, the claw's movement path is precisely controlled by the cylinder, preventing scratches on the product's undercut groove or outer surface, reducing the product scrap rate to below 0.5%.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] As shown in Figure 2 and Figure 3 An automatic magnet assembly / disassembly device includes a main board module 1 and a motion module 2. The main board module 1 includes a fixture frame 11, with a main board 12 mounted on the top inner side of the fixture frame 11. An XY-direction positioning block 15 is provided on the top of the main board 12. Heating and centering cylinders 19 are symmetrically connected to the inner wall of the fixture frame 11, and a rotary pressing cylinder 13 is connected to the top of the fixture frame 11. The motion module 2 includes a mounting frame 21, which is connected to the outer wall of the fixture frame 11 of the main board module 1. A pull-back cylinder 28, an upward-lifting cylinder 24, and a side-push cylinder 26 are sequentially connected to the mounting frame 21. The output end of the pull-back cylinder 28 is connected to a sliding seat 210, the upward-lifting cylinder 24 is connected to the bottom of the sliding seat 210, and the output end of the side-push cylinder 26 is connected to... The device is equipped with a magnetic pull claw 27, which is located on the side of the fixture frame 11. The equipment achieves automated disassembly and assembly of the magnet through the linkage of the pull-back cylinder 28, the top-lifting cylinder 24, and the side-pushing cylinder 26, without the need for manual intervention, which significantly improves production efficiency. The XY-direction positioning block 15 on the top of the main board 12 can precisely limit the position of the magnet in the horizontal direction to avoid installation deviation. The heating and centering cylinder 19 softens the adhesive material around the magnet by heating, and at the same time, the centering cylinder applies pressure symmetrically from both sides to ensure that the magnet remains centered during the heating process and prevents displacement caused by thermal expansion and contraction. The rotating clamping cylinder 13 on the top of the fixture frame 11 can press down vertically to fix the position of the magnet and prevent displacement due to vibration or external force during disassembly and assembly.
[0021] like Figure 6As shown, the output end of the heating and centering cylinder 19 is connected to an inclined groove 110. A pin 111 is slidably connected within the inclined groove 110. The end of the pin 111 away from the inclined groove 110 is connected to a heating copper block 17, which is located on both sides of the XY direction positioning block 15. The inclined groove 110 is designed to convert the linear motion of the cylinder into the inclined displacement of the pin 111, enabling bidirectional synchronous movement of the heating copper block 17 within a limited space. The heating copper block 17 is directly embedded in both sides of the XY direction positioning block 15, closely fitting the magnet mounting position, reducing heat loss, and avoiding occupying additional operating space. The two heating copper blocks 17 move synchronously inward or outward along the inclined groove 110 under the drive of the cylinder, always maintaining symmetrical clamping of the magnet, preventing the magnet from shifting or tilting due to uneven force on one side. The angle design of the inclined groove 110 can compensate for the cylinder stroke error, ensuring that the heating copper block 17 always maintains parallel contact with the magnet surface during movement, improving heating uniformity.
[0022] like Figure 2 and Figure 5 As shown, the output end of the rotary clamping cylinder 13 is connected to a clamping claw 14, which is located directly above the XY-direction positioning block 15. The XY-direction positioning block 15 restricts the movement of the magnet in the horizontal plane, while the rotary clamping cylinder 13 drives the clamping claw 14 to press down vertically from directly above, forming a three-dimensional positioning system to avoid poor contact or functional failure caused by tilting or offset. When the clamping claw 14 presses down, its contact surface matches the shape of the top of the magnet, and the slight tilt of the magnet is automatically corrected by mechanical limit, achieving self-centering and further improving the positioning accuracy.
[0023] like Figure 2 As shown, a suction cup 16 is also connected to the top of the motherboard 12. The suction cup 16 is located below the XY direction positioning block 15. The XY direction positioning block 15 controls the horizontal position of the magnet by side limiting, while the suction cup 16 adsorbs the bottom of the magnet from below and uses vacuum suction to vertically tighten the magnet, completely eliminating the gap between the magnet and the mounting position, and further improving the positioning accuracy.
[0024] like Figure 4 As shown, the output end of the upper cylinder 24 is connected to the support seat 29, and the side push cylinder 26 is symmetrically connected to the top of the support seat 29. The upper cylinder 24 drives the support seat 29 to rise, accurately pushing the magnet or workpiece to the target position, eliminating sinking or offset caused by gravity, and ensuring vertical positioning accuracy. The symmetrically arranged side push cylinders 26 apply thrust from both sides simultaneously. Through mechanical limit or pressure control, the magnet or workpiece is accurately aligned in the horizontal plane to form a three-dimensional positioning system, further improving positioning accuracy. The actions of the upper cylinder 24 and the side push cylinder 26 are controlled independently to avoid mutual interference between vertical and horizontal forces. For example, the side push cylinder 26 can remain stationary during the lifting process to prevent the magnet from tilting due to horizontal thrust.
[0025] like Figure 2 and Figure 7 As shown, a pullback limiting block 25 is also connected to the inner wall of the fixture frame 11. The pullback limiting block 25 is located on the movement path of the sliding seat 210. The side wall and bottom of the pullback limiting block 25 are provided with buffer pads 251. The pullback limiting block 25 is fixed to the inner wall of the fixture frame 11 and is located directly in front of the preset movement endpoint of the sliding seat 210. When the sliding seat 210 exceeds the target position due to inertia or control system error, the limiting block forcibly stops its movement by physical blocking, avoiding hard collision with the fixture frame 11 or other components. The position of the limiting block is fixed and highly accurate, which can ensure that the sliding seat 210 stops at the same position each time, improving product consistency. The buffer pads 251 on the side wall of the limiting block can absorb the horizontal impact force of the sliding seat 210, preventing scratches on the surface of the sliding seat 210 or deformation of the limiting block itself due to repeated impacts. The bottom buffer pads 251 reduce the impact force through elastic deformation for vertical impacts, protecting the bottom structure of the sliding seat 210 and the fixture frame 11.
[0026] like Figure 4 As shown, a flanged linear bearing 22 is connected to the mounting bracket 21, and a guide rod 23 is slidably connected to the inner ring of the flanged linear bearing 22. The flanged linear bearing 22 uses balls or rollers as rolling elements, and the clearance between the inner ring and the guide rod 23 is extremely small, which can strictly limit the movement direction of the guide rod 23 and prevent it from wobbling or tilting, thus meeting the requirements of high-precision assembly. The flange is fastened to the mounting bracket 21 by bolts to form a rigid connection, which prevents the linear bearing from shifting or loosening due to force during movement, further ensuring the guiding accuracy. The linear bearing significantly reduces energy loss through the rolling contact between the rolling elements and the guide rod 23.
[0027] like Figure 3 As shown, the top of the positioning block 15 in the XY direction is provided with a positioning groove 18, and the inner wall of the positioning groove 18 is provided with anti-slip texture. The V-shaped, U-shaped or rectangular structure of the positioning groove 18 can form multi-directional constraints on the positioned part. The anti-slip texture on the inner wall of the groove can increase the micro-roughness of the contact surface, further restrict small displacements, and avoid positioning offset caused by vibration or inertia.
[0028] like Figure 1 As shown, the motherboard module 1 and motion module 2 are set on the workbench 4, and the workbench 4 is also equipped with an indicator 3; the motherboard module 1, motion module 2 and indicator 3 are arranged in layers or sections on the workbench 4 to make full use of vertical space and reduce the floor area.
[0029] like Figure 1As shown, the bottom of the workbench 4 is connected to a support leg 41, and a caster wheel 42 is provided on one side of the support leg 41. The support leg 41 is fixed to the bottom of the workbench 4 by bolts or welding to form a stable four-corner support structure. The caster wheel 42 is connected to one side of the support leg 41 by a bearing, which can achieve 360° free rotation in the horizontal direction, so that the equipment can easily turn and move in a narrow space. The caster wheel 42 is equipped with a brake device. When the equipment moves to the target position, stepping on the brake can fix the wheel and prevent the equipment from sliding during use.
[0030] Working principle: Place the iPad casing or other product to be fitted with magnets into the positioning groove 18 of the XY direction positioning block 15, ensuring the product fits against the inner wall of the groove, and the device starts; the controller controls the heating and centering cylinder 19 to start, the piston rod pushes the inclined groove 110 forward, the inclined groove 110 drives the heating copper block 17 to move inward through the pin 111 until the high-temperature resistant silicone pad of the heating copper block 17 fits against the side wall of the product, achieving product clamping in the X direction; then, the rotary clamping cylinder 13 starts, the piston rod first extends downward and then rotates 90°, driving the clamping claw 14 to clamp the top of the product, achieving product clamping in the Z direction; finally, the heating copper block 17 begins to press... Heat is transferred to the adhesive fixing the magnets on the side wall of the product, with the heating temperature controlled at 100℃ and heated continuously for 5 minutes to ensure the adhesive is completely melted. After heating, the pull-back cylinder 28 is activated, and the piston rod pushes the sliding seat 210 forward. The sliding seat 210 drives the upper lifting cylinder 24, the support seat 29, the side pushing cylinder 26, and the magnetic claw 27 to move forward together until the sliding seat 210 touches the pull-back limit block 25. Then, the upper lifting cylinder 24 is activated, and the piston rod drives the support seat 29, the side pushing cylinder 26, and the magnetic claw 27 to move downward until the magnetic claw 27 aligns with the undercut groove on the side wall of the product. Then, the pull-back cylinder 28 is activated in the reverse direction, and the piston... The rod drives the sliding seat 210 and subsequent components to move backward, causing the magnetic claw 27 to extend into the product's undercut groove until the pull-back cylinder 28 returns to its original position. Then, the side-push cylinder 26 is activated, and the piston rod pushes the magnetic claw 27 inward, causing its slot to engage the magnet on the product's side wall. After the side-push cylinder 26 reaches its position, the pull-back cylinder 28 is activated in the reverse direction, causing the piston rod to drive the sliding seat 210 and magnetic claw 27 backward. The magnet separates from the product under the pulling force of the claw, completing magnet removal. After magnet removal, the side-push cylinder 26 is activated in the reverse direction, and the piston rod drives the magnetic claw 27 to move outward back to its original position. Subsequently, the pull-back cylinder 28 is activated in the forward direction. The sliding seat 210 and the pull claw move forward; the upper cylinder 24 starts in reverse, causing the bearing seat 29 and the pull claw to move upward and return to their original positions; the pull-back cylinder 28 starts in reverse again, causing the pull claw to move backward away from the product; then, the heating and centering cylinder 19 starts in reverse, causing the heating copper block 17 to move outward and release the product in the X direction; the rotating clamping cylinder 13 starts in reverse, the piston rod rotates 90° and then retracts upward, causing the clamping claw 14 to release the product in the Z direction; the external vacuum pump stops working, and the suction cup 16 disconnects the vacuum; finally, the operator takes out the product after the magnet has been removed, and a set of magnet removal operations is completed; if it is necessary to continue the operation, the above steps can be repeated.
[0031] In summary, this automatic magnet assembly / disassembly equipment achieves precise product fixation through the XY direction positioning block 15, heating and centering cylinder 19, rotating and clamping cylinder 13, and suction cup 16 in the main board module 1, and efficiently melts the adhesive through the heating copper block 17; the magnet claws 27 are driven by multiple sets of cylinders in the motion module 2 to automatically complete the magnet assembly / disassembly; it effectively solves the problems of low efficiency, easy scratching of products, and high labor intensity of manual assembly / disassembly, improves the efficiency and quality of magnet assembly / disassembly for 3C products, and reduces production costs and operational risks.
