Description

Technical Field

[0001] The present invention relates to the technical field of cabinet door production, and more particularly to a door stile gluing mechanism for an automatic assembly line of cabinet doors. Background Art

[0002] A cabinet door is a door installed on a cabinet, usually assembled from multiple boards. When assembling, the multiple boards are joined together and then assembled. Since the cabinet door is opened and closed relatively frequently, in order to ensure the strength of the cabinet door, nails are usually driven at the joints of the boards to ensure the joint strength.

[0003] During the production of cabinet doors, door stiles need to be provided on both sides of the door head and the core board. When assembling the door stiles, glue needs to be applied to the edges of the door stiles and then the door stiles are joined and assembled with the door head and the core board. Currently, the glue application of the door stiles is manually carried out. Since the types of glue applied at the joints of the door stiles with the door head and the core board are different, the glue application process is relatively cumbersome, and uneven glue application easily leads to poor bonding or even glue overflow of the cabinet door, affecting the overall effect and quality of the cabinet door.

[0004] Although there are also some two-component glue spraying devices on the market, their structures are relatively complex, and the glue cleaning is relatively cumbersome when the equipment stops. Summary of the Invention

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The door stile glue coating mechanism for the automatic assembly line of cabinet doors, in combination with Figures 1 to 4 As shown in the figure, it includes a door stile conveyor belt 304, which is arranged on both sides of the main conveyor belt 1 and is used to convey the door stile 302. The door stile conveyor belt is vertically arranged with the main conveyor belt. A door stile conveyor motor 303 is arranged at the side end of the door stile conveyor belt 304 to drive the door stile conveyor belt to rotate and convey the door stile forward. Above the front end of the door stile conveyor belt 304, there is a glue spraying cross beam 301, and a double glue spraying assembly 305 is arranged on the glue spraying cross beam through a chain synchronous belt module. A glue spraying translation motor 306 is arranged on the glue spraying cross beam to drive the double glue spraying assembly to move left and right along the glue spraying cross beam. A pre-assembly control cabinet is arranged beside the frame 5, and the door stile conveyor motor and the glue spraying translation motor are respectively electrically connected to the pre-assembly control cabinet.

[0018] An AB glue machine 900 and a silicone glue machine 800 are arranged on the frame 5. The AB glue machine is used to provide AB glue for the double glue spraying assembly, and the silicone glue machine 800 is used to provide silicone glue for the double glue spraying assembly. The AB glue machine 900 and the silicone glue machine 800 are respectively connected to the double glue spraying assembly through glue pipes.

[0019] The double glue spraying assembly 305 includes a slider that moves left and right along the glue spraying cross beam. A double glue head seat 317 is arranged on the slider. An AB glue supply unit that is connected to the AB glue machine 900 through a glue pipe and is used to apply AB glue to the door stile and a silicone glue supply unit that is connected to the silicone glue machine 800 through a glue pipe and is used to apply silicone glue to the door stile are arranged on the double glue head seat 317. A glue spraying lifting motor 307 is arranged on the slider to drive the double glue head seat to move up and down. The glue spraying lifting motor is electrically connected to the pre-assembly control cabinet.

[0020] The AB glue supply unit includes two single-component dispensing valves 318 arranged on the double glue head seat 317. The single-component dispensing valves 318 are respectively connected to the AB glue machine 900 through glue hoses. The bottoms of the two single-component dispensing valves 318 are connected to an AB glue hose 320 through a mixing tube inside the mixing tube seat 319 for mixing the AB glue. The bottom end of the AB glue hose 320 is provided with an AB glue head 308 for applying glue to the edge of the door stile. The single-component dispensing valve is electrically connected to the pre-assembly control cabinet.

[0021] The AB glue hose is a plastic mixing glue hose, and a steel sleeve is sleeved on the AB glue hose, which improves the pressure resistance level. On the basis of low-cost consumables, high-pressure mixing and spraying of glue are realized.

[0022] The AB glue head has a special-shaped structure, which is the same as the groove-shaped structure of the door stile. Multiple glue spraying holes are opened on the AB glue head, realizing precise glue application to the groove of the door stile.

[0023] The AB glue head 308 is arranged at the bottom end of the AB glue hose through the mounting bolt 323, and can replace a suitable AB glue head according to different door stiles, realizing glue application operations for different door stiles. At the same time, after replacing the AB glue head, the replaced AB glue head is cleaned to realize the rotation use of the AB glue head, reducing the downtime of the equipment.

[0024] The glue in the AB glue machine is transported to the two single-component dispensing valves through the glue hose. The glue in the two single-component dispensing valves enters the AB glue hose through the mixing tube in the mixing tube seat for mixing. The mixed glue enters the glue application position of the door stile through the AB glue head at the bottom end for glue application, realizing the automatic transportation of the two-component glue.

[0025] The silicone glue supply unit includes a silicone glue hose 322 arranged on the double glue head seat 317. The silicone glue hose is connected to the silicone glue machine 800 through a glue hose. The bottom of the silicone glue hose 322 is provided with a silicone glue head 309 for caulking the door stile. A double-rod cylinder 321 is arranged on the double glue head seat 317 above the silicone glue hose 322 for injecting the silicone glue in the silicone glue hose into the groove of the door stile through the silicone glue head. The double-rod cylinder is electrically connected to the pre-assembly control cabinet.

[0026] The silicone glue in the silicone glue machine is transported to the silicone glue hose through the glue hose. The double-rod cylinder above the silicone glue hose pushes the silicone glue in the silicone glue hose into the silicone glue head to apply glue to the door stile.

[0027] A push plate assembly is arranged below the end of the door stile conveyor belt 304 for transporting the glue-applied door stile to the door head and the core board for subsequent splicing.

[0028] The push plate assembly includes a pull rod 312 disposed in front of the end of the door stile conveyor belt 304. A pull rod suction cup 313 is provided on the upper end of the pull rod 312 facing the side of the door stile conveyor belt. The lower end of the pull rod 312 is hinged to the frame 5 below the door stile conveyor belt. A pull rod cylinder 311 is provided below the door stile conveyor belt. The end of the pull rod expansion link is hinged to the bottom end of the pull rod. The pull rod cylinder is electrically connected to the pre-assembled control cabinet.

[0029] When applying glue to the door stile in the present invention, the door stile is placed on the door stile conveyor belts on both sides of the main conveyor belt. After the door stile conveyor belt conveys the door stile to the front end, the suction cup on the pull rod sucks the door stile to fix the door stile for glue spraying operation. The glue spraying translation motor moves the AB glue heads on the double glue head seat above the edge of the door stile groove. The glue spraying lifting motor drives the AB glue heads into the groove of the door stile. The AB glue heads apply AB glue into the groove at the joint of the door stile and the door head. After the AB glue is applied, the single-component glue dispensing valve closes. During the process of the double glue head seat moving towards the middle of the door stile, the double rod cylinder works to push the glass glue in the glass glue tube into the groove at the joint of the door stile and the core board. When it moves to the joint of the other end door stile and the door head, the double rod cylinder stops working, and the single-component glue dispensing valve opens to apply AB glue into the groove. After the glue application is completed, the pull rod cylinder pulls the bottom end of the pull rod backward. Since the pull rod is hinged to the middle of the vehicle frame, the upper end of the pull rod drives the door head to flip, and the door stile changes from the vertical direction to the horizontal direction for subsequent splicing operation.
