[0022] The following specific implementation content provides various different embodiments or examples for implementing the present utility model. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures being discussed.
[0023] As Figures 1 - 5 shown, a vision inspection fixture for an optical module chip includes a circular support base 1. On the upper end surface of the circular support base 1, four straight chutes 2 are evenly distributed along the circumference. A first slider 3 and a second slider 4 are slidably disposed in each of the straight chutes 2. The first slider 3 is located inside the second slider 4, and a clamping plate 5 is disposed on the first slider 3. A fixed seat 6 is disposed on the second slider 4, and a spacing adjustment mechanism for adjusting the spacing between the first slider 3 and the second slider 4 is disposed on the fixed seat 6. A driving mechanism is further disposed on the circular support base 1, and the driving mechanism is used to drive all the second sliders 4 to move inward or outward simultaneously along their respective straight chutes 2.
[0024] In the present utility model, when clamping the chip, the chip is placed on the circular support base 1. Then, the positions of the first slider 3 and the clamping plate 5 can be adjusted first through the spacing adjustment mechanism. Subsequently, the four second sliders 4 can be driven by the driving mechanism to move inward along the straight chutes 2 simultaneously. The second slider 4 can drive the first slider 3 and the clamping plate 5 to move simultaneously through the spacing adjustment mechanism, so as to clamp the chip through the clamping plate 5, and thus it can be suitable for clamping and detecting chips of different types and specifications, and the operation is convenient, improving the test efficiency.
[0025] See Figures 1 - 5 shown, the spacing adjustment mechanism includes a screw rod 21 movably penetrating through the fixed seat 6. Nuts 22 are threadedly connected to both sides of the fixed seat 6 on the screw rod 21. A rotating block 23 is disposed at the inner end of the screw rod 21, and the rotating block 23 is rotatably mounted on the clamping plate 5. When adjusting the position of the first slider 3, the screw rod 21 is passed through the fixed seat 6, so that the clamping plate 5 and the first slider 3 can be pushed to move through the screw rod 21. After the adjustment is completed, the two nuts 22 on both sides can be directly tightened.
[0026] In order to facilitate the penetration of the screw rod 21, a push button 31 is disposed at the outer end of the screw rod 21.
[0027] Further, a rubber pad 41 is provided inside the clamping plate 5, so as to protect the chip through the rubber pad 41 and avoid pinching the chip.
[0028] See Figures 1 - 3 As shown, the driving mechanism includes a worm gear 51 coaxially arranged in the circular support base 1. A worm 52 meshing with the worm gear 51 is also rotatably installed in the circular support base 1. A rotating disk 53 is provided at the upper end of the worm gear 51. A plurality of inclined slots 54 corresponding to the straight slots 2 are arranged along the circumference on the rotating disk 53. A guiding column 55 is provided at the lower end of the second slider 4, and the guiding column 55 is arranged in the inclined slot 54.
[0029] The working principle of the driving mechanism is as follows: The rotation of the worm 52 cooperates with the worm gear 51 to drive the rotation of the worm gear 51. The rotation of the worm gear 51 drives the synchronous rotation of the rotating disk 53. Then, through the cooperation of the inclined slot 54 and the guiding column 55, the second slider 4 is driven to slide along the straight slot 2. The second slider 4 can drive the first slider 3 and the clamping plate 5 to slide simultaneously through the spacing adjustment mechanism. Since the worm gear 51 and worm 52 mechanism has self-locking property, the chip is clamped by the clamping plate 5.
[0030] To facilitate the rotation of the worm 52, one end of the worm 52 extends outside the circular support base 1 and is provided with a knob 61.
[0031] In the present utility model, a support base 71 for supporting the circular support base 1 is further provided on the lower side of the circular support base 1.
[0032] Further, a central shaft 81 is coaxially arranged on the lower side of the circular support base 1. The central shaft 81 rotatably extends into the support base 71. A first gear 91 is arranged on the central shaft 81. A motor 92 is arranged on the support base 71. A second gear 93 capable of meshing with the first gear 91 is arranged on the output shaft of the motor 92.
[0033] Thus, through the operation of the motor 92, the second gear 93 is driven to rotate. The second gear 93 meshes with the first gear 91 to drive the central shaft 81 and the circular support base 1 to rotate, thereby facilitating the detection of the chip.
[0034] In the present utility model, mounting plates 10 are symmetrically arranged on the outer side of the support base 71. Mounting holes 11 are arranged on the mounting plates 10. The support base 71 is fixed on the workbench by screws passing through the mounting holes 11. The structure is simple and the installation is convenient.
