Description

Technical Field

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

[0002] In the field of injection molding ejection processes, especially for the production of plastic and MIM products, the product ejection stage is crucial, directly affecting the smoothness of the entire production process and the quality of the final product. With the continuous development of the manufacturing industry, the demand for irregularly shaped products is increasing, and the scale of injection molding production for irregularly shaped products is gradually expanding, which places higher demands on the product ejection process.

[0003] To address the issue of removing injection-molded products, the industry typically employs various methods. Among these, conventional suction cups are a commonly used tool, removing the product by adhering to its surface. However, conventional suction cups are ineffective at removing irregularly shaped products, struggling to adapt to their complex surface forms and ultimately failing to remove them successfully. Utility Model Content

[0004] To address the problem that conventional suction cups are not effective at adsorbing irregularly shaped products and are unable to adapt to the complex surface shapes of these products, thus making it difficult to remove them smoothly, this application provides an irregularly shaped product removal device.

[0005] The irregularly shaped product removal device provided in this application adopts the following technical solution:

[0006] A device for removing irregularly shaped products includes an aluminum plate fixed to a robotic arm. A first through-tube is threaded onto the aluminum plate, and a first nut is threaded onto the first through-tube. A fixing tube is threaded onto the bottom end of the first through-tube. A flexible gripper suction cup is disposed below the fixing tube. The flexible gripper suction cup includes a connecting tube disposed below the fixing tube. The bottom end of the connecting tube is connected to the flexible suction cup, and the bottom end of the flexible suction cup is connected to the flexible gripper body. A quick-change flexible gripper suction cup mounting mechanism is disposed on the fixing tube. A first air pipe is connected to the first through-tube and is connected to a negative pressure component.

[0007] By adopting the above technical solution, a robotic arm is used to move the aluminum plate, flexibly adjusting the position of the extraction device. The flexible gripper suction cup can better adapt to the complex surface shapes of irregularly shaped products, enhancing the adsorption effect, and the flexible gripper body at the bottom can assist in grasping, improving the stability of product extraction. The mounting mechanism allows for quick replacement of the flexible gripper suction cup, improving work efficiency. The first air tube connects to the negative pressure component, providing power for the adsorption operation. This improves the problems of conventional suction cups having poor adsorption effect on irregularly shaped products, difficulty in adapting to complex surface shapes, and inability to smoothly extract products.

[0008] Optionally, a second tube is threadedly connected to the aluminum plate, a second nut is threadedly connected to the second tube, a standard suction cup is threadedly connected to the end of the second tube away from the second nut, a second air pipe is connected to the second tube, and the second air pipe is connected to the negative pressure component.

[0009] By adopting the above technical solution, a standard suction cup is also installed on the aluminum plate. Combined with the connecting flexible gripper suction cup, it can effectively adsorb irregularly shaped products, improving the stability and adaptability of removing irregularly shaped products. The standard suction cup is threaded onto the aluminum plate via a second tube and a second nut for easy installation and removal. The second air tube is connected to the negative pressure component to ensure that the standard suction cup can function properly and perform its adsorption function.

[0010] Optionally, the mounting mechanism includes two sets of mounting components, which are symmetrically arranged on the flexible gripper suction cup.

[0011] By adopting the above technical solution, two sets of installation components arranged symmetrically can be used as the installation mechanism to quickly replace the flexible gripper suction cup, improve work efficiency, and ensure the stability and balance of the installation, so that the flexible gripper suction cup can better adapt to the device to complete the removal of irregularly shaped products.

[0012] Optionally, the mounting assembly includes two mounting plates fixed on the fixing pipe, a connecting rod rotating on the two mounting plates, and a clamping plate fixed on the connecting rod. A clamping block for use with the clamping plate is fixed on the connecting pipe.

[0013] By adopting the above technical solution, rotating the clamping plate and utilizing the flexibility of the clamping plate and the clamping block, the clamping plate is secured to the bottom of the clamping block, thereby achieving quick fixation of the flexible gripper suction cup. If the flexible gripper suction cup needs to be replaced, simply pry the clamping plate outward to separate it from the clamping block, thus releasing the fixation of the flexible gripper suction cup. This facilitates the replacement of different types or damaged flexible gripper suction cups, improving work efficiency.

[0014] Optionally, the top of the connecting pipe is provided with a receiving groove, and a sealing ring is embedded in the receiving groove.

[0015] By adopting the above technical solution, a receiving groove is opened at the top of the connecting tube and a sealing ring is embedded, which can further improve the sealing performance of the connection of the flexible gripper suction cup and improve the adsorption effect.

[0016] Optionally, an operating table is provided on one side of the aluminum plate, and a die-casting assembly is provided on the operating table.

[0017] By adopting the above technical solution, an operating platform and die-casting components are set on one side of the aluminum plate of the irregular product removal device. After the die-casting is completed, the robotic arm drives the removal device to move onto the die-casting lower mold to remove the irregular product.

[0018] Optionally, the die-casting assembly includes a lower die-casting mold fixed on the operating table, a connecting frame fixed on the operating table, a driving component disposed on the connecting frame, and an upper die-casting mold fixed on the driving component, wherein the upper die-casting mold is located directly above the lower die-casting mold.

[0019] By adopting the above technical solution, the die-casting upper mold is located directly above the die-casting lower mold, and the driving component drives the die-casting upper mold to perform mold closing and opening operations relative to the die-casting lower mold, thereby realizing the die-casting production of irregularly shaped products.

[0020] Optionally, the driving component is an electric push rod, and the telescopic rod of the electric push rod is fixed to the top of the die-casting upper mold.

[0021] By adopting the above technical solution, the telescopic movement can be precisely controlled by the electric push rod, which can stably drive the die-casting upper mold to perform mold closing and opening operations relative to the die-casting lower mold, making it convenient for die-casting irregularly shaped products.

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

[0023] 1. The negative pressure component draws air from the inside of the flexible suction cup and gripper through the first air pipe to create a negative pressure environment. The air pressure drives the flexible gripper body to open and close, hugging and clamping irregularly shaped products, improving the stability and reliability of gripping.

[0024] 2. The mounting components utilize the flexible cooperation of the clamping plate and the clamping block to achieve quick installation and removal of the flexible gripper suction cup, making the operation simple and fast. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a device for removing irregularly shaped products.

[0034] Example 1:

[0035] Reference Figure 1 A device for removing irregularly shaped products includes an aluminum plate 1, which serves as the mounting carrier for the entire device and is fixed to a robotic arm for movement with the arm. The aluminum plate 1 typically possesses sufficient strength and stability to withstand the weight of other components and the forces generated during operation. An operating platform 14 is also provided on one side of the robotic arm, on which a die-casting assembly 15 is mounted for producing irregularly shaped products.

[0036] Reference Figure 1 The die-casting assembly 15 includes a lower die-casting mold 1501, a connecting frame 1502, an upper die-casting mold 1503, and a driving component. The lower die-casting mold 1501 is fixed to the operating table 14, and the connecting frame 1502 is also fixed to the operating table 14. The driving component is mounted on the connecting frame 1502, and the upper die-casting mold 1503 is fixed to the driving component and located directly above the lower die-casting mold 1501. The driving component is an electric push rod 1504, and the telescopic rod of the electric push rod 1504 is fixed to the top of the upper die-casting mold 1503.

[0037] The die-casting upper mold 1503 is moved up and down by the extension and retraction of the electric push rod 1504 to realize the die casting of irregularly shaped products. The operating table 14 provides support and an operating platform for the die casting assembly 15. The extraction device is moved to the position of the die casting lower mold 1501 by operating the robotic arm, and the die-cast irregularly shaped product is easily removed by the extraction device, reducing damage to the irregularly shaped product.

[0038] Reference Figure 2A second tube 7 is threaded onto the aluminum plate 1. This connection method facilitates disassembly and installation, and makes later maintenance and component replacement convenient. A second nut 8 is threaded onto the second tube 7, which serves to tighten and prevent the second tube 7 from loosening. A standard suction cup 9 is threaded onto the bottom end of the second tube 7. The standard suction cup 9 is used to contact relatively regular surfaces of irregularly shaped products, facilitating adsorption. A second air tube 10, made of rubber hose, is threaded onto the top end of the second tube 7. The other end of the second air tube 10 is connected to a negative pressure component, which provides suction to the standard suction cup 9.

[0039] Reference Figure 3 A first connecting pipe 2 is threaded onto the aluminum plate 1. This connection method facilitates disassembly and installation, and makes later maintenance and component replacement convenient. A first nut 3 is threaded onto the first connecting pipe 2, which serves to tighten and prevent the first connecting pipe 2 from loosening. A fixing pipe 4 is threaded onto the bottom end of the first connecting pipe 2, and a flexible gripper suction cup 5 is welded and fixed to the bottom end of the fixing pipe 4. By changing the direction of turning the fixing pipe 4, the flexible gripper suction cup 5 can be disassembled and replaced. A first air pipe 6, also made of rubber hose, is threaded onto the top end of the first connecting pipe 2. In addition, the other end of the first air pipe 6 is also connected to a negative pressure component, which provides suction to the flexible gripper suction cup 5 to hold irregularly shaped products, making it easy to remove them.

[0040] Reference Figure 3 The flexible gripper suction cup 5 includes a connecting tube 51, a flexible suction cup 52, and a flexible gripper body 53. The flexible suction cup 52 is positioned between the connecting tube 51 and the flexible gripper body 53, with its top end connected to the connecting tube 51 and its bottom end connected to the flexible gripper body 53. Both the flexible suction cup 52 and the flexible gripper body 53 are made of flexible materials such as silicone, allowing for better adhesion to the complex surfaces of irregularly shaped products. The flexible gripper body 53 assists in grasping and holding irregularly shaped products.

[0041] Reference Figure 2 and Figure 3The robotic arm moves the aluminum plate 1, bringing the standard suction cup 9 into contact with the regular surface of the irregularly shaped product, while the flexible gripper suction cup 5 contacts the protruding parts of the product. Then, a negative pressure device is activated to extract air. This device draws air from the flexible suction cup 52 and the flexible gripper body 53 through the first air pipe 6, creating a negative pressure environment. This air pressure drives the flexible gripper body 53 to open and close, encircling and clamping the irregularly shaped product, improving the stability and reliability of the gripping process. The negative pressure device also draws air from the standard suction cup 9 through the second air pipe 10, creating negative pressure to grip the regular surface of the irregularly shaped product. Finally, the robotic arm moves the irregularly shaped product to the designated placement position, and the negative pressure device stops extracting air, thus placing the product in the designated location.

[0042] In Embodiment 1 of this application, the implementation principle of an irregularly shaped product removal device is as follows: The device activates a negative pressure component to evacuate air from the flexible suction cup 52 and the flexible gripper body 53 through the first air pipe 6, creating a vacuum environment. This air pressure drives the flexible gripper body 53 to unfold and close, encircling and clamping the irregularly shaped product, thus improving the stability and reliability of the gripping process and enabling the removal of the irregularly shaped product. Simultaneously, the negative pressure component also evacuates air from the standard suction cup 9 through the second air pipe 10, creating negative pressure to grip the regular surface of the irregularly shaped product. Then, a robotic arm moves the irregularly shaped product to a designated placement position, and the negative pressure component stops evacuating air, thereby placing the irregularly shaped product in the designated location.

[0043] Example 2:

[0044] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 4 The connecting pipe 51 is also threaded to the bottom end of the first through pipe 2, while the flexible gripper suction cup 5 is located below the connecting pipe 51 and is no longer fixed to the connecting pipe 51 by welding.

[0045] Reference Figure 4 An installation mechanism is provided on the fixed pipe 4, and the installation mechanism includes two sets of installation components 11, which are symmetrically arranged on the fixed pipe 4. Each installation component 11 includes two mounting plates 1101, a connecting rod 1102, a clamping plate 1103, and a clamping block 1104. The two mounting plates 1101 are fixed to the fixed pipe 4, the connecting rod 1102 rotates on an adjacent side of the two mounting plates 1101, and the clamping plate 1103 is fixed to the connecting rod 1102, allowing the clamping plate 1103 to also rotate. The clamping block 1104 is fixed to the connecting pipe 51, and both the clamping plate 1103 and the clamping block 1104 are made of plastic and are durable.

[0046] By rotating the clamping plate 1103 downwards, the clamping plate 1103 locks the clamping block 1104, thereby enabling the rapid installation of the flexible gripper suction cup 5. By rotating the clamping plate upwards, the clamping plate 1103 disengages from the clamping block 1104, releasing the fixation on the flexible gripper suction cup 5. The operation is simple, quick, and time-saving.

[0047] Reference Figure 5 A receiving groove 12 is provided at the top of the connecting tube 51, and a sealing ring 13 is embedded in the receiving groove 12 to further improve the sealing performance at the connection between the flexible gripper suction cup 5 and the fixed tube 4, improve the air extraction effect, and thus ensure that the flexible gripper suction cup 5 can stably grip irregular products.
