[0002] This disclosure claims priority to Chinese Patent Application No. 202411992691.8, filed with the Chinese Patent Office on December 31, 2024, entitled “SMT Fully Automated Unmanned Material Handling System”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of SMT technology, and more specifically, to a fully automated unmanned material handling and feeding system for SMT. Background Technology

[0004] In recent years, the SMT (Surface Mount Technology) industry has developed rapidly in China. With the continuous increase in labor costs and the market's increasingly higher requirements for quality, factories are gradually replacing manual labor with automated equipment in the production process, and unmanned workshops will appear in the near future. With the gradual maturity of intelligent equipment technology, the current SMT automatic tape feeding equipment will move towards reducing labor costs. In order to meet the demand for improved quality and production efficiency, fully automatic unmanned SMT feeding equipment (automatic measurement and error prevention + feeding + automatic unloading) has emerged.

[0005] The current material receiving equipment on the market requires operators to place the new material tray on the left side onto the left receiving mechanism, trim excess material ends, and scan barcodes. Simultaneously, the operator must remove the nearly empty old material tray from the feeder on the right side of the pick-and-place machine, repeating the process for the left tray. Then, the material ends of both tapes are placed into the tape inlets on either side of the receiving machine before the receiving equipment can complete the receiving operation. This operational process requires operators to have relevant professional knowledge, raising the entry barrier for workers using the equipment, and significantly limiting work efficiency due to human factors.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0068] In the description of this disclosure, it should be noted that if terms such as “center,” “upper,” “lower,” “left,” “right,” “vertical,” “horizontal,” “inner,” and “outer” appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

[0069] Furthermore, the terms "first," "second," and "third" are configured only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0070] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0071] It should be noted that, where there is no conflict, the features in the embodiments of this disclosure can be combined with each other.

[0072] This disclosure provides a fully automatic unmanned material handling and feeding system for SMT, as shown in Figures 1 and 2. The system includes a material handling unit 1, a secondary telescopic material receiving unit 2, a conveyor belt unit 3, a gripping unit 4, an empty material tray recycling unit 5, an old material tray storage unit 6, and a material storage box unit 7.

[0073] The material receiving unit 1 is configured to discharge new material trays of different sizes to the secondary telescopic receiving unit 2 according to the process progress.

[0074] The secondary telescopic receiving unit 2 is located below the material taking unit 1 and is configured to adjust its width according to the size of the new material tray at the discharge station so as to accurately receive the new material tray; it is also configured to connect the material strip of the new material tray to the receiving unit 3 at the receiving station.

[0075] The receiving unit 3 is located at the receiving station and below the secondary telescopic receiving unit 2, and is configured to receive the material strips of the new material tray and the material heads of the old material tray.

[0076] The gripping unit 4 is configured to connect the material head of the old material tray stored in the old material tray storage unit 6 to the tape receiving unit 3; it is also configured to put the new material tray after the material is rolled into the old material tray storage unit 6, and to put the old material tray after the material is rolled into the empty material tray recycling unit 5.

[0077] The empty material tray recycling unit 5 is configured to store empty material trays;

[0078] The used material storage unit 6 is configured to store used material trays;

[0079] The storage bin unit 7 is configured to collect the remaining material from the old material tray and, after the tape connection is completed, roll the remaining material from the old material tray into the new material tray.

[0080] Optionally, the system further includes a fixed support 8; the fixed support 8 is configured to support the material receiving unit 1, the secondary telescopic receiving unit 2, the receiving belt unit 3, the gripping unit 4, the empty material tray recycling unit 5, the old material tray storage unit 6, and the storage box unit 7.

[0081] Optionally, the system further includes a moving unit 9, which is disposed at the bottom of the fixed bracket 8 and configured to drive the entire system to move.

[0082] In some implementations, the mobile unit 9 includes a transport trolley 91 and a trolley ground rail 92. The trolley ground rail 92 is set on the ground according to the needs of the travel trajectory. The transport trolley 91 is set in cooperation with the trolley ground rail 92 and is located at the bottom of the fixed bracket 8. In this way, the material receiving needs of the production line or batch placement machine equipment can be met at the same time, improving the responsiveness and mobility of the equipment.

[0083] This disclosure significantly reduces the proportion of manual operation through a fully automated material picking, receiving, and loading process, thereby greatly improving production efficiency; it also reduces the possibility of human error, such as repeated material receiving caused by picking the wrong material belt, further improving the stability and reliability of the production line; and through precise docking, it also reduces damage and waste of material belts during the receiving process, further reducing production costs.

[0084] As shown in Figures 3 and 4, the material handling unit 1 includes a hopper lateral moving mechanism 11 and a robot arm 12; the robot arm 12 is located on one side of the hopper lateral moving mechanism 11.

[0085] Specifically, the hopper lateral movement mechanism 11 includes a lateral movement drive mechanism 111, a fixed component 112, and a sliding component 113; the sliding component 113 is slidably disposed on the fixed component 112 and configured to carry the hopper 114; the lateral movement drive mechanism 111 is disposed on one side of the fixed component 112 and connected to the sliding component 113, and configured to drive the sliding component 113 to reciprocate along a first direction.

[0086] The material handling unit 1, through the cooperation of the transverse drive mechanism 111, the sliding component 113, and the fixed component 112, enables the hopper 114 to move along the first direction, so that the position of the hopper 114 can be flexibly adjusted to meet the different requirements of different production lines or process steps for material position, thereby improving the flexibility and adaptability of the production line.

[0087] Optionally, the fixing component 112 consists of at least two fixing members 1121 that are respectively matched with the hopper 114.

[0088] Specifically, since the hopper 114 can be of different sizes, each hopper 114 is matched with the corresponding fixing part 1121, which makes it easy for the material in the hopper 114 to be discharged by gravity natural falling method and directly discharged from the gap of the fixing part 1121.

[0089] Each of the fixing members 1121 is matched with the corresponding hopper 114 along the length of the second direction perpendicular to the first direction, and is configured to discharge material by gravity natural falling in cooperation with the corresponding hopper 114.

[0090] In other words, the width or longitudinal length of each of the fixing members 1121 matches the hopper 114, so that when the material in the hopper 114 is discharged by gravity natural discharge, it can be directly discharged from the gap in the width or longitudinal length of the fixing member 1121.

[0091] Optionally, at least two of the fixing members 1121 are connected sequentially along the second direction, and slide rails 11211 are provided on the edges of the fixing members 1121 on both sides of the second direction; the slide rails 11211 are configured to cooperate with the sliding assembly 113.

[0092] Specifically, at least two fasteners 1121 are connected sequentially along the second direction to form an integral fastening structure. Slide rails 11211 are provided on the edges of the fastening components 112 located on both sides of the second direction. These slide rails 11211 are configured to cooperate with the sliding components 113, so that the sliding components 113 can slide smoothly on the fastening components 112.

[0093] Of course, multiple slide rails 11211 can also be set parallel to each other along the second direction according to the size of the fixed component 112 and the sliding component 113, so that the sliding component 113 can slide smoothly on the fixed component 112.

[0094] Optionally, the hopper 114 includes a first hopper 1141 and a second hopper 1142, wherein the size of the first hopper 1141 is larger than the size of the second hopper 1142.

[0095] The first hopper 1141 and the second hopper 1142 are of different sizes to accommodate different materials.

[0096] For example, the first hopper 1141 can hold a 13-inch tray, and the second hopper 1142 can hold a 7-inch tray.

[0097] The first hopper 1141 and the second hopper 1142 are respectively matched with the length or width of the two fixing members 1121 along the second direction, so that when the material in the first hopper 1141 and the second hopper 1142 is discharged by gravity natural discharge, it can be directly discharged from the gap in the width or length of the fixing member 1121.

[0098] Optionally, the sliding assembly 113 includes a sliding frame 1131, which matches the size of all the fasteners 1121 and has a matching opening at the position corresponding to each fastener 1121.

[0099] The sliding frame 1131 is provided with sliders 11111 on both sides that cooperate with the slide rail 11211. In this way, the sliders 11111 ensure that the sliding frame 1131 can slide smoothly and accurately on the slide rail 11211.

[0100] The slider 11111 is fixed to the sliding frame 1131 to enhance the structural stability of the entire sliding assembly 113.

[0101] In some embodiments, the lateral drive mechanism 111 includes a first drive motor 1111 and a synchronous belt 1112. The first drive motor 1111 is disposed on one side of the fixed component 112, and the two sides of the synchronous belt 1112 are sleeved on synchronous pulleys. The first drive motor 1111 is connected to one of the synchronous pulleys, and the sliding component 113 is connected to the synchronous belt 1112 and configured to reciprocate along a first direction with the movement of the synchronous belt 1112.

[0102] Of course, the lateral drive mechanism 111 can also be implemented by a lead screw module or a gear and rack drive to achieve the linear motion of this disclosure.

[0103] After the transverse drive mechanism 111 is started, it drives the sliding component 113 to move along the fixed component 112 in the first direction. Since the sliding component 113 has a hopper 114, the hopper 114 is moved along the first direction. After it is moved to the corresponding position, the corresponding hopper 114 is opened by the robot arm 12. When the material in the hopper 114 is discharged by gravity, it can be discharged directly from the gap in the width or length of the fixed component 112, thereby completing the discharge.

[0104] As shown in Figures 5-10, the secondary telescopic receiving unit 2 includes a width adjustment and alignment mechanism 21, a material belt driving mechanism 22, and a third support component 24. The material belt driving mechanism 22 is disposed on the third support component 24 opposite to the width adjustment and alignment mechanism 21.

[0105] Specifically, the width adjustment and alignment mechanism 21 includes a first support component 211, a width adjustment drive component 212, and a strip alignment component 213. The strip alignment component 213 includes a first alignment member 2131 and a second alignment member 2132.

[0106] The first alignment member 2131 and the second alignment member 2132 are disposed opposite to each other on the first support assembly 211 and configured to abut against both sides of the material tray of the material strip to position the material strip; the width adjustment drive assembly 212 is disposed on the first support assembly 211 and is drivenly connected to at least one of the first alignment member 2131 and the second alignment member 2132.

[0107] The first alignment member 2131 is fixedly mounted on the first support component 211. The width adjustment drive component 212 is drivenly connected to the second alignment member 2132 and can drive the second alignment member 2132 to move closer to or further away from the first alignment member 2131.

[0108] When locating the material head, the material belt drive mechanism 22 is connected to the material belt drive located between the first alignment member 2131 and the second alignment member 2132. By driving the material belt on the material tray to rotate, the material head is located.

[0109] In some embodiments, the first alignment member 2131 is fixedly disposed on the first support component 211, and the width adjustment drive component 212 is drivenly connected to the second alignment member 2132 and can drive the second alignment member 2132 to move towards or away from the first alignment member 2131.

[0110] Thus, the first alignment member 2131 is a fixed alignment member, and the second alignment member 2132 is a movable alignment member. The spacing can be adjusted by driving the second alignment member 2132 to move.

[0111] In some embodiments, the width adjustment and alignment mechanism 21 includes a width adjustment guide assembly 214, which includes a width adjustment guide member 2141 and a width adjustment moving member 2142.

[0112] The width-adjusting guide 2141 is fixedly mounted on the first support assembly 211; the width-adjusting moving part 2142 is fixedly mounted on the second alignment part 2132 and slides in cooperation with the width-adjusting guide 2141.

[0113] The width-adjusting guide 2141 and the width-adjusting moving part 2142 work together to effectively limit the movement trajectory of the second alignment part 2132, thereby ensuring the stability of the spacing adjustment process and ensuring the spacing adjustment effect.

[0114] Specifically, the width-adjusting guide 2141 is configured as a guide rail, and the width-adjusting moving part 2142 is configured as a slider. The slider is connected to the second alignment part 2132 through a connector. To further ensure the stability of the movement, the number of sliders is set to multiple, and multiple sliders are connected to the second alignment part 2132.

[0115] In some embodiments, the first alignment member 2131 includes a first guide segment 21311 and a first connecting segment 21312 that are fixedly connected in sequence. The first guide segment 21311 is inclined relative to the line of symmetry between the first alignment member 2131 and the second alignment member 2132. Along the direction away from the first connecting segment 21312, the distance between the first guide segment 21311 and the second alignment member 2132 gradually increases; thus, it is convenient for the material belt to be fed.

[0116] In some embodiments, the second alignment member 2132 includes a second guide segment 21321 and a second connecting segment 21322 that are fixedly connected in sequence. The second guide segment 21321 is inclined relative to the line of symmetry between the first alignment member 2131 and the second alignment member 2132. Along the direction away from the second connecting segment 21322, the distance between the second guide segment 21321 and the first alignment member 2131 gradually increases.

[0117] The first guide section 21311 corresponds to the second guide section 21321, the first connecting section 21312 corresponds to the second connecting section 21322, and the first alignment member 2131 and the second alignment member 2132 are symmetrically arranged, so that the guide section forms an angle structure, and the material feeding effect is significant.

[0118] In some embodiments, the width adjustment drive assembly 212 adopts an electric drive mechanism, preferably a bidirectional lead screw motor. Further, the lead screw of the lead screw motor adopts a three-section structure, including a first threaded section, an intermittent connecting section and a second threaded section arranged in sequence. The first threaded section is connected to the motor, and the connecting member connected to the width adjustment moving member 2142 is provided with a threaded hole. The second threaded section passes through the threaded hole and is threadedly engaged with the threaded hole.

[0119] Thus, the rotation of the lead screw of the lead screw motor can drive the second alignment member 2132 to move.

[0120] In some embodiments, the belt drive mechanism 22 includes a second support component 222, a belt power component 221, and a rotating component 223.

[0121] The material belt power assembly 221 is fixedly mounted on the second support assembly 222. The output end of the material belt power assembly 221 is connected to the rotating component 223 and can drive the rotating component 223 to rotate. The rotating component 223 is provided with meshing teeth, which are configured to mesh with the opening of the material belt.

[0122] When locating the material head, when the first alignment member 2131 and the second alignment member 2132 abut against the two sides of the material tray, the meshing teeth engage with the opening of the material belt. At this time, the material belt power assembly 221 provides power for the movement of the material belt, and the rotating member 223 can stably transmit the rotational power output by the material belt power assembly 221 to the material belt.

[0123] Specifically, the conveyor belt power assembly 221 uses a rotary motor, and the rotating component 223 is set as a rotary gear.

[0124] In some embodiments, the tape drive mechanism 22 includes a position detection component 224, which includes an optical fiber head disposed between a first alignment member 2131 and a second alignment member 2132. During the tape rotation, when the tape head moves to the optical fiber head, the optical fiber head can detect its relative position, thereby controlling the tape drive component 221 to stop.

[0125] In some embodiments, the secondary telescopic receiving unit 2 includes a strip clamping mechanism 23, and at least one of the first support component 211 and the second support component 222 is connected to the strip clamping mechanism 23.

[0126] In this way, the distance between the first support component 211 and the second support component 222 can be adjusted.

[0127] In some embodiments, the material strip clamping mechanism 23 includes a first clamping member 231 and a second clamping member 232. The first clamping member 231 is fixedly disposed on the first support component 211; the second clamping member 232 is fixedly disposed on the second support component 222 and is positioned opposite to the first clamping member 231.

[0128] When locating the material head, the first clamping member 231 and the second clamping member 232 clamp the material tray of the material strip between the first alignment member 2131 and the second alignment member 2132 in the front-back direction, and the first alignment member 2131 and the second alignment member 2132 abut against the two sides of the material tray of the material strip in the left-right direction.

[0129] During the process, the first clamping member 231 and the second clamping member 232 stably clamp the material tray of the material belt to avoid slippage and effectively ensure the material belt movement effect.

[0130] The first alignment member 2131 and the second alignment member 2132 effectively limit the position of the material tray, prevent deviation, and ensure that the material strip is aligned with the rotating member 223.

[0131] In some embodiments, the material strip clamping mechanism 23 further includes a buffer guide 233, a buffer moving member 234, and an elastic member 235. The buffer guide 233 is configured as a guide rail, the buffer moving member 234 is configured as a slider, and the elastic member 235 is a spring.

[0132] The buffer guide 233 is fixedly mounted on the second support assembly 222; the buffer moving part 234 is fixedly mounted on the second clamping part 232 and slides in cooperation with the buffer guide 233; the two ends of the elastic part 235 are respectively connected to the second clamping part 232 and the second support assembly 222.

[0133] When the first clamping member 231 and the second clamping member 232 clamp the material tray of the material strip, the elastic member 235 deforms.

[0134] The elastic element 235 has a buffering function, which makes the first clamping element 231 and the second clamping element 232 firmly clamp the material tray. On the other hand, it has a return function. When the material head is found, the clamping force is eliminated, and the elastic element 235 provides elastic restoring force to return the second clamping element 232 to its original position.

[0135] Specifically, the elastic element 235 is a tension spring, which undergoes tensile deformation when the first clamping element 231 and the second clamping element 232 clamp the material tray; in practical applications, a compression spring can also be used, which undergoes compressive deformation when clamping the material tray.

[0136] In some embodiments, the material strip clamping mechanism 23 includes a first clamping moving member 238, a clamping guide member 237, and a first clamping driving assembly 236. The first clamping moving member 238 is fixedly disposed on the first support assembly 211 and slides in cooperation with the clamping guide member 237. The first clamping driving assembly 236 is drivenly connected to the first support assembly 211 and can drive the first support assembly 211 and the first clamping moving member 238 to move synchronously along the clamping guide member 237. In this way, the width adjustment and alignment mechanism 21 can move independently.

[0137] Specifically, the first clamping drive assembly 236 adopts a lead screw drive mechanism and is located on the lower side of the third support assembly 24. The clamping guide 237 is a slide rail and is located on the upper side of the third support assembly 24. The first clamping moving part 238 is a moving block and is slidably disposed on the slide rail. The third support assembly 24 is provided with a guide groove parallel to the clamping guide 237. The moving end of the first clamping drive assembly 236 is provided with a sliding adapter block. The sliding adapter block passes through the guide groove and is fixedly connected to the first support assembly 211. The sliding adapter block is slidably engaged with the guide groove.

[0138] In some embodiments, the material strip clamping mechanism 23 includes a second clamping moving member 2311 and a second clamping driving assembly 2312. The second clamping moving member 2311 is fixedly disposed on the second support assembly 222 and slidably engaged with the clamping guide 237. The second clamping driving assembly 2312 is drivenly connected to the second support assembly 222 and can drive the second support assembly 222 and the second clamping moving member 2311 to move synchronously along the clamping guide 237. In this way, the material strip driving mechanism 732 can move independently.

[0139] The second clamping moving part 2311 has a similar structure to the first clamping moving part 238, and the second clamping driving assembly 2312 has a similar structure to the first clamping driving assembly 236.

[0140] The working process of the secondary telescopic receiving unit 2 is as follows:

[0141] First, the first clamping drive assembly 236 and the second clamping drive assembly 2312 are activated, causing the width adjustment and alignment mechanism 21 and the material belt drive mechanism 22 to move relative to each other. The second clamping member 232 pushes the material tray between the first alignment member 2131 and the second alignment member 2132, and cooperates with the first clamping member 231 to clamp the material tray. Then, the width adjustment drive assembly 212 is activated, driving the second alignment member 2132 to move closer to the first alignment member 2131, so that the left and right sides of the material tray abut against the first alignment member 2131 and the second alignment member 2132, achieving alignment with the rotating member 223. At this time, the meshing teeth of the rotating member 223 engage with the opening of the material belt, and the rotating member 223 rotates, causing the material belt to move relative to its material tray, thereby finding the material head.

[0142] As shown in Figures 11-17, the storage bin unit 7 includes a drive mechanism 73, a moving part 72, a bin body 71 with a material conveyor belt inlet 713, a rotating wheel mechanism 76, a wheel mechanism 75, and a clamping mechanism 74. The bin body 71 includes a fixed side wall 711 and a moving side wall 712, which are located on opposite sides of the material conveyor belt inlet 713. The drive mechanism 73 is drivenly connected to the moving part 72, and the moving part 72 is fixedly connected to the moving side wall 712. The drive mechanism 73 drives the moving part 72 to reciprocate, thereby driving the moving sidewall 712 to move in a direction close to or away from the fixed sidewall 711, thereby adjusting the width of the material belt inlet 713; the roller mechanism 76 and the wheel mechanism 75 are disposed at both ends of the material belt inlet 713 and configured to introduce the material belt into the box body 71; the clamping mechanism 74 is disposed above the box body 71, and the output end of the clamping mechanism 74 cooperates with the roller mechanism 76 and the wheel mechanism 75 to clamp the material belt.

[0143] The moving sidewall 712 is driven by the driving mechanism 73 to move in a direction close to or away from the fixed sidewall 711, thereby changing the distance between the fixed sidewall 711 and the moving sidewall 712. This makes the width of the material inlet 713 compatible with the required width of the material strip, and can buffer material strips of multiple widths, improving compatibility and adaptability.

[0144] In some embodiments, the moving part 72 includes a lead screw 721, a bearing 722, and a width-adjusting slider 723. The bearing 722 and the width-adjusting slider 723 are respectively fixed on the fixed sidewall 711 and the moving sidewall 712. One end of the lead screw 721 passes through the bearing 722 and is connected to the driving mechanism 73. The fixed end of the driving mechanism 73 is fixedly connected to the fixed sidewall 711. The other end of the lead screw 721 and the width-adjusting slider 723 form a ball screw pair. The driving mechanism 73 drives the lead screw 721 to rotate, thereby causing the width-adjusting slider 723 to translate along the lead screw 721, and then causing the moving sidewall 712 to move synchronously, so that the width of the material strip inlet 713 changes to adapt to the required width of the material strip to be stored.

[0145] The drive mechanism 73 includes a width-adjusting motor 731, a transmission belt 732, and a transmission wheel 733. There are multiple moving parts 72. The width-adjusting motor 731 drives all the moving parts 72 to move synchronously via the transmission belt 732 and the transmission wheel 733. Specifically, the multiple moving parts 72 are distributed along the edge of the housing body 71. Each moving part 72 has a transmission wheel 733 at one end of its lead screw 721. The transmission belt 732 is wound around all the transmission wheels 733. The power output shaft of the width-adjusting motor 731 is connected to one of the lead screws 721, thereby causing the width-adjusting sliders 723 on all the lead screws 721 to move synchronously. This, in turn, drives the edges of the fixed sidewall 711 and the moving sidewall 712 to move synchronously, ensuring equal width at each position.

[0146] In some embodiments, the rotary wheel mechanism 76 and the wheel mechanism 75 are disposed at both ends of the material belt inlet 713 and configured to introduce the material belt into the box body 71. The clamping mechanism 74 is disposed above the box body 71. The output end of the clamping mechanism 74 cooperates with the rotary wheel mechanism 76 and the wheel mechanism 75 to clamp the material belt. The free end of the material belt is clamped and fixed by the clamping mechanism 74 and the wheel mechanism 75. One end of the material belt connected to the material tray is clamped and fixed by the clamping mechanism 74 and the rotary wheel mechanism 76. During operation, a robotic arm is used to lay the material belt flat on the rotary wheel mechanism 76 and the wheel mechanism 75. The clamping mechanism 74 cooperates with the rotary wheel mechanism 76 and the wheel mechanism 75 to clamp the material belt. The rotary wheel mechanism 76 is rotated to make the material belt concave in the direction of the material belt inlet 713. As the rotary wheel mechanism 76 rotates continuously, the material belt in the material tray is continuously guided into the box body 71.

[0147] Specifically, the rotary wheel mechanism 76 includes a rotary wheel motor 761, a drive wheel 762, and a limiting wheel 763. The rotary wheel motor 761 is fixed on the fixed side wall 711, the drive wheel 762 is fixed on the power output shaft of the rotary wheel motor 761, and the limiting wheel 763 is fixed on the movable side wall 712 and coaxially aligned with the drive wheel 762. There is a gap between the drive wheel 762 and the limiting wheel 763. The movable side wall 712 is adjusted by the drive mechanism 73 and the moving part 72, thereby changing the gap between the drive wheel 762 and the limiting wheel 763 to match the required width of the feed strip, so that the feed strip overlaps the drive wheel 762 and the limiting wheel 763. As an optimization, the outer edge of the drive wheel 762 is evenly provided with multiple protrusions, which match the concave points on the feed strip. When the drive wheel 762 rotates, the feed strip is moved by the cooperation of the protrusions and concave points.

[0148] Furthermore, the wheel mechanism 75 includes a first wheel 751 and a second wheel 752. The first wheel 751 is fixed to the fixed sidewall 711, and the second wheel 752 is fixed to the movable sidewall 712 and coaxially aligned with the first wheel 751. There is a gap between the first wheel 751 and the second wheel 752. A frustum 753 is provided on the opposite side of the first wheel 751 and the second wheel 752. The frustum 753 is configured to receive the material belt and is adjustable by the drive mechanism 73 and the moving part 72. The movable sidewall 712 changes the distance between the first wheel 751 and the second wheel 752 to match the width of the material strip, so that the material strip rests on the truncated cone 753 and is clamped from both sides by the first wheel 751 and the second wheel 752. At the same time, the clamping mechanism 74 cooperates with the first wheel 751 and the second wheel 752 to clamp the free end of the material strip, so that the free end of the material strip is anchored, so that the material strip in the tray can continuously enter the box body 71 through the material strip inlet 713 under the drive of the rotating wheel mechanism 76.

[0149] Specifically, the clamping mechanism 74 includes a frame 741, a first fixing plate 742, a second fixing plate 743, a first clamping wheel 745, a second clamping wheel 746, and a pressure plate 747. The box body 71 and the first fixing plate 742 are fixed on the frame 741. The second fixing plate 743 is slidably connected to the first fixing plate 742 and is movable along the Y-axis. The pressure plate 747 is slidably connected to the second fixing plate 743 and is movable along the Z-axis. This configuration allows adjustment of the spatial position of the pressure plate 747 to align with the rotating wheel mechanism 76, the wheel mechanism 75, and the material belt inlet 713. The first clamping wheel 745 and the second clamping wheel 746 are respectively located at both ends of the pressure plate 747 and are respectively aligned with the rotating wheel mechanism 76 and the wheel mechanism 75 along the Z-axis. The disc mechanism 75 has the center of the pressure plate 747 aligned with the material inlet 713. In use, the robotic arm first moves the disc around the top of the rotating wheel mechanism 76 and the wheel mechanism 75, so that the material strip is laid flat on the rotating wheel mechanism 76 and the wheel mechanism 75. Then, the position of the clamping mechanism 74 is adjusted so that the clamping mechanism 74 moves and aligns with the top of the rotating wheel mechanism 76 and the wheel mechanism 75, so that the first clamping wheel 745 aligns with the rotating wheel mechanism 76 and the second clamping wheel 746 aligns with the wheel mechanism 75, thereby clamping the material strip. At this time, the bottom of the pressure plate 747 is aligned with the material inlet 713. Rotating the rotating wheel mechanism 76 prevents the material strip from bending upwards, ensuring that the material strip bends towards the material inlet 713, thereby continuously guiding it into the box body 71.

[0150] In some embodiments, the system further includes a first telescopic motor 748, a slide plate 749, and a first guide rail 7410. The first telescopic motor 748, slide plate 749, and first guide rail 7410 are configured to move the second fixed plate 743 along the Y-axis direction. Specifically, the first guide rail 7410 is disposed on the first fixed plate 742 along the Y-axis direction, the first telescopic motor 748 is disposed at one end of the first guide rail 7410, and the first guide rail 7410 is provided with a first slider 74101. The first slider 74101 is fixedly connected to the slide plate 749. One end of the slide plate 749 is connected to the output shaft of the first telescopic motor 748, and the other end of the slide plate 749 is perpendicularly connected to the second fixed plate 743. The first telescopic motor 748 pushes the slide plate 749 to move along the Y-axis direction, thereby driving the second fixed plate 743 to move, so that the pressure plate 747, the first clamping wheel 745, and the second clamping wheel 746 on the second fixed plate 743 are respectively aligned with the material belt inlet 713, the rotary wheel mechanism 76, and the wheel mechanism 75 in the Z-axis direction. It can be understood that the Y-axis direction is the direction of movement of the moving sidewall 712 relative to the fixed sidewall 711.

[0151] Furthermore, it also includes a second telescopic motor 7411, a connecting plate 7412, and a second guide rail 7413. The second telescopic motor 7411, connecting plate 7412, and second guide rail 7413 are configured to move the pressure plate 747 along the Z-axis direction. Specifically, the second guide rail 7413 is disposed on the second fixed plate 743 along the Z-axis direction, the second telescopic motor 7411 is disposed at the top of the second guide rail 7413, the second guide rail 7413 is provided with a second slider 74131, the second slider 74131 is fixedly connected to the pressure plate 747, and one end of the connecting plate 7412 is connected to the second fixed plate 7413. The output shaft of the telescopic motor 7411 is connected to the other end of the connecting plate 7412, which is connected to the pressure plate 747. The second telescopic motor 7411 pushes the connecting plate 7412 to move along the Z-axis, thereby moving the pressure plate 747. This causes the pressure plate 747, the first clamping wheel 745, and the second clamping wheel 746 to press the material strip. It is worth noting that the first clamping wheel 745 and the second clamping wheel 746 can be installed at both ends of the pressure plate 747 through a telescopic mechanism, so that the clamping degree between the first clamping wheel 745 and the second clamping wheel 746 and the rotating wheel mechanism 76 and the wheel disc mechanism 75 can be manually adjusted.

[0152] In this embodiment, a positioning mechanism 77 is also included. The positioning mechanism 77 is slidably connected to the frame 741 and is movable along the Z-axis. The positioning mechanism 77 is configured to position the material strip on the Y-axis so that the material strip can be aligned and laid flat on the rotary wheel mechanism 76 and the wheel mechanism 75.

[0153] Specifically, the positioning mechanism 77 includes a third telescopic motor 771, a positioning plate 772, a positioning seat 773, and a pad 774. The positioning seat 773 can be raised and lowered along the frame 741. A third guide rail 7731 is provided on the positioning seat 773. The third telescopic motor 771 is located at one end of the third guide rail 7731. A third slider 7732 is slidably connected to the third guide rail 7731. One end of the third slider 7732 is connected to the output shaft of the third telescopic motor 771, and the other end of the third slider 7732 is connected to the positioning plate 772. The positioning plate 772 is configured to adjust the alignment of the material belt with the rotary wheel mechanism 76 and the wheel mechanism 75. A pad 774 is disposed at one end of the box body 71. The pad 774 is aligned with the positioning seat 773 in the Z-axis direction. In use, the free end of the material strip passes between the pad 774 and the positioning seat 773 and extends above the rotary mechanism 76 and the wheel mechanism 75. The side of the material strip contacts the positioning plate 772. The third telescopic motor 771 pushes the positioning plate 772 to move, thereby driving the material strip to move along the third guide rail 7731 until the material strip is aligned with the rotary mechanism 76, the wheel mechanism 75 and the material strip inlet 713 in the X-axis direction. At this time, the positioning mechanism 77 is lowered so that the positioning seat 773 abuts against the pad 774, thereby fixing the material strip.

[0154] In this embodiment, the frame 741 is provided with a fourth guide rail 7411 in the vertical direction, the positioning seat 773 is slidably connected to the fourth guide rail 7411, and also includes a wheel mechanism 78 configured to lift the positioning mechanism 77, the wheel mechanism 78 being installed on one side of the fourth guide rail 7411.

[0155] The pulley mechanism 78 includes a second drive motor 781, a drive wheel 782, a driven wheel 783, and a belt 784. The drive wheel 782 and the driven wheel 783 are rotatably connected to the frame 741. The belt 784 is wound around the drive wheel 782 and the driven wheel 783. The output shaft of the second drive motor 781 is connected to the drive wheel 782. The positioning seat 773 is fixedly connected to the belt 784. The second drive motor 781 drives the belt 784 to rotate around the drive wheel 782 and the driven wheel 783, thereby driving the positioning seat 773 to rise and fall along the fourth guide rail 7411.

[0156] The robotic arm grasps the material tray, connecting the free end of the material strip to the equipment from the previous process. The robotic arm then guides the material strip through the positioning seat 773 and the pad 774. The positioning mechanism 77 adjusts the position of the material strip in the X-axis direction via the positioning plate 772, aligning the material strip with the rotary wheel mechanism 76, the wheel disc mechanism 75, and the material strip inlet 713. The positioning mechanism 77 is then lowered, clamping the material strip between the positioning seat 773 and the pad 774. The robotic arm extends and lays the material strip flat on the rotary wheel mechanism 76, the wheel disc mechanism 75, and the material strip inlet 713. The width-adjusting motor 731 drives the lead screw 721 to rotate, causing the moving sidewall 712 to translate, thus adjusting the width of the material strip inlet 713. The width of the material belt is adjusted, and then the pressure plate 747 is aligned with the material belt in the Z-axis direction by the first telescopic motor 748. The second telescopic motor 7411 adjusts the pressure plate 747 to descend, so that the first clamping wheel 745 and the second clamping wheel 746 press the material belt onto the rotating wheel mechanism 76 and the wheel mechanism 75. The rotating wheel motor 761 is started, driving the drive wheel 762 to rotate, so that the material belt clamped between the drive wheel 762 and the first clamping wheel 745 moves towards the wheel mechanism 75. The pressure plate 747 blocks the material belt from above, so that the material belt bends and extends downward, that is, towards the material belt inlet 713, thereby gradually guiding it into the box body 71.

[0157] As shown in Figures 18-27, the gripping unit 4 includes a material strip extraction mechanism 41, a lifting mechanism 42, and a rotating mechanism 43;

[0158] The material strip extraction mechanism 41 includes a material threading rod mechanism 411, a workpiece support extraction mechanism 412, and a fourth support assembly 413. The material threading rod mechanism 411 and the workpiece support extraction mechanism 412 are respectively disposed on the fourth support assembly 413.

[0159] The lifting mechanism 42 includes a lifting guide 422, a lifting moving part 423, and a lifting drive assembly 421.

[0160] The lifting guide 422 is arranged vertically; the lifting moving part 423 is movably arranged on the lifting guide 422; the fourth support component 413 is fixedly arranged on the lifting moving part 423; the lifting drive component 421 is connected to the lifting moving part 423 and can drive the lifting moving part 423 and the material strip extraction mechanism 41 to move synchronously along the lifting guide 422.

[0161] The rotating mechanism 43 is mounted on the lifting guide 422.

[0162] During operation, the workpiece tray extraction mechanism 412 first extracts the workpiece tray configured to hold the material tray, and then the material feeding rod mechanism 411 extracts the material tray.

[0163] The material strip extraction mechanism 41 further includes a horizontal guide assembly 414, which includes a horizontal guide member 4141 and a horizontal moving member 4142. The horizontal guide member 4141 is configured as a guide rail, and the horizontal moving member 4142 is configured as a slider. The horizontal guide member 4141 is fixedly mounted on the fourth support assembly 413. The horizontal moving member 4142 is fixedly mounted on the fifth support assembly 4111 and slides in cooperation with the horizontal guide member 4141.

[0164] The horizontal guide 4141 and the horizontal moving part 4142 cooperate with each other to effectively limit the movement trajectory of the fifth support component 4111 relative to the fourth support component 413.

[0165] In some embodiments, the workpiece holder extraction mechanism 412 includes a push-pull claw 4121 and a push-pull drive assembly 4122. The push-pull drive assembly 4122 is preferably a lead screw motor, and its lead screw nut is fixedly mounted on the fifth support assembly 4111. When the lead screw of the push-pull drive assembly 4122 rotates, the lead screw nut and the fifth support assembly 4111 move along the lead screw axis.

[0166] The push-pull claw 4121 is fixedly mounted on the fifth support component 4111; the push-pull drive component 4122 is fixedly mounted on the fourth support component 413.

[0167] When the workpiece tray is removed, the push-pull drive assembly 4122 drives the fifth support assembly 4111 to move, and the push-pull claw 4121 moves synchronously. After the push-pull claw 4121 hooks the workpiece tray, the push-pull drive assembly 4122 drives the fifth support assembly 4111 to move in the opposite direction, and the push-pull claw 4121 moves synchronously in the opposite direction, thereby hooking the workpiece tray to move.

[0168] The workpiece tray extraction mechanism 412 and the material threading rod mechanism 411 work together to achieve a significant material tray extraction effect.

[0169] Optionally, the material strip extraction mechanism 41 further includes a push detection component configured to detect the moving position of the push-pull claw 4121. The push detection component includes a photoelectric switch fixedly mounted on the fourth support component 413 and a sensing sheet fixedly mounted on the fifth support component 4111.

[0170] The material feeding rod mechanism 411 includes a fifth support component 4111, an expansion shaft drive component 4112, an expansion shaft body 4113, and an expansion shaft pull rod 4114.

[0171] The expansion shaft drive assembly 4112, the expansion shaft body 4113, and the expansion shaft tie rod 4114 are all mounted on the fifth support assembly 4111. The expansion shaft body 4113 is sleeved on the expansion shaft tie rod 4114. The expansion shaft tie rod 4114 can move along the axial direction of the expansion shaft body 4113. The expansion shaft drive assembly 4112 is driven to connect with the expansion shaft tie rod 4114. The expansion shaft body 4113 has an open state and a closed state.

[0172] When not in operation, the expansion shaft body 4113 is in a closed state.

[0173] During operation, the expansion shaft body 4113 is inserted into the center hole of the material tray. The expansion shaft drive assembly 4112 drives the expansion shaft tie rod 4114 to move in the positive direction along the axial direction of the expansion shaft body 4113, causing the expansion shaft body 4113 to open, thereby tightening the center hole of the material tray and thus fixing the material tray.

[0174] After the material tray is transferred, the expansion shaft drive assembly 4112 drives the expansion shaft tie rod 4114 to move in the opposite direction along the axial direction of the expansion shaft body 4113. At this time, the expansion shaft body 4113 returns from the open state to the closed state, thereby releasing the material tray.

[0175] During the process, the expansion shaft drive assembly 4112, the expansion shaft body 4113, and the expansion shaft tie rod 4114 cooperate with each other to extract and transfer the material tray by inserting into and tightening the center hole of the material tray. This not only has a significant transfer effect but also can adapt to material trays of different width specifications, making it widely applicable and highly compatible, which is beneficial to the overall compatibility development of the receiving equipment.

[0176] The expansion shaft body 4113 includes an integrally formed connecting section and a tightening section, and the expansion shaft tie rod 4114 includes a tie rod body and a tie rod head 41141 integrally formed at the end of the tie rod body.

[0177] The connecting section is rotatably mounted on the fifth support component 4111. The tensioning section includes unit tensioning plates 41131 evenly distributed along the circumference. The unit tensioning plates 41131 are elastic. The pull rod body is driven to connect with the expansion shaft drive component 4112.

[0178] In the initial state, the pull rod head 41141 is located outside the tensioning section, and all unit tensioning plates 41131 are in the closed state.

[0179] During operation, the expansion shaft pull rod 4114 moves in the positive direction along the axial direction of the expansion shaft body 4113 under the drive of the expansion shaft drive assembly 4112. The pull rod head 41141 moves into the tensioning section and pushes the unit tensioning plate 41131 to move away from the axis of the expansion shaft body 4113, thereby putting the expansion shaft body 4113 in an open state.

[0180] After the material tray is transferred, the expansion shaft drive assembly 4112 drives the expansion shaft pull rod 4114 to move in the opposite direction, and the pull rod head 41141 moves to the outside of the expansion section. At this time, the unit expansion plate 41131 returns to its initial state under the action of its own elasticity.

[0181] The pull rod head 41141 is provided with a conical surface, so that even if the diameter of the center hole of the material tray is inconsistent, the pull rod head 41141 can still tighten the material tray, further improving its applicability.

[0182] The expansion shaft drive assembly 4112 adopts a pneumatic drive assembly, an electric drive assembly or a hydraulic drive assembly. Preferably, the expansion shaft drive assembly 4112 adopts a lead screw motor, specifically a bidirectional lead screw motor, whose extension end is connected to the expansion shaft tie rod 4114.

[0183] In some embodiments, the feed rod mechanism 411 includes a winding assembly 4115, which includes a winding drive assembly 41151 and a rotating member 41152.

[0184] The roll drive assembly 41151 is fixed on the fifth support assembly 4111 and connected to the rotating component 41152, which can drive the rotating component 41152 to rotate. The rotating component 41152 is fixedly sleeved on the outside of the expansion shaft body 4113 and rotates synchronously with the expansion shaft body 4113.

[0185] During the winding process, the winding drive assembly 41151 drives the rotating component 41152 to rotate, and the expansion shaft body 4113 rotates synchronously. At this time, since the expansion shaft body 4113 tightens the material tray, the material tray rotates synchronously, thereby realizing the winding function.

[0186] Preferably, the roll drive assembly 41151 is a rotary motor with an output gear at its output end, and the rotating part 41152 is a rotary gear. The rotary gear meshes with the output gear, and the gear transmission structure is simple and the transmission process is stable.

[0187] In some embodiments, the roll assembly 4115 includes a damper 41153, which is connected to a transmission gear. The rotating gear meshes with the transmission gear. The damper 41153 is a permanent magnet damper, which is frictionless, wear-free, pollution-free, has a large damping range, and an adjustable damping coefficient.

[0188] In some embodiments, the expansion shaft tie rod 4114 is connected to the output end of the expansion shaft drive assembly 4112 via a connector 4116, and the feed rod mechanism 411 includes an anti-deviation limiting member 4117, which slides along the axial direction of the expansion shaft tie rod 4114 with the connector 4116.

[0189] Thus, the connector 4116 serves two purposes: firstly, it provides a transmission connection, effectively transmitting the extension and retraction of the expansion shaft drive assembly 4112 to the expansion shaft tie rod 4114; secondly, it works in conjunction with the anti-deviation limiting component 4117 to limit the movement trajectory of the expansion shaft tie rod 4114, preventing it from deviating during movement.

[0190] Specifically, the anti-deviation limiting component 4117 is configured as a limiting rod, and the connecting component 4116 is provided with a limiting hole through which the limiting rod passes and slides in cooperation with the limiting hole.

[0191] In some embodiments, the feed rod mechanism 411 further includes a position detection component 4118, which is disposed on the fifth support component 4111 and configured to detect the position of the expansion shaft tie rod 4114 relative to the expansion shaft body 4113.

[0192] The position detection component 4118 includes a photoelectric switch 41181 and a sensing plate 41182. The photoelectric switch 41181 is fixedly mounted on the fifth support component 4111, and the sensing plate 41182 is fixedly mounted on the connector 4116 and moves synchronously with the connector 4116. The photoelectric switch 41181 can detect the position of the connector 4116 by detecting the position of the sensing plate 41182, thereby realizing the position detection of the expansion shaft body 4113.

[0193] The lifting mechanism 42 includes a lifting guide 422, a lifting moving part 423, and a lifting drive assembly 421.

[0194] The lifting guide 422 is arranged vertically; the lifting moving part 423 is movably arranged on the lifting guide 422, and the material strip extraction mechanism 41 is fixedly arranged on the lifting moving part 423; the lifting drive assembly 421 is connected to the lifting moving part 423 and can drive the lifting moving part 423 and the material strip extraction mechanism 41 to move synchronously along the lifting guide 422.

[0195] The lifting mechanism 42 can be a ball screw linear module, a gear and rack linear module, a linear motor module, or a synchronous belt linear module, etc., with a synchronous belt linear module being preferred.

[0196] Optionally, the lifting mechanism 42 further includes a lifting detection device configured to detect the moving position of the lifting moving member 423. The lifting detection device includes a photoelectric switch fixedly mounted on the lifting guide member 422 and a sensing plate fixedly mounted on the lifting moving member 423.

[0197] The rotating mechanism 43 includes a rotary table assembly 432 and a rotating drive assembly 431.

[0198] The rotary table assembly 432 is fixedly connected to the lifting guide 422 of the lifting mechanism 42; the rotary drive assembly 431 is connected to the rotary table assembly 432 and can drive the rotary table assembly 432 and the lifting mechanism 42 to rotate synchronously.

[0199] The rotating mechanism 43 is an electric rotating device.

[0200] First, the rotary drive assembly 431 drives the rotary table assembly 432 to rotate, adjusting the lifting mechanism 42 to a specified angle. The lifting drive assembly 421 drives the lifting moving part 423 to move along the lifting guide part 422 to the position of the workpiece support. At this time, the push-pull drive assembly 4122 drives the fifth support assembly 4111 and the push-pull claw 4121 to move, hooking the workpiece support and inserting the expansion shaft body 4113 into the center hole of the material tray. Then, the expansion shaft drive assembly 4112 drives the expansion shaft pull rod 4114 to move axially along the expansion shaft body 4113, causing the expansion shaft body 4113 to expand and fix the material tray. After that, the winding drive assembly 41151 drives the rotating part 41152 and the expansion shaft body 4113 to rotate synchronously to realize winding.

[0201] As shown in Figures 28-32, the receiving unit 3 includes a main frame 31, a lifting frame 32, a receiving assembly, a drive mechanism, and a conveyor belt 33;

[0202] Specifically, the drive mechanism is fixed on the main frame 31 and is connected to the lifting frame 32 in a transmission manner, and is configured to drive the lifting frame 32 to move up and down along the main frame 31. At least two pulleys 34, preferably idler pulleys, are rotatably connected on the lifting frame 32.

[0203] The pulley 34 rises and falls synchronously with the lifting frame 32, and the conveyor belt 33 is wound around at least two of the pulleys 34. The conveyor belt 33 is fixedly connected to the main frame 31 and the receiving assembly.

[0204] Specifically, a portion of one side of the conveyor belt 33 is fixedly connected to the main frame 31, and a portion of the other side of the conveyor belt 33 is fixedly connected to the receiving assembly.

[0205] With this structure, the lifting frame 32 is driven to move along the main frame 31 by the drive mechanism, which drives the pulley 34 to rise and fall synchronously and rotate. This allows the conveyor belt 33 to drive the receiving component to move twice the distance along the lifting frame 32. If the lifting frame 32 moves one distance, the pulley 34 and the conveyor belt 33 will drive the receiving component to move twice the distance, thus achieving a multiple movement. This allows the receiving component to move a longer distance with a shorter drive stroke, saving height space and facilitating the replacement of material strips on SMT.

[0206] In some embodiments, the main frame 31 is provided with a first guide rail 35 in the vertical direction. The first guide rail 35 is configured to lift the lifting frame 32. The lifting frame 32 is provided with at least two first sliders 36 on the side facing the main frame 31. The sliders are slidably connected to the first guide rail 35. Providing at least two first sliders 36 can provide sufficient support for the lifting frame 32, so that the lifting frame 32 can maintain balance and thus smoothly lift and lower along the first guide rail 35.

[0207] Furthermore, the lifting frame 32 is provided with two second guide rails 37 on the side opposite to the main frame 31. The two second guide rails 37 are parallel and spaced apart in the vertical direction. The second guide rails 37 are configured to lift the receiving assembly. The receiving assembly is provided with at least two second sliders 38. The two second sliders 38 are slidably connected to the second guide rails 37 respectively. The two second guide rails 37 are parallel to the first guide rail 35, and the first guide rail 35 is located at the center between the two second guide rails 37 in the vertical direction. That is, the two second guide rails 37 are symmetrically arranged on both sides of the first guide rail 35, thereby ensuring that the receiving assembly can be smoothly lifted and lowered along the second guide rails 37.

[0208] In some embodiments, the driving mechanism includes a drive motor 39, a lead screw 310, and a third slider 311;

[0209] Specifically, the drive motor 39 is fixed on the main frame 31, specifically located at the bottom of the main frame 31 and on one side of the first guide rail 35 and the lifting frame 32, configured to provide power for lifting the lifting frame 32. One end of the lead screw 310 is connected to the power output shaft of the drive motor 39, and the other end of the lead screw 310 is rotatably connected to the main frame 31 through a bearing. The lead screw 310 is arranged parallel to the first guide rail 35. The third slider 311 and the lead screw 310 form a ball screw pair. The third slider 311 is fixedly connected to the lifting frame 32. The drive motor 39 drives the lead screw 310 to rotate, causing the third slider 311 to rise and fall along the lead screw 310, thereby driving the lifting frame 32 to rise and fall along the first guide rail 35, thus realizing a single stroke of the lifting frame 32.

[0210] In some embodiments, the receiving assembly includes a fixed plate 312, an alignment plate 313, a support shaft 314, and an adjustment mechanism. Specifically, the adjustment mechanism is disposed on the fixed plate 312, and the alignment plate 313 is disposed on the side of the fixed plate 312 away from the main frame 31 via the adjustment mechanism. There is a gap between the alignment plate 313 and the fixed plate 312, and the gap is configured to receive a material tray. The adjustment mechanism is configured to adjust the gap between the alignment plate 313 and the fixed plate 312 in order to adaptably fix material trays of different widths. A plurality of support shafts 314 are vertically fixed on the fixed plate 312 to support the material trays.

[0211] In use, the receiving assembly is moved to a suitable height, and the robotic arm is used to place the tray within the gap between the alignment plate 313 and the fixing plate 312, so that the tray falls on the support shaft 314. Then the receiving assembly is moved again to transfer the material strip to the target position for the next process.

[0212] In some embodiments, the adjustment mechanism includes a first telescopic motor 315, a first L-shaped plate 316 and a second L-shaped plate 317, wherein the first L-shaped plate 316 and the second L-shaped plate 317 are configured to connect the fixed plate 312 and the alignment plate 313.

[0213] Specifically, the first telescopic motor 315 is fixed to one end of the fixed plate 312, the vertical sections of the first L-shaped plate 316 and the second L-shaped plate 317 are respectively fixed to both ends of the alignment plate 313, the output shaft of the first telescopic motor 315 is vertically connected to the vertical section of the first L-shaped plate 316, and the horizontal sections of the first L-shaped plate 316 and the second L-shaped plate 317 are respectively provided with a third guide rail 318 and a fourth guide rail 319. A fourth slider 320 and a fifth slider 321 are slidably connected to the third guide rail 318 and the fourth guide rail 319, respectively. The fourth slider 320 is fixedly connected to the first telescopic motor 315, and the fifth slider 321 is fixedly connected to the other end of the fixed plate 312.

[0214] In use, the first telescopic motor 315 pushes the first L-shaped plate 316, causing the horizontal sections of the first L-shaped plate 316 and the second L-shaped plate 317 to move synchronously along the third guide rail 318 and the fourth guide rail 319, respectively, thereby changing the spacing between the alignment plate 313 and the fixing plate 312 to realize the insertion and fixing of the material tray. The third guide rail 318 and the fourth guide rail 319 are each provided with a stop block that plays a limiting role at the end opposite to the alignment plate 313.

[0215] Furthermore, it also includes a support plate 322, a fifth guide rail 323, a sixth slider 324, a connecting plate 325, and a second telescopic motor 326. The second telescopic motor 326 is fixed to the bottom of the fixed plate 312. The two fifth guide rails 323 are vertically arranged on the side of the fixed plate 312 away from the main frame 31. The two sixth sliders 324 are slidably connected to the two fifth guide rails 323 respectively. The two ends of the connecting plate 325 are fixed to the two fifth sliders 321 respectively. The output shaft of the second telescopic motor 326 is connected to the middle of the connecting plate 325 to drive the connecting plate 325 to move up and down along the fifth guide rails 323. The pallets 322 are vertically fixed at both ends of the connecting plate 325. This arrangement allows the second telescopic motor 326 to push the pallets 322 up and down along the fifth guide rail 323 via the connecting plate 325. This allows the pallets 322 to move up and down within the gap between the fixed plate 312 and the alignment plate 313. Before placing the tray, the pallets 322 are first raised to the top of the fifth guide rail 323. After the tray enters the gap, it is first received by the two pallets 322. At this time, the second telescopic motor 326 lowers the pallets 322 at a uniform speed, allowing the tray to enter the gap steadily and finally fall onto the support shaft 314, preventing the tray from being damaged due to excessive falling speed.

[0216] In some embodiments, the centers of the plurality of support shafts 314 are located on the same arc and are configured to jointly support the material tray. Specifically, there are four support shafts 314, two of which are located near the bottom of the fixing plate 312 and are configured to support material trays with smaller diameters. The other two are located higher at both ends of the fixing plate 312 and are configured to support material trays with larger diameters. The surface of the support shafts 314 is covered with rubber sleeves, which play a role in buffering and shock absorption to avoid hard contact with the material tray. The two support shafts 314 located near the bottom of the fixing plate 312 are located below the connecting plate 325 and are configured to limit the lowest descent position of the connecting plate 325.

[0217] In some embodiments, a clamping mechanism 327 is further included, which is configured to fix the conveyor belt 33. There are two clamping mechanisms 327, which are respectively fixed on the main frame 31 and the receiving assembly. Specifically, the two pulleys 34 are arranged one above the other on the lifting frame 32. One clamping mechanism 327 is fixed on the main frame 31 near the upper pulley 34, and the other clamping mechanism 327 is fixed on the fixing plate 312 near the lower pulley 34. Specifically, the clamping mechanism 327 includes a clamping plate and a pressure plate. The conveyor belt 33 passes between the clamping plate and the pressure plate. The clamping plate and the pressure plate are fixed by bolts to clamp the conveyor belt 33.
