Similarly, when the extraction tray 11 on the receiving station is full, the receiving device 7 can automatically replace it with an empty extraction tray 11.

[0033] The material collecting device 7 mentioned above also includes a carrier plate 26, which is installed on the work surface 10 of the machine base 9. The corners of the carrier plate 26 are raised and together form an area B for positioning the collection tray 11. The defective products are collected by the collection tray 11 on the carrier plate 26. The material collecting device 7 mentioned above realizes the separate collection of defective products and good products.

[0034] like Figure 3 As shown, the specific structures of the loading robot 3 and the unloading robot 6 in this embodiment include: Servo motor 27, lead screw slider mechanism 28, guide rail slider assembly 29, motor 30, rocker arm 31, connecting rod 32, guide rail slider assembly 33 and vacuum nozzle assembly 1 34; Among them, the servo motor 27, the screw slider mechanism 28 and the guide rail slider assembly 29 are all installed on the slider of the one-to-many linear motor module 1 through the base plate 1 35.

[0038] like Figure 5 As shown, the specific structure of the material transfer robot 5 in this embodiment includes: Servo motor three 43, screw slider mechanism three 44, guide rail slider assembly four 45, three-axis cylinder 46 and vacuum nozzle assembly two 47; Among them, the servo motor three 43, the screw slider mechanism three 44 and the guide rail slider assembly four 45 are all installed on the slider of the one-to-many linear motor module 1 through the base plate four 48. The servo motor three 43 drives the slider of the guide rail slider assembly four 45 to reciprocate along the guide rail through the screw slider mechanism three 44. The three-axis cylinder 46 is installed on the slider of the guide rail slider assembly four 45 through the base plate five, and the vacuum nozzle assembly two 47 is installed on the cylinder rod of the three-axis cylinder 46.

[0039] Likewise, the structural design of the material transfer robot 5 is simple and reasonable, and the vacuum nozzle assembly 2 47 can have three translational degrees of freedom, corresponding to the X, Y and Z axis directions in the three-dimensional space coordinate system.

[0040] The electronic component electrical tester provided in this embodiment works as follows: Before starting the machine, manually place the full trays (filled with products) in a stack of trays 11 in any area A of the feeding device 2, which is called the full tray bin. The trays 11 are pressed on the support block 14, and the other area A is the empty tray bin. Place the empty trays (not loaded with products) in a stack of trays 11 in any area A of the receiving device 7, which is called the empty tray bin. The trays 11 are also pressed on the support block 14, and the other area A is the full tray bin. In addition, empty trays 11 are placed separately in area B of the carrier plate 26.

[0041] After starting up, first, the through-axis stepper motor 21 of the feeding device 2 drives the direct-acting mechanism 20 upward to lift the whole stack of the extraction tray 11 in the full tray bin. At this time, the whole stack of the extraction tray 11 is separated from the support block 14, and then the slide cylinder 13 drives the support block 14 to exit the square hole 12-1, and the through-axis stepper motor 21 drives the direct-acting mechanism 20 downward, and the whole stack of the extraction tray 11 moves downward accordingly. After the thickness of one extraction tray 11 is moved downward, the through-axis stepper motor 21 pauses, and the slide cylinder 13 drives the support block 14 to re-enter the square hole 12-1, and the support block 14 is inserted into the two layers. The through-axis stepper motor 21 then drives the direct-acting mechanism 20 to continue to descend in the gap between the extraction trays 11, and the bottom extraction tray 11 is separated from the entire stack of extraction trays 11. At this time, the carrier plate 19 is directly below the separated extraction tray 11, and when the extraction tray 11 falls on the area B of the carrier plate 19, the through-axis stepper motor 21 drives the direct-acting mechanism 20 to continue to descend until the direct-acting mechanism 20 avoids the carrier plate 19, and finally the servo motor 16 drives the carrier plate 19 to carry the extraction tray 11 to the feeding position, waiting for the loading robot 3 to absorb the product on the extraction tray 11.

[0042] After the products on the extraction tray 11 at the feeding position in the previous content are taken out, first, the servo motor 16 drives the carrier plate 19 carrying the extraction tray 11 with the empty tray to move to the bottom of the empty tray bin of the feeding device 2, and the slide cylinder 13 of the empty tray bin drives the support block 14 to exit the square hole 12-1, and then the through-axis stepper motor 21 drives the direct-acting mechanism 20 upward to lift the extraction tray 11 on the carrier plate 19 into the empty tray bin. When the extraction tray 11 is higher than the support block 14, the slide cylinder 13 drives the support block 14 to re-enter the square hole 12-1, and the support block 14 is inserted into the bottom of the extraction tray 11, and then the through-axis stepper motor 21 drives the direct-acting mechanism 20 to move downward, and the extraction tray 11 falls on the support block 14, completing the empty extraction tray 11 into the empty tray bin, and the through-axis stepper motor 21 drives the direct-acting mechanism 20 to continue to move downward until the direct-acting mechanism 20 avoids the carrier plate 19, and finally the servo motor 16 drives the carrier plate 19 to move again to the bottom of the full tray bin of the feeding device 2, ready to carry the next full extraction tray 11, and carry out the next cycle.

[0043] Synchronous with the content in the previous paragraph, after the leftmost loading robot 3 receives the signal that the full extraction tray 11 has reached the feeding position, the one-to-many linear motor module 1 first drives the loading robot 3 to move horizontally, and the servo motor 27 of the loading robot 3 drives the vacuum suction nozzle assembly 1 34 to move longitudinally until a pair of suction nozzles of the vacuum suction nozzle assembly 1 34 are aligned with a pair of products on the extraction tray 11, and then the motor 30 drives any suction nozzle downward through the rocker arm 31 and the connecting rod 32 until the suction nozzle sucks the product and then moves upward. At this time, the other suction nozzle also moves downward to absorb the second product, and then the motor 30 drives the vacuum suction nozzle assembly 1 34 to reset through the rocker arm 31 and the connecting rod 32, and then Then, the one-to-many linear motor module 1 drives the loading robot 3 to move again, and moves the two products to the top of the first test device 4. The servo motor 27 drives the vacuum nozzle assembly 34 to move longitudinally again, until a pair of products on the vacuum nozzle assembly 34 are aligned with the area C of the product seat 40, which we call the test position here. The motor 30 drives the vacuum nozzle assembly 34 again through the rocker arm 31 and the connecting rod 32 to place the products on the two test positions. This is repeated twice, and four products are placed on the four test positions. Finally, the multi-linear motor module 1 drives the loading robot 3 back to the top of the extraction tray 11 of the feeding position to prepare for the next material picking cycle.

[0044] After the four products in the previous paragraph are placed in the test position, the rotary cylinder 41 rotates first, and the four bosses of the product pressing block 42 are aligned with the four products and pressed down to lock the products. Then the slide cylinder 2 37 drives the bottom plate 3 39 of the integrated test probe 38 forward until the test probe 38 contacts the pin of the product for testing. According to the different functions of the electrical test machine, the corresponding test device 4 is arranged. Common test devices 4 include conduction tests, resistance tests, etc., and then after the test is completed, the slide cylinder 2 37 drives the bottom plate 3 39 of the integrated test probe 38 to reset again, and finally the rotary cylinder 41 resets to avoid the top of the product, waiting for the material transfer robot 5 to pick up the material and shift to the next test device 4.

[0045] After the four products in the previous paragraph complete a round of testing, first the one-to-many linear motor module 1 drives the material transfer robot 5 to move horizontally, and the servo motor three 43 of the material transfer robot 5 drives the vacuum nozzle assembly two 47 to move longitudinally until the four nozzles on the vacuum nozzle assembly two 47 are aligned with the products on the four test positions of the first test device 4, then the three-axis cylinder 46 drives the four nozzles downward to synchronously absorb the four products and then upward, and then the one-to-many linear motor module 1 drives the material transfer robot 5 to move again, and moves the four products to the top of the second test device 4, and the servo motor three 43 drives the vacuum nozzle assembly two 47 to move longitudinally again until the four products on the vacuum nozzle assembly two 47 are aligned with the four test positions of the second test device 4, and the three-axis cylinder 46 drives the vacuum nozzle assembly two 47 to place the four products on the four test positions, and finally the multi-linear motor module 1 drives the material transfer robot 5 back to the top of the first test device 4 to prepare for the next material picking cycle.

[0046] After the second round of testing in the previous section is completed, the one-to-many linear motor module 1 drives the unloading robot 6 to move to the top of the second test device 4. The unloading robot 6 takes out the product from the second test device 4 in the opposite way to the loading robot 3 in the previous text, and places it in the good product collection tray 11 and the defective product collection tray 11 of the receiving device 7 according to the test results. Because the proportion of defective products is very small, only one collection tray 11 is set, and an alarm is issued when it is full to prompt manual removal.

[0047] The action of the receiving device 7 is opposite to that of the feeding device 2 mentioned above. When the collecting tray 11 at the receiving position is full of materials, the servo motor 16 first drives the carrier plate 19 to move to the bottom of the full material bin, and the through-axis stepper motor 21 drives the direct-acting mechanism 20 to move upward. The direct-acting mechanism 20 lifts the full collecting tray 11. When the collecting tray 11 reaches the set height, the slide cylinder 13 drives the support block 14 to exit the square hole 12-1, and the direct-acting mechanism 20 lifts the collecting tray 11 to continue to move upward. After passing the height of the support block 14, the slide cylinder 13 drives the support plate 23 to enter the square hole 12-1 again, and the through-axis stepper motor 21 drives the direct-acting mechanism 20 to move downward, placing the extraction tray 11 on the support block 14, and the direct-acting mechanism 20 continues to move downward until the direct-acting mechanism 20 avoids the carrier plate 19, and then the servo motor 16 drives the carrier plate 19 to move to the bottom of the empty tray bin again, and the through-axis stepper motor 21 drives the direct-acting mechanism 20 upward to lift the entire stack of extraction trays 11 in the empty tray bin. At this time, the whole stack of extraction trays 11 are separated from the support block 14, and then the slide cylinder 13 drives the support block 14 to exit the square hole 12-1, and the through-axis stepper motor 21 drives the direct-acting mechanism 20 to move downward, and the whole stack of extraction trays 11 move downward accordingly. After the thickness of one extraction tray 11 is moved downward, the through-axis stepper motor 21 pauses, and the slide cylinder 13 drives the support block 14 to re-enter the square hole 12-1, and the support block 14 is inserted into the gap between the two layers of extraction trays 11, and then the through-axis stepper motor 21 drives The direct-acting mechanism 20 continues to descend, and the bottom layer of the extraction tray 11 is separated from the entire stack of extraction trays 11. At this time, the carrier plate 19 is directly below the separated extraction tray 11. When the extraction tray 11 falls on the area B of the carrier plate 19, the through-axis stepper motor 21 drives the direct-acting mechanism 20 to continue to descend until the direct-acting mechanism 20 avoids the carrier plate 19. Finally, the servo motor 16 drives the carrier plate 19 to carry the extraction tray 11 to the receiving position, waiting for the unloading robot 6 to place the product on the empty extraction tray 11.

[0048] This cycle repeats itself to complete the product loading, shifting, testing, and unloading operations.

[0049] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
