Description

Technical Field

[0001] The present application relates to the technical field of lens manufacturing, and particularly to a lens feeding mechanism and a lens assembly device. Background Art

[0002] During the manufacturing process of vehicle-mounted lenses, multiple parts need to be separately manufactured and then assembled and matched to integrate a complete vehicle-mounted lens. In actual manufacturing, components such as lens bases, lenses, and lens retaining rings are placed on their respective corresponding trays and moved to corresponding workstations via transfer modules for operation.

[0003] In a patent application named "A Feeding Mechanism for a Locking Machine Tray", it is mainly disclosed that a gantry is used to support the first clamping component and the second clamping component, and a horizontally moving feeding component and a lens barrel storage are arranged below the gantry. The feeding component and the gantry are arranged in a "cross" shape. The feeding component can transport the material to be processed to the first clamping component and the second clamping component for feeding. Although the overall feeding efficiency is relatively high, the overall structure is complex, and the setting of the gantry results in a relatively large floor space. Summary of the Utility Model

[0004] Based on this, it is necessary to provide a lens feeding mechanism that not only simultaneously takes into account the three processes of feeding, material taking, and recycling, improves the operation efficiency, but also improves the space utilization rate, meets the feeding requirements at different heights, and reduces the occupied space on the horizontal plane.

[0005] A lens feeding mechanism includes a frame and a transfer component: the frame is configured with a feeding channel penetrating in the vertical direction, and the frame is provided with working stations, a feeding station, and a recycling station arranged at intervals in a first direction at the feeding channel, and the first direction forms an angle with the vertical direction; the transfer component is arranged below the frame and includes a horizontal transfer module and a lifting module. The lifting module can flow between each station along the feeding channel under the action of the horizontal transfer module.

[0006] It can be understood that setting the transfer component below the frame can, on the one hand, make full use of the space below the frame and improve space utilization rate, and on the other hand, facilitate the installation of other structures above the frame, so that both the upper and lower spaces of the frame are fully utilized. Moreover, due to the setting of the feeding channel on the frame, it is convenient for the support plate in the transfer component below to shuttle vertically in the feeding channel to meet the feeding requirements at different heights. At the same time, combined with the setting of the horizontal transfer module, it is convenient for the support plate to flow between the working station, the loading station and the recycling station, so as to transfer the full-load tray at the loading station to the working station, and the empty tray after taking materials from the working station can be transferred to the recycling station for empty tray recycling. In this way, the combination of loading, taking materials and recycling is realized, and the operation efficiency is improved. Compared with supporting material transfer through a gantry, such a setting in this application can realize the tray conveying of three stations by using the linear movement of the support plate in the horizontal and vertical directions, and the structure is simpler; moreover, such a setting reduces the space occupied by the feeding mechanism on the horizontal plane and has stronger applicability.

[0009] In some embodiments, the loading support component further includes a positioning cartridge, the positioning cartridge is surrounded by a receiving space that penetrates vertically, and each of the support blocks is disposed at a position below the receiving space of the positioning cartridge.

[0010] In some embodiments, the lens feeding mechanism further includes a recycling carrier component disposed at the recycling station; the recycling carrier component includes at least two carrier blocks, each of the carrier blocks is disposed on both sides of the feeding channel along the second direction and is movably connected to the frame for supporting an empty tray.

[0028] Unless otherwise defined, all technical and scientific terms used in the description of this application have the same meaning as commonly understood by those skilled in the technical field to which this application pertains. The terms used in the description of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0029] Please refer to Figures 1 to 3 , an embodiment of this application provides a lens feeding mechanism, including a frame 10 and a transfer component 20. The frame 10 is configured with a feeding channel 101 penetrating in the vertical direction (i.e., the Z-axis direction). The frame 10 is provided with working stations 11, a loading station 12 and a recycling station 13 arranged at intervals in the first direction at the feeding channel 101. Among them, the first direction forms an angle with the vertical direction. The first direction may be the length direction of the feeding channel 101. Taking the X-axis direction as an example, the width direction of the feeding channel 101 may be the Y-axis direction. The transfer component 20 is arranged below the frame 10 and includes a horizontal transfer module 21 and a lifting module 22, which are connected. The lifting module 22 can flow between each station along the feeding channel 101 under the action of the horizontal transfer module 21. The lifting module 22 at least includes a support plate 221, and the support plate 221 can carry the tray 200 to lift vertically to shuttle through the feeding channel 101.

[0030] It can be understood that the transfer component 20 is arranged below the frame 10. On the one hand, the space below the frame 10 is fully utilized, improving the space utilization rate. On the other hand, the assembly of the transfer component 20 does not occupy the space above the frame 10, facilitating the installation of more other structures above the frame 10, and thus making full use of both the upper and lower spaces of the frame 10. Moreover, due to the setting of the feeding channel 101 on the frame 10, it is convenient for the support plate 221 in the transfer component 20 below to shuttle vertically within the feeding channel 101 to meet the feeding requirements at different heights. In this process, combined with the setting of the horizontal transfer module 21, it is convenient for the support plate 221 to carry the tray 200 and flow between the working station 11, the loading station 12, and the recycling station 13. In this way, the fully loaded tray at the loading station 12 can be moved to the working station 11, facilitating the assembly structure at the working station 11 to pick up the lens components for assembly operations. The empty tray from which the components have been removed can be transferred to the recycling station 13 for empty tray recycling.

[0031] Therefore, the lens feeding mechanism provided in this embodiment can take into account the three processes of loading, picking, and recycling simultaneously, improving the operation efficiency. Compared with supporting the material transfer by a gantry, with this setting in this embodiment, by using the linear movement of the support plate 221 in the X-axis direction and the linear movement in the Z-axis direction, the conveying of the tray 200 at the three stations can be achieved, and the structure is simpler. Moreover, with such a setting, the space occupied by the feeding mechanism on the horizontal plane is reduced, especially the space occupied in the Y-axis direction, and the applicability is stronger.

[0032] In some specific embodiments, the horizontal transfer module 21 can adopt a lead screw drive. The lead screw nut is connected with a bearing seat, the lifting module 22 is arranged on the bearing seat, and the lead screw 212 drives the bearing seat to move in the X-axis direction under the action of the driving motor 211, thereby realizing the reciprocating movement of the support plate 221 in the lifting module 22 in the X-axis direction to meet the flow of the tray 200 between the stations.

[0033] Such as Figure 1 and Figure 3As shown, further, the transfer component 20 also includes a transfer seat 23 and a plurality of connecting columns 24, the plurality of connecting columns 24 are arranged at intervals along the circumference of the feeding channel 101, each connecting column 24 is connected between the transfer seat 23 and the frame 10, and the horizontal transfer module 21 is arranged on the transfer seat 23. Specifically, the transfer seat 23 is provided with an avoidance hole 2301 penetrating along the Z-axis direction, the horizontal transfer module 21 is arranged at the avoidance hole 2301, and the driving motor 211 is installed on the side of the transfer seat 23 away from the frame 10. A guide rail 213 is arranged at the edge of the avoidance hole 2301 of the transfer seat 23, and the guide rail 213 is connected to the bearing seat through a slider to guide the movement of the bearing seat in the X-axis direction. The setting of the plurality of connecting columns 24 not only satisfies the assembly of the transfer seat 23 relative to the frame 10, but also promotes sufficient assembly space between the transfer seat 23 and the frame 10, which is convenient for the assembly of the lifting module 22.

[0034] In actual use, a motor mounting seat 26 may be provided on the side of the transfer seat 23 away from the frame 10 to support the drive motor 211. At the same time, four connecting posts 24 are provided, which are respectively provided at the four top corners of the transfer seat 23 to ensure balanced force. Alternatively, three, five, etc. connecting posts 24 may be provided.

[0035] like Figure 1 As shown, further, the lifting module 22 also includes a lifting cylinder 222 and a connecting rod 223. The piston rod of the lifting cylinder 222 is connected to the support plate 221, and is used to drive the support plate 221 to rise and fall along the Z-axis direction. The connecting rod 223 is connected between the bearing seat and the support plate 221, and is used to guide the lifting and lowering of the support plate 221. The connecting rod 223 can be connected to the bearing seat using a linear bearing. At least two connecting rods 223 are provided, and are arranged on both sides of the piston rod in the radial direction to ensure balanced force.

[0036] See also Figure 1 and Figure 3 Optionally, the lens feeding mechanism further includes a second detection component 60 disposed on the transfer component 20, which is used to detect the position of the support plate 221 at each station (i.e., the aforementioned working station 11, the loading station 12, and the recycling station 13). Specifically, the second detection component 60 includes a trigger plate 61 and a second sensor 62. The trigger plate 61 is mounted on the support plate 221. The second sensor 62 is mounted on the frame 10 and is provided in three numbers, which are respectively disposed at each of the aforementioned stations. The trigger plate 61 moves along the X-axis direction with the support plate 221. When the trigger plate 61 moves into the sensing slot of the second sensor 62, the second sensor 62 can be triggered to send a sensing signal to determine the station where the support plate 221 is located.

[0037] Meanwhile, the lifting cylinder 222 in the lifting module 22 is also provided with a sensor for detecting the extended position of the piston rod, and further determining the position of the support plate 221 in the vertical direction. The sensor on the lifting cylinder 222 is a mature existing technology and not an improvement point of this application, so it will not be elaborated here.

[0038] As Figure 3 shown, as another alternative, the support plate 221 is provided with a plurality of positioning columns 224 arranged at intervals. It can be understood that since the support plate 221 is used to support and carry the tray 200, the positioning columns 224 can be in positioning cooperation with the tray 200 to improve the support stability of the support plate 221 for the tray 200. Specifically, four positioning columns 224 can be provided and arranged at the four top corners of the support plate 221 respectively. Or, the support plate 221 is provided with two, three, six or the like positioning columns 224.

[0039] It should be noted that the support plate 221 can also be convexly provided with a plurality of support protrusions arranged at intervals, and the support protrusions are used to support the tray 200, reducing the contact area with the tray 200 and reducing wear. Moreover, the support plate 221 can also be provided with through holes. On the one hand, it realizes the lightweight design of the support plate 221, reduces the load of the lifting cylinder 222 and the horizontal transfer module 21, and on the other hand, it can avoid some structures on the tray 200 and improve the protection performance.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 4 , exemplarily, the lens feeding mechanism further includes a loading support member 30 provided at the loading station 12. The loading support member 30 includes at least two support blocks 31, and the at least two support blocks 31 are respectively arranged on both sides of the feeding channel 101 along the second direction. Each support block 31 is movably connected to the frame 10 and is used to support the full-load tray. Among them, the first direction, the second direction and the vertical direction are arranged at an angle to each other. Taking the second direction as the Y-axis direction as an example. The two support blocks 31 are respectively arranged on both sides of the feeding channel 101 along the Y-axis direction. Since each support block 31 is movable relative to the frame 10, the support state of each support block 31 can be adjusted. When the support block 31 moves to be located in the feeding channel 101, it can support the bottom of the full-load tray. When the support block 31 moves out of the feeding channel 101, the support for the full-load tray is released. At this time, the full-load tray is supported by the support plate 221 to realize material taking.

[0041] In some embodiments, two support blocks 31 can be provided, which are opposite and spaced apart along the Y-axis direction. Or, three support blocks 31 can be provided, with two support blocks 31 spaced apart along the X-axis direction on one side of the feeding channel 101 along the Y-axis direction and one support block 31 on the other side. Or, four support blocks 31 can be provided, with two as a group. Only examples are given here.

[0042] Further, the loading support member 30 further includes a power source 32. Each support block 31 is connected to a power source 32 and moves toward each other and away from each other along the Y-axis under the action of the corresponding power source 32. In this way, when two support blocks 31 are required to cooperate to support a fully loaded tray, the two support blocks 31 move toward each other under the action of their respective power sources 32 to approach each other for supporting the bottom of the fully loaded tray. When the transfer member 20 needs to pick up the material, the support plate 221 rises under the action of the lifting cylinder 222 to support the bottom of the fully loaded tray. After the support plate 221 is stably supported, the two support blocks 31 move away from each other under the action of their respective power sources 32 to move out of the feeding channel 101 to release the support for the fully loaded tray and avoid interfering with the descent of the fully loaded tray.

[0043] In some specific embodiments, each support block 31 reciprocates linearly along the Y-axis under the action of its respective power source 32 to support and release the support for the fully loaded tray. At this time, the power source 32 is a cylinder or an electric push rod, etc. The setting of linear reciprocating movement has better support stability because it only has a movement trend along the Y-axis. Alternatively, each support block 31 swings around the X-axis under the action of its respective power source 32 to support and release the support for the fully loaded tray. At this time, the power source 32 is a motor. Only examples are given here, as long as it can realize the support and release of the support for the fully loaded tray by the support block 31.

[0044] During actual use, a plurality of trays 200 stacked vertically are arranged at the loading station 12, and there is a gap between any two adjacent trays 200. Therefore, when the previous fully loaded tray is supported on the support plate 221, the lifting cylinder 222 drives the support plate 221 to move down a small distance, causing the support block 31 to be located at the previous gap, and the two support blocks 31 can move toward each other again to extend into the corresponding gap to support the next fully loaded tray.

[0045] Such as Figure 1 and Figure 2As shown, further, the loading support member 30 further includes a positioning material box 33, and a vertically penetrating accommodating space 3301 is defined around the positioning material box 33. Each support block 31 is disposed at a position of the positioning material box 33 below the accommodating space 3301. That is to say, the positioning material box 33 is provided to protect a plurality of fully loaded trays, preventing the trays 200 from shaking, tilting, shifting, etc. due to excessive number. The positioning material box 33 includes two half-box bodies arranged opposite to and spaced apart from each other in the Y-axis direction. Each half-box body is U-shaped, and the bottom of each half-box body can be supported on the frame 10 through at least two support columns 34. The two U-shaped half-box bodies together define the accommodating space 3301. The corresponding power sources 32 of the two support plates 221 described above can be respectively installed at the bottom of one half-box body to achieve support in the Y-axis direction.

[0046] As Figure 1 shown, in actual use, the lens feeding mechanism further includes a first detection component 50. The first detection component 50 is disposed at the loading station 12 and is used to detect whether there is material at the loading station 12. That is to say, through the detection of the first detection component 50 on the fully loaded tray, it is convenient to control the transfer component 20 to start for loading. Among them, the first detection component 50 includes a support frame 51 and a first sensor 52 connected to the support frame 51. The support frame 51 is installed on the frame 10. When the first sensor 52 detects that there is no material at the loading station 12, an alarm can be used for warning, and at this time, the transfer component 20 also stops conveying.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 5 , as another exemplary one, the lens feeding mechanism further includes a recycling and carrying component 40 disposed at the recycling station 13. The recycling and carrying component 40 includes at least two carrying blocks 41. The at least two carrying blocks 41 are respectively disposed on both sides of the second direction (i.e., the Y-axis direction) of the feeding channel 101. Each carrying block 41 is movably connected to the frame 10 and is used to support the empty tray. It can be understood that since each carrying block 41 is movable relative to the frame 10, the supporting states of the carrying blocks 41 can be adjusted. The support plate 221 transfers the empty tray to the recycling station 13 and rises under the action of the lifting cylinder 222. At this time, the carrying block 41 moves out of the feeding channel 101 to avoid interfering with the rising of the empty tray. When the empty tray moves into place, the carrying block 41 moves to be located within the feeding channel 101 to support the bottom of the empty tray, realizing the recycling of the empty tray.

[0048] In some embodiments, four bearing blocks 41 may be provided, with two in a group and arranged along the Y-axis direction. For example, they may be exactly located at the four top corners of the empty tray, which not only improves the support effect but also has a regular distribution and reduces interference. Alternatively, two bearing blocks 41, three bearing blocks 41, or even five bearing blocks 41 may be provided, as long as the support effect is satisfied. Only examples are given here.

[0049] As Figure 2 and Figure 5 shown, further, the recycling and bearing component 40 further includes a base 42 and a restoring member (not shown in the figure). Each bearing block 41 is movably connected to a base 42, and a restoring member is connected between the corresponding bearing block 41 and the base 42. The base 42 is provided on the frame 10 to enable the frame 10 to support the bearing block 41. Along the Y-axis direction, each bearing block 41 can move away from each other under the pressing action of the empty tray, and each restoring member is used to apply a force to the corresponding bearing block 41 to move closer to each other.

[0050] That is to say, when the lifting cylinder 222 drives the support plate 221 to move upward at the recycling station 13, the empty tray abuts against the bearing blocks 41 on both sides in the Y-axis direction. As the empty tray rises, it can press the bearing block 41 to move along the Y-axis direction away from the tray 200. When the empty tray moves above the bearing block 41, the bearing block 41 loses the pressing force of the empty tray and moves along the Y-axis direction toward the side close to the empty tray under the action of the restoring member to support the bottom of the empty tray. Among them, the restoring member can be a spring.

[0051] As Figure 5 shown, in actual use, along the second direction, guiding inclined surfaces 411 are provided on the opposite sides of each bearing block 41, and the distance between the two guiding inclined surfaces 411 along the second direction increases gradually from top to bottom. Such a setting facilitates the empty tray to press the bearing block 41 along the guiding inclined surface 411 and move more smoothly above the bearing block 41.

[0052] In some specific embodiments, on one side of each base 42 facing the bearing block 41 along the Y-axis direction, a concave cavity 4201 is formed to facilitate accommodating the bearing block 41. The lower part of the bearing block 41 is accommodated in the concave cavity 4201 and is rotatably connected to the base 42 through a rotating shaft. The restoring member is sleeved on the rotating shaft, with one end connected to the base 42 and the other end connected to the bearing block 41. Or, the bearing block 41 is slidably connected to the base 42, and the restoring member is connected between the base 42 and the bearing block 41. When the bearing block 41 supports the empty tray, part of it is inside the concave cavity 4201 and part of it is outside the concave cavity 4201.

[0053] Furthermore, the recycling and supporting component 40 further includes at least two assembling seats 44. Each assembling seat 44 is fixedly arranged on the frame 10 and is constructed with an assembling cavity 4401, and the base 42 is installed in the assembling cavity 4401. By means of the arrangement of the assembling seats 44, the supporting stability of each supporting block 41 relative to the frame 10 is improved, and thus the supporting stability is further improved.

[0054] During actual use, no-material detection can be provided at both the recycling station 13 and the working station 11.

[0055] It should be added that the recycling and supporting component 40 can also adopt the same structure as the feeding and supporting component 30. At this time, only need to drive each supporting block 31 to move away from each other when the empty tray rises, and after rising above the supporting block 31, drive each supporting block 31 to move closer to each other. Or, the aforementioned supporting block 31 and the supporting block 41 are used in cooperation, as long as the rising and avoidance and support of the empty tray are realized.

[0056] Another embodiment of the present application provides a lens assembling device, including the above-mentioned lens feeding mechanism. The lens assembling device further includes a handling mechanism and a lens assembling mechanism, both of which are arranged on the upper surface of the frame 10. The handling mechanism can pick up the components transferred to the working station 11 and transport them to the lens assembling mechanism for assembly.

[0057] As Figures 1 to 5 shown, in summary, the specific operation can be as follows:

[0058] The staff can place the lens components in the tray 200 and place the full tray on the loading station 12 to support on multiple support blocks 31. The first sensor 52 in the first detection component 50 detects that the loading station 12 is in the state of having materials, and transmits the detection signal to the control system of the lens assembly device, and controls the transfer component 20 to start via the control system. The support plate 221 moves to the loading station 12 under the action of the horizontal transfer module 21, and then the lifting cylinder 222 drives the support plate 221 to rise to support the bottom of the bottommost full tray. After stable support, each power source 32 drives the corresponding support block 31 to move away from each other along the Y-axis direction to move out of the feeding channel 101. The lifting cylinder 222 drives the support plate 221 to drive the full tray to descend a certain distance, causing the support block 31 to align with the previous gap, and then moving closer to each other along the Y-axis direction under the action of the power source 32 to support the bottom of the second-to-last full tray. Then, the lifting cylinder 222 drives the support plate 221 to continue to move down. After moving in place, the support plate 221 carrying the full tray is transferred to the working station 11 via the horizontal transfer module 21 and rises to the picking height of the aforementioned handling mechanism under the action of the lifting cylinder 222. After the handling mechanism picks up the materials, the lifting cylinder 222 drives the support plate 221 to move down, and the support plate 221 carrying the empty tray is transferred to the recycling station 13 via the horizontal transfer module 21. Then, the lifting cylinder 222 is started again to drive the support plate 221 to move up until the empty tray rises above the bearing block 41. At this time, the bearing block 41 moves closer to each other under the action of the restoring member to support the empty tray, and the support plate 221 can enter the next material picking and feeding cycle under the action of the lifting cylinder 222 and the horizontal transfer module 21.
