Description

Technical Field

[0001] This invention relates to the field of civilian explosives production equipment, and particularly to a production line for coating electronic detonators and electronic ignition elements. Background Technology

[0002] In the manufacturing process of electronic detonators, one step involves coating the electronic ignition element with a paste-like agent / moisture-proof paint. After coating, the element is dried to solidify the agent / moisture-proof paint onto its surface. To ensure effective coating, existing technologies generally employ a multi-coating process, requiring multiple coating units on the production line. For example, Chinese utility model patent application number 202122428861.8 discloses an automatic coating head production equipment for electronic detonator ignition elements. This equipment includes, in sequence, an ignition element feeding unit, an ignition element transfer unit, a primary coating unit, a primary drying unit, a secondary coating unit, a secondary drying unit, a moisture-proof coating unit, a moisture-proof coating drying unit, and an ignition element unloading unit. Because two sets of coating units and two sets of coating-drying units are required, the entire coating production line is quite long and occupies a large volume. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a production line for coating electronic detonator electronic ignition elements that occupies a small area and can be coated multiple times.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an electronic detonator electronic ignition element coating production line, comprising a feeding device, a multiple coating device, and a coating device arranged sequentially. The multiple coating device includes a frame, on which are provided a first rotary conveyor, a second rotary conveyor, a return conveyor mechanism, a first drying conveyor mechanism, a second drying conveyor mechanism, a coating mechanism, a coating storage mechanism, and a first robotic arm. The first rotary conveyor, the return conveyor mechanism, and the second rotary conveyor are arranged sequentially along a first direction. The first drying conveyor mechanism and the second drying conveyor mechanism are located on the same side of the frame, and their conveying directions are both along a second direction perpendicular to the first direction. The first drying conveyor mechanism is used to dock with the first rotary conveyor, and the second drying conveyor mechanism is used to dock with the second rotary conveyor. The first robotic arm is arranged corresponding to the first rotary conveyor and is used to transfer the electronic detonator electronic ignition element on the first rotary conveyor to the coating mechanism and transfer the electronic detonator electronic ignition element on the coating mechanism back to the first rotary conveyor.

[0005] The beneficial effects of this invention are as follows: In this electronic detonator electronic ignition element coating production line, the multi-coating equipment allows users to perform one, two, or even more coating operations on the electronic detonator electronic ignition element according to actual needs (that is, no matter how many times coating is required, only one multi-coating equipment can be set up), which has great flexibility, can effectively reduce the number of coating equipment in the production line, and is conducive to reducing the overall length of the coating production line, reducing the space occupied by the coating production line, and saving equipment purchase costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Example 1

[0031] Please refer to Figures 1 to 11 Embodiment 1 of the present invention is as follows: Figure 1 As shown, the electronic detonator electronic ignition element coating production line includes a feeding device 1, a multiple coating device 2, a coating device 3, and a sleeve installation device 4 arranged sequentially. In this embodiment, adjacent pairs of the feeding device 1, multiple coating device 2, coating device 3, and sleeve installation device 4 are indirectly connected via a connecting conveyor table 5. This allows for the installation of partition walls between adjacent pairs, thereby improving production safety. In other embodiments, to further shorten the overall length of the coating production line, adjacent pairs of the feeding device 1, multiple coating device 2, coating device 3, and sleeve installation device 4 can be directly connected. It should be noted that in other embodiments, the electronic detonator electronic ignition element coating production line may not include the sleeve installation device 4.

[0032] like Figure 2 and Figure 3As shown, the feeding device 1 includes a main body 11 and a feeding mechanism 12. The main body 11 is provided with a feeding rotary table 13, a feeding mechanism 141, a cutting mechanism 142, a detection mechanism 143 and a discharging mechanism 144. The feeding mechanism 141, the cutting mechanism 142, the detection mechanism 143 and the discharging mechanism 144 are arranged sequentially around the circumference of the feeding rotary table 13. Multiple mounting seats 131 are installed at equal intervals along the edge of the feeding rotary table 13. The feeding rotary table 13 is rotatable relative to the main body 11. The feeding mechanism 141 includes a feeding robot, which is used to pick up and place the electronic detonator electronic ignition element from the feeding mechanism 12 onto a mounting base 131 of the feeding rotary table 13; the cutting mechanism 142 is used to cut off the frame of the electronic detonator electronic ignition element carried by the mounting base 131 when it is rotated to its cutting position; the detection mechanism 143 includes a continuity testing mechanism and a first appearance inspection component, which is used to test the continuity of the electronic detonator electronic ignition element and the first appearance inspection component is used to inspect the appearance of the electronic detonator electronic ignition element; the unloading mechanism 144 includes an unloading robot, which is used to remove the qualified electronic detonator electronic ignition element carried by the mounting base 131 when it is rotated to its picking position; the main body 11 is also provided with a feeding rotary drive motor, which drives and connects to the feeding rotary table 13. The feeding rotary table 13, cutting mechanism 142 and testing mechanism 143 are commonly used mechanisms in the industry. For example, the Chinese utility model application with application number 202220499764.X discloses the corresponding mechanism.

[0033] The feeding mechanism 12 can be connected to or not connected to the main body 11. In this embodiment, the feeding mechanism 12 includes a tray transfer robot, a loaded tray storage bin, and an empty tray storage bin. The tray transfer robot is used to transfer the tray containing electronic detonators and electronic ignition elements located at the top of the loaded tray storage bin to the top of the empty tray storage bin. After the feeding mechanism 141 removes all the electronic detonators and electronic ignition elements from the tray located at the top of the empty tray storage bin, the empty tray storage bin operates to collect the tray at the top, from which the electronic detonators and electronic ignition elements have been removed, into the empty tray storage bin.

[0034] For cost and transportation convenience, the material tray is generally a blister tray. The electronic detonator and electronic ignition element have a certain degree of mobility within the cavity of the blister tray. To ensure processing quality, it is best to accurately position the electronic detonator and electronic ignition element before transferring it from the material tray to the mounting base 131. Therefore, in this embodiment, the feeding device 1 also includes a fixing structure. A positioning mechanism 132 is provided above the feeding rotary table 13. The positioning mechanism 132 is used to accurately position the electronic detonator and electronic ignition element. The feeding rotary table 13 has a through hole in its center. The fixed structure corresponds to the perforation setting. The fixed structure is fixedly set relative to the body 11. Optionally, the fixed structure is connected and fixed to the body 11. The positioning mechanism 132 is fixedly connected to the fixed structure. The positioning mechanism 132 can be a clamping positioning structure commonly used in the industry. After adding the positioning mechanism 132, the feeding mechanism 141 is used to pick up and place the electronic detonator electronic ignition element in the feeding mechanism 12 onto the positioning mechanism 132, and place the electronic detonator electronic ignition element located on the positioning mechanism 132 onto a mounting base 131 of the feeding rotary table 13.

[0035] Specifically, the main body 11 is also provided with a hollow indexing plate. The feeding rotation drive motor is connected to the feeding rotary table 13 through the hollow indexing plate. The fixing structure is a fixed shaft. One end of the fixed shaft extends into the hollow area of ​​the hollow indexing plate and is connected and fixed to the positioning mechanism 132.

[0036] It should be noted that in other embodiments, the positioning mechanism 132 may also be located on the main body 11. However, placing the positioning mechanism 132 above the loading rotary table 13 allows for a more reasonable arrangement of the components on the main body 11, avoiding an increase in the area occupied by the main body 11 due to the addition of the positioning mechanism 132, and ensuring that the loading equipment 1 can remain miniaturized.

[0037] like Figure 2 As shown, the feeding device 1 further includes a replacement mechanism 151 and a good product carrier platform 152 disposed on the main body 11. Along the circumferential direction of the feeding rotary table 13, the replacement mechanism 151 is located between the detection mechanism 143 and the discharge mechanism 144. The good product carrier platform 152 is used to place the good electronic detonator electronic ignition element to be replaced. The replacement mechanism 151 is used to replace the electronic detonator electronic ignition element on the feeding rotary table 13 that has been determined to be defective by the detection mechanism 143 with the good electronic detonator electronic ignition element. The replacement mechanism 151 includes a replacement robot arm.

[0038] Optionally, a recycling box 153 is also placed on the rack 21. The recycling box 153 is located near the good product carrier 152. The recycling box 153 is used to collect defective electronic detonator electronic ignition elements rejected by the replacement mechanism 151.

[0039] Please combine Figure 2 and Figure 4 The main body 11 is also provided with a feeding rotary conveyor 16, which is connected to the multiple-dip drug-coating device 2. The feeding device 1 also includes a carrier feeding assembly located on one side of the main body 11. The carrier feeding assembly is used to transport an empty carrier to the feeding rotary conveyor 16. The discharging mechanism 144 is used to pick up the electronic detonator electronic ignition element flowing through the detection station of the detection mechanism 143 on the feeding rotary table 13 and place it into the carrier on the feeding rotary conveyor 16. That is, the discharging mechanism 144 can transfer the qualified and replaced electronic detonator electronic ignition element on the mounting base 131 to the carrier carried by the feeding rotary conveyor 16.

[0040] The rotating conveyor 16 includes a fixed frame 161, a rotary drive 162, a rotating frame 163, a first linear conveying mechanism 164, a lifting mechanism 165, a stop assembly 166, and a stop block 167. The rotary drive 162 is located below the rotating frame 163 and connects the fixed frame 161 and the rotating frame 163. The rotating frame 163 includes a main frame and two oppositely arranged side frames, with the main frame connected to the side frames. The first linear conveying mechanism 164 is mounted on the rotating frame 163, and the conveying path of the first linear conveying mechanism 164 connects to the rotating frame 163. At least one end of the rotating frame 163; the lifting mechanism 165 includes a lifting drive 1651 and a lifting plate 1652, the lifting drive 1651 connects the lifting plate 1652 to the main frame, the lifting plate 1652 is located above the main frame and is set corresponding to the gap between the two side frames, optionally, the lifting plate 1652 is provided with a positioning post 1653 for positioning and cooperating with the positioning hole on the carrier; the main frame is provided with the stop assembly 166, the stop assembly 166 includes a stop drive provided near the end of the rotating frame 163. The rotary drive 162 can be a motor, etc.; the lifting drive 1651 and the stop drive can be cylinders, hydraulic cylinders, electric push rods, etc., respectively; the first linear conveying mechanism 164 can be a belt conveying mechanism, chain conveying mechanism, etc. In this embodiment, the first linear conveying mechanism 164 includes a conveying motor, a synchronizing rod and two sets of belt assemblies. The synchronizing rod is provided with meshing gears for cooperating with the belt assemblies. The conveying motor drives the synchronizing rod to rotate so as to drive the two sets of belt assemblies to move synchronously. The two sets of belt assemblies are respectively set on the two side frames, and the conveying motor is set on the main frame.

[0041] Optionally, the conveying path of the first linear conveying mechanism 164 connects the two ends of the rotating frame 163. In this embodiment, the side frame is provided with the stop block 167, which is located above the conveying path. When the lifting drive 1651 lifts the lifting plate 1652, the carrier on the first linear conveying mechanism 164 is lifted, so that the top surface of the lifting plate 1652 abuts against the stop block 167, thereby locking the relative position of the carrier on the lifting plate 1652 with the loading rotary conveyor table 16, so as to accurately pick up and put in the electronic detonator electronic ignition element.

[0042] like Figure 2 As shown, optionally, the main body 11 is also provided with a discharge conveying mechanism 17. The discharge conveying mechanism 17 is located on the side of the loading rotary conveyor 16 away from the loading rotary conveyor 13. The discharge conveying mechanism 17 is used to connect the loading rotary conveyor 16 with the lower station (i.e., the multiple-dip medicine equipment 2 or the connecting conveyor 5).

[0043] like Figure 5 As shown, the multiple-dip medicine application device 2 includes a frame 21, on which are mounted a first rotary conveyor 221, a second rotary conveyor 222, a return conveyor mechanism 223, a first drying conveyor mechanism 224, a second drying conveyor mechanism 225, a medicine application mechanism 226, a medicine storage mechanism 23, and a first robotic arm 241. The first rotary conveyor 221, the return conveyor mechanism 223, and the second rotary conveyor 222 are arranged sequentially along a first direction (i.e., the X-axis direction). The first drying conveyor mechanism 224 and the second drying conveyor mechanism 225 are located on the same side of the frame 21 and both... The conveying direction is along a second direction perpendicular to the first direction. The first drying conveying mechanism 224 is used to dock with the first rotary conveyor 221, and the second drying conveying mechanism 225 is used to dock with the second rotary conveyor 222. The first robot arm 241 is set corresponding to the first rotary conveyor 221. The first robot arm 241 is used to transfer the electronic detonator electronic ignition element on the first rotary conveyor 221 to the drug-coating mechanism 226 and transfer the electronic detonator electronic ignition element on the drug-coating mechanism 226 back to the first rotary conveyor 221.

[0044] The structure of the first rotary conveyor 221 can be the same as that of the loading rotary conveyor 16. Similarly, the structure of the second rotary conveyor 222 can be the same as that of the loading rotary conveyor 16. The medicine storage mechanism 23 is used to store medicine / moisture-proof paint; the medicine application mechanism 226 is used to drive the electronic detonator electronic ignition element fixed thereto to be applied medicine in the medicine storage mechanism 23 and then reset; the return conveying mechanism 223 is used to send the electronic detonator electronic ignition element on the second rotary conveyor 222 back to the first rotary conveyor 221; the first drying conveying mechanism 224 is used to send the electronic detonator electronic ignition element on the first rotary conveyor 221 into the drying device 27; the second drying conveying mechanism 225 is used to send the electronic detonator electronic ignition element that has completed the drying operation in the drying device 27 back to the second rotary conveyor 222.

[0045] Optionally, the multiple-dip medication device 2 further includes a feeding conveyor 227 and a discharging conveyor 228 mounted on the frame 21. The feeding conveyor 227 is used to connect with the first rotary conveyor 221, which is located between the feeding conveyor 227 and the return conveyor 223. The feeding conveyor 227 is configured to convey in a first direction. The discharging conveyor 228 is used to connect with the second rotary conveyor 222, which is located between the discharging conveyor 228 and the return conveyor 223. The discharging conveyor 228 is configured to convey in a first direction. It should be noted that the feeding conveyor 227 and the discharging conveyor 228 can be mounted on external mechanisms, meaning that the feeding conveyor 227 and the discharging conveyor 228 may not be part of the multiple-dip medication device 2.

[0046] In a preferred embodiment, the multiple-dip device 2 further includes a second robotic arm 242 mounted on the frame 21. The second robotic arm 242 is equipped with a second visual inspection component. This component is used to visually inspect the electronic detonator and electronic ignition element carried by the second rotary conveyor 222. The robotic arm 242 is used to remove any electronic detonator and electronic ignition element deemed defective by the second visual inspection component from the second rotary conveyor 222. The second visual inspection component includes a CCD camera, etc.

[0047] The frame 21 is also provided with a first defective material replacement area 25, which is used to place qualified electronic detonator electronic ignition elements. The second robotic arm 242 fills the gaps left after the defective electronic detonator electronic ignition elements on the second rotary conveyor table 222 are removed by picking up the electronic detonator electronic ignition elements in the first defective material replacement area 25. In this embodiment, the first defective material replacement area 25 is located on the side of the second rotary conveyor table 222 away from the second drying conveyor mechanism 225.

[0048] In this embodiment, the first defective material replacement area 25 is equipped with a first support tray. The first support tray is used to hold the electronic detonator electronic ignition elements that meet the appearance requirements, as well as the defective electronic detonator electronic ignition elements that have been rejected by the second robotic arm 242. This not only enables the replacement of defective electronic detonator electronic ignition elements, but also facilitates the collection of defective electronic detonator electronic ignition elements.

[0049] Once all the good quality electronic detonator electronic ignition elements carried by the first carrier plate have been replaced, the staff can simply replace the first carrier plate with a new one that carries the good quality electronic detonator electronic ignition elements.

[0050] Please combine Figure 5 and Figure 6 The drug storage mechanism 23 includes a drug storage pushing mechanism and a drug-coating tray 231. The drug-coating tray 231 has a receiving groove for holding gunpowder, moisture-proof paint, or other coatings. The drug storage pushing mechanism includes a drug storage drive structure 232, a mounting frame 233, a first drug storage lifting drive component 234, and a scraper 235 connected in sequence. The scraper 235 is located above the receiving groove and can extend into the receiving groove under the drive of the first drug storage lifting drive component 234. The scraper 235 can agitate the drug in the drug-coating tray 231 (Note: the drug mentioned here includes, but is not limited to, gunpowder, moisture-proof paint, etc.), accelerate the flow of the drug in the receiving groove, and ensure that the drug in the receiving groove remains flat before each application. This allows the drug-coating mechanism 226 to maintain the application effect while operating continuously, thereby improving the production yield. The drug-coating mechanism 226 can adopt an existing mechanism. The structure and operation process of the drug-coating mechanism 226, as well as the specific implementation method of the continuous operation of the drug-coating mechanism 226 for drug coating, can be referred to the technical solution disclosed in Chinese Utility Model Patent Application No. 202220494371.X, which will not be elaborated here.

[0051] Preferably, the drug storage pushing mechanism further includes a second drug storage lifting drive 236 and a disturbance plate 237. The second drug storage lifting drive 236 connects the disturbance plate 237 to the mounting bracket 233. The disturbance plate 237 has a slotted structure and is located above the receiving groove. Under the drive of the second drug storage lifting drive 236, the disturbance plate 237 can extend into the receiving groove. The disturbance plate 237 with the slotted structure can be a comb-tooth plate structure, a perforated plate structure, or other types of sheet material. The disturbance plate 237 can more effectively improve the drug deposition and stratification phenomenon in the receiving groove, which is beneficial to further improve the drug adhesion effect. Preferably, the disturbance plate 237 is parallel to the scraper 235.

[0052] like Figure 5 As shown, optionally, the multiple-dip medication device 2 also includes a medication storage mechanism 26. The medication storage mechanism 26 is connected to the receiving tank of the medication application tray 231 via a pump body. The medication storage mechanism 26 is used to store medication. Specifically, the medication storage mechanism 26 includes a medication storage tank and a stirring assembly. The medication storage tank is connected to the receiving tank via the pump body, and the stirring assembly is used to stir the medication stored in the medication storage tank to prevent medication sedimentation and stratification. The pump body can be a peristaltic pump, etc. The medication storage mechanism 26 can be mounted on the frame 21 or located away from the frame 21, depending on actual needs.

[0053] Please combine Figure 1 and Figures 7 to 9The multiple-drying equipment 2 further includes a drying device 27, which includes a machine base 271. A baffle plate 272 is provided on one side of the machine base 271. The baffle plate 272 has an inlet 2721 and an outlet 2722. The inlet 2721 connects to the first drying conveyor 224, and the outlet 2722 connects to the second drying conveyor 225. A placement platform 273 is provided at the bottom of the other side of the machine base 271. An air duct is provided inside the placement platform 273, and an air outlet 2731 communicating with the air duct is provided on the top surface of the placement platform 273. A drying box 274 is placed on the placement platform 273, and the lower part of the drying box 274 is connected to the air duct. The drying chamber 274 has a hot air inlet 2741 at the air vent 2731 and an air outlet 2742 at the top. Multiple windows 2743 are located on the side of the drying chamber 274 near the baffle 272, and the drying chamber 274 has placement positions for connecting to the windows 2743. A conveying device 275 is installed inside the machine platform 271. The conveying device 275 is used to transport the carrier carrying the electronic detonator electronic ignition element for the coating operation from the feed inlet 2721 to the placement position and to output the carrier located at the placement position from the discharge outlet 2722. A recessed area is formed between the placement platform 273 and the baffle 272 to accommodate part of the conveying device 275. This drying device 27 has the advantages of reasonable layout, compact structure, and small footprint. The baffle 272 not only improves the safety of the multiple coating equipment 2 but also reduces heat loss from the drying chamber 274 to a certain extent, thereby improving the heat utilization efficiency of the drying chamber 274.

[0054] Please combine Figure 5 , Figure 8 and Figure 9When the electronic detonator's electronic ignition element is conveyed along the first direction onto the first rotary conveyor 221, the first coating of the electronic detonator's electronic ignition element is completed through the cooperation of the first robotic arm 241, the coating mechanism 226, and the storage mechanism 23. Then, the coated electronic detonator's electronic ignition element is conveyed to the drying device 27 through the first robotic arm 241, the first rotary conveyor 221, and the first drying conveyor 224. After drying, the electronic detonator's electronic ignition element is sent back to the second rotary conveyor 222 by the second drying conveyor 225. If it does not need to be coated again, the second rotary conveyor 222 sends the electronic detonator's electronic ignition element out of the multiple coating device 2. If it needs to be coated again, the second rotary conveyor 222 sends the electronic detonator's electronic ignition element back to the first rotary conveyor 221 via the return conveyor 223. Then, the electronic detonator's electronic ignition element is coated again through the cooperation of the first robotic arm 241, the coating mechanism 226, and the storage mechanism 23. Therefore, the multiple coating equipment 2 can perform one, two, or even more coating operations on the electronic detonator electronic ignition element according to the user's needs, which greatly improves the flexibility of the coating equipment. One coating equipment can be used to perform one or more coating operations on the electronic detonator electronic ignition element as needed, which is conducive to reducing the overall length of the production line, reducing the area occupied by the production line, and saving equipment purchase costs.

[0055] like Figure 9 As shown, preferably, the drying chamber 274 has multiple placement positions, arranged in an array. One end of the machine base 271 is provided with a control console 276. Preferably, the control console 276 contains a hot air blower connected to the air duct, which further saves space.

[0056] Please combine Figure 8 and Figure 10The conveying device 275 includes an XZ two-axis motion platform 2751. The output end of the XZ two-axis motion platform 2751 is connected to a two-stage conveying mechanism 2752. The conveying direction of the two-stage conveying mechanism 2752 is set along the second direction (i.e., the Y-axis direction). The two-stage conveying mechanism 2752 includes a frame 27521 connected to the XZ two-axis motion platform 2751. The frame 27521 is equipped with a chain conveying assembly 27522 and a hook conveying assembly 27523. The chain conveying assembly 27522 is used to receive the carrier from the feed port 2721 and to transport the carrier out of the discharge port 2722. The hook conveying assembly 27523 includes a connected linear drive and a bracket. The bracket is equipped with a locking post, which is used to cooperate with the positioning hole on the carrier. The hook conveying assembly 27523 is used to push the carrier on the chain conveying assembly 27522 into the placement position and hook the carrier located in the placement position onto the chain conveying assembly 27522.

[0057] In some embodiments, the coating device 3 can be an existing coating device. In this embodiment, the structure of the coating device is the same as that of the above-mentioned multiple coating device 2. Therefore, in the process flow of this production line, the number of times the electronic detonator electronic ignition element is coated can also be adjusted according to actual needs without adding extra equipment. It can be a single coating or multiple coatings.

[0058] like Figure 11 As shown, the sleeve installation equipment 4 includes a main frame 41, on which a sleeve installation rotary table 42, a sleeve installation conveyor line 43, a sleeve installation loading robot 44, and a sleeve installation unloading robot 45 are provided. The sleeve installation unloading robot 45 is provided with a third appearance inspection component. The sleeve installation rotary table 42 is rotatable relative to the main frame 41. Multiple seats 421 are installed at equal intervals along the edge of the sleeve installation rotary table 42. The seats 421 are used to support the electronic detonator electronic ignition element. The seats 421 are sequentially located along the circumference of the sleeve installation rotary table 42, corresponding to the loading station 461, the sleeve installation station 462, the heat shrink sleeve station 463, the electrical testing station 464, and the appearance inspection and unloading station 465.

[0059] The sleeve installation and loading robot 44 is used to pick up and place the electronic detonator electronic ignition element from the sleeve installation conveyor line 43 onto the base 421 at the loading station 461; the electronic detonator electronic ignition element on the base 421 is sleeved by an external mechanism at the sleeve installation station; when the sleeved electronic detonator electronic ignition element is rotated to the heat shrink sleeve station 463, the sleeve shrinks under the action of a heat engine, thereby achieving a tight connection between the sleeve and the electronic detonator electronic ignition element; connection After the electronic detonator's electronic ignition element with a good sleeve is rotated to the electrical testing station 464, a continuity test is performed. Then, when the electronic detonator's electronic ignition element with the continuity test completed is rotated to the appearance inspection and unloading station 465, the third appearance inspection component on the installation and unloading robot performs an appearance inspection on the electronic detonator's electronic ignition element with the sleeve connected. Subsequently, the installation and unloading robot sends the qualified electronic detonator's electronic ignition element back to the sleeve installation conveyor line 43 and rejects the unqualified electronic detonator's electronic ignition element.

[0060] Optionally, the main frame 41 is further provided with a second defective material replacement area 47. The second defective material replacement area 47 is used to place qualified electronic detonator electronic ignition elements after the sleeve installation is completed. The sleeve installation unloading robot 45 fills the gap left after the defective electronic detonator electronic ignition elements on the sleeve installation conveyor line 43 are rejected by taking the electronic detonator electronic ignition elements in the second defective material replacement area 47.

[0061] In this embodiment, the second defective material replacement area 47 is equipped with a second support tray. This tray carries qualified electronic detonator ignition elements after sleeve installation, as well as defective electronic detonator ignition elements rejected by the sleeve installation unloading robot 45. This not only facilitates the replacement of defective electronic detonator ignition elements but also allows for their convenient collection. Once all the qualified electronic detonator ignition elements carried by the second support tray have been replaced, the operator simply replaces the tray with a new one carrying the qualified electronic detonator ignition elements.

[0062] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
