[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0057] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] This invention discloses a feeding device for a chip mounter, such as... Figure 1 and Figure 2 As shown, it includes: a conveying mechanism 1, a detection mechanism 2, a turning mechanism 3, a material handling mechanism 4, and a feeding mechanism 5. The detection mechanism 2, the turning mechanism 3, and the feeding mechanism 5 are arranged sequentially. The conveying mechanism 1 is used to convey the patch material to the detection mechanism 2. The detection mechanism 2 is used to detect the patch direction of the current patch material. The turning mechanism 3 is used to turn the patch material after it has been detected by the detection mechanism 2. The feeding mechanism 5 is used to receive the patch material transported by the material handling mechanism 4 and feed it in a straight line. The material handling mechanism 4 synchronously transports the patch material in the detection mechanism 2 and the turning mechanism 3 to transport the patch material in the detection mechanism 2 to the turning mechanism 3 and the patch material in the turning mechanism 3 to the feeding mechanism 5.

[0059] It should be noted that the material handling mechanism 4 synchronously transports the surface mount materials in the inspection mechanism 2 and the turning mechanism 3, transporting the surface mount materials in the inspection mechanism 2 to the turning mechanism 3, and then transporting the surface mount materials in the turning mechanism 3 to the feeding mechanism 5. This provides a feeding device for a surface mount machine, realizing the synchronous transport of surface mount materials between multiple workstations, improving its feeding rate, and thus improving the production efficiency of the surface mount machine.

[0060] like Figure 1 and Figure 2 As shown, it also includes: a first rejection mechanism 6, which is used to reject the patch waste detected by the detection mechanism 2 by blowing air.

[0061] like Figure 1 , Figure 2 and Figure 21 As shown, the first rejection mechanism 6 includes a first rejection pipe 61 with a first rejection channel 611. One end of the first rejection pipe 61 is provided with a first air blowing pipe 613 communicating with the first rejection pipe 61, and the first air blowing pipe 613 is used to provide compressed air. In specific implementation, the first rejection pipe 61 is fixedly installed on the detection mechanism 2 by a first rejection frame 62.

[0062] like Figure 1 , Figure 2 and Figure 21 As shown, a first notch 612 is provided on the first waste removal pipe 61. The first notch 612 is used to facilitate the material handling mechanism 4 to move the patch waste in the detection mechanism 2 to the air outlet of the first air blowing pipe 613.

[0063] like Figure 1 , Figure 2 , Figure 19 and Figure 20 As shown, it also includes a second rejection mechanism 7, which is used to reject the patch material that was not successfully fed on the feeding mechanism 5 by blowing air.

[0064] like Figure 1 , Figure 2 , Figure 19 and Figure 20As shown, the second rejection mechanism 7 includes a second rejection seat 71 with a second rejection channel 714. The second rejection seat 71 is equipped with a second air inlet 713 for blowing unsuccessfully fed patch material from the feeding mechanism 5 into the second rejection channel 714. The second air inlet 713 is used to introduce compressed air. In a specific implementation, the second rejection seat 71 has a second notch 711, a detachably connected second rejection cover 72, and a second rejection platform 73 at the bottom. The second rejection platform 73 has a discharge channel 731 communicating with the second rejection channel 714. The second rejection seat 71 also has a straightening groove 712 for straightening the patch material in the feeding trough 5311. The end opening of the straightening groove 712 is funnel-shaped.

[0065] It should be noted that the second notch 711 and the second waste removal cover 72 facilitate the observation and cleaning of the material jamming in the second waste removal channel 714, and the discharge channel 731 facilitates the orderly discharge of waste.

[0066] like Figure 19 and Figure 20 As shown, the second rejection seat 71 is equipped with a first detection optical fiber 74 for detecting patch materials that have not been successfully fed on the feeding mechanism 5.

[0067] like Figure 1-3 As shown, the material conveying mechanism 1 includes a vibratory feeder 11 and a linear feeder 12. The vibratory feeder 11 is used to receive several pieces of patch material and convey them to the linear feeder 12. The linear feeder 12 is provided with a feeding trough 121 for facilitating linear feeding of patch material.

[0068] like Figure 1 , Figure 2 and Figure 4-7As shown, the detection mechanism 2 includes a detection base 21 located at the discharge end of the conveying mechanism 1. A first detection light guide plate 22, a second detection light guide plate 23, and a detection cover plate 24 are sequentially installed on the top of the detection base 21. The second detection light guide plate 23 is provided with a second detection notch 231 for accommodating the material to be detected conveyed by the conveying mechanism 1. The detection camera 26 is located directly above the second detection notch 231. The detection cover plate 24 is provided with a cover plate notch 241 communicating with the second detection notch 231. Two backlights 25 are distributed on opposite sides of the detection base 21 to provide diffuse reflection light source to the material to be detected. The detection camera 26 is used to detect and identify the material orientation of the material to be detected on the first detection light guide plate 22. In the specific implementation process, the backlight 25 includes a backlight panel 251 and light-emitting beads 252. The backlight panel 251 is installed on the side wall of the detection base 21. The light-emitting beads 252 are diffuse reflection light sources. The horizontal height of the light-emitting beads 252 is flush with the top wall of the second detection light guide plate 23. The second detection notch 231 has a chamfered edge at one end near the linear feeder 12.

[0069] It should be noted that the material to be tested is transferred to the second detection notch 231 of the second detection light guide plate 23 by the feeding mechanism 1, the backlight 25 provides diffuse reflection light source to the material to be tested, and the detection camera 26 detects and identifies the material orientation of the material to be tested, so as to facilitate the detection of the material.

[0070] It should also be noted that when the surface mount material is in the linear feeding station, it needs to be fed linearly in the mounting direction, and then picked up and mounted by the robot arm of the surface mount machine. The surface mount material is an LED chip, and there is a notch on the surface mount material to identify the surface mount material. The backlight 25 provides a diffuse reflection light source so that the surface mount material is imaged in the detection camera 26. By the position and direction of the notch, the actual direction of the surface mount material being detected can be identified.

[0071] like Figure 4-7 As shown, the first detection light guide plate 22 has a first through hole 221, and the detection base 21 has a first vacuum adsorption port 211 communicating with the first through hole 221. The first vacuum adsorption port 211 is used for vacuum adsorption of the patch material to be tested. It should be noted that, through the adsorption effect of the first vacuum adsorption port 211, the patch material conveyed by the feeding mechanism 1 can be adsorbed and fixed, so that the patch material enters the detection position in sequence, preventing the patch material conveyed later from interfering with the patch material of the previous patch material.

[0072] like Figure 4-7As shown, the first detection light guide plate 22 is provided with a second through hole 222, and the detection base 21 is provided with a second vacuum adsorption port 212 communicating with the second through hole 222. The second vacuum adsorption port 212 is used for vacuum adsorption of the patch material to be detected. It should be noted that the adsorption effect of the second vacuum adsorption port 212 facilitates the detection camera 26 to detect and identify the patch material.

[0073] like Figure 4-7 As shown, the second detection light guide plate 23 is provided with an adsorption groove 232 communicating with the second detection notch 231, the first detection light guide plate 22 is provided with a third through hole 223 communicating with the adsorption groove 232, and the detection base 21 is provided with a third vacuum adsorption port 213 communicating with the third through hole 223. The third vacuum adsorption port 213 is used to adsorb the patch material to be tested into place.

[0074] It should be noted that the material to be tested is adsorbed into place by the adsorption effect of the third vacuum adsorption port 213, and is adsorbed and fixed on the first detection light guide plate 22 by the adsorption effect of the second vacuum adsorption port 212, so that the detection camera 26 can detect and identify the material.

[0075] like Figure 7 As shown, the width of the adsorption tank 232 is smaller than the width of the patch material to be tested. It should be noted that because the width of the adsorption tank 232 is smaller than the width of the patch material to be tested, it can prevent the patch material from entering the adsorption tank 232.

[0076] like Figure 4-7 As shown, both the first detection light guide plate 22 and the second detection light guide plate 23 are made of light-transmitting material. In specific implementation, both the first detection light guide plate 22 and the second detection light guide plate 23 are made of glass, which facilitates the guidance of the diffuse reflection light source provided by the backlight 25, so that the patch material is imaged in the detection camera 26.

[0077] like Figure 1 , Figure 2 and Figure 8-10 As shown, the steering mechanism 3 includes a steering frame 31, on which a first steering seat 32 is rotatably connected, and a second steering seat 33 is detachably connected to the first steering seat 32. The second steering seat 33 has a placement slot 331 for placing the patch material to be steered, and a steering motor 34 for driving the first steering seat 32 to rotate is installed on the steering frame 31.

[0078] like Figure 8-10 As shown, the placement slot 331 is square in shape.

[0079] like Figure 8-10As shown, a steering adsorption tube 35 is installed at one end of the first steering seat 32, and a first adsorption channel 321 communicating with the steering adsorption tube 35 is opened in the first steering seat 32. A second adsorption channel 332 is opened in the second steering seat 33, one end of the second adsorption channel 332 communicating with the first adsorption channel 321, and the other end of the second adsorption channel 332 communicating with the placement groove 331.

[0080] like Figure 8-10 As shown, the cross-sections of the first adsorption channel 321 and the second adsorption channel 332 are both circular, and the inner diameter of the first adsorption channel 321 is larger than the inner diameter of the second adsorption channel 332.

[0081] like Figure 1 , Figure 2 and Figure 11-15 As shown, the material handling mechanism 4 includes a handling base 41 and a handling frame 42. A handling motor 43 is installed on the handling base 41, and a first handling component 44 and a second handling component 45 are sequentially installed on the handling frame 42. A sliding assembly 46 connected to the handling frame 42 is provided on the handling base 41. The handling motor 43 is used to drive the handling frame 42 to move so that the first handling component 44 vacuum adsorbs the patch material on the detection mechanism 2 and transports it to the turning mechanism 3, and the second handling component 45 vacuum adsorbs the patch material on the turning mechanism 3 and transports it to the feeding mechanism 5.

[0082] It should be noted that, through the driving action of the conveying motor 43 and the transmission action of the sliding component 46, the first conveying component 44 and the second conveying component 45 are driven to move in a curved path, so that the first conveying component 44 vacuum adsorbs the patch material on the detection mechanism 2 and transports it to the turning mechanism 3, and the second conveying component 45 vacuum adsorbs the patch material on the turning mechanism 3 and transports it to the feeding mechanism 5, thereby realizing the synchronous transport of patch material between multiple workstations.

[0083] like Figure 11-15 As shown, a buffer frame 47 is fixedly connected to the transport base 41. Both the first transport member 44 and the second transport member 45 pass through the buffer frame 47. The first transport member 44 is fitted with a first spring 48 that abuts against the buffer frame 47, and the second transport member 45 is fitted with a second spring 49 that abuts against the buffer frame 47. It should be noted that both the first spring 48 and the second spring 49 serve a buffering function, facilitating the cushioning of the movement of the first transport member 44 and the second transport member 45, thus enabling flexible adsorption of patch materials.

[0084] like Figure 11-15As shown, the first transport component 44 includes a first transport sleeve 441 embedded in the transport frame 42, and a first transport tube 442 for vacuum adsorption of the material to be bonded is embedded in the first transport sleeve 441. It should be noted that the first transport tube 442 performs vacuum adsorption, which facilitates the adsorption of the bonded material, realizes rapid pick-and-place of the bonded material, and does not damage the bonded material, thereby reducing the loss of the bonded material.

[0085] like Figure 11-15 As shown, the second transport component 45 includes a second transport sleeve 451 embedded in the transport frame 42, and a second transport tube 452 for vacuum adsorption of the material to be bonded is embedded in the second transport sleeve 451. It should be noted that the second transport tube 452 performs vacuum adsorption, which facilitates the adsorption of the bonded material, realizes rapid pick-and-place of the bonded material, and does not damage the bonded material, thereby reducing the loss of the bonded material.

[0086] like Figure 11-15 As shown, the sliding assembly 46 includes a first slide rail 461, a first slider 462, a second slide rail 463, and a second slider 464. The first slide rail 461 is fixedly connected to the transport base 41, the first slider 462 is slidably connected to the first slide rail 461, the second slide rail 463 is fixedly connected to the first slider 462, the second slider 464 is slidably connected to the second slide rail 463, and the transport frame 42 is fixedly connected to the second slider 464. In a specific implementation, the first slide rail 461 and the second slide rail 463 are arranged vertically.

[0087] It should be noted that the sliding component 46 has only one guide rail and one slider in both the horizontal and vertical directions. Compared with the traditional configuration of two guide rails and two sliders, this greatly reduces the weight of the PPU robot, giving it a smaller moment of inertia and faster speed.

[0088] It should also be noted that, in order to prevent the PPU robot arm from shaking, the transport motor 43 is connected to the transport frame 42 through an eccentric wheel, which shortens the distance between the eccentric wheel and the first slider 62 and reduces the impact of the gap of the first slider 62 on the first transport component 4 and the second transport component 5.

[0089] like Figure 1 As shown, the feeding mechanism 5 includes a feeding base 51, a feeding motor 52, and a feeding rack 53. The feeding rack 53 is slidably connected to the feeding base 51. The feeding motor 52 is used to drive the feeding rack 53 to move linearly. The feeding rack 53 is used to load the material to be applied.

[0090] like Figure 1 , Figure 2 and Figure 16-18As shown, the feeding rack 53 includes a first feeding plate 531 and a second feeding plate 532 that are detachably connected. The first feeding plate 531 has several feeding slots 5311 arranged in a straight line and spaced apart. The feeding slots 5311 communicate with the opposite side walls of the first feeding plate 531. It should be noted that the feeding rack 53 is driven to move linearly on the feeding base 51 by the feeding motor 52, causing the feeding slots 5311 to move linearly and receive the patch material.

[0091] like Figure 18 As shown, the bottom of the feeding tank 5311 is provided with a feeding adsorption port 5312 for vacuum adsorption of the material to be bonded. It should be noted that the feeding adsorption port 5312 performs vacuum adsorption to adsorb and fix the bonding material in the feeding tank 5311.

[0092] In practical implementation, both the first transport pipe 42 and the second transport pipe 52 are equipped with pagoda connectors for direct connection to the air pipe. Compared with the traditional threaded installation method, the pagoda connectors reduce the number of accessories required and effectively reduce the weight of the first transport component 44 and the second transport component 45. The transport frame 42 has three mounting holes, through which the first transport sleeve 441 and the second transport sleeve 451 are inserted. The three mounting holes limit the movement of the first transport component 44 and the second transport component 45. In addition, the first transport sleeve 441 has a first abutment surface with a flat surface, and the second transport sleeve 451 has a second abutment surface with a flat surface, which prevents the first transport component 44 and the second transport component 45 from rotating.

[0093] In the specific implementation process, both the first spring 48 and the second spring 49 are in a compressed state, providing initial pressure to the first adsorption tube 442 and the second adsorption tube 452, and preventing the first transport tube 442 and the second transport tube 452 from making hard contact with the patch material, thus achieving flexible adsorption. The first transport sleeve 441 and the second transport sleeve 451 are both embedded in the transport frame 42, which can reduce the weight of the PPU robot. The first transport sleeve 441 and the second transport sleeve 451 are made of hard materials, which can reduce wear on the first transport tube 442 and the second transport tube 452.

[0094] Working principle: The material handling mechanism 4 synchronously transports the surface mount materials in the detection mechanism 2 and the turning mechanism 3. The surface mount materials in the detection mechanism 2 are transported to the turning mechanism 3, and the surface mount materials in the turning mechanism 3 are transported to the feeding mechanism 5. This provides a feeding device for the surface mount machine, realizing the synchronous transport of surface mount materials between multiple stations, improving the feeding rate, and thus improving the production efficiency of the surface mount machine.

[0095] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
