[0002] Small sheet metal products are widely used in various industries such as automotive parts. They usually need to be precisely designed and processed to ensure dimensional accuracy and surface quality. The automated production process of sheet metal products includes coil loading, feeding, flattening, refueling, punch blanking, forming, automatic transfer, automatic positioning and blanking. For small sheet metal products, they need to go through the punch blanking and re-forming processes. At present, these processes mainly rely on manual loading and unloading, and cooperate with corresponding molds to complete production.

[0003] In the traditional manual feeding production process, the incoming material is a coil, which is first flattened by a flattening machine and then fed into the punching die. After the blanking is completed, the sheets are separated into a material box and arranged in a scattered state. Then, the sheet is manually placed into the forming die for stamping and finally the product is taken out manually. The above production method requires the collaboration of multiple people, which not only consumes a lot of manpower, but also has a high equipment occupancy rate.

[0030] See also Figure 1 and Figure 4The present invention provides a small sheet metal production line, including a transfer area, a processing area and a forming area; the transfer area is provided with a temporary storage 1 for storing sheet metal coils 100, a loading vehicle 2 for moving the sheet metal coils 100 and a feeding tray 3 for positioning the sheet metal coils 100; the processing area is provided with a flattening mechanism 4 and an oiling mechanism 5 for the sheet metal coils 100; the forming area is provided with a punching machine 6 and a transfer and unloading robot 7; wherein the sheet metal coils 100 in the temporary storage 1 are transferred to the feeding tray 3 for positioning via the loading vehicle 2, and the sheet metal coils 100 are fed into the punching machine 6 via the feeding tray 3 via the flattening mechanism 4 and the oiling mechanism 5, and are transferred by the transfer and unloading robot 7 after blanking and forming.

[0031] Specifically, in an embodiment of the present invention, for an assembly line of small sheet metal products, it generally includes the transportation and processing of sheet metal raw materials, and is divided into a transfer area for raw materials, i.e., sheet metal coils 100, a pre-processing area for processing, and a sheet metal forming area for raw materials in the production line. The entire production line can coordinate the operation of each part of the equipment through integrated automation control, and can control the operation of each link through PLC (programmable logic controller) or DCS (distributed control system), such as the scheduling of the loading vehicle 2 of the sheet metal coil 100. Automatic positioning, flattening and oiling of the sheet metal coil 100. Synchronous operation of the punch 6 and the transfer and unloading robot 7. Fault alarm and data monitoring during the production process, etc.

[0032] More specifically, in the transfer area, its main functions include a temporary storage warehouse 1, a loading car 2 and a feeding tray 3. The temporary storage warehouse 1 is used to store sheet metal coils 100 and provide sufficient storage space to store sheet metal coils 100 of various models and specifications. The temporary storage warehouse 1 can be a three-dimensional shelf structure to maximize space utilization, and the stacking of sheet metal coils 100 can be moved by a forklift or a loading car 2. The loading car 2 can automatically transfer the sheet metal coils 100 according to the needs of the production line, and carry and transfer the sheet metal coils 100 through the mechanical structure assembled thereon, thereby reducing manual operations and improving work efficiency. The loading car 2 is also equipped with a positioning module that can be docked with the feeding tray 3. The feeding tray 3 is to position the coils and transport them to the flattening mechanism 4 and the oiling mechanism 5 of the processing area. The feeding tray 3 can be a device with a clamp or a vacuum adsorption function to ensure that the sheet metal coils 100 remain stable during transportation to the processing area, so that the sheet metal coils 100 can accurately enter the subsequent processing equipment.

[0033] In the processing area, its main functions include flattening and oiling. The flattening mechanism 4 is used to flatten the sheet metal coil 100 into a sheet metal sheet to eliminate the curling and corrugation in the sheet metal coil 100, making it flat and convenient for subsequent processing. The flattening mechanism 4 is generally composed of a plurality of flattening rollers, which gradually pressurize the coil to ensure the flatness of the coil. The number, spacing and pressure of the flattening rollers should be adjusted according to the sheet metal coil 100 of different materials and thicknesses. The oiling mechanism 5 is used to lubricate the surface of the flattened sheet metal sheet with oil to reduce friction in the subsequent processing process, prevent rust, and improve surface smoothness.

[0034] In the forming area, the main functional equipment includes a punching machine 6 and a transfer and unloading robot 7. The punching machine 6 punches the sheet metal sheet through the mold to complete the shearing, punching, forming and other processes. The transfer and unloading robot 7 is used to move the sheet metal parts formed by the punching machine 6 and automatically transfer them to the next workstation or collection area through the robot. The transfer and unloading robot 7 is equipped with a suction cup, a clamp or a mechanical claw, which can flexibly grab and carry the formed sheet metal parts. The robot can move quickly around the punching machine 6 to reduce manual intervention.

[0035] In this way, the traditional sheet metal production process is upgraded through production line design, and the precise layout of the transfer area, processing area and forming area is combined to optimize the collaboration between the various processes and improve the overall production efficiency. Automated equipment such as the loading car 2, feeding tray 3, flattening mechanism 4, oiling mechanism 5, punching machine 6 and transfer and unloading manipulator 7 form an efficient production system, which can improve production efficiency while reducing labor costs and ensuring the stability of sheet metal product quality.

[0036] See also Figure 2 In one embodiment, the loading cart 2 includes a four-way driving mechanism 21, a lifting and rotating mechanism 22 and a supporting mechanism 23. The four-way driving mechanism 21 is installed at the bottom of the loading cart 2, the lifting and rotating mechanism 22 is installed in the loading cart 2, and the supporting mechanism 23 is installed on the top of the lifting and rotating mechanism 22. The supporting mechanism 23 is used to place the sheet metal coil 100.

[0037] Specifically, in an embodiment of the present invention, the four-way drive mechanism 21 is used to realize the free movement of the loading vehicle 2 in any direction (front, back, left, right) on the plane, so as to realize accurate positioning and flexible scheduling. The four-way drive mechanism 21 can select the four-way vehicle as the chassis of the loading vehicle 2 to be used directly. The lifting and rotating mechanism 22 is installed in the middle of the loading vehicle 2, and is used to support and adjust the height and angle of the supporting mechanism 23, so that the supporting mechanism 23 can be accurately positioned and rotated as needed, and adapt to the movement process in different production requirements. The lifting function of the lifting and rotating mechanism 22 can be controlled by adopting an electric lifting method such as an electric lead screw to control itself and carry the supporting mechanism 23 to rise and fall synchronously, so as to adjust the height of the sheet metal coil 100 carried, and ensure docking with the feeding tray 3. Similarly, its rotation function can also be driven by a servo motor to facilitate the adjustment of the angle of the sheet metal coil 100 carried to align with the required position such as the shelf and feeding tray 3 of the temporary storage warehouse 1. The supporting mechanism 23 is the top portion of the loading vehicle 2 and is used to carry and place the sheet metal coil 100 .

[0038] Thus, by combining the four-way driving mechanism 21, the lifting and rotating mechanism 22 and the supporting mechanism 23, the loading vehicle 2 can flexibly and efficiently complete the transportation and positioning process of the sheet metal coil 100. The cooperation of each functional module makes the whole process more automated, and the loading vehicle 2 can realize automatic switching of sheet metal coils, reduce manual intervention, and improve the overall work efficiency and safety of the production line.

[0039] See also Figure 2 In one embodiment, the four-way driving mechanism 21 includes a first directional driving wheel 211 and a second directional driving wheel 212. The moving directions of the first directional driving wheel 211 and the second directional driving wheel 212 on the horizontal plane are perpendicular to each other. The four-way driving mechanism 21 selects the first directional driving wheel 211 or the second directional driving wheel 212 to touch the ground and move by adjusting the height of the first directional driving wheel 211 and the second directional driving wheel 212 in the vertical direction.

[0040] Specifically, in an embodiment of the present invention, the corresponding functions of the four-way drive mechanism 21 can be directly replaced by selecting a four-way vehicle, that is, in the four-way drive mechanism 21, each wheel can be equipped with an independent electric drive system, and the rotation speed of each wheel can be adjusted as needed to ensure that the vehicle can move freely. When it is necessary to move along the first direction on the horizontal plane, the first direction drive wheel 211 is lowered to the ground, contacted with the ground and provided with a motion driving force. The second direction drive wheel 212 is raised to avoid contact with the ground. When it is necessary to move along the second direction on the horizontal plane, the second direction drive wheel 212 is lowered to the ground on the horizontal plane, so that it touches the ground and provides a corresponding motion driving force. At this time, the first direction drive wheel 211 is raised to avoid contact with the ground. By changing the height of the drive wheel in the vertical direction, it is possible to select which pair of wheels to contact the ground, thereby realizing the desired motion direction selection.

[0041] See also Figure 3 In one embodiment, the lifting and rotating mechanism 22 includes a lifting component 221, a rotating component 222 and a tray 223. The lifting component 221 and the rotating component 222 drive the tray 223 to move in the vertical direction and rotate in the horizontal direction respectively. The tray 223 is equipped with a supporting mechanism 23. The shape of the area on the supporting mechanism 23 where the sheet metal coil 100 is placed matches the contour of the sheet metal coil 100 in contact.

[0042] Specifically, the function of the lifting and rotating mechanism 22 is to enable the tray 223 to be lifted in the vertical direction and rotated in the horizontal direction through two independent motion modes of lifting and rotating, thereby realizing multi-directional operation and movement of the loaded items. The lifting component 221 can be composed of three vertically installed ball screws and screw nuts, and connected through a synchronous belt mechanism or a gear mechanism, and driven by a servo motor to achieve the synchronous lifting function of lifting large loads; the rotating component 222 is composed of a slewing bearing and a servo motor, and the gear on the slewing bearing is meshed with the gear installed on the servo motor to drive the turntable to rotate. The tray 223 is installed at the top of the ball screw of the lifting component 221, and is connected to the slewing bearing in the rotating component 222 to be driven and pulled by the lifting and rotating mechanism 22. The supporting mechanism 23 installed on the tray 223 is responsible for carrying items such as sheet metal coils 100. The pallet 223 can also be designed into different shapes and sizes as needed to adapt to corresponding requirements. For example, an anti-slip pad or an adsorption device can be set on it, or the contour of the support mechanism 23 that contacts the sheet metal coil 100 can be made into a concave arc shape, so that the placed sheet metal coil 100 can be stably positioned on the support mechanism 23 during transportation.

[0043] See also Figure 5 In one embodiment, the oiling mechanism 5 pulls the oiling rollers 52 disposed opposite to each other through the pressing assembly 51 to roll and contact the sheet metal coil 100 passing through the oiling mechanism 5 .

[0044] Specifically, the oiling mechanism 5 applies an oil layer to the sheet metal sheet through its oiling roller 52 during the production process to ensure the uniformity and efficiency of the oiling. The oiling roller 52 applies oil to the surface of the sheet metal sheet through rolling contact with the sheet metal sheet, which prevents rust and reduces friction during the processing and forming process. The sheet metal coil 100 passes through the gap between the upper and lower oiling rollers 52. The upper oiling roller 52 uses a pneumatic clamping device to press the sheet with constant force. When the roller rotates, the oil is evenly applied to the upper and lower surfaces of the coil, and the sheet metal coil is automatically and evenly oiled to avoid manual intervention and protect the mold edge. The excess oil will drip and then flow into the oil supply barrel through the reflux pipe 53.

[0045] See also Figure 6 and Figure 7 In one embodiment, the material transfer robot 7 is installed on the forming mold 61 of the punch press 6 through the avoidance transfer mechanism 71, and the material picking robot 72 extends into the positioning mechanism 62 of the forming mold 61 to transfer the formed sheet.

[0046] Specifically, in the stamping and forming process, the punch press 6 is used to punch the sheet metal coil 100 into a specific shape through a die. The punch press 6 can also realize blanking, forming or other multi-process verification dies, and then the formed sheet metal is taken out from the forming die 61 by the transfer and unloading manipulator 7 and sent to the next station or storage area. In other words, the transfer and positioning of the sheet metal can be realized in the die, and the automatic detection of misalignment and abnormal shutdown can be realized. The punch press 6 stamps the metal sheet through the forming die 61. The forming die 61 is usually provided with a positioning mechanism 62 to ensure the accurate position of each sheet metal, so as to ensure the stamping quality. For example, the floating positioning block is moved up and down to push the sheet metal into the card slot of the positioning block to achieve positioning, and the floating positioning block is provided with a protrusion on one side, which is convenient for movement and can also reduce the gap between the sheet metal and the positioning block to avoid offset. Then the material taking manipulator 72 extends into the positioning mechanism 62 in the forming die 61, grabs the formed sheet metal, and transfers it to the specified position. During operation, the transfer and unloading manipulator 7 needs to avoid the forming die 61 of the punch press 6 by avoiding the transfer mechanism 71 to avoid collision between the manipulator and the die. A composite mechanical structure can be formed between the material taking manipulator 72 and the transfer mechanism 71.

[0047] See also Figure 8The present invention also provides a method for producing small sheet metal parts, including: transferring the sheet metal coil 100 in the temporary storage 1 to the feeding tray 3 for positioning through the loading vehicle 2; flattening the sheet metal coil 100 conveyed by the feeding tray 3 into a sheet through the flattening mechanism 4; rolling and contacting the sheet through the oiling mechanism 5 and oiling it, and then feeding it into the blanking die of the punch press 6 for forming; transferring the formed part through the loading and unloading robot 7, and repeating the steps of flattening, oiling and blanking when the sheet metal coil 100 is not used up, and performing the step of loading and positioning when the sheet metal coil 100 is used up.

[0048] Specifically, in an embodiment of the present invention, the sheet metal coil 100 in the coil temporary storage 1 is carried by the loading vehicle 2, i.e., the coil loading vehicle 2, to the side of the feeding tray 3, and the sheet metal coil 100 is clamped and positioned on the feeding turntable. After the sheet metal coil 100 is transferred to the feeding tray 3 and positioned, the sheet metal coil 100 is manually unrolled, and the sheet metal coil 100 is fed into a flattening mechanism 4, such as a flattener, and the coil is flattened by the flattener. The flattener equipment flattens strips or plates of a certain thickness through the extrusion of upper and lower rollers. The flattener has various structural forms, generally based on the arrangement of "four on top and five on bottom" or "three on top and four on bottom", and is equipped with transfer rollers at the front and back, and the flattening thickness accuracy can be finely adjusted through a handle at the top. Then the flattened sheet product enters the oiling mechanism 5, which is an automatic oiling machine. The sheet of the sheet metal coil 100 passes through the gap between the upper and lower oiling rollers 52. The upper oiling roller 52 uses a pneumatic clamping device to constantly clamp the sheet. When the roller rotates, the oil is evenly applied to the upper and lower surfaces of the coil. After the coil passes, it is sent to the blanking die of the punch press 6. Whenever the punch press 6 works once, the die automatically blanks and positions itself, and the forming die 61 blanks and forms the sheet. The material taking manipulator 72 of the automatic transfer and unloading manipulator 7 grabs the semi-finished product and the finished product and transfers them to a workstation or unloads them, and then withdraws to avoid the working area of ​​the punch press 6. When the coil is not used up, the actions of oiling, unloading and transferring are repeated to realize the cycle and work automatically. When the coil is used up, it stops working after being detected by the lack of material sensor, and repeats the action of the loading car 2 positioning the sheet metal coil 100 to the feeding tray 3 to realize the cycle and work automatically.

[0049] See also Figure 8 In one embodiment, the step of transferring the sheet metal coil 100 in the temporary storage 1 to the feeding tray 3 for positioning by the loading vehicle 2 includes: the loading vehicle 2 sequentially selects the first direction driving wheel 211 and the second direction driving wheel 212 from the first position to move to the second position in the temporary storage 1, and carries the sheet metal coil 100 back to the first position through the supporting structure; the loading vehicle 2 selects the second direction driving wheel 212 from the first position to move to the third position next to the feeding tray 3, matches the height position of the feeding tray 3 through the supporting mechanism 23, and selects the first direction driving mechanism to move to the fourth position where the sheet metal coil 100 is loaded on the feeding tray 3 for positioning.

[0050] Specifically, in the embodiments of the present invention, please refer to Figure 2 , the sheet metal coil 100 is stored in the coil temporary storage 1, the loading vehicle 2 selects the first direction driving wheel 211, that is, it automatically moves forward and backward to the corresponding position 1, and then the loading vehicle 2 selects the second direction driving wheel 212, that is, the left and right direction wheel, to lift up and contact the ground, so that the first direction driving wheel 211, that is, the wheel in the forward and backward movement direction, is off the ground. The loading vehicle 2 then moves left and right to the position 2 where the supporting mechanism 23 can take down the sheet metal coil 100, and the lifting and rotating mechanism 22 lifts up the supporting mechanism 23, and the sheet metal coil 100 is covered on the supporting mechanism 23, and the supporting mechanism 23 is lowered to the initial position. The loading vehicle 2 then moves left and right back to position 1, completing the material collection of the sheet metal coil 100. Then the loading car 2 moves forward and backward to the position 3 next to the coil tightening and positioning feeding turntable, and the rotating lifting mechanism rotates to the position where the empty supporting mechanism 23 is positioned on the feeding tray 3 opposite the sheet metal coil 100. The loading car 2 then moves left and right to the position 4 where the supporting mechanism 23 can take off the coil, and the rotating lifting mechanism lifts it up to make the empty coil leave the positioned feeding tray 3. After exiting, switch to the side carrying the sheet metal coil 100 to load the coil to the feeding tray 3 where the coil is tightened and positioned, and after the sheet metal coil 100 is placed, the positioning of the sheet metal coil 100 is completed, and finally the loading car 2 moves to a safe position to reset.

[0051] In summary, the present invention provides a small sheet metal parts production line and production method, which accurately arranges the process equipment in the transfer area, processing area and forming area, and combines the process equipment such as a loading trolley, a feed tray, a flattening mechanism, an oiling mechanism, a punching machine and a transfer and unloading robot to form a production line. The loading trolley is used to position and assemble the sheet metal coil on the feed tray, and the sheet metal coil is processed by the flattening mechanism and the oiling mechanism. After the punching machine blanks and forms the sheet metal, the formed parts are removed by the transfer and unloading robot, thereby realizing automated production optimization and collaboration, reducing manual operations, improving overall production efficiency, reducing labor costs, and ensuring the stability of the quality of sheet metal products.
