Description

Technical Field

[0001] This application relates to the field of absorbing irregularly shaped products, and in particular to a magnetic absorbing device for irregularly shaped products. Background Technology

[0002] With the continuous development of the manufacturing industry, MIM (Metal Injection Molding) products have been widely used in various fields, and automated production is gradually becoming an industry trend. Automated production can not only improve the production efficiency of MIM products and reduce labor costs, but also enhance the stability and consistency of MIM product quality.

[0003] In the field of automated manufacturing of MIM (Mechanical Manufacturing) products, the conventional method for picking up and moving irregularly shaped products involves using standard industrial suction cups and controlling air pressure with solenoid valves. This method, to some extent, can be combined with robotic arms to achieve the picking up and moving of irregularly shaped products. However, when picking up complex or small, magnetic irregularly shaped products, the suction cups struggle to fully adhere to the surface, resulting in insufficient suction and frequent missed pick-ups. This prevents the irregularly shaped products from being smoothly moved mechanically and accurately placed into the mold for production, severely impacting production efficiency. Utility Model Content

[0004] In order to improve the problem that when suction cups pick up complex or small magnetic irregularly shaped products, it is difficult for the suction cups to fully adhere to the surface of such irregularly shaped products, resulting in insufficient suction force and affecting the movement of such irregularly shaped products, this application provides a magnetic suction device for irregularly shaped products.

[0005] The magnetic attraction device for irregularly shaped products provided in this application adopts the following technical solution:

[0006] A magnetic attraction device for irregularly shaped products includes a mounting block fixed on a robotic arm. A protective shell is fixed to one side of the mounting block, and a driving component is fixed inside the protective shell. A guide plate is provided below the driving component, and a limiting groove is opened on the guide plate. A magnetic component for adsorbing irregularly shaped products is provided between the driving component and the guide plate, and the magnetic component slides within the limiting groove.

[0007] By adopting the above technical solution, the power source drives the magnetic component to move up and down within the limiting groove on the guide plate. Utilizing the magnetic force between the magnetic component and the irregularly shaped product, the product is attracted and detached. This avoids the problems of missed suction and shaking that occur with traditional suction cups when picking up complex or small irregularly shaped products, ensuring that irregularly shaped products can be smoothly moved mechanically and accurately placed into the mold for production, thus improving production efficiency.

[0008] Optionally, the protective shell has a through hole, the driving component is a cylinder, and the air pipe on the cylinder passes through the through hole to connect to an external air source.

[0009] By adopting the above technical solution, using a cylinder as the driving component, and connecting the cylinder to an external air source through a through hole on the protective shell, it is convenient to use air pressure to drive the cylinder to control the movement of the magnetic component and provide power for the magnetic attraction device.

[0010] Optionally, the guide plate is also fixed to the robotic arm, and the inner wall of the limiting groove is provided with a lubricating coating.

[0011] By adopting the above technical solution, both the mounting block and the guide plate are fixed on the robotic arm, enabling the magnetic suction device to move along with the robotic arm, thereby placing irregularly shaped products in a designated position. The lubricating coating reduces the friction when the magnetic components slide within the limiting groove.

[0012] Optionally, the magnetic assembly includes a first magnetic block threadedly connected to the cylinder piston rod, and a second magnetic block fixed to the bottom of the first magnetic block, the second magnetic block sliding within a limiting groove.

[0013] By adopting the above technical solution, the first magnetic block is threaded onto the cylinder piston rod, facilitating the disassembly and replacement of the magnetic assembly. The second magnetic block slides within the limiting groove, providing a guiding function and making the movement of the magnetic assembly more stable.

[0014] Optionally, the guide plate is a non-magnetic plate, and the protective shell is also provided with heat dissipation holes.

[0015] By adopting the above technical solution, the use of a non-magnetic guide plate can avoid interference with the magnetic field of the magnetic components. The heat dissipation holes can help cool the cylinder, extending its service life.

[0016] Optionally, the cross-sectional dimensions of the second magnetic block are the same as the cross-sectional dimensions of the limiting groove.

[0017] By adopting the above technical solution, the second magnetic block can slide stably in the limiting groove, avoiding shaking, improving the stability and reliability of the magnetic component's movement, and thus ensuring the accuracy and stability of the device's picking up and moving of irregularly shaped products.

[0018] Optionally, a sponge layer is fixed to the bottom of the guide plate, and a groove is opened on the sponge layer to cooperate with the limiting groove.

[0019] By adopting the above technical solution, a sponge layer is fixed at the bottom of the guide plate and a groove is opened to cooperate with the limiting groove, which can play a buffering role and prevent the device from damaging the product when picking up the irregular product, thus affecting the quality of the irregular product.

[0020] Optionally, the bottom of the guide plate and the bottom of the sponge layer are both arranged in an arc shape.

[0021] By adopting the above technical solution, the bottom of the guide plate and the bottom of the sponge layer are both set in an arc shape, which enables the magnetic attraction device to better adapt to the shape of irregular products, enhance the contact fit with irregular products, and further ensure the stability and reliability of magnetic attraction.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] A cylinder drives the magnetic component to slide up and down within a limiting groove. Utilizing the magnetic force between the component and the irregularly shaped product, the product is attracted and detached. The magnetic attraction device moves along with the robotic arm, accurately placing the irregularly shaped product into the mold for production, thus improving the production efficiency of MIM (Metal Injection Molding) type irregularly shaped products.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a magnetic attraction device for irregularly shaped products.

[0032] In this embodiment, the irregularly shaped product is a complex or compact irregularly shaped product that is magnetic.

[0033] Reference Figure 1 and Figure 4 A magnetic attraction device for irregularly shaped products includes a mounting block 1 and a guide plate 3 fixed to a robotic arm. The guide plate 3 has a limiting groove 4 and is positioned directly below the mounting block 1. The mounting block 1 and guide plate 3 are used to fix the magnetic attraction device to the robotic arm, allowing the device to move synchronously with the robotic arm. A protective shell 2 is fixed to one side of the mounting block 1, and a driving component is installed inside the protective shell 2. The protective shell 2 protects the driving component from interference and damage from the external environment.

[0034] Reference Figure 2 A through hole 7 is provided on the protective shell 2. In this embodiment, a cylinder 6 is selected as the driving component. The cylinder 6 has the advantages of large output force and fast response speed. An external air source is connected to the cylinder 6 located inside the protective shell 2 through the through hole 7. The external air source provides compressed air to the cylinder 6, enabling the piston rod of the cylinder 6 to perform telescopic movement. In addition, a heat dissipation hole 9 is also provided on the protective shell 2 to help dissipate heat from the cylinder 6 and prevent the cylinder 6 from being damaged due to overheating.

[0035] Reference Figure 2 and Figure 3 A magnetic component 5 for adsorbing irregularly shaped products is provided between the mounting block 1 and the guide plate 3, and the magnetic component 5 slides on the limiting groove 4. In the magnetic adsorption device, the cylinder 6 provides power for the movement of the magnetic component 5. The limiting groove 4 provides guidance for the movement of the magnetic component 5, ensuring that the magnetic component 5 can accurately adsorb and release irregularly shaped products.

[0036] In addition, the guide plate 3 is a non-magnetic plate. In this embodiment, the guide plate 3 is made of aluminum plate to avoid interfering with the magnetic field of the magnetic component 5. A lubricating coating 8 is provided on the inner wall of the limiting groove 4, which can reduce the friction generated when the magnetic component 5 moves in the limiting groove 4, making the magnetic component 5 slide more smoothly in the limiting groove 4.

[0037] Reference Figure 3 and Figure 4 The magnetic component 5 includes a first magnetic block 51 and a second magnetic block 52. The first magnetic block 51 is threadedly connected to the piston rod of the cylinder 6, and the second magnetic block 52 is fixed below the first magnetic block 51 and slides within the limiting groove 4. Both the first magnetic block 51 and the second magnetic block 52 are made of permanent magnet material and possess strong magnetism.

[0038] In addition, the first magnetic block 51 is connected to the piston rod of the cylinder 6 by a threaded connection, which facilitates the disassembly and replacement of the magnetic assembly 5. The cross-sectional dimensions of the second magnetic block 52 are the same as those of the limiting groove 4, so that the limiting groove 4 can limit the movement trajectory of the second magnetic block 52, ensuring the stability of the movement of the second magnetic block 52 and preventing deviation from the preset movement trajectory, thus avoiding adsorption deviation.

[0039] Reference Figure 1 and Figure 4 With the cooperation of the first magnetic block 51 and the second magnetic block 52, a strong magnetic field is formed. When the control cylinder 6 extends its piston rod, it drives the magnetic component 5 to move downward, close to the irregularly shaped product, and generate a magnetic force, which attracts the irregularly shaped product.

[0040] After the adsorbed irregularly shaped product is moved by the robotic arm to the designated station of the mold, the control cylinder 6 retracts its piston rod, which drives the magnetic component 5 to move upward and away from the irregularly shaped product. The magnetic force disappears, causing the irregularly shaped product to detach from the adsorption state and be released.

[0041] The guide plate 3 is made of aluminum and is non-magnetic. When releasing irregularly shaped products, the guide plate 3 can restrict the irregularly shaped products from moving upward with the magnetic component 5, ensuring that the irregularly shaped products are completely and accurately removed from the shaping fixture.

[0042] Reference Figure 4 A sponge layer 10 is fixed at the bottom of the guide plate 3. A groove is opened on the sponge layer 10 to cooperate with the limiting groove 4, so as to ensure that the magnetic component 5 can pass smoothly through the sponge layer 10. The sponge layer 10 has a buffering effect, which can prevent the magnetic component 5 from directly colliding with irregularly shaped products and damaging the products.

[0043] Reference Figure 4 Both the bottom of the guide plate 3 and the bottom of the sponge layer 10 are set in an arc shape. This shape design can better adapt to the surface shape of irregular products and improve the adsorption effect.

[0044] The implementation principle of the magnetic attraction device for irregularly shaped products in this application embodiment is as follows: the cylinder 6 drives the magnetic component 5 to slide up and down in the limiting groove 4. The magnetic force between the magnetic component 5 and the irregularly shaped product is used to achieve the attraction and detachment of the product. The magnetic attraction device moves along with the robotic arm, accurately placing the irregularly shaped product into the mold for production, thus improving the production efficiency of MIM-type irregularly shaped products.
