Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a gantry type automatic electrophoretic coating equipment. Background Art

[0002] Automatic electrophoretic coating is an advanced coating technology that uses electric current to evenly deposit electrophoretic paint on the surface of the object to be coated, forming a dense coating film with strong adhesion, high hardness, and smoothness. At the same time, automatic electrophoretic coating is also highly automated and can be stably and reliably carried out on a large scale, thereby improving production efficiency and reducing production costs.

[0003] At present, a Chinese patent discloses a gantry-type vertical electrophoresis tank (publication number CN210916303U). The utility model facilitates the lifting and lowering of the placement tank through a motor, a main shaft, a winding wheel and a connecting rope. The placement tank facilitates the direct placement of the workpiece, avoiding the need for an additional fixing structure to fix it, simplifying the device structure and reducing the cost of use.

[0004] Since the above device places the workpieces into the electrophoresis tank in a centralized manner through the placement tank, and since the placement tank is open in design, when workpieces such as plastics that are usually less dense than the electrophoresis liquid are required to be electrophoresed, the workpieces are easily floated on the water surface, which makes it difficult for the electrophoresis liquid to cover the entire workpiece surface, increasing the probability of incomplete electrophoresis coverage.

[0005] Therefore, a gantry type automatic electrophoretic coating equipment is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a gantry-type automatic electrophoretic coating equipment in order to solve the above-mentioned problem, which improves the problem that the existing gantry-type automatic electrophoretic coating equipment with the function of limiting the position of the workpiece can only limit the approximate position of the workpiece and is difficult to ensure that the workpiece is immersed in the electrophoretic liquid.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a gantry-type automatic electrophoretic coating equipment, including: a vertical electrophoretic tank, an electric gantry and a heavy-duty winch, the vertical electrophoretic tank is arranged on the inner side of the electric gantry, and the heavy-duty winch is fixedly connected to the top of the electric gantry; a carrying device, the carrying device is fixedly connected to the bottom of the heavy-duty winch, and the carrying device is placed on the inner side of the vertical electrophoretic tank.

[0008] Preferably, the supporting device includes a mesh box fixedly connected to the bottom of the heavy winch, the mesh box is placed on the inner side of the vertical electrophoretic tank, the top of the mesh box is hinged with a mounting plate, the top of the mounting plate is threadedly connected with a threaded column, the bottom of the threaded column passes through the outside of the mounting plate, and the bottom of the threaded column is rotatably connected to a limit plate arranged on the inner side of the mesh box. The supporting device can limit the movable space of the workpiece in the vertical electrophoretic tank, so that the electrophoretic liquid can completely immerse the workpiece in the space, and there is no need to worry about the workpiece floating on the liquid surface, thereby improving the electrophoretic coating effect of the vertical electrophoretic tank on the workpiece.

[0009] Preferably, a guide rod is fixedly connected to the top of the limit plate, and the top of the guide rod passes through the outside of the mounting plate. The guide rod is parallel to the threaded column, which can prevent the limit plate from rotating with the threaded column, thereby achieving the purpose of ensuring the smooth lifting and lowering of the limit plate.

[0010] Preferably, an adjustment handle is fixedly connected to the top of the threaded column, and the corners of the adjustment handle are rounded, which can make it easier for the staff to rotate the threaded column.

[0011] Preferably, a first rubber bellows is fixedly connected between the mounting plate and the limit plate, and the threaded column and the guide rod are both arranged on the inner side of the first rubber bellows, which can cover the threaded column and the guide rod therein, preventing the electrophoretic paint in the electrophoretic fluid from adhering to the surface of the threaded column or the guide rod, thereby ensuring that the limit plate can be raised and lowered normally.

[0012] Preferably, a rectangular groove is provided at the bottom of the mounting plate, and the top of the first rubber bellows is fixedly connected to the inner top wall of the rectangular groove, which can reserve sufficient storage space for the first rubber bellows and avoid damage to the first rubber bellows due to excessive compression.

[0013] Preferably, a sealing plate fixedly connected to the guide rod is rotatably connected to the surface of the threaded column, a second rubber bellows is fixedly connected between the sealing plate and the mounting plate, the threaded column and the guide rod are both arranged on the inner side of the second rubber bellows, and the sealing plate cooperates with the second rubber bellows to cover the threaded column and the guide rod extending above the mounting plate, thereby further preventing the electrophoretic paint in the electrophoretic liquid from adhering to the surface of the threaded column or the guide rod, and further ensuring that the limit plate can be raised and lowered normally.

[0014] Preferably, a rubber sealing ring is fixedly connected to the surface of the limiting plate, and the surface of the rubber sealing ring contacts the mesh box, which can seal the gap between the limiting plate and the mesh box and avoid the possibility of the workpiece being stuck inside the gap.

[0015] Preferably, one end of the net box is fixedly connected with an inclined brace, and the top of the inclined brace is arranged flush with the bottom of the mounting plate. When the staff rotates the mounting plate together with the limit plate to the outside of the net box, the inclined brace can play a role in supporting the mounting plate together with the limit plate, which effectively reduces the pressure at the hinge between the mounting plate and the net box, so that the mounting plate can drive the limit plate to rotate normally.

[0016] The beneficial effects of the utility model are:

[0017] 1. The carrying device can limit the activity space of the workpiece in the vertical electrophoresis tank, so that the electrophoresis liquid can completely immerse the workpiece in the space, and there is no need to worry about the workpiece floating on the liquid surface, thereby improving the electrophoretic coating effect of the vertical electrophoresis tank on the workpiece;

[0018] 2. The staff can adjust the activity space of the workpiece by rotating the threaded column to meet the needs of electrophoretic liquid with different liquid level heights. The rotatable mounting plate design allows the staff to use the limit plate according to needs to meet the processing needs of different workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] When the utility model is in use, the staff first places the workpiece into the mesh box 401.
