Description

Technical Field

[0001] This application relates to the field of film peeling technology, and more specifically to a film peeling device. Background Technology

[0002] Currently, decorative film printing and coating are widely used for printing on card-type film materials. However, due to the susceptibility of decorative film surfaces to scratches and dust contamination, the defect rate in the printing process increases dramatically, seriously affecting the product qualification rate. Therefore, it is necessary to coat the surface of the base material before printing to protect the decorative film surface from contamination and damage. Consequently, a film peeling operation is required for each individual film sheet during the printing process.

[0003] Traditional film-tearing operations are done manually. The operator holds the product in one hand and uses the other to grip the film-tearing handle, tearing the film along the surface – a labor-intensive process. Therefore, with the widespread adoption of automated production lines, automatic film-tearing equipment typically uses adhesive tape as a consumable. This tape is used to hold the film-tearing handle in place, and is replaced when it runs out. However, in actual use, there is a risk of product (glass substrate) breakage. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the purpose of this application is to provide a film-peeling device that prevents the product to be peeled from moving and breaking during the film-peeling process.

[0011] In one embodiment, the film-tearing assembly includes a pressing cylinder, a connecting rod, and a roller. The pressing cylinder is mounted on a base, and the connecting rod is located at the output end of the pressing cylinder. The end of the connecting rod away from the pressing cylinder is connected to the roller.

This design can, on the one hand, avoid the product to be peeled from shifting during the peeling process, thus affecting the peeling efficiency. On the other hand, since the area of ​​the product to be peeled in this application is large and the thickness is thin, the support of the transport component only plays a partial supporting role, and the force is uneven, which can easily cause the product to break during peeling. In contrast, the adsorption positioning platform supports the product to be peeled, and compared to the transport component, the support area of ​​the adsorption positioning platform is larger, close to the entire surface of the product to be peeled. The force on the product to be peeled is relatively uniform, so the product to be peeled is not easy to break during the peeling process, thus improving production efficiency.

The positioning and conveying mechanism 300 includes a base 10 and a positioning component 20, a lifting component 30, and a conveying component 40 disposed on the base 10. The positioning component 20 is used to limit and fix the product to be peeled, and includes an adsorption positioning platform 21. The lifting component 30 is located on the side of the adsorption positioning platform 21 close to the base 10, and is used to drive the adsorption positioning platform 21 closer to or away from the base 10. The adsorption positioning platform 21 is provided with a through hole 212 through which part of the conveying component 40 can pass. The film-peeling mechanism 500 includes a moving component 50 and a film-peeling component 60. The film-peeling component 60 is disposed on the moving component 50. When the adsorption positioning platform 21 is in the rising state, the adsorption positioning platform 21 is used to adsorb and fix the product to be peeled, and the moving component 50 is used to drive the film-peeling component 60 to remove the protective film from the surface of the product to be peeled. When the adsorption positioning platform 21 is in the falling state, the conveying component 40 is used to transport the product to be peeled. In this embodiment, the positioning and conveying mechanism 300 completes the transfer and fixation of the product to be peeled in two steps. For example, when the adsorption positioning platform 21 is in the descending state, the conveying component 40 transfers the product to be peeled. When the adsorption positioning platform 21 is in the ascending state, the product to be peeled is fixed by the adsorption positioning platform 21, and the product is peeled in this state. This design can, on the one hand, avoid the product to be peeled from shifting during the peeling process of the peeling mechanism 500, thereby affecting the peeling efficiency. On the other hand, since the area of ​​the product to be peeled in this application is large and the thickness is thin, the support of the transport component only plays a partial supporting role, and the force is uneven, which can easily cause the product to break during peeling. However, the adsorption positioning platform 21 supports the product to be peeled. Compared with the transport component, the support area of ​​the adsorption positioning platform 21 is larger, close to the entire surface of the product to be peeled. The force on the product to be peeled is relatively uniform. Therefore, the product to be peeled is not easy to break during the peeling process of the peeling mechanism 500, thus improving production efficiency.

[0022] Next, combine Figures 1-8 The following describes the film-tearing device provided in the embodiments of this application. The film-tearing device includes a base 100, a feeding mechanism 200, a positioning conveying mechanism 300, a film-tearing mechanism 500, a discharging mechanism 400, and a waste recycling mechanism 600. The feeding mechanism 200, the positioning conveying mechanism 300, and the discharging mechanism 400 are sequentially arranged on the base 100 along a first direction (X direction). The film-tearing mechanism 500 is arranged on the base 100 and located above the positioning conveying mechanism 300, and is used to tear the film off the product to be peeled on the positioning conveying mechanism 300.

[0023] The positioning conveyor 300 is located on one side of the feeding mechanism 200 in the first direction (X direction), and the discharging mechanism 400 is located on the side of the positioning conveyor 300 opposite to the feeding mechanism 200 in the first direction (X direction). It can also be understood that the positioning conveyor 300 is located downstream of the feeding mechanism 200, and the discharging mechanism 400 is located downstream of the positioning conveyor 300. The feeding mechanism 200 transports the product to be peeled to the positioning conveyor 300, and the positioning conveyor 300 then transports the peeled product to the discharging mechanism 400. The positioning conveyor 300 is used to receive the product to be peeled from the feeding mechanism 200, and to limit, fix and support the product to be peeled to prevent the product to be peeled from moving and breaking during the peeling process.

[0024] refer to Figures 2-6 In one specific embodiment, the positioning and conveying mechanism 300 includes a base 10 and a positioning component 20, a lifting component 30, and a conveying component 40 disposed on the base 10. The positioning component 20 is used to limit and fix the product. The positioning component 20 includes an adsorption positioning platform 21, which has a bearing surface for carrying the product to be peeled off. The lifting component 30 is located on the side of the adsorption positioning platform 21 near the base 10. The lifting component 30 is used to drive the adsorption positioning platform 21 closer to or away from the base 10. The adsorption positioning platform 21 has a through hole 212 through which part of the conveying component 40 can pass. When the adsorption positioning platform 21 is in a descending state (e.g. Figure 3 As shown), the conveying component 40 is used to convey the product to be peeled off. When the adsorption positioning platform 21 is in the rising state (as shown), Figure 4As shown, the adsorption positioning platform 21 is used to adsorb and fix the product to be peeled, and during this process, the moving component 50 is used to drive the peeling component 60 to remove the protective film from the surface of the product to be peeled. In this embodiment, the positioning and conveying component 40 completes the transfer and fixation of the product to be peeled in two steps. For example, when the adsorption positioning platform 21 is in the descending state, the conveying component 40 transfers the product to be peeled. When the adsorption positioning platform 21 is in the ascending state, the product to be peeled is fixed by the adsorption positioning platform 21, and the product is peeled in this state. This design can, on the one hand, avoid the product to be peeled from shifting during the peeling process of the peeling mechanism 500, thereby affecting the peeling efficiency. On the other hand, since the area of ​​the product to be peeled in this application is large and the thickness is thin, the transport component only provides partial support for the product to be peeled, and the force is uneven, which can easily cause the product to break during peeling. However, the adsorption positioning platform 21 supports the product with the peeled film. Compared with the transport component, the adsorption positioning platform 21 has a larger support area for the product to be peeled, which is close to supporting the entire surface of the product to be peeled. The force on the product to be peeled is relatively uniform. Therefore, the product to be peeled is not easy to break during the peeling process of the peeling mechanism 500, thus improving the efficiency of the production system.

When performing film-tearing operations on the product, the first moving module 52 and the second moving module 53 first slide the third moving module 54 above the film-tearing start position of the adsorption positioning platform 21. Then, the third moving module 54 drives the film-tearing assembly 60 to descend. During the descent, the tape on the film-tearing roller 64 in the film-tearing assembly 60 first comes into contact with the protective film at one corner of the product to be peeled. The third moving module 54 then drives the film-tearing assembly 60 to continue descending a certain distance, increasing the adhesion between the tape on the film-tearing roller 64 and the protective film, reducing the possibility of the protective film detaching from the tape, and further improving the success rate of film peeling. During this process, since the product is adsorbed on the adsorption positioning platform 21 and the adsorption platform provides full-surface support for the product, the product will not break after the tape on the film-tearing roller 64 comes into contact with the product.

[0037] In one specific embodiment, the film-tearing assembly 60 further includes a pressing cylinder 661 (not shown in the figure), a connecting rod 662, and a roller 663. The pressing cylinder 661 is mounted on the base 61, and the connecting rod 662 is mounted on the output end of the pressing cylinder 661. The end of the connecting rod 662 away from the pressing cylinder 661 is connected to the roller 663. The pressing cylinder 661 drives the connecting rod 662 to extend and retract, thereby causing the roller 663 to press against or move away from the film-tearing roller 64. When the tape on the film-tearing roller 64 in the film-tearing assembly 60 adheres to one side of the protective film... After the corner is removed, the third drive unit 65 drives the take-up roller 63 to rotate, thereby driving the tape transmission so that the protective film stuck to the tape on the tearing roller 64 can be wrapped around the tearing roller 64. At the same time, the roller 663 in the pressing assembly presses the protective film to the tearing roller 64. This design prevents the protective film from falling off the tape on the tearing roller 64 during the movement of the tearing assembly 60. Then, the first moving module 52 and the second moving module 53 move synchronously, driving the tearing assembly 60 to move along a diagonal line of the adsorption positioning platform 21.

[0038] In one specific embodiment, the film-tearing assembly 60 further includes a fixed-length conveying roller 671 rotatably mounted on a base and a rotary encoder 672 for sensing the conveying length of the fixed-length conveying roller 671. The fixed-length conveying roller 671 is located between the take-up roller 63 and the film-tearing roller 64, and is used to contact and support the tape. The rotary encoder 672 on the fixed-length conveying roller 671 can detect the rotational speed of the speed measuring roller, thereby calculating the length of the tape conveyed by the fixed-length conveying roller 671. Then, based on the length data from the rotary encoder 672, the third drive unit 65 is adjusted, which can dynamically adjust the take-up length of the take-up roller 63. Specifically, the process is as follows: Firstly, the tape on the tearing roller 64 in the tearing assembly 60 first comes into contact with the protective film on the product, and after the tape on the tearing roller 64 and the protective film are firmly adhered, the third drive unit 65 drives the take-up roller 63 to rotate to achieve take-up. During this process, the rotary encoder 672 measures the length of the tape being wound according to the rotation speed of the fixed-length conveyor roller 671. After the take-up roller 63 has wound up a certain length, the third drive unit 65 stops running. During this process, the tearing roller 64 rotates synchronously, thereby wrapping part of the protective film of the product onto the tearing roller 64. This design increases the technical area between the tape on the tearing roller and the protective film on the product, reduces the possibility of the protective film separating from the tape, and further improves the success rate of tearing.

[0039] On the other hand, after the film-tearing mechanism 500 completely removes the protective film from the product, the film-clamping assembly 70 in the waste recycling mechanism 600 will clamp the removed protective film into the waste film box 80. However, during the clamping process of the film-clamping assembly 70, some protective film will stick to the tape on the film-tearing tube. If the tape with the protective film is used to tear the new product to be peeled again, it will affect the film-tearing efficiency. Therefore, the third drive unit 65 drives the take-up roller 63 to rotate to achieve take-up. During this process, the rotary encoder 672 measures the length of the tape being wound according to the rotation speed of the fixed-length conveyor roller 671. After the take-up roller 63 has wound a certain length, the third drive unit 65 stops running. During this process, the film-tearing roller 64 rotates synchronously, thereby wrapping the tape with the protective film around the take-up roller 63. New tape is also set on the film-tearing roller 64 at the same time. This design can further improve the success rate of film tearing.

[0040] It should be noted that the fixed-length conveying roller 671 in this embodiment is a driven roller. During the film-tearing operation, when the tape is used up and the fixed-length conveying roller 671 is no longer in contact with the tape, the fixed-length conveying roller 671 will stop rotating. At this time, the stop signal detected by the rotary encoder 672 can also be used as a tape feedback signal to remind the staff to replace the tape roll.

[0041] In one specific embodiment, the film-tearing assembly 60 further includes an optical fiber sensor 68 disposed on the base 61.

[0042] refer to Figure 1and Figure 8 In one specific embodiment, the film-tearing device further includes a waste recycling mechanism 600. The waste recycling mechanism 600 is disposed on the side of the base 100 near the film-tearing termination position. The waste recycling mechanism 600 includes a film clamping assembly 70 and a waste film box 80. The film clamping assembly 70 is disposed on the base 100. The film clamping assembly 70 includes a fourth driving part 71 and a film clamping part 72 disposed on the fourth driving part 71. The fourth driving part 71 is used to drive the film clamping part 72 to rotate in a preset direction. The film clamping part 72 includes a gripper cylinder 721 and an upper clamping arm 722 disposed on the gripper cylinder 721.
