Description

Technical Field

[0001] The present invention relates to a laminating device, in particular to an automatic laminating device used in adhesive production. Background Art

[0002] During the PCB adhesive lamination process, a laminating device is required. This device is typically equipped with a cutter. When the adhesive is supplied in roll (or strip) form (such as self-adhesive stickers, foam adhesive, or double-sided tape), the device must cut the continuous roll into individual pieces of a specified length before laminating. The cutter's function is to cut the adhesive roll to the specified size, ensuring a consistent adhesive length each time it is applied.

[0003] In adhesive lamination design, the extent to which the adhesive width extends beyond the PCB (referred to as "width") needs to be dynamically adjusted based on factors such as the severity of the operating environment and the priority of functional requirements. However, the cutters on existing lamination equipment are typically fixed, requiring replacement of cutters of different sizes during use to adjust the adhesive cutting width. Summary of the Invention

[0004] The main purpose of the present invention is to provide an automatic laminating device for adhesive production, which can cut adhesives of different sizes without stopping the machine.

[0005] In order to achieve the above-mentioned object, the present invention provides an automated laminating device for adhesive production, comprising a drive device and a cutter, wherein the drive device is used to drive the cutter to move downward, the drive device is fixedly connected to the top of the cutter, and the cutter comprises a mounting seat, an outer cutter, and an inner cutter, the mounting seat is slidably connected to the top of the outer cutter, a first pneumatic device is provided in the mounting seat, and a second pneumatic device is provided inside the outer cutter: When the outer cutter is in the working state, the lower portion of the outer cutter is located in the first position, and the outer cutter is in the working position, the inner cutter is located inside the outer cutter, the first pneumatic device is in the inflated state, and the second pneumatic device is in the contracted state; When the inner cutter is in working state, the first pneumatic device is in contraction state, the outer cutter is in second position, the second pneumatic device is in inflation state, and the bottom height of the inner cutter is flush with the first position.

[0009] More preferably, a second slide bar is provided on the top of the inner cutter, the top of the second slide bar passes through the outer cutter, and the second slide bar is slidably connected to the outer cutter.

[0010] Preferably, an upper groove is provided on the top of the external cutting knife, and the bottom of the mounting seat is slidably arranged in the upper groove.

[0011] Further preferably, an inner groove is provided at the bottom of the mounting seat, and the first pneumatic device is arranged in the inner groove.

[0015] The beneficial effects of the present invention are: 1. Improve production efficiency and reduce equipment downtime No need to change cutters: Traditional equipment requires shutdown to replace cutters of different sizes to adjust the adhesive width. However, this device uses a pneumatic device to control the switching between the external cutter and the internal cutter (for example, the external cutter cuts large adhesives, while the internal cutter cuts small adhesives). The cutting width can be adjusted in real time during the production process without stopping the machine, significantly improving production continuity.

[0018] Wide-width scenarios: When the circuit board requires high protection (such as waterproof and dustproof), the wide adhesive strip can be cut with an external cutter to ensure full edge coverage. Small and wide-width scenarios: When the PCB size is compact or cost-sensitive, the adhesive backing can be cut into narrow widths using an internal cutter to reduce material waste.

[0019] 3. Precisely control cutting size: The cutting edge design of the outer and inner cutters ensures a neat cutting edge, avoiding burrs or dimensional deviations. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figure 1 As shown, this embodiment provides an automated laminating device 1 for use in adhesive backing production, including a drive device 2 and a cutter 3. The drive device 2 is used to drive the cutter 3 to move downward, and the drive device 2 is fixedly connected to the top of the cutter 3. In this embodiment, the drive device 2 can adopt a cylinder, a hydraulic cylinder, etc., and is set according to the actual situation of the equipment.

[0025] Specifically, in this embodiment, Figure 2 As shown, the cutter 3 includes a mounting seat 100, an outer cutter 210 and an inner cutter 220. The mounting seat 100 is slidably connected to the top of the outer cutter 210, and the top of the mounting seat 100 is fixedly connected to the telescopic rod of the driving device 2.

[0026] like Figure 3 and Figure 4 As shown, a first pneumatic device 130 is provided in the mounting base 100. Preferably, an upper groove 213 is provided on the top of the outer cutter 210, and the bottom of the mounting base 100 is slidably provided in the upper groove 213. An inner groove 110 is provided at the bottom of the mounting base 100, and the first pneumatic device 130 is provided in the inner groove 110. The rise and fall of the outer cutter 210 is controlled by controlling the inflation and contraction state of the first pneumatic device 130. Specifically, as shown in FIG. Figure 5As shown, the first pneumatic device 130 includes a first upper mounting plate 131, a first airbag 133, and a first lower mounting plate 132. One side of the first upper mounting plate 131 is fixedly connected to one side of the first airbag 133, while the other side of the first upper mounting plate 131 is fixedly connected to the top of the inner groove 110. The other side of the first airbag 133 is fixedly connected to one side of the first lower mounting plate 132, while the other side of the first lower mounting plate 132 is fixedly connected to the bottom of the upper groove 213 of the inner cutter 220. The first air pipe 120 connects the first airbag 133 to the air pump, enabling rapid inflation and deflation. When the first airbag 133 is inflated, it is in a taut state.

[0027] In order to more accurately control the movement of the outer cutting knife 210, a first sliding rod 140 is provided at the bottom of the inner groove 110. The top of the first sliding rod 140 passes through the mounting seat 100, and the first sliding rod 140 is slidably connected to the mounting seat 100.

[0028] In this embodiment, if Figures 6 to 10 As shown, a lower groove 212 is provided at the bottom of the outer cutter 210, and the inner cutter 220 is located within the lower groove 212 and is slidably connected to the outer cutter 210. A second pneumatic device 230 is located between the inner cutter 220 and the top of the lower groove 212, connecting the outer cutter 210 and the inner cutter 220 via the second pneumatic device 230. Specifically, in this embodiment, the second pneumatic device 230 includes a second upper mounting plate 231, a second airbag 233, and a second lower mounting plate 232. One side of the second upper mounting plate 231 is fixedly connected to one side of the second airbag 233, the other side of the second upper mounting plate 231 is fixedly connected to the top of the lower groove 212, the other side of the second airbag 233 is fixedly connected to one side of the second lower mounting plate 232, and the other side of the second lower mounting plate 232 is fixedly connected to the inner cutter 220. A second air pipe 234 is used to connect the second airbag 233 to the air pump to achieve rapid inflation and deflation. When the second airbag 233 is in the inflated state, the second airbag 233 is in a tense state.

[0029] Similarly, in order to more accurately control the movement of the inner cutter 220, a second slide bar 240 is provided at the top of the inner cutter 220. The top of the second slide bar 240 passes through the outer cutter 210, and the second slide bar 240 is slidably connected to the outer cutter 210.

[0030] The specific usage method of this embodiment is: When the outer cutter 210 is in operation, the lower portion of the outer cutter 210 is in the first position (i.e., the operating position, in which the drive device 2 drives the outer cutter 210 downward to cut the adhesive), the inner cutter 220 is located within the outer cutter 210, and the inner cutter's cutting edge 221 is lower than the outer cutter's cutting edge 211. At this time, the first pneumatic device 130 is inflated, and the second pneumatic device 230 is in a deflated state. The adhesive cut by the outer cutter 210 is larger than the width of the circuit board.

[0031] When the inner cutter 220 is in operation, the first pneumatic device 130 is in a retracted state. At this time, the outer cutter 210 is in the second position, and the cutting edge 211 of the outer cutter moves upward, higher than the first position. The second pneumatic device 230 is in an inflated state, and the bottom of the inner cutter 220 is flush with the first position, so that the inner cutter 220 is in the operating position of the first position. In this way, the stroke of the drive device 2 remains unchanged.

[0032] In this embodiment, the outer side of the outer cutting blade 211 is flush with the outer wall of the outer cutting blade 210, and the inner side of the inner cutting blade 221 is flush with the inner wall of the inner cutting blade 220. Since the inner cutting blade 221 is set inward, the width of the adhesive at the cutting position is substantially the same as the width of the circuit board.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
