Description

Technical Field

[0001] The present invention relates to the technical field of electronic detonators, and particularly to an automated production line and method for electronic detonators. Background Art

[0002] As a scientific and technological discipline widely applied in the contemporary engineering field, blasting plays an important role and occupies an important position in various engineering applications, large or small. The essence of blasting is to utilize the huge energy released by the explosion of detonator explosives to better destroy the original structure of objects, greatly saving time and improving economic efficiency. After years of development, numerous varieties of industrial detonators have emerged. Among them, electronic detonators are products obtained by introducing electronic information technology on the basis of traditional industrial detonators. Generally composed of leg wires, detonator bodies, and electronic components, etc., because they use an electronic chip to control the detonation process of the detonator, replacing the delay agent of ordinary delay detonators, they can greatly reduce the influence of delay errors caused by the ignition energy required for the electric ignition structure, thereby achieving high-precision delay setting.

[0003] The patent document with the patent number CN220701991U discloses an electronic detonator packaging structure and an electronic detonator kit for packaging an electronic detonator body with a tail wire clip, a conducting wire, and a detonator. The conducting wire is wound into a coil. The electronic detonator packaging structure includes: a wire accommodating part for accommodating the coil; a third accommodating cavity and a fourth accommodating cavity, which are spaced apart in the length direction and are located inside the coil. The third accommodating cavity is used to accommodate the conducting wire or the detonator close to the detonator, and the fourth accommodating cavity is used to accommodate the conducting wire or the tail wire clip close to the tail wire clip, so that the detonator and the tail wire clip are spaced apart to play a role of fixing and protecting. It solves the problem of low safety such as the detonator and the tail wire clip being prone to mutual collision and knocking during transportation, resulting in damage to the electronic digital detonator or failure of its performance.

[0004] However, during the actual production and transportation process, the inventor found that there are the following problems in the production of existing electronic detonators. It is necessary to wind the leg wires into a wire harness or a coil, connect the two ends of the leg wires to the detonator body and the wire clip respectively, and pack the produced electronic detonators. Some of the above steps need to be completed with the assistance of manual labor, and the degree of automation is low. In addition, the winding structure of the leg wires is unreasonable, which not only occupies a large space, increases the difficulty of packing the electronic detonators into boxes, reduces the number of electronic detonators that can be accommodated in the box, but also the electronic detonators in the box are prone to dislocation movement during transportation, and the detonator body and the wire clip are prone to collision damage. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art, and to achieve full-process automated production by setting a transmission mechanism in conjunction with a winding mechanism, an assembly mechanism, a packaging mechanism, and a boxing mechanism, without the need for manual intervention, and significantly improving production efficiency. During production, the electronic detonator formed by the foot line wrapped around the detonator body and the outside of the wire clip is vacuum-packed in a sealed bag, so that the foot line can be squeezed to tightly wrap the detonator body and the wire clip, thereby improving the limiting effect and the protection effect, and making the vacuum-packed electronic detonator structure reasonable and similar to a cylinder, so that it is convenient to arrange the array and pack it in a packing box, with a large space utilization rate, and reducing collision damage during transportation. This solves the problems of the existing electronic detonator having an unreasonable structure, occupying a large space, having a low degree of automation during production, being difficult to pack into boxes, and being easily damaged during transportation.

[0006] In view of the above technical problems, the following technical solutions are adopted: an automated production line for electronic detonators, comprising an assembly mechanism for assembling a detonator body, a leg wire and a wire clip of an electronic detonator, and also comprising: A conveying mechanism disposed below the assembling mechanism and used to convey the electronic detonator, a winding mechanism, a packaging mechanism and a boxing mechanism sequentially disposed outside the conveying mechanism along the conveying direction of the conveying mechanism, when the winding mechanism wraps the leg wire around the outside of the detonator body and the wire clamp, and cooperates with the packaging mechanism to vacuum-pack the electronic detonator through a sealing bag, the boxing mechanism arranges a plurality of electronic detonator arrays in a packing box and packs them into a box; The winding mechanism includes a wire feeder, a first bending assembly, a second bending assembly, a third bending assembly and a fourth bending assembly which are sequentially arranged on the outside of the conveying mechanism along the conveying direction of the conveying mechanism; when the first bending assembly reciprocates and bends the leg wire conveyed by the wire feeder to the conveying mechanism to form a wire plate, the second bending assembly simultaneously bends the bending part of the leg wire upward, and the upward bending angles of the two adjacent bending parts on the same side of the wire plate are different; when the third bending assembly bends the two ends of the leg wire on both sides of the wire plate to bend the detonator body and the wire clamp assembled by the assembling mechanism to the inside of the wire plate, the fourth bending assembly bends the wire plate upward to form a wire tube surrounding the detonator body and the outside of the wire clamp, and the bending part is located at both ends of the wire tube.

[0007] Preferably, the first bending assembly includes two pushing rods movably arranged on both sides of the conveying mechanism, a positioning plate arranged directly above the conveying mechanism and forming a positioning area between the conveying mechanism, and a pushing plate rotatably arranged on the positioning plate. When the pushing rods move and force the foot lines to bend, the pushing plates push the bent foot lines to fit together and enter the positioning area.

[0008] Preferably, the second bending assembly includes two sliding seats respectively arranged on both sides of the positioning plate and movable along the conveying direction of the conveying mechanism, positioning rods arranged on the sliding seats and movable up and down and inserted into the bending grooves inside the bending positions, bending plates arranged on the sliding seats and movable up and down and cooperating with the positioning plate to bend the bending positions upward, and two first elastic members respectively arranged on both sides of the positioning plate and respectively used to force the two sliding seats to move away from the positioning plate.

[0009] Preferably, the conveying mechanism includes a conveying component arranged below the assembling mechanism, a plurality of bases arranged on the conveying component, positioning grooves arranged on the bases and cooperating with the positioning plate to form the positioning area, and two opening and closing plates rotatably arranged on the bases and used to control the opening and closing of the positioning grooves.

[0010] Preferably, the third bending assembly includes two groups of first clamping arms respectively arranged on both sides of the base and used to clamp both ends of the leg wire, two pushing arms respectively rotatably arranged outside both sides of the base and cooperating with the positioning plate to respectively push the detonator body and the wire clip to bend above the positioning plate, and accommodating grooves formed on the two pushing arms and respectively used to accommodate the detonator body and the wire clip.

[0011] Preferably, the fourth bending assembly includes a limiting member arranged above the base and movable up and down and used to limit the detonator body from separating from the wire plate, a first spade plate arranged above the base and movable and rotatable and having a semi-circular structure, a first limiting plate arranged inside the upper end of the first spade plate, and a second spade plate telescopically arranged inside the first spade plate. When the first spade plate cooperates with the limiting member to shovel up one end of the wire plate to wrap one side of the detonator body and moves out of the limiting member, while the first spade plate rotates, the second spade plate extends to shovel up the other end of the wire plate to wrap the other side of the detonator body.

[0012] Preferably, the limiting member includes a second limiting plate arranged above the base and movable up and down and used to limit the detonator body on the side away from the first spade plate, a third limiting plate movably arranged at the upper end of the limiting plate and used to limit the upper side of the detonator body, and a second elastic member arranged on the second limiting plate and used to force the third limiting plate to move towards the detonator body.

[0013] Preferably, the packaging mechanism includes a vacuum packaging machine disposed outside the conveying mechanism for vacuum packaging the electronic detonator with a sealed bag, a push rod movably and rotatably disposed outside the fourth bending assembly for pushing the electronic detonator into the packaging assembly or the packing box, and two second clamping arms disposed on the push rod in an openable and closable manner for clamping the electronic detonator.

[0014] Preferably, the boxing mechanism includes a case sealer disposed outside the packaging mechanism, a support table movably disposed between the packaging mechanism and the case sealer, and a tipping bucket rotatably disposed on the support table for supporting and tipping the packing box.

[0015] The present invention also provides an automated production method for electronic detonators. Based on the above-mentioned automated production line for electronic detonators, it includes the following steps: Step 1: Wiring process. During the process of the wire feeder conveying the leg wires to the conveying mechanism, the first bending assembly reciprocally bends the leg wires to form the wire board, and at the same time, cooperates with the second bending assembly to bend the bent parts of the leg wires upward, and both sides of the formed wire board respectively extend out the two ends of the leg wires. Step 2: Assembly process. The conveying mechanism conveys the wire board to the assembly mechanism, and after respectively assembling the detonator body and the wire clamp to the two ends of the leg wires, the third bending assembly bends the two ends of the leg wires until the detonator body and the wire clamp are located inside the wire board. Step 3: Packaging process. After the fourth bending assembly bends the wire board into the wire tube and cooperates with the bending part to wrap the outside of the detonator body and the wire clamp, the packaging mechanism vacuum packages the electronic detonator through the sealed bag, thereby squeezing the leg wires, the detonator body and the wire clamp to fit tightly with each other. Step 4: Boxing process. The packaged electronic detonators are horizontally inserted into the packing box through the boxing mechanism. When multiple electronic detonators are arranged in an array in the packing box until the packing box is filled, the boxing mechanism flips the packing box with the electronic detonators to the vertical state, and then the boxing mechanism seals the packing box and outputs it, completing the production.

[0016] The beneficial effects of the present invention: (1)In the present invention, a conveying mechanism is provided to cooperate with a wire winding mechanism, an assembling mechanism, a packaging mechanism, and a boxing mechanism to achieve fully automated production. There is no need for manual intervention throughout the process, and the production efficiency is significantly improved. During the wire winding process, the first bending component, the second bending component, the third bending component, and the fourth bending component cooperate with each other in the production line to bend the leg wire step by step at multiple angles. After the leg wire is finally formed and the wire outlet tube and the bending part wrap around the outside of the detonator body and the wire clamp, a sealing bag is used to vacuum package the electronic detonator, so as to squeeze the wire tube and the bending part to further tightly wrap the detonator body and the wire clamp, improving the limiting effect and the protection effect, preventing collision damage or loosening of the connection caused by shaking during transportation, and making the structure of the vacuum-packaged electronic detonator reasonable and similar to a cylindrical shape, occupying less space. Furthermore, it can be arranged in an array and packed in a packing box to ensure the maximum utilization rate of the space in the box and reduce misalignment movement or even collision damage during transportation; (2)In the present invention, after the leg wire is bent by setting a push rod, the push rod moves out and cooperates with a sliding seat and a positioning rod to insert into a bending groove for positioning the bending part, avoiding misalignment movement of the leg wire. At the same time, when the rotating push plate pushes the leg wire into the positioning area, the sliding seat moves synchronously and the bending plate moves upward to squeeze the bending part through the positioning plate to bend upward synchronously, avoiding interference with the previously bent bending part. And when the positioning rod moves out, the bending part cooperates with the positioning plate to limit the movement of the leg wire, and the first elastic member forces the sliding seat to reset. By repeating this process, the wire plate formed by repeatedly bending the leg wire can be positioned in the positioning area. The structure is simple and the bending effect is good; (3)In the present invention, by setting a limiting member to cooperate with the first shovel plate and the second shovel plate with a semi-circular structure, the two ends of the wire plate are forced to bend and wrap around the outside of the detonator body, which is convenient to push the electronic detonator into the vacuum packaging machine by a push rod. With the assistance of the second clamping arm and the moving support platform, the vacuum-packaged electronic detonator can be clamped out of the vacuum packaging machine and horizontally inserted into the packing box in an array. The electronic detonators are stacked in the packing box under the action of gravity, which is convenient for packing into a box. And with the help of a tipping bucket, the electronic detonators can be flipped to a vertical state along with the packing box, which is convenient for the subsequent sealing machine to seal the box and also avoids extrusion between the electronic detonators during transportation; In summary, when the electronic detonator automatic production line produces electronic detonators, it has a high degree of automation, reduces the difficulty of packing into a box, and the produced electronic detonators have a reasonable structure, occupy less space, and are not easily damaged during transportation. It is particularly suitable for the technical field of electronic detonators. Brief Description of the Drawings

[0028] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the drawings.

[0029] Embodiment 1 As Figures 1 - 2 And Figures 8 - 12 Shown, an automated production line for electronic detonators includes an assembly mechanism 1 for assembling the detonator body 61, leg wire 62, and wire clip 65 of the electronic detonator 6, and further includes: A conveying mechanism 2 disposed below the assembling mechanism 1 and used for conveying electronic detonators 6, a wire winding mechanism 3, a packaging mechanism 4, and a boxing mechanism 5 sequentially arranged outside the conveying mechanism 2 along the conveying direction of the conveying mechanism 2. When the wire winding mechanism 3 winds the leg wire 62 around the outside of the detonator body 61 and the wire clip 65, and cooperates with the packaging mechanism 4 to vacuum-pack the electronic detonator 6 with a sealed bag, the boxing mechanism 5 arranges multiple electronic detonators 6 in an array in the packing box 7 and packs them into a box. The wire winding mechanism 3 includes a wire feeder 31, a first bending assembly 32, a second bending assembly 33, a third bending assembly 34, and a fourth bending assembly 35 sequentially arranged outside the conveying mechanism 2 along the conveying direction of the conveying mechanism 2. When the first bending assembly 32 reciprocally bends the leg wire 62 conveyed by the wire feeder 31 onto the conveying mechanism 2 to form a wire board 63, the second bending assembly 33 simultaneously bends the bending portion 621 of the leg wire 62 upward, and the upward bending angles of two adjacent bending portions 621 on the same side of the wire board 63 are different. When the third bending assembly 34 bends the two ends of the leg wire 62 on both sides of the wire board 63 to bend the detonator body 61 and the wire clip 65 assembled by the assembling mechanism 1 to the inside of the wire board 63, the fourth bending assembly 35 bends the wire board 63 upward to form a wire tube 64 surrounding the outside of the detonator body 61 and the wire clip 65, and the bending portion is located at both ends of the wire tube 64.

[0030] In this embodiment, by setting the coordinated operation of the first bending assembly 32, the second bending assembly 33, the third bending assembly 34, and the fourth bending assembly 35 in the production line, and cooperating with the conveying mechanism 2 to ensure that the leg wire 62 conveyed by the wire feeder 31 surrounds the outside of the detonator body 61 and the wire clip 65 assembled by the assembling mechanism 1, the occupied space of the electronic detonator 6 is reduced, the uneven tightness or shape deviation caused by manual wire winding is avoided, the accuracy and consistency of wire winding are ensured. The leg wire 62 is bent step by step at multiple angles, so that the leg wire 62 is first reciprocally bent to form a wire board 63, which is convenient for stretching the leg wire 62 during later use. Then, after finally forming the wire tube 64 and the bending portion wrapping the outside of the detonator body 61 and the wire clip 65, the packaging mechanism 4 uses a sealed bag to vacuum-pack the electronic detonator 6. This not only squeezes the wire tube 64 and the bending portion to further tightly wrap the detonator body 61 and the wire clip 65, improving the limiting effect and the protection effect, preventing collision damage or loosening of the connection caused by shaking during transportation, but also reducing the risk of moisture absorption or oxidation of the electronic detonator 6, prolonging the storage life and ensuring the use stability. Moreover, the vacuum-packed electronic detonator 6 has a reasonable structure and is similar to a cylinder, and then it can be automatically arranged in an array and packed in the packing box 7 in cooperation with the boxing mechanism 5, ensuring the maximum utilization rate of the space in the box, while reducing the occurrence of misalignment movement or even collision damage during transportation. The whole production process is fully automated and does not require manual intervention throughout the process, significantly improving the production efficiency.

[0031] It should be noted that the wire feeder 31 itself and its installation method are both prior arts and will not be elaborated in detail here.

[0032] Further, as Figure 3 shown, the first bending assembly 32 includes two push rods 321 respectively movably arranged on both sides of the conveying mechanism 2, a positioning plate 322 arranged directly above the conveying mechanism 2 and forming a positioning area 323 with the conveying mechanism 2, and a push plate 324 rotatably arranged on the positioning plate 322. After the push rod 321 moves and forces the leg wire 62 to bend, the push plate 324 pushes the bent leg wires 62 to fit together and enter the positioning area 323.

[0033] In this embodiment, after the leg wire 62 is bent by setting the push rod 321, the rotating push plate 324 is used to guide and push the bent leg wire 62 between the positioning plate 322 and the conveying mechanism 2, and thus the wire board 63 formed by repeatedly bending the leg wire 62 is positioned in the positioning area 323 by reciprocating.

[0034] It should be noted that the two push rods 321 are connected to each other and driven simultaneously. When one push rod 321 pushes the leg wire 62 to bend, the other push rod 321 withdraws from the bending point 621.

[0035] Further, as Figure 3 shown, the second bending assembly 33 includes two sliding seats 331 respectively movably arranged along the conveying direction of the conveying mechanism 2 on both sides of the positioning plate 322, a positioning rod 332 movably arranged up and down on the sliding seat 331 and inserted into the bending groove 622 inside the bending point 621, a bending plate 333 movably arranged up and down on the sliding seat 331 and used in cooperation with the positioning plate 322 to bend the bending point 621 upward, and two first elastic members 334 respectively arranged on both sides of the positioning plate 322 and used to force the two sliding seats 331 to move away from the positioning plate 322.

[0036] In this embodiment, the sliding seat 331 is set to cooperate with the positioning rod 332 to position the bending point 621, avoiding the misalignment movement of the leg wire 62 when the push rod 321 makes the next bend. Also, when the push plate 324 pushes the leg wire 62 and the bending plate 333 moves upward to squeeze the bending point 621 upward through the positioning plate 322, the positioning rod 332 moves synchronously with the sliding seat 331, avoiding interference with the previously bent bending point 621. After the adjacent two bending points 621 are staggered, the positioning rod 332 moves out. During the subsequent conveying process of the conveying mechanism 2, the upward bent bending point 621 cooperates with the positioning plate 322 to limit the movement of the leg wire 62, and the first elastic member 334 forces the sliding seat 331 to reset, facilitating the next bending use.

[0037] It should be noted that in order to avoid excessive bending of the foot line 62, a bending groove 622 is formed inside the bending portion 621 when the foot line 62 is bent. Therefore, the upward bending angles of two adjacent bending portions 621 on the same side of the wire board 63 are different, which avoids interference between the bending portions 621 and facilitates the bending of the wire board 63 into a wire tube 64.

[0038] Furthermore, as Figures 2 - 3 shown, the conveying mechanism 2 includes a conveying component 21 arranged below the assembling mechanism 1, a plurality of bases 22 arranged on the conveying component 21, a positioning groove 23 arranged on the base 22 and cooperating with the positioning plate 322 to form a positioning area 323, and two opening and closing plates 24 rotatably arranged on the base 22 and used for controlling the opening and closing of the positioning groove 23.

[0039] In this embodiment, by setting the opening and closing plate 24 to control the opening and closing of the positioning groove 23 on the base 22 and cooperating with the conveying component 21 to convey the base 22 to move, after the bent foot line 62 gradually enters the positioning groove 23, the wire board 63 can be positioned.

[0040] Specifically, when the conveying component 21 conveys one end of the positioning groove 23 to the lower part of the positioning plate 322 along with the base 22, the clamping plate controls the other end of the positioning groove 23 to open, and then the bent foot line 62 can enter between the positioning plate 322 and the positioning groove 23. Until the foot line 62 is bent into the wire board 63, the clamping plate closes the positioning groove 23 to position the wire board 63 between the positioning plate 322 and the positioning groove 23.

[0041] It should be noted that the conveying component 21 can be a conveyor belt, and its itself and the installation method are both prior arts, so no detailed description will be given here.

[0042] Furthermore, as Figures 3 - 4 shown, the third bending component 34 includes two groups of first clamping arms 341 respectively arranged on both sides of the base 22 in an opening and closing manner and used for clamping both ends of the foot line 62, two pushing arms 342 respectively rotatably arranged outside both sides of the base 22 and cooperating with the positioning plate 322 to respectively push the detonator body 61 and the wire clamp 65 to be bent above the positioning plate 322, and accommodating grooves 343 formed on the two pushing arms 342 and respectively used for accommodating the detonator body 61 and the wire clamp 65.

[0043] In this embodiment, by setting the first clamping arm 341 to clamp both ends of the leg wire 62, it is convenient for the assembling mechanism 1 to assemble the detonator body 61 and the wire clamp 65. At the same time, when the pushing arm 342 pushes the detonator body 61 and the wire clamp 65, the leg wire 62 is prevented from being misaligned. Additionally, the accommodating groove 343 is used to position the detonator body 61 and the wire clamp 65, enabling the detonator body 61 and the wire clamp 65 to be bent above the positioning plate 322, that is, above the wire board 63. Moreover, when the first bending assembly 32 bends the leg wire 62, the first clamping arm 341 clamps the end of the leg wire 62 for limiting.

[0044] It should be noted that the pushing arm 342 can be of a J-shaped or L-shaped structure, and the bent portion 621 of the pushing plate 324 is used to bend the leg wire 62 above the positioning plate 322.

[0045] Furthermore, as Figures 4 - 7 shown, the fourth bending assembly 35 includes a limiting member 354 that is movably disposed above the base 22 and is used to prevent the detonator body 61 from detaching from the wire board 63, a first shovel plate 351 that is movably and rotatably disposed above the base 22 and has a semi-circular structure, a first limiting plate 352 disposed inside the upper end of the first shovel plate 351, and a second shovel plate 353 that is telescopically disposed inside the first shovel plate 351. When the first shovel plate 351 cooperates with the limiting member 354 to shovel up one end of the wire board 63 to wrap one side of the detonator body 61 and then moves out of the limiting member 354, while the first shovel plate 351 rotates, the second shovel plate 353 extends to shovel up the other end of the wire board 63 to wrap the other side of the detonator body 61.

[0046] In this embodiment, by setting the limiting member 354 to cooperate with the first shovel plate 351 to shovel up one end of the wire board 63 until one end of the wire board 63 abuts against the first limiting plate 352, and then with the assistance of the second shovel plate 353 to shovel up the other end of the wire board 63, the wire board 63 is wrapped around the outside of the detonator body 61.

[0047] Specifically, the limiting member 354 moves downward to limit the detonator body 61 and opens a switching plate 24 near the detonator body 61. During the transmission of the transmission assembly 21, one end of the first shovel plate 351 enters the positioning groove 23 through the switching plate 24. The wire plate 63 and the detonator body 61 are shoveled into the first shovel plate 351, and one end of the wire plate 63 is forced to wrap one side of the detonator body 61. Until one end of the wire plate 63 abuts against the first positioning plate 322 for positioning, the limiting member 354 moves upward to release the restriction. While the first shovel plate 351 rotates, the second shovel plate 353 extends, so that the detonator body 61 is restricted between the first shovel plate 351 and the second shovel plate 353, and the wire plate 63 can be continuously shoveled up and bent until the wire plate 63 completely moves out of the positioning plate 322 and the first shovel plate 351 moves away from the positioning plate 322. Another switching plate 24 opens, and the other end of the first shovel plate 351 can shovel up the other end of the wire plate 63 through the other switching plate 24 until the first shovel plate 351 and the second shovel plate 353 are closed, so that the wire plate 63 can be bent into a wire tube 64 that wraps around the outside of the detonator body 61 and the wire clip 65.

[0048] It should be noted that the ends of the first shovel plate 351 and the second shovel plate 353 are both provided with inclined surface structures to facilitate shoveling up the wire plate 63.

[0049] Furthermore, as Figures 4 - 7 shown, the limiting member 354 includes a second limiting plate 355 that is movably arranged up and down above the base 22 and is used to limit the side of the detonator body 61 away from the first shovel plate 351, a third limiting plate 356 that is movably arranged at the upper end of the limiting plate and is used to limit the upper side of the detonator body 61, and a second elastic member 357 that is arranged on the second limiting plate 355 and is used to force the third limiting plate 356 to move towards the detonator body 61.

[0050] In this embodiment, by setting the second limiting plate 355 to cooperate with the third limiting plate 356, when the first shovel plate 351 shovels up the detonator body 61, it is possible to prevent the detonator body 61 from detaching from the wire plate 63. After the first shovel plate 351 rotates and squeezes the third limiting plate 356 to move, so that the detonator body 61 is restricted between the first shovel plate 351 and the second shovel plate 353, the second limiting plate 355 moves upward and, with the assistance of the second elastic member 357, realizes the automatic reset of the third limiting plate 356, which is convenient for the next positioning use.

[0051] It should be noted that the first elastic member 334 and the second elastic member 357 can be a spiral spring, a leaf spring or a rubber spring, etc. Their own and installation methods are all prior arts and will not be elaborated in detail here.

[0052] Furthermore, as Figure 1 and Figure 13As shown in the figure, the packaging mechanism 4 includes a vacuum packaging machine 41 disposed outside the conveying mechanism 2 and used for vacuum packaging the electronic detonator 6 with a sealed bag, a push rod 321 movably and rotatably disposed outside the fourth bending assembly 35 and used for pushing the electronic detonator 6 into the packaging assembly or the packing box 7, and two second clamping arms 43 disposed on the push rod 321 in an openable and closable manner and used for clamping the electronic detonator 6.

[0053] In this embodiment, by providing the push rod 321, the electronic detonator 6 in the fourth bending assembly 35 can be pushed into the vacuum packaging machine 41. With the assistance of the second clamping arms 43 and by rotating the push rod 321, the vacuum-packaged electronic detonator 6 can be clamped from the vacuum packaging machine 41 into the boxing mechanism 5. Then, the second clamping arms 43 are opened, and the push rod 321 can completely push the electronic detonator 6 into the boxing mechanism 5.

[0054] It should be noted that both the vacuum packaging machine 41 itself and its installation method are prior arts and will not be elaborated in detail here; in addition, the sealing tape itself is a prior art and is not shown in the drawings and will not be elaborated in detail here.

[0055] Furthermore, as Figure 1 and Figures 12 - 13 shown, the boxing mechanism 5 includes a box sealing machine 51 disposed outside the packaging mechanism 4, a support table 52 movably disposed between the packaging mechanism 4 and the box sealing machine 51, and a tipping bucket 53 rotatably disposed on the support table 52 and used for supporting and tipping the packing box 7.

[0056] In this embodiment, by providing the support table 52 to move the packing box 7 in cooperation with the packaging mechanism 4, the electronic detonators 6 vacuum-packaged by the packaging mechanism 4 are horizontally arrayed and inserted into the packing box 7. The electronic detonators 6 are stacked in the packing box 7 under the action of gravity, which is convenient for packing into boxes, avoiding the need for positioning during packing. In cooperation with the tipping bucket 53, the electronic detonators 6 can be tipped to the vertical state together with the packing box 7, and the electronic detonators 6 automatically move to the bottom of the packing box 7 under the action of gravity, which is convenient for the subsequent box sealing machine 51 to seal the box and also avoids extrusion between the electronic detonators 6 during transportation.

[0057] It should be noted that both the box sealing machine 51 itself and its installation method are prior arts and will not be elaborated in detail here.

[0058] Embodiment 2 As Figures 1 - 2 、 Figures 8 - 12 and Figure 14 shown, the present invention also provides an automatic production method for electronic detonators. Based on the automatic production line for electronic detonators in Embodiment 1, it includes the following steps: Step 1: Winding process. During the process of the wire feeder 31 feeding the leg wire 62 to the conveying mechanism 2, the first bending assembly 32 reciprocally bends the leg wire 62 to form the wire board 63, and at the same time, cooperates with the second bending assembly 33 to bend the bending part 621 of the leg wire 62 upward, and both sides of the formed wire board 63 respectively extend out from both ends of the leg wire 62. Step 2: Assembly process. The conveying mechanism 2 conveys the wire board 63 to the assembly mechanism 1, and after respectively assembling the detonator body 61 and the wire clip 65 to both ends of the leg wire 62, the third bending assembly 34 bends both ends of the leg wire 62 until the detonator body 61 and the wire clip 65 are located inside the wire board 63. Step 3: Packaging process. After the fourth bending assembly bends the wire board 63 into a wire tube 64 and cooperates with the bending part to wrap the outside of the detonator body 61 and the wire clip 65, the packaging mechanism 4 vacuum-packages the electronic detonator 6 through a sealed bag, thereby squeezing the leg wire 62, the detonator body 61 and the wire clip 65 to fit together. Step 4: Boxing process. The packaged electronic detonator 6 is horizontally inserted into the packing box 7 through the boxing mechanism 5. Until when multiple electronic detonators 6 are arranged in an array in the packing box 7 and fill the packing box 7, the boxing mechanism 5 flips the electronic detonator 6 and the packing box 7 to the vertical state, and then the boxing mechanism 5 seals the packing box 7 and outputs it, completing the production.
