Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, and in particular to a multifunctional PCB lamp board fixture suitable for microscopes, mainly used for PCB lamp board inspection in the field of automotive lighting. Background Technology

[0002] The PCB boards used in automotive lights vary in size. After molding, it is necessary to observe the appearance of each component and the solder joints at the connection points under a microscope. Generally, the PCB board is clamped under the microscope. Because the types and shapes of PCB boards are diverse, such as curved, polygonal, and rectangular shapes, and in terms of type, there are circuit boards with raised components soldered on both sides, as well as flexible circuit boards, the existing technology requires different clamping fixtures for different circuit boards. It is impossible to clamp different PCB boards with the same fixture, which leads to reduced testing efficiency.

[0003] In addition, existing PCB lamp board fixtures only support planar fixation and cannot make fine adjustments to the tilt angle of the PCB lamp board. This results in blind spots for observing defects in side solder joints or three-dimensional components (such as cold solder joints or cracks), requiring frequent movement of the PCB lamp board or adjustment of the microscope. This operation is complicated and prone to human error. Utility Model Content

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Example 1

[0027] like Figures 1-3 As shown, a multifunctional PCB lamp board clamp suitable for microscopes includes a base plate 1 and two fixing frames located on the base plate 1. Each of the two fixing frames is connected to a carrying tray. One of the fixing frames is connected to the base plate 1 through a horizontal adjustment component 2 so that the two fixing frames can be brought closer to or further away from each other.

[0028] For ease of description, in the following embodiments, the two fixing frames are respectively named left fixing frame 3 and right fixing frame 4, the carrying tray connected to left fixing frame 3 is named left carrying tray 5, and the carrying tray connected to right fixing frame 4 is named right carrying tray 6. Left fixing frame 3 is fixedly installed to base plate 1, and right fixing frame 4 is connected to base plate 1 through horizontal adjustment component 2.

[0029] The two cargo trays have the same structure. Each cargo tray includes a cargo platform 7 and a baffle 8 located on one side of the cargo platform 7 and extending upward. Anti-slip mats 9 are provided on the opposite surfaces of the two cargo platforms 7. The baffle 8 and the anti-slip mats 9 are located on both sides of the same cargo platform 7. A fixing device 10 is installed on the upper surface of the baffle 8.

[0030] When clamping flexible circuit boards or circuit boards with single-sided soldered raised components, at least one surface of the circuit board must be smooth, so it can be clamped with one side placed on the loading platform 7, such as... Figure 5 As shown, the two ends of the PCB light board 17 are placed on two carrying platforms 7 respectively. Then, the horizontal adjustment component 2 is adjusted to make the two baffles 8 at both ends of the PCB light board 17 abut against each other, and the upper part is pressed and fixed by the fixer 10.

[0031] When mounting circuit boards with double-sided soldered protruding components, the circuit boards cannot be placed stably on the platform 7. Therefore, a clamping method is used on both sides, such as... Figure 4 As shown, the left and right ends of the PCB light board 17 are respectively aligned with the anti-slip pads 9 on both sides. Then, by adjusting the horizontal adjustment component 2, the PCB light board 17 is clamped between the two anti-slip pads 9. The anti-slip function of the anti-slip pads 9 can prevent the PCB light board 17 from slipping.

[0032] The horizontal adjustment component 2 is used to adjust the horizontal position of the right fixed bracket 4. It can be a linear motor or a cylinder. Due to the small adjustment distance, this embodiment uses manual adjustment, specifically including a sliding knob 201, a gear 202, and a rack 203. The rack 203 is mounted on the fixed bracket, and the gear 202 is mounted on the sliding knob 201. The sliding knob 201 is rotatably connected to the base plate 1, and the gear 202 and rack 203 mesh with each other. Figure 3 As shown, a column 11 is provided on the base plate 1, and a sliding knob 201 is installed on the column 11. A rack 203 is provided on the side of the right fixed frame 4. The length direction of the rack 203 is the same as the movement direction of the right fixed frame 4. When the sliding knob 201 is rotated, the gear 202 rotates, thereby driving the rack 203 and the right fixed frame 4 to move forward or backward.

[0033] To ensure the straightness of the movement of the right fixed frame 4, two slide rails 101 can be symmetrically arranged on the base plate 1. The fixed frame connected to the horizontal adjustment component 2 is slidably connected to the slide rails 101, that is, the right fixed frame 4 is slidably connected to the slide rails 101.

[0034] The anti-slip mat 9 is made of silicone material with anti-slip properties. In further design, anti-slip textures can also be set on the surface of the anti-slip mat 9.

[0035] The retainer 10 can be a clamping cylinder or a manual quick clamping clamp.

[0036] Example 2

[0037] Based on Embodiment 1, the tray is rotatably connected to the mounting frame, one of which is equipped with an angle adjustment component 12 for driving the tray to rotate. The angle adjustment component 12 can adjust the tilt angle of the tray, facilitating multi-dimensional observation of the solder joints and fine structures on the side of components during microscopic observation, without the need for frequent movement of the PCB light board 17 or adjustment of the microscope.

[0038] The rotatable connection between the tray and the frame can be achieved through the following structure: the end of the frame facing the tray has a groove 13, a bearing 14 is installed in the groove 13, and the tray and the inner ring of the bearing 14 are interference-fitted.

[0039] The angle adjustment component 12 may, but is not limited to, adopt the following structure: such as Figure 2 As shown, the system includes an adjustment knob 1201, an adjustment rod 1202, a worm gear 1203, a worm 1204, and a rotating shaft 1205. The adjustment knob 1201 and the worm gear 1203 are located at opposite ends of the adjustment rod 1202. The adjustment rod 1202 is rotatably connected to a fixed frame or a base plate 1. The fixed frame has a shaft hole 15 at its center. The rotating shaft 1205 passes through the shaft hole 15 and is fixed to the end of the carrying tray. The worm 1204 is mounted on the rotating shaft 1205, and the worm gear 1203 engages with the worm 1204. When the adjustment knob 1201 is rotated, the adjustment rod 1202 drives the worm gear 1203 to rotate, thereby driving the worm 1204 and the rotating shaft 1205 to rotate, thus realizing the rotational movement of the carrying tray.

[0040] Example 3

[0041] Based on the above embodiment, a fixing plate 16 is also installed on one side of the base plate 1. The fixing plate 16 has fixing holes 1601 corresponding to the microscope interface. The fixing holes 1601 integrate a standard metallurgical microscope interface (such as an M6 threaded hole), which can be directly installed on the stage of existing equipment, and has good compatibility.

[0042] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
