[0033] The following describes in detail the specific implementation methods according to the present disclosure in conjunction with the accompanying drawings.

[0034] like Figures 1-8As shown, a hose feeding mechanism comprises a straightening device 1, a first feeding device 2 and a second feeding device 3 which are matched with each other; the first feeding device 2 and the second feeding device 3 are arranged in front of and behind each other and staggered, specifically, the rear end of the first feeding device 2 is aligned with the front end of the second feeding device 3, and the straightening device 1 is arranged between the first feeding device 2 and the second feeding device 3, more specifically, the straightening device 1 is arranged above the first feeding device 2 and the second feeding device 3; the first feeding device 2 comprises at least two groups of front and rear distributed fixed clamping hands 4 and moving clamping hands 6 which are matched with each other, specifically, the fixed clamping hands 4 are located outside the moving clamping hands 6; the second feeding device 3 comprises at least two groups of front and rear distributed fixed clamping hands 4 and at least one group of moving clamping hands 6 which are matched with each other, specifically, the fixed clamping hands 4 are also located outside the moving clamping hands 6; the fixed clamping hands 4 in the same feeding device are driven by corresponding fixed up-down driving devices 5 to be movable up and down; the moving clamping hands 6 in the same feeding device are respectively driven by corresponding moving up-down driving devices 7 and moving front-rear driving devices 8 to be movable up and down and front and rear; the straightening device 1 comprises a straightening clamping hand 9, and the straightening clamping hand 9 is respectively driven by corresponding straightening up-down driving devices 10 and straightening left-right driving devices 11 to be movable up and down and left and right, specifically, the straightening clamping hand 9 is arranged in one group. Through the above arrangement, the hose 21 can be clamped at the first end, straightened and clamped at the second end during the feeding process, so that other mechanisms can process the two ends of the hose.

[0035] In this embodiment, for the number setting of the fixed clamping hands 4 and the moving clamping hands 6 in the first feeding device 2, the fixed clamping hands 4 and the moving clamping hands 6 are respectively arranged in five groups.

[0036] In this embodiment, for the number setting of the fixed clamping hands 4 and the moving clamping hands 6 in the second feeding device 3, the fixed clamping hands 4 are arranged in four groups, and the moving clamping hands 6 are arranged in three groups. Since the moving clamping hands 6 are one group less than the fixed clamping hands 4, after the last group of fixed clamping hands 4 clamps the hose 21, other mechanical hands are needed to take away the processed hose 21. When the number of the fixed clamping hands 4 and the moving clamping hands 6 is the same, the last group of moving clamping hands 6 can directly take away the processed hose 21 in the last group of fixed clamping hands 4, and the hose 21 can be unloaded by using the gravity of the hose 21 when the moving clamping hands 6 are released, thereby eliminating the setting of the mechanical hands.

[0037] As shown in the figure, Figures 2-7As shown, the fixed gripper 4, the movable gripper 6, and the straightening gripper 9 each include a gripper body and a pneumatic finger 14 for driving the gripper body to open and close. Specifically, the gripper body includes a first gripper 12 and a second gripper 13 that cooperate with each other. By arranging the first gripper 12 and the second gripper 13 on the pneumatic finger 14, the pneumatic finger 14 can be used to conveniently and quickly grasp objects.

[0038] Preferably, Figures 2-7 As shown, in order to improve the processing efficiency, the fixed gripper 4, the movable gripper 6 and the straightening gripper 9 all include more than two groups of gripper bodies and a pneumatic finger 14, and the pneumatic finger 14 can be used to simultaneously drive the corresponding more than two groups of gripper bodies to open and close; specifically, the two jaws of the pneumatic finger 14 are respectively connected with a first clamping plate 15 and a second clamping plate 16 that cooperate with each other, the first clamping plate 15 and the second clamping plate 16 are arranged adjacent to each other, and the first gripper 12 and the second gripper 13 of the corresponding gripper body are respectively connected to the first clamping plate 15 and the second clamping plate 16, so that when the two jaws are opened and closed, they can drive the first clamping plate 15 and the second clamping plate 16 to move, and synchronously drive the corresponding first gripper 12 and the second gripper 13 to move. By respectively providing two or more groups of gripper bodies on the fixed gripper 4, the movable gripper 6 and the straightening gripper 9, the processing efficiency can be improved, so that more than two hoses 21 can be clamped and processed at one time. At the same time, since each pneumatic finger 14 can be used to drive the corresponding two or more groups of gripper bodies, the structure can be simplified and the synchronization rate of the action can be guaranteed while improving the processing efficiency. Only a single pneumatic finger 14 is needed to drive more than two groups of gripper bodies, thereby saving tool costs to a certain extent. Of course, those skilled in the art should know that, if necessary, each group of gripper bodies can be connected to a corresponding pneumatic finger 14 for use. As a specific embodiment, the fixed gripper 4, the movable gripper 6 and the straightening gripper 9 each include six groups of gripper bodies and one pneumatic finger 14, so that six hoses 21 can be processed at one time.

[0039] Preferably, as shown in Figure 6, a clamping hole 17 for inserting the hose 21 is provided between the first clamping hand 12 and the second clamping hand 13 of the fixed clamping hand 4, so that the fixed clamping hand 4 can be more stable when clamping the hose 21, and the hose 21 is not easy to swing, so that subsequent processing steps can be better handled.

[0040] Preferably, Figure 2 and Figure 7As shown, in order to improve stability and accuracy, the first clamping hand 12 and the second clamping hand 13 are respectively provided with a clamping groove 18 and a clamping block 19 which can be clamped with each other on the side opposite to each other, so that the first clamping hand 12 and the second clamping hand 13 can be clamped to the hose 21 at the same time, and the clamping block 19 is clamped into the clamping groove 18, so that the first clamping hand 12 and the second clamping hand 13 can be stably and accurately folded, and the first clamping hand 12 and the second clamping hand 13 are not easy to be dislocated, so that the hose 21 can be clamped more stably. Specifically, the clamping groove 18 is arranged on the first clamping hand 12, and the clamping block 19 is arranged on the second clamping hand 13. Of course, the clamping groove 18 can also be arranged on the second clamping hand 13, and the clamping block 19 is arranged on the first clamping hand 12. Moreover, the clamping groove and the clamping block can also be arranged on the first clamping hand 12 respectively, and the clamping block and the clamping groove which can be clamped with each other can also be arranged on the second clamping hand 13. At the same time, the clamping groove 18 and the clamping block 19 can be arranged only on the fixed clamping hand 4 and the straightening clamping hand 9, that is, the clamping groove 18 and the clamping block 19 are not arranged on the moving clamping hand 6, so as to avoid affecting the moving clamping hand 6 to realize material taking due to the arrangement of the clamping groove 18 and the clamping block 19.

[0041] Similarly, as shown in Figure 6 , the clamping hole 17 for penetrating the hose 21 can also be arranged between the first clamping hand 12 and the second clamping hand 13 of the straightening clamping hand 9, so that the straightening clamping hand 9 can limit the hose 21 during clamping and straightening, and the hose 21 is not easy to deviate from the preset route. Of course, if necessary, the clamping hole 17 can also be arranged on the moving clamping hand 6.

[0042] In the embodiment, as shown in Figure 2 and Figure 3 , the fixed up-down driving device 5 is a pneumatic cylinder, and the fixed clamping hand 4 in the same feeding device is connected with the output end of the fixed up-down driving device 5, so as to conveniently drive the fixed clamping hand 4 to move up and down. It should be known by those skilled in the art that for the up-down movement of two or more fixed clamping hands 4 in the same feeding device, one fixed up-down driving device 5 can be used for synchronous driving or two or more fixed up-down driving devices 5 can be used for separate driving, which is mainly designed according to the needs. In the embodiment, the number of fixed up-down driving devices 5 in the same feeding device is equal to the number of fixed clamping hands 4, that is, each group of fixed clamping hands 4 is driven by a separate fixed up-down driving device 5, each fixed clamping hand 4 is connected with the output end of the corresponding fixed up-down driving device 5, and each fixed clamping hand 4 is connected with the output end of the corresponding fixed up-down driving device 5 through a fixed connecting plate 20.

[0043] In the embodiment, as shown in Figure 2As shown, the moving up and down drive device 7 is also a cylinder, and the moving grippers 6 in the same feeding device are connected to the output end of the moving up and down drive device 7; the moving up and down drive device 7 is installed on the corresponding moving front and rear drive device 8. As for the number of the moving up and down drive devices 7, for the up and down movement of more than two groups of moving grippers 6 in the same feeding device, one moving up and down drive device 7 can be used to synchronously drive or two or more moving up and down drive devices 7 can be used to drive separately. In this embodiment, in the same feeding device, one moving up and down drive device 7 is selected to synchronously drive all the moving grippers 6, that is, the moving grippers 6 in the same feeding device are respectively connected to one moving up and down drive device 7, so that the movements of each moving gripper 6 can be more synchronized. Specifically, the moving grippers 6 in the same feeding device are respectively connected to a fixed connecting plate 20, and the fixed connecting plate 20 is connected to the moving up and down drive device 7.

[0044] In this embodiment, if Figure 7 As shown, the straightening up and down drive device 10 is a pneumatic cylinder; the straightening up and down drive device 10 is installed on the straightening left and right drive device 11, and the output end of the straightening up and down drive device 11 is connected to the straightening clamp 9. Specifically, the output end of the straightening up and down drive device 11 is connected to the cylinder body of the pneumatic finger 14 of the straightening clamp 9 through a movable plate for fixing. The above arrangement can conveniently realize the up and down movement of the straightening clamp 9.

[0045] In this embodiment, if Figure 2 and Figure 3 As shown, the front-back moving drive device 8 is a linear module, and the upper and lower moving drive device 7 is mounted on the slider of the linear module; similarly, the left-right straightening drive device 11 is also configured as a linear module, and the upper and lower straightening drive device 10 is mounted on the slider of the linear module. The above configuration makes it possible to provide linear power more stably by configuring both the front-back moving drive device 8 and the left-right straightening drive device 11 as linear modules. However, those skilled in the art should know that the front-back moving drive device 8 and the left-right straightening drive device 11 can also use cylinders or other devices that can provide linear power.

[0046] The specific operating principle of the present invention is described below to facilitate a detailed understanding of the present invention. For ease of description, the following examples illustrate the following: a first feeding device is provided with two sets of fixed grippers and two sets of movable grippers, a second feeding device is provided with two sets of fixed grippers and one set of movable grippers, and a straightening device is provided with one set of straightening grippers.

[0047] refer to Figure 9First, a feeding mechanism 22 is provided at the front end of the hose feeder mechanism. This mechanism primarily provides the hose to be processed. Meanwhile, corresponding mechanisms cooperating with the hose feeder mechanism, such as a head melting mechanism, a punching mechanism, and a connector assembly mechanism, are provided at corresponding locations on the side of the hose feeder mechanism.

[0048] A plurality of hoses 21 are pre-placed on the feeding mechanism 22, and a plurality of material picking positions equal to the number of the gripper bodies of the mobile gripper 6 are provided on the feeding mechanism 22. For example, when the number of the gripper bodies in the mobile gripper 6 is one, the mobile gripper 6 will pick up a hose 21 from a corresponding material picking position each time. After the equipment is started, the first feeding device 2 is activated, and the front and rear driving devices 8 are moved to drive the mobile clamping hand 6 to move forward until the clamping hand body in the first group of mobile clamping hands 6 is aligned with the first end of the hose 21 in the feeding mechanism 22. Then, the upper and lower driving devices 7 are moved to drive the mobile clamping hand 6 to rise and insert it into the material picking position of the feeding mechanism 22 and use the corresponding pneumatic fingers 14 to drive the clamping hand body to clamp the first end of the hose 21. Then, when the front and rear driving devices 8 and the upper and lower driving devices 7 drive the mobile clamping hand 6 to move backward to the preset position, that is, when the first end of the hose 21 moves to above the first group of fixed clamping hands 4, the fixed upper and lower driving devices 5 drive the first group of fixed clamping hands 4 to rise, and make the clamping hand body use the pneumatic fingers 14 to clamp the first end of the hose 21 near the end. At this time, the outer punching mechanism can be used to punch the first end of the hose 21. After the operation is completed, the punching mechanism resets. After the mobile clamping hand 6 releases the hose 21, the front and rear driving devices 8 continue to drive the mobile clamping hand 6 to move forward so that the mobile clamping hand 6 of the first group can clamp a new hose 21 on the feeding mechanism 22. At this time, the mobile clamping hand 6 of the second group just moves to the fixed clamping hand 4 of the first group. Then the mobile clamping hand 6 of the second group drives the clamping hand body through the pneumatic fingers 14 to clamp the first end of the hose 21 of the punched fixed clamping hand 4 in the first group, and the fixed clamping hand 4 in the first group then releases the hose 21. Then, under the drive of the mobile up and down driving device 8 and the mobile front and rear driving device 9, the two groups of mobile clamping hands 6 are driven to move backward to the preset position and are clamped by the corresponding two fixed clamping hands 4 under the drive of the fixed up and down driving device 5. At this time, the hose 21 in the fixed clamping hand 4 of the second group can use the outer melting head mechanism to perform the melting head operation on the first end of the hose 21. After the operation is completed, the melting head mechanism is reset;

[0049] The straightening device 1 is in operation. First, the straightening upper and lower driving device 10 drives the straightening clamping hand 9 to move downward to the first end of the hose 21 and clamps the first end of the hose 21 with the clamping hand body. Then, the straightening left and right driving device 11 is in operation, driving the straightening clamping hand 9 to move toward the second feeding device 3. The clamping hand body is simultaneously used to limit the position of the hose 21 during movement and straighten the hose 21, that is, to pull it into a horizontal shape. When the clamping hand body moves to the end close to the first end of the hose 21, it stops. At this time, the second end of the hose 21 is located directly above the movable clamping hand 6 in the second feeding device 3 and the fixed clamping hand 4 of the first group.

[0050] The second feeding device 3 is in action. First, the fixed up and down driving device 5 drives the fixed clamping hand 4 to rise and makes the clamping hand body clamp the second end of the hose 21 with the pneumatic fingers 14. Then the straightening device 1 and the first feeding device 2 release the hose 21 in turn and reset; then, the moving up and down driving device 8 of the second feeding device 3 drives the mobile clamping hand 6 to rise and makes the clamping hand body clamp the second end of the hose 21 with the pneumatic fingers 14, and then the fixed clamping hand 4 releases the hose 21; the moving front and back driving device 8 drives the mobile clamping hand 6 to move backward to the second group of fixed clamping hands 4. At this time, the fixed up and down driving device 5 of the second group of fixed clamping hands 4 drives the corresponding fixed clamping hand 4 to rise, and makes the fixed clamping hand clamp the second end of the hose 21 with the pneumatic fingers 14. At the same time, the mobile clamping hand 6 releases the hose. At this time, the joint assembly mechanism can be used to assemble the joint on the second end of the hose 21. After the joint assembly is completed, the hose 21 can be taken away by other manipulators.

[0051] After the above steps, the feeding process of the hose 21 is completed. The hose 21 can be continuously fed by simply repeating the above corresponding steps.

[0052] In summary, (1) the present invention can clamp the two ends of the hose in sequence during one feeding of the hose by means of the mutually coordinated straightening device, the first feeding device and the second feeding device, thereby preventing the hose from swinging and affecting the processing, thereby facilitating the subsequent separate processing of the two ends of the hose and improving the processing efficiency to a certain extent; wherein, the first feeding device is used to clamp the first end of the hose, the straightening device is used to straighten the hose after the first end of the hose is processed, preventing the second feeding device from being unable to accurately clamp the second end of the hose due to bending, and the second feeding device Used to clamp the second end of the hose after the straightening device straightens the hose; (2) The present invention does not adopt the design of the first feeding device and the second feeding device clamping both ends of the hose at the same time, but adopts the design of the first feeding device clamping the first end of the hose, then using the straightening device to straighten the hose, and finally cooperating with the second feeding device to clamp the second end of the hose. This design can also prevent incomplete processing due to the different lengths of the hoses, thereby ensuring the processing yield; (3) At the same time, the present invention can also realize the automatic feeding of various hoses, thereby ensuring the feeding efficiency.
