However, the existing feeding device often transmits the airflow sensor with the filter side facing upward to the automated wire bonding equipment during feeding. This causes the automated wire bonding equipment to frequently report errors, and workers are often required to correct the error reports.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A feeding device for an airflow sensor comprises a base, a vibration component and a feeding tray, wherein the vibration component is arranged on the base, and the feeding tray is drivingly connected to the vibration component; a collecting cavity is arranged in the feeding tray, a feeding track is arranged on the periphery of the collecting cavity, a buffer track is arranged at the discharge end of the feeding track, a dividing plate is arranged at the discharge end of the buffer track, the dividing plate is connected to the outer wall of the feeding tray, and a plurality of screening grooves are distributed in an annular manner on the dividing plate; a discharge track assembly is arranged at the discharge end of the dividing plate.

[0008] In the airflow sensor feeding device, the dividing plate is detachably connected to a limiting current strip, and one end of the limiting current strip extends toward the discharge end of the buffer track.

[0009] In the airflow sensor feeding device, the track surface of the buffer track is inclined downwardly outwardly, and a baffle is provided at the edge of the buffer track; the plate surface of the dividing plate is inclined downwardly inwardly.

[0010] In the airflow sensor feeding device, the discharge track assembly includes a correction track and a dividing track, the correction track is arranged at the discharge end of the dividing plate, the dividing track is arranged at the discharge end of the correction track, and the dividing track is provided with an in-place detection assembly, and the in-place detection assembly is electrically connected to the vibration assembly; the in-place detection assembly is used to detect the in-place status of the airflow sensor.

If one side of a circuit board of the airflow sensor faces upward, the airflow sensor uses a smooth filter surface to smoothly pass through the dividing plate, and enters a discharge track component to prepare for feeding to an automated wire welding device. If one side of a circuit board of the airflow sensor faces downward, when the airflow sensor passes through the dividing plate, due to the presence of solder joints and electrical components on the circuit board, one side of the circuit board is a concave-convex surface. When the circuit board passes through the screening trough, a raised portion on the circuit board will be stuck in the screening trough, thereby causing interference between the airflow sensor and the dividing plate. When the airflow sensor on the buffer track is pushed toward the dividing plate, the interfering airflow sensor will be pushed toward the outside of the dividing plate, so that it will re-enter the feeding tray.

DETAILED DESCRIPTION

[0021] The utility model provides an air flow sensor feeding device and an automated wire welding device thereof. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples.

[0022] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "middle", "inner side", "outer side", etc. are directions or positional relationships of the present invention based on the drawings, which are only for the convenience of describing the present invention and simplifying the description. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0023] See also Figures 1 to 4 The utility model provides an airflow sensor feeding device, including a base 1, a vibration component 2 and a feeding tray 3, wherein the vibration component 2 is arranged on the base 1, and the feeding tray 3 is transmission-connected with the vibration component 2; a collecting cavity 31 is arranged in the feeding tray 3, a feeding track 32 is arranged on the periphery of the collecting cavity 31, a buffer track 4 is arranged at the discharging end of the feeding track 32, a dividing plate 5 is arranged at the discharging end of the buffer track 4, the dividing plate 5 is connected to the outer wall of the feeding tray 3, and a plurality of screening grooves 51 are distributed in an annular manner on the dividing plate 5; a discharging track component 6 is arranged at the discharging end of the dividing plate 5.

[0024] In actual use, the airflow sensor feeding device needs to be installed on the automatic wire welding equipment and used in conjunction with the various workstations of the automatic wire welding equipment; when in use, the semi-finished product of the airflow sensor is pre-filled into the collecting cavity 31, and the vibration component 2 is used to drive the feeding plate 3 to perform the vibration feeding action, so that the airflow sensor is transported along the feeding track 32 to the buffer track 4. When the airflow sensor passes through the dividing plate 5, the dividing plate 5 uses the screening trough 51 to screen the airflow sensor. If the circuit board side of the airflow sensor faces upward, the airflow sensor uses the smooth filter surface to smoothly pass through the dividing plate 5 and enter the discharge track component 6 to prepare for feeding the automatic wire welding equipment. One side of the circuit board of the device faces downward, and when the airflow sensor passes through the dividing plate 5, due to the presence of solder joints and electrical components on the circuit board, one side of the circuit board is a concave-convex surface. When the circuit board passes through the screening slot 51, the raised part of the circuit board will be stuck in the screening slot 51, thereby causing interference between the airflow sensor and the dividing plate 5. When the airflow sensor of the cache track is pushed toward the dividing plate 5, the interfering airflow sensor will be pushed to the outside of the dividing plate 5, so that it will re-enter the feeding tray 3. In this way, the screening action of the airflow sensor is realized, the accuracy of the airflow sensor loading is improved, the error frequency of the automatic wire welding equipment is reduced, and the working stability of the automatic wire welding equipment is improved.

[0025] It should be noted that the vibration component 2 is the structure of the vibration component 2 in the existing vibration loading tray, and the specific structure and working principle are all existing technologies and will not be repeated here.

[0027] like Figures 1 to 4 As shown, further, a recovery tray 7 is arranged on the periphery of the feed tray 3, and a recovery groove 71 is formed between the recovery tray 7 and the feed tray 3, and the recovery groove 71 is connected with the collecting cavity 31; the recovery groove 71 is located below the dividing plate 5, and the recovery groove 71 extends toward the outside of the dividing plate 5; when in use, when the airflow sensor on the dividing plate 5 falls, it will fall into the recovery groove 71, and the recovery groove 71 will be used to return the airflow sensor to the collecting cavity 31, thereby forming a cyclic loading action; in addition, expanding the recovery groove 71 toward the outside of the dividing plate 5 can ensure that the airflow sensor enters the recovery groove 71 when it falls, thereby improving the stability of the airflow sensor during recovery.

[0028] like Figures 1 to 4As shown, further, the dividing plate 5 is detachably connected to a limiting strip 52, and one end of the limiting strip 52 extends toward the discharge end of the buffer track 4; the limiting strip 52 is utilized to limit the discharge amount of the buffer track 4, so that the airflow sensors in the buffer track 4 can enter the dividing plate 5 one by one, thereby improving the screening accuracy of the dividing plate 5; in addition, the limiting strip 52 can be selected according to the shape of the airflow sensor to adjust the opening of the discharge end of the buffer track 4.

[0029] It should be noted that the current limiting strip 52 and the dividing plate 5 are connected by existing fasteners such as bolts, screws, and threaded rods.

[0031] like Figures 1 to 4 As shown, further, the discharge track assembly 6 includes a correction track 61 and a material distribution track 62, the correction track 61 is arranged at the discharge end of the material distribution plate 5, the material distribution track 62 is arranged at the discharge end of the correction track 61, and the material distribution track 62 is provided with an in-place detection assembly 63, and the in-place detection assembly 63 is electrically connected to the vibration assembly 2; the in-place detection assembly 63 is used to detect the in-place status of the airflow sensor; the airflow sensor on the material distribution plate 5 is introduced into the material distribution track 62 by using the correction track 61, and when the airflow sensor enters After entering the dividing track 62, the in-place detection component 63 will detect the entry amount of the airflow sensor. When the number of airflow sensors in the dividing track 62 reaches a preset threshold, the in-place detection component 63 will feedback a pause signal to the vibration component 2, so that the feeding tray 3 temporarily stops the feeding action. When the in-place detection component 63 detects that the airflow sensors in the dividing track 62 are reduced to a certain amount, the in-place detection component 63 will feedback a start signal to the vibration component 2, so that the feeding tray 3 continues to perform the feeding action, thereby completing the quantitative feeding action of the airflow sensor feeding device.

[0032] like Figures 1 to 4As shown, further, an optical path slot 621 is obliquely arranged on the material distribution track 62; the in-place detection component 63 includes a light emitting part 631 and a receiving part 632, and the light emitting part 631 and the receiving part 632 are respectively arranged at the two ends of the optical path slot 621; the receiving part 632 is electrically connected to the vibration component 2; when the airflow sensor passes through the optical path slot 621, the infrared light of the light emitting part 631 will be blocked by the airflow sensor, at this time, the receiving part 632 will not receive the optical signal, and the material distribution track 62 continues to perform the feeding action during this period, and the feeding tray 3 stops performing the loading action, when the receiving part 632 receives the optical signal of the light emitting part 631 again, that is, the airflow sensor at the end of the material distribution track 62 has passed the optical path slot 621, at this time, the receiving part 632 feeds back a start signal to the vibration component 2, so that the correction track 61 feeds the material to the material distribution track 62; in this way, dynamic fixed feeding is realized, and the stability of the airflow sensor feeding device during feeding is improved.

[0033] It should be noted that the light emitting unit 631 and the receiving unit 632 are existing sensor structures such as light sensors and optical fiber sensors. The specific structures and working principles are all existing technologies and will not be described in detail here.

[0034] like Figures 1 to 4 As shown, further, the vibration component 2 includes a vibrator 21 and a vibration disk 22, the vibrator 21 is arranged on the base 1, and the vibrator 21 is transmission connected to the feeding tray 3 through the vibration disk 22; when in use, the vibrator 21 drives the feeding tray 3 to vibrate and feed the material through the vibration disk 22, so as to realize the feeding action of the feeding tray 3 to the airflow sensor.

[0035] It should be noted that the vibrator 21 and the vibration plate 22 are existing vibration platform structures, and their specific structures and working principles are all existing technologies, which will not be described in detail here.

[0036] The utility model also provides an automatic wire bonding device, comprising the airflow sensor feeding device as described above.

[0037] To sum up, when in use, the vibration component 2 is used to drive the feeding tray 3 to perform the vibration feeding action, so that the airflow sensor is transported along the feeding track 32 to the buffer track 4.
