[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The pin connector press-fit device provides two technical solutions:

[0028] like Figures 1-6 The first embodiment is shown: it includes a support table 1, an electrical box 2, a press-fit assembly 3 and a servo slide 4, and a terminal block is installed in the servo slide 4, and a feeding mechanism is provided between the press-fit assembly 3 and the servo slide 4, and the feeding mechanism includes:

[0029] The continuous loading component 5 is used for continuously loading pin needles. The continuous loading component 5 includes two left and right U-shaped frames 51. The interiors of the two U-shaped frames 51 are both rotatably connected with pulleys 52. The two pulleys 52 are connected through a belt 53. A plurality of fixed components 55 are equidistantly fixedly connected to the surface of the belt 53. A fixed plate 56 is fixedly connected between the two U-shaped frames 51. A plurality of support wheels 57 are rotatably connected to the back of the fixed plate 56 at equal distances.

[0030] The fixing assembly 55 includes a fixing plate 551, which is fixed on the surface of the belt 53. A support plate 552 is fixedly connected to the front of the fixing plate 551. A plurality of needle grooves 553 matching the size of the pin needles are equidistantly provided inside the support plate 552. An extension ball groove 554 is provided on the left side of the inner wall of the needle groove 553. A steel ball 555 is installed inside the extension ball groove 554. A limit spring 556 is fixedly connected between the inner wall of the extension ball groove 554 and the steel ball 555.

[0031] When loading the pins, the pins are continuously fed to the press-fitting position through the continuous loading component 5, so that the loading can be carried out continuously, which is conducive to rapid press-fitting, and the pins are pre-fixed through the fixing component 55, which improves the working efficiency of the device.

[0032] As Figure 2 and 3 Figure 2 shows the second embodiment. The main difference from the first embodiment is that the adjustment component 6 is used to adjust the alignment between the fixed component 55 and the terminal block. The adjustment component 6 includes an L-shaped frame 61 which is fixedly connected to the front surfaces of two U-shaped frames 51. A T-shaped slide bar 62 is fixedly connected to the front surface of the support table 1. The L-shaped frame 61 is slidably connected to the surface of the T-shaped slide bar 62. A lead screw 63 is threadedly connected to the front surface of the support table 1, and the L-shaped frame 61 is threadedly connected to the surface of the lead screw 63.

[0033] When the continuous feeding component 5 is in use, the alignment between the fixed component 55 and the terminal block is adjusted by the adjustment component 6, so as to ensure the accuracy of the position during press-fitting.

[0034] During use, the pin is placed into the pin slot 553. After the pin is placed, the pin contacts the steel ball 555, and the steel ball 555 presses the pin under the action of the limiting spring 556, thereby fixing the position of the pin. The stepping motor 54 is started to make the pulley 52 rotate, and through the action of the pulley 53, another pulley 52 rotates, so that the fixed component 55 moves. The fixed component 55 moves and aligns with the terminal block on the servo slide 4. At this time, the press-fitting component 3 is started for press-fitting. In addition, when the alignment between the pin slot 553 in the fixed component 55 and the terminal block changes, the lead screw 63 is rotated to make the L-shaped frame 61 move. The L-shaped frame 61 moves and drives the continuous feeding component 5 to move, so that the fixed component 55 is aligned with the terminal block.
