The gluing process of motor cores is currently one of the main ways to improve the performance of motor cores, and it puts forward higher requirements on the appropriate amount, uniformity and stability of glue supply.

[0003] The existing glue dispensing equipment is made of a cylinder and a piston assembly. The piston assembly moves in one direction under the drive of the drive assembly to absorb the glue, and then moves in the opposite direction under the drive of the drive assembly to discharge all the sucked glue. In order to ensure the amount of glue fed and thus the amount of glue discharged, the sealing between the cylinder and the piston assembly is very high. Once the sealing is poor, the glue discharge accuracy is affected. In the case of unstable glue discharge accuracy, it is difficult to meet the requirements of automotive electronic core gluing process. Summary of the invention

[0008] In order to realize multi-point dispensing at the same time, the quantitative dispensing device for the motor core also includes a shunt component, which is connected to the glue outlet and has at least two shunt outlets.

[0009] In order to facilitate the control of the opening and closing of the glue inlet and glue outlet, the quantitative glue dispensing device for the motor core also includes a glue inlet switch valve and a glue outlet switch valve. The glue inlet switch valve is arranged at the glue inlet or on a glue inlet pipe connected to the glue inlet, and the glue outlet switch valve is arranged at the glue outlet or on a glue outlet pipe connected to the glue outlet.

[0010] In order to further discharge the air in the glue, the glue inlet is located at the top of the cylinder body and is configured to be closed after a preset time delay after the glue filling is completed.

[0011] In order to facilitate accurate control of the stroke of the abutment assembly, the quantitative dispensing device for the motor core also includes:

[0012] A sensor assembly, used to detect the displacement of the abutment assembly;

[0013] The controller is connected to the sensor assembly and the power assembly respectively, and is used to control the operation of the power assembly according to the displacement detected by the sensor assembly.

DETAILED DESCRIPTION

[0023] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] like Figure 1 , 2 4, a quantitative dispensing device for a motor core, comprising:

[0026] The valve body assembly comprises a cylinder body 1 and a piston assembly 2. The cylinder body 1 has a glue inlet 11 and a glue outlet 12 which can be opened and closed respectively. The piston assembly 2 is slidably fitted in the cylinder body 1.

[0027] The glue discharging power mechanism includes a power component 3 and an abutment component 4. The power component 3 is connected to the abutment component 4 to drive the abutment component 4 to move. The abutment component 4 abuts against the piston component 2 during the movement toward the glue outlet 12 to push the piston component 2 to move.

[0028] The power assembly 3 may include, but is not limited to, a motor 31, a reducer 32, a screw 33 and a slider 34, wherein the screw 33 is rotatably supported on a fixed frame 9 of the fixed cylinder body 1, the output shaft of the motor 31 is connected to the input shaft of the reducer 32, the output shaft of the reducer 32 is connected to the screw 33, the slider 34 is slidably mounted on the fixed frame 9, is threadedly connected to the screw 33, and is also fixedly connected to the abutment assembly 4. The motor 31 and the reducer 32 are fixedly mounted on the fixed frame 9. The power assembly 3 may also be a pneumatic cylinder, an oil cylinder, an electric push rod, etc.

[0029] Specifically, during the working process, first open the glue inlet 11, close the glue outlet 12, and turn on the glue feeding air pressure of the feeding barrel to allow the glue in the feeding barrel to enter the cylinder body 1 through the glue inlet 11. After completing the quantitative glue supply, close the glue inlet 11, open the glue outlet 12, and drive the abutment assembly 4 through the power assembly 3 to push the piston assembly 2 toward the glue outlet 12 to complete the glue dispensing. By quantitatively supplying glue to the cylinder body 1, the glue discharge accuracy is guaranteed, thereby ensuring the quality of the motor core, and the sealing requirements between the cylinder body 1 and the piston assembly 2 are not high.

[0030] It should be noted that the glue inlet 11 and the glue outlet 12 can be closed by a valve or by blocking.

[0031] Embodiment 2

[0032] like Figure 3 As shown, based on the first embodiment, the quantitative glue dispensing device for the motor core further includes a shunt component 5 , which is connected to the glue outlet 12 and has at least two shunt ports 51 .

[0033] The motor core is formed by overlapping and gluing multiple punching sheets, and there are multiple gluing points between adjacent punching sheets. Therefore, in order to improve the dispensing efficiency of the quantitative dispensing device, the quantitative dispensing device needs to be able to achieve multi-point dispensing. At present, the existing dispensing equipment is realized by setting multiple glue outlets 12 on the cylinder body 1, which requires the configuration of multiple devices for controlling the opening and closing of the glue outlets 12, such as multiple glue outlet switch valves 7, plugging, etc., resulting in a bulky dispensing device and high cost. In this embodiment, a diverter component 5 is configured, and multi-point dispensing can be achieved by only setting one glue outlet 12 on the cylinder body 1, so that the entire quantitative dispensing device has a compact structure, a small size, and is easy to install and use. Figure 3 The diverter assembly 5 shown has four diverter ports 51 . It should be noted that the number of the diverter ports 51 is not limited to four, and may be two, three, five, six, etc., depending on the number of adhesive points.

[0034] Embodiment 3

[0035] On the basis of Example 1 or Example 2, Figure 1 As shown, the quantitative glue dispensing device for the motor core also includes a glue inlet switch valve 6 and a glue outlet switch valve 7. The glue inlet switch valve 6 is arranged at the glue inlet 11 or on the glue inlet pipe connected to the glue inlet 11, and the glue outlet switch valve 7 is arranged at the glue outlet 12 or on the glue outlet pipe connected to the glue outlet 12.

[0036] exist Figure 1 In the embodiment, the glue inlet switch valve 6 and the glue outlet switch valve 7 are respectively fixedly mounted on the fixing frame 9 , the glue inlet switch valve 6 is connected to the glue inlet pipe connected to the glue inlet port 11 , and the glue outlet switch valve 7 is connected to the glue outlet pipe connected to the glue outlet port 12 .

That is, after glue filling is completed, the glue inlet air pressure is first closed, and a preset time delay, generally 5s, 6s, etc., is made, and then the glue inlet 11 is closed. In this way, the air in the glue in the cylinder body 1 can be automatically discharged, and the firmness of the connection between adjacent punchings of the motor core can be ensured.

[0039] Embodiment 5

[0040] On the basis of the first embodiment, the second embodiment, the third embodiment, or the fourth embodiment, as Figure 4 As shown, the quantitative dispensing device for the motor core also includes:

[0041] A sensor assembly 8, used to detect the displacement of the abutment assembly 4;

[0042] The controller is connected to the sensor assembly 8 and the power assembly 3 respectively, and is used to control the operation of the power assembly 3 according to the displacement detected by the sensor assembly 8.

In this way, the moving stroke of the abutment assembly 4 can be limited.

[0044] Embodiment 6
