Description

Technical Field

[0001] The utility model relates to the technical field of glue coating devices, in particular to a chip gold wire glue coating device. Background Technique

[0002] A chip is a device of an integrated circuit, usually a small flat piece made of semiconductor material, on which electronic components such as transistors, resistors, capacitors, etc. can be integrated, and specific functions can be realized through circuit connections. Glue coating treatment of its gold wire is one of the processing techniques.

[0003] In order to improve the efficiency of glue coating on chip gold wires, many improvements have been made to the chip gold wire glue coating device in the prior art. For example, the patent with the patent publication number CN220919746U discloses a chip gold wire glue coating device, which includes: a base; a plurality of fixing frames, and a plurality of the fixing frames are all arranged above the base. A circuit board can be placed in the fixing frame, and a chip is provided on the circuit board. A gold wire is welded and installed between the chip and the circuit board; a glue coating mechanism, which is arranged on the base and is used for coating glue on the gold wire; a fixing mechanism, which is arranged on the base and is used for fixing the circuit board and the chip. The chip gold wire glue coating device provided by this utility model has the advantages of being able to limit the flow range of the colloid, enabling the colloid to fully wrap the gold wire, avoiding the continuous outward flow of the colloid, and improving the glue coating efficiency.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In the above comparative document, the circuit board is placed in the fixing frame, and the chip gold wire on the circuit board is subjected to glue coating treatment through a glue coating head. In reality, due to the mass production of circuit boards, the number of chip gold wires on the circuit boards that need to be subjected to glue coating treatment is large. In the above comparative document, the circuit board is placed in the fixing frame manually, and after the chip gold wire is coated with glue, it is taken down manually. The time for stopping glue coating in the middle is relatively long, so the efficiency of glue coating on the chip gold wire is reduced. Therefore, it is urgent for this field to improve the chip gold wire glue coating device to solve the defects of the prior art. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Please refer to Figures 1-5 , a chip gold wire glue application device, including a conveyor device 1 for conveying the circuit board 2. There is an inverted U-shaped moving frame 3 between the opposite sides of the conveyor device 1 in the conveying direction. The inner top wall of the moving frame 3 is provided with a moving seat 4 in the same direction as the conveying direction of the conveyor device 1. The lower side of the moving seat 4 is provided with a first telescopic device 5. The telescopic lower end of the first telescopic device 5 is fixedly installed with a glue application head 6. The upper side of the moving frame 3 is fixedly installed with a glue storage tank 7. There is a communicating and elastic delivery pipe 8 between the glue storage tank 7 and the glue application head 6. On both sides of the conveyor device 1, there is a first driving unit 9 for moving the moving frame 3 along the conveying direction of the conveyor device 1. On one side of the moving frame 3, there is a second driving unit 10 for moving the moving seat 4 along the upper part of the moving frame 3. On the moving seat 4, there is a third driving unit 11 for driving the first telescopic device 5 to move along the moving seat 4. On the opposite inner sides of the moving frame 3, there are positioning units 12 for positioning the circuit board 2. At the starting position of the conveyor device 1, there is a righting unit 13 for righting the circuit board 2. On one side of the moving frame 3, there is a main controller 14 for control. On the inner side wall of the moving frame 3, there is a first recognition device 15 for recognizing the circuit board 2.

[0030] Specifically, when it is necessary to apply glue to the chip gold wires on the circuit board 2, the circuit board 2 is placed at intervals on the conveyor belt of the conveying device 1 by manual or automatic loading robotic arm. The main controller 14 controls and coordinates the overall device. The above-mentioned conveying device 1 is a known prior art for conveying the circuit board 2. The circuit board 2 is intermittently conveyed by the conveying device 1. When the circuit board 2 moves to the position of the straightening unit 13, it is straightened by the straightening unit 13 to prevent the circuit board 2 from shifting on the conveying device 1. When the conveying device 1 moves the circuit board 2 to the position of the moving frame 3, the conveying device 1 stops conveying. The position of the chip gold wires on the circuit board 2 is identified by the first identification device 15. The first identification device 15 is a monitoring camera that is a known prior art and has an identification effect. The position of the circuit board 2 is positioned by the positioning unit 12. The lower end of the telescopic part of the first telescopic device 5 drives the glue applicator head 6 to move downward. The conveying pipe 8 conveys the glue in the glue storage tank 7 to the glue applicator head 6. The glue applicator head 6 applies glue to the chip gold wires on the circuit board 2, and the glue applicator head 6 is driven to move along the moving frame 3 by the second driving unit 10. The glue applicator head 6 is driven to move along the conveying direction of the conveying device 1 by the third driving unit 11. The two directions cooperate to move to apply glue to the chip gold wires on the circuit board 2. After the glue application to the chip gold wires on the circuit board 2 is completed, the conveying device 1 is started again to convey the circuit board 2 to a suitable position for storage. The glue application to the chip gold wires on the circuit board 2 is carried out by pipeline automation, thereby improving the efficiency of applying glue to the chip gold wires. When the position deviation between the circuit board 2 and the moving frame 3 is large, the first driving unit 9 is started. The first driving unit 9 drives the moving frame 3 to move along the conveying device 1, thereby adjusting the position of the moving frame 3 and improving the applicability of the overall device.

[0031] As a technical optimization scheme of the present invention, the first driving unit 9 includes first sliding blocks 16 fixedly connected to both ends of the moving frame 3. Bearing seats 17 are fixedly installed on both sides of the conveying device 1. A first sliding groove 18 adapted to the first sliding block 16 is formed on the upper side of the bearing seat 17. A first lead screw 19 is rotatably connected in the first sliding groove 18. The first lead screw 19 passes through the first sliding block 16 and is threadedly connected to the first sliding block 16. First driving motors 20 that are synchronous and have output ends fixedly connected to the corresponding first lead screws 19 are fixedly installed at the ends of the two bearing seats 17.

[0032] Specifically, two synchronous first driving motors 20 are started simultaneously. The output end of the first driving motor 20 drives the first lead screw 19 to rotate. The first lead screw 19 passes through the first sliding block 16 and is threadedly connected to the first sliding block 16. Therefore, when the first lead screw 19 rotates, it drives the first sliding block 16 to move within the first sliding groove 18. The two first sliding blocks 16 move simultaneously, thereby driving the moving frame 3 to move along the conveying direction of the conveying device 1, adjusting the position of the moving frame 3 to a position adapted to the circuit board 2, and improving the applicability of the overall device.

[0033] As a technical optimization scheme of the present invention, the second driving unit 10 includes a second sliding block 21 fixedly installed on the upper side of the moving seat 4. A second sliding groove 22 adapted to the second sliding block 21 is provided on the inner top wall of the moving frame 3. A second lead screw 23 is rotatably connected within the second sliding groove 22. The second lead screw 23 passes through the second sliding block 21 and is threadedly connected to the second sliding block 21. One side of the moving frame 3 is fixedly installed with a second driving motor 24 whose output end is fixedly connected to one end of the second lead screw 23.

[0034] Specifically, when the second driving motor 24 is started, the output end of the second driving motor 24 drives the second lead screw 23 to rotate. The second lead screw 23 passes through the second sliding block 21 and is threadedly connected to the second sliding block 21. Therefore, when the second lead screw 23 rotates, it drives the second sliding block 21 to move within the second sliding groove 22. The second sliding block 21 drives the moving seat 4 to move along the moving frame 3, and the moving seat 4 drives the glue application head 6 to move synchronously, achieving the effect of moving the glue application head 6 along the moving frame 3.

[0035] As a technical optimization scheme of the present invention, the third driving unit 11 includes a third sliding block 25 fixedly installed at the upper end of the first telescopic device 5. A third sliding groove 26 adapted to the third sliding block 25 is provided on the lower side of the moving seat 4. A third lead screw 27 is rotatably connected within the third sliding groove 26. The third lead screw 27 passes through the third sliding block 25 and is threadedly connected to the third sliding block 25. One end of the moving seat 4 is fixedly installed with a third driving motor 28 whose output end is fixedly connected to one end of the third lead screw 27.

[0036] Specifically, when the third driving motor 28 is started, the output end of the third driving motor 28 drives the third lead screw 27 to rotate. The third lead screw 27 passes through the third sliding block 25 and is threadedly connected to the third sliding block 25. When the third sliding block 25 moves, it drives the first telescopic device 5 to move along the length direction of the moving seat 4, achieving the movement of the glue application head 6 along the conveying direction of the conveying device 1.

[0037] As a technical optimization solution of the utility model, the positioning unit 12 includes fixed seats 29 respectively and fixedly installed on the opposite side walls inside the moving frame 3. Both of the opposite sides of the two fixed seats 29 are provided with two symmetric second telescopic devices 30. The two second telescopic devices 30 on each fixed seat 29 are in a V-shaped configuration. The telescopic end of each second telescopic device 30 is fixedly installed with a Y-shaped connecting frame 31. The lower side of the end of each connecting frame 31 away from the second telescopic device 30 is rotatably connected with a pressing roller 32. One end of each second telescopic device 30 close to the fixed seat 29 is fixedly connected with a fourth sliding block 33. A fourth sliding groove 34 adapted to the fourth sliding block 33 is opened on one side of the fixed seat 29. A first bidirectional lead screw 35 is rotatably connected in the fourth sliding groove 34. A fourth driving motor 36 with one end fixedly connected to one end of the first bidirectional lead screw 35 is fixedly installed at one end of the fixed seat 29. When the first bidirectional lead screw 35 rotates, it drives the two fourth sliding blocks 33 to move towards or away from each other.

[0038] Specifically, when the position of the moving frame 3 is adapted to the circuit board 2 on the conveying device 1, the second telescopic device 30 is started. Since the front straightening unit 13 has straightened the circuit board 2, the circuit board 2 is basically located in the middle of the conveying device 1. The telescopic end of the second telescopic device 30 drives the connecting frame 31 to approach the edge of the circuit board 2. The pressing roller 32 rotatably connected to the side of the connecting frame 31 pushes the circuit board 2, so that the circuit board 2 is located in the middle of the moving frame 3. The pressing roller 32 has elasticity, and multiple pressing rollers 32 limit and fix the circuit board 2, improving the stability when the glue applicator head 6 applies glue to the chip gold wires on the circuit board 2. When applying glue to the chip gold wires on circuit boards 2 of different sizes, the fourth driving motor 36 can be started. The output end of the fourth driving motor 36 drives the first bidirectional lead screw 35 to rotate. The threads on the side of the first bidirectional lead screw 35 are symmetrically arranged in the reverse direction. When the first bidirectional lead screw 35 rotates, it drives the two fourth sliding blocks 33 to move towards or away from each other in the fourth sliding groove 34. The two fourth sliding blocks 33 drive the two second telescopic devices 30 to move towards or away from each other, achieving the effect of positioning circuit boards 2 of different sizes and improving the applicability of the overall device.

[0039] As a technical optimization solution of the present utility model, the straightening unit 13 includes two fixing plates 37 symmetrically and fixedly installed on the upper part of the conveying device 1. There are two straightening plates 38 between the two fixing plates 37. A second bidirectional lead screw 39 passing through the straightening plate 38 and threadedly connected to the straightening plate 38 is rotatably connected between the two fixing plates 37. A fifth driving motor 40 with an output end fixedly connected to one end of the second bidirectional lead screw 39 is fixedly installed on one side of one fixing plate 37. A guiding column 41 passing through the straightening plate 38 is fixedly connected between the two fixing plates 37. An installation plate 42 fixedly installed with the conveying device 1 is provided on one side of the fixing plate 37. A second identification device 43 for identifying the circuit board 2 is fixedly installed on one side of the installation plate 42.

[0040] Specifically, when the circuit board 2 is placed on the conveying device 1 for conveying, the second identification device 43 can identify the circuit board 2 on the conveying device 1. After it is identified that the circuit board 2 is located between the two straightening plates 38, the conveying device 1 stops conveying. At this time, the glue application head 6 applies glue to the chip gold wires on the circuit board 2 located below the moving frame 3. At the same time, the fifth driving motor 40 is started. The output end of the fifth driving motor 40 drives the second bidirectional lead screw 39 to rotate. The thread teeth on the side of the second bidirectional lead screw 39 are oppositely and symmetrically arranged. When the second bidirectional lead screw 39 rotates, it drives the two straightening plates 38 to move towards each other to straighten the circuit board 2 located on the conveying device 1, facilitating the positioning unit 12 to position the circuit board 2 later. When the straightening plate 38 moves, it moves on the side of the guiding column 41, and the guiding column 41 limits and guides the straightening plate 38.
