[0035] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0036] See Figures 1 to 5The utility model provides a sealing tape attaching device for attaching sealing tape to products, including a control box body 1 and a fixed platform 2 provided on the control box body 1, the fixed platform 2 is provided with a positioning groove 21 for placing the product 100, and the control box body 1 is also provided with a first attaching module 3 and a second attaching module 4, the first attaching module 3 and the second attaching module 4 are respectively arranged on the sides of the opposite ends of the fixed platform 2, the first attaching module 3 is used to attach tape to one side of the attaching end of the product 100, and the second attaching module 4 is used to attach tape to the other side and side of the attaching end when the product 100 is flipped so that its attaching end is located on the side of the second attaching module 4. Among them, the first attachment module 3 includes a flap 31 and a pressure plate 32, one side of the flap 31 is hinged on the control box body 1, and one side of the pressure plate 32 is slidably connected to the flap 31 through a sliding assembly 33, so that the pressure plate 32 can be pressed down vertically; the second attachment module 4 includes a pressure plate assembly slidably connected to the control box body 1, and a driving assembly for driving the pressure plate assembly to be able to squeeze horizontally, the pressure plate assembly is a 7-shaped structure composed of a horizontal drag plate 41 and a vertical squeezing plate 42, and the lower surface of the horizontal end of the 7-shaped structure can slide against the other side of the product 100.

[0037] Specifically, the application of the sealing tape to the product 100 is carried out in two steps:

[0038] ① Place the attachment end of the product 100 on the positioning groove 21 toward the side of the first attachment module 3. The flap 31 of the first attachment module 3 is flipped to drive the pressure plate 32 to press vertically downward to attach the tape to one side of the attachment end of the product 100 (that is, what is conventionally referred to as attaching the tape with part of the tape overlapping), and then take out the product 100.

[0039] In this step, the pressing plate 32 exerts downward pressure on the tape to make it adhere to the product. At the same time, the tape in contact with the edge of the product forms a fold line consistent with the edge. Combined with the characteristics of the tape itself, the remaining part of the tape bends downward under the action of the fold line (see Figure 6 (The green line represents the product outline, and the red line represents the tape after step 1). The tape remains in this state. The tape can bend downward because the tape attachment size during this step is less than half the tape, allowing the remaining tape to droop naturally under its own weight.

[0040] ② Turn the product 100 of step ① over so that its attachment end faces the second attachment module 4 and place it on the positioning groove 21. At this time, the surface of the adhesive tape attached in step ① is placed on the bottom side (i.e. Figure 6The tape is in the opposite state, tilted outward and upward), and the horizontal drag plate 41 and the vertical extrusion plate 42 of the second attaching module 4 cooperate with each other to apply a horizontal force to the tape close to the product so that the tape is attached to the side and the other side of the product, even if the tape forms a U-shape at the edge of the product (see Figure 7 , the green line is the product outline, and the red line is the completed tape).

[0041] Furthermore, the flap 31 is provided with a through-slot 311, and the pressure plate 32 is provided with a pressure block 321 that matches the through-slot 311. The pressure block 321 is provided with multiple vacuum holes 3211 that can absorb the tape and keep it within the through-slot 311. Hinge shafts 312 are provided on both sides of the end of the flap 31 away from the pressure plate 32, and the control box body 1 is provided with a hinge seat 34 that matches the hinge shafts 312. The flap 31 is provided with a first connecting block 313. The sliding assembly 33 includes a slide groove 331 vertically provided on the side of the first connecting block 313 facing the pressure plate 32, and a sliding block 332 provided on the pressure plate 32 and slidably engaged with the slide groove 331.

[0042] As can be understood, the through slot 311 is adapted to the size of the tape, and the non-adhesive side of the tape is directed toward the pressing block 321, and the tape is adsorbed by the vacuum adsorption hole 3211. Therefore, the pressing plate 32 is pressed downward to drive the tape on the pressing block 321 to move downward synchronously, so that the tape is partially attached to the product (see Figure 6 state); in addition, by arranging a sliding component 33 between the pressing plate 32 and the flip plate 31, the pressing plate 32 can be pressed down vertically, so that the tape is attached vertically downward to the product, ensuring the uniformity and accuracy of the attachment position; the vacuum adsorption hole 3211 is connected to the air source and the air source control unit 6 controls the attachment pressure of the pressing plate 32 on the tape and the pressure holding time to ensure the firmness of the tape attachment and the formation of creases.

[0043] Among them, the gas source control unit 6 and the gas source pipeline connecting the gas components and the gas source (not shown in the figure) are the same as the existing technology. The gas source control unit 6 can have functions such as gas source input or shutdown, air pressure detection, pressure holding time, alarm (buzzer), etc., which will not be repeated here.

[0044] Furthermore, stoppers 35 are provided on either side of the end of the flap 31 near the pressure plate 32 to limit the upward movement of the pressure plate 32, ensuring that the adhesive tape can be placed within the through-slot 311 without adhering to it. Multiple guide shafts 36 and return springs 38 are positioned between the pressure plate 32 and the flap 31. One end of the guide shaft 36 is fixed to the flap 31, and the other end is slidably connected to the pressure plate 32 via a sleeve 37. Return springs 38 are positioned adjacent to the guide shafts 36. The guide shafts 36 and return springs 38 between the pressure plate 32 and the flap 31 further ensure the vertical downward pressure of the pressure plate 32, while preventing hard contact between the pressure plate 32 and the product surface during downward pressure. After the adhesive tape is applied, the return springs allow the pressure plate 32 to reset itself.

[0045] For further information, see Figure 4 , define the direction in which the piston rod of the cylinder 43 extends closer to the product as the front, and the direction in which the piston rod is retracted away from the product as the rear; the horizontal drag and pressure plate 41 is slidably set on the vertical extrusion plate 42 through the second sliding component 411, and the vertical extrusion plate 42 is set on the control box body 1 through the first sliding component 423, and the vertical extrusion plate 42 is driven by the cylinder 43 to drive the horizontal drag and pressure plate 41 forward at the same time, and when the vertical extrusion plate 42 attaches the tape to the side of the product, the horizontal drag and pressure plate 41 continues to move forward to push the remaining part of the tape forward while attaching it to the other side of the product. Here, the action of the horizontal drag and pressure plate 41 is controlled by the air source control unit 6. It is understandable that since the tape is in an upward and outward tilted state, when the horizontal drag and pressure plate 41 and the vertical extrusion plate 42 move forward at the same time, the front end of the horizontal drag and pressure plate 41 preferentially approaches the upper end of the tape. Therefore, the horizontal drag and pressure plate 41 forms a support for the upper end of the tape, so that when the front end of the vertical extrusion plate 42 approaches the tape, the tape can be in a flat state to be attached to the side of the product.

[0046] Specifically, the vertical extrusion plate 42 includes a push-pull plate 421 and a pressure member 422 located on the side of the push-pull plate 421 facing the product 100. The pressure member 422 is adapted to the side of the attachment end of the product 100 and is made of silicone, which facilitates pressurizing the tape without damaging it. A guide slope 412 is provided on the lower side of the end of the horizontal drag-pull plate 41 facing the fixed platform 2. This allows the upper end of the tape to first contact the front end of the horizontal drag-pull plate 41 and then gradually bend using the guide slope 412, thereby maintaining a flat surface and gradually attaching the tape to the other side of the product. A cylinder 43 is located on the side of the horizontal drag-pull plate 41 away from the fixed platform 2. The piston rod of the cylinder 43 is connected to the push-pull plate 421 via a connector 431. The first sliding assembly 423 includes two first guide rails 4231 disposed on the control box body 1, arranged parallel and spaced apart from each other, and a first slider 4232 disposed on the underside of the push-pull plate 421 and slidably connected to the first guide rails 4231. The second sliding assembly 411 includes two second guide rails 4111 disposed on the upper side of the push-pull plate 421 and arranged in the same direction as the first guide rails 4231, and a second slider 4112 disposed on the underside of the horizontal drag and pressure plate 41 and slidably connected to the second guide rails 4111. The arrangement of the sliding assembly ensures the smooth movement of the horizontal drag and pressure plate 41 and the vertical extrusion plate 42, thereby ensuring the quality of tape application.

[0047] Furthermore, the device is also provided with a pressurizing component 5, which is arranged on a side close to the second attaching module 4, and includes a support 51 and a pressurizing plate 52. The support 51 is provided on either side of the other two sides of the fixed platform 2, and one end of the pressurizing plate 52 is hinged to the support 51 so that the pressurizing plate 52 can be flipped over and pressed onto the upper surface of the product 100 on the fixed platform 2. The pressurizing plate 52 is provided with a waist-shaped hole 521 at the end away from its hinged end, and a positioning column 22 is provided on the fixed platform 2 corresponding to the waist-shaped hole 521. When the pressurizing plate 52 is pressed onto the product, the positioning column 22 is inserted into the waist-shaped hole 521 to fix the pressurizing plate 52, so as to ensure the stability of the product on the fixed platform 2. In addition, two silicone pads 522 are provided at intervals on the side of the pressurizing plate 52 facing the fixed platform 2 (see Figure 1 The blue part is shown in the middle. When the pressure plate 52 is in the pressing state, the two silicone pads 522 on it are pressed against the product and the fixed platform 2 at the same time (see Figure 5 The product 100 and the fixed platform 2 are at the same height, which ensures the quality of the tape attachment without damaging the product.

[0048] To sum up, the sealing tape attaching device provided by the utility model is provided with tape attaching modules on both sides of the fixed platform for positioning the product, wherein the first attaching module uses the method of flipping and pressurizing, which not only enables the tape to be firmly attached to the attaching end of the product, but also uses the edge of the product to bend the tape during the pressurizing process, and then flips the product to utilize the mutual cooperation between the horizontal drag and pressure plate and the vertical extrusion plate of the second attaching module to achieve the sealing attachment of the tape; the fixed platform is used to position the product to prevent the quality problem of tape attachment caused by product instability during the tape attachment process; the first attaching module uses vacuum adsorption to transfer the tape to the product, ensuring the uniformity and accuracy of the attachment position, as well as the firmness of the tape; the structure is simple, the tape attachment efficiency is high, and the attachment quality of the product is improved.
