Description

Technical Field

[0001] This application relates to the field of irregularly shaped product retrieval, and in particular to a MIM-type irregularly shaped product retrieval device. 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, non-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] To address the problem that suction cups struggle to fully adhere to the surface of complex or small, non-magnetic irregularly shaped products when picking them up, resulting in insufficient suction and hindering the movement of such products, this application provides a suction device for MIM-type irregularly shaped products.

[0005] The technical solution of the MIM-type irregularly shaped product suction device provided in this application is as follows: A suction device for irregularly shaped MIM products includes a mounting plate fixed to a robotic arm and a fixing block fixed to the mounting plate. The bottom of the fixing block has a receiving groove, and the receiving groove is filled with conformal polyurethane. The fixing block is provided with a connecting mechanism for quick assembly and disassembly of the conformal polyurethane. The fixing block has an air extraction hole. A negative pressure component is provided on one side of the mounting block. The air extraction hole is connected to the negative pressure component. The fixing block also has an air suction hole, and the air extraction hole is connected to the air suction hole. The conformal polyurethane is disposed below the air suction hole.

[0006] By adopting the above technical solution, the mounting plate allows the suction device to be installed on the robotic arm for easy operation. The receiving groove and connecting mechanism secure the conformal polyurethane to the fixed block. The robotic arm moves the suction device to a designated position, ensuring the conformal polyurethane adheres to the surface of the irregularly shaped product. Then, the negative pressure component is activated, generating negative pressure at the conformal polyurethane through the suction and extraction ports, creating suction to pull up the irregularly shaped product. This suction device improves upon the problem of insufficient suction due to poor suction cup adhesion, which hinders the movement of irregularly shaped products.

[0007] Optionally, the negative pressure component is a vacuum pump, and the vacuum pump's suction pipe is threadedly connected to the suction port.

[0008] By adopting the above technical solution, the vacuum pump can provide stable and reliable negative pressure suction, facilitating the effective suction of irregularly shaped products. Connecting the vacuum pump's suction pipe threaded onto the suction port facilitates the installation and disassembly of the negative pressure components, aiding in equipment maintenance and parts replacement.

[0009] Optionally, multiple air intake holes are provided, and the multiple air intake holes are evenly spaced.

[0010] By adopting the above technical solution, multiple evenly spaced suction holes can make the suction force generated at the conformal polyurethane more uniform, which helps to improve the suction effect on complex or small non-magnetic irregular products.

[0011] Optionally, the shape of the conformal polyurethane is matched with the shape of the irregularly shaped product.

[0012] By adopting the above technical solution, the bottom of the contoured polyurethane matches the shape of the irregular product, which allows the contoured polyurethane to better adhere to the surface of the irregular product and facilitates subsequent adsorption.

[0013] Optionally, the mounting block is provided with a vent hole, which is connected to an air extraction hole.

[0014] By adopting the above technical solution, the vent hole and the extraction hole are connected, enabling the robotic arm to move the suction device. After the adsorbed irregularly shaped product is moved to the designated position, the vacuum pump stops pumping air. Outside air enters the interior of the fixed block through the vent hole, the negative pressure at the conformal polyurethane disappears, and the irregularly shaped product naturally falls off and enters the designated station of the mold.

[0015] Optionally, the connecting mechanism includes a connecting plate fixed on a fixing block, the connecting plate having a threaded hole, and an abutment bolt threaded into the threaded hole.

[0016] By adopting the above technical solution, the distance between the abutting bolt and the conformal polyurethane can be changed by tightening the abutting bolt, which facilitates quick and easy disassembly and assembly of the conformal polyurethane. The appropriate conformal polyurethane can be replaced according to different irregularly shaped products.

[0017] Optionally, the connecting mechanism further includes a receiving plate fixed on the conformal polyurethane, the receiving plate having a receiving groove that mates with the abutment bolt.

[0018] By adopting the above technical solution, a stable connection between the conformal polyurethane and the fixing block is achieved through the threaded engagement between the abutting bolt and the inner wall of the receiving groove, while facilitating the subsequent quick disassembly and replacement of the conformal polyurethane.

[0019] Optionally, the connecting mechanism is provided in two sets, with the two sets of connecting mechanisms respectively located on both sides of the conformal polyurethane.

[0020] By adopting the above technical solution and setting two sets of connecting mechanisms located on both sides of the conformal polyurethane, the installation and disassembly of the conformal polyurethane can be made more stable and convenient, and it is easy to replace the conformal polyurethane with a suitable one according to different irregular products.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Start the vacuum pump to evacuate the fixed block. With the air extraction port and the air intake port connected, a negative pressure is generated at the shape-conforming polyurethane, which generates suction and thus picks up the irregularly shaped product. 2. By setting the shape of the polyurethane to match the shape of the irregular product, it can better fit the surface of complex or small non-magnetic irregular products, ensuring the stability of absorption.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a device for absorbing irregularly shaped MIM products.

[0027] Example 1: Reference Figure 1 and Figure 2 A picking device for irregularly shaped MIM products includes a mounting plate 1 fixed to a robotic arm. By connecting the mounting plate 1 to the robotic arm, the entire picking device can move synchronously with the robotic arm to realize the handling of irregularly shaped products.

[0028] A mounting block 2 is fixed on the mounting plate 1, providing a mounting base for other components. A negative pressure component, in this embodiment, is a vacuum pump, located on the outside of the mounting block 2. An air extraction hole 6 is provided on the mounting block 2, and this hole 6 is threadedly connected to the air extraction pipe of the vacuum pump. This threaded connection facilitates the installation and removal of the air extraction pipe from the vacuum pump from the air extraction hole 6 on the mounting block 2, while also ensuring a tight seal at the connection point.

[0029] Reference Figure 3 The fixed block 2 also has suction holes 7, which are connected to the extraction holes 6. The diameter of the suction holes 7 is generally small to ensure sufficient suction force, and multiple suction holes 7 are provided, which are evenly spaced apart. This makes the suction force distribution more uniform and improves the effect of sucking up irregularly shaped products.

[0030] A receiving groove 3 is provided at the bottom of the fixing block 2, and a conforming polyurethane 4 is placed in the receiving groove 3, which is positioned below the suction hole 7. The conforming polyurethane 4 is made of polyurethane material, which has soft and wear-resistant properties. It can conform to the shape of irregular products, so that the conforming polyurethane 4 can fit and suck up the irregular products, thereby ensuring a stable product suction process.

[0031] When suctioning irregularly shaped products, the robotic arm first moves the conformal polyurethane 4 on the suction device to a position where it adheres to the surface of the irregularly shaped product. Then, the vacuum pump is activated to evacuate the fixed block 2, creating a negative pressure at the conformal polyurethane 4, which generates suction and allows the irregularly shaped product to be suctioned.

[0032] Reference Figure 2 and Figure 3 Ventilation holes 8 are also provided on the fixed block 2, and the ventilation holes 8 are connected to the air extraction holes 6. Although outside air will enter the fixed block 2 through the ventilation holes 8, when the vacuum pump is started to evacuate the fixed block 2, the air flow rate that is extracted from the fixed block 2 is much greater than the flow rate of outside air entering the fixed block 2 through the ventilation holes 8. Therefore, when the vacuum pump is started to evacuate the fixed block 2, the shape-conforming polyurethane 4 can still be kept under negative pressure, generating suction to suck up irregularly shaped products.

[0033] In addition, the vent 8 can balance the air pressure inside the fixing block 2, preventing excessively high or low air pressure during the suction process and ensuring its stability. High air pressure inside the fixing block 2 will result in excessive suction on irregularly shaped products, causing pressure on their surface and damaging their quality. Low air pressure inside the fixing block 2 will result in insufficient suction, failing to adsorb irregularly shaped products and causing them to detach during the suction process.

[0034] When it is necessary to release irregularly shaped products, simply control the vacuum pump to stop pumping air, and outside air enters the interior of the fixing block 2 through the vent 8, causing the negative pressure at the joint between the polyurethane 4 and the irregularly shaped product to disappear, thereby losing the adsorption effect on the irregularly shaped product and completing the release of the irregularly shaped product.

[0035] In the first embodiment of this application, the implementation principle of a MIM-type irregular product suction device is as follows: a vacuum pump is connected to a suction port 6 through a suction pipe. When the vacuum pump is working, the gas is extracted through the suction port 7 and the suction port 6, forming a negative pressure at the joint between the conformal polyurethane 4 and the irregular product, generating suction, thereby realizing the suction of the irregular product.

[0036] Example 2: The difference between Example 2 and Example 1 is that: (Refer to...) Figure 2 and Figure 4 Connecting mechanisms 5 are provided on both sides of the conformal polyurethane 4, enabling quick assembly and disassembly of the conformal polyurethane 4 and thus facilitating its replacement. By processing the conformal polyurethane 4 into a shape that fits different irregularly shaped products, it is possible to extract different types of irregularly shaped products.

[0037] Reference Figure 3 The connecting mechanism 5 consists of a connecting plate 51 fixed to the fixing block 2 and a receiving plate 54 fixed to the conformal polyurethane 4. A threaded hole 52 is formed in the connecting plate 51, and a connecting bolt 53 is threaded into the threaded hole 52. A receiving groove 55 is formed in the receiving plate 54, and a threaded structure that mates with the connecting bolt 53 is provided on the inner wall of the receiving groove 55.

[0038] When the abutment bolt 53 is rotated clockwise, the threaded structure inside the receiving groove 55, combined with the abutment bolt 53, fixes the conformal polyurethane 4 into the receiving groove 3 on the fixing block 2. When the abutment bolt 53 is rotated counterclockwise, the abutment bolt 53 is unscrewed from the receiving groove 55, thereby releasing the fixing effect between the connecting plate 51 and the receiving plate 54, allowing the conformal polyurethane 4 to be removed for replacement or repair.
