Description

Technical Field

[0001] The invention relates to the technical field of PCB processing equipment, and more specifically, to a drill needle color coating ring mechanism. Background Art

[0002] In the PCB manufacturing industry, the drilling process is to process the PCB substrate according to the hole positions designed by the customer for use in subsequent processes. After the drilling process, old drill bits that need to be reground will be produced. To control the number of times the old drill bits are reground, different colors need to be painted on the shoulder of the drill bits for grinding control.

[0003] It involves marking the drill bit with color. Considering that coloring on the drill blade affects the accuracy, coloring on the drill shank affects the clamping accuracy of the machine tool, and the tail part of the drill bit needs to be coded, only the shoulder of the drill bit is left for color marking.

[0004] The general operation method is to place the drill bit with the blade facing upwards in the cutter disc, and use a paint pen to paint the shoulders of the drill bit in rows. The process is inefficient, and there is a risk of work-related injuries if the hand is close to the blade facing upwards. There is a risk of damage to the drill bit if the drill bit with a diameter of 0.35 to 0.15 is touched by the paint pen.

[0005] The existing invention patent application number is CN202410045966.0, which discloses a gripping device and a drill bit batch coloring device formed by it, including: a gripping assembly, including a gripping drive and a first gripping plate and a second gripping plate located in the same plane, the first gripping plate is provided with a plurality of first card slots, the second gripping plate is provided with second card slots corresponding to the first card slots one by one, the gripping drive is connected to the first gripping plate and / or the second gripping plate, when the first gripping plate and the second gripping plate are molded under the drive of the gripping drive, the first card slot and the second card slot form a clamping ring for clamping the workpiece; a driving assembly connected to the gripping assembly is used to drive the gripping assembly to move toward or away from the workpiece.

[0006] Ink coloring refers to using different colors to represent the number of times the drill bit is polished to control its lifespan. Usually, the drill bit needs to be coated with ink multiple times, and each time the ink is coated, the color applied last time needs to be covered. When the above-mentioned coloring device is coloring, it is difficult to control the amount of ink used, and its coating effect is poor, and it is difficult to completely cover the color applied last time, so there is still room for improvement. Summary of the invention

[0007] In view of the deficiencies in the prior art, the object of the present invention is to provide a drill needle color coating ring mechanism to solve the above technical problems.

[0008] The above technical purpose of the present invention is achieved through the following technical scheme: a drill bit coloring ring mechanism, comprising: a fixed seat, on which a transport assembly is arranged; a drill bit rotation assembly is arranged on the fixed seat; a coloring assembly is rotatably arranged on the fixed seat; a push rod assembly is arranged on the fixed seat, and the output end of the push rod assembly is rotatably connected to the coloring assembly.

[0009] Specifically, a jig for carrying drill bits is pre-set, and the drill bits are arranged in a row on the jig, and the drill bits can rotate on the jig. When painting the drill bits, the drill bits of the same grinding are first placed on the jig, and then the jig is placed on the transport assembly, and the jig is transported by the transport assembly. When the drill bit moves to the position of the drill bit rotating assembly, the drill bit rotating assembly drives the drill bit to rotate, and the push rod assembly pushes the painting assembly close to the shoulder of the drill bit, and ink is applied to the shoulder of the drill bit in the rotating state.

[0010] The transport component is a conveyor belt, which transports the jig to move the drill bit to a corresponding position.

[0011] The drill needle is carried by a jig, and the drill needle rotating assembly is used to drive the drill needle to rotate. The push rod assembly pushes the painting assembly close to the shoulder of the drill needle. The drill needle can be evenly painted while rotating, thereby completely covering the color applied last time, to ensure the painting effect of the drill needle.

[0012] Optionally, the coloring component includes: an ink cartridge, which is rotatably arranged on the fixed seat; a coloring motor is arranged in the ink cartridge; a coloring belt group is arranged at the output end of the coloring motor; an ink pad is arranged in the ink cartridge; the ink pad abuts against the coloring belt group; and the output end of the push rod assembly is rotatably connected to the ink cartridge.

[0013] When the drill needle is painted, the push rod assembly pushes the ink cartridge to make the painting belt group contact the shoulder of the drill needle, and the painting belt group is driven to rotate by the painting motor. Since the painting belt group abuts against the ink pad, the painting belt group can absorb the ink on the ink pad, and the painting belt group rotates in the opposite direction to the drill needle, with the same angular velocity. After the painting belt group contacts the drill needle, the ink on the painting belt group can be applied to the shoulder of the drill needle without affecting the rotation of the drill needle, so that the ink is evenly applied to the shoulder of the drill needle.

[0014] When the drill needle is not painted, the push rod assembly pulls the ink cartridge to reset the painting belt group. At this time, the painting belt group does not contact the drill needle, and the painting motor drives the painting belt group to rotate slowly to prevent the ink on the painting belt group from drying and solidifying.

[0015] Optionally, the coloring belt group includes: a coloring drive wheel, a cotton core belt and a coloring roller; the coloring drive wheel is fixed to the output end of the coloring motor; the cotton core belt is sleeved on the coloring drive wheel and the coloring roller; the coloring roller is rotatably set on the ink cartridge; the cotton core belt is in contact with the ink pad.

[0016] Specifically, the coloring motor drives the coloring driving wheel to rotate, which drives the cotton core belt to rotate. After the cotton core belt contacts the ink pad, it absorbs ink from the ink pad, and after the coloring roller contacts the shoulder of the drill needle, the ink on the cotton core belt is applied to the shoulder of the drill needle.

[0017] Optionally, an ink squeezing wheel is arranged in the ink cartridge; an ink squeezing gap is formed between the ink squeezing wheel and the coloring driving wheel; and the cotton core belt is arranged in the ink squeezing gap.

[0018] By setting an ink squeezing wheel, the cotton core belt can be squeezed after absorbing ink from the ink pad to control the amount of ink on the cotton core belt, avoid the cotton core belt from taking out too much ink, and ensure the amount of ink coated on the drill needle.

[0019] Optionally, a coloring shaft is arranged on the fixing seat; a coloring sleeve is arranged on the ink cartridge; and the coloring sleeve is slidably connected to the coloring shaft.

[0020] When the drill needle needs to be painted, the push rod assembly pushes the ink cartridge, and the ink cartridge rotates around the connection between the paint sleeve and the paint shaft, so that the cotton core belt contacts the drill needle. When the drill needle does not need to be painted, the push rod assembly pulls the ink cartridge, and the ink cartridge rotates around the connection between the paint sleeve and the paint shaft, so that the cotton core belt separates from the drill needle.

[0021] Optionally, the push rod assembly includes: an electromagnetic push rod; the electromagnetic push rod is arranged on the fixed seat; a connecting ring is arranged at the output end of the electromagnetic push rod; a connecting rod is arranged on the ink cartridge; and the connecting rod is slidably connected to the connecting ring.

[0022] When the drill needle is to be painted, the electromagnetic push rod pushes the connecting collar, so that the connecting collar drives the connecting rod to move toward the drill needle. At this time, the ink cartridge rotates around the coloring shaft and drives the cotton core belt close to the drill needle, so that the shoulder of the drill needle can be painted. When the drill needle is not to be painted, the electromagnetic push rod is in a normally closed state, the connecting collar is retracted, and drives the connecting rod to move away from the drill needle, driving the cotton core belt away from the shoulder of the drill needle.

[0023] Since different colors are needed to represent the grinding times of the drill bit to control the life span, the ink cartridge needs to be replaced to coat the drill bit with the corresponding color. The ink cartridge can be easily separated from the fixing seat by slidingly connecting the color-coated rotating shaft with the color-coated shaft sleeve, and the ink cartridge can be easily separated from the connecting ring by slidingly connecting the connecting ring with the connecting rod, thereby realizing the replacement of the ink cartridge.

[0024] Optionally, the drill bit rotation assembly includes: a driving seat, on which a driving motor is arranged; a driving belt group is arranged at the output end of the driving motor; and the driving seat is arranged on the fixed seat.

[0025] The driving motor drives the driving belt group to rotate, and makes the driving belt group contact with the drill needle to drive the drill needle to rotate, wherein the driving belt group and the coloring belt group rotate in the same direction.

[0026] Optionally, a driving shaft is arranged on the fixing seat; a driving shaft sleeve is arranged on the driving seat; and the driving shaft is slidably connected to the driving shaft sleeve.

[0027] The driving seat can be rotated on the fixed seat by driving the rotating shaft and the driving sleeve, so that the angle of the driving seat can be adjusted, and the driving belt group can contact the drill needle and drive the drill needle to rotate.

[0028] Optionally, a stretching assembly is also provided on the driving seat; the stretching assembly includes a stretching spring, and a pull rod is provided on the driving seat; a fixing rod is provided on the fixing seat; one end of the stretching spring is fixed to the pull rod, and the other end is fixed to the fixing rod.

[0029] The tension spring applies tension to the pull rod, so that the driving belt assembly is kept in a position in contact with the drill needle, thereby ensuring the rotation of the drill needle.

[0030] Optionally, a limit baffle is provided on the fixing seat.

[0031] The limit baffle can limit the position of the jig, thereby ensuring that the drill needle on the jig can always contact with the driving belt group, and when the electromagnetic push rod is pushed out, the cotton core belt can contact with the shoulder of the drill needle.

[0032] In summary, the present invention has the following beneficial effects:

[0033] The drill needle is carried by the jig, and the drill needle rotating assembly drives the drill needle to rotate, and the push rod assembly pushes the painting assembly close to the shoulder of the drill needle, so that the drill needle can be painted evenly on the shoulder of the drill needle while rotating, thereby completely covering the color applied last time, so as to ensure the painting effect of the drill needle;

[0034] The ink cartridge can be easily separated from the fixing seat by the sliding connection between the coloring shaft and the coloring sleeve, and the ink cartridge can be easily separated from the connecting ring by the sliding connection between the connecting ring and the connecting rod, thereby realizing the replacement of the ink cartridge.

[0090] When the drill needle 16 is to be painted, the electromagnetic push rod 51 pushes the connecting collar 52, so that the connecting collar 52 drives the connecting rod 9 to move toward the drill needle 16. At this time, the ink cartridge 41 rotates around the painting shaft 7 and drives the cotton core belt 432 close to the drill needle 16, so that the shoulder of the drill needle 16 can be painted. When the drill needle 16 is not to be painted, the electromagnetic push rod 51 is in a normally closed state, the connecting collar 52 is retracted, and drives the connecting rod 9 to move away from the drill needle 16, driving the cotton core belt 432 away from the shoulder of the drill needle 16.

[0091] Since different colors are needed to represent the grinding times and life control of the drill needle 16, the ink cartridge 41 needs to be replaced to coat the drill needle 16 with the corresponding color. The ink cartridge 41 can be easily separated from the fixing seat 1 by slidingly connecting the coloring shaft 7 and the coloring sleeve 8, and the ink cartridge 41 can be easily separated from the connecting collar 52 by slidingly connecting the connecting rod 9, thereby realizing the replacement of the ink cartridge 41.

[0096] Optionally, a stretching assembly is also provided on the driving seat 31; the stretching assembly includes a stretching spring, and a pull rod 12 is provided on the driving seat 31; a fixing rod 13 is provided on the fixing seat 1; one end of the stretching spring is fixed to the pull rod 12, and the other end is fixed to the fixing rod 13.

[0097] The tension spring applies tension to the pull rod 12 , so that the driving belt set 33 is kept in a position in contact with the drill needle 16 , thereby ensuring the rotation of the drill needle 16 .

[0098] Optionally, a limit stopper 14 is provided on the fixing seat 1 .

[0099] The limit baffle 14 can limit the position of the jig 15, thereby ensuring that the drill needle 16 on the jig 15 can always contact the driving belt set 33, and when the electromagnetic push rod 51 is pushed out, the cotton core belt 432 can contact the shoulder of the drill needle 16.

[0100] The drill needle coloring ring mechanism of the present application is highly efficient and labor-saving, and the automatic coloring does not require manpower; it can accurately and evenly apply the color ring to the shoulder of the drill needle 16 and can cover the previous coloring; the position of the drill needle 16 is limited by the fixture 15 and the limit baffle 14, and the coloring component 4 and the drill needle rotating component 3 both avoid the blade of the drill needle 16, which can prevent the blade of the drill needle 16 from being damaged; when the drill needle 16 is not colored, the coloring motor 42 slowly rotates the coloring belt group 43 in the standby state, so that the cotton core belt 432 is continuously moistened to prevent the ink on the coloring belt group 43 from drying and solidifying.
