[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figures 1 to 6 , is a quick-release fixture structure for watch case assembly according to an embodiment of the utility model, comprising a fixture 10, and a pressure claw assembly 20 elastically mounted on opposite sides of the fixture 10. The fixture 10 is used to carry a watch case 31, and opposite sides of the inner periphery of the watch case 31 are respectively provided with receiving holes 310, and the receiving holes 310 are used to accommodate and install a button 32 and a button spring 33. The top of the watch case 31 corresponding to the receiving hole 310 is also used to connect a welding piece 34, and the welding piece 34 blocks the receiving hole 310, so as to encapsulate the button 32 and the button spring 33 on the watch case 31.

[0029] The fixture 10 includes a carrier platform 11 and a plug-in platform 12 extending downward from the bottom surface of the carrier platform 11. The carrier platform 11 is used to position the carrier case 31. Positioning grooves 13 are respectively provided on opposite sides of the top surface of the carrier platform 11; a stepped hole 14 is provided downwardly corresponding to the middle of each positioning groove 13 on the carrier platform 11, and the stepped hole 14 completely penetrates the carrier platform 11 and the plug-in platform 12, and the stepped hole 14 is used for the pressure claw assembly 20 to pass through. The aperture of the top of the stepped hole 14 is smaller than the aperture of the bottom of the stepped hole 14, and the aperture of the stepped hole 14 is larger than the slot width of the positioning slot 13.

[0030] In this embodiment, the docking station 12 is arranged in a rectangular shape, so that the docking station 12 can be installed on the welding machine in an aligned manner. The rectangular shape provides clear positioning points on the four sides of the docking station 12, which greatly simplifies the steps of alignment and installation. Secondly, the rectangular shape is more stable, which allows the docking station 12 to remain stable during the welding process and is not prone to shaking or shifting, which is crucial to ensuring welding quality and improving production efficiency.

[0031] In this embodiment, the two positioning grooves 13 are located on the same straight line, and the receiving hole 310 is located at one end of each positioning groove 13 .

[0032] The pressure claw assembly 20 includes a T-shaped connecting rod 21 that passes upward from the bottom of the autonomous tool 10, a pressure claw spring 22 that is coaxially sleeved on the T-shaped connecting rod 21, and a pressure claw 23 located above the fixture 10; the T-shaped connecting rod 21 passes through the fixture 10 and is connected to the pressure claw 23 upward. Specifically, the T-shaped connecting rod 21 passes through the stepped hole 14 and is connected to the pressure claw 23 upward.

[0033] Among them, the bottom end of the pressure claw spring 22 abuts the bottom end of the T-shaped connecting rod 21, and the top end of the pressure claw spring 22 abuts the inner wall of the fixture 10 to drive the pressure claw 23 to tightly abut the top surface of the supporting platform 11. The end of the pressure claw 23 is used to extend out of the edge of the top surface of the supporting platform 11 and abut the welding piece 34 to press the welding piece 34 tightly against the watch case 31 to facilitate welding.

[0034] like Figure 3 As shown, the bottom surface of the pressure claw 23 is provided with a positioning protrusion 230 protruding downward, and the positioning protrusion 230 is used to match and embed in the positioning groove 13 to lock the working position of the pressure claw 23, prevent the pressure claw 23 from being displaced during operation, and effectively ensure the alignment accuracy of the watch case 31 and the welding piece 34. Further, the end of the pressure claw 23 is provided with an operation port 24, and the operation port 24 is used to correspond to the welding piece 34 to expose the contact edge (that is, the welding position) of the watch case 31 and the welding piece 34, so as to facilitate the operation of the welding machine, weld the watch case 31 and the welding piece 34 together, and then encapsulate the button 32 and the button spring 33 on the watch case 31.

[0035] Please combine Figure 5 and Figure 6It is understood that in actual operation, the operator first manually pulls up and rotates the pressure claw 23 so that the positioning protrusion 230 is disengaged from the positioning groove 13 and abuts against the top of the positioning groove 13. At this time, the pressure claw spring 22 is in a compressed state and stores elastic potential energy. Subsequently, the operator places the watch case 31 securely on the carrier 11, and sequentially puts the button 32 and the button spring 42 into the receiving hole 310 of the watch case, and then covers the welding piece 34 above the receiving hole 310 to prepare for the subsequent clamping step. Next, the operator manually operates again to reset the pressure claw 23. With the reset of the pressure claw 23, the positioning protrusion 230 is re-embedded in the positioning groove 13. At this time, the pressure claw spring 22 gradually restores its original length and releases the elastic potential energy stored before, driving the T-shaped connecting rod 21 to move downward. Due to the drive of the T-shaped connecting rod 21, the pressing claw 23 is tightly against the carrier 11, and the end of the pressing claw 23 extends out of the edge of the top surface of the carrier 11 to press the welding piece 34, ensuring that the welding piece 34 is firmly pressed on the watch case 31. At this time, the operation port 24 just corresponds to the welding piece 34. Through this series of precise operations, the welding piece 34 can be accurately fixed on the watch case 31, effectively preventing the welding piece 34 from being misplaced, greatly improving the positioning accuracy, and providing a stable and reliable foundation for subsequent welding work.

[0036] The above-mentioned quick-release fixture structure for assembling the watch case has a simple structure and is easy to use. The fixture 10 is elastically connected with a pressure claw 23, and the pressure claw 23 is used to press the welding piece 34, which effectively prevents the welding piece 34 from being misplaced, greatly improves the positioning accuracy, and ensures the welding quality.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
