For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0040] Refer to Figure 1 and Figure 2 , a multi-workpiece loader, including a frame 1, the front and rear sides of the frame 1 are open, the front side of the frame 1 is set as the first workpiece feeding end, the rear side is the discharging end, the left and right sides of the frame 1 are respectively provided with a first through port and a second through port, the first through port is the second workpiece feeding end, the second through port is the visual inspection port, a visual inspection area is arranged on the frame 1, the visual inspection area is arranged near the visual inspection port, and a first workpiece carrying fixture and a second workpiece carrying fixture are arranged at the discharging end.

[0041] As Figure 2 shown, a first loading mechanism 2, a second loading mechanism 3, a picking mechanism 5, a rotary mirror fixture 7, a buffer mechanism 4 and a visual inspection component 6 are arranged in the frame 1. The first loading mechanism 2 is arranged at the first workpiece feeding end, and the first loading mechanism 2 is a plurality of linear transmission devices 21 arranged side by side in the left-right direction. A material placing fixture 22 is arranged on each linear transmission device 21.

[0042] As Figure 2 and Figure 3 shown, the second loading mechanism 3 is arranged at the second workpiece feeding end. The second loading mechanism 3 includes a drawer-type slide plate 31. The drawer-type slide plate 31 penetrates through the first through port and is slidably connected to the frame 1. A loading tray 32 is arranged on the drawer-type slide plate 31, and a placing groove for placing the second workpiece is arranged on the loading tray 32. In this embodiment, the first workpiece is a lens barrel and the second workpiece is a lens. The lens is placed vertically in the placing groove on the loading tray 32. A vacuum suction nozzle 33 is arranged on the drawer-type slide plate 31 to firmly adsorb the tray on the drawer-type slide plate 31 to maintain its stability. The vacuum suction nozzle 33 can detect whether there is a loading tray 32 on the drawer-type slide plate 31 and whether the loading tray 32 is placed stably. A plurality of vacuum suction nozzles 33 are arranged at the same height. According to the negative pressure feedback of each vacuum suction nozzle 33, it is judged whether each vacuum suction nozzle 33 sucks the bottom of the loading tray 32. If the negative pressure feedback of some vacuum suction nozzles 33 has a large difference from that of other vacuum suction nozzles 33, it is judged that the loading tray 32 is not placed flat.

[0043] As Figure 2 shown, the buffer mechanism 4 includes a first buffer rack 41 and a second buffer rack 42. Refer to Figure 4 and Figure 5, both the first buffer rack 41 and the second buffer rack 42 include a rack body 43, a rack platform 44 and a plurality of buffer positions. The rack platform 44 is connected to the top of the rack body 43. The plurality of buffer positions in the first buffer rack 41 are arranged on the rack platform 44 along the Y direction (the Y-axis direction is the front-back direction), and the plurality of buffer positions in the second buffer rack 42 are arranged on the rack platform 44 along the X-axis direction (the X-axis direction is the left-right direction). The first buffer rack 41 is arranged between the first loading mechanism 2 and the picking mechanism 5. The rack body 43 of the second buffer rack 42 is arranged on one side of the frame 1 where there is an inspection opening. The rack platform 44 in the second buffer rack 42 is slidably connected to the rack body 43. There is a sliding opening on the inspection area side of the frame 1 for the rack platform 44 of the second buffer rack 42 to slide. The staff can pull out the rack platform 44 of the second buffer rack 42 to conduct spot checks on the lens barrels on the second buffer rack 42.

[0044] As Figure 6 shown, the inspection assembly 6 includes a first inspection table 61 and a second inspection table 62 that are slidably arranged on the frame 1. The first inspection table 61 and the second inspection table 62 are arranged at the inspection opening. Inspection brackets for supporting the inspection tables are arranged below both the first inspection table 61 and the second inspection table 62. The first inspection table 61 and the second inspection table 62 can be pulled out from the frame 1 through the second through opening. A first inspection slot is connected to the first inspection table 61, and a second inspection slot is connected to the second inspection table 62. The first inspection slot is the first inspection loading position, and the second inspection slot is used to place the workpieces that fail the inspection. Pull out the second inspection table 62, take out the unqualified workpieces, perform manual repair on them, and then place the repaired workpieces on the first inspection table 61.

[0045] It should be noted that, as Figure 7 shown, a plurality of detection holes 63 are arranged on both the first inspection table 61 and the second inspection table 62. One detection hole 63 is opposite to one first inspection slot or second inspection slot. Sensors 64 are arranged at the bottoms of the first inspection table 61 and the second inspection table 62. The detection ends of the sensors 64 are opposite to the detection holes 63, and are used to detect whether there are workpieces on the first inspection slot and the second inspection slot.

[0046] Flap pieces are connected to the rack platform 44 of the second buffer rack 42, the first inspection table 61, and the second inspection table 62. The flap pieces are located below the rack platform 44 of the second buffer rack 42, the first inspection table 61, and the second inspection table 62. Photoelectric sensors 64 are connected to the rack body 43 of the second buffer rack 42 and the inspection brackets. Specifically, the photoelectric sensor 64 includes a transmitting end and a receiving end. When the rack platform 44 of the second buffer rack 42, the first inspection table 61, and the second inspection table 62 are pushed to the working positions inside the frame 1, the flap piece moves between the transmitting end and the receiving end, blocking the receiving end from receiving the optical signal from the transmitting end, indicating that the rack platform 44 of the second buffer rack 42, the first inspection table 61, and the second inspection table 62 are in place.

[0047] As Figure 5 shown, limit holes are provided on the platform 44 of the second buffer rack 42, the first visual inspection table 61, and the second visual inspection table 62. The frame 43 of the second buffer rack 42 and the visual inspection support are both connected with a lifting control member 66 and a limit pin shaft 65. The limit pin shaft 65 is connected to the output end of the lifting control member 66, and the limit pin shaft 65 is inserted and matched with the limit hole, so that the platform 44 of the second buffer rack 42, the first visual inspection table 61, and the second visual inspection table 62 are stably in the working position.

[0048] As Figure 2 shown, the first workpiece carrying fixture is also a linear transmission device 21. The first workpiece carrying fixture is arranged between the frame 1 and the next process to realize the transmission of the first workpiece. The second workpiece carrying fixture is a rotary mirror fixture 7. The rotary mirror fixture 7 is used to rotate the vertically placed lens into a horizontal state for the subsequent process to perform the bonding operation on the lens.

[0049] As Figure 8 shown, the picking mechanism 5 includes a mounting base 51, a multi-axis robotic arm 52, a picking mounting plate, a first grasping component 53, and a second grasping component 54. The mounting base 51 is located on the left side of the second feeding mechanism 3, and a plurality of frames 1 are symmetrically arranged on the front and rear sides of the mounting base 51. The picking mounting plate is connected to the mounting base 51 through the multi-axis robotic arm 52. The first grasping component 53 and the second grasping component 54 are both arranged on the picking mounting plate. The multi-axis robotic arm 52 can drive the picking mounting plate to move along the Z-axis direction and move in the XY plane. The multi-axis robotic arm 52 can control the second grasping component 54 to grasp the lens on the loading tray 32.

[0050] As Figure 9 shown, the first grasping component 53 is connected to the picking mounting plate through a compensation block 531. Since the current product is grasped from the fine positioning fixture and placed into the fine positioning fixture, the debugging difficulty of the points is large. The compensation block 531 of Schunk is added to compensate for the displacement in the X and Y directions by ±1.5 mm to realize better handling of the lens barrel. The second grasping component 54 includes a clamping driving member 532 and a clamping plate 533. The clamping driving member 532 is connected to the bottom of the compensation block 531. The clamping driving member 532 has two output ends, and a clamping plate 533 is connected to each output end. The clamping driving member 532 controls the two clamping plates 533 to move in the direction of approaching or separating from each other. In this embodiment, the clamping driving member 532 is a double-acting cylinder, and a clamping plate 533 is connected to each of the two output ends of the double-acting cylinder. Positioning pins 536 are connected to the side walls of the two clamping plates 533 facing each other, and the positioning pins 536 are adapted to the positioning holes on the lens barrel.

[0051] A pressing block 535 is connected to the compensation block 531 through an elastic component 534. The elastic component 534 includes a guide post, a spring and a guide sleeve. The guide post is connected to the bottom of the compensation block 531, the guide sleeve is connected to the top of the pressing block 535, the guide sleeve is sleeved on the guide post, and an avoidance hole for the guide post to avoid is arranged on the pressing block 535. The spring is located in the guide sleeve and sleeved on the guide post. The pressing block 535 is located between two clamping plates 533. When grasping the lens barrel, the lens barrel is conveyed to the front position inside the frame 1. The multi-axis robotic arm 52 controls the first grasping component 53 to move above the lens barrel. The clamping plates 533 are located on both sides of the lens barrel. The multi-axis robotic arm 52 controls the pick-up mounting plate to move towards the lens barrel. The pressing block 535 abuts against the top surface of the lens barrel. The elastic component 534 provides buffering for the pressing block 535. The clamping driving part 532 controls the clamping plates 533 to move towards the lens barrel. The positioning pin 536 is inserted into the positioning hole on the lens barrel to grasp the lens barrel.

[0052] As Figure 10 shown, the second grasping component 54 includes a Z-axis driving part 541 and a flexible clamping jaw 542. In this embodiment, the Z-axis driving part 541 is a slide cylinder. The flexible clamping jaw 542 is connected to the slide cylinder. The slide cylinder controls the flexible clamping jaw 542 to move along the Z-axis direction. The second workpiece is a thin sheet workpiece. The second workpiece is vertically placed in the loading tray 32, making full use of the space of the loading tray 32 and increasing the single-time feeding quantity of the loading tray 32. When the flexible clamping jaw 542 grasps the vertically placed second workpiece, it does not require the guidance of a vision system, thus making it more convenient to grasp and feed the lens. A detecting part 543 is connected to the slide cylinder. The detecting part 543 is used to detect the opening and closing state of the flexible clamping jaw 542 to judge whether the material is clamped to realize the closed loop of picking up the lens. The detecting part 543 can be an optoelectronic sensor 64.

[0053] As Figure 2 shown, the first loading mechanism 2, the buffer mechanism 4, the lens rotating jig 7, and the second loading mechanism 3 are sequentially arranged circumferentially around the picking mechanism 5. Thus, the picking mechanism 5 is surrounded by the first loading mechanism 2, the second loading mechanism 3, the buffer mechanism 4, and the lens rotating jig 7. Therefore, the multi-axis robotic arm 52 in one picking mechanism 5 can cover all the loading moving line ranges of the first workpiece and the second workpiece in the XY plane, thus realizing the loading of two kinds of workpieces at the same time.

[0054] The implementation principle of the present utility model is as follows:

[0055] The lens barrel is conveyed into the frame 1 through the linear transmission device 21 in the first loading mechanism 2. Under the control of the multi-axis robotic arm 52, the first grasping component 53 moves above the lens barrel to grasp the lens barrel.

[0056] Vertically stack the lenses in the loading tray 32, pull out the drawer-type slide plate 31, place multiple trays with stacked lenses on the drawer-type slide plate 31, and then push the drawer-type slide plate 31 back into the frame 1. The baffle moves out from between the emitting end and the receiving end of the photoelectric sensor 64, and the vacuum suction nozzle 33 sucks the tray and holds it on the drawer-type slide plate 31 to ensure the stability of the drawer-type slide plate 31 during movement. The second grasping component 54 grasps and moves the lenses vertically placed on the tray to the rotary mirror fixture 7, and the rotary mirror fixture 7 rotates the lenses from the vertical state to the horizontal state for subsequent lens mounting operations.

[0057] After the lens barrel is removed from the first loading mechanism 2, it can be placed on the first buffer rack 41 between the first loading mechanism 2 and the multi-axis robotic arm 52 or on the second buffer rack 42 in the visual inspection area. The platform 44 on the second buffer rack 42 can be pulled out of the frame 1, so that the staff can conduct spot checks on the lens barrels on the platform 44. The unqualified workpieces are grasped and placed on the second visual inspection table 62. The second visual inspection table 62 is pulled out, and the unqualified workpieces are taken out for manual repair. After repair, the first visual inspection table 61 is pulled out and the repaired workpieces are put back into the frame 1.

[0058] In summary, through the reasonable layout of the first loading mechanism 2, the second loading mechanism 3, and the picking mechanism 5, and by integrating various grasping components on the multi-axis robotic arm 52, the present application realizes the feeding of multiple workpieces using the same feeding machine. By reasonably arranging the buffer area within the frame 1, compared with the independent buffer mechanism 4, this solution can greatly save costs and reduce the impact of downtime of subsequent equipment.
