DETAILED DESCRIPTION

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1-3 A new type of steel sheet gluing equipment is shown, including an upper mold 1, a lower mold 2 and an indentation mechanism 3. The lower mold 2 is fixed on a base 4, and the upper mold 1 is fixed on the lower side of a hydraulic press (not shown) above the base 4. The upper mold 1 is located directly above the lower mold 2 and can move back and forth up and down under the drive of the hydraulic press.

[0019] like Figure 3As shown, a punch head 11 is fixed at the center of the lower side of the upper mold 1, and a forming hole 21 is opened in the center of the lower mold 2, which runs through the upper and lower parts, and the forming hole 21 matches the punch head 11. Four guide rods 12 are vertically fixed at the four corners of the lower mold 2, and the upper mold 1 is connected to the guide rods 12 through the guide sleeve, so as to realize the limit of the upper mold 1 and the lower mold 2 and ensure the accuracy of stamping.

[0020] like Figure 1-3 As shown, a horizontal steel belt channel 22 is provided in the middle of the lower mold 1, and a horizontal adhesive belt channel 23 is provided at the bottom of the lower mold 1. The steel belt channel 22 and the adhesive belt channel 23 are arranged vertically, and the forming hole 21 is located at the intersection of the steel belt channel 22 and the adhesive belt channel 23. A steel belt 5 is passed through the steel belt channel 22, and the steel belt 5 moves stepwise along the steel belt channel 22 through a steel belt conveying mechanism (not shown). Preferably, an adjustment groove is provided on the side of the steel belt channel 22, and an adjustment member 24 is slidably installed in the adjustment groove. The inner end of the adjustment member 24 extends into the steel belt channel 22 and abuts against the side of the steel belt 5, which is used to adjust the position of the steel belt 5 to prevent the steel belt 5 from running off.

[0021] like Figure 1-3 As shown, the tape channel 23 is located at the bottom of the lower mold 2, and the tape 6 is moved stepwise along the tape channel 23 by a tape conveying mechanism (not shown). The tape 6 includes a base film and rubber particles 61 fixed in an array on the base film. The steel strip 5 is punched by the punch head 11 and the forming hole 21 to form a steel sheet 51, and the steel sheet 51 is pressed on the rubber particles 61. The shape of the rubber particles 61 is the same as that of the steel sheet 51, and the rubber particles 61 are retracted relative to the steel sheet 51 to avoid overflow of glue during pressing.

[0022] like Figure 1-3 As shown, the feeding end of the adhesive tape 6 is fixed with an indentation mechanism 3, which is composed of a group of upper pressing rollers 31 and lower pressing rollers 32 parallel to each other, and the distance between the upper pressing rollers 31 and the lower pressing rollers 32 is less than the thickness of the adhesive tape 6. Among them, an annular embossing is arranged on the roller surface of the upper pressing roller 31, and the annular embossing is distributed in an axial array along the upper pressing roller 31. When in use, the indentation mechanism 3 presses a dent on the rubber particle 61, so that the bubbles between the rubber particle 61 and the steel sheet 51 can overflow along the dent during attachment, avoiding the generation of bubbles. Preferably, the surface of the upper pressing roller 31 is sprayed with an anti-stick coating made of polytetrafluoroethylene material to prevent the upper pressing roller 31 from adhering to the rubber particle 61 and causing the rubber particle 61 to deviate and cause poor attachment.

[0023] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0024] By arranging an indentation mechanism at the feeding end of the tape to press out a dent on the tape, the air between the steel sheet and the adhesive can be discharged along the dent during adhesive application, thus avoiding the generation of bubbles, improving the product yield and reducing the production cost.
