[0005] A hood having a first receiving cavity, wherein the hood is provided with a first air outlet communicating with the first receiving cavity;

[0006] A crystal fixing mechanism, housed in the first housing cavity;

[0018] Optionally, the die bonding machine further comprises a mounting plate for mounting the driving motor, and the motor cover is disposed on the mounting plate to limit the second receiving cavity.

[0019] Optionally, the air guide duct is configured as a rubber hose.

[0020] In the technical solution of the utility model, the crystal bonding machine includes a machine cover, a crystal bonding mechanism, a driving motor, a motor cover, a heat dissipation duct and a fan. The machine cover has a first receiving chamber and a first air outlet connected to the first receiving chamber. The crystal bonding mechanism is received in the first receiving chamber, and the driving motor drives and connects the crystal bonding mechanism; the motor cover is received in the first receiving chamber, the motor cover has a second receiving chamber for receiving the driving motor, and the motor cover is provided with a second air outlet connected to the first receiving chamber and the second receiving chamber; the heat dissipation duct has a third air outlet connected to the second receiving chamber, and a fourth air outlet connected to the machine cover; the crystal bonding machine also includes a fan for guiding the air in the heat dissipation duct to flow from the third air outlet to the fourth air outlet. In this way, the first receiving chamber is provided to facilitate the installation of the crystal bonding mechanism, and a first air outlet connected to the first receiving chamber is provided to enable air outside the hood to enter the first receiving chamber through the first air outlet. The drive motor is installed in the second receiving chamber of the motor outer cover to reduce the heat generated by the drive motor from being dissipated into the first receiving chamber. The second air outlet is provided on the motor outer cover to facilitate the air in the first receiving chamber to enter the second receiving chamber. A heat dissipation duct and a fourth air outlet are provided to enable the second receiving chamber to communicate with the outside of the hood, so that air can circulate between the first air outlet and the fourth air outlet. When the crystal bonding machine is dissipating heat, air outside the hood enters the first receiving chamber through the first air outlet. The heat generated by the drive motor is discharged from the first receiving chamber and the second receiving chamber through the second air outlet to absorb the heat generated by the drive motor. The air that has absorbed the heat is blown by the fan and flows through the third air outlet to the fourth air outlet to be discharged from the die bonding machine to achieve heat dissipation for the drive motor. Because the heat is directly conducted by the air from the inside of the hood to the fourth air outlet and discharged to the outside of the hood, the heat generated by the drive motor will not stay in the first receiving chamber and the second receiving chamber, thus avoiding the problem that the heat stays near the drive motor and cannot be discharged in time, causing the temperature of the drive motor and the die bonding mechanism inside the hood to be too high, and effectively ensuring the stable operation of the drive motor and the die bonding mechanism. It is worth mentioning that the fan can also blow the dust on the outside of the drive motor into the heat dissipation duct and be discharged to the fourth air outlet together with the air, thus achieving the dust removal effect on the drive motor and avoiding the normal operation of the drive motor being affected by dust accumulation.

[0031] At present, a crystal bonding machine includes a machine cover, a crystal bonding mechanism, a driving motor, and a fan, and the machine cover has a first receiving chamber. The driving motor is drivingly connected to the crystal bonding mechanism. The crystal bonding mechanism, the driving motor, and the fan are all arranged in the first receiving chamber, and the fan is arranged toward the driving motor so that the airflow flows through the driving motor, thereby dissipating the heat of the driving motor. After the airflow flows through the driving motor, the temperature rises. However, the high-temperature airflow will accumulate in the first receiving chamber and is difficult to dissipate outside the machine cover, which makes the temperature of the crystal bonding mechanism accommodated in the first receiving chamber higher, thereby reducing the operating efficiency of the crystal bonding mechanism. To this end, the utility model proposes a crystal bonding machine, which is intended to make the high-temperature airflow after flowing through the driving motor easily dissipate outside the machine cover, so that the temperature of the driving motor and the crystal bonding mechanism will not be too high, thereby improving the operating efficiency of the driving motor and the crystal bonding mechanism.

[0032] Reference Figures 1 to 2In one embodiment of the utility model, the crystal bonding machine includes a machine cover 100, a crystal bonding mechanism, a driving motor 200, a motor cover 300, a heat dissipation duct and a fan 600. The machine cover 100 has a first receiving chamber 110 and a first air outlet 120 connected to the first receiving chamber 110. The crystal bonding mechanism is received in the first receiving chamber 110, and the driving motor 200 drives and connects the crystal bonding mechanism; the motor cover 300 is received in the first receiving chamber 110, and the motor cover 300 has a second receiving chamber 310 for receiving the driving motor 200. The motor cover 300 is provided with a second air outlet 320 connected to the first receiving chamber 110 and the second receiving chamber 310; the heat dissipation duct has a third air outlet 410 connected to the second receiving chamber 310, and a fourth air outlet 510 connected to the machine cover 100; the crystal bonding machine also includes a fan 600 for guiding the air in the heat dissipation duct to flow from the third air outlet 410 to the fourth air outlet 510. In this way, the first receiving chamber 110 is provided to facilitate the installation of the crystal bonding mechanism, and the first air outlet 120 connected to the first receiving chamber 110 is provided so that the air outside the hood 100 can enter the first receiving chamber 110 through the first air outlet 120. The drive motor 200 is installed in the second receiving chamber 310 of the motor housing 300 to reduce the heat generated by the drive motor 200 from being dissipated into the first receiving chamber 110. The second air outlet 320 is provided on the motor housing 300 to facilitate the air in the first receiving chamber 110 to enter the second receiving chamber 310. The heat dissipation duct and the fourth air outlet 510 are provided to make the second receiving chamber 310 communicate with the outside of the hood 100 so that the air can circulate between the first air outlet 120 and the fourth air outlet 510. When the crystal bonding machine is dissipating heat, the air outside the hood 100 passes through the first air outlet 120. 0 enters the first receiving chamber 110, and then enters the second receiving chamber 310 through the second air outlet 320 to absorb the heat generated by the drive motor 200. The air that has absorbed the heat is blown by the fan 600 and flows through the third air outlet 410 to the fourth air outlet 510 to be discharged from the die bonding machine to achieve heat dissipation for the drive motor 200. Because the heat is directly conducted by the air from the inside of the hood 100 to the fourth air outlet 510 and discharged to the outside of the hood 100, the heat generated by the drive motor 200 will not stay in the first receiving chamber 110 and the second receiving chamber 310, thereby avoiding the problem that the heat stays near the drive motor 200 and cannot be discharged in time, resulting in the problem of excessive temperature of the drive motor 200 and the die bonding mechanism located inside the hood 100, and effectively ensuring the stable operation of the drive motor 200 and the die bonding mechanism. It is worth mentioning that the fan 600 can also blow the dust outside the drive motor 200 into the heat duct and discharge it to the fourth air outlet 510 together with the air, thereby achieving the dust removal effect on the drive motor 200 and preventing the normal operation of the drive motor 200 from being affected by dust accumulation.

[0033] In other embodiments, the structure of the heat dissipation system of the crystal bonding machine also includes other cooling devices. Other auxiliary cooling devices can be arranged near the drive motor 200 or the crystal bonding mechanism. Optionally, a liquid cooling system can be arranged inside the machine cover 100 to enhance the cooling and heat dissipation effect of the drive motor 200 to adapt to a higher temperature working environment and a high-intensity equipment operation environment.

[0034] Optionally, in one embodiment, the heat dissipation duct includes an air duct 400 having a third air outlet 410 and an air passage 500 having a fourth air outlet 510, the air duct 400 is connected to the air passage 500, and the air passage 500 is arranged in the hood 100. In this way, the hot air in the drive motor 200 enters the air duct 400 through the third air outlet 410, and is guided to the air passage 500 by the air duct 400, and finally flows to the fourth air outlet 510 through the air passage 500 and is discharged to the outside of the hood 100, so as to achieve heat dissipation of the drive motor 200; the hot air in and near the drive motor 200 is conducted through the air duct 400 and the air passage 500, and is not dissipated and stays in the first receiving chamber 110, so that the heat stays in the drive motor 200 and the hood 100, and the influence of the heat on the drive motor 200 and the die bonding mechanism is weakened.

[0035] In other embodiments, the heat dissipation duct may have various structural forms, and the heat dissipation duct may also be an integrally formed pipe, with the air outlet of the heat dissipation duct being arranged outside the hood 100 to discharge hot air to the outside of the hood 100 .

[0036] Optionally, in one embodiment, the fan 600 is accommodated in the second accommodation chamber 310, and the fan 600 is accommodated in the second accommodation chamber 310, so that the fan 600 forms forced convection from natural convection in the motor housing 300, directly acts on the drive motor 200, and the fan 600 accelerates the flow of air, so that the heat generated by the drive motor 200 is continuously absorbed by the air and quickly brought to the fourth air outlet 510 to be discharged, thereby improving the heat dissipation effect of the drive motor 200. In other embodiments, the fan 600 can also be arranged in the first accommodation chamber 110, or even outside the housing 100, as long as it can accelerate the flow rate of air in the air duct 400 and the air passage 500.

[0037] Optionally, in one embodiment, the fan 600 is disposed above the drive motor 200, and the third air outlet 410 is located above the drive motor 200. In this way, the heat generated by the drive motor 200 will increase the temperature of the surrounding air, and the air with a higher temperature will expand and rise. Therefore, the third air outlet 410 is disposed above the drive motor 200, so that the hot air can enter the air duct 400 through the third air outlet 410 and be quickly discharged according to its own expansion and rise, which is beneficial to the heat dissipation of the drive motor 200; the fan 600 is disposed above the drive motor 200, so that the expanded and rising hot air can be blown to the third air outlet 410, and quickly discharged through the air duct 400 and the air passage 500, which is beneficial to the heat dissipation of the drive motor 200. In other embodiments, the fan 600 can be disposed in many ways, and the fan 600 can also be fixed on the side wall of the motor housing 300, and the third air outlet 410 can also be opened on the peripheral side of the motor housing 300.

[0038] Optionally, in one embodiment, a plurality of second air vents 320 are provided. In this way, a plurality of second air vents 320 are provided, which increases the flow rate of air in contact with the heat in the motor housing 300, speeds up the absorption of heat from the motor housing 300, and improves the heat dissipation effect of the drive motor 200. In other embodiments, the number of second air vents 320 can be set in many ways, and only one second air vent 320 can be set on the motor housing 300.

[0039] Optionally, in one embodiment, a plurality of second air vents 320 are arranged at intervals on the outer peripheral surface of the motor housing 300. In this way, the hot air in the second receiving chamber 310 rises due to expansion, and enters the air duct 400 from the third air vent 410 disposed above the drive motor 200 to be discharged, and is not easily dissipated from the second air vents 320 opened on the outer peripheral surface of the motor housing 300, thereby avoiding the problem that the heat in the second receiving chamber 310 is dissipated from the second air vents 320 to the first receiving chamber 110, resulting in the accumulation of heat in the first receiving chamber 110 and causing the temperature of the equipment in the first receiving chamber 110 to rise. In other embodiments, the second air vents 320 may be arranged in other situations, and only one second air vent 320 may be opened on the outer peripheral surface of the motor housing 300, so that the air in the first receiving chamber 110 can be guided into the second receiving chamber 310, and the heat in the second receiving chamber 310 is not easily dissipated to the first receiving chamber 110.

[0040] Optionally, in one embodiment, a plurality of fourth air vents 510 are provided. In this way, a plurality of fourth air vents 510 are provided, which increases the amount of hot air discharged, so that the hot air in the first receiving cavity 110 can be guided to the fourth air vent 510 to be discharged from the hood 100 more quickly, thereby improving the efficiency of discharging the heat generated by the drive motor 200 and enhancing the heat dissipation effect of the drive motor 200. In other embodiments, only one fourth air vent may be provided to discharge the hot air in the hood.

[0041] Optionally, in one embodiment, a plurality of fourth air vents 510 are all disposed at the bottom of the housing 100. In this way, the fourth air vents 510 are disposed at the bottom of the housing 100, and when the hot air in the second receiving chamber 310 is discharged, the hot air discharged from the fourth air vents 510 is prevented from being sprayed on surrounding instruments or workers, causing damage to the instruments or human bodies. At the same time, the dust blown out of the second receiving chamber 310 can fall from the air passage 500 to the fourth air vents 510 according to its own gravity, which is conducive to the discharge of dust.

[0042] In other embodiments, other structures may be provided at the fourth air outlet 510 to help discharge hot air and dust. Optionally, a shutter structure may be provided at the fourth air outlet 510 to cover the fourth air outlet 510. Providing the shutter structure at the fourth air outlet 510 is beneficial to guiding the air, so as to discharge the hot air in the air passage 500 to the outside of the hood 100 more quickly. Filter cotton may also be added at the fourth air outlet 510 to absorb dust discharged from the second containing chamber 310, so as to collect the discharged dust. The dust cleaning work at the fourth air outlet 510 can be completed by replacing the filter cotton, so as to avoid the discharged dust accumulating at the fourth air outlet 510 and causing blockage, or being directly discharged to the ground outside the hood 100 and dirtying the ground.

[0043] Optionally, in one embodiment, the die bonding machine further includes a mounting plate 130 for mounting the drive motor 200, and the motor housing 300 is disposed on the mounting plate 130 to limit the second receiving chamber 310. In this way, the mounting plate 130 is connected to the motor housing 300 to form the second receiving chamber 310, and the drive motor 200 is mounted on the mounting plate 130 to achieve support and installation of the drive motor 200. The second receiving chamber 310 seals the heat generated by the drive motor 200 and dissipates it to the outside of the hood 100 through the heat dissipation duct, thereby preventing the heat generated by the drive motor 200 from being dissipated to the first receiving chamber 110 and being accumulated and unable to be discharged in time, resulting in the drive motor 200 and the die bonding mechanism inside the hood 100 being too high in temperature, thereby causing damage to the drive motor 200 and the die bonding mechanism. In other embodiments, the drive motor 200 can also be directly mounted on the hood 100, eliminating the need for the mounting plate 130, as long as the drive motor 200 can be supported and installed.

[0044] Optionally, in one embodiment, the air duct 400 is configured as a rubber hose. The air duct 400 is configured as a rubber hose, which has good elasticity and elongation, and can change the direction of the duct to avoid the setting of the crystal fixing mechanism inside the hood 100 without interfering with the setting of the crystal fixing mechanism, thereby improving the utilization rate of the internal space of the hood 100. In other embodiments, the air duct 400 can also be a pipe of other materials, or a metal pipe made of steel, as long as it can achieve the function of guiding the air.

[0045] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
