Description

Technical Field

[0001] This utility model relates to an assembly machine, specifically to an assembly machine for a network transformer. Background Technology

[0002] Network transformers, as key electronic components in communication equipment, have a compact structure but a precise internal construction, especially in the pin connections, where extremely high assembly precision is required. Traditional network transformer assembly processes typically involve step-by-step manual operations, including the insertion of upper and lower pin holders, the crimping of the top cover, laser marking, and the uniform cutting of pin lengths—multiple independent steps. Each step requires manual or semi-automatic transfer of the semi-finished product to the next workstation, increasing labor costs and significantly lengthening the overall production cycle.

[0003] The insertion step of the upper and lower needle holders is particularly critical in the above process. Since the upper needle holder typically has dozens of fine metal pins, these pins must be inserted accurately into the corresponding pin holes on the lower needle holder. Any slight deviation can cause misalignment of the pins and pin holes, leading to bending, deformation, or even breakage of the pins, severely affecting the electrical performance and yield rate of the product. To avoid this problem, most manufacturers still rely on manual operation, with workers manually aligning the upper and lower needle holders before pressing them together. While this method reduces the risk of pin damage to some extent, it is extremely inefficient, requires a high level of skill from the operators, and prolonged operation can easily lead to fatigue, increasing the probability of misjudgment and operational errors.

[0004] Therefore, it is necessary to design a network transformer assembly machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an assembly machine for network transformers that can effectively accelerate the production cycle and improve production efficiency.

[0006] The technical solution of this utility model is: An assembly machine for a network transformer comprises a machine base, an indexing plate, mold bases, a lead cutter, a feeding mechanism, a lower needle seat feeding mechanism, an upper needle seat feeding and pressing mechanism, an upper cover feeding and pressing mechanism, and a laser marking device. The machine base is equipped with an indexing plate. The machine base is characterized by having mold bases evenly distributed in a circular pattern. The lead cutter, feeding mechanism, lower needle seat feeding mechanism, upper needle seat feeding and pressing mechanism, upper cover feeding and pressing mechanism, and laser marking device are sequentially arranged on the machine base at the edge of the indexing plate. The lower needle seat feeding mechanism, upper needle seat feeding and pressing mechanism, and upper cover feeding and pressing mechanism each comprise a vibrating feeder, a translation cylinder, a lifting cylinder, and a chuck. The chuck of the upper needle seat feeding and pressing mechanism is symmetrically equipped with straightening devices for straightening the upper needle seat needles.

[0007] A translation cylinder is installed above the linear vibrating feeder. A lifting cylinder is installed at the piston rod end of the translation cylinder, and a clamp is installed at the piston rod end of the lifting cylinder. The translation cylinder and the linear vibrating feeder are respectively fixedly connected to the machine base through a bracket.

[0008] The straightening device consists of an assembly block, a slider, a straightening plate, and a reset cylinder. The slider is movably mounted on the bottom of the assembly block via a slide rail, and a straightening plate is provided on the side of the slider on one side of the chuck. A strip-shaped hole is provided on the bottom end face of the slider, and a reset wheel is mounted on the end of the strip-shaped hole on one side of the chuck via a short shaft. A reset cylinder is provided on the assembly block, and the piston rod of the reset cylinder extends into the strip-shaped hole and is slidably connected to the reset wheel. The assembly block is fixedly connected to the chuck.

[0009] The straightening plate has inner straightening grooves evenly distributed on its side to straighten the inner layer of the needles, and outer straightening grooves to straighten the outer layer of the needles are provided between the inner straightening grooves.

[0010] The mold base is provided with a needle seat limiting groove in the middle, and a needle foot limiting groove is provided in parallel at the bottom of the needle seat limiting groove; a guide slope is provided on the mold base outside the needle foot limiting groove, and the guide slope is slidably connected to the slider.

[0011] The discharge mechanism consists of a transfer cylinder, a support plate, a lifting cylinder, and a clamp. The piston rod of the transfer cylinder is equipped with a long strip-shaped support plate, and the two ends of the support plate are respectively equipped with lifting cylinders. The piston rod of the lifting cylinder is equipped with a clamp. The transfer cylinder is fixedly connected to the machine base through a bracket.

[0012] The support plate is positioned above the cutter, with its inner end extending above the indexing plate, and an inclined receiving plate positioned on the machine base at the outer end of the support plate.

[0013] The beneficial effects of this utility model are as follows: This network transformer assembly machine, through a combination of an indexing plate, a lower needle seat feeding mechanism, an upper needle seat feeding and pressing mechanism, a top cover feeding and pressing mechanism, a laser marking device, a lead cutter, and a discharge mechanism, sequentially completes the processes of lower needle seat feeding, upper needle seat pressing, top cover pressing, marking, lead cutting, and discharge of the network transformer. This allows materials to circulate within the assembly machine, eliminating the need for manual material handling, effectively accelerating the production cycle, improving production efficiency, and reducing labor intensity. A straightening device aligns the needles of the upper needle seat, ensuring accurate insertion into the needle holes and preventing needle bending. Replacing manual calibration with this straightening device further improves production efficiency and reduces labor intensity. This solves the problem of low assembly efficiency inherent in traditional network transformer assembly methods. It is particularly suitable for assembling and using network transformers.

[0016] The assembly machine for this network transformer consists of a machine base 1, an indexing plate 2, a mold base 3, a lead cutter 4, a discharge mechanism 5, a lower needle seat loading mechanism 6, an upper needle seat loading and pressing mechanism 7, an upper cover loading and pressing mechanism 8, and a laser marking device 9. The machine base 1 is equipped with an indexing plate 2 (KTLA-6-300 type), on which mold bases 3 are evenly distributed in a circular pattern. The indexing plate 2 drives the mold bases 3 to rotate, which in turn drives the workpieces loaded onto the mold bases 3 to rotate. Through the rotation of the workpieces, they flow between various processes, thereby sequentially performing lower needle seat loading, upper needle seat pressing, upper cover pressing, marking, lead cutting, and discharge, accelerating the production cycle and improving production efficiency. On the machine base 1 at the edge of the indexing plate 2, there are sequentially arranged a needle cutter 4 (HY-S01 model of Huiyue Technology) for cutting needles to make them neat, a feeding mechanism 5 for unloading assembled workpieces, a lower needle seat feeding mechanism 6 for feeding the lower needle seat, an upper needle seat feeding and pressing mechanism 7 for feeding the upper needle seat and pressing it into the lower needle seat, an upper cover feeding and pressing mechanism 8 for feeding the upper cover and pressing it into the lower needle seat, and a laser marking machine 9 (30W fiber laser marking machine) for marking the top of the upper cover.

[0017] The lower needle seat feeding mechanism 6, the upper needle seat feeding and pressing mechanism 7, and the upper cover feeding and pressing mechanism 8 each consist of a vibrating feeder 601, a translation cylinder 602, a lifting cylinder 603, and a chuck 604. The translation cylinder 602 is positioned above the vibrating feeder 601 (CR100 type). The lifting cylinder 603 is located at the piston rod end of the translation cylinder 602, and the chuck 604 (HFCX16 type four-jaw manipulator) is located at the piston rod end of the lifting cylinder 603. The translation cylinder 602 and the vibrating feeder 601 are fixedly connected to the machine base 1 via brackets. The function of the vibrating feeder 601 is to convey the lower needle seats, upper needle seats, or upper covers arranged sequentially on the material plate of the vibrating feeder 601 towards one side of the indexing plate 2, thereby feeding them one by one. The function of the translation cylinder 602 is to drive the lifting cylinder 603 to move between the linear vibrating feeder 601 and the indexing plate 2, thereby driving the chuck 604 between the linear vibrating feeder 601 and the indexing plate 2, thus transferring the lower needle seat, upper needle seat or upper cover on the linear vibrating feeder 601 to the indexing plate 2.

[0018] The upper needle holder feeding and pressing mechanism 7 has symmetrically arranged straightening devices on the chuck 604 to straighten the needle feet of the upper needle holder. The straightening device consists of an assembly block 701, a slider 702, a straightening plate 703, and a reset cylinder 704. The slider 702 is movably mounted on the bottom of the assembly block 701 via a slide rail, and the straightening plate 703 is arranged on the side of the slider 702 on one side of the chuck 604. The straightening plate 703 has inner straightening grooves 707 evenly distributed on its side to straighten the inner needle feet, and outer straightening grooves 708 are arranged between the inner straightening grooves 707 to straighten the outer needle feet. The function of the straightening plate 703 is to straighten and limit the needle feet through the inner straightening grooves 707 and the outer straightening grooves 708, respectively, so that the needle feet are not easily deviated during the insertion of the needle hole, thereby ensuring that the needle feet can be accurately inserted into the needle hole and ensuring the normal assembly of the upper and lower needle holders.

[0019] A strip-shaped hole 705 is provided on the bottom end face of the slider 702. A reset wheel 706 is mounted on the end of the strip-shaped hole 705 on one side of the chuck 604 via a short shaft. A reset cylinder 704 is provided on the assembly block 701. The piston rod of the reset cylinder 704 extends into the strip-shaped hole 705 and is slidably connected to the reset wheel 706. The assembly block 701 is fixedly connected to the chuck 604. The function of the reset cylinder 704 is to press the reset wheel 706 downward by the piston rod of the reset cylinder 704, which in turn pushes the slider 702 to slide towards the chuck 604, thereby pushing the straightening plate 703 inward to straighten and limit the needle.

[0020] A needle seat limiting groove 301 is provided in the middle of the mold base 3 to limit the lower needle seat. A needle foot limiting groove 302 is provided parallel to the bottom of the needle seat limiting groove 301 to allow the needle foot to pass through and to limit the needle foot, further restricting the position of the lower needle seat. A guide slope 303 is provided on the mold base 3 outside the needle foot limiting groove 302, and the guide slope 303 is slidably connected to the slider 702. The function of the guide slope 303 is to push the slider 702 outward by sliding relative to it, thereby driving the straightening plate 703 outward. When the upper and lower needle seats are pressed together after the needle foot is inserted into the needle hole, the straightening plate 703 is moved away, allowing the upper and lower needle seats to be pressed together normally.

[0021] The discharge mechanism 5 consists of a transfer cylinder 501, a support plate 502, a lifting cylinder 603, and a chuck 604. A long strip-shaped support plate 502 is mounted on the piston rod of the transfer cylinder 501. Lifting cylinders 603 are mounted on both ends of the support plate 502, and chucks 604 are mounted on the piston rods of the lifting cylinders 603. The transfer cylinder 501 is fixedly connected to the machine base 1 via a bracket. The support plate 502 is positioned above the cutter 4, with its inner end extending above the indexing plate 2. An inclined receiving plate 10 is mounted on the machine base 1 at the outer end of the support plate 502. The function of the transfer cylinder 501 is to drive the support plate 502 to move between the indexing plate 2, the cutter 4, and the inclined receiving plate 10, thereby driving the lifting cylinders 603 at both ends of the support plate 502 and the chuck 604 to move between the indexing plate 2, the cutter 4, and the inclined receiving plate 10, thus transferring the assembled network transformer between the three.

[0022] When the assembly machine for the network transformer is working, the lower needle seats are sequentially arranged on the vibrating feeder 601 of the lower needle seat feeding mechanism 6, the upper needle seats are sequentially arranged on the vibrating feeder 601 of the upper needle seat feeding and pressing mechanism 7, and the upper cover is sequentially arranged on the vibrating feeder 601 of the upper cover feeding and pressing mechanism 8. After the lower needle seats, upper needle seats, and upper cover are filled, the translation cylinder 602, lifting cylinder 603, and chuck 604 of the lower needle seat feeding mechanism 6 clamp the lower needle seats on the vibrating feeder 601 and transfer them to the mold base 3 of the indexing plate 2. After the lower needle seats are transferred to the mold base 3, the indexing plate 2 rotates, driving the mold base 3 and the lower needle seats on the mold base 3 to rotate towards the upper needle seat feeding and pressing mechanism. After the indexing plate 2 rotates to its position, the translation cylinder 602, lifting cylinder 603, and chuck 604 of the upper needle seat feeding and pressing mechanism 7 clamp the upper needle seat on the vibrating feeder 601 and transfer it above the lower needle seat. During the transfer of the upper needle seat, the reset cylinder 704 of the straightening device is activated. The reset cylinder 704, in conjunction with the reset wheel 706, pushes the slider 702 and the straightening plate 703 toward the chuck 604, so that the straightening plate 703 straightens and limits the needle of the upper needle seat through the inner straightening groove 707 and the outer straightening groove 708. After the upper needle seat moves above the lower needle seat, the lifting cylinder 603 drives the upper needle seat downward through the chuck 604, and under the straightening of the straightening plate 703, the needle is inserted into the needle hole. After the needle is inserted into the needle hole, the straightening device continues to descend, and under the action of the guide slope 303 of the mold base 3, it pushes the slider 702 and the straightening plate 703 of the straightening device to move outward, pulling the straightening plate 703 out from between the upper needle seat and the lower needle seat. After the upper needle seat and the lower needle seat are pressed into place, the indexing plate 2 drives the mold base 3 and the lower and upper needle seats pressed into place by the mold base 3 to move to the upper cover feeding and pressing mechanism. After the lower and upper needle seats are pressed into place, the translation cylinder 602, the lifting cylinder 603, and the chuck 604 of the upper cover feeding and pressing mechanism 8 clamp the upper cover on the direct vibration feeder 601 and transfer it above the upper needle seat. After the upper cover moves into place, the lifting cylinder 603 drives the upper cover to descend and press the upper cover onto the lower needle seat, completing the assembly. After the assembly is completed, the indexing plate 2 drives the assembled network transformer to move downward to the laser marking machine 9, and the laser marking machine 9 performs laser marking on the top of the upper cover. After marking is completed, the indexing plate 2 transfers the network transformer to one side of the discharge mechanism 5. After the indexing plate 2 rotates into position, the transfer cylinder 501 of the discharge mechanism drives the support plate 502 and the lifting cylinders 603 at both ends of the support plate 502, as well as the chuck 604, to transfer between the indexing plate 2, the lead cutter 4, and the inclined receiving plate 10, thereby clamping and transferring the assembled network transformer between the indexing plate 2, the lead cutter 4, and the inclined receiving plate 10. After the network transformer is transferred to the lead cutter 4, the lead cutter 4 cuts the needles to make the needles neat. After the network transformer is transferred to the inclined receiving plate 10, it slides towards the bottom of the inclined receiving plate 10 one by one under its own gravity, arranging itself on the inclined receiving plate 10.

[0023] This network transformer assembly machine, through a combination of an indexing plate, a lower needle seat feeding mechanism, an upper needle seat feeding and pressing mechanism, a top cover feeding and pressing mechanism, a laser marking device, a lead cutter, and a discharge mechanism, sequentially completes the processes of lower needle seat feeding, upper needle seat pressing, top cover pressing, marking, lead cutting, and discharge of the network transformer. This allows materials to circulate within the assembly machine, eliminating the need for manual material handling, effectively accelerating the production cycle, improving production efficiency, and reducing labor intensity. A straightening device aligns the needles of the upper needle seat, ensuring accurate insertion into the needle holes and preventing needle bending. Replacing manual calibration with this straightening device further improves production efficiency and reduces labor intensity. This solves the problem of low assembly efficiency inherent in traditional network transformer assembly methods. It is particularly suitable for assembling and using network transformers.
