Abstract
Description
Technical Field
[0001] This utility model relates to a gantry electroplating line, and more particularly to an automatic lifting device for the anode baffle of a gantry line. Background Technology
[0002] In PCB gantry electroplating lines, the anode baffles are often manually adjusted during the electroplating process. This leads to several problems: First, manual adjustment of the anode baffle's position has significant accuracy errors, affecting the uniformity of PCB plating. Second, adjusting the anode baffle requires operators to climb above the plating tank, and the overhead crane must be moved to create space for adjustment. This method is not only inefficient but also unsafe. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an automatic lifting device for anode baffles of gantry lines that is convenient for adjusting the lifting position of the anode baffle, has high debugging efficiency, and is safe and reliable, in order to address the shortcomings of the existing technology.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.
[0005] An automatic lifting device for an anode baffle of a gantry mill includes a frame, an anode baffle, a lifting drive mechanism, and two traction cables. The frame is equipped with a lifting drive shaft, which is connected to the lifting drive mechanism. Traction discs are located at the left and right ends of the lifting drive shaft. The two traction cables are positioned near the left and right ends of the anode baffle, respectively. The first end of each traction cable is fixedly connected to the anode baffle, and the second end is fixedly connected to the outer circumference of the traction disc. Two pulley assemblies are provided on the frame corresponding to the two traction cables. The traction cables pass around the pulley assemblies. When the lifting drive mechanism drives the lifting drive shaft to rotate, the traction cables are wound around the outside of the traction discs, and the first ends of the two traction cables lift the anode baffle upwards.
[0006] Preferably, the pulley assembly includes a first fixed pulley, a second fixed pulley, and a third fixed pulley. The first fixed pulley is disposed adjacent to the traction disc, the second fixed pulley is disposed above the first fixed pulley, and the third fixed pulley is disposed adjacent to the second fixed pulley and is located above the anode baffle. The traction cable passes sequentially around the first fixed pulley, the second fixed pulley, and the third fixed pulley.
[0007] Preferably, the axle of the first fixed pulley extends in the left-right direction, and the axles of the second and third fixed pulleys extend in the front-back direction.
[0008] Preferably, the lifting drive mechanism is a motor drive mechanism.
[0009] Preferably, the anode baffle has two fixing holes near its upper edge for connecting the traction cable.
[0010] In the automatic lifting device for the anode baffle of the gantry electroplating line disclosed in this utility model, the frame serves as the main support structure of the gantry electroplating line, the anode baffle is located inside the frame, and the lifting drive mechanism is installed on the frame. Traction cables are respectively provided near the left and right ends of the anode baffle. The two ends of the traction cables are fixedly connected to the outer circumference of the anode baffle and the traction discs, respectively. When the lifting drive mechanism drives the lifting transmission shaft and the two traction discs, the two traction cables are simultaneously wound around the two traction discs, and the first ends of the two traction cables lift the anode baffle upwards, thereby realizing the upward movement of the anode baffle. When the anode baffle needs to be lowered, the lifting drive mechanism simply needs to reverse its rotation. Compared with the prior art, this utility model only requires electrical control to realize the lifting and lowering adjustment of the anode baffle, which not only facilitates the adjustment of the anode baffle's lifting position but also has higher debugging efficiency and is safer and more reliable in operation.

[0014] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.
[0015] This utility model discloses an automatic lifting device for the anode baffle of a gantry line, combined with Figures 1 to 3 As shown, it includes a frame 1, an anode baffle 2, a lifting drive mechanism 3, and two traction cables 6. The frame 1 is equipped with a lifting transmission shaft 4, and the lifting drive mechanism 3 is connected to the lifting transmission shaft 4. The left and right ends of the lifting transmission shaft 4 are respectively equipped with traction discs 5. The two traction cables 6 are respectively close to the left and right ends of the anode baffle 2. The first end of the traction cable 6 is fixedly connected to the anode baffle 2, and the second end of the traction cable 6 is fixedly connected to the outer circumference of the traction disc 5. The frame 1 is equipped with two pulley assemblies 7 corresponding to the two traction cables 6. The traction cables 6 pass around the pulley assemblies 7. When the lifting drive mechanism 3 drives the lifting transmission shaft 4 to rotate, the traction cables 6 are wrapped around the outside of the traction disc 5, and the first ends of the two traction cables 6 lift the anode baffle 2 upward.
[0016] In the above structure, the frame 1 serves as the main support structure of the gantry electroplating line. The anode baffle 2 is located inside the frame 1, and the lifting drive mechanism 3 is mounted on the frame 1. Traction cables 6 are respectively provided near the left and right ends of the anode baffle 2. The two ends of the traction cables 6 are fixedly connected to the outer circumference of the anode baffle 2 and the traction discs 5, respectively. When the lifting drive mechanism 3 drives the lifting transmission shaft 4 and the two traction discs 5, the two traction cables 6 are simultaneously wound around the two traction discs 5, and the first ends of the two traction cables 6 lift the anode baffle 2 upwards, thus realizing the upward movement of the anode baffle 2. When the anode baffle 2 needs to be lowered, the lifting drive mechanism 3 simply needs to reverse its rotation. Compared with the prior art, this utility model only requires electrical control to realize the lifting and lowering adjustment of the anode baffle, which not only facilitates the adjustment of the anode baffle's lifting position but also has higher debugging efficiency and is safer and more reliable in operation.
[0017] In a preferred embodiment, the pulley assembly 7 includes a first fixed pulley 70, a second fixed pulley 71, and a third fixed pulley 72. The first fixed pulley 70 is disposed adjacent to the traction disc 5, the second fixed pulley 71 is disposed above the first fixed pulley 70, and the third fixed pulley 72 is disposed adjacent to the second fixed pulley 71 and is located above the anode baffle 2. The traction cable 6 passes sequentially around the first fixed pulley 70, the second fixed pulley 71, and the third fixed pulley 72.
[0018] In the above structure, by setting the first fixed pulley 70, the second fixed pulley 71 and the third fixed pulley 72 at appropriate positions, the traction cable 6 can be extended and guided from the traction disc 5 to the anode baffle 2, thereby realizing lifting and lowering traction.
[0019] As a preferred method, combined Figure 1 and Figure 2 As shown, the axle of the first fixed pulley 70 extends in the left-right direction, and the axles of the second fixed pulley 71 and the third fixed pulley 72 extend in the front-back direction.
[0020] In this embodiment, the lifting drive mechanism 3 is a motor drive mechanism. The lifting drive mechanism 3 and the lifting transmission shaft 4 can be connected by a reduction gear assembly.
[0021] To facilitate the fixing of the traction cable 6, in this embodiment, the anode baffle 2 is provided with two fixing holes 20 for connecting the traction cable 6 near the upper edge.
[0022] Please see Figure 2In this embodiment, the frame 1 is provided with an upper position sensing switch 8 and a lower position sensing switch 9 arranged adjacent to the traction cable 6, and the traction cable 6 is provided with a position trigger 10. When the upper position sensing switch 8 and the lower position sensing switch 9 sense the position trigger 10, they respectively emit electrical signals.
[0023] In the above structure, the distance between the upper position sensing switch 8 and the lower position sensing switch 9 is the same as the lifting and lowering stroke of the anode baffle 2. When the upper position sensing switch 8 senses the position trigger 10, it indicates that the anode baffle 2 has risen to the specified height position. When the lower position sensing switch 9 senses the position trigger 10, it indicates that the anode baffle 2 has fallen to the specified height position.
[0024] In practical applications, the upper position sensing switch 8 and the lower position sensing switch 9 can be proximity switches, and the position trigger 10 can be a metal baffle.
[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
