Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and in particular to a frame adhesive cutting and bonding device. Background Technology

[0002] Currently, adhesive layers are frequently used to bond two substrates of electronic devices together. These adhesive layers consist of a frame adhesive and a liquid adhesive. In the traditional bonding process, the frame adhesive is first applied to the first substrate, forming a retaining ring. Then, liquid adhesive is poured into the retaining ring formed by the frame adhesive. The frame adhesive and liquid adhesive together form the adhesive layer, and the second substrate is then bonded to the adhesive layer. For large-sized electronic devices, a large amount of liquid adhesive needs to be applied during the manufacturing process.

[0003] Before curing, the water-based adhesive is liquid and can flow. When the substrate is tilted or shaken, causing the bottom frame of the adhesive to be lower than the top frame in the vertical direction, the water-based adhesive will exert great pressure on the bottom frame due to gravity. Since gravity alone will cause the water-based adhesive to be laid incompletely, there will be dead corners in the filling and bonding, resulting in uneven bonding of the adhesive, affecting the bonding quality, and consequently causing poor appearance of electronic devices, increasing cleaning difficulty, and reducing production quality. Summary of the Invention

[0004] This invention provides a frame adhesive cutting and bonding device that improves structural reliability, ensures processing quality, prevents dead corners in filling and bonding, ensures uniform bonding of the frame adhesive body, improves bonding quality, avoids poor appearance of electronic devices, and improves production quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A frame adhesive cutting and bonding device includes a base with a tray inserted into it. The base is equipped with a cutting mechanism for cutting out the frame adhesive body and a material transfer mechanism for adsorbing the cut frame adhesive body and bonding it into the tray. The base is also equipped with a filling mechanism for filling the tray with water-based adhesive. The material transfer mechanism is further equipped with a smoothing component. After the water-based adhesive is filled, the material transfer mechanism starts working. While the material transfer mechanism moves the tray with the frame adhesive body, the smoothing component continuously flattens and presses the surface of the water-based adhesive.

[0007] Furthermore, the cutting mechanism includes a cutting frame, a cutting electric cylinder, a cutting air cylinder, and a cutting blade. The cutting frame is mounted on a base and is a gantry frame. The cutting electric cylinder is horizontally positioned at the top center of the cutting frame. The cutting air cylinder is longitudinally connected to the output end of the cutting electric cylinder. The output end of the cutting air cylinder is connected to the cutting blade. The cutting electric cylinder has three cutting stations. The material transfer mechanism can pick up workpieces at at least two cutting stations.

[0008] Furthermore, the material transfer mechanism includes a material transfer frame, a material transfer module, a fine-tuning electric cylinder, a vacuum generator, and a suction cup. The material transfer frame is mounted on a base, the material transfer module is horizontally mounted on the material transfer frame, the fine-tuning electric cylinder is connected to the output end of the material transfer module, and the stroke of the material transfer module is directly above the tray and the cutting station. The vacuum generator is mounted on the mounting end of the fine-tuning electric cylinder, and the output end of the fine-tuning electric cylinder is fixedly connected to the suction cup. The suction cup is connected to the vacuum generator to utilize the generated vacuum to adsorb the adhesive body. The stroke of the fine-tuning electric cylinder is equal to the distance between the suction cup and the surface of the water-based adhesive.

[0009] Furthermore, the material transfer module is an electric cylinder, and a sliding groove is provided on the output end of the electric cylinder. The sliding groove extends along the stroke direction of the electric cylinder, and two lifting rings are slidably connected in the sliding groove. The lifting rings are fitted into the sliding groove, and the top of the lifting rings is fixedly connected to the material transfer frame. The length of the sliding groove corresponds to the stroke length of the electric cylinder.

[0010] Furthermore, the smoothing component includes a smoothing motor, a support rod, and a smoothing body. The smoothing motor is a servo motor, located at the bottom of the output end of the transfer module. The output end of the smoothing motor is vertically fixed to the support rod. The smoothing body is hinged to the outer end of the support rod. The length of the support rod is greater than the distance between the smoothing motor and the bottom surface of the tray.

[0011] Furthermore, the surface of the smoothing body is coated with a polytetrafluoroethylene coating.

[0012] Furthermore, the filling mechanism includes a filling motor, a filling rod, and a glue sprayer. The filling motor is mounted on the base, and its output end is vertically and fixedly connected to the filling rod. The outer end of the filling rod is fixedly connected to the glue sprayer. When the filling motor rotates to its position, the glue sprayer is directly facing the opening of the tray.

[0013] The beneficial effects of this invention are:

[0014] To improve structural reliability, ensure processing quality, prevent dead corners in filling and bonding, ensure uniform bonding of the frame adhesive body, improve bonding quality, avoid poor appearance of electronic devices, and improve production quality. Attached Figure Description

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] like Figure 1 As shown, a frame adhesive cutting and bonding device includes a base 1, a tray 2 inserted into the base 1, a cutting mechanism 3 for cutting out the frame adhesive body 01 on the base 1, a material transfer mechanism 4 for adsorbing the cut frame adhesive body 01 and bonding it into the tray 2, a filling mechanism 5 for filling the tray 2 with water-based adhesive on the base 1, and a smoothing component 6 on the material transfer mechanism 4. After the water-based adhesive is filled, the material transfer mechanism 4 starts to work. While the material transfer mechanism 4 moves the tray 2 with the frame adhesive body 01, the smoothing component 6 continuously flattens and presses the surface of the water-based adhesive.

[0020] In this embodiment, the cutting mechanism 3 includes a cutting frame 31, a cutting electric cylinder 32, a cutting air cylinder 33, and a cutting blade 34. The cutting frame 31 is mounted on the base 1 and is a gantry frame. The cutting electric cylinder 32 is horizontally mounted at the top center of the cutting frame 31. The cutting air cylinder 33 is longitudinally connected to the output end of the cutting electric cylinder 32. The output end of the cutting air cylinder 33 is connected to the cutting blade 34. The cutting electric cylinder 32 has three cutting stations. The material transfer mechanism 4 can adsorb workpieces at at least two cutting stations.

[0021] In this embodiment, the material transfer mechanism 4 includes a material transfer frame 41, a material transfer module 42, a fine-tuning electric cylinder 43, a vacuum generator 44, and a suction cup 45. The material transfer frame 41 is mounted on the base 1, the material transfer module 42 is horizontally mounted on the material transfer frame 41, the fine-tuning electric cylinder 43 is connected to the output end of the material transfer module 42, and the stroke of the material transfer module 42 is directly above the tray 2 and the cutting station. The vacuum generator 44 is mounted on the mounting end of the fine-tuning electric cylinder 43, and the output end of the fine-tuning electric cylinder 43 is fixedly connected to the suction cup 45. The suction cup 45 is connected to the vacuum generator 44 so as to use the generated vacuum to adsorb the frame adhesive body 01. The stroke of the fine-tuning electric cylinder 43 is equal to the distance between the suction cup 45 and the surface of the water adhesive.

[0022] In this embodiment, the material transfer module 42 is an electric cylinder. A groove 7 is provided on the output end of the electric cylinder, extending along the stroke direction of the electric cylinder. Two lifting rings 8 are slidably connected within the groove 7, fitting together and passing through it. The top ends of the lifting rings 8 are fixedly connected to the material transfer frame 41. The length of the groove 7 corresponds to the stroke length of the electric cylinder. The groove 7 and lifting rings 8 facilitate support of the material transfer module 42, preventing the center of gravity of the material transfer module 42 from shifting to one side and ensuring structural stability.

[0023] In this embodiment, the smoothing component 6 includes a smoothing motor 61, a support rod 62, and a smoothing body 63. The smoothing motor 61 is a servo motor and is located at the bottom of the output end of the material transfer module 42. The output end of the smoothing motor 61 is vertically fixed to the support rod 62. The smoothing body 63 is hinged to the outer end of the support rod 62. The length of the support rod 62 is greater than the distance between the smoothing motor 61 and the bottom surface of the tray 2.

[0024] In this embodiment, the surface of the smoothing body 63 is coated with a polytetrafluoroethylene coating.

[0025] In this embodiment, the filling mechanism 5 includes a filling motor 51, a filling rod 52, and a glue sprayer 53. The filling motor 51 is mounted on the base 1. The output end of the filling motor 51 is vertically and fixedly connected to the filling rod 52. The outer end of the filling rod 52 is fixedly connected to the glue sprayer 53. When the filling motor 51 rotates to the correct position, the glue sprayer 53 is facing the opening of the tray 2.

[0026] Working principle:

[0027] like Figure 1 As shown, the material to be cut is first placed on the base 1, positioning it inside the cutting frame 31. Then, the cutting cylinder 33 is moved horizontally to one of the cutting stations by the cutting electric cylinder 32. The extended cutting cylinder 33 drives the cutting blade 34 to cut out the frame adhesive body 01. The cutting stations correspond to the attached... Figure 1Specifically, at locations a, b, and c, the material transfer mechanism 4 can adsorb workpieces from at least two cutting stations. This allows the workpiece to stop at one cutting station, where the cutting cylinder 33 is positioned, and the frame body 01 is cut. Then, the cutting cylinder 33 retracts, and the material transfer module 42 adsorbs and removes the corresponding frame body 01 from the cutting station, ensuring efficient processing of the frame body and effectively utilizing the cutting stations. Subsequently, the cutting cylinder 33 is retracted and moved to the remaining cutting stations by the cutting electric cylinder 32. During this process, the material transfer mechanism 4 can adsorb and remove the workpieces from the corresponding cutting stations. The filling motor 51 drives the filling rod 52 to rotate. Since the glue sprayer 53 is positioned directly opposite the opening of the tray 2 when the filling motor 51 reaches its designated position, the glue sprayer 53 fills the tray 2 with water-based glue. Then, the transfer module 42 drives the vacuum generator 44 to move towards the cut frame adhesive body 01. The fine-tuning cylinder 43 extends, driving the vacuum generator 44 to create a vacuum that adsorbs the frame adhesive body 01. Simultaneously, the smoothing motor 61 is activated, driving the support rod 62 to rotate, which in turn drives the smoothing body 63 to rotate, stabilizing the smoothing body 63 at a specific angle, facilitating full... To meet the pressing requirements of water-based adhesives at different liquid levels, the smoothing body 63 is coated with a polytetrafluoroethylene (PTFE) layer. Furthermore, the smoothing body 63 is hinged to the outer end of the support rod 62, allowing the smoothing body 63 to press the liquid surface smoothly and evenly. The PTFE coating has strong non-stick properties, preventing the water-based adhesive from adhering and ensuring accurate liquid filling without affecting material filling. Then, the transfer module 42 moves the adsorbed frame adhesive body 01. When the frame adhesive body 01 is directly aligned with the liquid surface, the extension fine-tuning electric cylinder 43 extends. Since the stroke of the fine-tuning electric cylinder 43 is equal to that of the suction cup 45... The distance between the water-based adhesive surfaces ensures accurate and effective bonding of the frame adhesive body 01. Before bonding, the smoothing motor 61 drives the smoothing body 63 to rotate. The smoothing body 63 is higher than the top of the tray 2, preventing collisions between the smoothing body 63 and the tray 2. Since the tray 2 is plugged into the chassis, it can be pulled out after bonding. This facilitates material removal, ensures accurate positioning, improves structural reliability, guarantees processing quality, prevents dead corners in the filling and bonding process, ensures uniform bonding of the frame adhesive body 01, improves bonding quality, avoids defects in the appearance of electronic devices, and improves production quality.
