[0033] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] The detection device and system of the electrode slitting device in the embodiment of the utility model will be described below with reference to the accompanying drawings. First, the detection device of the electrode slitting device proposed in the embodiment of the utility model will be described with reference to the accompanying drawings.

[0035] Figure 1 The present invention is a block diagram of a detection device for an electrode cutting device according to an embodiment of the present invention.

[0036] like Figure 1 As shown, the electrode slitting device 11 of the embodiment of the utility model includes a plurality of rolled-up electrode sheets 12 , wherein the detection device 10 of the electrode slitting device includes: a device body, a detection module 100 and a communication module 200 .

[0037] The device body is arranged directly above each pole piece 12; a detection module 100 and a communication module 200 are arranged on the device body, wherein the detection module 100 and the communication module 200 are connected, and the detection module 100 detects the reflection signal strength of the pole piece, and when the reflection signal strength is less than the preset strength, the detection module 100 sends the pole piece broken band signal to the host computer 400 through the communication module 200.

[0038] It can be understood that the state of each rolled-up pole piece 12 may include a state where there is no breakage and a state where there is breakage.

[0039] Since the state of each rolled-up pole piece 12 can be represented by the intensity value of the laser signal reflected by the detection module 100, the preset signal strength value refers to the threshold at which the pole piece faces breakage, which can be a threshold calibrated in advance by the user according to the mechanical and physical properties of the pole piece, or a threshold calibrated through a limited number of computer simulations, and is not specifically limited here.

[0040] Therefore, the embodiment of the utility model can convert the status of each electrode piece 12 into a signal strength value through the detection module 100, and use the detection module 100 to monitor the change of the signal strength value of each electrode piece 12 in real time. If the electrode piece signal strength detected by the detection module 100 is less than the preset signal strength, it is judged that the electrode piece 12 is broken. The detection module 100 can send the broken signal to the host computer 400 through the communication module 200, thereby realizing that the electrode slitting device 11 can monitor the broken belt situation of each electrode piece 12 in real time and detect the broken belt of the electrode piece in time, thereby improving the accuracy and timeliness of the device 11 in identifying the broken belt of the electrode piece.

[0041] Optionally, in one embodiment of the present invention, the electrode slitting device 11 includes a roller press or a roller-slitting integrated machine. Thus, the present invention can ensure that the device 11 can accurately and timely identify each electrode segment during the rolling and slitting process in the electrode production process, thereby improving the yield and production capacity in the electrode production process.

[0042] Optionally, in one embodiment of the present invention, Figure 2 As shown, the support member 13 is arranged directly above each electrode piece 12, wherein the device body is mounted on the support member 13, the device body and the electrode piece 12 are arranged oppositely, and the support member 13 is used to support the entire device. Therefore, the support member 13 in the embodiment of the utility model can improve the stability of the detection device 10 of the electrode cutting device.

[0043] Optionally, in an embodiment of the present invention, the detection module 100 is a reflective laser sensor, and the reflection signal is a laser reflection signal.

[0044] For example, in the embodiment of the utility model, the reflective laser sensor can be a reflective laser sensor of the KEYENCE LR-X series, which is not specifically limited here. It should be noted that the reflective laser sensor can convert the detected change in the state of each rolled-up pole piece 12 into a change in voltage / resistance, and use the voltage / resistance value to represent the broken belt condition of the pole piece 12 detected by the reflective laser sensor.

[0045] The embodiment of the utility model can use a reflective laser sensor to use voltage / resistance value to indicate the state of each rolled-up electrode piece 12, and can more intuitively indicate the change in the state of each rolled-up electrode piece 12, thereby clearly indicating whether each electrode piece is broken, so that the electrode slitting equipment 11 can accurately and conveniently detect the breakage of the electrode piece during the production process.

[0046] Optionally, in one embodiment of the present invention, Figure 2 As shown, the reflective laser sensor includes: a laser light source 101 and an optical lens 102, the laser light source 101 emits laser to the pole piece 12 through the optical lens 102; a detector 103 for detecting the intensity of the laser reflection signal generated by the pole piece 12 reflecting the laser; a signal processor 104 connected to the detector 103, which generates a band break signal of the pole piece when the intensity of the reflection signal is less than a preset intensity; and an output interface 105 connected to the communication module 200, which outputs the band break signal.

[0047] Among them, combined Figure 3 As shown, Figure 3 1 is a schematic diagram of the structure of a detection device 10 of an electrode slitting device according to an embodiment of the utility model. In the embodiment of the utility model, each rolled-up pole piece 12 is wound around a roller of the device 11, which can enhance the tension of the pole piece 12 when it is rolled up. A reflective laser sensor is installed directly above each pole piece 12, wherein the output interface 105 in the reflective laser sensor can send a broken belt signal to the host computer 400 through the communication module 200.

[0048] The host computer 400 refers to a computer or a single-chip microcomputer that can be directly connected to the machine, and can be various programmable chips such as PLC (Programmable Logic Controller), ARM (Advanced RISC Machine), etc. The embodiment of the utility model takes the PLC device as an example and is not specifically limited here.

[0049] Therefore, in the embodiment of the utility model, the detection module 100 can send the detected broken tape signal to the host computer 400 through the output interface 105, thereby improving the convenience of the detection device 10 of the electrode slitting equipment sending the broken tape signal to the host computer 400.

[0050] Optionally, in one embodiment of the present invention, Figure 2 As shown, the communication module 200 includes a wired communication device 201 and / or a wireless communication device 202 .

[0051] It should be noted that the wired communication device 201 may include an optical fiber communication device and / or a cable communication device, etc.; the wireless communication device 202 may include a Bluetooth wireless communication device and / or a UWB (Ultra Wide Band) wireless communication device, etc. The specific setting of the communication module 200 is operated by technical personnel in this field according to actual conditions and is not specifically limited here.

[0052] Optionally, in one embodiment of the present invention, the communication module 200 communicates with the host computer 400 by wire and / or wirelessly.

[0053] It can be understood that wired communication refers to the process in which the detection device 10 of the electrode cutting equipment and the PLC device use the wired communication device 201 to exchange data; wireless communication refers to the process in which the detection device 10 of the electrode cutting equipment and the PLC device use the wireless communication device 202 to exchange data.

[0054] Specifically, when any of the rolled pole pieces 12 is found to be broken, the reflective laser sensor of the embodiment of the utility model can perform wired communication with the PLC device through the wired communication device 201 or wireless communication with the PLC device through the wireless communication device 202, or the wired communication device 201 performs wired communication with the PLC device and the wireless communication device 202 performs wireless communication with the PLC device. The specific settings of the wired communication device 201 and the wireless communication device 202 are operated by those skilled in the art according to actual conditions and are not specifically limited here.

[0055] Therefore, the embodiment of the utility model can be applied to a variety of scenarios. By being compatible with the wired communication device 201 and the wireless communication device 202, it solves the problem that the wiring of pure wired communication is difficult, and pure wireless communication cannot communicate normally when the wireless signal is poor, thus affecting the normal operation of the device 10. Among them, by using wireless communication transmission, the transmission rate is higher and the data carrying capacity is large, which solves the problem of installation and maintenance of communication lines for wired communication. When the wireless communication is interfered, it can automatically switch to wired communication to ensure the reliability and stability of the communication between the detection device 10 of the electrode cutting equipment and the PLC equipment.

[0056] The working principle of the detection device 10 for the electrode cutting device will be described in detail below with a specific embodiment. Figure 4 As shown, the details are as follows:

[0057] (1) The reflective laser sensor sends the laser light source 101 to each rolled pole piece 12 through the optical lens 102. The pole piece 12 reflects the laser light source 101 to the reflective laser sensor. The reflective laser sensor detects the intensity value of the laser reflection signal of the laser light source 101 reflected by the pole piece through the detector 103.

[0058] (2) If the reflected signal strength value of the pole piece 12 is less than the preset signal strength threshold, a pole piece broken signal is generated by the signal processor 104, and the output interface 105 sends the broken signal to the communication module 200, and the communication module transmits the broken signal to the PLC device through wired communication and / or wireless communication;

[0059] (3) If the reflection signal strength value of the electrode piece 12 is greater than the preset signal strength threshold, the electrode cutting device 11 operates normally.

[0060] Therefore, the embodiment of the utility model can determine the state of each wound pole piece 12 by judging in real time whether the reflection signal strength value in the production process of each pole piece is less than the preset reflection signal strength threshold, so as to accurately determine whether each wound pole piece 12 is broken, and send the broken belt signal to the PLC device in time.

[0061] In summary, according to the detection device of the electrode slitting equipment proposed in the embodiment of the utility model, the state of each electrode piece can be converted into a signal strength value through a reflective laser sensor, and the reflective laser sensor can be used to monitor the change of the signal strength value of each wound electrode piece in real time. If the signal intensity reflected by the electrode piece detected by the reflective sensor is less than the preset signal strength value, the reflective laser sensor can determine that the electrode piece is broken, and can send the broken band signal to the host computer through the communication module, and the communication module and the host computer can realize multiple communication channels for communication, thereby realizing that the electrode slitting equipment can monitor the broken band situation of each wound electrode piece in real time and stably and detect the broken band of the electrode piece in time, thereby improving the accuracy, timeliness and reliability of the electrode slitting equipment in identifying the broken band of the electrode piece.

[0062] The utility model also provides a detection system comprising the detection device of the electrode cutting equipment.

[0063] like Figure 5 As shown, the detection system 30 of the detection device of the electrode slitting equipment includes: an electrode slitting equipment 11 including a plurality of rolled electrode sheets 12; the detection device 10 of the electrode slitting equipment mentioned in the above embodiment; a host computer 400 communicating with the detection device 10 of the electrode slitting equipment, the host computer 400 is connected to the electrode slitting equipment 11, and controls the electrode slitting equipment 11 to stop according to the broken belt signal sent by the detection device 10 of the electrode slitting equipment.

[0064] It can be understood that in the embodiment of the utility model, the host computer 400 can be connected to the electrode slitting device 11 through the host computer software development. It should be noted that the host computer software development refers to the development and service of the host computer application software, that is, through the host computer software application, a seamless connection from online to offline is achieved.

[0065] The detection system 30 of the electrode slitting equipment of the embodiment of the utility model adopts the detection device 10 of the electrode slitting equipment of the above-mentioned embodiment. After the host computer 400 receives the broken tape signal sent by the detection device 10, the host computer 400 can timely control the shutdown of the electrode slitting equipment 11 through the host computer software, thereby avoiding the scrapping of the electrode due to the accumulation of broken tapes of the electrode pieces, and improving the yield and production capacity in the electrode production process.

[0066] Optionally, in one embodiment of the present invention, Figure 6 As shown, the detection system 30 of the electrode slitting device also includes: an alarm component 500 connected to the host computer 400; the host computer 400 generates an alarm signal when controlling the electrode slitting device 11 to stop; and the alarm component 500 alarms according to the alarm signal.

[0067] It can be understood that the alarm component 500 refers to an external component plugged into the host computer 400, which is used to issue an alarm based on the alarm signal received by the host computer 400.

[0068] In the embodiment of the utility model, while the upper computer 400 controls the electrode slitting equipment 11 to shut down, the upper computer 400 can also add and plug in a large number of peripheral components to form an alarm component 500 to prompt the staff to promptly reconnect the broken pole pieces to avoid the pole pieces being scrapped due to the accumulation of broken pole pieces.

[0069] Optionally, in one embodiment of the present invention, Figure 6 As shown, the alarm component 500 includes: an optical alarm component 501 and / or an acoustic alarm component 502.

[0070] Among them, the optical alarm component 501 can be an LED (light emitting diode) display screen, a liquid crystal display screen or other display devices with optical display function connected to the host computer 400, and the acoustic alarm component 502 can be a warning speaker, alarm, buzzer or other alarm device with acoustic alarm function connected to the host computer 400, and no specific limitation is made here.

[0071] Specifically, when any of the rolled pole pieces 12 is found to be broken, the embodiment of the utility model can make an optical alarm through the optical alarm component 501, or make an acoustic alarm through the acoustic alarm component 502, or the optical alarm component 501 makes an optical alarm and the acoustic alarm component 502 makes an acoustic alarm. The optical alarm can remind the staff by flashing an LED or displaying "Pole piece broken, please connect!" on the LCD screen; the acoustic alarm can remind the staff by making a "beep beep" sound from the alarm, or by a voice alarm "Pole piece broken, please connect!" The specific setting of the alarm component 500 is operated by those skilled in the art according to the actual situation and is not specifically limited here.

[0072] Therefore, in the embodiment of the utility model, when the electrode slitting equipment 11 is running, when the detection device 10 detects that any of the rolled-up electrode pieces 12 is broken, the multi-directional tape splicing reminder of the host computer 400 can promptly remind the staff to perform the electrode tape splicing operation and issue an alarm in real time, thereby avoiding the scrapping of the electrode pieces due to the accumulation of broken electrode pieces, and further improving the yield and production capacity of the electrode pieces in the production process.

[0073] Specifically, in the embodiment of the present utility model, combined with Figure 7 As shown, the working principle of the detection system 30 of the electrode cutting device of the embodiment of the utility model is described in detail with a specific embodiment.

[0074] It should be noted that, in the embodiment of the present utility model, the host computer 400 may be a PLC device. Figure 7 As shown, when there are multiple pole pieces during winding, a Keyence LR-X series reflective laser sensor is arranged directly above each pole piece 12 of the winding. When the electrode slitting equipment 11 is operating normally, the pole piece tape is in a taut state, and the pole piece can reflect the laser to the reflective laser sensor. After the sensor receives the laser reflected by the pole piece, it compares it with the set threshold value. When it is greater than the threshold value, it is judged to be operating normally, and the PLC device has no alarm; when the pole piece is broken, the pole piece cannot reflect the laser, and the sensor cannot receive the laser, the actual detection value is less than the set threshold value, and the sensor transmits a broken tape signal to the communication module 200, and the communication module 200 transmits the broken tape signal to the PLC device. The PLC device issues a real-time alarm and promptly controls the electrode slitting equipment 11 to shut down. At this time, the operator can immediately connect the pole piece to avoid the pole piece being scrapped due to the accumulation of broken tapes, thereby improving the yield and production capacity of the pole piece in the production process.

[0075] In summary, according to the detection system of the electrode slitting equipment proposed in the embodiment of the utility model, the detection device of the electrode slitting equipment mentioned above is adopted. After the upper computer receives the broken tape signal sent by the communication module, the upper computer can control the electrode slitting equipment to stop in time, and issue an alarm in real time to warn the staff to connect the tape in time, thereby avoiding the scrapping of the electrode due to the accumulation of broken tapes, and improving the yield and production capacity in the electrode production process.
