[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figures 1 to 12 As shown, the present invention provides a fully automatic testing machine for locators. In one embodiment, it includes a test transmission line 3; two carrier flipping devices 1 are arranged on one side of the test transmission line 3, and a test mechanism 4 and a test handling device 2 are arranged on the other side of the test transmission line 3; a defective product buffer rack is also arranged on one side of the test transmission line 3, and a defective product recycling station 5 is also installed on the defective product buffer rack; a buffer platform 313 is also installed on the test transmission line 3.

[0018] In this embodiment, the testing mechanism 4 can use existing testing equipment. During operation, the test transmission line 3 first transports the carrier carrying the locator to the area below one of the carrier flipping devices 1. At this time, the locator on the carrier is facing upwards (during testing, the carrier needs to be flipped so that the locator faces downwards before being placed into the testing equipment). The carrier flipping device 1 picks up the carrier and flips it 180° so that the locator faces downwards. Subsequently, the test transport device 2 picks up the carrier and transfers it into the testing equipment for testing. After the test is completed, the test transport device 2 transfers the carrier to another carrier flipping device 1. The carrier flipping device 1 flips the carrier back to its original position and then places it on the test transmission line 3. The test transmission line 3 then transports the carrier to the next process. At the same time, a defective product recycling station 5 is provided. If the test fails, the defective product can be transferred to the recycling station for unified recycling.

[0019] In one embodiment, the test transmission line 3 includes two test transmission racks 31; the two test transmission racks 31 are arranged in parallel and spaced apart, and a test transmission belt module is arranged on each side of the two test transmission racks 31; a motor drive module connected to the test transmission belt module is also installed on one of the test transmission racks 31; a material lifting mechanism 32 is arranged below one end between the two test transmission racks 31, and a lifting blocking mechanism 33 is arranged above the material lifting mechanism 32 on the top of the test transmission rack 31; a material unloading lifting mechanism 34 is arranged below the other end between the two test transmission racks 31; the material lifting mechanism 34 is arranged below the other end between the two test transmission racks 31. The mechanism 32 includes two incoming material connecting columns 321, and each incoming material connecting column 321 is connected to the bottom of a test transmission frame 31. An incoming material connecting plate 322 is also connected between the two incoming material connecting columns 321, and an incoming material lifting cylinder 323 is installed on one side of the incoming material connecting plate 322. The incoming material lifting cylinder 323 drives and connects to an incoming material lifting horizontal plate 324, and an incoming material lifting vertical plate 325 is connected to each of the top two ends of the incoming material lifting horizontal plate 324. An incoming material support plate 326 is connected to the upper part of each of the two incoming material lifting vertical plates 325 on opposite sides, and an incoming material positioning pin 327 is installed at each of the top two ends of the incoming material support plate 326.

[0020] In this embodiment, a gap is left between the test conveyor belt module and the test conveyor frame 31, through which the incoming material lifting vertical plate 325 is arranged. During operation, the test conveyor belt module connects to the carrier carrying the positioner, which is transported by the upstream conveyor line, and transports it to the incoming material lifting mechanism 32. Subsequently, the incoming material lifting cylinder 323 drives the incoming material lifting horizontal plate 324 to rise, so that the carrier is lifted off the test conveyor belt module by the incoming material support plate 326 on the incoming material lifting vertical plate 325. The lifting blocking mechanism 33 can limit its upward stroke. The lifting blocking mechanism 33 is moved away so that the carrier flipping device 1 can pick up the carrier and flip it. After the test is completed, the test transport device 2 transports the carrier to another carrier flipping device 1 (one carrier flipping device 1 is arranged near the incoming material lifting mechanism 32, and the other carrier flipping device 1 is arranged near the material lifting mechanism). The carrier flipping device 1 flips the carrier back to its original position and puts it back on the unloading lifting mechanism 34. The unloading lifting mechanism 34 then puts the carrier back on the test conveyor belt module. Finally, the test conveyor belt module transports the carrier to the next process.

[0021] In this embodiment, a material positioning pin 327 is installed at each of the top two ends of the material receiving pallet 326. Corresponding holes are provided on the carrier at the locations corresponding to the material positioning pins 327. When the carrier is lifted, the material positioning pins 327 will be inserted into the holes of the carrier to complete the quick positioning and ensure that the carrier is placed stably during the lifting process. In addition, a return transmission line 311 is arranged below the test transmission frame 31, and a buffer transmission line 312 is arranged on one side of one of the test transmission frames 31. The buffer platform 313 is installed on the buffer transmission line 312. The return transmission line 311 is used to connect to the return line in the unloading machine to return empty carriers for easy recycling. At the same time, if there are too many products to be tested, the carrier can be moved to the buffer transmission line 312 or the buffer platform 313 for buffering. When the testing equipment is idle, it can be moved to the testing equipment for testing. In addition, in order to improve work efficiency, in this embodiment, the material lifting mechanism 32 is provided with four sets.

[0022] In one embodiment, an incoming material blocking mechanism is also installed on the other side of the incoming material connecting plate 322; the incoming material blocking mechanism includes a first blocking cylinder 328 and a first blocking seat connected to the first blocking cylinder 328; a first blocking rod 329 extends upward from each of the top ends of the first blocking seat. After the carrier is transferred to the incoming material lifting mechanism 32, the first blocking cylinder 328 can drive the first blocking seat to rise, so as to stop the carrier via the first blocking rod 329, and then the incoming material lifting mechanism 32 lifts the carrier again.

[0023] In one embodiment, the lifting and blocking mechanism 33 includes a blocking fixing seat 331 connected to one side of one of the test transmission frames 31, a blocking translation cylinder 332 installed at one top end of the blocking fixing seat 331, and a blocking slide plate 333 slidably arranged on the top of the blocking fixing seat 331 and connected to the blocking translation cylinder 332; the top of the blocking slide plate 333 is also connected to a blocking pressure plate 334, and one end of the blocking pressure plate 334 is connected to a blocking pressure rod 335; the blocking pressure rod 335 is arranged above the test transmission belt module, and two blocking extension rods 336 extend outward from one side of the blocking pressure rod 335; each blocking extension rod 336 is correspondingly arranged above an incoming material tray 326.

[0024] After the carrier is transferred to the material lifting mechanism 32, the blocking translation cylinder 332 drives the blocking slide plate 333 to move, so that the blocking extension rod 336 on the blocking pressure plate 334 moves to above the material pallet 326. Then, the material lifting mechanism 32 will lift the carrier to the bottom of the blocking extension rod 336 to complete the Z-axis positioning. After that, the blocking extension rod 336 leaves, and the test transport device 2 will transfer the carrier into the test equipment. In this embodiment, the blocking pressure plate 334 is provided with four sets.

[0025] In one embodiment, the unloading lifting mechanism 34 includes two unloading connecting columns 341, and each unloading connecting column 341 is connected to the bottom of a test transmission frame 31. An unloading connecting plate 342 is also connected between the two unloading connecting columns 341, and an unloading lifting cylinder 343 is installed on one side of the unloading connecting plate 342. The unloading lifting cylinder 343 drives and connects to an unloading lifting horizontal plate 344, and a plurality of unloading lifting positions are spaced apart along the length of the top of the unloading lifting horizontal plate 344. Each unloading lifting position is connected to a unloading lifting vertical plate 345 at both ends, and an unloading support plate 346 is connected to the upper part of the opposite side of each of the two unloading lifting vertical plates 345. An unloading positioning pin is installed at each of the top ends of the unloading support plate 346. After the test is completed, the unloading lifting cylinder 343 drives the unloading lifting plate 344 to rise, so that the carrier flipping device 1 can place the flipped and reset carrier onto the unloading tray 346. Then, the unloading lifting plate 344 descends to put the carrier back onto the test conveyor belt module. In this embodiment, there are four unloading lifting positions.

[0026] In one embodiment, the test transmission line 3 further includes a material distribution mechanism 35 arranged at one end of the material lifting mechanism 32; the material distribution mechanism 35 includes a material distribution fixing plate 351 connected between the tops of the two test transmission frames 31; a material distribution translation cylinder 352 is installed at each of the top two ends of the material distribution fixing plate 351, and the material distribution translation cylinder 352 also drives a material distribution connecting vertical plate 353; the material distribution connecting vertical plate 353 is located above the test transmission frame 31, and a material distribution insert plate 354 is also connected to the lower part of one side of the material distribution connecting vertical plate 353; a material distribution insert block 355 extends outward from the middle of one side of the material distribution insert plate 354. Preferably, the material distribution block 355 has a triangular cross-section, and the two hypotenuses of the triangle have an inwardly concave arc shape. The material distribution translation cylinder 352 can drive the material distribution block 355 to be inserted between the carriers to achieve carrier division, so that the four carriers flow into the material lifting mechanism 32 as a group. In addition, a material blocking cylinder 36 is arranged below the two test transmission frames 31, and the material blocking cylinder 36 is located between the material distribution mechanism 35 and the material lifting mechanism 32.

[0028] The handling robotic arm 21 can be an existing robotic arm that can move, lift and rotate freely. At the same time, it is equipped with a first buffer spring, which can buffer the downward pressure on the carrier when the suction cup handling assembly picks up the transfer carrier to avoid crushing the product. In addition, in order to improve handling efficiency, in this embodiment, the test handling module 24 is provided with four sets.

[0029] Preferably, in this embodiment, the suction cup transport assembly includes a suction cup base 246 connected to the bottom of the slide rail lifting plate 243, and a suction cup pad 247 is connected to each of the two ends of the bottom of the suction cup base 246; a first transport suction cup 248 is also installed on the suction cup pad 247; a second transport suction cup 249 is also installed in the middle of the bottom of the suction cup base 246; and a transport positioning pin is also installed at the bottom of the suction cup pad 247.

The air source connector is connected to a negative pressure air source for ventilation, and the carrier suction cup 175 adsorbs the carrier; subsequently, the rotating... The translation mechanism 14 drives the rotating translation plate 15 to move the rack and pinion slide seat 16. During the movement of the rack and pinion slide seat 16, the first rack 161 drives the first gear 173 to rotate, which in turn drives the rotating spindle 172 to rotate, thereby driving the rotating adsorption seat 174 to rotate the carrier 180°, realizing the carrier rotation function (the locator is embedded in the corresponding slot of the carrier, and the carrier is made of elastic material, which will generate a certain clamping force on the locator to prevent it from falling off). In addition, in order to improve work efficiency, the rack and pinion slide seat 16 and the rotating adsorption mechanism 17 are both provided in four sets, that is, four carriers can be rotated at one time to meet the needs of modern production.
