Description

Technical Field

[0002] Polyurethane glue is a waterproof glue with high bonding strength and elasticity, suitable for occasions that need to withstand large deformation and vibration. During the production of polyurethane glue, manufacturers need to conduct light resistance tests on each batch of glue, mainly through ultraviolet aging test chambers, such as the ultraviolet aging test chamber disclosed in patent document CN216747317U;

[0003] In the existing actual testing process, the light aging test of polyurethane glue is carried out using an ultraviolet aging test box as disclosed in the above patent, but such ultraviolet aging test boxes are all universal settings. When conducting the light aging test of polyurethane glue, a smaller glass slide is required to drip glue on the glass slide, and then multiple cured glass slides are placed in the ultraviolet aging test box, and then the box door is closed and tightened for testing. After the test, the box door is opened again to take out the glass slides one by one for observation to check the yellowing aging degree of the glue, and then the test is completed, and the glue is manually peeled off to separate the glue from the glass slide;

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] For example, see Figures 1 to 17 , This embodiment provides a technical solution: a light resistance testing device for waterproof glue processing, comprising an ultraviolet box 1, an ultraviolet lamp 101 is installed on the inner wall of the ultraviolet box 1, and a control screen 102 is fixed on the upper end of the outer wall of one side of the ultraviolet box 1. The working parts of the ultraviolet box 1 and its construction principle are all existing technologies. It mainly irradiates the sample with ultraviolet rays to accelerate its aging and test the light resistance performance of the sample;

[0050] The inner wall of the ultraviolet box 1 is installed with a support frame assembly 2 for carrying a sample tray 8, and a avoidance gap 81 is formed on one side of the sample tray 8. A sample shooting assembly 3 for shooting the sample after the light test is also fixed on the top of the inner wall of the ultraviolet box 1. A closed cover plate 4 for closing the inner wall of the ultraviolet box 1 is symmetrically rotated and installed on the outer wall of the ultraviolet box 1. A synchronous flip assembly 5 for enabling two closed covers 4 to flip at the same time is installed on the outer wall of the ultraviolet box 1. An automatic conveying assembly 6 for automatically carrying the sample tray 8 is installed on the outer wall of the ultraviolet box 1. The opening and closing of the closed cover plate 4 is mechanically linked with the automatic conveying assembly 6. A bearing support plate 7 is fixed on the outer wall of the unloading end of the ultraviolet box 1.

[0051] The detection steps are as follows:

[0052] 1. First, manual glue dispensing is required. The sample tray 8 is placed on the automatic conveying component 6 and clamped and fixed by the automatic conveying component 6. The side of the sample tray 8 with the avoidance notch 81 is ensured to be close to the UV box 1. The sample glue to be tested is evenly dripped on the sample tray 8 at intervals. It is necessary to ensure that the sample is not dripped on the part to be inserted into the support frame component 2 during the loading process on both sides of the sample tray 8;

[0053] 2. After the sample is cured and the sample test on the sample tray 8 inside the UV box 1 is completed, the automatic conveying component 6 conveys the sample tray 8 of the sample to be tested close to the UV box 1;

[0054] 3. When the sample tray 8 of the sample to be tested is close to the ultraviolet box 1, the automatic conveying component 6 can synchronously drive the closed cover plate 4 to rotate and open, and the two closed cover plates 4 can be simultaneously flipped and opened through the synchronous flipping component 5 until they are opened to a downward tilted shape. After the closed cover plates 4 are opened, the sample shooting component 3 takes a photo of the sample after the test for record;

[0055] 4. Then the automatic conveying component 6 continues to convey the sample tray 8 of the sample to be tested into the ultraviolet box 1 until it is inserted into the support frame component 2, and the sample tray 8 of the sample to be tested is supported by the support frame component 2 to complete the loading of the sample tray 8. During the loading process, the side of the sample tray 8 under the sample to be tested close to the avoidance gap 81 can push the outer wall of the sample tray 8 under the sample that has been tested and is originally located inside the ultraviolet box 1. Therefore, when the sample tray 8 under the sample to be tested is loaded in place, the sample tray 8 under the sample that has been tested can be pushed to slide out of the ultraviolet box 1 to unload;

[0056] 5. After being separated from the support frame assembly 2, the sample tray 8 falls onto the inclined closed cover plate 4 and slides onto the carrying support plate 7;

[0057] 6. After the sample to be tested is loaded, the automatic conveying component 6 releases the clamping and fixing of the sample tray 8 and resets, and then the automatic conveying component 6 resets, and during the reset process, the two closed cover plates 4 are synchronously driven to close the closed ultraviolet box 1;

[0058] 7. Turn on the ultraviolet lamp 101 to perform light resistance test on the sample to be tested;

[0059] The support frame assembly 2 includes support clips 21 symmetrically fixed to the inner wall of the ultraviolet box 1, and the two support clips 21 are formed with openings 22 for nesting the sample tray 8 on one side thereof, and a stripping assembly 23 for separating samples from the sample tray 8 is fixed on one side of the two support clips 21;

[0060] The sample tray 8 under test is in the Fig.16 The position shown, that is, when the sample tray 8 is loaded into the support frame assembly 2, the outer wall of the sample tray 8 formed with the avoidance notch 81 is flush with the outer wall of the support clip 21 near the unloading end of the ultraviolet box 1;

[0061] When the sample tray 8 loaded with the sample to be tested is transported into the inner side of the ultraviolet box 1 by the automatic conveying component 6, the side of the transported sample tray 8 formed with the avoidance notch 81 will abut against the outer wall of the sample tray 8 already on the inner side of the ultraviolet box 1. Subsequently, under the continuous conveying of the automatic conveying component 6, the sample tray 8 loaded with the sample to be tested continues to enter the inner side of the ultraviolet box 1, and pushes the sample tray 8 on which the test is completed to slide from the two support clamps 21 to one side of the unloading end of the ultraviolet box 1, until the sample tray 8 on the automatic conveying component 6 slides into the two openings 22 of the two support clamps 21, and the outer wall of one side of the sample tray 8 with the avoidance notch 81 is flush with the outer wall of one side of the support clamp 21 close to the unloading end of the ultraviolet box 1, completing the conveying and loading work, and at the same time, the sample tray 8 on which the test is completed is also pushed to slide onto the carrying tray. After the automatic conveying component 6 is reset, the sample tray 8 is supported by the two support clamps 21.

[0062] The stripping assembly 23 includes a scraper 231 fixed to one side of the two support clips 21 close to the unloading end of the UV box 1, and the bottom surface of the scraper 231 is flush with the top inner wall of the open support clip 21, and the bottom inner wall of the UV box 1 is located below the scraper 231 and is formed with an upwardly protruding inclined surface 103;

[0063] During the process of the sample tray 8 being pushed to unload after the test, as it continues to slide, the scraper 231 scrapes the sample on its surface and separates it from it, until the sample tray 8 loaded with the sample to be tested is in place, and the scraped solidified sample falls from the avoidance gap 81 of the sample tray 8 that has just been in place to the upwardly protruding inclined surface 103 formed on the inner wall of the bottom of the ultraviolet box 1 below the scraper 231 and slides out to the outside of the ultraviolet box 1. Before conducting the test, the staff can place a storage box on one side of the unloading end of the ultraviolet box 1 in contact with the outer wall of the ultraviolet box 1, and the fallen sample will automatically fall into the inside of the storage box.

[0064] The shooting component includes a first accommodating cavity 31 opened in the ultraviolet box 1 at the upper end of the inner wall thereof, the first accommodating cavity 31 is connected to the inner wall of the ultraviolet box 1, an industrial camera 32 is fixed to the inner wall of the first accommodating cavity 31, the camera end of the industrial camera 32 faces the bottom surface of the inner wall of the ultraviolet box 1, a transparent tempered glass 33 is fixed to the top of the inner wall of the ultraviolet box 1, the transparent tempered glass 33 isolates the first accommodating cavity 31 from the inner wall of the ultraviolet box 1, and the camera end of the industrial camera 32 faces the transparent tempered glass 33, a covering component 34 for covering the transparent tempered glass 33 is installed on the inner wall of the ultraviolet box 1, and the covering component 34 has a shielding state for shielding the transparent tempered glass 33 and an exposing state for exposing the transparent tempered glass 33, and the switching between the shielding state and the exposing state of the covering component 34 is mechanically linked with the opening and closing of the closing cover plate 4;

[0065] After the closed cover 4 is opened, the industrial camera 32 takes a photo of the sample after the test for record;

[0066] The covering assembly 34 includes a slide bar 341 symmetrically fixed to the inner wall of the top of the ultraviolet box 1, a covering plate 342 is slidably connected between the two slide bars 341, and the top of the covering plate 342 contacts the bottom surface of the transparent tempered glass 33, and a spring 343 is symmetrically fixed to the outer wall of the covering plate 342, and one end of the spring 343 away from the covering plate 342 is fixed to the inner wall of the ultraviolet box 1;

[0067] After the closed cover 4 is opened, due to the loss of the blocking of the closed cover 4, the spring 343 recovers its deformation and pulls the cover plate 342 to slide toward the side close to the unloading end of the UV box 1 until the spring 343 completely recovers its deformation, and the cover plate 342 opens the transparent tempered glass 33, and the cover assembly 34 switches to the exposed state, and then the industrial camera 32 can take pictures through the transparent tempered glass 33;

[0068] When the closed cover 4 is closed again, the closed cover 4 is turned over until its outer wall contacts the shielding plate 342, and then the closed cover 4 continues to close while pushing the shielding plate 342 to slide and stretch the spring 343 so that the spring 343 accumulates force, and finally the closed cover 4 is completely closed, and the shielding plate 342 also completely covers the transparent tempered glass 33 to prevent ultraviolet rays from damaging the industrial camera 32;

[0069] The closed cover plate 4 includes a rotating rod 41 fixed on the outer wall of one side thereof, and the rotating rod 41 is rotatably connected to the outer wall of the ultraviolet box 1 through a bearing. The synchronous flip assembly 5 includes synchronous gears 51 fixed at both ends of the rotating rod 41. A lifting frame 52 is symmetrically slidably connected to the outer wall of the ultraviolet box 1 through a first linear slide rail 54. Synchronous racks 53 are symmetrically fixed at both ends of the lifting frame 52. The two synchronous racks 53 at both ends of the lifting frame 52 are respectively meshed and connected with the two synchronous gears 51 at the same end of the two rotating rods 41. A limit strip 56 is fixed in the middle of the upper end of the outer wall of the ultraviolet box 1, and the limit strip 56 is directly opposite to the top surface of the lifting frame 52. The synchronous flip assembly 5 also includes a cleaning assembly 55 fixed on the lifting frame 52 for cleaning the control screen 102;

[0070] When a closed cover 4 rotates, the rotating rod 41 on it rotates together, so that the synchronous gears 51 at both ends of the rotating rod 41 rotate, and the synchronous gears 51 drive the synchronous racks 53 meshing therewith to slide. Through the arrangement of the synchronous racks 53 and the synchronous gears 51, when a closed cover 4 on one side is flipped open, the synchronous gear 51 on this side rotates to drive the synchronous racks 53 to move upward, and the two synchronous racks 53 are moved upward at the same time through the lifting frame 52, thereby driving the synchronous gear 51 on the other side to rotate, and the closed cover 4 on the other side is flipped open at the same time. The closing process is opposite to the above, and the effect of closing and opening the two closed cover 4 at the same time is achieved;

[0071] Until the two closed cover plates 4 are flipped open at the same time to present a downward tilted state, the top of the lifting frame 52 is pressed against the bottom surface of the limiting strip 56;

[0072] The cleaning assembly 55 includes a cleaning bar 551 fixed between the two lifting frames 52, a cleaning cotton 552 is fixed on the outer wall of the cleaning bar 551 close to the control screen 102, and one side of the cleaning cotton 552 is closely attached to the outer wall of the ultraviolet box 1;

[0073] When the two closed cover plates 4 are opened at the same time, the lifting frame 52 is pushed upward, and the cleaning strip 551 slides in front of the control screen 102, so that the cleaning cotton 552 wipes the surface of the control screen 102 until the top surface of the lifting frame 52 is pressed against the bottom surface of the limit strip 56, and the cleaning strip 551 slides from the bottom of the control screen 102 to the top of the control screen 102, completing a cleaning operation. When the closed cover plates 4 are closed again, the lifting frame 52 descends, and the cleaning strip 551 and the cleaning cotton 552 wipe and clean again, without manual cleaning.

[0074] The automatic conveying assembly 6 includes a conveying bar 61 symmetrically slidably mounted on the outer wall of the ultraviolet box 1, a connecting bar 62 is fixed to the end of the conveying bar 61 away from the ultraviolet box 1, a receiving groove 621 is provided on the top surface of the connecting bar 62 away from the end of the conveying bar 61, an electric push rod 63 is fixed to the end of the connecting bar 62 close to the receiving groove 621, a clamping bar 64 is fixed to the protruding end of the electric push rod 63, the bottom surface of the electric push rod 63 is higher than the bottom surface height of the inner wall of the ultraviolet box 1, a driving rack 65 is fixed to the top of the conveying bar 61, and the driving rack 65 is meshed and connected with the synchronous gear 51, a second accommodating cavity 66 is provided on the outer wall of the ultraviolet box 1, a motor 67 is fixed to the inner wall of the second accommodating cavity 66, a driving gear 68 is fixed to the output end of the motor 67, a conveying rack 69 is fixed to the bottom of the conveying bar 61, and the driving gear 68 is meshed and connected with the conveying rack 69;

[0075] The conveying bar 61 is slidably connected to the outer wall of the UV box 1 through the sliding frame 9. The sliding frame 9 is symmetrically fixed on the outer wall of the UV box 1. The conveying bar 61 is slidably installed on the inner wall of the sliding frame 9. The driving rack 65 follows the sliding process of the conveying bar 61. The driving rack 65 can directly pass through the inner cavity at the upper end of the sliding frame 9.

[0076] When the sample tray 8 is installed, it is inserted into the inner sides of the two receiving grooves 621 and pressed against the inner walls of the receiving grooves 621. Then, the electric push rod 63 is driven to retract, so that the clamping bar 64 clamps the sample tray 8 and fixes the sample tray 8 on the inner walls of the receiving grooves 621. Then, the motor 67 works to drive the driving gear 68 to rotate and toggle the conveying rack 69, thereby pulling the conveying bar 61 to slide along the inner wall of the sliding frame 9, so that the sample tray 8 moves toward the side close to the ultraviolet box 1. At the beginning of the movement, the driving rack 65 moves along and drives the synchronous gear 51 to rotate. It should be emphasized that the driving rack 65 is meshed and connected with the synchronous gear 51 on the side close to the ultraviolet box 1, and the synchronous rack 53 is meshed and connected with the synchronous gear 51 on the side away from the ultraviolet box 1, and the lifting frame 52 and the synchronous rack 53 are located on the side of the conveying bar 61 away from the ultraviolet box 1.

[0077] When the conveying bar 61 clamps the sample tray 8 for loading, the driving rack 65 moves to toggle the synchronous gear 51 to rotate and open the closed cover 4 until the driving rack 65 follows the movement and separates from the synchronous gear 51. At the same time of separation, the two closed cover plates 4 are fully opened, and the top of the lifting frame 52 is pressed against the bottom surface of the limit bar 56. Thereafter, the meshing obstruction of the driving rack 65 is lost, and the two closed cover plates 4 have a sufficiently large gravity to ensure that the lifting frame 52 is always pressed against the bottom surface of the limit bar 56. It should be emphasized that when the lifting frame 52 is just pressed against the bottom surface of the limit bar 56, the closed cover plate 4 just reaches the fully opened state, and the driving rack 65 is just separated from the synchronous gear 51, the sample tray 8 on the conveying bar 61 is as follows. Figure 5 In the position shown, it has not reached the turning trajectory of the closed cover plate 4. The turning trajectory of the closed cover plate 4 is as shown in FIG. Figure 5 The trajectory line AB shown in the figure, therefore, the turning of the closed cover plate 4 will not hinder the movement of the sample tray 8 at all, and then the conveying bar 61 continues to move, and the driving rack 65 follows and slides into the inner cavity of the sliding frame 9, and the sample tray 8 is conveyed to the inner side of the UV box 1, and the sample tray 8 inside the UV box 1 is pushed to unload, until the sample tray 8 on the conveying bar 61 is in place on the support clamp 21, and then the electric push rod 63 rises, and the clamping bar 64 releases the clamping work on the sample tray 8, and then the driving motor 67 is reversed, so that the conveying bar 61 slides to the side away from the UV box 1 and resets, and the friction between the sample tray 8 and the inner wall of the opening 22 of the support clamp 21 is much greater than the friction between it and the inner wall of the accommodating groove 621, so when the conveying bar 61 resets and moves , the sample tray 8 is stably placed in the two support clamps 21, the connecting bar 62 is separated from the sample tray 8, and the conveying bar 61 gradually resets and moves. During the reset movement, the driving rack 65 meshes with the synchronous gear 51 again, and then the conveying bar 61 continues to reset, and the driving rack 65 drives the synchronous gear 51 to rotate, so that the two closed cover plates 4 are flipped and closed at the same time, until the conveying bar 61 is reset, and the driving rack 65 drives the synchronous gear 51 to rotate and press the two closed cover plates 4 against the outer wall of the ultraviolet box 1, completing the closing work of the ultraviolet box 1. At this time, the driving rack 65 is still in a state of meshing with the synchronous gear 51, and then the test work is carried out, and at the same time, the sample tray 8 on the conveying bar 61 is loaded and the glue dispensing and curing work is carried out.

[0078] For example 2, please refer to Fig.18This embodiment provides a further technical solution based on the first embodiment. Protective covers 10 are symmetrically fixed on the outer walls on both sides of the ultraviolet box 1. First through holes 11 are symmetrically opened on the top of the protective cover 10. Both ends of the lifting frame 52 are located in the first through holes 11. Second through holes 12 are symmetrically opened on both sides of the protective cover 10. The conveying bar 61 is located in a second through hole 12 on one side and directly faces a second through hole 12 on the other side. The protective cover 10 covers the transmission parts of the device and can protect them.

[0079] In summary, the present invention can greatly reduce the number of manual operation steps in the light resistance test of polyurethane glue, realize the effects of automatic loading and unloading of the sample tray 8 and automatic peeling of the sample and the sample tray 8, greatly reduce the labor intensity of workers and improve the detection efficiency. At the same time, a cleaning component 55 is also provided, which can automatically complete the cleaning of the control screen 102 while the closed cover 4 is opened and closed, without manual cleaning, further reducing the number of manual operation steps.

[0080] Embodiment 3: Based on Embodiment 1, this embodiment provides a method for using a light resistance testing device for waterproof glue processing, and adopts the above-mentioned light resistance testing device for waterproof glue processing, specifically comprising the following steps:

[0081] A1. The sample tray 8 is inserted into the receiving grooves 621 on the two connecting bars 62, and the electric push rod 63 is retracted so that the clamping bar 64 clamps the sample tray 8 in the receiving groove 621;

[0082] A2, the driving motor 67 rotates to move the conveying rack 69 through the driving gear 68, so that the conveying bar 61 moves with the sample tray 8 toward the UV box 1, and the closed cover 4 is opened synchronously. When the closed cover 4 is opened, the covering component 34 is switched to the exposed state;

[0083] A3, the industrial camera 32 takes a picture of the sample on the sample tray 8 that has finished the test inside the UV box 1 for record;

[0084] A3. The sample tray 8 on the conveying bar 61 continues to move after the photo shooting is finished until the sample tray 8 is inserted into the openings 22 of the two holders 21 and is close to the inner wall of the openings 22 of the holders 21. The electric push rod 63 extends to release the clamping, and the motor 67 reverses to make the conveying bar 61 reset and slide. When the sample tray 8 on the conveying bar 61 is inserted, it pushes the sample tray 8 located on the inner side of the ultraviolet box 1 to unload and the sample and the sample tray 8 are peeled off by the peeling component 23.

[0085] A4. During the sliding process of the conveying bar 61 returning to its original position, the sealing cover plate 4 is closed again. After the conveying bar 61 returns to its original position, the ultraviolet lamp 101 is turned on to perform a light resistance test on the samples in the ultraviolet box 1 .
