This equipment typically consists of an applicator, a conveying system, and a control system. Automatic glass adhesive application equipment has a wide range of applications, including glass manufacturing, construction, and the automotive industry. However, current automatic glass adhesive application equipment cannot automatically increase the adhesive's viscosity upon startup and cannot remove dust or debris from the object being coated. Summary of the Invention

[0007] Preferably, the clamping component includes a first slide rail, a clamp, and glass. The first slide rail is fixedly installed on the top of the support, the clamp is slidably installed on the top of the first slide rail, and the clamp is electrically connected to the support.

[0008] Preferably, the movable component includes a U-shaped movable support rod, a movable element, and a teach pendant. The movable support rod is fixedly installed on the top of the end of the support body away from the control panel, the movable element is installed on the side wall of the movable support rod, and the teach pendant is installed at the end of one end of the movable support rod.

[0009] Preferably, the movable component includes a second slide rail, a slider, an inverted L-shaped movable block, and a movable belt. The second slide rail is fixedly installed on the side wall of one side of the movable support rod, the slider is slidably installed in the second slide rail, the side wall at the lower end of the movable block is fixedly connected to the slider, and the movable belt is installed on the side wall of the other side of the movable support rod, and the movable belt is fixedly connected to the upper end of the movable block.

[0010] Preferably, the air pump assembly includes a control component and an air pump component. The control component is fixedly installed at the end of the other end of the movable support rod, and the air pump component moves along the side wall of the support rod. The air pump component and the control component are electrically connected.

[0011] Preferably, the control component includes a control body, a pressure gauge, a pressure adjustment knob, and a pressure switching power supply. The control body is fixedly installed at one end of the movable support rod, the pressure gauge is fixedly installed at the upper end of the side wall of the control body, the pressure adjustment knob is installed in the middle of the side wall of the control body, and the pressure switching power supply is installed at the lower end of the side wall of the control body.

[0012] Preferably, the glue application assembly includes a fixing component, a glue bucket, and a glue dispensing pipe. The fixing component is fixedly installed on the side wall of the movable block, the glue bucket is inserted into the fixing component and contains glue, the glue dispensing pipe is installed at the bottom of the glue bucket, the preheating body is installed inside the glue bucket, and the top of the glue bucket is connected to the air pump component through an air pipe.

[0013] Preferably, the tensioning component includes a shape memory alloy and a tension spring. The upper end of the shape memory alloy is fixedly connected to the bottom of the fixed rod, the upper end of the tension spring is fixedly connected to the lower end of the shape memory alloy, and the lower end of the tension spring is fixedly connected to the friction plate.

[0014] The present invention also provides an automatic adhesive application method for glass, comprising the following steps:

[0015] Step S1: Clamp the glass onto the fixture, adjust the pressure of the control component, start the first switch of the support component, the fixture clamps the glass and moves it downward toward the moving support rod, the moving belt drives the moving block and slider to move toward one side of the fixture, when the glue application component reaches above the glass, the glue application component moves downward to apply glue to the glass.

[0016] Step S2: As the dispensing tube moves toward the glass, the air pump applies pressure to the glue container, squeezing the glue out of the dispensing tube. While the air pump applies pressure to the glue container, it also blows air into the preheating body. The airflow blown out by the air pump enters the preheating body and forms a pushing airflow F1. When the pushing airflow F1 pushes against the friction plate, part of the airflow accumulates between the friction plate and the air pump. The pushing airflow F1 pushes the friction plate downward, stretching the spring and allowing the friction plate to rub downward against the wall of the preheating body, thereby generating heat. The generated heat is used to heat the glue inside the glue container. Another part enters the next preheating structure through the air outlet. The pushing airflow F1 in the next preheating structure similarly causes the friction plate of the next preheating structure to rub against the wall of the preheating body, thereby generating heat. The generated heat is used to heat the glue inside the glue container.

[0017] Step S3: After the adhesive is applied to the glass, the adhesive application assembly moves upward, the control unit closes, the air pump stops applying pressure, the adhesive returns to the glue bucket, and the air pump stops blowing air into the preheating body. The pushing airflow F1 finally flows out from the air outlet of the glue dispensing preheating structure, the tension spring returns to its original position, and the friction plate rubs upward against the wall of the preheating body, causing the wall of the preheating body to generate heat. The generated heat is used to heat the adhesive inside the glue bucket. After moving to the next adhesive application position, the control unit of the air pump assembly will start, and the cycle continues until the adhesive application is completed.

[0018] Step S4: After the adhesive is applied to the adhesive assembly for a period of time, the wall temperature of the preheating body rises, the temperature of the adhesive inside the adhesive bucket rises, and the shape memory alloy of the dispensing preheating structure will be heated and contracted, so that the position of the friction plate rubbing the preheating body becomes higher, and there is no need to rub the outlet end of the dispensing tube to raise the temperature in advance. At the same time, the pushing airflow F1 that finally flows out of the air outlet of the dispensing preheating structure can also blow away the dust adhering to the glass.

[0019] This invention incorporates a preheating component. As the glue dispensing tube moves towards the glass, the air pump assembly's control unit activates, pressurizing the glue container and forcing the glue out through the dispensing tube. Simultaneously, the air pump blows air into the preheating body, forming a pushing airflow F1. This F1 moves towards the dispensing tube. When it hits the friction plate, some of the airflow accumulates between the friction plate and the air pump, while the rest flows through the vent into the next preheating structure. The flow rate into the next preheating structure through the vent is less than the airflow blown out by the air pump, increasing the amount of pushing airflow F1 accumulated between the friction plate and the air pump. This allows the pushing airflow F1 to push the friction plate downwards, stretching the spring and causing the friction plate to rub against the wall of the preheating body, generating heat. This heat is used to heat the glue inside the glue container, preventing it from solidifying and making it easier to apply to the glass. The pushing airflow F1 enters the next preheating structure, causing the friction plate of the next preheating structure to rub against the wall of the preheating body, thereby generating heat. This heat is used to heat the adhesive inside the glue bucket, preventing it from solidifying. After the adhesive is applied to the glass, the application assembly moves upward, the control unit closes, the air pump stops applying pressure, and the adhesive returns to the glue bucket. Simultaneously, the air pump stops blowing air onto the preheating body, and the pushing airflow F1 finally flows out from the air outlet of the glue dispensing preheating structure. The tension spring returns to its original position, and the friction plate rubs upward against the wall of the preheating body, generating heat on the wall. This heat is used to heat the adhesive inside the glue bucket, preventing it from solidifying and making it easier to apply to the glass. After moving to the next application position, the control unit of the air pump assembly will activate, continuing the cycle until the application is complete. By incorporating a shape memory alloy, after the adhesive application assembly has been in place for a period of time, the wall temperature of the preheating body rises, and the temperature of the adhesive inside the glue tank also rises. The shape memory alloy in the dispensing preheating structure contracts due to heat, causing the friction plate to rub against the preheating body at a higher position. This eliminates the need to preheat the outlet end of the dispensing tube, preventing excessively high outlet temperatures that could lead to overheating of the adhesive and reduced viscosity. Simultaneously, the pushing airflow F1 exiting from the vent of the dispensing preheating structure can disperse dust adhering to the glass, preventing adhesive from being applied to the dust and thus reducing adhesive viscosity. This invention has a clever structure that effectively improves adhesive viscosity while simultaneously cleaning dust from the object being glued, preventing adhesive from being applied to dust and thus reducing adhesive viscosity.

The movable belt 27 is installed on the side wall of the other side of the movable support rod 21, and the movable belt 27 is fixedly connected to the upper end of the movable block 26.

[0035] like Figures 1 to 3 As shown, the air pump assembly 30 includes a control component 31 and an air pump component 32. The control component 31 is fixedly installed at the end of the other end of the movable support rod 21, and the air pump component 32 moves the side wall of the support rod 21.

[0036] like Figures 1 to 3 As shown, the control unit 31 includes a control body 33, a pressure gauge 34, a pressure adjustment knob 35, and a pressure switching power supply 36.

The fixing member 41 is fixedly installed on the side wall of the movable block 26. The glue tank 42 is inserted into the fixing member 41 and contains glue. The glue dispensing pipe 43 is installed at the bottom of the glue tank 42. The preheating body 51 is installed inside the glue tank 42.

[0038] like Figure 4 and Figure 5 As shown, the tension member 56 includes a shape memory alloy 560 and a tension spring 561. The upper end of the shape memory alloy 560 is fixedly connected to the bottom of the fixed rod 55, the upper end of the tension spring 561 is fixedly connected to the lower end of the shape memory alloy 560, and the lower end of the tension spring 561 is fixedly connected to the friction plate 57.

[0039] The present invention also provides an automatic adhesive application method for glass, comprising the following steps:

[0040] Step S1: Clamp the glass 19 onto the clamp 18, adjust the pressure of the control component 31, and start the first switch 16 of the support component 11. The clamp 18 clamps the glass 19 and moves it downward toward the moving support rod 21. The moving belt 27 drives the moving block 26 and the slider 25 to move toward one side of the clamp 18. When the glue application component 40 reaches above the glass 19, the glue application component 40 moves downward to apply glue to the glass 19.

[0041] Step S2: As the dispensing tube 43 moves toward the glass 19, the air pump 32 applies pressure to the glue container 42, squeezing the glue in the container 42 out of the dispensing tube 43. While the air pump 32 applies pressure to the glue container 42, it can also blow air into the preheating body 51. The airflow blown out by the air pump 32 enters the preheating body 51 to form a pushing airflow F1. When the pushing airflow F1 pushes against the friction plate 57, a portion of the airflow accumulates between the friction plate 57 and the air pump 32. The plate 57 moves downward, stretching the spring 561, so that the friction plate 57 can rub downward against the wall of the preheating body 51, thereby generating heat. The generated heat is used to heat the glue inside the glue bucket 42, and another part enters the next preheating structure 53 through the air outlet 570, entering the pushing airflow F1 of the next preheating structure 53. Similarly, the friction plate 57 of the next preheating structure 53 rubs against the wall of the preheating body 51, thereby generating heat. The generated heat is used to heat the glue inside the glue bucket 42.

[0042] Step S3: After the adhesive is applied to the glass 19, the adhesive application assembly 40 moves upward, the control component 31 closes, the air pump component 32 stops applying pressure, the adhesive returns to the glue tank 42, and at the same time the air pump component 32 stops blowing air into the preheating body 51. The pushing airflow F1 finally flows out from the air outlet 570 of the glue dispensing preheating structure 54, the tension spring 561 returns to its original state, and the friction plate 57 rubs upward against the wall of the preheating body 51, so that the wall of the preheating body 51 generates heat. The generated heat is used to heat the adhesive inside the glue tank 42. After moving to the next adhesive application position, the control component 31 of the air pump assembly 30 will be activated, and the cycle continues until the adhesive application is completed.

[0043] Step S4: After applying adhesive to the adhesive assembly 40 for a period of time, the wall temperature of the preheating body 51 rises, the temperature of the adhesive inside the adhesive bucket 42 rises, and the shape memory alloy 560 of the dispensing preheating structure 54 will shrink due to heat, so that the position of the friction plate 57 rubbing the preheating body 51 becomes higher. It is not necessary to rub the outlet end of the dispensing tube 43 in advance to prevent the temperature of the outlet end of the dispensing tube 43 from being too high, which would reduce the viscosity of the adhesive. It also leaves a distance to provide the adhesive at the outlet end for slow cooling. At the same time, the pushing airflow F1 that finally flows out from the air outlet 570 of the dispensing preheating structure 54 can also blow away the dust adhering to the glass 19.

[0044] During installation: The movable component 20 is installed on the top end of the support component 10, the air pump component 30 is installed on one end of the movable component 20, the glue application component 40 is installed on the side wall of the movable component 20, the preheating mechanism 50 is installed inside the glue application component 40, the preheating body 51 is installed inside the glue application component 40, all four preheating components 52 are installed inside the preheating body 51, and multiple preheating structures 53 and glue dispensing preheating structure 54 are installed inside the preheating body 51. The fixing rod 55 is fixedly installed inside the preheating body 51, the clamp 12 is fixedly installed on the top of the support component 11, the emergency stop button 15 is installed on one end of the side wall of the operation panel 14, the first switch 16 is installed on the other end of the side wall of the operation panel 14, the first slide rail 17 is fixedly installed on the top of the support body 13, and the clamp 18 is slidably installed on the top of the first slide rail 17. The movable support rod 21 is fixedly installed on the top of the support body 13 at the end away from the operation panel 14. The movable part 22 is installed on the side wall of the movable support rod 21. The teaching pendant 23 is installed at the end of one end of the movable support rod 21. The second slide rail 24 is fixedly installed on the side wall of one side of the movable support rod 21. The slider 25 is slidably installed in the second slide rail 24. The moving belt 27 is installed on the side wall of the other side of the movable support rod 21. The control part 31 is fixedly installed at the end of the other end of the movable support rod 21. The control body 33 is fixedly installed at one end of the movable support rod 21. The pressure gauge 34 is fixedly installed on the upper end of the side wall of the control body 33. The pressure adjustment knob 35 is installed in the middle of the side wall of the control body 33. The pressure switch power supply 36 is installed at the lower end of the side wall of the control body 33. The fixing part 41 is fixedly installed on the side wall of the moving block 26. The dispensing tube 43 is installed at the bottom of the glue tank 42. The preheating body 51 is installed inside the glue tank 42.

[0045] In use: 1. Clamp the glass 19 onto the clamp 18, adjust the pressure of the control component 31, and start the first switch 16 of the support component 11. The clamp 18 clamps the glass 19 and moves it downward toward the moving support rod 21. The moving belt 27 drives the moving block 26 and the slider 25 to move toward one side of the clamp 18. When the glue application component 40 reaches above the glass 19, the glue application component 40 moves downward to apply glue to the glass 19.

[0046] 2. As the dispensing tube 43 moves toward the glass 19, the control unit 31 of the air pump assembly 30 will be activated, causing the air pump 32 to apply pressure to the glue tank 42, and the glue in the glue tank 42 will be squeezed out from the dispensing tube 43. When the air pump 32 applies pressure to the glue container 42, it can also blow air into the preheating body 51. The airflow blown out by the air pump 32 enters the preheating body 51 and forms a pushing airflow F1. The pushing airflow F1 moves toward the glue outlet pipe 43. When the pushing airflow F1 pushes against the friction plate 57, part of the airflow accumulates between the friction plate 57 and the air pump 32, and the other part enters the next preheating structure 53 through the air outlet 570. The speed at which the airflow flows into the next preheating structure 53 through the air outlet 570 is less than the airflow blown out by the air pump 32, which increases the amount of pushing airflow F1 accumulated between the friction plate 57 and the air pump 32. This allows the pushing airflow F1 to push the friction plate 57 downward, and the tension spring 561 to stretch, so that the friction plate 57 can rub downward against the wall of the preheating body 51, thereby generating heat. The generated heat is used to heat the glue inside the glue container 42, preventing the glue from solidifying, and making it easier to apply to the glass 19. The pushing airflow F1 enters the next preheating structure 53, causing the friction plate 57 of the next preheating structure 53 to rub against the wall of the preheating body 51, thereby generating heat. The generated heat is used to heat the glue inside the glue tank 42, preventing the glue from solidifying. After the glue is applied to the glass 19, the glue application assembly 40 moves upward, the control component 31 closes, the air pump component 32 stops applying pressure, and the glue returns to the glue tank 42. At the same time, the air pump component 32 stops blowing air into the preheating body 51, and the pushing airflow F1 finally flows out from the air outlet 570 of the glue dispensing preheating structure 54. The tension spring 561 returns to its original position, and the friction plate 57 rubs upward against the wall of the preheating body 51, causing the wall of the preheating body 51 to generate heat. The generated heat is used to heat the glue inside the glue tank 42, preventing the glue from solidifying, and making it easier to apply to the glass 19. After moving to the next glue application position, the control component 31 of the air pump assembly 30 will be activated, and the cycle will continue until the glue application is completed.

[0047] 3. The dispensing tube 43 includes an inlet end (not shown in the figure) and an outlet end (not shown in the figure). The inlet end is installed at the bottom of the glue tank 42, and the outlet end is connected to the inlet end. After the glue is applied by the glue application assembly 40 for a period of time, the wall temperature of the preheating body 51 rises, and the temperature of the glue inside the glue tank 42 rises. The shape memory alloy 560 of the dispensing preheating structure 54 will shrink due to heat, which makes the position of the friction plate 57 rubbing against the preheating body 51 higher. It is not necessary to rub the outlet end of the dispensing tube 43 in advance to prevent the outlet end temperature from being too high, which would cause the glue temperature to be too high and reduce the viscosity of the glue. At the same time, the pushing airflow F1 that finally flows out from the air outlet 570 of the dispensing preheating structure 54 can also blow away the dust adhering to the glass 19, preventing the glue from being applied to the dust on the glass 19 and causing the glue viscosity to decrease.

[0048] 4. Each friction plate 57 is also equipped with a first conductive heating element on its side wall. The first conductive elements are electrically connected to the air pump component 32. A second conductive heating element is installed below each first conductive element. The second conductive heating element is installed inside the preheating body 51. When the friction plate 57 moves downward, the first conductive heating element and the second conductive heating element will come into contact and conduct electricity, so that the first conductive heating element and the second conductive heating element heat up, thereby further increasing the temperature of the side wall of the preheating body 51, and thus increasing the temperature of the adhesive.

[0049] By setting up a preheating component 52, the control component 31 of the air pump component 30 will be activated while the glue dispensing tube 43 moves toward the glass 19, so that the air pump component 32 applies pressure to the glue tank 42, and the glue in the glue tank 42 is squeezed out from the glue dispensing tube 43. When the air pump 32 applies pressure to the glue container 42, it can also blow air into the preheating body 51. The airflow blown out by the air pump 32 enters the preheating body 51 and forms a pushing airflow F1. The pushing airflow F1 moves toward the glue outlet pipe 43. When the pushing airflow F1 pushes against the friction plate 57, part of the airflow accumulates between the friction plate 57 and the air pump 32, and the other part enters the next preheating structure 53 through the air outlet 570. The speed at which the airflow flows into the next preheating structure 53 through the air outlet 570 is less than the airflow blown out by the air pump 32, which increases the amount of pushing airflow F1 accumulated between the friction plate 57 and the air pump 32. This allows the pushing airflow F1 to push the friction plate 57 downward, and the tension spring 561 to stretch, so that the friction plate 57 can rub downward against the wall of the preheating body 51, thereby generating heat. The generated heat is used to heat the glue inside the glue container 42, preventing the glue from solidifying, and making it easier to apply to the glass 19. The pushing airflow F1 enters the next preheating structure 53, causing the friction plate 57 of the next preheating structure 53 to rub against the wall of the preheating body 51, thereby generating heat. The generated heat is used to heat the glue inside the glue tank 42, preventing the glue from solidifying. After the glue is applied to the glass 19, the glue application assembly 40 moves upward, the control component 31 closes, the air pump component 32 stops applying pressure, and the glue returns to the glue tank 42. At the same time, the air pump component 32 stops blowing air into the preheating body 51, and the pushing airflow F1 finally flows out from the air outlet 570 of the glue dispensing preheating structure 54. The tension spring 561 returns to its original position, and the friction plate 57 rubs upward against the wall of the preheating body 51, causing the wall of the preheating body 51 to generate heat. The generated heat is used to heat the glue inside the glue tank 42, preventing the glue from solidifying, and making it easier to apply to the glass 19. After moving to the next glue application position, the control component 31 of the air pump assembly 30 will be activated, and the cycle will continue until the glue application is completed. By incorporating a shape memory alloy 560, after the adhesive is applied to the coating assembly 40 for a period of time, the wall temperature of the preheating body 51 rises, and the temperature of the adhesive inside the glue tank 42 rises. The shape memory alloy 560 in the dispensing preheating structure 54 will shrink due to heat, causing the friction plate 57 to rub the preheating body 51 at a higher position. This eliminates the need to preheat the outlet end of the dispensing tube 43, preventing excessively high outlet temperatures that could lead to overheating of the adhesive and reduced viscosity. Simultaneously, the pushing airflow F1 exiting from the vent 570 of the dispensing preheating structure 54 can also disperse dust adhering to the glass 19, preventing adhesive from being applied to the dust and thus reducing adhesive viscosity. This invention has a clever structure that effectively improves adhesive viscosity while cleaning dust from the object being coated during application, preventing adhesive from being applied to dust and thus reducing adhesive viscosity.

10. An automatic adhesive application method for glass, characterized in that, The automatic adhesive coating equipment for glass as described in claim 9, wherein the adhesive coating method includes the following steps: Step S1: Clamp the glass (19) on the clamp (18), adjust the pressure of the control component (31), start the first switch (16) of the support component (11), the clamp (18) clamps the glass (19) and moves it towards the lower part of the moving support rod (21), the moving belt (27) drives the moving block (26) and the slider (25) to move towards one side of the clamp (18), when the glue application component (40) reaches above the glass (19), the glue application component (40) moves downward to apply glue to the glass (19); Step S2: As the dispensing tube (43) moves toward the glass (19), the air pump (32) applies pressure to the glue container (42), squeezing the glue in the container (42) out of the dispensing tube (43). While the air pump (32) applies pressure to the glue container (42), it can also blow air into the preheating body (51). The airflow blown out by the air pump (32) enters the preheating body (51) to form a pushing airflow F1. When the pushing airflow F1 pushes against the friction plate (57), a portion of the airflow accumulates between the friction plate (57) and the air pump (32). The friction plate (57) moves downward, and the tension spring (561) stretches, so that the friction plate (57) can rub downward against the wall of the preheating body (51), thereby generating heat. The generated heat is used to heat the glue inside the glue bucket (42), and another part enters the next preheating structure (53) through the air outlet (570). The pushing airflow F1 of the next preheating structure (53) also causes the friction plate (57) of the next preheating structure (53) to rub against the wall of the preheating body (51), thereby generating heat. The generated heat is used to heat the glue inside the glue bucket (42). Step S3: After the glue is applied to the glass (19), the glue application assembly (40) moves upward, the control component (31) is turned off, the air pump component (32) stops applying pressure, the glue returns to the glue bucket (42), and at the same time the air pump component (32) stops blowing air to the preheating body (51). The pushing airflow F1 finally flows out from the air outlet (570) of the glue dispensing preheating structure (54), the tension spring (561) recovers, and the friction plate (57) rubs upward against the wall of the preheating body (51), so that the wall of the preheating body (51) generates heat. The generated heat is used to heat the glue inside the glue bucket (42). After moving to the next glue application position, the control component (31) of the air pump assembly (30) will start and continue to cycle until the glue application is completed. Step S4: After applying adhesive to the adhesive assembly (40) for a period of time, the wall temperature of the preheating body (51) rises, the temperature of the adhesive inside the glue bucket (42) rises, and the shape memory alloy (560) of the dispensing preheating structure (54) will be heated and contracted, causing the friction plate (57) to rub the preheating body (51) higher. At the same time, the pushing airflow F1 that finally flows out from the air outlet (570) of the dispensing preheating structure (54) can also blow away the dust adhering to the glass (19).
