[0021] The following further describes in detail the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 shown, an automatic testing device for a frequency converter PCBA includes a detection table 1 and a positioning component 3. A conveyor belt 2 is arranged in the middle of the upper end of the detection table 1. A support frame 4 is installed at the rear side of the upper end of the detection table 1, and a testing machine 5 is installed at the top of the support frame 4. An electric push rod 6 is installed at the lower end of the support frame 4, and a testing end 7 is installed at the output end of the electric push rod 6. A second hydraulic air rod 8 is installed on the right side surface of the support frame 4. The second hydraulic air rod 8 controls the expansion and contraction of a secondary material pushing plate 9 through expansion and contraction, so as to push the plates that are not tested simultaneously to the blanking slope 10 for blanking, for distinguishing the products. And a secondary material pushing plate 9 is installed at the output end of the second hydraulic air rod 8. A blanking slope 10 is installed on the right side of the front end of the detection table 1.

[0023] As Figure 2 shown, the positioning component 3 for testing the positioning of the board body is arranged on the front and rear sides of the upper end of the detection table 1, and the number of the positioning components 3 is set to two groups. The positioning component 3 includes an electric slide rail 301, an electric slider 302, a first hydraulic air rod 303 and a positioning frame 304. And an electric slider 302 is installed on the side of the electric slide rail 301. The electric slider 302 moves horizontally on the electric slide rail 301 for the horizontal movement of the positioning frame 304. A first hydraulic air rod 303 is installed on the surface of the electric slider 302. The first hydraulic air rod 303 controls the front and rear movement of the positioning frame 304 through expansion and contraction. And a positioning frame 304 is installed at the output end of the first hydraulic air rod 303. The two groups of positioning frames 304 can form a square structure to play a role in positioning on the outer side of the frequency converter PCBA board, so that it can be more accurately tested by the testing end 7, improving the testing accuracy. The shape of the positioning frame 304 is L-shaped, and the number of the positioning frames 304 is set to two groups.

[0024] As Figure 3 shown, a stacking prevention component 11 for protecting the stacking of the boards is arranged outside the conveyor belt 2 at the upper end of the detection table 1. The stacking prevention component 11 includes a protection frame 1101 and a baffle 1102. And a baffle 1102 is installed inside the protection frame 1101 through a threaded rod. The baffle 1102 can play a role in pushing the accidentally stacked boards to prevent the stacking of the boards from affecting the detection. The protection frame 1101 and the baffle 1102 are distributed in parallel. The shape of the protection frame 1101 is U-shaped. The protection frame 1101 is horizontally arranged above the conveyor belt 2. By rotating the threaded rod, the threaded rod rotates on the baffle 1102, and at this time, the position of the baffle 1102 is adjusted in the protection frame 1101.

[0025] In summary, for this automatic testing device for a frequency converter PCBA, first, according to Figure 1-Figure 3The structure shown in the figure moves the inverter PCBA sheet through the conveyor belt 2. According to the thickness of the sheet, the threaded rod is rotated, and the threaded rod rotates on the baffle 1102. At this time, the position of the baffle 1102 in the protection frame 1101 is adjusted. The baffle 1102 is adjusted to push the accidentally stacked sheets to avoid the stacking of the sheets affecting the detection. When the conveyor belt 2 moves the product to the bottom of the test end 7, the hydraulic gas rod 303 on the front side is extended to drive the positioning frame 304 to move backward, and the sheet on the conveyor belt 2 is moved from the right side. At the same time, the hydraulic gas rod 1 303 at the rear side is extended to drive the positioning frame 304 to move forward. At this time, the two groups of positioning frames 304 can form a mouth-shaped structure, which plays a positioning role on the outside of the inverter PCBA plate, so that it can be tested more accurately at the tested end 7, thereby improving the test accuracy. The qualified plates are unloaded from the right side. When the product is detected as unsuitable by the tested machine 5, the hydraulic gas rod 2 8 controls the extension and retraction of the secondary material push plate 9 through telescopic control, and pushes the plates that are not tested at the same time to the unloading slope 10 for unloading, so as to distinguish the materials.
