Description

Technical Field

[0001] This invention relates to a fully automated pressing and assembly equipment for energy storage plugs, belonging to the technical field of automated pressing and assembly equipment for energy storage plugs 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, there is an assembly method for energy storage plugs, such as... Figure 27 and Figure 28 As shown, the assembly includes a housing, a conductive post, a U-shaped button, a sealing ring, a sleeve, and an end cap. The housing includes a shaft tube end, a button groove, and a loading cavity. The conductive post includes a post tube end and a nose end. During assembly, the nose end of the conductive post is required to be embedded in the loading cavity for assembly and locking. The U-shaped button is embedded and fastened in the button groove, and the sealing ring is sleeved on the shaft tube end. The sleeve is embedded in the shaft tube end, and the end cap is pressed onto the free end of the shaft tube end. The assembly operation is relatively complex and requires high precision in pressing and fitting the conductive post, U-shaped button, sleeve, and end cap, making it difficult to achieve fully automated assembly.

[0004] In traditional assembly processes, conductive posts and U-shaped buttons are typically assembled using manual feeding and pressing methods, while sealing rings are assembled using a semi-manual method with the aid of fixtures. The pressing of sleeves and end caps also requires manual guidance. In automated designs, there are also automated feeding and operation designs for sleeves and end caps, but this can lead to frequent shutdowns, affecting the continuous and stable operation of automated assembly.

[0005] The current assembly equipment uses a combination of pressing equipment and production line. The automation part can realize the automated pre-assembly of parts. Pressing stations need to be set up on the production line, and pressing and visual inspection are carried out by manual intervention. When feeding U-shaped buttons, conductive pins, sleeves, end caps and sealing rings, parts often fall off. Therefore, the station design often requires manual replenishment to maintain the normal operation of the production line. This type of production line layout occupies a lot of space, has high labor costs, and insufficient product assembly stability. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art and to propose a fully automated pressing and assembly equipment for energy storage plugs, which addresses many problems in traditional assembly lines, such as the large number of manual positions, large space occupation in the production line layout, low efficiency of production line operation during assembly and switching, and unstable product assembly quality.

[0065] 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.

[0066] 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.

[0067] This invention provides a fully automated pressing and assembly device for energy storage plugs, such as... Figure 27 and Figure 28As shown, the assembly includes a housing 100, a conductive post 200, a U-shaped button 300, a sealing ring 400, a sleeve 500, and an end cap 600. The housing 100 includes a shaft tube end 1001, a button groove 1002, and a loading cavity 1003. The conductive post 200 includes a post tube end 2001 and a nose end 2002. During assembly, the nose end 2002 of the conductive post is required to be embedded in the loading cavity for assembly and locking. The U-shaped button 300 is embedded and fastened in the button groove, and the sealing ring 400 is sleeved on the shaft tube end 1001. The sleeve 500 is embedded in the shaft tube end 1001, and the end cap 600 is pressed onto the free end of the shaft tube end 1001. The assembly operation is relatively complex. Traditional assembly equipment cannot achieve automated assembly and forming. It generally adopts a combination of automatic and manual workstations on a linear conveying path, which has low operating efficiency and makes it impossible to control the product assembly quality.

[0068] In this case, if Figures 1 to 26 As shown, the fully automatic pressing and assembly equipment includes a first assembly device 1, a second assembly device 2, a third assembly device 3, and an insertion / extraction force detection and unloading device 4.

[0069] The first assembly device 1 includes a first rotating pallet 12 with several first sets of loading devices 11, a housing loading station 13, a conductive pile loading station 14, a conductive pile pushing and assembly station 15 for supplying and horizontally pushing conductive piles, and a first housing transfer station 16 arranged sequentially along the rotation direction of the first rotating pallet. The first set of loading devices 11 includes at least one first bearing position, and the first bearing position includes a first housing loading groove 111 and a conductive pile guide loading groove 112 connected to the first housing loading groove.

[0070] The second assembly device 2 includes a second rotating tray 22 with several second sets of loading devices 21, a second housing transfer station 23 arranged sequentially along the rotation direction of the second rotating tray 22, a sealing ring feeding and assembly station 24, a button feeding and pushing assembly station 25 for button supply and horizontal pushing, and a third housing transfer station 26. The second set of loading devices 21 includes at least one second bearing position, and the second bearing position includes a second housing loading groove 211 opposite to the direction of the first housing loading groove.

[0071] The third assembly device 3 includes a third rotating pallet 32 ​​with several third loading devices 31, a fourth housing transfer station 33 arranged sequentially along the rotation direction of the third rotating pallet 32, a sleeve loading pre-assembly station 34 with sleeve concentricity guidance, a sleeve pressing and testing station 35 with pressing stroke and testing stroke avoiding each other, an end cap loading pre-assembly station 36 with end cap concentricity guidance, an end cap pressing station 37, and a fifth housing transfer station 38. The third loading device includes at least one third bearing position, and the third bearing position includes a third housing loading groove 311 opposite to the direction of the second housing loading groove.

[0072] The insertion and extraction force detection and unloading device 4 includes a sixth housing transfer station 41, an insertion and extraction force detection station 42, and an unloading station 43.

[0073] A shell turnover mechanism 5 is provided between the first shell transfer station and the second shell transfer station, between the third shell transfer station and the fourth shell transfer station, between the fifth shell transfer station and the sixth shell transfer station, between the sixth shell transfer station and the insertion / extraction force detection station, and between the insertion / extraction force detection station and the unloading station for shell turnover.

[0074] Detailed implementation process and principle explanation:

[0075] Reference Figures 1 to 3 As shown, during the automated assembly of the energy storage plug, the assembly is carried out in the order of the first assembly device 1, the second assembly device 2, the third assembly device 3, and the insertion / extraction force detection and unloading device 4.

[0076] When assembling on the first assembly device 1, such as Figures 4 to 9 As shown, the housing 100 is loaded onto the first set of loading devices 11 on the housing loading station 13 by manual or automated equipment. At this time, the housing 100 is set horizontally, and its loading cavity faces outward radially. The housing 100 is confined in the first housing loading groove 111. The station is switched with the first rotating pallet 12. At the conductive pile loading station 14, the conductive pile 200 is picked up and placed in the conductive pile guide loading groove 112. After the high-precision positioning is completed, the conductive pile is pushed and assembled at the conductive pile pushing and assembly station 15. The nose end 2002 is forced into the housing 100 by horizontally pushing the pile tube end 2001 to achieve the assembly and connection of the two. After the connection is completed, it is moved to the first housing transfer station 16 to wait for turnover.

[0077] During assembly on the second assembly device 2, such as Figures 10 to 17 As shown, the housing turnover mechanism 5 picks up the assembled housing from the first housing transfer station 16 and loads it into the second housing loading slot 211 of the second housing transfer station 23. When the first rotating pallet 12 is transferred to the second rotating pallet 22, they are in adjacent positions, so the direction of the loading slot is reversed after the transfer, and its loading cavity is radially facing inward. As the second rotating pallet 22 rotates and the station switches, the sealing ring feeding and assembly station 24 performs the sealing ring fitting operation on the outer peripheral wall of the shaft tube end 1001. The button feeding and pushing assembly station 25 performs the automated feeding of the U-shaped button 300 and pushes it into the button slot 1002 to achieve assembly. After assembly, it is moved to the third housing transfer station 26 to wait for the third assembly device 3 to pick it up and transfer it.

[0078] When assembling on the third assembly device 3, such as Figures 18 to 24As shown, the housing transfer mechanism 5 picks up the assembled housing from the third housing transfer station 26 and transfers it to the fourth housing transfer station 33. As the third rotating tray 32 rotates, the sleeve is pre-assembled at the sleeve loading and pre-assembly station 34. During pre-assembly, the sleeve is pressed while ensuring concentricity. The assembly then rotates to the sleeve pressing and testing station 35 for pressing. After pressing, the pressing end retracts, and the testing end performs resistance testing on the sleeve. It should be noted that the pressing end generally uses a vertical stroke, while the displacement of the testing end needs to avoid the pressing stroke of the pressing end. At the end cap loading and pre-assembly station 36, the end caps are automatically loaded and pre-pressed to ensure concentricity. At the end cap pressing station 37, pressing and shaping are performed, at which point the product assembly is complete. The assembled product is then transferred to the fifth housing transfer station 38 for inspection and turnover.

[0079] When the insertion and extraction force detection unloading device 4 performs detection and unloading, such as Figure 25 and Figure 26 As shown, the workstation switching is achieved through one or more housing turnover mechanisms 5. First, the finished product on the fifth housing transfer station 38 is picked up and transferred to the sixth housing transfer station 41. At this time, the sixth housing transfer station 41 performs secondary positioning on the current finished product. After positioning, it is transferred to the insertion and extraction force detection station 42 for insertion and extraction force detection. This insertion and extraction force detection generally simulates the mating and separation between the socket and the plug. After the detection is completed, the finished product is screened and unloaded to the unloading station 43 according to the detection results. The unloading station 43 can use a conveyor belt or a receiving frame to receive and unload the finished product.

[0080] In one specific embodiment, such as Figures 4 to 9 As shown, the shell loading station 13 includes a shell loading mechanism 130, which includes a shell supply unit 131 and a shell automated transfer unit 132 for rotating between the shell supply unit 131 and the shell loading station.

[0081] The conductive pile loading station 14 includes a conductive pile loading mechanism 140, which includes a conductive pile supply unit 141, a conductive pile transfer pre-assembly unit 142 for picking up and transferring conductive piles for pre-assembly, and a conductive pile pre-assembly visual guidance unit 143 for visually guiding the conductive pile transfer pre-assembly unit.

[0082] The conductive pile pushing and assembly station 15 includes a pushing and assembly mechanism 150. The pushing and assembly mechanism 150 includes a conductive pile pushing part 151 with horizontal pushing displacement, which is arranged one-to-one with the conductive pile guide groove. The conductive pile pushing part 151 is provided with a positioning pin that is positioned and cooperates with the end of the pile pipe.

[0083] Specifically, the shell supply unit 131 can supply shell materials by means of manual feeding or automated turnover feeding. When using automated turnover feeding, it can be done by means of linear conveyor belt, conveyor rail, vibrating chamber and direct vibration, vibrating plate, etc. As long as the feeding mechanism and conveying method meet the requirements, they are all within the protection scope of this case.

[0084] During specific operations, the shell supply unit 131 supplies shells and loads them, while the shell automated transfer unit 132 picks up the shells and loads them onto the shell loading station.

[0085] When the conductive pile loading station 14 is in operation, the conductive pile supply unit 141 can use linear conveyor belts, conveyor rails, vibration chambers, direct vibration, vibratory feeders, etc. The conductive pile transfer pre-assembly unit 142 picks up the conductive piles and performs high-precision loading under the guidance of the conductive pile pre-assembly visual guidance unit 143.

[0086] When the conductive pile is pushed and assembled at station 15, the conductive pile pushing part 151 achieves precise alignment and fit through the positioning pin. Then, it uses its horizontal pushing displacement and guide groove to push the material in the precise assembly direction. The positioning pin generally adopts a guide structure with a conical end to meet the requirements of automated alignment and correction.

[0087] In one specific embodiment, the housing loading station 13 includes a housing position correction mechanism 133 located on the transfer path of the housing automated transfer unit and a correction visual inspection mechanism 134 facing the housing position correction mechanism. The housing position correction mechanism includes a correction carrier having at least one housing correction groove.

[0088] This satisfies the positional correction requirements for shell loading, ensuring accurate and reliable mounting position after shell loading and transfer.

[0089] In one specific embodiment, such as Figures 10 to 17 As shown, the second housing transfer station 23 includes a first housing transfer mechanism 51 having a turnover displacement between the first housing transfer station 16 and the second housing transfer station 23.

[0090] The sealing ring feeding and assembly station 24 includes a sealing ring feeding and assembly mechanism 240, which includes a sealing ring supply unit 241, a sealing ring receiving end 242 located at the discharge end of the sealing ring supply unit, and a transfer picking unit 243 for picking up the sealing rings on the sealing ring receiving end for transfer and assembly.

[0091] The button feeding and assembly station 25 includes a button feeding and assembly mechanism 251 and a button feeding mechanism 252 for feeding materials to the button feeding and assembly mechanism. The button feeding and assembly mechanism 251 includes a support assembly base 2511, a push guide groove 2512 disposed on the support assembly base and corresponding to the second support position, and a button pushing part 2513 disposed in the push guide groove and having a horizontal pushing stroke. The push end face of the button pushing part 2513 is provided with an arc-shaped groove.

[0092] The third housing transfer station 26 includes a second housing transfer mechanism 52 that has a transfer displacement between the third housing transfer station and the third assembly unit.

[0093] During actual operation, the first housing turnover mechanism 51 picks up the housing on the first housing transfer station 16 and transfers it to the second housing transfer station 23, as the pallet rotates and the station switches.

[0094] The sealing ring supply unit 241 supplies sealing rings, and all mechanisms that meet its supply requirements are within the protection scope of this case. The sealing rings are supplied at the sealing ring receiving end 242, and the transfer and picking unit 243 picks up the sealing rings and fits them onto the housing to achieve the fitting and assembly of the sealing rings.

[0095] The button feeding mechanism 252 supplies the buttons using a vibrating tray and visual guidance. Other supply transfer feeding mechanisms are also within the scope of protection of this invention. The buttons are placed on the push guide groove 2512. At this time, the button pushing part 2513 achieves cooperation and abutment through the arc groove and performs precise guidance and pushing of the material assembly along the push guide groove 2512.

[0096] After the assembly is picked up by the second housing turnover mechanism 52 at the third housing transfer station 26, it is transferred to the third assembly device.

[0097] In one specific embodiment, the transfer pickup unit 243 includes a plurality of radially displaced outer expansion bodies 2431 for embedding into the sealing ring, and a plurality of radially displaced and connected pushing bodies 2432 for pushing the sealing ring.

[0098] Specifically, when picking up the sealing ring, the sealing ring is radially expanded by the expansion body 2431. After the fitting operation is completed, the expansion body 2431 is retracted and released. At this time, the sealing ring is pushed by the pusher body 2432 to ensure that it is pushed in place, which meets the radial difference adaptation requirements of products of different specifications.

[0099] In one specific embodiment, such as Figures 18 to 24As shown, the sleeve feeding pre-assembly station 34 includes a sleeve concentricity maintaining mechanism 341 and a sleeve feeding pre-assembly mechanism 342; the sleeve pressing and testing station 35 includes a sleeve pressing mechanism 351 and a resistance testing mechanism 352 with pressing stroke avoidance; the end cap feeding pre-assembly station 36 includes an end cap concentricity maintaining mechanism 361 and an end cap feeding pre-assembly mechanism 362; and the end cap pressing station 37 includes an end cap pressing mechanism 370.

[0100] Specifically, during sleeve loading, the sleeve feeding and pre-assembly mechanism 342 performs sleeve supply, pickup, and turnover operations. The sleeve concentricity maintaining mechanism 341 provides axial guidance for the sleeve, thereby achieving the guided pre-compression stroke. The sleeve feeding and pre-assembly mechanism 342 generally includes conveying and feeding methods such as a vibratory feeder, vibratory chamber, conveyor belt, and conveyor track. It has a pickup end for picking up sleeves for assembly and pre-compression, and pre-compression assembly is performed under concentricity guidance.

[0101] The end cap feeding and pre-assembly station 36 is similar to the sleeve pre-assembly station. It uses the end cap feeding and pre-assembly mechanism 362 to supply, rotate, and pre-assemble materials. The supply method is not limited. The end cap concentricity keeping mechanism 361 is used to keep the axial direction.

[0102] It should be noted that at the sleeve pressing and testing station 35, after the sleeve is pressed into place by the sleeve pressing mechanism 351, it retracts. At this time, the pressing stroke of the resistance testing mechanism 352 avoids the pressing operation requirements. During the test, the pressing retraction provides its testing stroke space.

[0103] At end cap pressing station 37, pressing and assembly operations are performed by end cap pressing mechanism 370.

[0104] In one specific embodiment, the third assembly device 3 includes a fixed support tray 6 located on a third rotating tray for mounting the sleeve concentricity maintaining mechanism, the resistance detection mechanism, and the end cap concentricity maintaining mechanism.

[0105] The sleeve concentricity holding mechanism 341 includes a sleeve concentricity displacement carrier 3411 having radial linear displacement along a fixed bearing tray, and a sleeve concentricity clamp 3412 disposed on the sleeve concentricity displacement carrier for radially clamping the sleeve.

[0106] The sleeve concentricity fixture 3412 satisfies the sleeve guiding requirements and meets the adaptability requirements of products with different diameter specifications through opening and closing stroke control.

[0107] The resistance detection mechanism 352 includes a relief displacement carrier 3521 with tilting relief linear displacement, and a resistance contact detection end 3522 on the relief displacement carrier that corresponds one-to-one with the third housing groove.

[0108] The resistance contact detection terminal 3522 is mounted by the avoidance displacement carrier 3521, and the tilt displacement meets the avoidance and detection stroke requirements.

[0109] The end cap concentricity retention mechanism 361 includes an end cap concentricity displacement carrier 3611 having radial linear displacement along a fixed bearing tray, and an end cap concentricity clamp 3612 disposed on the end cap concentricity displacement carrier for radially clamping the end cap.

[0110] It meets the requirements of concentricity orientation and compatibility.

[0111] In one specific embodiment, such as Figure 25 and Figure 26 As shown, the sixth housing transfer station 41 includes a transfer carrier 411 with at least one transfer slot and a third housing transfer mechanism 53 for circumferential displacement between the fifth housing transfer station and the sixth housing transfer station. The insertion and extraction force detection station 42 includes a detection carrier 421 with at least one detection slot and a fourth housing transfer mechanism 54 for circumferential displacement between the sixth housing transfer station and the insertion and extraction force detection station. The unloading station 43 includes an unloading and receiving mechanism 431 and an unloading and transfer mechanism 55 for circumferential displacement between the insertion and extraction force detection station and the unloading and receiving mechanism.

[0112] Detailed implementation process description:

[0113] After the third housing turnover mechanism 53 picks up the housing, it is transferred to the transfer carrier 411 for positional correction. Then, the fourth housing turnover mechanism 54 picks it up and places it on the testing carrier 421. The top of the testing carrier 421 is equipped with a insertion and extraction force testing platform 422 with lifting displacement. It generally uses a socket testing end equipped with a pressure sensor that is compatible with the energy storage plug for testing. After the testing is completed, the unloading turnover mechanism 55 picks up the housing and transfers it for unloading. The unloading is carried out on the unloading receiving mechanism 431, which can be screened using a screening bin or a screening conveyor belt.

[0114] It should be noted that the fourth shell turnover mechanism 54 and the unloading turnover mechanism 55 can adopt a linkage drive structure to realize the linkage turnover requirements between multiple workstations. Of course, adopting a split type can facilitate the screening of materials.

[0115] In this case, the first to fourth shell turnover mechanisms and the unloading turnover mechanism 55 adopt a design of a mechanical arm carrying a shell picking mechanism. Of course, a linear displacement or lifting displacement mechanism can also be used to carry the shell picking mechanism. The picking mechanism can be a clamp, a negative pressure picking mechanism, etc. All mechanisms that meet the shell turnover requirements are within the protection scope of this case.

[0116] In one specific embodiment, the first set of loading devices includes two first bearing positions with different specifications, the second set of loading devices includes second bearing positions that correspond one-to-one with the first bearing positions, the third set of loading devices includes third bearing positions that correspond one-to-one with the first bearing positions, the transfer device includes transfer slots that correspond one-to-one with the first bearing positions, and the detection device includes detection slots that correspond one-to-one with the first bearing positions.

[0117] This means that the system meets the compatibility assembly requirements of two energy storage plugs with different specifications. The main differences in specifications are the diameter of the shaft tube end and the pile tube end, as well as the horizontal dimensional differences in the assembly of the shell and the conductive pile. The fully automated pressing and assembly equipment in this project meets the assembly and operation requirements of two products with different specifications and sizes.

[0118] In one specific embodiment, such as Figures 1 to 3 As shown, the first assembly device 1, the second assembly device 2, and the insertion / extraction force detection and unloading device 4 are arranged adjacent to each other, and the third assembly device 3 is arranged adjacent to the second assembly device 2 and the insertion / extraction force detection and unloading device 4. The overall layout is compact, meeting the requirements for automated operation of the U-shaped rotary system.

[0119] The above description demonstrates that the system meets the requirements for fully automated assembly of energy storage plugs, ensuring smooth, efficient, and stable online operation and eliminating frequent downtime. It employs an innovative design combining multiple rotating workstations with distributed processes, improving assembly accuracy at each station while ensuring smooth turnover. The sequential reversal of the housing transfer achieves adaptability at each crimping station, satisfying the spatial layout for crimping and guiding. The coordinated and stable turnover of each station significantly improves the product assembly qualification rate. The overall design features a U-shaped rotating layout with a compact spatial arrangement.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
