Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a corner code feeding device and a photovoltaic corner code riveting equipment. 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 are joined together using L-shaped corner brackets. Figure 1 As shown, in a photovoltaic module product, the corner code 100 has a first insertion part 101 and a second insertion part 102 that are perpendicular to each other. The first insertion part 101 and the second insertion part 102 have similar structures and are basically the same length. The first insertion part 101 is inserted into the short frame and then riveted. Its back is without grooves. The second insertion part 102 is inserted into the long frame that has been riveted, so it is snapped together. Therefore, the outer wall of the second insertion part 102 is provided with two snap-fit ​​grooves 103.

[0003] Chinese patent CN210139008U discloses an automatic assembly machine for photovoltaic frame corner codes. This equipment includes a riveting machine, a base plate, a corner code moving mechanism, and a vibratory feeder. The corner codes are riveted on the base plate by the riveting machine. The corner code moving mechanism connects the outlet end of the vibratory feeder to the top of the base plate. The vibratory feeder delivers the corner codes in a regular arrangement with one right angle facing downwards, thus automatically feeding them to the riveting machine for individual riveting. However, the two right angles of the corner codes here have different lengths, which the vibratory feeder can distinguish in advance. However, in the aforementioned corner code 100, automatic feeding encounters the problem of not being able to distinguish which of the first insertion part 101 and the second insertion part 102 is on top. If the corner code 100 is misaligned, the frame assembly cannot be completed. This is because although the second insertion part 102 can be installed into the short frame, the first insertion part 101 does not have a position for the long frame to be riveted, so the entire frame will disintegrate. Theoretically, there is about a 50% probability that the corner brackets provided by the vibratory feeder are placed in the wrong position, which will prevent automatic feeding from being achieved.

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

[0005] The main purpose of this utility model is to provide a corner code feeding device that can automatically distinguish whether there is a snap-fit ​​groove on the upper insertion part of the corner code, thereby screening out corner codes with incorrect posture in advance and ensuring that the corner code is in the correct position when it is pressed.

[0006] This utility model achieves the above objective through the following technical solution: a corner code feeding device, comprising:

[0007] Vibratory feeder, including a discharge track extending along the X direction;

[0008] A blocking platform located at the outlet of the discharge track;

[0011] The first side push mechanism, located on the other side of the blocking platform in the Y direction, includes a first side push cylinder and a first push block driven by the first side push cylinder in the Y direction. The first push block is capable of moving the correctly oriented corner code from the blocking platform to the inlet of the corner code moving assembly.

[0012] A screening component, electrically connected to the vision component, receives electrical signals and is capable of screening out incorrectly oriented corner codes from the blocking tray.

[0013] Specifically, the blocking platform has a rejection position on the X-direction side, and the screening mechanism includes an X-direction moving module, a Z-direction moving module driven by the X-direction moving module to move along the X-direction, and a rejection gripper driven by the Z-direction moving module.

[0014] Furthermore, a corner code positioning sensor is provided near the blocking platform to detect the corner code's arrival on the blocking platform.

[0015] Specifically, the vision component includes an adjustment bracket, an industrial camera mounted on the adjustment bracket, and a surface light source located in front of the lens of the industrial camera.

[0016] Specifically, the shooting position of the vision component is the outer wall of the upper insertion part of the corner code. The corner code includes a first insertion part and a second insertion part that are vertically connected. The upper insertion part is either the first insertion part or the second insertion part. The outer wall of the second insertion part is provided with a snap-fit ​​groove.

[0017] Furthermore, the corner code moving assembly includes a conveyor belt for conveying corner codes along the X direction, a front stop block located at the inlet side of the conveyor belt, an upper baffle located above the conveyor belt, and a rear stop block located at the outlet side of the conveyor belt. A channel is formed between the conveyor belt and the upper baffle to accommodate the movement of the first insertion part. The first side pushing mechanism pushes the corner code with the correct posture to the rear of the front stop block. A sensor for detecting the passage of the upper part of the corner code is provided on one side of the conveyor belt.

[0018] Another major objective of this invention is to provide a photovoltaic corner code riveting device that can rivet the correctly positioned corner code to the frame as a whole.

[0019] This utility model achieves the above objectives through the following technical solution: a photovoltaic corner code pressing and riveting device, comprising a second side push mechanism, a pressing and riveting assembly, and the corner code feeding device;

[0020] The second side push mechanism is located on the Y-direction side of the corner code moving assembly, and the riveting assembly is located on the other Y-direction side. The second side push mechanism includes a second side push cylinder and a second push block driven by the second side push cylinder along the Y-direction. The second push block pushes the corner code from the front of the rear blocking frame to the lower part of the riveting assembly.

[0021] Specifically, the riveting assembly includes a riveting support block for supporting the end of the frame, pneumatic grippers for clamping the frame from both sides in the Y direction, a pressing mechanism for pressing the frame onto the riveting support block from top to bottom, and a riveting mechanism for riveting the frame and corner code together from top to bottom.

[0022] Furthermore, a frame positioning sensor is provided on one side of the pneumatic gripper to detect the arrival of the frame.

[0023] Furthermore, the rear blocking frame is provided with a blocking swing block and an elastic element. The blocking swing block is rotatably connected to the rear blocking frame along a vertical axis. The blocking swing block has a long arm that blocks the second side push mechanism and the rivet support block, and a short arm that is connected to the rear blocking frame by the elastic element.

[0024] The beneficial effects of this utility model's technical solution are:

[0025] 1. This corner code feeding device can automatically distinguish whether there is a snap-fit ​​groove on the upper insertion part of the corner code through the vision component, thereby filtering out corner codes with incorrect posture in advance through the screening component. Corner codes with correct posture are sent to the riveting component by the corner code moving component to ensure that the corner code is riveted correctly.

[0046] The present invention will be further described in detail below with reference to specific embodiments.

[0047] Example 1:

[0048] like Figures 1 to 3As shown, a photovoltaic corner code riveting device 200 of this utility model includes a corner code feeding device, a second side-pushing mechanism 8, and a riveting assembly 7. The corner code feeding device includes a vibratory feeder 1, a blocking support 2, a corner code moving assembly 3, a first side-pushing mechanism 4, a vision assembly 5, and a screening assembly 6. The corner code 100 includes a first insertion part 101 and a second insertion part 102 that are vertically connected. The outer wall of the second insertion part 102 is provided with a snap-fit ​​groove 103.

[0049] like Figure 1 and Figure 7 As shown, the vibratory feeder 1 includes a discharge track 11 extending along the X direction, and a blocking platform 2 located at the outlet 1 of the discharge track 11. Near the blocking platform 2 is a corner code positioning sensor 21 for detecting the corner code 100 arriving at the blocking platform 2. The X and Y directions are both in the horizontal plane and perpendicular to each other, while the Z direction is vertical.

[0050] The vibrating plate 1 is used to vibrate and arrange the corner codes 100. At this time, the side of the corner code 100 faces forward, and the shooting position of the vision component 5 is on the outer wall of the upper insertion part of the corner code 100. The upper insertion part is either the first insertion part 101 or the second insertion part 102. That is, when the first insertion part 101 is vertical and the second insertion part 102 is horizontal, the posture of the corner code 100 is incorrect; when the second insertion part 102 is upward, the first insertion part 101 is horizontal, and the corner positions of the two insertion parts are closer to the first side push mechanism 4, the posture of the corner code 100 is correct. The blocking platform 2 has an L-shaped structure and has two functions: blocking the forward movement of the corner code 100 and supporting the corner code 100. After the corner code positioning sensor 21 detects that a corner code 100 has arrived on the blocking platform 2, the screening can begin.

[0051] like Figure 2 As shown, the vision component 5 is located diagonally above the blocking platform 2 and is capable of capturing the position where the locking slot 103 on the corner code 100 should be. The vision component 5 includes an adjustment bracket 51, an industrial camera 52 mounted on the adjustment bracket 51, and a surface light source 53 located in front of the lens of the industrial camera 52. The inlet of the corner code moving component 3 is located on the Y-direction side of the blocking platform 2, and the first side-pushing mechanism 4 is located on the other Y-direction side of the blocking platform 2. The first side-pushing mechanism 4 includes a first side-pushing cylinder 41 and a first push block 42 driven by the first side-pushing cylinder 41 along the Y-direction. The first push block 42 moves the corner code 100 with the correct posture from the blocking platform 2 to the inlet of the corner code moving component 3. The screening component 6 is located above the blocking platform 2 and is electrically connected to the vision component 5. The screening component 6 receives electrical signals and is capable of screening out corner codes 100 with incorrect posture from the blocking platform 2.

[0052] Because when corner bracket 100 reaches blocking support 2, the first insertion part 101 may be on top, or the second insertion part 102 may be on top. Only corner bracket 100 with the second insertion part 102 on top can be used normally. Therefore, the vision component 5 is needed to identify whether the upper insertion part of corner bracket 100 has an insertion slot 103. The adjusting bracket 51 can flexibly adjust the lens direction of industrial camera 52 so that the lens can be pointed towards the position of insertion slot 103. The surface light source 53 is used to illuminate the surface of insertion slot 103 so that industrial camera 52 can capture clear images and avoid misjudgment caused by insufficient natural lighting conditions. If the industrial camera 52 can capture the insertion slot 103, it indicates that the angle code 100 is in the correct orientation. At this point, the first side-push cylinder 41 will drive the first push block 42 to eject the angle code 100 into the angle code moving assembly 3. This allows the angle code moving assembly 3 to deliver the correctly oriented angle code 100 to the riveting assembly 7. Otherwise, the screening assembly 6 will remove the incorrectly oriented angle code 100 for recycling, so that it can be supplied to the vibratory feeder 1 for rearrangement. The angle code moving assembly 3 only needs to deliver the correctly screened angle code 100 to the riveting assembly 7, and the conveying direction only needs not conflict with the first side-push mechanism 4 and the vibratory feeder 1. The conveying method of the angle code moving assembly 3 can be translational conveying, rotary conveying, etc. This corner code feeding device can automatically distinguish whether there is a snap-fit ​​groove 103 on the upper insertion part of the corner code 100 through the vision component 5, thereby filtering out the corner codes 100 with incorrect posture in advance through the screening component 6. The corner codes 100 with correct posture are sent to the riveting component 7 by the corner code moving component 3 to ensure that the corner code 100 is riveted correctly.

[0053] like Figure 3 As shown, the blocking platform 2 has a rejection position 9 on the X-direction side, and the screening mechanism 6 includes an X-direction moving module 61, a Z-direction moving module 62 driven by the X-direction moving module 61 to move along the X-direction, and a rejection gripper 63 driven by the Z-direction moving module 62.

[0054] The rejection position 9 is actually located in the discharge direction of the discharge track 11. The upper part of the blocking platform 2 is unobstructed, so the rejection gripper 63 can pick up the incorrectly positioned corner piece 100 by gripping the first insertion part 101. The X-axis moving module 61 and the Z-axis moving module 62 enable the rejection gripper 63 to move within a certain range in the XZ plane. The Z-axis moving module 62 drives the rejection gripper 63 to rise, allowing the corner piece 100 to pass over the highest position of the blocking platform 2 and move above the rejection position 9. When the rejection gripper 63 releases, the corner piece 100 falls into the rejection position 9.

[0055] Example 2:

[0056] like Figures 2 to 4As shown, the difference from Embodiment 1 is that the corner code moving assembly 3 includes a conveyor belt 31 for conveying the corner code 100 along the X direction, a front stop 32 located on the inlet side of the conveyor belt 31, an upper baffle 33 located above the conveyor belt 31, and a rear stop 34 located on the outlet side of the conveyor belt 31. A channel is formed between the conveyor belt 31 and the upper baffle 33 to accommodate the movement of the first insertion part 101. The first side pushing mechanism 4 pushes the corner code 100 with the correct posture to the rear of the front stop 32. A pass sensor 37 for detecting the upper part of the corner code 100 is provided on one side of the conveyor belt 31.

[0057] According to the discharge method of the vibratory feeder 1, the width direction of the corner code 100 is along the X direction, so the corner codes 100 can be arranged relatively compactly on the conveyor belt 31. According to the screening rules, the corner code 100 entering the corner code moving assembly 3 must have the second insertion part 102 on top and the first insertion part 101 on the bottom. Therefore, during the movement of the corner code 100 on the conveyor belt 31, the second insertion part 102 is on the Y-direction side of the upper baffle 33. To prevent the corner code 100 from tipping over due to instability, the upper baffle 33 must limit the first insertion part 101. The corner code 100 stops when it contacts the rear stop frame 34. The passage of the corner code 100 can be sensed by the sensor 37 to ensure that riveting is only performed when a corner code 100 passes by.

[0058] Example 3:

[0059] like Figure 3 and Figure 5 As shown, the difference from Embodiment 2 is that the second side-pushing mechanism 8 is located on the Y-direction side of the corner code moving assembly 3, and the riveting assembly 7 is located on the other Y-direction side. The second side-pushing mechanism 8 includes a second side-pushing cylinder (not exposed) and a second push block 81 driven by the second side-pushing cylinder along the Y-direction. The second push block 81 pushes the corner code 100 from the front of the rear stop frame 34 to the lower part of the riveting assembly 7. The riveting assembly 7 includes a riveting support block 71 supporting the end of the frame, pneumatic grippers 72 clamping the frame from both sides in the Y-direction, a pressing mechanism 73 pressing the frame onto the riveting support block 71 from top to bottom, and a riveting mechanism 74 riveting the frame and corner code together from top to bottom. A frame positioning sensor 75 for detecting the arrival of the frame is provided on one side of the pneumatic gripper 72.

[0060] After the corner bracket 100 reaches the end of the corner bracket moving assembly 3, the second side pushing mechanism 8 uses the second push block 81 to separate the corner brackets 100 one by one, so as to rivet them to the frame at the riveting assembly 7. The frame positioning sensor 75 can first detect that the frame has reached the riveting position, and then the pneumatic gripper 72 clamps the two ends of the frame from both sides in the X direction. At this time, the length direction of the frame is along the Y direction, and the end of the frame is above the riveting support block 71 with the end face facing the second push block 81. In this way, the second push block 81 can push the corner bracket 100 into the frame, so that the first insertion part 101 is inserted into the frame, and the frame is also adjusted to the Y direction position. The clamping mechanism 73 is used to clamp the frame with the corner bracket 100, so as to prevent the frame from moving during the riveting by the riveting mechanism 74 and ensure the riveting quality.

[0061] The rear stop frame 34 is provided with a stop block 35 and an elastic element 36. The stop block 35 is rotatably connected to the rear stop frame 34 along a vertical axis. The stop block 35 has a long arm 351 that blocks the second side push mechanism 8 and the rivet support block 71, and a short arm 352 that is connected to the rear stop frame 34 by the elastic element 36.

[0062] When corner bracket 100 moves to the end of corner bracket moving assembly 3, the blocking swing block 35, under the action of elastic element 36, will have its long arm 351 abut against the inner wall of the second insertion part 102 (the second insertion part 102 is in a vertical state), thereby preventing corner bracket 100 from slipping towards the riveting support block 71 and affecting the riveting of the previous corner bracket 100. When the second push block 81 pushes the corner bracket 100, the blocking swing block 35 can overcome the elastic force of elastic element 36 and swing outward to make way. After the corner bracket 100 passes the long arm 351 and the second push block 81 retracts, the blocking swing block 35 automatically resets. In the figure, elastic element 36 is a tension spring, which can be replaced by torsion springs, compression springs, etc. in actual applications. The blocking swing block 35 is not limited to rotating around the Z-axis, but can also rotate around the X-axis.

[0063] The working process of this photovoltaic corner code pressing and riveting equipment 200 is as follows:

[0064] The disordered corner brackets 100 are poured into the vibratory feeder 1. The vibratory feeder 1 arranges the corner brackets 100 and sends them out from the discharge track 11. At this time, the first insertion part 101 or the second insertion part 102 of the corner bracket 100 is randomly placed on top. When the corner bracket 100 reaches the blocking support 2, it will be detected by the corner bracket positioning sensor 21. At this time, with the assistance of the surface light source 53, the industrial camera 52 will take a picture of the outer wall of the upper insertion part of the corner bracket 100. If the snap-fit ​​groove 103 is not identified on the outer wall, then the first insertion part 101 of the insertion part and the corner code 100 are in an incorrect posture. In this case, the rejection gripper 63 will pick up the corner code 100 and place it in the rejection position 9. If the snap-fit ​​groove 103 is identified on the outer wall, then the insertion part is the second insertion part 102 and the corner code 100 is in an correct posture. In this case, the first side push cylinder 41 will drive the first push block 42 to push the corner code 100 into the inlet of the conveyor belt line 31. The conveyor belt line 31 will then arrange the corner code 100 and transport it backward until the corner code 100 is blocked by the rear stop bracket 34. At this time, the long arm 351 will prevent the corner code 100 from moving onto the rivet support block 71. When the frame moves into the sensing area of ​​the frame positioning sensor 75, the pneumatic gripper 72 clamps the end of the frame. At this time, the end face of the frame is above the riveting support block 71 and facing the corner bracket 100. The second side push cylinder drives the second push block 81 to push the corner bracket 100 out. The corner bracket 100 pushes open the long arm 351, and then the first insertion part 101 is inserted into the frame, adjusting the frame to a suitable Y-direction position. Subsequently, the second push block 81 retracts. The clamping mechanism 73 clamps the frame, and the riveting mechanism 74 rivets the frame and the corner bracket 100 together.

[0065] 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.
