Description

Technical Field

[0001] The present application relates to the technical field of glue removal, and in particular to a glue removal device. Background Art

[0002] There are two existing methods for removing protective glue from the surface of workpieces. The first method is to soften the protective glue with an organic solvent with high alkalinity and high solvent content and then remove it. The second method is to use a manual method to manually wipe the protective glue with an organic solvent such as alcohol to remove the protective glue. However, in the first method, the high alkalinity and high solvent content agent will pollute the environment and corrode the workpiece. The second method has the problem of low manual efficiency and a high risk of bruising and scratching the workpiece. Utility Model Content

[0003] In view of the above, it is necessary to propose a degumming equipment with low environmental pollution, no corrosion to the workpiece, high degumming efficiency and low risk of workpiece scratching.

[0004] An embodiment of the present application provides a degumming device. The degumming device includes a conveyor belt that carries and conveys the workpiece to be degummed, and a spray assembly and a shower assembly that are sequentially arranged along the conveying direction of the conveyor belt. The spray assembly is located above the conveyor belt. The shower assembly is located above and / or below the conveyor belt. The conveyor belt drives the workpiece to be degummed to pass through the spray assembly and the shower assembly in sequence. When the workpiece to be degummed passes through the spray assembly, the spray assembly sprays a water flow with a first pressure to the workpiece to be degummed to remove part of the glue layer of the workpiece to be degummed. When the workpiece to be degummed passes through the shower assembly, the shower assembly sprays a water flow with a second pressure to the workpiece to be degummed to remove the remaining glue layer of the workpiece to be degummed, and the second pressure is less than the first pressure.

[0005] In the degumming equipment of the embodiment of the present application, when the workpiece to be degummed is conveyed by the conveyor belt to the station corresponding to the spray assembly, the strong impact force generated by the water flow with the first pressure sprayed by the spray assembly can cut, crush and peel off the glue layer on the surface of the workpiece, so as to remove the large area of ​​glue with strong adhesion on the surface of the workpiece. When the workpiece to be degummed is conveyed by the conveyor belt to the station corresponding to the spray assembly, the water flow with the second pressure sprayed by the spray assembly can remove the small area of ​​residual broken glue on the surface of the workpiece, so as to achieve the effect of complete degumming. It can be seen that the degumming equipment of the embodiment of the present application, in the degumming process, uses water as the medium, and uses the water flow with the first pressure and the water flow with the second pressure to remove the glue layer on the surface of the workpiece. No chemical agents are used in the process, there is no corrosion to the workpiece, and there is almost no environmental pollution. Moreover, the degumming equipment has a certain degree of automation, which is beneficial to improve efficiency and reduce the risk of scratching the workpiece compared to the manual wiping method.

[0026]

[0027] The following specific implementation manner will further illustrate the embodiments of the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0029] like Figure 1As shown, the degumming equipment 100 of one embodiment of the present application includes a spray mechanism 10, a shower mechanism 20, an air knife mechanism 30 and a conveying mechanism 40. The conveying mechanism 40 includes a conveyor belt 41 that carries and conveys the workpiece P to be degummed. The spray mechanism 10, the shower mechanism 20, and the air knife mechanism 30 are sequentially arranged along the conveying direction of the conveyor belt 41. For the convenience of description below, the conveying direction of the conveyor belt 41 is defined as the first direction D1, the direction from the bottom of the conveyor belt 41 to the top of the conveyor belt 41 is defined as the second direction D2, and the width direction of the conveyor belt 41 is defined as the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0030] During the debonding process, the conveyor belt 41 drives the workpiece P to be debonded to pass through the spray mechanism 10, the shower mechanism 20, and the air knife mechanism 30 in sequence. Therefore, the workstations corresponding to the spray mechanism 10, the shower mechanism 20, and the air knife mechanism 30 are hereinafter referred to as the first workstation 110, the second workstation 120, and the third workstation 130, respectively.

[0031] Specifically, when the conveyor belt 41 drives the workpiece P to be debonded to pass through the spray mechanism 10, the spray mechanism 10 sprays a water flow with a first pressure to the workpiece P to be debonded to remove part of the adhesive layer of the workpiece P to be debonded. When the conveyor belt 41 drives the workpiece P to be debonded to pass through the spray mechanism 20, the spray mechanism 20 sprays a water flow with a second pressure to the workpiece P to be debonded to remove the remaining adhesive layer of the workpiece P to be debonded. When the conveyor belt 41 drives the workpiece P to be debonded to pass through the air knife mechanism 30, the air knife mechanism 30 blows air to the workpiece P to be debonded located at the third station 130 to remove water droplets on the workpiece P to be debonded.

[0032] More specifically, the pressure of the water flow emitted by the injection mechanism 10 is greater than that of the water flow emitted by the spray mechanism 20, that is, the first pressure is greater than the second pressure. In this way, when the workpiece P to be debonded passes through the injection mechanism 10, the water flow with the first pressure is conducive to removing the large-area adhesive with strong adhesion of the workpiece P to be debonded. When the workpiece P to be debonded passes through the spray mechanism 20, the water flow with the second pressure is conducive to removing the small-area adhesive residue of the workpiece P to be debonded.

[0033] The degumming device 100 of the embodiment of the present application uses water as a medium to remove the glue layer of the workpiece P to be degummed, that is, the degumming device 100 does not use chemical agents during the degumming process, does not corrode the workpiece body, and is conducive to reducing pollution to the environment. Moreover, the degumming device 100 has a certain degree of automation, which is conducive to improving efficiency and reducing the risk of scratching the workpiece compared to the manual wiping method.

[0034] The following combination Figures 2 to 5 The situation when the workpiece P to be debonded is transferred to the first station 110 is described in detail. Figure 2As shown, a jig J is installed above the conveyor belt 41, and a plurality of workpieces P to be debonded are placed on each jig J. Figure 2 Two jigs J are shown schematically. In the present embodiment, three workpieces P to be debonded are placed on each jig J at intervals along the first direction D1, and four workpieces P to be debonded are placed at intervals along the third direction D3. Each jig J includes a frame F that is roughly rectangular and annular, a first support portion S1 connected to the frame F and extending along the third direction D3, and a second support portion S2 connected to the frame F and extending along the first direction D1. The plurality of first support portions S1 are spaced apart along the first direction D1, and the plurality of second support portions S2 are spaced apart along the third direction D3. Each workpiece P to be debonded is located above the jig J, and is located at the intersection of a first support portion S1 and a second support portion S2. In other embodiments, the number of workpieces P to be debonded placed in each jig J, as well as the specific structure of the jig J, can be adjusted according to actual needs, and are not limited to Figure 2 The situation of the embodiment shown.

[0035] like Figure 3 As shown, the workpiece P to be debonded includes a workpiece body B and a glue layer A located on the workpiece body B. The workpiece body B is, for example, a mobile phone middle frame. Specifically, the workpiece body B includes a first surface B1 and a second surface B2 opposite to each other and a plurality of side surfaces B3 connecting the first surface B1 and the second surface B2. Figure 2 and Figure 3 , the number of the side surfaces B3 is four, and the adhesive layer A covers the first surface B1 and the four side surfaces B3. After the workpiece P to be debonded is placed on the jig J, the adhesive layer A on the first surface B1 faces away from the multiple first support portions S1 and the multiple second support portions S2. The adhesive layer A on the first surface B1 and the adhesive layer A on the side surfaces B3 are completely exposed. In other embodiments, the adhesive layer A may cover at least one of the first surface B1 and the multiple side surfaces B3, but is not limited to the above.

[0036] The spray mechanism 10 includes a spray assembly 11 located above the conveyor belt 41. It is understandable that the spray mechanism 10 may also include a water storage device (such as a water storage tank) for providing a water source for the spray assembly 11, and the spray assembly 11 is connected to the water storage device. Specifically, the spray assembly 11 includes a first spray assembly 111 and a second spray assembly 112 arranged at intervals along the conveying direction of the conveyor belt 41. The first spray assembly 111 and the second spray assembly 112 are both located above the conveyor belt 41. The first spray assembly 111 includes a first connecting rod R1 extending along a third direction D3 and a plurality of first nozzles N1 arranged on the first connecting rod R1 at intervals along the third direction D3.

[0037] In addition, the first spray assembly 111 further includes a first driving mechanism 1111 connected to the first connecting rod R1. The first driving mechanism 1111 drives the first connecting rod R1 to reciprocate along the third direction D3 to drive the plurality of first nozzles N1 to reciprocate along the third direction D3. At the same time, each first nozzle N1 can spray a water flow of a first pressure to the plurality of workpieces P to be debonded located thereunder. In this way, by driving the plurality of first nozzles N1 to reciprocate along the third direction D3 through the first driving mechanism 1111, water can be repeatedly sprayed to the plurality of workpieces P to be debonded along the third direction D3, which is conducive to improving the efficiency of debonding.

[0038] Specifically, the first driving mechanism 1111 can be a linear guide driving mechanism, which includes a first guide rail 1111a, a first slider 1111b that cooperates with the first guide rail 1111a and is connected to the first connecting rod R1 at the bottom, and a first servo motor (not shown) that is connected to the first slider 1111b and drives the first slider 1111b to reciprocate along the third direction D3 on the first guide rail 1111a.

[0039] Similarly, the second spray assembly 112 includes a second driving mechanism 1121, a second connecting rod R2 connected to the second driving mechanism 1121 and extending along the third direction D3, and a plurality of second nozzles arranged on the second connecting rod R2 at intervals along the third direction D3. The second driving mechanism 1121 drives the second connecting rod R2 to reciprocate along the first direction D1, thereby driving the plurality of second nozzles N2 to reciprocate along the first direction D1. At the same time, each second nozzle N2 can spray a water flow of a first pressure to a plurality of workpieces P to be debonded located below it. In this way, by driving the plurality of second nozzles N2 to reciprocate along the first direction D1 through the second driving mechanism 1121, water can be repeatedly sprayed in the first direction D1 to the workpieces P to be debonded located on the first station 110 to be debonded, thereby improving the efficiency of debonding.

[0040] Specifically, the second driving mechanism 1121 can be a linear guide driving mechanism, which includes a second guide rail 1121a, a second slider 1121b that cooperates with the second guide rail 1121a and is connected to the second connecting rod R2 at the bottom, and a second servo motor (not shown) connected to the second slider 1121b and drives the second slider 1121b to reciprocate along the first direction D1 on the second guide rail 1121a.

[0041] In some embodiments, the first pressure ranges from 30MPa to 50MPa (e.g., 30MPa to 35MPa, 35MPa to 40MPa, 40MPa to 45MPa, or 45MPa to 50MPa). Specifically, if the first pressure range is less than the lower limit, the water flow has insufficient cutting, crushing, and peeling ability on the adhesive layer A, and the adhesive removal effect is poor, and if the first pressure range is greater than the upper limit, the water flow may damage the surface of the workpiece. In particular, when the surface of the workpiece is a composite material, if the first pressure range is greater than the upper limit, the water flow is likely to damage the composite material.

[0042] like Figure 4 As shown, in this embodiment, along the third direction D3, the first spray assembly 111 is provided with twelve first nozzles N1, and every three first nozzles N1 correspond to one workpiece P to be debonded. In this way, along the third direction D3, the first spray assembly 111 can simultaneously debond four workpieces P to be debonded, which is beneficial to improve the efficiency of debonding. In other embodiments, the number and arrangement of the first nozzles N1 in the first spray assembly 111 are not limited to the above. Similarly, along the third direction D3, in the second spray assembly 212, a plurality of second nozzles N2 can correspond to one workpiece P to be debonded, and the second spray assembly 212 can simultaneously debond at least four workpieces P to be debonded, which is beneficial to improve the efficiency of debonding.

[0043] like Figure 5 As shown, the spray angle of each first nozzle N1 is adjustable. In this way, the first nozzle N1 can spray water at multiple angles to the workpiece P to be debonded, so as to facilitate the directional stripping of the glue layer A on the surface of the workpiece, thereby facilitating the removal of residual glue on the surface of the workpiece without dead angles and all-round purification. Similarly, the spray angle of each second nozzle N2 is adjustable. In this way, the second nozzle N2 can spray water at multiple angles to the workpiece P to be debonded, so as to facilitate the directional stripping of the glue layer A on the surface of the workpiece, thereby facilitating the removal of residual glue on the surface of the workpiece without dead angles and all-round purification.

[0044] In some embodiments, after the workpiece P to be debonded passes through the spray mechanism 10 at the first station 110, a large area of ​​the adhesive layer is broken and peeled off, but a small area of ​​the adhesive layer with low adhesion still remains. Thereafter, the workpiece P to be debonded can be conveyed from the first station 110 to the spray mechanism 20 corresponding to the second station 120 via the conveyor belt 41. Figure 6As shown, the spray mechanism 20 includes a spray assembly 21 (i.e., a first spray assembly 211) located below the conveyor belt 41 and a spray assembly 21 (i.e., a second spray assembly 212) located above the conveyor belt 41. It is understandable that the spray mechanism 20 may also include another water storage device (not shown) that provides a water source for the spray assembly 21, and the spray assembly 21 is connected to the other water storage device. The spray mechanism 10 and the spray mechanism 20 may also share the same water storage device, or be connected to the same water pump, etc., without limitation to the above.

[0045] Please refer to Figure 6 and Figure 7 The first spray assembly 211 includes a first connecting pipe C1 located below the conveyor belt 41, a plurality of first spray pipes T1 connected to the first connecting pipe C1, and a plurality of third nozzles N3 connected to each first spray pipe T1. The second spray assembly 212 includes a second connecting pipe C2 located above the conveyor belt 41, a plurality of second spray pipes T2 connected to the second connecting pipe C2, and a plurality of fourth nozzles N4 connected to the second spray pipes T2. The third nozzle N3 and the fourth nozzle N4 are used to spray a water flow of a second pressure to the workpiece P to be debonded.

[0046] Specifically, Figure 6 Schematically illustrates two first connection pipes C1 spaced apart along the first direction D1 and two second connection pipes C2 spaced apart along the first direction D1, but the present invention is not limited thereto. Figure 7 A first connecting pipe C1 is connected to six first nozzles T1, and one end of each first nozzle T1 is connected to a third nozzle N3; a second connecting pipe C2 is connected to six second nozzles T2, and one end of each second nozzle T2 is connected to a fourth nozzle N4. The two opposite surfaces and four side surfaces of each workpiece P to be debonded can be sprayed by the water flow sprayed by two third nozzles N3 and two fourth nozzles N4 at the same time. In this way, by respectively arranging the first spray assembly 211 and the second spray assembly 212 on the opposite sides of the conveyor belt 41, it is beneficial to ensure the spray effect of the workpiece P to be debonded, so as to maximize the removal of the residual glue layer A on the workpiece P to be debonded.

[0047] In some embodiments, the second pressure ranges from 3 MPa to 5 MPa (e.g., 3 MPa to 3.5 MPa, 3.5 MPa to 4 MPa, 4 MPa to 4.5 MPa, or 4.5 MPa to 5 MPa). Specifically, if the second pressure range is less than the lower limit, the water flow has insufficient stripping ability for the residual glue and the glue removal effect is poor, and if the second pressure range is greater than the upper limit, the water flow may damage the surface of the workpiece.

[0048] In some embodiments, the first connecting tube C1 and the second connecting tube C2 are both universal tubes. In this way, the angle of the injection end of the third nozzle N3 can be adjusted through the first connecting tube C1, and the angle of the injection end of the fourth nozzle N4 can be adjusted through the second connecting tube C2, so as to flexibly adjust the injection position for different workpieces, thereby eliminating the debonding dead angle. In other embodiments, the first connecting tube C1 and the second connecting tube C2 are not limited to being universal tubes.

[0049] In some embodiments, the injection end of the third nozzle N3 and the injection end of the fourth nozzle N4 are both flat. Specifically, the injection end of the third nozzle N3 and the injection end of the fourth nozzle N4 are both fan-shaped. The flat injection end can make the coverage of the third nozzle N3 or the fourth nozzle N4 wider, thereby improving the degumming effect. In other embodiments, the shapes of the injection end of the third nozzle N3 and the injection end of the fourth nozzle N4 are not limited to being flat.

[0050] In some embodiments, after the workpiece P to be debonded passes through the spray mechanism 20 , a small area of ​​residual adhesive is removed. At this time, the workpiece P to be debonded can be conveyed to the air knife mechanism 30 corresponding to the third station 130 via the conveyor belt 41 .

[0051] like Figure 8 As shown, the wind knife mechanism 30 includes a wind knife 31 and a bracket 33 for supporting and fixing the wind knife 31. The bracket 33 is located on opposite sides of the conveyor belt 41 in the third direction D3, and the wind knife 31 is arranged above the conveyor belt 41. Fig. 9 As shown, when the workpiece P to be debonded passes through the air knife 31, the air knife 31 can blow air toward the workpiece P to be debonded to remove water droplets on the surface of the workpiece P. It can be understood that at this time, the adhesive layer A on the workpiece P to be debonded has been basically removed after passing through the spray mechanism 10 and the spray mechanism 20, and the air blown by the air knife 31 basically removes the water droplets on the surface of the workpiece body B itself.

[0052] In some embodiments, the wind knife 31 is an integrated molding structure to ensure uniform air output.

[0053] In some embodiments, at least one of the height of the wind knife 31 relative to the conveyor belt 41, the wind direction of the wind knife 31, and the wind force of the wind knife 31 is adjustable to improve process flexibility. In other embodiments, the structure and function of the wind knife 31 are not limited to the above.

[0054] In other embodiments, the adhesive removal equipment 100 may not include the air knife mechanism 30, so that the surface of the workpiece can be dried naturally.

[0055] In summary, the degumming equipment of the embodiment of the present application uses water as a medium during the degumming process, and adopts a combination of a water flow with a first pressure and a water flow with a second pressure to remove the glue layer of the workpiece to be degummed. No chemical agents are used during the degumming process, and there is no corrosion to the workpiece body, which helps to reduce pollution to the environment. Moreover, the degumming equipment of the embodiment of the present application has a certain degree of automation. Compared with the manual wiping method, it is beneficial to improve efficiency and reduce the risk of scratches on the workpiece to be degummed. In addition, in the degumming equipment of the embodiment of the present application, the water in the injection mechanism and the spray mechanism can also be filtered and recycled, and the water resource consumption is small.

[0056] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
