Abstract

The utility model provides a feeder anti-blocking device of adhesion equipment. A pull-in plate is disposed on the frame, supporting blocks are arranged on two ends of the frame and the pull-in plate and supporting bars used to support the frame are respectively disposed at two ends below the frame. The supporting bars are of L-shaped supporting bars formed by a cross bar and a vertical bar, an eccentric shaft is disposed between the supporting blocks and the cross bar and a bearing is disposed at the tail end of the eccentric shaft. Bearing slide rails are respectively arranged below the pull-in plate on two ends and the bearings cling tightly to the lower portions of the bearing slide rails. The tail ends of the cross bar is connected with the supporting blocks through a arranged tension spring, and one end of the tension spring is fixed on the supporting blocks while the other end of the tension spring is connected with the tail end of the cross bar. The feeder anti-blocking device of the adhesion equipment can achieve an anti-blocking purpose, effectively prevent blocking when feeding and avoid financial losses caused by frame deformation. In addition, the feeder anti-blocking device of the adhesion equipment is beneficial for automatic production, improving work efficiency of production personnel and further reducing production cost.

Description

A kind of loader anti-sticking materials device of bonding die equipment

Technical field

The utility model relates to semiconductor packages bonding die equipment, particularly a kind of loader anti-sticking materials device of bonding die equipment.

Background technology

In the existing semiconductor die package process, material process on having on the loader need be pulled out the pulling-on piece plate of tape frame.

In the last material process, normally adopt the mode of both sides blend stop, the operation of middle arm-tie to realize material loading earlier.

In carrying out the whole process of arm-tie material loading, not only material loading gets stuck easily, and because the polytropy of each size of framework; Often be out of shape when causing drawing framework; The then generation because frame deformation causes getting stuck more easily, and distortion framework need do over again or scrap, and also will incur loss through delay and make the duration; Production efficiency is lower, and brings certain cost allowance.

The utility model content

The utility model is for solving the problems of the technologies described above; A kind of loader anti-sticking materials device of bonding die equipment is provided, can have realized preventing the purpose that gets stuck from effectively preventing to get stuck in the time of can reaching material loading; Prevent the economic loss that frame deformation causes; And be beneficial to automated production, to improve producers' operating efficiency, further reduce production costs.

The technical scheme of the utility model is following:

A kind of loader anti-sticking materials device of bonding die equipment; The pulling-on piece plate is installed on the framework; It is characterized in that: the two ends that also comprise the back-up block that is positioned at framework and pulling-on piece plate two ends, are positioned at below the framework are respectively arranged with the support bar that is used for support frame; The support bar of the L type that said support bar is made up of cross bar and montant is provided with eccentric shaft between back-up block and the cross bar, and eccentric the tip of the axis is equipped with bearing; The below of pulling-on piece plate is positioned at two ends and is separately installed with a bearing slide rail, and bearing slide rail below is close to bearing; Simultaneously, the end of cross bar is connected with back-up block through the extension spring that is provided with, and an end of said extension spring is fixed on the back-up block, and the other end links to each other with the end of cross bar.

Said eccentric shaft through lock-screw fixing with cross bar on.

After this device was installed, framework parallel angle in stock shelf was limited, thereby when print-pulling device pull framework; Can do not blocked, reduce the waste that causes because of frame deformation greatly, improve producers' operating efficiency by block; Needn't be diligent in handling the problem that gets stuck, further reduce production costs.

Said bearing slide rail is the ordinary steel material, length by 2～2.5 times of use frame width, said slide rail bottom surface comprises a plane and an inclined-plane.

The principle of the utility model is:

Framework is placed in the loader, and the pulling-on piece plate is in the process of pull sheet, and the slide rail and the bearing of pulling-on piece backboard face are the state of being adjacent to, and prepares the position pull out at framework, and two support the framework both sides are propped up, and make framework be in parastate; Back-up block is installed bearing through the eccentric shaft on the cross bar of support bar simultaneously, can make bearing and bearing slide rail keep closely contacting, and rotation eccentric axis can be so that bearing moves along the bearing slide rail, so that adjustable support bar height.

The beneficial effect of the utility model is following:

The utility model is for solving the problems of the technologies described above; A kind of bonding die equipment loader anti-sticking materials device is provided, can have realized preventing the purpose that gets stuck from effectively preventing to get stuck in the time of can reaching material loading; Prevent the economic loss that frame deformation causes; And be beneficial to automated production, to improve producers' operating efficiency, further reduce production costs.

Wherein Reference numeral is: 1 support bar, 2 frameworks, 3 back-up blocks, 4 pulling-on piece plates, 5 bearing slide rails, 6 extension springs, 7 bearings, 8 screws, 9 eccentric shafts.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

Shown in Fig. 1-4, the concrete installation steps of the utility model can be:

The first step: setting-up eccentricity axle 9 on back-up block 3, eccentric shaft 9 passes the cross bar of support bar 1, and bearing 7 is installed on the end of eccentric shaft 9.

Second step: bearing slide rail 5 is installed in pulling-on piece plate 4 belows, parallel with pulling-on piece plate 4 both sides end faces.

The 3rd step: extension spring 6 is installed, an end of extension spring 6 is fixed on the back-up block 3, the other end is fixed in the end of the cross bar of support bar 1, and bearing 7 is close on the bearing slide rail 5.

The 4th step: after placing framework 2, pulling-on piece plate 4 is in the tab position state, adjustment eccentric shaft 9 makes support bar 1 top just contact with framework 2 bases, lock-screw 8 fixed eccentric shaft 9.

After framework is put into loader, the pulling-on piece plate the motion process excessively in, the framework angle also thereupon the change; Pulling-on piece process middle frame has kept not on a horizontal plane; After this device was installed, framework can be because of the pulling-on piece plate in the pulling-on piece process, the swing of framework angle; Can not pull framework and cause the phenomenon of frame deformation, thereby reached the purpose of the utility model.
