[0026] To ensure the basic requirements of component placement surface, the number of each row of U-shaped frame 5 is at least 4 parallelly arranged;To ensure that there is no gap in the middle when two rows of roller column 6 are in V-shaped distribution, the axial overlapping distance of two rows of roller column 6 is at least 30cm when they are in horizontal distribution.

[0027] Specifically, the swing seat 4 comprises an upper seat body 41 and a lower seat body 43, the upper seat body 41 is fixedly assembled with the U-shaped frame 5, the lower seat body 43 is fixedly assembled with the rotating disc 3, and the aligned upper seat body 41 and lower seat body 43 are rotatably assembled; so as to support the U-shaped frame 5, swing the U-shaped frame 5, and realize stable and reliable structure.

[0028] The lower seat body 43 is fixedly installed with a limiting block 42 for blocking the upper seat body 41 on one side close to the side wall of the box body 1; when the two rows of roller columns 6 are horizontally distributed, the lower seat body 43 and the upper seat body 41 are in a vertical state, and the upper seat body 41 abuts against the limiting block 42, so as to improve the accuracy of the horizontal distribution of the two rows of roller columns 6.

[0029] As shown in Figure 4 The lifting assembly 2 comprises push cylinders 21 and a column rod 22, two symmetrical push cylinders 21 are fixedly installed on the upper side of the rotating disc 3, the push rods of the push cylinders 21 are fixedly installed with the same column rod 22, and the column rod 22 penetrates through all the guide frames 9; the push cylinders 21 can be selected as electric cylinders, air cylinders or hydraulic cylinders according to the use requirement, and the push cylinders 21 can drive the column rod 22 to be adjusted in lifting after the push rods are extended or retracted, so as to simultaneously adjust all the guide frames 9.

[0030] In order to reduce the friction between the column rod 22 and the guide frame 9 during the lifting movement of the column rod 22, the column rod 22 is rotatably installed with a guide wheel 23, and one guide wheel 23 is arranged in each guide frame 9, so that the contact between the guide wheel 23 and the guide frame 9 is improved through the rolling of the guide wheel 23.
