Description

Technical Field

[0001] This utility model relates to the field of transistor processing technology, specifically to a transistor processing sealing and soldering machine. Background Technology

[0002] In transistor manufacturing, sealing and bonding machines (also known as soldering machines or packaging equipment) are essential tools, primarily used for the encapsulation and connection of electronic components. In transistor manufacturing, sealing and bonding machines are used to encapsulate semiconductor chips within a housing, ensuring their physical protection and providing electrical connectivity.

[0003] When using existing sealing and welding machines to fix and seal transistor casings, it is usually necessary to seal and weld each of the four sides separately. This sealing and welding process affects the sealing and welding efficiency to some extent. Furthermore, if the material being sealed and welded is displaced during the sealing and welding process, it can easily affect the sealing and welding effect. Therefore, we propose a sealing and welding machine for transistor processing. Utility Model Content

[0004] The purpose of this invention is to provide a sealing and soldering machine for transistor processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transistor sealing and soldering machine, comprising a work plate and two sets of sealing and soldering heads for sealing and soldering transistors. A support base is fixedly installed at the bottom of the work plate, and a support mechanism for supporting and rotating the transistor is provided at the top of the work plate. The support mechanism drives the transistor to move downwards towards the sealing and soldering heads. A positioning mechanism for positioning the top of the transistor to be sealed and soldered is provided on the support mechanism. A drive mechanism for driving the sealing and soldering heads to move along the "X" axis and the "Z" axis is provided at the top of the work plate.

[0006] Furthermore, the bearing mechanism includes a first electric slide rail, a first electric slider, a first support column, a movable seat, and a support frame. Two sets of first electric slide rails are fixedly installed on the top of the working plate. A first electric slider is slidably connected to the first electric slide rail. A movable seat is fixedly connected to the top of the first electric slider through the first support column. A support frame is fixedly installed on the top of the movable seat. A rotary table is rotatably connected to the support frame. A bearing mold is fixedly installed on the top of the rotary table. A first drive motor is fixedly installed at the bottom of the movable seat. The output end of the first drive motor is fixedly connected to the rotary table.

[0007] Furthermore, the positioning mechanism includes a first support frame, a limiting sleeve, a limiting rod, a connecting plate, a spring, a second support column, and a ball bearing. The first support frame is fixedly installed on one side of the support frame, and the limiting sleeve is fixedly installed at the bottom of the first support frame. The limiting rod is slidably connected inside the limiting sleeve. The connecting plate is fixedly installed on the top of the limiting rod, and the second support column is fixedly installed at the bottom of the connecting plate. The ball bearing is rotatably connected to the bottom of the second support column. A spring is fixedly connected to the top of the first support frame and outside the limiting rod, and the top of the spring is fixedly connected to the connecting plate.

[0008] Furthermore, the positioning mechanism also includes a limiting ring and a positioning rod. A limiting ring is fixedly connected to one side of the first support frame, and a positioning rod is slidably connected inside the limiting ring. The top of the positioning rod is fixedly connected to the limiting rod.

[0009] Furthermore, the driving mechanism includes a second support frame, a second electric slide rail, a drive frame, a sliding sleeve, a dual-axis screw, and a mounting frame. The second support frame is fixedly installed on the top of the working plate. The second electric slide rail is fixedly installed on one side of the second support frame.

A threaded sleeve is threadedly connected to the outside of the dual-axis screw. A second connecting plate is fixedly connected to the outside of the sliding sleeve and the threaded sleeve. A sealing head is fixedly connected to one side of the second connecting plate via a mounting frame.

[0010] Furthermore, the positioning rod has a rectangular cross-section, and each of the four corners of the positioning rod has an arc-shaped chamfer.

[0011] Compared with the prior art, the present invention has the following advantages: The supporting mechanism of the present invention can support the transistor to be sealed and move the transistor downwards towards the two sets of sealing heads. In this way, the driving mechanism can drive the sealing heads to move along the "X" and "Z" axes, so that the two sets of sealing heads can be used to seal the two sides above the transistor. After the sealing of the two sides is completed, the supporting mechanism can drive the transistor to rotate, thereby sealing the other two sides above the transistor. This double-sided sealing process improves the sealing efficiency to a certain extent compared with single-sided sealing. Moreover, the positioning mechanism can always be in contact with the top of the transistor to prevent positional displacement during the sealing process and ensure the sealing accuracy.

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a transistor sealing and soldering machine, including a work plate 1 and two sets of sealing and soldering heads 6 for sealing and soldering transistors. A support base 2 is fixedly installed at the bottom of the work plate 1, and a support mechanism 3 for supporting and rotating transistors is provided at the top of the work plate 1. The support mechanism 3 drives the transistors to move downwards towards the sealing and soldering heads 6. A positioning mechanism 4 is provided on the support mechanism 3 for positioning the top of the transistors to be sealed and soldered. A driving mechanism 5 is provided at the top of the work plate 1 for driving the sealing and soldering heads 6 to move along the "X" axis and the "Z" axis.

[0019] The supporting mechanism 3 can support the transistor to be sealed and move it downwards towards the two sets of sealing heads 6. The driving mechanism 5 can then move the sealing heads 6 along the "X" and "Z" axes, allowing the two sets of sealing heads 6 to seal the two sides above the transistor. After sealing the two sides, the supporting mechanism 3 can rotate the transistor to seal the other two sides above it. This double-sided sealing process improves sealing efficiency to some extent compared to single-sided sealing. Moreover, the positioning mechanism 4 can always be in contact with the top of the transistor to prevent positional shift during the sealing process and ensure sealing accuracy.

[0020] Please see Figure 1 and Figure 3 The bearing mechanism 3 includes a first electric slide rail 7, a first electric slider 8, a first support column 9, a movable seat 10, and a support frame 11. Two sets of first electric slide rails 7 are fixedly installed on the top of the working plate 1. The first electric slider 8 is slidably connected to the first electric slide rail 7. The movable seat 10 is fixedly connected to the top of the first electric slider 8 through the first support column 9. The support frame 11 is fixedly installed on the top of the movable seat 10. A rotary table 12 is rotatably connected to the support frame 11. A bearing mold 13 is fixedly installed on the top of the rotary table 12. A first drive motor 14 is fixedly installed on the bottom of the movable seat 10. The output end of the first drive motor 14 is fixedly connected to the rotary table 12.

[0021] The supporting mold 13 can support the material to be sealed and welded. Then, the positioning mechanism 4 positions the material. The first electric slider 8 can move along the first electric slide rail 7 to the bottom of the sealing head 6. Then, the two sets of sealing heads 6 can be used to seal and weld the two sides of the material. After the sealing and welding of two sides is completed, the first drive motor 14 can drive the rotary table 12 and the supporting mold 13 to rotate, so that the other two sides of the material can be sealed and welded.

[0022] Please see Figure 1 and Figure 3The positioning mechanism 4 includes a first support frame 15, a limiting sleeve 16, a limiting rod 17, a connecting plate 18, a spring 19, a second support column 20, and a ball bearing 21. The first support frame 15 is fixedly installed on one side of the support frame 11. The limiting sleeve 16 is fixedly installed at the bottom of the first support frame 15. The limiting rod 17 is slidably connected inside the limiting sleeve 16. The connecting plate 18 is fixedly installed at the top of the limiting rod 17. The second support column 20 is fixedly installed at the bottom of the connecting plate 18. The ball bearing 21 is rotatably connected to the bottom of the second support column 20. The spring 19 is fixedly connected to the top of the first support frame 15 and outside the limiting rod 17. The top of the spring 19 is fixedly connected to the connecting plate 18. The positioning mechanism 4 also includes a limiting ring 22 and a positioning rod 23. The limiting ring 22 is fixedly connected to one side of the first support frame 15. The positioning rod 23 is slidably connected inside the limiting ring 22. The top of the positioning rod 23 is fixedly connected to the limiting rod 17.

[0023] When materials need to be placed inside the bearing mold 13, the connecting plate 18 is pulled upwards to disengage the positioning rod 23 from the limiting ring 22. Then, the connecting plate 18 is rotated 90° to move the second support column 20 and the ball bearing 21 away from the top of the bearing mold 13, making it easier to place materials inside the bearing mold 13. After placement, the connecting plate 18 is lifted and rotated 90° counterclockwise. Then, the tension of the spring 19 is used to pull the connecting plate 18, the second support column 20, and the ball bearing 21 downwards, ensuring that the ball bearing 21 is always in contact with and pressed against the top of the material. The rotating ball bearing 21 can also keep the material pressed even when the bearing mold 13 and the material are rotated and adjusted.

[0024] Please see Figure 1 , Figure 2 and Figure 4 The driving mechanism 5 includes a second support frame 24, a second electric slide rail 25, a drive frame 27, a sliding sleeve 29, a dual-axis screw 30, and a mounting frame 34. The second support frame 24 is fixedly installed on the top of the working plate 1. The second electric slide rail 25 is fixedly installed on one side of the second support frame 24. The drive frame 27 is slidably connected to the second electric slide rail 25 via a second electric slider 26. A limit slide rod 28 is fixedly installed on the drive frame 27. The dual-axis screw 30 is rotatably connected to the drive frame 27. A second drive motor 32 is fixedly connected to one side of the drive frame 27. The output end of the second drive motor 32 is fixedly connected to the dual-axis screw 30. The sliding sleeve 29 is slidably connected to the outside of the limit slide rod 28. A threaded sleeve 31 is threadedly connected to the outside of the dual-axis screw 30. A second connecting plate 33 is fixedly connected to the outside of the sliding sleeve 29 and the threaded sleeve 31. A sealing head 6 is fixedly connected to one side of the second connecting plate 33 via the mounting frame 34.

[0025] When the sealing head 6 needs to move along the Z-axis, the second electric motor 25 and the second electric slider 26 can drive the drive frame 27 to move up and down. When the sealing head 6 needs to be adjusted along the X-axis, the second drive motor 33 drives the dual-axis screw 30 to rotate. The rotating dual-axis screw 30 can then drive the threaded sleeve 31, the second connecting plate 33, and the mounting frame 34 to move, thereby completing the X-axis position adjustment of the sealing head 6. When the position of the second connecting plate 33 is adjusted, it can be limited by the limiting slide rod 28 and the sliding sleeve 29 to ensure the stability of the movement of the mounting frame 34 and the sealing head 6.

[0026] Please see Figure 1 and Figure 3 The positioning rod 23 has a rectangular cross-section and is provided with arc-shaped chamfers at all four corners. The rectangular cross-section of the positioning rod 23 can prevent it from shifting again after the angle adjustment is completed, while the arc-shaped chamfers can facilitate the insertion of the positioning rod 23 into the interior of the limiting ring 22.

[0027] In use, firstly, the supporting mold 13 can support the material to be sealed and welded. Then, the positioning mechanism 4 positions the material. Next, the first electric slider 8 moves along the first electric slide rail 7 towards the sealing head 6. Then, the two sealing heads 6 can be used to seal and weld both sides of the material. After two sides are sealed, the first drive motor 14 drives the rotary table 12 and the supporting mold 13 to rotate, thus sealing and welding the other two sides of the material. When the material needs to be placed inside the supporting mold 13, the connecting plate 18 is pulled upwards, causing the positioning rod 23 to disengage from the limiting ring 22. Then, the connecting plate 18 is rotated 90°, moving the second support column 20 and the ball bearing 21 away from the top of the supporting mold 13, making it easier to place the material inside. After placement, the connecting plate 18 is pulled up, rotating it 90° counterclockwise, and then... The tension of spring 19 pulls the connecting plate 18, the second support column 20, and the ball bearing 21 downwards, ensuring that the ball bearing 21 remains in contact with and presses against the top of the material. The rotating ball bearing 21 also maintains material pressure even when the mold 13 and the material's rotational position are adjusted. When the sealing head 6 needs to move along the Z-axis, the second electric motor 25 and the second electric slider 26 move the drive frame 27 up and down. When the sealing head 6 needs to be adjusted along the X-axis, the second drive motor 33 rotates the dual-axis screw 30. The rotating screw 30 then moves the threaded sleeve 31, the second connecting plate 33, and the mounting frame 34, thus completing the X-axis position adjustment of the sealing head 6. The second connecting plate 33 can be positioned using the limiting slide rod 28 and the sliding sleeve 29 to ensure the stability of the mounting frame 34 and the sealing head 6.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
