[0047] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0048] like Figures 1 to 7 As shown, the bonding head driving device in the embodiment of the present application includes a frame 1, a first vibration reduction mechanism 2, a second vibration reduction mechanism 3, a first translation mechanism 4 and a second translation mechanism 5, wherein:
[0049] The first vibration reduction mechanism 2 is arranged on the frame 1 .
[0050] The first translation mechanism 4 includes a first slide rail 41, a first drive module 42, a first sliding seat 43 and a second slide rail 44, wherein the first slide rail 41 is arranged on the frame 1 along a first horizontal direction (for example, the X-axis direction in the figure), the first sliding seat 43 is slidably connected to the first slide rail 41, the fixed part of the first drive module 42 is arranged on the first vibration damping mechanism 2, the movable part of the first drive module 42 is connected to the first sliding seat 43, the first drive module 42 is used to drive the first sliding seat 43 to slide along the first slide rail 41, the second slide rail 44 is arranged on the first sliding seat 43 along a second horizontal direction perpendicular to the first horizontal direction (for example, the Y-axis direction in the figure), and the second slide rail 44 is used for sliding connection of the bonding head.
[0051] The second vibration reduction mechanism 3 is arranged on the frame 1 .
[0052] The second translation mechanism 5 includes a third slide rail 51, a second drive module 52, a second sliding seat 53 and a fourth slide rail 54, wherein the third slide rail 51 is arranged on the frame 1 along the second horizontal direction, the second sliding seat 53 is slidably connected to the third slide rail 51, the fixed part of the second drive module 52 is arranged on the second vibration damping mechanism 3, the movable part of the second drive module 52 is connected to the second sliding seat 53, the second drive module 52 is used to drive the second sliding seat 53 to slide along the third slide rail 51, the fourth slide rail 54 is arranged on the second sliding seat 53 along the first horizontal direction, and the fourth slide rail 54 is used for sliding connection of the bonding head.
[0053] Since the bond head is slidably connected to the second slide rail 44 and the fourth slide rail 54 at the same time. When the first driving module 42 drives the first sliding seat 43 to slide along the first slide rail 41 in the first horizontal direction, the bond head slides along the fourth slide rail 54 driven by the first sliding seat 43, thereby realizing position adjustment in the first horizontal direction. When the second driving module 52 drives the second sliding seat 53 to slide along the third slide rail 51 in the second horizontal direction, the bond head slides along the second slide rail 44 driven by the second sliding seat 53, thereby realizing position adjustment in the second horizontal direction. That is, the bond head driving device in the embodiment of the present application can drive the bond head to translate along the first horizontal direction and the second horizontal direction, thereby realizing flexible adjustment of the position of the bond head on the horizontal plane.
[0054] In particular, since the fixing part of the first driving module 42 is arranged on the first vibration reduction mechanism 2, the vibration generated when the first driving module 42 drives the first sliding seat 43 to slide in the first horizontal direction is reduced by the first vibration reduction mechanism 2. Since the fixing part of the second driving module 52 is arranged on the second vibration reduction mechanism 3, the vibration generated when the second driving module 52 drives the second sliding seat 53 to slide in the second horizontal direction is reduced by the second vibration reduction mechanism 3. In addition, the first vibration reduction mechanism 2 and the second vibration reduction mechanism 3 also play a role in delaying the contact time between the first driving module 42 and the second driving module 52 and the equipment frame, thereby reducing the impact force of the first driving module 42 and the second driving module 52 on the equipment frame. The bond head driving device of the embodiment of the present application is used to implement the translational drive of the bond head, which can reduce the vibration of the bond head and ultimately improve the bonding accuracy of the bond head.
[0055] like Figure 5 As shown, optionally, the first vibration reduction mechanism 2 includes a fifth slide rail 21, a first mounting seat 22 and a first magnetic damping assembly 23, wherein: the fifth slide rail 21 is arranged on the frame 1 along the first horizontal direction. The first mounting seat 22 is slidably connected to the fifth slide rail 21, and the fixed component of the first driving module 42 is fixedly mounted on the first mounting seat 22. The first magnetic damping assembly 23 includes a first magnetic seat 231 and a first magnetic core 232, wherein the first magnetic seat 231 is fixedly mounted on the frame 1 and is located on the first side of the first mounting seat 22, the first magnetic seat 231 has a first magnetic field, and the first magnetic core 232 is fixedly connected to the first side wall of the first mounting seat 22 and is located in the first magnetic field. When the first mounting seat 22 slides along the fifth slide rail 21, the first magnetic damping assembly 23 generates a damping force opposite to the sliding direction of the first mounting seat 22.
[0056] When the first driving module 42 drives the first sliding seat 43 to slide along the first slide rail 41, the movable part of the first driving module 42 applies a reaction force to the fixed part of the first driving module 42, and the fixed part of the first driving module 42 and the first mounting seat 22 slide in the opposite direction along the fifth slide rail 21 under the push of the reaction force. At the same time, the first magnetic core 232 slides in the opposite direction synchronously with the first mounting seat 22, and cuts the first magnetic field in the first magnetic seat 231, so that the first magnetic damping assembly 23 generates a damping force opposite to the sliding direction of the first mounting seat 22, thereby offsetting the force of the first sliding seat on the frame, and finally reducing the vibration of the equipment.
[0057] like Figure 5As shown, optionally, the first driving module 42 includes a first motor, wherein a stator 421 of the first motor is fixedly mounted on the first mounting seat 22, and a mover 422 of the first motor is fixedly mounted on the first sliding seat 43. That is, the stator 421 of the first motor constitutes a fixed part of the first driving module 42, and the mover 422 of the first motor constitutes a movable part of the first driving module 42.
[0058] Optionally, a first damping channel for the first magnetic core 232 to pass through is formed in the first magnetic seat 231, and the first magnetic field is formed in the first damping channel. The first magnetic core 232 is configured to move in the first damping channel along the direction of the magnetic flux lines cutting the first magnetic field to generate eddy currents.
[0059] When the first magnetic core 232 slides in the opposite direction synchronously with the first mounting seat 22, it travels in the first damping channel and moves along the direction of the magnetic flux lines that cut the first magnetic field, thereby generating eddy currents. According to Lenz's law, the magnetic field generated by the eddy currents always hinders the movement of the first magnetic core 232 in the magnetic field, thereby generating a damping force opposite to the sliding direction of the first mounting seat 22.
[0060] like Figure 5 and Figure 6 As shown, optionally, the first vibration reduction mechanism 2 further includes a first counterweight block 24 , and the first counterweight block 24 is connected to the second side wall of the first mounting seat 22 .
[0061] Since the first magnetic core 232 is connected to the first side wall of the first mounting seat 22, the first counterweight 24 is arranged on the second side wall of the first mounting seat 22 so that the side walls of the first mounting seat 22 are subjected to stable force, thereby improving the sliding stability of the first mounting seat 22 and further reducing the vibration of the first sliding seat 43.
[0062] Optionally, the bonding head driving device in the embodiment of the present application further includes a first displacement measuring component 6 , and the first displacement measuring component 6 includes a first grating scale arranged on the first mounting seat 22 and a first reading head arranged on the first sliding seat 43 .
[0063] The first grating ruler and the first reading head cooperate with each other to achieve accurate measurement of the movement stroke of the first sliding seat 43 in the first horizontal direction, thereby ensuring that the first driving module 42 can implement accurate control of the movement stroke of the first sliding seat 43 in the first horizontal direction.
[0064] like Figure 7As shown, optionally, the second vibration reduction mechanism 3 includes a sixth slide rail 31, a second mounting seat 32 and a second magnetic damping assembly 33, wherein: the sixth slide rail 31 is arranged on the frame 1 along the second horizontal direction. The second mounting seat 32 is slidably connected to the sixth slide rail 31, and the fixing component of the second driving module 5 is fixedly mounted on the second mounting seat 32. The second magnetic damping assembly 33 includes a second magnetic seat 331 and a second magnetic core 332, wherein the second magnetic seat 331 is fixedly mounted on the frame 1 and is located on the first side of the second mounting seat 32, the second magnetic seat 331 has a second magnetic field, and the second magnetic core 332 is fixedly connected to the first side wall of the second mounting seat 32 and is located in the second magnetic field. When the second mounting seat 32 slides along the sixth slide rail 31, the second magnetic damping assembly 33 generates a damping force opposite to the sliding direction of the second mounting seat 32.
[0065] When the second driving module 52 drives the second sliding seat 53 to slide along the third slide rail 51, the movable part of the second driving module 52 applies a reaction force to the fixed part of the second driving module 52, and the fixed part of the second driving module 52 and the second mounting seat 32 slide in the opposite direction along the sixth slide rail 31 under the push of the reaction force. At the same time, the second magnetic core 332 slides in the opposite direction synchronously with the second mounting seat 32, and cuts the second magnetic field in the second magnetic seat 331, so that the second magnetic damping assembly 33 generates a damping force in the opposite direction of the sliding direction of the second mounting seat 32, which can offset the force of the second sliding seat on the frame, and finally reduce the vibration of the equipment.
[0066] like Figure 7 As shown, optionally, the second driving module 52 includes a second motor, wherein a stator 521 of the second motor is fixedly mounted on the second mounting seat 32, and a mover 522 of the second motor is fixedly mounted on the second sliding seat 53. That is, the stator 521 of the second motor constitutes a fixed part of the second driving module 52, and the mover 522 of the second motor constitutes a movable part of the second driving module 52.
[0067] Optionally, a second damping channel for the second magnetic core 332 to pass through is formed in the second magnetic seat 331, and the second magnetic field is formed in the second damping channel. The second magnetic core 332 is configured to move in the first damping channel along the direction of the magnetic flux lines cutting the first magnetic field to generate eddy currents.
[0068] When the second magnetic core 332 slides synchronously in the opposite direction with the second mounting seat 32, it travels in the second damping channel and moves along the direction of the magnetic flux lines that cut the second magnetic field, thereby generating eddy currents. According to Lenz's law, the magnetic field generated by the eddy currents always hinders the movement of the second magnetic core 332 in the magnetic field, thereby generating a damping force opposite to the sliding direction of the second mounting seat 32.
[0069] Specifically, the first magnetic core 232 and the second magnetic core 332 can be made of antimagnetic materials such as copper and silver. In addition, the eddy current generated by the first magnetic core 232 will eventually be converted into the internal energy of the first magnetic core 232, thereby also consuming a portion of the kinetic energy of the first mounting base 22; the eddy current generated by the second magnetic core 332 will eventually be converted into the internal energy of the second magnetic core 332, thereby also consuming a portion of the kinetic energy of the second mounting base 32. Secondly, the damping force generated by the first magnetic core 232 and the second magnetic core 332 can suppress the peak value of the equipment vibration and reduce the force transmitted to the equipment frame by the first drive module 42 and the second drive module 52.
[0070] Continue to refer Figure 7 As shown, optionally, the second vibration reduction mechanism 3 further includes a second counterweight block 34, and two second counterweight blocks 34 are respectively fixedly connected to the two ends of the second magnetic core 332. By configuring the second counterweight blocks 34 at the two ends of the second magnetic core 332, the stability of the second magnetic core 332 during movement can be improved.

[0072] The second grating ruler and the second reading head cooperate with each other to achieve accurate measurement of the movement stroke of the second sliding seat 53 in the first horizontal direction, thereby ensuring that the first driving module 42 can implement accurate control of the movement stroke of the first sliding seat 43 in the first horizontal direction.
[0073] The embodiment of the present application further provides a bonding device, which includes a bonding head driving device and a bonding head of any of the above embodiments, wherein: the bonding head is slidably connected to the second slide rail 44 and the fourth slide rail 54. When the first driving module 42 drives the first sliding seat 43 to slide along the first slide rail 41, the bonding head slides in the first horizontal direction along the fourth slide rail 54. When the second driving module 52 drives the second sliding seat 53 to slide along the third slide rail 51, the bonding head slides in the second horizontal direction along the second slide rail 44.
