Description

Technical Field

[0001] The invention relates to the technical field of manufacturing equipment, and in particular to an automatic film-sticking assembly production line for a light guide plate of a washing machine. Background Art

[0002] When applying film to the internal functional parts of the washing machine control panel assembly, most of the time, the positioning structure is designed through the product structure, and the left and right anti-error structures need to be designed, and then the assembly is performed by manual film application. Obviously, this method is not only inefficient, but also the quality is affected by the skills of the employees, is not stable enough, and has high requirements for operators. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic film-sticking assembly production line for a washing machine light guide plate, which has the characteristics of high production efficiency and relatively stable assembly quality.

[0004] The technical solution adopted by the present invention is: an automatic film-sticking assembly production line for a washing machine light guide plate, which is used to stick the film on the light guide plate. The production line includes: an injection mold, in which the light guide plate is injection-molded; at least two supporting jigs arranged side by side; an assembly jig; two sets of tooling boxes, in which purchased films are pre-placed; a CCD detection device; a film-tearing tool; a PLC; a film pressing roller; a robot; and, the CCD detection device signal is connected to the PLC; the PLC signal is connected to the robot; the film pressing roller and the assembly jig are matched, and the robot is matched with the injection mold, the supporting jig, the assembly jig, the tooling box, and the film-tearing tool.

[0005] The production line also includes a conveying line.

[0006] Compared with the prior art, the advantages of the present invention are: high production efficiency and stable assembly quality. The automatic film pasting assembly production line for the washing machine light guide plate of the present invention mainly takes out the product from the mold through a six-axis robot, collects the purchased film at the same time, and automatically assembles after finding the reference through CCD visual positioning. It can also actively prevent errors, has low requirements for personnel, and is not affected by whether the incoming materials of the assembly parts are consistent, so that the production efficiency is high and the assembly quality is stable.

[0022] For example, see Figures 1 to 4 As shown: The automatic film pasting assembly line for the light guide plate of a washing machine is used to paste the film on the light guide plate. The shape of the film is generally rectangular, almost symmetrical, and the only difference in appearance is the shape of the holes at both ends, one is a round hole and the other is an elliptical hole. This makes it easy to distinguish the orientation during assembly, so that the sticky glue on the back of the film can be covered on the correct position on the light guide plate as required. That is, it is crucial to prevent the problem of wrong pasting.

[0023] Specifically:

[0024] The production line includes:

[0025] (1) An injection mold 10 in which the light guide plate is injection molded.

[0026] (2) At least two supporting jigs 20 are arranged side by side. The reason why there are at least two supporting jigs 20 is that the light guide plates placed on them and still at a certain temperature can dissipate heat in turn, and the other light guide plates can be taken away in time for subsequent processing after the temperature drops.

[0027] (3) Assembly jig 30. That is, the light guide plate can be placed on the assembly jig 30 for assembly operations such as film lamination.

[0028] (4) Two sets of tooling boxes 40. The purchased films are placed in advance in the tooling boxes 40. Each set of tooling boxes 40 is generally two arranged side by side to avoid stopping the machine when the films placed therein are used or when the purchased films need to be replenished.

[0029] (5) CCD detection device 50.

[0030] (6) Film tearing tool 60.

[0031] (7)PLC.

[0032] (8) Lamination roller 70.

[0033] (9) Robot arm 80, which is generally a six-axis robot.

[0034] More specific:

[0035] The signal of the CCD detection device 50 is connected to the PLC, and the signal of the PLC is connected to the robot 70. That is, the position and orientation information of the film can be obtained through the CCD detection device 50, so as to control the precise movement of the robot 80.

[0036] The laminating roller 70 is matched with the assembly jig 30. That is, the laminating roller 70 is located on the upper part of the assembly jig 30, and can roll the components located on the assembly jig 30 after rolling.

[0037] The robot arm 80 is matched with the injection mold 10, the carrying fixture 20, the assembly fixture 30, the tool box 40, and the film tearing tool 60. That is, the robot arm 80 can perform corresponding operations on the products or components located in the injection mold 10, the carrying fixture 20, the assembly fixture 30, the tool box 40, and the film tearing tool 60.

[0038] Optimized:

[0039] The production line also includes a common conveyor line 90 such as a belt type.

[0040] The working process of the present invention is as follows: the robot 80 takes out the plastic product, that is, the light guide plate which is still in a relatively hot state, from the injection mold 10 according to the program design, and puts it on a certain supporting fixture 20 for cooling. After the cooling is completed, the next operation can be carried out. Then, the robot 80 takes out the light guide plate which has been cooled and places it on the assembly fixture 30. The purchased film is placed in the tool box 40 in advance. After one of the tool boxes 40 does not have the purchased film, the robot 80 can take out the purchased film from another tool box 40, and the operation is carried out in turns, so that the machine will not stop due to the lack of the purchased film. After the robot 80 takes the purchased film, it is placed in the detection range of the CCD detection device 50. The CCD detection device 50 detects the appearance, error-proof position and other issues of the purchased film. After it is correct, the robot 80 moves the film to the film tearing tool 60 to tear the paper. There is a protective film on the back of the purchased film, which needs to be torn off when in use. After the robot 80 has finished tearing the separation paper, it will release the gripper and the separation paper will fall off freely. The robot 80 will move the film that can be assembled to the assembly fixture 30, and then the robot 80 will leave. The film pressing roller 70 will operate to compact the film to ensure that the film and the product can be effectively bonded. Finally, the robot 80 will take out the product and put it on the conveyor line 90 for transportation and packaging.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
