Description

PCB board receiving mechanism Technical Field

[0001] This utility model relates to the field of circuit board storage technology, and in particular to a PCB board receiving mechanism. Background Technology

[0002] Storage and transfer are indispensable parts of the printed circuit board (PCB) production process. However, the industry currently uses stacked storage and transfer. But because PCBs come into contact with each other during stacking, friction and collision between the boards can easily occur, causing scratches. This not only affects the appearance quality of the PCBs, but may also lead to electrical performance problems such as short circuits and open circuits, thus affecting the reliability and service life of the products. Summary of the Invention

[0003] The main purpose of this invention is to propose a PCB board receiving mechanism, which aims to avoid damage caused by friction and collision between PCB boards during PCB storage and transfer.

[0007] A clamping assembly is provided on the mounting bracket. The clamping assembly includes multiple clamping structures, each of which is provided with a first positioning slot to clamp the PCB board when the PCB board is placed in the first positioning slot.

[0008] In one embodiment, the mounting bracket includes a first plate and a second plate, the first plate and the second plate are connected, and the first fixing plate and the second fixing plate are respectively disposed on the first plate and the second plate to cooperate in clamping the adjacent sides of the PCB board;

[0009] The first plate is used on one side of the first fixing plate, and it is inclined from the side away from the second plate to the side closer to the second plate, with the inclined surface facing away from the second plate; the second plate is used on the side where the second fixing plate is installed, and it is inclined from the side away from the first plate to the side closer to the first plate, with the inclined surface facing the first plate.

[0013] In one embodiment, the clamping assembly further includes a support frame extending along the first direction and mounted on the first plate, and a plurality of the clamping structures are spaced apart from the support frame along the first direction.

[0014] In one embodiment, the clamping structure includes:

[0015] A fixing part is provided on the support frame;

[0016] The positioning part is installed on the fixing part;

[0017] The clamping part is hinged to the positioning part via a first pivot.

[0018] A first elastic element is sleeved on the first rotating shaft and abuts against the side of the clamping part facing the positioning part, so that the end of the clamping part away from the fixing part has a tendency to rotate away from the positioning part.

[0019] The limiting part is hinged to the clamping part via a second rotating shaft, and the limiting part and the clamping part are detachably connected to have a first state and a second state;

[0020] In the first state, the limiting part and the positioning part are engaged at the end away from the fixing part, so that there is a gap between the end of the clamping part near the fixing part and the fixing part. In the second state, the limiting part is disengaged from the positioning part, and the first elastic member drives the end of the clamping part away from the fixing part to rotate in a direction away from the positioning part, and causes the end of the clamping part near the fixing part to move towards the fixing part, so as to clamp the PCB board.

This can both position the PCB board and prevent the PCB board surfaces from contacting each other, thus avoiding damage to the PCB board. In addition, a clamping component is also provided on one side of the mounting frame. The clamping component is used to clamp the PCB board, which can prevent the PCB board from swinging and causing position changes, so that the PCB board maintains a vertical and consistent reference position, avoiding deviations in the board removal position in subsequent processes, eliminating the need to spend extra time adjusting the board or removing the board, and improving work efficiency.

[0041] This utility model proposes a PCB board receiving mechanism.

[0042] Please refer to Figures 1 and 2. In one embodiment of this utility model, the PCB winding mechanism includes:

[0043] Mounting bracket 100;

[0044] A storage component 200 is mounted on a mounting bracket 100. The storage component 200 includes a first fixing plate 210 and a second fixing plate 220. The first fixing plate 210 has a plurality of first positioning grooves 211 spaced apart along a first direction, and the second fixing plate 220 has a plurality of second positioning grooves 221 spaced apart along the first direction. Each first positioning groove 211 and each second positioning groove 221 are correspondingly arranged. The first positioning grooves 211 and the second positioning grooves 221 are respectively used to support adjacent sides of the PCB board 10.

[0045] The clamping assembly 300 is disposed on the mounting bracket 100. The clamping assembly 300 includes a plurality of clamping structures 320. Each clamping structure 320 is provided with a first positioning groove 211 to clamp the PCB board 10 when the PCB board 10 is placed in the first positioning groove 211.

[0046] In the technical solution of this utility model, the board receiving mechanism includes a mounting frame 100, on which a storage component 200 is provided. The storage component 200 includes a first fixing plate 210 and a second fixing plate 220. A plurality of first positioning grooves 211 are provided on the first fixing plate 210, and a plurality of second positioning grooves 221 are provided on the second fixing plate 220. The first positioning grooves 211 and the second positioning grooves 221 are respectively used to position and support both sides of the PCB board 10, and the two sides are adjacent to each other. Since the plurality of first positioning grooves 211 are spaced apart, and each first positioning groove 211 corresponds to a... The second positioning slot 221 keeps each PCB board 10 in a separated state, which can both position the PCB board 10 and prevent the board surfaces of the PCB boards 10 from contacting each other, thus avoiding damage to the PCB boards 10. In addition, a clamping component 300 is provided on one side of the mounting bracket 100. The clamping component 300 is used to clamp the PCB board 10, which can prevent the PCB board 10 from swinging and causing position changes, so that the PCB board 10 maintains the same vertical reference position, avoiding deviation in the board removal position in subsequent processes, eliminating the need to spend extra time adjusting the board or removing the board, and improving work efficiency.

[0047] Specifically, the mounting bracket 100 is L-shaped. The material of the mounting bracket 100 is not limited. The PCB board 10 includes a first side and a second side opposite to each other, as well as a top edge and a bottom edge opposite to each other. A first fixing plate 210 is provided on the vertical side of the mounting bracket 100, and a second fixing plate 220 is provided on the horizontal side. The first fixing plate 210 has multiple first positioning grooves 211 spaced apart along its length, and the second fixing plate 220 has multiple second positioning grooves 221 spaced apart along its length. Each first positioning groove 211 and each second positioning groove 221 are correspondingly arranged. When the PCB board 10 is placed on the mounting bracket 100, its first side edge is confined within the first positioning groove 211, and its bottom edge is confined within the second positioning groove 221. By setting the first positioning groove 211 and the second positioning groove 221, the multiple PCB boards 10 on the mounting frame 100 can be supported without contacting each other, thus avoiding damage to the PCB boards 10. The width of the first positioning groove 211 and the second positioning groove 221 is greater than that of the PCB board 10, which facilitates the placement of the PCB board 10. In order to prevent the PCB board 10 from shaking and causing changes in its spacing, which would affect the subsequent board retrieval process, a clamping component 300 is set on the mounting frame 100. The clamping component 300 is set corresponding to the first fixing groove, which can firmly clamp the PCB board 10 after it is placed in, effectively preventing unnecessary movement of the PCB board 10 during storage and ensuring the consistency of the position each time the board is retrieved.

[0048] In an embodiment of this utility model, the mounting bracket 100 includes a first plate 110 and a second plate 120, the first plate 110 and the second plate 120 are connected, and a first fixing plate 210 and a second fixing plate 220 are respectively disposed on the first plate 110 and the second plate 120 to cooperate in clamping the adjacent sides of the PCB board 10.

[0049] The first plate 110 is used on one side of the first fixing plate 210, and it is inclined from the side away from the second plate 120 toward the side closer to the second plate 120, with the inclined surface facing away from the second plate 120; the second plate 120 is used on the side where the second fixing plate 220 is installed, and it is inclined from the side away from the first plate 110 toward the side closer to the first plate 110, with the inclined surface facing the first plate 110.

[0050] Specifically, referring to Figure 1, one side of the first plate 110 is fixedly connected to one side of the second plate 120 in an "L" shape, preferably integrally formed. The first plate 110 is vertically arranged, and the second plate 120 is horizontally arranged. A first fixing plate 210 is provided on the side of the first plate 110 facing the second plate 120, which extends horizontally. A second fixing plate 220 is provided on the side of the second plate 120 facing upward, which also extends horizontally. The second fixing plate 220 is used to arrange multiple PCB boards 10 at intervals in the horizontal direction, and each PCB board 10 is placed vertically. It should be noted that the opposite sides of the first plate 110 and the second plate 120 are both tilted towards the side away from each other, so that the bottom edge of the PCB board 10 is in an inclined state, and the end closer to the first plate 110 is lower than the end away from the first plate 110. This can further limit the PCB board 10 and prevent it from falling off the mounting bracket 100.

[0051] Specifically, the lower end of the first plate 110 is inclined towards the upper end, which can be understood as the thickness of the upper end of the first plate 110 being less than the thickness of the lower end. The end of the second plate 120 closest to the first plate 110 is inclined towards the end furthest from the first plate 110, which can be understood as the thickness of the end of the second plate 120 closest to the first plate 110 being less than the thickness of the end of the first plate 110. In one embodiment, the first plate 110 includes a vertically arranged first plate 111 and an inclined second plate 112, and the second plate 120 includes a horizontally arranged third plate 121 and an inclined fourth plate 122. The first plate 111 and the third plate 121 are vertically connected. The upper end of the board 112 is fixedly connected to the first board 111, and the lower end is inclined and connected to the third board 121. The end of the fourth board 122 near the first board 110 is connected to the second board 112 at a 90° angle, and the other end is inclined upward and connected to the third board 121 through a mounting block. This makes the 90° angle between the second board 112 and the fourth board 122 lower than the end of the fourth board 122 away from the first board 110. The first fixing plate 210 is horizontally mounted on the second board 112, and the second fixing plate 220 is horizontally mounted on the fourth board 122. This makes the PCB board 10 not only able to be stored without contact but also inclined towards the angle, making the storage more stable.

[0052] In an embodiment of this utility model, a plurality of first fixing plates 210 are provided, and the plurality of first fixing plates 210 are spaced apart along the first plate 110 from the side away from the second plate 120 toward the side closer to the second plate 120; a plurality of second fixing plates 220 are provided, and the plurality of second fixing plates 220 are spaced apart along the second plate 120 from the side away from the first plate 110 toward the side closer to the first plate 110.

[0053] Specifically, referring to Figure 1, the first fixing plate 210 extends horizontally and is arranged vertically at intervals on the first plate 110. Correspondingly, the second fixing plate 220 extends horizontally and is arranged vertically at intervals on the second plate 120. The first positioning groove 211 and the second positioning groove 221 are correspondingly arranged, and the PCB board 10 is positioned through the first positioning groove 211 and the second positioning groove 221. In addition, by setting multiple first fixing plates 210 and multiple second fixing plates 220, PCB boards 10 of different lengths and heights can be accommodated. Figure 1 shows two different sizes of PCB boards 10. If the PCB board 10 is a small PCB board, its length and height are both small, so that its first side and bottom edge cannot contact the first fixing plate 210 and the second fixing plate 220 which are far apart. In this case, it can be positioned and clamped by the first fixing plate 210 near the second plate 120 and the second fixing plate 220 near the first plate 110. If the PCB board 10 is a large PCB board, its first side edge can be positioned by a plurality of first positioning grooves 211 spaced apart in the vertical direction, and its bottom edge can be positioned by a plurality of second positioning grooves 221 spaced apart in the horizontal direction, which has a wider range of applications.

[0054] It should be noted that the clamping component 300 is set on the first plate 110 and is set on the first fixing plate 210 which is close to the second plate 120. As long as the PCB board 10 can be positioned in the first positioning groove 211, it can be clamped by the clamping component 300. This avoids the PCB board 10 being unable to contact the first fixing plate 210 which is far from the second plate 120 when it is not clamped. It can achieve positioning and clamping of PCB boards 10 of any size.

[0055] In an embodiment of this utility model, the first positioning groove 211 is located away from the end of the first plate 110, and its two sides are inclined in a direction away from each other.

[0056] Specifically, please refer to Figure 2. The length of the first positioning groove 211 extends along the width of the first fixing plate 210. The bottom of the first positioning groove 211 is parallel to the first fixing plate 210. The groove walls on both sides extend outward near the opening. That is, the distance between the two groove walls at the opening is greater than the width of the bottom of the groove, so that the cross section of the first positioning groove 211 is set in a "U" shape, which facilitates the guidance of the PCB board 10 and allows it to slide smoothly into the first positioning groove 211.

[0057] In an embodiment of this utility model, one side wall of the second positioning groove 221 is inclined in a direction away from the other side wall.

[0058] Specifically, referring to Figure 2, the first positioning groove 211 extends along the width of the second fixing plate 220 in the length direction. One side of the groove wall is parallel to the height direction of the second fixing plate 220 and can be used as a reference for bottom edge positioning. The other side of the groove wall is inclined and extends away from the side wall parallel to the height direction of the second fixing plate 220. The inclined groove wall can guide the PCB board 10, allowing it to slide smoothly into the second positioning groove 221. Since the inclined surface is in contact with one side of the bottom edge of the PCB board 10, the inclined surface makes the PCB board 10 tend to move closer to the other side of the groove wall, which helps to maintain the vertical state of the PCB board 10. This ensures that all the stored PCB boards 10 have the same reference, which facilitates the consistency of board retrieval in subsequent processes.

[0059] In an embodiment of the present invention, the clamping assembly 300 further includes a support frame 310, which extends along a first direction and is mounted on the first plate 110. A plurality of clamping structures 320 are spaced apart on the support frame 310 along the first direction.

[0060] Specifically, referring to Figures 1 and 3, the support frame 310 is disposed on the second plate 112 and extends horizontally. Its two ends are fixedly connected to the second plate 112, and the support frame 310 is disposed adjacent to the first fixing plate 210 of the second plate 120. Multiple clamping structures 320 are disposed horizontally at intervals on the support frame 310. Each clamping structure 320 is disposed corresponding to a first positioning groove 211, so that when the PCB board 10 is positioned in one or more first positioning grooves 211, its corresponding clamping structure 320 clamps the PCB board 10 to prevent the PCB board 10 from swinging.

[0061] In one embodiment, the clamping structures 320 are staggered on the support frame 310.

[0062] Specifically, since the PCB board 10 is relatively thin, the width of the first positioning groove 211 and the second positioning groove 221 is relatively narrow. In order to save space, multiple PCB boards 10 can be stored on the mounting bracket 100. Therefore, the spacing between adjacent first positioning grooves 211 on the first fixing plate 210 needs to be set accordingly. The smaller the spacing, the more PCB boards 10 can be stored. However, the small spacing between adjacent first positioning grooves 211 makes it impossible to install clamping structures 320. By arranging multiple rows of clamping structures 320 at intervals along the vertical direction on the support bracket 310, and arranging each row of clamping structures 320 at intervals in the horizontal direction, as shown in the figure, the clamping structures 320 are staggered so that each first positioning groove 211 has a clamping structure 320 corresponding to it. In this embodiment, two rows of clamping structures 320 are arranged along the vertical direction on the support bracket 310. The upper row of clamping structures 320 and the lower row of clamping structures 320 are staggered and adjacent to each other to avoid the narrow distance affecting the clamping of the PCB board 10 by the adjacent clamping structures 320.

[0063] In an embodiment of this utility model, the clamping structure 320 includes:

[0064] The fixing part 321 is provided on the support frame 310;

[0065] Positioning part 322 is installed on fixing part 321;

[0066] The clamping part 323 is hinged to the positioning part 322 via a first rotating shaft 328;

[0067] The first elastic element 324 is sleeved on the first rotating shaft 328 and abuts against the side of the clamping part 323 facing the positioning part 322, so that the end of the clamping part 323 away from the fixing part 321 has a tendency to rotate away from the positioning part 322.

[0068] The limiting part 325 is hinged to the clamping part 323 via the second rotating shaft 329. The limiting part 325 and the clamping part 323 are detachably connected to have a first state and a second state.

[0069] In the first state, the limiting part 325 and the positioning part 322 are engaged at the end away from the fixing part 321, so that there is a gap between the end of the clamping part 323 near the fixing part 321 and the fixing part 321. In the second state, the limiting part 325 and the positioning part 322 are disengaged, and the first elastic member 324 drives the end of the clamping part 323 away from the fixing part 321 to rotate in the direction away from the positioning part 322, and causes the end of the clamping part 323 near the fixing part 321 to move toward the fixing part 321, so as to clamp the PCB board 10.

[0070] Specifically, referring to Figures 4, 5, and 6, the first plate 110 is hollow. Both ends of the support frame 310 are fixed to the first plate 110. The clamping structure 320 includes a fixing part 321, a positioning part 322, and a clamping part 323. The fixing part 321 includes a first plate 3211 parallel to the support frame 310 and a second plate 3212 perpendicularly mounted to the first plate 3211. The first plate 3211 is located on the side of the support frame 310 facing the second plate 120 and is mounted on the support frame 310 with screws. The positioning part 322 is mounted on the side of the first plate 3211 away from the second plate 3212 with screws and extends in a direction away from the second plate 3212. The clamping part 323 is located on one side of the positioning part 322. A first rotating shaft 328 is provided between the clamping part 323 and the positioning part 322, allowing rotation via the first rotating shaft 328. A first elastic element 324 is sleeved on the first rotating shaft 328. The two ends of the first elastic element 324 extend away from the fixed part 321 and abut against the positioning part 322 and the clamping part 323 respectively, so that the ends of the positioning part 322 and the clamping part 323 away from the fixed part 321 tend to move away from each other. Due to the setting of the first rotating shaft 328, the ends of the positioning part 322 and the clamping part 323 near the fixed part 321 move closer to each other. Since the positioning part 322 is fixedly installed on the fixed part 321, and the fixed part 321 is fixed on the support frame 310, the first elastic element 324 drives the clamping part 323 to rotate, so that the end of the clamping part 323 near the fixed part 321 rotates toward the fixed part 321 and cooperates with the second plate 3212 to clamp the PCB board 10.

[0071] The clamping structure 320 also includes a limiting part 325, which is located at the end of the positioning part 322 away from the fixing part 321 and is rotatably connected to the end of the clamping part 323 away from the fixing part 321 via a second rotating shaft 329. A hook part 327 is provided on the side of the limiting part 325 away from the clamping part 323. The hook part 327 is detachably connected to the positioning part 322, allowing it to have a first state and a second state. In the first state, the hook part 327 engages with the positioning part 322. Because the hook part 327 and the positioning part 322 are relatively fixed, the clamping part 323 and the hook part 327 are also relatively fixed. Even if the first elastic member 324 drives the end of the clamping part 323 away from the fixing part 321 away from the positioning part 321... 22. The clamping part 323 cannot move either. Therefore, there is a certain gap between the end of the clamping part 323 near the fixing part 321 and the second plate 3212, so that the PCB board 10 can be inserted between the second plate 3212 and the clamping part 323. In the second state, after the hook part 327 disengages from the positioning part 322, the positioning part 322 releases the restriction on the hook part 327. Under the drive of the first elastic member 324, the end of the clamping part 323 away from the fixing part 321 rotates in the direction away from the positioning part 322, and the end near the fixing part 321 rotates towards the fixing part 321, and cooperates with the second plate 3212 to clamp the PCB board 10, preventing the PCB board 10 in the first positioning groove 211 from swinging.

[0072] In an embodiment of the present invention, the clamping structure 320 further includes a second elastic member 326. The second elastic member 326 is disposed on the second rotating shaft 329. The two ends of the second elastic member 326 abut against the side of the limiting portion 325 facing the clamping portion 323 and the side of the clamping portion 323 facing the limiting portion 325, respectively, so that the clamping structure 320 has a tendency to maintain the first state.

[0073] Specifically, referring to Figure 6, a second elastic element 326 is provided on the second rotating shaft 329. The second elastic element 326 can be a leaf spring, with both ends extending away from the fixing part 321. The two ends of the second elastic element 326 abut against the sides of the limiting part 325 and the clamping part 323 facing each other. When the hook part 327 is engaged with the positioning part 322, the second elastic element 326 drives the limiting part 325 to rotate toward the positioning part 322 and also drives the clamping part 323 to rotate away from the positioning part 322, further preventing the hook part 327 from disengaging from the positioning part 322. When it is necessary to clamp the PCB board 10, it is only necessary to push the clamping part 323 and the limiting part 325 to move toward the positioning part 322, so that the hook part 327 can be disengaged from the positioning part 322, and under the drive of the first elastic element 324, the clamping part 323 can be clamped with the fixing part 321.

[0074] In an embodiment of this utility model, the support frame 310 is provided with a plurality of mounting holes 311 spaced apart along the first direction, and each clamping structure 320 is provided corresponding to each mounting hole 311. The fixing part 321 is provided on the side of the support frame 310 away from the first plate 110, the positioning part 322 is provided on the side of the support frame 310 close to the first plate 110, and the clamping part 323 extends out of the mounting hole 311 at one end close to the fixing part 321.

[0075] Specifically, referring to Figure 3, multiple mounting holes 311 are spaced horizontally on the support frame 310. The mounting holes 311 penetrate the support frame 310. The clamping structure 320 is located at the corresponding mounting hole 311. The fixing part 321 is installed on the side of the support frame 310 facing the second plate 120. Part of the first plate 3211 is fixed to the support frame 310 with screws, and the other part is at the mounting hole 311 and is connected to the positioning part 322. The clamping part 323 extends out of the mounting hole 311 near the fixing part 321 and cooperates with the fixing part 321 to clamp the PCB board 10. The other end extends away from the fixing part 321 at the mounting hole 311. That is, on the side of the support frame 310 away from the fixing part 321, the clamping part 323 and the fixing part 321 are clamped by controlling the hook part 327, which does not affect the clamping and storage of the PCB board 10 and avoids the difficulty of controlling the same side, thus affecting the operation.

[0076] 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.
