[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown in this embodiment, a silicon wafer flipping and turning mechanism for a BC battery string bonding machine includes a flipping bracket 1, a translational snap-fit ​​bracket 2, a half-wafer turning X-axis module 3, a half-wafer turning Z-axis module 4, and a half-wafer approach bracket 5. A flipping shaft 6 is rotatably connected to the flipping bracket 1, and a flipping frame 7 is fixed on the flipping shaft 6. Translational strips 8 are provided on both sides of the translational snap-fit ​​bracket 2, and translational belts 9 are movably mounted on the translational strips 8. Translational belts 9 are provided with translational adsorption holes. The 8 is provided with translational flapping arms 10 on both sides, and translational flapping wheels 11 are installed on the translational flapping arms 10. The half-piece steering Z-axis module 4 is installed on the drive end of the half-piece steering X-axis module 3. There are two steering cylinders 12 on the drive end of the half-piece steering Z-axis module 4 that move along the Y-axis direction. The drive end of the steering cylinders 12 is connected to a steering suction cup. The end of the half-piece approach bracket 5 is provided with an approach base 13. Approaching arms 14 are provided on both sides and the rear side of the approach base 13.

[0026] After the dried half-wafers enter the flipping bracket 1, the flipping shaft 6 rotates to flip the half-wafers on the flipping frame 7 and send them into the translational clamping bracket 2. Under the action of the translational adsorption holes of the translational belt 9, the half-wafers are clamped and then moved along the line of the translational strip 8 to the translational clamping arms 10, where the half-wafers are released. The translational clamping arms 10 position the half-wafers towards the center and then move them to the rear. The half-wafer turning X-axis module 3 controls the half-wafer turning Z-axis module 4 to move above the half-wafers. The half-wafer turning Z-axis module 4 controls the two turning cylinders 12 to move down and adsorb the half-wafers through the turning suction cups. After the turning cylinders 12 separate along the Y-axis, the double half-wafers can be turned simultaneously and then placed back on the half-wafer approach bracket 5. After the approaching arms 14 close, the position of the double half-wafers is fixed, which is convenient for docking with the rear mechanism.

[0027] A flipping motor 15 is provided on one side of the flipping bracket 1. The drive end of the flipping motor 15 is connected to one end of the flipping shaft 6. A flipping suction hole is installed on the flipping frame 7. The flipping motor 15 controls the rotation of the flipping shaft 6. The flipping frame 7 picks up the half silicon wafer through the flipping suction hole and then flips it.

[0028] A translation motor 16 is installed at the lower end of the translation and striking bracket 2. Translation synchronous pulleys 17 are installed at both the drive end of the translation motor 16 and the middle part of the translation and striking bracket 2. The translation synchronous pulleys 17 are connected by belt drive. Translation transmission pulleys 18 are connected to the shafts on both sides of the translation synchronous pulleys 17. The translation belt 9 is connected to the translation transmission pulleys 18. A translation air pipe connector 19 is installed on the outer side of the translation strip 8. The translation air pipe connector 19 is connected to the translation adsorption hole through the translation strip 8. A translation and striking motor 20 is installed at the upper end of the translation and striking bracket 2. The drive end of the translation and striking motor 20 is connected to the translation and striking synchronous pulley 21. The translation and striking synchronous pulley 21 is located on the outer side of the translation strip 8. The translation and striking synchronous pulleys 21 are connected by translation and striking synchronous belt drive. The translation and striking arm 10 is fixed on the translation and striking synchronous belt.

[0029] The translation motor 16 drives the translation belt 9 on the translation strip 8 through the mutual drive between the translation synchronous wheel 17 and the translation transmission wheel 18, which in turn drives the adsorbed half silicon wafer to move backward. The translation air pipe connector 19 controls the negative pressure of the translation adsorption hole to adsorb the half silicon wafer. The translation snapping motor 20, driven by the translation snapping synchronous wheel 21 and the translation snapping synchronous belt, controls the translation snapping arm 10 to move closer to the translation strip 8, stabilizing the position of the half silicon wafer in the middle.

[0030] A half-wafer steering frame 22 is mounted on the drive end of the half-wafer steering Z-axis module 4. A half-wafer pitch motor 23 and a half-wafer pitch synchronous pulley 24 are mounted on the half-wafer steering frame 22. The half-wafer pitch motor 23 is connected to the half-wafer pitch synchronous pulley 24. The half-wafer pitch synchronous pulleys 24 are connected by a half-wafer pitch synchronous belt 25. The steering cylinder 12 is fixed on the half-wafer pitch synchronous belt 25. The half-wafer steering Z-axis module 4 controls the half-wafer steering frame 22 to move down. After the two sets of steering suction cups pick up one half of the silicon wafer, the half-wafer pitch motor 23 pulls the two sets of steering cylinders 12 apart through the half-wafer pitch synchronous pulley 24 and the half-wafer pitch synchronous belt 25 to facilitate steering. After the steering cylinders 12 have steered the two half-wafers, they are brought back together. The half-wafer steering X-axis module 3 puts the steered half-wafers into the half-wafer bringing together bracket 5.

[0031] A half-piece approach bracket 5 is equipped with a half-piece approach track motor 26 at its lower end. The drive end of the half-piece approach track motor 26 is connected to a half-piece approach track synchronous pulley, and a half-piece approach track conveyor belt 27 is connected to the half-piece approach track synchronous pulley.

[0032] A half-piece positioning light source 28 and a half-piece signal sensor are installed on the half-piece approach bracket 5. A half-piece positioning camera 29 and a half-piece signal reflector 30 are set above the half-piece approach bracket 5.

[0033] The base platform 13 is provided with front and rear sliding rails, left and right sliding rails 31, and synchronous pulleys 32. A synchronous belt is connected to the synchronous pulleys 32. The synchronous belt is connected to the rear arm 14. The rear arm 14 slides on the front and rear sliding rails. A fixing plate 33 is fixed on the rear arm 14. A guide groove 34 is provided on the fixing plate 33. The two arms 14 slide on the left and right sliding rails 31. Guide wheels 35 are installed on the two arms 14. The guide wheels 35 move within the guide grooves 34.

[0034] The half-piece approaching track motor 26 moves the two halves backward through the half-piece approaching track synchronous wheel and the half-piece approaching track conveyor belt 27. After the half-piece signal sensor senses the movement, the half-piece positioning camera 29 performs defect detection on the two halves. Finally, when the approaching synchronous wheel 32 rotates, it drives the approaching synchronous belt to move, and the rear approaching arm 14 pulls back. At the same time, the approaching arms 14 on both sides are controlled to move towards the middle synchronously under the action of the approaching guide groove 34 and the approaching guide wheel 35, bringing the positions of the two halves together to prepare for the subsequent application of adhesive strips.

[0035] All modules involved in this application are linear modules.

[0036] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
