Description

Technical Field

[0001] This invention relates to the field of coating technology, specifically to a double-sided, high-efficiency workpiece coating fixture. Background Technology

[0002] In the production process of circuit boards, in order to protect the circuit boards, a coating process is required. Coating involves applying a layer of material to the surface of the circuit board to enhance its resistance to corrosion, scratches, and the adhesion of ink printing. In fact, the surface of the circuit board is very smooth, and electroplating and printing are generally quite difficult, so some surface treatment is required.

[0003] However, existing double-sided workpiece coating fixtures require rotating the workpiece during use, which can cause the workpiece to collide with the coating nozzle, resulting in damage to the workpiece and failing to meet user needs. Therefore, a more efficient double-sided workpiece coating fixture is needed. Summary of the Invention

[0004] The purpose of this invention is to address the problem in existing technologies where rotating the workpiece during double-sided coating can lead to collisions with the coating nozzle. This invention aims to overcome the shortcomings of existing technologies and design a high-efficiency double-sided workpiece coating fixture.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A double-sided high-efficiency workpiece coating fixture includes a coating frame and a flipping mechanism disposed on the coating frame. The flipping mechanism includes a working component, a flipping component, and a lifting component.

[0007] The working components include a pneumatic push rod, a sliding toothed plate, and a connecting gear. The pneumatic push rod is fixedly connected to the outer wall of the coating frame. The output end of the pneumatic push rod is equipped with a sliding toothed plate that is slidably connected to the outer wall of the coating frame. The meshing surface of the sliding toothed plate is engaged with the connecting gear.

[0008] The flipping assembly includes a rotating shaft and a rotating frame. The outer wall of the connecting gear is fixedly connected to the rotating shaft, which is spun onto the outer wall of the coating frame. One end of the rotating shaft is fixedly connected to the rotating frame.

[0009] The lifting assembly includes a connecting rod, a lifting bracket, a limiting groove, and a coating nozzle. The connecting rod is screwed onto the outer wall of the rotating frame, and the lifting bracket is screwed onto the top of the connecting rod. A limiting groove is provided at the connection between the lifting bracket and the coating frame, and the coating nozzle is fixedly connected to the outer wall of the lifting bracket.

[0010] Preferably, a clamping push rod is fixedly connected to the end of the rotating frame away from the connecting rod. The output end of the clamping push rod is equipped with a sliding perforated plate that is slidably connected to the outer wall of the rotating frame. A positioning guide groove is provided on the outer wall of the sliding perforated plate. A connecting column is movably connected to the inner wall of the positioning guide groove. A limit guide groove is provided at the connection between the connecting column and the rotating frame. A positioning clamping plate is fixedly connected to one end of the connecting column. The workpiece is attached to the outer wall of the positioning clamping plate. A feeding conveyor belt is provided on the side of the outer wall of the coating frame located on the pneumatic push rod. A discharging conveyor belt is provided on the outer wall of the coating frame away from the feeding conveyor belt.

[0011] Preferably, the rotating shaft forms a rotating structure with the coating frame via a sliding toothed plate and a connecting gear.

[0012] Preferably, the rotation angle of the rotating shaft is 180°, and the central axis of the rotating shaft coincides with the center of the rotating frame.

[0013] Preferably, the lifting bracket forms a lifting structure with the limiting slide groove through the rotating frame and connecting rod.

[0014] Preferably, two sets of positioning guide grooves are provided, and the positioning guide grooves are inclined in shape.

[0015] Preferably, the connecting column forms a sliding structure between the positioning guide groove and the limiting guide groove.

[0016] The present invention has the following beneficial effects:

[0017] 1. By setting up a rotating frame, the sliding toothed plate slides and meshes with the connecting gear to drive the rotating shaft to rotate 180°. The rotation of the rotating shaft drives the workpiece on the outer wall of the rotating frame to rotate synchronously. At the same time, the rotation of the rotating frame drives the coating nozzle on the outer wall of the lifting bracket to slide vertically along the outer wall of the limiting slide groove through the connecting rod, thereby avoiding collision between the rotating frame and the coating nozzle while rotating.

[0018] 2. By setting a positioning clamp, the sliding plate slides and drives the two sets of positioning guide grooves to slide synchronously. This causes the positioning guide grooves to slide along the outer wall of the limiting guide groove. The sliding of the connecting column causes the positioning clamp to fit against the outer edge of the workpiece, thus achieving the positioning operation of the workpiece and preventing the position of the workpiece from changing relative to the coating nozzle after the workpiece is flipped.

[0024] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 1-3 As shown, the present invention proposes a double-sided high-efficiency workpiece coating fixture, which includes a coating frame 1 and a flipping mechanism disposed on the coating frame 1. The flipping mechanism includes a working component, a flipping component and a lifting component.

[0027] The working components include a pneumatic push rod 2, a sliding toothed plate 3, and a connecting gear 4. The pneumatic push rod 2 is fixedly connected to the outer wall of the coating frame 1. The output end of the pneumatic push rod 2 is equipped with a sliding toothed plate 3 that is slidably connected to the outer wall of the coating frame 1. The meshing surface of the sliding toothed plate 3 is engaged with the connecting gear 4.

[0028] The flipping assembly includes a rotating shaft 5 and a rotating frame 6. The outer wall of the connecting gear 4 is fixedly connected to the rotating shaft 5, which is spun onto the outer wall of the coating frame 1. One end of the rotating shaft 5 is fixedly connected to the rotating frame 6.

[0029] The lifting assembly includes a connecting rod 7, a lifting bracket 8, a limiting groove 9, and a coating nozzle 10. The connecting rod 7 is screwed onto the outer wall of the rotating frame 6, and the lifting bracket 8 is screwed onto the top of the connecting rod 7. A limiting groove 9 is provided at the connection between the lifting bracket 8 and the coating frame 1, and the coating nozzle 10 is fixedly connected to the outer wall of the lifting bracket 8.

[0030] In this embodiment, the rotating shaft 5 forms a rotating structure with the coating frame 1 through the sliding toothed plate 3 and the connecting gear 4. During operation, it is beneficial for the pneumatic push rod 2 to work and drive the sliding toothed plate 3 to slide along the outer wall of the coating frame 1. The sliding toothed plate 3 drives the rotating shaft 5 to rotate 180° by meshing with the connecting gear 4, thereby realizing the control operation of rotating shaft 5 rotating 180°.

[0031] In this embodiment, the rotation angle of the rotating shaft 5 is 180°, and the central axis of the rotating shaft 5 coincides with the center of the rotating frame 6. During operation, it is beneficial for the rotating shaft 5 to rotate and drive the workpiece 17 on the outer wall of the rotating frame 6 to rotate synchronously, so that after the rotating frame 6 rotates 180°, it is not necessary to position the other coating surface of the workpiece 17.

[0032] In this embodiment, the lifting bracket 8 forms a lifting structure with the rotating frame 6 and the connecting rod 7 and the limiting slide groove 9. During operation, the rotating frame 6 rotates and drives the coating nozzle 10 on the outer wall of the lifting bracket 8 to slide vertically along the outer wall of the limiting slide groove 9 through the connecting rod 7, thereby avoiding the collision between the rotating frame 6 and the coating nozzle 10 while the rotating frame 6 is rotating.

[0033] Example 2

[0034] like Figure 3 and 4 As shown, the present invention proposes a double-sided high-efficiency workpiece coating fixture. Compared with Embodiment 1, as another embodiment of the present invention, a clamping push rod 11 is fixedly connected to the end of the rotating frame 6 away from the connecting rod 7. A sliding perforated plate 12 that is slidably connected to the outer wall of the rotating frame 6 is installed at the output end of the clamping push rod 11. A positioning guide groove 13 is opened on the outer wall of the sliding perforated plate 12. A connecting column 14 is movably connected to the inner wall of the positioning guide groove 13. A limit guide groove 15 is opened at the connection part between the connecting column 14 and the rotating frame 6. A positioning clamping plate 16 is fixedly connected to one end of the connecting column 14. The outer wall of the positioning clamping plate 16 is in contact with the rotating frame 6. There is a workpiece 17 to be processed. The outer wall of the coating frame 1 is provided with a feeding conveyor belt 18 on one side of the pneumatic push rod 2. The outer wall of the coating frame 1 away from the feeding conveyor belt 18 is provided with a discharging conveyor belt 19. During operation, it is beneficial for the clamping push rod 11 to work and drive the sliding hole plate 12 to slide along the outer wall of the rotating frame 6. The sliding hole plate 12 drives the two sets of positioning guide grooves 13 to slide synchronously. In turn, the positioning guide grooves 13 slide and drive the connecting column 14 to slide along the outer wall of the limiting guide groove 15. The sliding of the connecting column 14 drives the positioning clamping plate 16 to fit against the outer edge of the workpiece 17 to achieve the positioning operation of the workpiece 17.

[0035] In this embodiment, two sets of positioning guide grooves 13 are provided. The positioning guide grooves 13 are inclined in shape. During operation, by providing positioning guide grooves 13, it is beneficial for the sliding plate 12 to slide and drive the two sets of positioning guide grooves 13 to slide synchronously, so as to avoid the position of the workpiece 17 relative to the coating nozzle 10 changing after the workpiece 17 is flipped.

[0036] In this embodiment, the connecting column 14 forms a sliding structure between the positioning guide groove 13 and the limiting guide groove 15. During operation, the positioning guide groove 13 slides to drive the connecting column 14 to slide along the outer wall of the limiting guide groove 15. The sliding of the connecting column 14 drives the positioning clamp 16 to fit against the outer edge of the workpiece 17, thereby realizing the positioning operation of the workpiece 17.

[0037] Working principle: First, the operator places the workpiece 17 on the feeding conveyor belt 18. The feeding conveyor belt 18 pushes the workpiece 17 into the rotating frame 6 inside the coating frame 1. Then, the workpiece 17 is positioned. The clamping push rod 11 drives the sliding plate 12 to slide along the outer wall of the rotating frame 6. The sliding plate 12 drives the two sets of positioning guide grooves 13 to slide synchronously. In turn, the positioning guide grooves 13 slide and drive the connecting column 14 to slide along the outer wall of the limiting guide groove 15. The connecting column 14 slides and drives the positioning clamping plate 16 to fit against the outer edge of the workpiece 17, thus realizing the positioning operation of the workpiece 17.

[0038] Next, the coating nozzle 10 works to evenly coat the coating liquid onto the outer wall of the workpiece 17. Then, the other side of the workpiece 17 is coated. The pneumatic push rod 2 works to drive the sliding toothed plate 3 to slide along the outer wall of the coating frame 1. The sliding toothed plate 3 slides and meshes with the connecting gear 4 to drive the rotating shaft 5 to rotate 180°. The rotation of the rotating shaft 5 drives the workpiece 17 on the outer wall of the rotating frame 6 to rotate synchronously. At the same time, the rotation of the rotating frame 6 drives the coating nozzle 10 on the outer wall of the lifting bracket 8 to slide vertically along the outer wall of the limiting slide groove 9 through the connecting rod 7, thereby avoiding the collision between the rotating frame 6 and the coating nozzle 10 while rotating.

[0039] Finally, the coating nozzle 10 applies the coating liquid evenly to the other side of the workpiece 17. Then, the positioning clamp 16 moves away from the outer edge of the workpiece 17, and the coated workpiece 17 is unloaded by the unloading conveyor belt 19.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
