Description

Technical Field

[0001] This application relates to the field of acupuncture technology, and in particular to a method for preparing a preform, an acupuncture monitoring system, and electronic equipment. Background Technology

[0002] Currently, carbon fiber crucible preforms are mainly produced using carbon fiber needle punching machines. During production, a preform mold of the desired product shape needs to be installed on the carbon fiber needle punching machine. Then, carbon fiber material is laid on the preform mold, and the laid carbon fiber material is needle punched. After completion, carbon fiber material is laid again and needle punching is repeated. This can be understood as a process of repeated needle punching after each laying of carbon fiber material.

[0003] In actual product manufacturing, the depth to which the needle tip of a carbon fiber needle punching machine penetrates the product has strict process requirements. Too deep or too shallow a penetration depth will affect the quality of the final product; therefore, standard control of the penetration depth is necessary. Typically, the needle plate of a carbon fiber needle punching machine performs a fixed up-and-down stroke. The needle penetration depth is controlled by adjusting the mold height. Since the product shape continuously increases throughout the processing, the mold height needs to be determined through manual observation or relevant sensors. Finally, the mold height is adjusted based on the feedback results.

[0004] However, existing methods for determining mold height using manual observation or related sensors are inaccurate. Manual observation has significant errors, and the use of sensors, such as laser or infrared sensors, is prone to misjudgment due to the presence of burrs and rough edges on the carbon fiber material laid on the mold, and the fact that the carbon fiber material is in a flexible state before needle punching. This makes it impossible to accurately determine the needle depth and meet actual production needs. Therefore, existing carbon fiber needle punching machines cannot accurately determine the needle depth, cannot replace broken needles in a timely manner, and cannot promptly assess the lifespan of the needles, thus affecting the stability and reliability of the preform. Summary of the Invention

[0005] The purpose of this application is to provide a method for preparing a preform, a needle-punching monitoring system, and electronic equipment to solve the problems of existing carbon fiber needle-punching machines being unable to accurately determine the needle depth, unable to replace broken needles in time, and unable to timely assess the lifespan of needles, thus affecting the stability and reliability of the prepared preform.

[0006] In a first aspect, this application provides a method for preparing a preform, comprising:

[0007] Obtain multiple resistance values ​​corresponding to a preset number of needles;

[0008] When at least one of the multiple resistance values ​​changes from insulation state data to conduction state data, the height of the preform mold is adjusted according to the preset needle penetration depth.

[0009] Based on the adjusted height of the preform mold, the depth to which the piercing needle penetrates the preform mold reaches the preset piercing depth, so as to prepare the target preform.

[0010] The preform preparation method provided in this application obtains multiple resistance values ​​corresponding to a preset number of needles. When at least one of the multiple resistance values ​​changes from an insulation state to a conduction state, that is, when a needle contacts the preform mold, the height of the preform mold is adjusted according to a preset needle penetration depth. Based on the adjusted preform mold height, the depth to which the corresponding needle penetrates the preform mold reaches the preset needle penetration depth, thereby preparing the target preform. This method can achieve precise control of the needle penetration depth, improving the reliability and stability of the target preform preparation.

[0011] Secondly, this application provides a method for preparing a preform, comprising:

[0012] Obtain multiple resistance values ​​corresponding to a preset number of needles;

[0013] During the preparation of the target preform, the multiple resistance values ​​are divided into a set of resistance values ​​in the conducting state and a set of resistance values ​​in the insulating state based on a preset classification method;

[0014] Multiple resistance values ​​in the set of on-state resistance values ​​are determined as usage status data;

[0015] For all needles in the usage status data, the number of times they are used is accumulated and incremented by one from the historical usage count.

[0016] If the number of times each needle is used is greater than or equal to a preset usage threshold, the corresponding needle is determined to be in a state to be replaced.

[0017] Control the replacement of the needle in the state to be replaced.

[0018] The preform preparation method provided in this application embodiment can obtain multiple resistance values ​​corresponding to a preset number of needles. During the preparation of the target preform, the multiple resistance values ​​are divided into a set of resistance values ​​in a conducting state and a set of resistance values ​​in an insulating state based on a preset classification method. The multiple resistance values ​​in the set of resistance values ​​in the conducting state are determined as usage status data. The number of times each needle is used corresponding to the usage status data is accumulated and incremented by one based on the historical usage count. If the number of times each needle is used is greater than or equal to a preset usage count threshold, the corresponding needle is determined to be in a replacement-waiting state. The needles in the replacement-waiting state are controlled to be replaced, avoiding needle waste and overuse. The lifespan assessment of the needles is accurately completed, ensuring the reliability and stability of the needles. Furthermore, the reliability and stability of the prepared target preform can be guaranteed.

[0019] Thirdly, this application provides a method for preparing a preform, comprising:

[0020] Obtain multiple resistance values ​​corresponding to a preset number of needles;

[0021] During the preparation of the target preform, multiple resistance values ​​are classified into a set of resistance values ​​in the conducting state and a set of resistance values ​​in the insulating state based on a preset classification method;

[0022] The set of needles whose needle position information is located in the set of conductive state resistance values ​​and whose insulation state resistance values ​​are in the set of insulating state resistance values ​​are the set of needles to be detected.

[0023] Identify the target broken needle in the set of needles to be tested;

[0024] Control the replacement of the target broken needle.

[0025] The preform preparation method provided in this application embodiment can obtain multiple resistance values ​​corresponding to a preset number of needles. During the preparation of the target preform, the multiple resistance values ​​are divided into a set of conducting state resistance values ​​and a set of insulating state resistance values ​​based on a preset classification method. Multiple needles in the set of insulating state resistance values ​​whose needle position information is located between the needles in the set of conducting state resistance values ​​are identified as the set of needles to be tested. The target broken needles in the set of needles to be tested are identified, and the target broken needles are controlled to be replaced. This allows for timely replacement of broken needles, improving the reliability and stability of the preparation of the target preform.

[0026] In one possible implementation, determining the target broken needle in the set of needles to be detected includes:

[0027] Update the current resistance values ​​of all needles corresponding to the set of needles to be detected;

[0028] If the current resistance value is the insulation resistance value, then the needle corresponding to the current resistance value is determined to be the target broken needle.

[0029] Fourthly, this application also provides an acupuncture monitoring system, comprising:

[0030] The preform mold, the needle punching device, the monitoring unit and the control unit respectively connected to the needle punching device, wherein the needle punching device is used to perform needle punching treatment on the preform mold;

[0031] The acupuncture device includes a needle plate, a needle unit, and a connecting conductive wire unit connected in sequence.

[0032] The monitoring unit is used to control the connecting conductive wire unit to perform periodic scanning processing on the needle unit, and to obtain the conduction status data of the needle unit in each period.

[0033] The control unit is used to acquire the conduction status data corresponding to the needle unit transmitted by the monitoring unit, which changes from insulation status data to conduction status data.

[0034] In summary, the preform preparation method provided in this application can obtain multiple resistance values ​​corresponding to a preset number of needles. During the preparation of the target preform, multiple resistance values ​​are divided into a set of conducting resistance values ​​and a set of insulating resistance values ​​based on a preset classification method. Multiple needles in the set of insulating resistance values ​​whose needle position information is located between the needles in the set of conducting resistance values ​​are identified as the set of needles to be tested. Target broken needles in the set of needles to be tested are identified, and the target broken needles are controlled to be replaced. This allows for timely replacement of broken needles, improving the reliability and stability of the preparation of the target preform.

[0035] In one possible implementation, the needle unit includes a preset number of needles spaced apart, and the connecting conductive wire unit includes a plurality of connecting conductive wires with the same number of needles as the needle unit. One end of the preset number of connecting conductive wires is connected to the corresponding needles one by one, and the other end is connected to the monitoring unit. The monitoring unit is connected to the control unit.

[0036] The contact portions of a predetermined number of needles and the needle plate in the needle unit are insulated from each other.

[0037] In one possible implementation, the control unit includes a data statistical processing module and a device control module connected in sequence; wherein the data statistical processing module and the monitoring unit are connected.

[0038] The device control module is used to control the monitoring unit to perform periodic scanning processing on the needle unit through the connecting conductive wire unit;

[0039] The data statistics processing module is used to obtain the conduction status data of each needle corresponding to each connecting conductive line in each cycle transmitted by the monitoring unit.

[0040] The device control module is further configured to, when the monitoring unit transmits at least one of the needles corresponding to the conduction state data which changes from insulation state data to conduction state data, adjust the height of the preform mold according to a preset needle penetration depth, so as to control the depth to which the needle penetrates the preform mold to reach the preset needle penetration depth.

[0041] In one possible implementation, the data statistics processing module is further configured to identify all the needles in the conduction state as being in use state data.

[0042] The device control module is also used to accumulate and increment the historical usage count of all the needles in the usage status data by one.

[0043] The device control module is also used to determine that the corresponding needle is in a state of needing replacement when the number of times each needle is used is greater than or equal to a preset number of uses threshold.

[0044] In one possible implementation, the data statistics processing module is further configured to classify a preset number of needles in each cycle into insulating needles and conductive needles based on the conduction status data.

[0045] The data statistical processing module is also used to determine at least one of the needles in the insulating state among the needles in the conducting state as a set of needles to be detected.

[0046] The device control module is further configured to re-control the monitoring unit to determine the conduction status data of the needles corresponding to the set of needles to be tested, and if the conduction status data is insulation status data, determine at least one needle in the set of needles to be tested with the conduction status data being insulation status data as the target broken needle.

[0047] The needle-punching monitoring system provided in this application includes a preform mold, a needle-punching device, a monitoring unit and a control unit respectively connected to the needle-punching device. The needle-punching device is used to perform needle-punching processing on the preform mold. The needle-punching device includes a needle plate, a needle unit, and a connecting conductive wire unit connected in sequence. The monitoring unit is used to control the connecting conductive wire unit to perform periodic scanning processing on the needle unit, acquiring the conduction status data of the needle unit in each cycle. The control unit is used to acquire the conduction status data corresponding to the needle unit transmitted by the monitoring unit, changing it from insulation status data to conduction status data. This system can achieve precise control over needle breakage, needle life assessment, and needle-punching depth, improving the reliability and stability of preform preparation.

Detailed Implementation

[0062] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. For example, the first threshold and the second threshold are only used to distinguish different thresholds and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0063] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0064] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a combination of a and b, a combination of a and c, a combination of b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0065] Figure 1 This application provides a schematic flowchart of a method for preparing a preform, as illustrated in an embodiment. Figure 1 As shown, the method includes:

[0066] Step 101: Obtain the multiple resistance values ​​corresponding to the preset number of needles.

[0067] The needles referred to are the corresponding needles in the acupuncture monitoring device, and their number can be limited according to the actual application scenario. This application does not make any specific limit on this.

[0068] Specifically, each spike corresponds to a resistance value, and a preset number of spikes correspond to a preset number of resistance values.

[0069] Step 102: When at least one of the multiple resistance values ​​changes from insulation state data to conduction state data, adjust the height of the preform mold according to the preset needle penetration depth.

[0070] In this application, when the precast mold is not in contact with the needles, the resistance between the needles, measured through a wire, is infinite, indicating an insulation state. When the precast mold contacts the needles, the resistance between the needles, measured through a wire, is conductive. Therefore, when the resistance value changes from insulation to conductivity, it indicates that the corresponding needle has contacted the precast mold. If at least one resistance value changes from insulation to conductivity, meaning one needle has contacted the precast mold, the height of the precast mold is adjusted according to the preset needle penetration depth.

[0071] The preset needle penetration depth can be determined based on the highest depth in the previous preform preparation process. In this application embodiment, the preset needle penetration depth is not specifically limited and can be set according to the actual application scenario.

[0072] Step 103: Based on the adjusted height of the preform mold, control the depth of the needle insertion into the preform mold to reach the preset needle insertion depth, so as to prepare the target preform.

[0073] In this application, Figure 2 This illustration shows a scenario for preparing a target preform according to an embodiment of this application. Figure 2 As shown, the preform mold 401 includes a mold shaft, a needle plate 4021 of the needle punching device 402, and a connecting conductive wire unit 4023, which are driven by a motor and a rotating shaft. This causes the needle punching device 402 to reciprocate up and down, completing the needle punching of the preform mold 401. During the needle punching process, the preform mold 401 is driven by the motor and rotates simultaneously to completely punch the carbon fiber fabric on the surface of the entire preform mold 401. Here, the lowest point of the downward stroke of the needle unit 4022 is a fixed point, and the needle punching depth is adjusted by controlling the mold shaft up and down through a servo motor. During the preparation of the target preform, the actions of adding materials and piercing need to be repeated continuously. Due to the characteristics of carbon fiber fabric, the highest point of the mold shaft after the material is laid out changes dynamically, and its height increases irregularly. Therefore, based on the highest point of the mold shaft after the material is laid out, combined with the lowest point of the downward stroke of the piercing needle unit 4022, the height that the servo motor needs to control the mold shaft to rise can be calculated, which is to determine the preset piercing depth. Furthermore, based on the adjusted height of the preform mold, the depth to which the corresponding piercing needle penetrates the preform mold can be controlled to reach the preset piercing depth in order to prepare the target preform.

[0074] In summary, the preform preparation method provided in this application obtains multiple resistance values ​​corresponding to a preset number of needles. When at least one of the multiple resistance values ​​changes from an insulation state to a conduction state, that is, when a needle contacts the preform mold, the height of the preform mold is adjusted according to a preset needle penetration depth. Based on the adjusted preform mold height, the depth to which the corresponding needle penetrates the preform mold reaches the preset needle penetration depth, thereby preparing the target preform. This method can achieve precise control of the needle penetration depth, improving the reliability and stability of the target preform preparation.

[0075] Figure 3 This application provides a schematic flowchart of a method for preparing a preform, as illustrated in an embodiment. Figure 3 As shown, the method includes:

[0076] Step 201: Obtain the multiple resistance values ​​corresponding to the preset number of needles.

[0077] The needles referred to are the corresponding needles in the acupuncture monitoring device, and their number can be limited according to the actual application scenario. This application does not make any specific limit on this.

[0078] Specifically, each spike corresponds to a resistance value, and a preset number of spikes correspond to a preset number of resistance values.

[0079] Step 202: During the preparation of the target preform, the multiple resistance values ​​are divided into a set of resistance values ​​in the conducting state and a set of resistance values ​​in the insulating state based on a preset classification method.

[0080] In this application, during the preparation of the target preform, the resistance values ​​can be classified based on a preset classification method. The preset classification method can be to classify the resistance values ​​based on their state, classifying the resistance values ​​in the conducting state into the set of conducting state resistance values, and classifying the resistance values ​​in the insulating state into the set of insulating state resistance values.

[0081] Step 203: Determine multiple resistance values ​​in the set of conduction state resistance values ​​as usage state data.

[0082] In this application, all resistance values ​​in the set of conduction state resistance values ​​can be determined as data in use state, indicating that the corresponding multiple needles are in use state.

[0083] Step 204: For all the needles in the usage status data, the number of times they are used is accumulated by one and incremented by one from the historical usage count.

[0084] In this application, the number of times all needles in the usage status data are used can be accumulated by one from the previous historical usage count.

[0085] Step 205: If the number of times each needle is used is greater than or equal to a preset usage threshold, determine that the corresponding needle is in a state to be replaced.

[0086] In this application, when the number of times the needle is used is greater than or equal to a preset usage threshold, the needle should be replaced, and the corresponding needle is determined to be in a state to be replaced.

[0087] Step 206: Control the replacement of the needle in the state to be replaced.

[0088] In this application, the needles in the desired state can be replaced, avoiding waste and overuse of the needles, ensuring the reliability and stability of the needles, and further ensuring the reliability and stability of the preparation of the target preform.

[0089] Figure 4 This illustration shows a scenario diagram for monitoring the usage status of a lancet according to an embodiment of this application. Figure 4As shown, each number represents a needle. This embodiment uses nine needles for illustration. When not needled, the nine needles are insulated from each other. Due to the small spacing between the needles and the large size of the preform mold, at least two needles will come into contact with the carbon fiber material during needled insertion. At this time, the conductivity of the nine needles (1-9) can be detected starting with needle 1. After all needles have been detected, the resistance values ​​are divided into a conductivity resistance value set and an insulation resistance value set based on a preset classification method. The resistance values ​​in the conductivity resistance value set are determined as usage status data. The usage count of all needles corresponding to the usage status data is accumulated by one from the historical usage count. If the usage count of each needle is greater than or equal to a preset usage count threshold, the corresponding needle is determined to be in a replacement-needle state. Needles in the replacement-needle state are replaced to avoid needle waste and overuse, ensuring the reliability and stability of the needles. Furthermore, this ensures the reliability and stability of the prepared target preform.

[0090] In summary, the preform preparation method provided in this application can obtain multiple resistance values ​​corresponding to a preset number of needles. During the preparation of the target preform, the multiple resistance values ​​are divided into a set of resistance values ​​in a conducting state and a set of resistance values ​​in an insulating state based on a preset classification method. The multiple resistance values ​​in the set of resistance values ​​in the conducting state are determined as usage status data. The number of times each needle is used corresponding to the usage status data is accumulated and incremented by one based on the historical usage count. If the number of times each needle is used is greater than or equal to a preset usage count threshold, the corresponding needle is determined to be in a replacement-waiting state. The needles in the replacement-waiting state are controlled to be replaced, avoiding needle waste and overuse. The lifespan of the needles is accurately assessed, ensuring the reliability and stability of the needles. Furthermore, the reliability and stability of the prepared target preform can be guaranteed.

[0091] Figure 5 This application provides a schematic flowchart of a method for preparing a preform, as illustrated in an embodiment. Figure 5 As shown, the method includes:

[0092] Step 301: Obtain the multiple resistance values ​​corresponding to the preset number of needles.

[0093] The needles referred to are the corresponding needles in the acupuncture monitoring device, and their number can be limited according to the actual application scenario. This application does not make any specific limit on this.

[0094] Specifically, each spike corresponds to a resistance value, and a preset number of spikes correspond to a preset number of resistance values.

[0095] Step 302: During the preparation of the target preform, multiple resistance values ​​are divided into the set of resistance values ​​in the conducting state and the set of resistance values ​​in the insulating state based on a preset classification method.

[0096] In this application, during the preparation of the target preform, the resistance values ​​can be classified based on a preset classification method. The preset classification method can be to classify the resistance values ​​based on their state, classifying the resistance values ​​in the conducting state into the set of conducting state resistance values, and classifying the resistance values ​​in the insulating state into the set of insulating state resistance values.

[0097] Step 303: Determine that the needle position information is located in the set of insulation resistance values ​​between the needles corresponding to the set of conduction resistance values. The set of needles in the set of insulation resistance values ​​is the set of needles to be tested.

[0098] Figure 6 This illustration shows a scenario diagram of needle breakage detection provided by an embodiment of this application, such as... Figure 6 As shown, when the use of the lancet is detected, if lancets 1, 4, and 5 are conductive, while lancets 2 and 3 are not conductive, meaning lancets 2 and 3 are in an insulated state, then it can be determined that lancets 2 and 3 have broken. Figure 6 The diagram shows the lateral detection process; the longitudinal detection process is performed using the same procedure, which will not be elaborated here.

[0099] Step 304: Identify the target broken needle in the set of needles to be tested.

[0100] In this application, the specific implementation of step 304 above may include the following sub-steps:

[0101] Sub-step S1: Update the multiple current resistance values ​​of all needles corresponding to the set of needles to be detected.

[0102] Sub-step S2: If the current resistance value is the insulation state resistance value, determine that the needle corresponding to the current resistance value is the target broken needle.

[0103] Step 305: Control the replacement of the target broken needle.

[0104] In this application, after all needles have been tested in one cycle, the conductive needles corresponding to the resistance value of the conductive state and the insulating needles corresponding to the resistance value of the insulating state are first identified. The insulating needles are then judged again between adjacent conductive and insulating needles. If the current resistance value is the resistance value of the insulating state, the needle corresponding to the current resistance value is determined to be the target broken needle. Furthermore, the target broken needle can be replaced in a timely manner, which improves the reliability and stability of the preparation of the target preform.

[0105] In summary, the preform preparation method provided in this application can obtain multiple resistance values ​​corresponding to a preset number of needles. During the preparation of the target preform, multiple resistance values ​​are divided into a set of conducting resistance values ​​and a set of insulating resistance values ​​based on a preset classification method. Multiple needles in the set of insulating resistance values ​​whose needle position information is located between the needles in the set of conducting resistance values ​​are identified as the set of needles to be tested. Target broken needles in the set of needles to be tested are identified, and the target broken needles are controlled to be replaced. This allows for timely replacement of broken needles, improving the reliability and stability of the preparation of the target preform.

[0106] Figure 7 This application provides a schematic diagram of the structure of an acupuncture monitoring system according to an embodiment of the present application. Figure 4 As shown, the needle puncture monitoring system includes: a preform mold 401, a needle puncture device 402, a monitoring unit 403 and a control unit 404 respectively connected to the needle puncture device 402, wherein the needle puncture device 402 is used to perform needle puncture treatment on the preform mold 401.

[0107] The acupuncture device 402 includes a needle plate 4021, a needle unit 4022 and a conductive wire unit 4023 connected in sequence.

[0108] The monitoring unit 403 is used to control the connecting conductive wire unit 4023 to perform periodic scanning processing on the needle unit 4022, and to obtain the conduction status data of the needle unit 4022 in each period.

[0109] The control unit 404 is used to obtain the conduction state data corresponding to the needle unit 4022 transmitted by the monitoring unit 403 from insulation state data to conduction state data.

[0110] The scanning period corresponding to the periodic scanning can be less than or equal to 100 milliseconds or less than or equal to 110 milliseconds. This application embodiment does not make specific limitations on this, and specific settings can be made according to the actual application scenario.

[0111] In summary, the needle-punching monitoring system provided in this application includes a preform mold, a needle-punching device, a monitoring unit and a control unit respectively connected to the needle-punching device. The needle-punching device is used to perform needle-punching processing on the preform mold. The needle-punching device includes a needle plate, a needle unit, and a connecting conductive wire unit connected in sequence. The monitoring unit is used to control the connecting conductive wire unit to perform periodic scanning processing on the needle unit, acquiring the conduction status data of the needle unit in each cycle. The control unit is used to acquire the conduction status data corresponding to the needle unit transmitted by the monitoring unit, changing it from insulation status data to conduction status data. This system can achieve precise control over needle breakage, needle life assessment, and needle-punching depth, improving the reliability and stability of preform preparation.

[0112] Optional, see Figure 4 The needle unit 4022 includes a preset number of needles A spaced apart. The connecting conductive wire unit 4023 includes a number of connecting conductive wires E that are the same as the number of needles A corresponding to the needle unit 4022. One end of the preset number of connecting conductive wires E is connected to the corresponding needle A one by one, and the other end is connected to the monitoring unit 403. The monitoring unit 403 is connected to the control unit 404.

[0113] The contact portions of the predetermined number of needles A in the needle unit 4022 and the needle plate 4021 are insulated contacts.

[0114] This application does not impose specific restrictions on the number of needles or the corresponding number of conductive wires; these can be adjusted according to the actual application scenario.

[0115] Optionally, the control unit includes a data statistics processing module and a device control module connected in sequence; wherein the data statistics processing module is connected to the monitoring unit; wherein the monitoring unit only determines the conduction state and the insulation state, and does not measure the specific resistance value.

[0116] The device control module is used to control the monitoring unit to perform periodic scanning processing on the needle unit through the connecting conductive wire unit;

[0117] The data statistics processing module is used to obtain the conduction status data of each needle corresponding to each connecting conductive line in each cycle transmitted by the monitoring unit.

[0118] The device control module is also used to adjust the height of the preform mold according to a preset needle penetration depth when the conduction state data corresponding to at least one of the needles transmitted by the monitoring unit changes from insulation state data to conduction state data. This controls the depth to which the needle penetrates the preform mold to reach the preset needle penetration depth, thereby preparing the target preform. This allows for precise control of the needle penetration depth, improving the reliability and stability of the target preform preparation.

[0119] Optionally, the data statistics processing module is further configured to determine all needles in the conduction state as being in use state data;

[0120] The device control module is also used to accumulate and increment the historical usage count of all the needles in the usage status data by one.

[0121] The device control module is also used to determine that the corresponding needle is in a state of needing replacement when the number of times each needle is used is greater than or equal to a preset number of uses threshold.

[0122] In this application, the device control module can replace the needles in the state to be replaced, avoiding waste and overuse of the needles, ensuring the reliability and stability of the needles, and further ensuring the reliability and stability of the preparation of the target preform.

[0123] Optionally, the data statistics processing module is further configured to classify a preset number of needles in each cycle into insulating needles and conductive needles based on the conduction status data.

[0124] The data statistical processing module is also used to determine at least one of the needles in the insulating state among the needles in the conducting state as a set of needles to be detected.

[0125] The device control module is also used to re-control the monitoring unit to determine the conduction status data of the needles corresponding to the set of needles to be tested. If the conduction status data is insulation status data, at least one needle in the set of needles to be tested with insulation status data is identified as a target broken needle. The module then controls the replacement of the target broken needle, which allows for timely replacement of broken needles and improves the reliability and stability of the preparation of the target preform.
