DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1 As shown, the soft needle pressing assembly device of the utility model comprises several main parts: a linear motor 1, a moving carrier 2, a soft needle manipulator 3, a carrier unlocking component 4 and a soft needle pressing component 5; the moving carrier 2 is connected to the mover of the linear motor 1, and the moving carrier 2 is provided with a bottom shell to be assembled, and the linear motor 1 is used to drive the moving carrier 2 to move linearly to the assembly position; the soft needle manipulator 3 is used to grab the soft needle, and the soft needle manipulator 3 is used to insert the soft needle into the bottom shell installation position; the carrier unlocking component 4 is used to unlock the bottom shell installation position of the moving carrier 2 so that the bottom shell can be placed in it; the soft needle pressing component 5 is used when the soft needle manipulator 3 clamps the soft needle to assemble it on the bottom shell of the moving carrier 2, and the soft needle pressing component 5 presses down the soft needle for assembling the soft needle to the bottom shell installation position.

[0030] Reference Figure 2 , 3 As shown, the soft needle pressing assembly 5 includes a column 51, a lifting cylinder 52, an adapter plate 53, a push-out cylinder 54, a pressure head mounting plate 55 and a soft needle limiting pressure head 56.

The lifting cylinder 52 drives the soft needle limiting pressure head 56 to move up and down in the vertical direction, so that the soft needle limiting pressure head 56 presses the soft needle from above, and the push-out cylinder 54 drives the soft needle limiting pressure head 56 to move linearly in the horizontal direction, so that the soft needle limiting pressure head 56 is close to the soft needle.

[0031] In order to ensure the assembly yield of the soft needle and the bottom shell, a visual guidance CCD camera 57 and a light source 58 are provided on the column 51. The visual guidance CCD camera 57 is located directly above the installation position of the mobile carrier 2, and the light source 58 is used to provide light for the visual guidance CCD camera 57. After the soft needle pressing assembly 5 presses the soft needle to the installation position of the bottom shell, the visual guidance CCD camera 57 takes pictures again to re-inspect the assembly effect of the soft needle and the bottom shell. If the re-inspection result is qualified, the linear motor 1 transports the mobile carrier 2 to the next station; if the re-inspection result is unqualified, the carrier unlocking assembly 4 is pushed out to unlock the mobile carrier 2. After the soft needle manipulator 3 takes away the unqualified materials, the carrier unlocking assembly 4 is reset, and the linear motor 1 transports the mobile carrier 2 to the next station.

[0032] The soft needle pressing assembly device of the utility model further includes a mounting base 6, on which a linear guide rail 61 is provided, and the linear guide rail 61 is provided along the moving direction of the mover of the linear motor 1. A linear slider 20 is connected to the moving carrier 2, and the linear slider 20 slides along the linear guide rail 61.

[0033] Reference Figure 4 As shown, the soft needle manipulator 3 includes a mechanical arm 31, a clamping cylinder mounting plate 32 and a clamping cylinder 33. The clamping cylinder mounting plate 32 is connected to the mechanical arm 31, and the clamping cylinder 33 is mounted on the clamping cylinder mounting plate 32. The clamping claw of the clamping cylinder 33 is used to clamp the soft needle. The clamping claw cylinder 33 used in this embodiment clamps the soft needle. Different clamping structures can be selected for different parts to be assembled, such as a suction nozzle.

[0034] Reference Figure 5-7 As shown, the mobile carrier 2 includes a base 21, a rectangular supporting plate 22, a bearing plate 23 and a locking assembly 24. The base 21 is connected to the mover of the linear motor 1, the rectangular supporting plate 22 and the base 21 are fixedly connected, the bearing plate 23 and the locking assembly 24 are arranged on the rectangular supporting plate 22, and a bottom shell is provided on the bearing plate 23. The locking assembly 24 is used to press the bottom shell onto the bearing plate 23.

[0035] Reference Figure 8 As shown, a bottom shell placement groove 231 is provided on the upper end surface of the supporting plate 23, and the side of the bottom shell placement groove 231 close to the locking assembly 24 is set as an opening structure. The bottom shell is placed in the bottom shell placement groove 231, and the locking assembly 24 passes through the opening to press the bottom shell in the bottom shell placement groove 231, so that the bottom shell is positioned in the bottom shell placement groove 231.

[0036] In the above structure, the locking assembly 24 includes a locking block 241, a moving block 242, a return spring 243 and a stop block 244, the stop block 244 is installed on the rectangular supporting plate 22, the locking block 241 is installed on the moving block 242, the moving block 242 slides along the stop block 244, the return spring 243 is arranged between the moving block 242 and the stop block 244 to provide a return force for the moving block 242, and the locking block 241 is used to lock the bottom shell on the supporting plate 23.

[0037] In addition, the vehicle unlocking assembly 4 includes an unlocking support seat 41, an unlocking push cylinder 42 and an unlocking push plate 43. The unlocking push cylinder 42 is fixedly mounted on the unlocking support seat 41, and the unlocking push plate 43 is connected to the piston rod of the unlocking push cylinder 42. The unlocking push cylinder 42 drives the unlocking push plate 43 to contact the moving block 242.

[0038] Reference Fig. 9 As shown, the unlocking push plate 43 is a rectangular flat plate, a convex portion 245 is provided on the moving block 242 , the unlocking push plate 43 is arranged opposite to the convex portion 245 , and the unlocking push plate 43 and the convex portion 245 are in contact.

[0039] The working principle of the locking assembly 24 and the vehicle unlocking assembly 4 is as follows:

[0040] The piston rod of the unlocking and pushing cylinder 42 extends out, and pushes the unlocking push plate 43 to contact the moving block 242, thereby driving the moving block 242 to move, so that the locking block 241 changes from the state of pressing the bottom shell in the bottom shell placement groove 231 to the released state. At this time, the return spring 243 is compressed and can drive the bottom shell in the bottom shell placement groove 231; when the bottom shell to be assembled is placed in the bottom shell placement groove 231, when the piston rod of the unlocking and pushing cylinder 42 is retracted, the unlocking push plate 43 is separated from the moving block 242, and the moving block 242 moves toward the inside of the bottom shell placement groove 231 under the action of the elastic restoring force of the return spring 243, and the locking block 241 pushes the bottom shell to be assembled to abut against the inner wall of the bottom shell placement groove 231, thereby completing the pressing and positioning of the bottom shell to be assembled.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
