[0042] In an embodiment, buffer device 1 includes a material taking assembly (not shown in the figure), and the material taking assembly can limit fixed pin 32 to drive laminated board 3 to lift or drag laminated board 3;

[0043] Or, the buffer device 1 includes a material moving assembly 13 capable of limiting at least one end of the fixed pin 32 to push the laminated board 3. In this embodiment, through the material taking assembly limiting the fixed pin 32 to drive the laminated board 3 to lift or drag the laminated board 3, and the material moving assembly 13 limiting at least one end of the fixed pin 32 to push the laminated board 3, the automatic laminated board 3 conveying can be realized, the manual operation is reduced, and the processing efficiency is improved.

And since the forces exerted by the material taking assembly and the material moving assembly 13 are all acting on the fixed pin 32, the damage to the PCB can be effectively reduced, and the product yield can be improved.

[0044] In an embodiment, the material taking assembly includes a suction structure (not shown in the figure) and / or a clamping structure (not shown in the figure). In this embodiment, the material taking assembly limits the fixed pin 32 through the clamping structure or the suction structure, which can drive the laminated board 3 to lift or drag the laminated board 3. For some relatively flat surfaces and fixed pins 32 that are closely combined with the laminated board 3, the suction structure can use the principle of vacuum suction to quickly and stably limit the fixed pin 32, realize the picking and carrying operation of the laminated board 3. When the laminated board 3 is heavy, the fixed pin is thick, or a more stable grabbing method is needed, the clamping structure can firmly fix the fixed pin 32 through mechanical clamping, thereby realizing reliable picking and carrying of the laminated board 3. Different PCB processing tasks may involve various laminated boards 3, and the material quality, shape, size of the fixed pin and the weight, size of the laminated board 3 may differ. The suction and clamping structures of the material taking assembly can better adapt to such diversity, whether it is a small, light laminated board 3 or a large, heavy laminated board 3, an appropriate material taking method can be found, improving the versatility and practicality of the equipment, making it able to meet the needs of different customers and different production scenarios, and widening the application range of the equipment.

[0045] In an embodiment, the clamping structure includes a first clamping piece (not shown in the figure) and a second clamping piece (not shown in the figure), which are oppositely arranged and capable of clamping the fixed pin 32, so that the first clamping piece and the second clamping piece can drive the laminated board 3 to lift;

[0046] Or, the first clamping piece and the second clamping piece can drag the laminated plate 3. In the embodiment, when the first clamping piece and the second clamping piece can drive the laminated plate 3 to rise and fall, the first clamping piece and the second clamping piece are oppositely arranged, and the clamping can be performed from both sides of the fixing pin 32. The double-side clamping mode can accurately fix the fixing pin 32, and ensure the stable movement of the laminated plate 3. When the first clamping piece and the second clamping piece can drag the laminated plate 3, the relative clamping of the first clamping piece and the second clamping piece can provide stable horizontal pulling force. Compared with single-direction pulling, the double-side clamping can better control the movement direction of the laminated plate 3, and make the laminated plate 3 move along the predetermined path.

[0047] In an embodiment, the number of the fixing pins 32 and the number of the clamping structures are both at least two, the at least two fixing pins 32 are arranged along the first direction, and each clamping structure can clamp a corresponding fixing pin 32. In the embodiment, each clamping structure is mounted on the same guide plate assembly 18, the guide plate assembly 18 extends along the first direction and has good structural strength and rigidity, so as to ensure the stability and position accuracy of the plurality of clamping structures during operation. The opening and closing actions of each clamping structure are controlled by independent clamping driving modules, which can adopt micro servo motors matched with precision screw transmission structures or guide rail sliders, etc. In this way, independent and accurate clamping operations of each fixing pin 32 can be realized, and the clamping force and speed can be flexibly adjusted according to different process requirements.

[0048] In an embodiment, the buffer device 1 comprises a supporting assembly (not shown in the figure), which has a supporting position and a avoiding position, and can be switched between the supporting position and the avoiding position. When the supporting assembly is switched to the supporting position, the supporting assembly can support the laminated plate 3; when the supporting assembly is switched to the avoiding position, the taking-out assembly can transport the laminated plate 3 to the main machine. The supporting assembly can be designed to rotate or lift. Taking the rotating design of the supporting assembly as an example, the supporting assembly is mounted on a rotating shaft, and the rotating shaft is driven by a rotating driving motor. The rotating driving motor can be a high-precision servo motor, which can accurately control the rotation angle and speed of the rotating shaft, so as to drive the supporting assembly to switch between the supporting position and the avoiding position. When the supporting assembly is in the supporting position, it can reliably support the laminated plate 3, and provide a stable placement basis for the laminated plate 3 in the buffer device 1, so as to avoid deformation and displacement of the laminated plate 3 due to lack of appropriate support. At the same time, the supporting assembly can be switched to the avoiding position, which creates favorable conditions for the taking-out assembly to transport the laminated plate to the main machine, and avoids the obstruction of the supporting assembly to the operation of the taking-out assembly. The laminated plate 3 can be smoothly transferred from the buffer device to the main machine for processing according to the production process requirements, which ensures the continuity of the entire PCB processing process, and reduces the problems of transportation jamming and delay caused by component interference.

[0049] In an embodiment, the buffer device 1 is provided with at least two buffer stations 11 arranged along the second direction, and the taking assembly is capable of lifting the laminated boards 3 buffered in the at least two buffer stations 11. In this embodiment, the taking assembly can lift the laminated boards 3 buffered in one buffer station 11 alone, or lift the laminated boards 3 buffered in multiple buffer stations 11 together. When the taking assembly lifts the laminated boards 3 buffered in one buffer station 11 alone, it makes it possible to manage each buffer station 11 independently in the PCB processing process. Precise single operation helps to quickly provide the main machine 5 with suitable laminated boards 3 according to different production tasks and process requirements, and reduces the waiting time. At the same time, when multiple laminated boards 3 need to be processed simultaneously, for example, in some batch preprocessing or batch detection links, the taking assembly can lift the laminated boards 3 buffered in multiple buffer stations 11 together. This greatly improves the operation efficiency and enables the transfer of multiple laminated boards 3 at one time, saving operation time and energy consumption.

[0050] Please refer to Figure 12 In an embodiment, the buffer device 1 further comprises a buffer support frame (not shown in the figure), a buffer lifting frame 15, and a buffer lifting driving mechanism 19. The buffer lifting frame 15 is connected to the buffer support frame, the taking assembly is installed on the buffer lifting frame 15, and the buffer lifting driving mechanism 19 is arranged on the buffer support frame and connected to the buffer lifting frame 15.

It can be understood that the buffer lifting driving mechanism 19 can drive all the taking assemblies to lift simultaneously by driving the buffer lifting frame 15. The buffer lifting driving mechanism 19 can be selected from high-precision ball screw lifting machines or hydraulic lifting platforms, etc., which have sufficient driving force and precise positioning capability. The lifting connecting seat connected to the bottom of the buffer lifting frame 15 is closely connected to the buffer lifting frame 15, and under the action of the driving motor or hydraulic pump, it can drive the buffer lifting frame 15 to move stably along the vertical direction. Through the cooperative work of the buffer lifting frame 15 and the buffer lifting driving mechanism 19, the buffer device 1 can efficiently, accurately and stably realize the buffering and processing operation of the laminated boards 3 in multiple stations, greatly improving the overall operation efficiency of the production system and the product quality guarantee capability.

The lifting mechanism can be powered by a driving motor, which can be a high-performance servo motor. The driving motor is connected to the material taking assembly through a screw transmission assembly. In other embodiments, each buffer station 11 has an independent lifting mechanism for accurate control, so that the buffer device 1 can flexibly operate the laminated board 3 of different buffer stations 11 independently, greatly improving the adaptability and working efficiency of the buffer device 1, and meeting the diversified needs of laminated board 3 buffer processing in complex production processes.

[0052] Referring to Figure 11 and Figure 14 In an embodiment, the host machine 5 comprises a material lifting roller assembly 21, which has a raised position and a lowered position, and can switch between the raised position and the lowered position. When the material lifting roller assembly 21 is switched to the raised position, it can support the laminated board 3, and when the material lifting roller assembly 21 is switched to the lowered position, the laminated board 3 can be placed at a predetermined position of the host machine 5.

The material lifting roller assembly 21 comprises a plurality of evenly distributed rollers made of rubber or polyurethane, which have good wear resistance and appropriate elasticity to provide stable support force when supporting the laminated board 3 and reduce damage to the surface of the laminated board 3. The rollers are installed on the roller bracket through the roller shaft, and the roller bracket is connected to the lifting driving mechanism. The lifting driving mechanism can be selected from electric push rods, air cylinders or hydraulic cylinders, etc., which are installed inside the workbench 2 and drive the roller bracket and the rollers to move vertically by extension and retraction. When the laminated board 3 needs to be placed on the host machine 5, the lifting driving mechanism first drives the material lifting roller assembly 21 to rise to the raised position, at which the rollers are higher than the workbench 2 by a certain height to contact and support the bottom of the laminated board 3, and then the lifting driving mechanism drives the material lifting roller assembly 21 to descend, so that the laminated board 3 falls into the workbench 2. The material lifting roller assembly 21 realizes convenient placement and accurate positioning of the laminated board 3 on the workbench 2, improving the efficiency and reliability of the entire work process.

It can be understood that the feeding driving member 12 includes but is not limited to a pneumatic cylinder, a hydraulic cylinder and a linear motor, etc. The feeding driving member 12 can drive the buffer frame 14 to move above the workbench 2, so as to deliver the laminated board 3 to the workbench 2. Through the cooperation of the buffer support frame, the buffer frame 14 and the feeding driving member 12, the buffer device 1 can efficiently, stably and accurately deliver the laminated board 3 to the workbench 2, thereby providing reliable material supply guarantee for subsequent processing or handling procedures.

[0054] In an embodiment, the host 5 comprises a base (not shown in the figure), the workbench 2 and a moving driving mechanism (not shown in the figure), the workbench 2 is movably connected to the base (not shown in the figure), the moving driving mechanism is arranged on the base and connected to the workbench 2, and the moving driving mechanism can drive the workbench 2 to move in the first direction into the buffer device 1, so that the workbench 2 can receive the laminated board 3.

[0056] According to the PCB 31 processing equipment provided in the embodiment of the utility model, the industrial computer (namely the control core) is arranged at the first end of the main machine 5, and the cache device 1 is arranged at the second end of the main machine, so that the space congestion problem caused by the fact that the processing area and the material changing area are concentrated at the front end of the equipment is avoided, the operator can have more spacious and convenient operation space when processing the PCB, feeding and daily maintaining the equipment, and the work efficiency and safety are improved. By separating the control area (industrial computer) from the processing and material changing area (cache device), the work flow is more clear and the operation is more orderly, which helps to reduce the misoperation and improve the processing precision, thereby improving the product quality. Meanwhile, since the functional modules (such as the industrial computer and the cache device) are relatively independent in space, when the equipment needs to be upgraded or maintained, the specific module can be operated more conveniently and quickly, and the interference to the whole production line is reduced.

[0057] As shown in Figure 15 the utility model provides a kind of feeding method, applied to the PCB 31 processing equipment of above-mentioned embodiment, and feeding method includes:

[0058] The laminated board 3 is transported to the cache device 1.

[0059] The laminated board 3 is transported from the cache device 1 to the main machine 5. In the embodiment, the feeding method corresponds to the reasonable layout of the cache device 1 and the main machine 5 on the equipment structure (such as the layout features of the cache device 1 at one end of the main machine 5 mentioned above), which avoids the space congestion problem caused by the fact that the processing area and the material changing area are concentrated at the front end of the equipment, so that the operator can have more spacious and convenient operation space when processing the PCB, feeding and daily maintaining the equipment, thereby improving the work efficiency and safety. The laminated board 3 is first transported to the cache device 1, which can temporarily store and arrange the laminated board. For example, the material taking assembly or material moving assembly 12 and the supporting assembly in the cache device 1 can ensure that the laminated board 3 is in the correct position, prevent it from shifting, falling and other situations, and when transported to the main machine 5 later, it can enter the main machine 5 with more accurate posture and position, avoid the problem of affecting the processing precision due to inaccurate feeding, and improve the accuracy of feeding. The transportation of the laminated board 3 can be completed by external conveying devices (such as automatic guided vehicles (AGV trolleys), conveyors, etc.). These external devices transport the laminated board 3 to the position of the cache device 1, ensure that the laminated board 3 is placed stably in the cache station 11, and wait for subsequent operation. Through the cooperation of the external conveying device (such as AGV trolley) and the cache device 1, an automatic material conveying process is realized, which greatly improves the work efficiency.

In this step, the buffer device 1 fixes the position of the stack of sheets 3 to prevent the stack of sheets 3 from shifting or sliding during transportation, ensuring that the stack of sheets 3 remains stable in the buffer device 1. The driving method can be electric driving, pneumatic driving, hydraulic driving, etc.

[0064] In an embodiment, the step of the buffer device 1 clamping the stack of sheets 3 specifically includes:

[0065] The buffer device 1 clamps the fixed pin 32 of the stack of sheets 3;

The buffer device 1 can grab the fixed pin 32 through a clamping device such as a clamp, pneumatic clamp, etc., or the buffer device 1 can abut against the fixed pin 32 in the first direction to exert a force on the fixed pin 32 in the first direction, ensuring that the stack of sheets 3 does not shift in the buffer device 1. Through these two clamping methods, the buffer device 1 can ensure that the stack of sheets 3 maintains an accurate position during conveying and docking with the workbench 2, thereby improving production efficiency and accuracy.

[0067] In an embodiment, the buffer device 1 is provided with a material taking assembly. When the buffer device 1 clamps the fixed pin 32, the step of driving the buffer device 1 to move in the first direction to convey the stack of sheets 3 specifically includes:

[0068] The material taking assembly clamps the fixed pin 32;

[0069] The material taking assembly lifts the stack of sheets 3, and the material taking assembly moves in the first direction to drive the stack of sheets 3 to move. In this method, the material taking assembly first lifts the stack of sheets 3, which can be achieved through a mechanical arm, pneumatic lifting device, or electric lifting mechanism, etc. After the material taking assembly lifts the stack of sheets 3, it moves in the first direction, which is usually driven by a driving system such as a motor, air cylinder, servo drive, etc. The movement of the material taking assembly drives the stack of sheets 3 to move synchronously. By lifting the stack of sheets 3, direct contact between the stack of sheets 3 and the buffer device 1 can be avoided, reducing friction and wear, and the stack of sheets 3 can also be conveyed to the workbench 2 more smoothly.

[0070] Alternatively, the material taking assembly moves in the first direction to drag the stack of sheets 3 to move. The material taking assembly drags the stack of sheets 3 to move by moving in the first direction. During the movement of the material taking assembly, the material taking assembly drives the stack of sheets 3 to move forward through clamping force. This method is simple in structure and low in cost.

[0071] In an embodiment, the buffer device 1 is provided with a material moving assembly 13, and the step of driving the buffer device 1 to move along the first direction to abut against the fixed pin 32 includes:

[0072] driving the material moving assembly 13 to move along the first direction to abut against the fixed pin 32;

[0073] driving the material moving assembly 13 to move along the first direction to push the laminated plate 3 to move along the first direction, so that the laminated plate 3 can be smoothly and accurately conveyed from the buffer device 1 to the target position.

[0074] Specifically, referring to Figures 4 to 7 , the material moving assembly 13 includes a limiting driving member 132, a limiting sensor 133, a limiting elastic member 134, a clamping member 135, and a limiting seat 136 provided with a blocking portion 1361; the limiting driving member 132 is connected to the limiting seat 136; it can be understood that the limiting driving member 132 includes but is not limited to a linear motor, a pneumatic cylinder, and a hydraulic cylinder, etc.; the limiting driving member 132 is used to drive the limiting seat 136 to move along the second direction.

[0075] The clamping member 135 is movably connected to the limiting seat 136 and surrounds the blocking portion 1361 to form a limiting slot 131; one end of the limiting elastic member 134 is connected to the limiting seat 136, and the other end is connected to the clamping member 135; the clamping member 135 moves relative to the limiting seat 136 through the limiting elastic member 134, so as to block or open the opening of the limiting slot 131; it can be understood that the limiting elastic member 134 includes but is not limited to a spring, etc., and the limiting sensor 133 includes but is not limited to a laser sensor and a photoelectric sensor, etc.; the blocking portion 1361 and the clamping member 135 are respectively located at opposite ends of the limiting slot 131 along the first direction, and further, the limiting slot 131 is provided with an opening at an end away from the blocking portion 1361 along the first direction; when the clamping member 135 moves upward and compresses the limiting elastic member 134, the clamping member 135 will open the opening of the limiting slot 131; when the limiting elastic member 134 drives the clamping member 135 to move downward, the clamping member 135 will block the opening of the limiting slot 131.

[0076] The limiting sensor 133 is installed on the limiting seat 136 and is used to detect whether the fixed pin 32 is limited in the limiting slot 131; it can be understood that the limiting sensor 133 can be installed on the inner wall of the limiting slot 131.

[0077] Referring to Figures 6 to 8Specifically, the PCB 31 has two fixed pins 32 arranged at intervals along the first direction, and the limiting seat 136 and the clamping member 135 are located above the moving path of the fixed pins 32 during the movement of the PCB 31 along the first direction. After the front fixed pin 32 moves away from directly below the material moving assembly 13, the limiting driving member 132 drives the limiting seat 136 and the clamping member 135 to move downward, and the rear fixed pin 32 moves along the first direction and presses the clamping member 135 upward. The clamping member 135 moves upward and compresses the limiting elastic member 134, and the clamping member 135 opens the limiting groove 131 away from the opening at one end of the blocking part 1361. After the rear fixed pin 32 moves into the limiting groove 131, the limiting elastic member 134 drives the clamping member 135 to move downward, so that the clamping member 135 and the blocking part 1361 limit the fixed pin 32 in the limiting groove 131. During the movement of the material moving assembly 12 along the first direction, the clamping member 135 pushes the fixed pin 32 along the first direction, so as to drive the PCB 31 to move along the first direction. In the embodiment, the limiting sensor 133 can detect whether the fixed pin 32 is in the limiting groove 131 in real time, so as to ensure that the buffering device 1 stably moves the PCB 31 to the workbench 2. It can be understood that those skilled in the art can obtain the corresponding structure of the material moving assembly through some adaptive changes according to the structure of the material moving assembly 13, and the specific structure of the material moving assembly is not described in detail here.

[0078] Please refer to Figures 4 to 6 In an embodiment, the pressing plate of the guide plate assembly 18 is provided with a guide groove 181 and a through groove 182. The guide groove 181 is arranged at one end of the pressing plate away from the supporting plate and penetrates the pressing plate along the first direction.

It can be understood that the guide groove 181 is a long strip-shaped groove arranged at the bottom of the pressing plate, and the through groove 182 is arranged at the top of the pressing plate. When the external device transports the laminated board 3 to the buffering device 1, the fixed 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 fixed pin 32.

[0081] The workbench 2 is driven to move along the first direction;

[0082] The driving buffer device 1 places the laminated plate 3 on the workbench 2. In this embodiment, the laminated plate 3 is accurately positioned in the buffer device 1, preventing displacement or deviation of the laminated plate 3 during transportation. The workbench 2 moves in the first direction to be able to move to the inside of the buffer device 1, ready to receive the laminated plate 3. Among them, the workbench 2 can be driven by motor, pneumatic drive or servo system, accurately moving in the specified direction. The buffer device 1 limits the laminated plate 3, ensuring that the laminated plate 3 can be smoothly and accurately transported from the buffer device 1 to the workbench 2.

[0083] In an embodiment, the buffer device 1 is provided with a taking component, and the step of driving the buffer device 1 to place the laminated plate 3 on the workbench 2 specifically includes:

[0086] driving the workbench 2 to move in the first direction;

[0087] driving the taking component to place the laminated plate 3 on the workbench 2. Through the automatic operation of the taking component, such as clamping the fixing pin 32, lifting the laminated plate 3, moving the workbench 2 and placing the laminated plate 3, the need for manual intervention is greatly reduced, thereby improving the transportation efficiency and the degree of automation.

[0088] In an embodiment, the buffer device 1 is provided with a taking component, and the step of driving the buffer device 1 to place the laminated plate 3 on the workbench 2 specifically includes:

[0089] driving the taking component to clamp the fixing pin 32;

[0090] driving the workbench 2 to move in the first direction;

[0091] The driving buffer device 1 places the laminated plate 3 on the workbench 2. By driving the material taking assembly clamping fixed pin 32, the stability of the laminated plate 3 in the conveying process is realized, and the need for manual fixing or adjustment is avoided, thereby improving the conveying efficiency. The clamping effect of the material taking assembly ensures that the laminated plate 3 will not deviate from the predetermined track due to shaking or sliding during the conveying process, thereby improving the stability of the conveying. In this embodiment, before driving the workbench 2 to move in the first direction, the material lifting roller assembly 21 on the workbench 2 needs to be moved to the raised position. During the movement of the workbench 2 close to the laminated plate 3, the material lifting roller assembly 21 can support the bottom of the laminated plate 3, thereby improving the stability, and the use of rolling friction can effectively reduce the friction, thereby ensuring smooth process and reducing damage. When the laminated plate 3 completely reaches the material changing area, the material lifting roller assembly 21 is moved to the landing position to place the laminated plate 3 on the workbench 2. During this process, the material taking assembly can also apply pressure to the laminated plate 3 to cooperate with the material lifting roller assembly 21 to clamp both ends of the laminated plate 3, thereby ensuring the stability of the laminated plate 3 during movement.

By directly driving the material moving assembly 13 to abut against the fixed pin 32 in the first direction, the fixing and lifting steps of the laminated plate 3 are simplified, and the conveying process is more simple and efficient. Similarly, in this embodiment, before driving the workbench 2 to move in the first direction, the material lifting roller assembly 21 on the workbench 2 needs to be moved to the raised position. During the movement of the workbench 2 close to the laminated plate 3, the material lifting roller assembly 21 can support the bottom of the laminated plate 3, thereby improving the stability, and the use of rolling friction can effectively reduce the friction, thereby ensuring smooth process and reducing damage. When the laminated plate 3 completely reaches the material changing area, the material lifting roller assembly 21 is moved to the landing position to place the laminated plate 3 on the workbench 2. During this process, the material taking assembly can also apply pressure to the laminated plate 3 to cooperate with the material lifting roller assembly 21 to clamp both ends of the laminated plate 3, thereby ensuring the stability of the laminated plate 3 during movement.

[0099] The position of the material taking assembly or the material moving assembly 13 is adjusted so that the material taking assembly or the material moving assembly 13 can limit the other end of the alignment tool 4. It can be understood that the avoidance hole corresponds to the position of the fixing pin 32, and the alignment tool 4 corresponds to the state of simulating the insertion of the fixing pin 32 into the avoidance hole. Through the pre-calibration, the position of the fixing pin 32 is ensured to be accurate, and then the limiting effect of the material taking assembly or the material moving assembly 13 on the fixing pin 32 is ensured, and the stability of transportation is ensured. In the embodiment, the alignment tool 4 cooperates with the workbench 2 and the material taking assembly or the material moving assembly 13 to form a stable position reference system. Once the alignment tool 4 is positioned, the subsequent conveying, placing and other operations of the laminated board 3 can be based on this stable reference, so that the position of the laminated board 3 in the entire feeding process and the subsequent processing process has high consistency.

[0100] In an embodiment, the main machine 5 includes the workbench 2, the workbench 2 is provided with the avoidance hole, and the main machine 5 has the material changing area; before the step of conveying the laminated board 3 to the buffer device, the method further includes:

[0105] According to the feeding method provided by the utility model, the reasonable layout of the buffer device and the host 5 on the equipment structure (such as the layout features of the buffer device 1 at one end of the host 5 mentioned above) makes the operator have relatively independent and appropriate operation space in different stages. For example, when the laminated board 3 is transported to the buffer device 1, the operation of carrying and placing can be conveniently carried out in the corresponding area of the buffer device 1; then when the laminated board 3 is transported to the host 5, the docking action can be smoothly completed at the corresponding position of the host 5, which reduces the inconvenience caused by space constraints and mutual operation interference and optimizes the operation experience. At the same time, the separated feeding steps and the corresponding area setting make it possible to carry out maintenance on one part of the equipment without being disturbed by the feeding operation of the other part. For example, when the host 5 is deeply maintained and repaired, the transportation from the buffer device 1 to the host 5 can be temporarily stopped, and the maintenance work can be carried out in an environment without feeding operation disturbance, which guarantees the quality and safety of the maintenance work and also helps to shorten the maintenance time and reduce the influence of equipment downtime on production.
