Description

Technical Field

[0001] This utility model relates to the field of electronic detonator manufacturing technology, specifically to a fixture for testing electronic detonators. Background Technology

[0002] In the production of electronic detonators in the civil explosives industry, electronic detonators currently mainly consist of three parts: the detonator body, the lead wire, and the wire clamp. The lead wire is coiled into a bundle, with one end welded and fixed to the joint of the detonator body, and the other end installed in the wire clamp. In order to achieve automated production of electronic detonators, it is necessary to use fixtures to fix the electronic detonators.

[0003] Chinese Utility Model Patent; Publication No.: CN 213932240 U, ​​a fixture for producing electronic detonators, comprising: a base plate, with a first side plate and a second side plate respectively on both sides of the base plate, defining an accommodating space for accommodating lead wires between the first side plate, the second side plate, and the base plate; a first positioning plate disposed on the first side plate, having a plurality of first positioning grooves for positioning wire clips; a second positioning plate disposed on the second side plate, having a plurality of second positioning grooves for positioning the detonator body; a plurality of positioning post groups disposed on the base plate, located within the accommodating space, for winding lead wires; and a positioning and fixing structure disposed on the base plate for positioning and fixing the base plate. This fixture for producing electronic detonators can accurately and orderly position electronic detonators, avoiding messy lead wires and inaccurate positioning of the detonator body and wire clips, which would affect the realization of production assembly, electrical testing, and packaging processes.

[0004] Although the above equipment can clamp the detonator leads, the two ends of the coiled detonator leads are of the same length. The detonator leads are then placed on the base plate, and the two ends of the detonator leads are respectively mounted on the first positioning plate and the second positioning plate. However, there is a height difference between the detonator leads and the first and second positioning plates. If the detonator leads are placed on the positioning post assembly during the coiling process, the extended lines at both ends of the detonator leads are too short, resulting in an unsuitable welding height at both ends and a height difference during welding. If the extended lines at both ends of the detonator leads are too long, an arched shape will appear at both ends of the leads, thus affecting subsequent welding. Utility Model Content

[0005] In view of this, the present invention provides a fixture for testing electronic detonators. The present invention can compensate for the height difference between the lead wire and the positioning plate one and positioning plate two, so that the two ends of the lead wire can be installed according to the length of the two ends of the lead wire that need to be coiled, thus avoiding the height difference during welding.

[0006] To solve the above-mentioned technical problems, this utility model provides a fixture for testing electronic detonators, including a wiring box. Positioning plate one and positioning plate two are respectively provided at both ends of the wiring box. Positioning plate one has a fixing block one with several positioning wire clip slots. Positioning plate two has a fixing block two with several detonator body positioning slots. A lifting assembly is provided inside the wiring box. The lifting assembly includes several guide slots vertically arranged on both sides of the inner wall of the wiring box, and a lifting plate slidably arranged between the guide slots. Specifically, when personnel place the coiled lead wires one by one into the wiring box, and then install them into the positioning wire clip slots according to the length of both ends of the coiled lead wires, the lifting plate is driven to move upwards on the wiring box, thereby compensating for the height difference between the lead wires and positioning plates one and two. This allows for installation of the two ends of the lead wires according to their required length, avoiding height differences during welding.

[0007] The lifting assembly also includes a slide groove set inside the wiring box. Two sliding blocks are slidably arranged inside the slide groove. A hinge seat 1 is set on the top of the two sliding blocks. Two hinge seats 2 are set at the bottom center of the lifting plate. A hinge rod is set between the hinge seat 1 and the hinge seat 2. That is, the hinge rod is used to enhance the connection between the hinge seat 1 and the hinge seat 2, and at the same time, the hinge rod can lift the lifting plate.

[0008] The lifting assembly also includes a bidirectional lead screw rotatably disposed in the slide groove, which passes through the interior of the two sliding blocks; that is, the bidirectional lead screw can drive the two sliding blocks to move closer to each other or further apart.

[0009] The lifting assembly also includes a drive button located on the side of the wiring box, the side of which is connected to one end of the bidirectional lead screw; that is, the drive button provides actuation to the bidirectional lead screw.

[0010] The upper surface of the positioning plate one is provided with a straight notch groove one, which is located at the side end of the fixing strip one. The positioning plate two is provided with a fixing strip two, which is provided with several lead wire positioning grooves. The side end of the fixing strip two is provided with a straight notch groove two. That is, the end of the lead wire connected to the detonator body passes through the top of the straight notch groove two and connects to the detonator on the positioning groove block of the detonator body, thereby facilitating subsequent welding.

[0011] Handles are provided on both sides of the junction box; making it easy for personnel to lift the junction box.

[0012] The outer surface of the handle is fitted with a rubber pad, which enhances the comfort of the handle.

[0013] Several positioning post groups are set on both sides of the lifting plate; thus facilitating the initial positioning of the coiled baseboard.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By rotating the drive button, the double-acting screw can be driven to rotate, causing the two sliding blocks to move closer or further apart. This indirectly moves the hinge seat, allowing the hinge rod to control the raising and lowering of the lifting plate. This compensates for the height difference between the lead wire and the positioning plates 1 and 2, allowing the lead wire ends to be installed according to the required length, thus avoiding height differences during welding.

[0015] 2. Several positioning post groups are set on both sides of the lifting plate to place and position the coiled detonator. Attached Figure Description
