[0003] However, traditional methods for assembling semi-finished switch components typically involve manually assembling the body, oscillating plate, toggle, and spring in sequence, which suffers from low assembly efficiency, unstable product quality, and low product qualification rate. Utility Model Content

[0004] Therefore, it is necessary to address the problems of low assembly efficiency, unstable product quality, and low product qualification rate associated with traditional switch semi-finished component assembly methods, which typically involve manually assembling the body, oscillating plate, toggle, and spring sequentially. A more efficient, automated switch semi-finished component assembly machine is needed, which offers high automation, stable product quality, and effectively improves assembly efficiency and product qualification rate.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: An automatic assembly machine for semi-finished switches, comprising: a chassis and a PLC control device, wherein the chassis is equipped with an intermittent rotating turntable mechanism, and assembly fixtures are evenly arranged on the circumferential edge of the turntable of the intermittent rotating turntable mechanism, which are sequentially arranged on the chassis along the rotation direction of the intermittent rotating turntable mechanism.

The body transfer component includes a horizontal feeding assembly, a body clamping assembly, and a horizontal pushing and lifting assembly. The horizontal feeding assembly is located at the discharge end of the body vibrating feeding component and pushes the body to the body clamping assembly. The horizontal pushing and lifting assembly drives the body clamping assembly to clamp the body and then drives the body clamping assembly to convey the body to the assembly fixture.

[0010] An automatic spring assembly mechanism is used to assemble a spring with a lever after adjusting its position. It includes a spring vibration feeding component, a spring pushing component located at the discharge end of the spring vibration feeding component and pushing the spring to the side of the picking position and then lifting the spring to the picking position, a spring rotation pushing component for rotating the spring by an assembly angle and driving it below the assembly robot, and a spring displacement component for clamping and conveying the spring from the picking position to the spring rotation pushing component.

The oscillating plate is pushed to the oscillating plate rotating component, which rotates the oscillating plate to the assembly setting angle. Then, the flat pushing component pushes the oscillating plate on the oscillating plate rotating component forward and conveys it to the positioning block. The oscillating plate assembly component then picks up the oscillating plate from the positioning block and assembles it onto the main body. The carrier pushing component closes the assembly fixture, fixing the oscillating plate onto the main body. The intermittent rotating turntable mechanism then transfers the assembly to the oiling mechanism. The slide cylinder drives the nozzle to approach the positioning column, causing the nozzle to spray lubricating oil onto the positioning column. After oiling, the intermittent rotating turntable mechanism transfers the assembly to below the assembly robot. The actuator vibration feeding component conveys the actuators one by one, and the actuator pushing component rotates the actuators. The mechanism pushes the actuator to the discharge end of the vibrating feed component, and the pushing component pushes the actuator into the actuator rotating mechanism. The rotating mechanism rotates the actuator to a set angle, and the actuator forward pushing component pushes the rotated actuator to a position below the assembly robot. The upward pushing component then pushes the actuator out of the rotating actuator. Simultaneously, the spring vibrating feed component feeds springs one by one, and the spring pushing component delivers the springs to the picking position. The spring displacement component then grabs the springs at the picking position and delivers them to the spring rotating forward pushing component. The spring rotating forward pushing component rotates the springs to the set angle and drives them to the assembly robot. The assembly robot assembles the actuator and springs, and then the assembly robot... The assembly parts are manually assembled onto the positioning pins of the assembly fixture body. After the semi-finished assembly is completed, it is transported to the moving drive component by the intermittent rotary turntable mechanism. The moving drive component opens the assembly fixture to allow the toggle to rotate. To prevent the swing plate and the body from moving, after the assembly fixture is opened, the forward control component is activated to fix the swing plate and the body. Then, the moving drive component drives the toggle to rotate at a set angle. After the toggle is adjusted, it is transported to the vision inspection mechanism by the intermittent rotary turntable mechanism. Two CCD camera components take pictures of the semi-finished assembly parts on the assembly fixture. The CCD camera components feed the signals back to the PLC control device. The PLC control device analyzes and judges the signals and feeds the judgment information back to the unloading mechanism.After inspection, the semi-finished components are conveyed to the unloading mechanism by an intermittent rotary turntable mechanism. Upon receiving a command from the PLC control device, the fixture opening component of the unloading mechanism is activated, opening the assembly fixture. Then, the finished product transfer component picks up the semi-finished assembly from the assembly fixture and conveys it to the dual-channel unloading track. Initially, the dual-channel unloading track is for good products; when a defective product is detected, the push component switches the dual-channel unloading track to the defective product unloading track, completing the entire assembly of the semi-finished components. This invention employs an intermittent rotary turntable mechanism, combined with modular designs including a main body feeding mechanism, an automatic oscillating plate assembly mechanism, an oiling mechanism, an automatic toggle assembly mechanism, an automatic spring assembly mechanism, an assembly angle adjustment mechanism, a visual inspection mechanism, and an unloading mechanism, achieving automated assembly of switch semi-finished products.

[0042] Please see Figure 3 and Figure 4This embodiment provides an automatic assembly machine for semi-finished switch products. The automatic assembly machine for semi-finished switch products includes a chassis 10 and a PLC control device. The chassis 10 is equipped with an intermittent rotating turntable mechanism 20. Assembly fixtures 30 are evenly arranged on the circumferential edge of the turntable of the intermittent rotating turntable mechanism 20. Along the rotation direction of the intermittent rotating turntable mechanism 20, the following are sequentially arranged on the chassis 10: a body feeding mechanism 40, an automatic assembly mechanism for swing plates 50, an oiling mechanism 60, an automatic assembly mechanism for toggle levers 70, an automatic assembly mechanism for springs 80, an assembly angle adjustment mechanism 90, a visual inspection mechanism 100, and a unloading mechanism 110.

[0043] The main body is conveyed to the main body transfer component 42 by the main body vibration feeding component 41. The main body clamping component 421 is driven by the flat push lifting component 422 to clamp the main body and deliver the main body to the assembly fixture 30. The intermittent rotating turntable mechanism 20 transfers the main body to the area below the swing plate assembly component 55. The swing plate vibration feeding component 51 vibrates the swing plates 45 degrees and sends them one by one to the swing plate forward pushing component 52 through the straight vibrator. The swing plate forward pushing component 52 pushes the swing plates to the swing plate rotating component 53. The swing plate rotating component 53 rotates the swing plates to the assembly setting angle. Then, the flat push component 54 pushes the swing plates on the swing plate rotating component 53 forward and delivers them to the positioning block 32. Finally, the swing plate assembly component 55... The oscillating piece on the positioning block 32 is assembled onto the main body, and the carrier pusher 56 closes the assembly fixture 30, fixing the oscillating piece onto the main body. The intermittent rotary turntable mechanism 20 then transfers the assembly to the oiling mechanism 60. The slide cylinder 61 drives the nozzle 62 to approach the positioning post, spraying lubricating oil onto the post. After oiling, the intermittent rotary turntable mechanism 20 transfers the assembly to below the assembly robot 77. The agitator vibration feeding component 71 feeds the agitators one by one, and the agitator forward pusher 75 pushes the agitator rotation mechanism 72 to the discharge end of the agitator vibration feeding component 71. The pusher 73 then pushes the agitators into the agitator rotation mechanism 72, causing the agitator rotation mechanism to rotate. When the lever 72 rotates, it is assembled at a set angle. The lever pushing component 75 pushes the lever rotating mechanism 72, which has been rotated to the set angle, to the bottom of the assembly robot 77. The lifting component 76 pushes the lever out of the lever rotating mechanism 72. At the same time, the spring vibration feeding component 81 feeds the springs one by one. The spring pushing component 82 feeds the springs from the spring vibration feeding component 81 to the picking position. Then, the spring displacement component 84 grabs the springs at the picking position and sends them to the spring rotation pushing component 83. The spring rotation pushing component 83 rotates the springs to the set angle and drives them to the assembly robot 77. The assembly robot 77 assembles the lever and the springs, and then assembles the assembly parts onto the positioning pins of the assembly fixture 30 body. After the semi-finished assembly is completed, it is transported to the moving drive component 91 by the intermittent rotary turntable mechanism 20. The moving drive component 91 opens the assembly fixture 30 so that the toggle can rotate. In order to prevent the swing plate and the body from moving, after the assembly fixture 30 is opened, the forward control component 92 is activated to fix the swing plate and the body. Then the moving drive component 91 drives the toggle to rotate at a set angle. After the toggle is adjusted, it is transported to the visual inspection mechanism 100 by the intermittent rotary turntable mechanism 20. Two CCD camera components take pictures of the semi-finished assembly on the assembly fixture 30. The CCD camera components feed the signal back to the PLC control device. The PLC control device analyzes and judges the signal and feeds the judgment information back to the unloading mechanism 110.After inspection, the semi-finished assembly is conveyed to the unloading mechanism 110 by the intermittent rotating turntable mechanism 20. Upon receiving a command from the PLC control device, the fixture opening component 111 of the unloading mechanism 110 is activated, opening the assembly fixture 30. Then, the finished product transfer component 112 picks up the semi-finished assembly from the assembly fixture 30 and conveys it to the dual-channel unloading track 113. Initially, the dual-channel unloading track 113 is a good product unloading track. When a defective product is detected, the push component 114 switches the dual-channel unloading track 113 to a defective product unloading track, completing the entire assembly of the semi-finished assembly.

[0044] In this embodiment, the main body vibration feeding component 41, the swing plate vibration feeding component 51, the toggle vibrating feeding component 71, and the spring vibration feeding component 81 all adopt a vibratory feeder and a straight vibrator. The straight vibrator is connected to the discharge end of the vibratory feeder. The straight vibrator conveys the main body, swing plate, toggle, and spring one by one. The use of a vibratory feeder and a straight vibrator for feeding prevents the parts from overlapping during the conveying process, ensuring that each part can be accurately delivered to the assembly position and guaranteeing the assembly yield.

[0045] Furthermore, to prevent assembly at each assembly station and to avoid movement or misalignment of components within the assembly fixture 30, please refer to [the relevant documentation]. Figure 5 In this embodiment, the main structure of the assembly fixture 30 includes a fixture body 31 fixed on the circumferential edge of the turntable. The fixture body 31 has a positioning block 32 in the middle. The fixture body 31 has sliding grooves on both sides. Baffles 33 are slidably arranged in the two sliding grooves, and limiting blocks that block the baffles 33 are provided at both ends of the sliding grooves. The two baffles 33 at the end away from the positioning block 32 have slots 34, and rollers 35 are provided in the slots 34. One end of one baffle 33 has a protrusion 36 for pressing the swing plate. The protrusion 36 has an inclined surface that contacts the spring. The baffle 33 is pressed or released by the drive component of the work station area to push the baffle 33 forward or insert it into the slot 34.

[0046] The following describes the specific structure and working principle of the main body feeding mechanism 40, the swing plate automatic assembly mechanism 50, the oiling mechanism 60, the toggle automatic assembly mechanism 70, the spring automatic assembly mechanism 80, the assembly angle adjustment mechanism 90, and the unloading mechanism 110.

The horizontal pushing and lifting component 422 drives the main body clamping component 421 to clamp the main body and sends the main body to the assembly fixture 30. The main body clamping component 421 adopts a pneumatic gripper.

[0048] The flat conveying assembly 420 includes a main body guide block 4201. The main body guide block 4201 has a discharge trough that communicates with the discharge end of the main body vibrating feeding component 41 and a main body forward push guide trough that communicates with the discharge trough. The flat conveying assembly 420 also includes a first push cylinder 4202 and a push rod 4203 located at the output end of the first push cylinder 4202 and pushed by the first push cylinder 4202 to slide along the main body forward push guide trough to push the main body to the lower part of the main body clamping assembly 421. An optical fiber sensor for sensing the main body is provided on the upper side of the discharge trough. The optical fiber sensor is fixed on the main body guide block 4201 by a mounting plate. When the optical fiber sensor senses the main body on the vibrator, the first push cylinder 4202 drives the push rod 4203 to push the main body to the lower part of the flat push lifting assembly 422. Then, the flat push lifting assembly 422 drives the main body clamping assembly 421 to grab and transport the main body to the assembly fixture 30.

[0049] Furthermore, the horizontal lifting assembly 422 includes a first bracket 4220 with a horizontal guide rail, a first movable seat 4221 with a vertical guide rail slidably mounted on the first bracket 4220, and a second push cylinder 4222 on the first bracket 4220 to drive the first movable seat 4221 to reciprocate along the horizontal guide rail; a first sliding plate 4223 is slidably mounted on the first movable seat 4221, a body clamping assembly 421 is mounted on the first sliding plate 4223, and a third push cylinder 4221 on the first movable seat 4221 to drive the first sliding plate 4223 to move up and down along the vertical guide rail. 24. The first moving seat 4221 is driven by the second pushing cylinder 4222 to move the body clamping assembly 421 onto the body. Then, the body clamping assembly 421 is driven by the third pushing cylinder 4224 to move down and grab the body. After grabbing, it is reset. Then, the first moving seat 4221 is driven by the second pushing cylinder 4222 to move the body clamping assembly 421 above the assembly fixture 30. Then, the body clamping assembly 421 is driven by the third pushing cylinder 4224 to move down, so that the body clamping assembly places the body on the assembly fixture 30, thus completing the automatic feeding of the body.

[0050] Please see Figure 7The automatic assembly mechanism 50 for assembling oscillating pieces is used to assemble oscillating pieces onto the main body. This automatic assembly mechanism 50 includes an oscillating piece vibrating feeding component 51, an oscillating piece forward pushing component 52, an oscillating piece rotating component 53, a horizontal pushing component 54, an oscillating piece assembly component 55, and a carrier pushing component 56. The vibrating plate of the oscillating piece vibrating feeding component 51 arranges the oscillating pieces at a 45-degree angle, and then the linear vibrator conveys the 45-degree oscillating pieces one by one to the oscillating piece forward pushing component 52. The oscillating piece forward pushing component 52 then pushes the oscillating pieces to the oscillating piece rotating component 53, and the oscillating piece rotating component... Part 53 rotates and corrects the set assembly angle of the swing plate, and then the flat pusher 54 pushes the swing plate with the rotated angle to the positioning block. The swing plate assembly part 55 grabs the swing plate and assembles it onto the main body of the assembly fixture 30. The carrier pusher 56 is located on the side of the assembly fixture 30. The carrier pusher 56 is equipped with a lifting cylinder. The output end of the lifting cylinder is equipped with a push plate. When the lifting cylinder drives the push plate to rise, it contacts the roller 35 of the baffle 33, thereby pushing the baffle 33 forward to press the swing plate. The swing plate assembly part 55 has the same structure as the main body transfer part 42.

[0051] The oscillating plate forward pushing component 52 includes a fourth pushing cylinder 520 and a movable swing member 521 located at the output end of the fourth pushing cylinder 520.

The automatic assembly mechanism 70 for toggle units includes a vibrating feeding component 71 for toggle units, a rotating mechanism 72 for toggle units, a pushing component 73, a pushing component 74 for toggle units, a forward pushing component 75 for toggle units, an upper lifting component 76, and an assembly robot 77. The vibrating plate and the linear vibrator of the vibrating feeding component 71 for toggle units convey the toggle units one by one. The forward pushing component 75 pushes the rotating mechanism 72 for toggle units to the discharge end of the vibrating feeding component 71 for toggle units. The pushing component 73 pushes the toggle unit into the rotating mechanism 72 for toggle units, so that the rotating mechanism 72 assembles the toggle unit at a set angle when rotating it. The forward pushing component 75 pushes the rotated rotating mechanism 72 for toggle units at the set angle to the bottom of the assembly robot 77. The upper lifting component 76 pushes the toggle unit out of the rotating mechanism 72 for toggle units.

[0054] The toggle rotating mechanism 72 includes a base 720 with a horizontal slide rail and a movable mounting seat 721 slidably mounted on the base 720. A toggle pushing component 75 is located on the base 720 and drives the movable mounting seat 721 to reciprocate along the horizontal slide rail. A toggle pushing component 74 and an upward pushing component 76 are located on the movable mounting seat 721. One end of the movable mounting seat 721 is provided with a drive pulley and a drive motor that drives the drive pulley to rotate. The other end of the movable mounting seat 721 is equipped with a hollow rotating shaft rotatably connected to the mounting seat via a bearing. The hollow rotating shaft is provided with a driven pulley 722 that is connected to the drive pulley via a belt. The driven pulley 722 is provided with a receiving block 723, which has a second receiving groove and a bottom hole communicating with the second receiving groove. The bottom hole is coaxial with the hollow rotating shaft. The upper lifting component 76 includes a top rod slidably disposed in the hollow rotating shaft and a lifting cylinder 760 that drives the top rod through the bottom hole to the second receiving groove to lift the toggle. The cylinder of the toggle pushing component 75 pulls the movable mounting base 721 to move the receiving block 723 to the discharge end of the vibrator. After the fiber optic sensor on the receiving block 723 senses the toggle, the pushing component 73 pushes the toggle into the second receiving groove. The toggle pushing component 75 pushes the receiving block 723 away from the vibrator. At this time, the drive motor starts, causing the driven pulley 722 to rotate and rotate the toggle to the assembly set angle. At the same time, the toggle pushing component 75 moves the movable mounting base 721 to move the receiving block 723 to below the assembly robot 77. The lifting cylinder 760 drives the top rod to lift the toggle in the second receiving groove, waiting for the assembly robot 77 to grab it.

[0055] Please see Figure 10The automatic spring assembly mechanism 80 is used to assemble the spring with the actuator after adjusting its position. The automatic spring assembly mechanism 80 includes a spring vibration feeding component 81, a spring pushing component 82, a spring rotation forward pushing component 83, and a spring displacement component 84. The spring vibration feeding component 81 feeds the springs one by one through its vibratory plate and linear vibrator. The spring pushing component 82 feeds the springs from the spring vibration feeding component 81 to the picking position. Then, the spring displacement component 84 picks up the springs from the picking position and sends them to the spring rotation forward pushing component 83. The spring rotation forward pushing component 83 rotates the springs to the assembly angle and drives them to the assembly robot 77. The assembly robot 77 assembles the actuator with the spring and then assembles the assembly components onto the positioning post of the assembly fixture 30 body.

[0056] The spring pushing component 82 includes two vertically arranged pushing cylinders. First, the pushing cylinder located at the discharge end of the vibrator pushes the spring to the picking position, and then the other pushing cylinder starts to lift it to the position. The spring displacement component 84 includes a front pushing component and a pneumatic gripper on the front pushing component. The front pushing component drives the pneumatic gripper to move to the picking position, and the pneumatic gripper grabs the spring and transports it to the spring rotation front pushing component 83.

[0057] In addition, the spring rotation push component 83 includes an L-shaped frame 830 with a horizontal slide rail, a moving platform 831 sliding on the L-shaped frame 830, and a seventh push cylinder 832 with its output end connected to the moving platform 831. One end of the moving platform 831 is provided with a second rotating cylinder 833, and the second rotating cylinder 833 is provided with a clamping cylinder 834. The clamping cylinder 834 clamps the spring delivered by the spring displacement component 84, and the second rotating cylinder 833 drives the spring to rotate to the assembly set angle. The seventh push cylinder 832 then delivers the rotated spring to the bottom of the assembly robot 77, so that the assembly robot 77 assembles the toggle and the spring, and then the assembly robot 77 assembles the assembled toggle and spring assembly onto the main body.

[0058] After the toggle and spring assembly are assembled onto the main body, the toggle needs to be rotated to the required angle for the switch. For this purpose, an assembly angle adjustment mechanism 90 is provided. The angle of the toggle is adjusted using the assembly angle adjustment mechanism 90. Please refer to [link / reference]. Figure 11 The assembly angle adjustment mechanism 90 includes a movement drive component 91 and a forward movement control component 92;

[0059] The moving drive component 91 includes a vertical slide cylinder 910 and a slide frame 911 mounted on the vertical slide cylinder 910. The slide frame 911 has a rod 912 on its side that contacts the roller 35 and inserts into the slot 34 to push the baffle 33. The slide frame 911 is equipped with a rotary motor 913, and the output shaft of the rotary motor 913 has a rotating block that contacts the toggle. The forward movement control component 92 includes a horizontal slide cylinder 920 and a rod 912 mounted on the horizontal slide cylinder 910. The pressure plate 921 on the 20 is driven by the vertical slide cylinder 910 to move the slide frame 911 downward, so that the roller 35 of the insertion rod 912 contacts and inserts into the slot 34 to push the baffle 33, so that the baffle 33 is disengaged from the spring. At the same time, the horizontal slide cylinder 920 drives the pressure plate 921 to approach the swing plate, so as to prevent the swing plate from tilting when the rotary motor 913 drives the rotary insertion block to rotate the toggle. After the pressure plate 921 reaches the position, the rotary motor 913 drives the rotary insertion block to rotate the toggle.

[0060] Please see Figure 12 The unloading mechanism 110 is used to deliver the assembled finished products out of the equipment. The unloading mechanism 110 is used to open the fixture opening part 111 of the assembly fixture 30, the finished product transfer part 112 for taking out the assembled finished products in the assembly fixture 30, the dual-channel unloading track 113 for conveying good products and defective products, and the pushing part 114 for driving the dual-channel unloading track 113 to switch the unloading track. The finished product transfer part 112 has the same structure as the main body transfer part 42. The pushing part 114 includes a support frame and a telescopic cylinder provided on the support frame. The dual-channel unloading track 113 is provided at the output end of the telescopic cylinder, and the telescopic cylinder switches the good product unloading track and the defective product unloading track.

[0061] In addition, the fixture opening component 111 includes a mounting base 1110 and a lifting cylinder 1111 disposed on the mounting base 1110. The output end of the lifting cylinder 1111 is provided with a horizontal plate 1112. The horizontal plate 1112 is provided with push rods 1113 on both sides corresponding to the baffles 33 on both sides of the assembly fixture 30. The lifting cylinder 1111 drives the horizontal plate 1112 to move the two push rods 1113 downward, so that the push rods 1113 push the roller 35 to rotate and insert into the slot 34, thereby pushing the baffle 33 to disengage from the body, thereby realizing the opening of the assembly fixture 30. Then, the finished product transfer component 112 takes out the finished product from the assembly fixture 30.

[0062] In summary, this utility model has the advantages of high automation, low labor costs, and stable product quality, which can effectively improve assembly efficiency and product qualification rate, meet the needs of large-scale standardized production, realize the full automation of product assembly process from automatic material feeding and distribution to automatic assembly, improve product production efficiency and qualification rate, and enhance company benefits and competitiveness.
