Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1-4, the robot welding jig provided by the present invention comprises a rotary table 1, the rotary table 1 is installed on a multi-station rotary table, four stations or six stations can be used, the rotary station is the prior art, and the detailed structure thereof is not described herein, a set of fixing devices 2 is installed on the rotary table 1, the set of fixing devices 2 is distributed in an annular array with the center of circle of the rotary table 1 as the reference, i.e. four or six fixing devices 2 are installed, the fixing devices 2 include a first baffle 21, the first baffle 21 is fixedly connected to the upper side of the rotary table 1, the upper side of the rotary table 1 is further provided with a second baffle 22 parallel to the first baffle 21, one end of the upper side of each of the first baffle 21 and the second baffle 22 is fixedly connected with a positioning column 23, positioning holes on the corners of the circuit board correspond to the positioning columns 23, the circuit board, 1 upside of carousel is equipped with

spout

25, 24 sliding fit of slider connects in spout 25, spout 25 keeps away from the one end fixed connection apron 26 of first baffle 21, rotate connecting screw 27 between apron 26 and the spout 25 other end, apron 26 is passed and at end fixed connection hand wheel 28 to screw 27 one end, screw 27 rotates the back, slider 24 slides in spout 25, corresponding second baffle 22 is adjusted with first baffle 21's interval, and then the interval of two reference columns 23 changes, thereby adapt to the not circuit board of equidimension, improve the commonality.

Each fixing device 2 further comprises a pressing piece 3, each pressing piece 3 comprises two vertical plates 31, the two vertical plates 31 are parallel to the first baffle plate 21, a square guide column 32 is fixedly connected between the two vertical plates 31, the guide column 32 is slidably connected with a guide block 33, one side, close to the first baffle plate 21, of each guide block 33 is fixedly connected with two transverse plates 34, a pressure rod 35 is rotatably connected between the two transverse plates 34, a torsion spring is arranged on a rotating shaft of the pressure rod 35, one end of the torsion spring is fixedly connected with the pressure rod 35, the other end of the torsion spring is fixedly connected with the transverse plates 34, a through threaded hole is further formed in the upper side of each guide block 33, a locking bolt 4 is in threaded connection with a threaded hole, a transverse rod 5 is fixedly connected at the upper end of the locking bolt 4, a rubber pad is fixedly connected to one side, close to the first baffle plate 21, after an electronic element to be welded on a circuit board is aligned with a welding point, the pressing rod 35 is released downwards, the pressing rod 35 fixes the electronic element to be welded under the action of the torsion spring, after the electronic element is fixed, the turntable 1 rotates, the station rotates to a position right below the welding machine, the welding machine is not limited to a host machine used by an automatic tin soldering machine in Yajiang river, and a welding head of the tin soldering machine realizes the welding of the circuit board through a corresponding control program.
