Description

Technical Field

[0001] This utility model relates to the field of coating machine cleaning technology, and in particular to a device for automatically gripping multi-shaped solvent-resistant cleaning fixtures. Background Technology

[0002] Coating performance is one of the most important characteristics of pre-coated steel sheets. It is related not only to the production process but also to the quality of the coating itself. Therefore, the cleanliness of the coating within the rollers and paint trays is a key factor affecting the coating quality of pre-coated steel strips.

[0003] Currently, coating unit cleaning is done manually or with the assistance of other personnel. Because most color coating paints are toxic and harmful to the environment and human health, the coating machine is located inside the painting chamber. Furthermore, the color coating production process requires applying different types and / or colors of paint according to different color coating requirements, necessitating personnel entering the painting chamber for operation. When changing the type and / or color of paint, paint cleaning agents are used to clean areas such as the feed rollers, coating rollers, and paint trays before adding new paint to the trays. Since the cleaning agents are harmful substances that pose a significant risk to human health, and the cleaning work is time-consuming and involves numerous tasks, paint cleaning is a high-risk process. Currently, before changing paint, manual cleaning requires wearing protective equipment according to the work instructions before entering the painting chamber.

[0004] Therefore, it is necessary to provide an automatic gripping device for multi-shaped solvent-resistant cleaning fixtures, which is installed on a cleaning robot to grip the multi-shaped solvent-resistant cleaning fixtures to clean the feed rollers, coating rollers and paint trays of a coating machine.

[0033] Now see Figures 1 to 5This utility model provides an automatic gripping device for solvent-resistant cleaning fixtures of various shapes, including a positioning gripper 1, a gripper cylinder 2, and a first mounting plate 4. The gripper cylinder 2 is mounted on the first mounting plate 4, and the positioning gripper 1 is connected to the gripper cylinder 2. The positioning gripper 1 includes two symmetrically arranged grippers. The gripper cylinder 2 drives the two grippers to move closer to or away from each other. Each gripper includes a connecting block 11 and a clamping block 12. The connecting block 11 is L-shaped, with its long side connected to the gripper cylinder 2 and its short side connected to the clamping block 12. The clamping block 12 is inverted T-shaped, and its top is fixed to the connecting block 11. The bottom of the clamping block 12 is provided with positioning holes 121 at both ends; the first mounting plate 4 is provided with a guide pipe 3, which is connected to the cleaning agent supply device through a pipe; the cleaning fixture 7 is provided with a positioning pin 71 that matches the positioning hole 121 and a liquid supply connector 72 that matches the guide pipe 3. When the cleaning fixture 7 is gripped, the guide pipe 3 is inserted into the liquid supply connector 72. The positioning hole 121 and the positioning pin 71 are correspondingly set. The gripper cylinder 2 drives the two grippers to approach each other, so that the positioning pin 71 passes through the positioning hole 121. At the same time, the clamping block 12 clamps the cleaning fixture 7, so as to achieve reliable positioning and clamping of the cleaning fixture 7.

[0034] In some embodiments, there are two guide pipes 3, which are fixed on the first mounting plate 4 and symmetrically arranged on both sides of the gripper cylinder 2.

[0040] In some embodiments, the second mounting plate 6 is made of aluminum alloy, which is lightweight and reduces weight.

[0041] In practice, the robotic arm of the cleaning robot moves above the supply device on which the cleaning fixture 7 is placed, and moves down to insert the guide tube 3 into the liquid supply connector 72 of the cleaning fixture 7 to be gripped. At the same time, the positioning hole 121 is set to correspond to the positioning pin 71 of the cleaning fixture 7. The gripper cylinder 2 drives the two grippers to approach each other, so that the positioning pin 71 passes into the positioning hole 121, and the clamping block 12 clamps the cleaning fixture 7.

[0042] The cleaning fixture 7 includes various types, such as scraper fixture, scraper spray fixture and wiping fixture. The three have different shapes and structures, but the clamped part that contacts the clamping block 12 has the same structure. They are all provided with positioning pin 71 and liquid supply connector 72 in the same position to match the gripping device.

[0043] In summary, the present invention provides an automatic gripping device for multi-shaped solvent-resistant cleaning fixtures. The device uses a gripper cylinder 2 to drive a positioning gripper 1, causing two symmetrically arranged grippers on the positioning gripper 1 to move closer or further away from each other for clamping. Each gripper includes a connecting block 11 and a clamping block 12. The long side of the connecting block 11 is connected to the gripper cylinder 2, and the top of the clamping block 12 is connected to the connecting block 11. Positioning holes 121 are provided at both ends of the bottom of the clamping block 12. The cleaning fixture 7 is provided with positioning pins 71 that match the positioning holes 121. When gripping the cleaning fixture 7, the positioning holes 121 and positioning pins 71 are aligned.
