[0020] Preferably, in order to facilitate positioning, a positioning hole 21 is provided on both sides of the upper surface of the unloading plate 17, positioning rods 22 cooperating with the positioning holes 21 are provided on both sides of the lower surface of the loading plate 10, a pressure sensor 30 is provided at the bottom of the positioning rod 22, and an electromagnet 29 is provided in the upper clamping hole 11.

[0021] Preferably, in order to achieve a guiding effect and avoid positional displacement during movement, two sliders 23 are fixed on both sides of the rear of the lifting frame 8, and two linear guide rails 24 are arranged at intervals at the front end of the frame 1. The sliders 23 are slidably connected to the linear guide rails 24. In this embodiment, four sliders 23 distributed in pairs are added to the rear of the lifting frame 8, and linear guide rails 24 cooperating with the sliders 23 are fixed on the frame 1, so that when the lifting frame 8 moves up and down with the screw slide 7, there will be no problem of positional displacement, which will ultimately affect the clamping effect of the needle row below.

[0022] The specific working principle of this equipment is as follows: first install this equipment to the side of the pin row installation equipment, ensure that the loading plate 10 is aligned with the connector on the pin row installation equipment, and the height of the connector placement table on the pin row installation equipment must be lower than the height of the unloading plate 17, and the unloading plate 17 is located at the output port of the vibrating discharge tray, the vibrating discharge tray vibrates and discharges, inserts the row pins into the lower clamping holes 18, and clamps the row pins through the spring clamp 20 below, and in order to ensure that multiple pins can be inserted at the same time, multiple vibrating discharge trays can be equipped, and the vibrating discharge trays are flush and aligned with the lower clamping holes 18 on the same straight line to achieve simultaneous insertion of multiple pins, for example, the lower clamping holes 18 of the first row are inserted with pins at the same time, and then the cylinder 2 12 is driven to work, and the transverse frame 13 moves horizontally to allow the second batch of lower clamping holes 18 to be inserted with pins at the same time until all are inserted. After completion, the cylinder 12 is reset first, and then the cylinder 12 continues to work to move the unloading plate 17 horizontally to the bottom of the loading plate 10, and then the motor 2 is driven to work, driving the transmission screw 3 to rotate, so that the screw slide 7 moves down to ensure that the row of needles is inserted into the upper clamping hole 11, until the positioning rod 22 is inserted into the positioning hole 21, and the pressure sensor 30 senses the signal, and the motor 2 stops working. At this time, the electromagnet 29 is energized to attract the row of needles, and then the motor 2 is reset, so that all the row of needles are inserted on the unloading plate 17, and then the unloading plate 17 is moved down to the connector placement table of the needle installation equipment. Under the action of pressure, the row of needles is inserted into the connector on the connector placement table to complete the row of needles installation, the electromagnet 29 loses power, and the above operation is repeated. Therefore, the present structural setting can realize rapid loading of the row of needles and improve work efficiency. Embodiment 2
