The directional terms used are for the purpose of explaining and understanding this invention, and are not intended to limit this invention.

[0030] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, a connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] In existing technologies, equipment for soldering circuit boards typically consists of a linear motion module, such as a linear motor, mounted on a base. A platform for placing the circuit board is mounted on the mover of the linear motor. The soldering head is connected to the moving module, and the circuit board is fixed on the platform. A fixture is then placed on the platform, and the moving module is controlled by a computer to move, thereby controlling the soldering head to solder the circuit board. However, this structure is not convenient or efficient for picking up, placing, and fixing circuit boards, and the workload of operators is still relatively large, which also affects production efficiency.

[0033] The following is a preferred embodiment of a soldering machine provided by the present invention that can solve the above-mentioned technical problems.

[0034] Please refer to Figure 1 ,in Figure 1 This is a schematic diagram of a preferred embodiment of the soldering machine of the present invention.

[0035] In the diagram, units with similar structures are represented by the same labels.

[0036] This invention provides a soldering machine, comprising a base 11, a moving module 12, a solder breaking and feeding mechanism 14, a solder head 13, and a support mechanism 15, the support mechanism 15 being used to place products. Both the solder head 13 and the solder breaking and feeding mechanism 14 can adopt existing conventional structures. The solder breaking and feeding mechanism 14 is used to feed solder wire to the solder head 13. During the solder feeding process, the solder breaking and feeding mechanism 14 can use a blade to punch or cut holes in the solder wire. The main function of punching and cutting is to break the solder wire, allowing the flux (such as rosin) inside the solder wire to be relatively evenly distributed or to open up enclosed spaces, facilitating soldering and improving the soldering effect.

[0037] The movable module 12 is connected to the base 11, and in this embodiment, a crossbeam is provided on the base, with the movable module 12 mounted on the crossbeam. The solder head 13 is connected to the movable module 12 and is driven to move, thereby soldering different positions on the circuit board. The solder breaking and feeding mechanism 14 is connected to the base 11 and located on one side of the solder head 13, while the support mechanism 15 is provided on the base 11 and located below the solder head 13.

[0038] Please refer to Figure 2In this embodiment, the support mechanism 15 includes a support frame, a product positioning frame, a fixture positioning frame, and a drive component 24. The support frame is mounted on the base 11, with one side serving as a mounting surface. The product positioning frame is connected to the mounting surface, and the fixture positioning frame is slidably connected to the mounting surface and positioned above the product positioning frame. The fixture positioning frame is used to mount fixtures, which cover the product and expose only the parts of the product that require soldering, thus protecting the product. The drive component 24 is mounted on the support frame, and its drive end is connected to the fixture positioning frame to drive the fixture positioning frame to slide, either docking with or avoiding the product positioning frame. When docking, soldering can be performed; when avoiding the product positioning frame, it facilitates product placement and removal, making the operation convenient and efficient.

[0039] In this embodiment, two support mechanisms 15, a double-set solder breaking and feeding mechanism 14, and a double-set solder head 13 are provided. When loading and unloading operations are performed on one support mechanism 15, the products on the other support mechanism 15 can be soldered normally, resulting in high work efficiency.

[0040] In this embodiment, a housing 111 is provided on the top of the base 11. The moving module 12, the solder breaking and feeding mechanism 14, the solder head 13, and the support mechanism 15 are located inside the housing 111. An operation port 112 is provided on one side of the housing 111, and the mounting surface is inclined towards the operation port 112, making it easier and more convenient for the operator to pick up and put down the components. A linear drive mechanism is provided on the base 11. Figure 1 In the orientation, the linear drive mechanism is located below the support mechanism 15 (it is obscured and not shown). The support frame is connected to the linear drive mechanism to perform linear sliding. In conjunction with the movement of the solder head 13, it can perform soldering operations on various positions of the product.

[0041] In this embodiment, a waste box 25 is provided on the side of the support frame away from the operation port 112, which can be used to collect waste solder dross. In this embodiment, the solder breaking and feeding mechanism 14 is fixedly connected to the top wall of the outer casing 111 by an extension plate 141.

[0042] Please refer to Figure 2 In this embodiment, the support frame includes a base plate 211 and side plates 212 connected to both ends of the base plate 211. The side plates 212 are triangular, and the mounting surface is located on the side with the inclined edge, so that the mounting surface is inclined towards the operating port 112. The driving component 24 is located on one side of the side plate 212. The driving component 24 can be a cylinder. One end of the driving component 24 is movably connected to the base plate 211, and the driving end of the driving component 24 is movably connected to the fixture positioning frame. The overall structure is compact, and the position of the driving component 24 is concealed, so it will not affect the soldering operation and the loading and unloading operation.

[0043] In this embodiment, the support frame is provided with connecting grooves 215 at both ends. The product positioning frame includes a frame body and a connector 223. The connector 223 is connected to both ends of the frame body. The connector 223 is slidably connected to the connecting groove 215. The connector 223 is fixed to the connecting groove 215 by bolts. The frame body can be disassembled by loosening the bolts.

[0044] Optionally, the frame can be designed as a single unit, allowing the entire frame to be replaced and used to secure products of different sizes and specifications.

[0045] Preferably, the frame may include two fixed positioning strips 222 and one movable positioning strip 221. Two connectors 223 are respectively connected to both ends of the movable positioning strip 221. The two fixed positioning strips 222 are respectively fixedly connected to two adjacent sides of the support frame. In this way, by loosening the bolts and adjusting the position of the movable positioning strip 221, the product positioning space between the fixed positioning strips 222 and the movable positioning strip 221 can be adjusted. It should be noted that the two fixed positioning strips 222 need to be of sufficient length to accommodate the sliding adjustment of the movable positioning strip 221.

[0046] Please refer to Figure 4 The frame may also include reinforcing positioning components, including a swing arm 225, an arc-shaped fixing rod 226, and a support block 227 slidably connected to the swing arm 225. The two ends of the arc-shaped fixing rod 226 are fixedly connected to two fixing positioning strips 222 respectively. One end of the swing arm 225 is rotatably connected to the intersection of the two fixing positioning strips 222, and the other end is slidably connected to the arc-shaped fixing rod 226. The support block 227 is slidably connected to the swing arm 225. The support block 227 is used to support the central area of ​​the circuit board. By rotating and adjusting the swing arm 225, and simultaneously sliding and adjusting the support block 227, the support block 227 can support circuit boards of different sizes and specifications. Furthermore, after adjusting its position, the support block 227 can also be used to avoid electronic components on the circuit board.

[0047] It should be noted that the rocker arm 225 and the arc-shaped fixed rod 226 are connected by a sliding connection with a certain interference force, and the support block 227 and the rocker arm 225 are connected by a sliding connection with a certain interference force.

[0048] Please refer to Figure 2 and Figure 3In addition, the frame is provided with a positioning groove for positioning and placing products. One side of the product positioning frame is elastically slidably connected to a first locking member 213 for fixing the product through a first elastic member 2134. The first locking member 213 is located on the side parallel to the sliding trajectory of the fixture positioning frame. The sliding trajectory of the first locking member 213 is parallel to the outer surface of the product and perpendicular to the sliding trajectory of the fixture positioning frame. The first elastic member 2134 is used to drive the first locking member 213 away from the product in the positioning groove. The fixture positioning frame is provided with a first pressing member 233. When the fixture positioning frame is docked with the product positioning frame, the first pressing member 233 presses the first locking member 213 to lock the product in the positioning groove.

[0049] The first locking member 213 includes a first locking end 2132 and a first pressure end 2131. The first locking end 2132 is provided with a chamfered edge that facilitates fixed contact with the product surface. A slider 2133 is provided at the bottom of the first locking member 213. A slide groove is provided on the product positioning frame that is slidably connected to the slider 2133. A first elastic member 2134 is provided between the inner wall of the slider 2133 and the slide groove.

[0050] Furthermore, a second locking member 214 is provided on the other side of the product positioning frame. The second locking member 214 is elastically rotatably connected to the product positioning frame via a torsion spring. The second locking member 214 is located on the side perpendicular to the sliding trajectory of the fixture positioning frame. The two ends of the second locking member 214 are a second locking end and a second pressure end, respectively. The torsion spring is used to drive the second locking end away from the product in the positioning groove. A second pressing member 234 is provided on the fixture positioning frame. When the fixture positioning frame is docked with the product positioning frame, the second pressing member 234 presses the second pressure end, so that the second locking end locks the product in the positioning groove. In this embodiment, the second locking member 214 has an L-shaped structure.

[0051] Please refer to Figure 2 and Figure 5 Two connecting slots 215 are respectively located at the top and bottom of the mounting surface. A connector 223 can be slidably connected to the connecting slots 215 via a sliding sleeve 228. A sliding post 2231, which can slide but cannot be pulled out, can be provided on the connector 223. The sliding sleeve 228 is fixed to the connecting slot 215 by a bolt 2281. Tightening the bolt 2281 causes the sliding sleeve and connecting slot 215 to expand and become fixed. The bolt 2281 can be a bolt that is easy to tighten manually. The connector 223 is elastically slidably connected to the sliding sleeve 228 via a second elastic element 229. The sliding trajectory is consistent with the trajectory of the sliding sleeve 228. The second elastic element 229 is used to drive the movable positioning strip 221 away from the product in the positioning slot. When the fixture positioning frame slides and avoids the product positioning frame, under the elastic force of the second elastic element 229, the positioning slot formed between the movable positioning strip 221 and the fixed positioning strip 222 can automatically expand, which is very convenient for picking up and placing products, making loading and unloading very convenient.

[0052] It should be noted that the movable positioning bar 221 can slide with a small stroke, and the expansion or contraction of the positioning groove between the movable positioning bar 221 and the fixed positioning bar 222 does not need to be very large.

[0053] The connector 223 is provided with a pressure-bearing component 224, and the fixture positioning frame is provided with a third pressing component 235 for pressing the pressure-bearing component 224. When the fixture positioning frame is docked with the product positioning frame, the third pressing component 235 presses the pressure-bearing component 224, so that the movable positioning strip 221 comes into contact with the product, thereby better positioning the product and facilitating stable and accurate soldering.

[0054] Please refer to Figure 6 When the product is as follows Figure 2 When the circuit board 41a is square, it can be directly positioned using fixed positioning strip 222 and movable positioning strip 221. Figure 6 When dealing with irregularly shaped circuit boards 41b, positioning plates can be connected to the fixed positioning strip 222 and / or the movable positioning strip 221 to accommodate circuit boards of different shapes and specifications.

[0055] Specifically, both the fixed positioning strip 222 and the movable positioning strip 221 are provided with a first notch 2211 for forming a positioning groove. A positioning plate 31 is detachably connected to the first notch 2211 of the fixed positioning strip 222 and / or the movable positioning strip 221. The positioning plate 31 can be connected to the fixed positioning strip 222 or the movable positioning strip 221 by screws. A second notch 311 for forming a positioning groove is provided on the positioning plate 31.

[0056] Positioning plate 31 is not limited to Figure 6 The shape can also be curved or other shapes, and can be configured according to the specific situation of the circuit board.

[0057] In this embodiment, the fixture positioning frame includes a frame 231 and a connecting rod 232 slidably connected to the frame 231. The fixture is detachably connected to the connecting rod 232.

[0058] The working principle of the soldering machine of the present invention is as follows: When material needs to be loaded, the driving component 24 drives the fixture positioning frame to slide upward, and the fixture positioning frame and the product positioning frame are out of place. At this time, under the elastic force of the second elastic component 229, the positioning groove formed between the movable positioning strip 221 and the fixed positioning strip 222 can automatically expand, so that the product can be placed very conveniently.

[0059] After the product is placed, the drive component 24 drives the fixture positioning frame to slide down, aligning it with the product positioning frame, and the fixture covers the product surface. Simultaneously, the first pressing component 233 presses against the first locking component 213 to lock the product within the positioning groove; the second pressing component 234 presses against the second pressure-receiving end, causing the second locking end to lock the product within the positioning groove; and the third pressing component 235 presses against the pressure-receiving component 224, causing the movable positioning strip 221 to slide and shrink, thus stably fixing the product.

[0060] Then, the linear drive mechanism drives the support mechanism 15 to move below the solder head 13, while the moving module 12 controls the movement of the solder head 13 to solder different positions on the product.

[0061] After soldering is completed, the linear drive mechanism drives the support mechanism 15 to move closer to the operating port 112, the drive component 24 drives the fixture positioning frame to slide upward, the first elastic component 2134 drives the first locking component 213 to move away from the product in the positioning groove, the torsion spring drives the second locking component 214 to rotate, the second locking end moves away from the product in the positioning groove, and the second elastic component 229 drives the movable positioning bar 221 to slide, so that the positioning groove expands, thus making it easy to remove the product, and the operation is convenient and efficient.

[0062] This completes the loading, unloading, and soldering process of the soldering machine in this preferred embodiment.

[0063] The soldering machine of this preferred embodiment has a product positioning frame set on the mounting surface of the support frame, and a fixture positioning frame set above the product positioning frame. The fixture positioning frame is driven by a drive component to realize the docking or avoidance of the fixture and the product. When docking, soldering operation can be performed. When avoiding, it is convenient to pick up and put down the product. The operation is convenient and efficient.

[0064] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention.
