Description

Technical Field

[0001] The utility model relates to the field of watchband assembly, in particular to a watchband particle assembly jig. Background Art

[0002] There are many types of watch straps, which are generally divided into two categories. One is made of soft material in one piece, and the other is a bamboo strap, which is made of multiple watch parts connected by spring ears.

[0003] The volume of the spring ear is relatively small. When assembling, you need to squeeze both ends at the same time to make the two ends shrink inward. The manual assembly process is to squeeze the two ends of the spring ear with fingertips. This assembly method is difficult and inefficient, and it will also cause pain to the fingertips. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a watch band particle assembly jig, which replaces the method of squeezing the two ends of the spring ears with fingertips, reduces the assembly difficulty and improves the assembly efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a watch strap particle assembly jig, characterized in that a pair of pressing parts that can approach each other are provided on the assembly table, and the two ends of the raw ears in the watch material are squeezed into the interior of the raw ears by the two pressing parts moving towards each other.

[0006] Furthermore, an assembly area for positioning the surface material is formed on the assembly table, so that the surface material cannot be offset.

[0007] Furthermore, the assembly area is an assembly table surface on which at least one pair of positioning tables are provided, and the positioning tables abut against two sides of the surface material.

[0008] Furthermore, it also includes a sliding mechanism for driving the pressing part to move. An opening is reserved on the surface of the assembly table, and the pressing part is connected to the movable part of the sliding mechanism through the opening.

[0009] Furthermore, the assembly platform has a cavity with open structures on both sides, the sliding mechanism corresponds to the open structure, and has a direction of entering the assembly platform from the open structure and exiting from the assembly platform, and a pressing part passing through the bar-shaped through hole is provided on the movable part of the sliding mechanism.

[0010] Furthermore, the sliding mechanism includes a slider, a slide rail, and a cylinder. The cylinder and the slide rail are arranged on the table part of the fixture. The slider is slidably connected to the slide rail, and the pressing part is arranged on the slider.

[0011] Furthermore, the pressing part and the slider are snap-fitted together, the mounting groove reserved on the slider has a step, and the portion of the pressing part in the mounting groove has a shape corresponding to the step.

[0012] Furthermore, the pressing portion is a pressing piece maintained in a vertical posture.

[0013] Beneficial effects of the utility model:

[0014] The utility model mainly adds a pair of movable pressing parts on the assembly table, and the pressing parts can be moved closer to each other so that the two ends of the raw ears are squeezed into the inside, replacing the way of squeezing the two ends of the raw ears with fingertips. For small-volume components such as surface materials, the special design of the utility model is more flexible than the use of fingertips, and it is easier to squeeze the two ends of the raw ears. The problem of reduced assembly efficiency caused by reduced assembly stability due to fingertip pain is thoroughly solved. At the same time, the step of pressing with fingertips is replaced, so that the overall assembly difficulty is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the specification, references to "one embodiment", "an embodiment" or "some embodiments" mean that a particular feature, structure or element described with reference to the embodiment is included in at least one embodiment of the subject matter being described. Thus, sentences in the specification saying "in one embodiment" or "in an embodiment" or "in some embodiments" do not necessarily refer to the same embodiment or embodiments. The particular features, structures or elements may be further combined in any embodiment in a suitable manner.

[0023] The watch strap particle assembly jig of this embodiment is used as an auxiliary part in the manual assembly process to reduce the difficulty of assembly. The assembly object is a watch strap with a bamboo-jointed structure, which is composed of multiple watch materials connected together by a spring ear 1c.

[0024] Since the spring ear 1c is a prior art and is common knowledge in the field, and is not a structure that needs to be improved in the present invention, its specific structure will not be described in detail.

[0025] like Figure 1 As shown, the structure of the surface material 1 is formed by connecting nodes 1b on both sides of the connecting portion 1a.

[0026] Before assembly, it is necessary to install the spring ears 1c in the holes reserved on both sides of the front end of the connecting part 1a.

[0027] The jig of the present invention is mainly used to replace the process of squeezing the raw ear 1c by fingertips.

[0028] like Figure 2-7 As shown, the fixture includes an assembly table 2 and a pair of sliding mechanisms 3. The assembly area set on the assembly table 2 can contact the outside of the node 1b at the same time to prevent the surface material 1 from shifting left and right. The connecting portion 1a located outside the assembly area corresponds to the strip opening 2a on the assembly table 2. The assembly table 2 has a cavity with open structures on both sides. The sliding mechanism 3 corresponds to the open structure and has a direction of entering the assembly table 2 from the open structure and exiting from the assembly table 2. The movable part of the sliding mechanism 3 is provided with a pressing portion 4 passing through the strip opening 2a, and the side surfaces of the pressing portion 4 correspond to the two ends of the raw ear 1c. In short, the pressing portion 4 is used to push the two ends of the raw ear 1c, instead of the manual fingertip pressing method.

[0029] It is not difficult to see that the design of the above structure is specifically used to assist in the assembly of the watch strap. Fingertip pressure often causes pain, which weakens the stability of the assembly process. Therefore, the problems of low production efficiency and difficult assembly are solved.

[0030] The assembly area is a surface of the assembly table 2, and at least a pair of positioning tables 2b is provided. The surface material 1 is located between the two positioning tables 2b, and the two nodes 1b are positioned by the positioning tables 2b.

[0031] The sliding mechanism 3 comprises a cylinder 3a, a slider 3b and a slide rail 3c. The cylinder 3a and the slide rail 3c are arranged on the table part belonging to the jig. The slider 3b is slidably connected with the slide rail 3c. The pressing part 4 is arranged on the slider 3b.

[0032] The pressing part 4 and the slider 3b are connected by a snap-fit ​​connection, which has the advantage of simple assembly. Specifically, the mounting groove 5 reserved on the slider 3b has a step 5′, and the part of the pressing part 4 in the mounting groove 5 has a shape corresponding to the step 5′. The two cooperate to ensure the connection stability between the pressing part 4 and the slider 3b.

[0033] In some embodiments, four positioning platforms 2b are provided to ensure that the assembled surface material 1 in the assembly area is in a vertical straight line.

[0034] The pressing portion 4 is a pressing member maintained in a vertical posture.

[0035] Specific installation process:

[0036] Under the action of the pressing piece, the two ends of the ear 1c are retracted inward. At this time, a pair of nodes 1b of the new table material 1 to be assembled are attached to the upper edge of the side of the connecting part 1a corresponding to the ear 1c, and a force is applied by the fingertips to move the new table material 1 toward the pressing piece. At the moment when the cylinder 3a is depressurized and the pressing piece retreats and resets, the node 1b of the new table material 1 quickly slides into the two sides of the connecting part 1a, and the two ends of the ear 1c are inserted into the mounting holes reserved on the new node 1b due to rebound, forming an assembly between the table materials 1.

[0037] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
