[0002] In the manufacturing and operation of LED in-line wire bonding machines, accurate and stable wire payout is one of the key factors to ensure the quality of subsequent welding. For a long time, this field has generally adopted a swing-bar wire payout mechanism to achieve wire supply. The working principle of the swing-bar wire payout mechanism is to gradually pull the gold wire stored in the wire barrel out and supply it to the welding area through the up and down reciprocating motion of the mechanical swing bar. However, this traditional swing-bar wire payout method has obvious shortcomings.

[0003] This payoff method is passive, meaning the wire often appears bent or twisted, which directly affects the quality of subsequent bending and welding processes. Since the wire tension is difficult to stably control and can only move within the fixed range of the swing arm, it is difficult to meet the requirements of high-precision welding. Therefore, we have improved this problem and proposed an air-blowing payoff mechanism. Summary of the Invention

[0004] The utility model aims to solve the existing problem that when a gold wire is pulled out of a wire drum by the up and down swing of a swing rod, the wire is pulled crooked, which is not conducive to subsequent arc bending and welding.

[0029] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] As described in the background technology, a rocker-type wire-paying mechanism is used to realize the supply of gold wire. The working principle of the rocker-type wire-paying mechanism is to gradually pull out the gold wire stored in the wire barrel and supply it to the welding area through the up and down reciprocating motion of the mechanical rocker. However, this traditional rocker-type wire-paying method has obvious shortcomings. This wire-paying method is passive wire-paying, that is, the pulled-out gold wire is often in a bent or twisted state, which directly affects the subsequent arc bending and welding process quality. Since the gold wire tension is difficult to stably control and can only move within the fixed range of movement of the rocker, it is difficult to meet the needs of high-precision welding.

[0031] In order to solve this technical problem, the utility model provides an air-blowing wire-paying mechanism.

[0032] Specifically, please refer to Figure 2 、 Figure 4 and Figure 5 , the air-blowing pay-off mechanism specifically includes:

[0033] The blowing plate 5 has a blowing seat 7 installed on one side of the blowing plate 5. Two optical fiber sensors 6 are also connected to one side of the blowing plate 5. A gap is left between the two optical fiber sensors 6 for wiring. A cover plate 502 is also installed on one side of the blowing plate 5.

[0034] The utility model provides an air-blowing pay-off mechanism. The utility model provides an air-blowing plate 5, an optical fiber sensor 6 and an air-blowing seat 7. The air flow size of the air-blowing seat 7 is used to control the tension of the gold wire, so that the gold wire can maintain a stable straight line state under the action of the air-blowing plate 5 and move up and down within a fixed area. Compared with the traditional rocker-type pay-off, the utility model can effectively control the tension of the gold wire by precisely adjusting the air flow size, so that the gold wire can maintain a stable tension state during the pay-off process; under the action of the air-blowing plate 5, the gold wire can move smoothly along a preset trajectory, avoiding the problem of gold wire bending or twisting caused by the swing of the rocker in the traditional pay-off method; the air-blowing pay-off method allows the gold wire to move in a larger range, and is more flexible and adaptable than the rocker-type pay-off method.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0038] Example 1, please refer to Figure 2 、 Figure 4 and Figure 5The air filter 5 is a kind of air-blowing type pay-off mechanism, which includes an air blowing plate 5, a air blowing seat 7 installed on one side of the air blowing plate 5, and two optical fiber sensors 6 connected to one side of the air blowing plate 5. A gap for routing is left between the two optical fiber sensors 6, and a cover plate 502 is installed on one side of the air blowing plate 5. The two optical fiber sensors 6 are arranged one above and one below to form upper and lower limit positions. The present invention controls the tension of the gold wire by the air flow size of the air blowing seat 7 through the provided air blowing plate 5, the optical fiber sensor 6 and the air blowing seat 7, so that the gold wire can maintain a stable straight state under the action of the air blowing plate 5 and move up and down in a fixed area. Compared with the traditional pendulum type pay-off, the present invention can effectively control the tension of the gold wire by precisely adjusting the air flow size, so that the gold wire can maintain a stable tension state during the pay-off process. Under the action of the air blowing plate 5, the gold wire can move smoothly along the preset trajectory, avoiding the problem of gold wire bending or twisting caused by the swing of the pendulum in the traditional pay-off method. The air blowing pay-off method allows the gold wire to move in a larger range, and its flexibility and adaptability are stronger than the pendulum type pay-off method.

[0039] Precisely adjusting the airflow size to control the gold wire tension can ensure that the gold wire always maintains a stable tension state during the pay-off process, avoiding problems such as gold wire breakage or uneven pay-off due to uneven tension, and improving the quality and efficiency of pay-off. A stable tension state is crucial for the processing and use of gold wire. If the tension is uneven, the gold wire may break, deform, and other problems during the processing, affecting product quality. At the same time, precise control of tension can also improve the speed and stability of pay-off, reduce downtime and scrap rate in the production process, because the airflow size can be precisely adjusted according to actual needs, and can adapt to gold wires of different specifications and different pay-off environments, thereby achieving effective control of the gold wire tension. By adjusting the airflow size, the tension can be controlled according to factors such as the diameter and material of the gold wire, ensuring that the gold wire always maintains appropriate tension during the pay-off process, avoiding the adverse effects of excessive or insufficient tension on the gold wire.

[0040] Further, such as Figure 1-Figure 3 As shown, an adjusting connecting plate 10 is installed on the side of the blowing plate 5 away from the cover plate 502, and a first mounting plate 108 is connected to the side of the adjusting connecting plate 10 away from the blowing plate 5. The adjusting connecting plate 10 and the first mounting plate 108 are used together to provide mounting support for the blowing plate 5. The adjusting connecting plate 10 and the first mounting plate 108 provide stable mounting support for the blowing plate 5, ensuring that the blowing plate 5 will not shake or shift during the line-paying process, thereby improving the stability of the line-paying.

[0041] Further, such as Figure 4 and Figure 5As shown, a connecting nozzle 701 is provided on one side of the blowing seat 7, and a plurality of air outlet holes 702 connected to the connecting nozzle 701 are provided on the other side of the blowing seat 7. The air outlet holes 702 are used to connect the air supply pipe, and the air outlet holes 702 are used to blow air to form an airflow. The design of the connecting nozzle 701 and the air outlet holes 702 facilitates the connection of the air supply pipe to form a stable airflow, thereby providing a reliable air source for controlling the tension of the gold wire. This design makes the connection of the air supply pipe more convenient and quick, thereby improving production efficiency. At the same time, the multiple air outlet holes 702 can evenly blow out the airflow to ensure the control effect of the gold wire tension. In actual production, stable airflow is the key to controlling the tension of the gold wire. If the airflow is unstable, it may cause uneven tension of the gold wire, thereby affecting product quality.

[0042] The airflow size of the blowing seat 7 is used to adjust the tension of the gold wire, so that the gold wire moves from top to bottom on the blowing plate 5 and keeps moving repeatedly between the upper and lower limits of the two optical fiber sensors 6; by adjusting the tension of the gold wire by the airflow size and making it move repeatedly between the upper and lower limits, the accuracy and stability of the wire pay-off are further improved. This movement mode can make the gold wire always move within a controllable range, avoiding excessive deviation or unstable movement of the gold wire. In actual production, precise tension control and stable movement can improve product quality and consistency.

[0043] Further, such as Figure 4 As shown, an air groove 501 is provided on one side of the air blowing plate 5 away from the adjusting connecting plate 10. The position of the air groove 501 corresponds to the position of the air outlet 702. The setting of the air groove 501 allows the airflow blown out of the connecting nozzle 701 to be discharged. The setting of the air groove 501 ensures that the airflow can be discharged smoothly, thereby improving the effect of the airflow on the gold wire. The smooth airflow can make the gold wire more stably maintain the preset position and tension state, thereby improving the accuracy and quality of the wire pay-off. In actual production, if the airflow is not discharged smoothly, it may cause airflow turbulence, affecting the tension control and position accuracy of the gold wire.

[0044] Further, such as Figure 1 and Figure 2 As shown, a fiber optic light blocking block 503 is provided on the side of the cover plate 502 away from the blowing plate 5. The fiber optic light blocking block 503 is used to block light for the fiber optic sensor 6, and can effectively block the interference of external light on the fiber optic sensor 6, thereby improving the detection accuracy of the fiber optic sensor 6. In actual production, external light may affect the normal operation of the fiber optic sensor 6, resulting in inaccurate detection results. The setting of the fiber optic light blocking block 503 can effectively block external light and ensure the detection accuracy of the fiber optic sensor 6.

[0045] Example 2, the air-blowing pay-off mechanism provided in Example 1 is further optimized, specifically, as follows Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown, a motor 101 is installed on the back of the first mounting plate 108, and the output shaft of the motor 101 is fixedly connected to a driving gear 104, which is engaged with a transmission gear 103. A transmission shaft 102 is fixedly inserted in the middle of the transmission gear 103, and one end of the transmission shaft 102 passes through the first mounting plate 108 and is fixedly connected to the spool seat 1. The motor 101 drives the spool seat 1 to rotate through gear transmission to realize automatic wire pay-off, thereby improving the efficiency and automation of wire pay-off. Automatic wire pay-off can reduce manual operation, reduce labor intensity, and improve production efficiency.

[0046] Further, such as Figure 1-Figure 3 As shown, the back of the first mounting plate 108 is connected to a fixed block 105, the top of the fixed block 105 is installed with a hinge 106, the hinge 106 is connected to a dust cover 107, the dust cover 107 is arranged on the top of the spool seat 1, the dust cover 107 is used to prevent dust from the gold spool, and the dust cover 107 is connected by the hinge 106 so that the dust cover 107 can be rotated open.

[0047] Example 3, the air-blowing pay-off mechanism provided in Example 1 or 2 is further optimized, specifically, as Figure 2 As shown, a wire pressing seat 4 is also provided on the motor 101, and the wire pressing seat 4 is used to fix the tail end of the gold wire to prevent the gold wire from loosening or falling off during the wire paying-out process, thereby improving the stability of the wire paying-out. In actual production, if the tail end of the gold wire is loose or falls off, it may cause the wire paying-out to be interrupted, affecting the production efficiency. The setting of the wire pressing seat 4 can effectively fix the tail end of the gold wire and ensure the smooth progress of the wire paying-out process.

[0048] Further, such as Figure 1 and Figure 2 As shown, a wire rod 3 is installed on the front of the first mounting plate 108. The wire rod 3 is located between the wire drum seat 1 and the adjustment connecting plate 10. The wire rod 3 is used to assist in the routing of the incoming wire. The wire rod 3 assists in the routing of the incoming wire, making the entry of the gold wire smoother.

[0049] Further, such as Figure 1 As shown, a second mounting plate 109 is installed on the back of the first mounting plate 108, and a fiber optic amplifier 8 is installed on the second mounting plate 109, and both fiber optic sensors 6 are connected to the fiber optic amplifier 8. The setting of the fiber optic amplifier 8 can amplify the signal of the fiber optic sensor 6 and improve the detection accuracy.

[0050] The use process of the air-blowing pay-off mechanism provided by the utility model is as follows:

[0051] For the convenience of description and understanding, this application uses A to represent the gold wire drum and B to represent the gold wire. The gold wire drum is installed on the wire drum seat 1, and the tail wire of the gold wire is connected to the wire pressing seat 4. The other end of the gold wire passes through the wire rod 3 and the two optical fiber sensors 6 and then passes between the blowing plate 5 and the cover plate 502. The tension of the gold wire can be adjusted by adjusting the airflow of the blowing seat 7. As the gold wire is used, the gold wire will move from top to bottom on the blowing plate 5. When the gold wire continues to move downward, it will pass through the lower limit of the optical fiber sensor 6. At this time, the wire drum seat 1 will rotate clockwise to release the gold wire. The gold wire will move upward along the blowing plate 5 under the action of the airflow. When the gold wire moves to the upper limit of the optical fiber sensor 6, the wire drum seat 1 will stop rotating, and finally ensure repeated movement between the upper and lower limits of the optical fiber sensor 6.
