Description

Technical Field

[0001] The invention relates to the technical field of electronic manufacturing, in particular to a multi-directional pressure-bonding pressure head structure. Background Art

[0002] Thermal bonding is a common thermal compression bonding technology. Its principle is to bond electronic components (such as IC chips) to substrates (such as silicon-based OLED panels) through a press head under high temperature and high pressure. This process forms a strong physical and electrical connection between the pins or contact points of the chip and the electrical connection points of the substrate through heating and pressing.

[0003] The traditional bonding process usually adopts the bonding method of a single chip or FPC, and each station can only complete the bonding of one chip. However, with the continuous improvement of product integration, the bonding method of a single chip can no longer meet the demand. For the situation where multiple chips need to be bonded at the same time, the traditional process must use multiple separate stations to complete the bonding of each chip separately. This not only makes the equipment layout complicated, but also the equipment cost is high, and the production space occupied is also large, which significantly increases the production cost. At present, the traditional bonding head usually adopts a straight-line design, and can only bond one IC at a time. With the changes in product requirements, a single head form can no longer meet the needs of bonding multiple chips in multiple directions at the same time, which limits the flexibility and efficiency of the process to a certain extent. Therefore, the traditional bonding process faces problems such as complex layout, expensive equipment, and large floor space under the bonding requirements of multiple chips, and urgently needs to be improved and optimized.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a multi-directional pressure joint pressure head structure, which has the following beneficial effects:

[0018] 1. The multi-directional press-bonding head structure is configured by a press head customization module. The press head customization module can flexibly configure the style and quantity of the press head according to the needs, so that a single station can complete the bonding of multiple chips at the same time, avoiding the need for multiple stations and complex equipment layout in traditional processes, significantly improving work efficiency, and reducing equipment cost and floor space.

[0019] 2. The multi-directional pressure joint pressure head structure uses the pressure head customized module mechanism setting. Through the cooperation of the arc-shaped positioning block and the fastening bolts, the pressure head is further tightly fitted with the connection kit and the pressure temperature sensing mechanism through the extrusion of the fastening bolts after the initial positioning, ensuring the stable position of the pressure head and the precise contact of the temperature sensor, and improving the positioning accuracy and working reliability.

[0020] 3. The multi-directional pressure bonding pressure head structure uses the pressure head customized module mechanism setting, and the close contact between the pressure head and the temperature sensor realizes the precise adjustment of the temperature control system to ensure the temperature stability during the bonding process. The optimization of the temperature control effect helps to improve the consistency and stability of the product, avoid quality problems caused by temperature fluctuations, and ensure a high-precision production process.

[0021] 4. The multi-directional press-fitting head structure is equipped with a dust removal mechanism. The rotating jet pipe drives the hollow barrel to rotate through the reaction force to achieve the rotating jet of airflow, which increases the dust removal range and ensures that the workpiece surface is dust-free. This rotating airflow effectively avoids the problem of insufficient local cleaning that may exist in static jetting, and also reduces the impact of airflow on the workpiece, protecting precision parts. The cleaning mechanism ensures that the bottom of the press head is always clean through the cooperation of the friction plate and the cleaning part, avoiding the influence of impurities on the bonding accuracy.

[0022] 5. The multi-directional pressure joint pressure head structure uses the cleaning mechanism setting, rotating cleaning mechanism and precise positioning design to improve the automation level of the equipment and reduce the need for manual intervention. The cleaning part automatically retracts through the action of the torsion spring and does not affect the normal operation of the pressure head. Through these designs, the operation of the equipment becomes more intelligent, the complexity of manual operation is reduced, and the stability and reliability of production are improved.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 6A multi-directional bonding head structure includes a bonding head lifting and fixing module 1, which is used to adjust the height of the bonding head to ensure that the bonding head can accurately contact the workpiece and complete the required pressure application. It provides a lifting function for the bonding head to ensure the stability and precise positioning of the bonding head in different operation stages; a bonding head heating mechanism 2 is used to control the temperature of the bonding head or the workpiece to ensure that the required temperature conditions are met during the bonding process to optimize the Bonding process. The bonding head heating mechanism 2 can soften or adjust the physical properties of the workpiece by heating the bonding head or the substrate to improve the bonding effect; a bonding head temperature sensing mechanism 3 is used to monitor and adjust the temperature of the workpiece or the bonding head in real time to ensure that the temperature during the bonding process is within a preset range. The temperature sensing mechanism 3 can accurately detect temperature changes and feed back to the control system so as to adjust the temperature of the pressing and heating mechanism 2 as needed, thereby ensuring process stability and quality; the pressure head customization module mechanism 4 is used to freely replace modules of different styles and quantities, and can flexibly adapt to different process requirements, especially when multiple chips are Bonded at the same time, the pressure head customization module mechanism 4 can customize the style and quantity of the pressure head according to the design requirements of the product, so as to achieve the bonding of multiple chips at a single station. Through flexible pressure head configuration, multiple chips can be processed at the same time at one station, which significantly improves work efficiency and reduces the need for multiple stations and complex equipment layout in traditional processes.This improvement can not only simplify the equipment structure and reduce the equipment cost, but also save production space, thereby effectively reducing production costs; the dust removal mechanism 5 is used to blow and remove dust from the workpiece before pressing, in order to ensure that the surface of the workpiece is clean and to prevent dust or impurities from affecting the Bonding process. Dust or impurities will lead to poor crimping, affecting the bonding quality of the chip and the substrate, and may even lead to equipment failure or product failure. By effectively removing dust before Bonding, the Bonding quality can be improved, the accurate alignment and firm connection of the chip can be ensured, the defect rate can be reduced, and the reliability and process efficiency of the product can be improved; the cleaning mechanism 6 is used to clean the pressure head customization module mechanism 4 after the pressing operation is completed, to ensure that there is no residue, dust or adhered material on the surface of the pressure head, so as to prevent these pollutants from affecting the Bonding quality of the workpiece during the next operation. By regularly cleaning the pressure head, the pressure head can be maintained. Maintain the efficient operation of the equipment, avoid the degradation of pressure head performance, damage or Bonding failure due to accumulated dirt, thereby improving product quality and production efficiency, and extending the service life of the equipment. The pressing heating mechanism 2 is fixedly connected to the bottom of the pressing lifting and fixing module 1, and can provide a stable heating function for the pressure head to ensure that the required temperature is reached during the Bonding process, thereby improving the crimping quality. Heating helps to soften the surface of the bonding material or IC chip, improve the bonding effect, and prevent poor Bonding due to low temperature. The pressing temperature sensing mechanism 3 is arranged on the outer wall of the pressing heating mechanism 2, which is used to monitor and adjust the temperature of the pressing heating mechanism 2 in real time. Through the feedback of the pressing temperature sensing mechanism 3, it can ensure that the temperature is kept within the ideal range, thereby avoiding excessively high or low temperatures from having a negative impact on the workpiece or Bonding quality. The pressing head customization module mechanism 4 is arranged at the bottom of the pressing temperature sensing mechanism 3.

[0032] The pressure head customized module mechanism 4 includes a connecting kit 41, an insertion port 42 is provided on the inner wall of the connecting kit 41, a pressure head member 43 is plugged on the inner wall of the connecting kit 41, one end of a spring 44 is fixedly connected to the inner wall of the pressure head member 43, the other end of the spring 44 is fixedly connected to an arc-shaped positioning block 45, the outer wall of the arc-shaped positioning block 45 is fixedly connected to one end of a telescopic rod 46, the other end of the telescopic rod 46 is fixedly connected to the inner wall of the pressure head member 43, a fastening bolt 47 is provided on the inner wall of the connecting kit 41, and the inner wall of the connecting kit 41 and the pressure head member 43 are fixedly connected. The temperature sensing mechanism 3 is sleeved, and the fastening bolt 47 is used to press and fix the pressure head 43. When the pressure head 43 needs to be connected, the arc-shaped positioning block 45 on the pressure head 43 is pressed, so that the arc-shaped positioning block 45 compresses the spring 1 44, and then the connection pressure head 43 of the appropriate style and number is inserted into the connection kit 41, so that the arc-shaped positioning block 45 is plugged into the plug interface 42 in the connection kit 41, and the connection pressure head 43 is preliminarily positioned, and then the fastening bolt 47 is turned to squeeze the pressure head 43, so that the pressure head 43 and the connection kit 41 are connected. The pressure-sensing mechanism 3 is tightly fitted, and the pressure head piece 43 squeezes the pressure-temperature sensing mechanism 3. The pressure head piece 43 is re-positioned and the connection kit 41 is also tightly fitted with the pressure-temperature sensing mechanism 3. While ensuring its tight fit with the connection kit 41, it not only improves the connection stability, but also makes the pressure head piece 43 produce extrusion contact with the pressure-temperature sensing mechanism 3 to ensure the accuracy of temperature sensing. Through the above design, the connection kit 41 and the pressure-temperature sensing mechanism 3 are firmly combined, which can improve the positioning accuracy and working reliability of the pressure head piece 43, and at the same time optimize the temperature control effect of the pressure bonding process, improve production efficiency and product quality, and can flexibly adapt to different process requirements. In particular, when multiple chips are bonded at the same time, the pressure head customization module mechanism 4 can customize the style and quantity of the pressure head according to the design requirements of the product, so as to realize the bonding of multiple chips at a single station at the same time. Through flexible pressure head configuration, multiple chips can be processed at the same station at the same time, which significantly improves work efficiency and reduces the need for multiple stations and complex equipment layout in traditional processes. This improvement can not only simplify the equipment structure and reduce the equipment cost, but also save production space, thereby effectively reducing production costs. Four slots are provided on the inner wall of the connecting kit 41 for plugging in the pressure head 43.

[0033] The dust removal mechanism 5 includes a driving motor 51, which is fixedly connected to the inner wall of the pressure heating mechanism 2. The output shaft of the driving motor 51 is fixedly connected to the main shaft 52, and the outer wall of the main shaft 52 is fixedly connected to the fan blade 53. The inner wall of the pressure heating mechanism 2 is fixedly connected to a connecting ring 54, and the inner wall of the connecting ring 54 is rotatably connected to a hollow barrel 55. The inner wall of the hollow barrel 55 is fixedly connected to an oblique jet pipe 56. There are two oblique jet pipes 56, and the two oblique jet pipes 56 are arranged in a circular array. When the fan blade 53 outputs wind force and sprays it through the two oblique jet pipes 56, the two oblique jet pipes 56 drive the hollow barrel 55 to rotate under the action of the reaction force, so that the airflow ejected by the rotating two oblique jet pipes 56 removes dust from the workpiece, realizing the rotary injection of the airflow. This design enables the airflow ejected from the two oblique jet pipes 56 to cover It covers a larger dust removal range, effectively cleans the workpiece surface comprehensively, ensures that the workpiece surface is dust-free, improves the reliability of the Bonding process and the quality of the finished product, and reduces the impact of the airflow directly on the workpiece surface through rotary jetting, avoids damage to the workpiece due to excessive airflow, improves the dust removal efficiency while ensuring operational safety and protection of precision workpieces. The rotating jet increases the dust removal effect, because the rotary jet forms an airflow field with a larger coverage range, which can clean different parts of the workpiece in an all-round way, avoiding the problem of incomplete local cleaning that may occur with static jetting. Through the rotary motion, the direction of the jet changes continuously, which can more effectively blow away the dust and particles on the workpiece surface and recessed areas. At the same time, the kinetic energy superposition effect of the rotary jet can enhance the impact and diffusion capacity of the airflow, further improving the dust removal efficiency and thoroughness.

[0034] The cleaning mechanism 6 includes a connecting strip 61 and a body connecting member 63. One end of the connecting strip 61 is fixedly connected to the bottom of the hollow barrel 55, and the other end of the connecting strip 61 is fixedly connected to a friction plate 1 62. The body connecting member 63 is connected to the body so that the body connecting member 63 will not move up and down with the pressure lifting and fixing module 1 and the pressure heating mechanism 2. The outer wall of the body connecting member 63 is fixedly connected to an annular positioning member 64, and the inner wall of the annular positioning member 64 is rotatably connected to a connecting shaft 65. The top of the connecting shaft 65 is fixedly connected to a friction plate 2 66, and the bottom of the connecting shaft 65 is fixedly connected to a long condition 67. The cleaning member 68 is hinged on the side of the long condition 67 away from the connecting shaft 65. The outer wall of the cleaning member 68 is fixedly connected to the bottom of the connecting shaft 65. One end of the torsion spring 69 is fixedly connected, and the other end of the torsion spring 69 is fixedly connected to the outer wall of the long condition 67. The connecting shaft 65 passes through the inner wall of the friction plate 1 62. The cleaning member 68 is located at the bottom of the pressure head member 43. When the hollow barrel 55 rotates, the hollow barrel 55 drives the friction plate 1 62 to rotate through the connecting strip 61. The friction plate 1 62 drives the friction plate 2 66 to rotate through the friction force. The friction plate 2 66 drives the connecting shaft 65 to rotate. The connecting shaft 65 drives the long condition 67 and the cleaning member 68 to rotate. The cleaning member 68 cleans the bottom of the pressure head member 43. When the pressure lifting and fixing module 1 and the pressure heating mechanism 2 are pressed downward, the pressure heating mechanism 2 drives the connecting ring 54 and the hollow barrel 55 to move downward. 55 drives the connecting strip 61 and the friction plate 1 62 to move downward, so that the friction plate 1 62 moves downward relative to the friction plate 2 66, and the pressure head customized module mechanism 4 is also driven downward by the present pressure heating mechanism 2 to move, and the pressure head member 43 moves downward. Since the machine body connecting member 63 is fixedly connected to the machine body, the connecting shaft 65, the friction plate 2 66, the long condition 67, the cleaning member 68, and the torsion spring 69 connected to the machine body connecting member 63 will not move, so that the pressure head member 43 presses the cleaning member 68 downward, so that the cleaning member 68 rotates and retracts to the inner side of the pressure head member 43 under the action of the torsion spring 69, and will not affect the downward pressing of the pressure head member 43, and the bottom of the pressure head member 43 is effectively cleaned by the rotating cleaning member 68. The cleaning mechanism 6 ensures that the pressing head 43 remains clean during multiple uses, thereby avoiding the situation where the pressing head 43 is affected by the adhesion of impurities and the impact of the Bonding accuracy. When the pressing head 43 is pressed downward, the cleaning member 68 can automatically retract into the inner side of the pressing head 43 under the action of the torsion spring 69, without affecting the normal pressing operation of the pressing head 43. At the same time, the rotating structure of the cleaning mechanism 6 ensures the stable working state of the cleaning member 68, making the cleaning effect more thorough. This design optimizes the cleaning process, improves the automation level of the equipment and the Bonding accuracy, helps to solve the process problems caused by incomplete cleaning in the traditional Bonding process, and further improves production efficiency and product quality.

[0035] In summary, with this multi-directional pressure-joined pressure head structure, when it is necessary to connect the pressure head piece 43, the arc-shaped positioning block 45 on the pressure head piece 43 is pressed, so that the arc-shaped positioning block 45 compresses the spring 1 44, and then the connection pressure head piece 43 of the appropriate style and number is inserted into the connection kit 41, so that the arc-shaped positioning block 45 is plugged into the plug interface 42 in the connection kit 41, and the connection pressure head piece 43 is preliminarily positioned, and then the fastening bolt 47 is rotated to squeeze the pressure head piece 43, so that the pressure head piece 43 and the connection kit 41 are tightly fitted, and at the same time, the pressure head piece 43 squeezes the pressure-temperature sensing mechanism 3, and while the pressure head piece 43 is positioned for the second time, the connection kit 41 is also tightly fitted with the pressure-temperature sensing mechanism 3, ensuring that it is tightly fitted with the connection kit 41, which not only improves the connection stability, but also makes the pressure head piece 4 3 produces extrusion contact with the pressure-temperature sensing mechanism 3 to ensure the accuracy of temperature sensing. Through the above design, the connection kit 41 and the pressure-temperature sensing mechanism 3 are firmly combined, which can improve the positioning accuracy and working reliability of the pressure head 43, and optimize the temperature control effect of the pressure bonding process, improve production efficiency and product quality, and can flexibly adapt to different process requirements. Especially in the case of bonding of multiple chips at the same time, the pressure head customization module mechanism 4 can customize the style and quantity of the pressure head according to the design requirements of the product, so as to achieve the bonding of multiple chips at a single station at the same time. Through flexible pressure head configuration, multiple chips can be processed at the same station at the same time, significantly improving work efficiency and reducing the need for multiple stations and complex equipment layout in traditional processes. This improvement can not only simplify the equipment structure and reduce the equipment cost, but also save production space, thereby effectively reducing production costs.

[0036] When the fan blade 53 outputs wind force and sprays it through the two oblique jet pipes 56, the two oblique jet pipes 56 drive the hollow barrel 55 to rotate under the action of the reaction force, so that the airflow sprayed by the two oblique jet pipes 56 can remove dust from the workpiece, and realize the rotary jetting of the airflow. This design enables the airflow sprayed by the two oblique jet pipes 56 to cover a larger dust removal range, effectively clean the surface of the workpiece comprehensively, ensure the dust-free surface of the workpiece, and improve the reliability of the Bonding process and the quality of the finished product. At the same time, the impact of the airflow directly acting on the surface of the workpiece is reduced by rotary jetting, and damage to the workpiece caused by excessive airflow is avoided. While improving the dust removal efficiency, it ensures the safety of operation and the protection of precision workpieces. The rotating jet increases the dust removal effect, because the rotating jet forms an airflow field with a larger coverage range, which can clean different parts of the workpiece in an all-round way, avoiding the problem of incomplete local cleaning that may occur in static jetting. Through the rotating motion, the direction of the jet changes continuously, which can more effectively blow away the dust and particles on the surface of the workpiece and the concave area. At the same time, the kinetic energy superposition effect of the rotating jet can enhance the impact and diffusion capacity of the airflow, and further improve the dust removal efficiency and thoroughness.

[0037] When the hollow barrel 55 rotates, the hollow barrel 55 drives the friction plate 1 62 to rotate through the connecting strip 61, and the friction plate 1 62 drives the friction plate 2 66 to rotate through the friction force, and the friction plate 2 66 drives the connecting shaft 65 to rotate, and the connecting shaft 65 drives the long condition 67 and the cleaning member 68 to rotate, and the cleaning member 68 cleans the bottom of the pressure head member 43. When the pressure lifting and fixing module 1 and the pressure heating mechanism 2 are pressed downward, the pressure heating mechanism 2 drives the connecting ring 54 and the hollow barrel 55 to move downward, and the hollow barrel 55 drives the connecting strip 61 and the friction plate 1 62 to move downward, so that the friction plate 1 62 moves downward relative to the friction plate 2 66, and the pressure head customized module mechanism 4 is also driven downward by the pressure heating mechanism 2, and the pressure head member 43 moves downward. Since the body connecting member 63 is fixedly connected to the body, the connecting shaft 65, the friction plate 2 66, the long condition 67, the cleaning member 68, and the torsion spring 69 connected to the body connecting member 63 will not move. The head piece 43 presses the cleaning piece 68 downward, so that the cleaning piece 68 rotates and retracts into the inner side of the pressing head piece 43 under the action of the torsion spring 69, which will not affect the pressing downward of the pressing head piece 43. The rotating cleaning piece 68 can effectively clean the bottom of the pressing head piece 43 to ensure that the pressing head piece 43 remains clean during multiple uses, thereby avoiding the situation where the pressing head piece 43 is affected by the attachment of impurities and the impact of the Bonding accuracy. When the pressing head piece 43 is pressed downward, the cleaning piece 68 can automatically retract into the inner side of the pressing head piece 43 under the action of the torsion spring 69, which will not affect the normal pressing operation of the pressing head piece 43. At the same time, the rotating structure of the cleaning mechanism 6 ensures the stable working state of the cleaning piece 68, making the cleaning effect more thorough. This design optimizes the cleaning process, improves the degree of automation of the equipment and the accuracy of Bonding, helps to solve the process problems caused by incomplete cleaning in the traditional Bonding process, and further improves production efficiency and product quality.
