Description

Technical Field

[0001] This invention relates to the field of battery pack testing technology, and in particular to a probe range-changing method, system, device and medium based on a laser sensor. Background Technology

[0002] With the rapid development of new energy vehicles, the performance testing of battery packs, which serve as the power source for these vehicles, is becoming increasingly important, and battery pack products are becoming more and more diversified. Because the positions of the terminals (positive and negative electrode spacing) are inconsistent for each battery pack model, the production line needs to adjust the probe spacing—that is, change the probe type—to be compatible with the testing of multiple battery pack models.

[0003] Traditionally, probe changing involves manually moving the probe block to install the probes, requiring manual intervention for each change, resulting in low efficiency and consequently affecting battery pack testing efficiency. Therefore, providing a probe spacing method, system, device, and medium based on a laser sensor to improve probe changing efficiency has become a pressing technical problem. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a probe range-changing method, system, device and medium based on a laser sensor to improve probe changeover efficiency.

[0005] In a first aspect, the present invention provides a probe ranging method based on a laser sensor, comprising the following steps:

[0006] Step S1: After the servo screw of the probe module controlled by the PLC is reset, the laser sensor is moved by the servo motor to position each probe block on the probe module with probes installed, and the positioning data of each probe block is recorded in real time.

[0007] Step S2: The PLC calculates the initial spacing of each probe based on the positioning data;

[0008] Step S3: Based on the received change command, the PLC drives the pressure cylinder to press the unlocking block of each probe block to unlock each probe block.

[0009] Step S4: Based on the type change command and the initial spacing, the PLC controls the servo screw to rotate in order to automatically adjust the spacing of each probe.

[0010] Furthermore, step S2 specifically includes:

[0011] Based on the positioning data and the installation position of the probes on the probe block, the PLC automatically calculates the initial spacing and initial position of each probe, and writes the initial spacing and initial position into the RFID chip installed in the probe block.

[0012] Furthermore, step S3 specifically includes:

[0013] Based on the received change command carrying the target spacing, the PLC drives the pressure cylinder to press the unlocking block of each probe block to unlock each probe block.

[0014] Furthermore, step S4 specifically includes:

[0015] The PLC calculates the moving distance based on the target spacing and initial spacing carried by the changeover command. Based on the moving distance, it controls the servo screw to rotate clockwise or counterclockwise to automatically adjust the spacing of each probe. The actual spacing of each probe is measured by a laser sensor. The PLC drives the pressing cylinder to reset, so that the unlocking block is reset under the elastic force of the spring to lock the current position. It determines whether the error between the actual spacing and the target spacing is greater than the set error threshold. If not, the probe changeover is completed; if so, an alarm is triggered for excessive error.

[0016] Secondly, the present invention provides a probe ranging system based on a laser sensor, comprising the following modules:

[0017] The probe block positioning module is used to position each probe block on the probe module with probes installed by the laser sensor through the servo motor after the servo screw of the probe module is reset by the PLC control. The positioning data of each probe block is recorded in real time.

[0018] The initial spacing calculation module is used by the PLC to calculate the initial spacing of each probe based on the positioning data;

[0019] The probe block unlocking module is used by the PLC to drive the pressure cylinder to press the unlocking block of each probe block based on the received change command, so as to unlock each probe block.

[0020] The probe switching module is used by the PLC to control the servo screw to rotate based on the probe switching command and the initial spacing, so as to automatically adjust the spacing of each probe.

[0021] Furthermore, the initial spacing calculation module is specifically used for:

[0022] Based on the positioning data and the installation position of the probes on the probe block, the PLC automatically calculates the initial spacing and initial position of each probe, and writes the initial spacing and initial position into the RFID chip installed in the probe block.

[0023] Furthermore, the probe block unlocking module is specifically used for:

[0024] Based on the received change command carrying the target spacing, the PLC drives the pressure cylinder to press the unlocking block of each probe block to unlock each probe block.

[0025] Furthermore, the type-changing module is specifically used for:

[0026] The PLC calculates the moving distance based on the target spacing and initial spacing carried by the changeover command. Based on the moving distance, it controls the servo screw to rotate clockwise or counterclockwise to automatically adjust the spacing of each probe. The actual spacing of each probe is measured by a laser sensor. The PLC drives the pressing cylinder to reset, so that the unlocking block is reset under the elastic force of the spring to lock the current position. It determines whether the error between the actual spacing and the target spacing is greater than the set error threshold. If not, the probe changeover is completed; if so, an alarm is triggered for excessive error.

[0027] Thirdly, the present invention provides a probe range-changing device based on a laser sensor, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method described in the first aspect.

[0028] Fourthly, the present invention provides a probe-varying medium based on a laser sensor, on which a computer program is stored, which, when executed by a processor, implements the method described in the first aspect.

[0029] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0030] After the servo screw of the probe module is reset by the PLC, the laser sensor is moved by the servo motor to position each probe block on the probe module with probes installed. The positioning data of each probe block is recorded in real time, and the initial spacing of each probe is calculated based on the positioning data. Then, the PLC drives the cylinder to press the unlocking block of each probe block based on the change command to unlock each probe block. The moving distance is calculated based on the change command and the initial spacing, and the servo screw is controlled to rotate based on the moving distance to automatically adjust the spacing of each probe. In other words, the PLC positions the probes through the laser sensor and drives the servo screw to automatically move the probes to change the spacing, without manual operation, which greatly improves the probe change efficiency and the battery pack testing efficiency.

[0056] The probe switching module is used by the PLC to control the servo screw to rotate based on the probe switching command and the initial spacing, so as to automatically adjust the spacing of each probe.

[0057] The initial spacing calculation module is specifically used for:

[0058] Based on the positioning data and the installation position of the probes on the probe block, the PLC automatically calculates the initial spacing and initial position of each probe, and writes the initial spacing and initial position into the RFID chip installed in the probe block.
