Abstract

The present invention relates to the field of diode processing technology, and in particular to a diode processing glue coating device, comprising a workbench and a guide frame fixed to the inner side of the workbench, a collection frame slidably connected to the guide frame, a shell fixed to the workbench, and electric doors rotatably installed on both sides of the shell. The present invention uses a vacuum pump to evacuate the shell so that the shell is in a vacuum environment. At the same time, the vacuum pump also evacuates the storage barrel through an air guide pipe and an air extraction pipe so that the glue in the storage barrel is in a vacuum state. The electric stirring frame is started to stir the glue in the storage barrel so that the bubbles in the glue are eliminated. The glue after the bubbles are eliminated is then sprayed out through a nozzle to vacuum-coat the diode. In this way, the glue can be vacuum-treated and then vacuum-coated on the diode, preventing the generation of bubbles, thereby improving the quality of glue coating.

Description

Technical Field

[0001] The present invention relates to the technical field of diode processing, and in particular to a diode processing glue coating device. Background Art

[0002] During the processing of diodes, the gluing step is intended to evenly coat the surface of the tube core after pickling and high-temperature drying with a layer of silicone rubber. This layer of silicone rubber can isolate the PN junction of the tube core from the external environment, preventing the influence of surrounding impurities on device performance, thereby protecting the tube core and stabilizing its surface.

[0003] The Chinese patent with announcement number CN114985199B discloses a gluing device for the production of high-voltage ultra-fast recovery diodes. The machine is slidably connected to the diode mounting part through guide cavities on both sides. The diode mounting part is provided with a plurality of synchronously rotating clamping parts, and the clamping parts are used to clamp the diode. Among them, a gluing part for gluing the diode is set at one end of the table of the machine, and a drying part for drying the diode after gluing is set at the other end of the table of the machine. The diode mounting part can slide and switch between the gluing part and the drying part. Although the above patent can apply glue to the surface of the diode, the gluing process is not carried out in a vacuum environment, resulting in the inability to effectively remove the fine bubbles in the glue. When the glue containing bubbles is applied to the surface of the diode, the bubbles expand or burst during the curing process, which is likely to form surface defects, reduce the aesthetics of the product, and affect the quality of the gluing. In addition, due to the lack of vacuum processing capacity for the glue storage container, the glue is prone to secondary bubbling when it is left standing for a long time or under temperature changes, further aggravating the gluing quality problem.

[0004] The present invention aims to solve the problems existing in the above patents. To this end, a diode processing and gluing device is proposed, which can vacuum-coat the diode after the glue is vacuum-treated, prevent the generation of bubbles, and improve the gluing quality.

The front and rear electric slides 144 are symmetrically installed on the side close to each other with a driving motor 149, and the output shaft end of the driving motor 149 is fixedly connected to the inner end of the driving rod 147.

[0035] Initially, the feed pipe 7 is connected to a container filled with glue, and the glue is first discharged into the feed pipe 7, and the glue in the feed pipe 7 is discharged into the storage barrel 61, and the glue contacts the electric stirring frame 131. The electric control valve 71 blocks the glue in the storage barrel 61. When the storage barrel 61 is filled with an appropriate amount of glue, the glue is stopped from being discharged into the hose 155, and an appropriate amount of diodes are placed on the loading rack 146. Then, the left and right electric doors 4 are started to swing downward and open, and the electric doors 4 swing downward to drive the guide rail III 143 to swing downward to a horizontal state, and then the right drive motor 149 is started, and the right drive motor 149 drives the right drive rod 147 to swing upward, and the right drive rod 147 swings upward through the straight hole 148 to drive the loading rack 146 to move upward, and the loading rack 14 6 drives the diode to move upward. When the loading rack 146 moves upward to the maximum stroke, the right drive motor 149 is turned off, and the right electric slide 144 is started to move to the left. The right electric slide 144 moves to the left and drives the loading rack 146 to move to the left through the drive rod 147. The loading rack 146 drives the diode to move to the left. The right electric slide 144 continuously moves to the left and slides on the guide rails III 143 and II 142, thereby causing the loading rack 146 to drive the diode to move to the left and be in the housing 3. When the diode moves to the left and is located just above the electric rotating seat 81, the right electric slide 144 is turned off. At this time, the right electric slide 144 is on the guide rail II 142, and then the right drive motor 149 is started to rotate in the opposite direction. The right drive motor 14 9 reverse rotation drives the right driving rod 147 to swing downward, and the right driving rod 147 drives the right loading rack 146 to move downward through the slotted hole 148. The right loading rack 146 moves downward to drive the diode to move downward. The diode moves downward to the electric rotating seat 81 and contacts the reed 82. The diode stops moving downward. The loading rack 146 continues to move downward so that the inner top contacts the diode. The loading rack 146 moves downward to push the diode to move downward and squeeze the reed 82. When the diode moves downward to the inner center position of the electric rotating seat 81, the right driving motor 149 is turned off, the loading rack 146 stops moving downward, and the reed 82 clamps the diode. The right electric slide 144 can be started to pass through the guide rail II 142 and the guide rail III 14 3 moves to the right to reset, the right electric slide 144 moves to the right and drives the loading rack 146 to move to the right to reset through the driving rod 147, the loading rack 146 moves to the right to reset and disengages from the diode, the right electric slide 144 is closed, the left and right electric doors 4 are started to swing upward to reset and close the shell 3, the electric doors 4 drive the left and right guide rails III 143 to swing upward to reset, now the nozzle 6 is just above the rightmost diode, first start the vacuum pump 9, the vacuum pump 9 vacuums the shell 3, and at the same time starts the control valve I 101, the control valve I 101 stops closing the inside of the air guide pipe 10, the vacuum pump 9 vacuums the exhaust pipe 11 through the air guide pipe 10, the exhaust pipe 11 vacuums the storage barrel 61, and now start the electric stirring rack 131,The electric stirring frame 131 stirs the glue, and the bubbles in the glue after stirring are eliminated in the vacuum environment of the storage barrel 61. When the bubbles in the glue in the storage barrel 61 are completely eliminated, the electric stirring frame 131 and the control valve I101 are closed, and the vacuum pump 9 is closed at the same time, and the electric control valve 71 can be started. The glue in the storage barrel 61 is discharged into the nozzle 6 through the electric control valve 71, and then the biaxial moving machine 5 is started to drive the nozzle 6 to move downward. The nozzle 6 moves downward and is close to the rightmost diode in the coating area. The biaxial moving machine 5 is closed, and the nozzle 6 is started to spray the glue on the diode in a vacuum environment to complete the vacuum coating. At the same time, the electric rotating seat 81 is started to rotate. The rotation of the electric rotating seat 81 drives the reed 82 to rotate, and the rotation of the reed 82 drives the diode to rotate. The glue is fully coated on the rotation, and the glue forms a layer of silicone rubber on the surface of the diode. In this way, the diode can be vacuum coated after the glue is vacuum treated to prevent the generation of bubbles, thereby improving the quality of glue coating. When the rightmost diode is coated with glue, the nozzle 6 and the electric control valve 71 are closed, the nozzle 6 stops spraying glue, and the storage barrel 61 stops discharging glue into the nozzle 6. The electric rotating seat 81 is closed, and the electric rotating seat 81 stops driving the rightmost diode to rotate through the reed 82. Then the dual-axis moving machine 5 is started to drive the nozzle 6 to move upward and reset. The dual-axis moving machine 5 is controlled to drive the nozzle 6 to move to the left to correspond to the next diode. The nozzle 6 moves to the left, driving the storage barrel 61 to move to the left, and the storage barrel 61 moves to the left to drive the exhaust pipe 11 And the feed pipe 7 moves to the left, the hook 13 supports and guides the exhaust pipe 11 and the feed pipe 7 moving to the left, so as to prevent the exhaust pipe 11 and the feed pipe 7 from being scattered and knotted, affecting their use. Then, the glue can be vacuum-coated on the diode according to the above operation. During the coating process, excess glue falls downward through the opening of the workbench 1 and falls into the guide frame 2. The glue in the guide frame 2 flows into the collecting frame 21 for collection. At the same time, while the diodes are being coated with glue, the operator can continue to place an appropriate amount of diodes on the loading rack 146. After the diodes on the electric rotating seat 81 are coated with glue, the nozzle 6 is driven to move upward and reset by the dual-axis moving machine 5, and the nozzle 6 is driven to move right and reset. The nozzle 6 passes through the storage The cylinder 61 drives the feeding pipe 7 and the exhaust pipe 11 to move to the right and reset, and the hook 13 continues to support and guide the feeding pipe 7 and the exhaust pipe 11 during the reset process, and then the left and right electric doors 4 are started to swing downward, driving the left and right guide rails III 143 to swing downward to a horizontal state, and then the left electric slide 144 is started to move to the right, and the left electric slide 144 moves to the right and drives the unloading rack 145 to move to the right through the left driving rod 147, and the left electric slide 144 moves to the right and slides onto the guide rail III 143 onto the guide rail II 142, and then the unloading rack 145 moves to the right into the shell 3 and is directly under the diode coated with glue, and then the left electric slide 144 is closed, and the left driving motor 149 is started to drive the left driving rod 147 to swing upward,The left driving rod 147 swings upward to drive the unloading rack 145 to move upward, and the unloading rack 145 moves upward to contact the diode, and the unloading rack 145 moves upward to drive the diode to move upward, and the diode moves upward to break contact with the reed 82 to complete the unloading, and the left driving motor 149 is turned off. The left driving rod 147 stops driving the diode to move upward, and the left electric slide 144 is started to move to the left and reset. The unloading rack 145 is driven to move to the left and reset by the left driving rod 147. The unloading rack 145 resets and drives the diode to move to the left to the outside of the shell 3, and the left electric slide is turned off. The unloading rack 145 and the loading rack 146 can complete the loading and unloading of the diodes, thereby improving the overall work efficiency. At this time, the right electric slide 144 is started to move to the left, so that the next batch of diodes moves to the left to the shell 3 to complete the subsequent loading. After the next diode is loaded, the electric door 4 is started to swing upward and closed, and the vacuum pump 9 can be started again to make the shell 3 vacuum state. According to the above operation, the diodes can continue to be coated with glue. At the same time, the operator can remove the glue-coated diodes from the unloading rack 145. When the collection frame 21 is filled with an appropriate amount of glue, pull the collection frame 21 to the left to disengage it from the guide frame 2, and perform subsequent processing on the glue in the collection frame 21. When all the glue in the collection frame 21 is poured out, the collection frame 21 is returned to the guide frame 2.

[0036] See also Figure 10 and Figure 11 As shown, the diode processing glue coating device also includes an electric manipulator 15, a frame 151, a heating wire 152, a discharge pipe 153, a control valve II 154 and a water supply component. The electric manipulator 15 is symmetrically installed on the front and rear sides of the right side of the shell 3. A frame 151 is installed between the tail ends of the front and rear electric manipulators 15. The frame 151 can collect the removed residual glue. The upper part of the outer surface of the frame 151 is installed with a heating wire 152. When the heating wire 152 is started, the heating wire 152 can heat the nozzle 6 to melt and remove the residual glue attached to the nozzle 6. A discharge pipe 153 is connected between the front side of the frame 151 and the right side of the front side of the shell 3. The front side of the discharge pipe 153 is installed with a control valve II 154. The shell 3 A water supply assembly is provided between the shell 3 and the nozzle 6. When the water supply assembly is in operation, the water supply assembly can discharge water into the nozzle 6 to clean the nozzle 6. The water supply assembly includes a hose 155, a control valve III 1551, a cross frame 156 and a guide frame 157. The hose 155 is fixedly connected to the upper rear side of the right side of the shell 3. The water outlet end of the hose 155 is connected to the lower rear side of the nozzle 6. The hose 155 can discharge water into the nozzle 6. The control valve III 1551 is installed at the lower part of the hose 155. A cross frame 156 is fixed to the top rear side of the shell 3. Four guide frames 157 are slidably connected to the bottom of the cross frame 156. The inner side of the guide frame 157 is in contact with the hose 155. The guide frame 157 can support and limit the hose 155.

[0037] Initially, the hose 155 is connected to an external water source. When water is first discharged into the hose 155, the water in the hose 155 is blocked by the control valve III 1551. When the nozzle 6 moves to the left, the nozzle 6 drives the hose 155 to move to the left, and the hose 155 drives the guide frame 157 to move to the left. The guide frame 157 supports and guides the hose 155 moving to the left. After all the diodes are coated with glue, the electric manipulator 15 is started to drive the frame 151 to move, and the frame 151 drives the heating wire 152 to move. Then, when the frame 151 moves and covers the lower part of the nozzle 6, the electric manipulator 15 is closed and the heating wire 152 is started. The heating wire 152 contacts the nozzle through the frame 151. 6 is heated, and the residual glue attached to the nozzle 6 melts under the high temperature environment. The melted residual glue falls from the nozzle 6 into the frame 151, and the control valve III 1551 is started at the same time. The control valve III 1551 stops blocking the water in the hose 155, and the water in the hose 155 is discharged into the nozzle 6. The water flushes the melted residual glue in the hose 155, and the water and the residual glue fall into the frame 151 together. The water in the frame 151 is discharged into the discharge pipe 153 together with the residual glue and is blocked by the control valve II 154. The control valve II 154 is started, and the control valve II 154 stops blocking the water and residual glue in the discharge pipe 153. The discharge pipe 153 discharges the water and the residual glue for collection and treatment. When all the residual glue inside the nozzle 6 is removed, the heating wire 152 and the control valve III 1551 are closed, the water in the hose 155 stops flowing into the nozzle 6, and the control valve II 154 is closed at the same time. Then, the electric mechanical arm 15 is activated to drive the frame 151 to move to its original position. The frame 151 stops covering the lower part of the nozzle 6. Then, when the nozzle 6 moves to the right and resets, the nozzle 6 drives the hose 155 to move to the right and resets, and the guide frame 157 continues to support and guide the hose 155. This prevents the large amount of glue remaining in the nozzle 6 from solidifying and causing blockage, so that the nozzle 6 can be used normally in the future.

[0038] See also Figure 1 As shown, the diode processing and gluing device further includes a transparent window 16 , which is fixedly connected to the upper left side of the housing 3 , and the transparent window 16 allows an operator to check the gluing status of the diode.

[0039] When the diode is being coated with glue, the operator can check the gluing situation of the diode through the transparent window 16. Like this, can make corresponding processing according to the gluing situation of the diode in time, thereby guarantee the smooth gluing of the diode.
