Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing equipment, and more specifically to a circuit board integrated stacking equipment. Background Technology

[0002] A single circuit board can only perform limited circuit functions. During production, multiple circuit boards are often stacked and electrically connected to meet more complex circuit function requirements. Existing circuit board stacking equipment stacks circuit boards sequentially to complete the stacking installation. When the number of stacked circuit boards is large, such as producing and installing a five-layer stacked circuit board, four stacking installations are required to complete the process. This results in numerous stacking operations, long installation time, and low production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of long installation time and low efficiency of existing circuit board stacking and installation, and to provide a circuit board integrated stacking device that can stack the required circuit boards in one go.

[0004] To achieve the above objectives, this utility model provides a circuit board integration stacking device for stacking several circuit boards of the same specifications. The stacking device includes:

[0005] A plurality of clamps, wherein when a circuit board is clamped in two or more of the clamps, the normal to the surface of the clamped circuit board extends along a first direction and coincides;

[0006] A plurality of mounting brackets, each of which is equipped with a clamp, and the plurality of mounting brackets are equidistantly distributed along the first direction;

[0007] An adjustment device is provided for adjusting the spacing between the mounting frames along the first direction, wherein the mounting frames remain equidistantly distributed during the adjustment process.

[0008] The frame, the adjustment device is mounted on the frame, and the mounting bracket is slidably mounted on the frame.

[0009] In some embodiments, the adjusting device includes a driving mechanism and a symmetrical scissor-type telescopic frame. The driving mechanism is used to drive the scissor-type telescopic frame to extend and retract along the first direction, and a plurality of mounting frames are equally spaced and installed on the scissor-type telescopic frame along the first direction.

[0010] In some embodiments, the drive mechanism includes a drive source and two moving blocks. The drive source is used to drive the two moving blocks to move closer to or further away from each other along a direction perpendicular to the first direction. The two moving blocks are hinged to the power input end of the scissor telescopic frame. The scissor telescopic frame is driven to extend and retract along the first direction by the movement of the two moving blocks along the direction perpendicular to the first direction.

[0011] In some embodiments, the drive source includes a stepper motor and a drive screw, the drive screw being connected to the power output end of the stepper motor, and at least one of the moving blocks being threadedly connected to the drive screw.

[0012] In some embodiments, the drive screw is threadedly connected to both of the moving blocks and the threads are in opposite directions. When the drive screw rotates and drives the two moving blocks to move closer to or further away from each other, the moving speeds of the two moving blocks are equal.

[0013] In some embodiments, the scissor telescopic frame includes several sets of scissor linkages distributed along the first direction. Each scissor linkage includes two rods of equal length, with the middle portions of the two rods hinged together by a central hinge axis. The rods of adjacent scissor linkages are hinged together by end hinge axes. The axes of the central hinge axis and the end hinge axes are parallel and perpendicular to the first direction. The end hinge axes are slidably connected to one of the mounting frames.

[0014] In some embodiments, the two end hinge shafts located on the same plane perpendicular to the first direction are slidably connected to the same mounting bracket.

[0015] In some embodiments, a guide groove is provided on the frame, and the intermediate hinge shaft is slidably connected to the guide groove.

[0016] In some embodiments, a rotating frame is rotatably mounted on the mounting frame, the clamp is fixedly mounted on the rotating frame, and a rotary motor is fixedly mounted on the mounting frame. The rotary motor is used to drive the rotating frame to rotate so that the clamp switches between a working state and an idle state. The rotation axis of the rotating frame is perpendicular to the first direction.

[0017] When the fixture is in working condition and holding the circuit board, the normal line of the circuit board surface held by the fixture extends along the first direction;

[0018] When the fixture is in an idle state and holds the circuit board, the normal line of the circuit board held by the fixture extends perpendicular to the first direction.

[0019] In some embodiments, the adjustment range of the adjustment device must at least satisfy the following condition: when the clamp is switched to an idle state, the spacing between adjacent mounting brackets along the first direction is greater than the length of the clamp along the first direction.

[0020] The circuit board integration and stacking device using the above-mentioned technical solution of this utility model has the following effects:

[0021] Based on the production requirements for the number of circuit board stacking layers, the circuit boards are clamped on a continuous number of fixtures with the same number of stacking layers. The mounting brackets are moved by an adjustment device to reduce the spacing between the mounting brackets, thereby reducing the spacing between the fixtures and the circuit boards. Since the mounting brackets maintain an equidistant distribution during the movement, all circuit boards can be stacked and connected simultaneously, eliminating the need for multiple stacking installations due to the large number of circuit board stacking layers. This is convenient, fast, and improves installation efficiency.

[0039] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0040] This utility model provides a circuit board integration stacking device for stacking several circuit boards 4 of the same specifications. The circuit board 4 is generally rectangular, with positioning holes 20 at the top corners or edges. Connectors 19 can pass through the positioning holes 20. When stacking the circuit boards 4, the connectors 19 on adjacent circuit boards 4 are plugged in to complete the stacking. The stacked circuit boards 4 are shown in the attached figure. Figure 1 and attached Figure 2 As shown, attached Figure 1 and attached Figure 2 The stacked circuit boards 4 in the middle are all five layers, and each circuit board 4 has six positioning holes 20.

[0041] The stacking equipment includes several clamps 3, several mounting brackets 7, adjusting devices 8, and a frame 1. (See attached diagram.) Figure 3 As shown, each clamp 3 is used to hold a circuit board 4. When two or more clamps 3 hold circuit boards 4, the normals of the clamped circuit boards 4 extend along the first direction and coincide. Each mounting bracket 7 is equipped with a clamp 3, and several mounting brackets 7 are equidistantly distributed along the first direction, so that when the clamps 3 hold circuit boards 4, the circuit boards 4 are also equidistantly distributed along the first direction. The adjusting device 8 is used to adjust the spacing between the mounting brackets 7 along the first direction. During the adjustment of the mounting brackets 7, several mounting brackets 7 still maintain an equidistant distribution, and the clamps 3 on the mounting brackets 7 and the circuit boards 4 clamped on the clamps 3 also move with the mounting brackets 7. The frame 1 provides a mounting platform, the adjusting device 8 is mounted on the frame 1, and the mounting brackets 7 are slidably mounted on the frame 1 to improve the stability of the mounting brackets 7 during movement.

[0042] In this embodiment, combined with the appendix Figure 3 and attached Figure 4 As shown, five mounting brackets 7 and five clamps 3 are provided for stacking five-layer circuit boards 4. During use, a robotic arm (not shown) simultaneously and separately places the five circuit boards 4, with connectors 19 inserted, onto the five clamps 3, and then the clamps 3 clamp all five circuit boards 4. (See attached diagram.) Figure 5 The adjusting device 8 adjusts the mounting brackets 7 and reduces the spacing between them, thereby reducing the spacing between the clamps 3 on the mounting brackets 7 and the spacing between the circuit boards 4. During this reduction, the connectors 19 between adjacent circuit boards 4 interlock until the connectors 19 are fully engaged, at which point all five circuit boards 4 are stacked sequentially. Then, all clamps 3 release the circuit boards 4, and a robotic arm (not shown) removes the stacked circuit boards 4 from the equipment. This stacking equipment requires only one installation process to complete the stacking of five layers of circuit boards 4, reducing the number of stacking operations, making it convenient, fast, and improving production efficiency.

[0043] For the production of circuit boards 4 with more layers, the number of mounting brackets 7 and clamps 3 can be adjusted appropriately. For the production of circuit boards 4 with fewer layers, i.e., when the number of stacked circuit boards 4 is less than the number of mounting brackets 7 and clamps 3, this method can be directly applied. Specifically, when there are five mounting brackets 7 and five clamps 3, it can be directly used for stacking circuit boards 4 with four or three layers. For example, when the number of stacked circuit boards 4 is four layers, the circuit boards 4 can be clamped on any four adjacent clamps 3, and the spacing of the mounting brackets 7 can be adjusted using the adjusting device 8. Similarly, when the number of stacked circuit boards 4 is three layers, the circuit boards 4 can be clamped on any three adjacent clamps 3, and the spacing of the mounting brackets 7 can be adjusted using the adjusting device 8.

[0044] It should be noted that when the circuit board 4 is stacked in two layers, the circuit board 4 can be clamped on any two adjacent clamps 3 from the five clamps 3, and the spacing of the mounting brackets 7 can be adjusted by the adjusting device 8. The installation efficiency of the two-layer circuit board 4 stack is basically the same as that of the existing installation method.

[0045] Therefore, in this embodiment, the stacking device is provided with five mounting brackets 7 and five clamps 3, which can be used to stack two to five layers of circuit boards 4. The more layers of circuit boards 4 are stacked, the more significant the improvement in installation efficiency.

[0046] In some embodiments, in conjunction with the appendix Figure 6 As shown, the adjustment device 8 includes a drive mechanism 9 and a symmetrical scissor-type telescopic frame 10. The drive mechanism 9 is used to drive the scissor-type telescopic frame 10 to extend and retract along a first direction, and a plurality of mounting frames 7 are equally distributed and installed on the scissor-type telescopic frame 10 along the first direction. By driving the symmetrical scissor-type telescopic frame 10 to extend and retract along the first direction through the drive mechanism 9, the plurality of mounting frames 7 installed on the scissor-type telescopic frame 10 are moved along the first direction to achieve spacing adjustment. Since the scissor-type telescopic frame 10 is symmetrical, it is ensured that the mounting frames 7 remain equally distributed during the adjustment process.

[0047] In some embodiments, in conjunction with the appendix Figure 7The drive mechanism 9 includes a drive source 11 and two moving blocks 12. The drive source 11 drives the two moving blocks 12 to move closer to or further apart along a first direction perpendicular to it. The two moving blocks 12 are hinged to the power input end of the scissor-type telescopic frame 10. The movement of the two moving blocks 12 along the first direction drives the scissor-type telescopic frame 10 to extend or retract along the first direction. During use, when the drive source 11 drives the two moving blocks 12 closer to each other, the scissor-type telescopic frame 10 extends along the first direction, adjusting and increasing the spacing between the mounting brackets 7. When the drive source 11 drives the two moving blocks 12 further apart, the scissor-type telescopic frame 10 retracts along the first direction, adjusting and decreasing the spacing between the mounting brackets 7. By driving and controlling the extension and retraction of the scissor-type telescopic frame 10 through the drive source 11, the control accuracy is improved.

[0048] In some embodiments, the drive source 11 includes a stepper motor 13 and a drive screw 14. The drive screw 14 is connected to the power output end of the stepper motor 13, and at least one moving block 12 is threadedly connected to the drive screw 14. Specifically, the extension and retraction of the scissor-type telescopic frame 10 is based on the change in the distance between two moving blocks 12, and the change in the distance between the two moving blocks 12 is essentially due to the different speeds of the two moving blocks 12. When one of the moving blocks 12 is connected to the drive screw 14, the drive screw 14 drives the moving block 12 to move, while the other moving block 12 remains stationary, thereby achieving a different speed between the two moving blocks 12. (See attached diagram.) Figure 8 As shown, for ease of distinction, the stationary moving block is referred to as fixed block 12a, and the moving block connected to the drive screw 14 is referred to as movable block 12b. (See attached diagram.) Figure 8 In the diagram, the dashed line represents the state of the movable block 12b and the scissor telescopic frame 10 when retracted, and the solid line represents the state of the movable block 12b and the scissor telescopic frame 10 when extended.

[0049] In some embodiments, the drive screw 14 is threadedly connected to both moving blocks 12 with opposite thread directions. When the drive screw 14 rotates and drives the two moving blocks 12 to move closer to or further apart, the moving speeds of the two moving blocks 12 are equal. This design ensures that during the movement of the two moving blocks 12, the scissor-type telescopic frame 10 only extends and retracts along the first direction, without any offset in the direction perpendicular to the first direction. (See attached diagram.) Figure 9 The dashed lines represent the state of the moving block 12 and the scissor telescopic frame 10 when they are retracted, and the solid lines represent the state of the moving block 12 and the scissor telescopic frame 10 when they are extended.

[0050] In some embodiments, in conjunction with the appendix Figure 10The scissor-type telescopic frame 10 includes several sets of scissor-type linkage groups 15 distributed along a first direction. Each scissor-type linkage group 15 includes two rods 16 of equal length, which are hinged at the middle by a central hinge shaft 17. The rods 16 of adjacent scissor-type linkage groups 15 are hinged to each other by end hinge shafts 18. Since the scissor-type telescopic frame 10 is symmetrical, the rods 16 of each scissor-type linkage group 15 are also of equal length. The axes of the central hinge shaft 17 and the end hinge shafts 18 are parallel and perpendicular to the first direction. The end hinge shafts 18 are slidably engaged with one of the mounting brackets 7. In this embodiment, four sets of scissor-type linkage groups 15 are provided, and five sets of end hinge shafts 18 are provided. One set of end hinge shafts 18 is used to connect the edge scissor-type linkage groups 15 to the drive mechanism 9, so that the scissor-type telescopic frame 10 can receive the driving force of the drive mechanism 9. In addition, the mounting bracket 7 is slidably connected to the end hinge shaft 18 so that the spacing between the mounting brackets 7 is equal to the unfolded length of the scissor linkage 15 in the first direction, which makes it easier to calculate and determine the spacing between the mounting brackets 7.

[0051] In some embodiments, in conjunction with the appendix Figure 11 and attached Figure 12 Two end hinge shafts 18, which are located on the same vertical first direction plane, are slidably connected to the same mounting frame 7 to improve the connection strength between the mounting frame 7 and the scissor telescopic frame 10.

[0052] In some embodiments, in conjunction with the appendix Figure 5 and attached Figure 6 The frame 1 has a guide groove 2, and the intermediate hinge shaft 17 slides in connection with the guide groove 2. The guide groove 2 is designed to improve the stability of the scissor-type telescopic frame 10 during its extension and retraction. It should be noted that both the intermediate hinge shaft 17 and the end hinge shaft 18 are hinged to the rod 16. During the extension and retraction of the scissor-type telescopic frame 10, the intermediate hinge shaft 17 and the end hinge shaft 18 do not necessarily need to rotate. Therefore, the sliding connection between the intermediate hinge shaft 17 and the guide groove 2, and the sliding connection between the end hinge shaft 18 and the mounting frame 7, do not affect the extension and retraction function of the scissor-type telescopic frame 10.

[0053] In some embodiments, in conjunction with the appendix Figure 13 and attached Figure 14A rotating frame 5 is rotatably mounted on the mounting bracket 7, and a clamp 3 is fixedly mounted on the rotating frame 5. A rotary motor 6 is fixedly mounted on the mounting bracket 7, which drives the rotating frame 5 to rotate, allowing the clamp 3 to switch between a working state and an idle state. The rotation axis of the rotating frame 5 is perpendicular to a first direction. When the clamp 3 is in the working state and holds the circuit board 4, the normal line of the circuit board 4 held on the clamp 3 extends along the first direction. When the clamp 3 is in the idle state and holds the circuit board 4, the normal line of the circuit board 4 held on the clamp 3 extends perpendicular to the first direction. Specifically, during the process of switching the clamp 3 from the working state to the idle state, the rotating frame 5 rotates 90 degrees, making it convenient to place the circuit board 4 on the clamp 3 in the idle state.

[0054] In some embodiments, the adjustment range of the adjusting device 8 must at least satisfy the following: when the clamp 3 is switched to an idle state, the distance between adjacent mounting brackets 7 along the first direction is greater than the length of the clamp 3 along the first direction, so as to avoid interference between adjacent mounting brackets 7 and clamp 3. In this embodiment, the adjustment range of the adjusting device 8 satisfies the following: when the adjusting device 8 adjusts the distance between the mounting brackets 7 to the maximum value, the clamp 3 is switched to an idle state, at which time the distance between adjacent mounting brackets 7 along the first direction is greater than the length of the clamp 3 along the first direction.

[0055] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0056] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0057] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
