Description

Technical Field

[0001] This invention relates to the field of circuit board contact welding technology, and in particular to a flexible circuit control panel processing equipment and production method. Background Technology

[0002] In the manufacturing process of flexible circuit control panels, soldering is the core process of electronic assembly, which aims to form a reliable electrical and mechanical connection between the flexible circuit board and the PCB or components.

[0003] In the fabrication of flexible circuit control panels, soldering is a core assembly process, primarily used to ensure stable and reliable electrical conduction and mechanical fixation between the flexible circuit board's ribbon cable contacts and the PCB panel pads. Currently, traditional soldering fixtures and simple soldering equipment on the market rely entirely on manual alignment and placement of the flexible circuit boards by eye. Manual placement errors are difficult to eliminate, and the flexible circuit boards are prone to lateral shifting. Furthermore, the flexible board itself is thin and lightweight, lacking rigid support. During soldering, the ribbon cable contacts are easily slipped and misaligned due to the combined effects of the soldering iron's downward pressure and the high-temperature airflow disturbance, making precise alignment with the PCB pads impossible. This results in batches of soldering defects such as cold solder joints, missing solder joints, and short circuits caused by solder bridges. This not only leads to a large amount of rework and repair work but also directly causes the circuit boards to be scrapped, significantly reducing the finished product yield and hindering stable mass production. Summary of the Invention

[0004] Therefore, it is necessary to provide a flexible circuit control panel processing equipment and production method to address the problems of low efficiency and poor accuracy in centering flexible circuit boards using current welding equipment.

[0005] The above objectives are achieved through the following technical solutions: A flexible circuit control panel processing device, comprising: An operating table is provided with a fixed block, and a rotating block is rotatably connected to one side of the fixed block. A first receiving groove is provided on the upper surface of the fixed block for accommodating a PCB panel, and a second receiving groove is provided on the upper surface of the rotating block for accommodating a flexible circuit board. The positioning block has two blocks, which are slidably disposed on the fixed block. When the rotating block moves upward around the rotation center, it pushes the two positioning blocks closer to each other to center the flexible circuit board. A connection component for connecting a flexible circuit board and a PCB panel; A power assembly is used to drive the rotating block to rotate about a rotation center; The rotating block is provided with two push blocks, and each push block is ball-connected to a connecting rod. One end of the connecting rod is ball-connected to the push block, and the other end of the connecting rod is ball-connected to the positioning block. The bottom of the positioning block is provided with a protruding ridge. The fixed block is provided with a sliding groove. The extension direction of the sliding groove is parallel to the rotation axis of the fixed block and the rotating block. The protruding ridge slides within the sliding groove.

[0006] Furthermore, the positioning block is provided with a cylindrical limiting block, the axis of which is parallel to the rotation axis of the rotating block, and an elastic disc is provided on the end face of the two cylindrical limiting blocks that are close to each other. The elastic disc is used to abut against both sides of the bent part of the flexible circuit board.

[0007] Furthermore, the connection assembly includes a soldering iron and a conveyor. The soldering iron is vertically slidably disposed above the connection position between the flexible circuit board and the PCB panel, and the conveyor is used to horizontally convey the solder wire to the connection position between the flexible circuit board and the PCB panel.

[0008] Furthermore, the fixing block is provided with a welding wire straightening component, which is used to straighten the welding wire.

[0009] Furthermore, the welding wire straightening assembly includes a first clamping plate and a second clamping plate, which are located on a fixed block. When the rotating block moves upward around the rotation center, the second clamping plate moves toward the first clamping plate to clamp and straighten the welding wire. The fixed block has two parallel guide rails, the extension direction of which is perpendicular to the extension direction of the groove. A sliding block is slidably disposed on the guide rail, and a guide groove is provided at the bottom of the sliding block. The guide groove is slidably disposed on the guide rail. A push rod is hinged to the sliding block, one end of which is hinged to the sliding block, and the other end of which is hinged to the push block.

[0010] Furthermore, the first clamping plate and the second clamping plate have stepped surfaces on their adjacent end faces. The upper half of the first clamping plate is thicker than the lower half, and the connection between the upper half and the lower half of the first clamping plate is a smooth arc surface. The upper part of the second clamping plate is thinner than the lower half, and the connection between the upper half and the lower half of the second clamping plate is also a smooth arc surface.

[0011] Furthermore, a first retaining strip and a second retaining strip are provided on both sides of the second receiving groove. The first retaining strip and the second retaining strip are used to restrict the movement of the flexible circuit board in a direction perpendicular to the rotation axis of the rotating block.

[0012] Furthermore, the power assembly includes a telescopic cylinder and a transmission rod. The telescopic cylinder is horizontally fixed on the operating table. The telescopic end of the telescopic cylinder is hinged to one end of the transmission rod, and the other end of the transmission rod is hinged to the end of the rotating block away from the rotation center.

[0013] This invention also provides a method for manufacturing a flexible circuit control panel, comprising the following steps: Step S1: First, install the PCB panel in the first receiving slot, and then install the flexible circuit board in the second receiving slot; Step S2: The power component drives the rotating block to rotate upward around the rotation center, and the two positioning blocks move closer to each other to center the flexible circuit board in the second receiving groove. Step S3: The connecting component moves downward to connect the flexible circuit board and the PCB panel; Step S4: After the connection is completed, the power component drives the rotating block to rotate in the opposite direction, and the flexible circuit board detaches from the second receiving groove.

[0014] The beneficial effects of this invention are: This invention features a rotating block that can rotate around a rotation center and a sliding positioning block. When the rotating block rotates around the rotation center, a curved portion is formed on the flexible circuit board. The two positioning blocks can approach each other to push the curved portion of the flexible circuit board, and the curved portion is not easily deformed, thereby positioning the flexible circuit board in the center. At the same time, the curved portion of the flexible circuit board allows the ribbon cable contacts of the flexible circuit board to abut against the connection contacts of the PCB panel without manual pressing, thus improving the welding quality.

[0015] This invention features a cylindrical limiting block on a positioning block, with an elastic disc mounted on the cylindrical limiting block. When the rotating block rotates upward around its rotation center, the two sides of the bent portion of the flexible circuit board are pushed by the elastic disc. The elastic disc can elastically extend and retract along the axial direction of the cylindrical limiting block, thereby using its own elasticity to buffer and offset the overshooting force during the positioning and centering process. At the same time, the elastic disc makes soft contact with the flexible circuit board, preventing scratches to the insulating protective film on the surface of the flexible circuit board and ensuring the integrity of the workpiece's appearance.

[0016] This invention improves welding quality by setting a welding wire straightening component on a fixed block. The welding wire straightening component is used to straighten the welding wire, avoiding displacement, skewing, or local bending and misalignment caused by its own deformation and airflow disturbance during the feeding process.

[0022] The following reference Figures 1-10 This invention describes a flexible circuit control panel processing device.

[0023] A flexible circuit control panel processing device, suitable for soldering flexible circuit boards 600, includes an operating table 100, a fixing block 110 disposed on the operating table 100, a rotating block 200 rotatably connected to one side of the fixing block 110, a first receiving groove 120 formed on the upper surface of the fixing block 110 for receiving a PCB panel 500, the PCB panel 500 being limited by the first receiving groove 120 when inside the first receiving groove 120, and a second receiving groove 210 formed on the rotating block 200 for receiving... The flexible circuit board 600 is positioned within the second receiving groove 210 and can be limited by the second receiving groove 210. During processing, the operator first places the PCB panel 500 into the first receiving groove 120, and then places the flexible circuit board 600 into the second receiving groove 210. The ribbon cable contact 610 of the flexible circuit board 600 will be located above the PCB panel 500. Specifically, the PCB panel 500 is provided with connecting contacts, and the ribbon cable contact 610 is located on the connecting contacts when the flexible circuit board 600 is in the second receiving groove 210.

[0024] A connecting component is provided on the operating table 100. The connecting component is specifically located above the ribbon cable contact 610 of the flexible circuit board 600. The connecting component is used to connect the connecting contact of the PCB panel 500 with the ribbon cable contact 610 of the flexible circuit board 600. The connecting component includes a soldering iron 300 and a conveyor 320. The soldering iron 300 is vertically slidably positioned above the connection position of the flexible circuit board 600 and the PCB panel 500. The soldering iron 300 can move in the vertical direction. The bottom of the soldering iron 300 is rectangular. The conveyor 320 is located on one side of the fixing block 110. The conveyor 320 is used to horizontally convey the solder wire 310 to the connection position of the flexible circuit board 600 and the PCB panel 500. When the soldering iron 300 moves downward, it pushes the solder wire 310 and melts the solder wire 310. The molten solder wire 310 connects the ribbon cable contact 610 of the flexible circuit board 600 with the connecting contact of the PCB panel 500.

[0025] To prevent the flexible circuit board 600 from shifting during the connection process, the fixing block 110 of the present invention is provided with two positioning blocks 130. The two positioning blocks 130 are slidably disposed on the fixing block 110. The two positioning blocks 130 are configured to move closer to each other when the rotating block 200 moves upward around the rotation center, thereby centering the flexible circuit board 600 in the second receiving groove 210.

[0026] It should be noted that, in this embodiment, the connection position between the ribbon cable contact 610 and the flexible circuit board 600 forms a bent portion 620 when the rotating block 200 rotates upward. When the flexible circuit board 600 is located in the second receiving groove 210 and the rotating block 200 rotates upward around the rotation center, the two positioning blocks 130 move closer to each other to push the bent portion 620. At this time, the two positioning blocks 130 push the two sides of the bent portion 620, thereby centering the flexible circuit board 600 in the second receiving groove 210 and preventing the ribbon cable contact 610 on the flexible circuit board 600 from shifting.

[0027] By setting two relatively sliding positioning blocks 130, during the upward flipping of the rotating block 200, the two positioning blocks 130 synchronously approach each other and push against both sides of the curved portion 620 of the flexible circuit board 600. When the curved portion 620 is in a bent state, the curved portion 620 is not easily deformed when the two positioning blocks 130 push against both sides of the curved portion 620, thus making the centering positioning effect of the flexible circuit board 600 better. Automatic centering positioning can be achieved without repeated manual fine-tuning of the placement position of the flexible circuit board 600. This can not only avoid the flexible circuit board 600 from slipping and misaligning due to the pressure of the soldering iron 300 and the disturbance of high temperature airflow during the connection process, but also avoid the ribbon cable contact 610 deviating from the PCB pad, causing connection failure and product scrapping. Furthermore, it can unify the connection alignment benchmark of each workpiece, ensuring that the connection position height of the flexible circuit control panel in the same batch is consistent, which can improve the consistency of product processing.

[0028] It should also be noted that, as the rotating block 200 in this embodiment rotates upward around the rotation center, the ribbon cable contact 610 of the flexible circuit board 600 will bend. The reaction force of the bending can make the ribbon cable contact 610 of the flexible circuit board 600 abut against the PCB panel 500, thereby making the ribbon cable contact 610 and the connecting contact of the PCB panel 500 fit tightly together, reducing the small gap between them, and avoiding defects such as poor soldering, false soldering, and poor solder wetting caused by poor contact between the contact and the pad during connection. At the same time, with the pre-compression force generated by the bending of the ribbon cable contact 610 itself, the flexible circuit board 600 can be further constrained at the moment when the soldering iron 300 is pressed down to melt and solder, further improving the alignment stability of the ribbon cable contact 610 and the connecting contact during the connection process.

[0029] Specifically, to allow the two positioning blocks 130 to approach each other when the rotating block 200 rotates upward, the fixed block 110 in this embodiment is provided with a groove 140. The extension direction of the groove 140 is parallel to the rotation axis of the fixed block 110 and the rotating block 200. Each of the two positioning blocks 130 has a protruding ridge 132 at its bottom. The two positioning blocks 130 are slidably positioned within the groove 140 via the protruding ridge 132. Furthermore, two push blocks 220 are fixedly mounted on the rotating block 200. Each push block 220 has a connecting rod 221 ball-jointed to it. One end of the connecting rod 221 ball-joints the push block 220, and the other end ball-joints the positioning block 130. The connecting rod 221 is in an inclined state, meaning its axis is not perpendicular to the rotation center of the rotating block 200, but rather... Figure 2 As shown, when the rotating block 200 moves upward around the rotation center, the two push blocks 220 on the rotating block 200 push the two positioning blocks 130 through the connecting rod 221. The two positioning blocks 130 approach each other in the slide groove 140, so as to push the flexible circuit board 600 on the curved portion 620 between the flexible circuit board 600 and the ribbon cable contact 610 to center and position the flexible circuit board 600.

[0030] It should be noted that, in this embodiment, the positioning block 130 is provided with a cylindrical limiting block 131. The axis of the cylindrical limiting block 131 is parallel to the rotation axis of the fixed block 110 and the rotating block 200. An elastic disk 133 is provided on the end face of the two cylindrical limiting blocks 131 that are close to each other. The elastic disk 133 can elastically extend and retract along the axial direction of the cylindrical limiting block 131. When the two positioning blocks 130 are close to each other, the elastic disk 133 can abut against the bent portion 62 of the flexible circuit board 600. On both sides, the elastic setting of the elastic disc 133 can prevent the positioning block 130 from being forcibly pushed when it moves, and prevent the rigid cylindrical limiting block 131 from directly and rigidly squeezing the bent part 620 of the flexible circuit board 600. The elastic disc 133 moves synchronously with the positioning block 130, and can offset the over-thrust during the positioning and centering process through its own elastic buffer. At the same time, the elastic disc 133 and the flexible circuit board 600 are in soft contact, which will not scratch the insulating protective film on the surface of the flexible circuit board 600, ensuring the workpiece has an intact appearance.

[0031] In a further embodiment, the fixing block 110 of the present invention is provided with a welding wire 310 straightening component, which is used to straighten the welding wire 310, thereby avoiding the occurrence of displacement, skewing or local bending and misalignment of the welding wire 310 due to its own deformation and airflow disturbance during the feeding process.

[0032] Specifically, the welding wire 310 straightening assembly in this embodiment includes a first clamping plate 150 and a second clamping plate 160. When the rotating block 200 rotates upward around the rotation center, the second clamping plate 160 moves toward the first clamping plate 150 to clamp the welding wire 310, thereby positioning and straightening the welding wire 310. This ensures that the welding wire 310 is located directly above the ribbon cable contact 610 of the flexible circuit board 600, preventing the welding wire 310 from shifting, tilting, or being partially bent or misaligned due to its own deformation or airflow disturbance during the feeding process.

[0033] It should be noted that, in this embodiment, the end faces of the first clamping plate 150 and the second clamping plate 160 that are close to each other are provided with stepped surfaces. That is, the thickness of the upper half of the end face of the first clamping plate 150 close to the end face of the second clamping plate 160 is greater than the thickness of the lower half, and the connection between these two parts is a smooth arc surface. The thickness of the upper half of the end face of the second clamping plate 160 close to the end face of the first clamping plate 150 is less than the thickness of the lower half, and the connection between these two parts is also a smooth arc surface. When the second clamping plate 160 is close to the first clamping plate 150, the smooth arc surfaces of the first clamping plate 150 and the second clamping plate 160 can clamp the welding wire 310 to straighten the welding wire 310. After straightening, the second clamping plate 160 moves away from the first clamping plate 150, so as not to affect the soldering iron 300 pushing the welding wire 310.

[0034] Specifically, in order to enable the second clamping plate 160 to move toward the first clamping plate 150, a sliding block 170 is slidably provided on the fixing block 110 in this embodiment. The sliding direction of the sliding block 170 is perpendicular to the sliding direction of the positioning block 130. A push rod 171 is hinged on the sliding block 170. One end of the push rod 171 is hinged to the sliding block 170, and the other end of the push rod 171 is hinged to the push block 220. When the rotating block 200 moves upward around the rotation center, the push block 220 and the push rod 171 push the second clamping plate 160 toward the first clamping plate 150. In order to enable the first clamping plate 150 and the second clamping plate 160 to rotate, two abutment blocks 190 are provided on the fixing block 110 in this embodiment. One end of the first clamping plate 150 is rotatably connected to one of the abutment blocks 190, and one end of the second clamping plate 160 is rotatably connected to one of the sliding blocks 170. Before the operator or robot places the PCB panel 500 into the first receiving slot 120, the first clamping plate 150 and the second clamping plate 160 move upward around the rotation center to avoid affecting the placement of the PCB panel 500. After the PCB panel 500 and the flexible circuit board 600 are placed, the first clamping plate 150 and the second clamping plate 160 move downward around the rotation center. At this time, the suspended end of the first clamping plate 150 slides in contact with another abutment block 190, which has a supporting function. The suspended end of the second clamping plate 160 slides in contact with another sliding block 170, which also has a supporting function.

[0035] More specifically, in order to make the sliding block 170 slidably connected to the fixed block 110, two guide rails 180 are fixedly provided on the fixed block 110 in this embodiment. The two guide rails 180 are parallel to each other, and the extension direction of the two guide rails 180 is perpendicular to the extension direction of the slide groove 140. The bottom of the sliding block 170 is provided with a guide groove 172. The sliding block 170 is slidably disposed on the guide rail 180 through the guide groove 172 so that it can slide along the extension direction of the guide rail 180.

[0036] In a further embodiment, a first retaining bar 230 and a second retaining bar 240 are provided on both sides of the second receiving groove 210 of the present invention. The first retaining bar 230 and the second retaining bar 240 are located on both sides of the second receiving groove 210. The first retaining bar 230 and the second retaining bar 240 are used to restrict the flexible circuit board 600 from moving in a direction perpendicular to the rotation axis of the rotating block 200. The operator or robot needs to form the flexible circuit board 600 into an arc shape so that the flexible circuit board 600 can pass over the first retaining bar 230 and the second retaining bar 240 and enter the second receiving groove 210. After the flexible circuit board 600 enters the second receiving groove 210, the flexible circuit board 600 returns to a straight state. At this time, the first retaining bar 230 and the second retaining bar 240 will restrict the flexible circuit board 600 from sliding in the second receiving groove 210 in a direction perpendicular to the rotation axis of the rotating block 200.

[0037] In a further embodiment, the power assembly of the present invention includes a telescopic cylinder 400 and a transmission rod 410. The telescopic cylinder 400 is fixedly mounted on the operating table 100. The telescopic end of the telescopic cylinder 400 is hinged to one end of the transmission rod 410, and the other end of the transmission rod 410 is hinged to the end of the rotating block 200 away from the rotation center. Figure 6 As shown, in the initial state, the rotating block 200 and the fixed block 110 are in a flat state, and the telescopic cylinder 400 is in an extended state. When the telescopic end of the telescopic cylinder 400 is shortened, the rotating block 200 is pushed to rotate upward around the hinge position through the transmission rod 410.

[0038] The specific working process of the flexible circuit control panel processing equipment provided by the present invention will be described in conjunction with the above embodiments: In the initial state: When the upper surfaces of the rotating block 200 and the fixed block 110 are aligned, the telescopic cylinder 400 is in an extended state. The operator or robot arm places the PCB panel 500 and the flexible circuit board 600 to be connected into the first receiving groove 120 and the second receiving groove 210 respectively. The PCB panel 500 needs to be placed into the first receiving groove 120 first, and then the flexible circuit board 600 is placed into the second receiving groove 210. The first locking strip 230 and the second locking strip 240 in the second receiving groove 210 restrict the flexible circuit board 600 to move in a direction perpendicular to the rotation axis of the rotating block 200.

[0039] Subsequently, the first clamping plate 150 and the second clamping plate 160 rotate downwards synchronously, thereby pressing the ribbon cable contact 610 of the flexible circuit board 600 onto the PCB panel 500. The welding wire 310 is then fed above the ribbon cable contact 610. After the welding wire 310 is fed, the telescopic end of the telescopic cylinder 400 begins to shorten. The telescopic end of the telescopic cylinder 400 drives the rotating block 200 to rotate upwards around its rotation center via the transmission rod 410. Simultaneously, the push block 220 on the rotating block 200 pushes the connecting rod 221 and the push rod 171. Two connecting rods 221 respectively push two positioning blocks 130 closer to each other within the slide groove 140. At this time, the connection between the flexible circuit board 600 and the ribbon cable contact 610 begins to bend, forming a bent portion 620. The elastic disc 133 on the positioning block 130 gradually pushes the two sides of the bent portion 620, thereby centering the flexible circuit board 600 within the second receiving groove 210. Two push rods 171 push two sliding blocks 170 to move along the extension direction of the guide rail 180. The two sliding blocks 170 push the second receiving groove 210. The clamping plate 160 moves toward the first clamping plate 150 to straighten the welding wire 310. After the welding wire 310 is straightened, the telescopic end of the telescopic cylinder 400 extends a certain distance, causing the rotating block 200 to rotate downward around the rotation center at a certain angle, but not beyond the plane where the upper end face of the fixed block 110 is located. This causes the second clamping plate 160 to move away from the first clamping plate 150, avoiding affecting the soldering iron 300's pushing of the welding wire 310. When the rotating block 200 rotates downward around the rotation center, the two positioning blocks 130 move away from each other to disengage. The bent portion 620 of the flexible circuit board 600, because the flexible circuit board 600 is in a bent state, has a downward force abutting the bottom of the first receiving groove 120 at one end of the flexible circuit board 600. Therefore, when the two positioning blocks 130 move away from each other, they do not affect the already centered flexible circuit board 600. Then the soldering iron 300 moves from top to bottom and pushes the solder wire 310 downward to connect the ribbon cable contact 610 of the flexible circuit board 600 to the PCB panel 500.

[0040] After the connection is completed, the telescopic end of the telescopic cylinder 400 gradually extends, the rotating block 200 rotates downward around the rotation center and passes over the plane where the upper end face of the fixed block 110 is located. At this time, one end of the flexible circuit board 600 is located in the first receiving groove 120 and is clamped by the first clamping plate 150 and the second clamping plate 160. As the rotating block 200 moves downward around the rotation center, the other end of the flexible circuit board 600 will disengage from the second receiving groove 210, making it easy for the operator or robot to take it out.

[0041] After the operator or robotic arm grasps the flexible circuit board 600 that pops out from the second receiving slot 210, the soldering iron 300 moves upward to reset, and the first clamping plate 150 and the second clamping plate 160 rotate upward around their own rotation center to facilitate the removal of the PCB panel 500 and the flexible circuit board 600.

[0042] This invention also provides a method for manufacturing a flexible circuit control panel, which requires the aforementioned flexible circuit control panel manufacturing equipment and includes the following steps: Step S1: First, install the PCB panel 500 in the first receiving groove 120, and then install the flexible circuit board 600 in the second receiving groove 210. Step S2: The power component drives the rotating block 200 to rotate upward around the rotation center, and the two positioning blocks 130 move closer to each other to center the flexible circuit board 600 in the second receiving groove 210. Step S3: The connecting component moves downward to connect the flexible circuit board 600 and the PCB panel 500; Step S4: After the connection is completed, the power component drives the rotating block 200 to rotate in the opposite direction, and the flexible circuit board 600 disengages from the second receiving groove 210.

[0043] When the rotating block 200 rotates in the opposite direction, the second receiving groove 210 on the rotating block 200 will gradually move away from the flexible circuit board 600. Since one end of the flexible circuit board 600 is clamped in the first receiving groove 120, the flexible circuit board 600 will detach from the second receiving groove 210.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
