Description

Technical Field

[0001] The invention belongs to the technical field of PCBA processing, and in particular relates to a rotary jacking device, a rotary jacking method and assembly board processing equipment. Background Art

[0002] Printed Circuit Board Assembly (PCBA) refers to the finished product or semi-finished product after the electronic components are soldered to the PCB through surface mounting technology (SMT) on the basis of the printed circuit board (PCB), or the entire production process is completed through the DIP plug-in process. PCBA is not only a support for electronic components, but also a provider of circuit connections. The assembly process of PCBA is usually divided into different sections, including SMT top surface processing, SMT bot surface processing, and dip section processing. Different sections will carry out production operations on different production lines, and the process of line change will involve the online and offline of products.

[0003] For example, after the product is produced on the SMT top production line, it needs to be taken off the line and transported to the SMT bot production line by an AGV or a man-pulled cart. During the process of taking the product off the line, the product needs to be taken out of the fixture and rotated horizontally or flipped over according to the direction of the production operation. Abnormalities often occur when the product is taken off the line because the server circuit board is too large, usually with an outer dimension of about 500mm, and is heavy. When the circuit board is taken out of the fixture and rotated manually, the circuit board will collide with the carrier during the operation, causing the components under the circuit board to be knocked off, posing a safety hazard.

[0034] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0035] Embodiment 1

[0036] The present embodiment provides a rotary lifting device, which is applied to the production line processing of a circuit board (PCB) or an assembly board (PCBA). The rotary lifting device can lift and rotate the circuit board or assembly board. The rotary lifting device is located at a station on the production line and can adaptably dock with different production stations before and after. The products applicable to the rotary lifting device of the present embodiment are not limited to circuit boards or assembly boards, but are also applicable to flat-plate structure products with larger areas. The present embodiment is described by taking the assembly board as an example.

[0037] like Figure 1-Figure 8 As shown, the rotary lifting device can cooperate with the conveyor line, so that the rotary lifting assembly can be adapted to different front and rear workstations, and the conveyor line can be used to realize the automatic transportation of the carrier.

[0038] The carrier includes a first carrier plate 1 and a second carrier plate 2 positioned on the top of the first carrier plate 1; a first groove 11 is provided on the top of the first carrier plate 1, the second carrier plate 2 is arranged inside the first groove 11, the circumference of the second carrier plate 2 is abutted against the circumferential groove wall of the first groove 11, the bottom surface of the second carrier plate 2 is movably abutted against the groove bottom of the first groove 11, and the circumferential inward sink of the second carrier plate 2 is arranged in the first groove 11.

[0039] A second groove 21 is disposed on the top of the second carrier plate 2 . The second groove 21 is sunken into the surface of the second carrier plate 2 . The groove wall of the second groove 21 is disposed along the circumference of the second carrier plate 2 .

[0040] The first carrier plate 1 can be a square plate or a rectangular plate, and the second carrier plate 2 can be a square plate, a rectangular plate or a circular plate. This embodiment is described by taking the first carrier plate 1 as a rectangular plate and the second carrier plate 2 as a rectangular plate as an example. The two sides of the bottom of the first carrier plate 1 are overlapped with the conveyor line respectively, and the conveyor line is supported at the two sides of the bottom of the first carrier plate 1. The second carrier plate 2 is used to carry the assembly plate, and the assembly plate is positioned in the second groove 21. The circumference of the assembly plate can be embedded in the second groove 21 or the first groove 11. It is understood that the size of the assembly plate can be consistent with the second groove 21, and can also be consistent with the first groove 11. The second groove 21 can limit the assembly plate. Similarly, when the size of the assembly plate is larger than the second groove 21, the first groove 11 can limit the assembly plate, so that the assembly plate is stably positioned in the space formed by the second carrier plate 2 and the first carrier plate 1.

[0041] The first carrier plate 1 is provided with a limiting opening 12 at both ends, specifically, a group of limiting openings 12 are symmetrically provided at both ends of the first carrier plate 1 along its horizontal center line, which means that a limiting opening 12 is provided at the front end of the moving direction of the first carrier plate 1, and another limiting opening 12 is provided at the rear end of the moving direction of the first carrier plate 1. The limiting opening 12 is an open structure, which can be a rectangular opening or a trapezoidal opening. In this embodiment, the limiting opening 12 is a trapezoidal opening. The first carrier plate 1 cooperates with the rotating lifting device through the limiting opening 12 to play the role of positioning the first carrier plate 1.

[0042] The first groove 11 is penetrated by a through-hole 13 and a plurality of first positioning holes 14, and the through-hole 13 is located at the approximate center of the first groove 11. The through-hole 13 is a hole that penetrates the first groove 11, and a group of first positioning holes 14 are arranged at the approximate diagonal positions of the first groove 11 on both sides of the through-hole 13, and the first positioning holes 14 are used to cooperate with the rotary jacking device to play a supporting and limiting role. The through-hole 13 can be a circular hole, a square hole or a special-shaped hole. In this embodiment, the through-hole 13 is a circular hole, and the through-hole 13 is used to cooperate with the rotary jacking device to play an avoidance role.

[0043] The second groove 21 is provided with a plurality of second positioning holes 22, which are arranged corresponding to the through-port 13, are in a vertical direction with the through-port 13, and are located directly above the through-port 13; the second positioning holes 22 are used to cooperate with the rotary lifting device to play a supporting and limiting role. When the bottom of the second carrier plate 2 is subjected to a lifting force, the second carrier plate 2 is separated from the first carrier plate 1, and the first carrier plate 1 is positioned by cooperating with the rotary lifting device through the plurality of first positioning holes 14, and the second carrier plate 2 is positioned by cooperating with the rotary lifting device through the plurality of second positioning holes 22. After the second carrier plate 2 is separated from the first carrier plate 1, it can be stably rotated and lifted, and the second carrier plate 2 can be accurately reset when it falls back to the first groove 11 of the first carrier plate 1 again, so as to realize the precise positioning of the assembly plate carried on the second carrier plate 2. The rotary lifting device does not directly contact the assembly plate. The rotary lifting device lifts and rotates the assembly plate through the second carrier plate 2. On the one hand, it avoids the rotary lifting device directly contacting the assembly plate and causing damage. On the other hand, the rotary lifting device contacts the first carrier plate 1 and the second carrier plate 2 respectively, so that the second carrier plate 2 can be separated from the first carrier plate 1 for lifting and rotation. The second carrier plate 2 can also fall back and reset into the first carrier plate 1 again, ensuring the position accuracy of the assembly plate in the carrier.

[0044] There is usually a gap when the existing products are directly positioned in the carrier, and there will be a certain amount of offset in the carrier. If the product is directly lifted, rotated, or lowered, it may be impossible to put the product back into the carrier. The above-mentioned carrier is provided with a first carrier plate 1 and a second carrier plate 2, and the design structure of the first groove 11 and the second groove 21 can effectively avoid the problems existing in the existing structure, and the product can be accurately reset in the carrier after being separated from the carrier.

[0045] This embodiment provides a rotary lifting device, including a lifting assembly 3 that is driven to be lifted and lowered, and a supporting assembly 4 that is driven to be rotated and lifted and lowered;

[0046] The lifting assembly 3 and the supporting assembly 4 have the same lifting direction, and the lifting assembly 3 avoids the circumference of the supporting assembly 4. The supporting assembly 4 includes a fixed sleeve 41, a rotating sleeve 42 disposed inside the fixed sleeve 41 and coaxially connected thereto, a lifting shaft 43 penetrating inside the rotating sleeve 42, and a supporting member 44 disposed at the end of the lifting shaft 43; the lifting shaft 43 is synchronously rotated with the rotating sleeve 42, and the lifting shaft 43 is axially movable along the rotating sleeve 42. The lifting assembly 3 can realize the lifting function, and the supporting assembly 4 can realize the lifting and rotating functions, and the two do not interfere with each other.

[0047] The lifting assembly 3 provided in this embodiment includes a lifting plate 31 and a fixed plate 32. The lifting plate 31 is adjustable relative to the fixed plate 32. The lifting plate 31 is provided with an escape opening 311. The support member 44 passes through the escape opening 311. The inner wall of the escape opening 311 does not contact the support member 44. The escape opening 311 is provided corresponding to the through opening 13 in the first carrier plate 1. The escape opening 311 may be completely aligned and overlapped with the through opening 13, or may not overlap. It is understood that the support member 44 can pass through the escape opening 311 and accurately enter the through opening 13 when driven to rise and fall.

[0048] The lifting assembly 3 and the supporting assembly 4 both move up and down in the vertical direction, so as to separate the second carrier plate 2 from the first carrier plate 1 of the carrier. A plurality of first positioning pins 33 are arranged on the top of the lifting plate 31, which are used to cooperate with the first positioning holes 14 in the carrier for positioning; a plurality of second positioning pins 45 are arranged on the top of the supporting member 44, which are used to cooperate with the second positioning holes 22 in the carrier for positioning. The lifting plate 31 of the specific lifting assembly 3 is driven to rise and fall, and the lifting plate 31 acts on the bottom of the first carrier plate 1 to support the first carrier plate 1. At the same time, the first positioning pin 33 is plugged into the first positioning hole 14, and the first carrier plate 1 does not undergo lifting deflection; the support assembly 4 is driven to rise and fall, and the support member 44 passes through the avoidance opening 311 and the through opening 13 in the first carrier plate 1. The support member 44 abuts against the bottom of the second carrier plate 2 to support the second carrier plate 2. At the same time, the second positioning pin 45 is plugged into the second positioning hole 22. As the support member 44 rises, the second carrier plate 2 is driven to separate from the first carrier plate 1, and the support member 44 is driven to rotate, thereby driving the second carrier plate 2 to rotate; when the support member 44 is reset, it drives the second carrier plate 2 to fall back into the first carrier plate 1, and the second carrier plate 2 can be accurately embedded in the first carrier plate 1 again, ensuring the stability and accuracy of the reset of the second carrier plate 2.

[0049] In another embodiment, a plurality of avoidance openings 311 may be provided on the lifting plate 31, and correspondingly, a plurality of support assemblies 4 may be provided on the rotating lifting device, and the support members 44 of the support assemblies 4 correspond to the avoidance openings 311. When the carrier does not need to be rotated, the plurality of support assemblies 4 only serve the lifting and lowering functions. According to different application scenarios and the sizes of different products to be positioned, the number of support assemblies 4 and the spatial positions of the support assemblies 4 can be reasonably designed.

[0050] In this embodiment, the support assembly 4 cooperates with the lifting assembly 3 to realize the separation of the second carrier 2 and the first carrier 1 in the carrier. The second carrier 2 can be lifted and rotated independently relative to the first carrier 1 to meet the steering requirements of the product on the second carrier 2 for processing. The second carrier 2 is driven by the lifting and rotation of the support assembly 4 and can be reset to the first carrier 1 again, ensuring the accuracy of the reset of the second carrier 2 and the first carrier 1, and improving the positioning accuracy of the product on the carrier during the production process; the support assembly 4 includes a lifting shaft 43 that runs through the interior of the rotating sleeve 42 and a support member 44 that is arranged at the end of the lifting shaft 43. The lifting shaft 43 is located in the rotating sleeve 42. The lifting shaft 43 is driven to lift and slide along the rotating sleeve 42 in a relatively stable manner, so that the support member 44 has a large load-bearing capacity. The support member 44 supports the carrier to achieve stable and smooth lifting and rotation movements, thereby improving the stability of the overall rotating lifting device.

[0055] In this embodiment, the fixed plate 32 and the lifting plate 31 are both roughly rectangular plate structures, and the fixed plate 32 is relatively parallel to the lifting plate 31. A plurality of guide seats 36 are arranged on the top of the lifting plate 31, and a first positioning pin 33 is arranged on the top of the guide seat 36. The first positioning pin 33 adopts a truncated cone structure. When the first positioning pin 33 is plugged into the first positioning hole 14 of the first carrier plate 1, the first positioning pin 33 can accurately enter the first positioning hole 14 and guide the first positioning hole 14. The guide seat 36 abuts against the bottom of the first carrier plate 1. In this embodiment, the number of the plurality of guide seats 36 is four, and they are respectively arranged at the four peripheral corners of the lifting plate 31 to form a stable support effect. The guide seat 36 is detachably connected to the lifting plate 31, so that the first positioning pin 33 of the guide seat 36 can adapt to different hole positions on the carrier, thereby increasing the applicability of the lifting plate 31.

[0070] The side wall of the first position-limiting seat 51 is provided with a connection port 511 communicating with the inner cavity, one end of the sensor 53 is connected to the first position-limiting member 52, and the other end of the sensor 53 extends out of the connection port 511; the upper part of the side wall of the first position-limiting seat 51 near the connection port 511 is provided with a sensor 54, and in this embodiment, the connection port 511 is provided in the vertical direction and is consistent with the elastic floating direction of the first position-limiting member 52. The sensor 53 moves up and down in the connection port 511, and the position of the sensor 53 can be identified by the sensor 54, thereby determining the position state of the first position-limiting member 52. When the carrier is transported through the transmission line, the bottom of the carrier is pressed against the first limiter 52, and the weight of the carrier acts on the first limiter 52. The first limiter 52 is forced to sink into the inner cavity of the first limiter seat 51, and the sensor 53 is far away from the sensor 54. The sensor 54 cannot sense the position of the sensor 53 at this time; as the carrier continues to move forward until it is separated from the first limiter 52, the first limiter 52 automatically resets, and the first limiter 52 pushes out of the inner cavity of the first limiter seat 51. The sensor 53 approaches the sensor 54. The sensor 54 senses the position of the sensor 53 at this time and determines that the carrier has moved into place. As the first limiter 52 pushes out of the first limiter seat 51, the carrier is blocked, wherein the outer wall of the first limiter 52 abuts against the limit opening 12 of the carrier, and the carrier cannot move backward toward the rear of the transmission line.

[0071] The second limiting assembly 6 includes a second limiting seat 61, a fourth driving module 62 disposed on the second limiting seat 61, and a second limiting member 63 connected to the fourth driving module 62. The fourth driving module 62 can be an electric driving module, a hydraulic driving module or a pneumatic driving module. In this embodiment, the fourth driving module 62 is described as a pneumatic module. The fourth driving module 62 is a cylinder. The end of the second limiting member 63 is in rolling contact with the limiting opening 12, which is conducive to the rapid guidance and positioning of the second limiting member 63 and the carrier, and can also avoid hard contact and damage to the carrier; the second limiting member 63 is driven to rise and fall, and when the second limiting member 63 extends to the horizontal height of the carrier, the outer wall of the second limiting member 63 abuts against the limiting opening 12 of the carrier, and the carrier cannot continue to be transported toward the front of the conveyor line, and the carrier stops moving. Correspondingly, a space for positioning the carrier is formed between the first limiting member 52 and the second limiting member 63, and the lifting assembly 3 and the supporting assembly 4 can lift or rotate the carrier.

[0072] Since the carrier is transported and moved along the conveyor line, there may be position deviation when the carrier moves to the top of the rotary lifting device. In this embodiment, the limit opening 12 is a trapezoidal opening. When the first limit member 52 and / or the second limit member 63 abut against the limit opening 12, the trapezoidal opening structure of the limit opening 12 can guide the carrier to the position directly opposite the first limit member 52 and / or the second limit member 63, so that the carrier can be accurately positioned in the horizontal direction, that is, the position of the carrier along the X and Y directions is limited. The first positioning pin 33 of the lifting plate 31 cooperates with the carrier guide to limit the position of the carrier along the Z direction. The lifting height of the carrier by the lifting plate 31 can keep the carrier within the height range of the first limit member 52 and the second limit member 63. It is understood that the lifting plate 31 performs a lifting operation on the carrier without separating from the first limit member 52 and the second limit member 63, so as to keep the lifting process smooth and accurate.

Multiple rotating jacking devices can be arranged along the conveying direction of the conveyor line to meet the use requirements of the carriers at different workstations along the conveying direction.
