Description

Technical Field

[0001] This utility model relates to the field of film cutting and feeding in string welding machines, and specifically to a film cutting mechanism in a film coating equipment. Background Technology

[0002] In the production of solar cell modules, after the cells are thinned, they are directly connected to each other at high temperature and welded into strings using traditional welding strips. To reduce the breakage rate of the solar cell modules, a coating layer needs to be laid on the modules. In the existing coating processing industry, the film-cutting equipment is an indispensable and important component. Traditional film-cutting structures generally have some technical problems and limitations. For example, Chinese invention patent application, application number: CN202420763303.8, entitled "A Photovoltaic Film Cutting Device", usually has a fixed lifting adjustment of the blade, or the film-cutting size is fixed and single, and the applicable product types are limited. The lifting of the blade cannot be accurately and dynamically adjusted according to the change of the coating height, thus affecting the cutting quality. Utility Model Content

[0003] To address the issues of limited film size and few applicable products resulting from the film-cutting machine, this invention proposes a film-cutting mechanism in a film-coating device. The mechanism comprises a drive center, a film-cutting component, and a supporting structure. The supporting structure includes a first track, a device, and a support plate. The top of the lifting device is fixedly installed at the bottom of the first track. The support plate is fixedly connected to the bottom of the lifting device. The film-cutting component is movably connected to the supporting structure via the first track. The drive center drives the supporting structure to move.

[0004] By setting the film-cutting assembly to move along the first track, the drive center drives the supporting structure to move, thereby achieving the separation of the film-cutting assembly from the coating.

[0005] Specifically, the lifting device includes a lifting cylinder and a lead screw. The lifting cylinder drives the film-cutting assembly to achieve linear lifting motion.

[0006] By adjusting the height of the film-cutting assembly using a lifting cylinder, separation of films at different heights can be achieved.

[0007] Specifically, the film-cutting assembly includes a blade, a positioning pin, a connecting plate, and a slider. The connecting plate is fixedly mounted on the slider via the positioning pin, and the blade is vertically mounted on the slider via the connecting plate.

[0008] The connecting plate secures the blade and slider, increasing the stability of the blade during the film-cutting process.

[0009] Preferably, the film-cutting assembly further includes a locking member, which is fixedly connected to the slider, and the locking member fixes and locks the slider to the first track.

[0010] By installing locking components on the slider to secure it to the first track, the film-cutting assembly is prevented from falling off or separating from the first track during the film-cutting process due to insufficient fastening.

[0011] Specifically, the drive center includes a drive unit, a second track, and a mounting bracket. The drive center is fixedly connected to the mounting bracket, the second track is fixedly installed on the mounting bracket, and the support plate is movably connected to the second track.

[0012] Preferably, the drive unit includes a motor, a drive pulley, a synchronous belt, and a driven pulley. The motor is mounted on a mounting bracket, and the drive pulley and...

[0013] The motor is connected to the bottom, the driven wheel is mounted on the mounting bracket, the motor is connected to the driven wheel via a synchronous belt, and the synchronous belt is connected to the support plate.

[0014] The motor drives the drive wheel to rotate via a synchronous belt, which in turn moves the load-bearing structure, thereby achieving the separation of the film from the film-coating assembly.

[0015] Specifically, below the second track, in the direction of its extension, there are a first detection switch, a second detection switch, and a third detection switch.

[0016] By setting a detection switch to control the direction of motor rotation, the direction of movement of the load-bearing structure via the slider on the second track is controlled, thereby maintaining the stability of equipment operation and increasing the film-cutting efficiency of the film-cutting assembly.

[0017] Preferably, the mounting bracket is also provided with limiting blocks, which are located at both ends of the second track.

[0018] Specifically, the bottom of the support plate is equipped with a stop block, which is set to correspond to the limit block, and the stop block moves between the two limit blocks.

[0019] By setting two sets of limit blocks to restrict the movement of the stop blocks, the movement distance of the bearing structure can be limited within a preset range, thus maintaining the stability of the membrane cutting mechanism.

[0020] The film-cutting assembly is driven by a lifting cylinder to make vertical linear motion. The distance between the sliders of the film-cutting assembly is manually adjusted by the first track. The motor drives the bearing structure to move vertically relative to the second track, thereby moving the film-cutting assembly and realizing the division of the film by the blade in the film-cutting assembly. This solves the problems of fixed blade lifting and adjustment and fixed film-cutting size in traditional film-cutting equipment. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] This utility model proposes a film-spreading mechanism in a film-coating device, including a drive center, a film-spreading component 001, and a supporting structure; the supporting structure includes a first track 002, a lifting device, and a support plate. The top of the lifting device is fixedly installed at the bottom of the first track 002, and the support plate is fixedly connected to the bottom of the lifting device. The film-spreading component 001 is movably connected to the supporting structure through the first track 002, and the drive center drives the supporting structure to move along a direction perpendicular to the first track 002.

[0030] To ensure the stability of the film during the film-cutting process, the lifting device first drives the support plate to complete the lifting motion according to the film height. The film-cutting component 001 is manually adjusted by the slider 013 moving on the first track 002, and the drive center drives the bearing structure to move on the second track 003, so as to realize the separation of the film-cutting component 001 from the film.

[0031] The lifting device uses a lifting cylinder 004. The cylinder lifts and lowers, thereby driving the film-spreading assembly 001 to achieve linear lifting and lowering motion. In this embodiment, the height of the film-spreading assembly 001 is adjusted by the lifting cylinder 004 according to the height of the film covering.

[0032] In this embodiment, the film-cutting assembly 001 includes a blade 011, a positioning pin 016, a connecting plate 015, and a slider 013. The connecting plate 015 is fixedly mounted on the slider 013 via the positioning pin 016. The blade 011 is vertically mounted on the slider 013 via the connecting plate 015. The blade 011 in this invention is a pentagonal blade with five independent cutting edges. When one cutting edge wears out, the blade 011 can be rotated to use the next cutting edge, extending the overall service life of the blade 011. The pentagonal blade 011 is connected to the connecting plate 015 via a gasket 012. The connecting plate 015 fixes the pentagonal blade and the slider 013, increasing the stability of the pentagonal blade during the film-cutting process.

[0033] The film-cutting assembly 001 also includes a locking component 014, which is fixedly connected to the slider 013. After the position distance of the film-cutting assembly 001 on the first track 002 is adjusted, the operator needs to manually fasten the locking component 014. The locking component 014 fixes and locks the slider 013 and the first track 002 to prevent the film-cutting assembly 001 from falling off or separating from the first track 002 during the film-cutting process.

[0034] The drive center includes a drive device, a second track 003, and a mounting frame 005. The drive center is connected to the mounting frame 005, and the second track 003 is fixed on the mounting frame 005. The drive device drives the load-bearing structure to move on the second track 003 via a slider 013.

[0035] In this utility model, the driving device includes a motor 008, a driving wheel 007, a synchronous belt 017, and a driven wheel 006. The motor 008 is mounted on a mounting frame 005, the driving wheel 007 is connected to the output end of the motor 008, the driven wheel 006 is mounted on the mounting frame 005, and the two ends of the synchronous belt 017 are respectively wrapped around the driving wheel 007 and the driven wheel 006. The motor 008 drives the driving wheel 007 to rotate, which in turn drives the driven wheel 006 to rotate through the synchronous belt 017. Since the synchronous belt 017 is connected to the support plate, it drives the load-bearing structure to move.

[0036] Below the second track 003, extending in the following directions, are sequentially arranged: a first detection switch 018, a second detection switch 019, and a third detection switch 020. When the supporting structure moves to the second detection switch 019, the sensing plate at the bottom of the support plate passes through the second detection switch 019, and the motor 008 changes its rotation direction or stops. The supporting structure moves along the second track 003 towards the third detection direction via the slider 013. When the sensing plate reaches the third detection switch 020, the above process is repeated. For the safety and stability of the equipment operation, if the second detection switch 019 malfunctions, when the supporting structure moves along the second track 003 to the first detection switch 018, the sensing plate reaches the first detection switch 018, the motor 008 immediately stops, and the supporting structure moves along the second track 003 towards the third detection switch 020.

[0037] By setting a detection switch and a sensor plate to control the rotation direction of the motor 008, the moving direction of the bearing structure on the second track 003 via the slider 013 is realized, thereby maintaining the stability of the equipment operation and increasing the film-cutting efficiency of the film-cutting assembly 001.

[0038] Meanwhile, the mounting bracket 005 is also equipped with a limiting block 009, which is set at both ends of the second track 003. The bottom of the support plate is equipped with a stop block 010, which is set in accordance with the limiting block 009. The stop block 010 moves between the two limiting blocks 009.

[0039] By setting two sets of limit blocks 009 to limit the movement of the stop block 010, the movement distance of the bearing structure within the preset range is achieved, thus maintaining the stability of the membrane cutting mechanism.

[0040] In specific operation: the lifting cylinder 004 drives the support plate to perform linear lifting and lowering movements to adjust the film-cutting component 001 to the optimal film-cutting height according to the film covering height. According to the size of the battery component, i.e. the required film-cutting size, the slider 013 is manually adjusted to move on the first track 002 to adjust the position of the film-cutting component 001. The locking piece 014 is then manually engaged.

[0041] Motor 008 drives the drive wheel 007 to rotate, which in turn drives the driven wheel 006 to rotate via synchronous belt 017. Synchronous belt 017 is connected to the support plate, thereby driving the load-bearing structure to move via slider 013 on the second track 003. When the load-bearing structure moves to the second detection switch 019 via the second track 003, the sensing plate at the bottom of the support plate reaches the second detection switch 019, and motor 008 changes its rotation direction. The load-bearing structure moves to the third detection switch 020 via the second track 003. When the load-bearing structure reaches the third detection switch 020 and the sensing plate reaches the third detection switch 020, the above process is repeated.

[0042] It is worth noting that when the second detection switch 019 malfunctions, the supporting structure moves to the first detection switch 018 via the second track 003. When the sensing element reaches the first detection switch 018, the motor 008 immediately stops working. The operator immediately stops the machine to inspect and replace the damaged second detection switch 019. Production can only resume after the replacement is completed.

[0043] In summary: by manually adjusting the moving distance of the film-cutting component 001 on the first track 002, and by making vertical linear movement with the second track 003 through the supporting structure, the separation of the film by the pentagonal blade is achieved, which solves the problem of fixed and single film-cutting size in the prior art; by driving the first track 002 to perform linear lifting and lowering motion through the lifting cylinder 004, the problem of fixed blade lifting and adjusting in traditional film-cutting equipment is solved.
