The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] This embodiment provides an ultrasonic scanning automatic jig, which can perform automatic batch ultrasonic scanning on parts to be inspected to detect whether the parts to be inspected have defects, thereby preventing unqualified products from entering the market.

[0033] like Figures 1 to 4As shown, the ultrasonic scanning automatic jig includes a support member 1, a jig base plate 2, a jig cover plate 3, a clamping mechanism 4 and a pressing mechanism 5. The jig base plate 2 is provided on the support member 1, and a placement groove is provided on the jig base plate 2, which is used to place the part to be detected 6, and then the position of the part to be detected 6 is standardized by the placement groove to facilitate ultrasonic scanning of the part to be detected 6. Among them, the jig base plate 2 and the support member 1 are detachably connected to facilitate the staff to replace the jig base plate 2, so that the ultrasonic scanning automatic jig can be applied to different types of parts to be detected 6. At the same time, the jig cover plate 3 can be covered on the jig base plate 2, so that the jig base plate 2 and the jig cover plate 3 can clamp the part to be detected 6. Optionally, the part to be detected 6 is an IGBT module. Of course, the part to be detected 6 can also be other devices that can be ultrasonically scanned using the ultrasonic scanning automatic jig, and this embodiment is not specifically limited.

[0034] Furthermore, the clamping mechanism 4 is arranged at intervals above the jig base plate 2, and is used to clamp the jig cover plate 3 and move the jig cover plate 3 onto the jig base plate 2, thereby realizing the automation of moving the jig cover plate 3. At the same time, the pressing mechanism 5 is used to press the jig cover plate 3 onto the jig base plate 2, thereby realizing the automation of clamping the jig base plate 2 and the jig cover plate 3 to the part to be inspected 6. Therefore, the ultrasonic scanning automatic jig can realize automated batch operation and improve the inspection efficiency of the part to be inspected 6, avoiding the debugging difficulties when manually sealing the part 6 by manual means. Among them, the pressing mechanism 5 is arranged on the support member 1. Optionally, the support member 1 is a water tank, so that the jig base plate 2 can be installed in the groove of the water tank, and the pressing mechanism 5 can be installed on the wall of the water tank to facilitate the ultrasonic scanning automatic jig to perform ultrasonic scanning on the part to be inspected 6. Further optionally, the water tank is a transparent tank, so that it is convenient for the staff to observe the part to be inspected 6 through the transparent tank and to grasp the inspection status of the part to be inspected 6 at any time.

[0035] like Figures 1 to 3As shown, the pressing mechanism 5 includes a connecting frame 51, a pressing module 52 and a first horizontal moving component 53. The driving end of the first horizontal moving component 53 is connected to one end of the connecting frame 51 so that the first horizontal moving component 53 can drive the connecting frame 51 to move in the horizontal direction, and the other end of the connecting frame 51 is connected to the pressing module 52, so that the pressing module 52 can also move in the horizontal direction through the drive of the connecting frame 51, thereby adjusting the position of the pressing module 52 in the horizontal direction, making it easier for the pressing module 52 to press down the jig cover 3. Among them, the first horizontal moving component 53 is arranged on the support member 1, so that relative displacement can occur between the support member 1 and the connecting frame 51 in the horizontal direction. Optionally, the connecting frame 51 is an L-shaped bracket, one end of the L-shaped bracket is connected to the driving end of the first horizontal moving component 53, and the other end of the L-shaped bracket is connected to the pressing module 52. Further optionally, the first horizontal moving component 53 is a slide cylinder.

[0036] Furthermore, the pressing module 52 includes a first vertical moving component 521 and a pressing member 522. The first vertical moving component 521 is provided on the connecting frame 51, so that the first vertical moving component 521 can move in the horizontal direction under the drive of the connecting frame 51. The driving end of the first vertical moving component 521 is connected to the pressing member 522, so that the first vertical moving component 521 can drive the pressing member 522 to move in the vertical direction, so that the pressing member 522 can be used to press down the jig cover plate 3, so as to press the jig cover plate 3 tightly against the jig base plate, thereby achieving the clamping of the jig cover plate 3 and the jig base plate 2 on the to-be-tested part 6. Among them, the position of the pressing member 522 in space can be adjusted by the first horizontal moving component 53 and the first vertical moving component 521, so as to ensure that the pressing member 522 can press down the jig cover plate 3, and at the same time, when the clamping mechanism 4 moves the jig cover plate 3 onto the jig base plate 2, it can avoid the pressing member 522 from interfering with the movement of the jig cover plate 3. Optionally, the first vertical moving component 521 is a slide cylinder.

[0037] Furthermore, a pressing portion 5221 is provided on the pressing member 522, and a first slot 31 is provided on the jig cover 3. The pressing portion 5221 can be inserted into the first slot 31 in the vertical direction, thereby enhancing the horizontal stability of the pressing member 522 and the jig cover 3, and preventing the jig cover 3 from being misaligned with the jig base 2 when the pressing member 522 presses the jig cover 3. Optionally, the pressing mechanism 5 includes two pressing mechanisms 5, which are arranged opposite to each other in the horizontal direction, so that the pressing mechanisms 5 can press the jig cover 3 from opposite sides to ensure the accuracy of the mutual cooperation between the jig cover 3 and the jig base 2.

[0038] like Figures 1-2As shown, the gripping mechanism 4 includes a second vertical moving assembly 41 and a gripping module 42, and the gripping module 42 is connected to the driving end of the first vertical moving assembly 521, so that the second vertical moving assembly 41 can drive the gripping module 42 to move in the vertical direction, thereby enabling the gripping module 42 to drive the jig cover 3 to move in the vertical direction, thereby adjusting the relative position between the jig cover 3 and the jig base 2 to achieve automated batch operation. Optionally, the second vertical moving assembly 41 is a slide cylinder.

[0039] Furthermore, the clamping module 42 includes a support frame 421, a second horizontal moving assembly 422, and a clamping member 423. The support frame 421 is arranged at the driving end of the second vertical moving assembly 41, and the second horizontal moving assembly 422 is arranged on the support frame 421, so that the second vertical moving assembly 41 can drive the support frame 421 to move in the vertical direction. Further, the support frame 421 can drive the second horizontal moving assembly 422 to move in the vertical direction. Among them, by providing the support frame 421, interference between the second vertical moving assembly 41 and the second horizontal moving assembly 422 can be avoided. At the same time, the driving end of the second horizontal moving assembly 422 is connected to the clamping member 423, so that the second horizontal moving assembly 422 can drive the clamping member 423 to move in the horizontal direction, and then the clamping member 423 can be used to clamp the jig cover 3, thereby realizing the displacement of the jig cover 3 in space. Optionally, the second horizontal moving assembly 422 is a clamping cylinder.

[0040] Furthermore, the clamping member 423 is provided with a clamping portion 4231, and the jig cover plate 3 is provided with a second slot 32. The clamping portion 4231 can be inserted into the second slot 32 in the horizontal direction, thereby enabling the clamping member 423 to clamp the jig cover plate 3. Specifically, two clamping members 423 are provided, and the two clamping members 423 are arranged opposite each other in the horizontal direction. The two clamping members 423 can be relatively displaced by the second horizontal moving assembly 422 in the horizontal direction, so that the clamping portions 4231 on the two clamping members 423 can be inserted into the second slot 32 of the jig cover plate 3, thereby achieving the fixation of the clamping members 423 to the jig cover plate 3.

[0041] like Figure 4 As shown, the ultrasonic scanning automatic jig also includes a seal 7, which is provided between the jig base plate 2 and the jig cover plate 3 and is used to seal the gap between the jig base plate 2 and the jig cover plate 3 to prevent external liquid from flowing into the space formed after the jig cover plate 3 and the jig base plate 2 are matched. At the same time, the jig cover plate 3 is pressed down by the pressing mechanism 5, which can improve the sealing effect of the seal 7. Optionally, a seal 7 is also provided between the part to be inspected 6 and the jig cover plate 3. Further optionally, the seal 7 is a rubber sealing ring, and the deformation of the rubber sealing ring achieves a sealing and waterproof effect.

[0042] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
