[0002] Neon lamp is a neon sign lamp. A neon lamp tube is a sealed glass tube with electrodes at both ends, which is filled with some low-pressure gas. During the production process, the neon lamp needs to be aged. The aging process is to insert the neon bulb into the aging machine for electronic activation and aging, in order to make the neon bulb glow stably. During the aging process, the neon lamp needs to be tested and screened to prevent defective neon filaments from entering the market.

[0003] In the existing screening process, large quantities of neon lamps are often tested one by one manually in an electric environment. The testing process is time-consuming and labor-intensive, with low testing efficiency. In addition, manual testing is prone to errors, making it difficult to quickly and comprehensively test and screen large quantities of neon lamps. Summary of the invention

It should be noted that the length of each material distribution channel only allows one neon lamp to pass through, so that the neon lamp can be transported downward along the material distribution channel in an orderly manner; columns 25 are connected to both sides of the material distribution frame 22, and the two columns 25 are connected to The extension plate 26 is located above the second vibration plate 23.

The second slide 283 is slidably connected to the second guide rod, and the mounting platform 271 is fixed on the second slide 283. When the third motor 282 is started to drive the second screw rod 281 to rotate, the second slide 283 can be driven to move along the second guide rod, thereby driving the material suction mechanism 27 to move.

[0041] like Figure 7As shown, the suction mechanism 27 includes a mounting platform 271, a first motor 272 fixed on the mounting platform, a first bevel gear 273 connected to the first motor through a coupling, a rotating shaft 274 rotatably connected to one end of the mounting platform, and a second bevel gear 275 connected to the rotating shaft.

Through the operation of the negative pressure fan, negative pressure is generated at the suction nozzle 279. The suction nozzle 279 is used to absorb the neon lamp bulb, and then the first motor 272 is started. Through the cooperation of the first bevel gear 273 and the second bevel gear 275, the rotating shaft 274 is driven to rotate. The rotating shaft 274 drives the mounting frame 276 to rotate, thereby driving the neon lamp to rotate so that the conductive wire of the neon lamp faces the electric plug 12, and then the second linear displacement mechanism 28 drives the suction mechanism to move toward the electric plug 12 to insert the conductive wire on the neon lamp into the electric plug 12.

[0042] like Figure 2-5 As shown, the sorting mechanism 3 includes a plurality of groups of sorting units connected to both sides of the belt conveyor, and each group of sorting units includes a first U-shaped frame 31 and a second U-shaped frame 32 connected to both sides of the belt conveyor 11. The bottom surface of the first U-shaped frame 31 is connected to a plurality of color temperature testers 33 corresponding to the electric plugs, and a detection probe 34 is installed on the bottom surface of the color temperature tester 33. The second U-shaped frame 32 is connected to a grasping mechanism 35 through a first linear displacement mechanism 37. A dividing hopper 36 inclined downward and outward is connected to one side of the grasping mechanism 35 on the belt conveyor 11. A through hole is provided at the lower part of the second U-shaped frame 32, and the dividing hopper 36 passes through the through hole, and the upper end of the dividing hopper 36 is located below one side of the grasping mechanism, and the defective neon lamp is grasped to the dividing hopper 36 through the grasping mechanism.

[0043] The first linear displacement mechanism 37 includes a first screw rod 371 rotatably connected to the two second U-shaped frames, a first guide rod connected to the two second U-shaped frames, a first slide 372 threadedly connected to the first screw rod, and a second motor 373 installed on one side of the second U-shaped frame. The second motor 373 is transmission-connected to the first screw rod 371, and the first slide 372 is slidably connected to the first guide rod. The grabbing mechanism 35 is installed on the first slide 372. The grabbing mechanism 35 includes a first cylinder 351 connected to the bottom surface of the first slide, a connecting plate 352 connected to the telescopic end of the first cylinder, a second cylinder 353 connected to the connecting plate, a finger cylinder 354 connected to the bottom surface of the second cylinder, a first position sensor 355 connected to the top surface of the connecting plate, and a second position sensor 356 connected to the bottom surface of the color temperature tester and matched with the first position sensor. The first cylinder 351 can extend to drive the connecting plate 352 to the bottom of the color temperature tester 33.

[0044] When the color temperature tester 33 and the detection probe 34 detect that the neon lamp is defective, that is, the color temperature is unqualified, the signal is transmitted to the controller, and the controller controls the belt conveyor 11 to stop working, and then controls the first cylinder 351 to extend, driving the connecting plate 352 to move toward the first U-shaped frame 31. Through the cooperation of the first position sensor 355 and the second position sensor 356, the connecting plate 352 accurately reaches the bottom of the color temperature tester 33, and then controls the second cylinder 353 to extend, driving the finger cylinder 354 to descend, and grab the defective neon lamp through the finger cylinder 354, and then controls the second cylinder 353 to contract, and the first cylinder 351 to contract, so that the finger cylinder 354 leaves the first U-shaped frame 31, and then starts the second motor 273 to drive the first screw rod 371 to rotate. During the rotation of the first screw rod 371, the first slide seat 372 is driven to move, thereby driving the grabbing mechanism 35 to move toward the dividing hopper 36, so as to put the grabbed defective neon lamp on the dividing hopper 36 and discharge it through the dividing hopper. It should be noted that several groups of sorting units are arranged on the belt conveyor to improve the accuracy of detection.

[0045] Specifically, the unloading mechanism 4 includes a crossbeam 41 connected to the lower end of the belt conveyor, and a discharge hopper 42 connected to the belt conveyor and located below the crossbeam. The crossbeam 41 is provided with a plurality of notches 43 that match the electric plug, and the neon lamps are scraped off into the discharge hopper 42 through the notches. After the neon lamps are plugged into the electric plug 12, the neon lamps are conveyed forward by the belt conveyor 11. After the defective neon lamps are sorted, the normal neon lamps arrive at the crossbeam 41, and then the neon lamps enter the notches 43, and the neon lamps are scraped off through the notches 43 and fall into the discharge hopper 42, so that the normal neon lamps are collected.

[0046] An electrical cabinet 5 is provided on one side of the belt conveyor, and a controller is provided in the electrical cabinet. The color temperature tester, the detection probe, the first position sensor, the second position sensor, the first motor, the second motor, the third motor, the first cylinder, the second cylinder, the third cylinder, and the finger cylinder are all electrically connected to the controller.

[0047] The working principle of this embodiment is:

[0048] A large number of neon lamps are placed in the first vibration plate, and the neon lamps are sent to the second vibration plate through the first vibration plate, and enter the distribution channel in turn. Through the action of the second vibration plate, the neon lamps move downward in the distribution channel. Due to the heavy weight of the neon bulb head of the neon lamp, the neon bulb head will gradually move downward in the second vibration plate. When the neon lamp reaches the end of the distribution channel, the suction mechanism is driven to move toward the distribution channel through the second linear displacement mechanism. At the same time, the negative pressure fan works to generate negative pressure, and the neon bulb head of the neon lamp is adsorbed by the suction nozzle. Then the first motor is started, and the shaft is driven to rotate through the cooperation of the first bevel gear and the second bevel gear, so that the suction nozzle rotates 360 degrees, so that the conductive wire of the neon lamp faces the electric plug, and then the suction mechanism is driven to move toward the belt conveyor through the second linear displacement mechanism to insert the conductive wire into the electric plug. Then the negative pressure fan stops working, and the suction nozzle is separated from the neon lamp, so that the neon lamp is installed on the electric plug.

[0049] After the neon lamp is installed on the electric plug, the neon lamp is conveyed forward in sequence by the belt conveyor. When passing through the first U-shaped frame of the sorting unit, the color temperature of the neon lamp is detected by the color temperature tester and the detection probe. If the color temperature is qualified, the belt conveyor continues to work. If the color temperature is unqualified, the signal is transmitted to the controller, and the controller controls the belt conveyor 11 to stop working, and then controls the first cylinder 351 to extend, driving the connecting plate 352 to move toward the first U-shaped frame 31. Through the cooperation of the first position sensor 355 and the second position sensor 356, the connecting plate 352 accurately reaches the color temperature tester. The second cylinder 353 is controlled to extend below the instrument 33, and then the finger cylinder 354 is controlled to descend, and the defective neon lamp is grabbed by the finger cylinder 354, and then the second cylinder 353 is controlled to contract, and the first cylinder 351 is contracted to make the finger cylinder 354 leave the first U-shaped frame 31, and then the second motor 273 is started to drive the first screw rod 371 to rotate, and the first screw rod 371 drives the first slide 372 to move during the rotation process, thereby driving the grabbing mechanism 35 to move toward the distribution hopper 36, so as to put the grabbed defective neon lamp on the distribution hopper 36, and discharge it through the distribution hopper. In this way, after passing through multiple sorting units, all defective neon lamps can be found. After the sorting is completed, the normal neon lamp continues to be transported forward by the belt conveyor 11, and the neon lamp reaches the crossbeam 41, and then the neon lamp enters the gap 43, and the neon lamp is scraped off through the gap 43 and falls into the discharge hopper 42, so as to collect the normal neon lamp.

[0050] The dehumidification machine body described in this embodiment is prior art, and this application will not describe the specific structure and principle in detail.

[0051] Example 2

[0052] The difference between this embodiment and the embodiment 1 is that a material blocking mechanism 29 is provided at the end of the material distribution channel 24, and the material blocking mechanism 29 includes an L-shaped frame 291 installed on the bottom surface of one end of the second vibration plate, a third cylinder 292 installed on the L-shaped frame, a lifting plate 293 connected to the telescopic end of the third cylinder, and a plurality of baffles 294 connected to the lifting plate and matched with the material distribution channel. The end of the material distribution channel 24 is provided with an opening, and the baffle 294 is movably arranged in the opening. When the third cylinder 292 works, it can drive the baffle 294 to rise and fall in the opening. When the neon lamp moves downward in the material distribution channel, the baffle can prevent the neon lamp from falling off the second vibration plate. When the suction nozzle is ready to absorb the neon lamp, the third cylinder is controlled to contract to drive the baffle to descend so that the suction nozzle can absorb the neon lamp.
