Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a feeding mechanism for finished product assembly, belonging to the field of camera processing technology. Background Technology

[0002] In the field of automated production of lens modules, in order to achieve efficient and continuous operation, a turntable assembly station is usually used to complete the assembly of lens modules. After the assembly process is completed, the assembled lens modules need to be clamped by a robotic arm, transferred and placed on the surface of a conveyor belt, and then the conveyor belt transports the lens modules to the subsequent process or the finished product storage area.

[0003] Due to limitations imposed by the robotic arm's movement trajectory, the height difference between the workstation and the conveyor belt, and the structure of the gripping end, there is a drop height between the module and the conveyor belt when the robotic arm releases the module, causing two major problems:

[0004] First, the module is easily affected by release shaking, airflow or uneven conveyor belt during descent, causing horizontal displacement. If it exceeds the width of the conveyor belt, it will fall, requiring manual shutdown for handling, and may also cause cosmetic damage.

[0005] Secondly, the falling modules impact the conveyor belt. The internal optical lenses and lens mounts are made of brittle materials and have an assembly precision of micron level. The impact can easily cause scratches, chipping, or misalignment of the assembly precision, resulting in optical performance failure, increasing the defect rate and production costs.

[0006] Currently, the industry has not yet developed an effective solution to the problems caused by this drop height, which has become a bottleneck restricting the production efficiency and quality stability of lens modules. To address this issue, a material unloading mechanism for finished product assembly is designed to optimize the above problems. Utility Model Content

[0007] The main objective of this invention is to provide a material discharge mechanism for finished product assembly, in order to solve the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A discharge mechanism for finished product assembly includes a frame, a conveyor belt located at the top of the frame and arranged along its length, and a drive motor installed at the end of the frame to drive the conveyor belt. A corrugated guide plate is provided at the end of the frame and at the top of the conveyor belt, and side guard plates are symmetrically arranged on both sides of the corrugated guide plate.

[0010] A buffer mechanism is provided between the bottom of the corrugated guide plate and the side of the frame to absorb the impact force when the lens assembly falls.

[0011] The frame is equipped with translation mechanisms on both sides near the end of the corrugated guide plate to adjust the horizontal position of the corrugated guide plate.

[0012] A guide mechanism is provided at the end of the frame away from the corrugated guide plate to guide the lens module if it falls.

[0013] Preferably, the buffer mechanism includes a vertical plate, a sliding rod, and a spring. The vertical plate is vertically installed on both sides of the end of the frame. A sliding rod is vertically slidably installed on the top of each vertical plate. The top of the sliding rod is fixedly connected to a corrugated guide plate. The spring is sleeved on the outside of the sliding rod.

[0014] Preferably, the translation mechanism includes a chute, a slider, and a first positioning bolt. The chute is opened along the length of the frame. A slider is slidably arranged inside the chute. The first positioning bolt is installed on the side of the slider and passes through the slider and abuts against the inner wall of the chute. The bottom end of the vertical plate is fixedly connected to the slider.

[0015] Preferably, the guiding mechanism includes a mounting plate, an L-shaped guide plate, a second positioning bolt, and a through hole. The mounting plate is attached to the outer side of the end of the frame, and the L-shaped guide plate is fixed to the inner side of the mounting plate. The end of the mounting plate has a through hole, and the second positioning bolt passes through the through hole and is threaded to the frame.

[0016] Preferably, the inner wall of the corrugated guide plate is provided with a flexible buffer layer, which is made of silicone material, to prevent scratch damage when the lens module comes into contact with the inner wall of the corrugated guide plate.

[0017] Preferably, the height of the side guard plate is not less than the thickness of the lens module, and the side of the side guard plate facing the conveyor belt has a rounded transition structure to reduce the impact stress when the lens module collides with the side edge of the side guard plate.

[0018] Preferably, the top of the vertical plate has two sets of sliding rods, and the line connecting the two sets of sliding rods is parallel to the length direction of the frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model, by setting a corrugated guide plate at the front end of the frame and the top of the conveyor belt, can directly receive the lens module released by the robotic arm and guide the module's posture along the length of the conveyor belt. This effectively prevents the module from rolling to the side due to release shaking, airflow, or unevenness of the conveyor belt, reducing the loss of manual downtime for handling fallen modules. At the same time, the buffer mechanism at the bottom of the corrugated guide plate, composed of a vertical plate, a sliding rod, and a spring, can efficiently absorb the kinetic energy of the falling module, preventing scratches and chipping of the internal brittle optical lenses and lens mounts due to hard impacts, preventing micron-level assembly precision deviations, fundamentally reducing the risk of optical performance failure, significantly reducing the defect rate, solving the industry pain point of "impact damage restricting quality stability," and directly controlling production costs.

[0021] 2. This utility model relies on a translation mechanism composed of a slide groove, a slider, and a first positioning bolt to achieve flexible adjustment of the position of the corrugated guide plate. The slider can slide along the slide groove and be adjusted to match the falling position of the robotic arm. After that, it is locked and fixed by the first positioning bolt. Without replacing the core components of the mechanism, it can adapt to the material output requirements of robotic arms at different workstations, reduce the investment cost of special equipment, reduce production interruptions caused by workstation adjustments, and improve the versatility of the equipment in multi-specification and multi-workstation production scenarios.

[0022] 3. This utility model further optimizes the lens module unloading process through a guiding mechanism composed of an mounting plate, an L-shaped guide plate, a second positioning bolt, and through holes. The L-shaped guide plate can be adjusted in angle by the second positioning bolt to accurately guide the module's posture when it is transferred from the conveyor belt, avoiding displacement deviation. At the same time, the guiding mechanism can help buffer the impact force during module transfer, forming a synergistic protection with the buffer mechanism at the bottom of the corrugated guide plate, ensuring the stability of the module throughout the entire process from release to conveying, greatly improving the practical value of the mechanism in actual production, and adapting to the high precision and high stability requirements of automated lens module production.

[0036] Example 1

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a discharge mechanism for finished product assembly, including a frame 1, a conveyor belt 2 located at the top of the frame 1 and arranged along its length, and a drive motor 3 installed at the end of the frame 1 to drive the conveyor belt 2. A corrugated guide plate 4 is provided at the end of the frame 1 and at the top of the conveyor belt 2, and side guard plates 5 are symmetrically arranged on both sides of the corrugated guide plate 4.

[0038] A buffer mechanism 6 is provided between the bottom of the corrugated guide plate 4 and the side of the frame 1 to absorb the impact force when the lens assembly falls.

[0039] The frame 1 is provided with translation mechanisms 7 on both sides near the end of the corrugated guide plate 4 to adjust the horizontal position of the corrugated guide plate 4.

[0040] A guide mechanism 8 is provided at the end of the frame 1 away from the corrugated guide plate 4 to guide the lens module when it falls.

[0041] After the drive motor 3 starts, it will drive the conveyor belt 2 at the top of the frame 1 to run along the length of the frame 1, providing power for the subsequent transport of the lens module. When the lens module is released from the assembly station by the robotic arm, due to the height difference between the robotic arm and the conveyor belt 2, the module will first fall onto the corrugated guide plate 4 at the end of the frame 1 and located at the top of the conveyor belt 2. The special structure of the corrugated guide plate 4 can guide the module to adjust its posture along the running direction of the conveyor belt 2, avoiding disordered displacement of the module due to shaking during release, airflow interference, or unevenness of the surface of the conveyor belt 2. At the same time, the side guards 5 symmetrically arranged on both sides of the corrugated guide plate 4 can restrict the range of motion of the module laterally, preventing the module from rolling to the side of the conveyor belt 2 and reducing the frequency of manual shutdown to handle fallen modules.

[0042] During this process, the buffer mechanism 6, which connects the bottom of the corrugated guide plate 4 to the side of the frame 1, absorbs the impact force generated when the module falls, preventing the module from directly impacting the conveyor belt 2. The translation mechanism 7 on both sides of the frame 1 near the corrugated guide plate 4 can flexibly adjust the horizontal position of the corrugated guide plate 4 according to the actual discharge position of the robotic arm, ensuring that the module can accurately land on the corrugated guide plate 4. The guide mechanism 8 on the side of the frame 1 away from the corrugated guide plate 4 will further guide the module's posture when the module is transferred from the conveyor belt 2 to the subsequent process, preventing the module from having displacement deviation at the end of the conveyor, and finally achieving the initial stable connection of the lens module from release to conveyor.

[0043] Example 2

[0044] The solution in Example 1 will be further described below with reference to its specific working method.

[0045] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the buffer mechanism 6 further includes a vertical plate 601, a sliding rod 602 and a spring 603. The vertical plate 601 is vertically arranged on both sides of the end of the frame 1. The top of the vertical plate 601 is vertically slidably provided with a sliding rod 602. The top of the sliding rod 602 is fixedly connected to the corrugated guide plate 4. The spring 603 is sleeved on the outside of the sliding rod 602.

[0046] When the lens module falls onto the corrugated guide plate 4, its own weight and kinetic energy exert downward pressure on the guide plate 4, causing it to move the top-connected slide rod 602 downwards along the vertical sliding path of the vertical plate 601. At this time, the spring 603, sleeved on the outside of the slide rod 602, is compressed due to the slide rod's downward movement. The elastic force of the spring 603 counteracts part of the impact force, converting the module's kinetic energy into the spring's elastic potential energy, thus significantly reducing the hard impact on the module. After the impact energy is absorbed, the spring 603 returns to its original position due to its elasticity, pushing the slide rod 602 upwards along the vertical plate 601, thereby causing the corrugated guide plate 4 to return to its initial position, ready to receive the next lens module.

[0047] like Figure 2 As shown, in a preferred embodiment, based on the above method, the translation mechanism 7 further includes a slide groove 701, a slider 702 and a first positioning bolt 703. The slide groove 701 is opened along the length direction of the frame 1. The slider 702 is slidably arranged inside the slide groove 701. The first positioning bolt 703 is installed on the side of the slider 702, and the first positioning bolt 703 passes through the slider 702 and abuts against the inner wall of the slide groove 701. The bottom end of the vertical plate 601 is fixedly connected to the slider 702.

[0048] When the position of the corrugated guide plate 4 needs to be adjusted, first loosen the first positioning bolt 703 on the side of the slider 702, so that the first positioning bolt 703 is no longer in contact with the inner wall of the slide groove 701. At this time, the slider 702 can slide freely along the slide groove 701 (along the length of the frame 1) on the frame 1. Since the bottom end of the vertical plate 601 is fixedly connected to the slider 702, the sliding of the slider 702 will drive the vertical plate 601, the buffer mechanism 6, and the corrugated guide plate 4 to move synchronously. After the corrugated guide plate 4 moves to the preset position that matches the discharge position of the robotic arm, tighten the first positioning bolt 703 so that the first positioning bolt 703 passes through the slider 702 and abuts tightly against the inner wall of the slide groove 701. The position of the slider 702 is locked by friction, thereby fixing the horizontal position of the corrugated guide plate 4. Different working conditions can be adapted without replacing the core components.

[0049] like Figure 4 As shown, in a preferred embodiment, based on the above method, the guide mechanism 8 further includes a mounting plate 801, an L-shaped guide plate 802, a second positioning bolt 803, and a through hole 804. The mounting plate 801 is attached to the outer side of the end of the frame 1, and the L-shaped guide plate 802 is fixed to the inner side of the mounting plate 801. The end of the mounting plate 801 is provided with a through hole 804, and the second positioning bolt 803 passes through the through hole 804 and is threadedly connected to the frame 1.

[0050] When adjusting the guide mechanism 8, first loosen the second positioning bolt 803. Since the end of the mounting plate 801 has a through hole 804 (for the second positioning bolt 803 to pass through), the mounting plate 801 can rotate around the axis of the second positioning bolt 803, thereby driving the L-shaped guide plate 802 fixed inside the mounting plate 801 to adjust its angle. When the guiding direction of the L-shaped guide plate 802 matches the feeding requirements of the subsequent process, tighten the second positioning bolt 803 to make the mounting plate 801 fit tightly against the outer side of the end of the frame 1, and the position of the L-shaped guide plate 802 is locked. When the lens module moves to the guide mechanism 8 with the conveyor belt 2, the L-shaped guide plate 802 will contact the module from the side or bottom, limiting the offset direction of the module and ensuring that the module enters the subsequent process in the correct posture, while also helping to buffer the slight impact when the module is transferred.

[0051] like Figure 1 As shown, in a preferred embodiment, based on the above method, the inner wall of the corrugated guide plate 4 is further provided with a flexible buffer layer. The flexible buffer layer is made of silicone material to avoid scratch damage when the lens module comes into contact with the inner wall of the corrugated guide plate 4.

[0052] like Figure 1 As shown, in a preferred embodiment, based on the above method, the height of the side guard plate 5 is not less than the thickness of the lens module, and the side of the side guard plate 5 facing the conveyor belt 2 has an arc transition structure to reduce the impact stress when the lens module collides with the side of the side guard plate 5.

[0053] like Figure 3 As shown, in a preferred embodiment, based on the above method, the top of the vertical plate 601 is further provided with two sets of sliding rods 602, and the line connecting the two sets of sliding rods 602 is parallel to the length direction of the frame 1. This ensures that the corrugated guide plate 4 maintains a horizontal posture when moving up and down, avoids the module tilting or shifting due to uneven force on one side, and further improves the stability of the buffering process.

[0054] Example 3

[0055] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0056] Equipment pre-adjustment stage

[0057] Before starting the equipment, first complete the mechanism position calibration according to the specifications of the lens modules currently being produced and the unloading station of the robotic arm:

[0058] Loosen the first positioning bolt 703, push the slider 702 to slide along the slide groove 701, and drive the vertical plate 601, buffer mechanism 6 and corrugated guide plate 4 to move until the top of the corrugated guide plate 4 is aligned with the trajectory of the robotic arm release module; then tighten the first positioning bolt 703 to lock the position of the slider 702 and ensure that the receiving position of the corrugated guide plate 4 is accurate.

[0059] Loosen the second positioning bolt 803 and rotate the mounting plate 801 to adjust the angle of the L-shaped guide plate 802 so that the guiding direction of the L-shaped guide plate 802 is aligned with the feed inlet of the subsequent process (such as the finished product storage box or the inspection station). After the adjustment is completed, tighten the second positioning bolt 803 to fix the position of the mounting plate 801 and the L-shaped guide plate 802 to ensure the accuracy of the subsequent conveying direction of the module.

[0060] Material conveying start-up phase

[0061] Start the drive motor 3. The drive motor 3 drives the conveyor belt 2 on the top of the frame 1 to rotate at a constant speed along the length of the frame 1. The conveyor belt 2 maintains a stable speed to provide continuous power for the subsequent transfer of the module.

[0062] Lens module acceptance and buffering phase

[0063] The robotic arm moves the lens module from the assembly station to above the conveyor belt 2. After releasing the module, it falls under gravity and first contacts the corrugated guide plate 4.

[0064] The flexible silicone buffer layer on the inner wall of the corrugated guide plate 4 prevents the module surface from being scratched, and the side guards 5 on both sides prevent the module from rolling to the side and reduce collision stress; the corrugated structure of the corrugated guide plate 4 guides the module to adjust its posture along the running direction of the conveyor belt 2, and prevents the module from flipping over disorderly.

[0065] The impact of the falling module causes the corrugated guide plate 4 to press downwards, which in turn causes the slide rod 602 to slide down the vertical channel of the vertical plate 601. The spring 603 on the outside of the slide rod 602 is compressed, converting the kinetic energy of the falling module into the elastic potential energy of the spring 603, which quickly offsets the impact. When the impact disappears, the spring 603 elastically returns to its original position, pushing the slide rod 602 to slide upwards, which in turn causes the corrugated guide plate 4 to return to its initial height, preparing for the next module to be received.

[0066] Module transfer and subsequent bootstrapping phase

[0067] After the lens module's posture is adjusted by the corrugated guide plate 4, it will smoothly transition onto the surface of the conveyor belt 2 under its own gravity and the rotation of the conveyor belt 2. The conveyor belt 2 will move the module away from the corrugated guide plate 4. When the module reaches the guiding mechanism 8, the L-shaped guide plate 802 will constrain the module's posture from the side, guiding the module to maintain a straight line and preventing the module from deviating due to minor unevenness on the surface of the conveyor belt 2. Finally, guided by the L-shaped guide plate 802, the module will accurately enter the feeding area of ​​the subsequent process, completing the entire discharge process.

[0068] 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.
