Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-station testing technology, and more specifically, to a multi-station testing device for AR glasses circuit boards. Background Technology
[0002] In the manufacturing process of AR glasses, the quality inspection of circuit boards is crucial, directly affecting the performance and stability of the AR glasses. Currently, circuit board inspection equipment on the market has many problems. Some traditional inspection equipment uses a single-station inspection method, inspecting only one circuit board at a time, resulting in low inspection efficiency. In large-scale production, the inspection speed is far from meeting production demands, leading to extended production cycles and increased costs.
[0003] Some testing equipment performs poorly in terms of accuracy. Due to the lack of precise positioning and testing methods, it is difficult to accurately detect minute defects and complex locations on circuit boards, which can easily lead to missed detections or misjudgments, allowing defective products to enter subsequent production stages and affecting product quality.
[0004] The loading and unloading processes of existing equipment are not efficient or stable enough. The loading mechanism of some equipment cannot accurately position the circuit boards, resulting in deviations in the position of the circuit boards during the testing process and affecting the test results; while the unloading process may have problems such as jamming and falling, which not only reduces production efficiency but may also damage the circuit boards.
[0005] Therefore, a multi-station testing device for AR glasses circuit boards is proposed. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-station testing device for AR glasses circuit boards to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-station testing device for AR glasses circuit boards, comprising a cabinet, a testing chamber at the top of the cabinet, a testing mechanism installed at the top of the testing chamber, a camera installed on the testing mechanism, a laser rangefinder installed on one side of the camera, an electric push rod installed on one side of the laser rangefinder, a testing head installed at the end of the electric push rod, multiple workstation slots opened in the testing chamber, each workstation slot being equipped with a loading / unloading mechanism, and each loading / unloading mechanism being equipped with a fixture.
[0008] By placing the AR glasses circuit board on a fixture, the circuit board is fixed in place by a vacuum pump. Then, under the operation of the loading and unloading mechanism, it moves to the inspection position. The inspection mechanism operates, allowing the camera to acquire images of the circuit board for visual inspection. A laser rangefinder is used to position and adjust the circuit board, and the distance between each point and the inspection head is measured. Then, by extending and retracting the electric push rod, the inspection head can perform multi-point inspection of the circuit board. Due to the setting of multiple workstation slots, continuous loading and unloading can be carried out, improving inspection efficiency.
[0009] Preferably, each of the fixtures is connected to an air pipe, and each of the air pipes is connected to a vacuum pump.
[0010] Preferably, the fixture includes a fixed plate, on which multiple limiting blocks are mounted, and multiple adsorption holes are opened on the fixed plate. Each adsorption hole is connected to a branch pipe, and all the branch pipes are connected to an air tube.
[0011] Preferably, the testing mechanism includes a first moving module, a crossbeam, a second moving module, and a moving base. There are two first moving modules, which are installed in parallel at the top of the testing chamber. The two first moving modules are connected to the crossbeam. The second moving module is installed on the crossbeam, and the moving base is installed on the second moving module.
[0012] Preferably, an electric actuator is installed at the bottom of the movable base, and a detection head is installed at the end of the electric actuator. A laser rangefinder and a camera are provided on one side of the electric actuator.
[0013] Preferably, the loading and unloading mechanism includes a base, a motor, a lead screw, a slide rail, and a slide block. The base is installed in the work station slot, the motor is installed at one end of the base, the output end of the motor is connected to the lead screw, slide rails are provided on both sides of the lead screw, the slide block is sleeved on the lead screw, and the slide block is slidably connected to the two slide rails. A fixture is installed on the slide block.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. By setting up multiple workstation slots in the testing chamber, and cooperating with the loading and unloading mechanism, continuous loading and unloading can be achieved. Compared with the traditional single-station testing method, the testing efficiency is greatly improved and the waiting time is reduced, which can meet the needs of rapid testing of AR glasses circuit boards in large-scale production.
[0016] 2. The testing mechanism is equipped with a camera, laser rangefinder, and electric actuator. The camera captures images of the circuit board for visual inspection, the laser rangefinder positions and adjusts the circuit board and measures the distance between each point and the testing head, and the electric actuator, in conjunction with the testing mechanism, flexibly moves the testing head in three-dimensional space to achieve precise testing of different points on the circuit board, ensuring the accuracy of the test results.
[0017] 3. The fixture is connected to a vacuum pump via an air pipe. It uses adsorption holes to adsorb and fix the circuit board, and uses limit blocks to limit the edge of the circuit board. This ensures stable movement of the circuit board during loading and unloading, improves loading accuracy, and thus enhances the accuracy of testing. Attached Figure Description

[0024] 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.
[0025] As attached Figure 1-3The AR glasses circuit board multi-station inspection equipment shown includes a cabinet 1, an inspection chamber 2 at the top of the cabinet 1, an inspection mechanism 3 at the top inside the inspection chamber 2, a camera 7 on the inspection mechanism 3, a laser rangefinder 8 on one side of the camera 7, an electric push rod 9 on one side of the laser rangefinder 8, an inspection head 10 at the end of the electric push rod 9, and multiple workstation slots 4 opened in the inspection chamber 2. Each workstation slot 4 is equipped with a loading / unloading mechanism 5, and each loading / unloading mechanism 5 is equipped with a fixture 6.
[0026] In practice, the AR glasses circuit board is placed on the fixture 6. Under the action of the vacuum pump, the AR glasses circuit board is fixed on the fixture 6. Then, under the operation of the loading and unloading mechanism 5, it moves to the detection position. The detection mechanism 3 operates, so that the camera 7 collects images of the circuit board for appearance inspection. The laser rangefinder 8 is used to position and adjust the circuit board and detect the distance between each point and the detection head 10. Then, the electric push rod 9 extends and retracts, and moves in conjunction with the detection mechanism 3, so that the detection head 10 can perform multi-point detection on the circuit board. Because multiple workstation slots 4 are set, loading and unloading can be carried out continuously, improving detection efficiency.
[0027] Each of the fixtures 6 is connected to an air pipe, and each of the air pipes is connected to a vacuum pump.
[0028] The fixture 6 includes a fixing plate 601, on which a plurality of limiting blocks 602 are installed. The fixing plate 601 has a plurality of adsorption holes 603, each adsorption hole 603 is connected to a branch pipe, and all the branch pipes are connected to an air tube.
[0029] In practice, multiple limiting blocks 602 cooperate with the AR glasses circuit board to block and limit the edge of the circuit board. Each adsorption hole 603 is opened on the flat part of the bottom of the circuit board. When the vacuum pump is running, the air pipe is used to expel the air between each adsorption hole 603 and the circuit board, so that the circuit board can be adsorbed and fixed. This facilitates the operation of the loading and unloading mechanism 5, ensures the stable movement of the circuit board, improves the loading accuracy, and improves the loading efficiency and detection accuracy.
[0030] The detection mechanism 3 includes a first moving module 301, a crossbeam 302, a second moving module 303, and a moving base 304. There are two first moving modules 301, which are installed in parallel at the top of the inside of the detection chamber 2. The two first moving modules 301 are connected to the crossbeam 302. The second moving module 303 is installed on the crossbeam 302, and the moving base 304 is installed on the second moving module 303.
[0031] The bottom of the movable base 304 is equipped with an electric push rod 9, and the detection head 10 is installed at the end of the electric push rod 9. A laser rangefinder 8 and a camera 7 are provided on one side of the electric push rod 9.
[0032] In practice, the operation of two first moving modules 301 enables the crossbeam 302 to move back and forth, while the second moving module 303 controls the moving seat 304 to move left and right, thereby enabling the electric push rod 9, camera 7, and laser rangefinder 8 to move in the plane. The electric push rod 9 can control the detection head 10 to rise and fall, so that the detection head 10 can be adjusted arbitrarily in three-dimensional space to facilitate the detection of points at different locations on the circuit board.
[0033] The loading and unloading mechanism 5 includes a base 501, a motor 502, a lead screw 503, a slide rail 504, and a slide block 505. The base 501 is installed in the work station slot 4. The motor 502 is installed at one end of the base 501. The output end of the motor 502 is connected to the lead screw 503. Slide rails 504 are provided on both sides of the lead screw 503. The slide block 505 is sleeved on the lead screw 503 and is slidably connected to the two slide rails 504. A fixture 6 is installed on the slide block 505.
[0034] In practice, the motor 502 operates, causing the lead screw 503 to drive the slide 505 to move along the two slide rails 504, thereby driving the fixture 6 to move to the entrance of the testing chamber 2 for loading and unloading. When the fixture 6 moves into the testing chamber 2, it can automatically load materials for circuit board testing.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
