Description

Technical Field

[0001] The utility model relates to production and processing equipment in the field of 3C, in particular to a release paper peeling device suitable for 3C product processing. Background Art

[0002] In the manufacturing process of 3C products (such as laptops, tablets, mobile phones, smart watches, smart bracelets, etc.), release paper is used in many links, so it is often necessary to tear off the release paper. One existing method is manual tearing, which has a low degree of automation, resulting in low operating efficiency and easy to cause damage to the product, thus affecting the quality of the product.

[0003] In order to solve the problems caused by manual tearing, a special peeling paper device has appeared in the prior art. Generally speaking, the ends of the release paper are clamped by matching upper and lower clamping parts, and then the release paper is torn off by pulling in the horizontal and vertical directions. This peeling paper device is mainly suitable for the case where the release paper is large and can protrude from the end of the product.

[0004] However, in the manufacturing process of 3C products, release paper is usually required when assembling other corresponding components at the mounting holes of some components, and the release paper also needs to be torn off after the assembly is completed. The release paper used in or around the mounting holes is usually small in size, so the existing release paper tearing device cannot clamp the end of this type of release paper, and the release paper in or around the mounting holes cannot be torn off using the existing clamping type device. At present, the release paper at the mounting holes is still torn off manually, especially when the diameter of the mounting holes is small, it can only be torn off manually one by one, which not only has low operating efficiency, but also has high labor intensity, resulting in high production costs of the products.

[0005] Therefore, it is necessary to provide a device that can quickly and automatically tear off the release paper used for the product installation hole position to solve the above problems. Utility Model Content

[0034] Combine first Figure 1-Figure 12 As shown, the release paper peeling device 100 provided by the present invention is particularly suitable for peeling release paper from a product 200 having a mounting hole 210. However, the present invention is not limited thereto and can also be used for peeling release paper from other products.

[0035] Continue to combine Figure 1-Figure 12 As shown, in one embodiment of the utility model, the release paper peeling device 100 includes a product fixing part 110, a peeling drive assembly 120 and a vacuum adsorption assembly 140. The product fixing part 110 is fixedly arranged and used to position the product 200 with release paper. The peeling drive assembly 120 is installed above the product fixing part 110, and the peeling drive assembly 120 includes a driving part 121 and a pressing punch 122 connected to the lower end of the driving part 121, and the driving part 121 is used to drive the pressing punch 122 to extend and retract. The vacuum adsorption assembly 140 includes an adsorption tube 141 and a vacuum generator (not shown) connected to the adsorption tube 141, and the adsorption tube 141 is docked at the bottom of the product fixing part 110. Therefore, the driving member 121 drives the pressing punch 122 to extend downward and press down the release paper on the product 200, so that the release paper is separated from the product 200, and the release paper is peeled off, and then the negative pressure generated by the vacuum generator sucks out the release paper separated from the product 200. This method can quickly peel the release paper off the product 200, and is particularly suitable for peeling the release paper at the position of the mounting hole 210 on the product 200, which can significantly improve the efficiency of peeling the release paper.

[0036] In the present invention, the driving member is preferably a cylinder, but is not limited thereto, and other power components may also be selected.

[0037] Continue to combine Figure 1-Figure 12 As shown, in a preferred embodiment of the present invention, the release paper peeling device 100 further includes a suction guide 130, which is arranged between the product fixing member 110 and the adsorption tube 141, and the suction guide 130 is provided with a suction channel 131 running through the upper and lower ends thereof, and the suction channel 131 is in a structure of being larger at the top and smaller at the bottom, and the suction channel 131 is sealed and butted with the adsorption tube 141, as shown in FIG. Fig. 9 The arrangement of the suction channel 131 allows the peeled release paper to be quickly sucked into the adsorption tube 141 under a relatively small vacuum negative pressure, thereby realizing rapid recovery of the release paper.

[0038] Continue to combine Figure 1-Figure 12 As shown, in the present invention, the release paper peeling device 100 also includes a mounting seat 150, and the mounting seat 150 includes at least one top plate 151 and a stand 152 fixed to the top plate 151. The structure of the stand 152 is a conventional structure in the art and will not be described in detail. The product fixing member 110 is fixed on the top plate 151 and is opposite to the stand 152. The driving member 121 of the peeling driving assembly 120 is fixed on the stand 152, and the pressing punch 122 at the lower end thereof protrudes downward. The suction guide 130 is fixed below the top plate 151, and the suction channel 131 is directly opposite to the mounting hole 210 on the product 200, so that the release paper peeled from the mounting hole 210 can fall into the suction channel 131. The vacuum adsorption assembly 140 is sealingly connected to the lower end of the suction guide 130.

[0039] Combine the following Figure 7-Figure 9 As shown, in one embodiment of the present invention, the top plate 151 is provided with a second through hole 1511 (see Figure 7 ), the shape and size of the second through hole 1511 preferably correspond to the upper end of the suction channel 131. When the suction guide 130 is fixed below the top plate 151, the second through hole 1511 corresponds to the suction channel 131 up and down and is sealedly connected, that is, the suction guide 130 and the top plate 151 are sealed. Fig. 9 The release paper peeled off from the mounting hole 210 enters the suction channel 131 below through the second through hole 1511 .

[0040] Combine the following Figure 2-4 , Figure 7-9As shown, in a preferred embodiment, the mounting seat 150 further includes a bottom plate 153 and a plurality of supporting side plates 154, the bottom plate 153 is arranged below the top plate 151 and the two are connected by a plurality of supporting side plates 154. In this embodiment, the top plate 151 and the bottom plate 153 are connected by four supporting side plates 154, so that a containing space is formed between the bottom plate 153 and the top plate 151. The suction guide 130 is accommodated in the containing space and fixed to the top plate 151 and / or the bottom plate 153, and the suction guide 130 is sealed and connected to the top plate 151, as shown in FIG. Figure 3-4 , Figure 8-9 The vacuum adsorption assembly 140 is installed below the bottom plate 153. Specifically, the adsorption tube 141 is passed through the bottom plate 153, and the top end of the adsorption tube 141 is connected to the suction channel 131. Fig. 9 As shown, the adsorption tube 141 is sealedly connected to the suction guide 130 and the bottom plate 153.

[0041] It is understandable that the mounting seat 150 is not limited to the structural setting in the present embodiment, and it is also feasible to set it as other structures.

[0042] Continue to combine Figure 2-4 , Figure 7-9 As shown, in a preferred embodiment, the vacuum adsorption assembly 140 further includes a box body 142, which is fixed below the bottom plate 153, and the adsorption tube 141 is accommodated in the box body 142, and the upper end of the adsorption tube 141 is passed through the bottom plate 153 and connected to the suction guide 130, and the lower end of the adsorption tube 141 passes through the bottom of the box body 142 to connect the vacuum generator, as shown in FIG. Fig. 9 shown.

[0043] Combine the following Figure 2-3 , Figure 6-7 , Fig.10 As shown, in one embodiment of the utility model, the product fixing part 110 is in the shape of a plate, and a card slot 111 for clamping the product 200 is opened on the product fixing part 110. The shape of the card slot 111 corresponds to the shape of the product 200, so that the product 200 can be pressed into the card slot 111 to fix the product 200, which is convenient for peeling off the release paper on the product 200, and the product 200 can be quickly clamped in and out before and after peeling, which is beneficial to improving production efficiency.

[0044] In this embodiment, a first through hole 112 is further provided through the card slot 111, that is, a first through hole 112 is provided on the bottom plate of the product fixing member 110, and the opening position of the first through hole 112 corresponds to the position of the release paper on the product 200. At the same time, when the product fixing member 110 is fixed on the top plate 151 of the mounting seat 150, the first through hole 112 thereon corresponds to the second through hole 1511 on the top plate 151, so that the release paper peeled off from the bottom of the product 200 can be sucked into the suction guide 130 and the adsorption tube 141 through the first through hole 112 and the second through hole 1511, thereby realizing the recovery of the release paper.

[0045] Continue to view Figure 6-7 , Fig.10 , Fig.12 As shown, in a preferred embodiment, it is mainly used to peel off the release paper of the product 200 having multiple mounting holes 210. Therefore, a plurality of first through holes 112 are provided on the bottom plate 153 of the product fixing member 110, and the layout of the plurality of first through holes 112 corresponds to each mounting hole 210 on the product 200 one by one, and the aperture of each first through hole 112 is preferably greater than or equal to the aperture of the corresponding mounting hole 210. In this way, when the product 200 is inserted into the slot 111, each mounting hole 210 on the product 200 corresponds to each first through hole 112 one by one, as shown in FIG. Fig.10 , Fig.12 When the release paper at each mounting hole 210 is pressed down and peeled off, it is recovered downward through each first through hole 112, as shown. Fig.12 As shown, avoid interference between release papers and affect recycling.

[0046] It is understandable that the method is not limited to opening multiple first through holes 112. For example, in other embodiments, a first through hole 112 with a larger aperture is opened on the bottom plate 153 of the product fixing part 110, so that the outer diameter of the first through hole 112 is greater than or equal to the outer diameter of the entire area where the mounting hole 210 is set on the product 200, and the release paper after peeling can also be recovered downward.

[0047] In addition, the structure of the product fixing member 110 is not limited to that in this embodiment. For example, in other embodiments, the product fixing member 110 may include two clamping blocks arranged opposite to each other, and the two clamping blocks are moved relative to each other to clamp and fix the product 200 and release the product 200. In this manner, the first through hole 112 does not need to be provided on the product fixing member 110.

[0048] Combine the following Figure 2-Figure 5 , Fig.12As shown, in one embodiment of the present invention, since it is mainly used to peel off the release paper at the position of the mounting hole 210 on the product 200, the lower end of the pressing punch 122 is provided with a conical pushing end 1221. In a specific embodiment, the pushing end 1221 is conical and needle-shaped. In this way, the pushing end 1221 can easily pass through the mounting hole 210 on the product 200 to press the release paper, and push the release paper to pass through the first through hole 112 and the second through hole 1511 in sequence and enter the suction channel 131, as shown in FIG. Fig.12 As shown, this structural setting can quickly peel off the release paper at the position of the mounting hole 210 with a smaller outer diameter. Of course, the shape of the push end 1221 is not limited to that in this embodiment. For example, according to the different shapes and diameters of the mounting hole 210 on the product 200, the lower end of the pressing punch 122 can also be gradually narrowed to form a tapered structure at its lower end. Of course, the push end 1221 can also be set to other shapes.

[0049] Continue to combine Figure 2-Figure 5 , Fig.12 As shown, in one embodiment, it is mainly used to peel off the release paper of the product 200 having multiple mounting holes 210. Therefore, the peeling drive assembly 120 also includes a fixing plate 123, and multiple pressing punches 122 are fixed to the lower end of the driving member 121 through the fixing plate 123. Specifically, the top surface of the fixing plate 123 is fixed to the lower end of the driving member 121, and the bottom surface of the fixing plate 123 is fixed to the multiple pressing punches 122. The position layout between the multiple pressing punches 122 corresponds to the layout of the multiple mounting holes 210 on the product 200, as shown in FIG. Fig.12 In this way, the driving member 121 can drive the multiple pressing punches 122 to move downward synchronously through the fixing plate 123, and the multiple pressing punches 122 respectively pass through the respective mounting holes 210 on the product 200, so as to peel off the release papers at the positions of the multiple mounting holes 210 at the same time, thereby further improving the peeling efficiency of the release papers.

[0050] Combine the following Figure 8-Figure 9 , Fig.12 As shown, in one embodiment of the present utility model, the suction channel 131 includes a first channel section 1311 and a second channel section 1312 located below the first channel section 1311. The first channel section 1311 is a long strip structure in the horizontal direction, such as Fig. 9As shown, the outer diameter of the first flow channel section 1311 is preferably greater than or equal to the outer diameter of the second through hole 1511 on the top plate 151. In this embodiment, the shape and outer diameter of the first flow channel section 1311 correspond to the shape and outer diameter of the second through hole 1511. The second flow channel section 1312 is circular and corresponds to the inner diameter of the adsorption tube 141. When the suction guide 130 is fixed between the top plate 151 and the bottom plate 153 of the mounting seat 150, it forms a sealed connection with the top plate 151 and the bottom plate 153 respectively, and the first flow channel section 1311 corresponds to the second through hole 1511, and the second flow channel section 1312 is sealedly connected to the adsorption tube 141, so that the second through hole 1511 on the top plate 151, the suction channel 131, and the adsorption tube 141 are connected in sequence, as shown in FIG. Fig. 9 In this embodiment, the suction channel 131 is opened in a shape with a larger opening at the upper end and a narrower opening at the lower end. During negative pressure adsorption, a relatively small adsorption force can suck the release paper into the suction channel 131, so that the release paper can be quickly sucked into the suction channel 131 to prevent the release paper from clogging the suction channel 131, which not only improves the recovery efficiency of the release paper, but also improves the overall stripping efficiency of the release paper.

[0051] More preferably, the second flow channel section 1312 is vertically arranged, and the first flow channel section 1311 is inclined compared to the second flow channel section 1312. Therefore, the inclined slope in the first flow channel section 1311 has a better guiding effect. The release paper entering the suction channel 131 can quickly enter the second flow channel section 1312 under the guidance of the first flow channel section 1311, so that the release paper can quickly fall into the adsorption tube 141, thereby improving the recovery efficiency of the release paper.

[0052] Combine the following Figure 6-7 , Figure 10-11 As shown, in one embodiment of the utility model, the release paper peeling device 100 further includes a proximity switch 160 and a time delay relay 170. The proximity switch 160 is mounted on the bottom plate 151 of the product fixing member 110 or the mounting seat 150, and the proximity switch 160 is used to detect the product 200 on the product fixing member 110. The time delay relay 170 is mounted on the mounting seat 150 and is used to time the pressing time of the pressing punch 122. In addition, the proximity switch 160 and the time delay relay 170 are electrically connected to the control circuit respectively. In addition, the vacuum generator is also electrically connected to the control circuit. In this way, when the proximity switch 160 detects the product 200, the driving member 121 drives the pressing punch 122 to extend and press down, and at the same time, the vacuum generator starts to operate. When the timing of the time delay relay 170 reaches a preset time length, the driving member 121 drives the pressing punch 122 to retract.

[0053] Continue to view Figure 6-7 As shown, in one embodiment of the present invention, a third through hole 113 is opened on the bottom plate 153 of the product fixing member 110, and the proximity switch 160 is installed on the bottom plate 151 and accommodated in the third through hole 113, as shown in FIG. Figure 6 As shown. In this way, when the product 200 is inserted into the card slot 111, the proximity switch 160 can accurately detect the product 200, ensuring the accuracy of the detection. At the same time, the proximity switch 160 will not be squeezed during the process of the product 200 being pressed into the card slot 111, preventing the proximity switch 160 from being damaged. Of course, the proximity switch 160 can also be installed at other positions where the product 200 on the product fixture 110 can be detected.

[0054] Combine the following Figure 2-7 , Figure 10-11 As shown, in one embodiment of the present invention, the release paper peeling device 100 further includes a start switch 180 and an emergency stop switch 190, which are mounted on the bottom plate 151 and are electrically connected to the control circuit respectively. The control circuit can be powered on by pressing the start switch 180, and the control circuit can be powered off by pressing the emergency stop switch 190. The settings of the two are conventional in the art and will not be described in detail.

[0055] Combine again Figure 1-Figure 2 As shown, in a preferred embodiment of the utility model, a plurality of workstations can be arranged on a mounting seat 150, that is, a plurality of product fixings 110 are arranged at intervals on a mounting seat 150, and each product fixing 110 is correspondingly configured with a peeling drive component 120 and a vacuum adsorption component 140, thereby forming a plurality of workstations, thereby further improving the peeling efficiency of the release paper and improving the overall production capacity. Figure 1 The release paper peeling device 100 is shown as having two working stations. Figure 2 The release paper peeling device 100 is shown as having one working station, but the above-mentioned figure cannot be used as a limitation to the present application.

[0056] Combine again below Figure 1-Figure 12 As shown, the working principle and process of the release paper peeling device 100 of the present invention are described.

[0057] like Fig.10As shown, first, the product 200 with the release paper is inserted into the card slot 111 of the product fixing member 110, and the side of the product 200 with the release paper is made to fit the bottom plate of the product fixing member 110. At this time, the product 200 is locked and positioned by the product fixing member 110, and the mounting holes 210 on the product 200 correspond one-to-one with the first through holes 112 on the product fixing member 110, as shown in FIG. Fig.12 shown.

[0058] When the product 200 is inserted into the card slot 111, the product 200 blocks the third through hole 113 on the product fixing member 110, so the proximity switch 160 located in the third through hole 113 senses the product 200. At this time, the driving member 121 starts to move and drives the pressing punch 122 to extend downward. At the same time, the vacuum generator starts to work and generates negative pressure. When the driving member 121 drives the pressing punch 122 to press downward, the delay relay 170 starts to count the pressing time of the driving member 121.

[0059] See also Figure 11-12 As shown, after the driving member 121 drives the pressing punch 122 to press down to the right position, the pushing end 1221 of the pressing punch 122 passes through the mounting holes 210 on the product 200 and presses down the release paper below the product 200. Since the product 200 is fixed, and the mounting holes 210 of the product 200 are respectively below the first through hole 112 on the product fixing member 110 and the second through hole 1511 on the top plate 151, the pushing end 1221 can press down the release paper to separate it from the product 200, and press down the release paper to pass through the first through hole 112 and the second through hole 1511 and enter the suction channel 131, as shown in FIG. Fig.12 At the same time, under the negative pressure generated by the vacuum generator, the release paper is sucked into the suction channel 131 and the adsorption tube 141 to achieve the recovery of the release paper.

[0060] like Figure 2 , Fig.10 As shown, when the timer of the delay relay 170 reaches the preset time length, the delay relay 170 outputs a trigger signal to the control circuit, and the driving member 121 drives the pressing punch 122 to retract. Then, the product 200 can be picked up from the product fixing member 110 to complete the peeling of the release paper of the product 200.

[0061] Then, the next product 200 is inserted into the card slot 111 on the product fixing member 110, and the above-mentioned action is repeated to start peeling off the release paper on the product 200 again. This cycle is repeated to achieve the peeling off of the release paper of the product 200.

[0062] See also Figure 1As shown, for a release paper peeling device 100 with multiple workstations, release paper can be peeled off from multiple products 200 at the same time, thereby greatly improving the peeling efficiency of the release paper and further improving the production capacity.

[0063] To summarize, the release paper peeling device 100 of the utility model is provided with a peeling drive assembly 120 located above the product fixing part 110, and the peeling drive assembly 120 includes a driving member 121 and a downward pressing punch 122 connected to the lower end of the driving member 121, and the driving member 121 is used to drive the downward pressing punch 122 to extend and retract, and a vacuum adsorption assembly 140 is provided below the product fixing part 110, and the vacuum adsorption assembly 140 includes an adsorption tube 141 and a vacuum generator connected to the adsorption tube 141, and the adsorption tube 141 is docked at the bottom of the product fixing part 110. Therefore, after the product 200 with the release paper is positioned by the product fixing part 110, the side of the product 200 with the release paper is located at the bottom, and then the driving part 121 drives the pressing punch 122 to extend and press the release paper downward, so that the release paper is separated from the product 200, and then the negative pressure generated by the vacuum generator below sucks the release paper out, thereby realizing the automatic stripping and recycling of the release paper, which not only reduces the labor intensity, but also improves the working efficiency, increases the production capacity and reduces the production cost. It is particularly suitable for the automatic stripping of the release paper at the installation hole 210 position of the product 200.

[0064] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
