Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a feeding mechanism with high stable transmission, belonging to the field of lens component assembly technology. Background Technology

[0002] Currently, most mainstream lens component loading mechanisms in the industry use mechanical clamps to hold the components, then use cylinders to drive the clamps to lift and hold them, and finally use a translation mechanism to control the horizontal movement of the components to reciprocate the loading of the components.

[0003] However, during the lifting and clamping process, traditional mechanisms require additional detection components such as photoelectric sensors and laser displacement encoders to monitor the height position of the cylinder in real time, which increases the hardware cost of the equipment. Moreover, the cylinder itself does not have position feedback and self-calibration capabilities, and only relies on air source pressure to control lifting and lowering. It is very easy for the lifting height to deviate due to air source fluctuations, which in turn causes the clamp and component to be misaligned, resulting in delayed position calibration and further affecting the feeding efficiency.

[0004] To address these issues, a highly stable feeding mechanism was designed. Utility Model Content

[0005] The main objective of this invention is to provide a feeding mechanism with highly stable transmission to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A highly stable feeding mechanism includes a linear conveyor belt and a frame vertically mounted on top of the linear conveyor belt. A mounting plate is provided on one side of the frame, and a horizontal conveying mechanism is provided on the outer side of the frame to control the mounting plate to slide back and forth along the length of the frame.

[0008] A sliding plate is vertically mounted on the outer side of the mounting plate. A pneumatic chuck is mounted on the bottom of the sliding plate. A vertical rod is vertically mounted on the top of the sliding plate. A guide rod is mounted on the side of the vertical rod closest to the mounting plate. A strip groove is vertically opened on the top of the mounting plate.

[0009] A fixed plate is provided on the top of the frame along the length direction. The fixed plate has a guide groove that matches the movement path of the pneumatic chuck. The end of the guide rod passes through the strip groove and extends into the guide groove.

[0010] Preferably, the guide channel includes an inclined section and a horizontal section, the inclined section and the horizontal section are connected end to end, and the connection between the inclined section and the horizontal section is arc-shaped. The height variation of the inclined section is adapted to the material picking and feeding height of the lens element, and the length of the horizontal section is adapted to the conveying distance of the lens element.

[0011] Preferably, the horizontal conveying mechanism includes a chute, a slider, a screw, and a motor. The chute is opened along the length direction on the outside of the frame. The slider is slidably arranged inside the chute and is fixedly connected to the mounting plate. The screw is rotatably installed between the two ends of the chute and is threadedly connected to the slider. The motor is installed at the end of the frame and the output end of the motor is connected to the screw.

[0012] Preferably, the end of the guide rod is rotatably connected to the vertical rod via a bearing, and the surface of the guide rod is coated with a wear-resistant coating.

[0013] Preferably, a guide rail is vertically fixed to the bottom of the outer side of the mounting plate, and a groove adapted to the guide rail is provided on the side of the slide plate.

[0014] Preferably, the linear conveyor belt is located at one end of the bottom of the frame, and the discharge end of the linear conveyor belt corresponds to the material picking position of the pneumatic chuck, so as to realize continuous feeding of lens components.

[0015] Preferably, both ends of the bottom of the frame are provided with positioning plates, and the positioning plates are provided with mounting holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model features a fixed plate along the length of the top of the frame, with guide grooves on the fixed plate that align with the movement path of the components. This, combined with the vertical rods on the top of the slide plate and the guide rods, forms a collaborative structure. During the reciprocating movement of the mounting plate driven by the horizontal conveying mechanism, the guide rods can adaptively slide along the inside of the guide grooves, thereby directly controlling the pneumatic chuck to achieve automatic lifting and lowering. This design completely eliminates the need for external detection components required by traditional mechanisms, saving on the procurement and installation costs of detection parts and reducing overall equipment investment. Furthermore, by adopting a purely mechanical transmission logic, it avoids the failure risks of electronic detection components and the inherent susceptibility of traditional pneumatic control to air source fluctuations, ensuring controllable lifting and lowering accuracy of the pneumatic chuck and fundamentally guaranteeing the stability of the lens components during transmission.

[0018] 2. This utility model uses a horizontal conveying mechanism composed of a chute, a slider, a screw, and a motor. The screw drive has higher displacement resolution, and with the stable output of the motor, the reciprocating movement distance and speed of the mounting plate can be precisely controlled to achieve millimeter-level horizontal positioning accuracy.

[0031] Example 1

[0032] like Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, this embodiment proposes a feeding mechanism with high stability transmission, including a linear conveyor belt 1 and a frame 2 vertically arranged on the top of the linear conveyor belt 1. A mounting plate 3 is provided on one side of the frame 2, and a horizontal conveying mechanism 4 is provided on the outside of the frame 2 to control the mounting plate 3 to slide back and forth along the length of the frame 2.

[0033] A sliding plate 5 is vertically slidably mounted on the outer side of the mounting plate 3. A pneumatic chuck 6 is mounted on the bottom of the sliding plate 5. A vertical rod 7 is vertically mounted on the top of the sliding plate 5. A guide rod 8 is mounted on the side of the vertical rod 7 close to the mounting plate 3. A strip groove 9 is vertically opened on the top of the mounting plate 3.

[0034] A fixing plate 10 is provided on the top of the frame 2 along the length direction. A guide groove 11 is provided on the fixing plate 10 to match the moving path of the pneumatic chuck 6. The end of the guide rod 8 passes through the strip groove 9 and extends into the guide groove 11.

[0035] Working principle: First, the linear conveyor belt 1 is started, which continuously transports the lens components to be assembled to the preset material picking station. The discharge end of the linear conveyor belt 1 corresponds precisely to the material picking position of the pneumatic chuck 6, providing a continuous and stable supply of components for subsequent material picking. Then, the horizontal conveying mechanism 4 is started, which generates driving force to drive the mounting plate 3, which is matched with it, to slide back and forth along the length of the frame 2. The sliding direction of the mounting plate 3 directly determines the subsequent movement trajectory of the pneumatic chuck 6, providing the power basis for the horizontal displacement of material picking and feeding.

[0036] During the sliding process of the mounting plate 3, a vertical rod 7 is installed on the top of the sliding plate 5, which is vertically slidable on its outer side. The guide rod 8 of the vertical rod 7 near the mounting plate 3 passes through the strip groove 9 opened on the top of the mounting plate 3 and extends into the guide groove 11 on the top fixing plate 10 of the frame 2. Since the trajectory of the guide groove 11 is perfectly matched with the moving path of the pneumatic chuck 6, when the mounting plate 3 moves the guide rod 8 horizontally, the guide rod 8 will slide adaptively along the inner wall of the guide groove 11. The change in the trajectory of the guide groove 11 will be transmitted to the vertical rod 7 through the guide rod 8, thereby causing the sliding plate 5 at the bottom of the vertical rod 7 to move vertically along the outer side of the mounting plate 3. During the lifting and lowering motion, when the slide plate 5 is raised and lowered vertically, the pneumatic chuck 6 installed at its bottom is raised and lowered synchronously. When the pneumatic chuck 6 descends with the slide plate 5 to the material picking station, the pneumatic chuck 6 starts and clamps the lens element conveyed by the linear conveyor belt 1. Subsequently, the horizontal conveying mechanism 4 continues to drive the mounting plate 3 to move towards the feeding station. The guide rod 8 slides along the guide groove 11 to keep the pneumatic chuck 6 at the appropriate conveying height until it reaches the feeding station. Then, the pneumatic chuck 6 releases, completing the feeding of the lens element. Finally, the horizontal conveying mechanism 4 drives the mounting plate 3 to reset and enter the next material picking-feeding cycle.

[0037] Example 2

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 1 As shown, in a preferred embodiment, based on the above method, the guide groove 11 further includes an inclined section and a horizontal section, the inclined section and the horizontal section are connected end to end, and the connection between the inclined section and the horizontal section is arc-shaped. The height change of the inclined section is adapted to the material picking and feeding height of the lens element, and the length of the horizontal section is adapted to the conveying distance of the lens element.

[0040] When picking up materials, the guide rod 8 moves to the bottom of the inclined section. After reaching the picking position, the pneumatic chuck 6 is activated to clamp the component and then feed it. After the guide rod 8 rises along the inclined section to the horizontal section and moves horizontally to the feeding position, the pneumatic chuck 6 is opened again to release the material.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, the horizontal conveying mechanism 4 further includes a chute 401, a slider 402, a screw 403, and a motor 404. The chute 401 is opened along the length direction on the outside of the frame 2. The slider 402 is slidably arranged inside the chute 401. The slider 402 is fixedly connected to the mounting plate 3. The screw 403 is rotatably installed between the two ends of the chute 401, and the screw 403 is threadedly connected to the slider 402. The motor 404 is installed at the end of the frame 2, and the output end of the motor 404 is connected to the screw 403.

[0042] After the motor 404 is started, the output end of the motor 404 drives the screw 403 in the slide groove 401 to rotate. Since the screw 403 is threadedly connected to the slider 402, and the slider 402 is fixedly connected to the mounting plate 3 and the slider 402 is limited to the slide groove 401 and cannot rotate, the rotational motion of the screw 403 is converted into the linear sliding of the slider 402 along the length direction of the slide groove 401, thereby driving the mounting plate 3 to move smoothly.

[0043] like Figure 2 As shown, in a preferred embodiment, based on the above method, the end of the guide rod 8 is rotatably connected to the vertical rod 7 through a bearing, and the surface of the guide rod 8 is coated with a wear-resistant coating. When the guide rod 8 slides along the guide groove 11, the bearing converts the sliding friction into rolling friction, reducing the frictional resistance between the guide rod 8 and the inner wall of the guide groove 11. At the same time, the wear-resistant coating on the surface of the guide rod 8 can reduce the wear caused by long-term sliding and extend the service life of the guide rod 8.

[0044] like Figure 2As shown, in a preferred embodiment, based on the above method, a guide rail 12 is vertically fixed to the bottom of the outer side of the mounting plate 3, and a groove adapted to the guide rail 12 is opened on the side of the slide plate 5. When the slide plate 5 is raised or lowered, the groove slides along the guide rail 12. The guide rail 12 plays a limiting and guiding role on the movement trajectory of the slide plate 5, so as to prevent the slide plate 5 from shifting left or right during vertical sliding and to ensure the accurate raising and lowering trajectory of the pneumatic chuck 6.

[0045] like Figure 1 As shown, in a preferred embodiment, based on the above method, the linear conveyor belt 1 is further located at one end of the bottom of the frame 2, and the discharge end of the linear conveyor belt 1 corresponds to the material picking position of the pneumatic chuck 6, so as to realize continuous feeding of lens components.

[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, both ends of the bottom of the frame 2 are provided with positioning plates, and the positioning plates are provided with mounting holes. The frame 2 is fixed to the workbench or production line by bolts passing through the mounting holes, so as to prevent the feeding mechanism from shifting as a whole due to vibration during operation and to provide a stable foundation support for the entire transmission process.

[0047] Example 3

[0048] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0049] Before use, securely install the frame 2 at the preset workstation using bolts through the mounting holes on the bottom positioning plate of the frame 2. Ensure the precise relative position of the entire feeding mechanism with other equipment on the production line to avoid overall displacement during operation. During use, start the linear conveyor belt 1. The linear conveyor belt 1 continuously transports the lens components to be processed to the picking station at a preset speed. Its discharge end is precisely aligned with the initial picking position of the pneumatic chuck 6, providing a continuous and stable source of components for subsequent picking and ensuring feeding efficiency. Then, start the motor 404 in the horizontal conveyor mechanism 4. The output end of motor 404 drives screw 403 to rotate in slide groove 401. Screw 403 drives slider 402 to slide along slide groove 401 towards the material picking station through thread transmission. Slider 402 synchronously drives mounting plate 3 to move. During the movement of mounting plate 3, guide rod 8 on vertical rod 7 slides down along the inclined section of guide groove 11. Guide rod 8 drives slide plate 5 to descend vertically along guide rail 12 through vertical rod 7. Pneumatic chuck 6 at the bottom of slide plate 5 descends to the material picking height. When pneumatic chuck 6 reaches directly above lens element, pneumatic chuck 6 starts and clamps the element to complete material picking.

[0050] After material is picked up, motor 404 continues to drive screw 403 to rotate, and slider 402 drives mounting plate 3 to move towards the feeding station. At this time, guide rod 8 enters the horizontal section along the feeding inclined section of guide groove 11. The height of the horizontal section is constant, so that slide plate 5 maintains its current height. The lens element clamped by pneumatic chuck 6 is transported smoothly in the horizontal direction to avoid the element shaking or falling during the transport process. When mounting plate 3 drives pneumatic chuck 6 to the feeding station, pneumatic chuck 6 is released and the lens element is accurately placed in the feeding station. After the feeding is completed, motor 404 reverses and drives screw 403 to rotate in the opposite direction. Components such as slider 402, mounting plate 3, slide plate 5, vertical rod 7, guide rod 8, and pneumatic chuck 6 are reset to the initial picking position along the original path and enter the next picking-conveying-feeding cycle to realize the continuous and highly stable transmission of lens elements.

[0051] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
