Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing machines, in particular to a commutator glue dispensing machine. Background Art

[0002] The glue dispensing machine in the prior art can send the glue dispensing head to the predetermined position by means of three-axis linkage, but it can usually only dispense glue vertically downward, that is, it can only dispense glue on the upward side of the workpiece. However, in actual applications, it is necessary to dispense glue on the outer side of the copper hook of the motor commutator along the entire circumferential direction (the purpose is to increase the strength of the copper hook of the commutator to avoid deformation during high-speed operation), and the existing glue dispensing machine cannot meet this requirement. In view of the above technical problems, the present application proposes a new technical solution that can be used to dispense glue on the copper hook of the commutator along the circumferential direction. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide a commutator glue dispensing machine, aiming to solve the technical problem that the prior art glue dispensing machine cannot dispense glue on the commutator copper hook along the circumferential direction.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A commutator glue dispensing machine comprises a base, a frame, an X-axis drive device, a Y-axis drive device, a Z-axis drive device, and a glue dispensing head, wherein a glue dispensing head mounting seat is arranged on the Z-axis drive device, and the glue dispensing head is arranged on the glue dispensing head mounting seat; at least one station bracket is arranged on the base, and each station bracket mounting seat is respectively provided with a commutator mounting seat and a station motor for driving the commutator mounting seat to rotate.

[0006] Furthermore, in the commutator dispensing machine, the inlet end of the dispensing head is connected to a glue supply hose, and a pressure regulating valve and a solenoid valve are provided upstream of the glue supply hose.

[0007] Furthermore, in the commutator glue dispensing machine, a glue scraping tube is arranged on the glue dispensing head mounting seat, and a bevel cut is arranged at the bottom end of the glue scraping tube.

[0008] Furthermore, in the commutator dispensing machine, each station bracket includes an L-shaped plate, the horizontal arm of the L-shaped plate is connected to the base, and the vertical arm of the L-shaped plate is provided with a circular hole and an arc hole.

[0009] Furthermore, in the commutator dispensing machine, a total of 2 workstation brackets are arranged on the base.

[0010] Furthermore, in the commutator dispensing machine, the X-axis driving device includes a first shell, and a first driving motor and a first synchronous belt arranged in the first shell.

[0011] Furthermore, in the commutator dispensing machine, the Y-axis driving device includes a second shell, and a second driving motor and a second synchronous belt arranged in the second shell.

[0012] Furthermore, in the commutator dispensing machine, the Z-axis driving device includes a third housing, and a third driving motor and a third synchronous belt arranged in the third housing.

[0013] Beneficial effects: The utility model provides a commutator glue dispensing machine. Compared with the prior art, by setting up a station bracket, a commutator mounting seat, a station motor and other components, the commutator copper hook can be glued along the circumferential direction, thereby improving the strength of the commutator copper hook. Furthermore, by setting up two sets of station brackets, commutator mounting seats, and station motors, one station can dispense glue while another station can unload and load materials, thereby improving work efficiency.

[0019] The utility model provides a commutator glue dispensing machine. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] See also Figures 1 to 5 The utility model provides a commutator dispensing machine. The accompanying drawings are only used to explain the structural principle and are not proportional to the actual product. The accompanying drawings only depict structures related to the invention of this application, and some conventional structures are not specifically depicted. The terms "first", "second", "station motor", "drive motor" and the like described herein are merely different names for similar structures for the purpose of explanation, and are not intended to limit this application.

[0021] The commutator dispensing machine includes a base 11, a frame 12, an X-axis drive device 31, a Y-axis drive device 32, a Z-axis drive device 33, and a dispensing head 4. The Z-axis drive device is provided with a dispensing head mounting seat 49, and the dispensing head is arranged on the dispensing head mounting seat; at least one station bracket 5 is arranged on the base, and each station bracket mounting seat is respectively provided with a commutator mounting seat 61 and a station motor 62 for driving the commutator mounting seat to rotate.

[0022] It can be observed from the accompanying drawings that the main part of the commutator mounting seat includes a barrel 611 (not observable from the perspective of the accompanying drawings) for placing the commutator 9. A connecting seat 612 is provided at the end of the barrel for connecting with the workpiece support, and the workpiece motor 62 is provided on the connecting seat.

[0023] It should be noted that the selection of the X-axis and the Y-axis is not fixed as shown in the accompanying drawings. In actual applications, even if the names of the above-mentioned X-axis drive device and the Y-axis drive device are swapped (that is, the X-axis becomes the Y-axis, and the Y-axis becomes the X-axis), the essence of the technical solution does not change.

[0024] Furthermore, the inlet end of the glue dispensing head is connected with a glue supply hose 83, and a pressure regulating valve 82 and a solenoid valve 81 are arranged upstream of the glue supply hose. This arrangement facilitates the control of the glue output amount and pressure of the glue dispensing head.

[0025] Further, a scraping glue tube 41 is provided on the dispensing head mounting seat, and the bottom end of the scraping glue tube is provided with an oblique cut 410. By providing the scraping glue tube, the redundant glue on the steering gear copper hook can be scraped off, thereby controlling the thickness of the glue layer on the copper hook.

[0026] Furthermore, each station bracket includes an L-shaped plate, the horizontal arm 51 of the L-shaped plate is connected to the base, and the vertical arm 52 of the L-shaped plate is provided with a circular hole and an arc-shaped hole. This arrangement not only makes the station bracket structure simple, but also facilitates the adjustment of the inclination angle of the commutator mounting seat. That is, the circular hole provided in the vertical arm is used to pass the rotating shaft (not actually observed in the attached figure) and realize a rotatable connection with the commutator mounting seat. After adjusting the commutator mounting seat to a suitable angle, insert the locking bolt into the arc-shaped hole and screw it into the corresponding threaded hole on the commutator mounting seat (not actually observed in the attached figure).

[0027] Preferably, two workstation brackets are arranged on the base, which enables one workstation to dispense glue while another workstation is unloading and loading materials, thereby improving work efficiency.

[0028] The implementation methods of the above-mentioned X-axis drive device, Y-axis drive device, and Z-axis drive device can be diverse. The present application provides a simple setting, which is as follows: the X-axis drive device includes a first shell, and a first drive motor and a first synchronous belt arranged in the first shell; the Y-axis drive device includes a second shell, and a second drive motor and a second synchronous belt arranged in the second shell; the Z-axis drive device includes a third shell, and a third drive motor and a third synchronous belt arranged in the third shell.

[0029] It should be noted that, since the synchronous belt transmission method itself is a prior art, the accompanying drawings no longer specifically illustrate the structure of the synchronous belt and its corresponding synchronous pulley.

[0030] In actual use, the commutator is placed in the commutator mounting seat, and the X-axis drive device, Y-axis drive device, and Z-axis drive device move the dispensing head to the top of the commutator through three-axis linkage. The station motor drives the commutator to rotate, and the pressure regulating valve and solenoid valve control the glue output and pressure of the dispensing head. After the dispensing is completed, the station motor stops rotating and the dispensing head moves to another station. This reciprocating cycle.

[0031] For ease of understanding, Figure 5 The annular glue layer 91 formed after glue dispensing is schematically drawn in the figure, and the glue layer just wraps the outer side of the commutator copper hook, thereby improving the strength of the commutator copper hook.

[0032] It should be noted that, although the commutator 9 and the adhesive layer 91 are shown in the drawings, the commutator 9 and the adhesive layer 91 themselves are not within the protection scope of the present application.

[0033] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
