Description

Technical Field

[0001] This invention relates to the field of pin component handling equipment, specifically to an automatic foam machine and its handling method. Background Technology

[0002] In the manufacturing and processing of electronic components, components with leads (such as capacitors, resistors, and diodes) require precise insertion of their leads into foam boards during packaging and transportation to secure them and prevent bending, damage, or wear and tear during transport. Currently, most foam insertion operations for leaded components in the industry are completed manually or with semi-automated equipment.

[0003] Manual operation methods suffer from low efficiency, high labor intensity, and low insertion accuracy. Manually combing the pins can easily result in pins being crooked or crossed, making it impossible to accurately insert the pins into the foam holes, or even causing the pins to bend and be damaged. At the same time, the consistency of manual material handling and resetting operations is poor, and it is easy to miss or misinsert the pins, which affects the quality of subsequent processing or packaging.

[0004] Most existing semi-automatic foam machines suffer from defects such as unreasonable structural design and limited functionality: some machines lack an effective pin sorting mechanism, making it impossible to accurately correct skewed or crossed pins, resulting in insufficient insertion accuracy; some machines have poor coordination between the lifting and foam carrying mechanisms, failing to achieve synchronous linkage of pin exposure, sorting, and foam insertion, making the operation process cumbersome and further affecting work efficiency; in addition, the material positioning structure of existing machines is not stable enough, and components are prone to shifting after being loaded, making foam positioning inconvenient, and components are prone to falling off during the unloading process, making it difficult to meet the needs of large-scale, high-precision production.

[0005] In view of the shortcomings of the existing technologies, there is an urgent need for an automatic foam machine and material handling method with reasonable structure, high degree of automation, high insertion accuracy and high operation efficiency, so as to solve the problems of many drawbacks of manual operation and insufficient performance of semi-automatic equipment in the existing technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide an automatic foam machine and a material handling method. This foam machine features a rational structural design and a high degree of automation, enabling fully automated operation of the entire process, including automatic feeding, lead sorting, foam insertion, and material handling of leaded components. This improves insertion accuracy and operational efficiency while reducing labor intensity. The material handling method has clear steps and strong coordination, ensuring the precision of lead sorting and foam insertion, preventing lead damage, and guaranteeing operational quality.

[0007] To solve the above-mentioned technical problems, the present invention achieves this through the following solution: An automatic foam machine of the present invention includes a frame, a platform disposed at the upper end of the frame, and further includes: A lifting section is installed on the platform, the lifting section having a ejector pin module and a first lifting mechanism drivenly connected to the ejector pin module; The material carrier is mounted on the frame and located directly above the ejector pin module, and has a mesh array for the pin components to rise. A pin combing mechanism has a first power unit and a comb tooth unit. The first power unit has a second lifting mechanism and a horizontal driving unit driven by the second lifting mechanism. The horizontal driving unit and the comb tooth unit are driven by the horizontal driving unit. The horizontal driving unit drives the comb tooth unit to enter the upper area of ​​the material carrier unit in a preset direction, and drives the horizontal driving unit to rise and fall through the second lifting mechanism, thereby causing the horizontal driving unit to drive the comb tooth unit to rise and fall synchronously, so as to comb the pins of the pin components. The foam carrying mechanism has a foam positioning frame and a second power unit that is driven to the foam positioning frame. The second power unit drives the foam positioning frame to rise and fall. The foam positioning frame is located directly above the material carrying part.

[0008] Furthermore, the first lifting mechanism includes: The first cylinder module is mounted on the underside of the platform via a cylinder bracket; A cylinder adapter plate that is driven and connected to the first cylinder module; The ejector pin module includes: The perforated punch top plate, fixed to the cylinder adapter plate, has multiple punch fixing holes; Multiple punches are fixed in the punch fixing holes and are set one-to-one with the mesh array. The trajectory of the upper end of the multiple punches after rising can reach the mesh array.

[0009] Furthermore, the material-carrying section includes: A lower perforated plate is fixed to the platform. The upper part of the lower perforated plate has a raised layer, and a U-shaped frame is fixed to its side. The two ends of the opening of the U-shaped frame are folded outward to form an open structure. The height of the U-shaped frame is higher than that of the raised layer. A mesh plate is fixed to the convex layer, and a mesh array that runs vertically between the upper mesh plate and the lower mesh plate is formed.

[0010] Furthermore, the second lifting mechanism includes: A second cylinder module fixed to the lower surface of the platform; A lifting plate assembly connected to the drive end of the second cylinder module.

[0011] Furthermore, the lifting plate assembly is horizontally arranged, and double rows of guide rails are horizontally arranged on it; The power source of the horizontal drive unit is a linear cylinder. The cylinder shell of the linear cylinder is fixed to the lifting plate assembly, and its piston shaft drives the comb tooth part. The front end of the comb tooth part is a combing needle arranged in a linear array to form a comb tooth shape.

[0012] Furthermore, the upper surface of the platform is fixed with a first upright plate and a second upright plate arranged at a certain distance, and the front sides of the first upright plate and the second upright plate are provided with vertically arranged double rows of vertical rails. The second power unit includes: A pulley assembly vertically mounted on the first upright plate; The lifting beam module has one end slidably connected to the double-row vertical rails of the second upright plate, and the other end fixed to the pulley group and slidably connected to the double-row vertical rails of the first upright plate. The foam positioning frame is installed on the lifting beam module. A servo motor with a reduction gear is mounted on the lower surface of the platform and is driven by the active end of the pulley assembly.

[0013] Furthermore, the foam positioning frame is a side-sliding positioning structure with an open surface at its lower end, which is located directly above the material loading section.

[0014] The present invention discloses a material handling method for an automatic foam machine, the method being applied to the automatic foam machine, the material handling method comprising the following steps: S1. Punch plug positioning and feeding: The initial position of the punch is set at the lower opening of the mesh array, so that the punch blocks the bottom of the mesh array to form a plug structure; the pin-type components with leads fall into the through mesh array and are stably supported by the top of the punch. At this time, all the leads of the pin-type components are housed inside the mesh array, with no leads exposed. Slide the foam board into the foam positioning frame; The initial position of the comb teeth is in the rear area of ​​the U-shaped frame and is higher than the U-shaped frame; S2. Punch lifting and pin orientation exposure: The first lifting mechanism of the lifting section is activated. The first cylinder module drives multiple punches to rise vertically in sync through the cylinder adapter plate and the mesh punch top plate. The punches push the pin components supported at the bottom to move upward along the mesh array, so that the pins of the pin components pass through the upper port of the mesh array and are exposed at a preset neat height, in preparation for pin sorting. S3. Horizontal insertion of comb teeth and pin gap combing: The horizontal drive unit of the pin combing mechanism is activated, and the linear cylinder drives the comb tooth part to move horizontally forward along the double-row guide rail, so that the combing needles at the front end of the comb tooth part are accurately inserted into the pin gap of adjacent pin components, correcting pin skew and crossing posture, and standardizing the pin arrangement spacing. S4. Coordinated positioning and foam bonding preparation: Start the second power unit of the foam bearing mechanism. The servo motor drives the lifting beam module and foam positioning frame to descend vertically through the pulley group until the lower end face of the foam is about to reach the pin tip of the pin component. At this time, the second lifting mechanism of the pin combing mechanism is activated, and the lifting plate assembly and comb tooth section are driven to rise synchronously to the preset working height through the second cylinder module. While the comb tooth section rises, it combs and straightens the pins of each pin component. S5. Synchronous descent and pin insertion: Control the comb teeth and foam positioning frame to descend vertically in sync. The foam squeezes the pins of the components, so that the pins are precisely inserted into the foam to a preset depth along the guide of the combing needle. The combing needle limits the pin posture throughout the process to avoid pin deviation. S6. Comb teeth horizontal retraction and needle removal separation: After the pin is inserted into the foam, the comb teeth stop descending vertically, and the foam positioning frame remains stationary and locked; the linear cylinder is started to rotate in the reverse direction, driving the comb teeth to move horizontally backward, so that the combing needles completely exit the pin gap of the pin components. S7. Pressurization and foam lifting: After the comb tooth section is fully retracted, the foam positioning frame continues to descend slightly, applying constant and gentle pressure to the foam, compacting the insertion structure between the pins and the foam, and consolidating the alignment effect; then the second power unit reverses its rotation, driving the foam positioning frame to rise vertically, and simultaneously lifting the foam and the fixed pin components to the material picking station. S8. Unloading and Resetting the Machine: Remove the foam carrying the leaded components from the side-sliding foam positioning frame to complete the unloading operation; control the lifting part, lead combing mechanism and foam carrying mechanism to reset to the initial position in sequence, and the punch falls back to the lower end of the mesh array to re-form the plug, waiting for the next batch of material loading cycle.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention has a high degree of automation, realizing fully automated operation: This invention integrates the lifting section, the material loading section, the pin sorting mechanism, and the foam carrying mechanism, realizing the full automation of the pin component feeding, pin lifting and exposure, pin sorting, foam insertion, material picking, and whole machine reset. No manual intervention is required, which greatly reduces labor intensity, improves operation efficiency, and is suitable for large-scale production.

[0016] 2. The pin combing mechanism of this invention is precise and avoids pin damage: The pin combing mechanism adopts a horizontal drive and lifting drive coordinated design. The combing needles can be accurately inserted into the gap between adjacent pins, effectively correcting pin skew and crossing posture. In addition, the pins are limited throughout the foam insertion process to avoid pin offset and bending, ensuring pin integrity and insertion accuracy.

[0017] 3. The present invention has a reasonable structural design and strong synergy: the lifting part, the pin combing mechanism, and the foam carrying mechanism work together in a coordinated manner, and the punch lifting, comb combing, and foam descent and insertion are carried out simultaneously, optimizing the operation process and shortening the operation cycle; the material carrying part adopts upper and lower perforated plates to form a perforated array to achieve precise positioning of components, and the foam positioning frame adopts a side sliding structure to facilitate quick foam installation and removal and improve the convenience of operation.

[0018] 4. This invention offers precise positioning and high operational stability: the first and second lifting mechanisms are driven by cylinders, while the foam bearing mechanism is driven by a servo motor in conjunction with a pulley system, ensuring smooth driving and precise positioning; the double-row guide rails and double-row vertical rails enhance the stability of each mechanism's movement, prevent movement deviation, and guarantee operational consistency and reliability.

[0019] 5. The material handling method of this invention is scientific and efficient, with clear steps: The material handling method is designed according to the process of "positioning-lifting-combing-insertion-pin removal-compacting-part handling-resetting". Each step is smoothly connected and highly coordinated, which not only ensures the accuracy of pin combing and foam insertion, but also improves material handling efficiency. At the same time, the pressure compaction step consolidates the connection between the pin and the foam, preventing components from falling off during transportation. Attached Figure Description

The two ends of the opening of the U-shaped frame 7 are folded outward to form an open structure. The height of the U-shaped frame 7 is higher than the raised layer, which plays a protective and limiting role. The top mesh plate 22 is fixed to the raised layer. The mesh array 23 that runs through the upper and lower mesh plates 22 is formed between the top mesh plate 22 and the lower mesh plate 19. The lead components can fall into the mesh array to achieve precise positioning.

The horizontal driving unit drives the comb tooth unit 54 to enter the upper area of ​​the material carrier in a preset direction. The second lifting mechanism drives the horizontal driving unit to rise and fall, thereby driving the comb tooth unit 54 to rise and fall synchronously, achieving all-round combing of the pins. The second lifting mechanism includes a second cylinder. The module 56 and the lifting plate assembly 52 are used. The second cylinder module 56 is fixed to the lower surface of the platform 8. The lifting plate assembly 52 is connected to the drive end of the second cylinder module 56 and is set horizontally. The lifting plate assembly 52 is equipped with a double row of guide rails 53.

The foam positioning frame 6 is a side-sliding positioning structure. Its lower end is an open surface, which is located directly above the material loading part 2, which facilitates the quick installation and removal of foam and the accurate insertion of pins.

[0039] The first upright plate 12 and the second upright plate 16 of the foam support mechanism are equipped with a protective shell 3 for the foam support mechanism. The protective shell 3 is used to protect the components installed on the two upright plates. A touch-operable display screen is provided on the upper side of its front, and a three-color alarm light is provided on its top surface.

[0040] The frame 1 of the present invention is equipped with multiple casters and multiple foot cup brackets at the bottom. The casters facilitate the movement of the foam machine of the present invention, and the foot cup brackets can support the casters by rotating bolts to achieve positioning of the foam machine. Example 2:

[0041] Please refer to the appendix. Figure 8-12 The present invention discloses a material handling method for an automatic foam machine, applied to the automatic foam machine described in Example 1. This material handling method has clear steps and strong coordination, which can ensure operational accuracy and efficiency. Specifically, it includes the following steps: S1. Punch plug positioning and loading: The initial position of the punch 203 is set at the lower opening of the mesh array 23, so that the punch 203 blocks the bottom of the mesh array 23 to form a plug structure to prevent the pin components from falling off; the pin components 18 with pins are dropped into the through mesh array 23 and stably supported on the top of the punch 203. At this time, all the pins of the pin components 18 are housed inside the mesh array 23, with no pins exposed, to avoid premature damage to the pins; at the same time, the foam board 4 is slid into the foam positioning frame 6 to complete the foam positioning; the comb tooth part 54 is initially located in the rear area of ​​the U-shaped frame 7 and is higher than the U-shaped frame 7 to avoid affecting the loading and subsequent lifting operations.

[0042] S2. Punch lifting and pin orientation exposure: The first lifting mechanism of the lifting section 20 is activated, and the first cylinder module 201 is activated. Through the cylinder adapter plate 205 and the mesh punch top plate 204, multiple punches 203 are driven to rise vertically in sync. The punches 203 push the pin components 18 supported at the bottom to move upward along the mesh array 23, so that the pins of the pin components 18 pass through the upper port of the mesh array 23 and are exposed at a preset height. This height is preset according to the foam thickness and pin length to prepare for subsequent pin sorting.

[0043] S3. Horizontal insertion of comb teeth and pin gap combing: Start the horizontal drive unit of the pin combing mechanism 5. The linear cylinder 51 drives the comb tooth part 54 to move horizontally forward along the double-row guide rail 53, so that the combing needle 55 at the front end of the comb tooth part 54 is accurately inserted into the pin gap of the adjacent pin component 18. Through the limiting and guiding effect of the combing needle, the pin skew and cross posture are corrected, the pin arrangement spacing is regulated, and the pin can be accurately inserted into the foam hole.

[0044] S4. Coordinated positioning and foam bonding preparation: The second power unit of the foam bearing mechanism is activated. The servo motor 15 drives the lifting beam module 14 and the foam positioning frame 6 to descend vertically through the pulley group 9 until the lower end face of the foam 4 is about to reach the pin tip of the pin component 18. At this time, the foam and the pin maintain a preset distance to avoid premature contact that may cause pin offset. At the same time, the second lifting mechanism of the pin combing mechanism 5 is activated. The second cylinder module 56 drives the lifting plate assembly 52 and the comb tooth part 54 to rise synchronously to the preset working height. As the comb tooth part 54 rises, it further combs and straightens the pins of each pin component 18 to ensure that the pin posture is consistent.

[0045] S5. Synchronous descent and pin insertion: The control system controls the comb tooth section 54 and the foam positioning frame 6 to descend vertically in sync. The foam 4 gradually squeezes the pin of the pin component 18. Due to the guiding effect of the comb needle 55, the pin can be accurately inserted into the foam to a preset depth along the comb needle 55. The comb needle 55 limits the pin posture throughout the process to avoid pin offset and bending, and ensures insertion accuracy.

[0046] S6. Horizontal retraction of comb teeth and separation of pins: After the pins are inserted into the foam, the comb teeth 54 stops descending vertically, and the foam positioning frame 6 remains stationary and locked to prevent the foam and pins from shifting. Then, the linear cylinder 51 is activated to rotate in the opposite direction, driving the comb teeth 54 to move horizontally backward, so that the combing needles 55 completely exit the pin gap of the pin component 18, realizing the separation of the comb teeth from the pins and avoiding damage to the pins or foam when the combing needles exit.

[0047] S7. Pressurization and foam lifting: After the comb tooth section 54 is fully retracted, the foam positioning frame 6 continues to descend slightly, applying constant and gentle pressure to the foam, compacting the insertion structure between the pin and the foam, consolidating the alignment effect, and preventing the pin from falling out of the foam during subsequent transfer; after pressurization is completed, the second power unit reverses its rotation, driving the foam positioning frame 6 to rise vertically, and simultaneously lifting the foam 4 and the fixed pin components 18 to the material picking station, making it convenient for operators to pick up the materials.

[0048] S8. Unloading and Resetting the Machine: The operator removes the foam carrying the leaded components 18 from the side-sliding foam positioning frame 6, completing a single unloading operation. Then, the control system controls the lifting part 20, the lead combing mechanism 5, and the foam carrying mechanism to reset to their initial positions in sequence. The punch 203 falls back to the lower end of the mesh array 23 to re-form the plug, waiting for the next batch of material to be loaded, thus achieving continuous operation.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.

At this time, all the pins of the pin component (18) are stored inside the mesh array (23) and no pins are exposed. Slide the foam board (4) into the foam positioning frame (6); The comb teeth (54) are initially located in the rear area of ​​the U-shaped frame (7) and are higher than the U-shaped frame (7); S2. Punch lifting and pin orientation exposure: The first lifting mechanism of the lifting part (20) is activated. The first cylinder module (201) drives multiple punches (203) to rise vertically in sync through the cylinder adapter plate (205) and the mesh punch top plate (204). The punches (203) push the pin components (18) supported at the bottom to move upward along the mesh array (23), so that the pins of the pin components (18) pass through the upper port of the mesh array (23) and are exposed at a preset neat height, in preparation for pin sorting. S3. Horizontal insertion of comb teeth and pin gap combing: Start the horizontal drive of the pin combing mechanism (5), and the linear cylinder (51) drives the comb tooth part (54) to move horizontally forward along the double-row guide rail (53), so that the combing needle (55) at the front end of the comb tooth part (54) is precisely inserted into the pin gap of the adjacent pin component (18), correcting the pin skew and cross posture, and standardizing the pin arrangement spacing; S4. Coordinated positioning and foam bonding preparation: Start the second power unit of the foam bearing mechanism. The servo motor (15) drives the lifting beam module (14) and foam positioning frame (6) to descend vertically through the pulley group (9) until the lower end face of the foam (4) is about to reach the pin top of the pin component (18); At this time, the second lifting mechanism of the pin combing mechanism (5) is activated, and the lifting plate assembly (52) and the comb tooth part (54) are driven to rise synchronously to the preset working height through the second cylinder module (56). While the comb tooth part (54) rises, it combs and straightens the pins of each pin component (18). S5. Synchronous descent and pin insertion: Control the comb tooth part (54) and the foam positioning frame (6) to descend vertically in sync. The foam (4) squeezes the pin of the pin component (18) so that the pin is accurately inserted into the foam to a preset depth along the guide of the comb needle (55). The comb needle (55) limits the pin posture throughout the process to avoid pin deviation. S6. Comb teeth horizontal retraction and needle removal separation: After the pin is inserted into the foam, the comb teeth (54) stop descending vertically, and the foam positioning frame (6) remains stationary and locked; start the linear cylinder (51) to run in reverse, drive the comb teeth (54) to move horizontally backward, so that the combing needle (55) completely exits the pin gap of the pin component (18); S7. Pressurization and foam lifting: After the comb tooth section (54) is completely retracted, the foam positioning frame (6) continues to descend slightly, applying constant and gentle pressure to the foam, compacting the plug-in structure between the pin and the foam, and consolidating the alignment effect; then the second power unit reverses its operation, driving the foam positioning frame (6) to rise vertically, and driving the foam (4) and the fixed pin components (18) to rise synchronously to the material picking station; S8. Unloading and Resetting the Machine: Take out the foam carrying the pin components (18) from the side-sliding foam positioning frame (6) to complete the unloading operation; control the lifting part (20), the pin combing mechanism (5), and the foam carrying mechanism to reset to the initial position in sequence, and the punch (203) falls back to the lower end of the mesh array (23) to re-form the plug, waiting for the next batch of material loading cycle.
