[0032] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0033] As attached Figure 1 and 2 As shown, a rubber coating device for automatic rubber coating of fiber umbrella ribs includes a fiber arrangement mechanism 1, a fiber feeding mechanism 2, a transfer mechanism 4 and a material distribution mechanism 5.

[0034] As attached Figure 2 and 3 As shown, the fiber arrangement mechanism 1 includes a fiber arrangement frame 11, a fiber placement frame 12, a lifting frame 13 and a slider 14. The fiber arrangement frame 11 is provided with a fiber placement frame 12 for placing umbrella ribs 61, and the fiber arrangement frame 11 is provided with a lifting frame 13. The lifting frame 13 is provided with a slider 14 which can slide up and down. The movement of the slider 14 can be driven by a screw mechanism arranged in the lifting frame 13. During operation, the motor on the screw mechanism drives the screw to rotate, and the screw is threadedly connected to the slider 14. The slider 14 is moved up and down along the lifting frame 13 through the threaded engagement force, thereby providing power for the subsequent movement of the fiber feeding mechanism 2 and completing the fiber suction operation of the fiber suction plate 22 on the fiber feeding mechanism 2.

[0035] As attached Figure 5 and 6 As shown, the fiber feeding mechanism 2 includes a connecting frame 21 and a fiber absorbing board 22. A connecting frame 21 is provided below the fiber absorbing board 22. The connecting frame 21 is rotatably connected to the slider 14, and the fiber absorbing board 22 can move forward and backward relative to the connecting frame 21. The movement mode of the fiber absorbing board 22 can be any driving mode that can realize movement in the prior art, such as: a screw mechanism, a cylinder push, an oil cylinder push, etc. The fiber absorbing board 22 is used to neatly arrange the ribs 61 on the fiber placement frame 12 and send them to the lower mold 31 of the mold 3 for injection molding to form an umbrella frame 6. Specifically, the fiber absorbing board 22 is a hollow board, and the surface of the fiber absorbing board 22 is used to absorb the ribs 6 1 is penetrated with a through hole, and the side of the fiber absorption board 22 is penetrated with an opening, which is connected to the suction pump through an external conduit. During operation, the suction pump is started to extract the air in the fiber absorption board 22 through the conduit and the opening, so that a negative pressure is formed in the fiber absorption board 22. At this time, the outside air will enter the fiber absorption board 22 from the through hole of the groove on the surface of the fiber absorption board 22, so that the ribs 61 are adsorbed in the groove on the surface of the fiber absorption board 22, so that the ribs 61 are neatly arranged on the fiber absorption board 22, and then the fiber absorption board 22 is moved to neatly transport the ribs 61 to the lower mold 31 of the mold 3 for injection molding to form the umbrella frame 6, without the need for manual fiber arrangement, thereby improving the processing efficiency.

[0036] Among them, as attached Figures 4 to 8As shown, the connecting frame 21 is rotatably connected to the slider 14. Specifically, a cam 131 protruding outward is provided on the surface of the lifting frame 13, and an inwardly recessed limiting groove 211 is provided on the connecting frame 21. The limiting groove 211 is in a 7-shape, and one end of the limiting groove 211 is exposed to the surface of the connecting frame 21. When the slider 14 drives the connecting frame 21 to move upward, the cam 131 is embedded in the limiting groove 211, and then the slider 14 continues to drive the connecting frame 21 to move upward. At this time, after the cam 131 moves along the limiting groove 211, the connecting frame 21 drives the fiber absorption board 22 to gradually rotate to the horizontal and move horizontally upward for a distance and then stop, and then the fiber absorption board 22 moves horizontally forward, and the U-shaped fiber absorption board 22 is inserted into the giving groove 32 on the lower mold 31 of the mold 3, and then the fiber absorption board 22 is horizontally lowered, and the suction pump stops working, and the umbrella ribs 61 neatly arranged on the fiber absorption board 22 are placed flat on the groove on the surface of the lower mold 31, and the feeding operation of the umbrella ribs 61 is automatically realized, and then the fiber absorption board 22 is reset, and the umbrella ribs 61 are injection molded on the mold 3 to form the umbrella frame 6, so as to realize the automatic feeding and loading operation of the umbrella ribs 61 on the mold 3, without manual operation, which saves labor costs on the one hand and speeds up the efficiency of injection molding and encapsulation of the umbrella ribs 61 on the other hand.

[0037] As attached Figures 9 to 11As shown, the transfer mechanism 4 includes a running base 41 and a clamp 42, the running base 41 is arranged on the fiber arrangement frame 11, and the clamp 42 is movably arranged above the running base 41. The moving mode of the clamp 42 can be any driving mode that can realize movement in the prior art, such as: screw mechanism, cylinder push, oil cylinder push, etc. The clamp 42 is used to transfer the umbrella frame 6 formed by injection molding on the mold 3 to the material distribution base 51 of the material distribution mechanism 5. Specifically, the clamp 42 includes a mounting frame 421, a movable clamp 422, a fixed clamp 423 and a truss 426. The truss The frame 426 is movably connected to the operating base 41, and the mounting frames 421 are symmetrically arranged at both ends of the truss 426. The bottom surface of the mounting frame 421 is provided with a plurality of fixed clamps 423, and the two sides of the mounting frame 421 are provided with movable clamps 422, and the movable clamps 422 can move left and right relative to the mounting frame 421. The moving mode of the movable clamps 422 can be any driving mode that can realize movement in the prior art, such as: screw mechanism, cylinder push, oil cylinder push, etc., and the moving directions of the two movable clamps 422 are opposite, and the movable clamps 422 and the fixed clamps 423 cooperate with each other to clamp the umbrella ribs 61 on the umbrella frame 6. In addition, the clamp 42 also includes a plurality of pressing blocks 427, and the pressing blocks 427 are arranged on both sides of the fixed clamps 423, and the pressing blocks 427 can move relative to the mounting frame 421. During operation, the clamp 42 is first moved so that the clamp 42 covers the umbrella frame 6 injection-molded on the mold 3. At this time, the fixed clamp 423 is inserted between the adjacent ribs 61 on the umbrella frame 6, and then the two movable clamps 422 are moved toward each other until the clamping blocks 4221 on the two movable clamps 422 are clamped and closed, and the ribs 61 are restricted between the movable clamps 422 and the mounting frame 421. Then the pressing block 427 moves downward to press the ribs 61 against the movable clamp 422, completing the fixed connection between the umbrella frame 6 and the clamp 42, preventing the umbrella frame 6 from falling off the clamp 42 during the movement of the clamp 42, thereby realizing the transportation of the umbrella frame 6.

[0038] As attached Figures 12 to 16As shown, the material distribution mechanism 5 includes a material distribution base 51 and a material distribution frame 52. The material distribution base 51 is arranged on one side of the operating base 41. The material distribution base 51 is provided with a material distribution frame 52 which can move up and down. The material distribution frame 52 is used to separate the plastic frame 62 on the umbrella frame 6 from the umbrella rib 61. Specifically, the material distribution frame 52 includes a connecting portion 521 and a material distribution hook 522. The connecting portion 521 is arranged on the material distribution base 51 and can move up and down. The moving mode of the connecting portion 521 can be any driving mode that can realize movement in the prior art, such as: screw mechanism, cylinder push, oil cylinder push, etc. A plurality of dividing hooks 522 are symmetrically provided on the upper surface of the part 521. When the umbrella frame 6 is placed on the cross frame of the dividing base 51, the dividing hooks 522 move downward to hook the plastic frame 62 suspended on the umbrella frame 6, and then the connecting part 521 drives the dividing hooks 522 to move downward. Since the ribs 61 on the umbrella frame 6 are supported by the cross frame on the dividing base 51, the dividing hooks 522 can pull the plastic frame 62 off the ribs 61 of the umbrella frame 6, so as to separate the plastic frame 62 from the ribs 61, and the ribs 61 after injection molding and encapsulation can be used independently, while the redundant plastic frame 62 formed by the injection molding track can be removed and recycled.

[0039] During operation, the fiber absorption board 22 is first driven by the slider 14 to move downward along the lifting frame 13, and the suction pump is started at the same time to extract the air in the fiber absorption board 22 through the conduit and the opening, so that negative pressure is formed in the fiber absorption board 22. At this time, the outside air will enter the fiber absorption board 22 from the through holes of the grooves on the surface of the fiber absorption board 22, so that the ribs 61 are adsorbed in the grooves on the surface of the fiber absorption board 22, and then the fiber absorption board 22 is moved upward along the lifting frame 13. In this process, a number of ribs 61 are neatly adsorbed and arranged in the grooves on the surface of the fiber absorption board 22, and the fiber arrangement of the ribs 61 is completed;

[0040] When the slider 14 drives the fiber absorption board 22 and the connecting frame 21 to move upward and approach the top of the lifting frame 13, the cam 131 will be embedded in the limiting groove 211, and then the slider 14 continues to drive the fiber absorption board 22 and the connecting frame 21 to move upward. At this time, after the cam 131 moves along the limiting groove 211, the connecting frame 21 is forced to drive the fiber absorption board 22 to gradually rotate to the horizontal and move horizontally upward for a distance and then stop, and then the fiber absorption board 22 moves forward horizontally, and the U-shaped fiber absorption board 22 is inserted into the giving groove 32 on the lower mold 31 of the mold 3, and then the fiber absorption board 22 is horizontally lowered, and the suction pump stops working, and the umbrella ribs 61 neatly arranged on the fiber absorption board 22 are placed flatly on the groove on the surface of the lower mold 31, and the feeding operation of the umbrella ribs 61 is automatically realized, and then the fiber absorption board 22 is reset, and the umbrella ribs 61 are injection molded on the mold 3 to form the umbrella frame 6, realizing the automatic feeding and loading operation of the umbrella ribs 61 on the mold 3;

[0041] After the umbrella frame 6 is formed, the clamp 42 is first moved to cover the umbrella frame 6 injection-molded on the mold 3. At this time, the fixed clamp 423 is inserted between the adjacent ribs 61 on the umbrella frame 6, and then the two movable clamps 422 are moved toward each other until the clamping blocks 4221 on the two movable clamps 422 are clamped and closed, and the ribs 61 are restricted between the movable clamps 422 and the mounting frame 421. Then the pressing block 427 is moved downward to press the ribs 61 on the movable clamp 422 to complete the fixed connection between the umbrella frame 6 and the clamp 42, so as to prevent the umbrella frame 6 from falling off the clamp 42 during the movement of the clamp 42. Then the clamp 42 is moved and rotated to transfer the umbrella frame 6 to the horizontal frame of the material distribution base 51, and the plastic frame 62 of the umbrella frame 6 is located below the material distribution hook 522, so as to complete the transfer of the umbrella frame 6.

[0042] Then, the connecting portion 521 drives the dividing hook 522 to move downward to hook the plastic frame 62 suspended on the umbrella frame 6. Since the ribs 61 on the umbrella frame 6 are supported by the cross frame on the dividing base 51, the dividing hook 522 can pull the plastic frame 62 off the ribs 61 of the umbrella frame 6, thereby separating the plastic frame 62 from the ribs 61, and the ribs 61 after injection molding and rubber coating can be used independently, while the excess plastic frame 62 formed by the injection molding track can be removed and recycled, thereby completing the rubber coating operation of the ribs 61.

[0043] The structure is simple and the operation is convenient. The fiber arrangement mechanism 1 and the fiber delivery mechanism 2 cooperate with each other to neatly arrange the ribs 61 on the fiber placement frame 12 and deliver them to the lower mold 31 of the mold 3 for injection molding to form an umbrella frame 6. The injection-molded umbrella frame 6 is then transferred to the material separation mechanism 5 through the transfer mechanism 4. The material separation mechanism 5 is used to separate the plastic frame 62 on the umbrella frame 6 from the ribs 61, and the ribs 61 after injection molding and rubber coating are used independently. The structure is compact and no manual operation is required throughout the process. On the one hand, labor costs are saved, and on the other hand, the efficiency of injection molding and rubber coating of the ribs 61 is accelerated.

[0044] A working process of a glue encapsulation device for automatic glue encapsulation of fiber umbrella ribs is characterized by being carried out in the following steps:

[0045] In the first step, the slider 14 is used to drive the fiber absorption board 22 to move downward along the lifting frame 13, and at the same time, the suction pump is started to extract the air in the fiber absorption board 22 through the conduit and the opening, so that a negative pressure is formed in the fiber absorption board 22. At this time, the outside air will enter the fiber absorption board 22 from the through holes of the grooves on the surface of the fiber absorption board 22, so that the ribs 61 are adsorbed in the grooves on the surface of the fiber absorption board 22;

[0046] In the second step, the fiber absorption board 22 is moved upward along the lifting frame 13. During this process, a plurality of ribs 61 are neatly adsorbed and arranged in the surface grooves of the fiber absorption board 22.

[0047] In the third step, when the slider 14 drives the fiber absorbing board 22 and the connecting frame 21 to move upward and approach the top of the lifting frame 13, the cam 131 will be embedded in the limiting groove 211, and then the slider 14 continues to drive the fiber absorbing board 22 and the connecting frame 21 to move upward. At this time, after the cam 131 moves along the limiting groove 211, the connecting frame 21 is forced to drive the fiber absorbing board 22 to gradually rotate to the horizontal and move horizontally upward for a distance before stopping;

[0048] The fourth step is to move the fiber absorption board 22 horizontally forward and insert the U-shaped fiber absorption board 22 into the clearance groove 32 on the lower mold 31 of the mold 3;

[0049] Step 5: Lower the fiber absorption board 22 horizontally, stop the suction pump, and place the neatly arranged ribs 61 on the fiber absorption board 22 flatly on the grooves on the surface of the lower mold 31;

[0050] Step 6: The fiber absorption board 22 is reset, and the ribs 61 are injection molded on the mold 3 to form the umbrella frame 6, so that the automatic feeding and loading operation of the ribs 61 on the mold 3 is realized;

[0051] Step 7: After the umbrella frame 6 is formed, the clamp 42 is first moved so that the clamp 42 covers the umbrella frame 6 formed by injection molding on the mold 3. At this time, the fixed clamp 423 is inserted between the adjacent ribs 61 on the umbrella frame 6.

[0052] Step 8: Move the two movable clamps 422 toward each other until the clamping blocks 4221 on the two movable clamps 422 are clamped and closed, thereby restricting the rib 61 between the movable clamps 422 and the mounting frame 421.

[0053] In the ninth step, the pressing block 427 is moved downward to press and fix the umbrella rib 61 on the movable clamp 422, thereby completing the fixed connection between the umbrella frame 6 and the clamp 42, and preventing the umbrella frame 6 from falling off the clamp 42 during the movement of the clamp 42;

[0054] Step 10: Move and rotate the clamp 42 to transfer the umbrella frame 6 to the horizontal frame of the material distribution base 51, and the plastic frame 62 of the umbrella frame 6 is located below the material distribution hook 522;

[0055] In the eleventh step, the connecting part 521 drives the dividing hook 522 to move downward to hook the plastic frame 62 suspended on the umbrella frame 6. Since the ribs 61 on the umbrella frame 6 are supported by the cross frame on the dividing base 51, the dividing hook 522 can pull the plastic frame 62 off the ribs 61 of the umbrella frame 6, thereby separating the plastic frame 62 from the ribs 61, and the ribs 61 after injection molding are used independently, while the excess plastic frame 62 formed by the injection molding track is removed and recycled, thereby completing the rubber coating operation of the ribs 61. The structure is compact and no manual operation is required throughout the process. On the one hand, labor costs are saved, and on the other hand, the efficiency of injection molding and rubber coating of the ribs 61 is accelerated.

[0056] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.

In the third step, when the fiber absorption board and the connecting frame move upward and approach the top of the lifting frame, the cam will be embedded in the limit groove and move along the limit groove. At this time, the connecting frame is driven by the force to gradually rotate the fiber absorption board to the horizontal and move horizontally upward for a distance before stopping; The fourth step is to move the fiber absorption board horizontally forward and insert the U-shaped fiber absorption board into the clearance groove on the lower mold of the mold; The fifth step is to lower the fiber absorption board horizontally, stop the suction pump at the same time, and place the neatly arranged ribs on the fiber absorption board flatly on the grooves on the surface of the lower mold; Step 6: The fiberboard is reset and the ribs are injection molded on the mold to form the umbrella frame; Step 7: After the umbrella frame is formed, the clamp is first moved so that the clamp covers the umbrella frame injection-molded on the mold. At this time, the fixed clamp is inserted between adjacent ribs on the umbrella frame. Step 8: Move the two movable clamps toward each other until the clamping blocks on the two movable clamps are clamped and closed, thereby restricting the ribs between the movable clamps and the mounting frame; Step 9: Move the pressing block downward to press and fix the ribs on the movable fixture; Step 10: Move and rotate the clamp to transfer the umbrella frame to the horizontal frame of the material distribution base, and the plastic frame of the umbrella frame is located below the material distribution hook; In the eleventh step, the connecting part drives the material dividing hook to move downward to hook the plastic frame suspended on the umbrella frame, and pull the plastic frame off the ribs of the umbrella frame to separate the plastic frame from the ribs.
