Description

Technical Field

[0001] The invention relates to the field of bathrooms, and in particular to an intelligent automatic PUR hot melt adhesive gluing device for a shower room. Background Art

[0002] At present, gluing equipment is widely used in the bathroom industry. For example, the glass of shower rooms and balcony glass panoramic doors and windows generally needs to be bonded to pipes, such as aluminum / stainless steel. At this time, it is necessary to first use the gluing equipment to inject hot melt glue into the glue groove on the pipe, and then insert the connecting edge of the glass into the glue groove of the pipe. The hot melt glue in the glue groove is used to bond the glass and the pipe together, so that the glass and the pipe form a whole.

[0003] However, the working environment temperature has a great impact on the bonding between pipes and hot melt adhesive, and between pipes and glass, especially in winter or in a lower working environment temperature. The temperature of the metal pipe surface is lower, which will cause the bonding speed between the pipe and the hot melt adhesive to slow down, and the adhesion between the pipe and the hot melt adhesive to decrease, affecting the bonding quality between the pipe and the hot melt adhesive, and then affecting the connection quality between the pipe and the glass. If there is a problem with the connection between the pipe and the glass, there will be certain safety risks in the use of the finished product.

[0004] Therefore, it is necessary to improve the existing glue applying equipment. Summary of the invention

[0038] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0039] Embodiment 1: Figures 1 to 8 As shown, this embodiment provides an intelligent automatic PUR hot melt adhesive gluing device for a shower room, which at least includes:

[0040] A workbench 1, on the top surface of which a pipe preheating zone 2 is provided, in which a heating module 21 is provided, the pipe preheating zone 2 is used to preheat the pipe to be glued so that the surface temperature of the pipe to be glued reaches a preset gluing temperature, and the pipe to be glued is a metal pipe;

[0043] The gluing module 5 is arranged on the multi-axis moving mechanism 4. The multi-axis moving mechanism 4 is used to drive the gluing module 5 to move in multiple axes. The gluing module 5 is used to inject hot melt glue into the glue groove of the pipe to be glued;

[0044] A temperature detection module 6, arranged on the workbench 1, is used to detect the surface temperature of the pipe to be glued;

[0045] The control system 7 is electrically connected to the heating module 21, the multi-axis moving mechanism 4, the gluing module 5 and the temperature detection module 6 respectively. The control system 7 controls the operation of the heating module 21 according to the surface temperature of the pipe to be glued fed back by the temperature detection module 6, so that the surface temperature of the pipe to be glued is stably maintained at a preset gluing temperature.

[0046] The present embodiment provides an intelligent automatic PUR hot melt adhesive gluing device for a shower room, which can improve the adhesion between the pipe and the hot melt adhesive.

[0047] Specifically, the pipe to be glued is preheated by setting the pipe preheating zone 2 so that the surface temperature of the pipe to be glued reaches the preset gluing temperature. When the surface temperature of the pipe to be glued reaches the preset gluing temperature, the adhesion between the pipe and the hot melt adhesive will increase significantly, especially in winter or at a relatively low working environment temperature. This can ensure the bonding quality between the pipe and the hot melt adhesive, thereby ensuring the connection quality between the pipe and the glass, and reducing the quality and safety risks of the finished product.

[0048] Furthermore, a distance measuring module 8 is provided on the workbench 1, and the distance measuring module 8 is electrically connected to the control system 7. The distance measuring module 8 is used to detect the length of the pipe to be glued and the length, width and depth of the glue groove of the pipe to be glued. The control system 7 calculates the required total amount of hot melt adhesive according to the length, width and depth of the glue groove, and obtains the glue output of the glue module 5 per unit time according to the moving speed of the glue module 5, so that the glue output of the glue module 5 matches the moving speed of the glue module 5, and the hot melt adhesive is evenly injected into the glue groove. The design is simple and reasonable, which can improve the glue quality of the glue module 5 to a certain extent, thereby ensuring the uniformity of the adhesion between the pipe and the hot melt adhesive. Of course, the distance measuring module 8 may include a plurality of laser sensors arranged at different positions, which are respectively used to measure the required data to be measured.

[0049] Furthermore, a first image detection and recognition module 9 is provided on the multi-axis moving mechanism, and the first image detection and recognition module 9 is electrically connected to the control system 7. The first image detection and recognition module 9 is used to take pictures of the pipe to be glued, and the control system 7 generates a preset gluing trajectory of the gluing module 5 according to the trajectory of the glue groove in the photo fed back by the first image detection and recognition module 9, and the control system 7 drives the gluing module 5 to operate according to the preset gluing trajectory through the multi-axis moving mechanism 4. The design is simple and reasonable, thereby realizing the automatic gluing of the gluing equipment, improving the gluing quality of the gluing equipment, and reducing the occurrence of hot melt adhesive overflow caused by gluing deviation.

[0050] The control system 7 can identify the type of the pipe to be glued based on the photos fed back by the first image detection and recognition module 9, and the control system 7 controls the heating module 21 to work according to the type of pipe, so that the surface temperature of the pipe to be glued is stably maintained at the preset gluing temperature, wherein the pipe types include aluminum pipes and stainless steel pipes, the preset gluing temperature of aluminum pipes is 55°-65°, and the preset gluing temperature of stainless steel pipes is 65°-75°. It has a simple structure and can automatically adjust the preheating temperature of the pipe preheating zone 2 according to different pipe types, so that the surface temperature of the pipe reaches the optimal adhesion temperature with the hot melt adhesive, thereby ensuring the bonding quality between the pipe and the hot melt adhesive, and then ensuring the connection quality between the pipe and the glass, reducing the quality and safety risks of the finished product.

[0051] Preferably, the preheating temperature of the aluminum profile is set to 60°C, and the temperature of the stainless steel constant temperature zone is set to 70°C.

[0052] In the present embodiment, a second image detection and recognition module 10 is provided on the gluing module 5. In the process of injecting hot melt adhesive into the glue groove, the second image detection and recognition module 10 can continuously take pictures of the glue groove. The control system 7 obtains the center of the glue groove according to the pictures fed back by the second image detection and recognition module 10, and dynamically adjusts the preset gluing trajectory in real time accordingly. The control system 7 controls the operation of the multi-axis moving mechanism according to the adjusted preset gluing trajectory, so as to dynamically adjust the glue outlet point of the gluing module 5 in real time, so that the glue outlet point of the gluing module 5 is always located in the center of the glue groove. The design is reasonable, which can further improve the gluing quality of the gluing equipment, so that the hot melt adhesive ejected by the gluing module 5 is always in the center of the glue groove, and the hot melt adhesive evenly fills the glue groove in the center of the glue groove, thereby ensuring the uniformity of adhesion between the pipe and the hot melt adhesive.

[0053] Further, such as Figure 5As shown, it also includes a PUR hot melt adhesive machine and a high-temperature adhesive delivery pipe. The PUR hot melt adhesive machine is used to heat the solid PUR hot melt adhesive into liquid PUR hot melt adhesive, and input it to the gluing module 5 through the high-temperature adhesive delivery pipe. After the PUR hot melt adhesive is heated and melted by the PUR hot melt adhesive machine, it is transported to the gluing module 5 through the high-temperature adhesive delivery pipe [screw type rotary extrusion) + pressure feedback device] to discharge the adhesive. The flow error of the PUR hot melt adhesive is ≤3%, thereby improving the accuracy of the gluing equipment, effectively reducing the waste of PUR hot melt adhesive, and reducing the occurrence of solidification blockage caused by the residual PUR hot melt adhesive inside the machine.

[0054] Furthermore, Figure 6 As shown, the gluing module 5 at least includes a mounting seat 51, a driving motor 52, a glue pump 53, a glue pipe 54 and a mounting bracket 55, wherein the mounting seat 51 includes a base 511, a top plate 512 and a side plate 513 connected to the base 511 and the top plate 512 on both sides, the driving motor 52 is arranged on the top of the top plate 512, the glue pump 53 is arranged on the base 511, the driving shaft 521 of the driving motor 52 is connected to the glue pump 53, the glue pipe 54 is arranged on one side of the base 511, the input end of the glue pump 53 is connected to the output end of the high-temperature glue delivery pipe, the output end of the glue pump 53 is connected to the glue pipe 54, the mounting bracket 55 is arranged on one side of the top plate 512, and the second image detection and recognition module 10 is arranged on the mounting bracket 55, which has a simple structure, and the overall structure of the gluing module 5 is simple and reasonable, and can improve the working stability and reliability of the gluing module 5.

[0055] Furthermore, Figure 7As shown, the glue pump 53 includes a housing 530, a first gear 531 and a second gear 532, wherein a cavity 5301 is provided in the housing 530, a glue inlet channel 5302 and a glue outlet channel 5303 are provided on both sides of the cavity 5301, a rotating shaft 533 is provided in the cavity 5301, the first gear 531 and the second gear 532 are both provided in the cavity 5301, and the first gear 531 is connected to the rotating shaft 533, and the driving shaft 521 of the driving motor 52 extends into the cavity 530 1 is connected with the second gear 532, the first gear 531 and the second gear 532 are meshed, the driving motor 52 can drive the second gear 532 to drive the first gear 531 to rotate, and the first gear 531 and the second gear 532 are rotated to output the hot melt adhesive in the cavity 5301 to the glue tube 54 or to make the hot melt adhesive in the glue tube 54 flow back into the cavity 5301. The structure is simple, and the glue pump 53 provided in this embodiment can improve the accuracy of the glue injection of the glue injection module 5, especially the accuracy of the glue injection amount. Specifically, when the second gear 532 rotates forward, the first gear 531 is driven to rotate by the second gear 532, and the first gear 531 and the second gear 532 rotate together to output the hot melt adhesive in the cavity 5301 to the glue tube 54; when the second gear 532 rotates reversely, the first gear 531 is driven to rotate by the second gear 532, and the first gear 531 and the second gear 532 rotate together to make the hot melt adhesive in the glue tube 54 flow back into the cavity 5301. In particular, when the glue module 5 is about to temporarily stop working, the hot melt adhesive in the glue tube 54 flows back into the cavity 5301 to avoid glue leakage and overflow, thereby reducing the waste of hot melt adhesive and ensuring the cleanliness of the workbench.

[0056] Furthermore, a heating and glue melting component 56 is provided outside the glue tube 54, and the heating and glue melting component 56 is electrically connected to the control system 7. The control system 7 controls the heating and glue melting component 56 to heat the glue tube 54, so that the temperature of the glue tube 54 reaches the preset glue outlet temperature, thereby improving the adhesion between the hot melt adhesive and the pipe. In addition, since the glue tube 54 is long, the flow path of the hot melt adhesive in the glue tube 54 is long. Therefore, in a working environment with a low temperature, such as winter, the hot melt adhesive is easy to solidify in the glue tube and cause the glue tube 54 to be blocked. The aforementioned problem can be solved by adding a heating and glue melting component 56. The heating and glue melting component 56 heats the glue tube 54, so that the temperature of the glue tube 54 reaches the preset glue outlet temperature, and the hot melt adhesive is kept in a liquid state as much as possible, thereby avoiding the situation where the liquid hot melt adhesive solidifies in the glue tube 54 and causes blockage.

[0057] In this embodiment, the first image detection and recognition module 9 can take pictures of the pipe after gluing, and the control system 7 determines the gluing quality of the gluing module 5 according to the pictures fed back by the first image detection and recognition module 9. The structure is simple, thereby realizing the function of quality inspection and preventing defective products from entering the market.

[0058] A glue guiding groove is provided in the glue tube 54, and the glue guiding groove is spiral-shaped, so that the hot melt glue forms a vortex flow when being extruded, thereby reducing the wall hanging phenomenon.

[0059] Furthermore, a support assembly 11 is provided on the multi-axis moving mechanism 4, and the support assembly 11 at least includes an X-axis support 111, a Y-axis support 112 and a Z-axis support 113.

The first image detection and recognition module 9 is provided on the Z-axis support 113. By adjusting the support assembly 11 to align the first image detection and recognition module 9 with the center of the pipe to be glued, the design is reasonable, thereby further improving the gluing quality of the gluing equipment, so that the hot melt adhesive sprayed by the gluing module 5 is always sprayed in the center of the glue groove, and the hot melt adhesive evenly fills the glue groove in the center of the glue groove, thereby ensuring the uniformity of adhesion between the pipe and the hot melt adhesive.

[0060] Preferably, the pipe preheating zone 2 includes an aluminum pipe preheating zone and a stainless steel pipe preheating zone. The heating module 21 of the aluminum pipe preheating zone adopts a PTC heating sheet, and the heating module 21 of the stainless steel pipe preheating zone adopts an infrared heating tube. The temperature range that the PTC heating sheet and the infrared heating tube can heat is 0-120°, so that the surface temperature of the pipe reaches the optimal adhesion temperature between the pipe and the hot melt adhesive, thereby ensuring the bonding quality between the pipe and the hot melt adhesive, and then ensuring the connection quality between the pipe and the glass, reducing the quality and safety risks of the finished product. In addition, the temperature range that the PTC heating sheet and the infrared heating tube can heat is relatively large, so that more different environments and different types of pipe preheating requirements can be used.

Furthermore, two gluing modules 5 are provided side by side and spaced apart on the Z-axis moving mechanism 43.

[0062] In this embodiment, a temperature-adjustable sealing device 13 is provided on the workbench 1, and the temperature-adjustable sealing device 13 at least includes a shell 131 and a heating component 132, wherein a cavity 1310 is formed in the shell 131, and the heating component 132 is annularly arranged on the shell 131 and is electrically connected to the control system 7, a support member 133 is horizontally placed on the shell 131, and sealing oil is filled in the cavity 1310, and the glue-applying module 5 can be moved to the top of the temperature-adjustable sealing device 13. The gluing tube 54 of the gluing module 5 can be extended into the sealing oil in the cavity 1310 and rest against the support member 133. The control system 7 can control the heating component 132 to heat the sealing oil, and the sealing oil prevents the hot melt adhesive in the gluing tube 54 from solidifying due to contact with the air. The structure is simple and the design is reasonable, so that the hot melt adhesive in the gluing tube 54 can be prevented from solidifying due to contact with the air when the machine is paused or shut down, causing the gluing tube 54 to be blocked, which is beneficial to improving the stability and reliability of the gluing equipment.
