Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a suction cup device. Background Technology

[0002] In the production and processing of sheet materials such as paper cards, each piece of product material needs to be accurately transferred to the corresponding processing station so that the equipment at the processing station can perform precise processing, thereby ensuring the quality of the produced products.

[0003] In existing technologies, suction cup mechanisms are typically used to pick up products from the conveyor belt and then transfer them to the corresponding processing station. However, in actual operation, it is difficult to guarantee the accuracy of the equipment's feeding, which leads to deviations in the position of the conveyor belt. As a result, the suction cup mechanism cannot accurately align with the product in the conveyor belt, affecting the normal material picking by the suction cup mechanism and thus reducing production efficiency. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a suction cup device that avoids the problem that the suction cup mechanism cannot properly pick up materials due to the deviation of the material belt, thereby affecting production efficiency.

[0005] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0006] This utility model provides a suction cup device, comprising:

[0007] A suction cup mechanism includes a suction plate having suction holes;

[0008] A positioning mechanism includes a positioning component and a positioning drive. The positioning component is located on the side of the suction plate opposite to the suction hole and is movably inserted through the suction plate. The positioning drive is driven to the positioning component to drive the positioning component to extend out of or retract from the suction plate.

[0009] The material support mechanism is used to support the material belt. The material support mechanism has a positioning hole that cooperates with the positioning component. When the positioning component extends out of the suction plate, it abuts against the positioning hole.

[0010] In some implementations, the positioning component includes a positioning plate and a positioning pin. The positioning plate is located on the side of the suction plate opposite to the suction hole. The first end of the positioning pin is connected to the positioning plate, and the second end of the positioning pin is movably inserted through the suction plate. The positioning drive is driven and connected to the positioning plate.

[0011] In this implementation, the positioning drive unit drives the positioning plate to descend, which in turn drives the positioning pin to descend, thereby causing the positioning pin to extend out of the suction plate; the positioning drive unit drives the positioning plate to rise, which in turn drives the positioning pin to rise, thereby causing the positioning pin to retract into the suction plate, ensuring the reliability of the positioning component and making the overall structure more compact.

[0012] In some implementations, the suction cup mechanism further includes a bearing, and the suction plate is provided with a connecting hole. The bearing passes through the connecting hole, and the second end of the positioning pin is movably inserted through the bearing.

[0013] In some implementations, the second end of the positioning pin has an inclined guide surface.

[0014] In this implementation, the positioning pin passes through the alignment hole and abuts against the positioning hole. After passing through the alignment hole, the positioning pin enters the positioning hole through the guide surface, thereby correcting the material strip and ensuring the positioning accuracy between the suction plate and the product.

[0015] In some implementations, there are multiple positioning pins, with the first ends of the multiple positioning pins respectively connected to the positioning plate, and the second ends of the multiple positioning pins respectively movably passing through the periphery of the suction plate.

[0016] In this implementation, the material feeding mechanism has multiple positioning holes, and the material strip has multiple alignment holes. The product is located in the middle of the material strip, and the multiple alignment holes are located on the periphery of the product. When the suction plate picks up the product, the multiple positioning pins pass through the multiple alignment holes one by one and abut against the multiple positioning holes, thereby ensuring the alignment accuracy between the product and the suction plate.

[0017] In some implementations, the positioning drive includes a drive cylinder having a piston rod, the drive cylinder being connected to the side of the suction plate opposite to the suction hole, and the piston rod being connected to the positioning plate.

[0018] In some implementations, the suction cup mechanism further includes a connecting plate, a connecting column, and a suction drive component. The two opposite ends of the connecting column are respectively connected to the connecting plate and the side of the suction plate away from the suction hole. The positioning plate is located between the connecting plate and the suction plate. The suction drive component is driven and connected to the connecting plate.

[0019] In this implementation, the connecting plate and the suction plate are connected by a connecting column, and the positioning plate is located between the connecting plate and the suction plate. The suction drive component drives the connecting plate to move, thereby driving the suction plate and the positioning mechanism to move to a preset position.

[0020] In some implementations, the suction cup mechanism further includes a negative pressure connector, one end of which is connected to the suction plate, and the other end of which is connected to an external negative pressure source.

[0021] In some implementations, the suction cup mechanism further includes an elastic buffer member connected to the side of the suction plate having the suction hole, and the elastic buffer member having a through hole communicating with the suction hole.

[0022] In this implementation, the elastic buffer can provide a good cushioning effect when the suction plate comes into contact with the product, so that the product can be more stably sucked up by the suction plate.

[0023] In some implementations, the material support mechanism includes a material support plate, which is arranged parallel to the suction plate, and the positioning hole is formed on the material support plate.

[0024] In summary, this utility model has at least the following advantages:

[0025] The suction cup device provided by this utility model has a positioning component located on the side of the suction plate opposite to the suction hole and movably inserted through the suction plate. The positioning drive drives the positioning component to extend or retract relative to the suction plate. The material support mechanism has a positioning hole that cooperates with the positioning component. The material strip placed on the material support mechanism has an alignment hole that corresponds to the positioning hole. When the positioning component extends out of the suction plate, it passes through the alignment hole and abuts against the positioning hole, thereby correcting the deviation of the material strip so that the product in the material strip is centered and aligned with the suction plate. This ensures that the suction plate can accurately pick up the product in the material strip and avoids the problem that the suction cup mechanism cannot pick up the material normally due to the deviation of the material strip, thus affecting the production efficiency.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Please see the appendix Figure 1 ~Appendix Figure 5 The suction cup device of this utility model includes a suction cup mechanism 10, a positioning mechanism 20, and a material support mechanism 30.

[0043] In this regard, please combine Figures 1 to 4 , Figure 1 The diagram illustrates the structural relationship between the suction cup mechanism 10, the positioning mechanism 20, and the material support mechanism 30 in this embodiment of the invention. Figure 2 and Figure 4The illustration shows the specific structures of the suction cup mechanism 10, the positioning mechanism 20, and the material support mechanism 30 in this embodiment of the present invention. Specifically, the suction cup mechanism 10 includes a suction plate 11 with a suction hole 111; the positioning mechanism 20 includes a positioning component 21 and a positioning drive component 22. The positioning component 21 is located on the side of the suction plate 11 opposite to the suction hole 111 and is movably inserted through the suction plate 11. The positioning drive component 22 is driven to connect to the positioning component 21 to drive the positioning component 21 to extend out of or retract from the suction plate 11; the material support mechanism 30 is used to support the material belt 40. The material support mechanism 30 has a positioning hole 31 that cooperates with the positioning component 21. When the positioning component 21 extends out of the suction plate 11, it abuts against the positioning hole 31.

[0044] In this embodiment, the positioning component 21 is located on the side of the suction plate 11 opposite to the suction hole 111 and can be movably inserted through the suction plate 11. That is, the positioning component 21 can be inserted from the side of the suction plate 11 opposite to the side of the suction plate 11 with the suction hole 111. The material support mechanism 30 is provided with a positioning hole 31 that cooperates with the positioning component 21. The positioning drive 22 drives the positioning component 21 to extend or retract relative to the suction plate 11. When the positioning drive 22 drives the positioning component 21 to extend out of the suction plate 11, the positioning component 21 abuts against the positioning hole 31 of the material support mechanism 30.

[0045] Specifically, please combine Figure 2 and Figure 3 The material support mechanism 30 has a material belt 40, which has a product 41 for the suction cup mechanism 10 to pick up, and an alignment hole 42 corresponding to the positioning hole 31. During the production process, the material belt 40 is conveyed to the material support mechanism 30 through the transmission mechanism. The alignment hole 42 on the material belt 40 corresponds to the positioning hole 31 on the material support mechanism 30. The pallet mechanism descends, driving the positioning mechanism 20 to descend to the preset position. At the same time, the positioning drive 22 drives the positioning component 21 to extend from the suction plate 11, pass through the alignment hole 42 and enter the positioning hole 31, so that the product 41 is centered and aligned with the suction plate 11, that is, the product 41 is within the suction range of the suction hole 111 on the suction plate 11, thereby accurately positioning the product 41. Then the suction plate 11 abuts against the product 41, the suction cup mechanism 10 stops descending, the suction plate 11 sucks up the product 41 and rises, thereby peeling the product 41 from the material belt 40 and moving it away from the material belt 40. The positioning drive 22 drives the positioning component 21 to retract into the suction plate 11, thereby realizing the correction of the material belt 40 and ensuring that the suction cup mechanism 10 can pick up materials normally.

[0046] It is understandable that if the material belt 40 deviates during the conveying process, the material belt 40 will undergo slight displacement as the positioning component 21 passes through the alignment hole 42 and abuts against the positioning hole 31. This allows the positioning component 21 to pass smoothly through the alignment hole 42 and abut against the positioning hole 31, thereby correcting the deviation of the material belt 40 and ensuring that the product 41 is normally picked up by the suction plate 11.

[0047] In the aforementioned suction cup device, the positioning component 21 is located on the side of the suction plate 11 opposite to the suction hole 111 and can be movably inserted through the suction plate 11. The positioning drive component 22 drives the positioning component 21 to extend or retract relative to the suction plate 11. The material support mechanism 30 has a positioning hole 31 that cooperates with the positioning component 21. The material strip 40 placed on the material support mechanism 30 has an alignment hole 42 that corresponds to the positioning hole 31. When the positioning component 21 extends out of the suction plate 11, the positioning component 21 passes through the alignment hole 42 and abuts against the positioning hole 31, thereby correcting the deviation of the material strip 40 so that the product 41 in the material strip 40 is centered and aligned with the suction plate 11. This ensures that the suction plate 11 can accurately pick up the product 41 in the material strip 40, avoiding the problem that the suction cup mechanism 10 cannot pick up the material normally due to the deviation of the material strip 40, thus affecting the production efficiency.

[0048] In some preferred embodiments, please refer to Figure 4 , Figure 4 The diagram illustrates the structural relationship between the positioning plate 211 and the positioning pin 212 in this embodiment of the present invention. Specifically, the positioning assembly 21 includes a positioning plate 211 and a positioning pin 212. The positioning plate 211 is located on the side of the suction plate 11 opposite to the suction hole 111. The first end of the positioning pin 212 is connected to the positioning plate 211, and the second end of the positioning pin 212 is movably inserted through the suction plate 11. The positioning drive member 22 is driven and connected to the positioning plate 211. The positioning drive member 22 drives the positioning plate 211 to descend, causing the positioning pin 212 to descend, thereby causing the positioning pin 212 to extend out of the suction plate 11. The positioning drive member 22 also drives the positioning plate 211 to rise, causing the positioning pin 212 to rise, thereby causing the positioning pin 212 to retract into the suction plate 11. This ensures the reliability of the positioning assembly 21 and makes the overall structure more compact.

[0049] In some preferred embodiments, the suction cup mechanism 10 further includes a bearing 12, and the suction plate 11 also has a connecting hole 112. The bearing 12 passes through the connecting hole 112, and the second end of the positioning pin 212 movably passes through the bearing 12. The bearing 12 reduces the friction between the suction plate 11 and the positioning pin 212, thereby extending the service life of the positioning mechanism 20. Preferably, the bearing 12 can be an oil-free bushing, which forms a lubricating film on the friction surface through a solid lubricating material, reducing the coefficient of friction without external oil supply, while also reducing power loss and maintenance workload.

[0050] In some preferred embodiments, please refer to Figure 5 , Figure 5 The diagram illustrates the specific structure of the guide surface 2121 in this embodiment of the invention. Specifically, the second end of the positioning pin 212 has an inclined guide surface 2121. This facilitates the positioning pin 212 passing through the alignment hole 42 and abutting against the positioning hole 31. After passing through the alignment hole 42, the positioning pin 2122 enters the positioning hole 31 via the guide surface 2121, thereby correcting the deviation of the material strip 40 and ensuring the positioning accuracy between the suction plate 11 and the product 41.

[0051] In some preferred embodiments, there are multiple positioning pins 212, with the first ends of the multiple positioning pins 212 respectively connected to the positioning plate 211, and the second ends of the multiple positioning pins 212 respectively movably passing through the periphery of the suction plate 11.

[0052] Specifically, the material support mechanism 30 has multiple positioning holes 31, and the material belt 40 has multiple alignment holes 42. The product 41 is located in the middle of the material belt 40, and the multiple alignment holes 42 are located on the periphery of the product 41. When the suction plate 11 picks up the product 41, the multiple positioning pins 212 pass through the multiple alignment holes 42 one by one and abut against the multiple positioning holes 31, thereby ensuring the alignment accuracy between the product 41 and the suction plate 11.

[0053] In some more preferred embodiments, please refer to Figure 4 , Figure 4 The diagram illustrates the specific structure of the positioning drive component 22 in this embodiment of the present invention. Specifically, the positioning drive component 22 includes a drive cylinder 221, which has a piston rod 222. The drive cylinder 221 is connected to the side of the suction plate 11 opposite to the suction hole 111, and the piston rod 222 is connected to the positioning plate 211. The drive cylinder 221 drives the piston rod 222 to extend and retract, and the extension and retraction of the piston rod 222 causes the positioning plate 211 to move relative to the suction plate 11, thereby causing the positioning pin 212 to extend out of or retract from the suction plate 11.

[0054] Example 2:

[0055] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the suction cup device of this utility model. Please refer to the appendix. Figure 6 ~Appendix Figure 7 .

[0056] Please see below. Figure 6 , Figure 6The diagram illustrates the structural relationship between the connecting plate 13, the connecting post 14, and the suction plate 11 in this embodiment of the present invention. Specifically, the suction cup mechanism 10 further includes the connecting plate 13, the connecting post 14, and the suction drive member 15. The two opposite ends of the connecting post 14 are respectively connected to the connecting plate 13 and the side of the suction plate 11 facing away from the suction hole 111. The positioning plate 211 is located between the connecting plate 13 and the suction plate 11. The suction drive member 15 is driven and connected to the connecting plate 13.

[0057] In this embodiment, the connecting plate 13 and the suction plate 11 are connected by a connecting post 14. The positioning plate 211 is located between the connecting plate 13 and the suction plate 11. The suction drive 15 drives the connecting plate 13 to move, thereby driving the suction plate 11 and the positioning mechanism 20 to move to a preset position. After the suction plate 11 picks up the product 41 in the material belt 40, the suction drive 15 drives the connecting plate 13 to move, thereby driving the suction plate 11 away from the material belt 40, so as to separate the product 41 from the material belt 40.

[0058] In some preferred embodiments, the suction cup mechanism 10 further includes a negative pressure connector 16, one end of which is connected to the suction plate 11, and the other end of which is connected to an external negative pressure source. When the suction plate 11 abuts against the product 41, the external negative pressure source is activated, so that the negative pressure medium in the external negative pressure source enters the suction plate 11 through the negative pressure connector 16, thereby enabling the suction plate 11 to pick up the product 41 and ensuring the reliability of the suction plate 11.

[0059] In some more preferred embodiments, please refer to Figure 7 , Figure 7 The diagram illustrates the structural relationship between the suction plate 11 and the elastic buffer 17 in this embodiment of the invention. Specifically, the suction cup mechanism 10 further includes the elastic buffer 17, which is connected to the side of the suction plate 11 with the suction hole 111. The elastic buffer 17 has a through hole 171 communicating with the suction hole 111. The elastic buffer 17 provides a good cushioning effect when the suction plate 11 comes into contact with the product 41, allowing the product 41 to be more securely sucked up by the suction plate 11, while avoiding damage to the product 41 when there is hard contact between the suction plate 11 and the product 41. Preferably, the elastic buffer 17 can be foam.

[0060] Example 3:

[0061] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the suction cup device of this utility model. Please refer to the appendix. Figure 8 .

[0062] The material support mechanism 30 includes a material support plate 32, which is arranged parallel to the suction plate 11, and a positioning hole 31 is formed on the material support plate 32.

[0063] In this embodiment, the material support plate 32 and the suction plate 11 are arranged parallel to each other, so that the material belt 40 and the suction plate 11 are parallel to each other. This ensures that when the suction plate 11 picks up the product 41 in the material belt 40, there is no gap between the product 41 and the suction plate 11. This avoids the problem that the product 41 cannot be accurately picked up by the suction plate 11 when there is a gap between the product 41 and the suction plate 11, thereby ensuring the reliability of the suction cup mechanism 10 and the material support mechanism 30.

[0064] In this invention, the suction cup device has a positioning component 21 located on the side of the suction plate 11 opposite to the suction hole 111 and movably inserted through the suction plate 11. The positioning drive component 22 drives the positioning component 21 to extend or retract relative to the suction plate 11. The material support mechanism 30 has a positioning hole 31 that cooperates with the positioning component 21. The material strip 40 placed on the material support mechanism 30 has an alignment hole 42 corresponding to the positioning hole 31. When the positioning component 21 extends out of the suction plate 11, the positioning component 21 passes through the alignment hole 42 and abuts against the positioning hole 31, thereby correcting the deviation of the material strip 40 so that the product 41 in the material strip 40 is centered and aligned with the suction plate 11. This ensures that the suction plate 11 can accurately pick up the product 41 in the material strip 40, avoiding the problem that the suction cup mechanism 10 cannot pick up the material normally due to the deviation of the material strip 40, thus affecting the production efficiency.
