[0060] The embodiments of the present application disclose an RFID flip-chip mounting device.

[0061] Please refer to Figure 1 and Figure 2 , an embodiment of an RFID flip-chip mounting device provided in the embodiments of the present application includes:

[0062] A fixed base 100, a rotation driving device 300, a reciprocating driving device 200, and a mounting suction head 400. Among them, the reciprocating driving device 200 is installed on the fixed base 100 and is connected to the rotation driving device 300 for driving the rotation driving device 300 to reciprocate. The fixed base 100 is used as a bearing structure, and its specific structure can be designed according to actual needs, as long as it can at least install and fix the rotation driving device 300 and the reciprocating driving device 200, without limitation.

[0063] Regarding the rotation driving device 300, it includes a rotation motor 301 and a flexible buffer rotation mechanism. Among them, the flexible buffer rotation mechanism includes a motor connecting rod 302, an air inlet seat 304, a first connection head 305, a second connection head 306, an elastic member 307, a ventilation guide rod 309, and a flexible air pipe 312.

[0064] The air inlet seat 304 is installed on the fixed base 100 and is located below the output shaft 3011 of the rotation motor 301. The air inlet seat 304 is provided with a through cavity 3041 that penetrates itself and corresponds to the output shaft 3011 from top to bottom. The structure of the air inlet seat 304 is not limited.

[0065] The motor connecting rod 302 is rotatably disposed along the central axis direction of the through cavity 3041, that is, the central axis of the motor connecting rod 302 coincides with the central axis of the through cavity 3041. The rotational fit between the motor connecting rod 302 and the air inlet seat 304 can be achieved through radial bearings. For example, radial bearings are respectively installed at both port positions of the through cavity 3041 on the air inlet seat 304, and the motor connecting rod 302 passes through the radial bearings to realize the connection and fit with the air inlet seat 304.

[0066] One end of the motor connecting rod 302 facing the rotary motor 301 is synchronously rotationally connected to the output shaft 3011 of the rotary motor 301. A connection hole can be opened at one end of the motor connecting rod 302 facing the rotary motor 301, and then the output shaft 3011 is inserted and locked by a pin fastener. The other end of the motor connecting rod 302 is synchronously rotationally connected to the first connector 305, and its connection and fit method can be the same as above. Of course, other synchronous rotational connection means can also be used for synchronous rotational connection, without limitation.

[0067] The outer diameter of the rod section of the motor connecting rod 302 located in the through cavity 3041 is smaller than the inner diameter of the through cavity 3041, so that a conduction gap is formed between the outer wall of the rod section and the inner wall of the through cavity 3041. In order to seal the conduction gap and not affect the rotation of the motor connecting rod 302, sealing rings 303 are respectively provided between the rod section of the motor connecting rod 302 located in the through cavity 3041 and the through cavity 3041 near both openings of the through cavity 3041. The sealing ring 303 can be fixedly embedded in the rod section of the motor connecting rod 302 and in rotational sealing contact with the inner wall of the through cavity 3041, or fixedly embedded on the inner wall of the through cavity 3041 and in rotational sealing contact with the outer wall of the rod section of the motor connecting rod 302.

[0068] A first air guide channel 3021 is provided in the motor connecting rod 302. A plurality of through holes 3022 communicating with the first air guide channel 3021 are provided at a position between the two sealing rings 303 on the rod section of the motor connecting rod 302 located in the through cavity 3041. A first air joint 3042 communicating with the first air guide channel 3021 is provided on an outer side wall of the air inlet seat 304. Through the above design, even if the motor connecting rod 302 rotates, its own through holes 3022 can always be in communication with the first air joint 3042, and the first air joint 3042 can be used to connect a vacuum pump.

[0069] The first connector 305 is movably connected to the second connector 306 through an elastic member 307, and there is an elastic buffer gap between the first connector 305 and the second connector 306 in the reciprocating motion direction of the rotary drive device 300. When the first connector 305 rotates, it synchronously drives the second connector 306 to rotate. Through the formed elastic buffer gap, a certain elastic buffer displacement can be provided for the mounting suction head 400, so that when the mounting suction head 400 mounts the chip, it can better adhere to the chip, and at the same time, the provided buffer displacement can also prevent the chip from being crushed.

[0070] A second air guide channel 3051 is provided in the first connector 305, and a second air joint 310 communicating with the second air guide channel 3051 is further provided on an outer side wall of the first connector 305; a third air guide channel 3061 is provided in the second connector 306, and a third air joint 311 communicating with the third air guide channel 3061 is provided on an outer side wall of the second connector 306; the second air joint 310 and the third air joint 311 are connected and conducted through an air pipe 312. The air pipe 312 is designed to be flexible to avoid interfering with the elastic buffer gap.

[0071] One end of the ventilation guide rod 309 is connected to the second connector 306 and communicates with the third air guide channel 3061. The other end of the ventilation guide rod 309 is connected to the mounting suction head 400 and communicates with the suction nozzle of the mounting suction head 400. The ventilation guide rod 309 is also connected in a synchronous rotation manner with the second connector 306, and its connection method can also refer to the synchronous rotation connection and cooperation between the motor connecting rod 302 and the output shaft 3011 proposed above, and no specific limitation is made.

[0072] As can be seen from the above technical solution, the entire air pipe 312 path connected to the nozzle of the pick-and-place nozzle 400 of the present application is respectively composed of the through cavity 3041 area between two sealing rings 303, the first air guide channel 3021 provided inside the motor connecting rod 302, the second air guide channel 3051 provided inside the first connector 305, the air pipe 312, the third air guide channel 3061 provided inside the second connector 306, and the air vent guide rod 309. Only the air vent guide rod 309 and the air pipe 312 are exposed outside the entire air pipe 312 path, and the others are basically hidden designs, minimizing the layout of external pipes as much as possible, making the overall device structure compact and streamlined. Moreover, the first connector 305 is movably connected to the second connector 306 through an elastic member 307, and there is an elastic buffer gap between the first connector 305 and the second connector 306 in the reciprocating movement direction of the rotary drive device 300. Such a design enables the pick-and-place nozzle 400 to have a certain elastic displacement in the reciprocating movement direction, so as to achieve high-speed and high-precision fitting. Generally speaking, the present application provides a flexible buffer rotation mechanism between the rotary motor 301 and the pick-and-place nozzle 400, which not only ensures the rotation control of the rotary motor 301 and the pick-and-place nozzle 400, but also reduces the layout of external pipes, making the overall device miniaturized and lightweight, and enabling the pick-and-place nozzle 400 to have a certain elastic displacement in the reciprocating movement direction, so as to better achieve high-speed and high-precision fitting.

[0073] The above is the first embodiment of an RFID flip-chip mounting device provided by the present application. The following is the second embodiment of an RFID flip-chip mounting device provided by the present application. For details, please refer to Figures 1 to 4 。

[0074] Based on the solution of the above Embodiment 1:

[0075] Further, in terms of the structural composition of the reciprocating drive device 200, it includes a linear motor 201, a grating reader 203, and a photoelectric switch 204. Among them, the linear motor 201 is arranged beside the rotary motor 301, and the driving end of the linear motor 201 is specifically connected to the rotary motor 301 through a connecting arm 202, so as to drive the overall reciprocating movement of the rotary drive device 300, and then drive the pick-and-place nozzle 400 to reciprocate.

[0076] The grating reader 203 is arranged above the connecting arm 202 for positioning the connecting arm 202. The photoelectric switch 204 is arranged above the rotary motor 301, and a trigger portion 3012 for triggering the photoelectric switch 204 is provided at a position on the rotary motor 301 far from its output shaft 3011. By combining the positioning of the grating reader 203 with the movement of the connecting arm 202 and the positioning of the photoelectric switch 204 for the rotary motor 301, the position accuracy during the up and down movement of the pick-and-place nozzle 400 can be better guaranteed.

[0077] Further, the linear motor 201 can be a voice coil motor, which has the advantages of small volume and light weight, and is suitable for high-speed short-distance reciprocating motion. With the position feedback of the grating read head 203, high-precision, high-speed and high-frequency up-and-down mounting of the mounting suction head 400 can be achieved.

[0078] Further, a guide rail 101 is provided on the fixed seat 100. The guide rail 101 can be a micro guide rail 101 without limitation. An installation plate 313 is externally connected to the rotary motor 301, and the installation plate 313 is slidably matched with the guide rail 101. Thus, the rotary motor 301 can be slidably matched with the fixed seat 100. Through the sliding match with the guide rail 101, the movement of the rotary motor 301 is also more stable and reliable.

[0079] Further, regarding the cooperation between the first connector 305 and the second connector 306, the first connector 305 includes a connection block 3052 and a T-shaped limit block 3053. On one side of the connection block 3052 facing the other end of the motor connecting rod 302, a first annular protrusion 3055 for the other end of the motor connecting rod 302 to extend into is provided, and a second air guide channel 3051 is provided at the bottom of the first annular protrusion 3055. The design of the first annular protrusion 3055 facilitates the synchronous rotational connection between the first connector 305 and the motor connecting rod 302, and also facilitates the connection and conduction between the first air guide channel 3021 and the second air guide channel 3051. In this application, a second annular protrusion 3064 for the ventilation guide rod 309 to extend into movably can be provided on the side of the second connector 306 facing the mounting suction head 400, and a corresponding third ventilation channel can be provided at the bottom of the second annular protrusion 3064. Such a setting facilitates the synchronous rotational connection and cooperation between the second connector 306 and the ventilation guide rod 309, and also facilitates the conduction between the third air guide channel 3061 and the ventilation guide rod 309.

[0080] One end of the vertical portion of the limit block 3053 is vertically and integrally connected to the middle of the side of the connection block 3052 facing away from the other end of the motor connecting rod 302. An opening groove 3062 which is T-shaped and for connection and cooperation is provided on the second connector 306. The cooperation between the T-shaped limit block 3053 and the opening groove 3062 enables the first connector 305 and the second connector 306 to be movably connected and cooperated in the reciprocating direction, and at the same time can limit the movement of the first connector 305 or the second connector 306 to prevent the first connector 305 and the second connector 306 from separating.

[0081] An elastic buffer gap is formed between the side of the connection block 3052 facing away from the other end of the motor connecting rod 302 and the side of the second connector 306 facing the connection block 3052. An elastic member 307 is installed between the first connector 305 and the second connector 306. One end of the elastic member 307 is in contact and abuts against the first connector 305, and the other end is in contact and abuts against the second connector 306.

[0082] Furthermore, in order to make the connection between the first connector 305 and the second connector 306 more stable and reliable, at least two guide pillars 308 are connected between the first connector 305 and the second connector 306, and the at least two guide pillars 308 pass through the connecting block 3052, the second connector 306 at the opening groove 3062 and the limit block 3053 in sequence.

[0083] Furthermore, the elastic member 307 can be a spring. Taking the spring as an example, the compression amount of the spring can be designed to be adjustable, so that the mounting pressure can be controlled within a certain range by adjusting the compression amount of the spring, and the chip can be prevented from being crushed, and the applicability is also better.

[0084] Furthermore, the number of springs is specifically two, and the side of the connecting block 3052 facing away from the other end of the motor connecting rod 302 is provided with first grooves 3054 corresponding to the springs on both sides of the limit block 3053; the second connecting head 306 is provided with second grooves 3063 corresponding to the first grooves 3054 on the side facing the connecting block 3052, one end of the spring extends into the first groove 3054, and the second end extends into the second groove 3063.

[0085] To adjust the spring compression, an adjustment screw 3056 is mounted on the connecting block 3052 and corresponds to the first groove 3054. One end of the adjustment screw 3056 movably extends into the first groove 3054 and contacts the spring. By rotating the adjustment screw 3056, the extent to which the end of the adjustment screw 3056 extends into the first groove 3054 is controlled, thereby adjusting the spring compression. Of course, the adjustment screw 3056 can also be replaced with other threaded adjustment members without limitation.

[0086] Furthermore, in order to support and limit the ventilation guide rod 309 without affecting the rotation and axial displacement of the ventilation guide rod 309, and to further improve the stability and reliability of the device, a bearing seat 501 is also provided on the fixed seat 100. Among them, two bearings 503 and a guide sleeve 502 are spaced apart in the bearing seat 501; the bearings 503 can be deep groove ball bearings, and there is no specific limitation. The guide sleeve 502 is connected between the two bearings 503, and the ventilation guide rod 309 moves through the guide sleeve 502. The guide sleeve 502 can provide a limiting support for the ventilation guide rod 309, and at the same time will not affect the rotation and axial displacement of the ventilation guide rod 309.

[0087] Furthermore, the rotating motor 301 may be a stepper motor. The high-precision stepper motor has a step angle of 0.72 degrees and weighs only 200g, which can ensure accurate angles during chip placement and further reduce the weight of the entire device.

[0088] The above has introduced in detail a kind of RFID flip-chip mounting device provided by the present application. For those of ordinary skill in the art, according to the idea of the embodiments of the present application, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present application.
