Technical field
The utility model relates to a kind of auxiliary fixture for CMOS image sensor (CIS:CMOS Image Sensor) is taken out from the support plate (CARRIER) of rubberizing film.
Background technology
In the production process of image sensor, need to stick glued membrane at image sensor, common way is, uses a support plate 1 that posts glued membrane, image sensor 11 is attached on the glued membrane of support plate, produces and image sensor taken out from glued membrane after finishing again.
Past mainly is to adopt manually product to be ejected from the glued membrane back side with tweezers first when image sensor is taken out from support plate, once ejects 1, again pallet is put in product gripping from the glued membrane, and a slice support plate is totally 32 products, namely will repeat operation 32 times.This manual working had both made the support plate distortion scrap easily, increased again operator operation intensity, and inefficiency.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes a kind of image sensor ejection fixture.
The technical solution adopted in the utility model is as follows:
The image sensor ejection fixture, comprise a hollow housing, the housing upper surface is provided with upper cover plate, is provided with the intermediate plate of placing the image sensor support plate below the inherent upper cover plate of housing, intermediate plate middle part hollow out is exposed the image sensor that posts glued membrane on the image sensor support plate; And be located at thimble fixed head below the intermediate plate, and the thimble fixed head is provided with thimble, and the thimble position is corresponding one by one with the position of image sensor that posts glued membrane on the image sensor support plate; Thimble fixed head bottom is provided with and drives the drive unit that the thimble fixed head rises or descends; Be provided with spring between thimble fixed head and the intermediate plate.
Preferably, described drive unit is pneumatic actuating device, comprises the cylinder that is located at thimble fixed head bottom, and the switch of control cylinder.
Preferably, described switch is the foot switch with auto-lock function.
Preferably, be provided with guide pillar in the housing, intermediate plate and thimble fixed head all are socketed on the guide pillar, rise or descend along guide pillar.Guide pillar can be controlled intermediate plate and thimble fixed head in the process that rises or descend, and the position is not offset.
Preferably, the intermediate plate upper surface is provided with spacing fixed head, reserves between intermediate plate and the spacing fixed head for the image sensor support plate and inserts the track of placing.The setting of spacing fixed head can make support plate fix, and is difficult for stress deformation when ejecting.
Preferably, the intermediate plate upper surface is provided with alignment pin, is used for regulating the height gap between control fixed head and the intermediate plate.
The beneficial effects of the utility model are, and are simple to operate, need not the professional skill training, replace manually to eject operation, the waste that the support plate distortion of avoiding handwork to cause is scrapped, and operating personnel only need step on foot switch can realize that product ejects, and reduces operation intensity; Manual operation once ejects 1 product, uses this tool once to eject 32 products, has improved production efficiency.

Embodiment
Below in conjunction with specific embodiments and the drawings, the technical solution of the utility model is described further.
Participate in Fig. 1 to Fig. 5, the image sensor ejection fixture, comprise a hollow housing 2, housing 2 upper surfaces are provided with upper cover plate 3, be provided with the intermediate plate 4 of placing image sensor support plate 1 below the housing 2 inherent upper cover plates 3, intermediate plate 4 middle part hollow outs are exposed the image sensor that posts glued membrane 11 on the image sensor support plate 1; And be located at thimble fixed head 5 below the intermediate plate 4, and thimble fixed head 5 is provided with thimble 51, and thimble 51 positions are corresponding one by one with the image sensor that posts glued membrane 11 positions on the image sensor support plate 1; Thimble fixed head 5 bottoms are provided with and drive the pneumatic actuating device that the thimble fixed head rises or descends, and it comprises the cylinder 61 that is located at thimble fixed head 5 bottoms, and the foot switch 62 with auto-lock function of control cylinder; Be provided with spring 7 between thimble fixed head 5 and the intermediate plate 4.
Be provided with guide pillar 8 in the housing 1, intermediate plate 4 and thimble fixed head 5 all are socketed on the guide pillar 8, can rise or descend along guide pillar 8.Guide pillar can be controlled intermediate plate and thimble fixed head in the process that rises or descend, and the position is not offset.
Intermediate plate 4 upper surfaces are provided with spacing fixed head 41 and alignment pin 42, reserve between intermediate plate 4 and the spacing fixed head 41 for image sensor support plate 1 and insert the track of placing.The setting of spacing fixed head can make support plate fix, and is difficult for stress deformation when ejecting.Alignment pin 42 is used for regulating the height gap between control fixed head 5 and the intermediate plate 4, according to the different settings of product ejection height not of the same race.
