Description

Technical Field

[0001] The present invention relates to the technology of motor production coating, and in particular to an all-in-one automatic gluing and oiling machine for motor cover and shell and a gluing and oiling method, which is mainly but not limited to the gluing and oiling process in the production of small EV motors. Background Art

[0002] During the motor manufacturing process, glue and oil need to be applied in many places. For example, the inner wall of the assembly cavity (or hole) inside the motor housing and cover needs to be oiled to reduce the wear of the product mating surface and prevent its surface corrosion. In addition, a circle of glue needs to be applied to the periphery of the cover.

[0003] In the prior art, automatic gluing and automatic oiling are generally adopted, wherein the automatic gluing is performed by a gluing robot provided on the gluing equipment with a glue gun. The gluing robot generally includes a mounting frame, on which a first robot arm with a rotation axis extending in the up-down direction is provided, a second robot arm with a rotation axis perpendicular to the rotation axis of the first robot arm is hinged on the first robot arm, a third robot arm is hinged on the second robot arm, and a gluing gun is installed on the third robot arm, so that the gluing robot can meet the multi-directional automatic gluing. After the automatic gluing is completed, the product is transferred to the next station for gluing CCD detection, and the gluing position is detected by the gluing CCD detection unit. Similarly, the process requiring oiling is performed by an oiling robot provided on the oiling equipment with an oil gun. After the automatic oiling is completed, the product is transferred to the next station for gluing CCD detection, and the oiling position is detected by the oiling CCD detection unit. Therefore, the number of devices is large, the space occupied is large, and the control of the device cost is also limited.

[0004] In addition, the existing automatic oiling is operated by an oiling manipulator provided on the oiling equipment with an oil gun. The oiling manipulator generally includes a mounting frame, on which a first mechanical arm with a rotation axis extending in the up-down direction is provided, a second mechanical arm with a hinge axis perpendicular to the rotation axis of the first mechanical arm is hinged on the first mechanical arm, a third mechanical arm is hinged on the second mechanical arm, and an oiling gun is installed on the third mechanical arm, so that the oiling manipulator can meet the multi-directional automatic oiling. This method of using an oiling manipulator is generally not suitable for the strict requirements of inner circle oiling. It is difficult to achieve a regular circle oiling effect due to the hinge structure. If the inner circle oiling needs to be completed, the oiling gun can only be changed to a horizontally rotatable structure, that is, the oiling gun is connected to the manipulator through a horizontal rotating part. However, for holes with different inner diameters, it is necessary to replace oiling guns of different sizes, or change the size of the horizontal rotating part. In this way, in the production process of the motor, holes with different inner diameters need to use multiple oiling devices. On the one hand, the device cost is increased, and on the other hand, multiple switching of different oiling devices will inevitably have a negative impact on production efficiency.

[0005] There is also a device for oiling the inner hole. In the non-working state, the oiling motor, oiling shaft synchronous wheel, oiling mechanism synchronous belt, oiling feed proximity switch, oiling motor synchronous wheel, oiling mechanism lifting linear guide column, oiling rotating spindle, and bearing fixing sleeve connected to the oiling mechanism fixed plate are controlled by the oiling reset proximity switch to control the oiling mechanism lifting cylinder to be at the lowest point. When the product is placed in the product positioning block, it will trigger the photoelectric material detector to issue an instruction, so that the oiling mechanism lifting cylinder works upward and drives the oiling mechanism to move upward. The stroke adjustment rod will touch the oiling feed proximity switch, and the oiling feed proximity switch will issue an instruction to make the oiling motor and the workpiece rotating motor rotate; at the same time, the high-pressure oil injection pump will inject the lubricating oil into the oiling rotating spindle through the control of the flow regulating valve. Under the action of centrifugal force, the lubricating oil will be thrown very evenly on the inner hole surface of the product. After the application is completed, the oiling mechanism lifting cylinder returns to its original position and touches the oiling reset proximity switch to cut off all power signals, and the entire oiling work is completed. Theoretically, this inner hole oiling method can be applied to inner hole surfaces with different inner diameters because it throws the lubricating oil onto the inner hole surface of the product through the action of centrifugal force. However, inner hole surfaces with different inner diameters also mean that they are at different distances from the oiling rotating spindle, resulting in different forces and spreading areas when the lubricating oil is thrown onto the inner hole surface of the product. Therefore, a device that can meet the requirements of oiling inner hole surfaces with one inner diameter is still difficult to meet the requirements of oiling inner hole surfaces with another different inner diameter with higher oiling requirements (such as control of the oiling area, control of the oiling amount, etc.). Moreover, the overall structure of this oiling device is relatively complex, and the product needs to be positioned at the upper position. If it is used to oil the inner wall of the assembly cavity (or concave hole) inside the motor housing and cover, the motor housing and cover can only be inverted (i.e., the opening faces downward), which makes it difficult to position the motor housing and cover. After oiling, the oil will flow downward, resulting in less than ideal controllability of the oiling area.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0007] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide an all-in-one machine and a method for automatic gluing and oiling of motor covers and shells, which realizes automatic gluing and oiling on the all-in-one machine, has a small number of devices and occupies a small space. At the same time, it is beneficial to improve the efficiency of gluing and oiling. The cover and the shell are located on the same slide, which is also convenient for the subsequent assembly of the cover and the shell on the automated production line.

[0008] To achieve the above purpose, the present invention adopts the following technical solutions:

[0009] An automatic gluing and oiling machine for motor cover and housing, comprising a frame and a gluing mechanism and an oiling mechanism arranged on the frame;

[0010] The front side of the frame is provided with slide rails extending left and right, and a slide table is provided along the slide rails for left and right transportation, and the slide table has a motor cover placement position and a motor casing placement position; a multifunctional manipulator is provided on the rear side of the frame corresponding to the slide rails, and placement racks are respectively provided on the left and right sides of the frame corresponding to the multifunctional manipulator, and the gluing mechanism and the oiling mechanism can be positioned on the corresponding left and right placement racks respectively; the gluing mechanism and the oiling mechanism both have an extraction adapter, and the multifunctional manipulator is provided with an extraction head for detachably connecting the gluing mechanism and the oiling mechanism, and the extraction head can be selectively adsorbed and connected to or detached from any extraction adapter.

[0011] As a preferred solution, the extraction head is provided with an adapter, and the adapter is connected to a CCD detection head.

[0012] As a preferred solution, the CCD detection head is connected to a connecting piece, and an illumination lamp and a blue UV lamp are arranged below the CCD detection head via the connecting piece.

[0013] As a preferred embodiment, the multifunctional manipulator includes a base, a rotating base, a first articulated arm and a second articulated arm which are connected in sequence; the rotating base can be automatically rotated horizontally relative to the base; one end of the first articulated arm is hinged to the upper end of the rotating base so as to be automatically rotatable relative to the upper end of the rotating base; one end of the second articulated arm is hinged to the other end of the first articulated arm so as to be automatically rotatable relative to the other end of the first articulated arm; the upper end of the extraction head can be automatically rotatably connected to the other end of the second articulated arm.

[0014] As a preferred solution, the oiling mechanism includes an oiling nozzle, an oiling spindle, an oiling nozzle mounting seat and an elastic abutment wheel assembly; the oiling nozzle mounting seat is sleeved on the lower end of the oiling spindle and can rotate around the oiling spindle, and an oiling nozzle mounting hole is arranged on the circumference of the oiling nozzle mounting seat; the oiling nozzle is arranged in the oiling nozzle mounting hole and extends outwardly along the radial direction of the oiling spindle; the elastic abutment wheel assembly is provided with two groups, which are respectively located on both sides of the oiling nozzle; the elastic abutment wheel assembly It includes an abutment wheel, an abutment wheel frame and an elastic element; the circumferential surface of the abutment wheel is arranged around the upper and lower axes, the inner end of the abutment wheel frame is hinged to the oiling nozzle mounting seat through a first vertical axis, and the abutment wheel is hinged to the outer end of the abutment wheel frame through a second vertical axis, one end of the elastic element acts on the oiling nozzle mounting seat, and the other end of the elastic element acts on the abutment wheel frame so that the abutment wheel has an external resistance force toward the inner wall surface to be oiled; the multifunctional manipulator can move along a set circle with the oiling spindle. By setting the oiling spindle, the oiling nozzle mounting seat and the elastic abutment wheel assembly, the manipulator can move the oiling spindle along the set circumference to meet the oiling needs of hole surfaces with different inner diameters. For hole surfaces with larger inner diameters, the manipulator can move along a larger set circumference. Conversely, for hole surfaces with smaller inner diameters, the manipulator can move along a smaller set circumference. In this way, the distance between the oiling nozzle and the hole surface to be oiled can be flexibly adjusted, and the oiling is well controllable. Moreover, the oiling nozzle mounting seat is sleeved on the lower end of the oiling spindle and can rotate around the oiling spindle. When the oiling spindle moves along the set circumference, with the cooperation of the elastic abutment wheel assembly, the oiling nozzle rotates relative to the oiling spindle together with the oiling nozzle mounting seat, so that the oiling nozzle sprays oil radially toward the inner hole surface, the coating effect is good, and the oiling area can form a precise circumference. Therefore, the depth of the oiling area, the oiling area, etc. can be precisely controlled. In addition, the oiling mechanism has a simple structure, and a conventional robot can be used as the manipulator. The oiled product can be placed and positioned normally, and is also suitable for automatic transfer and transportation of conventional automatic production lines.

[0051] A method for automatic gluing and oiling of a motor cover and a housing, which is based on the aforementioned motor cover and housing automatic gluing and oiling integrated machine; when performing automatic gluing and oiling, the method comprises the following steps:

[0052] Step 1, the slide 205 loaded with the motor cover 208 and the motor housing 209 is located on the slide rail 204 on the front side of the frame 201; it should be noted that the structure of the motor cover 208 and the motor housing 209 is not limited, and the motor cover 208 and the motor housing 209 in the accompanying drawings are only for illustration, not the actual structure of the specific motor cover 208 and the motor housing 209. The equipment and the method for applying glue and oil of the present invention are suitable for motor covers 208 and motor housings 209 of different structures, and are mainly used to apply oil to the inner annular surface of the inner hole on the motor cover 208 and the motor housing 209, and to apply glue to the peripheral part of the motor cover 208.

[0053] Step 2, the multifunctional manipulator 104 extracts the oiling mechanism 203 from the placement rack 6 on the right side, and respectively applies oil to the inner annular surface of the inner hole of the motor cover 208 and the motor housing 209; here, the multifunctional manipulator 104 extends the oiling spindle into the hole to be oiled and moves along the set circumference to complete the oiling along the inner circumference of the hole to be oiled, and the set circumference is located between the center of the hole to be oiled and the inner circumference of the hole to be oiled, and then the multifunctional manipulator withdraws the oiling spindle upward from the hole to be oiled. Preferably, the multifunctional manipulator first extends the oiling spindle into the center of the hole to be oiled, then radially deviates outward to the set circumference, then moves along the set circumference for one circle to complete the oiling along the inner wall of the hole to be oiled, then radially deviates inward to the center of the hole to be oiled, and finally withdraws the hole to be oiled upward at the center of the circle.

[0054] Step 3, the multifunctional manipulator 104 puts the oiling mechanism 203 back onto the placement rack on the right side;

[0056] Step 5, the multifunctional robot 104 extracts the gluing mechanism 202 from the placement rack on the left, and applies glue to the peripheral area of ​​the motor cover 208 in a circle; in this embodiment, the gluing area is the top surface of the motor cover 208 near the peripheral area, so the gluing head of the gluing mechanism 202 can adopt a downward glue discharge method when applying glue.

[0057] Step 6, the multifunctional manipulator 104 puts the glue coating mechanism 202 back onto the placement rack on the left side;

[0058] In step 7, the multifunctional robot 104 performs CCD detection on the glue-coated area; preferably, after step 7 and before step 8, the multifunctional robot 104 performs UV light curing on the glue-coated area.

[0059] Step 8: The slide 205 moves from the slide rail 204 on the front side of the rack 201 to the next workstation.

[0060] Next, if Figures 4 to 7 As shown in the figure, the structure and working principle of the oiling mechanism are introduced in detail, which can meet the oiling needs of the inner hole surfaces of motor covers and motor housings with different inner diameters:

[0061] The oiling mechanism includes an oiling nozzle 101, an oiling spindle 7, an oiling nozzle mounting seat 102, and an elastic abutment wheel assembly 103. Furthermore, the oiling spindle 7 is connected to a manipulator 104, and the manipulator 104 can move the oiling spindle 7 along a set circumference.

[0062] The oiling spindle 7 has an extraction adapter 72, a placement rack 6 is provided for the oiling spindle 7, the oiling spindle 7 has a placement seat 71, and the extraction adapter 72 is provided on the top of the placement seat 71. An oil storage tank can be provided inside the oiling spindle 7 for oil supply, or oil can be supplied through an external oil pipe.

[0063] The oiling nozzle mounting seat 102 is sleeved on the lower end of the oiling spindle 7 and can rotate around the oiling spindle 7. The circumferential side of the oiling nozzle mounting seat 102 is provided with an oiling nozzle mounting hole 117; the oiling nozzle 101 is arranged in the oiling nozzle mounting hole 117 and extends outward along the radial direction of the oiling spindle 7; the lower end of the oiling spindle 7 is internally provided with a first oil groove, and the external oil pipe is connected to the input end of the first oil groove. The circumferential side of the lower end of the oiling spindle 7 is provided with a plurality of oil outlets arranged along the circumferential spacing. The hole 701 serves as the output end of the first oil groove, and the sleeve hole 1021 of the oiling nozzle mounting seat 102 and the lower end circumference of the oiling spindle 7 form a second oil groove 702, which is an annular groove around the lower end circumference of the oiling spindle 7. The plurality of oil outlet holes penetrate the inner side of the annular groove, and the inner end of the oiling nozzle 101 penetrates the outer side of the annular groove, so that the oiling nozzle 101 keeps the oil supply connected when rotating with the oiling nozzle mounting seat 102 relative to the oiling spindle 7. The structure is ingenious and compact, and the annular groove is formed by the oiling nozzle mounting seat 102 and the oiling spindle 7 to ensure that the oil supply demand of the oiling nozzle 101 can be met when rotating to any position for oiling.

[0064] The elastic abutment wheel assembly 103 is provided with two groups, which are symmetrically located on both sides of the oiling nozzle 101; the elastic abutment wheel assembly 103 includes an abutment wheel 105, an abutment wheel frame 106 and an elastic element 107; the wheel circumference of the abutment wheel 105 is arranged around the upper and lower axes, and the height of the wheel circumference of the abutment wheel 105 is lower than the height of the oiling nozzle 101, so that the abutment will not affect the oiling area, especially the abutment wheel 105 located on the rear side of the oiling nozzle 101 in the oiling direction. The inner end of the abutment wheel frame 106 is hinged to the oiling nozzle mounting seat 102 through the first vertical axis 108, and the abutment wheel 105 is hinged to the outer end of the abutment wheel frame 106 through the second vertical axis 109. One end of the elastic element 107 acts on the oiling nozzle mounting seat 102, and the other end of the elastic element 107 acts on the abutment wheel frame 106 so that the abutment wheel 105 has an external resistance force toward the inner wall surface to be oiled. Here, the other end of the elastic element 107 acts on the abutment wheel frame 106 corresponding to the position between the first vertical axis 108 and the second vertical axis 109 to drive the abutment wheel frame 106 to rotate relative to the first vertical axis 108 toward the side where the oiling nozzle 101 is located, thereby maintaining the elastic abutment force. In this embodiment, the elastic element 107 is a pressure spring, one end of which extends into the spring mounting groove 110 of the oil nozzle mounting seat 102, and a groove 111 is provided on the abutting wheel frame 106 corresponding to the position between the first vertical axis 108 and the second vertical axis 109, and the other end of the elastic element 107 abuts in the groove 111; it has a simple structure and is easy to produce and manufacture, and the installation and positioning of the elastic element 107 is simple and convenient. Furthermore, in this embodiment, the outer end screw of the oiling nozzle mounting seat 102 is assembled with an end plate 116, and an avoidance hole 118 is provided on the end plate 116, which is arranged opposite to the oiling nozzle mounting hole 117, so that the outer end of the oiling nozzle 101 can extend out. The periphery of the end plate 116 is locked into the outer end screw hole of the oiling nozzle mounting seat 102 by a plurality of screws, and the outer end of the mounting cavity 119 of the oiling nozzle mounting seat 102 is blocked by the end plate 116 to limit the angle range of the abutment wheel frame 106 to the side where the oiling nozzle 101 is located. At the same time, the structure of the oiling nozzle mounting seat 102 is simpler and easier to produce by making and assembling the end plate 116 separately.

[0065] When applying oil, the manipulator 104 first extends the oiling spindle 7 into the circle center of the hole 112 to be oiled, then radially deflects outward to the set circumference 113, then moves along the set circumference 113 for one circle to complete oiling along the inner wall of the hole 112 to be oiled, then radially deflects inward to the circle center of the hole 112 to be oiled, and finally exits the hole 112 to be oiled. Taking the center of the circle as the base point, the oiling spindle 7 can be deflected by a corresponding distance to different set circumferences according to the oiling requirements of the inner hole surface with different inner diameters. The algorithm of the control system is relatively simple, which is conducive to reducing the failure rate of the control system, and the cost of the control system is also low. The oiling spindle 7 is provided with a positioning cylinder, and here, a needle cylinder 703 is used as the positioning cylinder. The end of the oiling nozzle mounting seat 102 away from the oiling nozzle 101 is provided with a positioning groove 115. In the initial state, the needle cylinder 703 is directly opposite to the upper part of the positioning groove 115. When the oiling nozzle 101 rotates 360 degrees relative to the oiling spindle 7 to complete one circle of oiling of the inner annular surface, the positioning groove 115 is directly opposite to the lower part of the needle cylinder 703 again. And the needle cylinder 703 extends downward into the positioning groove 115 to lock the current position of the oiling nozzle 101, ensuring that the position and angle of the next oiling are the same. In the next oiling operation, in the initial state before the oiling starts, the needle cylinder 703 first retracts upward away from the positioning groove 115 to release the lock on the oiling nozzle 101.

[0066] like Figures 8 to 10 As shown, the multifunctional manipulator 104 includes a manipulator body, and the manipulator body includes a base 1, a rotating base 2, a first articulated arm 3 and a second articulated arm 4 which are connected in sequence; the rotating base 2 can be automatically horizontally rotated relative to the base 1; one end of the first articulated arm 3 is hinged to the upper end of the rotating base 2, so that it can be automatically rotated relative to the upper end of the rotating base 2; one end of the second articulated arm 4 is hinged to the other end of the first articulated arm 3, so that it can be automatically rotated relative to the other end of the first articulated arm 3; the other end of the second articulated arm 4 on the manipulator body is provided with an extraction head 5 for detachably connecting to the oiling spindle 7, the upper end of the extraction head 5 can be automatically rotatably connected to the other end of the second articulated arm 4, and the extraction head 5 has an adapter seat 51, and the adapter seat 51 is connected to a CCD detection head 52. The connection relationship among the base 1, the rotating base 2, the first articulated arm 3, the second articulated arm 4, and the extraction head 5 and the technology of the corresponding automatic control action can be realized by relying on the current mature robot technology, and will not be elaborated here.

[0067] The lower end surface of the extraction head 5 has a positioning area and an adsorption area, and the extraction operation is simple and controllable. The adsorption area of ​​the extraction head is a vacuum adsorption area or a magnetic adsorption area. The positioning area of ​​the extraction head has a positioning hole. In this embodiment, the extraction head 5 includes an upper articulated seat 53 and a lower suction seat 54. The upper end of the upper articulated seat 53 can be automatically rotatably connected to the other end of the second articulated arm 4, and the lower end of the upper articulated seat 53 is installed on the upper end of the adapter seat 51. The adapter seat 51 has a connecting arm 511 extending toward the side, and the CCD detection head 52 is installed on the connecting arm 511; the upper end of the lower suction seat 54 is installed on the lower end of the adapter seat 51, and the positioning holes and the adsorption holes are arranged on the lower suction seat 54. The structural design is ingenious and reasonable. The adapter seat 51 is equivalent to acting as a part of the extraction head 5. Only the extension arm needs to be used for the installation of the CCD detection head 52, which saves the design materials of the extraction head 5, and also takes into account the consideration that the adapter seat 51 needs to flexibly design the required structure.

[0068] The CCD detection head 52 is connected to a connector 55, and an illuminating lamp and a blue UV lamp are arranged below the CCD detection head 52 through the connector 55. The illuminating lamp and the blue UV lamp are integrated, and the illuminating lamp facilitates CCD detection. When applying oil, white grease is applied, and the white grease is difficult to distinguish from the metal color of the motor housing, and cannot be detected by ordinary white light. Therefore, it is necessary to use the blue UV light emitted by the blue UV lamp to cooperate with CCD to detect whether the oiling is defective such as oil shortage or insufficient oil. The lower end of the connector 55 is connected to an annular lamp holder 56, and the illuminating lamp and the blue UV lamp are respectively arranged on the annular lamp holder 56 and can emit light toward the bottom of the annular lamp holder 56. In this way, the detection area of ​​the CCD detection head 52 is correspondingly located above the inner ring area of ​​the annular lamp holder 56. Its structural design is ingenious and reasonable, and the structural layout is compact. The detection area of ​​the CCD detection head 52 can be detected through the inner ring area of ​​the annular lamp holder 56. Preferably, the lighting lamp and the blue UV lamp are respectively arranged along the annular bottom spacing of the annular lamp holder 56. In this way, the lighting lamp and the blue UV lamp can be arranged along the annular lamp holder 56 to meet the lighting area requirements, and are particularly suitable for the detection of the annular oiling area formed by oiling the inner hole peripheral wall of the cover and the shell. At the same time, it is also suitable for the detection and light curing of the annular glue-coating area formed after the peripheral edge of the cover is glued.

[0069] Next, please refer to Figures 11 to 16As shown, several working states in the oiling process are selected. When the oiling operation is performed, first, the product with the hole to be oiled (such as the motor housing or / and the cover) is placed and positioned, and the opening of the inner hole is set upward; then the multifunctional manipulator leads the oiling spindle 7 into the hole to be oiled and moves along the set circumference 113 to complete a circle of oiling along the inner circumference of the hole to be oiled 112, and the set circumference 113 is located between the center of the hole to be oiled 112 and the inner circumference of the hole to be oiled 112; finally, the multifunctional manipulator leads the oiling spindle 7 out of the hole to be oiled. When the oiling spindle 7 moves along the set circumference 113, with the cooperation of the elastic abutment wheel assembly 103, the oiling nozzle 101 rotates relative to the oiling spindle 7 along with the oiling nozzle mounting seat 102, so that the oiling nozzle 101 sprays oil radially toward the inner hole surface, the coating effect is good, and the oiling area 114 can form a precise circumference.

[0070] Therefore, by setting the oiling spindle 7, the oiling nozzle mounting seat 102 and the elastic abutment wheel assembly 103, the oiling spindle 7 can be moved along the set circumference by the manipulator to meet the oiling needs of holes with different inner diameters. For holes with larger inner diameters, the manipulator can move along a larger set circumference. Conversely, for holes with smaller inner diameters, the manipulator can move along a smaller set circumference. In this way, the distance between the oiling nozzle 101 and the hole surface to be oiled can be flexibly adjusted, and the oiling controllability is good. Moreover, the oiling nozzle mounting seat 102 is sleeved on the lower end of the oiling spindle 7 and can rotate around the oiling spindle 7. When the oiling spindle 7 moves along the set circumference, the oiling nozzle 101 rotates relative to the oiling spindle 7 along with the oiling nozzle mounting seat 102 under the cooperation of the elastic abutment wheel assembly 103, so that the oiling nozzle 101 sprays oil radially toward the inner hole surface, and the coating effect is good. The oiling area can form a precise circumference, so the depth of the oiling area, the oiling area, etc. can be accurately controlled. In addition, the structure of this oiling mechanism is simple, and the manipulator can be a conventional manipulator. It only needs to be placed and positioned normally for the oiled product, and it is also suitable for automatic transfer and transportation of conventional automatic production lines.

[0071] The design focus of the present invention is that it mainly realizes automatic gluing and oiling on an all-in-one machine, with a small number of devices and a small occupied space. At the same time, it is beneficial to improve the efficiency of gluing and oiling. The cover and the shell are located on the same slide, which is also convenient for the subsequent assembly of the cover and the shell on the automated production line.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
