[0002] Photovoltaic frames are important components of solar panels. They have high structural strength and provide mechanical protection for solar panels to avoid damage to the panels during handling and transportation. After anodizing, the frame surface has good insulation properties to ensure the safety of solar panels in exposed working environments. Photovoltaic aluminum frames consist of two long sides, two short sides and corner brackets. The corner brackets need to be pressed together with the short side profiles. The existing steel frame production lines can basically meet daily use needs, but there are still some shortcomings that need to be improved.

However, there is another type of corner code in an inverted V-shaped posture, that is, both ends are supported downward on the conveyor belt. The corner code in this state is usually difficult to correct by turning, and it is necessary to exclude the conveyor. Therefore, there is an urgent need for an automatic feeding device for steel frame corner codes to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic feeding device for steel frame corner brackets to solve the above-mentioned shortcomings in the prior art.

When the angle code conveyed in an inverted V-shaped posture moves on the conveying platform and passes through the detection slot, this type of angle code will press the detection plate, causing the detection plate to rotate downward, and the angle code itself is embedded in the detection slot with one end, which prompts the detection plate to rotate to the maximum angle, thereby triggering the linkage component.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] See also Figure 1-7 An automatic feeding device for steel frame angle codes provided by an embodiment of the present invention comprises a frame 1, on which a conveying platform 2 for conveying angle codes in a single row is arranged, and further comprises: a detection slot 3, which is opened on the conveying platform 2; a detection plate 4, which is elastically hinged in the detection slot 3; an impact rod 5, which is movably arranged below the detection slot 3; a linkage component, which is used to link the detection plate 4 and the impact rod 5, when the angle code conveyed in an inverted V-shaped posture passes through the detection slot 3, the detection plate 4 is pressed to rotate, and when the rotation reaches the maximum angle, the linkage component links the impact rod 5 to trigger the pop-up to push the angle code embedded in the detection slot 3 out of the conveying platform 2.

[0033] Specifically, the frame 1 is used to support the angle code conveying structure; a transition bridge is provided on the frame 1 corresponding to the conveying end of the conveying platform 2, and a conveyor belt for connecting with other production line structures is provided on the transition bridge; the length direction of the conveying platform 2 corresponds to the conveying direction of the angle code; the width of the conveying platform 2 matches the corresponding width when the angle code is erected in an L shape and the lower end is arranged along the conveying direction; the angle code is on the conveying platform 2, and there are two postures in which it is erected in an L shape, but with the lower end of the conveying platform 2 pointing in opposite directions, and there is another posture in an inverted V shape, that is, the two ends of the angle code are supported downward on the conveying platform 2, and the angle codes in other postures will also be transformed into the above three postures due to the action of gravity when they log on to the conveying platform 2; the upper surface of the conveying platform 2 is set smoothly, and the angle code slides on the conveying platform 2 along the length direction of the conveying platform 2. The detection slot 3 is set to form a circuit breaker on the conveying platform 2. The size of the detection slot 3 is larger than the corresponding size of one end of the angle code, that is, the angle code can move one end in and out of the detection slot 3; one side of the detection slot 3 extends to the edge of the conveying platform 2 to be open, and the inverted V-shaped angle code is discharged from the conveying platform 2 through the open side of the detection slot 3. The rotating shaft of the detection plate 4 is horizontal and perpendicular to the conveying direction of the angle code. The rotating shaft of the detection plate 4 is set in the detection slot 3 on the side away from the starting direction of the conveying direction of the angle code; under the action of elasticity, the detection plate 4 keeps the free end horizontal and flush with the upper surface of the conveying platform 2; when the detection plate 4 is pressed by the gravity of the angle code passing thereon, it can rotate downward, and the maximum angle of downward rotation is preferably around 90°. The ejection direction of the impact rod 5 points to the open side of the detection slot 3 and is parallel to the axial direction of the rotating shaft of the detection plate 4; the angle code embedded in the detection slot 3 can be in the ejection movement range of the impact rod 5; the impact rod 5 that has not been ejected remains retracted in the frame 1 to avoid affecting the embedding of the angle code in the detection slot 3. The angle code passing through the detection slot 3 in an L-shaped posture is supported by a whole plane of the lower surface, so the gravity is shared on the conveying platform 2 and the detection plate 4, and the detection plate 4 will not rotate downward at a large angle at this time; while the angle code passing through the detection slot 3 in an inverted V-shaped posture, one end of which is supported directly on the detection plate 4, thereby applying most of the gravity to the detection plate 4, so that the detection plate 4 is pushed to rotate downward, and as one end of this type of angle code is embedded in the detection slot 3, the detection plate 4 is further pushed to reach the maximum angle, thereby triggering the linkage component, and the linkage component is then linked to the impact rod 5 to trigger the pop-up to realize the function of pushing the angle code embedded in the detection slot 3 out of the conveying platform 2. Among the two types of angle codes standing on the conveying platform 2 in an L-shaped posture, the one with the lower end pointing to the conveying direction is the first posture, which can be used directly in the subsequent use, and the other one with the lower end pointing in the opposite direction is the second posture, which can be used after correction; the angle code in the inverted V-shaped posture is the third posture, which needs to be discharged from the conveying platform 2.In actual use of the present technical solution, when an angle code conveyed in an inverted V-shaped posture moves on the conveying platform 2 and passes through the detection slot 3, one end of such angle code will directly support on the detection plate 4, and most of its gravity will be applied to the detection plate 4, forcing the detection plate 4 to rotate downward, and the angle code itself is embedded in the detection slot 3 with one end, which also prompts the detection plate 4 to rotate to the maximum angle, thereby triggering the linkage component, and the linkage impact rod 5 is triggered to pop up to push the angle code embedded in the detection slot 3 out of the conveying platform 2, ensuring that the posture of the angle code finally conveyed by the conveying platform 2 is correct or meets the correction conditions.

[0034] Compared with the prior art, an automatic feeding device for steel frame angle codes proposed in an embodiment of the present invention provides a detection plate 4. When an angle code conveyed in an inverted V-shaped posture moves on the conveying platform 2 and passes through the detection slot 3, such an angle code will press the detection plate 4, causing the detection plate 4 to rotate downward, and the angle code itself is embedded in the detection slot 3 with one end, thereby prompting the detection plate 4 to rotate to the maximum angle, thereby triggering the linkage component, and the linkage impact rod 5 is triggered to pop up to push the angle code embedded in the detection slot 3 out of the conveying platform 2, thereby ensuring that the posture of the angle code finally conveyed by the conveying platform 2 is correct or meets the correction conditions.

[0035] As a preferred technical solution of this embodiment, the rotating shaft of the detection plate 4 is coaxially connected with the linkage shaft 6 rotatably arranged in the frame 1, and the linkage shaft 6 is physically connected to the frame 1 through the coil spring 25. Specifically, a connecting cavity is physically arranged in the frame 1, and one end of the inner circle of the coil spring 25 is fixedly connected to the outer wall of the linkage shaft 6, while one end of the outer circle is connected to the inner wall of the connecting cavity. The setting of the coil spring 25 limits the free rotation of the detection plate 4 through the linkage shaft 6, and makes the detection plate 4 correspond to the position where the free end is horizontal and flush with the upper surface of the conveying platform 2 when it is not under force. In addition, it is also preferred that a torsion spring replaces the coil spring 25 to limit the rotation of the linkage shaft 6.

[0036] As a preferred technical solution of this embodiment, the linkage component includes a displacement member 7 movably arranged in the frame 1 entity, one end of the displacement member 7 is connected to the linkage shaft 6 with a spiral transmission, and the other end is connected to the impact rod 5 through a first elastic member 8. A limit assembly for limiting the impact rod 5 from popping out is arranged in the frame 1. When the detection plate 4 rotates to reach the maximum angle, the limit assembly cancels the limit. Specifically, an active cavity is arranged in the frame 1 entity, and the displacement member 7 moves in the active cavity, and the active direction is arranged axially along the linkage shaft 6; the rotation of the linkage shaft 6 links the displacement member 7 to move; the first elastic member 8 can preferably be a spring; a groove is arranged at one end of the impact rod 5 close to the displacement member 7, and one end of the first elastic member 8 The end extends into and is connected in the groove, thereby reducing the required length of the linkage shaft 6 and ensuring stable transmission; before the limit assembly cancels the movement of the limit impact rod 5, the detection plate 4 drives the linkage shaft 6 to rotate, and the linkage displacement member 7 moves, and the displacement member 7 first forces the first elastic member 8 to deform and store elastic potential energy; when the detection plate 4 rotates to the maximum angle, the limit assembly cancels the limit, that is, the elastic potential energy of the first elastic member 8 is released, so that the impact rod 5 is ejected in the direction of pushing the angle code; in addition, when the detection plate 4 is reversed under the action of the coil spring 25, the impact rod 5 is directly linked to the linkage assembly for reset movement, and the limit assembly also limits the impact rod 5 again when the impact rod 5 completes the reset.

[0037] As the preferred technical scheme of this embodiment, a spiral groove 9 is provided on the linkage shaft 6, and a sliding sleeve 10 is provided at one end of the displacement member 7 and is sleeved on the linkage shaft 6. A sliding protrusion 11 which is slidably connected to the spiral groove 9 is provided on the inner wall of the sliding sleeve 10. Specifically, the spiral groove 9 may preferably be multiple and evenly distributed around the circumference of the axis of the linkage shaft 6; the sliding sleeve 10 slides along its axial direction on the linkage shaft 6; the relative sliding of the sliding protrusion 11 and the spiral groove 9, that is, the spiral transmission of the linkage shaft 6 and the sliding sleeve 10 occurs. In actual use, the detection plate 4 drives the linkage shaft 6 to rotate to trigger the relative sliding of the spiral groove 9 and the sliding protrusion 11, thereby driving the sliding sleeve 10 and the displacement member 7 to move. Specifically, when the detection plate 4 rotates downward, the displacement member 7 moves toward the direction close to the impact rod 5, and when the detection plate 4 rotates upward, the displacement member 7 moves away from the impact rod 5.

[0038] As a preferred technical solution of this embodiment, the limit assembly includes a swing rod 12 rotatably arranged in the frame 1 entity, one end of the swing rod 12 is close to the linkage shaft 6 and a cam 13 is arranged at the corresponding position of the linkage shaft 6, the other end of the swing rod 12 is close to the impact rod 5, and a limit groove 14 is arranged on the impact rod 5, and the swing rod 12 is connected to the frame 1 entity through a second elastic member 15. Specifically, a limit cavity is arranged in the frame 1 entity, and the swing rod 12 is rotatably arranged in the limit cavity. The second elastic member 15 can preferably be a spring, one end of the second elastic member 15 is fixedly connected to the swing rod 12, and the other end is connected to the inner wall of the limit cavity, and the second elastic member 15 keeps the swing rod 12 taut so that one end of the swing rod 12 keeps in contact with the outer ring surface of the cam 13; when the detection plate 4 rotates to the maximum angle, the cam 13 is perpendicular to the swing rod 12 at the outer ring position with the largest outer diameter. At this time, the other end of the swing rod 12 leaves the range of the limit groove 14; the limit groove 14 is preferably an annular groove opened on the outer wall of the impact rod 5, and is arranged close to the end of the impact rod 5 extending out.

[0039] The linkage relationship between the detection plate 4 and the impact rod 5 is described in detail below:

[0040] In actual use, the detection plate 4 is first in a horizontal position at the free end, and the limit assembly maintains the limit impact rod 5; when the detection plate 4 is pressed by one end of the angle code in an inverted V-shaped posture, the detection plate 4 rotates downward, and the detection plate 4 drives the linkage shaft 6 to rotate, and the linkage shaft 6 drives the coil spring 25 to deform and store elastic potential energy. The rotation of the linkage shaft 6 also causes the spiral groove 9 and the sliding cam 11 to slide relative to each other, so that the sliding sleeve 10 drives the displacement member 7 to move closer to the impact rod 5. The impact rod 5 is stationary at this time, and the first elastic member 8 is compressed and stores elastic potential energy. As one end of the angle code is embedded in the detection groove 3, the detection plate 4 rotates to the maximum angle. At this time, the linkage shaft 6 drives the cam 13 to rotate to the maximum outer diameter position against the rocker rod 12, and the rocker rod 12 rotates to separate its other end from the limit groove 14. As a result, the elastic potential energy of the first elastic member 8 is released, and the impact rod 5 pops out smoothly to push the angle code embedded in the detection groove 3 out of the conveying platform 2. After the angle code leaves the detection groove 3, the detection plate 4 rotates upward and resets under the action of the coil spring 25, and then the displacement member 7 moves back through the spiral groove 9, the sliding protrusion 11 and the sliding sleeve 10. The displacement member 7 then pulls the impact rod 5 to reset through the first elastic member 8. When the limit groove 14 and the rocker arm 12 correspond again, the rocker arm 12 is re-embedded in the limit groove 14 under the action of the second elastic member 15, and the impact rod 5 is limited again.

[0041] As a preferred technical solution of this embodiment, a receiving groove 16 matching the impact rod 5 is provided in the frame 1 entity, and one end of the displacement member 7 connected to the impact rod 5 is movably arranged in the receiving groove 16. Specifically, when the impact rod 5 is contracted, it is in the receiving groove 16, and the receiving groove 16 limits the moving direction of the impact rod 5. One end of the displacement member 7 connected to the impact rod 5 is provided with a round block matching the receiving groove 16, thereby also limiting the displacement member 7 to move along the receiving groove 16 without rotating, thereby ensuring that the sliding sleeve 10 at the other end of the displacement member 7 and the independently rotating linkage shaft 6 have a spiral transmission effect.

[0042] In another embodiment of the present invention, a support plate 17 located on one side of the conveyor platform 2 is provided on the frame 1, and a plurality of support wheels 18 are rotatably provided on the support plate 17, and the plurality of support wheels 18 are rollingly connected to the same rolling belt 19, and a plurality of push rods 20 are equidistantly arranged on the side of the rolling belt 19 facing the conveyor platform 2. Specifically, the support plate 17 is arranged on the opposite side of the open side of the detection slot 3; the support wheel 18 is controlled by a servo motor, and the axial direction of the support wheel 18 is horizontal and perpendicular to the conveying direction of the angle code; the support wheel 18 can be preferably a sprocket, a synchronous wheel, etc., and the rolling belt 19 can be preferably a chain, a belt, etc.; the length of the push rod 20 meets the width range across the conveyor platform 2; when the push rod 20 passes through the circulating lower part of the rolling belt 19, it can just push the upper part of the angle code of various postures conveyed on the conveyor platform 2, and when the push rod 20 passes through the circulating upper part of the rolling belt 19, it is higher than the angle code of various postures conveyed on the conveyor platform 2; one push rod 20 pushes one angle code to move. In addition, when the push rod 20 pushes the inverted V-shaped angle code, the force-applying surface of the angle code is an inclined surface. Therefore, when the angle code passes through the detection groove 3, it can be more easily pressed against the detection plate 4 by the push force of the push rod 20 to facilitate the subsequent function of sending out the angle code.

[0043] In another embodiment of the present invention, a height difference is set between one end of the rotating shaft of the detection plate 4 and the upper surface of the conveying platform 2, and the other end of the detection plate 4 is set flush with the upper surface of the conveying platform 2 in its elastic free state. Specifically, the height difference between one end of the rotating shaft of the detection plate 4 and the upper surface of the conveying platform 2 is set to assist the angle code of the second posture to correct to the first posture, specifically: the center of gravity of the angle code of the second posture is forward along the conveying direction. When the angle code of the second posture begins to pass through the detection slot 3, it is still supported by the conveying platform 2 and will not immediately press down the detection plate 4. When the center of gravity moves to the detection plate 4, the detection plate 4 begins to be pressed down. At this time, the detection plate 4 is pressed to rotate downward at a smaller angle and with the rotating shaft. One end supports the angle code of the second posture, so that the conveying front end of this type of angle code can be against the height difference between the detection plate 4 and the conveying platform 2. At the same time, the upper end of the angle code is always pushed by the push rod 20, thereby causing the angle code of the second posture to flip nearly 90° along the conveying direction to switch to the first posture and continue to be conveyed on the conveying platform 2; the center of gravity of the angle code of the first posture is backward along the conveying direction. When the angle code of the first posture passes through the detection slot 3, its center of gravity will correspond to the detection plate 4 only after its conveying front end crosses the detection slot 3. At the same time, since the upper end of the angle code is always pushed by the push rod 20, the angle code of the first posture will not be affected by the height difference between the detection plate 4 and the conveying platform 2, and maintains its first posture through the detection slot 3.

[0044] As a preferred technical solution of the above embodiment, an obstacle avoidance opening 21 for avoiding the pop-up position of the impact rod 5 is provided on the detection plate 4. Specifically, after the impact rod 5 pops out, it is located at the lower side of the detection slot 3, and the rotation range of the detection plate 4 interferes with the extended impact rod 5. The setting of the obstacle avoidance opening 21 can eliminate the above interference without affecting the detection function of the detection plate 4.

[0045] As a preferred technical solution of the above embodiment, a feeding belt 22 is arranged on the frame 1, and a step loading assembly 23 is arranged between the feeding belt 22 and the conveyor platform 2, and a partition 24 is arranged on the feeding belt 22. Specifically, the feeding belt 22 conveys two rows of angle codes under the spacing action of the partition 24, and the step loading assembly 23 lifts one or two angle codes at a time and sends them to the conveyor platform 2, and is adapted to the rolling belt 19. When the angle code enters the conveyor platform 2, it is just between the two push rods 20.

[0046] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
