Description
Technical Field
[0001] This invention relates to the technical field of SMT surface mount technology, and more specifically, to a fully automatic SMT receiving machine and its shaping and receiving method. Background Technology
[0002] On SMT (Surface Mount Technology) production lines, pick-and-place machines require a continuous supply of material from reels. When the previous reel runs out of material, the beginning of a new reel needs to be connected to the end of the old reel to ensure the production line continues to operate without interruption. With increasing automation requirements, automatic feeding machines are gradually replacing traditional manual feeding.
[0003] During transportation, storage, and turnover, the side panels of the material tray are easily subjected to compression or collision, resulting in inward concavity and curling or outward curling plastic deformation. Deformed side panels can cause the material strip to jam, deviate, or scatter during release, making it impossible to accurately pull out and position the strip end, leading to inaccurate cutting lengths, misaligned splicing, or even splicing failure. Currently available SMT automatic splicing equipment typically lacks automatic correction functions for deformed tray side panels. Faced with deformed trays, the only option is to stop the machine with an alarm and rely on manual repositioning. This manual correction is not only time-consuming and labor-intensive but also produces poor shaping results and low consistency, severely impacting the smoothness and reliability of the splicing operation.
[0004] In summary, there is an urgent need for a fully automatic SMT receiving machine that can automatically feed materials and automatically correct and reshape deformed tray sides. This would solve the problems of material jamming, receiving failure, and high degree of manual intervention caused by tray deformation in existing technologies, thereby truly achieving efficient and fully automated operation of SMT receiving operations. Summary of the Invention

During the shaping process, the material tray is rotated to release the material strip. The material head clamping mechanism is used to clamp the end of the material strip of the material tray that has been shaped at the shaping position, and pull the end of the material strip outward; A cutting mechanism is used to cut the empty portion of the material strip pulled out by the material head clamping mechanism; The receiving mechanism is used to receive the cut end of the material strip and connect it to the end of another material strip.

The mounting frame is provided with a pin, a first rotary drive module that drives the pin to rotate, an inner support assembly, and an outer clamping assembly. The outer clamping assembly is used to clamp the tray in the material storage box at the loading position. The first lateral drive assembly drives the outer clamping assembly and the tray to move laterally to the shaping position. When the tray is in the shaping position, the pin is inserted into the central shaft hole of the tray to fix it. The inner support assembly is inserted into the wire cavity at the outer edge of the tray to push the two sides of the tray outward to a preset distance. The outer clamping assembly limits the two sides of the tray from the outside.

The cutting mechanism includes a vision imaging component, a pressing component, a cutting component, and a winding component. The pressing component has a first material channel with adjustable spacing. The material head clamping mechanism pulls the clamped material strip end to the winding component and releases the material strip end after the winding component starts winding the material strip.

[0012] The SMT fully automatic receiving machine of the present invention includes a receiving platform with a clearance hole for avoiding the cutting component; the cutting component includes a blade holder, a cutter that is in contact with the blade holder and can move vertically relative to it, a fixed base, a sliding block slidably connected to the fixed base, a second lateral movement drive component for driving the sliding block to move laterally, and a guide module connected between the sliding block and the blade holder and the cutter; the blade holder has a through hole for the feed tape to move through; the guide module converts the lateral movement of the sliding block into the relative vertical movement of the blade holder and the cutter, and the blade holder and the cutter have at least the following stages during the movement: In the first stage, the cutter is located outside the through hole, and the material strip can move freely through the through hole; In the second stage, the cutter moves vertically along the outer surface of the cutter holder and approaches the inner wall of the through hole, gradually reducing the opening area of the through hole and clamping and fixing the material strip onto the inner wall of the through hole. In the third stage, the cutter continues to move along the outer surface of the cutter holder, and the cutting edge of the cutter is tangent to the outer edge of the through hole, so that the opening of the through hole is completely closed, thereby cutting the material strip.
[0013] The SMT fully automatic receiving machine of the present invention includes a guide module comprising a positioning block disposed below the blade holder and the cutter, two second connecting rods respectively vertically slidably connected to the positioning block, and a second guide groove and a third guide groove disposed on the sliding block; the positioning block is provided with two parallel Z-axis sliding grooves for the two second connecting rods to pass through respectively; Of the two second connecting rods, the upper end of one second connecting rod is fixedly connected to the blade holder, and the lower end is slidably connected to the second guide groove via a first roller; the upper end of the other second connecting rod is fixedly connected to the cutter, and the lower end is slidably connected to the third guide groove via a second roller.

[0015] On the other hand, the present invention provides a shaping and receiving method for an SMT fully automatic receiving machine, using any of the SMT fully automatic receiving machines described above, wherein the method includes the following steps: S1. Material tray loading and shaping: The material tray transfer and shaping mechanism picks up the material tray from the material storage box and transfers it to the processing position. It shapes the two side plates of the material tray to correct the deformation and drives the material tray to rotate and release the material strip during the shaping process. S2, Strip Pulling and Cutting: The strip clamping mechanism clamps the end of the shaped strip and pulls it outward, while the cutting mechanism cuts off the empty part of the pulled-out strip end; S3, Material Belt Connection: The robot arm, in conjunction with the transmission structure, transfers another material belt to the receiving mechanism. The receiving mechanism receives the cut end of the material belt and connects it to the end of the other material belt. S4. Empty Disk Recycling: After receiving the material, the robot arm will pick up the empty disk and transfer it to the empty disk recycling mechanism for collection.
[0016] Compared with the prior art, the present invention has the following beneficial effects: The beneficial effects of this invention are as follows: 1. This invention is the first in SMT fully automatic receiving machines to achieve fully automatic correction and reshaping of deformed tray side plates, completely solving the problems of material jamming and receiving failure caused by tray deformation. After the tray is loaded and before receiving, the two side plates of the tray are automatically shaped to correct their plastic deformation. This restores the tray to its normal shape, ensuring smooth and unbiased release of the material strip during subsequent release, and accurate pulling and positioning of the strip end. This significantly improves cutting accuracy and receiving success rate, avoiding machine stop alarms and manual intervention caused by tray deformation.
[0017] 2. During the shaping process of the material tray side plate, the material tray transfer and shaping mechanism of the present invention simultaneously drives the material tray to rotate and release the material strip. This ingenious design of "shaping and releasing at the same time" overlaps the shaping process and the material preparation process in terms of time, eliminating the need to perform a separate material release action after the shaping is completed. This effectively shortens the cycle time of the entire material receiving cycle and significantly improves the overall operating efficiency of the equipment.
[0018] 3. In this invention, the material tray transfer and shaping mechanism is responsible for shaping and initial feeding, the material head clamping mechanism precisely clamps and pulls the material head outward, the cutting mechanism cleanly and efficiently cuts off the empty material, and the receiving mechanism completes high-quality end splicing. Each mechanism performs its own function and operates smoothly, avoiding the problems of poor shaping effect and low consistency caused by manual manipulation. This ensures that each receiving operation is completed under standardized mechanical actions, guaranteeing the reliability of the final received product quality. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.
[0041] Example 1: A preferred embodiment of the present invention provides a fully automatic SMT receiving machine, such as... Figure 1 As shown, it includes: Material storage box 10 is used to store multiple material trays; The material tray transfer and shaping mechanism 20 is used to take out the material tray in the material storage box 10 and transfer it to the shaping position, and to shape the two side plates of the material tray to correct the plastic deformation of the side plates that are concave and curled inward or curled outward. During the shaping process, the material tray is rotated to release the material strip. The material head clamping mechanism 30 is used to clamp the end of the material strip of the material tray that has been shaped at the shaping position, and pull the end of the material strip outward; The cutting mechanism 40 is used to cut the empty part of the material strip pulled out by the material head clamping mechanism 30; The receiving mechanism 50 is used to receive the cut end of the material strip and connect it to the end of another material strip. Empty tray recycling mechanism 60 is used to collect empty trays left after receiving materials; The robotic arm 70 is used to grip and transfer the material tray between the material storage box 10, the tray transfer and shaping mechanism 20, the receiving mechanism 50, the material belt buffer mechanism 80 and the empty tray recycling mechanism 60.
[0042] This invention integrates automatic material picking and shaping of the material tray through the material tray transfer and shaping mechanism 20, ensuring smooth material release without jamming; the material head clamping mechanism 30 cooperates with the cutting mechanism 40 to automatically remove invalid empty material segments; the material tray is automatically loaded through the material tray transfer and shaping mechanism, and its loading and shaping paths do not interfere with the material picking and loading paths of the robot arm 70, resulting in reduced volume and high space utilization.
[0043] In this embodiment, the material storage box 10 can adopt an existing storage box structure, with multiple material trays stored vertically inside the box for easy material retrieval.
[0044] like Figure 2 As shown, the feed tray 1 has a central shaft hole 2 and a winding cavity 3 located on the outer edge, with side edges 4 on both sides of the winding cavity 3.
[0045] like Figures 3-5As shown, in this embodiment, the material tray transfer and shaping mechanism 20 includes a mounting frame 21 and a first transverse drive assembly 22 that drives the mounting frame 21 to move between the loading position and the shaping position; the first transverse drive assembly 22 can be a linear drive module or a lead screw drive module in the prior art. The mounting frame 21 is equipped with a pin 23, a first rotary drive module 24 that drives the pin 23 to rotate, an inner support assembly 25, and an outer clamping assembly 26. The outer clamping assembly 26 is used to clamp the material tray in the material storage box 10 at the loading position. The first lateral drive assembly 22 drives the outer clamping assembly 26 and the material tray to the shaping position. When the material tray is in the shaping position, the pin 23 is inserted into the central shaft hole of the material tray to fix the material tray. The inner support assembly 25 is inserted into the wire cavity of the outer edge of the material tray to push the two sides of the material tray outward to a preset distance. In this embodiment, the preset distance refers to the standard distance between the two sides 4 of the material tray 1 in the undeformed state, or the target distance set according to the requirements of the subsequent receiving process (for example, 0.1-0.5mm larger than the standard distance to compensate for springback). The outer clamping assembly 26 limits the two sides of the material tray from the outside to prevent them from expanding excessively. When the first rotary drive module 24 drives the tray 1 to rotate, the center of the tray is fixed by the pin 23, the inner support component 25 expands outward from the inside, and the outer clamp component 26 limits the movement inward from the outside. The three work together to effectively correct the concave, folded or wavy deformation of the side of the tray and restore its standard spacing and flatness.
[0046] In this embodiment, the pin 23 can adopt a technical solution such as including a pin body and an expansion sleeve sleeved around the outer periphery of the pin body, which has a retracted state and an unfolded and engaged state. When the pin 23 is in the retracted state, the expansion sleeve contracts to form a shaft shape so as to smoothly insert into the central shaft hole 2 of the material tray 1. When the pin 23 is in the unfolded and engaged state, the pin body pushes the expansion sleeve outward, causing the outer diameter of the expansion sleeve to expand, thereby tightening and fixing the inner wall of the central shaft hole 2 of the material tray 1, and realizing the reliable positioning of the material tray. By driving the pin body to move axially relative to the expansion sleeve to change the outer diameter adjustment of the expansion sleeve, it can adapt to different hole sizes and can be fixedly connected to multiple material trays with different central hole shafts, with high compatibility.
[0047] In this invention, by adjusting the clamping force of the outer clamping assembly 26, it can not only provide a large clamping force to act as a material handling fixture, thus removing the material tray from the storage box, but also switch to a low clamping force limiting mode during shaping, thus limiting the shape. After the outer clamping assembly 26 moves the material tray to the shaping position, the pin 23 is inserted into the central shaft hole of the material tray and fixed to it; the outer clamping assembly 26 adjusts the clamping force to release the material tray, switching to an external pressure limiting mode; after the material tray is fixed, the inner support assembly 25 and the outer clamping assembly 26 move to the working height and are respectively inserted into the winding cavity 3 of the material tray and located outside the material tray; the inner support assembly is inserted into the winding cavity to push the deformed side outward, while the outer clamping assembly is used to resist and limit from the outside. This "internal support and external pressure" combination can force the side plate to be corrected to the preset standard spacing. During the process of the material tray being rotated by the first rotation drive module, the internal support component and the external clamping component continuously apply force to the material tray side plate. This dynamic rolling or correction method can cover the entire circumference of the material tray side plate, avoiding the dead corners that may exist in static shaping, ensuring that the side plate is flattened on the entire circumference, and completely eliminating geometric errors.
[0048] After the above-mentioned shaping, the material trays were restored to their normal spacing and flatness, eliminating abnormal interference between the side plate edges and the guiding mechanism. This effectively avoids phenomena such as changes in the discharge trajectory, scraping of the material belt edges, deviation, or shaking caused by deformation, fundamentally preventing the folded or curled parts from blocking the material belt conveying path, eliminating jamming, belt breakage, and equipment downtime, and ensuring the smoothness of material belt transmission.
[0049] In this embodiment, a shaping position is provided on one side of the mounting frame 21; the pin 23 moves closer to or away from the shaping position via a moving drive component (not shown); the inner support assembly 25 and the outer clamping assembly 26 are movably mounted on the mounting frame 21 via a first lifting assembly 27 and a second lifting assembly 28, respectively, to move closer to or away from the shaping position. In this embodiment, the first lifting assembly 27 and the second lifting assembly 28 are respectively disposed on the two side surfaces of the mounting frame 21. This dual-sided split layout avoids spatial interference between the inner support and the outer clamping actions, allowing the inner support assembly and the outer clamping assembly to be independently adjusted without affecting each other, ensuring the independence and stability of the shaping action. The first lifting assembly 27 and the second lifting assembly 28 can both adopt common drive structures in the prior art, such as linear modules, telescopic motors, cylinders with guide rod structures or screw lifting mechanisms, conveyor belts and rotary drive motors, as long as they can achieve linear reciprocating motion. After the outer clamping assembly moves the tray to the shaping position, the pin 23 is inserted into the central shaft hole of the tray and fixed to it; the outer clamping assembly adjusts the clamping force to release the tray and switch to the external pressure limiting mode; after the tray is fixed, the inner support assembly 25 and the outer clamping assembly 26 move to the working height and are respectively inserted into the tray winding cavity 3 and located on the outside of the tray.
[0050] Furthermore, a rotary motor 29 is provided between the mounting frame 21 and the first transverse drive assembly 22 to drive the mounting frame 21 to rotate as a whole, which facilitates material picking and loading from multiple angles.
[0051] like Figure 6 As shown, in this embodiment, the inner support assembly 25 includes a first sliding plate 251 movably connected to the mounting frame 21, two parallel support blocks 252, a fixing block 253 fixedly connected to the first sliding plate 251, a guide block 254 slidably connected to the first sliding plate 251 longitudinally, two first connecting rods 255, and a lifting drive 256 that drives the guide block 254 to move downward along the Z-axis. The guide block 254 has two parallel channels (not shown) through which the first connecting rods 255 pass. The fixing block 253 has two longitudinally arranged first guide grooves 2531. The distance between the two first guide grooves 2531 gradually widens from top to bottom. The first ends of the two first connecting rods 255 are respectively connected to the two support blocks 252, and the second ends of the two first connecting rods 255 are slidably connected to the two first guide grooves 2531 via guide members 257. In this embodiment, the guide member 257 can be a roller or a slider as used in the prior art.
[0052] When the lifting drive 256 drives the guide block 254 to move downward along the Z-axis, the guide block 254 drives the two first connecting rods 255 to move downward. Since the second ends of the first connecting rods 255 are restricted to slide within the first guide groove 2531 by the guide 257, and the distance between the two first guide grooves 2531 on the fixed block 253 gradually widens from top to bottom, the second ends of the two first connecting rods 255 will slide along the two first guide grooves 2531 respectively during the downward movement. Due to the change in the distance between the two first guide grooves 2531, the two first connecting rods 255 will move laterally in the two channels simultaneously during the downward movement, thereby causing the two support blocks 252 to open outward, realizing the action of opening the two sides 4 of the material tray outward. Conversely, when the guide block 254 moves upward, the second ends of the two first connecting rods 255 approach each other along the first guide groove 2531, thereby causing the two support blocks 252 to approach each other, releasing the inner support limit on the material tray. Based on the width of the material strip, the stroke of the lifting drive component 256 can be controlled to adjust the opening distance between the two support blocks 252, thereby accurately controlling the target distance between the two sides 4 of the preset material tray to adapt to the shaping needs of material trays of different specifications and sizes, with high compatibility.
[0053] The aforementioned structure allows the two support blocks to move horizontally while simultaneously moving vertically, enabling a single drive component to complete both insertion and opening actions at the same time. This simplifies the transmission chain and reduces control complexity. The structure is compact, the transmission is precise, and it possesses a self-locking characteristic: after the lifting drive component stops, the support block position remains stable, maintaining a constant opening force and preventing changes in spacing due to external force fluctuations.
[0054] In this embodiment, the upper ends of both first guide grooves 2531 are inclined outward and upward in the same direction; the upper end of the inner first guide groove 2531 is lower than the upper end of the outer first guide groove 2531, and the lower end of the inner first guide groove 2531 is lower than the lower end of the outer first guide groove 2531; the middle part of the two first guide grooves 2531 is vertically arranged.
[0055] The above structure further optimizes the movement guidance of the guide blocks, ensuring smooth lifting and lowering. The special shape of the first guide groove 2531, such as its outward tilt at the top and vertical position in the middle, allows the two support blocks 252 to move rapidly outward during the initial opening phase to insert into the winding cavity, followed by a vertical section. This allows the support blocks to quickly insert into the winding cavity first, then stably open the sides while maintaining the spacing, avoiding damage to the material tray due to sudden speed changes. The entire motion curve is reasonable, balancing insertion efficiency and shaping stability.
[0056] like Figure 4 As shown, in this embodiment, the outer clamping assembly 26 includes a second sliding plate 261 movably connected to the mounting frame 21, a clamping plate 262 cooperating with the second sliding plate 261 to press and limit the material tray, and a clamping drive module 263 that drives the clamping plate 262 closer to or further away from the second sliding plate 261, such as a telescopic motor or lead screw motor fixedly connected to the clamping plate 262 in the prior art; the maximum clamping distance between the second sliding plate 261 and the clamping plate 262 is not less than the outer edge distance of the two sides when the inner support assembly 25 expands the two sides of the material tray to a preset distance. Typically, the clamping distance is equal to or slightly greater than this outer edge distance to limit the side position from the outside and prevent excessive outward or inward retraction. It can be understood that the pressure plate can be one or two pieces. When set as one piece, it forms a single-sided movable clamping with the second sliding plate; when set as two pieces, the second sliding plate can serve as a fixed side plate. In this embodiment, the pressure plate is preferably a movable side plate, and the second sliding plate is a fixed side plate, with the two cooperating to achieve clamping.
[0057] Furthermore, such as Figure 7As shown, the inner support assembly 25 is further provided with a guide wheel adjustment assembly 27 on one side of the discharge port; the guide wheel adjustment assembly 27 includes a guide drive member 271 for supporting and guiding the material belt to move outward, two limiting plates 272 respectively disposed on both sides of the guide drive member 271, and a first adjustment assembly 273 for adjusting the distance between the two limiting plates 272; the first adjustment assembly 273 can be a telescopic drive structure such as a motor or cylinder in the prior art, one of the limiting plates 272 is fixedly connected to the drive shaft of the first adjustment assembly 273, and the limiting plate 272 is movably connected to the guide drive member 271 to adjust the gap between the two limiting plates 272; the gap between the two limiting plates 272 forms a wire passage 274 through which the feeding belt passes.
[0058] In this embodiment, the material head clamping mechanism 30 includes a gripper, a drive motor that controls the gripper to pick up or release material, and a linear drive module that drives the gripper and drive motor to move closer to or away from the shaping position; the gripper and drive motor cooperate to grip the end of the material strip, and the linear drive module is used to pull the end of the material strip outward to a preset length.
[0059] like Figure 8 As shown, the cutting mechanism 40 is located on one side of the material head clamping mechanism 30. The cutting mechanism 40 includes a vision imaging component 41, a pressing component 42, a cutting component 43, and a winding component 44. The material head clamping mechanism 30 pulls the clamped material strip end to the winding component 44 and releases the material strip end after the winding component 44 starts winding the material strip. The vision imaging component 41 is signal-connected to the pressing component 42 and is used to trigger the pressing component 42 to press the material strip when the first product on the material strip is detected. The cutting component 43 is located between the pressing component 42 and the winding component 44 and is used to cut the empty part of the material strip at a preset length before the first product after the pressing component 42 presses the material strip and the winding component 44 continues to wind the material strip to make it taut. The visual imaging component 41 is a CCD camera in the prior art. It is positioned directly above the moving path of the material strip and is used to collect image information of the material strip surface in real time and transmit it to an external controller (such as a PLC or industrial computer). It accurately identifies the boundary between the components (products) on the material strip and the empty material section through existing image recognition algorithms.
[0060] like Figure 9As shown, the pressing assembly 42 includes a first feed channel 421 through which the feed strip passes, a second adjustment assembly 422 for adjusting the width of the first feed channel 421, and a pressing member 423 for pressing and fixing the feed strip in the first feed channel 421. The pressing member 423 can be a motor-driven pressing block, which is located above the first feed channel 421. When a trigger signal is received from the visual imaging assembly 41, the pressing block moves downward to press the feed strip tightly against the bottom surface of the first feed channel 421, thereby achieving reliable fixing of the feed strip.
[0061] In this embodiment, the first material channel 421 is formed by two guide plates arranged opposite to each other; one guide plate is a fixed structure and the other guide plate is a movable structure; the second adjustment component 422 can be a lead screw and nut pair, motor or telescopic cylinder and other driving components in the prior art, and its driving end is connected to the movable guide plate. By driving the guide plate to translate, the distance between the two guide plates is changed, thereby adapting to material strips of different widths and improving the compatibility of the equipment.
[0062] The cutting assembly 43 can adopt existing cutting structures such as pneumatic shears, guillotine driven by a linear module, or automatic cutter; its cutting position is controlled by an external controller to ensure that the cut is accurately located at a preset length before the first product, avoiding damage to effective components; The roll assembly 44 can be a structure with a rotary motor and a take-up reel driven by it, to provide continuous and stable traction force, automatically roll up and collect the cut empty waste strip, and keep the work area clean.
[0063] During operation, the material head clamping mechanism 30 first clamps the end of the material strip and pulls it to the winding assembly 44 for handover. After the winding assembly 44 begins winding the material strip, the material head clamping mechanism 30 releases the end of the material strip, and the winding assembly 44 continues to pull the material strip. During this process, the vision imaging assembly 41 monitors the surface of the material strip in real time. When the first product on the material strip is detected, the pressing assembly 42 is triggered to press and fix the material strip. At this time, the winding assembly 44 continues to wind a short distance, forcing the material strip between the pressing assembly 42 and the winding assembly 44 to taut. Finally, the cutting assembly 43 cuts the taut empty material portion at a preset length on the material strip before the first product. Through the coordinated operation of the above units, utilizing precise vision positioning and the tensioning of the pressing and winding, the material strip is cut while taut, ensuring not only a clean cut but also automatic identification and removal of empty material portions, greatly improving material receiving efficiency and material strip utilization.
[0064] like Figure 10As shown, in this embodiment, the receiving mechanism 50 includes a receiving platform 51; the receiving platform 51 is provided with a second material channel, the second material channel including a first channel 02 for one material belt to pass through, a second channel 03 for another material belt to pass through, and a receiving channel 04 disposed between the first channel 02 and the second channel 03; the new material belt and the old material belt enter their respective channels from the left and right sides or the front and back sides, depending on the actual layout, and complete the docking and bonding at the middle receiving channel 04.
[0065] Alternatively, in order to accommodate strips of different widths, such as Figure 11 As shown, the receiving platform 51 adopts an adjustable width structure. Specifically, the receiving platform 51 includes a base 511, on which a first support plate 512 and a second support plate 513, parallel to each other, are arranged on the upper surface of the base 511. The first support plate 512 is fixedly connected to the base 511, serving as a reference side; the second support plate 513 is slidably connected to the base 511, for example, by a guide rail slider pair for horizontal sliding. Each of the opposite surfaces of the first support plate 512 and the second support plate 513 has a concave material groove d, which together form the second material channel. A telescopic cylinder 514 or a drive motor is also installed on the base 511, with its driving end fixedly connected to the second support plate 513, used to move the second support plate 513 closer to or further away from the first support plate 512, thereby adjusting the width of the material channel to match material strips of different widths, achieving high compatibility.
[0066] Both the first channel 02 and the second channel 03 are equipped with a material guiding component 52. The material guiding component 52 can be an active roller or a feeding belt structure in the prior art and a rotary motor that drives it to rotate. It is used to drive the new or old material belt to move towards the receiving channel 04 to realize automatic feeding and ensure that the material belt is stably conveyed forward.
[0067] like Figure 12 As shown, in order to prevent the material strip from floating or tilting upward from the material channel, a flip-pressing unit is provided on one side of the first channel 02 and the second channel 03. The flip-pressing unit includes a material strip pressing component 53 that can rotate relative to the receiving platform 51, and an unlocking component 54 that releases the pressing state of the material strip pressing component 53. A cutting assembly 55 is provided between the first channel 02 and the receiving channel 04, and between the second channel 03 and the receiving channel 04; a material attaching module 56 is also provided on one side of the receiving platform 51 for splicing the ends of the two material strips.
[0068] This invention features a flip-pressing unit on one side of both the first and second channels. Each unit includes a strip pressing assembly that rotates relative to the receiving platform and an unlocking assembly to release the pressing state. During material feeding and cutting, the strip pressing assembly quickly flips and firmly presses the strip, effectively preventing it from shifting or shrinking during cutting and sticker application, ensuring the flatness of the cut end and the accuracy of the receiving. The unlocking assembly makes releasing the pressing state quick and easy, facilitating smooth strip feeding and rapid replacement, thus improving the overall convenience and stability of the operation.
[0069] Specifically, the strip pressing assembly 53 includes a mounting base 531 fixedly connected to the receiving platform 51, a pressing block 532 rotatably connected to the mounting base 531, and an elastic element 533 that provides elastic force to the pressing block 532 to keep it pressed against the material channel. This elastic element 533 can be a torsion spring or a tension spring, as is common in the art. In its natural state, the elastic force of the elastic element 533 forces the pressing block 532 downwards, i.e., towards the material channel, so that the pressing block 532 presses and fixes the strip in the material channel, facilitating subsequent cutting or receiving.
[0070] Optionally, the unlocking component 54 is used to overcome the elastic force of the elastic element 533 and lift the pressing block 532 when feeding or removing the material strip is required. Specifically, the unlocking component 54 includes a top block 541 and a lifting drive component 542 that drives the top block 541 to move along the Z-axis, using a telescopic cylinder or drive motor in the prior art; a roller 543 is rotatably provided on the top block 541 to roll in cooperation with the lower surface of the pressing block 532; the driving end of the lifting drive component 542 is fixedly connected to the top block 541, and by controlling the lifting and lowering movement of the top block 541, the roller 543 presses against the lower surface of the pressing block 532, causing the pressing block 532 to flip up and down to move closer to or away from the material strip on the feed channel.
[0071] When the material strip needs to be released, the lifting drive 542 drives the top block 541 to rise, and the roller 543 presses against the lower surface of the pressing block 532, overcoming the elastic force of the elastic element 533 and causing the pressing block 532 to flip upward, thus detaching from the material strip surface. When re-pressing is required, the lifting drive 542 drives the top block 541 to fall, and the pressing block 532 automatically resets and presses the material strip under the action of the elastic element 533. This rolling engagement method reduces friction and improves the smoothness of operation and service life.
[0072] like Figure 10 As shown, the receiving platform 51 is provided with a clearance hole 05 for avoiding the cutting component 55.
[0073] like Figure 13 and Figure 14As shown, in this embodiment, the cutting assembly 55 includes a blade holder 551, a cutter 552 that is fitted to the blade holder 551 and can move vertically relative to it, a fixed base 553, a sliding block 554 that is slidably connected to the fixed base 553, a second lateral movement drive assembly 555 that drives the sliding block 554 to move laterally, and a guide module 556 connected between the sliding block 554 and the blade holder 551 and the cutter 552. The second lateral movement drive assembly 555 can be a drive motor or a lead screw drive module in the prior art. The blade holder 551 is provided with a through hole 06 through which the feed strip moves. The width of the through hole 06 is not less than the width of the feed strip, and the feed strip passes through the through hole 06. The guide module 556 converts the lateral movement of the sliding block 554 into the relative vertical movement of the blade holder 551 and the cutter 552.
[0074] Specifically, the guide module 556 includes a positioning block 5561 disposed below the cutter holder 551 and the cutter 552, two second connecting rods 5562 that are vertically slidably connected to the positioning block 5561, and a second guide groove 5563 and a third guide groove 5564 disposed on the sliding block 554; the positioning block 5561 is provided with two parallel Z-axis sliding grooves (not shown in the figure) through which the two second connecting rods 5562 pass respectively; of the two second connecting rods 5562, the upper end of one second connecting rod 5562 is fixedly connected to the cutter holder 551, and the lower end is slidably connected to the second guide groove 5563 through a first roller 5565; the upper end of the other second connecting rod 5562 is fixedly connected to the cutter 552, and the lower end is slidably connected to the third guide groove 5564 through a second roller 5566.
[0075] Specifically, the second guide groove 5563 is a continuous trajectory, specifically including a horizontal first transverse groove a1 and a first inclined groove b1 that slopes downward and outward from the first end of the first transverse groove a1. The third guide groove 5564 is also a continuous trajectory, specifically including a horizontal second transverse groove a2, a second inclined groove b2 that slopes downward and outward from the first end of the second transverse groove a2, and a third inclined groove b3 that slopes downward and outward from the second end of the second transverse groove a2 (the other end opposite to the first end).
[0076] Based on the shape of the guide groove, when the second lateral movement drive assembly 555 drives the sliding block 554 to move laterally, the first roller 5565 and the second roller 5566 roll along their respective guide grooves, thereby driving the second connecting rod 5562, the tool holder 551, and the cutter 552 to produce vertical movements with different timings and speeds. The tool holder 551 and the cutter 552 have the following multiple stages during the movement process: First stage (yielding stage): The first roller 5565 is located within the first transverse groove a1, and the second roller 5566 is located within the third inclined groove b3. At this time, the cutter holder 551 and the cutter 552 are in their initial yielding state, with the cutter 552 located outside the through hole 06 (i.e., not entering the opening area of the through hole 06). The material strip can pass freely through the through hole 06 without obstruction. This stage is used for feeding.
[0077] The second stage (engagement and fixing stage): The second lateral movement drive assembly 555 drives the sliding block 554 to move laterally in a certain direction (e.g., to the right). The first roller 5565 first moves horizontally a certain distance in the first transverse groove a1, then slides into the first inclined groove b1, and is forced to move downward along the inclined groove. Through the first second connecting rod 5562, it drives the cutter holder 551 to move downward a small distance, so that the inner wall of the channel of the cutter holder 551 presses against the material strip on the receiving platform 51, achieving the initial fixing of the material strip. At the same time, the second roller 5566 moves from the third inclined groove b3 towards the second transverse groove a2, driving the cutter 552 to move upward. The cutter 552 moves vertically upward along the outer surface of the cutter holder 551, gradually approaching and entering the cutting inner wall of the through hole 06 (i.e., the inner wall of the through hole 06 near the cutter 552). As the cutter 552 enters, the opening area of the through hole 06 gradually decreases, thereby biting and fixing the material strip, preventing the material strip from retracting or shifting at the moment of cutting. Alternatively, the lower inner wall of the through hole 06 is designed as a first inclined surface that slopes downward, while the side surface of the cutter 552 facing away from the through hole 06 (i.e. the side away from the contact surface of the cutter holder 551) is designed as a second inclined surface that slopes relative to the first inclined surface, thereby increasing the sharpness of the cutter head.
[0078] The third stage (cutting stage): The sliding block 554 continues to move laterally in the same direction. At this time, the first roller 5565 continues to slide downward along the first inclined groove b1, and the cutter holder 551 remains in a low-position pressing state; the second roller 5566 enters the second transverse groove a2. During this process, the cutter 552 moves closely tangentially to the cutter holder 551 in the vertical direction, and the cutting edge of the cutter 552 (i.e., its vertical cutting edge) is tangential to the outer edge of the through hole 06 (i.e., the junction between the upper surface of the cutter holder 551 and the through hole 06), so that the opening of the through hole 06 is completely closed. At this instant, the vertical surface of the cutter 552 is closely attached to the outer surface of the cutter holder 551, like a guillotine, using huge downward pressure to cleanly and neatly cut the material strip that has been clamped and fixed in the vertical direction. Since the cutting action only occurs in the vertical direction and the guide module 146 provides stable support, the cut is flat and burr-free.
[0079] Fourth stage (reset stage): The first roller 5565 continues to move downward along the first inclined groove b1, and the second roller 5566 moves from the second transverse groove a2 to the second inclined groove b2. The tip of the cutter gradually moves away from the through hole position of the cutter holder, so that the diameter of the through hole gradually returns to its original size, so that the feed belt can pass normally.
[0080] After the cutting is completed, the second transverse drive assembly 555 reverses the drive of the sliding block 554 to move back laterally, each roller moves in the opposite direction along the guide groove, and the knife holder 551 and the cutter 552 move in the opposite direction to cut again.
[0081] The above-mentioned material cutting component 55 cleverly utilizes the lateral driving force and generates timing and speed differences through guide grooves of different shapes, realizing the optimized cutting logic of "first allowing the material strip to pass normally, then engaging and fixing, and finally cutting", which significantly improves the cutting quality and stability.
[0082] By using a lateral drive source (second lateral drive component 555) and two sets of guide grooves with different timing (the second guide groove controls the lifting and lowering of the tool holder, and the third guide groove controls the lifting and lowering of the cutter), the differential motion between the tool holder and the cutter is cleverly realized. The structure is compact and the timing of the action is precise and controllable.
[0083] After both strips have been neatly trimmed and are positioned within receiving channel 04, they need to be joined together with a sticker. To do this, as follows: Figure 15 As shown, the applicator module 56 includes a sticker feeder 561 (e.g., a rotatable reel) that provides sticker tape, a conveyor roller assembly 562 (e.g., a common structure consisting of a motor-driven drive roller and multiple driven pressure rollers) that moves the tape outward, and an applicator assembly 563 that applies the sticker from the tape to the receiving channel 04 to bond the two tapes together. The applicator assembly 563 is a well-established existing structure in the art, typically including a lifting or translating applicator head, a lifting motor, and a linear module, capable of peeling the sticker from the release liner and accurately pressing it onto the seam of the two tapes for a secure connection.
[0084] like Figure 10 As shown, a material belt buffer mechanism 80 is also provided on one side of the receiving mechanism 50; preferably, as Figure 16 and Figure 17As shown, the tape buffer mechanism 80 includes a tape frame 81, a fixed plate 82 fixedly connected to the tape frame 81, and a movable plate 83 parallel to the fixed plate 82. The movable plate 83 can move laterally along the width direction of the tape frame 81. The tape frame 81, the fixed plate 82, and the movable plate 83 enclose each other to form a storage cavity (not shown) for longitudinally stacked tape. The tape buffer mechanism 80 also includes a third adjusting component 84 that moves the movable plate 83 closer to or further away from the fixed plate 82 to adjust the width of the storage cavity (not shown). By moving the movable plate laterally closer to or further away from the fixed plate 82 within the tape frame using the third adjusting component, the width of the storage cavity can be directly adjusted, allowing the same device to accommodate tapes of different widths, thus providing strong versatility.
[0085] In this embodiment, in order to provide a stable mounting base for the first adjustment component, the side surface of the fixed plate 82 facing away from the movable plate 83 is provided with an installation frame 85 for placing the third adjustment component 84; alternatively, the third adjustment component 84 can be the first adjustment component in the applicant's prior patent CN223810078U, the specific structure and principle of which are the same as the prior patent, and will not be described in detail here.
[0086] Alternatively, the third pitch adjustment component 84 may also employ existing drive components such as lead screw and nut pairs, gear and rack structures, or linear motors that can achieve linear reciprocating motion and have self-locking functions.
[0087] The upper end of the material frame is provided with a third material channel 86 through which the feeding belt passes and communicates with the storage cavity (not shown in the figure). Furthermore, to ensure the material belt maintains appropriate tension during transmission and reduce damage, a fourth adjusting component 87 is also provided on one side of the material frame 81 to adjust the inlet and outlet width of the third material channel 86. Adjusting the width of the third material channel 86 by the fourth adjusting component 87 not only allows for the smooth introduction of material belts of different widths but also provides a centering guide for the material belt, preventing it from deviating or wrinkling before entering the storage cavity (not shown in the figure). The fourth adjusting component 87 can adopt a structure similar to the first adjusting component 273, including a drive motor or telescopic cylinder and a movable guide plate, thereby achieving flexible and rapid adjustment of the material channel width.
[0088] Example 2 This invention also provides a shaping and receiving method for an SMT fully automatic receiving machine, using the SMT fully automatic receiving machine described in Embodiment 1 above. The method includes the following steps: S1. Material tray loading and shaping: The outer clamping component of the material tray transfer and shaping mechanism clamps the material tray from the material storage box, and the first lateral drive component moves it laterally to the shaping position; the pin is inserted into the central shaft hole of the material tray and is fixed by the expansion sleeve adjustment; the inner support component descends to open the two side plates of the material tray outward to the preset distance, and at the same time the outer clamping component changes from the clamping and fixing mode to the limiting mode to limit from the outside; the first rotation drive module drives the material tray to rotate and release the material strip, and the inner support and outer clamping components work together dynamically to flatten the plastic deformation such as inward concavity and outward folding of the side plates; when the material is shaped and discharged, the guide wheel adjustment component adjusts the distance between the two limiting plates according to the width of the material strip to form a suitable wire passage channel to ensure that the material strip is discharged smoothly without deviation; S2. Strip Pulling and Cutting: The pressing component of the cutting mechanism adjusts the spacing of the first material channel according to the strip width through the second spacing adjustment component to adapt to the strip; the material head clamping mechanism clamps the end of the shaped material tray and pulls it outward and to the winding component; after the winding component starts to wind the strip, the material head clamping mechanism releases the end, and when the vision imaging component detects the first product on the strip, it triggers the pressing component to press the strip; the winding component continues to wind the strip to make it taut, and the cutting component cuts the empty part of the strip at a preset length before the first product, accurately retaining the effective component segment; S3. Strip Receiving Connection: The receiving mechanism adjusts the distance between the first and second trays on the receiving platform according to the strip width via a drive motor, thereby adjusting the width of the second material channel. The robotic arm, in conjunction with the transmission structure, moves the end of the old strip ejected from the pick-and-place machine to the second channel. Two guiding components transport the new and old strips to the receiving channel in opposite directions. The pressing block of the flipping pressing unit presses the strip tightly to prevent deviation under the action of the elastic element. Under the lateral drive, the cutting component performs a gradual cutting action of "yielding-biting and fixing-closing and cutting" in sequence through different timing guide grooves of the guide module, cutting the ends of the two strips evenly. Then, the unlocking component lifts the pressing block to release the pressing state, and the attaching module accurately presses the receiving sticker onto the splice of the two strips. At the same time, the strip buffer mechanism adjusts the position of the movable plate through the third distance adjustment component to change the width of the storage cavity to accommodate the tail material of strips with different widths. S4. Empty Disk Recycling: After receiving the material, the robotic arm will pick up the remaining empty disk and transfer it to the empty disk recycling mechanism for collection, thus completing the entire fully automatic material receiving cycle.
[0089] In this invention, material picking and shaping are completed simultaneously at the same workstation in step S1, which greatly shortens the auxiliary time; in step S3, a gradient interlocking cutting method is adopted to ensure that the splicing ends are absolutely flush; the overall method logic achieves parallel and efficient operation by ensuring that the material loading and unloading system of the robotic arm and the material conveying and shaping mechanism do not interfere with each other, which greatly improves the material change cycle of the SMT production line.
[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
