Description

Technical Field

[0001] This utility model relates to the technical field of patch positioning device, and more particularly to a patch positioning device. Background Technology

[0002] Surface mount technology (SMT) is an assembly technique that directly mounts electronic components onto the surface of a printed circuit board (PCB). Due to its high integration, small size, and light weight, SMT has rapidly become the mainstream assembly technology in electronic product manufacturing. However, in actual production processes, especially in small-batch production, prototyping, or repair scenarios, relying entirely on automated equipment for SMT positioning may not be economical or practical. Manual SMT positioning devices are tools that allow for the placement and positioning of electronic components manually. They typically consist of a base and an adjustable positioning platform, with the operator using auxiliary tools (such as tweezers or a pick-up pen) to pick up the SMT components for placement.

[0003] Chinese patent publication number CN213403685U discloses a positioning device for SMT component placement, including a positioning stage, a movable plate, and a connecting frame. Slide rails are formed on both sides of the center of the positioning stage. Fixed plates are provided on both sides of the lower end of the positioning stage. The movable plate is positioned between the fixed plates, and a movable plate is positioned on one side of the movable plate. A threaded hole is formed in the center of the movable plate, and a threaded hole is formed in the center of the movable plate. The connecting frame is located in the center of the side wall of the fixed plate away from the movable plate. The advantages are: This utility model, by setting up a positioning stage, slide rails, fixed plates, movable plate one, movable plate two, connecting frame, stepper motor one, threaded hole one, threaded hole two, connecting plate one, positioning clamp one, connecting plate two, and positioning clamp two, allows the PCB board to be placed to be conveniently positioned and fixed in the center of the upper part of the positioning stage by the positioning clamp one and positioning clamp two, facilitating component placement. It is very practical.

[0004] Existing surface mount positioning devices have drawbacks, such as being able to clamp and position only a single circuit board, and the circuit board not being subjected to vertical pressure, which can easily lead to unevenness (e.g., the two ends are not on the same horizontal plane), thus affecting the surface mount operation. To overcome these disadvantages, this utility model provides a surface mount positioning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a patch positioning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a patch positioning device, including a base, a worktable fixedly connected to the top of the base, both the base and the worktable having hollow interiors, a plurality of sliding grooves equally spaced on the top of the worktable, sliders symmetrically slidably connected within the sliding grooves, guide rods fixedly connected within the sliding grooves, the sliders slidably connected to the guide rods, a clamping block fixedly connected to the top of the slider, an adjusting component for adjusting the distance between the clamping blocks on both sides being provided in the worktable at a position corresponding to the sliding groove, a pressing component being provided on the clamping block, and an illumination component being provided on the base.

[0007] Furthermore, the adjustment assembly includes a screw rotatably connected to the worktable, a movable block threadedly connected to the screw, a first connecting seat fixed to the bottom of the slider, second connecting seats symmetrically fixed to both ends of the movable block, a connecting rod hinged inside the second connecting seat, the end of the connecting rod hinged to the corresponding first connecting seat, and a drive assembly for driving the screw to rotate is provided inside the base.

[0008] Furthermore, the drive assembly includes a rotating shaft rotatably connected to the base and a drive motor fixed to the base. The output end of the drive motor is fixedly connected to the rotating shaft. One end of each screw extends into the base and is fixedly connected to a driven bevel gear. Each rotating shaft is fixedly connected to a driving bevel gear at a position corresponding to the driven bevel gear. The driving bevel gear meshes with the corresponding driven bevel gear.

[0009] Furthermore, the pressing assembly includes a support plate fixed to the outside of the clamping block and a connecting frame located above the clamping block. The connecting frame has an L-shaped structure. A telescopic rod is fixed between the connecting frame and the support plate. A return spring is sleeved on the outside of the telescopic rod. The two ends of the return spring are fixed to the support plate and the connecting frame, respectively. One end of the connecting frame extends to the inside of the clamping block and is fixed to a pressing head. The pressing head has a ball bearing at its bottom.

[0010] Furthermore, the lighting assembly includes a support frame, which is a U-shaped structure. Guide rails are fixedly connected to the top sides of both ends of the base. Both ends of the support frame are slidably connected to the guide rails. Limiting rods are fixedly connected inside the guide rails. The support frame is slidably connected to the limiting rods. A lamp is fixedly connected to the top of the support frame at the position corresponding to the slide groove.

[0011] Furthermore, a rubber pad is fixed to the inner side of the clamping block.

[0012] The beneficial effects of this utility model are:

[0013] When in use, this patch positioning device has the following advantages:

[0014] 1. In this solution, a base, worktable, slide, guide rod, slider, clamping block, first connecting seat, screw, moving block, second connecting seat, connecting rod, driven bevel gear, rotating shaft, driving bevel gear, support frame, illumination lamp, and guide rail are provided. Multiple circuit boards of the same size to be mounted are placed at the corresponding positions of each clamping block. The drive motor drives the rotating shaft and driving bevel gear to rotate, and the driven bevel gear meshing with it rotates synchronously. This causes several sets of screws to rotate synchronously, which in turn drives the moving block to move downward. With the combined action of the second connecting seat, connecting rod, and first connecting seat, the slider and clamping block on both sides move towards each other. The clamping blocks on both sides are used to clamp and position the circuit boards. Multiple sets of circuit boards can be clamped at the same time, eliminating the need to clamp them one by one, thus improving clamping efficiency. The support frame can be moved horizontally and slides along the guide rail, making it easy to adjust the illumination position of the illumination lamp, which provides auxiliary illumination during the mounting process.

[0015] 2. In this solution, a support plate, connecting frame, telescopic rod, return spring, pressure head, and ball bearings are provided. During the clamping process, the ball bearings of the pressure head at the bottom of the connecting frame on the clamping block roll against the upper side of the circuit board. The telescopic rod and return spring extend accordingly, pressing the circuit board vertically onto the worktable, improving the stability of clamping and positioning, and avoiding the impact on operation due to unevenness of the circuit board (such as tilting at both ends or not being on the same horizontal plane) during chip placement.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0025] Example 1

[0026] A patch positioning device includes a base 1, a worktable 2 fixedly connected to the top of the base 1, both the base 1 and the worktable 2 having hollow interiors, a plurality of grooves 3 equally spaced on the top of the worktable 2, sliders 5 symmetrically slidably connected within the grooves 3, guide rods 4 fixedly connected within the grooves 3, sliders 5 slidably connected to guide rods 4, clamping blocks 6 fixedly connected to the top of sliders 5, rubber pads fixedly connected to the inner side of clamping blocks 6, adjusting components for adjusting the distance between the clamping blocks 6 on both sides are provided in the worktable 2 at positions corresponding to the grooves 3, clamping blocks 6 are provided with pressing components, and lighting components are provided on the base 1.

[0027] In this embodiment, as Figure 1-4 As shown, multiple circuit boards of the same size to be mounted are placed at the corresponding positions of each set of clamping blocks 6. The clamping blocks 6 are moved towards each other by the adjusting component. The circuit boards are clamped and positioned by the clamping blocks 6 on both sides. During the clamping process, the pressing component on the clamping block 6 presses the circuit board vertically onto the worktable 2 surface, improving the stability of the clamping and positioning and avoiding the impact of uneven circuit boards on the operation during mounting. The lighting component provides auxiliary lighting during the mounting process.

[0028] Example 2

[0029] The adjustment assembly includes a screw 8 rotatably connected to the workbench 2, a moving block 9 threadedly connected to the screw 8, a first connecting seat 7 fixedly connected to the bottom of the slider 5, and second connecting seats 10 symmetrically fixedly connected to both ends of the moving block 9. A connecting rod 11 is hinged inside the second connecting seat 10, and the end of the connecting rod 11 is hinged to the corresponding first connecting seat 7. A drive assembly for driving the screw 8 to rotate is provided in the base 1. The drive assembly includes a rotating shaft 13 rotatably connected to the base 1 and a drive motor 15 fixedly connected to the base 1. The output end of the drive motor 15 is fixedly connected to the rotating shaft 13, and the drive motor 15 is electrically connected to an external power supply. One end of each screw 8 extends into the base 1 and is fixedly connected to a driven bevel gear 12. A driving bevel gear 14 is fixedly connected to the rotating shaft 13 at the position corresponding to the driven bevel gear 12. The driving bevel gear 14 meshes with the corresponding driven bevel gear 12.

[0030] In this embodiment, as Figure 2 , 3 As shown in Figure 4, the drive motor 15 is started, which drives the rotating shaft 13 and the active bevel gear 14 to rotate. The driven bevel gear 12, which meshes with it, rotates synchronously. Then, several sets of screws 8 rotate synchronously, which in turn drives the moving block 9 to move downward. With the combined action of the second connecting seat 10, the connecting rod 11, and the first connecting seat 7, the sliders 5 and clamping blocks 6 on both sides move towards each other. The clamping blocks 6 on both sides are used to clamp and position the circuit board. At the same time, multiple sets of circuit boards are clamped, eliminating the need to clamp them one by one, thus improving clamping efficiency.

[0031] Example 3

[0032] The pressing assembly includes a support plate 16 fixed to the outside of the clamping block 6 and a connecting frame 17 located above the clamping block 6. The connecting frame 17 has an L-shaped structure. A telescopic rod 18 is fixed between the connecting frame 17 and the support plate 16. A return spring 19 is sleeved on the outside of the telescopic rod 18. The two ends of the return spring 19 are fixed to the support plate 16 and the connecting frame 17 respectively. One end of the connecting frame 17 extends to the inside of the clamping block 6 and is fixed to a pressing head 20. The pressing head 20 is provided with a ball bearing at its bottom.

[0033] In this embodiment, as Figure 2 As shown, during the clamping process, the ball bearings of the bottom pressing head 20 of the connecting bracket 17 on the clamping block 6 roll against the upper side of the circuit board during the clamping process, and the telescopic rod 18 and the return spring 19 extend accordingly, pressing the circuit board onto the worktable 2 surface in the vertical direction, improving the stability of clamping and positioning, and avoiding the impact of uneven circuit board on operation during chip placement.

[0034] Example 4

[0035] The lighting assembly includes a support frame 21, which has a U-shaped structure. Guide rails 23 are fixedly connected to the top sides of both ends of the base 1. Both ends of the support frame 21 are slidably connected to the guide rails 23. Limiting rods are fixedly connected inside the guide rails 23. The support frame 21 is slidably connected to the limiting rods. A lamp 22 is fixedly connected to the top of the support frame 21 at the position corresponding to the slide groove 3. The lamp 22 is electrically connected to an external power supply.

[0036] In this embodiment, as Figure 1 As shown, the support frame 21 can be moved horizontally and slides along the guide rail 23 to facilitate adjustment of the illumination position of the lamp 22, providing auxiliary illumination during the patch application process.

[0037] The working principle of this utility model is as follows: Multiple circuit boards of the same size to be mounted are placed at the corresponding positions of the clamping blocks 6. The drive motor 15 is started, which drives the rotating shaft 13 and the driving bevel gear 14 to rotate. The driven bevel gear 12 meshing with it rotates synchronously, and then several sets of screws 8 rotate synchronously. This drives the moving block 9 to move downward. With the combined action of the second connecting seat 10, the connecting rod 11, and the first connecting seat 7, the sliders 5 and clamping blocks 6 on both sides move towards each other. The clamping blocks 6 on both sides are used to clamp and position the circuit boards. Multiple circuit boards can be clamped at once, eliminating the need to clamp them one by one, thus improving clamping efficiency. At the same time, the ball bearings of the bottom pressing head 20 of the connecting bracket 17 on the clamping block 6 roll against the upper side of the circuit board during clamping, and the telescopic rod 18 and the return spring 19 extend accordingly, pressing the circuit board vertically onto the worktable 2 surface, improving the stability of clamping and positioning, and avoiding the impact of uneven circuit boards on operation during placement. The support bracket 21 can be moved horizontally and slides along the guide rail 23, making it easy to adjust the lighting position of the illumination lamp 22, providing auxiliary lighting during the placement process.
