The diameter of the positioning segment 21 is matched with the diameter of the hole of the bushing 2, and the diameter of the guiding segment 22 gradually decreases from bottom to top. Because the diameter of the guiding segment 22 gradually decreases from bottom to top, the diameter of the hole of the bushing 2 is greater than the diameter of the top of the guiding segment 22, so that the bushing 2 is more easily sleeved into the second cylindrical segment 16, and under the guidance of the guiding segment 22, the bushing 2 smoothly transitions to the positioning segment 21, thereby positioning the bushing 2. In some embodiments, as shown in Figure 3 The length of the second cylindrical segment 16 is not less than the length of the bushing 2, so that the bushing 2 is not easily separated from the second cylindrical segment 16 during the rotation of the rotating disc A6. In order to conveniently show the specific structure of the elastic telescopic pin 14, the product fixing unit A8 is cut by two planes perpendicular to each other and passing through the center of a certain elastic telescopic pin 14, as shown in Figure 3 The product fixing unit A8 can include a base plate 23, a stepped pin 24, a compression spring A25 and a spring seat 26.

The second segment is the first cylindrical segment 15, and the third segment is the second cylindrical segment 16. The joint surface of the first segment 28 and the second segment is not higher than the first supporting surface 13, or the diameter of the first segment 28 is equal to the diameter of the second segment, so that the shell 1 can be supported by the first supporting surface 13. The stepped pin 24 is the elastic telescopic pin 14.

The cover plate 126 can seal the sealing surface of the high-pressure connection unit through a sealing strip or the like, the cover plate 126 is provided with an air channel, the air channel is provided with an air hole corresponding to the position of the internal cavity 110 of the high-pressure connection unit, and the cover plate 126 is connected to the air channel in the cover plate 126 through a gas pipe and a joint, thereby connecting the air tightness tester (not shown in the figure) and the internal cavity 110 of the high-pressure connection unit. By arranging two single-axis mechanical arms E125 and making at least one product fixing unit C127 vertically arranged, when the high-pressure connection unit on one product fixing unit C127 is tested, the other product fixing unit C127 can be moved to the output robot 19 to receive the next batch of high-pressure connection units to be tested, thereby reducing the waiting time and improving the efficiency. For example Figure 16 As shown, the single-axis mechanical arm E125 can be arranged parallel to the center line of the turntable A6 and the turntable B7, and the output robot 19 only needs to move along the same U-shaped track with the high-pressure connection unit, and the movement in the other direction is realized by the movement of the single-axis mechanical arm E125 itself, so as to reduce the stroke of the output robot 19. At the same time, the single-axis mechanical arm E125 and the output robot 19 can act simultaneously, and the efficiency is higher.

[0047] In some embodiments, as shown in Figure 2 and Figure 17As shown, the high-voltage connection unit assembling and testing device can further comprise a packaging machine 130, a transfer carrier 131, and a robot F 132 for transferring the high-voltage connection unit between the discharge position of the single-axis robot E 125, the transfer carrier 131, and the packaging machine 130. The transfer carrier 131 has a plurality of profiled grooves 133 arranged at intervals and adapted to the high-voltage connection unit. The packaging machine 130, the transfer carrier 131, and the robot F 132 are installed on the table 5. By providing the packaging machine 130, the high-voltage connection units that pass the test can be automatically loaded into a tray. The packaging machine 130 can be of the prior art. As shown, Figure 17 The packaging machine 130 can be implemented in the same structure as the feeding machine 32 described above. The conveyor 57 of the packaging machine 130 is arranged perpendicularly to the center line of the rotary disc A 6 and the rotary disc B 7, so as to shorten the stroke of the robot F 132, improve the efficiency, and save the cost. When the high-voltage connection unit taken out of the discharge position of the single-axis robot E 125 is unqualified, the robot F 132 first discards the unqualified high-voltage connection unit, and then temporarily places the qualified high-voltage connection unit on the transfer carrier 131. In this way, all the profiled grooves 133 of the transfer carrier 131 are filled with the qualified high-voltage connection units. Then, the robot F 132 takes out the high-voltage connection units on the transfer carrier 131 and loads them into the tray of the packaging machine 130, so as to avoid the situation that the high-voltage connection units are missing in the grid of the tray. The end of the robot F 132 is provided with a plurality of clamping jaws arranged in an extendable and retractable manner, so that a plurality of high-voltage connection units can be taken and placed in one movement of the robot F 132.

[0048] In some embodiments, as shown, Figure 2 The high-voltage connection unit assembling and testing device can further comprise a shielding detection unit 134 arranged between the shielding mounting unit 10 and the bushing feeding unit 11 and used for detecting whether the shielding 4 is mounted in place. As shown, Figure 18 The shielding detection unit 134 can comprise a detection head arranged above the product fixing unit A 8 and arranged in a lifting manner. The detection head comprises a plurality of pairs of elastic retractable rods 136 arranged in pairs and distributed along the edge of the shielding 4, and a plurality of pairs of light barrier photoelectric sensors 137 arranged one-to-one corresponding to the plurality of pairs of elastic retractable rods 136. A small hole 138 for the light of the light barrier photoelectric sensor 137 to pass through is arranged at the same height of each pair of elastic retractable rods 136. The shielding detection unit 134 can be installed on the table 5 by a support. Since the elastic retractable rods 136 are arranged in pairs and symmetrically distributed along the edge of the shielding 4, if the shielding 4 is not mounted in place, the shielding 4 is in an inclined state, and the small holes 138 of at least one pair of elastic retractable rods 136 are not in a straight line. The receiver of the light barrier photoelectric sensor 137 cannot receive the light signal of the emitter of the light barrier photoelectric sensor 137, so as to determine that the shielding 4 is not mounted in place. As shown, Figure 18As shown, the elastic telescopic rod 136 is stepped with thick middle and thin ends, the step of the elastic telescopic rod 136 is located between the two fixed plates B 139, the step of the elastic telescopic rod 136 and the fixed plate B 139 located above are provided with a compression spring E 140, the fixed plate B 139 located below is used for limiting the elastic telescopic rod 136, the upper end of the elastic telescopic rod 136 extends out of the fixed plate B 139 located above, and the elastic telescopic rod 136 extending out of the fixed plate B 139 is provided with the above-mentioned small hole 138. The light barrier photoelectric sensor 137 is installed on the fixed plate B 139 located above.
