Description

Technical Field

[0001] This utility model belongs to the field of automotive electronic product manufacturing and testing, specifically relating to an assembly and testing device for a rotary switch. Background Technology

[0002] As a core control component in the automotive cabin, the rotary switch integrates key functions such as rearview mirror angle adjustment, heating and defogging, electric folding, and anti-glare. A rotary switch typically includes an upper cover assembly 1001 and a base assembly 1002. The upper cover assembly 1001 mainly consists of a knob cap 100, an upper cover 200, a rotor assembly 300, a transmission lever 400, a top pin 500, and a top pin spring. The upper cover 200 forms an assembly cavity 201 with an open lower end. A track seat 202 is inserted into the cavity, and the rotor assembly 300 is installed inside the track seat 202. The specific structure of the rotor assembly 300 has been disclosed in patent CN118682463A, and it mainly includes a rotor seat 301 and an upper spring 300. 2. The rotor seat 301 has slots on its bottom and side walls, including a contact piece 303, a side spring 304, and a positioning pin 305. A spring 302 and a contact piece 303 are installed in the bottom slot, and a side spring 304 and a positioning pin 305 are installed in the side wall slot. The positioning pin 305 abuts against the track seat 202 under the elastic force of the side spring 304. A vertical through-hole is provided in the center of the rotor seat 301, and a corresponding insertion hole is provided on the upper end of the top cover 200. The lower end of the transmission lever 400 has an insertion channel, and a top pin spring and a top pin 500 are sequentially installed inside this channel. During assembly, the upper end of the transmission lever passes sequentially through the mounting hole of the rotor seat and the insertion hole of the upper cover, and inserts with the knob cap to form a linkage structure; the base assembly 1002 mainly includes a base 700, a lever 800, a circuit board 900, and a pin group 1000. The lower end 700 of the base is provided with a pin compartment 701, and the side of the pin compartment has an opening. One end of the pin group 1000 is connected to the circuit board 900, and the other end extends into the pin compartment 701. The pin group is the signal and power transmission interface; when the upper cover assembly and the base assembly are assembled, the contacts of the upper cover assembly and the circuit of the base assembly are connected. The top pin of the upper cover assembly passes through the circuit board hole in the base assembly and is inserted into the positioning hole of the lever. When the knob cap is rotated, the transmission lever can be driven to rotate synchronously, thereby driving the rotor assembly to rotate along the inner side of the track seat. The contact piece moves in a circle with the rotor assembly. By switching the contact piece with different conductive points on the circuit board, the gear or function mode can be adjusted. When the knob cap is turned, the transmission lever can swing relative to the rotor assembly, and the top pin drives the lever to slide. By switching the contact piece with different conductive points on the circuit board, the gear or function mode can be adjusted.

[0003] The top cover assembly and the base assembly are connected and fixed together by multiple snap-fits arranged circumferentially. The snap-fits are usually distributed in multiple directions, such as the left and right sides or the front and back sides, and pressure needs to be applied from multiple directions to fully lock the snap-fits. In the prior art, the assembly of snap-fits usually relies on manual operation or single-station press-fit equipment. Manual operation has problems such as low efficiency, incomplete pressing, and easy damage to snap-fits. The multi-position function (L position, R position, H position, A position, 0 position) testing of this type of switch mainly relies on manual operation: the tester needs to manually hold the knob cap, rotate it one by one to switch between positions, and adjust it by moving it back, forth, left, and right. The resistance value of the knob switch is measured by tools such as a multimeter. This has problems such as low testing efficiency, large human operation error, and the inconsistent force when manually moving the knob, making it difficult to ensure that the operation is in place every time, which easily leads to misjudgment and omission, affecting the yield of products leaving the factory. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art by providing an assembly and testing device for a rotary switch, which can automatically complete the press-fit assembly of the rotary switch top cover assembly and the base assembly, as well as the automatic testing of each position function.

[0005] The technical solution of this utility model is: an assembly and testing device for a rotary switch, comprising a rotary switch pressing device and a rotary switch testing device; The rotary switch pressing device includes a first frame, an indexing plate unit mounted on the first frame, a top cover assembly storage and feeding unit, a base assembly storage and feeding unit, a rotary switch flipping and unloading unit, a rotary switch track conveying unit, and a rotary switch 0 return unit. The indexing plate unit includes a fixed base and a rotating indexing plate that is rotatably arranged. Several sets of loading devices are provided on the rotating indexing plate along the circumferential direction. Each set of loading devices has a positioning groove for accommodating the inverted cover assembly. The upper cover assembly storage and loading unit is used to load the inverted upper cover assembly into the loading container of the rotating indexing plate; The base assembly storage and loading unit is used to load the inverted base assembly onto the assembly loading device, and to press and fasten the base assembly onto the top cover assembly to complete the rotary switch assembly. The circuit board of the base assembly contacts the contact piece of the top cover assembly, and the top pin of the top cover assembly passes through the board hole of the circuit board of the base assembly and is inserted into the positioning hole of the lever. The rotary switch flipping and unloading unit is used to take the assembled inverted rotary switch out of the loading container of the indexing plate unit, flip it to the upright state, and then transfer it to the rotary switch track conveying unit. The rotary switch track conveying unit includes a feeding conveying track and a plurality of rotary switch carriers that are sequentially conveyed by the feeding conveying track; The knob reset unit is used to rotate the knob cap of the upright rotary switch mounted on the rotary switch carrier on the feeding conveyor track to the 0 position. The rotary switch testing device includes a second frame and a turntable unit mounted on the second frame. The turntable unit has several carrier testing units arranged circumferentially on it. The carrier testing units are used to fix the rotary switch to be tested and are connected to a resistance tester. The turntable unit is used to drive each carrier testing unit to rotate synchronously circumferentially. The second frame has a loading and unloading unit, a knob rotation unit, and a knob toggle unit arranged along the outer periphery of the turntable unit. The loading and unloading unit is used to transfer the rotary switch in the upright position and at position 0 to the carrier detection unit, and at the same time remove the rotary switch that has completed the detection from the carrier detection unit. The knob rotation unit is used to rotate the knob cap of the knob switch to the corresponding position, and at the same time, the resistance data of the knob switch at the current position is collected by the resistance tester. The rotary toggle unit is used to toggle the knob cap of the rotary switch, and the resistance value of the switch in the toggle direction is detected by a resistance tester.

[0006] By adopting the above technical solution, the feeding and assembly, posture adjustment and transfer, gear reset and electrical performance testing of the rotary switch are integrated to achieve fully automated operation.

[0007] The indexing unit, in conjunction with multiple loading devices, sequentially undertakes the loading of the top cover assembly and the pressing of the base assembly along the circumference. It can cooperate in an orderly manner with each loading and processing station, and complete the assembly steps station by station under the intermittent rotation of the indexing unit. The upper cover assembly storage and feeding unit realizes the automated batch storage and feeding of the upper cover assembly; the base assembly material tray storage equipment realizes the automated storage and feeding of the base assembly. The upper cover assembly and the base assembly adopt an inverted storage and positioning, which, together with the inverted placement and positioning of the assembly loading device, facilitates the pressing of the base assembly onto the upper cover assembly from top to bottom, ensuring that the internal structure of the switch is assembled in place and that the mechanical connection and electrical contact are reliable. The assembled rotary switch is then removed by the rotary switch flipping and unloading unit, and its posture is adjusted so that the rotary switch changes from an inverted state to an upright state, adapting to the positioning structure of the rotary switch carrier. This facilitates the gripping operation of the knob cap during subsequent knob zeroing and testing operations. The rotary switches that have undergone zeroing ensure that the initial position of each switch to be tested is consistent, providing a unified benchmark for subsequent step-by-step testing and avoiding test data errors caused by initial position deviations. The turntable unit drives the carrier testing unit carrying the switch through different testing stations in sequence, and works with the knob rotation unit and knob toggle unit to complete the automatic testing of each function level. No manual intervention is required throughout the process, effectively improving testing accuracy and efficiency.

[0008] A further feature of this invention is that the upper cover assembly storage and feeding unit includes a first material tray storage device and an upper cover assembly feeding mechanism. The first material tray storage device is used to store a first material tray containing the upper cover assembly. The surface of the first material tray has a plurality of upper cover assembly slots for accommodating the upper cover assembly in an inverted state. The upper cover assembly feeding mechanism is used to remove the upper cover assembly in an inverted state from the first material tray and transfer it to the positioning slot of the corresponding loading device of the indexing plate unit. The base assembly loading mechanism includes a base clamping and pressing device and a base side pressing device; The base clamping and pressing device includes a first gripper, a first driving member that drives the opening and closing of the first gripper, and a displacement driving module that drives the first gripper to move. The first driving member is connected to the power output end of the displacement driving module. The first gripper is used to clamp the base assembly in an inverted state on the second material tray. The displacement driving module drives the first gripper to move horizontally to directly above the assembly of the loading device cover, and drives the first gripper to press down and fasten the base assembly onto the cover assembly. The base side pressing device includes a first slider and a second slider that are linearly slidable in the same direction relative to a fixed base. The base side pressing device also includes two driving devices that drive the first slider and the second slider to move respectively. The driving devices are relatively fixed on the fixed base. The first slider has two inclined grooves that are inclined to its own direction of movement. The two inclined grooves are symmetrically arranged with respect to the direction of movement of the first slider. A transmission pin is slidably arranged in each of the two inclined grooves. The device also includes two pressure rods, each of which is rotatably connected to the transmission pin. The second slider has guide grooves on both sides. The pressure rods are arranged through a guide groove. When the first slider and the second slider move together, the pressure rods move closer to or away from the assembly loading fixture at the corresponding assembly station. When the first slider and the second slider move relative to each other, the ends of the two pressure rods that are closer to the assembly loading fixture move closer to or away from each other.

[0009] With the above-mentioned further configuration, the base clamping and pressing device first applies initial pressure to the base assembly, pre-fitting the base assembly into the corresponding position of the upper cover assembly. This allows the various circumferential buckles of the base to initially engage with the pre-set slots of the upper cover, completing the pre-assembly positioning and ensuring the accurate relative position of the base and the upper cover, preparing for subsequent side-pressing and locking. Subsequently, the base side-pressing device operates, and through the coordinated action of the first and second sliders, it drives the two pressure rods to move synchronously towards the assembly loading device. The working ends of the two pressure rods move closer to each other along the inclined groove guide, applying uniform side pressure synchronously from both sides of the base assembly to fully press and lock the pre-fitted buckles.

[0010] A further feature of this invention is that the base assembly storage and feeding unit includes a second material tray storage device and a base assembly feeding mechanism. The second material tray storage device is used to store a second material tray containing the base assembly. The surface of the second material tray is provided with a plurality of base assembly material slots for accommodating the inverted base assembly. The base assembly feeding mechanism is used to remove the inverted base assembly from the second material tray and press it onto the upper cover assembly of the assembly loading device, thereby completing the snap-fit ​​installation of the base and the upper cover. The base assembly loading mechanism also includes a rotor straightening assembly. The rotor straightening assembly includes a second gripper for holding the knob cap of the top cover assembly, a second drive member for driving the second gripper to open and close, and a third drive member. The second drive member is fixed to the power output end of the third drive member. The second gripper is driven by the third drive member to move up and down. The bottom of the positioning groove of the assembly loading device is provided with a through hole for the knob cap of the top cover assembly to be exposed. The rotating indexing plate is provided with a clearance groove that aligns with the through hole. The rotor straightening assembly is located below the rotating indexing plate. The second gripper of the rotor straightening assembly extends into the bottom of the positioning groove of the assembly loading device through the clearance groove and holds the knob cap and pulls it downward, so that the rotor assembly is kept in a flat and horizontal assembly state.

[0011] With the above-mentioned further configuration, before assembling the base assembly, the spring force of the rotor assembly will cause the rotor seat to tilt and lift up, making it impossible to maintain a horizontal posture. Therefore, the rotor assembly must be pre-pressed before the snap-fit ​​installation. In this structure, after the rotor assembly in the upper cover is pressed into a horizontal state, the second claw of the rotor straightening component extends into the bottom of the positioning groove of the assembly loading device through the clearance groove, and pulls the clamping knob cap downward to maintain the horizontal posture of the rotor assembly and prevent it from tilting up. This avoids the internal parts getting stuck when the base assembly is pressed down due to the rotor tilting, ensuring smooth cooperation of the internal transmission structure after the base and upper cover are assembled, and reducing the risk of parts getting stuck and damaged during snap-fit ​​installation.

[0012] A further feature of this invention is that the rotary switch flipping and unloading unit includes a rotary switch conveying mechanism and a rotary switch flipping mechanism; the rotary switch flipping mechanism includes a flipping rotation module and a flipping gripper, the flipping gripper is fixed to the power output end of the flipping rotation module, the flipping gripper is used to hold the inverted rotary switch, and the flipping rotation module is used to drive the flipping gripper to rotate 180° around the horizontal axis, so that the inverted rotary switch is converted to the upright state; The rotary switch handling mechanism includes a vertical lifting module, a horizontal translation module, and a double-clamp assembly. The double-clamp assembly includes a first workpiece clamp and a second workpiece clamp arranged side by side. The vertical lifting module is installed at the power output end of the horizontal translation module. The first workpiece clamp and the second workpiece clamp are driven to the power output end of the vertical lifting module. The vertical lifting module is used to drive the first workpiece clamp and the second workpiece clamp to move vertically. The horizontal translation module is used to drive the first workpiece clamp and the second workpiece clamp to slide along the unloading conveyor track. The first workpiece clamp is used to take out the assembled inverted rotary switch from the assembly loading device of the indexing plate unit and place it on the rotary switch flipping mechanism to complete the flipping. The second workpiece clamp grabs the flipped upright rotary switch and moves it to the rotary switch carrier on the unloading conveyor track. The second workpiece clamp can also be driven by the horizontal rotation module to rotate circumferentially around the vertical axis, thereby adjusting the angle of the upright rotary switch to align with the corresponding slot of the rotary switch carrier.

[0013] With the above-mentioned further settings, the flipping gripper stably holds the inverted knob switch, preventing the workpiece from falling off or shifting during the flipping process. The flipping rotation module drives the gripper and the entire workpiece to complete a 180° rotation around the horizontal axis, accurately realizing the workpiece's posture switching from inverted to upright, perfectly matching the working posture requirements of the front and rear workstations, and ensuring a consistent flipping angle each time; The combination of the vertical lifting module and the horizontal translation module enables the dual-gripper assembly to have lifting and horizontal sliding capabilities, allowing for workpiece transfer across workstations. The first workpiece gripper is specifically designed to pick up assembled workpieces and feed them to the flipping mechanism. The second workpiece gripper is responsible for grabbing the flipped workpiece and transferring it to the rotary switch carrier. The dual grippers work together to achieve continuous operation of picking up, feeding, and transferring workpieces. The second workpiece gripper is equipped with a horizontal rotation module, which can rotate the workpiece around the vertical axis to adjust the angle, adapting to the slot positioning requirements of the rotary switch carrier. This solves the problem of workpieces not being able to be accurately positioned after the angle shifts after flipping, ensuring that the workpiece is placed stably and accurately on the carrier of the conveyor track.

[0014] A further feature of this invention is as follows: the knob reset unit includes a switch positioning mechanism and a knob rotation reset mechanism; the switch positioning mechanism includes a pair of positioning plates and a positioning plate driving module, the positioning plate driving module is used to drive the pair of positioning plates to open and close relative to each other, and when the pair of positioning plates are close together, they clamp the outer wall of the upper cover of the limit knob switch; the knob rotation reset mechanism includes a rotating clamping member, a first rotating driving member and a first lifting driving member, the rotating clamping member is connected to the power output end of the first rotating driving member, the first rotating driving member is connected to the power output end of the first lifting driving member, the rotating clamping member is used to clamp the knob cap of the knob switch, and the first rotating driving member is used to drive the rotating clamping member to rotate circumferentially around the vertical axis, so as to drive the knob cap to rotate to the initial 0 position.

[0015] With the above-mentioned further configuration, the positioning plate drive module drives a pair of positioning plates to open and close relative to each other. After the workpiece is in place, the positioning plates move closer together to clamp the outer wall of the switch cover, limiting the entire switch housing. The rotating clamping component and the knob cap are matched and engaged. The first rotating drive component provides circumferential rotational power, driving the knob cap to rotate to the initial 0 position, which can complete the zeroing of the position, unify the initial position state of all workpieces to be tested, and eliminate the interference caused by the inconsistency of the initial position on the subsequent resistance detection and toggle detection results.

[0016] A further feature of this invention is as follows: the carrier detection unit includes a carrier base, the upper surface of which is provided with a positioning cavity for positioning a rotary switch, and the bottom of the positioning cavity is provided with a clearance opening for the pin compartment at the lower end of the base to be inserted. The carrier base is equipped with a detection component, which includes a detection pin holder and a second driving component for driving the detection pin holder to slide. The detection pin holder is provided with a probe group connected to a resistance tester by a cable. The probe group can be slidably inserted or pushed out of the pin compartment opening, and the probe group contacts the pin group to achieve electrical conduction.

[0017] With the above-mentioned further configuration, after the rotary switch is positioned in the positioning cavity, the pin compartment at the lower end of the base extends downward from the clearance opening. The detection component relies on the second driving component to drive the detection pin seat and probe group to slide as a whole, so that the probe group can be smoothly inserted into the pin compartment and reliably contact the internal pins, realizing the electrical connection between the rotary switch and the resistance tester. This structure can achieve precise docking between the probe and the pin, stable contact, and is not prone to problems such as loose connection or disconnection, and can continuously and stably transmit electrical signals.

[0018] A further feature of this invention is as follows: The knob rotation unit includes a knob gripper, a second rotation drive, and a second lifting drive. The knob gripper is connected to the power output end of the second rotation drive, which is also connected to the power output end of the second lifting drive. The knob gripper is used to hold the knob cap, and the second rotation drive is used to drive the knob gripper to rotate circumferentially around the vertical axis, thereby causing the knob cap to switch to each gear position sequentially. The knob actuation unit includes a knob hook, a horizontal sliding drive module, and a second vertical sliding drive module. The knob hook is used to fit the knob cap, the second vertical sliding drive module is used to drive the knob hook to move up and down along the Z-axis, and the horizontal sliding drive module is used to drive the knob hook to slide the knob cap horizontally, thereby actuating the knob cap.

[0019] With the further configuration described above, the knob rotation unit uses a first vertical sliding drive module to raise and lower the knob gripper, completing the docking and separation of the gripper and the knob cap. The gripper can drive the knob cap to rotate 360° circumferentially, enabling the knob to be switched to various working positions sequentially. Combined with a resistance tester, this allows for full-position static resistance testing, comprehensively verifying the electrical conductivity performance of the switch at different positions. The knob toggle unit relies on a second vertical sliding drive module to raise and lower the hook assembly for alignment. A horizontal sliding drive module drives the hook assembly to move horizontally, simulating the actual use condition of manually toggling the knob, and performing dynamic toggle testing on the switch. These two units respectively perform position rotation detection and toggle condition detection, comprehensively simulating actual switch usage scenarios, fully verifying the operating feel of the knob switch, and improving the comprehensiveness of product testing.

Detailed Implementation

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 4-16 As shown, the present invention provides an assembly and testing device for a rotary switch, comprising a rotary switch pressing device 1 and a rotary switch testing device 2. The rotary switch pressing device 1 includes a first frame 11, an indexing plate unit 12 mounted on the first frame 11, a top cover assembly storage and feeding unit 13, a base assembly storage and feeding unit 14, a rotary switch flipping and unloading unit 15, a rotary switch track conveying unit 16, and a rotary switch 0 return unit 17. The indexing unit 12 includes a fixed base 121 and a rotating indexing disk 122 that is rotatably arranged. The rotating indexing disk can be driven by a stepper motor to achieve intermittent indexing rotation. The rotating indexing disk 122 is provided with a plurality of loading devices 123 along the circumferential direction. The loading devices 123 have positioning grooves for accommodating the inverted cover assembly. The upper cover assembly storage and loading unit 13 is used to load the inverted upper cover assembly into the loading fixture of the rotating indexing plate. The upper cover assembly storage and loading unit 13 includes a first material tray storage device 131 and an upper cover assembly loading mechanism 132. The material tray storage device is a conventional design and can be used to store the first material tray 1311 containing the upper cover assembly. The surface of the first material tray has several upper cover assembly material slots 13111 for accommodating the inverted upper cover assembly. The shape of the upper cover assembly material slots is adapted to the bottom contour of the inverted upper cover to stably support and store the workpiece. The upper cover assembly loading mechanism 132 is a conventional design and uses pneumatic grippers in conjunction with multi-directional sliding drive components to achieve displacement on the X, Y, and Z axes. It is used to take out the inverted upper cover assembly from the first material tray 1311 and transfer it to the positioning slot of the corresponding loading fixture 123 of the indexing plate unit. The base assembly storage and loading unit 14 is used to load the inverted base assembly onto the assembly loading device, and to press and fasten the base assembly to the top cover assembly to complete the rotary switch assembly. The circuit board of the base assembly contacts the contact piece of the top cover assembly. The top pin of the top cover assembly passes through the board hole of the base assembly circuit board and is inserted into the positioning hole of the lever. The base assembly storage and loading unit 14 includes a second material tray storage device 141 and a base assembly loading mechanism 142. The second material tray storage... The device 141 is also a conventional design and can be used to store the second material tray 1411 containing the base assembly. The surface of the second material tray has a plurality of base assembly material slots 14111 for accommodating the base assembly in the inverted state. The shape of the base assembly material slots is adapted to the bottom contour of the inverted base. The base assembly loading mechanism 142 is used to take out the inverted base assembly from the second material tray 1411 and press it onto the upper cover assembly of the assembly loading device 123 to complete the snap-fit ​​installation of the base and the upper cover. The rotary switch flipping and unloading unit 15 is used to take the assembled inverted rotary switch out of the loading container 123 of the indexing plate unit 12 and flip it to the upright state, and then transfer it to the rotary switch track conveying unit 16. The rotary switch track conveying unit 16 includes a feeding conveying track 161 and a plurality of rotary switch carriers 162 that are sequentially conveyed by the feeding conveying track. The feeding conveying track is a conventional chain or belt conveying structure that can drive the rotary switch carriers and upright rotary switches to be conveyed. The knob reset unit 17 is used to rotate the knob cap of the upright rotary switch mounted on the rotary switch carrier 162 on the unloading conveyor track 161 to the 0 position. The specific working principle is as follows: The first tray storage equipment of the upper cover assembly storage and feeding unit pre-stores the first tray containing the inverted upper cover assemblies in batches. The upper cover assembly feeding mechanism sequentially takes out the inverted upper cover assemblies from the first tray and transfers them to the positioning slot of the assembly loading device at the corresponding station of the rotating indexing plate, completing the automatic feeding and positioning of the upper cover assembly. The rotating indexing plate drives the assembly loading device containing the upper cover assembly to rotate intermittently. Then, the base assembly feeding mechanism of the base assembly storage and feeding unit clamps the inverted base assembly from the second tray and presses the base assembly onto the upper cover assembly, completing the process. The base and top cover are assembled with snap fasteners. At this time, the circuit board of the base assembly and the contact piece of the top cover assembly are aligned and in contact. The top pin of the top cover assembly passes through the board hole of the base circuit board and is inserted into the positioning hole of the lever, completing the assembly of the rotary switch body. Subsequently, the assembled inverted rotary switch is taken out from the indexing plate by the rotary switch flipping and unloading unit, flipped to the upright position, and transferred to the rotary switch carrier of the rotary switch track conveying unit. It is conveyed forward along the unloading and conveying track. When it passes the rotary zeroing unit, the rotary zeroing unit rotates the knob cap back to the 0 position. After the assembly is completed, it is sent to the rotary switch testing device.

[0024] Specifically, the base assembly loading mechanism 142 includes a base clamping and pressing device 1421 and a base side pressing device 1422. The base clamping and pressing device 1421 includes a first gripper 14211, a first driving member 14212 that drives the opening and closing of the first gripper 14211, and a displacement driving module 14213 that drives the first gripper 14211 to move. The first driving member 14212 is connected to the power output end of the displacement driving module 14213. The first gripper 14211 is used to clamp the base assembly in an inverted state on the second tray 1411. The displacement driving module 14213 drives the first gripper to move horizontally to directly above the upper cover assembly of the assembly loading device 123 and drives the first gripper to move horizontally. The base assembly is pressed down and fastened to the upper cover assembly. The displacement drive module is a conventional design, including an X-axis module, a Y-axis module, and a Z-axis module, which drives the first gripper to move in multiple directions. The X-axis module includes an X-axis drive motor and an X-axis lead screw and nut assembly mounted on the first frame. The nut of the X-axis lead screw and nut assembly is fixedly provided with an X-axis slider. The X-axis module is mounted on the first frame, and the X-axis drive motor drives the X-axis slider to reciprocate linearly along the X-axis direction. Alternatively, the X-axis module can directly use a linear drive cylinder or electric cylinder. The Y-axis and Z-axis modules have the same structure and principle as the X-axis module, and the drive method can be selected according to the actual assembly space and drive requirements. Displacement on the X, Y, and Z axes can be achieved. The base side pressing device 1422 includes a first slider 14221 and a second slider 14222 that are linearly slidable relative to the fixed base 121 in the same direction. The base side pressing device 14222 also includes driving devices 14223 that drive the first slider 14221 and the second slider 14222 to move respectively. The two driving devices 14223 are fixedly mounted on the fixed base 121, and their output ends are fixedly connected to the first slider and the second slider respectively, for driving the two sliders to move in the same horizontal linear direction. The first slider 14221 is provided with two inclined grooves 142211 that are inclined to its own direction of movement. The two inclined grooves 142211 are symmetrically arranged with respect to the direction of movement of the first slider 14221. The structure is shaped like the number "8". Two inclined grooves 142211 each contain a transmission pin that slides relative to each other. It also includes two pressure rods 14224, each rotatably connected to a transmission pin. The second slider 14222 has guide grooves 142221 on both sides, with openings on the outer sides of the guide grooves. Each pressure rod 14224 passes through a corresponding guide groove 142221. When the first slider 14221 and the second slider 14222 move together, the pressure rod 14224 moves closer to or further away from the assembly loading fixture 123 at the corresponding assembly station. When the first slider 14221 and the second slider 14222 move relative to each other, the ends of the two pressure rods 14224 that are closer to the assembly loading fixture 123 move closer to or further away from each other.

[0025] The base assembly loading mechanism 142 further includes a rotor straightening assembly 143. The rotor straightening assembly 143 includes a second gripper 1431 for holding the knob cap of the upper cover assembly, a second drive member 1432 for driving the second gripper 1431 to open and close, and a third drive member 1433. The third drive member is a linear sliding cylinder. The second drive member 1432 is fixedly connected to the power output end of the third drive member 1433. The second gripper 1431 is driven by the third drive member 1433. The drive lifts and slides; the bottom of the positioning groove of the assembly loading device 123 is provided with a through hole for the knob cap of the upper cover assembly to be exposed, and the rotating indexing plate 122 is provided with a clearance through groove that aligns with the through hole; the rotor straightening assembly 143 is located below the rotating indexing plate 122, and the second gripper 1431 of the rotor straightening assembly 143 extends into the bottom of the positioning groove of the assembly loading device 123 through the clearance through groove, and clamps the knob cap and pulls it downward, so that the rotor assembly is kept in a horizontal assembly state after pre-pressing and flattening.

[0026] When in use, the rotor assembly in the top cover can be pressed down to a horizontal state by the matching pressing component or manually to prevent the rotor assembly from tilting up. Then, the third drive component of the rotor straightening component drives the second gripper to move upward. Under the action of the second drive component, the second gripper opens and closes to hold the knob cap from the bottom of the top cover. Then, the third drive component drives the second gripper to pull downward, so that the tilted top cover rotor assembly is kept in a horizontal and straight state by pulling down. Afterwards, the first gripper moves the base assembly above the top cover assembly, aligns it, and presses it down to complete the initial snap-fit. The rotating indexing plate drives the assembly loading device to rotate to the next station. Then, the drive device drives the first and second sliders to move. When the first and second sliders move closer to each other, the inclined groove generates a lateral force on the transmission pin, causing the two pressure rods to move closer to each other and press laterally against both sides of the joint position between the base assembly and the top cover assembly. Then, under the action of the drive device, the first and second sliders move synchronously towards the assembly station. After the two pressure rods are synchronously driven into place, the first and second sliders move relative to each other. Through the cooperation of the inclined groove and the transmission pin, the lower ends of the two pressure rods move closer to each other synchronously, applying uniform lateral pressure to the base from both sides, and pressing the base completely into the top cover to complete the snap-fit ​​assembly. This ensures that the base and the top cover are snap-fitted in place and avoids problems such as misalignment during pressing or loose snap-fit. After pressing is completed, the first and second sliders move in opposite directions, and the two pressure rods move away from each other and reset, waiting for the next pressing operation.

The first workpiece gripper 15131 is used to take out the assembled inverted rotary switch from the assembly loading device 123 of the indexing unit 12 and place it on the rotary switch flipping mechanism 152 to complete the flipping. The second workpiece gripper 15132 grabs the flipped upright rotary switch and moves it to the rotary switch carrier 162 on the unloading conveyor track 161. The second workpiece gripper 15132 can also be driven by the horizontal rotation module 1514 to rotate circumferentially around the vertical axis, thereby adjusting the angle of the upright rotary switch to align with the corresponding slot of the rotary switch carrier 162.

[0028] In use, the first workpiece gripper moves down to pick up the assembled inverted rotary switch from the loading fixture on the indexing plate. Then, the vertical lifting module drives the double gripper assembly to rise, and the horizontal translation module moves the inverted rotary switch to the gripping position of the flipping gripper. After the first workpiece gripper places the workpiece in place, the flipping gripper holds the workpiece. The flipping rotation module drives the flipping gripper to complete a 180° rotation, turning the inverted rotary switch to the upright position. Then, the horizontal translation module continues to drive the double gripper assembly to move, and the second workpiece gripper moves down to grab the upright rotary switch that has been flipped. If there is a deviation in the workpiece angle, the horizontal rotation module drives the second workpiece gripper and the upright rotary switch to rotate around the vertical axis to adjust the workpiece angle so that it is aligned with the corresponding slot of the rotary switch carrier. Then, the second workpiece gripper moves down to put the upright rotary switch into the rotary switch carrier to complete the loading.

The switch positioning mechanism 171 includes a pair of positioning plates 1711 and a positioning plate driving module 1712.

[0030] The aforementioned horizontal rotation module, flipping rotation module, and first rotation drive component can be driven by a stepper motor-driven gear pair or a synchronous belt pulley pair to meet the accuracy requirements for rotation and attitude adjustment.

[0031] In use, the feeding conveyor rail transports the rotary switch carrier and the upright rotary switch to the 0 position. The positioning plate drive module of the switch positioning mechanism drives a pair of positioning plates to move closer together, clamping the upper cover outer wall of the limit rotary switch from both sides to complete the positioning and fixing of the rotary switch. Then, the first lifting drive component drives the first rotating drive component and the rotating clamping component to move downward.

It also includes a host computer control system, which is electrically connected to the turntable unit, the carrier detection unit, the knob rotation unit, and the knob toggle unit, respectively, to control the actions of each unit and to receive and process detection data.

[0033] Specifically, the carrier detection unit 23 includes a carrier base 231.

The horizontal sliding drive module 262 is used to drive the knob hook pull member 261 to move the knob cap horizontally, so as to realize the tossing of the knob cap. During the tossing process, the magnitude of the force can also be monitored in real time by a force sensor. When an abnormal resistance is detected (such as excessive or insufficient resistance), a signal is immediately fed back to the host computer control system.

Then, the turntable unit drives the carrier detection unit to rotate sequentially through the knob rotation unit and the knob toggle unit for detection. The second lifting drive unit of the knob rotation unit drives the knob gripper to descend and clamp the knob cap. Then the second rotation drive unit drives the knob cap to rotate at a preset angle to switch to a preset gear. After each gear switch, the resistance tester automatically collects the resistance data of the current gear and uploads it to the host computer control system to determine whether the resistance of the gear meets the requirements. After the gear rotation test is completed, the second vertical sliding drive module of the knob actuation unit drives the knob hook to descend. The hook fits onto the knob cap, and then the horizontal sliding drive module drives the hook to reciprocate the knob cap horizontally. The force sensor monitors the magnitude of the force during the actuation process in real time, and the resistance tester simultaneously collects resistance data at different actuation positions and uploads it to the host computer system for data comparison and judgment. After all items are tested, the turntable unit drives the carrier detection unit to rotate back to the loading and unloading unit station. The loading and unloading unit removes the tested knob switches and, according to the pass / fail results determined by the host computer, transfers them to the corresponding pass / fail unloading area and fail / fail unloading area, respectively, completing the entire testing process.
