Description

Technical Field

[0001] This invention relates to the field of stamping technology, and more particularly to a stamping workshop equipped with a gantry robot. Background Technology

[0002] Stamping, as a fundamental process in manufacturing, is widely used in numerous fields such as automobiles, home appliances, and electronics. With industrial upgrading and the development of intelligent manufacturing, the level of automation and intelligence in stamping workshops has become a key indicator for measuring a company's manufacturing capabilities.

[0003] Traditional stamping workshops use 8-ton forklifts for sheet metal storage and assembly. Forklift aisles occupy a large area, and the mold storage area is far from the stamping line. Mold changes take a long time. Furthermore, current solutions for delivering stamped parts off-line and into the warehouse mostly involve forklifts or AGVs combined with forklifts. Warehouse access using forklifts or AGVs requires reserved aisles, resulting in warehouse usable area being only about 50% of the total area. In other words, existing stamping workshops, due to the need for forklift aisles, the distance between the mold storage area and the stamping line, and the need for multiple personnel for warehousing and retrieving stamped parts, result in low area utilization and long mold changeover times, leading to low efficiency.

[0004] Therefore, there is an urgent need for a stamping workshop equipped with gantry robots to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a stamping workshop with a gantry robot to solve the problems of low area utilization, long mold change time, low efficiency, and the need for multiple forklift operators and heavy workload in the existing stamping workshop.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A stamping workshop with a gantry robot includes a workshop body and a gantry robot, a stamping production line, a die storage warehouse, a sheet metal warehouse, and a finished product warehouse located within the workshop body. The gantry robot can pick up and place workpieces. The stamping production line can stamp the workpieces to be processed. The die storage warehouse is used to store dies. The sheet metal warehouse is used to store unprocessed workpieces. The finished product warehouse is used to store processed workpieces. There are two die storage warehouses, which are symmetrically arranged on both sides of the stamping production line along the length of the workshop body. A sheet metal warehouse is located at one end of each die storage warehouse, and a finished product warehouse is located at the other end of each die storage warehouse. The gantry robot includes an end effector and a structural frame. The end effector is located above the interior of the workshop body and is slidably disposed on the structural frame. The end effector can move along the length, width, and height of the workshop body, respectively.

[0008] Furthermore, at the other end of each of the two mold storage warehouses, there are multiple finished product warehouses, which are arranged along the length of the workshop body.

[0009] Furthermore, along the length of the workshop body, a plurality of finished product warehouses are evenly spaced within the workshop body.

[0010] Furthermore, the stamping workshop equipped with the gantry robot is also equipped with a material receiving belt mechanism. Along the length of the workshop body, the material receiving belt mechanism is connected to the stamping production line, and the finished product warehouse is set on both sides of the material receiving belt mechanism.

[0011] Furthermore, the finished product warehouse extends along the width of the workshop body.

[0012] Furthermore, the finished product warehouse includes multiple layers of pallets, and the spacing between adjacent pallets in the height direction of the workshop body is 200mm-500mm.

[0013] Furthermore, a mobile trolley is provided between each of the two mold storage warehouses and the stamping production line.

[0014] Furthermore, one of the mold storage warehouses is used to replace some of the molds on the stamping production line, and the other mold storage warehouse is used to replace another part of the molds on the stamping production line.

[0015] Furthermore, the workshop body has a material inlet and a material outlet. The material inlet is located on the side of the sheet metal warehouse away from the mold storage warehouse, and the material outlet is located on the side of the finished product warehouse away from the mold storage warehouse.

[0016] Furthermore, multiple discharge ports are provided, and the multiple discharge ports are symmetrically arranged within the workshop body along the width direction of the workshop body.

[0017] The beneficial effects of this invention are:

[0018] This invention provides a stamping workshop with a gantry robot, including a workshop body and a gantry robot, a stamping production line, a mold storage warehouse, a sheet metal warehouse, and a finished product warehouse located within the workshop body. The gantry robot can pick up and place workpieces, the stamping production line can stamp workpieces to be processed, the mold storage warehouse is used to store molds, the sheet metal warehouse is used to store unprocessed workpieces, and the finished product warehouse is used to store processed workpieces. There are two mold storage warehouses, which are symmetrically arranged on both sides of the stamping production line along the length of the workshop body. A sheet metal warehouse is set at one end of each mold storage warehouse, and a finished product warehouse is set at the other end of each mold storage warehouse. The gantry robot includes an end effector and a structural frame. The end effector is located above the interior of the workshop body and is slidably mounted on the structural frame. The end effector can move along the length, width, and height of the workshop body, respectively. With the above setup, two mold storage bins are symmetrically positioned on both sides of the stamping production line, reducing the distance between the mold storage bins and the stamping production line. This reduces the time required for mold changes and improves overall production efficiency. The end effector is located above the interior of the workshop body and can move along the length, width, and height of the workshop body to perform loading of workpieces to be processed, unloading of processed workpieces, and unloading of processed workpieces from the finished product warehouse. This eliminates the need for forklift lanes and the need to reserve lanes for AGV entry, thus improving the area utilization of the stamping workshop with gantry robots. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0025] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0028] This embodiment provides a stamping workshop with a gantry robot, which reduces the time required to change molds, improves overall production efficiency, and increases the area utilization rate of the stamping workshop with the gantry robot.

[0029] like Figures 1-2As shown, in this embodiment, the stamping workshop with a gantry robot includes a workshop body and a gantry robot 1, a stamping production line 2, a mold storage warehouse 3, a sheet metal warehouse 4, and a finished product warehouse 5 located within the workshop body. The gantry robot 1 can pick up and place workpieces, the stamping production line 2 can stamp the workpieces to be processed, the mold storage warehouse 3 is used to store molds, the sheet metal warehouse 4 is used to store unprocessed workpieces, and the finished product warehouse 5 is used to store processed workpieces. There are two mold storage warehouses 3, which are symmetrically arranged on both sides of the stamping production line 2 along the length of the workshop body. A sheet metal warehouse 4 is provided at one end of each mold storage warehouse 3, and a finished product warehouse 5 is provided at the other end of each mold storage warehouse 3. The gantry robot 1 includes an end effector 11 and a structural frame. The end effector 11 is located above the interior of the workshop body and is slidably disposed on the structural frame. The end effector 11 can move along the length direction, width direction, and height direction of the workshop body, respectively. Understandably, through the above setup, the two mold storage bins 3 are symmetrically arranged on both sides of the stamping production line 2, reducing the distance between the mold storage bins 3 and the stamping production line 2. This reduces the time required for mold changes and improves overall production efficiency. The end effector 11 is located above the interior of the workshop body and can move along the length, width, and height of the workshop body to perform operations such as loading workpieces to be processed, unloading processed workpieces, and retrieving processed workpieces from the finished product warehouse 5. This eliminates the need for forklift lanes and reserved lanes for AGV entry, improving the area utilization of the stamping workshop with gantry robots. Furthermore, the two sheet metal warehouses 4 are symmetrically arranged on both sides of the stamping production line 2, facilitating loading.

[0030] Furthermore, this embodiment, by setting up a gantry robot 1, eliminates the need for forklifts for loading and unloading workpieces, reducing the number of forklift operators and facilitating increased automation in the stamping workshop equipped with the gantry robot. Additionally, the two mold storage bins 3 are symmetrically positioned on both sides of the stamping production line 2, allowing for simultaneous mold changes on both bins, further improving mold change efficiency and facilitating small-batch production.

[0031] Furthermore, it is conceivable that increasing the area utilization rate of a stamping workshop equipped with gantry robots can reduce the initial civil engineering investment costs. By coordinating the gantry robot 1 with the internal layout of the workshop, unmanned operations can be achieved for workpiece loading, post-processing workpiece warehousing / removal / inventory counting, reducing safety hazards for personnel in stamping workshops equipped with gantry robots.

[0032] For example, one mold storage library 3 is used to replace some molds on the stamping production line 2, and the other mold storage library 3 is used to replace another portion of the molds on the stamping production line 2. That is, both mold storage libraries 3 can simultaneously replace molds on the stamping production line 2, improving the efficiency of mold replacement. Taking a workpiece requiring five processing steps in this embodiment as an example, one mold storage library 3 replaces the molds used in three of the processing steps, and the other mold storage library 3 is used to replace the molds used in the remaining two processing steps, and these processes can be performed simultaneously. Of course, the specific number of molds replaced by the two mold storage libraries 3 can be determined according to actual usage requirements, and this embodiment does not impose a specific limitation.

[0033] Furthermore, mobile trolleys are installed between the two mold storage areas 3 and the stamping production line 2. Understandably, the mold storage areas are located on both sides of the stamping production line 2, with one mobile trolley on each side to allow for simultaneous mold replacement from both sides, further improving replacement efficiency.

[0034] Furthermore, multiple finished product warehouses 5 are provided at the other end of each of the two mold storage warehouses 3, and these warehouses 5 are arranged along the length of the workshop body. It is understandable that providing multiple finished product warehouses 5 facilitates the categorized storage of different types of workpieces.

[0035] Furthermore, multiple finished product warehouses 5 are evenly spaced within the workshop body along its length. It is understood that the evenly spaced arrangement of multiple finished product warehouses 5 within the workshop body facilitates the entry and exit of processed workpieces and makes it easier to count the workpieces.

[0036] Furthermore, such as Figure 1 As shown, the stamping workshop equipped with the gantry robot also includes a receiving conveyor belt mechanism 7. Along the length of the workshop body, the receiving conveyor belt mechanism 7 is connected to the stamping production line 2, and finished product warehouses 5 are located on both sides of the receiving conveyor belt mechanism 7. It can be understood that the receiving conveyor belt mechanism 7 connects to the stamping production line 2 to collect and transfer the finished workpieces processed on the stamping production line 2, transferring them to the finished product warehouses 5. This facilitates the end effector 11 to continue the warehouse operation of the finished workpieces processed on the receiving conveyor belt mechanism 7, transferring them to the finished product warehouses 5. Figure 1 The part highlighted by the dashed line is the stamping production line 2 and the receiving belt mechanism 7. The receiving belt mechanism 7 can be a mature product on the market, and its specific type will not be described in this embodiment.

[0037] Furthermore, the finished product warehouse 5 extends along the width of the workshop body. It is understandable that, in the width direction of the workshop body, since no other structure needs to be set between the end of the finished product warehouse 5 away from the receiving conveyor belt mechanism 7 and the workshop body, extending the finished product warehouse 5 along the width direction of the workshop body facilitates the improvement of the area utilization rate of the stamping workshop with gantry robots.

[0038] Furthermore, the finished product warehouse 5 includes multiple layers of pallets, with a spacing of 200mm-500mm between adjacent pallets along the height of the workshop body. It can be understood that 200mm is the minimum safe operating height reserved for the end effector of the gantry robot (such as a suction cup or robotic arm) when grasping and placing pallets. The 200mm baseline ensures that mechanical movements are not interfered with. Meanwhile, the 500mm upper limit, while ensuring safety, maximizes the number of stacking layers to achieve maximum storage density per unit projected area, thus improving the space utilization of the stamping workshop with gantry robots. In this embodiment, the finished product warehouse 5 includes 5 layers of pallets, providing the necessary rigidity for the pallets and columns to prevent deformation or instability due to excessive layer height under multi-layer stacking.

[0039] In this embodiment, the stamping workshop equipped with a gantry robot adopts a solution of vision positioning + gantry robot (end effector 11), which can realize the unloading of workpieces and the stacking of pallets. The pallet handling is carried out by the gantry robot, and the outbound handling of the processed workpieces is also carried out by the gantry robot.

[0040] In this embodiment, the finished product warehouse 5 is also equipped with an automatic bar picking device. By setting up the automatic bar picking device, pallets can be "freely accessed" in three-dimensional space, replacing the manual bar picking in traditional warehousing. The automatic bar picking device is a composite mechanism of "rotary gripping + linear pushing", which can be integrated into the top or bottom of each support column. After the end effector 11 grabs the pallet of parts, it can be directly transported to the storage position that is immediately constructed by the bar picking, without any manual intervention. This facilitates the realization of the goal of "unmanned warehousing / outbound / inventory" and completely eliminates the safety hazards of forklift operation. The automatic bar picking device includes a positioning and moving mechanism, which is composed of a high-precision linear module or gear rack driven by a servo motor. It is responsible for moving quickly and accurately to the target layer height position in the vertical direction of the column. The bar picking operation of the automatic bar picking device is as follows: the robotic arm moves to the bar bin, then the gripper grabs a single bar or a group of bars, then moves to the target pallet layer, aligns with the pallet positioning hole, then inserts vertically to the specified depth, and then the gripper releases and returns. The automatic bar-picking device operates as follows: the robotic arm positions itself at the bar location on the target pallet layer, then the grippers / suction cups secure the bar, apply an upward pulling force to pull it out, and then move it to the bar recycling area / new pallet location before releasing it. This automatic bar-picking device replaces manual labor, increasing speed by 3-5 times, reducing manpower requirements, lowering labor intensity, and avoiding workplace injury risks. Since this is existing technology, its specific principles will not be elaborated upon in this embodiment.

[0041] Furthermore, the workshop body has a feed inlet and a discharge outlet. The feed inlet is located on the side of the sheet metal storage 4 away from the mold storage 3, and the discharge outlet is located on the side of the finished product storage 5 away from the mold storage 3. It is understood that the feed inlet and discharge outlet are located at different ends of the workshop body along its length, with the feed inlet located on the side of the sheet metal storage 4 away from the mold storage 3 for easy feeding, and the discharge outlet located on the side of the finished product storage 5 away from the mold storage 3 for easy unloading from the finished product storage 5.

[0042] Furthermore, multiple discharge ports are provided, symmetrically arranged within the workshop body along its width. The multiple discharge ports facilitate material discharge from different finished product warehouses 5, improving the convenience of material handling.

[0043] In this embodiment, a gantry robot is applied to the stamping workshop, replacing traditional logistics solutions such as forklifts and AGVs. This improves the area utilization rate of the stamping workshop with gantry robots, significantly saving space. Mold changeover time can be reduced by approximately 40%, from 75 minutes to 45 minutes. Batch sizes on stamping production line 2 can be reduced by approximately 40%. Furthermore, it reduces labor costs and allows for a reduction in the number of forklift operators (8 per shift), achieving unmanned operation of the workshop, improving overall workshop safety, and separating human and machine workflows to avoid overlapping paths that could cause injury. It also reduces the number of production batches for each part in the stamping workshop with gantry robots, thus lowering inventory costs.

[0044] In this embodiment, the gantry robot 1 includes an end effector 11 and a structural frame. Essentially, it is a Cartesian coordinate robot that performs precise, high-speed linear motion in three-dimensional space to grasp, transport, and store materials. Commercially available products can be used. The specific type can be determined based on actual usage requirements; this embodiment does not impose any specific limitations.

[0045] Furthermore, the stamping workshop equipped with gantry robots is also equipped with a scrap room 6, which is located at one end of the workshop body in the width direction of the workshop body and is used to temporarily store scrap.

[0046] Furthermore, the stamping workshop equipped with gantry robots also includes a mold repair area. Located at the end of one of the mold storage areas 3 furthest from the stamping production line 2, this area is used to repair damaged molds. In this embodiment, the scrap room 6 is located at one end of the workshop body, and the mold repair area is located at the other end.

[0047] In this embodiment, taking the workpiece as a sheet metal as an example, refer to... Figure 1 The working process of the stamping workshop with the gantry robot described above, in the direction of the middle arrow, is as follows:

[0048] First, the sheet metal is stored in the sheet metal warehouse 4. Then, the end effector 11 is used to load multiple sheet metals and move them to the stamping production line 2.

[0049] Then, stamping production line 2 stamps multiple sheets. After stamping, the stamped parts (the processed sheets) are transferred to the receiving belt mechanism 7 and moved to the finished product warehouse 5. Then, the end effector puts the stamped parts into the warehouse and transports them to the finished product warehouse 5.

[0050] When it is necessary to release the stamped parts from the finished product warehouse 5, simply release the stamped parts. When it is necessary to change the mold, simply change the mold. Otherwise, the above steps can be repeated to process the stamped sheet material.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
