Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

MOS pipe components and parts that high generate heat are often used at vehicle power supply product, and the design process often is the laminating and dispels the heat on high heat conduction aluminum product. However, in order to achieve good heat dissipation and insulation effects between the MOS transistor device and the aluminum material, a heat-conducting silicone grease/heat-conducting gel is commonly added between the MOS transistor device and the aluminum material to be used in cooperation with the ceramic wafer; however, in practical production, uniform coating of the heat-conducting silicone grease/heat-conducting gel on the surface of the ceramic wafer becomes a great difficulty, and the traditional manual coating of the ceramic wafer has low efficiency and is not uniform and incomplete.

Therefore, the present application provides a duplex printing apparatus 100, which can greatly improve the painting efficiency on the premise of ensuring the painting uniformity, as shown in fig. 1 and 2, the duplex printing apparatus 100 includes a first printing plate 10, a second printing plate 20 and a base 30. A rotating shaft 40 is provided in the middle of the base 30, and the first printed board 10 and the second printed board 20 are symmetrically pivoted to the rotating shaft 40 and can rotate around the rotating shaft 40. In the rest state, as shown in FIG. 1, first printing plate 10 and second printing plate 20 are symmetrically laid on base 30. When the first printed board 10 and the second printed board 20 are rotationally attached, the faces attached to each other are the first plate face 12 belonging to the first printed board 10 and the second plate face 22 belonging to the second printed board 20, respectively. As shown in fig. 2, the first board surface 12 is partially recessed to form a first recessed groove 14, and the second board surface 22 is symmetrically recessed to form a second recessed groove. As shown in fig. 2 to 4, the first concave groove 14 and the second concave groove are used for containing the to-be-printed part 200, and when the first printing plate 10 and the second printing plate 20 are rotatably attached, the first placing groove 14 and the second placing groove form a containing space for containing the to-be-printed part 200. Parts of the first and

second groove bottoms

142, 242 of the first and

second placement grooves

14, 242 are replaced by the ladder steel net 50, that is, parts of the first and

second groove bottoms

142, 242 are replaced by the ladder steel net 50, and these replaced parts are areas for applying the printing liquid later. When the first printing plate 10 and the second printing plate 20 are rotatably attached to each other, the to-be-printed part 200 is clamped by the ladder steel mesh 50 respectively disposed on the first groove bottom 142 and the second groove bottom 242, and at this time, the printing liquid is uniformly coated in the meshes of the ladder steel mesh 50, so that the two clamped surfaces of the to-be-printed part 200 can be uniformly coated with the printing liquid. In specific practical operation, when two surfaces of the part to be printed 200 need to be coated, only the first printing plate 10 and the second printing plate 20 which are attached to each other need to rotate around the rotating shaft 40 to expose the mesh surfaces to be coated, that is, only one clamping is needed, double-sided coating of the part to be printed 200 can be achieved, and printing liquid efficiency is improved. It should be noted that the to-be-printed part 200 in the embodiment may be the above-mentioned ceramic sheet, or may be other components that need to be coated, and the printing liquid for coating the to-be-printed part 200 is not limited to the heat-conductive silicone grease or the heat-conductive gel, and may be applied as long as the electric glue has a good heat-conductive effect.

In one particular embodiment, as shown in fig. 2, the first slot bottom surface 144 of the first placement slot 14 and the second slot bottom surface 244 of the second placement slot are coplanar with the first mesh surface of the ladder steel mesh 50 that is conformably opposed. The first and

second placement grooves

14 and 14 are used for containing the part 200 to be printed (not shown in fig. 2), and when the two are fastened together to allow the ladder steel net 50 to clamp the part 200 to be printed, the clamping area of the ladder steel net 50 is the area where the part 200 to be printed is printed. In order to ensure that the clamping area is the entire ladder steel mesh 50, the first mesh surface of the ladder steel mesh 50 must be coplanar with the first and second

groove bottom surfaces

144 and 244, if the first mesh surface is lower than the first and second

groove bottom surfaces

144 and 244, the part 200 to be printed is clamped by the first and second

groove bottom surfaces

144 and 244, and at this time, the coating of the printing solution is severely uneven, and if the first mesh surface is higher than the first and second

groove bottom surfaces

144 and 244, the bottom of the part 200 to be printed in the groove is not attached to the groove bottom surface, and when the part is rotatably attached, the attachment force is transmitted to the connection part of the ladder steel mesh 50 and the first and

second groove bottoms

142 and 242, and the breakage of the ladder steel mesh 50 and the first and second

groove bottom surfaces

144 and 244 occurs when the force is too large.

In a specific embodiment, as shown in fig. 1 and 2, the number of the first placing grooves 14 and the second placing grooves is plural, and the plurality of placing grooves can ensure that a plurality of parts to be printed 200 (not shown in the figure) can be placed at one time, so that the parts to be printed 200 can be coated with the printing solution at one time, and the printing efficiency is greatly improved. Preferably, a plurality of standing grooves can be in array distribution to effectively utilize face space.

In one specific embodiment, as shown in FIGS. 2 and 5, the surface of first printing plate 10 opposite second printing plate 20 is third plate surface 16, a portion of the area of third plate surface 16 is recessed to form first scraping trough 18, the surface of second printing plate 20 opposite first printing plate 10 is fourth plate surface 26, and a portion of the area of fourth plate surface 26 is recessed to form second scraping trough 28. After the coating process of the printing liquid is completed, the excessive printing liquid is attached to the mesh surface of the ladder steel mesh 50, and if the printing liquid is not disposed in time, the printing liquid is attached to the mesh surface all the time, so that the effect of the next coating is affected. Therefore, in order that the subsequent ladder steel net 50 is not affected by the surplus of the previous printing liquid, the first scraping groove 18 and the second scraping groove 28 are specially arranged, and after the coating process is completed, the surplus of the printing liquid can be removed only by scraping along the first scraping groove surface 184 and the second scraping groove surface 284.

In one particular embodiment, as shown in fig. 2 and 5, the first scraping surface 184 of the first scraping groove 18 and the second scraping surface 284 of the second scraping groove 28 are coplanar with the second, opposite, mesh surface of the ladder steel mesh 50. Since the scraping material is used for scraping the excess material on the second web surface, if the second web surface is lower than the first scraping groove surface 184 and the second scraping groove surface 284, the scraping blade is limited by the first scraping groove surface 184 and the second scraping groove surface 284, which is inconvenient to scrape, and if the second web surface is higher than the first scraping groove surface 184 and the second scraping groove surface 284, the scraping force can only attach to the second web surface, which can generate stress on the joints between the ladder steel mesh 50 and the first and

second printing plates

10 and 20, and even cause cracking.

In a particular embodiment, as shown in fig. 2 and 5, the projection of the first scraping trough 18 onto the first board 12 overlaps the projection of the first placing trough 14 onto the first board 12, and the projection of the second scraping trough 28 onto the second board overlaps the projection of the second placing trough onto the second board. As mentioned above, in order to allow a plurality of parts to be printed to be coated at the same time, a plurality of placement grooves may be provided on one printing plate, but in order to simplify the wiping process, it is preferable to provide one wiping groove on one printing plate in order to ensure that both the plurality of placement grooves and the one wiping groove can correspond to the ladder steel net 50. Therefore, the projection of the scraping groove on the board surface covers the projection of the placing groove on the board surface.

In a specific embodiment, as shown in fig. 5, the area of the base 30 corresponding to the second scraping groove 28 is provided with an overflow groove 32 to prevent the printing liquid from overflowing, and symmetrically, the area of the base 30 corresponding to the first scraping groove is also provided with the overflow groove 32. When the part to be printed is clamped and rotated by the ladder steel mesh 50, a part of the printing liquid overflows due to excessive coating, and in order to prevent the printing liquid from overflowing out of the base 30, the glue overflow groove 32 can be arranged on the base 30 to prevent the printing liquid from overflowing.

In a specific embodiment, as shown in FIG. 1, a conformable assembly 60 is disposed on the first printing plate 10 and the second printing plate 20, such that when the first printing plate 10 and the second printing plate 20 rotate, a snug fit is achieved by the conformable assembly 60. The rotatable first printing plate 10 and the rotatable second printing plate 20 are tightly attached together by the attaching assembly 60, thereby achieving a tight clamping of the step steel plate 50 to the part to be printed 200. Specifically, the attaching assembly 60 includes paired magnetic units symmetrically distributed on the first board 12 and the second board 22, and when the first printed board 10 and the second printed board 20 rotate, the magnetic units (attaching assembly 60) are closely attached to each other. The two plate surfaces are provided with a plurality of groups of symmetrically distributed magnetic units, and the rotatable first printing plate 10 and the rotatable second printing plate 20 are tightly attached together through the magnetic units, so that the step steel plate 50 is tightly clamped on the part 200 to be printed.

In a specific embodiment, as shown in fig. 1, pivoting handles 70 are provided on the first printing plate 10 and the second printing plate 20, respectively, and the pivoting handles 70 are provided to facilitate pivoting engagement of the first printing plate 10 and the second printing plate 20.
