[0049] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] To facilitate understanding, the following will be combined with... Figure 1 The application scenarios applicable to the embodiments of this application will be described.

[0053] Figure 1 This is a schematic diagram illustrating an application scenario of a broken needle detection device provided in an embodiment of this application. Please refer to... Figure 1The glove-making machine can be equipped with a front needle plate, a rear needle plate, and a broken needle detection device. Depending on user needs, a certain number of needles can be installed on the front needle plate and a certain number on the rear needle plate, with a certain spacing between adjacent needles. When the glove-making machine is knitting gloves, the front and rear needle plates are in a high-speed motion. The broken needle detection device can detect the number of needles installed on the front and rear needle plates and the spacing between adjacent needles, and determine whether there are any broken needles on the front and rear needle plates.

[0054] In related technologies, existing solutions for needle breakage detection in glove machines connect the front and rear machine heads to the needle breakage detection equipment via highly flexible cables. However, since the front and rear machine heads are constantly in a high-speed reciprocating motion, the highly flexible cables are prone to breakage and need to be replaced frequently, resulting in a decrease in production efficiency.

[0055] To address the aforementioned problems, the inventors, during their research on needle breakage detection methods for glove machines, discovered that wireless networking can be used to enable communication between wireless terminals and a coordinator. One wireless terminal and one limit switch can be installed on each of the front and rear needle plates of the glove machine. Each wireless terminal is connected to its respective limit switch. The limit switch wakes up the wireless terminal when the head reaches a fixed position. The two wireless terminals then network with the coordinator. After networking, each wireless terminal controls its connected needle-measuring sensor to measure the number of needles on the front and rear needle plates, as well as the spacing between adjacent needles. The wireless terminals can then wirelessly transmit the measured needle count and spacing to the coordinator. The coordinator sends the received needle count and spacing to a processor. The processor uses these data to determine if a needle breakage has occurred. If a needle breakage is detected, a stop command is sent to the glove machine's controller to stop the machine. Based on this, this solution proposes a broken needle detection device, system, and method, which uses a wireless networking approach to solve the problem of easy breakage of highly flexible cables in existing solutions and improve production efficiency.

[0056] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; for the same or similar content, the description will not be repeated in different embodiments.

The first needle sensor 11 is used to measure the first parameter data of the front needle plate 33 of the glove machine 30. The first parameter data includes: the number of needles on the front needle plate 33 and the spacing between adjacent needles.

[0060] The second needle sensor 12 is disposed on the rear head 32 of the glove machine 30 and connected to the second wireless terminal 14. The second needle sensor 12 is used to measure the second parameter data of the rear needle plate 34 of the glove machine 30. The second parameter data includes the number of needles on the rear needle plate 34 and the spacing between adjacent needles.

[0061] The coordinator 15 is connected to the first wireless terminal 13 and the second wireless terminal 14 via wireless communication, and the coordinator 15 is also connected to the processor 16.

[0062] The first wireless terminal 13 is used to wirelessly transmit the first parameter data detected by the first probe sensor 11 to the coordinator 15, and the second wireless terminal 14 is used to wirelessly transmit the second parameter data detected by the second probe sensor 12 to the coordinator 15.

[0063] Coordinator 15 is used to send the first parameter data and the second parameter data to processor 16;

[0064] In one alternative implementation, the coordinator 15 and the processor 16 may use an asynchronous serial communication method, UART (Universal Asynchronous Receiver / Transmitter), to transmit data.

[0065] The processor 16 is used to determine whether there is a broken needle in the glove machine 30 based on the first parameter data and / or the second parameter data.

[0066] The broken needle detection device provided in this application includes a first needle sensor, a second needle sensor, a first wireless terminal, a second wireless terminal, a coordinator, and a processor. The first needle sensor measures first parameter data of the front needle plate of the glove machine, and the second needle sensor measures second parameter data of the rear needle plate of the glove machine. The first parameter data includes the number of needles on the front needle plate and the spacing between adjacent needles; the second parameter data includes the number of needles on the rear needle plate and the spacing between adjacent needles. The first wireless terminal can send the first parameter data measured by the first needle sensor to the coordinator, and the second wireless terminal can send the second parameter data measured by the second needle sensor to the coordinator. The coordinator can then send the first and second parameter data to the processor, which determines whether the glove machine has broken needles based on the first and second parameter data. This device can acquire the first and second parameter data through a wireless network between the wireless terminals and the coordinator, determine whether the glove machine has broken needles, and thus control the operation of the glove machine, solving the problem of easily broken high-flexibility cables in existing solutions and improving production efficiency.

[0067] Figure 3 This is a schematic diagram of a second embodiment of a broken needle detection device provided in this application. Figure 2 Based on the illustrated embodiments, please refer to Figure 3 The broken needle detection device 10 also includes a first limit switch 17 and a second limit switch 18;

[0068] The first limit switch 17 is located on the side of the front head 31 and connected to the first wireless terminal 13. The first limit switch 17 is used to trigger the first wireless terminal 13 to control the first needle sensor 11 to measure the first parameter data of the front needle plate 33 after the front head 31 moves to the first designated position.

[0069] The second limit switch 18 is located on the side of the rear head 32 and connected to the second wireless terminal 14. The second limit switch 18 is used to trigger the second wireless terminal 14 to control the second needle sensor 12 to measure the second parameter data of the rear needle plate 34 after the rear head 32 moves to the second designated position.

[0070] Optionally, a limit switch, also known as a position switch, is a commonly used low-current control electrical device. It can activate the circuit by actuating the contacts of moving parts in the production machinery, thereby triggering the wireless terminal to control the needle sensor to measure the parameter data of the needle plate. It resets when the glove machine stops running. For example, a first designated position can be selected in the movement direction of the front head 31. A stop lever can be set at the first designated position. When the first limit switch 17 moves to the first designated position, the contact of the first limit switch 17 touches the stop lever to activate the circuit.

A second designated position can be selected in the movement direction of the rear head 32. A stop lever can be set at the second designated position. When the second limit switch 18 moves to the second designated position, the contact of the second limit switch 18 touches the stop lever to activate the circuit. At this time, the second wireless terminal 14 is triggered to control the second needle sensor 12 to measure the second parameter data of the rear needle plate 34.

[0071] Optionally, the limit switch can also be a proximity switch without mechanical contacts, which has the function of a limit switch. When the proximity switch approaches a certain distance, it sends an action signal to trigger the wireless terminal to control the needle sensor to measure the parameter data of the needle plate. No mechanical external force is required, and it resets when the glove machine stops running.

[0073] The second wireless terminal 14 is connected to the second probe sensor 12 via a wired connection, and the second wireless terminal 14 is used to power the second probe sensor 12.

This device can detect whether a broken needle exists in the glove machine during operation by setting the limit switch to trigger the wireless terminal to control the needle sensor to measure the needle plate parameter data, thereby controlling the operation of the glove machine.

[0075] Figure 4 This is a schematic diagram of a third embodiment of a broken needle detection device provided in this application. Please refer to... Figure 4 The broken needle detection device 10 also includes: a first rechargeable battery 19 and a second rechargeable battery 20;

[0076] The first rechargeable battery 19 is connected to the first wireless terminal 13 and is used to power the first wireless terminal 13.

[0077] The second rechargeable battery 20 is connected to the second wireless terminal 14 and is used to power the second wireless terminal 14.

[0080] Figure 5 This is a schematic diagram of a fourth embodiment of a broken needle detection device provided in this application. Please refer to... Figure 5 The broken needle detection device provided in this embodiment further refines the first wireless terminal 13 and the second wireless terminal 14 based on the broken needle detection device provided in any of the above embodiments.

[0081] The first wireless terminal 13 includes a first power module 131 and a first communication module 132 connected to the first power module 131.

This solves the problem of easy breakage of highly flexible cables in existing solutions and improves production efficiency.

[0086] To further explain the application principles of wireless terminals, the following will be combined with... Figure 6 The following is an illustration of the principle of a wireless terminal application.

[0087] Figure 6 This is a schematic diagram illustrating the application principle of a wireless terminal provided in an embodiment of this application. Please refer to... Figure 6 The wireless terminal 40 can be charged by the lithium battery 42, which in turn can be charged by the charging circuit 41. For example, the power supply of the glove machine can charge the lithium battery 42 through the charging circuit 41, and the charged lithium battery 42 can then supply power to the wireless terminal 40.

The limit switch 46 and the probe sensor 47 are connected to the wireless chip. The wireless chip can be any of the following wireless communication methods: Zig-bee, Bluetooth, and Sub-G.

[0089] The application principle of the wireless terminal provided in this application embodiment is the same as the implementation principle of the wireless terminal in the above-mentioned broken needle detection device, and will not be repeated here.

[0090] In one specific implementation, the broken needle detection device provided in any of the above embodiments can detect whether there are broken needles on the front needle plate and the rear needle plate in real time without affecting the normal knitting efficiency of the glove machine. It can also detect whether there are broken needles on the front needle plate and the rear needle plate when a glove is finished and dropped.

[0091] Figure 7 This is a schematic diagram of a broken needle detection system provided in an embodiment of this application. Please refer to [link / reference]. Figure 7The broken needle detection system 50 includes a broken needle detection device 51 and a glove machine 52. The broken needle detection device 51 can determine whether there is a broken needle in the glove machine 52 while it is running. If a broken needle is detected, it sends a stop command to the controller 521 of the glove machine 52 to stop the glove machine 52.

[0092] To further illustrate, the process by which the processor in the broken needle detection device determines whether a glove machine has broken needles based on the first parameter data and / or the second parameter data, combined with... Figure 8 The following is an example of a broken needle detection method illustrated in the diagram.

[0093] Figure 8 This is a schematic flowchart illustrating a broken needle detection method according to an embodiment of this application. Please refer to... Figure 8 This broken needle detection method is applied in the processor of a broken needle detection device, and the method includes:

[0094] S101, Receive the first parameter data and the second parameter data sent by the coordinator.

[0095] During operation, the processor can receive first parameter data and second parameter data sent by the coordinator. The first parameter data includes the number of needles on the front needle plate of the glove machine and the spacing between adjacent needles, while the second parameter data includes the number of needles on the rear needle plate of the glove machine and the spacing between adjacent needles.

[0096] For example, during the operation of the glove machine, the processor can receive first parameter data and second parameter data sent by the coordinator. The first parameter data includes: the number of needles on the front needle plate of the glove machine is 4; the distance between needle 1 and needle 2 is 5 mm; the distance between needle 2 and needle 3 is 5 mm; and the distance between needle 3 and needle 5 is 10 mm. The second parameter data includes: the number of needles on the rear needle plate of the glove machine is 5; the distance between needle 1 and needle 2 is 5 mm; the distance between needle 2 and needle 3 is 5 mm; the distance between needle 3 and needle 4 is 5 mm; and the distance between needle 4 and needle 5 is 5 mm.

[0097] S102. Determine whether the glove machine has broken needles based on the first parameter data and / or the second parameter data.

[0098] After receiving the first parameter data and / or the second parameter data, the processor can determine whether the glove machine has broken needles based on the first parameter data and / or the second parameter data. Specifically, the first parameter data can be compared with the preset total number of needles on the front needle plate and the spacing between adjacent needles to determine if there are broken needles on the front needle plate; the second parameter data can be compared with the preset total number of needles on the rear needle plate and the spacing between adjacent needles to determine if there are broken needles on the rear needle plate. If broken needles are present on both the front and / or rear needle plates, the glove machine is determined to have broken needles; if neither the front nor rear needle plates have broken needles, the glove machine is determined not to have broken needles.

[0099] In one specific implementation, when a broken needle is determined to exist, the specific location of the broken needle can be determined based on a first broken needle parameter and / or a second broken needle parameter. For example, if a broken needle is determined to exist on the front needle plate based on the first parameter data, the location of the broken needle on the front needle plate can also be determined based on the first parameter data. Alternatively, if a broken needle is determined to exist on the rear needle plate based on the second parameter data, the location of the broken needle on the rear needle plate can also be determined based on the second parameter data.

[0100] In one optional implementation, the processor presets the total number of needles on the front needle plate and the spacing between adjacent needles, as well as the total number of needles on the rear needle plate and the spacing between adjacent needles. For example, the processor presets the total number of needles on the front needle plate to be 5 and the spacing between adjacent needles to be 5mm, as well as the total number of needles on the rear needle plate to be 5 and the spacing between adjacent needles to be 5mm.

[0101] For example, the processor is preset with a total of 5 needles on the front needle plate and a spacing of 5mm between adjacent needles, and a total of 5 needles on the rear needle plate and a spacing of 5mm between adjacent needles. Based on the fact that the number of needles on the front needle plate of the glove machine is 4, which is different from the preset total of 5 needles, and the spacing between needles 3 and 5 is 10mm, which is different from the preset spacing of 5mm between adjacent needles, it can be determined that there is a broken needle on the front needle plate, and the broken needle is located at the position of needle 4. Based on the fact that the number of needles on the rear needle plate of the glove machine is 5, which is the same as the preset total of 5 needles, and the needle spacing is the same as the preset spacing of 5mm between adjacent needles, it can be determined that there is no broken needle on the rear needle plate.

[0102] In one specific implementation, when the processor determines that the glove machine has a broken needle, it can send a stop command to the glove machine's controller to control the glove machine to stop.

[0103] In this embodiment, the processor can receive first parameter data and second parameter data sent by the coordinator. Based on the first parameter data, it determines whether there is a broken needle on the front needle plate, and based on the second parameter data, it determines whether there is a broken needle on the rear needle plate. If a broken needle is found on the front needle plate and / or the rear needle plate, it is determined that the glove machine has a broken needle condition, and the location of the broken needle can also be determined. In the above process, the processor can determine whether the glove machine has a broken needle condition based on the received parameter data. If the processor determines that the glove machine has a broken needle condition, it can further send a stop command to the glove machine's controller to stop the glove machine, thereby preventing the production of defective gloves and avoiding losses to the company.

[0104] exist Figure 8 Based on the illustrated embodiment, the following, in conjunction with Figure 9 The above-mentioned needle breakage detection method will be further explained in detail.

[0105] Figure 9 This is a flowchart illustrating a second embodiment of a needle breakage detection method provided in this application. Please refer to... Figure 9 The method includes:

[0106] S201, Receive the first parameter data and the second parameter data sent by the coordinator.

[0107] For example, the processor can receive first parameter data and second parameter data sent by the receiving coordinator. The first parameter data includes: the number of needles on the front needle plate of the glove machine is 3, the distance between needle 1 and needle 3 is 10mm, and the distance between needle 3 and needle 5 is 10mm; the second parameter data includes: the number of needles on the front needle plate of the glove machine is 4, the distance between needle 1 and needle 2 is 5mm, the distance between needle 2 and needle 3 is 5mm, and the distance between needle 3 and needle 5 is 10mm.

[0108] S202. Compare the first parameter data with the preset total number of needles on the front needle plate and the spacing between adjacent needles to determine whether there are broken needles on the front needle plate.

[0109] After receiving the first parameter data sent by the coordinator, the processor can compare the number of needles on the front needle plate of the glove machine and the spacing between adjacent needles included in the first parameter data with the preset total number of needles on the front needle plate and the spacing between adjacent needles to determine whether there are broken needles on the front needle plate.

[0110] For example, if the processor presets a total of 5 needles on the front needle plate and a spacing of 5mm between adjacent needles, after receiving the first parameter data sent by the coordinator, the processor can determine that there are broken needles on the front needle plate, and the broken needles are located at the positions of needles 2 and 4, based on the following: the number of needles on the front needle plate of the glove machine is 3, which is different from the preset total number of needles on the front needle plate of 5; the spacing between needles 1 and 3 is 10mm, which is different from the preset spacing between adjacent needles of 5mm; and the spacing between needles 3 and 5 is 10mm, which is different from the preset spacing between adjacent needles of 5mm.

[0111] S203. Compare the second parameter data with the preset total number of needles on the back needle plate and the spacing between adjacent needles to determine whether there are broken needles on the back needle plate.

[0112] After receiving the second parameter data sent by the coordinator, the processor can compare the number of needles on the front needle plate of the glove machine and the spacing between adjacent needles included in the second parameter data with the preset total number of needles on the rear needle plate and the spacing between adjacent needles to determine whether there are broken needles on the rear needle plate.

[0113] For example, if the processor presets a total of 5 needles on the back needle plate and a spacing of 5mm between adjacent needles, after receiving the second parameter data sent by the coordinator, the processor can determine that there is a broken needle on the back needle plate, and the broken needle location is the position of needle 4, based on the fact that the number of needles on the front needle plate of the glove machine is 4, which is different from the preset total number of needles on the front needle plate of 5, and the spacing between needles 3 and 5 is 10mm, which is different from the preset spacing between adjacent needles of 5mm.

[0114] S204. If there are broken needles on the front needle plate and / or on the rear needle plate, then the glove machine is confirmed to have broken needles.

[0115] When the processor determines, based on the first parameter data and / or the second parameter data, that there is a broken needle on the front needle plate and / or the rear needle plate, it can determine that there is a broken needle in the glove machine.

[0116] For example, if the processor determines that there is a broken needle on the front needle plate based on the first parameter data, and determines that there is a broken needle on the rear needle plate based on the second parameter data, then it can determine that there is a broken needle situation in the glove machine.

[0117] S205. If there are no broken needles on the front needle plate and no broken needles on the rear needle plate, then it is determined that there are no broken needles in the glove machine.

[0118] For example, if the processor determines that there are no broken needles on the front needle plate and the rear needle plate based on the first parameter data and the second parameter data, it can determine that there are broken needles in the glove machine.

[0119] S206. If it is determined that there is a broken needle in the glove machine, a stop command is sent to the controller of the glove machine to control the glove machine to stop.

[0120] Once the processor detects a broken needle in the glove, it must immediately send a stop command to the glove machine's controller to halt operation and prevent the production of defective gloves.

[0121] In this embodiment, after receiving the first parameter data and the second parameter data sent by the coordinator, the processor can compare the first parameter data with the preset total number of needles on the front needle plate and the spacing between adjacent needles to determine whether there are broken needles on the front needle plate. It then compares the second parameter data with the preset total number of needles on the rear needle plate and the spacing between adjacent needles to determine whether there are broken needles on the rear needle plate. If broken needles are found on both the front and rear needle plates, the glove machine is determined to have broken needles. Conversely, if neither the front nor rear needle plates have broken needles, the glove machine is determined not to have broken needles. If a broken needle situation is determined, a stop command is sent to the glove machine's controller to stop the machine and prevent a large batch of gloves from being damaged due to delayed stopping.
