Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0030] The embodiments of this application are described below with reference to the accompanying drawings: refer to Figures 1 to 3 According to a first aspect of the embodiments of this application, a circuit board processing method is proposed, which is applied to a circuit board processing equipment. The circuit board processing equipment includes a worktable 200, a crossbeam 110, and a processing module 120. The crossbeam 110 is movably connected to the worktable 200, and the processing module 120 is connected to the crossbeam 110. The processing method includes the following steps: placing the circuit board on the worktable 200, driving the crossbeam 110 to move along a first direction, so as to drive the processing module 120 to process the circuit board. Therefore, this application moves the crossbeam 110 within the worktable 200, simultaneously moving the processing module 120. When the processing module 120 moves to the circuit board placement position, it can perform operations such as drilling and milling on the circuit board to ensure that the circuit board meets the usage requirements. Compared to the solution where the worktable 200 moves, the feed motion in the first direction (i.e., the Y direction) is achieved by the movement of the crossbeam. Therefore, this application does not need to reserve or only needs to reserve a small amount of space for the movement of the worktable 200. The space occupied by the worktable 200 can be used as effective processing space, achieving efficient use of space and reducing site occupation costs. In some embodiments, the worktable 200 can be fixed to avoid vibration of the circuit board caused by the movement of the worktable 200, which helps to ensure the processing accuracy of the circuit board.
[0031] Specifically, the circuit board processing method in this application establishes a first direction, a second direction, and a third direction that are mutually perpendicular as positioning references. The first and second directions can be horizontal, and the third direction can be vertical. A crossbeam 110 moves relative to the worktable 200 along the first direction. A processing module 120 is connected to the crossbeam 110. The processing module 120 can move synchronously with the crossbeam 110 relative to the worktable 200 and can also move relative to the crossbeam 110 along the second direction. By adjusting the positions of the crossbeam 110 and the processing module 120, the processing module 120 can be positioned relative to any position on the worktable 200. When the processing module 120 moves to the processing position of the circuit board, it is driven to approach the circuit board along the third direction for processing. During the processing, both the crossbeam 110 and the processing module 120 can move.
[0032] The movement of the crossbeam 110 relative to the worktable 200 includes, but is not limited to, movement along the first direction. It can also move along the second direction relative to the worktable 200, or move in any direction within the plane of the worktable 200 used to support the circuit board. This allows for position adjustment of the crossbeam 110 relative to the worktable 200, enabling each processing module 120 to move with the crossbeam 110 to any position within the worktable 200's arrangement range to process the circuit board, making circuit board processing more flexible. Furthermore, the movement of the processing module 120 relative to the crossbeam 110 includes, but is not limited to, movement along the second direction, and can also be along the first direction, making position adjustment of the processing module 120 more flexible. The movement of the crossbeam 110 relative to the worktable 200 can be coarse adjustment, while the position adjustment of the processing module 120 relative to the crossbeam 110 can be fine adjustment. Therefore, this application can achieve both processing efficiency and positioning accuracy through rapid movement of the crossbeam 110 combined with fine adjustment of the processing module 120.
[0033] The aforementioned processing module 120 may have multiple modules. For example, multiple processing modules 120 are connected to one side of the crossbeam 110 along the first direction. Each processing module 120 may be arranged at intervals along the second direction. The first direction and the second direction may be two mutually perpendicular directions in the horizontal plane. The movement of the crossbeam 110 can simultaneously drive the movement of multiple processing modules 120, thereby improving the position adjustment efficiency. Furthermore, each processing module 120 may move synchronously relative to the crossbeam 110 along the second direction, or move independently relative to the crossbeam 110, thereby enabling more flexible position adjustment of each processing module 120.
[0034] The workbench 200 can be equipped with multiple workstations, each carrying a circuit board. During processing, each processing module 120 can correspond to each workstation in a three-way direction to process the circuit boards carried in each workstation simultaneously. Alternatively, multiple processing modules 120 can correspond to the same workstation simultaneously in a three-way direction, allowing multiple processing modules 120 to process the circuit boards in the same workstation at the same time. The circuit board processing method of this application is more flexible.
[0035] It should be noted that the movement of each of the above processing modules 120 along the third direction can be driven by a linear motor, cylinder, electric push rod, or other drive device.
[0036] refer to Figures 2 to 5 In the above-mentioned circuit board processing method, the processing module 120 may further include a first processing unit 121 and a second processing unit 122. The specific steps of the processing module 120 in processing the circuit board include: driving the first processing unit 121 to process the circuit board, and simultaneously driving the second processing unit 122 to process the circuit board.
[0037] The first processing unit 121 and the second processing unit 122 can process the same circuit board simultaneously. By setting up multiple processing units 122, processing efficiency can be improved. Different circuit boards can also be processed in parallel, and both can be processed synchronously, which simplifies the control logic and makes the processing method more streamlined and efficient.
[0038] Taking one processing module 120 corresponding to each workbench 200 as an example, the circuit board processing method is as follows: Step 1: Place the circuit board on each workbench 200; Step 2: Move the drive beam 110 to move the processing module 120; Step 3: Drive all first processing units 121 to process the circuit board, and at the same time drive all second processing units 122 to process the circuit board. All first processing units 121 are connected, and all second processing units 122 are connected.
[0039] This application is configured with multiple worktables 200 and multiple corresponding processing modules 120. Each processing module 120 includes a first processing unit 121 and a second processing unit 122. The first processing units 121 of each processing module 120 can be connected to achieve synchronous driving, and the second processing units 122 of each processing module 120 can be connected to achieve synchronous driving. This cascaded processing method ensures processing consistency, reduces the number of driving components, and lowers costs.
[0040] The aforementioned processing module 120 may also include a third processing unit, a fourth processing unit, a fifth processing unit, and other processing units. The corresponding processing units in each processing module 120 may also be connected to drive synchronously.
[0041] This embodiment does not restrict the movement sequence of each processing unit along the first direction and the second direction. That is, each processing unit can move along the first direction with the crossbeam 110 first and then move relative to the crossbeam 110 along the second direction, or it can move relative to the crossbeam 110 along the second direction first and then move along the crossbeam 110 along the first direction, or it can move simultaneously along the first and second directions, as long as it can be adjusted to the corresponding position.
[0042] After alignment is completed, the processing operation is started, driving each processing unit to move in the third direction towards the workstation. The processing unit may be equipped with a drilling tool, and can drive the drilling tool to rotate around the drilling tool as the rotation center. As the processing unit moves towards the workstation in the third direction, it performs drilling operations on the circuit board carried on the workstation until it reaches the preset feed start position and stops feeding.
[0043] In some embodiments, the workstation may also move along a first direction and / or a second direction to facilitate the correction of minor errors such as circuit board assembly errors, workstation deformation, and system errors, making the processing more flexible. For example, the workstation may move within a range of 0 to 10 mm along the first direction, and / or within a range of 0 to 10 mm along the second direction.
[0044] refer to Figures 1 to 7 The aforementioned circuit board processing method may further include multiple worktables 200 arranged side by side, each worktable 200 corresponding to a processing module 120. Specifically, the method includes: placing the circuit board on each worktable 200, driving the crossbeam 110 to move, thereby moving the processing module 120, driving all first processing units 121 to process the circuit board, and simultaneously driving all second processing units 122 to process the circuit board. All first processing units 121 are connected, and all second processing units 122 are connected. This method is beneficial for improving the batch processing efficiency of circuit boards and helps ensure the consistency of processing quality across multiple circuit boards.
[0045] Specifically, the first processing unit 121 and the second processing unit 122 can be drilling units, each including a drilling motor and a drill bit. The output shaft of the drilling motor is fixedly connected to the drill bit via a coupling. Starting the drilling motor drives the drill bit to rotate, thus performing the drilling action. All first processing units 121 are connected by rigid connecting brackets or connecting rods, forming a single unit. All second processing units 122 are connected by another rigid connecting bracket or connecting rod of the same structure, with the connection method consistent with that of the first processing units 121, ensuring that all second processing units 122 are also connected. The crossbeam 110 is slidably connected to the guide rail on the frame via a slider. The extension direction of the guide rail is the movement direction of the crossbeam 110. The drive mechanism for driving the crossbeam 110 consists of a servo motor and ball screw assembly, a linear motor, etc. The two ends of the ball screw are mounted on the worktable 200 via bearing seats. The axis of the screw is parallel to the extension direction of the guide rail. The nut of the ball screw is fixedly connected to the crossbeam 110. The output shaft of the servo motor is fixedly connected to one end of the ball screw via a coupling. Starting the servo motor can drive the screw to rotate, which in turn drives the crossbeam 110 to move linearly along the guide rail via the nut.
[0046] This application uses a workbench 200, with each workbench 200 corresponding to a processing module 120. All processing modules 120 are integrated on a synchronously movable crossbeam 110, so that after the crossbeam 110 drives all processing modules 120 to the processing position, the circuit boards of multiple workbench 200 can be processed simultaneously. Compared with the traditional method of processing one by one on a single workbench 200, there is no need to wait for the previous circuit board to be processed before the next one is processed, which reduces the processing waiting time of a single circuit board and helps to improve processing efficiency. Furthermore, since all first processing units 121 are connected by rigid connecting brackets and all second processing units 122 are connected by rigid connecting brackets, all first processing units 121 can achieve synchronous rotation and feed actions under the same control signal, and all second processing units 122 can also achieve synchronous rotation and feed actions. This avoids the action delay or parameter deviation that may occur due to independent control of a single processing unit, and ensures that the circuit boards of each worktable 200 are processed under the same processing parameters. This helps to ensure the consistency of the drilling diameter, drilling depth and milling contour of multiple circuit boards, thereby enhancing the quality stability of mass-produced circuit boards.
[0047] refer to Figures 1 to 7 In some embodiments, the circuit board processing equipment may further include at least two drive components 130, with at least one drive component 130 having a distance greater than zero from both ends of the crossbeam 110 along the second direction. The step of driving the crossbeam 110 to move specifically includes at least two drive components 130 simultaneously driving the crossbeam 110 to move along the first direction, which is beneficial to improving the deformation of the crossbeam 110, improving the stability of the crossbeam 110 movement process, and also helps to improve the alignment accuracy between the processing module 120 and the worktable 200.
[0048] Specifically, along the vertical direction of the movement of the crossbeam 110 relative to the worktable 200 (which can be understood as the length direction of the crossbeam 110), two drive components 130 are symmetrically distributed in the middle of the crossbeam 110 along the length direction of the crossbeam 110. In this embodiment, two drive components 130 are specifically provided. Each drive component 130 adopts a permanent magnet synchronous linear motor structure. Each linear motor includes a stator and a mover. The stator is a long strip-shaped guide rail structure, and the mover is a slider structure that matches the stator. The mover can slide linearly along the extension direction of the stator, and the linear motor directly drives the mover to move through the electromagnetic force between the stator and the mover.
[0049] The stator of the linear motor in each drive assembly 130 is bolted to the frame. The extension direction of the stator is parallel to the extension direction of the original guide rail below the crossbeam 110, ensuring that the moving direction of the mover is consistent with the expected moving direction of the crossbeam 110. The moving part of the linear motor in each drive assembly 130 is fixedly connected to a pre-set connecting seat in the middle of the crossbeam 110. The connecting seat is a metal block structure welded to the lower surface of the crossbeam 110. The side of the connecting seat has a mounting groove that matches the moving part. For example, an internal hexagonal bolt can be passed through the side wall of the connecting seat and engage with the threaded hole on the moving part to fasten the moving part to the connecting seat, thereby achieving a fixed connection between the drive assembly 130 and the middle of the crossbeam 110. The linear motors of both drive assemblies 130 are electrically connected to the same controller, which can output synchronous pulse control signals to ensure that the energizing sequence, current magnitude, and direction of the two linear motors are completely consistent, thereby ensuring that the start-up time, moving speed, and moving direction of the two moving parts are synchronized.
[0050] In some embodiments, the crossbeam 110 may not have a connecting seat, that is, the crossbeam 110 is directly connected to the mover of the linear motor. This connection method can reduce the height of the equipment and reduce material costs.
[0051] The specific steps for moving the crossbeam 110 include: when it is necessary to move the processing module 120, the controller simultaneously outputs synchronous pulse control signals to the linear motors of the two drive components 130. The two linear motors are synchronously energized under the same signal trigger. After energization, a synchronous electromagnetic driving force is generated between the stator and the mover of each linear motor. Since the stator is fixed on the frame, the electromagnetic driving force pushes the mover to move linearly along the extension direction of the stator. The movers of the two drive components 130 drive the middle part of the crossbeam 110 through the connecting seat. Since the two movers move at the same speed and in the same direction under the action of the synchronous control signal, and the driving force on the crossbeam 110 is balanced, the crossbeam 110 moves smoothly along the extension direction of the original guide rail under the joint drive of the two drive components 130 until all processing modules 120 move to the processing position aligned vertically with the circuit board of the corresponding worktable 200. At this time, the controller stops outputting control signals, the two linear motors are synchronously de-energized, the movers stop moving, and the crossbeam 110 stops accordingly. The two linear motors are driven synchronously through the same controller, which still ensures that the middle of the crossbeam 110 receives a balanced driving force, avoids the crossbeam 110 from shifting, and ensures the advantages of smooth movement of the crossbeam 110 and the alignment accuracy of the processing module 120.
[0052] It should be noted that, in the vertical direction along the moving direction of the crossbeam 110 relative to the worktable 200, the crossbeam 110 includes two opposite ends, and the area in the middle between the two ends is the middle part of the crossbeam 110.
[0053] refer to Figures 1 to 3According to a second aspect of this application, a circuit board processing apparatus is provided, employing the processing method described in any of the above embodiments to perform processing operations. The circuit board processing apparatus includes a frame, a worktable 200, a crossbeam 110, and a processing module 120. The worktable 200 is disposed on the frame and is used to support the circuit board. The crossbeam 110 is movably connected to the frame, and the processing module 120 is connected to the crossbeam 110. The circuit board processing apparatus further includes a drive assembly 130, which is mounted on the frame and connected to the crossbeam 110. The drive assembly 130 is capable of driving the crossbeam 110 to move relative to the worktable 200. This facilitates stable support of the circuit board and adjustment of the processing position.
[0054] Specifically, the frame serves as the base and can be made of materials such as marble. The worktable 200 can be a rectangular metal plate structure. The crossbeam 110 is movably connected to the frame and mounted on the worktable 200. The worktable 200 is equipped with a positioning structure for positioning circuit boards. For example, the positioning structure includes positioning pins and / or adjustable clamping blocks. The positioning pins can be cylindrical metal parts and can be installed on the worktable 200 by plugging them in. The circuit board has pre-set positioning holes that engage with the positioning pins to position the circuit board on the worktable 200. The adjustable clamping blocks can be installed on the surface of the worktable 200 and spaced apart from the positioning pins. The clamping blocks include a fixed seat and a movable pressure rod. The fixed seat is fixed to the surface of the worktable 200 by bolts, and the movable pressure rod is connected to the fixed seat by threads. Rotating the movable pressure rod causes its lower end to press against the upper surface of the circuit board, thereby stably fixing the circuit board to the surface of the worktable 200. In some embodiments, the worktable 200 is fixed as a whole on the horizontal platform of the equipment frame to stably support the circuit board to be processed.
[0055] The aforementioned crossbeam 110 can be a rectangular metal gantry structure. The crossbeam 110 and the frame are movably connected by a slider guide rail structure. Specifically, a slider is fixed to the lower surface of each end of the crossbeam 110. The slider is a metal part with a groove on the inner side, and a wear-resistant bushing is provided in the groove. Guide rails are fixed on both sides of the frame. The guide rails are long strip-shaped metal rails that match the grooves of the sliders. The grooves of the sliders slide with the guide rails, so that the crossbeam 110 can move linearly relative to the worktable 200 along the extension direction of the guide rails. This movable connection structure can reduce the frictional resistance when the crossbeam 110 moves and ensure that the crossbeam 110 moves smoothly.
[0056] refer to Figures 1 to 7The aforementioned circuit board processing equipment may further include at least two drive components 130. The drive components 130 are located between the crossbeam 110 and the frame, connected to the frame, and positioned at the middle of the crossbeam 110. At least one drive component 130 has a distance greater than zero from the end of the crossbeam 110. Each drive component 130 is used to drive the crossbeam 110 to move relative to the frame. The drive components 130 provide both driving and support for the crossbeam 110. Positioning the drive components 130 at the middle of the crossbeam 110 helps to improve the deformation of the crossbeam 110, enhances the stability of the crossbeam 110's movement relative to the frame, and ensures the alignment accuracy between the processing module 120 and the frame.
[0057] Specifically, this embodiment includes two drive components 130. Similar to the drive components 130 described above, each drive component 130 can be a linear motor, cylinder, electric actuator, lead screw drive structure, or other similar drive structure. Both drive components 130 are located within the space between the crossbeam 110 and the frame. In some embodiments, the two drive components 130 are symmetrically distributed along the length of the crossbeam 110 at its center. The center of the crossbeam 110 can be defined as any region between the two ends of the crossbeam 110 along its length, provided that the distance from the end of each drive component 130 to the end of the crossbeam 110 is greater than zero. In some embodiments, one drive component 130 may also be located at the end of the crossbeam 110, and the other drive component 130 may also be located at the center of the crossbeam 110.
[0058] If the drive assembly 130 is a linear motor, the specific principle by which each drive assembly 130 drives the crossbeam 110 to move relative to the worktable 200 is as follows: When it is necessary to adjust the position of the processing module 120, the synchronous controller outputs control signals to the two drive assemblies 130 simultaneously. After the stators of the two drive assemblies 130 are energized, they generate an alternating magnetic field. The magnetic field generates an electromagnetic driving force on the mover along the extension direction of the stator. Since the control signals of the two drive assemblies 130 are synchronized, the two movers move synchronously in a straight line along the stator under the action of the electromagnetic driving force. The movers drive the middle part of the crossbeam 110 through the connecting seat. Under the synchronous traction of the two movers, the crossbeam 110 moves smoothly relative to the worktable 200 along the slider guide structure at both ends until the processing module 120 reaches the preset processing position. The controller stops outputting signals, the drive assembly 130 stops working, and the crossbeam 110 remains in the target position. Therefore, the arrangement of the drive component 130 in this application can shorten the support span of the crossbeam 110, improve the deformation of the crossbeam 110, and thus improve the stability of the crossbeam 110's movement. Moreover, compared to setting more support positions, this embodiment facilitates the assembly of the crossbeam 110.
[0059] refer to Figures 1 to 7The aforementioned crossbeam 110 includes a first end and a second end opposite to each other. The crossbeam 110 is provided with a first connecting part 111 and a second connecting part 112. The drive assembly 130 includes a first drive assembly 131 and a second drive assembly 132. The first drive assembly 131 is connected to the first connecting part 111, and the second drive assembly 132 is connected to the second connecting part 112. The minimum distance from the first connecting part 111 to the first end and the second end is greater than zero, and the minimum distance from the second connecting part 112 to the first end and the second end is also greater than zero. This is beneficial to further improve the force balance of the crossbeam 110 and at the same time helps to enhance the stability of the crossbeam 110 during movement.
[0060] Specifically, the lower surface of the crossbeam 110 is provided with a first connecting part 111 and a second connecting part 112. The first connecting part 111 and the second connecting part 112 can be rectangular metal boss structures. The metal bosses are fixedly connected to the lower surface of the crossbeam 110. The first connecting part 111 and the second connecting part 112 are distributed at intervals along the length direction of the crossbeam 110 and are both located in the non-end area of the crossbeam 110. Both drive components 130 are located in the space between the crossbeam 110 and the worktable 200. The first drive component 131 is fixedly connected to the first connecting part 111, and the second drive component 132 is fixedly connected to the second connecting part 112. In this embodiment, by setting the first connecting part 111 and the second connecting part 112 in the non-end area of the crossbeam 110 and connecting the first drive component 131 and the second drive component 132 respectively, the overall force on the crossbeam 110 is more evenly distributed when it moves. This effectively avoids the problem of excessive local stress in the crossbeam 110 caused by the driving force being concentrated at the end or in a single area, further improving the bending deformation problem of the crossbeam 110 and helping to further improve the stability of the crossbeam 110 during movement. The first connecting part 111 and the second connecting part 112 can also be the structure of the crossbeam 110 itself, and the part connecting the crossbeam and the drive component 130 can be used as the connecting part.
[0061] refer to Figures 3 to 7 The minimum distance amm from the first connecting part 111 to the first end and the distance bmm from the second connecting part 112 to the second end satisfy: a=b. This arrangement makes the first connecting part 111 and the second connecting part 112 symmetrically arranged about the midpoint of the crossbeam 110, thereby driving the first drive assembly 131 and the second drive assembly 132 to be symmetrically distributed. This is beneficial to achieving symmetrical balance of force on the crossbeam 110, further enhancing the smoothness of the crossbeam 110's movement, and also helps to improve the uniformity of load distribution.
[0062] refer to Figures 1 to 7 The aforementioned circuit board processing equipment includes at least two crossbeams 110, which are arranged at intervals along the driving direction of the drive assembly 130. Each crossbeam 110 has a processing module 120 on at least one side, which enables multi-station collaborative processing and improves processing efficiency.
[0063] Specifically, both crossbeams 110 are long, high-strength alloy gantry structures or carbon fiber gantry structures extending horizontally. The two crossbeams 110 have the same length and are arranged in parallel with intervals. Each crossbeam 110 has a processing module 120 on at least one side, that is, each crossbeam 110 can have a processing module 120 on the side facing the other crossbeam 110 and / or the side facing away from it. There can be multiple processing modules 120. In addition, both crossbeams 110 are equipped with independent drive components 130 to adjust the interval between the two crossbeams 110 or the horizontal position of the processing module 120, which is beneficial to adapt to the processing needs of circuit boards of different sizes or thicknesses and form multi-station collaborative operation.
[0064] refer to Figures 1 to 7 The aforementioned processing modules 120 are multiple, each including a first processing unit 121 and a second processing unit 122. Each processing module 120 is configured such that the first processing units 121 and the second processing units 122 operate synchronously. This helps ensure consistency in multi-station processing, while also improving overall processing efficiency and reducing the complexity of processing control.
[0065] Specifically, multiple processing modules 120 are evenly distributed along the length of the crossbeam 110. The structural specifications of all processing modules 120 can be consistent. Each processing module 120 is fixedly equipped with a first processing unit 121 and a second processing unit 122. The first processing unit 121 and the second processing unit 122 are arranged side by side along the length of the crossbeam 110 within each processing module 120. Their processing actions do not interfere with each other. The first processing unit 121 of different processing modules 120 are synchronously linked, and the second processing unit 122 of different processing modules 120 are synchronously linked. For example, when processing is performed, the drilling motors of all first processing units 121 are started synchronously. Under the dual action of signal and mechanical constraints, the feed mechanism synchronously drives the drill bit to move down, and drills the circuit boards at corresponding positions synchronously. At the same time, the interval between adjacent processing units can be synchronously adjusted, and the adjustment interval is more consistent, thus avoiding the relative position error caused by adjusting the processing components one by one. Therefore, the circuit board processing equipment in this embodiment can also take into account both adjustment efficiency and adjustment accuracy.
[0066] In some embodiments, the crossbeam 110 and the processing module 120 are movably connected via a guide assembly. Specifically, the guide assembly has a slider and a guide rail that are movably connected. The guide rail is mounted on the crossbeam 110, and the processing module 120 is mounted on the slider. The circuit board processing equipment may also include an adjustment assembly disposed between the slider and the guide rail. The adjustment assembly may include multiple rolling elements, such as ball bearings, arranged sequentially between the slider and the guide rail. When the crossbeam 110 undergoes slight deformation, causing the guide rail to also deform, the adjustment assembly can, to a certain extent, reduce the impact of guide rail deformation on the slider's movement accuracy, thereby ensuring the processing accuracy of the processing module 120.
[0067] refer to Figures 1 to 7 The workbench 200 is fixedly mounted on the machine frame.
[0068] refer to Figures 1 to 7 According to a third aspect of the embodiments of this application, a circuit board production line is proposed, including multiple circuit board processing devices as described in the above embodiments. The circuit board production line also includes a conveyor line extending along a second direction, which may be the extension direction (length direction) of the crossbeam 110. The conveyor line may include a conveying component, such as at least one of a conveyor chain, conveyor belt, or conveyor wheels, for providing circuit boards to the circuit board processing devices. The circuit board processing devices are arranged sequentially along the second direction, and / or, the circuit board processing devices are disposed on both sides of the conveyor line along a first direction, where the second direction may be the driving direction of the drive component 130, and the second direction is perpendicular to the first direction. This enables the production line to achieve continuous processing of multiple processes and / or parallel processing of the same process, which is beneficial to improving overall production efficiency.
[0069] Specifically, circuit boards can be transported between various circuit board processing equipment using conveyor tracks. The conveyor system includes a main conveyor track and branch conveyor tracks. The main conveyor track extends along the workpiece conveying direction, while the branch conveyor tracks are arranged perpendicular to the main conveyor track to connect parallel circuit board processing equipment. The conveyor tracks can employ a chain drive structure, with the chain driven by a motor in cyclical motion. The circuit boards are placed on a carrier, and the carrier is connected to the chain via buckles. The buckles engage with the chain through slots, causing the carrier to move with the chain.
[0070] When arranged sequentially along the workpiece conveying direction, the output end of the preceding circuit board processing equipment is connected to the input end of the following circuit board processing equipment via a main conveyor track. The base edge of the circuit board processing equipment may have a track interface, and the end of the main conveyor track is fixed to the track interface, allowing the carrier to smoothly transfer from one circuit board processing equipment to the next. When arranged parallel to each other perpendicular to the conveying direction, the input and output ends of each circuit board processing equipment are connected to branch conveyor tracks. The branch conveyor tracks are connected to the main conveyor track via a steering mechanism. The steering mechanism can be a rotating platform, capable of driving the carrier to change the conveying direction.
[0071] Therefore, the production line of this application adopts a structure in which multiple circuit board processing equipment are arranged sequentially and / or perpendicularly side by side along the workpiece conveying direction. This allows the production line to achieve both continuous processing of multiple processes and parallel processing of the same process. When arranged sequentially along the conveying direction, the circuit boards can pass through each circuit board processing equipment in the process sequence, avoiding the problem of a long process caused by a single circuit board processing equipment having to complete all processes. When arranged perpendicularly side by side, multiple circuit board processing equipment can process the same process simultaneously, solving the problem of insufficient capacity of a single circuit board processing equipment, thereby improving overall production efficiency.
[0072] Furthermore, when processing requirements change or some circuit board processing equipment malfunctions, the number of equipment involved in processing can be increased or decreased by adjusting the conveyor path without changing the equipment layout, making production operations more flexible and stable.
[0073] In some embodiments, when multiple circuit board processing devices perform the same process, the multiple circuit board processing devices are arranged sequentially along the second direction, and / or arranged on both sides of the conveyor line along the first direction, so that a single conveyor line can sequentially feed materials to each circuit board processing device, thereby improving the degree of automation.
[0074] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
