Description

Technical Field

[0001] This utility model relates to the field of glass stress detection technology, and specifically to a glass surface stress detection device. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides. [1] The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc., and the main components are silicate complex salts. It is an amorphous solid with an irregular structure. It is widely used in buildings to insulate against wind and allow light to pass through. It is a mixture. There are also colored glasses that have been mixed with certain metal oxides or salts and have shown color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called organic glass. The stress state of glass after annealing is a reflection of the quality of the glass sample. We usually use a stress tester to test the stress of the glass.

[0003] A glass surface stress testing device disclosed in publication number CN212236571U includes a detector body with a measurement platform mounted on its upper surface. Under the operation of an air pump, dust from the glass surface is drawn in through a dust inlet via a connecting pipe and a connecting block, and then introduced into a water-filled dust collection box. The water helps to adsorb the dust to a certain extent, and the gas is dispersed by an aeration plate, thus improving the dust removal effect. Furthermore, heat dissipation holes facilitate heat dissipation, enhancing the device's heat dissipation effect. A matching dustproof net is laid inside the heat dissipation groove, and a matching magnetic strip is fixedly connected to the outside of the dustproof net, facilitating removal and cleaning, further improving the device's dustproof effect, measurement accuracy, and overall quality.

[0004] When stress testing glass, it will be subjected to a certain degree of compression. When the glass is compressed, it is easy for the glass to shift in position due to the compression force, which will reduce the accuracy of stress testing. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a glass surface stress detection device, which can effectively solve the problem that when the glass is subjected to stress detection, a certain degree of compression is applied to the glass. When the glass is compressed, it is easy for the glass to shift its position due to the compression force, which leads to a decrease in the accuracy of stress detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a glass surface stress detection device, including a mounting plate. A guide groove is formed in the middle of the surface of the mounting plate. A servo motor is fixedly installed on one side of the guide groove. A bidirectional lead screw is fixedly installed at the output end of the servo motor. Positioning components are threaded to both sides of the surface of the bidirectional lead screw. Support plates are fixedly installed on both sides of the surface of the mounting plate. A sliding groove is formed on the surface of the support plate. A detection component is arranged inside the sliding groove.

[0008] The positioning assembly includes guide blocks threaded to both sides of the surface of a bidirectional lead screw. A clamping frame is fixedly installed on the surface of the guide blocks. A plurality of telescopic rods are fixedly installed on the surface of the clamping frame. A spring is sleeved on the surface of each telescopic rod. A clamping plate is fixedly installed at one end of each telescopic rod.

[0009] The clamping plates are positioned opposite each other on the surface of the mounting plate, and the size of the clamping plates is adapted to the size of the clamping frame.

[0010] The guide block has a threaded groove on its surface, and the size of the threaded groove is adapted to the diameter of the bidirectional lead screw.

[0011] The detection component includes a rotating groove formed on the surface of a support plate. A reciprocating lead screw is rotatably connected inside the rotating groove. A sliding block is threadedly connected to the surface of the reciprocating lead screw. A positioning groove is formed on the surface of the sliding block. A crossbar is provided inside the positioning groove. A pressing block is fixedly installed in the middle of the surface of the crossbar.

[0012] The bottom of the extrusion block is provided with a limiting groove, and a buffer pad is provided inside the limiting groove. The buffer pad is made of rubber.

[0013] Support feet are fixedly installed at the four corners of the bottom of the mounting plate, and anti-slip pads are fitted onto the surface of the support feet.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] By utilizing a servo motor, a bidirectional lead screw, and a positioning component, the servo motor is powered on during use. Its output will drive the bidirectional lead screw to rotate. As the bidirectional lead screw rotates, it will cause the clamping frame to move synchronously towards the center. The clamping plate inside the clamping frame will clamp and position the glass, reducing the occurrence of glass position deviation during glass inspection.

[0016] By utilizing the support plate and detection components, during use, the operator rotates the reciprocating screw via the support plate. As the reciprocating screw rotates, it causes the pressing block on the crossbar to move downwards. The pressing block presses against the glass, and during this pressing, the stress of the glass is detected, thus enabling rapid stress detection of the glass. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 4 A glass surface stress detection device includes a mounting plate 1, with support feet fixedly installed at the four corners of the bottom of the mounting plate 1. Anti-slip pads are fitted onto the surface of the support feet. A guide groove is formed in the middle of the surface of the mounting plate 1. A servo motor 2 is fixedly installed on one side of the guide groove. A bidirectional lead screw 3 is fixedly installed at the output end of the servo motor 2. Positioning components 4 are threadedly connected to both sides of the surface of the bidirectional lead screw 3. Support plates 5 are fixedly installed on both sides of the surface of the mounting plate 1. A sliding groove is formed on the surface of the support plate 5. A detection component 6 is arranged inside the sliding groove. Example 1

[0026] The positioning component 4 includes guide blocks 41 threadedly connected to both sides of the surface of the bidirectional lead screw 3. A clamping frame 42 is fixedly installed on the surface of the guide blocks 41. Several telescopic rods 43 are fixedly installed on the surface of the clamping frame 42. Springs 44 are sleeved on the surface of the telescopic rods 43. A clamping plate 45 is fixedly installed at one end of the telescopic rod 43. The clamping plate 45 is arranged opposite to the surface of the mounting plate 1. The size of the clamping plate 45 is adapted to the size of the clamping frame 42. A threaded groove is opened on the surface of the guide blocks 41. The size of the threaded groove is adapted to the diameter of the bidirectional lead screw 3.

[0027] During use, the operator connects the servo motor 2 to the power supply, and its output end will drive the bidirectional lead screw 3 to rotate. When the bidirectional lead screw 3 rotates, it will drive the guide block 61 to move to the middle or both sides. When the guide block 61 moves, it will drive the clamping frame 42 to move. The clamping plate 45 comes into contact with the glass, and the clamping plate 44 will squeeze the spring 44 on the telescopic rod 43. After being squeezed, the spring 44 will return to its original position, clamping and positioning the glass on the clamping plate 45. Example 2

[0028] The detection component 6 includes a rotating groove formed on the surface of the support plate 5. A reciprocating screw 61 is rotatably connected inside the rotating groove. A sliding block 62 is threadedly connected to the surface of the reciprocating screw 61. A positioning groove is formed on the surface of the sliding block 62. A crossbar 63 is set inside the positioning groove. A pressing block 64 is fixedly installed in the middle of the surface of the crossbar 63. A limiting groove is formed at the bottom of the pressing block 64. A buffer pad is set inside the limiting groove. The buffer pad is made of rubber.

[0029] During use, the operator will rotate the reciprocating screw 61 through the support plate 5. When the reciprocating screw 61 rotates, the sliding block 62 will be guided by the support plate 5. When the sliding block 62 is guided, it will move up and down. The crossbar 63 will then drive the pressing block 64 to move downward. The buffer pad on the pressing block 64 will come into contact with the glass, and the pressing block 64 will perform stress detection on the glass.

[0030] Working principle: First, the servo motor 2 is powered on, and its output will drive the bidirectional lead screw 3 to rotate. When the bidirectional lead screw 3 rotates, it will drive the guide block 61 to move to the middle or both sides. When the guide block 61 moves, it will drive the clamping frame 42 to move. The clamping plate 45 will contact the glass, and the clamping plate 44 will compress the spring 44 on the telescopic rod 43. After being compressed, the spring 44 will return to its original position, clamping and positioning the glass on the clamping plate 45. Then, the reciprocating lead screw 61 is rotated through the support plate 5. When the reciprocating lead screw 61 rotates, it will guide the sliding block 62 through the support plate 5. When the sliding block 62 is guided, it can move up and down. The crossbar 63 will drive the pressing block 64 to move downward. The buffer pad on the pressing block 64 will contact the glass, and the pressing block 64 will perform stress detection on the glass.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
