Workpiece suspension drip prevention support

Abstract

This application discloses a workpiece suspension anti-drip bracket, belonging to the technical field of electrophoretic coating equipment. It includes an electrophoretic coating pool with a guide rail above it. A railcar is slidably connected to the outside of the guide rail. This application achieves horizontal transport of the workpiece by moving the railcar along the guide rail. When the railcar moves directly above the electrophoretic coating pool, an electric telescopic rod controls the connecting block to move downwards, causing the workpiece hanger to descend vertically and immerse itself in the electrophoretic coating pool, thereby achieving electrophoretic coating of the workpiece. After the electrophoretic coating is completed, the electric telescopic rod drives the workpiece hanger to rise vertically away from the electrophoretic coating pool. A motor drives a rotating shaft to rotate, causing a rotating ring to rotate, resulting in the impact block periodically striking the connecting block. This transmits the vibration force to the workpiece hanger, causing it to vibrate at high frequency and micro-amplitude, completely shaking off the electrophoretic paint from the workpiece surface. This ensures that no electrophoretic paint drips during subsequent suspension and transport, avoiding material waste and environmental pollution.

Description

Technical Field

[0001] This application relates to the field of electrophoretic coating equipment technology, and in particular to a workpiece suspension anti-drip bracket. Background Technology

[0002] Electrophoretic coating is a coating technology that uses an electric field to directionally deposit paint particles onto the surface of a conductive workpiece. It is characterized by high efficiency, environmental friendliness, and uniform coating, and is widely used in the automotive and metal processing industries. The core of electrophoretic coating is to use an external electric field to cause charged particles (resin, pigment) in the electrophoretic paint (water-soluble coating) to migrate and deposit onto the oppositely charged workpiece surface, forming a dense coating. In wet coating processes such as electrophoretic coating, powder coating, and dipping, the material waste and environmental pollution caused by paint dripping after the workpiece exits the coating tank have long plagued the industry.

[0003] When the workpiece is removed from the electrophoretic pool, a large amount of electrophoretic paint will be carried out from the surface of both the workpiece and the support. Most of this electrophoretic paint will fall back into the electrophoretic pool due to gravity, while the remaining part of the electrophoretic paint will fall from the surface of the workpiece to the ground during the suspension and transportation of the workpiece, resulting in material waste and environmental pollution. Therefore, improvements have been made to the anti-drip support for the workpiece suspension. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a workpiece suspension anti-drip bracket, which overcomes the shortcomings of the prior art and aims to solve the problem that electrophoretic paint liquid will fall from the surface of the workpiece onto the ground during the suspension and transportation of the workpiece, causing material waste and environmental pollution.

[0005] To achieve the above objectives, this application provides the following technical solution: a workpiece suspension anti-drip bracket, including an electric pool, a guide rail above the electric pool, a railcar slidably connected to the outside of the guide rail, an electric telescopic rod fixedly connected to the bottom of the railcar, a connecting block fixedly connected to the telescopic end of the electric telescopic rod, a workpiece hanger for placing workpieces fixedly connected to the bottom of the connecting block by a hook, an installation plate fixedly installed on one side of the upper surface of the electric pool, a positioning frame fixedly installed on the inner wall of the installation plate outside the connecting block, a rotating shaft rotatably connected inside the positioning frame, a motor for driving the rotating shaft to rotate fixedly installed on the side wall of the positioning frame, a rotating ring fixedly sleeved at the center of the outer surface of the rotating shaft, a movable groove opened at the bottom of the rotating ring, and an impact block rotatably connected inside the movable groove.

[0006] By adopting the above technical solution, the railcar moves along the guide rail to achieve horizontal transport of the workpiece. When the railcar moves directly above the electrophoretic coating pool, the electric telescopic rod controls the connecting block to move downward, causing the workpiece hanger to descend vertically and immerse itself in the electrophoretic coating pool, thereby achieving electrophoretic coating of the workpiece. After the electrophoretic coating of the workpiece is completed, the electric telescopic rod drives the workpiece hanger to rise vertically and leave the electrophoretic coating pool. The motor drives the rotating shaft to rotate, causing the rotating ring to rotate, so that the impact block periodically impacts the connecting block, transmitting the vibration force to the workpiece hanger to generate high-frequency micro-amplitude vibration, which can completely shake off the electrophoretic paint on the surface of the workpiece, ensuring that no electrophoretic paint drips during the subsequent suspension and transportation process, avoiding material waste and environmental pollution.

[0007] As a preferred technical solution of this application, the track vehicle is parked directly above the electric pool, and its position is perpendicularly aligned with the central axis of the electric pool. The positioning frame, rotating shaft, rotating ring and impact block are all symmetrically distributed along the central axis of the electric pool.

[0008] By adopting the above technical solution, when the railcar is parked directly above the electric pool, the impact block can periodically impact the connecting block under the drive of the motor.

[0009] As a preferred technical solution of this application, buffer pads are fixedly connected to both outer walls of the impact block, and the buffer pads are rubber components.

[0010] By adopting the above technical solution and setting a buffer pad, the impact block will not cause damage to the outer surface of the connecting block when it impacts it.

[0011] As a preferred technical solution of this application, a fan is embedded and installed inside the mounting plate on the outside of the workpiece hanger.

[0012] By adopting the above technical solution, the electrophoretic paint on the workpiece hanger and the outer surface of the workpiece is blown off by a fan, which further accelerates the speed at which the electrophoretic paint falls off.

[0013] As a preferred technical solution of this application, the workpiece hanger includes a bracket, two hanging ears are symmetrically connected to the top of the bracket, the bracket is slidably sleeved on the hook through the hanging ears, and several rectangular grooves are opened at the bottom of the bracket. A crossbar is fixedly connected inside the rectangular groove, and a hook is rotatably sleeved on the outer surface of the crossbar.

[0014] By adopting the above technical solution, the hanging ears are symmetrically arranged and slidably connected with the hook to form a constraint, so that the vibration force can be transmitted from the connecting block to the workpiece hanger. The hook rotates and is connected to the crossbar, allowing the workpiece to swing freely during vibration, avoiding the paint liquid from being stuck due to surface tension and improving the dripping efficiency.

[0015] As a preferred technical solution of this application, the hook includes a hook body that is rotatably sleeved on the outer surface of the crossbar, a locking block is rotatably connected to the side wall of the hook body, and a return spring is fixedly connected between the locking block and the hook body.

[0016] By adopting the above technical solution, a locking and fixing structure is formed through the cooperation between the hook body, the locking block and the return spring, ensuring that the workpiece will not fall off the hook due to vibration.

[0017] As a preferred technical solution of this application, the connecting block, hook and workpiece hanger are all aluminum alloy components.

[0018] By adopting the above technical solutions, the aluminum alloy components have a low density, which significantly reduces the total weight of the suspension system. The aluminum alloy components are also prone to forming a dense oxide film on their surface, which effectively resists the corrosion of chemical solvents in the electrophoretic paint and extends the service life of the components.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, the railcar moves along the guide rail to achieve horizontal transport of the workpiece. When the railcar moves directly above the electrophoretic coating pool, the electric telescopic rod controls the connecting block to move downward, causing the workpiece hanger to descend vertically and immerse itself in the electrophoretic coating pool, thereby achieving electrophoretic coating of the workpiece. After the electrophoretic coating of the workpiece is completed, the electric telescopic rod drives the workpiece hanger to rise vertically and leave the electrophoretic coating pool. The motor drives the rotating shaft to rotate, causing the rotating ring to rotate, so that the impact block periodically impacts the connecting block, transmitting the vibration force to the workpiece hanger to generate high-frequency micro-amplitude vibration, which can completely shake off the electrophoretic paint on the surface of the workpiece, ensuring that no electrophoretic paint drips during subsequent suspension and transportation, avoiding material waste and environmental pollution.

[0020] 2. In this utility model, the hanging ears are symmetrically arranged and slidably connected with the hook to form a constraint, so that the vibration force can be transmitted from the connecting block to the workpiece hanger. The hook is rotated and connected to the crossbar, allowing the workpiece to swing freely during vibration, avoiding the paint liquid from stagnating due to surface tension, and improving the dripping efficiency. The locking and fixing structure is formed by the cooperation between the hook body, the locking block and the return spring to ensure that the workpiece will not fall off the hook due to vibration.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 - Figure 5As shown, the workpiece suspension anti-drip bracket provided in this embodiment includes an electric pool 1, a guide rail 2 above the electric pool 1, a track trolley 3 slidably connected to the outside of the guide rail 2, an electric telescopic rod 4 fixedly connected to the bottom of the track trolley 3, a connecting block 5 fixedly connected to the telescopic end of the electric telescopic rod 4, and a workpiece hanger 7 for placing workpieces fixedly connected to the bottom of the connecting block 5 by a hook 6. An installation plate 8 is fixedly installed on one side of the upper surface of the electric pool 1, and a positioning frame 10 is fixedly installed on the inner wall of the installation plate 8 outside the connecting block 5. A rotating shaft 11 is rotatably connected inside the positioning frame 10, and a motor 12 for driving the rotating shaft 11 is fixedly installed on the side wall of the positioning frame 10. A rotating ring 13 is fixedly sleeved at the center of the outer surface of the rotating shaft 11, and a movable groove 14 is opened at the bottom of the rotating ring 13. The inside of the tank 14 is rotatably connected to an impact block 15. During use, the railcar 3 moves along the guide rail 2 to achieve horizontal transport of the workpiece. When the railcar 3 moves directly above the electrophoretic pool 1, the electric telescopic rod 4 controls the connecting block 5 to move downward, causing the workpiece hanger 7 to descend vertically and immerse itself in the electrophoretic pool 1, thereby achieving electrophoretic coating of the workpiece. After the electrophoretic coating of the workpiece is completed, the electric telescopic rod 4 drives the workpiece hanger 7 to rise vertically and leave the electrophoretic pool 1. The motor 12 drives the rotating shaft 11 to rotate, causing the rotating ring 13 to rotate, so that the impact block 15 periodically impacts the connecting block 5, transmitting the vibration force to the workpiece hanger 7 to produce high-frequency micro-vibration, which can completely shake off the electrophoretic paint on the surface of the workpiece, ensuring that no electrophoretic paint drips during subsequent suspension transport, avoiding material waste and environmental pollution.

[0026] In this embodiment, as Figure 1-3 As shown, the track car 3 is parked directly above the electric pool 1, and its position is vertically aligned with the central axis of the electric pool 1. The positioning frame 10, rotating shaft 11, rotating ring 13 and impact block 15 are all symmetrically distributed along the central axis of the electric pool 1. When in use, when the track car 3 is parked directly above the electric pool 1, the impact block 15 can periodically impact the connecting block 5 under the drive of the motor 12.

[0027] In this embodiment, as Figure 3 As shown, buffer pads 16 are fixedly connected to both outer walls of the impact block 15. The buffer pads 16 are rubber components. In use, by setting the buffer pads 16, the impact block 15 will not cause damage to its outer surface when it impacts the connecting block 5.

[0028] In this embodiment, as Figure 1 As shown, a fan 9 is embedded inside the mounting plate 8 on the outside of the workpiece hanger 7. When in use, the fan 9 blows off the electrophoretic paint on the workpiece hanger 7 and the outer surface of the workpiece, further accelerating the speed at which the electrophoretic paint falls off.

[0029] In this embodiment, as Figure 2 and4 As shown, the workpiece hanger 7 includes a support 71. Two hanging ears 72 are symmetrically connected to the top of the support 71. The support 71 is slidably sleeved on the hook 6 through the hanging ears 72. Several rectangular grooves 73 are opened at the bottom of the support 71. A crossbar 74 is fixedly connected inside the rectangular grooves 73. A hook 75 is rotatably sleeved on the outer surface of the crossbar 74. In use, the hanging ears 72 are symmetrically arranged and slidably sleeved on the hook 6 to form a constraint, so that the vibration force can be transmitted from the connecting block 5 to the workpiece hanger 7. The hook 75 is rotatably sleeved on the crossbar 74, allowing the workpiece to swing freely during vibration, avoiding the paint liquid from stagnating due to surface tension and improving the dripping efficiency.

[0030] In this embodiment, as Figure 4 and 5 As shown, the hook 75 includes a hook body 751 that is rotatably sleeved on the outer surface of the crossbar 74. A locking block 752 is rotatably connected to the side wall of the hook body 751, and a return spring 753 is fixedly connected between the locking block 752 and the hook body 751. In use, the hook body 751, the locking block 752 and the return spring 753 cooperate to form a locking and fixing structure, ensuring that the workpiece will not fall off the hook 75 due to vibration.

[0031] In this embodiment, as Figure 1 As shown, the connecting block 5, hook 6 and workpiece bracket 7 are all aluminum alloy components. When in use, the low density of aluminum alloy components significantly reduces the total weight of the suspension system. The surface of the aluminum alloy components is easy to form a dense oxide film, which effectively resists the corrosion of chemical solvents in the electrophoretic paint and extends the service life of the components.

[0032] The working principle of this utility model is as follows: When using the workpiece suspension anti-drip bracket of this application, first hang the workpiece hanger 7 full of workpieces on the hook, then start the railcar 3. The railcar 3 moves along the guide rail 2 to realize the horizontal transportation of the workpiece. When the railcar 3 moves directly above the electrophoretic pool 1, the electric telescopic rod 4 controls the connecting block 5 to move downward, so that the workpiece hanger 7 descends vertically and is immersed in the electrophoretic pool 1, thereby realizing the electrophoretic coating of the workpiece. After the electrophoretic coating of the workpiece is completed, the electric telescopic rod 4 drives the workpiece hanger 7 to rise vertically and leave the electrophoretic pool 1. The motor 12 drives the rotating shaft 11 to rotate, which drives the rotating ring 13 to rotate, so that the impact block 15 periodically impacts the connecting block 5, transmitting the vibration force to the workpiece hanger 7 to generate high-frequency micro-vibration, which can completely shake off the electrophoretic paint on the surface of the workpiece. During this process, the fan 9 blows air towards the workpiece hanger 7 to blow off the electrophoretic paint on the workpiece hanger 7 and the outer surface of the workpiece, further accelerating the falling speed of the electrophoretic paint.
