Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

1-2, the bearing tool for welding pins of a circuit board comprises a bottom plate 1, a cover plate 2 and a sliding block 3, wherein the cover plate 2 is hinged on the bottom plate 1, a plurality of stations 11 for placing the circuit board are arranged on the bottom plate 1 in an array manner, welding holes 21 are formed in the cover plate 2, and the positions of the welding holes 21 correspond to the positions 11; the worker assembles the pins and the circuit board and then places them into the station 11, and then covers the cover plate 2 over the circuit board to fix the circuit board in the station 11. One end of pin is supported in the bottom of station 11, makes circuit board and pin closely laminate through apron 2, and then effectively prevents to bear the weight of the frock and jump out station 11 when removing the circuit board. The sliding blocks 3 are arranged on two sides of the bottom plate 1 in a sliding manner so as to change the position of the sliding blocks 3; the sliding block 3 is provided with a first magnet 4, the cover plate 2 is provided with a second magnet 5, and the magnetism of the opposite surface of the first magnet 4 and the second magnet 5 is opposite; when the cover plate 2 is covered on the bottom plate 1, the first magnet 4 corresponds to the second magnet 5 in position. The cover plate 2 and the bottom plate 1 are locked by the attraction of the magnets.

In an embodiment, as shown in fig. 1-2, sliding parts 12 are concavely arranged on two sides of the bottom plate 1, a sliding groove 13 is arranged in the sliding part 12, and the sliding block 3 is slidably connected with the sliding groove 13. Preferably, the sliding groove is a dovetail groove. The slider 3 is hidden in the sliding portion 12 by the sliding portion 12. The protruding part of the bearing tool is reduced, and the influence on the loading of the bearing tool into the welding machine is avoided.

In one embodiment, as shown in fig. 1-2, the locked position of the cover plate 2 is located near the bottom of the sliding portion 12, and the unlocked position of the cover plate 2 is located away from the sliding portion 12; that is, when the cover plate is covered, the slider 3 moves to the bottom of the sliding portion 12; when the cover plate 2 needs to be opened, the slider 3 moves to an end away from the sliding portion. As shown in the figure, when the cover plate 2 is unlocked, a gap is formed between the slider 3 and the bottom of the sliding portion 12, after the worker drives the slider 3 to move from the locking position to the unlocking position, the first magnet 4 and the second magnet 5 are dislocated, the two magnets are not attractive, the base 1 has self weight and keeps static, and the cover plate 2 can be opened by lifting the cover plate 2 upwards by fingers.

In the above embodiment, as shown in fig. 1-2, in order to facilitate driving the slider from the locked position to the unlocked position, the side edge of the slider 3 is recessed with a grip portion 31 allowing the insertion of a finger.

In one embodiment, as shown in fig. 1-2, the weld aperture 21 tapers in size from top to bottom. Because the welding head of the welding mechanism has a certain volume, the operation space is increased by increasing the size of the upper end of the welding port 21, and the welding hole is prevented from affecting the normal use of the welding head.

In one embodiment, as shown in fig. 1-2, the pinch portions 14 are recessed on the upper and lower sides of the station 11. So as to facilitate the taking and placing of the circuit board.

When the utility model is used, as shown in fig. 1-2, circuit boards are placed in the stations 11 one by one, after the cover plate 2 is covered, the sliding block 3 is moved to a locking position, and the first magnet 4 and the second magnet 5 are attracted to each other to complete locking. When the welding is completed, the cover plate 2 needs to be opened, the bearing tool is placed on a tabletop, the thumb acts on the end part of the bottom plate, and the forefinger is inserted into the holding part 31 to drive the sliding block 3 to move towards the unlocking position, so that the first magnet 4 and the second magnet 5 are dislocated and are in contact with the locking of the cover plate 2, and at the moment, the forefinger can easily pick up the cover plate 2 upwards.

The foregoing is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model; modifications and equivalent substitutions are intended to be included in the scope of the claims without departing from the spirit and scope of the present utility model.
