[0035] Specifically, the dispensing device includes:

[0036] Bottom plate 1, bottom plate 1 is used to provide fixed support;

[0037] The rotating seat 2 is fixed on the bottom plate 1, and the rotating seat 2 carries the motor housing 5 to be dispensed. The rotating seat 2 is used to carry the motor housing 5 and drive the motor housing 5 to rotate;

[0038] The driving seat 3 is fixed on the base plate 1. The driving seat 3 is equipped with a glue injector 31 for containing glue liquid and a driving mechanism for driving the glue injector 31 to move. The bottom end of the glue injector 31 is equipped with a glue dispensing needle 311 for outputting glue liquid. The driving mechanism drives the glue injector 31 to move so as to make the glue dispensing needle 311 approach or move away from the part to be glued of the motor housing 5.

[0039] Combination Figure 3 As shown, in the present application, the driving seat 3 includes a support column 32 , a horizontal plate 33 , a fixing plate 34 , a limit block 35 , a slide rail 36 , a slider 37 , a driving cylinder 38 and a clamping assembly 39 .

[0040] Specifically, one end of the pillar 32 is fixed to the base plate 1, the cross plate 33 is fixed to the other end of the pillar 32, the fixed plate 34 is fixedly connected to the cross plate 33, the slide rail 36 is fixedly arranged on the fixed plate 34, the slider 37 is slidably arranged on the slide rail 36, the limit block 35 is located at one end of the slide rail 36 and fixed to the fixed plate 34, the driving cylinder 38 is located at the other end of the slide rail 36 and fixed to the fixed plate 34, the telescopic end of the driving cylinder 38 is fixedly connected to the slider 37 to drive the slider 37 to move, and the clamping assembly 39 is arranged on the slider 37, and the clamping assembly 39 is used to clamp the injector 31.

[0041] In this embodiment, in order to improve the stability of the support, the driving seat 3 includes two pillars 32 , and the two sides of the cross plate 33 are respectively fixedly connected to the pillars 32 .

[0042] Combination Figure 3 As shown, in this embodiment, the slide rail 36 is vertically disposed on the fixed plate 34 , and the slide rail 36 moves vertically along the slide rail 36 .

[0043] The glue injector 31 can be moved up and down in the vertical direction by the vertically arranged slide rail 36. Under the action of gravity, the glue liquid squeezed out by the glue dispensing needle 311 can flow better to the part of the motor housing 5 to be glued. At the same time, this arrangement can prevent the glue liquid remaining in the glue dispensing needle 311 from dripping onto other parts of the device when the glue injector 31 is away from the motor housing 5.

[0044] Combination Figure 3 As shown, in this embodiment, the clamping assembly 39 is composed of two hinged parts, and the opposite sides of the two parts are provided with notches that couple with the glue injector 31. After the two parts are assembled, the glue injector 31 can be clamped, which is convenient for driving the cylinder 38 to drive the glue injector 31 to move.

[0045] In the present application, a gas supply controller 4 for controlling gas output is fixedly provided on the base plate 1. The gas supply controller 4 supplies gas to the glue injector 31 through an air pipe 41. The glue injector 31 squeezes the glue liquid out of the glue dispensing needle 311 under the action of the gas supply pressure.

[0046] Combination Figure 1 As shown, in one embodiment, the glue injector 31 is in the form of a syringe, and an end plug 312 is provided at its opening, and the air pipe 41 is connected to the end plug 312, and the end plug 312 forms an airtight structure of the glue injector 31. The air supply controller 4 slowly supplies air to the glue injector 31, and the pressure of the gas inside the glue injector 31 increases, so that the glue liquid is squeezed out from the glue dispensing needle 311.

[0047] In other embodiments, a pneumatic piston may be provided inside the glue injector 31 , and the air supply controller 4 supplies air to the pneumatic piston through the air pipe 41 , and the pneumatic piston squeezes the glue liquid in the glue injector 31 out of the glue dispensing needle 311 under the action of the air supply pressure.

[0050] In the present application, the gas supply controller 4 can be connected to an external gas source, which is not shown in the drawings of the present application.

[0051] In the present application, the air source for driving the air cylinder 38 may also be supplied by the air supply controller 4, or may be connected to other external air sources.

[0052] Combined with Figure 4 and Figure 5 As shown, in the present application, the rotating seat 2 includes a first support 21, a second support 22, a motor 23 and a supporting block 24. The bottom end of the first support 21 is fixed to the base plate 1, the second support 22 is hinged to the first support 21 through a rotating shaft 25, the motor 23 is fixed to the second support 22, the rotating output end of the motor 23 is transmission-connected to the bottom end of the supporting block 24, and the top end of the supporting block 24 is used to place the motor housing 5.

[0053] Among them, combined Figure 4 As shown, in this embodiment, the first support 21 is provided with an arc groove 211, and the second support 22 is provided with a limiting rod 221. One end of the limiting rod 221 is movably accommodated in the arc groove 211, and the two ends of the arc groove 211 are used to limit the moving position of the limiting rod 221, thereby limiting the rotation range of the second support 22.

[0054] Specifically, in this embodiment, two arc-shaped grooves 211 are provided, and two limiting rods 221 are also provided to match the arc-shaped grooves 211 .

[0055] In order to facilitate rotation, the limiting rod 221 and the arc groove 211 are clearance-fitted.

[0056] In order to prevent the first support 21 and the second support 22 from loosening during the dispensing operation, the first support 21 and the second support 22 can be appropriately pressed against each other to provide friction damping to prevent excessive loosening.

[0057] Through the adjustable rotation of the first support 21 and the second support 22, the position of the bearing block 24 can be adjusted to facilitate the dispensing operation of motor housings of different sizes.

[0058] Combination Figure 5 As shown, the rotating output end of the motor 23 is transmission-connected to the bearing block 24 via a coupling 26 , a positioning block 27 is provided between the coupling 26 and the bearing block 24 , the positioning block 27 is fixedly connected to the second support 22 , and the positioning block 27 abuts against the bottom end of the bearing block 24 .

[0059] The coupling 26 is used to connect the rotation output end of the motor 23 and the bearing block 24, so that the rotation of the motor 23 can be smoothly transmitted to the bearing block 24, so that the bearing block 24 rotates. Specifically, the bearing block 24 can be provided with a rotating shaft, and the rotating shaft is connected to the coupling 26.

[0060] The positioning block 27 is used to position the bearing block 24 and can adjust the position of the bearing block 24 to facilitate the glue dispensing operation.

[0061] In order to avoid affecting the transmission, the positioning block 27 may be provided with a through hole so that the rotating shaft passes through the positioning block 27 .

[0062] Combination Figure 4 As shown, a plurality of positioning holes 241 are provided at the top of the bearing block 24 , and the positioning holes 241 are used for positioning with the motor housing 5 through positioning bolts.

[0063] Generally speaking, the ends of the micro motor housing are provided with small holes, which are used for ventilation and heat dissipation. When using the dispensing device of the present application, when the motor housing is placed on the bearing block 24, the bearing block 24 can be used to directly drive the motor housing placed above it to rotate synchronously; or, by aligning the small hole of the housing with the positioning hole 241 of the bearing block 24, and then inserting a pin, etc., when the bearing block 24 rotates, the motor housing can be rotated well synchronously.

The above description is only used to help understand the method of the present application and its core mechanism; at the same time, for general technical personnel in this field, according to the ideas of the present application, there will be changes in the specific embodiments and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
