Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit board manufacturing, and in particular to a clamping mechanism, a circuit board clamping device and a clamping method. BACKGROUND

[0002] In the manufacturing process of printed circuit boards (PCBs), there are multiple links such as design, plate making, assembly, testing and cleaning. Among them, the cleaning link is crucial to ensuring the quality of the finished PCBs. By effectively removing the oil stains, dust and chemical reagents left over in the production process, the circuit boards can ensure stable electrical performance and reliability.

[0003] At present, the finished PCBs show a clear miniaturization trend. This miniaturization trend greatly reduces the edge size of the finished products, and the mechanical clamping system of the cleaning jig using the up-down pressing clamping method has a minimum clamping margin of ≥3mm for most products, which cannot adapt to the advanced design with an edge size of <0.5mm.

[0004] In view of the above problems, a device capable of clamping the circuit board laterally to facilitate cleaning has been proposed. However, this device has the problems of complex structure and large size, which will occupy too much space on the cleaning equipment, thereby reducing the number of circuit boards that can be cleaned at one time and lowering the cleaning efficiency.

[0060] In the description of the embodiments of the application, unless otherwise expressly specified and limited, the technical term "contact" should be understood in a broad sense, which can be direct contact or contact through an intermediate medium layer, which can be contact between two objects in contact without interaction force, or contact between two objects in contact with interaction force.

[0061] In the related art, a clamping device is provided, which can laterally clamp a circuit board to facilitate cleaning, but it needs a special driving member to realize clamping driving, and the clamping structure is relatively complex, resulting in high cost and large size, which will occupy too much space on the cleaning equipment, thereby reducing the number of circuit boards that can be cleaned at the same time, and reducing the cleaning efficiency.

[0062] For this purpose, reference is made to Figures 1-11The embodiment of the present application provides a circuit board 10 clamping device, which comprises a clamping mechanism 200 and a moving mechanism 100. Figure 1 And Figure 2 The clamping mechanism 200 is used for clamping the circuit board 10, and the moving mechanism 100 can move relative to the clamping mechanism 200, so as to move the circuit board 10 to the clamping mechanism 200 or take away the circuit board 10 on the clamping mechanism 200.

[0063] The clamping mechanism 200 comprises a clamping module 210, and the number of the clamping module 210 can be one or multiple.

[0064] The clamping module 210 comprises a fixed part 211, a movable part 212, a second connecting part 214 and an elastic part 215.

[0065] The movable part 212 can move towards the fixed part 211 to a first position or move away from the fixed part 211 to a second position. The movable part 212 in the first position cooperates with the fixed part 211 to clamp the side of the circuit board 10, and the movable part 212 in the second position releases the clamping of the circuit board 10, so as to facilitate the moving mechanism 100 to take away the circuit board or facilitate the moving mechanism 100 to place the circuit board 10 between the movable part 212 and the fixed part 211.

[0066] The second connecting part 214 is connected with the movable part 212, and both of them move relative to the fixed part 211. The second connecting part 214 is configured to be connected with the first connecting part 110, and after the connection, the movable part 212 can be moved to the second position by the moving mechanism 100. During the movement of the movable part 212 to the second position, the elastic part 215 is compressed to store power.

[0067] When the movable part 212 is in the second position, the first connecting part 110 of the moving mechanism 100 moves and is separated from the second connecting part 214, and after the separation, the elastic part 215 releases the elastic force to make the movable part 212 move to the first position and cooperate with the fixed part 211 to clamp the side of the circuit board 10.

[0068] In the above embodiment, the first connecting part 110 of the moving mechanism 100 is connected with the second connecting part 214 of the clamping module 210, so as to drive the movable part 212 to move to the second position, and after the first connecting part 110 is separated from the second connecting part 214, the elastic force provided by the elastic part 215 cooperates with the fixed part 211 to clamp the side of the circuit board 10. Since the movement of the moving mechanism 100 drives the movable part 212 to move to the second position, the clamping mechanism 200 does not need to be provided with a driving structure, the number of parts is reduced, the cost is reduced, and the volume of the clamping module 210 is reduced, so that more clamping modules 210 can be arranged during cleaning, so as to improve the cleaning efficiency.

[0069] Please refer to Figure 1 In some embodiments, the moving mechanism 100 includes a pick-and-place section 120 connected to a first connecting section 110, which allows the pick-and-place section 120 to move along with the first connecting section 110. Please refer to... Figure 7 , Figure 7 The movable component 212 moves to the second position. When the movable component 212 is in the second position, the pick-and-place section 120 moves between the movable component 212 and the fixed component 211 to place or remove the circuit board 10. In this way, the movement of the movable component 212 and the movement of the pick-and-place section 120 are carried out simultaneously, and when the movable component 212 moves to the second position, the pick-and-place section 120 moves between the movable component 212 and the fixed component 211, which can improve the efficiency of the pick-and-place section 120 in placing or removing the circuit board 10, shorten the loading and unloading time, and realize the rapid connection of the cleaning process.

[0070] Please refer to Figure 1 and Figure 2 The specific structure of the first connecting part 110 and the second connecting part 214 is not limited; for example, a snap-fit ​​structure can be used.

[0071] In some embodiments, one of the first connecting portion 110 and the second connecting portion 214 is a connecting hole, and the other is a pin. The first connecting portion 110 and the second connecting portion 214 are inserted into each other along a first direction. This first direction can be perpendicular to the large surface of the circuit board 10. The engagement of the connecting hole and the pin results in a simple overall structure and convenient separation. For example, the first connecting portion 110 is a pin with an inclined tapered guide surface at its front end, and the second connecting portion 214 is a connecting hole. The pin can be telescopically designed to avoid rigid collision with the connecting hole through telescopic movement.

[0072] In some embodiments, the pick-and-place section 120 includes a negative pressure suction port connected to a negative pressure source to provide negative pressure to adsorb the circuit board 10 or to release the negative pressure to place the circuit board 10.

[0073] The pick-and-place unit 120 can move together with the first connecting part 110 along a first direction, so that the negative pressure suction port can move closer to the fixing member 211 to pick up or place the circuit board 10, or move away from the fixing member 211. Thus, during the process of establishing a connection between the first connecting part 110 and the second connecting part 214, the negative pressure suction port can move closer to the fixing member 211 to facilitate the placement or removal of the circuit board 10, improving efficiency. The pick-and-place unit 120 may be equipped with an active lifting drive unit to move the circuit board 10, or it may not be equipped with such a unit and can rely on the lifting of the moving mechanism 100 itself.

[0074] Please refer to Figure 3 and Figure 4In some embodiments, the fixing member 211 includes intersecting first support bar 2111 and second support bar 2112, and the movable member 212 includes intersecting third support bar 2121 and fourth support bar 2122. The first support bar 2111 and the third support bar 2121 are disposed opposite each other, and the second support bar 2112 and the fourth support bar 2122 are disposed opposite each other. A placement station is defined between the first support bar 2111, the second support bar 2112, the third support bar 2121, and the fourth support bar 2122 for placing the circuit board 10.

[0075] The angle at which the first support bar 2111 and the second support bar 2112 intersect is determined according to the circuit board 10. Taking a rectangular circuit board 10 as an example, the first support bar 2111 and the second support bar 2112 form an L-shaped intersection structure, abutting against two adjacent sides of the circuit board 10 respectively. Similarly, the third support bar 2121 and the fourth support bar 2122 form an L-shaped intersection structure, abutting against the other two adjacent sides of the circuit board 10 respectively. In this way, the lateral displacement of the circuit board 10 can be restricted from multiple dimensions, improving the stability of clamping to adapt to cleaning conditions.

[0076] Please refer to Figure 3 and Figure 4 In some embodiments, the fixing member 211 includes a plurality of first supporting portions 2113 protruding toward the movable member 212. The first supporting portions 2113 are used to support the side of the circuit board 10, and there is a first interval 2114 between adjacent first supporting portions 2113 for the flow of cleaning fluid. By supporting the side of the circuit board 10 with the above-mentioned plurality of first supporting portions 2113, a multi-point supporting structure can be formed to avoid the problem of supporting stability affected by flatness when supporting surfaces, thereby improving stability. In addition, the cleaning fluid can flow out through the above-mentioned first interval 2114, which can increase the flow rate of the cleaning fluid, improve the cleaning effect, and also increase the outflow rate of the cleaning fluid after cleaning, thus shortening the cleaning cycle.

[0077] In some embodiments, the movable member 212 includes a plurality of second supporting portions 2123 protruding toward the fixed member 211. The second supporting portions 2123 are used to support the side of the circuit board 10, and there is a second interval 2124 between adjacent second supporting portions 2123 for the flow of cleaning fluid. By supporting the side of the circuit board 10 with the above-mentioned plurality of second supporting portions 2123, a multi-point supporting structure can be formed to avoid the problem of supporting stability affected by flatness when supporting surface to surface, thereby improving stability. In addition, the cleaning fluid can flow out through the above-mentioned second interval 2124, which can increase the flow rate of the cleaning fluid, improve the cleaning effect, and also increase the outflow rate of the cleaning fluid after cleaning, thus shortening the cleaning cycle.

[0078] For example, the first support bar 2111 and the third support bar 2121 are used to clamp the relatively long side of the circuit board 10, and the second support bar 2112 and the fourth support bar 2122 are used to clamp the relatively short side of the circuit board 10. The first support bar 2111 and the second support bar 2112 have a first supporting portion 2113, and the third support bar 2121 and the fourth support bar 2122 have a second supporting portion 2123. The first supporting portion 2113 of the first support bar 2111 has the same size as the second supporting portion 2123 of the third support bar 2121, and the first supporting portion 2113 of the second support bar 2112 has the same size as the second supporting portion 2123 of the fourth support bar 2122.

[0079] The size of the first supporting portion 2113 of the first support bar 2111 is the same as or different from the size of the first supporting portion 2113 of the second support bar 2112. For example, the size of the first supporting portion 2113 of the first support bar 2111 is larger than the size of the first supporting portion 2113 of the second support bar 2112.

[0080] In some embodiments, the direction of action of the elastic element 215 intersects with the extension direction of the first support bar 2111 or the second support bar 2112.

[0081] Taking the example where the direction of action of the elastic element 215 intersects with the extension direction of the first support bar 2111, the first support bar 2111 and the third support bar 2121 can clamp the two sides of the circuit board 10. The extension directions of the second support bar 2112 and the fourth support bar 2122 do not intersect with the direction of force of the elastic element 215, so they mainly serve to limit the circuit board 10.

[0082] In other embodiments, the direction of action of the elastic element 215 intersects the extending directions of both the first support bar 2111 and the second support bar 2112. In this case, the first support bar 2111 and the third support bar 2121 can clamp opposite sides of the circuit board 10, while the second support bar 2112 and the fourth support bar 2122 clamp the other two opposite sides of the circuit board 10. This allows all four sides of the circuit board 10 to be clamped, thereby improving clamping stability.

[0083] For example, please refer to Figure 2 The clamping module 210 also includes a guide housing 216, and an elastic element 215 is disposed within the guide housing 216. Please refer to... Figure 4The movable member 212 includes a third supporting portion 2125, which has a notch with an arc-shaped inner wall. The third supporting portion 2125 is also disposed within the guide housing 216. The elastic member 215 is formed by elastically bending a metal sheet. The middle part of the elastic member 215 supports the inner wall of the notch, and the two ends of the elastic member 215 are bent to form a support structure, which is supported on the guide housing 216. Thus, when the movable member 212 moves toward the second position, the elastic member 215 is compressed and stores force. When the first connecting portion 110 separates from the second connecting portion 214, the elastic member 215 releases force and acts on the movable member 212, causing it to move toward the first position.

[0084] The movable component 212 includes a third support bar 2121, a fourth support bar 2122, and a connecting bar 2126. The fourth support bar 2122 is connected to one end of the third support bar 2121, and the connecting bar 2126 is connected to the other end of the third support bar 2121, with its extension direction opposite to that of the fourth support bar 2122. A third supporting portion 2125 is connected to the connecting bar 2126, and a second connecting portion 214 is disposed at the connection between the connecting bar 2126 and the third supporting portion 2125.

[0085] Please refer to Figure 4 In some embodiments, a placement station is defined between the fixing member 211 and the movable member 212 for placing the circuit board 10. The clamping mechanism 200 also includes a support member 213, which is located at the placement station and connected to the fixing member 211. The support member 213 is provided with a plurality of mesh holes for the flow of cleaning fluid. In this way, the circuit board 10 is supported without obstructing the flow of cleaning fluid.

[0086] The support member 213 and the fixing member 211 can be directly connected or indirectly connected through other components. The exemplary support member 213 includes a frame and a mesh plate. The mesh plate is disposed within the frame and has a plurality of mesh holes evenly distributed thereon to facilitate the flow of cleaning fluid.

[0087] Please refer to Figure 5 In some embodiments, the number of clamping modules 210 is multiple. The clamping mechanism 200 also includes a clamping disk 220, on which multiple clamping modules 210 are spaced apart. The multiple clamping modules 210 clamp the circuit board 10, and then the clamping mechanism 200 that clamps the multiple circuit boards 10 is placed on a cleaning device for cleaning. Because the clamping mechanism 200 has a simple structure and small size, the number of clamping modules 210 provided on the clamping disk 220 can be increased, thereby improving cleaning efficiency.

[0088] The orientation of each clamping module 210 is consistent, which makes the moving direction of the movable parts 212 of each clamping module 210 consistent, so as to facilitate the simultaneous driving of all movable parts 212.

[0089] This application embodiment also provides a clamping mechanism 200, please refer to... Figures 1-4 The device includes a clamping module 210, which comprises a fixing member 211, a movable member 212, a second connecting portion 214, and an elastic member 215. The movable member 212 can move toward the fixing member 211 to a first position to engage with the fixing member 211 and clamp the side of the circuit board 10, or move away from the fixing member 211 to a second position to release the clamping of the circuit board 10. The second connecting portion 214 is connected to the movable member 212 and is configured to connect with a moving mechanism 100, allowing the movable member 212 to be moved to the second position by the moving mechanism 100, or to be separated from the moving mechanism 100. The elastic member 215 is configured to provide an elastic force that allows the movable member 212 to engage with the fixing member 211 and clamp the circuit board 10 when the second connecting portion 214 is separated from the moving mechanism 100. The specific structure of the clamping mechanism 200 is the same as that of the circuit board 10 clamping device described above.

[0090] Please refer to Figure 1 , Figures 6-11 This application also provides a circuit board clamping method, applicable to circuit board clamping devices, the circuit board clamping method including:

[0091] The moving mechanism carrying the circuit board is controlled to move, so that the first connecting part is connected to the second connecting part.

[0092] Control the movement of the moving mechanism carrying the circuit board, so that the moving part follows and moves to the second position.

[0093] After the circuit board is placed between the movable part and the fixed part, the moving mechanism is controlled to move so that the first connecting part and the second connecting part are separated, and the elastic part makes the movable part and the fixed part cooperate to clamp the circuit board.

[0094] The circuit board is carried by the pick-and-place unit, and after the movable part moves to the second position, the pick-and-place unit places it between the movable part and the fixed part.

[0095] The position at which the first connecting portion and the second connecting portion separate is not limited.
