However, dangerous processes such as demolding, sorting, and bagging after the automated assembly line are still mainly manual operations, which has become a bottleneck for the industry to achieve unmanned development.

[0003] The automated assembly of industrial detonators generally involves placing a group of industrial detonators in a special loading mold, where the basic detonator (hereinafter referred to as the detonator) is fixed in a fixed slot on one side of the loading mold with the help of a sealing plug, the wire clip is fixed on the other side frame, and the wire handle is stored in the loading mold. The packaging of industrial detonators mainly consists of demolding, sorting, bagging, labeling, packing, and sealing processes. Since the conductors of industrial detonators are generally made of iron metal wires coated with insulating materials, the metal core wires at both ends are difficult to shape, and there are many wire length specifications, the wire handles are of different sizes, and the bagging specifications are also varied. It is difficult for one device to fully meet the requirements.

Cylinder 705 contracts, causing mechanical grabber 706 to move along limit slide column 707 to grab and collect the group detonator wire handles at one time, then the seventh cylinder 703 contracts to lift the clamp plate 704, and then the mounting plate 702 moves along the second slide rail 6 to the top of the U-shaped groove inner box 303 through the second slider 701, the seventh cylinder 703 extends, and then the eighth cylinder 705 extends, causing the mechanical grabber 706 to put the detonator wire handle into the U-shaped groove inner box 303, and the automatic tube collection and feeding mechanism 7 is reset, the second cylinder 304 pushes the folding window 306 to close through the connecting piece 305, and the first cylinder 301 drives the lifting The outer box 302 descends, and the wire handle is compressed by the closed folding window 306.

Then the push rod 307 pushes the compressed detonator and the wire handle to move through the sorting channel 401 into the plastic film bag with three sides sealed. Then the push rod 307 continues to push the detonator to move, so that the detonator drives the plastic film bag to move onto the loading platform 9, and the push rod 307 can be reset. When the detonator and the plastic film bag are moving, the third cylinder 404 pushes the heat sealing knife head 405 to continue heat sealing the top of the packaging film behind, and the plastic film bag is wrapped. After the detonator moves to the loading platform 9, the sixth cylinder 412 pushes the closed tightening door 413 to clamp the unsealed end of the plastic film bag, and then the fourth cylinder 409 extends out, driving the mounting frame 406 and the first slider 407 to move along the first slide rail 408, so that the closed tightening door 413 scrapes the detonator wire toward the sealed end of the plastic film bag, so that the industrial detonator is closer to the bottom of the plastic film bag.

Two groups of second slide blocks are arranged at the bottom of the mounting plate, and the mounting plate is slidably connected to the second slide rail through the second slide block. The mechanical picker is a universal upright "L"-shaped mechanical hand that can be freely opened and closed in the horizontal direction, and can also be a group of special-shaped mechanical pickers. A loading platform is arranged on the top of the second working frame between the first slide rails, and the loading platform and the sorting channel are located on the same horizontal line.

2. The channel-type automatic sorting and packaging machine for group-fired industrial detonators according to claim 1 is characterized by: The automatic feeding and sorting mechanism also includes a second cylinder and a connecting piece. A connecting piece is provided at one end of the top of the folding window, and a second cylinder with an output end rotatably connected to the connecting piece is rotatably installed on both sides of the lifting outer box.

3. The channel-type automatic sorting and packaging machine for group-fired industrial detonators according to claim 1 is characterized by: Guide columns connected to the parts connected to their respective output ends are arranged on both sides of the first cylinder, the third cylinder, the fifth cylinder, the sixth cylinder and the seventh cylinder, and the guide columns are slidably connected to the respective mounting positions of the first cylinder, the third cylinder, the fifth cylinder, the sixth cylinder and the seventh cylinder.

4. The channel-type automatic sorting and packaging machine for group-fired industrial detonators according to claim 3 is characterized by: All the guide posts and their sliding connections are provided with linear bearings.

5. The channel-type automatic sorting and packaging machine for group-fired industrial detonators according to claim 1 is characterized by: The lifting outer box and the U-shaped groove inner box are both rectangular structures with both ends and the top open, and the end of the sorting channel close to the automatic feeding sorting mechanism is a rectangular structure that matches the U-shaped groove inner box.

6. A method for packaging industrial detonators, characterized in that: The channel-type automatic sorting and packaging machine for group-fired industrial detonators according to any one of claims 1 to 5 comprises the following steps: The automatic tube collecting and feeding mechanism is used to grab group-fired industrial detonators. The mechanical grabber of the automatic tube collecting and feeding mechanism can grab at least two detonators at the same time, and can be translated to the top of the automatic feeding and sorting mechanism through the second slide rail provided on the frame, and can release all the detonators carried by the mechanical grabber at one time; The automatic feeding and sorting mechanism is used to receive all the detonators released by the mechanical copying hand, and complete the sorting of all the detonators through the U-shaped groove inner box constraint and the lifting and squeezing of the lifting outer box, and then the pushing rod pushes all the detonators through the sorting channel into the plastic film cylinder or preformed plastic film bag made on site; The bag making method of the automatic packaging and sealing mechanism is that the plastic film is made online through a sorting channel and a heat sealing knife and a heat sealing and slitting knife arranged outside the sorting channel, or the packaging bag can be provided by a general bag making machine or a pre-made bag feeding and opening mechanism arranged outside the sorting channel; The plastic film bag sealing and cutting method of the automatic packaging bag sealing mechanism is as follows: the third cylinder pushes the heat sealing knife head to heat-seal and bond the top of the rear packaging film, and after the detonator wrapped in the plastic film bag continues to move to the loading platform, the sixth cylinder pushes the closing and tightening door to clamp the unsealed end of the plastic film bag, and then the fourth cylinder extends out, driving the first slider of the mounting frame to move along the first slide rail, so that the closing and tightening door scrapes the detonator toward one end of the sealed plastic film bag, so that the industrial detonator is closer to the bottom of the plastic film bag, and at the same time a small space is scraped out at the other end of the plastic film bag, and the fifth cylinder pushes the heat sealing and slitting knife to clamp the plastic film bag, and heat-seal and cut the plastic film bag.
