Description

Technical Field

[0001] The invention relates to the technical field of electronic detonator production, in particular to an inner wall floating medicine wiping device for basic detonator production. Background Art

[0002] During the production of basic detonator filling, the filling agent is measured by a metering plate and then falls into the tube shell in a free fall manner. During the falling process, the powder will adhere to the inner wall of the tube shell, which may cause friction with the control module during the subsequent assembly of the electronic detonator, posing a safety hazard.

[0003] At present, the method for treating the floating drugs on the inner wall of the tube shell is to clean the floating drugs through mechanical reciprocating cycle vibration. However, this method has the problem of whether the floating drugs in the tube can be cleaned thoroughly.

[0004] The inner wall wiping technology has the same principle as the present invention, but lacks the combined mold flipping mechanism. The wiping punch directly extends into the tube wall from the top to wipe it. Alcohol will flow into the tube under the influence of gravity and wet the reagent, causing the basic detonator to fail.

[0005] To this end, the present invention provides an inner wall floating medicine wiping device for basic detonator production, which solves the problem of floating medicine generated during the basic detonator production being stored on the inner wall of the tube shell, thereby eliminating safety hazards. Summary of the Invention

A wiping drive cylinder is installed on the wiping drive cylinder bracket, and its piston rod is connected to the flip plate support block to achieve precise wiping of the combination mold surface and punch hole.

[0016] Preferably, it also includes an automatic control system, which adopts a PLC controller, the input port is connected to the combination module position sensor, and the output port controls the solenoid valves of each cylinder through a relay.

[0017] Preferably, a polyurethane cushion is provided at the bottom of the horizontal section of the L-shaped push plate, and a pressure sensor is provided on the contact surface with the combined mold. When the detected pressure is ≥40N, the PLC controls the double-rod cylinder to retreat.

[0018] Preferably, an annular groove is provided on the inner wall of the conical step hole, which forms a snap fit with the outer flange of the base detonator tube mouth, ensuring that the axial positioning accuracy of the detonator is ≤0.1mm during the wiping process; the wiping rotary cylinder main shaft is provided with an angle encoder, and the limit switch is triggered when the flip plate is rotated to 180°, ensuring that the cotton swab section is completely immersed 5mm below the liquid level of the alcohol tank when the punch is dipped in alcohol; a drainage hole is provided at the bottom of the alcohol tank positioning plate, and a matching collection tray is provided.

[0020] The present invention provides a device for wiping the inner wall floating powder for basic detonator production. It has the following beneficial effects:

[0021] (1) The present invention adopts a five-step process of "pushing-grabbing-flipping-wiping-cleaning". The combination mold pushing component accurately pushes the combination mold to the grasping station through the coordinated action of the L-shaped push plate and the double-rod cylinder; the grasping and flipping component uses the 50 conical step holes of the upper clamping plate and the L-shaped positioning strip of the lower clamping plate to achieve axial and radial dual positioning of the detonator tube mouth. The grasping telescopic cylinder drives the clamping plate to close with a 10mm stroke to ensure a positioning accuracy of ≤0.1mm; then the grasping rotary cylinder flips the combination mold 180° so that the tube mouth faces downward, effectively preventing alcohol from flowing into the tube under the action of gravity during wiping, and effectively solving the problems of high floating drug residue rate and easy damage to the tube shell in the traditional mechanical vibration cleaning method.

[0022] (2) The present invention adopts a closed-loop process of "dipping-wiping-flipping-secondary cleaning". The 50 punches with cotton swabs of the wiping and flipping assembly are interference-fitted into the through holes of the punch positioning plate. The wiping telescopic cylinder drives the punch into the tube with a stroke of 30 mm, and cooperates with the 180° flipping action of the wiping rotary cylinder to ensure 360° full contact between the cotton swab and the tube wall. During cleaning, the punch is lowered into the alcohol tank to dip in the solution. The alcohol tank positioning plate is designed with a 2° inclined groove to achieve rapid positioning and residual liquid diversion. The matching collection tray can recover more than 95% of residual alcohol, effectively solving the problem of solution residue easily caused by alcohol cleaning.

[0023] (3) The present invention integrates a PLC automatic control system to achieve unmanned intervention in the entire process. After the combination mold is in place sensor is triggered, the PLC controls the actions of each cylinder (pushing → grabbing → flipping → wiping → cleaning → pushing out) according to a preset program. The interval between each step is 0.5s, and the single-cycle processing time is ≤8s; the touch screen displays the cylinder status, pressure value and fault code (such as E01 combination mold not in place, E02 grabbing pressure abnormality) in real time, and supports parameter settings such as the number of wiping times (adjustable from 1 to 5 times) and the alcohol soaking time (adjustable from 3 to 10s), thereby achieving a high-precision and high-efficiency production process and ensuring that the cleanliness of the inner wall of the detonator is improved.
