Description

Technical Field

[0001] This utility model relates to the field of glass glue testing technology, specifically a glass glue finished product testing device. Background Technology

[0002] Glass sealant is an elastic sealing material made primarily of organosilicon polymers (such as polydimethylsiloxane), with added fillers, crosslinking agents, catalysts, etc. During the processing of finished glass sealant products, it is usually tested, such as physical performance testing (extrudability, surface drying time, tensile strength, etc.) and chemical performance testing (composition analysis, weather resistance testing, etc.). Among them, the surface drying test of glass sealant refers to the stage in which the surface of the sealant gradually dries from a wet state to form a "skin" (usually defined as not sticky to the touch with a finger). At this time, the surface humidity drops significantly. If the surface drying time is too short, it will easily lead to poor leveling of the sealant and surface cracking. If it is too long, it will prolong the construction period and increase the risk of pollution.

[0003] However, traditional methods for testing the surface dryness of silicone sealant rely on finger touch or cotton ball methods, requiring personnel to periodically observe the surface condition of the sealant. This makes it impossible to achieve sealant application and humidity monitoring in a constant temperature and humidity environment. When testing silicone sealant, temperature and humidity fluctuations can cause the test data to deviate from reality, resulting in significant errors. Furthermore, in the traditional method of testing the surface dryness time of silicone sealant, workers need to squeeze the silicone sealant into strips onto a placement plate. However, due to the influence of force, it is easy to cause poor coating uniformity, with inconsistent thickness and width. The greater the thickness, the longer the path for internal moisture to migrate to the surface, and the longer the surface dryness time. If it is too thin, the moisture at the edges may evaporate quickly, causing a "false dryness" phenomenon. Utility Model Content

[0004] To address the issues that current testing methods for surface dryness of silicone sealant cannot perform dynamic monitoring under constant temperature and humidity conditions, and that silicone sealant is easily affected by the extrusion force applied by workers, making it difficult to accurately reflect the actual surface dryness data, the purpose of this invention is to provide a silicone sealant finished product testing device.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a glass glue finished product testing device, including a constant temperature and humidity chamber, a reciprocating screw is rotatably mounted on the upper part of the constant temperature and humidity chamber, a drive assembly is provided on one side of the reciprocating screw, the drive assembly includes a mounting frame, the mounting frame is fixedly mounted on the upper side of the constant temperature and humidity chamber, a motor is fixedly mounted on the top of the mounting frame, one end of the reciprocating screw is fixedly mounted on the drive end of the motor, a movable block that cooperates with each other is mounted on the upper part of the reciprocating screw, a fixed plate is fixedly mounted on the bottom end of the movable block, and two... The chamber features symmetrically distributed dispensing pipes. A placement plate is located on the lower internal surface of the temperature and humidity chamber. Two symmetrically distributed infrared humidity sensors are detachably installed on the upper internal surface of the chamber. Symmetrically distributed dispensing pumps are fixedly installed on one side of the top of the chamber. The output ends of the two dispensing pumps are connected to the input ends of the dispensing pipes via flexible hoses. A human-machine interface device is fixedly installed on one side of the chamber. A mounting frame is fixedly installed in the middle of the chamber. Two symmetrically distributed limiting blocks are rotatably mounted on the upper part of the mounting frame, with one end of each limiting block contacting the top of the placement plate.

[0006] Preferably, a sliding rod is slidably mounted in the middle of the fixing frame, a pushing block is fixedly installed at the top of the sliding rod, and grooves are opened in the middle of both sides of the pushing block. Rotating rods are fixedly installed on both sides of the two limiting blocks, and the two rotating rods are slidably mounted inside the grooves.

[0007] Preferably, a slider is fixedly installed at the top of the moving block, a groove is opened on the inner upper surface of the constant temperature and humidity chamber, the slider is slidably locked inside the groove, threaded connectors are fixedly installed at the input ends of the two glue pumps, two symmetrically distributed handles are fixedly installed at the top center of the placement plate, a spring is fixedly installed at the top center of the fixed frame, the top of the spring is fixedly installed at the bottom of the push block, a cavity is opened in the middle of the constant temperature and humidity chamber, and the sliding rod is slidably locked inside the cavity.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. This application uses a motor-driven reciprocating screw to move the glue dispensing pipe, which can uniformly extrude and apply the glass glue onto the placement plate. This avoids the inconsistent thickness and width of the strip glass glue caused by manual extrusion, resulting in different surface drying times and affecting the test results. At the same time, through the cooperation of springs and limit blocks, the placement plate for placing glass glue can be quickly loaded and unloaded, significantly improving the batch testing efficiency of the production line.

[0010] 2. By setting up a constant temperature and humidity chamber and an infrared humidity sensor, this application can ensure that the glass sealant is always tested in a relatively stable temperature and humidity environment, thereby making the test data more accurate. At the same time, the infrared humidity sensor can collect and monitor the humidity of the outer surface of the glass sealant in real time. When the humidity curve tends to flatten and is lower than the preset threshold, the timing is automatically triggered to stop, thereby reducing the error caused by manual judgment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-4As shown, this utility model provides a glass glue finished product testing device, including a constant temperature and humidity chamber 1. A reciprocating screw 35 is rotatably mounted on the upper part of the constant temperature and humidity chamber 1. A driving assembly is provided on one side of the reciprocating screw 35. A movable block 36 that works in conjunction with the reciprocating screw 35 is installed on the upper part of the reciprocating screw 35. A fixing plate 32 is fixedly installed at the bottom end of the movable block 36. Two sets of symmetrically distributed glue outlet pipes 33 are fixedly installed on the lower part of the fixing plate 32. A placement plate 2 is provided on the lower inner surface of the constant temperature and humidity chamber 1. Two symmetrically distributed infrared humidity sensors 37 are detachably installed on the upper inner surface of the constant temperature and humidity chamber 1. By setting the infrared humidity sensors 37, the device can... By utilizing the absorption characteristics of water molecules to infrared light of a specific wavelength, the moisture content of the adhesive surface can be indirectly determined by detecting changes in the intensity of infrared light reflected or transmitted from the surface of the glass adhesive, thereby assessing the degree of surface dryness. A symmetrically distributed adhesive pump 3 is fixedly installed on one side of the top of the constant temperature and humidity chamber 1. The output ends of the two adhesive pumps 3 are connected to the input end of the adhesive outlet pipe 33 through hoses. A human-machine control device 4 is fixedly installed on one side of the constant temperature and humidity chamber 1. A fixed frame 22 is fixedly installed in the middle of the constant temperature and humidity chamber 1. Two symmetrically distributed limiting blocks 25 are rotatably installed on the upper part of the fixed frame 22. One end of the two limiting blocks 25 is in contact with the top of the placement plate 2.

[0019] The fixed frame 22 has a sliding rod 24 in the middle, and a push block 23 is fixedly installed at the top of the sliding rod 24. The push block 23 has a groove 252 in the middle of both sides. Rotating rods 251 are fixedly installed on both sides of the two limiting blocks 25, and the two rotating rods 251 are slidably locked inside the groove 252.

[0020] The drive assembly includes a mounting bracket 341, which is fixedly installed on the upper side of the constant temperature and humidity chamber 1. A motor 34 is fixedly installed on the top of the mounting bracket 341, and one end of the reciprocating lead screw 35 is fixedly installed on the drive end of the motor 34. By setting the motor 34, the reciprocating lead screw 35 can be driven to rotate under the drive of the motor 34.

[0021] A slider is fixedly installed at the top of the movable block 36. A groove is provided on the upper surface of the constant temperature and humidity chamber 1. The slider is slidably locked inside the groove. By setting the slider and the groove, the slider installed on the upper part of the movable block 36 is slidably locked inside the groove, thereby limiting the movable block 36 and ensuring that the movable block 36 can be driven to reciprocate under the rotation of the reciprocating screw 35, without rotating along with it.

[0022] Both of the glue extraction pumps 3 have threaded connectors 31 fixedly installed at their input ends. By setting the threaded connectors 31, the glue extraction pumps 3 and the output ends of the glass glue storage container can be easily connected to each other through the threaded connection.

[0023] Two symmetrically distributed handles 21 are fixedly installed at the top center of the placement plate 2. By setting the handles 21, it is convenient for staff to take the placement plate 2 out of the constant temperature and humidity chamber 1.

[0024] A spring 26 is fixedly installed at the top center of the fixed frame 22. The top of the spring 26 is fixedly installed at the bottom of the push block 23. By setting the spring 26, the push block 23 can be reset under the action of the spring 26, so that its two limiting blocks 25 limit and fix the placement plate 2.

[0025] The constant temperature and humidity chamber 1 has a cavity 241 in the middle. The sliding rod 24 is slidably locked inside the cavity 241. By setting the cavity 241, the sliding rod 24 can slide inside the cavity 241, thereby ensuring that the up and down movement of the push block 23 is not affected.

[0026] Working principle: When conducting a surface drying test on the finished glass glue, the container containing the finished glass glue is connected to the glue pump 3 through the threaded connector 31. At this time, the glue pump 3 is started to extract the glass glue from the container. Under the delivery of the hose, the glass glue is squeezed out through the glue outlet pipe 33. At the same time, the motor 34 is started. Under the drive of the motor 34, the reciprocating screw 35 is rotated, which drives the moving block 36 that works with it to move forward, thereby squeezing the glass glue evenly on the upper surface of the placement plate 2, so that the glass glue is distributed in strips on the upper surface of the placement plate 2.

[0027] After extrusion is complete, the glue pump 3 stops working, while the motor 34 continues to drive. Through the cooperation of the reciprocating screw 35 and the moving block 36, the glue outlet pipe 33 is reset. At this time, the infrared humidity sensor 37 inside the constant temperature and humidity chamber 1 is activated to monitor the change of surface humidity of the extruded glass glue over time in real time and determine whether the surface drying threshold has been reached. If the surface drying threshold is reached, the feedback module will send a message to the human-machine control device 4. At this time, the human-machine control device 4 will stop timing and remind the staff to check and inspect the surface drying status of the glass glue.

[0028] After the test, the staff holds the handle 21 and presses down the push block 23, causing the compression spring 26 to simultaneously move the two limit blocks 25 downwards, so that the two ends of the two limit blocks 25 that are in contact with the placement plate 2 are away from the placement plate 2. At this time, the placement plate 2 can be pulled upwards to remove it from the inside of the constant temperature and humidity chamber 1. During installation, the same steps are followed: first, press down the push block 23 and then pass the placement plate 2 through the limit block 25 and place it inside the constant temperature and humidity chamber 1. At this time, the push block 23 is released, and under the reaction action of the spring 26, the push block 23 is reset, so that the two limit blocks 25 are in contact with the placement plate 2, that is, they are limited and fixed.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
