Description

Technical Field

[0001] The utility model belongs to the technical field of weighing and feeding, and in particular relates to a weighing and feeding mechanism for producing photovoltaic cell texturing additives. Background Art

[0002] Photovoltaic cell texturing is a process for treating solar-grade silicon wafers. It is a process in the production of silicon solar cells. Texturing additives need to be added during photovoltaic cell texturing.

[0003] The traditional weighing and feeding mechanism used for adding texturing additives has a fixed discharging position, so the additive can only be added from one place. If the stirring is not timely, it is likely to cause uneven distribution of the texturing additive, thus affecting the texturing. In addition, the traditional weighing and feeding mechanism usually does not have a screening function, and it needs to be screened by screening equipment before feeding. Moreover, if the sieve holes are blocked during screening, special equipment is required to clear the blockage, which makes the equipment complicated and the cost is high. In order to solve the above problems, a weighing and feeding mechanism for the production of photovoltaic cell texturing additives is provided.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a weighing and feeding mechanism for the production of photovoltaic cell texturing additives. By starting the second motor, the bottom of the material storage barrel is adjusted to face downward. By starting the second motor, the material storage barrel can be controlled to swing left and right, and the texturing additives inside can be screened into the position to be added. The position to be added can be adjusted by the cooperation of the first motor and the second cylinder, thereby improving the uniformity of the fabric.

[0006] To achieve the above-mentioned purpose, the utility model proposes a weighing and loading mechanism for the production of photovoltaic cell texturing additives. The weighing and loading mechanism includes a fixed seat, a vertical first cylinder is fixed above the fixed seat, an elastic telescopic part is fixed on the output shaft of the first cylinder, an adjusting component is fixed above the elastic telescopic part, and a storage component for storing the texturing additive is fixed on the adjusting component.

[0008] The material storage assembly comprises a material storage barrel, and the bottom of the material storage barrel is provided with sieve holes distributed in an array.

[0009] Furthermore, the elastic telescopic member includes a rod sleeve fixed on the output shaft of the first cylinder, a sliding rod is sleeved on the upper end of the rod sleeve, an adjustment component of the sliding rod is fixed above the sliding rod, and a spring is fixedly connected between the adjustment component and the rod sleeve.

[0010] Furthermore, a distance sensor for detecting the length of the spring is fixed on the rod sleeve.

[0011] Furthermore, a barrel cover is installed on the material storage barrel.

[0012] Furthermore, the barrel cover and the material storage barrel are threadedly matched.

[0013] Furthermore, a handle is fixed on the barrel cover.

[0015] Furthermore, the control component includes an L-shaped bracket, a support plate is fixed below the top plate of the L-shaped bracket, and second protrusions distributed in a circumferential array are fixed below the support plate, and the second protrusions are used to squeeze the first protrusions.

[0016] The weighing and feeding mechanism for producing photovoltaic cell texturing additives proposed by the utility model can bring the following beneficial effects:

[0017] 1. The feeding mechanism of the utility model adjusts the bottom of the material storage barrel downward by starting the second motor, and the material storage barrel can be controlled to swing left and right by starting the second motor, so that the texturing additive in it can be screened into the position to be added. The position to be added can be adjusted by the cooperation of the first motor and the second cylinder, thereby improving the uniformity of the cloth;

[0018] 2. The feeding mechanism of the utility model starts the second motor to control the bottom of the material storage barrel to be adjusted upward, stops feeding, starts the first cylinder to control the top of the first protrusion to be adjusted to be higher than the bottom of the second protrusion, and starts the first motor to control the rotation of the first protrusion. Under the action of the second protrusion, the first protrusion shakes up and down, thereby making the material storage barrel shake up and down, and the velvet-making additive that is blocked by the sieve holes falls into the material storage barrel, which can dredge the sieve holes. Therefore, the weighing and feeding mechanism can not only detect the weight of the material through the elastic telescopic part, but also can combine the first protrusion and the control component to realize the shaking of the material storage barrel, thereby realizing the dredging function, so that one machine can be used for multiple purposes and reduce equipment costs.
