[0025] like Figures 1 to 9 As shown, this application provides a conveying and positioning mechanism, including a support frame 1, the support frame 1 being provided with: Conveying assembly 2 includes a conveyor belt 200 and a first driving device. The support frame 1 is provided with a baffle plate 100. The first driving device drives the conveyor belt 200 to move the material 6 to the baffle plate 100. The lifting assembly 3 includes a second driving device and a positioning pallet 205 connected to the second driving device. The positioning pallet 205 is located between two conveyor belts 200. The second driving device drives the positioning pallet 205 to move vertically so that the positioning pallet 205 can receive the material 6 and drive the material 6 to leave the conveyor belt 200. X-direction positioning component 4, which includes a third drive device and a centering gripper 400 connected to the third drive device. The centering gripper 400 is located on both sides of the positioning tray 205. The third drive device drives the centering gripper 400 to move in order to grip or release the material 6 located on the positioning tray 205. Y-direction positioning component 5 includes a fourth drive device and a side push plate 500 connected to the fourth drive device. The side push plate 500 is coaxially arranged with the positioning tray 205. The fourth drive device drives the side push plate 500 to move so as to push the material 6 located on the positioning tray 205 to abut against the blocking plate 100.

[0026] This solution integrates the conveying assembly 2, lifting assembly 3, X-direction positioning assembly 4, and Y-direction positioning assembly 5 into the support frame 1, improving the overall structural compactness of the conveying and positioning mechanism. This allows it to adapt to the conveying and positioning of material 6 within a small space, increasing space utilization. The conveying assembly 2, via a first drive device, transports material 6 to the corresponding position. The lifting assembly 3 drives the positioning pallet 205 to move vertically until it lifts material 6, thus detaching the material from the conveyor belt 200 for easy subsequent removal. In this solution, the positioning pallet 205 is positioned between two conveyor belts 200. The two conveyor belts transport material 6, balancing the force on the material 6 while reserving space for the positioning pallet 205, further enhancing structural compactness. In this solution, centering grippers 400 are further provided on both sides of the positioning pallet 205 to center and position the material 6 located on the positioning pallet 205 in the X direction. The side push plate 500 in the Y direction positioning component 5 pushes the material 6 from one side of the positioning pallet 205, so that the material 6 comes into contact with the blocking plate 100. This avoids the material 6 receiving the reaction force of the blocking plate 100 during conveying and thus avoids reverse displacement caused by the reaction force of the blocking plate 100. This achieves accurate positioning of the material 6 and facilitates subsequent accurate picking or adsorption of the material 6.

[0027] Furthermore, the conveying component 2, lifting component 3, X-direction positioning component 4, and Y-direction positioning component 5 in this application scheme, through reasonable division of labor and collaborative cooperation, realize the step-by-step processing of material 6 in the entire conveying and positioning process. In a small working space, it can achieve both functional division and collaborative achievement of the final accurate and rapid positioning effect. Moreover, the length and width of the conveyor belt 200, the moving distance of the lifting component 3, the clamping range of the centering gripper 400, and the pushing distance of the side pusher 500 can all be adaptively adjusted according to the actual production scenario requirements, and can meet the conveying and positioning of materials 6 of different specifications.

[0028] In this solution, the contact surface between the baffle plate 100 and the material 6 is made of flexible material to avoid collision damage to the material 6.

[0029] In one embodiment, such as Figure 1 , Figure 2 As shown, the support frame 1 includes an upper connecting plate 101 and a lower connecting plate 102 arranged opposite to each other. An accommodating area 103 is provided between the upper connecting plate 101 and the lower connecting plate 102. The conveying component 2, the lifting component 3, the X-direction positioning component 4, and the Y-direction positioning component 5 are at least partially located in the accommodating area 103.

[0030] This solution effectively improves the compactness and space utilization of the overall structure by setting an accommodating area 103 between the upper connecting plate 101 and the lower connecting plate 102 and integrating at least part of each functional component into this area. At the same time, it facilitates the centralized installation and maintenance of each component, enhances the overall rigidity and stability of the mechanism, and the setting of the upper connecting plate 101 and the lower connecting plate 102 is conducive to the balance and stability of the overall structure, and defines the direction and space for the overall layout of the conveying and positioning mechanism.

[0031] In one embodiment, such as Figures 1 to 3 As shown, the first drive device includes a first motor 201, a coupling 202 connected to the output end of the first motor 201, a drive shaft 203 connected to the coupling 202, and a driven shaft 204 parallel to the drive shaft 203. The two ends of the conveyor belt 200 are respectively sleeved on the drive shaft 203 and the driven shaft 204. The accommodating area 103 is provided with a motor positioning seat 206 connected to the upper connecting plate 101 and the lower connecting plate 102 respectively. The first motor 201 is fixed to the motor positioning seat 206.

[0032] This design uses a coupling 202 to connect the first motor 201 and the drive shaft 203, ensuring stable and reliable transmission. The conveyor belt 200 is fitted between the drive shaft 203 and the driven shaft 204, featuring a simple structure and easy tension adjustment. The first motor 201 is fixed to the receiving area 103 via a motor positioning seat 206, ensuring stable installation, low vibration, and improved conveying accuracy and lifespan. Furthermore, in this design, the drive shaft 203 and the driven shaft 204 are driven by the same first motor 201, guaranteeing the synchronous rotation of the drive shaft 203 and the driven shaft 204. This design also includes two conveyor belts 200, with each belt's ends connected to both the drive shaft 203 and the driven shaft 204, further ensuring the mechanism's conveying synchronicity and stability. The conveyor belt 200 conveys materials 6 within the receiving area 103, confining the material conveying process between the upper connecting plate 101 and the lower connecting plate 102. Other structures are assembled closer to the receiving area 103, improving the overall structural compactness, reducing the transmission distance, and increasing the working efficiency of the mechanism.

[0033] Furthermore, the lower connecting plate 102 is provided with bearing plates 104 at both ends, and each bearing plate 104 is provided with a limiting hole 108 corresponding to the drive shaft 203 or the driven shaft 204; the top of the bearing plate 104 is provided with a guide hole 105, and the upper connecting plate 101 is provided with an oblong hole 106 that is aligned with the guide hole 105.

[0034] This design uses limiting holes 108 on the bearing plate 104 to limit the movement of the drive shaft 203 and driven shaft 204, ensuring shaft alignment and smooth transmission. The upper connecting plate 101 has oblong holes 106 that mate with guide holes 105, facilitating adjustment of the height and level of the conveying assembly 2 to accommodate materials 6 of different specifications, thus improving the mechanism's adaptability and installation flexibility. Furthermore, in this design, the bearing plate 104 is connected at both ends to the upper connecting plate 101 and the lower connecting plate 102, which helps strengthen the structural strength of the support frame 1, improves the overall stability of the mechanism, ensures smooth conveying, increases the utilization rate of the bearing plate 104, and reduces the need for reinforcing plates.

[0035] In one embodiment, such as Figure 1 , Figure 4 As shown, the positioning pallet 205 is equipped with a material monitoring sensor 207. The second driving device includes a driving cylinder 300. The side wall of the driving cylinder 300 is provided with a mounting plate 301 that is fixedly connected to the lower connecting plate 102. The bottom of the driving cylinder 300 is provided with a cylinder connecting plate 302. The lifting assembly 3 also includes a vertical plate 303 connected to the bottom plate 304 of the positioning pallet 205, and a bottom plate 304 located at the bottom of the vertical plate 303 and fixedly connected to the vertical plate 303. The bottom plate 304 is fixedly connected to the cylinder connecting plate 302.

[0036] This solution uses a material monitoring sensor 207 installed on the positioning pallet 205 to detect the status of the material 6 in real time, thereby improving the accuracy and response speed of the positioning control. The drive cylinder 300 is connected to the vertical plate 303 and the base plate 304 through the mounting plate 301, so that the drive cylinder 300 can drive the positioning pallet 205 to move. This makes the overall structure stable, the transmission direct, and ensures that the pallet can be raised and lowered smoothly and the positioning is accurate.

[0037] Furthermore, such as Figure 2 As shown, the lower connecting plate 102 is provided with a clearance opening 107, and the drive cylinder 300 drives the positioning support plate 205 to move vertically along the clearance opening 107 through the upright plate 303.

[0038] This solution provides a smooth vertical movement space for the positioning tray 205 and the lifting assembly 3 by setting an avoidance opening 107 in the lower connecting plate 102, avoiding structural interference and ensuring reliable lifting action and high repeatability positioning accuracy.

[0039] In one embodiment, such as Figures 5 to 7As shown, the third drive device includes a second motor 401, the output end of the second motor 401 is provided with a gear 402, the X-direction positioning component 4 includes a rack 403 that meshes with the gear 402, the X-direction positioning component 4 also includes a mounting base 404 located between the second motor 401 and the centering gripper 400, the rack 403 is fixed to the mounting base 404, the mounting base 404 is provided with a gripper connecting block 405, the gripper connecting block 405 connects the centering gripper 400 and the rack 403 respectively; The third drive device also includes a guide rail 406 parallel to the rack 403, and a slider 407 at the bottom of the gripper connecting block 405, which is slidably connected to the guide rail 406.

[0040] This solution converts the rotational motion of the second motor 401 into the linear motion of the centering gripper 400 through the meshing of gear 402 and rack 403, enabling the horizontal movement of the centering gripper 400. This results in high transmission accuracy and fast response, which helps improve the stability of the centering process and the centering clamping efficiency. At the same time, guide rails 406 and sliders 407 are provided to guide the movement of the centering gripper 400 linearly, avoiding deviation from the movement path. This helps ensure smooth movement and accurate centering of the centering gripper 400, and enhances the repeatability and reliability of X-direction positioning.

[0041] It should be noted that in this solution, racks 403 are provided on both sides of the gear 402, and centering jaws 400 are distributed on both sides. Each rack 403 is provided with a matching jaw connecting block 405, and the two jaw connecting blocks 405 are provided with a clearance space to avoid the guide rail 406. The slider 407 is set in the clearance space and connects the guide rail 406 and the jaw connecting block 405 respectively, so as to drive the centering jaw 400 to move.

[0042] Furthermore, the bottom of the mounting base 404 is provided with a side plate 408 parallel to the vertical plate 303. The side plate 408 is fixed to the base plate 304. The upper connecting plate 101 is provided with a limiting groove 109 adapted to the centering gripper 400. The drive cylinder 300 drives the centering gripper 400 located in the mounting base 404 to move vertically along the limiting groove 109 through the side plate 408. The side plate 408 surrounds to form the mounting part 409. The second motor 401 is located in the mounting part 409.

[0043] This design uses the side plate 408 to fix the mounting base 404 to the base plate 304, which provides good structural rigidity and improves the overall structural strength and stability. The upper connecting plate 101 is equipped with a limiting groove 109 as a guide to ensure that the centering gripper 400 does not deviate during the lifting process. The second motor 401 is located inside the mounting part 409, which allows for isolation and protection of the second motor 401 through the upright plate 303 and the side plate 408. This provides good protection and makes full use of space, resulting in a compact layout and improving the overall motion stability.

[0044] It should be noted that the side plate 408 is located inside the vertical plate 303, and the centering gripper 400 is set outside the conveyor belt 200 to avoid affecting the transportation of material 6.

[0045] In one embodiment, such as Figure 1 , Figure 8 , Figure 9 As shown, the Y-direction positioning component 5 includes a connecting seat 502, and the fourth driving device includes a lead screw motor 501 located at the bottom of the connecting seat 502. The lead screw end of the lead screw motor 501 is provided with a thread 503 to be fixedly connected to the side wall of the connecting seat 502. The side push plate 500 is fixedly connected to the top surface of the connecting seat 502. The lead screw motor 501 drives the side push plate 500 to move through the connecting seat 502.

[0046] This solution uses a lead screw motor 501 to drive the connecting seat 502 and the side push plate 500, achieving high transmission accuracy and good self-locking, enabling fine adjustment and precise positioning in the Y direction. Its simple structure and ease of control make it suitable for high-cycle, high-precision applications. The connecting seat 502 is designed as a horizontal L-shape, with the lead screw motor 501 concealed at the bottom, further enhancing structural compactness and providing protection. The lead screw motor 501 and connecting seat 502 are connected by threads 503 and nuts. When the lead screw motor 501 moves, it horizontally pushes or retracts the lead screw, thereby moving the connecting seat 502 horizontally, which in turn moves the side push plate 500 located on the connecting seat 502 horizontally, thus pushing the material 6 horizontally.

[0047] Furthermore, the Y-direction positioning component 5 also includes a protective cover plate 504 disposed between the connecting seat 502 and the lead screw motor 501. The bottom surface of the connecting seat 502 is provided with a guide rail 505, and the top of the protective cover plate 504 is provided with a guide block 506 adapted to the guide rail 505.

[0048] This solution provides dust protection by installing a cover plate 504 between the connecting seat 502 and the lead screw motor 501; the guide rail 505 and the guide block 506 work together to ensure that the side push plate 500 moves smoothly and avoids shaking and deviation, further improving the accuracy of Y-axis positioning and the service life of the mechanism, realizing accurate pushing of material 6, and improving the precision and efficiency of the mechanism.

[0049] Furthermore, in this design, a sealing plate 507 can be installed on the side of the connecting seat 502 near the positioning support plate 205, and the bottom of the sealing plate 507 is fixedly connected to the top of the protective cover plate 504, thereby improving the structural stability of the Y-direction positioning assembly 5. Simultaneously, a protective cover 508 is installed at the bottom of the protective cover plate 504 to protect the bottom lead screw motor 501.
