Description

Technical Field

[0001] This invention relates to the field of socket assembly technology, specifically to an automated assembly process and production line for British-style sockets. Background Technology

[0002] British-style sockets are widely used in countries and regions such as the United Kingdom, Nigeria, Tanzania, India, Pakistan, Malaysia, Singapore, and Hong Kong.

[0003] Currently, the assembly and production of British-style sockets generally adopts manual assembly line operations. Moreover, conventional British-style socket products do not have end cap structures. In the traditional process, operators first weld the neutral, live, and ground wires of the power cord to the corresponding conductive copper busbars to form a power cord-copper busbar assembly. Then, this assembly is installed and fixed inside the base. Next, the indicator light (neon bulb or LED) is directly welded to the corresponding conductive copper busbar to realize the power-on indication function. Finally, the top cover is put on and fixed with screws to complete the assembly of the entire socket. Since conventional British-style sockets do not have end caps, the entire welding area and the connection point between the power cord and the copper busbar are exposed inside the base, and are only covered by the top cover.

[0004] This end-capless structural design, along with the process sequence of first soldering the power cord to the copper busbar, then installing the copper busbar into the base, and finally soldering the indicator light, leads to numerous drawbacks in the entire assembly process: Firstly, after the power cord is soldered to the conductive copper busbar, a long power cable is connected to the copper busbar. The component has an irregular shape, which makes it extremely inconvenient to operate and difficult to position when it is subsequently installed into the base. Secondly, due to the lack of end cap structure, the welding area of ​​the copper busbar is located deep inside the base after it is installed in the base. When welding the power cord and indicator light while it is installed in the base, the welding space is extremely small. Operators need to perform fine welding inside the shell, which is difficult to operate. Moreover, high-temperature welding operations can easily burn the shell, resulting in appearance defects or safety hazards. Third, the welding process is extensive and scattered throughout the entire process (three welding points for the power cord, one or more welding points for the indicator light), requiring a large amount of manual labor for each socket, resulting in a slow production cycle and severely limited capacity. Fourth, welding quality is highly dependent on the skill level and stability of the operators. Defects such as incomplete welding and missing welding are difficult to control effectively, resulting in a high product defect rate.

[0005] Fifth, soldering indicator lights require a large amount of solder and flux, which leads to a significant increase in production costs.

[0006] In addition, all welding and assembly operations must be completed within the single housing of the base, resulting in mutual constraints between processes and insufficient operating space. The entire assembly process is highly dependent on manual operation, making it difficult to achieve continuous automatic assembly throughout the entire process through automated equipment. Summary of the Invention

[0007] To address the technical problems existing in the background art, the present invention proposes an automatic assembly process and production line for British-style sockets.

[0008] The technical solution adopted by this invention to solve its technical problem is as follows: An automated assembly process for British-style sockets includes the following steps: S0, Base loading: The bases are stacked in the base storage module. The base storage module transports the bases to the loading position and then transfers the bases from the loading position to the conveying fixture of the assembly conveyor line through the base transfer module. S1. Conductive strip installation: The assembly conveyor line moves the conveyor fixture carrying the base to the conductive strip installation station, stacks the trays containing the conductive strips on the tray loading module, and the base is provided with positioning slots for inserting the conductive strips. The tray loading module moves the trays carrying the conductive strips to the loading position, and takes out the conductive strips from the trays and inserts them into the positioning slots of the base through the conductive strip installation component. S2. PCB Light Board Installation: After the conductive strip is installed, the assembly conveyor line moves the conveyor fixture of the support base to the PCB light board installation station, places the whole board on the PCB light board splitting module, the PCB light board splitting module divides the whole board into multiple single PCB light boards, and inserts the PCB light boards into the conductive strip through the PCB light board transfer module, so that the PCB light board and the conductive strip form an electrical connection. S3. Top Cover Installation: After the PCB light board installation is completed, the assembly conveyor line moves the conveyor fixture carrying the base to the top cover installation station, stacks the top covers in the top cover storage module, the top cover storage module conveys the top covers to the loading position, and installs the top covers onto the base through the top cover transfer module. S4. Power cord installation: After the top cover is installed, the assembly conveyor line moves the conveyor fixture carrying the base to the power cord installation station. The base is equipped with a wire clamping groove. The neutral wire, live wire, and ground wire of the power cord are clamped into the wire clamping groove of the base by manual means or by the power cord installation module, so that the three wires are respectively set adjacent to the corresponding conductive strip. S5. Welding: After the power cord is installed, the assembly conveyor line moves the conveyor fixture of the support base to the welding station. The welding device welds the ends of the neutral wire, live wire and ground wire of the power cord to the corresponding conductive strips respectively, so that the power cord and the conductive strips form an electrical connection. S6. End cap installation: After welding is completed, the assembly conveyor line moves the conveyor fixture carrying the base to the end cap installation station. The end cap storage module transports the end cap to the loading position. The end cap transfer module picks up the end cap and installs it to the rear end of the base, so that the end cap covers the welding area of ​​the power line and the conductive strip. S7. Screw Locking: After the end cap is installed, the assembly conveyor line moves the conveyor fixture carrying the base to the screw locking station. The automatic screw locking mechanism screws into the corresponding screw holes of the end cap and the top cover in sequence, locking the end cap and the top cover onto the base respectively. S8. Unloading: After the screws are locked, the assembly conveyor line moves the conveyor fixture carrying the base to the unloading station. The unloading transfer module transfers the assembled socket to the unloading conveyor line for automatic unloading.

[0009] Preferably, the conductive strip includes an L-pole conductive strip, an N-pole conductive strip, and a ground conductive strip. The PCB lamp board is inserted into the L-pole and N-pole conductive strips. Through the above improvements, by subdividing the installation of the conductive strips into the sequential installation of the L-pole, N-pole, and ground conductive strips, and utilizing the PCB lamp board to simultaneously insert into the L-pole and N-pole conductive strips, on the one hand, orderly and automatic assembly of the conductive strips is achieved, avoiding mutual interference and ensuring accurate positioning; on the other hand, the PCB lamp board and the three conductive strips are electrically connected in one go through the insertion, replacing the traditional multiple manual soldering, significantly improving assembly efficiency and connection reliability. Moreover, the insertion method ensures the consistency of electrical clearance and creepage distance, fully adapting to the needs of automated production.

[0010] Preferably, a visual inspection step is included between step S2 and step S3: the connection area between the PCB light board and the conductive strip is inspected by a visual inspection component to determine the assembly quality. Through the above improvements, online quality inspection of the connection area between the PCB light board and the conductive strip is performed after the PCB light board is installed and before the top cover is installed. This can promptly detect assembly defects such as poor insertion, misalignment, and inadequate contact, preventing defective products from flowing into subsequent workstations and causing rework or scrap. This reduces production losses and effectively improves product yield and process stability through closed-loop quality control, fully meeting the quality control requirements of automated production lines.

[0011] An automated assembly production line for British-style sockets using an assembly process includes a machine base, an assembly conveyor line on the machine base, and a conveying fixture that slides cyclically along the assembly conveyor line on the assembly conveyor line. The conveying fixture is provided with a placement groove for placing a base. The machine platform is sequentially equipped with a base loading assembly, a conductive strip mounting assembly, a PCB light board mounting assembly, a top cover mounting assembly, and a unloading assembly along the conveying direction of the conveying fixture. The base loading assembly includes a base storage module for storing bases and a base transfer module for transferring bases from the output end of the base storage module to the conveying fixture. The base transfer module includes a base transfer bracket, a first suction plate spaced on the base transfer bracket, a first linear lifting unit for driving the base transfer bracket to move up and down, and a first reciprocating lateral transfer unit for driving the base transfer bracket to reciprocate between the base storage module and the assembly conveyor line. The conductive strip mounting assembly includes a first mounting structure for mounting an L-pole conductive strip, a second mounting structure for mounting an N-pole conductive strip, and a third mounting structure for mounting a ground wire conductive strip. The first, second, and third mounting structures are spaced apart along the conveying direction of the conveying fixture. The first, second, and third mounting structures include a pallet loading module for placing the conductive strip and a conductive strip transfer module for inserting the conductive strip onto the base. The conductive strip transfer module includes a mounting bracket, gripper cylinders spaced apart on the mounting bracket, a second linear lifting unit for driving the mounting bracket to move up and down, and a second reciprocating lateral movement unit for driving the mounting bracket to reciprocate between the pallet loading module and the assembly conveyor line. The PCB lamp board mounting assembly includes a PCB lamp board splitting module for splitting the entire board, and a PCB lamp board transfer module for inserting the split PCB lamp boards onto conductive strips. The PCB lamp board splitting module includes a splitting and cutting structure for splitting the entire board, and a transfer and flipping structure for transferring and flipping the PCB lamp boards. The PCB lamp board transfer module includes a transfer bracket, a clamping cylinder mounted on the transfer bracket, a third linear lifting unit for driving the transfer bracket to move up and down, and a third reciprocating lateral movement unit for driving the transfer bracket to reciprocate between the PCB lamp board splitting module and the assembly conveyor line. The cover mounting assembly includes a cover storage module for storing the cover, and a cover transfer module for transferring the cover from the output end of the cover storage module to the base. The cover transfer module includes a cover transfer bracket, a second suction plate spaced on the cover transfer bracket, a fourth linear lifting unit for driving the cover transfer bracket to move up and down, and a fourth reciprocating lateral movement unit for driving the cover transfer bracket to reciprocate between the cover storage module and the assembly conveyor line. The unloading assembly includes an unloading conveyor line and an unloading transfer module for transferring the socket from the conveyor fixture to the unloading conveyor line. Through the above improvements, by assembling the conveyor line in series with the base loading assembly, conductive strip mounting assembly, PCB light board mounting assembly, top cover mounting assembly and unloading assembly, the fully automated continuous assembly of the British socket is realized. This effectively solves the problems of scattered equipment and low efficiency of manual transfer in traditional single-process equipment. Furthermore, the conductive strip and PCB light board are electrically connected by plug-in connection, eliminating the need for welding and avoiding quality risks such as poor soldering and missing soldering. At the same time, it simplifies the assembly process and is more conducive to high-speed automated production.

[0012] Preferably, the base storage module includes a base loading seat, a base loading frame slidably disposed on the base loading seat, a first sliding unit for driving the base loading frame to slide, and a base conveyor line for connecting the discharge end of the base loading frame; the base loading frame is provided with a plurality of base discharge slots, the bottom of the base discharge slots is provided with a first discharge port for base discharge, and the base loading seat is provided with a first pushing unit for pushing the bases from the first discharge port to the base conveyor line; the base loading seat is provided with a baffle plate, and the first discharge port is connected to the base loading frame. When the base conveyor lines are arranged opposite each other, the baffle plate blocks the other first discharge ports. Through the above improvements, multiple base feeding troughs can achieve continuous feeding without stopping the machine. When the bases in one feeding trough are used up, the first sliding unit drives the base loading frame to slide and switch to the next feeding trough opposite the base conveyor line, without stopping the machine to replenish the material, which effectively improves the continuity of feeding. At the same time, when a certain discharge port is aligned with the conveyor line, the baffle plate blocks other discharge ports, ensuring that the bases are discharged in an orderly manner, avoiding misalignment or simultaneous discharge, simplifying the feeding control logic, and improving the feeding stability and automation level.

[0013] Preferably, the pallet loading module includes a first pallet support for placing full pallets, a second pallet support for placing empty pallets, and a pallet conveying structure for transporting pallets. The first pallet support is provided with a supporting cylinder for supporting the pallet, and the actuating end of the supporting cylinder supports the bottom of the pallet. The second pallet support is provided with a supporting block, which supports the bottom of the pallet. The second pallet support is also provided with an anti-rotation seat, and the supporting block is mounted on the anti-rotation seat, which restricts the supporting block from rotating away from the pallet. The pallet conveying structure includes a support plate for supporting the pallet, a lifting unit for driving the support plate to move up and down, and a sliding structure for driving the support plate to move along the arrangement direction of the first pallet support and the second pallet support. The support plate is equipped with an abutment fixing unit, the abutment fixing unit's moving end of which is equipped with an abutment fixing plate for fixing the pallet. Through these improvements, the first pallet support and the second pallet support respectively store full pallets and empty pallets, and together with the pallet conveying structure, achieve automatic pallet transfer and stacking, realizing automatic pallet feeding and empty pallet recovery. This eliminates the need for frequent manual pallet replacement, improving the continuity of material supply. The support cylinder and support block reliably support the pallet at the material picking and recovery positions, respectively. The anti-rotation seat prevents the support block from rotating in the opposite direction, avoiding accidental pallet falls and ensuring stability and safety during pallet switching. The abutment fixing unit fixes the pallet by the abutment fixing plate when the support plate moves, ensuring that the pallet does not shift during conveying, improving the accuracy of the conductive strip's material picking position, and further ensuring the stable operation of automated assembly.

[0014] Preferably, the plate-splitting and cutting structure includes a whole plate conveying bracket, a clamping and moving mechanism that drives the whole plate to move along the whole plate conveying bracket, a cutting unit mounted above the whole plate conveying bracket, and a traversing mechanism that drives the cutting unit to move. The clamping and moving mechanism is used to clamp the whole plate and drive the whole plate to move stepwise along the whole plate conveying bracket, and the traversing mechanism drives the cutting unit to move horizontally to cut the whole plate into plates. The whole plate conveying support is also provided with a whole plate unloading structure. The whole plate unloading structure includes abutting control units for abutting both sides of the whole plate. The abutting control units selectively release or clamp the whole plate through opening or closing actions to control the whole plate to fall onto the whole plate conveying support. The transfer and flipping structure includes a loading plate, a transfer mechanism, and a flipping mechanism. The transfer mechanism moves the cut PCB light board from the output end of the board cutting structure to the loading base. The flipping mechanism flips the PCB light board placed on the loading base from a horizontal position to a vertical position. Through these improvements, the clamping and moving mechanism drives the entire board to move stepwise, and in conjunction with the lateral movement mechanism, drives the cutting unit to cut horizontally, realizing automatic and precise board separation, replacing manual board breaking or cutting, improving board separation efficiency and consistency. The abutment control unit controls the orderly falling of the entire board onto the conveyor bracket through opening and closing actions, avoiding board stacking or jamming, and ensuring continuous and stable material supply. The transfer mechanism moves the cut PCB light board to the flipping mechanism, which turns it from a horizontal position to a vertical position, facilitating subsequent insertion onto the conductive strip, simplifying the picking and positioning difficulty, and further improving the smoothness of automated assembly.

[0015] Preferably, the upper cover storage module includes an upper cover feeding seat, an upper cover feeding frame slidably disposed on the upper cover feeding seat, a second sliding unit for driving the upper cover feeding frame to slide, and an upper cover conveyor line for connecting the upper cover feeding frame to the discharge end; The upper cover feeding frame is provided with several upper cover feeding slots. The bottom of the upper cover feeding slots is provided with a second discharge port for the upper cover to be discharged. The upper covers are vertically stacked in the upper cover feeding slots, and the upper cover feeding seat is provided with a second pushing unit. The second pushing unit pushes the upper covers from the second discharge port to the upper cover conveyor line, and drives the upper covers to flip from a vertical posture to a horizontal posture during the pushing process. Through the above improvements, the upper covers are stored in the upper cover feeding slots in a vertical stacked manner. The diameter of the second discharge port is smaller than the width of the upper covers in the vertical state, so that the vertically stacked upper covers cannot fall directly from the second discharge port. Only when the second pushing unit pushes out the bottom upper cover, the upper cover is forced to flip from a vertical posture to a horizontal posture under the limitation of the discharge port diameter in order to pass through. This realizes the integrated action of discharging and flipping at the same time, without the need to set up an additional independent flipping mechanism or add a material blocking device. The module structure is compact and simple, reducing the equipment manufacturing cost.

[0016] Preferably, a visual inspection component is provided between the PCB light board mounting assembly and the top cover mounting assembly. The visual inspection component includes an inspection bracket and an inspection camera mounted on the inspection bracket. The inspection camera is positioned facing the connection area between the PCB light board and the conductive strip. Through the above improvements, the camera lens is directly facing the connection area between the PCB light board and the conductive strip, realizing online and accurate imaging inspection of the insertion status. This enables timely identification of defects such as misaligned insertion and incomplete contact before the product enters the next process, avoiding defective products from flowing into subsequent assembly processes and causing rework waste. This effectively reduces production losses and improves product yield and production line quality control.

[0017] Preferably, the unloading conveyor line includes a first unloading line for conveying qualified products and a second unloading line for conveying unqualified products. The unloading transfer module includes an unloading seat, an unloading suction cup mounted on the unloading seat, and an unloading moving module for driving the unloading seat to move. Through the above improvements, the first and second unloading lines respectively convey qualified and unqualified products. With the help of the unloading moving module driving the suction cup, the assembled sockets are transferred to the corresponding conveyor line according to the test results. This realizes automatic sorting and unloading of finished products, avoids mixing of qualified and unqualified products, and simplifies the subsequent manual sorting process.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects: By optimizing and improving the structure of the British-style socket, adding end caps, and introducing PCB light boards to replace traditional indicator lights, a fully automated assembly process was designed. This process arranges the processes of conductive strip insertion, PCB light board snap-fit, power cord installation, welding, end cap installation, and screw tightening sequentially along the assembly conveyor line, with each station operating in parallel. This eliminates the drawbacks of overlapping processes and repeated turnover in traditional processes, achieving continuous assembly line-style automated assembly, significantly improving production cycle time and assembly efficiency. The welding process is arranged before the end cap installation, with the welding area completely open, facilitating precise welding of the connection between the power cord and the conductive strip by the welding device. This avoids the problem of easily burning the shell due to the narrow welding space in traditional processes, effectively reducing defects such as cold solder joints and missing solder joints, improving product quality and yield. The direct insertion and snap-fit ​​of the PCB light board and conductive strip achieves electrical connection, replacing the cumbersome process of traditional manual welding of indicator lights. This simplifies the assembly process, makes the process suitable for automated equipment, and saves solder and flux, reducing production costs. Attached Figure Description

[0020] 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, and 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.

[0021] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0022] like Figure 1 , Figure 19 , Figure 20 As shown, an automated assembly process for British-style sockets includes the following steps: S0, Base 10 loading: The base 10 is stacked in the base storage module 101. The base storage module 101 transports the base 10 to the loading position and the base transfer module 102 transfers the base 10 from the loading position to the conveying fixture 3 of the assembly conveyor line 2. S1. Installation of conductive strip 11: The assembly conveyor line 2 moves the conveyor fixture 3 carrying the base 10 to the conductive strip installation station, stacks the trays containing the conductive strip 11 on the tray loading module 204, the base 10 is provided with positioning slots for the conductive strip 11 to be inserted, the tray loading module 204 moves the trays carrying the conductive strip 11 to the loading position, and takes out the conductive strip 11 from the tray and inserts it into the positioning slots of the base 10 through the conductive strip installation component 6. S2, PCB lamp board 13 installation: After the conductive strip 11 is installed, the assembly conveyor line 2 moves the conveyor fixture 3 of the support base 10 to the PCB lamp board installation station, places the whole board on the PCB lamp board splitting module 301, the PCB lamp board splitting module 301 divides the whole board into multiple single PCB lamp boards 13, and inserts the PCB lamp boards 13 into the conductive strip 11 through the PCB lamp board transfer module 302, so that the PCB lamp board 13 and the conductive strip 11 form an electrical connection. S3, Installation of top cover 12: After the PCB lamp board 13 is installed, the assembly conveyor line 2 moves the conveyor fixture 3 carrying the base 10 to the top cover installation station, stacks the top cover 12 in the top cover storage module 401, the top cover storage module 401 conveys the top cover 12 to the loading position, and installs the top cover 12 onto the base 10 through the top cover transfer module 402. S4. Power cord installation: After the top cover 12 is installed, the assembly conveyor line 2 moves the conveyor fixture 3 carrying the base 10 to the power cord installation station. The base 10 is provided with a wire clamping groove. The neutral wire, live wire and ground wire of the power cord are clamped into the wire clamping groove of the base 10 by manual means or by the power cord installation module, so that the three wires are respectively set adjacent to the corresponding conductive strip 11. S5. Welding: After the power cord is installed, the assembly conveyor line 2 moves the conveyor fixture 3 of the support base 10 to the welding station. The welding device welds the ends of the neutral wire, live wire and ground wire of the power cord to the corresponding conductive strip 11 respectively, so that the power cord and the conductive strip 11 form an electrical connection. S6. End cap 14 installation: After welding is completed, the assembly conveyor line 2 moves the conveyor fixture 3 of the base 10 to the end cap installation station. The end cap storage module conveys the end cap 14 to the loading position. The end cap transfer module picks up the end cap 14 and installs it to the rear end of the base 10, so that the end cap 14 covers the welding area between the power line and the conductive strip 11. S7. Screw Locking: After the end cover 14 is installed, the assembly conveyor line 2 moves the conveyor fixture 3 carrying the base 10 to the screw locking station. The automatic screw locking mechanism screws into the corresponding screw holes of the end cover 14 and the upper cover 12 in sequence, locking the end cover 14 and the upper cover 12 onto the base 10 respectively. S8. Unloading: After the screws are locked, the assembly conveyor line 2 moves the conveyor fixture 3 of the support base 10 to the unloading station. The unloading transfer module 502 transfers the assembled socket to the unloading conveyor line 501 for automatic unloading.

[0023] By optimizing and improving the structure of the British socket, adding an end cover 14 and introducing a PCB light board 13 to replace the traditional indicator light, a fully automated assembly process was designed. This process arranges the processes of inserting the conductive strip 11, snapping the PCB light board 13, installing the power cord, welding, installing the end cover 14 and tightening screws along the assembly conveyor line 2. Each station operates in parallel, eliminating the drawbacks of process overlap and repeated turnover in the traditional process, realizing continuous assembly line automatic assembly, and significantly improving production cycle and assembly efficiency.

[0024] Meanwhile, the welding process is arranged before the end cap 14 is installed. The welding area is completely open, which makes it easy for the welding device to accurately weld the connection between the power line and the conductive strip 11. This avoids the problem of the shell being easily burned due to the narrow welding space in the traditional process, effectively reducing defects such as false welding and missing welding, and improving product quality and yield.

[0025] In addition, the PCB light board 13 and the conductive strip 11 are directly inserted and snapped together to achieve electrical connection, which replaces the cumbersome process of traditional manual soldering of indicator lights. This simplifies the assembly process, makes the process suitable for automated equipment, and saves solder and flux, thereby reducing production costs.

[0026] Specifically, the conductive strip 11 includes an L-pole conductive strip, an N-pole conductive strip, and a ground conductive strip. The PCB lamp board 13 is inserted into the L-pole and N-pole conductive strips. By subdividing the installation of the conductive strip 11 into the sequential installation of the L-pole, N-pole, and ground conductive strips, and utilizing the PCB lamp board 13 to simultaneously insert into the L-pole and N-pole conductive strips, on the one hand, the orderly automatic assembly of the conductive strips is achieved, avoiding mutual interference and ensuring accurate positioning; on the other hand, the PCB lamp board 13 and the three conductive strips are electrically connected in one go through the insertion, replacing the traditional multiple manual soldering, significantly improving assembly efficiency and connection reliability. Moreover, the insertion method ensures the consistency of electrical clearance and creepage distance, fully adapting to the needs of automated production.

[0027] In addition, a visual inspection step is included between step S2 and step S3: the connection area between the PCB light board 13 and the conductive strip 11 is inspected by the visual inspection component 601 to determine the assembly quality. After the PCB light board 13 is installed and before the top cover 12 is installed, the connection area between the PCB light board 13 and the conductive strip 11 is inspected online. This can promptly detect assembly defects such as poor insertion, misalignment, and incomplete contact, and prevent defective products from flowing into subsequent workstations and causing rework or scrap. This not only reduces production losses, but also effectively improves product yield and process stability through closed-loop quality control, fully meeting the quality control requirements of automated production lines.

[0028] like Figures 1 to 18 As shown, as a further explanation of the specific structure of the automatic assembly production line for British sockets, an automatic assembly production line for British sockets includes a machine base 1, an assembly conveyor line 2 is provided on the machine base 1, and a conveying fixture 3 is provided on the assembly conveyor line 2 to slide cyclically along the assembly conveyor line 2. The conveying fixture 3 is provided with a placement groove 4 for placing the base 10.

[0029] Specifically, the machine tool 1 is provided with a base loading assembly 5, a conductive strip mounting assembly 6, a PCB lamp board mounting assembly 7, a top cover mounting assembly 8, and a unloading assembly 9 in sequence along the conveying direction of the conveying fixture 3. The base loading assembly 5 includes a base storage module 101 for storing bases 10, and a base transfer module 102 for transferring bases 10 from the output end of the base storage module 101 to the conveying fixture 3. The base transfer module 102 includes a base transfer bracket 103, a first suction plate 104 spaced on the base transfer bracket 103, a first linear lifting unit 105 for driving the base transfer bracket 103 to move up and down, and a first reciprocating lateral movement unit 106 for driving the base transfer bracket 103 to reciprocate between the base storage module 101 and the assembly conveying line 2.

[0030] The conductive strip mounting assembly 6 includes a first mounting structure 201 for mounting the L-pole conductive strip, a second mounting structure 202 for mounting the N-pole conductive strip, and a third mounting structure 203 for mounting the ground wire conductive strip. The first mounting structure 201, the second mounting structure 202, and the third mounting structure 203 are spaced apart along the conveying direction of the conveying fixture 3. The first mounting structure 201, the second mounting structure 202, and the third mounting structure 203 include a pallet loading module 204 for placing the conductive strip 11 and a conductive strip transfer module 205 for inserting the conductive strip 11 onto the base 10. The conductive strip transfer module 205 includes a mounting bracket 206, a gripper cylinder 207 spaced apart on the mounting bracket 206, a second linear lifting unit 208 for driving the mounting bracket 206 to move up and down, and a second reciprocating lateral movement unit 209 for driving the mounting bracket 206 to reciprocate between the pallet loading module 204 and the assembly conveyor line 2.

[0031] The PCB lamp board mounting assembly 7 includes a PCB lamp board splitting module 301 for splitting the entire board, and a PCB lamp board transfer module 302 for inserting the split PCB lamp board 13 into the conductive strip 11. The PCB lamp board splitting module 301 includes a splitting cutting structure 303 for splitting the entire board, and a transfer and flipping structure 304 for transferring and flipping the PCB lamp board 13. The PCB lamp board transfer module 302 includes a transfer bracket 305, a clamping cylinder 306 disposed on the transfer bracket 305, a third linear lifting unit 307 for driving the transfer bracket 305 to move up and down, and a third reciprocating lateral movement unit 308 for driving the transfer bracket 305 to reciprocate between the PCB lamp board splitting module 301 and the assembly conveyor line 2. The cover mounting assembly 8 includes a cover storage module 401 for storing the cover 12, and a cover transfer module 402 for transferring the cover 12 from the output end of the cover storage module 401 to the base 10. The cover transfer module 402 includes a cover transfer bracket 403, a second suction plate 404 spaced on the cover transfer bracket 403, a fourth linear lifting unit 405 for driving the cover transfer bracket 403 to move up and down, and a fourth reciprocating transverse transfer unit 406 for driving the cover transfer bracket 403 to reciprocate between the cover storage module 401 and the assembly conveyor line 2. The unloading assembly 9 includes an unloading conveyor line 501 and an unloading transfer module 502 for transferring the socket from the conveying fixture 3 to the unloading conveyor line 501.

[0032] During the assembly process, the assembly conveyor line 2 on machine 1 serves as the carrier, and the conveyor fixture 3 flows sequentially along the circulating sliding path. First, the base transfer module 102 of the base loading assembly 5 picks up the base 10 from the base storage module 101 through the first suction plate 104. After lifting and lateral movement, it is accurately placed into the placement slot 4 of the conveyor fixture 3. Subsequently, the fixture passes sequentially through the first mounting structure 201, the second mounting structure 202, and the third mounting structure 203 of the conductive strip mounting assembly 6. Each structure is fed by the tray loading module 204, and the gripper cylinder 207, in conjunction with the second linear lifting unit 208 and the second reciprocating lateral movement unit 209, vertically presses the L pole, N pole, and ground conductive strip into the corresponding slots of the base 10. Then, the PCB lamp board mounting assembly 7 is first divided into whole boards by the board cutting structure 303 and then transferred and flipped by the transfer and flipping structure. 304 flips the lamp board to the correct orientation, and then the clamping cylinder 306 of the PCB lamp board transfer module 302 precisely inserts the lamp board onto the installed conductive strip 11 via the third linear lifting unit 307 and the third reciprocating lateral movement unit 308 to complete the electrical connection. Then, the upper cover transfer module 402 of the upper cover mounting assembly 8 uses the second suction plate 404 to pick up the upper cover 12 from the upper cover storage module 401, and moves the upper cover 12 to the base 10 and presses it to fasten it through the fourth linear lifting unit 405 and the fourth reciprocating lateral movement unit 406 to complete the outer shell encapsulation. Finally, the unloading and transfer module 502 of the unloading assembly 9 takes the finished socket out from the conveying fixture 3 and sends it to the unloading conveyor line 501 for output. The empty conveying fixture 3 continues to circulate back to the base loading station along the assembly conveyor line 2 to enter the next round of assembly cycle.

[0033] By assembling the conveyor line 2 in series with the base loading assembly 5, the conductive strip mounting assembly 6, the PCB lamp board mounting assembly 7, the top cover mounting assembly 8, and the unloading assembly 9, the entire process of British socket assembly is automated and continuous. This effectively solves the problems of scattered equipment and low efficiency of manual transfer in traditional single-process assembly. Furthermore, the conductive strip 11 and the PCB lamp board 13 are electrically connected by a plug-in method, eliminating the need for welding and avoiding quality problems such as poor soldering and missing soldering. At the same time, it simplifies the assembly process and is more conducive to high-speed automated production.

[0034] In addition, a power cord installation station, a power cord welding station, and an end cap installation station can be added to the top cover mounting component 8 to achieve fully automated production and significantly improve production efficiency.

[0035] like Figure 3 As shown, as a further explanation of the specific structure of the base storage module 101, the base storage module 101 includes a base loading seat 111, a base loading frame 112 slidably disposed on the base loading seat 111, a first sliding unit 113 for driving the base loading frame 112 to slide, and a base conveying line 114 for connecting the discharge end of the base loading frame 112. The base loading frame 112 is provided with a plurality of base discharge slots 115. The bottom of the base discharge slots 115 is provided with a first discharge port 116 for the base 10 to be discharged. The base loading seat 111 is provided with a first pushing unit 117 for pushing the base 10 from the first discharge port 116 to the base conveying line 114. The base loading seat 111 is provided with a baffle plate 118. When one first discharge port 116 is arranged opposite to the base conveying line 114, the baffle plate 118 blocks the other first discharge ports 116.

[0036] During the assembly process, multiple base feeding slots 115 achieve continuous material supply without stopping the machine. When the base 10 in one feeding slot is used up, the first sliding unit 113 drives the base loading frame 112 to slide and switch to the next feeding slot opposite the base conveyor line 114. There is no need to stop the machine to replenish the material, which effectively improves the continuity of material supply.

[0037] Meanwhile, when a certain discharge port is aligned with the conveyor line, the baffle plate 118 blocks other discharge ports, ensuring that the base 10 is discharged in an orderly manner, avoiding misalignment or simultaneous discharge, simplifying the feeding control logic, and improving the feeding stability and automation level.

[0038] like Figure 4 , Figure 5 As shown, further explanation of the specific structure of the pallet loading module 204 is provided. The pallet loading module 204 includes a first pallet support 211 for placing full pallets, a second pallet support 212 for placing empty pallets, and a pallet conveying structure 213 for transporting pallets.

[0039] Specifically, the first pallet support 211 is equipped with a support cylinder 214 for supporting the pallet, and the actuating end of the support cylinder 214 supports the bottom of the pallet. The second pallet support 212 is equipped with a support block 215, which supports the bottom of the pallet. The second pallet support 212 is also equipped with an anti-rotation seat 216, on which the support block 215 is mounted. The anti-rotation seat 216 restricts the support block 215 from rotating away from the pallet. The support cylinder 214 and the support block 215 reliably support the pallet at the material picking and recycling positions, respectively. The anti-rotation seat 216 prevents the support block 215 from rotating in the opposite direction, avoiding accidental pallet falls and ensuring stability and safety during pallet switching.

[0040] Furthermore, the pallet conveying structure 213 includes a support plate 217 for supporting the pallet, a lifting unit 218 for driving the support plate 217 to move up and down, and a sliding structure 219 for driving the support plate 217 to move along the arrangement direction of the first pallet support 211 and the second pallet support 212. The support plate 217 is provided with an abutting and fixing unit 220, and the abutting and fixing unit 220 is provided with an abutting and fixing plate 221 for fixing the pallet at its actuating end. The first pallet support 211 and the second pallet support 212 respectively store full pallets and empty pallets, and cooperate with the pallet conveying structure 213 to realize the automatic transfer and stacking of pallets, realize the automatic feeding of pallets and the recycling of empty pallets, eliminate the need for frequent manual pallet replacement, improve the continuity of material supply, and fix the pallet by fixing the support plate 221 when the support plate 217 moves, ensuring that the pallet does not shift during the conveying process, improving the accuracy of the material picking position of the conductive strip 11, and further ensuring the stable operation of automated assembly.

[0041] like Figure 6 , Figure 7 , Figure 8 As shown, a further explanation of the specific implementation of the plate-splitting cutting structure 303 and the transfer and flipping structure 304 is provided. The plate-splitting cutting structure 303 includes a whole plate conveying bracket 311, a clamping and moving mechanism 312 that drives the whole plate to move along the whole plate conveying bracket 311, a cutting unit 313 mounted above the whole plate conveying bracket 311, and a transverse moving mechanism 314 that drives the cutting unit 313 to move. The clamping and moving mechanism 312 is used to clamp the whole plate and drive the whole plate to move stepwise along the whole plate conveying bracket 311. The clamping and moving mechanism 312 includes a clamping unit and a linear transverse moving unit that drives the clamping unit to move. The transverse moving mechanism 314 drives the cutting unit 313 to move horizontally to cut the whole plate into plates.

[0042] In addition, the whole plate conveying support 311 is also provided with a whole plate unloading structure 315. The whole plate unloading structure 315 includes an abutment control unit 316 for abutting the two sides of the whole plate. The abutment control unit 316 selectively releases or clamps the whole plate by opening or closing to control the whole plate to fall onto the whole plate conveying support 311.

[0043] Furthermore, the transfer and flipping structure 304 includes a loading plate 317, a transfer mechanism 318, and a flipping mechanism 319. The transfer mechanism 318 is used to move the cut PCB lamp board 13 from the output end of the board cutting structure 303 to the loading seat, and the flipping mechanism 319 is used to flip the PCB lamp board 13 placed on the loading seat from a horizontal posture to a vertical posture.

[0044] The transfer mechanism 318 includes a suction cup assembly 701 for adsorbing the PCB light board 13, and a lifting cylinder 702 and a translation cylinder 703 for driving the suction cup assembly 701 to lift and move horizontally. The flipping mechanism 319 includes a screw conveying unit 704 for translating the loading plate 317, a clamping block 705 for clamping the PCB light board 13, and a rotary cylinder 706 for driving the clamping block 705 to rotate.

[0045] The suction cup assembly 701 of the transfer mechanism 318 moves to above the whole board conveying bracket 311 under the drive of the lifting cylinder 702 and the translation cylinder 703. It descends to adsorb the cut PCB lamp board 13, rises and moves horizontally to the loading seat of the transfer flipping structure 304, and places the lamp board horizontally on the loading seat.

[0046] In addition, the entire board is spliced ​​together by multiple PCB light boards 13 with LEDs. There are gaps between the PCB light boards 13, and they can be divided into multiple single PCB light boards 13 by horizontal cutting.

[0047] During assembly, the clamping and moving mechanism 312 drives the entire board to move step by step, and together with the traversing mechanism 314 drives the cutting unit 313 to cut horizontally, realizing the automatic and precise separation of the entire board, replacing manual board breaking or cutting, improving the efficiency and consistency of board separation. The abutment control unit 316 controls the entire board to fall orderly onto the conveying bracket through opening and closing actions, avoiding board stacking or jamming, and ensuring continuous and stable material supply. The transfer mechanism 318 moves the cut PCB light board 13 to the flipping mechanism 319, which turns it from a horizontal posture to a vertical posture, making it easier to insert into the conductive strip 11 later, simplifying the difficulty of picking and positioning, and further improving the smoothness of automated assembly.

[0048] It should be noted that the entire board is assembled from multiple PCB light boards 13 with LEDs. There are gaps between the PCB light boards 13, and they can be divided into multiple individual PCB light boards 13 by simply making horizontal cuts.

[0049] Preferably, the whole plate conveying bracket 311 is provided with a waste recycling channel 707, and the edge material generated after the whole plate is cut will fall into the waste recycling channel 707 for recycling.

[0050] like Figure 10 , Figure 11 As shown, as a further explanation of the embodiment of the upper cover storage module 401, the upper cover storage module 401 includes an upper cover loading seat 411, an upper cover loading frame 412 slidably disposed on the upper cover loading seat 411, a second sliding unit 413 for driving the upper cover loading frame 412 to slide, and an upper cover conveying line 414 for connecting the upper cover loading frame 412 to the discharge end.

[0051] Specifically, the upper cover feeding frame 412 is provided with several upper cover feeding slots 415. The bottom of the upper cover feeding slot 415 is provided with a second discharge port 416 for the upper cover 12 to be discharged. The upper cover 12 is vertically stacked in the upper cover feeding slot 415. The upper cover feeding seat 411 is provided with a second pushing unit 417. The second pushing unit 417 pushes the upper cover 12 from the second discharge port 416 to the upper cover conveyor line 414, and drives the upper cover 12 to flip from a vertical posture to a horizontal posture during the pushing process.

[0052] Because the diameter of the second discharge port 416 is smaller than the width of the top cover 12 in the vertical state, the vertically stacked top covers 12 cannot fall directly from the second discharge port 416. Only when the second pushing unit 417 pushes out the bottom top cover 12, the top cover 12 is forced to flip from the vertical posture to the horizontal posture under the limitation of the discharge port diameter in order to pass through. This realizes the integrated action of discharging and flipping at the same time. There is no need to set up an additional independent flipping mechanism 319, nor is there a need to add a material blocking device. The module structure is compact and simple, reducing the equipment manufacturing cost.

[0053] like Figure 1 , Figure 12 As shown, further, an upper cover clamping assembly 801 is provided between the upper cover mounting assembly 8 and the unloading assembly 9. The upper cover clamping assembly 801 includes a clamping block 802 and a clamping unit 803 that drives the clamping block 802 to move up and down. After the upper cover mounting assembly 8 completes the initial fastening between the upper cover 12 and the base 10, the semi-finished socket is transported to the upper cover clamping assembly 801 station by the conveying fixture 3. The clamping unit 803 drives the clamping block 802 to move down and applies a predetermined pressure to the upper cover 12, so that the snap-fit ​​structure between the upper cover 12 and the base 10 is fully fastened in place, ensuring that the upper cover 12 and the base 10 are assembled tightly and without gaps, avoiding the upper cover 12 from loosening during subsequent circulation or use due to incomplete fastening, effectively ensuring the firmness and consistency of the product assembly quality, and improving the finished product qualification rate.

[0054] like Figure 1 , Figure 9As shown, a vision inspection component 601 is provided between the PCB light board mounting assembly 7 and the top cover mounting assembly 8. The vision inspection component 601 includes an inspection bracket 602 and an inspection camera 603 mounted on the inspection bracket 602. The inspection camera 603 is positioned facing the connection area between the PCB light board 13 and the conductive strip 11, which enables online and accurate imaging inspection of the insertion status. It can identify defects such as misaligned insertion and incomplete contact in a timely manner before the product enters the next process, avoiding defective products from flowing into subsequent assembly processes and causing rework waste. This effectively reduces production losses and improves product yield and production line quality control level.

[0055] like Figure 1 , Figure 13 As shown in the further explanation of the embodiment of the unloading component 9, the unloading conveyor line 501 includes a first unloading line 503 for conveying qualified products and a second unloading line 504 for conveying unqualified products. The unloading transfer module 502 includes an unloading seat 505, an unloading suction cup 506 disposed on the unloading seat 505, and an unloading moving module 507 for driving the unloading seat 505 to move. The first unloading line 503 and the second unloading line 504 respectively convey qualified products and unqualified products. With the help of the unloading moving module 507, the suction cup is driven to transfer the assembled sockets to the corresponding conveyor line according to the test results. This realizes the automatic sorting and unloading of finished products, avoids the mixing of qualified products and unqualified products, and simplifies the subsequent manual sorting process.

[0056] Preferably, the machine tool 1 is provided with a finished product unloading frame 804, and the machine tool 1 is provided with an unloading robot or unloading gripping module 805, which can put the socket of the first unloading line 503 into the finished product unloading frame 804.

[0057] like Figure 1 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown, as a further explanation of the specific structure of the assembly conveyor line 2, the assembly conveyor line 2 includes a jig conveyor line 901 and a jig return line 902 arranged parallel to each other, a first push module 903 for pushing the conveying jig 3 to move along the jig conveyor line 901, jig lifting modules 904 respectively arranged at both ends of the jig conveyor line 901 and the jig return line 902, and a second push module arranged at the jig lifting module 904 for pushing the conveying jig 3 from the jig lifting module 904 to the jig conveyor line 901 or the jig return line 902. A conveyor belt is provided on the jig return line 902 to realize the automatic return of the conveying jig 3.

[0058] The first pushing module 903 includes a feeding rod 905, a feeding unit 906 that drives the feeding rod 905 to slide, and a lifting cylinder 909 that drives the feeding rod 905 up and down. The second pushing module 910 includes a feeding rod 905 and a feeding unit 906 that drives the feeding rod 905 to slide. The fixture lifting module 904 includes a lifting platform 907 and a lifting cylinder 908 that drives the lifting platform 907 to move up and down.

[0059] Specifically, the fixture conveyor line 901 and the fixture return line 902 are arranged parallel to each other vertically, making full use of the vertical space of the machine 1 and reducing the equipment footprint. The first push module 903 pushes the conveyor fixture 3 along the fixture conveyor line 901 through each assembly station in sequence, completing all processes such as loading the base 10, installing the conductive strip 11, installing the PCB lamp board 13, installing the top cover 12, and unloading. After unloading, the conveyor fixture 3 is transferred to the fixture return line 902 by the fixture lifting module 904 at one end, and then pushed by the second push module to the fixture return line 902 and returned to the starting end. Then it is lifted to the fixture conveyor line 901 by the fixture lifting module 904 at the other end, realizing the recycling of the conveyor fixture 3. The fixture return does not require manual handling, reducing the number of fixtures and the cost of use. At the same time, it ensures that the flow rhythm of the conveyor fixture 3 between each station is stable and controllable, improving the automation level and operating efficiency of the production line.

[0060] Preferably, the fixture conveying line 901 is provided with a fixture positioning structure 911, which includes a positioning block 912 and a positioning unit 913 for driving the positioning block 912 to move toward the conveying fixture 3, and the conveying fixture 3 is provided with a positioning groove 914 for the positioning block 912 to be inserted.

[0061] The fixture positioning structure 911 also includes a horizontal abutment plate 915 abutting against the other side of the base 10, and a pulling cylinder 916 that drives the horizontal abutment plate 915 to move, so as to keep the base 10 in a stable horizontal position.

[0062] A fixture positioning structure 911 is set at the position of the fixture conveyor line 901 corresponding to each assembly station. When the conveying fixture 3 is pushed to the predetermined station by the first push module 903, the positioning unit 913 drives the positioning block 912 to insert into the positioning groove 914 on the conveying fixture 3, so as to accurately lock the conveying fixture 3 at the station. This avoids the assembly accuracy being affected by the fixture moving or shifting during the assembly process such as the insertion of the conductive strip 11, the insertion of the PCB lamp board 13, or the pressing of the top cover 12. The cooperation between the positioning block 912 and the positioning groove 914 is simple and reliable, with high positioning accuracy and good repeatability. This effectively ensures the positional stability of the conveying fixture 3 when each installation module is in operation, and reduces the assembly defect rate caused by positioning deviation.

[0063] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
