Description

Technical Field

[0001] The utility model relates to the technical field of mounting detection, in particular to an intelligent mounting detection mechanism. Background Art

[0002] Surface assembly of printed circuit boards is an extremely important step in the assembly process of electronic devices. Currently, fully automatic assembly mechanisms, namely high-speed placement machines, are commonly used to achieve fully automatic and high-speed surface assembly of circuit boards. After the surface assembly of the circuit board, automatic optical inspection technology is required to detect the accuracy of the positions of various patch components and the soldering quality of the patch components.

[0003] However, the inspection device usually includes a conveyor belt and an automatic inspection device. Usually, the printed circuit boards that have been inspected will continue to be conveyed forward along the conveyor belt regardless of whether they meet the standards, and will not be removed in time. The printed circuit boards that have problems after inspection are usually marked first, and then identified and sorted by humans or machines, which is relatively inconvenient. Utility Model Content

[0004] In order to promptly remove printed circuit boards that do not meet the standards from the conveyor belt and reduce subsequent sorting work, the utility model provides an intelligent placement detection mechanism.

[0005] The utility model provides an intelligent placement detection mechanism, including a conveying device, a rejecting device and a storage component;

[0006] The conveying device includes a frame and a conveyor belt installed on the frame through a driving assembly;

[0007] The rejection device includes a fixed frame, a detector, a cylinder, and a push plate. The fixed frame is arranged on the frame, the detector is arranged inside the fixed frame, the cylinder is arranged on a side wall of the fixed frame, the output end of the cylinder passes through the side wall of the fixed frame and is connected to the push plate, and the bottom wall of the push plate is in contact with the top of the conveyor belt.

[0008] The storage assembly includes an inclined plate and a material receiving box. A discharge hole is opened on the fixed frame. One end of the inclined plate is arranged on the fixed frame, and the other end is arranged at the top opening of the material receiving box.

[0009] By adopting the above technical solution, when the detector detects a circuit board that does not meet the standards, the conveyor belt stops driving, and the cylinder in the rejection device drives the push plate to move in the direction close to the unqualified circuit board, and pushes the unqualified circuit board to the inclined plate outside the discharge hole. The circuit board falls into the receiving box under the action of its own gravity and the inclined plate, completing the rejection operation, and the cylinder is started to move the push plate to the edge of the conveyor belt, making it difficult to affect the subsequent conveying operation of the conveyor belt; therefore, the rejection mechanism can remove the circuit boards that do not meet the standards on the conveyor belt from the surface of the conveyor belt in time, and store them through the storage component, reducing the subsequent sorting work of the circuit boards, which is more convenient.

[0010] Optionally, a plurality of limit rods are provided on the push plate, and one end of the limit rod away from the push plate passes through the fixing frame, and the plurality of limit rods are distributed on both sides of the push plate.

[0011] Optionally, one end of the inclined plate is arranged at the edge of the discharge port, and the other end is arranged to be inclined downward in a direction close to the material receiving box, and baffles are arranged on both sides of the inclined plate.

[0012] Optionally, multiple limiting mechanisms are provided on both sides of the fixed frame, and the limiting mechanisms include a first motor, a drive shaft and a limiting plate. The first motor is arranged on the fixed frame, one end of the drive shaft is connected to the output end of the first motor, and the other end is rotatably arranged on the fixed frame, and the limiting plate is arranged on the side wall of the drive shaft.

[0013] Optionally, a plurality of the limiting plates are arranged on both sides of the push plate.

[0014] Optionally, the driving assembly includes a second motor, multiple side plates and multiple transmission shafts, the side plates are arranged on both sides of the top of the frame, the transmission shaft is rotatably arranged between the multiple side plates, the second motor is arranged on the side plates, and the output end of the second motor is connected to the transmission shaft.

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. When the detector detects a circuit board that does not meet the standards, the conveyor belt stops driving, and the cylinder in the rejection device drives the push plate to move towards the direction close to the unqualified circuit board and push the unqualified circuit board to the inclined plate outside the discharge hole. The circuit board falls into the receiving box under the action of its own gravity and the inclined plate, completing the rejection operation. The cylinder is started to move the push plate to the edge of the conveyor belt, making it difficult for it to affect the subsequent conveying operation of the conveyor belt; therefore, the rejection mechanism can promptly remove the circuit boards on the conveyor belt that do not meet the standards from the surface of the conveyor belt and store them in the storage assembly, reducing the subsequent sorting work of the circuit boards and making it more convenient.

[0021] The following combination Figure 1-Figure 3 The utility model is described in further detail.

[0022] This embodiment discloses an intelligent placement detection mechanism: Figure 1-Figure 3 , an intelligent placement detection mechanism includes a conveying device, a rejecting device and a storage component;

[0023] The conveying device includes a frame and a conveyor belt installed on the frame through a driving assembly;

[0024] The rejection device includes a fixed frame, a detector, a cylinder, and a push plate. The fixed frame is arranged on the frame, the detector is arranged inside the fixed frame, the cylinder is arranged on a side wall of the fixed frame, the output end of the cylinder passes through the side wall of the fixed frame and is connected to the push plate, and the bottom wall of the push plate is in contact with the top of the conveyor belt.

[0025] The storage assembly includes an inclined plate and a material receiving box. A discharge hole is opened on the fixed frame. One end of the inclined plate is arranged on the fixed frame, and the other end is arranged at the top opening of the material receiving box.

[0026] When the detector detects a circuit board that does not meet the standards, the conveyor belt stops driving, and the cylinder in the rejection device drives the push plate to move towards the unqualified circuit board and push the unqualified circuit board to the inclined plate outside the discharge hole. The circuit board falls into the receiving box under the action of its own gravity and the inclined plate, completing the rejection operation. The cylinder is started to move the push plate to the edge of the conveyor belt, making it difficult to affect the subsequent conveying operation of the conveyor belt; therefore, the rejection mechanism can remove the circuit boards that do not meet the standards on the conveyor belt from the surface of the conveyor belt in time, and store them through the storage component, reducing the subsequent sorting work of the circuit boards and being more convenient.

[0027] Reference Figure 1-Figure 3 A plurality of limit rods are provided on the push plate, and one end of the limit rod away from the push plate passes through the fixed frame, and the plurality of limit rods are distributed on both sides of the push plate.

[0028] The limiting rod passes through the fixing frame, so that when the push plate slides, the limiting rod is slidably mounted on the fixing frame, and the push plate is unlikely to shake, thereby improving the stability of the rejection device.

[0029] Reference Figure 2 One end of the inclined plate is arranged at the edge of the discharge port, and the other end is arranged tilted downward in the direction close to the material receiving box, and baffles are arranged on both sides of the inclined plate.

[0030] One end of the inclined plate is arranged at the edge of the discharge port to facilitate the reception of the circuit board at the discharge port. The inclined setting of the inclined plate is used to enable the circuit board on the inclined plate to slide into the storage box. The setting of the baffle is used to reduce the probability of the circuit board on the inclined plate falling out of the storage box.

[0031] Reference Figure 1-Figure 2 Two limiting mechanisms are provided on both sides of the fixed frame. The limiting mechanisms include a first motor, a drive shaft, and a limiting plate. The first motor is mounted on the fixed frame. One end of the drive shaft is connected to the output end of the first motor, and the other end is rotatably mounted on the fixed frame. The limiting plates are provided on the side walls of the drive shaft. The two limiting plates are provided on both sides of the push plate.

[0032] When the detector detects a circuit board that does not meet the standards, the conveyor belt stops, the first motor is started, the drive shaft rotates, and the two limit plates rotate in the direction close to the push plate until they are in contact with the side plates on both sides of the push plate. At this time, the bottom end of the push plate is in contact with the conveyor belt until it is in contact with each other, and the unqualified circuit board is limited between the two limit plates, which is used to reduce the probability of excessive deviation of the circuit board during the pushing process. In addition, the two limit plates are in contact with the side plates on both sides of the push plate, which can further reduce the probability of the push plate shaking during use.

[0033] Reference Figure 1-Figure 2 The driving assembly includes a second motor, multiple side plates and multiple transmission shafts. The side plates are arranged on both sides of the top of the frame. The transmission shaft is rotatably arranged between the multiple side plates. The second motor is arranged on the side plates, and the output end of the second motor is connected to the transmission shaft.

[0034] When the conveyor belt needs to be started, the second motor is started, the conveyor shaft rotates, and the conveyor belt is driven to transmit. Therefore, the drive assembly is set to drive the conveyor belt to transport the circuit board.

[0035] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
