[0075] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0076] like Figures 1-26 As shown, this embodiment of the invention provides a limit switch core assembly device for assembling limit switch cores 100. The limit switch core 100 includes a button assembly, a base 1001, and a spring 1002. The button assembly includes a push rod 1003, a connecting rod 1004, a toggle block 1005, and two spring pieces 1006.

[0077] The limit switch core assembly equipment includes a frame and a rotating mechanism 1, a button assembly mechanism 2, a first transfer mechanism 3, a spring assembly mechanism 4, a base assembly mechanism 5, a second transfer mechanism 6, and a detection output mechanism 7, all mounted on the frame.

[0078] The rotating mechanism 1 includes a conveying module 11 and a carrier 12. The conveying module 11 can be configured as a ring, and the carrier 12 is disposed on the conveying module 11. The conveying module 11 can drive the carrier 12 to rotate. The carrier 12 is provided with a first mounting position 121, a second mounting position 122 and a third mounting position 123.

[0079] The button assembly mechanism 2 is located on the periphery of the conveying module 11. The conveying module 11 drives the carrier 12 to move to the position corresponding to the button assembly mechanism 2. The button assembly mechanism 2 can place the push rod 1003, the connecting rod 1004 and the two spring pieces 1006 in the first mounting position 121 in sequence and assemble them to form a button assembly.

[0080] The first transfer mechanism 3 is disposed on the periphery of the conveying module 11 and located downstream of the button assembly assembly mechanism 2. The conveying module 11 drives the carrier 12 to move to the position corresponding to the first transfer mechanism 3. The first transfer mechanism 3 can transfer the button assembly assembled at the first mounting position 121 to the second mounting position 122.

[0081] The spring assembly mechanism 4 is located on the periphery of the conveying module 11 and downstream of the first transfer mechanism 3. The conveying module 11 drives the carrier 12 to move to the position corresponding to the spring assembly mechanism 4. The spring assembly mechanism 4 can transfer the spring 1002 to the second mounting position 122 and assemble it with the button assembly transferred to the second mounting position 122.

[0082] The base assembly mechanism 5 is located on the periphery of the conveying module 11 and downstream of the spring assembly mechanism 4. The conveying module 11 drives the carrier 12 to move to the position corresponding to the base assembly mechanism 5. The base assembly mechanism 5 can transfer the base 1001 to the second mounting position 122 and simultaneously assemble it with the button assembly and the spring 1002 to form the limit switch core 100.

[0083] The second transfer mechanism 6 is located on the periphery of the conveying module 11 and downstream of the base assembly mechanism 5. The conveying module 11 drives the carrier 12 to move to the position corresponding to the second transfer mechanism 6. The second transfer mechanism 6 can transfer the limit switch core 100 located at the second mounting position 122 to the third mounting position 123.

[0084] The detection output mechanism 7 is located on the periphery of the conveying module 11 and downstream of the second transfer mechanism 6. The conveying module 11 drives the carrier 12 to move to the position corresponding to the detection output mechanism 7. The detection output mechanism 7 can detect whether the limit switch core 100 placed in the third mounting position 123 is qualified, and place the qualified limit switch core 100 in the good product flow channel 734 for output, and place the unqualified limit switch core 100 in the waste product flow channel 735 for output.

[0085] This limit switch core assembly equipment enables 100% automatic assembly of limit switch cores, completely replacing manual assembly, improving production efficiency and ensuring product consistency.

[0086] In this embodiment, multiple carriers 12 can be provided, and multiple carriers 12 are spaced apart on the conveying module 11, which can effectively improve production efficiency.

[0087] Specifically, the carrier 12 is provided with a slot 1213 and a recess 1214 at the first mounting position 121 (see reference). Figure 4 For ease of demonstration of slot 1213 and recess 1214, Figure 4The first pressure plate 1211 and the second pressure plate 1212 at the first mounting position 121 are hidden. The button assembly mechanism 2 includes a push rod feeding mechanism 21, a connecting rod feeding mechanism 22 and a spring assembly mechanism 23 arranged sequentially around the conveying module 11. The conveying module 11 drives the carrier 12 to move to the position corresponding to the push rod feeding mechanism 21. The push rod feeding mechanism 21 can transfer the push rod 1003 into the slot 1213 of the first mounting position 121 on the carrier 12. The conveying module 11 drives the carrier 12 to move to the position corresponding to the connecting rod feeding mechanism 22. The connecting rod feeding mechanism 22 can transfer the connecting rod 1004 into the recessed groove 1214 of the first mounting position 121 on the carrier 12.

[0088] The spring assembly mechanism 23 includes an angle-adjustable pick-and-place module 231, which includes a pick-and-place module 2311. The pick-and-place module 2311 includes a rotating component and a pick-and-place component 2311d. The pick-and-place component 2311d can grab and release the spring 1006. The pick-and-place component 2311d is mounted on the rotating component. The conveying module 11 drives the carrier 12 to move to a position corresponding to the angle-adjustable pick-and-place module 231. The rotating component can drive the pick-and-place component 2311d to rotate so that the pick-and-place component 2311d is in an inclined state to release the spring 1006, that is, to place the spring 1006 on the carrier 12 at a set inclination angle so that the spring 1006 is connected to the push rod 1003 and the connecting rod 1004.

[0089] The rotating component drives the picking and placing component 2311d to rotate, so that after picking up the spring 1006, the picking and placing component 2311d can release the spring 1006 at a set tilt angle to realize the assembly of the button component, avoiding manual intervention and improving production efficiency and product consistency.

[0090] In this embodiment, the angle-adjustable pick-and-place module 231 includes two symmetrically distributed pick-and-place modules 2311. The rotating assembly includes a mounting horizontal plate 2311a, a rotating plate 2311b, and a rotating drive assembly 2311c. The two mounting horizontal plates 2311a are spaced apart, and the two rotating plates 2311b are rotatably mounted on the two mounting horizontal plates 2311a via rotating shafts. The two pick-and-place assemblies 2311d are respectively mounted on the two rotating plates 2311b. The rotating drive assembly 2311c is used to drive the corresponding rotating plate 2311b to rotate, so that the two rotating plates 2311b respectively drive the two pick-and-place assemblies 2311d to rotate, so that the pick-and-place assemblies 2311d can switch between vertical and inclined rotation states. When the two pick-and-place components 2311d are respectively gripping the spring piece 1006, the two rotary drive components 2311c drive the rotary plate 2311b to rotate so that the pick-and-place components 2311d are in a vertical state to grip the spring piece 1006. When the two pick-and-place components 2311d are assembling the spring piece 1006 at the first mounting position 121, the two rotary drive components 2311c drive the rotary plate 2311b to rotate so that the pick-and-place components 2311d are in an inclined state to release the spring piece 1006, that is, to install the two spring pieces 1006 on the push rod 1003 and the connecting rod 1004 at a set tilt angle. In this embodiment, the connecting rod 1004 is provided with a through groove 1004a. Along the length direction of the connecting rod 1001, both ends of the through groove 1004a are provided with a first locking groove 1004b. The push rod 1003 is provided with a second locking groove 1003a. When the connecting rod 1004 is placed in the recessed groove 1214 and the push rod 1003 is installed in the slot 1213, the push rod 1003 passes through the through groove 1004a, and both ends of the spring piece 1006 are respectively locked in the first locking groove 1004b and the second locking groove 1003a.

[0091] Two rotary drive components 2311c drive two rotary plates 2311b to rotate, which in turn drive two pick-and-place components 2311d to rotate. This allows the pick-and-place components 2311d to grab the spring 1006 in a vertical position and release it at a set tilt angle, thus achieving material picking and placing. This avoids manual intervention and improves production efficiency and product consistency.

[0092] Optionally, the spring assembly mechanism 23 further includes a spring conveying platform 233 and a spring vibrator 234. The spring conveying platform 233 is provided with two spring tracks, the feed end of the spring tracks is connected to the discharge end of the spring vibrator 234, and the spring conveying platform 233 is provided with a spring distribution block at the discharge end of the spring tracks. The spring distribution block is provided with two spring distribution slots corresponding to the two spring tracks. The spring vibrator 234 is used to accommodate the spring 1006 and can convey the spring through the spring tracks when it vibrates. The spring distribution cylinder can drive the spring distribution block to be misaligned with the spring conveying platform 233 after the spring 1006 enters the spring distribution slot, so as to facilitate the material picking and unloading assembly 2311d to pick up the material.

[0093] Since the spacing between the two spring rails and the spacing between the two springs 1006 during installation are different, the angle-adjustable pick-and-place module 231 also includes a first pitch-changing drive 2312 (which can be a gripper cylinder). Two mounting horizontal plates 2311a are set at the drive end of the first pitch-changing drive 2312. The first pitch-changing drive 2312 can drive the two mounting horizontal plates 2311a to move closer or further apart. When the two pick-and-place components 2311d pick up materials, the first pitch-changing drive 2312 can drive the two pick-and-place components 2311d to move further apart, so that the spacing between the two pick-and-place components 2311d is equal to the spacing between the two spring rails. When the two pick-and-place components 2311d release materials, the first pitch-changing drive 2312 can drive the two pick-and-place components 2311d to move closer together, so that the spacing between the two pick-and-place components 2311d is equal to the spacing between the two springs 1006 during installation.

[0094] In this embodiment, the angle-adjustable pick-and-place module 231 further includes a first horizontal drive member 2313 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder or linear module) and a first lifting drive member 2314 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder or linear module). The first horizontal drive member 2313 is disposed on the frame, the first lifting drive member 2314 is disposed at the drive end of the first horizontal drive member 2313, and the first variable pitch drive member 2312 is disposed at the drive end of the first lifting drive member 2314. The first horizontal drive member 2313 can drive the pick-and-place assembly 2311d to reciprocate between the carrier 12 and the spring sheet conveying platform 233. The first lifting drive member 2314 can drive the pick-and-place assembly 2311d to rise and fall in the vertical direction, so as to realize the pick-and-place assembly 2311d picking up and placing materials.

[0095] Optionally, the rotary drive assembly 2311c includes a first rotary drive member 2311c1 (which may be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder) and a rotary linkage rod 2311c2. The two first rotary drive members 2311c1 are respectively disposed on two mounting horizontal plates 2311a. One end of the rotary linkage rod 2311c2 is hinged to the drive end of the first rotary drive member 2311c1, and the other end of the rotary linkage rod 2311c2 is hinged to the rotating plate 2311b. The first rotary drive member 2311c1 drives the rotary linkage rod 2311c2 to rotate, so that the rotary linkage rod 2311c2 pushes the rotating plate 2311b to rotate.

[0096] Optionally, a limiting slide 2311a1 is provided on the mounting plate 2311a. A limiting slider 2311c3, slidably mounted on the limiting slide 2311a1, is provided at the driving end of the first rotary drive member 2311c1. One end of the rotary linkage 2311c2 is hinged to the limiting slider 2311c3. The first rotary drive member 2311c1 can drive the limiting slider 2311c3 to reciprocate within the limiting slider 2311c3, thereby causing the limiting slider 2311c3 to move the rotary linkage 2311c2. By providing the mutually slidingly connected limiting slide 2311a1 and limiting slider 2311c3, the limiting slider 2311c3 becomes more stable when moving the rotary linkage 2311c2, and the rotation of the rotating plate 2311b becomes more precise.

[0097] To ensure that the material handling assembly 2311d accurately switches to a vertical state when handling materials and accurately switches to an inclined state when discharging materials, the material handling module 2311 also includes a first limiting member 2311e and a second limiting member 2311f, which are spaced apart on the mounting plate 2311a along the sliding direction of the limiting slider 2311c3. When the material handling assembly 2311d handles materials, the first rotary drive member 2311c1 drives the limiting slider 2311c3 to move and abut against the first limiting member 2311e. When the material handling assembly 2311d is discharging material, the first rotary drive 2311c1 drives the limiting slider 2311c3 to move and abut against the second limiting member 2311f. By adjusting the displacement of the first limiting member 2311e and the second limiting member 2311f along the sliding direction of the limiting slider 2311c3, the rotation angle of the rotating plate 2311b can be adjusted according to the actual material handling angle (which may have errors after actual assembly) and the material discharging angle (which may have errors after actual assembly) to make the material handling more accurate.

[0098] Specifically, along the sliding direction of the limiting slider 2311c3, the mounting plate 2311a is provided with a first boss 2311a2 and a second boss 2311a3 spaced apart. The first boss 2311a2 is provided with a first threaded hole, and the second boss 2311a3 is provided with a second threaded hole. The first limiting member 2311e (which can be a buffer or a screw) is screwed into the first threaded hole, and the second limiting member 2311f (which can be a buffer or a screw) is screwed into the second threaded hole. By rotating the first limiting member 2311e and the second limiting member 2311f, the positions of the first limiting member 2311e and the second limiting member 2311f can be adjusted.

[0099] Optionally, the material handling assembly 2311d includes a material handling drive 2311d1 (which can be a pneumatic cylinder, electric cylinder, or hydraulic cylinder), a material handling guide block 2311d2, and a suction component 2311d3. The material handling drive 2311d1 is mounted on the rotating plate 2311b, and the material handling guide block 2311d2 is slidably mounted on the rotating plate 2311b via a guide rail slider structure. The material handling guide block 2311d2 and the material handling drive 2311d3 are connected. The drive end of 311d1 is connected, and the pick-and-place guide block 2311d2 is provided with a guide slide. The suction component 2311d3 is slidably disposed in the guide slide. The suction component 2311d3 is provided with an air passage. The end of the suction component 2311d3 near the pick-and-place drive component 2311d1 is elastically connected to the pick-and-place guide block 2311d2. The end of the suction component 2311d3 away from the pick-and-place drive component 2311d1 is provided with a connection to the air passage. The suction nozzle 2311d4 is connected to a vacuum device, which can generate negative or positive pressure in the air passage. When the pick-up and unload drive unit 2311d1 drives the pick-up and unload guide block 2311d2 to move the suction unit 2311d3 toward the spring sheet conveying table 233, due to the elastic connection between the suction unit 2311d3 and the pick-up and unload guide block 2311d2, when the suction nozzle 2311d4 abuts against the spring sheet 1006, the suction unit 2311d4... 1d3 can move away from the spring 1006 to achieve elastic buffering, which can prevent the spring 1006 from being crushed. At the same time, negative pressure is generated in the air passage to enable the suction nozzle 2311d4 to suck up the material. When the material pick-up and drop drive 2311d1 drives the material pick-up and drop guide block 2311d2 to drive the suction component 2311d3 to move toward the carrier 12 and release the material, positive pressure is generated in the air passage so that the spring 1006 is connected to the push rod 1003 and the connecting rod 1004.

[0100] In this embodiment, an L-shaped pressure rod 2311d5 is provided at one end of the material pick-up and drop guide block 2311d2 near the material pick-up and drop drive member 2311d1. The vertical rod of the L-shaped pressure rod 2311d5 is connected to the material pick-up and drop guide block 2311d2. An elastic element (which can be a compression spring) is connected between the L-shaped pressure rod 2311d5 and the suction member 2311d3. When the suction nozzle 2311d4 on the suction member 2311d3 abuts against and picks up the spring sheet, the suction member 2311d3 can move and compress the elastic element to achieve elastic buffering.

[0101] The spring assembly mechanism 23 also includes a spring clamping module 232, which is disposed on the periphery of the conveying module 11 and located downstream of the angle-adjustable pick-and-place module 231. The spring clamping module 232 is used to clamp the spring 1006 installed on the first mounting position 121 so that the spring 1006 is installed in place.

[0102] Specifically, the spring clamping module 232 includes two spring clamping drive members 2321 (which can be selected as pneumatic cylinders, hydraulic cylinders or electric cylinders) and two clamping rods 2322. The spring clamping drive members 2321 are mounted on the frame, and the two clamping rods 2322 are respectively mounted on the drive ends of the two spring clamping drive members 2321. The two clamping rods 2322 are inclined, and their inclination angle is the same as the inclination angle of the material pick-and-place assembly 2311d when it is in an inclined state. The two spring clamping drive members 2321 drive the two clamping rods 2322 to move toward the two springs 1006, so that the two clamping rods 2322 press against the two springs 1006 respectively.

[0103] In this embodiment, the carrier 12 is provided with two first mounting positions 121, two second mounting positions 122 and two third mounting positions 123. The two first mounting positions 121 are arranged in a row, the two second mounting positions 122 and the two third mounting positions 123 are arranged in a row, and the two third mounting positions 123 are located between the two second mounting positions 122. This carrier 12 structure allows two limit switch cores 100 to be assembled on each carrier 12 at one time.

[0104] Optionally, the push rod feeding mechanism 21 includes a push rod vibrator 211, a push rod conveying platform 212, a feeding transfer component 213, and a push rod transfer component 214. The push rod conveying platform 212 is provided with two push rod tracks. The push rod vibrator 211 is used to accommodate the push rod 1003 and can generate vibration so that the push rod 1003 is conveyed through the push rod tracks. When the push rod 1003 is conveyed to the discharge end of the push rod track, the feeding transfer component 213 grabs the push rod 1003, and the push rod transfer component 214 then transfers the push rod 1003 grabbed by the feeding transfer component 213 to the first mounting position 121 on the carrier 12.

[0105] Specifically, the feeding transfer component 213 includes a second rotary drive component 2131 (which can be a cylinder, hydraulic cylinder or electric cylinder) and two transfer gripper cylinders 2132. The second rotary drive component 2131 is mounted on the frame and can drive the two transfer gripper cylinders 2132 to rotate so that the two transfer gripper cylinders 2132 grab the push rod 1003 at the discharge end of the push rod track, and then rotate 90° to face the push rod transfer component 214 so that the push rod transfer component 214 can grab the push rod 1003 on the transfer gripper cylinder 2132 and place it in the first mounting position 121 on the carrier 12.

[0106] Specifically, the push rod transfer component 214 includes a second horizontal drive component 2141 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder or linear module), a second lifting drive component 2142 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder or linear module) and two push rod gripper cylinders 2143. The second horizontal drive component 2141 is mounted on the frame, the second lifting drive component 2142 is mounted on the drive end of the second horizontal drive component 2141, and the two push rod gripper cylinders 2143 are mounted on the drive end of the second lifting drive component 2142. The second horizontal drive component 2141 can drive the two push rod gripper cylinders 2143 to reciprocate between the carrier 12 and the feeding transfer component 213. The second lifting drive component 2142 can drive the two push rod gripper cylinders 2143 to lift and lower, so that the two push rod gripper cylinders 2143 can grab the push rod 1003 on the two transfer gripper cylinders 2132 and place it on the carrier 12.

[0107] Optionally, the link feeding mechanism 22 includes a vibrating hopper 221, a flexible vibrating plate 222, a robot arm 223, and a vision system. The vibrating hopper 221 is used to accommodate the link 1004 and feed it to the flexible vibrating plate 222 through vibration. The vision system takes pictures and analyzes the flexible vibrating plate 222 and sends signals to the robot arm 223. The robot arm 223 grabs the link 1004 according to the signals sent by the vision system and transfers it to the first mounting position 121 of the carrier 12.

[0108] The first mounting position 121 of the carrier 12 is provided with a first pressure plate 1211 and a second pressure plate 1212. The first pressure plate 1211 and the second pressure plate 1212 are clamped together by elastic force. The frame is provided with a spreading mechanism 13. When the push rod 1003 or the connecting rod 1004 is feeding, the spreading mechanism 13 can spread the first pressure plate 1211 and the second pressure plate 1212 apart so that the first pressure plate 1211 and the second pressure plate 1212 are far apart. After the push rod 1003 or the connecting rod 1004 is placed, the spreading mechanism 13 releases the first pressure plate 1211 and the second pressure plate 1212. The first pressure plate 1211 and the second pressure plate 1212 clamp the push rod 1003 and the connecting rod 1004 by elastic force.

[0109] Specifically, the spreading mechanism 13 includes a first lifting cylinder 131 and a first gripper cylinder 132. The first lifting cylinder 131 is mounted on the frame and is used to drive the first gripper cylinder 132 to rise, so that the two grippers of the first gripper cylinder 132 engage with the first pressure plate 1211 and the second pressure plate 1212 respectively, so that the first gripper cylinder 132 drives the first pressure plate 1211 and the second pressure plate 1212 to separate. The first lifting cylinder 131 can also drive the first gripper cylinder 132 to fall, so that the first gripper cylinder 132 separates from the first pressure plate 1211 and the second pressure plate 1212, and the first pressure plate 1211 and the second pressure plate 1212 move closer to each other and clamp.

[0110] It is understood that there are two spring assembly mechanisms 23, namely, two angle-adjustable picking and placing modules 231 and two spring pressing modules 232. The two angle-adjustable picking and placing modules 231 respectively install two springs 1006 at the two first mounting positions 121, and the two spring pressing modules 232 respectively press the springs 1006 installed at the two first mounting positions 121.

[0111] The button assembly mechanism 2 also includes a toggle assembly mechanism 24, which is disposed on the periphery of the conveying module 11 and downstream of the spring pressing module 232. The toggle assembly mechanism 24 can install the toggle 1005 onto the push rod 1003 located at the first mounting position 121 to form a button assembly.

[0112] Specifically, the push block assembly mechanism 24 includes a push block vibrator 241, a push block conveying platform 242, and a push block transfer component 243. The push block conveying platform 242 is provided with two push block tracks. The feeding end of the push block track is connected to the discharge end of the push block vibrator 241. The push block conveying platform 242 is provided with a push block distribution block 2421 at the discharge end of the push block track. The push block distribution block 2421 is provided with two push block distribution slots. The push block vibrator 241 is used to accommodate the push block 1005 and can generate vibration so that the push block is conveyed through the push block track. When the push block enters the push block distribution slot, the push block distribution cylinder 2422 drives the push block distribution block 2421 to be misaligned with the push block conveying platform 242. The push block transfer component 243 transfers the push block in the push block distribution slot to the first mounting position 121 of the carrier 12 and installs it on the push rod 1003 to form a button assembly.

[0113] More specifically, the block transfer component 243 includes a third horizontal drive component 2431 (which can be a cylinder, hydraulic cylinder, electric cylinder, or linear module), a third lifting drive component 2432 (which can be a cylinder, hydraulic cylinder, electric cylinder, or linear module), and two block gripper cylinders 2433. The third horizontal drive component 2431 is mounted on the frame, the third lifting drive component 2432 is mounted on the drive end of the third horizontal drive component 2431, and the block gripper cylinders 2433 are mounted on the drive end of the third lifting drive component 2432. The third horizontal drive component 2431 can drive the block gripper cylinders 2433 to reciprocate between the block conveying platform 242 and the carrier 12. The third lifting drive component 2432 can drive the block gripper cylinders 2433 to rise and fall vertically, so that the block gripper cylinders 2433 can pick up the block at the discharge end of the block track and place the block 1005 on the carrier 12.

[0114] Specifically, the first transfer mechanism 3 includes a fourth horizontal drive component 31 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder, or linear module), a fourth lifting drive component 32 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder, or linear module), a second variable pitch drive component 33 (which can be selected as a gripper cylinder, gripper electric cylinder, or gripper hydraulic cylinder), two second lifting cylinders 34, and two second gripper cylinders 35. The fourth horizontal drive component 31 is mounted on the frame, the fourth lifting drive component 32 is mounted on the drive end of the fourth horizontal drive component 31, and the second variable pitch drive component 33 is mounted on the drive end of the fourth lifting drive component 32. Each drive end of the second variable pitch drive component 33 is provided with a moving plate 331. The two second lifting cylinders 34 are respectively mounted on the two moving plates 331, and the two second gripper cylinders 35 are respectively mounted on the two moving plates 331. The second gripper cylinder 35 on each moving plate 331 is connected to the drive end of the second lifting cylinder 34 through a first flipping component 36.

[0115] The fourth horizontal drive unit 31 drives the two second gripper cylinders 35 to move to the first mounting position 121 of the carrier 12. The second pitch drive unit 33 drives the two second gripper cylinders 35 to move so that the distance between the two second gripper cylinders 35 is the same as the distance between the two first mounting positions 121. The second lifting cylinder 34 drives the first tilting component 36 to move so that the second gripper cylinders 35 remain vertical. The fourth lifting drive unit 32 drives the second gripper cylinders 35 to descend so that the second gripper cylinders 35 grasp the button assembly on the first mounting position 121. Then, the fourth lifting drive unit... The actuator 32 drives the two second gripper cylinders 35 to rise, the second pitch drive 33 drives the two second gripper cylinders 35 to move so that the distance between the two second gripper cylinders 35 is the same as the distance between the two second mounting positions 122, the second lifting cylinder 34 drives the first flipping component 36 to move so that the second gripper cylinders 35 remain horizontal, the fourth horizontal drive 31 drives the two second gripper cylinders 35 to move to the second mounting position 122, and the fourth lifting drive 32 drives the two second gripper cylinders 35 to fall so that the button assembly is flipped and placed in the second mounting position 122.

[0116] Specifically, the first flipping component 36 includes a rack 361 and a gear shaft 362 that mesh with each other. The rack 361 is slidably disposed on the moving plate 331 and connected to the drive end of the second lifting cylinder 34. The gear shaft 362 is rotatably disposed on the moving plate 331 and connected to the corresponding second gripper cylinder 35. The second lifting cylinder 34 drives the rack 361 to slide up and down, thereby driving the gear shaft 362 to rotate, and thus driving the second gripper cylinder 35 to flip.

[0117] Specifically, the spring assembly mechanism 4 includes a spring feeding module 41, which includes a spring vibrator 411, a fifth lifting drive component 412 (which can be selected as a cylinder, hydraulic cylinder, electric cylinder, or linear module), a fifth horizontal drive component 413, a spring misalignment cylinder 414, a third lifting cylinder 415, a pushing cylinder 416, two spring gripper cylinders 417, and two spring channels. The spring vibrator 411 is used to accommodate the springs 1002 and can generate vibration to transport the springs 1002. The spring misalignment cylinder 414 divides the springs 1002 so that the springs 1002 enter the two spring channels respectively. When the springs 1002 reach the outlet of the spring channel, the pushing cylinder 416 pushes the springs 1002 into the two spring channels. The material cylinder 416 extends, and at the same time the spring gripper cylinder 417 opens. The material pushing cylinder 416 pushes the two springs 1002 to the two spring gripper cylinders 417 respectively. The driving end of the fifth lifting drive component 412 is provided with a guide block 418. The fifth lifting drive component 412 drives the guide block 418 to contact the spring 1002. The driving end of the third lifting cylinder 415 is provided with a magnetic suction rod 419. The third lifting cylinder 415 drives the magnetic suction rod 419 to pick up the spring 1002. The fifth horizontal drive component 413 drives the magnetic suction rod to reciprocate between the spring gripper cylinder 417 and the carrier 12 by driving the third lifting cylinder 415, so as to realize the transfer of the spring 1002 to the carrier 12.

[0118] The spring assembly mechanism 4 also includes a positioning module 42 located downstream of the spring feeding module 41. The carrier 12 is provided with a radial sliding member 1221 and an auxiliary pressure block 1222. The positioning module 42 includes a fourth lifting cylinder 421 and a positioning push block 422 located at the drive end of the fourth lifting cylinder 421. The fourth lifting cylinder 421 drives the positioning push block 422 to move upward, and the positioning push block 422 pushes the radial sliding member 1221 so that the radial sliding member 1221 pushes the auxiliary pressure block 1222 to compress the spring 1002 so that the spring 1002 is assembled in place.

[0119] Specifically, the base assembly mechanism 5 includes a belt conveyor module 51, a base transfer component 52, and a second flipping component 53. The base 1001 is conveyed by the belt conveyor module 51. The second flipping component 53 is used to grab two bases 1001 on the belt conveyor module 51 and flip the two bases 1001 180° so that the assembly slots face down. The base transfer component 52 grabs the two bases 1001 with the assembly slots facing down and places them in two second mounting positions 122 on the carrier 12 so that the button assembly and the spring 1002 are installed in the assembly slots.

[0120] The base transfer component 52 includes a sixth lifting drive 522 (selectable as a cylinder, electric cylinder, hydraulic cylinder, or linear module), a sixth horizontal drive 521 (selectable as a cylinder, electric cylinder, hydraulic cylinder, or linear module), a third pitch-changing drive 523 (selectable as a gripper cylinder, gripper hydraulic cylinder, or gripper electric cylinder), and two third gripper cylinders 524. The sixth horizontal drive 521 is mounted on the frame, the sixth lifting drive 522 is mounted on the drive end of the sixth horizontal drive 521, the third pitch-changing drive 523 is mounted on the drive end of the sixth lifting drive 522, and the two third gripper cylinders 524... The claw cylinders 524 are respectively disposed at the two driving ends of the third pitch-changing drive 523. The sixth lifting drive 522 can drive the two third claw cylinders 524 to lift and lower. The sixth horizontal drive 521 can drive the two third claw cylinders 524 to reciprocate between the second flipping component 53 and the carrier 12. The third pitch-changing drive 523 is used to drive the two third claw cylinders 524 to move closer or further away from each other to achieve pitch change. The third claw cylinders 524 are used to grip the base 1001 in the second flipping component 53 and place it in the second mounting position 122 of the carrier 12.

[0121] The second flipping component 53 includes a seventh horizontal drive member 531 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder, or linear module), a third rotary drive member 532 (which can be selected as a cylinder, hydraulic cylinder, or electric cylinder), and two fourth gripper cylinders 533. The seventh horizontal drive member 531 is mounted on the frame, the third rotary drive member 532 is located at the drive end of the seventh horizontal drive member 531, and the two fourth gripper cylinders 533 are located at the drive end of the third rotary drive member 532. The third rotary drive member 532 drives the two fourth grippers. The cylinder 533 rotates toward the belt conveyor module 51, the drive end of the seventh horizontal drive member 531 extends to drive the fourth gripper cylinder 533 to move, so that the fourth gripper cylinder 533 grips the base 1001, the third rotation drive member 532 drives the fourth gripper cylinder 533 to rotate 180°, the drive end of the seventh horizontal drive member 531 retracts, and the sixth lifting drive member 522 drives the third gripper cylinder 524 to descend, so that the third gripper cylinder 524 grips the base 1001 on the fourth gripper cylinder 533.

[0122] The base assembly mechanism 5 also includes a base clamping module 54 located downstream of the base transfer component 52. The base clamping module 54 includes two lifting drive components 541 (selectable as pneumatic, hydraulic, or electric cylinders) and two pressing drive components 543 (selectable as pneumatic, hydraulic, or electric cylinders). The lifting drive components 541 and pressing drive components 543 are spaced apart vertically and are both mounted on the frame. The driving end of the pressing drive component 543 is provided with a pressing block 544, and the driving end of the lifting drive component 541 is provided with a lifting block 542. The pressing drive component 543 drives the pressing block 544 to press against the base 1001, and the lifting drive component 541 drives the lifting block 542 to rise, thereby pressing the button assembly into the assembly slot of the base 1001. Furthermore, the driving end of the lifting drive component 541 is also provided with a sensing plate, which is used to detect whether the button assembly is properly assembled.

[0123] The limit switch core assembly equipment also includes a first detection mechanism 8, a waste rejection mechanism 9, and a first waste suction mechanism 10. The first detection mechanism 8 is located on the periphery of the conveying module 11 and downstream of the spring clip pressing module 232 in the spring clip assembly mechanism 23. The first detection mechanism 8 can detect whether the button assembly is installed in place, that is, whether the push rod 1003, connecting rod 1004, and spring clip 1006 are assembled in place. The waste rejection mechanism 9 is located on the periphery of the conveying module 11 and downstream of the base assembly mechanism 5. If the waste is lower than the detection mechanism, the waste will be rejected if it is located below the first detection mechanism 10. If the button assembly at mounting position 121 is not properly assembled, the rejection mechanism 9 can remove it. The first waste suction mechanism 10 is located on the periphery of the conveying module 11 and downstream of the rejection mechanism 9. Since the push rod 1003, connecting rod 1004 and spring 1006 on the first mounting position 121 are not properly assembled, the push rod 1003, connecting rod 1004 and spring 1006 are in a scattered state. When the rejection mechanism 9 cleans, it will be unable to clean properly. The first waste suction mechanism 10 can pick up the parts that the rejection mechanism 9 cannot clean and that remain.

[0124] Specifically, the first detection mechanism 8 includes a CCD camera 81 and a light source 82. Both the CCD camera 81 and the light source 82 are mounted on the frame. When the light source 82 is turned on, the CCD camera 81 takes a picture of the first mounting position 121 to detect whether the button assembly is installed in place.

[0125] Specifically, the rejecting mechanism 9 includes an eighth horizontal drive component 91 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder, or linear module), a seventh lifting drive component 92 (which can be selected as a cylinder, electric cylinder, hydraulic cylinder, or linear module), and four fifth gripper cylinders 93. The eighth horizontal drive component 91 is mounted on the frame, the seventh lifting drive component 92 is mounted on the drive end of the eighth horizontal drive component 91, and the four fifth gripper cylinders 93 are all mounted on the drive end of the seventh lifting drive component 92. The four fifth gripper cylinders 93 are paired up, and each pair of fifth gripper cylinders 93 corresponds to one of the two first mounting positions 121. Another set of fifth gripper cylinders 93 corresponds to two second mounting positions 122. The seventh lifting drive 92 drives the fifth gripper cylinders 93 to descend, so that the two sets of fifth gripper cylinders 93 respectively grab the unqualified button assembly located on the first mounting position 121 and the misassembled base 1001 and button assembly located on the second mounting position 122. The seventh lifting drive 92 drives the fifth gripper cylinders 93 to rise, and the eighth horizontal drive 91 drives the fifth gripper cylinders 93 to move to the top of the scrap box and put the unqualified button assembly and / or base 1001 into the scrap box.

[0126] Understandably, when the first inspection agency 8 detects that the button assembly located at the first mounting position 121 is unqualified, the unqualified button assembly will not be assembled with the base 1001 and will be rejected; the qualified button assembly will be transferred to the second mounting position 122 and assembled with the base 1001. If the assembly is not in place, it will be rejected.

[0127] Specifically, the first waste suction mechanism 10 includes an eighth lifting drive 101 and a vacuum generator 102. The eighth lifting drive 101 is mounted on the frame, and the vacuum generator 102 is located at the drive end of the eighth lifting drive 101. The vacuum generator 102 is equipped with a waste discharge pipe 103. The eighth lifting drive 101 can drive the vacuum generator 102 to descend, so that the vacuum generator 102 faces the carrier 12. The vacuum generator 102 generates a vacuum to suck in residual parts and discharge them through the waste discharge pipe 103, thereby achieving the purpose of cleaning the parts. It can be understood that when the first waste suction mechanism 10 is suctioning materials, the first pressure plate 1211 and the second pressure plate 1212 on the carrier 12 are opened under the action of the spreading mechanism 13.

[0128] Specifically, the second transfer mechanism 6 includes two fifth lifting cylinders 61, two fourth rotary drive members 62 (which can be selected as cylinders, electric cylinders or hydraulic cylinders), and two sixth gripper cylinders 63. The two fifth lifting cylinders 61 are mounted on the frame. The two fifth lifting cylinders 61 drive the two fourth rotary drive members 62 to lift and lower respectively. The two fourth rotary drive members 62 drive the two sixth gripper cylinders 63 to rotate respectively. When the two sixth gripper cylinders 63 grab the limit switch cores 100 (the limit switch cores 100 are formed after the base 1001 and the button assembly are assembled) on the two second mounting positions 122, the fourth rotary drive members 62 drive the corresponding sixth gripper cylinders 63 to rotate so that the assembly slots of the base 1001 face upwards, and the fifth lifting cylinders 61 descend so that the two limit switch cores 100 are placed in the two third mounting positions 123 respectively.

[0129] Specifically, the detection output mechanism 7 includes a continuity test mechanism 71, a second detection mechanism 72, a finished product handling mechanism 73, a second waste suction mechanism 74, and a third detection mechanism 75.

[0130] The continuity testing mechanism 71 is located downstream of the second transfer mechanism 6. The continuity testing mechanism 71 is used to test whether the electrical conductivity of the limit switch core 100 located at the third mounting position 123 is qualified. The second testing mechanism 72 is located downstream of the continuity testing mechanism 71. The second testing mechanism 72 is used to test whether the assembly of the limit switch core 100 located at the third mounting position 123 is qualified, that is, to finally test the entire limit switch core 100. The finished product handling mechanism 73 is located downstream of the second testing mechanism 72. The finished product handling mechanism 73 is used to place the limit switch core 100, whose electrical conductivity and assembly are both qualified, onto the good product flow channel 734 for output, and to transfer the electrical conductivity... Limit switch cores 100 with poor performance and / or assembly are placed on the waste flow channel 735 for output; the second waste suction mechanism 74 is located downstream of the finished product handling mechanism 73. The second waste suction mechanism 74 is used to clean up the parts remaining on the carrier 12. If the limit switch cores 100 are not assembled properly, parts are easily left on the carrier 12 during waste removal. The second waste suction mechanism 74 can clean up the remaining parts; the third detection mechanism 75 is located downstream of the second waste suction mechanism 74. The third detection mechanism 75 is used to detect whether the remaining parts on the carrier 12 have been completely cleaned. If they have been completely cleaned, the machine is started. If they have not been completely cleaned, the machine is stopped and manually cleaned.

[0131] Specifically, the continuity testing mechanism 71 includes a first testing mechanism 711 and a second testing mechanism 712 arranged sequentially. Both the first testing mechanism 711 and the second testing mechanism 712 are used to measure the electrical conductivity of the limit switch core 100 to ensure the accuracy of the test results. The first testing mechanism 711 and the second testing mechanism 712 have the same structural principle. Taking the first testing mechanism 711 as an example, the first testing mechanism 711 includes a sixth lifting cylinder 7111, a detection probe 7112 disposed at the drive end of the sixth lifting cylinder 7111, and two horizontal pushing cylinders 7113. The sixth lifting cylinder 7111 is disposed on the frame. The sixth lifting cylinder 7111 can drive the detection probe 7112 to move toward the carrier 12 so that the detection probe 7112 abuts against the stationary contact on the base 1001. The two horizontal pushing cylinders 7113 extend to press the two levers 1005 respectively to test the electrical conductivity of the limit switch core 100.

[0132] In this embodiment, the second detection mechanism 72 and the third detection mechanism 75 have the same structural principle as the first detection mechanism 8, and will not be described again here; the second waste suction mechanism 74 has the same structural principle as the first waste suction mechanism 10, and will not be described again here.

[0133] Specifically, the finished product handling mechanism 73 includes a ninth horizontal drive component 731 (which can be a cylinder, hydraulic cylinder, electric cylinder, or linear module), a ninth lifting drive component 732, and two seventh gripper cylinders 733. The ninth horizontal drive component 731 is mounted on the frame, the ninth lifting drive component 732 is mounted on the drive end of the ninth horizontal drive component 731, and the two seventh gripper cylinders 733 are mounted on the drive end of the ninth lifting drive component 732. The ninth lifting drive component 732 drives the two seventh gripper cylinders 733 to descend, and the two seventh gripper cylinders 733 grab the limit switch cores 100 on the two third mounting positions 123. The ninth horizontal drive component 731 drives the two seventh gripper cylinders 733 to move to the good product flow channel 734 and / or the waste material flow channel, so as to place the qualified limit switch cores 100 in the good product flow channel 734 for output and place the unqualified limit switch cores 100 in the waste material flow channel 735 for output.
