[0002] As a core component in electric vehicles, energy storage and other fields, the safety of battery packs is of vital importance. Among them, air tightness testing is an essential and important part of battery pack safety testing. Battery pack air tightness testing mainly tests the battery pack shell, interface, connectors, etc. to ensure that the inside of the battery pack is not contaminated or invaded by dust, water vapor and other impurities from the external environment, and to prevent safety accidents such as short circuits and explosions in the battery pack.

[0003] When the battery pack is undergoing an airtightness test, the airtightness test port on the battery pack needs to be sealed. During the sealing process, the airtightness test port positions of each battery pack of the same type differ due to consistency errors. When sealing, most traditional airtightness test heads cannot automatically adjust their positions to adapt to the positions of the airtightness test ports of the battery pack, resulting in sealing jams or failures during the automatic airtightness test, resulting in low airtightness test efficiency and failure to meet the airtightness test needs of enterprises' large-volume products.

[0028] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0029] The utility model provides an XY direction floatable airtight test inflatable plugging head, which can be installed on a three-axis motion mechanism and can achieve full-automatic plugging of the airtight test port of a product, so as to conduct an airtight test on the product.

[0030] like Figures 1 to 4 As shown, the utility model includes a blocking component and a floating component.

[0031] The above-mentioned blocking assembly includes a sliding plate 100, and the sliding plate 100 is a rectangular plate. The upper surface of the sliding plate 100 is fixed to the bottom end surface of the "I"-shaped bracket 103, and the upper surface of the bracket 103 is provided with at least one blocking head 101 and at least one guide rod 102. Among them, the blocking head 101 is used to block the airtight test port on the product, and the structure of the blocking head 101 can be designed according to the airtight test port on the product, which will not be repeated here. In the present utility model, it is defined as follows: the first direction, the X-axis direction, is along the length direction of the sliding plate 100; the second direction, the Y-axis direction, is along the width direction of the sliding plate 100.

[0032] The number of plugging heads 101 and the positional relationship between multiple plugging heads 101 can be set according to the number and position of the airtight test ports on the product. In the utility model, two plugging heads 101 are arranged along the diagonal direction of the upper surface of the bracket 103; in addition, two guide rods 102 are symmetrically arranged in another diagonal direction on the upper surface of the bracket 103, and the top surface of the guide rod 102 is higher than the top surface of the plugging head 101. When the plugging head 101 is docked with the airtight test port of the product, the guide rod 102 contacts the positioning point on the product for locating the airtight test port before the plugging head 101, which plays a role in guiding the plugging head 101 to accurately dock with the airtight test port.

[0033] The floating assembly includes a first positioning plate 200 and a second positioning plate 300 .

[0034] The two side edges of the sliding plate 100 along the X-axis direction each extend toward the first positioning plate 200 to form a side baffle, and a sliding plate slot 104 is formed at an angle between each side baffle and the bottom surface of the sliding plate 100; two first slide rails 201 are symmetrically arranged at intervals along the X-axis direction on the side of the first positioning plate 200 facing the sliding plate 100, and are compatible with the two sliding plate slots 104, and the sliding plate 100 is slidably connected to the first slide rail 201 along the X-axis direction through the sliding plate slots 104.

[0035] In addition, the sliding plate 100 is symmetrically fixed with a plurality of first adjustment members 401 with elastic reset strokes along the X-axis direction on both sides of the Y-axis direction. In the present invention, two first adjustment members 401 are fixedly fixed at intervals on the sides of each sliding plate 100 along the Y-axis direction, and the first adjustment members 401 on the two sides are symmetrically arranged one by one. The first adjustment member 401 of the present invention is a balance spring, but is not limited to this, and can play an elastic balance and reset role. At this point, when the sliding plate 100 is subjected to a driving force along the X-axis direction, it can slide relative to the first positioning plate 200 along the X-axis direction, and the sliding stroke along the X-axis direction is limited to the elastic stroke of the first adjustment member 401; when the external force disappears, the sliding plate 100 is reset under the elastic reset action of the first adjustment member 401.

[0036] Furthermore, a first connecting plate 500 is fixedly connected to both sides of the first positioning plate 200 along the Y axis, and at least one first adjusting member 401 is fixedly arranged on each first connecting plate 500. One end of each first adjusting member 401 is fixedly connected to the first connecting plate 500, and the other end is fixedly connected to the side of the sliding plate 100 along the Y axis. In the present invention, two first adjusting members 401 are symmetrically fixedly connected to each first connecting plate 500.

[0037] The two side edges of the first positioning plate 200 facing the second positioning plate 300 along the Y-axis direction respectively extend toward the second positioning plate 300, thereby forming a positioning plate side rib, and a first slide groove 202 is formed at an angle between each positioning plate side rib and the bottom surface of the first positioning plate 200; the second positioning plate 300 is symmetrically provided with second slide rails 301 on the two side edges of the upper surface of the first positioning plate 200 along the Y-axis direction, and the first positioning plate 200 is slidably connected to the second slide rail 301 along the Y-axis direction through the first slide groove 202.

[0038] When the sliding plate 100 is subjected to a driving force along the Y-axis direction, due to the connection function of the first connecting plate 500 , the first positioning plate 200 synchronously drives the sliding plate 100 to slide along the Y-axis direction relative to the second positioning plate 300 .

[0039] In addition, a plurality of second connecting plates 501 are fixedly connected to one side of the first positioning plate 200 along the X-axis direction, and each second connecting plate 501 is a mirror-image "7"-shaped plate. In the present utility model, two second connecting plates 501 are symmetrically fixedly connected to one side of the first positioning plate 200 along the X-axis direction, and the vertical rod portion of each second connecting plate 501 is fixedly connected to the side of the above-mentioned first positioning plate 200, and the horizontal head of the second connecting plate 501 is fixedly connected to a plurality of second adjusting members 402 with elastic strokes along the Y-axis direction. The second adjusting member 402 of the present utility model is a balancing spring, but is not limited thereto, and can play an elastic balancing and resetting role. One end of the second adjusting member 402 is fixedly connected to the horizontal head, and the other end is fixedly connected to the side of the second positioning plate 300. When the driving force along the Y-axis direction on the sliding plate 100 disappears, the sliding plate 100 and the first positioning plate 200 are reset accordingly under the elastic resetting action of the second adjusting member 402.

[0040] Furthermore, in order to stabilize the elastic reset function of the second adjustment member 402, a second connecting plate 501 is also fixedly provided on the second positioning plate 300. Three second adjustment members 402 are fixedly provided on the second connecting plate 501. The connection method is the same as above and will not be repeated here.

[0041] The working principle and operation process of the utility model are as follows:

[0042] When the utility model is in the initial state, the plugging head 101 is kept in the neutral position along the X-axis direction under the balanced elastic force of the first adjusting member 401, and the plugging head 101 is kept in the neutral position along the Y-axis direction under the balanced elastic force of the second adjusting member 402;

[0043] In the process of sealing the airtight test port of the product, the utility model first runs to the preset point of the product to be tested; the guide rod 102 is positioned at the positioning point of the airtight test port, and if the fixed point position of the airtight test port is consistent with the preset position, the sealing port 101 can complete the sealing of the airtight test port without the help of a floating component;

[0044] Due to the consistency error of each product of the same type, there are differences in the position of the airtight test port and the position of the airtight test port positioning point. In the face of this situation, when the utility model runs to the preset point of the product to be tested, the guide rod 102 is first positioned to contact the positioning point of the airtight test port. At this time, if the position of the positioning point of the airtight test port to be tested is inconsistent with the preset point, the force exerted on the guide rod 102 due to the product position error will guide the sliding plate 100 to float along the X-axis or Y-axis direction to correct the position of the sealing head 101, so that the sealing head 101 is aligned with the airtight test port to be tested, and then accurately sealed.

[0045] When the test is completed, the airtight test port is removed from the plugging head 101 , and the plugging head 101 is reset to the initial position under the elastic reset force of the first adjustment member 401 and the second adjustment member 402 .

[0046] Since the plugging head 101 of the utility model can automatically correct the position error caused by the inconsistent position of the airtight test port to be tested, it avoids the plugging jam or plugging failure caused by the position error of the product airtight test port during the airtightness test of large quantities of products.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
