Description

Technical Field

[0001] This utility model relates to the field of wave soldering, and in particular to a fully automatic wave soldering device. Background Technology

[0002] Wave soldering is a soldering process in which molten solder (usually a tin-lead alloy) is sprayed into a solder wave as required by a design using an electric or electromagnetic pump. The workpiece, which is pre-loaded with electronic components, passes through the solder wave to achieve a mechanical and electrical connection between the solder ends or leads of the components and the workpiece pads.

[0003] In existing production processes, wave soldering often requires the use of flux spraying equipment. The flux spraying station and the wave soldering station are often set up separately, with workpieces transported manually in between. This results in low automation, low efficiency, and a large footprint. Utility Model Content

[0004] To overcome the above problems, this utility model provides a fully automatic wave soldering machine. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0005] A fully automatic wave soldering device includes a worktable with a feeding conveyor and an unloading conveyor. A gripping and conveying mechanism is located at the end of the feeding conveyor, and a rotary feeding mechanism is located next to it. The rotary feeding mechanism includes a rotary table with a fixed base. A flux application mechanism, a wave soldering mechanism, and a robot are sequentially arranged around the rotary feeding mechanism. All three mechanisms—feeding conveyor, gripping and conveying mechanism, rotary feeding mechanism, flux application mechanism, wave soldering mechanism, and robot—are electrically connected to a central controller. After the workpiece is transported to the end of the feeding conveyor, the gripping and conveying mechanism grips the workpiece and moves it to the fixed base. The rotary table rotates to move the workpiece toward the flux application mechanism. After the flux application mechanism applies flux to the corresponding position on the workpiece, the rotary table rotates the workpiece toward the wave soldering mechanism. The robot grips the workpiece and performs wave soldering on the wave soldering mechanism, then transfers the workpiece to the unloading conveyor.

[0006] Furthermore, the feeding and conveying mechanism includes a feeding and conveying frame, on which a feeding motor and a feeding conveyor belt are installed. The feeding motor drives the feeding conveyor belt to rotate back and forth to convey the workpiece. At the end of the feeding and conveying frame, a first position sensor electrically connected to the central controller is also installed.

[0007] Furthermore, a blocking bracket is provided on the feeding conveyor, a blocking cylinder is provided on the blocking bracket, a blocking plate is provided on the movable end of the blocking cylinder, and a second positioning sensor is provided on the blocking bracket. The distance from the blocking bracket to the end of the feeding conveyor is greater than the width of the workpiece. The blocking cylinder drives the blocking plate to move onto the workpiece movement path to prevent the second workpiece from continuing to move towards the end of the feeding conveyor and to interfere with the first workpiece being clamped by the clamping and conveying mechanism.

[0008] Furthermore, the clamping and conveying mechanism includes a clamping fixed bracket, on which a transverse slide cylinder is mounted. A push cylinder is vertically mounted on the slide of the transverse slide cylinder, and a chuck cylinder is mounted on the movable end of the push cylinder. A fixed chuck is fixedly connected to one end of the chuck cylinder, and a movable chuck is fixedly connected to the movable end of the chuck cylinder. The transverse slide cylinder drives the push cylinder to move left and right, the push cylinder drives the chuck cylinder to move up and down, and the chuck cylinder drives the movable chuck to move back and forth to approach / move away from the fixed chuck, so as to complete the clamping and opening actions.

[0009] Furthermore, the rotary feeding mechanism also includes a rotary motor assembly, which is fixedly connected to the axis of the rotary table to drive the rotary table to rotate stably horizontally. Several fixed seats are provided on the rotary table, and the fixed seats are symmetrically arranged around the axis of the rotary table.

[0010] Furthermore, a limiting structure is provided on the fixed base to align and limit the workpiece.

[0011] Furthermore, the flux application mechanism includes a first motor and a front and rear slide module. The first motor drives the slide of the front and rear slide module to move back and forth. A second motor and a left and right slide module are arranged on the slide of the front and rear slide module. The second motor drives the slide of the left and right slide module to move left and right. A third motor and an upper and lower slide module are arranged on the slide of the left and right slide module. The third motor drives the slide of the upper and lower slide module to move up and down. An application head assembly is arranged on the slide of the upper and lower slide module.

[0012] Furthermore, the flux dispensing mechanism also includes a flux tank for storing flux, and the dispensing head assembly is connected to the flux tank.

[0013] Furthermore, position sensors are installed on the front and rear slide modules, the left and right slide modules, and the upper and lower slide modules. The position sensors are electrically connected to the central controller to control the movement position of the dotting head assembly.

[0014] Furthermore, the robotic arm includes grippers, with a positioning protrusion on the inner side of one side of the gripper and a positioning groove on one side wall of the workpiece. The positioning protrusion is aligned and inserted into the positioning groove so that the robotic arm can accurately align with the workpiece and stably grasp the workpiece.

[0015] The beneficial effects of this utility model are:

[0016] The device includes a worktable equipped with a feeding conveyor, a clamping and handling mechanism, a rotary feeding mechanism, a flux application mechanism, a wave soldering mechanism, a robotic arm, and an unloading conveyor. After the workpiece is transported to the end of the feeding conveyor, the clamping and handling mechanism clamps the workpiece and moves it to a fixed seat. The rotary table rotates to move the workpiece toward the flux application mechanism. After the flux application mechanism applies flux to the corresponding position on the workpiece, the rotary table rotates the workpiece toward the wave soldering mechanism. The robotic arm grips the workpiece and performs wave soldering on the wave soldering mechanism. Afterward, the workpiece is handed over to the unloading conveyor. This device can achieve fully automated feeding, flux application, wave soldering, and unloading, with high efficiency. Furthermore, all mechanisms are integrated on the worktable and operate around the rotary table, requiring minimal space. Attached Figure Description

[0037] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "fully automatic wave soldering device" of this utility model is provided in conjunction with the accompanying drawings.

[0038] See Figures 1-9In this embodiment, the fully automatic wave soldering device includes a worktable 100, on which are arranged a feeding and conveying mechanism 200, a clamping and transporting mechanism 300, a rotary feeding mechanism 400, a flux dispensing mechanism 500, a wave soldering mechanism 600, a robot arm 700, and an unloading and conveying mechanism 800. The clamping and transporting mechanism 300 is located at the end of the feeding and conveying mechanism 200, and the rotary feeding mechanism 400 is located beside the clamping and transporting mechanism 300. The rotary feeding mechanism 400 includes a rotary table 401, on which a fixed base 402 is provided. The flux dispensing mechanism 500, the wave soldering mechanism 600, and the robot arm 700 are arranged sequentially around the rotary feeding mechanism 400. The flux application mechanism 500, wave soldering mechanism 600, and robot 700 are all electrically connected to the central controller. After the workpiece 900 is transported to the end on the feeding conveyor, the clamping and handling mechanism 300 clamps the workpiece 900 and moves it to the fixed seat 402. The rotary table 401 rotates to move the workpiece 900 toward the flux application mechanism 500. After the flux application mechanism 500 applies flux to the corresponding position on the workpiece 900, the rotary table 401 continues to rotate the workpiece 900 toward the wave soldering mechanism 600. The robot 700 grabs the workpiece 900, flips it, and moves the area of ​​the workpiece 900 to be soldered toward the wave emitter port of the wave soldering mechanism 600. After the wave soldering is completed, the robot 700 transfers the workpiece 900 to the discharge conveyor 800 for transmission to the next process. This device achieves full automation of feeding, flux application, wave soldering, and discharging. The intermediate transfer workpieces 900 are all automated mechanically, improving production efficiency. Furthermore, the feeding and conveying mechanism 200, the clamping and handling mechanism 300, the flux application mechanism 500, the wave soldering mechanism 600, the robotic arm 700, and the discharging and conveying mechanism 800 are integrated on the worktable 100, and the layout design of the surrounding rotating feeding mechanism 400 reduces the footprint of the device.

[0039] See further Figure 3 In this embodiment, the feeding and conveying mechanism 200 includes a feeding and conveying frame 201, on which a feeding motor 202 and a feeding conveyor belt 203 are provided. The feeding motor 202 drives the feeding conveyor belt 203 to reciprocate to convey the workpiece 900. At the end of the feeding and conveying frame 201, a first position sensor 204 electrically connected to the central controller is also provided. After the first position sensor 204 senses that the workpiece 900 has been conveyed to the position, it will send a signal to the central controller. The central controller controls the clamping and conveying mechanism 300 to start clamping and conveying the workpiece 900.

[0040] More specifically, in this embodiment, a baffle bracket 205 is provided on the feeding conveyor 201, a baffle cylinder 206 is provided on the baffle bracket 205, a baffle plate 207 is fixedly connected to the movable end of the baffle cylinder 206, and a second positioning sensor 208 is provided on the baffle bracket 205. The distance from the baffle bracket 205 to the end of the feeding conveyor 201 is greater than the width of the workpiece 900. When the first positioning sensor 204 senses that the first workpiece 900 has not yet been clamped and moved away, and the second positioning sensor 208 senses that the second workpiece 900 has been transferred, the second positioning sensor 208 will send a signal to the central controller. The central controller controls the baffle cylinder 206 to drive the baffle plate 207 to move onto the moving path of the workpiece 900, so as to prevent the second workpiece 900 from continuing to move towards the end of the feeding conveyor 201 and thus interfere with the clamping and moving of the first workpiece 900 by the clamping and conveying mechanism 300.

[0041] See further Figure 4 In this embodiment, the clamping and transporting mechanism 300 includes a clamping fixed bracket 301, on which a transverse slide cylinder 302 is provided. A push cylinder 303 is vertically provided on the slide of the transverse slide cylinder 302. A chuck cylinder 304 is provided at the movable end of the push cylinder 303. A fixed chuck 305 is fixedly connected to one end of the chuck cylinder 304, and a movable chuck 306 is fixedly connected to the movable end of the chuck cylinder 304. The transverse slide cylinder 302 drives the push cylinder 303 to move left and right, the push cylinder 303 drives the chuck cylinder 304 to move up and down, and the chuck cylinder 304 drives the movable chuck 306 to move back and forth towards / away from the fixed chuck 305 to complete the clamping and unclamping actions. The transverse slide cylinder 302, the push cylinder 302, and the chuck cylinder 304 cooperate with each other to complete the action of clamping the workpiece and transporting it to the fixed seat 402.

[0042] See further Figure 5 In this embodiment, the rotary feeding mechanism 400 also includes a rotary motor assembly 403, which is fixedly connected to the axis of the rotary table 401 to drive the rotary table 401 to rotate horizontally in a stable manner. The rotary table 401 is provided with four fixed seats 402, which are symmetrically arranged around the axis of the rotary table 401. This ensures that there is always a workpiece 900 on the rotary table 401. When a workpiece 900 is being wave soldered, there is also a workpiece being spot coated with flux, which can improve production efficiency.

[0043] It should be noted that a limiting structure is provided on the fixed base 402 to align and limit the workpiece 900, preventing it from shifting during the horizontal rotation of the rotary table 401, which would affect the wave soldering quality of the product. In this embodiment, the limiting structure is a protruding limiting post on the fixed base 402, with a corresponding limiting hole at the bottom of the workpiece 900. The limiting post passes through the limiting hole, completing the alignment and fixing of the workpiece 900 and the fixed base 402. Of course, in other embodiments, the limiting structure can also be a recessed groove on the fixed base 402, the shape of which matches the bottom of the workpiece 900. The workpiece 900 sits in the groove, completing the alignment and fixing of the workpiece 900 and the fixed base 402.

[0044] See further Figure 6 and Figure 7 In this embodiment, the flux application mechanism 500 includes a first motor 501 and a front and rear slide module 502. The first motor 501 drives the slide of the front and rear slide module 502 to move back and forth. A second motor 503 and a left and right slide module 504 are provided on the slide of the front and rear slide module 502. The second motor 503 drives the slide of the left and right slide module 504 to move left and right. A third motor 505 and an upper and lower slide module 506 are provided on the slide of the left and right slide module 504. The third motor 505 drives the slide of the upper and lower slide module 506 to move up and down. A flux application head assembly 507 is provided on the slide of the upper and lower slide module 506. The first motor 501, the second motor 503, and the third motor 505 are all electrically connected to the central controller. Position sensors 509 are also installed on the front and rear slide modules 502, the left and right slide modules 504, and the upper and lower slide modules 506, and these position sensors 509 are all electrically connected to the central controller. The position sensors 509 transmit the position information of each slide and the application head assembly 509 to the central controller. After calculation, the central controller controls the movement of the first motor 501, the second motor 503, and the third motor 505, thereby precisely controlling the position of the application head assembly 509 to apply flux, ensuring the accuracy of the application.

[0045] More specifically, in this embodiment, the flux dispensing mechanism 500 also includes a flux tank 508 for storing flux. The flux tank 508 is disposed in the front and rear slide modules 5021. The dispensing head assembly 507 is connected to the flux tank 508 and serves as an external expansion component of the dispensing head assembly 507 to increase the flux capacity.

[0046] See further Figure 8 and Figure 9In this embodiment, the robotic arm 700 includes a gripper 701. A positioning protrusion 702 is provided on the inner side of one side of the gripper 701, and a positioning groove 901 is provided on one side wall of the workpiece 900. The positioning protrusion 702 is aligned and inserted into the positioning groove 901. This not only prevents mistaken identity but also ensures that the robotic arm 700 is accurately aligned with the workpiece 900 and can stably grip the workpiece 900.

[0047] It should be noted that in this embodiment, the bottom of the workbench 100 is equipped with feet and rollers. When the feet are removed, the rollers can be placed on the ground, facilitating the transfer of the entire wave soldering device. In addition, a protective cover (not shown) can be installed on the workbench 100. The protective cover covers all the above-mentioned mechanisms, providing isolation and protection. The protective cover can also be equipped with windows that can be opened and closed, allowing staff to inspect the internal mechanisms. An alarm (not shown) can also be installed on the protective cover. The alarm is electrically connected to the central controller. When a malfunction occurs in the device, the alarm will sound an alarm to remind staff to perform maintenance.
