Description

Technical Field

[0001] This invention relates to a semi-automatic assembly device for energy storage sockets, belonging to the technical field of assembly equipment for energy storage sockets in new energy vehicle connectors. Background Technology

[0002] New energy vehicle connectors are key electromechanical components used to realize the transmission and control of electrical energy and signals inside and outside new energy vehicles. They are bridges connecting core components such as batteries, motors, electronic controls, charging systems, and vehicle wiring harnesses. They must meet the stringent requirements of high voltage, high current, vibration resistance, and high and low temperature resistance, which is different from the connectors of traditional fuel vehicles that mainly transmit signals at low voltage.

[0003] Currently, a type of energy storage socket is involved, such as Figures 20 to 22 As shown, it includes a housing, an end cap, and a sleeve. The sleeve includes a locking tongue end and a tube end. The inner cavity of the tube end is provided with an anti-touch post and a mesh sleeve located on the outer periphery of the anti-touch post. The housing includes a tube body for fitting and locking onto the tube end and a rectangular mating part provided on the tube body. An annular cavity for mounting the end cap is formed between the tube body and the tube end.

[0004] The assembly of this energy storage socket involves several steps: crimping the anti-collision posts to the sleeves, crimping the mesh sleeves to the sleeves, crimping the housing to the sleeves, and crimping the end caps within the annular cavity. Furthermore, to reduce the scrap rate, inspection is required after each crimping step, resulting in a large number of workstations involved.

[0005] In traditional assembly operations, manual crimping is typically performed after each assembly using a crimping mechanism. At the same time, manual quality inspection is also required, making it difficult to guarantee assembly efficiency and product quality.

[0006] To address this issue, a self-developed linear production line employs a carrier-based design for sequential station switching to achieve automated operation. Traditional carriers typically use a mounting method targeting the locking tongue end, with the sleeve end facing upwards. In this case, the sequential pressing of the anti-collision post and the mesh sleeve is in the same direction. However, the pressing and assembly of the anti-collision post in this direction presents a difficult-to-control machining bias, making it hard to automatically adjust the mounting position of the mesh sleeve. This results in frequent production line downtime or excessively high NG (no-response) rates, preventing the linear production line from operating normally. Summary of the Invention

[0073] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0074] The present application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0075] The present application provides a kind of semi-automatic assembly equipment of energy storage socket, such as Figures 20 to 22 Energy storage socket includes shell 100, end cover 200, sleeve 300, sleeve 300 includes lock tongue end 400 and pipe sleeve end 500, the inner cavity of pipe sleeve end is provided with anti-touch column 600 and grid sleeve 700 located in the outer periphery of anti-touch column, shell 100 includes pipe sleeve body 110 for sleeving locking in pipe sleeve end, rectangular adapter 120 is arranged on pipe sleeve body, and annular cavity for carrying end cover is formed between pipe sleeve body and pipe sleeve end.

[0076] When the energy storage socket is assembled, the anti-touch column 600 and the sleeve 300 need to be crimped and assembled, then the grid sleeve 700 is embedded and crimped in the annular cavity, and then the sleeve 300 and the shell 100 are crimped and assembled, and finally the end cover 200 is crimped and assembled. There are multiple crimping operations. In the traditional process, manual crimping is carried out through multiple crimping devices, the efficiency is very low, and the product qualification rate is also relatively low.

[0077] When the energy storage socket is designed into an automatic production line, there are great difficulties. The first difficulty is the crimping assembly between the sleeve 300 and the anti-touch column 600. The traditional crimping method of picking up the anti-touch column 600 will cause poor relative concentricity between the sleeve 300 and the anti-touch column 600, and it is difficult to realize the carrying of the rear grid sleeve 700. Therefore, after the design of this station in the automatic turnover process, frequent downtime or high NG rate will be caused.

[0078] When the pre-positioned detection of the relative assembly accuracy of the anti-touch column 600 and the sleeve 300 is adopted, the requirement accuracy of the subsequent grid sleeve latching needs to be met. At this time, too strict detection will cause the NG rate to exceed 90%, which cannot maintain normal production, and relaxing the detection accuracy will cause the subsequent grid sleeve 700 to be unable to be latched, resulting in frequent failure stop.

[0079] In the present case, as shown in Figures 1 to 19 The semi-automatic assembly equipment includes a rotating tray with a plurality of combined carriers 1, a first manual position 2 arranged in sequence along the rotating direction of the rotating tray, an anti-touch column pressing detection position 3, an anti-touch column NG unloading position 4, a second manual position 5, a grid sleeve riveting position 6, a pulling force test position 7, a shell pre-assembly position 8, a shell riveting position 9, an end cover transfer pre-assembly position 10, and an end cover pressing position 11.

[0080] The combined carrier 1 includes a first loading position 101, a second loading position 102, and a third loading position 103. The first loading position 101 includes an anti-touch column loading limiting groove 1011 and an annular guide groove 1012 for guiding the sleeve end. The second loading position 102 includes a lock tongue end limiting groove 1021 for latching the lock tongue end. The third loading position 103 includes an end cover latching groove 1031 for latching the end cover.

[0081] The first manual position 2 is used for unloading semi-finished products or finished products and sequentially latching the anti-touch column and the sleeve on the first loading position 101.

[0082] The anti-touch column pressing detection position 3 includes a pressing detection device 30.

[0083] The anti-touch column NG unloading position 4 includes an anti-touch column unloading part 41 and a sleeve transfer mechanism 42 for transferring between the first loading position and the anti-touch column unloading part.

[0084] The second manual position 5 is used for latching the sleeve on the second loading position after turning over the sleeve on the first loading position, latching the grid sleeve on the sleeve end, and latching the end cover on the third loading position.

[0085] The grid sleeve riveting position 6 includes a grid sleeve riveting device 60 for grid sleeve riveting connection.

[0086] The pulling force test position 7 includes a pulling force test device 70 for pulling force test on the inner cavity wall of the grid sleeve.

[0087] The shell pre-assembly position 8 includes a shell feeding device 80 for shell feeding pre-assembly.

[0088] The shell riveting position 9 includes a shell riveting device 90 for shell riveting connection.

[0089] The end cap transfer pre-assembly station 10 comprises an end cap transfer device 12, which comprises a transfer pre-assembly mechanism 121 for transferring the end cap on the third loading position to the second loading position for pre-assembly.

[0090] The end cap crimping station 11 comprises an end cap crimping device 13 for end cap crimping.

[0091] The specific implementation process and principle are described as follows:

[0092] During the operation of the semi-automatic assembly equipment, manual work is performed at the first manual position 2, the material on the second loading position 102 is unloaded, and the anti-touch column 600 and the sleeve 300 are sequentially loaded on the first loading position 101.

[0093] During the loading process, the rod end of the anti-touch column 600 is inserted into the anti-touch column loading limiting groove 1011 to achieve precise positioning and loading, and the sleeve end 500 of the sleeve 300 is loaded on one side of the annular guide groove 1012, and the annular guide groove 1012 has a sleeve end 500 descending stroke for crimping. In this way, the relative assembly precision between the anti-touch column 600 and the sleeve 300 is satisfied.

[0094] The rotating tray switching position is switched to the anti-touch column crimping detection station 3, at this time, the crimping detection device 30 presses down the lock tongue end 400, so that the sleeve and the anti-touch column are crimped and assembled into one, it should be noted that during the crimping operation, the current sleeve and anti-touch column assembly are detected by pressure and / or stroke detection, generally, after being guided, the relative positions of the two are guaranteed, and there is a certain tolerance in the workpiece, when the pressure peak value of the pressing down is too high, it is judged as NG, it can also be judged as NG by stroke monitoring, when the specified stroke is not reached, and the two can also be combined for NG judgment.

[0095] After crimping and detection, the position is switched to the anti-touch column NG unloading station 4, and the NG product is unloaded according to the detection result, the sleeve transfer mechanism 42 picks up the material and transfers it to the anti-touch column unloading part 41 for unloading.

[0096] The assembled qualified sleeve is displaced to the second manual position 5, at this time, the sleeve is flipped by manual work, the lock tongue end 400 is positioned and inserted into the lock tongue end limiting groove 1021 to achieve precise positioning and loading, then the grid sleeve is manually loaded between the inner ring wall of the sleeve end 500 and the anti-touch column, at this time, the position degree is adjusted by manual work to ensure that the grid sleeve can be embedded and loaded, and then the end cap 200 is placed on the end cap loading groove 1031.

[0097] The second manual position 5 is described, in the running process, there is a situation that the sleeve is removed and the anti-touch column is retained, at this time, the second manual position 5 does not need to perform the flipping operation of the sleeve, and the current anti-touch column is removed.

[0098] After the second artificial position 5 completes the mounting and pre-assembly, it is displaced to the grid sleeve riveting and pressing station 6. At this time, the grid sleeve riveting and pressing device 60 presses the grid sleeve into place and then moves to the pull-out force testing station 7 for pull-out force testing. The pull-out force testing device 70 is used for pull-out force testing associated with the grid sleeve.

[0099] If the pull-out force testing is not qualified, no assembly action is performed when passing through the subsequent stations until the first artificial position performs unloading.

[0100] When the pull-out force testing is qualified, the switching position sequentially passes through the shell pre-assembly station 8 and the shell riveting and pressing station 9. The shell loading device 80 pre-assembles the shell onto the sleeve 300, and the shell riveting and pressing device 90 performs riveting and pressing on the shell, so that the sleeve and the shell are assembled and integrated.

[0101] Then, the end cap assembly is performed. When the end cap transfer pre-assembly station 10 is reached, the transfer pre-assembly mechanism 121 picks up the end cap on the third loading position and transfers and mounts it into the annular cavity of the second loading position to achieve pre-assembly. Then, the end cap riveting and pressing device 13 of the end cap riveting and pressing station 11 performs end cap riveting and pressing operation.

[0102] Finally, the finished product is displaced to the first artificial position 2 for unloading of the product on the second loading position. At this time, during unloading, visual identification classification is performed according to whether the current product contains a shell. Classification can also be performed according to whether there is a residual end cap. In this way, identification errors do not occur. The end cap on the third loading position does not need to be unloaded. When the second artificial position is reached, if there is an end cap, it does not need to be manually reloaded.

[0103] In one specific embodiment, Figures 1 to 19 As shown, the riveting and pressing detection device 30 includes a riveting and pressing detection end 301 for riveting and pressing the lock tongue end, which has lifting displacement. The riveting and pressing detection end is connected with a pressure sensor. The riveting and pressing detection device 30 further includes a distance sensor for monitoring the stroke of the riveting and pressing detection end 301.

[0104] In this way, detection accuracy is ensured, and the risk of failure stoppage is reduced.

[0105] The sleeve transfer mechanism 42 includes a touch-proof column transfer sliding seat 421 with linear displacement, and a sleeve clamp 422 for clamping or releasing the sleeve is arranged on the touch-proof column transfer sliding seat.

[0108] Thus, the stable and reliable requirement of the pull-out force test is met.

[0110] The shell riveting device 90 comprises a shell riveting end 91 for riveting the rectangular adapter. The shell riveting end 91 is provided with an avoidance channel for avoiding the sleeve body. Thus, the riveting requirement of the shell assembly is met.

[0111] The end cover pressing device 13 comprises an end cover pressing end 111 for riveting the end cover, which is provided with a lifting displacement. The riveting of the end cover by the end cover pressing end 111 realizes the final assembly and forming.

[0112] In one embodiment, the first loading position 101 comprises a central column 1013 located in the annular guide groove. A touch-proof column loading limiting groove is arranged in the central column. At least one axial limiting groove 1014 is arranged on the outer peripheral wall of the central column.

[0113] Through the design of the axial limiting groove 1014, the loading circumferential guidance of the sleeve 300 is realized, the further accurate displacement guidance in the riveting direction is realized, and the assembly precision is ensured to be reliable and stable.

[0114] In one embodiment, as shown in Figure 11 the first manual position 2 further comprises a discharging conveying line.

[0115] Of course, the first manual position 2 further comprises a sleeve 300 loading part and a touch-proof column 600 loading part. The discharging conveying line can also adopt the design of an NG conveying belt and a good product conveying belt to meet the operation requirement of the first manual position 2.

[0116] In one embodiment, the four corner ends of the rectangular adapter are respectively provided with an assembly channel. A bushing 800 is arranged in any assembly channel.

[0117] That is, the assembly of the bushing 800 is required before the loading of the shell. The workstations of the rotary tray are limited, and the space deployment of the first manual position and the second manual position also needs to be met. Therefore, the design of the shell assembly device is adopted.
