Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module production technology, and in particular relates to a profile feeding mechanism. Background Technology

[0002] Traditional photovoltaic module frames are roughly square, which not only have a complex structure and are prone to dust accumulation at the contact point between the frame and the glass, but also have high production costs. A new frame has been redesigned that is not only simple in structure and less prone to dust accumulation, but also has low production costs. The new frame is made by bending and welding two profiles with an "L" cross-section. Before bending and welding, the profiles need to be transported to a processing table. Moreover, the profiles have different postures on the feeding table and on the processing table. The posture of the profiles also needs to be adjusted during the transportation process. Therefore, an automated feeding mechanism needs to be designed that can not only transport the profiles with an "L" cross-section, but also adjust the posture of the profiles.

[0003] A high-efficiency feeding device for aluminum frames of photovoltaic modules, disclosed in Chinese Patent Publication No. CN222373654U, includes a handling and clamping unit for handling frames. The handling and clamping unit includes a flipping bracket, a clamping module disposed on the flipping bracket and corresponding to the number of frame conveying lines, and a third motor that drives the flipping bracket to flip around a horizontal axis to switch the clamping module between a vertically spaced distribution state and a horizontally spaced distribution state. In this solution, the third motor drives the flipping bracket to flip, rotating several horizontally arranged frames into vertically arranged frames, but without changing the posture of individual frames, so it is impossible to adjust the posture of a single profile. Moreover, the clamping module grips the frames by using a cylinder to drive a pair of clamping blocks, which is prone to frame slippage and cannot clamp profiles with an "L" shaped cross-section.

[0004] Therefore, it is necessary to provide a profile feeding mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a profile feeding mechanism that can adjust the posture of the profile and more firmly adsorb the profile, thus avoiding the risk of the profile falling.

[0006] This utility model achieves the above objective through the following technical solution: a profile feeding mechanism, comprising:

[0007] An adsorption unit includes a first driving member and an adsorption block driven by the first driving member to adsorb a profile. The adsorption block is provided with a receiving groove that conforms to the longitudinal section of the profile, and an electromagnet is provided in the receiving groove.

[0008] A flipping frame, which is connected to the adsorption unit;

[0009] A flip drive module is connected to the flip frame to drive the flip frame to rotate about a horizontal axis.

[0010] Furthermore, the adsorption unit is provided in a plurality of units, and the adsorption unit further includes a mounting bracket for mounting the first driving component, and the plurality of mounting brackets are arranged at intervals on one side of the flipping frame.

[0011] Furthermore, some of the mounting brackets are equipped with sensing components for sensing profiles and / or a first sensor for detecting whether the adsorption block has adsorbed profiles.

[0012] Furthermore, the sensing component includes a material detection element movably disposed on the mounting bracket and a second sensor that senses the material detection element.

[0013] Furthermore, the material inspection element is horizontally mounted on the mounting bracket via a linear bearing. One end of the material inspection element is a contact head that contacts the profile, and the other end is a detection head for detection by the second sensor.

[0014] Furthermore, the flipping drive module includes a second drive member and a push rod that is driven by the second drive member to extend or retract, and the push rod is rotatably disposed on one side of the flipping frame via a first support shaft.

[0015] Furthermore, the second driving component is mounted on the lifting plate, which is driven by the third driving component to move up and down, and both the push rod and the lifting plate are inclined.

[0016] Furthermore, the tilting frame is rotatably mounted at the bottom of the lifting plate via a connecting assembly.

[0017] Furthermore, the connecting assembly includes a first connecting seat disposed at the bottom of the lifting plate and a second connecting seat disposed on the tilting frame, the second connecting seat being rotatably disposed on the first connecting seat via a second support shaft.

[0018] Furthermore, the bottom of the lifting plate is equipped with a buffer that can be adjusted vertically.

[0019] Compared with the prior art, the beneficial effects of this utility model's profile feeding mechanism are as follows:

[0020] (1) The set flipping drive module can drive the flipping frame to rotate around the horizontal axis to drive several adsorption units to rotate around the horizontal axis, which can make the profile rotate along the axis by a certain angle, thereby realizing the posture adjustment of the profile;

Even during the process of rotating the profile to adjust its posture, the risk of the profile falling off can be avoided. Attached Figure Description

[0035] Please refer to Figures 1-5This embodiment is a profile feeding mechanism 100. The profile feeding mechanism 100 includes a flipping frame 1, a plurality of adsorption units 2 disposed on the flipping frame 1 for adsorbing profiles 200, and a flipping drive module 3 for driving the flipping frame 1 to rotate around a horizontal axis. The plurality of adsorption units 2 are arranged at intervals on one side of the flipping frame 1. The adsorption unit 2 includes a first drive member 21 and an adsorption block 22 driven by the first drive member 21 to adsorb the profile. The adsorption block 22 is provided with a receiving groove 221 that conforms to the longitudinal section of the profile 200. An electromagnet 222 for adsorbing the profile 200 is disposed in the receiving groove 221. The adsorption unit 2 has an adsorption block 22 with a receiving groove 221. An electromagnet 222 is installed in the receiving groove 221. The profile is made of metal. When the electromagnet 222 is magnetic, it can adsorb the profile. When the electromagnet 222 is energized, it can magnetically adsorb the profile 200. When the power is off, the magnetism is lost and the profile 200 can be put down. The profile is magnetically adsorbed in the receiving groove 221, which makes the adsorption more reliable. Even when the profile is rotated to adjust its posture, the risk of the profile falling can be avoided.

[0036] The adsorption unit 2 also includes a mounting bracket 23 for mounting the first driving component 21. Several mounting brackets 23 are arranged at intervals on one side of the flip frame 1. Some mounting brackets 23 are provided with sensing components 24 for sensing the profile 200 and / or a first sensor 25 for detecting whether the adsorption block 22 has adsorbed the profile 200.

[0037] In this embodiment, a sensing component 24 and a first sensor 25 are installed on both the first mounting bracket 23 and the last mounting bracket 23. There are two sets of sensing components 24 and first sensors 25. The two sets of sensing components 24 and first sensors 25 work simultaneously, which can improve accuracy and precision and avoid misjudgment.

[0038] In other embodiments, the number and position of the sensing component 24 and the first sensor 25 can be adjusted adaptively, and the sensing component 24 and the first sensor 25 can also be mounted on different mounting brackets 23. Therefore, the number and position of the sensing component 24 and the first sensor 25 are not limited here.

[0039] The sensing component 24 includes a material detection element 241 movably mounted on the mounting bracket 23 and a second sensor 242 for sensing the material detection element 241.

[0040] The material detection element 241 is horizontally mounted on the mounting bracket 23 via a linear bearing 243. One end of the material detection element 241 is a contact head 2411 that contacts the profile 200, and the other end is a detection head 2412 for detection by the second sensor 242. Initially, the second sensor 242 is facing the detection head 2412 and can sense it. When the adsorption unit 2 approaches the profile 200, the contact head 2411 first contacts the profile 200, and then the profile 200 pushes the material detection element 241. At this time, the second sensor 242 can no longer sense the detection head 2412, so it sends a signal to the first driving component 21 to drive the adsorption block 22 to extend and adsorb the profile 200. To prevent the contact head 2411 from scratching the profile, the contact head 2411 can be made of rubber, plastic, or other soft materials. The specific material is selected according to the actual situation and is not limited here.

[0041] In this embodiment, the first driving component 21 is a cylinder, which drives the adsorption block 22 to extend and adsorb the profile 200. In other embodiments, the first driving component 21 can be set as a driving component of other types, such as a servo motor. The specific driving method of the first driving component 21 is not limited here.

[0042] Because the profile 200 is relatively long, in this embodiment, five adsorption units 2 and five mounting brackets 23 are provided. The five adsorption units 2 simultaneously adsorb the profile 200, ensuring stability during adsorption. In other embodiments, the number of adsorption units 2 and mounting brackets 23 can be set according to actual conditions, and there is no limitation here.

[0043] The flipping drive module 3 includes a second drive member 31 and a push rod 32 that is driven by the second drive member 31 to extend or retract. The push rod 32 is rotatably mounted on one side of the flipping frame 1 via a first support shaft 33. Two flipping drive modules 3 are arranged at the front and rear to ensure the stability of the movement of the flipping frame 1. In other embodiments, the number of flipping drive modules 3 can be adjusted, and is not limited here.

[0044] The second driving component 31 is mounted on the lifting plate 4. The lifting plate 4 is driven by the third driving component 5 to move up and down. The push rod 32 and the lifting plate 4 are both inclined, and the inclination angles are approximately the same. The inclination angles need to be adjusted according to the actual working conditions, and are not limited here.

[0045] The flipping frame 1 is rotatably mounted on the bottom of the lifting plate 4 via the connecting assembly 6. The connecting assembly 6 includes a first connecting seat 61 mounted on the bottom of the lifting plate 4 and a second connecting seat 62 mounted on the flipping frame 1. The second connecting seat 62 is rotatably mounted on the first connecting seat 61 via a second support shaft 63, thereby enabling the flipping frame 1 to be rotatably mounted on the bottom of the lifting plate 4 and ensuring the stability of the flipping frame 1 during flipping. When the second driving member 31 drives the push rod 32 to move to the lower right, the flipping frame 1 rotates around the second support shaft 63 as the fulcrum, thereby adjusting the profile posture. In this embodiment, when the profile 200 is adsorbed, the longitudinal section of the profile 200 is in a "<" posture. After rotating by a certain angle, approximately 45°, the longitudinal section of the profile 200 becomes an "L" posture. In other embodiments, a profile with an "L" posture can also be rotated to obtain a profile 200 with a "<" posture. This solution is not limited to adjusting the posture of L-shaped profiles, but can also adjust the posture of profiles of other shapes. The rotation angle is set according to the actual situation.

[0046] In this embodiment, two connecting components 6 are arranged at the front and rear to ensure the stability of the rotation of the flipping frame 1. In other embodiments, the number and position of the connecting components 6 can be adjusted according to the actual situation.

[0047] When the second driving component 31 retracts the push rod 32 to reset the tilting frame 1, the tilting frame 1 will approach the bottom of the lifting plate 4. To prevent the tilting frame 1 from over-rotating, a buffer 7 is provided at the bottom of the lifting plate 4. The buffer 7 is a hydraulic or oil-pressure buffer. The buffering principle of the hydraulic or oil-pressure buffer is existing technology and will not be elaborated here. Other buffers can also be used, and the choice can be made according to the actual application. No limitation is made here. The buffer 7 is adjustable in height at the bottom of the lifting plate 4 so as to adapt to the tilting frame 1 with different rotation angles. For example, when the rotation angle of the tilting frame 1 is small, the position of the buffer 7 can be adjusted downward; when the rotation angle of the tilting frame 1 is large, the position of the buffer 7 can be adjusted upward. In this embodiment, two buffers 7 are provided at the front and rear to ensure the buffering effect. In other embodiments, the number of buffers 7 can be set according to the actual situation, and buffers 7 can also be provided at other positions. Therefore, the number of buffers 7 and the installation position of the buffers are not limited here.

[0048] In this embodiment, the third driving component 5 is a motor, and a gear is provided at the output shaft end of the motor. A rack is provided on the lifting plate 4 to mesh with the gear for transmission. The lifting plate 4 is driven to move up and down through the gear and rack mechanism. In other embodiments, other methods may be used to drive the lifting plate 4 to move up and down, and no limitation is made here.

[0049] When the profile feeding mechanism 100 provided in this solution is applied, the profile feeding mechanism 100 moves to the profile feeding platform (not shown in the figure), and the third driving member 5 drives the lifting plate 4 to move to the profile 200 to be transported, so that the adsorption unit 2 is close to the profile 200. At this time, the longitudinal section of the profile 200 is in a "<" posture. The contact head 2411 of the material detection element 241 first contacts the profile 200, and then the profile 200 will push the material detection element 241. At this time, the second sensor 242 cannot detect the detection head 2412, so it sends a signal to the first driving member 21 to drive the adsorption unit 2. The attachment block 22 extends to adsorb the profile 200. After the electromagnet 222 is energized, it has magnetism to adsorb the profile 200. The profile is adsorbed into the receiving groove 221 of the adsorption block 22. Several adsorption blocks 22 simultaneously adsorb the profile 200. As soon as the first sensor 25 senses that the profile 200 is adsorbed on the adsorption block 22, the third drive component 5 drives the lifting plate 4 to rise to the set height. The second drive component 31 drives the push rod 32 to move to the lower right. The flipping frame 1 rotates around the second support shaft 63 as the rotation center, so that the longitudinal section of the profile changes from the "<" posture to the "L" posture. After the profile is rotated, the profile feeding mechanism 100 moves to the profile processing table (not shown in the figure) so that the adsorption unit 2 is close to the profile processing table. After the electromagnet 222 is de-energized, the profile 200 is placed on the profile processing table for processing. The profile feeding mechanism 100 continues to move to the profile feeding table (not shown in the figure) to transport the next profile.

[0050] 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.
