[0021] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples and cannot be used to limit the protection scope of the present invention.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0023] The suction-type tape attaching mechanism of the embodiment of the present invention is applied to an automatic tape reeling machine (such as Figure 6 The automatic tape winding machine is used for automatically winding the material tape, and includes a frame 1, a paper tape unwinding mechanism 2, a tape unwinding mechanism 3, a control system 4, a material tape conveying mechanism 5, a material tape winding mechanism 6 and a tape sticking mechanism 7, etc. The winding reel is positioned on the material tape winding mechanism 6, and the control system 4 controls the various mechanisms to coordinate and orderly move to realize the material tape winding, wherein the tape sticking mechanism 7 adopts the adsorption-type tape sticking mechanism in the above-mentioned embodiment 1. The use of the adsorption-type tape sticking mechanism can effectively bond the tape to the winding reel to fix the end of the paper tape.

[0024] The adsorption type tape attachment mechanism in this embodiment is described in detail below. Figures 1 to 5As shown, it includes a mounting base 70, a pushing mechanism 71 and a suction block 72. The pushing mechanism 71 is mounted on the mounting base 70. The suction block 72 is driven to move forward and backward by the pushing mechanism 71, thereby driving the suction block 72 to approach and move away from the winding disk. The front part of the suction block 72 has an adsorption surface 721 for adsorbing the adhesive tape. The adsorption surface 721 is provided with an air suction hole 720. A connecting cavity 725 is provided in the suction block 72. The connecting cavity 725 is communicated with the air suction hole 720, and the connecting cavity 725 is connected to a negative pressure source. When the negative pressure source draws air, the adhesive tape can be adsorbed on the adsorption surface 721. When the adhesive tape needs to be detached from the adsorption surface 721, the suction force of the suction block 72 on the adhesive tape disappears when the negative pressure source is controlled to stop drawing air. More specifically, the suction block 72 includes a support block 726 and a surface block 727. The support block 726 and the surface block 727 can be fixedly connected using bolts. 726 is fixedly connected to the pushing mechanism 71, the support block 726 can be a metal block (such as a stainless steel block, an iron block), or an engineering plastic block, the surface block 727 is made of elastic rubber material and is fixed to the front of the support block 726, the front end surface of the surface block 727 is set as a plane and serves as the adsorption surface 721, and the suction hole 720 is set through the surface block 727; since the surface block 727 is made of elastic rubber material, the adsorption surface 721 can be elastically deformed when under pressure, and the support block 726 is made of a metal block or a plastic block to provide effective support for the surface block 727 and can be reliably connected to the pushing mechanism 71; in normal state, the adsorption surface 721 is a plane to adapt to the flat adsorption of the tape, and when the surface block 727 presses the tape on the reel, the adsorption surface 721 can better adapt to the shape of the reel, so that the tape is more fully attached to the reel, thereby ensuring the bonding strength between the tape and the reel.

[0025] Further, if Figure 3As shown, a plurality of mounting holes are connected and arranged at corresponding positions on the support block 726 and the surface block 727. The mounting holes are arranged along the movable direction of the suction block 72 (i.e., the front-to-back direction). A positioning pin 728 is inserted in the mounting hole so as to be movable back and forth. The positioning pin 728 has a limiting block 7281 limited in the mounting hole. The limiting action of the limiting block 7281 can prevent the positioning pin 728 from escaping from the mounting hole. A pressure spring 729 is arranged in the mounting hole to apply a forward elastic force to the positioning pin 728. Under the elastic force of the pressure spring 729, the needle tip 7282 at the front end of the positioning pin 728 extends out of the adsorption surface 721. When the adhesive tape is adsorbed by the adsorption surface 721 and adhered to the paper tape, the needle tip 7282 can pierce the adhesive tape and the paper tape adhered to it, thereby strengthening The adhesive tape and the paper tape are connected on the adsorption surface 721 to prevent them from falling off when the adhesive tape and the paper tape are adhered to each other and when the suction block 72 drives the adhesive tape and the paper tape to move toward the winding disk; since the positioning pin 728 can be extended and retracted forward and backward, when the needle tip 7282 abuts against the corresponding part of the winding disk, it will push the positioning pin 728 to slide into the mounting hole and compress the pressure spring 729. When the needle tip 7282 is separated from the winding disk, the positioning pin 728 moves forward and resets under the elastic force of the pressure spring 729; the outer diameter of the limit block 7281 is larger than the outer diameter of other parts of the positioning pin 728, and the limit block 7281 is preferably set at the rear end of the positioning pin 728 to increase the rear end surface of the positioning pin 728, so as to better adapt the positioning pin 728 to the abutment with the pressure spring 729 and the positioning pin 724. In order to improve the performance of the positioning pin 728, it can be made of carbide or stainless steel; the mounting hole is provided with a limiting sliding hole that slides with the limiting block 7281, and the aperture of the limiting sliding hole is larger than the aperture of the mounting hole. The steps formed at both ends of the limiting sliding hole play a role of resisting and limiting the limiting block 7281, thereby limiting the movable stroke of the positioning pin 728.

[0026] Continue to view Figure 3In order to ensure that the needle tip 7282 of the suction block 72 protrudes from the adsorption surface 721 and pierces the tape and the paper tape when the suction block 72 is in the initial position, a positioning pin 724 arranged along the front-to-back direction is relatively fixed on the mounting base 70, and the positioning pin 724 is opposite to the mounting hole. When the suction block 72 is in the initial position, the front end of the positioning pin 724 is inserted from the rear port of the mounting hole and abuts against the rear end of the positioning pin 728, so that the needle tip 7282 protrudes from the adsorption surface 721. In this state, the positioning pin 724 provides effective support for the positioning pin 728 to prevent the positioning pin 728 from retracting into the mounting hole; when the suction block 72 moves toward the winding disk and leaves the initial position, the positioning pin 724 withdraws from the mounting hole, and then the positioning pin 728 can move toward the mounting hole. Furthermore, an elastic compensation element (not shown in the figure) can be added between the positioning pin 724 and the positioning needle 728. The elastic compensation element can be deformed under pressure, such as by using a rubber ring or a polytetrafluoroethylene sheet. The elastic compensation element can play a role in gap compensation, thereby avoiding the situation where the positioning pin 724 cannot effectively support the positioning needle 728 due to a gap between the positioning pin 724 and the positioning needle 728 when the suction block 72 is in the initial position due to insufficient assembly accuracy, and can also reduce impact and vibration. The elastic compensation element is fixed to the front end of the positioning pin 724, or to the rear end of the positioning needle 728, to prevent the elastic compensation element from falling off when the positioning pin 724 is separated from the positioning needle 728.

[0027] Exemplarily, a thread is provided at the rear end of the positioning pin 724, and a threaded hole is provided on the positioning block 711 described below, and the positioning pin 724 is fixed to the positioning block 711 by a threaded connection. At the same time, the positioning pin 724 can be screwed to make its position adjustable in the front and rear directions, thereby having good practicality.

[0028] In this embodiment, it is preferred to set the pressure spring 729 as a coil spring. This spring has good elasticity and stability and can provide uniform and continuous elastic force. The pressure spring 729 is arranged along the front-to-back direction and its two ends are respectively abutted against the limit block 7281 and the step in the mounting hole, thereby providing a forward elastic force for the positioning pin 728. The positioning pin 724 passes through the inner cavity of the pressure spring 729 and abuts against the rear end of the positioning pin 728. In order to facilitate the installation of the positioning pin 728 and the pressure spring 729 into the support block 726, it is preferred to set the support block 726 as a split combination structure. The split combination structure can simplify the installation and maintenance process. By dividing the support block 726 into several parts and assembling them together, it is easier to form the required mounting hole, and it is convenient to install the positioning pin 728 and the pressure spring 729 into the mounting hole and to carry out subsequent maintenance.

[0029] like Figure 5As shown, in the further optimization of the present embodiment, a positioning groove 7261 can be provided on the side of the support block 726 facing the dough block 727, a pressure sensor 7262 is embedded in the positioning groove 7261, the pressure sensor 7262 is connected to the control system of the automatic tape reel, and a contact block 7271 is fixed on the dough block 727 at a position corresponding to the pressure sensor 7262, when the pushing mechanism 71 drives the suction block 72 to move toward the winding disk, and when the dough block 727 contacts the corresponding part of the winding disk, the adsorption surface 721 of the dough block 727 is compressed to produce adaptive deformation and the contact block 7271 contacts the pressure sensor 7262, and the pressure data is transmitted to the control system of the automatic tape reel, when the pressure reaches the preset value, the control system controls the pushing mechanism 71 to stop the action, so that the activity stroke of the suction block 72 can be flexibly controlled to ensure that the adhesive tape effectively bonds the paper tape to the winding disk, which has better practicality.

[0030] Preferably, a petal (not shown in the figure) protruding toward the center is provided on the inner hole wall at the front end of the suction hole 720, and at least three petals are evenly distributed along the circumference, preferably four or five petals are provided, and each petal is a fan-shaped thin sheet structure, the petals are made of the same elastic rubber material as the dough block 727, and are integrally formed with the dough block 727, so that the structure and production process can be simplified. Under normal circumstances, the petals can block the inside of the suction hole 720 to prevent dust and foreign matter from entering the suction hole 720. When the negative pressure source draws air, the petals are affected by the suction force and deformed backwards, making the front end of the suction hole 720 fully open to accommodate the adsorption of the tape; after the negative pressure disappears, the petals can return to their original state and continue to play a role in blocking dust and foreign matter.

[0031] Combination Figures 1 to 3As shown, the pushing mechanism 71 includes a positioning block 711, a guide sleeve 712, a support slide rod 713, a driving screw rod 714, a screw nut 715 and a servo motor device 716; the positioning block 711 is fixed to the front end of the mounting base 70, the guide sleeve 712 and the screw nut 715 are fixed to the positioning block 711, at least two support slide rods 713 are arranged through the guide sleeve 712 to provide stable support for the forward and backward movement of the suction block 72, and can provide effective support for the servo motor device 716, the driving screw rod 714 is arranged through the screw nut 715, the front end of the support slide rod 713 is fixedly connected to the support block 726, and the front end of the driving screw rod 714 is rotatably connected to the support block 726 through a bearing; the rear ends of at least two support slide rods 713 are connected through a fixed block 717, the rear end of the driving screw rod 714 is rotatably connected to the fixed block 717 through a bearing, and the servo motor device 716 is fixed to the fixed block 717. On the fixed block 717, the servo motor device 716 drives the driving screw rod 714 to rotate. When the servo motor device 716 drives the driving screw rod 714 to rotate, the driving screw rod 714 moves forward and backward along the axial direction through the cooperation between the driving screw rod 714 and the screw nut 715, thereby driving the suction block 72 connected thereto to move forward and backward (while the servo motor device 716 moves forward and backward together), and the cooperation between the guide sleeve 712 and the support slide rod 713 plays a role of limiting guide and support to ensure the linearity and stability of the movement of the suction block 72; the above-mentioned pushing mechanism 71 is reasonably arranged, the structure is simple and feasible, and the operation is stable; and by installing the servo motor device 716 at the rear, the space occupied at the front end of the pushing mechanism 71 can be saved, which is also conducive to the arrangement and installation of components such as the paper tape cutting mechanism 12 and the paper tape pressing mechanism 13; and this structure also helps to combine the pushing mechanism 71 and the suction block 72 into an integral module for easy installation and debugging.

[0032] Exemplarily, the servo motor device 716 includes a servo motor, pulley one, pulley two and a transmission belt, wherein pulley one is fixed to the rear end of the driving screw 714, pulley two is fixed to the output shaft of the servo motor, and the transmission belt is sleeved on pulley one and pulley two, so that when the servo motor drives pulley two to rotate, pulley one is driven to rotate through the transmission belt, thereby driving the driving screw 714 to rotate. In this way, the installation position of the servo motor can be set more flexibly to avoid conflicts in the installation position.

[0033] Combination Figure 2 and Figure 3As shown, the support slide bar 713 has a cavity that runs through the axial direction, one end of the cavity is connected to the connecting cavity 725, and the other end is equipped with an air pipe connector 718. The air pipe connector 718 is connected to the negative pressure source through a pipeline, and a solenoid valve is provided on the pipeline. The tape can be adsorbed on the adsorption surface 721 by suctioning air through the negative pressure source; when the tape needs to be detached from the suction block 72, the solenoid valve is controlled to be closed, and the suction force between the suction block 72 and the tape will disappear; by setting the cavity of the support slide bar 713 as one section of the entire suction pipeline, and setting the air pipe connector 718 at the rear end of the support slide bar 713, the air pipe is not directly connected to the suction block 72, the pipeline layout is optimized, the complexity of the pipeline is reduced, and the problem of the air pipe being suspended when the suction block 72 moves forward when the suction block 72 is directly connected to the air pipe is avoided; the air pipe connector can adopt a quick-connect connector, which is convenient for quick connection and disassembly of the air pipe and provides convenience for maintenance.

[0034] In some embodiments, see Figure 1 and Figure 4 As shown, the adsorption-type taping mechanism also includes a paper tape pressing mechanism 13 and a paper tape cutting mechanism 12 installed on the mounting base 70. The paper tape pressing mechanism 13 and the paper tape cutting mechanism 12 are driven by the driving unit to move between the front side position of the adsorption surface 721 and the position deviated from the front side of the adsorption surface 721. When working, the paper tape pressing mechanism 13 presses the paper tape toward the adsorption surface 721, thereby bonding the paper tape with the adhesive tape adsorbed on the adsorption surface 721. The paper tape cutting mechanism 12 is used to cut the paper tape after the tail end of the paper tape is bonded to the adhesive tape; after the paper tape is bonded to the adhesive tape and the paper tape is cut, the driving unit drives the paper tape pressing mechanism 13 and the paper tape cutting mechanism 12 to deviate from the position in front of the adsorption surface 721, so as not to interfere with the forward and backward movement of the suction block 72.

[0035] Furthermore, combined with Figure 1 and Figure 4 As shown, the paper tape pressing mechanism 13 includes a plurality of tapes along the width direction of the adsorption surface 721 (i.e. Figure 2 The first pressing mechanism 131 and the second pressing mechanism 132 are arranged at intervals (in the direction indicated by the arrow L in the middle), the paper tape cutting mechanism 12 is arranged between the first pressing mechanism 131 and the second pressing mechanism 132, and the adsorption surface 721 has a first adsorption area 722 suitable for corresponding to the position of the first pressing mechanism 131 and a second adsorption area 723 suitable for corresponding to the position of the second pressing mechanism 132 in its width direction; in actual operation, the adhesive tape is adsorbed on the entire adsorption surface 721, and the paper tape is transported to the adsorption surface 721 and passes through the first pressing mechanism 131 and the second pressing mechanism 132 to press the head and tail of the paper tape toward the first adsorption area 722 and the second adsorption area 723 respectively, so that the corresponding ends of the paper tape are bonded to the adhesive tape in the first adsorption area or the second adsorption area, and the part of the tape not bonded with the paper tape is used to bond with the winding disk.

[0036] like Figure 4 As shown, the driving unit includes a mounting frame 14, a lifting cylinder 15, a lifting seat 16, a lifting seat 2 18 and a lifting cylinder 2 17; the mounting frame 14 is fixed on the mounting base 70, the lifting seat 16 and the lifting seat 2 18 can be lifted and moved on the mounting frame 14 and are driven by the lifting cylinder 15 and the lifting cylinder 2 17 respectively; the first pressing mechanism 131 and the second pressing mechanism 132 are both installed on the lifting seat 16, the paper tape cutting mechanism 12 is installed on the lifting seat 2 18, and the paper tape cutting mechanism 12 can use pneumatic scissors to control the blades of the pneumatic scissors to cut the paper tape when the blades are closed; the first pressing mechanism 131 and the second pressing mechanism 132 have the same structure and both include a transverse cylinder 133 fixed on the lifting seat 16, a cylinder driven by the transverse cylinder 133, and a pressure relief valve 134. The pressure plate 134 is close to and far away from the adsorption surface 721. The lifting cylinder 15 drives the lifting seat 16 to rise so that the position of the pressure plate 134 is raised. The lifting cylinder 2 17 drives the lifting seat 2 18 to rise so that the pneumatic scissors 1 position is raised, so as not to interfere with the forward and backward telescopic movement of the suction block 72; when the lifting cylinder 15 drives the lifting seat 16 to descend, the position of the pressure plate 134 is lowered and is located in front of the adsorption surface 721, so that the paper tape can be pressed. When the lifting cylinder 2 17 drives the lifting seat 2 18 to descend, the pneumatic scissors 1 position is lowered and is located in front of the adsorption surface 721 to adapt to cutting the paper tape; more specifically, the pressure plate 134 and the needle tip 7282 are provided with avoidance holes 135 at the corresponding positions. When the pressure plate 134 presses the paper tape and the tape on the adsorption surface 721, the avoidance holes 135 can avoid the needle tip 7282.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
