Problems solved by technology

The cover is usually removed by remelting the welding seam with the roller electrode and then separating the cover plate and the pipe seat. However, due to the small thickness of the parallel seam welded cover plate, it is difficult to remove and the pipe seat is easy to be damaged. Burrs may appear on the surface of the pipe seat after the cover is removed. It is necessary to mechanically polish and flatten the tube base before repackaging, the process is cumbersome, the efficiency is low, and the quality such as flatness is difficult to control

Embodiment 1

[0025] Such as Figure 1 to Figure 2 As shown, a parallel seam welding rework plugging device includes a box body 1, and a workbench 2 is movable inside the box body. The workbench 2 can rotate and move up and down. Electric telescoping rod is realized. Workbench 2 is provided with a number of clamping seats arranged regularly. The clamping seats are used for clamping reworked products. The horizontal clamping seats form a horizontal clamping seat group, and the vertical clamping seats form a vertical clamping seat group. The number of seat groups is equal.

[0026] A liquid application mechanism is provided in the cabinet 1 to move left and right through a shift mechanism, which is used for applying glue to the reworked product and cleaning the surface of the reworked product after the glue coating is completed. Specifically, the liquid application mechanism includes a mounting plate 8 and several liquid application parts arranged thereon. The liquid application parts inclu...

Embodiment 2

[0033] Such as figure 1 and image 3 As shown, in order to speed up the curing speed of the anaerobic adhesive, in the present embodiment, an auxiliary curing mechanism is movable through the displacement mechanism in the box body 1. The auxiliary curing mechanism includes an air inlet shell 15 and an air outlet shell 16 arranged up and down. The box body 1 is provided with an air inlet and an air outlet, and the air inlet shell 15 and the air outlet shell 16 are respectively provided with an air inlet hole 19 and an air outlet hole 20, and the air inlet hole 19 and the air outlet hole 20 are respectively connected to the air inlet by a telescopic hose And the air outlet, the inner wall of the top of the air inlet shell 15 is provided with several stoppers 14 downwards, the number and position of the stoppers 14 are matched with the clamping seat on the workbench 2, the stoppers 14 protrude through the air outlet shell 16, and the stoppers The outside of the block 14 is provi...

Abstract

The invention discloses a parallel seam welding repairing and plugging device. The parallel seam welding repairing and plugging device comprises a box, wherein a workbench is movably arranged in the box; the workbench can rotate and move up and down; a plurality of holders are arranged on the workbench; a liquid coating mechanism is arranged in the box in a leftward / rightward moving manner througha shifting mechanism; the liquid coating mechanism comprises a mounting plate and a plurality of liquid coating parts which are arranged on the mounting plate; each liquid coating part comprises a liquid storage chamber and two liquid draining heads; and the two liquid draining heads communicate with each liquid storage chamber respectively. During application of the parallel seam welding repairing and plugging device, reprocessed products with an airtightness problem are coated and plugged with an anaerobic adhesive without removal of a cover plate for rewelding, so that the repairing and reworking difficulty and cost are lowered. Moreover, residual adhesive on the reprocessed products and the liquid draining heads can be removed. Meanwhile, curing of the anaerobic adhesive is accelerated, and the repairing efficiency is improved.

Description

technical field [0001] The invention relates to the field of parallel seam welding of electronic packaging, in particular to a repair and plugging device for parallel seam welding. Background technique [0002] Electronic packaging, in short, is to enclose electronic components, assembled and electrically interconnected device chips and related functional devices and circuits into a special shell, which plays a role in placing, fixing, sealing, protecting chips and enhancing heat conduction. The role of performance, and it is also a bridge between the internal world of the chip and the external circuit. The contacts on the chip are connected to the pins of the package shell with wires, and these pins are connected to other devices through the wires on the printed circuit board. The airtightness of packaging is one of the main assessment indicators. The significance of airtight packaging is to isolate the devices in the package from the external environment and prevent harmfu...
