DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A chip repair observation device is shown.

[0024] The first embodiment of the utility model refers to Figure 1 A chip repair observation device includes an observation platform 1, the observation platform 1 is used to place the chip, an observation hole 101 is opened in the middle of the observation platform 1, and a plurality of springs 2 for fixing the chip are arranged on the upper part of the observation platform 1 through the rotation of a rotating rod, and the springs 2 are bent upward at one end away from the rotating rod. The springs 2 are lifted upward at one end away from the rotating rod, and the chip can be fixed on the observation platform 1 through the mutual compression of the springs 2 and the observation platform 1. When the observation platform 1 is turned over, the back of the chip can be observed through the observation hole 101. As a preferred embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a flipping device for vertically flipping the observation platform 1 and a rotating device for horizontally rotating the observation platform 1 are provided at the lower part of the observation platform 1. The flipping device can adjust and flip the vertical angle of the observation platform 1, and the rotating device can rotate the observation platform 1 to facilitate the adjustment of the position of the chip relative to the observer, thereby facilitating the observation of different positions of the chip. The flipping device includes a disc 3 and a support plate 7. A fixing seat 4 is symmetrically provided at the lower part of the disc 3. The lower ends of the fixing seats 4 are rotatably connected to the rotating holes opened at the top of the support plate 7 through circular sleeves 5. The base plate 6 also includes a metal plate-like structure. The support plates 7 are respectively arranged at the left and right ends of the upper surface of the base plate 6. The base plate 6 is convenient for placing the device in the use position. The rotating device includes a first bevel gear 8 and a transmission shaft 9. The first bevel gear 8 is arranged at the lower part of the observation platform 1. The transmission shaft 9 The shaft 9 is rotatably arranged inside the circular sleeve 5 on the right side, and the second bevel gear 10 arranged at the left end of the transmission shaft 9 is meshed and connected with the first bevel gear 8. A clutch assembly is arranged between the rotating hole opened at the top of the support plate 7 and the circular sleeve 5. The clutch assembly is used to increase the friction between the rotating hole opened at the top of the support plate 7 and the circular sleeve 5 to ensure that when the transmission shaft 9 is rotated alone, the circular sleeve 5 will not rotate therewith. The clutch assembly includes a clutch ball 11 and a spring 12. The springs 12 are respectively arranged in the mounting grooves opened on the inner wall of the rotating hole. The clutch balls 11 are respectively arranged at the outer ends of the springs 12. The clutch balls 11 correspond to the positions of the clutch grooves opened on the outer arc surface of the circular sleeve 5 respectively. The depth of the clutch groove is less than the ball radius of the clutch ball 11. It also includes a first hand wheel 13 and a second hand wheel 14. The first hand wheel 13 is arranged at the outer end of the circular sleeve 5 on the left side, and the second hand wheel 14 is arranged at the outer end of the transmission shaft 9.

[0025] When observing the chip, since the chip is a precision electronic component with a relatively small internal structure, it is usually necessary to use a magnifying device for auxiliary observation. At the same time, the chip needs to be adjusted in position during the observation process to facilitate observation of different positions of the chip. The chip is fixed on the observation platform 1 by the spring 2, and the first hand wheel 13 is rotated by the left hand. The first hand wheel 13 drives the fixing seat 4 and the upper component to rotate in the vertical direction through the circular sleeve 5, so as to adjust the vertical angle of the chip. In this process, since the depth of the clutch groove is less than the ball radius of the clutch ball 11, the circular sleeve 5 is rotated by force, so that the clutch ball 11 is disengaged from the clutch groove, and the spring 12 is compressed, so that the circular sleeve 5 can rotate with the upper component. The second hand wheel 14 is rotated by the right hand, and the second hand wheel 14 drives the transmission shaft 9 to rotate. At this time, since the clutch ball 11 is engaged with the clutch groove, the circular sleeve 5 will not rotate with the rotation of the transmission shaft 9. The transmission shaft 9 drives the observation platform 1 to rotate through the second bevel gear 10 and the first bevel gear 8, so as to adjust the horizontal rotation of the chip, thereby facilitating observation of different positions of the chip.

[0026] The second embodiment of the utility model refers to Figure 1As shown, a sliding device is provided at the bottom of the base plate 6. Preferably, the sliding device includes a base plate 15, a wire gauge 16 is provided on the upper part of the base plate 15, a slider 17 is slidably provided on the upper part of the wire gauge 16, and the base plate 6 is fixed to the upper part of the slider 17 by bolts.

[0027] When observing the chip, the observation device is placed under the lens of the magnifying device through the base plate 15, and the support plate 7 is pulled to make the slider 17 slide left and right along the wire gauge 16 with the substrate 6 and the upper components to adjust the relative position of the chip and the lens, so as to facilitate the observation of different positions of the chip after magnification and improve the observation efficiency of the chip.
