[0033] Embodiment: As Figures 1-4 shown, an intelligent watch earpiece film - tearing assisting device includes a film - tearing unit 10, a clamping unit 20, a linear cam unit 30 and a linear drive unit 40;

[0034] The linear drive unit 40 includes a base plate 41, a slide plate 44, and a micro lead screw motor 45. The micro lead screw motor 45 is installed on the base plate 41, and the micro lead screw motor 45 can drive the slide plate 44 to slide along the base plate 41;

[0035] The linear cam unit 30 includes a bearing bracket 31, a bearing module 32, a first rotating shaft 33, a flexible pressing plate 36, and a linear cam 37. The bearing bracket 31 is installed on the base plate 41. The linear cam 37 is installed on the slide plate 44. The first rotating shaft 33 is rotatably installed on the bearing bracket 31 through the bearing module 32, and the first rotating shaft 33 is slidably placed inside the linear cam 37. The flexible pressing plate 36 is fixed to the linear cam 37;

[0036] The film tearing unit 10 includes a first support frame 12, a clamping plate 13, and a first driving cylinder 15. The clamping plate 13 is fixed to the first support frame 12. The first driving cylinder 15 is installed on the first support frame 12 and the first driving cylinder 15 is connected to the clamping unit 20;

[0037] The clamping unit 20 includes a second support frame 21, a second driving cylinder 22, and a pressing plate 23. The second driving cylinder 22 is installed on the first support frame 12. The pressing plate 23 is fixed to the second support frame 21. The second driving cylinder 22 is connected to the second support frame 21 and can drive the second support frame 21 to move up and down.

[0038] The present invention is used for clamping and pasting film during the process of tearing the film of the smart watch earpiece, and includes a film tearing unit 10, a clamping unit 20, a linear cam unit 30, and a linear drive unit 40. The linear drive unit is used to drive the linear cam unit to move back and forth. The film tearing unit is installed on the robotic arm. The clamping unit 20 is installed on the film tearing unit. During operation, after the robotic arm controls the film tearing unit 10 to run to the preset position, the film on the earpiece is placed on the clamping plate 13. The second driving cylinder 22 drives the pressing plate 23 to move downward to clamp the film. Driven by the robotic arm, the clamping plate and the pressing plate drive the film to move upward to tear the film upward, exposing part of the product. Then, the micro lead screw motor 45 drives the linear cam unit 30 to move forward, so that the flexible pressing plate 36 presses the exposed product. The robotic arm drives the film tearing unit to move horizontally again to completely tear the film on the product. The present invention cooperates with the robotic arm to realize the segmented film tearing process of the film on the earpiece, effectively preventing a large amount of glue on the film from entering the earpiece and causing the earpiece to fail.

[0039] Such as Figure 1 and Figure 4As shown, two parallel slide rails 42 are provided on the bottom plate 41. The slide plate 44 is slidably connected to the slide rails 42 through sliders 43. The nut on the micro lead screw motor 45 is fixedly connected to the slide plate 44. A position sensor 46 is also provided on the bottom plate 41. The micro lead screw motor 45 is fixedly installed on the bottom plate 41. When the micro lead screw motor 45 drives the lead screw to rotate, the lead screw drives the nut to move linearly, thereby driving the slide plate 44 to move back and forth along the slide rails. The position sensor 46 is used to sense the position of the product.

[0040] As Figure 3 shown, the linear cam unit 30 further includes a second rotating shaft 34 and a cam bracket 35. The cam bracket 35 is fixedly installed on the slide plate 44. The linear cam 37 is rotatably installed on the cam bracket 35 through the second rotating shaft 34. A chute 38 is provided on one side of the linear cam 37. The first rotating shaft 33 is slidably placed in the chute 38.

[0041] The chute 38 has a three-section structure. The first-section chute and the third-section chute are horizontally arranged and the first-section chute is located below the third-section chute. The second-section chute is obliquely arranged and connected to the first-section chute and the third-section chute. A C-shaped snap ring 39 is installed between the linear cam 37 and the second rotating shaft 34. Initially, the first rotating shaft 33 is placed in the first-section chute. When the linear cam 37 moves linearly forward under the drive of the micro lead screw motor 45, the first rotating shaft 33 slides into the inclined second-section chute, applying a downward pressure to the flexible pressing plate 36 until the first rotating shaft slides into the third-section chute to press the product, i.e., the earphone tightly. By using the linear cam 37, the flexible pressing plate 36 is tilted downward while moving forward, thereby pressing and fixing the earphone firmly, facilitating that the product does not move during the second horizontal film tearing and preventing glue from entering the earphone during the film tearing process.

[0042] As Figure 2 shown, the film tearing unit 10 further includes a connecting cylinder 11. The connecting cylinder 11 is installed on the first support frame 12. The clamping plate 13 is fixedly installed at the lower end of the first support frame 12. A positioning hole 14 is provided on the clamping plate 13. The first driving cylinder 15 is horizontally fixed on the first support frame 12. The robotic arm is connected to the connecting cylinder 11. Therefore, the robotic arm can control the operation of the film tearing unit 10 and the clamping unit 20.

[0043] The second driving cylinder 22 is slidably mounted on the first support frame 12 through a support plate 25. A connecting block 26 is fixedly provided on the support plate 25. The piston rod of the first driving cylinder 15 is connected to the connecting block 26 and the first driving cylinder can drive the connecting block to slide back and forth. The support plate 25 is horizontally slidably mounted on the first support frame 12 through a sliding plate and a slide rail. When the first driving cylinder drives the connecting block to slide back and forth, the connecting block 26 drives the support plate and the clamping unit 20 to slide back and forth along the horizontal direction of the first support frame.

[0044] The second driving cylinder 22 is vertically arranged on the support plate 25, and the piston rod of the second driving cylinder is fixedly connected to the upper end of the second support frame 21. The pressing plate 23 is fixedly mounted on the lower end of the second support frame 21, and a positioning pin 24 capable of inserting into the positioning hole 14 is provided on the pressing plate 23. Therefore, the second driving cylinder 22 can drive the second support frame 21 to move up and down. When it is necessary to clamp the film, the second driving cylinder drives the second support frame 21 to move downward, and the positioning pin 24 just inserts into the positioning hole 14 on the clamping plate, and the clamping plate and the pressing plate clamp and fix the film; when the film is completely torn off, after the second driving cylinder 22 drives the second support frame 21 to move slightly upward, the first driving cylinder 15 drives the support plate to slide backward, and the pressing plate drives the torn-off film to run to the waste box, and the film is automatically thrown into the waste box.

[0045] The operation process of the present invention is as follows:

[0046] Step 1: The robotic arm is connected to the connecting cylinder 11. The linear driving unit 40 is mounted on the workbench. The robotic arm controls the film tearing unit 10 and the clamping unit 20 to run to the product on the workbench, and the film on the product is placed on the clamping plate 13 of the film tearing unit; the clamping unit 20 is mounted on the film tearing unit 10, and the film tearing unit is mounted on the robotic arm through the connecting cylinder 11. Therefore, the robotic arm can control the film tearing unit and the clamping unit to run together. The linear cam unit 30 is mounted on the linear driving unit 40, and the linear driving unit 40 is mounted on the preset position of the workbench through the bottom plate 41, so as to facilitate the linear cam unit 30 to act on the product on the workbench; initially, the product is completely covered by the film, and the area of the film is larger than the area of the product, and the part of the film exceeding the product is placed on the clamping plate.

[0047] Step 2: The second driving cylinder 22 drives the pressing plate 23 to move downward until the pressing plate 23 is pressed against the clamping plate 13 to clamp and fix the film on the product; the positioning pin 24 on the pressing plate just inserts into the positioning hole 14 on the clamping plate, further improving the firmness of the film fixation. Without moving the robotic arm, start the second driving cylinder 22 to run, and drive the second support frame 21 and the pressing plate 23 to move downward synchronously.

[0048] Step 3: The robotic arm drives the film tearing unit 10 and the clamping unit 20 to move upward to complete the first film tearing action. At this time, part of the product is exposed, and the flexible pressing plate 36 presses the exposed product under the action of the linear drive unit 40. Specifically, when the micro screw motor 45 drives the screw to rotate, the screw drives the nut to move linearly, and then drives the slide plate 44 to move back and forth along the slide rail. The slide plate drives the linear cam 37 to move back and forth, and the flexible pressing plate 36 moves forward and downward under the drive of the linear cam to press the product.

[0049] Step 4: The robotic arm drives the film tearing unit 10 and the clamping unit 20 to move forward. After the film is completely torn off, the robotic arm runs to the preset position again. The second driving cylinder 22 drives the pressing plate 23 to move upward. The pressing plate moves slightly upward to facilitate the sliding of the pressing plate relative to the clamping plate 13. The first driving cylinder 15 drives the support plate 25 to slide backward. The pressing plate 23 drives the torn film to run to the waste box and automatically throws the film into the waste box. Therefore, the whole film tearing process is divided into two steps: the first step is vertical film tearing, and the second step is horizontal film tearing. The two film tearing processes are both completed by the robotic arm driving the film tearing unit 10 and the clamping unit 20. After the first step of vertical film tearing is completed, part of the product, i.e., the earpiece, is exposed, but the film still covers the holes on the earpiece. At this time, if the film is torn vertically upward continuously, the glue is likely to fall into the holes of the earpiece. Therefore, the flexible pressing plate 36 is used to press the part of the product where the film has been torn off, and then the film is completely torn off horizontally by the robotic arm, effectively preventing the glue from falling into the holes of the earpiece and causing product failure.

[0050] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of this invention patent shall be subject to the appended claims.
