Description

Technical Field

[0001] This utility model relates to the field of material feeding equipment technology, and in particular to a multi-station material feeder for a BC battery cell mounting machine. Background Technology

[0002] During the loading process of BC solar cells into a chip mounter, high requirements are placed on the consistency of the pick-up position, the loading cycle time, and the protection of the cells. Existing feeders are mainly of three types:

[0003] 1) Fixed depth type: The loading capacity of the battery cells is limited, and frequent replenishment is required; the suction rod needs to descend a large stroke each time and the depth is not constant, which can easily cause fluctuations in the material picking speed and the risk of collision between the suction rod and the battery cells, resulting in a decrease in yield.

[0004] 2) Tray type: Multiple trays are used to hold a small number of battery cells. The picking position and depth change with the number of remaining cells. The trays need to be changed frequently, the cycle time is unstable, and there are also problems such as easy damage to the nozzle rod and damage to the battery cells.

[0005] 3) Overall automatic lifting type: The overall capacity is still relatively small, and most of them are single-station joint lifting, making it difficult to achieve on-demand material supply for each station; the material extraction depth is inconsistent with the stack height, and it is difficult to automatically unify and quickly calibrate the material extraction height.

[0006] Therefore, how to provide a feeder structure that combines "large capacity, adjustable clamping / limiting, flexible feeding at different stations, and uniform suction height" without increasing the complexity of pick-and-place machine material handling is an urgent problem that the industry needs to solve. Utility Model Content

[0007] The purpose of this invention is to provide a multi-station feeder for a BC cell chip mounter, which significantly improves the consistency of material feeding and the stability of the equipment cycle time. It can quickly adjust the limit distance according to the size of the cell, accommodates large-capacity feeding, and reduces downtime and manual intervention.

[0008] To achieve the above objectives, the following technical solution is adopted:

[0009] A multi-station feeder for a BC solar cell placement machine includes multiple feeding positions, each feeding position having a feeding device. The feeding device includes a material box, a lifting mechanism extending vertically through the material box, and a feeding drive mechanism for driving the lifting mechanism to move up and down. The lifting mechanism is used to lift the BC solar cells in the material box to the feeding height. The material box includes a material box base, a length adjustment limit rod on each of two opposite sides of the material box base, and a width adjustment limit rod on each of two opposite sides of the material box base. The length adjustment limit rod and the width adjustment limit rod are slidably connected to the material box base to accommodate BC solar cells of different sizes.

[0010] Preferably, the lifting mechanism includes a feeding lifting shaft arranged in a vertical direction and a feeding lifting block disposed at the top of the feeding lifting shaft.

[0011] Preferably, the feeding lifting block includes a lifting base block and a plurality of support rods spaced apart around the lifting base block.

[0012] Preferably, the feeding drive mechanism includes a feeding timing belt assembly and a feeding guide assembly arranged in a vertical direction, as well as a feeding drive component that is driven to connect with the feeding timing belt assembly; the lifting mechanism is connected to the feeding timing belt assembly and the feeding guide assembly via a connecting block.

[0013] Preferably, the feeding guide assembly includes a feeding guide slide rail and a feeding guide slider slidably connected to the feeding guide slide rail; the feeding guide slider is connected to the connecting block.

[0014] Preferably, the material box base has a lifting hole in the middle corresponding to the lifting mechanism, so that the lifting mechanism can move through to achieve up and down movement; the material box base has a length adjustment sliding hole along its length direction corresponding to each length adjustment limit rod, and a width adjustment sliding hole along its width direction corresponding to each width adjustment limit rod.

[0015] Preferably, the feeder further includes a frame; the material box is installed on the top of the frame, and the feeding drive mechanism is located below the material box.

[0016] Preferably, a fixing plate is connected to the same end of all the material boxes; the top of the fixing plate is provided with a feeding detection optical fiber corresponding to each material box.

[0017] By adopting the above solution, the beneficial effects of this utility model are:

[0018] This invention provides a multi-station feeder for a BC battery cell pick-and-place machine. By incorporating a lifting mechanism, it elevates the battery cells in the material box one by one to a preset height on the pick-and-place machine's nozzle rod, preventing fluctuations in the nozzle rod's stroke with the remaining number of cells and significantly improving material handling consistency and equipment cycle stability. Simultaneously, by incorporating length and width adjustment limit rods that slide with the material box base, the limit distance can be quickly adjusted according to the battery cell size, forming a "spring clip" adjustable structure. This reduces tooling changes between machine types and expands compatibility with various machine models and cell types. Furthermore, with multiple feeding stations each equipped with an independent feeding device, seamless switching to other stations is possible when one station is short of material. It also allows for "parallel simultaneous feeding" or "sequential feeding" depending on production line strategy, accommodating large-capacity feeding and reducing downtime and manual intervention.

The length adjustment limiting rods 12 and 13 are slidably connected to the material box base 11 to accommodate BC solar cells of different sizes. By slidably connecting the length adjustment limiting rods 12 and 13 to the material box base 11, a spring-loaded structure is formed, allowing the material box 1 to accommodate solar cells of adjustable length (0-80mm) and width (0-35mm). Multiple feeding devices enable multi-station feeding, each controllable independently. Multiple material boxes 1 can be fed simultaneously or sequentially.

[0039] When using the sequential feeding mode, if a single tray 1 is empty, the pick-and-place machine's nozzle rod can switch to the next tray 1 for feeding. During feeder operation, one tray 1 is fed, while the other trays 1 serve as reserve trays. The reserve trays can be filled with materials and ready for material changeover, reducing machine material changeover time. Each tray can hold more than 500 pieces.

[0040] The lifting mechanism 2 includes a vertically oriented feeding lifting shaft 21 and a feeding lifting block located at the top of the feeding lifting shaft 21.

By setting the lifting mechanism 2 to lift the battery cells in the material box 1 one by one to the preset height of the pick-and-place machine's nozzle rod, the suction height of the pick-and-place machine's nozzle rod can be standardized.

[0041] The feeding drive mechanism 3 includes a feeding synchronous belt assembly 31 and a feeding guide assembly 32 arranged vertically, as well as a feeding drive component 33 drivenly connected to the feeding synchronous belt assembly 31; the lifting mechanism 2 is connected to the feeding synchronous belt assembly 31 and the feeding guide assembly 32 via a connecting block.

[0042] Furthermore, the feeding drive component 33 is a feeding drive motor; the feeding synchronous belt assembly 31 includes a driven pulley, a drive pulley connected to the feeding drive motor, and a synchronous belt connecting the drive pulley and the driven pulley. The feeding guide assembly 32 includes a feeding guide slide rail and a feeding guide slider slidably connected to the feeding guide slide rail; the feeding guide slider is connected to the connecting block.

[0044] In addition, the feeder also includes a frame 4; the material box 1 is installed on the top of the frame 4, and the feeding drive mechanism 3 is located below the material box 1. Furthermore, the frame 4 has a T-shaped cross-section, wherein the vertical end of the T-shape of the frame 4 is the chassis, and the feeding drive mechanism 3 is installed inside the vertical end of the T-shape of the frame 4. Furthermore, a circuit drive control board is also provided inside the vertical end of the T-shape of the frame 4.

[0045] All material boxes 1 are connected to a fixing plate 5 at the same end; the top of the fixing plate 5 is provided with a feeding detection fiber optic cable 6 corresponding to each material box 1.
