Description

TECHNICAL FIELD

[0001] The utility model relates to PCB circuit board processing technical field, concretely relates to a kind of multi-station punching device for PCB circuit board processing. BACKGROUND

[0002] In the field of PCB circuit board processing, drilling process is a crucial link, which is directly related to the electrical connection of the circuit board, component installation and overall performance. With the rapid development of electronic technology, the application of PCB circuit board is increasingly widespread, and the requirements for processing efficiency and precision are also increasingly high. However, in the existing PCB circuit board processing process, especially for multi-station punching operation, there are some problems to be solved.

[0003] Currently, the existing PCB circuit board punching device on the market often has the problem of inconvenient drilling clamping processing when processing multiple circuit boards. Specifically, the traditional punching device mostly adopts single-station or fixed clamping mode. This mode may still meet the demand when processing a single circuit board, but once it involves batch processing of multiple circuit boards, it is not up to the task. On the one hand, single-station processing efficiency is low and cannot meet the demand of large-scale production; on the other hand, the fixed clamping mode is difficult to adapt to circuit boards of different sizes and shapes, and loose clamping can cause drilling position deviation, affecting processing precision.

[0004] In addition, the existing punching device often lacks effective positioning and adjustment mechanism when clamping multiple circuit boards, making the circuit boards prone to displacement or deformation during processing, further exacerbating drilling errors. This not only increases the difficulty of subsequent electroplating, welding and other processes, but also may cause the entire circuit board to be scrapped, causing huge economic losses to enterprises.

A kind of punching device for PCB circuit board processing is made by using the above technical scheme, waste chips generated during PCB circuit board punching process can be collected by suction fan, placing plate, air outlet and scrap collecting box, and the suction force generated by suction fan can adsorb PCB circuit board, saving the use cost of traditional fixed clamping device.

[0006] However, in practical use, the above structure is not convenient for clamping and drilling multiple circuit boards at the same time, which indirectly reduces the drilling efficiency of circuit boards. Utility Model Content

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figures 1-2 As shown, a multi-station drilling device for PCB circuit board processing includes a housing 1 and multiple limiting parts 2 disposed on the top of the housing 1. The multi-station drilling device also includes an adjusting clamping mechanism 3 and a drilling collection mechanism 4. The adjusting clamping mechanism 3 is disposed on the top of the housing 1 and includes an abutment part 31, a connecting part 32, a mounting frame 33, and a sliding part 34. Multiple abutment parts 31 are slidably disposed on the top of the housing 1, and all abutment parts 31 are located beside the limiting parts 2. The connecting part 32 is disposed on top of the multiple abutment parts 31. The mounting frame 33 is disposed on the top of the housing 1 and is located beside the abutment parts 31. The sliding part 34 is slidably disposed on top of the mounting frame 33 and is connected to the connecting part 32. The drilling collection mechanism 4 is disposed on the top of the housing 1.

[0029] When drilling is required on a circuit board to be drilled, the circuit board is first placed beside multiple limiting parts 2 using a robotic arm. Then, multiple sliding parts 34 drive the connecting parts 32 and multiple abutting parts 31 to slide along the mounting frame 33 until the abutting parts 31 abut against the side of the limiting parts 2. This allows for simultaneous clamping and drilling of multiple circuit boards, and also enables the clamping of circuit boards of different diameters.

[0030] See Figures 2-4 As shown, the adjusting clamping mechanism 3 also includes a setting plate 35 and a first telescopic cylinder 36; the setting plate 35 is installed on the top of the mounting bracket 33 and is located above the housing 1; the first telescopic cylinder 36 is installed on the side of the setting plate 35 and the output end of the first telescopic cylinder 36 is connected to the sliding part 34.

[0031] When multiple abutment parts 31 need to be moved to clamp the circuit board to be processed, the first telescopic cylinder 36 is activated first. When the first telescopic cylinder 36 is activated, it can drive the sliding part 34 and the connecting part 32 to move along the mounting bracket 33. When the connecting part 32 moves, it can drive multiple abutment parts 31 to move simultaneously.

[0032] See Figures 2-4 As shown, the adjusting clamping mechanism 3 also includes a rotating rod 37 and a swinging abutment arm 38; the rotating rod 37 is rotatably disposed on the top of the housing 1 and is located below the mounting bracket 33; there are multiple swinging abutment arms 38 which are respectively disposed outside the rotating rod 37, and the multiple swinging abutment arms 38 are all located on the side of the limiting part 2.

[0033] When the abutment part 31 moves, the circuit board to be processed can be abutted between the limiting part 2 and the abutment part 31. At this time, the circuit board to be processed is clamped on both sides. Then the rotating rod 37 rotates, which drives the multiple swinging abutment parts 31 to flip over. Until the multiple swinging abutment arms 38 are located beside the limiting part 2.

[0034] See Figure 3 and Figure 4 As shown, the adjusting clamping mechanism 3 also includes a first rotary driver 39, a second telescopic cylinder 391, and a pushing part 392; the first rotary driver 39 is disposed on the top of the housing 1, and the output end of the first rotary driver 39 is connected to the rotating rod 37; the second telescopic cylinder 391 has multiple cylinders and is disposed on the side of the swing abutment arm 38; the pushing part 392 is disposed on the output end of the second telescopic cylinder 391.

[0035] When the first rotary driver 39 is activated, it drives the rotating rod 37 and multiple swinging abutment arms 38 to rotate synchronously. When the swinging abutment arms 38 are located beside the limiting part 2, the second telescopic cylinder 391 is activated and drives the pushing part 392 to move until the pushing part 392 contacts the circuit board to be processed. At this time, the circuit board to be processed can be clamped and limited by the limiting part 2, the abutment part 31, and the pushing part 392. This ensures the stability of the circuit board to be processed during the subsequent drilling process.

[0036] See Figure 5 and Figure 6 As shown, the drilling collection mechanism 4 includes a fixed plate 41, a limiting frame 42, and a displacement block 43; there are multiple fixed plates 41, which are respectively disposed on the top of the housing 1, and the multiple fixed plates 41 are all located on the side of the limiting part 2; there are multiple limiting frames 42, which are respectively disposed on the top of the fixed plates 41; there are multiple displacement blocks 43, which are respectively slidably disposed on the top of the limiting frame 42.

[0037] The top of the displacement block 43 is provided with a displacement groove. A pair of support frames are provided on the side of the limiting frame 42. Both support frames are connected to the fixing plate 41 and form a triangular support structure.

[0038] See Figure 5 and Figure 6 As shown, the drilling and collecting mechanism 4 also includes a first linear actuator 44, a third telescopic cylinder 45, and a drilling device 46; the first linear actuator 44 has multiple units and is respectively disposed on the side of the limiting frame 42, and the output end of the first linear actuator 44 is connected to the displacement block 43; the third telescopic cylinder 45 has multiple units and is respectively disposed at the bottom of the displacement block 43; the drilling device 46 has multiple units and is respectively disposed at the output end of the third telescopic cylinder 45.

[0039] When drilling is required on the clamped circuit board to be processed, the first linear actuator 44 is activated and drives the displacement block 43 to move along the limiting frame 42. As the displacement block 43 moves, it drives the third telescopic cylinder 45 and the drilling device 46 to move synchronously. Then, the third telescopic cylinder 45 is activated and drives the drilling device 46 to descend, after which the drilling device 46 can drill holes in the clamped circuit board to be processed.

[0040] See Figure 5 and Figure 6 As shown, the drilling collection mechanism 4 also includes a movable frame 47 and a dust collection device 48; the movable frame 47 has multiple units and is slidably disposed on the side of the abutment portion 31; the dust collection device 48 has multiple units and is disposed on the top of the movable frame 47, and the multiple dust collection devices 48 are all located on the side of the limiting portion 2.

[0041] When it is necessary to collect the waste debris generated during the drilling process, the dust collection device 48 is activated, which can effectively collect the waste debris generated during the drilling process.

[0042] See Figure 5 and Figure 6 As shown, the borehole collection mechanism 4 also includes a second rotary driver 49 and a rotary wheel 491; the second rotary driver 49 has multiple components and is respectively disposed on the top of the movable frame 47; the rotary wheel 491 is disposed at the output end of the second rotary driver 49.

[0043] When it is necessary to adjust the position of the movable frame 47 and the dust collection device 48, the second rotary drive 49 is activated and drives the rotating wheel 491 to rotate. When the rotating wheel 491 rotates, it can drive the movable frame 47 to move along the top of the abutment part 31. This allows for adjustment of the position of the dust collection device 48, facilitating better collection of waste.

[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
