It may be evident, however, that one or more embodiments may be practiced without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

Referring to fig. 1-2, the simple device for flattening a frame of the present utility model includes an H-shaped support plate 1, and may be manufactured into an H-shaped structure as needed for easy installation. The left wing plate 1-1 and the right wing plate 1-1 of the supporting plate 1 are fixedly connected with the fixed base plate 2, the first linear flange bearing seats 3 and the first guide shafts 4 are assembled at the two ends of the middle plate 1-2 of the supporting plate 1, the connecting plates 5 are assembled at the top ends of a pair of first guide shafts 4, and during specific implementation, the telescopic rod ends of the air cylinders 6 are fixedly connected with the connecting plates through the limiting columns 14 and the gaskets 15. The connection plates 5 are arranged parallel to the intermediate plate of the support plate 1. The middle position of the middle plate 1-2 is provided with a cylinder 6, and the telescopic rod of the cylinder 6 is correspondingly connected with the connecting plate 5. The middle plate 1-2 is provided with a pair of spring studs 7, and the pair of spring studs 7 are symmetrically arranged on two sides of the cylinder 6. The other ends of the pair of spring studs 7 are opposite to the bottom of the connecting plate 5. The bottom of the middle plate 1-2 is provided with a discharge fixing plate 8, the discharge fixing plate 8 is distributed along the axial direction of the supporting plate 1, the discharge fixing plate 8 is connected with the bottom end of the first guide shaft 4, the bottom of the discharge fixing plate 8 is provided with a discharge guide plate 9, and the lower part of the discharge guide plate 9 is the position of frame discharge. The vertical buffer unit is arranged between the unloading guide plate 9 and the unloading fixing plate 8, when the air cylinder 6 drives the connecting plate 5 to compress downwards, the first guide shaft 4 pushes the unloading fixing plate 8 and the unloading guide plate 9 to move downwards so as to flatten the frame, at the moment, the vertical buffer unit can provide a certain reverse elasticity upwards, the air cylinder 6 is prevented from being excessively stressed instantaneously, the bottom frame is damaged, and accordingly a reverse buffer effect is achieved.

According to the simple device for flattening the frame, when the frame is grabbed and enters the die, the air cylinder 6 drives the first guide shaft 4 to move up and down, the unloading guide plate 9 is pressed against the frame by the aid of the pressure of the air cylinder 6, stroke control is convenient, one-step pre-pressing action is added after the frame is put down by the manipulator, preheating of the frame is comprehensive, subsequent plastic packaging steps are fully conducted, and quality of a chip manufacturing process is improved.
