Description

Technical Field

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

[0002] A cabinet door is a door installed on a cabinet, usually assembled from multiple boards. During assembly, after applying adhesive to the splicing surfaces of the boards, multiple boards are spliced together for assembly. Since the cabinet door is frequently opened and closed, in order to ensure the strength of the cabinet door, nails are usually driven at the splicing joints of the boards to ensure the splicing strength. However, the assembly of existing cabinet doors mostly relies on manual splicing, which has a relatively high labor intensity, low assembly efficiency, and manual assembly cannot guarantee the splicing force, making it difficult to ensure the assembly effect of the cabinet door.

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] An automatic assembly line for cabinet doors, in combination with Figure 1 As shown, it includes a main conveyor belt 1. On the side of the main conveyor belt 1, there are successively arranged a door head conveying mechanism 100, a core board conveying mechanism 200, a door stile conveying mechanism 300, a shunt machine 400, a nailing mechanism 500, a confluence machine 600, and a belt conveyor 700. On the side of the main conveyor belt 1, there are arranged an operation cabinet 2, a pneumatic control cabinet 3, and a nailing machine operation cabinet 4. The door head conveying mechanism, the core board conveying mechanism, and the door stile gluing mechanism are respectively electrically connected to the operation cabinet. The nailing mechanism is electrically connected to the nailing machine operation cabinet. The pneumatic control cabinet is connected to an air storage tank and is connected to each mechanism through an air pipe.

[0021] The door head conveying mechanism 100 is staggered into two groups and is respectively arranged on both sides of the main conveyor belt 1 to convey two door heads respectively. The structural schematic diagram of the door head conveying mechanism is as Figure 2 and Figure 3 As shown, it includes a door head support 101. On the door head support 101, there are arranged two door head fixing brackets 103. The door head 6 is placed between the two door head fixing brackets 103. On the door head support 101 below the door head 6, there is arranged a door head pushing mechanism for pushing the door head at the bottom between the door head fixing brackets. Behind the door head pushing mechanism, there is a conveyor belt for conveying the pushed-out door head. Above the end of the conveyor belt, there is arranged a door head translation slide rail 109. On the door head translation slide rail 109, there is arranged a door head translation mechanism. At the side end of the door head translation slide rail 109, there is arranged a door head translation motor for driving the door head translation slider to move. The door head pushing mechanism, the door head translation mechanism, and the door head translation motor are respectively electrically connected to the operation cabinet.

[0022] On the door head support 101, there are arranged two door head fixing plates 102 through sliders. The two door head fixing brackets 103 are respectively arranged on the two door head fixing plates 102. A bidirectional lead screw is transversely arranged on the door head support 101. The two door head fixing plates 102 are respectively sleeved at both ends of the bidirectional lead screw. At the end of the bidirectional lead screw, there is arranged a door head second adjustment handle 108 for adjusting the distance between the two door head fixing brackets 103 to adapt to the conveying of door heads of different lengths.

[0023] The door head pushing mechanism includes a door head push plate bracket 104 arranged on the door head bracket 101, a door head push plate 106 is arranged on the door head push plate bracket 104, and a door head push plate cylinder 105 is arranged on the door head push plate bracket 104, which is used to drive the door head push plate to move. The door head push plate cylinder is connected to the air pressure control cabinet through an air pipe, and the door head push plate cylinder pushes the door head push plate bracket to move forward, driving the door head push plate to push the bottom door head forward. When the door head push plate moves to the end of the door head, the door head is transported forward through the conveyor belt at the rear. After the door head push plate retracts and can no longer support the door head, the door head moves down and waits for the next push.

[0024] The door head translation mechanism includes a door head translation slider 110 that is slidably set on the door head translation rail 109, and a door head suction cup cylinder 112 is set on the door head translation slider 110. The end of the telescopic rod of the door head suction cup cylinder is provided with a door head suction cup 111 through a suction cup connecting rod 113. The door head suction cup cylinder is connected to the air pressure control cabinet through an air pipe, and the door head translation slider is connected to the door head translation motor through a belt. The door head translation motor drives the door head translation slider to move along the door head translation rail through the belt. When the door head moves to the end of the conveyor belt, the door head suction cup cylinder pushes the suction cup to move downward and close to the door head. After the suction cup sucks the door head, the door head translation motor drives the door head translation slider to move on the door head translation rail. When it moves to the top of the main conveyor belt, the suction cup releases the door head and places the door head on the main conveyor belt for transmission.

[0025] The door head bracket 101 is set on the slide rail on the frame 5 through a slider. The frame 5 is provided with a screw rod that passes through the door head bracket 101. The end of the screw rod is provided with a first door head adjustment handle 107 for adjusting the position of the door head bracket to adapt to door heads of different widths.

[0026] When conveying the door head, first pass the position of the door head bracket and the door head fixed bracket according to the size of the door head, then place the door head between the two door head fixed brackets for stacking, and then start the door head push plate cylinder to push the push plate forward to push the door head at the bottom end between the door head fixed brackets forward, and push it to the conveyor belt for transmission. When it is transmitted to the tail end, the door head suction cup cylinder pushes the suction cup to move downward. After the suction cup sucks the door head, the door head translation slider drives the door head to move to the main conveyor belt. When it moves to the top of the main conveyor belt, the suction cup releases the door head and places the door head on the main conveyor belt for downward transmission. When the door head is conveyed, the door head push plate cylinder drives the push plate to retract. When the push plate is separated from the door head, the door head moves downward. The door head push plate cylinder pushes the push plate to continue to push the door head at the bottom forward for the next transmission. The door head conveying mechanisms staggered on both sides of the main conveyor belt place the door heads on the main conveyor belt respectively. There is a certain distance between the two door heads, which is used to place the core boards conveyed by the core board conveying mechanism.

[0027] The structure of the core plate conveying mechanism 200 is as follows: Figure 4 andFigure 6 As shown, it includes two core plate fixing brackets 201 arranged on the side frames of the main conveyor belt 1 for placing the core plates 7. Above the main conveyor belt 1, there is a gantry 202. Inside the gantry 202, a core plate translation plate 204 is slidably arranged. On the core plate translation plate 204, there is a core plate grabbing mechanism for grabbing the core plates at the top of the core plate fixing brackets 201. The core plate grabbing mechanism and the core plate translation motor are electrically connected to the operation cabinet.

[0028] The core plate grabbing mechanism includes a core plate suction cup bracket 207 arranged on the chip translation plate 204. On the core plate suction cup bracket 207, a core plate lifting plate 208 is arranged through a rack. Below the core plate lifting plate 208, there is a core plate suction cup 209. On the core plate suction cup bracket, there is a servo motor for driving the core plate lifting plate to move up and down through the rack. The core plate suction cup is connected to the air source.

[0029] The suction cup is a corrugated suction cup. A positioning block 212 is arranged between the two suction cups. On the core plate lifting plate 208, there is an elastic pressure rod 213. Through the cooperation of the corrugated suction cup with the positioning block between the suction cups and the elastic pressure rod, one end has a small suction force and the other end has a later suction force, so that the two core plates are gradually separated, realizing the separation and suction of the core plates with micro-air permeability and avoiding sucking two or more core plates.

[0030] When picking up the core plate, the servo motor on the core plate suction cup bracket pushes the core plate lifting plate to move downward. When the core plate suction cup touches the surface of the core plate, after the core plate suction cup sucks the core plate, the servo motor drives the suction cup lifting plate to move upward. When it moves above the core plate fixing plate, it moves above the main conveyor belt through the suction cup translation plate.

[0031] In the middle of the core plate lifting plate 208, there is an optical sensor 214 and an elastic pressure rod 213. Through the cooperation of the optical sensor and the elastic pressure rod, the detection of plate dropping is carried out to prevent the plate from falling due to insufficient suction and disrupting the production rhythm.

[0032] Inside the gantry 202, there is a rack 203 extending to the main conveyor belt 1. On the core plate translation plate 204, there is a core plate translation motor 205. On the core plate translation motor, there is a gear meshing with the rack 203. On the frame below the core plate fixing bracket 201, there is a slide rail parallel to the main conveyor belt 1. The core plate fixing bracket 201 is slidably arranged on the slide rail. When the core plate translation motor drives the gear to rotate, the gear meshes with the rack, realizing the movement of the core plate translation plate on the gantry along the slide rail, thereby realizing the transportation of the core plate.

[0033] Inside the gantry 202, there is a core plate translation slide rail 206 parallel to the rack. The core plate translation plate 204 is slidably arranged on the core plate translation slide rail 206. The core plate translation motor drives the core plate translation plate to move along the core plate translation slide rail.

[0034] The core board fixing frame 201 is arranged on the slide rail through the outer core board fixing frame ear plates 210. A number of ear plate mounting holes are provided on the slide rail, and an ear plate mounting hole 211 is provided on the core board fixing frame ear plate 210, which is used to adjust the position of the core board fixing frame to adapt to the fixing of core boards of different lengths.

[0035] After the core board is in place, by defining an appropriate release height, servo motor position control, and whether the photoelectric sensor can still detect the signal of the core board after releasing the core board, it can be judged whether two or more boards are adsorbed, further ensuring to avoid the possibility of accidentally adsorbing two or more boards and ensuring the stable operation of the equipment.

[0036] When conveying the core board to the main conveyor belt, first adjust the position of the core board fixing frame according to the size of the core board, then stack the core boards between the core board fixing frames. The servo motor drives the rack to drive the core board lifting plate to drive the suction cup to move downward. After sucking the core board by the suction cup, the servo motor drives the core board to move upward. When moving above the core board fixing frame, the core board translation motor drives the core board translation plate to move along the slide rail on the gantry towards the main conveyor belt direction. When moving above the main conveyor belt, the servo motor drives the core board to move downward. When the core board moves onto the main conveyor belt, the suction cup releases the core board and then picks up and conveys the next core board.

[0037] This application can also feed materials alternately at the left and right stations. During the process of feeding the core board, the equipment does not need to stop. After the core board feeding is completed, it is confirmed through the control button. After the core board at the left station is used up, the suction cup automatically goes to the right station for feeding, and at this time, the core board at the left station can be fed.

[0038] After the core board is placed, the door stile gluing mechanism 300 glues the two side door stiles. The structure of the door stile gluing mechanism is as Figures 7 to 10 shown. The door stile gluing mechanism 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 perpendicular to the main conveyor belt. A door stile conveying motor 303 is arranged at the side end of the door stile conveyor belt 304 and is used 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. A double glue spraying component 305 is arranged on the glue spraying cross beam through a chain. The double glue spraying component 305 is arranged on the chain through a sprocket. A glue spraying translation motor 306 is arranged on the glue spraying cross beam and is used to drive the double glue spraying component to move left and right along the glue spraying cross beam. A pre-assembly control cabinet is arranged beside the frame 5. The door stile conveying motor and the glue spraying translation motor are respectively electrically connected to the pre-assembly control cabinet, and the pre-assembly control cabinet is electrically connected to the operation cabinet.

[0039] On the frame 5, there are an AB glue machine 900 and a silicone glue machine 800. 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 hoses.

[0040] The double glue spraying assembly 305 includes a slider that moves left and right along the glue spraying cross beam. On the slider, there is a double glue head seat 317. On the double glue head seat 317, there is an AB glue supply unit that is connected to the AB glue machine 900 through a glue hose 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 hose and is used to apply silicone glue to the door stile. On the slider, there is a glue spraying lifting motor 307, which is used 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.

[0041] 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 with an AB glue hose 320 through a mixing tube in the mixing tube seat 319, which is used to mix the AB glue. The bottom end of the AB glue hose 320 is provided with an AB glue head 308, which is used to apply glue to the edge of the door stile. The single-component dispensing valve is electrically connected to the pre-assembly control cabinet.

[0042] 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 mixed glue spraying is realized.

[0043] The AB glue head has a special-shaped structure, which is the same as the groove-shaped structure of the door stile. There are multiple glue spraying small holes opened on the AB glue head, which realizes precise glue application to the groove of the door stile.

[0044] The AB glue head 308 is arranged at the bottom end of the AB glue hose through a 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.

[0045] The glue material in the AB glue machine is transported to the two single-component dispensing valves through the glue hose. The glue materials in the two single-component dispensing valves enter the AB glue hose through the mixing tube in the mixing tube seat for mixing.

On the double glue head seat 317 above the silicone sealant tube 322, there is a double-rod cylinder 321 for injecting the silicone sealant in the silicone sealant tube into the groove of the door stile through the silicone sealant head. The double-rod cylinder is electrically connected to the pre-assembly control cabinet.

[0047] The silicone sealant in the silicone sealant machine is transported into the silicone sealant tube through a hose. The double-rod cylinder above the silicone sealant tube pushes the silicone sealant in the silicone sealant tube into the silicone sealant head to apply sealant to the door stile.

[0048] The push plate assembly includes a pull rod 312 disposed in front of the end of the door stile conveyor belt 304. At the upper end of the pull rod 312, a pull rod suction cup 313 is provided on the side facing 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. Below the door stile conveyor belt, there is a pull rod cylinder 311. 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-assembly control cabinet.

[0049] A positioning assembly is provided at the front end of the push plate assembly. The structure of the positioning assembly is as Figures 11 to 13 shown, including lifting support plates 324 provided on the frames 5 on both sides of the main conveyor belt 1. On the frame 5 below the lifting support plates 324, there is a support lifting cylinder 326 for driving the lifting support plates 324 to move up and down to support the cabinet door for assembly operations.

[0050] On the left and right sides of the lifting support plates 324, there are support blocks 325. On the outside of the support blocks 325, there is a push plate 315. The push plate 315 has a stepped structure with a lower inner side and a higher outer side. On the lifting support plates 324 outside the push plate 315, there is a push plate cylinder 314 for pushing the push plate to push the door stile on the push plate towards the door head and the core board for assembly.

[0051] On the frame above the support blocks 325, there is a pressing block 328. On the frame, there is a pressing block lifting cylinder 327. The end of the pressure lifting cylinder expansion link is connected to the top end face of the pressing block for pushing the pressing block to press the core board and the door head to prevent the core board and the door head from shifting during the assembly process.

[0052] On the lifting support plates 324 between the two support blocks 325, there is a support plate 316 for supporting the middle part of the door stile to prevent the middle of the door stile from sagging during the assembly process. On the lifting support plates 324, there is a support plate cylinder 310 for pushing the support plate forward. During the assembly of the door stile, it can move forward with the door stile to ensure the support effect.

[0053] The support block 325 is a T-shaped support block with a wider inner width and a narrower outer width. The inner ends support the door head and the core board respectively, and the outer ends support the door stile, so that the door head, the core board and the door stile are on the same horizontal plane, ensuring the assembly effect.

[0054] When applying glue to the door stile, place the door stile on the door stile conveyors on both sides of the main conveyor belt. After the door stile conveyor moves the front end of the door stile conveyor, the suction cup on the pull rod sucks the door stile and fixes the door stile for convenient glue spraying operation. The glue spraying translation motor moves the AB glue heads on the double glue head seat above the edge of the groove of the door stile. The glue spraying lifting motor drives the AB glue heads to move 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 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 to apply glass glue into the groove at the joint of the door stile and the core board. When moving to the joint of the other end of the door stile and the door head, the double-rod cylinder stops working, and the single-component 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 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 operations.

[0055] During splicing, the lifting support cylinder at the bottom supports the door head, the core board on the main conveyor belt and the glued door stile, so that the door head, the core board and the door stile are on the same horizontal plane. At the same time, the pressing block lifting cylinder descends and presses between the door head and the core board. After fixing the door head and the core board, the push plate cylinder pushes the push plate forward to push the door stile, so that the groove of the door stile is assembled with the edges of the door head and the core board, improving the firmness of the assembly.

[0056] The glued and spliced cabinet door is conveyed backward by the main conveyor belt 1 for nailing. Since the operation process of the nailing mechanism is relatively slow, the assembled cabinet door is shunted by the shunting machine 400 to improve the production efficiency of the cabinet door.

[0057] The structure of the shunting machine 400 is as Figures 14 to 15As shown in the figure, it includes a main shunt conveyor roller 8 and a shunt conveyor roller 401.

The shunt conveyor roller 401 is arranged parallel to the main shunt conveyor roller 8. A shunt conveyor belt 402 is arranged between the main shunt conveyor roller 8 and the shunt conveyor roller 401, which is used to transport the cabinet door on the main shunt conveyor roller 8 to the shunt conveyor roller 401. A main conveyor motor 404 is arranged on the frame 5 below the main shunt conveyor roller 8, and a shunt conveyor motor is arranged on the frame 5 below the shunt conveyor roller 401, realizing the shunt transportation of the cabinet door. A shunt control box 414 is arranged beside the frame 5, which is used to control the shunt of the cabinet door.

The shunt conveyor support 410 is arranged on the shunt conveyor belt lifting bracket 403. The shunt conveyor lifting cylinder is electrically connected to the shunt control box. When the main shunt conveyor roller conveys the cabinet door to the nailing mechanism behind, the shunt conveyor belt descends to below the main shunt conveyor roller, and it will not affect the forward transportation of the cabinet door by the main shunt conveyor roller. When it is necessary to transfer the cabinet door to the shunt conveyor roller, the shunt conveyor belt rises, drives the cabinet door to break away from the main shunt conveyor roller, and then transports the cabinet door to above the shunt conveyor roller through the shunt conveyor belt. After that, the shunt conveyor belt descends, so that the cabinet door is placed on the shunt conveyor roller, and the cabinet door is sent to another nailing mechanism through the shunt conveyor roller.

[0060] On the outer sides of the main shunt conveyor roller 8 and the shunt conveyor roller 401, shunt fixed limit plates 406 are respectively arranged through shunt limit plate brackets 405.

[0063] When the assembled cabinet door is conveyed onto the shunt main conveyor roller, it is first conveyed to the nail - driving mechanism at the rear by the shunt main conveyor roller for nail - driving operation. The rear cabinet door needs to be conveyed onto the shunt conveyor roller. When conveying to the shunt conveyor roller, the shunt movable limiting plate rises, and at the same time the shunt conveyor belt rises. The rising height of the shunt movable limiting plate should be greater than the height of the cabinet door on the shunt conveyor belt, so that the shunt conveyor belt can drive the cabinet door to be conveyed to the shunt conveyor roller. When it reaches the shunt fixed limiting plate on the shunt conveyor roller, the shunt conveyor belt descends, placing the cabinet door on the shunt conveyor roller and conveying it to the nail - driving mechanism at the rear through the shunt conveyor roller, realizing the shunt operation of the cabinet door.
