Description

Technical Field

[0001] This utility model relates to the field of electrostatic spraying technology, specifically to an electrostatic spraying device for insulating varnish on electronic components. Background Technology

[0002] Electronic components are the basic building blocks of electronic devices. After production, they usually need to be coated with insulating varnish using electrostatic spraying equipment. Electrostatic attraction is used to make the charged varnish mist adhere evenly, forming a protective layer and improving the insulation performance and service life of the components.

[0003] In most existing spraying devices, the clamping of electronic components makes it difficult to spray them from multiple angles, resulting in uneven coating of certain areas and obvious dead zones and missed areas. To spray these areas, manual contact with the electronic components and readjustment of their clamping position may be required. However, this manual contact and adjustment may damage the electronic components due to electrostatic discharge or damage the coating film in already coated areas. Therefore, this invention aims to provide an electrostatic spraying device for insulating varnish on electronic components that can uniformly spray coating from multiple angles.

[0030] 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.

[0031] Example: Please refer to Figures 1 to 7 According to an embodiment of the present invention, a technical solution is provided: an electrostatic spraying device for insulating varnish of electronic components, including a workbench 1 having a working space 2; a spray gun 3 electrically connected to an electrostatic generator on the workbench 1, and the spray gun 3 connected to an external varnish supply device; a conductive part 4 disposed at the top of the working space 2 and electrically connected to a ground wire; a conductive clamping part for clamping electronic components; and a locking part for fixing the conductive clamping part and the conductive part 4 relative to each other to restrict or allow the conductive clamping part to rotate along the axial direction of the conductive part 4.

[0032] The electrostatic spraying device for insulating varnish of electronic components with the above structure allows users to perform electrostatic spraying on electronic components. First, the conductive clamping part is used to clamp and fix the electronic components. Since the conductive clamping part is connected to the conductive part 4, and the conductive part 4 is electrically connected to the ground wire, the electronic components are grounded and form a positive electrode. When the user operates the spray gun 3, the high voltage generated by the electrostatic generator causes the sprayed insulating varnish particles to carry a negative charge. These charged particles are attracted by the grounded electronic components and are evenly attached to the surface of the components. By adjusting the locking part 1, the user can rotate the conductive clamping part along the axis of the conductive part 4, thereby achieving the operation of adjusting the orientation of the electronic components without touching them, so that the user can spray the electronic components from multiple directions.

[0033] Specifically, the electrostatic generator can be a high-voltage electrostatic generator capable of generating 60-100kV negative high voltage electricity; the paint supply equipment can be a pressure tank type paint supply system equipped with a constant pressure pump and a filter device to ensure a stable and impurity-free supply of insulating paint.

[0034] In this embodiment, a movable part 5 is installed on the top of the workspace 2, and a movable groove 6 with an inverted T-shaped structure is opened at the bottom of the movable part 5. The conductive part 4 is slidably disposed in the movable groove 6, and the conductive part 4 has an inverted T-shaped structure. This arrangement allows the conductive part 4 to slide freely in the movable groove 6 along the horizontal direction of the workspace 2, thereby expanding the operating range of the spraying operation and making it easier for users to adjust the optimal spraying position according to electronic components of different sizes and shapes.

[0035] In this embodiment, the conductive clamping part includes a conductive plate 7, a conductive clamping member 1 8, a conductive clamping member 2 9, a driving part, and a locking part 2; both the conductive clamping member 1 8 and the conductive clamping member 2 9 are elastic; both the conductive clamping member 1 8 and the conductive clamping member 2 9 have an arc-shaped structure; the conductive plate 7 is provided with the conductive clamping member 1 8 and the conductive clamping member 2 9 at relatively intervals; the driving part is used to drive the bottom ends of the conductive clamping member 1 8 and the conductive clamping member 2 9 to move closer or further apart; the locking part 2 is used to lock the conductive clamping member 1 8 and the conductive clamping member 2 9 together. When the bottom ends of conductive clamp 8 and conductive clamp 29 are close to each other, the movement of conductive clamp 8 relative to conductive clamp 29 is restricted or allowed. This configuration enables the clamping and adjustment of electronic components of different sizes. The distance between the bottom ends of conductive clamp 8 and conductive clamp 29 can be controlled by the drive unit to accommodate electronic components of different sizes. The locking part 2 can selectively restrict the relative movement between conductive clamp 8 and conductive clamp 29 to ensure that the electronic components are stably clamped and fixed.

[0036] In this embodiment, the driving unit includes a first driving block 10, a second driving block 11, and a third driving block 12. A slot 13 is formed along the height direction of the conductive plate 7, and the first driving block 10 is slidably disposed in the slot 13. Slots 2 14 and 3 15 are respectively formed opposite to each other on the sidewall of the conductive plate 7, and the second driving block 11 and the third driving block 12 are slidably disposed within slots 2 14 and 3 15, respectively. The top ends of the first conductive clamping member 8 and the second conductive clamping member 9 are rotatably disposed on opposite sides of the sidewall of the first driving block 10. The middle ends of the first conductive clamping member 8 and the second conductive clamping member 9 are rotatably disposed on the sidewall of the second driving block 11 and the third driving block 12, respectively. With this configuration, when the user pulls down on the first driving block 10, the bottom ends of the two clamping members move away from each other, facilitating the rapid release of electronic components. Conversely, when the user pushes the first driving block 10 upwards, the bottom ends of the two clamping members move closer together, thereby clamping the electronic components.

[0037] Specifically, during the process of the user pulling down the drive block 10, the tops of the conductive clamping member 18 and the conductive clamping member 29 will move down accordingly, while simultaneously driving the drive block 21 and the drive block 32 to slide outwards within the slots 24 and 35. At this time, as the distance between the middle ends of the conductive clamping member 18 and the conductive clamping member 29 increases, the distance between the bottom ends of the conductive clamping member 18 and the conductive clamping member 29 also increases accordingly. More specifically, when the driving block 10 moves downward from the top, it generates a downward pulling force, causing the top ends of the conductive clamping parts 1 and 2 to move downward synchronously. Simultaneously, since the middle ends of the conductive clamping parts 1 and 2 form fixed rotational fulcrums with the driving blocks 2 and 3, 12, the conductive clamping parts 1 and 2 rotate around their respective middle ends. This rotational motion causes the bottom ends of the conductive clamping parts 1 and 2 to move in opposite directions, thereby releasing the clamped electronic components. Conversely, when the user pushes the drive block 10 upward, the drive block 10 moves upward, causing the tops of the conductive clamping member 1 8 and the conductive clamping member 2 9 to move upward synchronously. At the same time, the drive block 2 11 and the drive block 3 12 slide inward within the slots 2 14 and 3 15, causing the middle ends of the two clamping members to move inward. During this process, as the distance between the middle ends of the conductive clamping member 1 8 and the conductive clamping member 2 9 decreases, the distance between the bottom ends of the conductive clamping member 1 8 and the conductive clamping member 2 9 also decreases accordingly, so as to achieve the clamping and fixing of electronic components.

[0038] In this embodiment, the bottom walls of slot 2 14 and slot 3 15 are recessed downwards to form limiting slot 1 16 and limiting slot 2 17, and the bottoms of driving block 2 11 and driving block 3 12 protrude downwards to form limiting block 1 33 and limiting block 2 34. Limiting block 1 33 and limiting block 2 34 are slidably disposed in limiting slot 1 16 and limiting slot 2 17, respectively. This arrangement ensures the stability of the movement of driving block 2 11 and driving block 3 12 within slot 2 14 and slot 3 15, and prevents driving block 2 11 and driving block 3 12 from tilting or detaching during movement.

[0039] In this embodiment, the locking part 2 includes a locking post 18, a locking block 19, an abutment block 22, and a spring 23. The locking post 18 is fixed to the top of the drive block 10. The top wall of the slot 13 is recessed upward to form a locking groove 21. A locking cavity 20 is defined in the conductive plate 7. The locking cavity 20 communicates with the locking groove 21. The locking block 19 is slidably disposed in the locking cavity 20. The first end of the locking block 19 extends movably into the locking groove 21. The abutment block 22 is fixed to the second end of the locking block 19 and is slidably disposed in the locking cavity 20. The spring 23 elastically abuts against the abutment block 22. The first end of the locking block 19 has a downward inclined surface. The locking post 18 has a locking opening 25 suitable for the first end of the locking block 19 to be movably inserted. With this configuration, the automatic locking and rapid release of the drive block 10 position are achieved.

[0040] Specifically, when the drive block 10 moves upward to the predetermined position, the top of the locking post 18 contacts the inclined surface of the locking block 19. During this movement, the top of the locking post 19 will push against and retract towards the locking cavity 20. Subsequently, under the elastic force of the spring 23, the first end of the locking block 19 will automatically insert into the locking port 25, thereby locking the drive block 10 in this position. At this time, the electronic components are clamped and fixed by the bottom ends of the conductive clamping member 8 and the conductive clamping member 9, maintaining a stable state for the spraying operation. When the user needs to release the electronic components, he only needs to pull the abutment block 22 in the opposite direction. The abutment block 22 drives the locking block 19 to move, overcoming the elastic force of the spring 23, so that the first end of the locking block 19 exits from the locking port 25. At this time, the drive block 10 can move downward freely.

[0041] In this embodiment, a second spring 24 is sleeved on the locking post 18, and the second spring 24 elastically abuts against the first driving block 10; this arrangement allows the first driving block 10 to quickly reset after being unlocked, so as to pre-clamp the next electronic component.

[0042] In this embodiment, the conductive plate 7 is provided with an unlocking groove 26, which is connected to the locking cavity 20. An unlocking post 28 is fixed on the free end face of the abutment block 22, and an unlocking rod 27 is fixed on the unlocking post 28. The unlocking rod 27 is slidably disposed in the unlocking groove 26. With this configuration, when the user needs to release the electronic components, he / she only needs to hold the unlocking rod 27 made of insulating material and pull it along the direction of the unlocking groove 26. The unlocking rod 27 drives the unlocking post 28 and the abutment block 22 to move, thereby causing the locking block 19 to disengage from the locking port 25 and realizing the unlocking of the drive block 10.

[0043] In this embodiment, the unlocking lever 27 is configured with an insulating material; this is to prevent static electricity from being transmitted to the user's body through the unlocking lever 27, thus ensuring the user's personal safety during operation.

[0044] In this embodiment, the locking part includes a conductive screw 29, a flange 30, and a nut 31; the flange 30 is fixed to the bottom of the conductive part 4, the conductive screw 29 is fixed to the top of the conductive plate 7, and the nut 31 is threadedly connected to the conductive screw 29; a rod 32 is installed on the conductive part 4; this arrangement realizes a detachable fixing method between the conductive part 4 and the conductive plate 7.

[0045] Specifically, after the conductive screw 29 passes through the flange 30, the conductive part 4 and the conductive plate 7 can be firmly connected together by tightening the nut 31. At the same time, since all components are made of conductive materials, a complete conductive path from the ground wire to the electronic components is ensured, so that the electronic components can be effectively grounded to form a positive electrode. In addition, when the user needs to rotate the conductive part 4 to adjust the spraying angle of the electronic components, the conductive plate 7 and the conductive screw 29 can be disassembled and reassembled by loosening the nut 31, the optimal spraying position can be found, and then the nut 31 can be tightened to fix it, so that the user can easily control the rotation angle of the conductive plate 7.

[0046] 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.
