Description

Technical Field

[0001] This invention relates to the field of flexible printed circuit board (FPCB) testing technology, and more particularly to a FPCB production testing device. Background Technology

[0002] As flexible circuit boards, FPC boards require defect inspection after production. Traditional inspection relies on manual loading, and because the flexible FPC boards need to be fixed to a plate, only 2-3 boards can be placed at a time, resulting in low inspection efficiency. A patent with publication number CN222070492U solves this problem by setting multiple vertical placement plates on a rotary table, combined with a suction mechanism consisting of cylinders, telescopic rods, and vacuum suction cups. This mechanism can pull out the placement racks within the placement plates, exposing the fixed plate with the FPC board for inspection. After inspection, a spring returns the board to its original position, enabling continuous loading and solving the problems of tedious manual loading and limited capacity. However, several issues remain: vertical inspection by attaching the FPC board to the fixed plate limits inspection to one side only; vertical inspection is also prone to unevenness due to gravity, affecting inspection results; and the attachment process is cumbersome and can easily damage the FPC board. Summary of the Invention

[0008] Furthermore, both the blowing pipe and the suction pipe are configured as two pipes or have two inner pipes, which are connected to the first FPC placement plate and the second FPC placement plate through a connector; allowing the first FPC placement plate and the second FPC placement plate to perform blowing or suction work independently.

[0009] Furthermore, it also includes a mounting shell and a collection box; two waste discharge holes are opened on the left side of the mounting platform, and the mounting shell is fixedly connected to the waste discharge holes; the collection box is detachably connected to the bottom of the mounting shell.

[0010] Furthermore, both the first FPC placement plate and the second FPC placement plate consist of a mounting frame and a perforated plate rotatably connected to the mounting frame; a torsion spring is provided at the pivot of the mounting frame and the perforated plate, and the torsion spring forces the perforated plate to rotate toward the limit strip so that the perforated plate is located in the mounting frame when no force is applied.

[0011] Furthermore, it also includes an electric push rod, which is installed on the mounting housing and pushes the perforated plate to rotate relative to the mounting frame.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0025] Example 1: As Figures 1-9 As shown, a flexible printed circuit board (FPCB) production and testing device includes a mounting platform 1, a feeding turntable 2, detectors 3, and a sliding frame 4. The feeding turntable 2 is mounted on the mounting platform 1 and has multiple slots 2a. A sliding frame 4 is inserted into each slot 2a and can slide within the slot 2a. Two detectors 3 are mounted on the left side of the mounting platform 1. A gripping assembly is used to slide and pull the sliding frame 4 out of the slot 2a. Figure 2 As shown, when the sliding frame 4 is pulled out, a portion of the structure at the tail of the sliding frame 4 remains in the slot 2a, which serves two purposes: first, to facilitate re-insertion, and second, to maintain stability.

[0026] A rotating plate 41 is rotatably connected to the bottom of the sliding frame 4; a first FPC placement plate 42 is rotatably connected to one side of the rotating plate 41, and a second FPC placement plate 43 is rotatably connected to the other side; the first FPC placement plate 42 or the second FPC placement plate 43 is rotated to a horizontal state by a drive assembly, and the horizontal FPC plate is visually inspected by a detector 3. It should be noted that the rotation of the rotating plate 41, the first FPC placement plate 42, and the second FPC placement plate 43 are all equipped with damping (damping shaft, damping pad), and they cannot rotate freely without force.

[0027] The gripping assembly includes an electric guide rail 101, an electric slider 102, a connecting frame 103, an electric magnetic chuck 104, and a magnetic chuck 105. The electric guide rail 101 is installed at the bottom of the mounting platform 1, and the electric slider 102 is slidably connected to the electric guide rail 101. The connecting frame 103 is fixedly connected to the electric slider 102. The electric magnetic chuck 104 is installed on the upper side of the connecting frame 103. The magnetic chuck 105 is fixedly connected to the side of the sliding frame 4. The magnetic chuck 105 can be an iron sheet. By moving the electric magnetic chuck 104 to magnetically attract the magnetic chuck 105, the sliding frame 4 is slidably pulled out of the slot 2a.

[0028] The drive assembly includes a driver 201; the driver 201 is mounted on the electric slider 102; the driver 201 has a first telescopic shaft 2011, a second telescopic shaft 2012 and a third telescopic shaft 2013, the first telescopic shaft 2011, the second telescopic shaft 2012 and the third telescopic shaft 2013 can extend and rotate independently.

[0029] The first telescopic rotating shaft 2011 is adapted to be inserted into the rotating shaft of the rotating plate 41, the second telescopic rotating shaft 2012 is adapted to be inserted into the rotating shaft of the first FPC placement plate 42 and the second FPC placement plate 43, and the third telescopic rotating shaft 2013 is adapted to be inserted into the rotating shaft of the first FPC placement plate 42 and the second FPC placement plate 43; wherein the telescopic rotating shaft can be implemented by moving the motor through the slide rail and the motor driving the rotating shaft to rotate, or other implementation methods in the prior art.

[0030] It also includes magnets 44. Magnets 44 are fixed to the opposing sides of the first FPC placement plate 42 and the second FPC placement plate 43. Initially, the magnetic attraction of the magnets 44 keeps the first FPC placement plate 42 and the second FPC placement plate 43 close together and limits and fixes the FPC plate. When the first FPC placement plate 42 and the second FPC placement plate 43 rotate and separate, they overcome the magnetic attraction of the magnets 44.

[0031] As flexible circuit boards, FPC boards require defect inspection after production. Traditional inspection relies on manual loading, and because the flexible FPC boards need to be fixed to a plate, only 2-3 boards can be placed at a time, resulting in low inspection efficiency. A patent with publication number CN222070492U solves this problem by setting multiple vertical placement plates on a rotary table, combined with a suction mechanism consisting of cylinders, telescopic rods, and vacuum suction cups. This mechanism can pull out the placement racks within the placement plates, exposing the fixed plate with the FPC board for inspection. After inspection, a spring returns the board to its original position, enabling continuous loading and solving the problems of tedious manual loading and limited capacity. However, several issues remain: vertical inspection by attaching the FPC board to the fixed plate limits inspection to one side only; vertical inspection is also prone to unevenness due to gravity, affecting inspection results; and the attachment process is cumbersome and can easily damage the FPC board.

[0032] When using this invention, the FPC board is placed between the first FPC placement plate 42 and the second FPC placement plate 43. The FPC board is bidirectionally clamped and fixed by the first FPC placement plate 42 and the second FPC placement plate 43. The magnet 44 maintains the clamping force, making the operation convenient. It does not require complicated pasting operations and will not damage the FPC board. At the same time, the first FPC placement plate 42 and the second FPC placement plate 43 can be slotted according to the shape of the FPC board to adapt to the shape of the FPC board.

[0033] Then as Figure 1 As shown, the sliding frame 4 (first FPC placement plate 42, second FPC placement plate 43, FPC plate) is placed into the slot 2a of the feeding turntable 2 by the worker or machine equipment. The feeding turntable 2 drives the slot 2a to rotate, and the sliding frame 4 (first FPC placement plate 42, second FPC placement plate 43, FPC plate) is transferred to the gripping component in an orderly manner. Through the joint action of the gripping component, the driving component and the detector 3, the FPC plate is subjected to double-sided flat detection operation.

[0034] Specifically: such as Figure 2 , Figure 3 As shown, firstly, the electric slider 102 is controlled to slide to the right on the electric guide rail 101, thereby driving the connecting frame 103 and the electric magnetic chuck 104 to move to the right, so that the electric magnetic chuck 104 contacts the magnetic chuck 105 to the right. The electric magnetic chuck 104 is then controlled to electromagnetically attract the magnetic chuck 105. At the same time, the first telescopic rotating shaft 2011 is controlled to extend and insert into the rotating shaft of the rotating plate 41. Then, the electric slider 102 is controlled to slide to the left on the electric guide rail 101, so that the electric magnetic chuck 104 moves to the left, driving the magnetic chuck 105 and the sliding frame 4 to move to the left, thus sliding the sliding frame 4 out of the slot 2a. Figure 3 The state shown.

[0035] Then as Figure 3 , Figure 4 As shown, the first telescopic rotating shaft 2011 is controlled to rotate, causing the rotating plate 41 to rotate from a horizontal state to a vertical state. Consequently, the rotating shaft of the first FPC placement plate 42 is aligned with the third telescopic rotating shaft 2013, and the rotating shaft of the second FPC placement plate 43 is aligned with the second telescopic rotating shaft 2012. Simultaneously, the first FPC placement plate 42 and the second FPC placement plate 43 rotate from a vertical state to a horizontal state. Then, the third telescopic rotating shaft 2013 is controlled to extend and insert into the rotating shaft of the first FPC placement plate 42, and the second telescopic rotating shaft 2012 is controlled to extend and insert into the rotating shaft of the second FPC placement plate 43, presenting the following arrangement: Figure 4 The state shown.

[0036] Then as Figure 4 , Figure 5 , Figure 6As shown, the second telescopic rotating shaft 2012 is controlled to rotate, causing the second FPC placement plate 43 to rotate to a vertical position, overcoming the magnetic attraction of the magnet 44, separating the first FPC placement plate 42 and the second FPC placement plate 43 to expose the FPC board. The FPC board is then positioned at the detection station of one of the detectors 3. The detector 3 is then controlled to perform a horizontal detection on the FPC board, presenting... Figure 5 As shown, the FPC board is set horizontally for testing to avoid unevenness caused by gravity when set vertically, which would affect the testing results.

[0037] After completing the inspection of one side of the FPC board, the system controls the invention to sequentially... Figure 5 Status Reset Figure 4 state, Figure 3 The system then controls the first FPC placement plate 42 and the second FPC placement plate 43 to rotate towards another detector 3 until they reach a horizontal position, thus detecting the other side of the FPC plate. After detecting one FPC plate, the system is controlled to reset. Figure 2 The state is then controlled, and the electric magnetic chuck 104 is used to magnetically attract the magnetic chuck 105 and move to the right, so that the sliding frame 4 is inserted back into the slot 2a.

[0038] Thus, by using the first FPC placement plate 42 and the second FPC placement plate 43 to clamp and fix the FPC board on both sides, the present invention eliminates the need for pasting the FPC board, making operation convenient and preventing damage to the FPC board. Furthermore, by rotating the first FPC placement plate 42 and the second FPC placement plate 43 to a horizontal position, the horizontal FPC board can be inspected, avoiding unevenness caused by gravity when the FPC board is vertically positioned, which would affect the inspection results. Additionally, by sequentially rotating the first FPC placement plate 42 and the second FPC placement plate 43 towards the two detectors 3 to a horizontal position for inspection, double-sided inspection of the FPC board can be achieved. These improvements overcome the shortcomings of the prior art.

[0039] Furthermore, the first FPC placement plate 42 and the second FPC placement plate 43 are provided with several through holes, and also include an air blowing pipe 301, an air suction pipe 302, and a connector 303; the air blowing pipe 301 and the air suction pipe 302 are fixedly connected to the connecting frame 103; the connector 303 is installed on the sliding frame 4, and the connector 303 is plugged into and adapted to the air blowing pipe 301 and the air suction pipe 302. The connector 303 is in gas communication with the first FPC placement plate 42 and the second FPC placement plate 43 (specifically, the connector 303 can be connected to the first FPC placement plate 42 and the second FPC placement plate 43 for air communication through an air pipe); when the air blowing pipe 301 blows air or the air suction pipe 302 draws air, the through holes on the first FPC placement plate 42 and the second FPC placement plate 43 are used for blowing or drawing air. The air blowing pipe 301 and the air suction pipe 302 are made of rigid material.

[0040] The blowing pipe 301 and the suction pipe 302 are both configured as two pipes or have two inner pipes, each connected to the first FPC placement plate 42 and the second FPC placement plate 43 through the connector 303, so that the first FPC placement plate 42 and the second FPC placement plate 43 are each connected to a blowing pipe 301 and a suction pipe 302 (or each is connected to a single inner pipe of the blowing pipe 301 and the suction pipe 302); allowing the first FPC placement plate 42 and the second FPC placement plate 43 to perform blowing or suction work independently.

[0041] It should be noted that while the electric magnetic chuck 104 moves the magnetic suction component 105 to the right, the air blowing pipe 301 and the air suction pipe 302 are simultaneously inserted into the connector 303.

[0042] Before the first FPC placement plate 42 and the second FPC placement plate 43 are opened to expose the FPC board for testing, the air blowing pipe 301 blows air and the air suction pipe 302 sucks air, such as Figure 4 In an example scenario, the second FPC placement plate 43, located above the FPC board, blows air downwards to remove any dust that may be present on the surface of the FPC board to be inspected. Simultaneously, the first FPC placement plate 42, located below the FPC board, draws air to adsorb the FPC board. In this way, by blowing air upwards and drawing air downwards, the stability of the FPC board during dust removal is maintained. Furthermore, when the first FPC placement plate 42 and the second FPC placement plate 43 are open, the air drawn from the bottom of the FPC board can overcome intermolecular forces and atmospheric pressure differences, ensuring that the FPC board is not carried out when the first FPC placement plate 42 and the second FPC placement plate 43 are open.

[0043] Furthermore, it also includes a mounting shell 401 and a collection box 402; two waste discharge holes are opened on the left side of the mounting platform 1, and the mounting shell 401 is fixedly connected to the waste discharge holes; the collection box 402 is detachably connected to the bottom of the mounting shell 401.

[0044] Both the first FPC placement plate 42 and the second FPC placement plate 43 consist of a mounting frame a and a perforated plate b rotatably connected to the mounting frame a. A torsion spring is provided at the pivot point between the mounting frame a and the perforated plate b. The torsion spring forces the perforated plate b to rotate towards the limiting strip c, so that the perforated plate b is located in the mounting frame a when no force is applied. The connector 303 is in gas communication with the perforated plate b via an air pipe. An electric push rod 403 is also included. The electric push rod 403 is mounted on the mounting housing 401, and pushes the perforated plate b to rotate relative to the mounting frame a. A rectangular block is fixed to the telescopic part of the electric push rod 403.

[0045] The collection box 402 has a vertical channel with the same outline as the FPC board, so that unqualified FPC boards can be stacked vertically from bottom to top, avoiding messy stacking.

[0046] When detector 3 detects a defective FPC board, the defective FPC boards need to be collected and processed, such as... Figure 7 , Figure 8 As shown, the third telescopic shaft 2013 is controlled to rotate, causing the first FPC placement plate 42 to flip downwards, and then the FPC plate slides down into the collection box 402.

[0047] This can be achieved by providing a vertical channel within the collection box 402 that is the same as or slightly larger than the outline of the FPC board, such as... Figure 9 As shown, when the first FPC placement plate 42 rotates to a downward tilted state, the suction effect of the perforated plate b on the FPC plate is maintained, allowing the FPC plate to continue to adhere to the perforated plate b. Then, the telescopic part of the electric push rod 403 is controlled to push the rectangular block to move towards the perforated plate b. The electric push rod 403 pushes the perforated plate b to rotate relative to the mounting frame a, overcoming the torsion spring force and pushing the perforated plate b to a horizontal state. In this way, the FPC plate is transferred to the vertical channel above the collection box 402, and the FPC plate is in a horizontal state. Then, the suction effect of the perforated plate b on the FPC plate is canceled, and the FPC plate falls downward into the vertical channel. This realizes the vertical stacking of FPC plates from bottom to top, avoiding messy stacking.
