Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to an MC4 head wire nose automatic continuous sorting device. Background Technology

[0002] A wire lug is a small component used in electrical equipment wiring. With industrial development, the demand for wiring has increased significantly, leading to the widespread use of wire lugs and other small components for electrical equipment wiring. However, these components are typically piled up haphazardly, making regular sorting impossible. When these components are needed, the lack of a clear order necessitates manual handling, requiring each one to be retrieved one by one. This greatly reduces worker efficiency, is extremely inconvenient, lowers organizational profitability, and leads to numerous complex problems. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing wire noses cannot achieve regular sorting, are inconvenient to use, and affect overall work efficiency. To address this problem, an automatic continuous sorting device for MC4 wire noses is proposed, comprising a hopper, a stirring wheel, a feeding wheel, a conveyor belt, and a rotating adjustment disc. The stirring wheel is located inside the hopper, and the feeding wheel is located directly below the hopper outlet. The feeding wheel has two slots for receiving MC4 wire noses. The conveyor belt is located below the feeding wheel, and the rotating adjustment disc for adjusting the direction of the MC4 wire noses is located above the conveyor belt, between the hopper outlet and the conveyor belt outlet.

[0004] In this embodiment, the technical solution incorporates a hopper and a mixing wheel structure. Under the action of the mixing wheel, the MC4 head wire nose inside the hopper falls from the hopper outlet for subsequent processing. A structure with two slots on the feed roller receives the MC4 head wire nose, with one slot at the top and the other at the bottom, ensuring the received MC4 head wire nose falls onto the conveyor belt. A rotating adjustment disc allows the MC4 head wire nose to be adjusted to the desired orientation for direct handling and use.

[0005] In a preferred embodiment of the present invention, the outlet width b of the hopper is the same as the length of the MC4 head wire nose, and the MC4 head wire nose can smoothly fall into the slot of the feed roller through the outlet of the hopper.

[0006] In a preferred embodiment of the present invention, the stirring wheel is driven to rotate by a stirring motor, and the stirring wheel stirs the MC4 head wire nose in the hopper to prevent the MC4 head wire nose from becoming blocked at the outlet of the hopper.

[0007] In a preferred embodiment of the present invention, the two slots are symmetrically arranged on the edge of the feed roller, and the two axes of symmetry of the two slots both pass through the center of the feed roller. When the slot rotates to the top with the feed roller, it is located below the outlet of the hopper and can receive one MC4 head wire nose. The other slot is located at the bottom, and the MC4 head wire nose it receives falls onto the conveyor belt.

[0008] In a preferred embodiment of the present invention, the feeding impeller is driven to rotate by a feeding motor. A fixed outer cover is provided around the feeding impeller, and the cross-section of the outer cover is circular. The feeding impeller rotates to transfer the MC4 head wire nose from the hopper onto the conveyor belt. The outer cover can prevent the MC4 head wire nose from falling off before the feeding impeller has rotated to the correct position, thus avoiding affecting subsequent work.

[0009] In a preferred embodiment of the present invention, the outer cover has openings at both the top and bottom along the vertical direction. The size of the openings is the same as the size of the slots. The top opening is located directly below the outlet of the hopper, and the bottom opening is located above the conveyor belt. The top opening facilitates the MC4 head wire nose in the hopper to fall into the slot, and the bottom opening facilitates the MC4 head wire nose in the slot to fall onto the conveyor belt. The outer cover prevents the MC4 head wire nose from accidentally falling out of other positions.

[0010] In a preferred embodiment of the present invention, a first optical coupler and a second optical coupler are respectively provided at the upper and lower openings of the outer cover. The first optical coupler is used to identify whether there is an MC4 head wire nose in the card slot, and the second optical coupler is used to identify whether the direction of the MC4 head wire nose is consistent with the required direction.

[0011] In a preferred embodiment of the present invention, the conveyor belt is driven to rotate by a belt motor, and the MC4 head lug is conveyed outward through the conveyor belt to the next process for retrieval and use.

[0012] In a preferred embodiment of the present invention, the rotating adjustment disk is driven to rotate by a rotary motor. The rotating adjustment disk is located above the conveyor belt and can move vertically. An electromagnet for cooperating with the rotating adjustment disk is located below the conveyor belt. The rotating adjustment disk contains an armature. When the direction of the MC4 head wire nose is opposite to the required direction, the electromagnet works, attracts the rotating adjustment disk down, and is driven by the rotary motor to rotate 180 degrees, adjusting the direction of the MC4 head wire nose to the required direction.

[0013] In a preferred embodiment of the present invention, a third optical coupler is provided below the orthographic projection of the rotating adjustment disk on the conveyor belt. The third optical coupler is used for positioning to determine that the MC4 head wire nose is located below the rotating adjustment disk so that the rotating adjustment disk can perform the corresponding work.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The technical solution of this utility model, through the structure of a hopper and a mixing wheel, allows the MC4 head wire nose in the hopper to fall from the outlet of the hopper under the action of the mixing wheel, facilitating subsequent work; through the structure of two slots on the feeding roller, the MC4 head wire nose is received through the slots, with one slot at the top receiving the MC4 head wire nose while the other slot is at the bottom, so that the received MC4 head wire nose falls onto the conveyor belt; through the structure of a rotating adjustment plate, the direction of the MC4 head wire nose can be adjusted to the required direction for direct handling and use.

Detailed Implementation

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model will be described in detail below. Example 1

[0021] like Figure 1-3 As shown, this utility model is an automatic continuous sorting device for MC4 head nose, including a hopper 1, a stirring wheel 2, a feeding wheel 4, a conveyor belt 8, and a rotating adjustment disc 10.

[0022] like Figure 1 and Figure 2 As shown, hopper 1 is used to hold MC4 head lugs. hopper 1 can be supported by a bracket and placed directly on the ground. The lower part of hopper 1 is the outlet. It should be noted that the width b of the hopper outlet is the same as the length of the MC4 head lug, so only one MC4 head lug can pass through the outlet of hopper 1 at a time.

[0023] In this embodiment, an agitator 2 is installed inside the hopper 1. The agitator 2 is driven by an agitator motor 3 to prevent the MC4 head wire nose from becoming blocked at the outlet of the hopper 1, which would prevent the MC4 head wire nose from falling into the feed roller 4 and affect the normal operation of subsequent work.

[0024] In this embodiment, the stirring motor 3 can be fixed to the outer wall of the hopper 1 by bolts or other means. The motor shaft of the stirring motor 3 extends into the interior of the hopper 1 and is connected to the stirring wheel 2. The stirring motor 3 can drive the stirring wheel 2 to rotate.

[0025] Furthermore, the mixing wheel 2 preferably has a petal-shaped cross-section, so the edge of the mixing wheel 2 is uneven, which can better mix and avoid clogging of the MC4 head nose. At the same time, the concave part of the edge of the mixing wheel 2 can just accommodate one MC4 head nose. By cooperating with the outlet of the hopper 1, it can be ensured that when the mixing wheel 2 rotates, only one MC4 head nose falls from the outlet of the hopper 1 at a time.

[0026] like Figure 1 and Figure 3 As shown, the feeding wheel 4 is installed below the hopper 1. The specific installation method is as follows: the rotating shaft of the feeding wheel 4 is connected to the bracket of the hopper 1, the feeding motor 5 is fixed to the bracket by bolts, and the motor shaft of the feeding motor 5 is connected to the rotating shaft of the feeding wheel 4. Therefore, the feeding wheel 4 can be rotated by the feeding motor 5.

[0027] In this embodiment, the feeding roller 4 is located directly below the outlet of the hopper 1. Two slots 6 are formed on the feeding roller 4 by indentation. The slots 6 are used to receive MC4 head wire noses that fall from the hopper. The two slots 6 are symmetrical to each other and are distributed at 180 degrees on both sides of the feeding roller 4. When the feeding roller 4 rotates, one of the slots 6 rotates to the top and is located directly below the outlet of the hopper 1. An MC4 head wire nose falls from the hopper 1 and enters the slot 6. As the feeding roller 4 continues to rotate, the slot 6 containing the MC4 head wire nose moves to the bottom and the MC4 head wire nose falls from it and lands above the conveyor belt 8. At the same time, the other slot 6 rotates to the top. This is one cycle. By repeating this process, the transfer of MC4 head wire noses can be continuously achieved.

[0028] In this embodiment, the slot 6 can only accommodate one MC4 head wire nose. In order to prevent the MC4 head wire nose from accidentally falling off when the feed roller 4 is rotated to the bottom, an outer cover 7 is provided on the outside of the feed roller 4. The outer cover 7 is circular and is connected to the bracket to wrap around the outside of the feed roller 4.

[0029] Furthermore, the depth of the slot 6 is sufficient to accommodate one MC4 wire nose. Alternatively, the slot 6 can be further recessed to form a matching groove based on the shape of the MC4 wire nose. This would make the MC4 wire nose more stable when it enters the slot 6, preventing it from wobbling during the rotation of the feed roller 4. Since the orientation of the MC4 wire nose cannot be determined by which side its thicker end is located within the slot, the grooves in the slot 6 need to be symmetrically arranged, with space on both sides to accommodate the thicker end of the MC4 wire nose. Regardless of the orientation of the MC4 wire nose as it enters the slot 6, the grooves can further engage and position it, preventing wobbling.

[0030] In this embodiment, the top and bottom of the outer cover 7 are open. The slot 6 has the same size and specifications as the opening of the outer cover 7. The top opening is located directly below the outlet of the hopper 1. When the slot 6 rotates to the opening, the MC4 head wire nose can enter the slot 6 through the opening. As the feed roller 4 continues to rotate, the MC4 head wire nose will not fall out of the slot 6 due to the obstruction of the outer cover 7.

[0031] Furthermore, when the slot 6 is rotated to the bottom, the slot 6 coincides with the bottom opening of the outer cover 7, allowing the MC4 head wire nose to fall from the slot 6 through the opening onto the conveyor belt 8 below.

[0032] In this embodiment, the outer cover 7 is fixedly connected to the first optocoupler 13 and the second optocoupler 14 at the upper and lower openings respectively. The first optocoupler 13 and the second optocoupler 14 are both existing technologies.

[0033] In this embodiment, the first optocoupler 13 is located at the top opening of the outer cover 7 and is used to identify whether there is an MC4 head wire nose in the top slot 6. When no MC4 head wire nose is detected, the stirring motor 3 starts to work, the stirring wheel 2 rotates, and the MC4 head wire nose in the hopper 1 falls into the slot 6.

[0034] Furthermore, when the first optocoupler 13 detects the presence of an MC4 head wire nose in the uppermost slot 6, the feeding motor 5 starts working and rotates 180 degrees, the feeding wheel 4 rotates 180 degrees accordingly, the slot 6 gradually moves to the lowermost position, and then the MC4 head wire nose falls onto the conveyor belt 8 through the opening of the outer cover 7.

[0035] In this embodiment, the second optocoupler 14 is used to identify whether the direction of the MC4 head nose is consistent with the required direction. When the direction of the MC4 head nose is consistent with the required direction, it can be directly conveyed out through the conveyor belt 8. When the direction of the MC4 head nose is inconsistent with the required direction, it needs to be adjusted by rotating the adjustment disk 10 before being conveyed out for subsequent use.

[0036] Furthermore, the gap between the feed roller 4, the hopper 1, and the conveyor belt 8 is very small, so the MC4 head wire nose will not fall out of the gap when it is transferred through the feed roller 4.

[0037] In this embodiment, the conveyor belt 8 is driven by the belt motor 9, which is the prior art. The conveyor belt 8 can be directly placed on the ground by support, or fixed to the support frame of the hopper 1.

[0038] In this embodiment, the rotating adjustment disk 10 is used to adjust the direction of the MC4 head nose. When the MC4 head nose is transferred by the feed roller 4, there are only two possibilities for the direction of the MC4 head nose: one is the required direction, and the other is the opposite of the required direction. When the second optocoupler 14 detects that the direction of the MC4 head nose is opposite to the required direction, the rotating adjustment disk 10 needs to be operated. By rotating the adjustment disk 10, the MC4 head nose is rotated 180 degrees and the direction is consistent with the required direction, so as to facilitate subsequent use.

[0039] In this embodiment, the rotating adjustment disk 10 is connected to the motor shaft of the rotating motor 11. Driven by the rotating motor 11, it can rotate in the horizontal direction so that the MC4 head wire nose, which is in the opposite direction, can rotate 180 degrees to match the required direction for subsequent use.

[0040] In this embodiment, the rotating adjustment disk 10 is parallel to the belt surface of the conveyor belt 8, and the side of the rotating adjustment disk 10 that is in contact with the belt surface forms a positioning groove that wraps around the MC4 head wire nose through the inward concavity. The positioning groove wraps around and covers the MC4 head wire nose. Then, the rotating adjustment disk 10 rotates 180 degrees, which can drive the MC4 head wire nose to rotate 180 degrees as well, thereby realizing the 180-degree adjustment of the MC4 head wire nose direction.

[0041] In this embodiment, the rotating adjustment disk 10 and the rotating motor 11 are integrated. The specific installation can be carried out in the following way: a guide rod is fixed by the edge of the conveyor belt 8. The guide rod is vertical and will not move. The motor seat of the rotating motor 11 is slidably connected to the guide rod. Therefore, the rotating adjustment disk 10 can move up and down in the vertical direction, thereby achieving the purpose of adjusting the direction of the MC4 head wire nose.

[0042] Furthermore, a pressure spring is also fitted on the guide rod. The two ends of the pressure spring are respectively attached to the edge of the conveyor belt 8 and the motor base of the rotary motor 11. Therefore, when the rotary motor 11 is driven by an external force to move the rotary adjustment disk 10 downward, the pressure spring is compressed. When the external force is removed, the rotary motor 11 moves upward under the action of the pressure spring, driving the rotary adjustment disk 10 back to the initial position, so as to facilitate subsequent continuous work.

[0043] In this embodiment, an electromagnet 12 is installed below the belt surface of the conveyor belt 8 and directly below the rotating adjustment disk 10. The electromagnet 12 can be fixed in the following way: it is fixed to the two sides of the conveyor belt 8 by the two ends of the connecting rod. The electromagnet 12 is installed in the middle of the connecting rod. The rotating adjustment disk 10 is made of an armature. When the electromagnet 12 works, it can generate a downward attraction force on the rotating adjustment disk 10, causing it to move downward and cover the outside of the MC4 head wire nose. When the electromagnet 12 stops working, the attraction force disappears, and the rotating adjustment disk 10 will return to its initial position.

[0044] In this embodiment, the conveyor belt 8 is provided with a third optocoupler 15 for positioning the MC4 head wire nose. The third optocoupler 15 is located directly below the rotary adjustment disk 10. Specifically, the third optocoupler 15 can be installed on both sides of the conveyor belt 8, perpendicular to the movement direction of the conveyor belt 8. When the belt surface of the conveyor belt 8 moves, it drives the MC4 head wire nose to move until the MC4 head wire nose enters the detection range of the third optocoupler 15. At this point, the conveyor belt 8 stops conveying, and the rotary adjustment disk 10 enters the working state, which can adjust the direction of the MC4 head wire nose to make its direction meet the requirements.

[0045] Furthermore, when the rotating adjustment disc 10 is rotated downwards, it only needs to remain in contact with the MC4 head wire nose and be able to drive the MC4 head wire nose to rotate together; it does not need to be completely in contact with the belt surface of the conveyor belt 8.

[0046] An automatic continuous sorting device for MC4 head thread nose in this embodiment is as follows:

[0047] After the device is started, the first optocoupler 13 detects whether there is an MC4 head wire nose in the uppermost slot 6. If not, the stirring motor 3 drives the stirring wheel 2 to rotate, and an MC4 head wire nose falls from the hopper 1, entering the slot 6 through the opening of the outer cover 7. Then, the feeding motor 5 rotates, and the slot 6 moves accordingly until the slot 6 moves to the bottom. At this time, the MC4 head wire nose falls onto the conveyor belt 8 through the opening of the outer cover 7. At this time, the second optocoupler 14 identifies the MC4 head wire nose and determines its direction. If the direction of the MC4 head wire nose is inconsistent with the required direction, the device will detect the MC4 head wire nose. The direction needs to be adjusted by rotating the adjustment plate 10. The MC4 head wire nose is conveyed outward by the conveyor belt 8 until it enters the detection range of the third optocoupler 15. At this time, the conveyor belt 8 stops working, the electromagnet 12 works, and the rotating adjustment plate 10 is pulled down, so that it adheres to and wraps around the MC4 head wire nose. Then the rotating motor 11 works and rotates 180 degrees to adjust the direction of the MC4 head wire nose by 180 degrees so that its direction is the required direction. Then the electromagnet 12 stops working, the rotating adjustment plate 10 returns to its original position, and finally the MC4 head wire nose is conveyed out by the conveyor belt 8.

[0048] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
