Description

Technical Field

[0001] This application relates to the technical field of silicon wafer packaging, and in particular to an automated material sorting device based on packaging equipment. Background Technology

[0002] Packaging is a crucial step in silicon wafer production and plays a vital role in the process. With the development of the photovoltaic industry, in order to effectively control costs and obtain greater benefits, the thickness of photovoltaic silicon wafers is becoming smaller and the area is becoming larger.

[0003] During the packaging process, silicon wafers need to be stacked and placed in packaging bags for boxing. However, because silicon wafers are thin and have sharp edges, if the stacked silicon wafers are not neat enough, the edges of the stack will form several sharp corners that can easily damage the packaging bags and affect subsequent boxing. Utility Model Content

[0004] To protect packaging bags and facilitate subsequent boxing, this application provides an automated material sorting device based on packaging equipment.

[0005] The automated material sorting device based on packaging equipment provided in this application adopts the following technical solution: An automated material straightening device based on a packaging equipment includes a conveyor belt comprising two parallel belt bodies with a gap between them. A straightening seat is vertically slidably connected to the conveyor belt, and two straightening blocks (first type) are horizontally linearly slidably connected to the straightening seat, facing each other. The first straightening blocks are directly opposite the gap. Two straightening blocks (second type) are horizontally linearly slidably connected to the straightening seat, facing each other. The two second straightening blocks are located on opposite sides of the conveyor belt, and the sliding direction of the second straightening blocks is perpendicular to the sliding direction of the first straightening blocks.

[0006] By adopting the above technical solution, the silicon wafer stack is conveyed on the conveyor belt. When the silicon wafer stack is conveyed to the top of the straightening seat, the straightening seat rises until straightening block one and straightening block two are located around the silicon wafer stack. The two straightening blocks one and two straightening blocks two move towards each other, and straightening blocks one and two straightening blocks two push the silicon wafer stack around its perimeter, thereby straightening the silicon wafer stack and facilitating subsequent bagging and boxing.

[0007] Preferably, one of the regularized blocks, the two facing each other, has a buffer block connected to it by a spring.

[0008] By adopting the above technical solution, the buffer block uses springs to buffer and protect the silicon wafer stack, preventing excessive pressure from the first and second regularization blocks from damaging the silicon wafer stack.

[0009] Preferably, the aligning base includes a base, on which a lifting cylinder is provided, the output shaft of which is connected to a lifting plate, and the first aligning block and the second aligning block are installed on the upper surface of the lifting plate. A buffer is vertically provided on the base.

[0010] By adopting the above technical solution, the lifting plate moves up and down under the action of the lifting cylinder, thereby driving the straightening block one and straightening block two to move up and down to sort the silicon wafer stack. When the lifting plate descends, the buffer protects the lifting plate and prevents the lifting plate from descending too much and colliding with the base.

[0011] Preferably, the lifting plate is vertically provided with a support plate directly opposite the gap, the first and second regularizing blocks are located around the support plate, and a sensor for detecting the silicon wafer stack is provided at the center of the support plate.

[0012] By adopting the above technical solution, the sensor is used to detect the position of the silicon wafer stack. When the sensor detects the silicon wafer stack, the conveyor belt stops conveying, the lifting plate is lifted, and the support plate passes through the gap and rises to provide resistance and support to the silicon wafer stack. The sizing block one and the sizing block two cooperate with each other to size the silicon wafer stack.

[0013] Preferably, the conveyor belt is provided with a detection seat, and the alignment seat and the detection seat are arranged sequentially along the conveying direction of the conveyor belt. The detection seat is provided with four sets of camera groups located above the conveyor belt. Each set of camera groups includes two side cameras arranged side by side. The four sets of camera groups are located at the four sides of the silicon wafer stack.

[0014] By adopting the above technical solution, the silicon wafer stack after being aligned continues to be transported forward by the conveyor belt until it reaches the detection seat. The four sets of cameras at the detection seat scan the four sides of the silicon wafer stack to detect whether the silicon wafer stack is aligned in place.

[0015] Preferably, the detection base is provided with angled cameras located below the camera group. The angled cameras are provided in four groups located at the four corners of the silicon wafer stack. Each group contains two angled cameras facing each other, and the two angled cameras in each group are respectively tilted and located on both sides of the corner of the silicon wafer stack.

[0016] By adopting the above technical solution, the angled camera captures images of the four corners of the silicon wafer stack, working in conjunction with the camera group to capture and detect the edges and corners of the silicon wafer stack, thereby improving detection accuracy.

[0017] Preferably, the detection seat is vertically slidably connected to a lifting seat that is directly opposite the gap.

[0018] By adopting the above technical solution, when the silicon wafer stack moves to the top of the lifting platform, the conveyor belt stops conveying, the lifting platform rises to lift the silicon wafer stack, and raises the silicon wafer stack to the height of the camera group for shooting and detection. Moreover, the lifting platform can change the height of the silicon wafer stack, so that the camera group can perform a complete inspection of the silicon wafer stack from top to bottom, thereby improving the inspection effect.

[0019] Preferably, a placement rack is provided next to the conveyor belt, a paper material frame is provided on the placement rack, sulfuric acid paper is placed in the paper material frame, and a suction cup for transporting sulfuric acid paper is movably connected to the placement rack.

[0020] By adopting the above technical solution, the suction cup picks up the sulfuric acid paper from the paper box and lays it on the conveyor belt. The silicon wafers are stacked on the sulfuric acid paper for transportation, and the sulfuric acid paper protects the silicon wafer stack.

[0021] Preferably, the paper frame is horizontally slidably connected to the placement frame, and the sliding direction of the paper frame is perpendicular to the conveying direction of the conveyor belt. A paper pusher is vertically slidably connected inside the paper frame, and the paper pusher is connected to the paper frame by a vertically arranged paper pusher rod.

[0022] By adopting the above technical solution, the paper stock is in working condition when it is near the end of the conveyor belt, where the suction cup can pick up the tracing paper inside the paper stock. When the paper stock moves to the end away from the conveyor belt, it is in paper-adding condition, where the operator adds tracing paper to the paper stock. As the suction cup gradually picks up the tracing paper, the amount of tracing paper gradually decreases. At this time, the paper pusher gradually rises, raising the paper pusher seat, thereby ensuring that the height of the top tracing paper is always at a relatively consistent position to facilitate the suction cup's pickup.

[0023] In summary, this application includes at least one of the following beneficial technical effects: The two aligning blocks work together to push and align the silicon wafers around the perimeter of the stack, thereby improving the neatness of the stack and facilitating subsequent bagging and boxing. The testing station inspects the silicon wafer stacks to check the alignment effect after the silicon wafer stacks are aligned, so as to ensure that the silicon wafer stacks transported later meet the packing requirements.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] Example

[0028] This application discloses an automated material straightening device based on packaging equipment, referring to... Figure 1 The system includes a conveyor belt 1, a sizing station 2, a testing station 4, and a placement rack 5. The conveyor belt 1 comprises two parallel belt bodies 11 with a gap 12 between them. The conveyor belt 1 is used for linearly transporting silicon wafer stacks. The sizing station 2 and the testing station 4 are arranged sequentially along the conveying direction of the conveyor belt 1. The silicon wafer stacks are first sized by the sizing station 2 and then transported to the testing station 4 for testing. The placement rack 5 is located on one side of the input end of the conveyor belt 1 and is used to place tracing paper to protect the silicon wafer stacks onto the conveyor belt 1.

[0029] Reference Figure 1 A paper tray 51 is horizontally slidably connected to the placement rack 5, and the sliding direction of the paper tray 51 is perpendicular to the conveying direction of the conveyor belt 1. When the paper tray 51 is located at one end of the placement rack 5 closer to the conveyor belt 1, the paper tray 51 is located at the working station; when the paper tray 51 is located at one end of the placement rack 5 away from the conveyor belt 1, the paper tray 51 is located at the paper feeding station. The paper tray 51 first moves to the paper feeding station where an operator or robot adds tracing paper to the paper tray 51, and then the paper tray 51 moves back to the working station to provide tracing paper.

[0030] Reference Figure 1 A paper pusher 53 is vertically slidably connected inside the paper tray 51. The paper pusher 53 is connected to the paper tray 51 by a vertically arranged paper pusher 54. The tracing paper is placed on the paper pusher 53. As the amount of tracing paper used gradually decreases, the paper pusher 54 pushes the paper pusher 53 to gradually rise, thereby ensuring that the height of the topmost tracing paper is always at the same position, so as to facilitate the gripping of the tracing paper.

[0031] Reference Figure 1A suction cup 52 for conveying tracing paper is movably connected to the placement rack 5. The suction cup 52 can slide horizontally and vertically via a slide rail. The suction cup 52 slides above the paper frame 51, descends to pick up the tracing paper, then rises and slides horizontally above the conveyor belt 1, descends to place the tracing paper onto the conveyor belt 1. An external robotic arm places silicon wafers onto the tracing paper, and the silicon wafer stack then passes sequentially through the leveling seat 2 and the detection seat 4.

[0032] Reference Figure 1 and Figure 2 The regulating seat 2 includes a base 21 located below the conveyor belt 11. A lifting cylinder 22 is vertically mounted on the base 21. The output shaft of the lifting cylinder 22 is connected to a lifting plate 23. A support plate 25, directly opposite the gap 12, is fixed at the center of the lifting plate 23. A sensor 26 for detecting the silicon wafer stack is mounted at the center of the support plate 25. The sensor 26 is electrically connected to the conveyor belt 1 and the lifting cylinder 22. When the sensor 26 detects the silicon wafer stack, a delay is established until the center of the silicon wafer stack is directly aligned with the sensor 26. At this point, the conveyor belt 1 stops conveying, the output shaft of the lifting cylinder 22 extends, the lifting plate 23 rises, and the support plate 25 extends from the gap 12 to lift the silicon wafer stack. A buffer 24 is vertically mounted on the base 21. When the lifting plate 23 descends, the buffer 24 provides cushioning protection for the lifting plate 23.

[0033] Reference Figure 1 and Figure 2 A pair of opposing alignment blocks 31 and a pair of opposing alignment blocks 32 are horizontally slidably connected to the lifting plate 23. The sliding directions of alignment blocks 31 and 32 are perpendicular to each other, and the two alignment blocks 31 and 32 are located around the support plate 25. Alignment blocks 31 are directly opposite the gap 12, and the two alignment blocks 32 are located on both sides of the conveyor belt 1. When the support plate 25 lifts the silicon wafer stack, the two alignment blocks 31 and 32 are positioned directly opposite the four sides of the silicon wafer stack. Alignment blocks 31 and 32 slide towards each other and press against the silicon wafer stack, thereby straightening the silicon wafer stack and improving its uniformity.

[0034] Reference Figure 1 and Figure 2 One of the regularization blocks 31 and the other 32 have a buffer block 34 connected to their opposite sides by a spring 33. The buffer block 34 buffers and protects the silicon wafer stack, preventing excessive pressure from damaging it. After regularization, the silicon wafer stack flows to the detection seat 4 via conveyor belt 1 for detection.

[0035] Reference Figure 1 , Figure 3 and Figure 4A lifting seat 43, directly opposite the gap 12, is vertically slidably connected to the center of the detection seat 4. The center of the lifting seat 43 also houses a sensor 26 for detecting the silicon wafer stack. When the sensor 26 detects the silicon wafer stack, the lifting seat 43 rises, lifting the stack. The detection seat 4 is equipped with four sets of camera groups and four sets of angled cameras 42.

[0036] Reference Figure 1 , Figure 3 and Figure 4 Each camera group includes two side cameras 41 arranged horizontally side by side. The four camera groups are located on the outside of the four sides of the silicon wafer stack, and are used to photograph and inspect the four sides of the silicon wafer stack.

[0037] Reference Figure 1 , Figure 3 and Figure 4 Four sets of angled cameras 42 are located between adjacent camera sets. The four sets of angled cameras 42 are directly opposite the four corners of the silicon wafer stack. Each set contains two angled cameras 42 that are directly opposite each other. The two angled cameras 42 in each set are tilted and located on both sides of the corner of the silicon wafer stack, which are used to capture and detect the four corners of the silicon wafer stack.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The lifting platform 43 drives the silicon wafer stack up and down. The side camera 41 and the angled camera 42 capture images of the silicon wafer stack from top to bottom to determine whether it meets the packaging requirements. After the inspection is completed, the lifting platform 43 descends and places the silicon wafer stack on the conveyor belt 1. If it meets the requirements, the conveyor belt 1 transports the silicon wafer stack forward to the next process. If it does not meet the requirements, the conveyor belt 1 rotates in the opposite direction to rearrange the wafers, or the operators can manually rearrange or remove the wafers for repair.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
