DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 , the automatic pressing tool comprises a bottom plate 1 and an adjusting assembly 2 fixed on the upper surface of the bottom plate 1, the surface of the bottom plate 1 is provided with a plurality of mounting holes, the adjusting assembly 2 comprises a vertical rod 202 fixed on the upper surface of the bottom plate 1 and a first sliding block 201 vertically sliding on the surface of the vertical rod 202, the surface of the vertical rod 202 is fixedly connected with a limiting rod for preventing the first sliding block 201 from rotating, the first sliding block 201 slides on the surface of the limiting rod and the vertical rod 202, the surface of the first sliding block 201 is provided with a locking bolt, the first sliding block 201 is fixed on the surface of the vertical rod 202 through the locking bolt, the side surface of the first sliding block 201 is fixedly connected with two cross rods 204, the ends of the two cross rods 204 away from the first sliding block 201 are fixedly connected with a connecting plate, the surfaces of the two cross rods 204 are respectively horizontally slidably provided with a second sliding block 203, the surface of one of the second sliding blocks 203 is provided with a locking bolt, and the second sliding block 203 is fixed on the surface of the cross rod 204 through the locking bolt.

[0023] It can be understood that the first sliding block 201 slides on the surface of the vertical rod 202, so that the initial height of the pressing assembly 3 is adjusted, the two second sliding blocks 203 slide on the surfaces of the two cross rods 204, so that the lateral position of the pressing assembly 3 is adjusted, the plane jig 4 is adjusted to the upper side of the PCB, and the locking bolt is arranged, so that the positions of the first sliding block 201 and the second sliding block 203 are respectively fixed, and the position of the pressing assembly 3 is fixed.

[0024] Specifically, the pressing assembly 3 comprises a plurality of sliding rods 301 vertically sliding on the surfaces of the two second sliding blocks 203, the lower ends of the plurality of sliding rods 301 are fixedly connected with a mounting block 302, the lower surface of the mounting block 302 is fixedly connected with a plane jig 4 for pressing components, and the mounting block 302 is driven to lift by a driving push rod 303, the driving push rod 303 is a pneumatic cylinder, and the pneumatic cylinder is fixedly connected between the two second sliding blocks 203.

[0025] It can be understood that the push rod 303 is driven to work, so that the mounting block 302 and the plane jig 4 are moved downward, so that the plane jig 4 simultaneously presses the components, thereby avoiding missing, deviation or tilting caused by manual pressing, and improving work efficiency. Under the action of the plurality of sliding rods 301, the mounting block 302 and the plane jig 4 are kept horizontal during lifting, thereby preventing tilting and improving stability.

[0026] Specifically, the positioning rod 5 vertically slides on the surface of the second sliding block 203. The positioning rod 5 is arranged in the forward direction of the PCB. The lifting assembly 6 is arranged on the side of the mounting block 302 close to the positioning rod 5. The lifting assembly 6 comprises a connecting shaft 602 fixed on the side of the mounting block 302 close to the positioning rod 5. The lifting block 601 rotates on the surface of the connecting shaft 602. The end of the lifting block 601 close to the positioning rod 5 is inclined. The torsion spring 603 is sleeved on the surface of the connecting shaft 602. The torsion spring 603 is used to drive the lifting block 601 to keep horizontal. The stop block 604 is fixedly connected to the side of the positioning rod 5 close to the mounting block 302. The stop block 604 is arranged above the lifting block 601. The end of the stop block 604 close to the mounting block 302 is inclined. The top rod 7 is fixedly connected to the lower surface of the second sliding block 203 where the positioning rod 5 is arranged. The top rod 7 is arranged directly above the lifting block 601.

[0027] It can be understood that by arranging the positioning rod 5, when the PCB is conveyed to the lower side of the plane jig 4, the positioning rod 5 is blocked to make the PCB accurately stop below the plane jig 4, so as to achieve the purpose of accurate positioning. By arranging the lifting block 601 and the stop block 604, when the mounting block 302 drives the lifting block 601 to rise, the lifting block 601 drives the stop block 604 and the positioning rod 5 to slide upward, so that the positioning rod 5 is separated from the PCB, and the pressed PCB continues to move forward. When the lifting block 601 contacts the top rod 7, the top rod 7 pushes the lifting block 601 to rotate downward, so that the lifting block 601 is separated from the stop block 604, so that the positioning rod 5 automatically slides downward to block the PCB again. The lifting block 601 is restored to horizontal again under the action of the torsion spring 603. When the mounting block 302 drives the lifting block 601 to move downward, the lifting block 601 is rotated upward through the inclined surface, so that the lifting block 601 smoothly descends below the stop block 604, thereby facilitating the lifting of the positioning rod 5 again.

[0028] Specifically, the obstacle sensor 8 is fixedly connected to one side of the lower end of the positioning rod 5. The obstacle sensor 8 is an infrared sensor. The height of the infrared sensor is the same as the moving height of the PCB, which is used to detect the position of the PCB. The counterweight 9 is fixedly connected to the side of the positioning rod 5 away from the obstacle sensor 8.

[0029] It can be understood that when the positioning rod 5 blocks the PCB, the infrared sensor detects the PCB, so as to facilitate the cylinder to work and press the PCB, and the counterweight 9 is arranged, so as to facilitate increasing the weight of the lower end of the positioning rod 5, and the positioning rod 5 can automatically slide downward.

[0030] In the utility model, the pressing tool is fixed on the conveying line of the PCB through the bottom plate 1, the initial height of the plane jig 4 is adjusted through the sliding of the first sliding block 201 on the surface of the vertical rod 202, the horizontal position of the pressing assembly 3 and the plane jig 4 is adjusted through the sliding of the two second sliding blocks 203 on the surfaces of the two horizontal rods 204, the plane jig 4 is adjusted to the upper side of the PCB, the positions of the first sliding block 201 and the second sliding block 203 are fixed through the locking bolts, so that the position of the plane jig 4 is fixed, when the PCB is conveyed to the lower side of the plane jig 4, the PCB is accurately stopped under the plane jig 4 through the blocking of the positioning rod 5, the infrared sensor detects the PCB, the cylinder works, the driving push rod 303 works, the mounting block 302 and the plane jig 4 are driven to move downward, the plane jig 4 simultaneously presses the components, the missing, deviation or skew phenomenon caused by artificial pressing is avoided, the working efficiency is improved, after pressing, the mounting block 302 and the plane jig 4 are lifted through the driving of the driving push rod 303, when the mounting block 302 drives the lifting block 601 to lift, the lifting block 601 drives the blocking block 604 and the positioning rod 5 to slide upward, the positioning rod 5 is separated from the PCB, the pressed PCB continuously moves forward, when the lifting block 601 contacts the top rod 7, the top rod 7 drives the lifting block 601 to rotate downward, the lifting block 601 is separated from the blocking block 604, the positioning rod 5 automatically slides downward under the action of the counterweight 9 and is used for blocking the PCB again, and the lifting block 601 is restored to the horizontal position again under the action of the torsion spring 603, when the mounting block 302 drives the lifting block 601 to move downward, the lifting block 601 is rotated upward through the inclined surface, the lifting block 601 smoothly drops below the blocking block 604, and the positioning rod 5 is conveniently lifted again.
