Description

Technical Field

[0001] The invention relates to the technical field of auxiliary material pasting machines, and in particular to a VC metal sheet pasting machine. Background Art

[0002] VC metal sheet, also known as VC heat spreader, is a metal sheet used for heat dissipation, usually in a regular geometric shape, such as a rectangular metal sheet. VC metal sheet is used as an auxiliary material in the production process of products such as mobile phones or tablets and is attached to the product in locations including but not limited to the middle frame, front, back, and interior. Currently, the industry generally uses manual pasting of VC metal sheets, which has lower stability and efficiency than mechanical equipment.

[0003] Moreover, VC metal sheets are usually fed by placing them in a tray. When multiple trays are stacked, the feeding efficiency is challenged, which limits the production efficiency of VC metal sheets. The feeding device of the existing mechanical equipment is only suitable for incoming materials in the form of coils, not in the form of trays.

[0004] In the above situation, there is an urgent need for a VC metal sheet laminating machine that can achieve efficient feeding effect, high degree of automation, high production efficiency, strong versatility, and is suitable for situations where the incoming material is a tray. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a VC metal sheet bonding machine, which can stack multiple trays through a first supporting mechanism and a first lifting mechanism, and then provide the VC metal sheets on the trays to the bonding device through a conveying mechanism, and finally attach the VC metal sheets to the product through the bonding device. It can achieve efficient feeding effect, high degree of automation, high production efficiency and strong versatility.

[0006] The present invention provides a VC metal sheet bonding machine, comprising a frame and a feeding device and a bonding device arranged on the frame;

[0007] The feeding device includes a conveying mechanism, a first lifting mechanism and a first supporting mechanism. A plurality of trays are stacked on the first lifting mechanism. After the first supporting mechanism is inserted into the gap between the trays and supports some of the trays, the first lifting mechanism moves the remaining trays to the conveying mechanism. The conveying mechanism is used to provide the VC metal sheets in the remaining trays to the material attaching device.

[0008] The material attaching device is used to attach the VC metal sheet provided by the material feeding device to the product.

[0009] Furthermore, the first lifting mechanism includes a lifting tray, and the maximum rising height of the lifting tray is greater than the height of the first supporting mechanism.

[0010] Furthermore, the first supporting mechanism includes an insert and a first driving mechanism, the first driving mechanism is used to drive the insert to extend or retract; the first supporting mechanism is arranged next to the first lifting mechanism, when the insert is extended to the bottom of the tray, the first lifting mechanism moves away from the tray so that the insert lifts the tray; when the first lifting mechanism moves to lift the tray again so that the tray is separated from the insert, the insert retracts to move away from the tray.

[0011] Furthermore, the feeding device also includes a limit member, which is fixedly arranged next to the first supporting mechanism, and the limit member is abutted against the side of the material tray on the first supporting mechanism to limit the displacement of the material tray; there is a gap between the limit member and the conveying mechanism, and the gap is greater than or equal to the height of the material tray, so as to allow the material tray on the conveying mechanism to pass through the limit member.

[0012] Furthermore, the positional relationship between the material tray and the first lifting mechanism is arranged so that a part of the material tray is placed on and lifted by the first lifting mechanism, and another part of the material tray is suspended in the air; when the first lifting mechanism moves, another part of the material tray is placed on and lifted by the conveying mechanism, at which time the material tray is separated from the first lifting mechanism.

[0013] Furthermore, the transport mechanism includes a first conveyor belt and a transport suction head; the first conveyor belt is arranged next to the first lifting mechanism, and the first lifting mechanism moves the remaining part of the material tray to the first conveyor belt; the transport suction head is used to suck the VC metal sheet in the material tray on the first conveyor belt and move it to the material pasting device.

[0014] Furthermore, the transport mechanism also includes a second lifting mechanism and a second supporting mechanism arranged downstream of the first conveyor belt, the second lifting mechanism is used to lift the empty material trays on the first conveyor belt, and the second supporting mechanism is used to insert into the bottom of the material tray and support at least one material tray.

[0015] Furthermore, the conveying mechanism also includes a rotating roller with suction holes and a second conveyor belt. The rotating roller is arranged between the conveying suction head and the second conveyor belt, and is used to suck the VC metal sheet on the conveying suction head and place it on the second conveyor belt after rotating it 180°. The second conveyor belt is used to move the VC metal sheet to the position of the pasting device.

[0016] Furthermore, the rotating roller is arranged at an upstream position of the second conveyor belt, an upstream end of the second conveyor belt faces the transport suction head, and a downstream end of the second conveyor belt faces the material pasting device.

[0017] Furthermore, the VC metal sheet laminating machine also includes a film tearing device, which includes a manipulator and a second driving mechanism. The manipulator is used to grab the protective film on the VC metal sheet, and the second driving mechanism is used to drive the manipulator to peel the protective film off the VC metal sheet. The moving direction of the manipulator has an angle with the VC metal sheet.

[0018] In summary, the embodiment of the present invention can stack multiple trays through the first supporting mechanism and the first lifting mechanism, and then provide the VC metal sheets on the trays to the material attaching device through the transport mechanism, and finally attach the VC metal sheets to the product through the material attaching device, so as to achieve efficient feeding effect, high degree of automation, high production efficiency and strong versatility.

[0019] The transport mechanism also includes a rotating roller with suction holes and a second conveyor belt. The rotating roller is set between the transport suction head and the second conveyor belt, and is used to suck the VC metal sheet on the transport suction head and rotate it 180 degrees before placing it on the second conveyor belt. The second conveyor belt is used to move the VC metal sheet to the position of the material attachment device. The VC metal sheet includes an adhesive surface that fits the product and a heat dissipation surface. When the VC metal sheet is placed in the tray, the adhesive surface or the heat dissipation surface may face up. The VC metal sheet can be turned 180 degrees by the rotating roller to change the upward surface as needed.

[0020] The transport mechanism also includes a second lifting mechanism and a second supporting mechanism disposed downstream of the first conveyor belt. The second lifting mechanism is used to lift the empty trays on the first conveyor belt, and the second supporting mechanism is used to insert into the bottom of the tray and support at least one tray. The second lifting mechanism and the second supporting mechanism are used to collect and stack the discarded trays after the VC metal sheets are taken away. When a certain number of trays are stacked, they are all taken away by a human or robot.

[0021] In addition, the VC metal sheet laminating machine also includes a film-tearing device, which includes a manipulator and a driving mechanism. The manipulator is used to grab the protective film on the VC metal sheet, and the driving mechanism is used to drive the manipulator to peel the protective film off the VC metal sheet. The moving direction of the manipulator and the VC metal sheet form an angle. The film-tearing device is used to tear off the protective film covering the adhesive surface of the VC metal sheet. Due to the high hardness of the protective film, the moving direction of the manipulator and the VC metal sheet form an angle, which facilitates the smooth removal of the protective film.

[0054] The following is a detailed description through specific embodiments:

[0055] The embodiment of the present invention provides a VC metal sheet bonding machine, comprising a frame 100 and a feeding device 200 and a bonding device 300 arranged on the frame;

[0056] like Figures 1 to 8 As shown, the feeding device 200 includes a conveying mechanism 210, a first lifting mechanism 220 and a first supporting mechanism 230. A plurality of trays (not shown in the figure) are stacked on the first lifting mechanism 220. After the first supporting mechanism 230 is inserted into the gap between the trays and supports some of the trays, the first lifting mechanism 220 moves the remaining trays to the conveying mechanism 210. The conveying mechanism 210 is used to provide the VC metal sheets in the remaining trays to the mounting device 300.

[0057] Specifically, the structure of the material tray is similar to a tray, with a groove in the middle for placing VC metal sheets (also called auxiliary materials). When multiple material trays are stacked together, there are gaps between the material trays for the insert 231 to be inserted therein and to hold up the upper material tray. The positions of the VC metal sheets in the material tray are generally the same (usually in the middle), so that the transport suction head 212 can be moved to a preset position to absorb the VC metal sheets.

[0058] like Figures 9 to 12 As shown, the attaching device 300 is used to attach the VC metal sheet provided by the feeding device 200 to the product.

[0059] like Figure 1 to Figure 2As shown, in this embodiment, the first lifting mechanism 220 includes a lifting tray 221, and the maximum lifting height of the lifting tray 221 is greater than the height of the first supporting mechanism 230. The first lifting mechanism 220 also includes a cylinder, which is arranged between the frame 100 and the lifting tray 221, and is used to drive the lifting tray 221 to move up and down along the Z axis. Multiple trays are stacked on the lifting tray 221 in sequence by gravity. Optionally, a suction head can also be provided on the bearing surface of the lifting tray 221 to absorb the bottom of the lowest tray, so that the tray is more stable and not easy to shake or fall.

[0060] The maximum lifting height of the lifting tray 221 is greater than the height of the first supporting mechanism 230. The beneficial effect of such a design is: after the first supporting mechanism 230 is inserted into the gap between the material trays and supports part of the material trays, the first lifting mechanism 220 moves the remaining material trays (usually one material tray) to the conveying mechanism 210; after the movement, there is a material tray on the conveying mechanism 210, there is no material tray on the first lifting mechanism 220, and multiple material trays are supported and placed on the first supporting mechanism 230. At this time, the first lifting mechanism 220 rises along the Z axis and lifts the multiple material trays again to a height exceeding the first supporting mechanism 230.

[0061] In this embodiment, the first supporting mechanism 230 includes an insert 231 and a first driving mechanism 232, and the first driving mechanism 232 is used to drive the insert 231 to extend or retract along the X-axis direction; the first supporting mechanism 230 is arranged next to the first lifting mechanism 220, and when the insert 231 extends to the bottom of the material tray, the first lifting mechanism 220 moves away from the material tray so that the insert 231 lifts the material tray; when the first lifting mechanism 220 moves to lift the material tray again so that the material tray is separated from the insert 231, the insert 231 retracts to move away from the material tray.

[0062] Specifically, the first driving mechanism 232 can be a cylinder, etc., for driving the insert 231 to move along the X axis. The insert 231 is a sheet, the thickness of which is smaller than the thickness of the gap between two trays, and is used to be inserted between the gaps of multiple trays stacked on the first lifting mechanism 220 .

[0063] For example, there are five trays stacked on the first lifting mechanism 220, and the cylinder drives the first lifting mechanism 220 to move to a preset height, so that the insert 231 is inserted between the lowest tray and the second to last tray; then the first lifting mechanism 220 moves downward, and at this time, only one tray on the first lifting mechanism 220 moves downward with the first lifting mechanism 220, and the insert 231 lifts the remaining trays. In this embodiment, there are two first support mechanisms 230, which are respectively arranged on both sides of the first lifting mechanism 220 and inserted from both sides of the X-axis of the tray. When the first lifting mechanism 220 descends to a height lower than the conveying mechanism 210, the tray on it is moved to the conveying mechanism 210 and removed, and then the first lifting mechanism 220 rises and lifts the remaining four trays again, and the insert 231 shrinks and leaves the tray. The first lifting mechanism 220 descends to the preset height again, so that the insert 231 is inserted between the lowest tray and the second to last tray, and a new round of work begins.

[0064] like Figure 2 As shown, in this embodiment, the feeding device 200 also includes a limiter 260, which is fixedly arranged beside the first supporting mechanism 230. The limiter 260 is in contact with the side of the material tray on the first supporting mechanism 230 to limit the displacement of the material tray. There is a gap between the limiter 260 and the conveying mechanism 210, and the gap is greater than or equal to the height of the material tray, so that the material tray on the conveying mechanism 210 can pass through the limiter 260. The shape and structure of the limiter 260 is a bent plate. Four limiters 260 are respectively arranged at the four corners of the material tray to limit the four directions of the material tray. The limiter 260 is also provided with a base. A row of openings for the base of the limiter 260 is provided on the frame 100. The position of the limiter 260 can be switched between multiple openings to adjust the distance between the limiters 260 to adapt to trays of different sizes.

[0065] Specifically, the position limiting member 260 is an "L" shaped baffle, and in this embodiment, four baffles are provided at four corners of the material tray to surround the material tray. The frame 100 is provided with a plurality of openings for adjusting the position of the position limiting member 260 to improve applicability.

[0066] Specifically, there is a gap between the stopper 260 and the first conveyor belt 211, and the gap is greater than or equal to the height of the tray, so that the tray on the first conveyor belt 211 can pass under the stopper 260. Figure 2As shown, the first conveyor belt 211 moves along the Y-axis from the lower left corner to the upper right corner, driving the material tray to move in the direction of the transport suction head 212; the gap between the two limit members 260 in the lower left corner of the Y-axis direction and the transport mechanism 210 is smaller than the height of the material tray, which is used to limit the material tray and prevent it from falling from the lower left corner; the gap between the two limit members 260 in the upper right corner of the Y-axis direction and the transport mechanism 210 is greater than or equal to the height of the material tray, which is used to allow the material tray to pass under the two limit members 260 under the drive of the first conveyor belt 211.

[0067] like Figure 3 As shown, in this embodiment, the positional relationship between the material tray and the first lifting mechanism 220 is set so that a part of the material tray is placed on and lifted by the first lifting mechanism 220, and the other part of the material tray is suspended in the air; when the first lifting mechanism 220 moves, the other part of the material tray is placed on and lifted by the conveying mechanism 210, and the material tray is separated from the first lifting mechanism 220.

[0068] In this embodiment, the transport mechanism 210 includes a first conveyor belt 211 and a transport suction head 212; the first conveyor belt 211 is arranged next to the first lifting mechanism 220, and the first lifting mechanism 220 moves the remaining part of the material tray to the first conveyor belt 211; the transport suction head 212 is used to suck the VC metal sheet in the material tray on the first conveyor belt 211 and move it to the pasting device 300.

[0069] Specifically, two first conveyor belts 211 are provided, which are respectively provided on both sides of the X-axis direction of the first lifting mechanism 220. When the first lifting mechanism 220 lifts a material tray and descends, the material tray falls on the first conveyor belt 211, and the first lifting mechanism 220 continues to move downward and leaves the material tray. The material tray moves along the Y-axis with the first conveyor belt 211 and moves away from the first lifting mechanism 220. After the first conveyor belt 211 drags the material tray away, the first lifting mechanism 220 rises again and lifts the remaining multiple material trays again. The insert 231 shrinks along the X-axis and leaves the material tray. The material tray is lifted by the first lifting mechanism 220 again and rises to a position that exceeds the height of the first supporting mechanism 230.

[0070] Specifically, the first conveyor belt 211 moves the material tray from the position of the first lifting mechanism 220 to the position of the transporting suction head 212 and stops, waiting for the transporting suction head 212 to suck and take away the VC metal sheet in the material tray, and then the first conveyor belt 211 continues to move the empty material tray to the position of the next second lifting mechanism 240.

[0071] Alternatively, if Figure 3As shown, in this embodiment, a sensor 215 can also be set along the first conveyor belt 211. The sensor 215 is set up beside the first conveyor belt 211, and the detection direction is upward along the Z axis to detect whether a material tray passes by. The sensor 215 can be an infrared sensor or a light sensor, and the material tray is recognized when it passes above the sensor 215.

[0072] like Figure 5 As shown, the transport suction head 212 is supported on the frame 100 by a gantry frame and is set on the first conveyor belt 211. The transport suction head 212 can move freely along the XYZ axis through a moving device. Optionally, the transport suction head 212 can also have a self-rotation design to better absorb the VC metal sheet.

[0073] like Figures 4 to 6 As shown, in this embodiment, the transport mechanism 210 also includes a second lifting mechanism 240 and a second supporting mechanism 250 arranged downstream of the first conveyor belt 211. The second lifting mechanism 240 is used to lift the empty material tray above the first conveyor belt 211, and the second supporting mechanism 250 is used to be inserted into the bottom of the material tray and support at least one material tray.

[0074] Specifically, the structures and working principles of the second lifting mechanism 240 and the second supporting mechanism 250 are the same as those of the first lifting mechanism 220 and the first supporting mechanism 230, and are symmetrically distributed. The second lifting mechanism 240 first descends along the Z axis to below the surface of the first conveyor belt 211, and the second supporting mechanism 250 contracts. When the first conveyor belt 211 moves the empty tray to above the second lifting mechanism 240, the second lifting mechanism 240 rises and lifts the tray to a height exceeding the second supporting mechanism 250, and the second supporting mechanism 250 extends below the tray. The second lifting mechanism 240 descends to make the tray fall on the second supporting mechanism 250, completing the function of collecting the empty tray.

[0075] like Figures 7 and 8 As shown, in this embodiment, the transport mechanism 210 further includes a rotating roller 213 (such as Figure 7 and Figure 8 Due to the angle, the suction hole is not visible. Fig.11 and Fig.12 Suction holes can be seen) and a second conveyor belt 214, a rotating roller 213 is set between the transport suction head 212 and the second conveyor belt 214, and is used to suck the VC metal sheet on the transport suction head 212 and place it on the second conveyor belt 214 after rotating it 180°. The second conveyor belt 214 is used to move the VC metal sheet to the position of the pasting device 300.

[0076] Specifically, the VC metal sheet is a sheet with an adhesive surface and a working surface. The adhesive surface is used to contact the product and stick to the product, and the working surface is used to face away from the product to achieve heat dissipation and other functions. A protective film will be attached to the adhesive surface in advance. Before the VC metal sheet is attached to the product, the protective film must be torn off first.

[0077] There are two situations when the VC metal sheet is placed in the material tray, one is with the adhesive surface facing up, and the other is with the adhesive surface facing down. When the adhesive surface faces down, the transport suction head 212 sucks the upward working surface and directly places it on the second conveyor belt 214, and the auxiliary material suction head 350 also sucks the working surface, and after the film tearing device 400 tears the film, the auxiliary material suction head 350 sticks the adhesive surface facing down on the product. When the adhesive surface faces up, the transport suction head 212 sucks the upward adhesive surface (at this time, there is still a protective film on the adhesive surface), places it on the suction hole of the rotating roller 213, rotates 180°, and then places it on the second conveyor belt 214, and the auxiliary material suction head 350 also sucks the working surface, and after the film tearing device 400 tears the film, the auxiliary material suction head 350 sticks the adhesive surface facing down on the product.

[0078] Specifically, in this embodiment, a sensor 215 is further included. The sensor 215 is mounted on the second conveyor belt 214, and the detection direction is toward the second conveyor belt 214, and is used to detect whether a VC metal sheet passes through. The sensor 215 can be an infrared sensor or a light sensor, and the VC metal sheet is identified when it passes over the sensor 215. Optionally, when the sensor 215 is a camera, etc., it can also be used to detect whether the rotating roller 213 correctly turns the adhesive side of the VC metal sheet downward.

[0079] In this embodiment, the rotating roller 213 is arranged at the upstream position of the second conveyor belt 214 , the upstream end of the second conveyor belt 214 faces the transport suction head 212 , and the downstream end of the second conveyor belt 214 faces the pasting device 300 .

[0080] Specifically, the second conveyor belt 214 is used to move the VC metal sheet provided by the transport suction head 212 to the auxiliary material pasting suction head 350 of the pasting device 300 for suction.

[0081] like Figures 9 to 12As shown, in this embodiment, the material pasting device 300 further includes an assembly line 310, a guide mechanism 320, a feeding suction head 330, a second conveyor belt 214, a feeding suction head 350, and a feeding suction head 360. The assembly line 310 is used to move the product to be pasted with auxiliary materials (i.e., VC metal sheets) along the Y axis to the guide mechanism 320, the guide mechanism 320 is used to guide the product to the bottom of the feeding suction head 330, the feeding suction head 330 is used to transport the product to the third conveyor belt 340, the third conveyor belt 340 is used to move the product to the bottom of the feeding suction head 350 that has sucked the VC metal sheet, so that the feeding suction head 350 can paste the auxiliary materials, and after the auxiliary materials are pasted, the third conveyor belt 340 continues to move the product to the bottom of the feeding suction head 360, and the feeding suction head 360 is used to move the product pasted with auxiliary materials back to the assembly line 310 and move it to the next process.

[0082] like Fig.11 As shown, the top of the guide mechanism 320 can be bent to form an opening for guiding the product to move to a preset position. The loading suction head 330 can move along the Z axis or the X axis, and is used to suck the product at the preset position of the guide mechanism 320 and move it to the third conveyor belt 340. The third conveyor belt 340 can move the product along the Y axis. The auxiliary material sticking suction head 350 can move along the X, Y, and Z axes, and is used to suck the VC metal sheet on the second conveyor belt 214, move it to the film tearing device 400 to tear the film, and then move it to the product on the third conveyor belt 340 to stick the VC metal sheet, and repeatedly move it back to the second conveyor belt 214 to start the next round of work. The unloading suction head 360 can move along the Z axis or the X axis, and is used to suck the product on the third conveyor belt 340 with the VC metal sheet stuck on it and move it back to the assembly line 310.

[0083] Alternatively, if Fig. 9 As shown, the third conveyor belt 340 is divided into three sections, which are the first section, the second section, and the third section from left to right along the Y axis. The loading suction head 330 moves the product to be attached with the VC metal sheet to the first section, the auxiliary material attachment suction head 350 attaches the VC metal sheet to the product in the second section, and the unloading suction head 360 moves the product after the VC metal sheet is attached from the third section back to the assembly line 310. The three-section design has the advantage that the products in the three positions can be moved more flexibly and more efficiently. For example, when the product in the third section is waiting to be sucked by the unloading suction head 360, the product in the first section can be moved to the second section at the same time, and it is not necessary to wait for the product in the third section to be sucked by the unloading suction head 360 before moving the product in the first section like the traditional whole conveyor belt.

[0084] like Figures 9 to 12As shown, in this embodiment, it also includes a positioning device 500 before taking auxiliary materials, a positioning device 600 after taking auxiliary materials, and a positioning device 700 for attaching auxiliary materials. The positioning device 500 before taking auxiliary materials is set to align with the second conveyor belt 214 downward along the Z axis, and is used to position the VC metal sheet on the second conveyor belt 214, so that the auxiliary material attaching suction head 350 can absorb the VC metal sheet on the second conveyor belt 214. The positioning device 600 after taking auxiliary materials is set to align with the auxiliary material attaching suction head 350 upward along the Z axis, and is used to position the VC metal sheet on the auxiliary material attaching suction head 350. After calibration and correction, it is convenient for the auxiliary material attaching suction head 350 to attach more accurately. The positioning device 700 for attaching auxiliary materials is set to align with the third conveyor belt 340 downward along the Z axis, and is used to position the product on the third conveyor belt 340. Combined with the information of the positioning device 600 after taking auxiliary materials, the position of the VC metal sheet is more accurate. Optionally, the auxiliary material positioning device 700 can also re-check whether the position of the VC metal sheet on the product is properly attached after the VC metal sheet is attached and the auxiliary material suction head 350 is removed, thereby realizing the function of quality inspection.

[0085] like Fig.13 and Fig.14 As shown, in this embodiment, the VC metal sheet laminating machine also includes a film tearing device 400, which includes a manipulator 410 and a second driving mechanism 420. The manipulator 410 is used to grab the protective film on the VC metal sheet, and the second driving mechanism 420 is used to drive the manipulator 410 to peel the protective film off the VC metal sheet. The moving direction of the manipulator 410 has an angle with the VC metal sheet.

[0086] Specifically, the film tearing device 400 also includes a collection box 430, which is arranged below the manipulator 410. After tearing off the protective film, the manipulator 410 moves to the top of the collection box 430 and releases it, so that the protective film falls into the collection box 430 to collect waste. The second driving mechanism 420 pushes the manipulator 410 to move through two inclined rods. The moving direction of the manipulator 410 is at an angle with the VC metal sheet (that is, at an angle with the XY plane). Since the protective film is hard and difficult to bend, the angle is designed to avoid shaking as much as possible when tearing the film, which affects the position of the VC metal sheet on the auxiliary material suction head 350. At the same time, the design of the angle makes it easy to tear off the protective film. If it is torn horizontally along the Y-axis direction, the protective film is too hard to peel off and is more likely to hit the VC metal sheet.

[0087] In summary, the embodiment of the present invention can stack multiple trays through the first supporting mechanism 230 and the first lifting mechanism 220, and then provide the VC metal sheets on the trays to the material attaching device 300 through the conveying mechanism 210, and finally attach the VC metal sheets to the product through the material attaching device 300. Efficient feeding effect is achieved, and the degree of automation, production efficiency and versatility are high.

[0088] The transport mechanism 210 also includes a rotating roller 213 with suction holes and a second conveyor belt 214. The rotating roller 213 is disposed between the transport suction head 212 and the second conveyor belt 214, and is used to absorb the VC metal sheet on the transport suction head 212 and rotate it 180° before placing it on the second conveyor belt 214. The second conveyor belt 214 is used to move the VC metal sheet to the position of the material attaching device 300. The VC metal sheet includes an adhesive surface that fits the product and a heat dissipation surface. When the VC metal sheet is placed in the tray, the adhesive surface or the heat dissipation surface may face upward. The VC metal sheet can be turned 180° by the rotating roller 213 to change the upward surface as needed.

[0089] The transport mechanism 210 further includes a second lifting mechanism 240 and a second supporting mechanism 250 disposed downstream of the first conveyor belt 211. The second lifting mechanism 240 is used to lift the empty trays on the first conveyor belt 211, and the second supporting mechanism 250 is used to insert into the bottom of the trays and support at least one tray. The second lifting mechanism 240 and the second supporting mechanism 250 are used to collect and stack the discarded trays after the VC metal sheets are taken away. When a certain number of trays are stacked, they are all taken away manually or by a device such as a robot 410.

[0090] The VC metal sheet laminating machine further includes a film-tearing device 400, which includes a manipulator 410 and a driving mechanism. The manipulator 410 is used to grab the protective film on the VC metal sheet, and the driving mechanism is used to drive the manipulator 410 to peel the protective film off the VC metal sheet. The moving direction of the manipulator 410 is at an angle to the VC metal sheet. The film-tearing device 400 is used to tear off the protective film covering the adhesive surface of the VC metal sheet. Due to the high hardness of the protective film, the moving direction of the manipulator 410 is at an angle to the VC metal sheet, which facilitates the smooth peeling of the protective film.

[0091] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
