Description

Technical Field

[0001] This utility model relates to the field of magnet separation technology, and more specifically, to an automatic material handling machine. Background Technology

[0002] Magnets (including magnets, steel magnets, etc.) are widely used in the production of electrical and mechanical products such as motors. However, the magnets purchased or initially produced are often stacked into a strip-shaped whole (referred to as the mother magnet in this article). The individual magnets are attracted to each other by magnetic force. Before use, they need to be manually separated one by one and then placed on the discharge plate (referred to as daughter magnets in this article). Due to the strong magnetism and large magnetic force of the magnets, manual separation is difficult and not easy to operate. After separation, they need to be neatly placed on the discharge plate, resulting in low production efficiency. Furthermore, during the separation process, slight carelessness can cause the magnets to re-attract to the stacked magnets, or to adhere to other parts, or even cause damage to the magnets. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides an automatic material handling machine, including an ejector assembly, a lowering assembly, a discharge assembly, and a feeding rack for placing a mother magnet. The bottom of the feeding rack has a discharge cavity, in which a sub-magnet at the bottom of the mother magnet is located. The ejector assembly includes a ejector rod that slides back and forth. The lowering assembly includes a discharge trough and an adsorption component. The discharge trough is aligned in the front-to-back direction and communicates with the discharge cavity. The adsorption component is used to adsorb or release the sub-magnet in the discharge trough. The discharge assembly includes a discharge platform that slides back and forth. A discharge plate suitable for magnetic connection with the sub-magnet is placed on the discharge platform. The ejector rod pushes the sub-magnet from the discharge cavity to the discharge trough. The adsorption component adsorbs and fixes the position of the sub-magnet. The discharge platform slides back and forth to adjust the material handling interval of the sub-magnets. The adsorption component releases the sub-magnet, causing it to fall onto the discharge plate. The discharge plate magnetically fixes the placement position of the sub-magnet.

[0004] Optionally, the ejection assembly includes a first driving member and a pusher plate, the first driving member being connected to and driving the pusher plate to move back and forth, and a plurality of the ejector rods being distributed on the pusher plate at intervals.

[0005] Optionally, the adsorption element is a metal, a magnet, or a gas suction and release device, and the adsorption element is suitable for magnetic connection or negative pressure connection with the sub-magnet.

[0006] Optionally, the lowering assembly includes a second driving member, a third driving member, a first moving plate, and a second moving plate. The second driving member drives the first moving plate and the second moving plate to move up and down simultaneously relative to the feeding rack. The third driving member drives the first moving plate to move up and down relative to the second moving plate. The adsorption member is disposed on the first moving plate. A plurality of discharge slots are distributed on the second moving plate at left and right intervals. The adsorption member is aligned with the top of the discharge slot.

[0007] Optionally, the shape of the discharge trough is adapted to the shape of the sub-magnet, and both the first moving plate and the second moving plate are provided with mounting holes for installing the adsorption component, wherein the cross-sectional area of ​​the mounting hole is smaller than the cross-sectional area of ​​the discharge trough.

[0008] Optionally, the lowering assembly includes a slider and a connector. The second moving plate and the slider are fixedly connected by the connector. The feeding rack is provided with a first slide rail and a limiting block. The slider and the first slide rail are slidably connected up and down. The limiting block is located on the movement trajectory of the slider and restricts the upward movement of the slider.

[0009] Optionally, the discharge assembly includes a screw, a slide block, a second slide rail, a fourth drive component, a fixed base, and a sensor. The screw and the slide block are threadedly connected, and the slide block and the second slide rail are slidably connected. The fourth drive component is connected to and drives the screw to rotate. The discharge platform is connected above the slide block and moves back and forth along the screw together with the slide block. The second slide rail and the sensor are both fixed on the fixed base. The screw is rotatably mounted on the fixed base. The sensor is used to determine the moving position of the slide block to control the front-to-back spacing between the sub-magnets.

[0010] Optionally, the feeding rack is provided with a plurality of accommodating cavities spaced apart from left to right, the mother magnet is placed in the accommodating cavity, and an anti-mistake magnet is provided in the bottom of the feeding rack, the anti-mistake magnet being magnetically attracted to the mother magnet.

[0011] Optionally, the feeding rack is provided with a transparent plate on the side near the ejection assembly, which facilitates observation of the mother magnet in the receiving cavity.

[0012] Optionally, the edge of the discharge platform is provided with a stop block, which abuts against the edge of the discharge plate to restrict the installation position of the discharge plate.

[0013] Compared to existing technologies, the automatic material handling machine of this invention places the mother magnet into the feeding rack. Under its own gravity, the mother magnet falls until its bottom is in the discharge chamber. The push rod moves forward to push out the bottommost daughter magnet of the mother magnet, thus completing the separation. After the push rod moves back to its original position, the daughter magnet moves forward into the discharge trough. The discharge trough is a trough with an open bottom. The adsorption component is located above the discharge trough. The adsorption component is used to counteract the gravity of the daughter magnet and control the timing of the daughter magnet's fall. When the adsorption component releases the daughter magnet, the daughter magnet falls onto the discharge platform under the action of gravity. The discharge platform moves forward or backward to adjust the material handling spacing and prevent the next daughter magnet from piling up together after falling. The mother magnet moves downward under its own gravity, and the push rod moves forward again to push out the next sub-magnet. After the lowering component is attracted, the sub-magnet is lowered, so that the sub-magnets are placed staggered on the discharge plate. This cycle is repeated until the discharge plate is full of sub-magnets. Then, the discharge plate is removed manually or by external mechanical equipment and replaced with the next discharge plate. Then the cycle continues.

[0014] This application improves the tedious process of manually separating, aligning, and placing each magnet individually in the existing technology into an automated process, and constructs an automated magnet placement system. This system realizes automatic cyclic operation, reduces human intervention, not only improves efficiency, but also avoids problems such as placement errors, omissions, and damage caused by magnet adsorption and collision due to human fatigue and operational mistakes, thus ensuring product consistency and yield.

[0015] Mechanical positioning replaces human eyes and manual positioning. The landing point of the sub-magnets is guaranteed by the mechanical structure. By controlling the movement of the discharge table through a program, the placement interval between the sub-magnets can be easily adjusted, quickly adapting to the production requirements of different products and realizing the flexibility of the production line.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0027] This utility model embodiment provides an automatic material handling machine, combined with Figures 1 to 7 As shown, the device includes an ejection assembly, a lowering assembly, a discharge assembly, and a feeding rack 18 for placing the mother magnet. The bottom of the feeding rack 18 has a discharge cavity 19, in which the daughter magnet at the bottom of the mother magnet is located. The ejection assembly includes a push rod 1 that slides back and forth. The lowering assembly includes a discharge trough 71 and an adsorption member 61. The discharge trough 71 is aligned in the front-to-back direction and communicates with the discharge cavity 19. The adsorption member 61 is used to adsorb or release the daughter magnet in the discharge trough 71. The discharge assembly includes... The device includes a sliding discharge platform 10, on which a discharge plate 11 suitable for magnetic connection with the sub-magnet is placed. The push rod 1 pushes the sub-magnet from the discharge chamber 19 to the discharge trough 71. The adsorption member 61 adsorbs and fixes the position of the sub-magnet. The discharge platform 10 slides back and forth to adjust the placement interval of the sub-magnet. The adsorption member 61 releases the sub-magnet, allowing the sub-magnet to be placed on the discharge plate 11. The discharge plate 11 magnetically fixes the placement position of the sub-magnet.

[0028] like Figure 1 and Figure 2As shown, in this embodiment, a workbench 24 is also included, and the ejection assembly, lowering assembly, discharge assembly, and discharge rack 18 are all disposed on the workbench 24. The mother magnet is placed into the discharge rack 18, and the mother magnet falls under its own gravity until its bottom is located in the discharge cavity 19. The ejector rod 1 moves forward to eject the bottommost sub-magnet of the mother magnet, thereby completing the separation. After that, the ejector rod 1 moves backward to reset, and the sub-magnet moves forward into the discharge trough 71. The discharge trough 71 is a trough with an open bottom. The adsorption member 61 is disposed above the discharge trough 71. The adsorption member 61 is used to counteract the gravity of the sub-magnet and control the timing of the sub-magnet's fall. When the adsorption member 61 releases the sub-magnet, the sub-magnet falls onto the discharge plate 11 under the action of gravity. The discharge plate 11 moves forward or backward with the discharge platform 10 to adjust the spacing between the materials, preventing the next sub-magnet from falling and piling up together. The mother magnet moves downward under its own gravity, and the push rod 1 moves forward again to push out the next sub-magnet. After the lowering component is attracted, the sub-magnet is lowered, so that the sub-magnets are placed staggered on the discharge plate 11. This cycle is repeated until the discharge plate 11 is full of sub-magnets. Then, the discharge plate 11 is removed manually or by external mechanical equipment and replaced with the next discharge plate 11. Then the cycle continues.

[0029] The discharge plate 11 is made of metal or other materials that can magnetically attract the sub-magnets, thus firmly fixing the arranged sub-magnet array and preventing it from easily shaking or shifting. After a batch of products is completed, the operator can directly remove the entire discharge plate 11 and transfer it as a whole fixture to the next workstation for circulation or packaging, avoiding the risk of the array scattering during the transfer process.

[0030] This application improves the tedious process of manually separating, aligning, and placing each magnet individually in the existing technology into an automated process, and constructs an automated magnet placement system. This system realizes automatic cyclic operation, reduces human intervention, not only improves efficiency, but also avoids problems such as placement errors, omissions, and damage caused by magnet adsorption and collision due to human fatigue and operational mistakes, thus ensuring product consistency and yield.

[0031] Mechanical positioning replaces human eyes and manual positioning. The landing point of the sub-magnets is guaranteed by the mechanical structure. By controlling the movement of the discharge table 10 through the program, the placement interval between the sub-magnets can be easily adjusted, quickly adapting to the production requirements of different products and realizing the flexibility of the production line.

[0032] like Figure 1 As shown, optionally, the ejection assembly includes a first driving member 2 and a pusher plate 3. The first driving member 2 is connected to and drives the pusher plate 3 to move back and forth, and a plurality of push rods 1 are distributed on the pusher plate 3 at intervals.

[0033] In this embodiment, the first driving component 2 is a pneumatic or electric cylinder, and the thickness of the push rod 1 in the vertical direction is adapted to the height of the discharge chamber 19 and the thickness of the sub-magnets. The number of push rods 1 is the same as the number of mother magnets and corresponds one-to-one. This allows the equipment to simultaneously eject all sub-magnets in a row at once, rather than ejecting them one by one in sequence, thereby improving production efficiency and making it suitable for mass production.

[0034] All push rods 1 are integrated onto a single pusher plate 3 and driven by a single drive unit. This ensures the synchronicity and stability of the movement of all push rods 1, avoiding the asynchronous problems that may occur due to multiple drive units. It ensures that each row of sub-magnets is pushed out simultaneously and smoothly, with uniform force, without jamming or tilting. It also simplifies control and reduces costs.

[0035] like Figure 5 As shown, optionally, the adsorption element 61 is a metal, a magnet, or a gas suction and release device, and the adsorption element 61 is suitable for magnetic connection or negative pressure connection with the sub-magnet.

[0036] In this embodiment, the adsorption element 61 is made of metal or a magnet. It utilizes magnetic force to attract the sub-magnet, providing a direct and reliable adsorption method. During release, mechanical movement is employed to move the adsorption element 61 and the sub-magnet away from each other. When the gravitational force on the sub-magnet exceeds the magnetic attraction, it falls onto the discharge platform 10. The structure is simple and the cost is low. It should be noted that the workpieces close to the adsorption element 61 and the sub-magnet must be made of non-metallic or non-magnetic materials to avoid affecting the adsorption effect and the descent of the sub-magnet.

[0037] In other embodiments, the adsorption element 61 can be an air intake and exhaust device, which generates negative pressure adsorption through the cooperation of an air pump, air pipe, etc. The release control is very precise and rapid, and only the vacuum needs to be broken. There is no need to overcome the magnetic force, and there is no risk of magnetic interference to the sub-magnet.

[0038] like Figure 3 As shown, optionally, the lowering assembly includes a second driving member 4, a third driving member 5, a first moving plate 6, and a second moving plate 7. The second driving member 4 drives the first moving plate 6 and the second moving plate 7 to move up and down relative to the feeding rack 18 simultaneously. The third driving member 5 drives the first moving plate 6 to move up and down relative to the second moving plate 7. The adsorption member 61 is disposed on the first moving plate 6. A plurality of discharge slots 71 are distributed on the second moving plate 7 at intervals from left to right. The adsorption member 61 is aligned above the discharge slots 71.

[0039] In this embodiment, both the second driving component 4 and the third driving component 5 are pneumatic or electric cylinders. The second driving component 4 drives the adsorption component 61 and the discharge trough 71 to move downward as a whole, reducing the height of the sub-magnet and preventing it from bouncing between the sub-magnet and the discharge platform 10 when released, thus affecting the placement accuracy. The third driving component 5 drives the adsorption component 61 to move upward, thereby reducing the adsorption effect between the adsorption component 61 and the sub-magnet, allowing the sub-magnet to detach from the discharge trough 71 under its own gravity and fall onto the discharge platform 10.

[0040] If a single drive unit is used to control the second moving plate 7 to move down and detach from the adsorption unit 61, the sub-magnet will detach from the magnetic force of the adsorption unit 61 before it has moved down to the set height, which will easily cause shaking. Furthermore, if the falling height is insufficient, it will still easily bounce.

[0041] like Figure 3 and Figure 5 As shown, optionally, the shape of the discharge trough 71 is adapted to the shape of the sub-magnet, and both the first moving plate 6 and the second moving plate 7 are provided with mounting holes 62 for mounting the adsorption component 61, the cross-sectional area of ​​the mounting hole 62 being smaller than the cross-sectional area of ​​the discharge trough 71.

[0042] In this embodiment, the area difference between the discharge trough 71 and the mounting hole 62 forms a limiting wall. The limiting wall reduces the direct contact between the sub-magnet and the adsorption member 61. At the same time, when the first moving plate 6 moves the adsorption member 61 upward, the limiting wall restricts the upward movement of the sub-magnet under the action of magnetic force.

[0043] like Figure 3 As shown, optionally, the lowering component includes a slider 8 and a connector 9. The second moving plate 7 and the slider 8 are fixedly connected by the connector 9. The feeding rack 18 is provided with a first slide rail 20 and a limiting block 21. The slider 8 and the first slide rail 20 are slidably connected up and down. The limiting block 21 is provided on the movement trajectory of the slider 8 and restricts the upward movement position of the slider 8.

[0044] In this embodiment, the slider 8 and the first slide rail 20 cooperate to make the second moving plate 7 more stable when it moves downward, so that the entire lowering assembly will not shake or deviate during frequent up and down movements. The limit block 21 can prevent excessive upward movement and collision with other components, causing damage. At the same time, it can also serve as a physical reference point to ensure that the starting position of each work cycle is consistent, thereby improving the position repeatability and reliability of the equipment.

[0045] like Figure 6As shown, optionally, the discharge assembly includes a screw 13, a slide block 14, a second slide rail 15, and a fourth driving member (not shown). The screw 13 and the slide block 14 are threadedly connected, the slide block 14 and the second slide rail 15 are slidably connected, the fourth driving member is connected to and drives the screw 13 to rotate, and the discharge platform 10 is connected above the slide block 14 and moves back and forth along the screw 13 together with the slide block 14.

[0046] In this embodiment, the fourth driving component is a motor. By controlling the rotation angle of the fourth driving component, the front and rear positions of the discharge platform 10 can be controlled with extreme precision. Furthermore, a motor with a self-locking function can be selected, which can make the discharge platform 10 firmly locked in the target position when it stops, and will not deviate due to the impact of the falling magnet or its own inertia, thus ensuring the absolute accuracy of the placement interval.

[0047] like Figure 6 As shown, optionally, the discharge assembly further includes a fixed base 16 and a sensor 17. The second slide rail 15 and the sensor 17 are both fixed on the fixed base 16. The screw 13 is rotatably mounted on the fixed base 16. The sensor 17 is used to determine the moving position of the slide block 14 in order to control the front and rear placement interval between the sub-magnets.

[0048] In this embodiment, sensor 17 (such as photoelectric sensor 17, proximity switch, or grating ruler) constitutes a position closed-loop control system. It can detect the actual position of slide 14 in real time and feed the signal back to the controller (PLC or microcontroller) to achieve positioning. Variable spacing placement is achieved through program control, making it more automated and eliminating the need for manual adjustment of the mechanical structure.

[0049] like Figure 1 As shown, optionally, the feeding rack 18 is provided with a plurality of accommodating cavities 22 spaced apart from left to right, the mother magnet is placed in the accommodating cavity 22, and the bottom of the feeding rack 18 is provided with an anti-mistake magnet (not shown), the anti-mistake magnet being suitable for magnetic attraction with the mother magnet.

[0050] In this embodiment, the feeding rack 18 is fixed to the workbench 24 by bolts. The shape of the receiving cavity 22 is adapted to the shape of the mother magnet. When a mother magnet of a different shape is replaced, the entire feeding rack 18 can be replaced. It is worth noting that the receiving cavity 22 is not a through cavity; the bottom of the receiving cavity 22 has an inner wall that supports the mother magnet.

[0051] like Figure 7As shown, the bottom plate of the feeding rack 18 has fixing holes 25. An anti-misalignment magnet is installed in the fixing holes 25. The anti-misalignment magnet prevents the magnetic poles of the mother magnet from being reversed when it is inserted into the receiving cavity 22, creating a magnetic repulsion effect when reversed, preventing the mother magnet from being installed smoothly. Simultaneously, the anti-misalignment magnet also creates a magnetic attraction effect with the mother magnet when its magnetic poles are correctly installed, thus working in conjunction with the weight of the mother magnet to move it downwards, coordinating with the overall working cycle. As the child magnets in the mother magnet are gradually pushed out, making the mother magnet lighter, the anti-misalignment magnet can attract the mother magnet to continue moving downwards, preventing it from getting stuck in the receiving cavity 22, making the overall structure more stable and reliable.

[0052] Optionally, the feeding rack 18 is provided with a transparent plate 23 on the side near the ejection assembly. The transparent plate 23 facilitates observation of the mother magnet in the receiving cavity 22. The transparent plate 23 is made of acrylic material, allowing operators to quickly and intuitively check the remaining amount of the mother magnet without stopping the machine or opening the equipment, thereby determining whether material needs to be added, whether it is placed correctly, and whether the ejection process is smooth.

[0053] like Figure 1 and Figure 6 As shown, optionally, the edge of the discharge platform 10 is provided with a stop 12, which abuts against the edge of the discharge plate 11 to limit the installation position of the discharge plate 11.

[0054] In this embodiment, once a discharge plate 11 is filled with sub-magnets, the next discharge plate 11 can be easily replaced. The stop block 12 ensures that each discharge plate 11 can be quickly and accurately positioned when placed on the discharge platform 10, avoiding the trouble of recalibrating every time it is replaced.

[0055] Similarly, the components included in the "components," "mechanisms," and "devices" of this disclosure can also be flexibly combined.
