Technical Field

[0001] The present invention relates to the field of electroplating, and in particular to an automatic drying method, system, storage medium and terminal for electroplated products. Background Art

[0002] Electroplating is a process that uses electrochemical principles to plate a layer of metal or alloy on a metal or non-metal surface. During electroplating, the metal parts are fixed on a conductive hanger and then immersed in an electrolyte solution for electroplating. After the electroplating is completed, the metal parts are removed from the solution for cleaning, drying and necessary subsequent treatment.

[0003] When drying metal parts, most factories usually hang the metal parts on a hanger to drain some of the liquid first, and then use a handheld blower to dry the metal parts. Due to the complex structure of metal parts, manual drying of each hole of the metal product is required, which is inefficient. Summary of the invention

[0081] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0082] The embodiment of the present application discloses an automatic drying method for electroplated products. After the metal product is electroplated, the product is hung on a hanger, and a transmission device drives the hanger to move a drying box along a track. In the drying box, the product is moved to a vibration position, a rotation position, and a blow-drying position in sequence, and is respectively subjected to vibration drying, rotation drying, and blow-drying to remove liquid from the product.

[0083] Reference Figure 1 , a method for automatic drying of electroplated products comprises the following steps:

[0084] Step S100: Acquire product image information, and retrieve product models from a preset product database according to the product image information.

[0085] The product image information here is an image of the product acquired by a camera when the product moves to the drying position.

[0086] The product database is a database generated by technicians based on the company's products, including parameter information of all the company's products, which will not be described here. Comparing the product image information with the product database can determine the product model corresponding to the product to be dried.

[0087] Step S101: determining hole position and hole angle information according to product image information and product model.

[0088] The hole position refers to the position of the hole on the product surface. The hole angle information refers to the angle between the center axis of the hole and the product hanging axis. After determining the product model, the hole position and hole angle information can be directly obtained based on the product model and product image information.

[0089] Step S102: determining a preset blowing angle of the blowing device according to the hole angle information.

[0090] The product is dried mainly by an air blowing device at the drying position, and the air blowing device has a blowing nozzle for blowing air.

[0091] When the hole position of the product is blown dry by the air blowing device, the air blowing device needs to be aligned with the hole position of the product first, so the air blowing angle of the air blowing device needs to be adjusted. The air blowing angle is consistent with the hole angle information, so the air blowing angle of the air blowing device can be determined by the hole angle information.

[0092] Step S103: controlling a preset ultrasonic device to release sound waves to the hole position and obtain hole echo information.

[0093] The ultrasonic device is arranged on the blowing device to detect the type of holes, which include through holes and blind holes, wherein the through holes penetrate the product, while the blind holes do not penetrate. The ultrasonic device releases sound waves to the hole position, and then receives the reflected sound wave information. The hole echo information is the reflected sound wave information.

[0094] Step S104: determining whether the hole is a through hole or a blind hole according to whether the hole echo information falls within a preset reference echo range.

[0095] The reference echo range is a reference range set by technicians as a basis for determining the hole type. If the hole echo information falls within the reference echo range, it means that the reflected sound wave is received, and the hole position is a blind hole. If the hole echo information does not fall within the reference echo range, it means that after the ultrasonic device releases the sound wave to the hole position, the sound wave directly passes through the hole, and no or only a very small amount of sound wave is emitted, so the hole is a through hole.

[0096] Step S105: Based on the through hole, determine the hole contour information according to the product image information and the hole position, and determine the inner wall line of the hole low point according to the hole contour information.

[0097] In the case where the hole is a through hole, the hole contour information can be obtained by image analysis of the hole position in the product image information. The image analysis method is a prior art and will not be described here. The hole contour information is the shape contour of the hole on the surface of the product. In this embodiment, both the blind hole and the through hole are columnar structures.

[0098] The inner wall line of the lowest point of the hole refers to the line path of the lowest point of the inner wall of the hole when the product is hung. The lowest point position of the hole can be obtained from the hole contour information, and the inner wall line of the lowest point of the hole can be determined on the inner wall of the hole according to the lowest point position.

[0099] Step S106: Limit the product by limiting the product shaking method, control the blowing device to adjust the angle and width according to the blowing angle and the preset minimum wide angle, control the blowing device to blow along the hole contour information to blow the liquid to the inner wall line of the low point of the hole, and control the blowing device to move along the inner wall line of the low point of the hole to blow the liquid out from the other end of the hole.

[0100] When blowing air into the holes, the product needs to be fixed first so that when the blowing device blows air into the holes, the product is not easy to shake and blow off. The product is limited by the product shaking limiting method, which will not be described here, but will be described in detail in the subsequent embodiments.

[0101] The minimum wide angle is a reference value set by the technicians. When the nozzle of the blowing device blows at the minimum wide angle, the airflow is more concentrated.

[0102] After the hole is limited, the angle and width of the blowing device are adjusted first, and then the blowing device is controlled to blow along the hole contour information and parallel to the axis of the hole, and the liquid is blown onto the inner wall line of the low point of the hole. At this time, the blowing device is controlled to blow along the inner wall line of the low point of the hole from one end of the hole to the other end. During the blowing process, the angle of the blowing device is continuously adjusted to blow the liquid out from the other end of the hole.

[0103] Step S107: Based on the blind hole, hole contour information is determined according to the product image information and the hole position, and the low point blowing position is determined according to the hole contour information.

[0104] In the case where the hole is a blind hole, the hole contour information can be obtained by image analysis of the hole position in the product image information. The image analysis method is a prior art and will not be described in detail here. The low point blowing position is the lowest point position in the hole contour information. The low point blowing position can be determined based on the hole contour information. By blowing the low point blowing position through the blowing device, the air can bounce off the inner bottom surface in the blind hole and leave the blind hole from the high point position of the blind hole and take away the liquid.

[0105] Step S108: determining the hole depth according to the hole echo information, and determining the blowing force of the blowing device on the blind hole according to the hole depth.

[0106] The hole depth is the depth of the blind hole. The hole depth can be obtained by analyzing the hole echo information. The specific analysis method is an existing technology and will not be described here. Due to the different hole depths, the blowing force of the blowing device to blow the liquid attached to the blind hole out of the blind hole will also be different. The blowing force of the blowing device can be matched according to the hole depth.

[0107] Step S109: limit the product position by limiting the product shaking method, control the blowing device to adjust the angle and the wide angle according to the blowing angle and the preset minimum wide angle, and control the blowing device to blow the hole position at the low point blowing position according to the blowing force.

[0108] Compared with step S106, the difference is that when blowing air into the blind hole, air is blown directly at the low point of the blind hole, and the blowing device does not need to move. At this time, the rebounded air can take away the liquid.

[0109] Reference Figure 2 , the product shaking limiting method includes the following steps:

[0110] In this embodiment, when the air blowing device is used to blow air into the holes of the product, the top blowing device is used to blow air on the back of the product to offset the force applied by the air blowing device to the holes, thereby making the product less likely to shake.

[0111] Step S200: determining a top position directly opposite to the hole position on the back of the product according to the hole position.

[0112] The top position refers to the position on the back of the product corresponding to the point where the blowing device directly blows the air on the front of the product. This position is on the axis of the hole. The top position on the back of the product can be determined by the hole position on the front of the product.

[0113] Step S201: determining a restricted area within a preset extended distance on both sides of the top position according to the product image information.

[0114] Blowing on the back side by only one top blowing device has poor stability, so two top blowing devices are used to blow air at the same time, and the blowing positions of the top blowing devices are at both sides of the top position.

[0115] The extended distance is a reference value set by the technicians, and is used to determine the blowing positions for the two top blowing devices to blow simultaneously on both sides of the top position, which will not be described in detail here. The restricted area is the position for the top blowing device to blow. The restricted area can be determined by horizontally extending the extended distance on both sides of the top position.

[0116] Step S202: determining the preset top-to-top blowing force of the top-to-top blowing device for the restricted area according to the blowing force of the blowing device for blowing the hole position.

[0117] When the two restricted areas are determined, there is an air blowing device around the product for drying and two top air blowing devices for limiting and fixing the product. The three air blowing devices are located at the three corners of the product, and the top air blowing devices are symmetrically arranged relative to the top positions. Therefore, when the blowing force of the air blowing device for drying is determined, the top air blowing force of the top air blowing device can also be calculated according to the blowing force of the air blowing device.

[0118] Step S203: When the blowing device blows air to the hole position, the top blowing device is controlled to blow air to the restricted area with the top blowing force.

[0119] When the blowing position and blowing force of the blowing device as well as the limiting position and blowing force of the top blowing device are determined, the product can be blown dry.

[0120] Reference Figure 3 The liquid in the holes on the surface of the product can be blown dry by blowing air at the holes through a blowing device, while the liquid on the surface of the product needs to be blown dry by another method. The product surface drying method includes the following steps:

[0121] Step S300: obtaining the blowing distance between the product and a preset blowing device.

[0122] The blowing distance is the distance between the product surface and the blowing nozzle of the blowing device when the product is in the blowing position.

[0123] Step S301: Query and obtain surface profile parameters according to product image information and product model.

[0124] By comparing the product image information with the product database, the product model corresponding to the product to be dried can be determined, and the surface profile parameters can be queried from the parameter database of the product according to the product model. The surface profile parameters refer to the outermost contour surface of the product.

[0125] Step S302: determining the projection area of ​​the product in the direction of the blowing device according to the surface profile parameters.

[0126] The projection area refers to the surface projection of the product facing the side of the blowing device and can be directly blown by the blowing device. The outer contour lines in various directions can be determined by the surface profile parameters, and the projection area can be determined based on the outer contour lines.

[0127] Step S303: determining the blowing area range according to the blowing distance and the preset blowing wide angle of the blowing device.

[0128] The blowing area range refers to the area range that can be effectively blown by the blowing device within a certain distance of the blowing device. The blowing area range is the range covered by a cone, so the blowing area range can be calculated by combining the blowing distance between the product and the blowing device and the blowing angle of the blowing nozzle of the blowing nozzle device. The specific solution method is the existing technology and will not be repeated here.

[0129] Step S304: determining direct blowing or distance adjustment according to whether the projection area falls within the blowing area range.

[0130] In order to ensure that the surface of the product facing the blowing device can be blown by the blowing device, the projected area of ​​the product needs to fall within the blowing area range of the blowing device, that is, the projected area of ​​the product should be smaller than the blowing area range. The subsequent drying steps of the product are determined by judging whether the projected area falls within the blowing area range.

[0131] If the projected area falls within the blowing area range, it means that the surface of the product facing the blowing device can be blown by the blowing device, and the product can be blown directly by the blowing device.

[0132] If the projected area does not fall within the blowing area, it means that the product is too large and part of the product surface cannot be directly blown by the blowing device. At this time, the distance between the product and the blowing device can be adjusted.

[0133] Step S305: Based on direct blowing, the blowing device is controlled to blow air to the entire product and the product is driven to rotate by wind force to perform circumferential blowing.

[0134] When the projected area falls within the blowing area range, the blowing device is directly controlled to blow air, and the product is driven to rotate by wind during the blowing process, so that the surface of the product can be dried in the circumferential direction during the rotation process.

[0135] Step S306: Based on the distance adjustment, determine the projection excess value according to the projection area and the blowing area range, and match the distance adjustment value of the blowing device according to the projection excess value.

[0136] The projection excess value refers to the area of ​​the projection area that does not fall within the blowing area range and cannot be blown by the blowing device. The projection excess value is the difference between the projection area and the blowing area range.

[0137] The distance adjustment value is the distance that the blowing device is moved. The blowing area range is expanded by increasing the blowing distance, so that the projection area falls within the blowing area range.

[0138] The distance adjustment value is proportional to the projection excess value in a one-to-one correspondence. The larger the projection excess value, the larger the distance adjustment value. Therefore, the distance adjustment value can be determined by the projection excess value.

[0139] Step S307: controlling the blowing device to increase the blowing distance according to the distance adjustment value, and controlling the blowing device to blow air to the entire product and drive the product to rotate by wind force to perform circumferential blowing.

[0140] After the blowing distance is adjusted so that the product facing the side of the blowing device can be completely blown, the subsequent process is the same as step S305 and will not be described in detail here.

[0141] In this embodiment, in addition to moving the blowing device to expand the blowing area, the blowing angle of the blowing nozzle may also be increased.

[0142] Reference Figure 4 , before the product is blown dry by the blowing device at the drying position, the following steps are included:

[0143] Step S400: obtaining the hanging weight information of the product hung on the preset hanger.

[0144] The electroplating line has a transmission track for drying work, and the hanger is slidably installed on the transmission track for hanging the electroplated products. After the product is electroplated, it needs to be hung on the hanger to automatically carry out the subsequent drying process. The hanging weight information refers to the weight of the product. Different hanging weight information corresponds to different products. A tension sensor is set on the hanger to obtain the hanging weight information.

[0145] Step S401: Determine product suspension based on the comparison between the suspension weight information and a preset reference weight.

[0146] The reference weight is used to measure whether there are products hanging on the hanger. It is a reference value set by technicians and will not be described here. When the hanging weight information is greater than the reference weight, it means that there are products hanging on the hanger and the subsequent drying process can be carried out. If the hanging weight information is not greater than the reference weight, it means that there are no electroplated products on the hanger at this time.

[0147] Step S402: Based on the product hanging, control the preset transmission device to start to drive the product to move into the preset drying box, and obtain the transmission path image information in real time.

[0148] The conveying device is used to drive the hanger and the product to move on the conveying track so as to send the product into the drying box for drying. The drying box is used to dry the product.

[0149] The transmission path image information is an image on the transmission path acquired by a camera arranged on the drying work line. When the product moves to a specific drying position, an image of the product will be included in the transmission path image information.

[0150] Step S403: judging from a preset vibration position database whether the product has moved to a preset vibration position according to the transmission path image information.

[0151] The vibration position database is a database obtained through training of a neural network model, which contains images of the product when it moves to the vibration position. It is a prior art and will not be described in detail here.

[0152] By comparing the transmission path image information with the vibration position database, if the transmission path image matches the data in the vibration position database, it means that the product has moved to the vibration position, otherwise it means that the product is still in the process of moving to the vibration position.

[0153] Step S404: When the product is located at the vibration position, the product is dried by a product vibration dehydration method.

[0154] When the product moves to the vibration position, the device at the vibration position can dry the product by a product vibration dehydration method. The product vibration dehydration method will not be described here, but will be described in detail in subsequent embodiments.

[0155] Step S405: after a preset processing time, judging from a preset rotation position database whether the product has moved to the preset rotation position according to the transmission path image information.

[0156] Processing time refers to the time used for the product to be dried. After the processing time, the product will move to the next drying station for drying.

[0157] The rotation position database is a database obtained through training of a neural network model, which contains images of the product when it moves to the rotation position. It is a prior art and will not be described in detail here. By comparing the transmission path image information with the rotation position database, if the transmission path image matches the data in the rotation position database, it means that the product has moved to the rotation position, otherwise it means that the product is still in the process of moving to the rotation position.

[0158] Step S406: When the product is at the self-rotation position, the product is dried by a self-rotation dehydration method.

[0159] When the product moves to the self-rotation position, the device located at the self-rotation position can dry the product by using a product self-rotation dehydration method. The product self-rotation dehydration method will not be described here, but will be described in detail in subsequent embodiments.

[0160] Step S407: after a preset processing time, judging from a preset drying position database whether the product has moved to the preset drying position according to the transmission path image information.

[0161] The blow-drying position database is a database obtained through training of a neural network model, which contains images of the product when it moves to the blow-drying position. This is a prior art and will not be described in detail here. By comparing the transmission path image information with the blow-drying position database, if the transmission path image matches the data in the blow-drying position database, it means that the product has moved to the blow-drying position, otherwise it means that the product is still in the process of moving to the blow-drying position.

[0162] Step S408: When the product is located at the drying position, the air blowing device is controlled to blow air to dry the product.

[0163] When the product moves to the drying position, the device at the drying position can dry the product using a product drying method. The product drying method has been introduced in the previous steps 101 to 307 and will not be described in detail here.

[0164] Reference Figure 5 The product vibration dehydration method in step S404 includes the following steps:

[0165] In this embodiment, the drying box has an inlet and an outlet, and both the inlet and the outlet have air curtain doors, which can discharge air and adjust the discharge direction. The transmission track passes through the air curtain door, and the vibration position is located below the air curtain door, so that when the product passes through the air curtain door, the air curtain door can blow air to the product. In addition, a spring is provided on the hanger, and the product is suspended on the hanger through the spring. When the spring is extended and retracted, the product on the hanger can rise and fall vertically.

[0166] Step S500: When the product is located at the vibration position, the air outlet force of the air curtain door is determined according to the hanging weight information.

[0167] The air outlet force refers to the force with which the air curtain blows air to the product when the product is in the vibrating position. The air outlet force of the air curtain door is proportional to the hanging weight information of the product. The greater the hanging weight information of the product, the greater the air outlet force of the air curtain door needs to be. Therefore, the air outlet force of the air curtain door can be determined by the hanging weight information.

[0168] Step S501: Controlling the air curtain door to release air according to the air release force and the preset intermittent air release frequency to apply force to the product to vibrate and dry the product.

[0169] The intermittent air outlet frequency refers to the frequency at which the air curtain door blows air to the product. The air outlet force determines the amplitude of the product's vibration, and the intermittent air outlet frequency determines the frequency of the product's vibration. The air curtain door is controlled to exhaust air through the air outlet force and intermittent air outlet frequency so that the product can rise and fall vertically under the drive of the airflow, thereby shaking off the liquid on the surface.

[0170] Step S502: determining the following angular velocity of the air curtain door according to a preset product moving speed.

[0171] When the product is in the vibrating position, it will not stop but continue to move along the conveyor track at the preset product moving speed. Therefore, the wind blown out by the air curtain door needs to change with the direction of the product. The following angular velocity can be calculated by the moving speed of the product, which will not be described here.

[0172] Step S503: controlling the air curtain door to follow the direction of the product and continue to discharge air according to the following angular velocity.

[0173] After determining the following angular velocity, the air curtain door can rotate with the product at the following angular velocity, so that when the product is still in the vibrating position, the air curtain door can always blow air to the product.

[0174] Step S504: After a preset processing time, the air curtain door is controlled to exhaust air at a preset reference isolation strength to isolate the inside and outside of the drying box.

[0175] When the product is finished vibrating and drying, the air curtain door can be reset and the air can be discharged vertically at the reference isolation strength to isolate the drying box. The reference isolation strength is a value set by the technicians. When there is no product passing through, the air curtain door can isolate the inside and outside of the drying box by discharging air at the reference isolation strength.

[0176] In this embodiment, the drying box has a temperature adjustment function. When the product enters the drying box, the drying box can be heated to assist the product in drying. When the air curtain door blows air to the product to drive the product to vibrate and dry, the temperature inside the drying box decreases to prevent the temperature from leaking out of the air curtain door. When the air curtain door blows air vertically at the reference insulation force to isolate the drying box, the temperature inside the drying box increases.

[0177] In this embodiment, the transmission track at the vibration position can also be set to have a height difference. When the product moves to the vibration position, the product instantly falls from a high position to a low position, thereby generating a vibration effect.

[0178] Reference Figure 6 The product self-rotation dehydration method in step S406 includes the following steps:

[0179] Step S600: Acquire product image information at the rotation position.

[0180] The product image information here is an image of the product acquired by a camera when the product moves to the rotation position.

[0181] Step S601: retrieve the product model from a preset product database according to the product image information, and obtain the surface profile parameters according to the product model.

[0182] The process is the same as step S301 and will not be described in detail here.

[0183] Step S602: determining the blowing force point and the blocking force point farthest from the hanging axis of the product according to the surface profile parameters.

[0184] In this embodiment, the blowing device blows air to one side of the product, causing the product to rotate, thereby throwing out a portion of the liquid on the surface of the product and in the holes. After the product has completed the self-rotation drying, the blowing device blows air to the other side of the product, causing the product to be subjected to reverse force, thereby gradually stopping the rotation of the product.

[0185] The blowing force point is the blowing position point where the blowing device blows air to the product to cause the product to rotate, and the stopping force point is the blowing position point where the blowing device blows air to the product to stop the product from rotating. The blowing force point and the stopping force point are respectively located on both sides of the product.

[0186] When the surface profile parameters are determined, the point on the outermost contour surface of the product that is farthest from the suspension axis can also be determined. The farther the force point is from the suspension axis, the smaller the wind force required by the blowing device to drive the product to rotate or stop rotating. Therefore, the blowing force point and the stopping force point that are farthest from the suspension axis of the product can be determined based on the surface profile parameters.

[0187] Step S603: Control the preset blowing device to blow the blowing force point with the preset driving blowing force to drive the product to rotate.

[0188] The driving blowing force is a reference value set by the technicians. According to the setting of the blowing force point, the driving blowing force can drive the product to rotate, which will not be elaborated here.

[0189] Step S604: After the preset self-rotation and drying time, the blowing device is controlled to blow air to the blocking force point with a preset driving blowing force to drive the product to slowly stop rotating, and the driving blowing force is reduced at a preset force release speed until the product stops rotating.

[0190] The self-rotation and drying time is a reference value set by the technicians. During the self-rotation and drying time, the product is self-rotated and dried to spin out a portion of the liquid.

[0191] The force release speed is the speed at which the driving force of the blowing device decreases, which is a reference value set by the technicians. In order to adapt to the gradually decreasing rotation speed of the product, the driving force of the blowing device also needs to be slowly reduced to prevent the product from rotating in the opposite direction.

[0192] Reference Figure 7 , the mouthpiece replacement method includes the following steps:

[0193] In this embodiment, a plurality of guide plates are provided around the blowing nozzle. When the blowing device blows air to the guide plates, the guide plates can drive the blowing nozzle to rotate, thereby twisting the blowing nozzle.

[0194] Step S700: Control the blowing device to move to above the preset collection box, and obtain image status information of the blowing nozzle.

[0195] A collection box is provided in the drying box for placing the mouthpieces. When replacing the mouthpieces, the blowing device needs to be moved to the top of the collection box first, so that the replaced mouthpieces can fall directly into the collection box.

[0196] The image status information refers to an image of the mouthpiece moved over the collection box.

[0197] Step S701: determining the position information and posture information of the mouthpiece according to the image status information.

[0198] The position information of the mouthpiece refers to the specific position of the mouthpiece above the collection box. The posture information refers to the angle of the mouthpiece above the collection box. The position information and posture information of the mouthpiece can be directly obtained from the image state information through image analysis, and will not be described in detail here.

[0199] Step S702: Determine the setting angle of the guide plate according to the posture information.

[0200] Since the guide plate is arranged on the mouthpiece, when the posture of the mouthpiece is different, the setting angle of the guide plate is also different. After the posture information of the mouthpiece is determined, the setting angle of the guide plate can be determined through the posture information.

[0201] Step S703: controlling the direction angle of the preset auxiliary blowing device according to the setting angle.

[0202] The auxiliary air blowing device is used to assist in the replacement of the nozzle. If you want to unscrew or install the nozzle from the air blowing device, you need to use the air blowing device to blow air to the guide plate of the nozzle. The airflow of the air blowing device is perpendicular to the guide plate, and the force on the guide plate is the greatest at this time. Once the setting angle of the guide plate is determined, the direction angle of the auxiliary air blowing device can be determined by setting the angle.

[0203] Step S704: Control the auxiliary blowing device to blow air to the guide plate of the blowing nozzle to be replaced according to the orientation angle so as to unscrew the blowing nozzle from the blowing device and drop it into the collection box.

[0204] After the direction angle of the auxiliary air blowing device is adjusted, air is blown to the blowing nozzle to be replaced through the auxiliary air blowing device, and the blowing nozzle can be unscrewed from the air blowing device.

[0205] Step S705: Control the preset manipulator to move the new blowing nozzle to the position information to match with the thread of the blowing device, and control the auxiliary blowing device to blow air to the guide plate of the new blowing nozzle to tighten the blowing nozzle.

[0206] When replacing a new mouthpiece, a part of the new mouthpiece thread is installed by a manipulator according to the obtained mouthpiece position of the original mouthpiece, and then the guide plate is blown by a blowing device to tighten the mouthpiece.
