Technical Field

[0001] This utility model relates to the field of prism assembly detection technology, specifically to an eccentricity detection component for a prism assembly. Background Technology

[0002] The prism assembly includes a prism base, a roof prism, a light-blocking plate, a semi-pentagonal prism, and a retaining ring. The retaining ring and the prism base are each provided with screw holes, and the two are fixed together by mortise screws.

[0003] In the existing technology, after the prism assembly and glue application are completed, technicians are generally required to perform eccentricity testing. However, this testing method has the following drawbacks: low testing efficiency and long-term light exposure can easily cause eye fatigue. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an eccentricity detection component for a prism assembly.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An eccentricity detection component for a prism assembly includes:

[0007] The hollow cover has a first support plate inside, which can divide the inner cavity of the hollow cover into an upper cavity and a lower cavity.

[0008] The second support plate is located in the lower cavity and is rotatably equipped with a jig platform. The top of the jig platform is coaxially provided with a material trough for placing the prism assembly.

[0009] The light source is disposed within the lower cavity;

[0010] A support base is provided on the front side of the light source. A cross reticle and a right-angle prism are arranged sequentially along the direction of the light emitted from the light source. A first light-transmitting hole facing the right-angle prism is opened on the top of the support base. A second light-transmitting hole aligned with the first light-transmitting hole is opened coaxially on the fixture table. The top of the second light-transmitting hole penetrates the bottom wall of the material tank.

[0011] A graduated glass plate is disposed on the first support plate and has three parallel graduated lines.

[0012] A camera is located in the upper cavity, with its lens facing the graduated glass plate.

[0013] Preferred options also include:

[0014] A photoelectric sensor, mounted on the second support plate, is used to monitor whether a prism assembly is placed in the trough;

[0015] The information processor is electrically connected to the photoelectric actuator, and the light source is electrically connected to an external power source through the information processor.

[0016] Preferred options also include:

[0017] A stepper motor is located at the bottom of the second support plate;

[0018] A rotating hollow platform is mounted on the second support plate, with one end connected to the stepper motor and the other end coaxially connected to the fixture table.

[0019] Preferred options also include:

[0020] A miniature photoelectric switch is mounted on the second support plate and is electrically connected to the information processor.

[0021] The sensing element extends outward from the side of the fixture platform. When the fixture platform rotates, the sensing element can pass through the miniature photoelectric switch.

[0022] Preferred options also include:

[0023] A suspension bracket is mounted on the first support plate, and its top end is fixedly connected to the camera.

[0024] Preferably, the first support plate has a notch for mounting the scale glass plate, and the scale glass plate is fixedly connected to the notch by adhesive.

[0025] Preferred options also include:

[0026] A reflective lens, disposed in the lower cavity, is capable of reflecting light passing through the fixture stage onto the graduated glass plate.

[0027] Preferred options also include:

[0028] The mounting plate has a mounting surface for mounting the reflective lens and is movably connected to the cavity wall of the lower cavity.

[0029] The locking structure acts on the mounting plate and can restrict the mounting plate from flipping relative to the cavity wall of the lower cavity.

[0030] Preferably, the mounting plate is provided in two parts, and the reflective lens includes:

[0031] The first lens is inclinedly disposed in the lower cavity via one of its mounting plates;

[0032] The second lens is laid flat on the cavity wall of the lower cavity in the vertical direction;

[0033] The third lens is obliquely disposed in the lower cavity via another mounting plate, and the second lens faces the first and second lenses.

[0034] Preferred options also include:

[0035] Two rotating shafts, and the two mounting plates are respectively rotatably disposed in the lower cavity via the rotating shafts;

[0036] Two arc-shaped adjustment slots are provided on the side wall of the lower cavity. The locking structure includes a screw and a nut. The mounting plate has a through hole at the end away from the rotating shaft. The screw passes through the through hole and the arc-shaped adjustment slot in sequence and then engages with the nut through a thread.

[0037] The beneficial effects of this invention are as follows: During operation, the prism assembly to be tested is first placed in the material trough of the fixture table. When the light emitted by the light source passes through the cross reticle, a cross ray is generated. The cross ray is reflected by the right-angle prism to the bottom wall of the material trough. The reflected cross ray passes through the prism assembly to be tested and illuminates the scale glass plate. The camera takes a picture of the cross ray illuminating the scale glass plate. If the cross ray exceeds the range of the three parallel scale lines, the prism assembly is defective; otherwise, it is good. Compared with the prior art, using a camera to take a picture of the light and the three parallel scale lines to determine whether the prism assembly has an eccentric problem reduces the influence of light on the technician during the testing process and helps to improve production efficiency.

[0078] Preferred options also include:

[0079] Two rotating shafts, and two mounting plates 44 are respectively rotatably disposed in the lower cavity 13 via the rotating shafts;
