[0017] The working principle of this technical solution is:

[0018] ①The high pressure process in the pipe is as follows:

[0019] (1) Place a number of beams and longitudinal arms in the corresponding storage racks, start the driving assembly, and the driving assembly drives the conveyor belt to rotate. The conveyor belt rotates the beams or longitudinal arms, so that they enter the inclined storage table in turn and roll down under the action of gravity until they contact the first limit block. Start the driving member, and the driving member drives the single-tube transport member to rotate. One side of the single-tube transport member rises and lifts the lowest beam or longitudinal arm. The beam or longitudinal arm rolls along the single-tube transport member to the second limit block. Then start the transverse moving member, and the transverse moving member drives the two sets of driving blocks to approach each other until they abut against the two ends of the beam or longitudinal arm. Then start the rotating member, and the rotating member drives the driving block to rotate, and the driving block drives the beam or longitudinal arm to rotate. In this process, the recognition component will recognize the weld on the beam or longitudinal arm until the weld rotates to the specified position, the rotating member stops rotating, and the transverse moving member drives the two sets of driving blocks to move away from each other. Start the clamping structure, and the clamping structure clamps the longitudinal arm on the single-tube transport member to the pipe bending machine for processing. The first robot transports the crossbeam and the longitudinal arm processed by the tube bender to the placement table.

[0020] (2) The second robot transports the crossbeam and longitudinal arm on the placement table to the mold of the first press unit for preforming, and the third robot transports the preformed pipe in the first press unit to the second press unit for internal high-pressure bulging.

[0021] (3) The fourth robot transfers the cross beam and longitudinal arm that have been finally formed by internal high pressure from the second press to the position of the laser coding structure for laser coding. After coding, they are released to the third conveying mechanism for transportation and then transported to the manual picking point for framing. At this point, the internal high pressure production of the pipe completes a working cycle, and continuous batch production repeats the cycle.

[0022] ②The liquid cooling plate stamping process is as follows:

[0023] (1) Workers stack the liquid cooling plates on the base and limit them with limit columns. When the fifth robot transports the liquid cooling plates, it uses a pneumatic sheeting device to complete the plate disassembly and is equipped with a double material detection device to prevent stacking. The fifth robot transfers the liquid cooling plates to the first conveying mechanism. During the conveying process of the first conveying mechanism, the oiling machine oils the liquid cooling plates. The oiled liquid cooling plates are transferred to the second conveying mechanism, and the centering machine centers the liquid cooling plates on the second conveying mechanism. The centered liquid cooling plates are transferred to the transmission end of the second conveying mechanism.

[0024] (2) The fourth robot transports the aligned liquid cooling plate to the second press unit for calendering, the third robot transports the liquid cooling plate calendered by the second press unit to the first press unit for trimming and punching, and the second robot transports the liquid cooling plate after trimming and punching in the first press unit to the fourth transport mechanism.

[0025] (3) The fourth conveying mechanism conveys the liquid cooling plate to the top of the lifting device. The lifting member drives the lifting plate to move upward, and the lifting plate drives all the lifting columns to move upward and insert from the spacing of the conveyor. The lifting columns drive the liquid cooling plate to move upward, and the workers deburr the liquid cooling plate. After the processing is completed, the first conveying member and the second conveying member are started, driving the first conveying roller and the second conveying roller to move, so that the liquid cooling plate is transferred to the top of the second conveying roller and is located in the flipping device. The flipping member is started, and the flipping member drives the roller to rotate, and the roller drives the flipping frame to flip, thereby realizing the flipping of the liquid cooling plate. The second conveying member is started, and the second conveying member drives the second conveying roller to rotate, thereby transferring the liquid cooling plate to the fifth conveying mechanism, and the workers deburr the other side of the liquid cooling plate, and finally frame it. At this point, a working cycle of the liquid cooling plate is completed.

[0026] When replacing a molded product, it is necessary to switch the control program of the control unit, replace the robot's end picker and auxiliary hardware tooling (such as molding molds, etc.).

[0027] The beneficial effects of this technical solution are:

[0028] ① The main problem solved by the present invention is that the current automatic production line for high-pressure forming of pipes can only meet the needs of a single high-pressure forming process and mass production, and is not compatible with other different types of forming processes and production requirements. This production line effectively integrates the high-pressure forming process of pipes and the liquid-cooled plate stamping forming process, and develops a set of automated mass production line solutions that are compatible with the two forming processes of tubes and plates. Compared with the two production lines, the investment cost is reduced (can be reduced by more than 60%) and the floor space is reduced (can be reduced by more than 50%).

[0029] ②The pipe loading unit can automatically load pipes, and can lift and transport the pipe at the bottom of the inclined storage table with a single pipe transport structure to achieve the extraction of a single pipe. And by setting a weld identification structure, the weld on the pipe can be rotated to the set position, which is convenient for the robot end picker to grab and facilitate subsequent production.

[0030] ③ The pneumatic sheet separation device is used to complete the sheet disassembly, and a double material detection device is configured to prevent the phenomenon of overlapping materials. The centering unit is used to adjust the centering position of the liquid cooling plate to prepare for the fourth robot to grab and load the material.

[0031] ④ In this technical solution, by providing a lifting device, the liquid cooling plate on the fourth conveying mechanism can be lifted to separate it from the fourth conveying mechanism, and the lifted liquid cooling plate is convenient for workers to manually deburr. A sixth conveying mechanism is provided above the lifting column, which can automatically convey the liquid cooling plate to the flipping device. The flipping device can automatically flip and convey the liquid cooling plate, and the flipped liquid cooling plate is conveyed to the fifth conveying mechanism through the seventh conveying mechanism for manual deburring. The entire conveying process does not require human participation. BRIEF DESCRIPTION OF THE DRAWINGS

Start the driving member, and the driving member drives the single-tube transport member 24 to rotate. One side of the single-tube transport member 24 rises and lifts the lowest beam or longitudinal arm. The beam or longitudinal arm rolls along the single-tube transport member 24 to the second limit block 25. Then start the transverse moving member, and the transverse moving member drives the two groups of drive blocks to approach each other until they abut against the two ends of the beam or longitudinal arm. Then start the rotating member, and the rotating member drives the drive block to rotate, and the drive block drives the beam or longitudinal arm to rotate. In this process, the recognition component will recognize the weld on the beam or longitudinal arm until the weld rotates to the specified position, the rotating member stops rotating, and the transverse moving member drives the two groups of drive blocks to move away from each other. The clamping structure 16 is activated, and the clamping structure 16 clamps the longitudinal arm on the single tube transport member 24 to the tube bender 17 for processing. The first robot 10 transports the crossbeam and the longitudinal arm processed by the tube bender 17 to the placement table 18.

[0055] (2) The second robot 11 transports the crossbeam and longitudinal arm on the placement table 18 to the mold of the first press unit 3 for preforming, and the third robot transports the preformed pipe in the first press unit 3 to the second press unit 4 for internal high-pressure bulging.

[0056] (3) The fourth robot 12 transfers the cross beam and longitudinal arm that have been finally formed by internal high pressure from the second press to the position of the laser coding structure 36 for laser coding. After coding, they are released to the third conveying mechanism 37 for conveying and then conveyed to the manual picking point for framing. At this point, the internal high pressure production of the pipe completes a working cycle, and continuous batch production repeats the cycle.

[0057] ②The liquid cooling plate stamping process is as follows:

[0058] (1) Workers stack the liquid cooling plates on the base and limit them with the limit columns 31. When transporting the liquid cooling plates, the fifth robot 13 completes the disassembly of the plates through a pneumatic sheeting device, and is also equipped with a double material detection device to prevent stacking. The fifth robot 13 transfers the liquid cooling plates to the first conveying mechanism 32. During the conveying process of the first conveying mechanism 32, the oiler 33 will oil the liquid cooling plates. The oiled liquid cooling plates are transferred to the second conveying mechanism 34, and the centering machine 35 centers the liquid cooling plates on the second conveying mechanism 34. The centered liquid cooling plates are transferred to the transmission end of the second conveying mechanism 34.

[0059] (2) The fourth robot 12 transports the aligned liquid cooling plate to the second press unit 4 for calendering, the third robot transports the liquid cooling plate calendered by the second press unit 4 to the first press unit 3 for trimming and punching, and the second robot 11 transports the liquid cooling plate after trimming and punching in the first press unit 3 to the fourth conveying mechanism 38.

[0060] (3) The fourth conveying mechanism 38 conveys the liquid cooling plate to the top of the lifting device 39. The lifting member drives the lifting plate to move upward, and the lifting plate drives all the lifting columns to move upward and insert from the spacing of the conveyor. The lifting columns drive the liquid cooling plate to move upward, and the workers deburr the liquid cooling plate. After the processing is completed, the first conveying member and the second conveying member are started, driving the first conveying roller and the second conveying roller to move, so that the liquid cooling plate is transferred to the top of the second conveying roller and is located in the flipping device 41. The flipping member is started, and the flipping member drives the roller 47 to rotate, and the roller 47 drives the flipping frame to flip, thereby realizing the flipping of the liquid cooling plate. The second conveying member is started, and the second conveying member drives the second conveying roller to rotate, thereby transferring the liquid cooling plate to the fifth conveying mechanism 42, and the workers deburr the other side of the liquid cooling plate, and finally frame it. At this point, a working cycle of the liquid cooling plate is completed.
