DETAILED DESCRIPTION
[0017] In order to make the content of the present application more easily understood, the present application will be further described in detail according to the specific embodiments and in conjunction with the drawings.
[0018] The embodiment of the present application provides a double-steel stamp synchronous printing device, which comprises a steel plate conveying roller 1, a first steel stamp printing mechanism and a second steel stamp printing mechanism. The first steel stamp printing mechanism and the second steel stamp printing mechanism can synchronously print steel stamps on both ends of the steel plate.
[0019] Specifically, the first steel stamp printing mechanism comprises a first slide rail 2 fixedly arranged above the steel plate conveying roller 1 and a first printing assembly 3 slidably arranged on the first slide rail 2. The first slide rail 2 extends along the width direction of the steel plate conveying roller 1, and one end of the first slide rail 2 extends into the steel plate conveying roller 1, so that the first printing assembly 3 can move to the upper side of the steel plate conveying roller 1 along the first slide rail 2, facilitating steel stamp printing work on the steel plate on the steel plate conveying roller 1.
[0020] The above-mentioned first printing assembly 3 comprises a pneumatic printing head, and the printing surface thereof is perpendicular to the surface of the steel plate.
[0021] The second stamp printing mechanism comprises a gantry assembly arranged above the steel plate conveying roller way 1 and a second printing assembly 6 arranged on the gantry assembly. The gantry assembly comprises two second sliding rails 4 fixedly arranged on both sides of the steel plate conveying roller way 1. A vertical column extending in the vertical direction is slidingly arranged on each second sliding rail 4. A cross beam 5 extending in the width direction of the steel plate conveying roller way 1 is fixedly arranged at the upper ends of the two vertical columns. A third sliding rail extending in the length direction of the cross beam 5 is arranged on the cross beam 5. The second printing assembly 6 is slidingly arranged on the third sliding rail. The second printing assembly 6 has the same structure as the first printing assembly 3 and also comprises a pneumatic printing head, and the printing surface thereof is also perpendicular to the surface of the steel plate.
[0022] In the embodiment, the first printing assembly 3 and the second printing assembly 6 are both driven by servo motors and ball screws to achieve high-precision positioning, and the positioning accuracy can reach ±0.1 mm.
[0023] A detection assembly for detecting the position of the steel plate is arranged on the steel plate conveying roller way 1. The detection assembly comprises a first laser sensor and a second laser sensor. The first laser sensor is arranged in two parts and symmetrically arranged on both sides of the steel plate conveying roller way 1, and the direction of the laser emitted by the first laser sensor is perpendicular to the conveying direction of the steel plate conveying roller way 1.
[0024] The second laser sensor is fixedly arranged at the front end of the steel plate conveying roller way 1, and the direction of the laser emitted by the second laser sensor is parallel to the conveying direction of the steel plate conveying roller way 1.
[0025] It should be noted that the first laser sensor and the second laser sensor are both located in the same horizontal plane as the steel plate on the steel plate conveying roller way 1. The first laser sensor detects the side edges of the steel plate, and the second laser sensor detects the front and rear edges of the steel plate.
[0026] An encoder is also arranged on the steel plate conveying roller way 1, which is located at the shaft end of the steel plate conveying roller way 1. The encoder outputs a fixed number of pulses per revolution, and the steel plate conveying distance is converted by pulse calculation, with a resolution of 0.05 mm / pulse.
[0027] The double-stamp synchronous printing device also comprises a main control assembly. The main control assembly is used for receiving data of the first laser sensor, the second laser sensor and the encoder, and controlling the operation of the steel plate conveying roller way 1, the first stamp printing mechanism and the second stamp printing mechanism based on preset parameters.
[0028] In the embodiment, the main control assembly adopts a PLC controller, which integrates a data processing unit and a driving control unit, can receive sensor signals, encoder pulses and preset parameters, and output control signals to servo motors and pneumatic valves of the stamp device.
[0029] In addition, the application also provides a double-steel seal synchronous printing method, which specifically comprises the following steps. Step S101: The steel plate size is preset, including the length L and the width W.
[0030] Specifically, in this embodiment, the steel plate with a length L=6000mm and a width W=1500mm is taken as an example, and the operator inputs the steel plate length and the steel plate width on the human-computer interaction interface of the main control assembly.
[0031] Step S102: The steel plate is conveyed by the steel plate conveying roller 1, and the encoder counting is triggered when the front end of the steel plate is detected by the second laser sensor, so as to record the conveying distance S of the steel plate in real time.
[0032] Specifically, the steel plate is conveyed forward by the steel plate conveying roller 1. The front end of the steel plate triggers the second laser sensor, so that the second laser sensor sends a signal to the main control assembly, and the main control assembly controls the encoder to start counting, so as to obtain the conveying distance S of the steel plate in real time.
[0033] Step S102: The steel plate edge position is detected by the first laser sensor, the center offset amount Δ of the steel plate in the conveying path is obtained, and the printing reference point of the first steel seal printing mechanism is determined.
[0034] Specifically, the first laser sensor on both sides of the steel plate conveying roller 1 detects the side edge of the steel plate in real time, and the offset amount Δ of the center of the steel plate from the center of the conveying path is calculated. In this embodiment, the offset amount Δ=5mm, that is, the steel plate is offset by 5mm to the left.
[0035] The main control assembly calibrates the printing position of the first steel seal printing mechanism to the position of “the first end edge of the steel plate inward by 50mm+Δ”, which is the printing reference point of the first steel seal printing mechanism.
[0036] Step S103: When the conveying distance S of the steel plate is equal to the preset printing distance S1 of the first steel seal printing mechanism, the first printing assembly 3 is controlled to print the steel seal at the first end of the steel plate, and the target printing position of the second steel seal printing mechanism is calculated based on the steel plate length L, the conveying distance S and the center offset amount Δ, and the second steel seal printing mechanism is driven to move to the target printing position, so that the second printing assembly 6 synchronously prints the steel seal at the second end of the steel plate.
[0037] Specifically, when the encoder counts the corresponding conveying distance S = 50 mm (i.e. the first end of the steel plate reaches the printing position of the first steel stamp printing mechanism), the main control assembly drives the first printing assembly 3 of the first steel stamp printing mechanism to act, and the first end steel stamp printing is completed. At the same time, the main control assembly calculates the target position of the second end steel stamp on the steel plate, and the calculation principle is as follows: target distance S2 = steel plate length L - first end printing distance (50 mm) + offset Δ = 6000 - 50 + 5 = 5955 mm. At the same time, the main control assembly drives the second steel stamp printing mechanism to run, so that the second printing assembly 6 moves along the guide rail to a position 5955 mm away from the starting point. When the encoder count shows that the conveying distance of the steel plate reaches 5955 mm, the second end of the steel plate reaches the printing position of the second steel stamp printing mechanism, and the main control assembly drives the second printing assembly 6 to act, and the steel stamp printing is completed synchronously with the first end (time difference ≤ 0.1 s).
[0038] It can be understood that for steel plates of different sizes, only the length and width parameters need to be updated in the main control assembly, and the device can automatically repeat the above steps to realize dynamic positioning of the movable steel stamp device and ensure that the positions of the two ends of the steel stamp are always symmetrical (deviation ≤ 0.5 mm).
[0039] Therefore, the technical scheme of the present application realizes accurate positioning of the first steel stamp printing mechanism and the second steel stamp printing mechanism through the combination of encoder and laser sensor detection and servo motor driving, and the steel stamp printing actions of the two ends are completed synchronously, which improves the efficiency by more than 50% compared with single-end printing and reduces the waiting time of steel plate conveying.
[0040] In addition to the above embodiments, the present application can have other implementation manners; any technical scheme formed by equivalent substitution or equivalent transformation falls within the protection scope required by the present application.
