[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0032] An automatic electrical measuring machine, such as Figure 1 and Figure 2As shown, it includes a machine 1, on which an electric measuring mechanism 3, a feeding mechanism 4, a positioning mechanism 5, a defective product collecting mechanism 6, a pressing mechanism 7 and two picking and placing mechanisms 2 are provided. The two picking and placing mechanisms 2 are respectively arranged at the two ends of the machine 1. The picking and placing mechanism 2 located at the front end is used to convey the material tray full of the product to be tested so that the feeding mechanism 4 can absorb the product for electric measuring treatment, and collect and sort the empty material tray for storage. The picking and placing mechanism 2 located at the rear end is used to convey the empty material tray to receive the product that has passed the electric property test, and collect and store the full material tray. The electric measuring mechanism 3 is arranged in the middle of the machine 1, and is used to energize the product and detect whether the product's electrical properties meet the requirements. The positioning mechanism 5 is arranged between the picking and placing mechanism 2 located at the front end and the electric measuring mechanism 3, and is used to detect the position and direction of the product sucked on the feeding mechanism 4, so that the feeding mechanism 4 can be adjusted to fit the detection position on the electric measuring mechanism 3. The defective product collecting mechanism 6 is arranged between the picking and placing mechanism 2 located at the rear end and the electric measuring mechanism 3, and is used to place defective products. The feeding mechanism 4 is arranged beside the alignment mechanism 5 and the electrical measuring mechanism 3, so as to facilitate the clamping of the product on the front unloading mechanism for position identification and placement on the electrical measuring mechanism 3 for testing. The pressing mechanism 7 is arranged corresponding to the electrical measuring mechanism 3, and when the electrical measuring mechanism 3 performs electrical testing on the product, the pressing mechanism 7 presses the product to prevent its position from changing.

[0033] Specifically, Figure 1 and Figure 2 As shown, the material taking and discharging mechanism 2 at the front end conveys the material tray filled with the product to be tested, and the feeding mechanism 4 absorbs the product and carries it to the alignment mechanism 5 to identify the position and direction of the product. The feeding mechanism 4 adjusts according to the product position and direction identified by the alignment mechanism 5, so that the product fits the detection position of the electrical measuring mechanism 3, and places the product to be tested on the electrical measuring mechanism 3. The pressing mechanism 7 presses the product to keep the product position unchanged on the electrical measuring mechanism 3. The electrical measuring mechanism 3 contacts the product and energizes to detect the electrical properties of the product. If the product is qualified, the product is transferred to the empty material tray of the material taking and discharging mechanism 2 at the rear end. The material taking and discharging mechanism 2 at the rear end sorts and collects the material trays, and unqualified products are sent to the defective product collection mechanism 6 for collection. In this way, it can be avoided that the product moves during the electrical property detection process and causes the detection to be in place, which is conducive to improving the detection accuracy, and the product trays can be automatically collected, sorted and stored, reducing manual operations, which is conducive to reducing production costs.

[0034] An automatic electrical measuring machine provided in this embodiment, such as Figure 3 and Figure 4As shown, the electrical testing mechanism 3 includes an electrical testing base 31, an electrical testing bearing assembly 32, an electrical testing assembly 34 and an electrical testing transport assembly 33. Several of the electrical testing bearing assemblies 32 are arranged side by side below the electrical testing base 31, and are used to transfer products to a predetermined position for electrical testing. The front side of each of the electrical testing bearing assemblies 32 is provided with the electrical testing assembly 34, and the electrical testing bearing assembly 32 moves the product forward to the electrical testing assembly 34 for testing, and then moves the product back after the electrical testing assembly 34 has completed the testing. Several of the pressing mechanisms 7 are fixedly arranged on one side of the electrical testing base 31 and correspond one-to-one with the electrical testing bearing assemblies 32, and the pressing mechanisms 7 press from top to bottom to relatively fix the product on the electrical testing bearing assemblies 32. The electrical testing transport assembly 33 is fixedly arranged on the other side of the electrical testing base 31 to avoid interference between the two. Specifically, the electrical test handling component 33 adsorbs the product and places it on the electrical test bearing component 32, and the electrical test bearing component 32 drives the product to move toward the electrical test component 34. When the electrical test bearing component 32 moves to the electrical test component 34, the pressing mechanism 7 presses the product tightly on the electrical test bearing component 32, and the electrical test component 34 performs electrical testing on the product. After the test is completed, the pressing mechanism 7 releases the product, and the electrical test bearing component 32 moves the product back to allow the electrical test handling component 33 to adsorb the product and send it out.

The bearing seat 322 is slidably connected to the bearing movable module 321, the rotating member 323 is fixedly arranged on the bearing seat 322, and the bearing seat 322 is fixed on the rotating member 323. In this way, the product can be placed on the detection platform 324, and the bearing seat 322 can slide relatively on the bearing movable module 321 to realize the transfer of the product. If it is found that the position of the product placed on the detection platform 324 is skewed, the angle of the product can be adjusted by the rotating member 323, so that the product fits the electrical test assembly 34.

[0037] An automatic electrical measuring machine provided in this embodiment, such as Figure 7 As shown, the pressing mechanism 7 includes a pressing base 71, a pressing movable rail 72, a pressing movable block 73, a connecting block 75, a pressing cylinder 74 and a pressing component 76.

The pressing component 76 is fixed on the connecting block 75, and the pressing cylinder 74 is fixed on the pressing base 71 and pushes the connecting block 75 to move. When it is necessary to press the product, the pressing cylinder 74 pushes the connecting block 75 downward, so that the pressing movable block 73 moves downward along the pressing movable track 72, and then the pressing component 76 presses on the product; when it is necessary to release the product, the connecting block 75 is pushed upward, so that the pressing movable block 73 moves upward along the pressing movable track 72, thereby releasing the product. The pressing mechanism 7 can be controlled quickly and conveniently, which is easy to control.

[0038] An automatic electrical measuring machine provided in this embodiment, such as Figure 8As shown, the material taking and discharging mechanism 2 includes a silo seat 21, a silo assembly 22, a material taking and discharging base 23, a first conveying module 25, a first tray conveying assembly 26, a second conveying module (not shown), a second tray conveying assembly 27 and a material taking and discharging transfer assembly 24.

The first tray conveying assembly 26 is slidably connected to the first conveying module 25, and the second tray conveying assembly 27 is slidably connected to the second conveying module. The material taking and discharging mechanism 2 at the front end is used for loading. When it is working, the first tray handling component 26 takes the full tray in the silo component 22 and places it on the material taking and discharging transfer component 24. The material taking and discharging transfer component 24 transfers the full tray to the other side of the material taking and discharging transfer component 24 for the loading mechanism 4 to absorb. When the material on the tray is taken and delivered, the second tray handling component 27 transfers the empty tray to the silo component 22 for collection and storage, and then the first tray handling component 26 takes and delivers the next full tray. In this way, the material taking and discharging can be completed fully automatically, and when the empty tray is collected and stored in a predetermined position, manual operation can be reduced, which can save labor costs and help reduce production costs. The material taking and discharging mechanism 2 at the rear end is used to collect materials and transfer empty trays to receive qualified products.

The mounting column is fixedly arranged at the four side corners of the material picking and placing transfer plate 242, the material picking and placing transfer bearing plate 243 is fixed on the mounting column, and a clearance space 245 is left between the material picking and placing transfer bearing plate 243 and the material picking and placing transfer plate 242, and a plurality of the material tray positioning members 244 are fixedly arranged in the clearance space 245. When the material picking and placing transfer assembly 24 transfers the material tray, the material tray positioning member 244 presses the material tray onto the material picking and placing transfer supporting plate 243 to ensure that the position of the material tray does not shift. When the material picking and placing is completed, the material tray positioning member 244 releases the material tray.

The tray positioning rod 2444 extends outward, so that the tray positioning block 2446 can press the edge of the tray, so as not to block the material being clamped. When the tray needs to be kept stationary, the tray positioning adjustment cylinder 2441 pushes the tray positioning adjustment block 2443 to move along the tray positioning adjustment track 2442, thereby driving the tray positioning block 2446 to move inward to press the tray.
