Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment technology, specifically to an automatic copper plating equipment for circuit boards. Background Technology

[0002] To enable some circuit boards to achieve better functionality, a layer of rubber is often glued onto these circuit boards through a vulcanization process. To improve the adhesion, the surface of the circuit board needs to be impregnated with rubber before vulcanization.

[0003] In existing technologies, after the circuit board is impregnated with adhesive, it needs to be lifted and left to stand, allowing the residual adhesive to drip off. At this time, the circuit board clamping structure of traditional copper wire bonding equipment is relatively complex, which makes it inconvenient to load and unload the circuit board. Moreover, the loading and unloading of the circuit board is always above the impregnation area, which poses a risk that the circuit board may fall off during the loading and unloading stages and be difficult to pick up. In addition, the dripping adhesive can easily contaminate the adhesive below, thereby affecting the subsequent impregnation effect and reducing the overall use effect. Utility Model Content

Two vertical plates are welded to the top surface of the workbench, and a horizontal bar is fixed between the two vertical plates. Guide rails are welded to both the upper and lower surfaces of the horizontal bar, and a walking device is arranged below the horizontal bar. A support plate is welded to the top surface of the walking device, and an upper guide wheel is installed on the upper surface of the support plate. A drive shaft is installed on the lower surface of the support plate via a bearing seat. A lower guide wheel is fixed to the surface of the drive shaft, and the lower guide wheel... The guide rails on the bottom surface of the crossbar are rolled together, and the upper guide wheel is rolled together with the guide rails on the top surface of the crossbar. Two auxiliary wheels are symmetrically arranged on the top surface of the walking device. An electric cylinder is fixedly installed on the right side wall of the walking device, and a bearing plate is fixed to the bottom of the electric cylinder by bolts. Several clamps are hung on the bottom surface of the bearing plate. A servo motor is fixed inside the walking device, and a transmission belt connected to the transmission shaft is provided at the output end of the servo motor. A glue-impregnation tank and a recycling tank are arranged on the top surface of the workbench from left to right, and the top surfaces of the glue-impregnation tank and the recycling tank are both open.

[0008] Furthermore, a steel mesh is welded and installed on the inner side of the recycling bin, and an outlet with a manual valve is provided at the bottom of the recycling bin, with a tapered part on the lower surface of the recycling bin corresponding to the outlet.

[0009] Furthermore, the open end of the impregnation tank is welded with a frame, and two sloping surfaces are symmetrically arranged on the inner side of the frame. The surface of the workbench is provided with a mounting opening corresponding to the impregnation tank.

[0010] Furthermore, the top surface of the bearing plate is provided with a guide rod that is interlocked with the walking device, and a limit block is provided at one end of the guide rod that extends into the walking device.

[0011] Furthermore, both auxiliary wheels are rolledly connected to the guide rail on the bottom surface of the crossbar, and the two auxiliary wheels are on the same horizontal line as the lower guide wheel.

[0012] Furthermore, the upper guide wheel, lower guide wheel, and auxiliary wheel are all provided with circular grooves in the middle, and the cross-section of the guide rail is an isosceles trapezoidal structure.

[0013] Furthermore, the clamp consists of two clamps, and one of the clamps has a hook at its tail end. The bottom surface of the support plate has a semi-circular hanging lug corresponding to the hook of the clamp.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an automatic copper plating equipment for circuit boards, which has the following advantages:

[0016] (1) In this utility model, by starting the servo motor in the walking device, the transmission belt wound around the output end of the servo motor drives the transmission shaft to rotate. Since the upper guide wheel of the support plate is connected to the guide rail on the top surface of the crossbar, and the lower guide wheel of the support plate is connected to the guide rail on the bottom surface of the crossbar, and two auxiliary wheels are symmetrically set on the top surface of the walking device, as the transmission shaft drives the lower guide wheel to rotate, the walking device moves smoothly along the length of the crossbar. When the bearing plate is below the impregnation tank, the electric cylinder is started to extend, so that several circuit boards held by the clamps on the bearing plate can be immersed in the glue in the impregnation tank, realizing the impregnation treatment of the circuit boards before vulcanization. Compared with the prior art, it has the advantages of walking automatic impregnation and convenient circuit board loading and unloading.

[0017] (2) In this utility model, an impregnation box and a recycling box are arranged sequentially from left to right on the workbench. When the walking device moves from above the impregnation box to above the recycling box, the circuit boards held by the clamps on the support plate will drip excess glue during the lateral movement. At this time, the opening on the top of the recycling box can collect the dripping glue. The steel mesh set in the recycling box serves as a support structure to facilitate the passage of glue, so that the circuit boards that accidentally fall off the clamps can fall into the surface of the steel mesh instead of falling directly into the glue in the recycling box. Compared with the prior art, this is not only beneficial for the recycling of glue after the circuit boards are impregnated, but also convenient for picking up the fallen circuit boards.

[0026] According to an embodiment of the present invention, an automatic copper plating equipment for circuit boards is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, an automatic copper plating equipment for circuit boards according to an embodiment of the present invention includes a workbench 1. Two vertical plates 4 are welded to the top surface of the workbench 1, and a crossbar 5 is fixed between the two vertical plates 4. Guide rails 8 are welded to both the upper and lower surfaces of the crossbar 5. A traveling device 6 is arranged below the crossbar 5. A support plate 7 is welded to the top surface of the traveling device 6, and an upper guide wheel 18 is mounted on the upper surface of the support plate 7. A transmission shaft 16 is mounted on the lower surface of the support plate 7 via a bearing seat. A lower guide wheel 17 is fixed to the surface of the transmission shaft 16 and is tactilely connected to the guide rail 8 on the bottom surface of the crossbar 5. The upper guide wheel 18 is tactilely connected to the guide rail 8 on the top surface of the crossbar 5. Two auxiliary wheels 20 are symmetrically arranged on the top surface of the traveling device 6. An electric... The electric cylinder 13 is bolted to a support plate 11 at its bottom. Several clips 12 are mounted on the bottom surface of the support plate 11. A servo motor 15 is fixed inside the walking device 6. A transmission belt 19, which is wound around the transmission shaft 16, is provided at the output end of the servo motor 15. A glue-impregnating tank 2 and a recycling tank 3 are provided on the top surface of the workbench 1 from left to right. Both the top surfaces of the glue-impregnating tank 2 and the recycling tank 3 are open. The servo motor 15 and the electric cylinder 13 are controlled by manually starting and stopping the switch. The wiring diagram of the power components and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0028] In one embodiment, a steel mesh 10 is welded and installed on the inner side of the recycling bin 3, and an outlet nozzle 9 with a manual valve is provided at the bottom of the recycling bin 3. A tapered part is provided on the lower surface of the recycling bin 3 corresponding to the outlet nozzle 9. With this structure, the circuit board that is accidentally detached from the clip 12 can fall into the surface of the steel mesh 10 instead of falling directly into the adhesive in the recycling bin 3. This is beneficial for the recycling of the adhesive after the circuit board is impregnated with adhesive, and also facilitates the picking up of the detached circuit board.

[0029] In one embodiment, the open end of the impregnation tank 2 is welded with a frame 21, and two sloping surfaces 22 are symmetrically arranged on the inner side of the frame 21. The surface of the workbench 1 is provided with a mounting opening corresponding to the impregnation tank 2. With this structure, it is easy to support and load / unload the impregnation tank 2. The function of the two sloping surfaces 22 is to reduce splashing and loss during the glue injection stage.

[0030] In one embodiment, the top surface of the support plate 11 is provided with a guide rod 14 that is inserted and connected to the walking device 6, and a limit block is provided at one end of the guide rod 14 that extends into the interior of the walking device 6. This structure increases the stability of the lifting and lowering of the support plate 11.

[0031] In one embodiment, both auxiliary wheels 20 are rolledly connected to the guide rail 8 on the bottom surface of the crossbar 5, and the two auxiliary wheels 20 and the lower guide wheel 17 are on the same horizontal line. This structure increases the stability of the lateral movement of the walking device 6.

[0032] In one embodiment, the upper guide wheel 18, the lower guide wheel 17, and the auxiliary wheel 20 are all provided with circular grooves in the middle, and the cross section of the guide rail 8 is an isosceles trapezoidal structure. This structure increases the reliability of the connection between the upper guide wheel 18, the lower guide wheel 17, and the auxiliary wheel 20 and the guide rail 8.

[0033] In one embodiment, the clamp 12 consists of two clamps, and one of the clamps of the clamp 12 is provided with a hook at its tail end. The bottom surface of the support plate 11 is provided with a semi-circular hanging lug corresponding to the hook of the clamp 12. With this structure, it is easy to load, unload and replace the clamp 12.

[0034] Working principle: First, the circuit board to be impregnated is clamped on the clamp 12 of the support plate 11. The servo motor 15 in the walking device 6 is started, causing the transmission belt 19 wound on the output end of the servo motor 15 to drive the transmission shaft 16 to rotate. Since the upper guide wheel 18 of the support plate 7 is connected to the guide rail 8 on the top surface of the crossbar 5, and the lower guide wheel 17 of the support plate 7 is connected to the guide rail 8 on the bottom surface of the crossbar, and two auxiliary wheels 20 are symmetrically arranged on the top surface of the walking device 6, as the transmission shaft 16 drives the lower guide wheel 17 to rotate, the walking device 6 moves smoothly laterally along the length of the crossbar 5. When the support plate 11 is below the impregnation tank 2, the electric cylinder 13 is activated to extend, causing several circuit boards clamped by the clamp 12 on the support plate 11 to be immersed in the impregnation tank 2. The circuit board is impregnated in the adhesive solution before vulcanization. After impregnation, the electric cylinder 13 is activated to retract and reset, causing the circuit board on the support plate 11 to detach from the impregnation tank 2. At the same time, when the walking device 6 moves from above the impregnation tank 2 to above the recycling tank 3, the circuit boards held by the clamps 12 on the support plate 11 drip excess adhesive during the lateral movement. At this time, the opening on the top surface of the recycling tank 3 can collect the dripping adhesive. The steel mesh 10 set inside the recycling tank 3 serves as a support structure to facilitate the passage of adhesive, so that circuit boards that accidentally fall off the clamps 12 can fall onto the surface of the steel mesh 10 instead of falling directly into the adhesive solution in the recycling tank 3. This is beneficial for the recovery of adhesive solution after the circuit board is impregnated and also facilitates the picking up of the detached circuit boards.
