The three-axis driver is adapted to drive the rotating base to move laterally in the xy plane to tear the film after the tearing point is pressed onto the suction head. This invention uses a suction head to first pick up the tearing point, and then the pressure block presses the tearing point onto the suction head, thereby clamping the tearing point. Automatic film tearing can be achieved for tearing points of any angle or when the tearing point is close to the product and inconvenient to tear.

Description

Technical Field

[0001] This invention relates to the field of film tearing machine technology, and in particular to a single-line double-head film tearing machine. Background Technology

[0002] Currently, the production process for most products using adhesive tape is as follows: after the tape with a protective film is applied to the product, it enters a pressure-holding machine for a certain period of time, and then the product is removed from the pressure-holding machine and the protective film is peeled off. The protective film has an integrally formed edge with an outward-protruding tear handle. The tear handle refers to a small, non-adhesive area deliberately left on the protective film, which is easy for fingers or machines to grip.

[0003] A film-peeling machine is an automated device that removes the protective film from products. Currently, film-peeling machines on the market have requirements regarding the angle and position of the tearing handle. "Angle" refers to the orientation of the tearing handle relative to the periphery of the protective film. For example, the film-peeling machine can grip the tearing handle on one side of the protective film, but if the tearing handle is moved to the opposite side, the machine cannot grip it. "Position" refers to the distance between the tearing handle and the product. If the tearing handle is too close to the product, it will be difficult for the film-peeling machine to grip it. Unfavorable angles and / or unfavorable positions will affect the success rate of film peeling. Failed peeling requires manual removal of the film, significantly impacting production efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a single-line double-head film-tearing machine, which aims to enable the film-tearing machine to automatically tear film at any angle and position of the tearing hand.

[0005] To solve the above problems, the present invention provides a single-line double-head film-tearing machine, including a rotating base, a rotary driver, and a three-axis driver. The three-axis driver is used to drive the rotating base to move in the x, y, and z axes in space. The rotary driver is used to drive the rotating base to rotate around its own axis in a horizontal plane. A suction head, a pressure block, and a vertical driver are fixed on the rotating base. The suction head is located on the rotation axis of the rotating base and its bottom surface is used to hold the tearing hand position. The pressure block is located to the side of the suction head. The vertical driver is used to drive the pressure block to first descend below the tearing hand position and then rise to press the tearing hand position onto the suction head after the tearing hand position is held by the suction head. The three-axis driver is adapted to drive the rotating base to move laterally in the xy plane to tear the film after the tearing hand position is pressed onto the suction head.

[0006] Optionally, the pressure block is L-shaped and includes a fixing part and a functional part. The functional part is located at the bottom of the fixing part on the side facing the suction head, and the fixing part is fixedly connected to the vertical driver. The functional part is adapted to move downward to below the tearing position held by the suction head, and then move upward until it cooperates with the suction head to clamp the tearing position.

[0007] Optionally, the functional part is adapted to press against the bottom surface of the suction head when it moves upward; a horizontal driver is fixed on the rotating base, and the vertical driver is fixed on the horizontal driver; the horizontal driver is used to drive the functional part to move below the bottom surface of the suction head before the functional part moves upward.

[0008] Optionally, the upper surface of the functional part is provided with teeth.

[0009] Optionally, the functional part is adapted to move horizontally to press against the side of the suction head; a horizontal driver is fixed on the rotating base, and a vertical driver is fixed on the horizontal driver; the horizontal driver is used to drive the side of the functional part to press against the side wall of the suction head after the functional part finishes moving upward.

[0010] Optionally, the triaxial driver is adapted to drive the rotating seat to move upward a certain distance after the tearing hand position is pressed on the suction head before tearing the film.

[0011] Optionally, the rotating seat is adapted to drive the suction head to rotate a certain angle before tearing the film.

[0012] Optionally, the three-axis drive is provided with two rotating seats in parallel, the film tearing machine is provided with a conveyor line and two first product positioning fixtures located on both sides of the conveyor line, each of the first product positioning fixtures is used to support one end of two products in the same direction; there is a channel between the two first product positioning fixtures, the conveyor line is provided with a conveyor seat, the conveyor seat is provided with a lifting drive, the lifting drive is provided with a suction cup, and the channel is for the lifting drive to pass through.

[0013] Optionally, the film-tearing machine is provided with a pressure-holding mechanism and a pressure-holding station. The pressure-holding station is located on the conveying path of the conveyor line. Two second product positioning fixtures are provided on both sides of the conveyor line at the pressure-holding station. A channel is provided between the two second product positioning fixtures for the lifting drive to pass through. Each second product positioning fixture is used to support one end of two products in the same direction.

[0014] Optionally, two conveyor seats are spaced apart on the conveyor line, with the distance between them equal to the distance between the first product positioning fixture and the second product positioning fixture.

[0015] The technical solution of the present invention has the following advantages: 1. The suction head first picks up the tear-off area, and then the pressure block presses the tear-off area onto the suction head, thereby clamping the tear-off area. Automatic film tearing can be achieved when the tear-off area is close to the product and inconvenient to tear off. 2. The film-tearing mechanism is set on a rotating base. By rotating the film-tearing mechanism, automatic film tearing can be achieved at any angle of the tearing hand position. 3. The adoption of a double tearing station and a double pressure holding station improves work efficiency; 4. While using a conveyor line to transport products from the pressure holding station to the film tearing station, products can also be transported from other stations to the pressure holding station, thus improving the conveying efficiency.

[0029] Please refer to Figure 1 and Figure 2 This invention provides a single-line double-head film-tearing machine, including a rotating seat 1, a rotating driver 2, and a three-axis driver 3. The three-axis driver 3 is used to drive the rotating seat 1 to move in the x-axis, y-axis, and z-axis directions in space, and the rotating driver 2 is used to drive the rotating seat 1 to rotate around its own axis in the horizontal plane.

[0030] Please refer to Figure 2 The rotating base 1 is fixed with a suction head 4, a pressure block 5, and a vertical driver 6. The suction head 4 is vertically mounted on the rotation axis of the rotating base 1. The bottom surface of the suction head 4 is provided with suction holes for holding the tearing hand position. The pressure block 5 is located to the side of the suction head 4. The vertical driver 6 is used to drive the pressure block 5 to descend below the tearing hand position and then rise to press the tearing hand position onto the suction head 4 after the tearing hand position is held by the suction head 4. The three-axis driver 3 is adapted to drive the rotating base 1 to move laterally in the xy plane to tear the film after the tearing hand position is pressed onto the suction head 4.

[0031] Please refer to Figure 1 Specifically, the three-axis drive 3 includes an x-axis drive 31, a y-axis drive 32, and a z-axis drive 33, all preferably using linear guides, and each including a guide rail and a movable base; a bracket is fixedly mounted on the frame, the guide rail of the x-axis drive 31 is horizontally fixed to the bracket; the guide rail of the y-axis drive 32 is perpendicular to the guide rail of the x-axis drive 31, and the guide rail of the y-axis drive 32 is horizontally fixed to the movable base of the x-axis drive 31; the guide rail of the z-axis drive 33 is vertically fixed to the movable base of the y-axis drive 32; a rotary base 1 is fixed on the movable base of the z-axis drive 33, and the rotary base 1 is preferably disk-shaped; the rotary drive 2 is preferably a servo motor.

[0032] The working principle of the single-line double-head film-tearing machine proposed in this embodiment of the invention is as follows: the suction head 4 is moved to the position directly above the tearing handle by the x-axis driver 31 and the y-axis driver 32, and then the suction head 4 is lowered by the z-axis driver 33 so that the suction head 4 sucks the tearing handle. Then, the pressure block 5 is extended to the bottom of the tearing handle and then retracted and retracted to press the tearing handle onto the suction head 4 to achieve clamping. Finally, the protective film is torn off by moving the rotating seat 1 laterally.

[0033] In some cases, the tear handle is slightly upturned relative to the product, so when the suction head 4 descends to hold the tear handle, there is still space between the suction head 4 and the fixture for the pressure block to continue descending. In other cases, the tear handle is on the same plane as the product. In this case, when the suction head 4 descends to hold the tear handle, the pressure block cannot continue descending due to the obstruction of the fixture. In this case, some fixtures will have holes or slots to avoid the pressure block, allowing the pressure block to continue descending to complete its function. In the second case mentioned above, if the fixture is not designed to avoid the pressure block, then the suction head 4 needs to move upward a certain distance after holding the tear handle to provide space for the pressure block to descend.

[0034] Since the tear handle is a soft membrane, the pressure block can come into contact with the tear handle as it moves down to below it. During this contact, the pressure handle is deformed until the pressure block detaches from the tear handle. After detaching from the contact, the pressure block moves to below the tear handle.

[0035] Please refer to Figure 2 Specifically, the pressure block 5 is L-shaped and includes a fixing part 51 and a functional part 52. The functional part 52 is located at the bottom of the fixing part 51 on the side facing the suction head 4. The fixing part 51 is fixedly connected to the vertical driver 6. The functional part 52 is adapted to move downward to below the tearing position held by the suction head 4, and then move upward until it cooperates with the suction head 4 to clamp the tearing position.

[0036] Please refer to Figure 3Furthermore, a horizontal driver 8 is fixed on the rotating base 1, and a vertical driver 6 is fixed on the horizontal driver 8. The horizontal driver 8 is used to press the opposing sidewalls of the functional part 52 and the suction head 4 together (see...). Figure 4 Alternatively, the horizontal actuator 8 moves the functional unit 52 to the projection range directly below the bottom surface of the suction head 4, and then the vertical actuator 6 drives the functional unit 52 upward, so that the upper surface of the functional unit 52 presses against the bottom surface of the suction head 4 (see...). Figure 5 ).

[0037] Both the horizontal actuator 8 and the vertical actuator 6 are preferably cylinders, such as precision slide cylinders. The horizontal actuator 8 is fixed to the bottom of the rotary seat 1, and a mounting plate is fixed to the piston rod of the horizontal actuator 8. The vertical actuator 6 is fixed to the mounting plate. Studs 7 can be provided on both the rotary seat 1 and the mounting plate (see...). Figure 2 The cylinder is used to limit the stroke of the cylinder. When the moving part of the cylinder reaches the limit position, it is blocked by the stud 7. The stroke is finely adjusted by rotating the stud 7.

[0038] There are two scenarios where the functional unit 52 and the suction head 4 work together to hold the tear-off hand position: Please refer to Figure 4 In the first case, the functional unit 52 is never within the orthographic projection range of the bottom surface of the suction head 4 when it moves; the functional unit 52 first moves downward to below the tearing position 201, and then moves upward to the upper surface being higher than the bottom surface of the suction head 4. Then the horizontal driver 8 drives the side of the functional unit 52 to press the tearing position 201 onto the side wall of the suction head 4.

[0039] Please refer to Figure 5 In the second case, the upper surface of the functional part 52 is adapted to press against the bottom surface of the suction head 4 when it moves upward. That is, a part of the functional part 52 is always within the orthographic projection range of the bottom surface of the suction head 4. First, the bottom surface of the suction head 4 holds the tearing position 201, then the functional part 52 moves down to below the tearing position 201, then the horizontal driver 8 drives the functional part 52 to move closer to the suction head 4, and finally the functional part 52 moves back upward, pressing the tearing position 201 against the bottom surface of the suction head 4. In this case, teeth 521 can be provided on the upper surface of the functional part 52 to increase the static friction when the upper surface of the functional part 52 presses against the tearing position 201.

[0040] To further improve the film-tearing efficiency, after the tearing handle 201 is pressed onto the suction head, the three-axis driver 3 can be used to drive the rotating seat 1 to move upward a certain distance before tearing the film. The purpose is to separate the tearing handle 201 from the protective film 200 to create a gap for subsequent rapid film tearing. Alternatively, before tearing the film, the rotating seat 1 can be used to drive the suction head 4 to rotate at a certain angle. Since the tearing handle 201 is clamped on the suction head 4, the tearing handle 201 will not fall off when the suction head 4 rotates. When the suction head 4 drives the tearing handle 201 to rotate, it will pull the tearing handle 201 to separate the tearing handle 201 from the protective film 200 to create a gap for subsequent rapid film tearing.

[0041] Please refer to Figure 1 Furthermore, the three-axis drive 3 is provided with two parallel rotating seats 1, and the film tearing machine is provided with a conveyor line 9 and two first product positioning fixtures 10 located on both sides of the conveyor line 9. Each first product positioning fixture 10 is used to support one end of two products 100 in the same direction. Figure 6 The dashed box represents product 100). A channel 11 is provided between the two first product positioning fixtures 10. A conveyor seat 17 is provided on the conveyor line 9. A lifting driver 12 is provided on the conveyor seat 17. A suction cup 13 is provided on the lifting driver 12. The channel 11 allows the lifting driver 12 to pass through. The lifting driver 12 is preferably a cylinder arranged vertically upwards. The lifting driver 12 picks up the product at the previous station through the suction cup 13 and is conveyed to the two first product positioning fixtures 10 at the film-tearing station under the drive of the conveyor line 9. Then, by lowering the lifting driver 12 and controlling the suction cup 13 to stop picking up the product, the product is left on the first product positioning fixture 10 so that the film-tearing mechanism composed of the suction head 4 and the pressure block 5 can tear off the protective film on the product.

[0042] To further improve the working efficiency of the equipment, the single-line double-head film-tearing machine proposed in this embodiment of the invention also integrates a pressure-holding function: the film-tearing machine is equipped with a pressure-holding mechanism 14 and a pressure-holding station 15. The pressure-holding station 15 is located on the conveying path of the conveyor line 9. Two second product positioning fixtures 16 are provided on both sides of the conveyor line 9 on the pressure-holding station 15. A channel 11 is provided between the two second product positioning fixtures 16 for the lifting drive 12 to pass through. Each second product positioning fixture 16 is used to support one end of two products in the same direction. Two conveyor seats 17 are provided at intervals on the conveyor line 9. The interval distance is equal to the distance between the first product positioning fixture 10 and the second product positioning fixture 16. While the conveyor line 9 is conveying products from the pressure-holding station 15 to the film-tearing station, products can be conveyed from other stations to the pressure-holding station 15, which improves the conveying efficiency.

[0043] The workflow of the single-line double-head film-tearing machine with pressure-holding function proposed in this embodiment of the invention is as follows: the conveyor seat 17 picks up the product from the upstream equipment, the conveyor seat 17 places the product to the pressure-holding station 15, the pressure-holding mechanism 14 holds the auxiliary materials on the product, the conveyor seat 17 transports the pressure-held product to the film-tearing station, the film-tearing mechanism tears the film (the torn film is thrown into the waste discharge area), and the finished product is taken away by the downstream.

[0044] The aforementioned single-line double-head film-tearing machine uses a suction head 4 to first pick up the tearing handle, and then a pressure block presses the tearing handle onto the suction head 4, thereby clamping the tearing handle. This allows for automatic film tearing when the tearing handle is close to the product and inconvenient to tear. The film-tearing mechanism is set on a rotating seat 1. By rotating the film-tearing mechanism on the rotating seat 1, automatic film tearing can be achieved for tearing handles at any angle. The use of double film-tearing stations and double pressure-holding stations 15 improves work efficiency.

[0045] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
