[0002] An integrated chip is a precision semiconductor structure. One of the production processes involves turning the orientation of all integrated chips on the production line to facilitate the glazing operation in subsequent processes. Currently, enterprises mainly use manual turning methods to adjust the orientation of integrated chips on the production line, which greatly consumes labor costs. In addition, as a precision semiconductor structure, integrated chips are difficult to achieve standardized operation in manual work, which may damage the integrated chip structure and affect the subsequent processing quality of integrated chips. Summary of the Invention

[0003] To solve the problems of high manual labor intensity and unstable operation in the current orientation adjustment operation of the integrated chip production line, the purpose of the utility model is to provide an automatic chip turning device for an integrated chip production line. The normal - moving integrated chips are slightly pressed down by a smooth pressing plate until they enter a rubber sleeve. The rubber sleeve and the brush will perform a turning operation on the integrally - inverted chips, so that the orientations of all integrated chips in the production line are kept positive, facilitating the processing operations in subsequent processes of the integrated chips and improving the working efficiency of the production line.

[0004] To achieve the above - mentioned goal, the utility model adopts the following technical solutions: An automatic chip turning device for an integrated chip production line includes a support frame 5, a driving motor 6, a rubber sleeve 7, a smooth pressing plate 8, a brush support 9, a fixed footrest 10, a motor output shaft 11, a brush 12, and a support plate 13.

The smooth pressing plate 8 is integrally cast with the support frame 5. The rubber sleeve 7 and the motor output shaft 11 are in an interference - fit connection. The distance between the bottom of the brush 12 and the conveyor belt 3 is the height of the integrated chip.

[0005] The driving motor 6 is driven by a stepping motor, with a torque of 0.42 - 0.75 N, an input voltage of 24 - 80 VAC, a communication rate of 50 - 70 Kbps, and a pulse frequency of 200 - 300 K.

[0006] The Shore hardness of the rubber sleeve 7 is 20 - 40, and the elastic modulus is 10 - 100 MPa.

[0007] The smoothing pressing plate 8 is a metal mechanism, and the right side is a buffer tangent circle structure. The surface roughness Rz is 1 μm to 10 μm, and Ra is 0.25 μm to 2.5 μm.

[0008] The brush 12 is made of synthetic fiber, and the filament diameter of the bristles is 0.1 mm to 0.3 mm.

[0009] The surface roughness Rz of the conveyor belt is 50 to 200 μm, and Ra is 12.5 to 50 μm.

Detailed Embodiment

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. The specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] As shown Figure 1 in the figure, an automatic chip turning device for an integrated chip production line includes a support frame 5, a driving motor 6, a rubber sleeve 7, a smooth pressing plate 8, a brush support 9, a fixed leg 10, a motor output shaft 11, a brush 12, and a support plate 13. The support frame 5 and the support plate 13 are of an integral casting structure. The driving motor 6 and the support plate 13 are fixedly connected by screwing through the fixed leg 10. The brush support 9 and the support frame 5 are of an integral casting structure. The brush 12 is fixed in the brush support 9 by pressing in with a copper sheet. The smooth pressing plate 8 is integrally cast with the support frame 5. The rubber sleeve 7 and the motor output shaft 11 are connected by interference fit. The distance between the bottom of the brush 12 and the conveyor belt 3 is the height of the integrated chip.

[0021] The driving motor 6 is driven by a stepping motor, with a torque of 0.42 - 0.75 N, an input voltage of 24 - 80 VAC, a communication rate of 50 - 70 Kbps, and a pulse frequency of 200 - 300 K.

[0022] The Shore hardness of the rubber sleeve 7 is 20 - 40, and the elastic modulus is 10 - 100 MPa.

[0023] The smooth pressing plate 8 is a metal structure, with a buffer tangent circle structure on the right side. The surface roughness Rz is 1 μm - 10 μm, and Ra is 0.25 μm - 2.5 μm.

[0024] The brush 12 is made of synthetic fiber material, and the filament diameter of the bristles is 0.1 mm - 0.3 mm.

[0025] The surface roughness Rz of the conveyor belt is 50 - 200 μm, and Ra is 12.5 - 50 μm.

[0026] The smooth pressing plate 8 slightly presses down the normally moving integrated chip until the integrated chip enters below the rubber sleeve 7. The rubber sleeve 7 and the brush 12 will perform a turning operation on the integrally reversed chip.

[0027] The state of the integrated chip entering the production line in the forward direction is as shown Figure 2As shown in the figure, the conveyor belt 3 conveys the integrally-entering integrated chip 1 to the edge of the smooth pressing plate 8 under the drive of the pulley 4. The right side of the smooth pressing plate 8 is a buffer tangent circle structure, which can smoothly convey the integrated chip under the smooth pressing plate 8. The smooth pressing plate 8 slightly presses down the integrally-entering integrated chip 1 that is moving forward normally. Since the surface roughness of the smooth pressing plate 8 is very small, the surface is very smooth and only slightly presses down the integrated chip, so it will not affect the normal movement of the integrated chip. Also, since the plane of the integrally-entering integrated chip 1 contacts the conveyor belt 3, when the integrally-entering integrated chip 1 enters under the rubber sleeve 7, the integrally-entering integrated chip 1 will not warp and the height of the chip will not change. When the integrally-entering integrated chip 1 travels under the brush 12, since the distance between the bottom of the brush 12 and the conveyor belt 3 is exactly the height of the chip, the integrally-entering integrated chip 1 will not contact the brush 12 and the orientation will not change.

[0028] The state of the integrated chip entering the production line in the reverse direction is as Figure 3 shown. The conveyor belt 3 conveys the integrally-entering integrated chip 2 to under the smooth pressing plate 8 under the drive of the pulley 4 and presses it into the rubber sleeve 7. Since the plane of the integrally-entering integrated chip 2 faces upward and the cylindrical surface contacts the conveyor belt, the integrally-entering integrated chip 2 will warp when it is under the rubber sleeve 7 and the height of the chip increases. When the integrally-entering integrated chip 2 travels under the brush 12, the height of the chip is greater than the distance between the bottom of the brush 12 and the conveyor belt 3. At this time, the brush 12 will contact the integrally-entering integrated chip 2, and as the integrally-entering integrated chip 2 travels, the orientation will also be flipped to achieve the purpose of righting the integrally-entering integrated chip 2.

[0029] The working principle of the present utility model is as follows:

[0030] The conveyor belt 3 conveys the integrated chip to the edge of the smooth pressing plate 8 under the drive of the pulley 4. The right side of the smooth pressing plate 8 is a buffer tangent circle structure, which can smoothly convey the integrated chip under the smooth pressing plate 8. The smooth pressing plate 8 slightly presses down the normally-traveling integrated chip and maintains the normal movement of the integrated chip. When the integrated chip travels to the rubber sleeve 7, since the states of the integrally-entering integrated chip 1 and the integrally-entering integrated chip 2 when entering under the rubber sleeve 7 are different, the automatic righting device will only adjust the orientation of the integrally-entering integrated chip 2 in the reverse direction. When the integrated chip passes through the brush, the orientations have all been adjusted correctly.
