Abstract

The utility model discloses a kind of Electronic Packaging class pipe cap sandblasting fixtures to pass through the fixation to pipe cap, low efficiency not easy to operate in pipe cap sandblasting procedures to solve, the ropy problem of sandblasting.Adjust the quantity of a pipe cap sandblasting and the control to pipe cap on horizontal X direction by the position of adjusting nut position, the control by six roots of sensation fixed wire to pipe cap on horizontal Y and vertical Z-direction ensure that and all be in setting position to blast tube cap.Finally fixed wire is taken out and completes assembly, avoids fixed wire in sandblasting procedures and impacts the quality for improving blasting craft to pipe cap surface.It can according to need any spacing for adjusting clamping plate, six roots of sensation fixed wire ensures the loosening of pipe cap in assembling process and falls problem, it greatly increases the production efficiency, it is compared with the single nut cap sandblasting of man-hour manually hand-held and saves plenty of time and cost of labor, most importantly sandblasting quality increases substantially, and can ensure that the reliability of subsequent production.

Description

A kind of Electronic Packaging class pipe cap sandblasting fixture

Technical field

The utility model relates generally to the field of surface treatment of Electronic Packaging class pipe cap, in particular to a kind of No. ten steel punching presses The surface sand-blasting fixture of pipe cap.

Background technique

Microelectronics, hydrid integrated circuit, multi-chip module etc. are in Aeronautics and Astronautics, ship, electronics, communication, radar, weapons Equal fields using more and more extensive, and Electronic Packaging is just that these fragile electronic products of powerful but body and electronics are set It is standby that necessary protection is provided.The electronic chip and circuit of various different performances, different appearances are adapted in Electronic Packaging field, There are various Metal Packaging shells.And there are the needs of a kind of encapsulating package by bottom plate and protection chip with chip The pipe cap quality that welds, and weld directly affect the use reliability of equipment, so the pre-electroplating treatment of pipe cap is It is very important.It is not only related to the plating quality of pipe cap, also has with the use reliability of later period electronic product very big Relationship.

Utility model content

The purpose of this utility model is to provide a kind of Electronic Packaging class pipe cap sandblasting fixtures, to overcome the prior art not Foot.

A kind of Electronic Packaging class pipe cap sandblasting fixture, for processing encapsulation class pipe cap, including two pieces of clamping plates, four screw rods With four fixed wires, setting sets that there are four small there are four large through-hole in the middle part of the clamping plate on four angles of the clamping plate Through-hole, the rounded setting of small through hole, the screw rod pass through the large through-hole, and fixed on the every screw rod there are two spiral shells Mother, the every two nut are located at the two sides of the clamping plate, and for fixing the screw rod, one end of the fixed wire is in 90 degree of bendings of 90 degree of bendings, the fixed wire are placed towards the center of clamping plate.

Preferably, the diameter of the large through-hole is 6mm.

Preferably, the diameter of the small through hole is 4mm.

Beneficial effect brought by the utility model is:

A kind of Electronic Packaging class pipe cap sandblasting fixture of the utility model, is bolted two clamping plates and 16 by four Root nut is fixed, and can adjust the spacing of clamping plate arbitrarily not only to control sandblasting and place the quantity of pipe cap, but also can pass through two The adjusting of nut is to fasten the pipe cap placed.Six roots of sensation fixed wire has a limitation to pipe cap by four direction, prevents Pipe cap is not in slide or fall phenomenon during being packed into fixture.This mold improves production efficiency in loading procedure, And effectively limit pipe cap be difficult to grab in sandblasting procedures, the few problem low with production efficiency of a sandblasting quantity.

Detailed description of the invention

The utility model is described in further detail below in conjunction with attached drawing.

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the utility model assembling process schematic diagram.

Fig. 3 is that the utility model fixture completes assembly preparation sandblasted structures schematic diagram.

The corresponding label of component names is as follows in figure:

1, clamping plate；2, screw rod；3, nut；4, fixed wire；5, large through-hole；6, small through hole；7, pipe cap.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and embodiments:

As the embodiment of Electronic Packaging class pipe cap sandblasting fixture described in the utility model, as shown in Figure 1, a kind of electronic seal Class pipe cap sandblasting fixture, including two clamping plates 1 are filled, there are four diameter 6mm large through-hole 5 and six diameter 2mm small through hole thereon 6, four screw rods, 2,16 nuts 3, and respectively there are two nut 3 and six roots of sensation fixed wires 4 across 2 two sides of screw rod of clamping plate 1, Gu Fixed thread one end is in 90-degree bending.

As shown in Fig. 2, a kind of Electronic Packaging class pipe cap sandblasting fixture assembling process schematic diagram, first integrally places mold In one piece of plane, clamping plate is opened to maximum by adjusting nut position as far as possible, then catches the bending part of fixed wire, will be fixed Silk extraction, is once put into remaining unrooted fixed wire in the way of each one of front and back sides for pipe cap by mode as shown in the figure and is formed Slot in, then by rotating nuts reduce two clamping plates spacing finally extract all fixed wires out to clamp pipe cap, it is complete At the assembly work before sandblasting, state as shown in Figure 3.

This fixture can according to need any spacing for adjusting clamping plate, in assembling process to adjust according to the actual situation Whole primary required sandblasting quantity, meets different production requirements, six roots of sensation fixed wire ensures the pipe cap in assembling process Loosen and fall problem, greatly increase the production efficiency, with the single nut cap sandblasting of man-hour manually hand-held compared to save the plenty of time and Cost of labor, it is most important that sandblasting quality increases substantially, and can ensure that the reliability of subsequent production.
