[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0037] See Figure 1 and Figure 2 The illustrated electronic device 1 includes a circuit board 11 (PCBA) and a housing 12, wherein the circuit board 11 is mounted inside the housing 12, which is a plastic structure. During assembly, the circuit board 11 is vertically inserted into the housing 12. In the illustration, both the housing 12 and the circuit board 11 have a circular cross-section. However, the cross-sections of the housing 12 and the circuit board 11 can also be other structures, such as regular shapes like rectangles or circles, or even irregular shapes. This application only describes a structure with a circular cross-section.

[0038] To reduce collision issues during assembly, such as Figure 3 As shown, this application provides an assembly fixture 2 for assembling a circuit board 11 into a housing 12. The assembly fixture 2 includes a motion mechanism 22, a suction plate mechanism 23, and a carrier mechanism 24. The suction plate mechanism 23 is located at the moving end of the motion mechanism 22. The motion mechanism 22 drives the suction plate mechanism 23 to move along a first direction between the assembly position and the assembly position. The suction plate mechanism 23 includes a suction nozzle 234 for adsorbing the circuit board 11. The suction nozzle 234 can move in a second direction, which is perpendicular to the first direction. The assembly position supports the circuit board 11, and the assembly position supports the housing 12. The carrier includes a first mold 241 and a second mold 242, which clamp the housing 12 circumferentially. The first mold 241 and the second mold 242 are spliced ​​together in a third direction to form an assembly position, which is perpendicular to the second direction.

[0039] In the assembly process of this application, the first mold 241 and the second mold 242 clamp the housing 12 axially; the motion mechanism 22 drives the suction plate mechanism 23 to move to the assembly position in the first direction, the suction nozzle 234 moves along the second direction and suctions the circuit board 11, the suction plate mechanism 23 moves above the assembly position in the first direction, the suction nozzle 234 moves along the second direction and installs the circuit board 11 into the housing 12 in the second direction, thereby completing the assembly of the circuit board 11 and the housing 12 of the electronic device 1. In the above assembly process, the first mold 241 and the second mold 242 support the housing 12 from the third direction, which can straighten the housing 12, thereby solving the problem of collision between the circuit board 11 and the housing 12 due to the deformation of the housing 12 during the assembly process.

[0040] It should be noted that the second direction mentioned above corresponds to the vertical direction, the first direction corresponds to the left and right direction shown in the figure, and the third direction corresponds to the front and back direction shown in the figure. Of course, the first and second directions can also overlap, but this will not be described in detail here.

[0041] The function of the motion mechanism 22 is to drive the suction plate mechanism 23 to move in the first direction. Any mechanism that can enable the suction plate mechanism 23 to move in the first direction can be understood as the motion mechanism 22, such as a piston cylinder, a ball screw 223, etc.

[0042] See Figure 4 and Figure 5 The diagram illustrates the specific structure of the motion mechanism 22, which includes a support base 221, a servo motor 222, a ball screw 223, and a connecting block 224. The servo motor 222 and the ball screw 223 are mounted on the support base 221. The screw of the ball screw 223 is connected to the servo motor 222 for transmission and is arranged along a first direction. The connecting block 224 is connected to the nut of the ball screw 223 and moves with the nut in the first direction.

[0043] The servo motor 222 drives the ball screw 223 to move, thereby realizing the linear motion of the nut of the ball screw 223 in the first direction. The linear motion of the nut forms the linear motion of the connecting block 224.

[0044] The two ends of the ball screw 223 are connected to the support base 221 through two connecting plates. The two connecting plates are arranged opposite to each other. One end of the ball screw 223 is connected to one connecting plate, and the other end of the ball screw 223 is connected to the other connecting plate.

[0045] In the diagram, guide plates can also be arranged between the two connecting plates. Specifically, there are four guide plates, each connecting the opposite sides of the two connecting plates, and there is a guide gap between adjacent guide plates.

[0046] The connecting block 224 has a C-shaped structure and has two opposing guide parts. One guide part extends out of a guide gap to connect with the suction plate mechanism 23, and the other guide part extends out of another guide gap to connect with the suction plate mechanism 23. The two guide gaps are arranged adjacent to each other.

[0047] The function of the suction plate mechanism 23 is to drive the suction nozzle 234 to move in the second direction, so as to drive the circuit board 11 to move in the second direction through the suction nozzle 234. It can be a piston cylinder, a lead screw and nut mechanism, etc.

[0048] See Figure 6 The diagram illustrates the specific structure of the suction plate mechanism 23, which includes a first cylinder 231, a moving arm 232, a suction cup 233, and a suction nozzle 234. The cylinder body of the first cylinder 231 is fixed to the moving end of the motion mechanism 22. The piston rod of the first cylinder 231 is connected to the moving arm 232 and can slide relative to the cylinder body in a second direction. The suction cup 233 is mounted on the moving arm 232. The suction nozzle 234 is fixed to the suction cup 233.

[0049] After the rodless chamber of the first cylinder 231 is inflated, the piston rod extends relative to the cylinder body to push the moving arm 232 to move the suction nozzle 234 toward the assembly position or the position to be assembled; after the rod chamber of the first cylinder 231 is inflated, the piston rod retracts relative to the cylinder body to push the moving arm 232 to move the suction nozzle 234 away from the assembly position or the position to be assembled.

[0050] The illustration shows three suction nozzles 234. In other examples of this application, the number of suction nozzles 234 may be other numbers. To improve the applicability of the suction cup 233 mechanism, the suction nozzles 234 are detachably arranged on the suction cup 233. Specifically, the suction cup 233 is provided with mounting holes for mounting the suction nozzles 234, and the suction nozzles 234 are fixed to the suction cup 233 by nuts. In addition, the extension length of the suction nozzles 234 relative to the suction cup 233 is adjustable. By adjusting the position of the nut from the outer periphery of the suction nozzles 234, the extension length of the suction nozzles 234 relative to the suction cup 233 can be adjusted.

[0051] The aforementioned suction nozzle 234 achieves vacuum operation at the suction nozzle through an external air extraction mechanism. When the air extraction mechanism is activated, the suction nozzle 234 is in a vacuum state to adsorb the circuit board 11. When the air extraction mechanism is not activated or blows air, the suction nozzle 234 is in a normal pressure or positive pressure state to put down the circuit board 11.

[0052] The suction plate mechanism 23 also includes a limiting rod 235, which is set on the suction cup 233. By setting the limiting rod 235, the suction plate mechanism 23 can be restricted from moving to the extreme position to prevent the occurrence of collision with the circuit board 11.

[0053] The carrier mechanism 24 supports the housing 12 to correct any deformation of the housing 12. See also Figures 7 to 9 The carrier mechanism 24 shown in the figure includes a first mold 241, a second mold 242, a support block 244, and a second cylinder 245. The first mold 241 includes a first mold 2411, and the second mold 242 includes a second mold 2421. The first mold 2411 and the second mold 2421 are spliced ​​together to form an assembly position. The support block 244 includes a support step 2441 to form an assembly position. The cylinder body of the second cylinder 245 is fixed, and the piston rod of the second cylinder 245 is connected to the first mold 241 and drives the first mold 241 to move in a third direction.

[0054] In the aforementioned vehicle mechanism 24, the first mold 241 moves in a third direction relative to the second mold 242. In some other examples of this application, the second mold 242 may also move in a third direction relative to the first mold 241.

[0055] After the rodless chamber of the second cylinder 245 is filled with air, the piston rod extends relative to the cylinder body to push the second mold 242 to move closer to the first mold 241; after the rod chamber of the second cylinder 245 is filled with air, the piston rod retracts relative to the cylinder body to push the second mold 242 to move away from the first mold 241.

[0056] In this application, the inner wall 12a of the housing 12 is provided with a limiting part 121, and the circuit board 11 is provided with a notch 111 at the corresponding position of the limiting part 121. In order to ensure the alignment of the limiting part 121 and the notch 111, the first mold 2411 and the second mold 2421 are provided with protrusions 2412 of the housing 12. The protrusions 2412 are used to cooperate with the positioning part 122 on the outer wall 12b of the housing 12. When the protrusions 2412 cooperate with the corresponding positioning part 122, the limiting part 121 of the housing 12 is aligned with the notch 111 of the circuit board 11.

[0057] The aforementioned support block 244 is used to support the circuit board 11 to be assembled. In addition to supporting the step 2441, the support block 244 may also include a clearance groove 2442 to clear the electronic components on the circuit board 11.

[0058] To improve the applicability of the vehicle, the vehicle mechanism 24 may further include a support platform 243, a moving platform 246, a slide rail 247, a slider 248, and a third cylinder 249. The cylinder bodies of the support platform 243 and the second cylinder 245 are fixed on the platform of the moving platform 246. The first mold 241 and the second mold 242 are set on the support platform 243. The slider 248 is fixed on the moving platform 246 and slides in cooperation with the slide rail 247. The cylinder body of the third cylinder 249 is fixed, and the piston rod of the third cylinder 249 is connected to the moving platform 246 to drive the moving platform 246 to move in a third direction.

[0059] After the rodless chamber of the third cylinder 249 is filled with air, the piston rod extends relative to the cylinder body to push the moving stage 246 toward the suction plate mechanism 23; after the rod chamber of the third cylinder 249 is filled with air, the piston rod retracts relative to the cylinder body to push the moving stage 246 away from the suction plate mechanism 23.

[0060] By setting the carrier mechanism 24 to move in a third direction, the positions of the carrier mechanism 24 and the suction plate mechanism 23 in the third direction can be adjusted for different specifications of electronic devices 1, thereby improving the applicability of the device.

[0061] It should be noted that the aforementioned carrier mechanism 24 may also omit the support platform 243 and directly place the first mold 241 and the second mold 242 on the moving platform 246. Compared with the carrier mechanism 24 without the support platform 243, this can reduce the processing accuracy of the moving platform 246.

[0062] Furthermore, this application Figure 3 The assembly tooling 2 disclosed in the paper includes a carrier mechanism 24. Figure 10 Two vehicle mechanisms 24 were disclosed, and of course, there could be more than one vehicle mechanism 24.

[0063] When there are at least two vehicle mechanisms 24, each of the at least two vehicle mechanisms 24 may correspond to one suction plate mechanism 23, or may correspond to at least two vehicle mechanisms 24, which will not be described in detail here.

[0064] The structure used to support the motion mechanism 22 and the carrier mechanism 24 in this application can be any surface structure. For the integrated setup of this assembly fixture 2, see [link to relevant documentation]. Figure 3 and Figure 10 The assembly fixture 2 also includes a workbench 21, and the motion mechanism 22 and the carrier mechanism 24 are both arranged on the workbench 21.

[0065] Additionally, see Figure 11 In order to protect the motion mechanism 22, the suction plate mechanism 23 and the carrier mechanism 24, the assembly fixture 2 also includes a protective cover 25, which covers the motion mechanism 22, the suction plate mechanism 23 and the carrier mechanism 24 and is fixed on the worktable 21.
