When in use, the displacement in the X direction is guaranteed by a limit seat arranged on the table 6. It also includes a belt track section 3 arranged on the table 6, and the belt track section 3 includes two belt tracks arranged in parallel, and the width between the belt tracks is adjustable and the center distance is unchanged. The jig clamped by the cylinder clamping part 2 is placed on the jig positioning mechanism. The jig full of plates flows out of the device through the belt operation. It includes a jig box 4 placed on the table 6, and the jig box 4 contains the jig, and the jig clamping part takes out the jig from the jig box 4. It includes a pin belt track, and the pin belt track 5 includes two parallel arranged ones, and the end of the pin belt track 5 is connected to the push-down section 1.

[0028] like Figure 2 As shown, the jig 9 is a tubular structure, and the jig lower surface and two side surfaces are distributed with equidistant circular holes, which reduce the weight of the jig and allow hot air to circulate during reflow. The first hole and the fifth hole on the lower surface of the jig are used as positioning holes and are used in conjunction with the jig positioning mechanism.

[0029] like Figure 3 As shown, the pushing and unloading part 1 includes two symmetrically arranged parts, which are arranged on both sides of the pin belt track 5 through the mounting plate 109. The pushing and unloading part 1 includes a first cylinder 102, which is mounted on the mounting plate 109, and provides thrust in the horizontal direction. The first cylinder 102 includes a piston rod end, which is connected to the push rod connecting block 104 by bolts. The push rod connecting block 104 is provided with a through hole connected to the piston rod end. It includes a copper sleeve 108 arranged on the mounting plate 109, and the copper sleeve 108 is connected to a first guide column 101 parallel to the first cylinder 102. The diameter of the first guide column 101 is 6 mm, and the first guide column 101 is used in conjunction with the copper sleeve, and the first guide column 101 reciprocates in the inner hole of the copper sleeve 108. The first guide column 101 is used for guidance to ensure the position of the push rod connecting block 104.

[0030] The push rod connection block 104 is provided with a U-shaped groove, and a swinging swing rod 107 is provided in the U-shaped groove. The push rod connection block 104 is also provided with a through hole, and the through hole passes through both sides of the U-shaped groove.

[0035] The swing rod 107 is a Z-shaped structural member and is provided with a 6mm eccentric through hole. When in use, the threaded cylinder 106 supplies air, so that the piston rod extends, and the end of the upper surface of the swing rod 107 is thrust, thereby driving the swing rod 107 to rotate counterclockwise around the first guide column 101. When the threaded cylinder 106 stops supplying air, the piston rod retracts, and the swing rod 107 rotates clockwise around the first guide column 101 under the action of gravity to reset until the end of the upper surface of the swing rod 107 abuts against the piston rod.

[0036] like Figure 4 As shown, in the jig clamping jaw part 2, a base plate 202, two supporting upright plates 201 and a reinforcing plate 203 are combined and connected to form a mounting seat. The two supporting upright plates 201 are arranged on both sides of the base plate. The upper surface of the supporting upright plate 202 is connected with a reinforcing plate 203, and the lower surface of the reinforcing plate 203 is fixedly connected to the supporting upright plate 202. The mounting seat is mounted on the upper surface of the table 6 through the base plate.

[0037] A Y-axis module 204 is installed on the upper surface of the reinforcing plate. The Y-axis module 204 is used in conjunction with a stepping motor, and the Y-axis module 204 performs reciprocating motion.

[0038] The lower surface of the connecting plate 206 is provided with a step groove, and the step groove is installed to connect the vertical plate 205. During assembly, the step groove is used to achieve alignment. The connecting plate 206 is installed on the slider of the Y-axis module. The connecting plate 206 is also installed with a solenoid valve 207, and the solenoid valve 207 provides power to the finger cylinder 211.

[0039] The connecting vertical plate 205 is connected to a back plate 208, and the back plate 208 is connected to a Z-direction module 209, and the Z-direction module 209 is arranged on the left side of the back plate 208. The back plate 208 prevents the sensor 305 protruding from the Z-direction module 209 from interfering with the connecting vertical plate 205.

[0040] The air gripper connecting plate 210 is L-shaped and has a large chamfer. One end of the air gripper connecting plate 210 is mounted on the slider of the Z-axis module, and the other end of the air gripper connecting plate 210 is mounted with a finger cylinder 211. The large chamfer avoids the danger of sharp angles. The finger cylinder 211 is a through-hole mounting type.

[0041] The finger cylinder 211 is connected to a clamping jaw, and the clamping jaw is provided with two symmetrically arranged clamping jaws 212. The length of the clamping jaw 212 ranges from 50 to 100 mm, preferably 80 mm, and the ratio of the length of the clamping jaw 212 to the length of the metalworking tool is 1:5. The side of the clamping jaw 212 is provided with a side groove, and the width of the side groove is the same as the width of the clamping jaw, and the side groove is connected and fixed to the finger cylinder 211. The bottom of the clamping jaw 212 is provided with a chamfer, and the chamfer extends into the middle gap to play a guiding role when clamping the high-temperature metalworking tool.

[0042] The side of the clamping jaw 212 is provided with a V-shaped groove, and the V-shaped groove fixes the metallurgy to prevent it from falling during transfer. The depth groove, chamfer and V-shaped groove of each clamping jaw 212 are located on the same side and face outward. When the clamping jaw of the finger cylinder 211 is opened, the high-temperature metallurgy is clamped, and when the clamping jaw of the finger cylinder 211 is closed, the high-temperature metallurgy is placed.

[0043] like Figure 5 As shown, the table top 6 is provided with a limiting seat surrounded by a plurality of limiting blocks 8, and the jig box 4 is placed in the limiting seat to ensure the position consistency of the jig box 4 each time.

[0044] In another embodiment, Figure 6As shown, the belt track structure is provided with a fixed side 314 and a supporting side 312, and the fixed side 314 and the supporting side 312 are installed on the table 6. The two ends of the third guide column 309 are respectively connected to the fixed side 314 and the supporting side 312, and the third guide column 309 passes through the fixed side 314. The fixed side 314 is provided with four through holes, and the four through holes respectively pass through the third guide column 309, the long hexagonal rod 315 and the lead screw 322. The fixed side 314 is provided with a step hole, and the supporting side is provided with two similar step holes, and the step hole is installed with a bearing 321, and the bearing supports the two ends of the hexagonal rod.

[0045] The adjustable side 313 is provided with a branch line bearing, a bearing 321 and a lead screw nut 307. An L-shaped belt limiting plate 304 is included, and the belt limiting plate 304 covers the belt supporting plate 303, and has higher strength and is not easy to deform.

[0046] When in use, the hexagonal rod is used as a driving shaft, and a sleeve 317 with an inner hexagonal shape and an outer circle is provided between the driving wheel 320 and the hexagonal rod. The belt support plate 303 supports the belt 319 to prevent the belt 319 from sagging. The belt limit plate limits the jig to prevent the jig from deviating when the belt is running. The sensor 305 detects whether the jig flows out of the jig positioning mechanism.

[0047] The shaft sleeve 317 passes through the driving wheel 320, the washer 318 and the bearing 321. The driving wheel 320 is fixed to the shaft sleeve 317 by screws, and the washer 318 is located between the bearing 321 and the driving wheel 320. The washer 318 limits the position of the driving wheel 320 for easy installation. One end of the shaft sleeve 317 is provided with a retaining ring groove, and a retaining ring 324 is installed in the retaining ring groove. The washer and the retaining ring 324 together make the shaft sleeve and the adjustable side 313 form a whole. When in use, the lead screw 322 rotates, driving the lead screw nut 307 to move, and driving the adjustable side 313 to move together, thereby driving the shaft sleeve to reciprocate along the hexagonal rod.

[0048] When in use, the two tracks are driven by motors 311 respectively, the front belt track is driven by the long hexagonal rod 315, and the rear belt track is driven by the short hexagonal rod 310.

[0049] In other embodiments, a positioning fixture structure 7 is included, such as Figure 7As shown, the positioning jig structure 7 includes an upper plate 701 and a lower plate 706. A linear bearing 308 is arranged on the upper surface of the table 6, and a seventh cylinder 704 is arranged on the lower surface of the table 6. The seventh guide column reciprocates along the linear bearing 308 in the vertical direction. The seventh cylinder 704 is fixed to the lower plate 706 through a floating joint 705. The upper plate 701 and the lower plate 706 are fixedly connected by the seventh guide column. The upper plate supports the jig, and the upper surface of the upper plate abuts against the lower surface of the jig. Two positioning pins 710 are fixedly arranged on the upper surface of the upper plate. The seventh cylinder 704 is connected to two displacement sensors 709, and the displacement sensors 709 detect whether the seventh cylinder 704 is retracted and in place.

[0050] The edge of the positioning pin 710 is provided with a large chamfer. The middle of the positioning pin 710 is provided with an intermediate waist-shaped hole. The chamfer of the positioning pin 710 guides the jig when the jig is slightly deformed, thereby improving the repeatability of the jig placement position. The intermediate waist-shaped hole adjusts the installation position of the positioning pin 710 and ultimately adjusts the placement position of the jig. This ensures that the jig entrance and the pin belt track 55 are accurately docked without misalignment. This ensures that the workpiece enters the jig accurately and without obstacles.

[0051] When in use, the seventh cylinder extends downward, driving the lower plate to move downward, and at the same time driving the upper plate to move downward, so that the positioning pin 710 is separated from the positioning hole of the high-temperature metallurgy, and the high-temperature metallurgy falls to the belt track. The seventh cylinder retracts upward, and finally drives the upper plate to move upward, so that the upper surface of the upper plate is higher than the upper surface of the belt.

[0052] In other embodiments, the belt track structure is provided with an adjustable mechanism to adjust the track width. The two track adjustment sides are located on the same side, and after the width is adjusted, the center distance of the two tracks remains unchanged. The width adjustment is achieved through the same lead screw, and the two lead screw nuts 307 are respectively installed on the two adjustable sides 313. The lead screw fixed end 302 is locked by hand to prevent the lead screw from rotating and fix the track width.

[0053] When in use, the adjustable side 313, the fixed side and the supporting side are all plate-like structures, and the adjustable side 313 can move between the supporting side and the fixed side. The adjustable mechanism includes two adjustable sides 313 located on both sides of the belt track, and the width between the two tracks is adjusted by the adjustable sides 313 in the two adjustable mechanisms.

[0054] When in use, the ceramic light source is located on the pin insertion belt track after the pin is inserted. When the ceramic light source moves on the pin insertion belt track to the pushing and unloading part, the swing rod in the pushing and unloading part drives the push rod to push the ceramic light source out of the pin insertion belt track and fall into the belt track part. Then the jig clamping claw part clamps the ceramic light source from the belt track part, and finally moves the ceramic light source to the jig box on the other side of the belt track part.

[0055] The jig jaws are moved in height and vertically to the belt processing part by the Z-axis module and the Y-axis module. In other embodiments, the Z-axis module and the Y-axis module are driven by at least one of a cylinder, a slider, a motor, and a telescopic rod.

[0056] In other embodiments, a nut 103 is disposed at the end of the first cylinder 102 , and the driving wheel is connected to a tensioning wheel 306 .

[0057] These modifications or improvements made on the basis of the present utility model without departing from the spirit of the present utility model shall all fall within the scope of protection required by the present utility model.
