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

[0061] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid. When the surface temperature of the heat exchanger is 10-15°C lower than the air temperature, condensation occurs, leading to corrosion. To prevent condensation, a layer of insulating cotton is usually manually wrapped around the surface of the heat exchanger and piping for insulation. However, due to the wide variety and complex structure of heat exchangers, this method is cumbersome, labor-intensive, and inefficient. Therefore, it has been proposed to impregnate the heat exchanger surface with insulating coating to replace the sponge wrapping. However, the current common practice is to manually impregnate the heat exchanger, which is labor-intensive, inefficient, and cannot guarantee the quality of the workpiece.

[0062] Example 1

[0063] like Figure 1 , Figure 2As shown, to solve the above-mentioned technical problems, this utility model provides a dip coating apparatus, including a frame 10, a material bucket assembly 20, a hanger assembly 30, and a transfer assembly 40; the frame 10 includes a loading section 110 and a unloading section 120; the material bucket assembly 20 is disposed between the loading section 110 and the unloading section 120, and the material bucket assembly 20 contains coating material; the hanger assembly 30 is configured to suspend the workpiece 70 to be dip coated; the transfer assembly 40 includes a drive unit 410. The mounting part 420 is provided on the drive unit 410; wherein, the mounting assembly 30 is configured to be mounted on the loading unit 110, the unloading unit 120 and the mounting part 420 respectively, and the drive unit 410 is configured to drive the mounting part 420 to reciprocate between the loading unit 110, the material barrel assembly 20 and the unloading unit 120, and drive the mounting part 420 to enter and exit the material barrel assembly 20, so as to pick up and put down the mounting assembly 30, and to load, unload and dip coat the workpiece 70 to be dip coated.

[0064] As can be seen from the above, the drive unit 410 drives the hooking unit 420 to reciprocate between the loading unit 110, the material bucket assembly 20, and the unloading unit 120, thereby picking up the hanger assembly 30 and transferring the hanger assembly 30 and the workpiece 70 suspended on it to be dipped and coated, thus realizing the loading and unloading of the workpiece 70 to be dipped and coated; specifically, the drive unit 410 drives the hooking unit 420 to the loading unit 110, picks up the hanger assembly 30 of the loading unit 110, and drives the hanger assembly 30 and the workpiece 70 suspended on it to the material bucket assembly 20, thus realizing the loading of the workpiece 70 to be dipped and coated; the drive unit 410 drives the hooking unit 420 to the unloading unit 120, and the unloading unit 120 picks up the hanger assembly 30 of the hooking unit 420, thus realizing the unloading of the workpiece 70 to be dipped and coated. The drive unit 410 drives the feeding / discharging hopper assembly 20 of the hook-and-mount part 420, immersing the workpiece 70 to be coated on the hook-and-mount part 420 in the coating material for coating, thereby achieving dip coating. Therefore, this utility model can automatically realize feeding, unloading and dip coating, greatly reducing manual handling of the workpiece 70 to be coated, thus effectively reducing labor intensity, improving production efficiency, and controlling the movement path of the workpiece 70 to be coated, eliminating bumps during the dip coating process, and ensuring the stable quality of the workpiece 70 to be 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 consisting of a series of metal sheets with a certain corrugated shape stacked together. One side of the plate heat exchanger is provided with a connecting joint and a heat exchange tube connected to the connecting joint. In addition, before dip-coating, rubber caps are used to wrap the connecting joints without heat exchange tubes and the ends of the heat exchange tubes away from the connecting joints to prevent the coating from entering.

[0066] It should also be noted that the coating inside the material barrel assembly 20 can be a heat-insulating coating, for example, a ceramic microsphere type heat-insulating coating, which has the characteristics of being hollow, lightweight, and having low thermal conductivity. It can not only block heat but also improve the heat insulation performance of the coating film, thus achieving a combined effect of emitting sunlight and blocking heat.

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

[0068] It should also be noted that the surface of the hanging assembly 30 may be coated with a non-stick coating, so that the hanging assembly 30 can be easily cleaned after the paint adheres to it.

[0069] Example 2

[0070] like Figure 1 , Figure 2 As shown, the dip coating apparatus includes a frame 10, a material tank assembly 20, a hanger assembly 30, and a transfer assembly 40. The frame 10 includes a loading section 110 and a unloading section 120. The material tank assembly 20 is disposed between the loading section 110 and the unloading section 120, and contains coating material. The hanger assembly 30 is configured to suspend the workpiece 70 to be dip coated. The transfer assembly 40 includes a drive section 410 and a hooking section 420 disposed on the drive section 410. The hanger assembly 30 is configured to be hung on the loading section 110, the unloading section 120, and the hooking section 420 respectively. The drive section 410 is configured to drive the hooking section 420 to reciprocate between the loading section 110, the material tank assembly 20, and the unloading section 120, and to drive the hooking section 420 to enter and exit the material tank assembly 20, so as to pick up and place the hanger assembly 30, and to load, unload, and dip coat the workpiece 70 to be dip coated.

[0071] As can be seen from the above, the drive unit 410 drives the hooking unit 420 to reciprocate between the loading unit 110, the material bucket assembly 20, and the unloading unit 120, thereby picking up the hanger assembly 30 and transferring the hanger assembly 30 and the workpiece 70 suspended on it to be dipped and coated, thus realizing the loading and unloading of the workpiece 70 to be dipped and coated; specifically, the drive unit 410 drives the hooking unit 420 to the loading unit 110, picks up the hanger assembly 30 of the loading unit 110, and drives the hanger assembly 30 and the workpiece 70 suspended on it to the material bucket assembly 20, thus realizing the loading of the workpiece 70 to be dipped and coated; the drive unit 410 drives the hooking unit 420 to the unloading unit 120, and the unloading unit 120 picks up the hanger assembly 30 of the hooking unit 420, thus realizing the unloading of the workpiece 70 to be dipped and coated. The drive unit 410 drives the feeding / discharging hopper assembly 20 of the hook-and-mount part 420, immersing the workpiece 70 to be coated on the hook-and-mount part 420 in the coating material for coating, thereby achieving dip coating. Therefore, this utility model can automatically realize feeding, unloading and dip coating, greatly reducing manual handling of the workpiece 70 to be coated, thus effectively reducing labor intensity, improving production efficiency, and controlling the movement path of the workpiece 70 to be coated, eliminating bumps during the dip coating process, and ensuring the stable quality of the workpiece 70 to be coated.

[0072] 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 consisting of a series of metal sheets with a certain corrugated shape stacked together. One side of the plate heat exchanger is provided with a connecting joint and a heat exchange tube connected to the connecting joint. In addition, before dip-coating, rubber caps are used to wrap the connecting joints without heat exchange tubes and the ends of the heat exchange tubes away from the connecting joints to prevent the coating from entering.

[0073] It should also be noted that the coating inside the material barrel assembly 20 can be a heat-insulating coating, for example, a ceramic microsphere type heat-insulating coating, which has the characteristics of being hollow, lightweight, and having low thermal conductivity. It can not only block heat but also improve the heat insulation performance of the coating film, thus achieving a combined effect of emitting sunlight and blocking heat.

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

[0075] It should also be noted that the surface of the hanging assembly 30 may be coated with a non-stick coating, so that the hanging assembly 30 can be easily cleaned after the paint adheres to it.

[0076] like Figure 3 , Figure 4 , Figure 6 , Figure 10 , Figure 11As shown, in some embodiments, the hanger assembly 30 includes a hanger 310 and a support plate 320; one end of the support plate 320 is connected to the hanger 310, and the support plate 320 is configured to be detachably connected to the workpiece 70 to be dipped and coated; wherein, the loading part 110, the unloading part 120, and the hanging part 420 are respectively provided with a loading groove 1101, an unloading groove 1201, and a dipping and coating groove 430 for the hanger 310 to be inserted.

[0077] The hanging rack 310, the loading rack 1101, the unloading rack 1201 and the dipping rack 430 provide a structural basis for the suspension of the hanging fixture assembly 30. The detachable connection between the support plate 320 and the workpiece 70 to be dipped and coated allows the hanging fixture assembly 30 to be reused during the coating process.

[0078] It should be noted that, as Figure 10 As shown, the hanger 310 includes a hanging rod and a transition rod perpendicularly connected to the hanging rod, so that the hanger 310 is T-shaped. The transition rod is provided with a weight reduction hole. The hanging rod can be inserted into the loading groove 1101, the unloading groove 1201, and the coating groove 430 to achieve suspension.

[0079] It should also be noted that, such as Figure 2 , Figure 3 As shown, the feeding part 110 includes a feeding rack 1102, and the feeding hanging groove 1101 includes a first through groove 1105 and a first limiting groove 1103 disposed on the feeding rack 1102. The first limiting groove 1103 is located on both sides of the first through groove 1105, and the opposite inner walls of the first limiting groove 1103 are respectively provided with first guide slopes 1104. The first through groove 1105 provides space for the hanging part 420 to pick up the hanging fixture assembly 30, avoiding interference and preventing the hanging part 420 from picking up the hanging fixture assembly 30 smoothly. The first limiting groove 1103 plays a fixed limiting role for the hanging fixture assembly 30, preventing the hanging fixture assembly 30 from falling. The first guide slope 1104 plays a guiding role when the hanging frame 310 is inserted into the first limiting groove 1103, which facilitates the hanging of the hanging frame 310.

[0080] It should also be noted that, such as Figure 2 , Figure 4As shown, the unloading part 120 includes an unloading frame 1202, and the unloading hanging groove 1201 includes a second through groove 1206 and a second limiting groove 1204 disposed on the unloading frame 1202. The second limiting groove 1204 is located on both sides of the second through groove 1206, and a second guide slope 1205 is disposed on the opposite inner wall of the second limiting groove 1204. The second through groove 1206 provides space for the hanging part 420 to pick up the hanging fixture assembly 30 to avoid interference, which would prevent the hanging part 420 from picking up the hanging fixture assembly 30 smoothly. The second limiting groove 1204 fixes and limits the hanging fixture assembly 30 to prevent it from falling. The second guide slope 1205 guides the hanging frame 310 during the insertion of the hanging frame 310 into the second limiting groove 1204, making it easier for the hanging frame 310 to hang.

[0081] It should also be noted that, such as Figure 2 As shown, the unloading section 120 also includes a receiving tray 1203 set on the unloading rack 1202. The receiving tray 1203 is provided with a receiving trough for collecting paint. The bottom of the receiving trough is provided with a converging slope so that the paint dripping from the workpiece 70 to be dipped can quickly flow together and be recycled by the staff.

[0082] like Figure 10 As shown, in some embodiments, the end of the support plate 320 away from the hanger 310 is provided with a clearance groove 3201, and the support plate 320 is provided with a support hole for the fixing post 710 of the workpiece 70 to be dipped and coated to pass through; wherein, the hanger assembly 30 also includes a fastener 3203, which is connected to the fixing post 710 so as to fix the workpiece 70 to be dipped and coated on the support plate 320.

[0083] By setting the clearance groove 3201 to reserve the immersion position for the workpiece 70 to be immersed, all parts of the workpiece to be immersed can be submerged in the paint and in contact with the paint, avoiding the formation of immersion dead corners due to the obstruction of the support plate 320, which would prevent the workpiece 70 from being immersed in the paint.

[0084] It should be noted that the fixing column 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, which is threadedly connected to the fixing column 710, thereby fixing the workpiece 70 to be dipped and coated onto the support plate 320.

[0085] It should also be noted that, such as Figure 10 As shown, the support holes are located on both sides of the clearance groove 3201.

[0086] like Figure 11As shown, in some embodiments, the hanger assembly 30 further includes a spacer post 3204, which is sleeved outside the fixed post 710. The two ends of the spacer post 3204 abut against the support plate 320 and the workpiece 70 to be dipped and coated, respectively. The spacer post 3204 has a plurality of spacer grooves 3205 at one end near the workpiece 70 to be dipped and coated, and the plurality of spacer grooves 3205 are arranged circumferentially around the spacer post 3204.

[0087] By setting the gap column 3204, a gap is created between the support plate 320 and the workpiece 70 to be dipped, reducing the contact area between the support plate 320 and the workpiece 70 to be dipped. This not only prevents the paint from adhering to the support plate 320 and the workpiece 70 to be dipped, but also avoids the situation where the workpiece 70 cannot be dipped due to the obstruction of the support plate 320. By setting multiple gap grooves 3205, the contact area between the support plate 320 and the workpiece 70 to be dipped is further reduced. At the same time, the paint can enter the interior of the gap column 3204 through the gap grooves 3205 to dip the fixed column 710 and the surrounding area of ​​the fixed column 710, thereby avoiding the dipping dead corner.

[0088] like Figure 2 , Figure 5 As shown, in some embodiments, the drive unit 410 includes a translation frame 4101, a first drive module 4102, a second drive module 4103, and a third drive module 4104; the translation frame 4101 is movably mounted on the frame 10; the first drive module 4102 is configured to drive the translation frame 4101 to move along a first direction; the second drive module 4103 is mounted on the translation frame 4101; the third drive module 4104 is movably mounted on the translation frame 4101, and the second drive module 4103 is configured to drive the third drive module 4104 to move along a second direction; wherein, the mounting part 420 is mounted on the third drive module 4104, and the third drive module 4104 is configured to drive the mounting part 420 to move along a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0089] The first drive module 4102, the second drive module 4103, and the third drive module 4104 respectively drive the mounting part 420 to move upward in the first direction, the second direction, and the third direction, respectively, so that the mounting part 420 can move to a designated position for operation. Specifically, the first drive module 4102 drives the mounting part 420 to move in the first direction, so that the mounting part 420 can reciprocate between the loading part 110, the material barrel assembly 20, and the unloading part 120; the second drive module 4103 and the third drive module 4104 respectively drive the mounting part 420 to move in the second direction and the third direction, so that the mounting part 420 can be aligned with the loading part 110 and the unloading part 120; at the same time, the third drive module 4104 drives the mounting part 420 to move in the third direction, adjusting the height of the workpiece 70 to be coated on the mounting part 420 immersed in the coating.

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

[0091] For example, such as Figure 2 As shown, the first drive module 4102 is a rack and pinion drive. The first drive module 4102 includes a first drive shaft 4105, a first guide rail 4106, a first rack 4107, a first drive motor 4108, and a first gear 4109. The first drive shaft 4105 is rotatably mounted on the translation frame 4101. The first drive motor 4108 is connected to the first drive shaft 4105. The first gear 4109 is respectively mounted at both ends of the first drive shaft 4105. The first guide rail 4106 and the first rack 4107 are both mounted on the frame 10. The translation frame 4101 is movably mounted on the first guide rail 4106. The first rack 4107 meshes with the first gear 4109. The first drive motor 4108 drives the first gear 4109 to rotate. The first gear 4109 meshes with the first rack 4107, thereby driving the translation frame 4101 to move along the first direction.

[0092] It should also be noted that the second drive module 4103 includes, but is not limited to, gear and rack drive, synchronous belt drive, rolling screw, or linear module structure;

[0093] For example, such as Figure 5As shown, the second drive module 4103 is a rack and pinion drive. The second drive module 4103 includes a second guide rail 4114, a second rack, a second drive motor 4113, and a second gear. The third drive module 4104 is movably mounted on the second guide rail 4114. The second rack is mounted on the translation frame 4101. The second drive motor 4113 is mounted on the third drive module 4104. The second gear is mounted on the rotating shaft of the second drive motor 4113. The second gear meshes with the second gear. The second drive motor 4113 drives the second gear to rotate, and the second gear meshes with the second rack, thereby driving the third drive module 4104 to move along the second direction.

[0094] It should also be noted that the third drive module 4104 includes, but is not limited to, gear and rack drive, synchronous belt drive, rolling screw, or linear module structure;

[0095] For example, such as Figure 5 As shown, the third drive module 4104 is a rack and pinion drive. The third drive module 4104 includes a fixed base 4110, a third guide rail 4111, a third rack, a third gear, and a third drive motor 4112. The fixed base 4110 is movably mounted on the second guide rail 4114. The third guide rail 4111 passes through the fixed base 4110 and is movably mounted on the fixed base 4110. The third rack is mounted on the third guide rail 4111. The third drive motor 4112 is mounted on the translation frame 4101. The third gear is mounted on the rotating shaft of the third drive motor 4112, and the third gear meshes with the third rack. The hook part 420 is mounted on the third guide rail 4111. The third drive 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 a third direction. The hook part 420 moves with the third guide rail 4111 in the third direction.

[0096] It should also be noted that, such as Figure 1 As 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.

[0097] Example 3

[0098] like Figure 1 , Figure 2As shown, the dip coating apparatus includes a frame 10, a material tank assembly 20, a hanger assembly 30, and a transfer assembly 40. The frame 10 includes a loading section 110 and a unloading section 120. The material tank assembly 20 is disposed between the loading section 110 and the unloading section 120, and contains coating material. The hanger assembly 30 is configured to suspend the workpiece 70 to be dip coated. The transfer assembly 40 includes a drive section 410 and a hooking section 420 disposed on the drive section 410. The hanger assembly 30 is configured to be hung on the loading section 110, the unloading section 120, and the hooking section 420 respectively. The drive section 410 is configured to drive the hooking section 420 to reciprocate between the loading section 110, the material tank assembly 20, and the unloading section 120, and to drive the hooking section 420 to enter and exit the material tank assembly 20, so as to pick up and place the hanger assembly 30, and to load, unload, and dip coat the workpiece 70 to be dip coated.

[0099] As can be seen from the above, the drive unit 410 drives the hooking unit 420 to reciprocate between the loading unit 110, the material bucket assembly 20, and the unloading unit 120, thereby picking up the hanger assembly 30 and transferring the hanger assembly 30 and the workpiece 70 suspended on it to be dipped and coated, thus realizing the loading and unloading of the workpiece 70 to be dipped and coated; specifically, the drive unit 410 drives the hooking unit 420 to the loading unit 110, picks up the hanger assembly 30 of the loading unit 110, and drives the hanger assembly 30 and the workpiece 70 suspended on it to the material bucket assembly 20, thus realizing the loading of the workpiece 70 to be dipped and coated; the drive unit 410 drives the hooking unit 420 to the unloading unit 120, and the unloading unit 120 picks up the hanger assembly 30 of the hooking unit 420, thus realizing the unloading of the workpiece 70 to be dipped and coated. The drive unit 410 drives the feeding / discharging hopper assembly 20 of the hook-and-mount part 420, immersing the workpiece 70 to be coated on the hook-and-mount part 420 in the coating material for coating, thereby achieving dip coating. Therefore, this utility model can automatically realize feeding, unloading and dip coating, greatly reducing manual handling of the workpiece 70 to be coated, thus effectively reducing labor intensity, improving production efficiency, and controlling the movement path of the workpiece 70 to be coated, eliminating bumps during the dip coating process, and ensuring the stable quality of the workpiece 70 to be 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 consisting of a series of metal sheets with a certain corrugated shape stacked together. One side of the plate heat exchanger is provided with a connecting joint and a heat exchange tube connected to the connecting joint. In addition, before dip-coating, rubber caps are used to wrap the connecting joints without heat exchange tubes and the ends of the heat exchange tubes away from the connecting joints to prevent the coating from entering.

[0101] It should also be noted that the coating inside the material barrel assembly 20 can be a heat-insulating coating, for example, a ceramic microsphere type heat-insulating coating, which has the characteristics of being hollow, lightweight, and having low thermal conductivity. It can not only block heat but also improve the heat insulation performance of the coating film, thus achieving a combined effect of emitting sunlight and blocking heat.

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

[0103] It should also be noted that the surface of the hanging assembly 30 may be coated with a non-stick coating, so that the hanging assembly 30 can be easily cleaned after the paint adheres to it.

[0104] like Figure 3 , Figure 4 , Figure 6 , Figure 10 , Figure 11 As shown, in some embodiments, the hanger assembly 30 includes a hanger 310 and a support plate 320; one end of the support plate 320 is connected to the hanger 310, and the support plate 320 is configured to be detachably connected to the workpiece 70 to be dipped and coated; wherein, the loading part 110, the unloading part 120, and the hanging part 420 are respectively provided with a loading groove 1101, an unloading groove 1201, and a dipping and coating groove 430 for the hanger 310 to be inserted.

[0105] The hanging rack 310, the loading rack 1101, the unloading rack 1201 and the dipping rack 430 provide a structural basis for the suspension of the hanging fixture assembly 30. The detachable connection between the support plate 320 and the workpiece 70 to be dipped and coated allows the hanging fixture assembly 30 to be reused during the coating process.

[0106] It should be noted that, as Figure 10 As shown, the hanger 310 includes a hanging rod and a transition rod perpendicularly connected to the hanging rod, so that the hanger 310 is T-shaped. The transition rod is provided with a weight reduction hole. The hanging rod can be inserted into the loading groove 1101, the unloading groove 1201, and the coating groove 430 to achieve suspension.

[0107] It should also be noted that, such as Figure 2 , Figure 3As shown, the feeding part 110 includes a feeding rack 1102, and the feeding hanging groove 1101 includes a first through groove 1105 and a first limiting groove 1103 disposed on the feeding rack 1102. The first limiting groove 1103 is located on both sides of the first through groove 1105, and the opposite inner walls of the first limiting groove 1103 are respectively provided with first guide slopes 1104. The first through groove 1105 provides space for the hanging part 420 to pick up the hanging fixture assembly 30, avoiding interference and preventing the hanging part 420 from picking up the hanging fixture assembly 30 smoothly. The first limiting groove 1103 plays a fixed limiting role for the hanging fixture assembly 30, preventing the hanging fixture assembly 30 from falling. The first guide slope 1104 plays a guiding role when the hanging frame 310 is inserted into the first limiting groove 1103, which facilitates the hanging of the hanging frame 310.

[0108] It should also be noted that, such as Figure 2 , Figure 4 As shown, the unloading part 120 includes an unloading frame 1202, and the unloading hanging groove 1201 includes a second through groove 1206 and a second limiting groove 1204 disposed on the unloading frame 1202. The second limiting groove 1204 is located on both sides of the second through groove 1206, and a second guide slope 1205 is disposed on the opposite inner wall of the second limiting groove 1204. The second through groove 1206 provides space for the hanging part 420 to pick up the hanging fixture assembly 30 to avoid interference, which would prevent the hanging part 420 from picking up the hanging fixture assembly 30 smoothly. The second limiting groove 1204 fixes and limits the hanging fixture assembly 30 to prevent it from falling. The second guide slope 1205 guides the hanging frame 310 during the insertion of the hanging frame 310 into the second limiting groove 1204, making it easier for the hanging frame 310 to hang.

[0109] It should also be noted that, such as Figure 2 As shown, the unloading section 120 also includes a receiving tray 1203 set on the unloading rack 1202. The receiving tray 1203 is provided with a receiving trough for collecting paint. The bottom of the receiving trough is provided with a converging slope so that the paint dripping from the workpiece 70 to be dipped can quickly flow together and be recycled by the staff.

[0110] like Figure 10 As shown, in some embodiments, the end of the support plate 320 away from the hanger 310 is provided with a clearance groove 3201, and the support plate 320 is provided with a support hole for the fixing post 710 of the workpiece 70 to be dipped and coated to pass through; wherein, the hanger assembly 30 also includes a fastener 3203, which is connected to the fixing post 710 so as to fix the workpiece 70 to be dipped and coated on the support plate 320.

[0111] By setting the clearance groove 3201 to reserve the immersion position for the workpiece 70 to be immersed, all parts of the workpiece to be immersed can be submerged in the paint and in contact with the paint, avoiding the formation of immersion dead corners due to the obstruction of the support plate 320, which would prevent the workpiece 70 from being immersed in the paint.

[0112] It should be noted that the fixing column 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, which is threadedly connected to the fixing column 710, thereby fixing the workpiece 70 to be dipped and coated onto the support plate 320.

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

[0114] like Figure 11 As shown, in some embodiments, the hanger assembly 30 further includes a spacer post 3204, which is sleeved outside the fixed post 710. The two ends of the spacer post 3204 abut against the support plate 320 and the workpiece 70 to be dipped and coated, respectively. The spacer post 3204 has a plurality of spacer grooves 3205 at one end near the workpiece 70 to be dipped and coated, and the plurality of spacer grooves 3205 are arranged circumferentially around the spacer post 3204.

[0115] By setting the gap column 3204, a gap is created between the support plate 320 and the workpiece 70 to be dipped, reducing the contact area between the support plate 320 and the workpiece 70 to be dipped. This not only prevents the paint from adhering to the support plate 320 and the workpiece 70 to be dipped, but also avoids the situation where the workpiece 70 cannot be dipped due to the obstruction of the support plate 320. By setting multiple gap grooves 3205, the contact area between the support plate 320 and the workpiece 70 to be dipped is further reduced. At the same time, the paint can enter the interior of the gap column 3204 through the gap grooves 3205 to dip the fixed column 710 and the surrounding area of ​​the fixed column 710, thereby avoiding the dipping dead corner.

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

[0117] The first drive module 4102, the second drive module 4103, and the third drive module 4104 respectively drive the mounting part 420 to move upward in the first direction, the second direction, and the third direction, respectively, so that the mounting part 420 can move to a designated position for operation. Specifically, the first drive module 4102 drives the mounting part 420 to move in the first direction, so that the mounting part 420 can reciprocate between the loading part 110, the material barrel assembly 20, and the unloading part 120; the second drive module 4103 and the third drive module 4104 respectively drive the mounting part 420 to move in the second direction and the third direction, so that the mounting part 420 can be aligned with the loading part 110 and the unloading part 120; at the same time, the third drive module 4104 drives the mounting part 420 to move in the third direction, adjusting the height of the workpiece 70 to be coated on the mounting part 420 immersed in the coating.

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

[0119] For example, such as Figure 2 As shown, the first drive module 4102 is a rack and pinion drive. The first drive module 4102 includes a first drive shaft 4105, a first guide rail 4106, a first rack 4107, a first drive motor 4108, and a first gear 4109. The first drive shaft 4105 is rotatably mounted on the translation frame 4101. The first drive motor 4108 is connected to the first drive shaft 4105. The first gear 4109 is respectively mounted at both ends of the first drive shaft 4105. The first guide rail 4106 and the first rack 4107 are both mounted on the frame 10. The translation frame 4101 is movably mounted on the first guide rail 4106. The first rack 4107 meshes with the first gear 4109. The first drive motor 4108 drives the first gear 4109 to rotate. The first gear 4109 meshes with the first rack 4107, thereby driving the translation frame 4101 to move along the first direction.

[0120] It should also be noted that the second drive module 4103 includes, but is not limited to, gear and rack drive, synchronous belt drive, rolling screw, or linear module structure;

[0121] For example, such as Figure 5 As shown, the second drive module 4103 is a rack and pinion drive. The second drive module 4103 includes a second guide rail 4114, a second rack, a second drive motor 4113, and a second gear. The third drive module 4104 is movably mounted on the second guide rail 4114. The second rack is mounted on the translation frame 4101. The second drive motor 4113 is mounted on the third drive module 4104. The second gear is mounted on the rotating shaft of the second drive motor 4113. The second gear meshes with the second gear. The second drive motor 4113 drives the second gear to rotate, and the second gear meshes with the second rack, thereby driving the third drive module 4104 to move along the second direction.

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

[0123] For example, such as Figure 5 As shown, the third drive module 4104 is a rack and pinion drive. The third drive module 4104 includes a fixed base 4110, a third guide rail 4111, a third rack, a third gear, and a third drive motor 4112. The fixed base 4110 is movably mounted on the second guide rail 4114. The third guide rail 4111 passes through the fixed base 4110 and is movably mounted on the fixed base 4110. The third rack is mounted on the third guide rail 4111. The third drive motor 4112 is mounted on the translation frame 4101. The third gear is mounted on the rotating shaft of the third drive motor 4112, and the third gear meshes with the third rack. The hook part 420 is mounted on the third guide rail 4111. The third drive 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 a third direction. The hook part 420 moves with the third guide rail 4111 in the third direction.

[0124] It should also be noted that, such as Figure 1 As 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, such as Figure 6 , Figure 7As shown, the mounting part 420 includes a fixing plate 4201, a hanging plate 4202, and a material leveling drive 4203; the fixing plate 4201 is disposed on the drive part 410; the hanging plate 4202 is rotatably disposed on the fixing plate 4201, and the dip coating groove 430 is disposed on one side of the hanging plate 4202; the material leveling drive 4203 is disposed on both sides of the fixing plate 4201, and the telescopic rod of the material leveling drive 4203 is rotatably connected to the hanging plate 4202.

[0126] By setting the fixing plate 4201 on the driving part 410, the driving part 410 can drive the hanging part 420 to move. After the dip coating is completed, the extension or retraction of the telescopic rod of the single-sided uniform material driving member 4203 drives the hanging plate 4202 to rotate, causing the hanging plate 4202 to deflect and tilt. The workpiece 70 to be dip coated tilts and deflects with the hanging plate 4202, allowing the coating on the workpiece 70 to flow to other areas. This removes excess coating from the workpiece 70, ensuring the consistency of the coating thickness and preventing coating from accumulating in a certain area of ​​the workpiece 70, which would cause uneven dip coating.

[0127] It should be noted that the material leveling drive 4203 includes, but is not limited to, one of an electric cylinder or a pneumatic cylinder; when the rotation angle of the material leveling drive 4203 driven by one side is 30-50°, preferably, the rotation angle of the material leveling drive 4203 driven by one side is 45°; in addition, such as Figure 6 , Figure 7 Alternatively, the material leveling drive 4203 can be installed on only one side of the fixed plate 4201.

[0128] It should also be noted that, such as Figure 7 As shown, the fixed plate 4201 includes an inner plate 4205, a slide rail, and an outer plate 4204. The inner plate 4205 is movably mounted on the third guide rail 4111, the slide rail is mounted on the inner plate 4205, and the outer plate 4204 is mounted on the slide rail via a slider. The material leveling drive 4203 and the hanging plate 4202 are both mounted on the outer plate 4204. The slider is locked to 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 provided on one side of the hanging plate 4202, and a coating groove 430 is formed between the hook and the hanging plate 4202.

[0130] It should also be noted that, such as Figure 6 As shown, a cover 440 can be provided outside the material leveling drive 4203 and the locking drive 540.

[0131] like Figures 7-9As shown, in some embodiments, the dip coating apparatus further includes a locking assembly 50, which includes a support base 510, a clamping member, and an elastic member 530. The support base 510 is disposed on the side of the hanging plate 4202 away from the dip coating tank 430. The clamping block 520 is movably disposed within the support base 510. The elastic member 530 is located within the support base 510, and its two ends are respectively connected to the support base 510 and the clamping block 520. The end of the clamping block 520 away from the elastic member 530 passes through the support base 510 and the hanging plate 4202 to clamp or loosen the hanger assembly 30 in the dip coating tank 430.

[0132] The locking component 50 can be used to press or release the hanging assembly 30, facilitating the loading and unloading of materials into the dip coating tank 430. Specifically, when the user loads materials, pressing the pressing block 520 causes it to move away from the dip coating tank 430, compressing the elastic element 530 and suspending the hanging assembly 30 into the dip coating tank 430. Releasing the pressing block 520 causes it to move closer to the dip coating tank 430 under the action of elastic force, thus pressing the hanging assembly 30.

[0133] It should be noted that the elastic element 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 clamping block 520 to pass through, and the hanging plate 4202 is provided with a through hole for the clamping block 520 to pass through.

[0135] like Figures 7-9 As shown, in some embodiments, the locking assembly 50 further includes a locking drive 540 and a pressure rod 550; the locking drive 540 is disposed on the fixed plate 4201; one end of the pressure rod 550 is connected to the telescopic rod of the locking drive 540, and the other end is provided with a driving inclined surface 5501; wherein, the pressing block 520 is provided with a groove 5201 for the pressure rod 550 to pass through, and a pressing inclined surface 5202 that cooperates with the driving inclined surface 5501 is provided in the groove 5201, so that the pressure rod 550 drives the pressing block 520 to move, pressing or releasing the hanger assembly 30 in the dip coating hanging groove 430.

[0136] The locking drive 540 drives the pressure rod 550 to move upward in the third direction. By utilizing the cooperation between the drive inclined surface 5501 and the pressing inclined surface 5202, the upward movement in the third direction is converted into movement in the first direction, which drives the pressing block 520 to move in the first direction, so that the pressing block 520 moves closer to or further away from the dip coating tank 430, thereby achieving the pressing or releasing of the hanger assembly 30. Specifically, when the workpiece 70 to be dipped is dipped in the material barrel assembly 20, the clamping block 520 clamps the hanger assembly 30, and the clamping inclined surface 5202 abuts against the driving inclined surface 5501 to prevent the clamping block 520 from being accidentally triggered and releasing the hanger assembly 30 during the dipping process; when the hanger assembly 30 is picked up from the loading part 110, placed in the loading part 120, and the uniform material driving component 4203 drives the hanger assembly 30 to tilt and deflect, the locking driving component 540 drives the clamping block 520 to release the hanger assembly 30, thereby ensuring that the hanger assembly 30 can be picked up smoothly and that the uniform material driving component 4203 can drive the hanger assembly 30 to tilt and deflect, avoiding jamming.

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

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

[0139] In some embodiments, the dip coating apparatus includes a vibrator 60 disposed on the side of the hanging plate 4202 away from the dip coating tank 430.

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

[0141] It should be noted that the vibrators 60 are located on both sides of the support base 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 can be estimated by utilizing the absorption characteristics of infrared light in the coating.

[0143] like Figure 1As shown, in some embodiments, the frame 10 includes a main frame body with a loading end and a unloading end arranged opposite each other in a first direction. The loading part 110 and the unloading part 120 are both located within the main frame body. Both the loading end and the unloading end are equipped with safety light curtains 130 for protection; if someone touches the light curtain, the coating device stops operating. Additionally, the main frame body has an inlet end and an outlet end arranged opposite each other in a second direction. Both the inlet end and the outlet end are equipped with protective doors 140. By opening the protective doors 140, paint can be added to the material tank assembly 20, and the material tank assembly 20 can be moved.

[0144] like Figure 5 As shown, in some embodiments, the material bucket assembly 20 includes a positioning frame 210 disposed in the main frame body and a material bucket 220 disposed in the positioning frame 210; one end of the positioning frame 210 is provided with an opening, and the opening is provided with an inclined guide surface to facilitate the placement of the material bucket 220; a buffer pad is provided on the inner wall of the positioning frame 210 to play a shock absorption and buffering role during the handling of the material bucket 220 and to prevent the material bucket 220 from bumping.

[0145] like Figure 5 As shown, in some embodiments, the material tank assembly 20 further includes a monitoring frame 230 and a distance sensor 240. The monitoring frame 230 is mounted on the positioning frame 210, and the distance sensor 240 is mounted on the monitoring frame 230. The distance sensor 240 is used to monitor the liquid level in the material tank 220 in real time. When the liquid level drops to a preset height, it reminds the operator to add coating to avoid the situation where the workpiece 70 to be coated is not completely covered by the coating. For example, the preset height can be half the height of the tank.

[0146] It should be noted that the dip coating unit also includes an electrical control cabinet, which is used to control the operation of the dip coating unit.

[0147] In summary, this utility model improves efficiency, reduces labor intensity, and ensures workpiece quality by using a dip-coating device to perform operations such as loading, dip-coating, and unloading of the workpiece 70 to be dip-coated. Specifically, the workpiece 70 to be dip-coated is installed on the hanger 310, and the hanger assembly 30 is suspended in the loading slot 1101 of the loading section 110; the drive unit 410 drives the connecting part 420 to move to the loading section 110, aligning the dip-coating slot 430 with the bottom of the hanger 310, and then drives the connecting part 420 upward, so that the hanger 310 enters the dip-coating slot 430, thereby transferring the hanger assembly 30 into the dip-coating slot 430, realizing the loading of the workpiece 70 to be dip-coated; the drive unit 410 drives the connecting part 420 to move to the material tank 220, driving the workpiece 70 to be dip-coated downward, so that the workpiece 70 to be dip-coated is immersed in the coating, thereby performing the dip-coating process. After the coating process is completed, the drive unit 410 moves the workpiece 70 to be coated away from the coating material. The vibrator 60 vibrates the workpiece 70 to remove excess coating material. The uniform material drive unit 4203 causes the workpiece 70 to be coated to deflect and tilt, further removing excess coating material. Then, the drive unit 410 moves the hanging part 420 to the unloading part 120, aligns the hanger 310 with the unloading groove 1201 of the unloading part 120, and moves the hanging part 420 downward, so that the hanger 310 enters the unloading groove 1201, thereby transferring the hanger assembly 30 into the unloading groove 1201 and realizing the unloading of the workpiece 70 to be coated.

[0148] Example 4

[0149] This utility model embodiment also provides a coating system, including the dip coating device of any embodiment of this utility model, thereby having all the technical effects brought about by the technical solutions of the above embodiments.

[0150] It should be noted that the coating system also includes a disperser, which stirs and disperses the paint in the hopper. After the paint is stirred evenly, the hopper is transferred to the positioning frame.
