[0034] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in combination with the drawings and the descriptions of the embodiments or the prior art. It should be noted that the descriptions of these embodiments are used to help understand the present invention, but do not constitute a limitation of the present invention.

[0035] like Figure 1 As shown, the existing high-voltage connection unit includes a housing 1 and a bushing 2, a sealing ring 3 and a shielding member 4 which are all installed on the housing 1; the bushing 2, the sealing ring 3 and the shielding member 4 are arranged according to Figure 1 The bushing 2 is inserted into the housing 1 in the direction shown, and the bushing 2 and the housing 1 are interference fit. Figure 2 As shown, the high-voltage connection unit assembly and testing equipment for assembling the high-voltage connection unit of this embodiment includes a table 5 and a turntable A6 and a turntable B7 installed at intervals on the table 5; the turntable A6 and the turntable B7 are both rotatably arranged, and the rotation axis of the turntable A6 is parallel to the rotation axis of the turntable B7; the turntable A6 and the turntable B7 can be rotated by existing technologies such as cam dividers and servo motors; a plurality of product fixing units A8 are installed on the turntable A6; the plurality of product fixing units A8 are evenly distributed along the rotation direction of the turntable A6, and a shell feeding unit 9, a shielding component installation unit 10, a bushing feeding unit 11 and a bushing pressing unit 12 are sequentially arranged along the rotation direction of the turntable A6; the product fixing unit A8 is used to position the shell 1, as shown in FIG. Figure 3As shown, the product fixing unit A8 has a first supporting surface 13 perpendicular to the rotation axis of the turntable A6 and an elastic telescopic pin 14 inserted in the first supporting surface 13; the number of the elastic telescopic pins 14 is the same as the number of the bushings 2 of the assembled high-voltage connection unit; the elastic telescopic pin 14 has a first cylindrical section 15 adapted to the hole for installing the bushing 2 on the shell 1 and a second cylindrical section 16 adapted to the hole of the bushing 2; the second cylindrical section 16 is located above the first cylindrical section 15; a plurality of product fixing units B17 are installed on the turntable B7; the plurality of product fixing units B17 are evenly distributed along the rotation direction of the turntable B7, and a sealing ring assembly unit 18 and a discharging robot 19 for transferring the assembled high-voltage connection unit to the outside of the turntable B7 are sequentially arranged along the rotation direction of the turntable B7; a transfer unit 20 for picking up the product in the product fixing unit A8 and turning it 180° and then installing it in the product fixing unit B17 is arranged between the turntable A6 and the turntable B7. The turntable A6 rotates step by step at a given angle, so that each product fixing unit A8 on the turntable A6 passes through the shell loading unit 9, the shielding component installation unit 10, the bushing loading unit 11 and the bushing pressing unit 12 in sequence; the shell loading unit 9 is used to install the shell 1 to each product fixing unit A8 one by one, and the first cylindrical section 15 of the product fixing unit A8 is inserted into the hole of the shell 1 for installing the bushing 2 to position the shell 1; the shielding component installation unit 10 is used to install the shielding component 4 one by one into the shell 1 of each product fixing unit A8; the bushing loading unit 11 is used to install the bushing 2 one by one into the The second cylindrical section 16 is used to pre-position the bushing 2. Since the first cylindrical section 15 and the second cylindrical section 16 are located on the same part, the coaxiality is easier to ensure, ensuring that the bushing 2 is accurately aligned with the hole in the shell 1 for installing the bushing 2. The bushing pressing unit 12 is used to press the bushing 2 of the second cylindrical section 16 into the shell 1. When the bushing pressing unit 12 presses the bushing 2, the elastic telescopic pin 14 is gradually retracted under the force, and the bushing 2 gradually enters the hole in the shell 1 for installing the bushing 2 under the guidance of the elastic telescopic pin 14. After the bushing 2 is pressed, the elastic telescopic pin 14 extends out to position the shell 1 through the second cylindrical section 16. The transfer unit 20 takes out the shell 1 on which the bushing 2 and the shielding part 4 have been installed from the product fixing unit A8, and then turns it over 180° so that the surface of the shell 1 with the sealing ring 3 installed faces upward, and then puts the shell 1 into the product fixing unit B17 on the turntable B7. The structure of the product fixing unit B17 can be the same as that of the product fixing unit A8, or a similar structure can be adopted, such as fixing at least two pins on a plate, and the two pins are used to cooperate with the bushing 2 for positioning.The turntable B7 rotates step by step at a given angle, so that each product fixing unit B17 on the turntable B7 passes through the sealing ring assembly unit 18 and the discharging robot 19 in turn. The sealing ring assembly unit 18 is used to install the sealing ring 3 into the shell 1, and the existing structure can be adopted; the discharging robot 19 is used to move the assembled high-voltage connection unit out of the turntable B7, thereby completing the assembly of the high-voltage connection unit.

[0036] In some embodiments, Figure 3 As shown, the second cylindrical section 16 may include a positioning section 21 and a guide section 22. The diameter of the positioning section 21 is adapted to the diameter of the bushing 2 hole, and the diameter of the guide section 22 gradually decreases from bottom to top. Since the diameter of the guide section 22 gradually decreases from bottom to top, the bushing 2 hole diameter is larger than the top diameter of the guide section 22, making it easier for the bushing 2 to be inserted into the second cylindrical section 16. At the same time, under the guidance of the guide section 22, the bushing 2 smoothly transitions to the positioning section 21, thereby positioning the bushing 2. In some embodiments, as Figure 3 As shown, the length of the second cylindrical section 16 is not less than the length of the bushing 2, so that the bushing 2 is not easy to fall out of the second cylindrical section 16 during the rotation of the turntable A6. In order to conveniently display the specific structure of the elastic retractable pin 14, the product fixing unit A8 is cut by two planes passing through the center of a certain elastic retractable pin 14 and perpendicular to each other, as shown in FIG. Figure 3 As shown, the product fixing unit A8 may include a base plate 23, a stepped pin 24, a compression spring A25 and a spring seat 26. The base plate 23 is fixed to the turntable A6. The top surface of the base plate 23 is the first supporting surface 13. The spring seat 26 is fixed below the base plate 23. The compression spring A25 is installed in the spring seat 26. The two ends of the compression spring A25 respectively abut against the stepped pin 24 and the spring seat 26. The stepped pin 24 includes, from bottom to top, a limit stage 27 located below the base plate 23, a first section 28 that slidably cooperates with the base plate 23, a second section that matches the hole for installing the bushing 2 on the housing 1, and a third section that matches the hole of the bushing 2. The second section is the first cylindrical section 15, and the third section is the second cylindrical section 16. The joint surface of the first section 28 and the second section is not higher than the first supporting surface 13 or the diameter of the first section 28 is equal to the diameter of the second section, so that the housing 1 can be supported by the first supporting surface 13. The stepped pin 24 is the elastic telescopic pin 14.

In some embodiments, as Figure 5As shown, the shielding component installation unit 10 may include a loader 32, a shielding component fixing unit 33, a visual inspection device B34 arranged between the loader 32 and the shielding component fixing unit 33 and used to detect the weld of the shielding component 4, a robot C35 used to place the shielding component 4 at the outlet of the loader 32 into the fixing unit, a visual inspection device C37 arranged above the shielding component fixing unit 33 and used to detect the elastic height of the shielding component 4, and a robot D36 used to place the shielding component 4 of the shielding component fixing unit 33 into the product fixing unit A8, the visual inspection device B34 is used to detect the weld of the shielding component 4 during the process of placing the shielding component 4 from the loader 32 into the shielding component fixing unit 33; the loader 32, the robot C35, the robot D36, the visual inspection device B34 and the visual inspection device C37 are all installed on the table 5; the visual inspection device A30, the visual inspection device B34 and the visual inspection device C37 can all be implemented using CCD cameras, lenses and light sources in the prior art, and the specific structure is the prior art and will not be repeated here. By setting up visual inspection device A30, visual inspection device B34 and visual inspection device C37, unqualified shells 1 and shielding parts 4 are removed in advance, so that when analyzing the poor assembly of the high-voltage connection unit, the bad shell 1 is excluded, saving analysis time. Manipulator A31, manipulator C35 and manipulator D36 can all be implemented by existing multi-axis manipulators with electric grippers or pneumatic grippers. The specific structure is the existing technology and will not be repeated here. In some embodiments, such as Figure 5 As shown, the shielding component fixing unit 33 can be connected to a single-axis robot arm B38, and the single-axis robot arm B38 is used to drive the shielding component fixing unit 33 to move between the discharge position, the picking position and the detection position.

After the shielding member 4 is placed, the telescopic plate 40 is extended, and the two slots 41 are closed to position and clamp the shielding member 4, so as to avoid the shielding member 4 shaking and causing misjudgment during the detection of the shielding member 4 by the visual detection device B34 and the visual detection device C37.

Figure 8 As shown, the tray separation mechanism 58 includes a tray lifting part 59, a pressure plate part 60, a telescopic cylinder A61 for driving the tray lifting part 59 to extend and retract horizontally along the conveying direction of the vertical conveyor 57, and a telescopic cylinder B62 for driving the tray lifting part 59 to rise and fall. The pressure plate part 60 has a telescopic part 63 for extending and retracting horizontally along the conveying direction of the vertical conveyor 57, and the telescopic part 63 is connected to the tray lifting part 59 through a lifting and sliding structure.

The multiple bushings 2 are arranged in a row at equal intervals by the offset mechanism 70, and then the multiple bushings 2 at the offset mechanism 70 are clamped at one time by the multiple clamping claws B72. Finally, the multiple bushings 2 are placed one by one in the product fixing unit A8 by the mechanical arm B73 in cooperation with the telescopic clamping claws B72. Compared with the stroke of the mechanical arm B73, the telescopic stroke of the clamping claws B72 and the stroke of the offset mechanism 70 are shorter. Therefore, when installing multiple bushings 2 of the same high-voltage connection unit, the mechanical arm only needs to go back and forth once, which is more efficient. In this embodiment, Fig. 9 As shown, the extension and retraction of the clamping jaw B72 is achieved by a telescopic cylinder installed at the output end of the robot arm B73.

The first positioning groove 76 is first directly opposite to the outlet of the vibrating feeder B69, and the bushing 2 enters the positioning groove 76 through the outlet of the vibrating feeder B69, and then the single-axis mechanical arm A75 drives the dislocation plate 74 to move a set distance, that is, the distance between two adjacent bushings 2, and the bushing 2 at the outlet of the vibrating feeder B69 enters the next positioning groove 76, and the single-axis mechanical arm A75 drives the dislocation plate 74 to move a set distance, and so on, to complete the dislocation of the bushings 2 equal to the number of positioning grooves 76, and the number N of positioning grooves 76 is the same as the number of bushings 2 on the high-voltage connection unit. In order to prevent the bushing 2 in the positioning groove 76 from falling off, a baffle 77 can be fixed on the outlet side of the vibrating feeder B69. The baffle 77 extends along the moving direction of the offset plate 74 to seal the openings of at least N-1 positioning grooves 76.

Initially, the two sliders A98 are in a closed state, the four opening posts 104 are closed, and the sealing ring 3 in a free state is sleeved outside the four opening posts 104. The cam mechanism 100 drives the two sliders A98 to separate, and the four sliders B99 move along the track groove 103, thereby opening the sealing ring 3.

[0044] In some embodiments, Figure 2 As shown, the high-voltage connection unit assembly and testing device may further include an interchangeability testing unit 114 disposed between the sealing ring assembly unit 18 and the discharging robot 19. Fig.15As shown, the interchangeability test unit 114 may include a mating end fixing seat 115 located below the product fixing unit B17 and arranged to be lifted, an unlocking rod A116 which is telescopically arranged for unlocking the primary buckle 123, an unlocking rod B117 which is telescopically arranged for unlocking the secondary buckle 124, a clamping jaw H118 arranged above the product fixing unit B17, a telescopic cylinder E119 which drives the clamping jaw H118 to be lifted, and a pressure sensor B120 which is arranged between the output end of the telescopic cylinder E119 and the clamping jaw H118. The mating end fixing seat 115 is provided with an avoidance hole A121 for avoiding the unlocking rod A116, and the product fixing unit B17 is provided with an avoidance hole B (not shown in the figure) for avoiding the unlocking rod B117. Figure 1 As shown, the shell 1 has a primary buckle 123 and a secondary buckle 124, and the mating connection unit that matches the high-voltage connection unit is placed in the mating end fixing seat 115 and fixed. During the test, the clamp H118 descends and clamps the high-voltage connection unit on the product fixing unit B17, and then the mating end fixing seat 115 rises, and the mating connection unit is gradually inserted into the high-voltage connection unit, and the pressure sensor B120 detects the insertion force during the insertion process; then, the unlocking rod A116 and the unlocking rod B117 extend to release the primary buckle 123 and the secondary buckle 124 that lock the mating connection unit, and the clamp H118 rises to lift the high-voltage connection unit upward, and the pressure sensor B120 detects the pull-out force during the pull-out process of the high-voltage connection unit. After the high-voltage connection unit is completely pulled out, the mating end fixing seat 115 descends with the mating connection unit, and at the same time, the clamp H118 descends to place the high-voltage connection unit into the product fixing unit B17 to complete the test. The telescopic cylinder E119 can be implemented by a servo electric cylinder. The cylinder body of the telescopic cylinder C47 is fixed to the table 5 through a bracket. The piston rod of the telescopic cylinder E119 is connected to the pressure sensor B120, and the clamping claw H118 is fixed to the pressure sensor B120.

[0045] In some embodiments, Figure 2 As shown, the high-voltage connection unit assembly and detection device may further include an airtightness detection unit 122 for detecting the airtightness of the high-voltage connection unit, such as Fig.16As shown, the airtightness detection unit 122 may include two single-axis mechanical arms E125 each having a material receiving position, an airtightness detection position and a material discharging position and arranged in parallel, a cover plate 126 arranged at the airtightness detection position and arranged to be lifted and lowered, and two product fixing units C127 respectively arranged at the output ends of the two single-axis mechanical arms E125, the cover plate 126 is located above the two product fixing units C127, and at least one of the two product fixing units C127 is telescopically arranged in a direction perpendicular to the single-axis mechanical arm E125; the product fixing unit C127 includes an insertion block 128 inserted into the mating end of the high-voltage connection unit, a plurality of insertion blocks 128 are arranged at intervals, and each insertion block 128 is sleeved with a sealing ring 129 for sealing the mating end of the high-voltage connection unit, and the single-axis mechanical arm E125 is installed on the table 5. Since the airtightness test time is relatively long, the airtightness test is moved outside the turntable B7, and multiple high-voltage connection units are tested at one time to match the assembly beat of the high-voltage connection unit and improve the line balance rate. The discharging robot 19 inserts the assembled high-voltage connection units one by one into the outside of the insertion block 128, and seals the mating ends of the high-voltage connection units through the sealing ring 129. Then the single-axis robot E125 moves the multiple high-voltage connection units to the bottom of the cover plate 126, and the cover plate 126 descends to seal the other end of the high-voltage connection unit, and then the air tightness test can be started. After the test is completed, the single-axis robot E125 moves the tested high-voltage connection unit to the discharging position for the next step. The cover plate 126 can seal the sealing surface of the high-voltage connection unit by means of sealing strips, etc., and an air channel is opened in the cover plate 126. The air channel has air holes corresponding to the position of the internal cavity 110 of the high-voltage connection unit. The cover plate 126 is connected to the air tightness tester (not shown in the figure) and the air channel inside the cover plate 126 through an air pipe and a joint, thereby connecting the air tightness tester and the internal cavity 110 of the high-voltage connection unit. By setting two single-axis robotic arms E125 and making at least one product fixing unit C127 telescopic, when the high-voltage connection unit on one product fixing unit C127 is being tested, the other product fixing unit C127 can be moved to the discharging robotic arm 19 to receive the next batch of high-voltage connection units to be tested, thereby reducing waiting time and improving efficiency. Fig.16 As shown, the single-axis robot arm E125 can be set parallel to the center line of the turntable A6 and the turntable B7. The discharging robot 19 only needs to move along the same U-shaped trajectory with the high-voltage connection unit, and the other direction is achieved by the movement of the single-axis robot arm E125 itself to reduce the stroke of the discharging robot 19. At the same time, the single-axis robot arm E125 and the discharging robot 19 can move at the same time, which is more efficient.

[0046] In some embodiments, Figure 2 and Fig.17As shown, the high-voltage connection unit assembly and testing equipment may also include a packaging machine 130, an intermediate transfer seat 131, and a manipulator F132 for transferring the high-voltage connection unit between the discharge position of the single-axis robot arm E125, the intermediate transfer seat 131, and the packaging machine 130. The intermediate transfer seat 131 has a plurality of contoured grooves 133 arranged at intervals and adapted to the high-voltage connection unit. The packaging machine 130, the intermediate transfer seat 131, and the manipulator F132 are installed on the table 5. By setting up the packaging machine 130, the high-voltage connection units that have passed the test can be automatically loaded into the tray. The packaging machine 130 can adopt the existing technology. As Fig.17 As shown, the packaging machine 130 can be implemented with the same structure as the above-mentioned feeder 32. The conveyor 57 of the packaging machine 130 is arranged at the center line of the vertical turntable A6 and the turntable B7, thereby shortening the stroke of the manipulator F132, improving efficiency and saving costs. When the high-voltage connection unit taken out from the discharge position of the single-axis robot arm E125 by the manipulator F132 is unqualified, the manipulator F132 first discards the unqualified high-voltage connection unit, and then temporarily places the qualified high-voltage connection unit on the intermediate transfer seat 131. By analogy, after all the contoured grooves 133 of the intermediate transfer seat 131 are filled with qualified high-voltage connection units, the manipulator F132 takes out the high-voltage connection unit on the intermediate transfer seat 131 and puts it into the tray of the packaging machine 130, thereby avoiding the situation where the high-voltage connection unit is missing in the grid of the tray. A plurality of telescopic clamps are installed at the end of the manipulator F132, so that multiple high-voltage connection units can be taken and placed in one movement of the manipulator F132.

Fig.18As shown, the elastic telescopic rod 136 is in the shape of a step with a thick middle and thin ends. The step of the elastic telescopic rod 136 is located between two fixing plates B139. A compression spring E140 is arranged between the step of the elastic telescopic rod 136 and the fixing plate B139 located above. The fixing plate B139 located below is used to limit the elastic telescopic rod 136. The upper end of the elastic telescopic rod 136 extends out of the fixing plate B139 located above. The elastic telescopic rod 136 extending out of the fixing plate B139 above is provided with the above-mentioned small hole 138. The through-beam photoelectric sensor 137 is installed on the fixing plate B139 located above.
