Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaics, and in particular relates to a rubber strip scraping mechanism for recycling frame strips. Background Art

[0002] Photovoltaics is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of operation: independent operation and grid-connected operation. Photovoltaic panel components are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon), including glass plates, EVA adhesive layers, battery cells, backplanes, junction boxes and frames. More than 90% of the materials can be recycled and reused, with considerable recycling value and high economic profits. Therefore, photovoltaic components that have reached the end of their life need to be recycled, which not only alleviates the shortage of raw materials for photovoltaic devices to a certain extent, but also avoids pollution to the environment.

[0003] At present, for the recycling of photovoltaic modules, the existing technology generally first removes the frame and junction box in the photovoltaic module, and then separates the glass and battery cells; finally, the peeled battery cells are further recycled.

[0004] However, in the actual production process, after the frame is peeled off, the groove formed by the frame is prone to residual glue strips and broken glass adhered to the glue strips, which is not convenient for direct recycling and utilization of the frame. Therefore, after the frame is removed, the glue strips and broken glass need to be scraped off. However, when using a conventional glue scraper to scrape off the glue strips, since the frame groove is overall narrow and long and easy to deform, as the glue scraper moves, the glue strips are difficult to discharge smoothly and are prone to accumulation, blockage or secondary falling into the frame groove, thereby greatly hindering the movement of the glue scraper (forward movement to scrape glue or reverse movement to reset), which not only leads to low scraping efficiency and poor scraping effect, but also causes a high damage rate and high cost of the glue scraper. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved rubber strip scraping mechanism for recycling border strips.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0007] A rubber strip scraping mechanism for recycling border strips, the border strip having a border groove extending forward and backward, the scraping mechanism comprising a movable die base which reciprocates along the forward and backward directions, a scraping blade module arranged on the movable die base, and a pressing module, the scraping blade module comprising a front scraping blade head and a back scraping blade head arranged front and back, wherein the front scraping blade head comprises a multi-stage front scraping blade which is inclined forward and scrapes in layers from front to back, the sum of the scraping amounts formed by the multi-stage front scraping blades is equal to the groove depth of the border groove, and a chip removal space is formed at the front end of each stage of the front scraping blades; the back scraping blade head comprises a back scraping blade which is inclined backward and has a chip removal space formed at the rear end; the rubber strip scraping mechanism also comprises a forward pushing module located at the front end of the movable die base, wherein the forward pushing module is pressed on the border strip and flattens the scraping segments segment by segment as the movable die base moves synchronously.

[0008] According to a specific implementation and preferred aspect of the present invention, the scraping amount formed by each two adjacent front scrapers is equal; or / and, the scraping amount formed by the multiple front scrapers increases step by step from front to back. Here, according to the actual distribution of the rubber strip and the broken glass, the scraping amount of each front scraper is controlled to improve the scraping effect under layered scraping, reduce scraper wear, and extend service life.

[0009] Preferably, the left and right sides of the front scraper head are separated from the corresponding side walls of the frame groove and form a gap connected to each chip removal space. When scraping forward, the rubber strip debris entering the chip removal space is discharged from the frame groove through the gap under the extrusion force. Here, not only can the rubber strip debris and broken glass be pushed forward out of the front end of the frame groove, but also the chips can be removed while scraping forward, so as to reduce the resistance caused by the accumulation of rubber strip debris and broken glass.

[0010] Specifically, the front scraper head is divided into a plurality of segments arranged sequentially from front to rear, wherein the width of the plurality of segments in the left-right direction gradually increases from front to rear, and the front scrapers of each level are sequentially distributed on each segment or / and at the junction of adjacent segments, thereby reducing the probability of waste chips falling into the rear in the front scraper.

[0011] According to another specific implementation and preferred aspect of the present invention, the multi-level front scraper blades are defined as the 1st, 2nd, 3rd, ... Mth level front scraper blades from front to back, wherein the front end face and the rear end face of the 1st level front scraper blade are both extended from top to bottom and tilted forward, and the bottom face is extended from the bottom edge of the front end face to the rear and then horizontally extended backward; the front end face and the rear end face of the 2nd to the Mth level front scraper blades are both extended from top to bottom and tilted forward, and the bottom face is extended from the bottom edge of the front end face to the rear and horizontally extended. The angle between the front end face and the bottom face of the 1st level front scraper blade is smaller than the angle between the front end face and the bottom face of the 2nd to the Mth level front scraper blades, so that the rubber strip can be effectively broken by the 1st level front scraper blade to reduce the scraping difficulty of the 2nd to the Mth level front scraper blades.

[0012] According to another specific implementation and preferred aspect of the present invention, the scraper module also includes an auxiliary front scraper head arranged in front of the front scraper head, wherein the auxiliary front scraper head has a multi-stage auxiliary front scraper that is inclined forward and scrapes in layers from front to back, the sum of the scraping amount formed by the multi-stage auxiliary front scraper is less than or equal to the scraping amount formed by the first-stage front scraper, and an auxiliary chip removal space is formed at the front end of each stage of the auxiliary front scraper. Here, the multi-stage auxiliary front scraper further layers the scraping layer corresponding to the first-stage front scraper to achieve more refined scraping, which is very beneficial to the removal of broken glass on the surface of the rubber strip, thereby effectively reducing the difficulty of scraping and improving the scraping effect.

[0013] Preferably, the multi-level auxiliary front scraper blades are defined as the 1st, 2nd, 3rd, ... Nth level auxiliary front scraper blades from front to back, wherein the front end face and the rear end face of the 1st level auxiliary front scraper blade are both inclined and extended forward from top to bottom, and the bottom face is inclined and extended backward and horizontally from the bottom edge of the front end face; the front end face and the rear end face of the 2nd level auxiliary front scraper blade to the Nth level auxiliary front scraper blade are both inclined and extended forward from top to bottom, and the bottom face is horizontally extended backward from the bottom edge of the front end face, wherein the angle between the front end face and the bottom face of the 1st level auxiliary front scraper blade is smaller than the angle between the front end face and the bottom face of the 2nd to Nth level auxiliary front scraper blades, and the rear end face of the 2nd to N-1th level auxiliary front scraper blades is divided into an upper inclined surface and a lower inclined surface, and the inclination angle of the upper inclined surface is greater than the inclination angle of the lower inclined surface. Here, the layout of the upper and lower inclined surfaces is adopted, so that the auxiliary chip removal space formed is trumpet-shaped from top to bottom, which is convenient for large particles of waste chips such as broken glass scraped off to enter the auxiliary chip removal space.

[0014] Preferably, the difference in the amount of scraping formed by each two adjacent levels of auxiliary front scrapers is equal to the difference in the amount of scraping formed by each two adjacent levels of front scrapers; and / or, the angle between the front end face and the bottom face of the second to Nth level auxiliary front scrapers is 1.1 to 1.3 times the angle between the front end face and the bottom face of the second to Mth level front scrapers. Further preferably, the angle between the front end face and the bottom face of the second to Nth level auxiliary front scrapers is 70° to 80°; the angle between the front end face and the bottom face of the second to Mth level front scrapers is 55° to 65°.

[0015] According to another specific implementation and preferred aspect of the present invention, the back-shovel blade is arranged to fit the inner wall of the frame groove from the left and right side surfaces and the bottom surface, and the rear end surface of the back-shovel blade is formed with a first section extending obliquely from the bottom surface to the front and upward, and a second section connected to the upper end of the first section and forming an arc surface that arches upward. In this process, the waste chips can achieve a process of repeatedly moving upward and falling back under the squeezing force, and finally all discharged from the rear end of the frame groove, so that the waste chips can be effectively prevented from falling back into the frame groove for a second time.

[0016] Preferably, the back shovel blade head also includes an auxiliary back shovel blade that tilts forward and fits with the bottom of the frame groove from the bottom surface, wherein the back shovel blade and the auxiliary back shovel blade intersect from the upper end, and in the orthographic projection in the left and right directions, an isosceles triangle is formed between the front end surface of the back shovel blade, the rear end surface of the auxiliary back shovel blade, and the bottom surface of the frame groove. Here, the auxiliary back shovel blade is used to improve the support of the back shovel blade, reduce deformation, and extend the service life of the back shovel blade.

[0017] According to another specific implementation and preferred aspect of the present invention, the front push module is provided with a frame strip protruding upward, and as the front push module flattens the scraping section section by section, the front push module simultaneously cross-cuts the broken glass and the rubber strip protruding from the frame groove. Here, the rubber strip in the frame groove is scraped away while the broken glass and the rubber strip protruding from the frame groove are cut away.

[0018] Preferably, the forward pushing mold assembly comprises a forward pushing module fixedly connected to the movable mold base, wherein the height of the forward pushing module is 1.5 to 2 times the depth of the frame groove.

[0019] Preferably, the flattening length of the forward push module is 1 to 1.2 times the length of the scraping section. Here, it is ensured that the scraping section is in a flattened state and the resistance generated between the forward push module and the frame strip is prevented from being too high.

[0020] According to another specific implementation and preferred aspect of the present invention, the clamping module includes a supporting platform, a positioning grid arranged on the supporting platform and extending front to back, and a plurality of clamping components arranged above the supporting platform and spaced apart front to back, wherein a border strip is placed flat on the supporting platform and abuts against the positioning grid from one side, and the plurality of clamping components synchronously clamp the border strip from top to bottom.

[0021] In addition, each clamping assembly includes a vertically extending guide rail, a lifting plate connected to the guide rail for sliding up and down, a plurality of pressing plates connected to the bottom of the lifting plate and spaced apart from each other, and a driving member for driving the lifting plate to move up and down. Under this layout, the frame strips can be clamped in sections, so that workers can flexibly adjust the positions of different sections of the frame strips.

[0022] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0023] The grooves formed by the frames of the prior art are prone to residual adhesive strips and broken glass attached to the adhesive strips, which is not convenient for direct recycling and utilization of the frames. Therefore, after the frames are removed, the adhesive strips and broken glass need to be scraped off. However, when using a conventional adhesive scraper to scrape off the adhesive strips, since the frame grooves are narrow and long as a whole and are easily deformed, as the adhesive scraper moves, the adhesive strips are difficult to be discharged smoothly and are easily accumulated, blocked, or fall into the frame grooves for a second time, thereby greatly hindering the movement of the adhesive scraper (forward movement to scrape adhesive or reverse movement to reset), resulting in low adhesive scraping efficiency and poor adhesive scraping effect, and causing a high damage rate and high cost of the adhesive scraper. The present application provides a structure of an adhesive strip scraping mechanism for recycling frame strips. The overall design is carried out to cleverly solve the shortcomings and defects of the existing technology. After adopting the rubber strip scraping mechanism, after the frame strip is pressed by the pressing module, the front scraper head is driven to move forward by the moving mold base, so that the multi-stage front scraper forms layered scraping from front to back, wherein the sum of the scraping amounts formed by the multi-stage front scrapers is equal to the groove depth of the frame groove to gradually scrape off the rubber strip and broken glass in the frame groove, while keeping the forward push module pressed on the frame strip and flattening the scraping sections section by section with the synchronous movement of the moving mold base; then the moving mold base is moved backward by the moving mold base to drive the back scraper head to move back, so that the back scraper can scrape off all the remaining rubber strips and broken glass in the frame groove from the frame groove in one back scraping. Therefore, compared with the prior art, the present invention, on the one hand, is based on the layout of a multi-stage front scraper and a back scraper, and realizes the layer-by-layer removal of the rubber strips in the border groove through the front scraper and back scraper movement and the step-by-step flattening of the front push module, thereby effectively improving the removal rate of the rubber strips in the border strips; on the other hand, it effectively reduces the obstruction of the rubber strip waste to the tool in the border groove, greatly improves the scraping efficiency, extends the service life of the tool, and reduces costs.

[0044] like Figures 1 to 9 As shown, the rubber strip scraping mechanism for recycling the border strip involved in this embodiment includes a pressing module 1, a movable mold base 2, a scraper module 3, and a forward pushing module 4; the border strip T designed in this embodiment has a border groove T0 extending forward and backward and penetrating.

[0045] Specifically, the clamping module 1 includes a support platform 10, a positioning grid 11 arranged on the support platform 10 and extending forward and backward, and a plurality of clamping components 12 arranged above the support platform 10 and spaced apart from each other forward and backward, wherein the frame strip T is placed flat on the support platform 10 and abuts against the positioning grid 11 from one side, and the frame strip T keeps the opening of the frame groove T0 facing upward, and the plurality of clamping components 12 synchronously press the frame strip T from top to bottom and avoid the frame groove T0.

[0046] Each clamping assembly 12 includes a vertically extending guide rail 120, a lifting plate 121 connected to the guide rail 120 in an upward and downward sliding manner, a plurality of pressing plates 122 connected to the bottom of the lifting plate 121 and spaced apart from each other, and a driving member 123 for driving the lifting plate 121 to move upward and downward, wherein each pressing plate 122 is vertically arranged and pressed against the frame strip T from the bottom edge; the driving member 123 is a conventional telescopic cylinder. Under this layout, the frame strip can be clamped in sections, so that workers can flexibly adjust the positions of different sections of the frame strip.

[0047] In this example, the movable mold base 2 is arranged to reciprocate along the front-to-back direction, wherein an opening extending front-to-back is arranged on the support platform 10, and an annular transmission belt is arranged in the opening. The movable mold base 2 realizes the front-to-back reciprocating motion through the drive of the annular transmission belt d.

[0048] In this example, the scraper module 3 is arranged on the movable mold base 2, and includes a front scraper head 30 and a return scraper head 31 arranged front and rear, wherein the front scraper head 30 has a multi-stage front scraper 300 that is inclined forward and scrapes in layers from front to back, the sum of the scraping amounts formed by the multi-stage front scraper 300 is equal to the groove depth of the frame groove T0, and a chip removal space q0 is formed at the front end of each stage of the front scraper 300; the return scraper head 31 has a return scraper 310 that is inclined backward and has a chip removal space q0 formed at the rear end.

[0049] In some specific embodiments, the scraping amount formed by the multi-stage front scraper 300 increases step by step from front to back, and the difference in the scraping amount formed by each adjacent two-stage front scraper 300 is equal; the left and right sides of the front scraper head 30 are separated from the corresponding side walls of the frame groove T0 and form a gap x connected to each chip removal space q0. When scraping forward, the rubber strip debris entering the chip removal space q0 is discharged from the frame groove T0 through the gap x under the extrusion force; the front scraper head 30 is divided into a plurality of segments arranged sequentially from front to back, wherein the width of the plurality of segments in the left and right directions gradually increases from front to back, and the front scrapers 300 of each stage are sequentially distributed on each segment or / and at the junction of adjacent segments. Not only can the rubber strip debris and broken glass be pushed forward out of the front end of the frame groove, but also the chips can be removed while scraping during the process of scraping forward to reduce the resistance caused by the accumulation of rubber strip debris and broken glass.

[0050] The multi-level front scraper 300 is defined as the 1st, 2nd, 3rd, ... Mth level front scraper from front to back, wherein the front end face and the rear end face of the 1st level front scraper are both extended from top to bottom and tilted forward, and the bottom face is extended from the bottom edge of the front end face to the rear and then horizontally extended backward; the front end face and the rear end face of the 2nd to the Mth level front scraper are both extended from top to bottom and tilted forward, and the bottom face is extended from the bottom edge of the front end face to the rear and horizontally extended. The angle between the front end face and the bottom face of the 1st level front scraper is smaller than the angle between the front end face and the bottom face of the 2nd to the Mth level front scraper, so that the rubber strip can be effectively broken by the 1st level front scraper to reduce the scraping difficulty of the 2nd to the Mth level front scraper. In this embodiment, M=5.

[0051] For the convenience of implementation, the scraper module 3 also includes an auxiliary front scraper head 32 arranged in front of the front scraper head 30, wherein the auxiliary front scraper head 32 has a multi-stage auxiliary front scraper 320 that is inclined forward and scrapes in layers from front to back, the sum of the scraping amount formed by the multi-stage auxiliary front scraper 320 is less than or equal to the scraping amount formed by the first-stage front scraper, and an auxiliary chip removal space q1 is formed at the front end of each stage of the auxiliary front scraper 320. The multi-stage auxiliary front scraper further layers the scraping layer corresponding to the first-stage front scraper to achieve more refined scraping, which is very beneficial to the removal of broken glass on the surface of the rubber strip, thereby effectively reducing the difficulty of scraping and improving the scraping effect.

[0052] In some specific embodiments, the multi-level auxiliary front scraper 320 is defined as the 1st, 2nd, 3rd, ... Nth auxiliary front scraper from front to back, wherein the front end face and the rear end face of the 1st auxiliary front scraper are both extended from top to bottom and tilted forward, and the bottom face is extended from the bottom edge of the front end face to the rear and then horizontally extended backward; the front end face and the rear end face of the 2nd to the Nth auxiliary front scraper are both extended from top to bottom and tilted forward, and the bottom face is extended from the bottom edge of the front end face to the rear horizontally, wherein the angle between the front end face and the bottom face of the 1st auxiliary front scraper is smaller than the angle between the front end face and the bottom face of the 2nd to Nth auxiliary front scraper, and the rear end face of the 2nd to N-1th auxiliary front scraper is divided into an upper inclined surface and a lower inclined surface, and the inclination angle of the upper inclined surface is greater than the inclination angle of the lower inclined surface. Here, the layout of the upper and lower inclined surfaces is adopted, so that the auxiliary chip removal space formed is trumpet-shaped from top to bottom, which is convenient for large particles of waste chips such as broken glass scraped off to enter the auxiliary chip removal space. In this embodiment, N=5.

[0053] At the same time, the difference in the amount of scraping formed by each two adjacent levels of auxiliary front scrapers 320 is equal to the difference in the amount of scraping formed by each two adjacent levels of front scrapers 300; the angle between the front end face and the bottom face of the second to N levels of auxiliary front scrapers is 1.1 to 1.3 times the angle between the front end face and the bottom face of the second to M levels of front scrapers. Further preferably, the angle between the front end face and the bottom face of the second to N levels of auxiliary front scrapers is 70° to 80°; the angle between the front end face and the bottom face of the second to M levels of front scrapers is 55° to 65°. In this embodiment, the angle between the front end face and the bottom face of the first level of auxiliary front scrapers is 50°, and the angle between the front end face and the bottom face of the second to N levels of auxiliary front scrapers is 75°; the angle between the front end face and the bottom face of the first level of front scrapers is 45°, and the angle between the front end face and the bottom face of the second to M levels of front scrapers is 60°.

[0054] In this example, the front scraper head 30 and the back scraper head 31 are integrally formed, and the back scraper 310 is arranged to fit the inner wall of the frame groove T0 from the left and right sides and the bottom surface, and the rear end surface of the back scraper 310 is formed with a first section m1 extending obliquely from the bottom surface to the front and upward, and a second section m2 connected to the upper end of the first section m1 and forming an arc surface that arches upward. In the back scraping process, the waste can achieve a process of repeatedly moving upward and falling back under the extrusion force, and finally all discharged from the rear end of the frame groove, so that the waste can be effectively prevented from falling back into the frame groove for a second time.

[0055] For further convenience of implementation, the back-shovel blade head 31 also includes an auxiliary back-shovel blade 311 that is tilted forward and fits with the bottom of the frame groove T0 from the bottom surface, wherein the back-shovel blade 310 and the auxiliary back-shovel blade 311 intersect from the upper end, and in the orthographic projection in the left and right directions, an isosceles triangle is formed between the front end surface of the back-shovel blade 310, the rear end surface of the auxiliary back-shovel blade 311, and the bottom surface of the frame groove T0. Here, the auxiliary back-shovel blade is used to improve the support of the back-shovel blade, reduce deformation, and extend the service life of the back-shovel blade.

[0056] In addition, the forward push module 4 of this embodiment is located at the front end of the movable mold base 1, wherein the forward push module 4 is pressed on the side of the frame strip T away from the positioning grid 11 and flattens the scraping section section by section as the movable mold base 1 moves synchronously; the forward push module 4 is arranged to protrude upward from the frame strip T, and as the forward push module 4 flattens the scraping section section by section, the forward push module 4 synchronously cross-cuts the broken glass and rubber strip protruding from the frame groove T0. Here, the rubber strip in the frame groove is scraped away while the broken glass and rubber strip protruding from the frame groove are cut off.

[0057] In some specific embodiments, the forward push module 4 includes a forward push module 40 fixedly connected to the movable mold base 1, wherein the height of the forward push module 40 is 1.5 to 2 times the depth of the frame groove T0, and the flattening length of the forward push module 40 is 1 to 1.2 times the length of the scraping section. Preferably, the height of the forward push module 40 is 1.7 times the depth of the frame groove T0, and the flattening length of the forward push module 40 is 1 times the length of the scraping section. Here, it is ensured that the scraping section is in a flattened state, and it is also possible to avoid excessive resistance between the forward push module and the frame strip.

[0058] In summary, after adopting the rubber strip scraping mechanism, after the frame strip is pressed by the pressing module, the moving mold base moves forward to drive the front scraper head to move forward, so that the multi-stage front scrapers form layered scraping from front to back, wherein the sum of the scraping amounts formed by the multi-stage front scrapers is equal to the groove depth of the frame groove to gradually scrape away the rubber strips and broken glass in the frame groove, while keeping the forward push module pressed on the frame strip and flattening the scraping sections section by section with the synchronous movement of the moving mold base; then the moving mold base moves backward to drive the back scraper head to move back, so that the back scraper can scrape away all the remaining rubber strips and broken glass in the frame groove in one back scraping. Therefore, compared with the prior art, the present invention, on the one hand, is based on the layout of multi-stage front scrapers and back scrapers, and realizes layer-by-layer scraping of the rubber strips in the frame groove through the front scraping and back scraping movements and the step-by-step flattening of the front push module, thereby effectively improving the scraping rate of the rubber strips in the frame strips; on the other hand, it effectively reduces the obstruction of the rubber strip waste chips to the tool in the frame groove, greatly improves the scraping efficiency, extends the service life of the tool, and reduces the cost; thirdly, according to the actual distribution of the rubber strips and broken glass, the scraping amount of the front scrapers at each level is controlled to improve the scraping effect under layered scraping, reduce the wear of the scraper, and extend the service life; fourthly, it can not only push the rubber strip debris and broken glass forward out of the front end of the frame groove, but also realize scraping and chip removal during the front scraping process to reduce the resistance caused by the accumulation of rubber strip debris and broken glass; fifthly, the multi-stage auxiliary front scrapers further layer the scraping layer corresponding to the first-stage front scraper to achieve more refined scraping , which is very beneficial to the removal of broken glass on the surface of the rubber strip, thereby effectively reducing the difficulty of scraping and improving the scraping effect; on the sixth aspect, the layout of upper and lower inclined surfaces is adopted, so that the auxiliary chip removal space formed is trumpet-shaped from top to bottom, which is convenient for large particles of waste such as broken glass scraped off to enter the auxiliary chip removal space; on the seventh aspect, the return scraper of the present application is adopted. During the return scraping process, the waste chips can realize the process of repeated upward movement and falling back under the extrusion force, and finally all be discharged from the rear end of the frame groove, so that the waste chips can be effectively prevented from falling back into the frame groove for the second time; on the eighth aspect, the support of the return scraper is improved by the auxiliary return scraper, deformation is reduced, and the service life of the return scraper is extended; on the ninth aspect, the rubber strip in the frame groove is scraped away while the broken glass and rubber strip emerging from the frame groove are cut off; on the tenth aspect, multi-stage pressing is adopted. Under this layout, the frame strip can be pressed in sections, so that workers can flexibly adjust the positions of different sections of the frame strip.
