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

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0045] This invention provides a semi-automatic assembly device for energy storage sockets, such as... Figures 20 to 22 The energy storage socket includes a housing 100, an end cap 200, and a sleeve 300. The sleeve 300 includes a locking tongue end 400 and a tube end 500. The inner cavity of the tube end is provided with an anti-touch post 600 and a mesh sleeve 700 located on the outer periphery of the anti-touch post. The housing 100 includes a tube body 110 for fitting and locking onto the tube end and a rectangular mating part 120 provided on the tube body. An annular cavity for mounting the end cap is formed between the tube body and the tube end.

[0046] The energy storage socket requires several steps during assembly. First, the anti-touch post 600 and sleeve 300 are crimped together. Then, the mesh sleeve 700 is crimped into the annular cavity. Next, the sleeve 300 and housing 100 are crimped together, and finally, the end cap 200 is crimped together. This process involves multiple crimping operations. Traditionally, this is done manually using multiple crimping machines, resulting in very low efficiency and a low product qualification rate.

[0047] Designing this energy storage socket for an automated production line presents significant challenges. The first difficulty lies in the crimping assembly between the sleeve 300 and the anti-contact post 600. Traditional crimping methods using the anti-contact post 600 result in poor concentricity between the sleeve 300 and the anti-contact post 600, making it difficult to mount the rear mesh sleeve 700. Therefore, this design at the workstation during automated turnaround can lead to frequent downtime or excessively high rejection rates.

[0048] When performing pre-assembly inspection on the relative assembly accuracy of the anti-contact post 600 and the sleeve 300, it is necessary to meet the accuracy requirements for the subsequent mesh sleeve installation. If the inspection is too stringent, the NG rate will exceed 90%, making it impossible to maintain normal production. On the other hand, relaxing the inspection accuracy will cause the subsequent mesh sleeve 700 to fail to be installed, resulting in frequent downtime due to malfunctions.

[0049] In this case, if Figures 1 to 19 As shown, the semi-automatic assembly equipment includes a rotating pallet with several combined carriers 1, a first manual station 2 arranged sequentially along the rotation direction of the rotating pallet, an anti-touch column pressing and testing station 3, an anti-touch column NG unloading station 4, a second manual station 5, a mesh sleeve riveting station 6, a pull-out force testing station 7, a shell pre-assembly station 8, a shell riveting station 9, an end cap transfer pre-assembly station 10, and an end cap pressing station 11.

[0050] 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-collision post loading limiting groove 1011 and an annular guide groove 1012 for guiding the end of the sleeve. The second loading position 102 includes a locking tongue end limiting groove 1021 for mounting the locking tongue end. The third loading position 103 includes an end cap mounting groove 1031 for mounting the end cap.

[0051] The first manual position 2 is used for unloading semi-finished or finished products and for sequentially mounting anti-collision posts and sleeves on the first loading position 101.

[0052] The anti-touch column pressing test station 3 includes a pressing test device 30.

[0053] The anti-collision column NG unloading station 4 includes an anti-collision column unloading part 41 and a sleeve transfer mechanism 42 for rotating between the first loading position and the anti-collision column unloading part.

[0054] The second loading position 5 is used to flip the sleeve on the first loading position and mount it on the second loading position, and to mount a mesh sleeve on the end of the tube and an end cap on the third loading position.

[0055] The mesh sleeve riveting station 6 includes a mesh sleeve riveting device 60 for mesh sleeve riveting and mating.

[0056] Pull-out force testing station 7 includes a pull-out force testing device 70 for performing pull-out force testing on the inner wall of the mesh sleeve.

[0057] The shell pre-assembly station 8 includes a shell feeding device 80 for pre-assembly of shells.

[0058] The housing riveting station 9 includes a housing riveting device 90 for housing riveting and mating.

[0059] The end cap transfer pre-assembly station 10 includes an end cap transfer device 12, which includes a transfer pre-assembly mechanism 121 for transferring the end caps on the third loading station to the second loading station for pre-assembly.

[0060] The end cap pressing station 11 includes an end cap pressing device 13 for pressing and mating end caps.

[0061] Detailed implementation process and principle explanation: When the semi-automatic assembly equipment is running, manual operation is performed at the first manual station 2 to unload the material at the second loading station 102. The anti-collision column 600 and sleeve 300 are sequentially mounted on the first loading station 101.

[0062] During assembly, the rod end of the anti-collision post 600 is inserted into the anti-collision post loading and limiting groove 1011 for precise positioning. Then, the sleeve end 500 of the sleeve 300 is loaded into the annular guide groove 1012, which provides a downward stroke for the sleeve end 500 to be crimped. This satisfies the relative assembly accuracy between the anti-collision post 600 and the sleeve 300.

[0063] The rotating tray switches to the anti-collision post pressing test station 3. At this time, the pressing test device 30 presses down on the locking tongue end 400, so that the sleeve and the anti-collision post are pressed together. It should be noted that during the pressing operation, the current assembly of the sleeve and the anti-collision post is tested by pressure and / or stroke detection. Generally, after guidance, the relative position of the two is guaranteed, but the workpiece has a certain tolerance. When the peak value of the pressing pressure is too high, it is judged as NG. Alternatively, stroke monitoring can be used. If the specified stroke is not reached, it is judged as NG. The two can also be combined for NG judgment.

[0064] After the pressure and testing, the station is switched to the anti-collision column NG unloading station 4. The NG products are unloaded according to the test results. The sleeve transfer mechanism 42 picks up the material and transfers it to the anti-collision column unloading section 41 for unloading.

[0065] The assembled sleeve is moved to the second manual position 5. At this time, the manual person flips the sleeve and positions and inserts its locking tongue end 400 into the locking tongue end limiting groove 1021 to achieve precise positioning and mounting. Then, the mesh sleeve is manually loaded between the inner ring wall of the sleeve end 500 and the anti-collision post. At this time, the position is adjusted manually to ensure that the mesh sleeve can be embedded. Then, the end cap 200 is placed on the end cap mounting groove 1031.

[0066] The second manual station 5 is explained as follows: during operation, there may be a situation where the sleeve is removed but the anti-collision column remains. In this case, the second manual station 5 does not need to perform the sleeve flipping operation, but can remove the current anti-collision column.

[0067] After the second work station 5 completes the mounting and pre-assembly, it moves to the mesh sleeve riveting station 6. At this time, the mesh sleeve riveting device 60 presses the mesh sleeve into place and then moves to the pull-out force testing station 7 for pull-out force testing. The pull-out fit test associated with the mesh sleeve is carried out through the pull-out force testing device 70.

[0068] If the pull-out force test fails, there will be no assembly action when passing through the subsequent workstations until the first workstation unloads the material.

[0069] When the pull-out force test is qualified, the switching position passes through the housing pre-assembly station 8 and the housing riveting station 9 in sequence. The housing feeding device 80 pre-assembles the housing onto the sleeve 300, and the housing riveting device 90 rivets the housing so that the sleeve and the housing are assembled together.

[0070] Then, end cap assembly is performed. When the end cap is transferred to the pre-assembly station 10, the transfer pre-assembly mechanism 121 picks up the end cap on the third loading position and transfers it to the annular cavity of the second loading position to achieve pre-assembly. Then, the end cap pressing device 13 of the end cap pressing station 11 performs the end cap pressing operation.

[0071] The final finished product is moved to the first manual station 2 for unloading from the second loading station. During unloading, the product is visually categorized based on whether it contains a casing or whether there are any remaining end caps. This avoids identification errors. End caps at the current third loading station do not need to be unloaded. When the product reaches the second manual station, if end caps are present, no further manual loading is required.

[0072] In one specific embodiment, Figures 1 to 19 As shown, the pressing detection device 30 includes a pressing detection end 301 with lifting displacement for pressing the end of the locking tongue. The pressing detection end is connected to a pressure sensor, and the pressing detection device 30 also includes a distance sensor for monitoring the stroke of the pressing detection end 301.

[0073] This ensures testing accuracy, prevents defective products from entering subsequent assembly processes, and reduces the risk of downtime due to malfunctions.

[0074] The sleeve transfer mechanism 42 includes an anti-collision column transfer slide 421 with linear displacement, and a sleeve clamp 422 for clamping or releasing the sleeve is provided on the anti-collision column transfer slide.

[0075] The mesh sleeve riveting device 60 includes a mesh sleeve riveting end 61 with lifting displacement for crimping the mesh sleeve, which can be used for any structure that can be crimped into place.

[0076] The pull-out force testing device 70 includes a sleeve limiting part 71 with lifting displacement for pressing and locking the sleeve, and a tubular detection end 72 with lifting displacement for probing into the mesh sleeve.

[0077] This satisfies the requirement for stable and reliable pull-out force testing.

[0078] The shell loading device 80 includes a shell picking mechanism 81 with a turnover displacement, which picks up and transfers shells for pre-installation.

[0079] The housing crimping device 90 includes a housing crimping end 91 for crimping rectangular mating parts, and the housing crimping end has a clearance channel to avoid the sleeve body; thus satisfying the crimping requirements of housing assembly.

[0080] The end cap pressing device 13 includes an end cap pressing end 111 with lifting displacement for pressing the end cap, and the final assembly is achieved by pressing the end cap through the end cap pressing end 111.

[0081] In one specific embodiment, the first loading position 101 includes a central column 1013 located in an annular guide groove, an anti-collision column loading limiting groove is disposed in the central column, and at least one axial limiting groove 1014 is provided on the outer peripheral wall of the central column.

[0082] The axial limiting groove 1014 design enables circumferential guidance for the mounting of the sleeve 300, further precise displacement guidance in the pressing direction, and ensures reliable and stable assembly accuracy.

[0083] In one specific embodiment, such as Figure 11 As shown, the first manual station 2 also includes an unloading conveyor line.

[0084] Of course, the first work station 2 also includes the sleeve 300 feeding section and the anti-collision column 600 feeding section. The unloading conveyor line can also adopt the design of NG conveyor belt and good product conveyor belt to meet the operation requirements of the first work station 2.

[0085] In one specific embodiment, the four corners of the rectangular mating part are respectively provided with assembly channels, and a bushing 800 is provided in any assembly channel.

[0086] Before the shell is loaded, the bushing 800 needs to be assembled. However, the number of workstations on the rotating pallet is limited, and the space for the first and second workstations needs to be accommodated. Therefore, the shell assembly device is designed.

[0087] like Figures 11 to 19 As shown, the shell pre-assembly station 8 includes a shell assembly device 82. The shell assembly device 82 includes a rotating platform with several shell carriers 821, a bushing loading station 822, a shell loading station 823, a shell pressing station 824, and a shell transfer station 825 arranged sequentially along the rotation direction of the rotating platform. The shell loading device 80 includes a shell picking mechanism 81 for rotating between the shell transfer station and the shell pre-assembly station.

[0088] The housing carrier 821 includes a loading cavity 8211 that mates with the rectangular mating part. The loading cavity is provided with four bushing pre-installation guide posts 8212 for correspondingly mounting bushings and housing guide posts 8213 for guiding the housing to be mounted.

[0089] The bushing loading station 822 includes a bushing supply device 8221 and a bushing handling and pre-assembly mechanism 8222 for bushing turnover between the bushing supply device and the housing carrier.

[0090] The shell loading station 823 includes a shell supply device 8231 and a shell handling and pre-assembly mechanism 8232 for shell turnover between the shell supply device and the shell carrier.

[0091] The housing pressing station 824 includes a housing pressing mechanism 8241 with lifting displacement, and the housing pressing mechanism has a housing pressing block 8242 for pressing onto the rectangular mating part.

[0092] Detailed implementation process and principle explanation: First, the bushing supply device feeds the bushing. After the bushing handling and pre-assembly mechanism 8222 picks up the bushing, it is positioned and guided on the bushing pre-assembly guide column 8212.

[0093] The housing handling and pre-loading mechanism 8232 picks up the housing from the housing supply device 8231 and loads it onto the loading slot 8211. The housing guide column 8213 provides relative positional guidance, and there is a certain descent stroke space.

[0094] The shell pressing block 8242 presses the shell together to achieve assembly.

[0095] In one specific embodiment, a shell assembly detection mechanism 83 is provided between the shell transfer station and the shell pre-assembly station, located on the displacement path of the shell picking mechanism.

[0096] The housing assembly and testing mechanism 83 includes a support base 831, on which a testing channel 832 is provided corresponding to the bushing, and a testing contact end 833 with floating displacement is provided in any testing channel.

[0097] During the transfer of the assembled housing, the housing picking mechanism picks up the housing and places it on the carrier 831 for testing. The testing contact end 833 is subjected to pressure and moves downward. When the position exceeds the detection range, it is judged as NG, and NG is unloaded on the turnover path of the housing picking mechanism.

[0098] In one specific embodiment, the bushing supply device 8221 includes a bushing vibration chamber and a bushing direct vibration supply mechanism connected to the discharge end of the bushing vibration chamber. The discharge end of the bushing direct vibration supply mechanism is provided with a bushing transfer table having a horizontal linear switching displacement. The bushing transfer table has a bushing receiving station opposite to the discharge end of the bushing direct vibration supply mechanism and a bushing offset feeding station offset from the discharge end of the bushing direct vibration supply mechanism. The bushing direct vibration supply mechanism includes two parallel and spaced direct vibration tracks. The bushing transfer table is provided with two bushing loading grooves that correspond one-to-one with the direct vibration tracks.

[0099] The bushing handling and pre-assembly mechanism includes a bushing picking claw, which has two picking parts that correspond one-to-one with the bushing loading groove.

[0100] Materials are received at the bushing receiving station, and the bushing misalignment feeding station provides picking space for the bushing handling pre-assembly mechanism to meet picking requirements.

[0101] In one specific embodiment, the shell supply device includes a shell vibration chamber and a shell direct vibration supply mechanism connected to the discharge end of the shell vibration chamber. The discharge end of the shell direct vibration supply mechanism is provided with a shell transfer platform with horizontal linear switching displacement. The shell transfer platform has a shell receiving station opposite to the discharge end of the shell direct vibration supply mechanism and a shell offset supply station offset from the discharge end of the shell direct vibration supply mechanism.

[0102] The housing handling pre-assembly mechanism includes a housing picking claw, which includes at least three radially displaced claw portions evenly distributed circumferentially.

[0103] The misaligned feeding position of the housing provides a picking space for the housing's picking claws.

[0104] In one specific embodiment, the housing loading station 823 includes a housing position adjustment mechanism 84 located between the housing misalignment feeding station and the rotating platform and on the turnover path of the housing handling pre-assembly mechanism.

[0105] The housing position adjustment mechanism 84 includes a position adjustment carrier 841 with rotational displacement, and the position adjustment carrier is provided with at least two alignment adjustment pins 842 corresponding to the bushing.

[0106] This allows for positional adjustment, ensuring precise positioning of the supplied housing, guaranteeing the relative position of the housing and bushing during loading, and ensuring a high rate of qualified housing assembly.

[0107] The above description shows that the system enables the assembly and forming of energy storage sockets. Manual workstations are used for the sequential assembly and flipping of sleeves during pre-assembly, maintaining the continuous and stable operation of the semi-automatic production line.
