Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to an integrated machine for punching and riveting frames. Background Technology

[0002] Photovoltaic modules are devices used to convert solar energy into electrical energy, and are generally assembled from photovoltaic panels and frames. Each side of a photovoltaic panel has a frame, and adjacent frames need to be connected together using L-shaped corner brackets. The frames are generally cut from long strips of profile with identical cross-sectional structures. When used for frames, holes need to be punched in the profile for fixing or threading wires; and riveting is also required to secure the corner brackets. Therefore, to complete the assembly, the frames need to be punched and riveted, which is often done on a specialized machine.

[0003] Chinese patent CN222536065U discloses a device for punching and pressing points on solar panel frames, including a horizontal pneumatic punch press for punching and a servo pressing point device for pressing and riveting the frame and corner brackets together. The frame is positioned with the punched edge at the bottom in the horizontal pneumatic punch press and with the punched edge at the top in the servo pressing point device, requiring the frame to rotate 180° during movement. In this device, the translation of the frame is accomplished by a PPU robot, which is responsible for transferring the frame between multiple workstations. The servo pressing point device requires an additional 180° tilting cylinder for tilting, necessitating high precision in coordination with the PPU robot, posing a significant risk of drop and incurring high costs.

[0004] Therefore, it is necessary to improve the equipment structure to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a frame punching and riveting integrated machine that can continuously complete the punching and riveting work of the frame, with low control difficulty and high work efficiency.

[0007] Front-end conveyor line;

[0008] A horizontal punching device is located on the X-direction outlet side of the feed conveyor line;

[0009] The rear conveyor line is located on the X-direction outlet side of the horizontal punching device;

[0010] A conveying device is located above the front conveyor line and the horizontal punching device and is used to convey the frame from the front conveyor line to the horizontal punching device.

[0011] Two riveting devices are respectively located on both sides of the Y-direction of the rear conveyor line;

[0012] A 180° flipping device is used to remove the frame from the horizontal punching device and then flip it 180° to place it on the rear conveyor line.

[0013] Specifically, both the front conveyor line and the rear conveyor line include two conveyor belts arranged along the X direction. The conveyor belts are provided with partition protrusions at intervals along their outer periphery, and the recessed space between adjacent partition protrusions can only accommodate one frame to enter.

[0014] Specifically, the 180° flipping device includes a rotating reference platform, a telescopic drive, a sliding platform, and a flipping assembly. The telescopic drive drives the sliding platform to move relative to the rotating reference platform along the X direction. The flipping assembly includes a Y-axis rotating shaft rotatably mounted on the sliding platform, a gear located in the middle of the Y-axis rotating shaft, and two flipping pneumatic grippers located at both ends of the Y-axis rotating shaft. The rotating reference platform is provided with an X-axis rack that cooperates with the gear.

[0015] Furthermore, the horizontal punching device includes a punching station and a transfer station arranged forward and backward along the X direction. The punching station includes multiple horizontal punching dies arranged side by side along the Y direction. The transfer station includes two transfer brackets. The handling device includes a PPU robot and two pairs of clamping mechanisms driven by the PPU robot. One pair of clamping mechanisms moves the frame from the exit of the front conveyor line to the punching station, and the other pair of clamping mechanisms moves the frame from the punching station to the transfer station. A 180° flipping device picks up the frame from the transfer station.

[0016] Specifically, the riveting device includes several first Y-axis slide rails, a riveting platform that slides along the first Y-axis slide rails, a Y-axis drive member that drives the riveting platform to move in the Y-axis direction, a push block assembly located on the outer Y-axis side of the riveting platform, a riveting pneumatic gripper located on the inner Y-axis side of the riveting platform, a clamping assembly and a riveting assembly located above the riveting platform; the push block assembly includes a push block cylinder and a push block driven by the push block cylinder to move in the Y-axis direction; the riveting pneumatic gripper clamps the ends of the frame from both sides in the X-axis direction; the clamping assembly includes a clamping cylinder and a pressure rod driven by the clamping cylinder to move in the Z-axis direction, the pressure rod being located above the riveting pneumatic gripper; the riveting assembly includes a riveting cylinder and a pressure block driven by the riveting cylinder to move in the Z-axis direction, the pressure block being located on the outer Y-axis side of the pressure rod, the bottom of the pressure block having several protrusions; the riveting platform has a riveting support block located below the pressure block.

[0017] Furthermore, the upper surface of the push block is provided with a plurality of grooves along the Y direction, the grooves matching the positions of the protrusions.

[0018] Furthermore, each riveting device is provided with a corner code feeding mechanism on one side, the outlet of which extends along the X direction and to the front of the push block.

[0019] Furthermore, the riveting device also includes two positioning sensors for detecting when the frame reaches the riveting station.

[0020] Furthermore, a detection device is provided at the end of the rear conveyor line, and a defective conveyor line is also provided below the X-direction outlet of the rear conveyor line. The width of the defective conveyor line is smaller than the width of the two conveyor belts of the rear conveyor line. A drive shaft is provided at the outlet of the rear conveyor line to drive the two conveyor belts synchronously. Several swing blocks are rotatably mounted on the drive shaft. The swing blocks are driven to swing by a swing cylinder located below the conveying surface of the rear conveyor line. When the detection device detects the frame, the swing blocks swing down, causing the frame to fall onto the defective conveyor line.

[0021] Furthermore, the detection device is a length detection device, including two detection clamping assemblies and two detection side pushing mechanisms. The detection clamping assembly includes a detection lifting cylinder, a detection gripper, and a second Y-axis slide rail. The detection lifting cylinder is adjustablely positioned on the second Y-axis slide rail. The detection lifting cylinder drives the detection gripper to move up and down along the Z-axis. The detection gripper clamps the ends of the frame from both sides in the X-axis. The detection side pushing mechanism is connected to the riveting platform.

[0043] 200-border. Detailed Implementation

[0044] The present invention will be further described in detail below with reference to specific embodiments.

[0045] Example 1:

[0046] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, this utility model discloses a frame punching and riveting integrated machine 100, comprising a front conveyor line 1a, a horizontal punching device 2, a rear conveyor line 1b, a handling device 3, a 180° flipping device 4, and two riveting devices 5. The front conveyor line 1a, the horizontal punching device 2, the 180° flipping device 4, and the rear conveyor line 1b are arranged sequentially along the X-direction. The handling device 3 is located above the front conveyor line 1a and the horizontal punching device 2 and is used to transport the frame 200 from the front conveyor line 3 to the horizontal punching device 2. The two riveting devices 5 are respectively located on both sides of the rear conveyor line 1b along the Y-direction. The 180° flipping device 4 is used to remove the frame 200 from the horizontal punching device 2 and then flip it 180° to place it on the rear conveyor line 1b. The X and Y directions are both in the horizontal plane and perpendicular to each other, while the Z-direction is vertical.

[0047] The horizontal punching device 2 is located on the X-direction outlet side of the feeding conveyor line 1, and the rear conveyor line 1b is located on the X-direction outlet side of the horizontal punching device 2. Therefore, the entire frame 200 passes through the frame punching and riveting integrated machine 100 along the X-direction. The feeding conveyor line 1 conveys the cut frame 200 backwards, and the conveying device 3 transfers the frame 200 from the end of the feeding conveyor line 1 to the horizontal punching device 2, thereby completing the punching. During punching, the punched edge of the frame 200 is in a vertical position, while the riveting edge of the frame 200 is located below. However, the riveting device 5 generally rivets from top to bottom, so the frame 200 needs to have its riveting edge flipped upwards. Therefore, a 180° flipping device 4 is used to move the frame 200 out of the punching machine and flip it simultaneously, so that when both ends of the frame 200 reach the riveting device 5, the riveting edge can be facing upwards. This frame punching and riveting integrated machine 100 can continuously complete the punching and riveting work of frame 200, with low control difficulty and high work efficiency.

[0048] like Figure 1 and Figure 4 As shown, both the front conveyor line 1a and the rear conveyor line 1b include two conveyor belts 11 arranged along the X direction. The conveyor belts 11 are provided with partition protrusions 111 at intervals along their outer periphery. The recessed space between adjacent partition protrusions 111 can only accommodate one frame 200.

[0049] Each frame 200 is supported by two conveyor belts 11 on both sides along its length. The partition protrusions 111 separate the front and rear frames 200, which can prevent the frames 200 from colliding with each other and also provide sufficient space between the front and rear frames 200 for the handling device 3 to clamp.

[0050] like Figure 2 , Figure 8 and Figure 9 As shown, the 180° flipping device 4 includes a rotating reference platform 41, a telescopic drive member 42, a sliding platform 43, and a flipping assembly 44. The telescopic drive member 42 drives the sliding platform 43 to move relative to the rotating reference platform 41 in the X direction. The flipping assembly 44 includes a Y-axis rotating shaft 441 rotatably mounted on the sliding platform 43, a gear 442 located in the middle of the Y-axis rotating shaft 441, and two flipping pneumatic grippers 443 located at both ends of the Y-axis rotating shaft 441. The rotating reference platform 41 is provided with an X-axis rack 411 that cooperates with the gear 442.

[0051] The relative position of the axis of the Y-axis rotating shaft 441 and the sliding platform 43 remains unchanged. During the movement of the sliding platform 43 along the X-axis driven by the telescopic drive 42, the gear 442 and the X-axis rack 411 continuously mesh, causing the tilting pneumatic gripper 443 to move both horizontally and vertically. Both tilting pneumatic grippers 443 can open 180°, thus clamping both ends of the frame 200 when rotated to the material-picking position. Subsequently, the telescopic drive 42 drives the sliding platform 43 to move along the positive X-axis, causing the tilting pneumatic grippers 443 to tilt the frame 200 180°. When the frame 200 lands on the downstream conveyor line 1b, the tilting pneumatic grippers 443 release the frame 200, allowing it to continue being conveyed. This rapid tilting action improves the overall efficiency of the equipment. The movement path of the tilting pneumatic grippers 443 must avoid the horizontal punching device 2 and the downstream conveyor line 1b.

[0052] like Figure 2 As shown, the horizontal punching device 2 includes a punching station and a transfer station arranged forward and backward along the X direction. The punching station includes multiple horizontal punching dies 21 arranged side by side in the Y direction. The transfer station includes two transfer brackets 22. The conveying device 3 includes a PPU robot 31 and two pairs of clamping mechanisms 32 driven by the PPU robot 31. One pair of clamping mechanisms 32 moves the frame 200 from the exit of the front conveyor line 1a to the punching station, and the other pair of clamping mechanisms 32 moves the frame 200 from the punching station to the transfer station. The 180° flipping device 4 grabs the frame 200 from the transfer station.

[0053] The punching direction of the horizontal punching device 2 is X-axis, and the punching station is composed of many horizontal punching dies 21 arranged side by side along the Y-axis. The horizontal punching dies 21 will occupy the lower position of the frame 200, so they must be moved to the transfer station first to make the vertical direction of the frame 200 unobstructed, so that the pneumatic gripper 443 can easily clamp the frame 200.

[0054] like Figure 3 and Figure 4 As shown, the riveting device 5 includes several first Y-axis slide rails 51, a riveting platform 52 that slides along the first Y-axis slide rails 51, a Y-axis drive member (not exposed) that drives the riveting platform 52 to move along the Y-axis, a push block assembly 53 located on the outer Y-axis side of the riveting platform 52, a riveting pneumatic gripper 54 located on the inner Y-axis side of the riveting platform 52, a clamping assembly 55 located above the riveting platform 52, and a riveting assembly 56; the push block assembly 53 includes a push block cylinder 531 and a push block 532 driven by the push block cylinder 531 to move along the Y-axis, and the upper surface of the push block 532 is provided with several grooves 5321 along the Y-axis; riveting Pneumatic grippers 54 clamp the ends of the frame 200 from both sides in the X direction; the clamping assembly 55 includes a clamping cylinder 551 and a pressure rod 552 driven by the clamping cylinder 551 to move in the Z direction, the pressure rod 552 being located above the pneumatic grippers 54; the riveting assembly 56 includes a riveting cylinder 561 and a pressure block 562 driven by the riveting cylinder 561 to move in the Z direction, the pressure block 562 being located outside the pressure rod 552 in the Y direction, the bottom of the pressure block 562 having several protrusions 5621, and grooves 5321 matching the positions of the protrusions 5621; the riveting platform 52 has a riveting support block 521 located below the pressure block 562. The riveting device 5 also includes two positioning sensors 57 for detecting when the frame 200 reaches the riveting position.

[0055] The riveting area of ​​the frame 200 is at both ends, corresponding to the processing positions of the protrusions 5621. Therefore, two riveting devices 5 are used, and the two riveting devices 5 are basically symmetrical along a certain XZ plane. There are two riveting pneumatic grippers 54, which are used to clamp the two ends of the frame 200 respectively. Before the frame 200 reaches the riveting station, the opening angle of the riveting pneumatic grippers 54 will be opened by 180°, so as not to interfere with the translation of the frame 200. When the frame 200 moves along the subsequent conveyor line 1b, its length direction cannot be strictly along the Y direction. Therefore, after the frame 200 is in place, the riveting pneumatic grippers 54 will clamp it, so that the length direction of the frame 200 is first along the Y direction, and its two ends will be directly opposite the two push blocks 532 respectively. The frame 200 has a square tube-shaped part, and the push blocks 532 need to be inserted into the inside of the square box to serve as the reverse support of the riveting area. The riveting support block 521 supports the back of the riveting area from below, while the pressure rod 552 presses down on the material adjacent to the riveting area from above, ensuring the stability of the frame 200 during the riveting process. The riveting cylinder 561 drives the pressure block 562 to press down, and the riveting is completed by the protrusions 5621 on the pressure block 562. After the riveting is completed, part of the material of the frame 200 will be recessed into the groove 5321. However, because the groove 5321 extends along the Y direction, the push block 532 will not get stuck when it exits the square frame structure. In this embodiment, the positioning sensor 57 is located inside the riveting pneumatic gripper 54. In practical applications, the two positioning sensors 57 only need to be able to sense that both ends of the frame 200 have reached the riveting position without interfering with the movement of the frame 200. Their positions can be above or below, and the sensing direction can be upward, downward, or diagonal.

[0056] Example 2:

[0057] like Figure 5 As shown, the difference from Embodiment 1 is that each riveting device 5 is also provided with a corner code feeding mechanism 6 on one side, and the outlet of the corner code feeding mechanism 6 extends along the X direction to the front of the push block 532.

[0058] Some of the frame 200 needs to have corner brackets pre-installed, so the corner bracket feeding mechanism 6 is used to provide corner brackets to the riveting device 5. The push block 532 is used to insert the corner brackets into the side of the frame 200 along the Y direction, without inserting them into the frame 200, so there is no need for a groove 5321.

[0059] Example 3:

[0060] like Figure 1 , Figure 5 and Figure 7As shown, the difference from Embodiment 1 is that: a detection device 8 is provided at the end of the rear conveyor line 1b, and a defective conveyor line 7 is also provided below the X-direction outlet of the rear conveyor line 1b. The width of the defective conveyor line 7 is smaller than the width of the two conveyor belts 11 of the rear conveyor line 1b. A drive shaft 12 is provided at the outlet of the rear conveyor line 1b to drive the two conveyor belts 11 synchronously. Several swing blocks 13 are rotatably mounted on the drive shaft 12. The swing blocks 13 are driven to swing by a swing cylinder 14 located below the conveying surface of the rear conveyor line 1b. When the detection device 8 detects that the frame 200 is defective, the swing blocks 13 swing down, causing the frame 200 to fall onto the defective conveyor line 7.

[0061] At the same height as the exit of the rear conveyor line 1b, there are usually other conveying devices, and the defective conveyor line 7 is actually located below this conveying device. After the riveting operation is completed on the frame 200, it is necessary to check whether the quality of the riveted product is qualified. If the inspection result is qualified, the swing block 13 remains in an upward swinging state, and the frame 200 enters the conveyor device, thus entering the next workstation; if it is found to be unqualified, the swing cylinder 14 will drive the swing block 13 to swing downward, so that the frame 200 moves below the exit and falls onto the defective conveyor line 7 for centralized processing.

[0062] like Figure 7 As shown, the detection device 8 is a length detection device, including two detection clamping assemblies 81 and two detection side pushing mechanisms 82. The detection clamping assembly 81 includes a detection lifting cylinder 811, a detection gripper 812, and a second Y-axis slide rail 813. The detection lifting cylinder 811 is adjustablely positioned on the second Y-axis slide rail 813. The detection lifting cylinder 811 drives the detection gripper 812 to move up and down along the Z-axis. The detection gripper 812 clamps the ends of the frame 200 from both sides in the X-axis direction. The detection side pushing mechanism 82 is connected to the riveting platform 52. The detection side pushing mechanism 82 detects the length of the frame 200 by contacting the two end faces of the frame 200.

[0063] If the width of the frame 200 itself is problematic or the corner bracket protrudes from the end of the frame 200, the detected length of the frame 200 will be abnormal. The detection process involves the downstream conveyor line 1b moving the frame 200 to the detection station (i.e., above the detection clamping assembly 81). The detection lifting cylinder 811 drives the detection gripper 812 to rise, clamping both ends of the frame 200 with the two detection grippers 812, thus determining its length direction along the Y direction. Subsequently, two detection side-pushing mechanisms 82 move closer together to detect the real-time length of the frame 200. If this length is within the acceptable range, the frame 200 is discharged; otherwise, it is sent to the defective conveyor line 7 for collection. Because the distance of the riveting platform 52 can accommodate various frame 200 lengths, the detection side-pushing mechanism 82 is preferably located on the riveting platform 52 to allow it to adapt to various frame 200 lengths.

[0064] The working process of this frame punching and riveting integrated machine 100 is as follows:

[0065] The frame 200 to be processed is conveyed to the picking area of ​​the handling device 3 via the front conveyor line 1a. The PPU robot 31 drives the first pair of clamping mechanisms 32 to move the frame 200 onto the horizontal punching die 21, and then the horizontal punching die 21 completes the punching. The second pair of clamping mechanisms 32 on the PPU robot 31 transfers the punched frame 200 from above the horizontal punching die 21 to the transfer bracket 22. At this time, the flipping pneumatic gripper 443 is waiting behind the transfer bracket 22. Once the frame 200 is placed on the transfer bracket 22, the flipping pneumatic gripper 443 immediately clamps the frame. At both ends of 200, after the second pair of clamping mechanisms 32 have disengaged, under the action of the telescopic drive component 42, the flipping pneumatic gripper 443 moves along the X direction while simultaneously flipping the frame 200 180°, so that the frame 200 lands at the inlet of the rear conveyor line 1b and the riveting area of ​​the frame 200 is flipped upwards; the rear conveyor line 1b continues to move the frame 200 to the riveting station, and when the two positioning sensors 57 simultaneously sense the frame 200, the rear conveyor line 1b pauses its conveying, and the two riveting platforms 52 move inwards in the Y direction. The riveting pneumatic gripper 54 and the pressure rod 552 together press the frame 200... The frame 200 is clamped; for the frame 200 without corner brackets, the push block 532 is inserted into the side of the frame 200, and then the pressure block 562 presses down, the protrusion 5621 presses out a recessed structure on the frame 200, and then the riveting device 5 resets; for the frame 200 with corner brackets, the corner bracket feeding mechanism 6 supplies the corner brackets to the front of the push block 532, and then the push block 532 pushes the corner brackets into the side of the frame 200, and then the pressure block 562 presses down, the material of the frame 200 that is dented by the protrusion 5621 will hold the corner brackets in place; the frame 200 after riveting is completed continues to be conveyed by the downstream conveyor line 1b to the detection device 8. At the detection point, the lifting cylinder 811 drives the detection gripper 812 to rise, thereby clamping the frame 200. Then, the two detection side push mechanisms 82 move closer to each other until they press against the two end faces of the frame 200, and the length of the frame 200 is measured at this time. Then, the detection device 8 resets. If the length of the frame 200 is not within the acceptable range, when the frame 200 continues to be conveyed on the rear conveyor line 1b, the swing cylinder 14 drives the swing block 13 to swing down, and the frame 200 flows into the defective conveyor line 7. If the length of the frame 200 is within the acceptable range, the swing block 13 swings up, and the frame 200 flows into the next workstation.

[0066] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
