[0004] The purpose of this invention is to provide a special inspection tool for the output pole of a battery pack, which reduces the difficulty of detecting the size and features of the output pole with a special shape and improves the detection efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A dedicated inspection fixture for battery pack output terminals includes an output terminal with a stepped portion in the middle, the surface of which is coated with an insulating coating. One end of the output terminal has a first conductive portion, and the other end has a second conductive portion. Both the first and second conductive portions have several mounting and positioning holes. The first conductive portion has a raised bulge, and the second conductive portion is tilted upwards at a predetermined angle relative to the first conductive portion. The fixture also includes a base with a stepped surface adapted to the shape of the output terminal. A recess for placing the output terminal is provided on the stepped surface. To check whether the external dimensions of the output electrode meet the standards, several detection pins are set in the sink, each detection pin corresponding to a mounting positioning hole. The detection pins are used to check whether the hole position and diameter of the mounting positioning hole meet the standards. Several clamping positions and detection positions are set on the outer ring of the sink. The clamping positions are equipped with clamping parts for pressing the first conductive part into the sink. Each detection position is equipped with a detection element for checking whether the position and thickness of the insulating coating meet the standards, whether the height and thickness of the bulge meet the standards, or whether the thickness, tilting height and angle of the second conductive part meet the standards.

[0007] As an optional solution, there are two clamping positions, which are distributed on both sides of the first conductive part. The clamping device is a quick clamp, which is used to quickly clamp or release the first conductive part.

[0008] As an optional solution, the testing component includes a fixing block fixed on the base, with the testing block passing through the fixing block. The testing block can approach or move away from the output electrode, and a size-limiting slot is provided at the end of the testing block facing the output electrode. The size-limiting slot is used to insert the testing block into the corresponding part of the output electrode when it approaches the output electrode, and the corresponding part of the qualified output electrode can be accurately inserted into the size-limiting slot.

[0009] As an alternative, the upper surface of the detection block is attached to the fixed block, the lower surface of the detection block is provided with a protrusion, and the base is provided with a guide groove that mates with the protrusion.

[0010] As an alternative, the detection position includes a first detection position located on one or both sides of the insulating coating. The size of the detection block in the first detection position defines the slot to be inserted into the insulating coating to detect the position and thickness of the insulating coating.

[0011] As an alternative, the detection position includes a second detection position located on one side of the first conductive part. The size of the detection block in the second detection position defines the slot to be inserted into the convex hull to detect the position and thickness of the convex hull.

[0012] As an alternative, the detection position includes a third detection position located on one side of the second conductive part. The size of the detection block in the third detection position defines the slot to be inserted into the second conductive part to detect the position and thickness of the second conductive part.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0026] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Figure 1 The output electrode 1 shown has a stepped portion in the middle, and the surface of the stepped portion is coated with an insulating coating 11. One end of the output electrode 1 has a first conductive portion 12, and the other end has a second conductive portion 13. Both the first conductive portion 12 and the second conductive portion 13 have several mounting and positioning holes 14. The first conductive portion 12 has a protrusion 15, and the second conductive portion 13 is raised at a predetermined angle relative to the first conductive portion 12. Therefore, this utility model provides a special inspection tool for battery pack output electrodes to check whether the various features and dimensions of this type of output electrode 1 meet the standards.

[0029] like Figure 2 and Figure 3 As shown, the dedicated inspection tool for the output pole of the battery pack includes a base 2. The base 2 has a stepped surface adapted to the shape of the output pole 1. A recessed groove 21 for placing the output pole 1 is provided on the stepped surface. The recessed groove 21 is used to check whether the external dimensions of the output pole 1 meet the standards. Several inspection pins 22 are provided in the recessed groove 21. Each inspection pin 22 corresponds to each mounting positioning hole 14. The inspection pins 22 are used to check whether the hole position and hole diameter of the mounting positioning hole 14 meet the standards. Several clamping positions 23 and inspection positions are provided on the outer ring of the recessed groove 21. Clamping positions 23 are provided with clamping parts for pressing the first conductive part 12 into the recessed groove 21. Inspection pieces are provided in each inspection position. The inspection pieces are used to check whether the position and thickness of the insulating coating 11 meet the standards, whether the height and thickness of the protrusion 15 meet the standards, or whether the thickness, tilting height and angle of the second conductive part 13 meet the standards.

[0030] Therefore, for the output pole 1 with special shape and characteristics, a sink 21, a detection pin 22, a clamping component and a detection component are designed. The full-size and full-feature detection can be completed in one clamping, which greatly reduces the difficulty and complexity of detection, improves the detection efficiency, and meets the needs of batch rapid inspection.

[0031] When the output electrode 1 is placed in the sink 21, the external dimensions can be quickly determined based on the gap between the outer contour of the output electrode 1 and the side wall of the sink 21. Specifically, the gap between the two sides of the standard output electrode 1 and the sink 21 is designed to be 0.15mm, so the width of the output electrode product can be detected to be ±0.3mm. The gap between the first conductive part 12 of the standard output electrode 1 and the sink 21 is designed to be 0.15mm, and the gap between the second conductive part 13 and the sink 21 is designed to be 0.35mm, so the length of the output electrode product can be detected to be ±0.3mm.

[0032] Similarly, after the output electrode 1 is placed in the sink 21, the position and diameter of the mounting positioning holes 14 on the output electrode 1 can be quickly determined according to the fit between the corresponding detection pins 22 and the mounting positioning holes 14.

[0033] Before performing various feature and size inspections, the output electrode 1 needs to be clamped and fixed. In this embodiment, there are two clamping positions 23, which are distributed on both sides of the first conductive part 12. The clamping device is a quick clamp, which is used to quickly clamp or release the first conductive part 12.

[0034] By using two quick clamps distributed on both sides, the first conductive part 12 of the output electrode 1 is quickly clamped, ensuring the stable position of the output electrode 1 and avoiding deformation due to pressure on one side, resulting in more balanced force and thus ensuring the accuracy of subsequent testing.

[0035] Optionally, the detection component includes a fixing block 3 fixed on the base 2, a detection block 4 passing through the fixing block 3, the detection block 4 being able to approach or move away from the output pole 1, and a size limiting slot 41 being provided at the end of the detection block 4 facing the output pole 1, the size limiting slot 41 being used to insert the detection block 4 into the corresponding part of the output pole 1 when it approaches the output pole 1, and the corresponding part of the qualified output pole 1 being able to be accurately inserted into the size limiting slot 41.

[0036] By defining the slot size using standard specifications (41), the testing standard is quantified, transforming subjective judgment into an objective "pass / fail" test. This facilitates quick manual judgment when testing the location and size, resulting in high testing efficiency.

[0037] Furthermore, the upper surface of the detection block 4 is in contact with the fixed block 3, and the lower surface of the detection block 4 is provided with a protrusion 42. The base 2 is provided with a guide groove 27 that cooperates with the protrusion 42, thereby ensuring the precise movement of the detection block 4.

[0038] In this embodiment, the detection position includes a first detection position 24, which is located on one or both sides of the insulating coating 11. The size of the detection block 4 in the first detection position 24 is defined by the slot 41 inserted into the insulating coating 11 to detect the position and thickness of the insulating coating 11.

[0039] Since the insulating coating 11 directly affects the insulation performance of the output electrode 1, it is necessary to inspect its coating quality to promptly detect problems such as missed coating, excessive thinness, or misalignment of the insulating coating 11, and to prevent defects. Specifically, the size of the detection block 4 in the first detection position 24 is designed to limit the width of the slot 41 to 3.6mm. When it is inserted into the corner area of ​​the insulating coating 11, the thickness of the insulating coating 11 can be detected as 3.4mm ± 0.2mm. The size of the detection block 4 in the first detection position 24 is designed to limit the width of the slot 41 to 3.0mm. When it is inserted into the edge area of ​​the insulating coating 11, the contour position of the insulating coating 11 can be detected as ± 1.5mm.

[0040] In this embodiment, the detection position includes a second detection position 25, which is located on one side of the first conductive part 12. The size of the detection block 4 in the second detection position 25 is defined by the slot 41 inserted into the protrusion 15 to detect the position and thickness of the protrusion 15.

[0041] Specifically, the size of the detection block 4 in the second detection position 25 is limited to the groove width of the slot 41, which is designed to be 1.6mm. When it is inserted into the convex 15, the thickness of the convex 15 (1.3mm ± 0.2mm) and the height of the convex 15 can be detected.

[0042] In this embodiment, the detection position includes a third detection position 26, which is located on one side of the second conductive part 13. The size-limiting slot 41 of the detection block 4 in the third detection position 26 is inserted into the second conductive part 13 to detect the position and thickness of the second conductive part 13.

[0043] Specifically, the size of the detection block 4 in the third detection position 26 is limited to the slot width of the slot 41, which is designed to be 1.8mm. When it is inserted into the second conductive part 13, the thickness of the second conductive part 13 (16.5mm ± 0.3mm) and the angle of 0.35° with the first conductive part 12 can be detected.

[0044] Furthermore, two third detection positions 26 are provided, and the two third detection positions 26 are distributed on both sides of the second conductive part 13 to check whether the degree of curvature of the two sides of the second conductive part 13 is consistent.

[0045] In use, 1) place the output electrode 1 in the recess 21, aligning each mounting positioning hole 14 of the output electrode 1 with the detection pin 22. If the position and diameter of each mounting positioning hole 14 are accurate, proceed to the next step; 2) use quick clamps to fix the first conductive part 12 on the base 2; 3) push each detection block 4 to the corresponding part of the output electrode 1. By limiting the fit between the slot 41 and the corresponding part, the standard can be visually reflected.

[0046] Therefore, this dedicated inspection tool for battery pack output poles enables efficient and accurate inspection of specially shaped output pole products. It quickly determines the external dimensions by utilizing the gap between the output pole 1 and the recess 21, inspects the hole position and diameter by using the cooperation between the inspection pin 22 and the mounting positioning hole 14, and transforms subjective measurement of various features and dimensions into intuitive judgment by using the size-limited slot 41, which significantly improves inspection efficiency and consistency, and is especially suitable for rapid inspection of batch products.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
