Description

[0002] Circuit boards are important electronic components, supporting bodies for electronic components, and carriers for electrical connections between electronic components. Almost every electronic device, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, as long as there are electronic components similar to integrated circuits, must use circuit boards to make electrical interconnections between the various components. Currently, electronic components are integrated on circuit boards by soldering. With the rapid development of the economy, in order to improve production efficiency, fully automatic soldering machines that can automatically perform soldering operations have emerged. To a certain extent, they have replaced manual labor and greatly improved welding work efficiency.

[0003] To ensure soldering accuracy, current automatic soldering machines typically use flux. Specifically, flux is sprayed onto the hot melt portion of the solder through a nozzle to remove the oxide layer on the surface of the solder rod and reduce the surface tension of the solder. However, the flux may be unevenly distributed after being sprayed, with some areas having too much flux and others having too little or even no flux.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1 of the present invention further describes a soldering device for integrated circuit board production, including a base 100, wherein the upper end surface of the base 100 is fixedly connected to a support frame 101, a movable base 102 is installed in the support frame 101, a mounting frame 103 is fixedly connected to the bottom end of the movable base 102, a welding head 104 is detachably connected to the mounting frame 103, a feeding pipe 105 is installed in the mounting frame 103, a tapered cavity 106 is formed in the feeding pipe 105, a tin bar 107 is wound around the movable base 102 by a movable roller, the tin bar 107 correspondingly passes through the feeding pipe 105, an auxiliary mechanism 200 for evenly applying the tin bar 107 is provided in the feeding pipe 105, a conveying mechanism 300 for transmitting the tin bar 107 is further provided in the feeding pipe 105, and a cleaning mechanism 400 for cleaning the outer surface of the tin bar 107 is provided in the feeding pipe 105;

[0034] Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Soldering is a welding method that uses low-melting-point metal solder to penetrate and fill the gaps between metal parts after heating and melting. During the processing of circuit boards, a soldering device is required to solder the circuit components on the circuit board, so that the circuit board and the circuit components form a complete circuit. To ensure welding accuracy, current soldering machines usually use flux. Specifically, the flux is sprayed on the hot melt part of the solder through a nozzle to remove the oxide layer on the surface of the tin bar 107 and reduce the surface tension of the solder. However, the flux will be unevenly distributed when sprayed.

[0035] Therefore, the present invention provides an auxiliary mechanism 200 in the feeding tube 105, so that the flux can be evenly applied to the outer wall of the tin bar 107. At the same time, through gear transmission, the device can evenly apply the flux and transport the tin bar 107 through the conveying mechanism 300. In addition, the device is provided with a cleaning mechanism 400 in the feeding tube 105. The cleaning mechanism 400 is conducive to reducing the phenomenon of impurities adhering to the surface of the tin wire, thereby improving the welding quality. In this way, the device combines the auxiliary mechanism 200, the conveying mechanism 300 and the cleaning mechanism 400 through a linkage structure, thereby transporting, applying and cleaning the tin bar 107, further improving the welding quality.

[0036] The auxiliary mechanism 200 includes a support member 201 disposed in the feeding tube 105, a smear member 202 is disposed at the bottom end of the support member 201, a ring member 203 is disposed in the feeding tube 105, and a movable member 204 is disposed in the support member 201 to cooperate with the smear member 202. The ring member 203 and the movable member 204 cooperate to drive the smear member 202. Figures 1 to 10As can be seen, the present invention provides a corresponding supporting effect by disposing a support member 201 in the feeding tube 105. The bottom end of the support member 201 is provided with a smearing member 202 and a movable member 204. In this way, the device controls the smearing member 202 through the cooperation of the annular member 203 and the movable member 204, and the flux is evenly applied to the outer wall of the tin bar 107 by the smearing member 202.

[0037] The conveying mechanism 300 includes a gear member 301 disposed in the annular member 203, and a feeding member 302 is disposed on the side wall of the conical cavity 106. The gear member 301 and the feeding member 302 cooperate to convey the tin bar 107. Figures 3 to 9 It can be seen that the ring member 203 is provided with a gear member 301. When the ring member 203 operates, the gear member 301 operates synchronously. A feeding member 302 is provided in the conical cavity 106. In this way, the gear member 301 and the feeding member 302 cooperate to transport the tin bar 107 in the movable seat 102, achieving a dual-purpose effect.

[0038] The cleaning mechanism 400 includes a rotating member 401 disposed on the feeding member 302, a limiting member 402 is provided on the outer side of the rotating member 401, and a cleaning member 403 for cleaning the outer surface of the tin bar 107 is provided inside the limiting member 402. The rotating member 401 and the limiting member 402 cooperate to control the cleaning member 403;

[0039] Since the soldering machine consumes tin wire continuously when soldering the circuit board, the tin wire needs to be continuously moved to the welding position. However, there are usually some metal debris and dust in the factory. The metal debris and dust are easy to adhere to the surface of the tin wire. When soldering the circuit board, it is easy to have poor soldering quality problems. Therefore, cleaning the tin wire before welding wastes time and has low welding efficiency. The present invention provides a cleaning mechanism 400 on the outside of the feeding member 302, so that the conveying mechanism 300 cleans the tin wire during the process of conveying the tin wire, which is beneficial to reduce the phenomenon of impurities adhering to the surface of the tin wire, thereby helping to improve the welding quality.

[0040] Working principle: In summary, the present invention provides an auxiliary mechanism 200 in the feeding tube 105, so that the flux can be evenly applied on the outer wall of the tin bar 107, and the tin bar 107 is transported by the conveying mechanism 300 while being evenly applied. At the same time, the cleaning mechanism 400 is beneficial to reduce the phenomenon of impurities adhering to the surface of the tin wire, thereby improving the welding quality. In this way, the device transmits, applies and cleans the tin bar 107 through the linkage structure, further improving the welding quality, which not only reduces the additional power demand, but also reduces the cost and complexity of the equipment.

[0041] Example 2

[0042] On the basis of the first embodiment, the following technical features are added: the support member 201 includes connecting blocks 201a fixedly connected to both sides of the inner wall of the tapered cavity 106, a supporting plate 201b is fixedly connected between the connecting blocks 201a on both sides, an opening 201c is provided in the middle position of the supporting plate 201b, an annular box 201d is detachably mounted on the upper end surface of the supporting plate 201b, a solder flux is arranged in the annular box 201d, a supporting block 201e is detachably mounted on the bottom end of the supporting plate 201b, the opening 201c extends into and passes through the supporting block 201e, a movable hole 201f is circumferentially provided at the portion of the opening 201c located at the supporting block 201e, a discharge trough 201g is circumferentially provided in the supporting plate 201b and the supporting block 201e, the discharge trough 201g is correspondingly connected to the annular box 201d, and an extrusion rod 201h is correspondingly slidably connected in the movable hole 201f;

[0043] Depend on Figures 2 to 8 As can be seen, the conical cavity 106 is symmetrically fixed with connection blocks 201a, and a circular support plate 201b is fixedly connected between the connection blocks 201a on both sides. A circular opening 201c is provided in the middle of the support plate 201b, and the tin bar 107 passes through the opening 201c. A ring box 201d is detachably mounted on the upper end surface of the support plate 201b, surrounding the opening 201c. The ring box 201d contains flux, so that the flux can be replaced.

[0044] The bottom of the support plate 201b is detachably mounted with a circular support block 201e, and the opening 201c extends into and penetrates the support block 201e. A corresponding tin bar 107 is penetrated in the opening 201c. The inner wall of the support block 201e is provided with three groups of movable holes 201f in a circular shape, and the movable holes 201f are provided with six groups in the vertical direction. The corresponding sliding connection of the movable holes 201f is provided with an extrusion rod 201h. The extrusion rod 201h is moved in the movable hole 201f. , so that the flux is ejected from the movable hole 201f. The main working process is as follows: first, the flux is discharged from the annular box 201d, and then flows into the discharge trough 201g. When the extrusion rod 201h cuts off the discharge trough 201g, the flux fails to flow into the movable hole 201f. When the extrusion rod 201h slides in the movable hole 201f, the flux falls into the movable hole 201f, and then the flux is pushed out by the extrusion rod 201h, thereby abutting against the outer wall of the smear member 202;

[0045] The smear member 202 includes a porous plate 202a provided in the opening, one end of the extrusion rod 201h is correspondingly pressed against the outer surface of the porous plate 202a, and a wiping block 202b is installed on the inner wall of the porous plate 202a. The wiping block 202b is made of sponge material and is used to absorb the soldering flux from the movable hole 201f. Figure 5As can be seen, a circular porous plate 202a is provided in the opening. As can be seen from the above, the flux is discharged into the outer wall of the porous plate 202a through the movable holes 201f. In addition, the distribution arrangement of the movable holes 201f is further limited in this device, so that the wiping block 202b can evenly absorb the flux. When the porous plate 202a drives the wiping block 202b to rotate, the flux can be evenly applied to the outer wall of the tin bar 107.

[0046] The annular member 203 includes an annular groove 203a provided in the conical cavity 106, and also includes an annular plate 203b. An annular edge 203c is integrally formed on the inner and outer walls of the annular plate 203b. The annular edge 203c is correspondingly slidably connected in the annular groove 203a. The upper end surface of the annular plate 203b is provided with a groove 1 203d, the bottom end of the annular plate 203b is provided with a groove 203e, and the middle position of the annular plate 203b is provided with a second opening 203f. A circular plate 203g is fixedly connected to the groove 203e. The second opening 203f corresponds to The outer wall of the circular plate 203g is integrally formed with a diameter reducing portion 203h in a circular shape. The porous plate 202a is fixedly connected to the lower end surface of the bottom end of the circular plate 203g. A fixed plate 203i is fixedly connected to one side of the inner wall of the tapered cavity 106. A rotary electric cylinder 203j is detachably mounted on the upper end surface of the fixed plate 203i. The output shaft end of the rotary electric cylinder 203j is keyed to a gear 1 203k. A gear ring 203l is fixedly connected to the inner wall of the slot 2 203e. The gear ring 203l is correspondingly engaged with the gear 1 203k.

[0047] Depend on Figures 3 to 10 It can be seen that in order to ensure the stability of the rotation of the annular plate 203b, an annular edge 203c is integrally formed on the outer wall of the annular plate 203b, and an annular groove 203a is provided on the inner wall of the conical cavity 106. The annular plate 203b is slidably connected to the annular groove 203a via the corresponding annular edge 203c. At the same time, the present invention further defines the structure of the annular plate 203b. A slot 1 203d and a slot 2 203e are respectively provided on both sides of the annular plate 203b. The conveying mechanism 300 and the cleaning mechanism are arranged in the slot 1 203d, and the auxiliary mechanism 200 is arranged in the slot 2 203e. The bottom end of the annular plate 203b is fixedly connected to a circular plate 203g. Three groups of diameter-reducing portions 203h are integrally formed on the outer wall of the circular plate 203g. The porous plate 202a is fixedly connected to the circular plate 203g correspondingly. The diameter-reducing portion 203h consists of an expanded diameter surface 203m and a curved surface 203n.

[0048] Depend on Figure 8 and Figure 9It can be seen that the diameter-reducing portion 203h is an arc-shaped structure with a continuously changing radius, which is mainly composed of an expanded diameter surface 203m and a curved surface 203n. The expanded diameter surface 203m is a portion with an increased radius, and the curved surface 203n is a portion with a gradually decreased radius. In this way, the annular plate 203b rotates, so that the annular plate 203b drives the circular plate 203g to rotate synchronously. At this time, the diameter-reducing portion 203h generates an extrusion force on the slide bar 204c. Its driving source is a rotary electric cylinder 203j fixed to the inner wall of the tapered cavity 106. The rotary electric cylinder 203j drives the gear 1 203k to rotate. The gear 1 203k is correspondingly engaged with the ring gear 203l. The ring gear 203l is fixedly connected to the annular plate 203b. In this way, when the rotary electric cylinder 203j drives the gear 1 203k to rotate, it drives the annular plate 203b in the ring gear 203l to rotate.

[0049] The movable member 204 includes a sliding hole 204a circumferentially opened on the upper end surface of the support plate 201b, a limiting groove 204b is provided inside the sliding hole 204a, a sliding rod 204c is slidably connected in the sliding hole 204a and the limiting groove 204b, and a tension spring 204d is fixedly connected to the side wall of the sliding rod 204c. The tension spring 204d is a carbon spring with high strength and is convenient for daily use. One end of the tension spring 204d is fixedly connected to the inner wall of the sliding hole 204a, and one end of the sliding rod 204c is provided on the side of the reducing portion 203h. The extrusion rod 201h is correspondingly fixedly connected to the outer wall of the sliding rod 204c;

[0050] Depend on Figures 5 to 10 It can be seen that the upper end surface of the support plate 201b is circumferentially provided with three groups of long strip-shaped sliding holes 204a, and T-shaped limiting grooves 204b are provided on both sides of the inner wall of the sliding hole 204a. The sliding hole 204a and the limiting groove 204b are connected to the sliding rod 204c through the tension spring 204d, and one end of the sliding rod 204c is arranged on the side of the diameter-reducing part 203h. As can be seen from the above, the rotation of the annular plate 203b drives the diameter-reducing part 203h to rotate at the same time, so that the corresponding extrusion sliding rod 204c of the diameter-reducing part 203h drives the sliding rod 204c to move in the sliding hole 204a, thereby driving the extrusion rod 201h on the sliding rod 204c to slide in the movable hole 201f;

[0051] Working principle: As can be seen from Example 1, when the present device is used, the rotary electric cylinder 203j is activated by the external controller, and the rotary electric cylinder 203j drives the gear 1 203k at the output shaft end to rotate, and the ring gear 203l is correspondingly engaged with the gear 1 203k, thereby driving the annular plate 203b outside the ring gear 203l to rotate, and when the annular plate 203b rotates, it drives the circular plate 203g to rotate, and when the circular plate 203g rotates, it drives the diameter reducing part 203h to rotate, at this time, the diameter expanding surface 203m and the curved surface 203n on the diameter reducing part 203h contact the slide bar 204c in turn, and when the diameter expanding surface 203m contacts the slide bar 204c, When the sliding rod 204c is in contact with the curved surface 203n, the sliding rod 204c is driven to move inward in the sliding hole 204a by the restoring force of the tension spring 204d. In this way, the sliding rod 204c drives the extrusion rod 201h on the inner wall to slide in the movable hole 201f. At this time, the flux is discharged into the outer wall of the porous plate 202a through the movable hole 201f, so that the wiping block 202b can evenly absorb the flux, so that when the porous plate 202a drives the wiping block 202b to rotate, the flux can be evenly applied to the outer wall of the tin bar 107, thereby improving the quality of welding.

[0052] In the third embodiment, a soldering device for producing integrated circuit boards according to the present invention is further described. The gear member 301 includes a second gear 301a fixedly connected to the upper end surface of the first slot 203d. A circular opening 301b is provided in the middle of the second gear 301a. The second gear 301a is meshedly connected to the third gear 301c. The third gear 301c is keyed to a rotating rod 301d. A linkage plate 301e is fixedly connected to the side wall of the tapered cavity 106. The rotating rod 301d is rotatably connected to the linkage plate 301e via a bearing. The feeding member 302 includes a feeding wheel 302a fixedly connected to the upper end of the rotating rod 301d. A feeding trough 302b is provided in the feeding wheel 302a. The tin bar 107 is provided in the feeding trough 302b.

[0053] Depend on Figures 4 to 7 It can be seen that the upper end surface of the annular plate 203b is fixedly connected to the gear 2 301a. It can be seen from the above that when the annular plate 203b rotates, the gear 2 301a is driven to rotate synchronously. The side wall of the conical cavity 106 is fixedly connected to the straight bar-shaped linkage plate 301e. The linkage plate 301e is rotatably connected to the rotating rod 301d through the bearing. The bottom end of the rotating rod 301d is fixedly connected to the gear 3 301c. The gear 2 301a is meshed with the gear 3 301c. In this way, the rotating rod 301d in the gear 3 301c is driven to rotate by the gear 2 301a, and the upper end of the rotating rod 301d is fixedly connected to the feed wheel 302a. At this time, the feed trough 302b in the feed wheel 302a transmits the tin bar 107.

[0054] Working principle: As can be seen from Example 1, when the device is in use, when the annular plate 203b rotates, it drives the gear 2 301a to rotate synchronously. The gear 2 301a is meshed with the gear 3 301c. The gear 3 301c drives the rotating rod 301d to rotate synchronously. The rotating rod 301d drives the feed wheel 302a to rotate. At this time, the feed wheel 302a rotates to transmit the tin bar 107, thereby reducing the additional power demand and reducing the cost and complexity of the equipment.

[0055] The fourth embodiment further describes a soldering device for integrated circuit board production according to the present invention. The rotating member 401 includes a movable ring 401a fixedly connected to the outer wall of the rotating rod 301d. The outer wall of the movable ring 401a is provided with a wave groove 401b. The wave groove 401b includes a high portion 401c and a low portion 401d.

[0056] Since metal debris and dust are easily attached to the surface of the tin wire, it is easy to cause poor soldering quality problems when soldering the circuit board. Figure 7 It can be seen that a circular movable ring 401a is fixedly connected to the outer wall of the rotating rod 301d, and a wave groove 401b is provided on the outer wall of the movable ring 401a. Therefore, when the rotating rod 301d rotates, the movable ring 401a on the rotating rod 301d is driven to rotate synchronously.

[0057] The limiting member 402 includes a limiting rod 402a that is slidably connected to the wave groove 401b, one end of the limiting rod 402a is fixedly connected to a cleaning rod 402b, the upper end surface of the linkage plate 301e is provided with a cleaning hole 402c, the cleaning rod 402b is correspondingly slidably connected to the cleaning hole 402c, one side of the cleaning rod 402b is fixedly connected to the limiting plate 402d, the bottom end of the linkage plate 301e is fixedly connected to a conical sleeve 402e, and the conical sleeve 402e is provided with a collecting groove 4 02f, cleaning member 403 includes a cleaning wheel 403a fixedly connected to one side of the limiting plate 402d, with a hollow hole 403b provided at the center of the cleaning wheel 403a, a conical groove 403c provided in the cleaning wheel 403a, a spherical block 403d is circumferentially installed in the conical groove 403c, and a cleaning strip 403e is fixedly connected to the outer wall of the spherical block 403d. The cleaning strip 403e is made of soft rubber, and the tin strip 107 passes through the hollow hole 403b accordingly;

[0058] Depend on Figures 7 to 10It can be seen that a cleaning rod 402b is slidably connected to the linkage plate 301e in the vertical direction, and the side wall of the bottom end of the cleaning rod 402b is fixedly connected to the limiting rod 402a, and the limiting rod 402a is correspondingly slidably connected to the wave groove 401b. Therefore, when the limiting rod 402a is slidably connected to the high part 401c, the cleaning rod 402b is at the highest point, and when the limiting rod 402a is slidably connected to the low part 401d, the cleaning rod 402b is at the lowest point. It can be seen that the cleaning rod 402b drives the cleaning wheel 403a on the limiting plate 402d to move in the vertical direction;

[0059] To ensure effective cleaning of the tin bar 107, the cleaning wheel 403a is provided with an annular conical groove 403c. A spherical block 403d is removably mounted in the conical groove 403c. A flexible cleaning strip 403e is fixed to the outer wall of the spherical block 403d. When the cleaning wheel 403a moves vertically, the cleaning strip 403e on the spherical block 403d cleans the outer wall of the tin bar 107.

[0060] Working principle: It can be seen from Example 3 that when gear three 301c drives the rotating rod 301d to rotate, the rotating rod 301d drives the movable ring 401a to rotate. At this time, the wave groove 401b on the movable ring 401a rotates synchronously. Since the limiting rod 402a is correspondingly slidably connected in the wave groove 401b, when the limiting rod 402a is slidably connected to the high-position part 401c, its cleaning rod 402b is at the highest point. When the limiting rod 402a is slidably connected to the low-position part 401d, its cleaning rod 402b is at the lowest point. Therefore, the cleaning rod 402b drives the cleaning wheel 403a on the limiting plate 402d to move in the vertical direction. At this time, the cleaning strip 403e on the spherical block 403d cleans the outer wall of the tin bar 107, thereby reducing the phenomenon of impurities adhering to the surface of the tin wire, which is beneficial to improving the welding quality.
