Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module recycling technology, specifically relating to a photovoltaic module frame strip cleaning process based on simultaneous straightening and cutting. Background Technology

[0002] Photovoltaic modules include glass panels, EVA adhesive layers, solar cells, backsheets, junction boxes, and frames. More than 90% of these materials can be recycled and reused. In particular, the frames are mainly dismantled by peeling. Once the edges are damaged, a large amount of adhesive and glass will remain in the mating grooves of the frame strips. Therefore, it is necessary to remove the residue in the mating grooves to achieve unadulterated and high-purity recycling of the frame strips.

[0003] Currently, during the peeling process, the frame strip is basically broken by the external support wheel. During the external support process, the frame strip is inevitably deformed, usually from both ends. Therefore, before cleaning the groove, it is necessary to straighten and position it, and then use a tool to cut and clean the groove.

[0004] However, the mating groove includes an insert groove that matches the laminate and an adhesive-receiving groove located at the opening of the insert groove and recessed from the groove wall. If the above-mentioned cleaning steps are used, the following technical problems exist: 1. The cleaning tank basically removes the residue in the inserting tank, but it cannot remove the glue tank. Therefore, there is a high residual glue rate. If the frame strip is recycled directly, it will not only affect the purity of the frame recycling, but also make it impossible to recycle it to the raw material standard. Moreover, the residual glue will generate gas in subsequent melting or pyrolysis, causing environmental pollution or increasing gas treatment costs. 2. The straightening and cutting of the edge strip are done separately, and the cutting is not done in one go. Therefore, the efficiency of cleaning the groove is low. At the same time, once the straightening is deviated, it will not only easily cause the scraper to break, but also increase the residual glue rate (caused by incomplete scraping). 3. During the grooving process, the frame strip moves upward from the groove opening of the mating groove. The scraper is positioned above the frame strip and performs multiple cuts according to the set cutting amount. However, it is impossible to guarantee that all the chips generated by the cutting will be discharged from the insert groove with the scraper. Once the chips cause scraping interference, not only is the scraping efficiency low, but it is also easier to form residual glue. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a novel process for cleaning grooves in the frame strips of photovoltaic modules based on the synchronization of straightening and cutting.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A photovoltaic module frame strip cleaning process based on simultaneous straightening and cutting, wherein the frame strip has frame grooves extending along its own length, wherein the frame grooves include insertion grooves and adhesive grooves, and the process includes the following steps: S1. Straightening The edge strip enters from the edge groove downwards and is straightened by multiple straightening wheels arranged vertically. Each straightening wheel constitutes a straightening point, and multiple straightening points form a straightening channel. The straightening channel generates a forward pushing force to straighten and transmit the edge strip from the receiving end to the discharge end. S2. Main Cleaver The main cutting tool extends from the bottom up into the straightening channel at the front end of the receiving end, and at least one straightening point is provided above the main cutting tool to match it. The straightened forward-moving edge strip moves relative to the main cutting tool to form the main cutting, so as to remove the rubber strip and glass in the insert groove, and the removed waste chips fall freely. S3. Enlarging the groove The front section of the main cutting tool is equipped with a grooving mold that can extend into the straightening channel, and the grooving mold has at least one straightening point above it to match it. After the main cutting is completed, the side wall where the glue-containing groove is located is expanded outward based on the wedge of the grooving mold to increase the downward groove opening of the glue-containing groove. S4. Auxiliary cutting The front section of the grooving mold is equipped with an auxiliary cutting tool that can extend into the straightening channel. After the grooving is completed, the edge strip is used to remove the adhesive strip and glass in the insert groove and the adhesive groove based on the auxiliary cutting tool. The removed waste chips fall freely or move with the machine. After the auxiliary cutting is completed, the material is discharged from the discharge end of the straightening channel.

[0007] According to a specific embodiment and preferred aspect of the present invention, in step S1, the frame groove faces downwards, the adhesive-containing groove is located on the lower left side of the mounting groove, and the straightening channel forms a first degree of freedom calibration based on multiple straightening points in the vertical direction and a second degree of freedom calibration based on multiple contact points on the left and right sides of the frame strip in the horizontal direction. The frame strip undergoes primary and secondary cutting sequentially under the cooperation of the first and second degree of freedom calibrations to remove residual adhesive and glass from the mounting groove and adhesive-containing groove. This not only achieves positional calibration in the vertical and horizontal directions but also ensures that the entire cutting action is completed under the same standard, thereby improving the efficiency and quality of the cleaning process.

[0008] Preferably, the first degree of freedom calibration is a fixed-mode calibration, and it is based on the bottom surfaces of multiple upper straight wheels and the top surfaces of multiple lower straight wheels, wherein the bottom and top surfaces are parallel and the vertical spacing is equal. The second degree of freedom calibration is a set-mode or follow-up matching mode calibration, and it is based on the contact point formed on the right side as a reference. According to the position change of the left side of the frame strip from the reference, the left contact point is set and / or the left contact point is dynamically matched to form the left and right direction degree of freedom calibration. Based on the mutual cooperation of different mode calibrations, not only are the position calibration requirements of the upper, lower, left, and right sides under the change of the frame strip contour met, but the deformation of the frame strip in the upper, lower, left, and right directions is not caused during the scraping and expansion process, so that the entire scraping and expansion are on the same reference plane, thereby achieving a clean groove without residue in the frame groove.

[0009] In some specific implementations, the second degree of freedom calibration is based on left and right limiting ring plates positioned on the left and right sides of the upper and / or lower straight wheels, respectively. The right limiting ring plate serves as a reference, and the left limiting ring plate is aligned according to the change in distance from the left side of the frame strip to the reference. The left limiting ring plate layout, using a rated position, satisfies the left and right straightening requirements after deformation.

[0010] Alternatively, the second degree of freedom calibration includes an elastic baffle that maintains an inwardly folded shape around the vertical axis. The elastic baffle maintains an inwardly resisting motion against the side of the frame strip, and adaptively expands outward based on the outward expansion of the left side of the frame strip. A limiting ring layout with a rated position is used to meet the left-right straightening requirements after deformation. Alternatively, a layout using elastic baffles is used, with the left and right alignment achieved through active contact; or a layout using a combination of limiting rings and elastic baffles is used to meet the left-right calibration requirements.

[0011] According to another specific embodiment and preferred aspect of the present invention, in step S2, the main cutting tool is a multi-edged tool, which includes a disc cutter, a toothed cutter, a roller cutter, and a face milling cutter. The cutting width of the multi-edged tool is less than or equal to the width of the insert groove. Simultaneously, the multi-edged tool rotates while cutting, and the cutting exerts a force on the frame strip opposite to the transmission direction. Generally, the cutting width is equal to the width of the insert groove. Thus, during the main cutting, most of the residue can be removed, and the removed chips are discharged out of the insert groove (downwards) with the cutting. Simultaneously, under the relative rotation of the cutting tool, not only is the grooving removal completed, but an auxiliary force in the vertical direction is also generated to assist in the relative alignment in the vertical direction.

[0012] Preferably, a straightening point is provided directly above the main cutting tool. Based on the straightening force provided above, deformation at the corresponding position is avoided due to the stress generated by cutting, thereby improving the straightening and grooving quality.

[0013] According to another specific embodiment and preferred aspect of the invention, in step S3, the grooving mold is wedged in based on the side of the insert groove away from the adhesive groove, and the side of the adhesive groove is turned outward by the grooving mold. Using one side as a reference, the bottom of the side is turned outward relative to each other by contact.

[0014] Preferably, in step S3, the grooving mold includes a frustum-shaped wedge with an outer contour. The bottom surface of the frustum is used as the reference surface, and the side of the moving frame strip is progressively expanded outwards towards the top surface of the frustum by the contact between the frustum surface and the frame strip. Based on the progressive contour contact formed by the conical surface, the raised side is kept at the same angle and with the same outward width. This not only facilitates left-right calibration but also allows for auxiliary cutting while maintaining the same posture, thereby improving the grooving quality and significantly reducing the residual rate of the frame groove.

[0015] According to another specific embodiment and preferred aspect of the present invention, the grooving mold further includes a scraping wedge located between the frustum wedge and the main cutting tool. The scraping wedge extends into the insert groove after the main cutting, and the scraping wedge includes a wedge body and a wedge cutting edge, wherein the wedge cutting edge removes the residue on the wall surface of the frame strip corresponding to the reference surface, and the wedge body matches and fits the groove wall of the insert groove. Based on the wedge cutting edge layout, unevenness of the reference surface caused by the main cutting (residue caused by improper switching) is avoided, thereby maintaining the same reference for side expansion; based on the wedge body layout, deformation of the insert groove caused by the main cutting is avoided, thereby maintaining the same posture for side expansion.

[0016] According to another specific embodiment and preferred aspect of the invention, in step S4, the auxiliary tool is a brush roller, wherein the brushing area formed by the brushing portion of the brush roller covers the entire frame groove. Based on the comprehensive brushing coverage, not only is the residual rate of the frame groove reduced, but the adhesive groove can also be completely removed.

[0017] In some specific embodiments, the brush roller is a steel wire brush roller (of course, the bristles can also be made of nylon or sisal), and the steel wire brush roller exerts a force on the edge strip in the same direction as the transmission direction. Here, the resulting brushing and shaving not only removes residue from the groove, but also assists in transmission and vertical straightening.

[0018] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art: 1. Based on the collaboration of main cutting, external expansion, and auxiliary cutting, the residual material in the insert groove and adhesive groove can be completely removed in one go through synchronous straightening assistance. This not only greatly improves the cleaning efficiency, but also ensures that the reference of the cutting and external expansion sections is the same, avoiding uneven cutting or omissions, and reducing the tool chipping rate and cleaning residue rate. 2. Based on the layout of the straightening points and the positions of the cutting and expansion, the straightening force and the grooving stress of the alignment are matched, which solves the problem of deformation of the frame strip during the grooving process. At the same time, the coupling design of the straightening points and the cutting path not only enhances the thoroughness of the grooving, but also provides a high-precision reference surface for subsequent assembly processes, realizing an integrated process breakthrough of grooving, straightening and shaping. In addition, the groove opening of the frame groove faces downward, and the cutting waste falls with the movement or freely, avoiding the interference of the cutting waste. 3. Under the cooperation of the first and second degrees of freedom calibration, the main and auxiliary cutting of the frame strip are carried out in sequence to remove residual glue and glass in the mounting groove and glue container groove. This not only achieves positional calibration in the up and down and left and right directions, but also ensures that the entire cutting action is completed under the same standard, thereby improving the cleaning efficiency and quality. 4. The first degree of freedom calibration is a fixed mode calibration, and the second degree of freedom calibration is a set mode or a follow-up matching mode calibration. The cooperation of different mode calibrations not only meets the position calibration requirements of the upper, lower, left and right sides under the change of the outline of the border strip, but also does not cause deformation of the border strip in the upper, lower, left and right directions during the scraping and expansion process, so that the entire scraping and expansion are on the same reference plane, thereby achieving a clean groove without residue in the border groove. 5. A limiting ring layout with a rated position is adopted to meet the left and right straightening requirements after deformation. Alternatively, an elastic baffle layout is adopted, which maintains fit based on movable resistance to achieve left and right calibration; or, a layout using both limiting rings and elastic baffles is adopted to meet the left and right calibration requirements. 6. The cutting width is equal to the width of the insert groove. This allows most of the residue to be removed during the main cutting, and the waste chips are discharged out of the insert groove (downward) with the cutting. Simultaneously, the relative rotation of the cutting tool not only completes the grooving but also generates an auxiliary force in the vertical direction to assist in relative alignment. A straightening point is also located directly above the main cutting tool. Based on the straightening force provided above, deformation at the corresponding position is avoided due to the stress generated during cutting, thereby improving the straightening and grooving quality. 7. Using one side as a reference, the bottom of the side is turned outward by contact. Specifically, the contact is based on the progressive contour formed by the conical surface, so that the raised side is kept at the same angle and the same outward width. This not only facilitates the calibration in the left and right directions, but also allows for auxiliary cutting while maintaining the same posture, thereby improving the quality of the groove and significantly reducing the residual rate of the frame groove. 8. Based on the wedge body layout, avoid unevenness of the reference caused by the main cutting (residual damage caused by improper switching), thus maintaining the same reference for side expansion; based on the wedge head body layout, avoid deformation of the insert groove caused by the main cutting, thus maintaining the same posture for side expansion. 9. Based on the full coverage of the brush roller, the brushing not only reduces the residual rate of the edge groove, but also completely removes the adhesive groove; 10. The brush roller is a steel wire brush roller (of course, the bristle material can also be nylon or sisal). At the same time, the steel wire brush roller exerts a force on the edge strip in the same direction as the transmission direction. Here, the brushing and shaving can not only remove the residue in the groove, but also assist in the transmission and vertical straightening. Attached Figure Description

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0026] like Figure 1and Figure 2 As shown, the frame strip t of this embodiment has a frame groove s extending along its own length direction, wherein the frame groove s includes an insert groove s1 and a glue groove s2, and the photovoltaic module frame strip cleaning device is used for the complete cleaning of the insert groove s1 and the glue groove s2.

[0027] Combination Figures 3 to 7 As shown, the photovoltaic module frame strip cleaning equipment includes a straightening unit 1 and a removal unit 2. The straightening unit 1 includes a first straightening component 11 that forms a first degree of freedom for vertical calibration and a second straightening component 12 that forms a second degree of freedom for horizontal calibration. The removal unit 2 includes a main removal component 20, an outer expansion component 21, and an auxiliary removal component 22.

[0028] In some specific embodiments, the first straightening component 11 includes upper straightening wheels 110 and lower straightening wheels 111 arranged vertically. The bottom surfaces of the multiple upper straightening wheels 110 are aligned, and the top surfaces of the multiple lower straightening wheels 111 are aligned. A straightening channel with equal spacing is formed between the upper straightening wheels 110 and the lower straightening wheels 111. At the same time, the first degree of freedom is calibrated in a fixed mode, with the bottom surface and top surface of the wheel being parallel and the vertical spacing being equal. The frame strip t is straightened and transmitted from the receiving end to the discharge end.

[0029] In this example, a guide module 112 is provided at the receiving end, which is aligned with the top surface of the lower straightening wheel 111. The frame strip t enters the straightening channel after facing downward from the frame groove s and fitting into the guide module 112.

[0030] In some specific implementations, the second degree of freedom calibration is a set mode or follow-up matching mode calibration, and the second degree of freedom calibration is based on the contact point formed on the right side as a reference, and according to the position change of the left side of the border strip t from the reference, the left contact point is set and / or the left contact point is matched to form the left and right direction degree of freedom calibration.

[0031] Specifically, the second straightening component 12 includes a left limiting ring 120 and a right limiting ring 121 arranged on the left and right sides of the upper straightening wheel 110 and the lower straightening wheel 111, and an elastic baffle 122 that maintains elastic inward rotation in the vertical direction. The left limiting ring 120 is aligned with the right limiting ring 121 as a reference, depending on the distance from the left side of the frame strip to the reference. The elastic baffle 122 maintains an inward contacting motion trend, elastically contacting the side of the frame strip t, and adaptively expands outward based on the outward expansion of the left side of the frame strip t. In short, the limiting ring arrangement with a fixed position satisfies the left and right straightening requirements after deformation. Alternatively, the elastic baffle arrangement maintains a close fit based on active contact to achieve left and right calibration; or, the limiting ring and the elastic baffle work together to satisfy the left and right calibration requirements. In this example, a combination of a limiting ring and an elastic baffle is used to create a variable left-side limit between the outward expansion and the main cutting, which further improves the limit calibration under the change, thereby improving the cleaning efficiency and quality.

[0032] Furthermore, the flexible baffle 122 can be positioned on the left or right side, generally on the right side, but can also be positioned on the left side when needed.

[0033] In some specific embodiments, the main cutting assembly 20 includes a multi-bladed tool 200 (main cutting tool) and a power unit 201. The multi-bladed tool 200 includes a disc cutter, a toothed cutter, a roller cutter, and a face milling cutter. The cutting width of the multi-bladed tool 200 is equal to the width of the insert groove. The multi-bladed tool 200 rotates while cutting, and the cutting exerts a force on the frame strip opposite to the transmission direction. In this example, a straightening point is provided directly above the multi-bladed tool 200. Based on the straightening force provided above, deformation at the corresponding position is avoided due to the stress generated by cutting, thereby improving the straightening and grooving quality. In this example, the power unit 201 uses a conventional motor and pulley drive.

[0034] The expansion component 21 includes a frustum wedge 210 with an outer contour in the shape of a frustum, and a scraping wedge 211 located between the frustum wedge 210 and the multi-blade tool 200. The bottom surface of the frustum surface is used as the reference surface. The side of the frame strip t is gradually expanded outward from the top surface of the frustum surface by the contact between the frustum surface and the moving frame strip t. The scraping wedge 211 includes a wedge body a and a wedge blade b. The wedge blade b removes the residue on the wall surface of the frame strip t corresponding to the reference surface. The wedge body a matches and fits the groove wall of the mounting groove s1.

[0035] The auxiliary cutting assembly 22 includes a brush roller 220 and a power device 221, wherein the brushing area formed by the brushing portion of the brush roller 220 covers the entire frame groove s. Based on the comprehensive brushing coverage, not only is the residue rate in the frame groove reduced, but the adhesive residue in the groove is also completely removed. The brush roller 220 is a steel wire brush roller (the bristles can also be made of nylon or sisal), and the steel wire brush roller exerts a force on the frame strip in the same direction as the transmission direction. This brushing auxiliary cutting not only removes residue from the groove but also assists in transmission and vertical straightening. Furthermore, the steel wire brush roller can further treat the metal surface, making it easier to recycle the frame strip. In this example, the power device 221 uses a conventional motor and pulley drive.

[0036] The photovoltaic module frame strip cleaning process in this embodiment includes the following steps: S1. Straightening The frame strip enters from the frame groove downwards and is straightened by multiple straightening wheels arranged vertically. Each straightening wheel constitutes a straightening point, and multiple straightening points constitute a straightening channel. The straightening channel generates a forward pushing force to straighten and transmit the frame strip from the receiving end to the discharge end. At the same time, the straightening channel forms a first degree of freedom calibration based on multiple straightening points in the vertical direction and a second degree of freedom calibration based on multiple contact points on the left and right sides of the frame strip in the left and right direction. S2. Main Cleaver A multi-bladed tool with part of the tool body extending from bottom to top into the straightening channel at the front end of the receiving end, and at least one straightening point matching it above the multi-bladed tool, the frame strip moves forward relative to the rotating multi-bladed tool under the cooperation of the first degree of freedom calibration and the second degree of freedom calibration to form the main cutting, so as to remove the rubber strip and glass in the insert groove, and the removed waste chips fall freely or move with it. S3. Enlarging the groove The front section of the main cutting tool is equipped with a grooving mold that can extend into the straightening channel. The grooving mold includes a frustum wedge with an outer contour of frustum and a scraping wedge located between the frustum wedge and the main cutting tool. The scraping wedge extends into the insert groove after the main cutting. The scraping wedge includes a wedge body and a wedge blade. The wedge blade removes the residue on the wall of the frame strip corresponding to the reference surface. The wedge body matches and fits the groove wall of the insert groove. The frame strip moves to the frustum wedge after passing through the scraping wedge. Based on the bottom surface of the frustum surface as the reference surface, the side of the frame strip gradually expands outward towards the top surface of the frustum surface by the contact between the frustum surface and the moving frame strip, so as to increase the downward groove opening of the adhesive groove. S4. Auxiliary cutting The front section of the grooving mold is equipped with a wire brush roller that can extend into the straightening channel and complete the grooving of the frame strip. With the cooperation of the first and second degrees of freedom calibration, the frame strip removes the glue strip and glass in the insert groove and the glue container groove by the covering brushing of the wire brush roller. The wire brush roller exerts a force on the frame strip in the same direction as the transmission direction, and at the same time removes the waste chips that move or fall freely. After the auxiliary cutting is completed, the material is discharged from the discharge end of the straightening channel.

[0037] In summary, the above-mentioned photovoltaic module frame strip cleaning process offers the following advantages: Firstly, based on the collaboration of main cutting, outward expansion, and auxiliary cutting, the simultaneous straightening assistance completes the thorough removal of residues from the insert groove and adhesive groove in one go. This not only significantly improves cleaning efficiency but also ensures that the cutting and outward expansion sections have the same reference, avoiding uneven cutting or omissions and reducing tool breakage rate and cleaning residue rate. Secondly, based on the layout of the straightening points and the positions of the cutting and outward expansion, the straightening force and the alignment cleaning stress are matched, solving the problem of frame strip deformation during the cleaning process. Simultaneously, the coupling between the straightening points and the cutting path... The integrated design not only enhances the thoroughness of the cleaning process but also provides a high-precision reference surface for subsequent assembly processes, achieving a breakthrough in the integrated process of cleaning, straightening, and shaping. Furthermore, with the groove opening facing downwards, the removed debris either moves with the machine or falls freely, preventing debris from interfering with the cutting process. Thirdly, the frame strip undergoes primary and secondary cutting sequentially under the coordination of the first and second degrees of freedom calibration to remove residual adhesive and glass from the mounting groove and adhesive groove. This not only achieves positional calibration in the vertical and horizontal directions but also ensures that the entire cutting action is completed under the same standard, thereby improving the cleaning efficiency. And quality; Fourthly, the first degree of freedom calibration is fixed mode calibration, and the second degree of freedom calibration is set mode or follow-up matching mode calibration. The mutual cooperation of different mode calibrations not only meets the position calibration requirements of the upper, lower, left and right sides under the change of the outline of the frame strip, but also does not cause deformation of the frame strip in the upper, lower, left and right directions during the scraping and expansion process, so that the entire scraping and expansion are on the same reference plane, thereby achieving a clean groove without residue in the frame groove; Fifthly, the limit ring plate layout with rated position layout is adopted to meet the left and right straightening requirements after deformation, or, an elastic stop is adopted. The plate layout is based on the active contact to maintain fit and form left and right alignment, or it adopts the layout of limiting ring plate and elastic baffle to meet the left and right alignment requirements, which is highly practical; the sixth aspect is that the cutting width is equal to the groove width of the insert, so that most of the residue can be removed during the main cutting, and the removed chips are discharged out of the insert groove (downward) with the cutting; at the same time, under the relative rotation cutting of the cutting tool, not only is the groove cleaning removed, but also an auxiliary force in the vertical direction can be formed to assist the relative alignment in the vertical direction. At the same time, a straightening point is set directly above the main cutting tool.Based on the straightening force provided directly above, deformation at the corresponding position is avoided due to the stress generated by cutting, thereby improving the straightening and grooving quality; seventhly, taking one side as a reference, the bottom of the side is turned outward by contact, specifically based on the progressive contour contact formed by the conical surface, so that the raised side is kept at the same angle and the same outward turning width, which not only facilitates the calibration in the left and right directions, but also allows auxiliary cutting to be carried out in the same posture, thereby improving the grooving quality and significantly reducing the residual rate of the frame groove; eighthly, based on the wedge-shaped body layout, the unevenness of the reference caused by the main cutting (residual groove caused by improper switching) is avoided. (remaining), thus maintaining the same benchmark for side expansion; based on the layout of the wedge head body, the deformation of the insert groove caused by the main cutting is avoided, thus maintaining the same posture for side expansion; the ninth aspect is based on the brushing and sweeping with full coverage of the brush roller, which not only reduces the residual rate of the edge groove, but also completely removes the adhesive groove. At the same time, the brush roller is a steel wire brush roller (of course, the bristle material can also be nylon or sisal), and the steel wire brush roller forms a force on the edge strip in the same direction as the transmission direction. Here, the brushing and sweeping auxiliary cutting can not only remove the residue in the groove, but also assist in transmission and vertical straightening.

[0038] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.
