[0002] In the existing automotive screen bonding technology, the combination of display glass (TP glass) and liquid crystal module includes full bonding and frame bonding. Among them, the frame bonding combination often uses foam double-sided adhesive material, which requires the TP glass and foam double-sided adhesive to be attached.

[0003] See also Figure 1 and Figure 2 In the prior art, a laminating jig 3 is often used when adhering the display glass 1 to the foam 2. During the laminating process, the laminating jig 3 is at the bottom, the foam 2 is placed on the laminating jig 3, and the display glass 1 is at the top. The display glass 1 moves from top to bottom and is attached to the foam 2 to form a component. After the laminating is completed, the component is removed from the laminating jig 3. An FPC 4 is provided on the lower side of the TP glass, and a corresponding air avoidance groove 6 is provided on the jig 3, so that when the FPC 4 is conveniently pasted, it can pass through the air avoidance groove 6 without affecting the attachment of the display glass 1 to the foam 2. However, the plug-in end of the FPC 4 on the lower side of some TP glasses is provided with a bendable reinforcement plate 5. When the component is removed from the laminating jig 3, the bendable reinforcement plate 5 is easily unfolded, resulting in the inability to pass through the air avoidance groove 6 smoothly, causing the FPC to be blocked and damaged. In view of this, if the air avoidance groove 6 is opened larger, it is easy to cause the foam to be stuck in the groove and affect the frame assembly. Utility Model Content

[0031] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0032] Example 1

[0033] See also Figure 3 and Figure 4 The frame-mounted foam jig of this embodiment includes a base 7, a foam placement groove 71 is provided on the base 7, and a void avoidance portion is provided on the foam placement groove 71. The structure of the void avoidance portion is as follows:

[0034] It includes a stopper 8 arranged on the lower surface of the base 7, the stopper 8 extends downward from the lower surface of the base 7, and the extending direction is the height direction of the stopper 8;

[0035] At least one positioning hole 73 is provided in the stopper 8, which is used to pass the FPC 4 with the bent reinforcing plate 5 at the bottom of the display glass 1. The height direction of the positioning hole 73 is consistent with the height direction of the stopper 8. The two end openings of the positioning hole 73 in the height direction are respectively located on the upper surface of the foam placement groove 71 and the bottom surface of the stopper 8;

[0036] like Figure 3 As shown, the height L of the stopper 8 is set as follows: when the bottom surface of the display screen glass 1 is bonded with the foam 2 placed in the foam placement groove 71, at least a portion of the reinforcing plate 5 on the FPC 4 does not extend out of the stopper 8, that is, the reinforcing plate 5 does not extend out at all, or only a portion of the tail extends out of the stopper 8, thereby preventing the bent reinforcing plate 5 from extending out of the stopper completely, and then stretching out, so that when it is removed after bonding, the reinforcing plate 5 is interfered by the fixture and causes damage to the FPC.

[0037] As a specific implementation, the cross section of the positioning hole 73 is a long waist hole shape.

[0038] As a specific implementation, support feet 9 are provided on the lower surface of the base 7 .

[0039] As a specific implementation, the height of the supporting foot 9 is greater than the height of the stopper 8 .

[0040] As a specific implementation, the air avoidance portion is located close to one side of the long side of the foam placement groove 71 .

[0041] As a specific implementation, the reinforcing plate 5 is located at one end close to the rear of the FPC 4 .

[0042] As a specific implementation, the reinforcing plate 5 is made of PLA.

[0043] Combination Figure 1 and Figure 2 The workflow of this embodiment includes the following steps:

[0044] 1. Place the foam 2 in the foam placement groove 71 of the jig for automatic positioning;

[0045] 2. When attaching, bend the FPC 4 at the bottom of the display glass 1 90° relative to the glass. After bending, the FPC 4 is perpendicular to the display glass 1. Figure 1 The status shown;

[0046] 3. Move the display screen glass 1 downward so that the bent FPC 4 passes downward through the foam 2 and the positioning hole 73. Since the height L of the stopper 8 is sufficient, the FPC 4 and the reinforcing plate 5 are both limited in the positioning hole 73 during the entire bonding process. Therefore, when the bonding is completed and the glass is removed, the reinforcing plate 5 will not unfold and cause interference, thereby preventing the FPC 4 from being stuck.

[0047] As a preferred embodiment, at least two positioning holes 73 are provided, and at least two positioning holes 73 are arranged in parallel and spaced apart.

[0048] As a preferred embodiment, at least two positioning holes 73 are arranged at equal intervals.

[0049] This embodiment is specifically provided with five positioning holes 73. When placing the display screen glass 1, the FPC 4 can pass through any positioning hole 73. When taking it, the reinforcing plate of the FPC will not be interfered, making it easy to take and place the PFC and avoiding damage.

[0050] Example 2

[0051] See also Figure 5 The frame-mounted foam jig of this embodiment is different from that of Embodiment 1 in that:

[0052] The structure of the air avoidance portion also includes a positioning groove 72 arranged in the foam placement groove 71 and corresponding to the block 8 above and below. The bottom surface of the positioning groove 72 is lower than the upper surface of the foam placement groove 71; the upper end opening of the positioning hole 73 in the height direction is correspondingly located at the bottom surface of the positioning groove 72.

[0053] Compared with Embodiment 1, Embodiment 2 has a positioning groove 72 added to the upper surface of the foam placement groove 71, and the top of each positioning hole 73 is correspondingly located at the bottom surface of the positioning groove 72. The positioning groove 72 makes it easier for the FPC 4 to pass through the foam 2 and the positioning holes 73 after being bent downward.
