Description

Technical Field

[0001] This application relates to the field of sheet metal processing, and in particular to an intelligent automatic chassis processing production line. Background Technology

[0002] A handcart, also known as a manually pushed cart, is primarily used for moving products such as circuit breakers and distribution cabinets. The chassis is the main structural element of the handcart, serving primarily to support and store the product.

[0003] During chassis production, various processes are required, such as drilling and bending. Each process requires manual transport of the chassis forming sheet metal to the workstation of each process. Then, according to the process requirements, such as drilling position and bending width, the sheet metal is moved to the drilling or bending position. The convenience and accuracy are difficult to control, which affects the compatibility of other parts assembly after the chassis is formed. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an intelligent chassis automated processing production line.

[0005] The intelligent chassis automatic processing production line provided in this application adopts the following technical solution:

[0006] An intelligent chassis automatic processing production line, the raw material of which is chassis plate, including laser-cut parts, hydraulically stamped parts, countersunk parts, bent parts and welded parts; each of the laser-cut parts, the hydraulically stamped parts, the countersunk parts and the bent parts is assigned a first transport component;

[0007] The first transport components are arranged in parallel, and the transport ranges of adjacent first transport components intersect; the first transport component includes a first robotic arm, a first placement part, and a positioning part; the first placement part is used to store the chassis plate to be processed; the positioning part is used to position the chassis plate, and the positioning part is provided with a ramp, which provides guiding positioning; both the first placement part and the positioning part are located within the transport range of the first robotic arm.

[0008] The welding process of the welded part is located after the bending process of the bent part. The welded part is assigned a second transport component, which includes a second robotic arm, a third robotic arm, and a second placement part. The second placement part is located next to the bent part and within the transfer range of the first robotic arm corresponding to the bent part. The second robotic arm and the third robotic arm are located at opposite ends of the welded part, and the second placement part is within the transfer range of the second robotic arm.

[0009] By adopting the above technical solution, the transfer ranges of adjacent first transport components intersect, allowing laser-cut parts, hydraulically stamped parts, countersunk parts, and bent parts to be sequentially transferred using their respective first transport components. The inclined guide positioning of the positioning unit ensures more precise transfer by the first robotic arm. For welded parts, the second transport component can be used to transport and weld the bent chassis plate. The second placement unit is located within the transfer range of the first and second robotic arms, enabling them to be transferred together. Compared to the processing of laser-cut parts, hydraulically stamped parts, countersunk parts, and bent parts, the welding process requires greater precision. The welding process utilizes the cooperation of the second and third robotic arms to ensure welding stability. The automatic end-of-line intersecting transport of chassis plates by the first and second transport components, along with accurate positioning by the positioning unit, saves labor costs and achieves automated production processing.

[0010] Optionally, the first robotic arm, the second robotic arm, and the third robotic arm are all equipped with grippers.

[0011] By adopting the above technical solution, the chassis plates can be clamped using fixtures, making the transfer process more stable and reducing the possibility of the chassis plates falling off during the transfer process.

[0012] Optionally, the clamp may include a vacuum suction cup or an electronic suction cup.

[0013] By adopting the above technical solution, a vacuum suction cup or electronic suction cup can be used to easily pick up and transfer the chassis plate by suction and desiccation, without the need for clamping and without damaging the surface of the chassis plate.

[0014] Optionally, the positioning part is further provided with a counterweight part and a separation part; the separation part is provided with a separation end, which passes through the positioning part and connects to the chassis plate.

[0015] By adopting the above technical solution, the counterweight unit detects whether the configuration of the chassis plates is within the error range. If two or more chassis plates are attracted to each other and transported to the positioning unit, the separation unit and the first robotic arm separate the multiple chassis plates.

[0016] Optionally, the separation part includes a drive source, a connecting frame, and a separation suction cup; the drive source is installed on the positioning part; the positioning part has a communication port; the separation suction cup is installed on the side of the positioning part away from the plane where the chassis plate is placed, and is connected to the drive source through the connecting frame, and is connected to the chassis plate through the communication port via the drive source.

[0017] By adopting the above technical solution, the drive source can drive the separation suction cup through the connecting port to move towards the positioning part through the connecting frame, and adsorb the chassis plate on the positioning part. The first robot arm will then move the uppermost chassis plate away to separate the chassis plates that are stuck together.

[0018] Optionally, the laser-cut part, the hydraulic punching part, the countersunk part, and the bending part are all provided with adjustment platforms.

[0019] By adopting the above technical solution, the position of the chassis plate on the laser-cut parts, hydraulically punched parts, countersunk parts, and bent parts can be adjusted using the adjustment table, so that the equipment at the corresponding workstation can accurately process the chassis plate.

[0020] Optionally, it may also include a grinding component; the grinding component is located behind the welded component, and the grinding component is equipped with a fourth robotic arm.

[0021] By adopting the above technical solution, the welded chassis plates can be transported to the grinding parts for grinding by the fourth robotic arm, so as to avoid welding marks such as weld beads on the welded chassis plates, which would affect the use.

[0022] Optionally, a switching table is also included; the grinding component and the fourth robotic arm are mounted on the switching table.

[0023] By adopting the above technical solution, the switching table can switch the grinding part to the end closer to the welding part or the end farther away from the welding part, so that the fourth robot can transfer the chassis plate to the grinding part or switch the grinding part to other positions through the switching table, so that the fourth robot can transfer the chassis plate to the collection point for collection.

[0024] Optionally, a testing element is provided on the switching platform; the testing end of the testing element is aligned with the welded part.

[0025] By adopting the above technical solution, the detection component can automatically detect whether the welded chassis plate needs to be ground, eliminating the need for manual observation and confirmation, thus improving the automation effect.

[0026] Optionally, a collection element is provided at the end of the switching station away from the detection element.

[0027] By adopting the above technical solution, the positions of the collection part and the grinding part can be switched via the switching table, making collection more convenient.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The transfer ranges of adjacent first transport components intersect, allowing laser-cut parts, hydraulically stamped parts, countersunk parts, and bent parts to be sequentially transferred using their respective first transport components. The chassis plates are guided and positioned by the ramp of the positioning unit, resulting in more precise transfer by the first robotic arm. For welded parts, the second transport component can be used to transport and weld the bent chassis plates. The second placement unit is located within the transfer range of the first and second robotic arms, enabling them to be transferred together. Compared to the processing of laser-cut parts, hydraulically stamped parts, countersunk parts, and bent parts, the welding process requires greater precision. The welding process utilizes the cooperation of the second and third robotic arms to ensure welding stability. The automatic handling of chassis plates via the first and second transport components, and the accurate positioning of the chassis plates controlled by the positioning unit, saves labor costs and achieves automated production processing.

[0030] 2. The fourth robotic arm can transport the welded chassis plates to the grinding section for grinding, thus avoiding weld beads and other welding marks on the welded chassis plates, which would affect their use.

[0031] 3. The switching table can switch the grinding part to the end closer to the welding part or the end farther away from the welding part, so that the fourth robot can transfer the chassis plate to the grinding part or switch the grinding part to other positions through the switching table, so that the fourth robot can transfer the chassis plate to the collection point for collection.

[0032] 4. Using a drive source, the separation suction cup can be driven through the connecting port to move towards the positioning part via the connecting frame, and the chassis plate on the positioning part will be adsorbed. The first robot arm will then move the top chassis plate away to separate the chassis plates that are stuck together. Attached Figure Description

[0046] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0047] This application discloses an intelligent chassis automatic processing production line.

[0048] An intelligent chassis automated processing production line, reference Figure 1 As shown, it includes a laser-cut part 1, a hydraulically punched part 2, a countersunk part 3, a bent part 4, and a welded part 5;

[0049] Laser-cut part 1 is made using a laser cutting machine to cut the original sheet material into the size and shape of the chassis.

[0050] refer to Figure 2 As shown, the hydraulic stamping component 2 is used to stamp embossed bulges onto the chassis sheet metal. The hydraulic stamping component 2 employs a hydraulic press, which includes a hydraulic table and a hydraulic end. The hydraulic table has a fixed groove for placing the chassis sheet metal to prevent positional shift. The hydraulic end can press against the hydraulic table, and the hydraulic end has a punching block that matches the position of the embossed bulge after chassis forming. The hydraulic table has a punching groove, the position of which matches the punching block on the hydraulic end. When the chassis sheet metal is placed in the fixed groove, the stamping position is fixed. The hydraulic end drives the punching block to press against the hydraulic table, pressing the punching block into the fixed groove and stamping the chassis sheet metal to create the embossed bulge. (The installation arrangement of the laser-cut component 1, hydraulic stamping component 2, countersunk component 3, bending component 4, and welded component 5 is similar; specific arrangements are not shown in the attached diagrams.) Figure 2 (Taking hydraulic stamping part 2 as an example)

[0051] The countersunk hole component 3 is used to punch corresponding holes in the chassis plate. The punched holes can be used for bolt fastening, pipeline routing, etc. The countersunk hole component 3 adopts a multi-axis countersunk hole machine, which mainly includes a countersunk hole machine table and a punching end. The punching end is equipped with a replaceable punching plate. The countersunk hole machine table is equipped with a replaceable through plate. The through plate has several through holes of different sizes. The punching plate is equipped with punching protrusions, and the punching protrusions correspond to the required punching positions and through holes of the chassis plate. Thus, during punching, the through holes can be passed through and punch the required holes in the chassis plate. At the same time, both the punching plate and the through plate are replaceable to adapt to other chassis plates with different punching positions.

[0052] The bending component 4 is used to bend the chassis sheet metal. The main bending points are at the corners of the chassis sheet metal. Specific corners of the chassis sheet metal are bent into a frame shape to fit the handcart to be installed. The bending component 4 can be made using a sheet metal bending machine. The sheet metal bending machine mainly includes a bending table, a bending end, and a pressing end. The bending table consists of a lifting panel and a fixed panel. There is a height difference between the lifting panel and the fixed panel, and the lifting panel can be raised and lowered to adjust the height difference. The bending end is opposite to the corner of the lifting panel. When the chassis sheet metal is placed on the lifting table, the chassis sheet metal is placed on the lifting panel, and the required bending width is adjusted. The pressing end is used to press the chassis sheet metal tightly, and then the bending end is pressed down from the corner of the lifting panel. The height difference between the lifting panel and the fixed panel is used to bend the chassis sheet metal.

[0053] Welding component 5 can weld the bent chassis plate, so that each adjacent bent edge of the chassis plate is welded and sealed to prevent the bent edge from breaking open and resetting under pressure. Welding component 5 mainly includes a welding machine and a welding station. The welding station is equipped with several limit cylinders and clamping cylinders. The limit cylinder pushes the chassis plate to the designated position, and then the clamping cylinder presses the chassis plate onto the welding station, where the welding gun on the welding machine performs welding.

[0054] Laser-cut part 1, hydraulic punching part 2, countersunk part 3, and bending part 4 are each assigned a first transport part 6. The first transport part 6 is used to transfer the chassis plate. Laser-cut part 1, hydraulic punching part 2, countersunk part 3, and bending part 4 are arranged side by side on the same horizontal plane, with a preset distance between the ends of adjacent equipment.

[0055] The first transport components 6 are arranged in parallel, and the transport ranges of adjacent first transport components 6 are connected, so that the previous group of first transport components 6 can transfer the chassis plate to the next group of first transport components 6.

[0056] The first transport component 6 includes a first robotic arm 63, a first placement part 61, and a positioning part 62; the first placement part 61 is used to store chassis plates to be processed, and the first placement part 61 may be a first placement table, which can stack and store chassis plates.

[0057] The positioning part 62 is used to position the chassis plate. The positioning part 62 can be a positioning seat. The bottom of the positioning seat is equipped with a fixed frame for load bearing. The positioning seat is equipped with several rotatable guide columns and ramps. There are two guide columns in one set. The chassis plate is limited between the two guide columns. Several sets of guide columns form the travel path of the chassis plate. During the sliding of the chassis plate along the ramp, the guide columns rotate and push to guide and position it. At the same time, the several sets of guide columns can also prevent the chassis plate from falling out of the positioning seat.

[0058] Further reference Figure 3 As shown, the positioning seat is also equipped with a counterweight 64 and a separation part 65. The counterweight 64 can be a counterweight scale, which is equipped with a pressure sensor to weigh the chassis plates.

[0059] Because the chassis plates are relatively thin, stacked chassis plates tend to stick together due to static electricity or residual water stains after cleaning. When the chassis plates are transported to the positioning seat, it is difficult to distinguish whether the chassis plates on the positioning seat are a single plate or two plates that are stuck together. Therefore, a counterweight scale can be set to detect the number of chassis plates. Specifically, the counterweight scale can be set with the weight of a single chassis plate and an error range. When a chassis plate is placed on the positioning seat, if the counterweight scale detects that the weight of the chassis plate is outside the error range, it indicates that there may be multiple chassis plates stuck together or a single chassis plate that is unqualified.

[0060] The counterweight scale can be placed below the positioning base and can be used to measure the entire positioning base together. The counterweight data needs to be deducted from the weight of the positioning base.

[0061] The separation part 65 is installed on the side of the positioning seat. The separation part 65 may include a drive source 651 and a separation suction cup 653. The drive source 651 may be an electric push rod, a cylinder, a hydraulic cylinder or other drive components. The separation suction cup 653 extends out of the connecting frame 652 and is installed on the telescopic end of the drive source 651 through the connecting frame 652. The positioning seat has a communication port. The separation suction cup 653 is located on the other side of the positioning seat away from the plane where the chassis plate is placed. The separation suction cup 653 can penetrate the communication port and be attracted to the chassis plate by the drive of the drive source 651. The separation suction cup 653 is the separation end and may be a vacuum suction cup or an electronic suction cup.

[0062] Specifically, when the counterweight scale detects that the weight of the chassis plate is outside the error range, the telescopic end of the drive source 651 drives the separation suction cup 653 to move towards the chassis plate, so that the separation suction cup 653 adsorbs the chassis plate near the positioning seat through the connecting port. Then, the first robot arm 63 picks up the chassis plates that are stuck together to separate the two chassis plates that are adsorbed together. If multiple chassis plates are adsorbed together, the first robot arm 63 repeatedly picks up the chassis plates until the counterweight scale detects that the weight of the chassis plate is within the error range.

[0063] When the counterweight scale detects that the weight of the chassis plate is within the error range, the separation suction cup 653 releases the chassis plate, allowing the first robotic arm 63 to pick up the chassis plate and move it to the corresponding processing station.

[0064] The separation part 65 is located at the end of the positioning seat, that is, at one end of the chassis plate after the ramp guide is completed. Therefore, when separating the mutually adsorbed chassis plates, the separation is performed after positioning, so that the first robot arm 63 can directly pick up the chassis plate to the corresponding processing station without repeating the positioning.

[0065] The first robotic arm 63 is used to pick up and transfer the chassis plate. The first placement table and the positioning seat are both located within the transfer range of the first robotic arm 63. Therefore, the first robotic arm 63 can pick up the chassis plate from the first placement table to the positioning seat. The positioning seat then performs ramp positioning to ensure that the angle and position of the chassis plate are accurate. Finally, the first robotic arm 63 picks up and places the chassis plate on the designated workstation. The designated workstation is the processing workstation corresponding to the laser-cut part 1, the hydraulic punching part 2, the countersunk part 3, and the bending part 4.

[0066] Since the transfer ranges of two adjacent first transport pieces 6 are connected, the first set of first robotic arms 63 can transfer the chassis plate processed at the workstation to the first placement platform corresponding to the next workstation, so that the next set of first robotic arms 63 can pick up and transport it.

[0067] Specifically, the sheet material is piled on the first placement table corresponding to the laser cutting part 1. The first robot 63 corresponding to the laser cutting part 1 transports the sheet material to the positioning seat corresponding to the laser cutting part 1. After the sheet material is positioned, the first robot 63 corresponding to the laser cutting part 1 transports the sheet material to the laser cutting part 1 for laser cutting. After the cutting is completed, the first robot 63 picks up the cut chassis sheet and transfers it to the first placement table corresponding to the hydraulic stamping part 2.

[0068] The first robotic arm 63 corresponding to the hydraulic stamping part 2 transports the chassis plate to the positioning seat corresponding to the hydraulic stamping part 2. After the chassis plate is positioned, the first robotic arm 63 corresponding to the hydraulic stamping part 2 transports the chassis plate to the hydraulic stamping part 2 for stamping and forming. After the stamping and forming, the first robotic arm 63 takes the stamped chassis plate and transfers it to the first placement table corresponding to the countersunk part 3.

[0069] The first robotic arm 63 corresponding to the countersunk part 3 transports the chassis plate to the positioning seat corresponding to the countersunk part 3. After the chassis plate is positioned, the first robotic arm 63 corresponding to the countersunk part 3 transports the chassis plate to the countersunk part 3 for punching and forming. After punching and forming, the first robotic arm 63 takes the punched chassis plate and transfers it to the first placement table corresponding to the bending part 4.

[0070] The first robotic arm 63 corresponding to the bending part 4 transports the chassis plate to the positioning seat corresponding to the bending part 4. After the chassis plate is positioned, the first robotic arm 63 corresponding to the bending part 4 transports the chassis plate to the bending part 4 for bending and forming. After bending and forming, the first robotic arm 63 takes the bent chassis plate and transfers it to the second placement part of the welding part 5.

[0071] The welded part 5 is equipped with a second transport part 7, which includes a second robot arm 72, a third robot arm 73, and a second placement part 71. The second placement part 71 is located next to the bending part 4 and within the transfer range of the first robot arm 63 corresponding to the bending part 4. The second placement part 71 adopts a second placement platform or a placement table. Taking the second placement platform as an example, after the bending part 4 bends the chassis plate, it is transferred to the second placement platform by the first robot arm 63 corresponding to the bending part 4.

[0072] The second robotic arm 72 and the third robotic arm 73 are located at both ends of the welding component 5, and the second placement table is located within the transfer range of the second robotic arm 72, so that the second robotic arm 72 can pick up the chassis plate from the second placement table and transfer it to the welding component 5. The welding component 5, together with the second robotic arm 72 and the third robotic arm 73, welds the bent chassis plate. The third robotic arm 73 can be equipped with a detachable welding gun.

[0073] Among them, the laser-cut part 1, the hydraulic punching part 2, the countersunk part 3, and the bending part 4 are all equipped with an adjustment platform 102. The adjustment platform 102 includes a receiving seat and a sliding seat. The sliding seat has sliding grooves in the horizontal and vertical directions on the same horizontal plane. The receiving seat can move along the sliding grooves and can be fixed by bolts after movement.

[0074] The processing position can be manually adjusted using the adjustment table 102 to accommodate chassis plates of different sizes.

[0075] The production line also includes a control box containing a controller. The first transport component 6, the second transport component 7, the laser-cut component 1, the hydraulic punching component 2, the countersunk component 3, the bending component 4, the welded component 5, the counterweight 64, and the separation component 65 are all electrically connected to the controller. The controller controls the opening and closing of these devices. Each of the first transport component 6, the second transport component 7, the laser-cut component 1, the hydraulic punching component 2, the countersunk component 3, the bending component 4, and the welded component 5 is equipped with a sensor group. The sensor group can detect the transport position by detecting the transport position. The sensor group can be a combination of photoelectric sensors, pressure sensors, etc. The sensor group is electrically connected to the controller. The sensor group detects environmental information and transmits it to the controller through electrical signals. The controller then judges the information and issues control commands to each device.

[0076] The chassis plates are transported to designated points using the first transport component 6 and the second transport component 7, eliminating the need for manual transport and improving the automation and intelligence of the equipment.

[0077] Furthermore, the first robotic arm 63, the second robotic arm 72, and the third robotic arm 73 are all equipped with grippers 101. The grippers 101 are used to grip and pick up the chassis plate. The grippers 101 have two gripping points, which grip the space on the left and right sides of the chassis plate respectively. By using multiple gripping points, the stability of the transfer is improved, and the chassis plate is prevented from falling off due to the loosening of one gripping point. It also prevents the chassis plate after being gripped by the countersunk hole from being affected by the hole and breaking.

[0078] The clamp 101 can also be a vacuum suction cup or an electronic suction cup. The chassis plate is adsorbed and transferred using the vacuum suction cup or electronic suction cup. After being transferred to the designated position, the suction cup can be released. Transferring using a vacuum suction cup or electronic suction cup is more convenient.

[0079] In some embodiments, reference Figure 4 and Figure 5 As shown, it also includes a grinding component 8, which is located after the welded component 5. The grinding component 8 is equipped with a fourth robotic arm 81. The grinding component 8 uses a grinding machine. After the chassis plate is bent and welded, obvious welding marks such as weld beads appear at the welding points, which not only affect the appearance but also cause certain safety issues. For example, when installing the handcart, the weld beads may be too sharp and pierce the workers or cut some connecting wires. Therefore, the grinding component 8 can be used to grind the weld beads and other welding marks after welding to make them smooth, maintaining both the appearance and safety of use.

[0080] The grinder may include at least two rotating wheels, and a grinding belt is fitted on the rotating wheels. The grinding belt may be thickened sandpaper that can be removed from the rotating wheels for easy replacement. One of the rotating wheels is connected to a motor, which drives the rotating wheel to rotate and drives the other rotating wheels to rotate through the grinding belt.

[0081] The transfer range of the fourth robot 81 covers the welded part 5 and the grinding part 8. Therefore, the fourth robot 81 can directly pick up the welded chassis plate to the grinding part 8. During the process of the grinding belt rotating along the rotating wheel, the welding point of the chassis plate comes into contact with the grinding belt, thereby using the rough surface of the grinding belt to smooth out the welding marks such as weld beads at the welding point.

[0082] The fourth robotic arm 81 can be the same as the first robotic arm 63, the second robotic arm 72, and the third robotic arm 73. All of them can be equipped with a gripper 101, or a vacuum suction cup or an electronic suction cup, and can be electrically connected to the controller.

[0083] Further reference Figure 6As shown, a switching platform 9 is provided at the bottom of the grinding component 8 and the fourth robotic arm 81, meaning that both the grinding component 8 and the fourth robotic arm 81 are mounted on the switching platform 9.

[0084] The switching platform 9 is a rotatable support platform, specifically including a bottom support platform and a rotating support platform 97. The rotating support platform 97 is provided with a rotating shaft 96, and the rotating support platform 97 can rotate along the bottom support platform through the rotating shaft 96. The function of the switching platform 9 is that when the worker observes that there are no weld beads or other welding marks on the chassis plate of the welded part 5 after welding, the switching platform 9 can be used to switch the grinding part 8 to the end away from the welded part 5, so that the fourth robot arm 81 can take the chassis plate off the welded part 5 without being blocked by the grinding part 8 and collecting the formed chassis.

[0085] The bottom support is equipped with a drive motor 93, which provides driving force to rotate the rotating support 97. Specifically, a gear ring and a gear 95 are used for linkage. The gear ring is mounted on the rotating shaft 96, and the gear 95 is mounted on the drive end of the drive motor 93. The gear 95 meshes with the gear ring. When the drive motor 93 drives the gear 95 to rotate, the gear 95 drives the gear ring and the rotating shaft 96 to rotate, thereby driving the rotating support 97 to rotate. By setting the gear ring and gear 95 to drive in linkage, compared with the drive motor 93 directly driving the rotating shaft 96, the rotating support 97 bears the weight through the rotating shaft 96. The drive motor 93 will not be damaged by the pressure of the rotating support 97, and the driving effect is more stable and safer.

[0086] The drive motor 93 is electrically connected to the controller, which can remotely control the start and stop of the drive motor 93. The drive motor 93 can drive the rotating platform 97 to rotate automatically along the fixed platform 98, thus eliminating the need for manual rotation and improving convenience and automation.

[0087] Furthermore, refer to Figure 6 or Figure 7 As shown, a detection component 91 is provided on the switching table 9. The detection end of the detection component 91 is aligned with the welded part 5. A rotatable rotary table can be provided on the welded part 5. The chassis plate is located on the rotary table. The limit cylinder and the clamping cylinder can limit the rotation of the rotary table. After welding is completed, the limit cylinder and the clamping cylinder release the rotary table. The third robot arm 73 can rotate the rotary table, or a rotation drive source 651, such as a motor, is provided at the bottom of the rotary table to drive the rotary table to rotate, so that the detection component 91 can detect each welding point of the chassis plate.

[0088] The detection component 91 can use a photoelectric sensor and an image sensor. Both the photoelectric sensor and the image sensor are aligned with the welded component 5. After the bending point of the chassis plate on the welded component 5 is welded, the photoelectric sensor and the image sensor synchronously collect environmental data and transmit the data to the controller through an electrical signal. The controller determines whether there are welding marks such as weld beads on the chassis plate based on the environmental data. If there are welding marks such as weld beads, the controller sends a control command to the drive motor 93. The drive motor 93 rotates the base plate 97 to rotate, so that the grinding component 8 rotates to the opposite direction of the welded component 5. The fourth robot arm 81 picks up the chassis plate and places it on the grinding component 8 for grinding.

[0089] If there are no weld beads or other welding marks, the controller sends a control command to the drive motor 93. The drive motor 93 rotates the base plate 97, causing the grinding part 8 to shift away from the welded part 5. After the two are separated, the fourth robot arm 81 will recycle the formed chassis.

[0090] The inspection piece 91 and the grinding piece 8 are located on the same side, which allows the fourth robotic arm 81 to directly transfer the grinding piece 8 for grinding when the inspection piece 91 detects weld beads, without the need to switch positions by the switching table 9, thus improving convenience.

[0091] The switching platform 9 has a collection component 92 at the end away from the detection component 91. The collection component 92 can be a collection plate, which is used to provide a place for recycling the finished chassis. The finished chassis can be stacked on the collection plate. The collection plate is equipped with limit posts to prevent the chassis plates from falling off. The switching platform 9 is used to switch the positions of the collection box and the grinding component 8 to achieve their respective functions.

[0092] The fourth robotic arm 81 and the switching table 9 are independent rotating systems. The fourth robotic arm 81 can rotate independently to the collection box or the grinding part 8, or it can rotate with the switching table 9.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
