Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. Such as "horizontal" simply means that its orientation is more horizontal than "vertical".
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
Referring to fig. 1, the present embodiment provides a glass substrate weighing apparatus, which includes a frame 10, a height adjusting mechanism 20 and a weighing platform 30, wherein the frame 10 is connected to the weighing platform 30 through the height adjusting mechanism 20, the height adjusting mechanism 20 is used to adjust a distance between the weighing platform 30 and the frame 10, and the weighing platform 30 is provided with a mass sensor.
It should be noted that, firstly, the height adjusting mechanism 20 is used to adjust the distance between the weighing platform 30 and the rack 10, so that when the liquid crystal glass substrate reaches the weighing station of the production line, the height adjusting mechanism 20 can adjust the weighing platform 30 to the weighing station, and further lift the liquid crystal glass substrate by the weighing platform 30 of the liquid crystal glass substrate weighing device 100, thereby realizing the weight measurement of the liquid crystal glass substrate.
Secondly, the weighing platform 30 should be provided with a mass sensor to enable the weighing platform 30 to have a weight detection function, and specifically, the structural form or the arrangement form of the mass sensor can be designed by those skilled in the art according to needs, for example, the mass sensor can be arranged on the surface of the weighing platform 30. The present application does not specifically limit this as long as the weighing station 30 is equipped with a mass sensor that can perform the weighing function.
Thirdly, the liquid crystal glass substrate weighing apparatus 100 is disposed below a weighing station of a production line when the liquid crystal glass substrate is weighed, and in an initial state, a distance between the weighing platform 30 and the frame 10 is smaller than a height from the weighing station to the ground. That is, in the initial state or when weighing is not needed, the weighing device of the liquid crystal glass substrate is hidden below the weighing station, so that the normal production process of the whole production line cannot be influenced; when weighing is needed, the height adjusting mechanism 20 adjusts the distance between the weighing platform 30 and the rack 10, so that the weighing platform 30 slowly lifts the liquid crystal glass substrate (if the liquid crystal glass substrate is arranged on the trolley, the trolley carrying the liquid crystal glass substrate is lifted), thereby realizing the weighing operation.
Fourth, the height adjusting mechanism 20 may be controlled by a pure machine or an electric control, and the control method is not particularly limited as long as the height adjustment is achieved.
In summary, the liquid crystal glass substrate weighing apparatus 100 of the present application can conveniently control the distance between the weighing platform 30 and the frame 10 by adjusting the height adjusting mechanism 20 due to the height adjusting mechanism 20. When the liquid crystal glass substrate is weighed, the weighing platform 30 can jack up the liquid crystal glass substrate at the weighing station of the production line, and then the weight information of the liquid crystal glass substrate is measured by the mass sensor of the weighing platform 30. Thus, when the liquid crystal glass substrate weighing device 100 measures the weight of the liquid crystal glass substrate on line, the liquid crystal glass substrate can be jacked up through the weighing platform 30, so that the liquid crystal glass substrate is separated from the production line, and further the dynamic load interference of the production line when the liquid crystal glass substrate measures the weight is avoided, therefore, the liquid crystal glass substrate weighing device 100 can reduce the error of the liquid crystal glass substrate in the on-line weighing to a certain extent compared with the prior art, thereby improving the weighing precision of the liquid crystal glass substrate, and further improving the production quality of the liquid crystal glass substrate.
In this embodiment, the frame 10 includes a first support frame 11 connected to the height adjusting mechanism 20, and two support frames 12 respectively extending from two opposite sides of the first support frame 11 toward a side away from the weighing platform 30.

In this embodiment, the height adjusting mechanism 20 includes a driving mechanism 21 and a scale platform 22 connected to the driving mechanism 21, the driving mechanism 21 is connected to the first platform 11, and the scale platform 22 is connected to the weighing platform 30. For example, the driving mechanism 21 may be any one of a cylinder, a linear motor, and the like.
It should be noted that, in order to reduce the overall volume of the liquid crystal glass substrate weighing apparatus 100, in this embodiment, a position limiting hole is disposed at a position of the first bearing table 11 corresponding to the driving mechanism 21, and the driving mechanism 21 is disposed in the position limiting hole in a penetrating manner and connected to the first bearing table 11 in a limiting manner.
Further, in order to allow the levelness of the weighing table 30 to be finely adjusted, the accuracy of the liquid crystal glass substrate weighing apparatus 100 is improved. In this embodiment. The weighing platform 22 includes a second platform 221 and two screws 222 respectively screwed to two opposite sides of the second platform 221, one ends of the two screws 222 far away from the second platform 221 are respectively connected to the weighing platform 30, and the weighing platform 22 adjusts the levelness of the weighing platform 30 through the two screws 222. It should be understood that the second loading platform 221 should be provided with a screw hole corresponding to the screw 222, so that the screw 222 can be screwed into the screw hole. In addition, the present embodiment further includes a nut, which can be screwed on the screw 222, and an end surface of the nut close to the weighing platform 30 abuts against one surface of the second bearing platform 221. In this way, the connection strength between the screws 222 and the second stage 221 can be enhanced.
In order to improve the levelness of the second bearing table 221 of the height adjusting mechanism 20 during the height adjustment process, in this embodiment, the height adjusting mechanism 20 further includes two support rods 223 extending from the second bearing table 221 in a direction away from the weighing table 30, the first bearing table 11 is provided with two through holes corresponding to the two support rods 223, and one ends of the two support rods 223 far away from the second bearing table 221 extend out of the first bearing table 11 through the two through holes. Like this, two via holes can play spacing direction's effect to a certain extent, prevent that actuating mechanism 21 from taking place the slope at height-adjusting in-process.
Further, in order to make the above-mentioned limiting guiding function better, in this embodiment, the device further includes two limiting cylinders 23 respectively sleeved in the two through holes, two ends of the limiting cylinder 23 respectively extend out of the first plummer 11, and the two support rods 223 respectively pass through the two limiting cylinders 23 and extend out of the limiting cylinder 23. It should be understood that the limiting cylinder 23 plays a guiding role, the inner wall of the limiting cylinder also corresponds to the slideway of the support rod 223, and a person skilled in the art can select the sleeving mode of the limiting cylinder 23 in the through hole by himself, as long as the limiting cylinder 23 is ensured not to move up and down along with the movement of the support rod 223.
In this embodiment, in order to facilitate the better matching between the liquid crystal glass substrate weighing device 100 and the production line, the liquid crystal glass substrate of the present application further includes a cart bearing table 40, the cart bearing table 40 is disposed on one side of the weighing table 30 departing from the rack 10, and the width of the cart bearing table 40 in the conveying direction of the liquid crystal glass substrate is greater than the width of the weighing table 30 in the conveying direction of the liquid crystal glass substrate. Therefore, the whole device structure can be more compact, and the liquid crystal glass substrate weighing device 100 can be suitable for more production conditions only by replacing the trolley bearing table 40 according to different production line requirements or liquid crystal glass substrate size requirements.
Illustratively, the cart bearing platform 40 includes a third bearing platform 41 and two side plates 42 extending outward from one surface of the third bearing platform 41, the third bearing platform 41 and the two side plates 42 enclose a containing cavity 43, and the cart bearing platform 40 is clamped on the weighing platform 30 through the containing cavity 43. Thus, the cart support 40 is only required to be fastened to the weighing platform 30. Preferably, the distance between the two side plates 42 should be adapted to the width of the weighing table 30 in the conveying direction of the liquid crystal glass substrate, so that the carriage 40 does not shake.
When the liquid crystal glass substrate is placed on the cart, in this embodiment, the cart bearing table 40 further includes two limiting members 44, and the two limiting members 44 are respectively disposed on one surface of the cart bearing table 40 departing from the weighing table 30, and are used for limiting the cart bearing the liquid crystal glass substrate. Therefore, the trolley can be limited by the two limiting parts 44, the trolley is prevented from moving, and the weighing precision is improved.
Another aspect of the present embodiment further provides a method for weighing a liquid crystal glass substrate, which uses the above glass substrate weighing apparatus. Since the structure and the advantages of the above-mentioned glass substrate weighing device have been explained and illustrated in detail in the foregoing, further description is omitted. The method for weighing the liquid crystal glass substrate provided by the embodiment comprises the following steps:
s1: acquiring a transmission position signal of the liquid crystal glass substrate, and adjusting the distance between the weighing platform 30 and the rack 10 according to the transmission position signal so that the weighing platform 30 jacks up the liquid crystal glass substrate;
s2: receiving a weight signal detected by a mass sensor;
s3: the weight signal is subtracted by a preset value to obtain a weight difference value.
First, the transmission position signal of the liquid crystal glass substrate is obtained, which may be a transmission position signal of the liquid crystal glass substrate obtained by a detection mechanism provided on a production line of the liquid crystal glass substrate; or a detection mechanism can be independently arranged on the liquid crystal glass substrate weighing device 100, and the transmission position of the liquid crystal glass substrate can be detected by the detection mechanism of the liquid crystal glass substrate weighing device 100; alternatively, the transfer position signal of the liquid crystal glass substrate may be acquired manually. Specifically, what kind of method is adopted to obtain the transmission position signal of the liquid crystal glass substrate, and a person skilled in the art can select the method according to actual requirements.
Secondly, the transmission position signal is a distance signal from the liquid crystal glass substrate to the weighing station. In this way, whether the liquid crystal glass substrate reaches the specified position can be judged by the transfer position signal, and the height of the weighing table 30 is adjusted according to the transfer position signal to jack up the liquid crystal glass substrate.
Thirdly, the receiving unit of the liquid crystal glass substrate weighing apparatus 100 itself may be used to receive the signal detected by the mass sensor, or the receiving unit on the production line may be used to receive the weight signal.
Fourthly, the weight difference value obtained by subtracting the preset value from the weight signal is the weight of the liquid crystal glass substrate. When the trolley bearing table 40 is not arranged and the single liquid crystal glass substrate is conveyed in the previous process of the production line, the preset value is 0; when the trolley bearing table 40 is not arranged and a trolley bearing the liquid crystal glass substrate is conveyed from a pre-production line process, the preset value is the weight of the trolley; when the trolley bearing table 40 is arranged and the single liquid crystal glass substrate is conveyed in the previous process of the production line, the preset value is the weight of the trolley bearing table 40; when the trolley bearing table 40 is arranged and a trolley bearing the liquid crystal glass substrate is conveyed from the previous process of the production line, the preset value is the sum of the weight of the trolley and the weight of the trolley bearing table 40. In addition, in order to ensure the normal operation of the mass sensor, in the present embodiment, the span of the mass sensor should be preset to 120% of the sum of the weight and the weight of the liquid crystal glass substrate.
The above description is only an alternative embodiment of the present invention and is not intended to limit the present invention, and various modifications and variations of the present invention may occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
