Description

Technical Field

[0001] The utility model relates to the technical field of display packaging, in particular to a jig used for display packaging. Background Art

[0002] Silicon-based OLED displays have many advantages such as high resolution, high integration, low power consumption, small size and light weight. They are the core components of near-eye display systems and are widely used in AR glasses, VR helmets, infrared detectors, and 3D medical equipment, with an increasing market share.

[0003] At present, when packaging silicon-based OLED displays, it is necessary to fix smaller silicon-based OLED displays on the circuit board (PCB) with solid crystal glue. Specifically, the circuit board is placed on a carrier, and the machine automatically applies solid crystal glue to each circuit board. After applying the solid crystal glue, the printed silk screen on the circuit board is manually inspected to determine the position of the display on the circuit board to be bonded, and then the display is placed in the position to be bonded. However, there is a large error in manual visual positioning. After the circuit board and the screen body are aligned and bonded, they need to be placed under a microscope to check whether the bonding is in place. For unqualified ones, multiple fine-tuning is required, which makes the work efficiency low. After the bonding position is checked for correctness, the carrier is transferred to the baking carrier and placed in the oven to cure the solid crystal glue. However, because the glue is still fluid before curing, the display is prone to slippage during the transfer process, resulting in substandard product size.

[0004] Therefore, there is an urgent need for a jig for display packaging to solve the above technical problems. Utility Model Content

[0044] like Figures 1 to 8 As shown, the utility model provides a jig for display packaging, which can be used to package a silicon-based OLED display 100, including a baking seat 1, a first positioning plate 2 and a second positioning plate 3. The baking seat 1 is provided with at least one accommodating cavity 10, and the accommodating cavity 10 includes a first step groove 11 and a second step groove 12 arranged in sequence from bottom to top, and the bottom wall of the first step groove 11 is provided with a first through hole 13; the first positioning plate 2 is clamped in the first step groove 11; the first positioning plate 2 is provided with a plurality of positioning grooves 21 at intervals, and the positioning groove 21 is used to accommodate a circuit board 200 and define the position of the circuit board 200; the bottom wall of the positioning groove 21 is provided with a second through hole 22 connected with the first through hole 13; the second positioning plate 3 is clamped in the second step groove 12; the second positioning plate 3 is provided with a plurality of positioning holes 31 at intervals, and the plurality of positioning holes 31 are connected with the plurality of positioning grooves 21 in a one-to-one correspondence. The positioning holes 31 are used to accommodate the display 100 and define the position of the display 100, so that the display 100 is aligned with the position to be bonded of the circuit board 200.

[0045] When packaging the display 100, first clamp the first positioning plate 2 into the first step groove 11, place the circuit board 200 into the positioning groove 21, and apply glue to the position of the circuit board 200 to be bonded; then clamp the second positioning plate 3 into the second step groove 12, and place the display 100 into the positioning hole 31, so that the bottom surface of the display 100 is bonded to the position of the circuit board 200 to be bonded; then put the baking seat 1 into the oven to cure the glue, thereby realizing the packaging and fixation of the display 100 and the circuit board 200, which is convenient for personnel operation.

[0046] By providing the positioning groove 21 and the positioning hole 31, the position of the display 100 relative to the circuit board 200 can be determined, the positional accuracy of the position to be attached to the circuit board 200 can be improved, and the slippage of the display 100 during the transfer process can be avoided. The positioning hole 31 is connected to the positioning groove 21, and the display 100 can be attached to the circuit board 200 during packaging. The first positioning plate 2 and the second positioning plate 3 are both provided on the baking seat 1. The baking seat 1 can support and limit the first positioning plate 2 and the second positioning plate 3 while also serving as a baking carrier. The baking seat 1 is provided with a first through hole 13, which is connected to the second through hole 22 of the bottom wall of the positioning groove 21, so that the circuit board 200 can be better exposed to the outside, thereby improving the baking effect.

[0047] Optionally, the baking seat 1 is provided with a receiving cavity 10 for easy processing. Alternatively, the baking seat 1 is provided with multiple receiving cavities 10, which are evenly spaced and distributed to improve packaging efficiency.

[0048] Optionally, the bottom surface of the second positioning plate 3 is aligned with the top surface of the first positioning plate 2, and the opening of the positioning hole 31 on the side closest to the first positioning plate 2 is coplanar with the notch of the positioning slot 21. This arrangement allows the entire display 100 to be positioned within the positioning hole 31, effectively securing the display 100. Alternatively, the bottom surface of the second positioning plate 3 can be spaced apart from the top surface of the first positioning plate 2, with part of the display 100 positioned within the positioning hole 31 and part of the display 100 positioned in the gap between the second positioning plate 3 and the first positioning plate 2, so that the positioning function is achieved.

[0049] Optionally, in one embodiment, as Figure 3 As shown, the position of the circuit board 200 is limited only by the positioning groove 21. Alternatively, in another embodiment, as shown in FIG. Figure 4 and Figure 5 As shown, the inner sidewall of the positioning groove 21 is recessed with an abutment groove 23. The jig for display packaging includes an elastic component 4, which is disposed within the abutment groove 23. The elastic component 4 is used to press the circuit board 200 against the inner sidewall of the positioning groove 21 away from the elastic component 4. By providing the elastic component 4, the circuit board 200 is pressed against the inner sidewall of the positioning groove 21 away from the elastic component 4, making positioning more precise.

[0050] Specifically, the elastic assembly 4 includes a fixed member 41, an elastic member 42, and a sliding member 43. The fixed member 41 is detachably connected to the abutment groove 23, and the sliding member 43 is slidably connected to the abutment groove 23. The fixed member 41 is provided with a first guide groove 411, and the sliding member 43 is provided with a second guide groove 431. The elastic member 42 is disposed between the fixed member 41 and the sliding member 43, with its ends slidably connected to the first guide groove 411 and the second guide groove 431, respectively. The elastic member 42 is used to press the sliding member 43 against the circuit board 200. The provision of the sliding member 43 prevents direct contact between the elastic member 42 and the circuit board 200, which could damage the circuit board 200. The provision of the first guide groove 411 and the second guide groove 431 serves to guide the elastic member 42. When the elastic member 42 presses the circuit board 200 against the inner wall of the positioning groove 21 on the side away from the elastic assembly 4, the circuit board 200 can be precisely aligned with the inner wall. The fixing member 41 is detachably connected to the abutting groove 23, and the first guide groove 411 is provided on the fixing member 41, which is convenient for processing and assembly and disassembly. Specifically, the elastic member 42 is a spring.

[0051] Alternatively, as Figure 6 As shown, multiple engaging portions 32 are spaced apart on the outer periphery of the bottom of the second positioning plate 3. These engaging portions 32 enclose a positioning cavity, and the outer wall of the first positioning plate 2 engages with the positioning cavity. While the second stepped groove 12 engages with the second positioning plate 3 to restrict the position of the second positioning plate 3, the outer wall of the first positioning plate 2 engages with the positioning cavity at the bottom of the second positioning plate 3 to further restrict the position of the second positioning plate 3, ensuring the precise position of the positioning hole 31 relative to the positioning groove 21 and securely fixing the second positioning plate 3.

[0052] Optionally, the jig for display packaging includes a pressing member 5, which is fixed to the baking seat 1 and is used to abut against the top surface of the second positioning plate 3. By providing the pressing member 5, the first positioning plate 2 and the second positioning plate 3 are further prevented from moving during the process of transferring the baking seat 1 to the oven. Specifically, two pressing members 5 are correspondingly provided outside each accommodating cavity 10, and the two pressing members 5 are diagonally arranged. The above arrangement has a better pressing effect on the second positioning plate 3 and saves material cost and installation cost. Optionally, the pressing member 5 is a pressing spring. The pressing spring has an elastic effect, which can press the second positioning plate 3 while facilitating the removal of the second positioning plate 3 from the second step groove 12.

[0053] Optionally, one of the inner wall of the second step groove 12 and the second positioning plate 3 is provided with a first fool-proof protrusion 14, and the other is provided with a first fool-proof groove 33, and the first fool-proof protrusion 14 is engaged with the first fool-proof groove 33. In one embodiment, Figure 2 and Figure 7As shown, the inner wall of the second step groove 12 is provided with a first foolproof protrusion 14, and the second positioning plate 3 is recessed with a first foolproof groove 33. The first foolproof protrusion 14 is engaged with the first foolproof groove 33. The first foolproof groove 33 and the first foolproof protrusion 14 prevent the operator from placing the second positioning plate 3 upside down.

[0054] In addition, a second fool-proofing protrusion may be provided on one of the inner wall of the first step groove 11 and the first positioning plate 2, and a second fool-proofing groove may be provided on the other. The second fool-proofing protrusion and the second fool-proofing groove may be engaged with each other to prevent the operator from placing the first positioning plate 2 upside down.

[0055] Alternatively, as Figure 7 and Figure 8 As shown, the inner sidewalls of the positioning groove 21 and the inner sidewalls of the positioning hole 31 are recessed with a plurality of first avoidance grooves 6 to avoid damage to the circuit board 200 and the display 100 during installation or removal. Figure 1 As shown, the inner wall of the accommodating cavity 10 is recessed with a plurality of second avoidance grooves 15 at intervals, so that a person can conveniently pass through the second avoidance grooves 15 to install and remove the first positioning plate 2 and the second positioning plate 3. Figure 2 As shown, the inner side walls of the first step groove 11 and the inner side walls of the second step groove 12 are both recessed with a plurality of third avoidance grooves 16 to avoid damage to the first positioning plate 2 and the second positioning plate 3 during installation or removal of the first positioning plate 2 and the second positioning plate 3.

[0056] Optionally, the baking seat 1 is provided with a handle 17 to facilitate an operator to move the baking seat 1 .
