Description

Technical Field

[0001] This invention belongs to the field of panel spraying technology and relates to a method for protecting panels before spraying. Background Technology

[0002] During the processing of metal sheets, marking grooves containing symbols, text, letters, and numbers are typically cut into the surface to serve as prompts, warnings, or to facilitate operation. To make these markings more visible and durable, they are usually painted for better clarity. During painting, non-painted areas must be protected, and only the marking areas are painted, requiring precise part positioning. Currently, the method for protecting sheet metal before painting typically involves manually cutting protective film with the corresponding lettering. Without any auxiliary positioning aids, the marking area is determined visually, and the protective film is then pasted onto the metal sheet. This method is inaccurate and inefficient. Furthermore, removing the protective film and any residual adhesive after painting is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a method for protecting sheet metal before painting. This method solves the problems of poor accuracy and low efficiency in adhering to the protective film on the metal sheet by visually judging the positioning mark area without any auxiliary positioning, and the time-consuming and laborious process of removing the protective film and residual adhesive after painting.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A method for protecting a panel before spraying, characterized in that it includes a frame, a placement platform fixedly connected to the frame, first push rod motors symmetrically arranged on both sides of the placement platform, a first clamping plate fixedly connected to the push rod of the first push rod motor, a second push rod motor fixedly connected to the upper end of the frame, a third push rod motor fixedly connected to the push rod of the second push rod motor, a double push rod motor fixedly connected to the push rod of the third push rod motor, and a second clamping plate fixedly connected to the push rod of the double push rod motor.

[0006] The method for protecting the sheet metal before spraying includes the following steps:

[0007] Step S1: Cut out the corresponding sign block from the paint spraying baffle using a laser cutting machine;

[0008] Step S2: Place the board on the placement table, start the first push rod motor to drive the first clamping plate to move towards the center and clamp the board;

[0009] Step S3: Place the marker block in the marker slot of the board, and then insert the marker hole cut out of the paint spray baffle into the marker block to achieve the positioning of the paint spray baffle;

[0010] Step S4: The second push rod motor drives the third push rod motor and the double push rod motor to come to the top of the plate. The third push rod motor drives the double push rod motor and the second clamping plate to descend. The double push rod motor drives the second clamping plate to clamp the paint spraying baffle. Then the third push rod motor drives the clamped paint spraying baffle to rise and remove the marker block, thus realizing the positioning of the paint spraying baffle.

[0011] Step S5: The third push rod motor drives the already positioned paint baffle to move up and down, thus achieving repeated masking protection;

[0012] Step S6: After completing the masking protection before painting, the second push rod motor and the third push rod motor drive the paint spraying baffle to the cleaning area to wash away the masked paint.

[0013] Step S7: Dry the cleaned and painted panels.

[0014] In the above-mentioned protection method for the panels before spraying, a clean water tank and a waste water tank are fixedly connected to the frame, and a spray nozzle is provided on the clean water tank.

[0015] In the above-mentioned protection method for the plate before spraying, the surfaces of the first clamping plate and the second clamping plate are provided with rough texture.

[0016] In the above-mentioned protection method for the panels before spraying, a hot air blower is fixedly connected to the frame.

[0017] In the above-mentioned method for protecting the panels before spraying, in step S7, the painted panels are dried with hot air at (80±5)℃.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The spray paint baffle is positioned accurately and quickly using a marker block, and a second clamping plate prevents it from shifting, allowing for repeated spray painting and masking of the workpiece. Cleaning and drying the spray paint baffle prevents paint from sticking to other parts of the workpiece. The spray paint baffle can be reused, eliminating the need to remove the protective film and adhesive. Attached Figure Description
