Description

Technical Field

[0001] This invention belongs to the technical field of automated assembly equipment for automotive electronic and electrical components, and specifically relates to an automatic assembly device for automotive handle switch magnets. Background Technology

[0002] The car handle switch is a core control component in the automotive electronic and electrical control system. It is mainly used by the driver to conveniently operate the vehicle's turn signals, high and low beam headlight switching, and windshield wipers while driving. Its performance stability and reliability play an important role in the vehicle's driving safety.

[0003] To achieve the aforementioned multiple control functions and effectively improve the durability and lifespan of the switch, modern automotive handle switches generally adopt a non-contact magnetic induction structure. This involves placing a magnet inside the handle and using a fixed Hall effect sensor. The change in the magnetic field caused by the handle's movement identifies the operating position and outputs the corresponding control electrical signal. A typical structure is shown in Chinese Patent Document CN216122375U, which discloses an automotive combination switch. This switch includes a handle with an extension extending rearward from the connecting shaft. A magnet is fixedly mounted on this extension, and a Hall effect chip is fixedly arranged within the magnetic field range of the corresponding magnet. When the driver moves the handle to perform different directional operations, the magnet shifts relative to the handle. The Hall effect chip detects the change in the magnetic field caused by this relative movement and then feeds back different electronic signals to the main control board to issue the operation command.

[0004] The aforementioned magnetic induction structure replaces the traditional mechanical contact transmission structure, simplifying the number of internal parts of the switch, reducing the overall space occupied, and improving the product's durability and service life. In the production process of this type of automotive handle switch that uses the magneto-electric induction principle, the magnet is a key component to ensure the function is realized. It needs to be precisely assembled into the preset mounting position on the handle, and the magnetic pole direction of the magnet must match the corresponding position of the Hall effect sensor to ensure the switch's detection accuracy and functional stability.

[0005] Currently, the magnet assembly process for automotive handle switches mostly relies on manual assembly or simple tooling. Operators must manually disassemble the magnets that are attracted and stacked together, and then place them one by one into the mounting slot of the handle. Existing auxiliary tooling mostly only has basic positioning and limiting functions and cannot achieve automatic continuous supply of magnets or automatic polarity verification. Due to the small size and smooth surface of the magnets, and their tendency to attract and stick together due to their own magnetic force, the disassembly and removal of materials is difficult. Operators are prone to fatigue after long periods of repetitive work, leading to assembly defects such as missing or incorrect magnets. At the same time, the manual assembly process lacks an effective polarity detection step, which easily results in the N and S poles of the magnets being reversed, causing the finished switch to malfunction and requiring rework and reassembly. This directly slows down the overall production line pace and causes additional losses of manpower and material resources. In addition, the low efficiency of manual assembly makes it difficult to meet the needs of batch assembly. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic assembly device for automotive handle switch magnets, in order to solve the technical problems of low efficiency and easy omissions and misassemblies in the existing manual magnet assembly method.

[0007] To solve the above problems, the technical solution of the automatic assembly device for automotive handle switch magnets provided by the present invention is as follows:

[0008] An automatic assembly device for automotive handle switch magnets includes a frame, a handle positioning and conveying mechanism, a magnet queuing and supplying mechanism, a magnet assembly mechanism, a detection component, and a control unit. The handle positioning and transfer mechanism is slidably mounted on the frame to carry the car handle to be assembled and transfer it to the handle assembly station; The magnet queuing and supply mechanism is mounted on the frame to store stacked rows of magnets and transport them row by row toward the magnet assembly station. The magnet assembly mechanism is mounted on the frame and set up corresponding to the magnet assembly station, and is used to press a single magnet at the magnet assembly station into the inside of the car handle at the handle assembly station. The detection component is mounted on the frame or handle positioning and conveying mechanism to detect the magnetic polarity of the magnet pushed toward the car handle; The control unit is connected to the handle positioning and transfer mechanism, the magnet queuing and supply mechanism, the magnet assembly mechanism, and the detection component to coordinate and control each mechanism to sequentially execute the assembly process of handle transfer, magnet pressing, and polarity verification.

[0009] The beneficial effects of this invention are as follows: The invention enables the installation and automatic transfer of the handle via a handle positioning and transfer mechanism; it achieves layered storage and directional delivery of rows of magnets via a magnet queuing and supply mechanism; it completes the pressing operation of magnets into the handle via a magnet assembly mechanism; and it performs magnetic polarity detection on the magnets installed in the handle via a detection component. Finally, the control unit coordinates the operation sequence of each mechanism to automate the handle transfer, magnet pressing, and polarity verification. This invention can replace manual magnet assembly, avoiding omissions and misassemblies caused by human error, while also avoiding the defect of reversed magnetic polarity. It improves the overall efficiency of assembly operations and the consistency of product assembly quality, and is suitable for the needs of mass production.

[0010] Furthermore, the magnet queuing supply mechanism includes a magnet placement seat, a magnet queuing seat, and a magnet replenishment drive. The magnet queuing seat is provided with a magnet queuing groove extending along the magnet conveying direction, and the magnet assembly station is located at the end of the magnet queuing groove. The magnet placement seat is provided with a magnet placement groove facing the magnet queuing groove, which is used to place rows of magnets stacked in layers. The output end of the replenishment drive is facing the inlet end of the magnet placement groove, and is used to push the bottom row of magnets forward into the magnet queuing groove.

[0011] Beneficial effects: The bottom-extraction propulsion method can automatically overcome the magnetic attraction between the upper and lower magnets by using mechanical thrust, realizing the separation and sequential conveying of magnets in whole rows. There is no need to manually separate the magnets that are attracted to each other, solving the problem that magnets are difficult to separate and pick up due to their own magnetic force. At the same time, it ensures that the magnet conveying process is orderly and stable, providing a stable material supply for continuous pressing operations.

[0012] Furthermore, the magnet queuing and supply mechanism also includes a magnetic adsorption component disposed next to the magnet assembly station. The magnetic adsorption component has a magnetic force greater than that of the magnet being assembled, and is used to attract a row of magnets queuing in the magnet queuing slot to the magnet assembly station.

[0013] Beneficial effects: The strong magnetic force generated by the magnetic adsorption component can automatically and reliably pull a row of magnets waiting in the queuing slot to the magnet assembly station, ensuring that the magnets at the magnet assembly station are accurately aligned with the working end of the magnet assembly mechanism, providing an accurate positional reference for subsequent pressing processes.

[0014] Furthermore, the magnet queuing seat has a magnetic suction groove in the extension direction of the magnet queuing groove, and the magnetic adsorption component is disposed in the magnetic suction groove; the depth of the magnetic suction groove is less than the height of the magnetic adsorption component, and the magnetic suction groove and the magnet queuing groove are separated by a baffle, and the magnetic adsorption component adsorbs the magnet to a position that fits against the outer wall of the baffle.

[0015] Beneficial effects: Using the platform as the reference surface for the magnet to rest, the magnet is attracted and adheres to the outer wall of the platform, forming a uniform positioning reference, so that the resting position of each magnet remains consistent; the depth setting of the magnetic suction groove can ensure the smooth transport process of the magnet.

[0016] Furthermore, the magnet assembly mechanism includes a magnet mounting drive and a mounting pin connected to the output end of the magnet mounting drive. The magnet queuing seat is provided with a guide channel that vertically penetrates the magnet queuing slot at the position corresponding to the magnet assembly station. The guide channel is adapted to the mounting pin for guiding the movement of the mounting pin. One side wall of the guide channel is coplanar with the outer side wall of the baffle.

[0017] Beneficial effects: The guide channel provides precise linear motion guidance for the installation of the top pin. The coplanar design of the guide channel and the outer wall of the baffle makes the magnet positioning reference and the pressing guide reference consistent with each other, further improving the pressing accuracy and ensuring that the magnet can be accurately embedded into the preset position of the car handle.

[0018] Furthermore, the magnet holder is integrally formed with a forward blocking part and a lateral blocking part. The forward blocking part is used to block the magnets above the bottom layer in the direction of magnet advancement; the lateral blocking part blocks the magnets laterally in a horizontal and perpendicular direction to the direction of magnet advancement.

[0019] Beneficial effects: The forward stop allows only the bottom row of magnets to be pushed forward each time, achieving automatic separation of single-layer magnets without the need for additional material distribution components; the lateral stop can constrain the stacked magnets from the side, preventing lateral displacement or even collapse of the magnets during falling and conveying, ensuring that the layered stacked magnets can fall and replenish in an orderly manner, and improving the stability and reliability of the feeding process.

[0020] Furthermore, the magnets are detachably connected to a first pressure plate above the magnet assembly station. The first pressure plate is used to limit the magnets at the magnet assembly station in the vertical direction and press the magnetic adsorption component downward.

[0021] Beneficial effects: The first pressure plate can limit and constrain the magnets to be assembled from the top and bottom, preventing the magnets from moving upward and falling out of the magnet queuing slot during the process of being pushed by the installation pin. At the same time, the first pressure plate can press down on the magnetic adsorption component to prevent the magnetic adsorption component from shifting and causing adsorption and positioning failure.

[0022] Furthermore, the magnet queuing seat is detachably connected to a second pressure plate above the magnet queuing slot. The installation position of the second pressure plate is adjustable and is used to limit the magnets in the magnet queuing slot in the vertical direction.

[0023] Beneficial effects: The second pressure plate can limit and constrain the rows of magnets waiting in line in the vertical direction. Its adjustable installation position allows the assembly device to flexibly adapt to magnets of different sizes and specifications, improving the versatility of the entire assembly device.

[0024] Furthermore, a magnetic sensor that communicates with the control unit is provided between the magnet placement seat and the magnet queuing seat.

[0025] Beneficial effects: The magnetic sensor can detect the position status of the magnets in the magnet queuing slot in real time and feed back the magnet inventory information to the control unit. The control unit can then control the magnet replenishment drive to perform replenishment actions in a timely manner based on the detected magnet consumption, so as to avoid material shortages and supply interruptions during the assembly process and ensure that the assembly operation can be carried out continuously and stably.

[0026] Furthermore, the frame includes a base with a linear guide rail on it; the handle positioning and transfer mechanism includes a movable seat, a handle fixing seat, a transfer drive component, and a position sensor. The movable seat is slidably engaged with the linear guide rail, and the drive end of the transfer drive component is connected to the movable seat to drive the movable seat to slide along the linear guide rail. The handle fixing seat has a handle mounting position adapted to the shape of the car handle. The position sensor is installed on the handle fixing seat to detect the position of the car handle. The detection component is fixed on the handle fixing seat.

[0027] Beneficial effects: The detection component is directly fixed on the handle mounting base, which can complete the magnetic polarity verification when the magnet is close to the assembly position, realizing the connection between the assembly and detection processes.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Specific embodiments of the automatic assembly device for automotive handle switch magnets: like Figure 1 and Figure 6 As shown, the automatic assembly device for automotive handle switch magnets includes a frame 1, a handle positioning and transfer mechanism 2, a magnet queuing and supply mechanism 3, a magnet assembly mechanism 4, a detection component 5, and a control unit 6.

[0032] The frame 1 serves as the supporting foundation for the entire device. The handle positioning and transfer mechanism 2 is slidably mounted on the upper part of the frame 1, used to carry the car handle 9 to be assembled and transfer it between the loading station and the handle assembly station. The magnet queuing and supply mechanism 3 is mounted on the frame 1, corresponding to the position of the handle assembly station, used to store stacked rows of magnets 7 and transport them row by row to the magnet assembly station. The magnet assembly mechanism 4 is fixed on the frame 1 with its working end facing the magnet assembly station, used to press a single magnet 7 at the magnet assembly station into the car handle 9 that has been transferred to its position. The detection component 5 is mounted on the handle positioning and transfer mechanism 2 and moves synchronously with the car handle 9, used to detect the magnetic polarity of the magnet 7 to be pressed into the car handle 9. The control unit 6 is installed inside the frame 1 and is communicatively connected to the handle positioning and transfer mechanism 2, the magnet queuing and supply mechanism 3, the magnet assembly mechanism 4, and the detection component 5, coordinating the control of each actuator to complete the assembly operation according to a preset sequence.

[0033] Specifically, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the frame 1 includes a base 101, a support plate 102, linear guide rails 103, a mounting base 104, a top plate 105, a front panel 106, a left side panel 107, a right side panel 108, a back panel 115, support feet 109, buttons 110, and handles 111. The base 101 is flat and horizontally arranged. Support feet 109 are fixed at the four bottom corners of the base 101, supporting the entire device and providing cushioning and shock absorption. Two linear guide rails 103 are fixed to the upper surface of the base 101, arranged parallel to each other in the left-right direction, and extending in the front-back direction. The support plate 102 is vertically fixed to the upper surface of the base 101, located to the side of the linear guide rails 103 and below the front panel 106. The mounting base 104 is fixedly connected to the upper part of the support plate 102. The left side panel 107, right side panel 108, and back panel 115 are vertically fixed to the sides and rear of the base 101, respectively. The top panel 105 covers the top of each side panel. The front panel 106 is installed between the left side panel 107 and the right side panel 108 and is arranged opposite to the back panel 115. All panels together form the outer shell of the equipment, providing protection for the internal components. Two buttons 110 are installed on the front surface of the base 101 for starting and stopping the equipment, respectively. Handles 111 are fixed to the left and right sides of the base 101 for easy movement and transport of the equipment by operators. An air purification device 113 is installed on the outer wall of the right side panel 108 for connecting to an external air source and purifying the input gas. Multiple solenoid valves 112 are installed on the inner side of the left side panel 107, connected to each pneumatic drive component via air circuits, for controlling the opening, closing, and reversing of the air circuits. Multiple indicator lights 114 are installed on the equipment panel 106 to indicate the equipment's operating status and fault alarms. For example... Figure 6 As shown, the control unit 6 is mounted on the right side panel 108 of the equipment, and the switching power supply is mounted on the rear side of the base 101, located inside the aforementioned outer housing. The switching power supply supplies power to all electrical components of the equipment, and the control unit 6 is a programmable logic controller used to execute the control logic of the entire assembly.

[0034] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the handle positioning and transfer mechanism 2 includes a movable base 201, a handle fixing base 202, a transfer drive component 203, and a position sensor 204. The bottom of the movable base 201 is slidably engaged with the linear guide rail 103, allowing it to slide back and forth along the extension direction of the linear guide rail 103. The transfer drive component 203 is a cylinder, connected to the aforementioned solenoid valve 112 via an air circuit. The transfer drive component 203 is fixedly mounted on the base 101, and its output end is drively connected to the movable base 201 to provide the driving force for the sliding of the movable base 201. The handle fixing base 202 is fixedly mounted on the upper surface of the movable base 201. The handle fixing base 202 is provided with a handle mounting position adapted to the shape of the car handle 9. The car handle 9 to be assembled can be embedded and fixed in the handle mounting position to ensure that the handle will not shift during the pressing process. The position sensor 204 is installed on the side of the handle fixing base 202, with its detection end facing the handle mounting position. It is used to detect whether the car handle 9 is installed in place and transmits the positioning signal to the control unit 6. The detection component 5 includes a magnetic pole detection sensor 51, which is fixedly installed on the handle mounting base 202. The detection end is directly opposite the magnet assembly position of the car handle 9, and can move synchronously with the car handle 9 to the handle assembly station to complete the polarity detection.

[0035] like Figure 9 and Figure 10 As shown, the magnet queuing and supply mechanism 3 includes a magnet placement seat 301, a magnet queuing seat 302, a magnet replenishment drive component 303, a first pressure plate 304, a second pressure plate 305, a magnetic adsorption component 306, and a first cylinder fixing seat 307.

[0036] like Figure 7 As shown, the first cylinder mounting base 307 is fixed to the base 101; the magnet supply drive unit 303 also uses a cylinder and is horizontally fixed to the first cylinder mounting base 307. The output rod of the magnet supply drive unit 303 extends towards the magnet placement base 301. The magnet placement base 301 and the magnet queuing base 302 are arranged at intervals, and both are fixed to the mounting base 104 by bolts. Figure 11 As shown, a magnet placement slot 3011 extending along the conveying direction of the magnet 7 is provided on the magnet placement seat 301. The width of the magnet placement slot 3011 is adapted to the width of a single row of magnets 7. The rows of magnets 7 are stacked in layers inside the magnet placement slot 3011.

[0037] like Figure 11As shown, a transition connection 3014 is integrally formed on the side of the magnet placement seat 301 facing the magnet queuing seat 302. The upper surface of the transition connection 3014 is flush with the bottom wall of the magnet placement groove 3011. A forward stop 3012 and a lateral stop 3013 are integrally formed on the magnet placement seat 301. The forward stop 3012 is located above the discharge end of the magnet placement groove 3011, and its vertical height is just enough for a single layer of magnets 7 to pass through. When the magnet replenishment drive 303 pushes the bottom layer of magnets 7, the forward stop 3012 can block all layers of magnets 7 above the bottom layer, so that only the bottom row of magnets 7 is pushed forward each time. The lateral stop 3013 is located on the side of the magnet placement groove 3011, and forms a lateral constraint on the stacked magnets 7 in a horizontal and perpendicular direction to the forward movement of the magnets 7, preventing the magnets 7 from shifting laterally or even collapsing during falling and conveying, ensuring that the layered stacked magnets 7 can fall and be replenished in an orderly manner.

[0038] like Figure 12 and Figure 13 As shown, the magnet queuing seat 302 has a magnet queuing groove 3021 extending along the magnet conveying direction. The magnet queuing groove 3021 is directly opposite the magnet placement groove 3011 and has the same width. The magnet assembly station is located at the end of the magnet queuing groove 3021. The aforementioned transition connection 3014 extends to a position near the inlet end of the magnet queuing groove 3021, which can prevent the magnet 7 from falling out of the gap between the magnet placement seat 301 and the magnet queuing seat 302 during the conveying process. The magnet queuing seat 302 has a magnetic suction groove 3023 in the extending direction of the magnet queuing groove 3021. The magnetic suction groove 3023 is located beside the magnet assembly station. A magnetic adsorption component 306 is positioned and installed in the magnetic suction groove 3023. The magnetic adsorption component 306 is a permanent magnet, and its magnetism is greater than that of the magnet 7 being assembled. Of course, the magnetic adsorption component 306 can also be an electromagnet. The depth of the magnetic groove 3023 is less than the height of the magnetic adsorption component 306, allowing the magnetic force of the magnetic adsorption component 306 to effectively act on the magnets 7 in the magnet queuing groove 3021. The magnetic groove 3023 and the magnet queuing groove 3021 are separated by a baffle 3024. The side wall of the baffle 3024 forms a reference surface for the magnets 7 to rest on. The magnetic adsorption component 306 can attract and pull the entire row of magnets 7 in the magnet queuing groove 3021 to the magnet assembly station, so that the frontmost magnet 7 is attached to the outer side wall of the baffle 3024, completing the precise positioning of the magnets 7.

[0039] like Figure 10As shown, the first pressure plate 304 is detachably connected to the upper part of the magnet queuing seat 302 by bolts, correspondingly covering the magnet assembly station. The first pressure plate 304 is used to limit and constrain the magnet 7 at the magnet assembly station in the vertical direction, preventing the magnet 7 from moving upward and falling out of the magnet queuing slot 3021 during the pushing process; at the same time, the lower surface of the first pressure plate 304 can press the magnetic adsorption component 306 downward to prevent the magnetic adsorption component 306 from shifting during the operation of the equipment, and ensure the stability of the adsorption positioning.

[0040] The second pressure plate 305 is detachably connected to the upper part of the magnet queuing seat 302 by bolts, correspondingly covering the upper area of ​​the magnet queuing groove 3021. The second pressure plate 305 has an oblong hole extending along the width direction of the magnet 7. Bolts pass through the oblong hole to fix the second pressure plate 305. The installation position of the second pressure plate 305 can be adjusted through the oblong hole to accommodate magnets 7 of different widths. The second pressure plate 305 is used to limit the movement of the magnet 7 in the magnet queuing groove 3021 in the vertical direction, preventing the magnet 7 from jumping up and down during transport and ensuring that the magnet 7 moves smoothly along the magnet queuing groove 3021.

[0041] like Figure 8 As shown, the magnetic sensor 8 is positioned between the magnet placement seat 301 and the magnet queuing seat 302, with its detection end facing the mating gap between the two. The magnetic sensor 8 is communicatively connected to the control unit 6 and is used to detect the position status of the magnets 7 in the magnet queuing slot 3021 in real time, and to feed back the inventory information of the magnets 7 to the control unit 6.

[0042] like Figure 7 , Figure 8 and Figure 9As shown, the magnet assembly mechanism 4 includes a magnet mounting drive 401, a mounting pin 402, and a second cylinder mounting base 403. The second cylinder mounting base 403 is fixed on the mounting base 104. The magnet mounting drive 401 is a cylinder connected to a solenoid valve 112 via an air passage. The magnet mounting drive 401 is horizontally fixed on the second cylinder mounting base 403, and its output rod extends towards the magnet assembly station. The mounting pin 402 is coaxially connected to the end of the output rod of the magnet mounting drive 401. A guide channel 3022, perpendicularly penetrating the magnet queuing slot 3021, is provided on the magnet queuing base 302 at the position corresponding to the magnet assembly station. The width of the guide channel 3022 is adapted to the outer diameter of the mounting pin 402, allowing the mounting pin 402 to move along the guide channel 3022. One side wall of the guide channel 3022 is coplanar with the outer side wall of the stop 3024, ensuring that the positioning reference of the magnet 7 is consistent with the pressing guide reference, thus guaranteeing the accuracy of the pressing position. When the magnet mounting drive 401 extends, it drives the mounting pin 402 to move along the guide channel 3022, pushing the individual magnet 7 at the magnet assembly station out of the magnet queuing slot 3021 and pressing it into the corresponding position of the car handle 9.

[0043] The detection component 5 includes a magnetic pole detection sensor 51, which is fixed on the handle mounting base 202. The detection end faces the magnet mounting hole of the car handle 9. When the magnet 7 is pressed into place, the magnetic pole detection sensor 51 can detect the magnetic field polarity of the magnet 7, determine whether the installation direction of the magnet 7 is correct, and transmit the detection result to the control unit 6.

[0044] The working process of the automatic assembly device for automotive handle switch magnets of the present invention is as follows: Before using the equipment, connect the external power supply to the equipment's power interface and connect the external air source to the air purification device 113 to complete the air and power supply preparation. The operator presses the start button 110, and the equipment powers on and initializes. At this time, the transfer drive 203 is fully extended, causing the moving seat 201 to stop at the outer loading position, facilitating loading by the operator. The operator inserts the car handle 9 to be assembled into the handle mounting position of the handle fixing seat 202. After the position sensor 204 detects that the car handle 9 is installed in place, it sends a positioning signal to the control unit 6. Upon receiving the handle positioning signal, the control unit 6 controls the transfer drive 203 to fully retract, causing the moving seat 201 to move inward along the linear guide rail 103, transferring the car handle 9 to the handle assembly station and stopping, ensuring that the magnet mounting hole on the car handle 9 is aligned with the output position of the magnet assembly station.

[0045] The supply of magnets 7 is carried out simultaneously. Rows of magnets 7, stacked in layers, are pre-placed in the magnet placement slot 3011. The magnet supply drive 303 continuously pushes forward with a set thrust, pushing the bottom row of magnets 7 forward. The upper layers of magnets 7 are blocked by the forward stop 3012 and remain in place. The pushed row of magnets 7 enters the magnet queuing slot 3021 via the transition connection 3014. The magnets 7 entering the magnet queuing slot 3021 are attracted by the magnetic force of the magnetic adsorption component 306 and move forward along the slot to the magnet assembly station. The foremost magnet 7 is positioned against the outer wall of the baffle 3024. When the entire row of magnets 7 has completely entered the magnet queuing slot 3021 and reached the designated position, the magnetic sensor 8 detects the presence signal of the magnets 7 and sends it back to the control unit 6. The control unit 6 controls the magnet supply drive 303 to retract to its initial position. The upper layer of magnets in the magnet placement slot 3011 falls to the bottom layer under gravity, awaiting the next supply push.

[0046] Control unit 6 sends an action signal to magnet mounting drive 401, causing it to extend and push mounting pin 402 forward along guide channel 3022, pushing the individual magnet 7 at the magnet assembly station forward and precisely pressing it into the preset mounting hole of the car handle 9. After the pressing action is completed, magnetic pole detection sensor 51 detects the polarity of the inserted magnet 7. If the detected magnetic pole polarity meets the preset requirements, it sends a pass signal to control unit 6. Control unit 6 then controls magnet mounting drive 401 to retract, pushing mounting pin 402 back to its initial position. Subsequently, control unit 6 controls transfer drive 203 to extend fully, pushing moving seat 201 back to loading position along linear guide rail 103. The operator removes the assembled car handle 9 and replaces it with a new handle to be assembled, entering the next assembly cycle. If magnetic pole detection sensor 51 detects an abnormal magnetic pole polarity, control unit 6 controls the equipment to maintain its current state and triggers indicator light 114 to issue an abnormality alarm, awaiting operator intervention to prevent unqualified products from flowing into the next process.

[0047] In continuous assembly, after each magnet 7 is pressed in, the mounting pin 402 retracts, and the magnetic adsorption component 306 attracts the next magnet 7, moving it forward to the stop 3024 to prepare for the next pressing. This process is repeated to assemble the entire row of magnets 7 one by one. The control unit 6 records the number of magnets 7 installed. When the recorded number is an integer multiple of the number of magnets 7 in each row, it indicates that the current row of magnets 7 has been fully assembled. At this point, the control unit 6 controls the magnet replenishment drive component 303 to extend again, pushing a new row of magnets 7 from the magnet placement slot 3011 into the magnet queuing slot 3021, completing automatic replenishment. This cycle achieves continuous automatic supply and assembly of magnets 7, eliminating the need for frequent manual replenishment and disassembly.

[0048] In the above embodiments, the detection component 5 is installed on the handle mounting base 202 and moves synchronously with the handle. In other embodiments, the detection component 5 can also be installed on the frame 1, with the magnetic pole detection sensor 51 correspondingly set on the side of the handle assembly station. After the car handle 9 is moved to the handle assembly station, the polarity of the magnet 7 pressed into the car handle 9 is directly detected without the need for reciprocating movement with the car handle 9.

[0049] In the above embodiments, the magnet supply drive 303, the magnet mounting drive 401, and the transfer drive 203 are all in the form of cylinders. In other embodiments, the magnet supply drive 303, the magnet mounting drive 401, and the transfer drive 203 may also be linear drive components such as electric push rods or hydraulic cylinders.

[0050] In the above embodiments, the forward stop 3012 and the side stop 3013 are integrally formed with the magnet placement base 301. In other embodiments, the forward stop 3012 and the side stop 3013 can also be separate baffle structures, which are fixed to the upper and side of the discharge end of the magnet placement base 301 by screws, respectively. The installation position of the baffles can be adjusted according to the thickness and width of the magnet 7 to accommodate the stacking and distributing needs of magnets of more specifications.

[0051] In the above embodiments, the detection component 5 relies solely on the magnetic pole detection sensor 51 to determine polarity. In other embodiments, the detection component 5 can also be combined with a photoelectric auxiliary detection module. The photoelectric sensor first determines whether there is a magnet 7 inside the hole, and then the magnetic pole detection sensor 51 verifies the magnetic pole. The dual signals are used for joint determination to accurately distinguish between two types of faults: missing parts and reversed polarity, making the fault differentiation clearer.

[0052] While various embodiments of the invention have been shown and described in this specification, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and essence of the invention.
