Description

Technical Field

[0001] The present invention relates to the field of PCB substrate feeding equipment, and in particular to a pneumatic hydraulic feeding mechanism and a use method thereof. Background Art

[0002] PCB substrates need to be stacked and packaged after production is completed. During stacking and packaging, since preset solder joints and holes are generally left on the PCB substrates, the PCB substrates need to be placed in a packaging rack with a separation protection groove when packaging. Before packaging, a stacking loader is generally used for stacking and loading. However, in actual use, different types of PCB substrates have different specifications, resulting in different intervals during packaging. The general stacking loader and conveying track structure are relatively fixed. When discharging, the entire equipment often needs to be adjusted, and the operation is relatively cumbersome.

[0012] Preferably, a rotating rod passes through the middle of the side plate, and a threaded section is provided on the outer circumference of the rotating rod.

The rotating rods are threadedly connected to the side plates on the edge of a guide frame through the threaded sections respectively, and the rotating rods are slidably connected to the side plates that are not threadedly connected to them.

A slide is slidably connected to the top of the top frame, and racks are installed on both sides of the slide. Both sides of the slide are meshed with the rotating rods through the racks, and the end of the hydraulic rod is fixedly connected to the slide.

[0013] Preferably, a method for using a pneumatic hydraulic feeding mechanism comprises the following steps: S1. In actual use, people will start the conveyor belt through the console, and the conveyor belt will convey the PCB substrate to the lower part of the fixed frame. The inertia brought by the conveyor belt will transfer the PCB substrate to the top of the adsorption plate. The baffle will block the PCB substrate to prevent the PCB substrate from crossing the boundary. The cylinder inside the bottom bin will drive the adsorption plate and the PCB substrate to rise, so that the PCB substrate will be lifted to the bottom of the feeding belt. The servo motor will drive the driving wheel on one side of the feeding belt to rotate, so that the feeding belt will be driven to rotate synchronously. When the feeding belt rotates, the slot opened on the surface of the feeding belt will clamp the lower PCB substrate and drive it to rise, so as to realize the lifting and transportation of the PCB substrate. S2. During the lifting process, air is extracted through the pump inside the adsorption plate to create a negative pressure environment inside the adsorption plate to achieve stable adsorption of the PCB substrate and avoid dislocation of the PCB substrate during the lifting process. The servo motor works intermittently and rotates a fixed angle to achieve intermittent work, thereby clamping and lifting the PCB substrate in turn. S3. When the feeding belt lifts the PCB substrate, the reduction motor starts to work synchronously, and the reduction motor drives the driving shaft to rotate. The reciprocating thread grooves on both sides of the outer circumference of the driving shaft drive the fixed plates at both ends to reciprocate. The reciprocating movement interval is synchronized with the rotation of the feeding belt. The limit frame at the end of the fixed plate limits the PCB substrate stuck in the slot, so that the ends of the PCB substrate will be more neat during the lifting process. S4. In the process of the fixed plate at the edge moving back and forth to arrange the end of the PCB substrate, when the fixed plates are close to each other, the guide wheel at the bottom of the fixed rod installed on the lower side of the end of the fixed plate will press the swing rod, thereby forcing the swing rods on both sides to approach the limiting wheels. At this time, the limiting wheels will contact the edge of the PCB substrate on the top of the adsorption plate. The approach of the limiting wheels on both sides will realize the centering of the PCB substrate on the top of the adsorption plate, so that the PCB substrate on the top of the adsorption plate will be directly below the feeding belts on both sides, avoiding the deflection of the PCB substrate; S5. When the fixed plate moves away from each other under the drive of the reciprocating thread groove, the limit wheel and the swing arm will be reset under the action of the rebound force of the elastic rod to avoid the collision between the PCB substrate and the limit wheel when the subsequent new PCB substrate is transferred to the adsorption plate; S6. When the PCB substrate is lifted to a predetermined height or the lifting amount reaches a threshold, the electric slide starts to work, driving the push plate to move, and the push plate pushes the PCB substrate out of the card slot, so that the PCB substrate is pushed to the inner side of the guide slot on the guide frame, and the guide wheels on both sides of the guide slot drive the PCB substrate inside the guide slot to be led out, thereby realizing the guided transportation of a large number of PCB substrates; S7. When guiding and conveying the PCB substrate before packaging, the air pump inside the guide frame will extract air and discharge it through the air outlet slot. The discharged gas will float the PCB substrate being conveyed inside the guide slot, thereby slightly lifting the PCB substrate, which will greatly reduce the friction of the PCB substrate inside the guide slot, which is beneficial to the guiding and conveying work of the guide wheel 2. At the same time, part of the gas will have an inclined output direction under the guidance of the air guide slot, thereby assisting the guide wheel 2, speeding up the output speed of the PCB substrate, and facilitating the rapid loading and packaging work; S8. When faced with PCB substrates with different packaging interval requirements, people will control the speed and rotation amount of the servo motor and the reduction motor through the control console, so as to control the spacing of the PCB substrates stuck on the feeding belt. At the same time, people will drive the slide to slide through the hydraulic rod, and the racks on both sides of the slide will drive the gears on both sides meshing with it to rotate synchronously, and the gears will drive the rotating rod to follow the rotation, and the threaded section on the rotating rod will drive each guide frame to move through the side plate, so as to achieve synchronous adjustment of the spacing between the guide frames, so that the guide frame will be aligned with the PCB substrate on the feeding belt.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When the feeding belt of the present invention rotates, the lower PCB substrate will be clamped by the clamping groove opened on the surface of the feeding belt, and driven to rise, so as to realize the lifting and transportation of the PCB substrate. In this process, air will be extracted through the pump body inside the adsorption plate, and a negative pressure environment will be created inside the adsorption plate, so as to realize the stable adsorption of the PCB substrate and avoid the dislocation of the PCB substrate during the rising process. At the same time, the servo motor works intermittently, and for this purpose, it rotates a fixed angle, so as to realize intermittent work, clamp and lift the PCB substrate in turn, and realize orderly feeding work.

[0015] When the feeding belt lifts the PCB substrate, the reduction motor starts to work synchronously, and the reduction motor drives the driving shaft to rotate. The reciprocating thread grooves on both sides of the outer circumference of the driving shaft drive the fixed plates on both sides to move back and forth. The reciprocating movement interval is synchronized with the rotation of the feeding belt. The limit frame at the end of the fixed plate will limit the PCB substrate stuck in the slot, so that the ends of the PCB substrate will be more neat during the lifting process, avoiding the situation where the ends of the upper and lower PCB substrates are in different positions, which may lead to collisions. At the same time, it is beneficial to the subsequent transfer and material transmission work.

[0016] In the process of the fixed plate at the edge moving back and forth to arrange the end of the PCB substrate, when the fixed plates are close to each other, the guide wheel at the bottom of the fixed rod installed on the lower side of the end of the fixed plate will press the swing arm, thereby forcing the swing arms on both sides to approach the limiting wheels. At this time, the limiting wheels will contact the edge of the PCB substrate on the top of the adsorption plate. The approach of the limiting wheels on both sides will achieve the centering of the PCB substrate on the top of the adsorption plate, so that the PCB substrate on the top of the adsorption plate will be directly under the feeding belts on both sides, avoiding the deflection of the PCB substrate, which will result in the inability to fit into the slot during subsequent lifting, which is beneficial to ensure the accuracy of the PCB substrate lifting and transmission process.

[0017] When the fixed plate moves away from each other driven by the reciprocating thread groove, the limit wheel and the rocker arm will be reset under the action of the rebound force of the elastic rod, so as to avoid the collision between the PCB substrate and the limit wheel when the new PCB substrate is subsequently transmitted to the adsorption plate, which affects the continuous loading work, and is beneficial to improving the continuity of the loading work. When the PCB substrate is lifted to a predetermined height or the lifting amount reaches a threshold, the electric slide will start to work, driving the push plate to move, and the push plate will push the PCB substrate out of the slot, so that the PCB substrate will be pushed to the inner side of the guide slot on the guide frame, and the guide wheels on both sides of the guide slot will drive the PCB substrate inside the guide slot to be exported, so as to realize the guided transportation of multiple PCB substrates, which is beneficial to the subsequent group packaging work.

[0018] When guiding and conveying the PCB substrate before packaging, air will be extracted through the air pump inside the guide frame and discharged through the air outlet groove. The discharged gas will float the PCB substrate being conveyed inside the guide groove, thereby slightly lifting the PCB substrate, which will greatly reduce the friction of the PCB substrate inside the guide groove, which is beneficial to the guiding and conveying work of the guide wheel two. At the same time, part of the gas will have an inclined output direction under the guidance of the air guide groove, thereby assisting the guide wheel two, speeding up the output speed of the PCB substrate, and facilitating rapid loading and packaging.

[0019] In actual use, when faced with PCB substrates with different packaging interval requirements, people will control the speed and rotation amount of the servo motor and the reduction motor through the control console, so as to control the spacing of the PCB substrates stuck on the feeding belt. At the same time, people will drive the slide to slide through the hydraulic rod, and the racks on both sides of the slide will drive the gears on both sides meshing with it to rotate synchronously, and the gears will drive the rotating rod to follow the rotation, and the threaded section on the rotating rod will drive each guide frame to move through the side plate, so as to achieve synchronous adjustment of the spacing between the guide frames, so that the guide frame will be aligned with the PCB substrate on the feeding belt, which is beneficial to the transmission of the PCB substrate.

DETAILED DESCRIPTION

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] like Figure 1-Figure 8A pneumatic hydraulic feeding mechanism shown includes a PCB substrate feeding machine 1, which includes a frame 101. A fixing frame 104 is installed on both sides of the rear top of the frame 101. A plurality of feeding belts 109 are arranged inside the fixing frame 104. A servo motor 110 and a reduction motor 111 are fixedly connected to one side of the rear end of the fixing frame 104. A driving wheel is installed at the driving end of the servo motor 110. The driving wheel is arranged on one side of the inner side of the feeding belt 109. A fixing plate 118 is installed at the middle part of the inner side of the feeding belt 109. A driving shaft is fixedly connected to the driving end of the reduction motor 111. Reciprocating thread grooves are provided on the front and rear sides of the outer periphery of the driving shaft. The driving shaft is threadedly connected to the fixing plate 118 through the reciprocating thread groove threads. Evenly distributed card slots 117 are provided on the outer periphery of the feeding belt 109. An electric slide 108 is installed on the top between the fixing frames 104. A push plate 115 is installed at the bottom of the moving end of the electric slide 108. Furthermore, in a specific implementation, people will start the conveyor belt 103 through the control console 102, and the conveyor belt 103 will convey the PCB substrate to the lower part of the fixing frame 104. The inertia brought by the conveyor belt 103 will conduct the PCB substrate to the top of the adsorption plate 113, and the baffle 112 will block the PCB substrate to prevent the PCB substrate from crossing the boundary. The cylinder 119 inside the bottom bin 114 will drive the adsorption plate 113 and the PCB substrate to rise, thereby lifting the PCB substrate to the bottom of the loading belt 109, and the servo motor 110 will drive the driving wheel on one side of the loading belt 109 to rotate, thereby driving the loading belt 109 to rotate synchronously. When the loading belt 109 rotates, the slot 117 opened on the surface of the loading belt 109 will clamp the lower PCB substrate and drive it to rise, thereby realizing the lifting and transportation of the PCB substrate. When lifting, the reduction motor 111 starts working synchronously, and the reduction motor 111 drives the driving shaft to rotate, and the reciprocating thread grooves on both sides of the outer circumference of the driving shaft drive the fixed plates 118 at the two ends to reciprocate, and the reciprocating movement interval is synchronized with the rotation of the feeding belt 109, and the limit frame 116 at the end of the fixed plate 118 will limit the PCB substrate stuck on the inner side of the slot 117, so that the ends of the PCB substrate will be more neat during the lifting process, avoiding the upper and lower PCB substrate ends The position is different, which may cause easy collision. At the same time, it is beneficial to the subsequent transfer material transfer work. When the PCB substrate is lifted to a predetermined height or the lifting amount reaches a threshold, the electric slide 108 will start working and drive the push plate 115 to move. The PCB substrate will be pushed out of the slot 117 by the push plate 115, so that the PCB substrate will be pushed to the inside of the guide slot 136 on the guide frame 134.

[0024] Among them, a fixing rod 126 is installed at the lower part of the side close to the front and rear side fixing plates 118, and a guide wheel 123 is installed at the outer periphery of the bottom of the fixing rod 126.

The outer periphery of one end of the swing rod 125 is rotatably connected to the limiting wheel 124, and the other end of the swing rod 125 is fixedly connected to the swivel 121. An elastic rod 122 is installed between the front and rear side swing rods 125. The lower part of the end away from the front and rear side fixing plates 118 is fixedly connected to the limiting frame 116, and the bottoms of the front and rear side limiting frames 116 are both outwardly expanded; Furthermore, in a specific implementation, when the fixing plate 118 at the edge moves back and forth to arrange the end of the PCB substrate, when the fixing plates 118 are close to each other, the guide wheel 123 at the bottom of the fixing rod 126 installed at the lower side of the end of the fixing plate 118 will press the swing rod 125, thereby forcing the swing rods 125 on both sides to approach the limiting wheels 124. At this time, the limiting wheels 124 will contact the edge of the PCB substrate on the top of the adsorption plate 113. The approach of the limiting wheels 124 on both sides will realize the centering of the PCB substrate on the top of the adsorption plate 113, so that the adsorption plate 113 can be fixed to the center of the PCB substrate. The PCB substrate at the top will be directly below the feeding belts 109 on both sides, avoiding the PCB substrate from deflecting and causing the PCB substrate to fail to fit into the card slot 117 during subsequent lifting, which is beneficial to ensuring the accuracy of the PCB substrate lifting and transmission process. When the fixed plate 118 is driven away from each other by the reciprocating thread groove, the limit wheel 124 and the rocker arm 125 will be reset under the action of the rebound force of the elastic rod 122, avoiding the PCB substrate from colliding with the limit wheel 124 when a new PCB substrate is subsequently transferred to the adsorption plate 113, affecting the continuous feeding work, which is beneficial to improving the continuity of the feeding work.

Both sides of the air outlet groove 132 are opened with air guide grooves 133. The air guide grooves 133 are all inclined, and the air outlet grooves 132 are connected to the output end of the air pump. Furthermore, in a specific implementation, the guide wheels 135 on both sides of the guide groove 136 will drive the PCB substrate inside the guide groove 136 to be exported, thereby realizing the guided transportation of a plurality of PCB substrates, which is beneficial to the subsequent group packaging work. When guiding and transporting the PCB substrate before packaging, the air pump inside the guide frame 134 will extract air and discharge it through the air outlet groove 132. The discharged gas will float the PCB substrate being transported inside the guide groove 136, thereby slightly lifting the PCB substrate, which will greatly reduce the friction of the PCB substrate inside the guide groove 136, which is beneficial to the guided transportation work of the guide wheel 135. At the same time, part of the gas will have an inclined output direction under the guidance of the air guide groove 133, thereby assisting the guide wheel 135, speeding up the output speed of the PCB substrate, and facilitating the rapid loading and packaging work.

[0027] Among them, a rotating rod 130 is passed through the middle of the side plate 131, and a threaded section 137 is arranged on the outer periphery of the rotating rod 130. The thread pitch of the threaded section 137 is enlarged in sequence from top to bottom. The rotating rod 130 is threadedly connected to the side plate 131 at the edge of a guide frame 134 through the threaded section 137.

[0028] Among them, a method for using a pneumatic hydraulic feeding mechanism includes the following operating steps: S1. In actual use, people will start the conveyor belt 103 through the control console 102, and the conveyor belt 103 will convey the PCB substrate to the lower part of the fixing frame 104. The inertia brought by the conveyor belt 103 will conduct the PCB substrate to the top of the adsorption plate 113, and the baffle 112 will block the PCB substrate to prevent the PCB substrate from crossing the boundary. The cylinder 119 inside the bottom bin 114 will drive the adsorption plate 113 and the PCB substrate to rise, so that the PCB substrate will be lifted to the bottom of the feeding belt 109. The servo motor 110 will drive the driving wheel on one side of the feeding belt 109 to rotate, thereby driving the feeding belt 109 to rotate synchronously. When the feeding belt 109 rotates, the lower PCB substrate will be clamped by the card slot 117 opened on the surface of the feeding belt 109, and it will be driven to rise, so as to realize the lifting and transportation of the PCB substrate; S2. During the lifting process, air is extracted through the pump body inside the adsorption plate 113 to create a negative pressure environment inside the adsorption plate 113, thereby achieving stable adsorption of the PCB substrate and preventing the PCB substrate from being misaligned during the lifting process. The servo motor 110 works intermittently and rotates a fixed angle to achieve intermittent work, thereby clamping and lifting the PCB substrate in sequence. S3. When the feeding belt 109 lifts the PCB substrate, the reduction motor 111 starts to work synchronously. The reduction motor 111 drives the driving shaft to rotate, and the reciprocating thread grooves on both sides of the outer circumference of the driving shaft drive the fixing plates 118 at both ends to reciprocate. The reciprocating movement interval is synchronized with the rotation of the feeding belt 109. The limiting frame 116 at the end of the fixing plate 118 limits the PCB substrate stuck in the slot 117, so that the ends of the PCB substrate are more neat during the lifting process. S4. In the process of the fixed plate 118 at the edge moving back and forth to arrange the end of the PCB substrate, when the fixed plates 118 are close to each other, the guide wheel 123 at the bottom of the fixed rod 126 installed on the lower side of the end of the fixed plate 118 will press the swing rod 125, thereby forcing the swing rods 125 on both sides to approach the limiting wheels 124. At this time, the limiting wheels 124 will contact the edge of the PCB substrate on the top of the adsorption plate 113. The approach of the limiting wheels 124 on both sides will realize the centering of the PCB substrate on the top of the adsorption plate 113, so that the PCB substrate on the top of the adsorption plate 113 will be directly below the feeding belts 109 on both sides to prevent the PCB substrate from deflecting; S5. When the fixing plate 118 moves away from each other under the drive of the reciprocating thread groove, the limiting wheel 124 and the swing rod 125 will be reset under the action of the rebound force of the elastic rod 122, so as to avoid the collision between the PCB substrate and the limiting wheel 124 when the new PCB substrate is subsequently transferred to the adsorption plate 113; S6. When the PCB substrate is lifted to a predetermined height or the lifting amount reaches a threshold, the electric slide 108 starts to work, driving the push plate 115 to move, and the push plate 115 pushes the PCB substrate out of the card slot 117, so that the PCB substrate is pushed to the inner side of the guide slot 136 on the guide frame 134, and the guide wheels 135 on both sides of the guide slot 136 drive the PCB substrate inside the guide slot 136 to be guided out, thereby realizing the guided transportation of a plurality of PCB substrates; S7. When guiding and conveying the PCB substrate before packaging, the air pump inside the guide frame 134 will extract air and discharge it through the air outlet groove 132. The discharged gas will float the PCB substrate being conveyed inside the guide groove 136, thereby slightly lifting the PCB substrate, greatly reducing the friction of the PCB substrate inside the guide groove 136, which is beneficial to the guiding and conveying work of the guide wheel 135. At the same time, part of the gas will have an inclined output direction under the guidance of the air guide groove 133, thereby assisting the guide wheel 135, speeding up the output speed of the PCB substrate, and facilitating the rapid loading and packaging work; S8. When faced with PCB substrates with different packaging interval requirements, people will control the speed and rotation amount of the servo motor 110 and the reduction motor 111 through the control console 102, so as to control the spacing of the PCB substrates stuck on the loading belt 109. At the same time, people will drive the slide 127 to slide through the hydraulic rod 129, and the racks on both sides of the slide 127 will drive the gears 128 on both sides meshing with it to rotate synchronously, and the gears 128 will drive the rotating rod 130 to follow the rotation, and the threaded section 137 on the rotating rod 130 will drive each guide frame 134 to move through the side plate 131, so as to achieve synchronous adjustment of the spacing between the guide frames 134, so that the guide frames 134 will be aligned with the PCB substrates on the loading belt 109.

[0029] Working principle: In actual use, people will start the conveyor belt 103 through the control console 102, and the conveyor belt 103 will convey the PCB substrate to the lower part of the fixing frame 104. The inertia brought by the conveyor belt 103 will conduct the PCB substrate to the top of the adsorption plate 113, and the baffle 112 will block the PCB substrate to prevent the PCB substrate from crossing the boundary. The cylinder 119 inside the bottom bin 114 will drive the adsorption plate 113 and the PCB substrate to rise, so that the PCB substrate will be lifted to the bottom of the feeding belt 109. The servo motor 110 will drive the driving wheel on one side of the feeding belt 109 to rotate, thereby driving the feeding belt 109 to rotate synchronously. When the feeding belt 109 rotates, the lower PCB substrate will be clamped by the slot 117 opened on the surface of the feeding belt 109, and driven to rise, so as to realize the lifting and transportation of the PCB substrate. In this process, air will be extracted through the pump body inside the adsorption plate 113 to create a negative pressure environment inside the adsorption plate 113, so as to realize the stable adsorption of the PCB substrate and avoid the misalignment of the PCB substrate during the rising process. The servo motor 110 works intermittently, and for this purpose, it rotates a fixed angle to realize intermittent work, so as to clamp and lift the PCB substrate in turn. When the feeding belt 109 lifts the PCB substrate, the reduction motor 111 starts to work synchronously. The reduction motor 111 drives the driving shaft to rotate, and the reciprocating thread grooves on both sides of the outer circumference of the driving shaft drive the fixing plates 118 at the two ends to reciprocate. The reciprocating movement interval is synchronized with the rotation of the feeding belt 109, and the limiting frame 116 at the end of the fixing plate 118 limits the PCB substrate stuck in the inner side of the slot 117, so that the ends of the PCB substrate will be more neat during the lifting process, avoiding the situation that the ends of the upper and lower PCB substrates are in different positions, which may lead to easy collision. At the same time, it is beneficial to the subsequent transfer material transmission work. In the process of the fixing plate 118 at the edge reciprocating to arrange the ends of the PCB substrate, when the fixing plates 118 are close to each other, the guide wheel 123 at the bottom of the fixing rod 126 installed on the lower side of the end of the fixing plate 118 will press the swing rod 125, thereby forcing the swing rods 125 on both sides to When the limiting wheels 124 are close to each other, the limiting wheels 124 will contact the edge of the PCB substrate on the top of the adsorption plate 113. The approach of the limiting wheels 124 on both sides will realize the centering of the PCB substrate on the top of the adsorption plate 113, so that the PCB substrate on the top of the adsorption plate 113 will be directly below the feeding belts 109 on both sides, avoiding the deflection of the PCB substrate, resulting in the inability to be inserted into the card slot 117 during subsequent lifting, which is beneficial to ensuring the accuracy of the PCB substrate lifting and transmission process. When the fixing plate 118 is driven away from each other by the reciprocating thread groove, the limiting wheels 124 and the swing rod 125 will be reset under the action of the rebound force of the elastic rod 122, avoiding the collision between the PCB substrate and the limiting wheels 124 when a new PCB substrate is subsequently transmitted to the adsorption plate 113, affecting the continuous feeding work, which is beneficial to improving the continuity of the feeding work.When the PCB substrate is lifted to a predetermined height or the lifting amount reaches a threshold, the electric slide 108 will start to work, driving the push plate 115 to move, and the push plate 115 will push the PCB substrate out of the card slot 117, so that the PCB substrate will be pushed to the inner side of the guide slot 136 on the guide frame 134, and the guide wheels 135 on both sides of the guide slot 136 will drive the PCB substrate inside the guide slot 136 to be guided out, so as to realize the guided transportation of a plurality of PCB substrates, which is beneficial to the subsequent group packaging work. When the PCB substrate is guided and transported before packaging, the air pump inside the guide frame 134 will extract air and discharge it through the air outlet groove 132, and the discharged gas will float the PCB substrate being transported inside the guide slot 136, so that the PCB substrate will be slightly lifted, which will greatly reduce the friction of the PCB substrate inside the guide slot 136, which is beneficial to the guided transportation work of the guide wheel 135, and at the same time, part of the gas in the guide slot 133 is There will be an inclined output direction at the bottom, which will assist the guide wheel 135 to speed up the output speed of the PCB substrate, which is conducive to the rapid loading and packaging work. In actual use, when facing PCB substrates with different packaging interval requirements, people will control the speed and rotation amount of the servo motor 110 and the reduction motor 111 through the control console 102, so as to realize the control of the spacing of the PCB substrates stuck on the feeding belt 109. At the same time, people will drive the slide 127 to slide through the hydraulic rod 129, and the gears 128 meshing with the slide 127 on both sides will be driven to rotate synchronously, and the gears 128 will drive the rotating rod 130 to follow the rotation, and the threaded section 137 on the rotating rod 130 will drive each guide frame 134 to move through the side plate 131, so as to realize the synchronous adjustment of the spacing between the guide frames 134, so that the guide frame 134 will be aligned with the PCB substrate on the feeding belt 109, which is conducive to the transmission of the PCB substrate.

The inertia brought by the conveyor belt (103) will transfer the PCB substrate to the top of the adsorption plate (113). The baffle plate (112) will block the PCB substrate to prevent the PCB substrate from crossing the boundary. The cylinder (119) inside the bottom bin (114) will drive the adsorption plate (113) and the PCB substrate to rise, thereby raising the PCB substrate to the bottom of the feeding belt (109). The servo motor (110) will drive the driving wheel on one side of the feeding belt (109) to rotate, thereby driving the feeding belt (109) to rotate synchronously. When the feeding belt (109) rotates, the lower PCB substrate will be clamped by the clamping groove (117) provided on the surface of the feeding belt (109), and driven to rise, thereby realizing the lifting and conveying of the PCB substrate. S2. During the lifting process, air is extracted through the pump body inside the adsorption plate (113), and a negative pressure environment is created inside the adsorption plate (113), so as to achieve stable adsorption of the PCB substrate and prevent the PCB substrate from being misaligned during the lifting process. The servo motor (110) works intermittently and rotates a fixed angle to achieve intermittent work, so as to clamp and lift the PCB substrate in sequence. S3. When the feeding belt (109) lifts the PCB substrate, the reduction motor (111) starts to work synchronously, and the reduction motor (111) drives the driving shaft to rotate.

The reciprocating movement interval is synchronized with the rotation of the feeding belt (109). The limiting frame (116) at the end of the fixing plate (118) limits the PCB substrate stuck in the inner side of the slot (117), so that the ends of the PCB substrate are more neat during the lifting process. S4. In the process of the fixed plate (118) at the edge moving back and forth to arrange the end of the PCB substrate, when the fixed plates (118) are close to each other, the guide wheel (123) at the bottom of the fixed rod (126) installed on the lower side of the end of the fixed plate (118) will press the swing rod (125), thereby forcing the swing rods (125) on both sides to approach the limiting wheels (124). At this time, the limiting wheels (124) will contact the edge of the PCB substrate on the top of the adsorption plate (113). The approach of the limiting wheels (124) on both sides will realize the centering of the PCB substrate on the top of the adsorption plate (113), so that the PCB substrate on the top of the adsorption plate (113) will be directly below the feeding belts (109) on both sides, thereby preventing the PCB substrate from deflecting; S5. When the fixed plate (118) moves away from each other under the drive of the reciprocating thread groove, the limiting wheel (124) and the swing rod (125) are reset under the action of the rebound force of the elastic rod (122), so as to prevent the PCB substrate from colliding with the limiting wheel (124) when a new PCB substrate is subsequently transferred to the adsorption plate (113); S6.

When guiding and conveying the PCB substrate before packaging, the air pump inside the guide frame (134) extracts air and discharges it through the air outlet groove (132). The discharged gas floats the PCB substrate being conveyed inside the guide groove (136), thereby slightly lifting the PCB substrate, greatly reducing the friction of the PCB substrate inside the guide groove (136), and facilitating the guiding and conveying work of the guide wheel 2 (135). At the same time, part of the gas will have an inclined output direction under the guidance of the air guide groove (133), thereby assisting the guide wheel 2 (135) and accelerating the output speed of the PCB substrate, which is conducive to rapid loading and packaging work; S8.
