Description

Technical Field

[0001] This invention relates to the field of ring main unit cabinet conveying control, and particularly to a control method, device, equipment and medium for conveying steel belts. Background Technology

[0002] In the manufacturing process of ring main unit (RNU), multiple cabinet panels are spliced ​​and welded to form the RNU cabinet body. A grinding process is then performed on the cabinet body to polish its edges. After grinding, the cabinet body undergoes an air shower process to remove dust adhering to it. After loading, the cabinet body is moved to the grinding workshop, where it undergoes grinding to minimize the impact of dust generated during the grinding process on the RNU production environment. The cabinet body is then moved from the grinding workshop to the air shower workshop for further air showering to prevent unclean air from re-contaminating the cabinet body.

[0003] Due to the large size of the cabinets, they are currently transported sequentially to the grinding and air shower workshops via conveyor belts. Since the grinding and air shower processes require time, the conveyor belts must wait for the grinding and air shower processes of the cabinets in the grinding and air shower workshops to complete before proceeding. However, the conveyor belt's downtime during cabinet transport is determined by the maximum time required for each process, meaning all cabinets must wait the same amount of time before moving forward, resulting in low transport efficiency. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a control method, device, equipment, and medium for conveying steel belts. By independently handling the loading and unloading of the grinding conveyor belt and the air shower conveyor belt through the grinding retention conveyor belt, the smooth execution of the grinding process and the air shower process is ensured, thereby improving the production efficiency of the ring main unit.

[0005] In a first aspect, embodiments of the present invention provide a control method for a conveyor belt, wherein the conveyor belt comprises a feeding conveyor belt, a grinding conveyor belt, a grinding holding conveyor belt, and an air shower conveyor belt connected in sequence, wherein the feeding conveyor belt, the grinding conveyor belt, and the air shower conveyor belt are used to drive the cabinet to move in a forward rotation, and the grinding holding conveyor belt is used to drive the cabinet to move in a bidirectional direction; the control method for the conveyor belt includes: The feeding conveyor belt sequentially feeds the first cabinet and the second cabinet. The feeding conveyor belt and the grinding conveyor belt move the first cabinet to the grinding and holding conveyor belt. The feeding conveyor belt also moves the second cabinet to the grinding conveyor belt. The cabinet includes the first cabinet and the second cabinet. The first movement time and the first execution time are obtained. When the first movement time is less than or equal to the first execution time, the grinding and holding conveyor belt feeds the first cabinet to the air shower conveyor belt. After the grinding process of the second cabinet is completed, the grinding conveyor belt feeds the second cabinet to the grinding and holding conveyor belt. The first movement time is the time required for the first cabinet to move from the grinding and holding conveyor belt to the air shower conveyor belt, and the first execution time is the time for the second cabinet to undergo the grinding process. Alternatively, when the first movement time is greater than the first execution time, the grinding conveyor belt will transfer the second cabinet that has completed the grinding process to the grinding retention conveyor belt, the grinding retention conveyor belt will feed the first cabinet onto the air shower conveyor belt, the grinding retention conveyor belt will reverse to drive the second cabinet to the beginning of the grinding retention conveyor belt, and the grinding retention conveyor belt will rotate forward to feed the third cabinet, wherein the cabinet includes the third cabinet, and the third cabinet is located after the second cabinet.

[0006] According to some embodiments of the present invention, when the first movement time is less than or equal to the first execution time, the grinding retention conveyor belt feeds the first cabinet to the air shower conveyor belt, the grinding process of the second cabinet is completed, and the grinding conveyor belt feeds the second cabinet to the grinding retention conveyor belt, including: When the first movement time is less than or equal to the first execution time, the state of the air shower conveyor belt is obtained; when the air shower conveyor belt is in an empty state, the first execution time is subtracted from the first movement time to obtain the first time difference. After the grinding and holding conveyor belt stops for the first time difference, the grinding and holding conveyor belt turns towards the air shower conveyor belt to load the first cabinet. When the first cabinet is located on the air shower conveyor belt, the grinding process of the second cabinet is completed, and the grinding conveyor belt turns towards the grinding and holding conveyor belt to load the second cabinet.

[0007] According to some embodiments of the present invention, the conveyor belt further includes a grinding transition conveyor belt, the first end of which is connected to the end of the grinding conveyor belt, and the end of which is connected to the first end of the grinding retention conveyor belt. The grinding transition conveyor belt is used to drive the cabinet to move in a forward rotation. When the first movement time is greater than the first execution time, the grinding conveyor belt transfers the second cabinet, which has completed the grinding process, to the grinding retention conveyor belt. The grinding retention conveyor belt then feeds the first cabinet onto the air shower conveyor belt, including: When the first movement time is greater than the first execution time, the second movement time is obtained. When the second movement time is greater than the difference between the first movement time and the first execution time, the first movement time is subtracted from the sum of the first execution time and the second movement time to obtain the second time difference. The second movement time is the time it takes for the second cabinet to move from the polishing conveyor belt to the polishing transition conveyor belt. The status of the air shower conveyor belt is obtained. When the air shower conveyor belt is empty, the grinding and holding conveyor belt stops for the second time difference. When the second cabinet moves to the grinding transition conveyor belt, the grinding transition conveyor belt and the grinding and holding conveyor belt move synchronously. The grinding transition conveyor belt feeds the second cabinet to the grinding and holding conveyor belt, and the grinding and holding conveyor belt feeds the first cabinet to the air shower conveyor belt.

[0008] According to some embodiments of the present invention, when the first movement time is less than or equal to the first execution time, the grinding and holding conveyor belt feeds the first cabinet onto the air shower conveyor belt, including: When the first movement time is less than or equal to the first execution time, the state of the air shower conveyor belt is obtained. When the air shower conveyor belt is not empty, the second execution time is obtained. The second execution time is the remaining time of the air shower process of the fourth cabinet when the first cabinet is located at the beginning of the grinding and holding conveyor belt. The fourth cabinet is located one position before the first cabinet. The cabinet includes the fourth cabinet. When the second execution time is greater than or equal to the first movement time, the second execution time is subtracted from the first movement time to obtain the third time difference. The grinding and holding conveyor belt stops rotating for the third time difference. The grinding and holding conveyor belt rotates forward to drive the first cabinet to move. The air shower process of the fourth cabinet is completed. When the air shower conveyor belt rotates forward to unload the fourth cabinet, the air shower conveyor belt loads the first cabinet.

[0009] According to some embodiments of the present invention, a first assembly conveyor belt, a second assembly conveyor belt and a third assembly conveyor belt are connected sequentially at the end of the air shower conveyor belt, and the first assembly conveyor belt, the second assembly conveyor belt and the third assembly conveyor belt are all used to drive the cabinet to move in both directions. After the first cabinet is fed from the grinding conveyor belt to the air shower conveyor belt, the following is also included: After the air shower process of the first cabinet is completed, the length of the first cabinet and the first loading length are obtained. When the length of the first cabinet is less than or equal to the first loading length, the air shower conveyor belt, the first assembly conveyor belt and the second assembly conveyor belt drive the first cabinet to move to the beginning of the second assembly conveyor belt, wherein the first loading length is the loading length of the second assembly conveyor belt. Alternatively, when the length of the first cabinet is greater than the first loading length, a second loading length is obtained; when the length of the first cabinet is less than or equal to the second loading length, the first cabinet is driven to move to the beginning of the first assembly conveyor belt, wherein the second loading length is the loading length of the first assembly conveyor belt.

[0010] According to some embodiments of the present invention, after obtaining the length of the first cabinet and the first length to be loaded, the method further includes: When the length of the first cabinet is greater than the length of the second cabinet to be loaded, the second assembly conveyor belt rotates forward to unload the cabinet located on the second assembly conveyor belt to the third assembly conveyor belt; When the second assembly conveyor belt is empty and the third assembly conveyor belt is not fully loaded, the third loading length is obtained. When the length of the cabinet located at the end of the first assembly conveyor belt is less than or equal to the third loading length, the cabinet located at the end of the first assembly conveyor belt is loaded onto the third assembly conveyor belt until the third assembly conveyor belt is fully loaded, and the cabinet located on the first assembly conveyor belt is unloaded onto the second assembly conveyor belt. Alternatively, when the third assembly conveyor belt is fully loaded and the second assembly conveyor belt is not empty or not fully loaded, the second assembly conveyor belt reverses until the cabinet closest to the first assembly conveyor belt moves to the beginning of the second assembly conveyor belt, and the cabinet of the first assembly conveyor belt is unloaded onto the second assembly conveyor belt. When the second assembly conveyor belt is fully loaded and the first assembly conveyor belt is not empty, the first assembly conveyor belt reverses until the cabinet closest to the air shower conveyor belt moves to the beginning of the first assembly conveyor belt.

[0011] According to some embodiments of the present invention, the conveyor belt further includes a feeding and holding conveyor belt, the first end of which is connected to the end of the feeding conveyor belt, and the end of which is connected to the first end of the grinding conveyor belt. The feeding and holding conveyor belt is used to drive the cabinet to move in both directions. The feeding conveyor belt sequentially feeds the first cabinet and the second cabinet. The feeding conveyor belt and the grinding conveyor belt move the first cabinet to the grinding and holding conveyor belt, including: The first cabinet is fed by the feeding conveyor belt. The length of the first cabinet and the fourth length to be fed are obtained. When the length of the first cabinet is less than or equal to the fourth length to be fed, the third execution time and the conveying speed of the feeding conveyor belt are obtained. The third movement time is determined based on the fourth length to be fed and the conveying speed. The fourth length to be fed is the length to be fed on the feeding conveyor belt. The third execution time is the time for the fourth cabinet to perform the grinding process. The fourth cabinet is located one position before the first cabinet. When the third execution time is greater than or equal to the third movement time, the loading and holding conveyor belt reverses to obtain the first cabinet, and the loading and holding conveyor belt rotates forward until the cabinet closest to the grinding conveyor belt moves to the end of the loading and holding conveyor belt. Alternatively, when the third execution time is less than the third movement time, the loading and holding conveyor belt feeds the first cabinet while simultaneously feeding the grinding conveyor belt.

[0012] In a second aspect, embodiments of the present invention provide a control device for conveying steel belts, including at least one control processor and a memory for communicatively connecting to the at least one control processor; the memory stores instructions executable by the at least one control processor, which, when executed by the at least one control processor, enables the at least one control processor to perform the control method for conveying steel belts as described in the first aspect above.

[0013] Thirdly, embodiments of the present invention provide an electronic device including a control device for conveying steel belts as described in the second aspect above.

[0014] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer-executable instructions for performing the control method for conveying steel belts as described in the first aspect above.

[0015] The control method for the conveyor belt according to embodiments of the present invention has at least the following beneficial effects: the conveyor belt includes a feeding conveyor belt, a grinding conveyor belt, a grinding retention conveyor belt, and an air shower conveyor belt connected in sequence; the feeding conveyor belt, the grinding conveyor belt, and the air shower conveyor belt are used to drive the cabinet to move in a forward direction; the grinding retention conveyor belt is used to drive the cabinet to move in a bidirectional direction; the control method for the conveyor belt includes: the feeding conveyor belt sequentially feeding a first cabinet and a second cabinet; the feeding conveyor belt and the grinding conveyor belt conveying the first cabinet to the grinding retention conveyor belt; the feeding conveyor belt conveying the second cabinet to the grinding conveyor belt; wherein the cabinet includes the first cabinet and the second cabinet; acquiring a first movement time and a first execution time; when the first movement time is less than or equal to the first execution time, the grinding retention conveyor belt moves towards the air shower conveyor belt. The first cabinet is fed onto the air shower conveyor belt. After the grinding process of the second cabinet is completed, the grinding conveyor belt feeds the second cabinet onto the grinding retention conveyor belt. The first movement time is the time required for the first cabinet to move from the grinding retention conveyor belt to the air shower conveyor belt, and the first execution time is the time for the second cabinet to undergo the grinding process. Alternatively, if the first movement time is greater than the first execution time, the grinding conveyor belt transfers the second cabinet, which has completed the grinding process, to the grinding retention conveyor belt. The grinding retention conveyor belt feeds the first cabinet onto the air shower conveyor belt. The grinding retention conveyor belt reverses to drive the second cabinet to the beginning of the grinding retention conveyor belt. The grinding retention conveyor belt rotates forward to feed the third cabinet, wherein the cabinet includes the third cabinet, which is located after the second cabinet. According to the technical solution of the present invention, a grinding and holding conveyor belt capable of independent and bidirectional transmission is added. Based on the first motion time and the first execution time, the grinding and holding conveyor belt is controlled to feed or unload materials from the grinding conveyor belt to the air shower conveyor belt. The cabinet that completes the grinding process first is fed to the air shower conveyor belt, or the cabinet that completes the air shower process first is fed to the air shower conveyor belt. The feeding and unloading of the grinding conveyor belt and the air shower conveyor belt are handled independently, thereby ensuring the smooth execution of the grinding process and the smooth execution of the air shower process, and improving the production efficiency of the ring main unit.

[0021] This invention provides a control method, apparatus, equipment, and medium for a conveyor belt. The control method includes: a feeding conveyor belt sequentially feeding a first cabinet and a second cabinet; the feeding conveyor belt and a grinding conveyor belt moving the first cabinet to a grinding and holding conveyor belt; the feeding conveyor belt conveying the second cabinet to the grinding conveyor belt; wherein the cabinet includes the first cabinet and the second cabinet; acquiring a first movement time and a first execution time; when the first movement time is less than or equal to the first execution time, the grinding and holding conveyor belt feeding the first cabinet onto the air shower conveyor belt; after the grinding process of the second cabinet is completed, the grinding conveyor belt feeding the first cabinet onto the grinding and holding conveyor belt. The first movement time is the time required for the first cabinet to move from the grinding and holding conveyor belt to the air shower conveyor belt, and the first execution time is the time for the second cabinet to perform the grinding process; or, when the first movement time is greater than the first execution time, the grinding conveyor belt conveys the second cabinet that has completed the grinding process to the grinding and holding conveyor belt, the grinding and holding conveyor belt feeds the first cabinet onto the air shower conveyor belt, the grinding and holding conveyor belt reverses to drive the second cabinet to the beginning of the grinding and holding conveyor belt, and the grinding and holding conveyor belt rotates forward to feed the third cabinet, wherein the cabinet includes the third cabinet, and the third cabinet is located after the second cabinet. According to the technical solution of the present invention, a grinding and holding conveyor belt capable of independent and bidirectional transmission is added. Based on the first motion time and the first execution time, the grinding and holding conveyor belt is controlled to feed or unload materials from the grinding conveyor belt to the air shower conveyor belt. The cabinet that completes the grinding process first is fed to the air shower conveyor belt, or the cabinet that completes the air shower process first is fed to the air shower conveyor belt. The feeding and unloading of the grinding conveyor belt and the air shower conveyor belt are handled independently, thereby ensuring the smooth execution of the grinding process and the smooth execution of the air shower process, and improving the production efficiency of the ring main unit.

[0022] First, refer to Figure 1 , Figure 1 This is a perspective view of the conveyor belt provided in an embodiment of the present invention.

[0023] like Figure 1 As shown, the conveyor belt in this embodiment includes a feeding conveyor belt 201, a grinding conveyor belt 202, a grinding retention conveyor belt 203, and an air shower conveyor belt 204 connected in sequence. The feeding conveyor belt 201, the grinding conveyor belt 202, and the air shower conveyor belt 204 are used to drive the cabinet 100 to move in a forward rotation, and the grinding retention conveyor belt 203 is used to drive the cabinet 100 to move in a bidirectional direction.

[0024] It should be noted that, due to the large size and weight of the ring main unit 100, and the sharp edges of the unpolished unit 100, if a conventional rubber conveyor belt were used, the sharp edges of the unit 100 would damage the rubber conveyor belt, significantly reducing its service life. Therefore, this application uses a steel conveyor belt, and all conveyor belts are made of metal, which is less prone to wear and thus extends their service life. The feeding conveyor belt 201, polishing conveyor belt 202, polishing retention conveyor belt 203, and air shower conveyor belt 204 in this application are all made of metal.

[0025] It should be noted that both the grinding conveyor belt 202 and the air shower conveyor belt 204 drive the cabinet 100 to move in a forward direction. The forward rotation of the cabinet 100 means that the cabinet 100 moves from the beginning of the conveyor belt to the end of the conveyor belt. The bidirectional rotation of the cabinet 100 means that the conveyor belt can drive the cabinet 100 to move from the beginning of the conveyor belt to the end of the conveyor belt, and it can also drive the cabinet 100 to move from the end of the conveyor belt to the beginning of the conveyor belt.

[0026] It should be noted that the grinding conveyor belt 202 is located at the grinding station. The grinding conveyor belt 202 is used for loading and unloading materials to the grinding station, and the cabinet 100 located at the grinding station performs the grinding process. The air shower conveyor belt 204 is located at the air shower station. The air shower conveyor belt 204 is used for loading and unloading materials to the air shower station, and the cabinet 100 located at the air shower station performs the air shower process.

[0027] Additionally, refer to Figure 1 The conveyor belt also includes a grinding transition conveyor belt 205. The first end of the grinding transition conveyor belt 205 is connected to the end of the grinding conveyor belt 202, and the end of the grinding transition conveyor belt 205 is connected to the first end of the grinding retention conveyor belt 203. The grinding transition conveyor belt 205 is used to drive the cabinet 100 to move in a forward rotation.

[0028] It should be noted that the end of the feeding conveyor belt 201 is connected to the beginning of the grinding conveyor belt 202, the end of the grinding conveyor belt 202 is connected to the beginning of the grinding transition conveyor belt 205, the end of the grinding transition conveyor belt 205 is connected to the beginning of the grinding retention conveyor belt 203, and the end of the grinding retention conveyor belt 203 is connected to the beginning of the air shower conveyor belt 204.

[0029] It should be noted that the grinding transition conveyor belt 205 remains in operation, and the cabinet 100 does not stop on the grinding transition conveyor belt 205. The grinding transition conveyor belt 205 is used to extend the time for the cabinet 100 to move to the air shower conveyor belt 204 after the grinding process is completed, so as to avoid the air shower station from being blocked.

[0030] Additionally, refer to Figure 1At the end of the air shower conveyor belt 204, there are a first assembly conveyor belt 206, a second assembly conveyor belt 207 and a third assembly conveyor belt 208 connected in sequence. The first assembly conveyor belt 206, the second assembly conveyor belt 207 and the third assembly conveyor belt 208 are all used to drive the cabinet 100 to move in both directions.

[0031] It should be noted that the first assembly conveyor belt 206, the second assembly conveyor belt 207, and the third assembly conveyor belt 208 are located in the assembly area to provide placement space for the cabinet 100 that has completed the air shower process, and to move the cabinet 100 located on the first assembly conveyor belt 206, the second assembly conveyor belt 207, or the third assembly conveyor belt 208 to the shipping area by manual handling or automated equipment. Since the movement takes a certain amount of time, the first assembly conveyor belt 206, the second assembly conveyor belt 207, and the third assembly conveyor belt 208 are set with a length greater than the other conveyor belts to avoid the failure of the air shower conveyor belt 204 to unload materials.

[0032] It should be noted that an air shower transition conveyor belt is also provided between the air shower conveyor belt 204 and the first assembly conveyor belt 206. The end of the air shower conveyor belt 204 is connected to the beginning of the air shower transition conveyor belt, the end of the air shower transition conveyor belt is connected to the beginning of the first assembly conveyor belt 206, the end of the first assembly conveyor belt 206 is connected to the beginning of the second assembly conveyor belt 207, and the end of the second assembly conveyor belt 207 is connected to the beginning of the third assembly conveyor belt 208.

[0033] It should be noted that the air shower transition conveyor belt remains in operation, and the cabinet 100 does not stop on the air shower transition conveyor belt. The air shower transition conveyor belt is used to extend the time for the cabinet 100 to move to the first assembly conveyor belt 206 after completing the air shower process, so as to provide operation time for the first assembly conveyor belt 206, the second assembly conveyor belt 207, or the third assembly conveyor belt 208 to unload the cabinet 100, and to prevent the air shower station from being blocked due to the first assembly conveyor belt 206, the second assembly conveyor belt 207, and the third assembly conveyor belt 208 being fully loaded, which would prevent the air shower conveyor belt 204 from unloading materials.

[0034] Additionally, refer to Figure 1 The conveyor belt also includes a loading and holding conveyor belt 209. The first end of the loading and holding conveyor belt 209 is connected to the end of the loading conveyor belt 201, and the end of the loading and holding conveyor belt 209 is connected to the first end of the grinding conveyor belt 202. The loading and holding conveyor belt 209 is used to drive the cabinet 100 to move in both directions.

[0035] It should be noted that the feeding conveyor belt 201 can only feed in the forward direction. In order to ensure that there are enough cabinets 100 to feed to the grinding conveyor belt 202 and to prevent the grinding station from being blocked, a feeding retention conveyor belt 209 is set between the feeding conveyor belt 201 and the grinding conveyor belt 202. Both the feeding retention conveyor belt 209 and the grinding retention conveyor belt 203 must ensure that they can load the maximum number of cabinets 100.

[0036] It should be noted that the feeding conveyor belt 201, the feeding holding conveyor belt 209, the grinding conveyor belt 202, the grinding transition conveyor belt 205, the grinding holding conveyor belt 203, the air shower conveyor belt 204, the air shower transition conveyor belt, the first assembly conveyor belt 206, the second assembly conveyor belt 207, and the third assembly conveyor belt 208 can all stop rotating, and each can independently rotate forward, reverse, or stop rotating.

[0037] The following is based on Figure 1 The conveyor belt shown further illustrates the technical solution of this embodiment of the invention.

[0038] Reference Figure 2 , Figure 2 This is a flowchart of a control method for a conveyor belt provided in an embodiment of the present invention. The control method for the conveyor belt includes, but is not limited to, the following steps: S10, the feeding conveyor belt sequentially feeds the first cabinet and the second cabinet. The feeding conveyor belt and the grinding conveyor belt move the first cabinet to the grinding and holding conveyor belt. The feeding conveyor belt then transports the second cabinet to the grinding conveyor belt. The cabinet includes the first cabinet and the second cabinet.

[0039] It should be noted that the second cabinet is located after the first cabinet. For any cabinet, after the loading conveyor belt rotates forward to load the cabinet, it rotates forward to unload the cabinet to the grinding conveyor belt. When the grinding conveyor belt loads the cabinet to the grinding station, it performs the grinding process on the cabinet. When the grinding process is completed, the grinding conveyor belt unloads the cabinet to the grinding station conveyor belt.

[0040] S20, obtain the first movement time and the first execution time. When the first movement time is less than or equal to the first execution time, the grinding retention conveyor belt feeds the first cabinet to the air shower conveyor belt. After the grinding process of the second cabinet is completed, the grinding conveyor belt feeds the second cabinet to the grinding retention conveyor belt. The first movement time is the time required for the first cabinet to move from the grinding retention conveyor belt to the air shower conveyor belt, and the first execution time is the time for the second cabinet to perform the grinding process.

[0041] It should be noted that when the first movement time is less than or equal to the first execution time, that is, when the grinding process of the second cabinet is completed or before it is completed, the first cabinet has already moved to the air shower conveyor belt. At this time, in order to ensure the continuous working state of the air shower station, the grinding and holding conveyor belt rotates forward to unload the first cabinet and load the first cabinet onto the air shower conveyor belt so that the first cabinet can perform the air shower process.

[0042] It should be noted that after the grinding process of the second cabinet is completed, the grinding conveyor rotates forward to unload the second cabinet and loads it onto the grinding retention conveyor belt. This ensures that the air shower conveyor belt is not empty, and that the grinding retention conveyor belt has at least one cabinet, keeping the air shower station in operation and thus improving the production efficiency of the cabinets.

[0043] S30, or, when the first movement time is greater than the first execution time, the grinding conveyor belt will transfer the second cabinet that has completed the grinding process to the grinding retention conveyor belt, the grinding retention conveyor belt will feed the first cabinet onto the air shower conveyor belt, the grinding retention conveyor belt will reverse to drive the second cabinet to the beginning of the grinding retention conveyor belt, and the grinding retention conveyor belt will rotate forward to feed the third cabinet, wherein the cabinet includes the third cabinet, and the third cabinet is located after the second cabinet.

[0044] It should be noted that when the first movement time is greater than the first execution time, that is, when the grinding process of the second cabinet is completed, the first cabinet has not yet moved to the air shower conveyor belt, meaning the first cabinet is still located on the grinding hold conveyor belt. At this time, to maintain the working state of the grinding station, the second cabinet needs to be unloaded from the grinding conveyor belt as soon as possible. The grinding conveyor belt unloads the second cabinet and then loads it onto the grinding hold conveyor belt. At this time, the grinding hold conveyor belt contains both the first and second cabinets. To ensure the working state of the air shower station, the grinding hold conveyor belt rotates clockwise so that both the first and second cabinets move towards the air shower conveyor belt. When the air shower conveyor belt is empty, it is promptly loaded to maintain its working state. After the air shower conveyor belt is loaded, the second cabinet is located at the end of the grinding and holding conveyor belt. In order to carry as many cabinets as possible on the grinding and holding conveyor belt so that the air shower station and the grinding station can remain in working condition, the grinding and holding conveyor belt is reversed so that the second cabinet is located at the beginning of the grinding and holding conveyor belt. The third cabinet is loaded on the grinding and holding conveyor belt, so that there is a preset workpiece gap between the second cabinet and the third cabinet, which can carry the maximum number of cabinets while preventing cabinet collisions.

[0045] In another embodiment, step S20 includes, but is not limited to, the following steps: S201, when the first motion time is less than or equal to the first execution time, obtain the state of the air shower conveyor belt; when the air shower conveyor belt is in an empty state, subtract the first motion time from the first execution time to obtain the first time difference. S202, after the first time difference when the grinding and holding conveyor belt stops, the grinding and holding conveyor belt turns forward to the air shower conveyor belt to load the first cabinet. When the first cabinet is on the air shower conveyor belt, the grinding process of the second cabinet is completed, and the grinding conveyor belt turns forward to the grinding and holding conveyor belt to load the second cabinet.

[0046] It should be noted that when the air shower conveyor belt is empty, it is necessary to ensure that subsequent air shower conveyor belts do not stop working due to loading failure. If materials are directly loaded onto the air shower conveyor belt, subsequent air shower conveyor belts will have to wait for the next cabinet to complete its grinding process before entering the air shower conveyor belt, resulting in unnecessary time waste. Therefore, to ensure that there are always cabinets on the grinding and holding conveyor belt and to maintain smooth operation of the air shower station, the grinding and holding conveyor belt is controlled to stop rotating. This ensures that the second cabinet is on the grinding and holding conveyor belt waiting to enter the air shower process before the first cabinet's air shower process is completed. In this case, after the air shower conveyor belt unloads materials, the idle time of the air shower conveyor belt is greatly shortened, thereby improving the smoothness of the air shower station's operation.

[0047] It should be noted that since the time required for the air shower process is necessarily greater than the movement time, the second cabinet arrives at the grinding and holding conveyor belt before the air shower process is completed. This ensures that the air shower conveyor belt immediately loads the second cabinet after the first cabinet is unloaded, thus maintaining the smooth operation of the air shower station.

[0048] In another embodiment, in step S30, when the first movement time is greater than the first execution time, the grinding conveyor belt transfers the second cabinet that has completed the grinding process to the grinding retention conveyor belt, and the grinding retention conveyor belt feeds the first cabinet onto the air shower conveyor belt, including but not limited to the following steps: S301, when the first movement time is greater than the first execution time, the second movement time is obtained; when the second movement time is greater than the difference between the first movement time and the first execution time, the first movement time is subtracted from the sum of the first execution time and the second movement time to obtain the second time difference, wherein the second movement time is the time for the second cabinet to move from the grinding conveyor belt to the grinding transition conveyor belt. S302, obtain the status of the air shower conveyor belt. When the air shower conveyor belt is empty, the grinding and holding conveyor belt stops for a second time difference. When the second cabinet moves to the grinding transition conveyor belt, the grinding transition conveyor belt and the grinding and holding conveyor belt move synchronously. The grinding transition conveyor belt feeds the second cabinet to the grinding and holding conveyor belt, and the grinding and holding conveyor belt feeds the first cabinet to the air shower conveyor belt.

[0049] It should be noted that when the second cabinet moves to the grinding transition conveyor belt, the first cabinet and the second cabinet maintain a preset workpiece gap, and ensure that there is at least one cabinet on the grinding conveyor belt to ensure the smooth operation of the air shower station.

[0050] It should be noted that when the second movement time is greater than the difference between the first movement time and the first execution time, that is, the time when the grinding and holding conveyor belt is in an unloaded state is the second time difference, the grinding and holding conveyor belt is controlled to stop, so that there is at least one cabinet on the grinding and holding conveyor belt.

[0051] In another embodiment, in step S20, when the first movement time is less than or equal to the first execution time, the grinding and holding conveyor belt feeds the first cabinet onto the air shower conveyor belt, including but not limited to the following steps: S203, when the first movement time is less than or equal to the first execution time, obtain the state of the air shower conveyor belt; when the air shower conveyor belt is not empty, obtain the second execution time, wherein the second execution time is the remaining time of the air shower process of the fourth cabinet when the first cabinet is located at the beginning of the grinding and stagnant conveyor belt, the fourth cabinet is located one position before the first cabinet, and the cabinet includes the fourth cabinet. S204, when the second execution time is greater than or equal to the first motion time, the second execution time is subtracted from the first motion time to obtain the third time difference. The grinding and holding conveyor belt stops rotating for the third time difference. The grinding and holding conveyor belt rotates forward to drive the first cabinet to move. The air shower process of the fourth cabinet is completed. When the air shower conveyor belt rotates forward to unload the fourth cabinet, the air shower conveyor belt loads the first cabinet.

[0052] It should be noted that since the air shower workshop is a closed system, the gate of the air shower workshop needs to be opened or closed when the cabinet enters or exits the air shower conveyor belt. After determining the third time difference, the third time difference of the grinding and stagnant conveyor belt is controlled so that the first cabinet is loaded at the same time as the fourth cabinet is unloaded by the air shower conveyor belt. In other words, the time required for the air shower conveyor to open and close one gate is reduced, thereby further improving the production efficiency of the ring main unit.

[0053] In another embodiment, after the grinding conveyor belt feeds the first cabinet onto the air shower conveyor belt in step S20 or step S30, the following steps are included, but are not limited to: S205, the air shower process of the first cabinet is completed, and the length of the first cabinet and the first loading length are obtained. When the length of the first cabinet is less than or equal to the first loading length, the air shower conveyor belt, the first assembly conveyor belt and the second assembly conveyor belt drive the first cabinet to move to the beginning of the second assembly conveyor belt. The first loading length is the loading length of the second assembly conveyor belt. S206, or, when the length of the first cabinet is greater than the first loading length, obtain the second loading length; when the length of the first cabinet is less than or equal to the second loading length, drive the first cabinet to move to the beginning of the first assembly conveyor belt, wherein the second loading length is the loading length of the first assembly conveyor belt.

[0054] It should be noted that after the air shower process is completed, the first cabinet is prioritized for unloading onto the second assembly conveyor belt to prevent unloading failure when the first assembly conveyor belt is fully loaded. However, when the second assembly conveyor belt is fully loaded, the first cabinet is unloaded to the end of the first assembly conveyor belt, maintaining a preset workpiece gap between the cabinets.

[0055] It should be noted that the length to be loaded is the unloaded length of the assembly conveyor belt minus the preset workpiece gap length.

[0056] In another embodiment, after obtaining the length of the first cabinet and the first length to be loaded in step S205, the following steps are included, but are not limited to: S2051, when the length of the first cabinet is greater than the length of the second cabinet to be loaded, the second assembly conveyor belt rotates forward to unload the cabinet located on the second assembly conveyor belt to the third assembly conveyor belt. S2052, when the second assembly conveyor belt is empty and the third assembly conveyor belt is not fully loaded, obtain the third loading length. When the length of the cabinet at the end of the first assembly conveyor belt is less than or equal to the third loading length, load the cabinet at the end of the first assembly conveyor belt to the third assembly conveyor belt until the third assembly conveyor belt is fully loaded, unload the cabinet at the first assembly conveyor belt to the second assembly conveyor belt. S2053, or, when the third assembly conveyor belt is fully loaded and the second assembly conveyor belt is not empty or not fully loaded, the second assembly conveyor belt reverses until the cabinet closest to the first assembly conveyor belt moves to the beginning of the second assembly conveyor belt, and the cabinets of the first assembly conveyor belt are unloaded onto the second assembly conveyor belt. When the second assembly conveyor belt is fully loaded and the first assembly conveyor belt is not empty, the first assembly conveyor belt reverses until the cabinet closest to the air shower conveyor belt moves to the beginning of the first assembly conveyor belt.

[0057] It should be noted that when the length of the first cabinet is greater than the length of the second cabinet to be loaded, that is, when both the first and second assembly conveyors are fully loaded, the cabinets on the second assembly conveyor will be unloaded one by one, and the second assembly conveyor will load the cabinets onto the third assembly conveyor.

[0058] It should be noted that after all the cabinets on the second assembly conveyor belt are unloaded to the third assembly conveyor belt, the third assembly conveyor belt is still not fully loaded. In order to load the third assembly conveyor belt with the maximum number of cabinets, the cabinets located on the first assembly conveyor belt are transferred to the third assembly conveyor belt one by one until the third assembly conveyor belt is fully loaded. Then, the cabinets located on the first assembly conveyor belt are unloaded one by one, and the first assembly conveyor belt feeds the second assembly conveyor belt.

[0059] It should be noted that when the third assembly conveyor belt is fully loaded, the second assembly conveyor belt is still loaded with cabinets. To ensure the second assembly conveyor belt can carry the maximum number of cabinets, it is reversed, so that there is a preset workpiece gap between the cabinets when they are loaded from the first assembly conveyor belt. When the second assembly conveyor belt is fully loaded, the first assembly conveyor belt is either empty or partially loaded. When the first assembly conveyor belt is empty, the air shower conveyor belt unloads the cabinets that have completed the air shower process onto the first assembly conveyor belt. The first assembly conveyor belt maintains a preset workpiece gap between all cabinets, and the cabinet closest to the air shower conveyor belt is located at the beginning of the first assembly conveyor belt. When the first assembly conveyor belt is partially loaded, it is reversed, so that there is a preset workpiece gap between the cabinets when they are loaded from the air shower conveyor belt, and it ensures that the first assembly conveyor belt can carry the maximum number of cabinets.

[0060] It should be noted that when the third assembly conveyor belt is fully loaded, the second assembly conveyor belt is empty. The first assembly conveyor belt unloads cabinets one by one and then loads cabinets onto the second assembly conveyor belt until the first assembly conveyor belt is empty or the second assembly conveyor belt is fully loaded. When the first assembly conveyor belt is empty, the air shower conveyor belt unloads cabinets that have completed the air shower process onto the first assembly conveyor belt. The first assembly conveyor belt maintains a preset workpiece gap between all cabinets, and the cabinet closest to the air shower conveyor belt is located at the beginning of the first assembly conveyor belt.

[0061] In another embodiment, in step S10, the feeding conveyor belt sequentially feeds the first cabinet and the second cabinet, and the feeding conveyor belt and the grinding conveyor belt move the first cabinet to the grinding and holding conveyor belt, including but not limited to the following steps: S101, the feeding conveyor belt feeds the first cabinet, obtains the length of the first cabinet and the fourth length to be fed, when the length of the first cabinet is less than or equal to the fourth length to be fed, obtains the third execution time and the conveying speed of the feeding conveyor belt, and determines the third movement time based on the fourth length to be fed and the conveying speed, wherein the fourth length to be fed is the length to be fed on the feeding conveyor belt, the third execution time is the time for the fourth cabinet to perform the grinding process, and the fourth cabinet is located one position before the first cabinet; S102, when the third execution time is greater than or equal to the third movement time, the loading and holding conveyor belt reverses to obtain the first cabinet, and the loading and holding conveyor belt rotates forward until the cabinet closest to the grinding conveyor belt moves to the end of the loading and holding conveyor belt. S103, or, when the third execution time is less than the third motion time, the loading and holding conveyor belt feeds the first cabinet while feeding the grinding conveyor belt.

[0062] It should be noted that when the length of the first cabinet is less than or equal to the fourth loading length, that is, the loading and holding conveyor belt can load the first cabinet; the third movement time is the time required for the loading and holding conveyor belt to load the first cabinet after loading the first cabinet and then turning to the grinding conveyor belt to load the next cabinet. Based on the length of the first cabinet, the length that the loading and holding conveyor belt needs to convey can be determined. The third movement time is obtained by dividing the length that needs to be conveyed by the speed of the loading and holding conveyor belt.

[0063] It should be noted that when the third execution time is greater than or equal to the third movement time, i.e., when the first cabinet is loaded onto the loading conveyor belt and the grinding conveyor belt is turning forward to load the first cabinet, the grinding process of the fourth cabinet is either just completed or the grinding process of the fourth cabinet has not yet ended. In this case, loading the first cabinet onto the loading conveyor belt will not affect the loading of the grinding conveyor belt, and the grinding station can still maintain its working state. The loading conveyor belt reverses to obtain the first cabinet. There is a preset workpiece gap between the cabinets located on the loading conveyor belt. The loading conveyor belt rotates forward until the cabinet closest to the grinding conveyor belt moves to the end of the loading conveyor belt. This ensures that the grinding conveyor belt can be loaded in a timely manner when it unloads, maintaining the smoothness of the grinding station.

[0064] It should be noted that when the third execution time is less than the third movement time, that is, if the loading and holding conveyor belt prioritizes loading the first cabinet, the grinding conveyor belt will be empty after the grinding conveyor belt unloads the fourth cabinet, and the loading and holding conveyor belt will not be able to load the grinding conveyor belt in time. Therefore, after the grinding conveyor belt unloads the fourth cabinet, the loading and holding conveyor belt will prioritize loading the grinding conveyor belt, and then load the first cabinet.
