[0002] In the field of photovoltaic module manufacturing, photovoltaic frames serve to support, protect, and connect photovoltaic modules. With the increasing application of composite material photovoltaic frame profiles, the production and processing of these profiles typically requires drilling, cutting, and assembly processes to meet subsequent installation and usage requirements, as illustrated in patent application CN113411046A. For some photovoltaic frame profiles that have undergone drilling, to ensure the usability of the holes and their assemblability (e.g., connection with corner brackets), adhesive (e.g., resin) injection treatment is also required at the holes.

[0033] In one or more embodiments of this disclosure, the opening unit 20 may include an opening execution mechanism and a bearing support mechanism. The opening execution mechanism is used to open holes in the photovoltaic frame profile, and the bearing support mechanism is used to support a portion of the photovoltaic frame profile. When the opening execution mechanism performs the opening action, multiple through holes can be formed on the side wall of the photovoltaic frame profile. The structure of multiple through holes on the side wall of the photovoltaic frame profile can be found in the prior art, and will not be described in detail in this disclosure.

[0034] In one or more embodiments of this disclosure, preferably, the hole-opening mechanism includes a punching mechanism to form through holes in the sidewall of the photovoltaic frame profile by means of a stamping feed. Of course, in other embodiments, if theoretically or practically feasible, the hole-opening mechanism may also be a drilling mechanism. Accordingly, the hole-opening mechanism may include a drive mechanism and a drill bit. The drive mechanism may include a rotary drive mechanism and a feed drive mechanism. The drill bit performs drilling processing on the sidewall of the photovoltaic frame profile. This disclosure does not limit this aspect.

[0035] In one or more embodiments of this disclosure, a photovoltaic frame profile has a first end and a second end disposed opposite to each other. The first end has a 45-degree chamfered surface, and the second end has a 45-degree chamfered surface. Multiple opening units 20 are provided, including a first opening unit 21 and a second opening unit 22. The first opening unit 21 can be located at the first end, and the second opening unit 22 can be located at the second end. The first end can be understood as a position close to the first end, and the second end as a position close to the second end. The first opening unit 21 is used to open a hole in the sidewall portion of the photovoltaic frame profile at the first end, and the second opening unit 22 is used to open a hole in the sidewall portion of the photovoltaic frame profile at the second end. By respectively providing the first opening unit 21 and the second opening unit 22, holes can be opened in the sidewall portions at both ends of the photovoltaic frame profile. The first opening unit 21 and the second opening unit 22 can adopt the same structure, or different structures can be adopted according to the installation space and process requirements at both ends. This disclosure does not limit this.

[0036] In one or more embodiments of this disclosure, the dispensing unit 30 is used to dispense adhesive onto a photovoltaic frame profile having multiple through holes, such that the adhesive at least partially covers at least a portion of the multiple through holes. By dispensing adhesive onto some or all of the through holes, the adhesive can at least partially cover the through holes, thereby achieving partial or complete coverage, partial or complete sealing, or partial or complete filling of the through holes, thereby improving the sealing performance and usability of the photovoltaic frame profile at the corresponding location.

[0037] In one or more embodiments of this disclosure, the dispensing unit 30 may include a dispensing actuator and a moving mechanism. The dispensing actuator is used to apply adhesive into the through hole, and the moving mechanism is used to drive the dispensing actuator to move one by one to the corresponding position of the multiple through holes. Through the cooperation of the dispensing actuator and the moving mechanism, the adhesive can be output to the through hole.

[0038] In one or more embodiments of this disclosure, the dispensing actuator may include a glue storage container, a glue delivery line, a metering structure, and at least one of a dispensing nozzle, a glue injection nozzle, or a glue spray nozzle. Preferably, a dispensing nozzle is used, and the glue outlet end of the dispensing nozzle is arranged facing the through hole to facilitate the application of glue to the through hole. The metering structure is used to control the glue output to avoid problems such as excessive glue leading to overflow or insufficient glue leading to inadequate coverage. The metering structure may be one or more of a metering pump, a valve-controlled structure, or a pressure control structure, and this disclosure does not limit it.

[0039] In one or more embodiments of this disclosure, the dispensing unit 30 may optionally include an alignment structure for aligning the dispensing actuator with the through-hole. The alignment structure can employ visual recognition or sensor detection for alignment. By providing an alignment structure, it is beneficial to maintain the accuracy of the dispensing position and reduce adhesive misalignment.

[0040] In one or more embodiments of this disclosure, multiple dispensing units 30 are provided, including a first dispensing unit 31 and a second dispensing unit 32. The first dispensing unit 31 can be located at a first end, and the second dispensing unit 32 can be located at a second end. The first dispensing unit 31 is used to dispense adhesive into the through-hole formed at the first end, and the second dispensing unit 32 is used to dispense adhesive into the through-hole formed at the second end. Thus, by separately providing the first dispensing unit 31 and the second dispensing unit 32, adhesive can be dispensed into the through-hole positions at both ends of the photovoltaic frame profile, thereby reducing the large-scale movement of a single dispensing mechanism and improving dispensing efficiency. The first dispensing unit 31 and the second dispensing unit 32 can operate synchronously or sequentially, and this disclosure does not limit this.

[0041] In one or more embodiments of this disclosure, the first dispensing unit 31 and the first opening unit 21 are arranged at intervals and correspondingly, and the second dispensing unit 32 and the second opening unit 22 are arranged at intervals and correspondingly, so as to form corresponding pre-opening-post-dispensing processing stations at both ends of the photovoltaic frame profile.

[0042] In one or more embodiments of this disclosure, firstly, the photovoltaic frame profile to be processed is placed on the opening unit 20. The opening unit 20 carries, supports, and positions the photovoltaic frame profile, placing it in a predetermined processing posture. Subsequently, the opening unit 20 performs opening processing on the photovoltaic frame profile to form multiple through holes in the sidewall of the photovoltaic frame profile. Exemplarily, a first opening unit 21 and a second opening unit 22 can be provided. When the photovoltaic frame profile has a first end and a second end that are arranged opposite to each other, the first opening unit 21 opens a hole at the first end, and the second opening unit 22 opens a hole at the second end, thereby forming multiple through holes at both ends of the photovoltaic frame profile to form a photovoltaic frame profile with multiple through holes. The first opening unit 21 and the second opening unit 22 can simultaneously open the photovoltaic frame profile.

[0043] After the holes are drilled, the dispensing unit 30 dispenses adhesive onto the photovoltaic frame profile with multiple through holes. The dispensing actuator, under the action of the moving mechanism and / or the alignment structure, moves to the corresponding through hole position and applies adhesive to the through hole so that the adhesive at least partially covers the through hole, thereby completing partial or complete dispensing of adhesive into the multiple through holes. Exemplarily, a first dispensing unit 31 and a second dispensing unit 32 can be provided. The first dispensing unit 31 is used to dispense adhesive into some or all of the multiple through holes at the first end, and the second dispensing unit 32 is used to dispense adhesive into some or all of the multiple through holes at the second end. The first dispensing unit 31 and the second dispensing unit 32 can simultaneously dispense adhesive into the photovoltaic frame profile with multiple through holes, or they can dispense adhesive sequentially according to a predetermined order.

[0044] After dispensing, the adhesive remains at the through-hole location, partially or completely covering, partially or completely sealing, or partially or completely filling the through-hole. The adhesive can cure naturally or be cured under ultraviolet light, forming a relatively stable sealing or filling layer at the through-hole location. This completes the opening and dispensing process for the photovoltaic frame profile.

[0045] In one or more embodiments of this disclosure, preferably, the through-hole can be a tapered hole, allowing the colloid to flow and extend into the through-hole, partially or completely covering the interior of the through-hole after curing, thereby forming a partial or complete coverage, or partial or complete filling, of the through-hole. Because the tapered hole has a structural feature of varying pore size along the thickness direction, it is beneficial for achieving adhesion stability and retention of the colloid within the through-hole.

[0046] In this disclosure, by setting up a frame 10, an opening unit 20, and a dispensing unit 30, preferably, the first opening unit 21 and the second opening unit 22 can respectively open holes at the first end and the second end of the photovoltaic frame profile, the conveying mechanism can convey the photovoltaic frame profile with multiple through holes, and then the first dispensing unit 31 and the second dispensing unit 32 can respectively dispense glue at the first end and the second end, so that the opening process and the dispensing process of the photovoltaic frame profile can be completed on the same device, reducing the transfer links between processes, improving production efficiency and equipment integration, and the glue at least partially covers the through holes, which is beneficial to maintaining the sealing and structural strength of the opening part of the photovoltaic frame profile, and is suitable for the opening and dispensing processing of composite photovoltaic frame profiles.

[0047] In one aspect of the embodiments of this disclosure, the opening unit 20 includes a first bearing component, a first abutting support component, and an opening component. The first bearing component, the first abutting support component, and the opening component are all connected to a frame. The first bearing component supports and clamps the photovoltaic frame profile. The first abutting support component is partially inserted into the inner cavity of the photovoltaic frame profile and supports a portion of the side wall of the photovoltaic frame profile. The opening component makes an opening in the side wall of the photovoltaic frame profile.

[0048] In one or more embodiments of this disclosure, the first bearing component 301 and the first abutting support component can jointly constitute a bearing support mechanism, and the opening component can serve as an opening execution mechanism. The first bearing component can be used to support and clamp the outer side of the photovoltaic frame profile, thereby limiting the position of the photovoltaic frame profile and preventing the photovoltaic frame profile from shifting, shaking, or tilting during the opening process. The first bearing component may include a bearing mechanism and a clamping mechanism. The bearing mechanism is used to support the photovoltaic frame profile, and the clamping mechanism is used to clamp the photovoltaic frame profile. The clamping mechanism can adopt one or more of the following: a cylinder clamping structure, an electric clamping structure, a hydraulic clamping structure, or a mechanical clamping structure. This disclosure does not limit this.

[0049] In one or more embodiments of this disclosure, a first abutment support component is configured to be partially inserted into the inner cavity of the photovoltaic frame profile along its length. This provides support to the adjacent portion of the photovoltaic frame profile sidewall to be drilled when the drilling component drills a hole in the sidewall. Correspondingly, a portion of the photovoltaic frame profile sidewall aligns with the inner cavity of the photovoltaic frame profile. Thus, when the drilling component applies a drilling force to the sidewall of the photovoltaic frame profile, the first abutment support component provides support to the portion of the sidewall, thereby reducing the likelihood of the photovoltaic frame profile cracking or chipping at the drilling location.

[0050] In one or more embodiments of this disclosure, a first abutting support component and a first bearing component are configured to cooperate. The first bearing component is used to support, position, and clamp the exterior of the photovoltaic frame profile, while the first abutting support component is used to support a portion of the sidewall of the photovoltaic frame profile. Through this internal and external support cooperation, the overall stability of the photovoltaic frame profile during the hole-opening process can be improved, reducing sidewall cracking or edge chipping caused by hole-opening stress, and providing better foundation conditions for subsequent adhesive dispensing processes.

[0051] In one or more embodiments of this disclosure, the first bearing component, the first abutting support component, and the opening component can sequentially cooperate along the length of the photovoltaic frame profile. First, the first bearing component supports and clamps the photovoltaic frame profile; then, the first abutting support component partially inserts into the inner cavity of the photovoltaic frame profile and is positioned at a predetermined location to support a portion of the sidewall of the photovoltaic frame profile; then, the opening component makes an opening in the sidewall portion of the photovoltaic frame profile or at a predetermined location on the sidewall portion of the photovoltaic frame profile. After the opening is completed, the opening component resets, and the first abutting support component and the first bearing component retract. Optionally, the conveying mechanism can convey a photovoltaic frame profile with multiple through holes for subsequent opening operations.

[0052] In one aspect of the embodiments of this disclosure, the dispensing unit includes a second carrier component, a second abutment component, and a dispensing component. The second carrier component, the second abutment component, and the dispensing component are all connected to a frame. The second carrier component carries and holds a photovoltaic frame profile with multiple through holes. The second abutment component abuts against the end of the photovoltaic frame profile with multiple through holes. The dispensing component dispenses adhesive to at least a portion of the multiple through holes, and the adhesive at least partially covers the through holes.

[0053] In one or more embodiments of this disclosure, the second support component 302 can be used to support and clamp the outer side of the photovoltaic frame profile, thereby limiting the position of the photovoltaic frame profile and preventing the photovoltaic frame profile from shifting, shaking, or tilting during the dispensing process. Multiple second support components 302 can be provided, and each second support component 302 can also include a support structure and a clamping structure. The support structure is used to support the photovoltaic frame profile, and the clamping structure is used to clamp the photovoltaic frame profile. The clamping structure can also be one or more of a cylinder clamping structure, an electric clamping structure, a hydraulic clamping structure, or a mechanical clamping structure; this disclosure does not limit this.

[0054] In one or more embodiments of this disclosure, the second abutting component is configured to move along the length of the photovoltaic frame profile and abut against the end (i.e., the first end or the second end) of the photovoltaic frame profile, thereby forming an abutment limit on the end of the photovoltaic frame profile when the dispensing component dispenses adhesive to the through hole. Thus, when the dispensing component dispenses adhesive to the through hole location or applies a localized force to the photovoltaic frame profile, the second abutting component can provide abutment, limit, and positioning for the end (i.e., the first end or the second end) of the photovoltaic frame profile, thereby reducing the possibility of the photovoltaic frame profile shifting, deviating, or changing its posture during the dispensing process, which helps to ensure the accuracy of the dispensing position and the stability of the adhesive coverage.

[0055] In one or more embodiments of this disclosure, the second abutting component may abut against the end face or chamfered surface of the end of the photovoltaic frame profile and / or the adjacent area of ​​the end. Preferably, when the end of the photovoltaic frame profile has a 45° chamfered surface, the second abutting component may abut against the 45° chamfered surface to improve the stability of the abutting positioning of the end of the photovoltaic frame profile. Of course, in other embodiments, the second abutting component may also abut against other positions of the photovoltaic frame profile suitable for forming a limiting position, and this disclosure is not limited thereto.

[0056] In one or more embodiments of this disclosure, the second abutting component and the second supporting component are configured to cooperate. The second supporting component is used to support, position, and clamp the exterior of the photovoltaic frame profile, while the second abutting component is used to abut and position the end (i.e., the first end or the second end) of the photovoltaic frame profile. Through the cooperation of the second supporting component and the second abutting component, the photovoltaic frame profile can be positioned from two aspects: external support and clamping, and end-positioning along the length direction. This improves the positional stability of the photovoltaic frame profile during the dispensing process and helps to improve the alignment accuracy between the through-hole and the dispensing position.

[0057] In one or more embodiments of this disclosure, the second supporting component, the second abutting component, and the dispensing component can sequentially cooperate along the length of the photovoltaic frame profile. First, the second supporting component supports and clamps the photovoltaic frame profile; then, the second abutting component moves along the length of the photovoltaic frame profile and abuts against the end (i.e., the first end or the second end) of the photovoltaic frame profile to form a supporting clamp and end abutment; then, the dispensing component dispenses adhesive into at least some of the through holes on the photovoltaic frame profile, so that the adhesive at least partially covers the through holes. After dispensing is completed, the dispensing component resets, the second abutting component retracts, and the second supporting component releases the photovoltaic frame profile. Optionally, a conveying mechanism or other transfer mechanism can convey the dispensed photovoltaic frame profile for subsequent dispensing operations on the next photovoltaic frame profile with multiple through holes.

[0058] In one aspect of the embodiments of this disclosure, the first supporting component 301 includes a first supporting portion 3014 and a first clamping and releasing portion. The first supporting portion 3014 supports the photovoltaic frame profile, and the first clamping and releasing portion clamps or releases the photovoltaic frame profile; and / or, the first abutting support component includes: a first driving portion 502, a first guide block 503, a first guide seat 504, a first abutting portion 505, and a first insertion portion 506. The first driving portion 502 drives the first guide block 503 to move along the first guide seat 504. The first guide block 503 is connected to the first abutting portion 505. The first insertion part 506 is connected to the first abutting part 505, the first abutting part 505 abuts against or is inserted into the inner cavity of the photovoltaic frame profile, the first insertion part 506 is inserted into the inner cavity of the photovoltaic frame profile and supports the side wall of the photovoltaic frame profile; and / or, the opening assembly includes an opening device 202, a first mounting plate 204, and a plurality of needles 206, the opening device 202 is connected to the first mounting plate 204, the first mounting plate 204 is connected to the plurality of needles 206, the opening device 202 drives the plurality of needles 206 to pass through the side wall of the photovoltaic frame profile to form a plurality of through holes in the side wall of the photovoltaic frame profile.

[0059] In one or more embodiments of this disclosure, the first support portion 3014 can serve as a support mechanism and can be used to support the photovoltaic frame profile during the opening process. The first clamping release portion can be disposed adjacent to the first support portion 3014 and can serve as a clamping mechanism. The first clamping release portion can cooperate with the first support portion to clamp the photovoltaic frame profile in the clamping state and release the clamping of the photovoltaic frame profile in the releasing state.

[0060] For example, the first clamping and releasing part includes: a first cylinder 3011 and a first cylinder gripper. The first cylinder gripper includes a first cylinder, a first gripper 3012, and a second gripper 3013. The first cylinder 3011 is connected to the first cylinder gripper. The first gripper 3012 and the second gripper 3013 are connected to opposite sides of the first cylinder. The first cylinder 3011 drives the first cylinder gripper to move up and down towards or away from the photovoltaic frame profile. The first cylinder drives the first gripper 3012 and the second gripper 3013 to move closer to or further away from each other to clamp or release multiple photovoltaic frame profiles with multiple through holes. Thus, the first clamping and releasing part and the first bearing part 3014 cooperate. The first clamping and releasing part can be used to achieve positioning and clamping of the photovoltaic frame profile and release after the hole-making process is completed. This can prevent the photovoltaic frame profile from shifting or shaking during the hole-making process and maintain the stability of the photovoltaic frame profile during the hole-making process.

[0061] In one or more embodiments of this disclosure, the first drive unit 502 is connected to the frame. Exemplarily, the first drive unit 502 is connected to the frame 10 or the mounting part 102 via a first connecting plate 501. The first drive unit 502 drives the first guide block 503 to move along the first guide seat 504. The first guide seat 504 can guide or limit the movement of the first guide block 503, causing the first guide block 503 to move in a predetermined direction. Preferably, the predetermined direction is the same as or substantially the same as the length direction of the photovoltaic frame profile, thereby facilitating the insertion of the first insertion part 506 into the inner cavity of the photovoltaic frame profile.

[0062] In one or more embodiments of this disclosure, the first abutting portion 505 is connected to the first guide block 503 and the first insertion portion 506 on both sides. The first abutting portion 505 is located between the first guide block 503 and the first insertion portion 506. The first abutting portion 505 can be used to abut against the photovoltaic frame profile. Specifically, the first abutting portion 505 can abut against the end or chamfered surface or the area near the end of the photovoltaic frame profile, thereby limiting the insertion position of the first insertion portion 506. This is beneficial to improving the fitting accuracy between the first insertion portion 506 and the inner cavity of the photovoltaic frame profile. The first insertion portion 506 can be inserted into the predetermined position in the inner cavity of the photovoltaic frame profile more accurately.

[0063] In another or more embodiments of this disclosure, the first abutment portion 505 may also be at least partially inserted into the inner cavity of the photovoltaic frame profile. Specifically, when the first driving unit 502 drives the first guide block 503 to move along the first guide seat 504, the first abutment portion 505 extends at least partially into the inner cavity entrance of the photovoltaic frame profile. After the first abutment portion 505 is at least partially inserted into the inner cavity of the photovoltaic frame profile, it can cooperate with the first insertion portion 506 to form a composite support for the inner cavity of the photovoltaic frame profile. Specifically, the first abutment portion 505 can form internal support for the inner cavity entrance area of ​​the photovoltaic frame profile, while the first insertion portion 506 further extends to a predetermined support position to form support for the adjacent portion corresponding to the area to be opened. Through the cooperation of the first abutment portion 505 and the first insertion portion 506, the overall support of the photovoltaic frame profile during the opening process can be further improved.

[0064] In another or more embodiments of this disclosure, at least a portion of the outer contour of the first abutment portion 505 may be adapted to at least a portion of the contour at the entrance of the inner cavity of the photovoltaic frame profile, thereby providing guidance and / or support during the insertion of the first abutment portion 505. Of course, the first abutment portion 505 may also adopt a block-shaped insertion structure, a plate-shaped insertion structure, or other structures that can be inserted into the inner cavity and form a guiding and / or supporting function, and this disclosure does not limit this.

[0065] In one or more embodiments of this disclosure, such as Figure 6As shown, the first insertion part 506 is used to insert into the inner cavity of the photovoltaic frame profile and to provide support for part of the side wall of the photovoltaic frame profile. The first insertion part 506 includes: a body 5061 and a receiving groove 5062. The receiving groove 5062 is formed on 5061. The needle 206 passes through the side wall of the photovoltaic frame profile and is at least partially located in the receiving groove 5062. Multiple receiving grooves 5062 are provided, and at least two of the multiple receiving grooves 5062 are parallel to each other. Each receiving groove 5062 can correspond to multiple needles. The boundary of the receiving groove 5062 can be formed to form a closed groove structure, or the boundary of the receiving groove 5062 can be only partially formed to form a non-closed groove structure, that is, the receiving groove 5062 can be formed with an opening.

[0066] Specifically, when the opening component applies an opening force to the side wall of the photovoltaic frame profile, the receiving groove 5062 corresponds to the area to be opened on the side wall of the photovoltaic frame profile. Accordingly, the first insertion part 506 can provide support for the portion adjacent to the area to be opened on the side wall of the photovoltaic frame profile. In other words, the body 5061 can provide support for the portion adjacent to the area to be opened on the side wall of the photovoltaic frame profile. This completes the insertion of the first abutting support component into the inner cavity of the photovoltaic frame profile and supports the portion of the side wall of the photovoltaic frame profile, thereby reducing the possibility of the photovoltaic frame profile cracking at the opening position.

[0067] In one or more embodiments of this disclosure, the outer contour of the first insertion part 506 may be adapted to at least a portion of the contour of the inner cavity of the photovoltaic frame profile to improve support stability. The first insertion part 506 may adopt a block support structure, a plate support structure or other structures that can be inserted into the inner cavity and form a support function. This disclosure does not limit this.

[0068] In one or more embodiments of this disclosure, the perforator 202 is used to drive the needle 206 to move, and the first mounting plate 204 is used to connect the perforator 202 and the needle 206. Optionally, the perforation assembly further includes a first support 201, a guide rod 2031, a guide cylinder 2032, and a second connecting plate 205. The perforator 202 is connected to the first support 201 and the first mounting plate 204. The first mounting plate 204 is connected to the second connecting plate 205, and the second connecting plate 205 connects to a plurality of needles 206. The guide rod 2031 is connected to the first mounting plate 204, and the guide cylinder 2032 is connected to the first support 201. The guide rod 2031 guides the movement relative to the guide cylinder 2032.

[0069] Exemplarily, the hole punch 202 may be or include a cylinder, electric cylinder, hydraulic cylinder, or other drive device capable of outputting (reciprocating) linear motion, and this disclosure is not limited thereto. For example, when the hole punch 202 is activated, it drives the first mounting plate 204 and the needle 206 to reciprocate in the direction toward and away from the photovoltaic frame profile; wherein, when the needle 206 moves toward the photovoltaic frame profile, it passes through the side wall of the photovoltaic frame profile to form multiple through holes in the side wall of the photovoltaic frame profile; when the needle 206 moves away from the photovoltaic frame profile, it retracts from the side wall of the photovoltaic frame profile to complete one punching and reset. The hole punch can serve as the aforementioned punching mechanism.

[0070] In one or more embodiments of this disclosure, preferably, the piercing needle 206 can be conical, meaning that the outer diameter of the piercing needle 206 gradually increases from its front end to its rear end along its piercing direction. This facilitates the gradual formation of an opening as the piercing needle 206 passes through the sidewall of the photovoltaic frame profile, reducing the instantaneous impact force and helping to minimize chipping or burrs generated during the opening process. Exemplarily, the front end of the piercing needle 206 can be a pointed structure, and the rear end can be a rod-shaped connecting structure to facilitate connection with the second connecting plate 205. Of course, in other embodiments, the piercing needle 206 can also be pyramidal or other shapes capable of achieving the piercing and opening function; this disclosure does not limit this.

[0071] In one or more embodiments of this disclosure, the needle 206 can be one, two, or more. When there are two or more needles, the multiple needles 206 can be arranged at a predetermined interval to form multiple through holes on the sidewall of the photovoltaic frame profile at one time. The arrangement of the multiple needles 206 can be a single row, a double row, or an array arrangement, and this disclosure does not limit this.

[0072] In one or more embodiments of this disclosure, when multiple through holes need to be formed, multiple through holes can be formed at once or in multiple stages. For example, when multiple needles 206 correspond to the positions of multiple through holes, multiple through holes can be opened at once; when the number of holes opened at one time is less than the target number of through holes, the opening of multiple through holes can be completed in stages by adjusting the relative positions of the photovoltaic frame profile and the opening assembly, which is not limited in this respect.

[0073] In one or more embodiments of this disclosure, the first abutment support assembly is configured to cooperate with the opening assembly. When the first insertion portion 506 is inserted into the inner cavity of the photovoltaic frame profile and provides support to the sidewall portion of the photovoltaic frame profile, the opening device 202 drives the needle 506 through the sidewall of the photovoltaic frame profile to form multiple through holes. Because the first insertion portion 506 provides support in the adjacent portion of the area to be opened, sidewall cracking or edge chipping caused by opening stress can be reduced.

[0074] In one or more embodiments of this disclosure, the first bearing component, the first abutting support component, and the opening component can cooperate sequentially. First, the first bearing component supports the photovoltaic frame profile, and the first clamping release component clamps the photovoltaic frame profile. Then, the first driving component 502 drives the first guide block 503 to move along the first guide seat 504, so that the first abutting component 505 abuts against or at least partially inserts into the inner cavity of the photovoltaic frame profile, and the first insertion component 506 inserts into the inner cavity of the photovoltaic frame profile. Next, the opening device 202 actuates, causing the first mounting plate 205 and the needle 206 to move towards the sidewall of the photovoltaic frame profile, so that the needle 206 passes through the sidewall of the photovoltaic frame profile, thereby forming a through hole at a corresponding position on the sidewall of the photovoltaic frame profile. After the opening is completed, the opening device 202 resets, the first driving component 502 drives the first insertion component 506 to retract, and the first clamping release component releases the photovoltaic frame profile for subsequent opening operations.

[0075] Therefore, by setting the first bearing component to include a first bearing part and a first clamping release part, setting the first abutting support component to include a first driving part, a first guide block, a first guide seat, a first abutting part and a first insertion part, and setting the opening component to include an opening device, a first mounting plate and multiple needles, it is possible to achieve stable bearing clamping, side wall support and side wall opening of photovoltaic frame profiles, and provide better basic conditions for subsequent dispensing processes.

[0076] In one aspect of the embodiments of this disclosure, the second carrier component 302 includes a second carrier portion and a second clamping release portion. The second carrier portion carries a photovoltaic frame profile with multiple through holes, and the second clamping release portion clamps or releases the photovoltaic frame profile with multiple through holes. And / or, the second abutting component includes a second driving portion 602 and a second abutting portion 603. The second driving portion 602 is connected to the second abutting portion 603, and the second abutting portion 603 abuts against the end of the photovoltaic frame profile with multiple through holes. And / or, the dispensing component includes a moving portion and a dispensing portion 705. The moving portion moves the dispensing portion 705, and the dispensing portion 705 dispenses adhesive to at least a portion of the multiple through holes, with the adhesive at least partially covering the through holes.

[0077] In one or more embodiments of this disclosure, the aforementioned dispensing actuator may be an adhesive dispensing section 705 or a part thereof, that is, the adhesive dispensing section 705 may include or be an adhesive dispensing actuator, the moving section may be a moving mechanism, and the second bearing section may also be a bearing structure, which can be used to support the photovoltaic frame profile with multiple through holes so that the photovoltaic frame profile maintains a predetermined position during the dispensing process; the second clamping release section may be a clamping structure, and the second clamping release section is disposed adjacent to the second bearing section so as to clamp the photovoltaic frame profile in the bearing state and release the clamping of the photovoltaic frame profile in the release state.

[0078] Exemplarily, the structure and connection method of the second support component 302 and the first support component 301 can be completely identical, the structure and connection method of the second support part and the first support part can be completely identical, and the structure and connection method of the second clamping release part can be completely identical to that of the first clamping release part. The second clamping release part includes: a second cylinder and a second cylinder gripper. The second cylinder gripper includes a second cylinder, a first gripper, and a second gripper. The second cylinder is connected to the second cylinder gripper. The two opposite sides of the second cylinder are connected to the first gripper and the second gripper. The second cylinder drives the second cylinder gripper to rise and fall to approach or move away from the multiple photovoltaic frame profiles with multiple through holes. The second cylinder drives the first gripper and the second gripper to approach or move away from each other to clamp or release the multiple photovoltaic frame profiles with multiple through holes. Thus, the second clamping release part and the second support part cooperate, and the second clamping release part can realize the positioning and clamping of the photovoltaic frame profiles with multiple through holes and the release after dispensing. This can reduce the displacement and shaking of the photovoltaic frame profiles during the dispensing process and help improve the stability of the dispensing process.

[0079] In one or more embodiments of this disclosure, the second abutment component may further include: a third bracket 601, a second drive unit 602 connected to the third bracket 601, the third bracket 601 connected to the frame 10 or the mounting part 102, and the second drive unit 602 providing abutment power to drive the second abutment part 603 to move toward the photovoltaic frame profile with multiple through holes and form an abutment with the end of the photovoltaic frame profile. Exemplarily, the second drive unit 602 may be a cylinder, an electric cylinder, a hydraulic cylinder, or other drive device capable of outputting linear motion, and this disclosure is not limited thereto.

[0080] In one or more embodiments of this disclosure, the second abutment portion 603 is used to abut against the end of a photovoltaic frame profile with multiple through holes to form end positioning and abutment of the photovoltaic frame profile. The second abutment portion 603 may abut against the end face, the chamfered surface of the end, or the adjacent area of ​​the end of the photovoltaic frame profile. Preferably, when the end of the photovoltaic frame profile has a 45° chamfered surface, the second abutment portion 603 may abut against the 45° chamfered surface of the end to improve the stability of abutment and positioning.

[0081] In one or more embodiments of this disclosure, the second abutting component and the second supporting component 302 are configured to cooperate. The second supporting component 302 is used to externally support, position, and clamp the photovoltaic frame profile with multiple through holes. The second abutting component is used to abut, position, or limit the ends of the photovoltaic frame profile. Through their cooperation, the photovoltaic frame profile can be positioned from both external support and clamping and length-direction end limiting aspects, thereby improving the stability of the photovoltaic frame profile during the dispensing process and improving the alignment accuracy between the through holes and the dispensing position.

[0082] In one or more embodiments of this disclosure, the dispensing assembly includes a second support 701, a movable part, and a dispensing part 705. The movable part is connected to the second support 701, and the second support 701 is connected to the connecting frame 10 or the mounting part 102. The dispensing part is connected to the movable part 705, and the movable part is used to drive the dispensing part 705 to move to a predetermined position. Specifically, the movable part can drive the dispensing part 705 to move in a single direction, or it can drive the dispensing part 705 to move in at least two directions, such as the X direction, and / or the Y direction, and / or the Z direction, to adapt to the dispensing requirements of different through-hole positions. For example, the movable part may include an X-direction moving module 704; and / or a Y-direction moving module 702; and / or a Z-direction moving module 703. Each moving module includes a slide rail slider mechanism and a motor screw nut pair mechanism. The moving modules are prior art, and this disclosure does not limit or elaborate on them.

[0083] In one or more embodiments of this disclosure, the dispensing part 705 is used to dispense adhesive to a corresponding position of a through hole to dispense adhesive into at least a portion of the through holes. Specifically, the dispensing part 705 may include at least one of a dispensing nozzle, a filling nozzle, or a spray nozzle. Preferably, the dispensing end of the dispensing part 705 is disposed towards the through hole to facilitate more accurate application of the adhesive to the through hole position. By dispensing adhesive into the through hole through the dispensing part 705, the adhesive can fall into the opening of the through hole, and the adhesive extends into the through hole under its own gravity, thereby forming at least partial coverage or at least partial filling of the through hole.

[0084] In one or more embodiments of this disclosure, when it is necessary to dispense adhesive to multiple through holes, the adhesive can be dispensed to the multiple through holes simultaneously at once, or the adhesive can be dispensed to the multiple through holes sequentially in multiple stages. For example, when the dispensing part 705 includes multiple dispensing ports corresponding to the positions of the multiple through holes, the dispensing of multiple through holes can be completed at once; when the number of adhesive dispensed in a single operation is less than the target number of through holes, the dispensing of multiple through holes can be completed in stages by adjusting the relative positions of the photovoltaic frame profile and the dispensing assembly, and this disclosure does not limit this process.

[0085] In one or more embodiments of this disclosure, the second supporting component 302, the second abutting component, and the dispensing component can operate sequentially. First, the second supporting component supports the photovoltaic frame profile with multiple through holes, and the second clamping and releasing component clamps the photovoltaic frame profile. Then, the second driving component 602 drives the second abutting component 603 to move towards the photovoltaic frame profile and abut against the end of the photovoltaic frame profile, thereby positioning and abutting the end of the photovoltaic frame profile. Next, the moving component moves the dispensing component 705 to a predetermined dispensing position, and the dispensing component 705 dispenses adhesive onto at least a portion of the through holes, with the adhesive at least partially covering the through holes. After dispensing is completed, the dispensing component 705 resets, the second abutting component 603 retracts, and the second clamping and releasing component releases the dispensed photovoltaic frame profile for subsequent dispensing operations at the next dispensing position.

[0086] Therefore, by using the second bearing component 302, which includes a second bearing part and a second clamping release part, and the second abutting component, which includes a second driving part 602 and a second abutting part 603, and the dispensing component, which includes a moving part and a dispensing part 705, stable bearing clamping, end abutment limiting, and dispensing of multiple through holes in a photovoltaic frame profile with multiple through holes can be achieved, thereby improving the stability of the dispensing process.

[0087] Secondly, such as Figure 7 As shown, a photovoltaic frame profile dispensing method, using or not using any of the photovoltaic frame profile dispensing devices described in the first aspect above, includes the following steps: Step S100: Make holes in the photovoltaic frame profile to form multiple through holes on the sidewall of the photovoltaic frame profile; Step S200: Apply adhesive to at least a portion of the through holes, such that the adhesive at least partially covers the through holes.

[0088] In one or more embodiments of this disclosure, the technical content of step S100 can be found in the aforementioned opening unit; the technical content of step S200 can be found in the aforementioned dispensing unit, and this disclosure will not repeat it here.

[0089] In one or more embodiments of this disclosure, when the method is implemented using the aforementioned photovoltaic frame profile dispensing device, the photovoltaic frame profile can first be perforated by the perforation unit to form multiple through holes on its sidewalls; subsequently, the dispensing unit dispenses adhesive onto at least a portion of the multiple through holes, with the adhesive at least partially covering the through holes. This allows for the continuous execution of the perforation and dispensing processes, forming a processing method of perforation followed by dispensing. This enables the dispensing process to target the already formed through holes, maintaining the targeted coverage of the through holes, which is beneficial for improving the sealing performance, structural or operational stability of the through hole area, reducing intermediate transfer links and manual intervention, and improving production efficiency and the yield of photovoltaic frame profile products.

[0090] In one aspect of this disclosure, step S100 includes: Step S101: The photovoltaic frame profile is clamped and supported, and the part supporting the side wall of the photovoltaic frame profile is also supported; Step S102: Make openings in the sidewall of the photovoltaic frame profile to form multiple through holes in the sidewall of the photovoltaic frame profile.

[0091] In one or more embodiments of this disclosure, steps S101 and S102 can be executed sequentially. First, the photovoltaic frame profile is clamped and supported, and a portion of the sidewall of the photovoltaic frame profile is supported. Then, holes are made in the sidewall of the photovoltaic frame profile to form multiple through holes. After the holes are made, the support and / or clamping of the photovoltaic frame profile can be released, and the photovoltaic frame profile with multiple through holes can be conveyed to the next dispensing processing station for subsequent processing.

[0092] In one or more embodiments of this disclosure, in step S101, the photovoltaic frame profile can be supported, clamped, and positioned to ensure that the photovoltaic frame profile is in a predetermined processing posture before drilling. Specifically, step S101 may include: a first supporting component supporting and clamping the photovoltaic frame profile (i.e., a first supporting part supporting the photovoltaic frame profile, and a first clamping release part clamping the photovoltaic frame profile), and a first abutting support component partially inserted into the inner cavity of the photovoltaic frame profile to support the side wall of the photovoltaic frame profile. Exemplarily, the portion of the first abutting support component partially inserted into the inner cavity of the photovoltaic frame profile to support the side wall of the photovoltaic frame profile may include: a first driving part 502 driving a first guide block 503 to move along a first guide seat 504, so that the first abutting part 505 abuts against or at least partially inserts into the inner cavity of the photovoltaic frame profile, and the first insertion part 506 inserts into the inner cavity of the photovoltaic frame profile, forming support for the inner wall of the inner cavity of the photovoltaic frame profile, so as to provide a reverse support force to the side wall when drilling. Therefore, the first load-bearing component can prevent the photovoltaic frame profile from shifting, shaking, or tilting excessively during the subsequent hole-making process, thus providing a stable processing foundation for the side wall opening.

[0093] In one or more embodiments of this disclosure, step S102 may include: the opening assembly opening a hole in the sidewall of the photovoltaic frame profile. More specifically, it may include: the opening device 202 driving the needle 206 through the sidewall of the photovoltaic frame profile to form multiple through holes in the sidewall of the photovoltaic frame profile, that is: the opening device 202 moves the first mounting plate 204 and the needle 206 toward the sidewall of the photovoltaic frame profile, so that the needle 206 passes through the sidewall of the photovoltaic frame profile, thereby forming a through hole at the corresponding position of the sidewall of the photovoltaic frame profile. During the process of the opening device 202 driving the needle 206 to open the sidewall of the photovoltaic frame profile, since the first abutment support assembly has been partially inserted into the inner cavity of the photovoltaic frame profile and provides support to the sidewall portion of the photovoltaic frame profile, the needle 206 can provide a reverse support force to the opening position during the process of passing through the sidewall of the photovoltaic frame profile, thereby reducing the possibility of cracking or edge chipping caused by the opening stress.

[0094] In one or more embodiments of this disclosure, step S102 can be performed after step S101 is completed. That is, after the first supporting component supports and clamps the photovoltaic frame profile, and the first abutting support component provides support for a portion of the sidewall of the photovoltaic frame profile, the opening component then opens a hole in the sidewall of the photovoltaic frame profile. By clamping and supporting first and then opening the hole, the stability of the opening process can be improved, thereby improving the processing consistency of multiple through holes.

[0095] In one aspect of this disclosure, step S200 includes: Step S201: The carrier clamps the photovoltaic frame profile with multiple through holes and abuts against the end of the photovoltaic frame profile with multiple through holes; Step S202: Apply adhesive to at least a portion of the through holes, so that the adhesive falls into the through holes and at least partially covers the through holes.

[0096] In one or more embodiments of this disclosure, after forming the plurality of through holes, at least a portion of the through holes are treated with adhesive to at least partially cover the through holes. Specifically, the adhesive may cover the opening of the through hole and extend into the through hole as needed to partially or completely cover, partially or completely block, or partially or completely fill the through hole.

[0097] In one or more embodiments of this disclosure, steps S201 and S202 can be performed sequentially. First, a photovoltaic frame profile with multiple through holes is clamped and abutted against the end of the photovoltaic frame profile with multiple through holes; then, adhesive is applied to at least a portion of the through holes, allowing the adhesive to fall into the through holes and at least partially cover them. After the adhesive application is completed, the abutment and / or clamping of the photovoltaic frame profile with multiple through holes can be released, and the photovoltaic frame profile can be conveyed to the next processing position for subsequent processing.

[0098] In one or more embodiments of this disclosure, in step S201, a photovoltaic frame profile with multiple through holes can be supported, clamped, and positioned to ensure that the photovoltaic frame profile with multiple through holes is in a predetermined dispensing posture before dispensing adhesive. Specifically, step S201 may include: a second supporting component 302 supporting and clamping the photovoltaic frame profile with multiple through holes, i.e., a second supporting part supporting the photovoltaic frame profile with multiple through holes, and a second clamping release part clamping the photovoltaic frame profile with multiple through holes; and a second abutting component abutting the end of the photovoltaic frame profile with multiple through holes. More specifically, it may include: a second driving part 602 driving a second abutting part 603 to move toward the photovoltaic frame profile with multiple through holes, so that the second abutting part 603 abuts against the end of the photovoltaic frame profile with multiple through holes. Therefore, the second bearing component 302 can prevent the photovoltaic frame profile from shifting, shaking, or tilting during the subsequent dispensing process, and the second abutting component can position and abut the photovoltaic frame profile in the length direction, thereby providing a stable processing foundation for through-hole dispensing.

[0099] In one or more embodiments of this disclosure, step S202 may include: the dispensing assembly dispensing adhesive to at least a portion of the through holes among a plurality of through holes. More specifically, it may include: the moving part driving the dispensing part 705 to a predetermined position, the dispensing part 705 outputting adhesive to at least a portion of the through holes among the plurality of through holes, so that the adhesive falls into the through holes and at least partially covers the through holes. During the dispensing process of the dispensing part 705 to at least a portion of the through holes among the plurality of through holes, the second bearing assembly 302 and the second abutting assembly have respectively formed bearing clamping and end abutment on the photovoltaic frame profile with the plurality of through holes. Thus, during the process of the dispensing part 705 outputting adhesive to the through holes, it can ensure that the photovoltaic frame profile maintains a relatively stable spatial position, reducing the possibility of adhesive misalignment or insufficient coverage caused by the movement, offset, or posture change of the photovoltaic frame profile.

[0100] In one or more embodiments of this disclosure, step S202 can be performed after step S201 is completed. That is, after the second supporting component 302 supports and clamps the photovoltaic frame profile with multiple through holes and the second abutting component abuts the ends of the photovoltaic frame profile with multiple through holes, the dispensing component then dispenses adhesive to at least some of the through holes. By first supporting, clamping, and abutting the ends, and then dispensing, the stability of the dispensing process can be improved, thereby improving the targeted coverage of the adhesive to the multiple through holes. If necessary, after dispensing, the adhesive can also be cured and / or inspected to ensure the molding effect after dispensing the through holes.

[0101] Therefore, by carrying and clamping the photovoltaic frame profile with multiple through holes in step S201 and abutting its ends, and by using the dispensing assembly to dispense adhesive to at least some of the through holes in step S202, the photovoltaic frame profile can maintain good positioning stability during the dispensing process, which is beneficial to improving the accuracy and coverage of the adhesive falling into and covering the through holes.
