Description

Technical Field

[0001] This utility model relates to the field of test fixture technology, and in particular to a fuse test fixture. Background Technology

[0002] A fuse is a protective device that breaks the circuit by melting its fusible element when the current exceeds a specified value.

[0003] The existing technology patent (patent number: 202422709915.1, patent name: a fuse test fixture) uses a structure with a dual-axis motor, worm gear, worm and reciprocating lead screw to realize the function of synchronously driving the first electrode block on both sides to move to the second electrode block, so as to achieve the effect of no manual control.

[0004] However, the above-mentioned technical patent has the following drawbacks: when testing the fuse, the tester still needs to manually install the fuse, and after the test is completed, the tester needs to remove the fuse. The degree of automation is low, resulting in insufficient testing efficiency for the fuse. Therefore, a fuse testing fixture is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-5 A fuse testing fixture includes a workbench 2 and a conveying and feeding seat 1 rotatably mounted on the top of the workbench 2. The top of the conveying and feeding seat 1 is provided with a circumferentially distributed placement groove 101 for placing fuses, and the placement groove 101 is perfectly matched with the fuses.

[0025] The bottom end of the workbench 2 is provided with a drive mechanism for driving the conveyor loading seat 1 to rotate. Further, the drive mechanism includes a rotating shaft fixedly connected to the bottom end of the conveyor loading seat 1. The rotating shaft extends downward and passes through the workbench 2. The bottom end of the rotating shaft is fixedly connected with a reduction gear 10. A drive motor 11 is provided below the workbench 2. The output end of the drive motor 11 is fixedly connected with a drive gear 9 that meshes with the reduction gear 10.

[0026] It should be noted that: the drive motor 11 drives the drive gear 9 at its output end to rotate intermittently, which in turn drives the reduction gear 10 meshing with it to rotate intermittently. The reduction gear 10 drives the conveyor loading seat 1 to rotate intermittently through the rotating shaft. Each rotation angle is 1 / N degrees, where N is the number of conveying slots.

[0027] A feeding pipe 3 is provided above one of the placement slots 101 at the top of the workbench 2. Pin clamping assemblies are provided on both sides of one of the placement slots 101 at the top of the workbench 2. Further, the pin clamping assembly includes a fixed electrode block 7 installed at the top of the workbench 2. A movable electrode block 5 is provided above the fixed electrode block 7. A clamping groove for clamping pins is opened at the bottom of the movable electrode block 5 (when the movable electrode block 5 and the fixed electrode block 7 clamp the pins, the pins are located inside the clamping groove). A magnetic repulsion block 4 is provided at the top of the movable electrode block 5. Further, a groove is opened below the fixed electrode block 7 at the top of the workbench 2. An electromagnet 12 is installed inside the groove.

[0028] It should be noted that a controller (the controller is existing technology and is not shown in the figure) is installed on the workbench 2. The controller is used to control the intermittent rotation of the drive motor 11 and to control the opening and closing of the electromagnet 12. Before the controller controls the drive motor 11 to work, the controller will first control the electromagnet 12 to work. The magnetic repulsion between the electromagnet 12 and the magnetic repulsion block 4 will cause the movable electrode block 5 to move upward, so that the pins at both ends of the fuse can move to the fixed electrode block 7.

[0029] Furthermore, a guide groove 701 is provided at the top of the fixed electrode block 7, and a guide rod 13 that is slidably connected to the bottom of the movable electrode block 5 is fixedly connected to the guide groove 701. A terminal connection component 6 is installed on the side wall of the fixed electrode block 7.

[0030] It should be noted that the guide rod 13 and the guide groove 701 work together to guide the upward movement of the anode electrode block, while preventing the anode electrode block from separating from the cathode electrode block.

[0031] Furthermore, an arc-shaped actuating piece 8 is fixedly connected to the top of the workbench 2 near the placement slot 101. When the fuse approaches the arc-shaped actuating piece 8, the arc-shaped actuating piece 8 will push the pin at one end of the fuse, thereby pushing the fuse to move, so that the intact fuse can be removed from the placement slot 101. For the fuse that has blown, since the middle part of the fuse has melted and is no longer connected, the complete fuse is divided into two parts, and there is a gap between the two parts. The arc-shaped actuating piece 8 can only push one part of the fuse to move, so it cannot make the blown fuse leave the placement slot 101. The tester needs to remove it manually.

[0032] When using this utility model, the fuses are placed one by one in the feeding tube 3. The fuses are stacked one by one in the feeding tube 3. At the same time, the terminal connection component 6 is connected to the external circuit.

[0033] The controller controls the operation of the drive motor 11, which drives the drive gear 9 at its output end to rotate intermittently, thereby driving the reduction gear 10 meshing with it to rotate intermittently. The reduction gear 10 drives the conveyor loading seat 1 to rotate intermittently through the rotating shaft. When the placement groove 101 rotates to the discharge pipe 3, the fuse at the bottom of the discharge pipe 3 will fall into the placement groove 101. When the conveyor loading seat 1 rotates again, the top of the conveyor loading seat 1 contacts the bottom of the discharge pipe 3 to prevent the fuse from falling.

[0034] When the conveyor 1 carrying the fuse approaches the cathode electrode block, the controller will control the electromagnet 12 to work. Using the magnetic repulsion between the electromagnet 12 and the magnetic repulsion block 4, the movable electrode block 5 moves upward, so that the pins at both ends of the fuse can move to the fixed electrode block 7. When the fuse stops at the cathode electrode block, the controller turns off the electromagnet 12. At this time, the anode electrode block moves downward under its own gravity, and works with the cathode electrode block to achieve the function of clamping the pins.

[0035] At this time, the external circuit supplies power to the fixed electrode block 7 through the terminal connection component 6, and then supplies power to the fuse to realize the test function of the fuse, thereby realizing the automatic feeding function of the fuse, improving the automation level of the test, and thus improving the test efficiency.

[0036] After the test, the controller controls the electromagnet 12 to work again, causing the movable electrode block 5 to move upward. Then, it controls the conveyor feeding seat 1 to rotate. When the tested fuse approaches the arc-shaped actuating piece 8, the arc-shaped actuating piece 8 will push the pin at one end of the fuse, thereby pushing the fuse to move, so that the intact fuse can be removed from the placement slot 101 (a recycling box can be placed at the placement slot 101 at the arc-shaped actuating piece 8 before the test, so that the intact fuse can be recycled). For the blown fuse, since the middle of the fuse has melted and is no longer connected, the complete fuse is divided into two parts, and there is a gap between the two parts. The arc-shaped actuating piece 8 can only push one part of the fuse to move, so it cannot make the blown fuse remove from the placement slot 101. The tester needs to remove it manually.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
