Description

Technical Field

[0001] This utility model relates to the field of laser calibration devices, and more particularly to a laser calibration device for a slitting machine. Background Technology

[0002] During the operation of the slitting machine, the take-up roller needs to be precisely installed in a specific axial position on the mounting rod to ensure smooth slitting and winding processes. Traditionally, this installation and positioning process usually relies on manual measurement and visual comparison using rulers.

[0003] Due to limitations in the accuracy of manual measurement, this installation method is prone to positioning deviations caused by visual errors or incorrect measurement methods, resulting in the take-up roller not being installed correctly, thus affecting subsequent winding operations. Utility Model Content

[0004] The purpose of this invention is to provide a laser calibration device for slitting machines to solve the problem of low accuracy caused by relying on manual measurement for the installation of receiving rollers in the prior art.

[0005] The technical solution of this utility model is: a laser calibration device for a slitting machine, comprising: The mounting bracket has a pair of parallel walls; The mounting rod has an axis along the horizontal direction; both ends of the mounting rod are rotatably connected to a pair of wall surfaces respectively; The receiving roller is fitted onto the mounting rod; The calibration components include a laser, a calibration drive mechanism, and a control unit; The laser is capable of emitting a laser beam and illuminating the mounting rod; The laser can slide in a direction parallel to the mounting rod under the drive of the calibration drive mechanism; The control unit is electrically connected to the calibration drive mechanism and configured to control the calibration drive mechanism to move the laser to a preset position, so that the laser beam irradiates the corresponding point on the mounting rod.

[0006] Preferably, the calibration drive mechanism includes a calibration rod, a driver, and a transmission part. The calibration rod is arranged parallel to the mounting rod and its two ends are fixed to the mounting frame. The driver drives the laser to slide along the calibration rod through the transmission part.

[0007] Preferably, the laser is configured as a line laser.

[0008] Preferably, the laser is connected to the transmission unit via an adjustment mechanism. The adjustment mechanism includes an adjustment base, which is fixed to the transmission unit. A first adjustment pair is provided on the adjustment base. The first adjustment pair includes a first fixed part and a first movable part. The laser is directly or indirectly connected to the first movable part. The first movable part is rotatably connected to the first fixed part around a horizontal axis along a first direction.

[0009] Preferably, the adjustment mechanism includes a second adjustment pair, which includes a second fixed part and a second movable part. The second fixed part is fixed to the end of the first movable part away from the first fixed part. The laser is directly connected to the second movable part. The second movable part is rotatably connected to the second fixed part about a horizontal axis along a second direction, which is perpendicular to the first direction.

[0010] Preferably, the transmission unit includes a lead screw mechanism fixed on the calibration rod, a slider slidably disposed on the lead screw mechanism, an adjustment mechanism fixed on the slider, and the slider sliding along the length direction of the calibration rod under the drive of the driver.

[0011] Compared with the prior art, the advantages of this utility model are: (1) A clear light spot is formed on the mounting rod by a laser as a calibration reference, which effectively avoids visual errors caused by human observation, so that the end face of the receiving roller can be precisely aligned with the laser indicator line, thereby achieving installation positioning accuracy far exceeding that of traditional manual measurement.

[0012] (2) By connecting the control unit and the calibration drive mechanism electrically, the operator only needs to input the target position parameters, and the calibration drive mechanism can move the laser to the designated point, thus avoiding the problem of errors in manual measurement.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 and 2 As shown, a laser calibration device for a slitting machine includes a mounting frame 1, a mounting rod 2, a take-up roller 3, and a calibration assembly 4.

[0015] The mounting frame 1 is made of metal and has a pair of parallel walls that support the entire device. The mounting rod 2 has a horizontal axis, and its two ends are rotatably connected to the pair of walls via bearings. The take-up roller 3 is fitted onto the mounting rod 2 to take up the slit material and rotates synchronously with the mounting rod 2.

[0016] During the process of installing the take-up roller 3 onto the mounting rod 2, it is necessary to set up a calibration component 4 to calibrate the axial position of the take-up roller 3 on the mounting rod 2.

[0017] Combination Figure 3 and Figure 4 As shown, the calibration assembly 4 includes a laser 41, a calibration drive mechanism 42, and a control unit. The laser 41 is preferably a line laser 41, which emits a linear laser beam and illuminates the mounting rod 2 to form a linear calibration position on the mounting rod 2. When a reference point on the take-up roller 3, such as the vertical end face of the take-up roller 3, coincides with the linear calibration position, the take-up roller 3 is considered to be in the correct mounting position.

[0018] The laser 41 is mounted on the calibration drive mechanism 42 and can slide parallel to the mounting rod 2 under the drive of the calibration drive mechanism 42. The control unit is a computer program and is electrically connected to the calibration drive mechanism 42. The operator inputs the calibration position into the control unit, and the control unit controls the calibration drive mechanism 42 to drive the laser 41 to the target position. This allows the laser beam to irradiate the corresponding point on the mounting rod 2, thereby calibrating the installation position of the take-up roller 3.

[0019] Specifically, the calibration drive mechanism 42 includes a calibration rod 421, a driver 423, and a transmission part 422. The two ends of the calibration rod 421 are fixed to the mounting bracket 1 and are arranged parallel to the mounting rod 2. The transmission part 422 and the driver 423 are both fixed to the calibration rod 421.

[0020] The transmission unit 422 includes a lead screw mechanism fixed to the calibration rod 421. The lead screw mechanism is driven by the driver 423, and the actuator end of the lead screw mechanism is provided with a slider. The laser 41 is directly or indirectly connected to the slider.

[0021] In a preferred embodiment of this application, the laser 41 is connected to the slider via an adjustment mechanism 5. The adjustment mechanism 5 is used to adjust the angle of the linear laser beam emitted by the laser 41, allowing the linear laser beam to remain vertical even when the calibration rod 421 is not strictly horizontal.

[0022] Specifically, the adjustment mechanism 5 includes an adjustment base 51, which is fixed to the slider. A first adjustment pair is provided on the adjustment base 51, comprising a first fixed part 52 and a first movable part 53, with the laser 41 connected to the first movable part 53. The first fixed part 52 is connected to the adjustment base 51, and the first movable part 53 is rotatably connected to the first fixed part 52, allowing it to swing around a horizontal axis along a first direction, thereby causing the laser 41 to swing and adjusting the angle of the linear laser beam on the horizontal plane.

[0023] Furthermore, the adjustment mechanism 5 also includes a second adjustment pair, which includes a second fixed part 54 and a second movable part 55. The second fixed part 54 is fixed to the end of the first movable part 53 away from the first fixed part 52, and the laser 41 is directly connected to the second movable part 55. The second movable part 55 is rotatably connected to the second fixed part 54 and can swing around an axis parallel to a second direction, wherein the second direction is perpendicular to the first direction. This allows for adjustment of the pitch angle of the laser 41, thereby adjusting the irradiation height of the laser beam to adapt to the installation operations of the receiving rollers 3 at different heights.

[0024] During work: The operator adjusts the two angles of the laser 41 relative to the first and second directions beforehand using the adjustment mechanism 5. This ensures that the emitted linear laser beam is parallel to the end face of the take-up roller 3 and that the laser beam can irradiate the mounting rod 2.

[0025] The specific location where the take-up roller 3 needs to be installed is then input into the control unit. The laser 41 generates a laser beam and runs to the corresponding position under the drive of the calibration drive mechanism 42, so that the laser beam irradiates the target position of the take-up roller 3 on the mounting rod 2, which is used to assist the assembly personnel in the installation operation of the take-up roller 3.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
