[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] In the field of vehicle manufacturing, the manufacturing and forming of automobile covering parts is involved. Automobile covering parts can be parts that constitute the surface of the space such as the driver's cab and passenger compartment in the whole vehicle, such as door outer panels, roof covers, trunk lid lining panels, instrument panels and other parts. The stamping forming of automobile covering parts is a common process in the whole vehicle manufacturing process. Specifically, the sheet is pressed on the press by the mold to deform it, so as to obtain parts of the required shape and size.

[0048] In actual production, the sheet materials used for stamping are generally placed in corresponding mold cavity positions, and different mold cavity positions correspond to different types of molds, so that different sheet materials can be stamped to obtain different types of automobile covering parts.

[0049] Currently, the sheets for stamping are stacked in the corresponding area and unstackered during actual production to place the sheets in the corresponding cavity positions.

[0050] However, since the stacking position of the sheets is random each time they are stacked, and thus distributed in different positions in the corresponding area, the position of destacking the sheets is different each time, making it difficult to destacker based on the position of the sheets. In the event that destacking is impossible, the position of the sheets must be manually corrected, resulting in low production efficiency, high labor costs, and the risk of production accidents.

[0051] At the same time, due to the different stacking positions of the sheets, the positions of the sheets in the production line are also different after each destacking. As a result, the position of a certain sheet may be different from the position of the mold cavity, resulting in the inability to stamp the sheet. In the event that stamping is impossible, the position of the sheet must be manually corrected, resulting in low production efficiency, high labor costs, and the risk of production accidents.

[0052] Based on this, the present application provides a method for determining a production standard, by obtaining the mold cavity position corresponding to at least one sheet material type, different sheet material types correspond to different mold cavity positions, and obtaining the stroke range of the automatic feeding system, and then determining the production parameters corresponding to any sheet material type based on the stroke range and the mold cavity position corresponding to any sheet material type, and the production parameters corresponding to any sheet material type can control the automatic feeding system to move the sheet material of the sheet material type to the corresponding mold cavity position during the production process, and then can control the corresponding sheet material to move to the corresponding mold cavity position for production based on the production parameters, and different sheet material types correspond to different production parameters, so that sheets of each sheet material type can reach the exact mold cavity position, reducing the situation where the sheet material cannot reach the exact mold cavity position and cannot be stamped, thereby reducing the situation where the position of the sheet material needs to be adjusted manually, improving production efficiency, reducing labor costs and reducing the risk of production accidents.

[0053] See also Figure 1 , Figure 1 A flowchart of a method for determining a production standard provided by an embodiment of the present application is shown. The method can be performed by an automatic feeding system, or by a terminal device other than the automatic feeding system (such as a computer, server, mobile phone, computer, etc.), and specifically can include the following steps:

[0054] Step 101, obtaining a mold cavity position corresponding to at least one sheet material type.

[0055] Among them, the sheet type can be the type of sheet, specifically corresponding to the type of automobile covering parts, that is, different types of automobile covering parts can be obtained by stamping different types of sheets, and the cavity position can be the position where the sheet is stamped, specifically, it can be the position where different types of molds are stamped in the production line. Different sheet types can correspond to different molds, that is, different sheet types can correspond to different cavity positions.

[0056] In practical applications, at least one sheet material type can be determined, such as the door outer panel type, the top cover type, and the trunk lid type, and each sheet material type will have at least one specification, each specification corresponds to a different car model, and then all sheet material types of all specifications can be determined to obtain at least one sheet material type.

[0057] In actual production, a production line can deploy multiple molds to stamp various types of sheet materials, so that a variety of automotive covers can be produced. Each mold is deployed at a different position in the production line, and the position of the mold cavity for stamping is also different. For each type of sheet material, the mold used to stamp the sheet material type in the production line can be determined, and the position of the mold for stamping can be determined, that is, the mold cavity position corresponding to the sheet material type, and then the mold cavity position corresponding to each sheet material type can be obtained.

[0058] Step 102, obtaining the travel range of the automatic feeding system.

[0059] Among them, the automatic feeding system can be a system that moves the sheet to the corresponding mold cavity position, and the stroke range can be the stroke range of the automatic feeding system, including the rotation angle range, the robot arm movement range, the baffle movement range, etc.

[0060] In actual production, it is also possible to obtain the parameters of each unit in the automatic feeding system, such as the length of the robot arm, the rotation limit angle, the screw stroke and other parameters, and determine the stroke range of the automatic feeding system based on the obtained parameters.

[0061] Step 103, determining the production parameters corresponding to any sheet material type according to the stroke range and the mold cavity position corresponding to any sheet material type.

[0062] Among them, the production parameters corresponding to any sheet material type can be used to control the automatic feeding system to move the sheet material of the sheet material type to the corresponding mold cavity position during the production process. The production parameters may include parameters such as the rotation angle of the automatic feeding system and the moving stroke of the robotic arm.

[0063] After obtaining the travel range and the mold cavity position corresponding to any sheet material type, for each sheet material type, the stacking position of the sheet material type can be determined, and then based on the stacking position of the sheet material type, the mold cavity position corresponding to the sheet material type and the travel range of the automatic feeding system, a route and at least one step can be planned to move the sheet of the sheet material type from the stacking position to the corresponding mold cavity position, and the production parameters such as the rotation angle required by the automatic feeding system in each step, the moving stroke of the robot arm, etc., can be determined, and then the production parameters corresponding to each sheet material type can be obtained.

[0064] In an embodiment of the present application, the method provided in the embodiment of the present application may also include the following steps:

[0065] Based on the production parameters corresponding to any sheet material type, the automatic feeding system is controlled to move the sheet material of that type to the corresponding mold cavity position for production.

[0066] As an example, if the executor of the present application is a terminal device, the terminal device can control the automatic feeding system according to the production parameters corresponding to any sheet material type to move the sheet material of the sheet material type to the corresponding mold cavity position for production.

[0067] For example, the terminal device can send production parameters corresponding to any sheet material type to the automatic feeding system to instruct the automatic feeding system to move the sheet material of the sheet material type to the corresponding mold cavity position for production.

[0068] As another example, if the execution subject of the present application is an automatic feeding system, the automatic feeding system can, after determining the production parameters corresponding to any sheet type, move the sheet of the sheet type to the corresponding mold cavity position for production based on the production parameters corresponding to any sheet type. For example, after determining the production parameters corresponding to any sheet type, the automatic feeding system can, in response to the received production instruction, move the sheet of the sheet type to the corresponding mold cavity position for production based on the production parameters corresponding to any sheet type.

[0069] After obtaining the production parameters corresponding to each sheet material type, in actual production, the sheet material that currently needs to be moved and the sheet material type of the sheet material can be determined, and then the production parameters corresponding to the sheet material type can be determined. The automatic feeding system can set the current production parameters to the production parameters corresponding to the sheet material type, so that the sheet material can be controlled to move to the corresponding mold cavity position based on the production parameters corresponding to the sheet material type for stamping production.

[0070] In an embodiment of the present application, by obtaining the mold cavity position corresponding to at least one sheet material type, different sheet material types correspond to different mold cavity positions, and obtaining the stroke range of the automatic feeding system, and then determining the production parameters corresponding to any sheet material type based on the stroke range and the mold cavity position corresponding to any sheet material type, and the production parameters corresponding to any sheet material type can control the automatic feeding system to move the sheet material of the sheet material type to the corresponding mold cavity position during the production process, and then can control the corresponding sheet material to move to the corresponding mold cavity position for production based on the production parameters, and different sheet material types correspond to different production parameters, so that sheets of each sheet material type can reach the exact mold cavity position, reducing the situation where the sheet material cannot reach the exact mold cavity position and cannot be stamped, thereby reducing the situation where the position of the sheet material needs to be adjusted manually, improving production efficiency, reducing labor costs and reducing the risk of production accidents.

[0071] See also Figure 2 , Figure 2 A flowchart showing another method for determining a production standard provided by an embodiment of the present application is shown, which may specifically include the following steps:

[0072] Step 201, obtaining a mold cavity position corresponding to at least one type of sheet material.

[0073] Step 202, obtaining the travel range of the automatic feeding system.

[0074] For the related descriptions of step 201 to step 202, please refer to step 101 to step 102, and they will not be repeated here.

[0075] Step 203, determining a first intermediate posture corresponding to any sheet material type and the tray, and a second intermediate posture corresponding to any sheet material type and the conveyor belt according to the stroke range and the mold cavity position corresponding to at least one sheet material type.

[0076] Among them, the pallet can be a device for carrying the sheet material, the conveyor belt can be a device for conveying the sheet material to the mold cavity position, the first intermediate posture can be the posture of the sheet material stacked in the pallet, and the second intermediate posture can be the posture of the sheet material placed in the conveyor belt. The posture includes position and postures such as horizontal angle and vertical angle.

[0077] Specifically, the second intermediate posture can be a position in the conveyor belt at which the sheet material placed on the conveyor belt can be moved to the corresponding mold cavity position based on the travel range of the automatic feeding system, and the first intermediate posture can be a position in the tray at which the sheet material placed on the tray can be moved to the second intermediate posture based on the travel range of the automatic feeding system.

[0078] In actual production, the sheets can be stacked in the corresponding pallets through the automatic feeding system, and the sheets can be destackered from the pallets and placed on the conveyor belt. Then, the first intermediate position of each sheet type in the pallet and the second intermediate position in the conveyor belt need to be determined according to the travel range of the automatic feeding system and the mold cavity position corresponding to the sheet type.

[0079] In a specific implementation, a two-dimensional drawing of each unit in the automatic feeding system can be obtained, and a two-dimensional design software, a three-dimensional design software or a simulation software can be used to simulate the operation of each unit of the automatic feeding system in actual production according to the obtained two-dimensional drawing, and determine the stroke limit of each unit, that is, determine the stroke range of each unit, and then, according to the mold cavity position corresponding to each sheet material type and the stroke limit of each unit, determine the intermediate position of the sheet material type in each device, such as the first intermediate position in the tray and the second intermediate position in the conveyor belt.

[0080] Step 204: Determine production parameters corresponding to any sheet material type according to the first intermediate posture and the second intermediate posture.

[0081] For each sheet material type, after obtaining the first intermediate position and the second intermediate position of the sheet material type, the production parameters for controlling the automatic feeding system to move the sheet material of the sheet material type from the second intermediate position to the mold cavity position can be determined according to the stroke range of the automatic feeding system, the mold cavity position of the sheet material type and the second intermediate position. The production parameters for the automatic feeding system to move the sheet material of the sheet material type from the first intermediate position to the second intermediate position can also be determined according to the stroke range of the automatic feeding system, the second intermediate position of the sheet material type and the first intermediate position. The production parameters for controlling the automatic feeding system to stack the sheets of the sheet material type in the first intermediate position can also be determined according to the stroke range of the automatic feeding system and the first intermediate position.

[0082] In one embodiment of the present application, the automatic feeding system may include a stacking unit, a destacking unit and a centering unit. The stacking unit may be used to stack the sheets in a pallet, the destacking unit may be used to destacking the sheets stacked in the pallet and place them in a conveyor belt, and the centering unit may be used to adjust the posture of the sheets placed in the conveyor belt. The travel range of the automatic feeding system includes the travel range of the stacking unit, the travel range of the destacking unit, and the travel range of the centering unit. The production parameters may include one or more of the following: a first parameter, a second parameter, and a third parameter. The first parameter may indicate that the stacking unit in the automatic feeding system stacks the sheets corresponding to any sheet type to the first position in the pallet, that is, the first parameter may correspond to the stacking unit, and the first position is a position corresponding to the first intermediate posture. The second parameter may be used to indicate that the destacking unit in the automatic feeding system moves the sheets corresponding to any sheet type from the first position to the second position in the conveyor belt, that is, the second parameter corresponds to the destacking unit, and the second position is a position corresponding to the second intermediate posture. The third parameter can be used to instruct the centering unit in the automatic feeding system to move the sheet corresponding to any sheet type from the second position to the corresponding mold cavity position, that is, the third parameter can correspond to the centering unit.

[0083] In a specific implementation, for each sheet material type, the mold cavity position corresponding to the sheet material type and the stroke range of the centering unit can be determined, the second intermediate position of the sheet material type when placed in the conveyor belt can be determined, and based on the second intermediate position, the stroke range of the destacking unit and the stroke range of the stacking unit, the first intermediate position of the sheet material type when placed in the pallet can be determined.

[0084] Specifically, the second intermediate posture corresponding to any type of sheet material in the conveyor belt can be determined by the mold cavity position corresponding to any type of sheet material and the travel range of the destacking unit.

[0085] In practical applications, for each type of sheet material, the area in which the centering unit can be positioned in the conveyor belt can be determined based on the mold cavity position corresponding to the sheet material type and the travel range of the centering unit, that is, the centering unit can move the sheet material placed in the area to the corresponding mold cavity position, and then, based on the travel range of the destacking unit, at least one posture that the destacking unit can reach can be determined from the area in which the centering unit can be positioned in the conveyor belt, and any one posture among all the postures that can be reached can be determined as the second intermediate posture.

[0086] In an embodiment of the present application, the method provided in the embodiment of the present application may also include the following steps:

[0087] According to the travel range of the depalletizing unit and the second intermediate posture corresponding to any type of sheet material, the target depalletizing range of the depalletizing unit is determined.

[0088] The target destacking range may be that the destacking unit performs a destacking operation and moves sheets of any sheet type to a corresponding second intermediate position, and the destacking operation may be an operation of separating sheets stacked in a pallet.

[0089] For each sheet material type, after obtaining the second intermediate posture corresponding to the sheet material type, the range within which the destacking unit can perform the destacking operation and move the sheet of this sheet material type to the second intermediate posture can be determined based on the second intermediate posture corresponding to the sheet material type and the travel range of the destacking unit, which is the target destacking range.

[0090] Since the depalletizing unit generally performs the depalletizing operation in a pallet, it can be determined that the range in which the depalletizing unit can perform the depalletizing operation is in the corresponding area of ​​the pallet, that is, the target depalletizing range is in a certain area of ​​the pallet.

[0091] Specifically, the first intermediate posture corresponding to any sheet material type and the pallet can be determined according to the size of the target pallet type, the sheet material size and the travel range of the depalletizing unit. The target pallet type can be the type of pallet corresponding to any sheet material type.

[0092] In practical applications, for each sheet material type, the target pallet type corresponding to the sheet material type can be determined.

[0093] It should be understood that, since sheets of different sheet types have different sizes and shapes, the pallets used to carry the sheets also have different sizes and shapes. Based on this, for each sheet type, a pallet used to carry the sheets corresponding to the sheet type can be predefined based on the size and shape of the sheets of the sheet type.

[0094] For example, for a rectangular sheet with a length of 1880 mm and a width of 450 mm, the pallet carrying the sheet can be defined as a rectangular pallet with a length of 2000 mm and a width of 480 mm, or the pallet carrying the sheet can be defined as a standard pallet with a minimum side length of 2000, and the standard pallet is a square pallet.

[0095] After pre-defining the pallet corresponding to each sheet material type, the sheet material type of the sheet material to be produced can be determined in actual production, and the target pallet type corresponding to the sheet material type can be selected from all defined pallets, and then the pallet of the target pallet type can be used to carry the sheets of this sheet material type, that is, the sheets of this sheet material type can be stacked in the pallet of the target pallet type.

[0096] For each sheet type, after determining the target pallet type corresponding to the sheet type, the size of the target pallet type and the size of the sheet corresponding to the sheet type can be determined. Then, based on the size of the target pallet type corresponding to the sheet type and the size of the sheet corresponding to the sheet type, the position of the sheet in the pallet of the target pallet type can be determined from the target depalleting range, which is the first intermediate position.

[0097] In an embodiment of the present application, step 204 may include steps 2041 to 2043:

[0098] Step 2041: Determine a first parameter of the stacking unit for any type of sheet material according to the first intermediate posture.

[0099] For each sheet type, after obtaining the first intermediate posture corresponding to the sheet type, the first parameter of the stacking unit can be determined according to the first intermediate posture and the travel range of the stacking unit, that is, the parameter used to control the stacking unit to stack the sheets in the first intermediate posture.

[0100] Specifically, the first parameter may include parameters of some or all steps involved in the stacking unit stacking the sheets in the first intermediate position, and may also include the execution order of each step and parameters such as the moving distance and rotation angle of the stacking unit in each step.

[0101] Step 2042: Determine the second parameter of the depalletizing unit for any type of sheet material according to the first intermediate posture, the second intermediate posture and the travel range of the depalletizing unit.

[0102] For each sheet type, after obtaining the first intermediate posture and the second intermediate posture corresponding to the sheet type, the second parameter of the destacking unit can be determined according to the first intermediate posture, the second intermediate posture and the travel range of the destacking unit, that is, the parameters used to control the destacking unit to move the sheet from the first intermediate posture to the second intermediate posture can be determined.

[0103] Specifically, the second parameter may include parameters of some or all steps involved in the process of the destacking unit moving the sheet from the first intermediate position to the second intermediate position, and may also include the execution order of each step and parameters such as the moving distance and rotation angle of the destacking unit in each step.

[0104] In one embodiment of the present application, the destacking unit may include a side stop device and a spreader device. The travel range of the destacking unit may include the travel range of the side stop device and the travel range of the spreader device. The side stop device can be used to separate sheets, and the spreader device can be used to separate at least two sheets. The second parameter includes the production parameters of the side stop device and the production parameters of the spreader device.

[0105] In a specific implementation, for each sheet type, after obtaining the first intermediate posture and the second intermediate posture corresponding to the sheet type, the production parameters of the side stop device and the production parameters of the spreader device can be determined based on the first intermediate posture, the second intermediate posture, the stroke range of the side stop device, and the stroke range of the spreader device.

[0106] In an embodiment of the present application, the method provided in the embodiment of the present application may also include the following steps:

[0107] A target separator type corresponding to the sheet material type is determined from at least two preset separator types, wherein the separator device of the target separator type is used to separate at least two sheets of material.

[0108] As an example, the method provided in the embodiment of the present application may further include: controlling a separator device of the target separator type to separate at least two sheets.

[0109] Among them, the separator type can be the type of separator device, including a pawl type, a suction cup type, and a magnetic type. Specifically, different sheet types correspond to different separator types, that is, different sheets require different types of separator devices for grasping and separation.

[0110] For each sheet material type, the target separator type corresponding to the sheet material type can be determined from at least two preset separator types, and the separator type used for destacking the sheet material type in the destacking unit can be determined as the target separator type, and then the separator device of the target separator type can be used to perform the operation of separating at least two sheets, that is, the destacking operation is performed using the separator device of the target separator type.

[0111] In actual applications, the types of separators corresponding to different sheet material types can be pre-defined. For example, when the sheet material type is aluminum sheet material, the type of separator used can be a ratchet type, and when the sheet material type is steel sheet material, the type of separator used can be a magnetic type, so that in actual production, the separator device corresponding to the sheet material type can be used to perform destacking operations.

[0112] In one embodiment of the present application, the destacking unit may further include an end-of-material detection unit and a double-material detection unit. The end-of-material detection unit may be used to determine whether there is only one sheet left in the sheet stack. If so, the production operation is stopped and an alarm is issued to prompt the staff to replenish the sheet. If not, the production operation is continued. The double-material detection unit may be used to detect whether the destacking unit grabs at least two sheets at the same time when performing the destacking operation. If so, the production operation is stopped and an alarm is issued to prompt the staff to perform the corresponding operation. If not, the production operation is continued.

[0113] Step 2043: Determine the third parameter of the centering unit for any type of sheet material according to the second intermediate posture and the travel range of the centering unit.

[0114] For each sheet type, after obtaining the second intermediate posture corresponding to the sheet type, the third parameter of the centering unit can be determined according to the second intermediate posture corresponding to the sheet type, the mold cavity position corresponding to the sheet type and the stroke range of the centering unit, that is, the parameter used to control the centering unit to move the sheet from the second intermediate posture to the mold cavity position.

[0115] Specifically, the third parameter may include parameters of some or all steps involved in the process of the centering unit moving the sheet from the second intermediate position to the mold cavity position, and may also include the execution order of each step and parameters such as the movement distance and rotation angle of the centering unit in each step.

[0116] In one embodiment of the present application, for each sheet type, in order to move the sheet of that sheet type from the second intermediate position corresponding to the sheet type to the corresponding mold cavity position, it is also necessary to determine the production parameters of the conveyor belt according to the mold cavity position and the second intermediate position, including the conveying speed, conveying time and other parameters of the conveyor belt.

[0117] In an embodiment of the present application, by obtaining the mold cavity position corresponding to at least one type of sheet material, different sheet material types correspond to different mold cavity positions, and obtaining the travel range of the automatic feeding system, and then according to the travel range and the mold cavity position corresponding to at least one type of sheet material, the first intermediate posture corresponding to any sheet material type and the pallet, and the second intermediate posture corresponding to any sheet material type and the conveyor belt are determined, and according to the first intermediate posture and the second intermediate posture, the production parameters corresponding to any sheet material type are determined, and then the corresponding sheet material can be controlled to move to the corresponding mold cavity position for production based on the production parameters, and different sheet material types correspond to different production parameters, so that sheets of each sheet material type can reach the accurate mold cavity position, reducing the situation where the sheet material cannot reach the accurate mold cavity position and cannot be stamped, thereby reducing the situation where the position of the sheet material needs to be adjusted manually, improving production efficiency, reducing labor costs and reducing the risk of production accidents.

Optionally, the automatic feeding system also includes a conveyor belt and a tray, wherein area 1 in the tray can be a first intermediate posture, area 2 in the conveyor belt can be a second intermediate posture, and area 3 in the conveyor belt can be a mold cavity position.

[0119] In actual production, for each sheet type, the stacking unit 31 can collect sheets of that sheet type and stack the sheets in a first intermediate position 1 corresponding to the sheet type in the pallet based on a first parameter, and the destacking unit 32 can move the sheet from the first intermediate position 1 to the second intermediate position 2 based on a second parameter, and then the centering unit can adjust the placement angle of the sheet in the conveyor belt based on a third parameter, so that the placement angle of the sheet is adjusted from the second intermediate position 2 to a placement angle matching the mold cavity position, so that the conveyor belt can move the sheet from the adjusted second intermediate position to the mold cavity position corresponding to the sheet type based on the production parameters corresponding to the sheet type, so as to perform stamping production in the mold cavity position.
