[0026] The beneficial effects of the present invention are:

[0027] 1. In the present invention, the described marine cold storage automatic assembly production line places the cold storage assembly base on a shaking table, then starts the clamping electric push rod to drive the U-shaped plate to move, thereby driving the four clamping plates to approach each other, and fixes the cold storage assembly base. Then, the conveying motor is started to drive one of the screws to rotate, and the other screw is driven to rotate synchronously through the transmission of two sprockets. The two screws cooperate with the threads of the crossbeam and drive the moving table to move back and forth under the guidance of the slide rail. The moving table drives the shaking table to move back and forth, thereby moving the cold storage assembly base on the shaking table back and forth and transporting it. The provided manipulator can control the rotation of the rotating seat, the first joint, the second joint, and the third joint, and the telescopic effect of the telescopic cylinder to drive the clamp to move, and the clamp can be used to clamp and transport the cold storage assembly plate, and the plate is automatically assembled on the cold storage assembly base through the cooperation of multiple manipulators, and fixed;

[0028] 2. In the present invention, in the automated assembly production line for marine cold storage, after the cold storage is assembled, the mobile platform is controlled to move to the bottom of the lifting platform, and the conveying motor is controlled to stop working after the position sensor senses the positioning column, and then the electric push rod is controlled to drive the lifting plate and the lifting platform to move downward, and drive the installation plate and the suction cup to move downward, so that the suction cup is closely abutted against the top of the cold storage, and then the rotating motor is started to drive the driving gear to rotate, and the driving gear drives the first rotating drum to rotate through the engagement with the driven gear. While the first rotating drum rotates, it drives the first sliding frame and the first rotating plate to rotate synchronously, and drives the connecting column to perform a circular motion, and the connecting column drives the shaking table to shake in a circular motion, and the cooperation of the first guide rail, the second guide rail and the connecting plate prevents the shaking table from rotating itself, thereby driving the assembled cold storage on its top to shake in a circular trajectory through the shaking table, and while shaking, the suction cup is closely adsorbed on the top of the cold storage, thereby following the cold storage to shake in a circular motion, driving the installation plate and the linkage frame to move in a circular motion, and the linkage frame drives the second rotating plate, the first rotating plate, the second ... The second sliding frame, the second rotating drum and the rotating arm rotate. When the cold storage itself is deformed so that the movement trajectory above the cold storage is inconsistent with the trajectory of the mobile cabinet on the cold storage base, the linkage frame will be driven to slide on the outside of the second rotating plate, and the push plate will be driven to move upward through the contact between the rotating wheel and the push plate. The push plate drives the cross rail, the cross seat, the first annular track, the first arc seat and the linkage plate to move upward, squeeze the compression spring, and sense the pressure change through the first pressure sensor. When the cold storage is severely deformed, the linkage plate moves upward a large enough distance and presses the pause button. After the pause button is pressed, the rotating motor is controlled to stop running, thereby stopping the test work in time. If the cold storage still maintains a high rigidity during the shaking process, the top and base of the cold storage move basically the same, so that the linkage frame and the connecting column move in the same circular trajectory. At this time, the linkage frame will not slide on the outside of the second rotating plate, thereby squeezing the linkage plate. Therefore, when the first pressure sensor does not sense an obvious pressure value, it means that the cold storage has passed the test;

[0029] 3. In the present invention, the automatic assembly production line for marine cold storage drives the connecting frame and the counterweight plate to perform circular motion when the rotating arm rotates. The two counterweight plates obtain centrifugal force to move away from each other while performing circular motion, and press the pressure plate downward through the inclined rod. The pressure plate presses the second arc seat downward through the second annular track and presses through the second pressure sensor. When the second pressure sensor senses that the pressure value changes slightly, it means that the rotating arm is moving at a uniform speed and the test is carried out normally. When the pressure value sensed by the second pressure sensor changes drastically or disappears, there may be slippage between the suction cup and the cold storage, which affects the test results. It is necessary to re-debug and test again, so as to avoid the problem of inaccurate test results.

[0030] 4. In the present invention, the described marine cold storage automatic assembly production line controls the synchronous extension and retraction of the first electric push rod and the second electric push rod, thereby driving the first L rod and the second L rod to move up and down accordingly, and the first L rod drives the first rotating plate to slide in the first sliding frame through the first connecting rod, thereby driving the connecting column to move relative to the first rotating drum, and the second L rod drives the second rotating plate to slide in the second sliding frame through the second connecting rod, thereby driving the linkage frame to move relative to the second rotating drum, and ensuring that the initial distance between the linkage frame and the second rotating drum and the spacing between the connecting column and the first rotating drum are equal, so that the radius of the circular motion of the linkage frame and the connecting column is equal, ensuring smooth testing work, and the amplitude of the shaking of the shaking plate can be adjusted through the above operation, and the shaking speed of the shaking plate can be adjusted by adjusting the output speed of the rotating motor, so that the intensity of the anti-shaking test can be adjusted to meet different needs;

[0031] 5. In the present invention, the automated assembly production line for marine cold storage can perform an anti-sway test on the cold storage after the cold storage is automatically assembled, and can adjust the test intensity to ensure the assembly quality. When the cold storage is deformed during the test, the test can be stopped in time to prevent accidents. BRIEF DESCRIPTION OF THE DRAWINGS

The mobile platform 2 drives the shaking platform 3 to move forward and backward, so as to move the cold storage assembly base on the shaking platform 3 forward and backward, and the manipulator 6 is set, and the clamp 607 can be driven to move by controlling the rotation of the rotating seat 602, the first joint 603, the second joint 604, and the third joint 605 and the telescopic effect of the telescopic cylinder 606, and the clamp 607 is used to clamp and transport the cold storage assembly plate, and the plate is automatically assembled on the cold storage assembly base through the cooperation of multiple manipulators 6, and fixed;

[0068] After the cold storage is assembled, the moving platform 2 is controlled to move to the bottom of the lifting platform 5, and the conveying motor 205 is controlled to stop working after the position sensor 34 senses the positioning column 35. Then, the electric push rod 502 is controlled to drive the lifting plate and the lifting platform 5 to move downward, and the mounting plate 9 and the suction cup 901 are driven downward to make the suction cup 901 closely contact the top of the cold storage. Then, the rotating motor 33 is started to drive the driving gear 32 to rotate. The driving gear 32 drives the first rotating drum 703 to rotate by meshing with the driven gear 31. The first rotating drum 703 rotates while driving the first sliding frame 702 It rotates synchronously with the first rotating plate 701, and drives the connecting column 7 to perform circular motion. The connecting column 7 drives the shaking table 3 to shake in a circular motion, and the first guide rail 301, the second guide rail 303 and the connecting plate 302 cooperate to prevent the shaking table 3 from rotating itself, thereby driving the assembled cold storage on the top to shake in a circular trajectory through the shaking table 3. While shaking, the suction cup 901 is tightly adsorbed on the top of the cold storage, thereby following the cold storage to shake in a circular motion, driving the installation plate 9 and the linkage frame 8 to perform circular motion, and the linkage frame 8 drives the second rotating plate 801, the second sliding frame 802, The second rotating drum 803 and the rotating arm 30 rotate. When the cold storage itself is deformed so that the movement trajectory above the cold storage is inconsistent with the trajectory of the mobile cabinet on the cold storage base, the linkage frame 8 will be driven to slide on the outside of the second rotating plate 801, and the push plate 11 will be driven to move upward through the contact between the rotating wheel 10 and the push plate 11. The push plate 11 drives the cross rail 12, the cross seat 13, the first annular track 14, the first arc seat 15 and the linkage plate 16 to move upward, squeeze the compression spring 17, and sense the pressure change through the first pressure sensor 19. When the cold storage is severely deformed, the linkage frame 8 will be driven to slide on the outside of the second rotating plate 801. The moving plate 16 moves upwards a sufficient distance and presses the pause button 18. After the pause button 18 is pressed, the rotating motor 33 is controlled to stop running, thereby stopping the test work in time. If the cold storage still maintains a high rigidity during the shaking process, the top and base of the cold storage move basically the same, so that the linkage frame 8 and the connecting column 7 move in the same circular trajectory. At this time, the linkage frame 8 will not slide outside the second rotating plate 801, thereby squeezing the linkage plate 16. Therefore, when the first pressure sensor 19 does not sense an obvious pressure value, it means that the cold storage has passed the test;

[0069] By controlling the synchronous extension and retraction of the first electric push rod 706 and the second electric push rod 806, the first L rod 704 and the second L rod 804 are driven to move up and down accordingly, and the first L rod 704 drives the first rotating plate 701 to slide in the first sliding frame 702 through the first connecting rod 705, thereby driving the connecting column 7 to move relative to the first rotating cylinder 703, and the second L rod 804 drives the second rotating plate 801 to slide in the second sliding frame 802 through the second connecting rod 805, thereby driving the linkage frame 8 to move relative to the second rotating cylinder 803, and ensuring that the initial distance between the linkage frame 8 and the second rotating cylinder 803 and the spacing between the connecting column 7 and the first rotating cylinder 703 are equal, so that the radius of the circular motion of the linkage frame 8 and the connecting column 7 is equal, ensuring smooth testing work, so that the amplitude of the shaking of the shaking plate can be adjusted through the above operation, and the shaking speed of the shaking plate can be adjusted by adjusting the output speed of the rotating motor 33, so that the intensity of the anti-shaking test can be adjusted to meet different needs;

[0070] When the rotating arm 30 rotates, it will drive the connecting frame 27 and the counterweight plate 28 to perform circular motion. The two counterweight plates 28 obtain centrifugal force moving away from each other while performing circular motion, and press the pressure plate 25 downward through the inclined rod 26. The pressure plate 25 presses the second arc seat 23 downward through the second annular track 24, and presses through the second pressure sensor 21. When the second pressure sensor 21 senses that the pressure value changes slightly, it means that the rotating arm 30 is moving at a uniform speed and the test is proceeding normally. When the pressure value sensed by the second pressure sensor 21 changes dramatically or disappears, there may be slippage between the suction cup 901 and the cold storage, affecting the test results. It is necessary to re-debug and test again to avoid the problem of inaccurate test results.
