Description

Technical Field

[0001] This utility model relates to the field of cable laying and bonding technology, and in particular to a testing device for the bonding of flexible flat cable auxiliary materials. Background Technology

[0002] With the rapid development of modern electronic technology, electronic products such as smartphones, tablets, and wearable devices are constantly evolving towards miniaturization and high integration. Flexible flat cables play a crucial role in these devices, enabling signal transmission and power supply within a limited space.

[0003] Traditional auxiliary material pasting relies on manual visual inspection, which has problems such as low efficiency, high missed detection rate and inability to quantify detection. Existing equipment mostly uses a single sensor for detection, which is difficult to take into account complex defects such as positional misalignment, air bubbles, and uneven thickness. Utility Model Content

[0004] To address the problems of low efficiency, high missed detection rate, and inability to quantify detection associated with traditional auxiliary material bonding that relies on manual visual inspection, and the fact that existing equipment often uses a single sensor for detection, making it difficult to take into account complex defects such as positional misalignment, air bubbles, and uneven thickness, this utility model provides a flexible flat cable auxiliary material bonding detection device.

[0005] This utility model is achieved using the following technical solution: a flexible flat cable auxiliary material bonding and testing device, comprising a workbench, a fixed box for storing adhesive is provided in the middle of the workbench, a roller is rotatably connected inside the fixed box, a first servo motor coaxial with the roller is fixedly connected to the outer side of the fixed box horizontally parallel to the roller, a support platform is fixedly connected to the top of the workbench, a slider is slidably connected to the inner side of the top of the support platform, an electric telescopic rod is fixedly connected to the bottom of the slider, a suction cup for adsorbing the flexible flat cable and the flexible flat cable auxiliary material is provided at the bottom of the electric telescopic rod, an L-shaped plate is also fixedly connected to the bottom of the slider, a camera is installed in the middle of the bottom of the L-shaped plate, and a pair of laser thickness gauges and multiple infrared thermal imagers are also installed at the bottom of the L-shaped plate.

[0006] Through the above technical solution, the electric telescopic rod drives the suction cup to move up and down and sequentially suck up the flexible flat cable and the flexible flat cable auxiliary material and move them to the detection table at the top of the workbench. When the flexible flat cable auxiliary material is moved, the first servo motor will be turned on to rotate, so that the surface of the roller inside the fixed box is covered with glue. This ensures that the flexible flat cable auxiliary material is evenly covered with glue when it passes the top of the roller and is finally pasted together with the flexible flat cable.

[0007] Then, the camera, laser thickness gauge and infrared thermal imager on the bottom of the L-shaped plate integrate optical positioning, laser thickness measurement and air pressure sensing to achieve three-in-one detection of position, thickness and fit.

[0008] As a further improvement to the above solution, a connecting block is fixedly connected to the bottom end of the electric telescopic rod, the suction cup is fixedly connected to the bottom end of the connecting block, and a vacuum generator is fixedly connected to the top end of the connecting block.

[0009] As a further improvement to the above solution, the connecting block has an internal cavity, and a connecting tube is symmetrically fixed between the connecting block and the suction cup, and the connecting tube is connected to the internal cavity.

[0010] The above technical solution uses the opening and closing of the vacuum generator to control the suction cup to pick up and place flexible flat cables and flexible flat cable accessories.

[0011] As a further improvement to the above scheme, a pair of laser thickness gauges are symmetrically arranged on the outside of the camera, and multiple infrared thermal imagers are located at the four corners of the bottom of the L-shaped plate.

[0012] As a further improvement to the above solution, a sliding groove is provided on the inner side of the top of the support platform, and a reciprocating screw is rotatably connected inside the sliding groove. A second servo motor coaxial with the reciprocating screw is fixed to the outer side of the vertical parallel side of the support platform. The slider nut pair is connected to the outer side of the reciprocating screw and slides inside the sliding groove. A feed port and a discharge port are provided on both vertical parallel sides of the support platform.

[0013] As a further improvement to the above solution, a controller is fixedly connected to the outer side of the worktable in a horizontal parallel direction. The first servo motor, the second servo motor, the camera, the laser thickness gauge, and the infrared thermal imager are all electrically connected to the controller.

[0014] Through the above technical solution, the second servo motor drives the reciprocating screw inside the slide to rotate, thereby causing the slider to move laterally inside the slide.

[0015] The feed port on one side of the support platform is matched with the feeding component, and the discharge port on the other side of the support platform is matched with the feeding component; the first servo motor, the second servo motor, the camera, the laser thickness gauge and the infrared thermal imager are all electrically connected to the controller to realize the complete automation of the equipment and greatly reduce production costs.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the process of bonding flexible flat cables and their auxiliary materials, this invention uses suction cups to adsorb the auxiliary materials. When the auxiliary materials pass the top of the roller, their bonding surface is covered with glue, thus bonding the flexible flat cables and avoiding the low-quality issues that can occur with manual bonding. The camera, laser thickness gauge, and infrared thermal imager on the bottom of the L-shaped plate integrate optical positioning, laser thickness measurement, and air pressure sensing to achieve a three-in-one detection of position, thickness, and fit. This solves the problem that existing equipment with single-sensor detection cannot adequately address complex defects such as positional deviation, air bubbles, and uneven thickness.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-4A flexible flat cable accessory bonding inspection device includes a workbench 1. A fixed box 2 for storing adhesive is set in the middle of the workbench 1. A roller 3 is rotatably connected inside the fixed box 2. A first servo motor 4, coaxial with the roller 3, is fixed to the outer side of the fixed box 2. A support platform 5 is fixed to the top of the workbench 1. A slider 6 is slidably connected to the inner side of the top of the support platform 5. An electric telescopic rod 7 is fixed to the bottom of the slider 6. A suction cup 8 for adsorbing flexible flat cables and flexible flat cable accessories is set at the bottom of the electric telescopic rod 7. An L-shaped plate 9 is also fixed to the bottom of the slider 6. A camera 22 is installed in the middle of the bottom of the L-shaped plate 9. A pair of laser thickness gauges 10 and multiple infrared thermal imagers 11 are also installed at the bottom of the L-shaped plate 9. The pair of laser thickness gauges 10 are symmetrically arranged outside the camera 22, and the multiple infrared thermal imagers 11 are located at the four corners of the bottom of the L-shaped plate 9.

[0026] The electric telescopic rod 7 drives the suction cup 8 to move up and down and sequentially pick up the flexible flat cable and the flexible flat cable auxiliary material and move them to the detection table at the top of the workbench 1. When the flexible flat cable auxiliary material is moved, the first servo motor 4 will be turned on simultaneously to rotate, so that the surface of the roller 3 inside the fixed box 2 is covered with glue. When the flexible flat cable auxiliary material passes the top of the roller 3, it is evenly covered with glue and finally glued to the flexible flat cable.

[0027] Then, a camera 22, a laser thickness gauge 10, and an infrared thermal imager 11 are placed on the bottom of the L-shaped plate 9. A pair of laser thickness gauges 10 are symmetrically arranged on the outside of the camera 22, and multiple infrared thermal imagers 11 are located at the four corners of the bottom of the L-shaped plate 9. The system integrates optical positioning, laser thickness measurement, and air pressure sensing to achieve a three-in-one detection of position, thickness, and fit.

[0028] Combination Figure 4 A connecting block 12 is fixedly connected to the bottom end of the electric telescopic rod 7, a suction cup 8 is fixedly connected to the bottom end of the connecting block 12, a vacuum generator 13 is fixedly connected to the top end of the connecting block 12, a cavity 14 is provided inside the connecting block 12, and a connecting pipe 15 is symmetrically fixed between the connecting block 12 and the suction cup 8, and the connecting pipe 15 is connected to the internal cavity 14.

[0029] By turning on the vacuum generator 13, the air between the suction cup 8 and the material first enters the connecting pipe 15 between the suction cup 8 and the connecting block 12 from the suction cup 8, and then enters the vacuum generator 13 from the cavity 14 of the connecting block 12 and is expelled from the outside, making the inside of the suction cup 8 hollow, thus achieving the suction of the material.

[0030] Combination Figure 2The support platform 5 has a sliding groove 16 on the inner side of its top end. A reciprocating screw 17 is rotatably connected inside the sliding groove 16. A second servo motor 18, coaxial with the reciprocating screw 17, is fixedly connected to the outer side of the vertical parallel side of the support platform 5. The slider 6 and nut are connected to the outer side of the reciprocating screw 17 and slide inside the sliding groove 16. The support platform 5 has a feed port 19 and a discharge port 20 on both vertical parallel sides. A controller 21 is fixedly connected to the outer side of the horizontal parallel side of the worktable 1. The first servo motor 4, the second servo motor 18, the camera 22, the laser thickness gauge 10, and the infrared thermal imager 11 are all electrically connected to the controller 21.

[0031] The second servo motor 18 drives the reciprocating screw 17 inside the slide groove 16 to rotate, thereby causing the slider 6, which is connected to the outside of the reciprocating screw 17, to move laterally and slide inside the slide groove 16.

[0032] The implementation principle of the flexible flat cable auxiliary material adhesion detection device in this application embodiment is as follows:

[0033] First, the feeding mechanism will sequentially feed the flexible flat cable and the flexible flat cable auxiliary material into the feed port 19 in sequence. At this time, the electric telescopic rod 7 and the second servo motor 18 will be activated by the controller 21.

[0034] The electric telescopic rod 7 moves up and down, causing the suction cup 8 to adhere to the top of the flexible flat cable. Then, the vacuum generator 13 is turned on to expel the air inside the suction cup 8 and create a vacuum state, which adsorbs the flexible flat cable. At this time, the controller 21 turns on the second servo motor 18 to drive the reciprocating screw 17 inside the slide groove 16 to rotate, so that the slider 6 connected to the outside of the reciprocating screw 17 by the nut pair moves laterally to the left and slides inside the slide groove 16 until the flexible flat cable is located on the top left side of the worktable 1.

[0035] Then the suction cup 8 returns to the initial position and adsorbs the flexible flat cable auxiliary material. At this time, the controller 21 simultaneously turns on the first servo motor 4 and the second servo motor 18, so that the surface of the roller 3 inside the fixing box 2 is covered with glue, so that the flexible flat cable auxiliary material is evenly covered with glue when it passes the top of the roller 3, and finally it is pasted together with the flexible flat cable.

[0036] Finally, the controller 21 enables the camera 22, laser thickness gauge 10, and infrared thermal imager 11 on the L-shaped plate 9 to perform a three-in-one detection of position, thickness, and fit.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
