[0002] For parts bonded with glue, for example, the battery pack inside the cell and the liquid cooling plate are bonded with glue, in order to meet the use requirements, such as the connection strength and heat conduction performance requirements between the cell and the liquid cooling plate, the glue coating area must meet the design requirements. At present, the glue coating area is mainly detected by visual inspection to see whether it meets the requirements, for example, when the glue overflows, it is judged that the glue coating area meets the design requirements, and when the glue does not overflow, it cannot be judged whether the glue coating area meets the design requirements. However, due to the influence of factors such as assembly position, part flatness, glue coating precision and glue coating pressure, it is a common situation in the production process that the glue does not overflow, therefore, it is urgent to design a detection tool to judge whether the glue coating area meets the design requirements when the glue does not overflow.

[0026] 10. Colloids. Detailed Implementation

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, the adhesive application area detection fixture 100 of this embodiment includes a base 1 and a plurality of detection rods 2. The detection rods 2 are movably connected to the base 1 along the height direction of the base 1 (direction A in the figure), and the bottom end of the detection rod 2 forms a stop end 21. The plurality of detection rods 2 are arranged sequentially along the length direction of the base 1 (direction B in the figure).

[0029] like Figure 3As shown, when the glue area detection tool 100 detects the glue area, the plurality of detection rods 2 are inserted into the gap between the two components bonded by the glue 10, and the plurality of detection rods 2 are moved along the height direction of the base 1, so that the abutting end 21 of each detection rod 2 abuts against the edge of the glue 10. According to the depth of each detection rod 2 inserted into the gap and the total size of the detection assembly composed of the plurality of detection rods 2 in the length direction of the base 1, the glue-free area can be obtained. According to the area of the components bonded by the glue 10 and the obtained glue-free area, the glue area can be calculated. The glue-free area is equal to the product of the total depth of the plurality of detection rods 2 inserted into the gap and the size of the detection assembly in the length direction of the base 1; the area of the components bonded by the glue 10 can be calculated according to the size of the components themselves; and the glue area is equal to the difference between the area of the components bonded by the glue and the obtained glue-free area. Then, the obtained glue area is compared with the standard preset area to determine whether the glue area meets the requirements. For example, when the obtained glue area is greater than or equal to the standard preset area, it is determined that the glue area meets the requirements, and when the obtained glue area is less than the standard preset area, it is determined that the glue area does not meet the requirements.

[0030] The size of the detection assembly in the length direction of the base 1 refers to the sum of the total size of all detection rods 2 in the length direction of the base 1 and the total spacing of adjacent detection rods 1 in the length direction of the base 1. For example, the number of detection rods 2 inserted into the gap is 12, the size of a single detection rod 2 in the length direction of the base 1 is d1, the spacing of adjacent two detection rods 2 in the length direction of the base 1 is d2, and the size of the detection assembly in the length direction of the base 1 is d0, then d0 = 12*d1 + 11*d2. It should be noted that the spacing between adjacent detection rods 2 can be 0.

[0031] The two components bonded by the glue 10 can be a battery cell and a liquid cooling plate. When the glue area detection tool 100 detects the glue area, the detection rod 2 is inserted into the gap between the battery cell and the liquid cooling plate.

[0032] The depth of the detection rod 2 inserted into the gap is the distance between the edge of the glue 10 and the edge of the component. Let the glue-free area be S1, the area of the components bonded by the glue 10 be S2, and the glue area be S3, then S3 = S2-S1.

[0033] In specific embodiments, the number of detection times of the glue area detection tool 100 is set according to the specific size of the glue body 10. For example, when the length of the glue body 10 is large and the width of the glue body 10 at different positions needs to be detected, a plurality of detection zones can be divided along the length direction of the glue body 10, and the glue area detection tool 100 is used to detect each detection zone. Among them, the larger the length of the glue body 10, the more detection zones are divided, and the more detection times are needed; the shorter the length of the glue body 10, the fewer detection zones are divided, and the fewer detection times are needed. The total unglued area is obtained by adding the unglued area of each detection zone, and the glue area of the part to which the glue body 10 is bonded is obtained by subtracting the total unglued area from the area of the part.

[0034] In some embodiments, as shown in Figures 1 to 3 , the two adjacent detection rods 2 are arranged at intervals.

[0035] As shown in Figure 3 , by arranging the two adjacent detection rods 2 at intervals, the mutual interference or overlap of the detection rods 2 when moving along the height direction of the base 1 can be avoided, which is beneficial to improve the detection efficiency and improve the production efficiency of the product. Among them, the product can be a battery pack including a liquid cooling plate and a battery cell, or other products bonded by the glue body 10.

[0036] Optionally, the base 1 is provided with a plurality of spacing portions 12, and the plurality of spacing portions 12 are arranged at intervals along the length direction of the base 1. The spacing portion 12 is arranged between the two adjacent detection rods 2. Among them, the spacing portion 12 can be a spacing plate, a spacing block, a spacing rod, etc.

[0037] By arranging the spacing portion 12, the two adjacent detection rods 2 can be spaced apart, which can more effectively avoid the mutual interference or overlap of the detection rods 2 when moving along the height direction of the base 1, thereby further improving the detection efficiency and further improving the production efficiency of the product.

[0038] In some embodiments, as shown in Figure 4 and Figure 5 , the base 1 is provided with a through hole 13 extending along the height direction thereof, and the detection rod 2 is slidably inserted into the through hole 13 along the height direction of the base 1.

[0039] By arranging the through hole 13 on the base 1 and slidably inserting the detection rod 2 into the through hole 13, the hole wall of the through hole 13 can be used to limit the detection rod 2 during the movement of the detection rod 2 along the height direction of the base 1, preventing the detection rod 2 from being deflected during the movement. Thus, the detection accuracy can be improved, and the qualification rate of the product can be improved.

[0040] Optionally, the base 1 comprises a first frame 101 and a second frame 102, the first frame 101 and the second frame 102 are arranged in a spaced manner along the height direction of the base 1 and are connected, and the first frame 101 and the second frame 102 are each provided with a through hole 13.

[0041] It can be understood that the greater the depth of the through hole 13, that is, the greater the size of the through hole 13 in the height direction of the base 1, the better the limiting effect of the hole wall of the through hole 13 on the detection rod 2, and the higher the detection precision of the glue application area detection tool 100. The greater the depth of the through hole 13, the more difficult it is to ensure the machining precision.

[0042] By arranging the base 1 to comprise the first frame 101 and the second frame 102 arranged in a spaced manner along the height direction thereof, and arranging the through hole 13 on each of the first frame 101 and the second frame 102, the limiting effect on the detection rod 2 can be ensured, and the detection precision of the glue application area detection tool 100 can be improved, in the case that the depth of a single through hole 13 is small and the machining precision is easy to ensure.

[0043] Of course, in other embodiments, the base 1 can also comprise only one frame, and the depth of the through hole 13 is set to be large to better limit the detection rod 2 by the through hole 13.

[0044] Optionally, as shown in Figure 4 , the surface of the detection rod 2 is provided with a height scale line 24. The height scale line 24 can be understood as a scale line for indicating height.

[0045] The distance between the starting section of the height scale line 24 and the top of the detection rod 2 can be 5 mm, and the distance between two adjacent scale lines in the height scale line 24 can be 0.5 mm.

[0046] By arranging the height scale line 24 on the surface of the detection rod 2, after the abutting end 21 of the detection rod 2 abuts against the edge of the glue body 10, the depth of the detection rod 2 inserted into the gap can be obtained by the position indicated by the height scale line 24, so that the depth of the detection rod 2 inserted into the gap can be obtained conveniently, and thus the glue application area can be obtained conveniently. Therefore, the detection efficiency can be further improved, and the production efficiency of the product can be improved.

[0047] In some embodiments, as shown in Figure 5 , the detection rod 2 is provided with a locking portion 22, and the base 1 is provided with a locking mechanism (not shown in the figure), and the locking mechanism is in locking cooperation with the locking portion 22.

[0048] When the glue area detection tool 100 detects the glue area, the stop end 21 of the detection rod 2 stops against the edge of the glue body 10, the locking mechanism is locked with the locking portion 22 to prevent the detection rod 2 from moving along the height direction of the base 1. Then the glue area detection tool 100 is moved to a position convenient for the detection personnel to observe, so as to facilitate the detection personnel to obtain the depth of the detection rod 2 inserted into the gap. In this way, the detection efficiency can be further improved, and the production efficiency of the product can be improved.

[0049] Of course, in other embodiments, the detection rod 2 can also not be provided with the locking portion 22, and the base 1 is not provided with the locking mechanism. At this time, after the stop end 21 of the detection rod 2 stops against the edge of the glue body 10, the detection rod 2 can be clamped on the base 1 by using the clamping piece to prevent the detection rod 2 from moving along the height direction of the base 1. The clamping piece can be a clip.

[0050] Optionally, as shown in Figure 5 The locking mechanism includes a locking piece, and the locking piece is rotationally connected with the base 1. The locking piece is provided with a locking protrusion, and the locking protrusion is locked with the locking slot 221. The locking piece is in the form of a flip cover.

[0051] For example, the locking piece is hinged with the base 1. When it is necessary to fix the position of the detection rod 2, the locking protrusion is inserted into and locked with the locking slot 221 by rotating the locking piece. When it is necessary to move the detection rod 2, the locking protrusion is moved out of the locking slot 221 by rotating the locking piece.

[0052] By providing the locking portion 22 with the plurality of locking slots 221 and providing the locking piece with the locking protrusion locked with the locking slot 221, the structure of the locking portion 22 and the locking mechanism is simple, and the operation is convenient. Therefore, not only the processing and manufacturing of the glue area detection tool 100 are facilitated, but also the detection efficiency is improved.

[0053] Optionally, one of the locking piece and the detection rod 2 is provided with a locking hole, and the other of the locking piece and the detection rod 2 is provided with a locking column. When the locking protrusion is locked with the locking slot 221, the locking column is inserted into and locked with the locking hole.

[0054] For example, when the locking protrusion is locked with the locking slot 221, the locking column is in interference fit with the locking hole to prevent the locking piece from rotating relative to the base 1, so that the locking piece remains in the state of being locked with the locking portion.

[0055] A plurality of locking protrusions can be arranged on the same locking member, and each locking protrusion is used for locking cooperation with the locking portion 22 of the corresponding detection rod 2; or a plurality of locking members can be arranged, and each locking member is provided with a locking protrusion, and each locking protrusion of the locking member is used for locking cooperation with the locking portion 22 of the corresponding detection rod 2.

[0056] Optionally, as shown in Figure 5 The size of the locking portion 22 in the height direction of the base 1 is L, and L is 15mm-25mm.

[0057] For example, the size of the locking portion 22 in the height direction of the base 1 is 20mm.

[0058] By setting the size of the locking portion 22 in the height direction of the base 1 to 15mm-25mm, the detection rod 2 can be locked and positioned with the locking mechanism when moving in the range, so as to realize the locking and positioning of the detection rod 2.

[0059] In some embodiments, as shown in Figure 1 、 Figure 6 and Figure 7 The base 1 is provided with a first limiting portion 11, and the detection rod 2 is provided with a second limiting portion 23. The first limiting portion 11 is arranged on at least one side of the second limiting portion 23 in the height direction of the base 1. The projection of the second limiting portion 23 in the height direction of the base 1 at least partially overlaps the projection of the first limiting portion 11 in the height direction of the base 1.

[0060] The first limiting portion 11 is arranged on at least one side of the second limiting portion 23 in the height direction of the base 1, which can be understood as: the first limiting portion 11 is arranged on one side of the second limiting portion 23 in the height direction of the base 1; or the first limiting portion 11 is arranged on both sides of the second limiting portion 23 in the height direction of the base 1.

[0061] By arranging the first limiting portion 11 and the second limiting portion 23, when the first limiting portion 11 abuts against the second limiting portion 23, the detection rod 2 cannot continue to move in the height direction of the base 1, so as to limit the limit position of the detection rod 2 in the height direction of the base 1, and avoid the separation of the detection rod 2 and the base 1. Therefore, it is beneficial to further improve the detection efficiency and improve the production efficiency of the product.

[0062] Optionally, as shown in Figure 2 and Figure 7 The detection rod 2 is provided with a limiting protrusion 231, the limiting protrusion 231 protrudes from the base 1 in the width direction (C direction in the figure) of the base 1, and the limiting protrusion 231 forms the second limiting portion 23.

[0063] By setting the limiting protrusion 231 as the second limiting part 23, the structure of the detection rod 2 is simple, and the processing and manufacturing of the detection rod 2 are facilitated, thereby facilitating the processing and manufacturing of the glue application area detection tool 100.

[0064] Optionally, a projection of a part of the hole wall of the through hole 13 in the height direction of the base 1 at least partially overlaps with a projection of the limiting protrusion 231 in the height direction of the base 1. The part of the hole wall of the through hole 13 forms the first limiting part 11.

[0065] By setting a part of the hole wall of the through hole 13 as the first limiting part 11, the structure of the base 1 is simplified, and the processing and manufacturing of the base 1 are facilitated, thereby facilitating the processing and manufacturing of the glue application area detection tool 100.

[0066] Optionally, the number of the second limiting parts 23 is two, and the two second limiting parts 23 are respectively arranged on the two sides of the first limiting part 11 in the height direction of the base 1.

[0067] For example, the first limiting part 11 is arranged on the first frame body 101, and the second limiting parts 23 are arranged on the two sides of the first frame body 101 in the height direction of the base 1.

[0068] By setting two second limiting parts 23, the limit positions of the movement of the detection rod 2 in the two directions towards and away from the abutting end 21 can be limited, and the separation of the detection rod 2 from the base 1 can be more effectively avoided.

[0069] Optionally, the second limiting part 23 close to the abutting end 21 is a bottom end limiting part, and the second limiting part 23 away from the abutting end 21 is a top end limiting part. The end surface of the top end limiting part away from the abutting end 21 is flush with the top surface of the detection rod 2. In other words, the end surface of the top end limiting part away from the abutting end 21 is coplanar with the top surface of the detection rod 2.

[0070] It should be noted that when the glue application area detection tool 100 performs glue application area detection, the detection personnel may need to push the detection rod 2 to move in the height direction of the base 1, that is, the detection personnel applies a pushing force towards the abutting end 21 to the top surface of the detection rod 2.

[0071] By setting the end surface of the top end limiting part away from the abutting end 21 to be flush with the top surface of the detection rod 2, the end surface of the top end limiting part away from the abutting end 21 can also be used by the detection personnel to apply the pushing force, which facilitates to increase the force application area of the detection personnel on the detection rod 2 and facilitates the detection personnel to push the detection rod 2 to move. Optionally, as Figure 1 and Figure 3As shown, the number of detection rods 2 is 12, and each detection rod 2 is composed of a single feeler gauge. The length (dimension in the A direction) of a single detection rod 2 is 45 mm, the width (dimension in the B direction) of the detection rod 2 is 3 mm, and the thickness (dimension in the C direction) of the detection rod 2 is 0.5 mm.

[0072] Optionally, the size of the glue application area detection tool 100 in the length direction of the base 1 is 50-65 mm.

[0073] For example, the size of the glue application area detection tool 100 in the B direction is 58 mm, and the spacing between two adjacent detection rods 2 is 2 mm.

[0074] The use method of the glue application area detection tool 100 of the embodiment of the present application is as follows:

[0075] After the glue solution solidifies into the glue body 10, the detection rod 2 is inserted into the gap between the two parts. During the insertion of the detection rod 2 into the gap, the abutting end 21 of the detection rod 2 is blocked by the glue body 10 after the abutting end 21 contacts the glue body 10, and the abutting end 21 cannot continue to move. The detection rod 2 continues to move in the place without the glue body 10 until the abutting end 21 contacts the glue body 10. At this time, the locking mechanism is pressed to lock the locking mechanism and the locking portion 22, and the position of the detection rod 2 is fixed. The depth of the detection rod 2 inserted into the gap is obtained through the height scale line of the detection rod 2, and the glue application area is finally obtained through calculation. Then, the obtained glue application area is compared with the standard preset area to determine whether the glue application area meets the requirements.

[0076] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and the changes, modifications, replacements and variations of the above embodiments made by those of ordinary skill in the art are within the protection scope of the present application.
