[0002] Irregular shaped products can be seen everywhere in daily life. They generally attract a large number of consumers with their exquisite and fashionable appearance design. When processing such shaped products, most of them are assembled manually, but manual operation brings many defects such as inaccurate assembly positioning, low precision, inability to distinguish deformed parts, and low work efficiency. For example, Figure 1 The product in the figure is a special charging cable, which includes a charging end, a charging interface 103 and a connecting line 102 connecting the charging end and the charging interface 103. The upper and lower covers of the product plastic shell 101 of the charging end are required to be assembled without deformation and zero gap and fixed by UV glue. Since the surface of the product plastic shell 101 is all curved, there is no stable positioning reference, and it is an appearance part (the outer surface is not covered with a silicone sleeve), it is necessary to ensure that there is no deviation in the horizontal plane during the docking assembly to make it meet the appearance requirements of the product. However, the existing assembly method has low work efficiency and is prone to deformation of the product, so it cannot meet the mass production needs of the product. Utility Model Content

[0034] The technical solution in this embodiment will be described clearly and completely below in conjunction with the drawings in this embodiment. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that all directional indications in this embodiment (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", "setting", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Please combine Figures 1 to 6As shown, the molded shell pressing jig provided in one embodiment of the utility model includes a mounting seat 10, a molded shell positioning block 20, a pressing cover 30 and a driving mechanism 40, wherein the molded shell positioning block 20 is arranged on the mounting seat 10, and a positioning groove 21 adapted to the shape of the lower cover of the product molded shell 101 is provided on the molded shell positioning block 20, and a plurality of positioning columns 22 are arranged around the positioning groove 21. A pressing groove 31 adapted to the shape of the upper cover of the product molded shell 101 is provided on the pressing cover 30, and a plurality of positioning holes 32 are arranged around the pressing groove 31. The driving mechanism 40 can drive the pressing cover 30 to contact or approach the molded shell positioning block 20, so that the positioning columns 22 are inserted into the positioning holes 32 one by one, and the pressing groove 31 is docked with the positioning groove 21.

[0040] In the specific assembly process, first place the lower cover of the product plastic shell 101 in the positioning groove 21 according to its own shape and snap the lower cover into place, then apply glue on the edge of the lower cover and place the upper cover on the lower cover, then operate the driving mechanism 40 to drive the pressing cover 30 to move down, so that the positioning posts 22 are inserted into the positioning holes 32 one by one, and the positioning grooves 21 are docked with the pressing grooves 31, so that the upper cover and the lower cover are kept in a pressed state and wait for the glue to dry. In the above embodiment, through the cooperation of the positioning posts 22 and the positioning holes 32, and under the joint action of the multiple positioning posts 22 distributed at intervals, it is ensured that there is no docking deviation between the positioning grooves 21 and the pressing grooves 31 on the horizontal plane when docking, thereby preventing the upper cover and the lower cover after docking and pressing assembly from having deviations on the horizontal plane, so as to improve the overall aesthetics of the product plastic shell 101.

[0041] Moreover, in a preferred embodiment, the first side of the positioning groove 21 is an arc surface 211 and the second side of the positioning groove 21 opposite to the first side is a plane 212. The positioning groove 21 can limit and position the lower cover according to the shape and size of the product, and then cooperate with the pressing groove 31 on the pressing cover 30 to realize the positioning of the upper cover, so that the upper cover and the lower cover of the product plastic shell 101 can be aligned during pressing to ensure the position accuracy, and each position is evenly stressed and has sufficient pressing strength. At the same time, since each groove is adapted to the shape of the product plastic shell 101, in addition to the positioning function, it can also prevent the product plastic shell 101 from being deformed during pressing. Therefore, the upper cover and the lower cover achieve a non-deformation and zero-gap docking assembly, so that the assembly of the product plastic shell 101 is more accurate and reliable and the appearance is more beautiful, and the entire operation process is simple and fast, suitable for mass production.

[0042] In a preferred embodiment, the positioning column 22 is installed on the housing positioning block 20 with a tight fit (specifically, it can be preferably an interference fit) to prevent the positioning column 22 from shifting and ensure the reliability of installation and the accuracy of positioning. And / or, Figure 4 and Figure 5As shown, the positioning posts 22 are all disposed close to the edge of the positioning groove 21 and are evenly arranged according to the maximum outer dimensions of the product plastic shell 101 to limit the product plastic shell 101 360 degrees on a horizontal plane.

[0043] Furthermore, in order to ensure that the positioning post 22 can be better aligned and inserted into the positioning hole 32, the end of the positioning post 22 facing the positioning hole 32 can be made into a spherical surface. Figures 3 to 6 , each corner of the molded shell positioning block 20 is provided with a guide groove 23, and each corner of the press-fit cover 30 is provided with a guide block 33 adapted to the guide groove 23, and the height of the guide block 33 is greater than the distance from the end of the positioning column 22 facing the positioning hole 32 to the docking surface (i.e., the top surface) of the molded shell positioning block 20. Therefore, when the press-fit cover 30 moves toward the molded shell positioning block 20, the guide block 33 will play a guiding role before the positioning column 22, i.e., a coarse adjustment guide, and then the positioning column 22 will be inserted into the positioning hole 32 one by one for fine adjustment guidance. The coarse adjustment guidance of the guide block 33 can reduce the matching errors between the positioning column 22 and the positioning hole 32, so as to extend the service life of the positioning column 22.

[0044] Further, see again Figure 1 , a connecting wire 102 is disposed at one end of the product plastic shell 101, and a lower receiving groove 24 connected to the positioning groove 21 is provided on the plastic shell positioning block 20, and one end of the lower receiving groove 24 extends to the side of the plastic shell positioning block 20 and forms a notch 241, and one end of the connecting wire 102 can be placed in the lower receiving groove 24 and the other end extends outward from the notch 241, so as to adapt to the processing of charging cables with connecting wires 102 of different lengths. Moreover, the groove width of the lower receiving groove 24 is greater than the diameter of the connecting wire 102, so that the connecting wire 102 can be easily taken in and out. In addition, see again Figure 4 and Figure 5 A lower limiting groove 25 is formed between the positioning groove 21 and the lower receiving groove 24. The groove width of the lower limiting groove 25 is smaller than the groove width of the lower receiving groove 24. The connecting line 102 can be engaged in the lower limiting groove 25, so that the placement direction of the product plastic shell 101 can be limited by limiting the connecting line 102, and the product plastic shell 101 can be prevented from turning over or shifting during operation. In addition, the pressing cover 30 is also provided with an upper receiving groove 34 corresponding to the lower receiving groove 24 and an upper limiting groove 35 corresponding to the lower limiting groove 25.

[0045] See again Figure 1 and Figure 2The driving mechanism 40 includes a mounting frame 43 disposed on the mounting seat 10, a telescopic cylinder 41 with one end fixed on the mounting frame 43, and a connecting seat 42 disposed on the free end of the telescopic cylinder 41, and the pressing cover 30 is fixedly mounted on the connecting seat 42. The telescopic cylinder 41 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, as long as it can drive the connecting seat 42 to perform linear reciprocating motion. Alternatively, in other embodiments, the driving mechanism 40 can also be a purely mechanical multi-link motion mechanism.

[0046] In addition, the mounting base 10 includes a base plate 11 and a vertical plate 12 arranged on the base plate 11. A pair of waist-shaped grooves 121 can also be opened on the vertical plate 12. The mounting frame 43 is installed by fasteners (such as bolts and nuts) passing through the waist-shaped grooves 121, so that the installation height of the mounting frame 43 can be adjusted, and then the starting height of the pressing cover 30 can be adjusted, and the stroke of the pressing cover 30 driven by the telescopic cylinder 41 can meet the requirements of aligning and pressing the upper cover and the lower cover.

[0047] In addition to the above embodiments, the molded case pressing jig may also include a slide rail (not shown) provided on the mounting seat 10 (specifically the bottom plate 11) and a slide plate (not shown) capable of sliding on the slide rail, and the molded case positioning block 20 is fixedly mounted on the slide plate. Before docking assembly, the molded case positioning block 20 may be moved to the outermost end of the slide rail to facilitate the installation of the product molded case 101. After the product molded case 101 is placed in the positioning groove 21, the lower accommodating groove 24 and the lower limiting groove 25 and installed in place, the molded case positioning block 20 is pushed in along the slide rail until it abuts against the vertical plate 12, and the pressing cover 30 is aligned with the product molded case 101, so as to facilitate subsequent operations.

[0048] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the protection scope of the present invention.
