[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0038] The present application provides an explosion-proof assembly device. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 1 , Figure 2 which are the structural schematic diagrams of the explosion-proof assembly device provided by the embodiments of the present application. Figure 3 which is the top view of the internal structure of the explosion-proof assembly device provided by the embodiments of the present application.

[0039] Please refer to Figure 1 , Figure 2 , Figure 3 . The explosion-proof assembly device includes: an explosion-proof box body 1, a rotary disk 2, and an explosion-proof barrier mechanism 3. Among them, the rotary disk 2 is rotatably arranged at the inner bottom of the explosion-proof box body 1, and a plurality of fixed bases 11 arranged at intervals are provided on the rotary disk 2; the explosion-proof barrier mechanism 3 is arranged in the explosion-proof box body 1, the explosion-proof barrier mechanism 3 is located above the rotary disk 2, and the explosion-proof barrier mechanism 3 divides the explosion-proof box body 1 into a first explosion-proof area and a second explosion-proof area; a loading and unloading station 10 and a pre-tightening station 20 are arranged in the first explosion-proof area, a pressing station 30 and a tightening station 40 are arranged in the second explosion-proof area, and the fixed bases 11 on the rotary disk 2 sequentially pass through the loading and unloading station 10, the pre-tightening station 20, the pressing station 30, and the tightening station 40.

[0040] Among them, the space enclosed by the explosion-proof box body 1 has an explosion-proof function. The explosion-proof box body 1 is divided into a first explosion-proof area and a second explosion-proof area by the explosion-proof barrier mechanism 3, and combined with the rotary disk 2, it can realize the transfer of the initiator between different stations in the first explosion-proof area and the second explosion-proof area, and can realize the explosion-proof requirements of different stations matching different explosion-proof grades, improving the safety performance in the production process of the initiator.

[0041] Preferably, the first explosion-proof area is an explosion-proof area of general level, and the second explosion-proof area is an explosion-proof area of important level. Generally, no faults or explosions will occur during the loading and unloading operations of explosive devices or the pre-fastening operations of fasteners at the loading and unloading station 10 and the pre-fastening station 20. Therefore, they are set in the first explosion-proof area. When the pressing station 30 and the tightening station 40 press or tighten and assemble explosive devices, it is easy to cause faults or explosions of explosive devices. Therefore, they are set in the second explosion-proof area. Such zonal management can not only reduce the explosion-proof cost of the explosion-proof box 1 but also meet the explosion-proof requirements of different stations.

[0042] Please refer to Figure 2 、 Figure 4 , the explosion-proof barrier mechanism 3 includes an explosion-proof partition 31 and two explosion-proof doors 32. The explosion-proof doors 32 are arranged on the rotation path of the fixed base 11 on the turntable 2. When the explosion-proof doors 32 are opened, the turntable 2 rotates to drive the fixed base 11 to switch between the first explosion-proof area and the second explosion-proof area. It can be understood that the turntable 2 is circular, and a rotating shaft 21 is provided at its center position. The rotation path of the fixed base 11 on the turntable 2 is a circular path. Therefore, the explosion-proof doors 32 are arranged on the circular path. When the fixed base 11 switches between the first explosion-proof area and the second explosion-proof area, just open the explosion-proof doors 32. After completing the position switch of the fixed base 11, close the explosion-proof doors 32. When the explosion-proof doors 32 are closed, the fixed base 11 is separated within the general explosion-proof area and the key explosion-proof area, and the explosion-proof barrier mechanism 3 can also completely isolate the first explosion-proof area and the second explosion-proof area.

[0043] Please refer to Figure 4 , the explosion-proof barrier mechanism 3 further includes a transverse sliding rail 33 and a driving component 34. The transverse sliding rail 33 is horizontally installed on the explosion-proof partition 31. The driving component 34 is installed on the explosion-proof partition 31 and is located above the transverse sliding rail 33. The top of the explosion-proof door 32 is slidably connected to the transverse sliding rail 33, and the driving component 34 drives the explosion-proof door 32 to slide along the transverse sliding rail 33 to control the opening or closing of the explosion-proof door 32.

[0044] Please refer to Figure 4 , the explosion-proof barrier mechanism 3 further includes a first proximity switch 35 and a second proximity switch 36. The first proximity switch 35 is used to detect and judge whether the explosion-proof door 32 is opened, and the second proximity switch 36 is used to detect and judge whether the explosion-proof door 32 is closed. Specifically, the first proximity switch 35 is arranged on the explosion-proof partition 31 and is located at the fully opened position of the explosion-proof door 32, and the second proximity switch 36 is arranged on the explosion-proof partition 31 and is located at the fully closed position of the explosion-proof door 32. In this way, the opening or closing state of the explosion-proof door 32 can be detected and obtained through the first proximity switch 35 and the second proximity switch 36.

[0045] Please refer to Figure 2 、 Figure 3 、 Figure 4, the explosion-proof partition 31 is perpendicular to the rotary disk 2, and the orthographic projection of the explosion-proof partition 31 on the rotary disk 2 coincides with the radius of the rotary disk 2. It can be understood that a rotating shaft 21 is provided at the center position of the rotary disk 2. The explosion-proof partition 31 can be divided into two sub-partitions, and the orthographic projection of each sub-partition on the rotary disk 2 coincides with the radius of the rotary disk 2. Therefore, the two sub-partitions are connected at the position corresponding to the rotating shaft 21, and the included angle between the two sub-partitions can be set based on the required areas of the first explosion-proof area and the second explosion-proof area. The explosion-proof partition 31 cooperates with the rotary disk 2 to complete intermittent opening and closing. After being completely closed, the second explosion-proof area is an independent space, meeting the requirements of safety explosion isolation.

[0046] Please refer to Figure 1 , Figure 2 , the explosion-proof assembly equipment further includes a top plate 4. The top plate 4 is disposed on the top of the explosion-proof box 1, and a pressure relief hole 41 is provided on the top plate 4 corresponding to the second explosion-proof area. The top plate 4 can provide equipment or components for realizing the corresponding functions of the loading and unloading station 10, the pre-fastening station 20, the press-fitting station 30, and the tightening station 40. The pressure relief hole 41 is provided on the top plate 4 to facilitate upward pressure relief of the high-pressure impact in case of explosion, protecting the surrounding safety.

[0047] Please refer to Figure 1 , Figure 2 , on the side of the explosion-proof box 1 corresponding to the second explosion-proof area, an upper enclosing plate 12 and a lower enclosing plate 13 are provided. An armored door 14 is installed on the upper enclosing plate 12, and an observation window 15 is provided on the armored door 14. The material of the observation window 15 includes explosion-proof glass. The explosion-proof partition 31, the upper enclosing plate 12, the lower enclosing plate 13, and the top plate 4 in the second explosion-proof area form an explosion-proof armor. The thickness of the explosion-proof armor is set according to the maximum TNT equivalent of the current pyrotechnic device. The observation window 15 is provided with explosion-proof glass on the armored door 14, and the armored door 14 is set as a detachable structure, facilitating maintenance and repair.

[0048] Please refer to Figure 2 , Figure 5 , the explosion-proof assembly equipment further includes an indexing disk rotating device 5. The indexing disk rotating device 5 is fixed on the explosion-proof box 1, and the indexing disk rotating device 5 is used to drive the rotary disk 2 to perform intermittent rotary motion. The indexing disk rotating device 5 drives the rotary disk 2 to rotate once, driving the pyrotechnic device fixed on the fixed base 11 on the rotary disk 2 to flow into the next station. Each time the indexing disk rotating device 5 drives the rotary disk 2 to rotate, the explosion-proof door 32 is opened. Each time the indexing disk rotating device 5 drives the rotary disk 2 to complete rotation, the explosion-proof door 32 is closed.

[0049] Please refer to Figure 2 , Figure 5, the explosion-proof assembly equipment further includes a lower partition plate 16. The lower partition plate 16 is provided with a circular hole, and the rotary disk 2 is arranged in the circular hole. The upper surface of the lower partition plate 16 is flush with the upper surface of the rotary disk 2. The indexing disk rotary device 5 is arranged below the lower partition plate 16, and the indexing disk rotary device 5 is connected to the rotating shaft 21 of the rotary disk 2. The way that the upper surface of the lower partition plate 16 is flush with the upper surface of the rotary disk 2 facilitates the loading and unloading operations.

[0050] Please refer to Figure 5 , in order to facilitate connecting the indexing disk rotary device 5 to the lower part of the lower partition plate 16, the indexing disk rotary device 5 is set to be fixed on a fixing frame 51, and the fixing frame 51 is connected to the lower surface of the lower partition plate 16 through a plurality of connecting columns 52.

[0051] Please refer to Figure 3 , four fixing bases 11 are arranged on the rotary disk 2. The fixing bases 11 are equally spaced on the edge of the rotary disk 2. The explosion-proof barrier mechanism 3 separates two fixing bases 11 in the first explosion-proof area and separates two fixing bases 11 in the second explosion-proof area. Preferably, the orthographic projection of the explosion-proof partition plate 31 on the rotary disk 2 coincides with the diameter of the rotary disk 2. In this way, when the explosion-proof partition plate 31 is divided into two sub-partition plates, the included angle between the two sub-partition plates is 180 degrees, and the areas of the rotary disk 2 in the first explosion-proof area and the second explosion-proof area are the same.

[0052] Please refer to Figure 1 , Figure 2 , Figure 3 , the loading and unloading station 10 is provided with a height detection component 6, the pre-fastening station 20 is provided with a pre-fastening component 7, the press-fitting station 30 is provided with a press-fitting component 8, and the tightening station 40 is provided with a tightening component 9; after the rotary disk 2 stops rotating, the four fixing bases 11 are respectively arranged corresponding to the height detection component 6, the pre-fastening component 7, the press-fitting component 8, and the tightening component 9.

[0053] Among them, the height detection component 6 can perform height detection on the initiator after the tightening component 9 at the tightening station 40 completes the tightening assembly of the initiator, so as to judge whether the assembly of the initiator is qualified. When the assembly height of the initiator does not meet the preset height threshold, a tightening operation is performed again. When the assembly height of the initiator meets the preset height threshold, the qualified initiator is unloaded.

[0054] Please refer to Figure 6 , the press-fitting component 8 includes a press-fitting drive component 81, a bracket 82, a sound detection device 83, and a press head 84. The bracket 82 is fixed on the top of the explosion-proof box 1. The press-fitting drive component 81 and the sound detection device 83 are fixed on the bracket 82. The press head 84 is installed below the press-fitting drive component 81. The press-fitting drive component 81 drives the press head 84 to press-fit the initiator, and the sound detection device 83 is used to detect the decibel level and trigger corresponding alarms and disposal methods according to the decibel level.

[0055] Among them, the bracket 82 is fixed on the top plate 4, and the press-fitting drive assembly 81 is fixed on the bracket 82 and located outside the explosion-proof box body 1, which can be replaced for maintenance and repair. The sound detection device 83 is located inside the explosion-proof box body 1. When a failure or explosion occurs during press-fitting, it can trigger corresponding levels of alarm and disposal methods according to the decibel level. The pressing head 84 is installed below the press-fitting drive assembly 81 and is used to directly contact and press-fit the initiator. The pressing head 84 is set in a quick-change manner and can be quickly installed and switched according to the production of different initiators.

[0056] Please refer to Figure 7 , the tightening assembly 9 includes a lifting device 91, a tightening shaft 92, a vision component 93, a transverse movement component 94, and a bit 95. The transverse movement component 94 is installed on the top of the explosion-proof box body 1. The lifting device 91 is fixed on the transverse movement component 94. The transverse movement component 94 drives the lifting device 91 to move horizontally. The tightening shaft 92 is fixed on the lifting device 91. The lifting device 91 drives the tightening shaft 92 to move longitudinally. The bit 95 is installed at the end of the tightening shaft 92. The vision component 93 is installed on the transverse movement component 94. The vision component 93 is electrically connected to the lifting device 91, the transverse movement component 94, and the tightening shaft 92. The vision component 93 drives the lifting device 91 and the transverse movement component 94 through the image to control the bit 95 to insert into the initiator and control the tightening shaft 92 to drive the bit 95 to rotate to complete the assembly of the initiator.

[0057] Among them, the transverse movement component 94, the lifting device 91, and the vision component 93 complete the switching between the tightening action and the vision guidance. When the initiator reaches the current position, the vision component 93 takes a photo and gives guidance data to guide the bit on the tightening shaft 92 to correctly insert into the initiator. The tightening shaft 92 is provided with a torque sensor for monitoring the torque output. The bit 95 is set in a quick-change manner and can be quickly installed and switched according to the production of different initiators.

[0058] The embodiment of the present application further provides a method for assembling explosive devices in an explosion-proof manner. Using the explosion-proof assembly equipment described in any one of the foregoing paragraphs, the method for assembling explosive devices in an explosion-proof manner includes: obtaining a first explosion-proof area and a second explosion-proof area according to the position of the explosion-proof barrier mechanism 3 in the explosion-proof box body 1; setting a loading and unloading station 10 and a pre-fastening station 20 in the first explosion-proof area, and setting a pressing station 30 and a tightening station 40 in the second explosion-proof area. The loading and unloading station 10, the pre-fastening station 20, the pressing station 30, and the tightening station 40 are sequentially arranged along the edge of the rotary table 2; detecting whether the explosion-proof barrier mechanism 3 is closed. When the explosion-proof barrier mechanism 3 is closed, loading the explosive device components onto the fixed base 11 corresponding to the loading and unloading station 10, and simultaneously pre-fastening the explosive device components that have been loaded onto the fixed base 11 corresponding to the pre-fastening station 20, simultaneously pressing the explosive device components that have been pre-fastened on the fixed base 11 of the pressing station 30, and simultaneously tightening and assembling the explosive device components that have been pre-fastened on the fixed base 11 corresponding to the tightening station 40; determining whether the preset operations have been completed at the loading and unloading station 10, the pre-fastening station 20, the pressing station 30, and the tightening station 40. If not, waiting for a preset duration. If so, controlling the explosion-proof barrier mechanism 3 to open, controlling the rotary table 2 to rotate a preset angle, and then controlling the explosion-proof barrier mechanism 3 to close; detecting again whether the explosion-proof barrier mechanism 3 is closed, and sequentially completing the preset operations at the loading and unloading station 10, the pre-fastening station 20, the pressing station 30, and the tightening station 40 synchronously.

[0059] It is understandable that when the explosion-proof assembly equipment is in use, first, when the explosion-proof barrier mechanism 3 is closed, the pyrotechnic component is loaded onto the fixed base 11 corresponding to the loading and unloading station 10. If, after the operation of loading the pyrotechnic component is completed and the remaining stations have completed the preset operations, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is opened, and the indexing turntable device 5 is controlled to drive the turntable 2 to rotate, so as to transfer the loaded pyrotechnic component to the pre-fastening station 20. Then, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is closed, and the pre-fastening of the loaded pyrotechnic component is completed on the fixed base 11 corresponding to the pre-fastening station 20. If, after the operation of pre-fastening the pyrotechnic component is completed and the remaining stations have completed the preset operations, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is opened, and the pre-fastened pyrotechnic component is transferred to the press-fitting station 30. Then, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is closed, and the pyrotechnic component pre-fastened on the fixed base 11 of the press-fitting station 30 is press-fitted. If, after the operation of press-fitting the pyrotechnic component is completed and the remaining stations have completed the preset operations, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is opened, and the press-fitted pyrotechnic component is transferred to the tightening station 40. Then, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is closed, and the pyrotechnic component pre-fastened on the fixed base 11 corresponding to the tightening station 40 is tightened and assembled. If, after the operation of tightening and assembling the pyrotechnic component is completed and the remaining stations have completed the preset operations, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is opened, and the tightened and assembled pyrotechnic component is transferred to the loading and unloading station 10. Then, the explosion-proof door 32 of the explosion-proof barrier mechanism 3 is closed, and the height of the tightened and assembled pyrotechnic component is detected at the loading and unloading station 10 to determine whether it is qualified. If it is qualified, it is unloaded. If it is unqualified, the tightening operation is performed again in a loop.

[0060] In the explosion-proof assembly equipment and the pyrotechnic explosion-proof assembly method of the embodiments of the present application, through the above technical solution, the explosion-proof box body 1 can be divided into a first explosion-proof area and a second explosion-proof area by the explosion-proof barrier mechanism 3, and combined with the turntable 2, the transfer of pyrotechnics between different stations in the first explosion-proof area and the second explosion-proof area can be realized, and the explosion-proof requirements of different stations with different explosion-proof grades can be met, improving the safety performance in the production process of pyrotechnics.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features.
