Description

Technical Field

[0001] The utility model relates to the technical field of coloring rings, in particular to a coloring ring device and a material transfer mechanism thereof. Background Art

[0002] At present, there are many products with color rings, such as parts in the field of electrical connectors, the shanks of grinding heads in the field of abrasive tools, the grinding heads of dental instruments, etc. These products all need to be processed with coloring rings. Taking the field of electrical connectors as an example, the part aviation plug is a common electronic connector, usually used for electrical connections in fields such as aviation, aerospace, military, and industry. The connection method of the aviation plug is a structure with a male head as a part and a female head as a jack. There are different color rings on the parts of the male head. The color rings on the parts are not only a kind of decoration or identification, but also provide intuitive information about the assembly state and tightening degree of the connector to the operator through their colors and positions, thereby improving the safety and reliability of the entire system.

[0003] Most of the color rings on the parts are coated automatically. Automatic feeding is adopted. After feeding, the orientation of the parts needs to be adjusted before unified coating can be carried out. The parts after the orientation is adjusted need to use a material transfer mechanism. Through the material transfer mechanism, the parts after the orientation is adjusted are sent into the part fixing mechanism on the rotating platform for subsequent coloring ring processing. However, most of the existing material transfer mechanisms adopt a mechanical clamping method, such as mechanical jaws. For example, parts such as pins are generally made of copper material, with a relatively soft texture, and their surfaces are generally gold-plated. The mechanical jaws are very likely to deform the parts or damage their surface coatings, resulting in unqualified parts, causing great waste and defective products. Therefore, there is an urgent need for a new part material transfer mechanism to solve the above technical problems. Summary of the Utility Model

[0036] For the convenience of understanding the present utility model, the present utility model will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. The preferred embodiments of the present utility model are given in the accompanying drawings. However, the present utility model 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 content of the present utility model more thorough and comprehensive.

[0037] It should be noted that unless otherwise defined, the technical and scientific terms used in this specification are the same as those generally understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0038] An embodiment of a coloring ring device of the present utility model, as Figures 1 - 12 shown, includes a frame 1, on which a controller, a feeding mechanism 2, a picking and turning mechanism 3, a transfer mechanism 4, a plasma treatment mechanism 5, an ink coating mechanism 6, a heating mechanism 8, a rejection mechanism 7 and a receiving mechanism 9 are provided.

[0039] Specifically, the rack 1 includes a bottom box 11 and a mounting platform 12 disposed on the bottom box. The feeding mechanism 2 and the picking and turning mechanism 3 are disposed on the mounting platform. The feeding mechanism 2 includes a feed bin 21 and a vibrating feeding tray 22. Both the feed bin and the vibrating feeding tray are prior arts, and their structures will not be described in detail in this embodiment. Briefly speaking, parts enter the feed bin and the feed bin timely replenishes the vibrating feeding tray with parts. The vibrating feeding tray can horizontally convey the parts one by one, and one end of the part faces the picking and turning mechanism and is successively conveyed. In this embodiment, the part refers to a product with a long strip shape, a rod shape, or a cylindrical shape.

[0040] The picking and turning mechanism 3, as Figures 2 - 5 shown, includes a mounting frame, a first picking mechanism, and a second picking mechanism. The mounting frame includes a mounting plate 31 fixed to the mounting platform 12, and a first vertical frame 32 and a second vertical frame 33 are disposed on the mounting plate. The first picking mechanism includes a picking head 34 rotatably disposed on the first vertical frame, and a picking head driving device 35 for driving the picking head to rotate is further disposed on the first vertical frame. The picking head driving device uses a pneumatic motor. In other embodiments, a driving motor can also be used. The picking head has a picking head cavity, and both ends of the part can be respectively inserted into the picking head cavity, and the picking head cavity is fitted with the outer peripheral surface of one end of the part for the end of the part to be fitted and inserted, so that the lengths of different ends of the part inserted into the picking head cavity are different. The second picking mechanism includes a part receiving cylinder 38 corresponding to the picking head rotatably disposed on the second vertical frame, and a part receiving cylinder driving device 39 for driving the part receiving cylinder to rotate is disposed on the second vertical frame. The part receiving cylinder driving device uses a pneumatic motor. In other embodiments, a driving motor can also be used. The part receiving cylinder is a through hole and can allow the part to pass through smoothly. Here, "smoothly" means that the part does not flip after horizontally entering and its length direction always generally coincides with the axis direction of the through hole when passing through the through hole. The following "smoothly" is the same as this explanation.

[0041] The picking head has a first working position for the part at one end of the feeding mechanism to enter and a second working position for turning to the part receiving cylinder. In this embodiment, the picking head turns to the horizontal position. At this time, the inlet of the picking head cavity faces the outlet of the vibrating feeding tray, which is the first working position; then it rotates counterclockwise upward by 180 degrees to reach the second working position. The part receiving cylinder has a mounting position for the part at one end of the picking head located at the second working position to enter. The part receiving cylinder also has a forward dropping position for rotating the part receiving cylinder at the mounting position forward by 90 degrees to allow the part at one end to drop downward and a reverse dropping position for rotating the part receiving cylinder at the mounting position backward by 90 degrees to allow the part at one end to drop downward. Here, the forward and reverse correspond to clockwise and counterclockwise. The forward and reverse are not to limit the rotation direction of the part receiving cylinder, but to express that when the part faces different directions, the dropping direction of the part can be adjusted and rotated in two opposite directions.

[0042] The first part picking mechanism further includes a power device for feeding the parts on the part picking head at the second station into the part receiving cylinder at the installation position. In this embodiment, the power device includes an air pipe (not shown in the figure) connected to the part picking head cavity of the part picking head. An air pump is provided on the air pipe. The air pump can suck air or blow air into the part picking head cavity. By sucking air with the air pump, the parts in the part picking head cavity are adsorbed so that the parts are inserted in place and fixed. By the blowing action of the air pump, the parts on the part picking head at the second station are blown into the part receiving cylinder. In other embodiments, the air blowing method may not be adopted, and the pressing method may be adopted. For example, the power device includes a movable ejector rod and an ejector rod driving structure provided on the part picking head, which are used to push the parts on the part picking head at the second station into the part receiving cylinder at the installation position. The ejector rod driving structure can be an electric push rod or a driving cylinder (oil cylinder or air cylinder).

[0043] In order to smoothly feed the parts in the part picking head cavity of the part picking head into the part receiving cylinder, the first vertical frame 32 is set as a movable frame, which can face the second vertical frame so that the part picking head can move closer to the part receiving cylinder. Specifically, the first vertical frame 32 is guided and movably arranged on the mounting plate 31, and a first vertical frame driving cylinder 37 is arranged on the mounting plate, together forming an adjustment mechanism to adjust the distance between the part picking head 34 and the part receiving cylinder 38. A detector 36 for detecting the length of the part inserted into the part picking head cavity to determine the orientation of the part is arranged on the mounting frame. In this embodiment, the detector adopts an infrared sensor and is arranged on the first vertical frame for detecting the parts on the part picking head at the second station. In other embodiments, the detector can also adopt one of a photoelectric sensor, a proximity sensor, and a contact detector (such as a probe). Specifically, when the part picking head and the parts therein are rotated to the second station, as Figure 2 shown, the infrared sensor detects the parts. If the mating end of the part and the part picking head cavity is inserted into the part picking head cavity, the length of the part leaking outside is short, and at this time the infrared sensor cannot detect the part. If the other end of the part is inserted into the part picking head cavity, the length of the part leaking outside is long, and at this time the infrared sensor can detect the part. The orientation of the part is judged according to this inspection method. The detector 36 can be fixed on the first vertical frame, or can be arranged on the first vertical frame through a movable adjustment mechanism that can be adjusted movably in the up and down directions and the orientation direction of the parts on the part picking head at the second station, which can adapt to different models of parts or other products. The above-mentioned movable adjustment mechanisms are all conventional movable adjustment mechanisms and will not be elaborated here. For example, two sets of combined lead screw nut mechanisms, the adjustment direction of one set of lead screw nut mechanisms is arranged horizontally, and the adjustment direction of the other set of lead screw nut mechanisms is arranged in the up and down directions. A receiving cylinder 310 is arranged on the mounting frame, below the outlet of the vibrating feeding tray. The parts that are not taken away by the part picking and turning mechanism in time fall into the receiving cylinder 310 for collection.

[0044] A blanking cylinder 311 is arranged below the part accommodating cylinder on the mounting bracket. The blanking cylinder can allow parts to fall into it from one end and slide down smoothly along that end. The lower end of the blanking cylinder passes through the mounting platform for the material transfer mechanism to transfer the parts. A baffle 312 is arranged on the mounting bracket. As Figure 4 shown, specifically, a baffle 312 is arranged on the second vertical frame 33 to prevent the parts entering the part accommodating cylinder at the mounting position from passing out from the other end. In order to accelerate or enable the parts to smoothly enter the lower blanking cylinder from the part accommodating cylinder, a nozzle mounting block 313 is arranged on the second vertical frame. A nozzle (not shown in the figure) that blows downward is arranged on the nozzle mounting block. The nozzle blows downward. When the part accommodating cylinder rotates to the forward dropping position or the reverse dropping position, the air blowing is directly opposite to the part accommodating cylinder, blowing air into the part accommodating cylinder to accelerate or smoothly enter the parts into the blanking cylinder. A deviation correcting nozzle 314 is arranged at the lower end of the part accommodating cylinder. The deviation correcting nozzle has a flared structure with the large end facing upward. The deviation correcting nozzle also has a discharge cylinder with an inner cavity that matches the size of the part, ensuring accurate part discharge orientation and facilitating the acquisition and transfer by the material transfer mechanism. In other embodiments, when it does not affect the material transfer mechanism to obtain the parts, the deviation correcting nozzle may not be provided.

[0045] A rotating platform 13 is arranged below the mounting platform 12 on the upper box surface of the bottom box, as Figure 10 shown. The rotating platform is driven by a rotating platform driving mechanism to achieve rotation. The rotating platform driving mechanism adopts a motor driving method, and the driving motor and the controller are both located inside the bottom box. A plurality of workstations are arranged at intervals along the circumferential direction on the upper box surface of the bottom box. Part fixing mechanisms corresponding to the above workstations one by one are arranged at intervals along the circumferential direction on 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.

[0046] The structures of the part fixing mechanisms are the same. One of them will be described in detail below: The part fixing mechanism includes a mounting block 14 arranged on the rotating platform 13. A horizontally placed part mounting cylinder 17 is rotatably arranged on the mounting block. The part mounting cylinder has a mounting cavity for the corresponding end of the part to be loaded. The part mounting cylinder is connected with an air pump, and the parts are blown out of the part mounting cylinder by the positive pressure generated by the air pump, or the parts can be adsorbed and fixed by the negative pressure generated by the air pump according to needs. At the material transfer position, the above-mentioned material transfer mechanism 4 is arranged on the mounting platform for transferring the parts dropped from the blanking cylinder into the part mounting cylinder of the corresponding part fixing mechanism, as Figures 6 - 7 and Figure 12As shown. Specifically, the material transfer mechanism includes a mechanism frame 41 fixedly arranged on the installation platform. A horizontally movable block 44 is movably arranged on the mechanism frame. A first driving cylinder 45 for driving the horizontal radial movement of the horizontally movable block 44 is arranged on the mechanism frame. A vertically movable block 46 and a second driving cylinder 47 are arranged on the horizontally movable block. The second driving cylinder is used to drive the up and down movement of the vertically movable block. A fine-tuning mechanism is arranged on the vertically movable block, which can finely adjust the position of the material transfer cylinder in the direction perpendicular to the movement direction of the horizontally movable block. A vertical plate 48 is arranged on the vertically movable block 46. A second moving block 49 is arranged on the vertical plate in a guiding and movable manner along the up and down direction. A vertical adjusting screw 410 threadedly connected to the second moving block is arranged on the vertical plate. The fine-tuning mechanism includes a horizontal plate 411. The horizontal plate 411 is fixedly connected to the second moving block 49. A first moving block 412 is arranged on the horizontal plate in a guiding and horizontally movable manner along the direction perpendicular to the movement direction of the horizontally movable block. A horizontal adjusting screw 413 threadedly connected to the first moving block is arranged on the horizontal plate.

[0047] A material transfer cylinder 43 is rotatably arranged on the first moving block. A material transfer cylinder driving mechanism 42 for driving the rotation of the material transfer cylinder is arranged on the first moving block. The material transfer cylinder driving mechanism adopts a pneumatic motor. The inner cavity of the material transfer cylinder 43 is for the end of the part to fall into. The material transfer cylinder has a blanking position where it rotates to the lower part of the blanking cylinder for one end of the part to fall in, and a feeding position where it rotates to face the part installation cylinder of the part fixing mechanism at this station. A power mechanism for sending out the parts in it to separate from the material transfer cylinder is arranged on the material transfer cylinder. The power mechanism includes an air pipe connected to the inner cavity of the material transfer cylinder 43. An air pump is arranged on the air pipe. The material transfer cylinder can be made to approach the part installation cylinder through the first cylinder, and then the parts in the material transfer cylinder are blown into the part installation cylinder 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 material transfer cylinder. In this embodiment, the suction effect of the air pump can be selected and used according to actual production needs. If the parts do not fall during rotation or movement, the air pump can also not perform adsorption to fix the parts. In other embodiments, the material transfer mechanism can also be arranged on the upper box surface of the bottom box. In other embodiments, the power mechanism includes a movable ejector rod and an ejector rod driving structure arranged on the material transfer cylinder, and the parts are ejected and separated through the movable ejector rod. The ejector rod driving mechanism can adopt a driving cylinder or an electric push rod. In other embodiments, all the air pumps in this embodiment can be replaced by a vacuum generator. 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.

[0048] At the plasma treatment station, a plasma treatment mechanism 5 is provided on the installation platform for surface-treating the parts on the part fixing mechanism transferred to this station, facilitating subsequent ink coating and coloring treatment. The plasma treatment mechanism is a prior art, and its specific structure will not be 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 for rotating the part mounting cylinder and the parts on the part fixing mechanism to ensure plasma treatment of the entire outer peripheral surface of the parts.

[0049] At each ink coating station, an ink coating mechanism 6 is provided on the upper box surface of the bottom box. The ink coating mechanism is used for performing a coloring ring treatment on the parts on the part fixing mechanism transferred thereto. The ink coating mechanism is a prior art, and its specific structure will not be described in detail in this embodiment. Briefly, the ink coating mechanism has an ink cartridge, an ink wheel, and a printing wheel. The ink cartridge is used to store the paint ink of the corresponding color. The ink wheel picks up the paint ink in the ink cartridge, and the printing wheel contacts the ink wheel to stick the paint ink on the ink wheel to the printing wheel. The paint ink is used to color the parts through the printing wheel to perform the coloring ring. To facilitate the coloring ring, the ink coating mechanism can move up and down, and the up and down movement can be achieved through a driving cylinder. For the integrity of the color ring, at each ink coating station, a second part rotating mechanism 61 is provided on the installation platform to drive the part mounting cylinder and the parts on the part fixing mechanism at this station to rotate.

[0050] At the screening and rejection station, the rejection mechanism includes a vision system provided on the installation platform. The vision system includes a vision camera and a processor. A complete picture of the parts with colored rings is pre-stored in the processor. A third part rotating mechanism 72 is provided on the upper box surface of the bottom box for rotating the part mounting cylinder and the parts on the part fixing mechanism to ensure that the vision camera can take a 360-degree shot of the parts and then make a comparison. The rejection mechanism also includes a waste collection pipe 71. The pipe orifice of the waste collection pipe is horizontally arranged and aligned with the part fixing mechanism at this station. When it is found that the parts on the part fixing mechanism at this station are unqualified, the unqualified parts in the part mounting cylinder are blown into the waste collection pipe by blowing air through an air pump connected to the part mounting cylinder of the part fixing mechanism. A waste collection box 73 is provided in the bottom box below the outlet of the waste collection pipe.

[0051] At the heating station, a heating mechanism 8 is arranged on the installation platform to heat the parts with color rings on the part fixing mechanism transferred to this station, so as to quickly dry the color rings on the parts and facilitate the subsequent collection of parts. Currently, when collecting parts with color rings, since the color rings on them are not dry, a special collection board is required. The collection board is provided with a plurality of jacks, and the parts are inserted into the jacks on the collection board one by one through the clamping jaws and placed vertically. This not only makes the collection steps troublesome, but also the structure is relatively complex, the collection board occupies a large area, and it is inconvenient to collect parts. In this embodiment, electromagnetic induction heating is adopted. Specifically, the heating mechanism 8 includes an electromagnetic induction heater 81, for example, high-frequency or ultra-high-frequency can be used. The electromagnetic induction heater includes an induction coil 82. A heater driving mechanism for driving the electromagnetic induction heater is arranged on the machine frame to move the induction coil along the length direction of the part to heat and dry the color ring on the part. The heater driving mechanism includes a third driving cylinder 83 arranged on the machine frame, and the electromagnetic induction heater is arranged on the piston rod of the third driving cylinder to move the induction coil along the length direction of the part. By moving the induction heating coil 82, the induction heating coil moves along the length direction of the part, and the part is located inside the induction heating coil to heat and dry the applied color ring on its surface. In this embodiment, a fixing plate 85 is arranged on the piston rod of the third driving cylinder 83. An active mounting block 86 is arranged on the fixing plate 85 to be guided and moved in the up and down direction. The electromagnetic induction heater is arranged on the active mounting block. An up and down direction adjusting screw 87 for upwardly pressing the active mounting block to adjust the up and down position of the active mounting block is arranged on the fixing plate. In other embodiments, electromagnetic induction heating may not be adopted, but hot air blowing, that is, hot air heating, may be used for heating. For example, the heating mechanism includes a hot air blower, and the air outlet of the hot air blower faces the part. At this time, a part rotating mechanism with the above structure can be arranged at this station to rotate the part, or the part rotating mechanism may not be arranged. In other embodiments, the heating mechanism may also be arranged on the bottom box. In other embodiments, the heating mechanism includes a heat radiation source arranged near the part, and the color ring on the part is heated and dried by relying on the heat radiation method.

[0052] At the material receiving station, the material receiving mechanism includes a material receiving cylinder 91 arranged on the upper box surface of the bottom box. The inlet of the material receiving cylinder is horizontally arranged and faces the part on the part fixing mechanism at this station. By blowing air through an air pump communicated with the part mounting cylinder of the part fixing mechanism at this station, the qualified parts after coloring the color ring are blown into the material receiving cylinder. A part collection box 92 is arranged in the bottom box below the outlet of the material receiving cylinder.

[0053] The structures of the above-mentioned first, second, and third part rotating mechanisms are the same. The following takes one of them as an example for detailed description: As Figure 6As shown in the figure, the part rotating mechanism includes a vertical driving cylinder 511 that moves in the up and 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, and a rubber wheel 513 is provided on the motor shaft. The rubber wheel is used to contact the outer surface of the corresponding part mounting cylinder to drive the part mounting cylinder and the parts inside it to rotate synchronously. The difference lies in the different installation positions. Specifically, the difference is that when in the plasma treatment position and the screening and rejection position, the part rotating mechanism is arranged on the upper box surface of the bottom box; when in the ink coating position, the part rotating mechanism is arranged on the installation platform.

[0054] During use, parts enter the bin in batches and enter the vibrating hopper from the bin. Through the vibrating hopper, the parts are sent horizontally one by one to its outlet. Here, there is a part detection device for detecting parts, which can use a proximity sensor, an optoelectronic sensor, an infrared sensor, a laser sensor, or a vision system to determine whether there are parts at the outlet. When a part is detected, the controller controls the pick-up head to move and / or rotate to the first station for one end of the part to enter the cavity of the pick-up head, and the corresponding air pump sucks air to insert the part in place and adsorb and fix the part. Then, the controller controls the pick-up head driving device to rotate the pick-up head to the second station. When the pick-up head is at the second station, the part is detected by the detector. Since the position of the detector is set, if one end of the part that matches the cavity of the pick-up head is inserted into the pick-up 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 judge the orientation of the part. The controller rotates the part holding cylinder to the installation position through the part holding cylinder driving device, moves the pick-up head towards the part holding cylinder to move closer and align, and after stopping the movement, blows the part into the part holding cylinder through the corresponding air pump. Through the above judgment of the part orientation, it is controlled whether the part holding cylinder rotates 90 degrees forward to the forward dropping position or rotates 90 degrees backward to the forward dropping position. After turning to the position, under the action of gravity, the part freely drops into the blanking cylinder, or the part can also be made to drop smoothly or accelerate into the blanking cylinder by means of air blowing. The transfer cylinder rotates to the blanking position. At this time, the transfer cylinder is directly below the blanking cylinder, and one end of the part dropped from the blanking cylinder can enter the inner cavity of the transfer cylinder. Then, the transfer cylinder driving mechanism rotates the transfer cylinder to the feeding position, moves the transfer cylinder close to the part fixing mechanism at this station, and blows the part out of the transfer cylinder through the power mechanism to send it into the part mounting cylinder of the corresponding part fixing mechanism on the rotating platform. As the rotating platform rotates, the parts are sequentially subjected to surface plasma treatment and ink coating treatment. When the part with the ink coating rotates to the heating position, the third driving cylinder is controlled to drive the induction coil to move along the length direction of the part, and the ink coating on the part is quickly heated by induction heating. Subsequently, the parts can be stacked and collected, which is very convenient to use.

[0055] In the above description of this specification, unless otherwise clearly specified and defined, terms such as "fixed", "installed", "connected" or "coupled" should be understood in a broad sense. For example, with respect to the term "connected", it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the communication inside two components or the interaction relationship between two components. Therefore, unless otherwise clearly defined in this specification, those skilled in the art can understand the specific meanings of the above terms in this utility model according to specific circumstances.

[0056] According to the above description of this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or position relationship such as "upper", "lower", "front", "rear", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "center", "longitudinal", "transverse", "clockwise" or "counterclockwise" are based on the orientation or position relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of this utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or component involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or position relationship cannot be understood or interpreted as a limitation to the solution of this utility model.

[0057] In addition, terms such as "first" or "second" used in this specification to refer to numbers or ordinals are only for descriptive purposes and cannot be understood as explicitly or implicitly indicating relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" or "second" can explicitly or implicitly include at least one such feature. In the description of this specification, the meaning of "a plurality" is at least two, such as two, three or more, etc., unless otherwise clearly and specifically defined.
