Description

Technical Field

[0001] The invention relates to the technical field of film coating equipment, and in particular to a feeding device for a film coating processing line. Background Art

[0002] In the field of vacuum coating technology, commonly used vacuum coating technologies are mostly to use coating processing lines to perform continuous and uninterrupted coating treatment on multiple coating workpieces. The coated workpieces are generally unwound from steel coils and then cut into steel strips of the required length using a steel strip shearing machine and then enter the vacuum coating chamber in turn for coating treatment.

[0003] During the coating process of the coating processing line, it is inevitable that there will be defective workpieces with uneven or incomplete coating, which need to be put back into the coating processing line for re-coating. Since the coating processing line is loaded by unwinding steel coils, the steel strip cannot be loaded in the normal way.

[0004] Therefore, it is necessary to research and develop a loading device that can load materials midway for the coating processing line, so as to solve the problem that the above-mentioned traditional loading device on the coating processing line cannot load the workpiece that needs secondary coating, and because most of the conveying rollers on the coating processing line are passive rolling conveyors, the workpiece loaded midway does not have the inertia of movement, which leads to the inability to drive the conveying rollers to rotate, resulting in difficulty in transportation. Summary of the invention

[0005] The object of the present invention is to provide a feeding device for a coating processing line, so as to solve the problem that the feeding device on the conventional coating processing line cannot feed the workpieces that need secondary coating, and since most of the conveying rollers on the coating processing line are passive rolling conveyors, the workpieces fed in the middle of the feeding do not have the inertia of movement, and thus cannot drive the conveying rollers to rotate, resulting in difficult conveying.

[0006] In order to achieve the above object, the present invention provides a feeding device for a coating processing line, and the specific implementation scheme is as follows:

[0007] A feeding device for a coating processing line comprises a feeding platform and a feeding rack, wherein the end of the feeding platform is connected to a conveying rack, and the feeding rack is movably arranged above the feeding platform; the feeding device also comprises a suction structure and a conveying roller device, wherein:

[0008] The suction structure is installed at the bottom of the loading rack, and the suction structure includes a mounting frame, a lifting cylinder and a material-taking suction cup. The mounting frame is installed at the bottom of the loading rack through the lifting cylinder; the material-taking suction cup is elastically connected to the bottom of the mounting frame;

[0009] The conveying roller device comprises conveying rollers and a driving mechanism. The conveying rollers are rotatably arranged at equal intervals and installed on the conveying frame. The driving mechanism is arranged on the conveying frame and connected to the ends of the conveying rollers to drive the conveying rollers to rotate and convey the workpieces.

[0010] At present, the loading mechanism of the traditional coating processing line loads the steel coils by unwinding them. For the steel strips that need to be repeatedly coated, the original loading method of the coating processing line cannot be used. It is necessary to set up a loading mechanism for clamping the steel strips to clamp the steel strips to the coating processing line for re-coating. At the same time, since most of the conveyor rollers on the coating processing line rotate passively, they need to rely on the transportation inertia of the steel strips on the coating processing line to drive their rotation and transportation. The steel strips loaded in the middle do not have the inertia of movement, resulting in the steel strips being unable to drive the conveyor rollers to rotate, resulting in difficulty in transportation on the coating processing line.

[0011] The feeding device for a coating processing line of the present invention is compared with the prior art. A feeding platform and a conveying frame at the end of the feeding platform are arranged on the coating processing line. The feeding frame above the feeding platform is used to adsorb the external workpiece on the mounting frame through a material taking suction cup, transfer it to the feeding platform, and then enter the conveying frame to be conveyed to the subsequent vacuum coating chamber of the coating processing line for re-coating. A driving mechanism for driving the conveying roller to rotate is arranged on the conveying frame, so that the conveying roller on the conveying frame can rotate by itself, driving the steel belt loaded in the middle to move on the conveying frame. The feeding device has the advantages of simple structure and convenient operation, and effectively solves the problem that the traditional feeding device on the coating processing line cannot feed the workpiece that needs to be coated for the second time, and since most of the conveying rollers on the coating processing line are passive rolling conveyors, the workpiece loaded in the middle does not have motion inertia, which leads to the inability to drive the conveying roller to rotate, resulting in difficulty in conveying.

[0012] As a further improvement of the present invention, the driving mechanism includes a driving motor, a rotating shaft and a plurality of first transmission belts. The rotating shaft is arranged in parallel with the conveying direction at the lower part of the conveying frame and is perpendicular to the conveying rollers on the top surface of the conveying frame. The rotating shaft is connected to the driving motor in a transmission manner. One end of each of the first transmission belts is wound around the rotating shaft, and the other end is wound around one of the conveying rollers, and the plurality of conveying rollers are driven to rotate by the rotation of the rotating shaft.

[0013] Furthermore, several of the conveying rollers are arranged at both ends of the conveying frame, and a second transmission belt is installed at one end of the conveying roller relative to the end on which the first transmission belt is sleeved. The two ends of the second transmission belt are respectively sleeved on the ends of two different conveying rollers to increase the force used for rotation of the conveying rollers at the ends of the conveying frame.

[0014] As a further improvement of the present invention, a plurality of rotatable guide rollers are vertically disposed at both sides of the conveying frame, and the guide rollers are evenly spaced on the conveying frame along the conveying direction.

[0015] Furthermore, a mounting plate which is movable toward the center line of the conveying frame and parallel to the side wall of the conveying frame is provided on the inner side of the conveying frame, and the guide roller is rotatably erected on the mounting plate.

[0016] Furthermore, a correction mechanism is provided at the bottom of the conveying frame, and the correction mechanism includes a correction cylinder and a correction plate. The correction cylinder is vertically fixed on the side wall of the conveying frame, and the correction plate is installed at the piston rod end of the correction cylinder. The correction plate is parallel to and connected to the mounting plate, driving the mounting plate to move.

[0017] As a further improvement of the present invention, at least one buffer mechanism is provided on the mounting frame, and the buffer mechanism can be elastically and telescopically installed between the material picking suction cups, and the bottom of the buffer mechanism extends below the bottom of the material picking suction cups.

[0018] Furthermore, the buffer mechanism includes a connecting rod, an elastic member and a buffer soft rubber member. The connecting rod can be lifted and lowered on the mounting frame, the elastic member is sleeved on the connecting rod, the buffer soft rubber member is installed at the bottom of the connecting rod, and the two ends of the elastic member elastically resist the mounting frame and the buffer soft rubber member respectively.

[0019] As a further improvement of the present invention, it further comprises a support frame, which is mounted above the conveying frame or the loading platform, and the loading frame can be slidably mounted on the support frame.

[0020] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0021] By adopting a driving mechanism consisting of a driving motor, a rotating shaft and multiple first transmission belts, the driving motor is operated to drive the rotating shaft to rotate through the transmission of the gear structure, so that the first transmission belt wrapped around the rotating shaft rotates, driving the conveying roller to rotate on the conveying frame, thereby improving the conveying power of the conveying frame and facilitating the transportation of workpieces loaded midway.

[0022] By arranging a plurality of rotatable guide rollers on the conveyor frame, when the steel belt deviates on the conveyor frame and hits the guide rollers, the guide rollers are forced to rotate, so that the steel belt can stop deviating under the guiding action of the guide rollers and continue to be transported on the conveyor rollers.

[0023] A correction mechanism is arranged on the conveyor frame, and a plurality of guide rollers are arranged at the end of the correction mechanism. When the steel belt continues to be transported under the guidance of the guide rollers, the correction cylinder on the correction mechanism is extended and retracted to drive the correction plate to move, thereby driving the guide rollers to move, and correcting the transportation position of the steel belt to prevent the steel belt from deviating again.

[0024] At least one buffer mechanism is arranged on the mounting frame, and the bottom of the buffer soft rubber part on the buffer mechanism is arranged below the bottom of the material picking suction cup. When the mounting frame clamps the steel belt, the buffer soft rubber part first contacts the steel belt, and the elastic contraction of the elastic part is utilized to buffer the mounting frame, thereby avoiding damage to the mounting frame.
