Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to a production device for high-frequency and high-speed printed circuits and a process thereof. Background Art

[0002] Printed circuits are electronic circuits manufactured using photolithography, where a copper-clad insulating substrate is etched to form a conductive pattern to connect components. Invented by Austrian engineer Paul Eisler in 1936, the core process draws on printing plate making, using a photochemical method to transfer the circuit pattern to the substrate and remove excess copper foil, replacing traditional manual soldering.

[0003] After searching, the patent application number CN202022383541.0 discloses a workbench for processing printed circuit boards, which belongs to the field of printed circuit board technology. The workbench for processing printed circuit boards includes a base plate, a shock absorber is fixedly connected to the middle part of the upper surface of the base plate, a processing table is fixedly connected to the top of the shock absorber, a slide groove is provided on one side of the upper surface of the processing table, and a clamping member is provided inside the slide groove. The workbench for processing printed circuit boards is provided with a shock absorber, a clamping member and an air cooler. The shock absorber is fixed to the upper surface of the base plate to prevent the device from being damaged by excessive processing force. The clamping member clamps the circuit board for processing. The anti-slip member prevents the circuit board from falling off during processing, thereby increasing protection for the circuit board. The dust dropped during processing enters the dust collection tank below through the through hole, making it convenient to clean the workbench. The air cooler prevents the circuit board from overheating during processing, thereby increasing protection for the personal safety of the staff. The operation is simple and practical.

[0004] However, the above device provides a relatively simple protection structure for the circuit board through the shock absorber, and the processing function of the machine on the circuit board is also relatively simple, which cannot meet the needs of large orders. Summary of the Invention

[0011] Preferably, a clamping hole cooperating with the stretching assembly is provided at the bottom end of the collar rod, and a second limiting groove cooperating with the limiting protrusion is provided on the inner wall of the collar sleeve of the collar rod.

[0012] Preferably, one end of the movable rod is fixedly connected to a second connecting plate, and the second connecting plate is fixedly connected to the first connecting plate through a connecting rod. A first cross-shaped sliding groove is provided on the opposite side of the first connecting plate and the second connecting plate, and a second sliding groove is provided in the first sliding groove. Each of the second sliding grooves is slidably connected to a slide plate, and a sliding sleeve is fixedly connected to one side of the first connecting plate and located at the center of the first sliding groove.

[0019] 2. The first bevel tooth rotates, thereby driving the rotation of several second bevel teeth meshing with it, and then driving the housing to rotate in the collar rod. The first limiting groove and the limiting protrusion cooperate and clamp, so that the collar rod can be adjusted outward or inward while sliding inside the housing, which provides convenience for circuit board processing.

[0020] 3. The electric rotary table drives the next circuit board to perform the above-mentioned processing method. At this point, the processing is completed, and the circuit boards are fixed in batches on the electric rotary table for batch processing. After the circuit board processing is completed, the next circuit board is processed by rotation positioning. The processing process does not require manual adjustment, making the production of circuit boards fully automated. At the same time, the setting of the rubber rod facilitates the resetting of the clamping rod, making the processing accuracy precise and the positioning simple, reducing the investment of manpower and material resources, and effectively improving the processing and positioning efficiency without reducing the accuracy of circuit board processing, thereby further improving production profits.

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] According to the above technical solution, the head end of the circuit board is placed between the circuit board sleeves 316 of the first connecting plate 305, and then the slide rod 310 is moved on the sleeve 309, so that the slide plate 314 connected to the transfer rod 313 expands outward or closes inward along the first slide groove 308, thereby driving the circuit board sleeve 316 connected to it to clamp the head end of the circuit board, and at the same time, the spacing between the two annular claws 319 is adjusted by twisting the screw rod 318, and the annular claws 319 enable the circuit board to remain stable during the movement for processing.

[0034] The first bevel tooth 301 rotates, thereby driving the plurality of second bevel teeth 321 meshing with it to rotate, and further driving the housing 303 to rotate within the collar rod 304. The first limiting groove 3031 is engaged and clamped with the limiting protrusion 3201, so that the collar rod 304 can be adjusted outward or inward while sliding inside the housing 303, which provides convenience for circuit board processing.

[0035] After positioning each circuit board, rotate it in the direction opposite to the power turret 8. The power turret 8 is equipped with multiple processing tools, which can perform processes such as welding and gluing for the circuit board. The cylinder 406 is used to connect the clamping rod 404 with the lower end of the collar rod 304, and the collar rod is driven to move by the screw sleeve, so that the circuit board moves back and forth while rotating, and the cooperation between the second limit groove and the limit protrusion 3201 enables the movable rod to move while rotating.

[0037] In this embodiment, the rotating assembly 3 includes a motor 302, which is fixedly mounted on the cavity 7. The electric rotating table 2 is rotatably connected to the first bevel gear 301 at the center of the circle. The output shaft of the motor 302 extends into the electric rotating table 2 and is fixedly connected to the lower surface of the first bevel gear 301. A plurality of sleeves 303 are provided in the electric rotating table 2. One end of the sleeve 303 is fixedly connected to the second bevel gear 321 and the other end is slidably connected to the movable rod 320. The head end of the circuit board is placed between the circuit board sleeve 316 of the first connecting plate 305, and then the sliding rod 310 is moved on the sliding sleeve 309 to expand the slide 314 connected to the transfer rod 313 outward or close inward along the first sliding groove 308.

[0038] In this embodiment, the first bevel tooth 301 and the second bevel tooth 321 are meshed with each other, and limiting protrusions 3201 are integrated on both sides of the movable rod 320. First limiting grooves 3031 that cooperate with the limiting protrusions 3201 are opened on both sides of the inner wall of the shell 303, thereby driving the circuit board sleeve 316 connected thereto to be clamped with the head end of the circuit board. At the same time, the spacing between the two annular claws 319 is adjusted by twisting the screw rod 318, and the annular claws 319 enable the circuit board to remain stable during processing during the movement.

[0039] In this embodiment, the movable rod 320 extends to the outer surface of the shell 303 and is provided with a collar rod 304. The bottom end of the collar rod 304 extends into the cavity 7. The first bevel tooth 301 rotates, thereby driving the plurality of second bevel teeth 321 engaged with it to rotate, thereby driving the shell 303 and the collar rod 304 to rotate, and the first limiting groove 3031 is cooperated and clamped with the limiting protrusion 3201, so that the collar rod 304 can be adjusted outward or inward while sliding inside the shell 303.

[0040] In this embodiment, a clamping hole cooperating with the stretching component 4 is provided at the bottom end of the collar rod 304, and a second limiting groove 3041 cooperating with the limiting protrusion 3201 is provided on the inner wall of the ring sleeve of the collar rod 304. After each circuit board is positioned, it is rotated in the direction opposite to the power turret 8, and the clamping rod 404 is docked with the lower end of the collar rod 304 through the cylinder 406. The collar rod is driven to move by the screw sleeve, so that the circuit board moves back and forth while rotating.

[0041] When the cam 314 is in the unlock state, the cam 314 is in the unlock state, and the second locking cam 314 is in the unlock state, so that the cam 314 can be unlocked.

[0042] In this embodiment, the sliding sleeve 309 is slidably connected to the sliding rod 310, and the surface of the sliding rod 310 is connected to each slide plate 314 with a transfer rod 313. The sliding rod 310 is equidistantly provided with a number of pin holes 311, and the sliding sleeve 309 is also provided with a pin hole 311. The two opposite pin holes 311 are connected to a pin rod 312, so that the circuit boards are fixed in batches on the electric rotating table 2 for batch processing. After the circuit board processing is completed, the next circuit board is processed by rotation positioning. The processing process does not require manual adjustment, so that the production of the circuit boards is fully automated. At the same time, the setting of the rubber rod facilitates the resetting of the card rod.

[0043] In this embodiment, the slide plate 314 is fixedly connected to the side away from the second connecting plate 306 with a circuit board sleeve 316 that clamps the head end of the circuit board. Two support plates 317 are fixedly connected to the upper surface of the electric rotary table 2 and located at each quadrant point. Each support plate 317 is threadedly connected to a screw rod 318, and the tail end of the screw rod 318 is fixedly connected to an annular claw 319, so that the processing accuracy is accurate and the positioning is simple, which reduces the investment in manpower and material resources. Without reducing the accuracy of circuit board processing, the processing and positioning efficiency is effectively improved, thereby further improving production profits.

[0044] In this embodiment, the stretching assembly 4 includes a second motor 405, which is fixed in the cavity 7. The end of the output shaft of the second motor 405 is fixedly connected to the second screw rod 402, and the rod body of the second screw rod 402 is threadedly connected to the screw rod sleeve 403. The head end of the circuit board is placed between the circuit board sleeve 316 of the first connecting plate 305, and then the slide rod 310 is moved on the sleeve 309, so that the slide plate 314 connected to the transfer rod 313 is expanded outward or closed inward along the first slide groove 308, thereby driving the circuit board sleeve 316 connected to it to clamp with the head end of the circuit board, and at the same time, the spacing between the two annular claws 319 is adjusted by twisting the screw rod 318. The annular claws 319 keep the circuit board stable during the movement for processing.

[0045] The first bevel tooth 301 rotates, thereby driving the plurality of second bevel teeth 321 meshing with it to rotate, and further driving the housing 303 and the collar rod 304 to rotate. The first limiting groove 3031 is engaged and clamped with the limiting protrusion 3201, so that the collar rod 304 can be adjusted outward or inward while sliding inside the housing 303.

[0046] After positioning each circuit board, rotate it in the direction opposite to the power turret 8, and use the cylinder 406 to dock the clamping rod 404 with the lower end of the collar rod 304. The collar rod is driven to move by the screw sleeve, so that the circuit board can be telescopically moved while rotating, and the cooperation between the second limit groove and the limit protrusion 3201 can make the movable rod move while rotating. When the screw sleeve is reset after the circuit board processing is completed, the reset shape of the rubber rod 407 assists the operator in the degree of reset of the screw sleeve. Then the next circuit board is driven by the electric rotary table 2 to perform the above-mentioned processing method, and the processing is completed.

[0047] In this embodiment, the upper surface of the screw sleeve 403 is fixedly connected to the cylinder 406, the top of the piston rod of the cylinder 406 is fixedly connected to the clamping rod 404, the bottom of the cavity 7 is fixedly connected to the connecting plate 401, and a rubber rod 407 is connected between the clamping rod 404 and the connecting plate 401.

[0048] The working principle of the production equipment and process for high-frequency, high-speed printed circuits is as follows: the head end of the circuit board is placed between the circuit board sleeves 316 of the first connecting plate 305 to secure the upper and lower edges of the circuit board. Then, by moving the slide bar 310 on the sleeve 309, the slide plate 314 connected to the transfer rod 313 is expanded outward or closed inward along the first slide groove 308, thereby driving the connected circuit board sleeve 316 to clamp the upper and lower edges of the circuit board. At the same time, by twisting the screw rod 318 to adjust the spacing between the two annular claws 319, the left and right edges of the circuit board are clamped. The annular claws 319 ensure that the circuit board remains stable during the movement and processing. The purpose of the annular claws 319 is to achieve a double-annular symmetrical structure to achieve uniform radial force and avoid single-point stress concentration. In particular, for multi-layer PCBs, it can prevent microcracks or damage to the inner layer circuits caused by local extrusion. The material of its annular clamping claw 319 is elastic. This structure disperses pressure through composite elastomers to improve clamping stability. Through preliminary positioning of the upper and lower sides (the slide rod mechanism bears about 80% of the pre-tightening force) and secondary fine-tuning of the left and right sides (the screw system implements fine locking), a gradient force mode is formed to avoid instantaneous impact that may cause BGA solder joint cracking. The measured stress peak value is reduced by 42%, which has a protective effect during the circuit board processing process.

[0049] The first bevel tooth 301 rotates, thereby driving the plurality of second bevel teeth 321 meshing with it to rotate, and further driving the housing 303 to rotate within the collar rod 304. The first limiting groove 3031 is engaged and clamped with the limiting protrusion 3201, so that the collar rod 304 can be adjusted outward or inward while sliding inside the housing 303, which provides convenience for circuit board processing.

[0050] After positioning each circuit board, rotate it in the direction opposite to the power turret 8. The power turret 8 is equipped with multiple processing tools, which can perform processes such as welding and gluing for the circuit board. The cylinder 406 is used to connect the clamping rod 404 with the lower end of the collar rod 304, and the collar rod is driven to move by the screw sleeve, so that the circuit board moves back and forth while rotating, and the cooperation between the second limit groove and the limit protrusion 3201 enables the movable rod to move while rotating. When the screw sleeve is reset after the circuit board processing is completed, the reset shape of the rubber rod 407 assists the operator in the degree of reset of the screw sleeve. Then the electric rotary table 2 is used to drive the next circuit board to perform the above-mentioned processing method, and the processing is completed.

[0051] The circuit boards are fixed in batches on the electric rotary table 2 for batch processing. After the circuit board processing is completed, the next circuit board is processed by rotation positioning. The processing process does not require manual adjustment, making the production of circuit boards fully automated. At the same time, the setting of the rubber rod facilitates the resetting of the clamping rod, making the processing accuracy precise and the positioning simple, reducing the investment in manpower and material resources, and effectively improving the processing and positioning efficiency without reducing the accuracy of the circuit board processing, thereby further improving the production profit.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
