Description

Technical Field

[0001] The present invention relates to a welding test production line for an ignition element of an electronic detonator, belonging to the field of detonator production equipment. Background Art

[0002] Currently, in the production of industrial digital electronic detonators, it is usually necessary to solder the primer with the chip. The combination of the chip and the detonator leg wire fixed together by a rubber plug constitutes the lead end. In order to achieve assembly line production, it is necessary to arrange the lead ends on the corresponding welding molds, and at the same time load the primers cut from the primer steel strip and tested to be qualified onto the welding molds for continuous welding operations; after welding, it is necessary to transfer it to the inspection process for inspection, and finally remove the completed electronic detonators from the welding molds. Among them, in the die arranging and die withdrawing processes, manual operations are required for die arranging and tube withdrawing on the welding molds. The welding mold is a rectangular box body, and a welding front plate is provided at one end of the rectangular box body. On the welding front plate, there are successively a primer clamp, a circuit board clamp, and a leg wire clamp, which can neatly arrange the primers, circuit boards, and leg wires of multiple electronic detonators on the corresponding clamps to complete welding and inspection at one time. In order to ensure the continuous and stable subsequent operations, manual workers precisely place or take out each electronic detonator one by one, which is time-consuming and laborious. Generally, 3 to 4 people are required to meet the production needs; in the primer steel strip shearing and testing processes, in order to ensure the continuous and stable processes, workers often need to adjust the feeding speed of the primer steel strip; therefore, in the entire process flow, a large number of workers are still required to participate, the labor intensity of the workers is high, the production efficiency is low, and the production cost is high. And because electronic detonators are highly dangerous products that are flammable and explosive, the existing equipment has not well achieved human-machine isolation, and the operators directly contact the detonators, so the personnel are at high risk and there are relatively large safety hazards.

[0003] In view of this, the purpose of the present invention is to provide a welding test production line for an ignition element of an electronic detonator, which can overcome the deficiencies of the prior art.

[0022] As Figure 1 shown, a welding test production line for an electronic detonator ignition element disclosed by the present invention is used for welding and detecting the production of the medicine head and the chip at the lead end of the electronic detonator, and includes a conveying mechanism and more than one mold 12 for electronic detonator welding test that can move on the conveying mechanism.

[0023] The specific working process is as follows: The welding test mold 12 with the lead end component is transported to the lower part of the automatic secondary die arranging device 2 through the first conveying mechanism 1. The automatic secondary die arranging device 2 grabs the lead end rubber plug and automatically arranges it in the corresponding card slot on the welding test mold 12. After the die arranging is completed, it is transported to the discharge port of the first conveying mechanism 1. The telescopic electric suction cup of the first film suction mechanism 3 sucks the welding test mold 12 and places it on the second conveying mechanism 4. The second conveying mechanism 4 transports it to the lower part of the automatic medicine feeding head, punching test and die arranging integrated equipment 5. The automatic medicine feeding head, punching test and die arranging integrated equipment 5 completes the operations of automatic medicine feeding head, punching and testing of the medicine head steel strip, and arranges the qualified medicine heads one by one on the welding test mold 12. Then, the second conveying mechanism 4 transports it to the welding equipment 6 and the laser detection equipment 7 in sequence to complete welding and testing. Then, it is transported to the discharge port of the second conveying mechanism 4. The telescopic electric suction cup of the second film suction mechanism 8 sucks the welding test mold 12 and places it on the third conveying mechanism 9. The third conveying mechanism 9 transports it to the automatic pipe withdrawing equipment 10 to complete the automatic pipe withdrawing operation. Finally, the operation of storing the electronic detonator is carried out, and the empty welding test mold 12 is transported by the fourth conveying mechanism 11 to the die arranging process point for recycling.

[0024] See Figure 2 and Figure 3, the automatic secondary die arranging device 2 includes a mounting frame 201 fixedly connected to one side of the first conveying mechanism 1. A sliding table 202 is provided on the mounting frame 201. A sliding mechanism capable of moving horizontally, longitudinally, and vertically relative to the workbench surface and a pneumatic manipulator connected thereto are provided on the sliding table 202. The sliding mechanism includes a horizontal slide rail 203 provided on the sliding table 202 and perpendicular to the workbench surface. A horizontal slide block 204 is provided on the horizontal slide rail 203. A horizontal air cylinder 5 is connected to the back of the horizontal slide block 204. The horizontal slide block 204 is pushed by the horizontal air cylinder 5 to realize its horizontal sliding relative to the workbench surface. A longitudinal slide rail 206 parallel to the workbench surface is provided inside the horizontal slide block 204. A longitudinal slide block 207 is installed on the longitudinal slide rail 206. The longitudinal slide block 207 realizes its longitudinal sliding relative to the workbench surface by a stepping motor 208 provided on the back of the horizontal slide block 204. A vertical slide rail 209 is provided at the front end of the longitudinal slide block 207. A gripper support 210 is provided on the vertical slide rail 209. The top of the gripper support 210 is connected to an up-and-down air cylinder 211. The gripper support 210 is pushed by it to realize its up-and-down sliding relative to the workbench surface. The pneumatic manipulator is installed on the gripper support 210. The pneumatic manipulator includes a gripper 212 and a gripper air cylinder 213 connected thereto. The gripper air cylinder 213 is fixedly connected to the gripper support 210. The gripper 212 is provided at the bottom of the gripper air cylinder 213. At least two pairs of the grippers 212 are arranged in parallel. The structure of the gripper 212 is adapted to the rubber plugs at the lead ends of detonators. At least two rubber plugs can be grabbed at one time by the gripper 212 for die arranging.

[0025] See Figure 4 , the automatic medicine head feeding, punching and testing, and die arranging integrated equipment 5 includes a frame 501 fixedly connected to one side of the second conveying mechanism 4. A gripper feeding mechanism 503 is provided on the tabletop of the frame 501. A medicine head steel belt through slot 504 is opened on the frame 501 beside the gripper feeding mechanism 503. A medicine head separating mechanism 502 capable of separating the medicine head steel belt from the magnetic tape is provided below the medicine head steel belt through slot 504 and on the left side of the gripper feeding mechanism 503. A transition guiding mechanism 505, a demagnetizing mechanism 506, a punching and testing mechanism 507, and a die arranging mechanism 508 are sequentially arranged on the tabletop of the frame 501 on the right side of the gripper feeding mechanism 503. The medicine head steel belt and the magnetic tape are separated by the medicine head separating mechanism 502, and the medicine head steel belt is passed out through the medicine head steel belt through slot 504. The gripper feeding mechanism 503 gradually grabs it to realize the linear feeding of the medicine head steel belt, and the medicine head steel belt sequentially passes through the transition guiding mechanism 505, the demagnetizing mechanism 506 to the punching and testing mechanism 507 for shearing, and the resistance value of the cut medicine head is tested to eliminate defective products. Finally, the qualified medicine heads are sent to the die arranging mechanism 508, and the qualified medicine heads are arranged one by one on the welding test die 12.

[0026] On one side of the gripper feeding mechanism 503, there is an optoelectronic sensor 509. The optoelectronic sensor 509 is used to send corresponding signals to the PLC control system, and the PLC control system controls the automatic grasping operation of the gripper feeding mechanism 503. Specifically, during the process of the gripper feeding mechanism 503 gradually grasping to achieve the linear feeding of the detonator steel strip, when the detonator steel strip abuts against the optoelectronic sensor 509, it indicates that the front section of the detonator steel strip is fed sufficiently, meeting the requirement for the punching and testing mechanism 507 to continuously shear the detonator. To prevent waste caused by excessive front-end feeding, the optoelectronic sensor 509 sends real-time information to the PLC control system, and the PLC control system sends a stop grasping signal to the gripper feeding mechanism 503. Conversely, when the detonator steel strip does not abut against the optoelectronic sensor 509, the gripper feeding mechanism 503 performs grasping and feeding.

[0027] See Figure 5 , the automatic tube withdrawal device 10 includes a mold placement table 1001 provided at the connection part between the discharge port of the third conveying mechanism 9 and the feeding end of the fourth conveying mechanism 11. There is a gap between the mold placement table 1001 and the feeding end of the fourth conveying mechanism 11. An elevating ejector rod mechanism 1002 is provided at the gap, and a baffle structure 1003 that cooperates with it is provided in the front section above the elevating ejector rod mechanism 1002; the baffle structure 1003 is misaligned relative to the elevating ejector rod mechanism 1002; when the welding test mold 12 with electronic detonators placed in it is transported to the mold placement table 1001 through the third conveying mechanism 9, the front section of the detonator assembly of the electronic detonator is placed directly below the baffle structure, and the elevating ejector rod mechanism rises to push the rear section of the detonator assembly of the electronic detonator, so that the detonator assemblies of multiple electronic detonators can be taken out of the card slots of the welding test mold 12 at one time. Finally, the empty fixture is transported to the mold arranging process point through the fourth conveying mechanism 11 for recycling.
