The waste glue cup 145 is located on one side of the cleaning belt 141 and is used to store waste glue sprayed from the dispensing valve device 11. The dispensing valve device 11 can first move above the waste glue cup 145 and spray a certain amount of residual glue and waste glue into the waste glue cup 145. Then, the dispensing valve device 11 moves again above the cleaning belt 141, and its nozzle contacts the cleaning belt 141. The movement of the cleaning belt 141 or the movement of the nozzle achieves wiping and cleaning of the nozzle. This improves the dispensing accuracy and quality of the dispensing valve device 11.

[0030] The weighing device 15 includes a weighing body and a weighing plate 151 above the weighing body. The weighing body can be understood as a device body with a weighing sensor that can realize the weighing function. The dispensing valve device 11 moves above the weighing plate 151 and sprays a set amount of glue onto the weighing plate 151 according to the set program. The weighing body can then measure the weight of the sprayed glue to verify the amount of glue sprayed by the dispensing valve device 11.

[0031] In this embodiment, the dispensing valve device 11, cleaning device 14, and weighing device 15 are all electrically connected to the same control device, which controls the various operations of the dispensing valve device 11, cleaning device 14, and weighing device 15. For example, during the weighing process of the weighing device 15, the weighing device 15 can transmit the weighing data to the control device.

[0032] Additionally, it should be noted that the glue spraying measurement on the weighing plate 151 can be performed multiple times. The control device can subtract the weight before glue spraying from the weight after glue spraying to obtain the weight of each glue spraying.

[0033] Please refer to Figure 2 In this embodiment, the cleaning device 14 further includes a cleaning support block 142, which is disposed below a section of cleaning material belt 141 between the take-up roller and the discharge roller. When the nozzle of the dispensing valve device 11 descends and contacts the cleaning material belt 141, the cleaning material belt 141 will also contact the cleaning support block 142.

[0034] In this embodiment, the cleaning support block 142 is made of an elastic material, such as rubber, silicone, or polyurethane. The cleaning support block 142 is detachably mounted on a fixing plate 143, allowing for disassembly and replacement of the cleaning support block 142.

[0035] In this embodiment, the cleaning support block 142 is provided with a recess 1421 that is compatible with the nozzle of the dispensing valve device 11. When the nozzle of the dispensing valve device 11 descends and contacts the cleaning material belt 141, it will press the cleaning material belt 141 into the recess 1421, so that the cleaning material belt 141 can form a certain wrapping around the nozzle, thereby improving the wiping and cleaning effect of the cleaning material belt 141 on the nozzle.

[0036] In this embodiment, an installation plate 144 is detachably mounted on the auxiliary platform 13, and a waste glue cup 145 is detachably mounted on the installation plate 144 so that the waste glue cup 145 can be removed for cleaning.

[0037] The mounting plate 144 is provided with a mounting groove for mounting the waste glue cup 145. Flared grooves 1441 are provided on both sides of the mounting groove, extending through the top surface of the mounting plate 144. The flared grooves 1441 facilitate the user's placement and removal of the waste glue cup 145.

[0038] In this embodiment, an easy-tear film is attached to the top surface of the weighing plate 151. The dispensing valve device 11 sprays adhesive onto the easy-tear film on the weighing plate 151. When a certain amount of adhesive is sprayed, the easy-tear film can be peeled off and a new easy-tear film can be attached.

[0039] Please refer to Figure 1The high-quality circuit board dispensing equipment of this embodiment may further include a film loading / unloading gripper 152, a film supply box 153, and a waste film box 154 disposed on the auxiliary platform 13. The film supply box 153 and the waste film box 154 are both located on one side of the weighing plate 151, and the film loading / unloading gripper 152 is movable above the weighing plate 151, the film supply box 153, and the waste film box 154. The film loading / unloading gripper 152 can tear off the easy-tear film after spraying glue and place it into the waste film box 154, and can also grab new easy-tear film from the film supply box 153 and reattach it to the weighing plate 151.

[0040] The bottom end of the film loading / unloading gripper 152 is provided with at least three suction cups 1521. For example, three suction cups 1521 are arranged in a triangular pattern, or four suction cups 1521 are arranged in a square pattern. The suction cups 1521 can grip multiple points around the easy-tear film and stably hold the easy-tear film.

[0041] In this embodiment, the top surface of the weighing plate 151 may also be provided with a support groove for placing the easy-tear film, so that the easy-tear film can be more accurately attached to the weighing plate 151.

[0042] Before dispensing, the high-quality circuit board dispensing equipment of this invention can control the dispensing valve device 11 to move above the waste glue cup 145, and spray a certain amount of residual glue and waste glue into the waste glue cup 145. Then, the dispensing valve device 11 moves above the cleaning material belt 141, and the nozzle of the dispensing valve device 11 contacts the cleaning material belt 141. The cleaning material belt 141 moves or the nozzle moves to wipe and clean the nozzle.

[0043] Then, the dispensing valve device 11 is moved above the weighing plate 151 and sprays a set amount of glue onto the weighing plate 151 according to the set program. The weighing body can then measure the weight of the sprayed glue. The weighing device 15 transmits the weighing data to the control device. The control device verifies whether there is a difference between the actual amount of glue sprayed by the dispensing valve device 11 and the amount of glue sprayed preset in the program, or whether the difference is within the normal range.

[0044] After the cleaning and weighing operations described above, the dispensing valve device 11 can perform precise dispensing operations.

[0045] This preferred embodiment of the high-quality circuit board dispensing equipment can store residual and waste glue sprayed from the dispensing valve device in a waste glue cup, wipe the nozzle of the dispensing valve device with a cleaning belt, and weigh the glue sprayed from the dispensing valve device through a weighing device to verify the amount of glue sprayed, thereby improving the dispensing accuracy and quality of the dispensing equipment.

[0046] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
