Description

Technical Field

[0001] This invention belongs to the field of grinding machine technology, and particularly relates to a method, system and grinding machine for grinding the surface of workpieces after hot-dip galvanizing. Background Technology

[0002] To ensure quality, a significant amount of manpower and resources are required to treat the surface of workpieces after hot-dip galvanizing before final shipment and packaging, and manual processing is inefficient. Currently designed friction-type automated grinding machines or rust removal machines can automatically grind workpieces, solving the problem of requiring a large amount of manpower and resources.

[0003] The inventors discovered that when using automated grinding machines or rust removal machines for surface grinding, especially when grinding a batch of workpieces, a sufficiently long grinding time is often required to ensure the grinding effect. However, prolonged grinding not only causes excessive wear on some workpiece surfaces but also results in energy consumption and time waste. On the other hand, grinding time that is too short results in a poor grinding effect on the workpiece surface. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a method, system, and grinding machine for grinding the surface of workpieces after hot-dip galvanizing. This invention considers the grinding difficulty and the degree of surface contamination to determine the grinding time, ensuring the grinding effect while avoiding damage to the workpiece surface caused by excessive grinding time, thus solving the problems of energy consumption and time waste.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, the present invention provides a method for grinding the surface of a workpiece after hot-dip galvanizing, comprising:

[0008] Based on the structural type and image information of a single workpiece, the complexity of the workpiece structure and the degree of surface contamination of a batch of workpieces are determined respectively;

[0009] The required grinding machine workload is determined based on the total hot-dip galvanizing process time and the complexity of the workpiece structure; and the required grinding time is determined based on the degree of surface contamination of the batch of workpieces.

[0011] Furthermore, the structural complexity of a workpiece with no curved surfaces and no dead corners or bends is defined as Level 1 structure; the structural complexity of a workpiece with curved surfaces and no dead corners or bends is defined as Level 2 structure; when the workpiece has no curved surfaces, but has dead corners and bends, and the total number of dead corners and bends does not exceed a preset number, the structural complexity of the workpiece is defined as Level 3 structure; when the total number of dead corners and bends exceeds a preset number, the structural complexity of the workpiece is defined as Level 4 structure.

[0012] Furthermore, the degree of surface contamination of a batch of workpieces is equal to the ratio of the contaminated area in the image to the overall area of ​​the image;

[0013] When there is no overlap in a batch of workpieces, the surface dirt level of the batch of workpieces can be calculated by acquiring a single image.

[0014] When a batch of workpieces overlap, multiple images are acquired at different times, and the ratio of the dirty area to the overall area of ​​each image is calculated. The average of multiple ratios is the degree of surface dirt on the batch of workpieces.

[0015] Furthermore, the total process time multiplied by the first weight, plus the workpiece structural complexity multiplied by the second weight, is used as the basis for determining the working intensity of the grinding machine. The larger the basis value, the greater the working intensity of the grinding machine used.

[0016] Secondly, the present invention also provides a surface polishing system for workpieces after hot-dip galvanizing surface treatment, comprising:

[0017] The data acquisition module is configured to: acquire the total hot-dip galvanizing process time of a single workpiece in the batch of workpieces to be polished, the structural type of a single workpiece; and acquire the overall image information of the batch of workpieces.

[0020] The grinding control module is configured to control the grinding machine to grind the surface of the workpiece under a given working intensity and grinding duration.

[0021] Thirdly, the present invention also provides a polishing machine, including a working chamber and a turntable disposed within the working chamber via a drive mechanism; the drive mechanism is connected to a controller, the controller being configured to:

[0022] The process involves obtaining the total hot-dip galvanizing process time and structural type of a single workpiece from a batch of workpieces to be polished; and also obtaining the overall image information of the batch of workpieces.

[0023] Based on the structural type and image information of a single workpiece, the complexity of the workpiece structure and the degree of surface contamination of a batch of workpieces are determined respectively;

[0024] The required working intensity of the drive mechanism is determined based on the total duration of the hot-dip galvanizing process and the complexity of the workpiece structure; and the required grinding time is determined based on the degree of surface contamination of the batch of workpieces.

[0025] The drive mechanism is controlled to process the workpiece based on a defined workload and grinding duration.

[0026] Furthermore, a first wire brush is provided at the center of the turntable; a second wire brush is provided on the surface of the turntable and on the inner surface of the working chamber; the first wire brush is a cylindrical wire brush.

[0027] Fourthly, the present invention also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the workpiece surface polishing method after hot-dip galvanizing surface treatment as described in the first aspect.

[0028] Fifthly, the present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the program to implement the steps of the workpiece surface polishing method after hot-dip galvanizing surface treatment as described in the first aspect.

[0029] In a sixth aspect, the present invention also provides a computer program product, the computer program product comprising a computer program, which, when executed by a processor, implements the steps of the workpiece surface polishing method after hot-dip galvanizing surface treatment as described in the first aspect.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. In this invention, the grinding time is determined based on the total duration of the hot-dip galvanizing process, the complexity of the workpiece structure, and the degree of surface contamination of the batch of workpieces. The grinding difficulty and the degree of surface contamination are taken into account. The grinding time determined in this way can avoid damage to the workpiece surface caused by excessive grinding time while ensuring the grinding effect, thus solving the problems of energy consumption and time waste. At the same time, the required working intensity of the grinding machine is determined according to the total duration of the hot-dip galvanizing process and the complexity of the workpiece structure. By increasing the working intensity, the grinding time can be further shortened while ensuring the grinding effect.

[0032] 2. In the working chamber of the grinding machine of the present invention, a turntable is set by a drive mechanism. Not only are steel wire brushes set on the surface of the turntable and the inner surface of the working chamber, but a cylindrical steel wire brush is also set in the middle of the turntable.

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0043] Example 1:

[0044] Hot-dip galvanizing is a process in which molten metal reacts with an iron substrate to create an alloy layer, thus bonding the substrate and the coating. The process begins with pickling the steel parts to remove iron oxide from their surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both, before being immersed in the hot-dip galvanizing bath.

[0045] Workpieces that have undergone hot-dip galvanizing, such as pipe fittings, instrument metal housings, power fittings, beams, columns, bolts, and supports, require significant manpower and resources to treat their surfaces before final shipment and packaging to ensure quality. Furthermore, manual processing is inefficient.

[0046] In response to the low efficiency of manual surface treatment of workpieces, the applicant first tried to solve the appearance problem by using cleaning fluid or other efficient methods, but failed to achieve the desired effect and the cost and pollution were high. The applicant also tried to use friction-type automated grinding machines or rust removal machines available on the market to automatically grind the workpiece surface, which could solve the problem of investing a lot of manpower and resources.

[0047] However, when using automated grinding machines or rust removal machines for surface polishing, especially for batch workpieces, a sufficiently long polishing time is often required to ensure the desired polishing effect. Prolonged polishing not only causes excessive wear on some workpiece surfaces but also results in wasted energy and time. Conversely, insufficient polishing time leads to poor surface polishing results. Excessive wear on the workpiece surface not only affects its appearance but can also increase the number of defective products in applications requiring high precision.

[0048] In response to the above problems, such as Figure 1 As shown, this embodiment provides a method for grinding the surface of a workpiece after hot-dip galvanizing, including:

[0049] The process involves obtaining the total hot-dip galvanizing process time and structural type of a single workpiece from a batch of workpieces to be polished; and also obtaining the overall image information of the batch of workpieces.

[0050] Based on the structural type and image information of a single workpiece, the complexity of the workpiece structure and the degree of surface contamination of a batch of workpieces are determined respectively;

[0051] The required grinding machine workload is determined based on the total hot-dip galvanizing process time and the complexity of the workpiece structure; and the required grinding time is determined based on the degree of surface contamination of the batch of workpieces.

[0052] The grinding machine is controlled to grind the surface of the workpiece based on a defined workload and grinding time.

[0053] Specifically, the grinding time is determined based on the total hot-dip galvanizing process time, the complexity of the workpiece structure, and the degree of surface contamination of the batch of workpieces. The grinding difficulty and the degree of surface contamination are taken into account. The grinding time determined in this way can ensure the grinding effect while avoiding damage to the workpiece surface caused by excessive grinding time, thus solving the problems of energy consumption and time waste. At the same time, the required working intensity of the grinding machine is determined according to the total hot-dip galvanizing process time and the complexity of the workpiece structure. By increasing the working intensity, the grinding time can be further shortened while ensuring the grinding effect.

[0054] Different workpieces have different requirements for their hot-dip galvanizing processes due to differences in structure and usage scenarios. In this embodiment, the total time spent on the hot-dip galvanizing process for a single workpiece is statistically analyzed. For some workpieces, a longer total hot-dip galvanizing process indicates a greater degree of surface contamination and greater difficulty in removing the contaminants. Conversely, for some workpieces, a shorter total hot-dip galvanizing process indicates a less severe degree of surface contamination and easier removal of the contaminants. Therefore, in this embodiment, the total hot-dip galvanizing process time is considered when determining the working intensity of the grinding machine. Optionally, the total hot-dip galvanizing process time can be determined by detecting the on / off duration of the corresponding equipment in the hot-dip galvanizing process or by using image recognition or other technologies.

[0055] Different types of workpieces have varying degrees of structural complexity. For example, some workpieces have relatively regular surfaces with no dead corners or curved surfaces, making surface treatment relatively easy. However, some workpieces have irregular surfaces, either overall or in parts, with many dead corners or curved surfaces, making surface treatment more difficult. Therefore, in this embodiment, the structural complexity of the workpiece is taken into account when determining the working intensity of the grinding machine.

[0056] In this embodiment, when determining the structural complexity, the structural complexity of a workpiece without curved surfaces and without dead corners or bends is defined as a Level 1 structure, such as a round bar structure or a sheet-like workpiece; the structural complexity of a workpiece with curved surfaces and without dead corners or bends is defined as a Level 2 structure, such as a rectangular bar workpiece; when the workpiece has no curved surfaces, but the structure has dead corners and bends, and the total number of dead corners and bends does not exceed a preset number, the structural complexity of the workpiece is defined as a Level 3 structure, such as a beam; when the total number of dead corners and bends exceeds a preset number, the structural complexity of the workpiece is defined as a Level 4 structure, such as bolts or complex instrument metal housings.

[0057] Understandably, the structural complexity of a first-level structure is less than that of a second-level structure; the structural complexity of a second-level structure is less than that of a third-level structure; and the structural complexity of a third-level structure is less than that of a fourth-level structure.

[0058] In this embodiment, each batch of workpieces is of the same type, and only one workpiece needs to be determined when assessing structural complexity. However, in other embodiments, the workpiece types differ when processing a single batch of workpieces. In this case, when assessing structural complexity, an overall image of the batch of test pieces is obtained, and the number of curved surfaces, dead corners, and bends is counted in the overall image. Specifically, the structural complexity of workpieces without curved surfaces, dead corners, or bends is defined as Level 1 structure, such as workpieces with round bar structures and / or sheet-like workpieces. The structural complexity of workpieces with curved surfaces, dead corners, or bends is defined as Level 2 structure, such as at least rectangular bar workpieces. When the workpiece has no curved surfaces, but has dead corners and bends, and the total number of dead corners and bends divided by the average number of workpieces does not exceed a preset number, the structural complexity of the workpiece is defined as Level 3 structure, such as at least beams. When the total number of dead corners and bends divided by the average number of workpieces exceeds a preset number, the structural complexity of the workpiece is defined as Level 4 structure, such as at least bolts or complex instrument metal housings.

[0059] In some embodiments, when a batch of workpieces does not overlap, a single overall image is directly acquired to count the number of curved surfaces, dead angles, and corners. When a batch of workpieces overlaps and is distributed on a container or transport equipment, an image is acquired using a camera or similar device. After shaking the container or allowing the transport equipment to move the workpieces for a certain period of time, a second image is acquired using the same camera or similar device. This process is repeated until a third, or more, image is acquired using the same camera or similar device. For multiple images, the number of curved surfaces, dead angles, and corners is counted separately. Then, the sum of all counts is divided by the number of images to obtain the final number of curved surfaces, dead angles, and corners. The average of the summed counts of curved surfaces, dead angles, and corners from multiple images is used as the final number of curved surfaces, dead angles, and corners, ensuring calculation accuracy.

[0060] The degree of surface contamination of a batch of workpieces is equal to the ratio of the contaminated area in the image to the overall area of ​​the image. In some embodiments, the batch of workpieces are distributed non-overlappingly on containers or transport equipment. In this case, an image is directly acquired using a camera or other device, and the contaminated parts are separated using a segmentation method. The total area of ​​all contaminated parts is then calculated. The degree of surface contamination is obtained by dividing the total area of ​​all contaminated parts by the overall area of ​​the image.

[0061] In some embodiments, batches of workpieces are distributed overlappingly on a container or transport equipment. In this case, after acquiring an image using a camera or other device, the container is shaken or the transport equipment is moved for a certain period of time, and then a second image is acquired using a camera or other device. For the two images, the dirty parts are separated using a segmentation method, and the sum of the areas of all dirty parts is calculated. Then, the sum of the areas of all dirty parts is divided by the overall area of ​​the image to obtain the degree of dirtiness of the two surfaces. The average of the sums of the two degrees of dirtiness is taken as the final degree of surface dirtiness.

[0062] In some embodiments, batches of workpieces are overlapped and distributed on a container or transport equipment. In this case, after acquiring an image using a camera or similar device, the container is shaken or the transport equipment is moved for a certain period of time, and a second image is acquired using the same camera or similar device. This process is repeated, and after shaking the container or moving the equipment for a certain period of time, a third or more images are acquired using the same camera or similar device. For multiple images, the contaminated areas are segmented using a segmentation method, and the sum of the areas of all contaminated parts is calculated. Then, the sum of the areas of all contaminated parts is divided by the overall area of ​​the image to obtain multiple degrees of surface contamination. The average of these multiple degrees of surface contamination is taken as the final degree of surface contamination. When batches of workpieces overlap, multiple images are acquired at different times, and the ratio of the contaminated area to the overall area of ​​each image is calculated. The average of these multiple ratios represents the degree of surface contamination of the batch of workpieces, improving the calculation accuracy.

[0063] When determining the required grinding machine workload based on the total hot-dip galvanizing process time and the complexity of the workpiece structure, the following can be used as the basis for determining the grinding machine workload: the total process time multiplied by a first weight, plus the workpiece structure complexity multiplied by a second weight. The larger the basis value, the greater the grinding machine workload. This can be achieved by controlling the workload of the drive equipment in the grinding machine, such as by controlling the speed of the motor.

[0064] Optionally, the first weight is greater than the second weight, and the weight of the total hot-dip galvanizing process time is greater than the weight of the structural complexity of the workpiece itself.

[0065] In this embodiment, optionally, the greater the degree of surface dirt, the longer the required polishing time is determined; conversely, the less dirty the surface, the shorter the required polishing time is determined. During operation, the working intensity of the polishing machine is first determined, then the polishing time is determined, and finally, the polishing machine performs polishing at the determined working intensity throughout the entire working time.

[0066] It should be noted that the polishing machine in this embodiment can be a commercially available polishing machine or the polishing machine in embodiment 2; the preset values, grade values ​​and weights in this embodiment can all be obtained through historical data or experiments, or adjusted based on experience.

[0067] Example 2:

[0068] This embodiment provides a surface polishing system for workpieces after hot-dip galvanizing, including:

[0069] The data acquisition module is configured to: acquire the total hot-dip galvanizing process time of a single workpiece in the batch of workpieces to be polished, the structural type of a single workpiece; and acquire the overall image information of the batch of workpieces.

[0070] The data processing module is configured to determine the structural complexity of a workpiece and the degree of surface contamination of a batch of workpieces based on the structural type and image information of a single workpiece.

[0071] The control requirements determination module is configured to: determine the required grinding machine workload based on the total hot-dip galvanizing process time and the complexity of the workpiece structure; and determine the required grinding time based on the surface contamination level of a batch of workpieces.

[0072] The grinding control module is configured to control the grinding machine to grind the surface of the workpiece under a given working intensity and grinding duration.

[0073] The working method of the system is the same as the surface grinding method of the workpiece after hot-dip galvanizing surface treatment in Example 1, and will not be repeated here.

[0074] Example 3:

[0075] To ensure quality, a significant amount of manpower and resources are required to treat the surface of workpieces after hot-dip galvanizing before final packaging and shipment. Traditionally, each workpiece is manually wiped, which is inefficient; 40% of the workpieces require grinding, a labor-intensive and time-consuming process. After hot-dip galvanizing, the workpieces inevitably become contaminated due to processing, pressing, oiling, and multiple handling processes. Attempts to address appearance issues using cleaning solutions or other efficient methods have not yielded satisfactory results.

[0076] When using automated grinding machines or rust removers for surface polishing, especially for mass production of workpieces, the polishing effect cannot be guaranteed, the polishing time is long, resulting in energy consumption and wasted time.

[0077] In response to the above problems, such as Figure 2 and Figure 6As shown, this embodiment provides a grinding machine, including a working chamber 2 and a turntable disposed within the working chamber 2 via a drive mechanism 3; the drive mechanism 3 is connected to a controller, which is configured to:

[0078] The process involves obtaining the total hot-dip galvanizing process time and structural type of a single workpiece from a batch of workpieces to be polished; and also obtaining the overall image information of the batch of workpieces.

[0079] Based on the structural type and image information of a single workpiece, the complexity of the workpiece structure and the degree of surface contamination of a batch of workpieces are determined respectively;

[0080] The required working intensity of the drive mechanism 3 is determined based on the total hot-dip galvanizing process time and the complexity of the workpiece structure; and the required grinding time is determined based on the degree of surface contamination of the batch of workpieces.

[0081] The drive mechanism 3 is controlled to process the workpiece based on a determined workload and grinding time.

[0082] In this embodiment, the control of the drive mechanism can be achieved by executing the steps of the workpiece surface grinding method after hot-dip galvanizing surface treatment described in Embodiment 1.

[0083] In this embodiment, optionally, the grinding machine includes a frame 1; optionally, the frame 1 is a metal frame structure. At the bottom of the frame 1, a drive mechanism 3 is provided by bolts or welding, optionally, the drive mechanism 3 is a motor; the drive mechanism 3 is connected to a controller.

[0084] The working chamber 2 is mounted on the upper part of the frame 1 by means of bolts or welding. Optionally, the working chamber 2 is a cylindrical structure. It is understood that through holes are provided on the frame 1 and the working chamber 2, and the output shaft of the drive mechanism 3 passes through these through holes.

[0085] The output shaft end of the drive mechanism 3 is connected to the turntable in the middle by welding or bolting. The turntable is located at the bottom of the working chamber 2 and can be set with a gap or rotated with the working chamber 2.

[0086] Specifically, when the drive mechanism 3 rotates, it drives the turntable and the first wire brush 4 on the turntable to rotate; thereby driving the batch of workpieces that have been placed in the working chamber 2 to rotate and perform surface polishing.

[0087] Optionally, a second wire brush 5 is provided on the surface of the turntable and on the inner surface of the working chamber 2; the first wire brush 4 is a cylindrical wire brush.

[0088] Specifically, in the working chamber 2 of the grinding machine, a turntable is set up through the drive mechanism. Not only are steel wire brushes set on the surface of the turntable and the inner surface of the working chamber 2, but a cylindrical steel wire brush is also set in the middle of the turntable. By setting up the steel wire brush, the grinding effect and efficiency can be guaranteed when grinding the surface of the workpiece after hot-dip galvanizing.

[0089] In this embodiment, a feed door 201 is provided above the working chamber 2 via a hinge or the like; when feeding, the feed door 201 is opened, the workpiece to be polished is placed into the working chamber 2, and then the feed door 201 is closed to ensure safety; optionally, two feed doors 201 are symmetrically arranged on the working chamber 2.

[0090] In this embodiment, a discharge door 202 is provided on the side of the working chamber 2 via a hinge or the like; when the working time of the drive mechanism 3 meets the requirements, the discharge door 202 is opened, and the workpiece in the working chamber 2 leaves the working chamber 2 under the action of inertia, thus completing the material handling.

[0091] In this embodiment, the controller, in addition to being connected to the drive mechanism 3, is also connected to multiple cameras, which are respectively set at corresponding positions to acquire images of single or batch workpieces; based on this, the working principle or process of this embodiment is as follows:

[0092] The camera captures overall images of a batch of workpieces to be processed, as well as images of individual workpieces.

[0094] After opening the feed door 201 and loading the workpiece to be processed into the working chamber 2, close the feed door 201; at this time, the discharge door 202 is in the closed state.

[0095] Based on the determined workload and grinding time, the controller controls the drive mechanism 3 to perform workpiece surface grinding.

[0096] After the grinding time is reached, the discharge door 202 is opened, and the workpiece in the working chamber 2 moves out of the working chamber 2 at the opening of the discharge door 202 under the action of inertia; then the drive mechanism 3 is controlled to stop working and the discharge door 202 is closed.

[0097] The grinding machine in this embodiment eliminates the time-consuming and laborious manual grinding or wiping of each piece, thus eliminating the need for three people in the work area; it also solves the safety hazards associated with hand-grinding each workpiece individually, eliminating the opportunity to come into contact with these hazards; compared to manual cleaning of each piece, batch cleaning is used, which increases efficiency by more than 10 times while ensuring quality.
