Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to an online weighing component for photovoltaic frames used for applying adhesive in photovoltaic processing production lines. Background Technology

[0002] Photovoltaic modules are fitted with frames around their perimeter. Before installation, the frames need to be glued into grooves using a glue applicator. In existing technology, the air pressure of the glue applicator is unstable during the initial glue application, which can easily lead to insufficient glue filling. Usually, the amount of glue on the frames is monitored by manually weighing them before and after glue application. However, manual operation involves a large contact area with the workpiece, which significantly interferes with the weighing process and can easily lead to inaccurate weighing. Utility Model Content

This online weighing component for photovoltaic frames can realize real-time weighing of long strip-shaped workpieces with minimal contact area with the workpiece and minimal interference to the workpiece, and has good weighing accuracy.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an online weighing component for a photovoltaic frame, comprising: a left substrate and a right substrate. At least one left weighing sensor is installed on the upper surface of the left substrate, and at least one right weighing sensor corresponding to the left weighing sensor is installed on the upper surface of the right substrate. One end of each of the left and right weighing sensors, which are symmetrically arranged in pairs, is installed on the left and right substrates, and the other end of each extends towards the outside of the left and right substrates. A deformation sensing area is provided between the two ends of each of the left and right weighing sensors, and the deformation sensing area is located on the outside of the left and right substrates. A pad is installed on the upper surface of the left and right weighing sensors at their respective ends, and the upper surface of the pad is used to overlap and contact the lower surface of one end of the strip workpiece.

[0005] The following are further improvements to the above technical solution:

[0006] 1. In the above scheme, the pad is an elastic pad.

[0007] 2. In the above solution, the pad is one of a silicone pad, a rubber pad, or a polyurethane pad.

[0008] 3. In the above scheme, both the left and right weighing sensors are parallel beam type sensors.

[0009] 4. In the above scheme, the pad includes a main body connected to the left and right weighing sensors and an extension extending forward and backward from the upper part of the main body, respectively.

[0010] 5. In the above scheme, there are four left and four right weighing sensors.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] The online weighing component for photovoltaic frames of this utility model has a weighing sensor installed on the upper surface of both the base plate and the right base plate. Two symmetrically arranged weighing sensors have one end installed on the left base plate and the right base plate, and the other end of each extends towards the outside of the left base plate and the right base plate. A deformation sensing area is provided between the two ends of the weighing sensor and is located on the outside of the left base plate and the right base plate. A pad is installed on the upper surface of the end of the weighing sensor away from the left base plate and the right base plate.
