Description

Technical Field

[0001] This invention relates to the field of circuit board manufacturing technology, and in particular to a rapid positioning structure for circuit board manufacturing. Background Technology

[0002] In the circuit board manufacturing process, it is usually necessary to apply adhesive to the solder lines on the circuit board. Before curing, the adhesive has a certain degree of fluidity. If the circuit board is warped, tilted, or uneven in some areas, the adhesive tends to flow to lower areas and accumulate, resulting in uneven adhesive layer thickness, affecting the adhesive application quality and subsequent processing. Therefore, during the adhesive application process, it is generally necessary to position the circuit board and flatten the left and right sides of the adhesive application area to keep the circuit board flat.

[0003] In existing technologies, positioning and flattening structures for circuit board gluing typically include a base and positioning components mounted on the base. The circuit board is positioned by insertion using the positioning components, and pressure is applied to the upper surface of the circuit board by a clamping mechanism. However, the pressure points of existing clamping mechanisms are often relatively fixed, and the flattening distance on the left and right sides is either not adjustable or inconvenient to adjust. When the circuit board specifications change, such as differences in circuit board size, gluing area position, or positioning insertion position, the flattening positions on the left and right sides are difficult to accurately correspond to the gluing area, resulting in poor flattening effect and potentially affecting the gluing operation due to pressure point deviation. Furthermore, for multiple circuit boards arranged side by side, it is necessary to ensure the synchronicity and consistency of flattening of each circuit board, which is difficult to achieve with existing structures. Therefore, how to provide a rapid positioning structure that can insert and position the circuit board, adjust the flattening positions on the left and right sides of the gluing area according to the circuit board specifications, and ensure synchronicity of flattening is a technical problem that urgently needs to be solved in this field.

[0024] like Figures 1 to 6As shown, the present invention provides a quick positioning structure for circuit board production, including a base 10. A plurality of positioning components 20 are disposed on the base 10. The plurality of positioning components 20 are arranged in a left-right direction. The positioning components 20 are used for inserting and positioning a circuit board 100. The circuit board 100 can be inserted and engaged with the positioning components 20 from top to bottom. The quick positioning structure also includes a frame 30, a pressing component 40, a driving component 50, and an adjusting component 60. The frame 30 is disposed above the base 10 and is detachably connected to the base 10. The frame 30 can be connected to the base 10 by snap-fit, magnetic attraction, bolt connection, or a top-down insertion assembly structure. Preferably, the frame 30 is assembled with the base 10 by a top-down insertion assembly structure. The insertion assembly structure may include positioning posts disposed on the base 10 and positioning holes disposed on the frame 30, or may include positioning holes disposed on the base 10 and positioning posts disposed on the frame 30. The frame 30 is inserted and installed above the base 10 from top to bottom and can be directly removed upwards. Through the aforementioned plug-in assembly structure, the frame 30 maintains the same installation position each time it is installed above the base 10. Two sets of pressing components 40 are provided above each positioning component 20. The two sets of pressing components 40 above the same positioning component 20 are arranged at intervals in the left-right direction. Each pressing component 40 includes a moving element 410 and a pressing element 420. The moving element 410 can move relative to the frame 30 in the left-right direction. The pressing element 420 can move up and down relative to the moving element 410. The lower end of the pressing element 420 is used to abut against the upper surface of the circuit board 100. The driving component 50 is used to drive all pressing elements 420 to move downwards synchronously. Two sets of adjusting components 60 are provided. One set is linked to the moving element 410 located on the left side of the two sets of pressing components 40 above each positioning component 20. The other set is linked to the moving element 410 located on the right side of the two sets of pressing components 40 above each positioning component 20. The adjustment component 60 is used to move the two moving elements 410 above each positioning component 20 closer to or further away from each other in the left and right direction.

[0025] The positioning assembly 20 includes a support platform 210 disposed on the base 10 and a positioning insertion part 220 disposed on the upper surface of the support platform 210 and protruding upward relative to its upper surface. The support platform 210 is used to support the circuit board 100. The positioning insertion part 220 is used to engage with the positioning holes on the circuit board 100. When the circuit board 100 is inserted from top to bottom, the positioning insertion part 220 is inserted into the positioning holes of the circuit board 100 to achieve initial positioning. Multiple positioning assemblies 20 are arranged in the left-right direction, which can simultaneously support multiple circuit boards 100 or multiple parts of a single circuit board 100.

[0026] A frame 30 is positioned above a base 10. A first sliding groove 320 and a second sliding groove 330 are provided on the front and rear sides of the frame 30. The first and second sliding grooves 320 and 330 can extend in the left-right direction. The first sliding groove 320 can penetrate the front and rear sides of the frame 30 in the left-right direction. The second sliding groove 330 can also extend in the left-right direction. The left and right ends of a movable element 410 are respectively inserted into the first sliding grooves 320 on the front and rear sides. Each movable element 410 has a guide member 412 at its front and rear ends. The guide member 412 is movably inserted into the second sliding groove 330. The guide member 412 can be a grommet. The grommets can adjust the insertion depth and lock. Through the cooperation of the first and second sliding grooves 320 and 330, the movable element 410 can move smoothly in the left-right direction, while restricting its movement in the front-back and up-down directions. The movable element 410 can slide left and right through the first and second sliding grooves 320 and 330.

[0027] The movable element 410 has multiple through holes 411 arranged along the front-to-back direction. The pressing element 420 includes a positioning pin 421 inserted into the through hole 411. By inserting the positioning pin 421 into different through holes 411, the position of the positioning pin 421 in the front-to-back direction can be adjusted according to different circuit boards 100, so that the pressing element 420 corresponds to different flattening positions on the circuit board 100. At the same time, the drive assembly 50 can also be adjusted accordingly in the front-to-back direction. Specifically, the fixing bracket 510 is connected to the mounting holes 310 at different positions on the frame 30 through mounting ears 511 and connecting bolts, so that the pressing rod 520 corresponds to the adjusted positioning pin 421. In this way, the through holes 411, positioning pin 421, pressing rod 520, fixing bracket 510, mounting ears 511 and mounting holes 310 form an adjustable front-to-back fit relationship. The upper end of the positioning pin 421 is provided with a limit end 423. A spring 422 is fitted onto the positioning pin 421 between the upper surface of the moving element 410 and the limiting end 423. The upper end of the spring 422 abuts against the limiting end 423, and the lower end abuts against the upper surface of the moving element 410. The positioning pin 421 can move up and down within the through hole 411. The limiting end 423 is used to prevent the positioning pin 421 from falling out of the through hole 411. The spring 422 is used to reset the positioning pin 421 upward after the drive assembly 50 releases its downward pressure. The drive assembly 50 abuts against the upper surface of the limiting end 423 to drive the positioning pin 421 to move downward. When the drive assembly 50 presses down on the limiting end 423, the positioning pin 421 moves downward against the elastic force of the spring 422, and the lower end of the positioning pin 421 abuts against the upper surface of the circuit board 100. When the drive assembly 50 resets upward, the spring 422 pushes the limiting end 423 upward, and the positioning pin 421 resets accordingly.

[0028] The lower end of the positioning pin 421 is provided with a spherical cavity. An abutment ball 424 is rotatably disposed within the spherical cavity. The abutment ball 424 abuts against the upper surface of the circuit board 100. The abutment ball 424 can rotate within the spherical cavity, thereby adapting to minor unevenness on the upper surface of the circuit board 100 when pressing the circuit board 100, avoiding scratches on the circuit board 100, and making the pressure distribution more uniform.

[0029] The drive assembly 50 includes a fixed frame 510, a pressing rod 520, and an adjusting bolt 530. The left and right ends of the fixed frame 510 are detachably connected to the frame 30. The fixed frame 510 can span the frame 30. The pressing rod 520 is positioned between the fixed frame 510 and the limiting ends 423. The pressing rod 520 is movable vertically relative to the fixed frame 510. The pressing rod 520 can extend in the front-back direction and simultaneously press against multiple limiting ends 423. The left and right ends of the pressing rod 520 are slidably connected to the left and right sides of the fixed frame 510 via sliding sleeves or sliding blocks 523. The sliding sleeves or sliding blocks 523 are fitted onto the columns or vertical guide rods of the fixed frame 510, allowing the pressing rod 520 to move only vertically and not rotate. The adjusting bolt 530 is threadedly connected to the crossbeam of the fixed frame 510, and its lower end is rotatably connected to the pressing rod 520. The height of the pressing rod 520 can be adjusted by rotating the adjusting bolt 530, thereby adjusting the distance or degree of clamping between the pressing rod 520 and the limiting end 423. A knob is connected to the upper end of the adjusting bolt 530. The knob facilitates the operator's rotation of the adjusting bolt 530. Multiple drive assemblies 50 can be provided, each corresponding to a different positioning assembly 20. All pressing elements 420 can move downwards synchronously, or they can be synchronized through the same drive source or linkage mechanism.

[0030] The frame 30 has through holes 411 arranged on its left and right sides, each with a mounting hole 310. The mounting holes 310 are arranged along the front-to-back direction on both sides of the frame 30. The fixing bracket 510 has mounting ears 511 that can correspond to any of the mounting holes 310. The mounting ears 511 are located at both ends of the fixing bracket 510. Connecting bolts, threaded into the mounting holes 310, pass through the mounting ears 511. By connecting the mounting ears 511 to different mounting holes 310, the mounting position of the fixing bracket 510 in the front-to-back direction can be adjusted, thus allowing the pressure rod 520 to correspond to different arrangements of through holes 411 and positioning pins 421. By selecting different mounting holes 310, the front-to-back position of the fixing bracket 510 can be adjusted. By inserting the positioning pin 421 into different through holes 411 and selecting the corresponding mounting hole 310 to connect the mounting ear 511, the pressing element 420 and the drive assembly 50 can be synchronously adjusted in front and behind position according to the specifications of the circuit board 100. The fixing bracket 510 can be fixed to the frame 30 by the mounting ear 511 and connecting bolts.

[0031] The adjusting assembly 60 includes a movable rod 610 and an adjusting screw 620. The movable rod 610 is movable left and right relative to the frame 30. The adjusting screw 620 is threadedly connected to the frame 30, and one end is rotatably connected to the movable rod 610. When the adjusting screw 620 is rotated, the adjusting screw 620 moves left and right relative to the frame 30, thereby driving the movable rod 610 to move in the left and right direction. The movable rod 610 is linked to the movable element 410. The movable rod 610 can be connected to multiple movable elements 410. The movable rod 610 can extend in the front-back direction and simultaneously connect to all movable elements 410 on the same side. In this way, one set of adjusting assemblies 60 can synchronously adjust all movable elements 410 on the same side. Another set of adjusting assemblies 60 synchronously adjusts all movable elements 410 on the other side. The two sets of adjusting assemblies 60 are linked to the movable elements 410 on the left and right sides respectively, thereby causing the two movable elements 410 above the same positioning assembly 20 to move closer or further apart. Therefore, the two moving elements 410 above each positioning component 20 can move closer or further away synchronously, ensuring consistent flattening of multiple circuit boards 100 or multiple parts of a single circuit board 100. This allows the spacing between the pressure points on the left and right sides to be adjusted according to the specifications of the circuit board 100 and the position of the adhesive application area, ensuring that the pressure points accurately act on the left and right sides of the adhesive application area.

[0032] like Figure 6 As shown, the adhesive applicator 70 is located above the circuit board 100 and is used to apply adhesive to the bonding wires on the circuit board 100. The adhesive applicator 70 is moved by a multi-axis robot. The multi-axis robot can be a multi-axis robotic arm commonly used in the art, which is not shown in the figure. During adhesive application, the multi-axis robot drives the adhesive applicator 70 to move from an obliquely upward position above the circuit board 100 and then applies adhesive to the circuit board 100. After adhesive application is completed, the multi-axis robot drives the adhesive applicator 70 to move away from the circuit board 100 from an obliquely upward position. By using an obliquely upward entry method, interference between the adhesive applicator 70 and the frame 30, the pressing assembly 40, the driving assembly 50, and the adjusting assembly 60 can be avoided.

[0033] The working principle is as follows. In use, the circuit board 100 is inserted into the positioning assembly 20 from top to bottom. The positioning insertion part 220 of the positioning assembly 20 is inserted into the positioning hole of the circuit board 100, and the support platform 210 supports the circuit board 100. According to the specifications of the circuit board 100, the adjusting screw 620 is rotated, causing the moving rod 610 to move left and right. The moving rod 610 then causes the corresponding moving element 410 to move in the left and right directions. The two sets of adjusting assemblies 60 respectively adjust the moving elements 410 on the left and right sides, so that the two moving elements 410 above the same positioning assembly 20 move closer or further apart, thereby aligning the pressing element 420 with the left and right sides of the glue application area of ​​the circuit board 100. Then, rotate the adjusting bolt 530 to move the pressing rod 520 downwards. The pressing rod 520 presses against the limiting end 423, which in turn drives the positioning pin 421 downwards. The abutting ball 424 at the lower end of the positioning pin 421 abuts against the upper surface of the circuit board 100, flattening the left and right sides of the glue application area. All pressing components 420 can move downwards synchronously via the drive assembly 50. During glue application, the glue application head 70 is driven by the multi-axis robot to move from an oblique position above the circuit board 100 and apply glue to the solder lines on the circuit board 100. Because the circuit board 100 is flattened on both sides, warping and tilting, as well as glue accumulation, are reduced. After glue application, the frame 30 is removed directly, allowing the pressing assembly 40, drive assembly 50, and adjusting assembly 60 to leave the base 10 along with the frame 30. Then, the circuit board 100 is removed. In the same batch of circuit boards 100 glue application, only the first circuit board 100 requires adjustment of its front-back, left-right, and pressing positions. When applying glue to the second circuit board 100, simply insert the circuit board 100 into the positioning component 20, and then install the frame 30 on top of the base 10; no readjustment is required.

[0034] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
