[0001] This utility model relates to the field of mechanical transportation technology, and in particular to a buffer mechanism. Background Technology

[0002] As a key part of automated production processes, conveyor lines are used to transfer workpieces from one production process to the next processing equipment, achieving production continuity and automation. When a workpiece on the conveyor line arrives at the processing equipment, it is transferred to the processing equipment by a robotic arm or manually. If the robotic arm cannot remove the workpiece from the conveyor line in a timely and accurate manner, the workpiece will continue to be transported to the next process along the conveyor line, resulting in workpiece loss. Utility Model Content

[0003] The main purpose of this invention is to propose a buffer mechanism to solve the technical problem of workpiece processing omissions caused by the robot arm's inability to grasp the workpiece in time.

[0004] To achieve the above objectives, the cache mechanism proposed in this utility model includes:

[0005] Support frame, installed on the conveyor line;

[0006] A stop assembly is provided on the support frame, and the stop assembly is used to buffer the workpiece on the conveyor line;

[0007] A guide assembly is provided on the conveyor line and located on the side of the support frame facing the feeding direction. The guide assembly is used to guide the workpiece on the conveyor line.

[0008] In one embodiment, the stop assembly includes:

[0009] A linear drive component is provided on the support frame;

[0010] A stop plate is provided, and the linear drive is driven to the stop plate to descend and approach the conveyor line. The stop plate is used to stop the flow of the workpiece on the conveyor line.

[0011] In one embodiment, the conveyor line includes a mounting base and a conveyor belt, the conveyor belt being rotatably mounted on the mounting base; a support frame spans over the conveyor belt and is mounted at both ends on the mounting base, and the linear drive is slidably connected to the support frame.

[0012] In one embodiment, the guiding component includes:

[0013] Two connecting seats are provided, and the two connecting seats are installed on both sides of the conveyor belt and mounted on the mounting base;

[0014] A connecting frame spans across the top of the conveyor belt, and each end is connected to one of the connecting seats;

[0015] Two guide structures are provided, which are spaced apart on the connecting frame and slidably connected to the connecting frame. The opposite side of the two guide structures is used to abut against the two sides of the workpiece.

[0016] In one embodiment, the guide structure includes:

[0017] A first connecting plate is slidably disposed on the connecting frame, and the first connecting plate is parallel to the length direction of the conveyor line;

[0018] A guide plate is disposed at the end of the first connecting plate away from the stop assembly;

[0019] The guide plates of the two guide structures extend at an angle away from each other.

[0020] In one embodiment, the guide assembly further includes a second connecting plate, two of which are provided. Each second connecting plate is connected to the end of a first connecting plate away from the guide plate, and the second connecting plate extends toward the stop assembly.

[0021] In one embodiment, the first connecting plate and the second connecting plate are integrally formed.

[0022] In one embodiment, the guide assembly further includes a mounting block and a fastener. Each guide structure is slidably connected to the connecting frame via a mounting block.

[0024] In one embodiment, the second connecting plate is provided with a mounting groove, and the detection sensor is disposed in the mounting groove and does not protrude from the side wall of the second connecting plate.

[0025] In this invention, a support frame is installed on the conveyor line, a stop assembly is installed on the support frame, and a guide assembly is installed on the conveyor line and on the front side of the support frame. When the conveyor line transports a workpiece, the workpiece first passes through the guide assembly, which adjusts the direction of the workpiece so that its edge is parallel to the conveyor line. This facilitates the subsequent handling by the robot arm, allowing the workpiece to be directly placed on the processing equipment for processing without the need for orientation calibration, thus improving processing accuracy. After passing through the guide assembly, the workpiece reaches the stop assembly, which extends to block the workpiece from continuing to move forward on the conveyor line until the robot arm removes the workpiece. The stop assembly prevents unprocessed workpieces from passing directly through and causing workpiece loss, thus avoiding increased production costs due to workpiece loss. This solution improves workpiece processing efficiency and accuracy while reducing production costs. Attached Figure Description

[0040] As a key part of automated production processes, conveyor lines are used to transfer workpieces from one production process to the next processing equipment, achieving production continuity and automation. When a workpiece on the conveyor line arrives at the processing equipment, it is transferred to the processing equipment by a robotic arm or manually. If the robotic arm cannot remove the workpiece from the conveyor line in a timely and accurate manner, the workpiece will continue to be transported to the next process along the conveyor line, resulting in workpiece loss.

[0041] This utility model proposes a caching mechanism.

[0042] Please see Figure 1In one embodiment of the present invention, the buffering mechanism includes a support frame 100, a stop assembly 200, and a guide assembly 300. The support frame 100 is disposed on the conveyor line 20; the stop assembly 200 is disposed on the support frame 100 and is used to buffer the workpiece 10 on the conveyor line 20; the guide assembly 300 is disposed on the conveyor line 20 and is located on the side of the support frame 100 facing the feeding direction, and is used to guide the workpiece 10 on the conveyor line 20.

[0043] In the technical solution of this utility model, a support frame 100 is set on the conveyor line 20, a stop assembly 200 is set on the support frame 100, and a guide assembly 300 is set on the conveyor line 20 and on the front side of the support frame 100. When the conveyor line 20 transports the workpiece 10, the workpiece 10 first passes through the guide assembly 300. The guide assembly 300 adjusts the direction of the workpiece 10 so that its edge is parallel to the conveyor line 20, which makes it easy for the robot to directly place it on the processing equipment for processing without the need for direction calibration, thus improving the processing accuracy. After passing through the guide assembly 300, the workpiece 10 reaches the stop assembly 200. The stop assembly 200 extends to block the workpiece 10 on the conveyor line 20 from continuing to move forward until the robot takes away the workpiece 10. The setting of the stop assembly 200 can prevent the unprocessed workpiece 10 from passing directly through and causing the workpiece 10 to be missed, and also avoids the increase in production costs caused by the workpiece 10 being missed. The setting of this solution improves the processing efficiency and processing accuracy of the workpiece 10, and also reduces the production cost.

[0044] Specifically, such as Figure 1 and Figure 3As shown, the buffer mechanism is used to position the workpiece 10 on the conveyor line 20. A processing device, such as a dispensing device or a pressing device, is located on one side of the conveyor line 20. When the conveyor line 20 transports the workpiece 10 to a location near the processing device, a robotic arm transfers the workpiece 10 from the conveyor line 20 to the processing device for processing. However, because the conveyor line 20 may not transfer the workpiece 10 in a timely manner, the workpiece 10 may continue to flow downwards along the conveyor line 20. Furthermore, the workpiece 10 may become skewed or offset on the conveyor line 20. This offset workpiece affects the processing accuracy during processing on the processing device. In this solution, the support frame 100 serves as a support structure on the conveyor line 20. The support frame 100 is installed on the conveyor line 20 with screws and other fasteners to ensure that it will not loosen or shift during long-term operation. When the workpiece 10 passes the guide component 300, the guide component 300 guides the workpiece 10 to adjust its direction and finally parallel the length direction of the conveyor line 20. This facilitates accurate directional positioning for subsequent gripping by the robot and also facilitates direct processing on the processing equipment, improving processing accuracy and efficiency. The stop component 200 can be a telescopic baffle to block the workpiece 10 from moving forward when it extends, waiting for the robot or manual transfer, effectively preventing the workpiece 10 from being missed during processing.

[0045] In an embodiment of this utility model, the stop assembly 200 includes:

[0046] Linear drive component 210 is mounted on support frame 100;

[0047] The stop plate 220 is driven by the linear drive 210 to drive the stop plate 220 to descend and approach the conveyor line 20. The stop plate 220 is used to stop the flow of the workpiece 10 on the conveyor line 20.

[0048] Please refer to Figure 1 The stop assembly 200 includes a linear drive component 210 and a stop plate 220. The linear drive component 210 can be a cylinder, hydraulic cylinder, electric telescopic rod, or lead screw and nut assembly, etc., and there are no restrictions. In this embodiment, the linear drive component 210 is a cylinder. The cylinder body is mounted on the support frame 100. The piston rod extends downward and connects to a stop plate 220. The stop plate 220 extends along the width direction of the conveyor line 20. The stop plate 220 can be made of polyurethane or rubber, etc., which has good elasticity and wear resistance. When it contacts the workpiece 10, it can form a certain buffer to avoid scratching the workpiece 10. Optionally, the edge of the stop plate 220 is rounded to reduce the risk of scratching the workpiece 10. The linear drive component 210 drives the stop plate 220 to extend or retract, so as to effectively block the workpiece 10 on the conveyor line 20 and wait for the robot to grab it.

[0049] In an embodiment of this utility model, the conveyor line 20 includes a mounting base and a conveyor belt, the conveyor belt being rotatably mounted on the mounting base; the support frame 100 spans over the conveyor belt and is mounted on the mounting base at both ends, and the linear drive member 210 is slidably connected to the support frame 100.

[0050] Please refer to Figure 1 The mounting base is made of steel, which has a certain rigidity and stability, facilitating the stable movement of the conveyor belt on the mounting base. The conveyor belt is mounted on the mounting base by rotating rollers, and a servo motor is set at one end of the mounting base to drive the rollers to rotate, thereby driving the conveyor belt to transport the workpiece 10. The support frame 100 has a U-shaped structure, including a horizontal aluminum profile and vertical aluminum profiles set at both ends of the horizontal aluminum profile. The horizontal aluminum profile is set above the conveyor belt. The fixed end of the linear drive component 210 slides on the support frame 100 to adjust the position of the linear drive component 210 on the support frame 100, thereby adjusting the position of the stop plate 220. Specifically, the linear drive component 210 can be mounted on a mounting plate. The mounting plate is provided with an elongated hole extending in the vertical direction. Screws and other connecting parts pass through the elongated hole and are screwed to the support frame 100 to adjust the vertical position of the linear drive component 210 to adapt to workpieces 10 of different sizes.

[0051] In an embodiment of this utility model, the guide component 300 includes:

[0052] Two connecting seats 310 are provided, and the two connecting seats 310 are installed on both sides of the conveyor belt and mounted on the mounting base;

[0053] The connecting frame 320 spans across the top of the conveyor belt and is connected to a connecting seat 310 at each end;

[0054] Two guide structures 330 are provided, which are spaced apart on the connecting frame 320 and slidably connected to the connecting frame 320. The opposite side of the two guide structures 330 is used to abut against the two sides of the workpiece 10.

[0055] Please refer to Figure 2The guide assembly 300 includes connecting seats 310 disposed on both sides of the conveyor belt. The connecting seats 310 can be made of aluminum profiles. A connecting frame 320 is connected above the two connecting seats 310. The connecting frame 320 is mounted on the connecting seats 310 by screws or other structures to maintain structural stability and prevent displacement. The connecting frame 320 is higher than the conveyor belt to facilitate the flow of the workpiece 10. Two guide structures 330 are spaced apart on the connecting frame 320. The guide structures 330 are used to guide and adjust the direction of the workpiece 10, so that the two guide structures 330 respectively abut against the two sides of the workpiece 10. The side of the workpiece 10 is parallel to the length of the conveyor line 20. Since the two guide structures 330 can slide on the connecting frame 320, the distance between them can be adjusted to accommodate workpieces 10 of different sizes, meet diverse production needs, and avoid the offset problem caused by the incorrect orientation of the workpiece 10, which affects the processing accuracy. After the orientation of the workpiece 10 is adjusted by the guide component 300, the workpiece 10 can reach the stop component 200 in the correct direction, which makes it easier for the robot to grab the workpiece 10 and reach the processing equipment, improve the processing accuracy and production efficiency, and reduce the production cost.

[0056] In an embodiment of this utility model, the guide structure 330 includes:

[0057] The first connecting plate 331 is slidably disposed on the connecting frame 320, and the first connecting plate 331 is parallel to the length direction of the conveyor line 20;

[0058] Guide plate 332 is located at the end of first connecting plate 331 away from stop assembly 200;

[0059] Among them, the guide plates 332 of the two guide structures 330 extend at an angle away from each other.

[0060] Please refer to Figure 2 The two guide plates 332 are inclined to form a gradually narrowing guide channel, so that the inclined workpiece 10 is guided by the guide plates 332 on the conveyor line 20. The workpiece 10 gathers towards the center, so that the side and length of the workpiece 10 tend to be consistent. When it reaches the first connecting plate 331, the side of the workpiece 10 abuts against the first connecting plate 331 and is parallel to the length of the conveyor line 20. This not only avoids the low processing accuracy caused by the workpiece 10 being in an incorrect posture, but also improves the stability of the conveying.

[0061] Optionally, in one embodiment, an elastic buffer is provided on one side of the two guide plates 332 to reduce the impact force when the workpiece 10 comes into contact with the guide plate 332, thereby reducing damage to the workpiece 10.

[0062] In an embodiment of this utility model, the guide assembly 300 further includes a second connecting plate 340. Two second connecting plates 340 are provided, and each second connecting plate 340 is connected to the end of a first connecting plate 331 away from the guide plate 332. The second connecting plate 340 extends toward the stop assembly 200 and leads to the stop assembly 200. The arrangement of the second connecting plate 340 ensures that the side of the workpiece 10 remains in contact with the second connecting plate 340 after passing through the guide assembly 300, and smoothly reaches the stop assembly 200. When it reaches the stop assembly 200, it remains parallel to the conveyor line 20, avoiding deviation during the conveying process and improving the accuracy and stability of the workpiece 10 conveying.

[0063] Optionally, in one embodiment, the first connecting plate 331 and the second connecting plate 340 are integrally formed to ensure the stability and strength of the structure and avoid loosening when subjected to lateral impact. During the conveying of the workpiece 10, the side can be kept in contact with the second connecting plate 340.

[0064] In an embodiment of this utility model, the guide component 300 further includes a mounting block and a fastener. Each guide structure 330 is slidably connected to the connecting frame 320 via a mounting block. The mounting block has at least one mounting hole. The fastener passes through the mounting hole and is screwed to the connecting frame 320. The mounting block can be made of aluminum alloy. The mounting hole is an elongated hole, allowing the fastener to slide within the mounting hole, thereby adjusting the distance between the two guide components 300 to accommodate workpieces 10 of different sizes.

[0065] In an embodiment of the present invention, the buffer mechanism further includes a detection sensor 400, which is disposed on the side of any second connecting plate 340 facing the other second connecting plate 340, and the detection sensor 400 is disposed near the stop assembly 200.

[0066] Please refer to Figure 1 The detection sensor 400 is used to detect the workpiece 10. When the workpiece 10 reaches the stop assembly 200, the detection sensor 400 detects the workpiece 10 and sends a signal to the controller. The controller drives the linear drive 210 to start, so that the stop plate 220 extends and blocks the workpiece 10 from continuing to flow, effectively preventing the workpiece 10 from being missed.

[0067] Optionally, in one embodiment, the second connecting plate 340 is provided with a mounting groove 341, and the detection sensor 400 is disposed in the mounting groove 341 and does not protrude from the side wall of the second connecting plate 340. The mounting groove 341 can ensure that the detection sensor 400 can detect the arrival of the workpiece 10, and can also prevent the detection sensor 400 from obstructing the flow of the workpiece 10 and affecting the processing accuracy of the workpiece 10.

[0068] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
