Description

Technical Field

[0001] This utility model relates to the field of magnetoelectric detonator technology, specifically to a magnetoelectric detonator ignition mechanism suitable for automated assembly. Background Technology

[0002] Magnetoelectric detonators are widely used in oil and gas well perforation and other fields due to their resistance to stray currents, static electricity, and high radio frequency currents, resulting in high safety and reliability. However, the ignition mechanism of traditional magnetoelectric detonators is complex and relies on manual assembly, leading to low production efficiency and safety hazards. Manual assembly is prone to human error, causing instability in the internal structure of the detonator, affecting product quality consistency, and consequently impacting detonator performance and reliability. With increasing safety requirements and the trend towards automated production, existing magnetoelectric detonator ignition mechanism designs can no longer meet the demands for efficient, safe, and consistent production, necessitating urgent improvement. Utility Model Content

The safety element is fixedly covered inside the upper part of the first colloid, and the first colloid has flat surfaces on both sides of the position where it covers the safety element.

[0006] The bottom end of the first colloid has a first step and a second step from top to bottom, and a rigid bridge head is installed at the bottom end of the first colloid. The rigid bridge head is integrated with the safety element through the first colloid.

[0007] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0008] The integrated flat design of the ignition mechanism and the integrated connection with the rigid bridge head greatly simplify the production and assembly process of traditional magnetic detonators. It can also be applied to automated detonator dipping and automated assembly lines, which can greatly improve the production efficiency of magnetic detonators, save labor costs, and reduce safety hazards.

[0009] Furthermore, the safety element is configured as a ring shape, and the top of the first colloid has a receiving cavity adapted to the safety element.

[0018] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0019] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0020] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0021] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0022] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0023] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0024] 1. This utility model adopts a hard plastic encapsulation integrated structure process. The encapsulated safety element part is designed with a flat structure, which facilitates clamping and positioning in automated assembly, reduces production assembly steps, and improves production safety.

[0025] 2. The first step of this utility model can realize the uprighting of the mechanism when it is assembled in the detonator, and at the same time facilitate the positioning of the ignition distance inside the detonator. The second step is used to fix the heat shrink tubing during subsequent assembly process to prevent the heat shrink tubing from falling off.

[0026] 3. The second colloid of this utility model covers the outer edge of the first colloid above the first step, and is used to buffer the clamping pressure. When clamped with the tube shell, it can withstand a static tensile force of 39.2N. Attached Figure Description

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0032] Example 1:

[0033] Based on the concept of this application, combined with Figures 1 to 2 This invention describes an embodiment of a magnetoelectric detonator ignition mechanism suitable for automated assembly, used for perforation ignition in oil and gas well cables. Specifically, this magnetoelectric detonator ignition mechanism is constructed as an integral structure, comprising three components: a first colloid 1, a safety element 2, and a rigid bridge head 4. In this invention, the rigid bridge head 4 directly dips into the propellant tip and snaps into the base detonator to form a magnetoelectric detonator. This mechanism is compatible with automated propellant dipping machines and automated detonator assembly machinery, offering simple operation, high product consistency, improved product reliability, reduced labor costs, and lower safety risks.

[0034] Combination Figures 1-2 As shown, the present invention provides a magnetoelectric detonator ignition mechanism suitable for automated assembly, including a first colloid 1 and a safety element 2. The safety element 2 is fixedly covered inside the upper part of the first colloid 1, and flat surfaces 5 are provided on both sides of the position where the first colloid 1 covers the safety element 2.

[0035] The bottom end of the first colloid 1 has a first step 1-1 and a second step 1-2 sequentially formed from top to bottom, and a rigid bridge head 4 is installed at the bottom end of the first colloid 1. The rigid bridge head 4 is integrated with the safety element 2 through the first colloid 1.

[0036] In this embodiment, the safety element 2 is fixed in the first colloid 1 using a high-temperature pressing process. The safety element 2 is ring-shaped, and the top of the first colloid 1 has a receiving cavity adapted to the safety element 2. The high-temperature pressing process embeds the safety element 2 into the first colloid 1, which significantly improves structural stability and ensures that the safety element 2 remains firmly in place during detonator assembly and ignition, preventing loosening or detachment. Simultaneously, the planar design 5 of the first colloid 1, combined with the high-temperature pressing, allows for precise positioning of the safety element 2, facilitating automated assembly. Furthermore, this process, combined with the flexibility of the first colloid 1, enhances the detonator's impact resistance, ensuring the safety element 2 remains stable during blasting and improving the overall safety and reliability of the detonator.

[0037] Regarding the technical solution of this embodiment, the outer edge of the first colloid 1 above the first step 1-1 is covered with a second colloid 3. The elasticity of the second colloid 3 can buffer the pressure during the snap-fit, preventing the first colloid 1 from directly contacting the tube shell and causing wear or stress concentration, thus protecting the tube shell. Furthermore, the second colloid 3 fits tightly with the tube shell, making the mechanism highly stable after snap-fit ​​and able to withstand at least 39.2N static tensile force, ensuring the stability of the mechanism inside the detonator. At the same time, in automated assembly, the elastic buffering effect of the second colloid 3 makes it easier for the mechanism to be embedded into the tube shell, reducing manual intervention and improving assembly efficiency.

[0038] Regarding the technical solution of this embodiment, the hardness of the first colloid 1 is greater than that of the second colloid 3, and the material of the first colloid 1 is set as heat-resistant nylon.

[0039] Regarding the technical solution of this embodiment, the plane of the first colloid 1 covering the safety element 2 is set as a symmetrical double-plane structure, which facilitates stable and precise assembly by using external assembly equipment, such as a robotic arm gripper, to hold both sides of the first colloid.

[0040] In the technical solution of this embodiment, the material of the second colloid 3 is set as heat-resistant silicone, and the coating thickness of the second colloid 3 is 0.6mm.

[0041] Regarding the technical solution of this embodiment, the bottom end of the first colloid 1 extends to form a wrapping portion covering the end of the rigid bridge head 4. The rigid joint is coaxially arranged with the first colloid 1. The wrapping portion enhances the fixation of the rigid bridge head 4, utilizes the flexibility of the first colloid 1 to buffer impacts and vibrations, protects the bridge head from stress concentration damage, and improves connection firmness and impact resistance. Secondly, the coaxial arrangement ensures structural symmetry and uniform force distribution, avoids skewing and excessive local stress, improves assembly accuracy and reliability, reduces processing errors, and optimizes the assembly process. Furthermore, this design facilitates subsequent heat shrink tubing fixation, enhancing the overall structural stability. Finally, the wrapping portion works in conjunction with other functions of the first colloid 1, such as straightening and positioning, to optimize the overall performance of the mechanism, achieve functional integration, and improve product consistency and reliability.

[0042] Regarding the technical solution of this embodiment, the first step 1-1 is set as an annular boss with a rectangular cross-section, and the height of the annular boss is determined according to the inner diameter of the matching detonator shell. The first step 1-1 can ensure that the first colloid 1 remains upright when assembled inside the detonator, preventing skewing after the detonator is snapped in place, thereby improving assembly accuracy and improving the reliability of the propellant head ignition. Secondly, the design of the first step 1-1 and the plane 5 of the first colloid 1 are designed to provide a positioning reference for the automated assembly fixture, and also facilitate the positioning of the ignition distance inside the detonator, further improving the accuracy of assembly.

[0043] Regarding the technical solution of this embodiment, the second step 1-2 includes a plurality of serrated grooves formed on the bottom sidewall of the first colloid 1. The setting of the second step 1-2 can enhance the fixing effect of the heat shrink tubing. The serrated shape increases the friction and provides an "engaging" effect, preventing the heat shrink tubing from sliding or falling off when under force, ensuring the reliability of the connection. It can also optimize the mechanical properties of the first colloid 1. The serrated shape can disperse the impact force and stress generated during assembly and use, reduce local stress concentration, thereby extending the service life of the mechanism and improving the stability and durability of the overall structure.

[0044] Specifically, in use, the rigid bridge head of the mechanism directly dips the explosive tip into the four parts and snaps it into the base detonator to form a magnetoelectric detonator. The mechanism is compatible with automated explosive dipping machines and automated detonator assembly machines. It is easy to operate, has a high degree of product consistency, which helps to improve product reliability, while saving labor costs and reducing safety risks.

[0045] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the ignition mechanism for a magnetoelectric detonator suitable for automated assembly provided by this utility model.

[0046] A magnetoelectric detonator ignition mechanism suitable for automated assembly includes a first colloid 1 and a safety element 2. The safety element 2 is fixedly covered inside the upper part of the first colloid 1, and flat surfaces 5 are provided on both sides of the position where the first colloid 1 covers the safety element 2.

[0047] The bottom end of the first colloid 1 has a first step 1-1 and a second step 1-2 sequentially formed from top to bottom, and a rigid bridge head 4 is installed at the bottom end of the first colloid 1. The rigid bridge head 4 is integrated with the safety element 2 through the first colloid 1.

[0048] The working principle and usage process of this utility model: The rigid bridge head of the mechanism directly dips the explosive head into the four parts and snaps it into the base detonator to form a magnetoelectric detonator. This mechanism can be adapted to automated explosive dipping machines and automated detonator assembly machines. It is simple to operate, has a high degree of product consistency, which helps to improve product reliability, while saving labor costs and reducing safety risks.
