Description

[0002] Smart display production lines are usually automated production lines that use automatic material feeding to feed various parts and auxiliary materials; however, the display imaging of smart displays such as LCD and OLED requires the use of polarizers, and the front and rear sides of the panel glass need to be attached with polarizers respectively. Therefore, a polarizer feeding bin is required in the production line of smart displays such as LCD and OLED to meet the feeding needs of the production line for attaching polarizers. The production line in the prior art usually uses Figures 1 to 4 The vertical feeding polarizer supply bin shown in the figure feeds materials by vertical lifting. The polarizers in the bin 100 are stacked in the vertical direction. The vertical feeding polarizer supply bin needs to feed and store materials from top to bottom, and the materials also need to be taken from top to bottom. When replenishing and adding materials, the production line needs to be shut down before the feeding operation can be carried out, which increases energy consumption and reduces production efficiency; and the production line also takes materials from top to top when using the vertical feeding polarizer supply bin to take materials; when replenishing and adding materials, the vertical feeding polarizer supply bin needs to retain a certain amount of materials to prevent the complete production function of the production line from being affected when the material supply is completely cut off. Therefore, it is necessary to add materials in advance when the materials are not completely used up and there is a certain amount of inventory, which causes the materials at the bottom of the material bin to be piled up for a long time and not used, which is easy to deteriorate and fail, increasing cost investment, and easily affecting product quality after being mistakenly flowed to the production line.

[0056] The horizontal material taking mechanism and the material pressing mechanism are adopted, and the material is fed from the back side of all the polarizers in the material box. The polarizers can be taken out in sequence according to the feeding order. There is no need to stop the machine when adding materials. The operation is convenient, cost investment is saved, production efficiency is improved, and it is safe and reliable. The last-in-front-out method is adopted to realize the first-in-first-out order of the polarizers in the polarizer material bin, which can ensure that all the polarizers in the material bin can be used without accumulation, deterioration and failure.

[0058] The first technical solution of the first embodiment of the present invention provides a detailed technical structure of a polarizer feeding bin device for an intelligent display production line. The specific structure of the material box of the first embodiment is as follows:

[0059] The material box 1 is composed of a base 11, a first end plate 12 and a horizontal L-shaped enclosure 13. The L-shaped enclosure is composed of a rear side plate 131 and a second end plate 132 fixedly connected. The enclosure 13 and the first end plate 12 enclose the space above the base 11 to form a feeding bin space with an open top and a front opening. The structure is simple and compact, the number of parts is small, and the process is simple.

[0060] The main structures of the pressing mechanism 3 are a pressing plate 31 and a pressing cylinder 32. A first guide groove 121 is set on the first end plate 12. The pressing plate 31 is slidably installed in the inner cavity of the material box 1 through a pressing slider 34 and a pressing rail 35, and the end of the pressing plate 31 extends to the outside of the first end plate 12. The pressing cylinder 32 is connected to the outer end of the pressing plate 31. The pressing plate 31 can be driven by the pressing cylinder 32 to move straight forward and backward along the first guide groove 121.

[0061] A second guide groove 133 is provided on the rear side plate 131 of the enclosure 13, and the rear end of the first end plate 12 is also slidably mounted on the rear side plate 131 through the second guide groove 133, and the first adjusting knob 122 is connected to the rear end of the first end plate 12 to form a first adjusting mechanism. The first adjusting mechanism can drive the first end plate 12 to slide along the second guide groove 133 to adjust the size of the feed bin space; the first adjusting mechanism formed by the first adjusting knob 122 can directly adopt the conventional structure in the prior art.

[0062] During actual operation, the first end plate 12 of this example adopts a horizontal U-shaped structure with an open groove in the middle. The open groove in the middle directly constitutes the first guide groove and is convenient for assembly and installation with the pressure plate; the pressure plate 31 adopts a structure with two parallel long grooves in the middle. The upper and lower sides of the horizontal U-shaped structure of the first end plate pass through the two parallel long grooves respectively. The two parallel long grooves constitute a double guide groove structure, that is, the second guide groove is a double guide groove structure.

[0063] Furthermore, the specific structure of the base 11 is composed of a bottom plate 111 and a lower bracket 112. The bottom plate 111 is supported and installed on the support plate 300 of the production line equipment through the lower bracket 112. The space above the bottom plate 111 is surrounded by the enclosure 13 and the first end plate 12 to form a feed bin space with an open top and an open front side. The production process is simple, the cost is low, and the structure is simple and compact.

[0064] A slide rail 14 and a slider 15 are provided between the bottom plate 111 and the lower bracket 112, and are connected to a second adjustment knob 16 to form a second adjustment mechanism, through which the position of the material box can be adjusted to meet the position accuracy requirements of the material taking station of the production line. The slide rail, the slider and the second adjustment knob between the bottom plate 111 and the lower bracket 112 can directly adopt conventional adjustment structures in the prior art, for example, by driving the slider of the bottom plate to move along the slide rail to adjust the position through a lead screw and a nut.

[0066] In order to ensure that only one polarizer is taken out when taking out materials and prevent joint material, a material separation sheet 4 can be provided on the side walls at both ends of the feed port. When the material taking mechanism takes out the first polarizer in the front of the material box from the discharge port at the front side of the material box, all polarizers after the first polarizer can be separated and blocked in the feed bin. The material separation sheet 4 can directly adopt the anti-joint material separation structure in the prior art, such as a flexible rubber baffle, etc.

[0067] In order to meet the use requirements of production lines with different layout structures, a second feed port can also be provided on the second end plate 132 of the material box, so as to meet the use requirements of feeding from the top and the end. In this example, the second end plate 132 can also adopt a U-shaped structure with an open groove in the middle and an open upper end, and the open upper end groove constitutes the second feed port.

[0068] As a sustainable improvement structural design scheme, the specific structure of the lower bracket 112 is provided with a horizontal support seat 113 and a vertical support slide 114, and the support seat 113 and the support slide 114 are fixedly connected to form an inverted L-shaped lower bracket; the base plate 111 is adjustably mounted on the support seat 113 through a second adjustment mechanism; the support slide 114 is slidably mounted on the support plate 300 of the production line equipment through a slide rail, and the support slide 114 is connected to a material box stepping cylinder 17, constituting a third adjustment mechanism, and the position of the material box can also be adjusted through the third adjustment mechanism. The third adjustment mechanism in this example mainly serves as a preset mechanism for subsequent alternative technical solutions.

[0069] All technical solutions in the present invention add polarizers in batches into the material box from the feed port through manual operation, and can also be used in conjunction with other automatic feeding devices when necessary. The structural solution of the upper feed port and the end feed port is more conducive to diverse adaptation.
