The present invention relates to a cell phone case automatic coating method, more specifically, a coating, drying operation is carried out while the jig through a plurality of cell phone cases are transferred along the installed conveyor, thereby reducing the waste of raw materials and manpower while increasing productivity The present invention relates to a cell phone case automatic coating method.

In general, as mobile phones are recognized as necessities of life and demand is rapidly increasing, mass production is inevitable, and as the production of cell phone cases is also mass-produced, the outer surface of the case must be coated in various colors according to the production order of the case.

The conventional coating method is to mount one cell phone case on one jig and rotate it, and production logistics is progressed. The worker attaches the cell phone case to the jig individually and flows along the line to remove static electricity and remove particles. A ventilation purifier equipped with spray guns to coat the undercoat is reached, and the spray booth is closed, and the cell phone case after the first coating enters the IR drying room and is dried. The finished cell phone case arrives in the second spray booth for the second coating and performs the second coating. The case after the second coating is dried again into the IR drying room, and after the drying is completed, the UV coating is carried out to the third spray booth for UV application. After the UV coating, the case is dried again by entering the IR drying room, and the drying process is performed by UV lamp for 3 to 5 minutes as the final process of drying, and the mobile phone case which has been completed along the line is extracted by the worker. .

UV coating is optional depending on the product produced. In the case of secondary coating, the UV coating is omitted, and in the case of UV coating, the secondary coating is often omitted. Primary coating or UV coating is optionally performed.

In the conventional production line as described above, the length of the line is long, the power consumption for driving it and the length of the line are long, so that the demand of the jig is also increased, and to ensure the shape of the jig transferred individually and the working space of the worker, Because the gap between them is maintained, a large number of spray guns and a large amount of coating liquid or coating liquid are unnecessarily consumed for the application of the three-dimensional cell phone case in the spray booth without defect. Uncoated paint is dispersed in the air to provide a major cause of other environmental pollution, and it is an additional investment cost and cost increase factor that requires separate purification costs and facilities to clean such polluted air. Due to the longer production line, the installation surface of equipment and equipment As the number of enemies increases and occupies a relatively large space, the initial investment cost and maintenance cost of preparing a large factory building area increases, so the driving method of the line, the casting of the line, the structure of the jig, the structure of the spray booth, the spray This necessitated a serious need to comprehensively improve the shape change and line configuration of each facility.

The present invention for solving the above problems by compactly coating and drying a plurality of mobile phone cases at the same time to configure a series of production lines to produce a finished product, a mobile phone that can reduce the number of people, waste of raw materials, product productivity An object of the present invention is to provide an automatic coating method of the case.

As described above, the present invention mounts a plurality of cell phone cases 100 on one jig 10 in a batch type, and when placed on the conveyor 100, the jig 10 is transferred in an in-line type. ) Enters the static elimination and dust removal step (S2), it is detected by the first rotation step (S2-1) and at the same time the brush bristles 24 in contact with the mobile phone case 100 to remove static electricity or particles, etc. After passing through the brush step (S2-2), and then moving a predetermined distance or by spraying the air at the location through the air supply step (S2-3) to remove dust, foreign matters and the like is transported along the conveyor (100).

In the process of the brush and the air supply step (S2-2, 3), by the suction step (S2-4) is to discharge the particles, dust, foreign matters, etc. attached to the mobile phone case 100 to the outside .

When the mobile phone case 100 of the jig 10 transferred along the conveyor 100 enters the interior of the work room B of the first coating step S3, the mobile phone case 100 detects this and first enters the rotation step S3-1. By the operation of the spray gun 31 using the robot according to the rotation and the set program at the same time, after finishing the first undercoat coating, it is transported along the conveyor (100).

As described above, when the cellular phone case 100 of the first coated jig 10 enters the interior of the work room B of the IR drying step S4, the mobile phone case 100 is detected and rotated by the rotation induction step S4-1. After drying while moving along the (100), it is transported along the conveyor (100).

Subsequently, when the mobile phone case 100 of the dried jig 10 enters the interior of the work room B of the vibration suppression step S5, the mobile phone case 100 is rotated by the rotation step S5-1 and sprays air at the same time. After removing dust, foreign matters, etc. of the case 100, it is transported along the conveyor (100).

When the cell phone case 100 thus cleaned enters the interior of the workroom B of the secondary coating machine, it detects this and performs the second top coating in the same manner as the primary coating method, and UV coating is possible in this process. .

Such a present invention is equipped with dozens of mobile phone case 100, compared with the prior art multiply the number of mobile phone case 100 mounted on the jig 10 by reducing the interval of the jig 10 of the prior art one jig Since it can be transported to (10), the length of the conveyor (100) can be reduced to a few tenths. This saves substantial floor space and initial investment.

As described above, according to the present invention, a plurality of mobile phone cases 100 are mounted on one jig 10, and the number of mobile phone cases 100 mounted on the jig 10 is multiplied by the conventional jig (10). 10) It can be transported with one jig (10) by reducing the distance, so the transport length can be reduced to tens of minutes. Therefore, the installation area and initial investment of coating equipment can be reduced.

In addition, the present invention is a batch type of a plurality of mobile phone cases in one jig, so that one or several spray guns at the same time or several at a time with a single jig at the same time or selective order is made, unnecessary coating liquid You can stop the waste.

In addition, the present invention by installing the coating liquid collector to prevent the spraying of the coating liquid in the first and second coating steps to collect the paint dust scattered in the air, reducing the environmental pollution and its processing cost due to the scattering of unnecessary paint You can do it.

In addition, the present invention is to selectively spray the coating liquid supplied to the spray gun to perform the secondary coating and UV coating step by a program selectively, so that it can be parallel to a single facility, and thus the length of the line By reducing the installation area and initial investment costs.

As described above, the embodiment of the efficient automatic cell phone case coating method according to the present invention, but the scope of the present invention is not limited to this, crazy about all the technical ideas of the scope equivalent to those described in the claims. Will be said.
