DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings.

The handrails are bent from round tubes and welded to the square tubes at both ends of the rack to push the device. The electric control box is arranged on the second layer of the rack, and the operating button is set in the middle of the square tube in front of the rack;

[0025] The guide roller assembly includes a bearing seat 21, a bearing cover 22, a fixing ring 23, a seamless steel pipe 24 and a bearing 25. The bearing seat is installed on the two short sides of the top of the rectangular frame by screws, one on each side. The bearing cover is installed on the bearing seat, and a 0.5mm gap is designed between the bearing cover and the bearing seat to lock the bearing. The bearing is installed on the left and right ends of the seamless steel pipe, and the bearing is then seated on the bearing seat. The fixing ring is a step design, which is sleeved on both ends of the bearing, one on each side, and the shoulder is close to the bearing to prevent the bearing from moving left and right;

[0026] The detection component includes a double-acting linear motor 31, a drag chain 32, a drag chain fixing plate 33, a mover connecting plate 35, a sensor mounting plate 36, a beam laser sensor 37, a photoelectric mounting plate 38 and a photoelectric sensor 39. The double-acting linear motor is installed on the crossbeam and is used to move the sensor. The double-acting linear motor has its own grating scale to ensure the accuracy of detection. The drag chain and the drag chain fixing plate are installed on the frame to move the cables of this device. The sensor mounting plate is centrally mounted on the mover connecting plate by screws, and a number of mounting holes are provided on the top. The photoelectric mounting plate is mounted on the sensor mounting plate by screws. The beam laser sensor is mounted on the sensor mounting plate by screws, and the photoelectric sensor is arranged at a distance in front of the beam laser sensor and is mounted on the photoelectric mounting plate by screws.

[0027] A preferred example of the above scheme further includes a shock absorbing block, wherein the shock absorbing block is padded on the mover of the linear motor, and a mover connecting plate is installed on the upper side.

[0028] A preferred example of the utility model further includes a calibration component, which includes a mounting base plate 41, a pillar fixing sleeve 42, a guide shaft support 43, a guide shaft 44, a standard block support 45 and a standard block 46, and three groups are arranged in the length direction of one side of the beam. The mounting base plate is welded to one side of the large beam of the frame, and a plurality of screw holes are provided on the top. The pillar fixing clamp is installed on the mounting base plate through the above-mentioned screw holes, the guide shaft is clamped in the pillar fixing sleeve, and the guide shaft support is installed at the other end. The standard block support is installed on the two guide shaft supports, and a standard block is placed on the top for calibration of the device.

[0029] The automation principle is as follows: first, laser sensors are placed at both ends of the double-actuator linear motor, the laser sensors are driven by the double-actuator linear motor, and are connected to electrical measuring equipment respectively. A 24V DC power supply is selected as the power supply, and the electrical measuring equipment is used to measure the analog parameters of the laser sensors at both ends of the copper foil, such as current, voltage, etc.

[0030] After starting the device, the motor enables the laser sensor to move through the dual-acting linear motor. When the laser sensor detects the copper foil, the analog value changes, the motor stops running, the electrical equipment reads the sensor value, and calculates the width of the copper foil through the formula. When the dual-acting linear motor moves, the encoder calculates the current position and running distance. The electrical measuring equipment measures and records the electrical parameter values ​​at both ends of the copper foil in real time. These electrical parameter values ​​are associated with the width of the copper foil and can be converted through a pre-established correspondence. After the width is calculated, it is displayed on the touch screen and saved.

[0031] Next, based on the pre-established correspondence between the copper foil width and electrical parameters, the measured electrical parameters are converted into the actual width of the copper foil. This correspondence has been obtained through experimental data fitting and can also be obtained through theoretical calculation. In this way, the copper foil width can be accurately measured.

[0032] At the same time, the touch screen interface is simple and clear, which is convenient for employees to operate. It can also save and record the measured copper foil width size, which is convenient for finding records.

[0033] Implementation steps:

[0034] S1: When the device is used for the first time, calibrate the accuracy of the device. Reset the device first, then place the standard block on the standard block support in a side-positioned manner to ensure that the standard block and the incident laser sensor are level, then start the device to detect the width of the standard block and calibrate. Calibration is required on all three sets of calibration components to ensure the detection accuracy of the device.

[0035] S2: Lead the copper foil cut on the slitting machine to the seamless steel pipe of this device and straighten it.

[0036] S3: Start the equipment to detect the width of the copper foil. The opposing laser sensors on both sides approach the two sides of the copper foil at a faster speed. When the photoelectric sensor in front of the opposing laser sensor detects the end of the copper foil, the dual-actuator linear motor slows down and approaches the copper foil at a slower speed to detect the width.

[0037] Electrical parameter conversion process: When the laser sensor detects copper foil, it receives a current analog signal and inputs the signal into the PLC. After receiving the signal, the PLC issues a command to stop the double-acting linear motor. Then, the PLC calculates through a predetermined program: first, the total length of the double-acting linear motor is subtracted from the distance the double-acting linear motor has moved, and then the distance that the two sensors are blocked by the copper foil is added. After these calculation steps, the value obtained is the currently detected copper foil width.

[0038] The laser sensor has two key parameters: analog electrical signal and range. The range is 20mm, and the current signal range is set at 4-20mA. When the laser sensor is not blocked, it displays the upper limit of the current signal, 20mA; when the laser sensor is completely blocked, it displays the lower limit of the current signal, 4mA. Through the proportional relationship between the range of the laser sensor and the current signal range, the corresponding blocking range of any current value displayed by the sensor can be accurately calculated.

[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
