Description

Technical Field

[0001] This utility model relates to the technical field of silicon wafer string bonding, and in particular to a silicon wafer centering positioning structure. Background Technology

[0002] Photovoltaic silicon wafers are the core and most valuable component of a solar power generation system. Their function is to convert solar energy into electrical energy, which is then stored in batteries or used directly as a power source. Currently, BC cells (back-contact cells, which can be combined with various circuits) require the silicon wafers to be transported to a suitable location for string welding with adhesive strips and welding wires during production. During transportation, the silicon wafers may shift, affecting the subsequent thermal fusion bonding with the adhesive strips. Utility Model Content

[0003] One objective of this invention is to provide a silicon wafer centering positioning structure that, under the movement of the approaching synchronous belt, simultaneously affects the opening and closing of the rear approaching arm and the side approaching arm, thereby centering the silicon wafer on the track.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A silicon wafer centering positioning structure includes a convergence base, a rear convergence arm, and two side convergence arms. A convergence drive wheel and a convergence driven wheel are mounted on the convergence base. A convergence timing belt drives the convergence drive wheel and the convergence driven wheel. The lower end of the rear convergence arm is fixed to one side of the convergence timing belt. The rear convergence arm moves in the front-back direction. A convergence fixing plate is connected to the other side of the convergence timing belt. An inclined convergence guide groove is provided on the convergence fixing plate. A convergence guide wheel is mounted on each side convergence arm and is positioned within the convergence guide groove. The side convergence arm moves in the left-right direction.

[0006] As a preferred technical solution, a convergence motor is installed at the lower end of the convergence base, and the drive end of the convergence motor is connected to the middle part of the convergence drive wheel.

[0007] As a preferred technical solution, the center of the approaching base is fixed with an approaching front and rear slide rail along the front and rear direction, the lower end of the rear approaching arm slides on the approaching front and rear slide rail, an approaching connecting seat slides on the approaching front and rear slide rail, and the approaching fixing plate is locked on the approaching connecting seat.

[0008] As a preferred technical solution, both sides of the front and rear sliding rails are equipped with left and right sliding rails, the left and right sliding rails are fixed on the bottom platform, and the side closing arms slide on the left and right sliding rails.

[0009] As a preferred technical solution, both the upper end of the rear abutment arm and the upper end of the side abutment arm are provided with abutment push rods. The abutment push rods are provided with abutment adjustment grooves, and the abutment push rods are locked to the side abutment arms by screws in the position of the abutment adjustment grooves.

[0010] The beneficial effects of this utility model are as follows: It provides a silicon wafer centering positioning structure, which is used to center and position the silicon wafer after flipping and turning. With the drive of a single motor, the three-way approaching arms are simultaneously controlled to approach the center of the track to straighten and position the silicon wafer, which is convenient for taking pictures and inspection, and prepares for subsequent application of adhesive strips.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 2 As shown in this embodiment, a silicon wafer centering positioning structure includes a convergence base 1, a rear convergence arm 2, and two side convergence arms 3. A convergence drive wheel 4 and a convergence driven wheel 5 are installed on the convergence base 1. A convergence synchronous belt 6 is connected between the convergence drive wheel 4 and the convergence driven wheel 5. The lower end of the rear convergence arm 2 is fixed to one side of the convergence synchronous belt 6. The rear convergence arm 2 moves along the front-back direction. A convergence fixing plate 7 is connected to the other side of the convergence synchronous belt 6. An inclined convergence guide groove 8 is provided on the convergence fixing plate 7. A convergence guide wheel 9 is installed on the side convergence arm 3. The convergence guide wheel 9 is located in the convergence guide groove 8. The side convergence arm 3 moves along the left-right direction.

[0018] The silicon wafers delivered from the front end have already undergone flipping and turning. Their position on the current track cannot be guaranteed to be in the middle, which is not conducive to gripping them to the position for applying adhesive strips. When the approach drive wheel 4 rotates, the auxiliary approach driven wheel 5 causes the approach timing belt 6 to move. This controls the approach fixing plate 7 and the rear approach arm 2 to move in opposite directions. At the same time, when the approach fixing plate 7 moves backward, the approach guide wheel 9 in the approach guide groove 8 moves, and the side approach arm 3 moves inward, so that the rear approach arm 2 and the side approach arm 3 can synchronously position the silicon wafer in the middle.

[0019] A proximity motor 10 is installed at the lower end of the proximity base 1. The drive end of the proximity motor 10 is connected to the middle of the proximity drive wheel 4. The drive structure is the proximity motor 10. After the proximity motor 10 is started, it drives the proximity drive wheel 4 to rotate, thereby causing the proximity timing belt 6 to pull the rear proximity arm 2 and the side proximity arm 3 to move closer together in the center.

[0020] A front-to-back sliding rail 11 is fixed in the middle of the base platform 1 along the front-to-back direction. The lower end of the rear-end closing arm 2 slides on the front-to-back sliding rail 11. A closing connecting seat 12 also slides on the front-to-back sliding rail 11. The closing fixing plate 7 is locked on the closing connecting seat 12. A left-to-right closing sliding rail 13 is installed on both sides of the front-to-back sliding rail 11. The left-to-right closing sliding rail 13 is fixed on the base platform 1. The side closing arm 3 slides on the left-to-right closing sliding rail 13. During the movement of the closing synchronous belt 6, the two belts move forward and backward. The side moving forward pulls the rear-end closing arm 2 forward along the front-to-back sliding rail 11. At the same time, the side moving backward pulls the closing connecting seat 12 backward, that is, the closing fixing plate 7 moves backward. Under the drive of the closing guide groove 8, the side closing arm 3 is forced to move towards the middle along the left-to-right closing sliding rail 13.

[0021] Both the upper end of the rear-end converging arm 2 and the upper end of the side converging arm 3 are provided with converging push rods 14. The converging push rods 14 are provided with converging adjustment grooves 15. The position of the converging push rods 14 in the converging adjustment grooves 15 is locked to the side converging arm 3 by screws. When the rear-end converging arm 2 and the side converging arm 3 move towards the middle, the converging push rods 14 are pushed from the three sides of the silicon wafer to center it. The position of the converging push rods 14 can be adjusted in the converging adjustment grooves 15 according to the different sizes of silicon wafers.

[0022] 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.
