Description

Technical Field

[0001] The utility model relates to the field of lens detection, in particular to a glass mirror detection device. Background Art

[0002] During the lens production process, some defects are inevitable, such as scratches, open bubbles, and pitting on the lens surface. To ensure the quality of the lenses before they leave the factory, lens defects need to be inspected after production. Existing lens inspection systems select defective products by capturing and photographing the lens images. To ensure accuracy during inspection, the lenses are usually placed in a test liquid that covers the lens surface. This allows light to be refracted less at the interface between the glass and the liquid, reducing visual errors caused by changes in the refraction angle when observed by the human eye or detected by instruments, thereby improving the accuracy and reliability of calibration. Currently, after completing the inspection of multiple lenses, in order to ensure the accuracy of the next batch of lenses, the test liquid in the placement plate used to place the lenses needs to be cleaned. Currently, the placement plate is usually manually removed for cleaning and replaced with a new one for the next batch of inspections, which makes the overall efficiency low. To this end, we designed a glass mirror inspection device. Utility Model Content

[0003] In order to solve the technical problem of manually removing a placement plate for cleaning and replacing it with a new placement plate to carry out the inspection of the next batch, the utility model provides a glass mirror inspection device.

[0004] The utility model is implemented by the following technical solution: a glass mirror detection device, comprising a machine platform, a support frame is installed on the machine platform for forward and backward movement, a transverse movement module is installed on the front surface of the support frame, and a CCD camera is installed on the slider of the transverse movement module;

[0005] A mounting frame is suspended and fixed above the machine, and two lens storage fixtures are symmetrically installed on the front and rear sides of the mounting frame, wherein the lens storage fixture includes a flip plate, which is rotatably mounted on the mounting frame through a bracket, a bearing and an axle pin, and a placement plate is fixed above the flip plate, and a plurality of placement slots for placing lenses are opened above the placement plate, and the outward side of the flip plate is connected to the output shaft of the flip motor through an axle pin;

[0006] A liquid injection mechanism is installed on the right side above the mounting frame so as to move forward and backward. The liquid injection mechanism includes a horizontal plate that is arranged to move forward and backward. The horizontal plate is located above the placement plate and is equipped with a plurality of liquid injection droppers distributed at equal intervals.

[0007] The machine is provided with two lifting openings, and the two lifting openings are respectively located directly below the two flip plates. Two collection frames are installed in the two lifting openings in an up-and-down lifting manner. A heightening plate is installed in the collection frame, and a plurality of nozzles distributed at equal intervals are installed on the heightening plate.

[0008] As a further improvement of the above solution, a longitudinal moving module 1 and a guide rail are respectively installed on the left and right sides above the machine, and the left and right ends below the support frame are respectively connected to the sliders on the longitudinal moving module 1 and the guide rail. The longitudinal moving module 1 can enable the CCD camera to move back and forth left and right. In conjunction with the set transverse moving module, the CCD camera can move arbitrarily on the X / Y axis, and then can move to above any lens, thereby facilitating separate inspection of multiple lenses.

[0009] As a further improvement to the above solution, a second longitudinal moving module is installed on the right side above the mounting frame, and the transverse plate is installed on the slider of the second longitudinal moving module through a bracket. The number of injection droppers above the transverse plate matches the number of placement slots on the placement plate, and the lower ends of the injection droppers pass through the transverse plate and are located directly above the placement slots. The number of injection droppers is the same as the number of placement slots arranged transversely. The injection droppers can inject detection liquid into the placement slots, thereby facilitating subsequent accurate detection by the CCD camera.

[0010] The tops of the plurality of injection droppers are connected to the liquid outlet of an external peristaltic pump through a hose, and the peristaltic pump is connected to a jar filled with detection liquid through a hose, so that each placement slot can be filled with detection liquid.

[0011] As a further improvement of the above scheme, the number of the nozzles is exactly the same as the number of placement slots, and multiple nozzles are respectively located directly below multiple placement slots. Multiple nozzles can blow air on the inner walls of multiple placement slots at the same time, thereby blowing away the detection liquid attached to the inner walls, which is also convenient for the next detection.

[0012] As a further improvement to the above solution, a connecting pipe is welded to the bottom of the collection frame. The top of the connecting pipe is connected to the lower inlets of multiple nozzles through a hose, and the lower end of the connecting pipe is connected to the air outlet of an external air pump through a hose. The high-pressure airflow generated by the air pump can be distributed to each nozzle through the connecting pipe and the hose, thereby being able to clean and blow the inner walls of multiple placement tanks at the same time.

[0013] A liquid discharge port is also provided below the collection frame. A liquid discharge pipe and a valve are provided on the liquid discharge port to facilitate discharge of the detection liquid collected inside the collection frame.

[0014] As a further improvement of the above scheme, a lifting assembly is respectively installed under the two lifting ports, and the lifting assembly includes a hanging plate installed under the lifting port through a support rod, and a lifting cylinder is installed under the hanging plate. The push rod of the lifting cylinder passes through the hanging plate and is connected to the center of the bottom of the collection frame. A guide rod is respectively installed at the four corners of the lower surface of the collection frame, and the guide rod is slid up and down on the hanging plate. The collection frame can move up as a whole and make the nozzle close to the placement slot, which is convenient for cleaning and blowing.

[0016] 1.

The liquid injection mechanism 8 includes a horizontal plate 81 that is movable back and forth. The horizontal plate 81 is located above the placement plate 42 and has a plurality of liquid injection droppers 82 distributed at equal intervals installed on the horizontal plate 81.

[0033] A longitudinal moving module 23 and a guide rail 22 are respectively installed on the left and right sides above the machine 1. The left and right ends of the lower side of the support frame 21 are connected to the sliders on the longitudinal moving module 23 and the guide rail 22 respectively. The longitudinal moving module 23 can enable the CCD camera 3 to move back and forth left and right. In conjunction with the set transverse moving module 2, the CCD camera 3 can move arbitrarily on the X / Y axis, and can then be moved to above any lens, thereby facilitating separate inspection of multiple lenses.

[0034] A second longitudinal moving module 83 is installed on the right side above the mounting frame 6. The transverse plate 81 is mounted on the slider of the second longitudinal moving module 83 via a bracket. The number of injection droppers 82 above the transverse plate 81 matches the number of placement slots 421 on the placement plate 42. The lower ends of the injection droppers 82 pass through the transverse plate 81 and are located directly above the placement slots 421. The number of injection droppers 82 is the same as the number of placement slots 421 arranged transversely. The injection droppers 82 can inject detection liquid into the placement slots 421, thereby facilitating subsequent accurate detection by the CCD camera 3.

[0035] The tops of the multiple injection droppers 82 are connected to the liquid outlet of an external peristaltic pump through a hose. The peristaltic pump is connected to a tank filled with detection liquid through a hose, so that each placement slot 421 can be filled with detection liquid.

[0036] The number of nozzles 73 is exactly the same as the number of placement slots 421, and multiple nozzles 73 are respectively located directly below the multiple placement slots 421. Multiple nozzles 73 can blow air to the inner walls of multiple placement slots 421 at the same time, thereby blowing away the detection liquid attached to the inner walls, which is also convenient for the next detection.

The top of the connecting pipe 71 is connected to the lower inlets of multiple nozzles 73 via a hose, and the lower end of the connecting pipe 71 is connected to the air outlet of an external air pump via a hose. The high-pressure airflow generated by the air pump can be distributed to each nozzle 73 through the connecting pipe 71 and the hose, thereby simultaneously cleaning and blowing the inner walls of multiple placement slots 421.

[0038] A drain port is also provided below the collecting frame 7 , and a drain pipe and a valve are provided on the drain port to facilitate the discharge of the detection liquid collected inside the collecting frame 7 .

The collection frame 7 can be moved up as a whole and the nozzle 73 is close to the placement groove 421, which is convenient for cleaning and blowing.

[0040] The working principle of a glass mirror inspection device in the embodiment of the present application is as follows: a robot for grabbing lenses is set on the right side of the machine 1, and the robot places the sucked lenses into the placement groove 421 of the placement plate 42. After placement, the robot gives a signal, and the middle liquid injection mechanism 8 moves to the top of the placement groove 421 where the lenses are placed. After the peristaltic pump is started, the detection liquid is dripped into the placement groove 421 above the placement plate 42. After the liquid injection is completed, the CCD camera 3 above takes a picture of the lens placed in the placement groove 421 to select the defects of the product. After the inspection is completed, the robot takes away the lens that has passed the inspection. When all the lenses are taken out, the entire lens storage tool 4 will be turned 180 degrees under the action of the turning motor 5, so that the test liquid in the placement groove 421 is poured into the collection frame 7, and the lifting cylinder 93 in the lifting assembly 9 makes the mobile phone frame move upward as a whole, so that the nozzle 73 is close to the placement groove 421 on the placement plate 42. The high-pressure airflow generated by the air pump can be distributed to each nozzle 73 through the connecting pipe 71 and the hose, so that the inner walls of multiple placement grooves 421 can be cleaned and blown at the same time. After that, the lens storage tool 4 is rotated 180 degrees again to return to its original position and wait for the next test;

[0041] By arranging two sets of lens storage fixtures 4 above the machine 1 and setting a CCD camera 3 that can be moved arbitrarily on the X / Y axis, and then can be moved above any lens, it is convenient to perform separate inspections on multiple lenses, thereby improving the efficiency of visual inspection;

[0042] By designing the lens storage tooling 4 to rotate under the action of the flip motor 5, and coordinating with the collection frame 7 and multiple nozzles 73 matching the placement slot 421, the nozzles 73 in the collection frame 7 can approach the placement slot 421 under the action of the lifting component 9 and spray it with cleaning jets, which can quickly clean the detection liquid inside the placement slot 421, thereby facilitating the detection of the next batch of lenses and improving the detection efficiency.
