Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ceramic copper-clad lining plate production, in particular to a horizontal line jig for surface treatment of ceramic copper-clad lining plates. Background Art
[0002] Ceramic copper-clad laminates, due to their high insulation and thermal conductivity, have become an essential, key foundational material for power module packaging in the power electronics field. Made by sintering ceramic substrates of varying thicknesses and materials with copper foil on both sides, their total thickness typically does not exceed 2mm. Their processing involves numerous surface treatment processes, particularly heat treatment. Due to differences in the thermal expansion coefficients of the substrates, copper foil, and other base materials, as well as differences in the positive and negative copper on each side, ceramic copper-clad laminates are prone to stress imbalance after cooling from heat treatment and after etching to form patterns, resulting in warping of varying shapes. This warping is further exacerbated with the addition of additional heat treatment steps.
[0003] The current surface treatment process of ceramic copper-clad lining boards generally adopts two methods: horizontal lines or vertical lines. Due to the limited permeability of horizontal lines, the raised parts of the warped ceramic copper-clad lining boards are easily squeezed by the rollers within the horizontal lines or adhered to foreign matter on the rollers to form bad marks; especially on the silver-plated horizontal lines, the raised silver-plated areas due to warping are very likely to come into contact with the rollers to form color differences in the marks, resulting in bad scrap. Utility Model Content
[0004] In order to solve the problems of the prior art, the utility model provides a horizontal line fixture for surface treatment of ceramic copper-clad lining plates.
[0005] The purpose of the utility model can be achieved through the following technical solutions: A horizontal line jig for surface treatment of ceramic copper-clad lining boards, comprising: a jig body, a placement cavity is provided through the jig body, a placement platform is provided in the placement cavity, the placement platform includes a first support platform provided around the placement cavity and a second support platform provided in the middle of the placement cavity, the second support platform is mirror-set in two groups, the adjacent first support platform and second support platform form a placement groove, the left and right sides of the placement cavity are provided with first arc-shaped pick-up and place grooves, and the first arc-shaped pick-up and place grooves are mirror-set in two groups up and down.
[0006] As a further improvement, second arc-shaped placing and taking grooves are provided on the upper and lower sides of the placement cavity.
[0007] As a further improvement, the placement cavities are symmetrically arranged in two groups.
[0008] As a further improvement, the material of the fixture body is glass fiber board with a thickness of 4 mm.
[0009] As a further improvement, the depth of the placement platform is 3 mm.
[0010] As a further improvement, the edge of the fixture body is provided with a chamfer.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The utility model has the advantages of simple design, convenient processing, easy operation, recyclability, long service life and low cost. The middle part of the fixture body is hollowed out to form a placement cavity, and the four corners are subjected to a lowering treatment to form a placement platform for carrying and assisting in fixing the ceramic copper-clad lining plate, so that the copper foil surface of the ceramic copper-clad lining plate is fully in contact with the potion in the horizontal line, ensuring the surface treatment effect. When passing through the horizontal line, the placement platform formed by the lowering treatment of the four corners makes the ceramic copper-clad lining plate as a whole lower than the upper surface of the fixture, avoiding its contact with the roller and thus avoiding the ceramic copper-clad lining plate from having a bad mark after the chemical treatment of the horizontal line. At the same time, it plays a role of limiting, so that the position of the ceramic copper-clad lining plate is relatively fixed when entering and exiting the horizontal line, and will not deviate significantly during the forward process, which provides great convenience for the introduction of automatic material collection and unloading equipment in the later stage.
[0013] 2. The first arc-shaped placement grooves are provided on the left and right sides of the placement cavity of the utility model to facilitate the staff to take and place the ceramic copper-clad lining board on the fixture. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0018] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0019] Below with reference to the embodiment and the attached Figures 1 and 2 , the technical solution of the utility model is further elaborated.
[0020] Example 1
[0021] A horizontal line jig for surface treatment of ceramic copper-clad lining boards, comprising: a jig body 1, a placement cavity 11 being provided through the jig body 1, a placement platform 12 being provided in the placement cavity 11, the placement platform 12 comprising a first support platform 121 provided around the placement cavity 11 and a second support platform 122 provided in the middle of the placement cavity 11, two groups of the second support platforms 122 being mirror-imaged, the adjacent first support platforms 121 and second support platforms 122 forming a placement slot, first arc-shaped pick-up and placement slots 13 being provided on the left and right sides of the placement cavity 11, and two groups of the first arc-shaped pick-up and placement slots 13 being mirror-imaged up and down.
[0022] like Figures 1 and 2 As shown, Figures 1 and 2 As shown, the utility model has the advantages of simple design, convenient processing, easy operation, recyclability, long service life and low cost. The middle part of the fixture body 1 is hollowed out to form a placement cavity 11, and the four corners are lowered to form a placement platform 12, which is used to carry and assist in fixing the ceramic copper-clad lining board, so that the copper foil surface of the ceramic copper-clad lining board is fully in contact with the potion in the horizontal line, ensuring the surface treatment effect. When passing through the horizontal line, the placement platform 12 formed by the four corners lowering treatment makes the ceramic copper-clad lining board as a whole lower than the upper surface of the fixture, avoiding its contact with the roller and thus avoiding the ceramic copper-clad lining board from having a bad mark after the chemical treatment of the horizontal line. At the same time, it plays a role of limiting, so that the position of the ceramic copper-clad lining board is relatively fixed when entering and exiting the horizontal line, and will not deviate significantly during the forward process, which provides great convenience for the introduction of automatic material collection and unloading equipment in the later stage.
[0023] The left and right sides of the placement cavity 11 are provided with first arc-shaped placement grooves 13 to facilitate the staff to take and place the ceramic copper-clad lining board on the fixture.
[0024] Example 2
[0025] The difference between Example 2 and Example 1 is that second arc-shaped pick-up and placement grooves 14 are provided on the upper and lower sides of the placement cavity 11. The second arc-shaped pick-up and placement grooves 14 facilitate workers to pick up and place the ceramic copper-clad lining board on the fixture.
[0026] Example 3
[0027] The difference between Example 3 and Example 1 is that the placement chambers 11 are symmetrically arranged in two groups, which increases the number of ceramic copper-clad lining boards processed in a single time, thereby improving production efficiency.
[0028] Example 4
[0029] The difference between Example 4 and Example 1 is that the material of the fixture body 1 is a glass fiber board with a thickness of 4 mm, and the depth of the placement platform 12 is 3 mm. In actual conditions, the total thickness of the ceramic copper-clad lining board generally does not exceed 2 mm. The 3 mm drop height makes it possible to adapt to ceramic copper-clad lining boards with large warping, so that ceramic copper-clad lining boards with large warping do not need to be leveled and can be directly placed in the horizontal line for chemical treatment, saving corresponding costs.
[0030] Example 5
[0031] The difference between Example 5 and Example 1 is that the edge of the jig body 1 is provided with a chamfer to reduce the risk of mechanical injury. At the same time, the setting of the edge chamfer makes the edge of the jig thinner, making it more convenient when it reaches the horizontal line, improving the passability of the jig within the horizontal line and reducing the risk of carding.
[0032] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
