[0002] In automated surface mount technology (SMT) manufacturing, the material feeding process often relies on automated guided vehicles (AGVs) for transporting and initially positioning the material bins. These bins are then connected to subsequent feeding operations via conveyor belts or other transport equipment to achieve automated production line operation. Currently, the positioning accuracy of mainstream AGVs in the industry is generally maintained at ±10mm.

[0022] Please see Figures 1 to 6 In one embodiment of this utility model, the feeding and positioning device for the material bin 200 is installed in the receiving machine and is used to position the material bin 200. The feeding and positioning device for the material bin 200 includes a base 10, a conveying assembly 20, a top plate 30, a first drive motor 40, a first transmission assembly 60, and two clamping units 50. The base 10 has a first direction (Y direction) and a second direction (X direction) that are perpendicular to each other; the conveying assembly 20 is disposed on the base 10 and is used to place the material box 200 and drive the material box 200 to move along the first direction; the top plate 30 is movably connected to the base 10, and a positioning post 31 protruding from the top plate 30 is installed on the top plate 30. The positioning post 31 moves upward to insert into the positioning hole at the bottom of the material box 200 to position the material box 200; the first drive motor 40 is fixedly installed on the base 10; two clamping units 50 are respectively disposed on both sides of the base 10; the first transmission assembly 60 is connected to the first drive motor 40 and the two sets of clamping units 50 for driving the two sets of clamping units 50 to move inward along the second direction to clamp the material box 200.

[0023] Specifically, in this embodiment, the base 10 serves as the installation and support foundation for the device, possessing a first perpendicular direction (the conveying direction of the material box 200) and a second perpendicular direction (the clamping direction of the material box 200), providing a stable assembly reference for all components. The conveying component 20 is mounted on the base 10, possessing the functions of carrying the material box 200 and driving its movement. It can drive the material box 200 to move along the first direction of the base 10, realizing the transfer of the material box 200 from the conveying position to the positioning position. The top plate 30 is mounted on the base 10 using a vertically movable connection method. A positioning post 31 protruding from the surface of the top plate 30 is fixedly installed on the top plate 30, and the positioning post 31 is adapted to the size and position of the positioning hole preset at the bottom of the material box 200. The first drive motor 40 serves as a power source, fixedly mounted on the base 10, providing power output for the movement of the clamping unit 50. The first transmission component 60 is a power transmission medium, establishing transmission connections with the power output end of the first drive motor 40 and the two sets of clamping units 50 respectively. Two clamping units 50 are respectively mounted on both sides of the base 10 along the second direction, and have the ability to translate along the second direction, for clamping and limiting from both sides of the material box 200.

[0024] The process of using the material bin 200 feeding and positioning device of this application is as follows: After the conveying component 20 is started, it moves the material bin 200 to the preset positioning operation area along the first direction, completing the material transfer before positioning. Lateral clamping action: The first drive motor 40 outputs power, which is transmitted to the two clamping units 50 through the first transmission component 60, driving the two clamping units 50 to move synchronously inward along the second direction until they are in contact with the side walls of the material bin 200, thus achieving lateral limiting of the material bin 200. Vertical positioning action: After the clamping units 50 complete the lateral clamping, the top plate 30 moves upward in the vertical direction, driving the positioning pins 31 on it to rise synchronously, so that the positioning pins 31 are accurately inserted into the corresponding positioning holes at the bottom of the material bin 200, completing the vertical positioning and fixing of the material bin 200.

[0025] In this embodiment, the dual positioning method of "lateral clamping (limiting lateral offset) + vertical positioning column 31 insertion (fixing vertical position)" effectively eliminates the lateral swaying and vertical displacement that may occur in the material box 200 during the conveying process, solves the problem of insufficient positioning accuracy in a single direction in the traditional positioning method, ensures the accuracy of the positioning position of the material box 200, and adapts to the positioning accuracy requirements of the subsequent feeding operation of the receiving machine.

[0026] Furthermore, the feeding and positioning device of the material box 200 also includes a second transmission component 70, which is connected to the first drive motor 40 and the top plate 30 respectively to drive the top plate 30 to move up and down; a plurality of guide posts 32 are installed on the lower surface of the top plate 30, and a plurality of guide members 11 are installed at the positions corresponding to the guide posts 32 on the base 10, and each guide member 11 is provided with a track hole for the guide post 32 to slide.

[0027] Specifically, the second transmission component 70 serves as a power transmission medium, with its two ends connected to the power output end of the first drive motor 40 and the top plate 30, respectively. It has the function of converting the power output by the first drive motor 40 into the power for the top plate 30 to move up and down. It can work with the first transmission component 60 to realize the branching transmission of power and provide power support for the vertical positioning action of the top plate 30.

[0028] The first drive motor 40 serves as the sole power source, connecting the first transmission assembly 60 and the second transmission assembly 70 via a "one-to-two" power transmission path. The first transmission assembly 60 drives the two clamping units 50 to translate along the second direction (achieving lateral clamping), while the second transmission assembly 70 moves the top plate 30 vertically (achieving vertical positioning). This single-motor, dual-drive design allows both lateral clamping and vertical positioning actions to be driven by the same power source, ensuring the synchronization and timing of the two actions and avoiding delays or deviations caused by multi-motor drives. This application, through its single-motor, dual-transmission assembly design, eliminates the need for additional drive motors, simultaneously achieving lateral clamping and vertical positioning actions. This simplifies the power system structure, reduces equipment cost and energy consumption, reduces the complexity of multi-motor collaborative control, and improves the stability of power transmission and the speed of action response.

[0029] Multiple guide posts 32 are fixedly installed on the lower surface of the top plate 30, distributed along the circumference of the top plate 30 or at a preset stress-balanced position. The post structure is adapted to the track hole size of the guide member 11, and moves up and down synchronously with the top plate 30, undertaking the guiding and limiting functions during the movement of the top plate 30. Multiple guide members 11 are fixedly installed on the base 10, corresponding one-to-one with the guide posts 32 on the lower surface of the top plate 30. Each guide member 11 has a track hole extending in the vertical direction. The inner wall of the track hole slides in fit with the outer wall of the guide post 32, providing a stable sliding path for the guide post 32.

[0030] The guide post 32 is fixedly connected to the top plate 30, and the guide member 11 is fixedly connected to the base 10. The guide post 32 and guide member 11 correspond one-to-one and slide together through the track holes, forming a vertical guide structure of "base 10 - guide member 11 - guide post 32 - top plate 30". This structure uses the base 10 as a fixed reference. By sliding the guide post 32 within the track holes, the top plate 30 is restricted to moving only vertically, preventing lateral offset or tilting during vertical movement. This ensures that the positioning post 31 on the top plate 30 is accurately aligned with the positioning hole at the bottom of the material box 200.

[0031] The positioning process is described in detail below: The conveying component 20 first transports the material box 200 to the preset area; then, the first drive motor 40 drives the clamping unit 50 to horizontally clamp the material box 200 (limiting lateral displacement) via the first transmission component 60; immediately afterward, the first drive motor 40 drives the top plate 30 to move upward via the second transmission component 70. At this time, the guide column 32 rises vertically synchronously along the track hole of the guide member 11, ensuring that the positioning column 31 is accurately inserted into the positioning hole of the material box 200 (achieving vertical fixation). The newly added second transmission component 70 and guide structure provide power support and accuracy assurance for the vertical positioning action, making the dual positioning process of "horizontal clamping - vertical positioning" more complete and reliable.

[0032] Furthermore, the first transmission assembly 60 includes a connecting plate 61, two sliding bars 62, two movable blocks 63, and two fixed frames 64; the two sliding bars 62 are spaced apart on the base 10 and are slidably connected to the base 10 along a first direction; both ends of the connecting plate 61 are fixed to the sliding bars 62, and the connecting plate 61 is tractively connected to the first drive motor 40; the two movable blocks 63 are respectively fixedly installed on the two sliding bars 62; each movable block 63 has a zigzag-shaped track groove 631, and each fixed frame 64 can be slidably connected to the base 10 along a second direction. A rotating shaft 65 is installed on the side of the fixed frame 64 near the track groove 631, and the rotating shaft 65 extends into the track groove 631; the first drive motor 40 drives the connecting plate 61, the sliding bars 62, and the movable blocks 63 to slide along a preset direction, thereby driving the two fixed frames 64 to move inward, and two clamping units 50 are respectively installed on the two fixed frames 64.

[0033] Specifically, the connecting plate 61 has a long strip structure, with both ends fixedly connected to two sliding bars 62, and the middle or a preset position connected to the power output end of the first drive motor 40 (e.g., via a lead screw, gear, etc.). It is responsible for power transmission and synchronous driving of the sliding bars 62, and can move along a preset direction along with the power output of the first drive motor 40. The two sliding bars 62 adopt the same long strip structure, spaced apart and parallel to each other on the base 10. They are slidably connected to the base 10 along the first direction (only able to move in the first direction, restricting displacement in other directions) through structures such as slide rails and sliders, providing an installation carrier and movement guide for the movable block 63. Two movable blocks 63 are fixedly installed at preset positions of the two sliding bars 62 (e.g., near the clamping unit 50). Each movable block 63 has a zigzag track groove 631. The track groove 631 is composed of a section extending in the first direction and a section inclined inward in the second direction, providing a sliding path for the rotating shaft 65 and realizing the conversion of the movement direction from "movement of the sliding bar 62 in the first direction" to "movement of the fixed frame 64 in the second direction". The two fixed frames 64 serve as the mounting bases of the clamping unit 50. They are slidably connected to the base 10 in the second direction through structures such as slide rails and guide grooves (they can only translate in the second direction). A rotating shaft 65 (e.g., a cylindrical pin) is fixedly installed on the side near the track groove 631 of the movable block 63. The rotating shaft 65 can slide or roll freely in the track groove 631. The two fixed frames 64 are fixedly connected to the two clamping units 50 one-to-one, driving the clamping units 50 to move synchronously in the second direction.

[0034] In this embodiment, the power transmission chain is as follows: first drive motor 40 → connecting plate 61 → two sliding bars 62 → two movable blocks 63 → rotating shaft 65 → two fixed frames 64 → two clamping units 50, forming a complete power transmission path. This ensures that the motor power can be sequentially transmitted to the clamping units 50, achieving synchronous power transmission. When the sliding bar 62 moves along the first direction, it drives the movable block 63 to move synchronously along the first direction. The zigzag track groove 631 on the movable block 63 moves with the movable block 63. The inner wall of the track groove 631 generates a lateral thrust on the rotating shaft 65. When the rotating shaft 65 slides from the first direction section of the track groove 631 into the inclined section, the thrust direction changes from the first direction to the inner side of the second direction, thereby pushing the fixed frame 64 to translate inward along the second direction. This ultimately achieves a precise conversion from "linear motion in the first direction" to "linear motion in the second direction." Furthermore, the symmetrical design of the two sliding bars 62 and the movable block 63 ensures that the two fixed frames 64 move inward synchronously, preventing the clamping unit 50 from shifting.

[0035] The sliding bar 62 is slidably connected to the base 10 along a first direction, and the fixed frame 64 is slidably connected to the base 10 along a second direction. The base 10, by constraining the movement directions of the sliding bar 62 and the fixed frame 64, provides a stable reference for the power transmission and motion conversion of the first transmission assembly 60, preventing lateral offset or tilting of the assembly during movement and ensuring transmission accuracy. The sliding bar 62 and the base 10 can be slidably connected via a slide rail and a slider. Similarly, the fixed frame 64 and the base 10 can also be slidably connected via a slide rail and a slider.

[0036] In this embodiment, the track groove 631 includes a first straight segment 6311, an inclined segment 6312, and a second straight segment 6313 connected in sequence. Both the first straight segment 6311 and the second straight segment 6313 are parallel to a first direction. The distance between the first straight segment 6311 and the clamping unit 50 is less than the distance between the second straight segment 6313 and the clamping unit 50.

[0037] Specifically, in this embodiment, the track groove 631 is formed on the movable block 63, and is generally zigzag-shaped, consisting of a first straight segment 6311, an inclined segment 6312, and a second straight segment 6313 connected in sequence. Each segment is an integrally formed groove structure, and the first straight segment 6311 and the second straight segment 6313 are both parallel to the first direction defined by the base 10 (the conveying direction of the material box 200). In terms of position, the distance between the first straight segment 6311 and the clamping unit 50 is less than the distance between the second straight segment 6313 and the clamping unit 50, that is, the first straight segment 6311 is closer to the clamping unit 50, and the second straight segment 6313 is farther away from the clamping unit 50. The second straight segment 6313 is the "far clamping end section" of the track groove 631, corresponding to the final position where the fixed frame 64 drives the clamping unit 50 to complete the clamping action. When the rotating shaft 65 is located in this section, the clamping unit 50 is tightly fitted with the side wall of the material box 200, achieving lateral limitation. The first straight segment 6311 is the "near clamping end section" of the track groove 631, corresponding to the initial standby position of the clamping unit 50. When the rotating shaft 65 is in this section, the clamping unit 50 is in a state far away from the material box 200, which does not affect the conveying of the material box 200. The inclined segment 6312 is the transition section connecting the first straight segment 6311 and the second straight segment 6313. It is smoothly inclined, and its extension direction gradually approaches the clamping unit 50 from the second straight segment 6313 to the first straight segment 6311. It is used to realize the smooth transition of the rotating shaft 65 from the "near clamping end" to the "far clamping end", and complete the change of motion direction and power transmission.

[0038] This embodiment uses a segmented structure of "first straight segment 6311 (standby) - inclined segment 6312 (advance) - second straight segment 6313 (clamping)" to clearly define the different stages of the clamping action. This allows the movement distance of the clamping unit 50 to be precisely controlled by the length and inclination angle of the inclined segment 6312 of the track groove 631, ensuring that the final position of the clamping unit 50 is consistent each time it is clamped. This avoids over-clamping or under-clamping caused by uneven power transmission, improves the consistency and accuracy of the lateral clamping of the material box 200, and provides a stable lateral reference for vertical positioning.

[0039] Furthermore, the second transmission assembly 70 includes multiple inclined blocks 71 and a supporting member 72. The inclined blocks 71 are fixedly installed on the lower surface of the top plate 30, and the supporting member 72 is fixedly installed on the sliding bar 62. The inclined blocks 71 have a first surface 711, a second surface 712, and a connecting inclined surface 713 facing the supporting member 72. The distance between the first surface 711 and the sliding bar 62 is less than the distance between the second surface 712 and the sliding bar 62. The connecting inclined surface 713 connects the first surface 711 and the second surface 712. The supporting member 72 slides with the sliding bar 62 in a first direction. When the supporting member 72 abuts against the second surface 712, the positioning post 31 on the top plate 30 is located outside the positioning hole. When the supporting member 72 abuts against the first surface 711, the positioning post 31 on the top plate 30 is inserted into the positioning hole to position the material box 200.

[0040] Specifically, multiple inclined blocks 71 are fixedly installed on the lower surface of the top plate 30, distributed along the circumference of the top plate 30 or at a position where the force is balanced (offset from the guide post 32 to avoid interference). Each inclined block 71 has a first surface 711, a second surface 712, and a connecting inclined surface 713. The distance between the first surface 711 and the sliding bar 62 is small, which is the "lower end face" of the inclined block 71, corresponding to the state where the top plate 30 rises to the positioning position. The distance between the second surface 712 and the sliding bar 62 is large, which is the "higher end face" of the inclined block 71, corresponding to the state where the top plate 30 descends to the initial position. The connecting inclined surface 713 is smoothly inclined, with both ends integrally connected to the first surface 711 and the second surface 712, forming a transition inclined surface from the second surface 712 to the first surface 711, providing a sliding guide path for the top support 72. The top support 72 is fixedly installed on the sliding bar 62 (corresponding to the inclined top block 71 one by one). It moves synchronously with the sliding bar 62 along the first direction and can abut against the second surface 712, the connecting inclined surface 713, and the first surface 711 of the inclined top block 71 in sequence. The abutting force pushes the inclined top block 71 to drive the top plate 30 to move up and down. When the top holding member 72 moves along the first direction (horizontal direction) with the sliding bar 62, its contact surface with the inclined top block 71 transitions from the second surface 712 (high position) through the connecting inclined surface 713 to the first surface 711 (low position). Due to the inclined structure of the connecting inclined surface 713, the horizontal thrust is converted into a vertical upward thrust, which pushes the inclined top block 71 to drive the top plate 30 to rise in the vertical direction. Conversely, when the sliding bar 62 moves in the opposite direction, and the top holding member 72 returns from the first surface 711 to the second surface 712 through the connecting inclined surface 713, the top plate 30 descends in the vertical direction under its own weight or the action of the reset structure, realizing the powerless conversion from "horizontal movement" to "vertical movement".

[0041] When the sliding bar 62 moves along the first direction, it simultaneously performs two functions: first, it drives the fixed frame 64 and clamping unit 50 to move inward along the second direction via the first transmission component 60 (horizontal clamping of the material box 200); second, it drives the top support 72 via the second transmission component 70 to push the top plate 30 upward (vertical positioning of the material box 200). That is, "horizontal clamping" and "vertical positioning" are triggered synchronously by the same horizontal movement of the sliding bar 62, without the need for additional timing control, achieving seamless connection between the two positioning actions. The lifting and lowering of the top plate 30 is achieved by using the power of the sliding bar 62 driven by the first drive motor 40, without the need for additional vertical drive motors or hydraulic or pneumatic devices, reducing the number of power components, simplifying the equipment structure, reducing manufacturing and maintenance costs, and avoiding the complexity of multi-power source coordinated control. The height difference between the first surface 711 and the second surface 712 of the inclined top block 71 is fixed. When the top holding member 72 slides along the connecting inclined surface 713, the rising height of the top plate 30 is strictly controlled by the accuracy of the inclined surface of the inclined top block 71, ensuring that the rising height of the top plate 30 is consistent each time it is positioned. The positioning post 31 can be accurately inserted into the positioning hole of the material box 200, avoiding positioning failure or damage to the material box 200 due to the deviation in rising height, and improving the vertical positioning accuracy. The top holding member 72 and the inclined top block 71 achieve a smooth transition abutment through the connecting inclined surface 713, and the horizontal thrust is gradually converted into a vertical thrust, avoiding the impact load generated by rigid collision, reducing the wear of the inclined top block 71, the top holding member 72 and the top plate 30. At the same time, with the guiding effect of the guide post 32 and the guide member 11, the lifting process of the top plate 30 is more stable, and the overall service life of the device is extended.

[0042] Furthermore, there are two positioning posts 31, one of which has a rotating structure at the top and the other has a polygonal structure at the top.

[0043] Specifically, in this embodiment, two positioning posts 31 are provided, both fixedly installed on the upper surface of the top plate 30 and protruding from the top plate 30. Their installation positions correspond one-to-one with the two pre-set positioning holes at the bottom of the material box 200. They rise and fall synchronously with the up-and-down movement of the top plate 30, and are the core execution components for achieving precise vertical positioning of the material box 200. The top of the first positioning post 31 adopts a rotating body structure (such as a cylinder, frustum, hemisphere, etc.). This structure has no sharp edges and a smooth curved surface on the outer surface, providing good guidance and fault tolerance. The top of the second positioning post 31 adopts a polygonal structure (such as a quadrangular prism, hexagonal prism, triangular prism, or irregular prism, etc.). This structure has a clear edge and corner outline, and the outer surface is an asymmetrical structure formed by planar splicing, providing precise anti-rotation and positioning limit functions. The two positioning posts 31 form a "two-point positioning" structure, which can more stably limit the vertical displacement and horizontal sway of the material box 200 compared with single-point positioning. At the same time, the differentiated functions of "rotational body guidance + polygonal anti-rotation" complement each other, which not only solves the fault tolerance problem during docking, but also solves the anti-rotation problem after positioning, forming a complete vertical positioning guarantee system and improving the overall positioning reliability of the device.

[0044] Furthermore, the top support 72 includes a mounting base 721 and an abutment shaft 722. The mounting base 721 is fixedly mounted on the sliding bar 62, and the abutment shaft 722 is rotatably connected to the mounting base 721.

[0045] Specifically, in this embodiment, the top support 72 includes a mounting base 721 and an abutment shaft 722. It is a key actuator in the second transmission assembly 70 that cooperates with the inclined top block 71, and it plays a connecting role in converting the horizontal power of the sliding bar 62 into the vertical power of the top plate 30. The mounting base 721 adopts a rigid block or bracket structure, serving as the mounting carrier for the abutment shaft 722. It is fixedly installed at a preset position on the sliding bar 62 by bolts, welding, or other methods, forming a fixed connection with the sliding bar 62. It moves synchronously with the sliding bar 62 along the first direction, ensuring that the movement trajectory of the abutment shaft 722 is consistent with that of the sliding bar 62. The abutment shaft 722 has a cylindrical rod-like structure and is installed on the mounting base 721 through rotating connecting parts such as bearings and bushings. It can rotate freely around its own axis, and its outer circumferential surface is a smooth arc surface, used to directly contact the second surface 712, the connecting inclined surface 713, and the first surface 711 of the inclined top block 71 to transmit thrust.

[0046] The abutment shaft 722 can rotate freely. When it contacts the inclined push block 71, rolling friction replaces traditional sliding friction, which greatly reduces the friction coefficient and contact resistance between the two, reduces wear on the surface of the inclined push block 71 and the outer peripheral surface of the abutment shaft 722, avoids component deformation or precision reduction caused by long-term friction, extends the service life of the support member 72 and the inclined push block 71, and reduces equipment maintenance frequency and cost.

[0047] Furthermore, the feeding and positioning device of the material bin 200 also includes multiple elastic elements 80, which are connected to the base 10 and the inclined top block 71, or the elastic elements 80 are connected to the base 10 and the top plate 30.

[0048] Specifically, the elastic element 80 is a component with elastic reset function (such as a tension spring), and multiple such elements are provided. There are two optional installation positions: Option 1: The elastic element 80 is connected to the base 10 and the inclined top block 71 at both ends, arranged in a vertical direction. One end is fixed to the base 10, and the other end is connected to the lower surface or side of the inclined top block 71. Option 2: The elastic element 80 is connected to the base 10 and the top plate 30 at both ends, arranged in a vertical direction, with one end fixed to the base 10 and the other end connected to the lower surface of the top plate 30. In both schemes, the elastic element 80 is in a pre-stretched state, which provides downward pulling force to the top plate 30, reducing vibration of the top plate 30, keeping it in a stable state, reducing the impact of vibration on the positioning accuracy of the top plate 30, and improving the adaptability of the device in dynamic operating scenarios. The pre-tightening force of the elastic element 80 ensures that the inclined top block 71 and the top holding member 72 always maintain a tight contact, eliminating the gap between them. When the top holding member 72 slides along the inclined surface 713 connecting the inclined top block 71, the pre-tightening force of the elastic element 80 can avoid delays or jamming in the transmission of thrust due to gaps, ensuring that the rising height of the top plate 30 is accurately controllable, and that the positioning column 31 can be stably inserted into the positioning hole of the material box 200, improving the consistency and reliability of vertical positioning.

[0049] Furthermore, the fixing frame 64 includes a first plate 641 and a second plate 642. One end of the first plate 641 is connected to the second plate 642, and the other end extends toward the movable block 63. The rotating shaft 65 is located at one end of the second plate 642 near the sliding bar 62. The clamping unit 50 is installed on the second plate 642.

[0050] Specifically, the fixing frame 64 is a T-shaped or bent rigid structure, which is formed integrally or fixedly connected by the first plate 641 and the second plate 642, and serves as the mounting carrier and transmission connection component of the clamping unit 50. The first plate 641 is elongated, with one end fixedly connected to the second plate 642 perpendicularly, and the other end extending towards the movable block 63 to form an "extension arm" of the fixing frame 64, which is used to shorten the distance between the fixing frame 64 and the movable block 63 and ensure the precise fit between the rotating shaft 65 and the track groove 631 of the movable block 63. The second plate 642 has a plate-like structure, with one end connected to the first plate 641 and the other end being a free end. A rotating shaft 65 (compatible with the zigzag track groove 631 of the movable block 63) is fixedly installed on the side closer to the movable block 63 (or sliding bar 62), while the side farther from the movable block 63 is used to install the clamping unit 50. Simultaneously, the second plate 642 and the base 10 are slidably connected along the second direction via slide rails, guide grooves, and other structures, restricting its movement to only the lateral (clamping direction). The fixed frame 64 performs the dual functions of "power transmission" and "support for the clamping unit 50"—it receives the power transmitted from the movable block 63 through the rotating shaft 65, driving itself to move along the second direction, and then transmits the power to the clamping unit 50, realizing the lateral clamping action of the material box 200.

[0051] Furthermore, the clamping unit 50 includes at least two clamping blocks 51; the clamping blocks 51 are L-shaped and include a first wall 511 and a second wall 512, the first wall 511 is connected to the second plate 642, and the second wall 512 extends toward the sliding bar 62.

[0052] Specifically, in this embodiment, the clamping unit 50 serves as the execution component for the lateral clamping of the material box 200. Each clamping unit 50 includes at least two clamping blocks 51, which are spaced apart along the conveying direction (first direction) of the material box 200 to form a multi-point clamping structure on the side wall of the material box 200, ensuring that the clamping force is applied evenly to the material box 200. Each clamping block 51 has an "L"-shaped bent structure, consisting of an integrally formed first wall 511 and a second wall 512. The first wall 511 is a vertical or inclined mounting wall surface, which is fixedly connected to the second plate 642 of the fixing frame 64 by bolts, welding, or other means, and undertakes the assembly and fixing function of the clamping block 51 and the fixing frame 64, ensuring that the clamping block 51 moves synchronously with the fixing frame 64 along the second direction. The second wall 512 is a horizontal or clamping wall surface at a preset angle to the first wall 511. It extends from the first wall 511 toward the sliding strip 62 (in the direction of the center of the material box 200). The wall surface is flat and fits the side wall of the material box 200. It is the key part that directly contacts the material box 200 and applies clamping force. The clamping block 51 is rigidly connected to the second plate 642 of the fixing frame 64 through the first wall 511. When the fixing frame 64 moves inward along the second direction (lateral), it directly drives the clamping block 51 to move synchronously. Since each clamping unit 50 is provided with at least two clamping blocks 51 and is distributed at intervals along the first direction, the fixing frame 64 can ensure that the clamping force of the clamping blocks 51 on the material box 200 is evenly distributed through multi-point transmission, avoiding excessive local force or displacement of the material box 200 caused by single-point clamping.

[0053] Furthermore, the conveying component 20 includes a belt drive pair, and the feeding and positioning device of the material box 200 also includes a second drive motor 90, which is connected to the belt drive for belt transmission.

[0054] Specifically, in this embodiment, the conveying component 20 adopts a belt drive pair structure, mainly including a driving roller, a driven roller, a transmission belt, and a roller shaft support. The driving roller and the driven roller are installed parallel to each other on the base 10 through the roller shaft support, with their axial direction consistent with the second direction (clamping direction). The transmission belt is wrapped around the outer periphery of the driving roller and the driven roller, forming a horizontal material box 200 bearing and conveying surface. The surface of the transmission belt is flat and has a certain friction (which can be enhanced by surface texture treatment or material selection) to ensure that the material box 200 does not easily slip after being placed. The second drive motor 90 is an independent power source, fixedly installed at a preset position on the base 10 (near the driving roller). The motor output shaft is connected to the driving roller shaft of the belt drive pair through a coupling, gear transmission, or belt pulley transmission, etc. It has adjustable speed and direction, and can provide stable power output for the belt drive pair. The second drive motor 90 and the belt drive pair form a complete conveying power chain of "power source - transmission mechanism - execution component". After the second drive motor 90 starts, the power is transmitted to the drive roller through the transmission structure, which drives the drive roller to rotate around its own axis. The drive roller drives the transmission belt to circulate through the friction with the transmission belt, which in turn drives the material box 200 placed on the transmission belt to move synchronously in the first direction, so as to realize the automated conveying of the material box 200.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
