Technical Field
[0001] This utility model relates to the field of gate removal technology for reflectors, and in particular to a device for removing gates from freeform surface reflectors used in automotive head-up displays. Background Technology
[0002] HUD (Head-Up Display) plastic freeform surface mirrors have become increasingly widely used in new energy vehicles in recent years, serving as a crucial component of HUD technology. This technology utilizes optical projection to project important information from the car's dashboard (such as speed and navigation) onto the windshield in front of the driver, reducing driving risks caused by drivers looking down at the dashboard. Currently, HUD plastic freeform surface mirrors are manufactured using injection molding, resulting in gates at the point of production. The industry primarily uses CNC machining to remove these gates. However, CNC machining requires programming, is less efficient, and the expensive equipment adds a burden to manufacturers.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] Please see Figures 1 to 6 This utility model provides an embodiment:
[0023] Please see Figure 1 and Figure 3 A freeform surface reflector gate removal device for automotive head-up displays includes a square steel frame 1, a worktable 2 fixed on the top of the square steel frame 1, a positioning fixture 3 for fixing the reflector on the worktable 2, an X-axis slide module 4 for driving the positioning fixture 3 to move left and right on the worktable 2, and a cutting component for cutting the reflector gate on the worktable 2, which is driven by a Y-axis slide module 5.
[0024] Please see Figure 1 and Figure 4 The cutting assembly includes a circular saw blade 6, which is driven by a motor 7, which is mounted on the movable seat of the Y-axis slide module 5. During cutting, the motor 7 is moved to the position to be cut by the Y-axis slide module 5, and then the motor 7 starts, driving the circular saw blade 6 to rotate rapidly. When the gate of the reflector comes into contact with the rotating circular saw blade 6, the gate of the reflector can be cut and removed.
[0025] Please see Figure 1 and Figure 4 A dust cover 8 is provided on the circular saw blade 6, and a vacuum cleaner interface 9 is provided at the end of the dust cover 8. For example... Figure 4 As shown, the dust cover 8 is connected to the vacuum cleaner interface 9. When the vacuum cleaner pipe is connected to the vacuum cleaner interface 9, the vacuum cleaner will generate suction under the dust cover 8 when it is started, thereby drawing the cut-off reflector gate into the vacuum cleaner through the dust cover 8 and the vacuum cleaner interface 9.
[0026] Please see Figure 1 The bottom of the square steel frame 1 is also equipped with an adjustment component for adjusting the height of the square steel frame 1.
[0027] Please see Figure 1 , Figure 5 and Figure 6 The adjustment assembly includes a foot cup 10 located at the bottom of the square steel frame 1. The foot cup 10 is connected to the square steel frame 1 via a foot cup plate 11. A threaded hole is provided through the foot cup plate 11. A screw 12 that mates with the threaded hole is provided above the foot cup 10. A locking nut 13 for locking is provided on the screw 12.
[0028] Please see Figure 1 , Figure 5 and Figure 6A fixing nut 14 for assisting in rotating the foot cup 10 is fixed below the locking nut 13 on the foot cup 10. When it is necessary to adjust the height of the square steel frame 1, the fixing nut 14 of the foot cup 10 can be rotated by using a wrench. The screw 12 on the foot cup 10 is threaded into the threaded hole through the foot cup plate 11, thereby adjusting the height of the foot cup 10 and thus adjusting the height of the square steel frame 1.
[0029] Please see Figure 5 and Figure 6 Rollers 15 are installed at each of the four corners of the square steel frame 1.
[0030] Please see Figure 1 and Figure 5 A control handle 16 is provided on one side of the square steel frame 1.
[0031] Working principle: Place the HUD plastic freeform surface reflector onto the positioning fixture 3. Use the control handle 16 to program the machining process. When the start button is pressed, the positioning fixture 3 automatically activates negative pressure adsorption, adsorbing the reflector onto the fixture 3 to prevent loosening during machining. The Y-axis slide module drive 5 cutting component reaches the gate cutting position set in the program. Subsequently, the motor 7 is started, driving the circular saw blade 6 to rotate rapidly. Figure 2 As shown, the vacuum cleaner connected to the vacuum cleaner interface 9 at the end of the dust cover 8 and the vacuum cleaner interface 17 of the positioning fixture is started. The X-axis slide module 4 drives the positioning fixture 3 to move. The gate of the reflector adsorbed on the positioning fixture 3 comes into contact with the circular saw blade 6 during the movement, thereby cutting off the gate. The gate that falls off during the cutting process is sucked into the vacuum cleaner through the vacuum cleaner interface 9 and the vacuum cleaner interface 17 of the positioning fixture. After the cutting is completed, the cutting component stops cutting, and the vacuum cleaner is turned off. The Y-axis slide module 5 drives the cutting component to move to the starting point, and the X-axis slide module 4 drives the positioning fixture 3 to move to the starting point. The positioning fixture 3 closes the negative pressure suction, and the operator can then remove the gate-removed reflector and... The separated gate is removed, completing the removal of the reflector gate; since the four corners of the square steel frame 1 are equipped with rollers 15, when it is necessary to move the device, the square steel frame 1 can be directly pushed to a suitable position. Then, the fixing nut 14 of the foot cup 10 is rotated with a wrench. The screw 12 on the foot cup 10 is threaded into the threaded hole through the foot cup plate 11, so that the foot cup 10 is moved to the ground to fix the position of the square steel frame 1. Then, the locking nut 13 on the screw 12 is rotated to abut against the bottom surface of the foot cup plate 11, so that the height of the square steel frame 1 can be fixed. When it is necessary to adjust the height of the square steel frame 1, the fixing nut 14 on the foot cup 10 can also be used to adjust the height of the square steel frame 1 by rotating the wrench.
