BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] See also Figure 1 The utility model provides a PCB fixture conveying mechanism which is easy to maintain, comprising: a conveyor belt 1, a plurality of temporary storage bins 2 and an update bin 3 arranged above the conveyor belt 1, wherein the temporary storage bin 2 and the update bin 3 are arranged above the conveyor belt 1 at intervals, the temporary storage bin 2 is empty, and the update bin 3 is filled with replaceable PCB fixtures.

[0015] During operation, the PCB fixture is transported by the conveyor belt 1 to meet the supply of PCB fixtures and the transportation of PCB boards in the production and processing of PCB boards. When the PCB fixture fails or is damaged, the PCB fixture is transported along the conveyor belt 1, and when the PCB fixture moves to the bottom of the temporary storage bin 2, the PCB fixture with the failure or damage is sent to the temporary storage bin 2, and the intact PCB fixture is lowered through the update bin 3, so that the PCB fixture can be replaced without stopping the conveyor belt 1, which not only ensures the replacement of the PCB fixture, but also avoids the loss of time cost and production cost caused by downtime.

[0016] Several lifting mechanisms are arranged below the conveyor belt 1. The lifting mechanisms are arranged at corresponding positions of the temporary storage warehouse 2 and the update warehouse 3. The lifting mechanisms include: a lifting drive mechanism and a lifting plate arranged on the output end of the lifting drive mechanism. In some embodiments, the lifting mechanism corresponding to the temporary storage warehouse 2 is arranged below the conveyor belt 1 to lift the abnormal PCB fixture to the temporary storage warehouse 2; the lifting mechanism corresponding to the update warehouse 3 is arranged in the update warehouse 3 to lower the replaced PCB fixture and place it on the conveyor belt 1. The lifting plate is lifted up by the lifting drive mechanism, so that the PCB fixture with faults or damage is lifted upward to the temporary storage warehouse, and the problematic PCB fixture is transferred to the temporary storage warehouse 2 for placement. At the same time, the lifting plate is lowered by the lifting drive mechanism, so that the PCB fixture stored in the update warehouse 3 is lowered and placed on the conveyor belt 1, which meets the demand for PCB fixture replacement and avoids the PCB fixture falling directly from the update warehouse 3 and causing damage.

[0017] In some embodiments, the lifting drive mechanism uses a cylinder or an electric screw slide. The PCB fixture is lifted up by the cylinder, or the electric screw slide is used to meet the lifting and moving requirements of the PCB fixture, and the stroke is stable, and installation, debugging and maintenance operations are easy to perform.

[0018] In some embodiments, a blocking mechanism is provided at the rear end of the conveyor belt 1 corresponding to the lifting mechanism, and the blocking mechanism includes: a blocking lifting cylinder and a blocking block provided on the output end of the blocking lifting cylinder. When the conveyor belt 1 moves the PCB fixture to be replaced to the bottom of the temporary storage bin, the blocking lifting cylinder is started to push the blocking block upward, so that the blocking block moves to the feeding surface of the conveyor belt, thereby providing a limit for the PCB fixture on the conveyor belt 1, so as to facilitate the PCB board to be replaced to be moved to the temporary storage bin 2 for placement through the lifting mechanism.

[0019] In some embodiments, a protective door is provided at the bottom of the temporary storage bin 2 and the update bin 3, respectively. The protective door adopts a double-door structure, and the door leaves on both sides of the double-door structure are respectively connected to a door leaf driving mechanism. When the lifting drive mechanism lifts the lifting plate upward, the door leaf driving mechanism drives the door leaves of the double-door structure to open, thereby facilitating the lifting plate to enter the temporary storage bin 2 or the update bin 3 to replace the PCB fixture.

[0020] In some embodiments, a bottom support mechanism is respectively provided on both sides of the temporary storage bin 2 and the update bin 3, and the bottom support mechanism includes: a bottom support cylinder and a bottom support block provided at the output end of the bottom support cylinder, and the bottom support cylinders on both sides drive the bottom support block to move toward the center direction in the horizontal direction.

[0021] When the lifting drive mechanism moves the PCB fixture to the temporary storage bin 2, the bottom support cylinder retracts, and the bottom support block provides a clearance for the PCB fixture to be sent in. When the PCB fixture moves to a height higher than the upper surface of the bottom support block driven by the lifting drive mechanism, the bottom support cylinder pushes the bottom support block out, so that the bottom support block is cushioned under the PCB fixture. Then the lifting drive mechanism is reset, so that the lifting plate is separated from the PCB fixture and moves to the initial position, while the PCB is kept on the bottom support block for placement, waiting for the operator to take out the defective PCB fixture for processing.

[0022] When the lifting mechanism takes the PCB fixture from the update bin 3, the lifting drive mechanism drives the lifting plate to move upward, thereby lifting the PCB fixture placed on the bottom support block. Then the bottom support cylinder retracts, driving the bottom support block to avoid the position, and then the lifting drive mechanism moves downward to take the PCB board out of the update bin 3.

[0023] In some embodiments, both sides of the temporary storage bin 2 and the update bin 3 are provided with material-taking sliding doors. When a defective PCB fixture is sent into the temporary storage bin 2, the material-taking sliding door can be opened to take out the PCB fixture in the temporary storage bin 2, so as to facilitate the repair or replacement of the damaged PCB fixture. After the PCB fixture in the update bin 3 is sent to the conveyor belt 1 for transportation, another set of PCB fixtures can be placed in the update bin 3 by opening the material-taking sliding door, so as to facilitate the subsequent replacement of the PCB fixture.

[0024] In summary, the utility model transports PCB fixtures through a conveyor belt, thereby meeting the supply of PCB fixtures and the transportation of PCB boards in the production and processing process of PCB boards. When a PCB fixture fails or is damaged, the PCB fixture is transported along the conveyor belt, and when the PCB fixture moves to the bottom of the temporary storage bin, the PCB fixture with a failure or damage is sent to the temporary storage bin, and the intact PCB fixture is lowered through the update bin, thereby realizing the replacement of PCB fixtures without stopping the conveyor belt, which not only ensures the replacement of PCB fixtures, but also avoids the loss of time cost and production cost caused by downtime.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
