Specific embodiments
[0031] In order to make the invention objectives, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.
[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be intermediate components present.
[0033] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.
[0034] Please refer to Figures 1-4 , the embodiment of the present invention provides a flexible support device, including a mounting base plate 5, a support base 6, a support panel 1, a pressure detection device 2, a lifting device 3, a clamping device 4 and a control system.
[0035] The mounting base plate 5 is fixedly arranged in the support base 6. The mounting floor 5 and the support base 6 are mainly used as a support foundation.
[0036] The support panel 1 is arranged on the top surface of the support base 6. A first concave-convex group 13 is arranged on the support panel 1 corresponding to the positions of the non-precision components of the PCB. The shape of the first concave-convex group 13 matches the shape of the PCB and the non-precision components on the PCB to realize the support of the PCB.
[0037] The support panel 1 is provided with a through hole 11 corresponding to the precision components. The lifting device 3 is arranged below the support panel 1 and includes a lifting platform 31 and a power device 32 for driving the lifting platform 31 to move up and down; the pressure detection device 2 includes a pressure sensor 21 and a support block 22 fixedly arranged on the pressure sensor 21; the pressure sensor 21 is fixedly arranged on the lifting platform 31, and the support block 22 is correspondingly arranged in the through hole 11 and can reciprocate along the through hole 11; the control system is electrically connected to the power device 32 and the pressure sensor 21 respectively. In the present invention, the lifting height of the lifting platform 31 is controlled by the control system. When there is an error in the height of the components on the PCB, the control system controls the power device 32 to adjust the jacking power of the lifting platform 31, so that the supporting force of the support block 22 on the PCB is kept within the allowable range, avoiding the situation that the components on the PCB are damaged due to excessive pressure caused by the height error of the components.
[0038] The flexible support device further includes a clamping device 4; the clamping device 4 includes two clamping arms 41 and a driving device 42. The two clamping arms 41 are arranged at intervals and the lifting platform 31 is arranged between the two clamping arms 41. The driving device 42 is used to drive the two clamping arms 41 to move towards each other or away from each other; the control system is electrically connected to the driving device 42 and is used to control the two clamping arms 41 to perform the operation of clamping the lifting platform 31 when the pressure value received by the pressure sensor 21 is greater than the preset value. The clamping device 4 is used to clamp the lifting platform 31 so that the lifting platform 31 can be stably maintained at a suitable height. Specifically, after the lifting platform 31 rises to a suitable height, the two clamping arms 41 move towards each other under the drive of the driving device 42 to jointly clamp and position the platform.
[0039] Optionally, anti-slip patterns 311 are provided on both opposite side surfaces of the lifting platform 31, and anti-slip pads 411 are arranged on the side surfaces of the two clamping arms 41 for clamping the lifting platform 31 corresponding to the anti-slip patterns 311. Specifically, the two clamping arms 41 both move towards the direction close to the lifting platform, so that the anti-slip pads 411 on the clamping arms 41 abut against the side surfaces of the lifting platform 31 provided with the anti-slip patterns 311 to clamp the lifting platform 31.
[0040] Further, the driving device 42 is a parallel gripper. One clamping arm 41 is fixed on the left slider of the parallel gripper, and the other clamping arm 41 is fixed on the right slider of the parallel gripper; the lifting platform 31 is arranged between the left slider and the right slider. By arranging the clamping arms 41 on the existing parallel gripper, it is beneficial to reduce the production cost.
[0041] The control system includes a display screen. When the pressure value received by the pressure sensor 21 is greater than the warning value preset by the control system, a warning message will pop up on the display screen. When the pressure feedback by the pressure sensor 21 is greater than the preset warning value, the control system controls the two clamping arms 41 to release the lifting platform 31. The pressure from above the support panel 1 pushes the lifting platform downward, and the excessive pressure from above the support panel 1 is released. The pressure value received by the PCB board returns to within the allowable warning value. At this time, the pressure received by the PCB board is adjusted, and the situation of excessive pressure on the PCB board is improved to ensure the production yield of the PCB board. Specifically, the warning message can be set as: There is a risk of damaged products in the current setting. It is necessary to check the setting and see if the equipment is abnormal.
[0042] Ordinary components are provided on the PCB board; the support panel 1 is provided with a first convex-concave group 13 at the position corresponding to the ordinary components, and the support block 22 is provided with a second convex-concave group 221 at the position corresponding to the precision components on the PCB board. The first convex-concave group 13 and the second convex-concave group 221 provided on the support block 22 can not only make all positions of the PCB board be better supported, but also flexibly adjust the supporting force for the precision components, further avoiding damage to the precision components and improving the production yield of the PCB.
[0043] The power device 32 includes a first cylinder 321, and the lifting platform 31 is fixedly arranged at the top of the piston of the first cylinder 321.
[0044] The control system is used to control the first cylinder 321 to drive the support block 22 to support the precision components on the PCB board when the PCB board is placed on the support panel 1; after the PCB board is processed, the control system controls the first cylinder 321 to drive the support block 22 back to the initial position.
[0045] The first cylinder 321 is a double-rod cylinder. The double-rod cylinder can better maintain the stability of the lifting platform 31 during the lifting process, which is beneficial to improving the position accuracy of the support block 22.
[0046] The control system includes a storage device for recording the pressure received by the pressure sensor 21, and the storage device is electrically connected to the control system. The storage device is used to record the maximum pressure received by the precision components on each PCB board during the process, so as to find out in time whether it is the reason of the flexible support device when the device has problems, and is beneficial to improving the process and finding the most suitable supporting force for the precision components on the PCB board.
[0047] It should be known that a plurality of through holes 11 can be opened on the support panel 1, and a plurality of support blocks 22 are provided to realize flexible support for a plurality of precision components or a plurality of important positions on the PCB board.
[0048] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
