Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a double flower basket positioning and feeding device. Background Technology

[0002] With the development of photovoltaic manufacturing automation technology, a technology for automatic basket loading has emerged. This technology uses a special mechanism to grab, transfer, and position the baskets carrying photovoltaic silicon wafers, thereby improving the continuity and efficiency of the silicon wafer processing flow.

[0003] In related technologies, fixed structures or single-specification gripping devices are typically used to handle and load flower baskets in order to match the predetermined process rhythm of the production line.

[0004] However, the above-mentioned methods and related devices have the following problems: On the one hand, flower baskets are prone to wear and tear during long-term use and repeated handling, which affects positioning accuracy and silicon wafer load-bearing stability; On the other hand, the structure and size of existing feeding mechanisms are usually designed for a single model of flower basket and cannot be adapted to flower baskets of different specifications. When switching specifications, the equipment or mechanism needs to be replaced or adjusted, which increases equipment costs and debugging time. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a double flower basket positioning and feeding device, which can reduce wear caused by reciprocating handling of flower baskets and increase the stability of flower basket feeding and transfer.

[0006] The technical solution adopted in this utility model is as follows: A double flower basket positioning and feeding device, comprising: Linear module, used to drive the base plate to move linearly along its length; A base plate is set on the linear module, and two photovoltaic flower baskets are arranged side by side on the base plate along the width direction; A side-push assembly is configured on one side of each photovoltaic flower basket in the length direction. The side-push assembly includes side-push cylinders located on both sides of the photovoltaic flower basket in the width direction. A positioning baffle is set between the side thrust cylinders on both sides in the width direction; An inclined pusher component is configured on the opposite side of the length direction for each photovoltaic flower basket, and is used to push the photovoltaic flower basket closer to and against the positioning baffle; In the width direction, the photovoltaic flower basket abuts against the side thrust cylinders on both sides; Along its length, one side of the photovoltaic flower basket abuts against the positioning baffle, and the other side abuts against the inclined push component; The oblique push assembly includes an oblique push cylinder located at at least one corner of the photovoltaic flower basket along its length.

[0007] As a further improvement to the above technical solution: In one embodiment, along its length, one side of the photovoltaic flower basket further includes a sensing component, which includes at least one sensor.

[0008] In one embodiment, the sensing component includes three sets of sensors distributed along the height direction, wherein the uppermost sensor detects whether there is a silicon wafer inside the photovoltaic flower basket, and the two lower sensors detect whether there is a photovoltaic flower basket and whether the photovoltaic flower basket is placed upside down, respectively.

[0009] In one embodiment, an RFID reader is disposed above the positioning baffle, the RFID reader being used to identify the number information of the photovoltaic flower basket.

[0010] In one embodiment, the linear module includes a lead screw arranged along the length direction, a slider disposed on the lead screw, and the top of the slider being connected to a connecting plate in the height direction.

[0011] In one embodiment, the connecting plate is inclined along its length at an angle of 3 degrees to tilt the silicon wafers in the photovoltaic basket to one side while maintaining their integrity.

[0012] In one embodiment, the base plate and the connecting plate are fixed together by a connector, and the base plate moves synchronously along the length direction under the drive of the linear module.

[0013] In one embodiment, the connector uses a bolt structure.

[0014] In one embodiment, the oblique push cylinder of the oblique push assembly is located at one corner of the photovoltaic flower basket along its length, and is used to apply an oblique push force to make the photovoltaic flower basket come into close contact with the positioning baffle.

[0015] The beneficial effects of this utility model are as follows: This utility model features a compact structure. By employing a double-basket arrangement side-by-side, it enables simultaneous positioning and loading preparation of two baskets within a single work cycle. This improves the matching of loading rhythm with the production line pace, significantly enhancing overall production efficiency and equipment utilization. Furthermore, it utilizes a unique composite positioning structure combining side-push and oblique-push mechanisms. The side-push component clamps the basket from both sides along its width, eliminating gaps in that direction. Simultaneously, the oblique-push component applies a thrust from the rear side along the basket's length, forcing it to fit tightly against the fixed positioning baffle, eliminating gaps in the length direction. This multi-directional constraint mechanism works together to ensure the positioning accuracy and stability of the baskets during load-bearing and transfer processes.

[0016] This utility model also has the following advantages: The drive cylinders of the side-push and oblique-push components of this invention have a certain stroke range, and their clamping positions are not fixed. This allows the device to adapt to different widths and lengths of flower baskets within a certain range by adjusting the stroke or pressure of the cylinders; when the production line needs to switch product models, there is no need to replace mechanical parts or only minor adjustments are required, which greatly improves the flexibility of the production line and reduces changeover time.

[0017] This invention designs the connecting plate with a tilted structure at a specific angle, so that the entire basket and the silicon wafers inside are in a consistent tilted state. This pre-positioning posture ensures that the robotic arm or subsequent gripping mechanism can approach the silicon wafer at the same angle and under the same conditions every time it picks up the wafer, which greatly improves the success rate, stability and process consistency of gripping, and reduces the risk of breakage.

[0018] This invention integrates a sensing component and an RFID reader. The sensor can detect in real time whether the flower basket exists, whether it is placed correctly, and whether there is a silicon wafer inside, effectively preventing operational errors such as loading empty baskets or placing flower baskets upside down. The RFID reader can automatically identify the number of each flower basket, realizing accurate traceability and information management of the flower baskets and their contents.

[0028] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0029] like Figures 1-3 The accompanying drawing shows a structural schematic diagram of a double flower basket positioning and feeding device according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0030] This application provides a double flower basket positioning and feeding device, including a linear module 100, a base plate 200, a photovoltaic flower basket 300, a side push component 400, an oblique push component 500, a positioning baffle 600, a sensing component 700, and an RFID reader 800.

[0031] In some embodiments, the linear module 100 provides linear motion along the length direction; Specifically, the linear module 100 includes a lead screw 110 precisely arranged along the length direction, and a slider 120 is fitted on the lead screw 110. The slider 120 can move along the axial direction when the lead screw 110 rotates. The top of slider 120 is fixedly connected to a connecting plate 130 in the height direction; It is worth emphasizing that the connecting plate 130 is designed to have a small tilt angle along its length, preferably 3 degrees; This tilting structure ensures that all load-bearing components subsequently installed on the connecting plate 130 maintain the same tilt angle. The purpose is to allow the silicon wafers inside the photovoltaic basket 300 to naturally tilt to one side under the action of gravity and maintain a stable and consistent posture. This creates optimal conditions for the subsequent robotic arm to grasp the silicon wafers, significantly improving the success rate of grasping and process consistency.

[0032] In some embodiments, the base plate 200 is securely mounted on the inclined connecting plate 130 by means of connectors (e.g., bolts), thereby inheriting its 3-degree tilt angle; Driven by the linear module 100, the base plate 200 can perform precise reciprocating motion along the length direction; On the upper surface of the base plate 200, two photovoltaic baskets 300 for carrying photovoltaic silicon wafers are arranged side by side along the width direction. This dual-station layout allows the device to process two baskets simultaneously in one work cycle, greatly improving loading efficiency and equipment utilization.

[0033] In some embodiments, each flower basket is equipped with an independent positioning system, which mainly includes: The side-push component 400 is configured on one side of each photovoltaic flower basket 300 along its length direction. It mainly includes two side-push cylinders located on both sides of the photovoltaic flower basket 300 in the width direction. The two side-push cylinders move synchronously to clamp the photovoltaic flower basket 300 from both sides, thereby eliminating the displacement gap in the width direction and achieving precise positioning in the width direction. The inclined push assembly 500 and the positioning baffle 600, wherein the inclined push assembly 500 includes at least one inclined push cylinder disposed at the rear corner of the photovoltaic flower basket 300. Meanwhile, a positioning baffle 600 is fixedly installed between the two side-push cylinders of the side-push component 400. When the oblique push cylinder is working, it applies an oblique thrust to the photovoltaic flower basket 300, forcing it to move in the length direction until its side is tightly attached to the positioning baffle 600; The positioning baffle 600 serves as a fixed mechanical reference surface, ensuring consistent positioning of all flower baskets along their length.

[0034] The width direction clamping of the aforementioned side-push component 400, together with the length direction positioning completed in conjunction with the oblique push component 500 and the positioning baffle 600, constitutes a multi-directional constraint composite positioning mechanism. This ensures that the photovoltaic flower basket 300 is reliably restricted in both degrees of freedom in the plane during the movement and loading process, thereby achieving extremely high positional accuracy and stability.

[0035] In addition, in some embodiments, a sensing component 700 is also included, which is installed on one side of the photovoltaic flower basket 300 along its length (typically near the positioning baffle 600).

[0036] In a preferred embodiment, the sensing component 700 includes three sets of sensors distributed along the height direction; The sensor at the top is used to detect whether there are silicon wafers inside the photovoltaic flower basket 300; The sensors in the middle and at the bottom are used to detect whether a photovoltaic flower basket 300 is placed at the workstation and whether the photovoltaic flower basket 300 is placed correctly (i.e., anti-reverse detection).

[0037] In some embodiments, an RFID reader 800 is installed above the positioning baffle 600, and each photovoltaic flower basket 300 is typically equipped with an RFID tag that stores information such as its number and specifications. When the flower basket is pushed to fit against the positioning baffle 600, the RFID reader 800 can read the tag information at close range, realizing automatic identification of the flower basket and traceability of production data.

[0038] In practical applications, the workflow of this utility model is as follows: At the beginning of the installation, the photovoltaic flower baskets 300 at the two workstations are precisely positioned and clamped by the side-push component 400 and the oblique-push component 500; The linear module 100 starts, driving the entire base plate 200 and the basket above it to move to the loading station; During this period, the sensing component 700 verifies the status of the flower basket and silicon wafer in real time, and the RFID reader 800 completes information collection. Once it reaches the designated position, the external robotic arm can pick up the silicon wafer from the basket at a preset, consistent tilt angle for subsequent process steps.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
