[0032] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] It should be noted that the first direction in this application is Figure 1 The X direction (i.e., the length direction of the laminate 3) is Figure 1 The Y direction (i.e., the width direction of the laminate 3) and the third direction are Figure 1 The Z direction (that is, the thickness direction of the laminated plate 3).

[0034] like Figures 1 to 14As shown, an embodiment of the present invention provides a PCB processing device for processing a laminated board 3, the laminated board 3 includes a fixing pin 32 and at least one PCB 31, at least one PCB 31 is fixed by the fixing pin 32, the PCB processing device includes a cache device 1 and a host 5, the host 5 has a first end and a second end opposite to each other along a first direction, the first end is provided with a processing area, and the second end is provided with a material changing area, the host may also include an industrial computer, the industrial computer is arranged at the first end, the cache device 1 is arranged at the second end, the cache device 1 is used to cache the laminated board 3 and can provide the laminated board 3 to the host 5. In this embodiment, the end provided with the processing area is defined as the front end, that is, the first end is the front end, and correspondingly, the second end is the rear end. The cache device 1 is arranged at the second end of the host 5 along the first direction, which is different from the prior art in which both the processing area and the material changing area are arranged at the front end, and the layout method is changed, so that the operation space is more reasonable and open. When the operator is loading materials and performing related operations, there is a more sufficient and reasonably planned area to complete the action, avoiding the inconvenience caused by the overly concentrated layout of the front end, such as reducing mutual interference and collision during operation, and being able to more smoothly perform the cache management of the stacked board 3 and the delivery of the stacked board 3 to the host 5. At the same time, the industrial computer and the cache device 1 are respectively arranged at both ends of the host 5, so that the various components inside the equipment are relatively dispersed. When performing daily maintenance and troubleshooting on the cache device 1 or other components inside the host 5, there is a clearer space to implement the operation, unlike the concentrated layout at the front end, where the components are close to each other, it is difficult to use maintenance tools, disassemble components, and other maintenance behaviors, thereby improving the convenience and efficiency of overall maintenance. Among them, the industrial computer can centrally process and control various operations in the entire PCB31 processing process, including the cache, feeding, and processing of the stacked board 3. The industrial computer provides a highly integrated control interface, which is convenient for the operator to monitor the operating status of the equipment in real time, adjust parameters and diagnose faults, and improve the intelligence level of the equipment.

[0035] In one embodiment, the cache device 1 includes a material taking assembly (not shown in the figure), which can limit the fixing pin 32 to drive the stacking plate 3 to rise and fall, or the material taking assembly can drag the stacking plate 3; Or, the cache device 1 includes a material moving component 13, and the material moving component 13 can limit at least one end of the fixed pin 32 to push the stacking plate 3. In this embodiment, the stacking plate 3 is lifted or dragged by the fixed pin 32 of the material taking component, and at least one end of the fixed pin 32 of the material moving component 13 pushes the stacking plate 3, so that the stacking plate 3 can be automatically transported, reducing manual operations and improving processing efficiency. At the same time, the lifting or dragging is achieved by the material taking component, or the stacking plate 3 is pushed by the material moving component 13, which enables the cache device 1 to adapt to stacking plates 3 of different shapes, sizes and weights. For example, for larger-sized stacking plates 3, it can be moved by pushing; and for small or lighter stacking plates 3, it can be moved by dragging or lifting. This multi-mode operation capability increases the adaptability of the cache device 1 to different production tasks and improves the versatility and economy of the equipment. Furthermore, since the forces applied by the material taking component and the material moving component 13 both act on the fixing pin 32, the damage to the PCB can be effectively reduced and the product yield can be improved.

[0036] In one embodiment, the material picking component includes an adsorption structure (not shown in the figure) and / or a clamping structure (not shown in the figure). In this embodiment, the material picking component limits the fixed pin 32 by the clamping structure or the adsorption structure, thereby being able to drive the stacking plate 3 to rise and fall, or being able to drag the stacking plate 3. For some situations where the surface is relatively flat and the fixed pin 32 is tightly combined with the stacking plate 3, the adsorption structure can use the principle of vacuum adsorption to quickly and stably limit the fixed pin 32 to achieve the picking and handling operation of the stacking plate 3. When the stacking plate 3 is heavy, the fixed pin is thick, or a more stable grasping method is required, the clamping structure can firmly fix the fixed pin 32 by mechanical clamping, thereby achieving reliable picking and handling of the stacking plate 3. Different PCB processing tasks may involve various stacking plates 3, and the material, shape, size of the fixed pin and the weight and size of the stacking plate 3 may be different. The adsorption and clamping structures of the material-retrieving component can better adapt to this diversity. Whether it is a small, light stacked plate 3 or a large, heavy stacked plate 3, a suitable material-retrieving method can be found, which improves the versatility and practicality of the equipment, enables it to meet the needs of different customers and different production scenarios, and broadens the application range of the equipment.

[0037] In one embodiment, the clamping structure includes a first clamping member (not shown in the figure) and a second clamping member (not shown in the figure), the first clamping member and the second clamping member are arranged opposite to each other and can clamp the fixing pin 32, so that the first clamping member and the second clamping member can drive the stacking plate 3 to rise and fall; Alternatively, the first clamp and the second clamp are capable of dragging the stacking plate 3. In the present embodiment, when the first clamp and the second clamp are capable of driving the stacking plate 3 to rise and fall, the first clamp and the second clamp are arranged relative to each other and can be clamped from both sides of the fixing pin 32. This double-sided clamping method can accurately fix the fixing pin 32, ensuring the stable movement of the stacking plate 3. When the first clamp and the second clamp are capable of dragging the stacking plate 3, the relative clamping of the first clamp and the second clamp can provide a stable horizontal pulling force. Compared with unidirectional pulling, double-sided clamping can better control the moving direction of the stacking plate 3 so that it moves along a predetermined path.

[0038] In one embodiment, the number of the fixing pins 32 and the number of the clamping structures are both at least two, at least two fixing pins 32 are arranged at intervals along the first direction, and each clamping structure can clamp the corresponding fixing pin 32. In this embodiment, in this embodiment, each clamping structure is installed on the same guide plate assembly 18, and the guide plate assembly 18 extends along the first direction and has good structural strength and rigidity to ensure the stability and position accuracy of the multiple clamping structures during operation. The opening and closing action of each clamping structure is controlled by an independent clamping drive module, and the clamping drive module can use a micro servo motor with a precision screw drive structure or a guide rail slider, etc.; in this way, independent and precise clamping operations can be achieved for each fixing pin 32, and it is convenient to flexibly adjust the clamping force and speed according to different process requirements.

[0039] In one embodiment, the cache device 1 includes a supporting assembly (not shown in the figure), the supporting assembly has a supporting position and an avoidance position, and the supporting assembly can switch between the supporting position and the avoidance position; when the supporting assembly switches to the supporting position, the supporting assembly can support the stacking plate 3; when the supporting assembly switches to the avoidance position, the material taking assembly can transport the stacking plate 3 to the host. The supporting assembly can be a rotating design or a lifting design. Taking the supporting assembly as a rotating design as an example, the supporting assembly is installed on the rotating shaft, and the rotating shaft is driven by a rotating drive motor. The rotating drive motor can use a high-precision servo motor, which can accurately control the rotation angle and speed of the rotating shaft, thereby driving the supporting assembly to switch between the supporting position and the avoidance position. When the supporting assembly is in the supporting position, it can reliably support the stacking plate 3, provide a stable placement foundation for the stacking plate 3 in the cache device 1, and avoid deformation, displacement, etc. of the stacking plate 3 due to lack of suitable support. At the same time, the supporting assembly can be switched to the avoidance position, which creates favorable conditions for the material taking assembly to transport the stacking plate to the host, and avoids the obstruction of the supporting assembly to the operation of the material taking assembly. This enables the laminated board 3 to be smoothly transferred from the buffer device to the host for processing according to the production process requirements, thereby ensuring the continuity of the entire PCB processing process and reducing problems such as transportation jams and delays caused by component interference.

[0040] In one embodiment, the cache device 1 is provided with at least two cache stations 11, at least two cache stations 11 are arranged along the second direction, and the material taking component can drive the stacked plates 3 cached in at least one cache station 11 to be lifted and lowered. In this embodiment, the material taking component can drive the stacked plates 3 cached in one cache station 11 to be lifted and lowered alone, and can also drive the stacked plates 3 cached in multiple cache stations 11 to be lifted and lowered together. When the material taking component drives the stacked plates 3 in one cache station 11 to be lifted and lowered alone, each cache station 11 can be managed independently during the PCB processing process. Accurate single operation helps to quickly provide the appropriate stacked plates 3 to the host 5 according to different production tasks and process requirements, reducing waiting time. At the same time, when multiple stacked plates 3 need to be processed simultaneously, such as in some batch preprocessing or batch detection links, the material taking component can drive the stacked plates 3 in multiple cache stations 11 to be lifted and lowered together. This greatly improves the efficiency of the operation, can complete the transfer of multiple stacked plates 3 at one time, and saves operation time and energy consumption.

[0041] See also Fig.12 In one embodiment, the cache device 1 further includes a cache support frame (not shown in the figure), a cache lifting frame 15 and a cache lifting drive mechanism 19. The cache lifting frame 15 is connected to the cache support frame, and the material collection component is installed on the cache lifting frame 15. The cache lifting drive mechanism 19 is arranged on the cache support frame and connected to the cache lifting frame 15. The cache lifting drive mechanism 19 can drive the cache lifting frame 15 to lift and lower as a whole, so as to drive the material collection component to lift and lower. It can be understood that the cache lifting drive mechanism 19 can drive all the material collection components to lift and lower at the same time by driving the cache lifting frame 15. The cache lifting drive mechanism 19 can select high-precision ball screw lifters or hydraulic lifting platforms and other equipment, which have sufficient driving force and precise positioning capabilities. The lifting connection seat connected to the bottom of the cache lifting frame 15 is closely connected to the cache lifting frame 15, and under the action of the drive motor or hydraulic pump, the cache lifting frame 15 can be driven to lift and lower smoothly in the vertical direction. Through the coordinated work of the cache lifting frame 15 and the cache lifting drive mechanism 19, the cache device 1 can efficiently, accurately and stably realize the caching and processing operations of the stacked plates 3 on multiple workstations, greatly improving the overall operating efficiency and product quality assurance capabilities of the production system.

[0042] In one embodiment, the cache device 1 also includes a cache support frame and a lifting mechanism (not shown in the figure), the lifting mechanism is connected to the cache support frame, the material collection component is connected to the lifting mechanism, and the lifting mechanism can drive the material collection component to rise and fall. In this embodiment, the lifting mechanism can accurately control the lifting height of the material collection component, ensure the precise positioning of the stacked plate 3 during the handling process, reduce errors, and improve the automation level, operating efficiency and safety of the PCB processing equipment. Among them, the lifting mechanism can be powered by a drive motor, and the drive motor can use a high-performance servo motor, and the drive motor is connected to the material collection component through a screw transmission assembly. In other embodiments, each cache station 11 has an independent lifting mechanism for precise control, so that the cache device 1 can flexibly operate the stacked plates 3 of different cache stations 11 independently, greatly improving the adaptability and work efficiency of the cache device 1, and meeting the diverse needs of the cache processing of the stacked plates 3 in complex production processes.

[0043] See also Fig.11 and Fig.14 In one embodiment, the main machine 5 includes a top material roller assembly 21, and the top material roller assembly 21 has a lifting position and a lowering position. The top material roller assembly 21 can switch between the lifting position and the lowering position. When the top material roller assembly 21 switches to the lifting position, the top material roller assembly 21 can support the stacking plate 3. When the top material roller assembly 21 switches to the lowering position, the stacking plate 3 can be placed at a predetermined position of the main machine 5. In this embodiment, the stacking plate 3 can be placed at the predetermined position of the main machine 5, which means that it is placed on the workbench 2 of the main machine 5. The top material roller assembly 21 includes a plurality of evenly distributed rollers, and the rollers are made of rubber or polyurethane material, and have good wear resistance and appropriate elasticity, so as to provide stable supporting force and reduce damage to the surface of the stacking plate 3 when supporting the stacking plate 3. The rollers are mounted on the roller bracket through roller shafts, and the roller bracket is connected to the lifting drive mechanism. The lifting drive mechanism can use electric push rods, cylinders or hydraulic cylinders, etc., which are installed inside the workbench 2, and drive the roller bracket and the roller as a whole to lift and lower in the vertical direction through telescopic action. When the stacked plate 3 needs to be placed on the main machine 5, the lifting drive mechanism first drives the top material roller assembly 21 to rise to the raised position. At this time, the roller is higher than the workbench 2 by a certain height to contact with the bottom of the stacked plate 3 and support the stacked plate 3. Then, the lifting drive mechanism drives the top material roller assembly 21 to descend, so that the stacked plate 3 falls into the workbench 2. The top material roller assembly 21 realizes the convenient placement and precise positioning of the stacked plate 3 by the workbench 2, which improves the efficiency and reliability of the entire work process.

[0044] See also Figure 2 and Figure 3In one embodiment, the host 5 includes a workbench 2, and the cache device 1 includes a cache support frame, a cache frame 14 and a loading drive 12. The cache frame 14 is slidably connected to the cache support frame. The loading drive 12 is arranged on the cache support frame and connected to the cache frame 14. The material picking assembly or the material moving assembly 13 is connected to the cache frame 14. The loading drive 12 can drive the cache frame 14 to move along the first direction, so as to transport the stacked plate 3 to the workbench 2 through the material picking assembly or the material moving assembly 13. It can be understood that the loading drive 12 includes but is not limited to a pneumatic cylinder, a hydraulic cylinder and a linear motor, etc. The loading drive 12 can drive the cache frame 14 to move above the workbench 2 to realize the transportation of the stacked plate 3 to the workbench 2. Through the coordinated work of the cache support frame, the cache frame 14 and the loading drive 12, the cache device 1 can efficiently, stably and accurately transport the stacked plate 3 to the workbench 2, providing a reliable material supply guarantee for subsequent processing or treatment procedures.

[0045] In one embodiment, the host 5 includes a base (not shown in the figure), a workbench 2 and a mobile driving mechanism (not shown in the figure), the workbench 2 is movably connected to the base (not shown in the figure), the mobile driving mechanism is arranged on the base and connected to the workbench 2, and the mobile driving mechanism can drive the workbench 2 to move along the first direction to the cache device 1, so that the workbench 2 can receive the stacked plates 3. The mobile driving mechanism includes but is not limited to a pneumatic cylinder, a hydraulic cylinder and a linear motor, etc. When the workbench 2 needs to receive the stacked plates 3 in the cache device 1, the workbench 2 can accurately move to the cache device 1 to carry out the receiving operation on the stacked plates 3. In this embodiment, the mobile driving mechanism can efficiently and accurately realize the docking between the workbench 2 and the cache device 1 and the transportation of the stacked plates 3, effectively improving the automation degree and production efficiency of the entire equipment.

[0046] In one embodiment, the main machine 5 also includes a gantry (not shown in the figure), which is mounted on the base; the base has a material change area and a processing area, which are respectively located on both sides of the gantry along the first direction, and the workbench 2 can move between the material change area and the processing area. In this embodiment, the workbench 2 can move between the material change area and the processing area, which allows the stacking plate 3 to be easily switched between the preparation state and the processing state. For example, after the preparation work such as loading the stacking plate 3 is completed in the material change area, the workbench 2 can quickly move it to the processing area for processing; after the processing is completed, the workbench 2 can be moved back to the material change area for the next round of material change operations, which reduces the material turnover time, ensures the continuity and efficiency of the processing flow, and makes the entire production rhythm more compact and orderly.

[0047] According to the PCB31 processing equipment provided by the embodiment of the present invention, the industrial computer (i.e., the control core) is set at the first end of the host 5, and the cache device 1 is set at the second end of the host. Such a layout avoids the space crowding problem caused by the processing area and the material change area being concentrated at the front end of the equipment, so that the operator can have a more spacious and convenient operating space when processing, loading, and daily maintenance of the PCB board, thereby improving work efficiency and safety. By separating the control area (industrial computer) from the processing and material change area (cache device), the workflow is clearer and the operation is more orderly, which helps to reduce misoperation and improve processing accuracy, thereby improving product quality. At the same time, since each functional module (such as an industrial computer, a cache device, etc.) is relatively independent in space, when the equipment needs to be upgraded or maintained, it can be operated more conveniently and quickly on a specific module, reducing interference with the entire production line.

[0048] like Fig.15 As shown, in addition, an embodiment of the present invention provides a loading method, which is applied to the PCB31 processing equipment of the above embodiment, and the loading method includes: conveying the stacked plate 3 to the buffer device 1; The stacked plate 3 is transported from the cache device 1 to the host 5. In this embodiment, the loading method corresponds to the reasonable layout of the cache device 1 and the host 5 in the equipment structure (such as the layout characteristics of the cache device 1 at one end of the host 5 mentioned above), avoiding the space crowding problem caused by the processing area and the material replacement area being concentrated at the front end of the equipment, so that the operator can have a more spacious and convenient operating space when processing, loading, and daily maintenance of the PCB board, thereby improving work efficiency and safety. The stacked plate 3 is first transported to the cache device 1, and the cache device 1 can play the role of temporarily storing and arranging the stacked plates. For example, the material taking component or the material moving component 12 and the supporting component in the cache device 1 can ensure that the stacked plate 3 is in the correct position to prevent it from being displaced, tipped over, etc., and when it is subsequently transported to the host 5, it can enter the host 5 with a more accurate posture and position, avoiding problems such as affecting the processing accuracy due to inaccurate loading, and improving the accuracy of loading. The transportation of the stacked plate 3 can be completed by an external conveying device (such as an automatic guided vehicle (AGV trolley), a conveyor belt, etc.). These external devices transport the stacked plates 3 to the position of the buffer device 1, ensuring that the stacked plates 3 are securely placed in the buffer station 11, waiting for subsequent operations. Through the cooperation of the external conveying device (such as the AGV trolley) and the buffer device 1, an automated material conveying process is realized, greatly improving work efficiency.

[0049] In one embodiment, the step of transporting the stacked plate 3 from the cache device 1 to the host 5 specifically includes: Cache device 1 limiting stacking plate 3; driving the cache device 1 to move along a first direction to convey the stacked plate 3; The cache device 1 is driven to place the stacked plates 3 on the host 5. In this step, the cache device 1 will fix the position of the stacked plates 3 to prevent the stacked plates 3 from shifting or sliding during transportation, and ensure that the stacked plates 3 remain stable in the cache device 1. The driving method can be electric drive, pneumatic drive, hydraulic drive, etc.

[0050] In one embodiment, the step of limiting the stacking plate 3 of the cache device 1 specifically includes: The buffer device 1 clamps the fixing pin 32 of the stacked plate 3; Alternatively, the buffer device 1 abuts against the fixing pin 32 along the first direction. The buffer device 1 may grasp the fixing pin 32 by a clamping device (such as a clamp, a pneumatic clamp, etc.), or the buffer device 1 abuts against the fixing pin 32 along the first direction, and applies a force along the first direction to the fixing pin 32 to ensure that the stacking plate 3 does not move in the buffer device 1. Through these two limiting methods, the buffer device 1 can ensure that the stacking plate 3 maintains a precise position during the process of transportation and docking with the workbench 2, thereby improving production efficiency and accuracy.

[0051] In one embodiment, the buffer device 1 is provided with a material taking assembly. When the buffer device 1 clamps the fixing pin 32, the step of driving the buffer device 1 to move along the first direction to convey the stacked plate 3 specifically includes: Drive the material taking assembly to clamp the fixing pin 32; The material taking component is driven to lift the stacking plate 3, and the material taking component is driven to move in the first direction to drive the stacking plate 3 to move; in this way, the material taking component will first lift the stacking plate 3, which can be achieved by a mechanical arm, a pneumatic lifting device or an electric lifting mechanism. After the material taking component lifts the stacking plate 3, it will move in the first direction. This movement is usually driven by a drive system (such as a motor, a cylinder, a servo drive, etc.), and the movement of the material taking component drives the stacking plate 3 to move synchronously. By lifting the stacking plate 3, direct contact between the stacking plate 3 and the cache device 1 can be avoided, friction and wear can be reduced, and the stacking plate 3 can also be transported to the workbench 2 more smoothly.

[0052] Alternatively, the material taking component is driven to move along the first direction to drag the stacking plate 3 to move. The material taking component drags the stacking plate 3 by moving along the first direction. During the movement of the material taking component, the material taking component drives the stacking plate 3 forward by the clamping force. This method has a simple structure and low cost.

[0053] In one embodiment, the buffer device 1 is provided with a material moving assembly 13. When the buffer device 1 abuts against the fixing pin 32 along the first direction, the step of driving the buffer device 1 to move along the first direction to convey the stacked plate 3 specifically includes: Drive the material moving assembly 13 to abut against the fixing pin 32 along the first direction; Drive the material moving assembly 13 to move along the first direction to push the stacking plate 3 to move. When the material moving assembly 13 moves along the first direction, it resists the fixing pin 32 along the first direction and pushes the stacking plate 3 to move along the first direction through the fixing pin 32, so that the stacking plate 3 can be smoothly and accurately transported from the cache device 1 to the target position.

[0054] Specifically, see Figures 4 to 7 The material moving assembly 13 includes a limit driving component 132, a limit sensor 133, a limit elastic component 134, a locking component 135 and a limit seat 136 provided with a blocking portion 1361; the limit driving component 132 is connected to the limit seat 136; it can be understood that the limit driving component 132 includes but is not limited to a linear motor, a pneumatic cylinder and a hydraulic cylinder, etc.; the limit driving component 132 is used to drive the limit seat 136 to move along the second direction.

[0055] The stopper 135 is movably connected to the limit seat 136, and is surrounded by the blocking portion 1361 to form a limit groove 131; one end of the limit elastic member 134 is connected to the limit seat 136, and the other end is connected to the stopper 135; the stopper 135 is moved relative to the limit seat 136 through the limit elastic member 134, so that the stopper 135 blocks or opens the opening of the limit groove 131; it can be understood that the limit elastic member 134 includes but is not limited to a spring, etc., and the limit sensor 133 includes but is not limited to For laser sensors, photoelectric sensors, etc.; the blocking portion 1361 and the locking member 135 are respectively located at the opposite ends of the limiting groove 131 along the first direction. Furthermore, the limiting groove 131 is provided with an opening at one end away from the blocking portion 1361 in the first direction. When the locking member 135 moves up and compresses the limiting elastic member 134, the locking member 135 will open the opening of the limiting groove 131; when the limiting elastic member 134 drives the locking member 135 to move down, the locking member 135 will block the opening of the limiting groove 131.

[0056] The limit sensor 133 is mounted on the limit seat 136 to detect whether the fixing pin 32 is restricted in the limit slot 131. It can be understood that the limit sensor 133 can be mounted on the inner wall of the limit slot 131.

[0057] See also Figures 6 to 8Specifically, the PCB 31 has two fixing pins 32 spaced apart along the first direction. When the PCB 31 moves along the first direction, the limiting seat 136 and the locking member 135 are located above the moving path of the fixing pin 32. After the front fixing pin 32 moves away from directly below the material shifting assembly 13, the limiting driving member 132 drives the limiting seat 136 and the locking member 135 to move downward. When the rear fixing pin 32 moves along the first direction, it will press the locking member 135 upward. The locking member 135 moves upward and compresses the limiting elastic member 13. 4. The locking member 135 will open the opening of the limiting groove 131 away from the end of the blocking portion 1361. After the rear fixing pin 32 moves into the limiting groove 131, the limiting elastic member 134 will drive the locking member 135 to move downward, so that the locking member 135 and the blocking portion 1361 limit the fixing pin 32 in the limiting groove 131; in the process of the feeding drive member 12 driving the cache frame 14 to move along the first direction, the locking member 135 will push the fixing pin 32 along the first direction, so as to drive the PCB 31 to move along the first direction. In this embodiment, the limit sensor 133 can detect in real time whether there is a fixing pin 32 in the limiting groove 131, ensuring that the cache device 1 stably transfers the PCB 31 to the workbench 2. It can be understood that according to the structure of the material moving component 13, those skilled in the art can derive the corresponding structure of the material picking component through some adaptive changes, and the specific structure of the material picking component is not described in detail here.

[0058] See also Figures 4 to 6 In one embodiment, a guide groove 181 and a through groove 182 are provided on the pressure plate of the guide plate assembly 18. The guide groove 181 is arranged at one end of the pressure plate away from the support plate, and passes through the pressure plate along the first direction. The through groove 182 passes through the pressure plate along the second direction and is connected to the guide groove 181. It can be understood that the guide groove 181 is a long strip groove arranged at the bottom of the pressure plate, and the through groove 182 is arranged at the top of the pressure plate. When an external device transports the stacking plate 3 to the cache device 1, the fixing pin 32 can be inserted into the guide groove 181, and the guide groove 181 guides the PCB 31. The material moving assembly 13 can extend into the through groove 182 and the guide groove 181 to limit the fixing pin 32.

[0059] In one embodiment, the host 5 includes a workbench 2, and the step of transporting the stacked plate 3 from the cache device 1 to the host 5 specifically includes: Cache device 1 limiting stacking plate 3; Driving the workbench 2 to move along a first direction; Drive the cache device 1 to place the stacked plates 3 on the workbench 2. In the present embodiment, the stacked plates 3 are precisely positioned in the cache device 1 to prevent displacement or deviation of the stacked plates 3 during transportation. The workbench 2 moves along a first direction so as to be able to move to the interior of the cache device 1 to prepare for receiving the stacked plates 3. The workbench 2 may be driven by a motor, a pneumatic drive or a servo system to move precisely in a specified direction. The cache device 1 limits the stacked plates 3 to ensure that the stacked plates 3 can be smoothly and accurately transported from the cache device 1 to the workbench 2.

[0060] In one embodiment, the cache device 1 is provided with a material taking assembly, and the steps of driving the cache device 1 to place the stacked plate 3 on the workbench 2 specifically include: Drive the material taking assembly to clamp the fixing pin 32; Driving the material taking assembly to move along the third direction to lift the stacking plate 3; Driving the workbench 2 to move along a first direction; The material taking component is driven to place the stacked plate 3 on the workbench 2. Through the automated operation of the material taking component, such as clamping the fixing pin 32, lifting the stacked plate 3, moving the workbench 2, and placing the stacked plate 3, the need for manual intervention is greatly reduced, thereby improving the conveying efficiency and automation.

[0061] In one embodiment, the cache device 1 is provided with a material taking assembly, and the steps of driving the cache device 1 to place the stacked plate 3 on the workbench 2 specifically include: Drive the material taking assembly to clamp the fixing pin 32; Driving the workbench 2 to move along a first direction; Drive the cache device 1 to place the stacking plate 3 on the workbench 2. By driving the material picking assembly to clamp the fixing pin 32, the stacking plate 3 is stably fixed during the transportation process, avoiding the need for manual fixing or adjustment, thereby improving the transportation efficiency. The clamping action of the material picking assembly ensures that the stacking plate 3 will not deviate from the predetermined track due to shaking or sliding during the transportation process, thereby improving the stability of transportation. In this embodiment, before driving the workbench 2 to move along the first direction, the top material roller assembly 21 on the workbench 2 needs to be moved to the raised position. In the process of the workbench 2 moving close to the stacking plate 3, the top material roller assembly 21 can support the bottom of the stacking plate 3 to improve stability, and the use of rolling friction can effectively reduce friction, ensure a smooth process, and reduce damage. When the stacking plate 3 completely reaches the material changing area, the lifting roller assembly 21 moves to the lowering position to place the stacking plate 3 on the workbench 2. During this process, the material picking assembly can also apply pressure to the stacking plate 3 to cooperate with the lifting roller assembly 21 to clamp the two ends of the stacking plate 3 to ensure the stability of the stacking plate 3 when moving.

[0062] In one embodiment, the buffer device 1 is provided with a material moving assembly 13, and the steps of driving the buffer device 1 to place the stacked plate 3 on the workbench 2 specifically include: Drive the material moving assembly 13 to abut against the fixing pin 32 along the first direction; Driving the workbench 2 to move along a first direction; Drive the cache device 1 to place the stacking plate 3 on the workbench 2. By directly driving the material moving assembly 13 to push against the fixing pin 32 along the first direction, the fixing and lifting steps of the stacking plate 3 are simplified, making the conveying process more concise and efficient. Similarly, in the present embodiment, before driving the workbench 2 to move along the first direction, the top material roller assembly 21 on the workbench 2 needs to be moved to the raised position. In the process of the workbench 2 moving close to the stacking plate 3, the top material roller assembly 21 can support the bottom of the stacking plate 3 to improve stability, and the use of rolling friction can effectively reduce friction, ensure smooth process and reduce damage. When the stacking plate 3 completely reaches the material changing area, the top material roller assembly 21 moves to the landing position to place the stacking plate 3 on the workbench 2. During this process, the material taking assembly can also apply pressure to the stacking plate 3 to cooperate with the top material roller assembly 21 to clamp the two ends of the stacking plate 3 to ensure the stability of the stacking plate 3 when moving.

[0063] See also Fig. 9 In one embodiment, the cache device 1 includes a positioning tool 4, the host 5 includes a workbench 2, the workbench 2 is provided with an avoidance hole, and the host 5 has a material replacement area; before the step of conveying the stacked plate 3 to the cache device 1, it also includes: Insert one end of the alignment tool 4 into the avoidance hole; The material taking component or material moving component 13 is located in the material changing area, and at the same time, the workbench 2 is located in the material changing area; Adjust the position of the material picking assembly or material moving assembly 13 so that the material picking assembly or material moving assembly 13 can limit the other end of the alignment jig 4. It can be understood that the avoidance hole corresponds to the position of the fixed pin 32, and the alignment jig 4 is equivalent to simulating the state of the fixed pin 32 inserted into the avoidance hole, and the accurate position of the fixed pin 32 is ensured by pre-calibration, thereby ensuring the limiting effect of the material picking assembly or material moving assembly 13 on the fixed pin 32, and ensuring the stability of transportation. In this embodiment, the alignment jig 4 cooperates with the workbench 2 and the material picking assembly or material moving assembly 13 to form a stable position reference system. Once the alignment jig 4 completes the positioning, the subsequent transportation, placement and other operations of the stacked plate 3 can be performed based on this stable reference, so that the position of the stacked plate 3 in the entire loading process and subsequent processing processes has a high degree of consistency.

[0064] In one embodiment, the host 5 includes a workbench 2, the workbench 2 is provided with an avoidance hole, and the host 5 has a material change area; before the step of conveying the stacked plate 3 to the cache device, it also includes: The material taking component or material moving component 13 is located in the material changing area, and at the same time, the workbench 2 is located in the material changing area; Get the position coordinates of the avoidance hole; The position of the material picking assembly or material moving assembly 13 is adjusted according to the position coordinates so that the material picking assembly or material moving assembly 13 is aligned with the avoidance hole. In this embodiment, the operation of obtaining the position coordinates of the avoidance hole and adjusting the position of the material picking assembly or material moving assembly 13 accordingly provides a clear and definite operation guide for the entire loading process. After the material picking assembly or material moving assembly 13 is accurately aligned with the avoidance hole, each subsequent conveying and placement of the stacked plate 3 can be based on this stable reference, so that the position of the stacked plate in the entire processing process has a high degree of consistency and accuracy.

[0065] See also Figure 2 and Figure 3 In one embodiment, the cache device 1 also includes a supporting frame, a first adjustment component 16, a second adjustment component 17 and a guide plate assembly 18; the first adjustment component 16 is installed on the supporting frame and connected to the guide plate assembly 18, and the material picking component or material moving component 13 is installed on the guide plate assembly 18 through the second adjustment component 17; it can be understood that the first adjustment component 16 and the second adjustment component 17 both include but are not limited to a screw nut assembly, a guide rail slider assembly, etc.; the first adjustment component 16 is used to adjust the position of the material picking component or material moving component 13 on the guide plate assembly 18 along the first direction, and the second adjustment component 17 is used to adjust the position of the material picking component or material moving component 13 on the guide plate assembly 18 along the second direction, so as to realize the position adjustment of the material picking component or material moving component 13.

[0066] According to the feeding method provided by the present invention, corresponding to the reasonable layout of the cache device and the host 5 in the equipment structure (such as the layout characteristics of the cache device 1 at one end of the host 5 mentioned above), the operator has a relatively independent and appropriate operating space at different stages. For example, when conveying the stacked plate 3 to the cache device 1, the operations such as carrying and placing can be conveniently performed in the corresponding area of ​​the cache device 1; when conveying to the host 5 afterwards, the docking and other actions can also be successfully completed at the corresponding position of the host 5, reducing the inconvenience caused by the cramped space and the interference of operations, and optimizing the operating experience. At the same time, the separate feeding steps and corresponding area settings ensure that when a part of the equipment is maintained, it will not be excessively disturbed by the feeding operation of another part at the same time. For example, when performing deep maintenance and repair on the host 5, the transportation from the cache device 1 to the host 5 can be suspended, and the maintenance work can be carried out in an environment without interference from the feeding operation, so as to ensure the quality and safety of the maintenance work, and at the same time, it also helps to shorten the maintenance time and reduce the impact of equipment downtime on production.
