Description

Technical Field

[0001] This utility model relates to the field of insulating glass technology, specifically to an insulating glass fatigue fogging test device. Background Technology

[0002] The sealing integrity of insulated glass is crucial to its long-term performance, primarily relying on butyl sealant to bond and seal the glass to the aluminum spacer frame. However, during the manufacturing process, butyl sealant may contain microscopic defects such as internal air bubbles and uneven coating, resulting in product quality variations. These issues are often difficult to detect in the early stages of product use.

[0003] During long-term use, changes in ambient temperature cause the gas inside the insulated glass cavity to expand and contract, leading to a pressure difference between the inside and outside of the cavity. This pressure difference causes the two panes of glass to be subjected to repeated alternating loads (pushing outwards or pulling inwards). This continuous mechanical stress will constantly act on the butyl sealant system, causing the initial microscopic defects to gradually expand and eventually evolve into a continuous leakage channel, resulting in the failure and fogging of the insulated glass.

[0004] Therefore, it is crucial to accelerate the fatigue process of butyl rubber under alternating loads and expose these sealing defects in advance through effective sampling inspection before leaving the factory, which is essential for product quality control and assembly process improvement.

[0023] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] See Figures 1 to 4 A fatigue fogging test device for insulating glass includes a controller assembly.

[0025] The controller components include a PLC controller, a servo electric cylinder driver, a control panel, and a signal transmitter for the tension / compression sensor. The PLC controller can be a SMART200 model. It is a conventional technique to connect the corresponding electrical control equipment mentioned in this disclosure to the PLC controller through the corresponding driver or signal transmitter, which will not be described in detail here.

[0026] The device disclosed herein also includes a base plate 1 and a top plate 6 suspended above the base plate 1, wherein the base plate 1 and the top plate 6 are welded together by four support rods 5. The base plate 1 and the top plate 6 are parallel to each other, and the support rods 5 are perpendicular to the base plate 1 and the top plate 6.

[0027] The upper end face of the base plate 1 is provided with a lower lifting mechanism that moves vertically, and the lower end face of the top plate 6 is provided with an upper lifting mechanism that moves vertically. The bottom of the upper lifting mechanism is horizontally mounted with an upper mounting plate 19, and the top of the lower lifting mechanism is horizontally mounted with a lower mounting plate 14.

[0028] Specifically, the lower mounting plate 14 is a rectangular plate, and the lower lifting mechanism includes four outer sliding cylinders 2 and four inner sliding cylinders 3 vertically welded or screwed to the upper end face of the base plate 1. Both the outer sliding cylinders 2 and the inner sliding cylinders 3 are cylindrical. An outer sliding rod 12 is vertically slidably inserted inside the four outer sliding cylinders 2, and an inner sliding rod 11 is vertically slidably inserted inside the four inner sliding cylinders 3. The four outer sliding cylinders 2 are distributed on the base plate 1 at the four corners of a virtual rectangle, and the four inner sliding cylinders 3 are similarly distributed on the base plate 1 at the four corners of a virtual rectangle. The inner sliding cylinders 3 are located within the encirclement formed by the four outer sliding cylinders 2, and at the center of the encirclement. The top of the outer sliding rod 12 is welded to the lower end face of the lower mounting plate 14, and the top of the inner sliding rods 11 is also welded to a horizontally arranged lower connecting plate 10. The lower connecting plate 10 is a rectangular plate, and lower connecting rods 13 are welded to the four corners of the lower connecting plate 10. The top of the lower connecting rods 13 is welded to the corresponding corner of the lower end face of the lower mounting plate 14.

[0029] With this structural layout, the lower connecting plate 10 can control the vertical rise and fall of the lower mounting plate 14 by uniformly applying force through the lower connecting rod 13. The arrangement of the four outer sliding cylinders 2, outer sliding rods 12 and the four inner sliding cylinders 3, inner sliding rods 11 can effectively limit the lifting and lowering direction of the lower mounting plate 14 and the lower connecting plate 10, resulting in uniform force and relative stability.

[0030] A lower servo cylinder 4 is screwed and fixed to the upper end face of the base plate 1. The telescopic rod of the lower servo cylinder 4 extends vertically upward and is fixedly connected to the bottom of the lower connecting plate 10 by screwing. It should be noted that in this disclosure, a perforated plate is welded vertically downward to the bottom of the lower connecting plate 10. The telescopic rod of the lower servo cylinder 4 is connected to this perforated plate through a connector. Since this is a common installation method in the prior art, the detailed structure is not shown in the attached drawings.

[0031] The lower servo cylinder 4 is electrically connected to the servo cylinder driver and the PLC controller.

[0032] Specifically, the upper mounting plate 19 is a rectangular plate, and the upper lifting mechanism includes four outer upper sliding cylinders 7 and four inner upper sliding cylinders 8 vertically welded or screwed to the lower end face of the top plate 6. Both the outer upper sliding cylinders 7 and the inner upper sliding cylinders 8 are cylindrical. Outer upper sliding rods 17 are vertically slidably inserted inside the four outer upper sliding cylinders 7, and inner upper sliding rods 16 are vertically slidably inserted inside the four inner upper sliding cylinders 8. The four outer upper sliding cylinders 7 are distributed on the top plate 6 at the four corners of a virtual rectangle, and the four inner upper sliding cylinders 8 are similarly distributed on the top plate 6 at the four corners of a virtual rectangle. The inner upper sliding cylinders 8 are located within the encirclement formed by the four outer upper sliding cylinders 7, and at the center of the encirclement. The bottom of the outer upper sliding rods 17 is welded to the upper end face of the upper mounting plate 19, and the bottom of the inner upper sliding rods 16 are also welded to a horizontally arranged upper connecting plate 15. The upper connecting plate 15 is a rectangular plate, and upper connecting rods 18 are welded to the four corners of the upper connecting plate 15. The bottom of the upper connecting rods 18 is welded to the corresponding corners of the upper end face of the upper mounting plate 19.

[0033] With this structural layout, the upper connecting plate 15 can control the vertical rise and fall of the upper mounting plate 19 by uniformly applying force through the upper connecting rod 18. The arrangement of the four outer upper sliding cylinders 7, outer upper sliding rods 17 and four inner upper sliding cylinders 8, inner upper sliding rods 16 can effectively limit the lifting and lowering direction of the upper mounting plate 19 and the upper connecting plate 15, resulting in uniform force and relative stability.

[0034] The lower end face of the top plate 6 is also screwed and fixedly fitted with an upper servo cylinder 9. The telescopic rod of the upper servo cylinder 9 extends vertically downward and is fixedly connected to the top of the upper connecting plate 15 by screwing. It should be noted that in this disclosure, a perforated plate is welded vertically upward to the top of the upper connecting plate 15. The telescopic rod of the upper servo cylinder 9 is connected to this perforated plate through a connector. Since this is a common installation method in the prior art, the detailed structure is not shown in the attached drawings.

[0035] The upper servo cylinder 9 and the servo cylinder driver are electrically connected to the PLC controller.

[0036] Multiple vacuum suction cups 28 are mounted on the lower end face of the upper mounting plate 19, and multiple vacuum suction cups 28 are mounted on the upper end face of the lower mounting plate 14.

[0037] Specifically, the lower end of the upper mounting plate 19 has multiple countersunk holes 26 facing upwards, and the top of the multiple countersunk holes 26 of the upper mounting plate 19 also has threaded holes 27 facing upwards. The vacuum suction cup 28 includes a suction cup part and a hollow screw 32 part. The hollow screw 32 part of the vacuum suction cup 28 is screwed through and installed in the threaded holes 27 of the upper mounting plate 19 and extends upwards. The top of the suction cup part of the vacuum suction cup 28 abuts against the top of the countersunk holes 26 of the upper mounting plate 19, and the bottom of the suction cup parts of the multiple vacuum suction cups 28 on the upper mounting plate 19 are at the same horizontal plane.

[0038] Specifically, the upper end of the lower mounting plate 14 has multiple countersunk holes 26 facing downwards, and the bottom of the multiple countersunk holes 26 of the lower mounting plate 14 also has a threaded hole 27 facing downwards. The hollow screw 32 of the vacuum suction cup 28 is screwed through and installed in the threaded hole 27 of the lower mounting plate 14 and extends downwards. The top of the suction cup part of the vacuum suction cup 28 abuts against the bottom of the countersunk hole 26 of the lower mounting plate 14, and the bottom of the suction cup parts of the multiple vacuum suction cups 28 on the lower mounting plate 14 are on the same horizontal plane.

[0039] It should be noted that the vacuum suction cups 28 on the upper mounting plate 19 and the lower mounting plate 14 refer to suction cups that adhere to the surface of an object by pressing the suction cup part against it, and then forming a negative pressure in the suction cup part by evacuating air through the hollow screw 32 part connected to the air extraction pipe, thereby adsorbing the object. There are many models of existing products that can meet the adsorption requirements of this disclosure. The vacuum suction cup 28 structure recommended in this disclosure is only as the inventor's understanding of the best implementation structure, and does not constitute an absolute limitation on the selection of the vacuum suction cup 28 structure.

[0040] It should be noted that the vacuum suction cups 28 on the upper mounting plate 19 and the lower mounting plate 14 are arranged in a way that combines uniform distribution with meeting suction requirements. The specific locations of these suction cups are not fixed; details are provided in this disclosure. Figure 4 The arrangement method can be considered as one of the preferred arrangement methods.

[0041] The lower end face of the top plate 6 is also provided with an upper mounting bracket, on which an upper pull pressure sensor 25 is provided. The upper pull pressure sensor 25 is fixedly connected to the midpoint of the upper end face of the upper mounting plate 19. The upper end face of the bottom plate 1 is also provided with a lower mounting bracket, on which a lower pull pressure sensor 22 is provided. The lower pull pressure sensor 22 is fixedly connected to the midpoint of the lower end face of the lower mounting plate 14.

[0042] Specifically, the lower mounting bracket includes a lower vertical rod 20 that is welded or screwed onto the upper end face of the base plate 1. A lower mounting bracket 21 is detachably screwed onto the lower vertical rod 20. A pull-down pressure sensor 22 is detachably screwed onto the top of the lower mounting bracket 21. A screw 32 is vertically fixed at the center of the lower end face of the lower mounting plate 14. The top of the pull-down pressure sensor 22 is screwed to the screw 32 of the lower mounting plate 14.

[0043] Specifically, the upper mounting bracket includes an upper vertical rod 23 that is welded or screwed onto the lower end face of the top plate 6. An upper mounting frame 24 is detachably screwed onto the upper vertical rod 23. An upper tension pressure sensor 25 is detachably screwed onto the bottom of the upper mounting frame 24. A screw 32 is vertically fixed at the center of the upper end face of the upper mounting plate 19. The top of the upper tension pressure sensor 25 is screwed onto the screw 32 of the upper mounting plate 19.

[0044] It should be noted that the lower mounting bracket 21 and the upper mounting bracket 24 can be L-shaped or other shapes. The main purpose is to avoid the upper connecting plate 15 and the lower connecting plate 10, and to install the tension / compression sensor near the center of the upper mounting plate 19 and the lower mounting plate 14. As for the screw connection method between the vertical rod and the mounting bracket, the screw connection method between the mounting bracket and the tension / compression sensor is a common technical means in the prior art, and the attached drawings and descriptions will not be given in detail here.

[0045] By designing the upper and lower mounting brackets into vertical rods and mounting frames, two advantages are achieved: firstly, it facilitates the selection of the size and structure of the mounting frame according to actual conditions; and secondly, it facilitates the overall installation and disassembly of the device.

[0046] Both the pull-up pressure sensor 25 and the pull-down pressure sensor 22 are electrically connected to the PLC controller through their respective signal transmitters.

[0047] Working principle of this utility model:

[0048] When using this device, a batch of insulating glass units is sampled for inspection. First, the telescopic cylinder of the lower servo cylinder 4 is extended upward to a predetermined position and set as the initial position. After the pull-down pressure sensor 22 is installed, its reading is reset to zero. The sampled insulating glass unit is placed on the lower mounting plate 14, and external air pipes are connected to the vacuum suction cups 28 on the lower mounting plate 14. The vacuum equipment is then activated to suction the glass 29 at the lower end of the insulating glass unit. Under the weight of the insulating glass unit, the reading of the pull-down pressure sensor 22 indicates downward pressure, and the butyl rubber strip 31 is compressed by the gravity of the upper glass 29 of the insulating glass unit.

[0049] Then, the extension rod of the upper servo cylinder 9 is extended downwards, causing the vacuum suction cup 28 of the upper mounting plate 19 to press against the upper glass 29 of the insulating glass. At this time, the downward pressure sensor 22 will detect the downward pressure. The deformation of the suction cup part of the vacuum suction cup 28 is observed visually. When the deformation of the suction cup part no longer changes, the upper servo cylinder 9 is stopped. External air pipes are connected one by one to the vacuum suction cups 28 on the upper mounting plate 19, and another air extraction device or a branch valve of the same air extraction device is started to adsorb the upper glass 29 of the insulating glass. During the adsorption process of the vacuum suction cup 28, the downward pressure sensor 22 will detect a decrease in the downward pressure value. When the adsorption is stable and the value of the downward pressure sensor 22 remains unchanged, the upper servo cylinder 9 is adjusted. If the reading of the downward pressure sensor 22 indicates downward pressure, the extension rod of the upper servo cylinder 9 is adjusted to retract upward. If the reading of the downward pressure sensor 22 indicates upward pulling force, the extension rod of the upper servo cylinder 9 is adjusted to extend downward until the reading of the downward pressure sensor 22 is zero (a deviation of ±10Nm is allowed in actual applications).

[0050] At this time, the glass 29 at both ends of the insulating glass is stably adsorbed by the vacuum suction cup 28, and the squeezing effect of the upper glass 29 on the butyl rubber 31 is eliminated.

[0051] Before testing, the movement directions of the lower servo cylinder 4 and the upper servo cylinder 9 were set to simultaneously compress and pull the insulating glass. The time and stroke were set, as well as the number of cycles. For example, within 0-3 seconds after startup, the extension rod of the lower servo cylinder 4 extends upwards at a constant speed of 1mm, and the extension cylinder of the upper servo cylinder 9 extends downwards at a constant speed of 1mm. Within 3-6 seconds after startup, the extension rod of the lower servo cylinder 4 retracts downwards at a constant speed of 2mm, and the extension cylinder of the upper servo cylinder 9 retracts upwards at a constant speed of 2mm. 0-6 seconds is considered one cycle.

[0052] After multiple cycles of testing, the insulating glass was removed and placed in a foggy environment (composed of fogging and a sealed box) to observe whether fog formed inside the insulating glass.

[0053] Using the ideal gas law pv=nRT, the volume and area inside the aluminum spacer frame 30 of the insulating glass are first calculated. The internal gas temperature to be tested is set, and the internal pressure P1 at the corresponding gas temperature can be calculated. Combined with the external atmospheric pressure P0, the pressure difference can be calculated. The pressure or tension on the glass 29 is calculated using the formula F=PA. Using the readings of the upper pressure sensor 25 and the lower pressure sensor 22, the stroke of the upper servo cylinder 9 and the lower servo cylinder 4 is determined through experiments, thus completing the setting of the servo cylinder stroke.

[0054] The advantage of this device is that, through the precise control of the servo electric cylinder and tension / compression sensors, it actively and controllably simulates the mechanical load generated by pressure changes on the glass 29, and through multiple cycles, it quickly detects the mechanical fatigue resistance of butyl rubber 31, significantly shortening the detection time and improving the product detection efficiency.

[0055] This device, through the coordinated arrangement of connecting rods, connecting plates, sliding cylinders, and sliding bars, enables the upper mounting plate 19 and lower mounting plate 14 to rise and fall evenly under stress, thereby improving the detection accuracy of the tension and compression sensors.

[0056] This device improves the uniformity of force on the glass 29 and enhances the reliability of the detection by arranging multiple vacuum suction cups 28.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
