Technical Field

[0001] This utility model belongs to the field of metal frame adhesive film application technology, specifically relating to a metal frame adhesive film application and pressing device. Background Technology

[0002] Electronic products typically feature metal frames to protect the screen and internal components, reducing the risk of damage. Before installation, the metal frame often undergoes plating, etching, and other processing. To ensure optimal processing results, the metal frame must be cleaned and a protective film applied before processing to prevent secondary contamination of the surface to be processed. Currently, the protective film is typically applied manually to the metal frame. However, manual application suffers from several problems: 1. Inconsistent placement and poor quality due to varying skill levels; 2. The risk of mixing or using incorrect materials; 3. Slow efficiency, unable to keep pace with production lines, resulting in low production capacity. Improvements are urgently needed. Utility Model Content

The lifting plates 124 pass through the gap between two adjacent support frames 114 or between the support frame 114 and the adjacent adjustment frame 115 to lift the material tray on the feeding seat 111 upward. Furthermore, the first lifting assembly 123 is a common structure in the field of lifting mechanisms. It can be made by using a motor with transmission components and a lead screw and nut pair. Its specific structure will not be described in detail here.

[0022] The second lifting mechanism 14 is used to move the empty material tray downwards to the unloading mechanism 13. Its structure is the same as that of the first lifting mechanism 12, and will not be described further here. The unloading mechanism 13 is used to transport the empty material tray outwards.

An elastic buffer layer is provided at the lower end of the lower material receiving plate 242.

The picking head 246 passes through the corresponding picking hole 247 to adsorb the corresponding metal frame 6 part; after the metal frame 6 is moved into place by the picking seat 22, the limiting cylinder 245 drives the limiting plate 244 to move upward, which in turn moves the magnetic picking head 246 upward into the picking hole 247, disengaging from the metal frame 6, thus realizing the clamping and transfer of the metal frame 6; furthermore, the picking lifting module 25 is a common structure in the mechanical field that can drive components to move up and down, which will not be described in detail here.

[0025] Reference Figures 7 to 8As shown, the attitude correction and positioning device 3 includes a positioning platform 31, a correction mechanism 32, a first detection mechanism, a second detection mechanism, and a third detection mechanism. The correction mechanism 32 is disposed on the positioning platform 31 to correct the position of the metal frame 6 that has been moved to the positioning platform 31. The first detection mechanism and the second detection mechanism are disposed at intervals on the positioning platform 31 along the length direction of the wide side plate 61.

[0026] The calibration mechanism 32 includes a first calibration plate 321, a second calibration plate 322, a first calibration movable plate 323, a second calibration movable plate 324, a first calibration cylinder 325, and a second calibration cylinder 326. The first calibration plate 321 and the second calibration plate 322 are arranged at right angles on the positioning platform 31. The first calibration movable plate 323 is mounted on the positioning platform 31 and moves back and forth relative to the right angle formed by the first calibration plate 321 and the second calibration plate 322. The second calibration movable plate 324 is mounted on the positioning platform 31 and moves back and forth relative to the first calibration plate 321. The first calibration cylinder 325 is mounted on the positioning platform 31 and connects to... The first correction moving plate 323 is driven to move; the second correction cylinder 326 is set on the positioning table 31 and is connected to drive the second correction moving plate 324 to move; when the metal frame 6 is corrected, the first correction cylinder 325 cooperates with the second correction cylinder 326 to make the first correction moving plate 323 and the second correction moving plate 324 move closer to the metal frame 6 respectively, and position the metal frame 6 between the first correction fixed plate 321, the second correction fixed plate 322, the first correction moving plate 323 and the second correction moving plate 324; specifically, the first correction moving plate 323 is L-shaped, so that the two sides of the first correction moving plate 323 contact the opposite connecting plate 63 and the narrow side plate 62 respectively.

[0027] The first detection mechanism, set on the positioning table 31, detects the calibrated metal frame 6 to confirm its type. It includes two first detection sensors 33 positioned opposite each other on the positioning table 31. The first detection sensor 33, located on the same side as the narrow side plate 62, detects whether the narrow side plate 62 has a chamfered corner, thus confirming the type of metal frame 6. By adjusting the positions of the two first detection sensors 33 on the positioning table 31, when both sensors provide signal feedback, the metal frame 6 is the metal frame 6 of the first embodiment. When one sensor provides signal feedback but the other does not, the metal frame 6 is determined to be the metal frame 6 of the second embodiment. When neither sensor provides signal feedback, an alarm is triggered. Specifically, the first detection mechanism is designed to detect when the metal frame 6 of the first embodiment is coated with film, causing disruption to the production line due to the inclusion of a metal frame 6 of the second embodiment.

[0028] The second detection mechanism detects the wide side plate 61 and narrow side plate 62 of the metal frame 6 to confirm the placement orientation of the metal frame 6. This includes two second detection sensors 34 arranged opposite each other on the positioning platform 31. The signals fed back by the two second detection sensors 34 confirm the position of the wide side plate 61 and narrow side plate 62, thereby confirming the placement orientation of the metal frame 6. By adjusting the position of the two second detection sensors 34 on the positioning platform 31, the second detection sensor 34 opposite the narrow side plate 62 will not provide a signal feedback, while the second detection sensor 34 opposite the wide side plate 61 will provide a signal feedback, thereby determining the placement orientation of the metal frame 6. When both second detection sensors 34 provide a signal feedback, an alarm is triggered.

[0029] The third detection mechanism, set on the positioning platform 31, is used to detect whether the metal frame 6 is properly aligned. It includes two third detection sensors 35 arranged opposite each other on the positioning platform 31. By adjusting the position of the two third detection sensors 35 on the positioning platform 31, when the metal frame 6 is properly aligned, both third detection sensors 35 will provide signal feedback. When the two third detection sensors 35 do not provide signal feedback or only one provides signal feedback, an alarm will be triggered.

[0030] Specifically, the positioning stage 31 is provided with mounting holes 311 for mounting the first detection sensor 33, the second detection sensor 34, or the third detection sensor 35. The first detection sensor 33, the second detection sensor 34, or the third detection sensor 35 are mounted in the mounting holes 311 via mounting blocks 312. The mounting blocks 312 are provided with strip-shaped fixing holes 313, which facilitates adjusting the mounting position of the mounting blocks 312 on the positioning stage 31 according to the detection requirements of the first detection sensor 33, the second detection sensor 34, or the third detection sensor 35, thereby adjusting the mounting position of the first detection sensor 33, the second detection sensor 34, or the third detection sensor 35. Furthermore, the first detection sensor 33, the second detection sensor 34, or the third detection sensor 35 are proximity sensors.

The transfer clamping mechanism 43 is mounted on the transfer plate 42 and clamps the metal frame 6 on the positioning table 31, transferring it to the adhesive film bonding and pressing device 5. The rotating mechanism 44 and the transfer linear module 45... The transfer clamping mechanism 43 is connected to confirm whether the rotating mechanism 44 drives the transfer clamping mechanism 43 to rotate 180° to adjust the adhesive film application direction of the metal frame 6 based on the signals fed back by the first and second detection mechanisms. The transfer linear module 45 is set on the transfer frame 41 to drive the transfer plate 42 to move. It is a common structure in the mechanical field and will not be described in detail here. When the metal frame 6 is in the correct adhesive film application direction on the positioning table 31, the wide side plate 61 is arranged close to the adhesive film application and pressing device 5, and the narrow side plate 62 is arranged close to the material picking device 2.

The rotating mechanism 44 is disposed between the clamping plate 431 and the magnetic adsorption assembly 433. Based on the signals fed back by the first detection mechanism and the second detection mechanism, it confirms whether the rotating mechanism 44 drives the magnetic adsorption assembly 433 to rotate 180° to adjust the adhesive film attachment direction of the metal frame 6. Specifically, the clamping lifting module 432 is a common structure in the mechanical field that can drive components to move up and down, which will not be described in further detail here.

Multiple guide posts 4339 are mounted on the lower connecting plate 4332. The lower end of each guide post 4339 is connected to the lower connecting plate 4332, and the upper end extends upward through the relative guide sleeve 4338.
