Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automatic welding device for flexible wires. Background Technology

[0002] FPC, also known as flexible conductor, is a printed circuit board made of flexible insulating substrate. After bending, flexible conductors may have uncertain left-right and front-back position offsets, as well as inaccurate bending angles. When matched with the product's vacuum forming board, there will be dimensional deviations, resulting in poor product welding quality. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of the FPC wire having an uncertain position after bending, which leads to low welding quality in the prior art, and to provide an automatic welding device for flexible wires that can automatically detect the position of FPC wires after bending and thus perform precise welding.

[0004] Therefore, this utility model provides an automatic welding device for flexible wires, including a body and a support for preventing the flexible wires from moving. A welding mechanism capable of axial movement is provided above the support. The welding mechanism includes a welding head for welding the flexible wires and a data lookup device for determining the position of the flexible wires. The data lookup device is communicatively connected to the welding head. When the data lookup device detects the welding position of the flexible wires, the welding head can move to the welding position to weld the flexible wires.

[0005] Furthermore, the welding mechanism also includes a positioning block, on which the welding head and the data finder are both located and can move synchronously with the positioning block, and a driving mechanism for driving the positioning block to move axially is provided at the positioning block.

[0006] Furthermore: the driving component includes a first linear motor for driving the positioning block to move longitudinally and a longitudinal moving track for assisting the positioning block to move. A moving block is provided above the longitudinal moving track, and a transverse moving track adapted to it is provided above the moving block. A second linear motor for driving it to move along the transverse moving track is provided on the moving block.

[0007] Furthermore, a servo motor is provided between the positioning block and the welding head to assist the vertical movement of the welding head.

[0008] Furthermore, the welding mechanism also includes a detector for detecting welding quality, which is connected to the positioning block.

[0009] Furthermore, the welding mechanism also includes an irradiator, which can irradiate the area above the bearing, with the irradiation point located at the origin.

[0010] Furthermore: a pressure plate is provided above the bearing, and the pressure plate is connected to a driving device, which can drive the pressure plate to press the flexible wire from top to bottom.

[0011] Furthermore, the side of the pressure plate opposite to the flexible conductor is also provided with a pressure block that can press down on the flexible conductor and a gripper for holding the flexible conductor.

[0012] The technical solution of this utility model has the following advantages:

[0013] 1. This utility model provides an automatic welding device for flexible conductors. The flexible conductors need to be welded to components on a PCB board. Before welding, the data finder first locates the position of the flexible conductor, then takes a picture to identify its coordinate position, and then converts it into data and sends it to the control system. The control system feeds back the information to the welding head, and the welding head starts to move to the target position for welding. In this way, the position detection and welding of the flexible conductor can be completed automatically, avoiding the welding failure caused by uncertain left-right and front-back position offsets and inaccurate bending angles after the flexible conductor is bent, which exists in the prior art. In this embodiment, the technology of the control system transmitting information is the prior art, and the controller can also be purchased according to actual needs.

[0014] 2. This utility model provides an automatic welding device for flexible wires. A data finder is located in front of the welding head. During welding, the data finder and the welding head move with the positioning block. After the data finder finds the position of the flexible wire, it continues to move forward. The welding head on the side moves to the flexible wire that the data finder just found and performs welding. At the same time, the data finder searches for the position of the next flexible wire. This process is repeated. Through the setting of the driving device, the positioning block can be moved, thereby driving the data finder to collect position data of each flexible wire, which facilitates the welding head to perform precise welding of the flexible wire.

[0027] Example

[0028] This embodiment provides an automatic welding device for flexible conductors, including a body 1 and a support 2 for preventing the flexible conductors from moving. A welding mechanism capable of axial movement is provided above the support 2. The welding mechanism includes a welding head 3 for welding the flexible conductors and a data lookup device 31 for determining the position of the flexible conductors. The data lookup device 31 is communicatively connected to the welding head 3. When the data lookup device 31 detects the welding position of the flexible conductor, the welding head 3 can move to the welding position to weld the flexible conductor.

[0029] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, the flexible conductor needs to be soldered to components on the PCB board. Compared with the prior art, in this embodiment, before soldering, the data lookup device 31 first locates the position of the flexible conductor, then takes a picture to identify its coordinate position, and then converts it into data and sends it to the control system. The control system feeds back the information to the soldering head 3, and the soldering head 3 starts to move to the target position for soldering. In this way, the position detection and soldering of the flexible conductor can be completed automatically, avoiding the situation in the prior art where the flexible conductor has uncertain left and right, front and back position offsets and inaccurate bending angles after bending, which leads to soldering failure. The technology of the control system transmitting information in this embodiment is the prior art, and the controller can also be purchased according to actual needs.

[0030] Based on the above embodiments: the welding mechanism further includes a positioning block 4, the welding head 3 and the data finder 31 are both disposed on the positioning block 4 and can move synchronously with the positioning block 4, and a driving mechanism 5 for driving the positioning block 4 to move axially is provided at the positioning block 4.

[0031] The specific improvements mentioned above are as follows: Figure 2 As shown, the data finder 31 is positioned in front of the welding head 3. During welding, the data finder 31 and the welding head 3 move along with the positioning block 4. After the data finder 31 finds the position of the flexible wire, it continues to move forward. The welding head 3 on the side moves to the flexible wire that the data finder 31 just found and welds it. At the same time, the data finder 31 searches for the position of the next flexible wire. This process repeats. Through the setting of the drive device 7, the positioning block 4 can be moved, thereby driving the data finder 31 to collect position data of each flexible wire, which facilitates the welding head 3 to perform precise welding on the flexible wire.

[0032] Based on the above embodiments: the driving component includes a first linear motor 51 for driving the positioning block 4 to move longitudinally and a longitudinal moving track 52 for assisting the positioning block 4 to move. A moving block 53 is provided above the longitudinal moving track 52. A transverse moving track 54 adapted to the moving block 53 is provided above the moving block 53. A second linear motor 55 is provided on the moving block 53 for driving it to move along the transverse moving track 54.

[0033] The specific improvements mentioned above are as follows: Figure 2 and Figure 5 As shown, the first linear motor 51 and the longitudinal moving track 52 drive the positioning block 4 to move longitudinally. There is a connecting plate above the longitudinal moving track 52, and there is a rolling chain on the longitudinal moving track 52. The rolling chain can roll along the setting direction of the connecting plate. A moving block 53 is fixed above the connecting plate. The moving block 53 can move along the setting direction of the transverse moving track 54. The second linear motor 55 can drive the moving block 53 to move, so as to realize the automated production of the product.

[0034] Based on the above embodiments: a servo motor 56 is provided between the positioning block 4 and the welding head 3 to assist the vertical movement of the welding head 3.

[0035] The specific improvements mentioned above are as follows: Figure 2 As shown, the servo motor 56 can assist the welding head 3 in vertical movement.

[0036] Based on the above embodiments: the welding mechanism further includes a detector 6 for detecting welding quality, the detector 6 being connected to the positioning block 4.

[0037] The specific improvements mentioned above are as follows: Figure 2 As shown, a detector 6 is also installed on the welding mechanism to detect the welding quality of the welding head 3. When the welding head 3 finishes welding a wire and moves to the next position to weld the next wire, there will be a detection camera on the detector 6. The detection camera will move above the welded flexible wire to take pictures and detect it. The data finder 31 and the detector 6 are connected by a horizontal plate. The data finder 31 and the detector 6 are respectively fixed at both ends of the horizontal plate, which is fixed on the positioning block 4.

[0038] Based on the above embodiments: the welding mechanism also includes an irradiator 61, which can irradiate the area above the bearing 2, with the irradiation point located at the origin.

[0039] The specific improvements mentioned above are as follows: Figure 5As shown, the position illuminated by the irradiator 61 is used as the origin coordinates for the data lookup device 31 to refer to. After the origin coordinates are determined by the irradiator 61, the data lookup device 31 will calculate the coordinate data of the flexible conductor's position by referring to the origin coordinates determined by the irradiator 61, and then feed it back to the control system. The control system will then feed the information back to the welding head 3, and the welding head 3 will start to move to the target position for welding.

[0040] Based on the above embodiments: a pressure plate 21 is provided above the support 2, and the pressure plate 21 is connected to a driving device 7, which can drive the pressure plate 21 to press the flexible wire from top to bottom.

[0041] The specific improvements mentioned above are as follows: Figure 3 and Figure 4 As shown, a pressure plate 21 is provided above the support 2. Before welding the flexible wires, the PCB board is conveyed from the side to the support 2. Then, the pressure plate 21 moves downward by the drive device 7 to press the PCB board, thereby preventing the PCB board from moving and ultimately causing the flexible wire welding to fail.

[0042] Based on the above embodiments: the side of the pressure plate 21 opposite to the flexible conductor is also provided with a pressure block 8 that can press down on the flexible conductor and a gripper 81 for holding the flexible conductor.

[0043] The specific improvements mentioned above are as follows: Figure 4 As shown, in order to further fix the position of the flexible conductor, the pressure plate 21 is provided with a gripper 81 and a pressure block 8. The gripper 81 will first bend the flexible conductor, and after bending, the pressure block 8 will press down the bent position, thus waiting for the welding head 3 to perform welding.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
