Problems solved by technology

In the process of processing waste circuit boards, various electronic components need to be disassembled and separated. Such components are generally difficult to handle. Failure to disassemble and sort them will affect the recycling process and the recycling quality of other metals.
Disassembly is divided into manual disassembly and mechanical disassembly. When disassembling various components on the discarded circuit board, most of the old discarded circuit boards are manually loaded, so there will be some safety and efficiency issues.
[0003] After investigation, it was found that the invention titled "A processing equipment and method for non-destructive dismantling of waste circuit boards" (Chinese Patent: Application No. 200810224887.7) proposed a loading method for loading cards, which required manual loading Waste circuit boards, low efficiency, only suitable for small-scale production, can not meet the operation capacity of large-scale processing waste circuit boards

Embodiment 1

[0034] First put the unloaded clamp 3 into the clamp slide rail of the clamp feeding end 11 on the upper part of the automatic feeding frame 1, and the movement of the conveying mechanism 4 moves the clamping groove of the telescopic clamping mechanism 5 to the clamping groove column 37 of the clamping device 3 Directly below, the slot inside the retractable slot mechanism 3 lifts up the slot column 37 that clamps the clamp 3, the conveying mechanism 4 drives the clamp 3 to be transported to the top of the clamp opening and closing mechanism 2 and then stops, and the clamp opening and closing mechanism 2 pushes the clamp 3 is opened, and the discarded TV circuit board to be loaded is loaded into the clamp 3, the clamp opening and closing mechanism 2 is closed, and the conveying mechanism 4 drives the clamp 3 to convey forward, and an automatic feeding is completed. After testing, the discarded TV circuit board is It can automatically feed 3000 pieces.

Embodiment 2

[0036] First put the unloaded clamp 3 into the clamp slide rail of the clamp feeding end 11 on the upper part of the automatic feeding frame 1, and the conveying mechanism 4 starts to move the clamping slot of the telescopic clamping mechanism 5 to the clamping slot column 37 of the clamping device 3 Directly below, the slot inside the retractable slot mechanism 5 lifts up the slot column 37 that clamps the clamp 3, and the conveying mechanism 4 drives the clamp 3 to be transported directly above the clamp opening and closing mechanism 2 and then stops, and the clamp opening and closing mechanism 2 pushes the clamp 3 is opened, and the discarded tablet computer circuit board to be loaded is loaded into the fixture 3, the fixture opening and closing mechanism 2 is closed, and the conveying mechanism drives the fixture 3 to convey forward, and an automatic feeding is completed. After testing, the discarded tablet computer circuit board can be used every hour. Automatic feeding 36...

Embodiment 3

[0038] First put the unloaded clamp 3 into the clamp slide rail of the clamp feeding end 11 on the top of the automatic feeding frame 1, and the conveying mechanism 4 starts to move the clamping groove of the telescopic clamping groove mechanism 5 to the clamping groove column 37 of the clamping device. Below, the slot inside the retractable slot mechanism 5 lifts up the slot column 37 that clamps the clamp 3, and the conveying mechanism 4 drives the clamp 3 to be transported to the top of the clamp opening and closing mechanism 2 and then stops, and the clamp opening and closing mechanism 2 pushes the clamp 3 Open it, load the discarded mobile phone circuit boards to be loaded into the clamp 3, the clamp opening and closing mechanism 2 is closed, and the conveying mechanism 4 drives the clamp 3 forward to complete one automatic feeding. After testing, the discarded mobile phone circuit boards can be automatically loaded every hour. The material is 5400 yuan.

Abstract

The invention discloses an automatic feeding clamp for waste circuit board desoldering equipment and a method. The automatic feeding clamp comprises an automatic feeding machine frame, clamp sliding rails are arranged on the two sides of the automatic feeding machine frame, a clamp body is installed on the clamp sliding rails, a conveying mechanism is arranged on the lower sides of the clamp sliding rails on the two sides, telescopic clamping groove mechanisms are fixed to moving parts at the two ends of the conveying mechanism, and the telescopic clamping groove mechanisms are matched with protruding clamping groove columns on the two sides of the clamp body, so that the conveying mechanism can drive the clamp body to convey waste circuit boards; and the moving position of the clamp body can be controlled through the telescopic clamping groove mechanisms on the moving parts of the conveying mechanism, a clamp opening and closing mechanism is fixed to the plane of the inner side of the automatic feeding machine frame, the clamp opening and closing mechanism is used for opening or closing the clamp body, and when the clamp body is opened, the waste circuit boards are put inwards. According to the automatic feeding clamp, the clamping distance of the clamp is adjustable, the clamp can be suitable for waste circuit boards of various models and sizes, and rapid and efficient automatic feeding of the waste circuit board desoldering equipment is achieved.

Description

technical field [0001] The invention relates to the technical field of recycling and processing waste circuit boards, in particular to an automatic feeding fixture and method for waste circuit board desoldering equipment. Background technique [0002] Discarded circuit boards are chemically and physically different from other forms of industrial solid waste, which contain valuable and dangerous substances that require special handling and recycling to avoid environmental pollution and harmful effects on human health. How to efficiently recycle valuable substances in waste circuit boards is the focus of current research. At present, the main research and development direction is focused on the separation of metals and non-metals in waste circuit boards, and the resource utilization of separated metals and non-metals. For the resource recovery technology of waste circuit boards, the commonly used treatment methods are: mechanical treatment, hydrometallurgy, heat treatment tec...
