Detailed Description

As shown in fig. 1 to 4, a needle head includes a rectangular sleeve 1, end plates 10 are respectively disposed at upper and lower ends of the rectangular sleeve 1, a rectangular hole 11 is disposed on each side wall of the rectangular sleeve 1, a driving source 2 is mounted on the end plate 10 located at the upper end, four clamping portions 3 are mounted at a movable end of the driving source 2, the clamping portions 3 are respectively disposed on each side wall of the rectangular sleeve 1, a push rod is disposed at the movable end of the driving source 2, the push rod penetrates through the end plate 10 located at the upper end, when the needle is clamped, the movable end of the driving source 2 moves upward, so that the push rod is far away from the end plate 10 located at the upper end, and the clamping portions 3 clamp the needle; when the pin is inserted, the movable end of the driving source 2 moves downward to make the clamping part 3 cancel the clamping of the pin, and acts on the upper end of the pin through the ejector rod to make the pin move downward.

In order to facilitate the transfer operation of the contact pins, the contact pins are generally arranged on a three-dimensional moving system, and the contact pins are transferred from a storage position to the position right above a mold through the three-dimensional moving system, so that the automatic transfer and insertion operation of the contact pins are facilitated.

Wherein, when inserting the contact pin and establishing, three-dimensional moving system shifts the contact pin head to the contact pin and deposits directly over, drives clamping part 3 through driving source 2 and carries out the centre gripping to the contact pin after the contact pin centre gripping is accomplished, shifts the contact pin to the mould directly over through three-dimensional moving system, and later cancels the centre gripping to the contact pin earlier through driving source 2, makes the contact pin downstream under the promotion of driving source 2 after that to insert the contact pin and establish on the mould.

The driving source 2 comprises a plurality of connecting rods 20 mounted on an end plate 10 at the upper end, a cylinder 21 is mounted at the upper end of the connecting rods 20, a movable plate 22 is mounted at the movable end of the cylinder 21, an overhanging support plate 23 is arranged on each side wall of the movable plate 22, and a push rod is mounted on the movable plate 22.

This driving source 2 makes clamping part 3 accomplish the centre gripping of contact pin or remove the centre gripping of disappearing through single power and cylinder 21 driven mode to when inserting the establishment through the ejector pin, make the contact pin downstream, and accomplish inserting of contact pin and establish the operation, thereby improved the efficiency and the effect of contact pin.

The clamping part 3 comprises a concave connecting plate 30 arranged at the outer side end of the overhanging support plate 23, a connecting lower plate 31 is arranged at the lower end of the concave connecting plate 30, a T-shaped part 32 is arranged at the inner side end of the connecting lower plate 31, a guide sleeve 33 is sleeved on the T-shaped part 32, the guide sleeve 33 is arranged on the outer wall of the rectangular sleeve 1, an L-shaped part 34 is arranged at the outer side end of the connecting lower plate 31, an inclined plane 340 is formed at the lower end bending part of the L-shaped part 34, the lower end of the inclined plane 340 inclines inwards, a clamping plate 38 penetrates through the rectangular hole 11, outer plates 37 are arranged at the upper end and the lower end of the clamping plate 38, spring pins 35 are respectively arranged at the two ends of each outer plate 37 in a penetrating mode, the spring pins 35 are all arranged on the rectangular sleeve 1, springs 36 are sleeved at the inner side ends of the spring pins 35, the springs 36 are located at the inner sides of the outer plates 37, overhanging plates 39 are arranged on the outer wall of the clamping plate 38, clamping plates 39 are tightly attached to the inner wall of the L-shaped part 34, clamping plates 38 are provided with clamping arc grooves 380, and anti-skid rubber pads are arranged on the outer sides of the clamping arc grooves 380, and the overhanging plate 39 are in an arc structure.

Since unclamping of the gripping section 3 is the reverse operation of gripping, the gripping operation of the gripping section 3 is described in principle in this embodiment, and it can be known how the gripping section 3 performs the gripping operation of canceling the pin.

When the pin is clamped by the clamping part 3, the pin passes through the end plate 11 at the lower end, then each L-shaped piece 34 is driven by the cylinder 21 to move along the vertical direction of the guide sleeve 33, the upward movement of the L-shaped piece 34 acts on the outer side end of the outward extending plate 39 through the inclined surface 340 at the bent part of the L-shaped piece, so that the outward extending plate 39 drives the clamping plate 38 to move inwards, the clamping operation of the pin is completed through the clamping plate 38, and when the pin is clamped, the spring 36 is also compressed, and the compressed spring 36 facilitates the outward movement of the clamping plate 38 when the clamping is cancelled.

Wherein, the contact area of grip block 38 and contact pin has been improved in the setting of centre gripping arc groove 380, and then has improved the centre gripping effect, simultaneously for improving the centre gripping effect, still set up corresponding anti-skidding rubber pad in centre gripping arc groove 380.

Wherein, the outer side end of the overhanging plate 39 is set to be an arc structure, which reduces the contact surface between the overhanging plate 39 and the L-shaped member 34, thereby improving the flexibility when clamping or cancelling the clamping.
