Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically to a metal product electrophoretic coating robot. Background Technology

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, and stainless steel and similar everyday metal products. With social progress and technological development, metal products are increasingly widely used in industry, agriculture, and all aspects of people's lives, creating ever-increasing value for society.

[0003] During the processing of metal products, electrophoretic coating is often required. During electrophoretic coating, a robotic arm is used to hold the metal products. After the robotic arm removes the metal products from the electrophoretic solution, the gripping end of the robotic arm will be covered with electrolyte. The robotic arm cannot promote the removal of the electrolyte from the surface of the gripper in time, which leads to corrosion of the gripping end of the robotic arm. In addition, the electrolyte will drip randomly to the outside of the electrophoretic pool during the movement of the robotic arm, resulting in waste. Utility Model Content

[0004] The purpose of this utility model is to provide a robotic arm for electrophoretic coating of metal products to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a robotic arm for electrophoretic coating of metal products, comprising a robotic arm body, a connecting seat, and a robotic gripper for holding the metal products, and further comprising:

[0006] A movable plate is rotatably connected to the front and rear sides of the connecting seat. A connecting plate is movably connected inside the movable plate. A collecting plate is fixed at the other end of the connecting plate. A drive structure for driving the movable plate to rotate is provided on the surface of the connecting seat.

[0007] A first electric push rod is fixed on one side of each of the two movable plates facing each other, and the output end of the first electric push rod is fixed to one side of the collecting plate.

[0008] A folding plate is fixed to the left side of the connecting seat, and a fixing plate is hinged to the other end of the folding plate. Several fans are installed inside the fixing plate.

[0009] A second electric push rod is disposed through the bottom of the folded plate. A groove is provided on the right side of the fixed plate, and a slider is slidably connected inside the groove. The output end of the second electric push rod is rotatably connected to the inside of the slider.

[0010] Preferably, the drive structure includes a motor fixed to the surface of the connecting seat, a first bevel gear fixed to the output shaft of the motor, and a second bevel gear fixed to the surface of the rotating shaft of the front movable plate, wherein one side of the first bevel gear meshes with one side of the second bevel gear.

[0011] Preferably, the outer surface of the movable plate is provided with a moving groove, and a moving block is slidably connected inside the moving groove. One end of the moving block is fixed to one side of the connecting plate.

[0012] Preferably, the inner side of the collecting plate is provided with a collecting groove, and the bottom surface of the collecting groove is inclined downwards.

[0013] Preferably, limiting plates are fixedly connected to both the front and rear sides of the connecting seat, and the limiting plates are located above the movable plate.

[0014] Preferably, the width of the collecting plate is greater than the maximum length of the mechanical claw when it is open.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] After the clamped metal product is soaked, the drive structure drives the movable plate and the collecting plate to deflect downwards, so that the collecting plate is located below the clamped metal product. This facilitates the collection of liquid dripping from the metal product and the mechanical claw, thus preventing the liquid from dripping randomly and causing waste. At the same time, the second electric push rod applies force to the fixed plate, causing the fixed plate to deflect. This allows the fan to blow the liquid on the surface of the metal product and the mechanical claw, thereby improving the dripping efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 As shown, a metal electrophoretic coating robot includes a robotic arm body 1. A connecting seat 2 is provided at the other end of the robotic arm body 1, and a mechanical claw 3 for gripping the metal product is provided at the bottom of the connecting seat 2. Movable plates 4 are rotatably connected to both the front and rear sides of the connecting seat 2. A connecting plate 5 is movably connected inside the movable plate 4. A collecting plate 6 is fixed to the other end of the connecting plate 5. A driving structure 8 for rotating the movable plates 4 is provided on the surface of the connecting seat 2. A first electric push rod 7 is fixed to one side of each of the two movable plates 4 facing each other, and the output end of the first electric push rod 7 is fixed to one side of the collecting plate 6. A folded plate 9 is fixedly connected to the left side of the connecting seat 2. A fixed plate 10 is hinged to the other end of the folded plate 9, and several fans 11 are provided inside the fixed plate 10. A second electric push rod 12 is provided through the bottom of the folded plate 9. A sliding groove 13 is provided on the right side of the fixed plate 10, and a slider 14 is slidably connected inside the sliding groove 13. The output end of the second electric push rod 12 is rotatably connected to the inside of the slider 14.

[0024] The drive structure 8 includes a motor 81, a first bevel gear 82, and a second bevel gear 83. The motor 81 is fixed to the surface of the connecting seat 2. The output shaft of the motor 81 is fixed to one side of the first bevel gear 82. One side of the first bevel gear 82 meshes with one side of the second bevel gear 83. The interior of the second bevel gear 83 is fixed to the rotating shaft surface of the front movable plate 4. Thus, when the movable plate 4 is rotated, the motor 81 can be started, which will drive the first bevel gear 82 to rotate and simultaneously drive the second bevel gear 83 to rotate, thereby causing the movable plate 4 to deflect at an angle.

[0025] The outer surface of the movable plate 4 is provided with a moving groove 15, and a moving block 16 is slidably connected inside the moving groove 15. One end of the moving block 16 is fixed to one side of the connecting plate 5, so as to provide auxiliary limit for the connecting plate 5 and prevent it from moving excessively.

[0026] The inner side of the collecting plate 6 is provided with a collecting groove 17, and the bottom surface of the collecting groove 17 is inclined downwards. This not only allows the dripping liquid to be collected, but also allows the liquid inside the collecting plate 6 to flow into the electrophoresis pool after the collecting plate 6 is positioned above the electrophoresis pool.

[0027] Limiting plates 18 are fixedly connected to both the front and rear sides of the connecting seat 2, and the limiting plates 18 are located above the movable plate 4. This can limit the position of the movable plate 4 after it rotates upward, preventing it from rotating excessively and colliding with the motor 81.

[0028] The width of the collecting plate 6 is greater than the maximum length of the mechanical claw 3 when it opens, so that the collecting plate 6 can better collect the dripping liquid and prevent the liquid from being wasted.

[0029] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0030] Working principle: In use, the robotic arm body 1 can be moved to the position of the electric pool, and then the mechanical claw 3 can be used to clamp the metal product. The clamped metal product is then immersed in the electric pool. After immersion, the mechanical claw 3 will move upward and pull the metal product out of the electric pool. Then, the drive structure 8 drives the movable plate 4 to rotate, and drives the collection plate 6 to rotate below the clamped metal product. When the collection plate 6 is deflected, if the size of the clamped metal product is high, the first electric push rod 7 can be activated to move the collection plate 6, thereby expanding the length between the connecting plate 5 and the movable plate 4. When the collection plate 6 is below the clamped metal product, the liquid dripping from the surface of the metal product will fall into the movable block 16 for collection. At the same time, as the robotic arm body 1 moves, the second electric push rod 12 can be activated to drive the fixed plate 10 to swing back and forth, so that the fan 11 blows the liquid on the surface of the metal product and the mechanical claw 3, making the liquid drip faster.
