Description

Technical Field

[0001] The present application relates to the technical field of patch conveying equipment, and in particular to a patch conveying mechanism. Background Art

[0002] SMT stands for surface mount technology, the most popular technique and process in the electronics assembly industry. It refers to the series of processes performed on PCBs. The steps are: solder paste printing, component placement, reflow soldering, AOI (Automated Optical Inspection) inspection, repair, and depaneling. After reflow soldering, the PCB is conveyed to the AOI (Automated Optical Inspection) equipment, where it is inspected for defects.

[0003] When conveying patches, workers need to manually place multiple patches one by one on the conveyor belt for conveying. The operation is cumbersome and time-consuming, which increases the workload and energy consumption of workers and affects work efficiency. Therefore, an improvement is now made to a patch conveying mechanism. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a patch conveying mechanism that overcomes the shortcomings of the existing technology and aims to solve the problem that when conveying patches, staff need to manually place multiple patches one by one on the conveyor belt for conveyance, which is cumbersome and troublesome, increases the workload and energy consumption of staff, and affects work efficiency.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a patch conveying mechanism, comprising a conveying table, a conveyor belt is provided inside the conveying table, a loading table is provided on one side of the conveying table, a storage box is fixedly installed on one side of the upper surface of the loading table, an automatic loading unit is fixedly connected to the interior of the storage box, a patch assembly is placed on the top of the automatic loading unit, the patch assembly is composed of a plurality of stacked patches, a robotic arm is fixedly installed on the upper surface of the loading table on one side of the storage box, and an adsorption clamping unit is fixedly installed on one end of the robotic arm.

[0006] By adopting the above technical solution, the patches can be adsorbed and fixed through the cooperation between the robotic arm and the adsorption clamping unit, so that the patches in the storage box can be placed one by one on the conveyor belt, and the patches are transported by the conveyor belt. The position of the patch assembly is adjusted by the automatic loading unit to ensure that the top patch in the patch assembly is always in the same horizontal plane with the top of the storage box, which facilitates the adsorption and clamping unit to adsorb and fix the patches. Multiple patches can be placed one by one on the conveyor belt without manual operation by the staff, which not only reduces the workload of the staff, but also improves work efficiency.

[0007] As a preferred technical solution of the present application, the adsorption and clamping unit includes a mounting plate fixedly connected to the robotic arm, a vacuum pump is fixedly installed on the top of the mounting plate, and a suction cup connected to the vacuum pump is fixedly connected to the bottom of the mounting plate.

[0008] By adopting the above technical solution, the air at the suction cup is extracted by a vacuum pump, so that the patch can be adsorbed and fixed, which facilitates subsequent transfer work.

[0009] As a preferred technical solution of the present application, the automatic loading unit includes a carrier plate, the bottom of which is fixedly connected to the inner bottom wall of the storage box through two return springs, the top of the carrier plate is in contact with the bottom of the patch assembly, and the elastic force of the return spring is balanced with the gravity of the patch assembly.

[0010] By adopting the above technical solution, when the top patch in the patch assembly is removed, the return spring will push the carrier plate upward through its elastic force, ensuring that the top patch in the patch assembly can be accurately placed in the specified position, thereby realizing automatic loading.

[0011] As a preferred technical solution of the present application, a support seat is fixedly installed on the inner bottom wall of the storage box between the two return springs, and the top of the support seat is in contact with the bottom of the loading plate.

[0012] By adopting the above technical solution, the carrier plate is supported by the support seat, which avoids the reset spring being crushed due to placing too many patches on the carrier plate, thereby ensuring the normal operation of the automatic loading unit.

[0013] As a preferred technical solution of the present application, four limit blocks evenly distributed in a linear array are fixedly connected to the upper surface of the carrier plate, and four plug-in slots evenly distributed in a linear array are opened through the upper surface of the carrier plate, and the limit blocks are adapted to the plug-in slots.

[0014] By adopting the above technical solution, the carrier plate is limited by the cooperation between the limiting block and the plug-in slot, ensuring that the carrier plate can always move up and down along the specified trajectory.

[0015] As a preferred technical solution of the present application, the four limiting blocks are combined to form a placement slot that matches the external dimensions of the patch component, and the top of the limiting block is on the same horizontal plane as the top of the storage box.

[0016] By adopting the above technical solution, through the cooperation between the four limiting blocks, the patch component can be accurately positioned, making it convenient for the adsorption and clamping unit to adsorb and fix the patch.

[0017] As a preferred technical solution of the present application, the outer dimensions of the loading plate are adapted to the inner space of the storage box, and positioning blocks are fixedly connected to the inner walls of both sides of the storage box near the upper end.

[0018] By adopting the above technical solution, the positioning block is provided to block the carrier plate, thereby preventing the carrier plate from escaping from the interior of the storage box.

[0019] As a preferred technical solution of the present application, the outer surface of the conveyor belt is provided with a plurality of friction lines.

[0020] By adopting the above technical solution, the friction pattern is designed to increase the friction between the conveyor belt and the patch to prevent the patch from sliding during transportation.

[0021] Beneficial effects of this application:

[0022] In the utility model, the patches can be adsorbed and fixed through the cooperation between the mechanical arm and the adsorption clamping unit, so that the patches in the storage box can be placed one by one on the conveyor belt, and the conveyor belt is used to convey the patches. The position of the patch assembly is adjusted by the automatic loading unit to ensure that the top patch in the patch assembly is always in the same horizontal plane with the top of the storage box, which is convenient for the adsorption clamping unit to adsorb and fix the patches. Multiple patches can be placed one by one on the conveyor belt without manual operation by the staff, which not only reduces the workload of the staff but also improves work efficiency.
