Description

Technical Field

[0001] The utility model relates to the technical field of detection jigs, in particular to an ultrasonic scanning automatic jig. Background Art

[0002] An IGBT (Insulated Gate Bipolar Transistor) is a fully controlled, voltage-driven, composite power semiconductor device consisting of a bipolar transistor and an insulated gate field-effect transistor. It combines the advantages of high input impedance and low on-state voltage drop. An IGBT module is a modular semiconductor product consisting of an IGBT and a freewheeling diode chip, connected and packaged via a specific circuit bridge. The packaged IGBT module is directly used in devices such as inverters and uninterruptible power supplies. IGBT modules offer advantages such as energy efficiency, easy installation and maintenance, and stable heat dissipation. With the advancement of energy conservation and environmental protection concepts, these products are becoming increasingly common in the market.

[0003] IGBT modules are typically scanned and inspected using ultrasonic testing jigs to detect defects and prevent substandard products from entering the market. Existing jigs used to hold IGBT modules require manual sealing, waterproofing, and debugging, resulting in low IGBT module inspection efficiency and preventing automated batch processing. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems in the above background and to propose an automatic ultrasonic scanning jig.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: an automatic ultrasonic scanning jig, comprising a support frame, a mounting groove formed on the surface of the support frame, a mounting plate movably mounted within the mounting groove, a placement seat fixedly mounted on the side of the mounting plate, an auxiliary device provided on one side surface of the support frame, the auxiliary device comprising a U-shaped plate fixedly mounted on one side surface of the support frame, a cylinder fixedly mounted on the surface of the top horizontal end of the U-shaped plate, and a U-shaped bracket fixedly mounted on the output end of the cylinder. The provision of the cylinder serves to drive the movement of the U-shaped bracket.

[0006] Preferably, a slide bar is fixedly installed between the inner walls of both sides of the U-shaped bracket, and two displacement plates are slidably connected to the surface of the slide bar, and clamping plates are fixedly installed on the sides of the displacement plates. The setting of the clamping plates serves the purpose of clamping and limiting the position of the fixture cover.

[0007] Preferably, an electric telescopic rod is fixedly mounted on the top inner wall surface of the U-shaped bracket, a T-shaped plate is fixedly mounted on the output end of the electric telescopic rod, and two hinged plates are hingedly connected to the bottom surface of the T-shaped plate, and the ends of the hinged plates away from the T-shaped plate are hingedly connected to the displacement plate. The electric telescopic rod has the effect of driving the movement of the T-shaped plate.

[0008] Preferably, a limiting device is provided on the surface of the support frame, the limiting device comprising a slide groove provided on the surface of the support frame, a slide plate slidably connected thereto, a limiting rod fixedly mounted on the surface of the slide plate, and a limiting hole provided on the side of the mounting plate. The limiting rod and the limiting hole serve to limit the mounting plate within the mounting groove.

[0009] Preferably, an operating rod is fixedly mounted on the end surface of the slide away from the chute, and the operating rod is a "U"-shaped structure. The setting of the operating rod plays an effect of driving the slide to move inside the chute.

[0010] Preferably, a spring is fixedly mounted on the surface of one end of the slide away from the limiting rod, and the end of the spring away from the slide is fixedly connected to the inner wall of one side of the chute. The setting of the spring has the effect of limiting the position of the slide in the chute.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, by setting an auxiliary device, when the device needs to be used, first place the IGBT module detection part inside the placement seat, then place the fixture cover between the two clamping plates, and then start the electric telescopic rod. The electric telescopic rod starts to drive the T-plate to move, and the movement of the T-plate drives the hinged plate to move. The movement of the hinged plate pulls the two displacement plates to move in the direction of approaching each other on the surface of the slide rod. The two displacement plates move in the direction of approaching each other on the surface of the slide rod, driving the two clamping plates to move in the direction of approaching each other. The two clamping plates move in the direction of approaching each other to clamp the fixture cover to a limit position. When After the jig cover is limited and fixed, the cylinder is started, and the cylinder drives the U-shaped bracket to move, and the movement of the U-shaped bracket drives the jig cover to move, and the jig cover moves so that it covers the surface of the placement seat, thereby realizing the automation of clamping the IGBT module detection part by the placement seat and the jig cover. Finally, the IGBT module detection part is scanned and inspected using ultrasonic testing equipment. Through the cooperation of the above structure, the automation of clamping the part to be inspected by the placement seat and the jig cover is realized, and the ultrasonic scanning automatic jig can realize automated batch operation, thereby improving the inspection efficiency of the parts to be inspected.

[0013] 2. In the utility model, by setting a limit device, when the placement seat needs to be disassembled, the operating rod is first pushed, and the movement of the operating rod drives the slide plate to move inside the slide groove. The movement of the slide plate inside the slide groove will squeeze the spring, causing the spring to be compressed. At the same time, the movement of the slide plate inside the slide groove also drives the limit rod to move, and the limit rod moves to move itself out of the limiting hole. The separation of the limit rod and the limiting hole causes the mounting plate to lose its limit inside the mounting groove. At this time, the mounting plate can be moved out from the inside of the mounting groove, completing the disassembly operation between the placement seat and the support frame. Through the cooperation of the above structure, the placement seat and the support frame can be disassembled, thereby facilitating the replacement of the placement seat by the staff, so that the device can be applicable to different types of IGBT module detection parts, further improving the applicability of the device.

[0023] The specific configuration and function of the auxiliary device 5 and the limiting device 6 will be described in detail below.

[0024] In this embodiment: an auxiliary device 5 is provided on one side surface of the support frame 1, and the auxiliary device 5 includes a U-shaped plate 51, which is fixedly installed on one side surface of the support frame 1, and a cylinder 52 is fixedly installed on the surface of the top horizontal end of the U-shaped plate 51, and a U-shaped bracket 53 is fixedly installed on the output end of the cylinder 52.

[0025] In this embodiment, the cylinder 52 is provided to drive the U-shaped bracket 53 to move.

[0026] Specifically, a slide bar 54 is fixedly installed between the inner walls of both sides of the U-shaped bracket 53 , and two displacement plates 55 are slidably connected to the surface of the slide bar 54 . A clamping plate 56 is fixedly installed on the side of the displacement plate 55 .

[0027] In this embodiment, the provision of the clamping plate 56 serves the purpose of clamping and limiting the position of the fixture cover.

[0028] Specifically, an electric telescopic rod 59 is fixedly mounted on the top inner wall of the U-shaped bracket 53. A T-shaped plate 58 is fixedly mounted on the output end of the electric telescopic rod 59. Two hinged plates 57 are hingedly connected to the bottom surface of the T-shaped plate 58. The ends of the hinged plates 57 away from the T-shaped plate 58 are hingedly connected to the displacement plate 55. The electric telescopic rod 59 drives the T-shaped plate 58 to move.

[0029] In this embodiment: a limiting device 6 is provided on the surface of the support frame 1, and the limiting device 6 includes a slide groove 61, which is opened on the surface of the support frame 1, and a slide plate 62 is slidably connected inside the slide groove 61. A limiting rod 63 is fixedly installed on the surface of the slide plate 62, and a limiting hole 64 is opened on the side of the mounting plate 3. When it is necessary to disassemble the placement seat 4, first push the operating rod 65. The movement of the operating rod 65 drives the slide plate 62 to move inside the slide groove 61. The movement of the slide plate 62 inside the slide groove 61 will squeeze the spring 66, causing the spring 66 to be compressed. At the same time, the movement of the slide plate 62 inside the slide groove 61 also drives the limit rod 63 to move. The limit rod 63 moves to move itself out of the inside of the limit hole 64. The limit rod 63 and the limit hole 64 are separated, causing the mounting plate 3 to lose its limit inside the mounting groove 2. At this time, the mounting plate 3 can be removed from the inside of the mounting groove 2, completing the disassembly operation between the placement seat 4 and the support frame 1. Through the cooperation of the above structure, the placement seat 4 and the support frame 1 can be disassembled, thereby facilitating the replacement of the placement seat 4 by the staff, so that the device can be suitable for different types of IGBT module detection parts, further improving the applicability of the device.

[0030] Specifically, an operating rod 65 is fixedly mounted on the surface of one end of the slide plate 62 away from the slide groove 61 , and the operating rod 65 is a “U”-shaped structure.

[0031] In this embodiment, the operation lever 65 is provided to drive the slide plate 62 to move inside the slide groove 61 .

[0032] Specifically, a spring 66 is fixedly mounted on the surface of one end of the slide plate 62 away from the limiting rod 63 , and the end of the spring 66 away from the slide plate 62 is fixedly connected to an inner wall of one side of the slide groove 61 .

[0033] In this embodiment, the provision of the spring 66 has the effect of limiting the position of the slide plate 62 inside the slide groove 61 .

[0034] Working principle: By setting the auxiliary device 5, when the device needs to be used, first place the IGBT module detection part inside the placement seat 4, then place the jig cover between the two clamping plates 56, and then start the electric telescopic rod 59. The electric telescopic rod 59 starts to drive the T-plate 58 to move, and the movement of the T-plate 58 drives the hinged plate 57 to move. The movement of the hinged plate 57 pulls the two displacement plates 55 to move closer to each other on the surface of the slide rod 54. The two displacement plates 55 move closer to each other on the surface of the slide rod 54, driving the two clamping plates 56 to move closer to each other. The two clamping plates 56 move closer to each other to move the jig cover. The plate is clamped and limited. When the jig cover is limited and fixed, the cylinder 52 is started. The cylinder 52 starts to drive the U-shaped bracket 53 to move. The U-shaped bracket 53 moves and drives the jig cover to move. The jig cover moves so that it covers the surface of the placement seat 4, thereby realizing the automation of clamping the IGBT module detection part by the placement seat 4 and the jig cover. Finally, the IGBT module detection part is scanned and detected using ultrasonic detection equipment. Through the cooperation of the above structure, the automation of clamping the part to be detected by the placement seat 4 and the jig cover is realized, and the ultrasonic scanning automatic jig can realize automated batch operation, thereby improving the detection efficiency of the parts to be detected. When it is necessary to disassemble the placement seat 4, first push the operating rod 65. The movement of the operating rod 65 drives the slide plate 62 to move inside the slide groove 61. The movement of the slide plate 62 inside the slide groove 61 will squeeze the spring 66, causing the spring 66 to be compressed. At the same time, the movement of the slide plate 62 inside the slide groove 61 also drives the limit rod 63 to move. The limit rod 63 moves to move itself out of the inside of the limit hole 64. The limit rod 63 and the limit hole 64 are separated, causing the mounting plate 3 to lose its limit inside the mounting groove 2. At this time, the mounting plate 3 can be removed from the inside of the mounting groove 2, completing the disassembly operation between the placement seat 4 and the support frame 1. Through the cooperation of the above structure, the placement seat 4 and the support frame 1 can be disassembled, thereby facilitating the replacement of the placement seat 4 by the staff, so that the device can be suitable for different types of IGBT module detection parts, further improving the applicability of the device.
