Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to a support mechanism that facilitates stable support of PCB boards. Background Technology

[0002] As a core component of electronic devices, the production process of PCB boards involves multiple complex and delicate steps. In order to ensure production efficiency and product quality, the transfer links between different processes are quite important. During the transfer process, special carriers are usually used to carry the PCB boards to protect them from damage, and the transfer of PCB boards is achieved by moving the carriers.

[0003] A common approach is to create slots in the carrier to accommodate the edges of a PCB board. However, the width of the slot is fixed, while the thickness of the PCB board varies depending on the electronic device being manufactured. When a thinner PCB board is placed in a slot of fixed width, the PCB board may wobble in the slot because the slot width is greater than the board thickness, causing deformation during transit. If slots of different thicknesses are used, the production cost will be higher. Utility Model Content

[0004] The main purpose of this utility model is to propose a support mechanism that can stably support PCB boards, aiming to solve the technical problem of not being able to support PCB boards of different thicknesses.

[0005] To achieve the above objectives, the present invention proposes a support mechanism for facilitating stable support of a PCB board, comprising:

[0006] The supporting body includes a first supporting structure and a second supporting structure connected to each other. Positioning grooves are provided on both the first and second supporting structures, respectively used to support the side and bottom edges of the PCB board.

[0007] An elastic component is disposed within the positioning groove, and the elastic component is used to abut against the PCB board within the positioning groove.

[0008] In one embodiment, multiple support plates are provided at intervals in the first support structure and the second support structure, and each support plate is provided with multiple positioning grooves at intervals along its length.

[0009] In one embodiment, multiple elastic components are provided, and at least one elastic component is provided in each positioning groove.

[0010] In one embodiment, the resilient component includes:

[0011] The mounting plate is located on the side of the support plate away from the load-bearing body and is adjacent to the corresponding positioning groove;

[0012] Connect the connecting plate assembly to the mounting plate;

[0013] The pressure plate is connected to the side of the connecting plate assembly away from the mounting plate and extends toward the bottom wall of the positioning groove;

[0014] The elastic component is elastic, so that the PCB board is pressed against the side wall of the positioning groove within the positioning groove.

[0015] In one embodiment, the connecting plate assembly includes:

[0016] The first plate is connected to the mounting plate and extends in a direction away from the support plate;

[0017] The second plate is connected to the end of the first plate away from the mounting plate. The second plate is parallel to the mounting plate and extends in a direction away from the mounting plate.

[0018] The third plate has one end connected to the pressure plate and the other end connected to the end of the second plate away from the first plate. The third plate is inclined to form a guide portion.

[0019] In one embodiment, the elastic component is made of any one of spring steel, phosphor bronze, beryllium copper, and stainless steel.

[0020] In one embodiment, the elastic component has a protective layer on its outer periphery.

[0021] In one embodiment, the protective layer is made of any one of Teflon, hard chrome plating, and graphite coating.

[0022] In one embodiment, the second load-bearing structure includes a support frame and a first mounting frame disposed on the support frame, wherein the first mounting frame is inclined on the side away from the support frame;

[0023] The first load-bearing structure includes a connecting frame and a second mounting frame disposed on the connecting frame.

The second mounting frame is inclined on the side away from the connecting frame, and the angle between the second mounting frame and the first mounting frame is a right angle.

[0024] The support plates are respectively mounted on the first mounting frame and the second mounting frame.

[0026] In the technical solution of this utility model, the support mechanism includes a bearing body and an elastic component. The bearing body includes a first bearing structure and a second bearing structure, which are respectively used to support the side and bottom edge of the PCB board. Positioning grooves are provided on the first and second bearing structures, and elastic components are correspondingly provided on the positioning grooves. The elastic components are positioned within the positioning grooves and form a clamping space with one side wall of the positioning groove. When the PCB board is inserted into the clamping space, due to the elasticity of the elastic component, the PCB board compresses the elastic component, causing the elastic component to rebound and press the PCB board firmly against the side wall of the positioning groove. When a thinner PCB board is placed in the positioning groove, the elastic component can adjust its elasticity according to the thickness of the PCB board to ensure that the PCB board does not wobble. For thicker PCB boards, the elastic component can also provide sufficient clamping force to prevent displacement or wobbling during transfer, thus improving the stability of the bearing and transfer. Furthermore, the elastic component can be used for PCB boards of different thicknesses without changing the support mechanism or adjusting the width of the positioning groove, thus ensuring stable transport of PCB boards of different thicknesses and improving PCB board production efficiency.

[0042] A common approach is to create slots in the carrier to accommodate the edges of a PCB board. However, the width of the slot is fixed, while the thickness of the PCB board varies depending on the electronic device being manufactured. When a thinner PCB board is placed in a slot of fixed width, the PCB board may wobble in the slot because the slot width is greater than the board thickness, causing deformation during transit. If slots of different thicknesses are used, the production cost will be higher.

[0043] This utility model proposes a support mechanism that facilitates stable support of PCB boards.

[0044] Please see Figure 1 In one embodiment of this utility model, the support mechanism 20 includes:

[0045] The supporting body 100 includes a first supporting structure 110 and a second supporting structure 120 connected to each other. Positioning grooves 301 are respectively provided on the first supporting structure 110 and the second supporting structure 120, and the positioning grooves 301 on the first supporting structure 110 and the second supporting structure 120 are respectively used to support the side and bottom edges of the PCB board; and

[0046] The elastic component 200 is disposed in the positioning groove 301 and is used to abut against the PCB board in the positioning groove 301.

[0047] In the technical solution of this utility model, the support mechanism 20 includes a bearing body 100 and an elastic component 200. The bearing body 100 includes a first bearing structure 110 and a second bearing structure 120, which are respectively used to support the side and bottom edge of the PCB board. Positioning grooves 301 are respectively provided on the first bearing structure 110 and the second bearing structure 120, and elastic components 200 are correspondingly provided on the positioning grooves 301. The elastic components 200 are correspondingly disposed within the positioning grooves 301, forming a clamping space within the positioning grooves 301. When the PCB board is inserted into the clamping space, due to the elasticity of the elastic component 200, the PCB board... The elastic component 200 causes compression, and the elastic component 200 rebounds, pressing the PCB board firmly into the positioning groove 301. When a thinner PCB board is placed into the positioning groove 301, the elastic component 200 can adjust the elastic force according to the thickness of the PCB board to ensure that the PCB board does not wobble. For thicker PCB boards, the elastic component 200 can also provide sufficient clamping force to prevent the PCB board from shifting or wobbling during transfer, thus improving the stability of load transfer. Moreover, the setting of the elastic component 200 can be used for PCB boards of different thicknesses. Without changing the support mechanism 20 or adjusting the width of the positioning groove 301, PCB boards of different thicknesses can be transported stably, thus improving the production efficiency of PCB boards.

[0048] Specifically, please refer to Figure 3 The support mechanism 20 is used for a board handling equipment. The board handling equipment includes a housing 10, which houses a robotic arm and a transport mechanism. At least one set of processing stations is also provided within the housing 10. A carrier moves to the processing station via an AGV (Automated Guided Vehicle) trolley, waiting for the robotic arm to transfer the PCB boards transported from the previous process to the support mechanism 20, or to transfer the PCB boards from the support mechanism 20 to the transport mechanism for transport to the next process. For example, Figure 1 As shown, the support mechanism 20 includes a first bearing structure 110 and a second bearing structure 120 connected to each other. One end of the first bearing structure 110 and one end of the second bearing structure 120 are connected and form a 90° angle. The materials of the first bearing structure 110 and the second bearing structure 120 are not limited. The PCB board is placed vertically on the support mechanism 20. The side of the first bearing structure 110 facing the second bearing structure 120 is configured as the first contact surface, and the side of the second bearing structure 120 facing the first bearing structure 110 is configured as the second contact surface. Positioning grooves 301 are respectively provided on the first contact surface and the second contact surface, and the positioning grooves 301 on the first contact surface correspond to the positioning grooves 301 on the second contact surface, and are used to clamp the side and bottom edge of the PCB board respectively. The first bearing structure 110 and the second bearing structure 120 can be connected by bolts, welding or integral molding to ensure the overall stability. The connection method is not limited here. Each positioning slot 301 has an elastic component 200. Specifically, one elastic component 200 can be placed in each positioning slot 301, cooperating with the side wall of the positioning slot 301 to form a stable clamping structure. The elastic component 200 is used to abut against the PCB board and clamp the PCB board by cooperating with the side wall of the positioning slot 301. Alternatively, one elastic component 200 can be placed near each of the two side walls in the positioning slot 301, so that a clamping space is formed between the two elastic components 200. This allows the two elastic components 200 to clamp the two sides of the PCB board, preventing it from shaking during transit. That is, regardless of the thickness of the PCB board, when the PCB board is placed in the positioning slot 301, it compresses the elastic component 200, thus ensuring the elastic component 200 remains in place. The elastic component 200 springs back and presses the PCB board firmly against the side wall of the positioning groove 301, thus fixing the PCB board and preventing it from shaking within the positioning groove 301. The elastic component 200 can be made of materials such as rubber, which can maintain good elasticity even after long-term use. The selection of the material of the elastic component 200 must not only ensure sufficient clamping force when it comes into contact with the PCB board, but also avoid excessive pressure on the PCB board to prevent damage. The matching of the load-bearing body 100 and the elastic component 200 ensures the stability of the PCB board during the transfer process. In addition, the elastic component 200 also has a certain buffering effect, which can protect the PCB board from impacts or vibrations, ensuring that its electrical performance and mechanical strength are not damaged.

[0049] In the embodiments of this utility model, a plurality of support plates 300 are respectively provided at intervals in the first support structure 110 and the second support structure 120, and each support plate 300 is provided with a plurality of positioning grooves 301 at intervals along its length direction.

[0050] Please refer to Figure 1 The first support structure 110 is vertically arranged, and multiple support plates 300 are arranged at intervals along the vertical direction on the first support structure 110. The second support structure 120 is horizontally arranged, and correspondingly, multiple support plates 300 are arranged at intervals on the second support structure 120. The direction of the interval arrangement of the support plates 300 on the second support structure 120 is from the end of the second support structure 120 closest to the first support structure 110 to the end furthest from the first support structure 110. Positioning grooves 301 are arranged on the support plates 300. Multiple positioning grooves 301 are arranged at intervals on the support plates 300, which can support multiple PCB boards at the same time, and different PCB boards do not contact each other, which can also avoid collisions between PCB boards. In addition, multiple support plates 300 can be arranged to accommodate PCB boards of different lengths and widths, making it more applicable and allowing PCB boards of different sizes to be positioned.

[0051] In one embodiment, such as Figure 2 As shown, a number mark 400 is provided on the support plate 300, and the number mark 400 corresponds to the positioning slot 301 to mark the number of positioning slots 301. The number mark 400 is numbered according to the arrangement order of the positioning slots 301. In this embodiment, the number mark 400 starts from "1" and increments, so that the operator can quickly identify and locate the position of each positioning slot 301, improving the placement efficiency and inspection efficiency of the PCB board. The number mark 400 can be set on the support plate 300 by laser engraving.

[0052] In one embodiment, multiple elastic components 200 are provided, and each positioning groove 301 is provided with at least one elastic component 200, that is, each positioning groove 301 can support PCB boards of different thicknesses, thereby reducing production costs.

[0053] In an embodiment of this utility model, the elastic component 200 includes:

[0054] Mounting plate 210 is located on the side of support plate 300 away from the main body 100 and is adjacent to the corresponding positioning groove 301;

[0055] Connecting plate assembly 220 is connected to mounting plate 210;

[0056] The pressure plate 230 is connected to the side of the connecting plate assembly 220 away from the mounting plate 210 and extends toward the bottom wall of the positioning groove 301;

[0057] The elastic component 200 is elastic so that the PCB board is pressed against the side wall of the positioning groove 301 within the positioning groove 301.

[0058] Please refer to Figure 2 The elastic component 200 includes a mounting plate 210, a connecting plate assembly 220, and a pressure plate 230. A support plate 300 protrudes between adjacent positioning grooves 301. The mounting plate 210 is mounted on the support plate 300 with screws and is adjacent to the corresponding positioning groove 301. The connecting plate assembly 220 is mounted on the side of the mounting plate 210 facing the positioning groove 301. The connecting plate assembly 220 is connected to the pressure plate 230. The pressure plate 230 forms a clamping action between itself and the side wall of the positioning groove 301 within the positioning groove 301. In the space, the PCB board is inserted into the clamping space, and the PCB board contacts the pressure plate 230, which squeezes the pressure plate 230 toward the side wall on the other side, causing the pressure plate 230 to deform. The pressure plate 230 has a tendency to rebound, causing the PCB board to be pressed toward the side wall, thereby fixing the PCB board. The elastic components 200 on the first bearing structure 110 and the elastic components 200 on the second bearing structure 120 clamp the side plate and bottom plate of the PCB board respectively, making the PCB board more stable on the support mechanism 20.

[0059] In an embodiment of this utility model, the connecting plate assembly 220 includes:

[0060] The first plate 221 is connected to the mounting plate 210 and extends in a direction away from the support plate 300;

[0061] The second plate 222 is connected to the end of the first plate 221 away from the mounting plate 210. The second plate 222 is parallel to the mounting plate 210 and extends in a direction away from the mounting plate 210.

[0062] The third plate 223 has one end connected to the pressure plate 230 and the other end connected to the end of the second plate 222 away from the first plate 221. The third plate 223 is inclined to form a guide portion.

[0063] Please refer to Figure 2 The connecting board assembly 220 includes a first board 221, a second board 222, and a third board 223 connected in sequence. The first board 221 is connected to the mounting plate 210 and extends upward. The second board 222 is horizontally arranged and is located on both sides of the first board 221, respectively, along with the mounting plate 210. The third board 223 is inclined and is connected to the second board 222 at one end and to the pressure plate 230 at the other end. The inclined arrangement of the third board 223 facilitates the insertion of the PCB board and makes it easier for the PCB board to be inserted into the clamping space formed by the pressure plate 230 and the side wall of the positioning groove 301.

[0064] In one embodiment, the connection between the third plate 223 and the pressure plate 230 is provided with rounded corners to prevent the PCB board from being scratched at the connection between the third plate 223 and the pressure plate 230 in the insertion clamping space. The rounded corners can make it easier to insert the PCB board and reduce the friction during insertion.

[0065] In one embodiment, the elastic component 200 is made of any one of spring steel, phosphor bronze, beryllium copper, and stainless steel, all of which have good elasticity. Spring steel also has good wear resistance. Under long-term use, it can provide elasticity to abut against the PCB board and maintain a good surface condition. The spring steel can be high carbon steel, alloy spring steel, etc., to avoid scratching the PCB board. There are no restrictions on the material of the elastic component 200, as long as it can provide good elasticity to abut against the PCB board in the positioning groove 301.

[0066] In an embodiment of this utility model, a protective layer is provided on the outer periphery of the elastic component 200. The protective layer can reduce the surface roughness of the elastic component 200, thereby reducing the friction between the elastic component 200 and the PCB board. This not only facilitates the insertion of the PCB board, but also avoids scratching the PCB board.

[0067] In one embodiment, the protective layer is made of any one of Teflon, hard chrome plating, and graphite coating. Teflon, also known as polytetrafluoroethylene, has a smooth surface and an extremely low coefficient of friction. The Teflon coating can be sprayed onto the surface of the elastic component 200 to reduce its surface coefficient of friction. Alternatively, an electroplating process can be used to generate a coating on the surface of the elastic component 200. The coating material is hard chrome, which has high hardness and wear resistance, and can significantly reduce roughness, so that the coefficient of friction can reach below 0.1 μm. Nickel plating or copper plating can also be used. Nickel plating requires a bright nickel process to obtain a smooth surface, so that the coefficient of friction is between 0.05-0.2 μm. In addition, the surface of the elastic component 200 can be polished to reduce the coefficient of friction of the surface of the elastic component 200.

[0068] In an embodiment of the present invention, the second bearing structure 120 includes a support frame 121 and a first mounting frame 122 disposed on the support frame 121, wherein the first mounting frame 122 is inclined on the side away from the support frame 121.

[0069] The first load-bearing structure 110 includes a connecting frame 111 and a second mounting frame 112 disposed on the connecting frame 111. The support frame 121 is connected to the connecting frame 111 and is set at an angle. The second mounting frame 112 is set at an angle on the side away from the connecting frame 111, and the angle between the second mounting frame 112 and the first mounting frame 122 is a right angle.

[0070] The support plates 300 are respectively mounted on the first mounting frame 122 and the second mounting frame 112.

[0071] Please refer to Figure 1 The support frame 121 is horizontally set on other placement platforms. The connecting frame 111 is set on the support frame 121, and can be set at a 90° angle or an obtuse angle with the support frame 121. A first mounting frame 122 is inclinedly set on the support frame 121. The top end of the first mounting frame 122 near the connecting frame 111 is lower than the end away from the connecting frame 111. A second mounting frame 112 is inclinedly set on the connecting frame 111. The distance between the end of the second mounting frame 112 near the support frame 121 and the connecting frame 111 is greater than the distance between the end away from the support frame 121, so that the first mounting frame 122 and the second mounting frame 112 are at a 90° angle. This makes the PCB board also tilted in the positioning groove 301, which can prevent the PCB board from slipping on the open side during the transfer process and improve the stability of the transfer and transportation.

[0072] In one embodiment, the second supporting structure 120 further includes a plurality of pads 123, which are disposed between the support frame 121 and the first mounting frame 122. The height of the pads 123 increases from the end of the support frame 121 near the connecting frame 111 to the end away from the connecting frame 111. Please refer to [reference needed]. Figure 1 The progressively increasing height of the pads 123 can provide progressive support for the first mounting bracket 122, ensuring the stability of the first mounting bracket 122 when tilted. In another embodiment, a single pad 123 can be provided, extending from the end near the connecting bracket 111 towards the end away from the connecting bracket 111, with progressively increasing height. This can also provide progressive support for the first mounting bracket 122. The spaced arrangement of multiple pads 123, compared to continuous pads 123, can reduce the weight of the entire support mechanism 20.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
