Description

Technical Field

[0001] This invention relates to the field of welding ring processing technology, and more specifically to equipment for automatically processing welding wire into welding rings. Background Technology

[0002] The solder rings used for high-frequency soldering of electronic expansion valves are typically machined manually. The machining process is as follows: Figure 1 As shown:

[0003] First, manually wind solder wire 1 around the outer circumference of the grooved metal rod 3, ensuring the loops fit tightly together. Then, use a utility knife to cut the solder wire 1 along the groove 2 of the metal rod 3. Next, remove the cut solder ring 4 from one end of the metal rod 3 to obtain an open solder ring 4 as shown in the figure. Finally, flatten the open solder ring 4 before using it for soldering.

[0004] This manual method of processing solder rings is limited by the length of the metal rod, so the above winding, cutting and taking process must be repeated many times to meet the production requirements of each shift. The manual wire winding takes up the time that should be used for welding operations, which seriously reduces production efficiency.

[0005] Moreover, the openings of manually wound welding rings are misaligned and uneven, making them prone to tangling and affecting subsequent usage efficiency.

[0006] In addition, the manual winding process requires the rings to fit tightly together; otherwise, the resulting rings will be of varying sizes, which will affect the welding quality. Summary of the Invention

[0007] This technical solution provides a welding ring processing equipment to at least solve some of the above-mentioned technical problems.

[0008] The welding ring processing equipment provided in this technical solution includes:

[0009] A welding ring processing device, comprising:

[0010] A welding wire feeding mechanism for continuously feeding welding wire;

[0011] A wire feeding mechanism is used to feed welding wire to the wire cutting mechanism and the wire winding mechanism described below.

[0012] A welding wire cutting mechanism is used to cut welding wire to a fixed length.

[0013] The welding wire winding mechanism includes a U-shaped winding mechanism, a left winding mechanism, and a right winding mechanism; the U-shaped winding mechanism is configured to shape the cut welding wire into a U-shape; the left winding mechanism is configured to shape and close the left end of the opening of the U-shaped welding wire; and the right winding mechanism is configured to shape and close the right end of the opening of the U-shaped welding wire.

[0014] The welding ring processing equipment provided by this technical solution uses a wire traction and feeding mechanism to feed the welding wire to the positions of the wire cutting mechanism and the U-shaped winding mechanism. After the wire cutting mechanism cuts the welding wire, the U-shaped winding mechanism shapes the cut welding wire into a U-shape. Then, the left and right winding mechanisms of the welding wire shape and close the left and right ends of the U-shaped welding wire opening respectively, so that the U-shaped welding wire forms a welding ring. Finally, the welding ring is removed from the central axis to achieve automatic feeding. By repeating the above cycle, the welding wire can be automatically and continuously processed into welding rings, thereby replacing the manual operation mode of manually winding welding rings and solving various technical problems existing in the manual operation mode.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In this document, terms such as "upper," "lower," "left," and "right" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, the corresponding positional relationships may change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0030] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the overall structure of the welding ring processing equipment provided in the first embodiment of the present invention.

[0031] As shown in the figure, in one specific embodiment, the welding ring processing equipment provided by the present invention is mainly used for the automatic winding, cutting and unloading of welding wire (e.g., tin welding wire). It is mainly composed of a welding wire feeding mechanism 10, a welding wire introduction and guiding mechanism 20, a welding wire traction and feeding mechanism 30, a welding wire cutting mechanism 40, a U-shaped winding mechanism 50, a welding wire left winding mechanism 60, a welding wire right winding mechanism 70, and a welding ring unloading mechanism 80.

[0032] The welding wire introduction and guiding mechanism 20, the welding wire traction and feeding mechanism 30, the welding wire cutting mechanism 40, the U-shaped winding mechanism 50, the welding wire left winding mechanism 60, the welding wire right winding mechanism 70, and the welding ring unloading mechanism 80 are all centrally arranged on the workbench 100. The welding wire feeding mechanism 10 is located on the side of the workbench 100 and is separated from the workbench 100 by a distance, so that there is enough distance to stretch the welding wire 111 from the coiled form to the straight form.

[0033] Of course, in other embodiments, the welding wire feeding mechanism 10 may also be located on one side of the workbench 100, or on the workbench 100.

[0034] In this embodiment, the welding wire feeding mechanism 10 mainly consists of a welding wire spool 11 and a welding wire spool support frame 12. The welding wire spool 11 is rotatably mounted on the welding wire spool support frame 12 and can rotate on the welding wire spool support frame 12 to continuously output welding wire 111.

[0035] The wire guide mechanism 20 is used to guide the wire 111 output from the wire reel 11 to accurately enter the wire traction and feeding mechanism 30.

[0036] The wire traction and feeding mechanism 30 is used to provide traction force to transport the wire 111 from the wire introduction guide mechanism 20 to the positions of the wire cutting mechanism 40 and the U-shaped winding mechanism 50.

[0037] The welding wire cutting mechanism 40 is used to cut the welding wire 111. When the welding wire traction and feeding mechanism 30 outputs the welding wire 111 to the set length, that is, when the length from the front end of the welding wire 111 to the welding wire cutting mechanism 40 is equal to the circumference of the welding ring, the welding wire cutting mechanism 40 starts to operate, thereby accurately cutting the welding wire 111 and providing a dimensionally stable welding wire blank for subsequent shaping.

[0038] The U-shaped winding mechanism 50 is used to shape the cut welding wire 111 into a U-shape. After shaping, the middle part of the U-shaped welding wire is semi-circular, and the two ends are straight lines that are parallel to each other, with an opening between the two ends. It is a semi-finished product as a whole. It needs to close the opening along the trajectory of the other semi-circle to form a complete welding ring.

[0039] The left winding mechanism 60 is used to shape and close the left end of the opening of the U-shaped welding wire along a quarter circle, and the right winding mechanism 70 is used to shape and close the right end of the opening of the U-shaped welding wire along a quarter circle. After being shaped by the left winding mechanism 60 and the right winding mechanism 70, the welding wire changes from a U-shaped semi-finished product into a circular welding ring 90 with a closed opening.

[0040] The welding ring unloading mechanism 80 is used to automatically unload the shaped welding ring 90 after the welding wire 111 has been processed into a welding ring 90.

[0041] Please refer to Figure 3 , Figure 4 , Figure 3 for Figure 2 A schematic diagram of the wire introduction and guiding mechanism shown in the figure; Figure 4 for Figure 3 The diagram shows a cross-sectional view of the wire introduction and guiding mechanism.

[0042] As shown in the figure, the wire introduction guide part of the wire introduction guide mechanism 20 is generally block-shaped with an L-shaped longitudinal section. The transverse part is provided with several connecting holes to facilitate fixing it to the worktable 100 by screws and other components. The vertical part has a through guide hole 21 that runs through the front and back near the top. The wire 111 led out from the wire spool 11 passes through the through guide hole 21 and enters the wire traction and feeding mechanism 30.

[0043] To facilitate the passage of the welding wire 111 through the guide hole 21, a flared section in the shape of a trumpet is provided at the entrance end of the guide hole 21. In this way, as the diameter of the welding wire spool 11 gradually decreases during processing, the welding wire 111 can adaptively deflect to a certain extent relative to the entrance of the guide hole 21, avoiding bending at the entrance end of the guide hole 21 and affecting normal delivery.

[0044] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the wire feeding and traction mechanism.

[0045] As shown in the figure, the wire traction and feeding mechanism 30 uses a stepper motor (or servo motor) and double rollers to achieve wire traction and feeding.

[0046] In this embodiment, the wire feeding mechanism 30 mainly consists of a stepper motor 31, a driving wheel 32, and a driven wheel 33. The stepper motor 31 is arranged vertically, and the driving wheel 32 is connected to the output shaft of the stepper motor 31. The driving wheel 32 is provided with an annular groove 321 that matches the diameter of the welding wire. The diameter of the driving wheel 32 is relatively large, while the diameter of the driven wheel 33 is relatively small. A spring clamping part 34 is provided on the outer side of the driven wheel 33. The spring clamping part 34 presses the driven wheel 33 against the driving wheel 32 by the spring force, so that the driving wheel 32 and the driven wheel 33 press against each other, forming a space for clamping the welding wire between the driving wheel 32 and the driven wheel 33. The welding wire 111 passes through the space between the driving wheel 32 and the driven wheel 33, and the driving wheel 32 and the driven wheel 33 pull the welding wire 111 by friction to achieve the feeding action.

[0047] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the wire cutting mechanism and the U-shaped winding mechanism.

[0048] As shown in the figure, the U-shaped winding mechanism 50 is provided with a central shaft 51, a welding wire U-shaped stamping part 52 and a first driving device. The welding wire U-shaped stamping part 52 is provided with a first shaping groove 521 corresponding to the central shaft 51. This first shaping groove 521 is semi-circular. The first driving device is used to drive the welding wire U-shaped stamping part 52 to move towards the central shaft 51 so that the cut welding wire 111 is shaped into a U-shape with the central shaft 51 as support through the first shaping groove 521.

[0049] In this embodiment, the first driving device is a first cylinder 53, the welding wire U-shaped stamping part 52 is installed on the first slide rail 54, and the telescopic rod of the first cylinder 53 is connected to the welding wire U-shaped stamping part 52 to drive the welding wire U-shaped stamping part 52 to reciprocate along the first slide rail 54.

[0050] The welding wire cutting mechanism 40 is fixedly connected to the U-shaped winding mechanism 50. The welding wire cutting function can be achieved by the U-shaped winding mechanism 50 and the shearing block 41 working together. The shearing block 41 is fixed at the welding wire fixed length cutting position on one side of the central shaft 51. Its side facing the central shaft 51 can be closely fitted with the side of the welding wire U-shaped stamping part 52, thereby cutting the welding wire 111 through cooperation with the welding wire U-shaped stamping part 52.

[0051] Specifically, the vertical edge on one side of the front end of the welding wire U-shaped stamping part 52 forms a first cutting edge, and the cutting of 41 vertical edges corresponding to the first cutting edge forms a second cutting edge. When the first cylinder 53 drives the welding wire U-shaped stamping part 52 forward and moves towards the central axis 51, the first cutting edge and the second cutting edge first cut the welding wire 111 by mutual misalignment. Then the cut welding wire 111 is pushed towards the central axis 51 by the welding wire U-shaped stamping part 52 and fits against the central axis 51 to achieve U-shaped shaping.

[0052] Please refer to Figure 7 , Figure 8 , Figure 7 This is a schematic diagram of the left-hand winding mechanism for the welding wire; Figure 8 This is a schematic diagram of the right-hand winding mechanism for welding wire.

[0053] As shown in the figure, the left winding mechanism 60 of the welding wire mainly consists of the left punching part 61 of the welding wire and the second driving device. The front end of the left punching part 61 of the welding wire is provided with a second shaping groove 611 at one corner. This second shaping groove 611 is a quarter circle. The second driving device is used to drive the left punching part 61 of the welding wire to move towards the central axis 51 so as to shape and close the left end of the opening of the U-shaped welding wire.

[0054] Specifically, the second driving device is a second cylinder 62, the left punching part 61 of the welding wire is installed on the second slide rail 63, and the telescopic rod of the second cylinder 62 is connected to the left punching part 61 of the welding wire to drive the left punching part 61 of the welding wire to reciprocate along the second slide rail 63.

[0055] The right-hand winding mechanism 70 and the left-hand winding mechanism 60 of the welding wire have similar structures and are symmetrical in structure.

[0056] The welding wire right winding mechanism 70 is mainly composed of the welding wire right stamping part 71 and the third driving device. The front end of the welding wire right stamping part 71 is provided with a third shaping groove 711 at one corner. This third shaping groove 711 is in the shape of a quarter circle. The third driving device is used to drive the welding wire right stamping part 71 to move towards the central axis 51 so as to shape and close the right end of the opening of the U-shaped welding wire.

[0057] Specifically, the third driving device is a third cylinder 72, the right punching part 71 of the welding wire is installed on the third slide rail 73, and the telescopic rod of the third cylinder 72 is connected to the right punching part 71 of the welding wire to drive the right punching part 71 of the welding wire to reciprocate along the third slide rail 73.

[0058] The shaping principle of the left winding mechanism 60 and the right winding mechanism 70 of the welding wire is that the cylinder drives the shaping groove forward, and after contacting the U-shaped welding wire, it shapes and closes the welding wire. Finally, the shaping groove makes the welding wire fit with the central shaft 51, realizing the circular winding of the welding wire 111, that is, forming a welding ring 90.

[0059] In order to ensure that the welding ring 90 can be accurately formed, the center lines of the left winding mechanism 60 and the right winding mechanism 70 can be set at an angle to the center line of the U-shaped winding mechanism 50, and the included angle between the two is greater than 90°, for example, it can be 120°.

[0060] Furthermore, the left wire winding mechanism 60 and the right wire winding mechanism 70 can operate sequentially or simultaneously. If the left wire winding mechanism 60 and the right wire winding mechanism 70 operate simultaneously, processing efficiency can be further improved.

[0061] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the welding ring feeding mechanism.

[0062] As shown in the figure, the welding ring unloading mechanism 80 mainly consists of an unloading cylinder 81 and a Z-shaped connecting rod 82. The unloading cylinder 81 is arranged vertically with its telescopic rod extending upward. The two opposite bending angles of the Z-shaped connecting rod 82 are set at 90°. One end of the connecting rod is connected to the telescopic rod at the upper end of the unloading cylinder 81, and the other end is opened and fitted onto the central shaft 51, and is located above the welding ring 90. The upper end of the central shaft 51 is provided with a central shaft fixing bracket 511 to maintain the stability of the central shaft 51.

[0063] After the welding ring 90 is formed, the unloading cylinder 81 drives the Z-shaped connecting rod 82 to move downward, thereby removing the welding ring 90 from the central shaft 51 and realizing the unloading action of the welding ring 90.

[0064] The working principle of the above-mentioned welding ring processing equipment is as follows:

[0065] First, manually insert the head of the welding wire 111 from the welding wire spool 11 (or coil) into the welding wire guide section;

[0066] Next, the welding wire 111, which is introduced into the guide section by the stepper motor 31 of the welding wire traction and feeding mechanism 30, is pulled into the welding wire winding mechanism by friction through the friction of the two pressed rollers.

[0067] The welding wire winding mechanism consists of three steps: First, the welding wire cutting mechanism 40 and the U-shaped winding mechanism 50 cut the fed welding wire 111 of a specified length and continue to shape it into a U-shape so that it fits tightly against the central shaft 51; Second, after the first step is completed, the welding wire left winding mechanism 60 continues to close the left open end of the U-shaped welding wire to achieve secondary shaping; Third, after the second step is completed, the welding wire right winding mechanism 70 continues to close the right open end of the welding wire to achieve final shaping.

[0068] After the welding wire 111 is formed into a ring according to the above steps, the first cylinder 53, the second cylinder 62, and the third cylinder 72 are gradually reset in sequence.

[0069] Finally, the feeding cylinder 81 drives the Z-shaped connecting rod 82 to remove the welding ring 90 from the central shaft 51 and drop it into the finished product box.

[0070] By repeating the above cycle, the welding wire can be automatically processed into welding rings.

[0071] The above embodiments are merely preferred embodiments of the present invention and are not limited thereto. Based on these, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, the welding wire cutting mechanism 40 and the U-shaped winding mechanism 50 can be designed separately as independent mechanisms; or, the feeding cylinder 81 can use a U-shaped fork to remove the welding ring 90 from the central shaft 51, and so on. Since there are many possible implementation methods, they will not be listed here.

[0072] This invention fully utilizes the relatively soft properties of the welding wire material, employing a stepper motor (or servo motor) and rollers to achieve automatic feeding; it also uses cylinders and arc-shaped grooves for step-by-step shaping, with each step's shaping mechanism consisting of cylinders and arc-shaped shaping grooves, where the arc combination of the shaping grooves is 180°+90°+90°=360°, achieving wire forming into rings; finally, automatic unloading is achieved using a cylinder and ring sleeve pushing and pulling method.

[0073] Compared to manual solder ring processing, this method saves time in the soldering process, significantly improving production efficiency. Furthermore, the solder ring openings are smooth, less prone to tangling, and do not affect subsequent use. In addition, the solder rings processed each time are of uniform size, which helps ensure soldering quality.

[0074] The welding ring processing equipment provided by this invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of this invention. It should be noted that those skilled in the art can make several improvements and modifications to this invention without departing from the principles of this invention, and these improvements and modifications also fall within the protection scope of the claims of this invention.
