The first driving member 30 is disposed on the frame 10, the pressing assembly 40 includes a base 41 and a pressing head 42, the pressing head 42 is mounted on the base 41, and the pressing portion 421 of the pressing head 42 protrudes out of the base 41 and is located above the carrier 20. Specifically, an end of the pressing head 42 away from the base 41 is bent downward to form the pressing portion 421, so as to shorten a distance from the pressing portion 421 to the welding station 21. The output end of the first driving member 30 is connected to the base 41, and when the first driving member 30 acts, the base 41 is driven to move along the vertical direction, and at this time, the whole pressing assembly 40 synchronously moves along the vertical direction. When the first driving element 30 drives the base 41 to move vertically downward, the pressing portion 421 moves vertically downward synchronously to press and fix the flexible circuit board 300 on the soldering station 21 of the carrier 20, so that an automatic soldering machine (not shown) can perform an automatic soldering operation on the flexible circuit board 300 on the soldering station 21; when the first driving member 30 drives the base 41 to move vertically upward after the soldering is completed, the pressing portion 421 moves vertically upward synchronously to release the pressing on the flexible circuit board 300, so as to take out the flexible circuit board 300.
It should be noted that the driving stroke of the first driving member 30 is set according to the distance between the pressing portion 421 and the soldering station 21, so that the first driving member 30 can complete the pressing of the flexible circuit board 300 with a single stroke.
Referring to fig. 2-6, in order to avoid damage to the flexible circuit board 300 during the pressing process of the pressing portion 421, the pressing assembly 40 of the embodiment further includes a buffer seat 43 and a seat cover 44, the buffer seat 43 is mounted on the base 41, the seat cover 44 covers the buffer seat 43 and forms an installation groove 45 together with the buffer seat 43, and the pressing head 42 is vertically adjustable and mounted in the installation groove 45, so that the pressing head 42 can perform vertical fine adjustment, the pressing portion 421 is conveniently positioned on the flexible circuit board 300, and excessive impact on the flexible circuit board 300 when the pressing portion 421 is directly pressed can be avoided, thereby effectively reducing damage to the flexible circuit board 300 caused by impact.
Specifically, the pressing assembly 40 further includes an elastic member 46, the elastic member 46 is a spring, and the elastic member 46 is compressed between the pressing head 42 and the base 41, so that the pressing head 42 always has a tendency to move away from the base 41 in the vertical direction. When the pressing portion 421 presses on the flexible circuit board 300, the elastic member 46 buffers the pressing of the pressing portion 421 on the flexible circuit board 300. Further, the buffer seat 43 is provided with a first groove 431, the pressure head 42 is provided with a second groove 422 corresponding to the first groove 431, and when the pressure head 42 is installed in the installation groove 45, the elastic member 46 is compressed and limited between the first groove 431 and the second groove 422. The elastic member 46 of the present embodiment is a spring, but the elastic member 46 may also be made of a material having elastic properties, such as elastic plastic, and the specific type of the elastic member 46 is not limited herein.
At the moment when the pressing portion 421 contacts the flexible circuit board 300, since the elastic member 46 of the pressing portion 421 has a floating supporting function on the pressing head 42, the pressing portion 421 can be pressed on the flexible circuit board 300 in a buffering manner, so that excessive impact on the flexible circuit board 300 caused by direct pressing is avoided, and damage to the flexible circuit board 300 caused by impact is effectively reduced. In addition, because there is a slight difference between the distance between the soldering position of the different flexible circuit boards 300 and the stitching portion 421, at this time, the pressing head 42 can make fine adjustment in the up-down direction for stitching different flexible circuit boards 300, so that the soldering jig 100 for flexible circuit boards of this embodiment can stitch different types of flexible circuit boards 300 to meet the soldering requirements of different flexible circuit boards 300.

Because the limit screw 48 is limited in the limit hole 423 to move, the seat cover 44 and the cushion seat 43 are synchronously limited in the limited stroke of the limit hole 423 to move. When the limit screw 48 is respectively connected with the seat cover 44 and the buffer seat 43, the buffer sleeve 49 is located in the limit hole 423, when the seat cover 44 and the buffer seat 43 are synchronously limited in the limited stroke of the limit hole 423, the buffer sleeve 49 indirectly buffers the collision between the limit screw 48 and the limit hole 423, and the limit screw 48 is prevented from forming direct rigid impact on the limit hole 423.
Preferably, the diameter of the limiting hole 423 is larger than the diameter of the buffer sleeve 49, at this time, the difference between the diameters of the buffer sleeve 49 and the limiting hole 423 is the adjustable distance of the pressure head 42 along the horizontal direction, and at this time, the driving stroke of the second driving member 47 is the difference between the diameters of the buffer sleeve 49 and the limiting hole 423. When the second driving member 47 acts, the seat cover 44 and the buffer seat 43 are driven to synchronously move along the horizontal direction, and at this time, the pressure head 42 can generate displacement with a diameter difference stroke in the horizontal direction relative to the seat cover 44 and the buffer seat 43, so that the adjustment of the pressure head 42 in the horizontal direction is realized.
