[0002] Tin rings are commonly used as metal solder, and their manufacturing methods include casting and bending. Among them, the existing tin ring forming structure includes the following steps for the tin ring: 1. spirally winding the tin wire, then cutting a section of the spirally wound tin wire, and then extruding the spiral tin wire section into a ring after cutting; 2. bending one end of the tin wire into a semicircular section, then cutting off the semicircular section to obtain a U-shaped tin wire, and then extruding the U-shaped tin wire into a ring.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] The present invention discloses a tin ring forming structure, combined with Figure 1-Figure 2As shown, it comprises: a support 1, on which a first forming assembly 2, a second forming assembly 3, a discharge assembly 4, a wire feed assembly 5 and a needle support assembly 6 are mounted, and wire feeding holes 11 are symmetrically provided on both sides of the support 1, and the wire feeding holes 11 are used for the entry of tin wire;

[0036] Combine Figure 4 As shown, the first molding assembly 2 is provided with a first molding jig 21, and a docking step 210 is formed at the front end of the first molding jig 21. The tin wire enters the docking step 210. The docking step 210 is provided with a first groove 211. The first groove 211 is U-shaped. The docking step 210 is provided with an avoidance groove 212 facing the first groove 211. The left and right sides of the docking step 210 are knife edges 213. The first driver 20 drives the first molding jig 21 to slide in the support 1 with a guide;

[0037] Combine Figure 5 、 Figure 6 As shown, the second molding assembly 3 is provided with a second driver 30 and two second molding jigs 35. The second driver 30 drives the two second molding jigs 35 to move. The second molding jig 35 is provided with a second groove 350 at one end facing the first groove 211. The second groove 350 is arc-shaped. When moving, the two second molding jigs 35 move away from or approach the first molding jig 21 at the same time.

[0038] Combine Figure 8 As shown, the needle support assembly 6 is provided with a needle support bracket 60, and the needle support bracket 60 is installed with a needle support 61. The needle support 61 passes through the support 1. When the first and second molding jigs move away from or close to the needle support 61, the avoidance groove 212 cooperates with the needle support 61;

[0039] Combine Figure 10-14 As shown, the first forming jig 21 cuts off the incoming tin wire 8 and presses the tin wire 8 on the support needle 61 when working, so that the tin wire 8 is formed into a U shape. The second forming jig 21 cooperates with the first forming jig 21 to press the open end of the U-shaped tin wire 8 on the support needle 61 when working, so that the tin wire 8 is formed into a ring shape; the discharge component 4 is used to send out the tin ring 9 on the support needle 61.

[0040] It should be noted that the first actuator 20 and the second actuator 30 are commonly used linear drive components, such as cylinder assemblies and linear motor assemblies. The docking step 210 is used to support the incoming tin wire for subsequent crimping and forming. The support pin 61 is used to bend and discharge the tin wire. Replacing the support pin 61 with different diameters allows the production of tin wires with different inner diameters.

[0041] Specifically, if Figure 2 As shown, a wire feeding assembly 5 is installed on the outside of the wire feeding hole 11 , and the wire feeding assembly 5 is docked with an external wire feeding mechanism. The wire feeding assembly 5 is installed with a wire feeding needle 50 , and the wire feeding needle 50 is inserted into the support 1 .

[0042] Combine Figure 5 、 Figure 6 As shown, the left and right sides of the second driver 30 are rotatably connected to the corner ends of the two swing arms 32, and the free ends of the two swing arms 32 are rotatably connected to the output shaft 31 of the second driver 30. The other free ends of the two swing arms 32 are installed with a limit box 33, and a roller 34 is installed in the limit box 33. The limit box 33 guides the roller 34. The first end of the follower rod 340 passes through the roller 34 and is fixedly connected to the swing arm 32. The second end of the follower rod 340 is fixedly connected to the second forming jig 35, and the support 1 guides the follower rod 340. Figure 2 As shown, the support 1 is provided with a first slide groove 10 running through the left and right sides, and the first forming jig 21 is installed in the first slide groove 10; the top surface of the support 1 is provided with two second slide grooves 12 connected to the first slide groove 10, and the follower rod 340 is guided to move in the second slide groove 12.

[0043] Specifically, combined Figure 7 、 Figure 14 As shown, the discharging component 4 is fixedly connected to the support 1 through a connecting bracket 41. The discharging component 4 is provided with a slide 42. The free end of the slide 42 is provided with a push rod 43. The push rod 43 is formed with an opening 430 at one end facing the outer wall of the support needle 61. The third driver 40 drives the slide 42 to move up and down and enables the push rod 43 to send the tin ring 8 out. The third driver 40 is a commonly used linear drive component.

[0044] Specifically, combined Figure 2-Figure 7 As shown, the support 1 is provided with a first slide groove 10 running through the left and right sides, and the first molding jig 21 is installed in the first slide groove 10; the top surface of the support 1 is provided with a mounting groove 13 connected to the first slide groove 10, and the needle support assembly 6 is installed on the mounting groove 13; the support 1 is provided with a third slide groove 14 running through the upper and lower sides, and the slide 42 is guided to slide up and down in the third slide groove 14; the support 1 is provided with a fourth slide groove 15 connected to the first slide groove 10, and the first molding jig 21 is guided to slide forward and backward in the fourth slide groove 15. Lubrication grooves are provided at the corners of the above-mentioned slide grooves to add lubricating oil to enhance the smoothness of movement. Combined with Figure 3As shown, the top surface or bottom surface of the support 1 is provided with a window 150 connected to the fourth slide groove 15. The window 150 can be used for disassembly of the components of the first molding assembly 2 to facilitate replacement of the jig and maintenance. At the same time, it is also beneficial for the first molding jig 21 to exit to remove the tin wire that failed to be molded.

[0045] Specifically, if Figure 8 As shown, the support needle 61 is divided into a first section 610 and a second section 611 from top to bottom. The diameter of the second section 611 is smaller than that of the first section 610. The first section 610 is used for crimping and bending the tin wire, and the second section 611 is used for detaching the tin ring so that the tin ring is no longer clamped on the support needle 61.

[0046] Specifically, if Figure 9 As shown, a detection component 7 is installed on the lower side of the support 1, and the detection component 7 is provided with a detection bracket 70. The detection bracket 70 is provided with a discharge hole 71 and a proximity sensor 72. The discharge component 4 sends the tin ring on the support needle 61 into the discharge hole 71, and the proximity sensor 72 is used to detect whether there is a tin ring in the discharge hole 71.

[0047] When the tin wire forming is not performed, the states of the first forming jig 21 and the second forming jig 35 in the support 1 are as follows: Figure 10 As shown, they all begin to retreat or complete retreat to wait for the next tin wire feeding, and the first molding jig 21 and the second molding jig 35 are assembled with the support needle 61 to form a molding ring groove.

[0048] After the tin wire 8 is fed to a preset length, the states of the first forming jig 21 and the second forming jig 35 in the support 1 are as follows: Figure 11-12 As shown, the first molding jig 21 starts to move forward, pressing the tin wire 8 onto the support needle 61 so that it bends into a U shape, and at the same time, the tin wire 8 is cut off. During this period, the second molding jig 35 and the discharge assembly 4 do not move, and the push rod 43 is above the tin wire 8 waiting for discharge after molding.

[0049] After the tin wire 8 is formed into a U shape, the states of the first forming jig 21 and the second forming jig 35 in the support 1 are as follows: Figure 12-13 As shown, the forming movement process of the first forming jig 21 is completed, and the second forming jig 35 starts to move forward, pressing the U-shaped tin wire 8 on the support needle 61 to bend it into a ring shape. At the same time, the first forming jig 21 and the second forming jig 35 also further tighten the tin ring 9 to ensure that it is difficult to rebound. During this period, the discharge component 4 does not move, and the push rod 43 is above the tin wire 8 waiting for discharge after molding.

[0050] After the tin wire 8 is formed into the tin ring 9, the first forming jig 21 and the second forming jig 35 are retracted and reset, and the tin ring 9 is formed. Figure 14 As shown, the discharging assembly 4 performs the discharging process, the pushing rod 43 pushes the tin ring 9 on the support needle 61 downward to discharge the material, and then combines Figure 8 As shown, the tin ring 9 is pushed from the first section 610 to the second section 611. At the second section 611, the tin ring is loosened and directly separated from the support needle 61 and enters the Figure 9 In the detection component 7 shown, the tin rings 9 enter the discharge hole 71 of the detection component 7 , and the proximity sensor 72 counts the number of the tin rings 9 that enter the discharge hole 71 .

[0051] To sum up, the structure of the present application can carry out bilateral symmetrical tin wire feeding, and the tin wire can be quickly formed into a loop and discharged. Compared with the traditional crimping loop-forming structure, it is less likely to have material jamming, which meets user needs and improves production efficiency; in terms of structure, compared with the traditional crimping forming tin ring structure, its driver requirements are fewer and can ensure the quality and efficiency of forming, such as: the bilateral side pressure type second forming component, and furthermore, the structure is more streamlined and occupies less volume while meeting the needs; the first forming jig, the second forming jig and the support needle are simpler and more convenient to replace, which can realize rapid product changeover and rapid equipment maintenance, and the moving components are staggered, with less interference and smooth movement; setting the wire feeding needle can quickly match the optimal position of the tin wire on the forming jig to avoid offset, and at the same time, it is also conducive to docking with the external wire feeding mechanism; setting the detection component can facilitate the statistics of output, and at the same time, it occupies less space and does not cause obvious interference with other mechanisms.

[0052] The embodiments described above merely represent one or more embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
