Description

Technical Field

[0001] The utility model belongs to the technical field of solar photovoltaic panels, and more specifically, relates to a busbar cutting and bending mechanism. Background Art

[0002] The busbar is a key component in a solar photovoltaic panel. It is usually made of a metal material with high conductivity and is used to connect multiple solar cells in series or parallel to form a battery string or battery pack so that the generated electricity can be collected and transmitted in a centralized manner. During production, the busbar material is usually cut and bent by a cutting and bending machine. Existing busbar cutting and bending machines usually consist of a feeding mechanism for placing and flattening the busbar material, a gripping mechanism for clamping the busbar and moving it, two sets of placing and bending mechanisms for placing the cut busbar or bending the cut busbar, and a cutting mechanism for cutting the busbar.

[0003] Based on the above, in the operation process of the busbar cutting and bending machine, in order to ensure that the grasping mechanism can smoothly and accurately capture the busbar, the design of the cutting mechanism often leaves enough space on the left side of the upper and lower cutting knives. The original intention of this design is to avoid physical interference. However, when the end of the busbar is cut and separated by the cutting knife, due to the lack of immediate support or receiving mechanism, the cut part will fall rapidly, which may cause the overall position of the cut busbar to shift. This unpredictable displacement undoubtedly increases the difficulty and uncertainty of grasping for the subsequent stringer suction cup that relies on precise positioning, which may affect the smoothness and product quality of the entire production line. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a busbar cutting and bending mechanism to solve the existing operation process of the busbar cutting and bending machine. In order to ensure that the grasping mechanism can smoothly and accurately capture the busbar, the design of the cutting mechanism often leaves enough space on the left side of the upper and lower cutting knives. The original intention of this design is to avoid physical interference. However, when the end of the busbar is cut and separated by the cutting knife, due to the lack of immediate support or receiving mechanism, the cut-off part will fall rapidly, which may cause the overall position of the cut busbar to shift.

[0019] A lower connecting piece, wherein the lower connecting piece is fixedly connected to the mounting plate;

[0020] A lower cutting knife, wherein the lower cutting knife is fixedly connected to the lower connecting member;

[0021] A transmission rack is fixedly connected below the connecting bent rod.

[0022] Furthermore, the auxiliary cutting component also includes:

[0023] A transmission box, the transmission box being fixedly connected to the interior of the cutting mechanism;

[0024] A transmission shaft, the transmission shaft being rotatably connected to the interior of the transmission box;

[0025] A transmission gear is coaxially fixedly connected to the front end of the transmission shaft, and the transmission gear is meshed with the transmission rack.

[0026] Furthermore, the auxiliary cutting component also includes:

[0027] A swing lever, the right end of which is fixedly connected to the outside of the transmission shaft;

[0028] A limiting groove is provided inside the swing rod;

[0029] A sliding rod, the right end of which is slidably connected to the interior of the lower connecting member;

After the cutting is completed, the cutting cylinder drives the upper cutting knife to rise and the contact plate to drop synchronously, reserving space for the subsequent gripping mechanism, ensuring the efficient and continuous cutting process and realizing smooth operation of busbar cutting.

[0042] Secondly, during busbar cutting, in order to prevent the busbar from being lifted up due to molecular attraction or tool blunting, an anti-displacement component is designed. During cutting, the lower pressure plate contacts the busbar, and the anti-offside plate causes the connecting spring to contract. After the cutting is completed, when the upper connecting piece rises, the connecting spring temporarily leaves the pressure plate in place to jam the busbar that may move. Subsequently, the spring releases its force, and the lower pressure plate resets with the upper connecting piece, ensuring accurate cutting and stable busbar, thus achieving efficient cyclic cutting.

[0043] The utility model discloses that when the cutting cylinder drives the upper cutting knife and the lower cutting knife to cooperate to cut the bus bar, multiple components are linked to prevent the bus bar from falling and causing displacement when it is cut. At the same time, the anti-displacement component works together with the connecting spring through the lower pressure plate to effectively prevent the bus bar from being lifted up during cutting, ensuring accurate and stable cutting, providing good conditions for the subsequent suction cup to grab the bus bar for welding, and realizing a smooth cycle operation of bus bar cutting.

[0054] Example 1:

[0055] As attached Figure 1 To the attached Figure 7 As shown:

[0060] The cutting mechanism 5 is provided with two groups, and the two groups of cutting mechanisms 5 are separately fixedly connected to the cutting machine body 1;

[0061] Cutting cylinder 501, two cutting cylinders 501 are provided, and the two cutting cylinders 501 are fixedly connected to the inside of the two cutting mechanisms 5;

[0062] The upper connecting member 502 is provided with two pieces, and the two upper connecting members 502 are respectively fixedly connected to the bottom of the two cutting cylinders 501;

[0063] The upper cutting blade 503 is provided with two pieces, and the two upper cutting blades 503 are fixedly connected to the bottom of the upper connecting member 502 respectively;

[0064] Connecting bent rod 7, which is fixedly connected to the front of the upper connecting member 502;

[0065] Auxiliary cutting components: two groups of auxiliary cutting components are provided, and the two groups of auxiliary cutting components are respectively provided inside the two groups of cutting mechanisms 5.

[0066] Among them, the auxiliary cutting components include:

[0067] A mounting plate 6, the mounting plate 6 is fixedly connected to the inside of the cutting mechanism 5;

[0068] The lower connecting member 601 is fixedly connected to the mounting plate 6;

[0069] The lower cutting blade 602 is fixedly connected to the lower connecting member 601;

[0070] The transmission rack 701 is fixedly connected to the bottom of the connecting bent rod 7. Its function is that when the cutting cylinder 501 drives the upper connecting member 502 and the upper cutting knife 503 to move downward and cooperate with the lower cutting knife 602 to cut the bus bar, the connecting bent rod 7 and the transmission rack 701 move downward synchronously.

[0071] Among them, the auxiliary cutting components also include:

[0072] A transmission box 8 is fixedly connected to the inside of the cutting mechanism 5;

[0073] A transmission shaft 9 is rotatably connected to the interior of the transmission box 8;

[0074] Transmission gear 901, transmission gear 901 is coaxially fixedly connected to the front end of the transmission shaft 9, and the transmission gear 901 is engaged with the transmission rack 701. The effect brought about is that when the transmission rack 701 moves downward, it will drive the transmission shaft 9 to rotate through the gear rack transmission mechanism formed together with the transmission gear 901.

When the upper cutting knife 503 cooperates with the lower cutting knife 602 to cut the busbar, the resistance plate 1101 moves to be flush with the lower cutting knife 602, thereby catching the right end of the cut busbar to prevent its instantaneous falling and causing the overall displacement of the busbar.

[0082] The specific usage and function of this embodiment are as follows:

[0083] When the cutting cylinder 501 drives the upper connecting member 502 and the upper cutting knife 503 to move downward and cooperate with the lower cutting knife 602 to cut the bus bar, the connecting bending rod 7 and the transmission rack 701 will move downward synchronously, and the gear rack transmission mechanism composed of the transmission rack 701 and the transmission gear 901 will drive the transmission shaft 9 to rotate. The rotation of the transmission shaft 9 will drive the left end of the swing rod 10 to swing, thereby driving the contact plate through the cooperation of the internal limiting groove 1001, the limiting slider 1201, the connecting shaft 12 and the sliding rod 11. 1101 slides upward, and when the upper cutting knife 503 cooperates with the lower cutting knife 602 to cut the busbar, the contact plate 1101 moves to be flush with the lower cutting knife 602, thereby catching the right end of the cut busbar, preventing the overall displacement of the busbar caused by its instantaneous drop, resulting in deviation when the subsequent string welding machine suction cup grabs it; when the cutting cylinder 501 drives the upper cutting knife 503 to move upward, the contact plate 1101 moves downward, avoiding obstruction when the subsequent grabbing mechanism 3 moves to this position to grab the next part of the busbar.

[0084] Example 2:

[0085] Based on the first embodiment, as shown in the attached Figure 1 To the attached Figure 7 As shown, it also includes anti-displacement components, and two groups of anti-displacement components are provided. The two groups of anti-displacement components are respectively provided inside the two groups of cutting mechanisms 5.

[0086] Among them, the anti-displacement components include:

[0087] A fixing box 13 is fixedly connected to the bottom of the connecting bent rod 7;

[0088] A lower pressing rod 14 is slidably connected to the bottom of the fixing box 13;

[0089] The lower pressing plate 1402 is fixedly connected to the left side of the lower pressing rod 14. The effect is that when the cutting cylinder 501 drives the upper connecting member 502 to move downward, it will synchronously drive the fixed box 13, the lower pressing rod 14 and the lower pressing plate 1402 to move downward.

[0090] Among them, the anti-displacement components also include:

[0091] Connecting spring 1401, the bottom of connecting spring 1401 is fixedly connected to the upper surface of pressing rod 14, and the top of connecting spring 1401 is fixedly connected to the interior of fixing box 13;

[0092] The anti-offside plate 15 is fixedly connected to the top of the lower connecting member 601. Its function is that when the upper cutting knife 503 cooperates with the lower cutting knife 602 to cut the bus bar, the lower pressure plate 1402 contacts the upper surface of the bus bar, and at this time, under the obstruction of the anti-offside plate 15, the connecting spring 1401 contracts. When the cutting is completed and the upper connecting member 502 moves upward, under the action of the connecting spring 1401, the lower pressure rod 14 and the lower pressure plate 1402 will still stay in place for a moment, thereby blocking the bus bar lifted by the upper cutting knife 503 in its original position to prevent the bus bar from moving at will.

[0093] The specific usage and function of this embodiment are as follows:

[0094] When the upper cutting knife 503 comes into contact with the bus bar, it may generate attraction due to the action of the bus bar molecules, or the upper cutting knife 503 may be blunted, causing the upper cutting knife 503 to lift the bus bar during the upward movement. At this time, through the anti-displacement component, the cutting cylinder 501 drives the upper connecting piece 502 to move downward, which will simultaneously drive the fixing box 13, the lower pressure rod 14 and the lower pressure plate 1402 to move downward. When the upper cutting knife 503 cooperates with the lower cutting knife 602 to cut the bus bar, the lower pressure plate 1402 and the bus bar are cut off. The upper surface of the bus bar is in contact, and at this time, under the obstruction of the anti-offside plate 15, the connecting spring 1401 contracts. When the cutting is completed and the upper connecting piece 502 moves upward, under the action of the connecting spring 1401, the lower pressure rod 14 and the lower pressure plate 1402 will still stay in place for a moment, thereby blocking the bus bar lifted by the upper cutting knife 503 in its original position to prevent the bus bar from moving at will. After the force of the connecting spring 1401 is released, the lower pressure rod 14 and the lower pressure plate 1402 will continue to be driven to rise, which is convenient for continued recycling.
