Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a laser testing device for the end curvature of a glass rod. Background Technology

[0002] After glass rods are manufactured, the accuracy of their end curvature directly affects their performance and lifespan. Glass rods with substandard end curvature may break or be damaged during use, posing safety hazards. Therefore, it is necessary to inspect the end curvature of glass rods. Laser measuring instruments are commonly used for this purpose. Laser inspection can ensure the accuracy of the end curvature test results. However, existing laser measuring instruments often only allow for the inspection of glass rods one by one, resulting in low inspection efficiency. Furthermore, clamps are required to hold and fix the glass rods during inspection to ensure stability and accuracy. However, different clamps are needed for glass rods of different diameters, making the operation cumbersome. The clamps are not adaptable to glass rods of different diameters within a certain range, which not only increases the workload of the workers but also affects the efficiency of glass rod inspection due to the frequent clamp changes. Summary of the Invention

[0003] The purpose of this invention is to provide a laser detection device for the end curvature of a glass rod, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A laser inspection device for the end curvature of a glass rod includes an inspection machine base, on which a control box and an inspection box are provided. The inspection box contains a rod positioning component, which positions the rod.

[0006] The testing box is equipped with a mobile laser testing mechanism, which tests the rod. The mobile laser testing mechanism is connected to a testing drive component, which moves the mobile laser testing mechanism.

[0007] The detection box is also equipped with a straightening drive assembly, which rotates through the detection drive assembly and is connected to a rod straightening mechanism.

[0008] The rod straightening mechanism straightens the rod, enabling the mobile laser detection mechanism to successfully detect the rod.

[0009] Preferably, the rod positioning component is a detection bearing cylinder;

[0010] The testing box is also symmetrically equipped with inner support bars, which support the straightening drive assembly and the rod straightening mechanism.

[0011] Preferably, the mobile testing mechanism is a testing support plate, which is installed in the testing box.

[0012] Preferably, a laser detector is fixedly installed on the detection support plate. When the rod is being detected, the laser detector moves above the detection support cylinder to detect the rod.

[0013] Preferably, the detection drive assembly includes a detection protective cover and a downward push rod, wherein the detection protective cover covers the detection box;

[0014] The protective cover pushes the downward push rod to move downwards, and the downward push rod drives the detection support plate to move.

[0015] Preferably, the straightening drive assembly is a rotating carrier plate, which is mounted on the inner support bar;

[0016] When the push rod moves downwards, it causes the rotating carrier plate to rotate.

[0017] Preferably, the rod straightening mechanism includes a supporting movable plate and a supporting clamp, wherein there are two supporting movable plates, which are installed opposite to each other on the inner supporting bar.

[0018] Preferably, the movable support plate close to the rotating carrier plate is connected to the rotating carrier plate, and the rotating carrier plate moves the movable support plate as it rotates.

[0019] Preferably, a connecting frame is provided between the two movable load-bearing plates, and the connecting frame is supported by an inner load-bearing strip.

[0020] Preferably, the relative and opposite movement between the two load-bearing movable plates is achieved by connecting the frame.

[0021] Preferably, a support clamp is installed on the supporting movable plate, and the support clamp clamps the rod to hold and straighten it.

[0022] Preferably, the support clamp can move relative to the supporting movable plate to accommodate rods of different diameters.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0024] 1. The testing chamber contains multiple testing support cylinders. When testing glass rods, they are inserted into the testing support cylinders, and then the testing protective cover is placed on the testing chamber. This automatically straightens the glass rods, placing them in a stable vertical position, making it easy for the laser detector to test them. No operator is required to operate the clamps, which is very convenient and quick. It can test multiple glass rods at the same time, thus improving the efficiency of glass rod testing to a certain extent.

[0025] 2. When the testing box is open, the laser detector is not directly above the testing support cylinder. This allows the operator to easily insert the glass rod into the testing support cylinder. When the protective cover is placed on the testing box, as the cover moves downward, it will drive the downward push rod downward, which in turn will move the testing support plate. As the testing support plate moves, the laser detector can be moved above the testing support cylinder, making it easier for the laser detector to test the glass rod.

[0026] 3. In addition, as the downward push rod moves down, it will drive the rotating carrier plate to rotate, which in turn will drive the adjacent carrier movable plate to move towards the glass rod, and then drive another carrier movable plate to move towards the glass rod as well. In this way, the glass rod can be straightened and clamped by the support clamp. Since the support clamp and the carrier movable plate are movable, it can adapt to glass rods of different diameters within a certain range for testing, which is very convenient.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides a technical solution:

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a laser inspection device for the end curvature of a glass rod includes an inspection platform 1, a control box 2 and an inspection box 3 on the inspection platform 1. The inspection box 3 contains a rod positioning component for positioning the rod. A mobile laser inspection mechanism is installed in the inspection box 3 to inspect the rod. The mobile laser inspection mechanism is connected to an inspection drive component for movement. A straightening drive component is also installed in the inspection box 3, rotating via the inspection drive component. The straightening drive component is connected to a rod straightening mechanism for straightening the rod, thus enabling the mobile laser inspection mechanism to smoothly inspect the rod.

[0041] like Figure 4 and Figure 5 As shown, the rod positioning component is a detection bearing cylinder 32. The inner diameter of the detection bearing cylinder 32 is larger than the diameter of the rod. Rubber protrusions 321 are symmetrically arranged inside the detection bearing cylinder 32. The rubber protrusions 321 can restrict the glass rod and prevent it from tilting in the direction of the rubber protrusions 321. The detection box 3 is also symmetrically arranged with inner bearing strips 36. The inner bearing strips 36 support the straightening drive component and the rod straightening mechanism. One end of the inner bearing strip 36 is provided with a mounting hole 37. The inner bearing strip 36 is also provided with a movable bearing groove 38. The inner wall of the movable bearing groove 38 is smooth and burr-free. In addition, a limit bearing rod 39 is fixedly installed on the inner bearing strip 36.

[0042] like Figure 2 , Figure 4 and Figure 6 As shown, the mobile testing mechanism is a testing support plate 4, which is installed in the testing box 3. A laser detector 41 is fixedly installed on the testing support plate 4. When testing the rod, the laser detector 41 moves above the testing support cylinder 32 to test the rod. The testing box 3 is symmetrically fixedly provided with supporting movable support rods 33, which support the testing support plate 4. The testing support plate 4 is symmetrically provided with movable support holes 42, which cooperate with the supporting movable support rods 33. The testing support plate 4 is also symmetrically fixedly provided with a cooperating frame 43, and a first cooperating rod 44 is hinged on the cooperating frame 43.

[0043] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the inside of the test box 3 is also symmetrically fixed with a support and mating inner plate 34, and a support guide hole 35 is provided on the support and mating inner plate 34;

[0044] The detection drive assembly includes a detection protective cover 31 and a downward push rod 5. The detection protective cover 31 covers the detection box 3. The detection protective cover 31 pushes the downward push rod 5 downward, which in turn moves the detection support plate 4. Connecting support blocks 51 are symmetrically fixed at both ends of the downward push rod 5. Mounting support rods 52 are fixedly mounted on the connecting support blocks 51. The mounting support rods 52 are inserted into the support guide holes 35. A mating top plate 53 is fixedly mounted on the upper end of the mounting support rods 52, and a return spring 54 is sleeved on the mounting support rods 52. The return spring 54 is located on the upper side of the supporting mating inner plate 34. The connecting support blocks 51 are hinged to the lower end of the first mating rod 44.

[0045] like Figure 3 , Figure 7 and Figure 8 As shown, the straightening drive assembly is a rotating carrier plate 6, which is installed on the inner bearing bar 36. When the downward push rod 5 moves downward, it drives the rotating carrier plate 6 to rotate. A counterweight rotating bar 61 is symmetrically fixed on the rotating carrier plate 6, and a linkage insert 62 is fixed on the counterweight rotating bar 61. A rotating bearing rod 63 is also symmetrically fixed on the rotating carrier plate 6. A matching bearing 64 is sleeved on the rotating bearing rod 63, and the matching bearing 64 is assembled in the mounting hole 37.

[0046] like Figure 8 and Figure 9 As shown, the rod straightening mechanism includes a bearing movable plate 7 and a support clamping plate 8. There are two bearing movable plates 7, which are installed opposite each other on the inner bearing bar 36.

[0047] like Figure 9 and Figure 10 As shown, the movable support plate 7 near the rotating carrier plate 6 is connected to the rotating carrier plate 6. When the rotating carrier plate 6 rotates, it drives the movable support plate 7 to move. In addition, a lower extension drive plate 79 is fixedly provided at the lower end of the movable support plate 7 near the rotating carrier plate 6. A connecting channel 791 is symmetrically opened on the lower extension drive plate 79. A linkage pin 62 is inserted into the connecting channel 791. The inner wall of the connecting channel 791 is smooth and burr-free. The linkage pin 62 is in contact with the inner wall of the connecting channel 791.

[0048] like Figure 8 , Figure 9 and Figure 10 As shown, a connecting frame 77 connects the two movable bearing plates 7. The connecting frame 77 enables relative and opposite movement between the two movable bearing plates 7. Connecting protrusions 75 are symmetrically fixed at both ends of the movable bearing plates 7. A second mating rod 76 is hinged to the connecting protrusion 75. The other end of the second mating rod 76 is hinged to the connecting frame 77. The connecting frame 77 has a movable bearing hole 78, and a limit bearing rod 39 is inserted into the movable bearing hole 78.

[0049] like Figure 9 and Figure 10 As shown, a support clamp 8 is installed on the movable support plate 7. The support clamp 8 clamps and straightens the rod. The support clamp 8 can move relative to the movable support plate 7 to accommodate rods of different diameters. A sealing cavity 71 is provided on the movable support plate 7. A guide frame 72 is fixedly installed on the movable support plate 7 next to the sealing cavity 71. A loading through hole 73 and a movable insert 74 are symmetrically arranged on the movable support plate 7. The movable insert 74 is inserted into the movable support groove 38. A rubber pad 81 is attached to the support clamp 8. Symmetrically fixed supports are provided on the support clamp 8. There is a movable support rod 82, which is inserted into the loading through hole 73. A mating block 83 is fixedly installed on the movable support rod 82. A third mating rod 84 is hinged to the mating block 83. A reset support plate 85 is hinged to the other end of the third mating rod 84. A guide support plate 86 is fixedly installed on the reset support plate 85. The guide support plate 86 is inserted into the guide frame 72. A bearing insert rod 87 is also fixedly installed on the reset support plate 85. A sealing plug plate 88 is fixedly installed on the bearing insert rod 87. The sealing plug plate 88 is inserted into the sealing cavity 71.

[0050] Multiple testing support cylinders 32 are installed in the testing box 3, which can simultaneously test the end curvature of multiple glass rods. When testing a glass rod, it is inserted into the testing support cylinder 32, which limits its movement. Since the diameter of the testing support cylinder 32 is larger than the diameter of the glass rod, the glass rod will be tilted when placed inside. After placing the glass rod, the testing protective cover 31 is placed on the testing box 3. As the testing protective cover 31 is placed, it will come into contact with the mating top plate 53. Under the weight of the testing protective cover 31, the mating top plate 53 will move downwards. As the mating top plate 53 moves downwards, the return spring 54 will be compressed, and the return spring 54 will also be compressed. The movable connecting support block 51 moves downward. As the connecting support block 51 moves downward, it will drive the first mating rod 44 to move and rotate. Under the action of the first mating rod 44, the detection support plate 4 will move, thereby causing the detection support plate 4 to move the laser detector 41 above the detection support cylinder 32. This facilitates the laser detector 41 to detect the glass rod. When the detection protective cover 31 is not covering the detection box 3, the detection support plate 4 is located to the side of the detection support cylinder 32. This way, the detection support plate 4 will not obstruct the placement of the glass rod, making it convenient for the staff to place the glass rod into the detection support cylinder 32. In addition, as the connecting support block 51 moves downward, the downward pushing rod 5 will come into contact with the rotating support plate 6, thus, during the downward movement... The push rod 5 will cause the rotating carrier plate 6 to rotate, causing the counterweight rotating bar 61 on the rotating carrier plate 6 to rotate upward. As the counterweight rotating bar 61 rotates upward, the linkage pin 62 and the connecting channel 791 will cause the supporting movable plate 7 near the rotating carrier plate 6 to move towards the glass rod. In this way, under the action of the second cooperating rod 76, the connecting frame 77 will move away from the inner supporting bar 36. As the connecting frame 77 moves, under the action of the second cooperating rod 76, the other supporting movable plate 7 will also move towards the glass rod. This will cause the supporting clamp 8 on the supporting movable plate 7 to come into contact with the glass rod. Under the action of the supporting clamp 8, the glass rod can be pushed to move, so that the glass rod is positioned... In a vertical position, the detection end face of the glass rod faces the laser detector 41. Furthermore, the supporting movable plate 7 and the supporting clamp 8 are movably connected, allowing the supporting clamp 8 to accommodate glass rods of different diameters within a certain range when clamping and straightening the glass rod. During the straightening process, the distance between the supporting clamp 8 and the supporting movable plate 7 decreases due to the constraint of the glass rod. Conversely, when the distance between the supporting movable plate 7 and the supporting clamp 8 decreases, the distance between the connecting block 83 and the supporting movable plate 7 increases. This, under the action of the third cooperating rod 84, pulls the reset plate 85 to move, causing the sealing plug 88 on the reset plate 85 to move outwards from the sealing cavity 71.However, it will not move out of the sealing cavity 71. Thus, as the sealing plug plate 88 moves, a negative pressure will be formed in the sealing cavity 71. Under the action of this negative pressure, a pulling force will be generated on the sealing plug plate 88, which will allow the supporting movable plate 7 to clamp and support the glass rod, keeping it in a vertical position. The rubber pad 81 on the supporting clamp plate 8 can provide some protection for the glass rod during the clamping process. Additionally, during the straightening process, the rubber protrusion 321 can prevent the glass rod from tilting in the direction of the rubber protrusion 321. After the protective cover 31 is in place, the glass rod can be inspected. The inspection is then completed. Afterwards, the protective cover 31 is removed. As the protective cover 31 is removed, the reset spring 54 will cause the mating top plate 53 to move upward. As the mating top plate 53 moves upward, it will also cause the connecting bearing block 51 to move upward. Thus, under the action of the first mating rod 44, the detection bearing plate 4 will move, so that it is no longer above the detection bearing cylinder 32. This makes it easier for the staff to remove the glass rod. In addition, as the connecting bearing block 51 moves upward, the downward pushing rod 5 moves upward along with it. This allows the rotating plate 6 to be freed from the restriction of the downward pushing rod 5, so that the counterweight rotating bar 6 can rotate. 1. Under the influence of gravity, the rotating plate 6 rotates downwards, causing it to reset. As the counterweight rotating bar 61 rotates downwards, the linkage pin 62 and the connecting channel 791 cause the supporting movable plate 7 near the rotating plate 6 to move towards the rotating plate 6. As it moves towards the rotating plate 6, the connecting frame 77, under the action of the second cooperating rod 76, will move under the action of the connecting frame 77 towards the inner supporting bar 36. In this way, the other supporting movable plate 7 can be reset and moved under the action of the connecting frame 77, preparing for the next operation. In addition, as the supporting movable plate 7 resets and moves, the glass rod is removed. Under negative pressure, the sealing plug plate 88 will be reset, which in turn will reset the reset carrier plate 85. The reset carrier plate 85, in turn, will reset the support clamp plate 8 under the action of the third mating rod 84. The operation is simple and convenient, requiring no operator intervention. Operators simply place the glass rod in the testing carrier cylinder 32 and cover it with the testing protective cover 31 to adjust the glass rod, ensuring smooth testing. The simultaneous testing of multiple glass rods and the convenient adjustment of the glass rods greatly improve the efficiency of glass rod end curvature testing.
