[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0029] Before introducing the various embodiments of the present invention, the ideal and actual situations in the coating process of the present invention will be described first. Based on this, the process of discovering the technical problem in this application will be described, as well as the objective difficulties in discovering the technical problem. Figure 1 This is a schematic diagram of a coating apparatus provided in an embodiment of the present invention, with reference to... Figure 1The coating apparatus includes multiple workstations 10, multiple workpieces 20, and multiple workpiece disks 30 for supporting the multiple workpieces 20. During the coating process, the revolution and rotation of the workpieces 20 do not occur simultaneously. The multiple workpiece disks 30 first revolve around a revolution axis 41, causing the multiple workpieces 20 they support to rotate around the revolution axis 41 (e.g., along...). Figure 1 (The rotation occurs in the direction of the middle arrow). After rotating to the next station 10, the multiple workpieces 20 stop revolving. The drive module simultaneously drives the multiple workpieces 20 to rotate around the rotation axis 42. The drive module may include, for example, a rotation motor.

[0030] Figure 2 for Figure 1 The diagram shows a partial structural schematic of the coating apparatus. To better illustrate the detection method of the origin sensor 50, its position is shown outside station 10, on the side of the workpiece disk 30. In reality, as... Figure 1 As shown, the origin sensor 50 can be located within the workstation 10 and below the workpiece disk 30. The origin sensor 50 emits a detection beam along a vertical or approximately vertical direction. The vertical direction is perpendicular to the plane of the workpiece disk 30, and the angle between the approximately vertical direction and the vertical direction is less than a preset value, that is, the approximately vertical direction is close to the vertical direction.

[0031] After the workpiece 20 rotates one or more times, the position of the workpiece 20 when the maximum light intensity detected by the origin sensor 50 is taken as the origin position of the workpiece 20.

[0032] Figure 3 This is a schematic diagram showing the workpiece disk in an ideal position according to an embodiment of the present invention. Figure 4 for Figure 3 The diagram shows the detection optical path of the origin sensor when the workpiece disk is in an ideal position. Figure 2 , Figure 3 and Figure 4 As shown, after workpiece 20 revolves to the next station 10, the workpiece disk 30 carrying workpiece 20 is located at the middle position of the corresponding station 10, that is, the distances of the left spacing L1 and the right spacing L2 are equal, and workpiece 20 is located at the middle position of workpiece disk 30 (D1 = D2). Workpiece 20 rotates around its rotation axis 42 (e.g., along...). Figure 2 When the workpiece 20 rotates (as indicated by the arrow in the middle), the via 200 on the workpiece 20 rotates along with the workpiece 20. When the via 200 is directly above the center of the origin sensor 50, and the extension direction of the via 200 is consistent with the light emission direction of the origin sensor 50, the origin sensor 50 can detect the maximum light intensity. In some embodiments, the via 200 can be a blind hole; in other embodiments, the via 200 can be a through hole.

[0033] Figure 5 A schematic view of a workpiece disc in a non-ideal position is provided for the embodiments of the present application, Figure 6 Figure 5 A schematic view of the detection light path of the origin sensor when the workpiece disc is in a non-ideal position is shown in FIG. 4, and reference is made to Figure 2 Figure 5 Figure 6 Due to machining or assembly errors, the relative positions of each workpiece disc 30 corresponding to the work station 10 and each workpiece 20 corresponding to the workpiece disc 30 are different (L1≠L2, D1≠D2). When the workpiece 20 rotates, the via 200 on the workpiece 20 rotates with the workpiece 20. The center of the workpiece 20 deviates from the center position of the origin sensor 50 and is no longer located directly above the center position of the origin sensor 50. When the extension direction of the via 200 is consistent with the light emission direction of the origin sensor 50 (for example, the vertical direction), the maximum light intensity detected by the origin sensor 50 is not the maximum. The light emission direction of the origin sensor 50 (for example, the vertical direction) does not pass through the center position of the workpiece 20. When the extension direction of the via 200 has a certain angle with the light emission direction of the origin sensor 50 (for example, Figure 6 When the extension direction of the via 200 slightly deflects), the light emitted by the origin sensor 50 reaches the via 200 and detects the maximum light intensity.

[0034] Based on the above analysis, due to part machining and assembly errors, the positions of the workpieces 20 carried in different workpiece discs 30 relative to the origin sensor 50 have deviations, and it is impossible to ensure that each workpiece 20 outputs a trigger signal at the same angle, so the process requirements cannot be met. Next, based on the above introduction, a coating method, system and medium based on a coating device according to an embodiment of the present application will be described in detail.

[0035] Embodiment one

[0036] Figure 4 A flowchart of a coating method based on a coating device according to an embodiment of the present application is shown in FIG. 5. The embodiment can be applied to a case where due to part machining and assembly errors, the positions of different workpieces relative to the origin sensor have deviations, and it is impossible to ensure that each workpiece outputs a synchronous trigger signal at the same angle. The method can be executed by a processing device in a coating system according to an embodiment of the present application. The processing device can be realized in the form of software and / or hardware. As shown in FIG. 5, the method specifically includes the following steps: Figure 4

[0037] S110, obtaining the deflection angle when the workpiece is in the origin position.

[0038] ​​​​The origin position can be a position of the workpiece 20 detected by the origin sensor 50 when the workpiece 20 is at a light intensity maximum point in the self-rotation process. The position of the workpiece 20 includes a self-rotation angle of the workpiece 20.

[0039] Exemplarily, in an ideal case, the coating material on the workpiece 20 can be located on a horizontal plane when the workpiece 20 is at a light intensity maximum point in the self-rotation process detected by the origin sensor 50 located on the work station 10. However, in an actual case, due to part processing and assembly errors, the coating material on the workpiece 20 rotates when the workpiece 20 is at a light intensity maximum point detected by the origin sensor 50 on each work station 10, and is located on a deviation plane deviating from the horizontal plane. The angle between the deviation plane and the horizontal plane is a deflection angle of the workpiece 20 at the origin position. Specifically, the deflection angle can be automatically collected by an angle detection sensor, which can be a gyroscope. A plurality of angle detection sensors can be respectively fixed on the corresponding workpieces 20, and when the workpiece 20 is self-rotated to the origin position, the angle detection sensor can transmit the deflection angle to a PLC (Programmable Logic Controller) through wireless communication technology. In an ideal case, the deflection angles of all workpieces 20 are 0°. However, in an actual case, the deflection angles of the workpieces can be different angles, which can be 0° or some angles close to 0°.

[0040] Specifically, when the workpiece 20 is self-rotated, the angle detection sensor transmits data to the PLC through wireless communication technology, and the PLC controls different workpieces 20 to perform a back-to-origin action in different work stations 10 through logic programming. It should be noted that the back-to-origin action of the workpiece 20 refers to that, after the workpiece 20 is rotated for one or more than one revolution in a self-rotation manner, the light intensity maximum value can be detected by the origin sensor 50, and after the detection is completed, the workpiece 20 is controlled to return to the position where the light intensity maximum value is detected by the origin sensor 50, i.e., the workpiece 20 is self-rotated to the origin position. At this time, the deflection angle of the workpiece at the origin position is detected by the angle detection sensor.

[0041] S120, acquiring a compensation time of the workpiece according to the deflection angle.

[0042] Specifically, the angle detection sensor transmits the deflection angle to the PLC, and the PLC saves the deflection angle in its memory and converts the collected compensation angle into a corresponding time according to the current rotation speed through algorithm processing (time = stroke / speed). The conversion relationship can satisfy C = A * 1000 / (6 * B), where the deflection angle is denoted as A, the self-rotation speed of the workpiece is denoted as B, and the compensation time is denoted as C. The compensation time conversion relationship of different self-rotation speeds is shown in Table 1.

[0043] Table 1 compensation time conversion relationship of different self-rotation speeds

[0044]

[0045]

[0046] The compensation time is calculated to obtain the time for the workpiece to rotate from the original position to the horizontal position.

[0047] S130, according to the compensation time, sending a trigger signal for controlling the discharge of the target material power supply.

[0048] Each station is provided with a corresponding target material power supply for receiving the trigger signal and discharging according to the trigger signal to start the film coating operation. Specifically, the PLC delays sending a trigger signal for controlling the discharge of the target material power supply according to the compensation time.

[0049] The deflection angle of a workpiece when it is at the original position is often not equal to the deflection angle of another workpiece when it is at the original position.

[0050] Reference Figure 1 For ease of description, four stations 10, four workpiece discs 30 and four workpieces 20 are taken as examples. The four stations 10 are respectively referred to as a first station 11, a second station 12, a third station 13 and a fourth station 14. The four workpiece discs 30 are respectively referred to as a first workpiece disc 31, a second workpiece disc 32, a third workpiece disc 33 and a fourth workpiece disc 34. The four workpieces 20 are respectively referred to as a first workpiece 21, a second workpiece 22, a third workpiece 23 and a fourth workpiece 24. When the first workpiece disc 31 is at the center position of the first station 11, due to errors in processing, assembly, etc., the second workpiece disc 32 is not at the center position of the second station 12, the third workpiece disc 33 is not at the center position of the third station 13, and the fourth workpiece disc 34 is not at the center position of the fourth station 14. Thus, after the first workpiece 21 performs the back-to-origin action, the target material power supply immediately discharges, and the deflection angle of the corresponding first workpiece 21 is 0°. After the second workpiece 22 performs the back-to-origin action, the target material power supply immediately discharges, and the deflection angle of the corresponding second workpiece 22 is not 0°. Similarly, after the third workpiece 23 performs the back-to-origin action, the target material power supply immediately discharges, and the deflection angle of the corresponding third workpiece 23 is not 0°. After the fourth workpiece 24 performs the back-to-origin action, the target material power supply immediately discharges, and the deflection angle of the corresponding fourth workpiece 24 is not 0°. This results in the situation that it is impossible to guarantee that each workpiece outputs a trigger signal at the same angle, and the target material power supply discharges according to the trigger signal.

[0051] Thus, for the second workpiece 22, the third workpiece 23 and the fourth workpiece 24 whose deflection angles are not 0°, it is necessary to continue to rotate them until their deflection angles are 0°, and then let the corresponding target material power supply discharge.

[0052] The PLC calculates the time delay of each workpiece, and then sends the trigger signal for discharging the target material power supply of the corresponding work station in time delay, so that each workpiece can output the trigger signal at the same angle.

[0053] The coating method based on the coating device provided in the embodiment of the application solves the problem that different workpieces have deviation from the position of the original point sensor due to actual part machining and assembly errors, and cannot output the synchronous trigger signal at the same angle, and further ensures that each workpiece can output the synchronous trigger signal at the same angle, thereby meeting the process requirement.

[0054] Embodiment Two

[0055] Figure 8 A flowchart of the coating method based on the coating device in the embodiment Two of the application is shown in Figure 8 The method comprises the following steps:

[0056] S210, one of the plurality of work stations is determined as a reference work station; the position of the workpiece disc in the reference work station is adjusted, so that the workpiece disc is at the center position of the reference work station.

[0057] The reference work station can be the adjusted position of the workpiece disc. Specifically, due to factors such as revolution error, part machining and assembly error, the workpiece disc deviates from the center position after stopping revolution, and further affects the film forming process, resulting in low product quality. Therefore, in the embodiment of the application, one of the plurality of work stations is determined as a reference work station, and after the workpiece revolves to the reference work station and stops, the workpiece disc carrying the workpiece is adjusted to the position of the reference work station, so that the workpiece disc is located at the center position of the reference work station, thereby avoiding affecting the film forming process and improving the product quality.

[0058] In addition, it should be noted that the reference work station can be one, and each workpiece disc revolves to the reference work station in turn for reference. Only after the last workpiece disc is referenced and each workpiece obtains the compensation time by self-rotation and outputs the trigger signal at the same angle, the next workpiece disc can revolve to the reference work station for reference.

[0059] S220, the driving module is controlled to rotate, and the deflection angle of each workpiece at its corresponding original position is obtained in turn.

[0060] Specifically, since the driving module is used to drive each workpiece to self-rotate at the same time, in actual situations, each workpiece cannot achieve the same angle at the same time, that is, the deflection angles of each workpiece are different.

[0061] Exemplarily, reference is made to Figure 1, the deflection angle of the fourth workpiece 24 at the first work station 11, the deflection angle of the first workpiece 21 at the second work station 12, the deflection angle of the second workpiece 22 at the third work station 13, and the deflection angle of the third workpiece 23 at the fourth work station 14; the deflection angle of the third workpiece 23 at the first work station 11, the deflection angle of the fourth workpiece 24 at the second work station 12, the deflection angle of the first workpiece 21 at the third work station 13, and the deflection angle of the second workpiece 22 at the fourth work station 14; and the deflection angle of the second workpiece 22 at the first work station 11, the deflection angle of the third workpiece 23 at the second work station 12, the deflection angle of the fourth workpiece 24 at the third work station 13, and the deflection angle of the first workpiece 21 at the fourth work station 14.

[0062] S230, obtaining the compensation time of the workpiece according to the deflection angle.

[0063] S240, sending a trigger signal for controlling the discharge of the target material power supply according to the compensation time, and obtaining the deflection angle of the workpiece when the trigger signal is sent.

[0064] Exemplarily, the comparison of the angles of different workpieces before and after compensation at the same work station is shown in Table 2.

[0065] Table 2 Comparison of angles of different workpieces before and after compensation at the same work station

[0066] Workpiece Deflection angle before compensation Deflection angle after compensation 1 0.72 0 2 2.78 0.07 3 1.17 0.13 4 2.78 0.07

[0067] Specifically, in actual measurement, due to the existence of angle measurement error and PLC operation scanning period restriction, the deflection angle after compensation is not 0°, but it has met the 0.5° error range allowed by the device process, and the effect of outputting the synchronous trigger signal at the same angle for each workpiece is achieved.

[0068] In the embodiment of the application, the position of the workpiece disc is adjusted by the reference work station, and the deflection angle of each workpiece at the corresponding original position is obtained by rotating the control driving module, the compensation time of each workpiece is obtained according to each deflection angle, and then the trigger signal for controlling the discharge of the target material power supply of each work station is sent through the total delay time of each workpiece, thereby solving the problem that the deviation exists between different workpieces relative to the original position of the sensor due to the actual part machining and assembly error, and the synchronous trigger signal cannot be output at the same angle, thereby ensuring that each workpiece can output the synchronous trigger signal at the same angle and meeting the process requirement.
