Description

Technical Field

[0001] The invention relates to the technical field of electrophoresis bubble elimination equipment, and in particular to an electrophoresis hanger and an electrophoresis bubble elimination device. Background Art

[0002] At present, many workpieces are coated with paint by electrophoresis, which adheres the paint to the surface of the workpiece to form a paint film.

[0003] For inner cavity workpieces, bubbles will appear on the top of the inner cavity of the workpiece during the electrophoresis process. These bubbles will block the electrophoretic coating, causing the coating to be unable to contact the workpiece surface, thereby causing the bottom of the workpiece to be exposed. The exposed bottom requires manual repainting, which is costly and easily pollutes the environment. Summary of the invention

[0004] The object of the present invention is to provide an electrophoresis hanger and an electrophoresis bubble elimination device to alleviate the technical problem of the electrophoresis painting of inner cavity workpieces in the prior art that the bottom of the workpiece is easily exposed.

[0005] The electrophoresis hanger provided by the invention comprises a hanger body, a hanging piece and a hook.

[0006] Wherein, the hanging member is connected to the hanger body, and the hook is rotatably matched with the hanger body.

[0007] The hanging member has a hook portion, and both the hook portion and the hook are used to hook the workpiece. The hook can be detached from the workpiece by rotation, and the workpiece can be turned downward around the hook portion after being detached from the hook.

[0008] Preferably, as an implementable embodiment, the hook is higher than the hook portion.

[0009] Preferably, as an implementable embodiment, the hook and the hook portion are used to hook the upper and lower ends of the workpiece respectively.

[0010] Preferably, as an implementable embodiment, the hook portion is in an arc shape, and the central angle corresponding to the hook portion is 70°-80°.

[0011] Preferably, as an implementable embodiment, the hook portion is used to hook the through hole on the workpiece, and there is a gap between the hook portion and the through hole on the workpiece.

[0012] Preferably, as an implementable embodiment, the material of the suspension member is conductive metal.

[0013] Preferably, as an implementable embodiment, there are two hanging members, and the two hanging members are respectively used to hook the two opposite sides of the workpiece in the transverse direction.

[0014] Preferably, as an implementable embodiment, the hanging member is hooked on the hanger body.

[0015] Preferably, as an implementable embodiment, the electrophoresis hanger also includes a lever, the lever having a connecting section, an active section and a driven section, the connecting section rotatably cooperates with the hanger body, the active section is fixedly connected above the connecting section, the driven section is fixedly connected below the connecting section, and the driven section can push the hook to rotate from the inner side of the hook.

[0016] Correspondingly, the present invention provides an electrophoresis bubble elimination device, comprising a driving mechanism and the electrophoresis hanger, wherein the driving mechanism is used to drive the hanger to rotate.

[0017] Preferably, as an implementable embodiment, the driving mechanism is fixedly arranged relative to the electrophoresis tank.

[0018] Preferably, as an implementable embodiment, the driving mechanism includes a motor and a transmission rod, the rotating shaft of the motor is transmission-connected to the transmission rod, the transmission rod and the rotating shaft are arranged at an angle, and the transmission rod can drive the lever of the electrophoresis hanger to rotate.

[0019] Preferably, as an implementable embodiment, the rotating shaft of the motor is arranged vertically, and the transmission rod is arranged horizontally.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] The electrophoresis hanger provided by the present invention is mainly composed of a hanger body, a hanging member and a hook, wherein the hanging member is provided with a hook portion, the hanging member is connected to the hanger body, and the hook is rotatably matched with the hanger body.

[0022] When the workpiece needs to be electrophoretically painted, the workpiece is first hooked with the hook portion and the hook of the suspension member at the same time, so that the workpiece is suspended on the electrophoretic hanger and the workpiece is immersed in the electrophoretic paint. At this time, electrophoretic bubbles will appear at the top of the inner cavity of the workpiece (referring to the top of the workpiece in the current state, not the top of the workpiece in the use state), and these electrophoretic bubbles will block the electrophoretic paint; after the workpiece is electrophoresed in the electrophoretic liquid for a period of time (the duration of this period of time is not shorter than the duration of electrophoretic painting of the position of the workpiece not covered by the electrophoretic bubbles), the hook is driven to rotate so that the hook is separated from the workpiece. At this time, the workpiece that has lost the hook positioning will lose balance and flip downward around the hook portion of the suspension member under the action of its own gravity, and the electrophoretic bubbles will not rotate with the inner cavity of the workpiece; in the process of flipping the workpiece, the electrophoretic bubbles will move along the surface of the inner cavity, so that the position on the surface of the inner cavity of the workpiece originally covered by the electrophoretic bubbles can contact with the electrophoretic paint, thereby alleviating the problem of the bottom of the workpiece being exposed, and then, the cost of manual paint touch-up can be reduced, and the pollution to the environment can be reduced.

[0023] It should be noted that, since the workpiece can be turned downward around the suspension member under the action of its own gravity by simply detaching the hook from the workpiece, not much driving energy will be consumed, which is conducive to reducing energy consumption.

[0024] The electrophoresis bubble elimination device of the present invention comprises a driving mechanism and the electrophoresis hanger, and the driving mechanism can drive the hanger to rotate.

[0025] Therefore, the electrophoretic bubble elimination device provided by the present invention not only has all the advantages of the above-mentioned electrophoretic hanger, but also can alleviate the problem of the bottom of the workpiece being exposed, reduce the cost of manual paint touch-up, and reduce pollution to the environment, and the electrophoresis quality of the workpiece is relatively high; in addition, the electrophoretic bubble elimination device provided by the present invention utilizes a driving device to drive the hook to rotate, which not only improves the degree of mechanization and saves manpower, but also reduces the risk of electric shock to workers because there is no need to manually drive the hook to rotate.

[0040] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0044] See also Figure 1 - Figure 4 The electrophoresis hanger 100 provided in this embodiment is mainly composed of a hanger body 110, a hanging member 120 and a hook 130, wherein the hanging member 120 has a hook portion 121, the hanging member 120 is connected to the hanger body 110, and the hook 130 is rotatably matched with the hanger body 110.

[0045] Continue to see Figure 5 When the workpiece 200 needs to be electrophoretically painted, the hook 121 of the hanging member 120 and the hook 130 are first used to hook the workpiece 200 at the same time, so that the workpiece 200 is suspended on the electrophoretic hanger 100, and the workpiece 200 is immersed in the electrophoretic paint. At this time, electrophoretic bubbles 400 will appear at the top of the inner cavity of the workpiece 200 (referring to the top of the workpiece 200 in the current state, not the top of the workpiece 200 in the use state), and these electrophoretic bubbles 400 will block the electrophoretic paint; after the workpiece 200 is electrophoresed in the electrophoretic liquid for a period of time (the length of this period of time is not shorter than the length of time for the workpiece 200 to complete the electrophoretic painting at the position not covered by the electrophoretic bubbles 400), the hook 130 is driven to rotate so that the hook 130 is separated from the workpiece 200. At this time, the workpiece 200 that loses the positioning of the hook 130 will lose balance and flip downward around the hook 121 of the hanging member 120 under the action of its own gravity, and the electrophoretic bubbles 400 will not rotate with the inner cavity of the workpiece 200; continue to refer to Figure 6 During the flipping process of the workpiece 200, the electrophoretic bubbles 400 will move along the inner cavity surface, so that the position on the inner cavity surface of the workpiece 200 originally covered by the electrophoretic bubbles 400 can contact with the electrophoretic coating, thereby alleviating the problem of the bottom of the workpiece 200 being exposed, and further, reducing the cost of manual touch-up and reducing pollution to the environment.

[0046] It should be noted that, since the workpiece 200 can be turned downward around the suspension member 120 under the action of its own gravity by simply detaching the hook 130 from the workpiece 200, not much driving energy will be consumed, thereby reducing energy consumption.

[0047] Preferably, the height of the hook 130 is set to be higher than the hook portion 121 of the suspension member 120, so that when the hook 130 is detached from the workpiece 200, the workpiece 200 will flip at a larger angle to reduce the area of ​​the portion that has been covered by the electrophoretic bubbles 400, and even all the electrophoretic bubbles 400 can be detached from the position originally covered by the electrophoretic bubbles 400, further alleviating the problem of the bottom of the workpiece 200 being exposed.

[0048] For further information, see Figure 1 - Figure 7 The hook 130 and the hook portion 121 of the hanging member 120 can be hooked onto the upper and lower ends of the workpiece 200 respectively. In this way, when the hook 130 is separated from the workpiece 200, the workpiece 200 will flip about 180°, and the position of the inner cavity of the workpiece 200, which was originally at the top, will rotate to the bottom, and the electrophoretic bubbles 400 will cover the surface of the inner cavity of the workpiece 200 which is at the top at this time (that is, the surface of the inner cavity of the workpiece 200 which was originally at the bottom). In this way, all the electrophoretic bubbles 400 can be separated from the positions originally covered by the electrophoretic bubbles 400, and the workpiece 200 will basically not have the problem of bottom exposure.

[0049] Preferably, the hook portion 121 can be hooked on the through hole on the workpiece 200 to achieve the connection between the hook portion 121 and the workpiece 200, and a gap is provided between the hook portion 121 and the through hole on the workpiece 200. Thus, during the flipping process of the workpiece 200, the portion of the suspension member 120 that contacts the workpiece 200 will generate friction with the workpiece 200. Thus, the workpiece 200 can cut the paint film attached to the contact point between the hook portion 121 of the suspension member 120 and the workpiece 200. That is to say, under the cutting action of the workpiece 200, the paint film at the contact point between the hook portion 121 of the suspension member 120 and the workpiece 200 will become thinner or disappear, thereby reducing the resistance between the suspension member 120 and the workpiece 200, so that a sufficiently thick paint film can be attached to the surface of the workpiece 200, thereby improving the electrophoresis quality of the workpiece 200.

[0050] In particular, the hook portion 121 may be configured to be in an arc shape, and the central angle of the hook portion 121 may be configured to be 70°-80°, thereby reducing the possibility of the workpiece 200 being separated from the hook portion 121 and improving the reliability of the electrophoresis rack 100 .

[0051] It should be noted that the shape of the hook portion 121 of the electrophoresis hanger 100 provided in this embodiment is not necessarily an arc shape, and can also be set to other shapes as long as it can ensure that the workpiece 200 will not fall off the hook portion 121 when rotating.

[0052] Specifically, the suspension member 120 may be made of conductive metal, which can not only ensure the conductive function of the suspension member 120 , but also ensure the strength of the suspension member 120 , thereby extending the service life of the suspension member 120 .

[0053] Preferably, two suspension members 120 can be provided, and the two suspension members 120 can respectively hook the two opposite sides of the workpiece 200 in the transverse direction, so that the forces on the electrophoresis hanger 100 and the workpiece 200 can be more balanced, thereby facilitating the maintenance of the stability of the electrophoresis hanger 100 and the workpiece 200.

[0054] Furthermore, the two suspension members 120 are symmetrically arranged relative to the hook 130. When the hook portion 121 of the suspension member 120 and the hook 130 hook the workpiece 200 at the same time, it is convenient to maintain the stability of the workpiece 200, reduce the possibility of the workpiece 200 being skewed, and can reduce the force between the hook 130 and the workpiece 200, thereby extending the service life of the hook 130.

[0055] When the workpiece 200 is flipped, the force is unbalanced, which will give the hook 121 of the suspension member 120 a force toward the side away from the workpiece 200. Therefore, the suspension member 120 can be hooked on the hanger body 110. As a result, the hook 121 of the suspension member 120 can rotate around the part where it is hooked on the hanger body 110 after receiving the force, which can reduce the shaking amplitude of the hanger body 110.

[0056] In the specific structure of the electrophoresis hanger 100, a lever 140 can also be provided. The lever 140 has a connecting section 141, an active section 142 and a driven section 143. The connecting section 141 is rotatably matched with the hanger body 110. The active section 142 is fixedly connected to the upper part of the connecting section 141, and the driven section 143 is fixedly connected to the lower part of the connecting section 141. In this way, the active section 142 of the lever 140 is pushed to rotate around the connecting section 141, so that the driven section 143 can also rotate around the connecting section 141. Furthermore, the driven section 143 can be used to push the hook 130 to rotate from the inner side (i.e., the bending direction of the hook 130) of the hook 130, so that the hook 130 can be separated from the workpiece 200.

[0057] The electrophoresis bubble elimination device of this embodiment includes a driving mechanism 300 and the electrophoresis hanger 100 . The driving mechanism 300 can drive the hanger 130 to rotate.

[0058] Therefore, the electrophoretic bubble elimination device provided in this embodiment not only has all the advantages of the above-mentioned electrophoretic hanger 100, but also can alleviate the problem of the bottom of the workpiece 200 being exposed, reduce the cost of manual paint touch-up, and reduce pollution to the environment, and the electrophoresis quality of the workpiece 200 is relatively high; in addition, the electrophoretic bubble elimination device provided in this embodiment uses a driving device to drive the hook 130 to rotate, which not only improves the degree of mechanization and saves manpower, but also reduces the risk of electric shock to workers because there is no need to manually drive the hook 130 to rotate.

[0059] The driving mechanism 300 can be fixedly arranged relative to the electrophoresis tank, and the electrophoresis hanger 100 with the workpiece 200 suspended thereon passes through the position that the driving mechanism 300 can drive in sequence, so that the driving mechanism 300 can drive the hooks 130 on the electrophoresis hanger 100 to move to their working positions in sequence. Compared with the structure in which one driving mechanism 300 is installed for one electrophoresis hanger 100, this embodiment adopts a structure in which one driving mechanism 300 cyclically drives the hooks 130 of multiple electrophoresis hangers 100, which not only saves the cost of the driving mechanism 300, but also saves the extra energy required for the electrophoresis hanger 100 to drive the driving mechanism 300 to move.

[0060] On the basis that the lever 140 for driving the hook 130 to rotate is provided in the specific structure of the electrophoresis hanger 100, a motor 310 and a transmission rod 320 can be provided in the specific structure of the driving mechanism 300. The rotation of the motor 310 is connected to the transmission rod 320, and the transmission rod 320 is arranged at an angle with the rotating shaft. Therefore, when the motor 310 drives the transmission rod 320 to rotate, any position on the transmission rod 320 can rotate around the central axis of the rotating shaft, and each time the transmission rod 320 rotates one circle, a certain section of the transmission rod 320 will pass through a specific area. When the electrophoresis hanger 100 with the workpiece 200 suspended thereon moves, the hook 130 on the electrophoresis hanger 100 can reach the above-mentioned specific area, so that the rotating transmission rod 320 can drive the lever 140 to rotate, and then, the lever 140 is used to drive the hook 130 to rotate, so that the hook 130 and the workpiece 200 are separated from each other.

[0061] Generally, the electrophoresis hanger 100 with the workpiece 200 suspended thereon will be moved from one end of the electrophoresis tank to the other end in sequence with a small spacing. Therefore, during the electrophoresis of batch workpieces 200, the motor 310 can work continuously for a long time after being turned on, without frequent starting and stopping, thereby extending the service life of the motor 310.

[0062] In fact, when the transmission rod 320 rotates, it will hit and push the active section 142 of the lever 140 to rotate. The rotation of the active section 142 of the lever 140 can drive the driven section 143 to rotate, and then the driven section 143 can push the hook 130 to rotate.

[0063] On this basis, hooking the hanging member 120 on the hanger body 110 can alleviate the swing amplitude of the hanger body 110, thereby reducing the probability that the hanger body 110 swings too much and interferes with the normal rotation of the transmission rod 320.

[0064] Furthermore, the rotating shaft of the motor 310 can be set vertically and the transmission rod 320 can be set horizontally, so that when the motor 310 is running, the transmission shaft can rotate in a horizontal plane, which can further reduce the probability of the hanger body 110 interfering with the normal rotation of the transmission rod 320, and is more convenient for structural design and has a better driving effect.

[0065] In summary, the present invention discloses an electrophoresis hanger 100 and an electrophoresis bubble elimination device, which overcomes many technical defects of conventional electrophoresis painting of inner cavity type workpieces 200. The electrophoresis hanger 100 and the electrophoresis bubble elimination device provided in this embodiment can alleviate the problem of the bottom of the workpiece 200 being exposed, reduce the cost of manual touch-up, and reduce pollution to the environment, and the electrophoresis quality of the workpiece 200 is higher; in addition, the degree of mechanization is higher, which can save manpower, and because there is no need to manually drive the hook 130 to rotate, it can also reduce the risk of electric shock to workers.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
