Description

Technical Field

[0001] This utility model relates to the field of electronic component soldering technology, specifically a rotary soldering machine. Background Technology

[0002] Traditional soldering equipment mostly adopts a single-station or linear multi-station structure. Single-station soldering requires the sequential completion of the feeding, positioning, soldering, and unloading processes. There is waiting time between each step, resulting in low operating efficiency and difficulty in meeting the needs of mass production. Although linear multi-station can achieve multiple processes in parallel, it is limited by the transmission path, and there are start-stop gaps in material transmission. In addition, the equipment occupies a large space, limiting its adaptability.

[0003] Existing technologies commonly suffer from the problem that interruptions in material transport prevent continuous soldering operations, thereby affecting production efficiency and increasing the processing cost per unit product. Therefore, we need to provide a rotary soldering machine. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary soldering machine that achieves simultaneous loading, soldering, and unloading of multiple processes through a rotary circulating design. The positioning mechanism stably clamps the material through abutment parts and rotates smoothly with the rotary table, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary soldering machine, comprising: The base platform has a top seat with a cabinet door fixedly installed on top. A tray for placing materials is rotatably installed on the top of the base platform. A drive unit for rotating the tray is installed inside the base platform via a bracket. The positioning mechanism, arranged in a ring array on the top of the disc, is used to clamp and fix multiple materials. The soldering mechanism is fixed to the top of the base platform by a bracket, and an assembly frame is mounted on the top of the bracket via a drive platform. The drive platform is used to adjust the position of the assembly frame.

[0008] Preferably, the frame includes a slide rod, a sleeve, and a connecting plate. Two slide rods are fixedly installed between the two connecting plates, and a sleeve is movably sleeved on the surface of each slide rod. Both sleeves are fixed inside the abutment block. The spring is movably sleeved on the surface of the slide rod, with one end fixed to the surface of the sleeve and the other end fixed to the surface of the connecting plate. One of the connecting plates is fixed to the surface of the tooling table.

[0009] Preferably, each of the multiple tooling tables is provided with a vertical plate below it. The bottom of the vertical plate is fixedly installed on the top of the base table by bolts. A sensing part is provided on the top of one side of the base table. A sensing rod is slidably installed on the top of the sensing part. The upper end of the sensing rod passes through the top of the body and is located inside the tooling table.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: a rotary soldering machine, comprising: The base platform 1 has a top seat 2 with a cabinet door fixedly installed on top. A tray 3 for placing materials is rotatably installed on the top of the base platform 1. A drive unit 4 for rotating the tray 3 is installed inside the base platform 1 through a bracket 61. Positioning mechanism 5, in a ring array on top of the disc 3, is used to clamp and fix multiple materials; The soldering mechanism 6 is fixed to the top of the base platform 1 by the bracket 61, and the top of the bracket 61 is equipped with an assembly frame 63 via the drive platform 62. The drive platform 62 is used to adjust the position of the assembly frame 63. A soldering gun 64 is fixedly installed on the surface of the assembly frame 63. A feeding rack 65 for installing soldering wire is also provided on one side of the assembly frame 63. Specifically, the rotary circulating design enables simultaneous loading, soldering, and unloading of multiple processes, completely breaking the limitations of traditional single-station intermittent operation and reducing waiting time between processes. The positioning mechanism 5 stably clamps the material through the contact part 53, and works with the rotary table to rotate smoothly, ensuring the positioning accuracy of the material at the soldering station and avoiding soldering deviation caused by material displacement. In addition, the continuous operation mode reduces the impact of equipment start-up and shutdown on the temperature stability of the soldering gun 64, further improving soldering consistency.

[0018] like Figure 2 As shown, the positioning mechanism 5 includes a tooling table 51 fixed to the top of the disc body 3 by bolts. The top of the tooling table 51 is provided with an embedding groove 52 for placing materials. The positioning mechanism 5 is detachably connected to the disc body 3 through the tooling table 51. The tooling table 51 is made of high-strength aluminum alloy material. It is fastened to the threaded hole on the top of the disc body 3 by countersunk bolts through the pre-set through hole at the bottom of the tooling table 51, ensuring a stable connection and facilitating subsequent disassembly and replacement. The side of the tooling table 51 is provided with an abutting member 53 for abutting the material in the embedding groove 52. Specifically, the embedding groove 52 on the top of the tooling table 51 adopts a contoured structure that adapts to the shape of the material. The abutment 53 is fixed to the adjacent two sides of the tooling table 51 by bolts. Its installation height is precisely matched with the clamping force point of the material in the embedding groove 52, ensuring that the abutment block 532 can effectively abut against the material. In coordination with the feeding mechanism 11, when the feeding gripper 112 places the material, the abutment 53 temporarily avoids and then quickly resets and clamps.

[0019] like Figure 7 As shown, two frames 531 are symmetrically installed on adjacent sides of the tooling table 51. An abutment block 532 is installed inside the frame 531 by means of a spring 533. The frame 531 is fastened to the side of the tooling table 51 by bolts through a connecting plate 5313. The abutment block 532 is movably connected to the slide rod 5311 inside the frame 531 by means of a sleeve 5312. The spring 533 is sleeved on the outside of the slide rod 5311 to form an elastic telescopic structure. The protrusion on the surface of the abutment block 532 abuts against the surface of the material. When material is placed in or removed, an external force (such as the electric push rod of the feeding gripper 112) pushes the contact block 532, causing the sleeve 5312 to slide axially along the slide rod 5311 and compress the spring 533. After the external force disappears, the spring 533 elastically returns to its original position, causing the contact block 532 to slide in the opposite direction along the slide rod 5311 until the protrusion on the surface of the contact block 532 tightly abuts against the surface of the material, forming an elastic clamping action. The protrusion of the contact block 532 is made of wear-resistant engineering plastic to prevent scratching the surface of the material during clamping.

[0020] like Figure 7As shown, the frame 531 includes a slide rod 5311, a sleeve 5312, and a connecting plate 5313. Two slide rods 5311 are fixedly installed between the two connecting plates 5313, and sleeves 5312 are movably sleeved on the surfaces of the two slide rods 5311. The two connecting plates 5313 are arranged in parallel. The two ends of the slide rods 5311 are fixed to the connecting plates 5313 by welding or threaded connection to form a stable frame structure. The two sleeves 5312 are fixed inside the abutment block 532. The spring 533 is movably sleeved on the surface of the slide rod 5311, with one end fixed to the surface of the sleeve 5312 and the other end fixed to the surface of the connecting plate 5313. One of the connecting plates 5313 is fixed to the surface of the tooling table 51. Specifically, the slide bar 5311 is made of stainless steel and its surface is polished to reduce sliding friction with the sleeve 5312. When the abutment block 532 is subjected to force, the two sleeves 5312 slide synchronously along the corresponding slide bar 5311, and the spring 533 is compressed to store elastic potential energy. After the external force is removed, the spring 533 releases its potential energy to push the sleeve 5312 to reset the abutment block 532.

[0021] like Figure 8 As shown, each of the multiple tooling tables 51 is provided with a vertical plate 7. The bottom of the vertical plate 7 is fixedly installed on the top of the base table 1 by bolts. The top of the vertical plate 7 is separated from the bottom of the disc body 3, and the bottom is fixed to the top of the base table 1 by bolts to form a fixed support. The base platform 1 has a sensing part 8 on one side of the top. A sensing rod is slidably installed on the top of the sensing part 8. The upper end of the sensing rod passes through the top of the body and is located inside the tooling table 51. When materials are placed in the tooling table 51, the materials squeeze the sensing rod, which identifies that there are materials in the tooling table 51. When the plate 3 needs to be rotated, the sensing rod moves down without affecting the rotation of the plate 3. Specifically, when material is placed in the fixture 51, the weight of the material or the pressure applied during placement compresses the top of the sensing rod, causing it to slide downwards and triggering the sensor inside the sensing unit 8 to identify the presence of material at that station. When the disc 3 is about to rotate, the sensing unit 8 drives the sensing rod to move further downwards, ensuring its top is below the bottom of the fixture 51 to avoid interference with the rotation of the disc 3. After rotating to the correct position, the sensing rod resets and remains ready. The sensing unit 8 uses an existing proximity sensor module to achieve accurate identification of the material's presence.

[0022] like Figure 6 As shown, both the tooling table 51 and the disk body 3 have reserved holes 9 for inserting the sensing rod. The hole diameter is slightly larger than the diameter of the sensing rod to ensure that the sensing rod slides smoothly. The disk body 3 has a ring array of hollow grooves 10. Furthermore, the inner wall of the reserved hole 9 is smoothed to reduce the frictional resistance when the sensing rod slides; the hollow groove 10 adopts a rectangular or arc-shaped structure, which not only reduces the overall weight of the disk 3 and the load on the drive unit 4, but also facilitates observation of the bottom status of the tooling table 51 and cleaning of solder residue.

[0023] like Figure 2 As shown, the feeding conveyor belt 111 is fixed to the top edge of the base platform 1 by the bracket 61, and its discharge end is precisely aligned with the tooling table 51 of the loading station. The loading gripper 112 is installed on the top of the base platform 1 by the gantry or cantilever bracket 61, located between the feeding conveyor belt 111 and the loading station. The top of the base platform 1 is provided with a loading gripper 112 that grabs the material in the feeding conveyor belt 111 onto the tooling table 51. The feeding conveyor belt 111 adopts a belt conveyor structure with anti-slip textures or positioning protrusions on the surface to ensure that the material does not deviate during the conveying process. The loading gripper 112 operates according to a preset program. After grabbing the material from the feeding conveyor belt 111, it moves to the top of the tooling table 51 and pushes the abutment block 532 with an electric push rod to avoid it, so that the material is accurately placed into the embedding groove 52. Then the electric push rod resets and the abutment block 532 automatically clamps the material.

[0024] like Figure 2 As shown, the unloading conveyor belt 121 is fixed to the top of the base platform 1 by the bracket 61, and its feeding end corresponds to the tooling table 51 of the unloading station. The unloading mechanism 12 includes the unloading conveyor belt 121 fixed to the top of the base platform 1, and the top of the base platform 1 is also provided with an unloading gripper 122, which is used to grip the unloaded welding material in the tooling table 51 to the unloading conveyor belt 121. In this process, after the soldered material is transferred to the unloading station along with the tray 3, the sensing unit 8 sends a signal indicating that the material is complete. The unloading gripper 122 then moves to precisely grab the finished product in the tooling table 51. At the same time, its auxiliary push rod pushes the abutment block 532 to avoid the abutment block, making it easier to remove the finished product. The finished product is then placed on the unloading conveyor belt 121 and transported by the conveyor belt to the subsequent process.

[0025] It should be noted that the above electrical components are all existing technology products. They are selected, installed and debugged by those skilled in the art according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. The applicant does not impose any specific restrictions here.

[0026] After the device is started, the drive unit 4 drives the plate 3 on the top of the base platform 1 to rotate smoothly and at a constant speed. The positioning mechanism 5 on the top of the plate 3 in a ring array rotates synchronously with the plate 3. The feeding mechanism 11 grabs the material on the feeding conveyor belt 111 through the feeding gripper 112 and puts it into the tooling table 51 of the initial station. The feeding gripper 112 is provided with an electric push rod that pushes two abutment blocks 532 on the surface of the tooling table 51. Before the material is put into the tooling table 51, the electric push rod can push the two abutment blocks 532 outward at the same time to reserve space for the placement of the material. After the material is placed into the tooling table 51, the abutment member 53 on the side of the tooling table 51 drives the abutment block 532 through the spring 533 to stably clamp the material in the embedding groove 52. At the same time, the material squeezes the sensing rod, and the sensing unit 8 recognizes that there is material in the station and sends a feedback signal. Between the rotating disks 3, the sensing unit 8 retracts. When the tooling table 51 carrying the material rotates with the turntable to the soldering station, the drive table 62 adjusts the position of the assembly frame 63 so that the welding gun 64 is aligned with the part of the material to be soldered. The feeding rack 65 simultaneously feeds the welding wire to complete the soldering operation. After the soldering is completed, the turntable continues to rotate, and the finished product flows with the tooling table 51 to the unloading station. The unloading gripper 122 grabs the finished product to the unloading conveyor belt 121. At the same time, the loading station continuously loads new materials to achieve uninterrupted cyclic soldering.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
