Description

Technical Field

[0001] The present application relates to the field of sheet material adsorption, and in particular to an integrated sheet material adsorption device. Background Art

[0002] Printed circuit boards are one of the important components of electronic equipment. Almost every electronic device, including electronic watches, calculators, computers and communication electronic equipment, as long as it has electronic components such as integrated circuits, must use printed circuit boards to make electrical interconnections between the various components.

[0003] Currently, during the processing of printed circuit boards (PCBs), punching holes in the boards is necessary to facilitate positioning of the boards within electrical equipment. To facilitate the handling and transport of the boards during processing, suction devices are often used. Traditional suction devices consist of a suction rack with several small suction nozzles dispersed across it. To transport the board, the rack is controlled to move to the board, where it is then lifted up using the suction nozzles.

[0004] However, since the material sheet usually has multiple through holes on its surface after punching, when the material sheet is sucked by the suction nozzle, some of the suction nozzles will be located at the through holes of the material sheet, thereby reducing the suction force of the suction nozzles located at the through holes, making the material sheet easy to fall, thereby causing damage to the material sheet. Summary of the Invention

[0005] In order to reduce the risk of the material sheet falling during the adsorption process, the present application provides an integrated material sheet adsorption device.

[0006] This application provides an integrated sheet material adsorption device, which adopts the following technical solutions:

[0007] An integrated material sheet adsorption device includes an adsorption rack, on which an adsorption mechanism is installed, the adsorption mechanism includes an adsorption plate and an adsorption assembly, the adsorption plate is installed on the adsorption rack, and a plurality of mounting grooves are provided on the bottom wall of the adsorption plate, the adsorption assembly includes an adsorption block and an adsorption tube, the adsorption block is installed in the mounting groove, and a plurality of adsorption holes are provided on the adsorption block, the adsorption tube is installed on the adsorption plate, and one end of the adsorption tube is connected to the adsorption hole on the adsorption block, and the other end of the adsorption tube is used to connect to an external air source.

[0008] By adopting the above technical solution, a plurality of adsorption blocks are installed on the adsorption plate, so that the adsorption unit for adsorbing the material plate is integrally formed on the adsorption plate, which facilitates the control of the adsorption plate to move to the material plate and adsorb the material plate through the plurality of adsorption blocks on the adsorption plate. At the same time, because the adsorption block is also provided with a plurality of adsorption holes, even if one of the adsorption holes on the adsorption block is located at a through hole on the material plate, the other adsorption holes on the adsorption block can cover the material plate surface around the through hole, thereby increasing the adsorption capacity of the adsorption plate and facilitating the reduction of the risk of the material plate falling during the adsorption process.

[0009] In a specific embodiment, an adsorption port is provided at one end of the adsorption plate, and the adsorption port is connected to the adsorption tube. An adsorption cavity is provided in the adsorption plate, and one end of the adsorption cavity is connected to the adsorption port, and the other end is connected to the installation groove.

[0010] By adopting the above technical solution, an adsorption cavity is opened in the material plate, and an adsorption port is provided on the material plate to be connected to the adsorption tube, so that the adsorption cavity can be vacuumed through the adsorption port, thereby vacuuming the installation groove connected to the adsorption cavity, and vacuuming the adsorption holes on the adsorption block, so that the adsorption block can adsorb the material plate.

[0011] In a specific possible implementation scheme, the adsorption mechanism also includes an adsorption control component, which includes a control rod, a control head and a reset member. The control rod is installed in the adsorption hole, and one end of the control rod extends out of the adsorption hole. The control head is installed at one end of the control rod close to the adsorption hole, and the control head extends out of the adsorption hole. The side wall of the control head conflicts with the side wall of the adsorption hole. A control hole is provided on the adsorption head, and the control hole is connected to the adsorption hole. The reset member is installed in the adsorption hole, and the reset member is used to reset the control head.

[0012] By adopting the above technical solution, when the adsorption block adsorbs the material sheet, the adsorption block contacts the material sheet, causing the control head to contact the material sheet and move into the adsorption hole, thereby fully opening the adsorption hole and increasing the suction force of the adsorption hole. When the adsorption hole is located at the through hole on the material sheet, the control head does not contact the material sheet, thus keeping the adsorption hole at the through hole in a closed state, thereby increasing the adsorption force between the adsorption block and the material sheet surface.

[0013] In a specific possible implementation scheme, a guide groove is opened on the inner side wall of the adsorption hole near the adsorption head, and the inner diameter of the guide groove is larger than the outer diameter of the control head.

[0014] By adopting the above technical solution, when the control head contacts the surface of the material sheet, the control head moves into the guide groove, so that the side wall of the control head is separated from the inner wall of the adsorption hole, thereby opening the adsorption hole to facilitate adsorption of the material sheet.

[0015] In a specific possible implementation scheme, the reset member includes a reset spring, one end of the reset spring contacts the inner top wall of the guide groove, and the other end of the reset spring contacts the side wall of the control head.

[0016] By adopting the above technical solution, when the adsorption block contacts the material plate, the control head contacts the material plate and moves into the adsorption hole, thereby compressing the reset spring. When the material plate adsorption is completed, the control head is reset under the action of the reset spring, thereby continuing to close the adsorption hole.

[0017] In a specific embodiment, a sealant is filled between the outer wall of the adsorption block and the inner wall of the installation groove.

[0018] By adopting the above technical solution, sealant is filled between the outer wall of the adsorption block and the inner wall of the installation groove, thereby maintaining the sealing between the adsorption hole and the installation groove, thereby facilitating improving the airtightness of the adsorption block installed on the adsorption plate.

[0019] In a specific feasible implementation scheme, a buffer mechanism is provided on the adsorption frame, and the buffer mechanism includes a buffer plate, a buffer rod and a buffer spring. The buffer rod is slidably installed on the adsorption frame along the vertical direction, and the buffer plate is installed at the lower end of the buffer rod, and the buffer plate is connected to the adsorption plate. The buffer spring is installed on the buffer rod, and one end of the buffer spring is connected to the buffer plate, and the other end is connected to the adsorption frame.

[0020] By adopting the above technical solution, when the adsorption plate contacts the material plate, the buffer rod is driven to move upward and the buffer spring is compressed, thereby achieving buffering of the adsorption plate to facilitate adsorption of the material plate.

[0021] In a specific feasible implementation scheme, the adsorption frame is also equipped with an anti-drop mechanism, and the anti-drop mechanism includes an anti-drop plate and a connecting rod. The connecting rod is rotatably installed on the adsorption frame, one end of the connecting rod is connected to the buffer rod, and the other end of the connecting rod extends away from the adsorption frame. The anti-drop plate is rotatably installed on the adsorption frame, and one end of the anti-drop plate is connected to the end of the connecting rod away from the buffer rod, the other end of the anti-drop plate extends downward, and the end of the anti-drop plate away from the connecting rod is used to support the material plate.

[0022] By adopting the above technical solution, when the suction plate contacts the material sheet, it drives the buffer rod to move upward, thereby causing the buffer rod to drive the connecting rod to rotate, and the connecting rod drives the anti-drop plate to rotate, so that the end of the anti-drop plate away from the buffer rod rotates upward, thereby putting the anti-drop plate in an open state. After the suction plate absorbs the material sheet, the suction plate is reset under the action of the buffer spring, thereby driving the buffer rod to descend, thereby driving the connecting rod to rotate, so that the connecting rod drives the end of the anti-drop plate away from the buffer rod to rotate downward, thereby causing the anti-drop plate to retract towards the material sheet, thereby limiting the material sheet, thereby further reducing the risk of the material sheet falling.

[0023] In a specific possible implementation scheme, a detection mechanism is also installed on the adsorption frame, and the detection mechanism includes a limit switch, a detection frame and a trigger member. The detection frame is installed on the adsorption frame, the limit switch is installed on the detection frame, and the trigger member is installed on the detection frame, and the trigger member is connected to the limit switch, and the trigger member is used to contact the material plate.

[0024] By adopting the above technical solution, when the suction plate descends, the trigger member first contacts the material sheet and moves upward to trigger the limit switch, thereby facilitating the control of the suction plate to stop descending. When the trigger member triggers the limit switch, the suction plate just contacts the material sheet, thereby facilitating the suction of the material sheet.

[0025] In a specific possible implementation scheme, the trigger member includes a detection column and a detection spring, the detection column is slidably installed on the detection frame along the vertical direction, and one end of the detection column is connected to the limit switch, the detection spring is installed on the detection column, and one end of the detection spring is connected to the detection column, and the other end is connected to the detection frame.

[0026] By adopting this technical solution, when the trigger member contacts the sheet, the detection column contacts the sheet and moves upward, thereby compressing the detection spring and triggering the limit switch to control the adsorption plate to stop descending. When the sheet is lowered, the detection column returns to its original position under the action of the detection spring, allowing for the detection of a new sheet.

[0027] In summary, this application has at least one of the following beneficial effects:

[0028] 1. The present application provides an adsorption plate to facilitate adsorption of the material sheet through an integrated adsorption plate, thereby reducing the problem that the suction nozzles installed separately on the adsorption rack are located at the through holes of the material sheet, resulting in the suction nozzles at the current position being unable to adsorb the material sheet, thereby reducing the risk of the material sheet falling during the adsorption process.

[0029] 2. This application provides an adsorption control component to facilitate the control of the opening and closing of the adsorption hole through the adsorption control component, so that when the material plate is adsorbed, the adsorption plate can provide sufficient adsorption force to the material plate.

[0030] 3. This application sets up a detection mechanism to facilitate the detection of the material plate through the detection mechanism, thereby facilitating the control of the lowering distance of the adsorption plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present application is further described in detail below with reference to the accompanying drawings.

[0042] Example 1:

[0043] The embodiment of the present application discloses an integrated sheet material adsorption device, referring to Figure 1 , including a robotic arm 6 and an adsorption rack 1, the adsorption rack 1 is fixedly mounted on the robotic arm 6, and the adsorption rack 1 is mounted with an adsorption mechanism 2 and a buffer mechanism 3. A feeding device 7 is provided below the adsorption rack 1. Both the robotic arm 6 and the feeding device 7 are prior arts in the art and will not be described in detail here.

[0044] Reference Figure 1 The material sheet is transported to the bottom of the adsorption rack 1 through the feeding device 7, and the adsorption rack 1 is controlled by the robotic arm 6 to move downward to the material sheet, and is buffered by the buffer mechanism 3, and then the material sheet is sucked up by the adsorption mechanism 2, and then the adsorption rack 1 is moved to the next process through the robotic arm 6, thereby realizing the transportation of the material sheet.

[0045] Reference Figure 2 The buffer mechanism 3 includes a buffer plate 31, a buffer rod 32, and a buffer spring 33. The buffer rod 32 is slidably mounted on the adsorption rack 1 in the vertical direction, and one end of the buffer rod 32 passes through the adsorption rack 1 and extends downward. The other end of the buffer rod 32 is fixedly mounted with a positioning block 34, which contacts the top wall of the adsorption rack 1. The buffer plate 31 is fixedly mounted on the lower end of the buffer rod 32, and the buffer spring 33 is mounted on the buffer rod 32, with one end of the buffer spring 33 contacting the top wall of the buffer plate 31 and the other end contacting the bottom wall of the adsorption rack 1.

[0046] Reference Figure 3 and Figure 4 The adsorption mechanism 2 includes an adsorption plate 21 and an adsorption assembly 22. The adsorption plate 21 is fixedly installed on the bottom wall of the buffer plate 31. An adsorption port 211 is provided on the top wall of the adsorption plate 21. An adsorption cavity 212 is provided in the adsorption plate 21. The adsorption cavity 212 is connected to the adsorption port 211. A plurality of mounting grooves 213 are provided on the bottom wall of the adsorption plate 21. The mounting grooves 213 are connected to the adsorption cavity 212.

[0047] Reference Figure 4 and Figure 5 The adsorption assembly 22 includes an adsorption block 221 and an adsorption tube 222. One end of the adsorption tube 222 is fixedly connected to the top wall of the adsorption plate 21 at the adsorption port 211, and the other end is connected to an external air source. The adsorption block 221 is fixedly installed in the mounting groove 213, and one end of the adsorption block 221 extends outward from the mounting groove 213, leaving a gap between the other end and the bottom wall of the mounting groove 213. The side wall of the adsorption block 221 and the inner side wall of the mounting groove 213 are filled with sealant. A plurality of adsorption holes 2211 are opened on the bottom wall of the adsorption block 221, and the adsorption holes 2211 are connected to the mounting groove 213.

[0048] Reference Figure 1 and Figure 5The adsorption rack 1 is controlled to descend to the material sheet through the robotic arm 6, and the external air source is controlled to extract the air in the adsorption chamber 212 and the mounting groove 213 through the adsorption tube 222, so that when the adsorption block 221 contacts the material sheet, the adsorption hole 2211 maintains a vacuum between the adsorption block 221 and the material sheet, thereby adsorbing the material sheet to facilitate the transportation of the material sheet.

[0049] Reference Figure 2 , a detection mechanism 5 is also installed on the adsorption frame 1, and the detection mechanism 5 includes a limit switch 51, a detection frame 52 and a trigger 53. The detection frame 52 is fixedly installed on the bottom wall of the adsorption frame 1, and the limit switch 51 is fixedly installed on the detection frame 52. The limit switch 51 is a prior art in this field and will not be described in detail here. The trigger 53 is installed on the detection frame 52, and the trigger 53 is used to trigger the limit switch 51. The trigger 53 includes a detection column 531 and a detection spring 533. The detection column 531 is slidably installed on the detection frame 52 in the vertical direction, and one end of the detection column 531 extends downward to the bottom of the adsorption plate 21, and the other end of the detection column 531 is used to contact the limit switch 51. The detection column 531 is located on the side wall below the detection frame 52 and a limit block 532 is fixedly installed. The detection spring 533 is installed on the detection column 531, and one end of the detection spring 533 contacts the top wall of the limit block 532, and the other end contacts the bottom wall of the detection frame 52.

[0050] The working principle of the embodiment of the present application is as follows: when the material sheet is transported to the bottom of the adsorption rack 1 by the feeding device 7, the adsorption rack 1 is controlled to descend to the material sheet by the robotic arm 6. When the detection column 531 contacts the material sheet, the detection column 531 moves upward and presses the detection spring 533, and the upper end of the detection column 531 contacts the travel switch 51, thereby causing the robotic arm 6 to stop descending. At this time, the adsorption plate 21 contacts the material sheet, and the adsorption plate 21 drives the buffer plate 31 to move upward for a distance, so that the buffer plate 31 compresses the buffer spring 33 and drives the buffer rod 32 to move upward to achieve buffering. Then, the external air source is controlled to vacuum the adsorption chamber 212, the mounting groove 213 and the adsorption hole 2211 through the adsorption tube 222, so that the adsorption block 221 can adsorb the material sheet through the adsorption hole 2211. Then, the adsorption rack 1 is driven to move to the next process by controlling the robotic arm 6, thereby achieving the conveyance of the material sheet to the next process.

[0051] Example 2:

[0052] Reference Figure 6 and Figure 7The embodiment of the present application differs from the first embodiment in that the adsorption mechanism 2 further includes an adsorption control assembly 23, which includes a control rod 232, a control head 231, and a reset member. The control head 231 is slidably mounted within the adsorption hole 2211, and one end of the control head 231 extends outward from the adsorption hole 2211. The side wall of the control head 231 abuts against the inner side wall of the adsorption hole 2211. A control hole 2311 is defined on the side wall of the control head 231 located outside the adsorption hole 2211, and the control hole 2311 is connected to the adsorption hole 2211. One end of the control rod 232 is fixedly mounted on the side wall of the control head 231 located within the adsorption hole 2211, and the other end extends away from the control head 231. A guide groove 2212 is provided on the inner wall of the adsorption hole 2211 near the control head 231 . The inner diameter of the guide groove 2212 is larger than the outer diameter of the control head 231 . The reset member is installed in the guide groove 2212 and is used to control the reset of the control head 231 .

[0053] Reference Figure 6 The reset member includes a reset spring 233, which is installed on the control rod 232, and one end of the reset spring 233 is in conflict with the side wall of the control head 231 located in the adsorption hole 2211, and the other end is in conflict with the inner top wall of the guide groove 2212 away from the control head 231.

[0054] Reference Figure 7 When the adsorption plate 21 moves downward to contact the material plate, the adsorption block 221 also contacts the material plate, causing the control head 231 to contact the material plate and move into the adsorption hole 2211 into the guide groove 2212, thereby compressing the return spring 233, so that the side wall of the control head 231 is separated from the side wall of the adsorption hole 2211, thereby opening the adsorption hole 2211, thereby increasing the adsorption force of the adsorption block 221 on the material plate, so as to facilitate the material plate to be sucked up. When the adsorption block 221 moves to the through hole on the material plate, the individual adsorption holes 2211 on the adsorption block 221 coincide with the through hole. At this time, the control head 231 remains separated from the material plate, so that the control head 231 keeps the adsorption hole 2211 located at the through hole in a closed state, so that the suction force in other adsorption holes 2211 on the same adsorption block 221 increases, thereby facilitating the adsorption block 221 to adsorb the surface around the through hole on the material plate through other adsorption holes 2211, thereby improving the problem that the through hole position of the material plate cannot be adsorbed, and reducing the risk of the material plate falling during the adsorption process.

[0055] Reference Figure 8The adsorption rack 1 is also equipped with an anti-drop mechanism 4, which includes an anti-drop plate 41 and a connecting rod 42. The connecting rod 42 is rotatably mounted on the bottom wall of the adsorption rack 1, and one end of the connecting rod 42 extends to the buffer rod 32, and the other end extends away from the buffer rod 32. A push rod 321 is fixedly mounted on the side wall of the buffer rod 32, and a first waist-shaped hole 421 is opened at one end of the connecting rod 42 close to the buffer rod 32, and the push rod 321 is slidably mounted in the first waist-shaped hole 421. A second waist-shaped hole 422 is provided at one end of the connecting rod 42 away from the buffer rod 32, and the anti-drop plate 41 is rotatably mounted on the bottom wall of the adsorption frame 1, and a guide rod is fixedly mounted on one end of the anti-drop plate 41, and the guide rod is slidably mounted in the second waist-shaped hole 422, and the other end of the anti-drop plate 41 extends downward to the bottom of the adsorption plate 21, and the end of the anti-drop plate 41 away from the guide rod is used to support the material plate. The anti-drop plate 41 is made of thermoplastic plastic, and the end of the anti-drop plate 41 away from the guide rod is bent toward the direction of the adsorption plate 21.

[0056] The working principle of the embodiment of the present application is as follows: when the adsorption rack 1 drives the adsorption plate 21 to move downward until it contacts the material sheet, the sidewall of the curved end of the anti-drop plate 41 contacts the material sheet. Since the anti-drop plate 41 is made of thermoplastic material, it slides along the surface of the material sheet while the adsorption plate 21 moves downward and deforms until the anti-drop plate 41 separates from the material sheet, at which point the anti-drop plate 41 recovers its deformation. At the same time, the adsorption plate 21 drives the buffer rod 32 upward via the buffer plate 31, thereby driving the connecting rod 42 to rotate via the push rod 321, causing the connecting rod 42 to drive the end of the anti-drop plate 41 away from the connecting rod 42 to rotate upward, thereby causing the anti-drop plate 41 to be in an open state. At the same time as the adsorption plate 21 contacts the material sheet, the control head 231 on the adsorption block 221 contacts the material sheet and moves into the adsorption hole 2211, causing the control head 231 to compress the return spring 233 and open the adsorption hole 2211, thereby allowing the adsorption block 221 to complete the adsorption of the material sheet. Then the robotic arm 6 controls the adsorption rack 1 to rise, thereby driving the adsorption plate 21 to rise, so that the adsorption plate 21 drives the buffer rod 32 to move downward to reset through the buffer plate 31, thereby driving the connecting rod 42 to rotate through the push rod 321, so that the connecting rod 42 drives the anti-drop plate 41 away from one end of the connecting rod 42 to rotate downward to the bottom of the material plate, thereby supporting the material plate, making it easier to prevent the material plate from falling.

[0057] When the robotic arm 6 transports the material sheet to another process, the robotic arm 6 drives the adsorption rack 1 to move downward, thereby placing the material sheet in the next process, and drives the buffer rod 32 to move upward through the buffer plate 31, thereby achieving buffering. At the same time, the buffer rod 32 drives the connecting rod 42 to rotate through the push rod 321, so that the connecting rod 42 drives the anti-drop plate 41 to rotate upward away from one end of the connecting rod 42, thereby making the anti-drop plate 41 in an open state, so that the adsorption plate 21 can release the material sheet.

[0058] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
