Description
Technical Field
The invention belongs to the technical field of solar cell processing, and particularly relates to multifunctional dispensing equipment for solar cells.
Background
In the production of solar cells, a dispenser is usually required to dispense the solar cells.
The dispenser is also called a glue spreader, a glue dispenser, a glue filling machine and the like, and is specially used for controlling the fluid. And the fluid is dripped and coated on the surface of the product or an automatic machine inside the product, so that three-dimensional and four-dimensional path dispensing, accurate positioning, accurate glue control, no wire drawing, no glue leakage and no glue dripping can be realized. The glue dispenser is mainly used for accurately dispensing, injecting, coating and dripping glue, paint and other liquids in a product process to each accurate position of a product, and can be used for realizing dispensing, line drawing, circular or arc.
The common glue dispenser is to send compressed air into a glue bottle (syringe) to press glue into a feeding tube connected with a piston chamber, when the piston is in an up stroke, the piston chamber is moderately filled with glue, and when the piston pushes a glue dripping needle downwards, the glue is pressed out from a needle nozzle. The amount of glue dropped is determined by the distance the piston is undershot, and can be manually adjusted or controlled in software. However, the form of compressed air is usually affected by the temperature, and in the continuous operation process of the apparatus, the overall temperature of the apparatus is continuously increased to cause the expansion of air, so that the glue yield is slightly higher than the theoretical value, and the glue yield is larger, so that the glue yield is gradually increased along with the operation of the apparatus, and the increase of the glue yield affects the deviation of the glue dispensing position and causes more glue waste.
Disclosure of Invention
The invention provides the adjustable multifunctional dispensing equipment for the solar cell, which overcomes the defects of the prior art and has uniform glue discharging and high stability.
In order to achieve the purpose, the invention adopts the following technical scheme: a multifunctional dispensing device for solar cells comprises a conveying table arranged on the ground, racks arranged on two sides of the conveying table, a working frame arranged on the racks, a dispensing device arranged on the working frame, and a transmission structure used for controlling the dispensing device; the glue dispensing device comprises a moving block capable of moving back and forth on the working frame, a first air cylinder arranged below the moving block, a fixed disc arranged at the top end of the first air cylinder, a connecting block rotatably arranged below the fixed disc, a glue gun rotatably arranged below the connecting block, a telescopic structure arranged in the connecting block and used for extruding the glue gun, a transmission gear arranged on the outer wall of the connecting block and an adjustable power assembly arranged on one side of the glue gun. When the glue dispensing device is moved to the starting point position by the transmission structure, the first air cylinder moves downwards to drive the glue gun to move downwards, when the glue gun is in place, the adjustable power assembly drives the transmission teeth on the outer wall of the connecting block to rotate so as to enable the connecting block to rotate, the rotation of the connecting block controls the telescopic structure to realize the extension or shortening operation, when the telescopic structure extends, the glue gun is extruded, and the extruded glue gun performs uniform and compact glue discharging. The glue outlet uniformity is ensured, multiple glue dispensing modes are provided through the arrangement of the adjustable power assembly, and the working adaptability of the equipment is improved.
