Description

Technical Field

[0001] This utility model relates to the field of fixture testing technology, specifically a fixture high-temperature deformation testing device. Background Technology

[0002] A ball-mounting fixture is a specialized tool used in electronic assembly processes to mount BGA components. It is primarily used for mounting BGA components on printed circuit boards (PCBs), ensuring accurate placement and fixation of the components for subsequent soldering.

[0003] The application scenarios of ball-planting jigs often involve high-temperature environments. Therefore, high-temperature testing is required during jig processing. Typically, the jig plate is placed in a high-temperature heating chamber. After heating, the deformation of the jig compared to its normal temperature is measured. Currently, in the process of testing jigs, traditional detectors are fixed and cannot be adjusted in angle. Moreover, because jigs are not easy to rotate at high temperatures, the detectors can only measure a single angle and cannot measure multiple angles of the jig. Utility Model Content

A drive shaft 4 is fixedly installed on the output end of the drive motor 3. A rotating disk 5 is fixedly installed on the drive shaft 4. The rotating disk 5 is rotatably installed on the device base 1 and is used to place the fixture. An adjustment component is provided on the device base 1. A U-shaped support rod 6 is provided on the adjustment component. A mounting plate 7 is fixedly installed on the lower end face of the U-shaped support rod 6.

[0027] In this embodiment, the heated fixture is placed on the rotating disk 5. The forward and reverse rotation of the drive motor 3 drives the rotating disk 5 on the drive shaft 4 to rotate. The rotating disk 5 drives the fixture to rotate at an angle. The detector 8 detects the fixture in the rotating state, which effectively improves the accuracy of the fixture detection.

[0028] The adjustment assembly includes a large sprocket 9 fixedly mounted on the drive shaft 4, a U-shaped frame plate 10 fixedly mounted on the rear side of the device base 1, an adjusting screw 11 rotatably mounted on the U-shaped frame plate 10, a small sprocket 12 fixedly mounted on the adjusting screw 11, the small sprocket 12 being positioned below the device base 1, the large sprocket 9 being driven by the small sprocket 12 via a chain, a lifting block 13 movably mounted on the adjusting screw 11, a limit slider 14 fixedly mounted on the side end face of the lifting block 13, a limit groove 15 formed on the inner side of the U-shaped frame plate 10, the limit slider 14 slidingly mounted with the limit groove 15, and a connecting cross plate 16 fixedly mounted on the lifting block 13. A bearing 17 is fixedly installed on the lower end face of plate 16, and a spiral rod 18 is fixedly installed on the bearing 17. A U-shaped horizontal plate 19 is fixedly installed on the device base 1. A spiral hole 20 is opened on the U-shaped horizontal plate 19 to cooperate with the spiral rod 18. The spiral rod 18 and the spiral hole 20 are in the same vertical direction. The end of the spiral rod 18 away from the bearing 17 passes through the spiral hole 20 and is fixedly installed with the U-shaped frame rod 6. The spiral rod 18 and the spiral hole 20 are movably installed. The shape and principle of the spiral rod 18 and the spiral hole 20 are technologies well known to those skilled in the art and will not be described in detail here. The position of the U-shaped horizontal plate 19 is directly below the spiral hole 20.

[0029] In this embodiment, when the drive shaft 4 rotates in both directions, it drives the large sprocket 9 to rotate. When the large sprocket 9 rotates, it drives the small sprocket 12 to rotate via a chain. When the small sprocket 12 rotates, it drives the adjusting screw 11 to rotate. The lifting block 13 on the adjusting screw 11 is limited by the limiting slider 14 and the limiting groove 15, thereby adjusting the position of the detector 8 on the connecting horizontal plate 16 to ensure that the detector 8 can perform uniform detection on the fixture.

The detector 8 with adjustable angle is used to further improve the detection effect of the fixture.

[0030] Working principle: In use, the heated fixture is placed on the rotating disk 5. The forward and reverse rotation of the drive motor 3 drives the rotating disk 5 on the drive shaft 4 to rotate. The rotating disk 5 drives the fixture to rotate at an angle. The detector 8 detects the fixture in the rotating state. When the drive shaft 4 rotates forward and reverse, it drives the large sprocket 9 to rotate. When the large sprocket 9 rotates, it drives the small sprocket 12 to rotate through the chain. When the small sprocket 12 rotates, it drives the adjusting screw 11 to rotate. The lifting block 13 on the adjusting screw 11 is limited by the limiting slider 14 and the limiting groove 15, thereby adjusting the position of the detector 8 on the connecting horizontal plate 16 to ensure that the detector 8 can perform uniform detection of the fixture. When the connecting horizontal plate 16 is raised and lowered, the spiral rod 18 on the connecting horizontal plate 16 is limited by the bearing 17 and works with the spiral hole 20 on the U-shaped horizontal plate 19 to ensure that the detector 8 on the U-shaped frame rod 6 is in a rotating state. The angle-adjustable detector 8 improves the detection effect of the fixture.
