Description

Technical Field

[0001] This utility model relates to the technical field of coating equipment for diode production, specifically a diode coating device. Background Technology

[0002] A diode is a two-electrode electronic component with asymmetric conductance. An ideal diode has zero resistance between the two electrodes when it is forward-biased, but infinite resistance when it is reverse-biased. That is, current is only allowed to flow through the diode in one direction. Therefore, the diode has the characteristic of unidirectional conduction and can play a rectification role.

[0003] Application number CN202420501297.9 discloses a coating apparatus for diode production, comprising a main body, a second leg fixed to the upper end of the main body by bolts, a conveying device fixed between the second leg by bolts, a second fixing post fixed to the upper end of the conveying device by bolts, a limit block fixed to the second fixing post via a rotating shaft, and a first fixing post disposed on one side of the second fixing post, the first fixing post being fixed to the limit block via a rotating shaft. This apparatus, by setting multiple limit blocks, limits the diode during coating, preventing the diode from shifting during the coating process and causing unqualified coating of the product.

[0004] The drying chamber is located above the limiting blocks to dry the colloid on the internal diodes. However, since the drying chamber is fixed while the limiting blocks are spaced apart, the drying chamber may fail to dry the diodes inside the limiting blocks when the conveyor moves two adjacent limiting blocks, resulting in a waste of resources.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a diode coating device, including a conveyor belt 1, a storage assembly 2, a coating device 3, and a drying assembly 4. Multiple storage assemblies 2 are evenly installed on the conveyor belt 1. The coating device 3 and the drying assembly 4 are installed on the conveyor belt 1. Each storage assembly 2 includes a limiting block 21 and a groove 22, with the groove 22 formed on the limiting block 21. Multiple limiting blocks 21 are evenly distributed on the conveyor belt 1. The drying assembly 4 includes a bracket 41, a cover 42, a base plate 47, and a heating element 48. The bracket 41 is fixedly installed on the conveyor belt 1. The cover 42 is vertically slidably connected between the bracket 41 and the conveyor belt 1. The heating tube 48 is fixedly installed on the top wall of the inner cavity of the cover 42. The two base plates 47 are symmetrically and elastically rotatably connected to the inside of the cover 42. The length and width of the projection of the cover 42 on the horizontal plane are both greater than the length and width of the projection of the limiting block 21 on the horizontal plane. The storage component 2 also includes a fixing leg 23. The fixing leg 23 is rotatably connected to the side of the limiting block 21, and the bottom of the fixing leg 23 is fixedly installed on the belt of the conveyor belt 1.

[0025] Please see Figures 1 to 3 The groove 22 is precisely machined according to the size of the diode to accommodate the diode and prevent it from moving or tipping over. The glue applicator 3 is located on one side of the conveyor belt and usually uses a dispensing valve or spray system to precisely apply glue to the passing diode. The amount of glue applied can be controlled by the regulating valve to ensure uniform coverage of the glue. The heating tube 48 is fixed to the top wall of the inner cavity of the cover 42 and uses heat-resistant materials such as nickel-chromium alloy to quickly generate high-temperature hot air to cure the glue. The two base plates 47 are symmetrically and elastically rotated inside the cover 42 to realize automatic opening and closing. When the cover 42 descends, the base plate 47 contacts the limiting block 21 and rotates to form a sealed drying space. The projection size of the cover 42 on the horizontal plane is larger than that of the limiting block to ensure complete coverage and avoid heat leakage.

[0026] The drying assembly 4 also includes a duct 46 and a fan 49. The side of the cover 42 is fixedly connected to the right duct 46, and the fan 49 is installed on the inner wall of the duct 46.

[0027] Please see Figure 3 and Figure 4 When the cover 42 is in the upper position, it means that the cover 42 does not dry the colloid on the diode inside the limit block 21, but the heating tube 48 is always in working state. At this time, heat is continuously generated inside the cover 42. In this embodiment, the heat can be transported to the pipe 46 by the fan 49 and transported to the outside through the pipe 46 so that the heat can be used in other processes or equipment, thereby avoiding waste of resources.

[0028] A rotating shaft 6 is fixedly installed on the side of the base plate 47. The base plate 47 is rotatably connected to the inner wall of the cover 42 through the rotating shaft 6. A torsion spring 7 is fixedly installed between the cover 42 and the base plate 47. The torsion spring 7 is sleeved on the surface of the rotating shaft 6.

[0029] Please see Figure 5 When the cover 42 descends to cover the limiting block 21, the bottom plate 47 contacts the limiting block 21 and rotates outward under pressure to open, and the torsion spring 7 is compressed; when the cover 42 is raised, the elastic force of the torsion spring 7 causes the bottom plate 47 to automatically return to its original position, closing the bottom of the cover 42 and forming a seal. This design ensures the airtightness of the drying process, prevents heat loss, and improves thermal efficiency.

[0030] A limiting component 5 is connected between the base plate 47 and the cover 42. The limiting component 5 includes a limiting plate 51, a swing arm 52 and a connecting plate 54. One end of the swing arm 52 is fixedly connected to the rotating shaft 6, and the other end of the swing arm 52 is fixedly connected to the connecting plate 54. One end of the limiting plate 51 is fixedly installed on the connecting plate 54. The closest distance between the two limiting plates 51 is the same as the farthest distance between the two fixed legs 23.

[0031] Please see Figures 3 to 5When the base plate 47 rotates, it can drive the swing arm 52 to rotate synchronously through the rotating shaft 6. The swing arm 52 then drives the two limiting plates 51 to rotate simultaneously through the connecting plate 54, so that the two limiting plates 51 are attached to the outer side wall of the two fixed legs 23, thereby positioning the limiting block 21 through the fixed legs 23.

[0032] The limiting component 5 also includes a stop 53, which is fixedly installed on the surface of the base plate 47, and the bottom surface of the stop 53 is in contact with the surface of the swing arm 52.

[0033] Please see Figure 3 The stop block 53 is designed to block the swing arm 52 under normal circumstances, so as to prevent the swing arm 52 from rotating excessively and causing the base plate 47 to open downward.

[0034] The drying assembly 4 also includes a cylinder 43, a limiting rod 44, and a connecting arm 45. The cylinder 43 is fixedly mounted on the bracket 41, and the output end of the cylinder 43 is fixedly connected to the top of the cover 42. The limiting rod 44 is vertically fixedly mounted on the bracket 41. One end of the connecting arm 45 is fixedly mounted on the cover 42, and the other end of the connecting arm 45 is slidably connected to the limiting rod 44.

[0035] Please see Figure 2 The cylinder 43 is fixedly mounted on the bracket 41 and is pneumatically or hydraulically driven. Its output end is directly connected to the top of the cover and is controlled by a solenoid valve to extend and retract, driving the cover 42 to move up and down. The limit rod 44 is vertically fixedly mounted on the bracket 41 as a guide mechanism to ensure that the cover 42 remains vertical when it moves, preventing tilting or jamming. One end of the connecting arm 45 is fixed to the cover 42, and the other end is slidably connected to the limit rod 44 through a slider or bearing to bear lateral force and reduce friction.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
