Description
Technical Field
[0001] The invention relates to the technical field of parts coloring rings, and in particular to a coloring ring device and a material picking and turning mechanism thereof. Background Art
[0002] At present, there are many products with color rings, such as parts in the field of electrical connectors, handles of grinding heads in the field of abrasives and grinding tools, grinding heads of dental equipment, etc. These products all need to be coated with color rings. Taking the field of electrical connectors as an example, the aviation plug is a common electronic connector, which is usually used for electrical connections in the fields of aviation, aerospace, military, industry, etc. The connection method of the aviation plug is a structure in which the male head is a part and the female head is a jack. There are different color rings on the parts of the male head. The color ring on the part is not only a decoration or identification, but also provides intuitive information about the assembly status and tightening degree of the connector to the operator through its color and position, thereby improving the safety and reliability of the entire system.
[0003] The coloring rings on the above-mentioned products are mostly processed by automated coloring and automatic loading, but the orientation of the parts needs to be adjusted in order to color them uniformly. Most of the existing ones use a visual system in conjunction with a steering mechanism. The visual system uses a visual camera to take pictures of the parts, and identifies and compares the images of the parts stored in the background. The steering mechanism mostly uses a clamping mechanical structure to adjust the direction. The cost of the visual system in this mechanism for adjusting the direction of the parts is relatively high, and the parts, especially aviation parts, are mostly made of high-quality copper materials and gold-plated on the surface. The clamping steering mechanism can easily clamp the surface of the parts, which can easily cause defects or even unqualified products. Therefore, there is an urgent need for a new material picking and steering mechanism to solve the above technical problems. Summary of the invention

[0042] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0043] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0044] An embodiment of a coloring ring device of the present invention, as Figure 1-Figure 12 As shown, it includes a frame 1, on which are arranged a controller, a feeding mechanism 2, a material picking and turning mechanism 3, a material transfer mechanism 4, a plasma processing mechanism 5, an inking mechanism 6, a heating mechanism 8, a rejecting mechanism 7 and a material receiving mechanism 9.
[0045] Specifically, the frame 1 includes a bottom box 11 and a mounting platform 12 arranged on the bottom box. The feeding mechanism 2 and the material picking and steering mechanism 3 are arranged on the mounting platform. The feeding mechanism 2 includes a silo 21 and a vibrating feeding tray 22. Both the silo and the vibrating feeding tray are prior art, and their structures are no longer described in detail in this embodiment. In short, the parts enter the silo and the vibrating feeding tray is replenished with parts in time through the silo. The parts can be transported out horizontally one by one through the vibrating feeding tray, and one end of the parts is transported toward the material picking and steering mechanism. In this embodiment, the parts refer to products with a long strip, rod-like or cylindrical shape.
[0046] Picking material turning mechanism 3, such as Figure 2-5 As shown, it includes a mounting frame, a first material picking mechanism and a second material picking mechanism. The mounting frame includes a mounting plate 31 fixed on the mounting platform 12, and a first vertical frame 32 and a second vertical frame 33 are arranged on the mounting plate. The first material picking mechanism includes a material picking head 34 rotatably arranged on the first vertical frame, and a material picking head driving device 35 for driving the material picking head to rotate is also arranged on the first vertical frame. The material picking head driving device adopts a pneumatic motor. In other embodiments, a driving motor can also be adopted. The material picking head has a material picking head cavity, and the material picking head cavity can be respectively inserted into the two ends of the part, and the material picking head cavity is matched with the outer peripheral surface of one end of the part for the end of the part to be matched and inserted, so that different ends of the part are inserted into the material picking head cavity The length is different. The second material picking mechanism includes a part accommodating cylinder 38 rotatably arranged on the second vertical frame and corresponding to the material picking head. A part accommodating cylinder driving device 39 for driving the part accommodating cylinder to rotate is arranged on the second vertical frame. The part accommodating cylinder driving device adopts a pneumatic motor. In other embodiments, a driving motor can also be adopted. The part accommodating tube is a through hole and can allow the parts to pass freely in the forward direction. The "forward direction" here means that the part does not flip over after entering horizontally, and its length direction is always roughly consistent with the axial direction of the through hole through the through hole. The following "forward direction" is equivalent to this explanation.
[0047] The picking head has a first station for one end of the part on the feeding mechanism to enter and a second station for the part accommodating cylinder. In this embodiment, the picking head is rotated to a horizontal position, and the inlet of the picking head cavity faces the discharge port of the vibrating feeding tray, which is the first station; then it rotates 180 degrees counterclockwise upward to reach the second station. The part accommodating cylinder has an installation position for one end of the part on the picking head located at the second station to enter, and the part accommodating cylinder also has a forward dropping position for rotating the part accommodating cylinder of the installation position 90 degrees forward for one end of the part to fall downward and a reverse dropping position for rotating the part accommodating cylinder of the installation position 90 degrees reversely for one end of the part to fall downward. The forward and reverse directions here correspond to clockwise and counterclockwise. The forward and reverse directions are not intended to limit the rotation direction of the part accommodating cylinder, but to express that when the parts are facing different directions, the falling direction of the parts can be adjusted and rotated in two opposite directions.
[0048] The first material picking mechanism also includes a power device for delivering the parts on the material picking head of the second station into the part receiving tube of the installation position. In this embodiment, the power device includes an air pipe (not shown in the figure) connected to the material picking head cavity of the material picking head, and an air pump is provided on the air pipe. The air pump can either evacuate air or blow air into the material picking head cavity. The air pump evacuates the parts in the material picking head cavity so that the parts are inserted into place and fixed. The air pump blows the parts on the material picking head at the second station into the part receiving tube. In other embodiments, the air blowing method may not be used, and the top pressure method may be used. For example, the power device includes a movable push rod and a push rod driving structure provided on the material picking head, which are used to push the parts on the material picking head at the second station into the part receiving tube at the installation position. The push rod driving structure may be an electric push rod or a driving cylinder (oil cylinder or air cylinder).
[0049] In order to be able to smoothly deliver the parts in the picking head cavity of the picking head into the parts accommodating cylinder, the first vertical frame 32 is set as a movable frame, which can be oriented toward the second vertical frame so that the picking head can move closer to the parts accommodating cylinder. Specifically, the first vertical frame 32 is guided and movably arranged on the mounting plate 31, and the mounting plate is provided with a first vertical frame driving cylinder 37, which together form an adjustment mechanism to adjust the distance between the picking head 34 and the parts accommodating cylinder 38. The mounting frame is provided with a detector 36 for detecting the length of the part inserted into the picking head cavity to determine the direction of the part. In this embodiment, the detector adopts an infrared sensor and is arranged on the first vertical frame, which is used to detect the parts on the picking head located at the second station. In other embodiments, the detector can also be one of a photoelectric sensor, a proximity sensor, and a contact detector (such as a probe). Specifically, when the picking head and the parts therein are transferred to the second station, such as Figure 2 As shown, the infrared sensor detects the parts. If the matching end of the part and the picking head cavity is inserted into the picking head cavity, the length of the leaked part is short. At this time, the infrared sensor cannot detect the part. If the other end of the part is inserted into the picking head cavity, the length of the leaked part is long. At this time, the infrared sensor can detect the part. The orientation of the part is determined according to this inspection method. The detector 36 can be fixed on the first vertical frame, or it can be set on the first vertical frame through an active adjustment mechanism that can be adjusted along the up and down directions and the orientation direction of the part on the picking head at the second station. It can adapt to different models of parts or other products. The above-mentioned active adjustment mechanisms are all conventional active adjustment mechanisms, which will not be described in detail here. For example, two sets of screw nut mechanisms are combined together, one set of screw nut mechanisms has an adjustment direction set horizontally, and the other set of screw nut mechanisms has an adjustment direction set up in the up and down direction. A receiving barrel 310 is set on the mounting frame, which is set below the exit of the vibrating loading tray. Parts that are not taken away by the picking steering mechanism in time fall into the receiving barrel 310 for collection.
[0050] A blanking barrel 311 is provided on the mounting frame below the part receiving barrel. The blanking barrel can allow parts to fall into it from one end and slide down along the end. The lower end of the blanking barrel passes through the mounting platform for the transfer mechanism to transfer the parts. A baffle 312 is provided on the mounting frame. Figure 4 As shown, specifically, a baffle 312 is provided on the second vertical frame 33 to prevent the parts entering the part holding tube located in the installation position from passing out from the other end. In order to accelerate or enable the parts to smoothly enter the blanking tube below from the part holding tube, an air nozzle mounting block 313 is provided on the second vertical frame, and an air nozzle for blowing air downward (not shown in the figure) is provided on the air nozzle mounting block. The air nozzle blows air downward. When the part holding tube is turned to the forward dropping position or the reverse dropping position, the air blows directly to the part holding tube, and blows air into the part holding tube, so that the parts are accelerated or smoothly enter the blanking tube. A deviation correction nozzle 314 is provided at the lower end of the part holding tube. The deviation correction nozzle has a trumpet structure with the large end facing upward. The deviation correction nozzle also has a discharge tube whose inner cavity matches the size of the part, ensuring that the part discharge direction is accurate and convenient for the transfer mechanism to obtain and transfer. In other embodiments, the deviation correction nozzle may not be provided when it does not affect the transfer mechanism to obtain the part.
[0051] A rotating platform 13 is provided on the upper box surface of the bottom box below the mounting platform 12. Fig.10 As shown, the rotating platform is driven by a rotating platform driving mechanism to achieve rotation. The rotating platform driving mechanism is driven by a motor, and the driving motor and the controller are both located in the bottom box. A plurality of workstations are arranged at intervals along the circumference of the upper box surface of the bottom box, and a part fixing mechanism corresponding to the above-mentioned workstations is arranged at intervals along the circumference of the upper surface of the rotating platform 13. In this embodiment, the number of workstations and the number of part fixing mechanisms are both 8, and the rotating platform rotates one workstation each time. In this embodiment, the 8 workstations are respectively a material transfer position, a plasma treatment position, three ink coating positions, a screening and rejection position, a heating position, and a material receiving position. In other embodiments, the number of workstations can also be adjusted according to actual needs, for example, the number of ink coating positions is adjusted according to the number of color rings to be coated.
[0052] The structures of the various parts fixing mechanisms are the same, and one of them is described in detail below as an example: the parts fixing mechanism includes a mounting block 14 disposed on a rotating platform 13, on which a horizontally placed parts mounting cylinder 17 is rotatably disposed, and the parts mounting cylinder has a mounting cavity for the corresponding end of the part to be loaded, and the parts mounting cylinder is connected to an air pump, and the parts are blown out of the parts mounting cylinder by the positive pressure generated by the air pump, and the parts can also be adsorbed and fixed by the negative pressure generated by the air pump as needed. At the material transfer position, the above-mentioned material transfer mechanism 4 is disposed on the mounting platform, which is used to transfer the parts dropped from the blanking cylinder to the corresponding parts mounting cylinder of the parts fixing mechanism, such as Figure 6-7 and Fig.12As shown. Specifically, the material transfer mechanism includes a mechanism frame 41 fixedly arranged on the mounting platform, a horizontal movable block 44 is movably arranged on the mechanism frame, a first driving cylinder 45 is arranged on the mechanism frame for driving the horizontal movable block 44 to move horizontally and radially, a vertical movable block 46 and a second driving cylinder 47 are arranged on the horizontal movable block, and the second driving cylinder is used to drive the vertical movable block to move up and down.

A vertical plate 48 is arranged on the vertical movable block 46, a second movable block 49 is arranged on the vertical plate for guiding movement in the up and down directions, and a vertical adjustment screw 410 is arranged on the vertical plate for threading with the second movable block.

[0053] A rotating barrel 43 is rotatably arranged on the first moving block, and a rotating barrel driving mechanism 42 for driving the rotating barrel to rotate is arranged on the first moving block, and the rotating barrel driving mechanism adopts a pneumatic motor. The inner cavity of the rotating barrel 43 is for one end of the part to fall into. The rotating barrel has a blanking position that rotates to the bottom of the blanking barrel for one end of the part to fall into, and a feeding position that rotates to the part installation barrel facing the part fixing mechanism of the station. The rotating barrel is provided with a power mechanism for sending the parts inside it out to separate from the rotating barrel, and the power mechanism includes an air pipe connected to the inner cavity of the rotating barrel 43, and an air pump is arranged on the air pipe. The rotating barrel can be brought close to the part installation barrel through the first cylinder, and then the parts in the rotating barrel are blown into the part installation barrel by the blowing of the air pump. At the same time, the suction effect of the suction pump can firmly adsorb the parts in the rotating barrel. The suction effect of the air pump in this embodiment can be selected and used according to the actual production needs. If the parts do not fall during the rotation or movement process, the air pump can also fix the parts without adsorption. In other embodiments, the material transfer mechanism may also be arranged on the upper box surface of the bottom box. In other embodiments, the power mechanism includes a movable ejector and an ejector drive structure arranged on the material transfer barrel, and the parts are ejected and separated by the movable ejector, and the ejector drive mechanism may adopt a drive cylinder or an electric push rod. In other embodiments, all the air pumps in this embodiment may be replaced by a vacuum generator, and the parts are blown out by the positive pressure generated by the vacuum generator, and the parts are adsorbed and fixed by the negative pressure generated by the vacuum generator.
[0054] At the plasma treatment position, a plasma treatment mechanism 5 is provided on the mounting platform, which is used to perform surface treatment on the parts on the part fixing mechanism transferred to the station, so as to facilitate the subsequent ink coating and coloring treatment. The plasma treatment mechanism is a prior art, and its specific structure is not described in detail in this embodiment. At this station, a first part rotating mechanism 51 is provided on the upper box surface of the bottom box, which is used to rotate the part mounting cylinder and the parts on the part fixing mechanism, so as to ensure that the entire outer peripheral surface of the part is subjected to plasma treatment.
[0055] At each ink coating position, an ink coating mechanism 6 is provided on the upper box surface of the bottom box, and the ink coating mechanism is used to perform color ring processing on the parts on the part fixing mechanism transferred to this position. The ink coating mechanism is a prior art, and its specific structure is not described in detail in this embodiment. In short, the ink coating mechanism has an ink cartridge, an ink wheel and a printing wheel. The ink cartridge is used to store paint ink of corresponding colors. The ink wheel brings up the paint ink in the ink cartridge. The printing wheel contacts the ink wheel and sticks the paint ink on the ink wheel to the printing wheel. The parts are colored by the paint ink through the printing wheel to perform color ring coating. In order to facilitate the color ring coating, the ink coating mechanism can move up and down, and the up and down movement can be achieved by a driving cylinder. For the integrity of the color ring, at each ink coating position, a second part rotating mechanism 61 is provided on the mounting platform to drive the part mounting cylinder and the parts on the part fixing mechanism at the station to rotate.

A waste collection box 73 is arranged below the outlet of the waste collection pipe in the bottom box.
[0057] At the heating position, a heating mechanism 8 is arranged on the mounting platform to heat the parts with color rings on the parts fixing mechanism transferred to the station, so as to realize the rapid drying of the color rings on the parts, and facilitate the subsequent collection of parts. At present, when collecting the parts with color rings, since the color rings on them are not dry, a special collecting plate is required, and a plurality of jacks are arranged on the collecting plate. The parts are inserted into the jacks on the collecting plate one by one through the clamps, and placed vertically. Not only the collecting steps are troublesome, but also the structure is relatively complicated. The collecting plate occupies a large area, and the collection of parts is inconvenient. In this embodiment, the heating adopts electromagnetic induction heating. Specifically, the heating mechanism 8 includes an electromagnetic induction heater 81, for example, a high frequency or ultra-high frequency can be adopted.

[0058] At the receiving position, the receiving mechanism includes a receiving barrel 91 arranged on the upper box surface of the bottom box. The inlet of the receiving barrel is arranged horizontally and faces the parts on the part fixing mechanism of the station. The air pump connected to the part installation barrel of the part fixing mechanism of the station blows the qualified color-coated parts into the receiving barrel. A parts collection box 92 is arranged below the outlet of the receiving barrel in the bottom box.
[0059] The structures of the first, second and third parts rotating mechanisms are the same, and one of them is taken as an example for detailed description below: Figure 6As shown, the part rotating mechanism includes a vertical driving cylinder 511 that moves in the up-down direction, a driving block is provided at the moving end of the vertical driving cylinder, a motor 512 is provided on the driving block, a rubber wheel 513 is provided on the motor shaft, and the rubber wheel is used to contact the outer surface of the corresponding part installation cylinder to drive the part installation cylinder and the parts inside to rotate synchronously. The difference lies in the different installation positions, specifically: in the plasma treatment position and the screening and rejection position, the part rotating mechanism is set on the upper box surface of the bottom box; in the ink coating position, the part rotating mechanism is set on the installation platform.
[0060] When in use, parts enter the silo in batches, and then enter the vibrating loading tray from the silo. The parts are sent horizontally to the outlet of the vibrating loading tray one by one. A part detection device for detecting parts is set here. A proximity sensor, photoelectric sensor, infrared sensor, laser sensor or visual system can be used to determine whether there are parts at the outlet. When the presence of the part is detected, the controller controls the picking head to move and / or rotate to the first station for one end of the part to enter the cavity of the picking head, and the corresponding air pump is used to suck air to insert the part into place and adsorb and fix the part, and then the picking head driving device is controlled to realize the rotation of the picking head and transfer to the second station. When the picking head is at the second station, the detector detects the part. Since the position of the detector is set, if one end of the part that matches the cavity of the picking head is inserted into the picking head, the detector cannot detect the part at this time. On the contrary, if the length of the part leaking out is longer, the detector can detect the part, so as to determine the direction of the part. The controller rotates the part holding cylinder to the installation position through the part holding cylinder driving device, moves the picking head toward the part holding cylinder and moves close to the alignment, and blows the part into the part holding cylinder through the corresponding air pump after stopping the movement. By judging the orientation of the above parts, it is controlled whether the part holding cylinder is rotated 90 degrees forward to the forward drop position or 90 degrees reverse to the forward drop position. After being rotated to the position, the part falls freely into the blanking cylinder under the action of gravity, or the part can be smoothly or accelerated to fall into the blanking cylinder by air blowing. The rotating barrel rotates to the blanking position. At this time, the rotating barrel is located directly below the blanking barrel, and one end of the part dropped from the blanking barrel can enter the inner cavity of the rotating barrel. Then, the rotating barrel driving mechanism rotates the rotating barrel to the feeding position, moves the rotating barrel close to the part fixing mechanism of the station, and blows the part out of the rotating barrel through the power mechanism to send it to the part installation barrel of the corresponding part fixing mechanism on the rotating platform. As the rotating platform rotates, the parts are subjected to surface plasma treatment and ink color ring treatment in turn. When the parts coated with the color ring are transferred to the heating position, the third driving cylinder is controlled to drive the induction coil to move along the length direction of the parts, and the color ring on the parts is quickly heated by induction heating. The parts can be subsequently stacked and collected, which is very convenient to use.
