[0053] Specifically, the x-axis fine adjustment assembly 5, the y-axis fine adjustment assembly 4 and the z-axis fine adjustment assembly 6 are each provided with a back-to-origin photoelectric switch.
[0054] After the dispensing position of the first dispensing assembly 3 is fixed, the position of the first dispensing assembly 3 is taken as a reference, and the second dispensing assembly 7 can be controlled to move left and right, forward and backward and up and down by the x-axis fine adjustment assembly 5, the y-axis fine adjustment assembly 4 and the z-axis fine adjustment assembly 6, so as to realize compensation of different positions of the second dispensing assembly 7 and dispensing on different positions of the workpiece.
[0055] The first dispensing assembly 3 and the second dispensing assembly 7 are subjected to first position correction by the X-axis movement assembly 1, the Z-axis movement assembly and the Y-axis movement assembly, and after the first position correction is completed, the x-axis fine adjustment assembly 5, the y-axis fine adjustment assembly 4 and the z-axis fine adjustment assembly 6 perform second correction on the second dispensing assembly 7. Through the two times of position correction, the dispensing position of the second dispensing assembly 7 can be ensured to be accurate, especially the second dispensing assembly 7 can correct different products during dispensing, and can adapt to different dispensing positions of different workpieces.
[0056] In the embodiment, the first dispensing assembly 3 comprises a first dispensing valve 31, the first dispensing valve 31 is connected to a mounting block 32, the mounting block 32 is connected to a mounting seat 34 through a clamp 33, and the mounting seat 34 is connected to the Z-axis mounting plate 23.
[0057] In the embodiment, as Figure 8 , the second dispensing assembly 7 comprises an adjusting plate 71, the adjusting plate 71 is arranged on the z-direction movable plate 63; a valve mounting block 72, the valve mounting block 72 is movably connected to the adjusting plate 71; a clamping block 73, the clamping block 73 presses the valve mounting block 72 and the adjusting plate 71 tightly; and a second dispensing valve 74, the second dispensing valve 74 is connected to the valve mounting block 72.
[0058] Specifically, the adjusting plate is provided with a positioning hole 75, the clamping block 73 is provided with a positioning groove 76, and a bolt is arranged in the positioning groove 76 and the positioning hole 75 to fix the clamping block 73. The valve mounting block 72 can move on the adjusting plate 71 (in the x direction), and the movement mode can be adjusted manually. After the position adjustment is completed, the fastening bolt is arranged in the positioning groove 76 and screwed into the positioning hole 75 to realize fastening of the mounting block. Through the above structure, manual adjustment of the second dispensing assembly 7 in the x direction can be realized. The above adjustment is generally preliminary adjustment before dispensing operation.
[0059] In the embodiment, as Figure 3 , the first dispensing valve 31 and the second dispensing valve 74 both adopt vertical dispensing, and a liquid level detector is arranged on the side of the first dispensing valve 31 and the second dispensing valve 74.
[0060] Specifically, the glue cylinder holder 77 of the second dispensing valve 74 is arranged obliquely in the Z-axis direction, and the upper end of the glue cylinder holder 77 of the second dispensing valve 74 is away from the glue cylinder holder 77 of the first dispensing valve 31. Since the glue cylinder and the glue cylinder holder 77 have a certain volume, the glue cylinder holder 77 of the second dispensing valve 74 is arranged obliquely to provide more installation space in the x direction, so that the glue outlet positions of the first dispensing valve 31 and the second dispensing valve 74 are closer.
[0061] Specifically, the interval between the first dispensing valve 31 and the second dispensing valve 74 is 30-150mm. Since a plurality of products to be dispensed are generally arranged on the carrier, the first dispensing assembly 3 and the second dispensing assembly 7 need to dispense the same product, and generally two dispensing positions are provided on the same product. Due to the different types and sizes of products, the position of the second dispensing assembly 7 needs to be adjusted according to the dispensing position. Therefore, the minimum gap between the first dispensing valve 31 and the second dispensing valve 74 is 30mm, and the minimum interval between the adjacent two products is generally 60mm. Therefore, the double-valve dispensing mechanism of the utility model can be applied to small carriers or carriers with densely distributed products.
[0062] In the embodiment, the first dispensing assembly 3 and the second dispensing assembly 7 are synchronous or asynchronous dispensing.
[0063] Specifically, when dispensing synchronously, the first dispensing assembly 3 and the second dispensing assembly 7 can select the same glue, and the first dispensing assembly 3 and the second dispensing assembly 7 are lowered synchronously to dispense the products to be dispensed on the carrier.
[0064] Specifically, when dispensing asynchronously (for small products on small carriers, the interval between the two dispensing positions on the product is small, and synchronous dispensing is not possible), the first dispensing assembly 3 and the second dispensing assembly 7 can select different glues. The first dispensing assembly 3 dispenses, at this time the first dispensing assembly 3 moves downward along the Z axis, and the second dispensing assembly 7 moves upward along the Z axis. At this time, the first dispensing assembly 3 is below and the second dispensing assembly 7 is above, and a height difference is formed between the two. The first dispensing assembly 3 dispenses the first dispensing position of all products. When the first dispensing assembly 3 completes the dispensing operation, the second dispensing assembly 7 needs to be switched. At this time, the first dispensing assembly 3 moves upward along the Z axis, and the second dispensing assembly 7 moves downward along the Z axis. At this time, the second dispensing assembly 7 is below and the first dispensing assembly 3 is above, and a height difference is formed between the two. The second dispensing assembly 7 completes the dispensing operation and dispenses the second dispensing position of all products. Asynchronous dispensing is realized by switching the first dispensing assembly 3 and the second dispensing assembly 7. Due to the action of the independently adjustable three-axis fine adjustment assembly, the second dispensing assembly 7 can move independently relative to the first dispensing assembly 3.
[0065] The double-valve dispensing mechanism can realize different dispensing processes, not only dispensing the surface of the polygonal workpiece, but also dispensing the side wall and inclined surface of the polygonal workpiece. The stroke of the first dispensing assembly 3 and the second dispensing assembly 7 in the dispensing process is reduced, the dispensing efficiency is improved, and the cost is reduced.

In the present specification, the exemplary description of the above terms does not necessarily mean the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0067] With the above ideal embodiments according to the present application as the inspiration, through the above description, relevant personnel can certainly make various changes and modifications without deviating from the scope of the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined by the scope of the claims.
