Description

Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to a sheet inserting auxiliary jig used for pre-processing of copper sheets. Background Art

[0002] Copper ceramic substrates, as a core insulating substrate component, are widely used in the field of power semiconductor device packaging. Copper-clad ceramic substrates are patterned through a process of sintering, lamination, exposure, development, and etching, and are then coated with a metal coating as needed.

[0003] During the production process of copper-clad ceramic substrates, the copper sheets need to be cleaned and other pre-treatments, and need to be placed in a dedicated plug-in rack. The plug-in rack is open and uses serrated stripes to fix the products, so as to ensure full contact with the solution as possible. Therefore, two pairs of upper and lower sockets are designed to avoid insufficient fluidity of the solution and reduce the risk of residual solution inside the sockets.

[0004] However, this structure also means that during the insertion process, the copper sheet must be aligned with the upper and lower pairs of sockets respectively, which can easily lead to crooked insertion, resulting in unsatisfactory copper sheet processing results and low efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an auxiliary fixture for inserting copper sheets for pre-processing, which simplifies the operation and allows the copper sheets to be directly inserted by simply aligning them with the two corresponding slots of the two sets of side plates, thereby improving work efficiency.

The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] like Figures 1 to 3 As shown, a sheet inserting auxiliary jig for copper sheet pretreatment processing includes a base plate 1 and two sets of side plates 2. The two sides of the base plate 1 are rotatably connected to the two sets of side plates 2. A sheet inserting rack 3 is placed above the base plate 1. The inner sides of the two sets of side plates 2 are fitted with the two sides of the sheet inserting rack 3. The side plates 2 and the base plate 1 are both provided with an array of slots 4 arranged at equal intervals on one side of the sheet inserting rack 3.

[0032] The plug-in board rack 3 includes two groups of side plug-in boards 5 and connecting beams 6. At least two groups of connecting beams 6 are symmetrically arranged on both sides and the bottom of the side plug-in boards 5. Each group of connecting beams 6 has a corresponding array of serrated equidistantly spaced plug-in holes 7 on the inner side. The plug-in holes 7 are arranged in a one-to-one correspondence with the slots 4.

[0033] Two groups of connecting grooves 8 are evenly spaced apart on one side of the two groups of side panels 2 and on both sides of the bottom panel 1 . The connecting grooves 8 of each group of side panels 2 are staggered with the connecting grooves 8 on the corresponding side of the bottom panel 1 .

[0034] The connection between the side panels 2 and the bottom panel 1 is provided with connection holes 9 along the setting direction of the connection grooves 8. The side panels 2 and the bottom panel 1 are installed in a staggered manner with the connection grooves 8, and are connected and rotated by a fixing rod 10 passing through the connection holes 9.

[0035] In the working state, the maximum rotation angle of the two sets of side panels 2 is 90°, which can flexibly realize the closing and opening of the plug-in board rack 3.

[0036] A card slot 11 is provided in the base plate 1 and the two sets of side plates 2 corresponding to the connecting beam 6. The height of the card slot 11 is the same as the height of the connecting beam 6. The setting direction of the card slot 11 is perpendicular to the setting direction of the slot 4. The slot 4 and the socket 7 on the connecting beam 6 are set at the same height.

[0037] The length of the connecting beam 6 is the same as that of the bottom plate 1 and the two sets of side plates 2 , and the inner sides of the side insert plates 5 are closely attached to the front and rear ends of the bottom plate 1 and the side plates 2 .

[0038] like Figure 4 As shown, the two ends of the fixing rod 10 are provided with limiting plugs 12, and the limiting plugs 12 at both ends can be realized.

[0039] like Figure 2 As shown, the back of the two sets of side panels 2 are both provided with a herringbone-shaped groove 13 to facilitate closing and opening the two sets of side panels 2.

[0040] The bottom plate 1 and the two sets of side plates 2 are all made of polyoxymethylene, which prevents the corrosive liquid that may be carried on the plug-in board rack from damaging the fixture while ensuring the hardness and structure of the fixture itself.

[0041] The workflow of this utility model is:

[0042] like Figure 1 and 2 As shown, first, the two sets of side panels 2 and the bottom panel are cross-connected and assembled through the connecting grooves 8, and then connected through the fixing rods 10. Figure 5 As shown, when in use, the bottom of the plug-in board rack 3 is placed on the bottom plate 1, and the connecting beam 6 at the bottom of the plug-in board rack 3 is clamped in the clamping groove 11 of the bottom plate 1. Figure 6 As shown, the two sets of side panels 2 on both sides are rotated and closed at the same time. At this time, the slots 4 on the side panels 2 and the bottom panel 1 correspond to the sockets 7 of the connecting beam 6 of the plug-in plate rack 3. When inserting the copper sheet, you only need to align it with the two corresponding slots 4 of the two sets of side panels 2 and put it in directly. After the plug-in plate rack 3 is filled with copper sheets in turn, open the two sets of side panels 2 on both sides, and the plug-in plate rack 3 filled with copper sheets can be taken out for subsequent copper sheet pretreatment.

[0043] The utility model guides the copper sheet to assist in inserting the board rack through structural design, so that when inserting the board, there is no need to pay attention to whether each slot is aligned. When inserting the board, it is only necessary to align the copper sheet with the two corresponding slots of the two groups of side plates and then directly insert the board, thereby improving work efficiency.

[0044] The edge of the fixture of the utility model strictly fits the plug-in board rack, and the original plug-in board rack can be used without structural changes, and no relative displacement occurs during use, which is more stable.

[0045] The utility model adopts an openable and closable structure, so one fixture can correspond to multiple plug-in racks, and has better applicability.

[0046] The utility model limits the angle of the opening and closing structure of the two sets of side panels through structural design, so that it can be stably placed on the work surface.

[0047] The combined jig of the bottom plate and the two sets of side plates of the utility model is made of polyoxymethylene material, which prevents the jig from being damaged by corrosive liquids that may be carried on the plug-in board rack, while ensuring the hardness and structure of the jig itself.
