The control circuit board generally uses an FPC flexible flat cable, which is convenient for attaching it to the fan cover plate to fix the cable. Because the structure of the flexible flat cable itself is relatively complex, and one end of it is located inside the fan while the other end needs to pass through the fan cover plate and extend out of the fan, therefore, in the process of automatic assembly, how to achieve the perforation of the FPC flexible flat cable has become an urgent problem to be solved. Content of the Utility Model

[0045] The above-mentioned fixture assembly further includes: a substrate 12 with one end connected to the above-mentioned first rotating disk 25 and a carrier plate 13 mounted on the other end of the substrate 12 for loading the fan cover 200. When the first rotating disk 25 rotates to the first position, the upper surface of the horizontally placed carrier plate 13 contacts the lower surface of the fan cover 200. When the first rotating disk 25 rotates to the second position, the fan cover 200 mounted on the carrier plate 13 rotates to the vertical state with the carrier plate 13, and the through hole 201 on the fan cover 200 is located above the carrier plate 13.

[0046] The above-mentioned connecting section 103 is an arc connecting section.

[0047] The above-mentioned base 1 is slidably mounted on a horizontally arranged bottom substrate 3 and can move in the horizontal direction.

[0048] A transverse cylinder 18 is mounted on the upper surface of the above-mentioned bottom substrate 3. The piston rod of this transverse cylinder 18 is connected to the base 1 through a first connecting block 51.

[0049] The base 1 is an L-shaped base, and the lower surface of the horizontal portion of the base 1 and the upper surface of the bottom substrate 3 are connected by at least one set of slide rails and sliders.

[0050] The support plate 2 is slidably mounted on the vertical portion of the base 1 and is movable in the vertical direction.

[0051] The support plate 2 is connected to one side surface of the vertical portion of the base 1 through at least one set of slide rails and slide blocks. A vertical cylinder 18 is installed on the other side surface of the vertical portion of the base 1. The piston rod of the vertical cylinder 18 is connected to the support plate 2 through a second connecting block 52.

[0052] When in use, the fan cover is loaded onto the fixture assembly for positioning, the flexible flat cable is placed on the carrier block and the support block for positioning, the position of the fan cover is adjusted by the X-axis drive unit and the Z-axis drive unit, and the position of the flexible flat cable is adjusted by the Y-axis drive unit, so that the fan cover in a vertical state and the flexible flat cable in a horizontal state are close to each other, and one end of the arc section of the flexible flat cable is aligned with the through hole of the fan cover;

[0053] Then, the fan cover plate loaded on the clamp assembly is driven to move by the X-axis driving unit, so that one end of the arc segment of the flexible flat cable passes through the through hole on the fan cover plate. After one end of the arc segment passes through the through hole, the cylinder drives the clamping claw cylinder to move, so that the two clamping parts of the clamping claw cylinder clamp one end of the arc segment passing through the through hole. At this time, the cylinder drives the support block away from the lower surface of the arc segment of the flexible flat cable. Then, the second rotating disk is driven by the second rotating driving unit to drive the base, the vertical support frame and the cylinder installed on the second rotating disk to rotate synchronously in forward and reverse directions and cooperate with the horizontal contraction of the cylinder and the horizontal movement of the base to pass the arc segment and the receiving section of the flexible flat cable through the through hole on the fan cover plate.

[0054] When the fan cover needs to be clamped, the rotating disk is rotated to the first position, so that the carrier plate rotating with the rotating disk rotates to a horizontal state. At this time, the fan cover to be clamped is placed on the carrier plate so that its lower surface is in contact with the upper surface of the carrier plate. The positioning protrusion on the carrier plate and the mounting through hole on the fan cover plate cooperate with each other to achieve positioning of the fan cover. Then, the vacuum generator is turned on to achieve uniform adsorption and positioning of the entire surface of the fan cover through the adsorption groove.

[0055] After the fan cover is clamped, the rotating disk is rotated to the second position, so that the carrier plate rotating with the rotating disk rotates to a vertical state, and the fan cover plate stably clamped on the carrier plate also rotates to a vertical state, which is convenient for subsequent processing operations on the fan cover plate;

[0056] During the processing of the flexible flat cable, first place the piston rod of the cylinder in the extended state, then pick up and place the flexible flat cable on the carrier block and the support block manually or by a robotic arm, and make the straight section of the flexible flat cable located on the upper surface of the rib portion of the carrier block, and the arc section of the flexible flat cable located in the groove of the support block. The position of the flexible flat cable can be further calibrated manually or by visual positioning to make one side surface thereof fit with the side wall of the groove on the support block and the side wall of the support block.

[0057] Then turn on the vacuum generator connected to the cavity in the carrier block, and position the straight section of the flexible flat cable through vacuum adsorption to avoid the position deviation of the entire flexible flat cable and ensure the position accuracy of the flexible flat cable during the subsequent processing.

[0058] When further processing of the arc section of the flexible flat cable is required, place the piston rod of the cylinder in the retracted state, and the support block moves backward and downward with the piston rod of the cylinder to withdraw from the arc section of the flexible flat cable, avoiding the interference of the support block during the processing of the arc section of the flexible flat cable and facilitating the processing operation.

[0059] Adopting the perforating mechanism for the flexible flat cable of the present utility model, it can not only stably clamp the flexible flat cable and the fan cover plate respectively, but also flip the clamped fan cover plate to facilitate passing the flexible flat cable through the fan cover plate. It can also pass a part of the flexible flat cable through the fan cover plate while ensuring the position accuracy and stability of the flexible flat cable, improving the automation degree of assembling the fan and the position accuracy and stability of each component during the assembling process.

[0060] The above embodiments are only used to illustrate the technical concept and features of the present utility model, and their purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly. It should not be used to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit of the present utility model should be covered within the protection scope of the present utility model.
