Description

Technical Field

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

[0002] A certain number of magnets need to be regularly installed on the motor rotor. The magnets are usually fixed by the slots on the inner wall of the rotor housing.

[0028] Ginseng Figures 1 to 8 As shown, a dispensing machine includes a horizontally arranged workbench 1, a dispensing mechanism 2 arranged on the workbench 1, and a placement fixture 3 for placing a motor rotor, the dispensing mechanism 2 includes a dispensing head 21 and a displacement mechanism 22 driven and connected to the dispensing head 21, the placement fixture 3 includes a support frame 31 and a placement seat 32 rotatably arranged on the support frame 31, a placement groove is arranged at the top center of the placement seat 32, the bottom of the placement seat 32 is connected to a rotating motor 34 through a rotating shaft 33, the rotating motor 34 is arranged on the workbench 1 through a motor seat 35, and its output shaft is driven and connected to the rotating shaft 33 through a coupling 36, and the support frame 31 is arranged at the top of the motor seat 35.

[0029] In this technical solution, the workbench is horizontally arranged through conventional structures such as profiles and table foot bolts, and a number of conventional mounting holes, avoidance holes, etc. are arranged therein. The displacement mechanism drives the dispensing head to move in the horizontal and vertical directions. The motor seat and the support frame are both groove-shaped structures with the opening facing downward (towards the side of the workbench), which are formed by splicing or processing of plates. The rotating motor is vertically arranged on the workbench through the motor seat, and avoidance holes corresponding to the rotating motor are processed in the workbench. The output shaft of the rotating motor passes through the motor seat and is connected to the rotating shaft through a coupling. The rotating shaft is a multi-section shaft structure. The top of the placement seat is fixed to the top surface of the rotating shaft by screws, etc., so that the placement seat and the motor rotor are driven to rotate together by the rotating motor. The dispensing head does not need to rotate to complete the dispensing work on the circumferential surface of the motor rotor. The bottom surface of the placement groove protrudes with positioning pins corresponding to the holes of the motor rotor, thereby improving the placement accuracy of the motor rotor and ensuring that it rotates synchronously with the placement seat. The dispensing machine has a compact structure, and the placement seat is rotatably arranged, which is convenient for completing arc or ring-shaped dispensing work. The dispensing mechanism does not need to rotate, saving space.

[0030] For example, see Figures 1 to 5 As shown, the rotating shaft 33 is rotatably disposed on the supporting frame 31 through a bearing seat 37 .

[0031] In this technical solution, the structure of the bearing seat is the existing technology, and is fixed to the top of the support frame by screws, etc., and the rotating shaft is set on the bearing seat by a retaining spring, etc. to ensure its smooth rotation.

[0032] For example, see Figures 1 to 4 As shown, a dirt collecting tray 38 is provided at the top end of the bearing seat 37 .

[0033] In this technical solution, the dirt collecting tray is fixed to the top of the bearing seat by screws, and a through hole is provided in the center thereof so as not to interfere with the rotation of the rotating shaft and the placement seat. A dirt collecting groove is recessed on the top surface of the dirt collecting tray to collect dripping glue, etc., for convenient centralized treatment.

[0034] For example, see Figures 1 to 5 As shown, a sensing block 39 is disposed on the outer wall of the placement seat 32 , and a sensor 310 corresponding to the sensing block 39 is disposed on the side of the support frame 31 .

[0035] In this technical solution, the sensor is fixed to the side of the support frame through the sensor bracket, the sensor block is fixed to the side of the placement seat through screws and rotates with the placement seat, and the sensor block cooperates with the sensor to confirm the starting position of the rotation of the placement seat.

[0036] For example, see Figure 1 , Figure 2 and Figure 6 As shown, the displacement mechanism 22 includes a first electric cylinder 221 arranged on the workbench 1, a second electric cylinder 222 arranged on the slide of the first electric cylinder 221 and a third electric cylinder 223 arranged on the slide of the second electric cylinder 222. The dispensing head 21 is arranged on the slide of the third electric cylinder 223. The first electric cylinder 221 and the second electric cylinder 222 drive the dispensing head 21 to move horizontally, and the driving directions of the first electric cylinder 221 and the second electric cylinder 222 are different. The third electric cylinder 223 drives the dispensing head 21 to move vertically.

[0037] In this technical solution, the first electric cylinder, the second electric cylinder and the third electric cylinder all use existing servo electric cylinders, and cables and the like are centrally arranged through conventional tank chains, etc., driving the dispensing head to move three-dimensionally in the X-axis direction formed by the first electric cylinder, the Y-axis direction formed by the second electric cylinder, and the Z-axis direction formed by the third electric cylinder.

[0038] For example, see Figure 1 , Figure 2 as well as Figure 6 and Figure 7 As shown, the dispensing head 21 includes a connecting plate 211 arranged on the slide of the third electric cylinder 223, a dispensing valve 212 rotatably arranged on the connecting plate 211, and a hose 213 connected to the dispensing valve 212. The hose 213 is connected to the connecting plate 211 through a mounting frame 214, and is rotatably connected to the dispensing valve 212 through a joint.

[0039] In this technical solution, the connecting plate is fixed to the slide of the third electric cylinder by screws, etc., and a countersunk hole is provided at one end thereof close to the dispensing valve, and the plate is connected to the side of the dispensing valve by screws. A bushing or bearing is provided between the dispensing valve and the connecting plate, and the screw is rotated through the bushing. When the screw is loosened, the installation angle of the dispensing valve can be adjusted. The dispensing valve can use the structure recorded in the prior art. The hose and the joint are both conventional structures. The mounting frame improves the stability of the hose fixation, and a hose mounting hole is provided therein. An insert is provided on the side of the mounting hole. When replacing the hose, the connection between the hose and the joint is disassembled, and the top screw abutting against the side of the insert is loosened to remove the hose. When installing the hose, the hose is inserted into the hose mounting hole and connected to the joint, the insert is pushed to abut against the outer wall of the hose, and the top screw is tightened.

[0040] For example, see Figure 1 , Figure 2 and Figure 6 As shown, the workbench 1 also includes a dirt collecting cup 4 arranged on the workbench 1.

[0041] In this technical solution, the dirt collecting cup is set on the workbench through a support rod and a placement ring. The support rod is vertically fixed to the top surface of the workbench through a conventional guide shaft seat. The mounting ring is fixed to the top of the support rod by screws. The dirt collecting cup is placed in the mounting ring. The dirt collecting cup is set at the stop position or origin position of the dispensing head to prevent glue from dripping on the dispensing head when it is not in use or when the motor rotor is loading and unloading.

[0042] For example, see Figure 1 , Figure 2 and Figure 8 As shown, it also includes a visual detection mechanism 5, which includes a base 51 fixed to the workbench 1 and a CCD detection device 52 set on the base through an adjustment device.

[0043] In this technical solution, the structure and distance of the CCD detection device are all existing technologies and will not be elaborated one by one. The CCD detection device can detect the corresponding dispensing status during the dispensing process and can find problems in time. The dispensing head does not need to rotate around the motor rotor during the dispensing process. There is enough space to set up a visual inspection mechanism, and the dispensing and inspection processes can be completed in a short time, thereby improving work efficiency.

[0044] For example, see Figure 1 , Figure 2 and Figure 8 As shown, the adjusting device includes a bottom plate 53 fixed to the top of the base and a slider 54 slidably arranged on the top surface of the bottom plate 53, the CCD detection device 52 is fixed to the slider 54, the top surface of the bottom plate 53 is provided with a slide groove corresponding to the slider 54, a plurality of threaded holes are arranged in the slide groove, waist-shaped holes are respectively arranged on both sides of the slider, and are disassembled and assembled to the corresponding threaded holes by bolts (not shown).

[0045] In this technical solution, when the distance between the CCD detection device and the motor rotor exceeds the focusing range of the CCD detection device, the distance between the CCD detection device and the motor rotor is adjusted by adjusting the position of the slider in the base plate, thereby improving the clarity of the image acquired by the CCD detection device and thus improving the accuracy of detection.

[0046] For example, see Figure 8 As shown, a magnifying glass 6 is arranged between the CCD detection device 52 and the placement seat 32 .

[0047] In this technical solution, the magnifying glass is a conventional lighted magnifying glass, and is connected to the base plate through a connecting frame, so as to improve the clarity of the image obtained by the CCD detection device, thereby improving the accuracy of the detection.

[0048] In summary, the glue dispensing machine has a compact structure, and the rotatably arranged placement seat facilitates arc or ring-shaped glue dispensing work, and the glue dispensing mechanism does not need to rotate, thus saving space.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0050] The above is only a specific implementation of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
