[0035] The lifting drive member 1 drives the sleeve 3 to be sleeved on the plug body 10, and the adsorption head 4 is inserted into the inner hole of the plug body 10; the sleeve 3 adsorbs the gas in the plug body 10, and the rotating drive member 2 drives the sleeve 3 to rotate, so that the steel ball 20 in the groove 31 is installed in the side hole of the plug body 10.

[0036] Specifically, the lifting drive 1 drives the sleeve 3 to move toward the plug body 10 until the plug body 10 is inserted into the groove 31 of the sleeve 3, and the plug body 10 drives the adsorption head 4 to move upward, and the adsorption head 4 is inserted into the inner hole of the plug body 10; the external vacuum device absorbs the gas inside the plug body 10 through the adsorption head 4, and the rotating drive 2 drives the plug body 10 to rotate through the sleeve 3, and the steel ball 20 in the groove 31 will be automatically installed in the side hole of the plug body 10 due to the centrifugal force and the adsorption force, thereby ensuring the stability of the steel ball 20 installed in the side hole of the plug body 10; and the steel ball assembly mechanism has a simple structure, low manufacturing cost, high assembly efficiency, and small space occupation.

[0037] In one embodiment, if Figure 1As shown, the steel ball assembly mechanism further includes a support frame 5, a material dividing member 6, a material dividing driving assembly 7, and a funnel 8 for storing steel balls 20. The funnel 8, the material dividing member 6, and the lifting driving member 1 are all mounted on the support frame 5;

[0038] The dividing piece 6 is provided with a sliding hole (not shown in the figure) and a first through hole 61 and a second through hole 62 both connected to the sliding hole, the first through hole 61 is connected to the funnel 8 at one end away from the sliding hole, and the second through hole 62 is connected to the groove 31 at one end away from the sliding hole; it can be understood that the first through hole 61 and the second through hole 62 are respectively located at the upper and lower ends of the sliding hole, and the center lines of the first through hole 61 and the second through hole 62 coincide; the first through hole 61 and the second through hole 62 are both arranged on the dividing piece 6 in the vertical direction, and the sliding hole is arranged on the dividing piece 6 in the horizontal direction.

It can be understood that the material distribution drive assembly 7 controls the connection and disconnection between the first through hole 61 and the second through hole 62 by controlling the connection and disconnection of the slide hole.

[0040] Specifically, the steel balls 20 in the funnel 8 automatically fall into the first through hole 61. When the material distribution drive assembly 7 controls the slide hole to be in the conducting state, the steel balls 20 in the first through hole 61 fall into the groove 31 through the slide hole in sequence. When the material distribution drive assembly 7 blocks the first slide hole, the steel balls 20 in the first through hole 61 will not fall into the second through hole 62 through the slide hole. In this embodiment, the design of the material distribution drive assembly 7 can control the number of steel balls 20 in the funnel 8 falling into the groove 31, that is, the steel ball assembly mechanism can control the number of steel balls 20 in the groove 31, thereby ensuring the stability of the steel balls 20 in the groove 31 installed in the side hole of the plug body 10.

[0041] In one embodiment, if Figure 1 As shown, the material distribution drive assembly 7 includes a slider with a third through hole and a mobile driving member 71 connected to the slider, and the mobile driving member 71 is used to drive the slider to slide in the slide hole so that the opposite ends of the third through hole are connected to the first through hole 61 and the second through hole 62 respectively, or so that the slider blocks the first through hole 61 and the second through hole 62.

[0042] Specifically, the steel ball 20 in the funnel 8 automatically falls into the first through hole 61. When the moving driving member 71 drives the slider to move in the sliding hole until the first through hole 61 is connected to the second through hole 62 through the third through hole, the steel ball 20 in the first through hole 61 sequentially passes through the third through hole and the second through hole 62 and falls into the groove 31. When the moving driving member 71 drives the slider to block the connection between the first through hole 61 and the second through hole 62, the steel ball 20 in the first through hole 61 will not fall into the second through hole 62. In this embodiment, the steel ball assembly mechanism has a simple structure, low manufacturing cost, and small space occupation.

[0045] Before the lifting drive member 1 drives the socket 3 to be sleeved on the plug body 10, the elastic member drives the blocking portion 41 to be inserted into the outlet of the groove 31 to block the outlet of the groove 31; it can be understood that the resilience of the elastic member drives the adsorption head 4 to move downward so that the blocking portion 41 blocks the outlet of the groove 31, so that the steel ball 20 in the groove 31 will not fall out.
