Description

Adsorption device, bonding fixture and bonding method

The present invention relates to an adsorption device, a bonding fixture, and a bonding method.

Currently, in the manufacture or assembly of electronic products such as liquid crystal displays or touch panels, it is often necessary to bond the two substrates together. For example, the structure of a liquid crystal display generally comprises two glass substrates, a sealant coated between the two glass substrates, and a liquid crystal filled in a space formed by the sealant and the two glass substrates. A method of injecting a liquid crystal into a space formed by a sealant and two glass substrates is currently the most commonly used one drop filling (ODF). The method comprises the steps of: coating the sealant on a horizontally placed glass substrate, uniformly distributing the liquid crystal in a space formed by the sealant and the glass substrate by using a liquid crystal dispenser, and then placing another glass in a vacuum environment. The substrate is bonded thereto, and the sealant is cured to firmly bond the two glass substrates. In the conventional substrate bonding apparatus, under the vacuum condition, the first substrate to be bonded is adsorbed by the electrostatic chuck, and then moved toward the second substrate placed on the table, and the first substrate and the second substrate are bonded.

In addition, during the assembly process of the liquid crystal display, the flexible printed circuit (FPC) of the display panel module is usually bent to fit to the back of the display panel module, thereby being used with other modules in the liquid crystal display.

That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic representation.

Please refer to FIG. 1A, FIG. 1B, and FIG. 1C. 1A is a cross-sectional view showing the adsorption device 1 in which the adsorption plate 10 has not been pressed against the plane P, in accordance with an embodiment of the present invention. FIG. 1B is another cross-sectional view showing the adsorption device 1 in FIG. 1A in which the adsorption plate 10 is pressed against the plane P. 1C is a cross-sectional view showing the adsorption device 1 of FIG. 1A in which the adsorption plate 10 releases the object 2 on the plane P and leaves the plane P.

As shown in FIG. 1A, FIG. 1B and FIG. 1C, the adsorption device 1 of the present invention can be applied to adsorb the object 2, and simultaneously release the state of the adsorbed object 2 when abutting against the plane P, thereby releasing the object 2 to On the plane P. In other words, as long as there is a need to fit the two substrates together in any product. In this case, the adsorption device 1 of the present invention can be applied to perform the functions of adsorption, pressure, and simultaneous release of the substrate. The details of the various embodiments of the invention are set forth below.

As shown in FIG. 1A, in the present embodiment, the adsorption device 1 includes an adsorption plate 10, a lifting block 12, an air extraction module 14, and a reset module 16. The adsorption plate 10 of the adsorption device 1 includes a plurality of adsorption holes 100, a gas release hole 102, and a through hole 104 penetrating the adsorption plate 10. The adsorption hole 100 of the adsorption plate 10 is located on the first side 10a of the adsorption plate 10 (that is, the lower side of the adsorption plate 10). The vent hole 102 of the adsorption plate 10 is located on the second side 10b of the adsorption plate 10 with respect to the first side 10a (that is, the upper side of the adsorption plate 10). The adsorption hole 100 of the adsorption plate 10 is in communication with the bleed hole 102. The lifting block 12 of the adsorption device 1 includes a cover portion 120 and a sliding portion 122. The cover portion 120 of the floating block 12 is located on the second side 10b of the adsorption plate 10 and can be used to cover the air vent 102. The sliding portion 122 of the floating block 12 is slidably disposed in the through hole 104 of the adsorption plate 10. The length of the sliding portion 122 of the floating block 12 is greater than the thickness of the suction plate 10. The sliding portion 122 of the floating block 12 is connected to the cover portion 120 near one end of the second side 10b. The cover portion 120 of the floating block 12 can cover or leave the vent hole 102 as the sliding portion 122 slides relative to the through hole 104. When the cover portion 120 of the floating block 12 covers the vent hole 102, the sliding portion 122 of the floating block 12 near the other end of the first side 10a of the suction plate 10 may protrude from the first side 10a.

The air suction module 14 of the adsorption device 1 communicates with the adsorption hole 100 of the adsorption plate 10 and the air release hole 102, and can generate a negative pressure. Thereby, the negative pressure generated by the air suction module 14 can adsorb the object 2 to the first side 10a via the adsorption hole 100 of the adsorption plate 10, and simultaneously cover the floating block 12 via the air leakage hole 102 of the adsorption plate 10. The joint 120 is attracted to the second side 10b. In the present embodiment, the air suction module 14 of the adsorption device 1 is disposed on the second side 10b of the adsorption plate 10, but Not limited to this. In another embodiment, the suction module 14 of the adsorption device 1 can also be of a separate design from the adsorption plate 10.

In addition, the reset module 16 of the adsorption device 1 includes an abutting member and an elastic member 162. In this embodiment, the abutting member of the resetting module 16 is a cover body 160 and is disposed on the second side 10b of the adsorption plate 10, and can be used for accommodating the cover portion 120 and the elastic member 162 of the lifting block 12 and covering Above the vent hole 102 of the adsorption plate 10. The elastic member 162 of the reset module 16 is compressed between the cover 160 and the cover portion 120 of the lifting block 12. In addition, the cover 160 of the reset module 16 has a through hole 160a. The through hole 160a of the cover body 160 can communicate with the vent hole 102 when the cover portion 120 of the lifting block 12 leaves the vent hole 102 of the adsorption plate 10 (that is, the outside air can enter the cover body 160 by the through hole 160a of the cover body 160, And entering the adsorption plate 10 by the vent hole 102 of the adsorption plate 10. Thereby, the elastic member 162 of the reset module 16 can press the cover portion 120 of the lifting block 12 toward the second side 10b of the adsorption plate 10 and reliably cover the air vent 102, thereby avoiding the suction module 14 The resulting negative pressure is destroyed. In this embodiment, the elastic member 162 of the reset module 16 may be a compression spring, but is not limited thereto.

As shown in FIG. 1B, in the present embodiment, when the suction plate 10 of the adsorption device 1 abuts against the plane P with its first side 10a, the sliding portion 122 of the lifting block 12 is subjected to the reaction force of the plane P. It is pushed into the through hole 104 of the suction plate 10, and at the same time, the cover portion 120 of the floating block 12 is moved away from the vent hole 102 on the second side 10b of the adsorption plate 10 and the elastic member 162 is compressed. At this time, since the cover portion 120 of the floating block 12 is separated from the air vent 102, the negative pressure generated by the air suction module 14 is broken, and the object 2 cannot be adsorbed through the adsorption hole 100. Therefore, the object 2 is released from the adsorption hole 100 and released to the flat. Face P.

It should be noted that, in the present embodiment, when the cover portion 120 of the floating block 12 abuts against the second side 10b of the adsorption plate 10 and covers the air vent 102, the sliding portion 122 of the floating block 12 is protruded and adsorbed. The length of the first side 10a of the plate 10 is 2 mm, but is not limited thereto. The length of the sliding portion 122 of the lifting block 12 protruding from the first side 10a of the suction plate 10 can be elastically adjusted in accordance with the thickness of the article 2, provided that it is greater than the thickness of the article 2. If the sliding portion 122 of the lifting block 12 protrudes from the first side 10a of the suction plate 10 by a length smaller than the thickness of the object 2, when the suction plate 10 of the adsorption device 1 abuts against the plane P with its first side 10a, the thickness is higher. The large object 2 will first abut against the plane P and cause the sliding portion 122 of the floating block 12 to be in contact with the plane P. Therefore, the cover portion 120 of the floating block 12 does not leave the air vent 102 located on the second side 10b of the adsorption plate 10, and cannot damage the negative pressure generated by the air suction module, thereby causing the object 2 adsorbed by the adsorption hole 100 to be adsorbed. Unable to get released.

As shown in FIG. 1C, in the present embodiment, during the process in which the adsorption plate 10 of the adsorption device 1 gradually leaves the plane P, the reset module 16 is compressed between the cover portion 120 of the floating block 12 and the cover 160. The elastic member 162 is elastically restored, and the cover portion 120 of the lifting block 12 is pressed against the second side 10b of the suction plate 10. After the adsorption plate 10 of the adsorption device 1 completely leaves the plane P, the elastic member 162 of the reset module 16 presses the cover portion 120 of the floating block 12 against the second side 10b of the adsorption plate 10 to cover the air leakage hole 102. At the same time, the sliding portion 122 of the floating block 12 slides relative to the through hole 104 of the suction plate 10 as the cover portion 120 moves, and re-projects to the original position on the first side 10a of the suction plate 10.

Thereby, the operator can repeatedly cover another object 2 on the adsorption plate. The adsorption hole 100 of 10 recovers the negative pressure generated by the suction module 14 and adsorbs the other object 2 to the first side 10a of the adsorption plate 10. The adsorption device 1 of the present invention can repeat the above actions to achieve the function of adsorbing the article 2, the embossing member 2 to the plane P, and releasing the object 2 on the plane P.

In the present embodiment, the adsorption plate 10 of the adsorption device 1 is only used to adsorb an object 2, but the invention is not limited thereto. In another embodiment, the purpose of simultaneously adsorbing a plurality of objects 2 can be achieved by increasing the length of the adsorption plate 10 of the adsorption device 1 and the number of adsorption holes 100 on the first side 10a of the adsorption plate 10.

It should be noted that, if the adsorption device 1 of the present invention is horizontal or vertical movement without reverse action during the operation, after the adsorption plate 10 leaves the plane P, the floating block 12 of the adsorption device 1 can be The deflation hole 102 is reset and covered by the sliding of the through hole 104 of the suction plate 10 by its own gravity, so that the above-described reset module 16 can be omitted.

Please refer to Figure 2. Fig. 2 is a cross-sectional view showing an adsorption device 1 according to another embodiment of the present invention.

As shown in Fig. 2, in the present embodiment, the adsorption device 1 also includes the adsorption plate 10, the lifting block 12, and the suction module 14, and therefore will not be described again.

The elastic piece 36 of the adsorption device 1 has a fixed end 360 and an abutting end 362. The fixed end 360 of the elastic piece 36 is fixed to the second side 10b of the suction plate 10. The abutting end 362 of the elastic piece 36 is used to press the cover portion 120 of the floating block 12 toward the second side 10b. Thereby, the elastic piece 36 can press the cover portion 120 of the floating block 12 toward the second side 10b of the adsorption plate 10 by the abutting end 362 and reliably cover the leakage. The air hole 102 is used to prevent the negative pressure generated by the air suction module 14 from being destroyed. Moreover, when the adsorption plate 10 of the adsorption device 1 is pressed against the plane P and gradually leaves the plane P, the elastic piece 36 for pressing against the cover portion 120 of the floating block 12 elastically recovers, thereby abutting the end. 362 presses the cover portion 120 of the floating block 12 toward the second side 10b of the suction plate 10. After the suction plate 10 of the adsorption device 1 completely leaves the plane P, the abutting end 362 of the elastic piece 36 causes the cover portion 120 of the floating block 12 to press against the second side 10b of the adsorption plate 10 to cover the air leakage hole 102. At the same time, the sliding portion 122 of the floating block 12 slides relative to the through hole 104 of the suction plate 10 as the cover portion 120 moves, and the first side 10a of the re-adsorption plate 10 protrudes to the original position.

The elastic member 562 of the reset module 56 is compressed between the cantilever 560b and the cover portion 120 of the lifting block 12. Thereby, the elastic member 562 of the reset module 56 can press the cover portion 120 of the lifting block 12 toward the second side 10b of the adsorption plate 10 and reliably cover the vent hole 102, thereby avoiding the suction module 14 The resulting negative pressure is destroyed. And, when the suction plate 10 of the adsorption device 1 is pressed against the plane P and gradually leaves the plane P, the elastic member 562 for pressing against the cover portion 120 of the floating block 12 The elastic recovery is performed, and the cover portion 120 of the floating block 12 is pressed against the second side 10b of the suction plate 10.

The adsorption hole of the adsorption plate is located on the first side of the adsorption plate. The bleed hole of the absorbing plate is located on the second side of the absorbing plate relative to the first side. The adsorption hole of the adsorption plate is in communication with the gas release hole. The air suction module connects the adsorption hole and the air release hole to generate a negative pressure. The lifting block of the fitting jig includes a cover portion and a sliding portion. The cover portion of the lifting block is located on the second side for covering the air venting hole on the second side of the adsorption plate. The sliding portion of the floating block is slidably disposed in the through hole of the adsorption plate.
