DETAILED DESCRIPTION

[0029] 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. Obviously, the following descriptions of the structures of the drawings are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0030] The following will describe the technical solutions provided by the present invention in detail by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0031] In some instances, some embodiments are not described or not described in detail because they belong to existing or conventional technologies.

[0032] In addition, the technical features described herein, or the steps of all methods or processes disclosed herein, except for mutually exclusive features and / or steps, can also be combined in any suitable manner in one or more embodiments. For those skilled in the art, it is easy 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 for illustrative purposes only and does not imply a requirement to follow a certain order unless it is explicitly stated that a certain order is required.

[0033] The serial numbers assigned to components herein, such as "first" and "second," are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" in this application, where reasonable (and not self-contradictory), include both direct and indirect connections (couplings).

[0034] like Figure 1 As shown, the high-voltage connection unit production system of this embodiment includes a circular conveyor line 1, an oblong conveyor line 2, and a first manipulator 3 for moving the shielding part from the circular conveyor line 1 to the oblong conveyor line 2; along the conveying direction of the oblong conveyor line 2, a shell assembly machine 4, a sealing ring assembly machine 5, a protective cover assembly machine 6, a lock assembly machine 7, a plug-in test machine 8 and a leakage detection machine 9 are arranged in sequence; along the conveying direction of the circular conveyor line 1, a base assembly machine 10, a shielding cover assembly machine 11 and a terminal insertion machine 12 are arranged in sequence; the shielding cover assembly machine 11 includes a shielding cover loader 13, a shielding cover closing device 14, a second manipulator 15 for reciprocating between the shielding cover loader 13 and the shielding cover closing device 14 and a third manipulator 16 for loading the shielding cover closed at the shielding cover closing device 14 into the circular conveyor line 1.

[0035] In this embodiment, the circular conveyor line 1 can be a direct-drive motor turntable structure, on which a plurality of first carriers for positioning the shielding cover are installed. The oblong conveyor line 2 can be a ring guide rail conveyor line, on which a plurality of second carriers for positioning the shell are installed. The shell assembly machine 4, the sealing ring assembly machine 5, the protective cover assembly machine 6, the lock assembly machine 7, the base assembly machine 10, the shielding cover assembly machine 11 and the terminal insertion machine 12 can all use a feeder and a manipulator structure, that is, the manipulator takes out the corresponding parts from the feeder and then loads them into the shielding parts or shells on the circular conveyor line 1 or the oblong conveyor line 2. The plug-in tester 8, the leakage detection machine 9 and the interchangeability test unit and the airtightness detection unit in the Chinese invention patent with publication number CN119681638A and the name of the high-voltage connection unit assembly and detection equipment.

[0036] The two halves of the split shielding cover have the same structure and are loaded via a tray. Therefore, the shielding cover loading machine 13 can use an existing tray loading machine to load the shielding cover. The U-shaped shielding cover is placed on the tray with the opening facing downwards. To close the shielding cover, at least one of the shielding covers must be flipped over. How to flip it over and where to flip it over are technical issues that need to be solved by those skilled in the art. In this embodiment, Figure 2 As shown, the third manipulator 16 includes a body 17 and a picking tool 18 mounted on the body 17, as shown in FIG. Figure 3 As shown, the pick-up tool 18 includes a mounting base 19 that is arranged to be raised and lowered, a vacuum head 20 hinged to the lower end of the mounting base 19, and a telescopic cylinder 21 hinged at both ends to the mounting base 19 and the vacuum head 20, respectively. The telescopic cylinder 21 is used to drive the vacuum head 20 to rotate at least 90°. Initially, the vacuum head 20 faces downward, sucking up the shield. Then, as the third manipulator 16 moves the shield to the shield closing device 14, the telescopic cylinder 21 actuates, rotating the vacuum head 20 90°, i.e., assuming a horizontal position. Since the shield is flipped during its movement to the shield closing device 14, the production cycle is not affected. Furthermore, two pick-up tools 18 can be provided to simultaneously suck up and flip two shields, improving efficiency.

[0037] In this embodiment, if Figure 4 and Figure 5 As shown, the shielding cover closing device 14 may include two positioning seats 22 located on the same track for opening and closing and a stop block 23 arranged between the two positioning seats 22. The stop block 23 is set to be telescopic along the direction perpendicular to the track. The positioning seats 22 have a support surface 24 and an adsorption surface 25 perpendicular to the support surface 24. The adsorption surface 25 has a suction hole 26 connected to the vacuum generator. Clamping blocks 27 are respectively set on both sides of the support surface 24. The two clamping blocks 27 are set to open and close. The opening and closing direction of the two clamping blocks 27 is consistent with the telescopic direction of the stop block 23. The two clamping blocks 27, the support surface 24, the adsorption surface 25 and the stop block 23 form a cubic positioning space with an open top. The positioning space is used to position the shielding cover. The third manipulator 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 adsorption surface 25 sucks the shielding cover through the vacuum effect, and then the block 23 retracts, the two positioning seats 22 are closed, and the two shielding covers are closed; 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 retractable block 23 can prevent the shielding cover from tipping over when it is just placed in; the adsorption surface 25 sucks the shielding cover during the entire closing process to prevent the shielding cover from tipping over during the closing process.

[0038] In this embodiment, if Figure 4As shown, each positioning seat 22 can fix an electric clamp 28, and the two fingers of the electric clamp 28 are respectively connected to the two clamping blocks 27. By setting the electric clamp 28, the width of the two clamping blocks 27 after closing can be controlled by parameters to adapt to the shielding covers of high-voltage connection units of various specifications, such as two-core vehicle-mounted high-voltage connectors, three-core vehicle-mounted high-voltage connectors, and four-core vehicle-mounted high-voltage connectors. Accordingly, a first carrier for the shielding covers of high-voltage connection units of different specifications can be installed on the circular conveyor line 1, and a second carrier for the shielding covers of high-voltage connection units of different specifications can be installed on the oblong conveyor line 2.

[0039] In this embodiment, if Figure 1 As shown, the base assembly machine 10 may include a base loader 29 and a fourth manipulator 30 that reciprocates between the base loader 29 and the circular conveyor line 1; the base loader 29 includes a first guide member 31, a plurality of first vibration plates 32 arranged in sequence along a direction perpendicular to the center line connecting the circular conveyor line 1 and the oblong conveyor line 2, and a first belt conveyor line 33 extending along a direction perpendicular to the center line connecting the circular conveyor line 1 and the oblong conveyor line 2; as shown Figure 6 As shown, the first guide member 31 has a plurality of first guide grooves 34 arranged along the center line connecting the circular conveyor line 1 and the oblong conveyor line 2. The first guide grooves 34 extend perpendicular to the center line connecting the circular conveyor line 1 and the oblong conveyor line 2. The number of first guide grooves 34 is equal to the number of first vibrating plates 32. The two ends of the first guide grooves 34 are respectively a first feed end and a first discharge end. The outlets of the plurality of first vibrating plates 32 are respectively connected to the first feed ends of the plurality of first guide grooves 34 in a one-to-one correspondence. The fourth manipulator 30 is used to remove the base from the first discharge end and load it into the circular conveyor line 1. The plurality of first vibrating plates 32 are respectively used for vibrating and feeding the bases of high-voltage connection units of different specifications. The bases enter the first guide grooves 34 from the outlets of the first vibrating plates 32. Due to the action of the first belt conveyor 33, the bases move along the first guide grooves 34. The widths of the plurality of first guide grooves 34 are adapted to the widths of the bases of the plurality of high-voltage connection units of different specifications, thereby enabling the loading of bases of various high-voltage connection units. At the same time, multiple first vibration plates 32 are arranged in one place, which makes it convenient for operators to add bases to the first vibration plates 32 .

[0040] In this embodiment, if Figure 1 As shown, the shell assembly machine 4 may include a shell loader 35 and a fifth manipulator 36 that reciprocates between the shell loader 35 and the oblong conveyor line 2; the shell loader 35 includes a second guide 37, a plurality of second vibration plates 38 arranged in sequence along the direction perpendicular to the center line of the circular conveyor line 1 and the oblong conveyor line 2, and a second belt conveyor line 39 extending along the direction perpendicular to the center line of the circular conveyor line 1 and the oblong conveyor line 2; as shown Figure 7As shown, the second guide member 37 has a plurality of second guide slots 40 arranged along the center line connecting the circular conveyor line 1 and the oblong conveyor line 2. The second guide slots 40 extend perpendicular to the center line connecting the circular conveyor line 1 and the oblong conveyor line 2. The number of second guide slots 40 is equal to the number of second vibrating plates 38. The two ends of the second guide slots 40 are respectively a second feed end and a second discharge end. The outlets of the plurality of second vibrating plates 38 are respectively connected to the second feed ends of the plurality of second guide slots 40 in a one-to-one correspondence. The fifth manipulator 36 is used to remove the housings from the second discharge ends and load them into the oblong conveyor line 2. The plurality of second vibrating plates 38 are respectively used for vibrating and feeding the housings of high-voltage connection units of different specifications. The housings enter the second guide slots 40 from the outlets of the second vibrating plates 38. Due to the action of the second belt conveyor 39, the housings move along the second guide slots 40. The widths of the plurality of second guide slots 40 are adapted to the widths of the housings of the plurality of high-voltage connection units of different specifications, thereby enabling the loading of housings of various high-voltage connection units. At the same time, multiple second vibrating plates 38 are arranged in one location, making it easier for operators to refill the second vibrating plates 38. Furthermore, the shell loader 35 and the base loader 29 are located on the same side of the line connecting the centers of the circular conveyor line 1 and the oblong conveyor line 2; a maintenance access is provided between the shell loader 35 and the base loader 29. The centralized arrangement of the first vibrating plates 32 and the second vibrating plates 38 reduces the distance operators travel when refilling materials. The maintenance access facilitates both refilling and repair work for maintenance personnel.

[0041] In this embodiment, if Figure 8As shown, the terminal insertion machine 12 includes a transverse robot arm 41, a lifting robot arm 42 fixed to the output end of the transverse robot arm 41, and a terminal clamp 43 and a terminal press head 44 both fixed to the output end of the lifting robot arm 42; the terminal press head 44 includes a press head body 45 that slides vertically, and a pressure sensor 46 connected to the output end of the lifting robot arm 42 and the press head body 45 at both ends; the terminal clamp 43 picks up the terminal, and the transverse robot arm 41 and the lifting robot arm 42 cooperate to drive the terminal clamp 43 to insert the picked terminal into a part of the base, and then the transverse robot arm 41 moves so that the terminal press head 44 is opposite to the terminal inserted into the base, and the lifting robot arm 42 drives the terminal press head 44 to move downward, gradually pressing the terminal into the base and into place. On the one hand, there is a tolerance in the length of the terminal itself. On the other hand, it is impossible for the terminal clamping claw 43 to just touch the shoulder of the terminal. If the terminal is directly inserted into the base by the terminal clamping claw 43, it is impossible to judge whether the terminal is actually in place. On the other hand, the friction between the terminal and the clamping claw is less than the friction between the terminal and the base, that is, after the insertion force, sliding friction will occur between the terminal clamping claw 43 and the terminal, causing damage to the terminal plating. Therefore, only the guide part of the terminal is inserted into the base by the terminal clamping claw 43, and then the terminal is inserted into place by the terminal pressing head 44. The pressure sensor 46 is used to monitor the pressing force during the terminal pressing process. On the one hand, it can detect abnormal terminal insertion. On the other hand, when the terminal is inserted into place, the pressing force will change sharply. This signal can be used as a signal that the terminal is pressed into place, overcoming the difficulty of not knowing how to know whether the terminal is actually in place. In this embodiment, if Figure 9 As shown, the terminal insertion machine 12 may also include a terminal cutting device 47. The terminal cutting device 47 may include a third guide member 49 having a third guide groove 48, a cutting device 50 for cutting the terminal strip in the guide groove, and a feeding device 51 for driving the terminal strip to intermittently move along the guide groove at a set step distance; the top of the third guide groove 48 is open to allow the terminal to extend out of the guide groove. Since the top of the third guide groove 48 is open, the terminal can extend upward to the outside of the third guide groove 48; the terminal extending out of the third guide groove 48 can be clamped by the terminal clamp 43 and then sent to the base in the circular conveyor line 1 to achieve online cutting, eliminating the intermediate terminal handling process. The cutting device 50 can be a punch 52 and an insert 53 respectively arranged on both sides of the third guide groove 48. The specific structure is similar to that of the existing stamping die and will not be repeated here.

[0042] In this embodiment, if Figure 1 、 Figure 10 and Figure 11As shown, the sealing ring assembly machine 5 may include a sealing ring loader 54, a fourth guide member 55 extending in the direction of the vertical circular conveyor line 1 and the center line connecting the oblong conveyor line 2, a linear vibrator 56 driving the fourth guide member 55, and a sixth manipulator 57 for loading the sealing ring in the fourth guide member 55 into the oblong conveyor line 2; the protective cover assembly machine 6 may include a protective cover loader 58, a fifth guide member 59, a fourth belt conveyor line 60 extending in the direction of the vertical circular conveyor line 1 and the center line connecting the oblong conveyor line 2, and a seventh manipulator 61 for loading the protective cover in the fourth belt conveyor line 60 into the oblong conveyor line 2; the sealing ring loader 54 includes a first shaking plate 62 and an eighth manipulator 63 for placing the sealing ring in the first shaking plate 62 into the fourth guide member 55; the protective cover loader 58 includes a second shaking plate 64 and a ninth manipulator 65 for placing the protective cover in the second shaking plate 64 into the fourth belt conveyor line 60; the eighth manipulator 63 and the ninth manipulator 65 are the same manipulator. Since the eighth manipulator 63 and the ninth manipulator 65 are the same manipulator, the manipulator utilization rate is higher and costs are greatly saved. Furthermore, the fourth guide member 55 has a plurality of fourth guide slots 66 arranged along the direction of the center line connecting the circular conveyor line 1 and the oblong conveyor line 2; the fifth guide member 59 has a plurality of fifth guide slots 67 arranged along the direction of the center line connecting the circular conveyor line 1 and the oblong conveyor line 2. The first shaking plate 62 and the second shaking plate 64 use visual recognition to cooperate with the manipulator to achieve flexible loading, that is, to respectively load the sealing rings and protective covers of various high-voltage connection units of different specifications; the widths of the plurality of fourth guide slots 66 are respectively adapted to the widths of the sealing rings of high-voltage connection units of different specifications; the widths of the plurality of fifth guide slots 67 are respectively adapted to the widths of the protective covers of high-voltage connection units of different specifications, thereby broadening the versatility of the high-voltage connection unit production system, meeting the assembly and testing requirements of various high-voltage connection units of different specifications, and improving equipment utilization.

[0043] In some specific embodiments, Figure 12 and Figure 13 As shown, the lock assembly machine may include a lock feed channel 68, a pressing mechanism 69 provided on the oblong conveyor line and used to press the shell, and a tenth manipulator 70 for taking out the lock at the outlet of the lock feed channel 68 and inserting it into the shell, as shown in FIG. Figure 13As shown, the tenth manipulator 70 may include a manipulator body 71, a base 72 provided at the output end of the manipulator body 71, a fixed claw 73 provided on the base 72 for lifting, a first lifting cylinder 74 provided on the base 72, an inclined wedge 75 fixed to the base 72, a movable claw 76 hinged to the fixed claw 73 in the middle, a return spring 77 provided between the movable claw 76 and the fixed claw 73, and a push rod 78 provided between the movable claw 76 and the fixed claw 73. The push rod 78 is connected to a second lifting cylinder 79 that drives it to rise and fall in the fixed claw 73. The movable claw 76 has a protrusion 80 corresponding to the inclined wedge 75 at the lower part; when the tenth manipulator 70 is in the material picking mode, the return spring 77 is used to drive the movable claw 76 to close to clamp the lock; when the tenth manipulator 70 is in the assembly mode, the first lifting cylinder 74 is used to lift the fixed claw 73 until the protrusion 80 contacts the inclined wedge 75 to open the movable claw 76, and the second lifting cylinder 79 is used to lift the push rod 78 to fully insert the lock into the shell. The lock buckle feed channel 68 can be fed into the space between the movable jaw 76 and the fixed jaw 73 by a vibrating feeder or other means. For example, the lock buckle feed channel 68 may include a vibrating feeder and a guide member disposed on the vibrating feeder, with a material trough defined in the guide member. The cross-section of the material trough is adapted to the lock buckle. The specific structure is known and will not be described in detail here. The protrusion may be a roller such as a bearing to reduce wear. Since the lock is installed into the housing from below, the space is more limited compared to assembling from above. Therefore, the present invention cleverly arranges the movable fixed claw 73, the return spring 77 and the inclined wedge 75. Through the vertical displacement during the lock assembly process, the inclined wedge 75 acts on the protrusion 80 of the movable claw 76, and the movable claw 76 is radially expanded while the lock is pre-assembled. Thus, the two processes of lock pre-assembly and clamping jaw opening are integrated into a single motion stroke. The lock is then pushed completely into the housing by the push rod 78. At the same time, after the lock is assembled, the fixed claw 73 moves downward, and the protrusion 80 is separated from the inclined surface of the inclined wedge 75, and can be used to clamp the lock 82 again. Figure 13 As shown, when the tenth manipulator 70 is in the material picking mode, the opposing sides of the movable claw 76 and the fixed claw 73 and the top surface of the push rod 78 together form a positioning space for the positioning lock 82. The positioning space is connected to the material trough, and the lock enters the positioning space. The positioning space and the lock 82 can be clearance-matched to facilitate the lock 82 to smoothly enter the positioning space. To prevent the lock 82 from falling, a second stopper 81 can be provided at the end of the fixed claw 73 facing away from the lock feed channel 68. The tenth manipulator is a single-axis manipulator that drives the lock to move in a direction perpendicular to the opposing sides of the movable claw 76 and the fixed claw 73. Another optional method is to set the upper and lower ends of the inclined wedge as inclined surfaces, that is, the movable claw is also in an open state at the bottom, so that the lock can smoothly enter the positioning space. Then, the first lifting cylinder 74 drives the fixed claw to move up a short distance to disengage the bottom inclined surface, so that the fixed claw can clamp the lock 82. Another optional method is to set a dislocation mechanism at the outlet of the lock feed channel 68, so that the dislocation mechanism directly pushes the lock into the positioning space.

[0044] In this implementation, if Figure 1As shown, the housing assembly machine 4, leakage detection machine 9, and base assembly machine 10 are located on the same side of the center line connecting the circular conveyor line 1 and the oblong conveyor line 2. The sealing ring assembly machine 5, protective cover assembly machine 6, lock assembly machine 7, and terminal insertion machine 12 are located on the other side of the center line connecting the circular conveyor line 1 and the oblong conveyor line 2. The plug-in tester 8 is located at the end of the oblong conveyor line 2 facing away from the circular conveyor line 1, and the shield cover assembly machine 11 is located at the end of the circular conveyor line 1 facing away from the oblong conveyor line 2. This fully utilizes space, has a reasonable structural layout, and greatly facilitates refilling, repair, and maintenance.

[0045] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
