Description

Technical Field

[0001] This utility model relates to the technical field of Type-C production, and in particular to a welding mechanism for Type-C side solder joints. Background Technology

[0002] The Type-C terminal requires the protective shell to be soldered to the outside. Due to dimensional errors during the production process, there is a gap between the inner side of the protective shell and the outer side of the Type-C terminal, which cannot fit completely. During soldering, it is easy to fail and cause the two to separate, making it impossible to solder them together. At the same time, the relative position between the Type-C terminal and the protective shell needs to be determined according to production requirements, so positioning is required during soldering. Utility Model Content

[0003] One objective of this invention is to provide a welding mechanism for the side solder joints of a Type-C terminal, which can stabilize the relative position between the Type-C terminal and the protective shell, and ensure that the protective shell is in close contact with the Type-C terminal, facilitating laser welding of the side solder joints.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A welding mechanism for Type-C side solder joints includes a welding carrier and two laser welding machines. Two laser welding machines are positioned on either side of the welding carrier. The welding carrier includes a welding base. A rotary pressing cylinder is mounted in the middle of the welding base. A pressure block is vertically connected to the drive end of the rotary pressing cylinder. A placement cavity is provided at the upper end of the welding base. An outer pushing block is provided at the outer end of the welding base. An inner unfolding rod is mounted on the outer pushing block.

Outer clamping seats are mounted on both sides of the placement cavity. A second arc-shaped edge is provided at the outer end of the outer clamping seat. The outer clamping module is connected to the outer side of the outer clamping seat.

[0006] As a preferred technical solution, an outer propulsion cylinder is fixed to the outer side of the welding base, and a swing arm is hinged to the drive end of the outer propulsion cylinder. The middle part of the swing arm swings on the welding base, and the end of the swing arm is hinged to the outer end of the outer propulsion block. A propulsion spring is connected between the outer propulsion block and the inner propulsion block, and a return spring is connected between the inner propulsion block and the welding base.

[0007] As a preferred technical solution, an inner spring is laterally connected between the inner insertion module and the inner push block, an inner bearing is rotatably connected to the lower end of the inner insertion module, and the inner unfolding rod is rollingly connected to the inner bearing.

[0008] As a preferred technical solution, an outer spring is laterally connected between one end of the outer clamping module and the outer side of the inner push block, and an outer bearing is rotatably connected to the other end of the outer clamping module. The outer side of the outer clamping seat is rolledly connected to the outer bearing, and a clamping spring is laterally connected between the outer clamping seat and the welding base.

[0009] As a preferred technical solution, a fixed lower pressure block and a movable lower pressure block are arranged on the outer side of the pressure block along the vertical direction, and a vertical pressure spring is connected between the movable lower pressure block and the upper end of the pressure block.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 8As shown, in this embodiment, a welding mechanism for Type-C side solder joints includes a welding carrier 1 and a laser welding machine 2. Two laser welding machines 2 are located on both sides of the welding carrier 1. The welding carrier 1 includes a welding base 3. A rotary pressing cylinder 4 is installed in the middle of the welding base 3. A pressure block 5 is vertically connected to the drive end of the rotary pressing cylinder 4. A placement cavity 6 is provided at the upper end of the welding base 3. An outer push block 7 is provided at the outer end of the welding base 3. An inner unfolding rod 8 is installed on the outer push block 7. A first arc-shaped edge 9 is provided on both sides of the front end of the inner unfolding rod 8. An inner push block 10 is provided between the welding base 3 and the outer push block 7. An inner insertion module 11 and an outer clamping module 12 are provided on the inner push block 10. The inner side of the inner insertion module 11 is connected to the inner unfolding rod 8. An outer clamping seat 13 is installed on both sides of the placement cavity 6. A second arc-shaped edge 14 is provided at the outer end of the outer clamping seat 13. The outer clamping module 12 is connected to the outer side of the outer clamping seat 13.

[0026] Place the Type-C terminal 32 on the placement cavity 6, cover the Type-C terminal 32 with the protective shell 33, and then move the outer push block 7 towards the placement cavity 6. First, the outer push block 7 also pushes the inner push block 10 to move, and the inner insertion module 11 is inserted into the Type-C terminal 32. At the same time, the outer clamping modules 12 connected to both sides of the inner push block 10 move forward, so that the outer clamping seats 13 press the outer side of the protective shell 33 laterally, so that the inner side of the protective shell 33 is in contact with the outer side of the Type-C terminal 32. When the inner push block 10 moves to the end, the outer push block 7 continues to move forward, and is in the outward push position. The inner unfolding rod 8 on the insert block 7 is inserted between the two inner insert modules 11, causing the inner insert modules 11 to move outward, thereby supporting the inner side of the Type-C terminal 32. Together with the outer clamping seat 13, the Type-C terminal 32 and the protective shell 33 are tightly attached to each other on the side. Then, the downward pressing cylinder 4 is rotated to control the pressing block 5 to move downward and rotate 90° to press on the protective shell 33, so that the protective shell 33 is tightly attached to the Type-C terminal 32 in the vertical direction. Finally, the laser welding machine 2 welds the welding point 34 on the protective shell 33 to the Type-C terminal 32 from the side.

[0027] An external propulsion cylinder 15 is fixed to the outside of the welding base 3. A swing arm 16 is hinged to the drive end of the external propulsion cylinder 15. The middle part of the swing arm 16 swings on the welding base 3. The end of the swing arm 16 is hinged to the outer end of the external propulsion block 7. A propulsion spring 17 is connected between the external propulsion block 7 and the inner propulsion block 10. A return spring 18 is connected between the inner propulsion block 10 and the welding base 3. The external propulsion cylinder 15 controls the horizontal movement of the external propulsion block 7 through the swing arm 16. After the inner propulsion block 10 is pushed to the end, the propulsion spring 17 retracts, and the external propulsion block 7 can move further. After welding is completed, the return spring 18 pushes the inner propulsion block 10 outward.

[0028] An inner spring 19 is laterally connected between the inner insertion module 11 and the inner push block 10. An inner bearing 20 is rotatably connected to the lower end of the inner insertion module 11. The inner unfolding rod 8 is rolledly connected to the inner bearing 20. When the inner unfolding rod 8 is inserted between the two inner insertion modules 11, the inner bearing 20 rolls into contact with the first arc-shaped edge 9 on the inner unfolding rod 8, forcing the inner spring 19 to contract. The inner insertion module 11 is then pushed outward from inside the Type-C terminal 32.

[0029] An outer spring 21 is laterally connected between one end of the outer clamping module 12 and the outer side of the inner push block 10. An outer bearing 22 is rotatably connected to the other end of the outer clamping module 12. The outer side of the outer clamping seat 13 is rolledly connected to the outer bearing 22. A clamping spring 23 is laterally connected between the outer clamping seat 13 and the welding base 3. The inner push block 10 drives the outer clamping module 12 to move forward. The outer bearing 22 rolls into contact with the second arc-shaped edge 14 of the outer clamping seat 13, forcing the clamping spring 23 to contract. The outer clamping seat 13 presses the protective shell 33 from both sides.

[0030] A fixed lower pressure block 24 and a movable lower pressure block 25 are arranged vertically on the outer side of the pressure block 5. A vertical pressure spring 26 is connected between the movable lower pressure block 25 and the upper end of the pressure block 5. Side pressure modules 27 are arranged on both sides of the lower end of the pressure block 5. A side pressure roller 28 is rotatably connected to the front end of the side pressure module 27. A side pressure spring 29 is connected between the side pressure module 27 and the pressure block 5. The rotating lower pressure cylinder 4 controls the pressure block 5 to move down while rotating 90°. The movable lower pressure block 25 first contacts the upper end of the protective shell 33. Affected by the contraction of the vertical pressure spring 26, the pressure block 5 continues to move down until the fixed lower pressure block 24 presses against the protective shell 33, determining the height of the vertical pressure. The side pressure roller 28 starts to contact the outer side of the protective shell 33. The side pressure spring 29 contracts and the side pressure roller 28 rolls down on the outer side of the protective shell 33, pushing the protective shell 33 towards the Type-C terminal 32 and pressing it tightly.

[0031] A shielding cylinder 30 is provided between the laser welding machine 2 and the welding carrier 1. The drive end of the shielding cylinder 30 is vertically connected to a shielding plate 31. When laser welding is not required, the shielding cylinder 30 controls the shielding plate 31 to rise and block the laser welding machine 2.

[0032] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
