Description

Technical Field

[0001] This utility model relates to the field of cabinet door manufacturing technology, and more specifically to a pre-assembly mechanism for an automatic cabinet door assembly line. Background Technology

[0002] Cabinet doors are doors installed on cabinets. They are usually assembled from multiple panels. During assembly, the panels are joined together. Because cabinet doors are opened and closed frequently, nails are usually driven into the joints of the panels to ensure the strength of the joints.

[0003] During the production of cabinet doors, door stiles are installed on both sides of the door header and the core panel. When assembling the stiles, adhesive needs to be applied to their edges before they are joined to the door header and core panel. Currently, the adhesive is applied manually to the stiles. Because different types of adhesive are used at the joints between the stiles and the door header / core panel, the process is tedious. Uneven adhesive application can easily lead to poor adhesion or even adhesive overflow during subsequent assembly, affecting the overall appearance and quality of the cabinet doors. Although there are some two-component adhesive spraying machines on the market, their structures are relatively complex, and cleaning up adhesive when the machine is stopped is cumbersome.

[0040] When applying adhesive to the door stile, place the stile on the door stile conveyor belts on both sides of the main conveyor belt. After the front end of the door stile conveyor belt is pulled back, the suction cups on the pull rod hold the stile in place for easy adhesive application. The adhesive application translation motor moves the AB adhesive head on the dual adhesive head holder above the edge of the door stile's groove. The adhesive application lifting motor drives the AB adhesive head to move into the groove of the door stile. The AB adhesive head applies AB adhesive into the groove where the door stile meets the door frame. After the AB adhesive is applied, the single-liquid dispensing valve closes, and the dual adhesive head holder... As the door stile moves towards the center, the double-rod cylinder pushes the silicone sealant tube to apply it into the groove where the stile meets the core panel. When it moves to the other end where the stile meets the door head, the double-rod cylinder stops working, the single-liquid dispensing valve opens, and AB glue is applied into the groove. After the glue is applied, the pull rod cylinder pulls the bottom of the pull rod backward. Since the pull rod is hinged to the middle of the frame, the upper end of the pull rod causes the door head to flip, and the stile changes from a vertical to a horizontal position to facilitate subsequent splicing operations.

[0041] During assembly, the bottom lifting support cylinder supports the door head, core board, and glued door stile on the main conveyor belt, ensuring that the door head, core board, and door stile are on the same horizontal plane. At the same time, the pressure block lifting cylinder descends and presses between the door head and core board to fix them in place. Then, the push plate cylinder pushes the push plate forward to push the door stile, allowing the groove of the door stile to assemble with the edge of the door head and core board, thus improving the stability of the assembly.
