Description
Technical Field
[0001] This utility model relates to a watch strap production equipment, specifically a single-axis precision strap assembly machine for watch strap parts. Background Technology
[0002] In the watch strap manufacturing process, the assembly of watch strap components is a crucial and complex step. Traditional watch strap component assembly methods rely partially on manual operation, which has many drawbacks. Manual assembly is inefficient and cannot meet the needs of large-scale production. Furthermore, the stability and precision of manual operation are limited, easily leading to inconsistent assembly quality and a high product defect rate. For example, when assembling watch strap components such as buckles and links, it is difficult for manual labor to ensure the tightness and alignment accuracy of each connection point, affecting the overall aesthetics and performance of the watch strap.
[0003] While existing automated assembly equipment has improved production efficiency to some extent, it also has significant shortcomings. Many pieces of equipment are complex in structure, poorly designed, and bulky, occupying a large amount of production space and incurring high costs, thus increasing production expenses for enterprises. Furthermore, the precision of this equipment often fails to meet the requirements of high-end watch strap production, and it cannot guarantee the accuracy and reliability of assembly when handling high-precision, small-sized watch strap parts. For example, for watch straps using new materials and intricate designs, existing equipment is prone to problems such as part damage and improper assembly during the assembly process.
[0004] Furthermore, existing assembly equipment is poorly adaptable, making it difficult to quickly adjust to meet the production needs of different watch strap styles and specifications. When companies need to launch new watch strap designs, they often need to make large-scale modifications to their equipment or purchase new equipment, which further increases the company's production burden and time costs. Therefore, developing a high-efficiency, high-precision, compact, and highly adaptable watch strap parts assembly equipment is of significant practical importance. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model provides a single-axis precision strap-tapping machine for assembling watch strap parts. The single-axis precision strap-tapping machine includes a support mechanism, a drive mechanism, a strap-tapping assembly mechanism, and a PLC controller mounted on the support mechanism.

[0026] Please see Figure 1This utility model provides an embodiment of a single-axis precision strap-tapping machine for assembling watch strap parts. The single-axis precision strap-tapping machine includes a support mechanism 1, a drive mechanism 2, a strap-tapping assembly mechanism 3, and a PLC controller 4, all mounted on the support mechanism 1. The drive mechanism 2 is located between the strap-tapping assembly mechanism 3 and the PLC controller 4. Both the drive mechanism 2 and the strap-tapping assembly mechanism 3 are electrically connected to the PLC controller 4. The PLC controller 4 uses an advanced programmable logic controller (PLC) as its control core, and, in conjunction with a human-machine interface (HMI), achieves intelligent control of the entire device. The conveyor belt device also includes two sensing mechanisms 5, both of which are electrically connected to the PLC controller 4. When the two sensing mechanisms 5 detect the presence of foreign objects, they transmit electrical signals to the PLC controller 4, which then controls all operations to stop, ensuring the safety of the operators. In this embodiment, the sensing mechanism 5 is a photoelectric switch, model E3F-DS10C4, and the PLC controller 4 is model YTRC-08. The PLC controller 4 has fault diagnosis and alarm functions, and can monitor the operating status of the equipment in real time. When a fault occurs, it promptly issues an alarm signal and displays fault information, facilitating maintenance by the operators.
[0027] Please see Figure 2 The support mechanism 1 includes a base 11, a protective cover 12, a fixed platform 13, and a fixed platform 13 arranged sequentially from bottom to top. The protective cover 12 is fixed to the base 11 and the fixed platform 13 respectively. The support frame 14 is fixed to the upper end face of the fixed platform 13. The PLC controller 4 is fixed to the support frame 14. The two sensing mechanisms 5 are both fixed to the upper end face of the base 11. An opening is provided on the protective cover 12 below the PLC controller 4. The two sensing mechanisms 5 are symmetrically arranged on the protective cover 12 and are respectively located on both sides of the opening.
[0028] Please see Figure 3The drive mechanism 2 includes an electric cylinder 21 and a lifting platform 22 connected to the output end of the electric cylinder 21. The electric cylinder 21 is vertically arranged and fixed to the upper surface of the fixed platform 13 to maintain the stability of the electric cylinder 21. The electric cylinder 21 is located below the PLC controller 4. A fixed base 23 and a pressure plate 24 are arranged below the lifting platform 22. The two ends of the fixed base 23 are fixed to the lifting platform 22 and the pressure plate 24, respectively. Four guide rods 25 are fixed to the upper surface of the lifting platform 22. All four guide rods 25 are installed on the protective cover 12, so the lifting platform 22 can move with the four guide rods. The lifting rod 25 is raised and lowered to ensure the stability of the lifting platform 22 during the lifting process. The electric cylinder 21 can flexibly adjust motion parameters such as speed, acceleration, and stroke according to different working conditions and process requirements, and can achieve complex motion trajectory control. The electric cylinder 21 has a relatively simple structure, few parts, low maintenance cost, long service life, and features high precision, high efficiency, flexible control, convenient maintenance, and good integration. The operation of the electric cylinder 21 drives the pressure plate 24 to move downward to assemble the watch strap parts fixed on the strap assembly mechanism 3, and to perform precise pressing assembly of the watch strap parts.
[0029] Please see Figure 4 The strap assembly mechanism 3 includes a base 31 and a first positioning seat 32 and a second positioning seat 33 fixed to the upper surface of the base 31. The first positioning seat 32 is located on one side of the second positioning seat 33. A cylinder 34 is also fixed to the upper surface of the base 31. The output end of the cylinder 34 is connected to a push plate 35. The push plate 35 is disposed between the second positioning seat 33 and the cylinder 34, and is located below the pressure plate 24. A gap is provided between the second positioning seat 33 and the push plate 35 to accommodate the strap parts to be assembled. The first positioning seat 32, the second positioning seat 33 and the push plate 35 are all horizontally arranged. The push plate 35 is in contact with the base 31, so that the push plate 35 can be mounted on the base 31. The upward translation and the position of the push plate 35 can be changed under the operation of the cylinder 34, thus adapting to the fixing of watch strap parts of different sizes. It can be customized according to the structural characteristics of different styles of watch straps, accurately positioning some small-sized watch strap parts, ensuring the accuracy and reliability of assembly. In addition, it can also realize the rapid replacement of watch strap parts. When different styles of watch straps need to be produced, the mold can be changed in a short time, improving production efficiency. Operators can input various parameters through HMI, such as assembly speed, strap tapping force, etc. The PLC controller 4 forms various formulas based on these parameters, and can quickly change formulas according to different products to precisely control the drive mechanism 2 and the strap tapping assembly mechanism 3.
[0030] Working principle: Please refer to the following again. Figures 1 to 4In the operation of this utility model, the watch strap part is first placed on the upper surface of the base 31, positioned on one side of the first positioning seat 32 and between the second positioning seat 33 and the push plate 35. Then, the cylinder 34 drives the push plate 35 to approach the watch strap part, fixing the watch strap part to the base 31 with the help of the first positioning seat 32, the second positioning seat 33 and the push plate 35. Then, the electric cylinder 21 is driven to move the lifting platform 22, the fixed seat 23 and the pressure plate 24 downward. The pressure plate 24 completes the tapping assembly of the watch strap part on the base 31. Then, the pressure plate 24 separates from the watch strap part, and the cylinder 34 drives the push plate 35 to separate from the watch strap part, so that the assembled watch strap part can be taken out. The above process is controlled by the PLC controller 4, thus making the device highly automated.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
