Description

Technical Field

[0001] This utility model relates to the field of FPC bonding technology, and in particular to an FPC bonding device. Background Technology

[0002] Currently, some electronic products use FPC components, which include FPC, copper plates, and coils. In the traditional FPC component production process, the assembly of FPC, copper plates, and coils is usually completed step by step on different specialized devices. The first step is to attach the FPC to the copper plate with high precision. This step is the foundation of the entire assembly process. Its alignment accuracy directly determines the quality of subsequent coil mounting and soldering, and ultimately affects the electrical performance and long-term reliability of the product.

[0003] Existing FPC and copper plate bonding processes typically employ purely mechanical positioning methods, such as relying on the edges of fixtures for rough positioning. However, this method has inherent technical drawbacks: First, due to the small size and thickness of some FPCs, and their inherent flexibility and deformability, they are prone to shifting during gripping and placement, resulting in a deviation between their actual bonding position with the copper plate and their theoretical position. Second, the copper plate also exhibits positional tolerances during processing and loading. Purely mechanical positioning cannot dynamically compensate for these two cumulative errors, making it difficult to guarantee the alignment accuracy between the FPC and the copper plate. This reduces the quality of subsequent product production, affecting product consistency and reliability, failing to meet user needs, and limiting its applicability.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide an FPC bonding device. This device utilizes first to third detection devices to identify the copper plate, FPC, and the gripped FPC to obtain position information. In conjunction with an adjustment device, it compensates for gripping deviations before bonding the FPC to the copper plate. This improves the bonding efficiency and quality between the FPC and the copper plate, meets user needs, and has a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The second detection device is located between the conveying device and the FPC feeding device. The second detection device is used to detect the status information of the FPC after it is gripped. The third detection device is located above the FPC feeding device to detect and obtain the position information of the FPC in the FPC feeding device.

[0009] The gripping and bonding assembly is located beside the conveying device. It is used to grip the FPC from the FPC loading device, move it to the second detection device for detection, and then transfer it back to the conveying device to bond the FPC with the copper plate on the fixture. The gripping and bonding assembly includes a gripping head, a mounting base, a first driving device, and a first displacement device. The gripping head is adjustablely mounted on the mounting base via an adjustment device. The first driving device is connected to the gripping head to control its gripping of the FPC.

[0011] In use, the first detection device detects the copper plate on the fixture and feeds back the information. The gripping head grabs the FPC from the FPC feeding device and moves it above the second detection device. The second detection device detects the FPC and feeds back the information. The rotating device controls the FPC at the gripping head to rotate according to the information feedback from the first and second detection devices, thereby adjusting the position of the FPC and then attaching the FPC to the copper plate of the fixture.

[0012] As a preferred embodiment, the workbench is provided with a mounting frame, and the gripping and bonding component, the first detection device, and the third detection device are all mounted on the mounting frame. The gripping and bonding component is located between the first detection device and the third detection device.

[0013] As a preferred embodiment, the first detection device, the second detection device, and the third detection device are all CCD detection devices.

[0014] As a preferred embodiment, a locking component for locking the position of the fixture is also provided. The locking component is located on the side of the conveying device away from the FPC feeding device and below the first detection device. The locking component includes a locking part and a second driving device. The second driving device is driven and connected to the locking part to control the locking part to move toward the fixture of the conveying device and make contact with the fixture. The conveying device is provided with a clearance hole corresponding to the locking part. One end of the locking part passes through the clearance hole and contacts the fixture.

[0015] As a preferred embodiment, the locking assembly is provided with a sensing unit for sensing whether the fixture is in place.

[0016] As a preferred embodiment, the sensing unit is an infrared sensing unit.

When the third driving device controls the pushing part to push the substandard FPC, copper plate, and fixture to the defective product discharge port and into the defective product placement area through the feeding plate based on the information feedback from the first detection device, the defective product placement area is provided with a defective product placement area.

[0018] As a preferred embodiment, the defective product discharge port is provided with an opening component for opening or closing the defective product discharge port. The opening component includes a closing member and a fourth driving device for driving the closing member to move up and down.

[0029] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0030] An FPC bonding device includes a worktable 10 and a fixture 11 disposed on the worktable 10, a conveying device 12, a gripping bonding component 13, an FPC feeding device 14, a first detection device 15, a second detection device 16, and a third detection device 17.

[0031] The conveying device 12 is used to convey the fixture 11 on which the copper plate is mounted. The first detection device 15 is located above the conveying device 12 to obtain the position information of the copper plate and to detect whether the bonding position of the FPC and the copper plate meets the standard. The second detection device 16 is located between the conveying device 12 and the FPC feeding device 14 and below the gripping and bonding assembly 13. The second detection device 16 is used to detect the status information of the FPC after it is gripped. The third detection device 17 is located above the FPC feeding device 14 to detect and obtain the position information of the FPC in the FPC feeding device.

[0032] The gripping and bonding assembly 13 is disposed on the side of the conveying device 12. The gripping and bonding assembly 12 is used to grip the FPC from the FPC feeding device 14, move it to the second detection device 16 for detection, and then move it back to the conveying device 12 so that the FPC can be bonded to the copper plate on the fixture. The gripping and bonding assembly 13 includes a gripping head 131, a mounting base 132, a first driving device (not shown in the figure), and a first displacement device 133. The gripping head 131 is adjustablely disposed on the mounting base 132 through the adjusting device 182. The first driving device is driven and connected to the gripping head 131 to control the gripping head to grip the FPC. The gripping head 131 is a suction head.

The first displacement device 133 is driven and connected to the mounting base 132 to control the gripping head 131 to move back and forth to the conveying device 12, the second detection device 16, and the FPC feeding device 14.

[0033] Specifically, the workbench 10 is provided with a mounting frame 18, and the gripping and bonding assembly 13, the first detection device 15, and the third detection device 17 are all disposed on the mounting frame 18. The gripping and bonding assembly 13 is located between the first detection device 15 and the third detection device 17. The first detection device 15 and the third detection device 17 are both connected to a second displacement device 181 to control the displacement of the first detection device and the third detection device on the mounting frame. Preferably, the adjustment device 182 is a rotating device, which is driven and connected to the gripping head 131 to control the horizontal rotation of the gripping head to adjust the position of the FPC. Furthermore, the first detection device 15, the second detection device 16, and the third detection device 17 are all CCD detection devices.

[0034] In operation, the first detection device detects the copper plate on the fixture and provides feedback. The gripping head picks up the FPC from the FPC feeding device and moves it above the second detection device. The second detection device detects the FPC and provides feedback. The rotating device controls the FPC at the gripping head to rotate based on the feedback from the first and second detection devices, thereby adjusting the bonding position of the FPC before bonding it to the copper plate on the fixture. Thus, through the design of each component, the first to third detection devices identify the copper plate, FPC, and the gripped FPC to obtain position information. The adjustment device compensates for gripping deviations before bonding the FPC to the copper plate. The entire bonding process is fast, accurate, and automatic, improving the bonding efficiency and quality of the FPC and copper plate, ensuring the stable and consistent quality of each product, reducing rework caused by incorrect positioning, meeting user needs, and having a wide range of applications.

The second driving device 192 is driven and connected to the locking part 191 to control the locking part to move towards the fixture of the conveying device and make contact with the fixture. The conveying device 12 is provided with a clearance hole 121 corresponding to the locking part. One end of the locking part 191 passes through the clearance hole 121 and contacts the fixture 11. Specifically, the locking assembly... Component 1+ is equipped with a sensing unit (not shown in the figure) for sensing whether the fixture is in place. The sensing unit is an infrared sensing unit. Thus, the locking component is set to lock the position of the positioning fixture on the conveying device, thereby ensuring the bonding effect of FPC and copper plate and ensuring the consistency of product quality. At the same time, the sensing unit is set to automatically sense the position of the fixture and lock the fixture with the locking component to prevent the fixture position from deviating. After bonding is completed, the locking component unlocks the fixture. The operation is simple and convenient, which helps to improve the bonding accuracy and bonding quality between FPC and copper plate, and has good usability.

[0036] Furthermore, the workbench 10 is provided with a defective product placement area (not shown in the figure) and a pushing device 20. The defective product placement area is located on the right side of the conveying device 12, away from the FPC feeding device 14. The conveying device 12 is provided with a defective product discharge port 122. The defective product placement area is connected to the defective product discharge port 122 of the conveying device 12 through a feeding plate 123. The pushing device 20 is located on the other side of the conveying device 12 and is set corresponding to the defective product discharge port. The pushing device 20 includes a pushing part and a third driving device (not shown in the figure) for controlling the displacement of the pushing part. When the third driving device controls the pushing part to push the substandard FPC, copper plate and fixture to the defective product discharge port and into the defective product placement area through the feeding plate according to the information feedback from the first detection device, the defective products are removed from the conveying device and enter the defective product placement area, which is beneficial for the subsequent rework of the defective products and avoids the defective products from entering the subsequent processing steps.

[0037] Furthermore, an opening component 21 for opening or closing the defective product discharge port 122 is provided at the defective product discharge port 122. The opening component 21 includes a closing member 211 and a fourth driving device 212 for driving the closing member to move up and down. The closing member 211 is located at the upper end of the defective product discharge port 122. In this way, the opening component is provided to avoid the fixture from coming into contact with the defective product discharge port during the transfer of the fixture on the conveying device, which would affect the transfer and use of the fixture on the conveying device and ensure the stability of the fixture on the conveying device.

[0038] In this embodiment, two of each of the gripping and bonding component, FPC feeding device, first detection device, second detection device, third detection device, and locking component are provided and arranged correspondingly along the conveying direction of the conveying device. It should be noted that the user can configure multiple gripping and bonding components, FPC feeding devices, first detection devices, second detection devices, third detection devices, and locking components according to the number of FPCs to be bonded to the copper plate. These multiple gripping and bonding components, FPC feeding devices, first detection devices, second detection devices, third detection devices, and locking components are arranged correspondingly along the conveying direction of the conveying device to realize the bonding operation of multiple FPCs at different positions on the copper plate.

[0039] The key design feature of this invention lies in its design of various components. It utilizes first to third detection devices to identify the copper plate, FPC, and the gripped FPC to obtain position information.
