Specific Embodiments
[0014] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.
[0015] As shown in Figure 1As shown in the figure, a new type of wire bonding tooling fixture includes a workbench 1 with a hollow interior, a cover plate 2, a bottom plate 3, and a first cylinder 4. A butting hole 5 is provided at the top of the workbench 1. The cover plate 2 is placed on the workbench 1 and located above the butting hole 5. Two butting members 6 are slidably arranged on the workbench 1, and the two butting members 6 are in relative butting with the cover plate 2. A through hole 7 that is vertically opposite and coaxial with the butting hole 5 is provided at the bottom of the workbench 1. The first cylinder 4 is located below the workbench 1, and the telescopic end of the first cylinder 4 is vertically upward and is fixedly provided with an adsorption assembly. The bottom plate 3 is placed on the adsorption assembly, and the bottom plate 3 is adapted to the butting hole 5. The adsorption assembly is used to drive the bottom plate 3 to vertically pass through the through hole 7 and be arranged in the butting hole 5. An LED substrate is butted and clamped between the cover plate 2 and the bottom plate 3. The wire bonding area of the LED substrate corresponds to the wire bonding groove of the cover plate 2. A wire bonding head 8 is provided on the workbench 1, and a plurality of support legs 9 are provided at the bottom of the workbench 1.
[0016] During the use of the present utility model, the operator makes the LED substrate be butted and clamped between the cover plate 2 and the bottom plate 3 to limit the LED substrate, so that the wire bonding head 8 has a better effect and higher precision when performing wire bonding processing on the LED substrate. At the same time, the adsorption assembly and the first cylinder 4 are used in cooperation to position and install the bottom plate 3, and two butting members 6 are also used to position and clamp the cover plate 2, with a simple structure and good effect.
[0017] As Figure 1 and Figure 3 shown, the adsorption assembly includes a positioning box 10, an air suction box 11, and an exhaust fan 12. The positioning box 10 is fixedly arranged on the telescopic end of the first cylinder 4. Two opposite positioning members 13 are fixedly arranged at the top of the positioning box 10. When the bottom plate 3 is located between the two positioning members 13 and the bottom plate 3 is arranged in the butting hole 5, both of the two positioning members 13 are in contact with the inner top wall of the workbench 1. A plurality of air suction holes 14 that are opened at the top of the positioning box 10 and communicate with the inside of the positioning box 10 are provided between the two positioning members 13. The air suction box 11 is fixedly arranged in the positioning box 10, and the top of the air suction box 11 is a grid plate 15. The grid plate 15 is in contact with the inner top wall of the positioning box 10. The exhaust fan 12 is fixedly arranged in the positioning box 10 and is located below the air suction box 11. The air outlet of the exhaust fan 12 is airtight, and an air suction pipe 16 that is conductively connected to the air suction box 11 is fixedly arranged at the air inlet of the exhaust fan 12. As Figure 1 and Figure 2As shown in the figure, two vertically downward limiting blocks 28 are fixedly arranged on the inner top wall of the workbench 1. The two limiting blocks 28 are relatively arranged on both sides of the abutting hole 5, and the two limiting blocks 28 can be abutted against the positioning box 10 relatively. First, the operator places the cover plate 2 on the positioning box 10 and makes the cover plate 2 arranged between the two positioning members 13. Then, the exhaust fan 12 is started. The air inlet of the exhaust fan 12 sucks air from the air suction box 11 through the air suction pipe 16. The air suction box 11 sucks and adsorbs the bottom of the bottom plate 3 through the grid plate 15 and the air suction holes 14 thereon. Then, the operator starts the first cylinder 4. The telescopic end of the first cylinder 4 moves vertically upward, so as to drive the positioning box 10 and the bottom plate 3 to pass through the through hole 7 and enter the interior of the workbench 1. When the positioning member 13 abuts against the inner top wall of the workbench 1, the operation of the first cylinder 4 is stopped. At this time, the bottom plate 3 is arranged in the abutting hole 5 and the top of the bottom plate 3 is horizontal with the top of the workbench 1, and the two limiting blocks 28 are both abutted against the positioning box 10. This design method is convenient for the limiting installation of the bottom plate 3, makes the abutting and supporting of the bottom plate 3 on the LED substrate more stable and accurate, and is convenient for the welding of the LED substrate.
[0018] As Figure 1 and Figure 2 shown in the figure, two second cylinders 17 with horizontally opposite telescopic ends are fixedly arranged in the workbench 1. A support rod 18 vertically upward passing through the top of the workbench 1 is fixedly arranged on the telescopic end of each second cylinder 17. The bottom parts of the two abutting members 6 are fixedly connected to the tops of the two support rods 18 passing through the top of the workbench 1 correspondingly. Two first limiting grooves 19 are formed on the workbench 1. The two first limiting grooves 19 are relatively arranged on both sides of the abutting hole 5. The two support rods 18 are respectively slidably arranged in the two first limiting grooves 19 correspondingly. As Figure 1 and Figure 2 shown in the figure, protruding bumps 26 are arranged on both opposite sides of the cover plate 2. A clamping groove 27 adapted to the bump 26 is arranged on one side of each abutting member 6 abutted against the cover plate 2. The operator places the LED substrate above the abutting hole 5, then places the cover plate 2 on the LED substrate, and then starts the two second cylinders 17 simultaneously. Each second cylinder 17 drives the support rod 18 thereon to slide relatively in the corresponding first limiting groove 19 through the telescopic end, so as to make the two abutting members 6 approach each other relatively and abut against the cover plate 2. At this time, the clamping grooves 27 on the two abutting members 6 and the two bumps 26 on the cover plate 2 are respectively clamped correspondingly. This design method is convenient for the abutting and limiting of the cover plate 2, makes the welding effect of the LED substrate more accurate, and at the same time makes the movement of the abutting member 6 more stable and can be accurately clamped with the cover plate 2.
[0019] As Figure 1 and Figure 2As shown, two third cylinders 20 with horizontal telescopic ends are fixedly installed inside the workbench 1. The telescopic ends of the third cylinders 20 are perpendicular to the telescopic ends of the second cylinders 17. Two second limiting grooves 21 are formed on the workbench 1. The two second limiting grooves 21 are relatively arranged on both sides of the abutting hole 5 and are arranged between the two first limiting grooves 19. A vertically upward connecting rod 22 is fixedly installed on the telescopic end of each third cylinder 20. The tops of the two connecting rods 22 slidably pass through the two second limiting grooves 21 correspondingly. And a abutting block 23 for abutting and positioning the LED substrate is fixedly installed at the top of each connecting rod 22. The two abutting blocks 23 are relatively arranged on both sides of the cover plate 2, and the two abutting blocks 23 are respectively arranged right below the two abutting members 6 one by one. When it is necessary to limit and weld the LED substrate, the operator places the LED substrate between the two abutting blocks 23, and then starts the two third cylinders 20 simultaneously. The two third cylinders 20 drive the connecting rods 22 to move in the corresponding second limiting grooves 21 through their telescopic ends, so as to drive the LED substrate to move along the direction of the second limiting grooves 21 through the two abutting blocks 23. When the LED substrate is located on the abutting hole 5, the operation of the two third cylinders 20 is stopped. This design method is convenient for the movement and transportation of the LED substrate, makes the accuracy of the LED substrate during welding processing more accurate, and has a simple structure and is easy to operate.
[0020] As Figure 1 and Figure 2 shown, two fourth cylinders 24 with vertically upward telescopic ends are fixedly installed on the workbench 1. A connecting plate 25 is fixedly installed on the telescopic ends of the two fourth cylinders 24 simultaneously. A welding head 8 is fixedly installed at the bottom of the connecting plate 25. The welding head 8 is opposite to the abutting hole 5. When it is necessary to weld and process the LED substrate, the operator starts the welding head 8 and the two fourth cylinders 24 respectively. The telescopic ends of the two fourth cylinders 24 drive the welding head 8 to move vertically downward through the connecting plate 25, so as to weld and process the area to be welded of the LED substrate through the welding wire groove of the cover plate 2. This design method is convenient for wire welding of the LED substrate, has a simple structure and is easy to operate.
[0021] Working principle:
[0022] First, the operator places the cover plate 2 on the positioning box 10 and positions the cover plate 2 between the two positioning members 13. Then, the exhaust fan 12 is started. The air inlet of the exhaust fan 12 sucks air from the air suction box 11 through the exhaust duct 16. The air suction box 11 sucks and adsorbs the bottom of the bottom plate 3 through the grid plate 15 and the air suction holes 14 thereon. Next, the operator starts the first cylinder 4. The telescopic end of the first cylinder 4 moves vertically upward, thereby driving the positioning box 10 and the bottom plate 3 through the through hole 7 into the interior of the workbench 1. When the positioning member 13 abuts against the inner top wall of the workbench 1, the operation of the first cylinder 4 is stopped. At this time, the bottom plate 3 is arranged in the abutting hole 5 and the top of the bottom plate 3 is flush with the top of the workbench 1, and both limiting blocks 28 abut against the positioning box 10.
[0023] Next, the operator places the LED substrate to be welded and processed between the two abutting blocks 23, and simultaneously starts the two third cylinders 20. Both of the two third cylinders 20 drive the connecting rod 22 to move in the corresponding second limiting groove 21 through their telescopic ends, thereby driving the LED substrate to move along the direction of the second limiting groove 21 through the two abutting blocks 23. When the LED substrate is arranged on the abutting hole 5, the operation of the two third cylinders 20 is stopped.
[0024] After that, the cover plate is placed on the LED substrate, and then the two second cylinders 17 are simultaneously started. Each second cylinder 17 drives the support rod 18 thereon to slide relatively in the corresponding first limiting groove 19 through its telescopic end, so that the two abutting members 6 approach each other relatively and abut against the cover plate 2. At this time, the clamping grooves 27 on the two abutting members 6 and the two protrusions 26 on the cover plate 2 are respectively clamped in one-to-one correspondence.
[0025] Next, the operator starts the welding head 8 and the two fourth cylinders 24 respectively. The telescopic ends of the two fourth cylinders 24 drive the welding head 8 to move vertically downward through the connecting plate 25, so that the welding head 8 welds the area to be welded of the LED substrate through the welding wire groove of the cover plate 2.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
