Description

Technical Field

[0001] This utility model relates to the field of disassembly tooling, and in particular to a magnet recycling device for pressure holding tooling and a production line using the device. Background Technology

[0002] In the manufacturing of injection molding pressure holding fixtures, magnets are used extensively as key functional components (such as for positioning and adsorption). Due to the strict lifespan control of pressure holding fixtures, they must be scrapped and replaced after reaching their service life. This results in a large number of usable magnets being discarded along with the used pressure holding fixtures, leading to a significant waste of magnets.

[0003] In related technologies, a magnet disassembly mechanism has been proposed to achieve magnet disassembly. This mechanism includes a magnet ejection fixture and a cylinder connected to it. During disassembly, the cylinder drives the magnet ejection fixture to move, pressing the magnet on the substrate to separate it from the substrate. However, during the pressing process of the magnet ejection fixture, the pressure-holding fixture is easily misaligned by external forces, causing it to detach from its original pressing position. This leads to uneven force on the magnet, resulting in breakage. The external force is the rebound force generated by the material of the pressure-holding fixture after the initial pressing pressure. Furthermore, related technologies have also proposed a magnet disassembly mechanism including a heating mechanism and an ejection mechanism. The heating mechanism is suitable for heating the product to melt the adhesive bonded to the magnet, and the ejection mechanism is suitable for ejecting the magnet. While these structures can achieve magnet disassembly, their design is complex, and the heating mechanism requires additional power, resulting in high operating costs.

[0004] This invention solves the above problems through modular design, realizing an integrated operation of rapid magnet positioning, ejection, and collection. The structure is simple and the disassembly efficiency is high. Utility Model Content

The guide portion slides relative to the connecting plate along the first direction. An elastic element is installed between the pressure-holding head and the connecting plate. Before the pressure-holding head is pressed, the distance between the end of the pressure-holding head and the fixed base is less than the distance between the end of the magnet push rod and the fixed base; after the pressure-holding head is pressed, the force of the pressure-holding head acting on the pressure-holding fixture is greater than the elastic force of the elastic element, the elastic element is compressed, and the connecting plate moves relative to the guide portion toward the direction closer to the fixed base, so as to drive the magnet push rod to push out the magnet on the pressure-holding fixture of the magnet to be removed; A magnet collecting assembly, along the first direction, is positioned opposite the magnet falling channel to collect magnets falling from the magnet falling channel.

[0007] According to some embodiments of the present invention, a first slide rail is provided on the top of the fixed base, and the workpiece positioning fixture is slidably installed on the first slide rail; The magnet recycling device further includes a second driving cylinder, which is located on one side of the fixed base. One end of the second driving cylinder is provided with a second driving part, which is connected to the workpiece positioning fixture to drive the workpiece positioning fixture to reciprocate along a second direction, which is perpendicular to the first direction.

[0008] According to some embodiments of the present invention, a top rod fixing block is installed on the side of the connecting plate near the fixed base, and the magnetic top rod is installed on the side of the top rod fixing block near the fixed base, and the magnetic top rod and the fixing block are detachably connected.

[0009] According to some embodiments of the present invention, a bushing is installed in the through hole through which the guide portion penetrates the connecting plate, and the guide portion is slidably installed in the bushing.

[0010] The elastic element is a spring, with one end of the spring connected to the bushing and the other end connected to the end of the pressure-holding head.

[0011] According to some embodiments of this utility model, pressure-holding uprights are respectively provided at the opposite two side edges of the top of the connecting plate; the top of the pressure-holding uprights is fixedly connected to the fixing plate.

[0012] According to some embodiments of the present invention, the magnet collecting assembly includes a magnet collecting box located below the magnet falling channel and a magnet collecting guide box disposed above the magnet collecting box and having a hollow interior; the top of the interior space of the magnet collecting guide box corresponds to the magnet falling channel, and the bottom corresponds to the interior of the magnet collecting box.

[0013] According to some embodiments of the present invention, the internal channel of the magnet collecting guide box includes a connected inlet channel and an outlet channel; the side wall of the outlet channel is set at an angle to the extending direction of the inlet channel to form a buffer zone.

[0014] According to some embodiments of this utility model, bearing fixing blocks are provided around the bottom of the magnet collecting box; bearings are installed on the bearing fixing blocks; The bracket is provided with a support base plate, and the support base plate is provided with a second slide rail; The bearing is rotatably mounted in the second slide rail.

[0015] The beneficial effects of this utility model are as follows: The present invention includes a magnet ejection assembly, a magnet collection assembly, and a first drive cylinder for generating driving force. The magnet ejection assembly includes a fixed plate mounted on the first driving unit and a connecting plate connected to the fixed plate and located near the fixed base. The connecting plate and the fixed plate are spaced apart to form an accommodating space. A pressure-holding head and at least one magnet push rod are mounted on the side of the connecting plate near the fixed base. The magnet push rod is adapted to face the magnet on the pressure-holding fixture. The first driving cylinder can drive the magnet push rod to move along the first direction. The pressure-holding head has a guide portion that passes through the connecting plate and extends into the accommodating space. The guide portion slides relative to the connecting plate along the first direction. An elastic element is installed between the pressure-holding head and the connecting plate. Before the pressure-holding head is pressed, the distance between the end of the pressure-holding head and the fixed base is less than the distance between the end of the magnet rod and the fixed base. During operation, the fixed plate moves closer to the pressure-holding fixture. This structure ensures that the end of the pressure-holding head contacts the pressure-holding fixture before the end of the magnet rod, thus ensuring the priority of the pressure-holding head's operation. After the pressure-holding head is pressed, the force exerted by the pressure-holding head on the pressure-holding fixture is greater than the elastic force of the elastic element, and the elastic element is compressed. Before the magnet rod presses against the magnet on the pressure-holding fixture, the pressure-holding head contacts the pressure-holding fixture first and receives a reaction force. The elastic element is compressed and exerts pressure on the pressure-holding fixture. Under this pressure, the position of the pressure-holding fixture is ensured, further ensuring the accuracy of the magnet rod's pressing operation on the magnet. The elastic pressure-holding mechanism ensures the stable positioning of the magnet rod and the magnet in the pressure-holding fixture, ensuring zero damage during disassembly. As the connecting plate moves relative to the guide portion towards the fixed base, it can drive the magnet rod to push out the magnet from the pressure-holding fixture containing the magnet to be disassembled.

[0016] The present invention proposes a second technical solution: a production line for automatically disassembling pressure-holding tooling magnets, comprising: The pressure-holding tooling magnet recycling device is the first technical solution proposed in this utility model. A feeding hopper, wherein a pressure-holding fixture is provided inside which multiple magnets to be disassembled are stacked; A handling robot, the handling robot having a robotic arm for gripping the pressure-holding fixture in the feeding bin, the robotic arm being used to place the pressure-holding fixture containing the magnet to be removed into the workpiece positioning slot; The unloading hopper is provided with multiple storage positions for storing the pressure-holding fixtures for disassembled magnets. The robotic arm grabs the pressure-holding fixtures for disassembled magnets from the workpiece positioning slot and places them in the corresponding storage positions.

[0017] According to some embodiments of the present invention, in an AGV transport vehicle, the unloading bin is placed inside the AGV transport vehicle. After the unloading bin is filled with the pressure-holding fixture for disassembling the magnets, the AGV transport vehicle is used to transport the unloading bin to a storage warehouse.

[0018] The beneficial effects of this utility model are as follows: The production line for automatically disassembling pressure-holding fixture magnets according to this utility model includes a pressure-holding fixture magnet recycling device (adopting a first technical solution), a feeding hopper, a discharging hopper, and a handling robot. The handling robot moves the pressure-holding fixture with undisassembled magnets from the feeding hopper to the pressure-holding fixture magnet recycling device. After disassembly, the handling robot moves the pressure-holding fixture with disassembled magnets from the pressure-holding fixture magnet recycling device to the discharging hopper. Therefore, the production line constructed based on the pressure-holding fixture magnet recycling device of this utility model achieves integrated operation of rapid magnet positioning, ejection, and collection due to the accurate positioning and disassembly of the pressure-holding fixture magnet recycling device, thereby improving the working efficiency of the production line.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] Figure 1 , Figure 2 and Figure 3 As shown, according to the first aspect of this utility model, a pressure-holding tool magnet recycling device is disclosed, comprising: Support 1; Fixed base 4, connected to the support 1, the fixed base 4 is equipped with a workpiece positioning fixture 44; the workpiece positioning fixture 44 is provided with a workpiece positioning groove 441 suitable for placing a pressure holding fixture for the magnet to be removed, the pressure holding fixture for the magnet to be removed refers to the pressure holding fixture for the magnet to be removed; the workpiece positioning groove 441 is provided with a magnet falling channel 442 that penetrates the workpiece positioning fixture 44 along a first direction (e.g., vertical direction); First driving cylinder 5, the first driving cylinder 5 is fixed to the support 1, the first driving cylinder 5 has a first driving part 51 that reciprocates along the first direction; Magnet ejection assembly 2, including a fixed plate 21 installed on the first driving part 51, connected to the fixed plate 21 and abutting against A connecting plate 22 is located near the fixed base 4; the connecting plate 22 and the fixed plate 21 are spaced apart to form an accommodating space 27; a pressure-holding head 24 and at least one magnetic push rod 25 are installed on the side of the connecting plate 22 near the fixed base 4, the magnetic push rod 25 is adapted to face the magnet on the pressure-holding fixture, and the first driving cylinder 5 can drive the magnetic push rod 25 to move along the first direction; the pressure-holding head 24 has a guide portion 241, the guide portion 241 penetrates the connecting plate 22 and extends into the accommodating space 27; the guide portion 241 slides relative to the connecting plate 22 along the first direction; an elastic element 26 is installed between the pressure-holding head 24 and the connecting plate 22. Before the pressure holding head 24 is pressed, the distance between the end of the pressure holding head 24 and the fixed base 4 is less than the distance between the end of the magnet push rod 25 and the fixed base 4; after the pressure holding head 24 is pressed, the force of the pressure holding head 24 acting on the pressure holding fixture is greater than the elastic force of the elastic member 26, the elastic member 26 is compressed, and the connecting plate moves relative to the guide portion toward the direction closer to the fixed base, so as to drive the magnet push rod to push out the magnet on the pressure holding fixture of the magnet to be removed; A magnet collecting component 3, along the first direction, is positioned opposite the magnet falling channel 442 to collect magnets falling from the magnet falling channel 442.

[0022] During operation, the pressure-holding fixture for disassembling magnets is placed in the workpiece positioning groove 441 of the workpiece positioning fixture 44, with the exposed magnets on both sides of the pressure-holding fixture corresponding to the positions of the magnet push rod 25. The first drive cylinder 5 drives the first drive part 51 to extend along a first direction, thereby driving the pressure-holding head 24 and the magnet push rod 25, which are mounted on the fixed plate 21, to move. The first direction referred to here is... Figure 1 As shown in the vertical direction. During the movement, the end of the pressure-holding head 24 first contacts the pressure-holding fixture; as the first driving part 51 continues to extend, the force of the pressure-holding head 24 acting on the pressure-holding fixture is greater than the elastic force of the elastic member 26, and the elastic member 26 is compressed. At this time, the compressed elastic member 26 drives the end of the pressure-holding head 24 to exert pressure on the pressure-holding fixture, thereby achieving the positioning of the pressure-holding fixture and preventing the pressure-holding fixture from being misaligned by external forces. As the first driving part 51 continues to extend along the first direction, the connecting plate can move relative to the guide part toward the direction closer to the fixed base, thereby driving the end of the magnet rod 25 to contact the pressure-holding fixture and squeeze its magnet. The squeezed magnet is removed from the pressure-holding fixture and falls into the magnet collecting assembly 3 through the magnet falling channel 442.

[0023] See Figure 1 and Figure 3 In one specific embodiment, the magnet recycling device further includes a second driving cylinder 42, which is disposed on one side of the fixed base 4. One end of the second driving cylinder 42 is provided with a second driving part, which is connected to the workpiece positioning fixture 44 to drive the workpiece positioning fixture 44 to reciprocate along a second direction, which is perpendicular to the first direction.

[0024] The fixed base 4 has a first slide rail 41 on its top, and the workpiece positioning fixture 44 is slidably installed in the first slide rail 41. During operation, the workpiece positioning fixture 44 is driven by the second drive cylinder 42 to slide back and forth in the first slide rail 41. The direction of movement is a second direction perpendicular to the first direction, that is, the second direction can be... Figure 1 As shown in the horizontal direction. The movable setting of the workpiece positioning fixture 44 allows for position adjustment to match the setting of the magnetic push rod 25, achieving precise positioning of the magnet position on the pressure holding fixture and the magnetic push rod 25 position, ensuring the processing accuracy of the equipment.

[0025] In one specific embodiment, a top rod fixing block is installed on the side of the connecting plate 22 near the fixed base 4, and the magnetic top rod 25 is installed on the side of the top rod fixing block near the fixed base 4.

[0026] The push rod fixing block is fixed to the connecting plate 22, and the magnetic push rod 25 is fixedly installed on the push rod fixing block 28. The push rod fixing block 28 brings the root of the magnetic push rod 25 close to the workpiece positioning fixture 44, shortening the length of the magnetic push rod 25 while ensuring its pressing operation, thereby improving the strength and service life of the components. Optionally, the magnetic push rod and the fixing block are detachably connected, allowing the number and position of the magnetic push rods to be selected according to different models of pressure-holding fixtures, thus improving the applicability of the pressure-holding fixture magnet recovery device.

[0027] See Figure 2 In one specific embodiment, a bushing 221 is installed in the through hole through which the guide portion 241 penetrates the connecting plate 22, and the guide portion 241 is slidably installed in the bushing 221. The elastic element 26 is a spring, one end of which is connected to the bushing 221, and the other end is connected to the end of the pressure-holding head 24.

[0028] Specifically, the bushing 221 is fixedly installed in the through hole through which the guide portion 241 passes. The bushing 221 increases the axial support distance for the guide portion 241, ensuring the guiding support strength for the guide portion 241. Simultaneously, the inner surface of the bushing 221 can be precision machined or coated with lubricant to increase the lubrication effect between components. Besides springs, the elastic element 26 can also be made of other elastic materials, such as rubber sleeves.

[0029] In one specific embodiment, pressure-holding uprights 23 are respectively provided at the opposite two edges of the top of the connecting plate 22; the top of the pressure-holding uprights 23 is fixedly connected to the fixing plate 21.

[0030] The pressure-holding plates 23 are arranged opposite each other, which allows the connecting plate 22 to achieve force balance after being pressed by the spring, thus avoiding the reduction of the connection strength between the parts due to uneven force.

[0031] See Figure 1 and Figure 4 In one specific embodiment, the magnet collecting assembly 3 includes a magnet collecting box 31 located below the magnet falling channel 442 and a magnet collecting guide box 32 disposed above the magnet collecting box 31 and having a hollow interior; the top of the interior space of the magnet collecting guide box 32 corresponds to the magnet falling channel 442, and the bottom corresponds to the interior of the magnet collecting box 31.

[0032] The magnet collecting guide box 32 is placed on the magnet collecting box 31. During operation, the magnets that are squeezed out need to fall into the magnet collecting box 31 through the magnet falling channel 442. The magnet collecting guide box 32 provides the above-mentioned channel. By guiding and gathering the falling magnets, the magnets are efficiently collected, and the magnets are prevented from falling outside the magnet collecting box 31.

[0033] See Figure 1 , Figure 4 and Figure 5 In one specific embodiment, the internal channel of the magnet collecting guide box 32 includes a connected inlet channel 321 and an outlet channel 322; the side wall of the outlet channel 322 is set at an angle to the extending direction of the inlet channel 321 to form a buffer zone.

[0034] The inlet of the feeding channel 321 corresponds to the magnet drop channel 442, and the outlet of the discharge channel 322 corresponds to the inside of the magnet collection box 31. During operation, after the magnet enters the buffer zone through the feeding channel 321, it will collide with the side wall of the discharge channel 322, thereby reducing the kinetic energy of the falling magnet and thus playing a buffering role to prevent the magnet from being damaged due to the large impact of falling.

[0035] See Figure 1 , Figure 2 and Figure 6 In one specific embodiment, the bottom of the magnet collecting box 31 is provided with bearing fixing blocks 33 around its perimeter; the bearing fixing blocks 33 are equipped with bearings 34; the bracket 1 is provided with a supporting base plate 35, and the supporting base plate 35 is provided with a second slide rail 36; the bearings 34 are rotatably installed in the second slide rail 36.

[0036] The extension direction of the second slide rail 36 corresponds to the second direction, that is, the same direction as the movement direction of the workpiece positioning fixture 44. The number and distribution of the bearing fixing blocks 33 and bearings 34 are set as needed, as shown in the figure. The number of bearing fixing blocks 33 and bearings 34 is set to four groups, distributed near the corners of the magnet collecting box 31. During operation, the magnet collecting box 31 uses the above structure to drive into or out of the equipment. Specifically, when the magnets in the magnet collecting box 31 have collected a predetermined amount, it drives out of the equipment to empty; and after emptying, it drives back into the equipment.

[0037] In one specific embodiment, the support 1 includes a gantry support 11 and a frame assembly 12 that are fixedly connected to each other; The frame assembly 12 includes a first frame 121 placed horizontally at the bottom, a second frame 122 installed vertically above the first frame 121, and a third frame 123 installed horizontally at the upper end of the second frame 122 and perpendicular to the first frame 121; the supporting base plate 35 is fixed to the top of the first frame 121; the gantry bracket 11 is installed on the top of the third frame 123; and the fixed base 4 has a fixed base plate 43 at its bottom.

[0038] The base of the telescopic cylinder is mounted on the gantry bracket 11; the fixed base plate 43 is fixedly connected to the gantry bracket 11 and / or the frame assembly 12. Specifically, the fixed base plate 43 is fixedly connected between the bottom of the gantry bracket 11 and the top of the third frame 123; The bracket 1 includes a gantry bracket 11, a fixed base plate 43, and a frame assembly 12 arranged from top to bottom. The three components form a vertical support structure to support the various components distributed in the first direction.

[0039] In summary, during the movement of the magnetic push rod 25 towards the pressure-holding fixture driven by the first driving part 51, the end of the pressure-holding head 24 preferentially contacts the end of the magnetic push rod 25. As the first driving part 51 continues to extend, the force exerted by the pressure-holding head 24 on the pressure-holding fixture is greater than the elastic force of the elastic element 26, and the elastic element 26 is compressed. At this time, the compressed elastic element 26 drives the end of the pressure-holding head 24 to exert a pressing force on the pressure-holding fixture, thereby achieving the positioning of the pressure-holding fixture and preventing the pressure-holding fixture from being misaligned by external forces. That is, the magnetic push rod is stably positioned with the magnet in the pressure-holding fixture through elastic pressure holding, ensuring zero damage during the disassembly process.

[0040] According to a second aspect of this utility model, a production line for automatically disassembling pressure-holding tooling magnets is provided, comprising: The pressure-holding tooling magnet recycling device adopts the pressure-holding tooling magnet recycling device of the first technical solution proposed above. A feeding hopper, wherein a pressure-holding fixture is provided inside which multiple magnets to be disassembled are stacked; A handling robot, the handling robot having a robotic arm for gripping the pressure holding fixture in the feeding bin, the robotic arm for placing the pressure holding fixture of the magnet to be removed into the workpiece positioning slot 441; The unloading hopper is provided with multiple storage positions for storing the pressure-holding fixtures for disassembled magnets. The robotic arm grabs the pressure-holding fixtures for disassembled magnets from the workpiece positioning slot 441 and places them in the corresponding storage positions.

[0041] Specifically, the robotic arm of the handling robot can move the pressure-holding fixture by gripping or adsorption. During loading, the robotic arm starts by gripping the pressure-holding fixture stacked at the top of the loading hopper, moves it, and places it in the workpiece positioning slot 441 of the pressure-holding fixture magnet recovery device. After the magnet is removed from the pressure-holding fixture, the robotic arm grips the pressure-holding fixture with the removed magnet and moves it to the unloading hopper. This structure effectively works in conjunction with the pressure-holding fixture magnet recovery device, achieving rapid loading and unloading, high work efficiency, and significantly improving overall work efficiency.

[0042] As one specific implementation method, it also includes: An AGV (Automated Guided Vehicle) transport vehicle is used to transport the unloading bin to a storage warehouse after the unloading bin is filled with the pressure-holding fixture for disassembling the magnets. The AGV is an automated guided vehicle that automatically transports materials, reducing manpower.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
