[0043] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will describe in detail the specific implementation manner, structure, features and effects of the present utility model with reference to the accompanying drawings and preferred embodiments.

[0044] As Figure 1-10 shown, this embodiment provides an electrical testing device for a main board, including,

[0045] At least one testing station 100, on which a first conveying mechanism and a second conveying mechanism are provided, and the conveying directions of the first conveying mechanism and the second conveying mechanism are opposite;

[0046] Return elevators, including at least a first return elevator 200 and a second return elevator 300, and are respectively located at both ends of the testing station 100, connecting the first conveying mechanism and the second conveying mechanism to form a complete conveying path;

[0047] Both the first return elevator 200 and the second return elevator 300 have a first position and a second position, the first position is connected to the first conveying mechanism, and the second position is connected to the second conveying mechanism.

[0048] The above is the basic solution of this embodiment.

[0049] Specifically referring to Figure 1 and Figure 2 shown, in this embodiment, three testing stations 100 are provided, and two return elevators are located at the outermost sides of the three testing stations 100; on these three stations, there are successively a main board 1 loading position, a module downloading position 140, a calibration position 150, a BLE programming position 160, an MCB programming position, and an FCT function testing position 180. The main board 1 is loaded at the main board 1 loading position, grabbed by the manipulator 120 onto the first conveying mechanism, and after passing through module downloading, calibration, BLE programming, MCU programming, and FCT function testing in sequence, it reaches the second return elevator 300 at the end, and enters the second conveying mechanism under the lifting action of the return elevator and is conveyed back to the first return elevator 200 at the beginning for unloading.

[0050] In this embodiment, the detection position structures and detection methods of each part are the same as those in the prior art, and will not be elaborated here.

[0051] In this embodiment, multiple test stations are set up and connected by two return elevators to form a complete automatic detection production line, which can automatically detect the main board 1, avoid damage to the main board caused by manual operation, and improve the test efficiency.

[0052] Specifically, the test station 100 includes a housing 110. The interior of the housing 110 is divided into two upper and lower transportation spaces by a carrier plate 111. The first conveying mechanism is located in the upper transportation space, and the second conveying mechanism is located in the lower transportation space.

[0053] The first conveying mechanism and the second conveying mechanism are on the same vertical plane.

[0054] Based on the above settings, the two conveying mechanisms are arranged in an upper and lower position, and the lifting mechanism is used to connect the two conveying mechanisms, making full use of the space inside the housing 110, with a reasonable layout and reducing the occupied area of the equipment.

[0055] In this embodiment, the specific implementation manners of the first conveying mechanism and the second conveying mechanism are as follows: both the first conveying mechanism and the second conveying mechanism include a positioning tooling 400 driven by a conveying component 600. A positioning post 410 matching the main board 1 is provided on the positioning tooling 400. The positioning post 410 positions and places the main board 1, and supports the main board 1 so that there is a gap between the main board 1 and the positioning tooling 400.

[0056] Specifically refer to Figure 3 and Figure 4 As shown, the positioning post 410 is fixed on the upper end surface of the positioning tooling 400, and the end extends above the positioning tooling 400. The main board 1 is provided with a positioning hole matching the positioning post 410. The main board 1 is placed on the positioning post 410 and is located above the positioning tooling 400 to avoid direct contact with the end surface of the positioning tooling 400 and cause wear.

[0057] Specifically, referring to Figure 5 As shown, the upper end of the positioning post 410 is set as an arc surface. When the positioning hole of the main board 1 cooperates with the positioning post 410, it can smoothly fit along the arc surface. Compared with the tip, it avoids scratching with the main board 1. At the same time, the upper diameter of the positioning post 410 is smaller than the lower diameter, so that the main board 1 can be supported on the positioning post 410.

[0058] In this embodiment, the specific setting of the positioning tooling 400 is as follows: the positioning tooling 400 includes an adjusting plate 430 and a bottom plate 420 arranged up and down, and the bottom plate 420 and the adjusting plate 430 are elastically supported and connected.

[0059] Specifically refer to Figure 5As shown, the adjusting plate 430 is located above the bottom plate 420 and is movably connected to the bottom plate 420 through guide posts 450. A spring 440 is sleeved on the guide posts 450, and the spring 440 is located between the adjusting plate 430 and the bottom plate 420.

[0060] The adjusting plate 430 is provided with a counterbore, and the upper end of the guide post 450 is limited in the counterbore, and the adjusting plate 430 can move along the guide post 450.

[0061] When the main board 1 is placed on the adjusting plate 430, the adjusting plate 430 moves downward under pressure. At this time, the spring 440 supports the adjusting plate 430.

[0062] During detection, the positioning tooling 400 can adaptively change the height position of the main board 1 according to the detection needs to meet the detection requirements.

[0063] In this embodiment, the first conveying mechanism further includes a detection seat 500, and the detection seat 500 includes a lifting plate 510 provided with detection needles 520.

[0064] The lifting plate 510 is located above the positioning tooling 400, and the main board 1 is located below the detection needles 520.

[0065] A lifting device 530 is provided on the side of the lifting plate 510.

[0066] Specifically referring to Figure 6 As shown, the lifting plate 510 is provided in a plate shape, and detection needles 520 are provided in the middle. Driven by the conveying assembly 600, the main board 1 reaches below the lifting plate 510, and the lifting device 530 drives the lifting plate 510 to move downward to align the detection needles 520 with the detection positions and detect the main board 1.

[0067] In this embodiment, the lifting device 530 is a conventional air cylinder that drives the detection seat 500 to lift.

[0068] In this embodiment, to ensure that each test position will not be interfered with when detecting the main board 1, a lifting stop block 700 is further provided on the first conveying mechanism, and the lifting stop block 700 is located on the side of the test station 100.

[0069] Specifically referring to Figure 7 and Figure 8 As shown, in this embodiment, a space for 6 detection units is provided at each detection position, that is, 6 main boards 1 can be detected simultaneously. Therefore, to ensure that during detection, the subsequent positioning tooling 400 cannot be continuously conveyed to this detection position.

[0070] In this embodiment, the lower end of the lifting block 700 is driven by a cylinder to lift and lower. When the six positioning tools 400 are transferred to the detection position, the lifting block 700 rises and stops at the end of the positioning tool 400, so that the subsequent positioning tool 400 cannot be transferred.

[0071] In this embodiment, the conveying assembly 600 includes a conveyor belt 610 tensioned and driven by a conveying wheel 630, and a support plate 620 is provided on the lower end surface of the upper conveyor belt 610;

[0072] The conveyor belt 610 is connected to a driving wheel 640 , and the driving wheel 640 is driven to rotate by a driving component 650 .

[0073] Specific reference Figure 9 As shown, two conveyor belts 610 are provided and arranged symmetrically. The positioning tool 400 is located between the two conveyor belts 610 and is supported and conveyed by the two conveyor belts 610. To ensure the supporting force of the conveyor belts 610, a support plate 620 is provided on the lower end surface of the conveyor belt 610. The conveyor belt 610 can move relative to the support plate 620 to convey the positioning tool 400. The support plate 620 supports the conveyor belt 610, thereby preventing the conveyor belt 610 from being deformed due to the pressure of the positioning tool 400, which would affect the conveying efficiency.

[0074] A driving wheel 640 is provided on the conveyor belt 610 , and the driving wheel 640 is driven by a driving component 650 to drive the conveyor belt 610 .

[0075] Preferably, in this embodiment, the driving wheel 640 is arranged in the middle of the conveyor belt 610.

[0076] Specific reference Figure 7 As shown, a transmission section is provided in the middle portion of each conveyor belt 610 , and the transmission section passes around the driving wheel 640 . When the driving wheel 640 rotates under the action of the driving component 650 , friction drive is generated on the transmission section, thereby moving the entire conveyor belt 610 .

[0077] Compared with transmitting at one end of the conveyor belt 610, in this embodiment, transmitting at the middle part of the conveyor belt 610 can balance the load received by the driving component 650. At the same time, the driving forces of the conveyor belts 610 on both sides are also symmetrical, ensuring stable transmission.

[0078] In this embodiment, the first return elevator 200 and the second return elevator 300 both include a transmission line 2 driven by a lifting assembly 3, and the transmission line 2 includes a belt driven by a rotating shaft;

[0079] The lifting assembly 3 drives the transmission line body 2 to move between the first position and the second position.

[0080] Specifically referring to Figure 10 As shown, the transmission line body 2 drives the positioning tooling 400 placed on the belt for horizontal transmission. At the same time, the lifting assembly 3 drives the transmission line body 2 to move up and down, thereby connecting the first conveying mechanism and the second conveying mechanism.

[0081] In this embodiment, the structures of the first return elevator 200 and the second return elevator 300 are the same as those of the return elevator in the prior art, and will not be elaborated here.

[0082] The driving device described in this embodiment can be a cylinder, an oil cylinder, an electric cylinder, etc.

[0083] The above are only the preferred embodiments of the present invention, and do not impose any formal restrictions on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications within the scope of the technical solution of the present invention to make equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
