[0002] Existing automated wire bonding equipment for airflow sensors typically uses pneumatic grippers to unload finished airflow sensors. However, due to the small size of airflow sensors, the pneumatic grippers are prone to not gripping them firmly, leading to the airflow sensors easily detaching during the unloading process.

The top-feeding mechanism has multiple top support parts that cooperate with the placement slots. A transverse movement mechanism is provided on one side of the output end of the feeding conveyor line along its length. A lifting mechanism, which can move up and down towards the feeding dies, is driven to the transverse movement mechanism. A clamping part is provided at the output end of the lifting mechanism, and multiple clamping slots corresponding to the placement slots are provided at the ends of the clamping parts. Telescopic parts that can extend and retract downwards are provided within the clamping slots.

[0007] In the airflow sensor unloading device, the top material mechanism includes a lifting assembly and a lifting frame. The lifting frame is connected to the lifting assembly in a transmission manner, and all the top support parts are located at the top of the lifting frame.

[0008] In the airflow sensor feeding device, an airbag is provided at the end of the top support, a first air passage is provided in the top support and communicates with the airbag, a second air passage is provided in the lifting frame and communicates with the first air passage, and an air nozzle assembly is provided at the outlet of the second air passage.

[0009] In the airflow sensor unloading device, the lifting assembly includes a base, a lifting screw is provided on the top of the base, a lifting motor is provided at the bottom of the base and is drivenly connected to the lifting screw, lifting guide rods are provided on both sides of the lifting screw, linear bearing assemblies are provided on both sides of the lifting frame and are slidably connected to the lifting guide rods, and a nut assembly is provided on one side of the lifting frame and is drivenly connected to the lifting screw.

[0010] In the airflow sensor feeding device, the output end of the lifting mechanism is connected to a lifting seat, all the telescopic parts are connected to the lifting seat through a disassembly seat, the clamping part is detachably connected to the bottom of the disassembly seat, the top of the clamping part is provided with a feeding hole communicating with the clamping groove, and the output end of the telescopic part is located in the feeding hole.

[0011] In the airflow sensor feeding device, the clamping part is provided with arc-shaped clamping plates on both sides of the clamping groove, and the end edges of the arc-shaped clamping plates are arc-shaped.

[0012] In the airflow sensor feeding device, an elastic support block is provided between two arc-shaped clamping plates between adjacent clamping slots, and the two sides of the elastic support block abut against the arc-shaped clamping plates on both sides respectively.

[0013] In the airflow sensor unloading device, the two sides of the disassembly base are respectively provided with snap-fit ​​parts, the two bottom sides of the disassembly base are respectively provided with guide rods, the two sides of the clamping part are respectively provided with snap-fit ​​grooves that are snapped and connected to the snap-fit ​​parts, and the two top sides of the clamping part are respectively provided with through holes that cooperate and connect with the guide rods.

[0016] Beneficial effects:

[0017] This invention provides an airflow sensor unloading device. In use, when the feeding mold reaches above the top material feeding mechanism, the feeding conveyor line stops its conveying action. During the stop interval, the top material feeding mechanism rises towards the bottom of the feeding mold, causing each top support to extend upwards into the placement groove until the airflow sensor is lifted upwards. The clamping part needs to be pre-moved above the feeding mold via a transverse mechanism and pressed against the feeding mold by a lifting mechanism until the opening of the clamping groove is pressed against the placement groove. When the airflow sensor is lifted by the top support, its top will be inserted into the clamping groove, thus achieving material transfer. All airflow sensors are simultaneously transferred to the clamping part. Then, the transverse mechanism transfers the clamping part to the unloading area. During unloading, the telescopic part pushes the airflow sensor out of the clamping groove to complete the unloading action. The top material feeding mechanism, in conjunction with the clamping part, achieves the material transfer action of the airflow sensor. The deformation principle of the clamping part is used to clamp and fix the airflow sensor, improving the stability of the airflow sensor during the transfer process. Attached Figure Description

Detailed Implementation

[0027] This invention provides an airflow sensor feeding device and its automated wire bonding equipment. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0028] In the description of this invention, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this invention based on the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0029] Please see Figures 1 to 8This invention provides an airflow sensor unloading device, including a feeding conveyor line 1. A chute 11 is provided along the length of the feeding conveyor line 1. Multiple feeding molds 2 are distributed on the chute 11. Multiple placement slots (not shown in the figure) are provided on the top surface of each feeding mold 2. A top support hole (not shown in the figure) is provided at the bottom of each placement slot. A top-feeding mechanism 3, which can extend and retract into the chute 11, is provided below the output end of the feeding conveyor line 1. Multiple top support portions 31 are provided on the top-feeding mechanism 3 and cooperate with the placement slots. A transverse movement mechanism 4 is provided on one side of the output end of the feeding conveyor line 1 along its length. A lifting mechanism 5, which can rise and fall towards the feeding molds 2, is driven and connected to the transverse movement mechanism 4. A clamping portion 6 is provided at the output end of the lifting mechanism 5. Multiple clamping slots 61, corresponding to the placement slots, are provided at the end of each clamping slot 61. Telescopic portions 62, which can extend and retract downwards, are provided within each clamping slot 61.

[0030] In actual use, the airflow sensor 7 after wire bonding is transported by the feeding mold 2. The feeding mold 2 moves along the transmission direction of the chute 11 of the feeding conveyor line 1. When the feeding mold 2 reaches above the top material mechanism 3, the feeding conveyor line 1 stops its transmission action. During the stop gap, the top material mechanism 3 rises towards the bottom of the feeding mold 2, so that each top support 31 extends into the placement groove from bottom to top until the airflow sensor 7 is lifted upward. The clamping part 6 needs to be slid to the top of the feeding mold 2 in advance by the transverse mechanism 4, and press against the feeding mold 2 under the action of the lifting mechanism 5 until the groove opening of the clamping groove 61 presses against the placement groove. Above the placement slot, when the airflow sensor 7 is lifted by the top support 31, the top of the airflow sensor 7 will be inserted into the clamping slot 61, thereby achieving the material transfer action, so that all the airflow sensors 7 are transferred to the clamping part 6 at the same time. Then, the lateral movement mechanism 4 is used to transfer the clamping part 6 to the unloading area. During unloading, the telescopic part 62 is used to push the airflow sensor 7 out of the clamping slot 61 to complete the unloading action. The top support mechanism 3 and the clamping part 6 are used to realize the transfer action of the airflow sensor 7. The deformation principle of the clamping part 6 is used to clamp and fix the airflow sensor 7, which improves the stability of the airflow sensor 7 during the transfer process.

[0031] In this embodiment, the feeding conveyor line 1 includes a transfer slide rail 12, a chute 11 located on the transfer slide rail 12, and a plurality of push block assemblies 13 that can be opened and closed vertically are arranged below the chute 11 along its length. All the push block assemblies 13 are connected by a connecting rod 14. A plurality of bases 15 are arranged at the bottom of the transfer slide rail 12 along its length, and guide sliders 16 that are slidably connected to the connecting rods 14 are arranged on the bases 15. A lead screw motor assembly 17 is arranged at one end of the transfer slide rail 12, and one end of the connecting rod 14 is drivenly connected to the lead screw motor assembly 17 through a lead screw slider 18. In use, the guide slider 16 guides the connecting rod 14 to slide, so that the connecting rod... 14 can perform linear sliding along the length of the transfer slide rail 12. In addition, the connecting rod 14 is driven to perform linear sliding by the lead screw motor assembly 17 in conjunction with the lead screw slider 18. When the push block assembly 13 can be transferred to the rear of the feeding mold 2, the push block assembly 13 enters the open state, so that its top extends into the slide groove 11. When the connecting rod 14 drives the push block assembly 13 to move towards the feeding mold 2, the push block assembly 13 will push one side of the feeding mold 2, so that it slides along the length of the slide groove 11, thereby realizing the transfer action of the feeding mold 2. When the feeding mold 2 is transferred to the position, the push block assembly 13 will close downward and return to the bottom of the slide groove 11 and complete the reset action to prepare for the next feeding action.

[0032] In this embodiment, the push block assembly 13 includes a mounting base (not shown in the figure), the top of the mounting base is provided with a hinge groove (not shown in the figure), a push slider (not shown in the figure) is hinged in the hinge groove, and an electric telescopic rod (not shown in the figure) is provided in the mounting base below the push slider; the electric telescopic rod is used to adjust the ejection height of the push slider; in use, the lifting height of the push slider is controlled by the electric telescopic rod, thereby controlling the extension and retraction of the push slider in the slide groove 11, so that the push slider can realize the pushing action of the feeding mold 2.

[0033] like Figures 1 to 8 As shown, the top material mechanism 3 further includes a lifting assembly 32 and a lifting frame 33. The lifting frame 33 is connected to the lifting assembly 32 in a transmission manner, and all the top support parts 31 are located at the top of the lifting frame 33. In use, the lifting assembly 32 is used to drive the lifting frame 33 to make vertical lifting movements, thereby adjusting the extension amount of the top support part 31, that is, controlling the top support part 31 to push out the airflow sensor 7.

[0034] like Figures 1 to 8As shown, further, an airbag portion 34 is provided at the end of the top support portion 31. A first air passage 311 communicating with the airbag portion 34 is provided in the top support portion 31, and a second air passage communicating with the first air passage 311 is provided in the lifting frame 33. An air nozzle assembly 35 is provided at the outlet of the second air passage. In use, the airbag portion 34 is connected to an external air source through the first air passage 311, the second air passage, and the air nozzle assembly 35. When the top support portion 31 approaches the bottom of the airflow sensor 7, the external air source inflates the airbag portion 34 until the airbag portion 34 is in contact with the airflow sensor. The bottom of the airflow sensor 7 contacts the air bladder 34, and the top support 31 pushes the air bladder 34 upward when it contacts the air bladder 34. The air bladder 34 then lifts the airflow sensor 7 upward. When the airflow sensor 7 is inserted into the clamping groove 61, the external air source instantly draws the air out of the air bladder 34, causing it to return to a deflated state. This prevents the top support 31 from causing wear to the air bladder 34 when it retracts, thus improving the stability of the air bladder 34 during use. Using the air bladder 34 as a medium to contact the airflow sensor 7 can effectively prevent the top support 31 from damaging the surface of the airflow sensor 7, thus improving the safety of the airflow sensor 7 during material feeding.

[0035] like Figures 1 to 8 As shown, the lifting assembly 32 further includes a base 321, a lifting screw 322 is provided on the top of the base 321, a lifting motor 323 is provided at the bottom of the base 321 and is pulsatorically connected to the lifting screw 322, lifting guide rods 324 are provided on both sides of the lifting screw 322, linear bearing assemblies 331 are provided on both sides of the lifting frame 33 and are slidably connected to the lifting guide rods 324, and a nut assembly 332 is provided on one side of the lifting frame 33 and is pulsatorically connected to the lifting screw 322; in use, the lifting motor 323 drives the lifting frame 33 to perform lifting action using the lifting screw 322, and the lifting frame 33 achieves linear lifting action under the action of the two lifting guide rods 324.

[0036] It should be noted that both the linear bearing assembly 331 and the nut assembly 332 are existing linear bearing structures and lead screw nut structures. Their specific structures and working principles are existing technologies and will not be described in detail here.

[0037] like Figures 1 to 8As shown, further, the output end of the lifting mechanism 5 is connected to a lifting seat 63, and all the telescopic parts 62 are connected to the lifting seat 63 via a disassembly seat 64. The clamping part 6 is detachably connected to the bottom of the disassembly seat 64, and the top of the clamping part 6 is provided with a discharge hole 65 communicating with the clamping groove 61. The output end of the telescopic part 62 is located in the discharge hole 65. In use, the lifting mechanism 5 uses the lifting seat 63 to drive the clamping part 6 and the telescopic part 62 to move up and down synchronously toward the feeding mold 2. When the airflow sensor 7 moves... When the device moves to the unloading area, all telescopic parts 62 will simultaneously extend into the unloading hole 65 until the telescopic parts 62 are fully extended out of the slot of the clamping groove 61, so as to ensure that the airflow sensor 7 is pushed out of the clamping groove 61, making the unloading action of the airflow sensor 7 smoother. In addition, since the clamping groove 61 of the clamping part 6 may have certain deformation after long-term use, the clamping part 6 needs to be replaced regularly. Therefore, by setting the clamping part 6 and the disassembly and assembly base 64 as a disassembly and assembly structure, it is convenient for the staff to replace the clamping part 6 regularly, so as to ensure the stability of the clamping part 6 when clamping.

[0038] It should be noted that the lifting mechanism 5 and the telescopic part 62 can be existing cylinder structures, electric telescopic rod structures, or other mechanisms with telescopic functions. The specific structure and working principle are existing technologies and will not be described in detail here.

[0039] like Figures 1 to 8 As shown, further, the clamping part 6 is provided with arc-shaped clamping plates 66 on both sides of the clamping groove 61, and the end edges of the arc-shaped clamping plates 66 are arc-shaped. When clamping the airflow sensor 7, the airflow sensor 7 is clamped in the clamping groove 61 by utilizing the deformation characteristics of the two arc-shaped clamping plates 66. The arc-shaped end edges of the arc-shaped clamping plates 66 make the insertion action of the airflow sensor 7 smoother. When the ejector mechanism 3 lifts the airflow sensor 7, the airflow sensor 7 will contact the edges of the arc-shaped clamping plates 66 on both sides before entering the clamping groove 61. The arc-shaped edges facilitate the entry of the airflow sensor 7 into the clamping groove 61 and cause the arc-shaped clamping plates 66 on both sides to deform, thereby clamping the airflow sensor 7 in the clamping groove 61.

[0040] In this embodiment, the opening diameter of the clamping groove 61 is smaller than the diameter of the airflow sensor 7; this setting makes the airflow sensor 7 more secure when clamped, and increases the clamping force of the arc-shaped clamping plate 66 on the airflow sensor 7.

[0041] like Figures 1 to 8As shown, further, an elastic support block 67 is provided between the two arc-shaped clamping plates 66 between adjacent clamping slots 61, and the two sides of the elastic support block 67 abut against the arc-shaped clamping plates 66 on both sides respectively; the elastic support block 67 increases the clamping force of the arc-shaped clamping plates 66, so that the arc-shaped clamping plates 66 can hold the airflow sensor 7 more securely. In addition, the elastic support block 67 can prevent the arc-shaped clamping plates 66 from being over-deformed and provides a certain support for the arc-shaped clamping plates 66.

[0042] It should be noted that the elastic support block 67 can be a support block structure with elastic properties, such as a polyurethane support block, a rubber support block, or a silicone support block.

[0043] It should be noted that the arc-shaped clamping plate 66 can be an existing PVC clamping plate, PC clamping plate, or other clamping plate structure with certain plastic deformation characteristics.

[0044] like Figures 1 to 8 As shown, further, the disassembly base 64 is provided with snap-fit ​​parts 68 on both sides, and guide rods 69 are provided on both sides of the bottom of the disassembly base 64. The clamping part 6 is provided with snap grooves 610 on both sides that snap-fit ​​with the snap-fit ​​parts 68, and through holes 611 on both sides of the top of the clamping part 6 that cooperate with the guide rods 69. In use, the snap-fit ​​parts 68 and the snap grooves form a quick disassembly and assembly structure between the clamping part 6 and the disassembly base 64, allowing workers to quickly disassemble and assemble the clamping part 6. This also facilitates the regular replacement of the clamping part 6. In addition, the guide rods 69 and through holes 611 facilitate the positioning between the clamping part 6 and the disassembly base 64, making the installation of the clamping part 6 more convenient.

[0045] like Figures 1 to 8As shown, further, the transverse mechanism 4 includes a support frame 41 and a track frame 42 mounted on the support frame 41. A lead screw assembly 43 is arranged within the track frame 42 along its length. A motor assembly 44, which is pulsatorically connected to the lead screw assembly 43, is located at one end of the track frame 42. Sliding grooves 45 are respectively provided at the top and bottom of the track frame 42 along its length. A positioning detection part 46 is located at the top of the track frame 42 above the top material feeding mechanism 3. A sliding seat 51 is provided on the back of the lifting mechanism 5. A slider 52, which is pulsatorically connected to the lead screw assembly 43, is mounted on the sliding seat 51. The slider 52... The sliding seats 51 are provided with guide grooves 53 that are slidably connected to the sliding grooves 45. In use, the motor assembly 44 drives the lead screw assembly 43 to rotate, so that the slider 52 can make linear sliding motion along the length direction of the sliding groove 45, realizing the reciprocating sliding motion of the clamping part 6 between the loading station and the unloading station. The guide grooves 53 and the sliding grooves 45 can improve the stability of the sliding seats 51 during sliding. In addition, the position detection unit 46 detects the sliding position of the sliding seats 51. When the position detection unit 46 detects the position signal of the sliding seats 51, it will feed back to control the motor assembly 44 to stop, so that the clamping part 6 can perform the clamping action.

[0046] It should be noted that the positioning detection unit 46 can be an existing sensor structure such as a positioning sensor or a contact sensor. The specific structure and working principle are existing technologies and will not be described in detail here.

[0047] The present invention also provides an automated wire bonding device, including the airflow sensor feeding device described above.

[0048] In summary, during use, when the feeding mold 2 reaches above the top material mechanism 3, the feeding conveyor line 1 will stop its conveying action. During the stop interval, the top material mechanism 3 rises towards the bottom of the feeding mold 2, causing each top support 31 to extend upwards into the placement groove until the airflow sensor 7 is lifted upwards. The clamping part 6 needs to be pre-moved above the feeding mold 2 via the transverse mechanism 4 and pressed against the feeding mold 2 under the action of the lifting mechanism 5 until the opening of the clamping groove 61 presses against the top of the placement groove. When the airflow sensor 7 is lifted by the top support 31... The top of the airflow sensor 7 will be inserted into the clamping groove 61 to achieve the material transfer action, so that all the airflow sensors 7 are transferred to the clamping part 6 at the same time. Then, the lateral movement mechanism 4 is used to transfer the clamping part 6 to the unloading area. During unloading, the telescopic part 62 is used to push the airflow sensor 7 out of the clamping groove 61 to complete the unloading action. The material lifting mechanism 3 is used in conjunction with the clamping part 6 to realize the material transfer action of the airflow sensor 7. The deformation principle of the clamping part 6 is used to clamp and fix the airflow sensor 7, which improves the stability of the airflow sensor 7 during the transfer process.
