DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following description are shown in detail. Of course, they are merely examples and are presented to provide a thorough description of the application, and in no way to limit the application. In addition, the reference numbers and / or letters can be repeated in different examples. Such repetition is for the purpose of simplicity and clarity, and does not indicate the relationship between the various embodiments and / or settings being discussed.

[0035] For the convenience of description, spatial relative terms can be used in the specification to describe the relative position relationship or movement condition of one element or feature relative to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the specification are interpreted accordingly.

[0036] As shown in Figures 1 to 3 and Figure 7 In a first aspect, embodiments of the present application provide a positioning assembly for positioning before assembly of components of a product 10, the product 10 comprising a first part 11 and a plurality of second parts 12, the first part 11 being provided with a plurality of sliding cavities 111, each of the second parts 12 being slidably arranged in each of the sliding cavities 111, the positioning assembly comprising: a base body 40, a first positioning mechanism 20 and a second positioning mechanism 30, the base body 40 comprising a base 41; the first positioning mechanism 20 being fixedly arranged on the base 41 and being used for positioning one sliding cavity 111 and one second part 12; the second positioning mechanism 30 being slidably arranged on the base 41 and being used for positioning one sliding cavity 111 and one second part 12, and after positioning, at least two second parts 12 are fixedly connected.

[0037] By slidably arranging the second positioning mechanism 30, the positioning of different position sliding cavities 111 can be achieved in cooperation with the manufacturing error of the first part 11, and by positioning the second part 12 in cooperation with the position of the sliding cavity 111 of the first part 11, the fixed connection between the plurality of second parts 12 is then performed, thereby avoiding the assembly error between the first part 11 and the second part 12, reducing the occurrence of defective products, improving the utilization rate of parts, and reducing production costs. The present application effectively solves the problem that in the prior art, when the product parts are assembled in linkage, complete machining is required before assembly, resulting in a high defective product rate and affecting production costs.

[0038] It should be noted that Product 10 is mainly used in precision linkage structures in smart terminal products. Through the connection of multiple second parts 12 and the sliding arrangement of the first part 11, it achieves mutual circumferential degree of freedom restriction on the one hand, and ensures simultaneous displacement of multiple points in a propulsion structure with a certain span on the other hand, thereby improving displacement accuracy and increasing the functionality of Product 10. Specifically, Product 10 can be a dual-piston linkage power component, with the matching dual cylinders integrated on the first part 11. The two pistons can simultaneously push out or retract in the same direction.

[0039] like Figures 2 to 4 As shown, in this embodiment, the first positioning mechanism 20 includes a stacked first positioning structure 21 and a second positioning structure 22. The side of the second positioning structure 22 away from the first positioning structure 21 is fixedly connected to the base 41. The second positioning structure 22 is used for positioning the sliding cavity 111, and the first positioning structure 21 is used for positioning the second part 12. The second positioning mechanism 30 includes a stacked third positioning structure 31 and a fourth positioning structure 32. The side of the fourth positioning structure 32 away from the third positioning structure 31 is slidably connected to the base 41. The fourth positioning structure 32 is used for positioning the sliding cavity 111, and the third positioning structure 31 is used for positioning the second part 12. The stacked first positioning structure 21 and second positioning structure 22, as well as the stacked third positioning structure 31 and fourth positioning structure 32, can position the first part 11 and the second part 12 in the same direction. This arrangement provides the same positioning reference, allowing for the simultaneous processing of the first positioning structure 21 and second positioning structure 22, or the third positioning structure 31 and fourth positioning structure 32. This results in smaller assembly errors and higher precision in the assembled product 10.

[0040] It should be noted that the basic dimensions of the first positioning structure 21 are larger than those of the second positioning structure 22, and the basic dimensions of the third positioning structure 31 are larger than those of the fourth positioning structure 32. That is, the first positioning structure 21 and the third positioning structure 31 cooperate with the sliding cavity 111 in the first part 11, and the sliding cavity 111 cooperates with the second part 12, allowing the second part 12 to extend into the sliding cavity 111 of the first part 11, thus avoiding interference. The second positioning structure 22 and the fourth positioning structure 32 can be configured according to the actual situation of the second part 12. For example, when the second part 12 is a solid rod, the second positioning structure 22 and the fourth positioning structure 32 can be configured as suitable clamps, and / or, when the second part 12 has grooves or recesses for positioning, the second positioning structure 22 and the fourth positioning structure 32 can be configured as suitable protrusions or snap-fit ​​pieces. In this way, when positioning the second part 12, the circumferential degrees of freedom of the second part 12 can be restricted as needed to achieve more precise assembly.

[0041] likeFigures 3 to 5 and Figure 7 As shown, in this embodiment, the second positioning mechanism 30 further includes a pushing structure 33, which abuts against the second positioning mechanism 30 to push it along a direction close to the first positioning mechanism 20. The pushing structure 33 is used to adjust the specific position of the second positioning mechanism 30. This arrangement is beneficial for accommodating the sliding cavity 111 of the first part 11 with different errors, enabling better positioning of the first part 11, and also avoiding severe rigid contact that could cause scratches or damage to the inner wall of the sliding cavity 111 during assembly. The pushing structure 33 also adjusts the positioning of the second part 12, reducing the assembly impact caused by manufacturing errors of the first part 11, and providing a reference for the positioning of the second part 12.

[0042] It should be noted that in some alternative embodiments, the pushing structure 33 can achieve planar advancement in the horizontal direction, that is, the second positioning mechanism 30 can be translated in a plane according to actual needs, thereby meeting the multi-directional positioning requirements of the second positioning mechanism 30 and having a wider range of applications, that is, the second positioning mechanism 30 is used for positioning the second part 12.

[0043] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the base 41 is provided with a sliding groove 411, and the second positioning mechanism 30 is slidably disposed in the sliding groove 411. The pushing structure 33 includes a push block 331 and a first elastic member 332, with the first elastic member 332 disposed between the push block 331 and the second positioning mechanism 30. The sliding groove 411 is used to restrict the sliding direction of the second positioning mechanism 30 and to restrict the degree of freedom of the second positioning mechanism 30 in the vertical direction. The sliding groove 411 fixes the adjustment range. Under the condition of adapting to the error of the first part 11, it is possible to determine the defective product when the first part 11 has a large error. This design not only reduces the inspection of the processing quality of the first part 11, but also makes the structure more compact. The push block 331 is slidably disposed on the side of the positioning component. When in use, the second positioning mechanism 30 can be pushed inward by manual pressing to meet the horizontal position adjustment. The first elastic element 332 is provided to apply elastic force. This avoids rigid contact between the first part 11 and the positioning mechanism due to the pushing force generated by the push block 331 when assembling the first part 11 with the two positioning mechanisms, which would cause scratches or damage to the positioning mechanism or the first part 11.

[0044] Further, the first elastic member 332 is arranged to achieve eccentric positioning. Specifically, the first positioning mechanism 20 is provided with a limiting structure. After the first part 11 is installed, the outer wall of the first part 11 abuts against the limiting structure, and the inner wall of the first sliding cavity 111 close to the limiting structure abuts against the first positioning mechanism 20. At this time, the first part 11 is in a determined position. At this time, the pushing structure 33 is used to apply a pushing force, so that the second positioning mechanism 30 abuts against the side of the second sliding cavity 111 close to the first sliding cavity 111. At this time, the positioning mechanism and the sliding cavity 111 are in the same eccentric cooperation. This cooperation mode is similar to an ideal assembly state, that is, the positional relationship between the first positioning mechanism 20 and the second positioning mechanism 30 is the same as the positional relationship between the first sliding cavity 111 and the second sliding cavity 111, and the positional relationship between the first part 11 and the second part 12 is also the same, so that the positioning between the first part 11 and the second part 12 reaches the most suitable state.

[0045] It should be noted that, as shown in Figure 3 and Figure 4 , in order to limit the freedom of the second positioning mechanism 30 in the vertical direction, the embodiment further provides a limiting plate body 414, which covers the sliding groove 411 and is detachably connected with the base 41. In this way, the vertical movement during pushing can be avoided, the accuracy of the positioning process is ensured, and the sliding between the first part 11 and the second part 12 caused by the movement is reduced.

[0046] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 6 , in the technical solution of the embodiment, the sliding cavity 111 is a cylindrical cavity, the second part 12 is a cylindrical structure, the first positioning structure 21, the second positioning structure 22, the third positioning structure 31 and the fourth positioning structure 32 are all cylindrical positioning columns, and the concentricities of the first positioning structure 21 and the second positioning structure 22 are the same as those of the third positioning structure 31 and the fourth positioning structure 32. The cylindrical cavity and the cylindrical structure are more conducive to manufacturing and cooperation, can reduce other forces caused by the arrangement of the structures, and the cylindrical surface is more conducive to bearing the radial force generated during assembly. The first positioning structure 21 and the second positioning structure 22 can be produced by using an integral molding manufacturing method, so that the concentricity accuracy can meet the requirements. The third positioning structure 31 and the fourth positioning structure 32 have the same arrangement principle. Such an arrangement can reduce the positioning error between the first part 11 and the second part 12 caused by the positioning process, and thus the manufacturing accuracy is ensured.

[0047] It should be noted that when the positioning process of the first part 11 adopts eccentric positioning, the positioning of the two second parts 12 is also performed according to the position difference of the eccentricity of the positioning mechanism at this time, and the fit between the two second parts 12 and the first part 11 after the connection is completed is the same, and a large assembly error is not generated, and after the assembly of the product 10 is completed, accurate fit can also be achieved.

[0048] As shown in Figure 2 and Figure 6 In the technical scheme of the embodiment, the product 10 further comprises a third part 13, and the base body 40 further comprises a cover body 42, the cover body 42 is detachably connected with the base 41, the third part 13 has a locking state with the cover body 42, and in the locking state, the third part 13 is fixedly connected with the at least two second parts 12. The third part 13 is arranged to directly connect the two second parts 12, and is arranged through the cover body 42, so that after the positioning and assembly of the first part 11 and the second part 12 are completed, the connection of the second part 12 is fixed, and the arrangement ensures the accuracy of the assembly. The arrangement of the cover body 42 can satisfy the positioning and installation of the third part 13, and the fixed connection of the third part 13 and the second part 12 is completed in the locking state.

[0049] It should be noted that the fixed connection between the third part 13 and the second part 12 can be achieved by welding, or can be achieved by glue dispensing.

[0050] As shown in Figure 5 In the technical scheme of the embodiment, the cover body 42 is provided with a clamping groove 421 matched with the third part 13, and a connecting piece 422 detachably connected with the third part 13 is arranged in the clamping groove 421 to fix the third part 13. The clamping groove 421 and the connecting piece 422 are arranged for positioning of the third part 13, the clamping groove 421 can achieve positioning, and the connecting piece 422 can ensure that the third part 13 does not fall off from the clamping groove 421. Specifically, the third part 13 is made of a material that can be magnetically attracted, and the connecting piece 422 is not fixedly provided with a magnetic attraction part in the clamping groove 421. Such an arrangement saves the arrangement position of the connecting piece 422 and does not interfere with the side of the third part 13 away from the clamping groove 421. When positioning, the third part 13 can be positioned and matched by being fitted into the clamping groove 421. Further, when the positioning of the first part 11 and the second part 12 is performed by using eccentric positioning, the third part 13 can also be positioned in a relatively eccentric manner, that is, the clamping groove 421 is arranged as a strip-shaped groove, one end of the third part 13 abuts one end of the groove, and the abutting end is one end matched with the first positioning mechanism 20. Such an assembly precision is higher and can effectively reduce the assembly error.

[0051] As shown in Figures 1 to 5As shown, in the technical scheme of the embodiment, the cover 42 further comprises a pressing plate 425, the pressing plate 425 is provided with a avoiding slot 426, through which the third part 13 and the second part 12 are fixedly connected. Specifically, the third part 13 is provided with a connecting hole 131 matched with the second part 12, the second part 12 adopts a cylindrical structure, when the cover 42 is locked, the connecting hole 131 is located below the avoiding slot 426, and the inner wall of the connecting hole 131 and the inner wall of the second part 12 are welded by means of laser welding from the avoiding slot 426 through the welding laser. Such a connection mode is reliable, the fixed connection effect is good, and after positioning at multiple positions, welding is performed, which ensures that the assembly of the product 10 will not be deformed, and the quality of the final product is better.

[0052] As shown in Figure 4 and Figure 5 As shown, in the technical scheme of the embodiment, the cover 42 is made of a magnetically attractable material, the base 41 is provided with one or more magnetic attraction structures 412, and the cover 42 and the base 41 are provided with a buffer structure 413. Such a setting can realize the locking of the cover 42 and the base 41, and the structure is simple and reliable in function, the locked structure is stable, and it is more conducive to the fixed connection of the third part 13 and the second part 12. The buffer structure 413 plays a buffering role, reduces the direct force during locking, protects the cover 42 and the base 41 to a certain extent, and the buffer structure 413 also has a sealing effect after being extruded, which can prevent water vapor and dust from invading the magnetic attraction structure 412 and affecting the locking effect of the magnetic attraction.

[0053] Specifically, the buffer structure 413 is an annular rubber material fixedly arranged in the mounting groove 429 of the cover 42, and the cover 42 is provided with a containing groove corresponding to the position of the mounting groove 429. Such a setting can guide the specific deformation of the buffer structure 413 and avoid affecting the cover 42 or the base 41 at other positions. Further, the magnetic attraction structure 412 and the buffer structure 413 are both provided in multiple, respectively surrounding, specifically four, respectively arranged in the opposite four corners of the base 41. Such a setting has a better locking effect and will not produce a phenomenon of warping that affects positioning.

[0054] As shown in Figure 4 and Figure 5As shown, in the technical scheme of the embodiment, the cover 42 is provided with a pressing block structure 423 and a second elastic member 424 connected thereto, the second elastic member 424 abuts against the bottom of the cover 42 and the pressing block structure 423 respectively, and when the cover 42 is attracted, one end of the pressing block structure 423 away from the second elastic member 424 abuts against the first part 11. The pressing block structure 423 is arranged to abut against the first part 11 during locking, which on one hand fixes the first part 11 after positioning, and on the other hand facilitates positioning detection, and when the abutment fails, the cover 42 and the base 41 cannot be tightly combined, indicating that the positioning of the product 10 fails, so as to stop assembly in time. The second elastic member 424 is arranged to push the pressing block structure 423, which plays a role of buffering and pressure maintaining, avoiding the phenomenon that the first part 11 is damaged due to excessive abutment of the pressing block structure 423.

[0055] In some alternative embodiments, the pressing block structure 423 can also be arranged as a clamping structure, that is, the pressing block structure 423 can be clamped with the first part 11, which can further facilitate positioning detection and limit the cooperation of the external structure of the first part 11, so as to ensure that the size of the product does not deviate too much.

[0056] It should be noted that the base 41 is further provided with at least one positioning column 415 arranged in the vertical direction, and the cover 42 is provided with a first positioning groove 427 corresponding to the positioning column 415, the positioning column 415 and the first positioning groove 427 are gap-fitted, and when the cover 42 is locked, the positioning column 415 can play a guiding role and perform preliminary positioning, avoiding excessive magnetic attraction force of the magnetic attraction structure 412 and causing assembly failure. Further, two positioning columns 415 can be arranged, one of which is a cylindrical column, and the other is an elliptical column or a column capable of limiting the circumferential degree of freedom, and the positioning of the two positioning columns 415 is more accurate, one of which is a cylindrical column for preliminary positioning, and the other is a column capable of limiting the circumferential degree of freedom, which can reduce the play caused by gap fitting and further improve the accuracy of the cover 42 during locking. Further, corresponding to the cylindrical column, the cover 42 is provided with a second positioning groove 428, which is a long hole-shaped positioning groove, and the positioning column 415 can slide along the length direction of the long hole, so as to adjust the position of the other positioning column 415 which is an elliptical column or a column capable of limiting the circumferential degree of freedom, and then complete assembly, which has a certain guiding effect and is beneficial to assembly.

[0057] In a second aspect, the embodiments of the present application provide an assembling device, the assembling device comprising a positioning assembly and a processing assembly, the positioning assembly is the positioning assembly described above, and the processing assembly cooperates with the positioning assembly to position and assemble the product 10. By using the positioning assembly described above, the positioning between the components of the product 10 is accurate, the assembling effect is better, the yield is higher, the generation of defective products is reduced, and the production cost is reduced. The processing assembly can be a laser welding device.
