The dispensing valve 44 is used to perform dispensing work on the circuit board 02 on the tooling component 5 located at the dispensing station 610. The first XYZ axis linear module 41 is used to move the position of the dispensing valve 44 and the first gripper cylinder 42 to the dispensing station 610 or the housing loading and first flipping station 620.

[0082] In the above embodiment, preferably, a monitoring camera 45 is also installed on the Z-axis arm of the first XYZ axis linear module 41. The lens of the monitoring camera 45 is positioned directly opposite the outlet end of the dispensing valve 44. The monitoring camera 45 is electrically connected to the monitoring display screen 15, which can monitor the dispensing status in real time and store the monitoring data for easy traceability.

[0083] In the above embodiments, preferably, the dispensing valve 44 is also electrically connected to the dispensing valve controller 14 to achieve precise control of the dispensing valve 44. The dispensing valve 44 in this embodiment includes a pneumatic dispensing valve, a screw dispensing valve, or a spray valve; the dispensing wire diameter of the dispensing valve 44 is 0.3±0.05mm.

[0084] like Figure 19 As shown, in the above embodiment, preferably, the tooling flipping component 7 includes a lifting platform 71, a translation module 72, a slide cylinder 73, a third gripper cylinder 75, and a rotating platform 74; wherein, the lifting platform 71 is disposed on one side of the transmission component 6 corresponding to the secondary flipping station 630, the translation module 72 is placed on the lifting platform 71, and the moving direction of the translation module 72 is parallel to the transmission direction of the transmission component 6, the slide cylinder 73 is placed on the translation module 72, and the slide cylinder 73 can move along a direction perpendicular to the transmission direction of the transmission component 6.

In actual use, by placing the spring clamp 31 on the tensioning cylinder 202, the extension and retraction of the tensioning cylinder 202 drives the clamping plates 313 on both sides of the spring clamp 31 to move to the sides or the middle. When moving to the sides, the clamping plates 313 on both sides compress the spring 312. When moving to the middle, the spring 312 is released, and at the same time, the tooling component 5 placed above the base plate 314 is clamped.

[0087] This invention provides an automatic bonding method for a six-sided flexible connection circuit board for an accelerometer, which is applied to the aforementioned automatic bonding device for the six-sided flexible connection circuit board of an accelerometer, comprising:

[0088] Step S1: Manually place the tooling component 5 onto the tooling loading plate 63, and place the flexible circuit board 02 onto the tooling component 5;

[0089] Specifically, the tooling component 5 is manually picked up and unfolded and placed flat on the tooling loading plate 63. Then, the flexible circuit board 02 is placed into the slot corresponding to the tooling flip plate 51 of the tooling component 5.

[0090] Step S2: The tooling plate 63 is moved to the dispensing station 610 by the transmission component 6, and the dispensing and handling component 4 completes the dispensing work on the circuit board 02 on the tooling component 5.

[0091] Specifically, when the tooling plate 63 carrying the tooling component 5 moves to the dispensing station 610, the blocking cylinder 64 completes the limiting of the tooling plate 63, and the lifting cylinder 65 lifts the tooling plate 63 to get it away from the transmission surface of the transmission component 6. The dispensing and transporting component 4 drives the dispensing valve 44 to move to the dispensing station 610 through the first XYZ linear module 41, and performs uniform dispensing on the circuit board 02 on the tooling component 5 at the station through the dispensing valve 44, and monitors the dispensing status in real time through the monitoring camera 45.

[0092] After dispensing is completed, the lifting cylinder 65 descends to place the loading plate 63 back onto the transmission surface of the transmission component, and the blocking cylinder retracts to allow the loading plate 63 to flow into the next station.

[0093] Step S3: After the dispensing work is completed, the tooling plate 63 is moved to the housing loading and first flipping station 620. The dispensing and handling component 4 clamps the housing 01 supplied by the housing loading component 2 and places it above the circuit board 02. Multiple flipping mechanisms lift upwards to complete the flipping work of the second flip plate 512 and the third flip plate 513 of the tooling component 5, so as to drive the two sides of the circuit board 02 to be pasted onto the housing 01.

[0094] Specifically, the tooling loading plate 63 of the tooling component to be dispensing is moved to the housing loading and first flipping station 620. At this time, the blocking cylinder 64 completes the limiting of the tooling loading plate 63, and the lifting cylinder 65 lifts the tooling loading plate 63 to get it away from the transmission surface of the transmission component 6. The dispensing and handling component 4 drives the first gripper cylinder 42 through the first XYZ linear module 41 to grip the housing 01 supplied by the housing loading component 2, and moves it to the housing loading and first flipping station 620. The housing 01 is placed on the circuit board on the tooling component 5 on the tooling loading plate 63, and is placed at the position of the first flip plate 511 of the tooling component 5. The two flipping cylinders 66 push upward and pass through the through holes on the corresponding tooling loading plate 63 to complete the flipping work of the second flip plate 512 and the third flip plate 513 of the tooling component 5, so as to drive the two sides of the circuit board 02 to be pasted onto the housing 01.

[0095] After the housing is loaded and flipped once, the lifting cylinder 65 descends to place the loading plate 63 back onto the transmission surface of the transmission component, and the blocking cylinder retracts to allow the loading plate 63 to flow into the next station.

[0096] Step S4: The tooling plate 63 moves to the secondary flipping station 630. The tooling flipping component 7 drives the tooling component 5 to rotate 90 degrees twice, completing the flipping work of the fourth flipping plate 514 and the fifth flipping plate 515 of the tooling component 5, so as to drive the other two sides of the circuit board 02 to be pasted onto the housing 01.

[0097] Specifically, the tooling plate 63 of the tooling component 5, which has completed the shell loading and first flip, is moved to the second flip station 630. The blocking cylinder 64 limits the tooling plate 63 and lifts the tooling plate 63 to detach it from the transmission surface of the transmission component 6 by the lifting cylinder 65. The tooling flipping component 7 aligns the rotation axis of the rotating platform with the flipping plate rotation axis 52 and flips the tooling component 5 as a whole by 90°. After the first flip, a second 90-degree flip is performed to complete the flipping work of the fourth flipping plate 514 and the fifth flipping plate 515 of the tooling component 5, so as to drive the other two sides of the circuit board 02 to be pasted onto the shell 01.

[0098] After the second flip is completed, the lifting cylinder 65 descends to place the loading plate 63 back onto the transmission surface of the transmission component, and the blocking cylinder retracts to allow the loading plate 63 to flow into the next station.

[0099] Step S5: The tooling plate 63 moves to the three-fold flipping station 640, and the flipping mechanism lifts upward, completing the flipping operation of the sixth flipping plate 516 of the tooling component 5, so as to drive the last side of the circuit board 02 to be pasted onto the housing 01. (After the flipping and pasting is completed, the tooling components of the housing 01 and the circuit board 02 are as follows...) Figure 6 (as shown);

[0100] Specifically, the tooling plate 63 of the tooling component 5, which is to be flipped twice, moves to the third flipping station 640. At this time, the blocking cylinder 64 limits the tooling plate 63 and lifts the tooling plate 63 by the lifting cylinder 65 to separate it from the transmission surface of the transmission component 6. The folding cylinder 66 lifts it upward and passes through the through hole on the corresponding tooling plate 63 to complete the flipping of the sixth flip plate 516 of the tooling component 5, so as to drive the last side of the circuit board 02 to be pasted onto the housing 01.

[0101] Step S6: The unloading and conveying component 8 grabs the spring clip 31 supplied by the spring clip loading component 3 and places it on the spring clip clamping component 20, and grabs the tooling component 5 at the three-fold flipping station 640 and places it on the spring clip 31 at the spring clip clamping component 20. The spring clip clamping component 20 drives the spring clip 31 to clamp the tooling component 5.

[0102] Specifically, step S6 includes:

[0103] Step S61: The unloading and conveying component 8 grabs the upward first spring clip 31 supplied by the spring clip loading component 3 and places it on the spring clip clamping component 20. After it is placed in place, the unloading and conveying component 8 grabs the tooling component 5 at the three-fold flipping station 640 and places it on the first spring clip 31 at the spring clip clamping component 20. The spring clip clamping component 20 drives the first spring clip 31 to clamp the three sides of the tooling component 5.

[0104] Step S62: The unloading and conveying component 8 grabs the downward-facing second spring clip 31 supplied by the spring clip loading component 3 and places it on the tooling component 5 at the spring clip clamping component 20. The spring clip clamping component 20 drives the second spring clip 31 to clamp the remaining three sides of the tooling component 5.

[0105] Step S7: The unloading and conveying component 8 clamps the tooling component 5, which has completed the clamping operation of the spring clamp 31, from the position of the spring clamp clamping component 20 to the unloading area.

[0106] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
