Description

Technical Field

[0001] This application relates to the technical field of screwdriver adapters, and more particularly to a screwdriver adapter assembly device. Background Technology

[0002] In the structural design of electronic appliances, communication appliances, and mechanical products, screw connections are the most common method. Therefore, screwdrivers are common tools in the assembly process of these products. When using screwdrivers, different screw sizes need to be dealt with, so adapters are used to change different sizes of screwdriver bits to improve the assembly efficiency of the products.

[0003] Adapters generally consist of interconnected connecting rods, sleeves, and magnets installed inside the sleeves. In existing technologies, it is generally necessary to manually press one end of the connecting rod into the sleeve and then press the magnet into the sleeve at the end away from the connecting rod. The installation of adapters requires manual assembly in conjunction with hydraulic equipment and requires two clamping operations. As a result, the assembly efficiency and quality of adapters are low and need to be improved. Summary of the Invention

[0004] To improve the assembly efficiency and quality of adapters, this application provides a screwdriver adapter assembly device.

[0005] This application provides a screwdriver adapter assembly device, which adopts the following technical solution: A screwdriver adapter assembly device includes a body and an assembly device disposed on the body, the assembly device comprising: Turntable 1 and turntable 2 are mounted on the machine body by rotating on a rotating shaft, and multiple corresponding placement slots 1 and 2 are arranged in a circular array around the axis of the rotating shaft; The feeding mechanism, hydraulic mechanism, installation mechanism, and unloading mechanism are all included. The feeding mechanism is used to place the sleeve and connecting rod into placement slot one and placement slot two respectively; the sleeve and connecting rod are sequentially passed through the hydraulic mechanism, the installation mechanism and the unloading mechanism and then rotated back to the feeding mechanism; the hydraulic mechanism is used to press the connecting rod into one end of the sleeve, and the installation mechanism is used to press the magnet into the other end of the sleeve; the unloading mechanism is used to push the sleeve and connecting rod to fall for unloading.

[0006] By adopting the above technical solution, the feeding mechanism places the sleeve and connecting rod into placement slot one and placement slot two respectively. Turntable one and turntable two rotate coaxially and synchronously at intervals, driving the sleeve and connecting rod to be precisely aligned throughout the process, and then sequentially flow to each station. The hydraulic mechanism is activated to squeeze and press the connecting rod and sleeve together as one unit. The installation station presses the magnet into the inside of the sleeve. Finally, the finished product flows to the unloading station and is pushed out for collection. The turntable continues to rotate, realizing continuous cyclic assembly.

[0007] The sleeve and connecting rod are placed on two separate turntables and rotate synchronously throughout the process. No secondary alignment is required during pressing and assembly, resulting in smaller coaxiality errors during assembly. At the same time, the time wasted on step-by-step feeding and secondary positioning is eliminated, and the overall assembly efficiency is greatly improved compared to the single turntable step-by-step assembly scheme, thus improving the assembly quality and efficiency of the adapter.

[0008] Turntable 1 and Turntable 2 are customized with placement slots 1 and 2 respectively, tailored to the external dimensions of the sleeve and connecting rod. This ensures that the sleeve and connecting rod can be aligned, achieving optimal positioning for each. This avoids the positioning looseness or jamming issues that can occur when a single slot accommodates two different parts simultaneously, resulting in better workpiece placement stability and further improving the assembly quality and efficiency of the adapter. Moreover, the coaxial stacked arrangement of the two turntables reduces the equipment's footprint, and the workstations are compactly arranged along the circumference, resulting in higher space utilization compared to linear assembly lines and better suitability for workshop production line layouts.

[0009] Optionally, the hydraulic mechanism includes: The positioning block and hydraulic components are both located in the machine body. When the hydraulic mechanism is activated, it pushes the connecting rod to approach and moves the sleeve, so that the sleeve abuts against the positioning block for positioning, until one end of the connecting rod is pressed into the sleeve.

[0010] By adopting the above technical solution, the workpiece is transferred to the hydraulic mechanism. The hydraulic mechanism is activated, first contacting the end face of the connecting rod and pushing it to move towards the sleeve. After the connecting rod initially contacts the sleeve, it drives the sleeve to move synchronously towards the positioning block until the other end face of the sleeve abuts against the positioning block to form a hard limit. The hydraulic mechanism continues to output the set pressure to press the connecting rod completely into the sleeve, realizing a firm connection between the two.

[0011] The positioning block provides rigid mechanical limits, and the pressing depth is precisely guaranteed by mechanical dimensions, unaffected by hydraulic pressure fluctuations or workpiece dimensional tolerances. The consistency of pressing quality is far superior to pressure control schemes without positioning. The sleeve end face fits the positioning block as a whole, ensuring uniform force during pressing and guaranteeing the coaxiality of the connecting rod and sleeve during pressing. This avoids product scrap caused by uneven pressing. Moreover, the pure rigid positioning structure has no complex sensing and feedback components, resulting in an extremely low failure rate and no accuracy drift during long-term operation. This significantly improves product quality and further enhances assembly quality.

[0012] Optionally, the hydraulic assembly includes: A hydraulic cylinder is installed in the machine body, and the piston rod can extend into the placement slot 2 to push the connecting rod to move; An arc-shaped spring is installed on the machine body and presses against the sleeve for positioning.

[0013] By adopting the above technical solution, when the workpiece enters the hydraulic cylinder, the arc-shaped spring sheet presses against the outer wall of the sleeve with its own elasticity, pre-pressing the sleeve into the placement groove one, eliminating the gap in the groove, and preventing the sleeve from shifting or deviating before pressing; when the hydraulic cylinder piston rod pushes the connecting rod to press in, the arc-shaped spring sheet continuously provides lateral elastic support, reducing the risk of the sleeve shifting or tilting due to lateral force during the pressing process, and further improving the assembly quality.

[0014] Optionally, the mounting mechanism includes: The mounting block is set in the machine body and has two interconnected channels, namely, channel one is set vertically downwards and channel two is connected to the bottom of channel one and aligned with the placement slot one. The material conveying assembly is used to place and convey multiple magnets that attract each other, so that a magnet located on the outside of the material conveying assembly is positioned against the mounting block. The push-down component moves the magnet that is against the mounting block downwards to the connection point of channel one and channel two. The horizontal push assembly is used to push the magnet located on channel two into the sleeve, and push the sleeve against the turntable two for positioning, until the magnet is pressed into the sleeve. During the movement, the magnet is attracted to the horizontal push assembly for positioning. The horizontal push assembly moves back to pull the sleeve closer to the mounting block, so that the sleeve is against the mounting block for positioning, and the horizontal push assembly is disengaged from the magnet.

[0015] By adopting the above technical solution, multiple magnets are attracted to each other and placed on the conveying assembly for transport. One magnet is located outside the conveying assembly and is positioned against the mounting block, aligned with channel one. The pushing assembly pushes the magnet against the mounting block vertically down along channel one into channel two. The horizontal pushing assembly extends forward, attracts the magnet, and pushes it horizontally into the sleeve. At the same time, it pushes the sleeve closer to turntable two, positioning it against turntable two. The horizontal pushing assembly continues to move the magnet until the installation is complete. The horizontal pushing assembly moves back, driving the magnet and sleeve closer to the mounting block, positioning the sleeve against the mounting block. The horizontal pushing assembly continues to move back, disengaging from the magnet, completing the precise assembly of a single magnet.

[0016] The L-shaped flow channel with vertical material feeding and horizontal pushing enables a smooth transition from batch feeding to single-piece assembly of magnets, avoiding the stacking and jamming problems that are prone to occur with straight pushing. The smoothness of magnet conveying and assembly is greatly improved, making the assembly process fast and stable, and improving assembly quality and efficiency.

[0017] During the pushing process, the magnetic positioning ensures that the magnet does not shift or fall off, resulting in precise assembly. After the magnet enters the sleeve and pushes it to move, it is positioned against the turntable 2, completing the final assembly of the magnet. During the return process, the sleeve is pulled against the mounting block for positioning. By achieving hard positioning of the sleeve at two positions, the positioning effect of the sleeve can be greatly improved. This also solves the industry pain point of the magnet being carried back with the push rod in traditional solutions, leading to missed installations. At the same time, no other separate positioning mechanism is required, resulting in a simple and stable structure that further improves assembly quality and efficiency.

[0018] Optionally, the feeding assembly includes: The material conveying track is set on the machine body and extends horizontally to the mounting block. Multiple magnets are placed on the material conveying track after they attract each other, and one magnet is located outside the material conveying track and is positioned against the mounting block. A push rod is set on the mounting block. The magnet that abuts against the mounting block is attracted to the piston rod of the push rod for positioning. After the push assembly pushes the magnet to move down and then moves back to its original position, the piston rod of the push rod extends and attracts the magnet. After retracting, it pulls all the magnets to move, so that one magnet abuts against the mounting block for positioning.

[0019] By adopting the above technical solution, multiple magnets attract each other with their own magnetism within the conveying track, arranging themselves neatly in a row. The foremost magnet is located outside the conveying track and is positioned against the side wall of the mounting block. After one magnet is pushed down, the push rod extends forward, attracts the end face of the next magnet, and then retracts, pulling the entire magnet assembly to move precisely to the top of the channel. The magnet continues to be positioned against the mounting block and the push rod, awaiting the next push-down assembly.

[0020] Relying on the magnets themselves, automatic alignment is achieved, eliminating the need for material separation or distribution mechanisms. The material conveying structure is extremely simple and cost-effective, and avoids the problems of magnet chipping and breakage caused by mechanical material distribution, significantly reducing material loss. The push rod uses magnetic attraction for material replenishment, ensuring precise and controllable positioning. The consistent replenishment position ensures accurate alignment of the magnets with the channel during push-down, improving assembly quality and efficiency.

[0021] Meanwhile, compared to the existing technology that continuously pushes the material on the conveying track forward by a pusher rod, moving it forward by the thickness of a magnet each time, this application only needs to move the magnet thickness each time. After the magnet is loaded, it needs to be moved back to the initial position, resulting in an excessively long movement distance and a complex drive structure. This application utilizes the mutual attraction of magnets, using the pusher rod to attract the magnets and pull the entire magnet to move. This means that only the magnet thickness needs to be moved back and forth each time, which can significantly shorten the movement distance. Moreover, the drive structure is simple and stable, making the loading process more stable and improving assembly quality and efficiency.

[0022] Optionally, the pushdown component includes: The pusher is located on the machine body, and the piston rod is set vertically downward; The push plate is set on the piston rod of the pusher and is used to push the magnet down to the connection between channel one and channel two and then move up to disengage from the magnet.

[0023] By adopting the above technical solution, the pusher drives the pusher plate to extend downwards, pushing the magnet to move smoothly down along the inner wall of channel one; the magnet moves to the connection between channel one and channel two, waiting for horizontal push assembly, thereby realizing the feeding of the magnet.

[0024] Optionally, a sensor electrically connected to the horizontal pushing assembly and the downward pushing assembly is provided on the second channel; when the magnet moves down to the connection between the first channel and the second channel, it comes into contact with the sensor and is sensed, the horizontal pushing assembly is activated to push the magnet to move, if the sensor does not sense the magnet, the downward pushing assembly continues to push the magnet down until the sensor senses the magnet.

[0025] By adopting the above technical solution, after the magnet falls into channel two, the sensor detects in real time whether there is a magnet in the channel. After the signal is detected, the horizontal push component starts to push and assemble; if no magnet is detected, the signal is fed back to the downward push component, which automatically pushes a magnet to replace it, forming a detection-replenishment closed loop, which increases the probability of successful magnet installation and greatly improves the assembly quality.

[0026] Optionally, a sleeve extending to one end of the channel is threaded onto the second channel. Multiple elastic rings are spaced apart on one end of the sleeve near the first channel and on its inner sidewall. The inner diameter of the elastic rings is smaller than the outer diameter of the magnet. When the magnet moves down to the connection between the first and second channels, the elastic rings abut against the magnet for positioning. The horizontal pushing assembly pushes the magnet to squeeze the multiple elastic rings in sequence before it passes through.

[0027] By adopting the above technical solution, after the magnet falls into channel two, it squeezes the elastic ring located on the sleeve cross-section. The elastic ring pushes the magnet against the connection between channel one and channel two for positioning, preventing the magnet from moving freely and shifting. The horizontal push assembly starts and pushes the magnet to squeeze multiple elastic rings in sequence and move into the sleeve. During the squeezing process, the force pushes the magnet to be tightly attached to the horizontal push assembly, thereby further reducing the risk of the magnet falling off the horizontal push assembly. This can greatly reduce the risk of magnet assembly failure, improve the accuracy of the assembly position, and greatly improve the assembly quality.

[0028] Meanwhile, the elastic ring located on the end face of the sleeve presses against channel two for positioning, which can locate the position of the sleeve and also allows for the replacement of sleeves and elastic rings of different sizes, thus improving the adaptability.

[0029] Optionally, the lateral push assembly includes; The transverse pusher is located in the machine body; A horizontal push rod is installed on the piston rod of the horizontal push component. When the horizontal push component is activated, it pushes the horizontal push rod closer to and moves the magnet located in the second channel. During the movement, the magnet is attracted to the horizontal push rod for positioning.

[0030] By adopting the above technical solution, the horizontal pusher drives the horizontal push rod to extend forward. After the end of the horizontal push rod approaches the magnet, it uses magnetic force to attract and fix the magnet. The horizontal push rod continues to move forward, smoothly pushing the magnet into the sleeve. After assembly, the horizontal push rod retracts, and the magnet is blocked by the sleeve and separated from the horizontal push rod, completing one assembly action.

[0031] No mechanical grippers are required; the magnets can be precisely fixed using magnetic force. The structure is extremely simple, making it particularly suitable for micro-assembly scenarios with small magnets. It avoids problems such as gripper interference and crushing of magnets, resulting in a higher assembly yield. The pure magnetic attraction eliminates mechanical wear, and the end face of the horizontal push rod is free from gripping fatigue and deformation. The accuracy remains stable over long-term use, and the cost of spare parts replacement is extremely low, making it suitable for large-scale continuous production.

[0032] Optionally, the feeding mechanism includes: The feeding plate is set in the machine body and extends between turntable one and turntable two. It has an arc-shaped abutment surface that contacts the sleeve, and a guide surface that connects the top of the abutment surface to the bottom of the abutment surface and is inclined downward. Multiple auxiliary plates are installed on the machine body, located below turntable one and turntable two, and also have guide surfaces; The collection box is used to collect the adapters; the rotating drive of the first and second turntables drives the sleeve to rotate to the feeding plate and then rotates again, so that the sleeve or connecting rod is squeezed out after contacting the abutment surface and falls onto multiple guide surfaces, and moves into the collection box for collection under the guidance of the guide surfaces.

[0033] By adopting the above technical solution, when the finished product rotates to the unloading station with the double turntables, the side wall of the sleeve or connecting rod first contacts the arc-shaped abutment surface of the unloading plate; as the turntables continue to rotate, the arc-shaped surface gradually squeezes the sleeve or connecting rod outward; after the sleeve or connecting rod completely leaves the placement slot, it falls onto multiple guide surfaces for guidance until it is moved into the collection box for collection, thus completing the automatic unloading and collection; if the sleeve or connecting rod falls under the action of gravity, it is also guided to the collection box for collection through multiple guide surfaces.

[0034] No cylinders, robotic arms, or other driving components are required. Material feeding is achieved entirely by the rotation of turntables one and two. The structure is extremely simple, the manufacturing cost is low, and there is no additional energy consumption, resulting in almost zero maintenance costs during long-term operation. The workpiece is extruded gradually through an arc-shaped transition surface. The process is smooth with no rigid impacts or scratches, which will not damage the coating or appearance of the sleeve surface. The finished product yield is much higher than that of rigid block scraping solutions, improving the quality of shipped products.

[0035] The feeding plate can extend into the gap between the two turntables, perfectly adapting to the dual-turntable architecture of this equipment and solving the problem that traditional feeding mechanisms cannot be applied to double-layer turntables. Overall installation and debugging are simple, and it is highly adaptable when changing products. The inclined guide surface guides the workpiece to slide smoothly into the collection box, resulting in a low drop height and minimal impact, preventing workpiece damage, deformation, and paint chipping. It also enables automatic centralized collection, facilitating subsequent process transfer. Furthermore, multiple guide surfaces provide more stable guidance for the sleeve and connecting rod, further improving product quality.

[0036] In summary, this application includes at least one of the following beneficial technical effects: 1. By using two separate turntables for the sleeve and connecting rod, and rotating synchronously throughout the process, no secondary alignment is required during pressing and assembly, resulting in smaller coaxiality errors during assembly. At the same time, it saves the time lost in step-by-step feeding and secondary positioning, greatly improving the overall assembly efficiency compared to the single turntable step-by-step assembly scheme, thus improving the assembly quality and efficiency of the adapter.

[0037] 2. By customizing placement slots one and two for the sleeve and connecting rod respectively using turntable one and slot two, optimal positioning effects are achieved, resulting in better workpiece placement stability and further improving the assembly quality and efficiency of the adapter. Moreover, the coaxial stacked arrangement of the two turntables reduces the equipment's footprint, and the workstations are compactly arranged along the circumference, resulting in higher space utilization compared to linear assembly lines and making it more suitable for workshop production line layouts.

[0038] 3. Through magnetic positioning during the pushing process, the magnet does not shift or fall off, ensuring precise assembly. After the magnet enters the sleeve and pushes the sleeve to move, it is positioned by the sleeve against the second turntable, thus completing the final assembly of the magnet. During the return process, the sleeve is pulled against the mounting block for positioning. Hard positioning of the sleeve is achieved through two positions, which greatly improves the positioning effect of the sleeve and solves the industry pain point of the magnet being brought back with the push rod in the traditional solution, resulting in missing parts. At the same time, no other separate positioning mechanism is required, the structure is simple and stable, and further improves the assembly quality and efficiency. Attached Figure Description

[0041] The following provides a further detailed description of this application.

[0042] This application discloses a screwdriver adapter assembly device.

[0043] Reference Figures 1-3 The screwdriver adapter assembly equipment includes a body 1 and an assembly device 2 installed on the body 1. The assembly device 2 first presses one end of the connecting rod 12 into one end of the sleeve 11, and then presses the magnet 13 into the end of the sleeve 11 away from the connecting rod 12.

[0044] The assembly device 2 includes a turntable 1 21, a turntable 22, a feeding mechanism 3, a hydraulic mechanism 4, a mounting mechanism 5, and a unloading mechanism 8. A vertical mounting base 19 is fixedly installed on the upper surface of the machine body 1. A horizontal rotating shaft 25 is rotatably installed on the side wall of the mounting base 19. A servo motor 26 connected to the rotating shaft 25 is fixedly installed on the upper surface of the machine body 1. The servo motor 26 is used to drive the rotating shaft 25 to rotate. A vertical plate 14 is fixedly installed on the upper surface of the machine body 1 and on the side of the mounting base 19 away from the servo motor 26. The vertical plate 14 and the upper surface of the mounting base 19 are fixedly connected by a horizontal connecting plate 15.

[0045] Turntable 1 21 and turntable 22 are both coaxially fixed on the rotating shaft 25 and located between the mounting base 19 and the vertical plate 14. At the same time, they have the same outer diameter. Turntable 1 21 is located between turntable 22 and the mounting base 19. Multiple placement slots 1 23 are arranged in a circular array around the axis of the rotating shaft 25 on the outer circular surface of turntable 1 21. Multiple placement slots 24 corresponding to placement slots 1 23 are arranged on the outer circular surface of turntable 22. Placement slots 1 23 and 24 are both opened along the axis of the rotating shaft 25 and pass through turntable 1 21 and turntable 22 respectively. Placement slot 1 23 is adapted to sleeve 11 and is used to place and position sleeve 11. Placement slot 24 is adapted to connecting rod 12 and is used to place and position connecting rod 12.

[0046] The feeding mechanism 3, hydraulic mechanism 4, mounting mechanism 5, and unloading mechanism 8 are all located on the machine body 1. The feeding mechanism 3 is used to place the sleeve 11 and the connecting rod 12 onto the placement slot 1 23 and the placement slot 24 respectively, so that the axes of the sleeve 11 and the connecting rod 12 coincide and are aligned. The rotation of the turntable 1 21 and the turntable 22 drives the sleeve 11 and the connecting rod 12 to pass through the hydraulic mechanism 4, the mounting mechanism 5, and the unloading mechanism 8 in sequence and then return to the feeding mechanism 3. When the sleeve 11 and the connecting rod 12 rotate to align with the mounting mechanism 5, the sleeve 11 and the connecting rod 12 are located at the highest point of the turntable 1 21 and the turntable 22.

[0047] The feeding mechanism 3 includes two guide rails 31 and two feeders. The two guide rails 31 are fixedly installed on the machine body 1, and their bottom ends extend downwards at an angle to near turntable 1 21 and turntable 22. Two feeders are fixedly installed on the machine body 1. The two feeders are respectively connected to the top of the two guide rails 31. The feeders can be vibrating feeders 32, or they can be push-plate feeders 33. Both types of feeders are existing technology structures and will not be described in detail here.

[0048] Two feeding machines neatly arrange the sleeve 11 and connecting rod 12 on two guide rails 31, and cause the sleeve 11 and connecting rod 12 to move downwards under gravity and subsequent pushing, so that one sleeve 11 moves down to place in placement slot one 23 and one connecting rod 12 moves down to place in placement slot two 24; turntable one 21 and turntable two 22 rotate upwards to drive the sleeve 11 and connecting rod 12 to their highest position and align with the hydraulic mechanism 4. At the same time, each of the two guide rails 31 is equipped with a detector electrically connected to an audible and visual alarm. If the detector fails to detect the sleeve 11 or connecting rod 12, the audible and visual alarm will sound an alarm.

[0049] The hydraulic mechanism 4 includes a positioning block 41 and a hydraulic component 42. The positioning block 41 is fixedly installed on the side wall of the mounting base 19 near the turntable 21 and extends vertically upward above the turntable 21. The hydraulic mechanism 4 is located on the connecting plate 15 and pushes the connecting rod 12 to move.

[0050] The hydraulic assembly 42 includes a hydraulic cylinder 43 and an arc-shaped spring piece 44. The hydraulic cylinder 43 is fixedly installed on the lower surface of the connecting plate 15, and the piston rod of the hydraulic cylinder 43 is arranged parallel to the placement slot 1 23 and the placement slot 24, and is located on the side of the turntable 22 and the turntable 1 21 away from the mounting base 19. After the piston rod of the hydraulic cylinder 43 extends, it extends into the placement slot 24, pushes the connecting rod 12 close to and inserts into the sleeve 11, and pushes the sleeve 11 to move simultaneously until the sleeve 11 abuts against the positioning block 41 for positioning. The connecting rod 12 continues to move until it is pressed into the sleeve 11 for positioning, so that the connecting rod 12 and the sleeve 11 are interference-fitted to achieve installation. The arc-shaped spring piece 44 is fixedly installed on the side wall of the positioning block 41. When the sleeve 11 rotates to align with the hydraulic cylinder 43, the arc-shaped spring piece 44 presses against the sleeve 11 for positioning.

[0051] Reference Figure 1 , Figures 3-5 Turntable 1 21 and turntable 22 rotate downwards to the installation mechanism 5 to install magnet 13. At this time, the openings of placement slot 1 23 and placement slot 24 are in a horizontal state or tilted upwards. At the same time, the placement slot 1 23 and placement slot 24 corresponding to the two guide rails 31 are in the same state as the placement slot 1 23 and placement slot 24 at this time. This is all to reduce the risk of sleeve 11 and connecting rod 12 falling from the inside.

[0052] The mounting mechanism 5 includes a mounting block 51, a material conveying assembly 52, a downward pushing assembly 6, and a horizontal pushing assembly 7. The mounting block 51 is fixedly mounted on the side wall of the mounting base 19 away from the material guide rail 31. A vertical and flat channel 55 is provided in the mounting block 51. The thickness of the channel 55 is greater than or equal to the thickness of the magnet 13. A passage groove 58 connected to the top of the channel 55 is provided on the side wall of the mounting block 51 away from the turntable 21. A bearing plate 17 extending vertically upward to the top of the mounting block 51 is fixedly mounted on the top of the mounting block 51 and above the passage groove 58. A horizontal channel 56 connected to the bottom of the channel 55 is provided on the side wall of the mounting block 51 near the turntable 21. The cross-section of the channel 56 is circular and allows the magnet 13 to pass through. The diameter of the channel 56 is greater than the outer diameter of the magnet 13 and is aligned with the placement groove 23 and the placement groove 24.

[0053] The conveying assembly 52 is used to place multiple magnets 13 that attract each other. The conveying assembly 52 extends horizontally to the mounting block 51, so that the magnets 13 located on the outside of the conveying assembly 52 abut against the channel 55 for positioning. The conveying assembly 52 includes a conveying track 53 and a push rod 54. Multiple support plates 16 are fixedly installed horizontally at intervals on the servo motor 26. The conveying track 53 is fixedly installed on the upper surface of the multiple support plates 16 and extends horizontally into the passage groove 58. After the multiple magnets 13 attract each other, they are placed on the conveying track 53 for conveying. The conveying direction is horizontal, and the magnet 13 closest to the channel 55 is located on the outside of the conveying track 53 and abuts against the channel 55 for positioning. At the same time, this magnet 13 is aligned with the channel 55.

[0054] The push rod 54 is an electric push rod or a cylinder. The push rod 54 is fixedly installed on the side wall of the mounting block 51 near the turntable 21. The piston rod of the push rod 54 extends horizontally through the mounting block 51 to the connection between the channel 55 and the passage groove 58, so that the magnet 13 located outside the conveying track 53 is attracted to the piston rod of the push rod 54 for positioning.

[0055] The push assembly 6 includes a pusher 61 and a pusher plate 62. The pusher 61 is an electric push rod or a cylinder. The pusher 61 is fixedly installed on the side wall of the support plate 17, and the piston rod is set vertically downward. The pusher plate 62 is set on the piston rod of the pusher 61 and slides vertically through the top of the mounting block 51, extending to the connection between the channel 1 55 and the passage groove 58. The pusher plate 62 is aligned with the channel 1 55, and the pusher plate 62 is initially located above the multiple magnets 13. At the same time, the pusher plate 62 is made of a material that cannot be attracted by the magnets 13. The material can be plastic, aluminum, etc.

[0056] The pusher 61 drives the pusher plate 62 to move downwards. The pusher plate 62 pushes the magnet 13, which is adsorbed on the piston rod of the pusher rod 54, downwards into the channel 1 55. The pusher plate 62 continues to move downwards, pushing the magnet 13 to move until the magnet 13 moves to the connection between the channel 1 55 and the channel 2 56. The pusher 61 then drives the pusher plate 62 to move upwards back above the magnet 13. The piston rod of the pusher rod 54 approaches the magnet 13, causing the magnet 13 to be adsorbed on the piston rod of the pusher rod 54. The pusher rod 54 moves back, pulling the entire magnet 13 closer to the channel 1 55, so that one magnet 13 moves to the outside of the conveying track 53 and is positioned against the channel 1 55.

[0057] A third channel 57, communicating with the second channel 56, is provided at the bottom of the mounting block 51 on the side opposite to the second channel 56. The third channel 57 is coaxially arranged with the second channel 56, and the diameter of the third channel 57 is smaller than the diameter of the second channel 56. The transverse push assembly 7 includes a transverse push member 71 and a transverse push rod 72. The transverse push member 71 is an electric push rod or a cylinder. The transverse push member 71 is fixedly installed on the lower surface of the support plate 16. The transverse push rod 72 is fixedly installed on the piston rod of the transverse push member 71, and the transverse push rod 72 is coaxially slidably installed on the third channel 57.

[0058] Magnet 13 is moved to the connection between channel 2 56 and channel 1 55; the horizontal pusher 71 starts to drive the horizontal push rod 72 to approach magnet 13, and fixes magnet 13 by magnetic attraction. After magnet 13 moves into sleeve 11, it is pushed to approach and abut against turntable 22 for positioning. The horizontal push rod 72 continues to push magnet 13 until magnet 13 is pressed into sleeve 11 for positioning. The horizontal pusher 71 drives the horizontal push rod 72 to move back, magnet 13 and sleeve 11 move back, so that sleeve 11 abuts against mounting block 51 for positioning. After the horizontal push rod 72 is separated from magnet 13, it moves back to its original position to install magnet 13 into sleeve 11.

[0059] The lower surface of the mounting block 51 has a threaded hole that connects to the connection between channel 1 55 and channel 2 56. A sensor 18 is threadedly connected to the threaded hole. The sensor 18 is electrically connected to the control box. The control box controls the start and stop of the horizontal push assembly 7 and the downward push assembly 6, thereby realizing the electrical connection between the sensor 18 and the horizontal push assembly 7 and the downward push assembly 6. When the magnet 13 moves down to the connection between channel 1 55 and channel 2 56, it presses against the sensor 18 to achieve sensing. After the sensor 18 senses the magnet 13, the horizontal push assembly 7 starts to push the magnet 13 to move. If the sensor 18 does not sense the magnet 13, the downward push assembly 6 continues to move down to push the magnet 13 to replenish the material until the sensor 18 senses the presence of the magnet 13, and then the horizontal push assembly 7 starts to operate.

[0060] A sleeve 27 is coaxially threaded onto channel 2 56. The sleeve 27 is coaxially arranged with channel 2 56, and its inner diameter is larger than that of the magnet 13, allowing the magnet 13 to pass through. Elastic rings 28 are coaxially arranged on the end of the sleeve 27 near channel 1 55 and on the inner wall of the sleeve 27. Multiple elastic rings 28 have the same inner diameter, which is smaller than the outer diameter of the magnet 13 but larger than the outer diameter of the horizontal push rod 72. The cross-section of the elastic rings 28 is arc-shaped. When the magnet 13 falls to the connection between channel 1 55 and channel 2 56, it is located at the end of the sleeve 27. The elastic ring 28 on the surface abuts against the magnet 13 for positioning. At the same time, when the sleeve 27 is threaded onto the second channel 56, the elastic ring 28 abuts against the second channel 56 for positioning, which can reduce the risk of the sleeve 27 rotating and disengaging from the second channel 56. The horizontal push rod 72 approaches and pushes the magnet 13 to move, so that the magnet 13 squeezes multiple elastic rings 28 in sequence and passes through the elastic rings 28. During the squeezing process, the magnet 13 and the horizontal push rod 72 can be more stably and accurately attracted, which further improves the installation quality of the magnet 13.

[0061] The feeding mechanism 8 includes a feeding plate 81, multiple auxiliary plates 82, and a collection box 83. The feeding plate 81 and the multiple auxiliary plates 82 are fixedly installed on the upper surface of the machine body 1. The feeding plate 81 extends between the first turntable 21 and the second turntable 22, and the multiple auxiliary plates 82 are located on both sides of the feeding plate 81 and below the first turntable 21 and the second turntable 22. The feeding plate 81 has an arc-shaped abutment surface 84 that contacts the sleeve 11 or the connecting rod 12, and a guide surface 85 whose top end connects to the bottom of the abutment surface 84 and extends downward at an angle to the outside of the machine body 1. The multiple auxiliary plates 82 also have the same guide surface 85.

[0062] The collection box 83 is placed on the ground and is used to collect the adapter. After the magnet 13 is installed, the turntable 1 21 and the turntable 22 rotate downwards, so that the openings of the placement slot 1 23 and the placement slot 24 face downwards. At the same time, the sleeve 11 and the connecting rod 12 are driven to approach the feeding plate 81, so that the abutment surface 84 contacts the sleeve 11 or the connecting rod 12. The abutment surface 84 pushes the sleeve 11 and the connecting rod 12 out of the placement slot 1 23 and the placement slot 24. Then the sleeve 11 and the connecting rod 12 are guided by the guide surface 85 located on the feeding plate 81 and multiple auxiliary plates 82, so that the sleeve 11 and the connecting rod 12 move into the collection box 83 for collection. At the same time, if the sleeve 11 and the connecting rod 12 fall under the action of gravity during the rotation, they can also move into the collection box 83 for collection under the guidance of multiple guide surfaces 85.

[0063] The working principle of this application embodiment is as follows: The feeding mechanism 3 places the sleeve 11 and connecting rod 12 into the placement slot 1 23 and placement slot 24 respectively. Turntable 1 21 and turntable 2 22 rotate synchronously and intermittently, driving the sleeve 11 and connecting rod 12 to be precisely aligned throughout the process, and then flow to each station in sequence. When it moves to the hydraulic station, the arc-shaped spring 44 presses against the sleeve 11 for positioning. The hydraulic cylinder 43 pushes the connecting rod 12 into the sleeve 11 to complete the installation. When it moves to the installation station, the push assembly 6 pushes the magnet 13 to the connection between channel 1 55 and channel 2 56. The push rod 54 approaches and attracts the magnet 13, pulling the entire magnet 13 forward to replenish the magnet 13. The sensor 18 detects the magnet 13. If the magnet 13 is not present, the push assembly 6 and the push rod 54 repeat the operation until the magnet 13 is present.

[0064] The horizontal pusher 71 starts driving the horizontal pusher rod 72 to push the magnet 13 to squeeze multiple elastic rings 28 in sequence and enter the sleeve 11. The sleeve 11 is pushed against the turntable 22 for positioning. The horizontal pusher rod 72 continues to move and presses the magnet 13 into the sleeve 11 to complete the installation. The horizontal pusher rod 72 moves back to drive the magnet 13 and the sleeve 11 to move back. The sleeve 11 is against the sleeve 27 for positioning. After the horizontal pusher rod 72 is separated from the magnet 13, it continues to move back to its original position. Finally, the sleeve 11 and the connecting rod 12 move down to the collection box 83 under the guidance of the feeding plate 81 and the auxiliary plate 82 for collection. The turntable 1 21 and the turntable 2 22 continue to rotate at the feeding point and then continue to realize continuous cyclic assembly, thereby improving the assembly quality and efficiency of the adapter.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
