[0006] A positioning plate, fixedly connected to the base portion, having at least one placement point for placing and positioning the workpiece;

[0007] The mounting plate is connected to the connecting part by sliding up and down; there is a dispensing head corresponding to each placement point;

[0008] A first cylinder drives the mounting plate to slide up and down;

[0009] The number of rotating downward pressing cylinders is equal to the number of placement points and is fixedly connected to the base portion; the end of the swing arm away from the piston rod is provided with a curing light.

[0010] Furthermore, the rotating downward-pressing cylinders are all located between the positioning plate and the connecting portion.

[0011] Furthermore, there are a plurality of positioning and placement plates, the placement points on each positioning and placement plate have different sizes, and each positioning and placement plate can be detachably fixedly connected to the base portion.

[0012] Furthermore, the dispensing head can be adjusted up and down to a fixed position on the mounting plate.

[0031] See also Figure 1 and Figure 2 A UV automatic dispensing and curing device includes an equipment frame 1, a positioning plate 2, a mounting plate 3, a first cylinder 4 and a rotating downward pressing cylinder 5.

[0032] The equipment rack 1 is L-shaped and includes a horizontal base portion 1a and a vertical connection portion 1b. The connection portion 1b can be fixedly connected to the rear side of the top surface of the base portion 1a by screws.

[0033] The positioning plate is fixedly connected to the base portion 1a, and specifically, the fixed connection between the two can also be completed by screws. The positioning plate has at least one placement point 2a for placing and positioning the workpiece (two placement points 2a are used as examples in the accompanying drawings).

[0034] Optionally, there are multiple positioning plates, that is, one UV automatic dispensing and curing device is equipped with multiple positioning plates, and the placement points 2a on each positioning plate have different sizes. Each positioning plate can be detachably fixedly connected to the base portion 1a.

[0035] In this way, different positioning and placing plates can be replaced to adapt to workpieces of different sizes, thereby increasing the scope of application and ensuring that the workpiece is positioned after being placed at the placement point 2a.

[0036] The mounting plate 3 is slidably connected to the connecting portion 1b, and the sliding connection between the two can be: an optical axis 6 can be arranged between the mounting plate 3 and the connecting portion. Specifically, the bottom end of the optical axis 6 is fixedly connected to the mounting plate 3, and a linear bearing 6a matching the optical axis 6 is fixedly connected to the connecting portion 1b.

[0037] See also Figure 4 and Figure 5Optionally, in combination with the above-mentioned setting that "the optical axis 6 may be provided between the mounting plate 3 and the connecting portion", a guide wheel 3a is further provided on the side of the mounting plate 3 close to the connecting portion 1b to abut against the connecting portion 1b. By adding the guide wheel 3a, the up and down sliding of the mounting plate 3 is made more stable, and the service life of the optical axis 6 is also increased.

[0038] See also Figure 1 and Figure 2 , the first cylinder 4 drives the mounting plate 3 to slide up and down.

[0039] The mounting plate 3 is provided with a dispensing head 3b at each placement point 2a, that is, when the mounting plate 3 is moved downward, all the dispensing heads 3b are matched one by one to the workpieces at all the placement points 2a, and then dispensing is performed. Accordingly, the dispensing head 3b cooperates with the dispensing system, which is a prior art and is not shown in the attached drawings; the dispensing system can be externally connected to the dispensing head 3b to squeeze out the glue in the dispensing head 3b.

[0040] Optionally, the dispensing head 3b can be adjusted up and down to a fixed position on the mounting plate 3. Specifically, a fixing clamp 3c can be fixedly connected to the mounting plate 3, and the dispensing head 3b is fixedly connected to the fixing clamp 3c by expansion. By loosening the fixing clamp 3c, the dispensing head 3b can be moved up and down.

[0041] Although the position of the dispensing head 3b during dispensing can be adjusted by adjusting the lower limit of the first cylinder 4, the cylinder limit adjustment is not accurate and convenient, and adjusting the lower limit of the first cylinder 4 also adjusts the position of all the dispensing heads 3b during dispensing. After setting it to "the dispensing head 3b can be adjusted up and down on the fixed position of the mounting plate 3", the position of the dispensing head 3b during dispensing can be adjusted by adjusting the fixed position of the dispensing head 3b on the mounting plate 3. On the one hand, it is more convenient for fine-tuning, and on the other hand, each dispensing head 3b can be adjusted independently.

[0042] See also Figure 3 Optionally, the dispensing head 3b can be adjusted left and right at the fixed position on the mounting plate 3. Combined with the above-mentioned setting that "the dispensing head 3b can be adjusted up and down at the fixed position on the mounting plate 3", the fixing clamp 3c can be adjusted left and right at the fixed position on the mounting plate 3. Specifically, the fixing clamp 3c can be provided with a waist-shaped through groove 3c1, and the mounting plate 3 is correspondingly provided with a threaded hole.

[0043] See also Figure 1 , Figure 2 and Figure 5 The number of the rotary pressing cylinders 5 is equal to the number of the placement points 2a, and they are fixedly connected to the base portion 1a. For each rotary pressing cylinder 5, a curing lamp 5b is provided at one end of the swing arm 5a away from the piston rod.

[0044] A PLC that controls the first cylinder 4 and the rotary pressing cylinder 5 may be disposed in the inner cavity of the base portion 1a.

[0045] In this way, during the process of glue dispensing by the glue dispensing head 3b, the swing arm 5a of the rotating downward pressure cylinder 5 is at the upper limit position, and the corresponding swing arm 5a is also completely outside the workpiece, without interfering with the glue dispensing head 3b. After the glue dispensing head 3b completes the glue dispensing, the first cylinder 4 drives all the glue dispensing heads 3b to move upward to leave space for the swing arm 5a, and the rotating downward pressure cylinder 5 moves to the lower limit position. Before the downward movement process is completed, the swing arm 5a completes the rotation first, so that the curing lamp 5b is above the workpiece, and the curing lamp 5b continues to move downward close to the workpiece to perform light curing on the glue at the glue dispensing position.

[0046] The positions of the rotary pressing cylinder 5 can all be on the front side of the positioning plate; there are two placement points 2a on the positioning plate, and the two rotary pressing cylinders 5 can also be respectively on the left and right sides of the positioning plate. It can be found that although the two positions of the rotary pressing cylinder 5 need to be designed on the base part 1a, they can be staggered with the mounting plate 3 more conveniently, so that the rotary pressing cylinder 5 will not interfere with the up and down sliding of the mounting plate 3.

[0047] Optionally, the rotary pressing cylinder 5 is located between the positioning plate and the connecting part 1b, that is, at the rear side of the positioning plate. It can be found that although this position setting of the rotary pressing cylinder 5 will overlap with the mounting plate 3, that is, it is necessary to pay attention to the setting of the lower limit of the mounting plate 3 to ensure that it does not hit the swing arm 5a of the rotary pressing cylinder 5, there is no need to design a position on the base part 1a, which can make the size of the base part 1a smaller and the entire UV automatic dispensing and curing equipment more compact.
