[0052] Example 1

[0053] Figure 1 It is a schematic structural diagram of the automatic dipping device 100 from a first viewing angle in Example 1 of the present invention; Figure 2 It is a schematic structural diagram of the automatic dipping device 100 from a second viewing angle in Example 1 of the present invention; Figure 3 This is a third perspective structural diagram of the automatic dipping device 100 in Example 1 of the present invention. Figures 1 to 3, an automatic dipping device 100 provided in this embodiment includes a turntable 180, a processing mechanism 110 arranged below the turntable 180, a driving mechanism for driving the turntable 180 and the processing mechanism 110 to rotate relative to each other, approach or move away, and a control system 105. The turntable 180 is provided with a plurality of workpiece picking mechanisms 181 for picking up workpieces, and the plurality of workpiece picking mechanisms 181 are preferably arranged in a ring-shaped and uniform interval on the turntable 180. The processing mechanism 110 has a plurality of processing positions corresponding to the number and position of the workpiece picking mechanisms 181, and the number of the processing positions is equal to the number of the plurality of workpiece picking mechanisms and is also preferably arranged in a ring-shaped and spaced arrangement. When the turntable 180 rotates relative to the processing mechanism 110, the workpiece picking mechanism 181 can move the workpiece it picks up to the next station for the next processing. There is a loading and unloading station and at least one dipping station in the processing position, and the dipping station is provided with a dipping device for dipping the workpiece.

[0054] A workpiece picking mechanism 181 on the turntable 180 picks up the workpiece to be processed above the loading and unloading station, and other workpiece picking mechanisms 181 on the turntable 180 can pick up the workpieces that have completed the corresponding process at other processing positions. After the turntable 180 and the processing mechanism 110 rotate relative to each other, all the workpieces picked up on the turntable 180 can enter the next processing position, and the workpieces processed at the most downstream processing position are transferred to the loading and unloading station and can be removed by the staff. The control system 105 can control the picking or releasing of the workpiece picking mechanism 181, as well as the direction and frequency of the relative movement between the processing mechanism 110 and the turntable 180. The control system 105 can be a single-chip microcomputer, a PLC, a computer, etc.

[0055] In this embodiment, the turntable 180 is circular, and the axis of the center is the location of the rotation axis. The driving mechanism is connected to the turntable 180 in a transmission manner to drive the turntable 180 to rotate. In order to ensure the stability of the equipment, the turntable 180 can be arranged horizontally, and a plurality of workpiece picking mechanisms 181 are arranged on its lower surface. The processing mechanism 110 is arranged below the turntable 180, and each processing position of the processing mechanism 110 is respectively located directly below each workpiece picking mechanism 181. When the turntable 180 is driven to rise by the driving mechanism, the workpiece can be taken out from the processing device of each processing position; when the turntable 180 is driven to lower by the driving mechanism, the workpiece can be placed in each processing device for processing.

[0056] In this embodiment, five workpiece picking mechanisms 181 are arranged on the lower side of the turntable 180; and the processing mechanism 110 is correspondingly provided with five processing positions, namely, a loading and unloading position, a preheating position, a dipping position, a drying position, and an air cooling position. Different processing devices are provided corresponding to each position, and the workpieces can be processed in sequence. It can be understood that in this embodiment, the circumferential angle between adjacent workpiece picking mechanisms 181 is 72°. In other embodiments, when the number of processing positions and the number of workpiece picking mechanisms 181 arranged on the turntable 180 change, the angle between each workpiece picking mechanism 181 should be adjusted so that each workpiece picking mechanism 181 is evenly spaced in the circumferential direction.

[0057] The driving mechanism includes a rotating mechanism 170 and a lifting mechanism 175 . In this embodiment, the rotating mechanism 170 is used to drive the turntable 180 to rotate relative to the processing mechanism 110 ; the lifting mechanism 175 is used to drive the turntable 180 to move closer to or away from the processing mechanism 110 .

[0058] Specifically, the rotating mechanism 170 includes a first driving part 172, a base 174 and a turntable 173. The turntable 173 is disc-shaped, which is horizontally arranged on the base 174 and can rotate horizontally relative to the base 174 around its own axis. The first driving part 172 is a cylinder, and the free end of its piston rod is rotatably connected to the eccentric position of the turntable 173. When the piston rod is extended or retracted, it can drive the turntable 173 to reciprocate. The lifting mechanism 175 is arranged on the turntable 173, which includes a second driving part 176. The second driving part 176 is a cylinder and is electrically connected to the control system 105. The piston rod of the second driving part 176 is connected to the bottom of the turntable 180 and can drive the turntable 180 to move up and down.

[0059] In this embodiment, the first driving unit 172 is electrically connected to the control system 105, and the first driving unit 172 can drive the turntable 173 to reciprocate 72° under the control of the control system 105. In this way, the workpiece picking mechanism 181 provided on the turntable 180 can pick up the workpiece and move it between two adjacent processing positions, that is, the workpiece processed at one processing position can be moved to the next processing position and then turned back to pick up the next workpiece.

[0060] It should be understood that in other embodiments of the present invention, the first driving part 172 and the second driving part 176 may also be a cylinder, a linear motor, etc. The implementation of the rotating mechanism 170 is not limited to Figure 1 In the form of, for example, a motor can be directly connected to the bottom center of the turntable 173 to drive the turntable 173 to rotate; in order to accurately control the rotation angle, the motor can be a stepper motor. In this case, the turntable 173 can also be rotated 72° in one direction to make the workpiece pass through each processing position in turn, without having to rotate back and forth 72°.

Figures 4 to 8 In this embodiment, the workpiece picking mechanism 181 is preferably a suction cup electromagnetic magnetic disk, which is arranged on the lower surface of the turntable 180. The suction cup electromagnetic magnetic disk has multiple magnetic suction parts 1811. The magnetic suction parts 1811 are adsorbed or desorbed by electrically connecting or disconnecting with a power supply (not shown). The workpiece picking mechanism 181 picks up the workpiece through the material tray 182. The material tray 182 includes a clamping disk 1822, a clamping disk 1821 and a clamp. The clamp is arranged on the lower end surface of the clamping disk 1822 for clamping and fixing the workpiece. Preferably, the clamp can be a spring clamp 1823 or other device that can be used to clamp an object. The clamping disk 1821 is fixedly connected to the upper end surface of the clamping disk 1822, and the clamping disk 1821 is made of metal that can be magnetically adsorbed, such as cast iron. The workpiece picking mechanism 181 picks up the workpiece by adsorbing the material tray 182 by the suction cup electromagnetic magnetic disk. A plurality of buffer springs 1812 are arranged in a circular array on the suction cup electromagnetic disk. When the material tray 182 is sucked up, it will first contact the buffer springs 1812 for buffering, thereby preventing the material tray 182 from causing a strong rigid impact on the suction cup electromagnetic disk.

[0062] Fig. 9 This is a schematic diagram of the cooperation between the material tray 182 and the workpiece picking mechanism 181 in another embodiment of the present invention. Fig. 9 In this embodiment, the workpiece picking mechanism 181 clamps the material tray 182 by a clamping mechanism, rather than by magnetic adsorption as described above. Fig. 9 In the embodiment of the invention, the workpiece picking mechanism 181 is a pneumatic clamping mechanism, which preferably includes clamping parts 1824 arranged along the circumferential direction, and the number of clamping parts 1824 can be selected as needed, such as 2, 3 or more than 3. The clamping parts 1824 are provided with grooves for the edges of the clamping disc 1821 to be embedded in, and the plurality of clamping parts 1824 move radially inward, and the clamping disc 1821 is embedded in the grooves of the clamping parts 1824 to complete the clamping action of the material tray 182.

[0063] Please continue to refer to Figures 1 to 8In Example 1, the loading and unloading station, preheating station, dipping station, drying station and air cooling station of the processing mechanism 110 are arranged in a circle from upstream to downstream. The loading and unloading station, preheating station, dipping station, drying station and air cooling station are respectively provided with a loading and unloading barrel 120, a preheating barrel 125, a coating barrel 130, a drying barrel 140 and an air cooling barrel 145 (for the sake of simplicity, Figure 1 , Figure 2 Only two barrels are shown), and the opening of each barrel faces the turntable 180. A positioning structure 115 is provided at the opening of each barrel, so that when the workpiece enters the barrel, the lower end surface of the fixture plate 1822 abuts against the upper end surface of the corresponding station barrel. The positioning structure 115 can position the material plate 182, firstly to prevent the workpiece from falling to the bottom of the barrel, and secondly to position the workpiece. In this embodiment, the positioning structure 115 can be a plurality of positioning blocks arranged around the opening.

[0064] The processing mechanism 110 may include an air heating device 127, which is connected to the preheating barrel 125 through a hot air pipeline (not shown), and the air heating device 127 is configured to deliver heated air to the preheating barrel 125, so that the hot air can be used to preheat the workpiece in the preheating barrel 125, so that the workpiece is convenient for subsequent dip coating. In other embodiments of the present invention, a heating device can also be provided in the preheating barrel 125, and the heating device can be an electric heating wire, so that the workpiece is preheated directly by electric heating.

[0065] The processing device on the dipping station includes a paint bucket 130 and a stirring device arranged on the paint bucket 130. The stirring device includes a third driving part 132 and a stirring rod 134. The third driving part 132 is preferably a motor. The motor is connected to one end of the stirring rod 134 to drive the stirring rod 134 to rotate along the axis. The free end of the stirring rod 134 extends into the paint bucket 130. The free end of the stirring rod 134 is provided with a blade to enhance the stirring ability. The motor drives the blade to automatically stir the paint to prevent the paint from settling.

[0066] In order to avoid the coating on the workpiece after dipping and accumulation, the automatic dipping equipment 100 also includes a flipping mechanism 150, and one of the workpiece picking mechanisms 181 on the turntable 180 is rotatably connected to the turntable 180, and the connection method can be hinged. The flipping mechanism 150 includes a fourth driving part 152, and the fourth driving part 152 is preferably a cylinder. The cylinder is fixed on the turntable 180, and its power output end is connected to the workpiece picking mechanism 181 that can rotate relative to the turntable 180 through a connecting rod. The workpiece picking mechanism 181 is a workpiece picking mechanism 181 that reciprocates between the dipping station and the preheating station. After the workpiece is dipped, the material tray 182 clamping mechanism above the dipping station clamps the material tray 182 on the dipping station barrel and rises to a predetermined position. The cylinder drives the workpiece picking mechanism 181 together with the material tray 182 and the workpiece to flip positive and negative 90 degrees in the vertical direction, which can effectively avoid the coating from hanging upside down and accumulating. The fourth driving unit 152 is electrically connected to the control system 105. In other embodiments of the present invention, if the motion mode of the turntable 173 is driven by the first driving unit 172 to rotate 72° in sequence (rather than reciprocating 72°), each workpiece picking mechanism 181 is required to be flipped by the corresponding flipping mechanism 150.

[0067] In this embodiment, the automatic dipping equipment 100 further includes a translation material receiving device 160, which is used to pick up the turned workpiece and remove it from the workpiece picking mechanism 181, and to send the workpiece to the workpiece picking mechanism 181. Specifically, the translation material receiving device 160 includes a fifth driving part 162, which is preferably a cylinder, which is transmission-connected to a receiving tray 164 through a connecting rod, and the cylinder drives the receiving tray 164 to enter or leave the position directly below the workpiece picking mechanism 181 above the coating bucket 130. Specifically, after the workpiece is dipped and flipped, the translational material receiving device 160 executes the material receiving procedure, and the cylinder drives the material receiving tray to enter the position directly below the workpiece picking mechanism 181 above the coating bucket 130. The workpiece picking mechanism 181 releases the material tray 182, and the material tray 182 is supported on the material receiving tray. The flipped material tray 182 can be further moved to one side to wait for the workpieces in the preheating and other workstations to complete the corresponding process; the translational material receiving device 160 can also execute the feeding procedure. When all processes are completed, the above-mentioned material tray 182 can be moved to the position directly below the workpiece picking mechanism 181 above the dipping bucket, and the workpiece picking mechanism 181 picks up the material tray 182 and waits for the next process.

[0068] It should be understood that in this embodiment, the movable end of the cylinder as the fifth driving part 162 can be provided with a clamp to clamp the material tray 182 that is already in the flipped state, and the clamp can be a pneumatic finger or other clamp whose clamping and releasing actions can be controlled by the control system 105. In other embodiments, the fifth driving part 162 can also be an oil cylinder, a linear motor, etc.

[0069] In addition, in order to prevent the workpiece from falling to the bottom of the paint bucket 130 when being dipped in the paint bucket 130, a material frame 136 with a mesh structure is also provided in the paint bucket 130, and the material frame 136 can hold the workpiece when the workpiece falls.

[0070] The drying station is used to dry the workpiece after dipping, speed up the drying speed of the coating, and ensure that the coating can better adhere to the surface of the workpiece. A heating device is provided in the drying drum. In this embodiment, the heating device can be an air heating device 127, which heats the air by using the air heating device 127, and then blows hot air into the drying drum through the hot air pipeline for drying. In other embodiments of the present invention, the heating device can also be an electric heating wire, which directly dries the workpiece by electric heating.

[0071] The air cooling station is used to blow air to cool the workpiece after dipping, so the processing mechanism 110 also includes an air cooling fan 147, and the air cooling fan 147 is connected to the air cooling barrel 145 through a pipeline (not shown in the figure). The air cooling fan 147 can blow cold air into the air cooling barrel 145 to cool the workpiece after drying, so that the workpiece can be cooled quickly, the waiting time can be shortened, and the processing efficiency can be accelerated.

[0072] In this embodiment, the automatic dipping equipment 100 may further include a protective cover 190, which is a rectangular box. The processing mechanism 110, the turntable 180, the control system 105, the driving mechanism, etc. are all arranged in the protective cover 190. The protective cover 190 is provided with a material port near the loading and unloading barrel 120 (see Figure 3 The air cooling fan 147 and the translation material receiving device 160 are both arranged on the inner wall surface of the protective cover 190. The air source of the air cooling fan 147 and the air heating device 127 can come from the outside of the protective cover 190 and be introduced into the air cooling fan 147 and the air heating device 127 through pipelines.

[0073] Example 2

[0074] Fig.10 This is a schematic diagram of the structure of the automatic dipping device 100 in Example 2 of the present invention. Fig.10 , and combined with the drawings of Example 1, this embodiment provides an automatic dipping device 200, which is substantially the same as the automatic dipping device 100 of Example 1. The difference between the two is that the driving mechanism of the automatic dipping device 200 of this embodiment is used to drive the processing mechanism 110 to rotate and lift.

[0075] In this embodiment, the turntable 173 is preferably annular, and the loading and unloading barrel 120, the preheating barrel 125, the paint barrel 130, the drying barrel 140 and the air cooling barrel 145 are circumferentially arranged on the turntable 173, and the turntable 180 is fixed by a bracket. Therefore, in this embodiment, the rotating mechanism 170 realizes the reciprocating rotation of the processing mechanism 110 relative to the turntable 180 by rotating the turntable 173 by 72 degrees. In this embodiment, the lifting mechanism 175 preferably includes five second driving parts 176, which are respectively arranged at the bottom of the loading and unloading barrel 120, the preheating barrel 125, the paint barrel 130, the drying barrel 140 and the air cooling barrel 145 to lift each barrel.

[0076] Example 3

[0077] This embodiment provides a dip coating process, which uses the automatic dip coating equipment 100 in embodiment 1 to dip coat the workpiece. The steps include:

[0078] S1. Fix the workpiece on a material tray 182 and position the material tray 182 on the loading and unloading barrel 120.

[0079] When the number of executions of step S1 is N1 ≥ 6, the tray 182 that has completed the air cooling process on the loading and unloading barrel 120 needs to be unloaded together with the workpiece;

[0080] When step S1 is executed for a number of times N1≤5, no workpiece has completed the air cooling process, that is, no unloading operation is required.

[0081] S2, the lifting mechanism 175 drives the turntable 180 and the workpiece picking mechanism 181 to descend to a predetermined position, and the workpiece picking mechanism 181 picks up the material trays 182 on all workstations and lifts them to a predetermined height;

[0082] When executing step S2, there is no material tray 182 on the paint bucket 130 (because the dipping process takes a short time, the material tray 182 at this position has been lifted in advance). When step S2 is executed for a number of times N2≤1, there is no material tray 182 at the four stations of preheating, dipping, drying, and air cooling.

[0083] S3, the translation receiving device 160 executes the feeding procedure, driving the material tray 182 to the position directly below the workpiece picking mechanism 181 above the dipping station, and the workpiece picking mechanism 181 picks up the material tray 182;

[0084] The material tray 182 in this step refers to the material tray 182 moved to one side by the translation receiving device 160 after the dip coating is completed. When the number of executions of step S3 N3≤2, no workpiece has completed the dip coating process, and when the translation receiving device 160 executes the feeding procedure, there is no material tray 182 on the translation receiving device 160.

[0085] S4, the rotating mechanism 170 drives the rotating disk 180 forward ( Figure 3 The material tray 182 is rotated 72° in the counterclockwise direction in the drawing, thereby driving the material tray 182 to automatically enter the position of the next workstation. The material tray 182 lifting mechanism 175 drives the material tray 182 to descend to a predetermined position and releases the material tray 182; the material tray 182 refers to the material tray 182 on all processing positions.

[0086] Wait for all workpieces to enter the predetermined station and complete the corresponding process at the corresponding station. In this embodiment, among the four steps of preheating-dipping-drying-air cooling, the three steps of preheating, drying and air cooling take a long time, which is 60s to 100s, and the preheating temperature is preferably 80 to 100 degrees Celsius. The dipping process takes a shorter time and will be completed in advance. The dipping time is 5s to 10s, and the thickness of the coating on the workpiece is preferably 0.08mm to 0.12mm.

[0087] After the workpiece at the dipping station is dipped and the processing at other stations is not completed, the corresponding workpiece picking mechanism 181 will pick up the material tray 182 on the paint bucket 130 (the material trays 182 at other stations will not be picked up), and the lifting mechanism 175 drives the material tray 182 to rise to a predetermined height.

[0088] S5. After the workpiece that has just completed the dipping process is lifted, the turning mechanism 150 drives the workpiece picking mechanism 181 to turn forward 90° and wait for 5s to 10s before turning backward 90° to avoid coating dripping and accumulation.

[0089] S6, the translation receiving device 160 executes the receiving procedure, and moves the dip-coated and turned-over material tray 182 together with the workpiece to one side to enter the waiting process. The material tray 182 in this step refers to the turned-over material tray 182 above the dip-coating station.

[0090] When the step S6 is executed for a number of times N6≤1, no workpiece has completed the dipping and coating, and when the translational material receiving device 160 executes the material receiving procedure, the translational material receiving device 160 will not receive the material tray 182 .

[0091] S7, the rotating mechanism 170 drives the rotating disk 180 in the reverse direction ( Figure 3 clockwise in the figure) is rotated 72°.

[0092] S8. Continue to execute step S1.

[0093] The above 8 steps are executed cyclically to gradually complete the loading and unloading - preheating - dipping - drying - air cooling - loading and unloading processes of each workpiece. (After step S1 is executed more than 5 times, each station will have a material tray 182)

[0094] In summary, the automatic dipping equipment (100, 200) of the embodiment of the present invention comprises a turntable 180, a processing mechanism 110 disposed below the turntable 180, a driving mechanism for driving the turntable 180 and the processing mechanism 110 to rotate relative to each other, approach or move away from each other, and a control system 105. The turntable 180 is provided with a plurality of workpiece picking mechanisms 181 for picking up workpieces, and the plurality of workpiece picking mechanisms 181 are preferably arranged in a ring-shaped and uniformly spaced arrangement on the turntable 180. The processing mechanism 110 has a plurality of processing positions corresponding to the number and position of the workpiece picking mechanisms 181. The processing positions include a loading and unloading station and at least one dipping station, and the dipping station is provided with a dipping device for dipping the workpiece. A workpiece picking mechanism 181 on the turntable picks up the workpiece to be processed at the loading and unloading station. After the turntable 180 and the processing mechanism 110 rotate relative to each other, all the workpieces picked up on the turntable 180 can enter the next processing position, and the workpiece processed at the most downstream processing position is transferred to the loading and unloading station and can be removed by the staff. The control system 105 can control the picking or releasing of the workpiece picking mechanism 181, as well as the direction and frequency of the relative movement between the processing mechanism 110 and the turntable 180. In this way, the entire automatic dip coating process can simultaneously perform dip coating processing on multiple workpieces in different processes, and each workpiece and each process does not interfere with each other, with high processing efficiency, stable process and small error.

[0095] The dipping process of the embodiment of the present invention uses the above-mentioned automatic dipping equipment (100, 200) to process the workpiece, with high processing efficiency and stable process.
