[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0030] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0031] Refer to Figures 1-5, A fixture for LCM electrical testing, comprising an installation and placement base 1, an LCM workpiece 7, and a belt conveyor body 11. The belt conveyor body 11 is installed and connected to the upper groove of the installation and placement base 1. The LCM workpiece 7 is placed on the conveyor belt of the belt conveyor body 11. Thus, the belt conveyor body 11 can drive the LCM workpiece 7 to be conveyed and detected on the installation and placement base 1. A rotating feeding mechanism 6 is installed on the installation and placement base 1 outside the belt conveyor body 11. The rotating feeding mechanism 6 effectively blocks the conveyance of the LCM workpiece 7. When the rotating feeding mechanism 6 rotates, it can feed and convey the LCM workpiece 7. An adjustable support arm plate 2 is installed in the middle at the rear side of the upper end of the installation and placement base 1. A storage battery 3 is installed at the upper end of the adjustable support arm plate 2, so that it can be used for corresponding power supply. A detection display screen 4 is installed at the front side of the upper end of the adjustable support arm plate 2, and the detection information is displayed on the detection display screen 4 for easy viewing by personnel. A mobile detection mechanism 5 is installed at the lower side of the upper end of the adjustable support arm plate 2. Thus, the mobile detection mechanism 5 can perform electrical testing on the LCM workpiece 7 below. The storage battery 3, the detection display screen 4, the mobile detection mechanism 5, the rotating feeding mechanism 6, and the belt conveyor body 11 are connected to the control switch of the installation and placement base 1 through connecting wires, so that they can be controlled correspondingly;

[0032] The rotating feeding mechanism 6 includes a rotating motor 61, a concave rotating plate 62, an internal rubber plate 63, and a positioning sleeve seat 64. The internal rubber plate 63 is installed on the inner side of the lower end of the concave rotating plate 62. The positioning sleeve seats 64 are installed at both ends of the concave rotating plate 62. The two positioning sleeve seats 64 are symmetrically installed and connected to the installation and placement base 1 and are located outside the belt conveyor body 11. Thus, the concave rotating plate 62 and the internal rubber plate 63 are located above the belt conveyor body 11 to play a blocking role. The rotating motor 61 is installed on the left end of the concave rotating plate 62 on the positioning sleeve seat 64. The rotating motor 61 is connected to the concave rotating plate 62 through a coupling. Thus, the rotating motor 61 can drive the concave rotating plate 62 to rotate for feeding and detection. The concave rotating plate 62 can effectively block the outside of the LCM workpiece 7 through the internal rubber plate 63. Thus, when it rotates to a conveying gap with the thickness of one LCM workpiece 7, only one LCM workpiece 7 can be conveyed for electrical testing, avoiding omissions caused by superimposed detection.

[0033] Refer to Figure 1 , Figure 3 and Figure 4, in a preferred embodiment, the adjustable support arm plate 2 includes a triangular reinforcing block 21, a top horizontal plate 22, a bottom socket plate 23, an internal movable plate 24, an assembly long screw 25 and a locking bolt 26. A triangular reinforcing block 21 is fixedly connected to the front side of the lower end of the bottom socket plate 23. The bottom socket plate 23 is fixedly connected to the installation and placement base 1 through the triangular reinforcing block 21, so that the bottom socket plate 23 and the triangular reinforcing block 21 can be installed and fixed. The inner side of the upper end of the bottom socket plate 23 is sleeved with an internal movable plate 24, and a locking bolt 26 is installed at the connection between the bottom socket plate 23 and the internal movable plate 24. Thus, when the locking bolt 26 is loose, the internal movable plate 24 can be positioned and moved in the bottom socket plate 23. The upper end of the internal movable plate 24 is installed with a top horizontal plate 22, so that the internal movable plate 24 can drive the top horizontal plate 22 to change the height position. An assembly long screw 25 is installed on the inner side of the front end of the top horizontal plate 22. The top horizontal plate 22 is connected to the detection display screen 4 through the assembly long screw 25, so that the detection display screen 4 can be installed and placed. The lower end of the top horizontal plate 22 is connected to the mobile detection mechanism 5, so that the mobile detection mechanism 5 is suspended for electrical measurement;

[0034] The bottom socket plate 23 and the internal movable plate 24 are connected by sleeving, and the lower end of the internal movable plate 24 is sleeved inside the bottom socket plate 23, so that the internal movable plate 24 can be positioned and moved in the bottom socket plate 23;

[0035] The internal movable plate 24 and the top horizontal plate 22 are connected by screws, which is convenient for installation and disassembly, and a rubber pad is placed at the connection, making it more tightly fixed when fixed.

[0036] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5, in a preferred embodiment, the movement detection mechanism 5 includes a detection connecting plate 51, a lead screw body 52, a lead screw motor 53, a lead screw slider 54, and an electric telescopic cylinder 55. The output end of the lead screw motor 53 is connected to the internal lead screw of the lead screw body 52 through a coupling. A lead screw slider 54 is installed on the periphery of the internal lead screw of the lead screw body 52. Thus, when the output end of the lead screw motor 53 drives the coupling to rotate forward and backward, it can drive the internal lead screw of the lead screw body 52 to rotate forward and backward. As a result, the forward and backward rotation of the internal lead screw of the lead screw body 52 enables the lead screw slider 54 to move back and forth. The lower end of the lead screw slider 54 is installed and connected to the electric telescopic cylinder 55, so that the position of the electric telescopic cylinder 55 can be changed. The lower end of the telescopic rod of the electric telescopic cylinder 55 is installed with a detection connecting plate 51, so that the detection position of the detection connecting plate 51 can be changed. When the telescopic rod of the electric telescopic cylinder 55 expands and contracts, it can drive the detection connecting plate 51 to lift, so that the height position can be changed by lifting for detection. The detection connecting plate 51 is electrically connected to the detection display screen 4 through a connecting wire, so that the detection data can be displayed on the detection display screen 4, which is convenient for personnel to view. The lead screw body 52 is installed and connected to the top cross plate 22, so that it can be correspondingly installed and placed;

[0037] The lead screw slider 54 and the electric telescopic cylinder 55 are connected by screws, so that they can be installed and fixed, and a rubber pad is placed at the connection, making it more tightly and firmly installed.

[0038] Referring to Figure 1 and Figure 2 , in a preferred embodiment, a placement marking line is provided in the middle of the output belt of the belt conveyor body 11, so as to facilitate personnel to determine the placement position.

[0039] Working principle: When in use, personnel place the LCM workpiece 7 on the belt conveyor body 11. Through the rotating material discharging mechanism 6, the discharging electro - measurement can be rotationally controlled to avoid missing detection. After the LCM workpiece 7 is conveyed to the detection position by the belt conveyor body 11, the movable detection mechanism 5 inside the upper inner side of the adjustable support arm plate 2 can perform electro - measurement on the LCM workpiece 7 below. The detection information is displayed on the detection display screen 4 for personnel to view, and the storage battery 3 can be used for power supply.

[0040] The above - mentioned is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present utility model and its inventive concept should be covered within the protection scope of the present utility model.
