Description

Technical Field

[0001] The invention relates to an automated device, in particular to a device for laminating sheets. Background Art

[0002] A conventional film sticking device is used to stick a film to a substrate, and is provided with a suction head, a fixing seat, a scraper cylinder, and a scraper. The suction head can be driven to approach and suck the film, and can move above the substrate and then release the film, so that the film falls on the substrate. Then, the scraper cylinder drives the scraper to press on the film and move back and forth, so that the film is firmly stuck on the substrate.

[0003] However, in the process of film laminating using the film laminating device, since the film is usually stacked in multiple pieces, the suction head may absorb more than one piece of the film at a time, which will cause multiple pieces of the film to be attached to the substrate, affecting the quality of the finished product and even causing rework. Summary of the invention

[0004] Therefore, an object of the present invention is to provide a sheet material feeding method which can at least overcome the disadvantages of the background technology.

[0005] Therefore, the sheet feeding method of the present invention includes: allowing a sheet of material to be picked up by a pick-and-place mechanism and brought to a measuring mechanism to measure the thickness; when the thickness of the sheet of material meets a preset range, the sheet of material is picked up by the pick-and-place unit and brought to a carrier; and when the thickness of the sheet of material does not meet the preset range, the sheet of material is picked up by the pick-and-place unit and brought to a discharge rack.

[0006] Another object of the present invention is to provide a feeding unit that can at least overcome the disadvantages of the background technology.

[0007] Therefore, the feeding unit of the present invention is provided with a first feeding mechanism, a second feeding mechanism, a first pick-up and placement mechanism, a second pick-up and placement mechanism, and a measuring mechanism. The first feeding mechanism supplies a first sheet. The second feeding mechanism supplies a second sheet. The first pick-up and placement mechanism extracts the first sheet. The second pick-up and placement mechanism extracts the second sheet. The measuring mechanism measures the thickness of the first sheet or the second sheet extracted by the first pick-up and placement mechanism or the second pick-up and placement mechanism.

[0008] Another object of the present invention is to provide a sheet laminating device that can at least overcome the shortcomings of the background technology.

[0009] The sheet material bonding device of the present invention is provided with the feeding unit, a bonding mechanism, a conveying mechanism, and a platform unit. The bonding mechanism is provided with a bonding head for bonding the first sheet material and the second sheet material. The conveying mechanism is provided with a conveying rail seat. The platform unit is driven by the conveying rail seat to pass through the first pick-and-place mechanism, the second pick-and-place mechanism, and the bonding head.

[0010] The beneficial effect of the present invention is that, through the setting of the measuring mechanism, even if multiple sheets are accidentally extracted at one time, it can be discovered by first measuring the thickness of the sheets, so as to avoid attaching multiple sheets at one time, affecting the quality of the finished product or even causing rework.

[0082] See also Figure 1 The stage unit 3 can be used to place the first sheet 91 and the second sheet 92, and is provided with two stages 31. Fig.11 , 12 Each carrier 31 is provided with a carrier seat 32 and a spacing mechanism 33. Each carrier seat 32 is provided with a table 321 on which the first sheet 91 can be placed and a plurality of heating elements 322 that can heat the table 321.

[0084] In this embodiment, the first suction hole 301 or the second suction hole 302 is a small round hole, but in other embodiments of the present invention, the first suction hole 301 or the second suction hole 302 may be a long slot hole.

[0085] See also Figure 1 The conveying mechanism 4 is extended along the second direction Y and is provided with two conveying rail seats 41 spaced apart in the first direction X. The conveying rail seats 41 can drive the carrier 31 to move respectively, and move between the first pick-and-place mechanism 13, the second pick-and-place mechanism 14, the abutting mechanism 5, and the third pick-and-place mechanism 22. In this embodiment, two carriers 31 and two conveying rail seats 41 are provided, but in other embodiments of the present invention, only one carrier 31 and only one conveying rail seat 41 may be provided respectively.

[0086] See also Figure 1 , 13 The abutting mechanism 5 is located between the second pick-and-place mechanism 14 and the third pick-and-place mechanism 22, and is provided with two abutting heads 51 and two abutting head driving members 52 installed on the second pick-and-place rail seat 141. The abutting heads 51 are located on the side of the second pick-and-place rail seat 141 opposite to the second extraction head 142, and correspond to the conveying rail seats 41 downward. Each of the abutting heads 51 is provided with a heating rod 511, and can be driven by the corresponding abutting head driving member 52 to move up and down.

[0087] The following match Figures 14 to 29 The sheet material feeding method and the sheet material bonding method of the present invention are described, wherein: Figures 14 to 17 It is about the sheet feeding method, and Figures 18 to 29 The present invention relates to a method for laminating the sheets.

[0088] First, the first pick-and-place mechanism 13 extracts the topmost first sheet 91 from the first feeding bin 111 of the first feeding mechanism 11, and moves the first sheet 91 away from the first feeding bin 111. In the process of the first pick-and-place mechanism 13 extracting the first sheet 91 and moving it away from the first feeding bin 111, the first sheet 91 passes through the first brush assembly 114. At the same time, the first pick-and-place mechanism 13 shakes the first sheet 91 up and down, so that the side edge of the first sheet 91 is brushed by the first brush assembly 114. Therefore, even if the first sheets 91 are stuck to each other and the first pick-and-place mechanism 13 extracts multiple sheets of the first sheet 91 at a time, the stuck first sheet 91 can be peeled off under the cooperation of the first brush assembly 114 and the first pick-and-place mechanism 13 shaking up and down.

[0089] After the first picking and placing mechanism 13 extracts the topmost first sheet 91 and moves it away from the first feeding mechanism 11, the first feeding lifting seat 112 of the first feeding mechanism 11 is driven upward by the first feeding lifting seat driving member 113 to push the first sheet 91 that has not been extracted upward.

[0090] See also Fig.14 The first pick-and-place mechanism 13 extracts the first sheet 91 to the upper side of the probe 152 of the measuring mechanism 15 by means of the suction nozzle 133. When the measuring mechanism 15 measures the thickness of the first sheet 91, the first sheet 91 is clamped between the reference surface S1 of the first pick-and-place mechanism 13 and the probe 152. The principle of the measuring mechanism 15 measuring the thickness is to first press the probe 152 with the platform 134 when adjusting the machine, and calculate the amplitude of the probe 152 being pressed down by the platform 134. When the first sheet 91 is clamped between the platform 134 and the probe 152, the amplitude of the probe 152 being pressed down by the first sheet 91 is calculated, thereby calculating the thickness of the first sheet 91.

[0091] See also Fig.15 When the thickness of the first sheet 91 meets a preset range, one of the carriers 31 is driven by the corresponding conveying rail seat 41 to move to the bottom of the first pick-up and placement mechanism 13. The first component 334 and the second component 335 are driven to unfold relative to each other. The first sheet 91 is extracted by the first pick-up and placement mechanism 13 and placed on the table 321 of the supporting base 32 of one of the carriers 31, and is heated by the heating element 322 to make its upper surface sticky. By means of the first suction hole 301 and a vacuum device (not shown) connected to the first suction hole 301, an adsorption force is generated to fix the first sheet 91 on the table 321. See Fig.16 , then the first extraction head 132 of the first pick-and-place mechanism 13 is driven to move upward and away from the stage unit 3. The first component 334 and the second component 335 are driven to be relatively close to each other, so that the first sheet 91 is held between the spacing component 331 and the table 321. When the thickness of the first sheet 91 does not meet the preset range, it means that another first sheet 91 may be attached below the first sheet 91. The first pick-and-place mechanism 13 will extract the first sheet 91 with inconsistent thickness to the first unloading rack 153, and then go to the first feeding mechanism 11 to re-extract another first sheet 91.

[0092] Next, the unloading rail seat 151 drives the probe 152, the first unloading rack 153, and the second unloading rack 154 to simultaneously move to the corresponding second feeding mechanism 12. The second pick-and-place mechanism 14 extracts the second sheet 92 at the top from the second feeding bin 121 of the second feeding mechanism 12, and moves the second sheet 92 away from the second feeding bin 121. In the process of the second pick-and-place mechanism 14 extracting the second sheet 92 and moving it away from the second feeding bin 121, the second sheet 92 passes through the second brush assembly 124. At the same time, the second pick-and-place mechanism 14 shakes the second sheet 92 up and down, and causes the side edge of the second sheet 92 to be brushed by the second brush assembly 124. Therefore, even if the second sheets 92 stick to each other and the second pick-and-place mechanism 14 extracts multiple pieces of the second sheets 92, the stuck second sheets 92 can be peeled off by the coordinated action of the second brush assembly 124 and the second pick-and-place mechanism 14 shaking up and down.

[0093] After the second picking and placing mechanism 14 extracts the second sheet 92 at the top and moves it away from the second feeding mechanism 12, the second feeding lifting seat 122 of the second feeding mechanism 12 is driven upward by the second feeding lifting seat driving member 123 to push the second sheet 92 that has not been extracted upward.

[0094] See also Fig.17 , the second pick-and-place mechanism 14 extracts the second sheet 92 to the upper side of the probe 152 of the measuring mechanism 15 by means of the suction cup 143. When the measuring mechanism 15 measures the thickness of the second sheet 92, the second sheet 92 is clamped between the reference surface S2 of the second pick-and-place mechanism 14 and the probe 152. The principle of the measuring mechanism 15 measuring the thickness is to first press the probe 152 with the suction cup 143 during machine adjustment, and calculate the amplitude of the probe 152 being pressed down by the suction cup 143. When the second sheet 92 is clamped between the suction cup 143 and the probe 152, the amplitude of the probe 152 being pressed down by the second sheet 92 is calculated, thereby calculating the thickness of the second sheet 92.

[0095] See also Fig.18 When the thickness of the second sheet 92 meets a preset range, the carrier 31 on which the first sheet 91 is placed is driven by the corresponding conveying rail 41 to move below the second pick-and-place mechanism 14. The second pick-and-place mechanism 14 places the second sheet 92 on the spacing member 331 and is spaced vertically apart from the first sheet 91.

[0096] Specifically, the second sheet 92 has a first sheet portion 921, a second sheet portion 922, and a third sheet portion 923 located between the first sheet portion 921 and the second sheet portion 922. The first sheet portion 921 is placed on the first component 334, the second sheet portion 922 is placed on the second component 335, and the third sheet portion 923 is suspended between the first component 334 and the second component 335, so that the second sheet 92 and the first sheet 91 are separated by a vertical distance.

[0097] See also Fig.19 After the second extraction head 142 of the second pick-and-place mechanism 14 is driven away from the carrier 31, the carrier 31 is driven by the corresponding conveying rail seat 41 to move to the lower side of the abutting mechanism 5. Fig. 20 , 21 The abutting head 51 is driven to move downward, and exerts a force on the third sheet portion 923 of the second sheet material 92 to abut against the first sheet material 91, and the third sheet portion 923 of the second sheet material 92 can be heated by the heating element 322. Fig. 22 After the third sheet 923 is attached to the upper surface of the first sheet 91, the carrier 31 is driven by the corresponding conveying rail seat 41 to move relative to the abutting head 51 in a direction opposite to the second direction Y. At this time, the abutting head 51 is displaced relative to the second sheet 92 between the first component 334 and the second component 335, and pushes the first sheet 921 to adhere to the upper surface of the first sheet 91 in a rolling manner, and the first sheet 921 of the second sheet 92 can be heated by the heating element 322.

[0098] See also Fig.23 , the first component 334 is pushed away from the table 321 by the abutment head 51. Fig.24 , the carrier 31 is driven by the corresponding conveying rail seat 41 to move along the second direction Y. At this time, the abutting head 51 pushes the second sheet 922 to adhere to the upper surface of the first sheet 91 in a rolling manner, and the second sheet 922 of the second sheet 92 can be heated by the heating element 322. Fig.25 , the second component 335 is pushed away from the table 321 by the abutting head 51. At this stage, the first sheet 91 and the second sheet 92 are affixed to each other to form the composite 93.

[0099] See also Fig.26 , the contact head 51 is driven to move upward, and the carrier 31 is driven by the corresponding conveying rail seat 41 to move toward the third pick-and-place mechanism 22. Fig. 27, the third extraction head 222 of the third pick-and-place mechanism 22 is driven to move toward the carrier 31 and move downward to abut against the composition 93. At this time, the vacuum device (not shown) connected to the first suction hole 301 is closed, the adsorption force between the table 321 and the composition 93 disappears, and the suction cup 223 of the third extraction head 222 of the third pick-and-place mechanism 22 extracts the composition 93 instead.

[0100] See also Fig.28 The third pick-and-place mechanism 22 takes the composition 93 and moves it upward to the receiving mechanism 21. Fig.29 The composition 93 is picked up by the third pick-and-place mechanism 22 and placed in the receiving bin 211 of the receiving mechanism 21, and the composition 93 is located on the receiving bottom plate 218. The pressing plate 214 is driven into the receiving bin 211 and pressed downward against the composition 93, so that the composition 93 is clamped between the pressing plate 214 and the receiving bottom plate 218 of the receiving lifting seat 212, so as to flatten the composition 93 and prevent the composition 93 from warping.

[0101] In summary, the sheet feeding method, sheet bonding equipment and feeding unit of the present invention, through the setting of the measuring mechanism 15, even if multiple sheets 9 are accidentally extracted at one time, it can be discovered by first measuring the thickness of the sheet 9, so as to avoid attaching multiple sheets 9 at one time, affecting the quality of the finished product or even causing rework, so the purpose of the present invention can be achieved.

[0102] However, the above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and the patent specification of the present invention are still within the scope of the present invention.
