[0057] like Figure 1 As shown, a film peeling device for a sheet after it has been applied includes a first support 1, a linear module 2 is provided on the first support 1, a second support 3 is fixedly provided on the slider of the linear module 2, and a cylinder 4 is provided on the second support 3.

[0058] The direction of movement of the slider in the linear module 2 is perpendicular to the direction of extension and retraction of the piston rod of the cylinder 4;

[0059] The piston rod of cylinder 4 is provided with a film-removing head at its end;

[0060] like Figure 2-3As shown, the film-removing head includes a film-removing head bracket 5, on which a pressure roller assembly 6 is provided for pressing the tape toward the film sheet to be removed. On one side of the film-removing head bracket 5, a tape shaft assembly 7 is provided for placing the tape roll. On the other side of the film-removing head bracket 5, an anvil 8 is provided. On the anvil 8, a vacuum nozzle 9 is provided for sucking up the tape covering the anvil 8. On the film-removing head bracket 5 between the pressure roller assembly 6 and the tape shaft assembly 7, an air knife 10 is provided for blowing the tape toward the pressure roller assembly 6.

[0061] The tape-removing head support 5 is equipped with a cutter assembly 11 that can rotate to the position of the cutting board 8 to cut the tape.

[0062] Preferably, the film-removing head support 5 includes two parallel support plates 51, and two joint bearings 12 are provided on each of the opposite end faces of the two support plates 51. The rod end of the joint bearing 12 is connected to the adjusting rod 13, and the other end of the adjusting rod 13 is connected to the fixing plate 14. The fixing plate 14 is fixedly connected to the end of the piston rod of the cylinder 4.

[0063] The fixing plate 14 is provided with a strip hole 141 adapted to the movement of the adjusting rod 13; specifically, the end of the adjusting rod 13 is provided with a limiting block to prevent the adjusting rod 13 from coming out of the strip hole 141;

[0064] An adjusting spring 15 is fitted on the adjusting rod 13 between the fixed plate 14 and the corresponding joint bearing 12.

[0065] In this application, the adjusting rod 13, the joint bearing 12, and the adjusting spring 15 form a suspended connection structure, which enables the film peeling head to achieve three-dimensional posture adjustment and has a certain floating ability to adapt to the film peeling operation on the film sheet at different positions and different application angles.

[0066] Preferably, the pressure roller assembly 6 includes a pressure roller 61, and pressure roller shafts 62 are coaxially fixed at both ends of the pressure roller 61.

[0067] The pressure roller 61 is located between two support plates 51, and the pressure roller shaft 62 is adapted to the pressure roller hole 52 on the corresponding side support plate 51. The pressure roller shaft 62 is vertically provided with a pressure roller column 63. The support plate 51 is provided with a pressure roller block 64 for sliding cooperation with the pressure roller column 63. A compression spring is sleeved on the pressure roller column 63 between the pressure roller block 64 and the pressure roller shaft 62. The compression spring is not shown in the figure. Specifically, the end of the pressure roller column 63 away from the pressure roller shaft 62 is provided with a pressure roller limiting block to prevent the pressure roller column 63 from falling off the pressure roller block 64.

[0068] The pressure roller hole 52 has an elongated structure to accommodate the movement of the pressure roller shaft 62 along the axial direction of the pressure roller column 63.

[0069] This application, through the cooperation of the pressure roller shaft 62 and the pressure roller hole 52, the cooperation of the pressure roller column 63 and the pressure roller block 64, and the setting of the pressure spring, enables the pressure roller 61 to have the pressure to press the tape onto the film sheet to be peeled, and at the same time enables the pressure roller 61 to have a certain floating ability. With the three-dimensional posture adjustment of the peeling head, it can adapt to the film peeling operation on the film sheet at different positions and angles.

[0070] Preferably, the tape shaft assembly 7 includes a tape shaft cylinder 71 fixed to the outside of one of the support plates 51, and a tape shaft 72 is fixedly mounted at the end of the telescopic rod of the tape shaft cylinder 71, such as... Figure 4-6 As shown, a tapered sleeve 73 is coaxially fixed at the end of the tape shaft 72 away from the tape shaft cylinder 71, and the small end of the tapered sleeve 73 is adapted to be connected to the end of the tape shaft 72.

[0071] A claw assembly is coaxially fixed to the outside of the tape shaft 72. The claw assembly includes several claw plates 74 evenly distributed along the circumferential direction. Claws 75 are arranged on the radially outer side of the claw plate 74 near the end of the conical sleeve 73. The end of the claw plate 74 away from the conical sleeve 73 is fixedly connected to the support plate 51 on the corresponding side.

[0072] Specifically, the maximum diameter of the radial outer wall surface of the conical sleeve 73 is smaller than the diameter of the inner wall surface of the tape roll;

[0073] The radial outer wall of the claw 75 has a frustum structure, and the small end of the radial outer wall of the claw 75 faces the tapered sleeve 73 to facilitate the installation of the tape roll.

[0074] In the natural state of the claw assembly, the minimum diameter of the radial outer wall surface of the claw 75 is smaller than the diameter of the inner wall surface of the tape roll, the maximum diameter of the radial outer wall surface of the claw 75 is larger than the diameter of the inner wall surface of the tape roll, and the maximum diameter of the radial outer wall surface of the claw plate 74 is smaller than the diameter of the inner wall surface of the tape roll.

[0075] When the tape shaft cylinder 71 drives the tape shaft 72 to move, the tapered sleeve 73 achieves locking between the claw assembly and the tape roll by radially tightening the claw assembly.

[0076] In this application, when installing the tape roll, the tape shaft cylinder 71 controls the tape shaft 72 to extend so that the conical sleeve 73 does not contact the claw assembly. After the tape roll passes through the conical sleeve 73, it compresses the claw 75 along the frustum structure of the radial outer wall of the claw 75 until it is fitted outside the claw assembly. Then the claw 75 is opened and reset. At this time, the tape roll can rotate on the claw assembly, while the claw 75 prevents the tape roll from falling off the claw assembly.

[0077] When it is necessary to lock the tape roll so that it cannot rotate, the tape shaft cylinder 71 controls the tape shaft 72 to retract, causing the conical sleeve 73 to expand radially outward to tighten the end of the jaw 75 in the jaw assembly, thereby tightening the jaw plate 74 on the inner wall of the tape roll to lock the tape roll.

[0078] Preferably, the film-removing head bracket 5 is equipped with a proximity switch capable of detecting the remaining tape on the tape roll. When the tape on the roll is about to run out, the proximity switch outputs an alarm signal so that the tape roll can be replaced in time. The selection of the proximity switch's installation position and the detection principle are existing technologies and will not be described in detail here.

[0079] Preferably, a channel plate 53 is fixedly provided on the film-removing head bracket 5 between the pressure roller assembly 6 and the tape shaft assembly 7. The end face of the channel plate 53 facing the adhesive side of the tape is coated with an anti-stick coating to prevent the adhesive side from sticking.

[0080] The air knife 10 is fixedly mounted on the channel plate 53. The air knife 10 has 20 micro-holes arranged in a straight line. The air outlet of the air knife 10 faces the pressure roller 61, which can blow the tape toward the pressure roller 61 and better cover the surface of the pressure roller 61. The air inlet of the air knife 10 is connected to the air source.

[0081] Preferably, a straight support 81 is fixedly installed on the back plate of the cutting board 8, and a vacuum nozzle 9 is installed on the straight support 81. Specifically, the vacuum nozzle 9 is connected to the pagoda head.

[0082] During installation, the position of the straight bracket 81 is adjusted to ensure that the vacuum nozzle 9 can grip the tape, thereby ensuring the accuracy of the film peeling position and the continuity of the next film peeling.

[0083] Preferably, the cutter assembly 11 includes a rotary cylinder 111 disposed between two support plates 51. The ends of the two output shafts of the rotary cylinder 111 pass through the corresponding support plates 51 and are vertically fixedly connected to one end of a rotating arm 112. A cutter holder 113 is vertically disposed between the other ends of the two rotating arms 112, and a cutter 114 is disposed on the cutter holder 113. Specifically, the two output shafts of the rotary cylinder 111 are rotatably engaged with the corresponding support plates 51.

[0084] like Figure 7 As shown, the cutter holder 113 is provided with a cutting blade 114 at one end, which is slidably fitted with a material ejector plate 115. The material ejector plate 115 is provided with a straight groove channel 116 adapted to the cutting blade 114 passing through.

[0085] A cutting spring 117 is provided between the ejector plate 115 and the cutter holder 113, and the direction of the spring force of the cutting spring 117 is consistent with the sliding direction of the ejector plate 115.

[0086] The surface of the ejector plate 115 is coated with an anti-stick coating to prevent the adhesive surface from sticking together.

[0087] In this application, after the cutter assembly 11 is reset, its position is between the air knife 10 and the tape shaft assembly 7. When the tape needs to be cut, the rotary cylinder 111 drives the rotating arm 112 to move the knife holder 113, the cutter 114, and the ejector plate 115 toward the anvil plate 8. When pressing against the anvil plate 8, the ejector plate 115 slides toward the knife holder 113 until the cutter 114 contacts the anvil plate 8 and cuts the tape covering the anvil plate 8. Then, the rotary cylinder 111 controls the cutter assembly 11 to rotate and reset. During the rotation, the ejector plate 115 is slid outward and reset under the action of the cutter spring 117. During the reset process, the ejector plate 115 separates the cutter 114 from the cut tape, ensuring that the cut tape does not stick to the cutter 114.

[0088] Preferably, the tool holder 113 is provided with a ventilation hole 118, which is connected to an air source;

[0089] After the cutter assembly 11 is rotated to the position of the cutting board 8, the air outlet end of the ventilation hole 118 faces the cutting board 8.

[0090] In this application, after the cutter 114 cuts the tape, the vent 118 blows air towards the cutting board 8, further ensuring that the cut tape does not stick to the cutter 114.

[0091] A film peeling device for sheet coating after sheet application, the specific implementation of which is as follows:

[0092] In practical use, the film-removing device of this application can be mounted on an existing movable robotic arm.

[0093] Before using the film-removing device of this application, the tape roll is installed on the tape shaft assembly 7 without being locked. The tape is pulled out so that it passes around the pressure roller assembly 6 and reaches the anvil 8 position. The non-adhesive side of the tape faces the pressure roller assembly 6 and ventilates into the air knife 10 and the ventilation hole 118. The air blown out by the air knife 10 causes the tape to wrap around the pressure roller 61. Then the tape roll is locked on the tape shaft assembly 7.

[0094] When film removal is required, the robotic arm moves the film removal device to the vicinity of the film to be removed. Then, the linear module 2 and cylinder 4 work together to press the pressure roller 61, which is wrapped with adhesive tape, onto the edge of the film. After a 2-second wait to ensure the pressure roller 61 is fully compacted, the air knife 10 and ventilation holes 118 stop blowing air, releasing the locking relationship between the tape roll and the tape shaft assembly 7. The linear module 2 and cylinder 4 then work together to move the film removal head along the direction of tape pulling from the tape roll. During this movement, the tape is compacted and adhered to the film to be removed. Afterwards, the linear module 2 and cylinder 4 quickly reset, and during the pulling of the tape, the adhesive tape is removed from the film. The adhesive film is peeled off the sheet; then ventilation is introduced into the air knife 10 and the ventilation hole 118. The air blown out by the air knife 10 causes the tape to wrap around the pressure roller 61. The vacuum nozzle 9 is activated to pick up the tape, so that the tape covers the anvil 8 and locks the tape roll onto the tape shaft assembly 7. Then, the rotary cylinder 111 controls the cutter assembly 11 to rush toward the anvil 8 and cuts off the tape with the adhesive film through the cutter 114. Then the cutter assembly 11 rotates back to reset. Under the dual action of the ejector plate 115 and the ventilation hole 118, it is ensured that the cut tape does not stick to the cutter 114. After the cutter assembly 11 resets, one film peeling operation is completed.

[0095] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, they are not intended to limit the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the protection scope of the present invention.
