DETAILED DESCRIPTION

[0078] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of the present invention.

[0079] In terms of material flow, a large number of semi-finished products need to be stored off the production line and then shipped out for distribution and transported between processes during the subsequent production process. These frequent and complex logistics transfers not only consume significant labor costs but also lead to low overall production efficiency. Furthermore, due to the uncontrollable factors of manual operation, operational safety accidents frequently occur, posing a significant risk to the company's production safety.

[0080] More seriously, traditional material transfer methods suffer from inefficiencies and low accuracy in the raw material receiving process. This is primarily due to manual errors and fatigue, which can result in inconsistent quantities or substandard quality of raw materials upon arrival. Furthermore, while some processes in the inter-process transfer of semi-finished and finished products have been automated, manual handling still accounts for a significant portion. This not only reduces the degree of automation but also leads to inefficient manual handling, increased working hours, and greater labor intensity. More critically, manual handling is prone to delivery errors, causing significant inconvenience and losses in subsequent production.

[0081] In summary, the existing material storage and transfer systems and methods in electric drive workshops can no longer meet the current automotive parts industry's demand for efficient, accurate and safe production.

[0082] Based on this, the utility model provides a material transfer system for an electric drive workshop, see Figure 1 The material transfer system 100 provided by the present invention includes:

[0083] Scheduling control equipment 110, at least one production line 120 selected from the group consisting of a shell processing line, a shell sorting line, a shell stator subassembly line, an electric drive main assembly line, and a finished product quality inspection line, shelves 130 arranged in storage areas corresponding to each target material, and robots 140 corresponding to each target material. The target materials include materials required by all production lines and output materials.

[0084] Each shelf 130 is provided with a storage portion for holding target materials corresponding to the storage area to which it belongs;

[0085] Each robot 140 includes an actuator for transporting a corresponding target material, and each robot 140 is disposed between a corresponding upstream point and a corresponding downstream point.

[0086] Among them, the upstream point corresponding to the robot 140 is the storage area corresponding to the same target material as the robot 140, or the offline workstation of the production line that outputs the target material corresponding to the robot 140; the downstream point corresponding to the robot 140 is the online workstation of the production line that requires the target material corresponding to the robot 140, or the storage area corresponding to the same target material as the robot 140.

[0087] Each production line 120 includes a loading section provided at an upstream station, an unloading section provided at a downstream station, and a dispatching terminal.

[0088] The scheduling control device 110 is communicatively connected to the scheduling terminals of each robot 140 and each production line 120 .

[0089] This embodiment enables the electric drive workshop's material transfer system to achieve highly automated and intelligent material transfer by integrating scheduling and control equipment, multiple production lines (including a housing processing line, a housing sorting line, a housing stator assembly line, an electric drive main assembly line, and a finished product quality inspection line), dedicated storage areas and shelves for target materials, and dedicated robots for each material. Each shelf in the system is designed specifically for its corresponding material, ensuring orderly storage and rapid access. The robots, equipped with actuators, precisely handle materials. Flexible upstream and downstream positioning allows them to retrieve materials from the storage area and deliver them to the required production line, as well as retrieve materials from offline workstations and return them to the storage area, significantly improving the efficiency and flexibility of material flow. Furthermore, the loading and unloading sections and dispatching terminals on each production line communicate closely with the scheduling and control equipment, enabling real-time monitoring and precise scheduling of the entire material flow process. This system not only significantly reduces the complexity of material management, but also improves its accuracy and responsiveness, thereby increasing the efficiency of material transfer. Furthermore, material transfer can be performed without human intervention, ensuring the safety of logistics and effectively reducing labor costs.

[0090] In order to more clearly illustrate the shelf robot in the present invention, the following will be described in detail with reference to the accompanying drawings. Figure 2a 、 Figure 2b 、 Figure 3a 、 Figure 3b 、 Figure 4a 、 Figure 4b as well as Figure 4c Specifically, the shelf 130 includes multiple shelves including a first shelf 1, a second shelf 2 and a third shelf 3.

[0091] The robots 140 include various robots including a lurking robot 5 , a forklift robot 6 , and a container robot 7 .

[0092] The first shelf 1 and the latent robot 5 have the same target material, and the latent robot 5 is provided with a first execution part 51, and the first shelf 1 is provided with a support part 11. The first execution part 51 and the support part 11 are used to cooperate with each other to enable the latent robot 5 to lift or put down the first shelf 1. Figure 2a In the figure, the upper figure is a top view of the lurking robot 5 holding up the first shelf 1, and the lower figure is a front view of the lurking robot 5.

[0093] The target materials corresponding to the second shelf 2 and the forklift robot 6 are the same, and the second shelf 2 is provided with multiple storage platforms 21 in sequence along the vertical direction. The forklift robot 6 is provided with a first lifting mechanism 61 and a second execution part 62. The first lifting mechanism 61 is used to drive the second execution part 62 to move in the vertical direction so that the second execution part 62 forks the materials placed on the storage platform 21, or the second execution part 62 places the forked materials on the storage platform 21. Figure 3b In the figure, the left picture is a front view of the second shelf 2, and the right picture is a left view of the second shelf 2.

[0094] The third shelf 3 has the same target material as the corresponding material box robot 7, and the third shelf 3 is provided with multiple material boxes 31 in sequence along the vertical direction. The material box robot 7 is provided with a second lifting mechanism 71 and a third execution part 72. The second lifting mechanism 71 is used to drive the third execution part 72 to move in the vertical direction. The third execution part 72 and the material box 31 are used to cooperate with each other to transfer the material box 31 to the material box robot 7, or to place the material box carried by the material box robot 7 on the third shelf 3. Figure 4b This is a schematic diagram of the third shelf 3. During the material transfer process, when entering the warehouse, the material box robot 7 obtains multiple material boxes from the conveyor line, and then places the multiple material boxes on the third shelf 3 for storage of the material box materials. When leaving the warehouse, the material box robot 7 obtains multiple material boxes from the third shelf 3, and then places the multiple material boxes to the production line or storage area.

[0095] In a possible embodiment, since the number of boxes stored by the box robot is limited and it is not suitable for long-distance delivery, the efficiency is low. In order to improve the efficiency of material transfer, the shelf 130 also includes a fourth shelf 4, see Figure 4c The fourth shelf 4 includes multiple storage layers 41. After the material box robot 7 obtains the material box from the third shelf 3, it can first place the material box on the fourth shelf 4, and the lurking robot 5 will deliver the material box on the fourth shelf 4 to the production line or storage area. Figure 4c In the figure, the left picture is a left view of the fourth shelf 4, the upper right corner is a front view of the fourth shelf 4, and the lower right corner is a top view of the fourth shelf 4.

[0096] The above-mentioned embodiments significantly enhance the flexibility and efficiency of material management by introducing a diverse combination of shelves and robots. Specifically, the system includes a first shelf that works in conjunction with a hidden robot. The hidden robot's first actuator works in concert with the first shelf's support, enabling easy lifting and lowering of the shelf and facilitating rapid material movement. The second shelf is combined with a forklift robot, which, through the forklift robot's first lifting mechanism and second actuator, can precisely pick up and move materials placed on multiple storage platforms, improving material access flexibility and space utilization. The third shelf is designed with a bin robot, utilizing the bin robot's second lifting mechanism and third actuator to achieve close coordination with the bins. Whether removing a bin from a shelf or placing it on the shelf, efficient and stable automated operations are achieved. This integrated configuration of multiple shelves and robots optimizes material flow paths, saves material storage space, reduces manual intervention, and enables rapid, accurate, and safe material transfer between different storage areas and production lines. This reduces labor costs and significantly improves the efficiency and accuracy of material transfer, thereby reducing the complexity of material management and improving production efficiency.

[0097] In order to more clearly explain the electric drive workshop material transfer system provided by the present invention, the following will take the production line including the shell processing line, shell sorting line, shell stator subassembly line, electric drive main assembly line and finished product quality inspection line as an example, combined with Figure 5 and Figure 6 A detailed demonstration of how the system can realize material transfer in the electric drive workshop is given in detail. For the convenience of description, Figure 5 Only the receiving dock, storage area, robots, production lines, docking points, and elevators are shown:

[0098] S601: When the supplier receives the materials, the truck arrives at the platform to receive the goods. The human sends the empty shelf replenishment instruction to the robot through the terminal device, and the robot transfers the empty shelves from the warehouse area to the receiving area docking point.

[0099] S602: The forklift robot picks up the incoming shelf from the delivery vehicle and places it on an empty shelf at the docking point, triggering a warehousing instruction.

[0100] In S603, the robot system receives the material information and stores the material in the corresponding storage area according to the material attributes. The robot is dispatched to transfer the full shelves to the corresponding storage area to update the inventory.

[0101] Among them, the materials provided by suppliers include large parts and small standard parts. Large parts can be housing blanks, shaft gear blanks, shaft gear semi-finished products, etc., and small standard parts can be wiring harness assemblies, oil coolers, breather plug sub-assemblies, etc.

[0102] The warehouse area includes a flat warehouse (i.e. the first storage area, the fifth storage area, the sixth storage area and the eighth storage area with the first shelf hereinafter), a forklift garage (i.e. the second storage area, the third storage area and the seventh storage area with the second shelf hereinafter) and a material box vertical warehouse (i.e. the fourth storage area and the ninth storage area with the third shelf hereinafter).

[0103] The aforementioned receiving platform 510 is set in the material transfer system. The receiving platform 510 transfers the incoming materials from the supplier to the eighth storage area 512 through the seventh latent robot 511, and stores them on the first shelf set in the eighth storage area 512, that is, the eighth storage area 512 is used to store shell blanks.

[0104] The receiving platform 510 can also transfer the assembly parts to the ninth storage area 5274 through the second container robot 5276 and store them on the third shelf set in the ninth storage area 5274.

[0105] Taking the case of processing and manufacturing shells as an example, the seventh latent robot 511 first transfers the empty shelves from the eighth storage area 512 to the docking point set between the receiving platform 510 and the eighth storage area 512. The forklift robot picks up the raw materials from the shipping station of the receiving platform 510 and brings them to the docking point. The seventh latent robot 511 then transfers the raw materials to the eighth storage area 512 for storage. The principle of the method for transferring empty shelves at other locations in this article is the same as the principle of the above method. Figure 5 For the sake of convenience in description, the connection points between the receiving platform 510 and the eighth storage area 512 are not shown.

[0106] If the incoming materials are for processing and manufacturing other products, the corresponding storage area will be selected according to the properties of the incoming materials. When entering and leaving the warehouse, robots corresponding to the storage area will be used for transportation. I will not go into details here.

[0107] This embodiment effectively improves the automation and efficiency of material warehousing by adding a receiving platform and specifically deploying the first and third shelves, as well as the seventh lurker robot and the second bin robot, in the storage areas for housing blanks and assembly parts, respectively. The seventh lurker robot and the second bin robot are responsible for quickly and accurately transferring housing blanks and assembly parts from the receiving platform to their corresponding storage areas, reducing manual handling and accelerating material turnover, providing stable and efficient material support for continuous production in the electric drive workshop.

[0108] S604, when the shell processing line's online station triggers a material call demand, the production line or manual triggers the shell blank part's delivery and online instruction.

[0109] In step S605, the robot system receives the outbound instruction, allocates inventory, and issues the task of taking the shell blank out of the warehouse and off the shelf. The robot transfers the shell blank to the online station of the shell processing line.

[0110] S606, the shell processing line performs processing. After the processing is completed, the production line or the manual terminal triggers the shell semi-finished product offline storage instruction.

[0111] S607, the robot system receives the instruction, allocates a storage location in the incoming warehouse area, and dispatches the robot to transfer the semi-finished shell product to an empty storage location in the target warehouse area for storage.

[0112] Steps S604-S607 involve transferring the shell blanks stored in first storage area 512 to shell processing line 514. First storage area 512 is used to store shell blanks, sharing the same function as the aforementioned eighth storage area. Therefore, the first and eighth storage areas can be the same or different. For ease of description, both are labeled as storage area 512. Similarly, the second and third storage areas are designated as storage area 518, the fifth and sixth storage areas are designated as 529, and the fourth and ninth storage areas are designated as storage area 5274.

[0113] In one possible embodiment, a counter can be installed in the production line. When the production line processes a certain number of shell blanks, it will trigger the instruction to ship a new batch of shell blanks online. In another possible embodiment, a terminal device can be installed in the production line, and staff can use this terminal device to trigger the instruction to ship the shell blanks online. This is not specifically limited here.

[0114] The shell processing line 514 includes a loading section and a unloading section.

[0115] The loading part of the shell processing line 514 is used to cooperate with the first execution part of the first latent robot 513 to transfer the materials placed on the first shelf lifted by the first latent robot 513 to the shell processing line for processing to obtain semi-finished shell products.

[0116] The first latent robot 513 is disposed between the first storage area 512 and the on-line station of the shell processing line 514 .

[0117] After the shell blank is processed by the shell processing line 514 to obtain the shell semi-finished product, the unloading part of the shell processing line cooperates with the second execution part of the first forklift robot 517 so that the second execution part forks the shell semi-finished product obtained by the shell processing line 514.

[0118] The first forklift robot 517 is disposed between the downstream station of the shell processing line 514 and the second storage area 518 .

[0119] This embodiment integrates the collaborative operation of the shell processing line, the lurking robot, and the forklift robot, achieving highly automated and efficient material handling. Specifically, the first lurking robot is positioned between the first storage area and the shell processing line's loading station, while the first forklift robot is positioned between the shell processing line's loading station and the second storage area. This effectively shortens the material transfer distance from storage to the processing line and then to the finished product before leaving the processing line, significantly improving material transfer efficiency. This eliminates the need for human intervention, reduces potential damage during material transfer, and ensures the integrity and quality stability of the resulting electric drive products.

[0120] In a possible embodiment, the semi-finished shell product can be directly transferred to the second storage area 518 by the first forklift robot 517 .

[0121] In order to improve the transfer efficiency and thus improve the production efficiency of the electric drive, in another possible embodiment, a second latent robot 515 can be set between the offline station of the shell processing line and the first docking point 516. The first docking point 516 is located between the offline station of the shell processing line 514 and the second storage area 518. The system is provided with a first shelf at the first docking point 516.

[0122] During the transfer process of the shell semi-finished product, the unloading part of the shell processing line 514 can cooperate with the first execution part of the second latent robot 515 to place the shell semi-finished product on the first shelf supported by the second latent robot 515, and the second latent robot 515 transfers the shell semi-finished product to the first docking point, and then the first forklift robot 517 set between the first docking point 516 and the second storage area 518 transfers the shell semi-finished product at the first docking point 516 to the second storage area 518.

[0123] This embodiment introduces a second lurking robot positioned between the shell processing line's off-line station and the first docking point, enabling the shell processing line's material handling department to accurately place the processed semi-finished shells on the shelf held up by the second lurking robot, thus achieving a seamless transition from the processing line to the storage area. Furthermore, the first forklift robot is deployed between the first docking point and the second storage area, further accelerating the transfer of materials from the docking point to the storage area and ensuring the smoothness and efficiency of the entire production logistics system. This series of designs not only reduces manual intervention and operating costs, but also effectively improves the flexibility and efficiency of material transfer, thereby improving the production efficiency of the electric drive.

[0124] S608: When the shell sorting line online station triggers the material call demand, the production line or manual terminal triggers the shell semi-finished product outbound online instruction.

[0125] In S609, the robot system receives the outbound instruction, allocates the inventory outbound and off-shelf tasks, and dispatches forklifts and lurking robots to transfer the semi-finished shell products in the warehouse area to the shell sorting line online station.

[0126] S610, sorting is performed, and the shells are placed on the conveyor line tray after sorting. When the tray is full, the production line or the manual terminal triggers the full tray to pass through the air shower door and is transported to the end of the conveyor line. The production line triggers the post-sorting shell transfer instruction after sorting.

[0127] Among them, sorting can be done manually or by a robot arm to obtain the sorted shells. The conveyor line is set in the production line, and the air shower door is used to remove dust on the surface of the sorted shells.

[0128] See also Figure 7 , Figure 7 This is a top view of the conveyor line 701. A plurality of trays 702 are provided in the conveyor line 701 for placing the sorted shells. The conveyor line 701 transports the sorted shells to the air shower door 703, which removes dust on the surface of the sorted shells.

[0129] S611, the robot system receives the transfer instruction and dispatches the roller robot to the shell sorting line offline station for docking, takes full pallets, returns empty pallets, completes the picking and placing of goods, and continues to the shell stator assembly line for docking.

[0130] S612: After the semi-finished shell products are transported and sorted by the roller robot, they go to the on-line station of the shell stator subassembly line to apply for pick-up and delivery docking, deliver full pallets and take empty pallets. After the pick-up and delivery are completed, the roller robot goes to the off-line station of the shell sorting line to wait for docking instructions.

[0131] S613: When the semi-finished electric drive product is about to be produced at the off-line station of the shell stator subassembly line, the production line system triggers the instruction to transfer the semi-finished electric drive product to the line.

[0132] In S614, the robot system receives the transfer instruction and dispatches the roller robot to the shell stator subassembly line offline station to apply for pick-up and delivery docking, take full pallets, return empty pallets, and the pick-up and delivery are completed. The roller robot takes the elevator to the second floor electric drive main assembly line to dock, deliver full pallets, take empty pallets, and the pick-up and delivery are completed.

[0133] The roller robot transfers materials between the shell stator sub-assembly line and the electric drive main assembly line. During this process, the robot system needs to interact with the elevator system.

[0134] Among them, the shell processing line 514, the shell sorting line 522, the shell stator assembly line 524 and the finished product quality inspection line 532 are arranged on the first floor, and the electric drive main assembly line 527 is arranged on the second floor, that is, the electric drive main assembly line 527 is arranged on a different floor from other production lines in the production line. Based on this, the system is equipped with an elevator 526 and an elevator 531 between the first floor and the second floor. The elevator 526 and the elevator 531 can be the same elevator or two different elevators.

[0135] Steps S608 to S614 are the following steps:

[0136] Step 1: Transfer the semi-finished shell products stored in the third storage area 518 to the shell sorting line 522 .

[0137] Step 2: The shell sorting line 522 sorts the semi-finished shells to obtain sorted shells;

[0138] Step 3: transporting the sorted shells to the shell stator assembly line 524;

[0139] Step 4: The shell and stator subassembly line 524 sub-assembles the sorted shells to obtain semi-finished electric drive products;

[0140] Step 5: The roller robot 525 and the semi-finished electric drive product it transports are transported to the second floor by the elevator 526;

[0141] Step 6: The roller robot 525 transfers the semi-finished electric drive products in the elevator to the main electric drive assembly line 527.

[0142] Among them, the roller robot 525 and the roller robot 525 can be the same roller robot or two different roller robots.

[0143] The following will explain the above steps separately:

[0144] Step 1: Transfer the semi-finished shell products stored in the third storage area 518 to the shell sorting line 522 .

[0145] The loading part of the shell sorting line 522 is used to cooperate with the forking part of the second forklift robot 519 to transfer the shell semi-finished products forked by the second forklift robot 519 from the third storage area 518 to the shell sorting line 522 for sorting.

[0146] The second forklift robot 519 is arranged between the third storage area 518 and the on-line station of the shell sorting line 522, wherein the third storage area 518 is used to store the semi-finished shell products, which has the same function as the aforementioned second storage area 518. Therefore, the third storage area and the second storage area can be the same storage area or different storage areas. For the sake of convenience of description, they are both marked as storage area 518 here.

[0147] The unloading portion of the shell sorting line 522 is used to cooperate with the roller of the first roller robot 523 to transfer the shells sorted by the sorting line to the first roller robot 523. The first roller robot will be described in detail below and will not be repeated here.

[0148] In a possible embodiment, the second forklift robot 519 may directly transfer the semi-finished shell product to the shell sorting line 522 .

[0149] In order to improve the transfer efficiency and thus improve the production efficiency of the electric drive, in another possible embodiment, based on the same setting as the aforementioned first docking point 516, a second docking point 520 can be set between the third storage area 518 and the on-line station of the shell sorting line 522, and a fourth lurking robot 521 is set between the second docking point 520 and the on-line station of the shell sorting line 522. The second forklift robot 519 is set between the third storage area 518 and the second docking point 520, and the first shelf is also set in the second docking point 520.

[0150] Based on this, the loading part of the shell sorting line 522 is specifically used to cooperate with the first execution part of the fourth latent robot 521 to transfer the shell semi-finished products placed on the first shelf supported by the first execution part to the shell sorting line 522.

[0151] By selecting this embodiment, by adding a fourth lurking robot between the second docking point and the shell sorting line online station, and a third forklift robot between the third storage area and the second docking point, the robots can quickly transfer materials between the storage area and the sorting line, ensuring that the materials can be transferred to the sorting line in a timely and accurate manner, greatly improving the automation level and efficiency of material transfer, reducing manual intervention, improving the stability and reliability of the overall system, and thereby improving the efficiency of electric drive production.

[0152] Step 2: The shell sorting line 522 sorts the semi-finished shell products to obtain sorted shells.

[0153] In this step, the semi-finished shells can be screened according to user needs. For example, it can be pre-set to sort and screen out the semi-finished shells that do not meet the production standards, or it can be sorted and screened for semi-finished shells of different specifications, which is not specifically limited here.

[0154] Step 3: The sorted shells are transported to the shell stator assembly line 524.

[0155] In this step, the roller robot transfers the sorted shells to the shell stator assembly line 524. The roller robot can be provided with multiple rollers in a horizontal direction, and the multiple rollers are used to cooperate with each other to drive the materials placed on the rollers to move in the horizontal direction. Figure 8 , Figure 8 This is a structural diagram of the roller robot. The roller robot 801 is provided with multiple rollers 811. The upper left corner is a front view of the roller robot 801, the upper right corner is a left view of the roller robot 801, the lower left corner is a top view of the roller robot 801, and the lower right corner is a three-dimensional structural diagram of the roller robot 801.

[0156] The housing stator subassembly line 524 is provided between the housing sorting line 522 and the electric drive main assembly line 527. The housing stator subassembly line is used to sub-assemble the electric drive semi-finished products, and the electric drive main assembly line is used to assemble the electric drive semi-finished products to obtain the electric drive finished products.

[0157] The sorted shells are transferred to the loading section of the shell stator subassembly line 524 by a first roller robot 523 arranged between the downline station of the shell sorting line 522 and the upline station of the shell stator subassembly line 524 .

[0158] The loading portion of the shell stator subassembly line is used to cooperate with the first roller robot 523 to transfer the sorted shells carried by the first roller robot 523 to the shell stator subassembly line.

[0159] The unloading portion of the shell stator subassembly line is used to cooperate with the roller of the second roller robot 525 to transfer the output electric drive semi-finished product to the second roller robot 525.

[0160] This embodiment is selected to introduce a shell-stator subassembly line, which realizes efficient and accurate subassembly of the shell and stator after sorting, further improving the production efficiency and assembly quality of the electric drive products. The shell-stator subassembly line is cleverly arranged between the shell sorting line and the electric drive main assembly line, and can accurately transfer the sorted shell to the shell-stator subassembly line, avoiding the tediousness and errors of manual transfer, and transfers the packaged materials to the subsequent electric drive main assembly line through a roller robot, providing sufficient and orderly material support for the electric drive main assembly line. This series of designs not only greatly improves the degree of automation of the production line and reduces labor costs, but also ensures the quality of electric drive products by reducing potential errors in material transfer and production processes.

[0161] Step 4: The shell and stator subassembly line 524 sub-assembles the sorted shells to obtain semi-finished electric drive products.

[0162] The assembly assembly of the housing stator assembly line 524 assembles the sorted housings to obtain semi-finished electric drive products. Stators may be pre-placed on the housing stator assembly line 524. After the sorted housings are obtained, they are assembled to obtain semi-finished electric drive products.

[0163] Step 5: The elevator 526 transports the roller robot 525 and the semi-finished electric drive products it transports to the second floor.

[0164] After the unloading part of the shell stator subassembly line 524 cooperates with the roller of the second roller robot 525 to place the electric drive semi-finished products obtained by the shell stator subassembly line 524 on the roller of the second roller robot 525, the second roller robot 525 needs to transfer the electric drive semi-finished products to the electric drive main assembly line 527. However, since the electric drive main assembly line 527 is set on the second floor, the second roller robot 525 needs to transfer the electric drive semi-finished products to the electric drive main assembly line 527 by elevator.

[0165] Step 6: The roller robot 525 transfers the semi-finished electric drive products in the elevator to the main electric drive assembly line 527.

[0166] After reaching the second floor, the second roller robot 525 transfers the electric drive semi-finished product to the electric drive main assembly line 527.

[0167] When the production line also includes a shell stator sub-assembly line 524, the loading part of the electric drive main assembly line 527 is used to cooperate with the roller of the second roller robot 525 to transfer the electric drive semi-finished product on the second roller robot 525 to the electric drive main assembly line 527.

[0168] S615: The main assembly line of the electric drive is assembling. When the material is about to be taken off the line at the offline workstation, the production line system or manual terminal triggers the instruction for the electric drive finished product to be taken off the line and put into storage.

[0169] S616: The robot system receives the instruction, allocates a storage location in the incoming warehouse area, and dispatches the robot to transfer the electric drive assembly to an empty storage location in the target warehouse area for storage.

[0170] Steps S615 and S616 involve transferring the finished electric drive products to the fifth storage area 529 or the sixth storage area 529 for storage. Specifically, the third lurking robot 528 transfers the finished electric drive products to the fifth storage area 529 for storage. Both the fifth and sixth storage areas are used to store finished electric drive products. Therefore, the fifth and sixth storage areas can be the same storage area or different storage areas. For ease of description, both are labeled as storage area 529.

[0171] The fifth storage area 529 in this step is set on the same second floor as the electric drive main assembly line 527.

[0172] S617: When the online workstation on the quality inspection line triggers a material request, the production line or manual terminal triggers the instruction for the semi-finished shell to be shipped online.

[0173] In S618, the robot system receives the outbound instruction, allocates inventory and issues the task of outbound and off-shelf electric drive finished products, and dispatches the lurking robot to transport the electric drive finished products in the warehouse area to the online workstation of the finished product quality inspection line via the elevator.

[0174] In this step, the robot system needs to interact with the elevator system.

[0175] S619, the production line / manually determines whether the quality of the finished product is qualified. If so, execute step S620; if not, execute step S621.

[0176] The quality inspection line is used for inspection. After the inspection is completed, if the quality inspection is qualified, the production line system or manual terminal will trigger the qualified electric drive assembly to be taken off the line and put into storage; if the quality inspection is unqualified, the production line system or manual terminal will trigger the unqualified electric drive assembly to be transferred to the defective product processing area.

[0177] S620: The robot system receives the instruction, allocates storage space in the incoming warehouse area, and dispatches the forklift robot to transport the qualified electric drive finished products to the target warehouse area for stacking and storage.

[0178] Steps S617 to S620 are to transfer the finished electric drive products to the finished product quality inspection line 532 for quality inspection, and transfer the finished electric drive products that pass the quality inspection to the seventh storage area 534 .

[0179] The loading part of the finished product quality inspection line 532 is used to cooperate with the first execution part of the sixth latent robot 530 to transfer the electric drive finished products placed on the first shelf supported by the first execution part to the finished product quality inspection line 532.

[0180] The unloading part of the finished product quality inspection line 532 is used to cooperate with the second execution part of the third forklift robot 533, so that the second execution part forks the electric drive that has passed the quality inspection output by the finished product quality inspection line and transfers the electric drive that has passed the quality inspection to the seventh storage area 534 for storage.

[0181] Since the finished product quality inspection line 532 is set on the first floor, after the sixth latent robot 530 transfers the electric-driven finished product from the fifth storage area 529, it needs to transfer the electric-driven finished product to the first floor through the elevator 531, and then transfer it to the finished product quality inspection line 532.

[0182] This embodiment efficiently integrates the finished product quality inspection line with the fifth lurking robot and the third forklift robot, ensuring that assembled electric drive products can be quickly and accurately transferred from the storage area to the quality inspection assembly, avoiding the tediousness and errors of manual transfer. It also enables qualified electric drive products to be quickly and stably forked and transferred to the storage area, preparing for subsequent outbound delivery and shipment. This series of designs not only significantly improves the automation level of material transfer and electric drive production, reduces labor costs, and improves the efficiency of material transfer, but also ensures the high quality of electric drive products through a strict quality inspection process.

[0183] In S621, the robot system receives the transfer instruction and dispatches the forklift robot to transfer the unqualified electric drive finished product to the defective product processing area for manual processing.

[0184] In a possible embodiment, it may also include a fourth storage area 5274 for storing assembly parts, which is used to transport raw materials or parts required for assembling electric drive finished products to the electric drive main assembly line 527. Based on this, the loading part of the electric drive main assembly line 527 is also used to cooperate with the third execution part of the first material box robot 5273 to transfer the materials in the material box transported by the first material box robot 5273 to the electric drive main assembly line 527.

[0185] The first material box robot 5273 is arranged between the on-line station of the electric drive main assembly line 527 and the fourth storage area 5274.

[0186] This embodiment, through meticulously divided storage areas and equipped with appropriate shelving and robots, enables efficient circulation of semi-finished housings, assembly parts, and finished electric drive products around the main electric drive assembly line. Forklift robots and bin robots precisely deliver the required materials to the assembly line, while a third lurking robot quickly transports finished products from the assembly line to the storage area. The entire process is highly automated, significantly improving the efficiency and accuracy of material transfer, and thus, electric drive production.

[0187] In order to improve the transfer efficiency, a third docking point 5272 can be set between the online workstation of the electric drive main assembly line 527 and the fourth storage area 5274, a fifth latent robot 5271 can be set between the third offline workstation and the third docking point 5282, and the first material box robot 5273 is set between the third docking point 5272 and the fourth storage area 5274. The third docking point 5272 is also provided with a first shelf.

[0188] The fourth storage area and the ninth storage area are both used to store assembly parts, so the fourth storage area and the ninth storage area can be the same storage area or different storage areas. For the convenience of description, they are both marked as storage area 5274 here.

[0189] The loading part of the electric drive main assembly line 527 is specifically used to cooperate with the first execution part of the fifth latent robot 5271 to transfer the materials placed on the first shelf supported by the first execution part to the electric drive main assembly line 527.

[0190] The selection of this embodiment not only reduces labor costs and potential risks in the material transfer process, but also improves the automation and efficiency of material transfer and electric drive production, significantly improving the efficiency of material transfer and electric drive production.

[0191] The materials in the fourth storage area 5274 can be transferred from the receiving platform 510 by any lurking robot 5275 and the second material box robot 5276.

[0192] The above embodiments are written for a production line that includes a shell processing line, a shell sorting line, a shell stator assembly line, an electric drive main assembly line, and a finished product quality inspection line. In other embodiments, the production line may also include only one or more of them, which will not be repeated here.

[0193] For ease of understanding, the above Figure 5 Can be simplified to Figure 9 , Figure 9 The storage area A is the aforementioned first storage area and the eighth storage area, the storage area B is the aforementioned second storage area and the third storage area, the storage area C is the aforementioned fifth storage area and the sixth storage area, the storage area D is the aforementioned seventh storage area, and the storage area E is the aforementioned fourth storage area and the ninth storage area. Figure 9 The steps performed by the receiving platform, production line, storage areas, robots, and elevators are the same as those described above and will not be repeated here.

[0194] It is understandable that the aforementioned Figures 1-9 The structure of the production line, shelf and robot shown is only a possible schematic diagram provided by the embodiment of the present invention. In other embodiments, the structure of the production line, shelf and robot can also be the same as the above. Figures 1-9 Different, no specific limitation is made here.

[0195] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
