Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing and weighing, in particular to an online weighing structure of a photovoltaic frame glue coating machine. Background Art

[0002] In the photovoltaic industry, the photovoltaic frame needs to be glued. After the existing online glue coating machine lifts up the photovoltaic frame and applies glue, it is also necessary to weigh the amount of glue on the frame to detect whether it meets the qualified standards. Usually, the sensor of the existing weighing structure is installed in a fixed position. There are two sensors corresponding to each frame, which are installed on the bottom plates on both sides of the gluing position. When weighing is required, the transfer module puts the frame on the V-blocks of the weighing modules on both sides, the equipment stops running, weighs the empty frame, and records the value. After completion, the transfer module lifts up the frame and moves it to the gluing position to place the material and apply glue. After gluing, the transfer module lifts up the frame again and puts it on the weighing V-block for weighing, records the value, and the transfer module lifts up the frame and moves it to the unloading position to complete the weighing of the glue amount. However, the frame glue coating weighing structure on the existing glue coating machine is installed in a fixed position and cannot achieve real-time weighing. The frame needs to be moved to the next position or the next workstation for weighing and testing. Stopping the workstation for weighing affects continuous production and consumes a long time, affecting the overall production efficiency. In addition, each frame requires two sensors, which has a higher cost. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0021] like Figure 1-3 As shown, in this embodiment, an online weighing structure of a photovoltaic frame glue coating machine is provided, which is mainly composed of a lifting cylinder 1, a cylinder mounting sheet metal 10, a material dividing connecting plate 2, a weighing pressure sensor 3, a weighing mounting plate 4, a V-shaped support block 5 and other components. Among them, the cylinder mounting sheet metal 10 is fixedly installed on the lifting cylinder 1 in an L shape, and the side plate of the cylinder mounting sheet metal 10 can be directly installed on the transfer module of the online glue coating machine or in the machine platform of the glue coating machine through screws to complete the assembly of the lifting mechanism.

[0022] Specifically, the output end of the lifting cylinder 1 faces upward, and the material distribution connection plate 2 is arranged at the output end of the lifting cylinder 1. For the convenience of installation, a floating joint 11 is arranged at the output end of the lifting cylinder 1, and the material distribution connection plate 2 is installed through the floating joint 11. The weighing pressure sensor 3 can specifically adopt the MT1022-5KG weighing sensor. The weighing pressure sensor 3 is arranged at the bottom of the material distribution connection plate 2. One fixed end of the weighing pressure sensor 3 is installed at the bottom of the material distribution connection plate 2 by screws, and the other pressure sensing end of the weighing pressure sensor 3 passes upward through the central avoidance hole of the material distribution connection plate 2 and is connected to a weighing pad 30. The weighing installation plate 4 is installed on the top of the weighing pad 30 by screws, and the weighing pad 30 can be raised to facilitate the installation of the weighing installation plate 4. At the same time, in order to place the support frame product 9, a profile 40 is set at both ends of the top of the weighing installation plate 4 for transitional padding, and two V-shaped support blocks 5 are installed and locked on the profile 40 at both ends by T-shaped nuts.

[0023] Through the above design, it can be seen that the weighing pressure sensor 3 is integrated into the lifting structure in this embodiment. In this way, when working, the lifting cylinder 1 can drive the material distribution connecting plate 2, the weighing pressure sensor 3 and the weighing installation plate 4 to lift up, and the frame product 9 is placed through the V-shaped support block 5 on the weighing installation plate 4. The pressure sensing end of the weighing pressure sensor 3 feels the pressure of the frame product 9 and can output the weight of the frame product 9 in time, realizing real-time detection, and clearing and calibrating the empty frame before gluing. After gluing, the glue weight on the frame product 9 can be accurately measured, and real-time weighing can be realized. The weight can be read intuitively to determine whether the glue amount is qualified; in conjunction with the loading and unloading module on the machine, the weight can be read whether it is in the moving process or in the stopped state, and real-time detection can be realized. Especially when it is in online continuous production, the glue amount can be quickly read by real-time weighing, which consumes very little time, and can realize continuous production of the gluing station, thereby improving the overall production efficiency. In addition, this embodiment integrates the weighing pressure sensor 3 with the online lifting structure, which has a compact structure and can move with the lifting structure and the transfer module, effectively saving space inside the glue coating machine; and each line frame only needs one weighing sensor to be installed in the center, which can reduce manufacturing costs.

[0024] It is worth mentioning that the weighing pad 30 in this embodiment is connected to the middle position of the bottom of the weighing mounting plate 4. In this way, the stability of the weighing pad 30 supporting the weighing mounting plate 4 can be improved, and the accuracy of the final measurement of the rubber weight can be improved.

[0025] In order to improve the alignment of the material distribution connecting plate 2 when it is lifted and lowered, a material distribution bottom plate 6 is fixedly connected to the cylinder mounting sheet metal 10 of this embodiment by screws. The material distribution bottom plate 6 is located directly below the material distribution connecting plate 2. Linear bearings 7 are installed at both ends of the material distribution bottom plate 6. At the same time, guide shafts 20 are provided at the bottom of both ends of the material distribution connecting plate 2, and the two guide shafts 20 are respectively slidably matched in the two linear bearings 7. In this way, when the material distribution connecting plate 2 moves up and down, the guide shaft 20 and the linear bearing 7 can form a guide limit to ensure the alignment and stability when it is lifted and lowered, and prevent the shaking of the mechanism.

[0026] In addition, in order to facilitate the detection of the placement of the frame product 9 during online production, a capacitive sensor 8 for sensing the frame product 9 is also installed on the profile 40 of the weighing installation plate 4 in this embodiment. At the same time, in order to prevent the floating joint 11 from interfering with the weighing installation plate 4, an avoidance hole 41 for avoiding the floating joint 11 is also opened on the weighing installation plate 4 in this embodiment to ensure the safety of the mechanism.
