Description

Technical Field

[0001] This invention belongs to the field of photovoltaic bracket parts processing technology, and specifically refers to an automatic bonding device for L-shaped parts. Background Technology

[0002] In the field of photovoltaic bracket installation, L-shaped parts 600 (see [reference needed]) are specifically designed for rooftop photovoltaic brackets. Figure 14 Assembly of its waterproof pad 700 (usually made of rubber) (see...) Figure 15 The assembly of the rooftop photovoltaic system is a crucial step in ensuring its stability and waterproofing. Currently, this assembly process relies primarily on manual labor, requiring workers to manually align the mounting holes 601 of the L-shaped component 600 with the positioning points of the waterproof pad 700 before using tools to secure them together. This manual method is not only inefficient and unsuitable for large-scale production, but also prone to errors due to human intervention, leading to insufficient precision in the bonding process.

[0003] When the fitting precision between the L-foot part 600 and the waterproof pad 700 is insufficient, on the one hand, it will weaken the synergistic fixing effect between the L-foot part 600 and the waterproof pad 700, thereby affecting the stability of the subsequent installation of the photovoltaic bracket; on the other hand, it will also damage the sealing integrity of the waterproof pad 700, causing the roof photovoltaic system to be prone to water leakage due to assembly gaps.

[0004] Currently, there is a lack of automated assembly equipment for this specific kit in existing technologies, which cannot effectively solve the pain points of manual assembly in terms of efficiency and accuracy, thus restricting the improvement of production quality and capacity of photovoltaic bracket supporting components. Summary of the Invention

[0005] The main objective of this invention is to provide an automatic bonding device for L-shaped parts, which solves the problems of low efficiency, insufficient precision and unstable operation quality of manual assembly. It can automatically bond waterproof pads to L-shaped parts, thereby improving both bonding efficiency and bonding precision, significantly reducing labor costs and increasing the degree of industrial automation.

[0008] Preferably, the part slot is provided with a guide surface at the opening of the flip seat end face; the height of the part slot is greater than the thickness of the L-shaped part.

[0009] Preferably, the part flipping device further includes a mounting base and a limiter; the flipping base is disposed between the end of the first adapter and the mounting base; the limiter is horizontally adjustable and mounted on the mounting base, with its height set to be equal to the shorter end of the flipped L-foot part, and attracts the L-foot part to the inner wall of the part slot by magnetic attraction.

[0010] The flip-up seat and the third push rod are mounted on the same base. The base is provided with a rotating shaft for driving the flip-up seat. The rotating shaft and the third push rod are arranged vertically parallel to each other.

[0011] The gasket transport device includes an mounting platform, a damping disc, a peeling block, a third conveyor belt, pressure rollers, and a second step controller. The damping disc is located at one end of the side of the mounting platform and is used to wind the release paper. The adhesive side of the waterproof pad is attached to the release paper, and a gap is reserved between adjacent waterproof pads. The peeling block is located at the other end of the side of the mounting platform. The third conveyor belt is located on the side of the mounting platform and below the damping disc and the peeling block. At least one pressure roller is arranged close to the top of its belt, and the pressure roller is rotatably mounted on the side of the mounting platform. The second step controller is located between the damping disc and the peeling block and is used to detect the gap between the waterproof pads and control the third conveyor belt.

[0016] After adopting the above technical solution, the present invention has the following technical effects: (1) In view of the fact that the L-shaped part has two perpendicular plates of different lengths, the present invention has specially designed a transportation and flipping mechanism corresponding to the L-shaped part. During transportation, the longer end of the L-shaped part is in a horizontal state and the shorter end is in a vertical state. This ensures that the center of gravity of the L-shaped part is closer to the upper surface of the belt conveyor and the transfer table, and there will be no shaking during the movement. Then, when it moves to the flipping seat, it is flipped 90° to flip the shorter end to a horizontal state, that is, the bonding surface of the L-shaped part is facing upwards, which facilitates the automatic bonding of the waterproof pad by the bonding device 300. Finally, the present invention can realize the entire process of automated bonding, which can improve the assembly efficiency and stable operation, and meet the needs of large-scale production.

[0017] (2) When L-foot parts are transferred between different devices, they are mostly driven by push rods. The execution interval of each process can be controlled by the action frequency of the push rods, and the L-foot parts can be prevented from deflecting during the conveying process, ensuring the smooth connection of the process and preventing jamming.

[0018] (3) The first belt conveyor and the second belt conveyor of the present invention can be easily connected to the existing production line to realize the transformation of the production line and reduce the manufacturer's cost; the present invention can stabilize product quality, eliminate differences in manual operation, reduce the probability of subsequent installation failure of photovoltaic brackets, and improve the overall system reliability through automated and standardized operation process.

Detailed Implementation

[0035] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0036] refer to Figures 1 to 13 As shown, the present invention discloses an automatic bonding device for L-shaped parts, including a pad transport device 100, a part transport device 200, a bonding device 300, a part flipping device 400, and a feeding device 500. Gasket transport device 100 is used to transport waterproof gasket 700 that is picked up by patch assembly device 300; The parts transport device 200, the parts flipping device 400, and the unloading device 500 are connected sequentially according to the production process to transport the L-shaped parts 600. The parts transport device 200 and the unloading device 500 transport the L-shaped parts 600 in a horizontal position, so that the longer end of the L-shaped parts 600 is attached to the transport bearing surface of the device. The parts flipping device 400 flips the L-shaped parts 600 by 90°, so that the shorter end of the L-shaped parts 600 is flipped upward by 90°. The parts transport device 200 includes a first belt conveyor 201, a first step controller 202, and a first push rod 203; the first belt conveyor 201 is used to transport L-shaped parts 600; the first step controller 202 is used to detect the gaps between L-shaped parts 600 and control the first belt conveyor 201; the first push rod 203 is located on one side of the end of the first belt conveyor 201. The parts flipping device 400 includes a first transfer platform 401, a flipping seat 402, a second push rod 403, a third push rod 404, a second transfer platform 405, and a fourth push rod 406. The first transfer platform 401 is located on the other side of the end of the first belt conveyor 201, and its upper surface is flush with the upper surface of the first belt conveyor 201. The first push rod 203 pushes the L-shaped parts 600 at the end of the first belt conveyor 201 one by one into the first transfer platform 401. The flipping seat 402 and the second push rod 403 are respectively located at both ends of the first transfer platform 401, and the third push rod 404 is located on one side of the flipping seat 402. See also... Figures 9 to 12 The flip base 402 is flipped 90°, and its end face is provided with a part slot 4021 for inserting the L-foot part 600. A push rod through hole 4022 for inserting the third push rod 404 is provided through between the two sides of the flip base 402. The part slot 4021 communicates with the push rod through hole 4022 and extends to the other side of the flip base 402. The second adapter 405 is provided on the other side of the flip base 402 and is used to receive the L-foot part 600 pushed out by the third push rod 404. See Figures 9 to 11In actual operation, when the flip seat 402 flips 90°: if the part slot 4021 is horizontally facing the second push rod 403, the corresponding action is that the second push rod 403 pushes the L-foot part 600 on the first adapter 401 into the part slot 4021 of the flip seat 402; if the part slot 4021 is facing upward, the corresponding action is to position the L-foot part 600 and attach the waterproof pad 700, and then the third push rod 404 inserts into the push rod through hole 4022 and pushes the L-foot part 600 with the waterproof pad 700 attached out of the part slot 4021, so that it falls into the second adapter 405; The unloading device 500 includes at least a second belt conveyor 501 for conveying L-shaped parts 600. The second belt conveyor 501 and the fourth push rod 406 are respectively located at both ends of the second transfer table 405. The fourth push rod 406 pushes the L-shaped parts 600 with waterproof pads 700 attached on the second transfer table 405 (pushed out from the flipping seat 402 by the third push rod 404) into the second belt conveyor 501. Then, the second belt conveyor 501 conveys the L-shaped parts 600 with waterproof pads 700 attached to the subsequent process for inspection and / or storage and sorting. The patch device 300 is used to pick up the waterproof pad 700 and attach it to the L-foot part 600 that is inserted into the flip seat 402 and flipped 90°.

[0037] Through the above solution, this invention addresses the characteristic of L-shaped parts having two perpendicular plates of different lengths. A dedicated transport and flipping mechanism is designed to accommodate the L-shaped part, ensuring that the longer end of the L-shaped part 600 is horizontal and the shorter end is vertical during transport. This ensures that the center of gravity of the L-shaped part 600 is closer to the upper surface of the conveyor belt and transfer table, preventing swaying during movement. Upon reaching the flipping seat 402 (bonding station), it is flipped 90° to bring the shorter end to a horizontal position, with the bonding surface of the L-shaped part 600 facing upwards. This facilitates the automatic bonding of the waterproof pad by the bonding device 300. Ultimately, this invention achieves automated bonding throughout the entire process, improving assembly efficiency. Furthermore, it operates stably, meeting the needs of large-scale production; when the L-foot part 600 is transferred between different devices, it is mostly driven by push rods, and the execution interval of each process can be controlled by the action frequency of the push rods, which can also prevent the L-foot part 600 from deflecting during the conveying process, ensuring the smooth connection of processes and preventing machine jamming; the first belt conveyor 201 and the second belt conveyor 501 of this invention can be easily connected to existing production lines, realizing the transformation of production lines and reducing the manufacturer's costs; through automated and standardized operation processes, this invention can stabilize product quality, eliminate differences in manual operation, reduce the probability of subsequent installation failures of photovoltaic brackets, and improve the overall system reliability.

[0038] The following illustrates specific embodiments of the present invention.

[0039] See Figures 7 to 12 The part flipping device 400 of the present invention is shown: The aforementioned part flipping device 400 also includes a first positioner 407 disposed above the flipping base 402. The first positioner 407 is used to detect the position of the L-shaped part 600 on the flipping base 402 and send the position information to the patching device 300 so that the patching device 300 can position the specific position of the L-shaped part 600 after picking up the waterproof pad 700, thereby improving the bonding accuracy. This ensures assembly accuracy, precisely controls the bonding position of the L-shaped part 600 and the waterproof pad 700, and avoids waterproof seal failure. Specifically, the first positioner 407 can be a visual inspection device such as a CCD camera, which uses high-definition imaging technology to capture real-time images of the L-shaped part 600 on the flipping base 402, and then uses image processing algorithms to analyze the position coordinates of key feature points such as the part edge and mounting hole 601 to form the position information of the L-shaped part 600.

[0040] Furthermore, in order to facilitate the second push rod 403 to push the L-foot part 600 on the first adapter 401 into the part slot 4021 of the flip seat 402, the part slot 4021 is provided with a guide surface 4023 at the opening on the end face of the flip seat 402, so that the inlet of the part slot 4021 presents an outwardly flared shape similar to a flared mouth, making it easier for the L-foot part 600 to be inserted into the part slot 4021; at the same time, the height of the part slot 4021 is greater than the thickness of the L-foot part 600.

[0041] Secondly, the aforementioned part flipping device 400 also includes a mounting base 408 and a limiter 409; the flipping base 402 is disposed between the end of the first adapter 401 and the mounting base 408, and the limiter 409 is horizontally adjustable on the mounting base 408, with its height set to be equal to the shorter end of the flipped L-foot part 600, and attracting the L-foot part 600 to the inner wall of the part slot 4021 by magnetic attraction. When the height of the component slot 4021 is greater than the thickness of the L-shaped component 600, if the second push rod 403 pushes the L-shaped component 600 into the component slot 4021 and the flip seat 402 rotates 90°, the L-shaped component 600 may slide or deflect. At this time, through the magnetic attraction of the limiter 409, the L-shaped component 600 can be pressed against the inner wall of the component slot 4021, thereby achieving "alignment". This makes it convenient for the first positioner 407 to position the horizontal position of the L-shaped component 600 without having to reposition / calculate the deflection angle of the L-shaped component 600. This ensures that the L-shaped component 600 maintains a stable posture on the flip seat 402, and guarantees the positioning accuracy of the subsequent patching device 300 when applying the waterproof pad. Furthermore, in practical applications, the horizontal adjustability of the limiter 409 allows the equipment to adapt to L-shaped parts 600 of different sizes and specifications, enhancing the equipment's versatility and flexibility. The application of magnetic attraction ensures a tight fit between the L-shaped part 600 and the inner wall of the part slot 4021, while avoiding damage to the part that may be caused by mechanical clamping, thereby improving the overall assembly quality. Specifically, the limiter 409 can adopt an electromagnet structure. By adjusting the magnetic force of the electromagnet, the attraction force can be ensured while avoiding excessive compression of the L-shaped part 600. During actual installation, the limiter 409 is installed on the mounting base 408 via a threaded connection or a slide rail mechanism. The operator can quickly adjust the horizontal position of the limiter 409 according to the thickness specifications of the L-shaped part 600 or production requirements, maintaining a 2-5mm gap between its end and the surface of the flipped L-shaped part 600, achieving magnetic positioning without interfering with part transportation.

[0042] The aforementioned flip base 402 and the third push rod 404 are mounted on the same base 410. The base 410 is provided with a rotating shaft 4101 for driving the flip base 402. The rotating shaft 4101 can be driven by a motor inside the base 410. The rotating shaft 4101 and the third push rod 404 are arranged vertically parallel to each other.

[0043] See Figure 4 The gasket transport device 100 of the present invention is shown: The aforementioned gasket transport device 100 includes a mounting platform 101, a damping tray 102, a peeling block 103, a third belt conveyor 104, a pressure roller 105, and a second stepper controller 106. The damping tray 102 is located at one end of the side of the mounting platform 101 and is used to wind the release paper 800. The adhesive side of the waterproof pad 700 is adhered to the release paper 800. A certain gap is reserved between adjacent waterproof pads 700 to avoid complete adhesion. The pad-attaching device 300 can vacuum-pick up the non-adhesive side of the waterproof pad 700 and directly attach the waterproof pad 700 downwards to the L-shaped part 600 that has been rotated 90° during its up-and-down movement. The peeling block 103... The third belt conveyor 104 is located on the side of the mounting platform 101 and below the damping disc 102 and the peeling block 103. At least one pressure roller 105 is installed close to the top of its belt and is rotatably mounted on the side of the mounting platform 101. The second step controller 106 is located between the damping disc 102 and the peeling block 103 and is used to detect the gap between the waterproof pads 700 and control the third belt conveyor 104. The release paper 800 on the damping disc 102 passes over the second step controller 106 and the peeling block 103 in sequence and is wound back between the pressure roller 105 and the third belt conveyor 104. Thus, the pad transport device 100 can convey the waterproof pads 700 one by one, and when the waterproof pads 700 above the peeling block 103 are picked up by the patching device 300, the release paper 800 can continue to move forward and return to the space between the pressure roller 105 and the third belt conveyor 104, thereby peeling the release paper 800 from the waterproof pads 700.

[0044] Furthermore, the aforementioned pad transport device 100 also includes a second positioner 107 disposed above the peeling block 103. The second positioner 107 is used to detect the position of the waterproof pad 700 on the peeling block 103 and send the position information to the patching device 300 so that the patching device 300 can position the waterproof pad 700 for precise pick-up. Specifically, similar to the first positioner 407, the second positioner 107 can also be a visual inspection device such as a CCD camera.

[0045] See Figure 5 The figure shows the parts transport device 200 of the present invention. As can be seen from the figure, the longer ends of the L-shaped parts 600 are attached to the top of the first belt conveyor 201, and the shorter ends are located on the rear side of the conveying direction, so that the longer ends of the L-shaped parts 600 can be pushed into the parts slot 4021 by the second push rod 403 in the subsequent process, ensuring the normal operation of the automatic bonding process. In addition, the L-shaped parts 600 are arranged at equal intervals above the first belt conveyor 201. This arrangement can be achieved by manual placement or placement by a robotic arm.

[0046] See Figure 6 The patch device 300 of the present invention is shown: The patching device 300 includes a robotic arm 301 with a two-stage horizontal swing function, and a vacuum chuck 302 disposed at the movable end of the robotic arm 301.

[0047] See Figure 13 The feeding device 500 of the present invention is shown: The aforementioned unloading device 500 includes a limiting member 502, a thickness detector 503, and a fifth push rod 504. The limiting member 502 is oscillatingly or vertically mounted above the second conveyor belt 501 to controllably prevent the L-shaped part 600 from advancing. The thickness detector 503 is vertically mounted above the second conveyor belt 501 and located to the side of the limiting member 502 to detect the thickness of the L-shaped part 600 blocked by the limiting member 502, specifically the thickness of the shorter end, to determine whether the L-shaped part has been fitted with a waterproof pad 700. The fifth push rod 504 is located on one side of the end of the second conveyor belt 501 and diverts the L-shaped parts 600 based on the detection result of the thickness detector 503. Thus, when the L-shaped part 600 is conveyed to the second conveyor belt 501, the unloading device 500 performs a "quality inspection," specifically checking whether the shorter end of the L-shaped part 600 is fitted with a waterproof pad 700, and then separating qualified and unqualified products. Specifically, both the limiting component 502 and the thickness detector 503 can be driven by devices such as cylinders or hydraulic cylinders to lift and lower.

[0048] Furthermore, the aforementioned feeding device 500 also includes a diversion guide rail 505, which is located on the other side of the end of the second belt conveyor 501 and is opposite to the fifth push rod 504. Thus, the fifth push rod 504 can push products that need to be diverted (e.g., defective products) to the diversion guide rail 505 for transport to a different destination than products that do not need to be diverted (qualified products).

[0049] Meanwhile, to ensure that the longer end of the L-shaped part 600 pushed out from the tilting seat 402 is attached to the upper surface of the second conveyor belt 501 for easy detection of the thickness of its shorter end, an inclined push plate 4061 is provided at the output end of the fourth push rod 406. The lower end of the inclined push plate 4061 is away from the fourth push rod 406. When the L-shaped part 600 is about to be completely pushed out of the tilting seat 402, the inclined push plate 4061 moves towards the lower end of the L-shaped part 600 under the drive of the fourth push rod 406 and abuts against the lower end of the L-shaped part 600, causing its upper end to tend to lean backward. Then, after the L-shaped part 600 is completely separated from the tilting seat 402, it is no longer limited by the tilting seat 402, and its upper end will naturally lean backward. That is, the shorter end of the L-shaped part 600 will lean backward until its longer end is attached to the upper surface of the inclined push plate 4061 and is pushed onto the second conveyor belt 501.

[0050] In this embodiment, along the length of each device, the first belt conveyor 201, the first transfer platform 401, the second transfer platform 405, the second belt conveyor 501, and the third belt conveyor 104 are all parallel to each other, and the first belt conveyor 201, the first transfer platform 401, and the second transfer platform 405 are arranged side by side, while the second belt conveyor 501 and the second transfer platform 405 are arranged along the same straight line, making the spatial layout of the entire equipment more compact and the footprint smaller.

[0051] In this embodiment, both the first step controller 202 and the second step controller 106 can be photoelectric sensors. Their function is to detect the gap between adjacent L-pin parts 600 / waterproof pads 700 through photoelectric signals, thereby determining whether the corresponding device has "moved forward one L-pin part 600 / waterproof pad 700". Then, through the preset program logic, the corresponding control command is issued. The control command is converted into current and drives the motor of the belt conveyor to work. Finally, the motor is precisely controlled to rotate at a preset angle and speed, so that the corresponding device can move the L-pin part 600 / waterproof pad 700 in a step-by-step manner at a preset frequency and speed.

[0052] In this embodiment, each of the above push rods (except the fourth push rod 406) can be equipped with a push plate at its output end so that it can have a larger contact area with the part and ensure that the action of pushing the L-foot part 600 to the corresponding position can be stably performed.

[0053] The workflow of this invention is as follows: (I) Parts transportation operation L-shaped parts 600 are arranged at equal intervals on the first belt conveyor 201 with the longer end horizontally attached and the shorter end vertically upward. The stepping conveyor 201 is controlled by the first stepping controller 202. When the L-shaped parts 600 reach the end of the first belt conveyor 201, the first push rod 203 pushes them one by one into the first transfer table 401. In the initial state, the part slot 4021 of the flip base 402 is horizontally oriented towards the second push rod 403. The second push rod 403 pushes the L-foot part 600 on the first adapter 401 into the part slot 4021 of the flip base 402. Then, the flip base 402 is rotated 90° under the drive of the rotating shaft 4101, so that the part slot 4021 faces upward, and the L-foot part 600 is rotated 90°. At this time, the shorter end of the L-foot part 600 is rotated to a horizontal state, and the surface of the pre-attached waterproof pad 700 is facing upward. The limiter 409 uses magnetic attraction to press the L-foot part 600 against the inner wall of the part slot 4021 to ensure stable posture. Then, the first positioner 407 detects the position information of the L-foot part 600 and sends it to the patching device 300.

[0054] At the same time, the damping disc 102 releases the release paper 800 with the waterproof pad 700 attached, and the second step controller 106 controls the stepping conveyor of the third belt conveyor 104; each step of the third belt conveyor 104 drives each waterproof pad on the release paper 800 to move forward one step; at each step, the second positioner 107 detects the specific position of the waterproof pad 700 above the peeling block 103 and sends it to the patching device 300.

[0055] (II) Fitting action Based on the position information of the waterproof pad 700 on the peeling block 103 and the L-shaped part 600 on the flipping seat 402, the robotic arm 301 of the patching device 300 drives its vacuum suction cup 302 to perform a combination of horizontal and vertical movements between the two position information, so as to pick up the waterproof pad 700 and attach it to the L-shaped part 600, specifically attaching it to the back of the shorter end of the L-shaped part 600 (the preset bonding surface).

[0056] (III) Quality Inspection After bonding is completed, the third push rod 404 inserts into the push rod through hole 4022 of the flip seat 402, pushing the bonded L-shaped part 600 out of the part slot 4021 and causing it to fall into the second transfer table 405; the fourth push rod 406 pushes the L-shaped part 600 on the second transfer table 405 into the second conveyor belt 501 through the inclined push plate 4061. At this time, the L-shaped part 600 returns to the posture of "the longer end is horizontal and the shorter end is vertically upward", and is conveyed forward by the second conveyor belt 501; the limiting member 502 continuously cycles through the "blocking" and "releasing" states: In the blocking state, when the L-foot part 600 moves to the limit member 502, the limit member 502 prevents it from moving forward. Then the thickness detector 503 descends and detects the thickness of the shorter end of the L-foot part 600 (to determine whether a waterproof pad 700 is attached), and feeds the detection result back to the control system to determine the action of the fifth push rod 504. After that, the limit member 502 switches to the "release" state. Then, the second conveyor belt 501 continues to transport the L-shaped part 600 forward until it moves to the end of the second conveyor belt 501. The fifth push rod 504 then diverts the products according to the test results: qualified products with waterproof pads 700 attached continue to be transported by the second conveyor belt 501 to the next process; while unqualified products are pushed by the fifth push rod 504 to the diversion guide rail 505 and transported to the designated area.

[0057] In summary, this invention innovatively achieves integrated automated assembly and quality inspection between the L-shaped foot component 600 and the waterproof pad 700 with adhesive backing, specifically designed for metal roof photovoltaic brackets. This breakthrough solves the efficiency bottlenecks and quality fluctuations inherent in traditional manual assembly, significantly improving production efficiency and the automation level of the photovoltaic bracket component industry. Specifically, it achieves the following technical effects: (1) Precision delivery control L-shaped foot component 600 and waterproof pad 700 are transported synchronously through independent transport devices equipped with stepper controllers. The conveying speed can be precisely adjusted according to the assembly rhythm to ensure efficient matching between material supply and assembly process.

[0058] (2) Oriented flipping and fixing In view of the structural characteristics of the L-shaped part 600, a dedicated part flipping device 400 is set up to achieve directional flipping. At the same time, the limiter 409 is used to accurately fix the L-shaped part 600 on the assembly station (flipping seat 402), providing a stable reference for subsequent bonding.

[0059] (3) Automated adsorption assembly Two positioners control the patching device 300 to accurately capture the positions of the L-shaped part 600 and the waterproof pad 700, and control the vacuum suction cup 302 of the patching device 300 to accurately pick up the waterproof pad 700. Then, based on the positioning information, the waterproof pad 700 and the L-shaped part 600 are automatically bonded and assembled, which can ensure the accuracy of the bonding position.

[0060] (4) Quality screening The assembly process is equipped with a quality inspection function at the back end. The thickness detector 503 detects the thickness of the shorter end of the L-shaped part 600, which automatically identifies unqualified products and triggers the rejection mechanism to remove unqualified products from the production flow, thus realizing a fully automated closed loop of "assembly-inspection-screening".
