Description

Technical Field

[0001] The invention relates to the technical field of soldering machines, and in particular to a line-fixing soldering mechanism on a soldering machine. Background Art

[0002] The USB soldering machine is a device used for welding USB welding wires to USB heads. In order to improve the welding effect, a wire fixing mechanism is usually provided in the soldering mechanism. The existing wire fixing mechanism includes a wire clamp and a wire fork. The wire clamp and the wire fork can fix the welding wire on the fixture to improve the accuracy and stability of welding. When in use, first put the USB data cable or other welding wire into the wire groove opened on the surface of the fixed block in the chain transmission mechanism, and insert the exposed part of the welding wire into the wire clamp. The function of the wire clamp is to initially fix the welding wire to ensure that it will not move significantly in subsequent operations. After the wire clamp initially fixes the welding wire, the wire fork will move down and press on the welding wire that has been fixed by the wire clamp. The purpose of this step is to fix the welding wire more stably to prevent it from moving due to external force during the welding process. On this basis, a pressure plate will be set up to further fix the welding wire and prevent problems such as the welding wire warping.

[0003] However, the prior art method of limiting the welding wire using structures such as wire clamps, wire forks and pressure plates has shortcomings. Since the pressure plate is too low, it is easy to rub against the welding wire and cause damage. If the pressure plate is too high, it cannot achieve the required fixing effect. In addition, the tail of the welding wire is relatively long. When the chain transmission mechanism drives the welding wire to move quickly, the welding wire that follows the movement is easy to swing due to inertia, causing the placed welding wire to swing off or even fall off. If it is not handled, it will cause biased welding, cold welding and the like. Therefore, the present invention provides a wire-fixing soldering mechanism on a soldering machine to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a wire-fixing soldering mechanism on a soldering machine to solve the shortcomings of the existing method of limiting the welding wire using structures such as wire clamps, wire forks and pressure plates. Since the pressure plate is too low, it is easy to rub against the welding wire and cause damage. If the pressure plate is too high, it cannot achieve the required fixing effect. In addition, the tail of the welding wire is long. When the chain transmission mechanism drives the welding wire to move quickly, the welding wire that follows the movement is easy to swing due to inertia, causing the placed welding wire to swing or even fall off.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A wire-setting soldering mechanism on a soldering machine comprises a main body and a frame, a chain mechanism is arranged on one side of the frame, the chain mechanism comprises a plurality of fixed blocks for placing welding wires, and a detachable lower wire clamp is installed at one end of the plurality of fixed blocks; a transverse movement mechanism and a vertical movement mechanism are also arranged on the frame, the transverse movement mechanism is used to drive a clamp end block which is coaxial with the lower wire clamp, the vertical movement mechanism is used to drive an upper wire fork located above the lower wire clamp, and a welding mechanism located on one side of the upper wire fork is also arranged on the vertical movement mechanism, the upper wire fork and the lower wire clamp are arranged alternately, a wire pressing plate is fixedly connected to one end of the vertical movement mechanism close to the fixed block, and when the vertical movement mechanism moves downward, the wire pressing plate is driven to press the welding wire in the fixed block; a wire-setting mechanism is also included, which is used to fix the exposed end of the welding wire in the fixed block, and the wire-setting mechanism is connected to the lower wire clamp.

[0007] As a further improvement of the above technical solution:

[0008] Optionally, the line-fixing mechanism includes a first groove and a mounting groove formed at the top of the lower line clamp, and a plurality of first line teeth fixedly connected to the mounting groove, a detachable clamping member is also installed in the mounting groove, the clamping member includes an assembly block with a plurality of line-fixing openings, a first extrusion sheet and a pair of second extrusion sheets are fixedly connected to the plurality of line-fixing openings, wherein the first extrusion sheet and the pair of second extrusion sheets are both elastic structures, and cooperate with each other to form a triangular arrangement; the pair of second extrusion sheets each include a protrusion and a recessed portion; by a machine or a person skilled in the art After cutting, stripping and separating the welding wire, the worker places the exposed end of the welding wire in the wire fixing port, and the welding wire first contacts the raised portion. Since the second extrusion sheet, the raised portion and the recessed portion are an integrated elastic structure, the raised portion undergoes elastic deformation when squeezed, so that the welding wire can enter the triangular arrangement area. The elastic structure of the triangular arrangement can clamp the side surface of the welding wire at three points, and the raised portion limits the welding wire to prevent the welding wire from being squeezed out, so that the welding wire is effectively fixed, thereby solving the problem that when the chain mechanism drives the fixing block to quickly switch positions, the welding wire is The tail of the welding wire is long and easy to swing, causing the placed welding wire to swing or even fall off; in addition, when the welding wire enters the triangular area formed by the first extrusion sheet and the pair of second extrusion sheets, the spring sheet in the area can be squeezed to expand the spring sheet in the area. Therefore, the second extrusion sheet, the protrusion and the recessed portion of the elastic structure cooperate with each other to adapt to welding wires of different thicknesses, and can always keep in contact with the surface of the welding wire, which is suitable for welding wires of different thicknesses; in addition, since the chain mechanism drives the welding wire in the fixed block to move, when the welding mechanism presses down the welding wire and the USB head for welding, the welding wire is susceptible to partial movement of the welding head, causing the welding wire to be subjected to tension. Due to the setting of the first extrusion sheet and the pair of second extrusion sheets of the elastic structure, the welding wire can be kept in a centered position. On the one hand, when the welding wire is subjected to tension, the welding wire squeezes and contacts the above-mentioned elastic structure, which can play a buffering role to prevent the welding wire from being pulled and scratched and affecting the good product. On the other hand, when the tail of the welding wire is long and swings, the above-mentioned elastic structure can also be elastically reset on the basis of fixing the welding wire.

[0009] Optionally, a accommodating area is formed between the first side plate and the second side plate, an inlet and outlet are formed between the baffle and the arc-shaped plate, the upper wire fork includes a fixing plate, a plurality of slots are formed at one end of the fixing plate close to the lower wire clamp, and expansion plates of corresponding sizes are fixedly connected in the plurality of slots, the expansion plate includes a first side plate and a second side plate which are arranged opposite to each other, and the first side plate and the second side plate are connected at the top ends, a baffle is hingedly connected to the bottom end of the first side plate, wherein the baffle is an arc structure, and the concave portion of the arc structure faces the accommodating area, and the baffle is unidirectionally flipped, and the flipping direction faces the accommodating area, so that when the vertical movement mechanism drives the upper wire fork to move downward, the welding wire will first contact the baffle to cause the baffle to flip inward, and at the same time, the welding wire enters the accommodating area through the inlet and outlet, and the welding wire contacts the top wall in the accommodating area, so that the accommodating area can accommodate the welding wire. The part near the exposed end is limited on the top and both sides to reduce the problem that the part of the welding wire near the exposed end is easy to bend when it is squeezed; since the baffle is flipped in one direction, the baffle cannot be opened outward, and when the upper wire fork is reset upward, the baffle and the accommodating area cooperate to limit the welding wire. During the resetting process, the welding wire fixed between the first extrusion plate and the second extrusion plate can be disengaged due to the limiting effect. Subsequently, when the chain mechanism drives the fixed block to move, the subsequent stripping mechanism is conducive to taking out the welding wire in the fixed block. Since the upper wire fork and the lower wire clamp are on the same axis and there is a partial distance between the upper wire fork and the lower wire clamp, when the front end of the welding wire is located between the upper wire fork and the lower wire clamp, the upper wire fork and the lower wire clamp can make the welding wire located between the upper wire fork and the lower wire clamp maintain the same axis, thereby achieving the effect of keeping the front end of the welding wire straight.

[0010] Optionally, the installation groove passes through a plurality of the first wire teeth, the clamping member is located in the installation groove and slides within a limited position, and a screw rod threadedly connected to the assembly block is rotatably connected in the installation groove, and one end of the screw rod extends outward and is fixedly connected to a knob.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] In the above scheme, by setting up a wire-fixing mechanism, the side surfaces of the welding wire can be elastically clamped to improve the clamping effect, and the problem that when the chain mechanism drives the fixing block to quickly switch positions, the welding wire tail is long and prone to swinging, causing the placed welding wire to swing or even fall off is solved; in addition, the above structure can also adapt to welding wires of different thicknesses, and can always keep in contact with the surface of the welding wire, and is suitable for welding wires of different thicknesses.

[0013] By setting the above structure, when the welding wire is subjected to tension, the welding wire squeezes and contacts the above elastic structure, which can play a buffering role and prevent the welding wire from being pulled and scratched, thereby affecting the quality of the product. In addition, when the tail of the welding wire is long and swings, the above elastic structure can perform elastic reset on the basis of fixing the welding wire, thereby reducing the deviation of the welding wire and playing a corrective role.

[0014] By providing an expansion plate on the upper wire fork, the upper part and both sides of the part of the welding wire close to the exposed end can be limited, thereby reducing the problem that the part of the welding wire close to the exposed end is easily bent when squeezed; and during the resetting process, the welding wire fixed between the first extrusion plate and the second extrusion plate can be dislodged due to the limiting effect, which is beneficial to the subsequent welding wire removal.

[0015] Through the cooperation between the upper wire fork and the lower wire clamp in the above structure, the welding wire between the upper wire fork and the lower wire clamp can also maintain the same axis, thereby achieving the effect of keeping the front end of the welding wire straight.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the present invention provides a wire-setting soldering mechanism on a soldering machine, comprising a main body 1 and a frame 2, a chain mechanism 3 is arranged on one side of the frame 2, the chain mechanism 3 comprises a plurality of fixed blocks 9 for placing soldering wires, and a detachable lower wire clamp 10 is installed at one end of the plurality of fixed blocks 9; a transverse movement mechanism 4 and a vertical movement mechanism 5 are also arranged on the frame 2, the transverse movement mechanism 4 is used to drive a clamp end block 8 which is coaxial with the lower wire clamp 10, the vertical movement mechanism 5 is used to drive an upper wire fork 7 located above the lower wire clamp 10, and the vertical movement mechanism 5 is also provided with a detachable lower wire clamp 10 located at the upper wire fork 7. The welding mechanism 6 on one side, the upper wire fork 7 and the lower wire clamp 10 are arranged alternately, and the end of the vertical movement mechanism 5 close to the fixed block 9 is fixedly connected to the wire pressing plate 33, and a wire groove is opened on the upper surface of the fixed block 9, and the welding wire is placed in the wire groove. When the vertical movement mechanism 5 moves downward, it drives the wire pressing plate 33 to press the welding wire in the fixed block 9. The transverse movement mechanism 4 and the vertical movement mechanism 5 as well as the chain mechanism 3 and the welding mechanism 6 are all existing technical structures and will not be described in detail here; it also includes a wire fixing mechanism for fixing the exposed end of the welding wire in the fixed block 9, and the wire fixing mechanism is connected to the lower wire clamp 10.

[0039] like Figure 8 , Fig.10 and Fig.11 As shown, the routing mechanism includes a first groove 11 and a mounting groove 12 opened at the top of the lower wire clamp 10, and a plurality of first wire teeth 13 fixedly connected in the mounting groove 12. A detachable clamping member 14 is also installed in the mounting groove 12. The clamping member 14 includes an assembly block 15 with a plurality of routing openings 16. A first extrusion sheet 17 and a pair of second extrusion sheets 18 are fixedly connected in the plurality of routing openings 16. The first extrusion sheet 17 and the pair of second extrusion sheets 18 are both elastic structures and cooperate with each other to form a triangular arrangement. The pair of second extrusion sheets 18 each include a protrusion 19 and a recessed portion 16. After the welding wire is cut, stripped and separated by a machine or manually using the prior art, the exposed end of the welding wire is placed in the wire fixing port 16, and the welding wire first contacts the protrusion 19. Since the second extrusion sheet 18, the protrusion 19 and the recess 20 are an integrated elastic structure, when the protrusion 19 is squeezed, it undergoes elastic deformation, so that the welding wire can enter the triangular arrangement area. The elastic structure of the triangular arrangement can clamp the side surface of the welding wire at three points, and the protrusion 19 limits the welding wire to prevent the welding wire from being squeezed out, so that the welding wire is effectively fixed, thereby solving the problem of chain mechanism 3. When the fixed block 9 is driven to switch positions quickly, the tail of the welding wire is long and easy to swing, which may cause the placed welding wire to swing or even fall off; in addition, when the welding wire enters the triangular area formed by the first extrusion sheet 17 and the pair of second extrusion sheets 18, the spring sheet in the area can be squeezed to expand the spring sheet in the area. Therefore, the second extrusion sheet 18, the protrusion 19 and the recessed portion 20 of the elastic structure can cooperate with each other to adapt to welding wires of different thicknesses, and can always keep in contact with the surface of the welding wire, which is suitable for welding wires of different thicknesses; in addition, since the chain mechanism 3 is in the driving fixed block 9, the welding wire can be easily moved. During the movement of the welding wire, when the welding mechanism 6 presses down the welding wire and the USB head for welding, the welding wire is susceptible to partial movement of the welding head, causing the welding wire to be subjected to tension. Due to the arrangement of the first extrusion sheet 17 and a pair of second extrusion sheets 18 of the elastic structure, the welding wire can be kept in a centered position. On the one hand, when the welding wire is subjected to tension, the welding wire is squeezed and contacted with the above-mentioned elastic structure, which can play a buffering role and prevent the welding wire from being pulled and scratched and affecting the quality of the product. On the other hand, when the tail of the welding wire is long and swings, the above-mentioned elastic structure can perform elastic reset on the basis of fixing the welding wire.

[0040] like Figure 7 , Fig.11 and Fig.13As shown, a accommodating area 30 is formed between the first side plate 26 and the second side plate 27, an inlet and outlet 25 is formed between the baffle 24 and the arc-shaped plate 28, the upper wire fork 7 includes a fixed plate 21, and a plurality of slots 22 are provided at one end of the fixed plate 21 close to the lower wire clamp 10, and expansion plates 23 of corresponding sizes are fixed and clamped in the plurality of slots 22, the expansion plates 23 include a first side plate 26 and a second side plate 27 that are relatively arranged, and the first side plate 26 and the second side plate 27 are connected at the top ends, and a baffle 24 is hinged at the bottom end of the first side plate 26, wherein the baffle 24 is an arc-shaped structure, and the concave part of the arc-shaped structure faces the accommodating area 30, and the baffle 24 is a one-way flip, and the flipping direction faces the accommodating area 30, so when the vertical movement mechanism 5 drives the upper wire fork 7 to move downward, the welding wire will first contact the baffle 24, causing the baffle 24 to flip inward, and at the same time, the welding wire enters the accommodating area 30 through the inlet and outlet 25, and the welding wire contacts the top wall of the accommodating area 30, so that the accommodating area The receiving area 30 can limit the upper and both sides of the part of the welding wire close to the exposed end, thereby reducing the problem that the part of the welding wire close to the exposed end is easy to bend when it is squeezed; since the baffle 24 is a one-way flip, the baffle 24 cannot be opened outward, and when the upper wire fork 7 is reset upward, the baffle 24 and the accommodating area 30 cooperate to limit the welding wire. During the resetting process, the welding wire fixed between the first extrusion sheet 17 and the second extrusion sheet 18 can be disengaged due to the limiting effect. Subsequently, when the chain mechanism 3 drives the fixed block 9 to move, the subsequent stripping mechanism is conducive to taking out the welding wire in the fixed block 9. Since the upper wire fork 7 and the lower wire clamp 10 are on the same axis, and there is a partial distance between the upper wire fork 7 and the lower wire clamp 10, when the front end of the welding wire is located between the upper wire fork 7 and the lower wire clamp 10, the upper wire fork 7 and the lower wire clamp 10 can keep the welding wire located between the upper wire fork 7 and the lower wire clamp 10 on the same axis, thereby also achieving the effect of keeping the front end of the welding wire straight.

[0041] like Figure 7 and Fig.12 As shown, the bottom end of the second side plate 27 is fixedly connected with an arc-shaped piece 28 of an elastic structure. When the chain mechanism 3 drives the fixed block 9 to move to one side, the blocking piece 24 cannot be opened downward, and the arc-shaped piece 28 is squeezed and deformed. At this time, the diameter of the inlet and outlet 25 increases, so that the welding wire can slide to the inlet and outlet 25 along with the inclined arc-shaped piece 28, and finally slide out through the inlet and outlet 25. Then the chain mechanism 3 continues to drive the welding wire in the fixed block 9 to move toward the direction of the stripping mechanism. At the same time, the arc-shaped piece 28 that has been separated from the squeeze is reset due to the elastic effect, so that the inlet and outlet 25 restores the default diameter; the bottom end of the arc-shaped piece 28 is fixedly connected with a snap ring 29, and a plurality of slots are opened on the side of the fixed plate 21. The first fixed rod 31 and the second fixed rod 32 are fixedly connected in the plurality of slots respectively. The snap ring 29 is sleeved on the second fixed rod 32, and the blocking piece 24 and the arc-shaped piece 28 are jointly sleeved on the first fixed rod 31. The first fixed rod 31 and the second fixed rod 32 are respectively located on opposite sides of the slot.

[0042] like Figure 8 and Fig.10 As shown, the mounting groove 12 passes through a plurality of first wire teeth 13, the clamping member 14 is located in the mounting groove 12 and slides in a limited position, and a screw rod threadedly connected to the assembly block 15 is rotatably connected in the mounting groove 12, one end of the screw rod extends outward and is fixedly connected with a knob, and the screw rod is connected by rotating in the mounting groove 12, wherein the screw rod and the assembly block 15 are threadedly connected. Since the assembly block 15 slides in a limited position in the mounting groove 12, the rotation of the screw rod can be controlled by rotating the knob, so that the assembly block 15 slides in the mounting groove 12, which is convenient for fine-tuning the position of the assembly block 15 and is conducive to production assembly.

[0043] The working principle provided by the present invention is that during the processing, multiple exposed ends of the welding wires after cutting, stripping and other operations are placed in multiple wiring openings 16. This step is a machine or manual operation in the prior art and will not be described in detail here. During the process of placing the exposed ends of the welding wires in the wiring openings 16, the welding wires first contact the protrusions 19. Since the second extrusion sheet 18, the protrusions 19 and the recessed portions 20 are an integrated elastic structure, when the protrusions 19 are squeezed, elastic deformation occurs, so that the welding wires can enter the triangular arrangement area. The elastic structure of the triangular arrangement can clamp the side surfaces of the welding wires at three points, and the protrusions 19 limit the welding wires to prevent them from being squeezed out, so that the welding wires are effectively fixed, thereby solving the problem that when the chain mechanism 3 drives the fixing block 9 to quickly switch positions, the welding wire tail is long and prone to swinging, causing the placed welding wires to swing or even fall off.

[0044] Then the chain mechanism 3 sends the welding wire on the fixed block 9 to the bottom of the upper wire fork 7, and then the transverse movement mechanism 4 drives the clamp end block 8 to move, and sends the USB connector to the preset position, and then the vertical movement mechanism 5 drives the upper wire fork 7 and the welding mechanism 6 to press down in turn to perform the welding work; by setting the first side plate 26 and the second side plate 27 and the arc-shaped plate 28 and the unidirectional rotating baffle 24, when the vertical movement mechanism 5 drives the upper wire fork 7 to move downward, the welding wire will first contact the baffle 24, so that the baffle 24 is turned inward, and at the same time, the welding wire enters the accommodating area 30 through the inlet and outlet 25, and the welding wire contacts the top wall of the accommodating area 30, so that the accommodating area 30 can be close to the exposed end of the welding wire. The upper part and both sides of the part The blocking piece 24 is one-way flipped and cannot be opened outwards. When the upper wire fork 7 is reset upwards, the blocking piece 24 and the accommodating area 30 cooperate to limit the welding wire. When the chain mechanism 3 drives the fixed block 9 to move to one side, the blocking piece 24 cannot be opened downwards and the arc-shaped piece 28 is deformed by being squeezed. At this time, the diameter of the inlet and outlet 25 increases, so that the welding wire can slide to the inlet and outlet 25 along with the inclined arc-shaped piece 28, and finally slide out through the inlet and outlet 25. Then the chain mechanism 3 continues to drive the welding wire in the fixed block 9 to move toward the stripping mechanism for subsequent stripping processing.

[0045] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
