Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading platforms, in particular to an anti-collision mechanism for a copper deposition line loading and unloading platform. Background Technique

[0002] The gantry chemical copper deposition line loading and unloading platform is used for loading and unloading printed circuit boards that need to undergo chemical copper deposition. In order to increase the copper deposition output, the chemical copper deposition basket is usually designed with multiple layers, generally a 25-layer design. In this way, when loading and unloading 25 layers of printed circuit boards in one operation, the required loading and unloading time is relatively long.

[0003] After retrieval, in the prior art, the publication number is: CN210030936U, which discloses a gantry electroplating line composite push-pull type loading and unloading platform, including an electroplating tank. A pair of guide rail brackets are symmetrically arranged on the left and right sides of the electroplating tank. A pair of guide rails are arranged on the pair of guide rail brackets. The left and right sides of the traveling crane are mounted on the pair of guide rails at the bottom. An elevating mechanism and a front and rear driving mechanism are arranged on the traveling crane. A pair of loading and unloading plate platforms are symmetrically arranged on the front left and right sides of the electroplating tank. The front and rear ends of the pair of loading and unloading plate platforms sequentially form a loading plate platform position and an unloading plate platform position. V-shaped seats for fixing the flying bar are respectively arranged on the pair of loading and unloading plate platforms corresponding to the loading plate platform position and the unloading plate platform position; a push-pull type water collecting tray is arranged between the bottoms of the pair of loading and unloading plate platforms; limit switches are arranged at the innermost sides of the inner side surfaces of the pair of loading and unloading plate platforms, and an infrared safety switch is arranged on the demarcation line between the loading plate platform position and the unloading plate platform position. This utility model can reduce the electroplating cycle time, improve the production capacity of the electroplating line, exert the maximum potential of the electroplating line, and improve economic benefits.

[0004] However, in some special cases, such as when the product supply is insufficient, the operator is not skilled, etc., the time for loading and unloading products exceeds the cycle time set by the traveling crane operation program. When the cycle time arrives, the traveling crane will automatically travel to the loading and unloading platform to lift the flying bar and take away the loaded and unloaded printed circuit boards for copper deposition production. At this time, if the operator is still working on the loading and unloading platform, the traveling crane will hit the operator, thus causing a safety accident. Therefore, an anti-collision mechanism for a copper deposition line loading and unloading platform is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-collision mechanism for a copper deposition line loading and unloading platform, which blocks the traveling crane by setting an anti-collision mechanism to prevent the traveling crane from causing harm to workers when they have not completed the assembly, so as to solve the problems raised in the above background technique.

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , the present utility model provides an anti-collision mechanism for the loading and unloading platform of the electroless copper plating line, including a support 1, and further including an electroless copper plating tank 2, a traveling crane 5 and an anti-collision mechanism. Guide rails are respectively opened on both side surfaces of the support 1, and the traveling crane 5 is slidably arranged inside the guide rails;

[0027] The anti-collision mechanism includes a double-headed motor 16, which is fixedly installed on the side wall of the chemical copper plating tank 2 inside the bracket 1. The output shafts at both ends of the double-headed motor 16 are respectively fixedly installed with rotating rods and gears 17. The gears 17 are meshed and connected to the side wall of the toothed plate 18. Through grooves 15 are respectively opened inside the guide rails opened on the surface of the bracket 1, and the toothed plate 18 is slidably connected to the inner wall of the through groove 15.

[0028] By respectively arranging liftable toothed plates 18 below the guide rails opened on the surface of the bracket 1, and the toothed plate 18 is slidably connected to the inner wall of the through groove 15 opened inside the guide rail, so as to drive the gear 17 to rotate by starting the double-headed motor 16, and then make the toothed plate 18 rise to physically block the traveling crane 5, avoiding the traveling crane 5 from starting when the workers have not completed the assembly and causing personal injury to the workers.

[0029] In this embodiment, as Figure 4 shown, vertical plates 19 are respectively installed on both sides of the bottom surface of the guide rail where the chemical copper plating tank 2 is located. Limiting grooves 20 are respectively opened on the side walls of the vertical plates 19 facing the toothed plate 18. Limiting blocks 21 are arranged on the side walls of the toothed plate 18, and the limiting blocks 21 are slidably connected to the inner walls of the limiting grooves 20.

[0030] At the same time, limiting grooves 20 are respectively opened on the side walls of the vertical plates 19 facing the toothed plate 18, and limiting blocks 21 are arranged on the side walls of the toothed plate 18. The limiting blocks 21 slide inside the limiting grooves 20. When the toothed plate 18 is driven to rise and fall, the limiting blocks 21 slide inside the limiting grooves 20 to ensure the direction of the toothed plate 18 during lifting and lowering, and increase the stability of the toothed plate 18 during lifting and lowering.

[0031] In a further preferred embodiment, as Figure 2 shown, a baffle 14 for protecting the double-headed motor 16 is further arranged above the double-headed motor 16 on the side wall of the chemical copper plating tank 2. By arranging a baffle 14 for protecting the double-headed motor 16 above the double-headed motor 16 on the side wall of the chemical copper plating tank 2, it is possible to prevent the chemical agent inside the chemical copper plating basket 8 from dripping into the double-headed motor 16 when the chemical copper plating basket 8 is taken out of the chemical copper plating tank 2, corroding the components inside the double-headed motor 16 and affecting the service life of the double-headed motor 16.

[0032] Furthermore, as Figure 4 shown, the limiting block 21 is located in the middle of the side wall of the toothed plate 18 and a limiting plate is arranged at the bottom end of the toothed plate 18. By arranging the limiting block 21 in the middle of the side wall of the toothed plate 18, the rising distance of the toothed plate 18 is also determined by the limiting block 21, avoiding the toothed plate 18 from disengaging from the gear 17.

[0033] Furthermore, as Figure 2As shown, the anti-collision mechanism further includes an infrared safety switch 9. The infrared safety switch 9 is arranged on the inner wall of one end of the bracket 1 away from the chemical copper plating tank 2. A receiver is arranged on the inner wall of the bracket 1 opposite to the infrared safety switch 9.

[0034] Also, by arranging the infrared safety switch 9 on the inner wall of one end of the bracket 1 away from the chemical copper plating tank 2, and a receiver is arranged on the inner wall of the bracket 1 opposite to the infrared safety switch 9. When personnel are working, the human body blocks the infrared rays, indicating that there is someone above the pedal 13. The signal is transmitted to the traveling crane 5, so that the traveling crane 5 cannot move over to hoist the chemical copper plating basket 8 above the support plate 10.

[0035] Furthermore, as Figure 2 shown, the anti-collision mechanism still includes a fixing plate 12 and a pedal 13. The fixing plate 12 is fixedly installed on the side wall of the bottom plate at one end of the bracket 1 away from the chemical copper plating tank 2. The pedal 13 is arranged on the surface of the fixing plate 12. A pressure sensor is arranged between the fixing plate 12 and the pedal 13.

[0036] By arranging the fixing plate 12 and the pedal 13, the pedal 13 is arranged above the fixing plate 12 and a pressure sensor is arranged between the fixing plate 12 and the pedal 13. Due to the weight of the operator (generally greater than 40 kg), the pressure sensing switch on the pedal is actuated, and the pressure signal controls the traveling crane not to move over, essentially eliminating the possibility of the traveling crane hitting people.

[0037] Preferably, as Figure 1 shown, a traveling crane button 3 is further arranged on the side wall of the traveling crane 5. The traveling crane button 3 is linearly connected to the infrared safety switch 9, the pressure sensor and the double-headed motor 16 through a controller. By arranging the traveling crane button 3 to be linearly connected to the infrared safety switch 9, the pressure sensor and the double-headed motor 16 through the controller, so that after the infrared safety switch 9 and the pressure sensor transmit the signals to the traveling crane button 3, the traveling crane button 3 then sends a signal to the double-headed motor 16 to control the double-headed motor 16 to start.

[0038] In addition, as Figure 1 shown, lifting belts 4 are symmetrically arranged on the bottom surface of the traveling crane 5. Hooks 6 are arranged below the lifting belts 4. The hooks 6 are hung with the upper ends of the flying bars 7. The side walls below the flying bars 7 are installed with the hanging walls on both sides of the chemical copper plating basket 8 through bolts.

[0039] It should be noted that, as Figure 1 shown, support plates 10 are symmetrically arranged on the surface of the bottom plate between the brackets 1. V-shaped seats 11 for placing the chemical copper plating basket 8 are arranged on the top surfaces of the support plates 10. The inner walls of the V-shaped seats 11 are respectively in contact with the side walls at the bottom ends of the flying bars 7.

[0040] Among them, asFigure 2 As shown, multiple groups of partitions for placing circuit boards are provided inside the chemical copper plating basket 8.

[0041] When in use by workers, a pressure sensor is provided between the pedal 13 and the fixed plate 12. When an operator is working on the surface of the pedal 13, since the weight of the operator (generally greater than 40 kg) causes the pressure sensor on the pedal not to send a signal, the pressure signal controls that the traveling crane cannot move over. When the worker leaves the pedal 13, the pressure sensor and the infrared safety switch 9 simultaneously transmit signals to the traveling crane button 3 through the controller, and the traveling crane button 3 then transmits a signal to the double-headed motor 16, causing the double-headed motor 16 to rotate in the reverse direction, which will drive the toothed plate 18 to descend, and the traveling crane 5 can then travel above the chemical copper plating basket 8 to hoist the chemical copper plating basket 8.

[0042] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations on the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
