Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to an RFID packaging machine with horizontally distributed turntables. Background Art

[0002] When packaging electronic tags, an RFID packaging machine is required. When the packaging machine is working, the ejector pins on it move to eject the chip below it from the wafer. After the chip is received by the wafer-taking turntable below the wafer, it is transported to the wafer-loading turntable through rotation, and then the wafer-loading turntable transports it to the strip antenna that is adsorbed and driven by the vacuum air drum.

[0003] In traditional packaging machines, in order to detect whether the chip is installed in the correct position of the strip antenna in the correct posture, cameras need to be set on both sides of the vacuum air drum. At the same time, a set of adjustment mechanisms need to be set for the cameras to monitor the status of chips at different positions on the strip antenna. In traditional packaging machines, the loading turntable is located below the unloading turntable (that is, the two are distributed longitudinally), which occupies the longitudinal space. Therefore, the adjustment mechanism can only be set as a manually driven structure. This structure needs to be manually driven for adjustment during use, which is time-consuming and labor-intensive and will delay the overall production efficiency.

[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0007] The 0 o'clock direction of the film-taking turntable 1 is the receiving position A, the 3 o'clock direction is the feeding position B, the 9 o'clock direction of the film-loading turntable 2 is the taking position C corresponding to the feeding position B of the film-taking turntable 1, the 3 o'clock direction of the film-loading turntable 2 is the camera shooting position D, and the 6 o'clock direction is the adsorption feeding position E.

[0018] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 5 As shown: an RFID packaging machine with horizontally distributed turntables, comprising a film taking turntable 1 and a film loading turntable 2, wherein the film taking turntable 1 is located below a wafer 3, an ejector pin 4 is arranged above the wafer 3, and four suction nozzle drive adjustment mechanisms 5 evenly distributed in the circumferential direction are arranged on the film taking turntable 1 and the film loading turntable 2, and a suction nozzle 6 is arranged at the working end of the suction nozzle drive adjustment mechanism 5, the central axes of the film taking turntable 1 and the film loading turntable 2 are located at the same horizontal height, and the film loading turntable 2 is located above a vacuum air drum 7,

[0019] The 0 o'clock direction of the film-taking turntable 1 is the receiving position A, the 3 o'clock direction is the feeding position B, the 9 o'clock direction of the film-loading turntable 2 is the taking position C corresponding to the feeding position B of the film-taking turntable 1, the 3 o'clock direction of the film-loading turntable 2 is the camera shooting position D, and the 6 o'clock direction is the adsorption feeding position E.

[0020] A first corner camera 8 is also provided in the packaging machine, and the first corner camera 8 is aimed at a camera shooting position D of the loading turntable 2 .

[0021] A camera adjustment mechanism is respectively arranged on both sides of the vacuum air drum 7, and the camera adjustment mechanism includes two arc guide rails 9 respectively located on both sides of the vacuum air drum 7, and a slide 10 is slidably connected to the arc guide rail 9, and a camera bracket 11 is arranged on the slide 10, and a second corner camera 12 is arranged on the camera bracket 11, and the camera adjustment mechanism also includes an electric push rod 13 connected to the slide 10, and the end of the output shaft of the electric push rod 13 is rotatably connected to the slide 10, and the tail end of the electric push rod 13 is hinged to the frame of the packaging machine, and a positioning cylinder 14 is also arranged on the slide 10, and a friction positioning plate 15 is connected to the working end of the positioning cylinder 14, and the friction positioning plate 15 matches the end face of the arc guide rail 9.

[0022] The rotating axes of the film-taking turntable 1 and the film-loading turntable 2 are both perpendicular to the operating plane of the staff.

[0023] The working process of the RFID packaging machine with horizontally distributed turntables in the embodiment of the utility model is as follows: the ejector pin 4 moves downward to push a chip located directly below it to the receiving position A of the film-taking turntable 1. At this time, the suction nozzle driving adjustment mechanism 5 located at the receiving position A drives the suction nozzle 6 to move and adsorb the chip. After the ejector pin 4 returns to its position, the film-taking turntable 1 rotates one beat (one beat is 90°) to transport the current chip to the feeding position B. Then the suction nozzle driving adjustment mechanism 5 moves and cooperates with the suction nozzle driving adjustment mechanism 5 located at the taking position C on the film-loading turntable 2. The suction nozzle 6 at the feeding position B does not inhale, and the suction nozzle 6 at the taking position C inhales, thereby transferring the chip to the film-loading turntable 2.

[0024] The loading turntable 2 rotates according to the beat. When it rotates two beats, the chip moves to the camera shooting position D. The first corner camera 8 corresponding to the position takes a picture of the chip and sends the image information to the control system. The program preset in the control system determines whether the posture of the chip is correct. If it is correct, no adjustment signal is sent. If it is not correct, a signal is sent to the nozzle drive adjustment mechanism 5 corresponding to the chip. The nozzle drive adjustment mechanism 5 adjusts the posture of the nozzle (and the chip thereon) to adjust it to the correct posture.

[0025] When the chip loading turntable 2 drives the chip to rotate to the adsorption feeding position E, the suction nozzle 6 stops sucking air, and the chip is adsorbed on a specific position of the strip antenna under the action of the vacuum air drum 7 below it; the vacuum air drum 7 drives the strip antenna (and the chip thereon) to move, and transports the chip to the subsequent process;

[0026] During the movement of the strip antenna, the two second corner cameras 12 located on both sides of the vacuum air drum 7 will collect the image information of the strip antenna in real time to monitor the movement state of the strip antenna and check whether the position of the chip installed on the strip antenna meets the requirements;

[0027] When the second corner camera 12 is working, the electric push rod 13 is extended or retracted, driving the slide 10 to slide back and forth on the arc guide rail 9. Under the guidance of the arc guide rail 9, the motion trajectory of the slide 10 in space is an arc shape, thereby ensuring that the shooting angle of the second corner camera 12 is always distributed along the radial direction of the vacuum drum 7;

[0028] After being adjusted to a suitable position, the electric push rod 13 stops moving, and at the same time, the control system sends a signal to the positioning cylinder 14, which drives the friction positioning piece 15 to extend toward the direction of the arc guide rail 9. The friction positioning piece 15 is pressed against the surface of the arc guide rail 9. The friction force between the two allows the slide seat 10 to be positioned with the arc guide rail 9.

[0029] The rotating axes of its film retrieval turntable and film loading turntable are perpendicular to the staff's operating plane, which means that the operator can see the complete film retrieval turntable and film loading turntable in the direction of the operating plane. On the one hand, it is convenient to observe the transportation and installation of the strip antenna and chip, and on the other hand, it is also convenient to find problems and maintain at any time.
