Description

Technical Field

[0001] The utility model relates to the technical field of screen printing ovens, and particularly relates to a vertical placement structure for screen printing ovens. Background Art

[0002] A solar screen printing plate is a template used for solar cell printing, generally including a screen frame and a screen cloth, and the screen frame and the screen cloth are connected through a hot melt adhesive film. The main manufacturing process of the solar screen printing plate is: stretching the screen - coating - exposure - development. Among them, coating is to evenly brush the photosensitive emulsion on the surface of the screen cloth. After coating, the solar screen printing plate needs to be placed in an oven to evaporate the moisture contained in the photosensitive emulsion.

[0003] Among them, the publication number CN218565920U discloses a solar screen printing oven structure, which includes an oven and a placement rack. The placement rack includes a plurality of horizontally arranged square tubes and vertically arranged columns. The placement rack further includes a plurality of limiting members arranged along the horizontal direction. The plurality of limiting members are used for storing solar screen printing plates. The two ends of each limiting member are respectively fixed between the tops of two square tubes at the same height, and the plurality of limiting members are evenly distributed at intervals along the length direction of the square tubes. A limiting column is fixed vertically between adjacent two limiting members, and the bottom of the limiting column is fixed on the top of the square tube. The purpose of this application is to provide an oven structure that can dry multiple solar screen printing plates simultaneously, thereby effectively improving the drying efficiency of solar screen printing plates.

[0004] This device places multiple groups of screen printing plates on the upper side of the placement rack, and then places the placement rack inside the oven for drying the screen printing plates. However, since the placement rack places a relatively large number of screen printing plates at one time, the weight of the placement rack is relatively large, making it inconvenient to move the placement rack into the oven and requiring multiple people to carry it, resulting in a more cumbersome loading and unloading process and reducing the drying efficiency of the screen printing plates.

[0005] Therefore, it is very necessary to invent a vertical placement structure for screen printing ovens to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a vertical placement structure for screen printing ovens to solve the problem in the technology that since the placement rack places a relatively large number of screen printing plates at one time, the weight of the placement rack is relatively large, making it inconvenient to move the placement rack into the oven and requiring multiple people to carry it, resulting in a more cumbersome loading and unloading process and reducing the drying efficiency of the screen printing plates.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical placement structure of a screen oven, comprising an oven body, a guide groove is provided at the bottom of the oven body, a guide plate is rotatably connected to the front side of the guide groove, a placement rack is arranged inside the oven body, a support bottom plate is fixedly connected to the lower end of the placement rack, four groups of positioning rollers are rotatably connected to the lower surface of the support bottom plate, three groups of vertically distributed support cross bars are fixedly connected to the inner side of the placement rack, and multiple groups of discharge structures are arranged between the upper and lower groups of the support cross bars, and the discharge structure comprises a first positioning rack, a positioning protrusion, a positioning shell, a positioning spring, a second positioning rack and a positioning shaft.

[0008] By adopting the above technical solution, during the loading process, multiple groups of screens are placed between multiple groups of first positioning frames and second positioning frames respectively, and then the guide plate is rotated downward, and then the multiple groups of discharge structures are pushed to the inside of the oven body by using the positioning roller.

[0013] By adopting the above technical solution, the discharge structures on the upper and lower sides are poorly distributed, thereby preventing the liquid on the surface of the upper screen from dripping onto the surface of the lower screen.

[0014] Optionally, multiple groups of through holes are formed on the left and right side surfaces of the first positioning frame, the positioning protrusion is slidably connected to the through holes, the positioning protrusion is located on one side of the first positioning frame in an arc shape, a positioning rod is fixedly connected to the side of the positioning protrusion, and the end of the positioning rod facing away from the positioning protrusion is fixedly connected to a limiting block.

[0015] By adopting the above technical solution, the positioning protrusion slides left and right inside the through hole.

[0016] Optionally, the positioning housing is fixedly connected to the positions on the left and right sides of the first positioning frame located outside the through hole. A first positioning groove is provided in the middle of the positioning housing. Limiting grooves are provided on the inner walls of the front and rear sides of the first positioning groove.

The two ends of the positioning spring are respectively abutted against the side wall of the positioning convex block and the inner wall of the second positioning groove.

[0019] By adopting the above technical solution, the positioning spring pushes the positioning convex block outward, and the two groups of positioning convex blocks cooperate to clamp and fix the inner screen plate.

[0020] Optionally, a plurality of positioning shafts are rotatably connected to the inner side of the second positioning frame.

[0021] By adopting the above technical solution, the positioning shaft is used to support the screen plate.

[0022] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0023] 1. By rotating the guide plate downward, and then using the positioning roller to push a plurality of feeding structures into the oven body. At this time, the positioning roller is stuck inside the guide groove to position the positioning roller. At the same time, the front guide plate is turned upward to position the front side of the support bottom plate to prevent it from shaking. It realizes the beneficial effect of facilitating the pushing of the placement rack carrying the screen plate into the oven body, further improving the feeding efficiency of the screen plate, thereby improving the drying efficiency of the screen plate, and improving the stability of the placement rack, and solves the problem that because the placement rack places a large number of screen plates at one time, the weight of the placement rack is large, it is inconvenient to move the placement rack into the oven, and multiple people are needed to carry it, resulting in a more cumbersome loading and unloading process and reducing the drying efficiency of the screen plate;

[0024] 2. By arranging a plurality of feeding structures inside the placement rack, the positioning springs in the feeding structures push the two positioning convex blocks inward at the same time, so that the multiple groups of positioning convex blocks on both sides clamp and fix the upper end of the screen plate, improving the stability of the screen plate during movement and drying, preventing the screen plate from being knocked, and at the same time improving the permeability around the screen plate, further improving the drying efficiency.

Three vertically distributed support cross bars 23 are fixedly connected to the inner side of the placement rack 2. Multiple groups of material discharging structures are arranged between the upper and lower support cross bars 23.

[0034] During the feeding process, the screen printing stencils are sequentially placed inside multiple sets of material feeding structures, and then multiple sets of screen printing stencils are fixed inside the placing rack 2. At this time, the guiding plate 14 is rotated outward, and then the positioning roller 22 is pushed from the surface of the guiding plate 14 into the interior of the oven body 1. At this time, the positioning roller 22 is stuck inside the guiding groove 13, and then the guiding plate 14 is rotated inward to a vertical state to clamp the front end of the placing rack 2, facilitating the movement of the placing rack 2 into the interior of the oven body 1 and improving the stability of the placing rack 2 during the drying process.

[0035] Refer to Figures 3 to 5 , the material feeding structure includes a first positioning frame 3, a positioning bump 31, a positioning shell 32, a positioning spring 38, a second positioning frame 4, and a positioning shaft 41.
