Operation device and assembly line for automatically assembling upper and lower covers of shielding cases on line

Abstract

The invention discloses an operation device for automatically assembling upper and lower covers of shielding cases on line. The operation device comprises a horizontal movement assembly, a cover buckling assembly and a taking and placing assembly. The cover buckling assembly and the taking and placing assembly are installed on the horizontal movement assembly and driven by the horizontal movement assembly to move back and forth horizontally. An assembly line is built through operation devices and comprises multiple carrying trolleys, the operation devices are correspondingly arranged on one sides of the carrying trolleys needing to operate products, and all movements of the operation devices are controlled by a control system. The operation device has the advantages that the upper and lower covers of the shielding cases can be automatically assembled in parallel on line, so that labor intensity is relieved, production efficiency is greatly improved, production quality is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of assembly lines, in particular to an operating device and an assembly line for automatically assembling the upper and lower covers of a shielding cover online. Background technique [0002] When designing and producing electronic products, parts with special requirements are often designed as a separate module, and the module exchanges signals with other circuits through pin headers, connectors or connections. Some modules require higher sensitivity or generate large interference signals, so they need to be wrapped with a metal cavity to achieve signal shielding, so as to isolate the interference caused by external signals or prevent their own signals from interfering with other circuits. Normal work, such as high-sensitivity receiving module, front-end filter, front-end amplifier, signal source, signal modulator, etc. [0003] For larger modules, shielding covers made of metal cast aluminum cavities or C...

AI Technical Summary

Problems solved by technology

[0013] 2. High labor skill requirements

[0014] Due to the full manual operation, the working hours are long and the movements are complicated, so there are quite high requirements for the hand-eye coordination and movement accuracy of the workers. Generally, a new operator needs a week of practice to meet the production efficiency requirements.

[0015] 3. The surface is prone to fingerprints and sweat stains

[0016] Due to the long working hours and high labor intensity, the operator's hands are prone to sweating, resulting in the contamination of the product surface with sweat stains, so gloves or finger cots must be worn for operation

However, wearing gloves or finger cots not only seriously affects the operation efficiency, but also aggravates the phenomenon of finger sweating. Sweat seeps out through the gloves or finger cots. When pressing the cover, it is easy to form pollution on the surface of the module product. The subsequent process requires Set up a special person to check and clean

[0017] 4. It is easy to appear that the four corners or the partial fastening are not in place, resulting in warping

[0018] During the manual buckling operation, due to the limited pressing area of ​​the fingers at one time, or the fatigue caused by long-term pressing, it is easy to happen that a certain corner is not pressed in place during the operation, resulting in quality problems

[0019] 5. It is easy to have the upper and lower covers buckled upside down or wrong

[0020] A single station needs to buckle the upper cover and the lower cover. Due to the small difference in the shape of the upper and lower covers, it is easy to make mistakes, such as buckling the upper cover to the position of the lower cover or buckling the lower cover to the position of the upper cover, resulting in production rework

In order to prevent mistakes, if it is designed that one person buckles the cover and another person buckles the cover, a single module product will go through two hands and two assembly line pick-and-place operations, and the production efficiency will be reduced by at least 20%.

[0021] 6. The operation efficiency is low and the labor demand is high

Compared with method 1, each person has 2,500 pcs in a single class, although the force required for fastening is small due to the use of jigs, but the quantity increases by 60%, that is, the number of pick-and-place actions will increase by 60%, and the labor intensity is high.

[0026] 2. High labor skill requirements

[0027] For the first fully manual operation station, the working hours are long and the movements are complicated, so there are quite high requirements for the hand-eye coordination and movement accuracy of the workers. Generally, a new operator needs a week of practice to meet the production efficiency requirements. ;For the second station using semi-automatic jigs, it is required to be able to accurately place the pre-fastened product into the jig, start the jig operation, and require high hand-eye coordination, otherwise personal injury may occur

[0028] 3. It is easy to have the upper and lower covers buckled upside down or wrong

[0029] The first manual station needs to fasten the upper cover and the lower cover. Due to the small difference in the shape of the upper and lower covers, it is easy to make mistakes, such as buckling the upper cover to the position of the lower cover or buckling the lower cover to the position of the upper cover, resulting in rework in production

[0030] 4. The operation efficiency is very low, and the labor demand is high

[0034] Two semi-automatic stations form a group, and each product requires the cooperation of two people to complete. Each group needs to complete 4,000 products in a single shift, that is, each station needs to complete the operation of 4,000 products in a single shift. Compared with method 1, each person 2,500 pcs in a single shift, although the force required for fastening is small due to the use of jigs to assist, but if the quantity increases by 60%, the number of pick-and-place actions will increase by 60%, which is labor-intensive

[0035] 2. High labor skill requirements

[0037] 3. The operation efficiency is low and the labor demand is high

[0038] Each product needs to go through two stations to complete, and it needs to go through two pick-and-place operations of the product from the assembly line. At the same time, because it is an offline operation, the production efficiency is very low
