Description

Technical Field

[0001] This utility model relates to the field of wire bonding machine packaging platform technology, specifically to a general-purpose wire bonding machine packaging platform. Background Technology

[0002] Wire bonding machines generally refer to ultrasonic wire bonding machines, which are a special method of connecting the same or different metals by using the mechanical vibration energy of ultrasonic frequencies. The wire bonding machine packaging platform is a precision platform inside the wire bonding machine. Its core function is to accurately fix and position the chip or other semiconductor device to be welded, ensuring that the wire bonding process can be carried out with high precision and high efficiency.

[0003] With the rapid development of the semiconductor market, packaging forms are becoming increasingly diversified. Traditional wire bonding machine packaging platforms are mostly designed for specific purposes, that is, optimized for a single product of a specific size and shape. These dedicated platforms have extremely poor flexibility. When it is necessary to switch to products with different packaging types or sizes, operators must disassemble the entire dedicated platform and replace it with another set of dedicated platforms that match it. This is not only time-consuming and labor-intensive, leading to reduced equipment utilization and increased production cycle and labor costs, but also the frequent disassembly and assembly can easily introduce mechanical errors, affecting the long-term positioning accuracy of the equipment.

[0004] To meet the demand for multi-variety, small-batch production, carrier stages with certain adjustment functions have emerged on the market. However, most existing technologies have obvious limitations: they rely on cumbersome manual adjustment and locking structures, lack efficient and uniform temperature control systems, and cannot meet the different requirements of different packaging materials for welding temperature. Based on this, a general-purpose wire bonding machine packaging carrier stage is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a universal wire bonding machine packaging platform to solve the problems of relying on cumbersome manual adjustment and locking structures, lacking an efficient and uniform temperature control system, and being unable to meet the different requirements of different packaging materials for welding temperature.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A general-purpose wire bonding machine packaging platform includes a support platform, an X-axis moving platform, a Y-axis moving platform and a base. The Y-axis moving platform is disposed on the upper side of the X-axis moving platform and the base is disposed on the upper side of the Y-axis moving platform. Guide plates are fixed on both the front and rear sides of the upper surface of the support platform, and positioning mechanisms for accommodating products of different sizes are provided on both the front and rear sides of the upper surface of the base. The positioning mechanism includes a U-shaped plate on the upper surface of the base. A threaded rod with one end extending through and to the lower side is threadedly connected to the center of the upper surface of the U-shaped plate. A pressure plate is rotatably connected to the lower surface of the threaded rod via a bearing. Adjustment components are provided on both the left and right sides of the U-shaped plate.

[0007] The above technical solution allows for the adjustment of the pressure plate height and clamping force on the product by rotating the screws on the two U-shaped plates, thus adapting to products of different thicknesses. Loosening and tightening the limit pins adjusts the position of the U-shaped plates on the base to accommodate the length and width of different products, thereby improving the versatility of the wire bonding machine packaging platform.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, limiting protrusions are provided on both the front and rear sides of the lower surface of the base, and limiting grooves are provided on both the front and rear sides of the top of the guide plate for sliding of the limiting protrusions.

[0010] Through the above technical solution, the limiting protrusion and limiting groove can guide the movement of the base during the movement of the base, so that it moves smoothly.

[0011] Furthermore, the adjusting component includes a fixing plate fixed to both sides of the U-shaped plate, and a limiting pin with one end passing through and extending to its lower side is slidably connected to the upper surface of the fixing plate. The upper surface of the base is provided with two rows of symmetrically arranged limiting grooves, and the outer diameter of the limiting pin is adapted to the inner diameter of the limiting groove.

[0012] Through the above technical solution, the position of the pressure plate is quickly locked and separated by the insertion and removal of the limiting pin and the preset limiting groove, and can be adjusted to the appropriate position according to different sized products.

[0013] Furthermore, the X-axis moving platform includes a first sliding seat fixed on the support platform, a first motor fixed on the left side of the first sliding seat, a first screw rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the first sliding seat via bearings, the output shaft of the first motor passes through and extends into the inner cavity of the first sliding seat and is fixed to the first screw, a first movable block is threadedly connected to the outer surface of the first screw, and a first guide seat is fixed on the first movable block.

[0014] The above technical solution converts rotary motion into linear motion by driving a screw with a motor, which enables adjustment of the base's position on the support platform in the left and right directions.

[0015] Furthermore, the Y-axis moving platform includes a second sliding seat fixed on a first guide seat. A second motor is fixed to the rear side of the second sliding seat. A second screw is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the second sliding seat via a bearing. The output shaft of the second motor passes through and extends into the inner cavity of the second sliding seat and is fixed to the second screw. A second movable block is threadedly connected to the outer surface of the second screw. A second guide seat is fixed on the second movable block.

[0016] The above technical solution converts rotary motion into linear motion by driving the second screw with the second motor, which enables the adjustment of the position of the base in the front-to-back direction on the support platform.

[0017] Furthermore, the top of the front and rear sides of the first sliding seat and the top of the left and right sides of the second sliding seat are provided with sliding holes for the first guide seat and the second guide seat to move horizontally. The cross-sectional shape of the first guide seat and the second guide seat is a U-shape. The upper surface of the first guide seat is fixed to the second sliding seat, and the upper surface of the second guide seat is fixed to the base.

[0018] Through the above technical solution, the cooperation between the sliding hole and the first and second guide seats can not only limit the movement of the first and second movable blocks, making them only able to move in a straight line, but also enhance the connection strength between them and the first and second sliding seats.

[0019] Furthermore, temperature sensors are embedded in the center and both ends of the upper surface of the base, multiple plate-shaped ceramic heaters are embedded in the top of the inner cavity of the base, and an S-shaped cooling channel is opened at the bottom of the inner cavity of the base.

[0020] The temperature sensors installed using the above technical solution can accurately determine the temperature uniformity of the entire heating area based on the real-time temperature data from these three points. When a batch of production is completed or when it is necessary to replace a temperature-sensitive product, the introduction of coolant can quickly remove the heat from the base, achieving rapid cooling. The S-shaped flow channel increases the contact area and contact time between the coolant and the base, thereby significantly improving the heat exchange efficiency.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: By rotating the screws on the two U-shaped plates, the height of the pressure plate and the clamping force on the product can be adjusted to accommodate products of different thicknesses. Loosening and tightening the limit pins can adjust the position of the U-shaped plates on the base to accommodate the length and width of different products, thus improving the versatility of the wire bonding machine's packaging platform. The temperature sensor can monitor real-time temperature data at three points to accurately determine the temperature uniformity of the entire heating area. When a batch of production is completed or when it is necessary to replace temperature-sensitive products, the introduction of coolant can quickly remove the heat from the base, achieving rapid cooling.

[0024] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] Example: Reference Figure 1 A general-purpose wire bonding machine packaging platform includes a support platform 1, an X-axis moving platform 2, a Y-axis moving platform 3, and a base 4. The Y-axis moving platform 3 is located on the upper side of the X-axis moving platform 2, and the base 4 is located on the upper side of the Y-axis moving platform 3. Guide plates 5 are fixed on both the front and rear sides of the upper surface of the support platform 1, and positioning mechanisms 6 for accommodating products of different sizes are provided on both the front and rear sides of the upper surface of the base 4.

[0027] refer to Figure 2 and Figure 3 The X-axis moving platform 2 includes a first sliding seat 21 fixed on the support platform 1. A first motor 22 is fixed on the left side of the first sliding seat 21. A first screw 23 is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the first sliding seat 21 via a bearing. The output shaft of the first motor 22 passes through and extends into the inner cavity of the first sliding seat 21 and is fixed to the first screw 23. A first movable block 24 is threadedly connected to the outer surface of the first screw 23. A first guide seat 25 is fixed on the first movable block 24.

[0028] In use, the output shaft of motor 22 starts to rotate, and the output shaft of motor 22 drives screw 23 to rotate synchronously. Movable block 24, which is threaded to screw 23, converts the rotational motion into its own linear motion. When movable block 24 moves, it drives guide seat 25 to move together, which can change the position of base 4 in the X-axis direction. The sliding hole on the top of sliding seat 21 provides guidance for the movement of guide seat 25, ensuring that its movement trajectory is a straight line.

[0029] The Y-axis moving platform 3 includes a second sliding seat 31 fixed on a first guide seat 25. A second motor 32 is fixed to the rear side of the second sliding seat 31. A second screw 33 is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the second sliding seat 31 via a bearing. The output shaft of the second motor 32 passes through and extends into the inner cavity of the second sliding seat 31 and is fixed to the second screw 33. A second movable block 34 is threadedly connected to the outer surface of the second screw 33. A second guide seat 35 is fixed on the second movable block 34.

[0030] In use, the control system sends a command to the second motor 32, causing its output shaft to rotate synchronously with the second screw 33, which in turn causes the second movable block 34 to move linearly. The second movable block 34 drives the second guide seat 35 and the base 4 to move. At this time, the second guide seat 35 slides in the sliding hole at the top of the second sliding seat 31, providing precise linear guidance for the second guide seat 35, thereby causing the position of the base 4 to change in the Y-axis direction.

[0031] In this embodiment, the top of the front and rear sides of the first sliding seat 21 and the top of the left and right sides of the second sliding seat 31 are provided with sliding holes for the first guide seat 25 and the second guide seat 35 to move horizontally. The cross-sectional shape of the first guide seat 25 and the second guide seat 35 is U-shaped. The upper surface of the first guide seat 25 is fixed to the second sliding seat 31, and the upper surface of the second guide seat 35 is fixed to the base 4.

[0032] refer to Figure 2 Limiting grooves 51 are provided on both the front and rear sides of the lower surface of the base 4, and limiting grooves 52 for sliding of the limiting grooves 51 are provided on both the front and rear sides of the top of the guide plate 5.

[0033] refer to Figure 4 The positioning mechanism 6 includes a U-shaped plate 61 disposed on the upper surface of the base 4. A threaded rod 62 with one end passing through and extending to the lower side is threadedly connected to the center of the upper surface of the U-shaped plate 61. A pressure plate 63 is rotatably connected to the lower surface of the threaded rod 62 through a bearing. Adjusting components are provided on both the left and right sides of the U-shaped plate 61.

[0034] refer to Figure 4 and Figure 5 The adjusting component includes a fixing plate 64 fixed on both sides of the U-shaped plate 61. A limiting pin 65 with one end passing through and extending to its lower side is slidably connected to the upper surface of the fixing plate 64. Two rows of symmetrically arranged limiting grooves 66 are opened on the upper surface of the base 4. The outer diameter of the limiting pin 65 is adapted to the inner diameter of the limiting groove 66, which realizes the quick locking and separation of the pressure plate 63 on the base 4, thereby adapting to the use of products of different sizes and improving the versatility of the equipment.

[0035] In use, move the two U-shaped plates 61 to the product position, place the product to be welded on the upper surface of the base 4, and then insert the two limiting pins 65 on the U-shaped plates 61 into the corresponding limiting grooves 66 to fix the position of the U-shaped plates 61. Then rotate the threaded rod 62. Since the threaded rod 62 and the U-shaped plates 61 are connected by threads, the rotational motion is converted into the downward linear motion of the threaded rod 62. The pressure plate 63 connected to its lower surface moves downward accordingly until the pressure plate 63 presses smoothly on the product. Continue to tighten the screw, and the pressure plate 63 will generate a downward force to press the product firmly on the base 4.

[0036] refer to Figure 6 Temperature sensors 71 are embedded in the center and both sides of the upper surface of the base 4, which can monitor the temperature of multiple points on the base 4 in real time. Based on the real-time temperature data of these three points, the temperature uniformity of the entire heating area can be accurately determined. Multiple plate-shaped ceramic heaters 72 are embedded in the top of the inner cavity of the base 4. The plate-shaped ceramic heaters 72 have a fast thermal response speed and can quickly reach the set temperature, reducing the heat conduction path and further improving the heating efficiency and temperature control response speed. An S-shaped cooling channel 73 is opened at the bottom of the inner cavity of the base 4. The S-shaped channel increases the contact area and contact time between the coolant and the base 4, thereby improving the heat dissipation efficiency of the base 4.

[0037] The electrical components mentioned in this article are all connected to the external main controller and 220V AC mains power through transformers. The main controller can be a conventional known device such as a computer, which is well known to those skilled in the art. Therefore, those skilled in the art can clearly obtain the corresponding usage effect through the technical solution provided by this utility model.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
