Description

TECHNICAL FIELD

[0001] The application relates to the technical field of circuit board processing, and in particular to a circuit board processing device capable of preventing deviation. BACKGROUND

[0002] The circuit board is the core carrier of an electronic device, and is used for connecting and supporting electronic components to realize circuit functions. When the electronic components on the circuit board are welded, a chip mounter and reflow soldering are usually used for processing. However, when special components (such as high-precision FPC connectors) are welded, very precise alignment and landing point control are required. In particular, when a flexible circuit board is processed, the flexible substrate is more susceptible to high temperatures and is prone to deformation compared with a rigid FR4 board. When immersed in a high-temperature tin pool, the flexible circuit board is prone to warping and deformation. The traditional process fixes the flexible circuit board on a horizontal rigid platform for welding, resulting in a planar layout of the spatial arrangement of the electronic components. When the circuit board is wound in an actual installation mode, the components are not matched with the curved surface due to the position angle, causing mutual extrusion and collision, which may result in pin deformation or even welding point fracture and short circuit.

[0003] Therefore, a circuit board fixing device for PCB circuit board welding is disclosed in Chinese Patent No. CN119545675B, which designs a multi-axis adjustment system that cooperates with an adjustable polishing and welding mechanism and a clamping and fixing mechanism. The flexible circuit board is dynamically fitted with an arc, vertically positioned at multiple angles, and independently and accurately controlled by the polishing head and the welding head through an electric telescopic rod and a threaded rod linkage motor. The device solves the problems of dynamic fixing and cooperative control of curved surface vertical processing of the flexible circuit board in a non-planar state, and realizes that the polishing / welding tool is always perpendicular to the arbitrary arc section through real-time adjustment of the position and posture of the multi-stage motor + telescopic rod. The device solves the problems of drilling deviation, welding deformation and electronic component collision caused by the failure of the traditional clamp to synchronously fix and profile process the flexible circuit board in the installation scene with an arc, and ensures that the circuit board is accurately processed according to the installation arc.

[0004] However, when welding or drilling is performed, if the processing position is in a suspended area between the two support bodies, the suspended area will be locally deformed due to the lack of support. When drilling is performed, the drill bit cannot penetrate vertically, resulting in an inclined hole wall or tearing of the copper foil. When welding is performed, the welding points are not tightly attached to the circuit board, resulting in cold welding or cavities, which affects the processing quality. SUMMARY

[0005] In view of the above problems, a circuit board processing device capable of preventing deviation is provided, which solves the problem of local deformation and damage caused by processing of the flexible circuit board in the support gap through a rack, a processing manipulator, a curved surface profiling mechanism, a clamping mechanism and an adjustment mechanism.

DETAILED DESCRIPTION

[0031] ​In order to further understand the features, technical means and specific purposes and functions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0032] Referring to Figure 1 and Figure 2 : An anti-deviation integrated circuit circuit board processing equipment, comprising a rack 1 and a processing manipulator 2 for processing the circuit board; The rack 1 is provided with a curved surface profiling mechanism 3 for simulating an arc-shaped mounting surface, the curved surface profiling mechanism 3 comprises at least three profiling plates 31 capable of lifting in the vertical direction, and adjacent profiling plates 31 are hinged to each other; The rack 1 is provided with two groups of clamping mechanisms 4 for clamping both ends of the circuit board, and the two groups of clamping mechanisms 4 are distributed on both sides of the curved surface profiling mechanism 3; The rack 1 is provided with an adjusting mechanism 5 for controlling the horizontal translation of the clamping mechanism 4.

[0033] The present application realizes the function of stabilizing the support of the circuit board through the rack 1, the processing manipulator 2, the curved surface profiling mechanism 3, the clamping mechanism 4 and the adjusting mechanism 5. The clamping mechanism 4 is moved by the adjusting mechanism 5, and then the circuit board is moved by the two groups of clamping mechanisms 4, so as to accurately adjust the position of the circuit board during processing. The processing position is on the profiling plate 31, avoiding the processing point being at the connection of adjacent profiling plates 31 to affect the processing quality, solving the problem of local deformation damage caused by flexible circuit board processing in the support gap. The processing manipulator 2 can be a welding manipulator or a drilling manipulator, and the welding manipulator is shown in the drawings of the present application. The profiling plate 31 is a rectangular plate. The rack 1 is provided with a controller for human-computer interaction, and the adjusting mechanism 5 is electrically connected with the controller.

[0034] During processing, the operator first installs both ends of the circuit board to the two groups of clamping mechanisms 4 respectively, and clamps both ends of the circuit board by the two groups of clamping mechanisms 4. Then control the lifting of multiple profiling plates 31 to simulate the installation arc surface of the circuit board. In this process, the position of the clamping mechanism 4 is adjusted by the adjusting mechanism 5, so that the circuit board is in a tensioned state, and at the same time the circuit board is in close contact with the profiling plate 31. Then the circuit board is processed by the processing manipulator 2, and the position of the clamping mechanism 4 is adjusted according to the processing position during processing, so as to ensure that the processing position can be placed on the profiling plate 31, avoiding affecting the processing quality due to excessive local deformation of the circuit board during processing.

[0035] Referring to Figure 3 and Figure 4 : The processing manipulator 2 is provided with a photoelectric sensor 21 for positioning; Each profiling plate 31 is provided with a reflecting plate 311 for cooperating with the photoelectric sensor 21.

[0036] The application realizes the function of accurately positioning the position of the profiling plate 31 through the cooperation of the photoelectric sensor 21 and the reflecting plate 311. The photoelectric sensor 21 is electrically connected with the controller. The photoelectric sensor 21 is integrated with a light beam emitter and a receiver. During processing, the processing manipulator 2 is controlled to move so that the processing end of the processing manipulator 2 is horizontally aligned with the set processing position. At this time, if the light beam emitted by the photoelectric sensor 21 is not accurately docked with the reflecting plate 311, the receiver cannot receive the light signal. Then the clamping mechanism 4 is controlled to move a specified distance through the adjusting mechanism 5, the clamping mechanism 4 drives the circuit board to move, and at the same time the processing manipulator 2 also moves. During the movement, if the light beam emitted by the photoelectric sensor 21 is reflected to the receiver through the reflecting plate 311, the receiver receives the light signal, and then feeds back the signal to the controller. The controller controls the adjusting mechanism 5 to stop driving the clamping mechanism 4, at this time the processing position of the circuit board is completely on the upper plane of the profiling plate 31, and through the supporting action of the profiling plate 31, the stability of processing is improved, and the processing quality is guaranteed.

[0037] With reference to Figure 1 , Figure 2 and Figure 5 : The lower part of the profiling plate 31 is provided with a first support 32, and the first support 32 is provided with a first hinged seat 321 hinged with the profiling plate 31; the rack 1 is provided with a linear driver 33 for driving the first support 32 to ascend and descend; the rack 1 is provided with a guide assembly 34 for limiting the first support 32 to be in a vertical state.

[0038] The application realizes the function of controlling the profiling plate 31 to ascend and descend through the first support 32, the linear driver 33 and the guide assembly 34, achieves the effect of simulating the arc-shaped mounting surface of the circuit board through the cooperation of multiple profiling plates 31, and through the setting of the guide assembly 34, the first support 32 can always be in a vertical state, maintaining the stability of supporting the profiling plate 31. Each profiling plate 31 corresponds to a linear driver 33, the linear driver 33 is a linear cylinder, and the linear driver 33 is electrically connected with the controller. In the working state, the operator first cooperates the two ends of the circuit board with two sets of clamping mechanisms 4. Then the curvature of the curved profiling mechanism 3 is adjusted according to the mounting surface of the circuit board. Multiple profiling plates 31 are driven to ascend and descend through multiple linear drivers 33, and the vertical state of the first support 32 is maintained through the guide assembly 34 during the ascending and descending process. After the adjustment is completed, the clamping mechanism 4 is controlled to move through the adjusting mechanism 5, so that the circuit board is tightly attached to the curved profiling mechanism 3.

[0039] With reference to Figure 2 and Figure 5The first support 32 at the bottom of one of the profiling plates 31 is provided with a main rod 341, and the first support 32 at the bottom of the rest of the profiling plates 31 is provided with a secondary rod 342; the first support 32 connected with the main rod 341 is provided with a first guide rod 3411 in sliding fit with the rack 1; the secondary rod 342 is provided with a sliding block 3421 capable of ascending and descending, and the sliding block 3421 and the main rod 341 are both hinged with two connecting rods 343, and the connecting rods 343 on the adjacent first supports 32 are hinged with each other to form a parallelogram structure.

[0040] The main rod 341, the secondary rod 342, the connecting rod 343 and the sliding block 3421 are used to realize the function of keeping the first support 32 in a vertical state during the control of the ascending and descending of the first support 32. A linear sliding groove is formed in the secondary rod 342, and the sliding block 3421 is in sliding fit with the linear sliding groove. When the heights of the adjacent profiling plates 31 are different, the spacing between the two first supports 32 will also change. In order to maintain the supporting stability of the first support 32, the main rod 341 and the secondary rod 342 are arranged. The linear sliding groove in the secondary rod 342 can guide the sliding block 3421 to move in a straight line, and the spacing between the hinged points of the sliding block 3421 and the two connecting rods 343 is equal to the spacing between the two hinged points and the main rod 341. The first support 32 connected with the main rod 341 always ascends and descends in a vertical direction through the guidance of the first guide rod 3411, and the main rod 341 and the sliding block 3421 are kept parallel through the parallelogram structure. During the control of the ascending and descending of the first support 32, the guiding assembly 34 controls all the first supports 32, the main rod 341 and the secondary rod 342 to keep in a vertical state, thereby improving the supporting stability of the first support 32 to the profiling plate 31.

[0041] Referring to Figure 2 , Figure 6 and Figure 7 : The linear driver 33 is connected with a mounting plate 331; the rack 1 is provided with a second support 11, and the second support 11 is connected with a second guide rod 111 for guiding the mounting plate 331 to slide in a horizontal direction.

[0042] The linear driver 33, the second support 11 and the second guide rod 111 are used to realize the function of controlling the linear driver 33 and the first support 32 to keep in synchronization in a horizontal direction. When the spacing between the adjacent first supports 32 changes, the spacing between the two linear drivers 33 driving the adjacent first supports 32 also changes. The second guide rod 111 extends in a horizontal direction, so that the second guide rod 111 can stably guide the mounting plate 331 and the linear driver 33 to move. Further, the linear driver 33 can stably drive the first support 32 to ascend and descend, without affecting the change of the spacing between the first supports 32, thereby avoiding affecting the connection strength of the adjacent profiling plates 31.

[0043] Referring to Figure 2 and Figure 7The mounting plate 331 is provided with a plurality of rollers 3311 which are rotatably arranged on the mounting plate 331 and are in rolling connection with the second guide rod 111.

[0044] The present application achieves the function of replacing sliding friction with rolling friction by the rollers 3311, thereby reducing the abrasion of the mounting plate 331 and the second guide rod 111. The four rollers 3311 are evenly divided into two groups, and the two rollers 3311 in the same group are at the same height. The two groups of rollers 3311 support the mounting plate 331 to move stably along the second guide rod 111.

[0045] Referring to Figure 1 and Figure 9 The clamping mechanism 4 comprises a support plate 41, a pressing plate 42 and an elastic connecting piece 43. The pressing plate 42 is connected with the support plate 41 through the elastic connecting piece 43.

[0046] The present application achieves the function of clamping the circuit board by the support plate 41, the pressing plate 42 and the elastic connecting piece 43. The pressing plate 42 is provided with a handle 421, and the adjusting mechanism 5 is used to drive the elastic connecting piece 43 to move. When installing the circuit board, first move the end of the circuit board to the support plate 41, then the operator holds the handle 421 and lifts the pressing plate 42. The elastic connecting piece 43 is elongated under the action of tension. The operator inserts the end of the circuit board between the pressing plate 42 and the support plate 41, then releases the handle 421. The pressing plate 42 presses the end of the circuit board on the support plate 41 under the action of the elastic force of the elastic connecting piece 43. When adjusting the position of the circuit board, the elastic connecting piece 43 is controlled to move by the adjusting mechanism 5, and the support plate 41 and the pressing plate 42 are driven to move, thereby driving the circuit board to move.

[0047] Referring to Figure 1 and Figure 9 The elastic connecting piece 43 comprises a bottom plate 431 and a first elastic member 432. The bottom plate 431 is connected with the support plate 41, and the bottom plate 431 is provided with an extension rod 4311 which is in sliding cooperation with the pressing plate 42. The two ends of the first elastic member 432 are respectively connected with the bottom plate 431 and the pressing plate 42.

[0048] The present application achieves the function of connecting the support plate 41 and the pressing plate 42 by the bottom plate 431, the first elastic member 432 and the extension rod 4311, and controls the opening and closing of the pressing plate 42 by the cooperation of the first elastic member 432 and the extension rod 4311 to clamp the circuit board. When the operator pulls and lifts the handle 421, the first elastic member 432 is elongated under the action of tension. By the arrangement of the extension rod 4311, the support plate 41 is guided to move, thereby avoiding the deviation of the support plate 41 from the bottom plate 431.

[0049] Referring to Figure 1 and Figure 10The first guide rail 51 and the second guide rail 52 are arranged on the rack 1 and used for guiding the movement of the pressing plate 42 and the bottom plate 431 respectively; and the linear driving assembly 53 is arranged on the rack 1 and used for driving the movement of the bottom plate 431 along the second guide rail 52.

[0050] The first guide rail 51, the second guide rail 52 and the linear driving assembly 53 are used to realize the function of driving the movement of the clamping mechanism 4. The linear driving assembly 53 comprises a rotary driver 531, a screw rod 532, two bevel gears 533 and a third guide rod 534. The rotary driver 531 is arranged on the rack 1, the screw rod 532 is arranged on the rack 1 in a rotating mode, the two bevel gears 533 are arranged in a sleeving mode on the driving end of the rotary driver 531 and the screw rod 532 respectively and are connected in a meshing mode. The screw rod 532 is connected with the bottom plate 431 in a threaded mode, and the third guide rod 534 is connected with the bottom plate 431 in a sliding mode. The rotary driver 531 is preferably a servo motor, and the rotary driver 531 is electrically connected with a controller. During the processing, when the position of the circuit board needs to be adjusted, the controller sends a signal to the rotary driver 531, the rotary driver 531 drives the screw rod 532 to rotate through the bevel gears 533 after receiving the signal, and the screw rod 532 drives the movement of the bottom plate 431 connected with the screw rod 532 in a threaded mode. The bottom plate 431 drives the movement of the supporting plate 41 and the pressing plate 42, and then the position of the circuit board is adjusted.

[0051] Referring to Figure 1 and Figure 10 The driving end of the linear driver 33 is provided with a second elastic member 332, and a damping rod is sleeved on the second elastic member 332. The first support 32 is provided with a push plate 35, and the second elastic member 332 is connected with the push plate 35.

[0052] The second elastic member 332 and the push plate 35 are used to realize the function of maintaining the tension of the circuit board. The push plate 35 is fixedly connected with the main rod 341 or the auxiliary rod 342 through a connecting seat 351 arranged on the push plate 35. When the adjusting mechanism 5 controls the movement of the clamping mechanism 4 to tension the circuit board, the second elastic member 332 is contracted under the action of tension, and the second elastic member 332 is prevented from frequently shaking under the action of elastic force through the arrangement of the damping rod. The circuit board is protected when the tension increases, and the circuit board is prevented from being damaged due to sudden increase of tension.
