Description

Technical Field

[0001] The invention belongs to the technical field of filter assembly detection, and in particular is a component resistance welding detection device of a filter assembly. Background Art

[0002] The filter assembly is an important component of the power management of new energy vehicles. It contains several plug-in capacitors, resistors, and inductors. Currently, the "resistance welding process" is mainly used to weld these components to the main body of the filter assembly. After the welding operation is completed, the welding point must be inspected to verify the welding effect. The current detection equipment generally contacts the probe with the welding point and passes current to detect whether the welding point is completely welded. When testing different filter assemblies, due to the different welding points of different filter assemblies, and in order to enable the probe to accurately contact the welding point, the filter assembly needs to be clamped and fixed. Each inspection requires fixing, which is cumbersome. At the same time, different fixtures need to be replaced for different filter assemblies, and the replacement of the fixture requires fixing and disassembling multiple bolts, which is relatively inconvenient and needs to be improved.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 6 As shown, the present invention provides a component resistance welding detection device for a filter assembly, comprising

[0039] A shell 1, wherein a partition 2 is installed inside the shell 1;

[0040] A positioning mechanism, the positioning mechanism is arranged above the partition 2;

[0041] The fixing mechanism includes a fixing block 9, which is fixedly installed below the partition 2. A ventilation box 8 is fixedly installed between the two fixing blocks 9. A movable block 10 is movably sleeved inside the fixing block 9. The top of the movable block 10 is fixedly connected to a square tube 6. The opposite sides of the two square tubes 6 are fixedly connected to a clamping block 7.

[0042] A reset component, which is arranged inside the fixed block 9;

[0043] A guide assembly, the guide assembly is arranged above the positioning mechanism;

[0044] The boosting mechanism is arranged behind the fixing mechanism.

[0045] By adopting the above scheme, through the design of the fixing mechanism, the square tube 6 and the movable block 10 can move away from each other. When the two clamping blocks 7 are inserted into the interior of the lower tooling 4, they can be fixed. When the air pressure inside the ventilation box 8 increases, the gas will push the two movable blocks 10 to move away from each other, thereby causing the clamping block 7 to move through the square tube 6 and detach from the interior of the lower tooling 4, thereby releasing the fixing effect on it, so that the lower tooling 4 can be quickly replaced.

[0046] like Figure 2 and Figure 5 As shown, the positioning mechanism includes a fixing plate 3, a lower tooling 4 and a positioning block 5.

[0047] The fixing plate 3 is fixedly installed on the top of the partition plate 2 , the fixing plate 3 is clamped with the lower tooling 4 , and the top of the lower tooling 4 is fixedly connected with the bottom of the positioning block 5 .

[0048] By adopting the above scheme and through the design of the positioning mechanism, when the fixing plate 3 is engaged with the lower tooling 4, the fixing plate 3 can limit the lower tooling 4 so that the lower tooling 4 can only move forward, and the positioning blocks 5 are distributed near the outer contour of the filter assembly. Therefore, when the filter assembly is placed above the lower tooling 4, the positioning blocks 5 can position it so that it can only move upward, which is convenient for detecting its resistance welding joint.

[0049] like Figure 4 As shown, the reset assembly includes a flexible spring 11, one end of the flexible spring 11 is fixedly connected to the inner wall of the fixed block 9, and the other end of the flexible spring 11 is fixedly connected to the movable block 10, and the flexible spring 11 is in a compressed state.

[0050] By adopting the above scheme and through the design of the reset component, when the two movable blocks 10 move away from each other, the flexible spring 11 can push the movable block 10, so that the two square tubes 6 and the movable block 10 move toward each other as a whole to reset, so that the clamping block 7 can be re-inserted into the interior of the lower tooling 4 to fix it.

[0051] like Figure 5 As shown, the guide assembly includes a guide column 12 and a fixing box 13.

[0052] The guide column 12 is fixedly installed above the fixing plate 3 , and the fixing box 13 is fixedly installed on the top of the guide column 12 .

[0053] By adopting the above solution and through the design of the guide assembly, the guide column 12 can limit the movement of the guide bearing 18, so that the guide bearing 18 and the upper tooling 20 can move more stably.

[0054] like Figure 5 and Figure 6 As shown, the booster mechanism includes a piston block 14 and a vent pipe 15.

[0055] The piston block 14 is installed at the bottom of the inner cavity of the fixed box 13 , one end of the vent pipe 15 is fixedly connected to the fixed box 13 , and the other end of the vent pipe 15 is fixedly connected to the vent box 8 , and the piston block 14 can move upward inside the fixed box 13 .

[0056] By adopting the above solution and designing the boosting mechanism, when the piston block 14 moves upward, it will push the gas inside the fixed box 13 into the interior of the ventilation box 8 through the ventilation pipe 15, so that the two movable blocks 10 can be pushed to move in opposite directions by the increased air pressure.

[0057] like Figure 5 As shown, it also includes a driving mechanism, which is arranged below the piston block 14 and includes a pneumatic cylinder 16, a moving block 17, a guide bearing 18 and a connecting block 19.

[0058] The pneumatic cylinder 16 is arranged inside the fixed plate 3 , the pneumatic cylinder 16 is fixedly connected to the moving block 17 , the moving block 17 is fixedly connected to the guide bearing 18 , the guide bearing 18 is fixedly connected to the connecting block 19 , and the guide bearing 18 can slide outside the guide column 12 .

[0059] By adopting the above scheme and designing the driving mechanism, when the pneumatic cylinder 16 is running, the two guide bearings 18 will move upward or downward through the moving block 17. The movement of the guide bearing 18 can move the connecting block 19, thereby completing the resistance welding joint detection operation of the filter component.

[0060] like Figure 4 As shown, it also includes a detection mechanism, which is arranged in front of the driving mechanism. The detection mechanism includes an upper tooling 20, a dotting mechanism 21 and a probe 22.

[0061] The interior of the upper tooling 20 is movably connected to the exterior of the connecting block 19 . The dotting mechanism 21 is arranged at the bottom of the upper tooling 20 , and the probe 22 is arranged at the bottom of the upper tooling 20 .

[0062] By adopting the above scheme and designing the detection mechanism, when the connecting block 19 moves downward, the upper tooling 20 can move downward. The movement of the upper tooling 20 enables the dotting mechanism 21 to mark MARK points on qualified filter components, and the probe 22 will detect the resistance welding joints of the filter component components.

[0063] like Figure 4 As shown, a movable column 23 is movably sleeved inside the square tube 6 , and there are two movable columns 23 . A round rod 24 is fixedly connected to opposite sides of the two movable columns 23 , and the other end of the round rod 24 extends to the interior of the upper tooling 20 .

[0064] By adopting the above solution, through the design of the round rods 24, when the two round rods 24 are inserted into the interior of the upper tooling 20, they can be fixed, and the movable column 23 can move inside the square tube 6. When the upper tooling 20 moves upward, the movable column 23 and the round rods 24 will move upward.

[0065] like Figure 2 As shown, it also includes a limiting mechanism, which is arranged on the right side of the positioning mechanism. The limiting mechanism includes a square rod 25, a limiting block 26 and an adjusting knob 27.

[0066] The bottom of the square rod 25 is fixedly connected to the top of the partition 2 , the inside of the limit block 26 is threadedly sleeved with the outside of the adjustment knob 27 , and the limit block 26 can slide outside the square rod 25 .

[0067] By adopting the above scheme, through the design of the limit mechanism, the limit block 26 can limit the movement position of the upper tooling 20. When the adjusting knob 27 is rotated, the adjusting knob 27 can contact the square rod 25, thereby fixing the limit block 26, and the rotation of the adjusting knob 27 can be loosened, so that the operator can adjust the position of the limit block 26.

[0068] like Figure 1 As shown, a display screen 28 is installed on the top of the front of the shell 1, an indicator light 29 is set on the front of the shell 1, a test instrument 30 and an industrial computer 31 are installed inside the shell 1, a safety grating 32 is set on the left and right ends of the front of the shell 1, a defective product box 33 is installed at the bottom of the inner cavity of the shell 1, and a power switch 34 is set on the front of the shell 1.

[0069] By adopting the above scheme, the welding resistance can be automatically detected through the test instrument 30 and the industrial computer 31. The safety grating 32 can stop the operation of the equipment after detecting the obstruction, so as to protect the safety of the operator. The defective product box 33 is convenient for storing the unqualified filter component components.

[0070] The working principle and use process of the present invention:

[0071] First, the operator can use different lower tooling 4 and upper tooling 20 according to different filter components. The operator can clip the lower tooling 4 to the front of the fixed plate 3 and clip the connecting block 19 into the interior of the upper tooling 20. Then the operator can start the pneumatic cylinder 16. The operation of the pneumatic cylinder 16 will cause the moving block 17 to move downward. At this time, the flexible spring 11 in a compressed state can push the two movable blocks 10 to move toward each other. The movement of the movable block 10 will cause the square tube 6 and the movable column 23 to move. During the movement, the operator can pull the movable column 23 upward so that the round rod 24 is at the same horizontal height as the left and right ends of the upper tooling 20.

[0072] Afterwards, when the pneumatic cylinder 16 stops running, the two clamping blocks 7 can be inserted into the interior of the lower tooling 4 to fix it, the two round rods 24 can be inserted into the interior of the upper tooling 20 to fix it, and the piston block 14 will move to the bottom, and then the operator can place the filter assembly on top of the lower tooling 4 so that it is positioned by the positioning block 5, the operator can adjust and fix the position of the limit block 26 by turning the adjusting knob 27 to limit the upper tooling 20, and the operator can start the pneumatic cylinder 16, and move the upper tooling 20 downward through the connecting block 19, so that the probe 22 contacts the welding points of the components of the filter assembly, and detect them through the test instrument 30 and the industrial computer 31. When all the welding points are qualified, the dotting mechanism 21 can mark the MARK points on the filter assembly, and when it is unqualified, the operator can put the filter assembly into the unqualified product box 33.

[0073] Then, when the operator needs to replace the lower tooling 4 and the upper tooling 20, the pneumatic cylinder 16 can be started. The operation of the pneumatic cylinder 16 can push the piston block 14 upward through the moving block 17, thereby pushing the gas inside the fixed box 13 to enter the interior of the ventilation box 8 through the ventilation pipe 15. The increased air pressure can push the two movable blocks 10 to move away from each other, thereby releasing the fixation of the lower tooling 4 and the upper tooling 20.
