Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to a glue dispensing positioning fixture. Background Art

[0002] Glue dispensing is a process that is widely used in the manufacture of electronic products. It aims to reinforce, seal and insulate electronic components to improve the product's moisture resistance, humidity resistance and thermal conductivity, thereby better protecting sensitive electronic components. The glue dispensing process mainly involves applying, encapsulating or dripping electronic glue, oil or other liquids onto the product to achieve adhesion, encapsulation, insulation and fixation.

[0031] Working principle of this utility model:

[0032] When using the positioning fixture on the dispensing machine to fix thin plate products, first apply a force to the force-applying circular plate 524 in the direction of the air supply cylinder 522. The force-applying circular plate 524 will drive the piston rod 523 to gradually enter the interior of the air supply cylinder 522. During this process, the gas in the air supply cylinder 522 will enter the interior of the airbag 512 through the connecting hose 527 and the L-shaped tube 516. As the airbag 512 gradually expands, the airbag 512 will drive the limit block 513 to move upward, and the limit block 513 will stop moving when it contacts the inner wall of the rectangular limit hole. After that, the friction force between the inner wall of the rectangular limiting hole will gradually increase. When the second strip clamp 4 cannot be easily pushed, the T-shaped locking rod 526 will be inserted into the corresponding locking hole. Then, the thin plate product can be placed between the first strip clamp 3 and the second strip clamp 4, and the clamping and positioning work can be completed by adjusting the screw 2. When the force exerted by the first strip clamp 3 on the product is too large, the limiting block 513 will disengage from the rectangular limiting hole. At this time, the product positioning is released, avoiding the occurrence of large force deformation of the product, and improving the quality of the dispensing work.
