Description

Technical Field

[0001] The invention relates to the technical field of automated processing, in particular to a device for removing gold-plated layers from pins. Background Art

[0002] The pin of the electrical connector is a key component of the electrical connector, which is mainly used for the transmission of electrical signals. At present, grinding or electro-corrosion is used to remove the local gold-plated layer. The grinding method for removing the gold-plated layer has low production efficiency, and the heavy metal dust generated has a greater impact on the health of the operator. It is not suitable for batch production and has low production efficiency. The electro-corrosion method has the disadvantage of not being fine enough and easily causing batch failures. In addition, the assembly and positioning of the material pins during the production process is more difficult, the equipment development cost is high, heavy metal wastewater will be generated, the environmental protection is poor, the site requirements are high and the versatility is poor. Summary of the invention

[0003] The purpose to be achieved by the present invention is to provide a device for removing the gold plating layer of the pin, which solves the problems of low efficiency and environmental pollution in the prior art of removing the gold plating layer of the pin, improves production efficiency, optimizes production quality, and is more environmentally friendly.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a device for removing the gold plating layer of a pin, comprising a frame, on which a loading mechanism, a laser cleaning module, a multi-station circulation module, a processing station and an upper and lower material station are provided, the processing station and the upper and lower material stations are respectively provided with a rotating mechanism, the laser cleaning module is used to remove the gold plating layer of the pin at the processing station, the loading mechanism is used to rotate the pin onto the rotating mechanism, the rotating mechanism is used to drive the pin to rotate so that the laser cleaning module removes the gold plating layer of the pin circumferentially, the multi-station circulation module is used to drive the rotating mechanism of the processing station and the rotating mechanism of the upper and lower material stations to exchange positions, and while the upper and lower material stations load and unload the pin, the processing station removes the gold plating layer of the pin.

[0005] After adopting the above technical scheme, the present invention has the following advantages: first, laser cleaning can act on the target area more accurately, which helps to ensure that the entire surface of the pin is evenly processed, improving the consistency of product quality. The laser de-plating process produces almost no harmful emissions, which is more environmentally friendly and safe. In addition, by rotating the pin, the laser cleaning module can remove the surface of the pin more comprehensively, ensuring that the gold-plated layer on the entire circumference is evenly removed as much as possible, thereby avoiding as much as possible the situation where some areas are not processed or unevenly processed due to fixed-angle processing. Secondly, loading and unloading operations are carried out simultaneously during product processing, making full use of the time during product processing, loading and unloading are carried out while processing, so that the pin gold-plated layer removal equipment can work continuously, greatly improving work efficiency.

[0006] Furthermore, the multi-station circulation module includes a linear rail and a push-pull cylinder, and the adjacent processing stations and at least two rotating mechanisms on the upper and lower material positions are fixedly connected, and the push-pull cylinder is used to pull the at least two rotating mechanisms to move synchronously.

[0007] With the above technical solution, since the processing station and the loading and unloading station can perform different operations at the same time, that is, when one station is processing, another station can complete loading or unloading, this parallel processing method greatly shortens the processing time of a single part and improves the overall efficiency of the production line. By controlling the switching of the rotating mechanism between different stations through mechanized push-pull cylinders, the entire process can be highly automated, reducing manual intervention and further improving production efficiency.

[0008] Furthermore, the frame is provided with at least two laser cleaning modules, at least two processing stations and at least two loading and unloading stations.

[0009] By adopting the aforementioned technical solution, the design of multiple laser cleaning modules and processing stations enables the system to process multiple pins in parallel, further improving production efficiency.

[0010] Furthermore, the rotating mechanism includes a first motor, a base and a rotating shaft, the rotating shaft is rotatably arranged on the base, the output end of the first motor is fixedly connected to the rotating shaft, and the rotating shaft is provided with an elastic member, an unlocking member, and a first clamping portion and a second clamping portion arranged opposite to each other, the first clamping portion and the second clamping portion are in a clamping state in which they are approached to each other by the elastic force of the elastic member to clamp the insertion pin, and are in a feeding state in which they are pulled by the unlocking member to overcome the elastic force of the elastic member and separated from each other to release the insertion pin. When the first clamping portion and the second clamping portion are in the clamping state, the first motor drives the rotating shaft to rotate relative to the base.

[0011] By adopting the above-mentioned technical solution, the first clamping part and the second clamping part are moved closer to each other due to the elastic force of the elastic part, and the pin can be automatically clamped in a natural state without the need for additional manual operation. The presence of the unlocking part allows the clamping state to be quickly released when needed, which facilitates the automation of the loading and unloading process of the pin and improves production efficiency.

[0012] Furthermore, the unlocking member includes a first telescope and a push block arranged at the output end of the first telescope, the first clamping part is provided with a connecting rod passing through the second clamping part, and the end of the connecting rod passing through the second clamping part is provided with a top block, the elastic member is arranged on the connecting rod and contacts with the top block and the second clamping part, and the push block is used to push the top block to separate the first clamping part and the second clamping part.

[0013] Through the above technical solution, the first telescopic device usually has a faster response speed, and can complete the separation action of the first clamping part and the second clamping part in a short time, thereby increasing the speed of loading and unloading, and thus improving the efficiency of the entire production line.

[0014] Furthermore, the base body includes a first blowing component for blowing the pin between the first clamping portion and the second clamping portion.

[0015] Through the above technical solution, after the pin is processed, the first blowing component can provide additional force to help push the pin out of the first clamping part and the second clamping part, thereby ensuring that the pin can be smoothly removed from the device as much as possible to reduce jamming.

[0016] Furthermore, an air inlet is provided in the radial direction of the rotating shaft, the first blowing component is connected to the air inlet, an air outlet connected to the air inlet is provided in the axial direction of the rotating shaft, and pins are arranged relatively between the air outlet and the first clamping part and the second clamping part.

[0017] Through the above technical solution, the gas enters the interior of the rotating shaft radially and then is ejected through the axial air outlet, thereby forming a more concentrated and directional airflow. It can also facilitate the installation of the first blowing component, and the air outlet is directly aligned with the surface of the pin, so that the airflow can act on the pin more concentratedly and effectively.

[0018] Furthermore, the laser cleaning module includes a mounting frame, a laser generator and a second retractor, and the laser generator is arranged at the output end of the second retractor.

[0019] Through the above technical solution, the distance between the laser generator and the pin can be accurately controlled through the second telescope, ensuring that the laser beam can accurately act on the area where the gold plating layer needs to be removed, which helps to improve processing accuracy and consistency.

[0020] Furthermore, the feeding mechanism includes a second blowing component, a pressing block, a third telescope and a feeding platform, the feeding platform is provided with a material trough for placing the pins, the second blowing component is used to blow the pins into the material trough, the pressing block and the output end of the third telescope are connected and located above the material trough, the third telescope drives the pressing block to have a first position close to the material trough to clamp the pin and a second position away from the material trough to release the pin.

[0021] Through the above technical solution, through the action of the second blowing component, the pins that are closely arranged or plugged together can be blown away and separated, ensuring that each pin can enter the material trough individually. The pins are blown into the material trough through the second blowing component, thereby realizing an automated loading process, reducing the need for manual intervention and improving production efficiency.

[0047] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0048] like Figures 1 to 10 As shown, the present invention provides a device for removing the gold plating layer of a pin, comprising a frame 10, on which a loading mechanism 20, a laser cleaning module 30, a multi-station circulation module 40, a processing station 11 and an upper and lower material station 12 are provided. The processing station 11 and the upper and lower material station 12 are respectively provided with a rotating mechanism 50, the laser cleaning module 30 is used to remove the gold plating layer of a pin 60 of the processing station 11, the loading mechanism 20 is used to rotate the pin 60 onto the rotating mechanism 50, the rotating mechanism 50 is used to drive the pin 60 to rotate so that the laser cleaning module 30 circumferentially removes the gold plating layer of the pin 60, the loading mechanism 20 is used to feed the pin 60 upward, the multi-station circulation module 40 is used to drive the rotating mechanism 50 of the processing station 11 and the rotating mechanism 50 of the upper and lower material station 12 to exchange positions, and while the upper and lower material stations 12 load and unload the pin 60, the processing station 11 removes the gold plating layer of the pin 60.

[0049] First, laser cleaning can act more accurately on the target area, which helps to ensure that the entire surface of the pin 60 is evenly treated, improving the consistency of product quality. The laser de-plating process produces almost no harmful emissions, which is more environmentally friendly and safe. In addition, by rotating the pin 60, the laser cleaning module 30 can remove the surface of the pin 60 more comprehensively, ensuring that the gold plating layer on the entire circumference is removed evenly as much as possible, thereby avoiding as much as possible the situation where some areas are not treated or unevenly treated due to fixed-angle treatment. Secondly, loading and unloading operations are carried out simultaneously during the product processing process, making full use of the time during the product processing process, loading and unloading are carried out while processing, so that the pin gold plating removal equipment can work continuously, greatly improving work efficiency.

[0050] In order to further improve work efficiency, the frame 10 is provided with at least two laser cleaning modules 30, at least two processing stations 11 and at least two upper and lower material stations 12. The design of multiple laser cleaning modules 30 and processing stations 11 enables the system to process multiple pins 60 in parallel, further improving production efficiency.

[0051] Preferably, two laser cleaning modules 30 , two processing stations 11 and two upper and lower material positions 12 are provided on the frame 10 , and the two laser cleaning modules 30 are respectively provided corresponding to the two processing stations 11 .

[0052] Specifically, the laser removal module 30 includes a mounting frame 31, a laser generator 32 and a second retractor 33, wherein the laser generator 32 is disposed at the output end of the second retractor 33. Through the second retractor 33, the distance between the laser generator 32 and the pin 60 can be precisely controlled to ensure that the laser beam can accurately act on the area where the gold plating layer needs to be removed, which helps to improve processing accuracy and consistency.

[0053] In order to realize feeding, the feeding mechanism 20 is mainly divided into a material distribution part and a transfer part. The material distribution part includes a feeding vibration disk 21, a second blowing component 22, a pressing block 23, a third telescope 24, a fourth telescope 25, a material baffle plate 26, a feeding detection laser 27 and a feeding platform 28. The feeding platform 28 is provided with a material trough 281 for placing the insertion pin 60. The feeding vibration disk 21 is located at one end of the material trough 281. The second blowing component 22 is used to blow the insertion pin 60 into the material trough 281. The output ends of the pressing block 23 and the third telescope 24 are connected and located above the material trough 281. The third telescope 24 drives the pressing block 23 to have a first position close to the material trough 281 to clamp the insertion pin 60 and a second position away from the material trough 281 to release the insertion pin 60. The fourth telescope 25 is used to drive the material baffle plate 26 to rise and fall. The material baffle plate 26 is located at the discharge end of the slide. The second blowing component 22 can blow and separate the closely arranged or plugged together pins 60, ensuring that each pin 60 can enter the material trough 281 individually. The pins 60 are blown into the material trough 281 by the second blowing component 22, thereby realizing an automated loading process, reducing the need for manual intervention and improving production efficiency.

[0054] The transfer part includes a clamping claw 291, a transverse slide rail 292 and a longitudinal slide rail 293 slidably connected to the transverse slide rail 292. The clamping claw 291 is connected to the longitudinal slide rail 293. The longitudinal slide rail 293 is provided with a longitudinal driver 294 for driving the clamping claw 291 to slide longitudinally on the longitudinal slide rail 293. The transverse slide rail 292 is provided with a transverse driver 295 for driving the longitudinal slide rail 293 to slide transversely on the transverse slide rail 292. The clamping claw 291 is used to grab the pin 60 on the material trough 281 and transfer it to the rotating mechanism 50.

[0055] The design of the transverse slide rail 292 and the longitudinal slide rail 293 enables the gripping claw 291 to move freely in two directions, increasing its flexibility and adaptability. This multi-directional movement capability can handle troughs 281 and rotating mechanisms 50 in different positions and layouts, ensuring that the pins 60 are transferred to the rotating mechanism 50 as accurately as possible.

[0056] In order to realize the processing, the multi-station circulation module 40 includes a linear rail 41 and a push-pull cylinder 42. The two rotating mechanisms 50 on the adjacent processing stations 11 and the upper and lower material stations 12 are fixedly connected. The push-pull cylinder 42 is used to pull at least two rotating mechanisms 50 to move synchronously. By controlling the switching of the rotating mechanisms 50 between different stations through the mechanized push-pull cylinder 42, the whole process can be highly automated, reducing manual intervention and further improving production efficiency.

[0057] In addition, the rotating mechanism 50 includes a first motor 51, a base 52, a positioning code disk 53, a coupling 54 and a rotating shaft 55. The rotating shaft 55 is rotatably arranged on the base 52. The output end of the first motor 51 is fixedly connected to the rotating shaft 55. The rotating shaft 55 is provided with an elastic member 573, an unlocking member, and a first clamping portion 57 and a second clamping portion 58 that are relatively arranged. The first clamping portion 57 and the second clamping portion 58 have a clamping state in which they are approached to each other by the elastic force of the elastic member 573 to clamp the insertion pin 60, and a feeding state in which they are pulled by the unlocking member to overcome the elastic force of the elastic member 573 and separated from each other to release the insertion pin 60. When the first clamping portion 57 and the second clamping portion 58 are in the clamping state, the first motor 51 drives the rotating shaft 55 to rotate relative to the base 52. The first clamping portion 57 and the second clamping portion 58 are connected by an elastic member 573, and can automatically clamp the pin 60 in a natural state without additional manual operation. The presence of the unlocking member allows the clamping state to be quickly released when needed, facilitating the automation of the loading and unloading process of the pin 60 and improving production efficiency.

[0058] Among them, the unlocking member includes a first retractor 591 and a push block 592 arranged at the output end of the first retractor 591, the first clamping part 57 is provided with a connecting rod 571 passing through the second clamping part 58, and one end of the connecting rod 571 passing through the second clamping part 58 is provided with a top block 572, and the elastic member 573 is arranged on the connecting rod 571 and contacts with the top block 572 and the second clamping part 58. When the first retractor 591 drives the push block 592 to move toward the top block 572, the push block 592 first abuts against the top block 572 and pushes the top block 572 in the subsequent movement process to separate the first clamping part 57 and the second clamping part 58. After the first retractor 591 drives the push block 592 to move away from the top block 572, the push block 592 is separated from the top block 572. At this time, the first clamping portion 57 approaches the second clamping portion 58 under the restoring force of the elastic member 573 and maintains a clamping state with the second clamping portion 58. Since the push block 592 is separated from the top block 572, the top block 572 and the push block 592 are prevented from interfering when the rotating mechanism 50 drives the pin 60 to rotate. The first retractor 591 usually has a fast response speed and can complete the separation of the first clamping portion 57 and the second clamping portion 58 in a short time, thereby increasing the speed of loading and unloading, and thus improving the efficiency of the entire production line.

[0059] It should be noted that the output end of the first motor 51 is fixedly connected to the rotating shaft 55 through the coupling 54 and the positioning code disk 53, and the pushing block 592 and the top block 572 are parallel through the positioning code disk 53.

[0060] In order to reduce the jamming of the plug pin 60 during blanking, the base 52 is provided with a first blowing component 56 for blowing the plug pin 60 between the first clamping portion 57 and the second clamping portion 58. After the plug pin 60 is processed, the first blowing component 56 can provide additional force to help push the plug pin 60 out of the first clamping portion 57 and the second clamping portion 58, thereby ensuring that the plug pin 60 can be smoothly removed from the device and reduce jamming.

[0061] The rotating shaft 55 includes a first mounting step 551, a second mounting step 552, a radial locking thread 554, a third mounting step 553, a sealing groove 555, an air inlet 556, a positioning step 557, and an air outlet 558. The first blowing component 56 is connected to the air outlet 558 through the air inlet 556, and the pin 60 is relatively arranged between the first clamping part 57 and the second clamping part 58, wherein the air inlet 556 and the air outlet 558 are connected at 90 degrees. The gas enters the interior of the rotating shaft 55 radially and then is ejected through the axial air outlet 558, which can form a more concentrated and directional airflow, and can also facilitate the installation of the first blowing component 56. The air outlet 558 is directly aligned with the surface of the pin 60, so that the airflow can act on the pin 60 more concentratedly and effectively. The first mounting step 551 is used for positioning the installation of the coupling 54, the second mounting step 552 is used for positioning the installation of the positioning code disk 53, the rotating shaft 55 is installed on the base 52 through the bearing, the third mounting step 553 is used for positioning the installation of the bearing, and the positioning step 557 is used to position the first clamping part 57 and the second clamping part 58.

[0062] It should be noted that the air inlet 556 and the air outlet 558 may also be connected at an angle of 80 degrees or 60 degrees.

[0063] In order to collect the pins 60 after unloading, the frame 10 is also provided with an unloading detection laser 43 and a unloading collection hopper 44. The unloading detection laser 43 is used to detect whether there are pins 60 between the first clamping part 57 and the second clamping part 58. The unloading collection hopper 44 is located below the first clamping part 57 and the second clamping part 58 and is used to collect the pins 60.

[0064] In order to further reduce environmental pollution, a smoking device is also provided on the frame 10 to purify the smoke generated during production and make the equipment production more environmentally friendly.

[0065] In order to further reduce environmental pollution, the outer cover of the frame 10 is provided with a protective cover 13, and the protective cover 13 is provided with a touch control screen 14 and a display screen 15. The touch control screen 14 is used to control the processing of the pin 60, and the display screen 15 is used to display the processing status of the pin 60.

[0066] When in use, the second blowing component 22 uses gas to blow the pin 60 forward in the material slot 281. When the feeding detection laser 27 detects that there is material, the third retractor 24 pulls the pressing block 23 down to press the pin 60. The fourth retractor 25 descends to make the baffle plate 26 leave the discharge end of the chute. The clamping claw 291 moves to the material taking position, the clamping claw 291 clamps the pin 60, the third retractor 24 pushes and pulls the pressing block 23 to rise, and the longitudinal driver 294 drives the clamping claw 291 to move in the longitudinal direction. After the slide rail 293 is retracted by one stroke, the third retractor 24 pulls the pressure block 23 down again to press the next pin 60, and the clamping claw 291 retracts on the longitudinal slide rail 293. The fourth retractor 25 drives the baffle plate 26 to rise, so that the baffle plate 26 is located at the discharge end of the slide slot to prevent the pin 60 in the slide slot from moving out of the slide slot. The third retractor 24 pushes the pressure block 23 to rise, and the second blowing component 22 blows another pin 60 over, completing the pin 60 feeding and separation action, and entering the next cycle. After the laser cleaning module 30 removes the gold-plated layer of the pin 60 of the processing station 11, the push-pull cylinder 42 pushes and pulls all the rotating mechanisms 50 to move synchronously to switch the position of the pin 60. When the gold plating layer of the pin 60 is removed, since the push block 592 and the top block 572 may be misaligned, the first motor 51 rotates, and the push block 592 and the top block 572 are aligned through the positioning code disk 53, the air inlet 556 of the rotating shaft 55 and the first blowing component 56 are connected, the first retractor 591 drives the push block 592 to move, so that the elastic member 573 is compressed, and then the first clamping part 57 and the second clamping part 58 are opened, and the first blowing component 56 is controlled to make the compressed gas enter from the air inlet 556 of the rotating shaft 55 and come out from the air outlet 558, thereby blowing the pin 60 off the first clamping part 57 and the second clamping part 58. When the material unloading detection laser 43 detects that there is no material, the first blowing component 56 stops blowing, and the clamping claw 291 takes another pin 60 from the material slot 281 and puts it between the first clamping part 57 and the second clamping part 58. The first retractor 591 drives the push block 592 to reset, and the first clamping part 57 and the second clamping part 58 are in a clamping state to clamp the pin 60. The clamping claw 291 is released and retracted to complete the loading; the push-pull cylinder 42 pushes the rotating mechanism 50 that has completed the loading to the processing station 11, and the first motor 51 rotates to cooperate with the laser generator 32 to start the rotation processing. At the same time, the rotating mechanism 50 that has completed the processing of the pin 60 returns to the unloading position to complete the cycle.

[0067] It should be noted that the first retractor 591 , the second retractor 33 , the third retractor 24 and the fourth retractor 25 may be cylinders, the elastic member 573 may be a spring, and the first blowing component 56 and the second blowing component 22 may be air pumps.
