Description

Technical Field

[0001] This invention belongs to the field of photovoltaic frame processing technology, and in particular relates to a feeding system based on a photovoltaic frame rotary disc spraying line and its usage method. Background Technology

[0002] To improve the various performance characteristics of photovoltaic frames, such as corrosion resistance, a coating needs to be sprayed on the frame. In order to improve the coating coverage, the coating is sprayed after the profile is processed (end cuts, installation openings on the C-side, etc.). The profile can be sprayed in all directions through a rotary disc spraying line.

[0003] Modern rotary coating lines use a rotating suspension line to carry the profile through the coating chamber. The coating chamber is equipped with a rotary coating head. The rotating suspension line in the coating line drives the profile to rotate around the rotary coating head, which promotes uniform and comprehensive coating. A large number of hanging points are arranged on the rotating suspension line for lifting the profile.

[0004] Due to the special structure of the profile, it can only be mounted on the mounting holes on the C-side of the profile. However, since the diameter of the mounting holes is relatively small, it is not conducive to automated positioning and mounting. If the material is loaded manually, the mounting holes at the top of the profile are not easy to observe and position because the rotating suspension line is at a certain height from the ground. Therefore, it is not conducive to the operation of the staff, wasting manpower and resources and affecting efficiency.

[0005] However, when using robots to grab or pick up profiles for loading, the small difference in diameter between the profile mounting holes and the lifting hooks means that even a small positional deviation during the grabbing or moving process can cause problems with the inability to pierce and position the profiles, affecting normal loading. In addition, using robots requires moving the profiles a considerable distance, which affects work efficiency and accuracy. Summary of the Invention

[0006] The purpose of this invention is to provide a feeding system based on a photovoltaic frame rotary disc spraying line. Through the design of the hanging device, a certain number of profiles can be temporarily stored, and the precise position of the profiles can be ensured. The system can also automatically hang the profiles on the rotary suspension line of the spraying line. Compared with manual feeding, it greatly improves work efficiency. Compared with direct feeding by robots, it improves positional stability and feeding accuracy, avoids the situation where the installation opening diameter is too small and it is difficult to position and pass through, and improves the efficiency and automation of photovoltaic frame production and processing.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention is a feeding system based on a photovoltaic frame rotary disc spraying line, comprising two hanging devices, a robot, and several suspension point mechanisms evenly connected to a rotary suspension line on the spraying line at intervals; The hanging device includes a column, a lifting slide, an adsorption base, and a positioning frame; A back plate is fixed to the top of the column, the lifting slide is connected to the front side of the back plate through a horizontal telescopic mechanism, and the adsorption seat is fixed to the front side of the sliding end of the lifting slide. The front side of the adsorption seat is provided with several partitions, and a profile groove is formed between two adjacent partitions. A strip-shaped through groove is provided in the profile groove. An electromagnet is fixed in the several through grooves. The front side of the electromagnet is flush with the front side of the adsorption seat. The positioning frame includes a mounting beam, on which a plurality of proximity sensors are linearly arranged. The mounting beam is fixed to the area above the rear side of the adsorption seat by a plurality of L-shaped brackets, and the plurality of proximity sensors are respectively positioned opposite to a plurality of profile grooves. The two hanging devices are arranged side by side directly below the loading area of ​​the rotary suspension line on the spraying line. The robot's forearm is connected to a profile adsorption rack, and the robot is located in the middle of the front side of the two hanging devices. The lifting mechanism consists of an upper lifting rod, a connecting block, and a lower lifting hook connected sequentially from top to bottom. The top of the upper lifting rod is connected to the rotary suspension line on the spraying line. Both the upper lifting rod and the lower lifting hook are rigid rods.

[0008] Furthermore, the robot is a five-axis robot, and the profile adsorption frame includes a beam body. Several electromagnetic adsorption points or vacuum adsorption points are linearly arranged on the beam body, and the circuit or air passage of the adsorption points is set in the beam body.

[0009] Furthermore, an expansion frame is fixed to the rear side of the adsorption seat, and the mounting beam is positioned directly above the expansion frame.

[0010] Furthermore, the front side of the lifting slide is provided with a lead screw mechanism and a set of slide rails, the rear side of the expansion frame is fixed on the sliding end of the lead screw mechanism, and the rear side of the expansion frame is provided with a linear module that slides with the slide rails.

[0011] Furthermore, guide rods are fixed at the four corners of the rear side of the lifting slide, the guide rods penetrate the back plate and are slidably connected to the back plate, and the guide rods are provided with a limit at one end of the rear side of the back plate.

[0012] Furthermore, the horizontal telescopic mechanism is a hydraulic cylinder or a pneumatic cylinder, the horizontal telescopic mechanism is fixed to the rear side of the back plate, and the end of the telescopic rod of the horizontal telescopic mechanism passes through the back plate and is fixed to the rear side of the lifting slide.

[0013] Furthermore, the rear side of the electromagnet extends beyond the rear side of the adsorption seat and forms an outward protrusion. The rear side of the adsorption seat is linearly fixed with several fastening edges covering the outward protrusion, and the expansion frame is fixed on the several fastening edges and misaligned with the electromagnet.

[0014] Furthermore, the lower hook is composed of a vertical rod and a diagonal rod, and the vertical rod and the diagonal rod form an acute angle structure.

[0015] Furthermore, a drive mechanism is provided on the slewing suspension line, and an encoder is provided on the drive mechanism.

[0016] The present invention provides a method for using a feeding system based on a photovoltaic frame rotary coating line, comprising the following steps: The SS01 robot picks up the profiles at the end of the profile production line and moves them into a profile slot, ensuring that the C-side of the profile is in contact with the front side of the adsorption seat. The robot detects the profile through a proximity sensor above the profile slot and adjusts itself by moving up and down in the profile slot until the proximity sensor detects a hole in the profile, indicating that the position is in place. The robot then controls the electromagnet at the profile slot to adsorb and fasten the profile. The SS02 robot resets and grabs the next profile, filling the profile slots on the suction seat in sequence. Once the suction seat on one hanging device is full, the robot grabs the profile again to feed the other hanging device. SS03 Once the suction seat of the hanging device is full, the suction seat is raised to a set height by the lifting slide. The set height is the height of the hook end of the lower hook. The SS04 slewing suspension line travels a certain distance, causing a lifting point mechanism to align with the position of the first profile on the hanging device. This stops the slewing suspension line. During the stop time, the horizontal telescopic mechanism can be controlled to move the profile toward the lifting point mechanism. The profile can be moved up and down by the lifting slide. The combination of the horizontal telescopic mechanism and the lifting slide can be used to control the profile to move along a certain arc trajectory, allowing the profile to be hung on the lower hook. After hanging, the electromagnet corresponding to this profile can be controlled to stop attracting. After the first profile is mounted, continue to start the slewing suspension line to travel a certain distance until the next lifting point mechanism is aligned with the position of the second profile. Then, mount the second profile again using the same method as in SS04. Load all the profiles on this mounting device in the same way. After the first hanging device finishes loading, the second hanging device is ready and in the state of SS02. Control the first hanging device to reset and perform the operation of SS01. SS07. Install the profiles on the second mounting device sequentially according to the methods of SS04-SS05.

[0017] The present invention has the following beneficial effects: 1. This invention, through the design of the hanging device, can temporarily store a certain number of profiles and ensure the precise position of the profiles. It can also automatically hang the profiles on the rotary suspension line of the spraying line. Compared with manual feeding, it greatly improves work efficiency. Compared with direct feeding by robots, it improves positional stability and feeding accuracy, avoids the situation where the installation opening diameter is too small and it is difficult to position and pass through, and improves the efficiency and automation of photovoltaic frame production and processing.

[0018] 2. This invention designs two hanging devices capable of storing materials, one for working and one for standby, to achieve continuous production and processing. At the same time, the hanging devices are close to the lifting point mechanism, which is shorter than the direct loading by the robot, thus improving efficiency and stability.

[0019] 3. The present invention, through the design of rows of proximity sensors, can detect the mounting holes in the middle of the profile, thereby determining the position of the mounting holes at the top of the profile, so that the adsorption seat can adsorb the middle of the profile, thus improving the adsorption stability of the profile.

The top end of the upper lifting rod 301 is connected to the rotary suspension line on the spraying line. Both the upper lifting rod 301 and the lower lifting hook 303 are rigid rods.

[0025] The robot 2 is a five-axis robot, and the profile adsorption frame 201 includes a beam. Several electromagnetic adsorption points or vacuum adsorption points are linearly arranged on the beam, and the circuit or air passage of the adsorption points is set in the beam.

[0026] Among them, such as Figure 1-2 As shown, the adsorption seat 6 has a distance-expanding frame 8 fixed to its rear side, and the mounting beam 701 is positioned directly above the distance-expanding frame 8.

[0027] The lifting slide 5 is provided with a lead screw mechanism and a set of slide rails on its front side. The rear side of the extension frame 8 is fixed on the sliding end of the lead screw mechanism. The rear side of the extension frame 8 is provided with a linear module that slides with the slide rails.

[0028] Among them, such as Figure 1 As shown, guide rods 501 are fixed at the four corners of the rear side of the lifting slide 5. The guide rods 501 pass through the back plate 401 and are slidably connected to the back plate 401. The guide rods 501 are provided with a limit at one end of the rear side of the back plate 401.

[0033] The present invention provides a method for using a feeding system based on a photovoltaic frame rotary coating line, comprising the following steps: SS01 Robot 2 picks up the profile at the end of the profile production line and moves it into a profile slot, ensuring that the C-side of the profile is in contact with the front side of the adsorption seat 6. The profile is detected by the proximity sensor 702 above the profile slot. Robot 2 adjusts its position by moving up and down on the profile slot until the proximity sensor 702 detects a hole in the profile, indicating that the position is in place. Then, the electromagnet 603 at the profile slot is controlled to adsorb and fasten the profile. SS02 Robot 2 resets and grabs the next profile again, filling the profile slot on the adsorption seat 6 in sequence. When the adsorption seat 6 on one hanging device 1 is filled, Robot 2 grabs the profile again to feed the other hanging device 1. SS03 When the suction seat 6 of the hanging device 1 is full, the suction seat 6 is driven to rise to the set height by the lifting slide 5. The set height is the height of the hook end of the lower hook 303. When the SS04 slewing suspension line travels a certain distance, it drives a lifting point mechanism 3 to align with the position of the first profile on the hanging device 1, controlling the slewing suspension line to stop. During the stop time, the horizontal telescopic mechanism 402 can control the profile to move towards the lifting point mechanism 3. The lifting slide 5 controls the profile to move up and down. The combination of the horizontal telescopic mechanism 402 and the lifting slide 5 controls the profile to move along a certain arc trajectory, which can hang the profile on the lower hook 303. After hanging, the electromagnet 603 corresponding to this profile is controlled to stop attracting. After the first profile is mounted, continue to start the slewing suspension line to travel a certain distance until the next lifting point mechanism 3 is aligned with the second profile. Then, mount the second profile again using the same method as SS04. Load all the profiles on this mounting device 1 in the same way. After the first hanging device 1 has finished loading, the second hanging device 1 is ready and in the state of SS02. Control the reset of the first hanging device 1 to perform the operation of SS01. SS07. Install the profiles on the second mounting device 1 sequentially according to the methods of SS04-SS05.

[0034] By setting the encoder on the drive mechanism of the rotary suspension line, the travel distance of the rotary suspension line can be adjusted, thereby adjusting the movement distance of the suspension point mechanism 3. The movement of the suspension point mechanism 3 on the rotary suspension line can be controlled by programming. For example, if there are ten profiles on the suction seat 6 of the first hanging device 1, initially, one suspension point mechanism 3 aligns with the hole of the first profile on the suction seat 6. Then, with each subsequent travel of the rotary suspension line, the distance between two profiles is reduced sequentially (causing the next suspension point mechanism 3 to align with the hole of the profile on the suction seat 6). After nine such reductions, it indicates that the first hanging device... Once the profile on component device 1 is fully loaded, the profile on the second hanging device 1 is ready. Control the rotating suspension line to travel a distance L1, and set the distance L1 so that a lifting point mechanism 3 is aligned with the hole of the first profile on the second hanging device 1. Then, follow the same method to fully load the profile on the second hanging device 1. Once the profile on the first hanging device 1 is ready, control the line to travel a distance L2 again, and set the distance L2 so that a lifting point mechanism 3 is aligned with the hole of the first profile on the first hanging device 1 (this position is the initial position).
