DETAILED DESCRIPTION

[0024] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4 The present invention provides a defective product return device, comprising a flip seat 1 and a pushing mechanism 2, wherein the top surface of the flip seat 1 is in an inclined state, and a shift piece 3 is arranged on the flip seat 1. When an electrolytic capacitor 4 is placed on the top surface of the flip seat 1, the electrolytic capacitor 4 can rotate against the shift piece 3 under the action of gravity to stand on a temporary workstation of the defective product return device, and the pushing mechanism 2 is used to push the electrolytic capacitor 4 away from the temporary workstation. In the prior art, the method of using a fully automatic sorting machine to return defective electrolytic capacitors (electrolytic capacitors with quality problems) is that a robot clamps the defective electrolytic capacitors and throws the defective electrolytic capacitors directly into a defective product box. Throwing the products directly down will cause collisions between the terminals and the sleeves, affecting the rework time cost and the raw material cost. The present invention provides a defective product return device. When in use, the defective electrolytic capacitor can be placed on a flip seat 1 by a robot. Since the top surface of the flip seat 1 is in an inclined state, the defective electrolytic capacitor will tend to slide downward under the action of gravity. Since a gear member 3 is provided on the flip seat 1, the electrolytic capacitor 4 can rotate against the gear member 3 to stand on a temporary workstation of the defective product return device. The pushing mechanism 2 then pushes the electrolytic capacitor 4 on the temporary workstation away. Through the defective product return device, the defective electrolytic capacitor is automatically turned over and stood up, which is conducive to the defective electrolytic capacitor moving to the return area and being stacked in the return area in a standing posture. In addition, it should be noted that when the defective electrolytic capacitor is placed on the flip seat 1 by the robot, the terminals of the electrolytic capacitor face downward, and by flipping, the terminals of the electrolytic capacitor face upward, so that the electrolytic capacitor is in a standing state.

[0026] As an optional implementation of the embodiment of the present invention, the defective product return device further includes a limiting structure 12, and there is a distance between the limiting structure 12 and the flip seat 1, and a temporary workstation is formed between the two. Figure 1 , schematically shows the limiting structure 12, which is a plate-shaped structure. The limiting structure 12 can effectively prevent the electrolytic capacitor 4 from tipping over in the direction of the limiting structure 12, which is conducive to the electrolytic capacitor 4 standing on the temporary workstation. In order to facilitate the inverted electrolytic capacitor, the top surface of the flip seat 1 is preferably tilted at an angle of 32° to 38°, and the height of the limiting structure 12 is preferably equal to, slightly higher than, or slightly lower than the height of the electrolytic capacitor.

[0027] As an optional implementation method of the present invention, the defective product return device includes a bracket 5, the two opposite sides of the flip seat 1 are supported on the bracket 5 and the flip seat 1 is rotatably connected to the bracket 5, two gears 3 are arranged on the flip seat 1 and the electrolytic capacitor 4 can be placed between the two gears 3, and the position of the flip seat 1 can be adjusted to make one of the gears 3 higher than the other gear, and each gear corresponds to a temporary workstation. Figure 1 and Figure 2 , schematically illustrates the structure of the flip seat 1 and the connection relationship between the flip seat 1 and the bracket 5. Two gear members 3 are arranged on the flip seat 1, and the flip seat 1 can swing like a "seesaw", so that one of the gear members 3 is higher than the other gear member 3, so that the defective electrolytic capacitors placed on the flip seat 1 can be flipped and stand on different temporary workstations, and then the electrolytic capacitors located at different temporary workstations are pushed away respectively through the corresponding pushing mechanism 2. The flip seat 1 is set as a "seesaw" structure and two gear members 3 are arranged, mainly considering that the defective electrolytic capacitors are divided into defective capacity products and short-circuit defective products. The two different types of defective products can be flipped and inverted at different temporary workstations by the flip seat 1, so as to be moved to different material withdrawal areas.

[0028] As an optional implementation method of the embodiment of the present invention, the defective product return device also includes a flip driving mechanism 6, which is connected to the flip seat 1, and can drive the flip seat 1 to swing. The specific structure of the flip driving mechanism 6 can be as follows: the flip driving mechanism 6 includes a driving cylinder 601 and a connecting plate structure 602, the output end of the driving cylinder 601 is connected to the connecting plate structure 602, and a connecting rod 603 is provided on the flip seat 1, and the connecting rod 603 is inserted into the groove on the connecting plate structure 602. When the driving cylinder 601 drives the connecting plate structure 602 to move horizontally, the connecting plate structure 602 can drive the connecting rod 603 to swing. See Figure 3 and Figure 4 , showing that the flip driving mechanism 6 is connected to the flip seat 1, and the connecting plate structure 602 connected to the driving cylinder 601 is a bent plate, see Figure 4 , illustrating the coordination relationship between the connecting rod 603 and the connecting plate structure 602. When the driving cylinder is actuated, the connecting rod 603 and the connecting plate structure 602 are coordinated to realize the swing of the flip seat 1, thereby realizing that the electrolytic capacitor with poor capacity and the electrolytic capacitor with short circuit can be flipped and inverted at different temporary workstations.

[0029] As an optional implementation method of the embodiment of the present invention, the driving cylinder 601 is connected to the control device, and the control device can control the action of the driving cylinder 601 to realize that different categories of defective electrolytic capacitors 4 fall to different temporary workstations respectively. The defective product return device provided by the present invention is installed on a fully automatic aging sorting machine. The fully automatic aging sorting machine clamps the defective electrolytic capacitors with poor capacity and poor open circuit to the flip seat 1 through a translation conveyor clamp (manipulator) according to the performance test results of the products produced. The defective type signal emitted by the aging sorting machine is transmitted to the control device. After receiving the signal and processing it, the control device sends a command to the flip seat 1 to control the tilting direction of the flip seat 1. According to the tilting direction, the defective electrolytic capacitor automatically flips and stands on the flip seat 1, and stands on the corresponding temporary workstation.

[0030] As an optional implementation method of the present invention, see Figure 1 The defective product return device is formed with a return area 11 for accommodating defective products. Each temporary workstation corresponds to a return area 11. The defective product return device also includes a material guide structure 7. The pushing mechanism 2 can push the electrolytic capacitor 4 on the temporary workstation to the material guide structure 7, and the moving electrolytic capacitor 4 can push the adjacent electrolytic capacitor 4 to facilitate the electrolytic capacitor 4 to move to the return area 11. Figure 1 , schematically shows the material guide structure 7, which is an arc-shaped plate and the concave side of the material guide structure 7 faces the push rod 201 on the push mechanism 2 for pushing the electrolytic capacitor 4. Figure 1 When the pushing mechanism 2 pushes the electrolytic capacitor 4 on the temporary station to the guide structure 7, the electrolytic capacitors 4 are in contact with each other, and under the action of the guide structure 7, the electrolytic capacitors 4 move to the material withdrawal area 11 under the mutual thrust, avoiding the accumulation of products near the temporary station, completing the material withdrawal action, and realizing the automatic discharge of defective electrolytic capacitors to the corresponding material withdrawal area 11. After the defective product withdrawal device provided by the present invention is put into use, it avoids mutual collision and contact between products during the material withdrawal process, eliminates the contact between the terminal of the electrolytic capacitor and the sleeve, and avoids the occurrence of defects such as sleeve scratches and terminal deformation.

[0031] See also Figure 1 The defective product return device also includes a return tray 8 and an intermediate tray 9. A connecting frame or a supporting frame is arranged below the return tray 8 and the intermediate tray 9.

[0032] As an optional implementation of the embodiment of the present invention, the push mechanism 2 includes a push cylinder 202 and a push rod 201. The output shaft of the push cylinder 202 is connected to the push rod 201. The push rod 201 passes through the intermediate tray 9 and is arranged opposite to the material guide structure 7. The intermediate tray 9 is provided with an avoidance bar groove. The push rod 201 moves along the avoidance bar groove driven by the push cylinder 202. Figure 1 , schematically showing that the push cylinder 202 is arranged on the lower side of the intermediate tray 9, and the push rod 201 passes through the intermediate tray 9, Figure 1 It is shown that each push cylinder 202 is connected to two push rods 201, and the push cylinder 202 is driven to drive the push rod 201 to push the electrolytic capacitor 4 on the temporary station. Specifically, a sensor can be set on the temporary station. When the sensor detects the presence of the electrolytic capacitor 4 on the temporary station, the sensor transmits a signal to the control device, and the control device controls the corresponding push mechanism 2 to make a corresponding action. When the push mechanism 2 pushes the electrolytic capacitor 4 on the temporary station (so that other defective electrolytic capacitors 4 can be turned over and stand on the temporary station to achieve continuous operation), the push rod 201 is reset to prepare for pushing the next defective electrolytic capacitor.

[0033] See also Figure 1 As for the flip driving mechanism 6 , the flip driving mechanism 6 is located below the middle tray 9 , and the connecting rod 603 passes through the middle tray 9 and is connected to the flip seat body 1 .

[0034] As an optional implementation mode of the embodiment of the present invention, the shift member 3 is a door-shaped rod, and the top of the shift member 3 is an arc shape that bends downward. Figure 2 , schematically shows the shift member 3, which has a simple structure and is convenient for realizing the flipping and inverting of the electrolytic capacitor 4.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
