It is easy for those skilled in the art to understand that the order of steps or operations of the methods related to the embodiments provided herein can also be changed. Any order in the drawings and embodiments is only for illustration of use and does not imply that a certain order is required, unless it is explicitly stated that a certain order is required.

[0039] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) under reasonable circumstances (not self-contradictory).

[0040] As shown in Figure 1 The high-voltage connection unit production system of the embodiment includes a circular conveying line 1, an elongated circular conveying line 2, and a first mechanical hand 3 for moving the shielding member from the circular conveying line 1 to the elongated circular conveying line 2; a shell assembling machine 4, a sealing ring assembling machine 5, a protective cover assembling machine 6, a lock catch assembling machine 7, a plug-in testing machine 8, and a leakage detection machine 9 are arranged in sequence along the conveying direction of the elongated circular conveying line 2; a base assembling machine 10, a shielding cover assembling machine 11, and a terminal insertion machine 12 are arranged in sequence along the conveying direction of the circular conveying line 1; the shielding cover assembling machine 11 includes a shielding cover feeding machine 13, a shielding cover closing device 14, a second mechanical hand 15 for reciprocating between the shielding cover feeding machine 13 and the shielding cover closing device 14, and a third mechanical hand 16 for loading the shielding cover closed in the shielding cover closing device 14 into the circular conveying line 1.

[0041] In the embodiment, the circular conveying line 1 can be a direct-drive motor turntable structure, and a plurality of first carriers for positioning the shielding cover are installed on the turntable. The elongated circular conveying line 2 can be an annular guide rail conveying line, and a plurality of second carriers for positioning the shell are installed on the annular guide rail conveying line. The shell assembling machine 4, the sealing ring assembling machine 5, the protective cover assembling machine 6, the lock catch assembling machine 7, the base assembling machine 10, the shielding cover assembling machine 11, and the terminal insertion machine 12 can all use a feeder and a mechanical hand structure, that is, the mechanical hand takes out the corresponding parts from the feeder, and then loads them into the shielding member or the shell on the circular conveying line 1 or the elongated circular conveying line 2. The plug-in testing machine 8, the leakage detection machine 9, and the interchangeability testing unit and the air tightness detection unit in the Chinese invention patent with the publication number CN119681638A and the name High-voltage connection unit assembling and detecting equipment.

[0042] The two halves of the split shielding cover are completely identical, and are loaded by the tray, so the shielding cover loading machine 13 can use the existing tray loading machine to load the shielding cover. The U-shaped shielding cover opening is placed downward in the tray, and at least one of the shielding covers needs to be flipped to close the shielding cover. How to flip and where to flip are technical problems to be solved by those skilled in the art. In the embodiment, as shown in Figure 2 The third robot 16 includes a body 17 and a picking tool 18 mounted on the body 17, as shown in Figure 3 The picking tool 18 includes a mounting seat 19 arranged in a lifting manner, a vacuum suction head 20 hingedly connected to the lower end of the mounting seat 19, and a telescopic cylinder 21 hingedly connected to the mounting seat 19 and the vacuum suction head 20 at both ends, the telescopic cylinder 21 is used to drive the vacuum suction head 20 to rotate at least 90°. Initially, the vacuum suction head 20 faces downward to suck the shielding cover, and then in the process of moving the shielding cover to the shielding cover closing device 14 by the third robot 16, the telescopic cylinder 21 acts to rotate the vacuum suction head 20 by 90°, that is, the vacuum suction head 20 is in a horizontal state. Since the shielding cover is flipped in the process of moving the shielding cover to the shielding cover closing device 14, it has no effect on the production rhythm. Further, the picking tool 18 can be provided with two, so as to simultaneously suck and flip two shielding covers, thereby improving the efficiency.

[0043] In the embodiment, as shown in Figure 4 and Figure 5 The shielding cover closing device 14 can include two positioning seats 22 opening and closing on the same track and a stopper 23 arranged between the two positioning seats 22. The stopper 23 is arranged in a telescopic manner along the vertical direction of the track. The positioning seat 22 has a supporting surface 24 and a suction surface 25 perpendicular to the supporting surface 24. The suction surface 25 is provided with a suction hole 26 connected to a vacuum generator. The two sides of the supporting surface 24 are provided with clamping blocks 27, which are arranged in an opening and closing manner. The opening and closing directions of the two clamping blocks 27 are consistent with the telescopic direction of the stopper 23. The two clamping blocks 27, the supporting surface 24, the suction surface 25 and the stopper 23 form a positioning space in the shape of a cube with an open top, which is used for positioning the shielding cover. The third robot 16 places the flipped shielding cover into the positioning space, and the two clamping blocks 27 are closed to position the shielding cover. At the same time, the suction surface 25 sucks the shielding cover by vacuum action, and then the stopper 23 is retracted, and the two positioning seats 22 are closed to close the two shielding covers. Since the two positioning seats 22 open and close on the same track, the concentricity of the two positioning seats 22 is ensured, so that the two shielding covers are accurately aligned. The telescopic stopper 23 can avoid the shielding cover from falling when it is just placed. The suction surface 25 sucks the shielding cover during the entire closing process to avoid the shielding cover from falling during the closing process.

[0044] In the embodiment, as shown in Figure 4As shown, each positioning seat 22 can be fixed with an electric clamp jaw 28, and two fingers of the electric clamp jaw 28 are connected with two clamping blocks 27 respectively.

Correspondingly, the first carrier seat for adapting to the shielding covers of high-voltage connection units of different specifications can be installed on the circular conveying line 1, and the second carrier seat for adapting to the shielding covers of high-voltage connection units of different specifications can be installed on the long circular conveying line 2.

The plurality of first vibration discs 32 are respectively used for the vibration feeding of the bases of high-voltage connection units of different specifications; the base enters the first guide groove 34 from the outlet of the first vibration disc 32, and due to the action of the first belt conveying line 33, the base moves along the first guide groove 34; the widths of the plurality of first guide grooves 34 are respectively matched with the widths of the bases of high-voltage connection units of different specifications, so as to realize the feeding of the bases of high-voltage connection units of different specifications. At the same time, arranging the plurality of first vibration discs 32 at one place is convenient for the operator to supplement the bases into the first vibration discs 32.

[0046] In the embodiment, as shown in Figure 1 The shell assembly machine 4 can include a shell feeder 35 and a fifth mechanical arm 36 reciprocating between the shell feeder 35 and the long circular conveying line 2; the shell feeder 35 includes a second guide 37, a plurality of second vibration discs 38 arranged in sequence along the direction perpendicular to the center line of the circular conveying line 1 and the long circular conveying line 2, and a second belt conveying line 39 extending along the direction perpendicular to the center line of the circular conveying line 1 and the long circular conveying line 2; as shown in Figure 7As shown, the second guide 37 has a plurality of second guide grooves 40 arranged along the direction of the line connecting the centers of the circular conveying line 1 and the long circular conveying line 2, and the second guide grooves 40 extend along the direction perpendicular to the line connecting the centers of the circular conveying line 1 and the long circular conveying line 2; the number of the second guide grooves 40 is equal to the number of the second vibration discs 38; the two ends of the second guide grooves 40 are respectively the second feeding end and the second discharging end; the outlets of the plurality of second vibration discs 38 are respectively and correspondingly connected to the second feeding ends of the plurality of second guide grooves 40; the fifth mechanical arm 36 is used to take out the shell from the second discharging end and load the shell into the long circular conveying line 2. The plurality of second vibration discs 38 are respectively used for the vibration feeding of the shells of different specifications of high-voltage connecting units; the shells enter the second guide grooves 40 from the outlets of the second vibration discs 38, and move along the second guide grooves 40 due to the action of the second belt conveying line 39; the widths of the plurality of second guide grooves 40 are respectively matched with the widths of the shells of the plurality of different specifications of high-voltage connecting units, so as to realize the feeding of the shells of the plurality of different specifications of high-voltage connecting units. At the same time, the plurality of second vibration discs 38 are arranged at one place, which is convenient for the operator to supplement the shells into the second vibration discs 38. Further, the shell feeding machine 35 and the base feeding machine 29 are located on the same side of the line connecting the centers of the circular conveying line 1 and the long circular conveying line 2; and the shell feeding machine 35 and the base feeding machine 29 have a maintenance channel. The first vibration disc 32 and the second vibration disc 38 are arranged at one place, so as to reduce the walking distance of the personnel when supplementing the materials. The maintenance channel is convenient for the personnel to supplement the materials and also convenient for the maintenance personnel to perform the maintenance work.

[0047] In the present embodiment, as Figure 8As shown, the terminal inserting machine 12 comprises a horizontal moving mechanical arm 41, a lifting mechanical arm 42 fixed to the output end of the horizontal moving mechanical arm 41, and a terminal gripper 43 and a terminal pressing head 44 both fixed to the output end of the lifting mechanical arm 42; the terminal pressing head 44 comprises a pressing head body 45 sliding vertically, and a pressure sensor 46 connected to the output end of the lifting mechanical arm 42 and the pressing head body 45 respectively; the terminal gripper 43 picks up the terminal, the horizontal moving mechanical arm 41 and the lifting mechanical arm 42 cooperatively drive the terminal gripper 43 to insert the picked-up terminal into a part of the base, then the horizontal moving mechanical arm 41 moves to make the terminal pressing head 44 face the terminal inserted into the base, and the lifting mechanical arm 42 drives the terminal pressing head 44 to move downward to gradually press the terminal into the base and to the right position. On the one hand, the length of the terminal itself has a tolerance, and on the other hand, the terminal gripper 43 cannot just contact the shoulder of the terminal when clamping the terminal. If the terminal is directly inserted into the base by the terminal gripper 43 to the right position, on the one hand, it is impossible to determine whether the terminal is actually in the right position; on the other hand, if the friction between the terminal and the gripper is less than the friction between the terminal and the base, i.e. the insertion force, the terminal gripper 43 and the terminal will produce sliding friction, which will cause damage to the plating layer of the terminal. Therefore, only the guide part of the terminal is inserted into the base by the terminal gripper 43, and then the terminal is inserted into the right position by the terminal pressing head 44; the pressure sensor 46 is used to monitor the pressing force during the pressing of the terminal, which can detect the abnormal insertion of the terminal on the one hand, and when the terminal is inserted into the right position, the pressing force will change sharply, which can be used as a signal that the terminal is pressed into the right position, overcoming the difficulty of not knowing how to know whether the terminal is actually in the right position. In this embodiment, as shown in Figure 9 As shown, the terminal inserting machine 12 can further comprise a terminal cutting device 47, which can comprise a third guide 49 with a third guide groove 48, a cutting device 50 for cutting the terminal tape in the guide groove, and a feeding device 51 for driving the terminal tape to move intermittently along the guide groove at a set step distance; the top of the third guide groove 48 is open to make the terminal extend out of the third guide groove. Since the top of the third guide groove 48 is open, the terminal can extend upward out of the third guide groove 48; the terminal extending out of the third guide groove 48 can be clamped by the terminal gripper 43 and then fed into the base in the circular conveying line 1, realizing online cutting and saving the intermediate terminal handling process.

The protruding portion can be a roller such as a bearing, so as to reduce the abrasion. Since the lock catch is assembled into the shell from the lower portion, compared with the assembly from the upper portion, the space is more limited, therefore, through the ingenious arrangement of the lifting fixed jaw 73, the reset spring 77 and the wedge 75, and through the vertical displacement in the lock catch assembly process, the wedge 75 acts on the protruding portion 80 of the movable jaw 76, the movable jaw 76 is radially expanded in the pre-assembly of the lock catch, so that the lock catch pre-assembly and the jaw opening double processes are integrated into a single movement stroke, and then the lock catch is completely pushed into the shell through the push rod 78; at the same time, after the lock catch assembly is completed, the fixed jaw 73 is lowered, the protruding portion 80 is separated from the inclined surface of the wedge 75, and the fixed jaw 73 can also be used for clamping the lock catch 82. Figure 13 As shown, when the tenth robot 70 is in the material taking mode, the side surface opposite to the movable jaw 76 and the fixed jaw 73, and the top surface of the push rod 78 jointly form a positioning space for positioning the lock catch 82, the positioning space is in abutment with the material slot, and the lock catch enters the positioning space; the positioning space and the lock catch 82 can be in clearance fit, so as to smoothly enter the positioning space, in order to avoid the lock catch 82 from falling, a second stop block 81 can be arranged at the end of the fixed jaw 73 away from the lock catch feeding flow channel 68, the tenth robot is a single shaft robot arm, and the lock catch is driven to move in the direction perpendicular to the side surface opposite to the movable jaw 76 and the fixed jaw 73. Another optional mode can be that the upper and lower ends of the wedge are provided with inclined surfaces, that is, the movable jaw is also in the open state at the bottom, so as to facilitate the lock catch to smoothly enter the positioning space, and then the first lifting cylinder 74 drives the fixed jaw to move upward by a small distance to separate from the bottom inclined surface, so that the fixed jaw clamps the lock catch 82; another optional mode can also be that a misalignment mechanism is arranged at the outlet of the lock catch feeding flow channel 68, and the lock catch is directly pushed into the positioning space through the misalignment mechanism.
