Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical automation field especially relates to a rotary film tearing mechanism. BACKGROUND

[0002] When hot melt adhesive is used for processing and treatment of electronic products, a layer of release film is usually adhered to the surface of the hot melt adhesive; when the attaching process is carried out, the release film on the surface of the hot melt adhesive needs to be torn off; however, manually tearing the release film will leave fingerprints or scratches on the surface of the product, which is not conducive to the production and assembly of electronic products.

[0003] Therefore, a rotary clamping glue tearing mechanism is disclosed in Chinese Patent No. 202022671987.3, which includes a linear slide module, a glue tearing bottom plate connected to the linear slide module, a glue tearing support plate installed on the glue tearing bottom plate, a rotating motor installed on the rear side of the glue tearing support plate, a rotating plate installed at the front end of the rotating motor and passing through the glue tearing support plate, a clamping jaw cylinder installed at the front end of the rotating plate, and a clamping jaw slidably installed at the front end of the clamping jaw cylinder.

[0004] When tearing off the release film using the film tearing mechanism provided by the prior art, if it is necessary to automatically tear the film of electronic products on the assembly line, the clamping jaw needs to be repeatedly slid on the linear slide module; however, the clamping jaw cannot achieve precise movement on the linear slide module. Since the stagnation position of the clamping jaw affects the position of the clamping jaw clamping the release film, if the stagnation position of the clamping jaw is relatively far from the electronic product, the clamping jaw may not be able to clamp or only clamp part of the release film, thereby reducing the film tearing efficiency and film tearing precision of the film tearing mechanism.

The clamping jaw can achieve precise movement on the linear slide module, thereby improving the film tearing efficiency and film tearing precision of the film tearing mechanism.

[0006] To achieve the above purpose, the utility model adopts the technical scheme of:

[0007] The rotary film tearing mechanism provided by the utility model includes a film tearing mechanism, a vertical movement mechanism, and a reset detection assembly.

[0008] The film tearing mechanism comprises a first driving mechanism, a second driving mechanism and a clamping jaw; the clamping jaw is horizontally arranged; the second driving mechanism drives the clamping jaw to clamp or open; and the first driving mechanism drives the clamping jaw to rotate.

[0009] The vertical moving mechanism drives the clamping jaw to move in the vertical direction.

[0010] The reset detection assembly comprises a plurality of photoelectric sensors and a light blocking sheet; the light blocking sheet moves along with the clamping jaw in the vertical direction; all the photoelectric sensors are arranged in the vertical direction; the emitter of the photoelectric sensor and the receiver of the photoelectric sensor are oppositely arranged; the center of the emitter of the photoelectric sensor and the center of the receiver of the photoelectric sensor are connected to form a first straight line; the first straight line is horizontally arranged; the plane of the light blocking sheet is perpendicular to the first straight line; and the light blocking sheet is located between the emitter of the photoelectric sensor and the receiver of the photoelectric sensor.

[0011] The photoelectric sensor is electrically connected with the vertical moving mechanism.

[0012] The rotating film tearing mechanism, preferably, the first driving mechanism is a rotating air cylinder; the second driving mechanism is a pneumatic finger; the pneumatic finger is fixed on the rotating table of the rotating air cylinder; the axis of the rotating table of the rotating air cylinder is parallel to the extension line of the parallel clamping fingers of the pneumatic finger.

[0013] The clamping jaw comprises a fixed part, an extension part and a contact part; the opposite side of the parallel clamping fingers of the pneumatic finger is regarded as the inner side; the fixed part is fixed on the outer side of the parallel clamping fingers of the pneumatic finger; the extension part is fixed with the fixed part; one end of the parallel clamping fingers of the pneumatic finger connected with the body of the pneumatic finger is regarded as the bottom of the parallel clamping fingers of the pneumatic finger, and the extension part is attached to the top of the parallel clamping fingers of the pneumatic finger; the extension part extends to the inner side of the parallel clamping fingers of the pneumatic finger; the contact part is fixed with the extension part; the contact part is in the form of a plate; the plate surface of the contact part is parallel to the inner side surface of the parallel clamping fingers of the pneumatic finger; and the contact part is located on the inner side of the parallel clamping fingers of the pneumatic finger.

[0014] The rotating film tearing mechanism, preferably, the vertical moving mechanism is a lead screw sliding table; the lead screw sliding table is vertically arranged; the rotating air cylinder is fixed on the sliding seat of the lead screw sliding table; and the light blocking sheet is fixed on the sliding seat of the lead screw sliding table.

[0015] The rotary film-tearing mechanism provided by this utility model preferably further includes a mounting plate and a reinforcing rib; the mounting plate is vertically arranged; the lead screw slide, the photoelectric sensor and the reinforcing rib are all fixed on the same surface of the mounting plate; the lead screw slide is located between the photoelectric sensor and the reinforcing rib.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] The rotary film-tearing mechanism provided by this utility model includes a film-tearing mechanism and a vertical moving mechanism. The film-tearing mechanism includes a first driving mechanism, a second driving mechanism, and a gripper. The vertical moving mechanism controls the gripper to move vertically, thereby controlling the gripper to descend to the film-tearing area or to return to its original position, preventing the gripper from occupying the loading space when it is stuck in the film-tearing area, thus affecting the loading efficiency of electronic products placed on the work platform. The first and second driving mechanisms control the gripper to complete the operation of gripping and tearing the release film, realizing the control of the gripper to clamp the release film and rotate to tear the film, improving the film-tearing efficiency and avoiding... Manual removal of the release film may leave fingerprints or scratches on the product surface. Furthermore, it includes a reset detection component, which comprises several photoelectric sensors and a light-blocking plate. Since the stopping position of the grippers affects the position where they grasp the release film, if the stopping position is far from the electronic product, the grippers may fail to clamp the film properly or only partially clamp it, thus reducing the tearing efficiency and accuracy of the film-tearing mechanism. The vertical movement mechanism cannot move the grippers precisely, which may cause them to deviate from the appropriate stopping position. Therefore, all photoelectric sensors are distributed vertically. The light-blocking plate moves vertically along with the gripper, and the stop position of the gripper is controlled by a photoelectric sensor. Specifically, the light-blocking plate is located between the emitter and receiver of the photoelectric sensor, with the emitter and receiver facing each other. The center of the emitter and receiver of the photoelectric sensor form a first straight line, which is horizontal and perpendicular to the moving direction of the light-blocking plate. This allows the light-blocking plate to block the light emitted by the emitter of the photoelectric sensor when it moves. Furthermore, the plane of the light-blocking plate is perpendicular to the first straight line to increase the recognition rate when the light-blocking plate passes the photoelectric sensor. When the light-blocking plate moves with the gripper to the photoelectric sensor at a preset point, the light-blocking plate blocks the light emitted by the emitter of the photoelectric sensor. The photoelectric sensor controls the vertical moving mechanism to stop driving the gripper to continue moving, allowing the gripper to stop precisely at that position, thus preventing the gripper from being taken to a deviated position by the vertical moving mechanism. Furthermore, multiple photoelectric sensors are set in the same vertical direction, which can be used for gripper reset or to record the tearing areas of multiple different electronic products to improve the efficiency of automated film tearing.

[0018] In use, if the electronic product on the assembly line needs to be automatically stripped of the film, the gripper needs to be repeatedly slid on the linear slide module to free up the space for loading and unloading the electronic product, but the gripper cannot be accurately moved on the linear slide module, and the stop position of the gripper affects the position of the gripper clamping the release film, if the stop position of the gripper is far from the electronic product, the gripper may not be clamped or only part of the release film is clamped, thereby reducing the film stripping efficiency and film stripping accuracy of the film stripping mechanism; therefore, the rotating film stripping mechanism is provided, the photoelectric sensor is arranged in the vertical direction by increasing the reset detection assembly, the light barrier plate moves with the gripper, the stop position of the gripper is controlled by the light barrier plate shielding the photoelectric sensor, thereby realizing accurate movement of the gripper on the linear slide module, and improving the film stripping efficiency and film stripping accuracy of the film stripping mechanism.

[0032] The rotating film tearing mechanism provided by the embodiment 1 of the utility model, including film tearing mechanism 1 and vertical moving mechanism 2, film tearing mechanism 1 includes first drive mechanism 11, second drive mechanism 12 and jaw 13, through vertical moving mechanism 2 control jaw 13 moves in vertical direction, thereby control jaw 13 drops to film tearing area or resets, avoid jaw 13 stagnation in film tearing area and occupy feeding space to thereby influence the feeding efficiency of electronic product placement on work platform, through first drive mechanism 11 and second drive mechanism 12 control jaw 13 complete the operation of clamping release film and tearing film, realize control jaw 13 clamps release film and rotates tearing film, improve tearing film efficiency, avoid artificial tearing release film and leave fingerprint or scratch mark on product surface, further, still include reset detection assembly 3, reset detection assembly 3 includes several photoelectric sensors 31 and light barrier 32, because the stagnation position of jaw 13 influences the position of jaw 13 clamping release film, if jaw 13 stagnation position is farther compared with electronic product, possibly lead to jaw 13 unable to clamp or only clamp part release film, thereby reduce the tearing film efficiency and tearing film precision of film tearing mechanism 1, and vertical moving mechanism 2 cannot make jaw 13 accurately move, thereby possibly lead to jaw 13 deviate from the suitable stagnation position, for this, distribute all photoelectric sensors 31 along vertical direction, and make light barrier 32 follow jaw 13 and move in vertical direction, control the stop position of jaw 13 through photoelectric sensor 31, specifically, light barrier 32 is located between the transmitter of photoelectric sensor 31 and the receiver of photoelectric sensor 31, make the transmitter of photoelectric sensor 31 and the receiver of photoelectric sensor 31 set towards each other, the center of the transmitter of photoelectric sensor 31 and the center of the receiver of photoelectric sensor 31 are connected into first straight line, first straight line is horizontally arranged, first straight line is perpendicular to the moving direction of light barrier 32, thereby can make light barrier 32 shield the light emitted by the transmitter of photoelectric sensor 31 when moving, further, make the plane of light barrier 32 be perpendicular to first straight line, increase the identification rate of light barrier 32 when passing through photoelectric sensor 31, when light barrier 32 follows jaw 13 and moves to the photoelectric sensor 31 of preset point, light barrier 32 shields the light emitted by the transmitter of photoelectric sensor 31, photoelectric sensor 31 controls vertical moving mechanism 2 and stops driving jaw 13 to continue moving, can make jaw 13 accurately stagnate in this position, thereby avoid jaw 13 being taken to deviated position by vertical moving mechanism 2, further, set multiple photoelectric sensors 31 on the same vertical direction, can be used for jaw 13 reset or record the film tearing area of multiple different electronic products, to improve the efficiency of automatic tearing film,

[0033] In use, if the electronic product on the assembly line needs to be automatically stripped of the film, the gripper 13 needs to be repeatedly slid on the linear slide module to free up the space for loading and unloading the electronic product. However, the gripper 13 cannot be accurately moved on the linear slide module. The stop position of the gripper 13 affects the position of the gripper 13 clamping the release film. If the stop position of the gripper 13 is far from the electronic product, the gripper 13 may not be able to clamp or only clamp part of the release film, thereby reducing the film stripping efficiency and film stripping accuracy of the film stripping mechanism. Therefore, the rotating film stripping mechanism provided by the embodiment 1 of the utility model is used. The photoelectric sensor 31 is arranged along the vertical direction by increasing the reset detection assembly 3. The light barrier 32 moves with the gripper 13. The stop position of the gripper 13 is controlled by the light barrier 32 shielding the photoelectric sensor 31, so as to realize the accurate movement of the gripper 13 on the linear slide module and improve the film stripping efficiency and film stripping accuracy of the film stripping mechanism 1.

The rotary seat in the rotary cylinder with high torsion force corresponds to the rotary table 111 of the rotary cylinder in the rotating film stripping mechanism. The second driving mechanism 12 is a pneumatic finger. The pneumatic finger uses a high-precision double-guide-rail gripper cylinder provided by a patent with the Chinese patent application number 202222011066.3.
