[0040] Specifically, such as Figure 1-4 As shown, the inner side of the shock-absorbing transmission belt 2 is rotatably connected to a plurality of drive rollers, the surface of the drive rollers is wrapped with a shock-absorbing film, the ends of the drive rollers are rotatably connected to the inner side wall of the transmission outer frame 1, and the end of one of the drive rollers is fixedly connected to the output shaft of the electric motor, and the surface of the electric motor body is fixedly connected to the rear end face of the transmission outer frame 1 through a shock-absorbing pad. The arrangement component 4 includes a first outer protective shell 401, which is stacked inside the storage code box 3 or above the shock-absorbing transmission belt 2. The bottom of the inner side of the first outer protective shell 401 is clamped with an anti-slip sleeve 402, and the interior of the anti-slip sleeve 402 is embedded with a charge-coupled device 403. The arrangement component 4 also includes a built-in buffer seat 404, the top of the built-in buffer seat 404 is fixedly connected to the bottom of the first outer protective shell 401, the surface of the built-in buffer seat 404 is sleeved with an external buffer seat 405, and the bottom of the inner side of the external buffer seat 405 is fixedly connected to the bottom of the built-in buffer seat 404 through a shock-absorbing cotton body 406.

[0041] The specific implementation method is as follows: a plurality of anti-dropping ferrules 402 are mounted on the first outer protective shell 401, and the anti-dropping ferrules 402 are used to securely connect the charge-coupled device 403 to the first outer protective shell 401, thereby realizing the testing of multiple charge-coupled devices 403 at a time. When the first outer protective shell 401 is dropped from the storage code box 3 to the shock-absorbing transmission belt 2, the built-in buffer seat 404 will retract within the external buffer seat 405, supplemented by the cushioning effect of the shock-absorbing cotton body 406, so that the first outer protective shell 401 can be stably placed on the storage code box 3.

[0042] Specifically, such as Figure 4 As shown, the test assembly 5 includes a second outer protective shell 501, the bottom of the second outer protective shell 501 is fixedly connected to the top of the transmission outer frame 1 at a position corresponding to the tail end of the shock-absorbing transmission belt 2, and a test bench 503 is provided on the inner side of the second outer protective shell 501 at a position corresponding to the shock-absorbing transmission belt 2. The top of the test bench 503 is fixedly connected to the output end of the hydraulic cylinder 504 through a shock-absorbing pad, and a pass-through connection port 502 is also provided at the side end surface of the second outer protective shell 501 at a position corresponding to the shock-absorbing transmission belt 2.

[0043] The specific implementation method is as follows: when the electric motor is working, its output shaft will drive the drive roller to rotate stably, and the torque on the surface of the drive roller can drive the shock-absorbing transmission belt 2 to transmit the first outer protective shell 401. The first outer protective shell 401 sent to the rightmost side stops moving due to the obstruction of the wedge-shaped seat 802. At this time, the built-in system of the fixture controls the hydraulic cylinder 504 to extend. Under the push of the hydraulic cylinder 504, the test platform 503 moves toward the direction of the first outer protective shell 401 until the test platform 503 and the charge-coupled device 403 built in the first outer protective shell 401 achieve a stable electrical connection.

[0045] The specific implementation method is as follows: when the hydraulic cylinder 504 moves along the flow direction of the shock-absorbing transmission belt 2, it will also drive the threaded connection tube 602 to transmit on the surface of the threaded connection shaft 601. Under the combined effect of torsion and thread bite force, the threaded connection shaft 601 will rotate and drive the torsion spring 603 to deform. Therefore, after completing the test work, the threaded connection shaft 601 will rotate under the action of the reset elastic force of the torsion spring 603, and then it will be able to drive the hydraulic cylinder 504 and the test table 503 on the hydraulic cylinder 504 to perform a reset action.

[0046] Specifically, such as Figure 4 and 5As shown, the heat dissipation assembly 7 includes an external piston cylinder 701, the end of the external piston cylinder 701 is fixedly connected to the end surface inside the second outer protective shell 501, and an internal piston shaft 703 is sleeved in the external piston cylinder 701. One end of the internal piston shaft 703 is fixedly connected to the end surface inside the external piston cylinder 701 through a first support spring 702, and the other end of the internal piston shaft 703 is fixedly connected to the top of the threaded connection cylinder 602 through a right-angle bracket. A return pipe 704 is clamped at the end surface of the external piston cylinder 701, and the end of the return pipe 704 away from the external piston cylinder 701 is clamped on the side end surface of the second outer protective shell 501. At the position corresponding to the shock-absorbing transmission belt 2, the limiting assembly 8 includes a wedge-shaped seat 802, which is slidably connected to the top of the transmission outer frame 1, and a transfer roller 801 is rollingly connected to the inclined surface of the wedge-shaped seat 802. The transfer roller 801 is fixedly connected to a side close to the test bench 503.

The bottom of the sliding connection seat 804 is fixedly connected to the top of the transmission outer frame 1, and a second support spring 805 is embedded in the sliding connection groove 803 at the position corresponding to the sliding connection seat 804.

[0047] The specific implementation method is as follows: when the test bench 503 and the hydraulic cylinder 504 on the test bench 503 move along the transmission direction of the shock-absorbing transmission belt 2, the threaded connection tube 602 will push the built-in piston rod to retract in the external piston tube 701 through the right-angle frame, and then blow air toward the test bench 503 through the return pipe 704, and supplemented by the flow effect generated by the shock-absorbing transmission belt 2, a good heat dissipation effect is achieved.

[0048] Working principle: When in use, the staff will sequentially embed multiple charge coupled devices 403 on the built-in anti-dropout ferrules 402 of multiple first outer protective shells 401, and then put multiple first outer protective shells 401 into the interior of the storage code box 3 in a stacked manner, and then control the electric motor to operate. When the electric motor is working, its output shaft will drive the driving roller to rotate stably, and the torque on the surface of the driving roller will drive the shock-absorbing transmission belt 2 to transmit the first outer protective shell 401, and it will be sent to the first outer protective shell 401 on the far right. 1 stops moving forward due to the obstruction of the wedge-shaped seat 802. At this time, the built-in system of the fixture controls the hydraulic cylinder 504 to extend. Under the push of the hydraulic cylinder 504, the test platform 503 moves toward the first outer protective shell 401 until the test platform 503 and the charged coupled device 403 built in the first outer protective shell 401 achieve a stable electrical connection. During the descent process, the test platform 503 drives the transfer roller 801 to roll on the inclined surface of the wedge-shaped seat 802. Taking advantage of the special inclined surface structure of the wedge-shaped seat 802, the wedge-shaped seat 802 will move away from the first outer protective shell. The protective shell 401 moves in the direction of the protective shell 401. At this time, the first outer protective shell 401 located on the far right will drive the test bench 503 and the hydraulic cylinder 504 on the test bench 503 to move along the transmission direction of the shock-absorbing transmission belt 2 until the test work is completed. After the test work is completed, the system controls the hydraulic cylinder 504 to retract. Since the hydraulic cylinder 504 moves along the flow direction of the shock-absorbing transmission belt 2, it will also drive the threaded connection tube 602 to transmit on the surface of the threaded connection shaft 601. Under the combined effect of torque and thread bite force, the threaded connection shaft 601 will rotate and drive the torsion spring 603 to deform. Therefore, after the test work is completed, the threaded connection shaft 601 will rotate under the action of the reset elastic force of the torsion spring 603, and then it will be able to drive the hydraulic cylinder 504 and the test table 503 on the hydraulic cylinder 504 to perform a reset action, and the test fixture will be grafted onto the shock-absorbing transmission belt 2, and supplemented by the storage code box 3. This can not only improve the work efficiency of relevant staff, but also allow staff to perform other auxiliary work during the test process, which is conducive to improving corporate productivity.
