In this way, the position of the dispensing head 31 clamped by the first adjusting member 112 and the pressing member 12 in the third direction can be adjusted.

[0061] The pressing end 121 of the pressing member 12 and the adjusting body 1121 are respectively provided with a limiting groove 1123 on one side thereof close to each other, and the limiting groove 1123 of the pressing end 121 and the limiting groove 1123 of the adjusting body 1121 are arranged opposite to each other, and the two ends of the elastic member 14 respectively abut against the groove bottom of the limiting groove 1123 of the pressing end 121 and the groove bottom of the limiting groove 1123 of the adjusting body 1121. In this embodiment, the limiting groove 1123 is a circular groove, and the elastic member 14 is a spring or rubber, so that by providing the limiting groove 1123, the position of the elastic member 14 can be limited to prevent the position of the elastic member 14 from being offset.

[0062] Please also see Figure 4 The clamping groove 111 includes a first clamping wall 1111 and a second clamping wall 1112 connected to each other, and the first clamping wall 1111 and the second clamping wall 1112 both abut against the dispensing head 31. In this embodiment, the first clamping wall 1111 and the second clamping wall 1112 are both planes and the angle between them is an acute angle. In this way, by setting the first clamping wall 1111 and the second clamping wall 1112, and making the dispensing head 31 abut against the first clamping wall 1111 and the second clamping wall 1112 respectively, the first clamping wall 1111 and the second clamping wall 1112 can limit the position of the dispensing head 31 in the first direction and the second direction.

[0063] The rotating member 13 includes a penetration body 131 and a clamping portion 132. The penetration body 131 penetrates the groove wall of the holding member 12 and the limiting groove 1122A, and its two ends protrude from the two opposite groove walls of the limiting groove 1122A respectively. The clamping portion 132 is connected to one end of the penetration body 131.

In addition, the penetration body 131 and the clamping portion 132 can be an integrated structure, such as a bolt, and the setting of the locking member 15 can prevent the penetration body 131 from falling off from the groove wall of the limiting groove 1122A.

[0064] The positioning mechanism 10 further includes a toggle member 16, one end of which is connected to the holding end 121 and is disposed opposite to the adjustment assembly 11, and the other end of the toggle member 16 extends away from the holding end 121. In this embodiment, the toggle member 16 is a bolt, so that by arranging the toggle member 16 as a force-bearing extension arm of the holding member 12, it is convenient to apply a force to the toggle member 16, so that the toggle member 16 drives the holding member 12 to rotate.

[0065] The bracket 20 is fixed to one side of the adjustment component 11 of the positioning mechanism 10 .

[0066] The dispensing valve 30 is disposed on the bracket 20 . The dispensing valve 30 includes a dispensing head 31 . The dispensing head 31 is disposed in the clamping groove 111 and is elastically held by the holding end 121 of the holding member 12 .

[0067] The implementation process of the dispensing device 100 provided in the embodiment of the present application is as follows:

[0068] The toggle member 16 is pressed, and the toggle member 16 drives the abutting end 122 of the holding member 12 to move toward the adjusting body 1121 of the first adjusting member 112, and the elastic member 14 is compressed. The holding end 121 of the holding member 12 and the corresponding end of the adjusting body 1121 open in a scissor-shaped shape, and the dispensing head 31 of the dispensing valve 30 is installed in the clamping groove 111 of the adjusting body 1121. The end face of the dispensing head 31 is just at a preset distance from the bottom surface of the holding member 12, for example, 5mm. The toggle member 16 is released, and the holding end 121 of the holding member 12 is elastically pressed. The dispensing head 31 is held and restricted in the clamping groove 111 of the adjusting body 1121. Every time a dispensing valve 30 is replaced, the dispensing head 31 is always kept in this position to ensure the accuracy of the dispensing head 31 in the first and second directions. The accuracy in the third direction is limited by the exposed length of the dispensing head 31. The length of the dispensing valve 30 exposed from the dispensing head 31 can be kept consistent. Therefore, when replacing the dispensing valve 30, the accuracy of the first, second and third directions of the dispensing valve 30 does not need to be debugged again, and it can be directly put into production after replacement.

[0069] The above-mentioned positioning mechanism 10 and dispensing device 100 can fix the position of the dispensing head 31 by making the holding groove 111 of the adjustment component 11 accommodate part of the dispensing head 31, and making the holding end 121 of the holding member 12 elastically press the dispensing head 31 in the holding groove 111 under the action of the elastic member 14, thereby preventing the position of the dispensing head 31 from shifting after dispensing, and the positioning effect is better. In addition, since the operation of the external optical fiber positioning device to find the position of the dispensing head 31 after each dispensing is omitted, the dispensing efficiency can be improved.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
