Description

Technical Field

[0001] The present application relates to the field of lamination technology, and in particular to a pressing jig and assembly equipment. Background Art

[0002] With the development of full-bonding technology, manual assembly methods are no longer able to meet production requirements. To improve processing efficiency, related pressing and assembly equipment includes a carrier and a pressing component. The pressing component presses the screen and substrate carried by the carrier together, allowing the screen and substrate to be automatically bonded. Furthermore, the related pressing and assembly equipment can also achieve automatic bonding of multiple screens, facilitating the simultaneous bonding of multiple screens.

[0003] However, related press-fit assembly equipment still faces the following challenges: When laminating irregularly shaped workpieces, it is difficult to simultaneously attach multiple screens to a substrate. Specifically, when attaching irregularly shaped substrates, the screens may not be aligned and / or may be tilted relative to each other, resulting in single-sided processing. This can lead to longer processing cycles and reduced efficiency. Summary of the Invention

[0004] Based on this, it is necessary to provide a pressing fixture and assembly equipment to address the cumbersome problem of fitting special-shaped workpieces.

[0005] In a first aspect, the present application provides a pressing jig, comprising:

[0006] The lower mold includes two oppositely disposed loading parts, each loading part includes an upper surface with a receiving groove formed thereon, the bottom surfaces of the receiving grooves of the two loading parts being relatively inclined, the bottoms of the receiving grooves being provided with positioning grooves for embedding the screen, the receiving grooves of the two loading parts being interconnected to form a receiving portion for embedding the substrate; and

[0007] The upper die includes a pressing head, which includes two pressing surfaces that are relatively inclined and are pressed and matched with the receiving groove.

[0008] In the above-described embodiment, the laminating jig has two receiving grooves for receiving substrates. The bottom surfaces of the two grooves are inclined relative to each other, allowing the two grooves to mate with the bent substrate, allowing the substrate to contact the screen held within the positioning grooves within the grooves. By closing the upper and lower molds, the substrate and multiple screens can be bonded together, allowing multiple screens to be bonded to a single substrate at once, shortening the manufacturing cycle and improving work efficiency.

[0009] In one embodiment, the relative inclination angle of the two pressing surfaces is consistent with the relative inclination angle of the bottom surfaces of the two receiving grooves.

[0010] In one embodiment, the upper surface includes a fitting surface and a yielding surface, the two fitting surfaces are arranged to be inclined relative to each other, and the relative inclination angle of the two fitting surfaces is consistent with the relative inclination angle of the bottom surfaces of the two grooves, and the yielding surface is deflected toward the bottom surface of the lower mold relative to the fitting surface.

[0011] In one embodiment, the orthographic projection of the fitting surface covers the positioning groove.

[0012] In one embodiment, the two upper surfaces are arranged to be inclined relative to each other, and the relative inclination angle of the two upper surfaces is consistent with the inclination angle of the bottom surfaces of the two containing grooves;

[0013] A step surface is provided on the periphery of the pressing surface, and the step surface is press-fitted with the upper surface.

[0014] In one embodiment, the two loading portions are spaced apart, and a first avoidance portion is formed between the two loading portions.

[0015] In one embodiment, a second avoidance portion is provided on the pressure head corresponding to the first avoidance portion. When the pressure head is pressed against the material loading portion, the first avoidance portion and the second avoidance portion are correspondingly assembled to form an avoidance channel.

[0016] In the pressing jig in the above embodiment, the substrate is located in the avoidance channel as a curved portion. During the pressing process, the stress is concentrated on the curved portion of the substrate. The curved portion of the substrate deforms in the avoidance channel, which can avoid interference with the upper and lower molds when the curved portion deforms, thereby ensuring the position accuracy of the bonding surface.

[0017] In one embodiment, a gripping portion is provided on the circumference of the receiving portion, and the gripping portion is communicated with the receiving groove.

[0018] In one embodiment, the lower mold further includes a bottom surface, and an air hole is opened on the bottom of the positioning groove, and the air hole passes through to the bottom surface.

Therefore, the beneficial effects that can be achieved by the assembly equipment in this application are the same as the beneficial effects that can be achieved by the pressing jig provided in the above-mentioned embodiments, and will not be repeated here.

[0054] Reference Figure 1 , Figure 1 Exploded schematic diagram of a pressing jig provided for some embodiments of the present application. In some embodiments of the present application, a pressing jig is provided, comprising a lower mold 100 and an upper mold 200, with the lower mold 100 and the upper mold 200 being arranged correspondingly. The lower mold 100 is used to receive the screen and substrate 31, with the substrate 31 and the screen being sequentially loaded on the lower mold 100 from top to bottom. The upper mold 200 is used to press the screen and substrate 31 together to form a whole. The upper mold 200 is pressed onto the substrate 31, so that the screen and substrate 31 are in contact with each other.

[0055] Reference Figure 2 , Figure 2An exploded schematic diagram of a workpiece within a lamination jig provided in some embodiments of the present application. In this embodiment, the workpiece to be processed includes a substrate 31 and a screen, which are bonded to each other. The substrate 31 includes a first bonding block 311 and a second bonding block 312, which are tilted relative to each other, forming a curved substrate 31. The screen includes a first screen 32 and a second screen 33, which are bonded to the first bonding block 311 and the second bonding block 312 in a one-to-one correspondence.

[0056] Specifically, if Figure 1 As shown, combined with Figure 3 、 4 , Figure 3 for Figure 1 A partial enlarged schematic diagram of point A in the middle, Figure 4 Schematic diagram of the structure of the lower mold in the pressing jig provided for some embodiments of the present application. The lower mold 100 includes two oppositely arranged loading parts, and the loading parts include a first loading part 11 and a second loading part 12. The first loading part 11 and the second loading part 12 are respectively provided with a first receiving groove 111 and a second receiving groove 121, and the two receiving grooves are connected to each other to form a receiving part, and the substrate 31 is embedded in the receiving part. The bottoms of the first receiving groove 111 and the second receiving groove 121 (hereinafter referred to as the two receiving grooves) are relatively tilted. The bottoms of the two receiving grooves are respectively provided with a first positioning groove 112 and a second positioning groove 122 (hereinafter referred to as the two positioning grooves), and a screen is respectively embedded in the two positioning grooves, and the screen protrudes from the bottom of the groove or the surface of the screen is flush with the bottom of the groove of the groove, so that the first bonding block 311 and the second bonding block 312 are bonded to the screen in the corresponding positioning groove. The two receiving grooves are opened on the upper surfaces of the corresponding two loading parts. For example, the first receiving groove 111 is opened on the first upper surface 113 of the first loading part 11 , and the second receiving groove 121 is opened on the second upper surface 123 of the second loading part 12 .

[0057] At the same time, further combining Figure 5 , Figure 5 Schematic diagram of the structure of the upper mold in the pressing jig provided in some embodiments of the present application. The upper mold 200 includes a pressing head 21, and the pressing head 21 includes two pressing surfaces, and the two pressing surfaces are pressed on a base plate 31 embedded in the receiving portion. The two pressing surfaces include a first pressing surface 211 and a second pressing surface 212. Correspondingly, the first pressing surface 211 is pressed against the first bonding block 311 in the first receiving groove 111, and the second pressing surface 212 is pressed against the second bonding block 312 in the second receiving groove 121. The first pressing surface 211 and the second pressing surface 212 are arranged to be inclined relative to each other. Specifically, the first bonding block 311 and the second bonding block 312 form a first angle, and the angle of the first angle is α p. The inclination angles of the two pressing surfaces are consistent with the inclination angles of the bottom surfaces of the two containing grooves. That is, the two pressing surfaces are relatively inclined to form a second angle; the bottom surfaces of the two containing grooves are relatively inclined to form a second angle, and the angle of the second angle is α1. The inclination angles of the two pressing surfaces are the same as the inclination angles of the bottom surfaces of the containing grooves, and the pressing surfaces are arranged parallel to the bottom surfaces of the containing grooves, so that the substrate 31 is clamped between the pressure head 21 and the loading part. The inclination angle of the bottom surface of the positioning groove is consistent with the inclination angle of the bottom surfaces of the two containing grooves. The screen placed in the positioning groove is respectively arranged parallel to the first bonding block 311 and the second bonding block 312 to ensure the position of the first bonding block 311, the second bonding block 312 and the screen, so that the bonding accuracy of the substrate 31 and the screen is high, thereby improving the processing yield.

[0058] In the related screen bonding technology, due to the limitations of the related pressing device, the pressing device needs to press the first bonding block 311 and the first screen 32 first; after completing the first pressing, the second bonding block 312 and the second screen 33 are pressed for the second time, thereby completing the processing of the entire workpiece. However, the need for secondary pressing in the related screen bonding technology makes the process more complicated, prolongs the entire working cycle, and thus affects the processing efficiency. In this solution, the first bonding block 311 and the second bonding block 312 are simultaneously bonded to the screens in the corresponding positioning grooves to shorten the manufacturing cycle and improve work efficiency. More specifically, the angle α of the first angle p Angle α1 is equal to or approximately equal to the second included angle. The two pressing surfaces and the bottom surface of the positioning groove can also adjust the inclination angle of the first bonding block 311 and the second bonding block 312. Through pressing, the first bonding block 311 and the second bonding block 312 are deformed, so that the first bonding block 311 and the second bonding block 312 are adapted to the inclination angle of the bottom surface of the groove, thereby adapting the first bonding block 311 and the second bonding block 312 to the position of the screen to improve the bonding accuracy. The range of α1 is 10° to 170°.

[0059] Furthermore, the two loading sections are spaced apart to form a first avoidance section 13 between them. A second avoidance section 23 recessed into the pressing head 21 is provided on the pressing head 21 corresponding to the first avoidance section 13. When the pressing head 21 is pressed against the loading section, the first avoidance section 13 and the second avoidance section 23 are correspondingly assembled to form an avoidance channel.

[0060] Among them, Figure 2 As shown, combined with Figure 6 、 7 , Figure 6 This is a schematic diagram of the structure of the pressing fixture provided in some embodiments of the present application. Figure 7 for Figure 6A partial enlarged schematic diagram at point B in the figure. The substrate 31 includes a transition block 313, which extends in an arc shape. The two ends of the transition block 313 are integrally formed with the first bonding block 311 and the second bonding block 312, respectively. Specifically, the substrate 31 is bent to form a curved part. The fulcrum where the substrate 31 is bent and subjected to force is the transition block 313, and the two ends of the transition block 313 are the first bonding block 311 and the second bonding block 312. Due to the arc shape of the transition block 313, the first bonding block 311 and the second bonding block 312 are relatively tilted. The transition block 313 is accommodated in the avoidance channel.

[0061] In the actual bonding process, the angle α of the first angle p There is a deviation in size, while the angle α1 of the second angle is fixed. This makes it difficult for the first bonding block 311 and the second bonding block 312 to maintain a parallel relationship with the screen when the substrate 31 is loaded in the receiving portion, affecting the fitting accuracy of the first bonding block 311, the second bonding block 312 and the screen. To this end, the upper mold 200 needs to provide a force to deform the substrate 31 while providing adhesion between the substrate 31 and the screen, so as to adjust the inclination angle of the first bonding block 311 and the second bonding block 312. However, when the upper mold 200 presses the substrate 31, the lower mold 100 and / or the upper mold 200 preferentially fits with the transition block 313, and then under the clamping action of the pressing surface and the bottom surface of the groove, the stress is distributed on the first bonding block 311 and the second bonding block 312. Since the first bonding block 311 and the second bonding block 312 are bonded to the screen, when stress is distributed on the first bonding block 311 and the second bonding block 312, it is easy to cause the first bonding block 311 and the second bonding block 312 to deform. For example, the first bonding block 311 or the second bonding block 312 may be arched, which affects the degree of adhesion between the two bonding blocks and the screen. The arching of the two bonding blocks will lead to a reduction in the area in which the arched bonding blocks are bonded to the screen.

[0062] Among them, the angle α of the first angle p The reason for the size deviation is that the substrate 31 is prone to tolerance during the bending process. After being bent, the substrate 31 will recover to a certain extent. In existing bending processes, including hot bending, the substrate 31 is heated before being bent. However, when the substrate 31 cools, the substrate 31 will recover. Since the recovery of the substrate 31 is uncontrollable, the angle α of the first included angle of the substrate 31 will be p Size deviation.

[0063] In this solution, the transition block 313 is arranged in the avoidance channel formed by the first avoidance portion 13 and the second avoidance portion 23. The upper mold 200 is pressed on the substrate 31. The first pressing surface 211 and the second pressing surface 212 are preferentially pressed on the first bonding block 311 and the second bonding block 312, so that the stress on the substrate 31 is concentrated on the transition block 313, and the transition block 313 deforms in the avoidance channel without interfering with the upper mold 200 and the lower mold 100. At the same time, since the stress is concentrated on the transition block 313, the shapes of the two bonding blocks are maintained so that the two bonding blocks are completely bonded to the screen to improve the bonding quality. After the mold is opened, the concentrated stress at the transition block 313 is released, so that the substrate 31 returns to its original shape, so that the pressing jig is suitable for the environment where substrates 31 with different degrees of curvature are bonded to the screen.

[0064] Furthermore, inwardly recessed grooves 213 are formed on corresponding side surfaces of the ram 21, and the grooves 213 are arranged corresponding to the second escape portion 23. The provision of the grooves 213 on both sides of the ram 21 provides additional points of force on the ram 21, facilitating the gripping device's access to these points of force and enabling stable gripping of the upper die 200. Furthermore, the alignment of the grooves 213 with the second escape portion 23 facilitates the creation of a marking on the surface of the ram 21, making it easier to align the first escape portion 13 with the second escape portion 23 to form a clearance channel.

[0065] In some embodiments of the present application, the relative inclination angle of the two upper surfaces is consistent with the inclination angle of the bottoms of the two receiving grooves, forming a second angle between the first upper surface 113 and the second upper surface 123. The pressing surface is stepped, and the stepped pressing surface is pressed against the upper surface and the substrate 31 simultaneously, so that the upper mold 200 and the lower mold 100 are pressed together, and the upper mold 200 and the lower mold 100 are positioned by the pressing surface and the receiving groove to ensure the fitting accuracy of the pressing fixture.

[0066] Further, refer to Figure 8 、 9 , Figure 8 This is a schematic diagram of a portion of the structure of the lower die and workpiece of the pressing jig provided in some embodiments of the present application. Figure 9Schematic diagram of another part of the structure of the lower mold and the workpiece in the pressing jig provided in some embodiments of the present application. The upper surface includes a fitting surface and a yield surface. Specifically, the first upper surface 113 includes a first fitting surface 1131 and a first yield surface 1132, and the second upper surface 123 includes a second fitting surface 1231 and a second yield surface 1232. The second angle is formed by the first fitting surface 1131 and the second fitting surface 1231. The yield surface is deflected relative to the fitting surface, and the yield surface is deflected toward the bottom surface 17 of the lower mold 100. The first fitting surface 1131 and the second fitting surface 1231 are correspondingly fitted on the first pressing surface 211 and the second pressing surface 212, so that a gap is formed between the yield surface and the pressing surface, so that the operator or the grasping device can grasp the upper mold 200 from the gap. The angle formed by the first contact surface 1131 and the first clearance surface 1132 is α2, and the angle formed by the second contact surface 1231 and the second clearance surface 1232 is α3. For example, α2 and α3 are equal. However, it is understood that α2 and α3 can also be different. As long as the clearance surface and the pressing surface form a gap to facilitate grasping by an operator or a grasping device, it should be considered a specific embodiment of this application. The range of α2 and α3 is 5° to 85°.

[0067] On the other hand, Figure 5 As shown, the upper mold 200 further includes a carrier plate 22, the pressing head 21 is connected to the carrier plate 22, and a step portion 24 is formed at the connection between the pressing head 21 and the carrier plate 22. The step portion 24 can also facilitate an operator or a grasping device to grasp the upper mold 200 from the step portion 24.

[0068] It should be noted that, in order to facilitate gripping the upper die 200, a force-receiving portion is provided on the upper die 200. The force-receiving portion may include, but is not limited to, a notch formed between the relief surface and the pressing surface and / or a step portion 24 formed at the connection between the pressing head 21 and the carrier plate 22.

[0069] In some embodiments of the present application, Figure 4 As shown, a deep groove serving as a gripping portion is arranged around the circumference of the receiving portion, and a portion of the edge of the substrate 31 is projected into the deep groove. Specifically, the substrate 31 can cover a portion of the deep groove, allowing the gripping member to extend into the deep groove and clamp onto the edge of the substrate 31, thereby stably gripping the substrate 31.

[0070] Furthermore, the containing groove is provided on both the fitting surface and the yield surface, and the positioning groove is provided corresponding to the fitting surface, so that when the pressing surface is pressed on the fitting block, the contact area between the fitting block and the screen is large and the pressure is more uniform. Among them, the deep groove includes a first gripping portion 15 and a second gripping portion 16. The first gripping portion 15 is provided on the yield surface, while the second gripping portion 16 is provided on the fitting surface. At the same time, the number of the first gripping portion 15 and the second gripping portion 16 is at least two, and the plurality of first gripping portions 15 are arranged relative to each other. For example, the first gripping portion 15 is correspondingly provided on the first yield surface 1132 and the second yield surface 1232. The second gripping portion 16 is arranged relative to each other. The relatively provided first gripping portion 15 and the second gripping portion 16 facilitate the gripping component to clamp the substrate 31.

[0071] In some embodiments of the present application, the present application further provides an assembly device for multi-screen lamination, including the pressing jig of the above embodiment. The assembly device of this embodiment has the same beneficial effects as the pressing jig provided in the above embodiment, and will not be repeated here.

[0072] In some embodiments of the present application, Figure 3 、 4 As shown, the lower mold 100 also includes a bottom surface 17, and an air hole 14 is provided on the bottom of the positioning groove, and the air hole 14 extends to the bottom surface 17. The assembly equipment also includes an adsorption device, which is used to connect the air hole 14, and the screen is adsorbed by the adsorption device through the air hole 14 to ensure that the screen is stably fixed in the positioning groove. When the bonding block is pressed on the screen, if the inclination angle of the two bonding blocks is inconsistent with the inclination angle of the bottom surface of the positioning groove, the bonding block will first contact a part of the screen. When the pressure head 21 continues to press the substrate 31, the screen is prone to tilting due to uneven force, thereby reducing the bonding accuracy between the bonding block and the screen. On the other hand, after the bonding block and the screen are bonded, the adsorption force provided by the adsorption device can also be used to keep the substrate 31 conformed to the shape of the receiving portion to ensure the stability of the shape of the substrate 31 after deformation, so that the holding pressure is stable.

[0073] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
