Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to a polishing method of a multi-station disc polishing machine and the multi-station disc polishing machine. Background Art

[0002] The multi-station disc polishing machine is an automated equipment used for metal surface polishing. It achieves high-speed grinding and polishing of the workpiece surface through a rotating disc.

[0003] The Chinese patent with publication number CN118664483A discloses a multi-station disc polishing machine, which can realize the clamping and positioning or loosening of the workpiece through the clamping mechanism, and the polishing mechanism arranged on the base completes the polishing process of the workpiece clamped by the clamping mechanism, thereby realizing the flexible clamping and polishing process of such workpieces. However, the applicant found that it still has many problems and defects, which are mainly reflected in:

[0004] 1. Each station is generally used for 360° polishing, and its function is relatively single, which cannot meet the requirements of 360° polishing and single-side designated surface grinding at the same time.

[0005] 2. In actual processing, after normal use for a period of time, there is no problem with polishing quality control, but after long-term use, the small turntable will be offset when it changes from the continuous power rotation state to the fixed position state, thus affecting the polishing accuracy. Specifically, there are two states of use of the small turntable, one is the continuous power rotation state, and the other is the fixed position state. In the continuous power rotation state, the small turntable rotates all the time when the polishing machine is polishing, that is, the workpiece is polished 360°. At this time, the state of the small turntable is positioned as the continuous power rotation state. In the fixed position state, the small turntable only chooses to stop at a fixed angle, and the polishing machine only polishes and grinds one surface of the workpiece when polishing. At this time, the state of the small turntable is positioned as the fixed position state. The reason for the continuous power rotation state or the fixed position state is that 360° grinding is required when the current polishing channel is polished, but when the disc turns to the next channel for polishing, only one surface needs to be polished. Therefore, the small turntable will have a switch from a continuous powered rotation state to a positioned fixed state, or from a positioned fixed state to a continuous powered rotation state. After a long period of switching, the motor controlling their state transitions will be misaligned. The misalignment is reflected in, for example, when the continuous powered rotation state is converted to the positioned fixed state, the positioned fixed state is polished by rotating a certain angle. When it is misaligned, this angle is not accurate, so the polishing and grinding will inevitably deviate.

[0006] 3. When polishing, it is necessary to ensure the consistency and uniformity of polishing. The traditional approach is to install a pressure sensor. However, in a multi-station disc polishing machine with a Chinese patent publication number of CN118664483A, since the large turntable and the small turntable need to rotate, it is not appropriate to install a pressure sensor.

[0007] Therefore, there is an urgent need to provide a polishing method and a polishing machine for a multi-station disc polishing machine, in order to improve or even solve at least one of the above problems. Summary of the invention

[0067] refer to Figure 1-3 , the embodiment of the present application provides a polishing method of a multi-station disc polishing machine, which comprises:

[0068] Step 1, fix the workpiece on the small turntable 400 through the clamping mechanism 500, the small turntable 400 has a continuous power rotation state of rotating around the central axis of the small turntable 400, rotates to a predetermined angle and stops driving the workpiece to rotate around the central axis of the small turntable 400 in a positioned fixed state;

[0069] Step 2: The large turntable 200 drives the small turntable 400 equipped with the workpiece to revolve around the central axis of the large turntable 200, so that the workpiece passes through a plurality of workstations in sequence, wherein the plurality of workstations include a first workstation and a second workstation;

[0070] Step 3, at the first station, the workpiece is driven to rotate around the central axis of the small turntable 400 by the small turntable 400 to maintain a continuous power rotation state, and the workpiece is polished 360° by the polishing mechanism corresponding to the first station;

[0071] Step 4: At the second station, the small turntable 400 stops driving the workpiece to rotate around the central axis of the small turntable 400 to maintain a fixed position, and the designated surface of the workpiece is polished by the polishing mechanism corresponding to the second station.

[0072] In the embodiment of the present application, the small turntable 400 has a continuous powered rotation state of rotating around the central axis of the small turntable 400, and a positioned fixed state of rotating to a predetermined angle and stopping to drive the workpiece to rotate around the central axis of the small turntable 400. Through the sequential cooperation of multiple stations, 360° polishing of the workpiece and fixed designated surface grinding can be achieved.

[0073] Further, refer to Figure 1-4 In some embodiments, before the small turntable 400 reaches the second station or before reaching the second station, the small turntable 400 switches from the continuous power rotation state to the fixed position state, and the process of switching the small turntable 400 from the continuous power rotation state to the fixed position state includes executing a calibration positioning strategy, and the calibration positioning strategy includes:

[0074] The small turntable 400 is rotated to the initial alignment position, and after the angle detection calibration is performed on the rotation number detection member 700 corresponding to the small turntable 400, the predetermined angle is rotated according to the initial alignment position to the positioning and fixing state.

[0075] Through the above-mentioned implementation mode, the calibration positioning strategy is executed when the small turntable 400 switches from a continuous powered rotation state to a positioned fixed state. The calibration positioning strategy includes rotating the small turntable 400 to an initial alignment position, performing angle detection and calibration on the rotation circle detection part 700 corresponding to the small turntable 400, and then rotating a predetermined angle according to the initial alignment position to a positioned fixed state, thereby reducing polishing deviation and improving polishing quality through angle detection and calibration.

[0076] In addition, in order to facilitate understanding of the present invention, the complete polishing working principle is briefly introduced below:

[0077] 1. Automatically determine whether the position of the small turntable 400 driven by the rotation of the large turntable 200 is divisible by 360°. For example, in a multi-station disc polishing machine with four stations, the four stations are separated by 90°, and the corresponding interval of the small turntable 400 is also divisible by 360°. Of course, the number of stations is not limited, and can be 2, 3, 4, 5, or 6. The corresponding interval of each station is divisible by 360°, and the corresponding interval of each small turntable 400 is also divisible by 360°. The number of small turntables 400 is equal to the number of stations, or an integer multiple of the number of stations.

[0078] 2. According to the basic coordinates of the large turntable 200 and the small turntable 400, the small turntable 400 is allocated to each workstation;

[0079] 3. Each station polishes the workpiece carried on the small turntable 400 that circulates to its position. This cycle can be a one-by-one, intermittent or regular forward and backward cycle.

[0080] Furthermore, through the above principle, the small turntable 400 can be switched between different workstations, and corresponding polishing processing can be performed at different workstations.

[0081] Further, in some embodiments, reference Figure 1-4 The process of switching the small turntable 400 from the continuous power rotation state to the fixed position state includes executing a calibration positioning strategy. In this step, preferably, the following steps are included:

[0082] For the same small turntable 400, during the process of the large turntable 200 driving the small turntable 400 to move from the first station to the second station by rotating, the calibration positioning strategy is selectively executed according to a preset frequency, and the preset frequency includes one of each time and every preset number of times. Specifically, it can be each time.

[0083] By setting the calibration positioning strategy to be executed during the process of the large turntable 200 driving the small turntable 400 to move from the first station to the second station through rotation, when the large turntable 200 rotates to the corresponding station, the polishing mechanism can directly perform polishing and grinding, which is conducive to improving the polishing efficiency. By performing the calibration positioning strategy every time, poor polishing can be minimized.

[0084] In some embodiments, reference Figure 1-4 , the polishing method of the multi-station disc polishing machine also includes:

[0085] Step 5: Deviation detection of the workpiece after polishing can be done manually or by equipment, such as visual detection or infrared ranging detection. The polishing deviation data of the workpiece can be manually input into the multi-station disc polishing machine, or it can be automatically obtained after visual detection or infrared ranging detection. When the polishing deviation data is greater than the deviation threshold, fault information is output. Fault monitoring can be achieved in the above manner, which is convenient for rapid identification of deviation problems.

[0086] Of course, in some other embodiments, reference Figure 1-4 , before executing the calibration positioning strategy, it also includes:

[0087] Step 0.0, performing deviation detection on the workpiece after polishing to obtain polishing deviation data of the workpiece;

[0088] Step 0.1: When the polishing deviation data is greater than the deviation threshold, the calibration positioning strategy is executed in the process that the corresponding large turntable 200 drives the small turntable 400 to move from the first station to the second station by rotating.

[0089] Through the above method, the calibration positioning strategy can be selectively executed to improve the polishing efficiency.

[0090] In some embodiments, reference Figure 1-4 , executing the calibration positioning strategy also includes:

[0091] Each time the corresponding small rotating disk 400 rotates to the initial alignment position, the corresponding calibration time is recorded and the cumulative number is calculated;

[0092] Analyze the cumulative number of small rotating disks 400 or calculate the calibration frequency based on each calibration moment;

[0093] If the corresponding cumulative number is greater than the first preset threshold or the corresponding calibration frequency is greater than the second preset threshold, fault information is output.

[0094] In some cases, the deviation problem may not be solved by simply executing the calibration positioning strategy. In this case, most of the time, a fault problem has occurred. The above method is helpful to quickly identify the fault problem and then send out fault information for user analysis and reference. The fault information can be sound, text, or image information, without specific limitation.

[0095] Explanatory, the rotation number detection part 700 is an existing rotation angle encoder, and then the small turntable 400 is rotated to the physical zero position of the rotation number detection part 700 for angle detection, and then the detection value obtained by the rotation number detection part 700 is reset to zero, thereby achieving calibration.

[0096] In addition, during polishing, the consistency and uniformity of polishing need to be ensured. The traditional approach is to install a pressure sensor. However, in a multi-station disc polishing machine disclosed in a Chinese patent with publication number CN118664483A, since the large turntable 200 and the small turntable 400 need to rotate, installing a pressure sensor is not suitable.

[0097] For the above problems, refer to Figure 1-5 In some embodiments, the polishing method of the multi-station disc polishing machine further includes:

[0098] Step S1, obtaining a preset current value of a polishing motor of a polisher and a real-time current value during polishing;

[0099] Step S2, determining the current difference according to the preset current value and the real-time current value;

[0100] Step S3: According to the current difference, control the corresponding polishing mechanism to perform a feed polishing action.

[0101] It does not need to install a pressure sensor. It is directly based on the real-time current value of the polishing motor when performing polishing work. By combining the preset current value to perform current difference, it is possible to understand whether the feeding polishing action of the polishing mechanism is appropriate.

[0102] The above steps S1 to S3 may be performed in the step of performing 360° polishing on the workpiece by the polishing mechanism corresponding to the first station, and in the step of performing grinding on a designated surface of the workpiece by the polishing mechanism corresponding to the second station.

[0103] In some embodiments, reference Figure 1-5 Step S3, according to the current difference, controlling the corresponding polishing mechanism to perform the feeding polishing action includes:

[0104] Step S3.1, controlling the displacement assembly corresponding to the polisher to drive the corresponding polisher to adjust its position along at least one of the first direction, the second direction, and the third direction, so that the absolute value of the current difference approaches zero.

[0105] Specifically, when the feed is excessive, the feed can be appropriately reduced; when the feed is insufficient, the feed can be appropriately increased. The feed can be a gradient feed, and the feed amount of each gradient is reasonably set to achieve flexible adjustment of the position so that the absolute value of the current difference tends to zero, which is conducive to ensuring the consistency and uniformity of polishing.
