Description

Technical Field

[0001] The present invention relates to the field of cable processing, and in particular to a sheath base plastic method, system and terminal. Background Art

[0002] The sheath base molding machine is a kind of equipment used to produce cable sheaths. It is mainly used to heat and melt plastic particles, and then extrude the molten plastic through the screw of the extruder to form the shape of the cable sheath.

[0003] In the prior art, the cable is generally coated with a layer of talcum powder before passing through the sheath base molding machine. The talcum powder is used to increase the thermal deformation temperature of the external insulating plastic of the cable, improve the molding efficiency, and reduce the thermal fatigue of the insulating plastic during the processing. The cable is generally driven through a talcum powder pile by a conveyor device to coat the talcum powder.

[0004] When talcum powder is unevenly applied, it is easy to cause the molten sheath plastic raw material to come into contact with the external insulating plastic of the cable, causing the external insulating plastic of the cable to be damaged by heat, which in turn causes leakage of the cable when it is used. Summary of the invention

[0005] In order to improve the stability of cable processing and reduce the uneven coating of talcum powder, the present invention provides a sheath base plastic method, system and terminal.

[0006] In a first aspect, the present invention provides a sheath base molding method, which adopts the following technical solution: A sheath base molding method, comprising: Controlling a preset conveying device to pass the cable through a preset talcum powder pile, and obtaining a coating image of the cable after passing through the powder pile; Determining the coating thickness of the cable according to the coating image; When the coating thickness is lower than the preset heat insulation threshold, the powder shortage position is determined based on the coating image; Determine the spraying direction according to the powder shortage position; Control the preset spraying device to turn according to the spraying direction, and determine the coating distance according to the powder shortage position; Determine the spray quality based on coating thickness; Determine the spraying intensity based on the coating distance and spraying quality; According to the spraying intensity, the preset spraying device is controlled to spray talcum powder onto the cable according to the spraying quality.

[0007] By adopting the above technical solution, the coating condition of talcum powder can be judged by the appearance of the coated cable, so that talcum powder can be re-applied through a spraying device when there is uneven coating, thereby reducing the uneven coating of talcum powder and improving the stability of cable processing.

[0008] Optionally, the method further includes a cable inspection method, wherein the cable inspection method includes: When the coating thickness is lower than a preset thermal insulation threshold, an image of the cable before the cable passes through the powder pile is obtained; Determine the cable material based on the cable image; Determine powder adsorption parameters according to cable material; Determine the speed correction parameter according to the powder adsorption parameter; The preset transmission speed of the transmission device is corrected according to the speed correction parameter.

[0009] By adopting the above technical solution, the material of the insulating plastic on the outside of the cable can be judged by the appearance of the cable, thereby determining the adsorption of talcum powder by the insulating plastic, and then adjusting the speed at which the conveying device transmits the cable so that cables of different materials can fully absorb the talcum powder, thereby reducing the uneven coating of talcum powder.

[0010] Optionally, the cable inspection method further includes: When the coating thickness is lower than the preset thermal insulation threshold, it is determined whether there are foreign objects on the cable based on the cable image; When there is foreign matter on the cable, the location and type of the foreign matter are determined based on the cable image; Determine the cleaning intensity according to the type of foreign matter; Determine the cleaning direction according to the location of the foreign matter; According to the cleaning direction, the preset cleaning device is controlled to spray the cleaning liquid onto the cable according to the cleaning intensity.

[0011] By adopting the above technical solution, when the insulating plastic on the outside of the cable is contaminated with foreign matter, the adsorption of talcum powder by the insulating plastic is easily reduced. Whether the insulating plastic is contaminated with foreign matter can be judged by the appearance of the cable, and the cable can be cleaned by a cleaning device when it is contaminated with foreign matter, thereby reducing the uneven coating of talcum powder.

[0012] Optionally, the cable inspection method further includes: When there is a foreign object on the cable, determine the area of ​​the foreign object based on its location; When the area of ​​the foreign matter is larger than the preset cleaning threshold, the removal position is determined based on the cable image; Determine the removal schedule based on the removal location; The preset removing device is controlled according to the removing stroke to remove the foreign matter from the cable.

[0013] By adopting the above technical solution, when the area of ​​foreign matter contaminated on the cable is large, it is not easy to remove the foreign matter through the cleaning device. At this time, the foreign matter is removed by the removal device, and then the remaining foreign matter is removed by the cleaning device, thereby reducing the situation of residual foreign matter on the cable.

[0014] Optionally, a talcum powder inspection method is also included, and the talcum powder inspection method includes: When the coating thickness is lower than a preset heat insulation threshold, acquiring a powder pile image of the talcum powder pile; Judging whether there is talcum powder agglomeration based on the powder pile image; When talc agglomeration is present, obtain the ambient humidity; When the ambient humidity exceeds a preset agglomeration threshold, the heating temperature is determined according to the ambient humidity; Controlling a preset heating device to heat a preset talcum powder pile according to a heating temperature; When the ambient humidity does not exceed the preset agglomeration threshold, the agglomeration degree is determined based on the powder pile image; Determine the heating temperature and heating time according to the degree of agglomeration; The preset heating device is controlled according to the heating time to heat the preset talcum powder pile according to the heating temperature.

[0015] By adopting the above technical scheme, when talcum powder clumps due to excessive humidity, the adhesion of talcum powder is easily reduced. By detecting the external humidity, the talcum powder is continuously heated by a heating device when the external humidity is too high. When the external humidity is low, the talcum powder is heated regularly by a heating device according to the agglomeration of the talcum powder, thereby reducing the agglomeration of the talcum powder.

[0017] By adopting the above technical solution, while the powder pile is heated by the heating device, the decomposition speed of the agglomerated talcum powder is accelerated by the vibration device, thereby reducing the agglomeration of the talcum powder and improving the adhesion of the talcum powder.

[0018] Optionally, the talcum powder inspection method further comprises: When the coating thickness is lower than the preset heat insulation threshold, it is determined whether there is foreign matter in the powder pile based on the powder pile image; When there are foreign objects in the powder pile, the removal position is determined based on the powder pile image; Determine the shoveling stroke according to the shoveling position; Control the preset scraping device to scrape away foreign matter according to the scraping stroke; Based on the absence of foreign matter in the powder pile, the purity of the powder pile is determined based on the powder pile image; Determine the powder pile coating parameters according to the powder pile purity; The preset conveying speed of the conveyor device is modified according to the powder pile coating parameters.

[0019] By adopting the above technical solution, when talcum powder is left for a long time or is mixed with foreign matter, the purity of the talcum powder pile is likely to decrease, thereby reducing the adhesion of the talcum powder. The purity of the talcum powder can be judged based on its appearance, and the transmission speed of the transmission device can be controlled based on the purity, thereby allowing the external insulating plastic of the cable to be fully coated with talcum powder.

[0023] By adopting the above technical solution, the coating condition of talcum powder can be judged by the appearance of the coated cable, so that talcum powder can be re-applied through a spraying device when there is uneven coating, thereby reducing the uneven coating of talcum powder and improving the stability of cable processing.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: The coating condition of talcum powder is judged by the appearance of the coated cable, so that talcum powder can be re-applied through the spraying device when there is uneven coating, thereby reducing the uneven coating of talcum powder and improving the stability of cable processing; The material of the insulating plastic on the outside of the cable is judged by the appearance of the cable, so as to determine the adsorption of the insulating plastic to talcum powder, and then adjust the speed of the transmission device to transport the cable so that cables of different materials can fully absorb talcum powder, reducing the uneven coating of talcum powder; When the insulating plastic on the outside of the cable is contaminated with foreign matter, it is easy to reduce the adsorption of talcum powder by the insulating plastic.

[0039] Step 105: Determine the spraying quality according to the coating thickness.

[0040] The spraying quality refers to the weight of talcum powder sprayed by the spraying device per unit time. The spraying quality is adjusted according to the coating thickness so that the cable can be fully coated with talcum powder. The spraying quality can be obtained through the spraying quality matching model. The spraying quality matching model refers to a neural network model obtained in advance through sample training.

[0049] Step 202: Determine powder adsorption parameters according to the cable material.

[0050] The powder adsorption parameters refer to the parameters corresponding to the cable material used to reflect the adsorption performance of the cable to talcum powder. The powder adsorption parameters can be obtained by querying the powder adsorption database.

[0053] Step 204: Correct the preset transmission speed of the transmission device according to the speed correction parameter.

[0054] The transmission speed of the transmission device is adjusted according to the material of the cable, thereby speeding up the transmission speed of the cable with better adsorption performance and slowing down the transmission speed of the cable with poor adsorption performance, so that cables of different materials can be fully coated with talcum powder when passing through the talcum powder pile, reducing the uneven coating of talcum powder.

The cleaning liquid refers to the liquid stored in the cleaning device and sprayed out through the cleaning device. The cleaning device and cleaning liquid are selected by the staff according to actual conditions and will not be elaborated here.

[0062] Cleaning force refers to the water pressure of the cleaning liquid sprayed out by the cleaning device. The cleaning force is adjusted according to the type of foreign matter, so that difficult-to-remove foreign matter such as stains can be removed by greater water pressure, and easy-to-remove foreign matter such as paper can be removed by lower water pressure. The cleaning force can be obtained through a cleaning force matching model. The cleaning force matching model refers to a neural network model obtained in advance through sample training.

[0063] Step 208: Determine the cleaning direction according to the location of the foreign matter.

[0064] The cleaning direction refers to the angle when the cleaning device is facing the position of the foreign body. The cleaning direction can be obtained based on the relative relationship between the position of the cleaning device and the position of the foreign body. The calculation method of the cleaning direction is selected by the staff based on actual conditions and will not be elaborated here.

[0065] Step 209: According to the cleaning direction, a preset cleaning device is controlled to spray cleaning liquid onto the cable according to the cleaning force.

[0066] When there are foreign objects on the cable, it is easy to cause the cable's adsorption performance of talcum powder to decrease. The foreign objects on the cable can be removed by a cleaning device, thereby reducing the uneven coating of talcum powder.

[0067] Reference Figure 4 , the cable inspection method also includes: Step 210: When there is a foreign object on the cable, determine the area of ​​the foreign object according to the position of the foreign object.

[0068] The foreign body area refers to the area of ​​the foreign body on the cable image. The foreign body area can be obtained through a foreign body area recognition model. The foreign body area recognition model refers to a neural network model obtained in advance through sample training.

[0071] The removal position refers to the position of the point of action of the removal device on the foreign body when removing the foreign body. The removal position first identifies the area on the foreign body that is easily acted upon by the removal device, and then selects a point closest to the center of gravity of the foreign body from the area as the removal position. The removal position can be obtained through a removal position recognition model.

[0072] Step 212: Determine the removal stroke according to the removal position.

[0073] The removal stroke refers to the path taken by the removal device to remove foreign matter from the cable. The removal stroke can be obtained through a removal stroke matching model. The removal stroke matching model refers to a neural network model obtained in advance through sample training.

[0074] Step 213: Control a preset removal device according to the removal stroke to remove the foreign matter from the cable.

[0075] When the foreign matter is a solid object such as plastic or paper, the size of the foreign matter is determined from the cable image. If the foreign matter is too large, a removal device is used to remove the large foreign matter, and a cleaning device is used to clean the small foreign matter, thereby reducing the presence of foreign matter on the cable.

[0076] Reference Figure 5 , talcum powder inspection methods include: Step 300: When the coating thickness is lower than a preset heat insulation threshold, a powder pile image of the talcum powder pile is obtained.

[0077] The powder pile image refers to a picture of a talcum powder pile. The powder pile image can be obtained through a camera. The method for obtaining the powder pile image is selected by the staff according to actual conditions and will not be elaborated here.

[0078] Step 301: judging whether talcum powder agglomerates according to the powder pile image.

[0079] The agglomeration recognition model can be used to determine whether talcum powder agglomerates. The agglomeration recognition model refers to a neural network model obtained through sample training in advance.

[0080] Step 302: When talcum powder agglomerates, obtain the ambient humidity.

[0081] The presence of talcum powder agglomerates means that the humidity of the talcum powder is too high. The ambient humidity refers to the air humidity value in the space where the talcum powder pile is located. The ambient humidity can be obtained through a humidity sensor. The method for obtaining the ambient humidity is selected by the staff according to the actual situation and will not be elaborated here.

[0082] Step 303: When the ambient humidity exceeds a preset agglomeration threshold, a heating temperature is determined according to the ambient humidity.

[0083] The agglomeration threshold refers to the lowest humidity value at which talcum powder is prone to agglomeration. The agglomeration threshold is selected by the staff according to the actual situation and will not be described in detail here.

[0084] The heating device refers to a device that is preset at the bottom of the talc powder pile and is used to heat the talc powder pile. The heating device is selected by the staff according to the actual situation and will not be described in detail here. The heating temperature refers to the temperature value of the talc powder heated by the heating device to reduce the agglomeration of the talc powder. The heating temperature can be obtained from the heating temperature database. The heating temperature database refers to a database that records the environmental humidity obtained in advance and its corresponding heating temperature data.

[0085] Step 304: controlling a preset heating device to heat a preset talcum powder pile according to a heating temperature.

[0086] When the base molding machine is started, the talcum powder pile is continuously heated according to the heating temperature by the heating device, and the heating device is turned off when the base molding machine is turned off, so that the talcum powder pile is always kept dry during the operation of the base molding machine, reducing the agglomeration of talcum powder.

[0087] Step 305: When the ambient humidity does not exceed the preset agglomeration threshold, the agglomeration degree is determined according to the powder pile image.

[0088] The fact that the environmental humidity does not exceed the agglomeration threshold value indicates that the humidity of the environment is low at this time. The agglomeration of talcum powder is caused by previous moisture. The degree of agglomeration refers to a pre-set value used to show the agglomeration condition of talcum powder. The greater the mass of talcum powder agglomerates, the higher the value of the degree of agglomeration. The degree of agglomeration can be obtained through an agglomeration degree matching model. The agglomeration degree matching model refers to a neural network model obtained through sample training in advance.

[0089] Step 306: Determine the heating temperature and heating time according to the degree of agglomeration.

[0091] Step 307: controlling a preset heating device to heat the preset talcum powder pile at a heating temperature according to the heating time.

[0092] When the humidity of the environment is high, the heating device is used to continuously heat the talc to reduce the agglomeration of the talc due to the influence of the environment. When the humidity of the environment is low, the agglomerated talc is heated and decomposed by the heating device, thereby reducing the overheating of the talc caused by continuous heating of the talc.

[0093] Reference Figure 6 , talcum powder inspection methods also include: Step 308: When talcum powder agglomerates, determine the center position of the agglomeration according to the powder pile image.

[0094] The center position of the agglomerate refers to the coordinates of the center point of the area where the agglomerates exist in the powder pile image. The center position of the agglomerate can be obtained through a center position matching model. The center position matching model refers to a neural network model obtained in advance through sample training.

[0095] Step 309: Determine the vibration stroke according to the center position of the agglomerate.

[0096] The vibration device refers to a device that breaks up agglomerated talcum powder through vibration. The vibration device generally uses a vibration rod. The vibration device is selected by the staff according to actual conditions and will not be described in detail here.

[0097] The vibration stroke refers to the path of the vibration device vertically inserted into the talcum powder pile from the center of the agglomerate. The vibration stroke can be obtained through a vibration stroke matching model. The vibration stroke matching model refers to a neural network model obtained in advance through sample training.

[0098] Step 310: Determine the vibration frequency according to the degree of agglomeration.

[0099] The vibration frequency refers to the frequency of vibration generated by the vibration device. The higher the vibration frequency, the better the effect of the vibration device in breaking up the agglomerated talcum powder. The vibration frequency can be obtained by querying the vibration frequency database. The vibration frequency database refers to a database that records the agglomeration degree and its corresponding vibration frequency obtained in advance through experiments.

[0100] Step 311: Control a preset vibration device to insert into the powder pile according to the vibration stroke, and control the preset vibration device to vibrate according to the vibration frequency.

[0101] When the talc powder is heated by the heating device, the talc powder is vibrated by the vibration device, thereby accelerating the decomposition speed of the agglomerated talc powder and reducing the agglomeration of the talc powder.

[0102] Reference Figure 7 , talcum powder inspection methods also include: Step 312: When the coating thickness is lower than a preset heat insulation threshold, determine whether there is foreign matter in the powder pile based on the powder pile image.

The scraping stroke can be obtained through the scraping stroke matching model. The scraping stroke matching model refers to a neural network model obtained in advance through sample training.

[0108] Step 315: Control the preset scraping device to remove the foreign matter according to the scraping stroke.

[0109] The foreign matter in the talcum powder pile is shoveled out by the shoveling device and taken away from the talcum powder pile.

[0110] Step 316: Based on the fact that there is no foreign matter in the powder pile, the purity of the powder pile is determined according to the powder pile image.

[0111] Powder pile purity refers to the purity value of talc powder used in talc powder pile. When talc powder is left for a long time, it is easily affected by temperature and becomes aged and yellowed, resulting in a decrease in the purity value of talc powder.
