[0001] This utility model relates to the field of chip processing technology, specifically a measuring arm with a calibration structure. Background Technology

[0002] A chip, also known as an integrated circuit, integrates hundreds or thousands of transistors into a tiny electronic device, combining functions such as storage, control, information processing, and information transmission. The basic component of a chip is a silicon disk called a wafer, on which various circuits, transistors, and input / output ports are integrated.

[0003] To accurately inject adhesive and assemble chips, mechanical devices such as measuring arms are needed during the adhesive injection process to help calibrate the transported chips and prevent misalignment of the dispensing position from affecting the assembly. However, the measuring positions of such machines are mostly fixed, making it difficult to accurately fit the conveyor for position locking, which is quite inconvenient to use.

[0004] Now, a novel measuring arm with a calibration structure is proposed to solve the above problems. Utility Model Content

[0007] As a further technical solution of this utility model, the right side of the output end of the motor is fixedly connected to the screw, and the threaded block guides the transverse track to move left and right.

[0008] As a further technical solution of this utility model, the outer wall of the screw matches the inner wall texture of the threaded block, and the threaded block and the transverse track are on the same vertical plane.

[0009] As a further technical solution of this utility model, a motor three is installed at the rear of the outside of the transverse track, a movable chamber is provided between the front and rear of the center of the inside of the transverse track, and sliding grooves are respectively provided on both sides of the top of the movable chamber. A screw two is movably connected between the front and rear of the inside of the movable chamber, and a threaded sleeve is threadedly connected to the outside of the screw two. Support blocks are fixed on both sides of the top of the threaded sleeve, and the tops of the support blocks on both sides are fixedly connected to the slide plate. Ball bearings are movably embedded on both sides of the bottom of the threaded sleeve.

[0010] As a further technical solution of this utility model, the output end of the motor three is fixedly connected to the screw two, and the support block is symmetrically fixed to the lower left side of the slide plate.

[0011] As a further technical solution of this utility model, the bottom of the ball is in contact with the inner wall of the movable cavity, and the support block is embedded in the groove.

[0012] As a further technical solution of this utility model, a vertical groove is provided between the upper and lower parts of the center of the longitudinal track, and a limit groove is provided longitudinally at the front end of both sides of the vertical groove. A motor is installed above the outside of the longitudinal track. A screw is movably connected between the upper and lower parts of the vertical groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the measuring arm with calibration structure not only realizes the initial adjustment of the position of the detection mechanism and the secondary adjustment of the position of the detection mechanism, but also realizes synchronous and precise positioning; By connecting a threaded block to the external thread of screw one, a support frame is built near the conveyor. Motor one is started and screw one is rotated. The threaded block is moved left and right along the inner wall of the transverse groove, and the transverse track installed on the top of the threaded block is guided to approach the conveyor and the chip being conveyed on its surface. The sliding plate is moved back and forth by the transverse track, and the lifting block is moved up and down by the longitudinal track. This not only adjusts the position of the dispensing tube, but also works with the optical imaging module installed in the right fixed plate to capture the chip conveying situation in real time through the camera, avoiding glue splashing to other places. By fixing a transverse rail to the top of the threaded block, the motor is started after adjusting the position of the transverse rail left and right. The sliding plate with the threaded sleeve is pushed back and forth in the movable chamber inside the transverse rail. At this time, the support block at the bottom of the sliding plate also slides along the slide groove. The sliding plate can be moved back and forth and the stability of the object can be maintained. It also prevents jamming, changes the calibration position a second time, and assists the processing mechanism in injecting glue. By installing a lifting block on the external thread of screw three, motor two is started according to the height of the conveyor plate, and screw three is rotated in the vertical groove in the center of the longitudinal track. Under the locking restriction of the slider by the limit grooves on both sides, the lifting block and the material pump and glue injection pipe installed above and below can be moved vertically, forcing the glue injection structure to approach the chip and then inject glue again. The optical imaging module installed on the right fixed plate is monitored with camera assistance to achieve the purpose of calibration measurement. Attached Figure Description
