Description

Technical Field

[0001] This utility model relates to the field of electronic detonator lead wire testing technology, and more specifically, to an electronic detonator lead wire testing mechanism. Background Technology

[0002] In the detonator production process, the three core stages of electronic ignition element manufacturing, electronic module welding, and finished electronic detonator inspection inevitably produce defective leads. These defective leads are not discarded directly, but need to be reworked and put back into production. Before rework, they must pass a continuity test to ensure their performance meets the standards. Only leads that pass the test can be used again in production. This is a crucial preliminary step to ensure the quality and safety of subsequent detonator products.

[0003] In existing technologies, a resistance meter is commonly used to test the continuity of the lead wire. This traditional testing method has significant drawbacks: firstly, the operation requires two workers to cooperate in simultaneously testing the lead wire clip and the injection molding end, which not only increases labor costs but also makes the testing process more cumbersome; secondly, due to the limitations of manual operation efficiency and the resistance meter testing method, the manual efficiency of lead wire continuity testing can only reach 300 detonations / hour. Such efficiency is difficult to meet the large-scale, high-efficiency production needs of detonator production lines, seriously restricting the overall production progress and failing to meet the requirements of modern production for efficient testing. Therefore, this utility model provides an electronic detonator lead wire testing mechanism to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an electronic detonator lead wire testing mechanism, which has the advantages of reducing labor costs and improving testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic detonator lead wire detection mechanism, comprising: a main structure, the main structure including a power supply base, a detection device, an indicator light, an audible and visual alarm, an injection-molded end contact point, and an electric push rod; The fixed structure includes a wire clip slot, a wire clip end contact point, and a photoelectric sensor. The wire clip slot is fixedly connected to one side of the upper surface of the power supply base.

[0006] As a preferred embodiment of this utility model, an anti-slip pad is fixedly connected to the lower surface of the power supply base, and the anti-slip pad is made of rubber, with multiple anti-slip grooves formed inside the lower surface of the anti-slip pad.

[0007] As a preferred embodiment of this utility model, the detection device is fixedly connected to one end of the upper surface of the power supply base, and the indicator light and the audible and visual alarm are both installed on the upper surface of the detection device. The indicator light and the audible and visual alarm are electrically connected to the detection device.

[0008] As a preferred embodiment of this utility model, the injection end contact point is installed at the other end of the upper surface of the power supply base, the injection end contact point is electrically connected to the detection device, a support frame is fixedly connected to the upper surface of the power supply base, the electric push rod is fixedly connected to the upper end of the support frame, a buffer pad is fixedly connected to the lower end of the push rod inside the electric push rod, and the electric push rod is electrically connected to the detection device.

[0009] As a preferred embodiment of this utility model, the contact point of the wire card end is installed on the lower surface inside the wire card slot, the contact point of the wire card end is electrically connected to the detection device, positioning guide bevels are provided on both sides of the upper surface of the wire card slot, and a wire groove is provided inside the surface of one end of the wire card slot.

[0010] As a preferred technical solution of this utility model, anti-slip protrusions are fixedly connected to both sides of the inner surface of the contact point of the wire clip, and the anti-slip protrusions are made of silicone.

[0011] In a preferred embodiment of this invention, the photoelectric sensor is installed inside one side surface of the card slot, and the photoelectric sensor is electrically connected to the electric push rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a cable slot to limit the movement of the lead wire clip. After the lead wire clip enters the slot, the photoelectric sensor sends a signal to the electric push rod. The push rod inside the electric push rod then moves the buffer pad downwards. At this time, the buffer pad applies a certain pressure to the lead wire clip, ensuring good contact between the contacts inside the lead wire clip and the contacts at the end of the clip. This design allows the device to fix the lead wire clip during the detection process, reducing the lead wire continuity detection work from two people to one person.

[0013] 2. This utility model, by connecting the injection-molded end of the lead wire to the injection-molded end contact point, ensures that a qualified lead wire, with copper wire inside, forms a complete circuit through the injection-molded end contact point and the wire clip contact point, connecting to the indicator light. This causes the indicator light to light up green and triggers an audible and visual alarm to indicate that the test is qualified. Conversely, a defective lead wire cannot form a closed circuit, causing the indicator light to light up red and triggering an audible and visual alarm to indicate that the test is unqualified. This design allows operators to observe the test results more intuitively, increasing the manual efficiency of lead wire continuity testing from 300 tests / hour to 800 tests / hour, a 160% increase in efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides an electronic detonator lead wire testing mechanism, including... The main structure 1 includes a power supply base 11, a detection device 13, an indicator light 14, an audible and visual alarm 15, an injection end contact point 16, and an electric push rod 18. The fixing structure 2 includes a wire card slot 21, a wire card end contact point 22 and a photoelectric sensor 26. The wire card slot 21 is fixedly connected to one side of the upper surface of the power supply base 11.

[0018] The lower surface of the power supply base 11 is fixedly connected to an anti-slip pad 12, which is made of rubber and has multiple anti-slip grooves inside the lower surface of the anti-slip pad 12.

[0019] The anti-slip pad 12 effectively improves the overall stability of the device during use, reducing the possibility of movement. The anti-slip groove further enhances the anti-slip effect. The power supply base 11 contains a battery that provides power to the entire device.

[0020] The detection device 13 is fixedly connected to one end of the upper surface of the power supply base 11. The indicator light 14 and the audible and visual alarm 15 are both installed on the upper surface of the detection device 13. The indicator light 14 and the audible and visual alarm 15 are electrically connected to the detection device 13.

[0021] The continuity between the injection end contact point 16 and the wire clamp end contact point 22 can be detected by the detection device 13. The detection device 13 has a resistance range of 0.1-10Ω, a response time of ≤0.5s, and is compatible with a power supply voltage of 12V DC. When a complete circuit is formed between the injection end contact point 16 and the wire clamp end contact point 22, the indicator light 14 will light up green and the audible and visual alarm 15 will provide a voice prompt indicating that the test is qualified. When a closed circuit cannot be formed between the injection end contact point 16 and the wire clamp end contact point 22, the indicator light 14 will light up red, and the audible and visual alarm 15 will sound an alarm and indicate that the test is unqualified.

[0022] The injection end contact point 16 is installed at the other end of the upper surface of the power supply base 11. The injection end contact point 16 is electrically connected to the detection device 13. A support frame 17 is fixedly connected to the upper surface of the power supply base 11. The electric push rod 18 is fixedly connected to the upper end of the support frame 17. A buffer pad 19 is fixedly connected to the lower end of the push rod inside the electric push rod 18. The electric push rod 18 is electrically connected to the detection device 13.

[0023] The buffer pad 19 can be moved by activating the electric push rod 18. The electric push rod 18 has a stroke of 20-30mm, a thrust of 50-100N, and a telescopic speed of 10mm / s. The position of the buffer pad 19 corresponds to the position inside the cable clip slot 21. Therefore, when the buffer pad 19 moves, it can apply pressure to the lead cable clip inside the cable clip slot 21, thereby preventing the lead cable clip from shifting inside the cable clip slot 21. The buffer pad 19 is made of silicone rubber with a Shore hardness of 50-60. This material has both elasticity and wear resistance, which can not only prevent damage to the lead cable clip, but also provide stable fixing force.

[0024] The wire card end contact point 22 is installed on the lower surface inside the wire card slot 21. The wire card end contact point 22 is electrically connected to the detection device 13. Positioning guide bevels 23 are provided on both sides of the upper surface of the wire card slot 21. A wire groove 24 is provided inside one end surface of the wire card slot 21.

[0025] With the opening of two sets of positioning guide angled openings 23, when the operator inserts the lead wire clip, it can guide the lead wire clip to quickly align with the center position inside the clip slot 21, eliminating the need for repeated position adjustments, reducing positioning time, and improving the smoothness of operation.

[0026] Among them, anti-slip protrusions 25 are fixedly connected to both sides of the inner surface of the contact point 22 of the line card end, and the anti-slip protrusions 25 are made of silicone.

[0027] Because of the elasticity of the silicone material, when the lead wire clip is inserted into the clip slot 21, it can fit tightly against the outer wall of the clip through the slight deformation of the anti-slip protrusions 25, thus preventing the clip from shifting during the testing process. At the same time, the friction of the silicone can prevent the clip from slipping off accidentally, and does not affect the normal insertion and removal of the clip.

[0028] The photoelectric sensor 26 is installed inside one side surface of the card slot 21, and the photoelectric sensor 26 is electrically connected to the electric push rod 18.

[0029] The photoelectric sensor 26 can detect the inside of the cable card slot 21. When the cable card is inserted into the cable card slot 21, it will block the light emitted by the photoelectric sensor 26. At this time, the photoelectric sensor 26 can send a signal to the electric push rod 18, causing the push rod inside to move the buffer pad 19 downward. After the detection is completed, the detection device 13 will send a signal to the electric push rod 18, causing the push rod inside to move upward.

[0030] The working principle and usage process of this utility model are as follows: First, the operator inserts the lead wire clip into the clip slot 21. Then, after the photoelectric sensor 26 detects the insertion, it sends a signal to the electric push rod 18. The electric push rod 18 then pushes the buffer pad 19 downwards. At this time, the buffer pad 19 presses down on the lead wire clip, ensuring good contact between the contacts inside the lead wire clip and the contact point 22 at the end of the clip. Next, the operator pulls the injection end of the lead wire to contact the injection end contact point 16. At this point, a qualified lead wire will pass through the injection molding process. The plastic end contact point 16 and the wire clip end contact point 22 form a complete circuit, connecting to the indicator light 14. This causes the indicator light 14 to light up green and the audible and visual alarm 15 to announce that the test is successful. If the wire is unqualified, it cannot form a closed circuit, the indicator light 14 will light up red, and the audible and visual alarm 15 will sound an alarm and indicate that the test is unqualified. After the test is completed, the testing device 13 will send a signal to the electric push rod 18 to move the push rod inside upward. At this time, the operator can remove the wire clip from the wire clip slot 21 to complete the test.
