Description

Plate carrier for improving the heat convection effect of the oven

A panel carrier, in particular a panel carrier capable of performing automatic transfer with a machine, wherein the panel of the panel carrier is also automatically transferred through the machine and the top or bottom surface of at least two opposite side frames It is a non-planar structure that enhances the heat convection of the oven.

With the trend of thin and light electrical products, the traditional thick plate circuit board (hard circuit board) has not met the thickness specifications, making the development of thin plates with thickness less than 40μm gradually become the mainstream. As far as the prior art is concerned, the process of the circuit board includes steps of electroplating, etching, water washing, drying and drying. After the circuit board is dried or dried, the circuit board is placed in the temporary storage phase of the circuit board, and a layer of paper is placed between adjacent circuit boards to prevent the circuit board from being contaminated or damaged due to contact. The problem.

However, the disadvantage of the prior art is that the personnel are easily exposed to the circuit board, and the problem that the circuit board is contaminated or damaged is endless. This is because the board is placed in the storage box or the board is removed from the storage box. The board is manually removed or moved. Although the person moves the board, the finger or the fixture is used to pick up the board. The part of the circuit (ie, the inactive area) is provided, but in actual processing, it is inevitable that it will touch the area where the circuit is provided (ie, the effective area), causing the circuit to be contaminated or damaged, and affecting the production yield of the circuit board.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a panel carrier for supporting panels having a thickness of less than 40 μm. The panel carrier of the present invention comprises a main frame and at least one support strip, and the main frame and the at least one support strip are made of an acid-resistant material and are integrally connected.

The main frame is a rectangular hollow frame with four side frames surrounding a hollow area. The at least one support strip spans the hollow region to support the panel. The at least one support strip is disposed at a position corresponding to an ineffective area of the panel.

The bottom surface of the four-sided frame is further provided with two pairs of lateral slots and two pairs of straight slots, and the two pairs of lateral slots and the two pairs of straight slots are respectively disposed laterally and in a straight manner under the bottom surface of the four-sided frame , moving the main frame for the robot arm.

The main feature of the present invention is that the transfer of the plate carrier and the plate can be fully automated. Since the main frame has the inner wall capable of supporting and positioning the plate member, the plate member can be placed in the plate carrier by the suction type mechanical arm, and the groove can break the vacuum state and facilitate The robot arm smoothly removes the plate. Furthermore, the robot arm can extend into the two pairs of lateral slots and the two pairs of straight slots to move the main frame.

Therefore, the transfer of the plate carrier and the plate member can be completed automatically without relying on an artificial manner, and the two support bars only touch the ineffective area when the plate is transferred, and do not touch the effective area, so It can completely avoid the contamination and damage of the board, which will help the yield increase.

Another main feature of the present invention is that the support bar of the main frame has a curvature and can be spaced apart from the plate member disposed in the lower main frame by a safe distance to prevent the plate from being touched by each other. Damage or contamination.

Another object of the present invention is to provide a panel carrier for improving the heat convection effect of an oven, wherein the present invention has a non-planar structure on the top or bottom surface of at least two opposite side frames; The non-planar structure includes at least one of at least one concave portion and at least one convex portion; therefore, when a plurality of plate carriers are stacked, the four side frames of the plurality of plate carriers form an air flow passage for airflow therebetween In order to allow the heat to be transmitted laterally, the heat convection effect of the oven is enhanced, and the plate is heated on average to improve the product yield.

Referring to the fourth figure, a side view of the multi-layer stacking of the panel carrier for improving the heat convection effect of the oven of the present invention. When the plurality of main frames 10 are stacked on each other, since the support bar 20 above the main frame 10 of the upper layer has a curvature, and the support bar 20 supports the plate member 3 with a portion of the arc top, the support bar 20 at the upper side The space below is generated to have a sufficient depth to allow the lower support bar 21 to be disposed farther away from the main frame 10 located in the lower layer, and to be spaced apart from the plate member 3 disposed in the lower main frame 10. A safe distance D prevents the board 3 from being damaged or contaminated by mutual contact.

Referring to the fifth drawing, a schematic view of a preferred embodiment of the panel carrier for improving the heat convection effect of the oven of the present invention is shown. As shown in the fifth figure, the present invention is further provided with at least two support bars 20, 21 which are arranged in a cross arrangement and span the hollow region 13 to support the plate member 3, wherein the at least The position of the two support bars 20, 21 must correspond to the ineffective area 31 of the panel 3. Preferably, at least one of the at least two support bars 20, 21 has a curvature, such as the support bar 20 located above, or the at least two support bars 20, 21 have a curvature. Thereby, the support strip 20 having a curvature can support the panel 3 with a portion of the arc top.

Referring to the sixth drawing, a schematic view of another preferred embodiment of the panel carrier for improving the heat convection effect of the oven of the present invention is shown. When the structure described above enters the oven for baking process, since the top surface and the bottom surface of the four-sided frame 11 have a planar structure, when the plurality of plate carriers 1 are stacked, the four-sided frame of the plurality of plate carriers 1 11 overlapping each other without leaving a gap, in fact, a plurality of panel carriers 1 are in a stacked state, such as a gap that does not have sufficient space when the four side frames 11 are fitted to each other, and the stacked four-sided frame will constitute a four-sided wall. Therefore, the hot air of the oven is blocked by the four walls, and the heat energy cannot be transmitted laterally, which causes the heat convection effect of the oven to be lowered, so that the plate 3 is unevenly heated.

Therefore, the present invention has a non-planar structure 15 on the top or bottom surface of at least two opposite side frames; that is, the two sides of the short side of the four side frame 11 and the two sides of the long side of the four side frame 11 11 or the top or bottom surface of the long and short sides of the four-sided frame 11 may respectively form the non-planar junction Structure 15.
