Description

Technical Field

[0001] This invention relates to the field of automated production equipment technology, and in particular to a sealing mechanism and a helium detection device. Background Technology

[0002] As a key component of circular power / energy storage batteries, cylindrical aluminum shells may have defects during the molding process and when the explosion-proof valve (groove) is made on the surface of the aluminum shell. These defects can lead to the finished battery failing to meet sealing requirements and affecting battery safety. Therefore, after the cylindrical aluminum shell is formed, it is necessary to test its sealing performance with helium gas. The industry commonly uses a sealing ring / gasket to press against the two end faces of the aluminum shell for helium gas testing.

[0003] However, because the aluminum shell itself is relatively thin, the sealing ring is prone to damage, crushing, and short lifespan during testing, resulting in frequent replacement of the sealing ring and poor test stability. Summary of the Invention

[0027] This invention provides a sealing mechanism. The sealing mechanism is used to seal a workpiece 300 to be tested. The sealing mechanism includes a mold 100 and a sealing assembly 200. The mold 100 has a cavity 110, and the workpiece 300 to be tested is disposed in the cavity 110 along the width direction of the cavity 110. The sealing assembly 200 includes a first driving member 210, a pull rod 220, and a sealing member 230. The first driving member 210 is disposed on the side of the mold 100 opposite to the workpiece 300 to be tested, with the driving end of the first driving member 210 facing the workpiece 300 to be tested. The pull rod 220 has a first end 221 and a second end 222. The first end 221 is connected to the driving end of the first driving member 210, and the second end 222 passes through the mold 100 and is located inside the mold cavity 110. The sealing member 230 is sleeved on the second end 222. When the first driving member 210 is extended, the second end 222 is inserted into the workpiece 300 to be tested, and the sealing member 230 abuts against the workpiece 300 to be tested. When the first driving member 210 is retracted, the second end 222 is separated from the workpiece 300 to be tested.

[0028] like Figure 1 and Figure 2As shown, the mold 100 has a cuboid structure. A mold cavity 110 is provided in the middle of the mold 100. The mold cavity 110 is used to place the workpiece 300 to be tested. The workpiece 300 to be tested is cylindrical. The workpiece 300 to be tested is arranged along the width direction of the mold 100.

[0029] like Figure 1 and Figure 2 As shown, the mold 100 has a length direction and a width direction. The length direction of the mold 100 is the radial extension direction of the workpiece 300 to be tested, and the width direction of the mold 100 is the axial extension direction of the workpiece 300 to be tested.

[0030] Multiple parts to be inspected 300 are arranged in the mold cavity 110 along the length of the mold 100. Product separators are provided between adjacent parts to be inspected 300. The product separators can limit the position of the parts to be inspected 300 in the mold cavity 110.

[0031] The product separator has a cuboid structure. The sidewall of the product separator abuts against the outer wall of the part to be tested 300 to prevent the part to be tested 300 from shifting position due to the shaking of the mold 100 during operation, which would affect the test results.

[0032] A product positioning block is provided at one end of the product separator within the mold cavity 110. Two product positioning blocks are positioned on opposite sides of the workpiece 300 to be inspected. These two product positioning blocks are arranged radially along the workpiece 300 to define its position along its length within the mold cavity 110. The product separator provides both coarse and fine positioning of the workpiece 300, preventing the mold 100 from shaking during operation and causing the workpiece 300 to shift within the mold cavity 110, thus affecting the inspection results.

[0033] The sealing assembly 200 also includes a tie rod cylinder fixing plate and a cylinder connecting rod. The tie rod cylinder fixing plate is a rectangular plate with a through hole for the drive end of the first drive member 210 to pass through.

[0034] Of course, the shape of the tie rod cylinder fixing plate is not limited to the above structure. The tie rod cylinder fixing plate can also be a circular plate or other structures.

[0035] One end of the cylinder connecting rod is connected to the outer wall of the mold 100, and the other end is connected to one side of the tie rod cylinder fixing plate. The tie rod cylinder fixing plate is fixed to the mold 100 by the cylinder connecting rod. The first driving component 210 is a tie rod cylinder. The driving end of the tie rod cylinder protrudes through the through hole of the tie rod cylinder fixing plate.

[0036] There are four cylinder connecting rods. The four cylinder connecting rods are respectively connected to the four corners of the tie rod cylinder fixing plate to strengthen the connection stability between the tie rod cylinder fixing plate and the mold 100.

[0037] The pull rod 220 is located between the four cylinder connecting rods. The first end 221 of the pull rod 220 is connected to the driving end of the first driving member 210, and the second end 222 of the pull rod 220 passes through the mold 100 and extends into the mold cavity 110.

[0038] Of course, the number and position of the cylinder connecting rods are not limited to those mentioned above. The number of cylinder connecting rods can also be three, five, etc.

[0039] like Figure 3 As shown, the pull rod 220 is cylindrical. The sealing element 230 fitted onto the second end 222 of the pull rod 220 is annular. The sealing element 230 is an elastic sealing ring such as a rubber ring.

[0040] With the drive end of the first drive member 210 extended, the second end 222 of the pull rod 220 is inserted into the test piece 300, and the sealing member 230 fitted on the second end 222 abuts against the test piece 300, thereby sealing the test piece 300.

[0041] When the drive end of the first drive member 210 is retracted, the second end 222 of the pull rod 220 is separated from the test piece 300, and the seal 230 is sleeved on the second end 222. The seal 230 moves away from the test piece 300 with the pull rod 220, and the test piece 300 is in an open state at this time.

[0042] In this embodiment of the invention, the first driving member 210 drives the pull rod 220 to be inserted into the test piece 300, so that the sealing member 230 sleeved on the pull rod 220 abuts against the test piece 300, thereby achieving a seal on the test piece 300; the first driving member 210 drives the pull rod 220 to retract, so that the sealing member 230 is separated from the test piece 300, so as to facilitate the removal or replacement of the test piece 300 in the mold cavity 110 and improve the efficiency of test piece replacement.

[0043] By using product separator blocks and product positioning blocks, coarse and fine positioning of the part to be inspected 300 can be achieved, thereby improving the accuracy of the connection position between the part to be inspected 300 and the mold 100, reducing inspection errors, and improving inspection efficiency.

[0044] Optionally, the sealing assembly 200 further includes a pull ring 240, which is connected to the first drive member 210 and the first drive member 210 is connected to the pull rod 220 via the pull ring 240.

[0045] like Figure 2As shown, the pull ring 240 has a cuboid structure. A through hole is provided on the pull ring 240 along the extension direction of the driving end of the first driving member 210. The first driving member 210 drives the pull ring 240, causing the pull rod 220 to extend and retract.

[0046] Optionally, the sealing assembly 200 also includes a floating head 250, which is disposed on the side of the mold 100 near the pull ring 240. The floating head 250 is connected to the first end 221, and the first drive member 210 is connected to the first end 221 through the pull ring 240 and the floating head 250.

[0047] like Figure 2 As shown, the pull ring 240 is floatingly connected to the floating head 250, which is locked to the drive end of the pull rod cylinder. The first end 221 of the pull rod 220 is connected to the first drive member 210 through the floating head 250 and the pull ring 240. When the first drive member 210 is activated, it drives the pull ring 240, which in turn drives the floating head 250, thereby causing the pull rod 220 to insert into the workpiece 300 to be tested, or to separate the pull rod 220 from the workpiece 300 to be tested.

[0048] Optionally, the sealing assembly 200 also includes a limiting buffer 260, one end of which is connected to the pull ring 240, and the other end of the limiting buffer 260 away from the pull ring 240 is connected to the floating head 250.

[0049] like Figure 1 and Figure 2 As shown, the limit buffer 260 is disposed between the pull ring 240 and the floating head 250. The limit buffer 260 is fixed on the pull ring 240 to limit the extension or retraction stroke of the pull rod 220, so as to avoid excessive extension or retraction affecting the connection accuracy between the pull rod 220 and the test piece 300.

[0050] Optionally, the sealing assembly 200 also includes a flange sleeve 270, one end of which is connected to the inner wall of the mold 100, and the second end 222 of the tie rod 220 extends out of the flange sleeve 270.

[0051] like Figure 1 and Figure 2 As shown, the sealing assembly 200 also includes a flange sleeve 270 and a stainless steel bushing 280. The stainless steel bushing 280 is fitted onto the end of the workpiece 300 to be tested. The flange sleeve 270 is connected to the mold 100. The second end 222 of the pull rod 220 passes through the flange sleeve 270 and is located inside the mold cavity 110. The flange sleeve 270 fixes the position of the pull rod 220 within the mold cavity 110 to correspond to the position of the workpiece 300 to be tested, improving the positional accuracy between the workpiece 300 and the pull rod 220 and preventing positional deviations from affecting the test results.

[0052] Optionally, the seal 230 is fitted onto the second end 222. With the first drive member 210 extended, the pull rod 220 is inserted into the test piece 300, and the seal 230 is located between the flange sleeve 270 and the stainless steel bushing 280.

[0053] like Figure 1 and Figure 2 As shown, when the pull rod 220 is inserted into the part to be tested 300, the seal 230 is located between the flange sleeve 270 and the stainless steel bushing 280. By abutting the seal 230 between the stainless steel bushing 280 and the flange sleeve 270, the sealing effect of the part to be tested 300 can be enhanced.

[0054] Optionally, the sealing mechanism further includes a drive assembly 400, which is connected to the mold 100. The drive assembly 400 includes a collection plate 410 and a second drive member 420. The collection plate 410 is disposed on the side of the mold 100 near the sealing assembly 200, and a second end 222 passes through the collection plate 410. The mold 100 is disposed within the mold cavity 110. The second drive member 420 is connected to the mold 100, and the drive end of the second drive member 420 is parallel to the extension direction of the pull rod 220. Two second drive members 420 are also included. The two second driving members 420 are positioned at relative positions along the length of the mold 100. The driving ends of the two second driving members 420 are connected to the opposite ends of the assembly plate 410. The second driving members 420 can drive the assembly plate 410 to move closer to or away from the mold 100. When the second driving members 420 are extended, the assembly plate 410 moves away from the mold 100, and the test piece 300 is in an open state. When the second driving members 420 are retracted, the side wall of the assembly plate 410 abuts against the mold 100, and the test piece 300 is in a closed state.

[0055] like Figure 1 and Figure 2 As shown, the drive assembly 400 is used to adjust the distance between the first drive member 210 and the mold 100. Second drive members 420 are provided on opposite sides along the length of the mold 100. The second drive member 420 is a telescopic cylinder. A telescopic cylinder fixing plate is connected to the drive end of the telescopic cylinder.

[0056] like Figure 1 As shown, the mold 100 has a long side and a short side. Two second driving members 420 are provided on each of the two opposite short sides of the mold 100, with the driving ends of the two second driving members 420 facing opposite directions. A collection plate 410 is provided along the long side of the mold 100. The opposite ends of the collection plate 410 are connected to the corresponding second driving members 420. The second driving members 420 can drive the collection plate 410 away from or towards the mold 100.

[0057] A sealing assembly 200 is disposed on one side of the assembly plate 410. The sealing assembly 200 is disposed opposite to the mold 100. One end of the cylinder connecting rod is connected to the tie rod cylinder fixing plate, and the other end of the cylinder connecting rod is connected to the assembly plate 410. The driving end of the first driving member 210 is connected to the first end 221 of the tie rod 220 through the pull ring 240, the limit buffer 260, and the floating head 250. The second end 222 of the tie rod 220 passes through the assembly plate 410, the flange sleeve 270, and the mold 100 in sequence and is located in the mold cavity 110.

[0058] With the second drive member 420 driving the assembly plate 410 away from the mold 100, the first drive member 210 retracts to separate the pull rod 220 from the workpiece 300 to be tested.

[0059] When the second driving member 420 is in the retracted state, the assembly plate 410 abuts against the mold 100, the driving end of the first driving member 210 extends, and the second end 222 of the pull rod 220 passes through the flange sleeve 270 and inserts into the workpiece 300 to be tested. At this time, the sealing member 230 abuts between the stainless steel bushing 280 and the flange sleeve 270. The driving end of the first driving member 210 retracts, causing the second end 222 of the pull rod 220 to exit the workpiece 300 to be tested. At this time, the stainless steel bushing 280 fitted on the workpiece 300 and the flange sleeve 270 abut against each other through the sealing member 230, so that the workpiece 300 to be tested is in a sealed state.

[0060] Optionally, when the assembly plate 410 abuts against the mold 100, the driving end of the first driving member 210 retracts, and the sealing member 230 abuts between the test piece 300 and the inner wall of the mold cavity 110.

[0061] like Figure 1 and Figure 2 As shown, the second drive member 420 can drive the assembly plate 410 to move closer to or away from the mold 100. When the assembly plate 410 abuts against the mold 100 by the second drive member 420, and in the state where the first drive member 210 drives the pull rod 220 to retract, the seal 230 abuts between the stainless steel bushing 280 and the flange sleeve 270.

[0062] Optionally, the sealing mechanism further includes a detection component 500, which is connected to the mold 100, is disposed opposite to the sealing component 200, and is in communication with the workpiece 300 to be tested.

[0063] like Figure 1 As shown, the detection component 500 is connected to the mold 100. The detection component 500 is used to evacuate the inside of the sealed test piece 300, thereby performing an airtightness test on the test piece 300.

[0064] Optionally, the detection assembly 500 includes a vacuum device 510, which is connected to the side of the test piece 300 away from the sealing assembly 200.

[0065] like Figure 1 As shown, the vacuuming device 510 is connected to the mold 100 and is also connected to the workpiece 300 to be tested. When the workpiece 300 to be tested is in a sealed state, the vacuuming device 510 is used to evacuate the workpiece 300 to check its airtightness.

[0066] The present invention also proposes a helium detection device, including the sealing mechanism described above.

[0067] like Figure 2 As shown, the vacuum device 510 is used to evacuate the test piece 300, and helium gas is injected into the test piece 300. The leak rate of the test piece 300 is then detected by a helium detector.
