Description

Technical Field

[0001] This invention relates to the field of physical descaling technology, specifically to descaling methods and systems. Background Technology

[0002] In physical descaling operations, it is often necessary to descale different types of workpieces (generally irregular-shaped parts), as the shapes and sizes of different types of workpieces are not the same.

[0003] In related technologies, the descaling quality of different types of workpieces varies, and the descaling efficiency also differs greatly, which greatly affects product quality and production efficiency. Summary of the Invention

[0004] This invention aims to address, to a certain extent, one of the technical problems in related technologies. To this end, this invention provides a descaling method, an electronic device, a computer-readable medium, and a descaling system, which can effectively improve processing quality and descaling efficiency.

[0005] To achieve the above objectives, a first aspect of the present invention discloses a descaling method and a control module for a descaling system. The descaling system includes a descaling module, which includes a suspension bracket and a turbine. The suspension bracket is used to suspend a workpiece, and the turbine is used to be positioned on one side of the workpiece and to propel abrasive material onto the surface of the workpiece. The descaling method includes the following steps:

[0006] Obtain the end position information of both ends of the suspended workpiece in the height direction;

[0007] Obtain the angle information between the nozzle of the turbine and the workpiece at both ends corresponding to the height direction of the workpiece, and determine the starting point of the corresponding turbine nozzle's spray range based on the obtained angle information.

[0008] When the starting point of the turbine injection range is located outside the area set at the end position corresponding to the workpiece,

[0009] A first adjustment signal is sent to the turbine, the first adjustment signal being used to control the turbine nozzle to rotate relative to the workpiece, so that the starting point of the turbine's spray range moves to a set area at a distance from the end of the workpiece.

[0010] In this technical solution, the specific end position of the workpiece after suspension and fixation is determined by detecting the outline of the workpiece. The starting point of the turbine's spray range is adjusted according to the actual end position of the workpiece so that the spray range covers the end of the workpiece, avoiding the problem of missing descaling at the end of the workpiece. Moreover, by controlling the starting point of the spray range within the set area, the waste of abrasive caused by an excessively large empty spray area can also be avoided, thus improving work efficiency.

[0011] Furthermore, the descaling module includes a first cleaning unit and a second cleaning unit arranged sequentially along the conveying direction. The first cleaning unit includes four first turbines located in different orientations, and the second worm gear unit includes four second turbines located in different orientations. The orientations of the four first turbines and the four second turbines are different. The descaling method includes: acquiring the angle information between the nozzles of the first turbines and the workpiece at both ends of the workpiece height direction and the workpiece, and when the starting point of the sandblasting range of the first turbines and the second turbines is located outside the set area at the corresponding end position of the workpiece along the height direction, sending a corresponding first adjustment signal to the corresponding first turbines and the second turbines.

[0012] Furthermore, the descaling method also includes:

[0013] A scanning signal is sent to the scanning module so that the scanning module can scan and detect the surface of the workpiece after it has been cleaned by the descaling module;

[0014] The scanning module receives the scanning detection results and obtains the actual grayscale value of the workpiece surface;

[0015] The actual grayscale value is periodically compared with the reference grayscale value;

[0016] When the actual grayscale value is lower than the reference grayscale value.

[0017] A third adjustment signal is sent to the turbine or the conveying module to increase the speed of the turbine impeller or decrease the conveying speed of the conveying module.

[0018] By inspecting the surface of the workpiece after it has been processed by the descaling module and adjusting the turbine's spray range a second time, the descaling quality of the workpiece is dynamically ensured. Combined with the static adjustments made before descaling, the dynamic and static adjustments work together to effectively improve the descaling quality of the workpiece.

[0019] Furthermore, the descaling method further includes: sending a first scanning signal to the scanning module so that the scanning module scans and detects the surface of the workpiece to be cleaned;

[0020] The scanning module receives the scanning detection results and obtains the first actual grayscale values ​​of different areas on the surface of the workpiece to be cleaned.

[0021] A second scanning signal is sent to the scanning module so that the scanning module can scan and detect the surface of the workpiece after it has been cleaned by the descaling module;

[0022] The scanning detection results of the scanning module are received, and the second actual grayscale values ​​of different areas on the surface of the cleaned workpiece are obtained.

[0023] Periodically compare the first and second actual gray values ​​of the corresponding regions;

[0024] Based on the comparison results, a control signal is sent to the turbine or the delivery module.

[0025] Furthermore, the first actual grayscale value includes a first end grayscale value and a first middle grayscale value, and the second actual grayscale value includes a second end grayscale value and a second middle grayscale value. The first end grayscale value and the second end grayscale value represent the grayscale values ​​of the same area at the end of the workpiece, and the first middle grayscale value and the second middle grayscale value represent the grayscale values ​​of the same area in the middle of the workpiece.

[0026] Periodically comparing the first and second actual grayscale values ​​of the corresponding regions, and sending control signals to the turbine or conveying module based on the comparison results, includes:

[0027] Compare the grayscale values ​​of the first end and the second end;

[0028] Compare the grayscale values ​​of the first and second middle sections;

[0029] When the difference between the gray values ​​of the first end and the second end is less than a first set difference, and the difference between the gray values ​​of the first end and the second end and the difference between the gray values ​​of the first middle part and the second middle part is greater than a second set difference;

[0030] A second adjustment signal is sent to the turbine, the second adjustment signal being used to control the turbine nozzle to rotate relative to the workpiece, so that the starting point of the turbine's spray range moves toward a set area at the end of the workpiece.

[0031] Furthermore, the first set difference ranges from 0 to 10, and the second set difference ranges from 5 to 15.

[0032] Furthermore, the comparison period is T=L / V, where: V is the current actual operating speed of the production line, and L is the distance between the output ends of the scanning module and the descaling module.

[0033] Furthermore, the defined area is a region located outside the end of the workpiece and 5mm to 10mm away from the end of the workpiece.

[0034] A second aspect of the present invention discloses a descaling system, the descaling system comprising a conveying module, a descaling module, a scanning module, and a control module, the control module being used to implement the descaling method described in the first aspect, the suspension bracket being disposed on the conveying module, the turbine being disposed on one side of the conveying module along the conveying direction of the conveying module, the scanning module being disposed on the rear side of the descaling module, the scanning module comprising a vision scanning system disposed on one side of the conveying module, the vision scanning system comprising a scanning module and a control element for controlling the scanning module to periodically scan, the control element being communicatively connected to the control module.

[0035] Furthermore, the descaling system also includes a feeding module, a pre-cleaning module, a rinsing module, a drying module, and a discharging module, which are arranged sequentially along the conveying direction of the conveying module.

[0036] Furthermore, the conveying module includes at least one of a single-chain conveying structure and an accumulation chain conveying structure, and a set distance is formed between the outlet of the descaling module and the drying module.

[0037] The descaling system provided by this invention has a similar descaling effect reasoning process to the aforementioned descaling methods, and will not be repeated here.

[0058] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain the present invention and should not be construed as limiting the invention.

[0059] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this invention. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0060] In related technologies, descaling systems typically use a turbine to blast abrasive (usually steel shot) onto a workpiece. The turbine's blasting range is generally fan-shaped, with a relatively large amount of sand blasted near the turbine nozzle and a relatively small amount blasted further away. (See Appendix) Figure 3 As shown, in actual operation, the descaling quality of different areas of the workpiece (areas at different distances from the sandblasting nozzle of the turbine) will be different, which will cause the brightness of different areas on the same workpiece to be inconsistent. Moreover, the difference in descaling effect for workpieces of different sizes is also greater.

[0061] See appendix Figures 1 to 9 The first aspect of the present invention discloses a descaling method and a control module for a descaling system. The descaling system includes a descaling module, which includes a suspension bracket and a turbine. The suspension bracket is used to suspend a workpiece, and the turbine is used to be positioned on one side of the workpiece and to propel abrasive material onto the surface of the workpiece. The descaling method includes the following steps:

[0062] S1. Obtain the end position information of both ends of the suspended workpiece in the height direction;

[0063] S2. Obtain the angle information between the nozzle of the turbine and the workpiece corresponding to both ends of the workpiece height direction (in actual operation, since the position of the suspension bracket is determined, the position of the corresponding workpiece is also determined, and the angle of the nozzle relative to the workpiece can be detected by detecting the orientation of the turbine nozzle), and determine the starting point of the corresponding turbine nozzle spray range based on the obtained angle information.

[0064] S3. When the starting point of the turbine injection range is located outside the area set at the end position corresponding to the workpiece,

[0065] A first adjustment signal is sent to the turbine, the first adjustment signal being used to control the turbine nozzle to rotate relative to the workpiece, so that the starting point of the turbine's spray range moves to a set area at a distance from the end of the workpiece.

[0066] The descaling method in this embodiment is applied to a suspended descaling system. During the descaling operation, the workpiece is suspended and fixed on the suspension bracket. This suspended fixing method allows multiple turbines to be set at different positions around the workpiece, thereby enabling simultaneous cleaning of different positions of the workpiece and improving the cleaning efficiency of the workpiece.

[0067] In actual operation, due to the different suspension points of different workpieces and the different sizes of different workpieces, the top of the workpiece after being suspended will be at different heights, and the bottom of the workpiece will also be at different heights.

[0068] Before performing the descaling operation, the descaling method in this embodiment first detects the actual position of the workpiece to determine the top and bottom ends of the workpiece in the height direction. The detection of the actual position of the workpiece can be performed by image recognition (after the workpiece is suspended and fixed, the actual position of the workpiece is determined by taking a picture of the workpiece), or by traditional detection methods (first, the actual size of the workpiece and the specific position of the workpiece suspension point are measured, and then the actual positions of the two ends of the workpiece in the height direction are obtained by traditional calculation methods, and the calculated actual positions of the two ends of the workpiece are written into the control module).

[0069] By detecting the actual position of the workpiece, it is better able to adapt to the descaling requirements of different workpieces during actual operation. Moreover, before descaling, the position of the turbine nozzle is adjusted according to the time position of the workpiece (the descaling requirements of different workpieces are different each time), so that the spray range of the turbine can completely cover the entire workpiece, avoiding the problem that the end of the workpiece may be missed due to the inconsistent starting point of the spray range.

[0070] Furthermore, in this embodiment, the spray range of the turbine is adjusted by adjusting the angle of the turbine nozzle relative to the workpiece. In actual operation, the spray range of the turbine is generally related to the distance between the workpiece and the turbine impeller center, the nozzle opening size, and the angle of the nozzle opening relative to the workpiece. In actual setup, the distance between the workpiece and the turbine impeller center and the nozzle opening size are generally kept constant. Therefore, the spray range of the turbine can be changed by adjusting the nozzle angle.

[0071] This embodiment obtains the end position of the workpiece and the angle of the nozzle relative to the workpiece, and can determine the relative positional relationship between the starting point of the turbine nozzle's spray range and the end position of the workpiece. In actual operation, when the turbine's spray range is outside the set area of ​​the workpiece end position, this embodiment adjusts the opening angle of the turbine nozzle to change the turbine's spray range, so that the spray range covers the end of the workpiece, avoiding the problem of missing descaling at the end of the workpiece. Moreover, by controlling the starting point of the spray range within the set area, it can also avoid the waste of abrasive caused by an excessively large empty spray area, thus improving work efficiency.

[0072] The designated area mentioned in this embodiment is generally set to be located outside the workpiece end and 5mm to 10mm away from the workpiece end. When the starting point of the turbine's spray range is within this area, it can completely cover the end position of the workpiece, and the proximity of the starting point of the spray range to the workpiece end also improves the descaling quality of the workpiece.

[0073] In this embodiment, the adjustment of the nozzle angle of the turbine can be achieved by rotating the nozzle individually during actual operation, or by setting the turbine as a whole to be rotatable relative to the frame (the frame being the base for mounting the turbine), thereby adjusting the turbine as a whole to change the nozzle angle.

[0074] As one embodiment of the present invention, see Appendix Figure 2 The descaling method further includes step S4: sending a scanning signal to the scanning module so that the scanning module scans and detects the surface of the workpiece after it has been cleaned by the descaling module;

[0075] S5. Receive the scanning detection result from the scanning module and obtain the actual grayscale value of the workpiece surface;

[0076] S6. Periodically compare the actual grayscale value with the reference grayscale value;

[0077] When the actual grayscale value is lower than the reference grayscale value.

[0078] A third adjustment signal is sent to the turbine or the conveying module to increase the speed of the turbine impeller or decrease the conveying speed of the conveying module.

[0079] In this embodiment, in addition to the initial adjustment of the turbine's spray range before descaling, a secondary adjustment of the turbine's spray range can be performed during the descaling process. Specifically, in the actual operation, the descaling system in this embodiment detects the surface of the descaled workpiece (by acquiring an image of the processed workpiece using a visual scanning system and analyzing the surface quality of the workpiece based on the image), calculates the grayscale of the workpiece surface based on the detection results, compares it with a pre-set baseline grayscale value, and then adjusts the turbine's spray range a second time based on the comparison results, thus achieving dynamic adjustment during the descaling process.

[0080] The reference grayscale value in this embodiment can be obtained by conducting sample testing on the workpiece in the early stage, or it can be obtained according to the customer's needs. The reference grayscale value is written into the control module before operation.

[0081] In this embodiment, when the actual gray value is lower than the reference gray value, it indicates that the descaling effect on the workpiece surface is not up to standard, that is, the descaling quality is unqualified. At this time, the spray range can be adjusted by adjusting the angle of the turbine nozzle. As mentioned above, the descaling effect is not consistent in different areas of the spray range. The purpose of this embodiment is to match the areas with better descaling effect with the areas with inconsistent gray values, thereby improving the descaling effect. When the actual gray value is higher than the reference gray value, it indicates that the quality of the workpiece surface meets the requirements. At this time, no adjustment is required, and the work can continue to be carried out according to the original process parameters.

[0082] In this embodiment, by periodically inspecting the surface of the workpieces after descaling on the production line, unqualified workpieces can be detected in a timely manner during actual operation, avoiding a large number of unqualified workpieces caused by unexpected situations during the work process, thus reducing the workload of secondary processing and improving work efficiency.

[0083] It should be noted that in actual operation, this embodiment can adjust the angle of the turbine nozzle when the grayscale does not meet the standard. This is a local adjustment within the spray range that covers the end of the workpiece. It is just a further fine-tuning within this set area to make the area with the best descaling effect of the spray range cover the area with substandard grayscale as much as possible, thereby improving the surface quality of the workpiece. In addition, the conveying speed of the conveying module can also be adjusted. For example, reducing the conveying speed of the conveying module allows the workpiece to be cleaned by the descaling module for a longer time, thereby ensuring the grayscale value.

[0084] In addition, it should be noted that in actual operation, in order to avoid errors, the turbine can be set to adjust only when multiple workpieces with non-compliant grayscale are detected within the same detection cycle, rather than adjusting it every time a single non-compliant grayscale is detected.

[0085] As one embodiment of the present invention, the descaling method further includes: sending a first scanning signal to the scanning module so that the scanning module scans and detects the surface of the workpiece to be cleaned;

[0086] The scanning module receives the scanning detection results and obtains the first actual grayscale values ​​of different areas on the surface of the workpiece to be cleaned.

[0087] A second scanning signal is sent to the scanning module so that the scanning module can scan and detect the surface of the workpiece after it has been cleaned by the descaling module;

[0088] The scanning detection results of the scanning module are received, and the second actual grayscale values ​​of different areas on the surface of the cleaned workpiece are obtained.

[0089] Periodically compare the first and second actual gray values ​​of the corresponding regions;

[0090] Based on the comparison results, a control signal is sent to the turbine or the delivery module.

[0091] Furthermore, the first actual grayscale value includes a first end grayscale value and a first middle grayscale value, and the second actual grayscale value includes a second end grayscale value and a second middle grayscale value. The first end grayscale value and the second end grayscale value represent the grayscale values ​​of the same area at the end of the workpiece, and the first middle grayscale value and the second middle grayscale value represent the grayscale values ​​of the same area in the middle of the workpiece.

[0092] Periodically comparing the first and second actual grayscale values ​​of the corresponding regions, and sending control signals to the turbine or conveying module based on the comparison results, includes:

[0093] Compare the grayscale values ​​of the first end and the second end;

[0094] Compare the grayscale values ​​of the first and second middle sections;

[0095] When the difference between the gray values ​​of the first end and the second end is less than a first set difference, and the difference between the gray values ​​of the first end and the second end and the difference between the gray values ​​of the first middle part and the second middle part is greater than a second set difference;

[0096] A second adjustment signal is sent to the turbine, the second adjustment signal being used to control the turbine nozzle to rotate relative to the workpiece, so that the starting point of the turbine's spray range moves toward a set area at the end of the workpiece.

[0097] Furthermore, the first set difference ranges from 0 to 10, and the second set difference ranges from 5 to 15.

[0098] The descaling method in this embodiment adds a process of inspecting the surface of the workpiece before and after cleaning. By comparing the surface of the workpiece before and after cleaning, the cleaning effect can be clearly and intuitively understood.

[0099] Specifically, when inspecting the surface of a workpiece before and after cleaning, the surface of different areas of the workpiece is inspected separately. By comparing the surface grayscale values ​​of the corresponding areas, the descaling quality of the descaling module can be understood more accurately.

[0100] In this embodiment, the surface area of ​​the workpiece is divided into an end area and a middle area. Of course, in actual setup, more suitable areas can be selected for comparative analysis.

[0101] The cleaning of the end area is generally an area that is easily overlooked. When the change in grayscale value of the workpiece end before and after cleaning is small (i.e., the difference between the first and second end grayscale values ​​is less than a first set difference), it indicates that the end of the workpiece may not have been blasted, but it is also possible that the workpiece itself has a low grayscale value. For greater precision, by adding an additional condition (the difference between the first and second end grayscale values ​​and the difference between the first and second middle grayscale values ​​is greater than a second set difference), the comparison of the differences can more accurately determine whether the dark grayscale is due to the workpiece itself or due to incomplete blasting, thus allowing for more precise adjustments.

[0102] When the difference between the gray values ​​of the first end and the second end is less than the first set difference, and the difference between the gray values ​​of the first end and the second end and the difference between the gray values ​​of the first middle part and the second middle part is also less than the second set difference, it indicates that the problem is with the workpiece itself and no adjustment is needed.

[0103] In one embodiment of the present invention, the descaling module includes a first cleaning unit and a second cleaning unit arranged sequentially along the conveying direction. The first cleaning unit includes four first turbines located in different orientations, and the second worm gear unit includes four second turbines located in different orientations. The orientations of the four first turbines and the four second turbines are different. The descaling method includes: acquiring the angle information between the nozzles of the first turbines and the workpiece at both ends of the workpiece height direction and the workpiece, and when the starting point of the sandblasting range of the first turbines and the second turbines is located outside the set area at the corresponding end position of the workpiece along the height direction, sending a corresponding first adjustment signal to the corresponding first turbines and the second turbines.

[0104] In the descaling system of this embodiment, each workpiece is blasted by multiple turbines. Generally, the descaling system can include two cleaning units (a first cleaning unit and a second cleaning unit). The first cleaning unit and the second cleaning unit each include four turbines (a first turbine and a second turbine). That is, each workpiece is sandblasted by eight turbines. The eight turbines are distributed in different positions on the workpiece, which can clean the workpiece from eight different directions. Each turbine has a certain cleaning range. In this way, the eight turbines cooperate with each other. In actual setup, four turbines can be designed to start descaling from the top of the workpiece, and the other four turbines can clean from the bottom of the workpiece. This can better cover the entire surface of the workpiece.

[0105] For details, please see the appendix. Figures 12 to 15 Taking a wheel spoke as an example, the spray range and sandblasting direction of the descaling module are explained. Eight turbines are distributed in pairs on both sides of the conveying module, with each pair of turbines forming a cleaning station. For ease of description, the eight turbines in the descaling module are divided into four stations along the conveying direction: Descaling Station #1, Descaling Station #2, Descaling Station #3, and Descaling Station #4. For the descaling process of the two first turbines at Descaling Station #1 on the workpiece (taking a wheel spoke as an example), please refer to the appendix. Figure 12 For the spray descaling range of the two first turbines at descaling position #2, please refer to the appendix. Figure 13 For the spray descaling range of the two second turbines at descaling position #3 on the workpiece, please refer to the appendix. Figure 14 For the spray descaling range of the two second turbines at descaling position #4, please refer to the appendix. Figure 15 As can be seen, after the workpiece passes between the eight turbines as the conveying module passes through, the surface of the workpiece can be completely covered by the spray range of the turbines, achieving a better descaling effect. In the figure above, side A and side B represent the two opposite sides of the conveying module.

[0106] It should be noted that, in actual operation, the nozzle angle of each turbine can be adjusted using the corresponding adjustment method mentioned above in the descaling method.

[0107] Of course, in some descaling systems, only the four directions of turbine jet direction can be equipped. In this case, the rotation of the workpiece itself can be combined (for example, the suspension bracket can be set as a structure that can drive the workpiece to rotate). At this time, the effect of completely covering the workpiece surface can also be achieved.

[0108] As one embodiment of the present invention, see Appendix Figure 4 The comparison period mentioned above is T=L / V, where: V is the current actual operating speed of the production line, and L is the distance between the output ends of the scanning module and the descaling module.

[0109] In actual production, the surface of the descaled workpiece needs to be dried before accurate grayscale values ​​can be obtained through image recognition. Therefore, a drying module is usually set up between the descaling module and the scanning module on the production line. This creates a certain distance between the scanning module and the descaling module. When the scanning module detects a workpiece with an unacceptable surface grayscale and adjusts the turbine in the descaling module, the cleaned workpiece will only reach the scanning module after a certain interval. Therefore, by matching the scanning module with this interval, the scanning module can determine whether the cleaning effect of the adjusted workpiece surface meets the requirements, thus providing feedback on the adjustment.

[0110] In addition, it should be noted that the period mentioned above in this embodiment is the comparison period, not the scanning period. The scanning module scans continuously during scanning, and the scanning frequency is generally multiple times per second. However, when comparing, the distance between the scanning module and the descaling module needs to be considered to make the control more precise. In this embodiment, multiple scanning modules can generally be set and distributed in different positions of the workpiece, so that the workpiece can be scanned more comprehensively.

[0111] The descaling method in this embodiment adds more possible adjustment methods. Since adjusting the nozzle angle to adjust the spray range has certain limitations, when adjusting the turbine nozzle angle still cannot meet the gray scale requirements of the workpiece surface, the impact effect of the steel shot can be further increased by adjusting the turbine impeller speed (increasing the initial speed of the steel shot being sprayed) and reducing the workpiece conveying speed. In addition, combined with the adjustment of the turbine nozzle angle, it is more helpful to improve the descaling quality of the workpiece surface.

[0112] As a second aspect of the present invention, an electronic device is provided, wherein, as Figure 10 As shown, the electronic device includes:

[0115] The electronic device may also include one or more I / O interfaces 103 connected between the processor 101 and the memory 102, configured to enable information interaction between the processor 101 and the memory 102.

[0116] The processor 101 is a device with data processing capabilities, including but not limited to a central processing unit (CPU); the memory 102 is a device with data storage capabilities, including but not limited to random access memory (RAM, more specifically SDRAM, DDR, etc.), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), and flash memory (FLASH); the I / O interface (read-write interface) is connected between the processor and the memory, enabling information exchange between the processor and the memory, including but not limited to a data bus (Bus).

[0117] In some embodiments, the processor 101, memory 102, and I / O interface 103 are interconnected via bus 104, and thus connected to other components of the electronic device.

[0118] As a third aspect of the invention, such as Figure 11 As shown, a computer-readable medium is provided, on which a computer program is stored, wherein the computer program, when executed by a processor, implements the above-described descaling method provided by the present invention.

[0119] A fourth aspect of the present invention discloses a descaling system, see appendix. Figure 4 The descaling system includes a conveying module, a descaling module, a scanning module, and a control module. The control module is used to implement the descaling method described in the first aspect (wherein the control module can generally be the electronic device mentioned in the second aspect). The suspension bracket is disposed on the conveying module, the turbine is disposed on one side of the conveying module along the conveying direction of the conveying module, and the scanning module is disposed on the rear side of the descaling module. The scanning module includes a vision scanning system disposed on one side of the conveying module. The vision scanning system includes a scanning module and a control element that controls the scanning module to scan periodically. The control element is communicatively connected to the control module.

[0120] The conveying module in this embodiment is used to move workpieces between different workstations. Referring to the attached drawings, the conveying module in this embodiment adopts a ring-shaped guide rail.

[0121] The descaling system in this embodiment also includes a drying module, which is located between the descaling module and the scanning module. The drying module is used to dry the workpiece after it has been cleaned by the descaling module. The descaling module in this embodiment includes two cleaning units, each of which includes four turbines located in different positions. In total, the eight turbines can clean the workpiece from different directions.

[0122] The descaling system in this embodiment further includes a feeding module, a pre-cleaning module, a rinsing module, a drying module, and a discharging module, which are arranged sequentially along the conveying direction of the conveying module.

[0123] The entire descaling process of the descaling system in this embodiment is as follows: loading, pre-cleaning, descaling, rinsing, drying, and unloading. In actual setup, a predetermined distance is formed between the outlet of the descaling module and the drying module (for example, it can be located on the opposite side of the curved section opposite the descaling module in the diagram). Besides saving the overall line length, another reason is that suspended irregularly shaped parts typically have a lot of residual working fluid on their surface after cleaning. If they immediately enter the drying device, not only will some splashed working fluid enter the drying device, but the workpiece itself will also carry a lot of working fluid, causing high pressure in the drying device and excessive consumption of working fluid. Therefore, allowing the workpiece to leave the rinsing area, travel with the chain for a few minutes, and then return to the drying device not only avoids the above problems and reduces the power consumption of the drying device, making it more energy-efficient, but also allows the working fluid splashed from the workpiece and outlet to be collected in the foundation pit for reuse.

[0124] The invention relates to a conveying module comprising at least one of a single-chain conveyor structure and an accumulation chain conveyor structure. The single-chain conveyor structure consists of a single chain throughout the entire cycle, with a uniform speed at each position, for example, 5 meters per minute. The advantages of the single-chain structure are its simplicity, high reliability, and ease of control. Alternatively, it can be configured as an accumulation chain conveyor structure, which has three circulating conveyor lines. One line on the cleaning unit side has a separate cycle and drive, maintaining a speed of, for example, 5 meters per minute. A second cycle exists at the loading and unloading modules, with a speed of, for example, 6 meters per minute (this speed will be faster than the first cycle because it needs to make up for the distance wasted during loading and unloading). The third cycle is a separate cycle containing the suspension bracket. This cycle can be understood as a circular channel with an independent carrier. The suspension bracket is installed below the carrier, and the workpiece is mounted on the suspension bracket. The trolley has no power and connects to or disconnects from the first or second circulating chain through physical connection and opening mechanisms to obtain corresponding speed, power, or stillness. The advantage of using an accumulation chain conveyor structure is that, without affecting the descaling speed of the cleaning unit, separate pause times (e.g., 5-10 seconds) can be obtained in the loading and unloading areas, which can facilitate manual or robotic loading and unloading and reduce workload.

[0125] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
