Description

Technical Field

[0001] This invention belongs to the field of detection device technology, specifically a cover plate warping deformation detection device. Background Technology

[0002] Cover plate warping refers to the unevenness of the surface of an object after heat treatment, cutting, or other processes, caused by external factors. Excessive warping may lead to incomplete bonding and product damage. Therefore, warping testing is required for the produced cover plates.

[0003] The warpage of the cover plate is usually measured using a laser measuring instrument. The non-contact laser sampling method does not damage the workpiece. When measuring the warpage of the cover plate, a laser probe is used to measure both the upper and lower surfaces of the glass simultaneously. The thickness, thickness variation, and warpage are evaluated through data processing.

[0004] When testing the warpage of a glass cover, a laser is emitted from the testing equipment and projected onto the glass cover to complete the test. However, the laser beam hitting the glass cover is prone to scattering, and the reflected laser beam can also be inaccurate, leading to deviations in the test results.

[0005] To address this, the present invention provides a cover plate warping deformation detection device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] Furthermore, an arc-shaped connecting rod is fixedly installed on one side of the sliding block, the end of the connecting rod is spherical, and several iron plates of different lengths are installed on the side of the connecting block near the connecting rod and are rotatably connected by torsion springs.

[0009] Furthermore, one end of the sliding block is provided with a rounded corner, and the arc-shaped surface of the cam abuts against the rounded corner of the sliding block.

[0010] Furthermore, the auxiliary component includes a shim fixedly mounted on the top of the cam, a friction pad fixedly mounted on the bottom of the cam, and a sponge pad coated with pigment fixedly mounted inside the friction pad.

[0011] Furthermore, the air blowing mechanism includes a base fixedly installed on the top of the connecting frame. Four arc-shaped extrusion plates are slidably connected to the top of the base by springs. Hollow elastic balls are fixedly installed at the bottom of the connecting plates. An air guide tube connected to the inside is fixedly installed on the top of the elastic balls. Several inclined air outlet tubes are fixedly installed at the bottom of the connecting frame. One end of the air guide tube is connected to the air outlet tube.

[0012] Furthermore, it also includes an end cap that is rotatably connected to the air outlet pipe via a torsion spring, wherein a semi-circular limiting rod is fixedly installed on the outer surface of the air outlet pipe; and an extension component for extending the gas blowing out is provided inside the air outlet pipe.

[0013] Furthermore, the extension assembly includes a baffle fixedly installed inside the air outlet pipe, one end of the baffle being conical, and an extension tube being slidably connected to the inside of the air outlet pipe via an elastic rope, with an air vent groove of a size adapted to the baffle at one end of the extension tube near the baffle.

[0014] Furthermore, the pushing component includes a fixed plate that is fixedly installed at the bottom of the connecting frame and abuts against the cam, a metal push plate is fixedly installed at the bottom of the cam, and slots are provided on both sides of the conveyor.

[0015] Furthermore, the end of the push plate away from the cam is arc-shaped, and several rubber convex balls are fixedly installed on the arc-shaped surface of the cam.

[0016] The beneficial effects of this invention are as follows: 1. This invention utilizes a laser detection probe that strikes a gasket. Because this method minimizes scattering and deviation, the laser beam is more reliable than when it strikes the glass cover. Furthermore, if the glass cover is not warped, the cam will not rotate, indicating that the glass cover meets manufacturing requirements. This dual detection system provides better results. Since the laser detection probe can only detect the area directly below, the multiple cams designed in this invention can directly detect areas not illuminated by the laser, thus improving detection efficiency. This eliminates the need for the laser detection probe to reciprocate over the glass cover, resulting in higher accuracy. If the glass cover warps, the movement of the cams via the connecting frame causes the friction pad at the bottom of the cam to contact the glass cover. The friction pad increases friction, causing the cam to rotate counterclockwise. During rotation, the cam compresses the friction pad, causing the paint-soaked sponge pad inside the friction pad to contact the glass cover. This paint marks the warped area, facilitating subsequent analysis of the warped area and targeted improvements. As the cam rotates, it pushes the sliding block on the connecting block, causing the sliding block to slide away from the cam. This causes the ball end of the connecting rod on the sliding block to continuously strike the iron plate, making a sound to indicate that the glass cover is warped. Because the bottom of the cam is arc-shaped and one end of the sliding block has a rounded corner, it can better cooperate to lift the sliding block.

[0017] 2. In this invention, when the glass cover plate moves to the bottom of the detection section to await detection, the electric push rod first moves the base and the extrusion plate towards the elastic ball. The base and the arc-shaped extrusion plate extrude pressure on the elastic ball. As the extrusion plate contacts the connecting plate, the base continues to move towards the connecting plate, causing the extrusion plate to slide downwards within the base. This facilitates complete extrusion of the elastic ball by the base, allowing the gas inside the elastic ball to enter the outlet pipe through the vent pipe. After entering the outlet pipe, the gas is guided to the extension pipe by the conical baffle, which then pushes the extension pipe to slide away from the outlet pipe, thereby opening the end cover. This causes one side of the end cover to be in contact with the limiting rod and tilted. Since one end of the extension pipe is no longer in contact with the baffle, the venting groove at one end of the extension pipe is exposed. The gas in the outlet pipe enters the extension pipe through the venting groove and is sprayed onto the conveyor belt and the glass cover plate, thereby reducing dust and impurities on the surface of the glass cover plate and avoiding affecting the subsequent cam detection of the glass cover plate. The extension pipe compensates for the fact that the outlet pipe moves away from the surface of the glass cover plate due to the rise of the electric push rod. When the electric push rod moves down, the elastic ball is no longer squeezed by the base. At this time, the extension tube is reset into the air outlet tube by the action of the elastic rope, so as not to affect the subsequent testing work. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 10As shown, the cover plate warping deformation detection device of the present invention includes a detection machine 1. A detection part 2 is installed on the top of the detection machine 1. A laser detection probe is fixedly installed on the bottom of the detection part 2. A conveyor 3 passing through itself is installed on one side of the detection machine 1. A glass cover plate 4 is placed on the conveyor belt of the conveyor 3. A connecting plate 5 is fixedly installed on one side of the detection part 2. An electric push rod 6 is fixedly installed on the bottom of the connecting plate 5. A connecting frame 7 is fixedly installed at the output end of the electric push rod 6. A plurality of cams 8 are rotatably connected to the connecting frame 7 through a round shaft. The cams 8 are located directly below the laser detection probe. A plurality of connecting blocks 9 corresponding one-to-one with the cams 8 are fixedly installed inside the connecting frame 7. An inclined sliding block 10 is slidably connected to one side of the connecting block 9. One end of the sliding block 10 is in contact with the cam 8.

[0023] Specifically, an arc-shaped connecting rod 11 is fixedly installed on one side of the sliding block 10. The end of the connecting rod 11 is spherical. Several iron pieces 12 of different lengths are installed on the side of the connecting block 9 near the connecting rod 11 and are rotatably connected by torsion springs. One end of the sliding block 10 is provided with a rounded corner 13, and the arc-shaped surface of the cam 8 abuts against the rounded corner 13 of the sliding block 10.

[0024] The surface of the cam 8 is provided with an auxiliary component 20 for the auxiliary inspection machine 1 to inspect the glass cover plate 4. The auxiliary component 20 includes a pad 21 fixedly installed on the top of the cam 8, a friction pad 22 fixedly installed on the bottom of the cam 8, and a sponge pad 23 coated with pigment fixedly installed inside the friction pad 22.

[0025] During operation, the detection unit 2, along with the connecting plate 5 and the electric push rod 6, moves to the right side of the conveyor 3, bringing the detection unit 2 to its initial position. Then, the glass cover plate 4 to be tested is placed on the conveyor belt of the conveyor 3, and the conveyor belt moves the glass cover plate 4 to below the laser detection probe of the detection unit 2. The height of the connecting frame 7 and the cam 8 is then adjusted by the electric push rod 6, so that the top surface of the glass cover plate 4 and the bottom surface of the cam 8 are in contact. At this time, the laser detection probe of the detection unit 2 emits a laser beam that shines on the pad 21 of the cam 8. Simultaneously, the detection unit 2 drives the connecting plate 5 and other components to move towards the glass cover plate 4, thus completing the detection from right to left. The laser emitted by the laser detection probe, when hitting the pad 21, has higher reliability due to less scattering and smaller deviation compared to hitting the glass cover 4. Furthermore, if the glass cover 4 is not warped, the cam 8 will not rotate, indicating that the glass cover 4 meets manufacturing requirements. This dual detection system achieves better results. Since the laser detection probe can only detect the area directly below, the multiple cams 8 designed in this invention can directly detect areas not illuminated by the laser, thus improving detection efficiency. This eliminates the need for the laser detection probe to reciprocate over the glass cover 4, resulting in higher accuracy. If the glass cover 4 warps, the connecting frame 7 moves the cam 8, causing the friction pad 22 at the bottom of the cam 8 to contact the glass cover 4. The friction pad 22 increases friction, causing the cam 8 to rotate counterclockwise. During rotation, the cam 8 compresses the friction pad 22, causing the paint-soaked sponge pad 23 inside the friction pad 22 to contact the glass cover. This marks the warped area of ​​the glass cover 4 with paint, facilitating subsequent analysis of the warped area and targeted improvements. As the cam 8 rotates, it pushes the sliding block 10 on the connecting block 9, causing the sliding block 10 to slide away from the cam 8. This causes the ball end of the connecting rod 11 on the sliding block 10 to continuously strike the iron plate 12, making a sound to indicate that the glass cover 4 is warped. Since the bottom of the cam 8 is arc-shaped and one end of the sliding block 10 has a rounded corner 13, it can better cooperate to lift the sliding block 10. After the cam 8 has finished detecting the glass cover 4, the cam 8 no longer contacts the glass cover 4 and slowly rotates to reset.

[0026] In one embodiment of the present invention, the top of the connecting frame 7 has an air blowing mechanism 30 for cleaning the surface of the conveyor 3. The air blowing mechanism 30 includes a base 31 fixedly installed on the top of the connecting frame 7. The top of the base 31 is slidably connected to four arc-shaped extrusion plates 32 by springs. The bottom of the connecting plate 5 is fixedly installed with a hollow elastic ball 33. The top of the elastic ball 33 is fixedly installed with an air guide pipe 34 that communicates with the interior. The bottom of the connecting frame 7 is fixedly installed with a plurality of inclined air outlet pipes 35. One end of the air guide pipe 34 is connected to the air outlet pipe 35. The connecting frame 7 also includes an end cap 36 that is rotatably connected to the air outlet pipe 35 by a torsion spring. The outer surface of the air outlet pipe 35 is fixedly installed with a semi-circular limiting rod 37.

[0027] Specifically, the interior of the air outlet pipe 35 is provided with an extension component 351 that extends the gas blowing out. The extension component 351 includes a baffle 353 that is fixedly installed inside the air outlet pipe 35. One end of the baffle 353 is conical. The interior of the air outlet pipe 35 is slidably connected to an extension pipe 352 by an elastic rope. The end of the extension pipe 352 near the baffle 353 is provided with a ventilation groove 354 that is adapted to the size of the baffle 353.

[0028] During operation, when the glass cover plate 4 moves below the detection section 2 to await detection, the electric push rod 6 first moves the base 31 and the compression plate 32 towards the elastic ball 33. The base 31 and the arc-shaped compression plate 32 compress the elastic ball 33. As the compression plate 32 contacts the connecting plate 5, the base 31 continues to move towards the connecting plate 5, causing the compression plate 32 to slide downwards within the base 31. This facilitates the base 31 to completely compress the elastic ball 33, allowing the gas inside the elastic ball 33 to enter the outlet pipe 35 through the gas guide pipe 34. After entering the outlet pipe 35, the gas is guided by the conical baffle 353 to the extension pipe 352, thereby pushing the extension... The extension tube 352 slides away from the vent tube 35, thereby opening the end cover 36. This causes one side of the end cover 36 to come into contact with the limiting rod 37 and become inclined. Since one end of the extension tube 352 is no longer in contact with the baffle 353, the vent groove 354 at one end of the extension tube 352 is exposed. The gas in the vent tube 35 enters the extension tube 352 through the vent groove 354 and is sprayed onto the conveyor belt and the glass cover plate 4, thereby reducing dust and impurities on the surface of the glass cover plate 4 and avoiding affecting the subsequent detection of the glass cover plate 4 by the cam 8. The extension tube 352 compensates for the vent tube 35 moving away from the surface of the glass cover plate 4 due to the rise of the electric push rod 6. When the electric push rod 6 moves down, the elastic ball 33 is no longer squeezed by the base 31. At this time, the extension tube 352 returns to its original position in the vent tube 35 under the action of the elastic rope, thus not affecting the subsequent detection work.

[0029] In one embodiment of the present invention, a pushing assembly 40 for pushing the glass cover plate 4 is installed at the bottom of the cam 8. The pushing assembly 40 includes a fixed plate 41 fixedly installed at the bottom of the connecting frame 7 and abutting against the cam 8. A push plate 42 is fixedly installed at the bottom of the cam 8. Slots 44 are provided on both sides of the conveyor 3. The end of the push plate 42 away from the cam 8 is arc-shaped. A plurality of rubber convex balls 43 are fixedly installed on the arc-shaped surface of the cam 8.

[0030] During operation, after cam 8 completes its inspection of glass cover 4 from right to left, and if glass cover 4 is warped, cam 8 is positioned to the left of glass cover 4. As the inspection unit 2 moves cam 8 to its initial position to the right, the push plate 42 at the bottom of cam 8 contacts the warped area of ​​glass cover 4. At this point, the fixing plate 41 holds cam 8 in place, preventing it from rotating clockwise. The rubber protrusions 43 on the push plate 42 increase friction with the warped area of ​​glass cover 4, thus pushing the warped glass cover 4 out of the slot 44 onto the conveyor 3. This process sorts the inspected covers. Covers that pass inspection, lacking warping deformation, do not contact the protrusions 43 and continue to the next process via the conveyor belt. The push plate 42 is made of metal to increase weight, allowing cam 8 to accelerate its reset after detecting warped rotation of glass cover 4 with counterweight.

[0031] Working principle: First, the detection unit 2, along with the connecting plate 5 and the electric push rod 6, moves to the right side of the conveyor 3, bringing the detection unit 2 to its initial position. Then, the glass cover plate 4 to be tested is placed on the conveyor belt of the conveyor 3, and the conveyor belt moves the glass cover plate 4 to below the laser detection probe of the detection unit 2. The electric push rod 6 then moves the base 31 and the extrusion plate 32 towards the elastic ball 33. The base 31 and the arc-shaped extrusion plate 32 extrude pressure on the elastic ball 33. As the extrusion plate 32 contacts the connecting plate 5, the base 31 continues to move towards the connecting plate 5, causing the extrusion plate 32 to slide downwards within the base 31. This facilitates the base 31 to completely extrude pressure on the elastic ball 33, allowing the gas inside the elastic ball 33 to enter the exhaust pipe 35 through the gas guide pipe 34. Inside, when gas enters the vent pipe 35, it is guided by the conical baffle 353 to the extension pipe 352, which in turn pushes the extension pipe 352 to slide away from the vent pipe 35, thereby opening the end cover 36. This causes one side of the end cover 36 to be in contact with the limiting rod 37 and to be inclined. Since one end of the extension pipe 352 is no longer in contact with the baffle 353, the ventilation groove 354 at one end of the extension pipe 352 is exposed. The gas in the vent pipe 35 enters the extension pipe 352 through the ventilation groove 354 and is sprayed onto the conveyor belt and the glass cover plate 4, thereby reducing dust and impurities on the surface of the glass cover plate 4 and avoiding affecting the subsequent detection of the glass cover plate 4 by the cam 8. The extension pipe 352 is used to compensate for the fact that the vent pipe 35 is away from the surface of the glass cover plate 4 due to the rise of the electric push rod 6. When the electric push rod 6 moves down, the elastic ball 33 is no longer squeezed by the base 31. At this time, the extension tube 352 is reset into the air outlet tube 35 under the action of the elastic rope, so as not to affect the subsequent testing work.

[0032] Next, the height of the connecting frame 7 and the cam 8 is adjusted by the electric push rod 6, so that the top surface of the glass cover plate 4 and the bottom surface of the cam 8 are in contact. At this time, the laser detection probe of the detection unit 2 emits a laser beam that shines on the pad 21 of the cam 8. Simultaneously, the detection unit 2 drives the connecting plate 5 and other components to move towards the glass cover plate 4, thus completing the inspection from right to left. If the glass cover plate 4 is not warped, the cam 8 will not rotate, which proves that the glass cover plate 4 meets the manufacturing requirements. If the glass cover plate 4 is warped, as the connecting frame 7 moves the cam 8, the friction pad 22 at the bottom of the cam 8 will come into contact with the glass cover plate 4. The friction pad 22 increases friction, thereby driving the cam 8 to rotate counterclockwise. When the cam 8 rotates, it will squeeze the friction pad 22, causing the sponge pad 23 filled with paint inside the friction pad 22 to come into contact with the glass cover. This marks the warped area of ​​the glass cover plate 4 with paint, making it easier for subsequent staff to analyze the cause of the warping and make targeted improvements. As the cam 8 rotates, it pushes the sliding block 10 on the connecting block 9, causing the sliding block 10 to slide away from the cam 8. This causes the ball end of the connecting rod 11 on the sliding block 10 to continuously strike the iron plate 12, making a sound to indicate that the glass cover 4 is warped. Since the bottom of the cam 8 is arc-shaped and one end of the sliding block 10 has a rounded corner 13, it can better cooperate to lift the sliding block 10. After the cam 8 has finished detecting the glass cover 4, the cam 8 no longer contacts the glass cover 4 and slowly rotates to reset.

[0033] After the cam 8 completes the inspection of the glass cover plate 4 from right to left, and the glass cover plate 4 is warped, the cam 8 is located on the left side of the glass cover plate 4. As the inspection unit 2 moves the cam 8 to the right to the initial position, the push plate 42 at the bottom of the cam 8 will contact the warped part of the glass cover plate 4. At this time, the fixing plate 41 will hold the cam 8 in place, preventing the cam 8 from rotating clockwise. The rubber ball 43 on the push plate 42 will increase the friction with the warped part of the glass cover plate 4, thereby pushing the warped glass cover plate 4 out of the conveyor 3 through the slot 44.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
