Detailed Description
The present invention will be more clearly and completely described below with reference to the accompanying drawings.
Fig. 1 and 2 show a tool for assembling a carbon sheet of a collimator, which includes two oppositely disposed supports 10 and a plurality of grid sheets (not shown) between the supports 10. A frock for collimator carbon piece assembly includes: a base 100 and a bead 200. The base 100 has a receiving groove 110 on the top surface thereof, the receiving groove 110 is used for receiving a collimator, a relief hole 111 is formed at the bottom of the receiving groove 110, the grid plate is located in the relief hole 111, when the carbon plate 20 is mounted on the collimator, the carbon plate 20 is flush with the top surface of the base 100, and threaded holes (not shown) are formed in the top surface of the base 100 on both sides of the receiving groove 110. The two ends of the pressing strip 200 are provided with connecting holes 210, the pressing strip 200 crosses the accommodating groove 110, the bottom surface of the pressing strip 200 is a pressing surface 220, the pressing surface 220 can be pressed on the carbon sheet 20, and screws can pass through the connecting holes 210 and be connected to the threaded holes.
After the grid plate is installed on the support 10 and gluing and fixing are completed, the carbon plate 20 needs to be installed on the top of the grid plate, and the carbon plate 20 can be pressed by the tool at the moment, so that tilting is prevented, the flatness of the carbon plate 20 is improved, the product quality is improved, and the production cost is reduced. Firstly, a semi-finished collimator of a carbon sheet 20 to be installed is placed in the accommodating groove 110, a grid sheet is located in the avoiding hole 111, the bottom of the support 10 is attached to the bottom surface of the accommodating groove 110, the carbon sheet 20 which is coated with glue is installed to the top of the grid sheet at the moment, the protrusion of the top of the grid sheet is inserted into the matching hole in the carbon sheet 20, the pressing strip 200 is installed on the base 100 through a screw, and the pressing surface 220 is pressed on the carbon sheet 20, so that the situation that the carbon sheet 20 cannot be tilted and deformed after glue is applied to the carbon sheet 20 for solidification is guaranteed.
In this embodiment, the accommodating groove 110 is a structure with two through ends. The through containing groove 110 is more convenient for placing and taking out the collimator of the carbon sheet to be installed.
During actual machining, a chamfer is formed at the joint of the bottom of the accommodating groove 110 and the two side walls, so that the bottom of the support 10 cannot be completely attached to the bottom surface of the accommodating groove 110, the carbon sheet 20 is not parallel to the top surface of the base 100, and the flatness of the carbon sheet 20 cannot be guaranteed. As shown in fig. 3, to solve this problem, it is ensured that the bottom of the bracket 10 is attached to the bottom surface of the receiving groove 110, and an avoiding groove 112 extending along the extending direction of the receiving groove 110 is formed at the joint of the bottom of the receiving groove 110 and the two side walls.
In this embodiment, in order to ensure the flatness of the carbon sheet 20, the flatness of the bottom surface of the accommodating groove 110 is 0.02m, and the flatness of the top surface of the susceptor 100 is 0.02 m.
In this embodiment, the number of the pressing strips 200 is three, the three pressing strips 200 are arranged in parallel, and the two pressing strips 200 located at the two sides are pressed on the two ends of the carbon sheet 20. The end of the carbon sheet 20 is most easily tilted, and the pressing of the pressing strip 200 can ensure that no flash appears on the carbon sheet.
Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims.
