Description

Technical Field

[0001] This utility model relates to the field of electronic component dispensing technology, and in particular to a dispensing machine for electronic components. Background Technology

[0002] In the field of electronic component manufacturing, the dispensing process is a crucial step in achieving component bonding, sealing, and insulation, and the performance of the equipment directly affects product quality and production efficiency. With the rapid development of technologies such as semiconductors, 5G communications, and the Internet of Things, electronic components are showing a trend towards miniaturization, high precision, and diversification, which places higher demands on the mechanical precision, compatibility, and ease of operation of dispensing machines.

[0003] In existing dispensing machines, the mechanical structure design typically employs a fixed or bolt-fastened dispensing head installation method. This type of structure primarily uses rigid connecting components such as mechanical bolts and clips to fix the dispensing head to the dispensing actuator. Its technical principle is based on the stability design of traditional mechanical connections, and the installation and removal of the dispensing head are completed manually using tools. When facing dispensing needs of different specifications, operators must rely on specialized tools such as screwdrivers to loosen or tighten bolts one by one, or use complex clip-on structures to replace the dispensing head. The entire process depends on the precision and skill of manual operation.

[0004] However, existing dispensing head replacement methods have significant drawbacks. When different sizes of dispensing heads need to be replaced to adapt to diverse dispensing processes, operators must manually disassemble screws or use special tools to handle complex snap-fit ​​structures. This process is time-consuming per operation, especially in scenarios involving multi-variety, small-batch production. Frequent dispensing head replacements lead to a significant increase in production line downtime, severely impacting production efficiency. For example, in the small-batch customized production of electronic components, each dispensing head replacement requires time, resulting in reduced equipment utilization and failing to meet the production demands of rapid model changes. Therefore, a dispensing machine for electronic components is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dispensing machine for electronic components, which aims to improve the problem that in the prior art, changing different specifications of glue heads requires manual disassembly of screws or special tools, which takes a long time for a single operation and increases the downtime of the production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dispensing machine for electronic components includes a base, a protective shell on the top of the base, a rotating door on the inner wall of the protective shell, a glue carrier box fixedly connected to the top of the protective shell, a multi-angle moving mechanism on the inner wall of the protective shell, a dispensing tube on the inner wall of the multi-angle moving mechanism, one end of the glue carrier box fixedly connected to the top of the dispensing tube, and a replacement component on the outer wall of the dispensing tube.

[0008] The replacement component includes a first clamping plate, the outer wall of which is fixedly connected to the outer wall of the dispensing tube. A second clamping plate is fixedly connected to the outer wall of the dispensing tube. A dispensing head is provided at the bottom of the dispensing tube. The outer wall of the dispensing head is fixedly connected to the first clamping plate. The outer wall of the dispensing head is fixedly connected to the second clamping plate. The side wall of the second clamping plate is provided on the outer wall of the second clamping plate. The side wall of the first clamping plate is provided on the side wall of the first clamping plate.

[0009] As a further description of the above technical solution:

[0010] A first support plate is fixedly connected to the inner wall of the base, and a second support plate is fixedly connected to the top of the base.

[0011] As a further description of the above technical solution:

[0012] A hydraulic cylinder is fixedly connected to the bottom of the second support plate, and a connecting plate is fixedly connected to the output end of the hydraulic cylinder.

[0013] As a further description of the above technical solution:

[0014] A sliding block is fixedly connected to one end of the connecting plate, and a slide rail is slidably connected inside the sliding block.

[0015] As a further description of the above technical solution:

[0016] The bottom of the slide rail is fixedly connected to the top of the second support plate, and the top of the sliding block is fixedly connected to a connecting block.

[0017] As a further description of the above technical solution:

[0018] A hollow block is fixedly connected to the top of the connecting block, and a collar is fixedly connected inside the hollow block.

[0019] As a further description of the above technical solution:

[0020] A sliding post is slidably connected to the inner wall of the collar, and a spring is sleeved on the side wall of the sliding post. One end of the spring is fixedly connected to the outer wall of the sliding post, and the other end of the spring is fixedly connected to the side wall of the collar. A third clamping plate is fixedly connected to one end of the sliding post, and the bottom of the third clamping plate is slidably connected to the top of the first support plate. A gear is rotatably connected to the bottom of the first support plate.

[0021] As a further description of the above technical solution:

[0022] A rack is fixedly connected to the bottom of the sliding block, and the rack meshes with the gear.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the first clamping plate on the outer wall is rotated by rotating the glue head, which then causes the side wall of the first clamping plate to detach from the side wall of the first clamping plate, and the side wall of the second clamping plate to detach from the side wall of the second clamping plate. This achieves the effect of quickly disassembling the glue head, solves the problem that it is necessary to manually remove screws or special tools when changing glue heads of different specifications, which takes a long time for each operation and increases the downtime of the production line. This improves the convenience of the dispensing machine for electronic components.

[0025] 2. In this utility model, a hydraulic cylinder drives a sliding block to move. The sliding block then moves a rack to rotate on the outer wall of a meshing gear. Subsequently, through the reverse meshing principle of the rack, another sliding block is moved. At the same time, the side wall of the third clamping plate is pressed against the side wall of the component, and the sliding column of the side wall is moved. The spring on the outer wall is also moved to retract, achieving the effect of adaptive clamping of electronic components. This solves the problem that fixed fixtures cannot adapt to workpieces of different sizes / shapes, and that after clamping, displacement is easily caused by gaps, resulting in dispensing position deviation exceeding ±0.1mm, which causes BGA package solder ball bridging or cold solder joints. This improves the stability of the dispensing machine for electronic components. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-4 An embodiment of this utility model provides: a dispensing machine for electronic components, including a base 1, a protective shell 2 on the top of the base 1, a rotating door 3 on the inner wall of the protective shell 2, a glue tank 4 fixedly connected to the top of the protective shell 2, a multi-angle moving mechanism 5 on the inner wall of the protective shell 2, a dispensing tube 7 on the inner wall of the multi-angle moving mechanism 5, one end of the glue tank 4 fixedly connected to the top of the dispensing tube 7, and a replacement component on the outer wall of the dispensing tube 7;

[0037] The replacement component includes a first clamping plate 8, the outer wall of which is fixedly connected to the outer wall of the dispensing tube 7. A second clamping plate 12 is fixedly connected to the outer wall of the dispensing tube 7. A dispensing head 10 is provided at the bottom of the dispensing tube 7. By rotating the dispensing head 10, the first clamping plate 9 is disengaged from the first clamping plate 8, and the second clamping plate 11 is disengaged from the second clamping plate 12, so as to realize the quick replacement of the dispensing head 10 and solve the problem of time-consuming disassembly of traditional threaded connections. The outer wall of the dispensing head 10 is fixedly connected to the first clamping plate 9, and the outer wall of the dispensing head 10 is fixedly connected to the second clamping plate 11. The side wall of the second clamping plate 12 is set on the outer wall of the second clamping plate 11, and the side wall of the first clamping plate 9 is set on the side wall of the first clamping plate 8.

[0038] Reference Figures 5-7A first support plate 6 is fixedly connected to the inner wall of the base 1, and a second support plate 14 is fixedly connected to the top of the base 1. A hydraulic cylinder 15 is fixedly connected to the bottom of the second support plate 14. The hydraulic cylinder is an Airtac ACQ series thin-type hydraulic cylinder with a cylinder diameter of 32mm and a stroke of 50mm, used to provide linear driving force. This is existing technology and will not be described in detail here. The hydraulic cylinder 15 works with the sliding block 17 and the slide rail 18 for linear drive. Through the bidirectional meshing transmission of the gear 19 and the rack 20, the third clamping plates 13 on both sides move synchronously and symmetrically, ensuring that the clamping force is evenly distributed. The hydraulic cylinder 15 drive system consists of a cylinder body, piston, and sealing ring, used to output linear thrust. It is a standard power module for industrial equipment and is existing technology, which will not be described in detail here. A connecting plate 16 is fixedly connected to the output end of the hydraulic cylinder 15. A sliding block 17 is fixedly connected to one end of the connecting plate 16. A slide rail 18 is slidably connected inside the sliding block 17. The bottom of the slide rail 18 is fixedly connected to the top of the second support plate 14, and a connecting block 2 is fixedly connected to the top of the sliding block 17. 1. A hollow block 22 is fixedly connected to the top of the connecting block 21. A collar 23 is fixedly connected inside the hollow block 22. A sliding column 24 is slidably connected to the inner wall of the collar 23. A spring 25 is sleeved on the side wall of the sliding column 24. The spring 25 is made of elastic material. Its function is to make the third clamping plate 13 fit tightly against the side wall of the electronic component through its own rebound force when the third clamping plate 13 clamps the electronic component, which increases the uniformity and stability of the clamping force, prevents the electronic component from shifting during the dispensing process, improves the accuracy of dispensing, and also has a certain buffering effect to avoid damage to the electronic component due to excessive clamping force. One end of the spring 25 is fixedly connected to the outer wall of the sliding column 24, and the other end of the spring 25 is fixedly connected to the side wall of the collar 23. The third clamping plate 13 is fixedly connected to one end of the sliding column 24. The bottom of the third clamping plate 13 is slidably connected to the top of the first support plate 6. A gear 19 is rotatably connected to the bottom of the first support plate 6. A rack 20 is fixedly connected to the bottom of the sliding block 17. The rack 20 meshes with the gear 19.

[0039] Working principle: When using the dispensing machine for electronic components and clamping the electronic components, the output end of the hydraulic cylinder 15 first drives the connecting plate 16 to move. Then, during the movement of the connecting plate 16, the top sliding block 17 is moved, and the sliding block 17 slides against the side wall of the slide rail 18. Then, during the movement of the sliding block 17, the rack 20 is moved, and it moves against the outer wall of the gear 19 it meshes with. Through the bidirectional meshing effect, another sliding block 17 is moved along with it. Next, during the movement of the sliding block 17, the third clamping plate 13 is moved to be close to the side wall of the electronic component. Then, during the movement of the third clamping plate 13, the sliding column 24 on the side wall is moved to slide against the inner wall of the collar 23. During the movement of the sliding column 24, the spring 25 on the outer wall is contracted, and the rebound force of the spring 25 drives the third clamping plate 13 to be pressed tightly against the side wall of the electronic component, achieving the effect of adaptive clamping of the electronic component.

[0040] When replacing the rubber head 10, first rotate the rubber head 10. The force on the rubber head 10 will cause the first clamping plate 9 on the outer wall to rotate. Then, during the process of the first clamping plate 9 being subjected to force, it will rotate on the side wall of the first clamping plate 8 and cause the side wall of the first clamping plate 9 to disengage from the side wall of the first clamping plate 8. Subsequently, during the rotation of the rubber head 10, the second clamping plate 11 on the outer wall will disengage from the inner wall of the second clamping plate 12, thereby achieving the effect of quickly removing the rubber head 10.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
