Description

Technical Field

[0001] This invention relates to the field of basic detonator charge detection technology, and in particular to a basic detonator charge detection device and method. Background Technology

[0002] In the basic detonator loading process of a mass detonation system, a metering plate is typically used for fixed-volume loading, simultaneously loading dozens of detonators at a time. If the metering plate becomes clogged or malfunctions, the charge amount for a particular detonator may not meet requirements. To ensure the quality of the detonator loading, it is necessary to accurately measure the charge amount for each layer of detonators, using grams as the unit of weight.

[0003] In existing technology, the current measurement method involves inserting a probe to measure the charge height into the detonator, and then using an optical fiber or laser displacement sensor to measure the height of the probe's upper surface. The charge content of the detonator is judged by whether this upper surface height is within a set range, primarily based on the height of the charge after loading. However, charge height and charge content are two different physical quantities. The conversion between them requires the use of the powder's pseudo-density, but the pseudo-density varies from batch to batch due to particle size variations. Furthermore, the amount of charge remaining in the container during loading also causes differences in the powder's pseudo-density, resulting in variations in the charge content and making it impossible to accurately measure the charge content.

[0004] Therefore, how to provide a device and method for detecting the charge of a basic detonator in order to accurately measure the charge amount in each basic detonator has become an urgent technical problem to be solved. Summary of the Invention

[0045] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] This invention discloses a charging detection device for a basic detonator 5, such as... Figure 1-19 As shown, it includes: a conveyor line 1, a weighing device 2, a loading device 3, and a height measuring device 4. A base detonator 5 is placed on a carrier 6. A first pushing assembly 7 and a pushing assembly 8 are installed on the conveyor line 1. The conveyor line 1 is used to transport the unloaded base detonator 5 and the base detonator 5 after height measurement. The charging device 3 is used to fill the base detonator 5 with powder. The height measuring device 4 is used to receive the base detonator 5 after charging and to measure the height of the powder in the base detonator 5. The number of weighing devices 2 is set to two. One weighing device 2 is located between the loading device 3 and the conveyor line 1, and is used to weigh the carrier 6 and the base detonator 5 to be loaded as a whole. The other weighing device 2 is located between the height measuring device 4 and the conveyor line 1, and is used to weigh the carrier 6 and the base detonator 5 after height measurement as a whole. The first pushing component 7 is used to push the basic detonator 5 to be filled sequentially onto one of the weighing devices 2 and the charging device 3, and the pushing component 8 is used to push the carrier 6 on another weighing device 2 and the measured basic detonator 5 onto the conveyor line 1.

[0047] It should be noted that the charging detection device for a basic detonator 5 disclosed in this embodiment of the invention uses one weighing device 2 to weigh the carrier 6 and the basic detonator 5 to be loaded as a whole, and another weighing device 2 to weigh the carrier 6 and the basic detonator 5 after height measurement as a whole. The height measurement device 4 measures the height of the powder inside the basic detonator 5. There is no need to measure and input false density data of the powder, which reduces manual operation steps and improves the convenience of use. The amount of charge in each basic detonator 5 can be accurately measured.

[0048] like Figure 1-5 As shown, it also includes a door sealing assembly 9. There are two door sealing assemblies 9. One door sealing assembly 9 is located between the loading device 3 and one of the weighing devices 2, and the other door sealing assembly 9 is located between the height measuring device 4 and the other weighing device 2. The door sealing assembly 9 is used to control the flow of materials. In this embodiment, the door sealing assembly 9 serves as a separator, separating the weighing device 2 from the loading device 3 and the height measuring device 4.

[0049] like Figure 5 As shown, the door sealing assembly 9 includes a door sealing plate 91, a movable door 92, and a door sealing cylinder 93. The door sealing plate 91 has an opening 911, and the door sealing cylinder 93 is used to drive the movable door 92 to move closer to or away from the opening 911.

[0050] like Figure 5 As shown, a door seal adapter plate 94 is installed at the opening 911, and the door seal adapter plate 94 has a notch 941 for accommodating the sliding passage of the movable door 92. It should be noted that the movable door 92 is driven to move closer to or away from the opening 911 by the door seal cylinder 93, and the carrier 6 on one of the weighing devices 2 is pushed to the notch 941 and the loading platform 34 of the loading device 3 by the first pushing assembly 7, so as to realize the loading of the basic detonator 5 to be filled.

[0051] like Figure 1-4 As shown, there are two conveyor lines 1, arranged in an upper and lower layer, and connected to the weighing device 2. It should be noted that, since the two conveyor lines 1 are arranged in an upper and lower layer, both conveyor lines 1 are used for transporting materials. The upper conveyor line 1 is used to transport the base detonators 5 to be filled and the base detonators 5 after loading and height measurement, transferring them to the next workstation; the lower conveyor line 1 is used to return the unloaded carrier 6.

[0052] like Figure 4 As shown, the conveyor line 1 includes a conveyor frame 11, a conveyor belt 12, and a conveyor motor. The conveyor motor drives the conveyor belt 12 to move on the conveyor frame 11. It should be noted that the conveyor motor drives the conveyor belt 12 to move on the conveyor frame 11, thereby enabling the processing and transfer of materials.

[0053] like Figure 4 As shown, the first pushing assembly 7 includes a first pushing cylinder 71 and a first pushing plate 72. The pushing direction of the first pushing cylinder 71 is perpendicular to the conveying direction of the conveyor line 1. The first pushing cylinder 71 is installed on the conveyor line 1 and is used to drive the first pushing plate 72 to move linearly. In the specific implementation process, the first pushing cylinder 71 drives the first pushing plate 72 to move linearly. Since the pushing direction of the first pushing cylinder 71 is perpendicular to the conveying direction of the conveyor line 1, the first pushing plate 72 first pushes the carrier 6 loaded with several basic detonators 5 to be filled onto one of the weighing devices 2 to achieve overall weighing before loading; then the carrier 6 is further pushed onto the door seal adapter plate 94 and the loading platform 34, so that the basic detonators 5 can proceed to the next loading operation.

[0054] like Figure 1-4 As shown, a baffle 73 is installed on one side of the first pushing cylinder 71 on the conveyor line 1, and a first detection sensor 74 is installed on the baffle 73. It should be noted that the baffle 73 acts as a block, keeping the carrier 6 in the first pushing position; the first detection sensor 74 detects the carrier 6, and when the carrier 6 is detected, the first pushing assembly 7 is activated, pushing the carrier 6 onto one of the weighing devices 2.

[0055] like Figure 1-4 As shown, the material feeding assembly 8 includes a material feeding base plate 81 installed on the conveyor line 1. A first material feeding cylinder 82 is installed on the material feeding base plate 81. A second material feeding cylinder 83 is installed on the telescopic rod of the first material feeding cylinder 82. A material feeding plate 84 is installed on the telescopic rod of the second material feeding cylinder 83. The material feeding direction of the material feeding plate 84 is perpendicular to the conveying direction of the conveyor line 1. It should be noted that, driven by the first material feeding cylinder 82, the second material feeding cylinder 83 and the material feeding plate 84 are driven to telescopically move, thereby moving the carrier 6 on another weighing device 2 onto the conveyor line 1, allowing the basic detonator 5 after loading and testing to enter the next station.

[0056] like Figure 1-12 As shown, the loading device 3 includes a loading frame 31, a material leakage plate 32, and a loading assembly 33. A loading platform 34 is slidably connected to the loading frame 31. The material leakage plate 32 is installed on the loading frame 31 and has a material leakage hole 321. The loading frame 31 is equipped with a first lifting cylinder 35 for driving the loading platform 34 to move up and down in the vertical direction, so that the base detonator 5 on the carrier 6 is inserted into the leakage hole 321; The filling assembly 33 is used to fill a preset amount of powder into the base detonator 5 through the discharge hole 321. A second pushing assembly 36 is also installed on the filling frame 31, which pushes the filled base detonator 5 onto the height measuring device 4. It should be noted that the filling platform 34 is raised by the first lifting cylinder 35, and the base detonator 5 is inserted into the discharge hole 321. The filling assembly 33 then performs the filling function, filling a certain amount of powder into the base detonator 5 through the discharge hole 321.

[0057] like Figure 7-12 As shown, the filling assembly 33 includes a filling plate 331, a guide plate 332, and a filling funnel 333, which are sequentially located above the material leakage plate 32. The filling plate 331 has filling holes 3311 corresponding to the material leakage holes 321, and the guide plate 332 has guide holes 3321 that are staggered with the filling holes 3311. The drug loading frame 31 is provided with a first filling cylinder 334 for driving the filling plate 331 to move linearly. In this embodiment, the filling plate 331 is slidably connected to the drug loading frame 31.

[0058] It should be noted that in the initial state, since the guide hole 3321 and the filling hole 3311 are staggered, and the filling hole 3311 is connected to the discharge hole 321, the filling plate 331 is moved by the first filling cylinder 334, so that the filling hole 3311 is connected to the guide hole 3321 and the filling hole 3311 is staggered from the discharge hole 321, and the powder in the guide hole 3321 enters the filling hole 3311; then the filling plate 331 is moved back to its original position by the first filling cylinder 334, so that the filling hole 3311 is connected to the discharge hole 321 and the guide hole 3321 is staggered from the filling hole 3311, so that the powder in the filling hole 3311 falls into the base detonator 5, thereby realizing the filling of the powder.

[0059] like Figure 7-12 As shown, the loading frame 31 is equipped with a second loading cylinder 335 for driving the guide plate 332 to move linearly. In specific implementation, the guide plate 332 is slidably connected to the loading frame 31. The second loading cylinder 335 drives the guide plate 332 to move, so that the guide hole 3321, the loading hole 3311 and the discharge hole 321 are all connected, which can discharge the residual powder in the loading funnel 333 and achieve the cleaning of the loading device 3.

[0060] like Figure 12 As shown, a guide slope is provided inside the guide hole 3321. It should be noted that the guide slope allows the powder to be discharged smoothly, preventing excess powder from being stored in the guide hole 3321.

[0061] like Figure 12As shown, the filling hole 3311 has a rectangular cross-section, and the discharge hole 321 includes a first section, a second section, and a third section that are sequentially arranged from top to bottom. The first and third sections have trapezoidal cross-sections, while the second section has a rectangular cross-section. It should be noted that because the first and third sections have trapezoidal cross-sections, the powder can smoothly enter the discharge hole 321 and the base detonator 5.

[0062] like Figure 7-10 As shown, a first clamping assembly 37 for clamping the carrier 6 is installed on the loading platform 34. It should be noted that the first clamping assembly 37 clamps the carrier 6 to prevent the carrier 6 from shifting when the first lifting cylinder 35 drives the loading platform 34 to move up and down, thus ensuring the smooth loading operation of the loading device 3.

[0063] like Figure 10 As shown, the first clamping assembly 37 includes a first clamping rod 371 and a first clamping cylinder 372 installed at the bottom of the loading platform 34. The first clamping cylinder 372 is used to drive the first clamping rod 371 to move so that the first clamping rod 371 clamps the carrier 6 on the loading platform 34. In specific implementation, the first clamping rod 371 is L-shaped. The first clamping cylinder 372 drives the first clamping rod 371 to perform telescopic and rotational movements, which can clamp or unlock the carrier 6. When the carrier 6 is in the lifting and lowering movement, the first clamping assembly 37 clamps the carrier 6. After the carrier 6 is loaded with explosives, the first clamping assembly 37 unlocks the carrier 6, and the second pushing assembly 36 pushes the carrier 6 onto the moving platform 432 so that the loaded basic detonator 5 can proceed to the next loading and height measurement operation.

[0064] like Figure 7 , Figure 11 and Figure 12 As shown, the second pushing assembly 36 includes a second pushing plate 361 and a second pushing cylinder 362 mounted on the loading frame 31. The second pushing cylinder 362 is used to push the carrier 6 on the loading platform 34. It should be noted that the second pushing cylinder 362 pushes the second pushing plate 361 to move linearly, pushing the carrier 6 onto the moving platform 432, so that the loaded base detonator 5 can proceed to the next step of loading and height measurement.

[0065] like Figure 10 As shown, a second detection sensor 38 is installed on the loading platform 34. It should be noted that the second detection sensor 38 serves a detection function, capable of detecting whether there is a carrier 6 on the loading platform 34.

[0066] like Figure 8 , Figure 9 and Figure 12As shown, a transition plate 336 located on the loading frame 31 is installed between the loading plate 331 and the discharge plate 32. The transition plate 336 has a transition hole 3361, which is connected to both the loading hole 3311 and the discharge hole 321. The transition plate 336 is also connected to the loading funnel 333. It should be noted that the transition hole 3361, which is connected to both the loading hole 3311 and the discharge hole 321, ensures the smooth discharge of the powder.

[0067] like Figure 1-19 As shown, the height measuring device 4 includes a height measuring frame 41, a lifting plate 421, a moving component 43, and a detection component 44; A height-measuring probe 451 is attached to the lifting plate 421 and passes through it. A second lifting cylinder 452 is installed on the height-measuring frame 41 to drive the lifting plate 421 to move vertically. A moving component 43 is used to receive the carrier 6 on the charging device 3 and move it to the height-measuring position. A detection component 44 is used to measure the height of the height-measuring probe 451 inserted into the base detonator 5. A third pushing component 47 is installed on the height-measuring frame 41 to push the measured base detonator 5 onto another weighing device 2. The end face of the height-measuring probe 451 that is inserted into the base detonator 5 is flat.

[0068] In the specific implementation process, the height of the bottom surface of the unloaded base detonator 5 is a preset value. After filling with powder, the height probe 451 is inserted into the base detonator 5. The detection component 44 measures the height of the height probe 451 inserted into the base detonator 5, and the height of the powder in the base detonator 5 can be calculated.

[0069] like Figure 13-18 As shown, the detection component 44 includes a laser profiler 441 located above the height-measuring probe 451. The laser profiler 441 is used to detect the height position of the height-measuring probe 451. In this embodiment, the laser profiler 441 performs the detection function, detecting the height position of the height-measuring probe 451.

[0070] like Figure 13-18 As shown, the detection assembly 44 also includes a detection motor 442. The laser profiler 441 is slidably connected to the height measuring frame 41. The detection motor 442 is used to drive the laser profiler 441 to move linearly in the horizontal direction. It should be noted that by driving the laser profiler 441 to move linearly in the horizontal direction through the detection motor 442, the laser profiler 441 can detect the height of the height measuring probe 451 on the lifting plate 421.

[0071] like Figure 13As shown, the moving component 43 includes a linear moving module 431 and a moving stage 432. The linear moving module 431 is used to drive the moving stage 432 to move linearly. It should be noted that the linear moving module 431 drives the moving stage 432 to move linearly, which can drive the moving stage 432 to the receiving position to receive the loaded basic detonator 5 and move it to the height measuring position for height measurement.

[0072] like Figure 16 As shown, a second clamping assembly 48 is installed on the moving table 432. The second clamping assembly 48 is used to clamp the carrier 6 onto the moving table 432. It should be noted that the second clamping assembly 48 performs a clamping function, clamping the carrier 6 tightly onto the moving table 432 to prevent the carrier 6 from shifting when the moving table 432 moves, thus ensuring the stability of material transfer.

[0073] like Figure 16 As shown, the second clamping assembly 48 includes a second clamping cylinder 481 and a second clamping block 482. The second clamping cylinder 481 is installed at the bottom of the moving platform 432 and is used to drive the second clamping block 482 to perform telescopic movement. It should be noted that by driving the second clamping block 482 closer to the carrier 6 through the second clamping cylinder 481, the carrier 6 can be clamped onto the moving platform 432.

[0074] like Figure 16 As shown, the second clamping block 482 is provided with a V-shaped clamping groove 4821. The moving stage 432 is provided with a V-shaped opening corresponding to the clamping groove 4821. It should be noted that, because the clamping groove 4821 is V-shaped, the second clamping block 482 is in closer contact with the carrier 6.

[0075] like Figure 13 As shown, a third detection sensor 411 and a fourth detection sensor 412 are installed on the height measuring frame 41. The third detection sensor 411 is used to detect the carrier 6 on the docking material position, and the fourth detection sensor 412 is used to detect the carrier 6 on the height measuring position.

[0076] like Figure 15 and Figure 17 As shown, a spring 46 is sleeved on the height measuring probe 451, and the spring 46 abuts against the lifting plate 421. It should be noted that the spring 46 acts as a buffer, allowing the height measuring probe 451 to insert into the base detonator 5 and make flexible contact with the powder, preventing excessive impact force from the height measuring probe 451.

[0077] like Figure 15 and Figure 17 As shown, a first positioning plate 422 is slidably connected to the lifting plate 421, and the first positioning plate 422 is provided with a first positioning hole 4221 for accommodating the height measuring probe 451 through which it passes.

[0078] like Figure 15 and Figure 17 As shown, a second positioning plate 423 is mounted on the first positioning plate 422. The second positioning plate 423 has a second positioning hole 4231 corresponding to the first positioning hole 4221. A positioning tube 424 is installed within both the first and second positioning holes 4221, and the positioning tube 424 is used to accommodate the height measuring probe 451 through which it passes. In practice, both the first positioning plate 422 and the second positioning plate 423 are movably connected to the lifting plate 421 via a lifting rod 425.

[0079] It should be noted that when the second lifting cylinder 452 drives the lifting plate 421 to descend, it simultaneously drives the height measuring probe 451, the first positioning plate 422, the second positioning plate 423, and the positioning tube 424 to descend. One end of the base detonator 5 abuts against the positioning tube 424, the height measuring probe 451 passes through the positioning tube 424 and comes into contact with the powder inside the base detonator 5, and the laser profiler 441 detects the height position of the height measuring probe 451.

[0080] like Figure 15 and Figure 17 As shown, a discharge channel 413 is installed on the height measuring frame 41. The third pushing assembly 47 includes a third pushing cylinder 471 and a third pushing plate 472. The third pushing cylinder 471 drives the third pushing plate 472 to move linearly, pushing the carrier 6 on the moving platform 432 to the discharge channel 413 for discharge. It should be noted that after the height of the base detonator 5 is measured, the third pushing cylinder 471 drives the third pushing plate 472 to move linearly, pushing the carrier 6 on the moving platform 432 to the discharge channel 413 for discharge, and then pushing it to another weighing device 2 for weighing.

[0081] In the specific implementation process, as shown in the figure, the weighing device 2 includes a weighing frame 21 and an electronic weighing scale 22 located on the weighing frame 21. A receiving platform 23 is slidably connected to the weighing frame 21, and a third lifting cylinder 24 is installed on the weighing frame 21 to drive the receiving platform 23 to move vertically. The weighing frame 21 is connected to the conveyor line 1. When the receiving platform 23 receives the carrier 6, the third lifting cylinder 24 drives the receiving platform 23 to descend, moving the carrier 6 onto the electronic weighing scale 22 for weighing. The receiving platform 23 has through holes corresponding to the electronic weighing scale 22.

[0082] It should be noted that a fourth lifting cylinder 25 is installed on the weighing frame 21. A blocking block 26 is connected to the telescopic rod of the fourth lifting cylinder 25. The blocking block 26 is used to restrict the movement of the carrier 6, so as to ensure that after the receiving platform 23 is lowered, the carrier 6 can move smoothly on the electronic weighing scale 22 for weighing.

[0083] According to a second aspect, embodiments of the present invention disclose a method for detecting the charge of a basic detonator 5, such as... Figure 20 As shown, it includes the following steps: Step S10: Weigh several basic detonators 5 to be loaded and their carriers 6 as a whole using one of the weighing devices 2 to obtain the initial weight before loading; the height of the inner bottom surface of the basic detonator 5 to be loaded is a preset value. Step S20: Fill the base detonator 5 with the powder using the charging device 3; Step S30: The height of the explosive charge inside the base detonator 5 is measured by the height measuring device 4 after the charge is loaded. Step S40: Calculate the volume of the explosive charge in each basic detonator 5 based on its preset height, charge height, and internal shape. In this embodiment, the internal shape of the basic detonator 5 can be regular or irregular. For the volume of an irregular container, an integral method or experimental method can be used; for the volume of a regular container, a volume formula can be used for calculation. Step S50: Weigh the base detonator 5 and its carrier 6 after loading the explosive using another weighing device 2 to obtain the total weight of the explosive after loading. Step S60: Calculate the charge weight of each basic detonator 5 based on the initial weight, the total charge weight, and the charge powder volume of each basic detonator 5.

[0084] It should be noted that the method for detecting the charge of a basic detonator 5 disclosed in this embodiment of the invention involves using one weighing device 2 to weigh the carrier 6 and the basic detonator 5 to be filled as a whole, and another weighing device 2 to weigh the carrier 6 and the basic detonator 5 after height measurement as a whole. The height measurement device 4 measures the height of the powder inside the basic detonator 5. Based on the initial weight, the total weight of the charge, and the volume of the powder in each basic detonator 5, the charge weight of each basic detonator 5 is calculated. This invention eliminates the need to measure and input false density data of the powder, reduces manual operation steps, improves ease of use, and can accurately measure the charge content in each basic detonator 5.

[0085] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
