Description

Technical Field

[0001] The utility model relates to the technical field of camera testing equipment, in particular to a belt pressing device for camera module testing. Background Art

[0002] With the popularity of electronic video products such as smart phones, tablet computers, and dashcams in recent years, the market demand for camera modules has been growing, which has led to the continuous expansion of camera module manufacturers. Correspondingly, the demand for automatic connection structures of camera modules is also growing. Currently, most of the camera module test fixtures on the market are inherited from the early days, and the camera modules need to be fixed manually, which is inefficient and labor-intensive for operators. Moreover, when the camera module needs to be rotated or other movements during testing, it is easy to shake, affecting the accuracy of the test.

[0003] In order to solve the above problems, the utility model patent with announcement number CN205620671U discloses a camera module test fixture, including a base, a picture taking board card is arranged in the base, at least one module fixing device is arranged on the base, a picture taking connection device is connected to the bottom of the module fixing device, the picture taking connection device is connected to the picture taking board card, a pressure plate is arranged above the module fixing device, and the pressure plate is connected to a driving device; under the driving action of the cylinder, the pressure plate presses the camera module in a fixed position, which not only accurately fixes the camera module, but also greatly increases the detection efficiency, and the test conversion between lenses of various specifications is more flexible; through the coordinated connection of the ball bearing and the pulley, the rotation of the base by 90 degrees is realized, so that the camera module can be tested in a vertical state, thereby improving the detection accuracy.

[0004] However, the above-mentioned clamp directly uses a driving device to drive the pressing plate to press the camera, which may easily cause scratches on the surface of the camera and affect product quality. Utility Model Content

[0005] The utility model aims to provide a belt pressing device for camera module testing, which can protect the surface of the camera module from being scratched and avoid affecting product quality by soft contact and pressing between the belt and the camera module.

[0006] The utility model is achieved in this way:

[0007] A belt clamping device for camera module testing includes a test base, two pulleys are rotatably connected to the two sides of the test base, a tensioning mechanism is fixedly installed on the bottom of the test base, the pulley is connected to the tensioning mechanism through a belt, and the belt for clamping the camera module covers the top of the test base.

[0008] Furthermore, a limit baffle is movably embedded on the test base, the bottom of the limit baffle is elastically connected to the test base via a spring, and the top of the limit baffle is rotatably connected to a roller, which abuts against the belt.

[0009] Furthermore, the belt is fixedly connected to the tensioning mechanism.

[0010] Furthermore, the tensioning mechanism adopts a cylinder, and the belt is fixedly connected to the protruding end of the piston rod of the cylinder.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In actual application, the camera module is placed on the test base manually or by a robot, and the tensioning mechanism stretches the belt downward so that the belt is tightened and pressed down to fix the camera module on the test base. After the entire mechanism is powered on, the camera module is tested. After the test is completed, the tensioning mechanism retracts the belt so that the belt loosens the camera module, and the camera module is taken out manually or by a robot, and then the above process is repeated. The pulley is used to reduce the resistance encountered when the belt is tightened and retracted. The utility model can protect the surface of the camera module from being scratched and avoid affecting product quality by soft contact and compression between the belt and the camera module.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0018] In actual application, the camera module is placed on the test base 1 manually or by a robot, and the tensioning mechanism 3 stretches the belt 4 downward so that the belt 4 is tightened and pressed down to fix the camera module on the test base 1. After the entire mechanism is powered on, the camera module is tested. After the test is completed, the tensioning mechanism 3 retracts the belt 4 so that the belt 4 loosens the camera module, and the camera module is taken out manually or by a robot, and then the above process is repeated. The pulley 2 is used to reduce the resistance encountered when the belt 4 is tightened and retracted. The utility model can protect the surface of the camera module from being scratched and avoid affecting product quality by soft contact and pressing between the belt 4 and the camera module.

In this embodiment, the camera module is placed between the limit baffles 5 on the test base 1 manually or by a manipulator, and the camera module is limited by the limit baffle 5 to prevent the camera module from shifting during the pressing process. When the tensioning mechanism 3 stretches the belt 4 downward, the belt 4 simultaneously presses the limit baffle 5 downward to compress the spring 6. After the test is completed, the tensioning mechanism 3 retracts the belt 4, and the spring 6 recovers its deformation to support the belt 4, which is convenient for taking and placing the camera module. The roller 7 is used to reduce the friction between the limit baffle 5 and the belt 4.

[0020] See also Figure 1 , the belt 4 is fixedly connected to the tensioning mechanism 3. In this embodiment, the belt 4 is fixed to the tensioning mechanism 3 to prevent the belt 4 from being offset when the tensioning mechanism 3 stretches the belt 4, so that the through hole set on the belt 4 for the camera module to work is offset.

[0021] See also Figure 1 The tensioning mechanism 3 adopts a cylinder, and the belt 4 is fixedly connected to the extended end of the piston rod of the cylinder.
