Description

Technical Field

[0001] The utility model relates to the technical field of door panel processing, in particular to a door panel flipping structure. Background Art

[0002] In furniture manufacturing and industrial production, as a common component, the appearance quality of the door panel directly affects the quality of the final product and the market competitiveness. The traditional door panel painting process usually adopts a fixed painting table, and this structure has many limitations: the fixed painting table cannot be quickly flipped, resulting in a long painting process time and affecting production efficiency; since the door panel is fixed in position during the painting process, it is difficult to achieve multi-angle and all-round painting, and uneven painting is likely to occur; operators need to continuously adjust the position of the door panel during the painting process, increasing the complexity and safety risks of the operation; the fixed painting table is usually large in size, occupies more workshop space, and is not conducive to the optimization of the production process and the effective utilization of space.

[0003] To solve the above problems, some improved painting equipment has emerged in the industry, such as adjustable-angle painting tables, automated painting robots, etc. However, these devices still have problems such as complex operation, high cost, and poor adaptability. Therefore, improvements are needed. Summary of the Invention

[0004] The utility model aims at the defects of complex operation, high cost, and poor adaptability in the prior art, and provides a door panel flipping structure.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A door panel flipping structure includes a lifting device, a door panel bracket, a flipping device, and a transportation device. The transportation device includes an extended transportation rail, a transportation transmission device, and a column. The number of the transportation rails is two, the transportation rails are connected to the column, and the top surfaces of the two transportation rails form a transportation surface. The transportation transmission device drives the door panel bracket to move by means of the transportation rail. The door panel bracket includes an outer frame and an inner bracket. The inner bracket is connected to both ends of the door panel in the length direction. Both sides of the outer frame are placed on the transportation rail. The flipping device is arranged on the lifting device and cooperates with the lifting device to form a transportation position and a flipping position. In the transportation position, the flipping device is lower than the transportation surface. In the flipping position, the door panel is separated from the transportation surface by means of the cooperation between the inner bracket and the lifting device.

[0007] The transportation device is a transportation equipment in a production line that can extend to both sides, which makes the applicability of this structure higher. And taking painting as a part of the automatic production of door panels, there is no need to interrupt the production line to perform a separate painting process on the door panels during production, reducing costs. A painting position or automated painting equipment can be added near the production line set in this structure to cooperate with the painting. A painting sensor is set in the transportation device. When the door panel is transported to a specified position through the transportation device, the transportation device stops transporting, and the door panel is lifted and flipped with the cooperation of the door panel bracket, the lifting device, and the flipping device to cooperate with the painting.

[0008] Preferably, for a door panel flipping structure as described above, the inner bracket includes a main bracket, a sub-bracket, and a rotating beam. The main bracket is provided with two support rods, the sub-bracket is provided with one support rod, both ends of the rotating beam are placed on both sides in the width direction of the outer frame, the sub-bracket is movably connected to the rotating beam. When in the flipping position, one end of the sub-bracket is separated from the transportation surface with the cooperation of the rotating beam and the lifting device, and at the same time, the main bracket is connected to the flipping device and separated from the transportation surface with the cooperation of the lifting device. The support rod of the sub-bracket coincides with the rotating shaft of the door panel in the flipping position, and the main bracket cooperates with the flipping device to perform flipping.

[0009] During the flipping process, the flipping device controls the two support rods of the main bracket to make the door panel rotate around the support rod of the sub-bracket. Selecting one-way control for rotation instead of two-way avoids the situation of out-of-sync when rotating in two lines and also reduces costs.

[0010] Preferably, for a door panel flipping structure as described above, the lifting device includes a telescopic part and a base. The number of bases is four, and each base is provided with a telescopic part. Two of the telescopic parts near the main bracket cooperate with the flipping device, and the other two telescopic parts are movably connected to both ends of the rotating beam.

[0011] The setting of the base is used to support the flipping movement of the door panel. A counterweight can be added to the base or the base can be connected to the ground. The telescopic part is used to cooperate with the main and sub-brackets at both ends of the door panel to lift to obtain a suitable rotation space.

[0012] Preferably, for a door panel flipping structure as described above, the lifting device further includes a lifting beam. Both ends of the lifting beam are connected to the two telescopic parts near the main bracket, and the middle part of the lifting beam is connected to the flipping device.

[0013] Preferably, for a door panel flipping structure as described above, avoidance parts are provided on both sides of the lifting beam, and the avoidance parts cooperate with the transportation rail.

[0014] The setting of the lifting beam and the cooperation of the avoidance part enable the door panel to effectively avoid the transportation track during the flipping process, reducing the interference between devices and improving the smoothness of the flipping action.

[0015] Preferably, in the door panel flipping structure described above, clamping grooves are provided at both ends of the rotating beam. The clamping grooves are through lateral openings. Clamping parts are provided at the tops of two telescopic parts near the rotating beam, and the clamping parts cooperate with the clamping grooves.

[0016] Since the clamping grooves are through lateral openings and the door panel is horizontally transported, the through lateral openings facilitate the clamping of the clamping parts with the clamping grooves. The length of the clamping parts is longer than that of the clamping grooves to avoid falling during the lifting process.

[0017] Preferably, in the door panel flipping structure described above, the flipping device includes flipping support rods, a flipping table, a flipping bracket, and a flipping driving device. Flipping clamping parts are provided at the ends of the flipping support rods. The flipping driving device is electrically connected to the flipping table. The flipping support rods are arranged on the flipping table. The flipping table is rotatably connected to the flipping bracket. The flipping bracket is fixed on the lifting beam. The flipping clamping parts are provided with upwardly opening grooves.

[0018] The integrated design of the flipping support rods, the flipping table, the flipping bracket, and the flipping driving device realizes the automatic flipping of the door panel, reduces manual operation, and improves production efficiency and operation simplicity. The flipping clamping parts are provided with upwardly opening grooves, and the grooves cooperate with the support rods of the main bracket. The flipping support rods and the flipping table can be adjusted to adapt to door panels of different sizes.

[0019] Preferably, in the door panel flipping structure described above, the upper part of the upwardly opening groove provided in the flipping clamping part is V-shaped, and the lower part is semi-circular.

[0020] The upper part of the groove of the flipping clamping part being V-shaped creates convenience for the cooperation with the main bracket during the lifting of the flipping device, making it easier for the support rods of the main bracket to be inserted into the flipping clamping parts. The lower part of the groove of the flipping clamping part being semi-circular facilitates the rotation of the support rods during the flipping of the door panel.

[0021] Preferably, in the door panel flipping structure described above, the outer frame is provided with a lifting avoidance part.

[0022] The design of the lifting avoidance part provides space for the operation of the flipping device, enabling the outer frame to adapt to different door panel sizes and shapes during the flipping process, and improving the versatility and adaptability of the device.
