[0060] The present invention will be further described below in conjunction with the accompanying drawings.

[0061] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. When the surface temperature of the heat exchanger is 10 - 15 °C lower than the air temperature, it will cause the generation of condensate water, resulting in corrosion. To prevent the condensation phenomenon, usually a layer of heat insulation cotton is manually wrapped on the surface of the heat exchanger and the pipeline to play a heat insulation role; however, due to the variety and complex structure of the heat exchangers, this method has the problems of cumbersome operation, high labor intensity and low efficiency. Therefore, it is proposed to dip-coat a heat insulation coating on the surface of the heat exchanger to replace the wrapping of the sponge for heat insulation. However, currently, the method of manually dip-coating the heat exchanger is generally adopted, which has the problems of high labor intensity, low production efficiency, and cannot guarantee the quality of the workpiece.

[0062] Embodiment 1

[0063] As Figure 1 、 Figure 2As shown in the figure, to solve the above technical problems, an embodiment of the present invention provides a dip coating device, which includes a frame 10, a paint bucket assembly 20, a hanger assembly 30, and a transfer assembly 40; the frame 10 includes a loading section 110 and an unloading section 120; the paint bucket assembly 20 is arranged between the loading section 110 and the unloading section 120, and the paint bucket assembly 20 contains paint; the hanger assembly 30 is configured to be able to hang the workpiece 70 to be dip coated; the transfer assembly 40 includes a driving part 410 and a hanging part 420 arranged on the driving part 410; wherein, the hanger assembly 30 is configured to be able to be respectively hung on the loading section 110, the unloading section 120, and the hanging part 420, and the driving part 410 is configured to be able to drive the hanging part 420 to reciprocate between the loading section 110, the paint bucket assembly 20, and the unloading section 120, and drive the hanging part 420 to enter and exit the paint bucket assembly 20, so as to pick up and place the hanger assembly 30, and perform loading, unloading, and dip coating on the workpiece 70 to be dip coated.

[0064] As can be seen from the above, the driving part 410 drives the hanging part 420 to reciprocate between the loading section 110, the paint bucket assembly 20, and the unloading section 120, so as to pick up the hanger assembly 30, and transfer the hanger assembly 30 and the workpiece 70 to be dip coated suspended thereon, realizing the loading and unloading of the workpiece 70 to be dip coated; specifically, the driving part 410 drives the hanging part 420 to move to the loading section 110, pick up the hanger assembly 30 of the loading section 110, and drive the hanger assembly 30 and the workpiece 70 to be dip coated suspended thereon to move to the paint bucket assembly 20, realizing the loading of the workpiece 70 to be dip coated; the driving part 410 drives the hanging part 420 to move to the unloading section 120, and the unloading section 120 picks up the hanger assembly 30 of the hanging part 420, realizing the unloading of the workpiece 70 to be dip coated. By driving the hanging part 420 to enter and exit the paint bucket assembly 20 by the driving part 410, the workpiece 70 to be dip coated on the hanging part 420 is immersed in the paint for coating, thus realizing dip coating. Therefore, the present invention can automatically realize loading, unloading, and dip coating, greatly reducing the manual handling of the workpiece 70 to be dip coated, thereby effectively reducing the labor intensity, improving the production efficiency, and being able to control the movement path of the workpiece 70 to be dip coated, preventing bumps during the dip coating process, and ensuring the stable quality of the workpiece 70 to be dip coated.

[0065] It should be noted that the workpiece 70 to be dip coated includes, but is not limited to, a plate heat exchanger. A plate heat exchanger is a heat exchange device composed of a series of metal sheets with a certain corrugated shape. One side of the plate heat exchanger is provided with a connection joint and a heat exchange tube connected to the connection joint; in addition, before dip coating, the connection joint without the connected heat exchange tube and the tube head of the heat exchange tube far from the connection joint are wrapped with rubber caps to prevent the paint from entering.

[0066] It should also be noted that the coating material in the material bucket assembly 20 can be a heat-insulating coating. For example, the heat-insulating coating is a heat-insulating coating of ceramic microbeads, which has the characteristics of being hollow, light in weight, and low in thermal conductivity. It can not only block heat but also improve the heat-insulating performance of the coating film, and at the same time achieve the composite effect of emitting sunlight and blocking heat.

[0067] It should also be noted that the feeding part 110, the material bucket assembly 20, and the discharging part 120 are arranged at intervals in the first direction.

[0068] It should also be noted that a non-stick coating can be provided on the surface of the fixture assembly 30, so that it is convenient to clean the fixture assembly 30 after it is adhered with the coating material.

[0069] Embodiment 2

[0070] As Figure 1 、 Figure 2 shown, the dip coating device includes a frame 10, a material bucket assembly 20, a fixture assembly 30, and a transfer assembly 40; the frame 10 includes a feeding part 110 and a discharging part 120; the material bucket assembly 20 is arranged between the feeding part 110 and the discharging part 120, and the material bucket assembly 20 contains coating material; the fixture assembly 30 is configured to be able to hang the workpiece 70 to be dip-coated; the transfer assembly 40 includes a driving part 410 and a hanging part 420 arranged on the driving part 410; wherein, the fixture assembly 30 is configured to be able to be respectively hung on the feeding part 110, the discharging part 120, and the hanging part 420, and the driving part 410 is configured to be able to drive the hanging part 420 to reciprocate between the feeding part 110, the material bucket assembly 20, and the discharging part 120, and drive the hanging part 420 to enter and exit the material bucket assembly 20 to pick up and place the fixture assembly 30, and perform feeding, discharging, and dip coating on the workpiece 70 to be dip-coated.

[0071] As can be seen from the above, the driving part 410 drives the hanging part 420 to reciprocate between the loading part 110, the material bucket assembly 20 and the unloading part 120, so as to pick up the hanging tool assembly 30 and transfer the hanging tool assembly 30 and the workpieces 70 to be dip-coated suspended thereon, realizing the loading and unloading of the workpieces 70 to be dip-coated. Specifically, the driving part 410 drives the hanging part 420 to move to the loading part 110, pick up the hanging tool assembly 30 of the loading part 110, and drive the hanging tool assembly 30 and the workpieces 70 to be dip-coated suspended thereon to move to the material bucket assembly 20, realizing the loading of the workpieces 70 to be dip-coated. The driving part 410 drives the hanging part 420 to move to the unloading part 120, and the unloading part 120 picks up the hanging tool assembly 30 of the hanging part 420, realizing the unloading of the workpieces 70 to be dip-coated. By driving the hanging part 420 to enter and exit the material bucket assembly 20 by the driving part 410, the workpieces 70 to be dip-coated on the hanging part 420 are immersed in the paint for coating, thereby realizing dip coating. Therefore, the present invention can automatically realize loading, unloading and dip coating, greatly reducing the manual handling of the workpieces 70 to be dip-coated, thereby effectively reducing the labor intensity, improving the production efficiency, and being able to control the movement path of the workpieces 70 to be dip-coated, preventing bumps during the dip coating process and ensuring the stable quality of the workpieces 70 to be dip-coated.

[0072] It should be noted that the workpieces 70 to be dip-coated include but are not limited to plate heat exchangers. A plate heat exchanger is a heat exchange device composed of a series of metal sheets with a certain corrugated shape. One side of the plate heat exchanger is provided with a connection joint and a heat exchange tube connected to the connection joint. In addition, before dip coating, the connection joint without the heat exchange tube connected and the tube head of the heat exchange tube far from the connection joint are both wrapped with rubber caps to prevent the paint from entering.

[0073] It should also be noted that the paint in the material bucket assembly 20 can be a heat-insulating paint. For example, the heat-insulating paint is a heat-insulating paint of the ceramic microsphere type, which has the characteristics of being hollow, light in weight and low in thermal conductivity. It can not only play the role of blocking heat, but also improve the heat-insulating performance of the coating film, and at the same time achieve the composite effect of emitting sunlight and blocking heat.

[0074] It should also be noted that the loading part 110, the material bucket assembly 20 and the unloading part 120 are arranged at intervals in the first direction.

[0075] It should also be noted that a non-stick coating can be provided on the surface of the hanging tool assembly 30, so as to facilitate the cleaning of the hanging tool assembly 30 after being adhered with the paint.

[0076] Such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 、 Figure 11As shown, in some embodiments, the fixture assembly 30 includes a hanging rack 310 and a support plate 320; one end of the support plate 320 is connected to the hanging rack 310, and the support plate 320 is configured to be detachably connected to the workpiece 70 to be dip-coated; wherein, a loading slot 1101, an unloading slot 1201, and a dip-coating slot 430 for inserting the hanging rack 310 are respectively provided on the loading section 110, the unloading section 120, and the hanging section 420.

[0077] By providing the hanging rack 310, the loading slot 1101, the unloading slot 1201, and the dip-coating slot 430, a structural basis is provided for the suspension of the fixture assembly 30. By using the detachable connection between the support plate 320 and the workpiece 70 to be dip-coated, the fixture assembly 30 can be reused during the painting process.

[0078] It should be noted that, as Figure 10 shown, the hanging rack 310 includes a hanging rod and a transition rod perpendicularly connected to the hanging rod, so that the hanging rack 310 is T-shaped, and a weight-reducing hole is provided on the transition rod. Among them, the hanging rod can be inserted into the loading slot 1101, the unloading slot 1201, and the dip-coating slot 430 to achieve suspension.

[0079] It should also be noted that, as Figure 2 、 Figure 3 shown, the loading section 110 includes a loading rack 1102. The loading slot 1101 includes a first through slot 1105 and a first limiting slot 1103 provided on the loading rack 1102. The first limiting slots 1103 are respectively located on both sides of the first through slot 1105, and first guiding inclined surfaces 1104 are respectively provided on the opposite inner walls of the first limiting slots 1103; a space is reserved through the first through slot 1105 for the hanging section 420 to pick up the fixture assembly 30, avoiding interference and preventing the hanging section 420 from smoothly picking up the fixture assembly 30. The first limiting slot 1103 plays a role in fixing and limiting the fixture assembly 30 to prevent the fixture assembly 30 from falling, and the first guiding inclined surface 1104 plays a guiding role during the process of inserting the hanging rack 310 into the first limiting slot 1103, facilitating the suspension of the hanging rack 310.

[0080] It should also be noted that, as Figure 2 、 Figure 4As shown in the figure, the blanking part 120 includes a blanking rack 1202. The blanking hanging groove 1201 includes a second through groove 1206 and a second limiting groove 1204 provided on the blanking rack 1202. The second limiting grooves 1204 are respectively located on both sides of the second through groove 1206, and second guiding inclined surfaces 1205 are respectively provided on the opposite inner walls of the second limiting grooves 1204. A space is reserved through the second through groove 1206 for the hanging part 420 to pick up the hanging tool assembly 30, avoiding interference and preventing the hanging part 420 from smoothly picking up the hanging tool assembly 30. The second limiting grooves 1204 play a role in fixing and limiting the hanging tool assembly 30 to prevent the hanging tool assembly 30 from falling, and the second guiding inclined surfaces 1205 play a guiding role during the process of inserting the hanging rack 310 into the second limiting grooves 1204 to facilitate the hanging of the hanging rack 310.

[0081] It should also be noted that, as Figure 2 shown in the figure, the blanking part 120 further includes a receiving tray 1203 provided on the blanking rack 1202. A receiving groove for receiving the coating material is provided on the receiving tray 1203, and a converging inclined surface is provided at the bottom of the receiving groove so that the coating materials dripping from the workpiece 70 to be dip-coated can quickly converge together, and the staff can recycle it.

[0082] As Figure 10 shown in the figure, in some embodiments, an avoidance groove 3201 is provided at one end of the support plate 320 away from the hanging rack 310, and a support hole for the fixing post 710 of the workpiece 70 to be dip-coated to pass through is provided on the support plate 320. Among them, the hanging tool assembly 30 further includes a fastening member 3203, and the fastening member 3203 is connected to the fixing post 710 so that the workpiece 70 to be dip-coated is fixed on the support plate 320.

[0083] By providing the avoidance groove 3201, an immersion coating position is reserved for the workpiece 70 to be dip-coated, so that all parts of the workpiece to be wetted can be immersed in the coating material and come into contact with the coating material, avoiding coating dead corners due to the blockage of the support plate 320 and preventing the workpiece 70 to be dip-coated from not being coated with the coating material at this part.

[0084] It should be noted that the fixing post 710 is located on the side of the plate heat exchanger away from the heat exchange tubes; the fastening member 3203 includes but is not limited to a disc-shaped nut, and the disc-shaped nut is threadedly connected to the fixing post 710, thereby fixing the workpiece 70 to be dip-coated on the support plate 320.

[0085] It should also be noted that, as Figure 10 shown in the figure, the support holes are respectively located on both sides of the avoidance groove 3201.

[0086] As Figure 11As shown, in some embodiments, the fixture assembly 30 further includes an air separation column 3204. The air separation column 3204 is sleeved outside the fixed column 710, and two ends of the air separation column 3204 are respectively abutted against the support plate 320 and the workpiece 70 to be dip-coated. Wherein, a plurality of air separation grooves 3205 are arranged at one end of the air separation column 3204 close to the workpiece 70 to be dip-coated, and the plurality of air separation grooves 3205 are arranged at intervals circumferentially around the air separation column 3204.

[0087] By providing the air separation column 3204, a gap is formed between the support plate 320 and the workpiece 70 to be dip-coated, and the contact area between the support plate 320 and the workpiece 70 to be dip-coated is reduced. This can not only prevent the paint from adhering the support plate 320 and the workpiece 70 to be dip-coated together, but also avoid the dip-coating dead angle caused by the shielding of the support plate 320, resulting in the situation that this part of the workpiece 70 to be dip-coated cannot be dip-coated with paint. By providing a plurality of air separation grooves 3205, the contact area between the support plate 320 and the workpiece 70 to be dip-coated is further reduced. At the same time, the paint can enter the inside of the air separation column 3204 through the air separation grooves 3205 to dip-coat the fixed column 710 and the surrounding area of the fixed column 710, thereby avoiding the dip-coating dead angle.

[0088] As Figure 2 、 Figure 5 As shown, in some embodiments, the driving part 410 includes a translation frame 4101, a first driving module 4102, a second driving module 4103 and a third driving module 4104. The translation frame 4101 is movably arranged on the frame 10. The first driving module 4102 is configured to drive the translation frame 4101 to move in a first direction. The second driving module 4103 is arranged on the translation frame 4101. The third driving module 4104 is movably arranged on the translation frame 4101, and the second driving module 4103 is configured to drive the third driving module 4104 to move in a second direction. Wherein, the hanging part 420 is arranged on the third driving module 4104, and the third driving module 4104 is configured to drive the hanging part 420 to move in a third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0089] The first driving module 4102, the second driving module 4103 and the third driving module 4104 drive the hanging part 420 to move in the first direction, the second direction and the third direction respectively, so that the hanging part 420 can move to a specified position for operation. Specifically, the first driving module 4102 is used to drive the hanging part 420 to move in the first direction, so that the hanging part 420 can reciprocate between the loading part 110, the material bucket assembly 20 and the unloading part 120; the second driving module 4103 and the third driving module 4104 are used to drive the hanging part 420 to move in the second direction and the third direction respectively, so that the hanging part 420 can be aligned with the loading part 110 and the unloading part 120; at the same time, the third driving module 4104 is used to drive the hanging part 420 to move in the third direction to adjust the height of the workpiece 70 to be dip-coated on the hanging part 420 immersed in the coating material.

[0090] It should be noted that the first driving module 4102 includes, but is not limited to, a gear-rack drive, a synchronous belt drive, a rolling screw, or a linear module structure;

[0098] As Figure 1 、 Figure 2As shown in the figure, the dip coating device includes a frame 10, a paint bucket assembly 20, a hanger assembly 30, and a transfer assembly 40; the frame 10 includes a loading section 110 and an unloading section 120; the paint bucket assembly 20 is arranged between the loading section 110 and the unloading section 120, and the paint bucket assembly 20 contains paint; the hanger assembly 30 is configured to be able to hang the workpiece 70 to be dip coated; the transfer assembly 40 includes a driving part 410 and a hanging part 420 arranged on the driving part 410; wherein, the hanger assembly 30 is configured to be able to be respectively hung on the loading section 110, the unloading section 120, and the hanging part 420, and the driving part 410 is configured to be able to drive the hanging part 420 to reciprocate between the loading section 110, the paint bucket assembly 20, and the unloading section 120, and drive the hanging part 420 to enter and exit the paint bucket assembly 20, so as to pick up and place the hanger assembly 30, and perform loading, unloading, and dip coating on the workpiece 70 to be dip coated.

[0099] As can be seen from the above, the driving part 410 drives the hanging part 420 to reciprocate between the loading section 110, the paint bucket assembly 20, and the unloading section 120, so as to pick up the hanger assembly 30, and transfer the hanger assembly 30 and the workpiece 70 to be dip coated suspended thereon, realizing the loading and unloading of the workpiece 70 to be dip coated; specifically, the driving part 410 drives the hanging part 420 to move to the loading section 110, pick up the hanger assembly 30 of the loading section 110, and drive the hanger assembly 30 and the workpiece 70 to be dip coated suspended thereon to move to the paint bucket assembly 20, realizing the loading of the workpiece 70 to be dip coated; the driving part 410 drives the hanging part 420 to move to the unloading section 120, and the unloading section 120 picks up the hanger assembly 30 of the hanging part 420, realizing the unloading of the workpiece 70 to be dip coated. By driving the driving part 410 to drive the hanging part 420 to enter and exit the paint bucket assembly 20, the workpiece 70 to be dip coated on the hanging part 420 is immersed in the paint for coating, thus realizing dip coating. Therefore, the present invention can automatically realize loading, unloading, and dip coating, greatly reducing the manual handling of the workpiece 70 to be dip coated, thereby effectively reducing the labor intensity, improving the production efficiency, and being able to control the movement path of the workpiece 70 to be dip coated, preventing bumps during the dip coating process, and ensuring the stable quality of the workpiece 70 to be dip coated.

[0100] It should be noted that the workpiece 70 to be dip coated includes but is not limited to a plate heat exchanger. A plate heat exchanger is a heat exchange device composed of a series of metal sheets with a certain corrugated shape. One side of the plate heat exchanger is provided with a connection joint and a heat exchange tube connected to the connection joint; in addition, before dip coating, the connection joint without the connected heat exchange tube and the tube head of the heat exchange tube far from the connection joint are both wrapped with rubber caps to prevent the paint from entering.

[0101] It should also be noted that the coating material in the material bucket assembly 20 can be a heat-insulating coating. For example, the heat-insulating coating is a heat-insulating coating of ceramic microbeads, which has the characteristics of being hollow, light in weight, and low in thermal conductivity. It can not only block heat but also improve the heat-insulating performance of the coating film, and at the same time achieve the composite effect of emitting sunlight and blocking heat.

[0102] It should also be noted that the feeding part 110, the material bucket assembly 20, and the discharging part 120 are arranged at intervals in the first direction.

[0103] It should also be noted that a non-stick coating can be provided on the surface of the fixture assembly 30, so as to facilitate the cleaning of the fixture assembly 30 after it is adhered with the coating material.

[0104] Such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 、 Figure 11 As shown, in some embodiments, the fixture assembly 30 includes a hanging rack 310 and a support plate 320; one end of the support plate 320 is connected to the hanging rack 310, and the support plate 320 is configured to be detachably connected to the workpiece 70 to be dip-coated; wherein, a feeding hanging groove 1101, a discharging hanging groove 1201, and a dip-coating hanging groove 430 for inserting the hanging rack 310 are respectively provided on the feeding part 110, the discharging part 120, and the hanging part 420.

[0105] By providing the hanging rack 310, the feeding hanging groove 1101, the discharging hanging groove 1201, and the dip-coating hanging groove 430, a structural basis is provided for the suspension of the fixture assembly 30. By using the detachable connection between the support plate 320 and the workpiece 70 to be dip-coated, the fixture assembly 30 can be reused during the coating process.

[0106] It should be noted that, as Figure 10 shown, the hanging rack 310 includes a hanging rod and a transition rod perpendicularly connected to the hanging rod, so that the hanging rack 310 is T-shaped, and a weight-reducing hole is provided on the transition rod. Among them, the hanging rod can be inserted into the feeding hanging groove 1101, the discharging hanging groove 1201, and the dip-coating hanging groove 430 to achieve suspension.

[0107] It should also be noted that, as Figure 2 、 Figure 3As shown in the figure, the loading section 110 includes a loading rack 1102. The loading hanging groove 1101 includes a first through groove 1105 and a first limiting groove 1103 provided on the loading rack 1102. The first limiting grooves 1103 are respectively located on both sides of the first through groove 1105, and first guiding inclined surfaces 1104 are respectively provided on the opposite inner walls of the first limiting grooves 1103. A space is reserved through the first through groove 1105 for the hanging portion 420 to pick up the hanging tool assembly 30, avoiding interference that may cause the hanging portion 420 to be unable to smoothly pick up the hanging tool assembly 30. The first limiting groove 1103 plays a role in fixing and limiting the hanging tool assembly 30 to prevent the hanging tool assembly 30 from falling, and the first guiding inclined surface 1104 plays a guiding role during the process of the hanging rack 310 being inserted into the first limiting groove 1103, facilitating the hanging of the hanging rack 310.

[0108] It should also be noted that, as Figure 2 , Figure 4 shown in the figure, the unloading section 120 includes an unloading rack 1202. The unloading hanging groove 1201 includes a second through groove 1206 and a second limiting groove 1204 provided on the unloading rack 1202. The second limiting grooves 1204 are respectively located on both sides of the second through groove 1206, and second guiding inclined surfaces 1205 are respectively provided on the opposite inner walls of the second limiting grooves 1204. A space is reserved through the second through groove 1206 for the hanging portion 420 to pick up the hanging tool assembly 30, avoiding interference that may cause the hanging portion 420 to be unable to smoothly pick up the hanging tool assembly 30. The second limiting groove 1204 plays a role in fixing and limiting the hanging tool assembly 30 to prevent the hanging tool assembly 30 from falling, and the second guiding inclined surface 1205 plays a guiding role during the process of the hanging rack 310 being inserted into the second limiting groove 1204, facilitating the hanging of the hanging rack 310.

[0109] It should also be noted that, as Figure 2 shown in the figure, the unloading section 120 further includes a receiving tray 1203 provided on the unloading rack 1202. A receiving groove for receiving the coating material is provided on the receiving tray 1203, and a converging inclined surface is provided at the bottom of the receiving groove so that the coating materials dripped from the workpiece 70 to be dip-coated can quickly converge together, and the staff can recycle it.

[0110] As Figure 10 shown in the figure, in some embodiments, an emptying groove 3201 is provided at one end of the support plate 320 away from the hanging rack 310, and a support hole for the fixing post 710 of the workpiece 70 to be dip-coated to pass through is provided on the support plate 320. Among them, the hanging tool assembly 30 further includes a fastener 3203, and the fastener 3203 is connected to the fixing post 710 so that the workpiece 70 to be dip-coated is fixed on the support plate 320.

[0111] By setting the clearance groove 3201, a dipping position is reserved for the workpiece 70 to be dip-coated, so that all parts of the workpiece to be wetted can be immersed in the coating and contact with the coating, avoiding dipping dead angles caused by the shielding of the support plate 320, resulting in the inability of this part of the workpiece 70 to be dip-coated with the coating.

[0112] It should be noted that the fixing post 710 is located on the side of the plate heat exchanger away from the heat exchange tubes; the fastener 3203 includes but is not limited to a disc nut, and the disc nut is threadedly connected to the fixing post 710, thereby fixing the workpiece 70 to be dip-coated on the support plate 320.

[0113] It should also be noted that as Figure 10 shown, the support holes are respectively located on both sides of the clearance groove 3201.

[0114] As Figure 11 shown, in some embodiments, the hanging tool assembly 30 further includes a spacer post 3204. The spacer post 3204 is sleeved outside the fixing post 710, and both ends of the spacer post 3204 are respectively abutted against the support plate 320 and the workpiece 70 to be dip-coated; wherein, a plurality of spacer grooves 3205 are provided at one end of the spacer post 3204 close to the workpiece 70 to be dip-coated, and the plurality of spacer grooves 3205 are arranged at intervals circumferentially around the spacer post 3204.

[0115] By setting the spacer post 3204, a gap is formed between the support plate 320 and the workpiece 70 to be dip-coated, reducing the contact area between the support plate 320 and the workpiece 70 to be dip-coated. This can not only prevent the coating from adhering the support plate 320 and the workpiece 70 to be dip-coated together, but also avoid the occurrence of dipping dead angles caused by the shielding of the support plate 320, resulting in the inability of this part of the workpiece 70 to be dip-coated with the coating; by setting a plurality of spacer grooves 3205, the contact area between the support plate 320 and the workpiece 70 to be dip-coated is further reduced, and at the same time, the coating can enter the inside of the spacer post 3204 through the spacer grooves 3205 to dip-coat the fixing post 710 and the surrounding area of the fixing post 710, thereby avoiding dipping dead angles.

[0116] As Figure 2 、 Figure 5As shown, in some embodiments, the driving unit 410 includes a translation frame 4101, a first driving module 4102, a second driving module 4103, and a third driving module 4104; the translation frame 4101 is movably arranged on the frame 10; the first driving module 4102 is configured to drive the translation frame 4101 to move in the first direction; the second driving module 4103 is arranged on the translation frame 4101; the third driving module 4104 is movably arranged on the translation frame 4101, and the second driving module 4103 is configured to drive the third driving module 4104 to move in the second direction; wherein, the hanging part 420 is arranged on the third driving module 4104, and the third driving module 4104 is configured to drive the hanging part 420 to move in the third direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0117] By driving the hanging part 420 to move in the first direction, the second direction, and the third direction respectively through the first driving module 4102, the second driving module 4103, and the third driving module 4104, the hanging part 420 can move to a specified position for operation. Specifically, the first driving module 4102 is used to drive the hanging part 420 to move in the first direction, so that the hanging part 420 can reciprocate between the feeding part 110, the material bucket assembly 20, and the discharging part 120; the second driving module 4103 and the third driving module 4104 are used to drive the hanging part 420 to move in the second direction and the third direction respectively, so that the hanging part 420 can be aligned with the feeding part 110 and the discharging part 120; at the same time, the third driving module 4104 is used to drive the hanging part 420 to move in the third direction to adjust the height of the workpiece 70 to be dip-coated on the hanging part 420 immersed in the coating.

[0118] It should be noted that the first driving module 4102 includes but is not limited to gear-rack drive, synchronous belt drive, rolling screw, or linear module structure;

The second gear meshes with the second gear; the second driving motor 4113 drives the second gear to rotate, and the second gear meshes with the second rack, thereby driving the third driving module 4104 to move in the second direction.

[0122] It should also be noted that the third driving module 4104 includes, but is not limited to, a rack and pinion drive, a synchronous belt drive, a rolling screw, or a linear module structure;

[0123] For example, as Figure 5 shown, the third driving module 4104 is a rack and pinion drive. The third driving module 4104 includes a fixed seat 4110, a third guide rail 4111, a third rack, a third gear, and a third driving motor 4112. The fixed seat 4110 is movably arranged on the second guide rail 4114. The third guide rail 4111 passes through the fixed seat 4110 and is movably arranged on the fixed seat 4110.

The third gear is arranged on the rotating shaft of the third driving motor 4112. The third gear meshes with the third rack; wherein, the hanging part 420 is arranged on the third guide rail 4111. The third driving motor 4112 drives the third gear to rotate, and the third gear meshes with the third rack, thereby driving the third guide rail 4111 to move in the third direction, and the hanging part 420 moves in the third direction along with the third guide rail 4111.

[0124] It should also be noted that, as Figure 1 shown, the first direction is parallel to the X direction, the second direction is parallel to the Y direction, and the third direction is parallel to the Z direction.

[0125] In some embodiments, as Figure 6 、 Figure 7As shown, the hanging part 420 includes a fixing plate 4201, a hanging plate 4202, and a material leveling driving member 4203; the fixing plate 4201 is arranged on the driving part 410; the hanging plate 4202 is rotatably arranged on the fixing plate 4201, and the dip coating groove 430 is arranged on one side of the hanging plate 4202; the material leveling driving members 4203 are respectively arranged on both sides of the fixing plate 4201, and the telescopic rod of the material leveling driving member 4203 is rotatably connected to the hanging plate 4202.

[0126] By arranging the fixing plate 4201 on the driving part 410, the driving part 410 can drive the hanging part 420 to move; after dip coating, the telescopic rod of the unilateral material leveling driving member 4203 extends or retracts to drive the hanging plate 4202 to rotate, so that the hanging plate 4202 deflects and tilts, and the workpiece 70 to be dip coated deflects and tilts along with the hanging plate 4202, so that the coating on the workpiece 70 to be dip coated can flow to other areas, thereby being able to remove the excess coating on the workpiece 70 to be dip coated, ensuring the consistency of the coating thickness, and preventing the coating from accumulating in a certain area of the workpiece 70 to be dip coated, causing the problem of uneven dip coating.

[0127] It should be noted that the material leveling driving member 4203 includes but is not limited to one of an electric cylinder and a cylinder; when the unilateral material leveling driving member 4203 drives the rotation angle of the material leveling driving member 4203 to be 30 - 50°, preferably, the unilateral material leveling driving member 4203 drives the rotation angle of the material leveling driving member 4203 to be 45°; in addition, as Figure 6 、 Figure 7 shown, the material leveling driving member 4203 can also be arranged only on one side of the fixing plate 4201.

[0128] It should also be noted that, as Figure 7 shown, the fixing plate 4201 includes an inner plate 4205, a slide rail, and an outer plate 4204. The inner plate 4205 is movably arranged on the third guide rail 4111, the slide rail is arranged on the inner plate 4205, and the outer plate 4204 is arranged on the slide rail through a slider; the material leveling driving member 4203 and the hanging plate 4202 are both arranged on the outer plate 4204; wherein, the slider is locked on the slide rail. When it is necessary to adjust the height of the outer plate 4204, the locking is released, the slider and the outer plate 4204 are moved to the required height, and then the slider and the slide rail are locked again.

[0129] It should also be noted that a hook is arranged on one side of the hanging plate 4202, and an immersion coating groove 430 is formed between the hook and the hanging plate 4202.

[0130] It should also be noted that, as Figure 6 shown, a housing 440 can be arranged outside the material leveling driving member 4203 and the locking driving member 540.

[0131] As Figure 7 - Figure 9As shown, in some embodiments, the dip coating device further includes a locking assembly 50. The locking assembly 50 includes a support base 510, a pressing member, and an elastic member 530. The support base 510 is disposed on a side of the hanging plate 4202 away from the dip coating groove 430. The pressing block 520 is movably disposed within the support base 510. The elastic member 530 is located within the support base 510, and two ends of the elastic member 530 are respectively connected to the support base 510 and the pressing block 520. Wherein, one end of the pressing block 520 away from the elastic member 530 passes through the support base 510 and the hanging plate 4202 to press or release the fixture assembly 30 within the dip coating groove 430.

[0132] The fixture assembly 30 is pressed or released by the locking assembly 50, which facilitates loading and unloading into and from the dip coating groove 430. Specifically, when the user loads the material, the pressing block 520 is pressed, and the pressing block 520 moves in a direction away from the dip coating groove 430. The elastic member 530 is compressed, and the fixture assembly 30 is suspended into the dip coating groove 430. The pressing block 520 is released, and the pressing block 520 moves in a direction close to the dip coating groove 430 under the action of the elastic force, and the pressing block 520 presses the fixture assembly 30.

[0133] It should be noted that the elastic member 530 includes, but is not limited to, a spring.

[0134] It should also be noted that the support base 510 is provided with a through hole for the pressing block 520 to pass through, and the hanging plate 4202 is provided with a through hole for the pressing block 520 to pass through.

[0135] As Figure 7 - Figure 9 As shown, in some embodiments, the locking assembly 50 further includes a locking driving member 540 and a pressing rod 550. The locking driving member 540 is disposed on the fixing plate 4201. One end of the pressing rod 550 is connected to the telescopic rod of the locking driving member 540, and the other end is provided with a driving inclined surface 5501. Wherein, the pressing block 520 is provided with a groove body 5201 for the pressing rod 550 to pass through, and a pressing inclined surface 5202 matching with the driving inclined surface 5501 is disposed within the groove body 5201, so that the pressing rod 550 drives the pressing block 520 to move to press or release the fixture assembly 30 within the dip coating groove 430.

[0136] The locking driving member 540 drives the pressing rod 550 to move in the third direction. By utilizing the cooperation between the driving inclined surface 5501 and the pressing inclined surface 5202, the movement in the third direction is converted into the movement in the first direction, driving the pressing block 520 to move in the first direction, so that the pressing block 520 approaches or moves away from the dip coating slot 430, thereby realizing the pressing or releasing of the fixture assembly 30. Specifically, when the workpiece 70 to be dip-coated is dip-coated in the material bucket assembly 20, the pressing block 520 presses the fixture assembly 30, and the pressing inclined surface 5202 abuts against the driving inclined surface 5501, preventing the pressing block 520 from accidentally triggering and releasing the fixture assembly 30 during the dip coating process; when picking up the fixture assembly 30 from the loading part 110, placing the fixture assembly 30 at the unloading part 120, and the material leveling driving member 4203 drives the fixture assembly 30 to tilt and deflect, the locking driving member 540 drives the pressing block 520 to release the fixture assembly 30, so as to ensure that the fixture assembly 30 can be picked up smoothly, ensure that the material leveling driving member 4203 can drive the fixture assembly 30 to tilt and deflect, and avoid jamming.

[0137] It should be noted that the locking driving member 540 includes, but is not limited to, one of an electric push rod, a cylinder, and an oil cylinder.

[0138] It should also be noted that a guiding block is provided on the fixing plate 4201, and a guiding hole is provided on the guiding block. The pressing rod 550 is matched with the guiding hole to guide the movement of the pressing rod 550 in the third direction.

[0139] In some embodiments, the dip coating device includes a vibrator 60, and the vibrator 60 is arranged on the side of the hanging plate 4202 away from the dip coating slot 430.

[0140] By arranging the vibrator 60 to drive the workpiece 70 to be dip-coated to vibrate after the dip coating is completed, the excess coating on the workpiece 70 to be dip-coated is removed, ensuring the uniformity of the dip coating of the workpiece 70 to be dip-coated and the consistency of the coating thickness.

[0141] It should be noted that the vibrators 60 are respectively located on both sides of the support seat 510.

[0142] It should also be noted that after the dip coating is completed, the coating thickness can be tested by infrared spectroscopy. Specifically, the thickness is deduced by using the absorption characteristics of infrared light in the coating.

[0143] Such as Figure 1As shown, in some embodiments, the rack 10 includes a main frame body having a loading end and an unloading end oppositely arranged in the first direction. The loading part 110 and the unloading part 120 are both located within the main frame body. Among them, safety light curtains 130 are provided at both the loading end and the unloading end to play a protective role. For example, if someone touches the light curtain, the dip coating device will stop operating. In addition, the main frame body has an inlet end and an outlet end oppositely arranged in the second direction. Protective doors 140 are provided at both the inlet end and the outlet end. By opening the protective door 140, the paint can be added to the bucket assembly 20 and the bucket assembly 20 can be carried.

[0144] As Figure 5 As shown, in some embodiments, the bucket assembly 20 includes a positioning frame 210 arranged within the main frame body and a bucket 220 arranged within the positioning frame 210. One end of the positioning frame 210 is provided with an opening, and the opening is provided with an inclined guiding surface to facilitate the placement of the bucket 220. A buffer pad is arranged on the inner wall of the positioning frame 210 to play a role in shock absorption and buffering during the handling of the bucket 220 to prevent the bucket 220 from being knocked.
