Description

Technical Field

[0001] This utility model relates to the field of stretching device technology, and in particular to a processing device for bidirectional stretching flexible electronic devices. Background Technology

[0002] Flexible electronics is an emerging electronic technology that fabricates electronic devices made of organic and inorganic materials on flexible substrates. Flexible electronic devices need to be stretched during processing, but traditional processing equipment for stretching flexible electronic devices is prone to damage when stretching them, thus limiting its practicality.

[0003] Current technology CN117565377A discloses a processing apparatus for biaxially stretched flexible electronic devices, including a stand, rubber traction rollers and a limiting mechanism, a drive mechanism, and a dust extraction and preheating assembly. The rubber traction rollers are four sets arranged horizontally and rotatably connected to the surface of the stand. These rollers are used to stretch the flexible electronic device. The limiting mechanism is located on the stand and is used to stretch the flexible electronic device. This biaxially stretched flexible electronic device processing apparatus can perform biaxial stretching processing on the flexible electronic device using round-roller-type rubber traction rollers without causing shear damage.

[0004] However, using the above method, the flexible electronic device is stretched in both directions by pulling the two ends of the flexible electronic device through two round rubber traction rollers on the left and right sides. However, since the distance between the two rubber traction rollers on the same side is fixed and cannot be adjusted according to the thickness of the flexible electronic device, it can only stretch flexible electronic devices of a single thickness, which limits the applicability of the device.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] This utility model provides a processing device for biaxially stretched flexible electronic devices, including a stand 101, two stretching components 102, a linear drive element 118, and a limiting roller 119. The stretching component 102 includes a drive component 103 and two stretching components 104. The stretching component 104 includes a mounting frame 105, a rubber traction roller 106, a rotary drive element 107, a connecting arm 111, a rotating shaft 112, and a rubber guide roller 113. The drive component 103 includes a guide rail 108, two sliders 109, and a biaxial threaded screw 110. The connecting arm 111 includes a connecting rod 114, an outer column 115, an inner column 116, and a screw 117. The aforementioned solution can stretch flexible electronic devices of different thicknesses, thus improving the applicability.

[0023] In this specific embodiment, two tensioning components 102 are located on both sides of the upright frame 101. Each tensioning component 102 includes a driving component 103 and two tensioning components 104. The driving component 103 is disposed on the side of the upright frame 101. The two tensioning components 104 are located on both sides of the driving component 103. Each tensioning component 104 includes a mounting frame 105, a rubber traction roller 106, and a rotary driving element 107. The mounting frame 105 is disposed on the side of the driving component 103. The rubber traction roller 106 is rotatably connected to the mounting frame 105 and is located on the side of the mounting frame 105. The rotary driving element 107 is disposed on the side of the rubber traction roller 106. In use, the two ends of the flexible electronic device are respectively fed between the two rubber traction rollers 106. The two rotary drive elements 107 on the same side drive the two rubber traction rollers 106 to rotate towards each other. The two ends of the flexible electronic device are pulled by the two rubber traction rollers 106 on both sides of the stand 101, thereby performing bidirectional stretching. When it is necessary to stretch flexible electronic devices of different thicknesses, the drive component 103 is controlled to drive the two mounting frames 105 and the two rubber traction rollers 106 to move towards or away from each other according to the thickness of the flexible electronic device. This allows adjustment of the distance between the two rubber traction rollers 106 to accommodate the thickness of the flexible electronic device, thus enabling traction and stretching of flexible electronic devices of different thicknesses and improving the applicability. The rotary drive element 107 adopts existing technology, such as a motor.

[0024] The guide rail 108 is fixedly connected to the support frame 101 and is located on the side of the support frame 101; the two sliders 109 are slidably connected to the guide rail 108 and fixedly connected to the two mounting brackets 105 respectively, and are located inside the guide rail 108 respectively; the bidirectional threaded screw 110 is rotatably connected to the guide rail 108 and threadedly connected to the two sliders 109 respectively, and is located inside the guide rail 108. The guide rail 108 provides guidance for the slider 109. The two ends of the bidirectional threaded screw 110 have threads in opposite directions. The two sliders 109 are located at opposite ends of the thread direction of the bidirectional threaded screw 110. Depending on the thickness of the flexible electronic device, the operator rotates the bidirectional threaded screw 110 clockwise or counterclockwise. The rotation of the bidirectional threaded screw 110 causes the two sliders 109 to slide along the guide rail 108 in a direction that moves closer to or further away from each other. The two sliders 109 drive the two mounting brackets 105 and the rubber traction rollers 106 to move, thereby adjusting the distance between the two rubber traction rollers 106 to accommodate the thickness of the flexible electronic device.

[0025] Secondly, the connecting arm 111 is fixedly connected to the mounting frame 105 and located on the side of the mounting frame 105; the rotating shaft 112 is rotatably connected to the connecting arm 111 and located at the end of the connecting arm 111 away from the mounting frame 105; the rubber guide roller 113 is fixedly connected to the rotating shaft 112 and located at the end of the rotating shaft 112 away from the connecting arm 111. The connecting arm 111 is used to support the rotating shaft 112 and the rubber guide roller 113, feeding both ends of the flexible electronic device between the two rubber guide rollers 113 and the two rubber traction rollers 106 respectively. The two rubber guide rollers 113 can provide a limit when the flexible electronic device is stretched, preventing the flexible electronic device from shifting during the stretching process.

[0026] Meanwhile, the connecting rod 114 is fixedly connected to the mounting bracket 105 and is located on the side of the mounting bracket 105; the outer column 115 is fixedly connected to the connecting rod 114 and is located on the side of the connecting rod 114; the inner column 116 is slidably connected to the outer column 115 and rotatably connected to the rotating shaft 112, and is located inside the outer column 115; the screw 117 is rotatably connected to the outer column 115 and threadedly connected to the inner column 116, and is located on the side of the outer column 115. The connecting rod 114 is used to connect the mounting bracket 105 and the outer column 115. The inner column 116 is used to support the rotating shaft 112 to rotate. By rotating the screw 117, the inner column 116 moves longitudinally along the outer column 115. The inner column 116 drives the rotating shaft 112 and the rubber guide roller 113 to move longitudinally, so that the height position of the rubber guide roller 113 can be adjusted according to the length of the flexible electronic device, so as to limit the flexible electronic device at a suitable position.

[0027] In addition, the linear drive element 118 is disposed on the side of the upright 101; the limiting roller 119 is disposed on the side of the linear drive element 118. The linear drive element 118 can drive the limiting roller 119 to move longitudinally, and the limiting roller 119 can be used to limit the flexible electronic device and prevent the flexible electronic device from shifting when stretched; the linear drive element 118 adopts existing technology, for example, a cylinder can be used.

[0028] When using this invention, the two ends of the flexible electronic device are respectively fed between the two rubber guide rollers 113 and the two rubber traction rollers 106. The linear drive element 118 is controlled to drive the limiting roller 119 to move longitudinally, and the limiting roller 119 is used to limit the flexible electronic device. The two rotary drive elements 107 on the same side are controlled to drive the two rubber traction rollers 106 to rotate in opposite directions. The two ends of the flexible electronic device are pulled by the two rubber traction rollers 106 on both sides of the stand 101, thereby performing bidirectional stretching. The two rubber guide rollers 113 can provide a limit when stretching the flexible electronic device, preventing the flexible electronic device from shifting during the stretching process. When it is necessary to stretch flexible electronic devices of different thicknesses, the operator rotates the bidirectional threaded screw 110 forward or backward according to the thickness of the flexible electronic device. The rotation of the bidirectional threaded screw 110 causes the two sliders 109 to slide along the guide rail 108 in a direction that moves closer or further away from each other. The two sliders 109 drive the two mounting brackets 105 and the rubber traction rollers 106 to move, thereby adjusting the distance between the two rubber traction rollers 106 to adapt to the thickness of the flexible electronic device. This allows for the stretching of flexible electronic devices of different thicknesses, thus improving the applicability.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
