Detailed implementation manners

[0047] The present invention will be further described below in conjunction with the drawings.

[0048] As Figures 1 to 8As shown in the figure, the threading and cutting device of the present invention is used to thread the first material 24 onto the second material 52, and includes: a working platform 17; a fixing structure arranged on the working platform 17, and the second material 52 is detachably arranged on the fixing structure. When threading the first material 24 onto the second material 52, the worker places the second material 52 on the fixing structure manually or by means of a robotic arm, etc., and uses the fixing structure to limit the second material 52 in multiple degrees of freedom, so as to ensure that the second material 52 does not move relatively during the threading process of the first material 24; a threading structure arranged on the working platform 17, and the threading structure can drive the first material 24 to move freely along a preset threading path on the second material 52; a cutting structure 8 arranged on the working platform 17, and after the first material 24 is threaded along the threading path, the cutting structure 8 can cut the first material 24 or cut the first material 24 and the second material 52, so as to complete the threading and filling of the second material 52 and then cut the threaded second material 52 to an appropriate length by using the cutting structure 8, and at the same time cut off the first material 24, so as to prepare for the next threading, and at the same time separate the unthreaded part of the first material 24 from the threaded part of the first material 24. The threading and cutting structure 8 further includes a frame, on which the working platform 17 is formed, and a cabinet door, a door handle, a guard plate, a transparent acrylic plate and a bottom corner are also arranged on the frame. The guard plate, the transparent acrylic, the cabinet door and the floor feet are respectively fixed to the corresponding parts of the structural frame for supporting and protecting the whole inside of the equipment, and the door handle is fixed to the cabinet door for facilitating the opening and closing of the cabinet door.

[0049] The fixing structure includes two strip-shaped members, the two strip-shaped members are arranged in parallel on the working platform 17, and a receiving groove is formed between the two strip-shaped members. The second material 52 is arranged in the receiving groove, and the shape of the receiving groove is the same as that of the second material 52, so as to effectively fix the second material 52. Preferably, the shapes of the second material 52 and the receiving groove are both strip-shaped.

[0050] The strip-shaped member includes a plurality of fixing blocks 51 arranged in parallel. Each fixing block 51 abuts against the second material 52, and the fixing blocks 51 of the two strip-shaped members correspond to each other one by one, that is, the second material 52 is fixed at multiple points by using a plurality of fixing blocks 51, so as to complete the fixing of the second material 52. There is a spacing between two adjacent fixing blocks 51 on the same strip-shaped member, providing an operating space for the receiving groove of the second material 52.

[0051] The threading structure includes a moving mechanism 61, a lifting mechanism, and a traction member 64. The moving mechanism 61 is disposed on the working platform 17. The lifting mechanism is disposed on the moving mechanism 61, and the lifting mechanism can move freely along the threading path on the working platform 17 driven by the moving mechanism 61. The traction member 64 is disposed on the lifting mechanism, and the traction member 64 can approach or move away from the first object driven by the lifting mechanism. When threading the first material 24 is required, the lifting mechanism lowers the traction member 64 onto the first material 24 and locks it to the first material 24 to complete the fixation. Then the moving mechanism 61 starts to move, driving the lifting mechanism, the traction member 64, and the end of the first material 24 to move together, so as to move the first material 24 along the threading path in the second material 52 and finally complete the threading. When it is necessary to take out the second material 52, the lifting mechanism raises the traction member 64 to a position away from the first material 24, thus facilitating the taking out of the second material 52 that has been threaded.

[0052] The moving mechanism 61 includes a first driving member, a first slide rail 66, and a first slider 67. The first slide rail 66 is disposed on the working platform 17. The first slider 67 is disposed on the first slide rail 66, and the first slider 67 can move freely relative to the first slide rail 66 driven by the first driving member. The shape of the first slide rail 66 is the same as the shape of the threading path in the second material 52, so as to ensure that the first material 24 can be threaded along the threading path.

[0053] The lifting mechanism includes a threading support 62 and a second driving member 63. The threading support 62 is disposed on the first slider 67. The second driving member 63 is disposed on the threading support 62, and the traction member 64 can approach or move away from the first material 24 driven by the second driving member 63. The second driving member 63 and the traction member 64 are suspended above the working platform 17 by the threading support, facilitating the lifting and lowering of the traction member 64.

[0054] The number of the moving mechanisms 61 is two. The two moving mechanisms 61 are arranged in parallel. The fixing structure is disposed between the two moving mechanisms 61. The threading support 62 is in an inverted U shape, and the two ends of the inverted U shape are respectively disposed on the two movings. The second driving member 63 is disposed on the bottom edge of the inverted U shape, ensuring that the traction member 64 will not shift during the movement and ensuring the reliability of the threading process.

[0055] One end of the traction member 64 facing the first material 24 is provided with a thimble 65. When the moving mechanism 61 drives the first material 24 to move, the thimble 65 abuts against the first material 24; or the thimble 65 penetrates into the first material 24, and the tip of the thimble 65 abuts against or penetrates into the first material 24, so as to ensure that the first material 24 can move smoothly along with the traction member 64.

[0056] The working platform 17 has opposite top and bottom surfaces. The fixing structure and the threading structure are both arranged on the top surface, the cutting structure 8 is arranged on the bottom surface, a cutting hole 171 is arranged on the working platform 17, and the cutting structure 8 cuts the first material 24 or the first material 24 and the second material 52 through the cutting hole 171, that is, to avoid interference of the cutting structure 8 on the fixing structure and the first material 24 or the second material 52, and at the same time, the structure of the working platform 17 can be fully utilized to reduce the occupied space of the threading and cutting device, and at the same time, the cutting effect on the first material 24 or the first material 24 or the second material 52 can be ensured.

[0057] The cutting structure 8 includes a cutting scissors 86 and a third driving member 83. The third driving member 83 is arranged on the bottom surface. The first end of the cutting scissors 86 is arranged on the third driving member 83. The second end of the cutting scissors 86 penetrates through the cutting hole 171 and is exposed on the top surface. And the third driving member 83 can drive the cutting scissors 86 to move freely in the cutting hole 171, and the part of the cutting scissors 86 exposed on the top surface is used to perform a movement perpendicular to the first material 24, so as to complete the cutting.

[0058] The cutting structure 8 further includes a fourth driving member 81. The fourth driving member 81 is arranged on the bottom surface. The third driving member 83 is arranged on the fourth driving member 81, and the fourth driving member 81 can drive the cutting scissors 86 to extend into or withdraw from the cutting hole 171. During the process of placing the second material 52, it is avoided that the cutting scissors 86 cause harm to the workers, and the part of the cutting scissors 86 exposed on the top surface is retracted to the bottom surface by using the fourth driving member 81, and at the same time, it is also convenient to correct and replace the cutting scissors 86.

[0059] The threading and cutting device further includes a guiding and fixing block 53. The guiding and fixing block 53 corresponds to the fixing structure one by one, and the cutting hole 171 is arranged between the guiding and fixing block 53 and the corresponding fixing structure. The guiding and fixing block 51 is used to guide the first material 24 that is about to enter the second material 52, which is convenient for the first material 24 to pass through to the second material 52, or to guide and fix the part of the second material 52 that needs to be cut, so as to avoid problems such as the second material 52 shifting during the cutting process.

[0060] The threading and cutting device further includes a positioning structure 7, which is arranged on one side of the fixed structure, and the first end face of the second material 52 located in the fixed structure abuts against the positioning structure 7, so as to ensure that the second material 52 can be accurately placed at a preset position, ensure the automation during the threading process, and avoid the need for manual participation.

[0061] The end of the threading path is located on the first end face of the second material 52, and when the threading of the first material 24 is completed, the end of the first material 24 abuts against the positioning structure 7, that is, when the threading of the second material 52 is completed, the end of the first material 24 can be exposed on the first end face of the second material 52. In order to ensure the neatness of the first material 24 and the second material 52, the end of the first material 24 should not protrude from the first end face of the second material 52.

[0062] The positioning structure 7 includes a baffle 71 and a fifth driving member 74. The fifth driving member 74 is arranged on the working platform 17, the baffle 71 is arranged on the fifth driving member 74, and the baffle 71 can be adjusted to a distance from the fixed structure under the drive of the fifth driving member 74. The positioning of the second material 52 is realized by the abutment of the baffle 71 and the second material 52. At the same time, the fifth driving member 74 can adjust the position of the baffle 71, so as to facilitate the adjustment of the size of the second material 52. Especially in cooperation with the cutting structure 8, the cutting position of the cutting structure 8 on the second material 52 can be controlled.

[0063] The positioning structure 7 further includes a second slide rail 75, a second slide block 72 and a second locking member 73. The second slide rail 75 is arranged on the working platform 17, the second slide block 72 is slidably arranged on the second slide rail 75, the second locking member 73 is arranged on the second slide block 72, and the second locking member 73 can lock the second slide block 72 on the second slide rail 75. The fifth driving member 74 is arranged on the slide block. The movable length of the baffle 71 is increased by the second slide block 72 and the second slide rail 75, so as to increase the applicable range of the threading and cutting structure 8, and the second locking member 73 can fix the second slide block 72, so as to ensure that the baffle 71 will not move.

[0064] The threading and cutting device further includes a pressing structure 4, which is arranged on the working platform 17, and the pressing structure 4 is located on the side of the cutting structure 8 away from the fixed structure. When the cutting structure 8 cuts the first material 24, the pressing structure 4 can press the first material 24 onto the working platform 17, avoiding the problem that the first material 24 moves under the influence of the cutting structure 8 during the cutting process, and ensuring the threading effect and the reliability of the next threading process.

[0065] The pressing structure 4 includes a pressing block 43 and a sixth driving member 42. The sixth driving member 42 is disposed on the working platform 17, and the pressing block 43 is disposed on the sixth driving member 42. The pressing block 43 can approach or move away from the first material 24 driven by the sixth driving member 42. When the threading structure drives the first material 24 to move, the sixth driving member 42 drives the pressing block 43 to move away from the first material 24, facilitating the movement of the first material 24. During cutting, the sixth driving member 42 can drive the pressing block 43 to press the first material 24, ensuring the reliability of cutting. Preferably, the pressing block 43 is located above the first material 24, and the sixth driving member 42 can drive the pressing block 43 to lift or lower.

[0066] The pressing structure 4 further includes a pressure-receiving block 55. The pressure-receiving block 55 is disposed below the pressing block 43, and the pressing block 43 can press the first material 24 onto the pressure-receiving block 55, using the pressure-receiving block 55 to lift the first material 24 to a height at which it can penetrate into the second material 52, thus facilitating the threading cooperation between the first material 24 and the second material 52.

[0067] The threading and cutting device further includes a feeding structure 2. The feeding structure 2 is disposed on one side of the working platform 17 and can convey the first material 24 onto the working platform 17, thus avoiding manual feeding of the first material 24.

[0068] The feeding structure 2 includes a fixed roller 22 and a feeding bracket 21. The fixed roller 22 is rotatably disposed on the feeding bracket 21, and the first material 24 is wound around the fixed roller 22.

[0069] The feeding structure 2 further includes a material tray 23. The material tray 23 is detachably disposed on the fixed roller 22, and the material tray 23 can rotate with the fixed roller 22. The first material 24 is wound around the material tray 23. Workers only need to replace the material tray 23 already wound with the first material 24 on the fixed roller 22, minimizing the operations of workers.

[0070] The threading and cutting device further includes a guiding structure 3. The guiding structure 3 is disposed on the working platform 17, and the first material 24 on the feeding structure 2 moves onto the working platform 17 under the guiding action of the guiding structure 3.

[0071] The guiding structure 3 includes a guiding wheel 32 and a guiding wheel bracket 31. The guiding wheel bracket 31 is arranged on the working platform 17, and the guiding wheel 32 is rotatably arranged on the guiding wheel bracket 31. The first material 24 on the feeding structure 2 moves onto the working platform 17 under the guiding action of the guiding wheel 32. By using the rotation of the guiding wheel 32, the moving direction of the first material 24 can be changed, so that the feeding structure 2 can be placed at the position of the working platform 17, avoiding the danger of workers having to lift the material tray 23. At the same time, the guiding wheel 32 can make the first material 24 parallel to the working plane, facilitating the threading of the first material 24.

[0072] The number of the fixing structures is multiple, and all the fixing structures are arranged side by side on the working platform 17. The threading structure and the cutting structure 8 cooperate with all the fixing structures correspondingly. That is, multiple second materials 52 are arranged on one working platform 17 at the same time, and multiple corresponding first materials 24 are arranged for threading. Thus, the threading process of multiple second materials 52 can be completed in one action of the threading structure. At the same time, the cutting structure 8 can also complete the cutting of multiple first materials 24 or the first materials 24 and the second materials 52, improving the production efficiency.

[0073] The threading and cutting device further includes a control mechanism and a pressing structure 4. The control mechanism is electrically connected to the threading structure, the cutting structure 8 and the pressing structure 4. Preferably, the control mechanism includes a display screen, and workers can directly control the actions of the threading structure, the cutting structure 8 and the pressing structure 4 through the display screen.

[0074] The first material 24 is a sealing strip, and the second material 52 is a reinforcing strip.

[0075] Preferably, the first driving member, the second driving member 63, the third driving member 83, the fourth driving member 81, the fifth driving member 74 and the sixth driving member 42 are all cylinders, or the first driving member is a moving module.

[0076] Taking the first material 24 as the sealing strip and the second material 52 as the reinforcing strip as an example, the operator needs to first pass the sealing strips in the feeding part (material tray 23) through the guiding structure 3, the pressure block 55 in the threading structure, and the guiding and fixing block 53 in sequence, and make the end head part of the sealing strip flush with one end of the guiding and fixing block 53. The operator places the reinforcing strip on the fixing block 51 for positioning. At the same time, the operator adjusts the position of the baffle 71 of the positioning structure 7. The sixth driving member 42 is in the extended position, so that the baffle 71 is in full contact with the reinforcing strip to achieve the positioning of one end of the reinforcing strip. Among them, by adjusting the position of the second slider 72, the gap between the other end of the reinforcing strip and one end of the guiding and fixing block 53 is 2-3 mm. At this time, the baffle 71 of the positioning structure 7 is positioned by the second locking member 73. Then, the threading structure moves to the initial position of threading the sealing strip under the drive of the first driving member. The sixth driving member 42 retracts, and the pressing block 43 disengages from the sealing strip. At the same time, the second driving member 63 extends, and one end of the ejector pin 65 presses on the end head part of the sealing strip. Under the drive of the first driving member, the sealing strip is threaded along the threading path on the reinforcing strip. Then, the threading structure threads the sealing strip to the in-place state to complete the threading of the sealing strip (that is, the ends of the sealing strip and the reinforcing strip both abut against the baffle 71). At this time, the sixth driving member 42 of the pressing structure 4 extends, so that the pressing block 43 presses the sealing strip onto the pressure block 55 to achieve the pressing of the sealing strip. Then, the fourth driving member 81 of the cutting structure 8 extends, so that the cutting scissors 86 are on one side of the sealing strip. Then, the fifth driving member 74 extends to drive the cutting scissors 86 to move horizontally, so as to realize the cutting of the sealing strip. At this time, the threading and cutting actions of the sealing strip have been completed. The threading structure moves to the initial position of threading the sealing strip under the drive of the first driving member. The sixth driving member 42 of the pressing structure 4 lifts, and the pressing block 43 disengages from the sealing strip. The fourth driving member 81 of the cutting structure 8 drives the fifth driving member 74 and the cutting scissors 86 to move, so that the cutting scissors 86 return to the initial position of cutting. At this time, the reinforcing strip has been threaded with the sealing strip. The operator takes the finished product out of the accommodating groove and puts in the next batch of reinforcing strips. Then the device repeats the above actions to realize the threading and cutting of the sealing strip for the next batch of reinforcing strips, realizing the automation of the threading and cutting of the sealing strip.

[0077] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention.
