Description

Technical Field

[0001] The invention relates to a hose automatic assembly device, in particular to a vehicle oil can hose automatic assembly device. Background Art

[0002] The installation of the hose of the vehicle oil tank usually includes two steps. The first step is to connect the hose to the connector first, and then connect the hose to the oil tank. At present, it is assembled manually with hand-held tools, which is time-consuming, labor-intensive, and inefficient. There is a risk of clamping the hose when using tools, and the angle and length of the assembled hose are inaccurate. In order to solve the above problems, people have designed an automatic hose assembly device that can automatically assemble the hose to the connector first, and then automatically assemble the hose to the oil tank, which improves efficiency compared to manual assembly.

[0003] However, the automatic hose assembly equipment in the prior art often has many problems during use, such as: only one hose can be placed at a time, and multiple hoses cannot be placed, resulting in low work efficiency; the same type of connector sometimes requires different installation angles, that is, the connector needs to be adjusted at an angle before the hose is inserted during assembly. In order to achieve assembly at multiple angles on one device, it is necessary to use tooling with multiple different inclination angles. During disassembly and assembly, the screws need to be removed first, and then the tooling needs to be replaced, and the downward pressure cylinder used in conjunction also needs to adjust the angle, which is time-consuming and labor-intensive; after the hose and the connector are assembled, they need to be removed manually and then placed on another assembly table, and they cannot be removed and transferred automatically, which also leads to low work efficiency; after the hose and the oil can are assembled, they need to be pulled out from the assembly table manually, which also leads to low work efficiency.

DETAILED DESCRIPTION

[0030] In order to more intuitively and completely understand the technical solution of the present invention, a non-limiting feature description is now provided in conjunction with the accompanying drawings of the present invention as follows:

[0031] like Figure 1 — Fig. 9As shown, the automatic hose assembly equipment includes a frame 1, on the top of which are installed a first hose placement mechanism 2, a joint assembly mechanism 3, a second hose placement mechanism 4 and an oil pot assembly mechanism 5, a hose 6 is placed on the first hose placement mechanism 2, a joint 7 is placed on the joint assembly mechanism 3, the joint assembly mechanism 3 drives the joint 7 to move, and the hose 6 and the joint 7 are assembled together, the hose 6 with the joint 7 is placed on the second hose placement mechanism 4, the oil pot 8 is placed on the oil pot assembly mechanism 5, the oil pot assembly mechanism 5 drives the oil pot 8 to move, and the oil pot 8 and the hose 6 are assembled together; the first hose placement mechanism 2 includes a turntable 201 and a plurality of loading platforms 202 uniformly distributed along the circumference on the top of the turntable 201, and the hose 6 is placed on the loading platform 202; the joint assembly mechanism 3 is located in front of the first hose placement mechanism 2, the joint assembly mechanism 3 includes a joint placement platform 301 and a first rotating cylinder 302 for driving the joint placement platform 301 to rotate, and the joint 7 is placed on the joint placement platform 301; the top of the frame 1 is installed with a plurality of loading platforms 202 located between the first hose placement mechanism 2 and the joint assembly mechanism 3. The second hose placement mechanism 4 is located on the left side of the first hose placement mechanism 2, and the second hose placement mechanism 4 includes a fixed platform 401 and a movable platform 402 distributed on the left and right. The right end of the fixed platform 401 has a groove 4011 for placing the hose 6 with the connector 7 installed. The hose 6 with the connector 7 is stuck between the fixed platform 401 and the movable platform 402. The movable platform 402 is connected to a driving device for driving it to move left and right. The left end of the movable platform 402 is provided with a driving device for driving it to move left and right. It is equipped with multiple retractable squeezing devices for squeezing the outer wall of the hose 6; the oil pot assembly mechanism 5 is located in front of the second hose placement mechanism 4, and the oil pot assembly mechanism 5 includes an oil pot placement platform 501, the upper end of the oil pot placement platform 501 has a slot 5011 for the oil pot 8 to be inserted, and the oil pot placement platform 501 is installed with an ejection mechanism 10 that can move up and down and is used to push the oil pot 8 upward; the rear middle position of the top of the frame 1 is installed with a manipulator 11 for transferring the hose 6 with the connector 7 installed to the groove 4011 of the fixed platform 401. The connector 7 is aligned with one end of the hose 6, and the oil inlet of the oil pot 8 is aligned with the other end of the hose 6.

[0032] like Figure 2As shown, the first hose placement mechanism 2 includes a first bracket 203 fixed on the top of the frame 1, a rotating motor 204 fixed on the top of the first bracket 203, and the output shaft of the upper end of the rotating motor 204 is fixed to the turntable 201; the first hose placement mechanism 2 also includes a second bracket 205 fixed on the outside of the first bracket 203 and a first downward pressure cylinder 206 installed on the upper end of the second bracket 205 extending up and down, and the piston rod end of the lower end of the first downward pressure cylinder 206 is fixed with a first pressing plate 207 located above the loading platform 202. After the rotating motor 204 is started, it will drive the turntable 201 to rotate. When a hose 6 on a loading platform 202 is used, the turntable 201 rotates one station. When the first downward pressure cylinder 206 is working, it can control the first pressing plate 207 to move downward and press the hose 6 to prevent the hose 6 from falling when docking with the connector 7.

[0033] like Figure 3 As shown, the joint assembly mechanism 3 includes a third bracket 303, a first rotating cylinder 302 is fixed on the front lower end of the third bracket 303, a joint placement platform 301 is fixed on the front end of the first rotating cylinder 302, a second rotating cylinder 304 is fixed on the front upper end of the third bracket 303, a second pressing cylinder 305 extending up and down is fixed on the front end of the second rotating cylinder 304, and a second pressing plate 306 located above the joint placement platform 301 is fixed to the piston rod end of the lower end of the second pressing cylinder 305. When the second pressing cylinder 305 is working, it can control the second pressing plate 306 to press the joint 7, and when the first rotating cylinder 302 is working, it can drive the joint placement platform 301 to rotate, so the angle of the joint 7 can be adjusted, so the joint placement platform 301 does not need to be removed and replaced, and the second rotating cylinder 304 is used to control the angle of the second pressing plate 306, and is used in conjunction with the rotated joint 7, so that the second pressing plate 306 can have a precise angle to contact the joint 7. As shown Figure 1 , Figure 3 As shown, the joint assembly mechanism 3 also includes a first base 307 fixed on the top of the frame 1, a first slide rail 308 fixed on the top of the first base 307 extending forward and backward, and a first slide 309 that slides forward and backward with the first slide rail 308, a third bracket 303 is fixed on the top of the first slide 309, and a first motor 310 is installed at the front end of the first base 307, and the first motor 310 is connected to a first screw rod assembly 311, and the first screw rod assembly 311 is connected to the bottom of the first slide 309 and is used to drive the first slide 309 to move forward and backward. After the first motor 310 is started, it can drive the first slide 309 to move forward and backward, so the joint 7 can move forward and backward. Because the joint placement platform 301 is inclined, the joint 7 needs to be firmly stuck on the upper end of the joint placement platform 301 to prevent it from falling.

[0034] like Figure 4As shown, the tube pulling mechanism 9 includes a lifting cylinder 901 fixed on the top of the frame 1 extending up and down, a lifting platform 902 fixedly connected to the top of the second slide 9011 on the outside of the lifting cylinder 901, and a finger cylinder 903 fixed on the top of the lifting platform 902, and the finger cylinder 903 is located below the hose 6 with the connector 7 installed. When the hose 6 and the connector 7 are assembled together, the lifting cylinder 901 controls the finger cylinder 903 to move upward, and the finger cylinder 903 clamps the hose 6. The lifting cylinder 901 controls the finger cylinder 903 to continue to move upward, and the hose 6 is moved out of the loading platform 202, and the connector 7 is moved out of the connector placement platform 301. Because the hose 6 is stuck on the loading platform 202, and the connector 7 is stuck on the connector placement platform 301, both are stuck tightly. After the tube pulling mechanism 9 "pulls out" the hose 6 and the connector 7, it is convenient for the manipulator 11 to transfer them.

[0035] like Figure 5 , Figure 6 As shown, the second hose placement mechanism 4 includes a fourth bracket 403 fixed on the top of the frame 1, a track 404 extending left and right is fixed on the top of the fourth bracket 403, and the movable platform 402 slides left and right with the track 404. The driving device is a driving cylinder 405 fixed on the right end of the fourth bracket 403, and the piston rod end of the left end of the driving cylinder 405 is fixedly connected with a fixed block 406, and the fixed block 406 is fixedly connected to the top of the movable platform 402. The driving cylinder 405 can control the movable platform 402 to move left and right. When the movable platform 402 moves to the left and is close to the fixed platform 401, the hose 6 will be stuck between the fixed platform 401 and the movable platform 402. Figure 7 As shown, each extrusion device includes a sleeve 407, a spring 408 and a steel ball 409. The sleeve 407 has a receiving groove 4071, and the left end of the receiving groove 4071 is open. The spring 408 is fixed in the receiving groove 4071 extending left and right. The steel ball 409 is pressed on the left end of the spring 408, and the left end of the steel ball 409 is exposed outside the sleeve 407. The steel ball 409 is used to squeeze the outer wall of the hose 6. After the steel ball 409 squeezes the outer wall of the hose 6, the hose 6 is pressed tightly to prevent the hose 6 from falling when it is connected to the oil pot 8. When the hose 6 needs to be removed, the driving cylinder 405 controls the movable platform 402 to move to the right, and the hose 6 is freed from the restraint of the movable platform 402 and the steel ball 409, thereby facilitating the removal of the hose 6.

[0036] The left end of the movable platform 402 has threaded holes (not shown in the figure) equal in number to the sleeve 407, and the outer wall of the sleeve 407 has external threads (not shown in the figure). The sleeve 407 is screwed into the threaded holes by threaded connection, that is, the extrusion device is easy to disassemble and assemble. In addition, because the hose 6 has different hardnesses due to different materials during manufacturing, the position of the extrusion device needs to be adjusted for hoses 6 of different hardnesses, and the depth of the sleeve 407 screwed into the threaded hole needs to be adjusted. When the hose 6 is soft, the sleeve 407 does not need to be screwed very deep, that is, the steel ball 409 can be exposed more, so that the hose 6 can be better pressed. On the contrary, when the hose 6 is hard, the sleeve 407 can be screwed deeper.

[0037] like Figure 1 , Figure 8 As shown, the oil pot assembly mechanism 5 also includes a support plate 502, a fifth bracket 503 fixed on the top of the support plate 502, and a third downward pressure cylinder 504 fixed on the upper end of the fifth bracket 503. The piston rod end of the third downward pressure cylinder 504 is fixed with a third pressing plate 505 located above the oil pot 8; the oil pot assembly mechanism 5 also includes a second base 506 fixed on the top of the frame 1, a second slide rail 507 fixed on the top of the second base 506 extending forward and backward, and a third slide 508 slidingly matched with the second slide rail 507 forward and backward. The support plate 502 is fixed on the top of the third slide 508. The front end of the second base 506 is equipped with a second motor 509, and the second motor 509 is connected to a second screw assembly 510. The second screw assembly 510 is connected to the bottom of the third slide 508 and is used to drive the third slide 508 to move forward and backward. When the second motor 509 is started, it can drive the third slide 508 to move forward and backward, so the oil pot 8 can move forward and backward.

[0038] like Fig. 9As shown, the ejection mechanism 10 includes a slide cylinder 1001 arranged in the oil pot placement platform 501 along the up-down direction, a fourth slide 10011 provided on the outside of the slide cylinder 1001 is fixedly connected to a connection platform 1002, a push rod 1003 extending up and down is fixed on the outside of the connection platform 1002, a top block 1004 is fixed on the top of the push rod 1003, and a through hole 5012 extending up and down and connected to the slot 5011 is provided in the upper end of the oil pot placement platform 501, and the through hole 5012 is for the push block 1004 and the push rod 1003 to pass through, and the push block 1004 is located below the oil pot 8. The design of the ejection mechanism 10 is intended to realize the last key step of the automated process of assembling the oil pot 8, that is, the automatic ejection and disassembly of the oil pot 8. In the automatic assembly process of the oil pot 8 and the hose 6, the oil pot 8 is usually designed to be tightly clamped into the slot 5011 (because the oil pot 8 is placed at an angle, it is easy to fall if it is not clamped). However, this tight engagement also brings troubles in disassembly, because manual disassembly requires sufficient force to overcome the engagement resistance, which is not only time-consuming and labor-intensive, but also may increase the risk of damage to the oil pot 8. The slide cylinder 1001 of the ejection mechanism 10 can control the fourth slide 10011 to move up and down when working. When the fourth slide 10011 moves upward, it can drive the ejector rod 1003 and the ejector block 1004 to move upward. When the oil pot 8 and the hose 6 are assembled, the ejector block 1004 will be accurately positioned below the oil pot 8. As the fourth slide 10011 continues to rise, the ejector block 1004 will exert an upward force to eject the oil pot 8 from the slot 5011. This process is not only fast but also accurate, which can ensure the smooth disassembly of the oil pot 8. Of course, the ejection mechanism 10 needs to be used in conjunction with the second hose placement mechanism 4 when working, because only when the movable platform 402 moves to the right and the extrusion device is separated from the hose 6, the hose 6 is freed from the restraint of the movable platform 402 and the steel ball 409, so that the hose 6 can be removed together with the oil pot 8 after the oil pot 8 is pushed upward. Because if the hose 6 is stuck, then even if the oil pot 8 is pushed upward, the hose 6 needs to be pulled out. Therefore, the movement of the movable platform 402 and the ejection action of the ejection mechanism 10 complement each other, and they jointly ensure the smooth progress of the disassembly process.

[0039] During operation, the hose 6 is manually placed on the loading platform 202 of the first hose placing mechanism 2, and the hose 6 is placed on each loading platform 202. After placement, the first pressing cylinder 206 controls the first pressing plate 207 to press down the hose 6, and the connector 7 is manually placed on the connector placing platform 301. The angle of the connector 7 is adjusted by the first rotating cylinder 302, and the angle of the second pressing plate 306 is adjusted by the second rotating cylinder 304. The second pressing cylinder 305 controls the second pressing plate 306 to press down the connector 7, and then the first motor 310 controls the first slide 309 to move backward, so that the connector 7 is inserted into one end of the hose 6, and then the first pressing plate 207 and the second pressing plate 306 move upward to reset, and the tube pulling mechanism 9 moves the hose 6 out of the loading platform 202, and moves the connector 7 out of the connector placement Platform 301, the manipulator 11 clamps the hose 6 with the connector 7 installed, the finger cylinder 903 of the tube pulling mechanism 9 releases the hose 6, the manipulator 11 puts the hose 6 with the connector 7 installed on the groove 4011 of the fixed platform 401 of the second hose placing mechanism 4, and manually clamps the oil pot 8 into the clamping groove 5011 of the oil pot placing platform 501, the third pressing cylinder 504 controls the third pressing plate 505 to press the oil pot 8, and then drives the cylinder 405 to control the movable platform 402 to move to the left, so that the steel ball 409 presses the outer wall of the hose 6, the second motor 509 controls the third slide 508 to move backward, so that the oil inlet of the oil pot 8 is inserted into the other end of the hose 6, and the third pressing cylinder 504 controls the third pressing plate 505 to move upward and reset, so that the oil pot 8 and the hose 6 are assembled together. After assembly is completed, the movable table 402 moves to the right under the action of the driving cylinder 405. This action separates the extrusion device from the hose 6, and the hose 6 is freed from the restraint. Then, the ejection mechanism 10 starts to work, and the ejector rod 1003 and the ejector block 1004 push the oil pot 8 upward out of the slot 5011. At this time, the oil pot 8 can be easily removed manually.

[0040] The first hose placement mechanism 2 of the present invention adopts a rotating disk 201 and a plurality of loading platforms 202, and can place a plurality of hoses 6 at one time, realizing continuous operation, reducing the time for replacing the hoses 6, and thus improving production efficiency;

[0041] The joint assembly mechanism 3 of the present invention can flexibly adjust the installation angle of the joint 7 through the cooperation of the first rotary cylinder 302 and the second rotary cylinder 304, without the need to replace the tooling, thus saving the time and manpower for disassembling and assembling the tooling, and improving the versatility and flexibility of the equipment;

[0042] The design of the tube pulling mechanism 9, the manipulator 11 and the oil can assembly mechanism 5 of the present invention realizes the automation of the hose 6 from assembly to transfer, reduces the inefficiency caused by manual operation, and further improves the production efficiency;

[0043] The squeezing device in the second hose placement mechanism 4 of the present invention can accurately fix the hose 6 through the design of the spring 408 and the steel ball 409, thereby ensuring the stability and accuracy of the hose 6 during the assembly process;

[0044] The ejection mechanism 10 in the oil pot assembly mechanism 5 of the present invention is used in conjunction with the movable platform 402 of the second hose placement mechanism 4, so that people can easily remove the assembled oil pot 8.

[0045] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the contents of the specification and drawings of the present invention should be included in the patent protection scope of the present invention.
