Description

Technical Field

[0001] This utility model relates to the field of LED chip mounter technology, specifically to a six-arm chip mounter. Background Technology

[0002] LED pick-and-place machines are the main equipment in SMT production lines. Also known as LED surface mount systems or LED mounting machines, they use a control system to drive the placement head to move, pick up LED chips from the feed point through the nozzle, and accurately place the LED chips on the PCB fixture board to complete the placement.

[0003] Existing LED chip mounters have the following problems:

[0004] 1. The placement head of the pick-and-place machine may have unnecessary idle strokes during its movement, which will increase the placement time.

[0005] 2. The LED chip feeder is not positioned properly, which causes the placement head to have to move a long distance frequently to pick up the chips.

[0006] 3. The PCB fixture board is fed by belt conveyor, which is slow. Utility Model Content

[0007] To overcome the shortcomings of the existing technology, this utility model provides a six-arm placement machine, which uses a placement head with a six-arm structure to perform placement in a rotating manner, thereby reducing the stroke and improving placement efficiency.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A six-arm placement machine includes a frame, an LED feeding mechanism for providing LED chips, a PCB feeding mechanism for providing a PCB fixture board, a placement platform for supporting the PCB fixture board, a shaping mechanism for shaping and positioning the LED chips, and a six-arm placement head for placement. The six-arm placement head is mounted on the frame via a bracket and includes a swing arm base, six swing arms connected to the swing arm base and arranged in a circular array, and a first driving member for driving the swing arm base to rotate. The ends of the swing arms are provided with working parts, which are used to pick up and place LED chips. When the swing arm base rotates, the working parts pass through the LED feeding mechanism, the shaping mechanism, and the placement platform.

[0010] As a further improvement to the above technical solution, the six-arm mounting head includes an arm base plate, which is connected to the frame via a gantry frame. A rotating spindle seat is provided on the arm base plate. The first driving component includes a motor, which is mounted on the arm base plate via a motor support frame. The motor spindle is connected to the rotating spindle seat, and the arm base is connected to the end of the motor spindle.

[0011] As a further improvement to the above technical solution, the six-arm mounting head also includes a sliding assembly. All six arms are slidably connected to the arm base via a sliding assembly. Two side-top mechanisms are provided on the arm base plate. The two side-top mechanisms are used to drive the arms located above the LED feeding mechanism and the mounting platform to move up and down.

[0012] As a further improvement to the above technical solution, the mounting platform includes a stage and a cross-shaped linear module that drives the stage to move along the XY direction. The stage includes a base plate and two trays that are disposed opposite to each other on the base plate. Both trays are provided with steps, and the steps of the two trays form positioning grooves for placing PCB fixture boards.

[0013] As a further improvement to the above technical solution, the mounting platform also includes a clamping assembly, which includes a clamping buckle and a second driving assembly. The clamping buckle is slidably connected to the support plate, and the second driving assembly is used to drive the clamping buckle to move up and down. When the clamping buckle moves down, it is used to press the PCB fixture board onto the step.

[0014] As a further improvement to the above technical solution, the PCB feeding mechanism includes a transfer mechanism, a first connecting mechanism, and a second connecting mechanism. There is a connecting position between the first connecting mechanism and the second connecting mechanism. The cross-shaped linear module can drive the platform to move to the connecting position and dock with the first connecting mechanism or the second connecting mechanism. When the platform docks with the first connecting mechanism, the transfer mechanism is used to drive the PCB fixture board from the first connecting mechanism to the platform. When the platform docks with the second connecting mechanism, the transfer mechanism is used to drive the PCB fixture board from the platform to the second connecting mechanism.

[0015] As a further improvement to the above technical solution, the transplanting mechanism includes a push plate, a third driving member, and a fourth driving member. The driving end of the fourth driving member is fixedly connected to two of the third driving members. The fourth driving member is used to drive the third driving members to move along the length direction of the first connecting mechanism. The driving end of the third driving member is fixedly connected to the push plate. The third driving member is used to drive the push plate to move up and down.

[0016] As a further improvement to the above technical solution, the LED feeding mechanism includes a feeding trolley and a feeding feeder. The feeding trolley is used to provide LED beads to the feeding feeder, and the feeding feeder is used to transport the LED beads to the picking position. The working part on the swing arm picks up the LED beads at the picking position.

[0017] As a further improvement to the above technical solution, the six-arm placement machine also includes a detection component, which includes multiple cameras, each used to take pictures of the LED beads located at the material picking position, the clamping position, and the placement position.

[0018] As a further improvement to the above technical solution, the six-arm placement machine also includes an NG tube, which is used to store NG LED beads.

[0019] The beneficial effects of this utility model are: the six-arm placement head has six arms, and the multiple work positions of the placement (material picking position, clamping position, placement position, NG position) are located below one of the arms. In this way, when the placement is performed by the six-arm placement head in a rotating manner, the actions of multiple work positions can be performed simultaneously, reducing the stroke and improving the placement efficiency.

Detailed Implementation

[0029] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0030] Reference Figure 1-3This utility model provides a six-arm placement machine, including a frame 1, an LED feeding mechanism, a PCB feeding mechanism 7, a placement platform 6, a shaping mechanism 4, and a six-arm placement head 5. The six-arm placement head 5 is mounted on the frame 1 via a bracket and includes an arm base 55, six arms 56 connected to the arm base 55 and arranged in a circular array, and a first driving member for driving the arm base 55 to rotate. Each arm 56 has a working part 57 (using a vacuum nozzle structure) at its end, which is used to pick up and place LED beads. When the arm base 55 rotates, the working part 57 passes through... The LED assembly process involves an LED feeding mechanism, a shaping mechanism 4, and a placement platform 6. The LED feeding mechanism feeds LED chips to the pick-up position. A workpiece 57 on one of the swing arms 56 removes the LED chip from the pick-up position and moves to the clamping position. The shaping mechanism 4 clamps and shapes the LED chip at the clamping position to reduce deviations and errors during placement. Simultaneously, the next swing arm 56 moves to the pick-up position to pick up the LED chip. The swing arm base 55 continues to rotate, and the first swing arm 56 that picked up the LED chip moves to the placement position, placing the LED chip onto the PCB fixture board on the placement platform 6. It is understood that the swing arm base 55 rotates 60° each time, and the swing arms 56 move simultaneously to each station, greatly improving placement efficiency.

[0031] In this embodiment, refer to Figure 4 The six-arm mounting head 5 includes a swing arm base plate 52, which is connected to the frame 1 via a gantry frame 51, so that the six-arm mounting head 5 straddles the frame 1. A rotating spindle seat is provided on the swing arm base plate 52. The first driving component includes a motor 54, which is mounted on the swing arm base plate 52 via a motor support frame 53. The spindle of the motor 54 is connected to the rotating spindle seat, and the swing arm seat 55 is connected to the end of the spindle of the motor 54. Thus, the motor 54 can drive the swing arm seat 55 to rotate, thereby driving the swing arm 56 to rotate.

[0032] Furthermore, refer to Figure 4 The six-arm mounting head 5 also includes a sliding assembly. The sliding assembly adopts a linear guide rail structure (first linear guide rail 58). All six arms 56 are slidably connected to the arm base 55 in the vertical direction through a first linear guide rail 58. Two side-top mechanisms 59 are provided on the arm base plate 52. The two side-top mechanisms 59 are used to drive the arms 56 located above the LED feeding mechanism and the mounting platform 6 to move up and down (the side-top mechanisms 59 can be cylinders, linear modules, cam mechanisms, etc., that drive objects to make linear reciprocating motion). That is, when the arm 56 rotates to the picking position and the mounting position, the two side-top mechanisms 59 drive the arm 56 to move up and down, thereby realizing the picking and mounting actions.

[0033] In this embodiment, refer to Figure 5 and Figure 6 The placement platform 6 includes a carrier, a clamping assembly 64, and a cross-shaped linear module 65. The carrier includes a base plate 61 and two support plates 62 disposed opposite to each other on the base plate 61. Each of the two support plates 62 is provided with a step 63, which forms a positioning groove for placing the PCB fixture board. The clamping assembly 64 includes clamping buckles 641 and a second driving assembly. The clamping buckles 641 are slidably connected to the support plates 62 in the vertical direction via a second linear guide rail 643. The second driving assembly includes a first cylinder 644, the driving end of which is connected to a connecting plate 642. Multiple clamping buckles 641 are fixed on the connecting plate 642. The extension and retraction of the first cylinder 644 drives the multiple clamping buckles 641 to move up and down. When the clamping buckles 641 move downward, they press the PCB fixture board onto the step 63, thereby fixing the PCB fixture board during the placement process.

[0034] It is understood that the cross-shaped linear module 65 can drive the stage to move along the X and Y axes, thereby adjusting the patch position.

[0035] In this embodiment, refer to Figure 7 The PCB feeding mechanism 7 includes a transfer mechanism 73, a first connecting mechanism 71, and a second connecting mechanism 72. The first connecting mechanism 71 and the second connecting mechanism 72 have a connecting position. The first connecting mechanism 71 and the second connecting mechanism 72 have identical structures, each including two opposing connecting tracks. These two connecting tracks also form positioning grooves for placing the PCB fixture board, and their dimensions are the same as the positioning grooves on the platform, facilitating the connection of the PCB fixture board. The cross-shaped linear module 65 can drive the platform to move to the connecting position to connect with the first connecting mechanism 71 or the second connecting mechanism 72. When the platform connects with the first connecting mechanism 71, the transfer mechanism 73 drives the PCB fixture board from the first connecting mechanism 71 onto the platform. When the platform connects with the second connecting mechanism 72, the transfer mechanism 73 drives the PCB fixture board from the platform onto the second connecting mechanism 72.

[0036] Furthermore, the transplanting mechanism 73 includes a push plate 736, a third driving member, and a fourth driving member. The third driving member includes a second cylinder 734, and the fourth driving member includes a base 731 and a belt conveyor 732 mounted on the base 731. A fixed seat 733 is fixed on the belt of the belt conveyor 732. Two second cylinders 734 (second cylinder 734A and second cylinder 734B) are fixedly connected to the fixed seat 733. Push plate arms 735 are fixedly connected to the driving ends of the two second cylinders 734. A push plate 736 (push plate 736A and push plate 736B) is connected to the end of the push plate arm 735. The extension directions of the push plate arms 735 connected to the two second cylinders 734 are opposite. Thus, when the belt conveyor 732 is running, it drives the fixed seat 733 to move, thereby driving the push plate 736 to move along the length direction of the first connecting mechanism 71 / second connecting mechanism 72.

[0037] Understandably, after the PCB fixture board is conveyed to the first connecting mechanism 71, the second cylinder 734A drives the push plate 736A to move downwards. The platform docks with the first connecting mechanism 71, and the belt conveyor 732 drives the push plate 736A to move towards the platform. The push plate 736A pushes the PCB fixture board to slide on the first connecting mechanism 71 and move onto the platform. The platform moves to the placement position to perform the placement operation. After placement is completed, the platform moves to dock with the second connecting mechanism 72. The second cylinder 734B drives the push plate 736B to move downwards, and the belt conveyor 732 drives the push plate 736B to move towards the second connecting mechanism 72. The push plate 736B pushes the PCB fixture board to slide on the platform and move onto the second connecting mechanism 72, and pushes the PCB fixture board out of the second connecting mechanism 72 to the transport line of the next station. In this way, by replacing the traditional belt conveyor with the first connecting mechanism 71 and the second connecting structure, the docking accuracy and loading efficiency are improved.

[0038] In some embodiments, the six-arm placement machine further includes a detection component, which includes multiple cameras that take pictures of the LED beads located at the pick-up position, the clamping position, and the placement position to ensure the quality of the placement.

[0039] In some embodiments, the six-arm pick and place machine further includes an NG tube 8, which is located below the NG position. When the detection component detects an NG LED, the workpiece 57 carrying the NG LED rotates to the NG position, releasing the NG LED and causing it to fall into the NG tube 8.

[0040] Some mechanisms in this embodiment, such as the feeding trolley 2, the feeding feeder 3, and the shaping mechanism 4, are existing technologies in the field of patch technology, and their specific structures will not be described in this utility model.

[0041] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
