Description

Technical Field

[0001] This utility model relates to a processing bracket, and more particularly to a circuit board processing bracket. Background Technology

[0002] Circuit board processing supports are used to support and fix circuit boards during the processing. Common types include frame-type and clamp-type supports. Existing circuit board processing supports have the following defects:

[0003] 1. Insufficient positioning stability: The fixture design does not take into account the high-frequency vibration environment, which can easily cause the circuit board to shift during processing. Insufficient clamping force can also easily cause shifting and loosening. Furthermore, it lacks multi-dimensional positioning and clamping, resulting in insufficient stability.

[0004] 2. Insufficient size adaptability: Although the frame-shaped bracket has good stability, the fixed limiting structure usually only supports a single specification of circuit board.

[0005] A circuit board processing bracket, disclosed in publication number CN221688923U, comprises a base plate with symmetrically arranged support shafts on both sides of its upper end. Each support shaft has a support rod rotatably connected to it, and each support rod has a fixed positioning shaft. Sliding rods are also symmetrically arranged on both sides of the base plate, each sliding rod having a slider slidably connected to it. Each slider is connected to a corresponding positioning shaft via a corresponding positioning rod, and each slider has a bolt threadedly connected to it. A limit shaft is also provided above the base plate, passing through two support rods. Both ends of the limit shaft have nuts threadedly connected to it. This device allows adjustment of the circuit board's fixed height and tilt angle when fixing it. While this design combines the functions of a bracket and a clamp, the circuit board's clamping and positioning rely solely on springs, resulting in insufficient positioning stability. The uneven mechanical clamping force of the springs also contributes to the tendency for misalignment. Utility Model Content

[0008] The transmission assembly includes a sliding unit and a hydraulic cylinder, and also includes a non-standard transmission component that is hinged to the sliding unit and the hydraulic cylinder to enable their movement and cooperation. The non-standard transmission component includes a first non-standard transmission component and a second non-standard transmission component.

[0017] Furthermore, the positioning fixture includes a fixing block, one side of which is connected to the end face of the first wedge-shaped positioning slider and / or the second wedge-shaped positioning slider, and the first clamping block and the second clamping block are located on the free end face of the fixing block.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-6 As shown in the figure, this embodiment of the circuit board processing bracket includes a frame 1 with an internally formed open cavity 2. A transmission component is disposed within the open cavity 2 and extends out through openings formed at both ends of the open cavity 2, that is, as shown in the figure. Figure 1 As shown, the open cavity 2 has openings at both ends, which are used to form a completely rigid connection for the transmission components.

[0031] like Figure 1 As shown, a first wedge-shaped groove 3 and a second wedge-shaped groove 6 are formed on the frame 1, which are symmetrical to each other. A processing recess 5 is spaced between the first wedge-shaped groove 3 and the second wedge-shaped groove 6. The processing recess 5 is implemented to increase the positioning depth. A first wedge-shaped positioning slider 4 and a second wedge-shaped positioning slider 7 are respectively matched in the first wedge-shaped groove 3 and the second wedge-shaped groove 6 and are slidably connected by a transmission component. Positioning clamps 24 are provided on the opposite surfaces of the first wedge-shaped positioning slider 4 and the second wedge-shaped positioning slider 7. The two positioning clamps 24 work together to clamp the circuit board. The setting of the positioning clamps 24 makes the clamping more accurate and stable, and effectively copes with the high-frequency vibration environment. In addition, when there is no high-frequency vibration in the processing environment, this embodiment can also use the first wedge-shaped positioning slider 4 and the second wedge-shaped positioning slider 7 to move closer / away from each other through the transmission component to quickly position the circuit board and prevent loosening, thereby improving the processing efficiency. Moreover, the mutual approach / away of the first wedge-shaped positioning slider 4 and the second wedge-shaped positioning slider 7 can adapt to circuit boards of various sizes in this embodiment, with extremely strong compatibility.

[0032] In this embodiment, the positioning fixture 24 includes a first clamping block 26 and a second clamping block 27 that cooperate with each other. In this embodiment, the tilt angle of the positioning fixture 24 positioning circuit board can also be changed by adjusting the connection and installation angle of the positioning fixture 24 during production.

[0033] Preferably, the positioning clamp 24 includes a fixing block 25, such as Figure 4 As shown, the surface of the fixing block 25 is flat. When this embodiment is used for quick clamping and no tilt angle is required during production, the fixing block 25 can also serve as a support for the circuit board. That is, not only can the recessed area 5 be used to place the circuit board, but the fixing blocks 25 on both sides can also be used together to place the circuit board for processing. One side of the fixing block 25 is connected to the end face of the first wedge-shaped positioning slider 4 and / or the second wedge-shaped positioning slider 7. The first clamping block 26 and the second clamping block 27 are located on the free end face of the fixing block 25, as shown. Figure 4 As shown, the gap between the fixing block 25 and the first clamping block 26 and the second clamping block 27 also forms an inward clearance.

[0034] Preferably, the first clamping block 26 is fastened to the fixed block 25 by bolts. In this embodiment, the first clamping block 26 is a fastening structure, that is, it does not move during the clamping and adjustment process. As mentioned above, a fitting gap is formed between the first clamping block 26 and the second clamping block 27 for adjustment to clamp circuit boards of different thicknesses. It can be understood that the clamping combination of the first wedge-shaped positioning slider 4 and the second wedge-shaped positioning slider 7, combined with the clamping combination of the first clamping block 26 and the second clamping block 27, provides multi-dimensional positioning and clamping of the circuit board, further improving the clamping stability of this embodiment.

[0035] like Figure 4-5 As shown, the second clamping block 27 has a through threaded channel inside, which is implemented by mounting a screw 28 inside. The free end of the screw 28 is connected to an abutment plate 29, which is parallel to the clamping plate surface of the first clamping block 26. The abutment plate 29 is made of rubber. In this embodiment, the second clamping block 27 is a movable clamping part. Specifically, the abutment plate 29 moves closer to the clamping plate of the first clamping block 26 when the screw 28 is inserted. As the screw 28 rotates to insert, the abutment plate 29 moves closer to the clamping plate of the first clamping block 26. The connecting plate 29 rotates synchronously with the screw 28. Therefore, the gap formed by the fixing block 25 located between the first clamping block 26 and the second clamping block 27 provides clearance for the rotation of the connecting plate 29, thus not affecting the clamping action of the first clamping block 26. At the same time, after the connecting plate 29 initially engages with the clamping plate surface of the first clamping block 26 to form a clamping force on the circuit board, the elasticity of the rubber material of the connecting plate 29 can further tighten the screw 28 to strengthen the clamping of the circuit board and improve stability.

[0036] Meanwhile, to facilitate rapid disengagement of the circuit board during disassembly, the clamping plate surface of the second clamping block 27 is provided with multiple spring holes 30 extending in the same direction as the threaded channels. Each spring hole 30 is fitted with a spring 31 fixed at one end, and the other end of the spring 31 is connected to the inner side of the abutment plate 29. Under normal conditions, the abutment plate 29 and the clamping plate surface of the second clamping block 27 abut against each other, and the spring 31 does not apply elastic force. When the abutment plate 29 is pushed deeper with the screw 28, the spring 31 is stretched to acquire elastic potential energy. During reset, the spring 31 returns to its initial state. The elastic force of the spring 31 assists the abutment plate 29 in quickly disengaging from the circuit board, reducing disassembly time and improving operating efficiency. During clamping, the spring 31 can absorb some vibration or overload impact, avoiding damage to the surface of the circuit board caused by clamping.

[0037] Unlike traditional processing supports, this embodiment features automated positioning and clamping capabilities, such as... Figure 1-2 As shown, the transmission assembly includes a sliding unit and a hydraulic cylinder 19, and also includes irregularly shaped transmission components that are respectively hinged to the sliding unit and the hydraulic cylinder 19 to enable their movement and cooperation. The irregularly shaped transmission components include a first irregularly shaped transmission component 14 and a second irregularly shaped transmission component 15.

[0038] like Figure 1 As shown, the first wedge-shaped positioning slider 4 and the second wedge-shaped positioning slider 7 are respectively provided with a first slider hinge ear 8 and a second slider hinge ear 9 on their respective ends away from each other. The first slider hinge ear 8 is hinged to a first linkage rod 10, and the other end of the first linkage rod 10 is hinged to a first irregular transmission component 14. The second slider hinge ear 9 is hinged to a second linkage rod 11, and the other end of the second linkage rod 11 is hinged to a second irregular transmission component 15.

[0039] Combination Figure 1-2 As shown, the sliding unit includes a positioning slide rod 20 that is vertically disposed in the center of the open cavity 2 and whose upper surface is connected to the platform 1. A sliding cylinder 21 is slidably connected to the positioning slide rod 20. A first connecting rod 22 and a second connecting rod 23 are respectively hinged to the left and right sides of the sliding cylinder 21. The other end of the first connecting rod 22 is hinged to a first irregular transmission component 14, and the other end of the second connecting rod 23 is hinged to a second irregular transmission component 15.

[0040] Preferably, the first irregularly shaped transmission component 14 and the second irregularly shaped transmission component 15 have the same structure and are symmetrically arranged. Each of the first irregularly shaped transmission component 14 and the second irregularly shaped transmission component 15 is provided with an integrally formed first leg 16, second leg 17 and third leg 18.

[0041] Furthermore, such as Figure 2As shown, the free end of the first leg 16 is hinged to the first linkage rod 10. The lower part of the first leg 16 of the first irregular transmission member 14 is hinged to the first positioning hinge ear 12 on the side wall of the platform 1 via a connecting column formed thereon. The hinge position between the first leg 16 of the first irregular transmission member 14 and the first positioning hinge ear 12 is the pivot point. The lower part of the first leg 16 of the second irregular transmission member 15 is hinged to the second positioning hinge ear 13 on the side wall of the platform 1 via a connecting column formed thereon. Thus, when the first irregular transmission member 14 moves, the hinge position between the first leg 16 of the second irregular transmission member 15 and the second positioning hinge ear 13 is the pivot point.

[0042] Furthermore, the free end of the second leg 17 of the first irregular transmission component 14 is hinged to the free end of the first connecting rod 22, and the free end of the second leg 17 of the second irregular transmission component 15 is hinged to the free end of the second connecting rod 23, thereby forming a transmission connection relationship between the sliding unit and the irregular transmission component.

[0043] The free end of the third leg 18 of the first irregularly shaped transmission component 14 is hinged to the output end of the hydraulic cylinder 19, and the free end of the third leg 18 of the second irregularly shaped transmission component 15 is hinged to the cylinder body end of the hydraulic cylinder 19. The hydraulic cylinder 19 is the power source of the transmission assembly.

[0044] Based on this, the operating principle of this embodiment is as follows:

[0045] In the initial state, the first wedge-shaped positioning slider 4 and the second wedge-shaped positioning slider 7 are far apart from each other, and at this time the sliding cylinder 21 is engaged with the positioning slide rod 20;

[0046] When the hydraulic cylinder 19 is started, the hydraulic cylinder 19 becomes longer as a whole under the extension of its output end, which simultaneously pushes the third leg 18 of the first irregular transmission component 14 and the second irregular transmission component 15 to expand outward, and then pulls the first connecting rod 22 and the second connecting rod 23 respectively through the two second legs 17 to jointly drive the sliding cylinder 21 to move down along the positioning slide rod 20.

[0047] At the same time, hydraulic cylinder 19 also changes its horizontal position to a lower position than its initial state;

[0048] Under the above action conditions, the two first legs 16 respectively push the first wedge-shaped positioning slider 4 and the second wedge-shaped positioning slider 7 through the first slider hinge ear 8 and the second slider hinge ear 9 to clamp them.

[0049] The working principle of the positioning fixture 24 is as described above, and will not be repeated here.

[0050] This application discloses a circuit board processing bracket that combines a frame-shaped support with a clamp-shaped clamping mechanism. The integrated design of the open cavity and transmission components reduces space occupation. The dual clamping of mechanical and hydraulic drives through the wedge-shaped slider and positioning fixture significantly improves the resistance to high-frequency vibration and prevents circuit board misalignment during processing. The hydraulic drive allows the wedge-shaped slider to be infinitely adjustable in spacing, adapting to circuit boards of different sizes and providing strong compatibility.

[0051] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
