Optionally, the automated crimping modules 10 are symmetrically disposed on at least two sides of the crimping station 20.

Please refer to fig. 5 and 6, which are schematic structural views of the automatic crimping module 10. The automatic crimping module 10 comprises a crimping cylinder 11, a mounting seat 12, a pressing block 13, a driving rotating shaft 14 and a sleeve shaft 15; the crimping cylinder 11 and the pressing block 13 are respectively installed on the installation base 12, one end of the pressing block 13 is hinged to the piston rod 112 of the crimping cylinder 11 through the driving rotating shaft 14, the pressing block 13 is provided with a kidney-shaped groove 132, the sleeve shaft 15 penetrates through the kidney-shaped groove 132 and is installed on the installation base 12, and the shape of the kidney-shaped groove 132 enables the other end of the pressing block 13 to be pressed down or opened when one end of the pressing block 13 moves up and down along with the piston rod 112.

One end of the pressing block 13 protrudes out of the pressing head 131 capable of applying downward pressure, and the other end of the pressing block 13 is provided with a driving shaft mounting hole 133 for the driving shaft 14 to pass through.

The mount 12 includes a horizontally disposed cylinder mount 121 and a briquette mount 122 connected to one side of the cylinder mount 121. The cylinder body 111 of the pressure welding cylinder 11 is fixed on the cylinder mounting part 121, and the piston rod 112 passes through a piston rod hole 1211 formed on the cylinder mounting part 121; both ends of the quill 15 are mounted in shaft holes 1221 formed in the compact mounting portion 122.

The sleeve shaft 15 includes a fixed shaft 151 and a sleeve 152 sleeved outside the fixed shaft 151, two ends of the fixed shaft 151 are fixed on the mounting base 12, and the sleeve 152 is in clearance fit with the fixed shaft 151. When the kidney-shaped groove 132 of the pressing block 13 moves relative to the sleeve shaft 15, the sleeve 152 can form rolling contact with the inner wall of the kidney-shaped groove 132 in the kidney-shaped groove 132, so that the movement is smoother.

The working principle of the automatic crimping module 10 is as follows: when the air pipe joint 113 of the pressure welding air cylinder 11 is ventilated, the air cylinder piston rod 112 connected to the cylinder body 111 is lifted along with the air cylinder piston rod, the pressing block 13 is driven to rotate around the driving rotating shaft 25, and the pressing block 13 slides around the sleeve shaft 15 under the constraint of the middle kidney-shaped groove 132. Due to the design of the imitated movement track of the kidney-shaped groove 132, the pressing head 131 of the pressing block 13 can be opened and closed at a large angle.

The automatic crimping module 10 utilizes a smaller pressing block structure to realize a larger opening and closing angle, so that the product carrier is very convenient to take and place.

Referring to fig. 4, the pressing station 20 includes a fixed base plate 21 and a floating plate 22 for carrying a product carrier 30.

In the illustrated embodiment, two press grooves 32 are formed on the long sides of the product carrier 30. The pad point of the electrical socket 33 of the PCB board at the bottom of the product carrier 30 matches with the electrical connector 25, so that the product to be tested placed on the product carrier 30 is conducted with the electrical signal, and the test is performed.

The working principle of the automatic crimping mechanism of the product carrier is as follows: the product carrier 30 with the product is placed on the floating plate 22 and is positioned by the positioning guide posts 24; the air source of the air pipe confluence plate 27 enables the piston rods 112 of the crimping cylinders 11 of the four automatic crimping modules 10 on the automatic crimping mechanism of the product carrier to descend, and the pressing block 13 is driven by the piston rods 112 to rotate around the driving rotating shaft 14 and descend simultaneously, and slides around the sleeve shaft 15 under the constraint of the kidney-shaped groove 132, so that the pressing head 131 falls onto the product carrier 30, and the product carrier 30 is pressed downwards; the pad point of the electrical interface 33 of the PCB board at the bottom of the product carrier 30 contacts the electrical connector 25, so that the electrical connector 25 connected with the adapting PCB 26 is in signal conduction, and the product on the product carrier 30 is lighted for testing.
