Technical Field

[0001] This utility model relates to the technical field of camera module testing equipment, specifically a camera module power-on timing test device. Background Technology

[0002] In the mass production testing of camera modules, traditional power-on timing test devices mostly adopt a single-station design, which means that only one module can be fixed and tested at a time. With the surge in demand for camera modules in consumer electronics, automotive security and other fields, the single-station testing mode can no longer meet the requirements of mass production efficiency.

[0003] In existing technologies, if multiple modules need to be tested simultaneously, they are often manually placed and fixed one by one before testing. When facing the mass production requirements of camera modules, the single-station testing method will significantly extend the production cycle and become a key bottleneck restricting the improvement of module mass production efficiency. Therefore, we need to provide a camera module power-on timing test device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a camera module power-on timing test device, comprising:

[0024] The test bench 1, the tester 2, the mold plate 3, and the positioning mechanism 4 are provided. The test bench 1 is equipped with the tester 2 for testing camera modules. The test bench 1 is equipped with the mold plate 3 for placing camera modules. The positioning mechanism 4 is installed on the top of the mold plate 3 and is used to fix multiple camera modules.

[0025] The positioning mechanism 4 includes a placement slot 41, a contactor 42, and a clamping plate 43. The top of the mold plate 3 is provided with multiple placement slots 41. The placement slot 41 is provided with a contactor 42 for fixing the camera module. The placement slot 41 is provided with two clamping plates 43 for clamping the camera module. The contactor 42 works in conjunction with the two clamping plates 43.

[0026] Specifically, the positioning mechanism 4 is set on the mold plate 3, which can fix multiple camera molds that need to be tested at one time. Using the tester 2, multiple camera molds can be tested. Through the multiple sets of placement slots 41 on the mold plate 3 and the positioning components, six modules can be accurately fixed at one time, saving the time of repeated clamping in traditional single station. The positioning mechanism 4 can adapt to the slight differences of different sized modules through the elastic compression of the contactor 42 and the clamping of the clamping plate 43, avoiding the positioning deviation of manual fixing, ensuring stable contact between the module interface and the tester 2, and reducing repeated testing due to poor contact.

[0027] The contactor 42 includes a groove 421, a contact strip 422 and a spring 423. The groove 421 is opened in the mold plate 3, and the contact strip 422 is installed inside by the spring 423. The contact strip 422 passes through one end of the groove 421 and is used to squeeze the camera module.

[0028] Furthermore, the groove 421 is opened within the mold plate 3 and is horizontally arranged. The groove 421 is made of aluminum alloy and is anodized. The abutment strip 422 is made of ABS engineering plastic. One end of the strip near the camera module is provided with a rubber buffer layer, and the other end is connected to the bottom of the groove 421 by a spring 423. The abutment strip 422 passes through the end of the groove 421 near the center of the placement slot 41. When the camera module is placed into the placement slot 41, the preload of the spring 423 pushes the abutment strip 422 to press against the side of the camera module, thus fixing it in place.

[0029] A guide rod 5 is fixedly installed inside the groove 421, and a guide groove 6 is opened in the abutment strip 422 to slide with the guide rod 5, and a spring 423 is movably sleeved on the surface of the guide rod 5.

[0030] It is worth noting that the contact strip 422 has a guide groove 6 that fits with the guide rod 5 with a clearance of 0.1-0.2mm; the spring 423 is a nickel-plated compression spring 423 with a wire diameter of 0.8-1.2mm, which is movably sleeved on the surface of the guide rod 5 and its two ends are respectively attached to the bottom of the groove 421 and the end face of the contact strip 422; the fit between the guide rod 5 and the guide groove 6 restricts the contact strip 422 to move only in the horizontal direction, avoids the spring 423 from being deflected by force and causes unstable fixation, and solves the problem of module positioning deviation caused by the tilt of the contact strip 422.

[0031] It also includes a transmission component 7, which includes a push rod 71 and a transmission rod 72. The push rod 71 is installed in the placement slot 41 and slidably installed in the mold plate 3. The push rod 71 is hinged to both sides of the transmission rod 72, and one end of the transmission rod 72 is hinged to the clamping plate 43.

[0032] It should be noted that the push rod 71 is made of 45# steel and chrome-plated. It is horizontally slidably installed in the pre-set through hole in the mold plate 3, and the through hole is connected to the placement groove 41. The transmission rod 72 is made of high-strength nylon, and its two ends are respectively hinged to the push rod 71 and the clamping plate 43 through stainless steel pins. The fit clearance between the pin and the hinge hole is 0.05-0.1mm. When the contact strip 422 pushes the camera module to squeeze the push rod 71, the push rod 71 moves axially along the through hole. The axial force is converted into the clamping force of the clamping plate 43 through the transmission rod 72, realizing the secondary fixation of mechanical linkage and solving the problem of unstable fixation in one direction.

[0033] Each of the two clamping plates 43 is fixedly installed with a sliding rod 8 on the opposite side, and the placement groove 41 is provided with sliding grooves 9 on both sides for the sliding rod 8 to slide.

[0034] Furthermore, silicone anti-slip pads are provided on the opposite sides of the two clamping plates 43, and stainless steel slide rods 8 are vertically fixed on the opposite sides; the inner walls on both sides of the placement groove 41 are provided with slide grooves 9 that fit with the slide rods 8 with clearance, and the tolerance between the diameter of the slide rod 8 and the width of the slide groove 9 is H7 / g6; the fit between the slide rod 8 and the slide groove 9 restricts the clamping plates 43 to move only in a direction perpendicular to the push rod 71, ensuring that the clamping force of the clamping plates 43 on the module is always horizontal and symmetrical, avoiding poor interface contact caused by the force deviation of the module, and improving the fixing stability.

[0035] The push rod 71 has a bonding plate 10 fixedly installed on one end near the camera module, and the other end of the push rod 71 passes through one side of the mold plate 3 and extends therefrom.

[0036] The push rod 71 has a brass bonding plate 10 vertically fixed to one end of its surface near the camera module. A 0.5mm thick polytetrafluoroethylene (PTFE) gasket is attached to the surface of the bonding plate 10. The other end of the push rod 71 passes through one side of the mold plate 3 and extends to form an operating end, which has anti-slip texture. The bonding plate 10 increases the contact area between the push rod 71 and the module, avoiding damage to the module due to excessive local pressure. The PTFE gasket reduces the risk of scratching the module surface. At the same time, manually pulling the operating end can forcibly open the clamping plate 43, making it convenient to pick up and put down the module.

[0037] The bottom of the test bench 1 is equipped with a driver for rotating the mold plate 3;

[0038] Specifically, the stepper motor is fixed to the bottom of the test bench 1 via a flange, and its output shaft is rigidly connected to the output rod via a coupling. The top of the output rod is fixed to the center of the mold plate 3 via bolts. The annular track is made of high manganese steel and is concentrically fixed to the bottom of the mold plate 3. Eight stainless steel columns are evenly distributed on the top of the test bench 1. Polyurethane balls are rotatably mounted on the top of the columns via bearings. The balls are embedded in the annular track and roll in contact with the inner wall of the track. The stepper motor drives the mold plate 3 to rotate precisely. The annular track and the balls cooperate to bear the radial load of the mold plate 3, solving the problem of shaking during high-speed rotation and ensuring that the module accurately aligns with the tester 2.

[0039] The tester 2 involved in this application is implemented using existing mature technology and is connected to an external PLC controller and power supply. This is a conventional technical means in this field, so its specific circuit connection, control logic and working process will not be described in detail.

[0040] The driver of this device can drive the mold disk 3 to rotate, moving the camera mold to be tested under the tester 2 for testing. The driver includes a stepper motor and an output rod. The stepper motor is fixed to the bottom of the test platform 1, and the output rod is installed at the output end. The output rod is fixed to the top of the mold disk 3 at the axis, and a ring track is fixedly installed at the bottom of the mold disk 3. A ring-shaped column is fixedly installed on the top of the test platform 1, and a ball bearing is rotatably installed on the top of the column. The ball bearing is in the ring track. When fixing the camera module, the contact bar 422 is first pushed to move in the groove 421, and the spring 4 is squeezed. 23. Install the camera module in the placement slot 41, release the push on the abutment strip 422, the spring 423 pushes the abutment strip 422, the abutment strip 422 squeezes the camera module to move, and squeezes the push rod 71. The movement of the push rod 71 will drive the two transmission rods 72 to rotate, thereby controlling the two clamping plates 43 to move closer to each other, squeezing and fixing the camera module. It can adapt to the quick fixing of camera modules of different specifications. One end of the push rod 71 passes through one side of the mold plate 3. The push rod 71 can be pulled to drive the transmission rod 72 to swing, so that the two clamping plates 43 move away from each other, which facilitates the installation of the camera module.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
