Embodiment 1

[0056] Such as Figure 4 As shown, this embodiment provides a pressing device, including a pressing head 10 and a driving mechanism 20 capable of driving the pressing head 10 to move, so that the pressing head 10 can move to the position where the object to be pressed needs to be pressed. Among them, the pressing device can be used in many welding fields, and this embodiment is used to illustrate the application of the pressing device to the welding of the mask 100 . The pressing head 10 mainly presses the mask 100 on the frame 200 connected thereto, and then uses the welding device 300 to perform welding.

[0057] Specifically, such as Figure 5 and 6 As shown, the compression head 10 includes a mounting frame 11, and the mounting frame 11 is provided with a through hole 12 for the welding beam 310 to pass through; The elastic claws can contact the mask 100 and press it elastically. After the elastic claws press the mask 100 and the frame 200 tightly, the welding beam 310...

Embodiment 2

[0067] Such as Figure 10 As shown, the structure of the compression head 10 in this embodiment is basically the same as that in Embodiment 1, the difference between the two is that the elastic claws of the compression head 10 in this embodiment are made of heat-resistant rubber 15, The heat-resistant rubber 15 itself has a certain degree of compressibility, and it can be directly snapped into the installation groove of the installation frame 11 , and there is no need to reserve a space 14 between the installation frame 11 and the installation frame 11 . Wherein the heat-resistant rubber 15 can be selected from nitrile rubber, fluorine rubber and the like.

Abstract

The invention discloses a pressing head and a pressing device, and belongs to the technical field of welding. The pressing head comprises a mounting frame, wherein a through hole for a welding beam topenetrate through is formed in the mounting frame. Elastic pressing claws are arranged on two sides of the through hole, are connected with the mounting frame and are capable of making contact with ato-be-pressed piece and elastically pressing the to-be-pressed piece. The pressing device comprises the pressing head. By arranging the pressing head, stress change of the to-be-pressed part cannot be transmitted to a stretching device in the welding process, so that the phenomenon that a mask plate is scrapped due to movement of patterns on the surface of a mask is avoided, and the elastic pressing claws of the pressing head can enable the mask to be tightly attached to a frame with the uneven surface, so that a problem that the mask and the frame are not welded firmly or insufficient welding exists as a molten metal liquid flows in the frame with the uneven surface is solved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a pressing head and a pressing device. Background technique [0002] Currently, in the process of manufacturing the organic light-emitting layer of an OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display screen, a mask with a pattern is used to form a required pattern on an evaporation substrate by vacuum evaporation. The mask plate includes a mask and a frame. When the mask is combined with the frame, a stretching device is used to tension the mask on the frame, and then the mask is welded on the frame by a laser to form the required mask plate. [0003] Among them, such as figure 1 and 2 As shown, after the mask 100' is tensioned by the stretching device 400', the mask 100' and the frame are melted and welded at high temperature by a laser 300'. The inventor found in the process of connecting the mask 100' to the frame 200' that: [0004] 1) When the m...
