DETAILED DESCRIPTION

[0012] The specific implementation methods of the present utility model are further described in detail below.

[0013] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the specific implementation methods of the present invention and the corresponding drawings to clearly and completely explain the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] The unqualified electronic component screening inkjet printer of the present invention includes a screening device, which includes a screening station 10. A push-pull cylinder 11 and a guide groove 12 are respectively provided on both sides of the screening station 10. A re-inspection basket 8 is provided at the exit of the guide groove away from the screening station. The push-pull cylinder is controlled by a controller and also includes a coding device. The coding device includes a coding conveyor belt 2 and a flip gripper 9 located between the coding conveyor belt 2 and the screening device. The flip gripper includes a base and a rotating clamping arm installed on the base.

[0016] The controller receives a test signal transmitted from the outside. When the test signal indicates that the electronic component is qualified, the screening device does not perform a screening operation. When the test signal indicates that the electronic component is unqualified, the screening device performs a screening operation.

[0017] The screening operation is that the controller controls the push-pull cylinder 11 to push forward, pushing the electronic components placed on the screening station 10 into the guide groove 12. The electronic components continue to move along the guide groove 12 under the action of inertia and fall into the re-inspection basket 8.

[0018] A preferred embodiment is that the screening station 10 is a negative pressure suction cup, the bottom of the negative pressure is connected to an air pump, the air pump is connected to the controller, and when the electronic components enter the screening device, the circuit board with the pins soldered on it faces downward. The circuit board is generally a smooth PCB board, which is easily adsorbed by negative pressure. The controller controls the air pump to start when the electronic components are placed, and the air pump is turned off after the inspection is completed, so that the push-pull cylinder 11 can push the electronic components into the re-inspection frame or be grabbed by the rotating clamping arm 1 of the coding device 5.

[0019] The electronic components that pass the screening enter the subsequent coding process. The coding device includes a coding conveyor belt 2 and a flip gripper 9 located between the coding conveyor belt 2 and the screening device 4. Figure 2 As shown, the flip gripper 9 includes a base and a rotating clamping arm 1 installed on the base. The coding conveyor belt 2 includes a placement area 4 at the front end, a guide area 5 arranged behind the placement area 4, and a coding area 6 located behind the guide area 5. The guide area 5 is provided with a pair of trumpet-shaped guide plates 7, the larger inlet faces the placement area 4, and the smaller outlet is located in the coding area 6. The width of the smaller opening is generally set to be slightly larger than the width of the electronic component.

[0020] The rotating clamping arm 1 picks up the electronic component placed on the screening station 10, then rotates 180 degrees to place the electronic component on the placement area 4 of the coding conveyor belt 2. While moving the electronic component, the electronic component is flipped 180 degrees so that the circuit board with the pin end is facing upwards;

[0021] The coding conveyor belt 2 moves continuously, pushing the electronic components to the guide area 5, and guiding them through the trumpet-shaped guide plate 7 of the guide area 5, so that no matter where the electronic components are placed in the placement area 4, they will eventually flow from the smaller outlet of the guide area 5 to the coding area 6. An infrared sensor is provided at the outlet of the guide area 5, and the infrared sensor and the coding machine 3 are connected with the coding controller signal. Whenever the infrared sensor detects an electronic component flowing out from the outlet of the guide area 5, a certain delay is set to send out a coding signal according to the speed of the conveyor belt and the distance from the infrared sensor to the coding machine 3, so that when the electronic component is transferred from the outlet of the guide area 5 to the bottom of the coding machine 3, the coding machine 3 starts inkjet coding and completes coding on the circuit board surface of the electronic component.

[0022] The coded electronic components are transported to the finished product platform 14 by the coding conveyor belt 2 .

[0023] The foregoing describes the various preferred embodiments of the present invention. Unless the preferred implementation modes in each preferred embodiment are obviously self-contradictory or based on a certain preferred implementation mode, each preferred implementation mode can be arbitrarily superimposed and used in combination. The embodiments and the specific parameters in the embodiments are only for the purpose of clearly describing the utility model verification process of the utility model creator, and are not intended to limit the scope of patent protection of the present invention. The scope of patent protection of the present invention shall still be based on its claims. Any equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the scope of protection of the present invention.
