Description

Technical Field

[0001] This utility model belongs to the technical field of foil making machine, and specifically relates to a foil making machine edge tearing alarm. Background Technology

[0002] Edge tearing is a common quality problem in the production of electrolytic copper foil during the foil-making process. Once it occurs, it not only affects the appearance and performance of the product but may also adversely impact subsequent production processes. To promptly detect and address edge tearing, existing foil-making machines are typically equipped with alarm systems. When edge tearing occurs, the alarm system triggers an audible alarm to alert staff to take action.

[0003] Existing foil-forming machine edge-tearing alarms, while meeting the basic requirement of detecting whether copper foil is tearing and triggering an alarm when tearing is detected, often have limitations. The horizontal position of the monitoring probe on the mounting frame is not easily adjustable and is fixed to the mounting structure with bolts. This means that when the width of the processed copper foil changes, it is necessary to use tools to adjust the position of the monitoring probe, which is time-consuming and laborious, before monitoring can begin. This causes great inconvenience to users and affects the overall efficiency of the foil-forming machine. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a foil-making machine edge-tearing alarm. It not only meets the basic requirement of detecting and alarming whether copper foil is torn at the edge, but also allows for flexible and convenient adjustment of the horizontal position of the monitoring probe, making the position of the monitoring probe compatible with the side end position of different copper foils, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a foil-making machine edge-tear alarm, including a base set on the side of the foil-making machine, a vertical plate set on the base, a horizontal plate set on the vertical plate extending to the upper side of the foil-making machine guide roller, a mounting groove set at the bottom of the horizontal plate, a bidirectional screw rotatably set in the mounting groove, a drive motor set on the mounting groove for driving the rotation of the bidirectional screw, mounting blocks slidably connected to the mounting groove are screwed to both sides of the bidirectional screw, a monitoring probe is set on each of the two mounting blocks, and a controller electrically connected to the monitoring probe and an alarm module electrically connected to the controller are also set on the vertical plate.

[0006] As a further improvement of this utility model, the alarm module includes a buzzer and a flashlight mounted on the vertical plate, both of which are electrically connected to the controller. The alarm module, including the buzzer and flashlight, can simultaneously emit an audible and visual alarm to remind operators to promptly address the tearing issue; this combined audible and visual approach is suitable for noisy production environments, ensuring that alarm information is not ignored.

[0007] As a further improvement of this utility model, a rotating shaft is provided at the top of the vertical plate, and a connecting sleeve rotatably connected to the rotating shaft is provided on the horizontal plate. A connecting bolt is also provided on the connecting sleeve, and a connecting hole adapted to the connecting bolt is provided on the connecting shaft for connecting the horizontal plate located above the guide roller. When maintenance of the bidirectional screw and monitoring probe is required, simply separate the connecting bolt from the connecting hole, then rotate the horizontal plate 90 degrees from the upper side of the guide roller to the outer end of the guide roller, thus facilitating maintenance of the bidirectional screw and monitoring probe.

[0008] As a further improvement of this utility model, the connecting bolt is a hand-tightening bolt. Users can easily adjust the hand-tightening bolt by hand.

[0009] As a further improvement of this utility model, a support plate is also provided on the vertical plate to support the horizontal plate. This provides auxiliary support to the horizontal plate, making it more stable during operation.

[0010] As a further improvement of this utility model, a reinforcing plate is also provided between the base and the vertical plate. This enhances the connection strength between the vertical plate and the base.

[0011] As a further improvement of this utility model, a fixing plate is provided on the base, and fixing bolts for fixing to the foil-making machine are provided on the fixing plate. Fixing holes for installing the fixing bolts are also provided on the fixing plate. Through the cooperation of the fixing plate, fixing bolts and threaded fixing holes, the base and foil-making machine can be flexibly fixed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, by using two monitoring probes to monitor the edges of the copper foil in real time, it is possible to quickly and accurately detect whether the copper foil has been torn. When the controller detects that the copper foil has been torn, it will sound an alarm through the alarm module to report the abnormality to the workers.

[0014] Secondly, the design of the bidirectional screw allows for flexible adjustment of the horizontal position of the two monitoring probes to match the side positions of copper foils of different specifications. The drive motor drives the bidirectional screw to rotate, achieving automated adjustment that is easy to operate and highly accurate. Attached Figure Description

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 3 As shown in Figure 4, a foil-making machine edge-tear alarm includes a base 101 disposed on the side of the foil-making machine. A vertical plate 102 is disposed on the base 101, and a horizontal plate 103 extending to the upper side of the foil-making machine guide roller is disposed on the vertical plate 102. A mounting groove 104 is disposed at the bottom of the horizontal plate 103. A bidirectional screw 105 is rotatably disposed in the mounting groove 104. A drive motor 106 for rotating the bidirectional screw 105 is disposed on the mounting groove 104. Mounting blocks 107 that are slidably connected to the mounting groove 104 are screwed to both sides of the bidirectional screw 105. Monitoring probes 108 are respectively disposed on the two mounting blocks 107. The monitoring probes 108 are screwed to the mounting blocks 107 by fastening bolts 109. The mounting blocks 107 are provided with threaded fastening holes that are screwed to the fastening bolts 109. A controller 203 electrically connected to the monitoring probes 108 and an alarm module electrically connected to the controller 203 are also disposed on the vertical plate 102.

[0023] like Figure 1As shown, the alarm module includes a buzzer 201 and a flashlight 202 mounted on the vertical plate 102. Both the buzzer 201 and the flashlight 202 are electrically connected to the controller 203. The alarm module, including the buzzer 201 and the flashlight 202, can simultaneously emit an audible and visual alarm to remind operators to promptly address the tearing issue. This combined audible and visual approach is suitable for noisy production environments, ensuring that the alarm information is not ignored. The buzzer 201 is a PIEZO TW-BLUE, and the flashlight 202 is an LED warning light, model LXK-12V-R.

[0024] Workers can drive the bidirectional screw 105 to rotate via the drive motor 106 according to the width specifications of the copper foil, thereby moving the two mounting blocks 107 horizontally. The monitoring probes 108 on the mounting blocks 107 are then adjusted to positions corresponding to the two edges of the copper foil. After adjustment, ensure that the monitoring probes 108 can accurately detect the edge status of the copper foil, and then stop the drive motor 106.

[0025] When the copper foil is running on the guide roller, the monitoring probe 108 detects in real time whether there is tearing or displacement on both sides of the edge. The detection signal is transmitted to the controller 203 for analysis and processing. When the controller 203 detects that the copper foil has torn at the edge, the buzzer 201 in the alarm module sounds an alarm; the flashlight 202 in the alarm module flashes at the same time to remind the operator to pay attention. The combination of sound and light ensures that the alarm information can be perceived in time even in noisy environments.

[0026] The monitoring probe 108 can be any type of photoelectric sensor, ultrasonic sensor (model SICK URM37), or laser displacement sensor (model KEYENCE LJ-V7000). In this embodiment, a photoelectric sensor, model E3Z-LS61, is used. When the copper foil is operating normally, the light beam is blocked by the copper foil; if the copper foil is torn at the edge, the light beam is not completely blocked, and the monitoring probe 108 detects the change in the light signal and generates an abnormal signal. The controller 203 is a PLC controller 203-FX3U series.

[0027] The controller 203 is connected to the monitoring probe 108 via a communication interface (such as UART, SPI or I2C). When the monitoring probe 108 detects an abnormal signal, the controller 203 determines whether to trigger the alarm module according to a preset threshold. If it is determined to be a tearing phenomenon, the controller 203 immediately starts the alarm module and records the timestamp and related parameters of the abnormal event.

[0028] A specific embodiment is provided to illustrate the cooperation process between the monitoring probe 108 and the controller 203. For example, assuming the copper foil is 1 meter wide, the monitoring probe 108 is installed 5 millimeters away from the edge of the copper foil. When the copper foil is torn, causing the edge to deviate from the original position by more than 10 millimeters, the monitoring probe 108 detects the signal change and sends the abnormal signal to the controller 203. After receiving the signal, the controller 203 calculates the offset and compares it with the set threshold. After confirming the tearing phenomenon, the alarm module is activated.

[0029] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a rotating shaft 301 is provided at the top of the vertical plate 102, and a connecting sleeve 302 rotatably connected to the rotating shaft 301 is provided on the horizontal plate 103. A connecting bolt 303 is also provided on the connecting sleeve 302, and a connecting hole 304 adapted to the connecting bolt 303 and used for connecting the horizontal plate 103 located on the upper side of the guide roller. When it is necessary to repair the bidirectional screw 105 and the monitoring probe 108, simply separate the connecting bolt 303 from the connecting hole 304, then rotate the horizontal plate 103 90 degrees from the upper side of the guide roller to the outer end of the guide roller, and the bidirectional screw 105 and the monitoring probe 108 can be easily repaired. After the repair is completed, rotate the horizontal plate 103 90 degrees in the opposite direction back to the upper side of the guide roller, and reconnect the connecting bolt 303 to the connecting hole 304.

[0030] According to another embodiment of this utility model, the connecting bolt 303 is a hand-tightening bolt. Users can easily adjust the bolt by hand.

[0031] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the vertical plate 102 is also provided with a support plate 305 for supporting the horizontal plate 103. The lower end of the support plate 305 is fixed to the vertical plate 102, and the upper end of the support plate 305 is in contact with the horizontal plate 103. When the horizontal plate 103 is located above the guide roller, the support plate 305 can provide auxiliary support for the horizontal plate 103, so that the horizontal plate 103 has better stability during operation.

[0032] According to another embodiment of the present invention, such as Figure 2 As shown, a reinforcing plate 306 is also provided between the base 101 and the vertical plate 102, with both ends of the reinforcing plate 306 fixedly connected to the base 101 and the vertical plate 102 respectively. This enhances the connection strength between the vertical plate 102 and the base 101.

[0033] According to another embodiment of the present invention, such as Figure 1As shown, a fixing plate 110 is provided on the base 101. The fixing plate 110 is provided with fixing bolts for fixing to the foil production machine. The fixing plate 110 is also provided with fixing holes 111 for installing the fixing bolts. The driving fixing bolts pass through the fixing holes 111 and thus through the fixing plate 110, and are screwed into the threaded holes on the foil production machine, thereby achieving flexible fixing of the base 101 and the foil production machine.

[0034] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
