Description

Technical Field

[0001] The present invention relates to an LED mounter, and more particularly to an intelligent two-way mounter. Background Art

[0002] The mounter for LED chip mounting uses a mounting head to mount LED lamp chips on an integrated LED lamp board, realizing an automated high-speed mounting process for LED chip mounting. The fully automatic LED mounter, which is the most critical and complex equipment in SMT production, realizes the high-speed and high-precision fully automatic production process of LED light strips. Existing LED mounters generally use the reciprocating motion of a single mounting head to suck and mount LED chips, which is very time-consuming during the movement from sucking to mounting. In order to improve the mounting efficiency, there has also appeared a double-headed mounter on the market that uses two side-by-side two-way mounting heads to simultaneously mount a single mounting board. However, the double-headed mounter with side-by-side synchronous drive cannot achieve flexible mounting of different mounting boards, and it is also difficult to further improve the mounting efficiency. Summary of the Invention

A conveyor belt wheel for driving the movement of the material plate is further provided on the Y-axis conveying frame. The Y-axis conveying seat is slidably arranged on the Y-axis support seat along the Y-axis direction.

[0008] As a further improvement of the above technical solution, there are two Y-axis conveying frames, one is provided on each side of the Y-axis conveying seat. The Y-axis conveying frame is slidably arranged on the Y-axis conveying seat through a Y-axis driving device. A jacking device for jacking up the top plate is provided at the bottom of the top plate.

[0010] As a further improvement of the above technical solution, the Y-axis driving device is arranged on the side of the fixed Y-axis conveying frame and includes a driving motor fixed on the side, a driving belt pulley set, and a driving lead screw. One driving lead screw is provided at each of the two ends of the two Y-axis conveying frames. The driving lead screw is driven by the driving motor and the driving belt pulley set to rotate synchronously.

[0011] As a further improvement of the above technical solution, the housing is arranged outside the mounter. An inlet, a plate inlet, a conveying detection port, a mounting detection port are further provided on the housing, and a mounting detection cover and a conveying detection cover are rotatably arranged outside the conveying detection port and the mounting detection port.

[0037] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present invention in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be interactively combined without conflicting with each other.

[0038] Refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , an intelligent two-way mounter, comprising a housing 4, a base 5, a support cross beam 6, a mounting head 7, a loading feeder 8 for feeding the mounting head 7, and a board feeding mechanism for conveying the mounting board. The mounting head 7 is slidably arranged on the support cross beam 6 through a linear motor 9. There are two loading feeders 8, mounting heads 7 and support cross beams 6, and they are symmetrically arranged on both sides in the X-axis direction of the base 5. The two mounting heads 7 are respectively supported by two support cross beams 6, and the two linear motors 9 drive without interference and operate independently. The process of sucking and transporting the chips is more flexible and efficient, and they are symmetrically arranged on the base 5, and feeding is carried out on both sides of the mounter respectively, which is equivalent to two different mounters, ensuring the independence during chip mounting. The board feeding mechanism includes an X-axis transportation device 1 and a Y-axis board feeding device 2. The X-axis transportation device 1 is located in the middle of the two support cross beams 6, and the Y-axis board feeding device 2 is vertically arranged at the ends of the two support cross beams 6 and perpendicular to the two support cross beams 6.

[0039] Refer to Figure 6 , Figure 7 , Figure 8, when it is necessary to feed the board to the mounter on the left, adjust the X-axis transport device 1 to make the X-axis transport device 1 close to the left support crossbeam 6. At the same time, adjust the position of the Y-axis board feeding device 2 so that it aligns with the X-axis transport device 1. After the adjustment, the X-axis transport device 1 transports the mounting board to the Y-axis board feeding device 2, and the Y-axis board feeding device 2 then transports the mounting board to the mounting position of the left mounter for mounting. The X-axis transport device 1 provided in the middle of the two symmetrical support crossbeams 6 can simultaneously transport the feeder boards to the mounting heads 7 located on the two support crossbeams 6. Cooperating with the relatively vertically arranged Y-axis board feeding device 2, it realizes the movement process of the board feeding mechanism feeding the boards to the two mounting heads 7 simultaneously, and cross-transports the mounting boards to the two mounting heads 7 from the X-axis and Y-axis directions respectively, making the mounting process more flexible and diverse while ensuring the conveying efficiency of the mounting board and the mounting efficiency of the mounter.

[0040] Refer to Figure 7 , Figure 9 , Figure 10 , the X-axis transport device 1 includes an X-axis support base 11, an X-axis conveyor frame 12, X-axis slide rails 13, an X-axis drive mechanism for driving the X-axis conveyor frame 12, and an X-axis adjustment mechanism 14 for adjusting the X-axis conveyor frame 12. The X-axis conveyor frame 12 is also provided with conveyor belt wheels for transporting the mounting board. The two adjustable X-axis conveyor frames 12 can change the width of the board feeding mechanism, enabling the board feeding mechanism to adapt to mounting boards of different models and sizes, maintaining the stability and diversity of the conveying process, and increasing the mounting range of the mounter.

[0041] The X-axis conveyor frame 12 is slidably arranged on the X-axis support base 11 through the X-axis slide rails 13. Both the X-axis conveyor frame 12 and the X-axis slide rails 13 are provided with two. The two X-axis slide rails 13 are arranged in parallel on both sides of the X-axis support base 11, and the two X-axis conveyor frames 12 are perpendicular to the X-axis slide rails 13. The X-axis slide rails 13 can not only support and slide the X-axis conveyor frame 12, but also fix the sliding direction of the X-axis conveyor frame 12, enabling the X-axis conveyor frame 12 to slide at the position required by the mounter, increasing the diversity of the conveying process, as well as the applicable situation and scope of the conveying device.

[0042] Refer to Figure 7 , Figure 11, the Y-axis board feeding device 2 includes a top plate 21, a Y-axis support base 22, a Y-axis conveying base 23, and a Y-axis conveying frame 24 located on the Y-axis conveying base 23. A conveyor belt wheel for driving the movement of the board is further provided on the Y-axis conveying frame 24. The Y-axis conveying base 23 is slidably arranged on the Y-axis support base 22 in the Y-axis direction. A jacking device 3 for jacking up the top plate 21 is provided at the bottom of the top plate 21. The top plate 21 is driven by a jacking assembly arranged between the Y-axis conveying base 23 and the top plate 21 relative to direct jacking by a cylinder, making the rising process of the mounting board more stable, balanced, with a fixed rising height, small rising error, high mechanical efficiency, and thus higher production efficiency of the mounter.

[0043] The Y-axis driving device 25 is arranged on the side of the fixed Y-axis conveying frame 24, and includes a driving motor fixed on the side, a driving pulley set, and a driving lead screw. One driving lead screw is provided at each of the two ends of the two Y-axis conveying frames 24. The driving lead screw is driven to rotate synchronously by the driving motor and the driving pulley set. The two Y-axis conveying frames 24 are respectively arranged on both sides of the Y-axis conveying base 23. One is slidably arranged on the Y-axis conveying base 23 through the driving lead screw, and one Y-axis conveying frame 24 is fixed on one side of the Y-axis conveying base 23. Two driving lead screws are provided, and are respectively connected to the two ends of the sliding Y-axis conveying frame 24. When encountering a mounting board with a smaller width, the driving motor is started. The driving motor drives the pulley set to rotate, thereby driving the two driving lead screws to rotate synchronously, and then driving the slidably arranged Y-axis conveying frame 24 to move towards the direction of the fixed Y-axis conveying frame 24, thereby reducing the distance between the two-axis conveying frames, enabling the board feeding device to adapt to mounting boards of different sizes, and improving the applicable range of the mounter.

[0044] There are two Y-axis conveying frames 24, and one Y-axis conveying frame 24 is provided on each side of the Y-axis conveying base 23. One of the Y-axis conveying frames 24 is slidably arranged on the Y-axis conveying base 23 through a driving device, and one Y-axis conveying frame 24 is fixed on one side of the Y-axis conveying base 23. When encountering a mounting board with a smaller width, the Y-axis driving device 25 is started. The Y-axis driving device 25 drives the other Y-axis conveying frame 24 to move towards the direction of the fixed Y-axis conveying frame 24, thereby reducing the distance between the two Y-axis conveying frames 24, enabling the board feeding device to adapt to mounting boards of different sizes, and improving the applicable range of the mounter. A conveyor belt wheel for driving the movement of the board is further provided on the Y-axis conveying frame 24. The mounting board contacts the conveyor belt wheel and is conveyed to or from the board feeding device to the mounting position through the conveyor belt wheel. The conveyor belt wheels corresponding to the two Y-axis conveying frames 24 on both sides are more balanced and stable, more flexible, and have better conveying effect during the conveying process.

[0045] Refer to Figure 12, the lifting device 3 includes a lifting part 31, a driving part 32 and a connecting part 33. The top plate 21 is fixed on the lifting part 31 and is lifted by the lifting part 31. One set of the lifting parts 31 is provided on each side of the Y-axis conveying seat 23. The two sets of lifting parts 31 are connected by the connecting part 33 and are driven by the driving part 32 to operate synchronously. When the driving part 32 drives the lifting part 31 on one side to move, it drives the connecting part 33 to move, thereby driving the lifting part 31 on the other side to move synchronously, and then lifting and lowering the top plate 21 from both sides, so that the top plate 21 remains balanced and stable during the lifting process.

[0046] Refer to Figure 1 , Figure 2 , the housing 4 is arranged outside the mounter. The housing 4 is also provided with a feeding port 41, a board feeding port 42, a conveying detection port 43 and a mounting detection port 44, as well as a mounting detection cover 45 and a conveying detection cover 46 rotatably arranged outside the conveying detection port 43 and the mounting detection port 44. The feeding port 41 corresponds to the position of the loading feeder 8, facilitating the LED patch light strip to enter the loading feeder 8 through the feeding port 41. The board feeding port 42 is located at the corresponding position of the end of the X-axis conveying device 1 on the housing 4. The mounting board enters the housing 4 through the board feeding port 42 and is transmitted through the X-axis conveying device 1.

[0047] There are two feeding ports 41, mounting detection ports 44 and conveying detection ports 43, and they are symmetrically arranged on both sides of the housing 4 corresponding to the Y-axis board feeding device 2 and the support cross beam 6. The two sets of feeding ports 41 and detection ports symmetrically arranged on both sides can respectively detect the mounting components on both sides, with a wider detection range and higher efficiency. The feeding port 41 is arranged at the corresponding position of the feeder feeding device on the machine housing body. The mounting detection port 44 and the conveying detection port 43 can detect the mounting process and the conveying process of the mounter at the mounting position and the conveying position of the mounting head 7 of the mounter. When the mounter malfunctions or encounters problems during the conveying process or the mounting process, the main mounting and conveying components of the machine can be inspected and repaired through the mounting detection port 44 and the conveying detection port 43, greatly facilitating the maintenance and arrangement process of the mounter and ensuring the mounting accuracy and service life of the mounter.

[0048] Refer to Figure 2 , Figure 3 , the base 5 is also provided with adjusting legs 51. The adjusting legs 51 fixedly support the mounter at the bottom of the base 5. There are multiple adjusting legs 51 corresponding to the support points of the base 5, and they are all adjustable at the bottom of the mounter. The base 5 of the mounter has an irregular shape while supporting each component on the mounter. The irregular shape has a smaller volume, reducing the space occupancy rate and production cost. Therefore, the adjusting legs 51 are evenly arranged on the support points of the base 5 based on the force on each edge when supporting the base 5.

[0049] The above is a specific description of the preferred embodiment of the present invention. However, the present invention is not limited to the described embodiments.
