[0016] Example 1

[0017] like Figures 1 to 4 As shown, the present invention proposes a door panel assembly and painting line, including a conveying mechanism, a transfer platform, and a chain conveyor belt mechanism 6. The conveying mechanism consists of a second frame 103 and multiple sets of detachably connected first frames 1. One end of the first frame 1 is equipped with a docking rod 101, and the other end of the first frame 1 is correspondingly provided with a docking interface. The docking rod 101 is inserted into the docking interface to facilitate quick alignment of two adjacent sets of first frames 1 for subsequent connection. Multiple sets of conveying rollers 102 are rotatably connected to both the first frame 1 and the second frame 103. The multiple sets of conveying rollers 102 on the first frame 1 are driven to rotate synchronously by a drive mechanism installed on the side wall of the first frame 1. The drive mechanisms on the multiple sets of first frames 1 are controlled to start and stop synchronously by a controller. The drive mechanism consists of a motor-driven chain drive assembly. The second frame 103 is detachably connected to the adjacent first frame 1. The transfer platform is distributed between the second frame 103 and the adjacent set of first frames 1. The transfer platform consists of a lifting frame and a mechanism installed on the lifting frame. The third frame 3 consists of multiple sets of conveyor rollers 302 rotatably connected to the third frame 3 and two sets of first conveyor belts 301 symmetrically mounted on the multiple sets of conveyor rollers 302. The multiple sets of conveyor rollers 302 are driven to rotate synchronously by a drive mechanism mounted on the third frame 3. The drive mechanism consists of a motor-driven chain drive assembly. The lifting frame is distributed between the second frame 103 and the adjacent first frame 1. The first conveyor belts 301 correspond to the output end of the first frame 1 and the input end of the second frame 103. A set of photoelectric sensors 5 are provided on the output end of the first frame 1 near the second frame 103 and on the second frame 103 to detect whether the door panel has passed to the appropriate position. Multiple sets of chain conveyor belt mechanisms 6 are provided. The chain conveyor belt mechanisms 6 are distributed at the output end or input end of the transfer platform. The width of the second conveyor belt in the chain conveyor belt mechanism 6 is greater than the width of the first conveyor belt 301, and the width of the second conveyor belt is greater than the distance between the two sets of first conveyor belts 301.

[0018] Furthermore, docking components are provided between the second frame 103 and the adjacent first frame 1, as well as between two adjacent sets of first frames 1. The docking components include a connecting rod 2, a mounting base 202, and a plug rod 204. The connecting rod 2 is detachably connected to one end of the first frame 1 or the second frame 103 by bolts, and a slot 1 201 is provided on the connecting rod 2. The mounting base 202 is detachably connected to the other end of the first frame 1 or the second frame 103 by bolts, and a slot 203 matching the connecting rod 2 is provided on the mounting base 202. The plug rod 204 slides along the height direction of the mounting base 202 and is elastically connected to the mounting base 202. The plug rod 204 is slidably inserted into the slot 203, and the insertion end of the plug rod 204 matches the slot 1 201. A spring 205 is sleeved on the plug rod 204, one end of the spring 205 is connected to the plug rod 204, and the other end of the spring 205 is connected to the mounting base 202.

[0019] Furthermore, two sets of docking mechanisms are symmetrically arranged between the second frame 103 and the first frame 1, as well as between two adjacent sets of first frames 1. The length of the connecting rod 2 on the second frame 103 is greater than the length of the connecting rod 2 on the first frame 1, which facilitates the separation of the second frame 103 and the first frame 1 and makes it convenient for the distribution of the transfer platform.

[0020] Furthermore, the lifting frame includes a movable base 4 and a telescopic rod 401; a lifting component is provided between the movable base 4 and the third frame 3, the lifting component is a hydraulic rod, and a self-locking universal wheel is provided at the bottom of the movable base 4 to facilitate movement and limit the telescopic rod 401 installed between the third frame 3 and the movable base 4, and multiple sets of telescopic rods 401 are provided.

[0021] Furthermore, a threaded rod 402 is threadedly connected to the movable base 4, and a guide rod is slidably connected to one side of the threaded rod 402 and located on the movable base 4. An anti-slip seat 403 is installed at the bottom end of the guide rod, and the threaded rod 402 and the anti-slip seat 403 are rotatably connected by a bearing.

[0022] In this embodiment, the insertion rod 204 on the first frame 1 is slid upward along the mounting base 202 to compress the spring 205 until the insertion end of the insertion rod 204 is far away from the slot 203. Then, the docking rod 101 on another set of first frames 1 is inserted into the docking interface on this set of first frames 1, so that the two sets of first frames 1 are quickly aligned and the connecting rod 2 is quickly inserted into the slot 203. The insertion rod 204 is released and, under the elastic force of the spring 205, the insertion rod 204 is inserted into the slot 201 on the connecting rod 2, and then the connecting rod 2 is connected to the mounting base 202, thereby splicing two adjacent sets of first frames 1. According to the needs of the assembly painting line, multiple sets of first frames 1 can be quickly spliced ​​for use. Then, the second frame 103 is spliced ​​with the adjacent first frame 1 in the same way to complete the assembly of the conveying mechanism. Multiple sets of conveying mechanisms can be assembled according to the needs of use and evenly distributed in the workshop.

[0023] The third frame 3 is moved to the space between the second frame 103 and the first frame 1 using casters, and the position of the transfer platform is adjusted to be suitable so that the third frame 3 corresponds to the output end of the first frame 1 and the output end of the second frame 103. Then, the chain conveyor belt mechanism 6 is distributed at the output or input end of the transfer platform. The threaded rod 402 is rotated, and under the guidance of the guide rod, the threaded rod 402 moves downward along the movable base 4 until the anti-slip seat 403 abuts against the installation ground, which further improves the installation stability of the transfer platform and avoids relative sliding.

[0024] The door panel is placed on the conveyor mechanism. The controller activates multiple sets of drive mechanisms to drive multiple sets of conveyor rollers 102 to rotate synchronously and convey the door panel. When the door panel moves between the second frame 103 and an adjacent set of first frames 1, the photoelectric sensor 5 detects the door panel's entry and transmits the detection information to the controller. The controller then activates the lifting mechanism to drive the third frame 3 to rise until the first conveyor belt 301 contacts the door panel and lifts it away from the conveyor rollers 102. The controller then activates the drive mechanism to drive multiple sets of conveyor rollers 302 to rotate synchronously, which in turn drives two sets of first conveyor belts 301 to rotate, conveying the door panel toward the chain conveyor belt mechanism 6 at the output end until the door panel enters the chain conveyor belt mechanism 6. Workers standing on both sides of the chain conveyor belt mechanism 6 can assemble and paint the door panel for different processes, avoiding the multiple handling and transfer of the door panel in the traditional method, saving physical strength and improving work efficiency.

[0025] Example 2

[0026] like Figure 2As shown, the door panel assembly and painting line proposed in this utility model, compared with Embodiment 1, also includes a sorting component. The sorting component is provided in multiple sets, and the multiple sets of sorting components are respectively set at the output end of a set of first frames 1 near the second frame 103 and the input end of the chain conveyor belt mechanism 6. The sorting component consists of two sets of support seats 7 and an adjusting plate 701 installed on the support seats 7 through a telescopic member. The telescopic member is a hydraulic rod. The support seats 7 are installed on the first frame 1 or the chain conveyor belt mechanism 6 by bolts. The adjusting plate 701 is distributed above the conveyor roller 102 or above the second conveyor belt in the chain conveyor belt mechanism 6.

[0027] In this embodiment, the photoelectric sensor 5 monitors the passage of the door panel on the first frame 1 or the third frame 3 in real time, and transmits the detection information to the controller. The controller then activates the corresponding two sets of telescopic components to drive the corresponding adjusting plates 701 to move closer to each other, thereby aligning and tidying the door panels on the conveyor roller 102 or the chain conveyor belt mechanism 6. This prevents the door panels from tilting into the third frame 3 or onto the chain conveyor belt mechanism 6, improving conveying efficiency and facilitating subsequent assembly of the door panels by workers.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
