[0001] The utility model relates to the technical field of circuit board detection, in particular to a circuit board clamping mechanism. Background Art

[0002] In the electronics manufacturing industry, first-article inspection (FII) is an essential step to ensure product quality. Particularly during the circuit board production process, FAI can help promptly identify factors that could affect product quality, thereby preventing the production of a large number of substandard products. To conduct effective FAI, the circuit boards must be precisely secured to the inspection equipment, typically using specialized clamping mechanisms.

[0003] Current clamping mechanisms on the market are primarily designed for circuit boards within a specific thickness range, making them inflexible and inefficient for use with boards of varying thicknesses. Due to the wide range of thicknesses found in modern electronic products, traditional clamping methods often struggle to adapt to this diversity. This can lead to insecure or even impossible fixation in practice, impacting the accuracy and efficiency of first-article inspection. Utility Model Content

[0030] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a circuit board clamping mechanism.

[0031] A circuit board clamping mechanism includes a positioning chuck 1 and two relatively arranged fixed clamping components 2, the positioning chuck 1 is provided with a guide rail 3 and a rotating rod 4, the fixed clamping component 2 is slidably connected to the guide rail 3, and the two fixed clamping components 2 are enclosed to form an accommodating space 5, and the fixed clamping components 2 each include a guide member 201, a clamping plate 202 and a top plate 203, the two guide members 201 are respectively sleeved on the two ends of the rotating rod 4, the upper end of the guide member 201 is provided with a first guide groove 204, and the two guide members 201 are provided with a second guide groove 205 on the side close to the accommodating space 5, and the first guide groove 204 has a second guide groove 206. An inclined section 206, the first inclined section 206 gradually approaches the accommodating space 5, the second guide groove 205 has a second inclined section 207, the second inclined section 207 gradually moves away from the rotating rod 4, the bottom of the clamping plate 202 is provided with a first guide rod 208 in the vertical direction, the first guide rod 208 extends into the first guide groove 204, the top of the clamping plate 202 is provided with a clamping member 209 near one end of the accommodating space 5, the bottom of the top plate 203 is provided with a second guide rod 210 in the horizontal direction, the second guide rod 210 extends into the second guide groove 205, and the top plate 203 is located at the bottom of the clamping member 209.

[0032] The present invention includes a guide member 201, a clamping plate 202 and a top plate 203 through the fixed clamping assembly 2. First, the distance between the two fixed clamping assemblies 2 is adjusted by the guide rail 3, and the circuit board is placed on the two top plates 203. Since the guide members 201 are respectively sleeved on both ends of the rotating rod 4, the upper ends of the guide members 201 are provided with a first guide groove 204, and the two guide members 201 are provided with a second guide groove 205 on the side close to the accommodating space 5. The first guide groove 204 has a first inclined section 206, and the first inclined section 206 gradually approaches the accommodating space 5. When clamping, the rotating rod 4 is rotated to drive the guide member 201 to rotate, and the first guide rod 20 8 moves along the first guide groove 204, passes through the first inclined section 206, and the first guide rod 208 moves toward the accommodating space 5. The clamping piece 209 extends, and the second guide rod 210 moves along the second guide groove 205. Since the second guide groove 205 has a second inclined section 207, the second inclined section 207 gradually moves away from the rotating rod 4. The second guide rod 210 passes through the second inclined section 207, which will cause the top plate 203 to move upward, and then lift the circuit board to abut against the bottom surface of the clamping piece 209, completing the clamping of the circuit board. The utility model can clamp circuit boards of different thicknesses, has good clamping stability, is easy to operate, and has high accuracy and efficiency in first-article inspection.

[0033] In the circuit board clamping mechanism described in this embodiment, the fixing clamping assembly 2 includes a base 211 , and the guide member 201 , the clamping plate 202 , and the top plate 203 are all disposed inside the base 211 .

[0034] In the circuit board clamping mechanism described in this embodiment, a positioning plate 212 is provided on the top of the base 211, a plurality of first limiting blocks 213 are provided on the bottom of the positioning plate 212, a plurality of first movable grooves 214 are provided on the clamping member 209, and the clamping member 209 is located between the positioning plate 212 and the base 211. The first limiting blocks 213 are respectively inserted into the first movable grooves 214, and the length of the first movable grooves 214 along the radial direction of the rotating rod 4 is greater than the length of the first limiting blocks 213 along the radial direction of the rotating rod 4. Specifically, through the above arrangement, the first limiting blocks 213 can activate the positioning function of the clamping member 209, and the length of the first movable grooves 214 along the radial direction of the rotating rod 4 is greater than the length of the first limiting blocks 213 along the radial direction of the rotating rod 4, so that the clamp can extend radially along the rotating rod 4 into the accommodating space 5, and the positioning plate 212 can also limit the clamping member 209 in the vertical direction.

[0035] In this embodiment of the circuit board clamping mechanism, a plurality of ejector pins 213 are disposed on the top of the top plate 203. A board placement slot 215 is disposed on the end of the base 211 near the accommodating space 5. The board placement slot 215 is provided with a plurality of through-holes 216. The ejector pins 213 are disposed corresponding to the through-holes 216, and the ejector pins 213 are inserted into the through-holes 216 one by one. Specifically, when the top plate 203 moves upward, the ejector pins 213 extend from the through-holes 216 one by one, lifting the circuit board until it abuts against the clamping member 209.

[0036] In the circuit board clamping mechanism described in this embodiment, the top plate 203 is provided with a plurality of second movable slots 217, and the base 211 is provided with a plurality of second limiting blocks 218. The second limiting blocks 218 are disposed one by one through the second movable slots 217, and the vertical length of the second movable slots 217 is greater than the vertical length of the second limiting blocks 218. Specifically, this arrangement effectively guides and limits the displacement of the top plate 203.

[0037] In the circuit board clamping mechanism described in this embodiment, the first inclined section 206 is located at the front end of the second inclined section 207. This allows the first guide rod 208 to pass through the first inclined section 206 before the second guide rod 210 passes through the second inclined section 207 when the rotating rod 4 drives the guide member 201 to rotate. Specifically, the first guide rod 208 passes through the first inclined section 206, allowing the clamping member 209 to extend from the upper end of the top plate 203. The second guide rod 210 then passes through the second inclined section 207, lifting the circuit board until it abuts against the clamping member 209, achieving clamping.

[0038] It is understandable that in some embodiments, the time it takes for the first guide rod 208 to pass through the first inclined section 206 and the time it takes for the second guide rod 210 to pass through the second inclined section 207 can be the same to improve clamping efficiency.

[0039] In the circuit board clamping mechanism described in this embodiment, the rotating rod 4 has a hexagonal cross-section, which enables the fixed clamping assembly 2 to move radially along the rotating rod 4 and also drives the guide member 201 to rotate via the rotating rod 4 .

[0040] In the circuit board clamping mechanism described in this embodiment, a rocker 6 is provided at one end of the rotating rod 4. Specifically, the above arrangement facilitates the rotation of the rotating rod 4.

[0041] Specifically, a slider 219 is provided at the bottom of the fixed clamping assembly 2 , and the slider 219 is slidably connected to the guide rail 3 .

[0042] In the circuit board clamping mechanism described in this embodiment, the clamping plate 202 is provided with a second movable groove, and the base 211 is provided with a guide post 220, which is inserted into the second movable groove. Specifically, this arrangement further guides and limits the displacement of the clamping plate 202.

[0043] In the circuit board clamping mechanism described in this embodiment, one of the two fixed clamping components 2 is fixedly connected to the positioning clamping plate 1, and the other is slidably connected to the guide rail 3. Specifically, different circuit board sizes can be accommodated by adjusting one fixed clamping component 2.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
