However, the PCB is clamped by a pair of clamps in the existing technology, which directly presses on the edge of the PCB.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, an electronic component production placement machine described in an embodiment of the present invention includes a workbench 1; two pairs of symmetrically arranged conveyor belts 2 are installed on the top surface of the workbench 1; the top surface of the workbench 1 is rotatably connected to a rotating seat 3 on one side of the conveyor belt 2, and the rotating seat 3 is driven by a servo motor; the top surface of the rotating seat 3 is fixedly connected to an electric push rod 4; the top surface of the electric push rod 4 is fixedly connected to a support plate 5; both ends of the support plate 5 are installed with a receiving seat 6; the top surface of the receiving seat 6 is provided with a pair of symmetrically arranged connecting seats 7; one end of the top surface of the connecting seat 7 is fixedly connected to a fixed column 8; the top surface of the connecting seat 7 is slidably connected to a moving column 9 at one end away from the fixed column 8, and the moving column 9 is driven by a hydraulic system; the top of the workbench 1 The surface frame is provided with an XY motion mechanism 10; the movable end of the XY motion mechanism 10 is fixedly connected with a patch head 11; a feeder 12 is installed on the top surface of the workbench 1 away from the side of the conveyor belt 2; the feeder 12 is the core feeding device of the patch machine, responsible for accurately conveying the various semiconductor components packaged in the tape to the pick-up position of the patch head 11 according to the set step distance; during operation, in order to ensure that the clamping of the PCB does not affect the patch operation of various semiconductor electrical devices at its edge position, the embodiment of the present invention can be used. First, the conveyor belt 2 moves the PCB to be patched to the receiving seat 6 between the paired conveyor belts 2, and then the hydraulic system drives the moving column 9 to move toward the fixed column 8, so that the side of the PCB is squeezed by the moving column and the fixed column. , and then clamp the PCB between the moving column 9 and the fixed column 8, then the electric push rod 4 rises, driving the support plate 5 and the receiving seat 6 to rise, and then driving the PCB at the receiving seat 6 to separate from the pair of conveyor belts 2, and then the rotating seat 3 drives the electric push rod 4, the support plate 5 and the receiving seat 6 to rotate, and rotates the PCB to be patched to the bottom of the XY motion mechanism 10. At this time, the empty receiving seat 6 at the other end of the support plate 5 will be rotated between the pair of conveyor belts 2, and complete the clamping of another PCB to be patched. In this process, the XY motion mechanism 10 will drive the patch head 11 to absorb the semiconductor component at the flyer 12 and stick it to the surface of the PCB, thereby completing the patch operation, and then the electric push rod 4 rises again, and then the rotating seat 3 rotates to move the PCB with completed patch to between the paired conveyor belts 2, and the conveyor belts 2 send away the PCB with completed patch, and then move the new PCB to be patched to the receiving seat 6 between the paired conveyor belts 2. During this process, the receiving seat 6 holding the PCB to be patched at the other end of the support plate 5 is just completed at the patch head 11 to complete the patch operation, thereby achieving the synchronization of patching and loading and unloading, thereby improving the processing efficiency. Therefore, the cooperation of the movable column 9 and the fixed column 8 realizes the clamping of the PCB edge without blocking the edge of the PCB, thereby ensuring the utilization efficiency of the PCB. At the same time, the rotating seat 3 drives the support plate 5 to rotate, achieving the synchronization of patching and loading and unloading, thereby improving the processing efficiency.

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, the top surface of the support plate 5 is provided with a through groove 13 on both sides of the rotating seat 3; a pulley 14 is rotatably connected in the through groove 13; a pull rope 15 is fixedly connected to the top surface of the rotating seat 3, and the pull rope 15 cannot be stretched; the end of the pull rope 15 away from the rotating seat 3 is fixedly connected to the receiving seat 6; the pull rope 15 passes through the through groove 13 and passes through the surface of the pulley 14; a spring 17 is installed between the receiving seat 6 and the support plate 5; during operation, when the electric push rod 4 drives the support plate 5 to rise, since one end of the pull rope 15 is fixedly connected to the rotating seat 3, the end of the pull rope 15 away from the rotating seat 3 It will be pulled, and due to the guiding effect of the pulley 14 at the through groove 13 on the pull rope 15, the pull rope 15 will pull the receiving seats 6 at both ends of the support plate 5 toward the rotating seat 3, and compress the compression spring 17, thereby reducing the rotation radius of the support plate 5, thereby preventing the receiving seats 6 at the end of the support plate 5 from colliding with the XY motion mechanism 10 or the patch head 11, and causing damage to the patch head 11 or the XY motion mechanism 10. When the electric push rod 4 drives the support plate 5 to descend, the compressed spring recovers, driving the receiving seats 6 at both ends of the support plate 5 away from each other, thereby realizing the reset of the receiving seats 6 at both ends of the support plate 5.

[0033] like Figure 3 and Figure 6 As shown, the end of the spring 17 away from the receiving seat 6 is fixedly connected to the limiting block 18; the limiting block 18 is fixedly connected to the top surface of the support plate 5; a limiting hole 19 is provided on the surface of the limiting block 18; the pull rope 15 passes through the limiting hole 19; during operation, when the pull rope 15 is pulled, the pull rope 15 will pass through the limiting hole 19 on the surface of the limiting plate 31, and at this time the limiting hole 19 will limit the pull rope 15, preventing the pull rope 15 from detaching from the surface of the pulley 14, which will cause the pull rope 15 to be unable to pull the receiving seat 6 normally.

[0034] like Figure 1 and Figure 4As shown, the top surface of the workbench 1 is provided with a fixed plate 20 and a movable plate 21; the fixed plate 20 is fixedly connected to the side of the top surface of the workbench 1 away from the rotating seat 3; the movable plate 21 is slidably connected to the side of the top surface of the workbench 1 close to the rotating seat 3; the paired conveyor belts 2 are fixedly connected to the side of the fixed plate 20 and the movable plate 21 close to each other; the surface of the fixed plate 20 is threadedly connected with a threaded rod 22; the threaded rod 22 is rotatably connected to the movable plate 21; during work, when the user needs to process PCBs of different widths, the user needs to adjust the spacing between the paired conveyor belts 2. At this time, the user can screw the threaded rod 22 at the fixed plate 20 so that the threaded rod 22 drives the movable plate 21 close to the fixed plate 20 or away from the fixed plate 20, thereby adjusting the spacing between the paired conveyor belts 2, so as to adapt to PCBs of different widths, thereby improving the scope of application of the embodiment of the present invention.

[0035] like Figure 1 and Figure 4 As shown, a telescopic rod 23 is fixedly connected between the paired conveyor belts 2; a double-thread screw 24 is commonly threadedly connected between the two telescopic rods 23; a connecting rod 25 is commonly slidably connected between the paired connecting seats 7 at both ends of the support plate 5; a pressure plate 26 is provided on the top surface of the receiving seat 6; the two ends of the pressure plate 26 are slidably connected to the receiving seat 6; the top surface of the receiving seat 6 is rotatably connected with a rotating column 27 at the corresponding position of the pressure plate 26; the rotating column 27 is threadedly connected to the pressure plate 26; during work, when the user needs to process PCBs of different lengths, the user needs to adjust the spacing between the conveyor belts 2 on both sides of the support plate 5. At this time, the user needs to screw the double-thread screw 24, and the double-thread screw 24 drives the telescopic rods 23 on both sides thereof to move away from or approach each other, thereby driving the paired conveyor belts 2 fixed with the telescopic rod 23 to move closer to or away from each other, thereby adjusting the conveyor belts on both sides of the support plate 5 The user then screws the rotating column 27 again so that the pressure plate 26 is pressed on the top surface of the connecting seat 7, thereby fixing the connecting seat 7, thereby achieving adaptation to PCBs of different lengths, thereby further improving the scope of application of the embodiments of the present invention.

[0036] like Figure 3 and Figure 7As shown, the two receiving seats 6 are internally rotatably connected with an adjusting rod 28, and the adjusting rod 28 passes through the receiving seat 6; a telescopic rod 29 is fixedly connected between the two adjusting rods 28; the adjusting rod 28 and the rotating column 27 are transmitted by a gear set; during operation, when the user needs to screw the rotating column 27 so that the pressure plate 26 no longer locks the connecting seat 7, the user can screw the adjusting rod 28 at one end. Since the adjusting rod 28 between the two receiving seats 6 is connected together by the telescopic rod 29, the user screwing the adjusting rod 28 at any end will drive the adjusting rod 28 at the other end to rotate synchronously, and the synchronously rotating adjusting rod 28 will drive the rotating column 27 to rotate through the gear set, thereby realizing the synchronous rise and fall of the pressure plates 26 at the receiving seats 6 at both ends, thereby reducing the user's operating difficulty and improving the scope of application of the embodiment of the present invention.

[0037] like Figures 3 to 5 As shown, the conveyor belt 2 near the side of the movable plate 21 is fixedly connected with a support arm 30; the support arm 30 passes through the movable plate 21 and is slidably connected to the movable plate 21; the end of the support arm 30 away from the conveyor belt 2 is fixedly connected to the limit plate 31, and the limit plate 31 corresponds to the position of the connecting rod 25; the top surface of the limit plate 31 is provided with a limit groove 32, and the limit groove 32 is adapted to the connecting rod 25; when working, before adjusting the spacing between the conveyor belts 2 on both sides of the support plate 5, the user needs to first screw the adjusting rod 28 to release the lock of the pressing plate 26 on the connecting seat 7, and at this time the electric push rod 4 is in an unextended state, so the connecting rod 25 will be located in the limit groove 32 on the surface of the limit plate 31, and then the user can adjust The distance between the conveyor belts 2 on both sides of the section support plate 5 is adjusted. At this time, the conveyor belt 2 will also drive the support arm 30 to move synchronously, and the support arm 30 will drive the limit plate 31 to move synchronously. Since the connecting rod 25 is stuck in the limit groove 32 on the surface of the limit plate 31, the limit rod can be driven by the support arm 30, the limit plate 31 and the limit groove 32 to follow the conveyor belts 2 on both sides of the support plate 5 to move synchronously, and the connecting seat 7 is slidably connected to the two ends of the connecting rod 25, so the connecting rod 25 will also drive the connecting seat 7 to move synchronously. Therefore, the user can adjust the distance between the conveyor belts 2 on both sides of the support plate 5 while adjusting the distance between the paired connecting seats 7, thereby reducing the user's operation difficulty and improving the usability of the embodiment of the present invention.

[0038] like Figure 3 and Figure 8As shown, the top surface of the workbench 1 is inlaid with a curved tube 33, and the curved tube 33 is set in a U shape; the end of the curved tube 33 close to the patch head 11 is slidably connected to the insertion rod 34; the end of the curved tube 33 away from the patch head 11 is slidably connected to the pressure rod 35; the curved tube 33 is filled with hydraulic oil; a spring 2 36 is fixed between the insertion rod 34 and the curved tube 33; the bottom surface of the receiving seat 6 is provided with a slot 37; the slot 37 is adapted to the top of the insertion rod 34; when working, when the electric push rod 4 drives the support plate 5 to descend, it is close to the patch head 11 The support plate 5 on one side will squeeze the pressure rod 35 at the elbow 33, causing the pressure rod 35 to drop, and then squeeze the hydraulic oil in the elbow 33, causing the insertion rod 34 at the other end of the elbow 33 to rise, and then the insertion rod 34 is inserted into the slot 37 on the bottom surface of the receiving seat 6, thereby limiting the movement of the receiving seat 6 and preventing the receiving seat 6 from sliding, which in turn causes the PCB at the receiving seat 6 to move, thereby affecting the patch accuracy. At the same time, the insertion rod 34 can also provide support for the side of the receiving seat 6 extending outside the support plate 5 to prevent it from tilting.

[0039] like Figure 8 As shown, the top surface of the insertion rod 34 is fixedly connected with an electromagnet block 38; the bottom of the slot 37 is fixedly connected with a metal sheet 39; the metal sheet 39 is made of magnetizable metal; during operation, when the insertion rod 34 is inserted into the slot 37, the electromagnet block 38 will start and absorb the metal sheet 39 at the bottom of the slot 37, thereby further fixing the receiving seat 6 in the vertical direction and further limiting the movement of the receiving seat 6, thereby ensuring the accuracy of the patch.

[0040] like Figure 7 As shown, the surfaces of the movable column 9 and the fixed column 8 are fixedly connected with a sleeve 40; the top surface of the sleeve 40 can be flush with the top surface of the conveyor belt 2; the top edges of the sleeve 40 are chamfered; during operation, when the PCB is clamped by the movable column 9 and the fixed column 8, the bottom surface of the PCB will be placed on the top surface of the sleeve 40. At this time, the top surface of the sleeve 40 can provide support for the bottom surface of the PCB, thereby preventing the PCB from bending when the patch head 11 presses the semiconductor electronic components on the surface of the PCB, which causes the semiconductor electronic components to not fit well on the surface of the PCB.

[0041] During operation, in order to ensure that the clamping of the PCB does not affect the patch operation of various semiconductor electrical devices at its edge position, an embodiment of the present invention can be used. First, the conveyor belt 2 moves the PCB to be patched to the receiving seat 6 between the paired conveyor belts 2. Then, the hydraulic system drives the moving column 9 to move toward the fixed column 8, so that the side of the PCB is squeezed by the moving column and the fixed column, and then the PCB is clamped between the moving column 9 and the fixed column 8. Then, the electric push rod 4 rises, driving the support plate 5 and the receiving seat 6 to rise, and then driving the PCB at the receiving seat 6 to separate from between the paired conveyor belts 2. Then, the rotating seat 3 drives the electric push rod 4, the support plate 5 and the receiving seat 6 to rotate, and rotates the PCB to be patched to the bottom of the XY motion mechanism 10. At this time, the empty receiving seat 6 at the other end of the support plate 5 will be rotated between the paired conveyor belts 2, and completes the clamping of another PCB to be patched. In this process, the XY motion mechanism 10 will drive the patch head 11 to pick up the semiconductor component at the flyer 12 and stick it to the surface of the PCB, thereby completing the patch operation, and then the electric push rod 4 rises again, and then the rotating seat 3 rotates to move the PCB with completed patch to between the paired conveyor belts 2, and the conveyor belt 2 will send the PCB with completed patch away, and then move the new PCB to be patched to the receiving seat 6 between the paired conveyor belts 2. In this process, the receiving seat 6 of the PCB to be patched, which clamps the PCB to be patched at the other end of the support plate 5, completes the patch operation at the patch head 11, thereby realizing the synchronization of patching and loading and unloading, thereby improving the processing efficiency, thereby realizing the clamping of the PCB edge through the cooperation of the movable column 9 and the fixed column 8, and will not block the edge of the PCB, thereby ensuring the utilization efficiency of the PCB, and at the same time, the rotating seat 3 drives the support plate 5 to rotate, realizing the synchronization of patching and loading and unloading, thereby improving the processing efficiency.

[0042] When the electric push rod 4 drives the support plate 5 to rise, since one end of the pull rope 15 is fixedly connected to the rotating seat 3, the end of the pull rope 15 away from the rotating seat 3 will be pulled. Due to the guiding effect of the pulley 14 at the through groove 13 on the pull rope 15, the pull rope 15 will pull the receiving seats 6 at both ends of the support plate 5 toward the rotating seat 3 and compress the compression spring 17, thereby reducing the rotation radius of the support plate 5, thereby preventing the receiving seats 6 at the end of the support plate 5 from colliding with the XY motion mechanism 10 or the patch head 11, thereby causing damage to the patch head 11 or the XY motion mechanism 10. When the electric push rod 4 drives the support plate 5 to descend, the compressed spring recovers, driving the receiving seats 6 at both ends of the support plate 5 away from each other, thereby realizing the reset of the receiving seats 6 at both ends of the support plate 5.

[0043] When the pull rope 15 is pulled, the pull rope 15 will pass through the limiting hole 19 on the surface of the limiting plate 31. At this time, the limiting hole 19 will limit the pull rope 15, preventing the pull rope 15 from escaping from the surface of the pulley 14, which will cause the pull rope 15 to be unable to pull the receiving seat 6 normally.

[0044] When the user needs to process PCBs of different widths, the user needs to adjust the spacing between the paired conveyor belts 2. At this time, the user can screw the threaded rod 22 at the fixed plate 20 so that the threaded rod 22 drives the movable plate 21 closer to or away from the fixed plate 20, thereby adjusting the spacing between the paired conveyor belts 2 to adapt to PCBs of different widths, thereby improving the scope of application of the embodiment of the present invention.

[0045] When the user needs to process PCBs of different lengths, the user needs to adjust the spacing between the conveyor belts 2 on both sides of the support plate 5. At this time, the user needs to screw the double-threaded screw 24, and the double-threaded screw 24 drives the telescopic rod 23 on both sides thereof to move away from or towards each other, thereby driving the paired conveyor belts 2 fixedly connected to the telescopic rod 23 to move towards or away from each other, thereby adjusting the spacing between the conveyor belts 2 on both sides of the support plate 5. At the same time, the user also needs to adjust the spacing between the paired connecting seats 7 so that the movable column 9 and the fixed column 8 can adapt to the conveyor belts 2 on both sides. To this end, the user needs to screw the rotating column 27 to drive the pressing plate 26 away from the connecting seat 7. Then, the clamping of the pressure plate 26 on the connecting seat 7 is released. At this time, the user can slide the connecting seat 7 to control the distance between the paired connecting seats 7. At the same time, since the connecting seats 7 at both ends of the support plate 5 are slidably connected to the connecting rod 25, adjusting the connecting seat 7 at one end can achieve synchronous adjustment of the connecting seat 7 at the other end, so that the connecting seats 7 at both ends can adapt to the conveyor belts 2 on both sides thereof, and then the user screws the rotating column 27 so that the pressure plate 26 is pressed on the top surface of the connecting seat 7, thereby fixing the connecting seat 7, thereby achieving adaptation to PCBs of different lengths, thereby further improving the scope of application of the embodiments of the present invention.

[0046] When the user needs to twist the rotating column 27 so that the pressure plate 26 no longer locks the connecting seat 7, the user can twist the adjusting rod 28 at one end. Since the adjusting rod 28 between the two receiving seats 6 is connected together by the telescopic rod 29, the user's twisting of the adjusting rod 28 at any end will drive the adjusting rod 28 at the other end to rotate synchronously, and the synchronously rotating adjusting rod 28 will drive the rotating column 27 to rotate through the gear set, thereby realizing the synchronous rise and fall of the pressure plates 26 at the receiving seats 6 at both ends, thereby reducing the user's operating difficulty and improving the scope of application of the embodiment of the present invention.

[0047] The user can adjust the distance between the conveyor belts 2 on both sides of the support plate 5 by rotating the adjusting rod 28 so that the pressure plate 26 releases the lock on the connecting seat 7. At this time, the electric push rod 4 is in an unextended state, so the connecting rod 25 will be located in the limit groove 32 on the surface of the limit plate 31. Then the user can adjust the distance between the conveyor belts 2 on both sides of the support plate 5. At this time, the conveyor belt 2 will also drive the support arm 30 to move synchronously, and the support arm 30 will drive the limit plate 31 to move synchronously. Since the connecting rod 25 is stuck in the limit groove 32 on the surface of the limit plate 31, the limit rod can be driven by the support arm 30, the limit plate 31 and the limit groove 32 to follow the conveyor belts 2 on both sides of the support plate 5 to move synchronously, and the connecting seat 7 is slidably connected to the two ends of the connecting rod 25, so the connecting rod 25 will also drive the connecting seat 7 to move synchronously. In this way, the user can adjust the distance between the conveyor belts 2 on both sides of the support plate 5 while adjusting the distance between the paired connecting seats 7, thereby reducing the user's operation difficulty and improving the usability of the embodiment of the present invention.

[0048] When the electric push rod 4 drives the support plate 5 to descend, the support plate 5 close to the side of the patch head 11 will squeeze the pressure rod 35 at the elbow 33, causing the pressure rod 35 to descend, and then squeezing the hydraulic oil in the elbow 33, causing the insertion rod 34 at the other end of the elbow 33 to rise, and then the insertion rod 34 is inserted into the slot 37 on the bottom surface of the receiving seat 6, thereby limiting the movement of the receiving seat 6 and preventing the receiving seat 6 from sliding, which in turn causes the PCB at the receiving seat 6 to move, thereby affecting the patch accuracy. At the same time, the insertion rod 34 can also provide support for the side of the receiving seat 6 extending outside the support plate 5 to prevent it from tilting.

[0049] When the rod 34 is inserted into the slot 37, the electromagnet block 38 will start and absorb the metal sheet 39 at the bottom of the slot 37, thereby further fixing the receiving seat 6 in the vertical direction and further limiting the movement of the receiving seat 6, thereby ensuring the accuracy of the patch.

[0050] When the PCB is clamped by the movable column 9 and the fixed column 8, the bottom surface of the PCB will be placed on the top surface of the sleeve 40. At this time, the top surface of the sleeve 40 can provide support for the bottom surface of the PCB, thereby preventing the PCB from bending when the patch head 11 presses the semiconductor electronic components on the surface of the PCB, which will cause the semiconductor electronic components to not fit well on the surface of the PCB.
