Description

Technical Field

[0001] This utility model relates to the field of production technology, and more specifically, to an alternating feeding mechanism and a production line. Background Technology

[0002] Currently, most inclined vertical PCB feeding and unloading machines on the market use a single-station feeding method. Therefore, during the unloading process, after the PCBs in the inclined vertical rack at the workstation are completely released, the operator needs to manually pull the empty rack out of the workstation and place it on a transfer cart. Then, the fully loaded rack is pushed from another transfer cart to the workstation. During the unloading process, after the rack at the workstation is loaded, the operator also needs to manually remove the fully loaded rack and replace it with an empty rack.

[0003] However, the inventors discovered that during the aforementioned rack replacement process, after a rack completes the release or loading of a PCB board, it must be manually replaced. During this period, the equipment is in a waiting state and cannot achieve continuous feeding or recycling operations, causing production line interruptions. Utility Model Content

Detailed Implementation

[0030] In related technologies, existing inclined vertical board feeding and unloading machines generally adopt a single-station feeding method. After a PCB board is released or loaded on a material rack, the material rack must be replaced manually. During this period, the equipment is in a waiting state and cannot achieve continuous feeding or recycling operations, causing production line interruption.

[0031] To address the aforementioned problems, this utility model provides an alternating feeding mechanism and production line, which can ensure the continuous operation of the production line and improve production efficiency and equipment utilization.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] The following describes in detail the alternating feeding mechanism 10 and the overall structure, working principle and technical effects of the production line provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0039] Please see Figures 1 to 3 This utility model provides an alternating feeding mechanism 10, which is applied in a production line (especially in a PCB board production line). It can ensure the continuous operation of the production line and improve production efficiency and equipment utilization. The alternating feeding mechanism 10 includes a frame 100, a moving component 300, a driving element 500, and two buffer components 700.

[0040] The moving component 300 is slidably connected to the frame 100, and the moving component 300 is provided with a first conveyor 311 and a second conveyor 313 side by side. It is understood that the bearing surfaces of both the first conveyor 311 and the second conveyor 313 are used to place the material rack 20, which can specifically be an inclined vertical material rack 20 for carrying PCB boards. The driving element 500 is connected to the moving component 300 and is used to drive the moving component 300 to switch between a first position and a second position.

[0041] Based on the above, when the moving component 300 is in the first position, the first conveyor 311 is in the working position, and the material rack 20 placed on it can be used for receiving or placing plates. At the same time, the second conveyor 313 is in the replacement position, and the material rack 20 placed on it can be replaced by the operator. When the moving component 300 is in the second position, the second conveyor 313 is in the working position to continue the operation process, and the first conveyor 311 is in the replacement position for replacing the subsequent material rack 20.

[0042] It is understandable that, depending on the actual production efficiency requirements, one, two, or more material racks 20 can be installed on the first conveyor 311. Accordingly, when the moving component 300 is in the first position and the first conveyor 311 is in the working position, each material rack 20 on the first conveyor 311 can perform plate loading or unloading operations. This application does not impose specific limitations on this, and it can be flexibly configured according to the actual application scenario.

[0043] Furthermore, both buffer components 700 are mounted on the frame 100 and located on opposite sides of the sliding component 300 in the sliding direction, respectively, to buffer and decelerate the moving component 300, enabling it to smoothly stop at the first or second position. Specifically, one buffer component 700 is used to decelerate and buffer the moving component 300 when it moves to the first position, achieving flexible braking; while the other buffer component 700 is used to decelerate and buffer the moving component 300 when it moves to the second position, achieving flexible braking.

[0044] In other words, the alternating feeding mechanism 10 provided by this utility model, by setting a dual-station structure, can sequentially switch different material racks 20 to workstations for operation without interrupting equipment operation. That is, after the material rack 20 at one workstation completes the board feeding or unloading operation, the system can quickly switch to the material rack 20 at another workstation to continue operation, thereby effectively avoiding production line stagnation caused by material supply interruption, and significantly improving the continuity of the production process, operating efficiency and automation level.

[0045] Please see Figure 4 In some optional embodiments, to improve the guiding stability and running accuracy of the moving component 300 during the switching process, the alternating feeding mechanism 10 also includes a linear guide pair 200, through which the moving component 300 is slidably connected to the frame 100.

[0046] Specifically, the linear guide pair 200 includes a guide rail 210 and a slider 230. The guide rail 210 is fixed to the frame 100 and extends laterally. The slider 230 is slidably connected to the guide rail 210 and fixedly connected to the moving component 300. Based on the above, under the support of the slider 230 and the guidance of the guide rail 210, the moving component 300 can achieve rapid and stable position switching under the action of the driving element 500.

[0047] In other embodiments, the top of the frame 100 may be provided with a track extending laterally, and the moving component 300 is provided with a groove that matches the track, so that the two can slide together directly, reducing manufacturing costs.

[0048] Please refer to it again. Figure 4The drive element 500 includes a piston rod 530 and a cylinder seat 510. The cylinder seat 510 is connected to the frame 100, and the piston rod 530 slides in engagement with the cylinder seat 510. It is understood that the piston rod 530 can reciprocate relative to the cylinder seat 510 under the drive of compressed air or hydraulic pressure, thereby driving the moving component 300 to switch between a first position and a second position.

[0049] Specifically, the moving assembly 300 includes a moving platform 310 and a connecting seat 330. Corresponding to the foregoing, the moving platform 310 is provided with a first conveying member 311 and a second conveying member 313 in parallel. The connecting seat 330 connects the moving platform 310 and the piston rod 530, thereby allowing the moving platform 310 to switch positions synchronously with the extension and retraction of the piston rod 530.

[0050] Furthermore, the alternating feeding mechanism 10 also includes a floating joint 410, through which the connecting seat 330 is connected to the piston rod 530. It should be noted that the floating joint 410 allows for a certain range of offset compensation between the piston rod 530 and the connecting seat 330 during assembly or movement, thereby effectively mitigating rigid interference problems caused by assembly errors or asynchronous movement, and improving the reliability and operational stability of the structural connection.

[0051] Furthermore, the alternating feeding mechanism 10 also includes a hinge assembly 430, through which the cylinder seat 510 is hinged to the frame 100. It is understood that the hinge assembly 430 allows the cylinder seat 510 to adjust its angle and oscillate adaptively within a certain range, thereby reducing vibration and impact caused by uneven force or motion deviation, and improving the smoothness of the overall movement and the reliability of equipment operation. Optionally, the hinge assembly 430 is a single-ear double-earshaft hinge pair structure, suitable for flexible connection requirements under various installation conditions.

[0052] Please see Figure 5 The buffer assembly 700 includes a fixed base 710 and a hydraulic buffer 730; wherein, the fixed base 710 is connected to the frame 100, and the hydraulic buffer 730 is connected to the fixed base 710, and is used to decelerate and buffer the moving assembly 300. With the above configuration, when the moving assembly 300 approaches its end point of travel, the hydraulic buffer 730 can provide a gradually increasing reverse damping force to achieve flexible braking, thereby effectively absorbing kinetic energy, reducing impact force, and enabling the moving assembly 300 to smoothly stop at the target position (first position or second position).

[0053] To further improve the positioning reliability of the moving component 300 during the switching process, the buffer component 700 also includes a limiting structure 750, which is connected to the fixed base 710. Furthermore, the distance between the limiting structure 750 and the moving component 300 is greater than the distance between the hydraulic buffer 730 and the moving component 300, thereby achieving orderly coordination between buffering and positioning and avoiding stress superposition problems that may be caused by the simultaneous action of the two.

[0054] Based on this, during the switching process of the moving component 300, the hydraulic buffer 730 first decelerates and buffers it to achieve flexible braking; then, the limiting structure 750 provides the final rigid limiting support, thereby ensuring that the moving component 300 accurately stops at the target position, while effectively preventing equipment damage caused by overtravel or malfunction, and improving the overall safety and stability of operation.

[0055] Please refer to it again. Figure 5 The limiting structure 750 includes a bolt 751 and a nut 753. The bolt 751 passes through the nut 753 and connects to the fixed base 710. It is understood that the limiting structure 750, composed of the bolt 751 and the nut 753, has the advantages of simple structure and convenient assembly. Furthermore, by adjusting the screw depth of the bolt 751 in the nut 753, the relative position between the limiting structure 750 and the moving component 300 can be flexibly adjusted.

[0056] In summary, this utility model provides an alternating feeding mechanism 10, which includes a frame 100, a moving component 300, a driving element 500, and two buffer components 700. The moving component 300 is slidably connected to the frame 100 and has a first conveyor 311 and a second conveyor 313 arranged in parallel. The driving element 500 is connected to the moving component 300 and drives it to switch between a first position and a second position. When the moving component 300 is in the first position, the first conveyor 311 is in the working position, and the second conveyor 313 is in the changing position. When the moving component 300 switches to the second position, the second conveyor 313 enters the working position, while the first conveyor 311 enters the changing position. The two buffer components 700 are respectively disposed on both sides of the moving component 300 in the sliding direction, and are used to decelerate and buffer when it approaches the end of its stroke, achieving flexible braking and allowing it to smoothly stop at the target position. Based on the above dual-station structure design, different material racks 20 can be quickly switched without interrupting equipment operation, effectively avoiding production line stagnation caused by material supply interruption, and significantly improving production continuity, operating efficiency and automation level.

[0057] In addition, this utility model also provides a production line, which includes a material rack 20 and an alternating feeding mechanism 10 as described in the previous embodiment. Specifically, there are two material racks 20, one of which is located on the first conveyor 311 and the other is located on the second conveyor 313. Accordingly, on this production line, when one material rack 20 is in the working position for receiving or releasing plates, the other material rack 20 is in the switching position, allowing operators to replace or replenish materials on the material rack 20. By alternately switching the working states of the two material racks 20, a seamless connection of the feeding process is achieved, thereby effectively improving the production line operating efficiency and the degree of equipment automation.

[0058] In some optional embodiments, when the moving component 300 switches from the first position to the second position (or from the second position back to the first position), the production line may automatically issue a prompt message (e.g., flashing lights or sounding a buzzer) to remind on-site personnel to promptly replace the material rack 20 on the conveyor in the replacement position.

[0059] It should be added that, such as Figure 3 As shown, after the material rack 20 completes the plate receiving or releasing operation, the operator must first bring the transfer tool 30 close to the frame 100 and manually lock its position; then manually remove the material rack 20 to be replaced onto the transfer tool 30, unlock it, and push the transfer tool 30 aside; then bring another transfer tool 30 loaded with the new material rack 20 close to the frame 100 and manually lock it as well; finally, manually push the new material rack 20 onto the bearing surface of the conveyor, thus completing one material rack 20 replacement operation.

[0060] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
