[0068] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0069] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0070] See also Figure 1 , Figure 2 and Figure 3, this embodiment provides a hydraulic hose production line, which can be used for the production of hydraulic hoses.

[0071] The hydraulic hose production line provided in this embodiment includes a feeding device 100, a cutting device 200, a dust cleaning device 300, a degumming device 400, a sponge shooting device 500, a transfer device 600, a fitting assembly device 700, an inner cavity cleaning device 900, and a discharging device.

[0072] In this embodiment, the hydraulic hose production line is arranged in an overall "冂" shape, so as to reasonably utilize the space in the width direction and make the structural layout more compact.

[0073] Among them, the feeding device 100 includes a feeding turntable 110, and the feeding turntable 110 can place rubber hoses. Specifically, first, the whole roll of rubber hoses (hereinafter collectively referred to as rubber hoses) are manually carried onto the feeding turntable 110, the rubber hoses are untied, and then connected to the traction device of the cutting device 200 for feeding and conveying.

[0074] The cutting device 200 is arranged downstream of the feeding device 100 and is used for cutting the rubber hoses to a fixed length. The cutting device 200 traction the rubber hoses on the feeding turntable 110 to the cutting device 200 for conveying, and the cutting device 200 also conveys the rubber hoses to the next process through the first conveying device. Optionally, the first conveying device can be selected from belt conveying, roller conveying or manipulator clamping conveying.

[0075] The dust cleaning device 300 is arranged on the discharge side of the first conveying device and is used for cleaning the residual powder on the cut rubber hoses. The dust cleaning process is an important process for cleaning the rubber hoses. The dust cleaning device 300 in this process is equipped with two test tube brushes, two end face brushes and an air gun. The two test tube brushes and the two end face brushes can simultaneously clean the inner cavities and outer end faces of both ends of the rubber hoses for the powder generated by cutting. After the powder cleaning is completed, the equipped air gun automatically blows air on the surface and inner cavity of the rubber hoses to remove the residual powder.

[0076] The degumming device 400 is connected to the dust cleaning device 300 through the second conveying device and is used for end degumming treatment of the rubber hoses that need degumming treatment. The rubber hoses that do not need degumming are directly conveyed to the next process.

[0077] In this embodiment, the degumming device 400 in the degumming process is equipped with a double-head degumming head, which can simultaneously strip the outer rubber or inner and outer rubber at both ends of the rubber hose. Among them, the degumming method can be realized by blade cutting or grinding. The second conveying device can be selected from belt conveying, roller conveying or manipulator clamping conveying.

[0078] The sponge shooting device 500 includes a sponge shooting gun and a recovery device 510. The sponge shooting gun is used to shoot sponge projectiles at one end of the rubber hose, and the recovery device 510 is arranged at the other end of the rubber hose and is used to recover the shot sponge projectiles.

[0079] Furthermore, the sponge ejection device 500 also includes an infrared detection device, which is arranged at the other end of the hose, that is, the end opposite to the sponge ejection gun. It can be understood that the sponge ejection gun fires sponge projectiles of corresponding specifications to clean the inner cavity of the hose. The infrared detection device detects whether the sponge projectile is ejected from the inner cavity of the hose. If it is detected that it is not ejected, an alarm prompts (prompting the operator to intervene to ensure the normal operation of subsequent processes) to prevent the sponge projectile from being retained in the inner cavity of the hose. The ejected sponge projectile can be recovered by the recovery device 510 as the cleaned sponge projectile.

[0080] The transfer device 600 is used to transfer the rubber hose that has been cleaned by the sponge projectile to the next process. The transfer device 600 can be a manipulator, and two clamps are arranged at the end of the manipulator to clamp the two ends of the rubber hose and constrain the rubber hose to be U-shaped.

[0081] The accessory assembly device 700 is used to sequentially install a sleeve and a rod core on a hose to obtain a hose assembly, and is used to transfer the hose assembly to the next process.

[0082] The inner cavity cleaning device 900 is used to blow clean the inner cavity of the hose assembly and install a dust cover.

[0083] The unloading equipment is used to clamp the hose assembly (ie, hydraulic hose) and unload the product. In some embodiments, the unloading equipment can be used to transfer materials between the accessory assembly equipment 700 and the inner cavity cleaning equipment 900, thereby saving the handling device for the inner cavity cleaning equipment 900 and saving costs.

[0084] Furthermore, the cutting device 200 further includes an exhaust device connected to the closed cutting chamber, and the exhaust device is used to extract powder generated by cutting to ensure the cleanliness of the production environment.

[0085] The above-mentioned accessory assembly equipment 700 includes a crimping machine, which includes a crimping mold and a monitoring module. The crimping mold is used to crimp the sleeve and core rod on the hose, and the monitoring module determines whether the crimping is qualified by monitoring the displacement and pressure value.

[0086] See also Figure 1 , Figure 2 and Figure 3 This embodiment also provides a method for assembling a hydraulic hose. The assembly method is applied to the hydraulic hose production line provided above. The assembly method of the hydraulic hose includes the following steps:

[0087] S100: The rubber hose is delivered to the cutting device 200 through the feeding device 100 .

[0088] Specifically, the hoses are first moved to the loading turntable 110 manually, and the hoses are unbundled and then loaded into the traction structure for loading.

[0089] S200: Cutting the hose to a fixed length by using the cutting device 200.

[0090] S300: Remove the powder remaining on the surface, end face and inner cavity of the hose after cutting.

[0091] Specifically, the two test tube brushes, two end face brushes and an air gun provided with the dust cleaning device 300 are mainly used to clean the inner cavity and the outer end face of the two ends of the hose.

[0092] S400 uses a sponge shotgun to clean the inner cavity of the hose.

[0093] S500: Assemble sleeves at both ends of the cleaned hose, then assemble the core rod in the hose, and finally buckle the sleeve to buckle the sleeve into the buckle groove of the core rod to assemble the hose assembly.

[0094] S600: Blow air to clean the inner cavity of the hose assembly and install dust covers on both ends of the cleaned hose assembly.

[0095] S700: Assembly completed, product rolls off the production line.

[0096] Among them, a stripping step is also provided between step S400 and step S500. In the stripping step, a double stripping head is configured in the stripping equipment 400 to simultaneously strip the outer rubber or the inner and outer rubber at both ends of the hose. The hose that has been stripped is then transferred to the next process to execute step S500. The hose that does not need stripping can be directly transferred to the next process to execute step S500.

[0097] The above step S200 also includes:

[0098] S210: During the cutting process, an exhaust device is used to extract the powder generated by cutting.

[0099] Specifically, the hose enters the closed cutting chamber of the cutting device 200 for cutting, and the extraction device is activated during cutting to extract the powder generated by cutting in time. The extraction device cannot ensure that all the powder can be extracted, and powder may remain on the surface, end face and inner cavity of the hose. Therefore, the hose needs to be transported to the dust cleaning process by the first conveying device to perform step S300.

[0100] S220: After the cutting is completed, a marking pen is used to mark the end of the cut hose, and the installation position of the sleeve is determined by the marking. The marking distance is retrieved by the equipment from the basic parameter library. The purpose of marking is to facilitate the subsequent inspection of the assembly to determine whether the sleeve is in place.

[0101] The above step S300 includes:

[0102] S310: two test tube brushes are arranged in the dust cleaning device 300 and extended into the inner cavity from both ends of the rubber hose respectively;

[0103] S320: two end face brushes are arranged in the dust cleaning device 300 to clean both ends of the hose;

[0104] S330: The residual powder is removed by blowing air on the surface, end face and inner cavity of the hose through an air gun arranged in the dust removal device 300.

[0105] It should be noted that there is no order distinction between the above step S310 and step S320, and they can be performed simultaneously or step by step.

[0106] The above step S400 includes:

[0107] S410: Align one end of the rubber hose with the sponge projectile gun, and arrange a recovery device 510 at the other end to recover the sponge projectile;

[0108] S420: Control the sponge projectile gun to fire sponge projectiles of corresponding specifications to clean the inner cavity of the hose;

[0109] S430: Using an infrared detection device to detect the inner cavity of the hose to determine whether the sponge projectile is ejected from the inner cavity of the hose;

[0110] S440: If the sponge projectile is ejected, the hose is transferred to the next process to execute step S500. Otherwise, an alarm is issued to prompt the operator to intervene to ensure the normal operation of the subsequent process.

[0111] In this embodiment, the accessory assembly equipment 700 includes a sleeve assembly device 710 , a core rod assembly device 720 and a joint pressing device 730 .

[0112] Specifically, in the above step S500, in the sleeve assembly process, the sleeve assembly device 710 includes a sleeve vibration plate 711 and a sleeve assembly manipulator. The clamping and moving mechanism clamps the hose, and after the transfer device 600 releases the hose, the clamping and moving mechanism clamps the two ends of the hose, so that the two ends of the hose are clamped upward in a U shape. The sleeve vibration plate 711 arranges the sleeves in a regular order, and the sleeve assembly manipulator clamps the sleeves and transfers them to the two ends of the hose respectively. The clamping claws of the sleeve assembly manipulator perform a 180° back and forth rotation (i.e., rotate 180° clockwise and then 180° counterclockwise, and repeat this) to solve the problem of difficulty in assembly caused by the irregular end face of the hose. After the assembly is completed, it is clamped and transferred to the core rod installation process through the clamping and transfer mechanism. Among them, the sleeve is loaded into the sleeve vibration plate 711 by manual loading.

[0113] In the above step S500, in the core rod assembly process, the core rod assembly device 720 includes a core rod vibration disk 721, a core rod assembly robot and a pressing device. The core rod vibration disk 721 arranges the core rods in a regular order, and the core rod assembly robot clamps the core rods and transfers them to the inner cavities at both ends of the hose. After the assembly is completed, the pressing device presses down the core rod so that the core rod is assembled in place. After the processing is completed, the hose is transferred by the clamping transfer mechanism. The core rod in the above-mentioned core rod vibration disk 721 is manually loaded. The pressing device can be driven by an electric cylinder or an oil cylinder.

[0114] Furthermore, in the above step S500, assembling the core rod in the hose includes:

[0115] S510: Prepare a high frequency heating rod at 80±5°C.

[0116] S520: Insert high-frequency heating rods into the inner cavity from both ends of the hose for heating.

[0117] S530: After the preset time, pull out the high-frequency heating rod and then insert the core rod.

[0118] S540: After the core rod is assembled in place, the hose is transferred to the next process to execute step S600.

[0119] It can be understood that the use of a high-frequency heating rod at 80±5°C to heat the inner cavity of the hose can, on the one hand, expand the port of the hose and, on the other hand, cause the inner cavity of the hose to expand by heat, thereby facilitating the insertion of the core rod.

[0120] The insertion depth of the high-frequency heating rod should be greater than or equal to the length of the core rod to ensure that the core rod can be inserted into place.

[0121] In this embodiment, the preset time length for the high-frequency heating rod to heat the inner cavity of the hose is 3±1 seconds.

[0122] In some embodiments, in order to ensure that the sleeve and the core rod are assembled in place, a positioning detection process is set after the core rod assembly process. In the positioning detection process, the accessory assembly equipment 700 also includes a positioning detection device to detect whether the sleeve and the core rod are assembled in place through positioning detection, and an alarm is given if they are not in place. After the detection is completed, the clamping transfer mechanism transfers the hose to the next process for buckling.

[0123] In the above-mentioned joint crimping process, the joint crimping device 730 includes a feeding mechanism, a crimping machine, a positioning mechanism, and a monitoring module is provided in the crimping machine. The feeding mechanism turns the U-shaped hose by 90° and pushes it horizontally into the crimping machine mold of the crimping machine. The positioning mechanism positions the core rod and sleeve to ensure that the core rod, sleeve and hose are sent to the designated position, and the crimping machine crimps.

[0124] The monitoring module is selected as ICC4 module, and the crimping process is monitored by ICC4 module (specifically, displacement and pressure value are monitored to determine whether the crimping is qualified). After the crimping is completed, the crimping machine mold opens, and the delivery mechanism removes the hose from the crimping machine mold, and the process ends. The mobile clamping mechanism is reset, and the processed hose assembly is sent to the next process.

[0125] Furthermore, after the crimping is completed, a crimping detection process is configured to detect the conformity of the outer diameter of the sleeve after crimping and whether the sleeve is crimped into the core rod groove. The crimping detection process is equipped with contour detection and crimping groove detection devices. The contour detection device checks the conformity of the outer diameter of the sleeve after crimping, and the crimping groove device detects whether the sleeve is crimped into the core rod groove. After the detection is completed, the mobile clamping mechanism transfers the hose to the next process.

[0126] In this embodiment, in the inner cavity cleaning process, the inner cavity cleaning device 900 includes a dust cover removal device, a blowing device, and a dust cover recovery box. The dust cover removal device removes the plugging cover of the core rod and puts it into the plugging cover recovery box, and the blowing device blows air into the inner cavity of the hose assembly to clean the inner cavity of the hose assembly. After the processing is completed, the triple robot transfers the hose assembly to the next process.

[0127] Thus, the above step S600 includes:

[0128] S610: First remove the original plugging caps at both ends of the core rod;

[0129] S620: Use the air blowing device to blow and clean the inner cavity of the hose assembly;

[0130] S630: Install dust covers on both ends of the core rod using the dust cover assembly robot.

[0131] The blowing device uses filtered compressed air to blow and clean the inner cavity of the hose assembly. The automatic loading of the dust cover is performed by manually loading a sufficient number of dust covers into the dust cover vibration plate 910.

[0132] The above-mentioned unloading equipment adopts a triple robot, which is used to transfer the cleaned hose assembly to the finished product area, and the product is unloaded and the assembly processing is completed.

[0133] Among them, the triple robot is equipped with two clamping heads, and both ends of the hose assembly are clamped in a U shape for transfer.

[0134] In some embodiments, the triple robot can also work between the inner cavity cleaning device 900 and the accessory assembly device 700, and is used to clamp and transfer the hose assembly transmitted from the mobile clamping mechanism in the accessory assembly device 700 to the inner cavity cleaning device 900 for air blowing cleaning, and then perform unloading operations together after the dust cover of the hose assembly is installed.

[0135] In some embodiments, a label pasting device 800 may be provided between the accessory assembly device 700 and the inner cavity cleaning device. Specifically, the hose assembly is transferred to the label pasting process by a mobile clamping mechanism, and the label pasting device 800 prints the label in real time, and automatically folds it in half and pastes it on the hose. Then, the triple robot transfers the hose assembly pasted with the label to the inner cavity cleaning process.

[0136] Compared with the prior art, the hydraulic hose production line provided in this embodiment realizes automated assembly line, reduces manual handling between adjacent processes, has good processing continuity, high automation, and greatly improves production efficiency. At the same time, it reduces the input of manpower and material resources and reduces the labor intensity.

[0137] Furthermore, the combined process of the dust cleaning operation (dust brushing + air blowing) of the dust cleaning device 300 + the sponge ejection cleaning of the sponge ejection device 500 + the air blowing of the hose assembly by the inner cavity cleaning device 900 can ensure the high cleanliness of the hose assembly in batches. NAS8 can be achieved in actual production.

[0138] Furthermore, automatic assembly and crimping methods replace traditional manual work, the process quality is controlled, and the production quality is guaranteed.
