Problems solved by technology

[0008] First: It involves a variety of production equipment, and the overall equipment structure is complex;
[0009] Second: due to the small size of the PS, PS is only provided at a fixed position on the substrate 1, and most of the formed PS photolithographic coating layer 2 is wasted, resulting in a large amount of waste of PS photosensitive materials;
[0010] Third: A large amount of PS photosensitive material needs to be removed by developing, which increases the burden on the developing equipment and consumes the developer, and the removal of a large amount of PS photosensitive material will easily cause the filter of the developing equipment to be blocked;
[0011] Fourth: There are many and cumbersome production steps, resulting in low production efficiency, high equipment and consumable costs, and low economic benefits

Embodiment 1

[0045] Such as figure 2 As shown, the spacer production equipment of this embodiment includes a raw material chamber 11 and several printing heads 12 communicating with the raw material chamber. In this embodiment, the number of printing heads 12 is 6, and the spacer raw material 14 is received from the raw material cavity 11 and output to the designated position of the spacer distribution on the substrate; in the specific implementation process, The number of the printing heads 12 can be adjusted as required, and the distance between adjacent printing heads can be adjusted, so that the spacers can be fabricated at preset positions on the color filter substrate or the array substrate.

[0046] Using the spacer production equipment described in this embodiment, the production of spacers has the advantages of less consumption of spacer raw materials, fewer and simple production steps, less equipment and other consumables involved, and thus has the advantages of simple implement...

Embodiment 2

[0053] Such as image 3 As shown, the spacer production equipment of this embodiment includes a raw material chamber 21 and the printing head 22 connected with the raw material chamber, and the printing head 22 is connected with the raw material chamber 21 through a transmission pipe 25 . The printing head 22 receives the spacer raw material 24 from the raw material chamber 21 and outputs it to a designated position to form a spacer;

[0054] The transfer pipe 25 can be a rigid pipe such as a steel pipe or a flexible pipe such as a plastic pipe. When the raw material chamber 21 is large and filled with spacer raw materials, moving the raw material 21 and the printing head 22 at the same time consumes a lot of energy and is difficult. and when the printing head 22 is connected to the raw material chamber 21 by a flexible pipe, at first the printing head 22 can be moved to make spacers in different positions, so that it is convenient to move. Again, if the printing head 22 is di...

Embodiment 3

[0057] In this embodiment, a further improvement is made on any one of the technical solutions in the first embodiment or the second embodiment. In this embodiment, the spacer manufacturing equipment further includes a flow controller. The output volume of each septum material is controlled through the setting of the flow controller, so that the control is more convenient; the flow controller can be a flow control valve; the type of the valve can be a mechanical valve, an electromagnetic valve, and the like.

[0058] The setting position of the flow control valve can be inside the printing head, the connection between the printing head and the raw material cavity; when the printing head and the raw material cavity are connected through the transmission tube, it can also be set on the transmission tube. Through the setting of the flow controller, the amount of raw material output by each printing head is controlled, so as to ensure that the raw material is not wasted, and at the...

Description

technical field [0001] The invention relates to the fields of machinery and display, in particular to a spacer manufacturing device and a manufacturing method. Background technique [0002] For a cell-type display device such as a liquid crystal display device, the spacer PS is mainly used to support the cell substrate and maintain the cell thickness. The manufacturing method of existing spacer comprises the following steps: [0003] Step 1: If figure 1 As shown, the PS photosensitive material is uniformly coated on the entire substrate 1 to form a PS photolithography coating layer 2 by using a coating device 3; [0004] Step 2: using a mask plate Mask to cover the PS photolithography coating layer 2; and exposing the PS photolithography coating layer 2 in the blank space of the Mask; [0005] Step 3: forming PS by developing; [0006] Step 4: Bake and cure PS. [0007] The above steps have the following problems: [0008] First: It involves a variety of production equ...
