[0035] The following is for reference. Figures 1 to 4 A testing device according to a first aspect of the present invention will be described in detail.

[0036] refer to Figure 1 and Figure 2 A testing device according to an embodiment of the present invention includes a frame 100, a positioning module 200, a first testing module 300, and a detection module 400. The positioning module 200 is disposed on the frame 100 and is used to position the workpiece. The first testing module 300 is disposed on the frame 100 and includes a first driving structure 310 and a first pushing member 320. The first driving structure 310 is connected to the first pushing member 320 and is used to drive the first pushing member 320 to move along a first horizontal direction, so as to actuate a first spring piece on the workpiece along the first horizontal direction through the first pushing member 320. The detection module 400 is disposed on the frame 100 and is used to detect whether the first spring piece has fallen off the workpiece.

[0037] In the operation of the testing device of this application, the welded workpiece is first placed on the positioning module 200 to fix it. Then, the first driving structure 310 drives the first pushing member 320 to move along the first horizontal direction, so that the first pushing member 320 actuates the first spring piece on the workpiece in the first horizontal direction. Then, the detection module 400 detects whether the actuated first spring piece has fallen off the workpiece, thereby detecting whether the weld of the first spring piece on the workpiece is firm. From the above operation process, it can be seen that the testing device of this application can detect the firmness of the weld of the first spring piece on the workpiece through the cooperation of the first testing module 300 and the detection module 400.

[0038] refer to Figure 2 In some embodiments of this utility model, the first pushing member 320 is provided with a hook-shaped portion 321 for abutting against the first spring piece. The first driving structure 310 is located on one side of the positioning module 200 in the first horizontal direction. Under the drive of the first driving structure 310, the hook-shaped portion 321 can drive the first spring piece to approach the first driving structure 310 along the first horizontal direction. It can be understood that by driving the first pushing member 320 to move along the first horizontal direction through the first driving structure 310, so that the hook-shaped portion 321 on the first pushing member 320 abuts against the first spring piece, and then driving the first pushing member 320 to continue to move along the first horizontal direction, the hook-shaped portion 321 on the first pushing member 320 can drive the first spring piece and the hook-shaped portion 321 to move away from the workpiece in the same direction, so as to actuate the first spring piece on the workpiece.

[0039] like Figure 2 As shown, in some embodiments, the first test module 300 further includes a first position adjustment structure 330, which is drivenly connected to the first pusher 320 and is used to adjust the position of the first pusher 320 in a second horizontal direction, wherein the second horizontal direction intersects with the first horizontal direction. Understandably, after the workpiece is placed on the positioning module 200, the position of the first pusher 320 in the second horizontal direction is adjusted by the first position adjustment structure 330 so that the first pusher 320 can be misaligned with the first spring on the workpiece in the second horizontal direction. Then, the first drive structure 310 drives the first pusher 320 to approach the workpiece in the first horizontal direction so that the hook-shaped part 321 on the first pusher 320 moves to the side of the first spring away from the first drive structure 310. Next, the first position adjustment structure 330 adjusts the position of the first pusher 320 in the second horizontal direction so that the hook-shaped part 321 is aligned with the first spring in the second horizontal direction. Then, under the drive of the first drive structure 310, the hook-shaped part 321 can drive the first spring to approach the first drive structure 310 in the first horizontal direction to complete the flicking of the first spring.

[0040] In some embodiments of this utility model, the first test module 300 includes a plurality of first pushing members 320 distributed along a second horizontal direction. It is understood that by providing a plurality of first pushing members 320, the first test module 300 of this application can complete the actuation of the first springs on multiple workpieces in a single operation.

[0041] refer to Figure 2 In some embodiments of this utility model, the test module further includes an elastic structure 340. The first pusher 320 is connected to the first drive structure 310 through the elastic structure 340. The elastic structure 340 can deform in the first horizontal direction to provide elastic force along the first horizontal direction and to provide elastic force for the first pusher 320 to maintain contact with the first spring piece. It can be understood that by connecting the first pusher 320 and the first drive structure 310 with the elastic structure 340, when the first pusher 320 moves in the horizontal direction under the drive of the first drive structure 310 and the first pusher 320 contacts the first spring piece, the elastic structure 340 can provide the first pusher 320 with a contact force that always maintains contact with the first spring piece, while reducing the possibility of the first pusher 320 causing the first spring piece to deform. Furthermore, the setting of the elastic structure 340 ensures that the force applied by the first pusher 320 to the first spring piece can be kept within a certain range, avoiding excessive force applied by the first pusher 320 to the first spring piece, which could cause the first spring piece to fall off the workpiece.

[0042] like Figure 2 As shown, in some embodiments, the first driving structure 310 includes a mounting base 311 and a first driver 312 connected to each other. The first driver 312 can drive the mounting base 311 to move along a first horizontal direction. The first pusher 320 is slidably disposed on the mounting base 311 along the first horizontal direction. The elastic structure 340 includes a spring, with one end of the spring away from the positioning module 200 connected to the first pusher 320, and the other end of the spring near the positioning module 200 connected to the mounting base 311. It can be understood that by driving the mounting base 311 to move along the first horizontal direction through the first driver 312, the first pusher 320 on the mounting base 311 moves along the first horizontal direction. When the first pusher 320 abuts against the first spring, the first spring provides resistance to the first pusher 320 to continue moving along the first horizontal direction. Since the two ends of the spring connect the first pusher 320 and the mounting base 311, the spring is compressed to provide the first pusher 320 with the elastic force to continue abutting against the first spring.

[0043] refer to Figure 3In some embodiments of this utility model, the testing device further includes a second testing module 500. The second testing module 500 includes a second driving structure 510 and a second pushing member 520. The second driving structure 510 is connected to the second pushing member 520 and is used to drive the second pushing member 520 to move vertically, so as to actuate the second spring piece on the workpiece vertically. The detection module 400 is used to detect whether the second spring piece has fallen off the workpiece. It can be understood that the workpiece will have a first spring piece and a second spring piece welded on it at the same time. After the positioning module 200 fixes the workpiece, the second driving structure 510 drives the second pushing member 520 to move vertically, so that the second pushing member 520 actuates the second spring piece on the workpiece vertically. Then, the detection module 400 detects whether the actuated second spring piece has fallen off the workpiece, so as to detect whether the welding of the second spring piece on the workpiece is firm.

[0044] like Figure 3 As shown, in some embodiments, the second test module 500 further includes a second position adjustment structure 530, which is drivenly connected to the second pusher 520 and is used to adjust the position of the second pusher 520 in the horizontal direction. It is understood that the second position adjustment structure 530 adjusts the horizontal position of the second pusher 520 so that the second pusher 520 can be aligned with the second spring in the horizontal direction, and then the second test module 500 tests the firmness of the second spring.

[0045] Specifically, the second position adjustment structure 530 is used to adjust the position of the second pusher 520 in the first horizontal direction.

[0046] refer to Figure 1In some embodiments of this utility model, the positioning module 200 includes a lifting mechanism 210 and a clamping mechanism 220. The lifting mechanism 210 includes a second driver 211 and a lifting member 212 connected to each other. The lifting member 212 is located below the clamping mechanism 220. A receiving area for accommodating the fixture 600 is formed between the lifting member 212 and the clamping mechanism 220. Under the drive of the second driver 211, the lifting member 212 can drive the fixture 600 in the receiving area to move upward and closer to the clamping mechanism 220, so that the clamping mechanism 220 can cooperate with the fixture 600 to position the workpiece on the fixture 600. Understandably, the second driver 211 drives the lifting member 212 on the lower side of the clamping mechanism 220 to move upward, so that the lifting member 212 drives the fixture 600 located in the receiving area to move upward and approach the clamping mechanism 220, and the fixture 600 cooperates with the clamping mechanism 220 to clamp the workpiece on the fixture 600. Then, the first test module 300 tests the firmness of the first spring on the workpiece. After the test of the first spring is completed, the second driver 211 drives the lifting member 212 to move downward, so that the lifting member 212 drives the fixture 600 to move downward. At this time, the fixture 600 can be taken out from the receiving area.

[0047] The following is for reference. Figure 1 and Figure 4 A welding device according to a second aspect embodiment of the present invention will be described in detail.

[0048] refer to Figure 4 A welding apparatus according to a second aspect embodiment of the present invention includes a testing device as described in the first aspect embodiment. By employing a testing device from the first aspect embodiment in the welding apparatus, the firmness of the welding of the first spring clip on the workpiece can be detected through the cooperation of the first testing module 300 and the detection module 400.

[0049] like Figure 1 and Figure 4 As shown, in some embodiments, the welding equipment further includes a transfer device 700, which includes a drive module 710 and a turntable 720 connected to each other. A fixture 600 is slidably provided on the turntable 720 in the vertical direction. A connecting structure 610 is provided on the fixture 600. Under the drive of the drive module 710, the turntable 720 can rotate to drive the fixture 600 into or out of the receiving area. When the fixture 600 is in the receiving area, the connecting structure 610 is detachably connected to the lifting member 212.

[0050] Understandably, the drive module 710 in the transfer device 700 drives the turntable 720 to rotate, so that the turntable 720 drives the fixture 600 to rotate into the receiving area, and connects the connecting structure 610 of the fixture 600 to the lifting member 212. Then, the second driver 211 drives the lifting member 212 to move upward, so that the lifting member 212 drives the fixture 600 to move upward in the vertical direction, and then clamps the workpiece with the clamping mechanism 220. After the first test module 300 tests the firmness of the first spring on the workpiece, the second driver 211 drives the lifting member 212 to move downward, so that the lifting member 212 drives the fixture 600 to move downward in the vertical direction. Then, the drive module 710 drives the turntable 720 to continue to rotate, so that the fixture 600 is removed from the receiving area and the connecting structure 610 is separated from the lifting member 212.
