[0001] This invention relates to the field of electronic component processing, and more particularly to an electronic component dispensing device. Background Technology

[0002] Electronic components are mainly soldered onto printed circuit boards and interconnected to form an electronic circuit with a specific function. After the electronic components are assembled, glue needs to be applied to the surface or back of the electronic components through a dispensing device to protect the electronic components and improve product performance.

[0003] Patent application number CN202321676741.2 discloses a dispensing device for electronic component processing, including a dispensing device body, a dispensing head, a worktable, and a circuit board with electronic components. A frame is fixed to the top of the dispensing device body, and a first linear guide rail is provided on the top of the frame. A second linear guide rail is slidably connected to the first linear guide rail, and a fixing plate is slidably connected to the second linear guide rail. A dispensing head is provided on one side of the fixing plate, and a dispensing needle is provided at the center of the bottom of the dispensing head. A baffle is provided on the dispensing head outside the dispensing needle. A third linear guide rail is provided on the dispensing device body below the dispensing head, and a worktable is slidably connected to the top of the third linear guide rail. A circuit board with electronic components is placed on the worktable. The circuit board with electronic components is placed on the worktable. By rotating the adjusting screw, the limiting component can be moved down to fix the circuit board. After that, the relative position of the dispensing head and the worktable is adjusted so that the dispensing head is aligned with the dispensing position of the circuit board with electronic components. The dispensing needle is used to perform the dispensing work. However, this type of dispensing device can only meet the dispensing needs of electronic components on flat circuit boards. In order to meet the needs, more and more curved circuit boards or circuit boards with irregular shapes are being designed. This type of dispensing device cannot meet the dispensing needs of curved or irregular surfaces.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electronic component dispensing device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses an electronic component dispensing device, comprising a table with multiple feeding devices on it. Each feeding device includes a feeding screw and a feeding slide rod mounted on the table. The feeding screw is driven to rotate by a feeding motor. Each feeding screw has a slide rod threadedly connected to it. The feeding slide rod passes through the slide rod and is slidably connected to it. Each slide rod has a vertical plate fixed to it, and a rotary motor is fixed to the vertical plate. A support plate is fixed to the output end of the rotary motor. Fixed seats are provided on both sides of the support plate. A lampshade is fixed to the end of each feeding screw on the table, and ultraviolet lamps are uniformly fixed inside the lampshade. Above the table, there is also a dispensing screw and a dispensing slide rod. The dispensing screw is driven to rotate by a dispensing motor. A sliding plate threadedly connected to the dispensing screw is mounted on the dispensing screw. A lifting cylinder is fixed to the sliding plate, and a mounting plate is fixed to the piston rod end of the lifting cylinder. A glue tube is fixed to the mounting plate.

[0008] Preferably, each of the mounting bases is fixed to a corresponding mounting plate, and the mounting plate is fixed to the corresponding support plate by bolts. The mounting plate is rotated according to the different specifications of the circuit board, and both ends of the circuit board are inserted into the mounting slots on the corresponding mounting plate mounting base.

[0009] Preferably, a receiving cylinder is fixed on the slide plate below the glue tube, and a material tray is fixed to the end of the piston rod of the receiving cylinder. During glue dispensing, the receiving cylinder is activated, the piston rod on the receiving cylinder shortens, and the material tray moves away from below the dispensing needle. After glue dispensing, the dispensing needle rises, the dispensing cylinder is activated again, the piston rod on the dispensing cylinder extends, and the material tray reaches below the dispensing needle to catch the glue dripping from the dispensing needle, preventing glue from dripping onto the circuit board.

[0010] Preferably, multiple sealing cylinders are fixed on the table surface on one side of the lampshade, and a baffle is also provided on one side of the lampshade. The piston rod end of the sealing cylinder is fixed to the corresponding baffle. When the UV adhesive cures, the sealing cylinder is activated, the piston rod on the sealing cylinder shortens, and the baffle descends, blocking the ultraviolet lamp through the baffle to avoid light pollution.

[0011] Compared with existing technologies, the present invention has the following advantages:

[0012] This device fixes irregularly shaped circuit boards to a support plate, and drives the support plate to rotate via a rotary motor, rotating the circuit board at the electronic component mounting position to a horizontal state. Adhesive is then applied to the electronic components, preventing the adhesive from slipping. After adhesive is applied to one electronic component position, it is cured by ultraviolet light. Once cured, adhesive is applied to another electronic component position on the irregularly shaped circuit board. Multiple circuit boards can be glued simultaneously, greatly improving the efficiency of the glue application process. Attached Figure Description

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0019] Example 1:

[0020] like Figures 1 to 2As shown, this embodiment discloses an electronic component dispensing device, including a table 1. Multiple feeding devices 2 are arranged on the table 1. Each feeding device 2 includes a feeding screw 3 and a feeding slide rod 5 arranged on the table 1. The feeding screw 3 is driven to rotate by a feeding motor 4. Each feeding screw 3 is provided with a slide table 6 threadedly connected to it. The feeding slide rod 5 passes through the slide table 6 and is slidably connected to it. Each slide table 6 has a vertical plate 7 fixed on it. A rotary motor 8 is fixed on the vertical plate 7. A support plate 9 is fixed to the output end of the rotary motor 8. Both sides of the support plate 9 are provided with fixed seats 10. The table 1 at the end of the feeding screw 3 is fixed with lamp covers 25. Ultraviolet lamps 26 are evenly fixed inside the lamp covers 25. The table 1 is also provided with a dispensing screw 15 and a dispensing slide bar 16. The dispensing screw 15 is driven to rotate by the dispensing motor 17. The dispensing screw 15 is provided with a slide plate 18 that is threadedly connected to the dispensing screw 15. The slide plate 18 is fixed with a lifting cylinder 19. The piston rod end of the lifting cylinder 19 is fixed with a mounting plate 20. The mounting plate 20 is fixed with a glue tube 21.The corresponding circuit board 12 is fixed above the support plate 9. Both ends of the circuit board 12 are engaged in the fixing grooves 11 of the corresponding fixing seats 10. After the circuit board 12 is fixed, the support plate 9 is rotated by the rotary motor 8, and the surface of the circuit board 12 at the position of the electronic component reaches a horizontal position. The feeding motor 4 drives the feeding screw 3 to rotate. When the feeding screw 3 rotates, the slide table 6 moves, and the circuit board 12 moves with the slide table 6. The circuit board 12 moves to below the slide plate 18. The dispensing motor 17 drives the dispensing screw 15 to rotate. When the dispensing screw 15 rotates, the slide plate 18 moves, and the dispensing needle 22 below the glue tube 21 reaches directly above the electronic component. The lifting cylinder 19 is activated, the glue tube 21 descends, and the dispensing needle... When the dispensing needle 22 reaches the position above the electronic component, since the tube 21 is filled with glue, there is a piston inside the tube 21 above the glue. The top of the tube 21 is connected to the air pump through an air pipe. During dispensing, the air pump fills the tube 21 above the piston with gas. The gas squeezes the piston, and the piston squeezes the glue, squeezing the glue out from the position of the dispensing needle 22. The glue is then applied to the electronic component on the circuit board 12 through the dispensing needle 22. After the electronic component is covered with UV glue, the air pump stops, the lifting cylinder 19 starts, the piston rod on the lifting cylinder 19 shortens, and the dispensing needle 22 rises. After the dispensing needle 22 reaches the designated position, the feeding motor 4 drives the feeding screw 3 to rotate, and the slide table 6 moves in the direction of the feeding screw 3. After the circuit board 12 moves into the lamp cover 25 along with the slide table 6, the power to the ultraviolet lamp 26 is turned on. The ultraviolet lamp 26 emits ultraviolet light, curing the UV adhesive. After the UV adhesive has initially cured after being exposed to ultraviolet light for a period of time, the slide table 6 is moved again under the slide plate 18, and the support plate 9 is rotated again by the rotary motor 8. The position of the electronic component to be glued on the next circuit board 12 reaches a horizontal position, and the glue application is repeated. This process is repeated until all the glued areas on the circuit board are fully glued and have initially cured. The circuit board is then removed and placed under the ultraviolet lamp to allow the adhesive to fully cure. When the glue on the circuit board 12 at one of the feeding devices 2 is cured, it can... This device can perform dispensing operations on electronic components in other feeding devices 2, greatly improving the dispensing efficiency of circuit boards 12. By fixing the irregularly shaped circuit board 12 on the support plate 9, the support plate 9 is rotated by the rotary motor 8, rotating the circuit board 12 at the electronic component mounting position to a horizontal state, and dispensing the electronic components, preventing the glue from slipping. After dispensing the electronic components at one position, the glue is cured by ultraviolet light. After the glue is cured, the glue is dispensed again at another electronic component position on the irregularly shaped circuit board 12, preventing the glue from flowing due to the circuit board flipping. Moreover, it can perform dispensing operations on multiple circuit boards 12 at the same time, greatly improving the dispensing efficiency.

[0021] Each mounting base 10 is fixed to a corresponding mounting plate 13, which is then fixed to a corresponding support plate 9 by bolts 14. Depending on the specifications of the circuit board 12, the corresponding mounting plate 13 is rotated, and both ends of the circuit board 12 are inserted into the mounting slots 11 on the mounting base 10 of the corresponding mounting plate 13.

[0022] A receiving cylinder 23 is fixed on the slide plate 18 below the glue tube 21, and a material tray 24 is fixed to the end of the piston rod of the receiving cylinder 23. When dispensing glue, the receiving cylinder 23 is activated, the piston rod on the receiving cylinder 23 is shortened, and the material tray 24 moves away from below the dispensing needle 22. After dispensing, the dispensing needle 22 rises, the dispensing cylinder is activated again, the piston rod on the dispensing cylinder is extended, and the material tray 24 reaches below the dispensing needle 22 to catch the glue dripping from the dispensing needle 22, preventing the glue from dripping onto the circuit board 12.

[0023] Example 2:

[0024] like Figure 3 As shown, this embodiment discloses an electronic component dispensing device. Based on the structure and principle of Embodiment 1, this embodiment has multiple sealing cylinders 27 fixed on the platform 1 on one side of the lampshade 25, and a baffle 28 is also provided on one side of the lampshade 25. The piston rod end of the sealing cylinder 27 is fixed to the corresponding baffle 28. When the UV adhesive cures, the sealing cylinder 27 is activated, the piston rod on the sealing cylinder 27 shortens, and the baffle 28 descends, blocking the ultraviolet lamp 26 through the baffle 28 to avoid light pollution.

[0025] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
