DETAILED DESCRIPTION

[0024] 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. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Please refer to Figure 1 Figure 5 As shown in the figure, the embodiment provides a modular SMT patch jig convenient to replace, which comprises a base 1 and further comprises:

[0026] Supporting plates 4 are symmetrically arranged above the base 1, and each of the opposite sides of the two supporting plates 4 is provided with a moving plate 6, and each of the opposite sides of the two moving plates 6 is rotatably connected with a rotating rod 24, and each of the other ends of the two rotating rods 24 is fixedly connected with a fixed plate 7, and the two fixed plates 7 are provided with a patch body 8 therebetween;

[0027] An adjusting assembly is arranged outside the supporting plate 4;

[0028] A fixing assembly is symmetrically arranged on the opposite sides of the two fixed plates 7;

[0029] A turnover assembly is arranged on the upper surface of the moving plate 6.

[0030] The above working principle: when the patch body 8 needs to be fixed, only the distance between the two fixed plates 7 is adjusted through the adjusting assembly according to the specifications of the patch body 8, and then the patch body 8 is placed between the two fixed plates 7, and then the patch body 8 is fixed through the fixing assembly, so that different specifications of the patch body 8 can be fixed conveniently and effectively, and the practicability of the jig is improved. When the other side of the patch body 8 needs to be processed, the patch body 8 can be turned over conveniently through the turnover assembly, without the need for workers to repeatedly manually turn over and re-fix the patch body 8, which effectively improves the processing efficiency of the patch body 8, reduces the work burden of the workers, further improves the practicability of the jig as a whole, and saves time and effort.

[0031] ​In order to effectively adjust the height position of the fixed assembly, the upper surface of the base 1 is symmetrically provided with a connecting sleeve plate 2, the inside of the two connecting sleeve plates 2 is provided with a movable plate 3, the upper surface of the two movable plates 3 is respectively fixedly connected with the bottom of the two supporting plates 4, and the two movable plates 3 and the connecting sleeve plate 2 are fixedly connected through bolts. When it is necessary to adjust the height position of the fixed assembly, the bolts are first unscrewed, and then the movable plate 3 is pulled out in the inside of the connecting sleeve plate 2. When the movable plate 3 drives the supporting plate 4 to move to the appropriate height position, the connecting sleeve plate 2 and the movable plate 3 are fixed by bolts. At this time, the height position of the fixed assembly can be adjusted, so that the flip of the patch body 8 cannot occur.

[0032] Considering that the distance between the two fixed plates 7 needs to be adjusted when fixing different specifications of the patch body 8, the adjusting assembly comprises a mounting block 5 fixedly connected outside the supporting plate 4, a slide rod 13 fixedly connected in the inside of the mounting block 5, a resisting plate 14 provided in the inside of the mounting block 5, a guide groove for the slide rod 13 to move being formed in the inside of the resisting plate 14, a return spring 15 being sleeved outside the slide rod 13, the return spring 15 abutting between the resisting plate 14 and the mounting block 5, a side plate 16 being symmetrically provided on one side of the resisting plate 14, a pull ring being fixedly connected outside every two side plates 16, a connecting rod 17 being symmetrically provided on the other side of the resisting plate 14, and the other end of every two connecting rods 17 being fixedly connected with the outside of the two moving plates 6. When it is necessary to fix the patch body 8, the pull ring is first pulled. At this time, the pull ring drives the side plate 16 to move synchronously, the side plate 16 drives the resisting plate 14 to move synchronously outside the slide rod 13, the resisting plate 14 drives the connecting rod 17 to move synchronously in the process of moving, the connecting rod 17 drives the moving plate 6 and the fixed plate 7 to move synchronously, and then the patch body 8 is placed between the two fixed plates 7, and the pull ring is released. At this time, the return spring 15 resets, drives the resisting plate 14 to move synchronously, the resisting plate 14 drives the fixed plate 7 to move synchronously, and the fixed plate 7 drives the fixed assembly to move synchronously. When the inner wall of the fixed assembly abuts the outside of the patch body 8, the patch body 8 can be fixed for the first time, different specifications of the patch body 8 can be effectively fixed, and the practicability of the jig as a whole is effectively improved.

[0033] In order to further enhance the fixed effect of the patch body 8, the fixed assembly includes the U-shaped plate 9 symmetrically arranged on the opposite side of the two fixed plates 7, the upper surface of the U-shaped plate 9 is provided with a threaded hole for the screw rod 10 to move, the top end of the screw rod 10 is fixedly connected with the knob 12, and the bottom end of the screw rod 10 is fixedly connected with the abutting disc 11. When the inner wall of the U-shaped plate 9 abuts against the outer portion of the patch body 8, the knob 12 is rotated again, at this time the knob 12 drives the screw rod 10 to rotate synchronously, and the screw rod 10 drives the abutting disc 11 to move synchronously. When the bottom of the abutting disc 11 abuts against the upper surface of the patch body 8, the fixed effect of the patch body 8 can be further enhanced through the cooperation between the abutting disc 11 and the U-shaped plate 9.

[0034] In order to effectively protect the patch body 8, the inner wall of the U-shaped plate 9 and the bottom of the abutting disc 11 are both attached with rubber protective pads. When the U-shaped plate 9 and the abutting disc 11 fix the patch body 8, the pressure generated during the fixing process may cause damage to the patch body 8. At this time, the rubber protective pads can effectively buffer the pressure, thereby effectively protecting the patch body 8.

[0035] In addition, in order to effectively flip the patch body 8, the flipping assembly includes the support rods 18 symmetrically arranged on the upper surface of the moving plate 6, the top end of every two support rods 18 is fixedly connected with the fixed block 19, the inside of the fixed block 19 is provided with the fixed rod 20, one end of the fixed rod 20 is fixedly connected with the outer plate 23, the outside of the fixed rod 20 is fixedly connected with the sliding plate 21, the outside of the fixed rod 20 is sleeved with the abutting spring 22, the abutting spring 22 abuts between the sliding plate 21 and the fixed block 19, the outside of the rotating rod 24 is fixedly connected with the rotating disc 25, the inside of the rotating disc 25 is provided with the guide groove for the fixed rod 20 to move. When it is needed to flip the patch body 8, the outer plate 23 is pulled first, at this time the outer plate 23 drives the fixed rod 20 to move synchronously, the fixed rod 20 drives the sliding plate 21 to move synchronously. In the process of the sliding plate 21 moving, the abutting spring 22 is extruded. When the fixed rod 20 is separated from the guide groove in the inside of the rotating disc 25, the patch body 8 is then pushed, at this time the patch body 8 drives the fixed assembly and the fixed plate 7 to rotate synchronously, the fixed plate 7 drives the rotating rod 24 to rotate synchronously, the rotating rod 24 drives the rotating disc 25 to rotate synchronously. When the other side of the patch body 8 faces upward, the outer plate 23 is then released, at this time the abutting spring 22 resets, drives the sliding plate 21 and the fixed rod 20 to move synchronously. When the fixed rod 20 is inserted into the guide groove in the inside of the rotating disc 25, the rotating disc 25 and the fixed plate 7 can be locked, at this time the patch body 8 can be flipped without the need for the staff to manually flip and re-fix the patch body 8, thereby effectively improving the processing efficiency of the patch body 8, reducing the work burden of the staff, and further improving the practicability of the jig as a whole.
