Description

Technical Field

[0001] This application relates to loading during component processing, specifically to a layer loading and transfer device for layering ceramic substrates before and after cleaning, screen printing, and sintering in the field of AMB ceramic copper clad laminate technology. Background Technology

[0002] AMB is short for Active Metal Brazing. Active metal brazing is generally made as follows: First, active metal brazing material is coated on the surface of a ceramic substrate by screen printing. Then, it is clamped with an oxygen-free copper sheet and welded at high temperature in a vacuum brazing furnace. Then, the pattern is etched to make the circuit. Finally, the surface pattern is chemically plated.

[0003] Before printing the paste, ceramic substrates need to be cleaned. Currently, horizontal cleaning lines are mostly used to complete this process. After cleaning, the ceramic substrates need to be stacked again, which can easily cause scratches and dirt to reappear.

[0004] Since the paste on the ceramic substrate is liquid when printing is completed, it needs to be dried immediately, otherwise the back side cannot be printed. The drying time is long, and the paste is easily damaged after drying. Using a tunnel oven for drying requires a longer oven body and a more complex structure for ventilation and scratch prevention, which increases the cost significantly. After drying, the substrate needs to be stacked again, which can easily cause scratches and dirt.

[0005] Before the sintering of the ceramic copper-clad laminate, the ceramic substrates coated with paste after printing and drying also need to be stacked, which can easily cause scratches and dirt.

[0006] If drying equipment such as a blower drying oven or a vacuum drying oven is used, it is necessary to consider whether the size of the drying oven cavity matches the size of the ceramic substrate layer loading device. If there are many layers and the ceramic substrates are densely packed, placing too many layers will lead to incomplete drying.

[0007] Therefore, there is a need for an apparatus that can maintain the ceramic substrate in layers during cleaning, printing, drying, and stacking of ceramic substrates. Utility Model Content

[0008] The purpose of this application is to overcome the aforementioned deficiencies of the prior art and provide a highly efficient device for maintaining the ceramic substrate in layers during cleaning, printing, drying, and stacking of components (e.g., ceramic substrates). Furthermore, this layered loading and transfer device is versatile across the cleaning, printing, drying, and stacking processes. This layered loading and transfer device can be used inverted during the printing process to facilitate back-side printing. This layered loading and transfer device can accommodate components of different sizes. This layered loading and transfer device can withstand temperatures up to 200°C. This layered loading and transfer device ensures the strength of the main body while providing a large exposed area on the front, back, left, right, top, and bottom sides.

[0009] To achieve the above objectives, this application provides a layered loading and transfer device for layered loading of components to be loaded. The layered loading and transfer device includes: an upper end plate and a lower end plate arranged opposite to the upper end plate, and at least two guide posts and at least one stop post detachably connected between the upper end plate and the lower end plate. Each guide post has a plurality of grooves spaced apart along its axial direction. The upper and lower surfaces of each groove form upper and lower object surfaces for placing components. The stop post and the upper or lower object surface together support and define the position of the component to be loaded. The width of the groove along the axial direction of the guide post is greater than the thickness of the component to be loaded. After being loaded into the layered loading and transfer device, each component to be loaded is spaced apart from each other along the axial direction of the guide post.

[0010] Optionally, the column includes a plurality of columns arranged in two parallel rows, with the two rows respectively located on the left and right sides of the upper end plate and the lower end plate. The bottom of the groove of the column arranged on the left side forms a left blocking surface, and the bottom of the groove of the column arranged on the right side forms a right blocking surface. A loading space with a loading width is defined between the left and right blocking surfaces, and the loading width is equal to or greater than the width of the component to be loaded.

[0011] Optionally, the stop post is arranged on the rear side of the upper end plate and the lower end plate to form a rear blocking surface.

[0012] Optionally, the upper end plate and the lower end plate have the same size and shape.

[0013] Optionally, the component to be loaded may be a copper sheet, ceramic sheet, or spacer with different specifications.

[0014] Optionally, the upper and lower end plates are provided with notches for gripping the layered loading and transfer device.

[0015] The notches mentioned therein include two or more, and the notches are rectangular in shape.

[0016] Optionally, the upper end plate and the lower end plate have mounting holes on their rear sides, and the stop post is fixed to the inner surface of the upper end plate and the lower end plate by fasteners passing through the mounting holes.

[0017] Optionally, the upper and lower end plates are provided with elongated holes extending in the left and right directions at their left and right ends. Bolts are inserted into the elongated holes to fix the piercing post between the upper and lower end plates. The elongated holes and bolts together adjust the position of the piercing post corresponding to different widths of the components to be loaded.

[0018] Optionally, both the mounting hole and the elongated hole are countersunk holes or stepped holes designed to fully accommodate the fastener.

[0019] By adopting the above-mentioned solution of this application, the layered loading and transfer of components such as ceramic substrates can be effectively realized, the number of handling operations can be reduced, the components can be guaranteed to be universal in cleaning, printing, drying and stacking processes, and scratches and dirt can be avoided from being stacked again.

[0020] The layered loading and transfer device of this application has a simple structure, is easy to operate, and is structurally stable. It avoids the stacking of components, realizes layered loading of components after printing, reduces scratches and damage to components and printing paste layers, improves product yield and efficiency, enables shared use between processes, reduces human error rate, and lowers workload.

[0027] Preferred embodiments of this application are described in detail below with reference to examples. Those skilled in the art should understand that these embodiments are not intended to limit this application in any way, and features in the various embodiments can be combined with each other. In different drawings, the same components are represented by the same reference numerals, and for the sake of brevity, some components are omitted, but this does not mean that other components are excluded. It should be understood that the dimensions, scale relationships, and number of components in the drawings are not intended to limit this application.

[0028] Figure 1 A front view of a layered loading and transfer device for layered loading and transfer of components according to this application is shown. As an example, the components described in this application are materials before sintering of ceramic copper-clad laminates, such as ceramic sheets, copper sheets, spacers, etc. Although this application uses this as an example for description, it is not limited to this, but can be used to layered load and transfer various other components.

[0029] The layered loading and transfer device of this application includes an upper end plate 2 and an opposite lower end plate 5, and a series of columns 1 detachably connected between the upper end plate 2 and the lower end plate 5. The series of columns 1 are provided with a plurality of grooves 14 evenly distributed along the axial direction. Each groove 14 extends circumferentially, and its upper and lower surfaces respectively form loading and unloading surfaces 11. The grooves 14 are used to carry the loaded components. The series of columns 1 includes six columns arranged in two rows on the left and right sides of the layered loading and transfer device, defining a loading space for loading the components between the two rows of columns 1 and the upper and lower end plates 2 and 5. Specifically, the bottom surface of the groove 14 fixed on the left side of the inner surface 21 of the upper end plate 2 and the lower end plate 5 forms a left-side blocking surface 12, and the bottom surface of the groove 14 fixed on the right side of the inner surface 21 of the upper end plate 2 and the lower end plate 5 forms a right-side blocking surface 13. The left-side blocking surface 12 and the right-side blocking surface 13 are arranged in parallel, defining a loading width k between them. The width k of the load is greater than or equal to the width of the component to be loaded. The outer surfaces 22 of the upper end plate 2 and the lower end plate 5 are flat without protrusions. The upper end plate 2 and the lower end plate 5 can have the same shape and size and be arranged in parallel. In use, the layered loading and transfer device can be flipped up and down, so that the upper end plate becomes the lower end plate and the lower end plate becomes the upper end plate, and at the same time, the upper and lower surfaces of the components loaded in the device are flipped.

[0030] The ferrule 1 can be made of corrosion-resistant metal material.

[0031] The groove 14 on the cylinder 1 can be formed by performing a machining process known in the art on the cylinder, such as turning or milling. Alternatively, multiple discs can be welded onto the cylinder to form the groove 14 between the discs.

[0032] like Figure 2 As shown, the stop post 3 is fixed to the rear inner surface 21 of the upper end plate 2 and the lower end plate 5, forming a rear blocking surface 31. The front side is the component entry side.

[0033] The stop post 3 can be cylindrical and can be made of the same or different material as the string post 1.

[0034] All the ferrules 1 have the same structure and dimensions. The width of the grooves 14 in the axial direction (or vertical direction) of the ferrule 1 is greater than the thickness of the component to be loaded, so as to easily insert the component to be loaded. Multiple grooves 14 are spaced apart in the axial direction at a certain interval, so that each component to be loaded is separated from each other vertically after being loaded, thereby achieving layered loading and avoiding scratches caused by collisions between components.

[0035] Since the upper end plate 2 and the lower end plate 5 have the same shape and size, the following description will only take the upper end plate 2 as an example.

[0036] like Figure 3As shown, the upper plate 2 is rectangular, with two or more rectangular notches 4 inside, for the operator's hand or tools to insert and grasp the layered loading and transfer device. The shape of the notches 4 can be set to various different shapes as needed, such as rectangles, circles, etc.

[0037] The upper end plate 2 has a row of elongated holes 23 on the left side and a row of elongated holes 24 on the right side. The elongated holes 23 on the left side and the elongated holes 24 on the right side are arranged in parallel. There is a round hole 25 on the rear side of the upper end plate 2, and the front side is the side where the loading component enters.

[0038] The end of the spool 1 is machined with threaded holes, and screws are used to fasten the spool 1 to the left and right sides of the upper end plate 2 and the lower end plate 5. The elongated holes 23 and 24 extend in the left and right directions of the layered loading and transfer device. For example, the elongated holes extend along the y direction in the figure to adjust the position of the left blocking surface 12 and the right blocking surface 13, thereby adjusting the load width k to accommodate different sized components to be loaded, such as copper sheets, ceramic sheets, stainless steel sheets, etc.

[0039] The round hole 25 is a through hole, and the end of the stop post 3 is machined with a threaded hole. The stop post 3 is fastened to the rear side of the upper end plate 2 and the lower end plate 5 by screws.

[0040] like Figure 4 As shown, the main body of the layered loading and transfer device is a cuboid, while the connecting column 1 and the baffle column 3 are both cylinders. However, this application is not limited to this, and can be of other shapes.

[0041] For example, the connecting post 1 and the stop post 3 can be cubes, irregular columns, etc., as long as they can define the boundary load-bearing components.

[0042] The number of 1-pins is not necessarily 6; it can be changed according to actual needs, and can be more or less than 6. The number of 3-pins is not necessarily 2; it can be changed according to needs, and can be more or less than 2.

[0043] The plurality of grooves 14 can be distributed along the entire length of the post 1 between the upper end plate 2 and the lower end plate 5.

[0044] Or, it could be like this Figure 1 As shown, on the column 1, there are sections 15 without grooves 14 at positions near the upper end plate 2 and the lower end plate 5, respectively, such that the uppermost groove 14 and the lowermost groove 14 are separated from the upper end plate 2 and the lower end plate 5 by a distance sufficient for a hand or tool to grip the layering device transfer device and to load and unload components.

[0045] The round holes 25 for mounting the stop post 3 and the elongated holes 23 and 24 for mounting the connecting post 1 on the upper end plate 2 and the lower end plate 5 can all be set as countersunk holes or stepped holes to accommodate fasteners such as bolts, so that after assembly, the outer surfaces of the upper end plate 2 and the lower end plate 5 of the layered loading and transfer device are flat and supportable surfaces, with no protrusions protruding beyond the outer surface.

[0046] Furthermore, the layered loading and transfer device of this application can be used upside down without considering the orientation of the layered loading and transfer device. This is achieved by having multiple columns 1 with the same structure, the same number of grooves 14, the grooves 14 being evenly distributed along the columns 1, and the upper end plate 2 and the lower end plate 5 having the same shape, structure and size.

[0047] Figure 4 A perspective view of the layered loading and transfer device is shown in its state without loading components.

[0048] Figure 5 A perspective view of the layered loading and transfer device with components is shown.

[0049] The following describes the process of loading components using the layered loading and transfer device of this application. For example... Figure 5 As shown, the component to be loaded, 35, is exemplified as a ceramic sheet with a rectangular cross-section. First, in the first step, the ceramic sheet 35 is aligned with the first layer width k of the layered loading and transfer device. Force is applied to insert the ceramic sheet until one end touches the stop post 3, at which point it is released and placed onto the loading surface 11 by gravity. The remaining ceramic sheets are inserted sequentially, thus completing the loading of the ceramic sheets. At this point, there are gaps between the ceramic sheets 35, and they are aligned with each other, achieving layered loading. Then, the layered loading and transfer device uses the notches 4 on the upper end plate 2 and the lower end plate 5 to grab and transfer the ceramic sheets to other equipment in the process, such as a cleaning line for cleaning the ceramic sheets, a printing press for printing paste on the ceramic sheets, a drying oven for drying the printed ceramic sheets, and a stacking machine for multi-layer stacking.

[0050] In the printing paste process, the layered loading and transfer device needs to be inverted so that both sides of the ceramic sheet can be printed.

[0051] Although Figure 5 The illustration depicts a layered loading and transfer device for loading ceramic sheets, but this application is not limited to this and can also be used to load various other components.

[0052] Although Figure 5 The illustration shows a layered loading and transfer device that loads 35 ceramic pieces, but this application is not limited to this; the number of pieces can be greater than or less than 35, and can be adjusted according to actual needs.

[0053] The materials used for the various components of the layered loading and transfer device can be multiple or a single type. These materials can be high-temperature resistant, acid and alkali resistant, lightweight, or soft and scratch-resistant.

[0054] The principles, features, and advantages of this application have been shown and described above. The layered loading and transfer device of this application can be used in multi-process equipment with only one loading, enabling layered loading of ceramic sheets, avoiding scratches and breakage, significantly improving the yield of pre-sintering semi-finished products of copper-clad ceramic products, increasing processing efficiency and yield, and facilitating large-scale use.

[0055] The present application has been described in detail above with reference to specific embodiments. Obviously, the above description and the embodiments shown in the accompanying drawings should be understood as exemplary and not as limiting the present application. Those skilled in the art can make various modifications or alterations without departing from the spirit of the present application, and such modifications or alterations do not depart from the scope of the present application.
