Description

Technical Field

[0001] This utility model belongs to the field of camera modules, specifically, it relates to a camera module testing tool. Background Technology

[0002] During the production process of camera modules, it is necessary to test each component in the camera module, so corresponding camera module testing tools are used.

[0003] Patent application CN220325682U discloses a camera module testing aid. Paragraph 0032 of the specification discloses that when testing a camera module, the distance between four limiters can be adjusted according to the size of the lens. During adjustment, simply rotating the gears forward or backward will cause one of the drive mechanisms to work with the ring toothed belt to drive the other three drive mechanisms to rotate simultaneously, causing the four limiters to extend or retract. First, the distance between the four limiters should be greater than the size of the lens. Then, the lens to be tested is placed between the four limiters. Rotating the gears will cause the four limiters to retract. Then, the lens is pressed and fixed by various pressure plates on the compression plate. In this way, lenses of various sizes can be fixed, making the whole process more convenient and flexible.

[0004] However, in practical applications, the camera module inside the ring frame needs to be clamped by one side of the extrusion plate. Because the camera module is irregularly shaped, it is easy for one side of the extrusion plate to not contact the surface of the camera module. Therefore, it is impossible to clamp the camera module by one side of the extrusion plate, which will cause the camera module to shake during testing and affect the testing effect.

[0005] To address these shortcomings, a camera module testing tool is proposed. Utility Model Content

[0033] Working principle:

[0034] First, place the camera module body on the upper side of the test bench 100. Then, slide the U-shaped rod 115 upwards. One end of the U-shaped rod 115 releases the positioning of the sliding block 104. Then, slide the U-shaped rod 115 again. The U-shaped rod 115 drives the sliding block 104 to slide inside the guide groove 102. The sliding block 104 drives the arc plate 108 to slide towards the camera module body. The arc plate 108 drives one end of the positioning rod 110 to position the camera module body on the upper side of the test bench 100. Then, the camera module body can be tested.

[0035] The positioning rod 110 is set so that one end of the positioning rod 110 slides towards the camera module body under the action of the arc plate 108, and the camera module body is fixed on the upper side of the test bench 100 through one end of the positioning rod 110, which reduces the problem of shaking during the testing of the camera module body and improves the testing effect of the camera module body.

[0036] To make the sliding block 104 in this embodiment slide more stably on one side of the guide groove 102, the following structure is used for improvement, such as... Figure 1-4As shown, in this embodiment, a first guide rod 103 is fixedly fitted inside the guide groove 102. A first guide hole 105 is provided on one side of the sliding block 104. The first guide rod 103 is located inside the first guide hole 105. A first spring 106 is fixedly fitted between the inner sidewall of the guide groove 102 and one side of the sliding block 104. The first spring 106 is sleeved on the periphery of the first guide rod 103. A connecting rod 107 is fixedly fitted on one side of the sliding block 104. The outer sidewall of the arc plate 108 is fixedly fitted on one end of the connecting rod 107. Two second guide holes 109 are provided on one side of the arc plate 108. A positioning rod 110 is slidably fitted inside the second guide holes 109. A fixing plate 111 is fixedly fitted on one end of the positioning rod 110. A second guide hole 109 is fixedly fitted between one side of the fixing plate 111 and the outer sidewall of the arc plate 108. Spring 112 is sleeved around the positioning rod 110. Two third guide holes 113 are opened on the upper side of the sliding block 104. Two second guide rods 114 are fixedly fitted on the outer wall of the U-shaped rod 115.

Fixing blocks 117 are fixedly fitted on both sides of the sliding block 104. A fourth guide hole 119 is opened on one side of the fixing block 117. One end of the U-shaped rod 115 is slidably fitted inside the fourth guide hole 119. Multiple support feet 101 are fixedly fitted at the bottom of the test platform 100. A placement platform 118 is fixedly fitted on the upper side of the test platform 100.

[0037] In this embodiment, the U-shaped rod 115 is first slid upwards. The U-shaped rod 115 drives the second guide rod 114 to slide inside the third guide hole 113 and stretch the second spring 112. The U-shaped rod 115 drives the pointed end to release the positioning of the test platform 100. Then, the sliding block 104 is slid. The bottom of the sliding block 104 slides inside the guide groove 102. The sliding block 104 slides inside the first guide rod 103 through the first guide hole 105 and stretches the first spring 106. The sliding block 104 drives the arc plate 108 to slide through the connecting rod 107. The arc plate 108 drives one end of the positioning rod 110 to be positioned on the camera module body. Then, the camera module body can be tested.

[0038] The guide groove 102 is provided so that the sliding block 104 slides inside the guide groove 102 under the action of the U-shaped rod 115, and the guide groove 102 guides the sliding direction of the sliding block 104, reducing the problem of the sliding block 104 tilting during sliding and improving the stability of the sliding block 104 during sliding.
