Description

Technical Field

[0001] The utility model relates to the technical field of ceramic substrate production, and relates to an auxiliary trolley for automatic exposure of ceramic substrates. Background Art

[0002] High-power semiconductor modules are widely used in fields such as electric locomotives, electric vehicles, and photovoltaic solar energy. With the increasing integration and power of high-power modules, the heat generated by semiconductor devices shows an upward trend. Currently, the method of sintering and bonding a metal with excellent electrical and thermal conductivity and a ceramic such as nitride with good insulation performance to form a copper-clad ceramic substrate is widely used in power semiconductors to solve the heat dissipation problem of power semiconductor devices.

[0003] In the production process of copper-clad ceramic substrates, the exposure process is an important part. In the existing production process, manual handling is usually used to transfer ceramic substrates before and after the exposure process, often resulting in accidental dropping of ceramic substrates, and thus product damage and scrapping. Summary of the Utility Model

[0004] The utility model provides an auxiliary trolley for automatic exposure of ceramic substrates to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: an auxiliary trolley for automatic exposure of ceramic substrates, comprising: a trolley, wherein universal wheels are arranged at the lower end of the trolley and a placing mechanism is arranged at the upper end of the trolley. The placing mechanism comprises a mounting rack fixedly arranged at the upper end of the trolley, a transport roller rotatably arranged between the mounting racks, and a limiting seat fixedly arranged at the upper end of the transport roller. The limiting seat comprises a limiting column arranged on the mounting rack, a limiting groove is arranged at the top end of the limiting column, and a limiting rod is arranged in the limiting groove.

[0006] Further improvement, two groups of the placing mechanisms are arranged, and the two groups of placing mechanisms are symmetrically arranged at the upper end of the trolley.

[0007] Further improvement, a rotating rod is arranged in the limiting groove, a rotating hole is arranged through the bottom end of the limiting rod, and the limiting rod is rotatably arranged on the rotating rod through the rotating hole.

[0008] Further improvement, a pushing handle is arranged at the side end of the trolley.

[0009] Further improvement, two groups of the pushing handles are arranged, and the two groups of pushing handles are symmetrically arranged on both sides of the trolley.

[0010] Further improvement, the cross-section of the mounting rack is U-shaped.

[0011] For further improvement, eight sets of limit seats are provided for each placement mechanism.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. During the actual use of the utility model, the trolley is pushed to the film pressing process, and the ceramic substrate after film pressing is placed in the material treatment frame. Then, the material treatment frame is placed on the transport rollers, and the material treatment frame is pushed so that each group moves to the set position. Again, the limit rod is placed in the limit slot for limiting. After the limiting is completed, the trolley is pushed to the automatic exposure workbench for exposure operation. The method of transporting by the trolley replaces manual handling, avoiding damage and scrapping caused by accidental dropping of the ceramic substrate during handling. At the same time, the movement of the material treatment frame on the trolley is realized through the transport rollers, effectively reducing the working intensity and improving the working efficiency.

[0014] 2. The utility model realizes the front and rear limiting of the ceramic substrate through the rotating rod, avoiding the mutual collision or dropping of the ceramic substrates during transportation. There is a gap between adjacent ceramic substrates, improving the subsequent exposure effect. The structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
