Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically, to a double-sided board drilling and pinning machine. Background Technology

[0002] In the electronics manufacturing industry, PCBs (printed circuit boards) are core components of electronic devices, and their manufacturing process is crucial. Pin encapsulation is a vital step in PCB manufacturing, designed to ensure the stability and reliability of the circuit board during subsequent processing or assembly through a series of precise operations.

[0003] The pin overlay process on a PCB generally includes the following steps:

[0004] Drilling and positioning: Pin holes are drilled in the copper plate. These pin holes not only serve as a reference for subsequent positioning and fixing, but also ensure precise alignment between the copper plate and other components.

[0005] Stacking the padding board with the copper plate: Using the pin holes as positioning points, the padding board (usually used to protect the bottom of the copper plate from damage) is stacked together with the copper plate.

[0006] Pin fixing: Insert pins through the pin holes to firmly fix the pad wood and copper plate together.

[0007] Aluminum foil stacking: A layer of aluminum foil is stacked on one side of the copper plate.

[0008] Tape wrapping: Finally, use tape to tightly wrap the wooden board, copper plates (multiple sheets), and aluminum foil together. This step forms a stable unit, providing a solid foundation for subsequent processing or assembly steps.

[0009] In existing PIN overmolding processes, drilling PIN holes and inserting pins typically require two separate steps, relying on a CCD vision positioning device and an automatic pin insertion device, respectively. However, these two production steps increase the production cycle and costs. Utility Model Content

[0030] It should be noted that in the existing PIN overmolding process, from drilling the PIN hole to inserting the pin, two separate steps are usually required, relying on a CCD vision positioning device and an automatic pin insertion device respectively. However, these two production steps increase the production cycle and production cost.

[0031] like Figures 1-3 As shown, this embodiment provides a double-sided panel drilling and pinning machine. The centering mechanism 20 and the automatic drilling and pinning mechanisms 30 on both sides work together to accurately position the double-sided panels, ensuring that the double-sided panels are in the correct position before drilling and pinning, thereby improving processing accuracy. It also integrates the drilling and pinning processes into one, which can significantly shorten the production cycle of double-sided panels and reduce production costs.

[0032] Specifically, a double-sided panel drilling and pinning machine includes a frame 10, on which a centering mechanism 20 and an automatic drilling and pinning mechanism 30 are provided. The centering mechanism 20 is located between two automatic drilling and pinning mechanisms 30, and the two automatic drilling and pinning mechanisms 30 are symmetrically arranged. The two automatic drilling and pinning mechanisms 30 are respectively located on both sides of the centering mechanism 20. This layout not only balances the workload, but also facilitates the simultaneous processing of both sides of the double-sided panel, thus improving work efficiency.

[0033] The lower part of the automatic drilling PIN mounting mechanism 30 is provided with an automatic drilling PIN moving drive module 40, which is used to adjust the distance between the two automatic drilling PIN mounting mechanisms 30. The automatic drilling PIN mounting mechanism 30 includes a drilling PIN mounting plate 31, an upper PIN module 32 and a drilling module 33. The upper PIN module 32 is located above the drilling PIN mounting plate 31, and the drilling module 33 is located below the drilling PIN mounting plate 31. The output end of the upper PIN module 32 and the output end of the drilling module 33 are in corresponding positions.

[0034] The output ends of the upper PIN module 32 and the drilling module 33 are positioned correspondingly to ensure that they can be accurately aligned to the same position during operation, thereby achieving a seamless connection between drilling and pin insertion.

[0035] In one embodiment, the centering mechanism 20 includes a centering lifting unit 21, a centering mounting plate 22, a centering main support plate 23, and a centering adjustment unit 24. The centering lifting unit 21 is connected to the centering mounting plate 22. The centering main support plate 23 and the centering adjustment unit 24 are both mounted on the centering mounting plate 22. There are two centering adjustment units 24, and the two centering adjustment units 24 are located on both sides of the centering mounting plate 22. The centering main support plate 23 and the two centering adjustment units 24 cooperate to support the double-panel panel, and the two centering adjustment units 24 cooperate to clamp the double-panel panel.

[0036] The centering main support plate 23 mainly supports the double panels, while the centering adjustment unit 24 assists in supporting the double panels and also clamps the double panels through fine adjustment to prevent the double panels from moving in the height direction.

[0037] In this embodiment, the centering lifting unit 21 is responsible for vertical movement to raise or lower the double-panel panel as needed. The centering lifting unit 21 includes a first lifting plate 211, a second lifting plate 212, a first lifting cylinder 213, and a second lifting cylinder 214. The output end of the first lifting cylinder 213 is connected to the first lifting plate 211, and the output end of the second lifting cylinder 214 is connected to the centering mounting plate 22. Both the first and second lifting cylinders 213 and 214 are mounted on the second lifting plate, with the output directions of the first and second lifting cylinders 213 and 214 being opposite. The first lifting cylinder 213 lifts the second lifting plate 212 and the centering mounting plate 22 in the reverse direction, while the second lifting cylinder 214 lifts the centering mounting plate 22 in the forward direction, adjusting the height of the centering mounting plate 22 from both the first and second lifting cylinders 213 and 214.

[0038] When centering the double-panel panels is required, the centering mounting plate 22, along with its main centering support plate 23 and centering adjustment unit 24, are first raised to an appropriate height through the coordinated operation of the first lifting cylinder 213 and the second lifting cylinder 214. Then, by adjusting the positions of the main centering support plate 23 and the two centering adjustment units 24, the double-panel panels are ensured to be stably and accurately supported and aligned.

[0039] In this embodiment, both centering adjustment units 24 are connected to the centering adjustment drive module 25. The centering adjustment drive module 25 is used to adjust the two centering adjustment units 24 to move away from or closer to each other. The centering adjustment units 24 are slidably mounted on the centering slide rails 222 arranged on the centering mounting plate 22. The centering adjustment unit 24 includes an auxiliary support frame 241, a centering side plate 242, a centering pressure plate 243, a centering offset cylinder 244, and a centering lifting cylinder 245. The auxiliary support frame 241 is slidably mounted on the centering adjustment drive module 25. The centering offset cylinder 244 is mounted on the auxiliary support frame 241. The output end of the centering offset cylinder 244 is connected to the centering side plate 242. The centering lifting cylinder 245 is mounted on the centering side plate 242, and the output end of the centering lifting cylinder 245 is connected to the centering pressure plate 243. The centering offset cylinder 244 offsets the centering side plate 242 and the centering pressure plate 243 mounted thereon in the horizontal direction, and the centering lifting cylinder 245 adjusts the height of the centering pressure plate 243 in the vertical direction to ensure that the double panels are stably clamped.

[0040] In this embodiment, the centering adjustment drive module 25 includes a centering adjustment motor 251, a centering adjustment drive wheel 252, a centering adjustment driven wheel 253, and a centering adjustment belt 254. The output end of the centering adjustment motor 251 is connected to the centering adjustment drive wheel 252, and the centering adjustment driven wheel 253 is connected to the centering adjustment drive wheel 252 through the centering adjustment belt 254.

[0041] When centering adjustment of the double-sided panel is required, the centering adjustment motor 251 starts, driving the centering adjustment drive wheel 252 to rotate. The centering adjustment belt 254 transmits the power of the centering adjustment drive wheel 252 to the centering adjustment driven wheel 253, thereby realizing the synchronous movement of the centering adjustment unit 24. By adjusting the rotation direction and speed of the centering adjustment motor 251, the centering adjustment unit 24 can be controlled to move away from or closer to the double-sided panel.

[0042] Meanwhile, the centering offset cylinder 244 and the centering lifting cylinder 245 can be finely adjusted in the horizontal and vertical directions respectively to ensure that the double panels are accurately clamped and centered.

[0043] In one embodiment, the upper PIN module 32 includes an upper PIN fixing frame 321, an upper PIN positioning drive module 322 and an upper PIN unit 323 mounted on the upper PIN fixing frame 321. An upper PIN slide rail 3211 is provided on the upper PIN fixing frame 321. The upper PIN unit 323 is slidably connected to the upper PIN slide rail 3211. The upper PIN unit 323 is also connected to the upper PIN positioning drive module 322 for driving the upper PIN unit 323 to slide along the upper PIN slide rail 3211 to achieve adjustment of the upper PIN unit 323 in the vertical direction.

[0044] In this embodiment, the upper PIN fixing bracket 321 is further provided with a pressing block 3212 and a pressure plate motor 3213. The output end of the pressure plate motor 3213 is connected to the pressing block 3212, which is used to press the double-sided panel. When the pressure plate motor 3213 is started, it drives the pressing block 3212 to move, thereby pressing the double-sided panel. The pressing block 3212 can apply pressure evenly and stably to the double-sided panel.

[0045] Before the process begins, the pressure plate motor 3213 starts, driving the holding block 3212 to move and hold the double-sided panel, ensuring that the double-sided panel remains stable during the process. The upper PIN positioning drive module 322 drives the upper PIN unit 323 to slide along the upper PIN slide rail 3211 to the PIN hole drilled on the double-sided panel and perform the PIN operation.

[0046] After the process is completed, the pressure plate motor 3213 drives the holding block 3212 to release the double panel, and the upper PIN positioning drive module 322 drives the upper PIN unit 323 to return to the initial position so as to perform the next process operation.

[0047] In one embodiment, the drilling module 33 includes a drilling bracket 331 and a pin hole positioning vision unit 332, a drilling positioning drive module, and a drilling unit 334 mounted on the drilling bracket 331. The pin hole positioning vision unit 332 is used to identify pre-positioned holes on the double-sided panel. A drilling slide rail 3311 is provided on the drilling bracket 331. The drilling unit 334 is slidably connected to the drilling slide rail 3311. The drilling unit 334 is also connected to the drilling positioning drive module for driving the drilling unit 334 to slide along the drilling slide rail 3311.

[0048] In this embodiment, the drilling unit 334 includes a telescopic drilling cylinder 3341 and a drilling spindle 3342. The drilling spindle 3342 is mounted on the cylinder rod of the telescopic drilling cylinder. A circular hole 311 is provided on the PIN mounting plate 31 of the drilling unit. The circular hole 311 on the PIN mounting plate 31 should be aligned with the predetermined drilling position on the double-sided panel to ensure drilling accuracy. The drill bit of the drilling spindle 3342 passes into the circular hole 311 on the PIN mounting plate 31 of the drilling unit to perform drilling operations on the double-sided panel. The telescopic drilling cylinder 3341 is mounted on the drilling fixture 331.

[0049] In one embodiment, a limiting unit is further provided on the PIN mounting plate 31 drilled through. The limiting unit includes a limiting cylinder 312 and a limiting block 313. The output end of the limiting cylinder 312 is connected to the limiting block 313. The limiting unit and the centering mechanism 20 cooperate to limit the double-sided panel. The limiting unit is responsible for limiting the double-sided panel during the drilling process to prevent it from moving.

[0050] Before drilling begins, the pin hole positioning vision unit 332 identifies the position of the pre-positioning hole on the double-sided panel and feeds the position information back to the limiting unit. The limiting unit makes a fine adjustment to the position of the double-sided panel to ensure that the pre-positioning hole is aligned with the round hole 311 on the PIN mounting plate 31 on the drilling.

[0051] The drilling positioning drive module drives the drilling unit 334 to move to the drilling position, the telescopic drilling cylinder 3341 is activated, and the drill bit of the drilling spindle 3342 is driven to pass into the round hole 311 on the PIN mounting plate 31 and perform drilling operation on the double-sided panel.

[0052] After drilling is completed, the telescopic drilling cylinder 3341 retracts the drill bit, the clamping unit releases the double-panel, and the drilling positioning drive module drives the drilling unit 334 back to the initial position for the next drilling operation.
