A loading mold 4 and a transfer mold 6 for accommodating basic detonators 8 are transported inside the transport rack 7;

[0063] Specifically:

[0064] The rotation detection device 1 includes a loading mold feeding part 11 for accommodating the loading mold 4 and a loading mold discharging part 12. A first turntable 15 is installed between the loading mold feeding part 11 and the loading mold discharging part 12. The first turntable 15 is driven to rotate by a motor arranged at its bottom. Loading seats for accommodating the loading mold 4 are arranged in an annular array at the edge of the first turntable 15. Drug height detection devices 16 adapted to the loading mold 4 are arranged at intervals along the rotation direction of the loading seats at the upper end of the first turntable 15. A visual detection device 14 is arranged at the upper end of the loading mold feeding part 11, and a lifting device 13 for controlling the lifting of the loading mold feeding part 11 is arranged at the lower end. At the upper end of the loading mold discharging part 12, there is a discharging device 17 for pulling the loading mold 4 in the first turntable 15 into the loading mold discharging part 12, which is controlled by a cylinder in the discharging device 17;

[0065] The tube-withdrawing and floating medicine device 2 comprises a floating medicine mold material platform 21 and a tube-withdrawing and floating medicine workbench 22. The floating medicine mold material platform 21 is arranged on one side of the tube-withdrawing and floating medicine workbench 22 and is connected thereto. The tube-withdrawing and floating medicine workbench 22 comprises a second turntable 226, an empty tube filling mold discharge portion 221 for accommodating the filling mold 4, a full tube filling mold feed portion 222, and an empty tube intermediate transfer mold feed portion 223 and a full tube intermediate transfer mold discharge portion 224 for accommodating the intermediate transfer mold 6. A charging seat for accommodating the filling mold 4 is arranged in a circular array at the edge of the second turntable 226. A motor for controlling its rotation is arranged at the lower end of the second turntable 226. The outlets of the second turntable 226 along the rotation direction of the charging seat correspond to the full tube filling mold feed part 222, the tube withdrawal device 227 and the empty tube filling mold discharge part 221, respectively, so that the filling mold 4 in the full tube filling mold feed part 222, the tube withdrawal device 227 and the empty tube filling mold discharge part 221 can enter and exit the second turntable 226. The second turntable 226 pushes the loading mold 4 in its loading seat to move to the tube withdrawing device 227 or the lifting and turning device 229 through the loading mold pushing device 225. The upper end of the tube withdrawing device 227 is movably installed with a tube collecting device 228 for grabbing and transporting the basic detonator 8. The tube collecting device 228 transports the basic detonator 8 to the upper end of the receiving device 2212. The receiving device 2212 is driven by the cylinder on the loading mold pushing device 225. After receiving the basic detonator 8, the floating medicine mold 5 moves it to the lower end of the tube pressing device 2210. The tube pressing device 2210 squeezes the basic detonator 8 in the receiving device 2212 from the wiping floating medicine mold 5 into the intermediate transfer mold 6. In the process of the basic detonator 8 passing through the wiping floating medicine mold 5, the silicone layer 52 and the sponge layer 54 in the wiping floating medicine mold 5 wipe the tube wall to complete the wiping floating medicine step. The grabbing and transporting device 2211 takes the intermediate transfer mold 6 out to the transport rack 7 for transportation;

[0066] The scrap rejection device 3 includes a transfer mold feed part 31 and a transfer mold discharge part 32 for accommodating the transfer mold 6. A scrap write-off oil pan 33 is arranged between the transfer mold feed part 31 and the transfer mold discharge part 32.

[0068] The loading die 4 is provided with loading die material placement holes 41 for installing the base detonator 8 at intervals. A limit sealing ring 42 that has an interference fit with the side wall of the base detonator 8 is arranged in the loading die material placement hole 41 to prevent the base detonator 8 from falling out of the loading die material placement hole 41. The transfer die 6 is provided with a transfer die material placement hole 61 for installing the base detonator 8. A limit hole 62 is arranged at the lower end of the transfer die material placement hole 61, and the aperture of the limit hole 62 is smaller than that of the transfer die material placement hole 61 to prevent the base detonator 8 from falling out of the transfer die 6. The floating drug wiping die 5 is provided with through holes for the base detonator 8 to pass through at intervals. The floating drug wiping die 5 is composed of an upper die 51, a silica gel layer 52, a middle plate 53, a sponge layer 54, and a lower die 55 combined in sequence from top to bottom. The aperture of the through holes arranged in the silica gel layer 52 and the middle plate 53 is slightly smaller than the aperture of the through holes arranged in the upper die 51, the middle plate 53, and the lower die 55, so that the silica gel layer 52 and the sponge layer 54 can achieve the effect of wiping the floating drug on the tube wall when the base detonator 8 passes through.

[0069] Embodiment 2:

[0070] As Figure 2 、 5 、6, and 7 show, as a preferred mode of the above embodiment, the loading die feeding part 11 is movably installed and its lifting is controlled by a lifting device 13 at the lower end. A positioning cylinder adapted to the loading die 4 is arranged on the end face of the loading die feeding part 11, and a pushing cylinder for pushing the loading die 4 into the loading seat of the first turntable 15 is arranged on one side of the loading die feeding part 11. By setting the lifting device 13 to control the lifting of the loading die feeding part 11 to cooperate with the vision detection device 14, the appearance of the nozzle and the strengthening cap of the base detonator 8 can be detected in batches. Through the setting of the positioning cylinder and the pushing cylinder, the rotation detection device 1 can move and position the loading die 4 more conveniently, further improving the detection effect of the device.

[0071] The medicine height detection device 16 includes a fixed downward pressure cylinder 161, whose output end faces downward and is fixed with a mounting box 162. The mounting box 162 is provided with induction heads 163 arranged at intervals. The lower end of the induction head 163 is movably provided with a probe 164 extending out of the lower end surface of the mounting box 162. The probe 164 corresponds to the position of the half of the filling mold material placement hole 41 in the filling mold 4. The medicine height detection device 16 is provided with two tube withdrawal and floating medicine devices. The probe 164 in the other medicine height detection device 16 corresponds to the position of the half of the filling mold material placement hole 41 in the filling mold 4. Specifically, when the downward pressure cylinder 161 drives the mounting box 162 to descend, the bottom of the probe 164 will penetrate into the basic detonator 8 to detect the medicine height in the basic detonator 8, and the top will be separated from the induction head 163. The induction head 163 is a proximity switch, which sends out the signal obtained, that is, the medicine height result detected, to complete the detection of the medicine height. By setting the downward pressure cylinder 161, the installation box 162, the sensor head 163, and the probe 164 to cooperate with the filling mold 4, the basic detonator 8 in the filling mold 4 is tested for the powder height, and the detection process is divided into two times, that is, multi-channel detection in batches, to further improve the detection effect of the device on the powder height of the basic detonator 8.

By setting the sliding lifting device 211, the floating medicine mold clamping device 212, and the movable platform 213 to cooperate with the receiving device 2212 in the withdrawing tube wiping floating medicine workbench 22, the floating medicine mold 5 can be automatically replaced to avoid the wiping effect of the floating medicine mold 5 being reduced after multiple wiping of floating medicine, and there is no need to frequently take it out for disassembly and cleaning, thereby improving the efficiency and effect of wiping floating medicine.

[0074] The tube withdrawing device 227 includes a placing table 2274 for accommodating the loading die 4. The placing table 2274 receives the loading die 4 from the second turntable 226. On one side of the placing table 2274, there is a pushing cylinder for pushing the loading die 4 back to the loading seat of the second turntable 226. At the lower end of the placing table 2274, there is a first ejector pin mounting plate 2272 driven by the output end of the electric cylinder 2271 to move up and down. At the upper end of the first ejector pin mounting plate 2272, first ejector pins 2273 are arranged at intervals corresponding to the positions of the loading die placing holes 41 in the loading die 4. That is, when the loading die 4 enters the placing table 2274 from the second turntable 226, the electric cylinder 2271 drives the first ejector pin mounting plate 2272 to rise, and the first ejector pins 2273 on the first ejector pin mounting plate 2272 pass through the end face of the placing table 2274 to eject the base detonators 8 in the loading die 4. Through the settings of the electric cylinder 2271, the first ejector pin mounting plate 2272, the first ejector pins 2273, and the placing table 2274 in cooperation with the loading die 4, the device can conveniently eject the base detonators 8 in the loading die 4 to facilitate the subsequent tube receiving step, and further improve the tube taking efficiency of the device.

[0075] The tube receiving device 228 includes a connecting seat 2281. At the lower end of the connecting seat 2281, there is a tube receiving box 2282. A limit switching plate 2283 is slidably installed in the tube receiving box 2282. On one side of the tube receiving box 2282, there is a push-pull cylinder 2284 whose output end is connected to the limit switching plate 2283. In the tube receiving box 2282, there are holes for accommodating the base detonators 8 and arranged in one-to-one correspondence with the positions of the loading die placing holes 41 in the loading die 4. On the limit switching plate 2283, there are combined through holes 2285 arranged in one-to-one correspondence with the positions of the loading die placing holes 41 in the loading die 4. The combined through holes 2285 are composed of large holes with an aperture adapted to the outer wall of the base detonator 8 and small holes with an aperture adapted to the outer wall of the first ejector pin 2273 along the moving direction of the limit switching plate 2283. That is, when the base detonators 8 are ejected from the tube withdrawing device 227 and enter the tube receiving device 228, the base detonators 8 and the upper ends of the first ejector pins 2273 pass through the large holes of the combined through holes 2285 of the limit switching plate 2283 and remain in the tube receiving box 2282. At this time, the push-pull cylinder 2284 drives the limit switching plate 2283 to move and switch, aligning the combined through holes 2285 into small holes, then lowering the first ejector pins 2273 and raising the tube receiving device 228. At this time, the base detonators 8 in the tube receiving box 2282 will not fall due to the obstruction of the small holes of the combined through holes 2285 on the limit switching plate 2283. Thus, the base detonators 8 are completely taken away and received by the tube receiving device 228. Through the settings of the connecting seat 2281, the tube receiving box 2282, the limit switching plate 2283, the push-pull cylinder 2284, and the combined through holes 2285 in cooperation with the loading die 4 and the tube withdrawing device 227, the device can conveniently and quickly take away the base detonators 8 ejected from the loading die 4 by the tube withdrawing device 227 by controlling the movement and switching of the limit switching plate 2283, and further improve the tube receiving efficiency of the device.

In this embodiment, the wiping floating medicine mold 5 on the receiving plate 22123 will first receive the basic detonator 8 sent from the tube receiving device 228, and then move to the lower end of the tube pressing device 2210, and the tube pressing device 2210 presses down the basic detonator 8 in the wiping floating medicine mold 5, so that the basic detonator 8 completely passes through the wiping floating medicine mold 5, and the steps of dropping and wiping floating medicine are completed. By setting the sliding seat 22121, the second cylinder 22122, the receiving plate 22123, the material passing hole 22124, and the positioning protrusion 22125 in coordination with the wiping and floating medicine mold 5, the device can further conveniently and quickly position and receive the wiping and floating medicine mold 5 and can move it to the material receiving and dropping position, which is convenient for subsequent steps.

[0081] Embodiment 5:

[0082] The specific working process of the present invention is as follows:

[0083] After the device is powered on and started, the transport rack 7 will begin to transport the filling mold 4 and the transfer mold 6, and its running direction is shown in the rotation detection device 19 in the figure.

[0084] When the filling mold 4 is in place after the rotating detection device 1, the transfer window is opened and the mold is pushed to the visual inspection station in the filling mold feed part 11. The filling mold feed part 11 is lifted up and down by the coordination of the visual detection device 14 and the lifting device 13, and the reinforcing cap of the basic detonator 8 in the filling mold 4 is inspected and the pipe mouth is inspected respectively to determine whether the reinforcing cap and the pipe mouth are qualified.

[0085] After the visual inspection is completed, the first turntable 15 is controlled to rotate, and the filling mold 4 is pushed to the drug height detection station in the first turntable 15 for the first inspection. The drug height detection device 16 detects part of the basic detonators 8 in the filling mold 4 to determine whether the drug height is within the qualified range; after the first drug height detection is completed, the first turntable 15 is controlled to rotate, and the filling mold 4 is transferred to the second drug height detection station for the second inspection. The second drug height detection device 16 detects the uninspected part of the basic detonators 8 in the filling mold 4 to determine whether the drug height is within the qualified range, and all inspections are completed.

[0086] After the inspection is completed, the first turntable 15 is controlled to rotate, and the filling mold 4 is transferred to the ejection position. The filling mold 4 is pulled out of the first turntable 15 by the discharge device 17 and pushed into the filling mold discharge part 12. The filling mold discharge part 12 enters the discharge device 17 again, and then is transported and continues the subsequent process.

[0087] First, the floating medicine mold material platform 21 transports the wiping floating medicine mold 5 and places it at the designated position of the receiving device 2212.

[0088] When the inspected filling mold 4 is in place after passing through the tube withdrawing and wiping floating medicine device 2, the transfer window is opened, and the filling mold 4 is pushed from the full tube filling mold feeding part 222 into the loading seat on the second turntable 226.

[0089] The second turntable 226 is controlled to rotate and cooperate with the filling mold pushing device 225 to push the filling mold 4 into the tube withdrawing device 227, and the electric cylinder 2271 is started to eject the basic detonator 8 in the filling mold 4 on the placement table 2274, and the tube collecting device 228 receives the ejected basic detonator 8 through the movement of the limit switching plate 2283.

[0090] After the basic detonator 8 of the loading mold 4 on the placement table 2274 is transferred away, the empty tube loading mold 4 will be pushed back from the tube withdrawal device 227 into the loading seat of the second turntable 226, and the second turntable 226 will be controlled to rotate, and the empty tube loading mold 4 will be rotated to the position aligned with the lifting and steering device 229, that is, the pushing position, and the loading mold pushing device 225 will push the empty tube loading mold 4 into the material table 2293 for lowering and rotation, and finally pushed from the empty tube loading mold discharge part 221 to the return transport rack 7.

[0091] Drive the tube collecting device 228 to move and transfer the basic detonator 8 to the top of the receiving device 2212, and switch the movable limit switch plate 2283 again to make the basic detonator 8 fall from the tube collecting device 228 into the floating medicine mold 5 in the receiving device 2212, and then drive the receiving device 2212 to move and drive the floating medicine mold 5 to the lower end of the tube pressing device 2210 for alignment.

[0092] After the empty tube transfer mold 6 on the transport rack 7 is moved and transported to the tube withdrawal and floating medicine removal device 2 in place, the transfer window is opened, and the empty tube transfer mold 6 is pushed in from the empty tube transfer mold feeding part 223, and after rotating and rising, it moves to the bottom of the pressure tube device 2210 and the receiving device 2212, that is, the material receiving position.

[0093] Start the tube pressing device 2210 to lower the punch needle inside it, push out the basic detonator 8 in the floating powder mold 5, let it pass through the floating powder mold 5 and the receiving plate 22123 and fall into the transfer mold 6, and push the full tube transfer mold 6 after loading is completed from the full tube transfer mold discharge part 224.

[0094] Finally, the grabbing and handling device 2211 grabs the full tube transfer mold 6, rotates and transfers it, transfers it to the transport rack 7, and is transmitted to the subsequent process by the transport rack 7.

[0095] After the transfer mold 6 on the transport rack 7 is moved and transported to the waste rejection device 3, the transfer mold 6 that has passed the first previous process will be pushed in from the transfer mold feed part 31 and stay in the designated preparation position. It will then determine whether to push up the basic detonator 8 based on the length of the basic detonator 8 produced and the jacking length of the jacking device 37.

[0096] If the inspection results of the previous inspection process for the transfer die 6 that moves to the waste rejection device 3 on the subsequent transport rack 7 are all qualified, it will directly pass through the waste rejection device 3 without being pushed into the waste rejection device 3, and continue to convey the transfer die 6 to the subsequent process.

[0097] If there are defective products in the inspection results of the previous inspection process, the transfer window is opened, and the transfer die 6 is pushed into the designated rejection position of the transfer die discharge part 32. By controlling the linear module X-axis 34 and the linear module Y-axis 35, the rejection clamp 36 is stopped above the defective base detonator 8 that needs to be rejected. The rejection clamp 36 is controlled to clamp out the defective base detonator 8, place the rejected defective product in the waste reimbursement oil pan 33, and continue to control the rejection clamp 36 to take out the base detonator 8 in the transfer die 6 on the transfer die feeding part 31 at the preparation position and put it into the transfer die 6 at the rejection position to fill it up. After the base detonator 8 in the transfer die 6 is filled up, it is pushed out from the transfer die discharge part 32, enters the transport rack 7 and continues to be conveyed to the next station.

[0098] When the base detonator 8 in the transfer die 6 at the preparation position in the waste rejection device 3 is replaced, the driving cylinder pushes it to the transfer side on one side, and a new full-tube transfer die 6 is pushed into the preparation position from the transfer die feeding part 31.

[0099] The entire working process of this device is completed. The present invention detects the appearance of the mouth of the base detonator 8 and the presence or absence of the booster cap through the visual inspection device 14, and batches the detection of the powder height in the base detonator 8 through the powder height detection devices 16 arranged at intervals to identify and judge whether the base detonator 8 is qualified; subsequently, the floating powder sticking to the tube wall during the production process of the base detonator 8 is solved by the powder wiping and floating powder device 2, providing safety guarantee for the operations in the subsequent processes. At the same time, during this process, the loading die 4 used to load the base detonator 8 is replaced with the transfer die 6 to facilitate the steps of packing and boxing in the subsequent processes; the unqualified products are rejected and replaced through the waste rejection device 3 to ensure the qualification rate of the final finished products. This device has high detection and screening efficiency and does not affect the continuity of the detection and screening production line throughout the process.
