[0024] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0025] The upper film and tray bonding fixture includes a fixture body 1, a tray component 4, a tempered film 2, and multiple positioning pins 3. The tempered film 2 includes a film body, an upper edge sheet, and two lower edge sheets. The two ends of the film body are respectively arranged to be joined with the upper edge sheet and the lower edge sheet. The two lower edge sheets are arranged in a spaced-apart correspondence. The tray component 4 has a main tray cavity, two lower tray portions 42, and an upper tray portion 41. The main tray cavity is located between the lower tray portions 42 and the upper tray portions 41, and the lower tray portions 42 and the upper tray portions 41 are respectively adhesive. The main tray cavity is used to store the film body, the upper tray portions 41 are used to bond the upper edge sheet, and the lower tray portions 42 are used to bond the lower edge sheet. The positioning pins 3 are installed on the fixture body 1, and the positioning pins 3 are arranged to extend protrudingly in a direction away from the fixture body 1. The positioning pins 3 are used to simultaneously penetrate and position the upper edge sheet and the upper tray portion 41, or the positioning pins 3 are used to simultaneously penetrate and position the lower edge sheet and the lower tray portion 42.

[0026] When performing the bonding operation of the above-mentioned upper film and tray bonding fixture, the tempered glass film 2 is placed on the fixture body 1, and each positioning pin 3 is simultaneously inserted and positioned. The material strip is straightened and laid flat, and the positioning holes 44 of the tray part 4 are aligned with each positioning pin 3. The tray part 4 is placed face down on the fixture body 1. At this time, the upper plate part 41 and the lower plate part 42 are aligned with the upper edge piece and the lower edge piece, respectively. By gently pressing the upper plate part 41 and the lower plate part 42 by hand, the tray part 4 and the tempered glass film 2 are precisely bonded. The cost is low and the operation is convenient. Positioning before bonding improves the packaging positioning effect of the tempered glass film 2 and improves the bonding accuracy.

[0027] The tray component 4 has multiple positioning holes 44, which are used for the positioning pin 3 to pass through. In this way, the positioning pin 3 and the positioning hole 44 cooperate to achieve the positioning of the tray component 4 and improve the adhesion accuracy between the tray component 4 and the tempered glass film 2.

[0028] The fixture body 1 includes a main plate, an upper edge plate, and two lower edge plates. The two ends of the main plate are respectively connected to the upper edge plate and the two lower edge plates. Each positioning pin 3 is installed on the upper edge plate or the lower edge plate. The upper edge plate, the upper edge piece, and the upper plate 41 are arranged in sequence. The upper edge plate is used to support the upper edge piece and the upper plate 41, and the upper edge plate is used to bear the pressing force. The lower edge plate, the lower edge piece, and the lower plate 42 are arranged in sequence. The lower edge plate is used to support the lower edge piece and the lower plate 42, and the lower edge plate is used to bear the pressing force.

[0029] The upper edge plate and the two lower edge plates provide support for the upper plate 41, the lower plate 42, the upper edge piece, and the lower edge piece, facilitating the subsequent bonding of the upper plate 41 with the upper edge piece and the subsequent bonding of the lower plate 42 with the lower edge piece.

[0030] Along the length of the upper edge plate, the positioning pin 3 is installed at the end of the upper edge plate. The upper edge plate has an upper pressing area, which is used to bear the pressing force. The upper pressing area and the positioning pin 3 are arranged in sequence along the length direction. In this way, the setting of the positioning pin 3 does not affect the fit between the upper edge plate and the upper edge piece, so that the upper edge plate and the upper edge piece have a fitting space, which facilitates the fit between the upper edge plate and the upper edge piece.

[0031] Along the length of the lower edge plate, the positioning pin 3 is installed at the inner end of the lower edge plate, and the outer end of the lower edge plate forms a lower pressing area, which is used to bear the pressing force. In this way, it is convenient to apply pressing force to the two lower plate parts 42 at the same time. At the same time, the lower pressing area is located at the outer end, which helps to improve the adhesion effect. Moreover, the two positioning pins 3 arranged in this way have a better positioning effect on the tempered glass film 2.

[0032] The membrane body includes an upper mold layer and a glass layer, which are stacked together. The two ends of the upper mold layer are respectively connected to the upper edge sheet and the lower edge sheet. The cross-sectional area of ​​the upper mold layer is larger than that of the glass layer. The main tray cavity is used to store and secure the upper mold layer. In this way, the glass layer is stored and protected by the tray 4 securing it to the upper mold layer.

[0033] The main board has four clearance slots 11, which are arranged in a corresponding manner at the four corners. The clearance slots 11 are recessed in the direction away from the tray component 4. The tray component 4 has four locking parts, which are arranged in a corresponding manner at the four corners. The four locking parts are used to lock the upper mold layer, and the four locking parts are arranged in a one-to-one correspondence with the four clearance slots 11.

[0034] In this way, under the action of the four clearance slots 11, when the tray 4 is placed face down on the fixture body 1, there will be no squeezing between the main board and the tray 4, avoiding deformation of the tray 4, improving the locking effect between the tray 4 and the tempered film 2, and ensuring the packaging of the tempered film 2.

[0035] The motherboard has two side through slots 12, which are arranged at intervals along the length of the motherboard and are arranged through the entire length of the motherboard. The side extension of the glass layer is aligned or offset with the edges of the two side through slots 12. In this way, by cooperating with the two side through slots 12, the alignment of the glass layer is judged along the length of the glass layer, so as to avoid large offset of the glass layer, which would affect the packaging effect of the tempered glass film 2 and prevent the tempered glass film 2 from being damaged during transportation.

[0036] The motherboard has a top through groove 13, which is arranged in a through-hole manner and extends in a long strip along the width direction. The top edge of the glass layer is aligned with or offset from the top edge of the top through groove 13. Under the action of the top through groove 13, the alignment of the glass layer is judged along the width direction of the glass layer to avoid large offset of the glass layer, which would affect the packaging effect of the tempered film 2 and prevent the tempered film 2 from being damaged during transportation.

[0037] The pallet component 4 includes a pallet body and four pallet posts 43. The four pallet posts 43 are respectively assembled with the pallet body and form a main pallet cavity. The pallet body has a lower pallet portion 42 and an upper pallet portion 41, and the pallet posts 43 form a locking portion. Under the action of the four pallet posts 43, the tempered glass film 2 is locked.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
