Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0046] In order to illustrate the technical solution of the present application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0047] Combination Figures 1 to 5 As shown, in one or more embodiments, the present application provides a curing system for curing the adhesive between automobile door and window glass and a bracket, which includes: a curing chamber 101, a conveying mechanism 102, a steam conveying mechanism 103 and an air supply mechanism 104; the curing chamber 101 has a curing chamber; the conveying mechanism 102 is arranged in the curing chamber, and the conveying mechanism 102 is used to convey the assembled product formed after the automobile door and window glass is bonded to the bracket; the steam conveying mechanism 103 is arranged in the curing chamber, and the steam conveying mechanism 103 is used to provide water vapor into the curing chamber; the air supply mechanism 104 is used to supply air into the curing chamber.

[0048] The curing system provided in the embodiment of the present application utilizes a curing chamber 101 to form a curing chamber, which makes it easy to transport the assembled finished product in the curing chamber; and the steam conveying mechanism 103 can transport water vapor with a higher temperature into the curing chamber. On the one hand, the water vapor can increase the humidity in the curing chamber, and on the other hand, when the water vapor is liquefied, the heat released is beneficial to increase the temperature in the curing chamber. At the same time, the conveying mechanism is used to supply air to the curing chamber to increase the flow of air in the curing chamber, which is beneficial to the curing of the adhesive. Since the assembled finished product is transported in the curing chamber, the temperature and humidity environment in the curing chamber can accelerate the curing and hardening of the adhesive, thereby shortening the curing time of the adhesive, thereby reducing the risks brought by rotation and assembly, improving production efficiency, and ensuring bonding quality.

[0049] In some embodiments, the adhesive used to bond the automobile door and window glass to the bracket can be polyurethane glue; the two ends of the length direction of the curing chamber are respectively the inlet hatch 105 and the outlet hatch 106, and the length direction of the conveying mechanism 102 is parallel to the length direction of the curing chamber, so that the assembled finished product can enter from the inlet hatch 105 and exit from the outlet hatch 106, and the curing chamber can provide it with a sufficient time for accelerated curing environment. When the air supply mechanism 104 supplies air to the curing chamber, the wind speed can be set as needed, and this application does not make specific restrictions. The length of the curing chamber 101 can be 15m to 25m, so that the assembled finished product can have sufficient curing time in the curing chamber, for example, it can be 15m, 20m or 25m. Compared with the curing of polyurethane glue in the related art, which takes 72 hours, the curing time of the polyurethane glue on the assembled finished product of this application is shortened to 2-4 hours after being treated by the curing system, which promotes the rapid hardening of the polyurethane glue and meets the bonding strength required by the production process.

[0050] Combination Figure 4 and Figure 5 As shown, in some embodiments, the curing system further includes a bracket 107, the bracket 107 is installed in the curing chamber, and the steam conveying mechanism 103 is installed on the bracket 107. This facilitates the installation of the steam conveying mechanism 103. Exemplarily, the bracket 107 includes a plurality of legs 108 and a top frame 109, and the plurality of legs 108 are arranged around the circumference of the top frame 109; the legs 108 are fixedly connected to the top frame 109, and the legs 108 are used to support the top frame 109. In the height direction of the bracket 107, the top frame 109 is located above the conveying mechanism 102, so that the steam conveying mechanism 103 can convey water vapor to the assembled finished product conveyed on the conveying mechanism 102.

[0051] Combination Figures 5 to 8 As shown, in some embodiments, the steam delivery mechanism 103 includes a steam generator 110 and a delivery pipe 111. The steam generator 110 is connected to the delivery pipe 111. Water vapor is generated by the steam generator 110. The generated water vapor enters the delivery pipe 111 and is delivered to a preset position in the curing chamber along the delivery pipe 111.

[0052] Combination Figures 5 to 8As shown, in some embodiments, the delivery pipeline 111 includes a first pipeline 112 and a second pipeline 113; in the height direction of the bracket 107, the first pipeline 112 is located above the second pipeline 113, the first pipeline 112 is configured to be located above the assembled product, and the second pipeline 113 is configured to be located below the assembled product, and the length direction of the first pipeline 112 is parallel to the length direction of the second pipeline 113; a plurality of first discharge ports 114 are arranged at intervals on the first pipeline 112, and the first discharge ports 114 are arranged to face the assembled product; a plurality of second discharge ports 115 are arranged at intervals on the second pipeline 113, and the angle formed between the direction of the second discharge ports 115 and the direction of the first discharge ports 114 is a right angle. In this way, water vapor can be provided above and below the assembled product, so that most or all of the adhesive on the assembled product can be in the water vapor environment, so that the use of water vapor can achieve the internal and external curing of the adhesive, improve the curing speed and curing quality, and avoid or reduce the phenomenon that only the surface of the adhesive is cured.

[0053] Combination Figures 5 to 8 As shown, exemplarily, the length direction of the first pipe 112 and the length direction of the second pipe 113 are both parallel to the length direction of the conveying mechanism 102, so that the first pipe 112 and the second pipe 113 are laid along the conveying direction of the conveying mechanism 102, so as to realize that the assembled finished products on the conveying mechanism 102 are in a suitable curing environment during the conveying process. The radial cross section of the second pipe 113 can be rectangular or circular. The first pipe 112 includes a main pipe 116 and a plurality of branch pipes 117, and the plurality of branch pipes 117 are evenly spaced along the length direction of the main pipe 116, and the branch pipes 117 are connected to the main pipe 116; the first outlet 114 is the outlet of the free end of the branch pipe 117. The length direction of the first pipe 112 is the length direction of the main pipe 116. The radial cross section of the main pipe 116 can be rectangular or circular; the radial cross section of the branch pipe 117 can be rectangular or circular, and the radial cross section of the main pipe 116 matches the radial cross section of the branch pipe 117. The length of the main pipeline 116 extends in a straight line, and the length of the second pipeline 113 extends in a straight line. By using the branch pipe 117, the water vapor can be discharged closer to the assembled finished product, so as to increase the curing speed.

[0054] Combination Figures 5 to 8As shown, in some embodiments, the delivery pipeline 111 also includes a horizontal pipeline 118 and a vertical pipeline 119, and the length direction of the horizontal pipeline 118 is perpendicular to the length direction of the first pipeline 112; the length direction of the horizontal pipeline 118 is perpendicular to the length direction of the vertical pipeline 119; the length direction of the vertical pipeline 119 is perpendicular to the length direction of the second pipeline 113; the length direction of the first pipeline 112 and the length direction of the horizontal pipeline 118 are respectively parallel to the first plane; the length direction of the vertical pipeline 119 and the length direction of the second pipeline 113 are respectively parallel to the second plane; the first plane is perpendicular to the second plane. In this way, the orthographic projection of the first pipeline 112 in the first plane is realized, and the orthographic projection of the second pipeline 113 in the first plane is arranged at intervals, which is conducive to the water vapor discharged from the second pipeline 113 and the water vapor discharged from the first pipeline 112 being discharged from different angles, so that the adhesive on the assembled finished product can be cured faster. Exemplarily, the length of the horizontal pipeline 118 extends along a straight line, and the length of the vertical pipeline 119 extends along a straight line; the first plane is perpendicular to the height direction of the bracket 107. The length of the main pipe 116 can be 15m to 18m, and the length of the second pipe 113 can be 15m to 19m; the length of the main pipe 116 is less than or equal to the length of the second pipe 113. The length of the second pipe 113 is less than the length of the conveying mechanism 102, so that the temperature of the assembled finished product can be cooled within a set length range close to the conveying end of the conveying mechanism 102, which is beneficial to the curing and curing quality of the adhesive.

[0055] Combination Figures 5 to 8 As shown, in some embodiments, the steam delivery mechanism 103 also includes a water storage barrel 120, and the water storage barrel 120 is connected to the steam generator 110. Exemplarily, water is stored in the water storage barrel 120, and the steam generator 110 can absorb the water in the water storage barrel 120 and generate water vapor. The curing system also includes an alarm, which can be an alarm light or a buzzer. A liquid level gauge can be installed on the water storage barrel 120. When the water level in the water storage barrel 120 reaches the alarm line, an alarm can be issued through the alarm to prompt timely water addition. The water storage barrel 120 can be arranged on the top bracket 107. Of course, in some other possible embodiments, the water storage barrel 120 can also be arranged outside the curing cabin 101.

Exemplarily, the first fan 130 can be an axial flow fan, and the second fan 131 can be an axial flow fan.

[0057] In some embodiments, the conveying mechanism 102 is a belt conveyor, a roller conveyor or a chain conveyor, so that different types of conveying mechanisms 102 can be selected according to different needs. For example, the conveying speed of the conveying mechanism can be set according to needs, and it is only necessary to ensure that each assembled finished product enters the curing chamber from the hatch entrance to the hatch exit, and the total length of time that the assembled finished product stays in the curing chamber is 2 to 4 hours, so that the inside and outside of the adhesive can be cured; for example, the total length of time that stays can be 2 hours, 3 hours or 4 hours, which is not specifically limited in this application.

[0058] In some embodiments, there are two steam conveying mechanisms 103, which are symmetrically arranged, so that the curing and hardening speed of the adhesive can be increased and the curing quality can be improved. There are two conveying mechanisms 102, which are symmetrically arranged, and the two steam conveying mechanisms 103 are arranged one-to-one with the two conveying mechanisms 102, so that the production efficiency can be improved.

[0060] In some embodiments, the curing system further includes a heating device, and the heating device is disposed in the curing chamber. For example, the heating device may be a heating wire, so that the first fan can draw air heated by the heating wire into the curing chamber. The heating wire may be disposed close to the first fan. It should be noted that, in some other possible implementations, a cold air device may also be disposed at the end of the second pipe in the curing chamber, so that the assembled finished product can be gradually cooled within the distance from the end of the second pipe to the hatch outlet; the air outlet of the cold air device faces the hatch outlet.
