[0030] In the present application, on-line weighing refers to weighing materials in production, directly feeding the weight of the materials to the production department through an electrical weighing system, and off-line weighing refers to weighing materials stored or about to be put into production to facilitate procurement statistics and the like, and the weighing data is saved offline. The former requires quick flow of materials in production on the production line, and the production line is a clean space, so the weighing time is short and the weighing environment is high.

[0031] Figures 1 to 4 An embodiment of the on-line weighing tray of the present application is schematically shown.

[0032] As Figures 1 to 4 shown, the present application discloses an online weighing tray, comprising: a tray assembly 1, the tray assembly 1 comprising: a tray support 11, a support column 12 and a positioning column 13. The support column 12 is symmetrically arranged on the left and right sides of the tray support 11. The front and rear ends of the tray support 11 are provided with positioning columns 13, and the positioning columns 13 are arranged in a diagonal direction on the tray support 11. The top of the positioning column 13 is provided with a protruding positioning plug 14. A weighing assembly 2 is connected below the tray assembly 1 and electrically connected with an electrical weighing system.

[0033] Through the above structural design, the embodiment of the present application sets the support column 12 on the left and right sides of the tray support 11 and the positioning column 13 at the front and rear ends, so that the tray support 11 can stably support the online transport trolley from multiple points and accurately dock with the bottom plate of the online transport trolley, realizing stable vehicle body and accurate weighing. At the same time, the present application also electrically connects the weighing assembly 2 with the electrical weighing system to realize online transmission of weighing data, so as to ensure the sequential production of the liquid crystal substrate production line. Among them, the positioning columns 13 are arranged in a diagonal direction at the front and rear ends of the tray support 11 to realize reliable positioning of the transport trolley bottom plate. The positioning plug 14 is connected with the positioning hole of the transport trolley bottom plate in a plug-in manner to realize quick docking, which can adapt to the high-speed continuous production environment of the production line, avoid displacement and shaking of the material during rapid loading, weighing and transfer, and thus ensure accurate and rapid weighing of the material.

[0034] In some embodiments of the present application, as Figures 1 to 3 shown, the tray support 11 is a strip structure, and the left and right sides of the strip structure of the tray support 11 extend transversely to form a plurality of first support tables 111, which are arranged one by one with the support columns 12, so as to install multiple sets of support columns 12 to support the bottom plate of the transport trolley. The front and rear ends of the strip structure of the tray support 11 extend to the left and right sides respectively to form a second support table 112, which is arranged one by one with the positioning columns 13, so as to install the front and rear positioning columns 13 respectively to realize reliable positioning of the transport trolley and avoid displacement of the transport trolley during the short weighing time. Among them, as Figure 1 , Figure 2 and Figure 4 shown, the top of the support column 12 and the positioning column 13 is a circular planar structure, which can play a stable supporting role. The center of the positioning column 13 is provided with a protruding positioning plug 14, which can be plugged with the bottom plate of the transport trolley to realize vehicle body positioning. Referring to Figure 2 and Figure 3 shown, in the embodiment of the present application, the overall shape of the tray support 11 is an S-shaped shape with a fishbone, so that the installation positions of the support columns and the positioning columns are more dispersed, thereby improving the stability of the support and positioning.

[0035] In some embodiments of the present application, as shown in Figure 1 and Figure 3 , the lower side of the first support platform 111 and the second support platform 112 are each provided with a circular arc thinning transition section. Through the circular arc thinning transition section, the thickness of each support platform can be thinned relative to the backbone portion of the tray support 11, while ensuring that the structural strength of the connection site meets the requirements, thereby facilitating the punching installation of the support column 12 and the positioning column 13, and at the same time, lightening the overall weight of the tray support 11.

[0036] In some embodiments of the present application, as shown in Figure 1 , Figure 3 and Figure 4 , the first support platform 111 and the second support platform 112 are each provided with a first threaded hole 113, and a first fastening bolt 15 is screwed into the first threaded hole 113. The support column 12 and the positioning column 13 are connected to the corresponding support platform through the first fastening bolt 15. The support column 12 and the positioning column 13 are also provided with a first fastening nut 16 between them and the corresponding support platform, which is used to fix the first fastening bolt 15 to adjust the installation height of the support column 12 and the positioning column 13. When assembling, the first fastening bolt 15 is inserted into the first threaded hole 113, and by loosening the first fastening nut 16 to move it away from the support platform, the first fastening bolt 15 can be loosened, thereby rotating to adjust the height. After the height adjustment of the first fastening bolt 15 is completed, the first fastening nut 16 is tightened again to make it tightly adhere to the support platform, which can fix the position height of the first fastening bolt 15 by hindering its downward rotation.

[0037] In some embodiments of the present application, the tray support 11 is made of aluminum alloy material, and the surface is polished and naturally anodized to remove burrs and sharp corners, and the surface is enhanced to improve corrosion resistance, thereby prolonging the service life while avoiding the pollution of the liquid crystal substrate production workshop caused by corrosion debris.

[0038] In some embodiments of the present application, as shown in Figures 1 to 3As shown, the center of the tray support 11 is provided with a sink 115, which on the one hand further reduces the material weight of the tray assembly 1, and on the other hand thins the connection position of the tray support 11 and the weighing assembly 2 to facilitate drilling connection. The bottom of the sink 115 is provided with a plurality of second threaded holes 116, and a second fastening bolt (not shown) is screwed in the second threaded hole 116. The tray support 11 and the weighing assembly 2 are fixedly connected through the second fastening bolt.

[0039] In some embodiments of the present application, as shown in Figure 4 As shown, the positioning column 13 is a hollow structure with an open top, and the side of the positioning plug 14 is provided with a cover plate. The cover plate and the positioning plug 14 can be an integral molding structure, and the cover plate is covered at the top opening of the positioning column 13 to form a support plane and stabilize the positioning plug 14. As shown in Figure 4 As shown, the cover plate and the top side wall of the positioning column 13 are connected by bolts to achieve fixed installation of the positioning plug 14 on the positioning column 13.

[0040] In some embodiments of the present application, the support column 12 and the positioning column 13 are both made of aluminum alloy material, and the surface is polished and naturally anodized to remove burrs and sharp corners, improve corrosion resistance, and ensure that the surface is clean and no debris is generated, thereby meeting the cleanliness requirements of the liquid crystal substrate production workshop.

[0041] In some embodiments of the present application, the positioning plug 14 is made of steel material, and the surface is polished to remove burrs and sharp corners, and is also quenched and blued to have higher lightness, which can ensure that the surface is clean and no debris is generated after multiple uses, thereby meeting the cleanliness requirements of the liquid crystal substrate production workshop.

[0042] In some embodiments of the present application, as shown in Figure 1 As shown, the weighing assembly 2 includes a connecting disc 21, a weighing sensor 22, and a wiring terminal 23. The weighing sensor 22 is fixedly connected to the tray assembly 1 through the connecting disc 21, and the weighing sensor 22 is also electrically connected to the electrical weighing system through the wiring terminal 23 to send the electrical signal generated by the weighing to the electrical weighing system to realize online weight detection. The weighing sensor 22 can adopt various types of sensors sold on the market, such as a piezoelectric sensor, which generates a standard current signal of 4-20mA, which can be collected and read by the acquisition board of the upper computer. Since the weighing sensor 22 itself is not the improvement point of the present application, it will not be described in detail here.
