[0054] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0055] Embodiment 1

[0056] See also Figure 1 , Figure 2 and Figure 3 This embodiment provides an automatic film-tearing device, which is suitable for the film-tearing operation of the release film 30 on the 3C camera lens module.

[0057] The release film 30 on the 3C camera lens module (hereinafter referred to as the product 10) is a circular film and covers the adhesive backing 20. The adhesive backing 20 is bonded to the product 10 and is in a ring shape, and the middle part is a hollow area 21 without adhesive. The release film 30 also has a circular hole 31 in the middle part, and the area of ​​the circular hole 31 is smaller than the area of ​​the hollow area 21, so that the hollow area 21 is at least partially covered by the release film 30.

[0058] In this embodiment, the automatic film tearing device includes a positioning fixture 100, a pressing mechanism 200 and a film tearing mechanism 300. The positioning fixture 100 is provided with a positioning area 110, and the positioning area 110 is used to install and position the product 10 to be film-torn.

[0059] The pressing mechanism 200 is arranged on one side of the positioning fixture 100 and includes a pressing member 220, which has a pressing state and a decompressing state. In the pressing state, the pressing member 220 presses into the positioning area 110 to press the film-free area of ​​the product 10 to prevent interference with film tearing; in the decompressing state, the pressing member 220 deviates from the positioning area 110, and the pressing of the product 10 is released at this time, so as to facilitate the loading and unloading of the product 10.

[0060] It should be noted that if the product 10 is a 3C camera lens module, the circular release film 30 has no tear marks or break lines, and the release film 30 has a strong adhesion to the product 10. Therefore, in order to prevent the product 10 from moving when tearing the film and ensure successful film tearing, in this embodiment, the product 10 is pressed down by a clamping member 220 to prevent the release film 30 from having too strong an adhesion force, causing the product 10 to be lifted up during the film tearing process, thereby protecting the product 10 and ensuring successful film tearing.

[0061] The film peeling mechanism 300 includes a film peeling robot 310 and a film clamping module 320. The film clamping module 320 is arranged on the film peeling robot 310 and is provided with a film clamping tweezers 330. The film clamping module 320 includes a film taking state and a film unloading state. In the film taking state, the film clamping tweezers 330 extends into the positioning area 110. The film peeling robot 310 has a six-axis mechanical arm with high degree of freedom and more flexible control.

[0062] It can be understood that the automatic film tearing device provided in this embodiment positions and clamps the product 10 to be torn off to the positioning area 110 through the positioning fixture 100, and then switches to the clamping state through the clamping member 220 of the clamping mechanism, and the clamping member 220 is pressed into the positioning area 110 to press the film-free area of ​​the product 10, and then the film tearing robot 310 drives the film clamping module 320 to enter the film removal state, so that the film clamping tweezers 330 are extended into the positioning area 110 and clamp the release film 30 covering the product 10, and then the film tearing robot 310 completely tears off the release film 30 according to the characteristics of the release film 30 according to the preset film tearing action, so that the release film 30 is separated from the product 10, and finally the release film 30 is transferred to the designated position for unloading, and the film clamping tweezers 330 releases the clamping of the torn release film 30.

[0063] Compared with the prior art, the automatic film tearing device provided in this embodiment utilizes the flexibility of the film tearing robot 310 and cooperates with the film clamping tweezers 330 to achieve film clamping, film tearing and film unloading. The tip of the film clamping tweezers 330 can enter narrow spaces and gaps to clamp films, especially suitable for tearing films of round and small size without tearing holes and break lines. Such release films 30 have strong adhesion to the product 10, and thus the product 10 is pressed by the clamping member 220 to prevent the adhesion of the release film 30 from being too strong, and the product 10 is lifted up during the film tearing process, thereby damaging the product 10. Furthermore, with the cooperation of the film tearing robot 310, the damage to the product 10 can be further reduced, and the flexibility of film tearing can be improved.

[0064] See also Figure 1 , Figure 2 and Figure 3 In order to more clearly describe the technical solution of the present application, the automatic film tearing device provided in this embodiment is described below. The details are as follows:

[0065] In this embodiment, the pressing mechanism 200 further includes a pressing drive module 210. The pressing drive module 210 is arranged on one side of the positioning fixture 100. In some embodiments, the positioning fixture 100 and the pressing drive module 210 can share a frame. Specifically, the pressing drive module 210 is installed on the frame through a film pressing fixing seat 230. The pressing member 220 is arranged on the pressing drive module 210 and includes a product contact portion 221, and a film tearing area avoidance hole 222 is provided on the product contact portion 221.

[0066] In some embodiments, the film tearing area avoidance hole 222 may also be designed in the form of a notch.

[0067] In this way, the compression drive module 210 can drive the compression member 220 to switch between the compression state and the decompression state. The film tearing area avoidance hole 222 can facilitate the entry and exit of the film clamping forceps head 330, and at the same time facilitate the removal of the torn release film 30. The area of ​​the film tearing area avoidance hole 222 is larger than the area of ​​the release film 30, so that the entire release film 30 can be exposed in the film tearing area avoidance hole 222.

[0068] It can be understood that the pressing member 220 presses the product 10 in a manner of pressing the film-free area of ​​the product 10 from top to bottom.

[0069] Therefore, in some embodiments, the compression drive module 210 can be selected as a flip module that outputs a flipping motion. The flip module drives the compression member 220 to flip in a vertical plane, for example, from 0° to 90°. When the compression member 220 is at the 0° position, it corresponds to a compression state; when the compression member 220 is at the 90° position, it corresponds to a decompression state.

[0070] Specifically, the clamping drive module 210 includes a base and a first cylinder disposed on the base, the clamping member 220 is hinged on the base and hinged to the first cylinder, and the clamping portion is located at one end of the clamping member 220 away from the first cylinder. In this way, the first cylinder outputs a telescopic movement in the vertical direction to drive the clamping member 220 to flip in a vertical plane. Optionally, the first cylinder can also be replaced by an oil cylinder, an electric cylinder or an electric push rod. Of course, a rotary cylinder can also be used to directly drive the clamping member 220 to flip in a vertical plane.

[0071] In this embodiment, the compression drive module 210 is a linear module that outputs linear reciprocating motion. The linear module can drive the compression member 220 to rise and fall in the vertical direction to achieve the switching of the compression member 220 between the compression state and the decompression state.

[0072] Specifically, the compression drive module 210 includes a base and a second cylinder disposed on the base, and the compression member 220 is disposed on the piston rod of the second cylinder. In this way, the compression member 220 is driven by the second cylinder to rise and fall in the vertical direction, so as to realize the switching of the compression member 220 between the compression state and the decompression state. Optionally, the second cylinder can also be selected to be replaced by an oil cylinder, an electric cylinder or an electric push rod.

[0073] It should be understood that the above-described compression drive module 210 is only an example and is not intended to limit the scope of protection of the present application.

[0074] The film clamping module 320 includes a transfer shaft 321, a film clamping driving mechanism 322 and a chuck seat 323. The transfer shaft 321 is in transmission connection with the film tearing robot 310, and the film tearing robot 310 can drive the transfer shaft 321 to rotate. The film clamping driving mechanism 322 is disposed on the transfer shaft 321, and the film clamping driving mechanism 322 can rotate with the transfer shaft 321. The chuck seat 323 is disposed at the driving end of the film clamping driving mechanism 322, wherein the film clamping forceps head 330 is disposed on the chuck seat 323.

[0075] It is understandable that the film-tearing robot 310 has a six-axis robotic arm with a high degree of freedom and more flexible control. In this way, the entire film clamping module 320 can be driven to tear the film according to a preset motion trajectory, so that it can be suitable for tearing the film of a complex release film 30. The film clamping drive mechanism 322 can drive the film clamping tweezers 330 to close and open, and the film clamping tweezers 330 can clamp the release film 30 after closing. And the tip of the head of the film clamping tweezers 330 can enter a narrow space and gap to clamp the film, that is, the film clamping tweezers 330 can extend into the circular hole 31 of the release film 30. Since the area of ​​the circular hole 31 is smaller than the area of ​​the hollow area 21, the film clamping tweezers 330 can smoothly clamp the release film 30 located in the hollow area 21 of the back glue 20.

[0076] Optionally, the clamping forceps head 330 is made of carbon fiber or plastic.

[0077] Specifically, when tearing the film, the film tearing robot 310 controls the film clamping tweezers 330 to be obliquely inserted into the circular hole 31 of the release film 30, and then lifted up to make the film clamping tweezers 330 contact with the release film 30 and make the inner edge of the release film 30 separate from the adhesive backing 20, and then the film clamping tweezers 330 is lifted up with a small displacement while continuing to insert the film clamping tweezers 330 without touching the adhesive backing 20. After a certain displacement, the film clamping pneumatic fingers in the film clamping driving mechanism 322 are closed so that the film clamping tweezers 330 clamp the release film 30. In this way, the film tearing mechanism 300 and the product 10 are at a specific angle to perform the film tearing action (human bionic action) until the film tearing is completed.

[0078] It should be noted that the aperture of the circular hole 31 of the release film 30 on the 3C camera lens module is usually small, for example, the aperture is 3.5mm, so the insertion space is small, and the contact range between the film clamping tweezers 330 and the film is as small as 1.34mm after insertion. In this way, only the head of the film clamping tweezers 330 can be used to enter, and other clamping structures cannot smoothly enter to clamp the release film 30. At the same time, the release film 30 is a whole sheet without a fracture line, so it is necessary to select a high-strength carbon fiber-containing plastic or carbon fiber material for the film clamping tweezers 330. Other types of films have fracture lines, which can make the film and the product have a breakthrough point, line, or surface when tearing the film. The tearing force is very small, the action is simple, and the film clamping parts can be simple metal parts, and the product will not be damaged.

[0079] In some embodiments, a plurality of film clamping tweezers 330 are provided, and the plurality of film clamping tweezers 330 are arranged in parallel on the clamping head seat 323, so as to be driven to move synchronously by the film clamping driving mechanism 322. In this way, the synchronous film tearing of the plurality of release films 30 can be achieved, and the film tearing efficiency can be improved.

[0080] See also Figure 1 In some embodiments, the automatic film tearing device further includes a film discharge mechanism 500 , which is arranged on one side of the pressing mechanism 200 and is externally connected to a waste film collection container, which is used to centrally collect the torn release film 30 .

[0081] Specifically, the film discharge mechanism 500 includes a vacuum generator 510, a film discharge nozzle 520 and a film discharge tube 530. The air inlet end of the vacuum generator 510 is connected to the film discharge nozzle 520. The air outlet end of the vacuum generator 510 is connected to the film discharge tube 530, and the film discharge tube 530 is externally connected to the waste film collection container. In this way, after the film tearing robot 310 tears off the film, the release film 30 is clamped by the film clamping tweezers 330 at this time. The film tearing robot 310 is controlled to drive the film clamping tweezers 330 to move above the film discharge nozzle 520 and close to the film discharge nozzle 520, and then the film clamping driving mechanism 322 is controlled to drive the film clamping tweezers 330 to open, and at the same time the vacuum generator 510 is started to generate negative pressure in the film discharge nozzle 520, so that the release film 30 on the film clamping tweezers 330 is sucked into the film discharge tube 530, and enters the waste film collection container along the film discharge tube 530 for collection. In this way, the torn release films 30 are collected centrally by utilizing vacuum negative pressure, thereby preventing the release films 30 from interfering with the normal operation of the equipment and improving simplicity.

[0082] Optionally, the vacuum generator 510 includes a vacuum pump that generates negative pressure.

[0083] Embodiment 2

[0084] See also Figure 1 , Figure 3 and Figure 4 This embodiment provides an automatic film-tearing device. The automatic film-tearing device provided in this embodiment is an improvement made on the technical basis of the above-mentioned embodiment 1. Compared with the prior art, the difference is that:

[0085] In this embodiment, the automatic film tearing device further comprises a turntable mechanism 400, and a loading station 410 and a film tearing station 420 are arranged around the turntable mechanism 400. The turntable mechanism 400 is driven by a motor to rotate.

[0086] Among them, the positioning fixture 100 is arranged on the turntable mechanism 400, and the pressing mechanism 200 is arranged at the film tearing station 420. The film tearing robot 310 is arranged on one side of the turntable mechanism 400. In this way, the loading station 410 can be used for loading and unloading the product 10 to save one unloading station, and the film tearing station 420 is used for film tearing operations. The turntable mechanism 400 can drive the positioning fixture 100 to rotate so that the positioning fixture 100 can pass through the loading station 410 and the film tearing station 420 in sequence. In some embodiments, a unloading station can also be set separately.

[0087] Furthermore, the number of positioning fixtures 100 arranged on the turntable mechanism 400 is consistent with the number of workstations around the turntable mechanism 400, thereby ensuring that loading and unloading and film tearing can be performed synchronously, thereby improving work efficiency.

[0088] In some embodiments, the automatic film tearing device further includes a film discharge mechanism 500, which is arranged at the film tearing station 420 and located on one side of the pressing mechanism 200. The film discharge mechanism 500 is externally connected to a waste film collection container, which is used to centrally collect the torn release film 30. The film discharge mechanism 500 has been described in detail in the above-mentioned embodiment 1, and will not be repeated here.

[0089] In order to ensure whether the release film 30 on the product 10 is torn off. To this end, the present embodiment further provides a detection station 430 around the turntable mechanism 400. In this way, after the product 10 is loaded onto the positioning fixture 100, the turntable mechanism 400 first drives the positioning fixture 100 to enter the film tearing station 420; after the film tearing is completed, the positioning fixture 100 is transferred to the detection station 430; after the detection is completed, the turntable mechanism 400 transfers the positioning fixture 100 to the loading station 410.

[0090] Of course, in some embodiments, in order to ensure that the beats of each station are consistent, a buffer station 440 can be arranged between the detection station 430 and the film tearing station 420, and no device is set in the buffer station 440. When the positioning fixture 100 is transferred to the buffer station 440, it waits. When the detection station 430 completes the detection, the turntable mechanism 400 drives the positioning fixture 100 to enter the detection station 430 for detection.

[0091] See also Figure 1 , Figure 3 and Figure 4 The automatic film tearing device further includes a film tearing detection mechanism 600 disposed at the detection station 430 , and the film tearing detection mechanism 600 is used to detect whether the release film 30 on the product 10 is torn off.

[0092] Specifically, the film tearing detection mechanism 600 includes a test frame 610, an upper test probe 620, a test circuit 630, a test drive module 640 and a lower test probe 650. The test frame 610 is installed on the frame, and the upper test probe 620 is arranged on the test frame 610 and connected to the test circuit 630. The test drive module 640 is arranged on the test frame 610; the lower test probe 650 is arranged on the test drive module 640 and connected to the test circuit 630, the lower test probe 650 is located below the upper test probe 620 and is arranged in alignment with the upper test probe 620, and the test end 6521 of the lower test probe 650 is arranged toward the positioning fixture 100 located at the detection station 430.

[0093] Please also read Figure 5, wherein the test drive module 640 can drive the lower test probe 650 to rise and fall in the vertical direction. The lower test probe 650 includes a test seat 651 and a probe body 652. The test seat 651 is arranged on the test drive module 640. A syringe 653 is arranged on the test seat 651. The probe body 652 is connected by a spring and can float in the syringe 653. The lower end of the probe body 652 is a test end 6521, and the upper end is a sensing end 6520. The diameter of the test end 6521 is larger than the aperture of the circular hole 31 of the release film 30.

[0094] It is understandable that when the release film 30 is torn off, the lower test probe 650 will descend without the obstruction of the release film 30, so the test end 6521 of the probe body 652 will directly enter the hollow area 21 of the back glue 20 (the back glue 20 has a certain thickness, so the hollow area 21 has a certain depth). At this time, the sensing end 6520 of the probe body 652 will not contact the upper test probe 620, so that the test circuit 630 is in a disconnected state, and the test circuit 630 will not send a signal at this time, then it is judged that the release film 30 is torn off. When the release film 30 is not torn off, the lower test probe 650 will be blocked by the release film 30 after it descends, and the test end 6521 of the probe body 652 will abut against the release film 30 above the hollow area 21 of the back glue 20. At this time, the sensing end 6520 of the probe body 652 rises and contacts the upper test probe 620, so that the test circuit 630 is turned on and sends a signal, then it is determined that the release film 30 has not been torn off.

[0095] It should be noted that there is a one-to-one correspondence between the upper test probes 620 and the lower test probes 650 , and the number of the upper test probes 620 and the lower test probes 650 corresponds to the number of the release films 30 to be torn off.

[0096] The automatic film tearing device provided in this embodiment also has the following advantages:

[0097] 1. It realizes automatic film tearing, film unloading and testing, with a high degree of automation, which can completely replace manual film tearing and improve production efficiency;

[0098] 2. It eliminates the problem of manual tearing of the circular release film 30, which may easily cause fingerprints and other dirt on the appearance;

[0099] 3. The six-axis robotic arm of the film-tearing robot 310 can imitate most of the human body's movements, with high flexibility, a large operating space range, and higher reliability.

[0100] It should also be noted that the entire operation process of the automatic film tearing device provided in the above-mentioned embodiment 1 and embodiment 2 is coordinated and controlled by the internal program of the control system.
