Technical Field

[0001] This utility model relates to the field of bonding devices, specifically a bonding device for DOME sheets used in flexible FPCs. Background Technology

[0002] Bonding equipment is used to precisely bond two or more materials or components together. It is widely used in fields such as electronics manufacturing, optical device manufacturing, and automotive industry. When workers bond DOME sheets onto flexible FPCs, they need to use bonding equipment for precise processing.

[0003] However, current bonding devices still have some shortcomings. For example, the automatic material handling function of existing bonding devices is poor, which means that the bonding device needs to spend a long time picking up and feeding DOME sheets, thus interfering with the processing efficiency of the bonding device and resulting in certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a bonding device for DOME sheets for flexible FPC. Summary of the Invention

[0005] The purpose of this invention is to provide a bonding device for DOME sheets used in flexible FPCs, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bonding device for DOME sheets used in flexible FPC, comprising a worktable and a support bracket. A first fixing plate is fixedly installed at the bottom of the worktable, and a first servo motor is installed at the bottom left side of the worktable. The output shaft of the first servo motor is connected to a first drive screw via a coupling. A support component is slidably connected to the top of the worktable, and a DOME sheet placement frame is fixedly installed on the top of the worktable. The support bracket is fixedly installed on the top of the worktable, and second fixing plates are symmetrically installed at the front and back of the top of the support bracket. A second servo motor is installed on the top of the support bracket, and a second drive screw is installed on the output shaft of the second servo motor via a coupling. A material picking component is slidably connected to the inner surface of the top of the support bracket. An electric heating box is installed on the top right side of the worktable.

[0007] Furthermore, the bearing assembly includes a bearing frame, a cross-shaped slider, a first connecting mechanism, a T-shaped slider, and a locking mechanism. The bottom of the bearing frame is fixedly mounted with a cross-shaped slider, and the bottom of the cross-shaped slider is fixedly connected with the first connecting mechanism. The interior of the first connecting mechanism is movably connected to the side of the first drive screw. Meanwhile, T-shaped sliders are symmetrically mounted on the bottom of the bearing frame, and the locking mechanism is movably mounted on the inner surface of the top of the bearing frame.

[0008] Furthermore, the bottom of the support frame is fixedly connected to the top of the T-shaped slide bar, and the support frame forms a sliding structure with the worktable through the T-shaped slide bar.

[0009] Furthermore, the locking mechanism includes a locking plate, a T-shaped slider, and a handle, with T-shaped sliders symmetrically installed on the left and right sides of the locking plate, and a handle fixedly installed on the top of the locking plate.

[0010] Furthermore, the outer side of the locking plate is fixedly connected to the inner side of the T-shaped slider, and the locking plate forms a sliding structure with the support frame through the T-shaped slider.

[0011] Furthermore, the material handling assembly includes a support plate, a guide slider, a second connecting mechanism, an electric telescopic rod, a hollow connecting plate, an air pump, and vacuum suction cups. The top of the support plate is fixedly mounted with a guide slider, and the top of the guide slider is fixedly connected with the second connecting mechanism. The interior of the second connecting mechanism is movably connected to the side of the second drive screw. Meanwhile, the bottom of the support plate is symmetrically mounted with electric telescopic rods, and the bottom of the electric telescopic rods is mounted with a hollow connecting plate. The top of the hollow connecting plate is fixedly mounted with an air pump, and the bottom of the hollow connecting plate is equipped with vacuum suction cups arranged in an array at equal intervals.

[0012] Furthermore, the fixed end of the electric telescopic rod is fixedly connected to the bottom of the bearing plate, and the extended end of the electric telescopic rod is fixedly connected to the top of the hollow connecting plate.

[0013] This invention provides a bonding device for DOME sheets used in flexible FPCs, which has the following advantages:

[0014] 1. This utility model utilizes an air pump to automatically generate suction force in the vacuum suction cup during operation. This allows the vacuum suction cup to automatically pick up and grip the topmost DOME sheet in the DOME sheet placement frame. Then, through the cooperation of the second servo motor and the second drive screw, the material picking component automatically delivers the picked-up DOME sheet to the top of the flexible FPC in the carrier component. Finally, the operation of the electric telescopic rod completes the automatic bonding operation between the flexible FPC and the DOME sheet. This avoids the situation where the bonding device spends a long time picking up and feeding the DOME sheet, which would interfere with the processing efficiency of the bonding device.

[0015] 2. This utility model, through the setting of a first drive screw, enables the first servo motor to drive the bearing component to move left and right along the top of the worktable during operation. When the bearing component moves the flexible FPC to directly below the bearing support, it can automatically complete the bonding work of the DOME sheet. When the bearing component moves into the interior of the electric heating box, its internal temperature can automatically complete the bonding connection between the DOME sheet and the flexible FPC, thereby completing the overall processing work. This greatly reduces the workload of the workers and improves the processing efficiency of the device. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 3As shown, a bonding device for DOME sheets used in flexible FPC includes a worktable 1 and a support bracket 7. A DOME sheet placement frame 6 is fixedly installed on the top of the worktable 1. The support bracket 7 is fixedly installed on the top of the worktable 1, and second fixing plates 8 are symmetrically installed on the front and back of the top of the support bracket 7.

Meanwhile, a material picking assembly 11 is slidably connected to the inner surface of the top of the support bracket 7. The material picking assembly 11 includes a support plate 111, a guide slider 112, a second connecting mechanism 113, an electric telescopic rod 114, a hollow connecting plate 115, an air pump 116, and a vacuum suction cup 117. A guide slider 112 is fixedly installed on the top of the support plate 111, and a second connecting mechanism 113 is fixedly connected to the top of the guide slider 112. The interior of the second connecting mechanism 113 is movably connected to the side of the second drive screw 10. Meanwhile, electric telescopic rods 114 are symmetrically installed at the bottom of the support plate 111. The fixed end of the electric telescopic rod 114 is fixedly connected to the bottom of the support plate 111, and the extended end of the electric telescopic rod 114 is fixedly connected to the top of the hollow connecting plate 115. The hollow connecting plate 115 is installed at the bottom of the electric telescopic rod 114, and an air pump 116 is fixedly installed on the top of the hollow connecting plate 115. Vacuum suction cups 117 are installed in an array at equal intervals at the bottom of the hollow connecting plate 115.

[0022] like Figure 1 and Figure 2As shown, a first fixed plate 2 is fixedly installed on the bottom of the worktable 1, and a first servo motor 3 is installed on the left bottom of the worktable 1. The output shaft of the first servo motor 3 is connected to a first drive screw 4 via a coupling. A bearing assembly 5 is slidably connected to the top of the worktable 1. The bearing assembly 5 includes a bearing frame 51, a cross-shaped slider 52, a first connecting mechanism 53, a T-shaped slide bar 54, and a locking mechanism 55. The cross-shaped slider 52 is fixedly installed on the bottom of the bearing frame 51, and the first connecting mechanism 53 is fixedly connected to the bottom of the cross-shaped slider 52. The interior of the first connecting mechanism 53 is movably connected to the side of the first drive screw 4. Meanwhile, T-shaped slide bars 54 are symmetrically installed on the bottom of the bearing frame 51. The bottom of the bearing frame 51 is fixedly connected to the top of the T-shaped slide bars 54, and the bearing frame 51 is connected to the worktable via the T-shaped slide bars 54. A sliding structure is formed. By configuring the support frame 51 and the worktable 1 as a sliding structure, the support frame 51 can move more smoothly and stably when moving left and right along the top of the worktable 1. A locking mechanism 55 is movably installed on the top inner surface of the support frame 51. The locking mechanism 55 includes a locking plate 551, a T-shaped slider 552 and a handle 553. The T-shaped sliders 552 are symmetrically installed on the left and right sides of the locking plate 551. The outer side of the locking plate 551 is fixedly connected to the inner side of the T-shaped slider 552. The locking plate 551 and the support frame 51 form a sliding structure through the T-shaped slider 552. By configuring the locking plate 551 and the support frame 51 as a sliding structure, the locking mechanism 55 can be quickly disassembled and assembled by the operator. The handle 553 is fixedly installed on the top of the locking plate 551. An electric heating box 12 is installed on the top right side of the worktable 1.

[0023] In summary, the bonding device for DOME sheets in this flexible FPC firstly... Figures 1 to 3As shown in the diagram, the operator places the DOME sheets to be bonded and assembled into the DOME sheet placement frame 6. Next, the operator installs the flexible FPC into the inner surface of the support frame 51. Then, the operator grasps the handle 553 and slides the T-shaped slider 552 to install the locking plate 551 into the top inner surface of the support frame 51, thereby limiting the end position of the flexible FPC. The operator then activates the first servo motor 3 via the controller. When the first servo motor 3 starts running, it drives the first drive screw 4 to rotate inside the first fixed plate 2. At this time, the first connecting mechanism 53... The sliding of the cross-shaped slider 52 and the T-shaped slider 54 causes the support frame 51 to move to the right along the top of the workbench 1. When the support frame 51 moves directly below the support bracket 7, the first servo motor 3 stops running. Then, the operator turns on the second servo motor 9 through the controller. When the second servo motor 9 starts running, it drives the second drive screw 10 to rotate inside the second fixed plate 8. At this time, through the connection of the second connecting mechanism 113 and the sliding of the guide slider 112, the support plate 111 drives the hollow connecting plate 115 to move back and forth along the top inner surface of the support bracket 7. When the hollow connecting plate 115 moves to DO... When the DOME sheet is directly above the DOME sheet placement frame 6, the second servo motor 9 stops operating. Then, the operator opens the electric telescopic rod 114 via the controller. When the electric telescopic rod 114 starts operating, it drives the hollow connecting plate 115 downwards. When the bottom of the vacuum suction cup 117 is in contact with the topmost DOME sheet in the DOME sheet placement frame 6, the electric telescopic rod 114 is closed and the air pump 116 is turned on. When the air pump 116 starts operating, the vacuum suction cup 117 automatically generates suction to grip the DOME sheets in the DOME sheet placement frame 6. Then, the operator opens the electric telescopic rod 114 and the second servo motor 9 via the controller, causing the material handling assembly to... The DOME sheet held by component 11 is moved to the top of the support frame 51. Then, the operator opens the electric telescopic rod 114 through the controller, so that the hollow connecting plate 115 moves the DOME sheet to the upper surface of the flexible FPC. The slight downward pressure applied by the electric telescopic rod 114 completes the bonding work between the two. Then, the operator turns off the air pump 116 and opens the electric telescopic rod 114, so that the material picking component 11 separates from the DOME sheet. Then, the operator turns on the first servo motor 3 again, so that the support component 5 moves the bonded flexible FPC into the electric heating box 12 for subsequent processing.
