[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0034] Example 1, as Figure 1-2 shown, an electronic component SMT device includes a PCB conveyor belt 1. A connecting seat 11 is fixedly connected to the right side of the PCB conveyor belt 1. An electronic component conveyor belt 12 is arranged at the upper end of the connecting seat 11. Both the PCB conveyor belt 1 and the electronic component conveyor belt 12 are provided with conveyor rollers. A swing assembly 2 is arranged at the rear side of the PCB conveyor belt 1. A SMT component 3 is arranged at the front side of the swing assembly 2. A transport assembly 4 is arranged on the right side of the PCB conveyor belt 1. Positioning assemblies 5 are symmetrically arranged at the upper end of the PCB conveyor belt 1. A pressing assembly 6 is arranged at the front side of the positioning assembly 5. A cleaning assembly 7 is arranged at the rear side of the positioning assembly 5.

[0035] Therefore, through the cooperation of each component in this solution, during the process of the SMT component 3 following the swing of the swing assembly 2, the intermittent movement of the PCB conveyor belt 1 and the electronic component conveyor belt 12 can be realized, achieving the effect of reducing waiting time, avoiding mutual interference and improving work continuity. At the same time, the precise positioning of the PCB board is realized, ensuring that the PCB board can be in an accurate intermediate position at the moment of SMT, and the electronic components can be accurately mounted on the target position of the PCB board. At the same time, the PCB board can be pressed and the mounting head 32 can be cleaned, ensuring the accuracy and reliability of SMT, and maintaining the good adsorption performance of the mounting head 32. The components of the whole are closely matched, effectively improving the SMT quality and production stability, and reducing the production defect rate.

[0036] Embodiment 2. On the basis of Embodiment 1, this embodiment is to achieve the effects of intermittent movement of the PCB conveyor belt 1 and the electronic component conveyor belt 12 and precise positioning of the PCB board.

[0037] Referring to Figure 1-8 , the swinging assembly 2 includes a fixed seat 21 fixedly connected to the rear side of the upper end of the PCB conveyor belt 1. A hydraulic device 22 is fixedly installed at the bottom end of the fixed seat 21. The output end of the hydraulic device 22 is fixedly connected to a sliding seat 23. A limiting seat 24 is fixedly connected to the outer surface of the sliding seat 23. A lifting seat 25 is rotatably connected to the lower end of the limiting seat 24. An arc-shaped groove 251 is formed on the outer surface of the lifting seat 25. A fixed block 26 is fixedly connected to the upper end of the PCB conveyor belt 1. A limiting rod 27 is rotatably connected to the outer surface of the fixed block 26. The outer surface of the limiting rod 27 is slidably connected to the arc-shaped groove 251.

[0038] Among them, the arc-shaped groove 251 is composed of a vertical part and an arc part. When the whole lifting seat 25 rises and the arc surface of the arc-shaped groove 251 contacts the limiting rod 27, the lifting seat 25 will rotate to the right.

[0039] Start the hydraulic device 22 to push the sliding seat 23 and the limiting seat 24 to move upward as a whole. During the moving process, the limiting rod 27 is always slidably connected to the arc-shaped groove 251. When the limiting rod 27 contacts the arc part of the arc-shaped groove 251, the lifting seat 25 will rotate during the continuous upward movement, so that the whole patch assembly 3 swings directly above the electronic component conveyor belt 12.

[0040] Referring to Figure 3 And Figure 4 , the patch assembly 3 includes a connecting frame 31 fixedly connected to the outer surface of the lifting seat 25. A mounting head 32 is fixedly installed at the end of the connecting frame 31 away from the lifting seat 25.

[0041] The above-mentioned mounting head 32 is a conventional technical means in the prior art. The mounting head 32 is responsible for accurately mounting electronic components on the printed circuit board PCB. It uses the same tool for material taking and patching. The working principle is as follows:

[0042] When taking materials, the mounting head 32 moves above the electronic component conveyor belt 12, and the adsorption tool on the mounting head 32 is aligned with the electronic component. At this time, the negative pressure system inside the adsorption tool is started, and a negative pressure is quickly formed between the contact surface of the component and the adsorption tool, and the component is firmly adsorbed by using the atmospheric pressure difference to complete the material taking action.

[0043] After the adsorption component, the placement head 32 conducts a comprehensive inspection of the component through a high-precision vision system to ensure that the model, direction, and position of the component are accurate. Subsequently, the placement head 32 moves above the pad position corresponding to the PCB conveyor belt 1. Then, the negative pressure system slowly releases the pressure, enabling the component to be accurately placed on the PCB pad under the action of gravity and a small force, completing the chip placement process.

[0044] Refer to Figure 4 、 Figure 5 And Figure 6 As shown in FIGS. 1 and 2, the transportation assembly 4 includes a first fixing frame 41 fixedly connected to the lower side of the front end of the fixing base 21. The upper end of the middle position of the first fixing frame 41 is rotatably connected to a rotating slider 43. The outer surface of the rotating slider 43 is slidably connected to the lifting seat 25. The lower side of the outer surface of the rotating slider 43 is fixedly connected to a first pulley transmission group 44. The lower end of the side of the first pulley transmission group 44 away from the rotating slider 43 is fixedly connected to a first rotating shaft 45. A first bevel gear 46 is fixedly connected to the outer surface of the first rotating shaft 45.

[0045] Specifically, the first pulley transmission group 44 is composed of two pulleys with different diameters and a belt. Among them, the pulley connected to the first rotating shaft 45 rotates faster. The stroke of the lifting seat 25 driving the chip placement assembly 3 to swing directly above the electronic component conveyor belt 12 is equal to the stroke of the next PCB board on the surface of the PCB conveyor belt 1 moving to the designated position. Similarly, the stroke of the lifting seat 25 driving the chip placement assembly 3 to swing directly above the PCB conveyor belt 1 is equal to the stroke of the next electronic component on the surface of the electronic component conveyor belt 12 moving to the designated position.

[0046] During the rotation of the lifting seat 25, it will drive the rotating slider 43, the first pulley transmission group 44, and the first rotating shaft 45 to rotate together, and the lifting seat 25 can also slide up and down on the outer surface of the ratchet 48.

[0047] On both sides of the outer surface of the first bevel gear 46, second bevel gears 47 are symmetrically engaged. The inner surfaces of the two second bevel gears 47 are both rotatably connected to ratchets 48. One end of each of the two ratchets 48 away from each other is fixedly connected to a second rotating shaft 49. The left end of the left second rotating shaft 49 is fixedly connected to the conveyor roller of the PCB conveyor belt 1. A second transmission pulley belt group 410 is fixedly connected to the outer surface of the right second rotating shaft 49. One end of the second transmission pulley belt group 410 away from the second rotating shaft 49 is fixedly connected to a third rotating shaft 411. The third rotating shaft 411 is fixedly connected to the conveyor roller of the electronic component conveyor belt 12.

[0048] Furthermore, the second transmission pulley belt group 410 is composed of two pulleys with the same diameter and a belt.

[0049] Among them, in accordance with Figure 6In the orientation, the ratchet 48 includes a pawl. When the lifting seat 25 drives the patch component 3 to swing counterclockwise as a whole, the first bevel gear 46 will rotate counterclockwise together with the first pulley transmission group 44 and the first rotating shaft 45. As a result, the second bevel gear 47 on the left engages with the first bevel gear 46 and rotates counterclockwise, driving the pawl to move. At this time, the pawl slides on the tooth back of the ratchet 48 that matches the second bevel gear 47 on the left. When it reaches the tooth root, it is embedded in the ratchet tooth groove, pushing the ratchet 48 to rotate counterclockwise together, driving the second rotating shaft 49 on the left to rotate, so that the PCB conveyor belt 1 moves forward a part towards the front end. When the patch component 3 finishes picking up the electronic components and rotates clockwise back with the lifting seat 25, the first bevel gear 46 rotates clockwise together with the first pulley transmission group 44 and the first rotating shaft 45. The pawl slides over the tooth back of the ratchet 48. The ratchet 48 on the left and the rotating shaft 49 are both stationary. At this time, the PCB conveyor belt 1 remains stationary;

[0050] On the contrary, the second bevel gear 47 on the right, the ratchet 48 and the second bevel gear 47 on the left, the ratchet 48 are symmetrically arranged. Therefore, when the lifting seat 25 drives the patch component 3 to swing counterclockwise as a whole, driving the first bevel gear 46 to rotate counterclockwise together with the first pulley transmission group 44 and the first rotating shaft 45, the second bevel gear 47 on the right will rotate clockwise. At this time, the pawl slides over the tooth back of the ratchet 48 on the right. At this time, the ratchet 48 on the right and the rotating shaft 49 are stationary, and the electronic component conveyor belt 12 on the right remains stationary. When the mounting head 32 finishes picking up the electronic components and returns, it will drive the rotating slider 43, the first pulley transmission group 44, the first rotating shaft 45 and the first bevel gear 46 to rotate clockwise together. The first bevel gear 46 will drive the second bevel gear 47 on the right to rotate counterclockwise. The second bevel gear 47 on the right drives the pawl to move. At this time, the pawl slides on the tooth back of the ratchet 48 that matches the second bevel gear 47 on the right. When it reaches the tooth root, it is embedded in the ratchet tooth groove, pushing the ratchet 48 to rotate counterclockwise together, driving the second rotating shaft 49 on the right to rotate counterclockwise, so that the electronic component conveyor belt 12 moves forward a part towards the front end;

[0051] That is to say, when the connecting frame 31 and the mounting head 32 move above the electronic component conveyor belt 12, the PCB conveyor belt 1 will move forward as a whole by a section, and the electronic component conveyor belt 12 remains stationary. When the mounting head 32 finishes picking up the electronic components and returns, the PCB conveyor belt 1 remains stationary, and the electronic component conveyor belt 12 moves forward by a section, reducing the overall waiting time, increasing the running coherence, and avoiding the problem of mutual interference.

[0052] Refer to Figure 7 And Figure 8 As shown in, the positioning component 5 includes a lifting frame 51 fixedly connected to the right side of the front end of the sliding seat 23. The lower end of the lifting frame 51 is fixedly connected with a pressing block 52. The right side of the upper end of the PCB conveyor belt 1 is fixedly connected with an airbag 53. The lower end of the pressing block 52 is fixedly connected with the airbag 53.

[0053] On the right side of the upper end of the PCB conveyor belt 1, there is a fixed connection with an outer housing 54. An air bag two 55 is arranged on the inner surface of the outer housing 54. At the front end of the air bag two 55, there is an air pipe 56. The front end of the air pipe 56 is fixedly connected with the air bag one 53. On the left side of the outer housing 54, there are two springs one 57 fixedly connected. The left ends of the two springs one 57 are jointly fixedly connected with a limiting plate 58.

[0054] Among them, the outer housing 54 can provide a limit for the air bag two 55, so that the air bag two 55 cannot expand from other positions.

[0055] When the hydraulic device 22 pushes the sliding seat 23, the limiting seat 24 and the lifting seat 25 to descend together, it drives the whole patch component 3 to descend. As a result, the lifting frame 51 follows and descends together. During the descent of the lifting frame 51, it drives the pressing block 52 to squeeze the air bag one 53. The air bag one 53 will transport the gas to the air bag two 55 under extrusion, causing the air bag two 55 to expand and move against the limiting plate 58, so as to limit the pcb board on the surface of the PCB conveyor belt 1, enabling the electronic components to be accurately mounted on the target position of the PCB board, and ensuring that it will not deviate from its position due to the slight shaking of the conveyor belt or other external forces during the patching process.

[0056] Moreover, when the hydraulic device 22 drives the sliding seat 23, the limiting seat 24 and the lifting seat 25 to start raising at the beginning, the limiting rod 27 moves in the vertical part of the arc-shaped groove 251. At this time, the lifting seat 25 will not rotate. Therefore, during this rising distance, the pressing block 52 will pull the air bag one 53 to become larger, the air pressure inside the air bag one 53 changes, the gas in the air bag two 55 will return to the air bag one 53, the air bag two 55 becomes smaller, and the limiting plate 58 loses the extrusion and resets, thus unlocking the limit on the PCB board. Then the lifting seat 25 drives the patch component 3 to rotate. Synchronously, the PCB conveyor belt 1 will move, and there will be no conflict with the patch component 3.

[0057] Refer to Figure 7 As shown in the figure, the pressing component 6 includes a connecting plate 61 fixedly connected to the front side of the lower end of the pressing block 52. There are two 62 at the lower end of the connecting plate 61. The lower ends of the two 62 are jointly fixedly connected with a pressing plate 63.

[0058] The above-mentioned pressing plate 63 can press the patched pcb board, enhancing the connection firmness between the patched components and the PCB board, and improving the reliability and stability of the product.

[0059] Therefore, through the cooperation among the swinging component 2, the patch component 3, and the transportation component 4, this solution can intermittently drive the PCB conveyor belt 1 and the electronic component conveyor belt 12 to move, advance the new PCB board or electronic components to be patched to the appropriate positions in advance, prepare for the subsequent patching, reduce the waiting time, and during the downward movement for patching, the airbag one 53 and the airbag two 55 in the positioning component 5 can be used to push the limiting plate 58 to limit the PCB board, so that the electronic components can be accurately mounted on the target positions of the PCB board, ensuring that they will not shift in position due to the slight shaking of the conveyor belt or other external forces during the patching process, and enhancing the connection firmness between the patched components and the PCB board through the pressing component 6, improving the overall working efficiency.

[0060] Embodiment 3. On the basis of Embodiments 1 and 2, this embodiment aims to achieve the effect of repeatedly cleaning the mounting head 32.

[0061] Refer to Figure 1 、 Figure 2 、and 9 and Figure 10 As shown in, the cleaning component 7 includes a second fixing frame 71 fixedly connected to the upper end of the PCB conveyor belt 1. Two second springs 72 are fixedly connected to the front end of the second fixing frame 71. A regulating seat 73 is fixedly connected to the front ends of the two second springs 72. A sliding groove 731 is opened at the upper end of the regulating seat 73. A cleaning brush 74 is arranged at the front end of the regulating seat 73.

[0062] Refer to Figure 10 As shown in, a pressing rod 75 is fixedly connected to the lower end of the connecting frame 31. The outer surface of the pressing rod 75 is slidably connected to the sliding groove 731. The outer surface of the cleaning brush 74 is movably connected to the mounting head 32.

[0063] Specifically, the upper end of the above-mentioned regulating seat 73 is an inclined surface. When the pressing rod 75 follows the connecting frame 31 to descend, the pressing rod 75 will slide on the surface of the sliding groove 731, thereby squeezing the regulating seat 73 to drive the cleaning brush 74 to retreat. During the retreating process, the cleaning brush 74 will contact the mounting head 32 adsorbed with electronic components, thereby cleaning the dust on the surface of the electronic components.

[0064] Similarly, when the mounting head 32 rises, the pressing rod 75 will gradually separate from the sliding groove 731, and the regulating seat 73 will slowly move forward without being squeezed, thereby cleaning the suction ports on the surface of the mounting head 32.

[0065] During the frequent suction of electronic components by the mounting head 32, the suction ports are prone to adsorb pollutants such as dust and impurities. These pollutants may affect the adsorption performance of the mounting head 32, resulting in unstable component suction or inaccurate patching positions. The reciprocating cleaning of the cleaning brush 74 can timely remove these pollutants, enabling the mounting head 32 to always maintain a good working state.

[0066] Therefore, in this solution, the cleaning component 7 is arranged on the lifting route of the chip component 3. When the chip component 3 passes by, the cleaning brush 74 can clean the suction ports on the surface of the placement head 32 and the adsorbed electronic components, timely remove pollutants, keep the placement head 32 in a good working state all the time, ensure the success rate of each chip placement operation, and effectively reduce the chip placement defects caused by the pollution of the placement head 32.
