The fixture translation drive mechanism 52 is drivenly connected to the fixture mounting plate 51. A wiper positioning fixture 53 is mounted on the upper surface of the fixture mounting plate 51, and a welding mounting seat 54 is mounted on the lower surface of the fixture mounting plate 51. The ultrasonic welding assembly 2 is mounted on the welding mounting seat 54.

[0027] Furthermore, such as Figure 7As shown, the wiper unloading assembly 4 includes an unloading mounting frame 41 mounted on the frame 1. The upper end of the unloading mounting frame 41 is equipped with an unloading translation drive cylinder 42 that moves horizontally back and forth. The drive end of the unloading translation drive cylinder 42 is equipped with an unloading translation movable frame 43. The unloading translation movable frame 43 is equipped with an unloading lifting drive cylinder 44 that moves vertically. The drive end of the unloading lifting drive cylinder 44 is equipped with an unloading lifting movable frame 45. A welding clamping block 46 is installed in the middle of the unloading lifting movable frame 45. Unloading pneumatic grippers 47 are installed at the left and right ends of the unloading lifting movable frame 45, respectively.

[0028] Furthermore, such as Figure 4 As shown, a laser marking machine 6 is mounted on the rear end of the fixture mounting plate 51 of the frame 1.

[0029] It should be noted that the ultrasonic welding and coding equipment for windshield wipers in this embodiment is equipped with a PLC controller. The ultrasonic welding assembly 2, the windshield wiper loading assembly 3, the unloading translation drive cylinder 42, the unloading lifting drive cylinder 44, the unloading pneumatic gripper 47, and the fixture translation drive mechanism 52 are all electrically connected to the PLC controller. During operation, the PLC controller controls the operation of the ultrasonic welding assembly 2, the windshield wiper loading assembly 3, the unloading translation drive cylinder 42, the unloading lifting drive cylinder 44, the unloading pneumatic gripper 47, and the fixture translation drive mechanism 52.

[0030] For the fixture translation drive assembly 5 in this embodiment, the fixture translation drive mechanism 52 drives the fixture mounting plate 51 to move horizontally back and forth, and the wiper positioning fixture 53 moves horizontally synchronously with the fixture mounting plate 51; wherein, when the fixture translation drive mechanism 52 drives the fixture mounting plate 51 to move forward to the limit position, the wiper positioning fixture 53 moves forward to the welding operation position; when the fixture translation drive mechanism 52 drives the fixture mounting plate 51 to move backward to the limit position, the wiper positioning fixture 53 moves backward to the inkjet printing operation position.

[0031] The following is a detailed description of the ultrasonic welding and coding equipment for windshield wipers in Embodiment 1, using specific working processes as an example: Step a: The jig translation drive mechanism 52 drives the jig mounting plate 51 and the wiper positioning jig 53 to move backward, and the wiper positioning jig 53 moves backward to the coding operation position. Step b: After the wiper positioning fixture 53 moves to the coding operation position, the wiper feeding component 3 is activated and grabs and transfers the wiper semi-finished product to the wiper positioning fixture 53, and the wiper positioning fixture 53 positions the wiper semi-finished product. Step c: After the wiper feeding assembly 3 transfers the wiper semi-finished product to the wiper positioning fixture 53, the laser marking machine is activated. During this process, the laser marking machine performs marking operations on the snap ring surface of the wiper semi-finished product. Step d: After the laser marking machine completes the marking operation, the fixture translation drive mechanism 52 drives the fixture mounting plate 51 and the wiper positioning fixture 53 to move forward, and moves the wiper positioning fixture 53, which is loaded with the wiper semi-finished product, to the welding operation position. Step c: After the wiper positioning fixture 53 moves forward to the welding operation position, the unloading translation drive cylinder 42 drives the unloading translation movable frame 43, the unloading lifting drive cylinder 44, the unloading lifting movable frame 45, the welding clamping block 46, and the unloading pneumatic gripper 47 to move backward, so that the welding clamping block 46 moves backward to directly above the wiper positioning fixture 53. Then, the unloading lifting drive cylinder 44 drives the welding clamping block 46 and the unloading pneumatic gripper 47 to move downward, so that the welding clamping block 46 presses down on the wiper positioning fixture 53 to clamp the wiper semi-finished product. Step d: After the clamping block 46 clamps and fixes the wiper semi-finished product, the ultrasonic welding component 2 is activated and completes the ultrasonic welding process of the wiper semi-finished product that has been inkjet printed, so as to obtain the wiper finished product. Step e: After the ultrasonic welding assembly 2 completes the ultrasonic welding operation, each of the unloading pneumatic grippers 47 moves and grabs the finished wiper. Then, the unloading lifting drive cylinder 44 drives the unloading lifting movable frame 45 to move upward. The finished wiper grabbed by the unloading pneumatic grippers 47 is removed from the wiper positioning fixture 53. Finally, the unloading translation drive cylinder 42 drives the unloading translation movable frame 43 to move forward to realize the unloading of the finished wiper.

[0032] It should be emphasized that the ultrasonic welding and marking equipment for windshield wipers in this embodiment can achieve both automatic marking of semi-finished windshield wiper parts and automatic ultrasonic welding of semi-finished windshield wiper parts. Furthermore, the finished windshield wiper parts can be obtained after marking and ultrasonic welding. Compared to existing technologies, the ultrasonic welding and marking equipment for windshield wipers in this embodiment has the advantages of novel structural design and diverse functions.

[0038] It should be noted that the lifting drive component 21 is a lifting drive cylinder or a lifting servo module.

[0039] When the wiper semi-finished product moves forward to the welding operation position along with the fixture mounting plate 51 and the wiper positioning fixture 53, after the welding clamping block 46 clamps and fixes the wiper semi-finished product, the lifting drive component 21 drives the ultrasonic welding head 22 to move upward. The upward-moving ultrasonic welding head 22 passes through the clearance hole 55 and contacts the wiper semi-finished product. Then, the ultrasonic welding head 22 is pneumatically operated and completes the ultrasonic welding process of the wiper semi-finished product to obtain the finished wiper product.

[0041] In the process of loading the wiper loading assembly 3 in this embodiment 4, the loading translation drive linear module 32 first drives the loading pneumatic gripper 37 to move above the wiper semi-finished product gripping position, and then the loading lifting drive cylinder 34 drives the loading pneumatic gripper 37 to move down and make the loading pneumatic gripper 37 grip the wiper semi-finished product; after the loading pneumatic gripper 37 grips the wiper semi-finished product, the loading translation drive linear module 32 drives the gripped wiper semi-finished product to be transferred to the wiper positioning fixture 53 located at the inkjet printing operation position, and then the loading lifting drive cylinder 34 drives the loading pneumatic gripper 37 and the wiper semi-finished product to move down, so as to place the wiper semi-finished product on the wiper positioning fixture 53.

[0042] Example 5, such as Figure 4 As shown, the difference between this fifth embodiment and the first embodiment is that: the frame 1 is equipped with a finished product conveyor belt 7 at the front end of the unloading mounting frame 41, and an inclined finished product slide 8 is installed between the finished product conveyor belt 7 and the unloading mounting frame 41.

[0043] After the wiper unloading assembly 4 feeds out the finished wiper, it places the finished wiper on the finished product slide 8. The finished wiper slides down the finished product slide 8 onto the finished product conveyor belt 7, which then feeds out the finished wiper.
