[0025] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0027] See also Figure 1 and Figure 2 As shown, the utility model designs a protective film recovery device, which includes a supporting member, a grabbing member, a film connecting plate 30 and a film collecting bin 15. The supporting member supports a PCB. The grabbing member is used to grab the protective film on the PCB and place the protective film on the film connecting plate 30. The first end of the film connecting plate 30 is connected to a blowing member. The film collecting bin 15 is placed below the second end of the film connecting plate 30. When the blowing member is started, the protective film on the film connecting plate 30 falls into the film collecting bin 15.

[0028] It should be noted that the protective film recovery device of the utility model includes a supporting member, a grabbing member, a film receiving plate 30, a blowing member and a film receiving bin 15. The PCB is placed on the supporting plate, and the grabbing member grabs the protective film on the PCB. When the protective film is completely separated from the PCB, the grabbing member places the protective film on the film receiving plate 30. The first end of the film receiving plate 30 is connected to the blowing member, and the second end of the film receiving plate 30 is arranged opposite to the first end, and a film receiving bin 15 is provided below. When the blowing member is started, the protective film can be blown into the film receiving bin 15. Compared with the existing technology, it does not need to rely on manual labor, the efficiency is greatly improved, and the damage and pollution problems caused by manual operation are avoided.

[0029] Specifically, the protective film recovery device further includes a film collecting vehicle 16 . The film collecting bin 15 is provided with a discharge port, and the film collecting vehicle 16 is provided with a feed port. The discharge port of the film collecting bin 15 is connected to the feed port of the film collecting vehicle 16 .

[0030] Specifically, the protective film recovery device also includes a frame, and the film collection bin 15 includes side panels 14, a bottom plate 10 and a slide plate 13. The bottom plate 10 and the side panels 14 are both connected to the frame, and the slide plate 13 is slidably connected to the bottom plate 10 to push the protective film in the film collection bin 15 to the film collection vehicle 16.

[0031] Specifically, the protective film recovery device further includes a slider 12 and a slide rail 11 . The slide rail 11 is connected to the bottom plate 10 . The slider 12 is placed on the slide rail 11 and connected to the slide plate 13 .

[0032] Specifically, the protective film recovery device further includes a baffle 17 , which is connected to the side plate 14 and is used to prevent the slider 12 from being separated from the slide rail 11 .

[0033] Specifically, the protective film recovery device further includes a first driver, which is connected to the slider 12 or the slide plate 13 and is used to drive the slider 12 to slide along the slide rail 11 .

[0034] When the slide plate 13 moves to the discharge port of the film collecting bin 15, the protective film is pushed to the feed port of the film collecting bin 16, thereby realizing the transfer of the protective film from the film collecting bin 15 to the film collecting bin 16, without the need for manual intervention of the operator to reach into the film collecting bin 15 for film collecting, thus avoiding the occurrence of accidents. At this time, the first drive is started in the reverse direction, so that the first drive drives the slide plate 13 to move in the direction away from the film collecting bin 16, until the slide plate 13 abuts against the baffle plate 17, and the first drive is closed, and the film collecting bin 15 can continue to collect the film without stopping. Of course, it should be noted that the first drive of the present utility model can be a push rod, or a telescopic motor or other device, and the present utility model is not limited to this.

[0035] Specifically, the supporting member includes a second driver and a plurality of conveying rollers 32 . The second driver is connected to all the conveying rollers 32 and is used to drive the conveying rollers 32 to rotate so as to convey the PCB.

[0036] Specifically, the gripping member includes a clamp 23 and a linear module. The linear module connects the clamp 23 and the frame and is used to drive the clamp 23 to move to the feed end of the conveying roller 32 or to drive the clamp 23 to move to the film receiving plate 30. The clamp 23 is used to separate the protective film from the PCB and place it on the film receiving plate 30.

[0037] Specifically, the protective film recovery device further includes a sensor, which is disposed at the feed end of the conveying roller 32 and is electrically connected to the grabbing member.

[0038] Specifically, the blowing component includes an air pump and a plurality of blowing plates 31 . The plurality of blowing plates 31 are distributed at intervals on the film connection plate 30 , and the air pump is connected to the blowing plates 31 .

[0039] It should be noted that the linear module of the utility model includes an X-axis guide rail 20, a Y-axis guide rail 21 and a Z-axis guide rail 22. When the sensor senses that there is a PCB at the feed end of the conveying roller 32, the sensor can send a signal to the linear module, and the linear module drives the clamp 23 to the feed end of the conveying roller 32. The clamp 23 can grab the protective film of the PCB, and the conveying roller 32 drives the PCB to move in the horizontal direction, and the protective film gradually separates from the PCB. When the protective film is completely separated from the PCB, the linear module drives the clamp 23 to move to the film connection table. At this time, the air pump is started. When the air pump is started, it will convey airflow to the blowing plate 31. These airflows are evenly blown toward the protective film on the film connection plate 30 through the small holes on the blowing plate 31. The adhesion between the protective film and the film connection plate 30 is weakened, so that the protective film can easily fall off from the film connection plate 30.
