DETAILED DESCRIPTION

[0019] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be accurately conveyed to those skilled in the art. It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0020] Embodiment 1

[0021] Referring to Figure 1 , Figure 2 , Figure 3 As shown in the drawings, the X-axis, Y-axis and Z-axis are perpendicular to each other. The present embodiment provides a shell assembly device, which comprises a rack 10, and a shell support module 1 for carrying a shell 4 to be assembled, which is alternatively moved between a receiving position 101 and a pressing position 102 relative to the rack 10. For example, the shell support module 1 is alternatively moved between the receiving position 101 and the pressing position 102 on the rack 10 by a linear driving module, which comprises, for example, a linear driver (air cylinder, oil cylinder, linear motor, etc.), a guide rail pair (such as a linear guide rail), a guide rod and a guide sleeve.

[0022] The shell assembly device further comprises a small part assembly module 2 provided on the shell support module 1 and used for lifting the small part 5 to be assembled upward, an elastic positioning centering assembly 11 provided on the shell support module 1 and matched with the shell 4 to be assembled, a side pushing correction clamping assembly 12 provided on the shell support module 1 and at least partially distributed on opposite sides of the shell 4 to be assembled, and a heating and pressing module 3 located at the pressing position 102 and used for contacting and heating the shell 4 to be assembled downward.

[0023] The elastic positioning centering assembly 11 and the side pushing correction clamping assembly 12 are used for positioning and correcting the shell 4 to be assembled, lifting the small part to the inner wall of the shell 4 to be assembled by the small part assembly module 2, and completing the assembly by contacting and heating the shell 4 to be assembled by the heating and pressing module 3.

[0024] The side pushing correction clamping assemblies 12 on both sides are symmetrically or staggeredly distributed with a center line, and the elastic positioning centering assembly 11 is located on the center line. The side pushing correction clamping assemblies 12 on both sides and the elastic positioning centering assembly 11 located on the center line form a triangular distribution, thereby realizing the effects of one-point centering positioning, two-side opposite clamping and three-way correction, avoiding the problem of large fluctuation of the relative position and size of the small part and the shell cavity due to the use of single-side limiting, and improving the product assembly yield.

[0025] Preferably, in combination with Figure 1、 Figure 3 、 Figure 6 and Figure 7 As shown in

[0026] The shell supporting module 1 has a clearance for the positioning pin 112 to pass through. Since the driving force of the elastic member 111 is small, the driving mode of the elastic member 111 makes the positioning pin 112 match the positioning hole of the shell to be assembled 4, which can prevent the product from being scratched, and ensure accurate positioning and stability of the workpiece during processing or operation.

[0027] Preferably, the elastic positioning subassembly 11 further includes a reset driver 113, the driving end of the reset driver 113 is connected with at least part of the positioning pin 112, for driving the positioning pin 112 to reset and disengage from the shell supporting module 1 after the shell assembly is completed. Since the positioning effect of the positioning pin 112 on the shell to be assembled 4 needs to be cancelled after the shell assembly is completed, the positioning pin 112 is driven by the reset driver 113 to disengage from the shell supporting module 1, which facilitates the removal of the completed shell assembly and improves the processing efficiency of the product assembly. Wherein, the reset driver 113 is for example a pneumatic cylinder, an oil cylinder, a linear motor, etc.

[0028] Preferably, in combination with Figure 4 and Figure 5 As shown, the two side push correction clamping assemblies 12 move synchronously to drive the shell to be assembled 4 to perform position deviation correction with the elastic positioning subassembly 11 as the rotation support point, so that the shell to be assembled 4 is placed symmetrically with the center line of the two side push correction clamping assemblies 12 as the axis, so that the center axis of the shell coincides with the machining center, ensuring that the small part to be assembled 5 can be positioned and matched based on the center line when matched and assembled with the shell to be assembled 4, improving the assembly stability and accuracy, and reducing the assembly position tolerance.

[0029] Preferably, the side push correction clamping assembly 12 comprises at least one side push correction clamping block 122 moving linearly in the first axis X direction perpendicular to the center line, and the side push correction clamping blocks 122 on the same side are distributed outside the side push part 121 moving linearly in the center line direction relative to the shell support module 1, and the side push part 121 and each side push correction clamping block 122 are movably connected through a bevel gear transmission structure 123. The bevel gear transmission structure 123 converts the linear motion of the side push part 121 in the center line direction into the linear motion of the side push correction clamping block 122 perpendicular to the center line direction, so that the two sides of the shell 4 to be assembled are clamped or loosened by the side push correction clamping blocks 122 driven by the side push part 121, and the deviation correction is realized.

[0030] Preferably, the elastic positioning and centering assembly 11 is distributed at one end of the center line, and the side push parts 121 on both sides form a U-shaped structure through connecting rods 124, and the connecting rods 124 are located at the other end of the center line away from the elastic positioning and centering assembly 11, and the connecting rods 124 are connected with a side push driver 125. The side push driver 125 is, for example, a pneumatic cylinder, an oil cylinder, a linear motor, etc. The two side push parts 121 form an integrated U-shaped structure through the connecting rods 124, and then the side push driver 125 drives the connecting rods 124 to move to drive the two side push parts 121 to move synchronously, avoiding the deviation or damage of the workpiece caused by the asynchronous movement.

[0031] Preferably, the shell support module 1 is also provided with limiting blocks 126 distributed along the center line direction and triangularly distributed with the side push correction clamping blocks 122, and the limiting blocks 126 and the side push correction clamping blocks 122 are provided with buffer elastic members 127 distributed along the first axis X direction. The elastic buffer member is, for example, a spring. The limiting blocks 126 and the elastic buffer member limit the limit motion stroke of the side push correction clamping block 122, ensure the matching placement space of the shell 4 to be assembled, and avoid the excessive extrusion of the side push correction clamping block 122 to the shell 4 to be assembled, which causes the deformation of the shell. At the same time, the limiting blocks 126 and the elastic buffer member can avoid the scratch or scratch caused by the hard contact between the side push correction clamping block and the side wall of the shell 4 to be assembled. Further, the triangularly distributed limiting blocks 126 can form a stable triangular support structure, effectively resist deformation, and improve the carrying capacity of the overall structure.

[0032] Preferably, in combination with Figure 8 As shown, the heating and pressing module 3 comprises a pressing driver 31, a heating copper block 32, and a flexible buffer structure 33 located between the pressing driver 31 and the heating copper block 32. The flexible buffer structure 33 comprises, for example, a spring sleeve. The flexible buffer structure 33 is located between the pressing driver 31 and the heating copper block 32, which plays a buffering and damping role, protects the workpiece from excessive impact force, and ensures the stability of the pressing process.

[0033] Preferably, in combination withFigure 9 As shown, the small component assembly module 2 includes a small component support block 21 mounted on the housing support module 1, and a drive assembly that drives the small component support block 21 to move closer to the housing 4 to be assembled. The small component support block 21 is used to support the small component 5 to be assembled, for example, by magnetic attraction, clamping, or vacuum adsorption to fix the small component and prevent displacement during movement. The fixing of the small component is removed after assembly is completed. The drive assembly includes, for example, a translation driver 22 that drives the small component 5 to be assembled to move in a plane parallel to the housing support module 1, and a lifting driver 23 that drives the translation driver 22 and the small component 5 to be assembled together to move in a direction perpendicular to the plane of the housing support module 1. By adjusting the horizontal position and the lifting height, the small component 5 to be assembled can accurately reach the assembly position with the housing 4 to be assembled. The translation driver 22 and the lifting driver 23 are driven by, for example, servo motors or pneumatic / hydraulic drives.

[0034] Example 2

[0035] Combination Figure 10 As shown, the shell assembly production line provided in this embodiment includes a storage rack 20 to be assembled, an assembled storage rack 30, and a mechanical transfer device 40. The shell assembly production line also includes shell assembly equipment. The mechanical transfer device 40 is used to obtain the shell 4 to be assembled from the storage rack 20 and transfer it to the shell assembly equipment. The mechanical transfer device 40 is also used to obtain the assembled parts after being assembled by the shell assembly equipment and transfer them to the assembled storage rack 30.

[0036] It is understood that the shell assembly production line in this embodiment has the same beneficial effects as the shell assembly equipment in Embodiment 1, while reducing manual intervention, labor intensity and human error; secondly, through the continuous operation of the automated production line, production efficiency and capacity are improved.

[0037] Example 3

[0038] The shell assembly method provided in this embodiment, using shell assembly equipment, includes the following steps: S1. A conformal curing adhesive layer is pre-set on the assembly surface of the small parts and / or the housing 4 to be assembled; and the small parts are placed in the small parts assembly module 2 and the housing 4 to be assembled is placed in the housing support module 1 at the receiving position 101, and the elastic positioning centering component 11 is in concave-convex fit with the housing 4 to be assembled. S2, causing the S1 housing support module 1 to move to the pressing position 102, and the side push correction clamping components 12 distributed on opposite sides of the housing 4 to be assembled, using the elastic positioning centering component 11 as the rotation fulcrum, to correct and clamp the position of the housing 4 to be assembled. S3, the shell support module 1 of S2 uses negative pressure to adsorb and fix the shell 4 to be assembled, the small part assembly module 2 lifts the small part upward to touch the inner wall of the shell 4 to be assembled, and the heating and pressing module 3 contacts and heats the shell 4 to be assembled. The heating causes the conformal curing adhesive layer to be decured and to bond the small part and the shell 4 to be assembled. After the adhesive is cured, the small part is fixed to the inner wall of the shell 4 to be assembled. S4. The side-push correction clamping component 12 cancels the clamping, the elastic positioning centering component 11 cancels the concave-convex fit with the shell 4 to be assembled, and the shell support module 1 cancels the negative pressure adsorption, thus obtaining an assembly with small parts fixed on the inner wall.

[0039] Specifically, when the small part is placed in the small part assembly module 2 and the housing 4 to be assembled is placed in the housing support module 1 at the receiving position 101 in S1, the stored information such as the number of the small part 5 to be assembled and the housing 4 to be assembled can be identified by scanning a QR code to ensure that the model of the assembled workpiece is correct. At the same time, the photoelectric sensor can identify whether the housing 4 to be assembled is placed in place, and the photoelectric sensor recognizes the signal to determine whether to drive the elastic positioning centering component 11 to perform concave-convex engagement with the housing 4 to be assembled.

[0040] Specifically, in S3, when the small part is fixed to the inner wall of the housing 4 to be assembled after the adhesive is cured, the curing time of the adhesive is, for example, 55 to 65 seconds. The specific curing time can be adjusted according to the actual situation, and this embodiment does not limit it.
