Embodiment 1

[0022] Embodiment one, with reference to Figure 1-3 , a built-in SMT chip storage rack, including a base plate 2, the top of the base plate 2 is symmetrically welded with side plates 9 on both sides, the two side plates 9 are provided with chute 91 along the vertical end, and the fixed arm 11 The interior is rotationally connected with the roller shaft 14 through the damping shaft 10. On the outer surface of the roller shaft 14, there are four sets of storage boxes 15 equiangularly distributed around its axis along the horizontal end. The surface walls are slidingly connected one by one, and the two damping shafts 10 can slide up and down inside the two chutes 91. On the one hand, the position of the roller shaft 14 can be limited, and the stability of the structure can be improved. On the other hand, it is convenient The lifting movement of the roller shaft 14, the top plate 12 is welded horizontally above the roller shaft 14 and between the two side plates 9, the horizontal...

Embodiment 2

[0023] Embodiment two, refer to figure 1 , the bottom of the bottom plate 2 is welded with a base 8, and the four corners of the bottom of the base 8 are provided with moving wheels 1, the setting of the moving wheels 1 facilitates the movement and transportation of the storage rack, so that the storage rack can be moved to a designated position as required. The location is convenient for the storage and use of SMT patches.

Embodiment 3

[0024] Embodiment three, refer to figure 1 A ball screw 3 is connected between the two side plates 9 through bearing rotation, and a spiral sleeve 4 is symmetrically sleeved on the ball screw 3, and both sides of the top of the two spiral sleeves 4 are respectively connected to the fixed arm through a strut 5 11 The two sides of the bottom are hinged, one end of the ball screw 3 penetrates the side plate 9 and is welded to the rotating rod 6, and the ball screw 3 is welded by two screw screws with opposite thread directions and equal length, through this structure, When rotating the rotating rod 6, the two helical sleeves 4 can move toward or away from each other, so that the two struts 5 change the angle between the ball screw 3 and the fixed arm 11 at the same time. lift drive.

Abstract

The invention discloses a built-in surface mount technology (SMT) chip storage rack which comprises a bottom plate. Side plates are symmetrically welded to two sides of the top part of the bottom plate; sliding chutes are formed in the two side plates along the vertical ends; a ball screw is rotatably connected between the two side plates through a bearing; screw sleeves symmetrically sleeve on the ball screw; two sides of the top parts of the two screw sleeves are hinged with two sides of the bottom part of a fixed arm through support rods; the inner part of the fixed arm is rotatably connected with a roller shaft through a damping rotary shaft; and four groups of storage boxes are equiangularly distributed on the outer surface of the roller shaft around the axis along the horizontal end.According to the built-in SMT chip storage rack provided by the invention, through rotating a rotary shaft, the ball screw rotates, and the two screw sleeves can move according to the face-to-face direction or the separated direction, so that the sizes of the included angles between the two support rods and the ball screw are changed at the same time, the fixed arm is driven to lift up and lowerdown, the roller shaft can be conveniently embedded and stored, dust pollution is avoided, and the convenience in picking and placing is realized.

Description

technical field [0001] The invention belongs to the technical field of SMT patch storage, in particular to a built-in SMT patch storage rack. Background technique [0002] SMT is Surface Mount Technology (Surface Mount Technology), which is the most popular technology and process in the electronic assembly industry. SMT patch refers to the abbreviation of a series of process processes processed on the basis of PCB. PCB is a printed circuit board, and SMT is surface assembly technology (surface mount technology). It is the most popular technology and technology in the electronic assembly industry. craft. Electronic circuit surface assembly technology, known as surface mount or surface mount technology. It is a kind of non-lead or short-lead surface mount components (SMC / SMD for short, Chinese called chip components) mounted on the surface of the printed circuit board or the surface of other substrates, through reflow soldering or dip soldering, etc. The method is a circuit...
