Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing, and in particular to a circuit board extraction device and circuit board extraction equipment. Background Technology

[0002] The manufacturing process of circuit boards is complex. During the production of circuit boards, they often need to be transferred to different processes for processing. Therefore, the efficiency of circuit board transfer has a significant impact on the overall production efficiency of the circuit board production line.

[0003] Currently, when using a regular suction cup to pick up a circuit board, a blank area without any surface mount components or holes is required on the surface of the circuit board. Therefore, when designing a circuit board, it is necessary to consider reserving enough blank area without surface mount components or holes. On the one hand, this increases the design difficulty of the circuit board, and on the other hand, it increases the size of the circuit board, thus increasing the design and manufacturing cost of the circuit board. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies cannot extract areas including holes on circuit boards. This invention provides a circuit board extraction device capable of extracting areas with holes on circuit boards without requiring blank areas, resulting in more compact and smaller circuit boards, thus reducing costs.

[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a circuit board extraction device, comprising:

[0006] Connector for connecting to a vacuum device;

[0007] A suction cup for picking up circuit boards, the suction cup including a first cavity, the first cavity being in communication with the connector;

[0008] A positioning part, at least a portion of which is disposed in the first cavity, the positioning part including a hollow cavity and a positioning structure, the hollow cavity communicating with the connector, and the portion of the hollow cavity communicating with the first cavity, the positioning structure protruding from one end of the positioning part and extending out of the first cavity for insertion into the hole of the circuit board.

[0009] Using the above technical solution, the circuit board extraction device includes a positioning part, and the hollow cavity of the positioning part can connect the connector and the first cavity of the suction cup, thereby enabling the first cavity to be evacuated to a vacuum state, allowing the suction cup to pick up the circuit board. A positioning structure is also provided at one end of the positioning part, extending out of the first cavity and capable of being inserted into the hole of the circuit board. When it is necessary to extract the circuit board, simply insert the positioning structure into the hole of the circuit board, and the vacuum device is activated to evacuate the first cavity to a vacuum state to extract the circuit board. On the one hand, it is not necessary to avoid the holes of the circuit board to achieve the extraction of the circuit board, eliminating the need to leave blank areas on the circuit board, allowing for a more compact and smaller circuit board, which helps reduce the cost of the circuit board; on the other hand, because the positioning structure is inserted into the hole of the circuit board, it can limit the swaying of the circuit board on the horizontal plane during the transfer process, preventing excessive swaying that could cause the circuit board to fall off the suction cup, reduce production efficiency, or even damage the circuit board.

[0010] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a circuit board extraction device, wherein the positioning part includes a connecting hole, the hollow cavity extends along a first direction, the end of the hollow cavity near the connector has an opening, the connector and the hollow cavity are connected through the opening, the connecting hole is provided in the portion of the hollow cavity in the first cavity, and the first cavity and the hollow cavity are connected through the connecting hole.

[0011] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a circuit board extraction device, wherein the positioning part includes a blocking part, and the blocking part is spaced apart from the opening along the first direction, the connecting hole is disposed between the blocking part and the opening, the blocking part forms the bottom wall of the hollow cavity, and is used to seal the end of the hollow cavity away from the opening, and the positioning structure protrudes from the side of the blocking part facing away from the hollow cavity.

[0012] By adopting the above technical solution, by setting a sealing part, which forms the bottom wall of the hollow cavity, it is possible to further ensure good sealing between the first cavity and the circuit board, and enhance the stability of the suction cup in picking up the circuit board.

[0013] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a circuit board extraction device, wherein the positioning part is detachably connected to the connector, and the positioning structure includes a mounting groove for mounting and dismounting the positioning part.

[0014] Using the above technical solution, the positioning part and the connector can be detachably connected, which facilitates the installation and maintenance of the circuit board extraction device. For example, if the positioning part or the connector is damaged, the damaged part can be directly replaced without affecting the normal operation of other components.

[0016] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a circuit board extraction device, wherein the positioning part has an open end with a thread, and the positioning part is threadedly connected to the plug connector.

[0017] Using the above technical solution, the positioning part is threadedly connected to the connector. By inserting a tool (such as a screwdriver) into the mounting slot through the hole in the circuit board and rotating it, the positioning part and the connector can be installed or removed.

[0018] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a circuit board extraction device, wherein the suction cup is made of an elastic material and includes a plurality of bent portions, the plurality of bent portions being connected sequentially along a first direction, the bending directions of two adjacent bent portions being opposite, and each bent portion being able to switch between a compressed state and an uncompressed state.

[0019] Using the above technical solution, when a circuit board needs to be picked up, the vacuum device puts the first cavity into a vacuum state. At this time, the bent part is in a compressed state, and the suction cup can hold the circuit board, making it easy to transfer the circuit board. When the circuit board is transferred to the target area, the vacuum state of the first cavity is released, and the bent part returns to an uncompressed state, making it easy to release the circuit board from the suction cup.

[0020] The present invention also discloses a circuit board extraction device, which includes at least the circuit board extraction device and a vacuum device as described in any of the above embodiments, wherein the vacuum device is connected to the connector of the circuit board extraction device.

[0021] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a circuit board extraction device, including a fixing plate, the fixing plate including a plurality of mounting holes, each mounting hole corresponding to a circuit board extraction device, the suction cup of the circuit board extraction device being disposed between the fixing plate and the circuit board along a first direction, and the connector and positioning part of the circuit board extraction device being disposed at both ends of the mounting hole.

[0022] Using the above technical solution, the circuit board extraction device includes a fixing plate with multiple mounting holes.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] See Figure 1 This application provides a circuit board extraction device, including a circuit board extraction unit 10 and a vacuum device (not shown in the figure), wherein the vacuum device is connected to the circuit board extraction unit 10. Exemplarily, the vacuum device includes an air pipe (not shown in the figure), and the circuit board extraction unit 10 is connected to the vacuum device through the air pipe. It is understood that the vacuum device may be a vacuum pump, and this application does not limit it to this.

[0036] In some embodiments, see Figure 1 , Figure 2 The circuit board extraction device includes a fixing plate 20, which has multiple mounting holes 21, each corresponding to a circuit board extraction device 10. For example, the fixing plate 20 has three mounting holes 21, and correspondingly, the circuit board extraction device includes three circuit board extraction devices 10.

[0037] In some embodiments, see Figure 1 , Figure 2 , Figure 3The circuit board extraction device 10 includes a connector 11, a suction cup 12, and a positioning part 13. The connector 11 is used to communicate with a vacuum device. Exemplarily, the connector 11 includes a connection hole 111 for inserting a tube from the vacuum device. The suction cup 12 is used to pick up the circuit board 30. The suction cup 12 includes a first cavity 121, which communicates with the connector 11, meaning the vacuum device can use the connector 11 to bring the first cavity 121 into a vacuum state or a non-vacuum state. Exemplarily, along the first direction Z, the suction cup 12 is positioned between the fixing plate 20 and the circuit board 30, and the connector 11 and positioning part 13 of the circuit board extraction device 10 are located at both ends of the mounting hole 21. Figure 2 As shown, the connector 11, mounting hole 21, and positioning part 13 are assembled together along the dotted line a.

[0038] In some embodiments, see Figure 1 , Figure 2 , Figure 3 At least a portion of the positioning part 13 is disposed in the first cavity 121. The positioning part 13 includes a hollow cavity 131 and a positioning structure 132. The hollow cavity 131 communicates with the connector 11, and a portion of the hollow cavity 131 communicates with the first cavity 121. The positioning structure 132 protrudes from one end of the positioning part 13 and extends out of the first cavity 121 for insertion into the hole 301 of the circuit board 30. For example, the positioning part 13 may be a hollow positioning pin.

[0039] Using the above technical solution, the circuit board 30 extraction device 10 includes a positioning part 13, and the hollow cavity 131 of the positioning part 13 can connect the connector 11 and the first cavity 121 of the suction cup 12, thereby enabling the first cavity 121 to be drawn into a vacuum state so that the suction cup 12 can pick up the circuit board 30. A positioning structure 132 is also provided at one end of the positioning part 13, which extends out of the first cavity 121 and can be inserted into the hole 301 of the circuit board 30. When it is necessary to extract the circuit board 30, simply insert the positioning structure 132 into the hole 301 of the circuit board 30, and the vacuum device will be activated to evacuate the first cavity 121 to a vacuum state to extract the circuit board 30. On the one hand, it is not necessary to avoid the hole 301 of the circuit board 30 to extract the circuit board 30. There is no need to leave a blank area on the circuit board 30, which makes the circuit board 30 more compact and smaller in size, which helps to reduce the cost of the circuit board 30. On the other hand, since the positioning structure 132 is inserted into the hole 301 of the circuit board 30, it can limit the shaking of the circuit board 30 on the horizontal plane during the transfer of the circuit board 30, preventing the circuit board 30 from shaking too much on the horizontal plane and falling off the suction cup 12, reducing production efficiency or even damaging the circuit board 30.

[0040] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The positioning part 13 includes a connecting hole 133. A hollow cavity 131 extends along a first direction Z. The end of the hollow cavity 131 near the connector 11 has an opening 1311. The connector 11 communicates with the hollow cavity 131 through the opening 1311. The connecting hole 133 is located in the portion of the hollow cavity 131 in the first cavity 121. The first cavity 121 communicates with the hollow cavity 131 through the connecting hole 133. Exemplarily, two connecting holes 133 are spaced apart on the sidewall 1312 of the hollow cavity 131. It is understood that the number of connecting holes 133 in this embodiment is not limited. For example, it can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.

[0041] For example, see Figure 3 , Figure 4 When it is necessary to transfer circuit board 30, the vacuum device is activated, and the gas in the first chamber 121 flows along... Figure 4 Arrow b passes through the connecting hole 133, the hollow cavity 131, and the connector 11 in sequence, so that the first cavity 121 is in a vacuum state. The suction cup adheres to the surface 302 of the circuit board 30 and holds the circuit board 30, which facilitates the transfer of the circuit board 30 to the target area.

[0042] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The positioning part 13 includes a sealing part 134. Along the first direction Z, the sealing part 134 and the opening 1311 are spaced apart. A connecting hole 133 is provided between the sealing part 134 and the opening 1311. The sealing part 134 forms the bottom wall 1313 of the hollow cavity 131 and is used to seal the end of the hollow cavity 131 away from the opening 1311. The side of the sealing part 134 facing away from the hollow cavity 131 abuts against the surface 302 of the circuit board 30. The positioning structure 132 protrudes from the side of the sealing part 134 facing away from the hollow cavity 131 and is inserted into the hole 301 of the circuit board 30. For example, the sealing part 134 is fitted to the side wall 1312 of the hollow cavity 131. When the side wall 1312 of the hollow cavity 131 is annular, the sealing part 134 is cylindrical. The shape of the hollow cavity 131 is not limited in this embodiment. For example, it can also be cuboid. When the side wall 1312 of the hollow cavity 131 is cuboid, the sealing part 134 is cuboid.

[0043] For example, the sealing part 134 is integrally formed with the side wall 1312 of the hollow cavity 131. By providing the sealing part 134, the sealing part 134 forms the bottom wall 1313 of the hollow cavity 131, which can further ensure good sealing between the first cavity 121 and the circuit board 30, and enhance the stability of the suction cup 12 in picking up the circuit board 30.

[0044] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 , the positioning portion 13 is detachably connected to the plug connector 11. The positioning structure 132 includes a mounting groove 1321 for assembling and disassembling the positioning portion 13. Exemplarily, one end of the positioning portion 13 provided with an opening 1311 includes a thread, and the positioning portion 13 is threadedly connected to the plug connector 11. In some embodiments, the mounting groove 1321 includes a slotted cross recess or a Phillips recess. Exemplarily, the mounting groove 1321 extends perpendicular to the first direction Z and penetrates the entire positioning structure 132. It can be understood that the shape of the mounting groove 1321 is not limited in the embodiments of the present application. For example, it can also be a shape like a cross recess. The positioning structure 132 is provided in the cavity of the circuit board 30, and limits the circuit board 30 in a direction perpendicular to the first direction Z (such as the second direction Y). A tool (such as a screwdriver) can be inserted through the hole 301 of the circuit board 30 into the mounting groove 1321 and rotated to achieve the installation or disassembly of the positioning portion 13 and the plug connector 11.

[0045] In some embodiments, the mounting hole 21 of the mounting plate includes a thread, the plug connector 11 is threadedly connected to one end of the mounting hole 21, and the positioning portion 13 is threadedly connected to one end of the mounting hole 21. At this time, the plug connector 11 and the positioning portion 13 are respectively detachably inserted into both ends of the mounting hole 21, which can further facilitate the installation and disassembly operations.

[0046] In some embodiments, referring to Figure 2 , Figure 3 , Figure 5 , the suction cup 12 is made of an elastic material. The suction cup 12 includes a plurality of bending portions 122. The plurality of bending portions 122 are sequentially connected along the first direction Z and jointly enclose a first cavity 121. The bending directions of adjacent two bending portions 122 are opposite, and each bending portion 122 can switch between a compressed state and a non-pressed state.

[0047] For example, along the first direction Z, the suction cup 12 includes a first bent portion 1221, a second bent portion 1222, and a third bent portion 1223 connected in sequence. The second bent portion 1222 is disposed between the first bent portion 1221 and the third bent portion 1223. The first bent portion 1221 and the third bent portion 1223 are recessed towards the positioning portion 13 along the second direction Y. The second bent portion 1222 protrudes outward along the second direction Y towards the side away from the positioning portion 13. When it is necessary to pick up the circuit board 30, the vacuum device puts the first cavity 121 into a vacuum state. At this time, the first bent portion 1221, the second bent portion 1222, and the third bent portion 1223 are in a compressed state, and the suction cup 12 can pick up the circuit board 30, which facilitates the transfer of the circuit board 30. When the circuit board 30 is transferred to the target area, the vacuum state of the first cavity 121 is released, and the first bending part 1221, the second bending part 1222 and the third bending part 1223 return to the unpressurized state, so that the circuit board 30 can be released from the suction cup 12.

[0048] Understandably, the number of bends 122 is not limited in the embodiments of this application. For example, it can be 1, 2, 4, 5, 6, 7, etc.

[0049] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
