Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, in particular to a circuit board rolling device for manufacturing integrated optoelectronic devices. Background Art

[0002] To achieve the desired results when manufacturing integrated optoelectronic devices, specialized equipment is required. Flexible circuit boards (FPCBs) are often chosen for high-level integration because they offer excellent electrical performance, meet the needs of smaller and higher-density designs, and help reduce assembly steps and enhance reliability. The processing of FPCBs often requires rolling to combine the circuitry and pads, requiring specialized equipment specifically designed for the manufacture of integrated optoelectronic devices.

[0003] Existing circuit board rolling devices used in the manufacture of integrated optoelectronic devices can usually only roll circuit boards of a single thickness when in use. It is difficult to adjust the rolling pressure, roller speed and circuit board feed rate according to the thickness of the circuit board, resulting in the need for different equipment to roll circuit boards of different thicknesses, which can easily affect the manufacturing efficiency of integrated optoelectronic devices. When the length and width of the circuit board are the same and the thickness is in a thinner range, the pressure increases linearly with increasing thickness. At this time, a lower feed rate and a higher roller speed are required; when the circuit board is in a thicker range, the pressure increases nonlinearly with increasing thickness (that is, for every fixed increase in thickness, the pressure needs to increase according to the corresponding gradient), but the change in thickness is large for the pressure to change. At this time, a higher feed rate and a lower roller speed are required. When the circuit board thickness is in a medium range, the pressure still increases nonlinearly with increasing thickness, but a small change in thickness can trigger a change in pressure. At this time, a medium feed rate and a medium roller speed are required. Summary of the Invention

When the thickness of the circuit board is in the thickest range, the adjustment of the rolling pressure is triggered every time a first preset value changes. When the thickness of the circuit board is in a relatively thick range, the adjustment of the rolling pressure is triggered every time a second preset value changes, and the first preset value is greater than the second preset value, thereby realizing graded pressure reduction control under thick plate working conditions. When the thickness of the circuit board is in the thinnest range, the pressure is continuously adjusted along with the thickness change through a linear pressure compensation mechanism. The device can avoid damage or deformation of the circuit board due to excessive pressure, and avoid poor rolling effect due to insufficient pressure, which can be more conducive to the manufacture of integrated optoelectronic devices and improve the manufacturing efficiency of integrated optoelectronic devices. In the present invention, the speed of the pressing roller is synchronously driven by a speed change mechanism to dynamically adapt to the feed speed. When the thick plate is depressurized, the rolling speed is increased to improve efficiency, and when the thin plate is pressurized, the precision pressing is decelerated to ensure accuracy. This forms a closed-loop coordinated control of thickness, pressure, speed, and feed speed. This ensures that the optimal process parameters are always matched during the rolling process of circuit boards of different thicknesses, and comprehensively optimizes the rolling processing quality of circuit boards of different thicknesses. In the present invention, through the coordinated use of the speed change mechanism and the transmission assembly, the pressure roller and the feed roller can be made to rotate synchronously in opposite directions, and the rotation speeds of the pressure roller and the feed roller are inversely proportional, thereby achieving dynamic matching of the pressure roller's fast speed and the feed roller's slow speed, avoiding low processing efficiency caused by the slow speed of the pressure roller and the feed roller, and avoiding poor rolling effect caused by the fast speed of the pressure roller and the feed roller.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 The present invention provides a technical solution: a circuit board rolling device for manufacturing integrated optoelectronic devices, comprising a workbench 1, the top of the workbench 1 is slidably connected to a base plate 12, a C-shaped frame 11 is fixed on the top of the workbench 1, and the top of the C-shaped frame 11 is connected to a first cylinder 2.

[0022] The driving end of the first cylinder 2 is connected to a rolling mechanism 3, which is used to control the pressure according to the thickness of the circuit board. One side of the rolling mechanism 3 is connected to a speed change mechanism 4, which is used to control the rotation speed according to the thickness of the circuit board. The other side of the speed change mechanism 4 is connected to a feed mechanism 5, which is used to control the feed speed according to the rotation speed. It should be noted that the first cylinder 2 extends the same length each time, causing the rolling mechanism 3 to descend the same distance. After the circuit board is placed on the base plate 12, it is secured by a fixing device. The fixing device can be a starting clamp, a vacuum suction device, or other equipment that can fix the circuit board without affecting the rolling operation of the circuit board. This device is specialized equipment for manufacturing integrated optoelectronic devices and can apply different pressures to the circuit board according to its thickness, thereby achieving rolling.

[0023] In this embodiment, Figures 2 to 5 As shown, the rolling mechanism 3 includes a lifting plate 31 connected to the driving end of the first cylinder 2, the bottom of the lifting plate 31 is connected to a nonlinear adjustment mechanism, the bottom of the nonlinear adjustment mechanism is connected to a fixed plate 35, and the top of the fixed plate 35 is provided with pillars 36 on both sides, and the pillars 36 cooperate with the holes set on both sides of the lifting plate 31.

[0024] The bottom of the fixed plate 35 is connected to a linear adjustment mechanism 316. One side of the linear adjustment mechanism 316 is connected to a second telescopic member 324, which is in turn connected to the nonlinear adjustment mechanism. It should be noted that the nonlinear adjustment mechanism is used to adjust the nonlinear pressure. When the thickness of the circuit board is between the thickest and relatively thick ranges, and the rolling mechanism 3 descends to a set value, the nonlinear adjustment mechanism reduces the pressure.

[0025] In this embodiment, Figures 2 to 5 As shown, the nonlinear adjustment mechanism includes: Reset assembly 32, the reset assembly 32 is connected to both sides of the lifting plate 31; A reciprocating assembly 38, the reciprocating assembly 38 is fixedly connected to the bottom of the lifting plate 31; The guide groove 37 is provided on the outer side of the support 36 and cooperates with the reciprocating assembly 38; A sliding plate 321 is slidably connected to the inner side of the C-shaped frame 11; A locking assembly, which is fixedly connected to one side of the C-shaped frame 11 and is connected to the sliding plate 321; Grooves 322 are provided on one side of the sliding plate 321, with the top groove 322 being larger than the bottom groove 322. Grooves 322 cooperate with the reciprocating assembly 38. It should be noted that when the linear adjustment mechanism 316 descends, the sliding plate 321 descends with the linear adjustment mechanism 316 due to its own gravity. When the linear adjustment mechanism 316 contacts the circuit board, the sliding plate 321 is secured by a locking assembly. A rectangular groove is provided on one side of the C-frame 11, and the groove body of the rectangular groove is slidably connected to the sliding plate 321.

[0026] In this embodiment, Figure 2 As shown, the locking assembly includes a third cylinder 323 fixedly connected to one side of the C-frame 11.

[0027] The sliding plate 321 is provided with a plurality of slots on one side, which cooperate with the driving end of the third cylinder 323. It should be noted that when the linear adjustment mechanism 316 just contacts the circuit board, the driving end of the third cylinder 323 enters the corresponding slot, thereby limiting the position of the sliding plate 321.

[0028] In this embodiment, Figures 2 to 5 As shown, the reset assembly 32 includes a lifting rod 33 slidably connected to both sides of the lifting plate 31 and a first spring 34 sleeved on the top of the lifting rod 33. The bottom end of the lifting rod 33 passes through the lifting plate 31 and is fixedly connected to the fixed plate 35. It should be noted that in the initial state, the first spring 34 is compressed, so that the elastic force of the first spring 34 can reduce the distance between the lifting plate 31 and the fixed plate 35 during the descent.

[0029] In this embodiment, Figures 2 to 5 As shown, the reciprocating assembly 38 includes a long plate 39 fixedly connected to the bottom of the lifting plate 31. One side of the long plate 39 is slidably connected to the translation rod 310. A second spring 311 is sleeved on one side of the translation rod 310. The other side of the translation rod 310 passes through the long plate 39 and is connected to the C-shaped plate 312. One side of the C-shaped plate 312 is fixedly connected to an extrusion block 313, which cooperates with the groove 322. It should be noted that the bottom of the extrusion block 313 is provided with a first inclined surface, and the bottom of the groove 322 is provided with a second inclined surface that matches the first inclined surface. When the extrusion block 313 descends, it can squeeze the groove 322 to move the extrusion block 313.

[0030] Guide blocks 314 are connected to both sides of the C-shaped plate 312 , and the guide blocks 314 are slidably connected to the groove body of the guide groove 37 .

[0031] In this embodiment, Figure 4As shown, electric telescopic rods 315 are fixedly connected to both sides of the long plate 39, and the driving end of the electric telescopic rod 315 is connected to the C-shaped plate 312. It should be noted that the electric telescopic rod 315 can move the C-shaped plate 312 and the extrusion block 313 to facilitate the reset of the support 36 and the fixed plate 35.

[0032] In this embodiment, Figures 2 to 4 As shown, the guide groove 37 is composed of a serpentine groove 371 and a C-shaped groove 372. The outlet end of the serpentine groove 371 is connected to the inlet end of the C-shaped groove 372, and the outlet end of the C-shaped groove 372 is connected to the inlet end of the serpentine groove 371, forming a closed loop structure. It should be noted that the serpentine groove 371 is composed of multiple C-shaped grooves, and the width of the upper C-shaped groove is greater than the width of the lower C-shaped groove. Therefore, when the guide block 314 is located in different C-shaped grooves, the support 36 rises to different heights.

[0033] In this embodiment, Figures 4 and 5 As shown, the linear adjustment mechanism 316 includes a first telescopic member 317 fixedly connected to both sides of the bottom of the fixed plate 35, and a third spring 318 sleeved on the first telescopic member 317. The bottom of the first telescopic member 317 is connected to the first support plate 319, and one side of the bottom of the first support plate 319 is rotatably connected to the pressure roller 320. It should be noted that the pressure of the pressure roller 320 can be adjusted by compressing the third spring 318. When the thickness of the circuit board is between thick and the thickest, the first telescopic member 317 is fully retracted when squeezing the circuit board. When the first telescopic member 317 is fully retracted, the squeezing block 313 fits neatly into the groove 322.

[0034] Furthermore, the working principle of the rolling mechanism 3 is as follows: since the extension length of the driving end of the first cylinder 2 is fixed, when the pressure roller 320 contacts circuit boards of different thicknesses, the distance between the lifting plate 31 and the preset position is different. The first cylinder 2 drives the lifting plate 31, the nonlinear adjustment mechanism, the fixed plate 35, the linear adjustment mechanism 316, and the sliding plate 321 to descend. When the pressure roller 320 contacts the circuit board, the sliding plate 321 is fixed by the locking assembly. At this time, during the descent of the lifting plate 31, the third spring 318 is compressed, which can increase the pressure. When the first telescopic member 317 is fully retracted, the extrusion block 313 is precisely inserted into the groove 322. Then, the extrusion block 313 is lowered to a first set value, and the extrusion block 313 squeezes the groove 322 to move the extrusion block 313, the C-shaped plate 312 and the guide block 314. When the extrusion block 313 is out of the groove 322, the guide block 314 is located on one side of the C-shaped slide. At this time, the elastic force of the first spring 34 causes the lifting rod 33 and the fixed plate 35 to rise to a second set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31. After the extrusion block 313 is lowered to the first set value, the extrusion block 313 enters the groove 322, thereby moving the guide block 314 to the other side of the C-shaped slide. At this time, the elastic force of the first spring 34 causes the lifting rod 33 and the fixed plate 35 to rise to the second set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31. When the extrusion block 313 drops to the third set value, the extrusion groove 322 is squeezed to move the extrusion block 313. When the extrusion block 313 disengages from the groove 322, the guide block 314 is located on one side of the C-shaped slide. At this time, the elastic force of the first spring 34 causes the fixed plate 35 to rise to the fourth set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31. When the extrusion block 313 drops to the third set value, the extrusion block 313 enters the groove 322, thereby moving the guide block 314 to the other side of the C-shaped slide. At this time, the elastic force of the first spring 34 causes the fixed plate 35 to rise to the fourth set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31.

[0035] In this embodiment, Figures 5 to 8 As shown, the speed change mechanism 4 includes an arm 41 rotatably connected to one side of the lifting plate 31, a synchronous telescopic assembly is connected to the bottom of the arm 41, a rotating motor 44 is connected to one side of the bottom of the synchronous telescopic assembly, and the driving end of the rotating motor 44 passes through the synchronous telescopic assembly to connect to the driving wheel 45.

[0036] One end of the pressure roller 320 passes through the first support plate 319 and is connected to the first conical wheel 47 . The first conical wheel 47 cooperates with the driving wheel 45 .

[0037] One side of the first support plate 319 is rotatably connected to the second conical wheel 48 , and the second conical wheel 48 cooperates with the driving wheel 45 .

[0038] A first guide rod 46 and a second guide rod 49 are fixedly connected to one side of the first support plate 319. The first guide rod 46 and the second guide rod 49 are slidably connected to the synchronous telescopic assembly. It should be noted that a fixed housing 410 on one side of the first support plate 319 is fixedly connected to the first guide rod 46 and the second guide rod 49. The first conical wheel 47 and the second conical wheel 48 are rotatably connected to the fixed housing 410. The first conical wheel 47 and the second conical wheel 48 are arranged in opposite directions, so that the small diameter end of the first conical wheel 47 and the large diameter end of the second conical wheel 48 are located on the same side. When the driving wheel 45 rotates, the first and second conical wheels 47 and 48 can rotate simultaneously, but the rotation speeds of the first and second conical wheels 47 and 48 are inversely proportional.

[0039] In this embodiment, Figure 5 、 Figure 7 and Figure 8 As shown, the synchronous telescopic assembly includes a vertical rod 42 rotatably connected to the bottom of the arm 41 , and a through hole is provided at the bottom of the vertical rod 42 , which is slidably connected to the second guide rod 49 .

[0040] A third telescopic member 43 is fixedly connected to one side of the bottom of the vertical rod 42, and the third telescopic member 43 is fixedly connected to the rotating motor 44. The bottom of the third telescopic member 43 is provided with a square hole, and the hole body of the square hole is slidably connected to the first guide rod 46. It should be noted that the top of the fixed shell 410 is provided with a rectangular hole, and the hole body of the rectangular hole is slidably connected to the vertical rod 42.

[0041] Furthermore, the working principle of the speed change mechanism 4 is as follows: since the distance between the fixed plate 35 and the lifting plate 31 is reduced, the arm 41 can be rotated, thereby moving the vertical rod 42 and the third telescopic member 43. Due to the restrictions of the first guide rod 46 and the second guide rod 49, the driving wheel 45 can be moved between the first conical wheel 47 and the second conical wheel 48, thereby controlling the transmission ratio and adjusting the speed according to the thickness of the circuit board. The driving wheel 45 is driven to rotate by the rotating motor 44, so that the first conical wheel 47 and the second conical wheel 48 can rotate at the same time, but the rotation speed of the first conical wheel 47 and the second conical wheel 48 are inversely proportional. The pressure roller 320 is rotated by the first conical wheel 47 to realize the rolling of the circuit board.

[0042] In this embodiment, Figure 5 、 Figure 6 and Figure 8As shown, the feeding mechanism 5 includes a second cylinder 51 fixedly connected to the top of the first support plate 319 on the side away from the first telescopic member 317. The driving end of the second cylinder 51 passes through the first support plate 319 and is connected to the second support plate 52. The bottom of the second support plate 52 is rotatably connected to the feed roller 53. One side of the feed roller 53 is connected to a transmission assembly, which is connected to the second conical wheel 48. It should be noted that the friction force of the feed roller 53 is greater than the sum of the resistance of the pressure roller 320 and the inertia of the circuit board, thereby preventing relative sliding between the feed roller 53 and the circuit board during transportation. The position of the feed roller 53 can be adjusted by the second cylinder 51 so that the feed roller 53 can contact the circuit board alone and transport the circuit board.

[0043] In this embodiment, Figure 5 、 Figure 6 and Figure 8 As shown, the transmission assembly includes a first pulley 54 connected to one side of the feed roller 53.

[0044] One side of the first support plate 319 is connected to the tensioning assembly 57, and the tensioning assembly 57 includes a fourth telescopic member 571 connected to one side of the first support plate 319 and a fifth spring 572 sleeved on the fourth telescopic member 571. The bottom of the fourth telescopic member 571 is connected to the sliding block 573, and one side of the sliding block 573 is rotatably connected to the tensioning wheel 574.

[0045] One end of the second conical pulley 48 passes through the fixed housing 410 and connects to the second pulley 55. The outer walls of the second pulley 55, the first pulley 54, and the tensioning pulley 574 are adapted to connect to the synchronous belt 56, forming a closed transmission loop around the three. It should be noted that the transmission assembly enables the second conical pulley 48 and the feed roller 53 to rotate synchronously.

[0046] Furthermore, the working principle of the feeding mechanism 5 is as follows: the second pulley 55 is rotated through the second conical wheel 48, and the second pulley 55, the first pulley 54 and the tensioning wheel 574 are rotated synchronously through the synchronous belt 56, thereby driving the feeding roller 53 to rotate.

[0047] In this embodiment, Figures 1 to 8 As shown, a method for using a circuit board rolling device for manufacturing integrated optoelectronic devices includes the following steps: S1: During the manufacturing process of the integrated optoelectronic device, the circuit board is first placed on the base plate 12, and then the circuit board is fixed by a fixing device.

[0048] S2: The lifting plate 31, the nonlinear adjustment mechanism, the fixed plate 35, the linear adjustment mechanism 316 and the sliding plate 321 are driven downward by the first cylinder 2. When the pressure roller 320 contacts the circuit board, the sliding plate 321 is fixed by the locking assembly.

[0049] S3: When the thickness of the circuit board is in the thinnest range, the third spring 318 is compressed by descending the lifting plate 31, which can increase the pressure. At this time, the distance between the fixed plate 35 and the lifting plate 31 gradually decreases, so the arm 41 can be rotated, thereby moving the vertical rod 42 and the third telescopic member 43, and then the driving wheel 45 is moved between the first conical wheel 47 and the second conical wheel 48. Then, the driving wheel 45 is driven to rotate by the rotating motor 44, so that the first conical wheel 47 and the second conical wheel 48 can rotate at the same time, and the pressure roller 320 is rotated by the first conical wheel 47, and the second conical wheel 48 and the feed roller 53 are rotated synchronously by the transmission assembly, thereby realizing the control of the rolling speed and the feed amount of the circuit board.

[0050] When the first retractable member 317 is fully retracted, the extrusion block 313 is inserted into the groove 322. At this time, the guide block 314 is located on one side of the C-shaped slot. The elastic force of the first spring 34 causes the lifting rod 33 and the fixed plate 35 to rise by a second set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31. Subsequently, the extrusion block 313 is lowered by the first set value. The extrusion block 313 squeezes the groove 322 to move the extrusion block 313 and the guide block 314. When the extrusion block 313 is out of the groove 322, the guide block 314 is located on the other side of the C-shaped slot. At this time, the elastic force of the first spring 34 causes the lifting rod 33 and the fixed plate 35 to rise by the second set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31.

[0051] S5: When the thickness of the circuit board is in the thickest range, repeat the operation of S4. When the guide block 314 moves out of the C-shaped slide groove of the second set value, the extrusion block 313 drops to the third set value and then squeezes the groove 322 to move the extrusion block 313. When the extrusion block 313 is out of the groove 322, the guide block 314 is located on one side of the C-shaped slide groove. At this time, the elastic force of the first spring 34 causes the fixed plate 35 to rise to the fourth set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31. When the extrusion block 313 drops to the third set value, the extrusion block 313 enters the groove 322, thereby causing the guide block 314 to move to the other side of the C-shaped slide groove. At this time, the elastic force of the first spring 34 causes the fixed plate 35 to rise to the fourth set value, thereby reducing the distance between the fixed plate 35 and the lifting plate 31, thereby realizing multiple adjustments to the rotation speed of the pressure roller 320 and the feed roller 53.

[0052] S6: During resetting, the restriction of the sliding plate 321 is cancelled, and then the guide block 314 is located at the bottom of the guide groove. The C-shaped plate 312 and the extrusion block 313 can be moved by the electric telescopic rod 315, so that the guide block 314 is located in the C-shaped groove. Then, the lifting plate 31 is driven to rise by the first cylinder 2. When the top end of the lifting rod 33 contacts the C-shaped frame 11, the position of the lifting rod 33 can be restricted. At this time, the lifting plate 31 continues to rise, and relative sliding can occur between the lifting plate 31 and the lifting rod 33, thereby realizing the resetting of the support 36 and the fixed plate 35.
