Description

Technical Field

[0001] This utility model relates to the field of wrist cord heat fusion technology, and in particular to a wrist cord welding device. Background Technology

[0002] In the existing wristband processing industry, the welding process is an important step in connecting the two ends of the cut wristband. Traditional welding methods usually rely on manual operation. Specifically, the operator needs to manually place the cut end of the wristband in a predetermined position and manually pull the welding head of the welding device to perform heat fusion connection. This manual positioning and welding method has certain limitations.

[0003] First, manual operation inevitably introduces errors, which may cause asymmetry at both ends of the wrist strap after welding, i.e., the lengths of the left and right sections are inconsistent, affecting the appearance quality and performance of the product. Second, manual operation is inefficient and cannot meet the pace requirements of large-scale production, while also increasing labor costs. In addition, it is not easy to maintain stable temperature and pressure during the welding process manually, which may lead to unstable welding quality, further affecting the durability and reliability of the wrist strap.

[0004] Therefore, it is imperative to redesign a wrist cord welding device. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, this utility model provides a wrist rope welding device, which aims to solve the problems of large positioning error, inconsistent lengths of the left and right sections of the product and low efficiency caused by manual operation of wrist rope welding in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wrist cord welding device, comprising a machine base, wherein a wrist cord positioning lower mold, a wrist cord stacking positioning assembly, and a welding assembly are configured on the machine base. The wrist cord positioning lower mold is located on one side of the wrist cord stacking positioning assembly. A welding mounting hole is provided in the middle of the machine base. The wrist cord stacking positioning assembly includes a positioning frame and a welding buffer telescopic rod. The welding buffer telescopic rod includes a positioning rod and a wrist cord positioning head sleeved on the upper end of the positioning rod. The wrist cord positioning head is connected to the positioning rod by a spring. The positioning rod is mounted on the positioning frame. The wrist cord positioning head passes through the welding mounting hole and protrudes above the machine base. A wrist cord stacking groove is provided in the middle of the upper end of the wrist cord positioning head. The welding assembly is located behind the welding mounting hole, and the welding head at the output end of the welding assembly is adapted to the wrist cord stacking groove.

[0007] Based on the above, the beneficial effects of a wrist strap welding device are that it solves the problems of large positioning errors, inconsistent lengths of the left and right sections of the product, and low efficiency caused by manual wrist strap welding in the prior art; mainly reflected in:

[0008] 1. This utility model uses the cooperation of the wrist rope positioning lower mold and the wrist rope superimposed positioning component to manually position the wrist rope body in the wrist rope positioning lower mold and superimpose the two cut ends to be welded in the wrist rope superimposed groove at the upper end of the wrist rope positioning head. This ensures that the two cut ends of the wrist rope can be accurately aligned during welding. This positioning effectively reduces the error caused by manual operation and ensures the consistency of the length of the left and right sections of the wrist rope after welding, thereby improving the appearance quality of the product.

[0009] 2. This utility model uses a downward-pushing cylinder to drive the sliding frame to move along the sliding track, quickly and accurately delivering the heating element and welding joint to the welding position, greatly accelerating the welding speed, improving the overall efficiency of the production line, and reducing labor costs;

[0010] 3. This utility model uses a wrist cord positioning head connected to the positioning rod via a spring, which provides a certain buffer height when the welding joint is pressed down for welding, preventing the welding joint from being damaged due to excessive pressure.

[0011] Furthermore, the welding assembly includes a welding frame, a push cylinder, a sliding frame, and a heating element. The push cylinder is disposed at the upper end of the welding frame. The sliding frame has a sliding rail on the side near the wrist strap stacking and positioning assembly. The sliding frame is disposed on the output end of the push cylinder and is slidably engaged with the sliding rail. The heating element is disposed at the bottom end of the sliding frame, and the welding joint is disposed at the bottom end of the heating element.

[0012] Based on the above, the push cylinder is positioned at the upper end of the welding frame, and the sliding frame is connected to the output end of the push cylinder. Its beneficial effect is to ensure that the welding joint can accurately descend to the predetermined welding position along a straight path, eliminating the positional deviation that may be introduced by manual operation, and ensuring the consistency and accuracy of each welding.

[0013] Furthermore, the wrist strap stacking groove is a V-shaped inner arc groove, and the bottom end of the welding joint is provided with a semi-arc structure. The semi-arc structure is inserted into the V-shaped inner arc groove and cooperates with the lower arc part of the bottom end of the V-shaped inner arc groove to complete the welding and forming of the two cut ends of the wrist strap.

[0014] Based on the above, the advantages of using a V-shaped inner arc groove structure for the wrist cord overlapping groove are that it ensures that the two cut ends of the wrist cord are accurately overlapped during welding, reduces the need for manual adjustment, lowers the difficulty of operation, and significantly improves the consistency of the welding position; the semi-arc structure set at the bottom of the welding joint can be perfectly embedded in the V-shaped inner arc groove, so that the welding joint and the cut end of the wrist cord are in close contact, which increases the effective contact area of ​​welding, ensures that heat can be evenly transferred to the wrist cord material, thereby achieving a more solid and smooth welding effect.

[0015] Furthermore, the fusion joint has a V-shaped insertion structure.

[0016] Based on the above, the beneficial effect of the V-shaped insertion structure is its compatibility with the V-shaped inner arc groove.

[0017] Furthermore, a temperature sensor is also provided inside the heating element.

[0018] Based on the above, the beneficial effect of the temperature sensor is to monitor the welding temperature of the welding joint supplied by the heating element, preventing it from being too low or too high.

[0019] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0027] like Figures 1-6As shown, a wrist strap welding device includes a machine base 1. The machine base 1 is equipped with a wrist strap positioning lower mold 2, a wrist strap stacking and positioning assembly 3, and a welding assembly 4. The wrist strap positioning lower mold 2 is located on one side of the wrist strap stacking and positioning assembly 3. A welding mounting hole 11 is provided in the middle of the machine base 1. The wrist strap stacking and positioning assembly 3 includes a positioning frame 31 and a welding buffer telescopic rod 32. The welding buffer telescopic rod 32 includes a positioning rod 321 and a wrist strap positioning head 3 sleeved on the upper end of the positioning rod 321. 22. The wrist strap positioning head 322 is connected to the positioning rod 321 by a spring. The positioning rod 321 is mounted on the positioning frame 31. The wrist strap positioning head 322 passes through the welding mounting hole 11 and protrudes above the machine base 1. A wrist strap stacking groove 3221 is provided in the middle of the upper end of the wrist strap positioning head 322. The welding assembly 4 is located behind the welding mounting hole 11, and the welding head 41 at the output end of the welding assembly 4 is adapted to the wrist strap stacking groove 3221.

[0028] The welding assembly 4 includes a welding frame 42, a push cylinder 43, a sliding frame 44, and a heating element 45. The push cylinder 43 is disposed at the upper end of the welding frame 42. The sliding frame 44 is provided with a sliding rail 441 on the side near the wrist strap stacking and positioning assembly 3. The sliding frame 44 is disposed on the output end of the push cylinder 43 and is slidably engaged with the sliding rail 441. The heating element 45 is disposed at the bottom end of the sliding frame 44, and the welding joint 41 is disposed at the bottom end of the heating element 45.

[0029] The wrist cord stacking groove 3221 is a V-shaped inner arc groove. The bottom end of the welding joint 41 is provided with a semi-arc structure 411. The semi-arc structure 411 is inserted into the V-shaped inner arc groove and cooperates with the lower arc part of the bottom end of the V-shaped inner arc groove to complete the welding and forming of the two cut ends of the wrist cord.

[0030] The fusion joint 41 has a V-shaped insertion structure.

[0031] A temperature sensor is also provided inside the heating element 45.

[0032] In summary, the specific implementation of this utility model is as follows: First, the wrist rope to be processed is placed in the wrist rope positioning lower mold 2 on the machine 1. Then, the operator carefully stacks the two ends of the wrist rope that need to be welded and puts them into the wrist rope stacking groove 3221 at the upper end of the wrist rope positioning head 322 in the wrist rope stacking positioning assembly 3. Since the groove is designed as a V-shaped inner arc groove, it can effectively ensure that the two cutting ends are precisely aligned during welding, thereby reducing the need for manual adjustment and reducing the error caused by manual operation.

[0033] After the cut end of the wrist strap is correctly placed, the heating element 45 makes the welding joint 41 reach the preset temperature. The downward push cylinder 43 of the welding assembly 4 drives the sliding frame 44 to move linearly along the sliding track 441. The welding joint 41 is inserted into the wrist strap stacking groove 3221 to weld the wrist strap. At the same time, the wrist strap positioning head 322 is slightly buffered downward by the spring on the positioning rod 321 to prevent the welding joint 41 from being damaged during welding.

[0034] During the welding process, the temperature sensor inside the heating element 45 continuously monitors the welding temperature to prevent excessively low or high temperatures from affecting the welding quality. After the welding joint 41 is welded, the push cylinder 43 drives the sliding frame 44 to retract, causing the welding joint 41 to exit from the wrist rope stacking groove 3221. Due to the spring action inside the welding buffer telescopic rod 32, the wrist rope positioning head 322 returns to its original position, ready for the welding operation of the next wrist rope.

[0035] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
