Description

Technical Field

[0001] The present invention relates to the field of distribution boxes, and in particular to a distribution box detection method and a distribution box unit with highly integrated high and low voltage circuits. Background Art

[0002] A distribution box is a device that centrally installs switches, electrical components, wiring terminals, etc., and is used to distribute, control, and protect circuits.

[0003] Currently, the housing of a distribution box is typically produced through injection molding, which offers advantages in molding precision and mass production. Injection molding allows for the simultaneous molding of complex structures. Through precise mold design, various functional features, such as clips, slots, and heat dissipation holes, can be integrated into the housing to meet the assembly and operational requirements of the distribution box.

[0004] Most existing automated testing equipment can only test one or several parameters of the distribution box, and cannot effectively test the snap fasteners in the mechanical structure, which in turn reduces the subsequent assembly efficiency of the distribution box and needs to be improved. Summary of the Invention

[0005] In order to improve the subsequent assembly efficiency of a distribution box, the present invention provides a distribution box detection method and a distribution box unit with highly integrated high and low voltage circuits.

[0013] By adopting the above technical solution, upon receiving the detection signal, the cover plate image information is quickly collected, and then the opening characteristics of the snap position are identified and judged. If the opening characteristics are present, the opening size is further identified and compared with the reference opening size. If there is any inconsistency, an abnormality is reported. If the snap position does not have an opening feature or an abnormal opening is indicated, the snap opening wire is controlled to perform the opening operation according to a preset method.

[0053] In a second aspect, the present application provides a distribution box unit with highly integrated high and low voltage circuits, which is applied to a distribution box detection method according to the first aspect for detection, and adopts the following technical solution:

[0054] A power distribution box unit with highly integrated high and low voltage circuits, comprising a cover plate, a base snap-fitted with the cover plate, and internal components, wherein the cover plate and the base snap-fitted together to form an accommodating cavity, and the internal components are installed in the accommodating cavity;

[0055] The internal components include an integrated board and electrical components inserted and installed on the integrated board. The integrated board is provided with a high-voltage acquisition copper bus and a low-voltage control copper bus to achieve high integration of the high-voltage acquisition circuit and the low-voltage control circuit.

[0056] Optionally, the electrical component is provided with an insertion pin for inserting the electrical component into the integrated board, and the insertion pin passes through the high-voltage collection copper bus and the low-voltage control copper bus and is inserted into the integrated board.

[0057] Optionally, the electrical component includes a pre-charging relay, a relay, and a pre-charging resistor, the pre-charging resistor and the relay each have two insertion pins, and the pre-charging relay has four insertion pins;

[0059] In summary, this application includes at least one of the following beneficial technical effects:

[0060] 1. After receiving the detection signal, the image information of the cover is quickly collected, and then the opening features of the buckle position are identified and judged. If the opening features exist, the opening size is further identified and compared with the reference opening size. If there is any inconsistency, an abnormal prompt is reported. Once the opening features do not exist at the buckle position or there is an opening abnormality prompt, the buckle opening wire is controlled to perform the opening operation according to the preset method. In this way, the buckle opening problem can be discovered and solved in time, ensuring that the distribution box buckle opening meets the assembly requirements, reducing assembly obstacles caused by opening problems, and improving the subsequent distribution box assembly efficiency;

[0061] 2. By first understanding the required temperature value and then combining it with the current intensity value to determine the power-on duration, scientific parameters are provided for heating the thin wires for the buckle opening. The buckle opening device is controlled to heat the thin wires according to the parameters. After heating, the operation is flexibly adjusted by identifying the blockage of the buckle. If the buckle is completely blocked, a thin wire is inserted for secondary heating and the opening is made along the preset route. This ensures that the buckle blockage problem is accurately removed without damaging the cover. This effectively responds to the buckle opening requirements in different situations and avoids the quality of the distribution box being affected by improper opening.

[0062] 3. The integrated board in the internal components integrates the high-voltage collection circuit and the low-voltage control circuit by setting the high-voltage collection copper busbar and the low-voltage control copper busbar, effectively reducing the number of components such as wiring harnesses, connectors, and connection terminals, thereby controlling costs, reducing the risk of interference between circuits, improving the integration and space utilization of the distribution box, and making the installation and connection of electrical components more compact and orderly, thereby improving the working stability and reliability of the distribution box.

[0072] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0073] Reference Figure 1 The present invention discloses a highly integrated power distribution box unit with high and low voltage circuits, comprising a cover 1, a base 2, and internal components 3. The cover 1 is provided with six clips 11, and the base 2 is provided with slots 21 equal in number to the clips 11. The clips 11 on the cover 1 are engaged with the slots 21 on the base 2 to form a power distribution box, which has an internal receiving chamber 4, into which the internal components 3 are mounted.

[0074] Reference Figure 1 and Figure 2 The internal components 3 include an integrated board 31, electrical components 32 and fuses 33. A high-voltage collection copper bus 311 and a low-voltage control copper bus 312 are provided on the integrated board 31, so that a high-voltage collection circuit and a low-voltage control circuit can be formed on the integrated board 31 at the same time, thereby forming a highly integrated high and low voltage circuit.

[0075] Reference Figure 1 and Figure 3 The electrical component 32 is inserted and mounted on the integrated board 31, and an insertion pin 324 is provided on the electrical component 32. The insertion pin 324 passes through the high-voltage collection copper bus 311 and the low-voltage control copper bus 312 and is inserted into the integrated board 31. An insulating film 34 is also provided between the electrical component 32 and the integrated board 31 to effectively isolate the current generated by the electrical component 32 during operation.

[0076] The electrical component 32 includes a pre-charging relay 321, a relay 322, and a pre-charging resistor 323. The pre-charging resistor 323 and the relay 322 each have two insertion pins 324, and the pre-charging relay 321 has four insertion pins 324. The two insertion pins 324 of the pre-charging resistor 323 and two of the insertion pins 324 of the pre-charging relay 321 pass through the high-voltage collection copper bus 311 and are inserted into the integrated board 31. The two insertion pins 324 of the relay 322 and the other two insertion pins 324 of the pre-charging relay 321 pass through the low-voltage control copper bus 312 and are inserted into the integrated board 31.

[0077] Reference Figure 1 and Figure 3 The high-voltage collection copper bus 311 includes a connecting copper bus 3111 and a sampling copper bus 3112. The sampling copper bus 3112 and the low-voltage control copper bus 312 are arranged on the integrated board 31. The connecting copper bus 3111 is connected to the pre-charge relay 321, the relay 322 and the fuse 33 in sequence, and the connecting copper bus 3111 is fixed to the pre-charge relay 321, the relay 322 and the fuse 33 by bolts, and is fixed to the sampling copper bus 3112 by bolts.

[0078] Reference Figure 1 and Figure 4 Based on the same inventive concept, an embodiment of the present invention provides a method for detecting a distribution box, comprising the following steps:

[0079] S1: Responding to a preset detection signal to collect cover image information.

[0080] The detection signal refers to a signal indicating that the cover plate 1 needs to be inspected. The detection signal is pre-set by a person skilled in the art and will not be described in detail here. The cover plate image information refers to an image of the appearance of the cover plate 1. The cover plate image information is obtained by taking a picture with a camera.

[0081] S2: Recognizing a preset opening feature at a preset buckle position from the cover image information to determine whether the buckle position has an opening feature.

[0082] The snap position refers to the position of the snap 11 on the cover 1. The opening feature refers to the appearance and contour features of the opening presented at the snap position on the cover 1. The snap position and opening feature are both pre-set by those skilled in the art and will not be described in detail here. The cover image information can be used to identify whether the opening feature exists at the snap position, thereby determining whether the snap 11 on the cover 1 is opened. The cover image information can identify whether the opening feature exists at the snap position, which is an image recognition technology. Image recognition technology is common knowledge in the field and will not be described in detail here.

[0083] S3: When there is an opening feature at the buckle position, the opening feature is identified from the cover plate image information to obtain the buckle opening size.

[0084] The buckle opening size refers to the specific size of the opening represented by the opening feature at the buckle position on the cover plate 1. The size of the opening feature in the cover plate image information can be determined by scanning and identifying the opening feature. The actual buckle opening size can then be determined by understanding the preset image ratio of the cover plate image information. The preset image ratio of the cover plate image information is pre-set by those skilled in the art and will not be detailed here.

[0085] When there is an opening feature at the buckle position, it means that the buckle 11 on the cover 1 has been opened, and the size of the buckle opening needs to be identified first for subsequent steps.

[0086] S30: When the buckle opening size is inconsistent with the preset reference opening size, an opening abnormality prompt is reported.

[0087] The reference opening size refers to the size that the opening feature of the buckle 11 should reach. The reference opening size is set in advance by those skilled in the art and will not be described in detail here.

[0088] When the buckle opening size is inconsistent with the reference opening size, it means that the buckle 11 has not completed the opening operation completely, and an opening abnormality prompt needs to be reported for subsequent steps.

[0089] S300: When there is no opening feature at the buckle position or an opening abnormality prompt is reported, the preset buckle opening line is controlled to open the buckle 11 using a preset opening method.

[0090] The buckle opening line refers to a line used to completely open the buckle 11. In this embodiment, the buckle opening line is made of a rigid material. The opening method refers to the method used to completely open the buckle 11. The specific opening method is described in detail in subsequent steps S301 to S30413 and is not further described here.

[0091] If there is no opening feature at the buckle position, it means that the buckle 11 on the cover 1 is not opened, and the buckle opening line needs to be controlled to open the buckle 11. At the same time, if an opening abnormality notification is received, the buckle opening line needs to be controlled to open the buckle 11.

[0092] Reference Figure 5 and Figure 6 , the opening method comprises the following steps:

[0093] S301: Collect cover material information.

[0094] The cover plate material information refers to the material used in the production of the cover plate 1. The cover plate material information is pre-input by the staff and then retrieved.

[0095] S302: Generate a required temperature value based on the cover material information.

[0096] The required temperature value refers to the temperature that the clip opening line must reach. The required temperature value corresponding to the cover material information can be found using a preset temperature comparison table. This table records the different required temperature values ​​corresponding to different cover materials. The temperature comparison table is generated by those skilled in the art through sequential testing of the different required temperature values ​​corresponding to different cover materials, and will not be detailed here.

[0097] S303: Generate a power-on duration based on the required temperature value and the preset current intensity value.

[0098] The current intensity value refers to the current intensity when the buckle opening device electrically heats the buckle opening wire. The current intensity value is pre-determined by those skilled in the art and is not detailed here. The buckle opening device is a device used to electrically heat the buckle opening wire and drive the buckle opening wire to move.

[0099] The power-on duration refers to the duration during which the buckle opening device electrically heats the buckle opening wire. The power-on duration corresponding to the required temperature value and current intensity value can be queried using a preset power-on comparison table. This comparison table records the different power-on durations corresponding to different required temperature values ​​and current intensity values. This table is created by those skilled in the art through sequential testing and recording of different power-on durations corresponding to different required temperature values ​​and current intensity values, and will not be described in detail here. Furthermore, when the current intensity value is fixed, the higher the required temperature value, the longer the power-on duration.

[0100] S304: Control the preset buckle opening device to energize and heat the buckle opening wire with a current intensity value. After the power-on time, control the buckle opening device to stop energizing, and identify the preset buckle features from the cover image information to obtain the buckle blockage situation.

[0101] Buckle features refer to the baseline appearance and contour features of buckle 11. Buckle features are pre-defined by those skilled in the art and will not be described in detail here. Buckle blockage refers to the degree and state of blockage of the opening on buckle 11. By performing contour recognition of the buckle features from the cover image information, the outer contour of buckle 11 can be determined, and thus the buckle blockage status can be determined. When buckle 11 is blocked, its contour changes, resulting in deformation, irregularity, and the like. By analyzing these contour changes, the blockage status can be determined.

[0102] The buckle opening device is controlled to energize and heat the buckle opening wire with a current intensity value. After the power-on time, the buckle opening device is controlled to stop energizing and identify the buckle blockage situation for subsequent steps.

[0103] S3040: When the buckle is completely blocked, the buckle opening wire is controlled to be inserted into the preset buckle opening position. After the insertion is completed, the buckle opening device is controlled to energize and heat the buckle opening wire again with the current intensity value, and the buckle opening wire is controlled to open the buckle 11 along the preset opening route.

[0104] The buckle opening position refers to the initial position of the buckle opening wire when the buckle is completely blocked. The opening path refers to the path of the buckle opening wire after it is inserted into the buckle opening position to open the buckle when the buckle is completely blocked. The buckle opening position and the buckle opening wire are both pre-determined by those skilled in the art and are not described in detail here.

[0105] When the buckle is completely blocked, that is, there is no opening feature at the buckle position mentioned in S300 above, it is necessary to control the buckle opening device to insert the buckle opening wire into the buckle opening position. After the insertion is completed, the buckle opening device is controlled to energize and heat the buckle opening wire again with the current intensity value, and control the buckle opening wire to open the buckle 11 along the opening route.

[0106] Reference Figure 7 and Figure 8 , the opening method further comprises the following steps:

[0107] S3041: When the buckle blockage condition is incomplete blockage, a contour scan is performed on a preset blocking feature from the cover plate image information to obtain a buckle blockage contour.

[0108] The buckle blockage profile refers to the outline of the material blocking the buckle 11 when the buckle 11 is partially blocked, as seen in the cover image information. The buckle blockage profile is obtained by performing a contour scan of the blocking material features from the cover image information. The blocking material features refer to the characteristics of the material blocking the buckle 11 within the cover image information that can be used to identify and distinguish the material. The blocking material features are pre-determined by those skilled in the art and are not detailed here.

[0109] When the buckle is not completely blocked, it means that there is an opening feature at the buckle position. The buckle blockage outline needs to be identified first for subsequent steps.

[0110] S30410: Generate the blocking edge position based on the snap blocking contour and snap features.

[0111] The obstruction edge location refers to the intersection of the edge of the material blocking buckle 11 and the buckle's own structure when buckle 11 is partially blocked. Understanding the buckle's obstruction profile allows us to determine the shape and range of the obstructing material. Combined with buckle 11's own characteristics, such as its shape, size, and structure, we can determine the intersection or proximity of the obstructing material with the buckle's structure, and thus determine the boundary of the obstructing material on buckle 11—that is, the obstruction edge location.

[0112] S30411: Generate thin-line cutting routes based on blocking edge positions, buckle blocking contours, and buckle features.

[0113] The fine-wire cutting path is the planned movement path for the buckle opening fine wire to cut the buckle 11 when the buckle 11 is partially blocked. By first understanding the blockage edge position, we can clearly define the boundary where the blocking material intersects with the buckle 11 structure. The buckle blockage profile is then used to determine the shape and distribution of the blocking material. Furthermore, considering the shape, size, and structure of the buckle 11 itself, we can determine a fine-wire cutting path that allows the buckle opening fine wire to effectively clear the blocking material.

[0114] S30412: Obtain the initial position of the thin line based on the blocked edge position.

[0115] The initial position of the thin line refers to the starting position where the clip opening thin line begins to enter the clip 11 for cutting. By understanding the blocking edge position, a specific point where the blocking material edge intersects the structure of the clip 11 can be known, and this specific point is used as the initial position of the thin line.

[0116] S30413: Control the buckle opening wire to be inserted into the initial position of the wire. After the insertion is completed, control the buckle opening device to energize and heat the buckle opening wire again with the current intensity value, and control the buckle opening wire to open the buckle 11 along the wire cutting route.

[0117] The buckle opening device is controlled to insert the buckle opening wire into the initial position of the wire. After the insertion is completed, the buckle opening device is controlled to energize and heat the buckle opening wire again with the current intensity value, and the buckle opening wire is controlled to open the buckle 11 along the wire cutting route, thereby completing the opening of the buckle 11.

[0118] The insertion detection method includes the following steps:

[0119] S31: When the buckle opening size is consistent with the preset reference opening size, the preset insertion device is controlled to insert the preset electrical component 32 into the preset integrated board 31, and the insertion image information is collected.

[0120] The insertion device is a device used to insert the electrical component 32 into the integrated board 31. The electrical component 32 refers to all electronic components within the distribution box. The integrated board 31 is the object used to integrate all electronic components within the distribution box. The insertion image information refers to an image of the electrical component 32 inserted into the integrated board 31. The insertion image information is captured by a camera.

[0121] When the buckle opening size is consistent with the reference opening size, it means that the buckle 11 has been completely opened. It is necessary to control the insertion device to insert the electrical component 32 into the integrated board 31 and collect the insertion image information for subsequent steps.

[0122] S310: Performing posture recognition on the electrical component 32 from the insertion image information to obtain the component insertion posture.

[0123] The component insertion posture refers to the spatial position and orientation of the electrical component 32 relative to the integrated board 31 when the electrical component 32 is inserted into the integrated board 31. The component insertion posture can be determined by performing posture recognition on the electrical component 32 from the insertion image information. Image posture recognition technology is well known in the art and will not be elaborated on here.

[0124] S3100: When the component insertion posture is consistent with the preset reference insertion posture, control the preset pressing device to press down the electrical component 32 with a preset pressing force value.

[0125] The reference insertion posture refers to the posture that the electrical component 32 should assume when inserted into the integrated board 31. The downward pressure device refers to the device used to further insert the electrical component 32 into the integrated board 31. The downward pressure value refers to the force applied when further inserting the electrical component 32 into the integrated board 31. The reference insertion posture and downward pressure value are both pre-determined by those skilled in the art and are not detailed here.

[0126] When the component insertion posture is consistent with the reference insertion posture, it indicates that the electrical component 32 has been correctly inserted into the integrated board 31 , and the pressing device can be directly controlled to press the electrical component 32 downward with a downward pressure value.

[0127] S3101: When the component insertion posture is inconsistent with the preset reference insertion posture, the specific electrical component whose component insertion posture is inconsistent with the reference insertion posture is marked from the insertion image information.

[0128] The specific electrical component refers to the electrical component whose insertion posture is inconsistent with the reference insertion posture on the integrated board 31. The electrical component 32 whose insertion posture is inconsistent with the reference insertion posture can be identified from the insertion image information and then marked to obtain the specific electrical component.

[0129] When the component insertion posture is inconsistent with the reference insertion posture, it means that the electrical component 32 is not correctly inserted into the integrated board 31, and the specific electrical component needs to be marked first for subsequent steps.

[0130] S31010: Control the preset posture adjustment device to re-plug the specific electrical component, and after re-plugging, control the preset pressing device to press down the electrical component 32 with a preset pressing force value.

[0131] The posture adjustment device is a device used to re-insert or remove the electrical component 32 that is not correctly inserted into the integrated board 31 .

[0132] After a specific electrical component is identified, the posture adjustment device needs to be controlled to re-plug the specific electrical component, and after re-plugging, the pressing device is controlled to press the electrical component 32 downward with a downward pressure value.

By comparing the current cover color with the base cover color, the location of the color difference can be identified and marked to determine the abnormal color location.

[0171] When the current color of the cover is different from the reference color of the cover, it means that the cover 1 is lifted up by the electrical component 32 inside the distribution box, resulting in color abnormality, which further indicates that the installation of the electrical component 32 inside the distribution box is abnormal. The abnormal color position needs to be compared for subsequent steps.

[0172] S315: Collecting the model information of the power distribution box.

[0173] PDB model information refers to a combination of specific parameters and features used to identify and distinguish different types of PDBs. PDB model information is pre-entered by staff and then retrieved.
