[0040] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Fig.10, Fig.11 As shown, the adsorption mechanism 30 includes a first suction pipe 31, a second suction pipe 32, a suction head 33, a second lifting shaft 34, a spring 35, a baffle 36, and a positioning buckle 37.

And for the places where the distance between the straight slots 222 is small, because the turntable 24 has a certain speed when rotating, when the turntable 24 rotates to the interval between the straight slots 222, the product will not fall to the suction head 33.

[0041] In some embodiments, Figure 1 , Figure 3 , Figure 4 Fig. 9 As shown, the lifting part 10 includes an eccentric motor 11, a rotating wheel 12, a first lifting shaft 13, a lifting disk 14, a connecting rod 15, a pressure rod 16, and a pressing piece 17.

The first lifting shaft 13 can pass through the motor rotating tube 212, one end of the first lifting shaft 13 is fixedly connected to the lifting disk 14, and the other end is in contact with the rotating wheel 12, one end of the connecting rod 15 is fixedly arranged on the lifting disk 14, and the other end is fixedly connected to one end of the pressure rod 16, the pressing piece 17 is rollingly arranged on the other end of the pressure rod 16, and the pressing piece 17 can squeeze the baffle 36 to move downward when it moves downward.

[0042] In some embodiments, Figure 4As shown, there are multiple connecting rods 15, one end of each of the multiple connecting rods 15 is fixedly disposed on the lifting plate 14, and the other end is fixedly connected to multiple pressing rods 16. In addition, in some embodiments, as required, the number of the connecting rods 15 can be selected to be smaller than the number of the second lifting shafts 34, and the number of the second lifting shafts 34 can be allocated to different processes according to the assembly and manufacturing process requirements of the chip tantalum capacitor, and the position of the pressing rod 16 can be determined, so as to achieve effective coordination between the up and down movement of the pressing rod 16 and the second lifting shaft 34, so as to improve work efficiency.

[0043] In some embodiments, Figure 2 , Fig.10 As shown, the pressing member 17 is a roller or a ball (not shown in the figure), and the roller is arranged to roll along the tangential direction of the baffle 36 when the baffle 36 rotates. By setting the pressing member 17 as a roller or a ball, when the roller or the ball moves downward to squeeze the baffle 36, and moves upward to separate from the baffle 36, since the rotating part 20 drives the baffle 36 to rotate at a high speed, it is very likely that there will be a moment when the roller or the ball contacts the baffle 36, and the baffle 36 applies a friction force in the tangential direction of the baffle 36 rotation to the roller or the ball. Therefore, setting the pressing member 17 as a roller or a ball can reduce the friction between the pressing member 17 and the baffle 36, and reduce the wear of the baffle 36.

[0045] In the above, the eccentric motor 11 and the servo motor 21 are both electrically connected to an external controller, and the external control can control the eccentric motor 11 and the servo motor 21, and multiple first suction pipes 31 are connected one by one with corresponding solenoid valves. The controller can control the opening and closing of the solenoid valves to achieve the vacuum in the first suction pipes 31 to generate negative pressure, or to achieve the disappearance of negative pressure. The above-mentioned products can be chip tantalum capacitors at the corresponding process.

[0046] The working principle of the utility model is:

[0047] According to the process corresponding to the assembly and manufacturing process of the chip tantalum capacitor (product), a connecting rod 15 is set corresponding to the process. One end of the connecting rod 15 is fixedly connected to the lifting plate 14, and the other end is fixedly connected to the pressure rod 16. The adsorption mechanism 30 is set on the turntable 24 as needed, the controller opens each solenoid valve, and the external air pump evacuates each first suction pipe 31, so that negative pressure is generated between the first suction pipe 31, the suction channel 221, the straight slot 222, the second suction pipe 32, and the suction head 33. The controller controls the servo motor 21 to rotate, the servo motor 21 drives the turntable 24 to rotate, and the turntable 24 drives the second lifting shaft 34 to rotate. When the second lifting rod rotates to the corresponding process, the controller controls the eccentric motor 11 to rotate the rotating wheel 12, and the rotating wheel 12 pushes the first lifting shaft 13 up and down, so that the pressing piece 17 on the pressure rod 16 squeezes the baffle 36 in the adsorption mechanism 30, and the baffle 36 presses the spring 35 so that the spring 35 contracts, and the second lifting rod moves downward, and the product on the suction head 33 enters the corresponding process. After the process is completed, the eccentric motor 11 drives the rotating wheel 12 to rotate, the pressure rod 16 moves upward, the spring 35 is reset, and the second lifting rod moves upward. The product at the suction head 33 is separated from the corresponding process, and when the servo motor 21 drives the rotating disk 24 to rotate, the second lifting rod and the product on the suction head 33 enter the next process until the assembly and manufacturing of the chip tantalum capacitor (product) is completed. The controller closes the electromagnetic valve connected to the first suction pipe 31 corresponding to the chip tantalum capacitor after the assembly and manufacturing is completed, so that the negative pressure in the first suction pipe 31 disappears, and the product at the suction head 33 falls. After the product falls, the controller opens the electromagnetic valve corresponding to the first suction pipe 31, so that negative pressure is generated between the first suction pipe 31 and the suction channel 221, the straight slot 222, the second suction pipe 32, and the suction head 33 corresponding to the first suction pipe 31, and under the action of the corresponding pressing member 17 pressing the baffle 36, the suction head 33 absorbs the product of the corresponding process. In this specific embodiment, the controller can adjust the rotation speed and start-stop interval of the eccentric motor 11 and the stepper motor, and control the opening and closing of the corresponding solenoid valves, so as to achieve the orderly completion of each process in the assembly and manufacturing of chip tantalum capacitors (products).
