Technical Field

[0001] This utility model relates to the field of chip mounting equipment technology, and in particular to a tray flipping device. Background Technology

[0002] In fields such as electronic component manufacturing and SMT assembly that rely on tray feeding, the receiving machine is a key piece of equipment to ensure continuous material supply on the production line. Its core operation process is as follows: first, the old tray (the tray with insufficient tape remaining) is removed from the tray and transferred to the receiving station to connect the remaining tape to the new tray. Finally, the connected new tray is returned to the original tray location to maintain the continuity of subsequent material supply. Currently, new material trays are placed vertically in the tray. Vertical tray placement has limitations in terms of positioning. Therefore, our company designed a tray for horizontally placed new material trays, which solves the problem of inaccurate positioning. However, the existing tray transfer devices of receiving machines are designed for traditional vertically placed trays (tray axis horizontal), and their structure and operating logic cannot adapt to the tray handling requirements of horizontally placed trays (tray axis vertical).

[0003] Therefore, the industry urgently needs a tray flipping device that can adapt to horizontally placed trays (with the tray axis vertical). Utility Model Content The main purpose of this invention is to propose a material tray flipping device, which is designed to be compatible with horizontally placed material boxes.

[0004] To achieve the above objectives, the present invention proposes a tray flipping device, comprising: Mounting rack; A movable plate, which is slidably connected to the mounting frame, and the sliding direction is vertical; A worktable is rotatably connected to the movable plate. The worktable can switch between a vertical and a horizontal state. The worktable has a central rotating shaft, which is used to insert into the central hole of the material tray to position the material tray. When the worktable is in a horizontal state, it receives the horizontally placed material tray. When the worktable is in a vertical state, it conveys the material strip of the material tray to the receiving module.

[0022] This utility model proposes a tray flipping device to adapt to a material box 300 with horizontally arranged trays (e.g., Figure 1 When the material is limited, the robotic arm slightly lifts the horizontally placed material tray 200 from below and takes it out of the material tray 300. Then, the material tray is placed horizontally on the material tray flipping device of this application for subsequent processes (connecting the material strip on the new material tray with the old material strip).

[0023] Please see Figures 2 to 10 In one embodiment of this utility model, the material tray 200 flipping device includes a mounting frame 10, a movable plate 20, and a worktable 30. The movable plate 20 is slidably connected to the mounting frame 10, and the sliding direction is vertical. The worktable 30 is rotatably connected to the movable plate 20. The worktable 30 can switch between a vertical state and a horizontal state. The worktable 30 has a central rotating shaft 31, which is used to insert into the central hole of the material tray 200 to position the material tray 200. When the worktable 30 is in a horizontal state, it receives the horizontally placed material tray 200. When the worktable 30 is in a vertical state, it conveys the material strip 201 of the material tray 200 to the receiving module.

[0024] Specifically, in this embodiment, the mounting frame 10 possesses stable structural strength (typically made of metal materials such as steel or aluminum alloy), and serves to provide a sliding mounting reference and support for the movable plate 20. The structural design of the mounting frame 10 must adapt to the vertical sliding requirements of the movable plate 20. A guide structure (such as a guide rail or slide rail) is typically provided on the side connected to the movable plate 20 to ensure that the movable plate 20 does not deviate during sliding, laying a stable foundation for the subsequent precise placement and orientation changes of the material tray 200. The movable plate 20 can move smoothly vertically (up and down) through the cooperation of the slider and the guide structure of the mounting frame 10, and the travel distance can be flexibly adjusted according to actual needs. Simultaneously, the movable plate 20 also functions as the mounting worktable 30, providing reliable support for the rotation of the worktable 30, and is the core transfer component connecting the mounting frame 10 and the worktable 30. The worktable 30 is a key component that directly interacts with the material tray 200. The worktable 30 is rotatably connected to the movable plate 20, switching between a vertical and a horizontal state. A central rotating shaft 31 is installed at the center of the worktable 30. The diameter of the shaft matches the inner diameter of the center hole of the material tray 200 (with minimal clearance). When the material tray 200 is placed, the central rotating shaft 31 can be inserted into the center hole of the material tray 200 to achieve precise positioning from the center of the material tray 200, preventing the material tray 200 from shifting horizontally during movement or rotation. The worktable 30 has two states to meet different working requirements—in the horizontal state, the tray surface is parallel to the working surface and can directly receive the material tray 200 from the horizontally placed material box (at this time, the material tray 200 is in a horizontally placed state and is in contact with the tray surface of the worktable 30); in the vertical state, the tray surface is perpendicular to the ground, and the material tray 200 rotates to a vertical position synchronously with the worktable 30, and its material belt 201 can be aligned with the feed port of the receiving module for easy conveying of the material belt 201.

[0025] In this embodiment, through the vertical sliding of the movable plate 20 and the horizontal material handling design of the worktable 30, the device can perfectly adapt to the material tray 200 handling requirements of horizontally placed material boxes. The horizontal worktable 30 can directly receive the horizontal material tray 200 output from the material box, and the positioning structure of the central rotating shaft 31 ensures that the material tray 200 does not shift during handling, solving the pain point of traditional devices being unable to adapt to horizontally placed material boxes and filling the gap between the horizontal material box and the receiving module. The 90° precise rotation design of the worktable 30 enables a smooth transition of the material tray 200 from horizontal to vertical placement. Combined with the positioning of the central rotating shaft 31, the material tray 200 does not shift or shake during the transition, effectively avoiding the problem of material spillage or misalignment of the conveyor belt 201 caused by the tilting of the material tray 200, ensuring the integrity of the material tray 200 and the material, and providing a key guarantee for the stability of the subsequent conveyor belt 201. The connection and operation logic of each component of the device are simple and clear. The vertical sliding of the movable plate 20 and the rotation of the worktable 30 are both controllable mechanical actions, making operation easy. Furthermore, the core positioning structure (central rotating shaft 31) is simple and reliable in design, not easily damaged, reducing the maintenance cost of the device. Simultaneously, the entire device's operation can be linked through an automated control system (such as coordinating with the feeding rhythm of the material bin and the feeding requirements of the receiving module), reducing manual intervention and further improving the convenience and reliability of operation. When the worktable 30 switches to a vertical state, the material tray 200 becomes vertical synchronously with the worktable 30, and its material belt 201 can be directly aligned with the feeding port of the receiving module without additional adjustment of the material tray 200 position. This shortens the conveying path of the material belt 201, reduces the risk of failure during conveying (such as jamming or offset of the material belt 201), improves the feeding efficiency of the receiving module, and thus improves the overall working efficiency of the receiving machine.

[0026] Furthermore, the material tray 200 flipping device also includes a first slide rail 40, a first motor 41, and a first transmission assembly 42; the first slide rail 40 is horizontally arranged, and the first transmission assembly 42 is connected to the first motor 41 and the mounting bracket 10 respectively; the first motor 41 is used to drive the mounting bracket 10 to slide horizontally along the first slide rail 40 through the first transmission assembly 42.

[0027] Specifically, in this embodiment, there can be two first slide rails 40, spaced apart below the mounting frame 10. A slider adapted to each first slide rail 40 is mounted on the lower surface of the mounting frame 10. The first slide rail 40 is a linear slide rail structure, made of high-strength alloy material (such as stainless steel or wear-resistant aluminum alloy), possessing excellent wear resistance and deformation resistance. The first slide rail 40 is horizontally positioned and mounted on the bottom shell of the receiving machine. The length of the slide rail needs to be adapted to the horizontal movement stroke of the mounting frame 10 (usually set according to the horizontal distance between the horizontally placed material box and the receiving module, such as 0.5-2m). The first motor 41 can be a servo motor or a stepper motor, featuring controllable speed and high positioning accuracy, enabling precise control of the horizontal position of the mounting frame 10. The first transmission component 42, as the core component connecting the first motor 41 and the mounting frame 10, can adopt a synchronous belt and synchronous pulley structure, offering smooth transmission, low maintenance costs, and suitability for scenarios with long horizontal movement strokes. The first motor 41 is used to move the mounting frame 10 horizontally. For example, after the workbench 30 receives the new material strip 201 tray 200 in a horizontal position, the workbench 30 rotates to adjust to a vertical position, and then the mounting frame 10 is moved to move the new material tray 200 on the mounting frame 10 and the workbench 30 to the position of the new material cutting component to cut the empty part of the new material strip 201. After the cutting is completed, the first motor 41 drives the mounting frame 10, the workbench 30 and the tray 200 to the part where they are connected with the old material strip 201, thereby completing the connection of the new and old material strips 201 for use in subsequent processes.

[0028] Furthermore, the material tray 200 turning device also includes a material head fixing component 50, which is installed on the movable plate 20 and is used to position the material head of the material strip 201 of the material tray 200.

[0029] Specifically, in this embodiment, the material head fixing component 50, as a key component connecting the new material tray 200 with the old material and ensuring the precise cutting and splicing of the new and old material strips 201, is installed on the side of the movable plate 20 near the workbench 30 and corresponding to the new and old cutting components of the receiving module. Its core function is to position the head of the material strip 201, ensuring its precise alignment with the cutting station of the new and old cutting components and the docking position of the old material, thus ensuring the normal and accurate operation of subsequent processes. The material head fixing component 50 can be rigidly connected to the movable plate 20 via locking bolts. Figure 5 and Figure 7 As shown, the head of the material strip 201 on the material tray 200 extends from the position of the material tray 200 to the head fixing component 50, and the head of the material strip 201 is positioned by the head fixing component 50.

[0030] Furthermore, the mounting frame 10 includes a horizontal base plate 11, a vertical plate 12, and two side plates 13. The vertical plate 12 is vertically connected to one end of the horizontal base plate 11, and the two side plates 13 are respectively disposed on both sides of the horizontal base plate 11 to connect the horizontal base plate 11 and the vertical plate 12. The movable plate 20 is slidably connected to the side of the vertical plate 12 near the vertical plate 12.

[0031] Specifically, the mounting frame 10, serving as the basic support frame of the device, adopts an integrated frame structure consisting of a horizontal base plate 11, a vertical plate 12, and two side plates 13. All components are made of high-strength steel (such as Q235 steel plate) or aluminum alloy profiles, and are connected by welding or bolts to form a rigid whole. The horizontal base plate 11 is a rectangular plate structure and is the basic component connecting the mounting frame 10 to the first slide rail 40. The length of the base plate must be adapted to the sliding stroke of the first slide rail 40 to ensure no end interference during sliding; the width must cover the installation requirements of the vertical plate 12 and the two side plates 13; and the thickness must ensure load-bearing strength to support the total weight of the movable plate 20, the worktable 30, and the material tray 200. The surface of the base plate has multiple mounting holes: the bottom has bolt holes for connecting to the slider, used for rigid connection with the slider of the first slide rail 40. The vertical plate 12 is a vertically arranged rectangular plate and is the core load-bearing component for the sliding connection of the movable plate 20, vertically connected to one end of the horizontal base plate 11. The height of the vertical plate 12 must be adapted to the vertical sliding stroke of the movable plate 20 to prevent it from detaching when sliding to the end; its width must be consistent with the width of the horizontal base plate 11; and its thickness must ensure rigidity when sliding with the movable plate 20 to prevent sliding jamming due to bending under force. The two side plates 13 are symmetrically arranged triangular or trapezoidal plates, respectively connected to both sides of the horizontal base plate 11 and fixedly connected to the two side edges of the vertical plate 12, forming a triangular support structure. The thickness of the side plates 13 must ensure support strength; its height must be consistent with the height from the bottom of the vertical plate 12 to the horizontal base plate 11 (i.e., the installation height of the vertical plate 12); and its width must be compatible with the width of the horizontal base plate 11, covering the two side edges of the base plate. The connection points between the side plates 13 and the horizontal base plate 11 and the vertical plate 12 are fully welded or bolted to ensure connection rigidity and prevent frame deformation during device operation (such as when the movable plate 20 slides or the worktable 30 rotates).

[0032] In this embodiment, a triangular support is formed by the frame structure of the horizontal base plate 11, the vertical plate 12, and the two side plates 13, which significantly improves the torsional stiffness and effectively prevents the mounting frame 10 from deforming due to the lateral force generated when the movable plate 20 slides or the worktable 30 rotates. Even when the worktable 30 rotates to a vertical position and carries the material tray 200, the vertical plate 12 does not bend significantly, ensuring the parallelism of the sliding guide rail of the movable plate 20 and preventing the movable plate 20 from sliding and jamming or deviating due to frame deformation, thus ensuring the accuracy of the material tray 200 in picking up and placing and changing its posture.

[0033] Furthermore, the material tray 200 flipping device also includes a second slide rail 60, a second motor 61, and a second transmission component 62; the second slide rail 60, the second motor 61, and the second transmission component 62 are connected to the vertical plate 12, and the second motor 61 is used to drive the movable plate 20 to slide along the second slide rail 60.

[0034] Specifically, in this embodiment, the second slide rail 60, the second motor 61, and the second transmission assembly 62 together constitute the vertical drive system of the movable plate 20, all connected to the vertical plate 12 of the mounting bracket 10. Their core function is to provide precise guidance and power for the movable plate 20 to slide vertically. The second slide rail 60 is a guide component for the vertical sliding of the movable plate 20, fixedly connected to the side (inner side) of the vertical plate 12 closest to the movable plate 20. It is typically configured as two parallel linear guide rails (or grooves) extending along the height direction of the vertical plate 12. The spacing between the two second slide rails 60 must be adapted to the width of the movable plate 20 to ensure balanced force on the movable plate 20 and prevent jamming due to uneven force during sliding. The second motor 61 is the power source for the vertical sliding of the movable plate 20. It is installed on the side of the vertical plate 12 away from the movable plate 20 (outer side). It is usually a servo motor (or stepper motor), which has the characteristics of controllable speed and high positioning accuracy. The output power can be matched according to the weight of the movable plate 20 and the load (including the worktable 30 and the material tray 200) to ensure sufficient power and smooth operation. The motor is equipped with an encoder, which can provide real-time feedback on the rotation angle and speed, so as to facilitate linkage with the control system and achieve precise control of the vertical position of the movable plate 20. The second transmission component 62 is a power transmission component, which is connected between the second motor 61 and the movable plate 20. It is used to convert the rotational power of the second motor 61 into the vertical linear motion of the movable plate 20. It can be a ball screw + screw nut.

[0035] Furthermore, the tray 200 tilting device also includes a third motor 70 and a third transmission assembly 71. The third transmission assembly 71 is connected to the third motor 70 and the worktable 30. The third motor 70 is used to drive the worktable 30 to rotate.

[0036] Specifically, in this embodiment, the third motor 70 and the third transmission component 71 together constitute the rotation drive system of the worktable 30. Their core function is to provide precise power for the worktable 30 to switch between horizontal and vertical states, ensuring smooth and reliable posture transitions for the material tray 200. The third motor 70 is the power source for the rotation of the worktable 30, installed on the side of the movable plate 20 near the rotation axis of the worktable 30 (avoiding interference with other components). It can be a stepper motor or a servo motor. Stepper motors are simple to control and moderately cost-effective, suitable for scenarios where the rotation angle is fixed (90°) and the speed requirement is stable. Servo motors offer higher positioning accuracy and speed controllability, suitable for scenarios with stringent requirements for rotational stability (such as preventing material swaying in the material tray 200). The third transmission component 71 is the power transmission medium, connected between the output shaft of the third motor 70 and the rotation axis of the worktable 30. It smoothly transmits the rotational power of the motor to the worktable 30 and can employ gear transmission sets, synchronous belts and pulleys, worm gears, etc. Furthermore, the workbench 30 includes a mounting plate 32 and a placement box 33. The placement box 33 is fixedly mounted on the mounting plate 32 to provide a flat surface for placing the material tray 200; the central rotating shaft 31 is slidably mounted on the mounting plate 32.

[0037] Specifically, in this embodiment, the mounting plate 32 serves as the base support plate for the workbench 30. It is made of metal (such as aluminum alloy or steel plate) and is circular or rectangular (to accommodate the installation requirements of the placement box 33 and the rotating shaft). Its thickness must ensure structural rigidity to prevent bending and deformation of the material tray 200. One side of the mounting plate 32 is connected to the rotating shaft mounting seat of the movable plate 20 via a bearing (to enable the overall rotation of the workbench 30). The other side surface is equipped with the placement box 33. The placement box 33 is the direct support component for the material tray 200, fixedly mounted on the mounting plate 32. It is made of lightweight, high-strength material (such as engineering plastic or thin steel plate) and has a hollow structure. The outer surface of the placement box 33 is a flat surface for placing the material tray 200. The bottom surface of the placement box 33 also has a hollow section to allow the central rotating shaft 31 to pass through and mate with the central hole of the material tray 200. The slidable central rotating shaft 31 is an adjustable positioning component for the material tray 200, made of a metal round shaft with a diameter that matches the inner diameter of the central hole of the material tray 200. The end of the rotating shaft near the mounting plate 32 is provided with a sliding seat adapted to the sliding guide structure of the mounting plate 32, allowing the central rotating shaft 31 to slide radially along the mounting plate 32, thereby adjusting the axial position and adapting to different sized trays. The end of the central rotating shaft 31 away from the mounting plate 32 can be provided with a locking structure to position the tray 200 and prevent the tray 200 from detaching from the central rotating shaft 31 without external force.

[0038] Furthermore, the tray 200 tilting device also includes a fourth motor 80 and a fourth transmission assembly 81. The fourth transmission assembly 81 is connected to the fourth motor 80 and the central rotating shaft 31. The fourth motor 80 is used to drive the central rotating shaft 31 to move in a straight line.

[0039] Specifically, in this embodiment, the mounting plate 32 is provided with a straight-shaped opening, and the fourth motor 80 is installed at one end of the opening and fixed to the mounting plate 32. The fourth transmission assembly 81 is connected to the mounting plate 32, and can be implemented by a slide rail, a slider, and a lead screw structure to realize the translation of the central rotating shaft 31. The mounting seat at the lower end of the central rotating shaft 31 is fixedly installed on the slider, and the mounting seat is connected to the lead screw transmission. The fourth motor 80 is started to drive the central rotating shaft 31 to slide along the lead screw.

[0040] Furthermore, the movable plate 20 is vertically arranged, and two spaced-apart pivot seats 21 are installed at the upper end of the movable plate 20. Each pivot seat 21 is provided with a rotating shaft. A connecting plate 321 is fixedly installed at the position corresponding to the pivot seat 21 on the mounting plate 32. The connecting plate 321 is fixedly connected to the rotating shaft. The third transmission component 71 is connected to the third motor 70 and the rotating shaft respectively. The third motor 70 is used to drive the rotating shaft, the connecting plate 321 and the mounting plate 32 to rotate, so as to rotate the worktable 30.

[0041] Specifically, two pivot seats 21 are fixed at intervals to the upper end of the movable plate 20. They are made of the same high-strength metal material as the movable plate 20 (such as aluminum alloy or steel plate), and their thickness must ensure support rigidity to prevent bending deformation during rotation. The spacing between the two pivot seats 21 is adapted to the width of the mounting plate 32 to ensure precise alignment of the connecting plates 321 on both sides of the mounting plate 32. Each pivot seat 21 has a pivot shaft mounting hole, into which a high-precision bearing (such as a deep groove ball bearing) is embedded to adapt to the pivot shaft and reduce frictional resistance during rotation. The pivot shaft is a cylindrical metal shaft, with two shafts in total, each installed in the bearing hole of one of the two pivot seats 21. One end of the pivot shaft extends to the outside of the pivot seat 21 (for connecting the fifth transmission component 54), and the other end extends into the pivot seat 21 (for connecting the connecting plate 321). There are two connecting plates 321, each fixed to one side of the mounting plate 32, corresponding to the pivot seats 21 one-to-one. Their thickness must meet the connection strength requirements to prevent breakage under stress. One end of the connecting plate 321 is rigidly connected to the side of the mounting plate 32; the other end is provided with a shaft hole adapted to the rotating shaft, and is fixed to the inner end of the rotating shaft by key connection or tight fit, so that the rotating shaft can directly drive the connecting plate 321 and the mounting plate 32 to rotate synchronously. The third transmission assembly 71 is used to connect the third motor 70 to the rotating shaft, and transmit the rotational power of the motor to the rotating shaft. Specifically, it can be implemented by using a synchronous belt + synchronous pulley, or by using a gear set structure. Furthermore, the material head fixing assembly 50 includes a fixing base 51, a bracket 52, a fifth motor 53, a fifth transmission assembly 54, and a cover plate 55. The fixing base 51 is fixedly installed on the mounting plate 32, and the bracket 52 is installed on the fixing base 51. The fifth transmission assembly 54 is connected to the cover plate 55 and the fifth motor 53 respectively, and is used to drive the cover plate 55 to rotate. The bracket 52 has a track groove 524, which is used to clamp the material head of the material belt 201. The cover plate 55 is placed on the track groove 524 to cover the upper part of the track groove 524. The bracket 52 includes a first plate 521, a second plate 522, and a third plate 523. The first plate 521 and the third plate 523 are arranged opposite to each other. The track groove 524 is located at the upper end of the first plate 521 and the third plate 523. The first plate 521 is fixedly installed on the fixing base 51, the second plate 522 is fixedly connected to the lower end of the first plate 521, and the third plate 523 is movable relative to the first plate 521.

[0042] Specifically, the fixing base 51 can be made of metal (such as aluminum alloy) and is rigidly connected to the surface of the mounting plate 32 by bolts. The connection position is close to the output end of the material strip 201 of the placement box 33, ensuring that the material strip 201 can naturally extend to the area of ​​the bracket 52. The bracket 52 is the core structure for clamping the material head and connecting the components. It consists of three metal plates: the first plate 521, the second plate 522, and the third plate 523. The overall structure is a "U" shaped frame and has a built-in track groove 524 for clamping the material head. The first plate 521 is a vertical plate, which is fixed to the side of the fixing base 51 by bolts. The plate surface is flat and extends along the conveying direction of the material strip 201. It is the main load-bearing plate of the bracket 52. The upper inner side of the first plate 521 has one side wall of the track groove 524. The second plate 522 is a horizontal plate, which is fixedly connected to the lower end of the first plate 521 to form an "L" shaped support structure. One end of the second plate 522 is welded or bolted to the first plate 521, and the other end extends towards the third plate 523. The third plate 523 is a movable vertical plate, positioned opposite the first plate 521. Their upper ends together form a track groove 524 (the upper wall of the first plate 521 and the inner side of the upper end of the third plate 523 form a groove), with the groove width adapted to the width of the material head. The third plate 523 is movable relative to the first plate 521, thereby adjusting the width of the track groove 524 to accommodate different sizes of material strips 201. The fifth motor 53 and the fifth transmission assembly 54 serve as the power source and transmission medium for the rotation of the cover plate 55. The fifth motor 53 can be a miniature stepper motor, compact in size (fitting the internal space of the bracket), with moderate output torque, and capable of forward and reverse rotation. It is fixed to the mounting base 51. The motor can be equipped with an angle sensor to provide real-time feedback on the rotation angle, ensuring precise closing or opening of the cover plate 55. When the cover plate 55 is opened, the material strip 201 portion of the material tray 200 is placed into the track groove 524. Subsequently, the fifth motor 53 drives the cover plate 55 to rotate, so as to cover the material head of the material strip 201 in the track groove 524. The fifth transmission assembly 54 can be a micro gear set, used to connect the fifth motor 53 and the cover plate 55.

[0043] like Figure 9 and Figure 10 As shown, the material head fixing assembly 50 also includes a pressure roller 56, a seat 57, a sliding block 58, and an elastic element 59; a sliding cavity 571 is formed inside the seat 57, and the sliding block 58 is slidably disposed in the sliding cavity 571; the elastic element 59 is disposed in the sliding cavity 571 to apply downward pressure to the sliding block 58; the pressure roller 56 is connected to the sliding block 58 and is used to press down the material strip 201 below the cover plate 55; the cover plate 55 has a through opening 551 at the position corresponding to the pressure roller 56 for the pressure roller 56 to slide.

[0044] Specifically, the seat 57 serves as the load-bearing foundation of the clamping structure. It is made of metal (such as aluminum alloy) and is cylindrical or block-shaped, fixed to the upper surface of the cover plate 55 by bolts. A sliding cavity 571 is formed vertically inside the seat 57. The cross-sectional shape of the sliding cavity 571 is adapted to the sliding block 58 (e.g., rectangular or circular), ensuring that the sliding block 58 can only slide vertically. The seat 57 is inverted and rests on the cover plate 55. The sliding block 58 is an intermediate component that transmits elastic pressure. It is made of metal or high-strength engineering plastic and is adapted to the size of the sliding cavity 571 of the seat 57, allowing it to slide freely up and down along the cavity. The upper surface of the sliding block 58 has a positioning groove for accommodating part of the elastic element 59, ensuring that the pressure of the elastic element 59 is accurately transmitted to the sliding block 58. The elastic element 59 is the core component providing the clamping force. It is typically a compression spring (or elastic rubber column), located within the sliding cavity 571 of the seat 57 and above the sliding block 58. The upper end of the elastic element 59 abuts against the top wall of the seat 57, and the lower end is embedded in the positioning groove of the sliding block 58. In its natural state, it is in a pre-compressed state and can continuously apply downward elastic pressure to the sliding block 58. The pressure roller 56 is a pressing component that directly contacts the material belt 201. The pressure roller 56 is sleeved on the mounting shaft at the lower end of the sliding block 58 through a bearing and can rotate freely, reducing the frictional resistance of the material belt 201 during conveying and avoiding wear of the material belt 201 due to sliding friction. The diameter and thickness of the pressure roller 56 must be adapted to the size of the through opening 551 on the cover plate 55. The through opening 551 is the movable channel of the pressure roller 56, which is opened at the position corresponding to the cover plate 55 and the pressure roller 56. It is elongated (extending along the conveying direction of the material belt 201), with a length slightly larger than the diameter of the pressure roller 56 and a width slightly larger than the thickness of the pressure roller 56, to ensure that the pressure roller 56 can pass through the cover plate 55 and slide freely up and down along the through opening 551. This application uses elastic force to press the material strip 201 into the track groove 524, ensuring that the material strip 201 is stably fixed.

[0045] The material head fixing assembly 50 also includes a sixth motor 90 and a mounting block 91. The sixth motor 90 is fixedly mounted on the fixing base 51. One end of the mounting block 91 is fixedly connected to the lower end of the third plate 523, and the other end of the mounting block 91 is connected to the rotating shaft of the sixth motor 90. A slide rail is provided at the lower end of the second plate 522, and the mounting block 91 has a slider adapted to the slide rail. The rotating shaft of the sixth motor 90 rotates, thereby driving the mounting block 91 and the third plate 523 to move along the slide rail, thereby adjusting the distance between the third plate 523 and the second plate 522, and thus adjusting the width of the track groove 524 at the upper end of the third plate 523 and the second plate 522 to accommodate material strips 201 of different widths.

[0046] Specifically, the sixth motor 90 serves as the power source for the movement of the third plate 523. It is a miniature servo motor (or stepper motor) with a compact size (fitting the space between the fixed base 51 and the second plate 522), moderate output torque, and controllable speed. The sixth motor is fixed to the side of the fixed base 51 (near the second plate 522), with its shaft positioned along the width of the track groove 524 (aligned with the movement direction of the third plate 523). It also supports forward and reverse rotation control, meeting the dual requirements of reducing and expanding the width of the track groove 524. The mounting block 91 is a transmission transition component connecting the sixth motor 90 and the third plate 523. It can be made of metal (such as aluminum alloy) and has an L-shaped or block-like structure. One end of the mounting block 91 is rigidly connected to the lower end of the third plate 523 via bolts, while the other end has a transmission interface adapted to the shaft of the sixth motor 90. The motor shaft is a threaded shaft, and the mounting block 91 has a corresponding internal threaded hole (forming a lead screw and nut fit). The slide rail below the second plate 522 serves as a guide for the movement of the third plate 523. It is fixed to the lower surface of the second plate 522 (extending along the width direction of the track groove 524) and employs a linear slide rail or groove structure. It is adapted to the slider on the mounting block 91, with the slider embedded in the slide rail to form a "slide rail-slider" sliding pair, restricting the third plate 523 to move only along the width direction of the track groove 524 and preventing lateral deviation.

[0047] The material head fixing assembly 50 also includes a seventh motor 92, a ratchet 93, and a sensor 94. The seventh motor 92 is fixedly mounted on the mounting base, and the shaft of the seventh motor 92 is connected to the ratchet 93 for transmission. The sensor 94 is mounted on the cover plate 55 and passes through the cover plate 55 to face the track groove 524, for detecting whether there is material belt 201 in the track groove 524. The ratchet 93 is rotatably mounted on the first plate 521, for driving the material belt 201 in the track groove 524 to move along the track groove 524.

[0048] Specifically, the seventh motor 92 is the power source for the rotation of the ratchet 93, and a micro stepper motor can be selected. The seventh motor 92 is located outside the first plate 521, and the motor shaft is connected to the rotating shaft of the ratchet 93 through a coupling. The transmission direction is the same as the rotation direction of the ratchet 93. The ratchet 93 is the driving component for conveying the material belt 201. It is made of metal (such as stainless steel), and several ratchet teeth are evenly distributed on the edge of the wheel (the number of ratchet teeth is designed according to the positioning port requirements on the material belt 201). The ratchet 93 is installed on the inner side of the first plate 521 (near the track groove 524) through the rotating shaft, and the wheel body extends into the track groove 524 (the insertion depth does not exceed 1 / 3 of the width of the track groove 524 to avoid interference with the third plate 523). The sensor 94 is a sensing component for detecting whether there is material belt 201 in the track groove 524. The sensor 94 is fixed on the cover plate 55, and the sensing head passes through the reserved hole on the cover plate 55, facing vertically towards the bottom surface of the track groove 524.
