That is, in the production process of photoelectric sensors, the transmitting tube and receiving tube need to be assembled onto the photoelectric sensor base by hand, and the assembled photoelectric sensor needs to be tested manually. As a result, the photoelectric sensor has the disadvantages of low assembly efficiency, low testing efficiency and high labor cost. Summary of the Invention

The seat feeding mechanism supplies the seat of the photoelectric sensor to the carrier in the feeding mechanism. The two diode feeding mechanisms are symmetrically arranged on the left and right sides of the feeding mechanism. The two diode feeding mechanisms are respectively used to insert the transmitting tube and receiving tube of the photoelectric sensor into the assembly holes located on both sides of the seat.

The two ends of the reset spring are fixed to the rotating seat and the second sliding seat, respectively. The third pneumatic finger is used to clamp the diode from the waste discharge station. The servo motor is used to drive the rotating seat, the second sliding seat, and the third pneumatic finger to rotate so that the diode on the third pneumatic finger is aligned with the mounting hole on one side of the seat body on the carrier. The fifth cylinder is used to push the second sliding seat so that the diode on the third pneumatic finger is inserted into the mounting hole on one side of the seat body. When the fifth cylinder releases the pushing state of the second sliding seat, the reset spring is used to drive the second sliding seat to slide and reset relative to the rotating seat.

[0011] In one possible implementation, the transfer assembly includes a first movable seat, a sixth cylinder, two seventh cylinders, and two clamping plates. The first movable seat is slidably connected to the frame. The sixth cylinder is horizontally fixed to the frame and is used to drive the first movable seat to reciprocate. Both seventh cylinders are fixed to the first movable seat. The two clamping plates are respectively fixed to the driving end of one of the seventh cylinders. The two seventh cylinders are used to drive the two clamping plates to move closer or further apart. When the two clamping plates move closer together and the first movable seat is driven to move by the sixth cylinder, the two clamping plates are used to clamp the diode located between the two clamping plates and drive the diode to move.

[0012] In one possible implementation, the feeding mechanism includes a clamping unit, a bending unit, a pushing unit, a detection unit, and a dispensing unit mounted on a frame. The clamping unit clamps the base body onto the support seat. The bending unit bends the two pins of the transmitting tube and the two pins of the receiving tube located on the base body. The pushing unit pushes the photoelectric sensor located on the support seat, causing the photoelectric sensor to be tested to move to the detection unit and extruding the tested photoelectric sensor into the dispensing unit.

Each conductive block assembly includes two conductive blocks fixed to the second movable seat at a front-to-back interval. When the tenth cylinder drives the second movable seat to move downward, the two conductive blocks located on the same side of the second movable seat are used to make contact with the two pins of the receiving tube or the two pins of the transmitting tube respectively for conductive contact.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] See Figures 1-15As shown in the embodiment of this application, a photoelectric sensor assembly device is disclosed, including a frame 1 and a feeding mechanism 2, a seat feeding mechanism 3, and two diode feeding mechanisms 4 connected to the frame 1. The seat feeding mechanism 3 is used to supply the seat 5 of the photoelectric sensor to the carrier 6 in the feeding mechanism 2. The two diode feeding mechanisms 4 are symmetrically arranged on the left and right sides of the feeding mechanism 2. The two diode feeding mechanisms 4 are respectively used to insert the transmitting tube and receiving tube in the photoelectric sensor into the assembly holes 51 located on both sides of the seat 5. The feeding mechanism 2 is used to detect the assembled photoelectric sensor and to separate the photoelectric sensors that are qualified and those that are unqualified.

[0021] The seat feeding mechanism 3 includes a seat feeding track 31, a moving unit 32, a clamping unit 33, and a detection unit 34. The seat feeding track 31 and the moving unit 32 are both connected to the frame 1. The clamping unit 33 and the detection unit 34 are both connected to the drive end of the moving unit 32. The clamping unit 33 is used to clamp the seat 5 located at the discharge end of the seat feeding track 31. The detection unit 34 is used to detect the orientation of the seat 5 clamped on the clamping unit 33. When the detection unit 34 detects an incorrect orientation of the seat 5 on the clamping unit 33... At the same time, the clamping unit 33 is used to drive the seat 5 to rotate horizontally so that the orientation of the seat 5 is adjusted to the correct state; the moving unit 32 is used to drive the clamping unit 33 and the detection unit 34 to move horizontally and vertically so that the clamping unit 33 places the seat 5 on the carrier seat 6; by adopting the above-mentioned seat feeding mechanism, it can automatically place the seat of the photoelectric sensor from the seat feeding track onto the carrier seat, and during the movement of the seat, it can automatically adjust the orientation of the seat to the correct state to realize the automated feeding of the seat.

[0022] The moving unit 32 includes a first cylinder 321, a first sliding seat 322, a second cylinder 323, and a bracket 324. The first cylinder 321 is horizontally fixed on the frame 1, the first sliding seat 322 is horizontally slidably connected to the frame 1, and the first sliding seat 322 is fixed to the drive end of the first cylinder 321. The second cylinder 323 is vertically fixed on the first sliding seat 322, and the bracket 324 is fixed on the drive end of the second cylinder 323. The clamping unit 33 and the detection unit 34 are both connected to the bracket 324. By adopting this moving unit, when the first cylinder drives the first sliding seat... When the frame slides horizontally, the first sliding seat can drive the second cylinder, the bracket, the clamping unit, and the detection unit to move horizontally. When the drive end of the second cylinder extends or retracts, the second cylinder can drive the bracket, the clamping unit, and the detection unit to move vertically. That is, the moving unit can reliably drive the clamping unit and the detection unit to move horizontally and vertically. The clamping unit 33 includes a first rotary clamping cylinder 331, which is vertically fixed on the bracket 324. By using this clamping unit, when the detection unit detects the seat on the clamping unit... When the orientation is incorrect, the clamping unit can rotate the seat horizontally to adjust the orientation of the seat to the correct state. In this embodiment, when the orientation of the seat is incorrect, the first rotary clamping cylinder can rotate the seat horizontally to swap the two ends of the seat. The detection unit 34 includes a third cylinder 341, a detection rod 342, a photoelectric switch 343, and a trigger plate 344. The third cylinder 341 is vertically fixed on the bracket 324, the detection rod 342 is vertically fixed on the drive end of the third cylinder 341, the photoelectric switch 343 is fixed on the side wall of the detection rod 342, and the trigger plate 344... A probe block 3421 is provided on the inner side of the lower end of the probe rod 342, which is fixed on the bracket 324. When the third cylinder 341 drives the probe rod 342 to move downward so that the probe block 3421 is embedded in the notch 52 located at one end of the base 5, the trigger piece 344 is used to trigger the photoelectric switch 343. When the third cylinder 341 drives the probe rod 342 to move downward so that the probe block 3421 abuts against the protrusion 53 located at the other end of the photoelectric sensor base 5, the protrusion 53 is used to block the probe rod 342 from moving downward so that the trigger piece 344 cannot trigger the photoelectric switch 343.With this structure, while the clamping unit clamps the seat located at the discharge end of the seat feeding track, the third cylinder drives the probe rod downwards. When the probe block is embedded in the notch at one end of the seat, the trigger plate triggers the photoelectric switch. At this time, the photoelectric switch sends a trigger signal to the controller, indicating that the orientation of the photoelectric sensor seat is correct. If the probe block is abutting against the protrusion, the trigger plate cannot trigger the photoelectric switch, and the photoelectric switch cannot send a trigger signal to the controller, indicating that the orientation of the photoelectric sensor seat is incorrect. Thus, during the subsequent movement of the clamping unit driven by the moving unit, the clamping unit can adjust the orientation of the seat to the correct state. In this embodiment, when the orientation of the photoelectric sensor seat is incorrect, the first rotary clamping cylinder can drive the seat to rotate horizontally so that the two ends of the seat are interchanged.

[0023] Each diode loading mechanism 4 includes a loading station 41, a lead cutting station 42, an inspection station 43, a direction adjustment station 44, a waste removal station 45, and a pushing station 46, sequentially connected to the frame 1. A transfer assembly 47 is also connected to the frame 1. The transfer assembly 47 is used to synchronously transfer diodes from one station to the next. The lead cutting station 42 is used to cut the leads of the diodes. The inspection station 43 is used to determine the quality and polarity of the diodes. The direction adjustment station 44 is used to adjust the polarity of the diodes. The waste removal station 45 is used to remove damaged diodes. The feeding station 46 is used to insert diodes into the assembly holes 51 located on one side of the housing 5. By adopting the diode feeding mechanism described above, the diodes can be automatically fed and assembled onto the housing of the photoelectric sensor, thereby improving the assembly efficiency of the photoelectric sensor and reducing labor costs. At the same time, the detection station can detect the quality of the diodes, so that damaged diodes can be discharged in time through the waste discharge station to prevent damaged diodes from flowing into subsequent stations, thereby improving the quality of the photoelectric sensor formed by assembling the diodes and the housing.

[0024] The loading station 41 includes a diode feeding track 411, a fourth cylinder 412, and a first top block 413. Both the diode feeding track 411 and the fourth cylinder 412 are fixed to the frame 1. The first top block 413 is located at the discharge end of the diode feeding track 411 and is fixed to the drive end of the fourth cylinder 412. When the fourth cylinder 412 drives the first top block 413 to move upward, the first top block 413 pushes the first diode located at the discharge end of the diode feeding track 411 upward. With this loading station, when the fourth cylinder drives the first top block to move upward, the first top block can push the first diode located at the discharge end of the diode feeding track upward; when the fourth cylinder drives the first top block to move downward, it resets. Subsequently, the next diode from the diode feeding track can reach the position of the first top block, thus enabling the diodes to be fed one by one when the fourth cylinder drives the first top block to move downward. In addition, the feed end of the diode feeding track is connected to the vibrating feeding tray storing diodes. The lead cutting station 42 includes two cutters 421, the inspection station 43 includes two first clamps 431, and a first pneumatic finger 48 is fixed on the frame 1. The two cutters 421 and the two first clamps 431 are symmetrically fixed on the two drive ends of the first pneumatic finger 48. Two conductive pins 4311 are arranged at left and right intervals on one of the first clamps 431, and both conductive pins 4311 are electrically connected to the controller. When the two driving ends of the first pneumatic finger 48 approach each other, the two cutters 421 are used to cut the two leads of the diode, the two first clamps 431 are used to clamp the two leads of the diode, and the two conductive pins 4311 are respectively used to contact one of the leads of the diode for conductivity. By adopting this lead cutting station and inspection station, when the two driving ends of the first pneumatic finger approach each other, the two cutters can cut the two leads of the diode, that is, the excess part of the diode leads can be removed. At the same time, the two first clamps can clamp the two leads of the diode at the corresponding station, and the two conductive pins can respectively contact one of the leads of the diode for conductivity. When the inspection station is conducting... When testing a diode, a forward voltage is first applied to the diode, followed by a reverse voltage. If the diode is either conducting or cut off during the two tests, it is considered good. If the diode is either cut off or conducting in both tests, it is faulty. The diode's orientation can be determined based on the order of conduction and cutoff during the testing process. The orientation adjustment station 44 includes a second rotary clamping cylinder 441 fixed on the frame 1. The second rotary clamping cylinder 441 is used to clamp the diode from the testing station 43. When the testing station 43 determines that the diode's polarity orientation is incorrect, it rotates the diode to reverse the positions of the two pins.By employing this orientation adjustment station, the second rotary clamping cylinder can clamp the diode from the inspection station. When the inspection station determines the diode's polarity is incorrect, it can rotate the diode to swap the positions of its two pins, thus correcting the diode's orientation. The waste removal station 45 includes a second pneumatic finger 451 fixed to the frame 1 and a waste removal pipe 452. The second pneumatic finger 451 clamps and temporarily stores the diode from the orientation adjustment station 44. When the inspection station 43 determines the diode is faulty, the second pneumatic finger 451 releases the diode, causing it to fall into the waste removal pipe 452. This waste removal station prevents damaged diodes from flowing into subsequent stations when the inspection station determines the diode is faulty. If the inspection station determines the diode is undamaged, the second pneumatic finger can clamp the diode and temporarily store it.

[0025] The feeding station 46 includes a servo motor 461, a rotating seat 462, a second sliding seat 463, a third pneumatic finger 464, a fifth cylinder 465, and a return spring 466. The servo motor 461 and the fifth cylinder 465 are both fixed to the frame 1. The rotating seat 462 is fixed to the output shaft of the servo motor 461. The second sliding seat 463 is slidably connected to the rotating seat 462. The third pneumatic finger 464 is fixed to the second sliding seat 463. The two ends of the return spring 466 are respectively fixed to the rotating seat 462 and the second sliding seat 463. The third pneumatic finger 464 is used to clamp the diode from the waste discharge station 45. The servo motor 461 is used to drive the rotating seat 462, the second sliding seat 463, and the third pneumatic finger 464 to rotate so that the diode located on the third pneumatic finger 464 is aligned with the mounting hole 51 on one side of the seat 5 on the support seat 6. The fifth cylinder 465 is used to push the second sliding seat 463 to align the diode located on the third pneumatic finger 464 with the mounting hole 51 on one side of the seat 5 on the support seat 6. The diode on finger 464 is inserted into the mounting hole 51 on one side of the base 5. When the fifth cylinder 465 releases the pushing state of the second sliding seat 463, the reset spring 466 drives the second sliding seat 463 to slide and reset relative to the rotating seat 462. After adopting this pushing station, after the third pneumatic finger clamps the diode from the waste discharge station, the servo motor can drive the rotating seat, the sliding seat and the third pneumatic finger to rotate so that the diode on the third pneumatic finger is aligned with the mounting hole on one side of the base on the carrier. Then, the fifth cylinder can push the sliding seat so that the diode on the third pneumatic finger is inserted into the mounting hole on one side of the base. Subsequently, the third pneumatic finger releases the diode and the fifth cylinder releases the pushing state of the sliding seat. At this time, the reset spring can drive the sliding seat to slide and reset relative to the rotating seat. Finally, the servo motor can drive the rotating seat, the sliding seat and the third pneumatic finger to rotate and reset.

[0026] The material transfer assembly 47 includes a first movable seat 471, a sixth cylinder 472, two seventh cylinders 473, and two clamping plates 474. The first movable seat 471 is slidably connected to the frame 1. The sixth cylinder 472 is horizontally fixed to the frame 1 and is used to drive the first movable seat 471 to reciprocate. Both seventh cylinders 473 are fixed to the first movable seat 471. The two clamping plates 474 are respectively fixed to the driving end of one of the seventh cylinders 473. The two seventh cylinders 473 are used to drive the two clamping plates 474 to move closer or further apart. When the two clamping plates 474 move closer together and are driven by the sixth cylinder 473, the material transfer assembly 474 moves forward and backward. When cylinder 472 drives the first moving seat 471 to move, two clamping plates 474 are used to clamp the diode located between the two clamping plates 474 and drive the diode to move. By adopting this material transfer assembly, when the two seventh cylinders drive the two clamping plates to move closer to each other and the sixth cylinder drives the moving seat to move, the two clamping plates can clamp the diode located between the two clamping plates and drive the diode to move. In the above process, the two clamping plates can clamp the diodes in multiple stations at the same time and drive the diodes in multiple stations to move synchronously to the next station, that is, the step-by-step movement of the diode is realized.

[0027] The feeding mechanism 2 includes a clamping unit 21, a bending unit 22, a pushing unit 23, a detection unit 24, and a sorting unit 25 mounted on the frame 1. The clamping unit 21 clamps the base 5 onto the support base 6. The bending unit 22 bends the two pins of the transmitting tube and the two pins of the receiving tube located on the base 5. The pushing unit 23 pushes the photoelectric sensor located on the support base 6, causing the photoelectric sensor to be tested to move to the detection unit 24 and extruding the tested photoelectric sensor into the sorting unit 25. The detection unit 24 detects the quality of the transmitting tube and the receiving tube. The sorting unit 25 sorts the photoelectric sensors that pass the test and those that fail. By adopting the above feeding mechanism, the photoelectric sensor can be automatically tested, and the qualified and unqualified photoelectric sensors can be sorted. This improves the testing efficiency and production efficiency of the photoelectric sensor, while also reducing labor costs.

[0028] The clamping unit 21 includes a tilting cylinder 211 and a second clamping block 212. The tilting cylinder 211 is horizontally fixed on the frame 1, and the second clamping block 212 is fixed on the drive end of the tilting cylinder 211. A backing part 61 is provided on the front side of the bearing seat 6. The tilting cylinder 211 is used to drive the second clamping block 212 to tilt so that the second clamping block 212 and the backing part 61 cooperate to clamp the seat body 5. By adopting this clamping unit, when the tilting cylinder drives the second clamping block to tilt, the second clamping block can cooperate with the backing part to clamp the seat body. When the tilting cylinder drives the second clamping block to tilt back, the second clamping block can be tilted back to reset and release the clamping of the seat body. State; the bending unit 22 includes two eighth cylinders 221 and two second top blocks 222; the two eighth cylinders 221 are symmetrically fixed on the frame 1 located on the left and right sides of the support 6, and both eighth cylinders 221 are inclined; the two second top blocks 222 are respectively fixed on the drive end of one of the eighth cylinders 221; when the two eighth cylinders 221 push the two second top blocks 222, the two second top blocks 222 are respectively used to push the two pins of the transmitting tube and the two pins of the receiving tube, so that the two pins of the transmitting tube and the two pins of the receiving tube are bent; by adopting this bending unit, the seat body is clamped unit In the clamped state, when the two eighth cylinders drive the two second push blocks, the two second push blocks can respectively push the two pins of the transmitting tube and the two pins of the receiving tube, so that the two pins of the transmitting tube and the two pins of the receiving tube are bent, that is, the two pins of the transmitting tube and the two pins of the receiving tube are bent to the required angle, generally so that after the two pins of the transmitting tube and the two pins of the receiving tube are bent, they are in a state perpendicular to the base; the pushing unit 23 includes a ninth cylinder 231 and a push block 232; the ninth cylinder 231 is fixed on the frame 1, and the push block 232 is fixed on the driving end of the ninth cylinder 231. When the ninth cylinder 231 pushes the pusher block 232, the pusher block 232 pushes the seat 5 located on the support seat 6, so that the photoelectric sensor to be tested moves to the detection unit 24 and the photoelectric sensor that has been tested is squeezed out into the material distribution unit 25. By adopting this pusher unit, after the clamping unit releases the clamping state of the seat, and when the ninth cylinder pushes the pusher block, the pusher block can push the seat located on the support seat after the assembling of the transmitting tube and the receiving tube, so that the photoelectric sensor to be tested moves to the detection unit. At the same time, the photoelectric sensor that was originally located at the detection unit and has been tested by the detection unit is squeezed out into the material distribution unit.

[0029] The detection unit 24 includes a tenth cylinder 241 and a second movable seat 242. The tenth cylinder 241 is fixed on the frame 1 and is used to drive the second movable seat 242 to move up and down relative to the support seat 6. The second movable seat 242 is fixed on the drive end of the tenth cylinder 241. Conductive block assemblies are fixed on the outer walls of both sides of the second movable seat 242. Each conductive block assembly includes two conductive blocks 243 fixed on the second movable seat 242 at a distance from each other. When the tenth cylinder 241 drives the second movable seat 242 to move downward, the two conductive blocks 243 located on the same side of the second movable seat 242 are used to connect with the two leads of the receiving tube. The two pins of the receiver or transmitter are respectively in conductive contact; both conductive block assemblies are electrically connected to the controller; by adopting this detection unit, when the tenth cylinder drives the second moving seat downward, the two conductive blocks located on the same side of the second moving seat can respectively make conductive contact with the two pins of the receiver or transmitter. When the controller detects the receiver and transmitter, it first applies a positive voltage to the receiver and transmitter, then applies a reverse voltage. If, during both detection processes, the receiver and transmitter exhibit a situation of one conduction and one cutoff, it indicates that the receiver and transmitter are good. If both the receiving and transmitting tubes are either cut off or conductive during the two tests, then the receiving and transmitting tubes are faulty. Furthermore, if either the receiving or transmitting tube is damaged during the above testing process, the photoelectric sensor is deemed a defective product.

Below 251 and fixed to the drive end of rotary cylinder 254, the first feeding hopper 252 and the second feeding hopper 253 are located on the left and right sides of guide plate 255 respectively and are both fixed to the lower end of frame 1; when rotary cylinder 254 drives guide plate 255 to rotate to one side, guide plate 255 is used to guide photoelectric sensors that have been detected as qualified by detection unit 24 from guide pipe 251 to first feeding hopper 252; when rotary cylinder 254 drives guide plate 255 to rotate to the other side, guide plate 255 is used to guide photoelectric sensors that have been detected as unqualified by detection unit 24 from guide pipe 251 to second feeding hopper 253.By employing this material distribution unit, when the detection unit detects a qualified photoelectric sensor, the rotary cylinder drives the guide plate to rotate to one side. Thus, during the subsequent pushing unit's movement of the base, the qualified photoelectric sensor is guided by the guide tube and guide plate to fall into the first hopper. When the detection unit detects a defective photoelectric sensor, the rotary cylinder drives the guide plate to rotate to the other side. Thus, during the subsequent pushing unit's movement of the base, the defective photoelectric sensor is guided by the guide tube and guide plate to fall into the second hopper.

[0030] In this embodiment, two diode feeding mechanisms are used to insert the transmitting tube and receiving tube of the photoelectric sensor into the assembly holes located on both sides of the base. That is, one diode feeding mechanism is used to insert the transmitting tube into the assembly hole located on one side of the base, and the other diode feeding mechanism is used to insert the receiving tube into the assembly hole located on the other side of the base. Since the two diode feeding mechanisms are symmetrically arranged on the left and right sides of the unloading mechanism, for ease of description, in this embodiment, the transmitting tube and the receiving tube are collectively referred to as diodes.
