[0034] Please see Figures 1 to 5 This embodiment provides a material picking device, which includes a picking mechanism 1 and a conveying mechanism 2. The picking mechanism 1 includes a mounting frame 11 and three picking modules 12, all of which are mounted on the mounting frame 11.

[0035] Of course, in other alternative embodiments, two or more pickup modules 12 may also be installed on the mounting bracket 11, and this embodiment does not impose specific limitations on this.

[0036] The conveying mechanism 2 includes a drive member 21, a first plate 22, a second plate 23, a third plate 24, and a cam follower 25. The first plate 22 is mounted on the movable end 211 of the drive member 21. The cam follower 25 is rotatably connected to the mounting bracket 11 and is drively connected to the first plate 22. The cam follower 25 can rotate with the first plate 22 around a rotation axis extending in a first direction. It can be understood that the rotation axis is the axis of the movable end 211 of the drive member 21. The mounting bracket 11 is slidably connected to the second plate 23 in a second direction, and the second plate 23 is slidably connected to the third plate 24 in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. Moreover, the third plate 24 is provided with a guide groove 241, which is arranged around the outer periphery of the rotation axis. The cam follower 25 is slidably mounted in the guide groove 241.

[0037] Therefore, when the drive member 21 drives the first plate 22 and causes the cam follower 25 to rotate together around the rotation axis extending in the first direction, the cam follower 25 slides along the guide groove 241. As the cam follower 25 rotates, the mounting bracket 11 slides relative to the second plate 23 in the second direction, and the second plate 23 slides relative to the third plate 24 in the third direction. Thus, the picking module 12 provided on the mounting bracket 11 can move in the second direction and the third direction, thereby completing the material picking and placing operation.

[0038] It is understood that the driving component 21 can be selected as a stepper motor or servo motor or other driving structure, and this embodiment does not impose specific restrictions on it.

[0039] Specifically, the picking module 12 can first pick up materials from the loading station. Then, the driving component 21 drives the first plate 22 and drives the cam follower 25 to rotate together around the rotation axis extending in the first direction. During this process, the picking module 12 moves away from the loading station in the second direction and moves from the side close to the loading station to the side close to the unloading station in the third direction. Moreover, after approaching the unloading station, the picking module 12 approaches the unloading station in the second direction, thereby placing the material at the designated unloading station.

[0040] Taking the second direction as the vertical direction and the first and third directions as the horizontal direction as an example, when the driving component 21 drives the first plate 22 and causes the cam follower 25 to rotate together around the rotation axis extending along the first direction, the mounting frame 11 can drive the picking module 12 to move in the vertical and horizontal directions. Specifically, the picking module 12 rises vertically and moves away from the loading station, and moves horizontally from the side near the loading station to the side near the unloading station. After approaching the unloading station, the picking module 12 descends vertically and approaches the unloading station, thereby placing the material at the designated unloading station. Thus, the picking module 12 completes the process of picking up the material from the loading station and placing the material at the designated unloading station.

[0041] Afterwards, the drive unit 21 reverses, and the picking module 12 returns to the loading station to perform the next material picking and placing operation.

[0042] Since the mounting frame 11 is equipped with three picking modules 12, the material picking device can pick up three materials at a time, thereby completing the picking and placing of three materials in each work cycle, which can improve work efficiency.

[0043] Based on the above, the material picking device in this embodiment only requires one drive component 21. Therefore, this embodiment simplifies the structure of the material picking device and reduces its manufacturing cost. Moreover, the material picking device can process more than two materials in a single working cycle, thus achieving high working efficiency.

[0044] Furthermore, it is worth noting that in this embodiment, the three pickup modules 12 are arranged at intervals along the first direction. Moreover, the three pickup modules 12 are used to pick up materials in different ways. For example, in this embodiment, the three pickup modules 12 use clamping, magnetic attraction, and pneumatic suction methods to pick up materials, respectively. Specifically, taking the three pickup modules 12 as a first pickup module 12, a second pickup module 12, and a third pickup module 12 as examples, the first pickup module 12 includes a pneumatic gripper 121, the second pickup module 12 includes a magnetic suction head 122, and the third pickup module 12 includes a suction nozzle 123. The first pickup module 12, the second pickup module 12, and the third pickup module 12 can be respectively adapted to pick up different types of materials. Therefore, this embodiment is compatible with picking up and placing different types of materials.

[0045] That is, based on the mounting frame 11, two or more picking modules 12 are installed, so that the type of each picking module 12 can be arranged adaptively according to the needs, thereby enabling the picking and placing of different types of materials.

[0046] Of course, in other alternative embodiments, all picking modules 12 may also be arranged of the same type, so that the material picking device can pick up and place two or more materials of the same type at one time. This embodiment does not impose specific limitations on this.

[0047] Furthermore, in this embodiment, the guide groove 241 includes a first groove 2411, a second groove 2412, and a third groove 2413. The first groove 2411 and the second groove 2412 are located on both sides of the rotation axis along a third direction and both extend along a second direction. The third groove 2413 connects between the first groove 2411 and the second groove 2412. Therefore, this embodiment can optimize the movement trajectory of the picking module 12. Specifically, the picking module 12 first moves away from the loading station along the second direction, and then moves towards the unloading station along the third direction. After the picking module 12 moves to face the unloading station, it then approaches the unloading station along the second direction, thereby placing the material at the unloading station. During this process, the movement trajectory of the picking module 12 is more reasonable, effectively reducing unnecessary movement distance and further improving work efficiency.

[0048] Furthermore, the third groove 2413 includes a first groove segment 24131, a second groove segment 24132, and a third groove segment 24133. The first groove segment 24131 extends in a third direction, the second groove segment 24132 is arc-shaped and connects the first groove segment 24131 and the first groove 2411, and the third groove segment 24133 is arc-shaped and connects the first groove segment 24131 and the second groove 2412. Thus, this embodiment can further optimize the movement trajectory of the picking module 12.

[0049] Specifically, the length of the first groove segment 24131 is set according to the distance between the loading station and the unloading station. Initially, the cam follower 25 drives the mounting frame 11 to move only along the second direction, so that the picking module 12 moves away from the loading station along the second direction. Then, the cam follower 25 transitions through the second groove segment 24132, and then drives the mounting frame 11 to move only along the third direction towards the side of the unloading station. When the picking module 12 approaches the unloading station, the cam follower 25 transitions through the third groove segment 24133, and then the cam follower 25 drives the mounting frame 11 to move only along the second direction, so that the picking module 12 approaches the unloading station along the second direction.

[0050] Based on this, this embodiment can further reduce unnecessary travel distances, thereby further improving work efficiency.

[0051] Furthermore, based on the above, the first plate 22 is provided with a transmission groove 221, which extends radially along the movable end 211 of the drive member 21. The first plate 22 is clamped to the outer periphery of the cam follower 25 through the transmission groove 221. Thus, the cam follower 25 can move within the transmission groove 221 to adaptively adjust the distance between the cam follower 25 and the movable end 211 of the drive member 21 according to the shape of the guide groove 241. This allows the cam follower 25 to slide smoothly along the guide groove 241, thereby enabling the mounting bracket 11 to smoothly and steadily drive the pickup module 12 to move along a preset trajectory.

[0052] In addition, the material picking device also includes a first slotted photoelectric switch 31 and a second slotted photoelectric switch 32. A light-shielding plate 111 is provided on the mounting bracket 11. The light-shielding plate 111 can be inserted into the first slotted photoelectric switch 31 when the cam follower 25 is located in the first slot 2411, and can be inserted into the second slotted photoelectric switch 32 when the cam follower 25 is located in the second slot 2412. Thus, when the cam follower 25 slides in the guide groove 241, the material picking device can detect the current position of the picking module 12 through the cooperation of the light-shielding plate 111 with the first slotted photoelectric switch 31 and the second slotted photoelectric switch 32, thereby ensuring that the material picking device can accurately place the material at the designated unloading station.

[0053] Specifically, initially, the light-shielding plate 111 is inserted into the first slotted photoelectric switch 31. As the cam follower 25 drives the mounting bracket 11 to move along the second direction, so that the pickup module 12 moves away from the loading station along the second direction, the light-shielding plate 111 is removed from the first slotted photoelectric switch 31. After the cam follower 25 passes through the third slot section 24133 and drives the mounting bracket 11 to move along the second direction, so that the pickup module 12 approaches the unloading station along the second direction, the light-shielding plate 111 can be inserted into the second slotted photoelectric switch 32.

[0054] It is understandable that when the drive component 21 reverses, the movement process of the mounting bracket 11 and the light shield 111 is the opposite of that described above, and this embodiment will not elaborate on this.

[0055] Furthermore, based on the above description, in this embodiment, the mounting frame 11 includes a frame 112 and a first slide rail 113. All pickup modules 12 are mounted on the frame 112. The first slide rail 113 is fixedly connected to the frame 112 and extends along the second direction. The second plate 23 is fixedly connected to a first slider 231, which is slidably connected to the first slide rail 113. This allows the mounting frame 11 to maintain a stable sliding state when it slides relative to the second plate 23 along the second direction, thereby ensuring the smoothness of the pickup module 12 moving along the second direction.

[0056] Furthermore, the second plate 23 is also fixedly connected to the second slider 232, and the third plate 24 is equipped with the second slide rail 242. The second slide rail 242 extends along the third direction, and the second slider 232 is slidably connected to the second slide rail 242. This allows the second plate 23 to maintain a stable sliding state when it slides relative to the third plate 24 along the third direction, thereby ensuring the smoothness of the movement of the picking module 12 along the third direction.

[0057] Furthermore, in this embodiment, two first slide rails 113 are fixedly connected to the frame 112. The two first slide rails 113 are arranged at intervals along a third direction. It is worth noting that in this embodiment, the cam follower 25 is rotatably connected to one of the first slide rails 113. The third plate 24 is equipped with two second slide rails 242, which are arranged at intervals along a second direction, thereby making the structure of the entire material picking device more stable and the sliding connection smoother.

[0058] Of course, in other alternative embodiments, the frame 112 may also be fixedly connected with three or more first slide rails 113, which are arranged at intervals along a third direction. Correspondingly, the third plate 24 may also be equipped with three or more second slide rails 242, which are arranged at intervals along a second direction. This embodiment does not impose specific limitations on this.

[0059] Any first slide rail 113 intersects with all second slide rails 242, and a first slider 231 and a second slider 232 are respectively provided at the intersection of any first slide rail 113 and any second slide rail 242, thereby ensuring the smooth movement of the picking module 12.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
