[0019] In order to make the objectives, technical solutions and advantages of the utility model clearer, the following further details the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0020] As Figures 1 to 8 shown, the utility model provides a chip mounter 100 with an automatic calibration function, which includes a processing table 10, a sliding frame 20, a fixing component 30, a mounting component 40 and an alignment component 50. A moving slide rail 11 is provided on the processing table 10. The sliding frame 20 stands on the processing table 10. The fixing component 30 is clamped and installed in the moving slide rail 11 and can slide left and right. The mounting component 40 is installed on the sliding frame 20. The alignment component 50 is installed on the mounting component 40. It can be understood that several driving devices, sensors and control systems are also included in the utility model. Since they are all conventional technical contents in this technical field, they will not be elaborated here.

[0021] The sliding frame 20 includes a vertical frame 21 and a horizontal frame 22. The vertical frame 21 stands on the processing table 10, and a longitudinal slide rail (not shown in the figure) is provided on the vertical frame 21. The horizontal frame 22 is clamped and installed on the longitudinal slide rail and can slide back and forth. And a horizontal slide rail (not shown in the figure) is provided on the horizontal frame 22. The telescopic robotic arm 41 is clamped and installed on the horizontal slide rail and can slide left and right. The sliding frame 20 provided with the longitudinal slide rail and the horizontal slide rail can drive the mounting component 40 to freely locate at any pad of the circuit board for chip mounting processing, greatly improving the applicable range of the chip mounter.

[0022] The fixing component 30 includes a lifting slide rod 31, a pressing plate 32 and a limiting block 33. The lifting slide rod 31 is engaged and installed on the moving slide rail 11 and can be adjusted and slid left and right. The pressing plate 32 is installed at the upper end of the lifting slide rod 31, and a limiting slide hole 321 is provided on the pressing plate 32. The limiting block 33 is engaged and installed in the limiting slide hole 321 and can be adjusted and slid back and forth. The lifting slide rod 31 can drive the pressing plate 32 to press and fix the surface of the circuit board, while the limiting block 33 can limit the side of the circuit board, so as to effectively prevent the circuit board from being displaced during the chip mounting process.

[0023] The chip mounting component 40 includes a telescopic robotic arm 41, a negative pressure suction cup 42 and a plurality of calibration sliders 43. The telescopic robotic arm 41 is installed on the sliding frame 20 and can move horizontally and vertically. The negative pressure suction cup 42 is installed at the lower end of the telescopic robotic arm 41. A plurality of negative pressure suction holes 421 and calibration chutes 422 are provided at the bottom of the negative pressure suction cup 42. A plurality of the calibration sliders 43 are respectively engaged and installed in a plurality of the calibration chutes 422 and can be adjusted and slid. When the negative pressure suction cup 42 grabs a component, the component adsorbed on the bottom of the negative pressure suction cup 42 is very likely to be in a skewed position. At this time, a plurality of calibration sliders 43 will slide from the four sides to the center at the same time. During the sliding process, the calibration sliders 43 will push the component, so that it can be completely calibrated from the skewed state.

[0024] The alignment component 50 includes an installation ring 51 and a plurality of alignment laser sensors 52. The installation ring 51 is sleeved on the telescopic robotic arm 41, and a plurality of the alignment laser sensors 52 are all installed on the installation ring 51 from top to bottom. After the chip mounting component 40 grabs a component, the alignment laser sensors 52 will start to work and emit alignment laser downward. When the alignment laser corresponds to the alignment target on the circuit board up and down, the up and down alignment of the component and the chip mounting pad can be realized, and then the precise and efficient chip mounting processing can be realized.

[0025] The sliding frame 20 further includes a transverse strengthening rod 23. The transverse strengthening rod 23 is installed between the vertical frames 21, and an adjustment slide hole 231 is also provided on the transverse strengthening rod 23. The telescopic robotic arm 41 includes a telescopic sleeve 411, a telescopic rod core 412 and a plurality of auxiliary alignment magnetic strips 413. The telescopic sleeve 411 is designed with an opening downward. The telescopic rod core 412 passes through the telescopic sleeve 411 from bottom to top and can be lifted vertically. A plurality of the auxiliary alignment magnetic strips 413 are respectively engaged and installed on the four sides of the telescopic rod core 412.

[0026] The chip mounter 100 with an automatic correction function further includes an auxiliary alignment assembly 60. The auxiliary alignment assembly 60 includes a telescopic adjustment rod 61, an auxiliary alignment frame 62, a plurality of electromagnets 63, and alignment laser receivers 64. The telescopic adjustment rod 61 is snap-fitted in the adjustment slide hole 231 and can be adjusted and slid left and right. The telescopic adjustment rod 61 can also be telescoped back and forth. The auxiliary alignment frame 62 is clamped between the telescopic adjustment rods 61 and is located below the negative pressure suction cup 42. A plurality of the electromagnets 63 are installed on the inner side of the auxiliary alignment frame 62 and are arranged corresponding to a plurality of auxiliary alignment magnetic strips 413. A plurality of the alignment laser receivers 64 are installed on the upper end of the auxiliary alignment frame 62 and are vertically corresponding to a plurality of alignment laser sensors 52.

[0027] After the alignment assembly 50 completes the vertical alignment of the mounting assembly 40 and the circuit board pads, the telescopic rod core 412 in the telescopic robotic arm 41 will drive the negative pressure suction cup 42 and the grabbed component to descend vertically. During the descent, the telescopic rod core 412 will gradually pass through the auxiliary alignment frame 62. At this time, the auxiliary alignment magnetic strips 413 on the four sides of the telescopic rod core 412 correspond to the electromagnets 63 on the inner side of the auxiliary alignment frame 62, and the magnetic force generated between the two can keep the telescopic rod core 412 descending vertically without being deflected due to factors such as vibration.

[0028] In summary, the beneficial effects of the chip mounter 100 with an automatic correction function of the present utility model are as follows: By designing the negative pressure suction cup 42 with a correction slide hole, the negative pressure suction cup 42 can automatically correct the skew problem after grabbing the component, thereby realizing precise and efficient chip mounting processing; Designing the fixing assembly 30 to fix the circuit board can avoid the circuit board shifting during the chip mounting process and affecting the chip mounting processing; Designing the alignment assembly 50 to achieve high-precision alignment, and additionally designing the auxiliary alignment assembly 60 to further improve the accuracy of the vertical alignment between the component and the circuit board pad, making the quality of the chip mounting processing higher; The present utility model has strong practicability and has strong popularization significance.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
