The feeding device 5 is used to transport the workpiece 6 to the resin spraying station 1, the resin curing and removal station 2, the electrolysis station 3 and the cleaning station 4 in sequence.

[0039] Reference Figure 1 As shown, in this embodiment, the feeding device 5 includes a vertical transfer mechanism and a lateral transfer mechanism. The vertical transfer mechanism is used to drive the workpiece 6 to move in the vertical direction. The lateral transfer mechanism is arranged on the vertical transfer mechanism and is used to drive the workpiece 6 to move in the horizontal direction.

[0041] The vertical transport mechanism includes a plurality of vertical guide rails 53 which are arranged at equal intervals on the same side of the transverse guide rail 51.

[0043] Reference Figure 1 and Figure 7As shown, in this embodiment, the resin spraying device includes a spraying tank 11, a cleaning nozzle 12, a sprayer 13 and a dryer 14. The cleaning nozzle 12, the sprayer 13 and the dryer 14 are respectively arranged on the three inner walls of the spraying tank 11. The cleaning nozzle 13, the dryer 14 and the sprayer 13 can be controlled by a control unit to clean, dry and spray the workpiece 6 with resin in sequence. After the workpiece 6 is cleaned and dried, the original surface is exposed to the outside world, and then the resin coating can be sprayed on the surface of the workpiece 6 by the sprayer 13 to form a protective layer.

[0044] Reference Figure 1 to Figure 6 As shown, in this embodiment, the resin curing and removal station 2 is provided with a base 20, and the curing device and the scraping device are both provided on the base 20. Specifically, a workbench 21 is also provided on the base 20, and the workbench 21 is provided in the middle of the scraping device, and the curing device is provided in front of the workbench 21. It can be understood that the curing device can also be provided on both sides of the workbench 21, and the present invention does not make specific limitations. The resin curing and removal station 2 adopts the method of building blocks to realize the modularization of the curing device and the removal device.

[0045] In this embodiment, the curing device includes a bracket 22 and a UV light generator 23 fixed on the bracket 22, and the bracket 22 is arranged on the base 20. The UV light generator 23 is aligned with the center of the workbench 21 so that the UV light emitted by the UV light generator 23 can be irradiated onto the workpiece 6 for curing the protective layer. By using the curing device, the protective layer resin can be accurately cured, which not only saves labor costs, but also improves the curing quality and ensures the processing quality of the workpiece 6.

[0046] In this embodiment, the scraping device comprises a scraping belt 24 adapted to the width of the protective layer to be scraped off and a driving device. The scraping belt 24 is driven by the driving device to run to scrape off the protective layer on the workpiece 6.

[0047] Specifically, the driving device includes a slide rail 25 symmetrically arranged on both sides of the workbench 21, and a slider 26 is respectively arranged on the slide rail 25. The driving device also includes a motor 27, preferably, the motor 27 is a stepping motor. The motor 27 is mounted on the slider 26 on one side of the workbench 21. A first column 28 rotatably connected to the motor 27 is also arranged on the motor 27. A second column 29 is arranged on the slider 26 on the side of the workbench 21 away from the first column 28. A scraping belt 24 is sleeved on the first column 28 and the second column 29, and the scraping belt 24 can rotate around the first column 28 and the second column 29 under the drive of the first column 28, and is used to scrape off the protective layer on the workpiece 6. The slider 26 of the present invention can realize the forward and backward movement of the scraping belt 24, and is used to adjust the position of the scraping belt 24 and the workpiece 6. By using a scraping belt 24 with a certain bandwidth to scrape off the protective layer, the efficiency is extremely high.

[0048] In this embodiment, a positioning device is also configured in the middle of the workbench 21 for positioning the workpiece. The positioning device includes a pressure sensor 7, and the pressure sensor 7 is electrically connected to the control unit. Preferably, the resolution of the pressure sensor 7 is 0.1g. The center point of the pressure sensor 7 is located on the Z axis of the workbench, and can sensitively and quickly sense pressure changes.

[0049] In a preferred embodiment, the positioning device further comprises an alarm. When the pressure value detected by the pressure sensor 7 is greater than a set value, the alarm sounds an alarm. Preferably, the set value is 2 to 5 mN.

[0050] When the first slider 52 drives the workpiece 6 to slide to the resin curing and removal station 2, driven by the second slider 54, the apex of the workpiece 6 continuously approaches the pressure sensor 7 and squeezes the contact surface of the pressure sensor 7 to deform the contact surface. When the indication of the pressure sensor 7 is between 2 and 5 mN, it is considered that the apex of the workpiece 6 coincides with the Z-axis origin of the workbench 21. If the indication of the pressure sensor 7 is greater than 5 mN, the alarm will sound an overtravel alarm, and the fixture 55 will return to its original position and re-calibrate the tool.

[0051] After the origin alignment is successful, the protective layer of the workpiece 6 is first cured, and then the protective layer of the part to be electrolyzed is scraped off. First, the second slider 54 moves the workpiece 6 upward until it reaches the horizontal position of the light ray generated by the ultraviolet light generator 23, and then the workpiece 6 slowly moves downward, and the resin on the segmented circumference of the workpiece is cured under the irradiation of ultraviolet light. After the resin is cured, the workpiece 6 is driven by the second slider 54 to descend until the protective layer to be scraped off is at the same level as the scraping belt 24. At this time, under the action of the motor 27, the scraping belt 24 rotates around the first column 28 and the second column 29, and the scraping belt 24 is driven by the slider 26 to approach the workpiece 6 and contact the surface of the protective layer on the workpiece 6. Since the scraping belt 24 has a rough surface, the protective layer is scraped off under the action of the rotating scraping belt 24. After completing the curing and scraping operations of the protective layer, the workpiece 6 returns to its original position and waits to enter the electrolysis station 3. It should be noted that if the workpiece 6 is processed for the first time and there is no cured protective layer on the surface of the workpiece 6, the workpiece 6 can directly enter the next station after UV curing the part that needs to be protected without scraping off the protective layer.

[0052] Reference Figure 1 As shown, in this embodiment, the electrolysis device 3 includes an electrolytic cell 31, an electrolyte 32, a positive electrode rod and a negative electrode rod, and the electrolyte 32 is placed in the electrolytic cell 31. A positive electrode rod is installed on one side of the electrolytic cell 31, and a negative electrode rod is installed on the other side. When the workpiece enters the electrolysis station 3, under the action of the electrolyte 32, the positive electrode rod and the negative electrode rod, the anions of oxygen react with aluminum to form an oxide film on the surface of the workpiece.

[0053] Reference Figure 1 and Figure 8 As shown, in this embodiment, the cleaning device 4 includes a cleaning tank 41, a cleaning nozzle 42 and a dryer 43. The cleaning nozzle 42 is installed on the inner side wall of one side of the cleaning tank 41, and the dryer 43 is installed on the inner side wall of the other side. When the workpiece 6 enters the cleaning station 4, the workpiece 6 can be cleaned. First, the workpiece 6 is sprayed with water through the cleaning nozzle 42, and finally the workpiece 6 is dried by the dryer 43.

[0054] In order to facilitate the understanding of the present invention, the workflow of the automatic production line of the segmented anodizing process of the present invention is described in detail below.

[0055] S1, resin spraying: first clamp the workpiece 6 on the fixture 55. Then the control unit controls the first drive group to drive the first slider 52 to move, and drives the workpiece 6 to move horizontally to the resin spraying station 1. At this time, the workpiece 6 adjusts its height through the second slider 54 under the control of the control unit and rotates at a speed of 500r / min. At the resin spraying station 1, the cleaning nozzle 12 first sprays water to clean the workpiece 6, then uses the dryer 14 to dry it, and finally the sprayer 13 evenly applies the resin coating on the surface of the workpiece 6. After the spraying is completed, the workpiece 6 rises driven by the second slider 54, and is driven by the first slider 52 to enter the resin curing and removal station 2 along the transverse guide rail 51.

[0056] S2, resin curing and removal: The first slider 52 drives the workpiece 6 to slide to the resin curing and removal station 2, and the workpiece rotates at a speed of 500r / min. Then, driven by the second slider 54, the apex of the workpiece 6 continuously approaches the pressure sensor 7 and squeezes the contact surface of the pressure sensor 7 to deform the contact surface. When the indication of the pressure sensor 7 is between 2 and 5mN, it is considered that the apex of the workpiece 6 coincides with the Z-axis origin of the workbench 21. If the indication of the pressure sensor 7 is greater than 5mN, the alarm will sound an overtravel alarm, and the fixture 55 will return to its original position and re-calibrate the tool.

[0057] After the origin alignment is successful, the second slider 54 moves the workpiece 6 upward until it reaches the horizontal position of the light beam generated by the ultraviolet light generator 23, and then the workpiece 6 slowly moves downward, and the resin on the segmented circumference of the workpiece 6 is cured under the irradiation of ultraviolet light. After the resin is cured, the workpiece 6 is driven by the second slider 54 to descend until the protective layer to be scraped off is at the same level as the scraping belt 24. At this time, under the action of the motor 27, the scraping belt 24 rotates around the first column 28 and the second column 29, and the scraping belt 24 is driven by the slider 26 to approach the direction of the workpiece 6 and contact the surface of the protective layer on the workpiece 6. Since the workpiece 6 is in a state of continuous rotation, the protective layer to be scraped off on the workpiece 6 is scraped off under the action of the scraping belt 24, and the protective layer curing and scraping operations are completed, and the workpiece 6 returns to its original position to wait for entering the electrolysis station 3.

[0058] S3, workpiece electrolysis: When the workpiece 6 enters the electrolysis station 3, under the action of the electrolyte 32, the positive electrode rod and the negative electrode rod, the oxygen anions react with the aluminum to form an oxide film on the surface of the workpiece 6, completing the electrolysis of the workpiece 6 and waiting to enter the cleaning station 4.

[0059] S4, workpiece cleaning: The workpiece 6 is driven by the feeding device 5 to enter the cleaning station 4 for cleaning. The workpiece 6 is first sprayed with water through the cleaning nozzle 42, and finally the workpiece 6 is dried by the dryer 43. At this point, the production and processing process of a workpiece 6 is completed.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
