Description

Technical Field

[0001] This invention relates to the field of circuit board manufacturing technology, and in particular to a clamping mechanism, a circuit board clamping device, and a clamping method. Background Technology

[0002] The manufacturing process of printed circuit boards (PCBs) encompasses multiple stages, including design, board fabrication, assembly, testing, and cleaning. Among these, the cleaning stage is crucial for ensuring the quality of the finished PCB. By effectively removing residual oil, dust, and chemical reagents from the production process, the PCB can be guaranteed to have stable electrical performance and reliability.

[0003] Currently, finished PCB products are showing a clear trend towards miniaturization. This miniaturization trend has led to a significant reduction in the margin size of finished products. However, traditional mechanical clamping systems for cleaning fixtures that use top and bottom clamping methods, with a minimum clamping margin of ≥3mm for most products, are no longer suitable for advanced designs with margins of <0.5mm.

[0004] To address the aforementioned issues, a technical solution has proposed a device capable of laterally clamping circuit boards for easier cleaning. However, this device suffers from a complex structure and large size, which consumes excessive space on the cleaning equipment, thereby reducing the number of circuit boards that can be cleaned simultaneously and lowering cleaning efficiency. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a clamping mechanism, a circuit board clamping device, and a clamping method, which can facilitate the cleaning of circuit boards with small margin dimensions, and has a simple structure and small size.

[0006] According to a first aspect of the present invention, a circuit board clamping device includes a clamping mechanism and a moving mechanism;

[0007] The moving mechanism is movable relative to the clamping mechanism, and the moving mechanism includes a first connecting portion;

[0008] The clamping mechanism includes a clamping module, the clamping module comprising:

[0009] Fasteners;

[0010] The movable component can move toward the fixing component to a first position to cooperate with the fixing component to clamp the side of the circuit board, or move away from the fixing component to a second position to release the clamping of the circuit board;

[0011] A second connecting portion is connected to the movable member. The second connecting portion is configured to connect with the first connecting portion so that the movable member can be moved to the second position by the moving mechanism, or separated from the first connecting portion.

[0012] An elastic element is configured to provide an elastic force that causes the movable element to engage with the fixed element and clamp the circuit board when the first connecting portion is separated from the second connecting portion.

[0013] The circuit board clamping device according to embodiments of the present invention has at least the following advantages: The first connecting portion of the moving mechanism is connected to the second connecting portion of the clamping module, thereby driving the movable member to move to a second position. After the first connecting portion and the second connecting portion separate, an elastic member provides elastic force to clamp the movable member and the fixed member on the side of the circuit board. Since the moving mechanism is used to move the movable member to the second position, the clamping mechanism does not need a drive structure, reducing the number of parts, lowering costs, and reducing the volume of the clamping module. This allows for the installation of more clamping modules during cleaning, thereby improving cleaning efficiency.

[0014] According to some embodiments of the present invention, the moving mechanism includes a pick-and-place section connected to the first connecting section. When the movable member is in the second position, the pick-and-place section moves between the movable member and the fixed member to place or remove the circuit board.

[0024] The clamping mechanism also includes a support member, which is located at the placement station and connected to the fixing member. The support member is provided with a plurality of mesh holes for the flow of cleaning fluid.

[0025] According to some embodiments of the present invention, the number of clamping modules is multiple;

[0026] The clamping mechanism also includes a clamping disk, and multiple clamping modules are spaced apart on the clamping disk.

[0030] A second connecting portion is connected to the movable member. The second connecting portion is configured to connect to a moving mechanism so that the movable member can be moved to the second position by the moving mechanism, or separated from the moving mechanism.

[0031] An elastic element is configured to provide an elastic force that causes the movable element to engage with the fixed element and clamp the circuit board when the second connection portion is separated from the moving mechanism.

[0061] In related technologies, a clamping device is provided that can laterally clamp circuit boards to facilitate cleaning. However, it requires a special driving component to achieve clamping drive, and the clamping structure is relatively complex, resulting in high cost and large size. This will cause it to 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 cleaning efficiency.

[0062] Please refer to the following for details. Figures 1-11This application provides a circuit board 10 clamping device, including a clamping mechanism 200 and a moving mechanism 100. Please refer to... Figure 1 and Figure 2 The clamping mechanism 200 is used to clamp the circuit board 10, and the moving mechanism 100 is movable relative to the clamping mechanism 200 to move the circuit board 10 to the clamping mechanism 200 or remove the circuit board 10 from the clamping mechanism 200.

[0063] The clamping mechanism 200 includes clamping modules 210, and the number of clamping modules 210 can be one or more.

[0064] The clamping module 210 includes a fixing member 211, a movable member 212, a second connecting part 214, and an elastic member 215. The moving mechanism 100 includes a first connecting part 110.

[0065] The movable member 212 can move toward the fixed member 211 to a first position, or move away from the fixed member 211 to a second position. In the first position, the movable member 212 cooperates with the fixed member 211 to clamp the side of the circuit board 10. In the second position, the movable member 212 releases the clamp on the circuit board 10, thereby facilitating the moving mechanism 100 to remove the circuit board, or facilitating the moving mechanism 100 to place the circuit board 10 between the movable member 212 and the fixed member 211.

[0066] The second connecting part 214 is connected to the movable part 212, and the two move together relative to the fixed part 211. The second connecting part 214 is configured to connect with the first connecting part 110. After connection, the movable part 212 can be moved to the second position by the moving mechanism 100. During the process of the movable part 212 moving to the second position, the elastic member 215 is compressed and stores force.

[0067] When the movable part 212 is in the second position, the first connecting part 110 of the moving mechanism 100 moves and separates from the second connecting part 214. After separation, the elastic part 215 releases force so that the movable part 212 moves to the first position and cooperates with the fixing part 211 to clamp the circuit board 10.

[0068] In the above embodiment, the first connecting portion 110 of the moving mechanism 100 is connected to the second connecting portion 214 of the clamping module 210, thereby driving the movable part 212 to move to the second position. After the first connecting portion 110 and the second connecting portion 214 are separated, the elastic member 215 provides elastic force and cooperates with the fixing member 211 to clamp the circuit board 10 on the side. Since the moving mechanism 100 is used to move the movable part 212 to the second position, the clamping mechanism 200 does not need to be equipped with a drive structure, reducing the number of parts, lowering costs, and reducing the volume of the clamping module 210. This allows for the installation of more clamping modules 210 during cleaning, thereby improving 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 movement of the moving mechanism carrying the circuit board is controlled to connect the first connecting part with 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.
