Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit board processing, and more particularly to a clutch mechanism, a feeding and discharging conveying system, a circuit board processing device and a circuit board conveying method. BACKGROUND

[0002] With the rapid development of consumer electronics and automotive electronics industries, the market demand for circuit boards, such as printed circuit boards (PCBs), continues to grow. In the manufacturing process of printed circuit boards, there are usually multiple links such as drilling and forming. Among them, the forming milling process performed on a numerical control forming machine is an important stage for realizing board segmentation and contour processing. At present, when conveying a circuit board to a numerical control forming machine, a motor direct drive mode is mainly used for transmission control. When stopping or starting the conveying, the motor is usually controlled to start and stop to realize it. However, when conveying heavy materials, the materials will continue to move a certain distance due to the inertia of motion, resulting in a shift in the position of the materials, which does not meet the processing requirements. SUMMARY

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present application is: The present application provides a clutch mechanism for engaging or disengaging the transmission between a power source and a first component of a feeding and discharging conveying system, the feeding and discharging conveying system being used for conveying a stacked board assembly, the stacked board assembly comprising a workbench plate and a plug-in column mounted on the workbench plate, the workbench plate being used for carrying a circuit board, and the plug-in column being used for being inserted into a fixing hole on the circuit board; The clutch mechanism comprises a first gear, a second gear, a moving assembly, a stopper and a third gear; The first gear is in transmission connection with the power source, the third gear is connected with the first component, the moving assembly is connected to the second gear, and the second gear is in meshing with the third gear; The moving assembly can drive the second gear to move to mesh with the first gear, so that the first gear is in transmission connection with the third gear, and then the power source can drive the first component; And / or, the moving assembly can drive the second gear to move to mesh with the stopper and separate from the first gear, so that the third gear is connected with the stopper, and then the stopper can limit the first component.

[0005] In some implementations, the moving component includes a drive element, a guide shaft, and a first bearing. One end of the guide shaft is connected to the telescopic rod of the drive element, the inner ring of the first bearing is fixedly connected to the other end of the guide shaft, and the outer ring of the first bearing is fixedly connected to a second gear.

[0006] In some implementations, the clutch mechanism further includes a fixed seat and a first linear bearing, the first linear bearing being fixedly connected to the fixed seat, the fixed seat having a first through hole, the guide shaft passing through the first through hole and also passing through the first linear bearing.

[0007] In some implementations, the clutch mechanism further includes a fixed seat, the stop is fixed to the fixed seat, and the stop includes a stop tooth; The stop tooth can mesh with the second gear.

[0008] This application provides a loading and unloading conveying system, including a conveying device. The conveying device includes a first motion component, a power source, and a clutch mechanism as described in any of the above implementations. The first motion component includes a first part, and a third gear is fixedly connected to the first part of the first motion component. The power source is connected to the first gear via a transmission connection.

[0009] In some implementations, the first motion component further includes a drive wheel and a timing wheel, the drive wheel and the timing wheel being fixedly connected to the first component, and the drive wheel being used to carry and drive the stacked plate assembly to move; The first motion component comprises at least two, and the synchronous pulleys of the at least two first motion components are linked together by a synchronous belt; the conveying device further includes a first support frame, and the at least two first motion components are spaced apart on the first support frame.

[0010] This application provides a circuit board processing equipment, including a transfer device, a host computer, and a loading and unloading conveying system as described in any of the above implementations. One end of the loading and unloading conveying system is connected to the transfer device, and the other end is connected to the host computer. The circuit board can be transported between the transfer device, the loading and unloading conveying system, and the host computer.

[0011] In some implementations, the host includes a bed and a moving platform, the moving platform being disposed on the bed, and the worktable being detachably connected to the moving platform.

[0012] This application provides a circuit board transportation method, applied to the circuit board processing equipment described in any of the above implementations, the circuit board transportation method comprising: The stacked plate assembly is moved to the conveying device by the transfer device so that the stacked plate assembly is docked with the conveying device. The second gear is driven to move by the driving component, so that the second gear meshes with the first gear, and the first motion component is started by the power source to receive the stacked plate assembly. When the stacked plate assembly moves to the designated position, the driving member drives the second gear to move, so that the second gear meshes with the stop member, and the stop member limits the stacked plate assembly; Drive the conveying device to move so as to dock with the mobile platform; The second gear is driven to move by the drive component, so that the second gear meshes with the first gear, and the first motion component is started by the power source to transport the stacked plate assembly to the mobile platform.

[0014] The main advantages of the clutch mechanism, loading and unloading conveying system, circuit board processing equipment, and circuit board transportation method provided in this application are as follows: The stacking assembly of this application, through the design of the worktable and plug-in pins, uses the plug-in pins to insert into the fixing holes of the circuit board to pre-fix the circuit board on the worktable, which ensures the circuit board is firmly fixed during handling and processing, and helps to reduce the possibility of circuit board deformation during transportation. In addition, by introducing a movable second gear to cooperate with the moving component, the power source and the first component are cleverly switched between disconnection and connection. When normal transportation is required, the moving component pushes the second gear to the required position, so that the first gear meshes with the second gear, and the second gear meshes with the third gear, thereby realizing the transmission between the first gear and the third gear, and realizing the power connection between the power source and the first component; when it is necessary to stop, the moving component moves the second gear away, so that the stop member limits (i.e., brakes) the first component, thereby disconnecting the power source from the first component. In this way, even when transporting a heavy stacking assembly, it can be stopped in time, thereby ensuring the accuracy of the material transportation position and meeting the processing requirements.

[0018] In related technologies, when conveying circuit boards to a CNC forming machine, direct motor drive is mainly used for transmission control. Stopping or starting the conveying process is typically achieved through motor start / stop control. However, when transporting heavy materials, stopping via motor control allows the material to continue moving forward due to inertia, causing a positional shift that does not meet processing requirements. Furthermore, larger circuit boards are prone to deformation during rotation.

[0019] Therefore, this application provides a clutch mechanism, a loading and unloading conveying system, a circuit board processing equipment, and a circuit board transportation method to solve the problems in the related technology.

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0021] Combination Figure 1 and Figure 2 As shown in the figure, this application provides a circuit board processing equipment, including: a transfer device, a main machine 200, and a loading / unloading conveying system 100. One end of the loading / unloading conveying system 100 is connected to the transfer device, and the other end is connected to the main machine 200. The circuit board 300 can be transported between the transfer device, the loading / unloading conveying system 100, and the main machine. In some embodiments, the loading / unloading conveying system 100 can be disposed on one side of the main machine 200, or the loading / unloading conveying system 100 can also be disposed on the machine tool base of the main machine 200.

[0022] For example, the host machine 200 is used to receive the circuit board 300 conveyed by the loading and unloading conveyor system 100 and to process the circuit board 300. The host machine 200 is also used to transfer the processed circuit board 300 to the loading and unloading conveyor system 100. The host machine 200 can be a CNC forming machine. The host machine includes a bed and a moving platform 201, with the moving platform 201 disposed on the bed. The circuit board can be a printed circuit board (PCB), a flexible printed circuit (FPC), a rigid-flex board, a high-density interconnect (HDI), an integrated circuit substrate, a metal substrate, a glass substrate, and a ceramic substrate, etc. In addition, according to function and structure, the circuit board can be divided into single-layer circuit boards and multi-layer circuit structures.

[0023] Combination Figures 5 to 8 As shown in this embodiment, the loading and unloading conveying system 100 includes a stacking plate assembly, which includes a worktable 205 and insertion posts 206 mounted on the worktable 205. The worktable 205 is used to support the circuit board 300, and the insertion posts 206 are used to be inserted into fixing holes on the circuit board 300. The worktable 205 is detachably connected to a mobile platform.

[0024] In this embodiment, the loading and unloading conveying system 100 further includes a conveying device 121 and a lifting device; the conveying device 121 includes a loading mechanism 122 and a unloading mechanism 123 spaced apart in a first direction, the first direction being the height direction of the loading and unloading conveying system 100; the loading mechanism 122 is used to convey the stacked assembly carrying the circuit board 300 to the host 200; the unloading mechanism 123 is used to transfer the stacked assembly and the processed circuit board 300 after the host 200 has processed the circuit board 300 on the stacked assembly; the lifting device is used to drive the conveying device 121 to move in the first direction so that the loading mechanism 122 and the unloading mechanism 123 can respectively correspond to the host 200.

[0025] For ease of description, the height direction of the main unit 200 is defined as the ZZ direction, the width direction (also known as the front-to-back direction) as the YY direction, and the length direction as the XX direction. The height, width, and length directions are all perpendicular to each other. The height direction of the loading / unloading conveyor is parallel to the ZZ direction, the width direction is parallel to the YY direction, and the length direction is parallel to the XX direction.

[0026] The stacking assembly of the loading and unloading conveying system 100 in this embodiment of the application is designed with a worktable 205 and a plug-in post 206. By using the plug-in post 206 to insert into the fixing hole of the circuit board 300, the circuit board 300 can be firmly fixed during handling and processing. The worktable 205 also helps to reduce the possibility of deformation of the circuit board 300 during the conveying process. Furthermore, through the coordinated work of the stacking assembly, the conveying device 121 (including the loading mechanism 122 and the unloading mechanism 123) and the lifting device, manual handling and loading and unloading operations can be replaced. This can reduce the time spent on manual handling. When applied to multi-axis, multi-table equipment, it can solve the inefficiency problem of manual operation of each machine, thereby greatly improving production efficiency.

[0027] Combination Figures 9 to 11 As shown, in some embodiments, the stacking assembly further includes an intermediate pad 207, which is disposed on the worktable 205. Insertion posts 206 also pass through the intermediate pad 207, and the circuit board 300 is placed on the intermediate pad 207. The intermediate pad 207 can protect the worktable 205 during processing and also provide a certain cushioning effect. For example, the intermediate pad 207 can be made of cardboard; while the worktable 205 can be made of bakelite board. This bakelite board can provide support for multiple stacked circuit boards 300, reducing bending deformation of the circuit boards 300 during transportation. The number of insertion posts 206 on the worktable 205 can be one or more, and the specific number can be designed as needed; this application does not limit this. The intermediate pad 207, the worktable 205, and the circuit board 300 are detachable.

[0028] See Figure 11 As shown, in some embodiments, the stacking assembly further includes a limiting member 208, which is fixed to the worktable 205. The limiting member 208 can be a positioning pin. The limiting member 208 and the insertion post 206 are located on opposite sides of the worktable 205. The limiting member 208 can cooperate with the limiting groove in the loading and unloading conveying system 100 to achieve guidance, which facilitates the stacking assembly to avoid skewing during the conveying process and ensures that the stacking assembly moves along a set direction. For example, the worktable 205 can be rectangular, circular, or elliptical. The limiting member 208 can be fixed to the lower surface of the worktable 205 and protrudes from the lower surface by a set length; while the insertion post 206 is fixed to the upper surface of the worktable 205 and protrudes from the upper surface by a set length. The upper surface of the worktable 205 is used to support the circuit board 300 and the intermediate pad 207. The number of limiting members 208 on the worktable 205 can be multiple, such as 2, 3, or 4. Taking a rectangular worktable 205 with 2 limiting members 208 as an example, the two limiting members 208 are spaced apart, and the line connecting the two limiting members 208 can be parallel to the length direction of the worktable 205. This line can also be the centerline of the support plate parallel to its own length direction. The conveying direction of the stacked plate assembly by the loading mechanism 122 or unloading mechanism 123 can be parallel to the length direction of the worktable 205. It is understood that the line connecting the two limiting members 208 can also be parallel to the width direction of the worktable 205.

[0029] For ease of description, in this embodiment of the application, the whole formed by the circuit board 300 and the stacked board assembly is referred to as the board assembly 202. The unprocessed board assembly 202 refers to the circuit board 300 on the stacked board assembly that has not been processed; while the processed board assembly 202 refers to the circuit board 300 on the stacked board assembly that has been processed.

[0030] The conveying device 121 is mainly used to convey the board assembly 202. The loading mechanism 122 can receive the unprocessed board assembly 202 and convey it to the host machine 200. The lifting device can move the loading mechanism 122 to a set height so that the unprocessed board assembly 202 can be conveyed to the host machine 200. After receiving the unprocessed board assembly 202, the host machine 200 processes the circuit board 300 in the board assembly 202, such as cutting or drilling. After the host machine 200 completes the processing of the circuit board 300 in the board assembly 202, the host machine 200 outputs the processed board assembly 202. The lifting device can move the unloading mechanism 123 to a set height so that the processed board assembly can be conveyed to the unloading mechanism 123, and the unloading mechanism 123 then conveys the processed board assembly 202.

[0031] See Figure 12As shown, in some embodiments, the lifting device includes a drive mechanism 203 and a lifting frame 204. The drive mechanism 203 drives the lifting frame 204 to move along a first direction. The conveying device 121 is mounted on the lifting frame 204, thus the lifting frame 204 can improve rigidity and provide stable support for the conveying device 121. Exemplarily, the lifting device also includes a lifting base 209 and a support seat 210, with the support seat 210 fixedly connected to the lifting frame 204. The drive mechanism 203 includes a lead screw 211, a lead screw 211 nut, a linear slide rail 212, a first reducer 213, and a second motor 214. The guide rail of the linear slide rail 212 is fixed to the lifting base 209, and the slider of the linear slide rail 212 is fixedly connected to the support seat 210. The output shaft of the second motor 214 is connected to the input shaft of the first reducer 213, and the output shaft of the first reducer 213 is fixedly connected to one end of the lead screw 211. The lead screw nut and the lead screw are threadedly connected. The thread on the lead screw can be a T-shaped thread. The second motor 214 can be a servo motor. The second motor 214 drives the first reducer 213 to rotate, and the first reducer 213 drives the lead screw 211 to rotate, thereby driving the lead screw nut and the bearing seat 210 to move together in the first direction. The number of lifting base 209, bearing seat 210 and drive mechanism 203 can each be two. One lifting base 209, one bearing seat 210 and one drive mechanism 203 are located at one end of the length direction of the lifting frame 204, and the other lifting base 209, another bearing seat 210 and another drive mechanism 203 are located at the other end of the length direction of the lifting frame 204. This realizes the smooth lifting and lowering of the lifting frame 204, and facilitates the drive mechanism 203 to enable the lifting frame 204 to be located at different heights such as standby height, loading height, and unloading height. The number of conveying devices 121 in the loading and unloading conveying system 100 can be one or more, which can be 2, 3, 4, 5 or 6; multiple conveying devices 121 can be arranged sequentially along the length direction of the lifting frame 204.

[0032] Combination Figure 3 and Figure 4As shown, in some embodiments, the conveying device 121 further includes a guide assembly 215, which is fixed to the lifting frame 204. The loading mechanism 122 and the unloading mechanism 123 each have at least one guide assembly 215. The guide assembly 215 includes a first guide plate 216 and a second guide plate 217, which are spaced apart to form a guide groove. The guide groove includes a guide portion 218 and a limiting portion 219 connected to the guide portion 218. The width of the guide portion 218 gradually decreases from the guide portion to the limiting portion 219. The limiting member 208 can move from the guide portion 218 to the limiting portion 219. Thus, by guiding the sheet metal assembly 202 with the guide assembly 215, the directional movement of the sheet metal assembly 202 can be ensured. For example, each loading mechanism 122 of the conveying device 121 may correspond to a guide component 215, and each unloading mechanism 123 may correspond to a guide component 215; in the height direction of the loading and unloading conveying system 100, the loading mechanism 122 in the conveying device 121 may be located below the unloading mechanism 123. The orientation of the guide portion 218 of the guide component 215 corresponding to the loading mechanism 122 is opposite to the orientation of the guide portion 218 of the guide component 215 corresponding to the unloading mechanism 123.

[0033] In some embodiments, the structure of the feeding mechanism 122 is the same as that of the unloading mechanism 123; the description of the structure of the unloading mechanism 123 can be referred to the description of the structure of the feeding mechanism 122, and will not be repeated in this application.

[0034] Combination Figures 13 to 15 As shown, in some embodiments, the loading mechanism 122 includes a plurality of first motion components 111, a power source, and a clutch mechanism; the clutch mechanism is used to engage or disengage the transmission between the power source and the first component 112. The first component can be a conveyor shaft. The first motion components 111 are used to make the stacking assembly move linearly; it should be noted that in some other possible embodiments, the loading mechanism 122 and the unloading mechanism 123 can also be replaced by a robot, which can be mounted on a gantry frame.

[0035] Combination Figures 13 to 15As shown, in some embodiments, the clutch mechanism includes a first gear 101, a second gear 102, a moving component, a stop 103, and a third gear 104; the first gear 101 is connected to a power source; the second gear 102 is connected to the moving component, and the third gear 104 is connected to the first component 112; the moving component can drive the second gear 102 to move, so that the first gear 101 and the third gear 104 are connected via the second gear 102, thereby enabling the power source to drive the first component 112; or, the moving component can drive the second gear 102 to move, so that the third gear 104 is connected to the stop 103 via the second gear 102, thereby enabling the stop 103 to limit the first component 112.

[0036] This application cleverly achieves the switching of power connection or disconnection between the power source and the first component 112 by introducing a movable second gear 102 in cooperation with the moving component. When normal conveying is required, the moving component pushes the second gear 102 to the required position, so that the first gear 101 meshes with the second gear 102, and the second gear 102 meshes with the third gear 104, thereby realizing the transmission between the first gear 101 and the third gear 104, and thus realizing the power connection between the power source and the first component 112. When stopping is required, the moving component moves the second gear 102 away, so that the stop 103 limits (i.e., brakes) the first component 112, thereby realizing the power disconnection between the power source and the first component 112. In this way, when transporting heavy stacked plate assemblies, it can be stopped in time, thereby ensuring the accuracy of the material transport position and meeting the processing requirements.

[0037] For example, the first component can be a conveyor shaft; the first motion assembly 111 includes a first component 112, and a third gear 104 is fixedly connected to the first component 112 of one of the first motion assemblies 111; a power source is connected to the first gear 101 via transmission. Thus, the engagement or disengagement of the transmission between the first gear 101 and the third gear 104 achieves engagement or disengagement between the first motion assembly 111 and the power source. A moving component enables the second gear 102 to engage or disengage with the first gear 101; a stop 103 is used to lock the second gear 102 when it disengages from the first gear 101; when the second gear 102 engages or disengages from the first gear 101, the third gear 104 remains engaged with the second gear 102. By moving the components to engage or disengage the second gear 102 with the first gear 101, power transmission can be switched on or off. This helps reduce or avoid response delays during motor start-up and shutdown. Furthermore, it avoids energy loss caused by frequent motor starts. Since a motor needs to overcome rotational inertia to start, the instantaneous current is large, consuming extra energy, generating heat, and reducing efficiency. When the motor is running at a stable speed, the current is relatively stable, resulting in higher efficiency and lower energy consumption per unit time. When the second gear 102 disengages from the first gear 101, the stop 103 locks the second gear 102, while the continuous engagement between the third gear 104 and the second gear 102 ensures smooth power transmission. In addition, this clutch mechanism, by switching the engagement relationships between different gears, can distribute power as needed among multiple first components. This not only solves the problems of high cost, complex structure, and difficult control caused by multiple motor drive systems required for multiple conveyor shafts in related technologies, but also further improves the operating efficiency and reliability of the equipment.

[0038] Combination Figures 13 to 15 As shown, in some embodiments, the power source may include a first motor 113, a first bevel gear 114, and a first drive shaft 115; the first bevel gear 114 is fixed on the output shaft of the first motor 113, and the first bevel gear 114 is also fixed on the first drive shaft 115; the first gear 101 is fixed on the first drive shaft 115. The first bevel gear 114 on the output shaft of the first motor 113 meshes with the first bevel gear 114 on the first drive shaft 115, thereby enabling the first motor 113 to drive the first drive shaft 115 to rotate, which in turn drives the first gear 101 to rotate.

[0039] It should be noted that in some other possible embodiments, the power source may also include a speed reducer. The output shaft of the first motor 113 is fixedly connected to the input shaft of the speed reducer. A first bevel gear 114 is fixed on the output shaft of the speed reducer. The first bevel gear 114 fixed on the output shaft of the speed reducer meshes with the first bevel gear 114 on the first transmission shaft 115.

[0040] Combination Figures 13 to 16 As shown, in some embodiments, the first motion component 111 further includes a drive wheel 116 and a synchronous wheel 117, which are fixedly connected to the first component 112 respectively; the synchronous wheels 117 in the multiple first motion components 111 are linked together by a synchronous belt 120. Thus, when the first component 112 of the third gear 104 rotates, it can drive all the other first components 112 in the first motion components 111 to rotate together, thereby realizing that the drive wheels 116 in the multiple first motion components 111 in the feeding mechanism 122 rotate together. For example, the number of drive wheels 116 in the first motion component 111 can be two, and the number of synchronous wheels 117 can be two, which ensures the smooth conveying of the sheet metal assembly by the feeding mechanism 122. During sheet metal conveying, the drive wheels 116 are used to support the sheet metal assembly.

[0041] Combination Figures 13 to 15 As shown, in some embodiments, the feeding mechanism 122 further includes a first support frame 118, on which a plurality of first motion components 111 are spaced apart, and the first support frame 118 can maintain a stable distance between the plurality of first motion components 111. For example, the first component 112 can be mounted on the first support frame 118 via a bearing seat with bearings. To ensure the tension of the synchronous belt 120 and achieve synchronous rotation among the synchronous pulleys 117 of the plurality of first motion components 111, the feeding mechanism 122 may also include a tensioning pulley 119, which is rotatably mounted on the first support frame 118. The first support frame 118 is fixed to the lifting frame 204.

[0042] It should be noted that in some other possible embodiments, the synchronizing wheel 117 in the first motion component 111 can also be replaced with a sprocket, so that the sprockets in the multiple first motion components 111 are linked by a chain.

[0043] In some embodiments, the clutch mechanism has an engaged state and a disengaged state. In the disengaged state, the first gear 101 is separated from the second gear 102, and the second gear 102 is engaged with the stop 103. In the engaged state, the first gear 101 is engaged with the second gear 102, and the second gear 102 is separated from the stop 103. The rotation axes of the first gear 101, the second gear 102, and the third gear 104 are parallel to each other. When the second gear 102 is engaged with the first gear 101, the first gear 101, the second gear 102, and the third gear 104 are all engaged. After the power source transmits power to the first gear 101, the first gear 101 can transmit power to the third gear 104 through the second gear 102. The moving component can cause the second gear 102 to move linearly relative to the first gear 101, and the direction of the linear movement is parallel to the axis of the second gear 102. When the second gear 102 disengages from the first gear 101, the power transmission between them is interrupted. After the stop 103 locks the second gear 102, the stop 103 restricts the rotation of the second gear 102. Since the rotation of the second gear 102 is restricted, the rotation of the third gear 104 meshing with the second gear 102 is also restricted, and finally the second gear 102 and the third gear 104 stop rotating. This allows the clutch mechanism in this embodiment to reduce the workload and wear of the motor compared to the control methods in related technologies that rely on frequent start-stop of the motor, thus extending the service life of the motor and related components.

[0044] Combination Figure 17 and Figure 18As shown, in some embodiments, the clutch mechanism further includes a fixed base 105, and a stop 103 is fixed to the fixed base 105. The stop 103 includes a stop tooth 106; when the second gear 102 and the first gear 101 are separated, the stop tooth 106 meshes with the second gear 102. The fixed base 105 provides stable support for the stop 103 to ensure that the stop 103 remains stationary. Thus, when the stop tooth 106 meshes with the second gear 102, the second gear 102 can be braked. For example, the stop 103 also includes a first connecting portion 107, and the stop tooth 106 is fixedly connected to the first connecting portion 107. The two can be an integral structure, which facilitates the processing and fixing of the stop tooth 106. The first connecting part 107 and the fixed base 105 can be fixedly connected by screws, thereby realizing a detachable fixed connection between the stop 103 and the fixed base 105. The stop 103 can be detachably fixed to the fixed base 105 to facilitate maintenance or replacement of the stop 103. The number of stop teeth 106 on the stop 103 can be one or more, and the multiple stop teeth 106 can be arranged in a straight line, or in a circle or arc. It can be understood that after the second gear 102 is separated from the first gear 101, and the second gear 102 and the third gear 104 remain in a meshed state, the second gear 102 will rotate under the action of inertia until the second gear 102 meshes with the stop teeth 106, thereby realizing the braking of the second gear 102 by the stop teeth 106. During the conveying process of the conveying device 121, the sheet assembly 202 is relatively heavy. Therefore, the drive wheel 116 can drive the movement of the sheet assembly 202 to achieve smooth movement. In addition, under the action of the stop member 103, the braking between the intermediate tooth and the stop member 103 can be achieved, thereby reducing the possibility of the sheet assembly 202 shifting position due to inertia.

[0045] Combination Figure 17 and Figure 18 As shown, in some embodiments, the moving component includes a drive member 108, which enables the second gear 102 to perform linear motion, allowing the second gear 102 to mesh or disengage with the first gear 101. This helps reduce uncertainties during movement, thereby improving the stability of the meshing or disengaging action between the second gear 102 and the first gear 101. Exemplarily, the drive member 108 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder; thus, the telescopic rod of the drive member 108 is the piston rod of the electric cylinder, the piston rod of the pneumatic cylinder, or the piston rod of the hydraulic cylinder. It is understood that the drive member 108 is not limited to the above three structures and can also employ other devices capable of enabling the second gear 102 to perform linear motion.

[0046] CombinationFigure 17 and Figure 18 As shown, in some embodiments, the moving assembly further includes a guide shaft 109 and a first bearing (not shown). One end of the guide shaft 109 is connected to the telescopic rod of the drive member 108, the inner ring of the first bearing is fixedly connected to the other end of the guide shaft 109, and the outer ring of the first bearing is fixedly connected to the second gear 102. This allows the second gear 102 to rotate relative to the guide shaft 109 using the first bearing, ensuring that the rotation of the second gear 102 does not affect the linear movement of the guide shaft 109. It should be noted that in some other possible embodiments, the integrated structure formed by the cooperation of the first bearing and the second gear 102 can also be replaced by a bearing-type gear. For example, one end of the guide shaft 109 can be directly fixedly connected to the telescopic rod of the drive member 108, or a coupling can be used to connect one end of the guide shaft 109 to the telescopic rod of the drive member 108.

[0047] Combination Figure 17 and Figure 18 As shown, in some embodiments, the clutch mechanism further includes a first linear bearing 110, a fixed base 105 having a first through hole (not shown), a guide shaft 109 passing through the first through hole, and the guide shaft 109 also passing through the first linear bearing 110. The first linear bearing 110 is fixedly connected to the fixed base 105. This utilizes the first linear bearing 110 to ensure the stability of the guide shaft 109's linear motion along with the telescopic rod of the drive member 108. For example, the first linear bearing 110 and the fixed base 105 can be fixedly connected by screws; the guide shaft 109 and the first through hole can be spaced apart.

[0048] It should be noted that in some other possible embodiments, the first linear bearing 110 may be directly fixed in the first through hole, and the first linear bearing 110 may be sleeved on the outer surface of the guide shaft 109.

[0049] It is understood that the PCB processing equipment may also include a controller and a position sensor. The controller is electrically connected to the drive unit 108, the position sensor, and the first motor 113. The controller can be a PLC controller or an MCU controller; the position sensor can be a proximity switch or a photoelectric switch. When the drive wheel 116 conveys the board material to the set position, the position sensor detects that the board material has been conveyed to the set position. The controller receives the position signal sent by the position sensor, and then the controller retracts the telescopic rod of the drive unit 108 to drive the second gear 102 to disengage from the first gear 101. When the second gear 102 engages with the stop member 103, the drive wheel 116 is stopped. When the telescopic rod of the drive unit 108 extends, it disengages the second gear 102 from the stop member 103, i.e., it is no longer engaged. Then, the second gear 102 re-engages with the first gear 101, thereby realizing the rotation of the drive wheel 116. It should be noted that, since each loading mechanism 122 and each unloading mechanism 123 has a clutch mechanism, each loading mechanism 122 and each unloading mechanism 123 has a corresponding position sensor. The controller can also be electrically connected to a second motor 214.

[0050] In some embodiments, the circuit board processing equipment further includes a stacking and separating device and a take-up and drop-down device; the stacking and separating device is capable of stacking multiple circuit boards 300 on a stacking assembly; and the take-up and drop-down device is used to receive the stacking assembly carrying multiple unprocessed circuit boards 300 conveyed by the stacking and separating device; the take-up and drop-down device is used to convey the received stacking assembly carrying multiple unprocessed circuit boards 300 to the loading and unloading conveying system 100; and the host machine 200 is used to receive the stacking assembly carrying the circuit boards 300 conveyed by the loading and unloading conveying system 100 and process the circuit boards 300.

[0051] It should be noted that this application embodiment mainly designs the loading and unloading conveying system 100. Therefore, in this embodiment, the unmodified board stacking and separating equipment and board receiving and unloading equipment in the circuit board processing equipment are only briefly described. The worktable is transported to the stacking position of the board stacking and separating equipment. Then, the robot arm of the board stacking and separating equipment places the intermediate pad on the worktable, and finally places the unprocessed circuit board on the intermediate pad, thereby forming a board assembly 202. Subsequently, the board assembly 202 is conveyed to the board receiving and unloading equipment. An empty board assembly refers to one on which no circuit board 300 is placed. The board stacking and separating equipment can also collect the processed board assembly 202 from the material box of the board receiving and unloading equipment. The robot arm of the board stacking and separating equipment first removes the finished circuit board 300 from the board assembly 202, and then removes the intermediate pad and the scrap frame. The board receiving and unloading equipment includes a traveling device and a material bin. The material bin is mounted on the traveling device and can push out the board assembly 202 stored inside, as well as collect the processed board assembly 202. The board receiving and unloading equipment receives unprocessed board assembly 202 output from the stacking and separating equipment and conveys the board assembly 202 to the loading and unloading conveying system 100; the board receiving and unloading equipment can also receive processed board assembly 202 output from the loading and unloading conveying system 100 and convey the board assembly 202 to the stacking and separating equipment. The main unit 200 includes a mobile platform 201, which has a lifting conveying mechanism and a positioning mechanism. The lifting conveying mechanism is used to transport the board assembly 202, and the positioning mechanism is used to position the board assembly 202. The loading and unloading conveyor system 100 is installed on the bed at the rear of the main body of the host machine 200. It primarily receives the board assembly 202 output by the loading and unloading conveyor system 100, facilitating the host machine 200's processing of the board assembly 202 conveyed to the moving platform 201. After the host machine 200 completes the processing of the board assembly 202, a processed board assembly 202 is formed. At this point, the circuit board 300 in the processed board assembly 202 has been milled from a single sheet into multiple smaller sub-circuit boards 300 (which can be called finished boards). Simultaneously, the original single circuit board 300 has become a scrap frame around its perimeter, but the central pad 207 has not been milled through. The loading and unloading conveyor system 100 can also receive the processed board assembly 202 and convey it to the board receiving and unloading equipment.

[0052] This application embodiment also provides a circuit board transportation method, applied to the circuit board processing equipment provided in any of the above embodiments; the circuit board transportation method includes: Step S10: Move the stacked plate assembly to the conveying device 121 via the transfer device so that the stacked plate assembly docks with the conveying device 121; for example, the transfer device can be a plate receiving and discharging device.

[0053] Step S20: Drive the second gear 102 to move via the drive member 108, so that the second gear 102 meshes with the first gear 101, and use the power source to drive the first motion component 111 to start, so as to receive the stacked plate assembly.

[0054] Step S30: When the stacking plate assembly moves to the designated position, the second gear 102 is driven to move by the driving member 108, so that the second gear 102 meshes with the stop member 103, and the stop member 103 limits the stacking plate assembly.

[0055] Step S40: Drive the conveyor 121 to move so as to dock with the mobile platform 201.

[0056] Step S50: Drive the second gear 102 to move via the drive component 108, so that the second gear 102 meshes with the first gear 101, and use the power source to drive the first motion component 111 to start, so as to transport the stacked plate assembly to the mobile platform 201.

[0057] In some embodiments, after conveying the stacked assembly to the moving platform 201 in step S50, the circuit board transportation method further includes: clamping the limiting member 208 by the moving platform 201 to fix the stacked assembly to the moving platform 201. The above-described circuit board transportation method has the same technical effects as the clutch mechanism provided in the foregoing embodiments, and will not be repeated here.

[0058] This application also provides a circuit board processing method, which uses the circuit board processing equipment provided in any of the above embodiments to process the circuit board 300; the above circuit board processing method has the same technical effects as the loading and unloading conveying system 100 provided in the foregoing embodiments, and will not be described again here.

[0059] See Figure 19 As shown, in some embodiments, the circuit board fabrication method includes some or all of the following steps.

[0060] Step S300: The stacked assembly carrying the circuit board 300 is conveyed to the loading mechanism 122.

[0061] In step S400, the lifting device drives the loading mechanism 122 to move along the first direction so that the loading mechanism 122 corresponds to the host machine, and the loading mechanism 122 transports the stacked assembly carrying the circuit board 300 to the host machine 200.

[0062] In step S500, the host 200 processes the circuit board 300 on the stacked assembly.

[0063] In step S600, the lifting device moves the unloading mechanism 123 along the first direction so that the unloading mechanism 123 corresponds to the host machine, and the host machine 200 transports the stacked board assembly and the processed circuit board 300 to the unloading mechanism 123.

[0064] For step S300, the method of conveying the stacked assembly carrying the circuit board 300 to the loading mechanism 122 includes: transporting the board assembly 202 to the rear side of the loading and unloading conveying system 100 by the board take-up and unload device. At this time, the lifting frame 204 of the loading and unloading conveying system 100 is at the standby height. The board take-up and unload device outputs the board assembly 202 to the loading mechanism 122 of the loading and unloading conveying system 100. During this process, the clutch mechanism in the loading mechanism 122 is in the engaged state. The power source outputs power to the drive wheel 116. The drive wheel 116 rotates and drives the board assembly 202 to move in the direction of the moving platform 201 of the host. During the movement, the limiting member 208 of the board assembly 202 is in the guide groove of the guide assembly 215. When the sheet assembly 202 is conveyed to the set position on the feeding mechanism 122, the position sensor detects that the sheet assembly 202 has moved to the set position, and then the clutch mechanism switches from the engaged state to the disengaged state; the power between the power source and the drive wheel 116 is cut off, and at this time the sheet assembly 202 is supported by the drive wheel 116.

[0065] For step S400, the lifting device drives the loading mechanism 122 to move along the first direction so that the loading mechanism 122 corresponds to the host. The method of the loading mechanism 122 conveying the stacked assembly carrying the circuit board 300 to the host 200 includes: the drive mechanism 203 of the loading and unloading conveying system 100 drives the lifting frame 204 to descend to the loading height, the moving platform 201 of the host 200 moves backward and approaches the loading mechanism 122, the clutch mechanism switches from the disengaged state to the engaged state, the drive wheel 116 conveys the board assembly 202 to the lifting conveying mechanism of the moving platform 201, and then the positioning mechanism of the moving platform 201 positions the board assembly 202. After the drive mechanism 203 of the loading and unloading conveying system 100 drives the lifting frame 204 to rise to the standby height, the host 200 can process the board assembly 202. It should be noted that when the host 200 processes the circuit board on the board assembly 202, the stacking assembly and the workpiece table are detachably connected; after the host 200 finishes processing the circuit board on the board assembly 202, the stacking assembly can be separated from the moving platform.

[0066] For step S600, the lifting device moves the unloading mechanism 123 along the first direction so that the unloading mechanism 123 corresponds to the host machine. The method of the host machine 200 conveying the stacked assembly and the processed circuit board 300 to the unloading mechanism 123 includes: the drive mechanism 203 of the loading and unloading conveying system 100 drives the lifting frame 204 to descend to the unloading height, the moving platform 201 of the host machine 200 moves backward and approaches the unloading mechanism 123, the clutch mechanism switches from the disengaged state to the engaged state, at which time the second gear 102 meshes with the first gear 101, and the board assembly... The plate assembly 202 is released by the positioning mechanism of the mobile platform 201 and output to the unloading mechanism 123 by the lifting and conveying mechanism. After the plate assembly 202 is completely conveyed to the set position of the unloading mechanism 123, the position sensor detects that the plate assembly 202 has moved to the set position, and then the clutch mechanism switches from the engaged state to the disengaged state. The power of the drive wheel 116 is cut off, and the drive wheel 116 stops rotating. The plate assembly 202 is supported by the drive wheel 116, and the drive mechanism 203 drives the lifting frame 204 to rise back to the standby height. When the loading mechanism 122 has a new unprocessed plate assembly 202, step S400 is performed. After the unprocessed plate assembly 202 is conveyed to the mobile platform 201, the drive mechanism 203 drives the lifting frame 204 to rise back to the standby height.

[0067] In some embodiments, the circuit board processing method further includes step S700, which involves conveying another stacked assembly carrying the circuit board 300 to the loading mechanism 122. Exemplarily, the method of conveying another stacked assembly carrying the circuit board 300 to the loading mechanism 122 includes: a take-up and unload device transporting the assembly to the rear of the loading and unloading conveying system 100, and conveying another unprocessed board assembly 202 to the loading mechanism 122 of the loading and unloading device. For the docking process between the take-up and unload device and the loading mechanism 122, refer to step S300. Subsequently, the clutch mechanism of the unloading mechanism 123 switches from a disengaged state to an engaged state, and the power source transmits power to the drive wheel 116. The drive wheel 116 drives the board assembly 202 to be output to the hopper of the take-up and unload device. When the board assembly 202 has completely entered the hopper, the clutch mechanism switches from an engaged state to a disengaged state.

[0068] In some embodiments, the circuit board processing method further includes: step S800, where the stacking and separating equipment receives the processed board assembly 202 conveyed by the board receiving and releasing equipment, and performs a sorting operation on the processed board assembly 202.

[0069] In summary, the loading and unloading conveying system 100, circuit board processing equipment, and circuit board processing method provided in this application embodiment have the characteristics of compact structure, low manufacturing cost, and small footprint. They not only improve the production efficiency of processing circuit boards 300 and reduce labor costs, but also reduce the void ratio of the loading and unloading conveying system 100.
