Description

Technical Field

[0001] The invention relates to the technical field of sliding door assembly, and in particular to an upper rail sliding door assembly production line. Background Art

[0002] The upper track sliding door is a common door design. The sliding door is installed on the track system and is opened or closed by pushing and pulling the slide rail. The sliding door is mainly composed of a U-shaped door frame, rollers, glass panels and straight door frames. During production and assembly, the U-shaped door frame is usually inserted into the glass panel first, and then the rollers are inserted into the corresponding positions of the U-shaped door frame to slide with the slide rails. The straight door frame is then inserted into the glass panel and docked with the U-shaped door frame. Finally, the straight door frame is connected to the U-shaped door frame by screws to fix the glass panel in the closed space formed by the U-shaped door frame and the straight door frame.

[0003] The existing installation method of sliding doors requires manual insertion of the C-shaped door frame into the glass plate to complete the docking of the C-shaped plate, and then flipping the docked C-shaped door frame and the glass plate, and then docking and installing the straight door frame with the C-shaped door frame and the glass plate. The operation is cumbersome, and the efficiency of sliding door assembly needs to be improved. In addition, there is a risk of the glass plate slipping or breaking during the flipping process. In addition, the screw holes for installing screws on the straight door frame and the C-shaped door frame are easily deflected, resulting in the inability to accurately align the screws when installing them, which increases the difficulty of installation and affects the overall stability of the sliding door.

[0043] like Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the driving part 24 includes a slide plate 240, and two slide plates 240 are symmetrically arranged on the bottom plate 11. The two slide plates 240 slide up and down and penetrate the bottom plate 11. A push-pull rod 241 is fixedly installed between the two slide plates 240. The first vertical plate 30 and the second vertical plate 40 are both provided with a third waist groove. The opposite back surfaces of the first vertical plate 30 and the second vertical plate 40 are both slidably installed with an L-shaped plate 242. The first connecting rod 34, the second connecting rod 44 and the corresponding L The horizontal section of the molded plate 242 is fixedly connected, and the push-pull rod 241 movably passes through the two No. 3 waist grooves and the two L-shaped plates 242. A fixed block 243 is installed in the middle of the push-pull rod 241, and a telescopic cylinder 244 is installed on the lower end surface of the bottom plate 11.

[0045] During operation, after the glass plate, the U-shaped door frame and the linear door frame are placed in the corresponding positions, the telescopic cylinder 244 pulls the push-pull rod 241 downward through the fixed block 243, and the push-pull rod 241 pulls the two L-shaped plates 242 downward, and the two L-shaped plates 242 pull the corresponding No. 1 connecting rod 34 and No. 2 connecting rod 44 downward to fix the U-shaped door frame and the linear door frame. At the same time, the downward movement of the fixed block 243 pulls the No. 1 support plate 230 and the No. 2 support plate 230 through the driving rod 246. 2 moves toward the middle of the C-shaped plate 20, and the first support plate 230 and the second support plate 232 drive the corresponding first pushing plate 231 and the second pushing plate 233 to move synchronously toward the glass plate to squeeze and align the glass plate, and then the suction cup 21 adsorbs and fixes the aligned glass plate, and then the execution part 25 first drives the C-shaped door frame to insert into the glass plate. During the insertion of the C-shaped door frame into the glass plate, it cooperates with the unlocking member 5 to release the squeezing of the glass plate by the pushing part 23 to avoid interfering with the insertion of the C-shaped door frame into the glass plate.

[0046] like Figure 1 and Figure 7As shown, the unlocking member 5 includes a rectangular plate 50. The upper left sides of the second pushing plates 233 are provided with inclined surfaces that slope from top to bottom and leftward. A rectangular plate 50 is installed on one side of the first pushing plate 231 close to the U-shaped plate 20 and on one side of the second pushing plate 233 close to the U-shaped plate 20.

The guide post 51 slidably penetrates through the corresponding first support plate 230 and second support plate 232. Compression springs 52 are installed between the first support plate 230 and the corresponding rectangular plate 50, and between the second support plate 232 and the corresponding rectangular plate 50.

[0047] As Figure 2 , Figure 3 , Figure 7 and Figure 8 shown, the linkage member 6 includes a receiving plate 60. A receiving plate 60 is slidably installed up and down on the left and right sides of the two vertical sections of the U-shaped plate 20.

A limiting post 63 corresponding one-to-one to the receiving plate 60 is installed on one side of the connecting plate 62 close to the U-shaped plate 20. Limiting holes corresponding one-to-one to the limiting posts 63 are opened on the receiving plates 60.

[0048] As Figure 1 , Figure 2 and Figure 4 shown, the execution part 25 includes a lead screw 250. Lead screws 250 are rotatably installed on the left and right sides of the U-shaped plate 20 through bearing seats. The two lead screws 250 are respectively threadedly connected to the corresponding first vertical plate 30 and second vertical plate 40. Servo motors 251 corresponding one-to-one to the lead screws 250 are symmetrically installed at the lower left and right of the bottom plate 11. The servo motors 251 are connected to the corresponding lead screws 250 through belt drives.

[0049] During specific operation, the servo motor 251 on the left side drives the screw rod 250 on the left side to rotate through the corresponding belt, and the screw rod 250 on the left side rotates to drive the No. 1 vertical plate 30 to move toward the C-shaped plate 20, so that the fixed C-shaped door frame moves toward the glass plate to insert the C-shaped door frame plate into the glass plate. In the process of inserting the C-shaped door frame into the glass plate, the C-shaped door frame will conflict with the inclined surface of the No. 2 pushing plate 233, so that the No. 2 pushing plate 233 will be pushed downward as the C-shaped door frame moves, so that the No. 2 pushing plate 233 will be separated from the glass plate and the compression spring 52 will be compressed at the same time, and the No. 2 pushing plate 233 will move downward. When the glass plate is moved, the corresponding connecting plate 62 is pushed downward by the corresponding guide column 51, and the connecting plate 62 drives the corresponding receiving plate 60 to move downward through the limiting column 63, and the receiving plate 60 drives the No. 1 pushing plate 231 to move downward through the T-shaped column 61 and the corresponding guide column 51, so that the No. 1 pushing plate 231 is separated from the glass plate, and the upper ends of the No. 1 pushing plate 231 and the No. 2 pushing plate 233 will contact the lower end surface of the U-shaped door frame. During the above process, the glass plate is always fixed by the suction cup 21; after the U-shaped door frame is moved into place, the roller is manually placed at the corresponding position of the U-shaped door frame.

[0050] After the roller is placed, the servo motor 251 on the right side drives the screw rod 250 on the right side to rotate through the corresponding belt, and the screw rod 250 on the right side drives the second vertical plate 40 to move toward the C-shaped plate 20, so that the fixed linear door frame moves toward the glass plate to insert the linear door frame into the glass plate. At the same time, the linear door frame is docked with the C-shaped door frame, and then the linear door frame is fixedly connected with the C-shaped door frame by screws.

[0051] After the sliding door is assembled, the telescopic cylinder 244 pushes the push-pull rod 241 to move upward through the fixed block 243, and the push-pull rod 241 pushes the L-shaped plate 242 to move upward, and the L-shaped plate 242 drives the No. 1 pressure plate 33 and the No. 2 pressure plate 43 away from the corresponding U-shaped door frame and the straight door frame. At the same time, the fixed block 243 will push the No. 1 support plate 230 and the No. 2 support plate 232 to move through the driving rod 246, and the No. 1 support plate 230 and the No. 2 support plate 232 will push the corresponding No. 1 pushing plate 231 and the No. 2 pushing plate 233 to move to the side away from the glass plate, and then the two servo motors 251 drive the two screws 250 to rotate, so that the No. 1 docking mechanism 3 and the No. 2 docking mechanism 4 are away from the glass plate, and the suction and fixation of the glass plate by the suction cup 21 are released, and then the assembled sliding door is removed, and the above operation is repeated to continue the assembly and processing of the sliding door.
