[0021] To provide a better understanding of the purpose, structure, features and functions of this utility model, detailed descriptions are provided below with reference to the embodiments.

[0022] Reference Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a pressure-holding fixture according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the combination of the upper cover plate and the adhesive strip according to an embodiment of the present invention. The present invention provides a pressure-holding fixture 100 for the adhesive curing of a pressure-holding product 101. The pressure-holding fixture 100 includes an upper cover plate 11, an adhesive strip 12, and a lower cover plate 13. The upper cover plate 11 has an inner surface 111 and a groove 112. The inner surface 111 is recessed to form the groove 112, which has a first long groove 1121, a first short groove 1122, a second long groove 1123, and a second short groove 1124. The long groove 1123 and the second short groove 1124 are sequentially connected to form a rectangle; the adhesive strip 12 is disposed in the recess 112, and at least a portion of the recess 112 is not covered by the adhesive strip 12 to form a first notch 121, which serves as a vent; the lower cover plate 13 has a receiving groove 131 for receiving the product 101; wherein, the product 101 is placed in the receiving groove 131, and the inner surface 111 of the upper cover plate 11 covers the receiving groove 131 of the lower cover plate 13 so that the adhesive strip 12 presses the product 101. In this way, the gap generated after assembly can be reduced by the adhesive strip with vent embedded in the upper cover and in conjunction with the lower cover to meet the high requirements of pressure holding after dispensing.

[0023] Reference Figure 1 and Figure 2 As shown, the upper cover plate 11 is plate-shaped and has an inner surface 111 and a groove 112. When the upper cover plate 11 presses against the product 101, the inner surface 111 faces the product 101. The groove 112 has a first long groove 1121, a first short groove 1122, a second long groove 1123, and a second short groove 1124 that are connected at their ends. The first long groove 1121 and the second long groove 1123 correspond to the long side of the upper cover plate 11, and the first short groove 1122 and the second short groove 1124 correspond to the short side of the upper cover plate 11. The groove 112 is used to accommodate the adhesive strip 12, which protrudes slightly from the inner surface 111. In this way, the upper cover plate 11 presses against the product 101 and, together with the adhesive strip 12 in the groove 112, presses against the edges of the upper surface of the product 101, achieving uniform force distribution around the product's perimeter.

[0024] Reference Figure 1 and Figure 2 As shown, the rubber strip 12 can be made of rubber, and the diameter of the rubber strip 12 is slightly larger than the groove diameter of the groove 112, so that the rubber strip 12 is tightly embedded in the groove 112. The rubber strip 12 is embedded in the groove 112 and forms a first notch 121. The first notch 121 is located at the first elongated groove 1121 of the groove 112. The first notch 121 acts as an air vent to prevent the rubber strip 12 from being completely sealed with the product 101, thus preventing the rubber strip 12 from adhering to the upper surface of the product 101. It should be noted that the formation of the first notch 121 may be based on the fact that the length of the rubber strip 12 cannot fill the groove, resulting in a part of the groove 121 not being provided with the rubber strip 12, thus forming a notch. This is easily understood in the industry and will not be elaborated further.

[0025] Reference Figure 1 and Figure 2 As shown, the lower cover plate 13 has a receiving groove 131 for receiving the product 101. The lower cover plate 13 is plate-shaped. After the product 101 is placed in the receiving groove 131 of the lower cover plate 13, the upper cover plate 11 is placed on the lower cover plate 13 so that the adhesive strip 12 presses down on the product 101.

[0026] Reference Figure 1 and Figure 2 As shown, the pressure-holding fixture 100 also includes a first positioning post 141 and a second positioning post 142. The first positioning post 141 and the second positioning post 142 are disposed on the lower cover plate 13. The upper cover plate 11 has a first positioning hole 1131 and a second positioning hole 1132. The first positioning hole 1131 and the second positioning hole 1132 are located around the groove 112. When the upper cover plate 11 covers the lower cover plate 13, the first positioning post 141 passes through the first positioning hole 1131 and the second positioning post 142 passes through the second positioning hole 1132, causing the adhesive strip 12 to press the product 101. In specific implementation, the first positioning post 141 and the second positioning post 142 are respectively located on the diagonals of the lower cover plate 13. After product 101 is placed in the receiving slot 131 of the lower cover plate 13, the operator aligns the first positioning hole 1131 of the upper cover plate 11 with the first positioning post 141 on the upper left of the lower cover plate 13. The first positioning post 141 passes through the first positioning hole 1131. The operator then aligns the second positioning post 1132 of the upper cover plate 11 with the second positioning post 142 on the lower right of the lower cover plate 13. The second positioning post 142 passes through the second positioning hole 1132. The heights of the first positioning post 141 and the second positioning post 142 are both less than the thickness of the upper cover plate 11 to avoid the positioning posts protruding from the upper cover plate 11 and interfering with the pressure holding fixture 100 when it is placed in the pressurizing equipment.

[0027] Reference Figure 1 and Figure 2As shown, the pressure-holding fixture 100 also includes a first opening groove 151, which is located on one side of the lower cover plate 13. The first opening groove 151 is connected to the receiving groove 131. The upper cover plate 11 is separated from the lower cover plate 13 through the first opening groove 151, and the product 101 is taken out from the receiving groove 131 through the first opening groove 141. In a specific implementation, the pressure-holding fixture 100 also includes a second opening groove 152, which is located on the other side of the lower cover plate 13. The second opening groove 152 is connected to the receiving groove 131. The operator uses the first opening groove 151 and the second opening groove 152 to separate the upper cover plate 11 from the lower cover plate 13, the first positioning post 141 is disengaged from the first positioning hole 1131, and the second positioning post 142 is disengaged from the second positioning hole 1132. The operator uses the first opening groove 151 and the second opening groove 152 to take out the product 101 with the cured adhesive from the receiving groove 131.

[0028] In this embodiment of the invention, the adhesive strip 12 presses against the edge of the product 101. Specifically, when the upper cover plate 11 covers the lower cover plate 13, the vertical projection of the groove 112 onto the receiving groove 131 is located within the receiving groove 131. In this way, a uniform force is applied to the edge of the upper surface of the product 101, so that the product 101 can be better cured.

[0029] Refer to together Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of a pressure-holding fixture according to another embodiment of the present invention. Figure 4 This is a schematic diagram of the combination of the top cover plate and the adhesive strip according to another embodiment of the present invention. The only difference between the pressure holding fixture 100' and the pressure holding fixture 100 is that the adhesive strip 12' has an additional notch compared to the adhesive strip 12. The rest will not be described in detail. The adhesive strip 12' is embedded in the groove 112 and forms a second notch 122. The second notch 122 is located at the first elongated groove 1121 of the groove 112. The first notch 121 and the second notch 122 serve as two air holes to meet the pressure requirements for pressing and solidifying the adhesive on the upper side of the product 101. In specific implementation, the first elongated groove 1121 has a vertical line A. The first notch 121 and the second notch 122 are located on both sides of the vertical line A, and the two air holes are located at both ends of the first elongated groove 1121 to achieve better pressure and solidification of the product 101.

[0030] In this embodiment of the invention, the first notch 121 has a first spacing D1 when projected perpendicularly onto the inner surface 111, and the second notch 122 has a second spacing D2 when projected perpendicularly onto the inner surface 111. The first spacing D1 is smaller than the second spacing D2. In specific implementation, the pore size formed by the first notch 121 in the first long groove 1121 is smaller than the pore size formed by the second notch 121 in the first long groove 1122. This asymmetrical pore size is more conducive to airflow exhaust.

[0031] In summary, the pressure-holding fixture provided by this utility model is used for pressurizing adhesive curing of products. The fixture includes an upper cover plate, an adhesive strip, and a lower cover plate. The upper cover plate has an inner surface and a groove. The inner surface is recessed to form the groove, which has a first long groove, a first short groove, a second long groove, and a second short groove connected in sequence. The first long groove, the first short groove, the second long groove, and the second short groove are connected to form a rectangle. The adhesive strip is disposed in the groove, and at least a portion of the groove is not covered by the adhesive strip to form a first notch, serving as a vent. The lower cover plate has a receiving groove for accommodating the product. The product is placed in the receiving groove, and the inner surface of the upper cover plate covers the receiving groove of the lower cover plate, causing the adhesive strip to press the product. Thus, by using the adhesive strip with vents embedded in the upper cover and working in conjunction with the lower cover, the gaps generated after assembly can be reduced to meet the high requirements of pressure holding after dispensing.
