Description

Technical Field

[0001] This invention relates to the field of PCBA board processing technology for blood glucose meters, specifically a pre-forming processing component for processing PCBA boards for blood glucose meters. Background Technology

[0002] As a commonly used medical testing device in home and clinical settings, the core function of a blood glucose meter relies on the high-precision signal processing capabilities of its built-in PCBA board. The blood glucose meter PCBA board integrates weak signal acquisition, amplification, conversion, and main control modules, carrying out core functions such as test strip electrode signal recognition, micro-current signal amplification, and data conversion and display. It is characterized by dense components, fine wiring, high precision requirements, and stringent anti-interference requirements, and must comply with the IEC 60601 medical electrical safety standard. Its processing precision, board surface cleanliness, and structural flatness are far superior to those of ordinary civilian electronic circuit boards.

[0003] Currently, the manufacturing process of PCBA boards for blood glucose meters commonly employs traditional whole-board stamping and cutting techniques, which have several drawbacks in actual production. Firstly, traditional processing methods lack targeted pre-positioning and pre-leveling structures, making the PCBA board substrate prone to micro-warping and surface deformation. This leads to defects such as component misalignment, cold solder joints, and detachment in subsequent SMT (Surface Mount Technology) and precision chip soldering processes, directly affecting the accuracy of acquiring weak sensor signals from the blood glucose meter and causing data deviation. Secondly, existing processing equipment lacks dedicated dust removal and anti-static pre-processing structures. The delicate wiring areas of the PCBA board easily attract dust and static electricity residue, causing micro-short circuits and signal interference, failing to meet the production standards for medical-grade circuit boards. Summary of the Invention

[0011] Preferably, a plurality of inner sleeves are fixedly installed at the bottom of the ventilation duct, and an outer sleeve is slidably installed on the outer side of the plurality of inner sleeves away from the end of the ventilation duct. A pressing block is fixedly installed at the bottom of the outer sleeve, and a rubber pressure pad is fixedly installed at the bottom of each pressing block. An outer sleeve is fixedly installed at the top of each pressing block, and an inner sleeve rod is slidably installed inside the top of the outer sleeve, and the top of the inner sleeve rod is fixedly connected to the bottom of the ventilation duct.

[0012] Preferably, a spring is fixedly installed on the top of the pressing block, and the spring is sleeved on the outside of the outer sleeve and the inner sleeve rod, and the top of the outer sleeve is fixedly connected to the bottom of the ventilation pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: through the meshing transmission of servo motor, gear and external gear ring, the rotation of the placement turntable is driven to realize multi-station automatic feeding, which can continuously complete the pre-forming processing of multiple blood glucose meter PCBA boards, eliminating the need for frequent manual loading and unloading, greatly improving the mass production processing efficiency. At the same time, with the linkage structure of lifting bending rod and ejection component, the processed workpiece can be automatically ejected, making material picking convenient and labor-saving.

In addition, a composite angle slotted exhaust structure is adopted. The exhaust slot is set with a dual-dimensional air duct with a vertical downward angle of 30° and a horizontal tangential tilt. Relying on the reaction force of the ion air jet, the pressing structure rotates at a low speed, forming a spiral airflow field. This completely eliminates the cleaning blind spots of traditional fixed blowers. Ion airflow is output synchronously throughout the stamping process. It can accurately blow away the fine debris and copper slag generated by cutting, avoid the squeezing and scratching of the PCB precision circuit and solder mask layer by hard particles, eliminate the risk of micro short circuits, and neutralize the static electricity generated by stamping friction in real time. It can prevent static electricity from adsorbing dust and interfering with components. It is fully compatible with the anti-static and high-cleanliness processing standards of medical-grade blood glucose meter PCBA boards, significantly reducing the defect rate and improving product processing quality and testing accuracy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-7This invention provides a technical solution: a pre-formed processing assembly for processing a blood glucose meter PCBA board, including a bottom support platform 1, a support column 3 fixedly installed on the top of the bottom support platform 1, a limiting seat 21 fixedly installed on the outer side of the support column 3, a placement assembly installed on the outer side of the limiting seat 21, a top frame plate 7 fixedly installed on the top of the support column 3, an electric cylinder fixing seat 6 fixedly installed on the top of the top frame plate 7, a stamping electric cylinder 5 fixedly installed inside the electric cylinder fixing seat 6, an assembly assembly fixedly installed at the output end of the stamping electric cylinder 5, and a stamping and cutting assembly installed at the bottom of the assembly assembly; a shield 10 fixedly installed on the top of the bottom support platform 1, and a [missing information - likely a component or component] fixedly installed on the outer side of the shield 10. The control box 15 includes a placement assembly comprising a placement turntable 2, which is rotatably mounted on the outside of a limiting seat 21. The placement turntable 2 has multiple placement slots 13 inside, each containing a fixed bottom placement plate 12. An external gear ring 20 is fixedly mounted on the bottom of the placement turntable 2. A servo motor 16 is fixedly mounted on the top of the bottom support platform 1. A drive gear 17 is fixedly mounted on the output end of the servo motor 16, and the outer side of the drive gear 17 meshes with the outer side of the external gear ring 20. The assembly assembly includes a mounting base 8, with an assembly slot 23 at the bottom. Two assembly slots 22 are symmetrically arranged on the top of the inner cavity of the assembly slot 23. A stamping and cutting assembly is also included. The component includes a ventilation duct 41, with a stamping and cutting blade 9 fixedly installed at the bottom of the ventilation duct 41 and an assembly plate 38 fixedly installed at the top of the ventilation duct 41. Two assembly clips 36 are symmetrically fixedly installed on the top of the assembly plate 38. The outer dimensions of the assembly plate 38 match the inner dimensions of the assembly slot 23, and the outer dimensions of the two assembly clips 36 match the inner dimensions of the two assembly slots 22. The positions of the two assembly clips 36 and the two assembly slots 22 are respectively aligned. Both the assembly clips 36 and the mounting base 8 have locking holes 37 inside, and locking rods 24 are inserted into the locking holes 37. Multiple inner sleeves 29 are fixedly installed at the bottom of the ventilation duct 41. An outer sleeve 28 is slidably installed on the outer side of the inner sleeve 29 away from the end of the ventilation duct 41. A pressing block 31 is fixedly installed at the bottom of the outer sleeve 28. A rubber pressure pad 30 is fixedly installed at the bottom of each pressing block 31. An outer sleeve 32 is fixedly installed at the top of each pressing block 31. An inner sleeve rod 34 is slidably installed inside the top of the outer sleeve 32. The top of the inner sleeve rod 34 is fixedly connected to the bottom of the ventilation duct 41. A spring 33 is fixedly installed at the top of the pressing block 31. The spring 33 is sleeved on the outside of the outer sleeve 32 and the inner sleeve rod 34. The top of the outer sleeve 32 is fixedly connected to the bottom of the ventilation duct 41.

[0026] The working principle of the above technical solution: The equipment as a whole uses the bottom support platform 1 as a bearing base, and together with multiple sets of support columns 3 at the top, it forms a stable vertical support frame, which ensures the structural rigidity and smooth operation of the whole machine stamping operation, effectively avoiding processing deviations caused by high-speed stamping vibration. After the equipment is turned on, the parameters are initialized through the control box 15 and it enters the standby state. The staff places the blood glucose meter PCBA boards to be pre-formed into the placement slots 13 that are evenly distributed around the circumference of the placement turntable 2. Each PCBA board is flattened and supported by the bottom placement plate 12. The slot body of the placement slot 13 is used to limit the initial positioning of the workpiece, prevent the board from shifting, and complete the workpiece loading and placement operation in batches, preparing for subsequent automated continuous stamping processing. After the formal start of processing, the control box 15 sends a command to drive the servo motor 16 on the top of the bottom support platform 1 to rotate at a constant speed. The output end of the servo motor 16 drives the drive gear 17 to rotate synchronously. Through the precise meshing transmission between the drive gear 17 and the outer gear ring 20 at the bottom of the placement turntable 2, the placement turntable 2 is driven to rotate smoothly around the inner axis of the limit seat 21. The limit seat 21 plays a role in radial limit and rotational support for the placement turntable 2, ensuring that there is no eccentricity or shaking during the rotation of the turntable. Through precise gear ratio transmission, the placement slot 13 loaded with PCBA boards to be processed can be precisely indexed and transferred to the top stamping and cutting component directly below, realizing the automated and precise workpiece repositioning and fixed-point feeding. No manual alignment is required, the positioning accuracy is high, and it can meet the needs of multi-station continuous cycle processing. After the workpiece is precisely positioned, the stamping cylinder 5, which is fixed to the top of the top plate 7 by the electric cylinder fixing seat 6, is started. The electric cylinder fixing seat 6 locks and fixes the stamping cylinder 5 to offset the stamping impact force and ensure stable power output. The output end of the stamping cylinder 5 extends vertically downward, driving the mounting seat 8 at the bottom and the entire stamping and cutting assembly to descend at a uniform speed. Before the cutter contacts the workpiece, the rubber pressure pads 30 at the bottom of the multiple sets of pressing blocks 31 first contact the surface of the blood glucose meter PCBA board. The rubber material achieves flexible contact, avoiding rigid extrusion that could scratch the precision circuitry and resistors. The solder layer, together with the sliding guide of the inner sleeve rod 34 and the outer sleeve 32, and the elastic buffering effect of the spring 33, uniformly and flexibly presses the board material at multiple points. It can adaptively fit the surface of the thin PCBA board and effectively offset the board material vibration, slight warping and slippage problems during the stamping process. It provides a stable processing benchmark for subsequent high-precision cutting. After the single-station PCBA board pre-forming cutting and slag removal process is completed, the stamping electric cylinder 5 retracts and resets, driving the entire stamping and cutting assembly to move vertically upward, completely separating from the workpiece processing area, and completing the stamping reset action. The equipment can quickly complete the disassembly and replacement of stamping and cutting components according to the processing requirements of blood glucose meter PCBA boards of different specifications and sizes. During disassembly, manually pull out the locking rod 24 that is inserted into the mounting base 8 and the assembly clip 36 to release the locking limit. Then the assembly clip 36 and assembly plate 38 can be slid out from the assembly slot 1 22 and assembly slot 2 23 respectively, realizing the overall quick disassembly of the stamping and cutting components. When installing new components, align the assembly plate 38 and assembly clip 36 with the corresponding slots for precise engagement and docking to ensure assembly accuracy and coaxiality. Finally, insert the locking rod 24 to lock and fix. This clamping and locking structure has a small assembly gap, high positioning accuracy, and is convenient and efficient to disassemble and assemble without professional tools. It can be quickly adapted to the pre-forming stamping processing of multiple PCBA boards, greatly improving the equipment's versatility and changeover processing efficiency.

[0027] In another implementation scheme, such as Figures 1-7 As shown, an ejector rod 40 is slidably installed inside the turntable 2. An ejector block 11 is fixedly installed on the top of the ejector rod 40, and an abutting protrusion 18 is fixedly installed on the bottom of the ejector rod 40. The bottom of the abutting protrusion 18 is higher than the top of the drive gear 17. The ejector block 11 is slidably installed on the inner side of the bottom placement plate 12. A lifting bending rod 19 is fixedly installed on the top of the bottom support platform 1, and the position of the lifting bending rod 19 corresponds to the position of the abutting protrusion 18.

[0028] Servo motor 16 restarts, driving the placement turntable 2 to continue indexing and rotating. The processed workpiece rotates synchronously with the turntable, causing the bottom contact protrusion 18 to gradually approach and contact the lifting bending rod 19 fixed to the top of the bottom support platform 1. Relying on the fixed pushing and limiting effect of the lifting bending rod 19, the contact protrusion 18 is subjected to an upward force, which drives the ejector rod 40 and ejector block 11 to slide vertically upward smoothly along the inner side of the bottom placement plate 12, smoothly ejecting the processed PCBA board from the groove structure. This facilitates quick material removal by workers or robotic arms, eliminating the need for manual removal of workpieces throughout the process, avoiding the risk of bending and scratching of the board, and completing a single automated processing cycle.

[0029] In another implementation scheme, such as Figures 1-7 As shown, the bottom of the ventilation pipe 41 is provided with an air guide groove 35, which is connected to the top of the inner sleeve 29. The top of the pressing block 31 is provided with an air guide groove 25. An exhaust sleeve 27 is movably installed on the outside of the pressing block 31. An exhaust groove 26 is provided on the outside of the exhaust sleeve 27. The bottom of the air guide groove 25 is connected to the inside of the exhaust sleeve 27. One side of the ventilation pipe 41 is connected to a ventilation tube 39. A ventilation box 4 is fixedly installed on the top of the top frame plate 7. The bottom of the ventilation box 4 is connected to a flexible air guide tube 14. The outer contour of the flexible air guide tube 14 away from the ventilation box 4 is matched with the inner contour of the ventilation tube 39.

[0030] While the stamping assembly presses the workpiece downwards, the vent box 4 at the top of the top frame plate 7 starts supplying air, continuously delivering dry and clean ionized airflow into the ventilation pipe 41 through the flexible and bendable air guide pipe 14 and ventilation pipe 39. The airflow is split along the internal cavity of the ventilation pipe 41, and is guided into the inner sleeves 29 through the evenly distributed air guide grooves 35 at the bottom, and then guided into the outer movable exhaust sleeve 27 through the air guide groove 25 inside the pressing block 31. The exhaust grooves 26 on the side wall of the exhaust sleeve 27 adopt a dual-dimensional composite inclined slotting structure: vertically, they are uniformly inclined downwards at 30° towards the cutting gap of the stamping cutting blade 9, ensuring that the airflow is accurately aligned with the stamping operation area; horizontally, along the... The exhaust sleeve 27 is arranged at an angle along its circumferential tangential direction. When the high-speed ion airflow is ejected, the downward-sloping airflow component continuously sweeps away PCB substrate debris, copper foil slag, and dust generated during cutting. Combined with the bottom negative pressure collection structure, the slag is quickly discharged. The tangential airflow component generates a reverse torque, driving the exhaust sleeve 27 and the pressing structure to rotate at a low speed and in a stable manner, forming a 360° blind-spot-free spiral airflow field. The stamping and cutting blade 9 continues to descend with the component to complete the pre-forming cutting of the PCBA board outline, slots, and positioning holes. The ion airflow can simultaneously neutralize the static electricity generated by stamping friction, eliminating the problems of static electricity adsorbing dust, damaging precision components, and causing signal interference, thus greatly improving the cleanliness of the board surface and the safety of processing.

[0031] Working principle: The equipment is supported by a bottom support platform 1 as a base, which, together with multiple sets of top support columns 3, forms a stable vertical support frame. This ensures the structural rigidity and smooth operation of the stamping process and effectively avoids processing deviations caused by high-speed stamping vibration. After the equipment is turned on, the parameters are initialized through the control box 15 and the equipment enters the standby state. The operator places the blood glucose meter PCBA boards to be pre-formed into the placement slots 13 that are evenly distributed around the circumference of the placement turntable 2. Each PCBA board is supported by the bottom placement plate 12. The placement slot 13 is used to limit the workpiece and achieve the initial positioning of the workpiece, preventing the board from shifting. The batch workpiece loading and placement operation is completed, preparing for the subsequent automated continuous stamping process. After the formal start of processing, the control box 15 sends a command to drive the servo motor 16 on the top of the bottom support platform 1 to rotate at a constant speed. The output end of the servo motor 16 drives the drive gear 17 to rotate synchronously. Through the precise meshing transmission between the drive gear 17 and the outer gear ring 20 at the bottom of the placement turntable 2, the placement turntable 2 is driven to rotate smoothly around the inner axis of the limit seat 21.

After the workpiece is precisely positioned, the stamping cylinder 5, which is fixed to the top of the top frame plate 7 by the electric cylinder fixing seat 6, is started. The electric cylinder fixing seat 6 locks and fixes the stamping cylinder 5 to offset the stamping impact force and ensure stable power output. The output end of the stamping cylinder 5 extends vertically downward, driving the mounting seat 8 at the bottom and the entire stamping and cutting assembly to descend at a uniform speed. Before the cutter contacts the workpiece, the rubber pressure pads 30 at the bottom of the multiple sets of pressing blocks 31 first contact the surface of the blood glucose meter PCBA board. The rubber material achieves flexible contact, avoiding rigid extrusion that scratches the precision circuit and solder mask layer. At the same time, with the sliding guide of the inner sleeve rod 34 and the outer sleeve 32 and the elastic buffering effect of the spring 33, the board is uniformly and flexibly pressed at multiple points. It can adaptively fit the thin PCBA board surface and effectively offset the board vibration, slight warping and slippage problems during stamping, providing a stable processing benchmark for subsequent high-precision cutting.

The ion airflow can simultaneously neutralize the static electricity generated by stamping friction, eliminating the problems of static electricity adsorption of dust, damage to precision components and signal interference, and greatly improving the cleanliness of the board surface and the safety of processing. After the pre-forming, cutting, and slag removal processes of the single-station PCBA board are completed, the stamping cylinder 5 retracts and resets, driving the entire stamping and cutting assembly to move vertically upwards, completely separating it from the workpiece processing area, and completing the stamping and reset action. Then, the servo motor 16 starts again, driving the placement turntable 2 to continue indexing and rotating. The processed workpiece rotates synchronously with the turntable, causing the bottom contacting protrusion 18 to gradually approach and contact the lifting bending rod 19 fixed on the top of the bottom support platform 1. Relying on the fixed pushing and limiting action of the lifting bending rod 19, the contacting protrusion 18 is subjected to an upward pushing force, driving the ejector rod 40 and ejector block 11 to slide vertically upwards smoothly along the inner side of the bottom placement plate 12, smoothly ejecting the processed PCBA board out of the groove structure, making it easy for workers or robots to quickly pick up the material. The entire process does not require manual removal of the workpiece, avoiding the risk of bending and scratching the board, and completing a single complete automated processing cycle. The equipment can quickly complete the disassembly and replacement of stamping and cutting components according to the processing requirements of blood glucose meter PCBA boards of different specifications and sizes. During disassembly, manually pull out the locking rod 24 that is inserted into the mounting base 8 and the assembly clip 36 to release the locking limit. Then the assembly clip 36 and assembly plate 38 can be slid out from the assembly slot 1 22 and assembly slot 2 23 respectively, realizing the overall quick disassembly of the stamping and cutting components. When installing new components, align the assembly plate 38 and assembly clip 36 with the corresponding slots for precise engagement and docking to ensure assembly accuracy and coaxiality. Finally, insert the locking rod 24 to lock and fix.
