Description

Technical Field

[0001] The present invention relates to the field of curved screen processing, and in particular to an energy-saving laminating device for curved screen processing. Background Art

[0002] During the production process of curved monitors, a protective film needs to be applied manually on the screen. However, since a protective film of the same size as the screen is easily skewed and cannot fully cover the screen, a screen film is applied by applying a film that is larger than the screen and then cutting off the excess part to complete the application of the monitor screen. This greatly reduces the efficiency of manual application of the monitor screen film.

[0003] Moreover, since dust is easily absorbed on the protective film and the screen during application, bubbles are easily generated during application of the protective film, which requires manual work to tear off the applied protective film and re-apply the film, greatly reducing the efficiency of the application.

DETAILED DESCRIPTION

[0028] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," "downwardly," and the like are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0029] Example 1

[0030] An energy-saving curved screen processing bonding device, such as Figure 1-4 As shown, it includes a workbench 1, a first push rod 2, a first fixed plate 3, an extrusion plate 4 and a power assembly; the workbench 1 is connected to the power assembly, which is connected to four rectangularly distributed first push rods 2, and the power assembly is used to drive the first push rods 2 to move left or right; the telescopic ends of all the first push rods 2 are fixedly connected to a first fixed plate 3; the first fixed plate 3 on the left is fixedly connected to the extrusion plate 4;

[0031] It also includes an air suction plate 5, a raw material winding roller 6, a first motor 7, a waste winding roller 8, a second motor 9 and a cutting assembly; all the first push rods 2 on the right are fixedly connected to the air suction plate 5, and the air suction plate 5 is externally connected to an air pump, and the protective film is adhered to the screen through the air suction plate 5; the right part of the workbench 1 is rotatably connected to the raw material winding roller 6; the right part of the workbench 1 is fixedly connected to the first motor 7, and the output shaft of the first motor 7 is fixedly connected to the raw material winding roller 6; the left part of the workbench 1 is rotatably connected to the waste winding roller 8; the left part of the workbench 1 is bolted to the second motor 9, and the output shaft of the second motor 9 is fixedly connected to the waste winding roller 8; the workbench 1 is connected to a cutting assembly, which is used to cut off the film that is not adhered to the display screen.

[0032] The power assembly includes a first slide rail 101 and a first slider 102; two first slide rails 101 distributed front and back are fixedly connected to the upper part of the workbench 1; all the first slide rails 101 are slidably connected to two first sliders 102; all the first sliders 102 are fixedly connected to the adjacent first push rods 2.

[0033] The working steps of the above embodiment are as follows: first, manually place the curved display on the workbench 1, then manually stick the beginning end of the protective film rolled on the raw material winding roller 6 to the waste material winding roller 8 after passing through the top of the suction plate 5 and the bottom of the extrusion plate 4, then push the first fixed plate 3 downward by the first push rod 2 on the left, so that the first fixed plate 3 drives the extrusion plate 4 to move downward, and when the extrusion plate 4 contacts the display screen, it stops moving downward, and then drives the extrusion plate 4 to move to the right by the first slider 102. Since the screen of the display is a curved surface, when the extrusion plate 4 moves to the right, the first push rod 2 pushes the extrusion plate 4 downward, so that the extrusion plate 4 can always stick the protective film to the display screen. After the protective film is applied three to five centimeters from the left end of the display screen, the first slider 102 on the right drives the suction plate 5 to move to the left. When the suction plate 5 contacts the position where the pressing plate 4 has applied the protective film, the air pump connected to the suction plate 5 is activated, thereby sucking air through the suction port 5a of the suction plate 5, sucking away dust on the protective film and the screen, and sticking the protective film to the screen. Then, the first slider 102 on the left and the first push rod 2 continue to drive the pressing plate 4 to move rightward and downward, thereby further fixing the protective film stuck to the screen by the suction plate 5. When both the suction plate 5 and the pressing plate 4 move to the right of the screen, the pressing plate 4 is reset by the first slider 102, completing the film application on the display.

[0034] Then the cutting assembly is used to cut off the part of the protective film that is not attached to the screen, thereby completing the cutting of the protective film. The cut display screen is then manually removed, and a new display screen that has not been laminated is then manually placed on the workbench 1. The first motor 7 and the second motor 9 drive the waste winding roller 8 and the raw material winding roller 6 to rotate respectively, so that the new uncut protective film is unfolded, and the next film lamination is carried out.

[0035] Example 2

[0036] On the basis of Example 1, Figure 5-8As shown, the cutting assembly includes a second slide rail 201, a second slider 202, a second push rod 203, a second fixed plate 204, a first cutter 205, a first spring telescopic rod 206, a third fixed plate 207 and a first roller 208; the front and rear parts of the workbench 1 are fixedly connected to a second slide rail 201; all the second slide rails 201 are slidably connected to two second sliders 202; all the second sliders 202 are fixedly connected to a second push rod 203; the telescopic ends of all the second push rods 203 are fixedly connected to a second fixed plate 204; all the second fixed plates 204 are fixedly connected to a first cutter 205, and the front and rear sides of the part of the protective film that is not attached to the screen are cut by the first cutter 205; all the second fixed plates 204 are fixedly connected to a first spring telescopic rod 206; the telescopic ends of all the first spring telescopic rods 206 are fixedly connected to a third fixed plate 207; all the third fixed plates 207 are rotatably connected to a first roller 208.

[0037] The cutting assembly also includes a third slide rail 2010, a third slider 2011, a third push rod 2012, a fourth fixed plate 2013, a third spring telescopic rod 2014, a sixth fixed plate 2015, a third roller 2016 and a second cutter 2017; the left and right parts of the workbench 1 are bolted to a third slide rail 2010; all third slide rails 2010 are slidably connected to a third slider 2011; all third sliders 2011 are fixedly connected to a third push rod 2012; all telescopic ends of the third push rods 2012 are fixedly connected to a third Four fixed plates 2013; all fourth fixed plates 2013 are fixedly connected to a third spring telescopic rod 2014; the telescopic ends of all third spring telescopic rods 2014 are fixedly connected to a sixth fixed plate 2015; all sixth fixed plates 2015 are rotatably connected to a third roller 2016; all fourth fixed plates 2013 are fixedly connected to a second cutter 2017, and the second cutter 2017 is slidably connected to the sixth fixed plate 2015, and the second cutter 2017 is used to cut the left and right sides of the part of the protective film that is not attached to the screen.

[0038] It also includes four cutting corner units and a fixing bar 216; the workbench 1 is fixedly connected to two fixing bars 216; the cutting corner unit includes a fourth push rod 211, a fifth fixing plate 212, a second spring telescopic rod 213, a third cutter 214 and a fixing bar 216; the workbench 1 is fixedly connected to the fourth push rod 211; the telescopic end of the fourth push rod 211 is fixedly connected to the fifth fixing plate 212; the fifth fixing plate 212 is fixedly connected to the second spring telescopic rod 213; the second spring telescopic rod 213 is fixedly connected to the third cutter 214, and the third cutter 214 is L-shaped. The four corners of the protective film that are not attached to the screen are cut by the third cutter 214, thereby preventing the second cutter 2017 and the first cutter 205 from easily cutting the part outside the right-angled edge when cutting to the right-angled edge, which makes it easy to break the protective film when pulling it.

[0039] It also includes a second roller 2018; all first fixed plates 3 are rotatably connected to two second rollers 2018, and the unbonded portion of the protective film is fixed by the cooperation of the second roller 2018 and the first roller 208, so that cutting can be performed better.

[0040] The cutting corner unit also includes an extrusion block 215; the fifth fixed plate 212 is fixedly connected to the extrusion block 215, and the extrusion block 215 is slidably connected to the third cutter 214. The extrusion block 215 is used to re-tighten the cut part of the protective film, thereby preventing the first roller 208 and the second roller 2018 from driving the cut part of the protective film to move, causing the uncut part of the protective film to warp up.

[0041] It also includes an airbag 2019; all fixing strips 216 are fixedly connected to an airbag 2019, and the airbag 2019 is externally connected to an air pump, and the airbag 2019 is long and narrow, and the front and rear sides of the front and rear airbags 2019 are aligned with the front and rear sides of the screen respectively. The airbag 2019 is used to press down the parts around the cutting position that are in contact with the screen, thereby preventing the protective film of the contact part from being affected during cutting.

[0042] The working steps of the above embodiment are as follows: when the protective film is applied, the left and right airbags 2019 are driven by the first slider 102 to move in opposite directions. When the left side of the airbag 2019 is aligned with the left side of the display screen or the right side of the airbag 2019 is aligned with the right side of the display screen, the airbag 2019 stops moving. Then, an air pump connected to the airbag 2019 is started to input air into the airbag 2019, causing the airbag 2019 to swell. The four corners of the portion where the protective film and the screen are attached are pressed by the airbag 2019, so that the protective film at the corners will not be warped when the corners are subsequently cut.

[0043] Then, the fourth push rod 211 pushes the fifth fixing plate 212 upward, thereby the fifth fixing plate 212 drives the second spring telescopic rod 213, the third cutter 214, and the extrusion block 215 to move upward. Since the third cutter 214 is set in an L shape, the third cutter 214 can cut the four corners of the part where the protective film and the screen are attached;

[0044] Then the second slider 202 drives the left and right second push rods 203 to move in opposite directions, and then the second push rods 203 drive the second fixing plate 204, the first cutter 205, the first spring telescopic rod 206 and all the parts connected thereto to move in opposite directions. When the first cutter 205 contacts the third cutter 214, the movement is stopped. Then the first slider 102 drives the second rollers 2018 to move above the adjacent first rollers 208 respectively, and then the second push rods 203 push the first rollers 208 to move upward, so that the front and rear parts of the protective film that are not in contact with the screen are fixed by the second rollers 2018 and the first rollers 208, and the airbag 20 19 fixes the protective film and the screen bonding part, thereby facilitating the subsequent cutting of the front and rear parts of the protective film that are not bonded to the screen. After continuing to move upward, the first roller 208 is squeezed by the second roller 2018, so that the first roller 208 cannot continue to move upward, so that after continuing to move upward, the first cutter 205 moves to the top of the first roller 208, and then the protective film is pierced by the first cutter 205. At this time, the first spring telescopic rod 206 is in a compressed state, and then the front and rear first cutters 205 are driven to move toward each other by the second slider 202, thereby cutting the front and rear parts of the protective film and the screen bonding part, and in the process of moving In the process, the first push rod 202 and the second push rod 203 enable the first cutter 205 to move along the curved edge of the screen, and because the screen is curved, the cut portion of the protective film is in a loose state, resulting in the second roller 2018 and the first roller 208 moving to pull the cut portion of the protective film to move, so that the uncut protective film is squeezed by the cut portion of the protective film, causing the uncut protective film to warp. Therefore, during the movement, the fourth push rod 211 continues to push the fifth fixing plate 212 upward, thereby driving the squeezing block 215 to move upward. Since the third cutter 214 contacts the fixing bar 216, the third The cutter 214 cannot move upward any further. At this time, the second spring telescopic rod 213 is in a compressed state, so that the squeeze block 215 moves upward to re-tighten the loosened cut portion of the protective film, so that the movement of the second roller 2018 and the first roller 208 cannot drive the cut portion of the protective film to move. When the front first cutter 205 and the rear first cutter 205 come into contact, the second push rod 203 pushes all the first cutters 205 upward again, thereby cutting the protective film between the front first cutter 205 and the rear first cutter 205, thereby completing the cutting of the front and rear portions of the protective film that are not in contact with the screen.

[0045] Then, the third push rod 2012 is driven forward by the third slider 2011, thereby the third push rod 2012 drives the fourth fixing plate 2013, the third spring telescopic rod 2014, the sixth fixing plate 2015 and all the parts connected thereto to move forward. When the second cutter 217 contacts the third cutter 214 in front, it stops moving. Then, the third push rod 2012 pushes the third roller 2016 to move upward. When the third roller 2016 contacts the fixing bar 216, the third roller 2016 is rotated. 2016 and the fixing bar 216 fix the left and right parts of the protective film and the screen, and then the third push rod 2012 continues to push, so that the second cutter 2017 continues to move upward to pierce the protective film, and then the second cutter 2017 is driven to move backward by the third slider 2011. When the second cutter 2017 contacts the third cutter 214 at the rear, it stops moving backward, thereby completing the cutting of the left and right parts of the part of the protective film that is not in contact with the screen, and then completing the cutting of the protective film.

[0046] Example 3

[0047] On the basis of Example 2, Figure 2-3 and Figure 4-6 As shown, it also includes a first motor 303 and a second motor 304; all third fixed plates 207 are bolted to a first motor 303, and the output shaft of the first motor 303 is fixedly connected to the first roller 208; all first fixed plates 3 are fixedly connected to a second motor 304, and the output shaft of the second motor 304 is fixedly connected to the adjacent second roller 2018, and the position where the protective film is broken is first fixed by the first roller 208 and the second roller 2018, and the first motor 303 and the second motor 304 drive the first roller 208 and the second roller 2018 to rotate to pull the protective film to move to the waste winding roller 8 for winding.

[0048] It also includes a first fixing cloth 209 and a second fixing cloth 2020; the first fixing cloth 209 is wound around the first roller 208, and the first fixing cloth 209 is provided with a magnetic metal sheet; the second fixing cloth 2020 is wound around the second roller 2018, and the second fixing cloth 2020 is provided with a magnet sheet, and the first fixing cloth 209 and the second fixing cloth 2020 cooperate with each other, and the protective films of the first roller 208 and the second roller 2018 that have passed the position are fixed by the first fixing cloth 209 and the second fixing cloth 2020, thereby preventing the first roller 208 and the second roller 2018 from moving and pulling the protective film off again; an electromagnet part 216a is provided under the fixing bar 216, and the beginning end of the first fixing cloth 209 is fixed by the electromagnet part 216a.

[0049] It also includes a fifth push rod 301, a pushing plate 305 and a winding plate 302; the workbench 1 is fixedly connected to two fifth push rods 301 distributed front and back; the telescopic ends of all the fifth push rods 301 are fixedly connected to the pushing plate 305; the workbench 1 is rotatably connected to the winding plate 302, and the winding plate 302 is located above the pushing plate 305, and the broken part of the protective film is attached to the waste winding roller 8 through the winding plate 302, so that the broken part of the protective film is rolled up.

[0050] The working steps of the above embodiment are as follows: after cutting, the cut protective film needs to be rolled up by rotating the waste winding roller 8 and the raw material winding roller 6, and some parts of the protective film will be thinner after cutting, which makes it easy to break the protective film after pulling, making it impossible for the present invention to operate continuously. Therefore, after the cutting of the protective film is completed, the front and rear second rollers 2018 are driven to move in opposite directions by the first slider 102, and the second rollers 2018 are driven to rotate by the second motor 304 during the movement, thereby rolling up the unfolded second fixed cloth 2020, and when the second roller 2018 contacts the fixed bar 216, it stops moving, thereby completing the reset. , then the second slider 202 drives the front and rear first rollers 208 to move in opposite directions respectively. When the first roller 208 moves to the bottom of the adjacent fixing bar 216, it stops moving. Then the second push rod 203 pushes the first roller 208 to move upward. When the first roller 208 contacts the fixing bar 216, it stops moving. At this time, the magnetic metal sheet on the first fixing cloth 209 will be attracted by the electromagnet part 216a. Then, the first motor 303 drives the first roller 208 to rotate, thereby fixing the beginning end of the first fixing cloth 209 on the electromagnet part 216a. Since the protective film is located between the first roller 208 and the fixing bar 216 at this time, This can clamp the protective film between the first roller 208 and the fixing strip 216, and the fixing strip 216 is located at the left and right ends of the cut portion, so that the broken portion of the protective film can be fixed later by the first roller 208 and the second roller 2018 moving toward each other, and then the front and rear first rollers 208 are driven to move toward each other by the second slider 202. Since the leading end of the first fixing cloth 209 is fixed to the electromagnet part 216a, the first fixing cloth 209 can be unfolded. When the first roller 208 moves below the second roller 2018, the second roller 2018 is driven by the second slider 202 to move synchronously with the first roller 208. One end of the leading end of the second fixing cloth 2020 is fixedly connected to the fixing strip 216, so that the second roller 2018 can move toward each other to unfold the second fixing cloth 2020, and then the magnet sheet on the second fixing cloth 2020 can attract the magnetic metal sheet on the first fixing cloth 209, thereby fixing the protective film at the position where the second roller 2018 and the first roller 208 pass, thereby preventing the protective film from being broken again due to the movement of the second roller 2018 and the first roller 208. When the front and rear first rollers 208 contact each other, the broken part of the protective film is fixed between the second fixing cloth 2020 and the first fixing cloth 209.

[0051] Then, the first slider 102 and the second slider 202 drive all the second rollers 2018 and the first roller 208 to move to the left respectively, and in the process of moving, the left first motor 303 and the second motor 304 drive the left second roller 2018 and the first roller 208 to rotate, so that the left second fixed cloth 2020 and the first fixed cloth 209 are rolled up, and the first motor 7 and the second motor 9 drive the raw material winding roller 6 and the waste winding roller 8 to rotate, so that the cut protective film is rolled up, and when the left second roller 2018 contacts the left fixed bar 216, the second roller 2018 and the first roller 208 stop moving to the left, and then the electromagnet part 216a is closed, so that the electromagnet part 216a no longer sucks the beginning end of the first fixed cloth 209, and then drives the first roller 208 to rotate through the first motor 303, thereby pulling the protective film to move to the left, and cooperates with the rotation of the raw material winding roller 6 and the waste winding roller 8 to wind up the protective film moving to the left. When the broken part of the protective film is located on the winding plate 302, the fifth push rod 301 pushes the pushing plate 305 to move upward, thereby pushing the winding plate 302 to rotate in the direction close to the waste winding roller 8, thereby making the broken part of the protective film fit on the waste winding roller 8, and then the broken part of the protective film is wound in by the rotation of the waste winding roller 8, thereby completing the winding up of the protective film when the protective film is broken, thereby maintaining the continuous operation of the present invention.

[0052] While the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised without departing from the scope of the invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
