Description

Technical Field

[0001] The present invention relates to the technical field of electronic component welding, and more particularly to an automatic welding device for electronic components of an integrated circuit board. Background Art

[0002] An integrated circuit board electronic component automatic soldering equipment is a highly automated machine system specifically designed for accurately, efficiently, and consistently soldering electronic components (including integrated circuit chips, resistors, capacitors, inductors, connectors, etc.) onto integrated circuit boards. These devices are core equipment in the modern electronics manufacturing industry, greatly improving production efficiency, soldering quality, and consistency, while reducing labor costs and error rates.

[0003] Deficiencies in existing technology: In traditional integrated circuit board insertion processes, there are widespread problems with insufficient position correction accuracy and limited adaptive adjustment capabilities. Relying on fixed fixtures or manual pre-adjustment, it is difficult to accurately calibrate the offset or tilt of the integrated circuit board during transportation, which can easily lead to component misalignment due to position deviation in the insertion machine, affecting welding reliability. In addition, the rigid clamping mechanism lacks a dynamic feedback mechanism, and the fixed clamping force can easily cause extrusion damage to the integrated circuit board, or incomplete correction due to incomplete fitting. There is a lack of targeted adjustment methods for the integrated circuit board, and manual intervention is required, reducing automation efficiency. Summary of the Invention

There are two gears, which are symmetrically arranged in the groove opened at the top of the side plate, and the two are fixedly connected by connecting rod 1. The middle part of connecting rod 1 is movably connected to a support, and the side of the support is fixedly connected to a pneumatic component.

The hydraulic cylinder 1 controls the lifting and lowering of the hanging frame fixedly connected to its bottom end through an internally movably connected telescopic rod 1. The bottom end of the hanging frame is fixedly connected to a slide groove, and a long groove is provided inside the slide groove. A motor is fixedly connected to the middle of the long groove.

[0017] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The automatic welding equipment for electronic components of an integrated circuit board involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained without creative work by ordinary technicians in this field fall within the scope of protection of the present invention.

[0018] Reference Figures 1 to 2 The present invention provides an automatic soldering device for electronic components of an integrated circuit board, comprising a second conveyor belt 1, above which a correction mechanism 2 and an automatic insertion machine 3 are sequentially arranged from the feed end. The correction mechanism 2 is used to adjust the position of an integrated circuit board 25 so that it is centered at the top end of the second conveyor belt 1. A first transfer robot 4 is provided on one side of the feed end of the second conveyor belt 1 for transferring the integrated circuit board 25 from the first conveyor belt 5 to the second conveyor belt 1. A second transfer robot 6 is provided on one side of the discharge end of the second conveyor belt 1 for transferring the integrated circuit board 25 from the second conveyor belt 1 to the seventh conveyor belt 7. A welding robot 8 is provided on one side of the seventh conveyor belt 7.

[0019] The welding robot 8 includes a mechanical cantilever and a welding module, and is also equipped with a machine vision module. The welding module is installed at the execution end of the mechanical cantilever. The execution path of the welding module is controlled by the mechanical cantilever. The machine vision module is integrated with the control module of the mechanical cantilever to accurately locate the welding position. It should be noted that the mechanical cantilever and the welding module both use currently known equipment. Since they are not the focus of the technical solution claimed to be protected by this application, they will not be described in detail.

[0020] Reference Figures 2 to 6 The correction mechanism 2 includes a longitudinal pushing assembly 21 and a vertical rod 22 installed on both sides of the second conveyor belt 1. The top end of the vertical rod 22 is fixedly connected to an adjustment assembly 23. The bottom end of the adjustment assembly 23 is fixedly connected to a symmetrically arranged fence 26. The two ends of the fence 26 are fixedly connected to a hydraulic cylinder 261. The hydraulic cylinder 261 is movably connected to a telescopic rod 262. The bottom of the opposite surface of the fence 26 is movably connected to a probe 263. The probe 263 is movably connected to the inner groove 264 opened at the bottom end of the fence 26 through a slide 265 fixedly connected at the end. The side of the slide 265 Terminal 1 267 is installed, and terminal 1 267 corresponds to terminal 2 268 installed on the inner wall of the inner groove 264, and a spring 266 is provided on the outer peripheral side of the probe 263, which is located between the slide plate 265 and the inner wall of the inner groove 264. The spring 266 is in a free state, and half of the probe 263 is inside the baffle 26 and half is outside the baffle 26. When the probe 263 is retracted by four-fifths, terminal 1 267 and terminal 2 268 are docked. The inside of the baffle 26 is provided with an electric circuit and a power supply. Terminal 2 268 at the end of the baffle 26 is electrically connected to the corresponding side hydraulic cylinder 2 261 through a wire.

[0021] During the movement of the side panels 26 toward the integrated circuit board 25, the screw rod 236 first contacts the edge of the integrated circuit board 25. When the edge of the integrated circuit board 25 is parallel to the edge of the side panels 26, all the probes 263 are synchronously retracted into the inner groove 264 until the terminal 1 267 at the end of the probe 263 docks with the terminal 2 268 installed on the inner wall of the inner groove 264. When the edge of the integrated circuit board 25 is not parallel to the edge of the side panels 26, the tilted integrated circuit board 25 will only press on the probe 263 at the end of the side panels 26, so that the corresponding terminal 1 267 docks with the terminal 2 268, and then the hydraulic cylinder 2 261 on the corresponding side is energized to control the telescopic rod 262 to extend to adjust the tilted integrated circuit board 25.

[0022] Reference Figure 3 and Figure 4The longitudinal pushing assembly 21 includes side plates 211 symmetrically arranged on both sides of the second conveyor belt 1. A groove is opened in the middle of the top of the side plate 211, and a group of symmetrically arranged mounting plates 212 and limit plates 213 are fixedly connected on both sides of the inner wall of the groove. The internal movably connected to the limit plate 213 is a rack 214. The bottom half of the rack 214 close to the limit plate 213 is smooth, and the bottom half close to the second conveyor belt 1 is fixedly connected with teeth. The teeth are engaged with gear 1 216. There are two gears 1 216, which are symmetrically arranged in the groove opened at the top of the side plate 211. The two are fixedly connected by a connecting rod 1 217. The middle part of the connecting rod 1 217 is movably connected to a support 218. The side of the support 218 is fixedly connected to a pneumatic component 219. In addition, the rack 214 is fixedly connected to a push plate 215 at one end close to the second conveyor belt 1.

[0023] Among them, the bottom end of the push plate 215 is in contact with and connected to the conveyor belt 24, and the conveyor belt 24 is at the same height as the upper plane of the second conveyor belt 1. The outer surface of the conveyor belt 24 is fixedly connected to a baffle 241, and the interior of the conveyor belt 24 is meshed with a gear 2 242. The interior of the gear 2 242 is fixedly connected with a connecting rod 2 243, and the end of the connecting rod 2 243 is movably connected to the side of the mounting plate 212. In addition, one end of the gear 2 242 is meshed with one end of the gear 1 216.

[0024] The integrated circuit board 1 25 moves in the direction of the feed end to the discharge end under the transmission of the second conveyor belt 1. When the edge of the integrated circuit board 1 25 contacts the baffle 241, a thrust is applied to the baffle 241, and the conveyor belt 24 rotates along with the movement of the integrated circuit board 1 25. At this time, the gear 2 242 is driven to rotate. The gears 2 242 on both sides of the second conveyor belt 1 are symmetrically arranged. The connecting rod 243 fixedly connects the two to ensure consistent operation. The rotation of the connecting rod 243 drives the gear 1 216 to rotate, and then drives the rack 214 to rotate. It slides in the direction close to the second conveyor belt 1. At this time, the racks 214 on both sides of the second conveyor belt 1 advance toward each other synchronously to ensure that the integrated circuit board 1 25 is located in the middle position of the second conveyor belt 1. After the racks 214 on both sides complete the centering adjustment of the integrated circuit board 1 25, the telescopic rod of the pneumatic component 219 contracts, and the meshing relationship between the gear 1 216 and the gear 2 242 is released through the support 218 and the connecting rod 1 217, and the rack 214 is driven to retract, stopping the advancement of the rack 214 and resetting it before the next cycle of the conveyor belt 24.

[0025] Reference Figure 5The top of the vertical rod 22 is fixedly connected to the horizontal rod 221, and the bottom end of the horizontal rod 221 is fixedly connected to the hydraulic cylinder 231. The hydraulic cylinder 231 is symmetrically arranged about the middle part of the horizontal rod 221. The hydraulic cylinder 231 controls the lifting and lowering of the hanging frame 233 fixedly connected at its bottom end through the internal movable telescopic rod 232. The bottom end of the hanging frame 233 is fixedly connected to a slide 234. A long groove is provided inside the slide 234. A motor 235 is fixedly connected to the middle of the long groove. A screw rod 236 with opposite threads at both ends is connected to the inside of the motor 235. Two sliders 237 are movably connected at both ends of the screw rod 236. The bottom ends of the slider 237 are fixedly connected to the guardrail 26.

[0026] When the integrated circuit board 25 moves to the bottom of the adjustment assembly 23, the hydraulic cylinder 231 controls the telescopic rod 232 to extend, so that the hanging frame 233 drives the fence 26 to descend through the slide 234 until the bottom surface of the fence 26 contacts the top surface of the second conveyor belt 1 and stops. At this time, the probe 263 has no contact with the integrated circuit board 25, and the motor 235 starts, and the control screw 236 rotates the control slider 237 to drive the fence 26 to move toward each other.

[0027] Reference Figure 7 , the motor 235 is electrically connected in parallel with the terminal 2 268 .

[0028] Reference Figures 5 to 7 The probes 263 are equidistantly arranged at the bottom of the side of the fence 26 . There are an even number of probes 263 . Each probe 263 corresponds to a group of terminal 1 267 and terminal 2 268 , and all the terminals 268 are electrically connected in series.

[0029] Among them, the electrical connection between the terminal 268 and the terminal 1 267 is recorded as 1, otherwise it is recorded as 0, and in the natural state, all 0s. When the probe 263 contacts the integrated circuit board 1 25, there are three connection situations: All 1: that is, the edge of the integrated circuit board 25 is parallel to the fence 26, the probe 263 is fully retracted so that the terminal 2 268 is connected to the terminal 1 267, and the motor 235 is powered off and stops running; There are 1 or 0: that is, the edge of the integrated circuit board 1 25 is not parallel to the fence 26, and the terminal 2 268 corresponding to the probe 263 at one end of the fence 26 is connected to the terminal 1 267. At this time, the motor 235 is powered off and stopped, and the hydraulic cylinder 2 261 on the docking side is started to control the telescopic rod 262 to be pushed out; All 0s: that is, the probe 263 does not contact the edge of the integrated circuit board 25, and the motor 235 is powered on and started.

[0030] Working principle of the present invention: The direction parallel to the moving direction of the second conveyor belt 1 is called the transverse direction, and the direction perpendicular to the moving direction of the second conveyor belt 1 is called the longitudinal direction.

[0031] Automatic welding process: The first transfer robot 4 transfers the integrated circuit board 25 from the first conveyor belt 5 to the feed end of the second conveyor belt 1. The second conveyor belt 1 operates intermittently, and in one movement, the integrated circuit board 25 at the feed end is transported to the bottom of the correction mechanism 2. The longitudinal pushing components 21 and the conveyor belt 24 on both sides of the integrated circuit board 25 adjust it longitudinally to make it centered as a whole. Then the adjustment component 23 lowers the fence 26 to the surface of the second conveyor belt 1, and uses the fence 26 to adjust it horizontally so that the edge of the integrated circuit board 25 is aligned with the second conveyor belt 1. The longitudinal edges are parallel, and the centering of the integrated circuit board 25 is completed at this time. The longitudinal pushing component 21 and the fence 26 are reset, and the second conveyor belt 1 continues to operate to transport the centrally positioned integrated circuit board 25 to the automatic insertion machine 3, and the electronic components on the surface of the integrated circuit board 25 are inserted in the automatic insertion machine 3. The integrated circuit board 25 that has completed insertion is transferred by the second transfer robot 6 to the seventh conveyor belt 7, and the seventh conveyor belt 7 transports the integrated circuit board 25 to the bottom of the seventh conveyor belt 7, and the seventh conveyor belt 7 performs automatic welding of the integrated circuit board 25 and the electronic components.

[0032] The working principle of the longitudinal pushing component for longitudinal adjustment: under the push of the second conveyor belt 1, the edge of the integrated circuit board 1 25 on one side away from the feed end is against the baffle 241, and the conveyor belt 24 is driven to operate through the baffle 241. The operation of the conveyor belt 24 drives the gear 2 242 to rotate, and the gears 242 on both sides are fixedly connected by the connecting rod 243 to ensure that the gears 242 on both sides rotate synchronously. In addition, the rotation of the gear 242 drives the gear 1 216 to rotate, and the rotation of the gear 1 216 drives the rack 214 to slide toward the integrated circuit board 1 25, and the gear 1 216 meshing with the gear 242 is fixedly connected to another gear 1 216 through the connecting rod 1 217. The synchronous rotation of the two gears 1 216 drives the rack 214 to slide out synchronously, and the rack 214 located on the other side of the second conveyor belt 1 slides out synchronously, so that the integrated circuit board 1 25 is located in the longitudinal center position of the second conveyor belt 1. At this time, the integrated circuit board 1 25 is located directly below the fence 26.

[0033] The working principle of the correction assembly for lateral correction is as follows: the hydraulic cylinder 231 controls the hanging frame 233 to descend through the telescopic rod 232, and then drives the fence 26 to descend through the slide 234, so that the bottom surface of the fence 26 contacts the upper surface of the second conveyor belt 1. At this time, the fence 26 is located on both sides of the integrated circuit board 25, and the probe 263 is not in contact with the integrated circuit board 25, so 267 is not connected to the terminal 268. The motor 235 is started and controls the sliders 237 at both ends to move toward each other through the screw rod 236, so that the fences 26 on both sides are close to the integrated circuit board 25. At this time: If the edge of the integrated circuit board 25 is parallel to the fence 26, the probes 263 on both sides will be retracted into the fence 26 under the pressure of the fence 26 and the two sides of the integrated circuit board 25 until the ends 267 of the probes 263 are connected with the terminals 268 inside the inner groove 264, and the motor 235 stops running. If the edge of integrated circuit board 1 25 is not parallel to fence 26, the probe 263 at the left or right end of fence 26 will be compressed and retracted, connecting the corresponding probe 267 with terminal 268. However, the probe 263 at the other end will not retract or retract insufficiently, preventing the corresponding probe 267 from connecting with terminal 268. Hydraulic cylinder 261 on the connected side will control telescopic rod 262 to push out, while hydraulic cylinder 261 on the unconnected side will remain inactive. It should be noted that the pressure on probes 263 at the bottom of fence 26 on both sides, i.e., the connection between probes 267 and terminal 268, is symmetrical around the center. Therefore, the activated hydraulic cylinders 261 are diagonally distributed. Under the push of telescopic rod 262 at the diagonal position, the angle of inclination of integrated circuit board 1 25 relative to fence 26 gradually decreases until it becomes parallel to fence 26.

[0034] 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 in the scope of protection of the present invention.
