Automatic splicing and positioning carrier for frames

Abstract

The invention discloses an automatic splicing and positioning carrier for frames. The automatic splicing and positioning carrier for frames comprises a carrying plate, wherein a plurality of splicing and positioning mechanisms are arranged on the carrying plate; each splicing and positioning mechanism comprises a pressing mechanism and a pushing mechanism; the pressing mechanisms can press adjacent frame bars; the pushing mechanisms push the adjacent frame bars to be close to one another; each pressing mechanism comprises a pneumatic toggle clamp; a group of pressing plates are arranged at the front end of each pneumatic toggle clamp; the front ends of the pressing plates are separately connected with pressure head screws capable of pressing the frame bars from above; each pushing mechanism comprises a pushing cylinder, an outer limiting block and an inner limiting block; a push rod is arranged at the front end of each pushing cylinder; each outer limiting block is arranged at the front end of the corresponding push rod; and each pushing cylinder pushes the corresponding push rod so as to drive the corresponding outer limiting block to push the two corresponding adjacent frame bars, and each outer limiting block and the corresponding inner limiting block are clamed tightly to implement tight attachment of connection positions of the two corresponding adjacent frame bars. The frame bars only need to be placed at approximate positions, automatic positioning for splicing of the frames is realized, the operation difficulty is reduced, the production efficiency is improved, the degree of automation is high, splicing and positioning of frame bars with different sizes are realized, and the universality is high.

Description

technical field [0001] The invention belongs to the technical field of automation devices, and in particular relates to an automatic splicing device suitable for welding frames such as LED lighting lamps, liquid crystal TV displays, solar silicon wafers or doors and windows. Background technique [0002] At present, the external frames used in LED lighting, LCD TV displays, solar silicon wafers or doors and windows are mostly aluminum frames, which are generally processed by manual welding or automatic welding. [0003] When welding the aluminum frame manually, the operator usually needs to complete the splicing of the adjacent aluminum strips first, and then weld the joints of the aluminum strips with the welding torch. The skill requirements are relatively high. Generally, skilled masters are required to train the newly appointed operators for a period of time before they can take up their posts. The long training time cannot meet the needs of the enterprise for the candid...

Problems solved by technology

[0003] When manually welding the aluminum frame, the operator usually needs to complete the splicing of the adjacent aluminum strips first, and then weld the joint of the aluminum strips with a welding torch. The operator will damage the aluminum strips if he is not careful during the welding process. Therefore, the manual welding frame technology The skill requirements are relatively high. Generally, skilled masters are required to train new operators for a period of time before they can take up the job. The long training time cannot meet the company's needs for the candidates to take up the job immediately; moreover, some toxic Substances, such as: acetaldehyde, rosin acid, sulfide, isocyanate, nitrogen oxides, etc., and fly in the air, these toxic substances are easy to invade the human liver, lungs, cardiovascular and blood through the respiratory tract, welding process α, β, and γ rays will also be produced in the welding process, and these radioactive substances will accumulate in the body in a small amount. Therefore, the toxic and radioactive substances produced during the manual welding process may endanger the health of the operators and cause some occupational diseases of the operators. occur

The above situation usually leads to a shortage of operators in this position of the enterprise, and the production capacity of the enterprise is tight

At the same time, the manual welding operation is cumbersome, the work efficiency is low, and it cannot meet the batch development trend of related products of the enterprise; the error caused by manual welding is also large, which will cause unstable product quality

[0004] Therefore, the inventor of this case and other companies have invented some automatic welding equipment, but because the splicing of aluminum frames can only be done manually, it still hinders the development of automatic welding equipment, and due to the limitation of the fixture structure, it is not suitable for different The shape or size of the workpiece is generally a special welding machine for a certain type of product. Welding different workpieces requires the use of different welding equipment or the replacement of fixtures that match the workpiece. The versatility is poor, resulting in reduced welding efficiency and increased production costs.
