Description

Technical Field

[0001] The present invention relates to the technical field related to glass production, in particular to an energy-saving glass production testing device. Background Art

[0002] As is known to all, traditional glass is used in buildings only for lighting. As the size of doors and windows of buildings increases, the requirements for thermal insulation of doors and windows also increase accordingly. Energy-saving decorative glass is a glass that can meet this requirement. It combines energy saving and decorative properties. Energy-saving decorative glass has special light and heat absorption, transmission and reflection capabilities.

[0003] During the production process of energy-saving glass, it needs to be tempered. After the tempering is completed, it needs to be subjected to an impact resistance test to ensure that the energy-saving glass has good impact resistance in daily use. In the existing technology, when conducting an impact resistance test on the tempered energy-saving glass, the glass is fixed on a frame and a striking ball is pulled by a rope so that the striking ball swings down from a specified height to hit the glass surface. The glass after the impact is then tested to determine whether the produced tempered energy-saving glass meets the impact resistance requirements.

[0004] For example, a high-strength laminated glass impact resistance testing device with announcement number CN214622124U and announcement date November 5, 2021, aims to solve the technical problem of the single detection method of the existing technology. Its technical solution is: it includes a supporting base, and the supporting base is provided with a vertical frame for fixing the laminated glass, and the top of the vertical frame is provided with an impact assembly; the impact assembly includes an impact part for impacting the laminated glass, and also includes an adjusting part for adjusting the position of the impact part, the impact part includes a counterweight block and a counterweight rope, the adjusting part includes an adjusting rod, and the adjusting rod is arranged on the top of the vertical frame. One end of the counterweight rope is fixedly connected to the counterweight block, and the other end is connected to the adjusting rod. This application has the technical effect of improving the impact diversity of laminated glass and improving the detection quality of the impact resistance testing device.

[0005] In the prior art, when testing glass that has undergone an impact resistance test, the test is conducted by simply striking multiple pieces of glass. The tester then observes the condition of the glass after the impact. When several consecutive pieces of glass are not damaged, the tester determines that the glass has qualified impact resistance. However, the disadvantage is that even if the glass does not show obvious damage after being struck, there may be fine cracks, which are difficult for the tester to observe with the naked eye. Moreover, these cracks may become stress concentration points, thereby causing the glass to explode. Summary of the Invention

[0014] As mentioned above, the gravity of the optical detection unit is greater than the gravity of the pendulum ball, and the gravity of the optical detection unit is greater than the sum of the gravity of the fixture and the glass.

[0015] As mentioned above, the clamping member includes two oppositely arranged clamping blocks. When the clamping blocks clamp the pendulum ball, the shape of the clamping blocks adapts to the shape of the pendulum ball; after the pulley pushes the pendulum ball into the clamping space, it continues to move toward one end of the cantilever, and the two clamping blocks clamp the pendulum ball based on the extrusion force of the wire block; when the wire block moves toward the other end of the cantilever, when the rope part between the pendulum ball and the pulley is completely straightened, the two clamping blocks remove the clamping effect on the pendulum ball based on the extrusion force of the wire block.

[0016] As mentioned above, two rod bodies are slidably provided in the length direction of the cantilever, and each rod body is provided with a first pressure-bearing part at one end close to the clamping member, and each rod body is provided with a second pressure-bearing part at one end away from the clamping member; when the wire block moves toward one end of the cantilever, it can squeeze the two first pressure-bearing parts at the same time, and the two clamping blocks clamp the pendulum ball based on the squeezing force of the two first pressure-bearing parts, and when the wire block moves toward the other end of the cantilever, it can squeeze the two second pressure-bearing parts at the same time, and the two second pressure-bearing parts drive the two first pressure-bearing parts to remove the squeezing effect on the two clamping blocks through their respective corresponding rod bodies.

[0028] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1 To the attached Figure 6 The present invention is further described in detail.

[0029] An embodiment of the present invention provides an energy-saving glass production and testing device, including a frame 1 and a cantilever 2 provided on the frame 1. A pendulum ball 21 is connected to the cantilever 2 via a pull rope 20. The frame 1 is also provided with a clamp 22 for clamping the glass to be tested. The pendulum ball 21 strikes the glass 5 during its swinging stroke. The device also includes: an optical detection unit 3, which is used to perform optical crack detection on the glass 5 after being struck by the pendulum ball 21.

[0030] Specifically, the frame 1 and the cantilever 2 form a horizontal folding structure, the cantilever 2 is at the upper end of the frame 1, and the lower end of the frame 1 is fixed to the ground. The pull rope 20 is made of a material that is inelastic or has negligible elasticity. One end of the pull rope 20 can be fixed on the cantilever 2, and the other end is connected to the pendulum ball 21. The weight of the pendulum ball 21 is arranged according to the needs of the actual glass for impact strength testing, and the swing starting point height of the pendulum ball 21 is also arranged according to the needs of the actual glass for impact strength testing, and the area where the glass 5 is hit by the pendulum ball 21 is located within 25 mm near the center of the glass. The optical detection unit 3 works on the principle of using a light source to emit parallel light to vertically illuminate one side of the hit glass 5, and then observing whether the light emitted from the other end of the glass is refracted. If refraction occurs, it means that the glass 5 has a crack. If no refraction occurs, it means that the glass 5 has no crack and its impact resistance performance is qualified.

[0031] After the glass is hit by the pendulum ball 21, the following situations may occur: situation 1, the glass is not broken, but there are obvious cracks or subtle cracks; situation 2, the glass is directly broken; situation 3, the glass is intact; when the optical detection unit 3 set in this embodiment detects the glass after the impact, if the glass in situation 3 appears, it means that the impact resistance of the glass is qualified; if the glass in situations 1 and 2 appears, it means that the impact resistance of the glass is unqualified. In particular, in situation 1, when the glass after being hit by the pendulum ball 21 has subtle cracks that are difficult to be clearly observed by the naked eye of the inspector, the optical detection unit 3 of this embodiment can better detect the subtle cracks on the glass.

[0032] The beneficial effect of this embodiment is that by providing the optical detection unit 3, the glass struck by the pendulum ball 21 can be optically inspected to detect some fine cracks that are difficult for inspectors to observe with the naked eye, thereby better judging the impact resistance of the glass.

[0033] In this embodiment, when the optical detection unit 3 is working, the impact-resistant glass 5 it detects is the one with inconspicuous cracks as in situation 1. In subsequent embodiments, the optical detection unit 3 also works under this situation.

[0034] Furthermore, the optical detection unit 3 moves vertically on the frame 1 based on the driving force of a driving member. After the glass is hit by the pendulum ball 21, the optical detection unit 3 moves vertically upward under the driving action of the driving member to perform optical detection on the glass.

[0035] Specifically, a first slide groove 10 is provided on the frame 1, and a first slider 11 is slidably arranged in the first slide groove 10. The optical detection unit 3 is fixed to the first slider 11. The driving member can drive the first slider 11 to reciprocate vertically in the first slide groove 10, such as a screw transmission mechanism. When the pendulum ball 21 swings and hits the glass, the glass is likely to be broken. Even if the glass is not completely broken the first time, that is, as in case 1, the glass has obvious cracks, then the pendulum ball 21 rebounds after hitting the glass and then swings back to hit the glass, the glass is still likely to be broken, and the broken glass fragments will fly along the impact direction, and the glass fragments will have the risk of damaging the optical detection unit 3. Therefore, to protect the optical detection unit 3, from the beginning to the end of the pendulum ball 21 hitting the glass, the optical detection unit 3 is at the lowest position on the frame 1, that is, the optical detection unit 3 is offset from the glass in the horizontal direction. After the glass is hit by the pendulum ball 21, if the glass is not broken or has no obvious cracks, the driving member drives the optical detection unit 3 to move upward to perform optical scanning and detection on the glass.

[0036] The splashing of glass after being broken is basically in the form of oblique upward, horizontal or oblique downward throwing, and the splashing glass fragments still come into contact with the optical detection unit 3. Therefore, in this embodiment, further, when the swing ball 21 swings and hits the glass, the optical detection unit 3 is in an inclined state, that is, the first chute 10 is divided into two sections, the first section 100 is arranged vertically, and the second section 101 is arranged obliquely, and the high end of the second section 101 is connected to the lowest end of the second section 101. The first slider 11 is cylindrical and can slide or roll in the first chute 10. There are two of them, and the outer surface of the optical detection unit 3 is The upper end of the frame is rotatably connected to one of the first sliders 11, and the lower end of the outer frame of the optical detection unit 3 is rotatably connected to the other first slider 11. In this way, when the optical detection unit 3 moves downward, the first slider 11 connected to the lower end of the outer frame of the optical detection unit 3 will enter the second section 101 from the first section 100. Then the outer frame of the optical detection unit 3 will be deflected about the axis connected to the first slider 11 at the upper end, so that the entire optical detection unit 3 is tilted. After the tilt, the side of the optical detection unit 3 that emits light is tilted downward, so as to avoid contact with it by flying glass shards.

[0037] Preferably, the clamp 22 is vertically slidably arranged on the frame 1, and a transmission assembly is also provided on the frame 1, which is used to transmit power between the optical detection unit 3 and the clamp 22. When the optical detection unit 3 moves vertically upward, the clamp 22 drives the glass to move vertically downward.

[0038] Specifically, the clamp 22 is mainly used to clamp the glass from the four corners of the glass to be tested. This is not described in detail in the prior art. The clamp 22 can slide vertically on the frame 1, that is, a second slide groove 12 parallel to the first section 100 of the first slide groove 10 is provided on the frame 1, and a second slider 13 is also provided in the second slide groove 12. The clamp 22 is fixed to the second slider 13, and power is transmitted between the second slider 13 and the optical detection unit 3 through a transmission assembly. In an optional embodiment, the transmission assembly includes a first rack 14 provided on the optical detection unit 3, a second rack 15 provided on the clamp 22, and a gear 16 that is simultaneously engaged with the first rack 14 and the second rack 15. The teeth of the first rack 14 are connected to the second rack 15. The teeth of the second rack 15 are arranged relative to each other. In this way, when the optical inspection unit 3 moves downward, it will drive the first rack 14 to move synchronously. The movement of the first rack 14 drives the gear 16 meshing with it to rotate. The rotation of the gear 16 drives the second rack 15 meshing with it to move in the opposite direction of the first rack 14. That is, after the glass is hit by the pendulum ball 21, when the optical inspection unit 3 needs to be inspected, the driving member drives the optical inspection unit 3 to move upward. Under the action of the transmission assembly, the clamp 22 moves the glass downward. During the relative movement of the two, the optical inspection unit 3 completes the inspection of the glass. In this way, the inspection time of the glass after being hit by the pendulum ball 21 can be shortened, thereby improving the inspection efficiency of the glass.

[0039] Furthermore, the driving member is a screw transmission mechanism arranged on the cantilever 2, and a pulley 24 is provided on the screw block 23 of the screw transmission mechanism, and the pull rope 20 is in rolling contact with the pulley 24. The cantilever 2 is provided with a clamping member 4 for clamping the pendulum ball 21, and one end of the pull rope 20 is connected to the pendulum ball 21, and the other end is connected to the optical detection unit 3; in the movement stroke of the screw block 23 toward one end of the cantilever 2, the pulley 24 pushes the pendulum ball 21 into the clamping space of the clamping member 4, and the pull rope 20 pulls the optical detection unit 3 to move vertically upward; in the movement stroke of the screw block 23 toward the other end of the cantilever 2, the screw block 23 straightens the part of the pull rope 20 between the pendulum ball 21 and the pulley 24, and the optical detection unit 3 moves vertically downward under the action of its own gravity.

[0040] Specifically, when the glass is subjected to an impact resistance test, the pendulum ball 21 should swing down from a calibrated height to impact the central area of ​​the glass. Therefore, the position of the clamping member 4 is the position of the calibrated height of the pendulum ball 21. When the wire block 23 drives the pulley 24 to move from the other end of the cantilever 2 to the one end, the distance between the pulley 24 and the pendulum ball 21 is shortened, that is, the pendulum length of the pendulum ball 21 is shortened. In this way, the swing path of the pendulum ball 21 is getting shorter and shorter. Therefore, during the rebound process after the pendulum ball 21 hits the glass for the first time, the wire block 23 drives the pulley 24 to move from the other end of the cantilever 2 to the one end. In this way, the pendulum ball 21 will not rebound and hit the glass. Even if the pendulum ball 21 hits the glass for the first time and obvious cracks appear on the glass, the pendulum ball 21 will not hit the glass again due to rebound, and the risk of the glass being broken is avoided. This not only prevents glass shards from splashing, but also shortens the time of the glass impact resistance test.

[0041] One end of the pull rope 20 is connected to the swing ball 21, and the other end is connected to the optical detection unit 3. In this embodiment, when the pulley 24 pushes the swing ball 21 into the clamping space, the optical detection unit 3 can also move up to detect the glass after the impact. Therefore, when the pulley 24 moves from the other end to the one end of the cantilever 2, it is necessary to generate a force on the pull rope 20 so that the pull rope 20 can pull the optical detection unit 3 to move up. Therefore, a block 25 is fixed to the pull rope 20, and the block is always on the part of the pull rope 20 between the pulley 24 and the swing ball 21. After the pendulum ball 21 hits the glass and rebounds, the wire block 23 drives the pulley 24 to move from the other end of the cantilever 2 to one end. There are two processes. In the first process, when the pulley 24 is in contact with the block 25, the movement of the pulley 24 is mainly to shorten the swing length of the pendulum ball 21 to prevent the pendulum ball 21 from swinging and hitting the glass again. In the second process, the pulley 24 contacts the block 25 and generates a thrust on the block 25. The block 25 drives the pull rope 20 to move. The pull rope 20 drives the optical detection unit 3 to move upward to detect the glass. At the same time, the block 25 also pushes the pendulum ball 21 into the clamping space.

[0042] After the pendulum ball 21 is clamped by the clamp 4, the optical detection unit 3 has completed the inspection of the glass. Then, the glass needs to be removed from the clamp 22 and replaced with another glass that needs to be subjected to the impact resistance test. Therefore, the wire block 23 drives the pulley 24 to move from one end of the cantilever 2 to the other end. The pendulum ball 21 is clamped by the clamp 4 and is affected by the gravity of the optical detection unit 3. During this process, the pull rope 20 will be straightened. After the pendulum length of the pendulum ball 21 is determined, the position of the optical detection unit 3 should also be consistent with the position of the clamp 22. The optical detection unit 3 is staggered, that is, the optical detection unit 3 reaches its lowest point on the frame 1 and is in a tilted state. After the clamping member 4 removes the clamping of the pendulum ball 21, the pendulum ball 21 will swing downward, and the pendulum length of the pendulum ball 21 should remain basically unchanged to avoid the position of the pendulum ball 21 hitting the glass being offset. Therefore, the gravity of the optical detection unit 3 is greater than the gravity of the pendulum ball 21, and the gravity of the optical detection unit 3 is greater than the sum of the gravity of the clamp 22 and the glass. In this way, when the glass is subjected to the impact resistance test, the glass can always be in the impacted position.

[0043] Preferably, the clamping member 4 includes two oppositely arranged clamping blocks 40. When the clamping blocks 40 clamp the pendulum ball 21, the shape of the clamping blocks 40 adapts to the shape of the pendulum ball 21; after the pulley 24 pushes the pendulum ball 21 into the clamping space, it continues to move toward one end of the cantilever 2, and the two clamping blocks 40 clamp the pendulum ball 21 based on the squeezing force of the wire block 23; when the wire block 23 moves toward the other end of the cantilever 2, when the pull rope 20 between the pendulum ball 21 and the pulley 24 is completely straightened, the two clamping blocks 40 remove the clamping effect on the pendulum ball 21 based on the squeezing force of the wire block 23.

[0044] Specifically, the two clamping blocks 40 of the clamping member 4 can adopt an active method for clamping the swing ball 21, such as setting a driving source between the two clamping blocks 40, and the driving source can drive the two clamping blocks 40 to move closer to and away from each other, or a passive method can be adopted, such as using the reciprocating movement of the wire block 23 on the cantilever 2, that is, sliding in the length direction of the cantilever 2. Two rod bodies 41 are provided, and one end of each rod body 41 close to the clamping member 4 is provided with a first pressure-bearing part 42, and one end of each rod body 41 away from the clamping member 4 is provided with a second pressure-bearing part 43, a first wedge-shaped surface is provided on the first pressure-bearing part 42, and a second wedge-shaped surface is provided on the clamping block 40, and the first wedge-shaped surface and the second wedge-shaped surface are wedge-shaped. The two clamping blocks 40 are matched, and an elastic member is provided between the two clamping blocks 40. Based on the elastic force of the elastic member, the two clamping blocks 40 tend to always move away from each other. When the wire block 23 moves toward one end of the cantilever 2, it can squeeze the two first pressure-bearing parts 42. The two first pressure-bearing parts 42 jointly squeeze the two clamping blocks 40 to clamp the pendulum ball 21. When the wire block 23 moves toward the other end of the cantilever 2, it can squeeze the two second pressure-bearing parts 43. The movement of the two rod bodies 41 drives the two first pressure-bearing parts 42 to remove the squeeze on the two clamping blocks 40 to release the clamping of the pendulum ball 21, that is, the first wedge surface and the second wedge surface are moved away from each other. Under the elastic force of the elastic member, the two clamping blocks 40 remove the clamping of the pendulum ball 21.

It is understood that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the present invention.
