Abstract
Description
Technical Field
[0001] This application relates to the field of motor manufacturing, and in particular to a friction plate angle correction device and installation equipment. Background Technology
[0002] Friction plates are a crucial component inside brushed motors. In current technology, friction plates are supplied in bags, resulting in random and arbitrary angles. During motor manufacturing, the friction plate needs to be inserted and installed inside the motor. During installation, it is essential to ensure that the mounting angle of the friction plate's positioning groove perfectly aligns with the mounting boss inside the motor (current technical standards require extremely high precision in this alignment). If the friction plate's mounting angle is misaligned, it will collide with the mounting boss during insertion into the motor, causing abnormal operating conditions and leading to product scrap or rework. Summary of the Invention
[0003] This application provides a friction pad angle correction device and installation equipment, which can achieve precise installation of the friction pad and reduce the frequency of abnormal operating conditions.
[0004] The first solution, as disclosed in this application embodiment, is a friction pad angle correction device, comprising:
[0005] The first calibration mechanism includes a first slide rail, a first sliding plate, a second slide rail, a connecting frame, and a vacuum suction cylinder. The first slide rail is fixedly installed. The first sliding plate is installed on the first slide rail and can slide in the height direction via the first slide rail. The second slide rail is installed on the first sliding plate. The connecting frame is installed on the second slide rail and can slide in the first horizontal direction via the second slide rail. The vacuum suction cylinder is installed on the connecting frame, and a first positioning protrusion is provided on the inner peripheral wall of the vacuum suction cylinder. A positioning groove is provided on the friction plate, and the first positioning protrusion can be inserted into the positioning groove.
[0006] The second calibration mechanism includes a mounting frame, a vacuum suction rod, a contour calibration cylinder, and an elastic element. Along the first horizontal direction, the mounting frame is positioned on one side of the first calibration mechanism, and a vertically penetrating sliding hole is provided on the mounting frame. The vacuum suction rod passes through the sliding hole, and its upper end face is provided with a first suction hole for adsorbing friction pads, which communicates with an external negative pressure unit. The friction pads on the vacuum suction cylinder can be transferred to the upper end face of the vacuum suction rod. The contour calibration cylinder is coaxially sleeved around the outer periphery of the vacuum suction rod, and its inner periphery is provided with second positioning protrusions corresponding one-to-one with the positioning grooves. The projection of the vacuum suction cylinder in the height direction at least partially overlaps with the upper end face of the contour calibration cylinder. The elastic element connects the contour calibration cylinder and the vacuum suction rod, and the elastic element can provide an upward elastic force to the contour calibration cylinder.
[0007] Secondly, embodiments of this application disclose a friction pad installation device, including a line, a pressing unit, a tray lifting unit, and an angle correction device;
[0008] The production line is located on one side of the angle correction device along the first horizontal direction. A tray is provided on the production line, and motor parts are provided on the tray. The length direction of the production line is configured as the second horizontal direction, and the first horizontal direction and the second horizontal direction intersect perpendicularly.
[0009] The pallet lifting unit is located on one side of the angle correction device along the first direction and is used to lift the pallets on the production line.
[0010] The pressing unit includes a third telescopic drive unit, a pressure plate, and a pressure rod. The third telescopic drive unit is located above the line body, and the pressure plate is connected to the telescopic end of the third telescopic drive unit. The pressure plate is driven to move in the height direction by the third telescopic drive unit. The pressure rod is vertically connected to the side of the pressure plate away from the third telescopic drive unit. The end of the pressure rod away from the third telescopic drive unit can abut against the second positioning surface on the motor parts.
[0011] The friction plate angle correction device and installation equipment of this application have at least the following beneficial effects:
[0012] The angle correction device of this application is designed with a two-stage correction mechanism to ensure that the friction plate is at a predetermined angle before installation, thereby ensuring installation efficiency and success rate. The first correction mechanism moves the vacuum suction cylinder downwards via a first slide rail, allowing the vacuum suction cylinder to fit onto the outer circumference of the friction plate. During this downward movement, the first positioning protrusion inserts into the positioning groove of the friction plate, achieving initial positioning and providing a prerequisite for subsequent secondary precise positioning. The vacuum suction cylinder has internal suction force, which firmly holds the friction plate. Then, the second slide rail moves the vacuum suction cylinder to directly above the vacuum suction rod. The vacuum suction cylinder then moves downwards and releases the friction plate. Due to the suction force of the first suction hole on the upper end face of the vacuum suction rod, the friction plate is adsorbed onto the upper end face of the vacuum suction rod. Meanwhile, the vacuum suction cylinder... During the movement, the elastic element and the contouring correction cylinder are pressed downwards. After the vacuum suction cylinder is lifted, due to the reset effect of the elastic element, the second positioning protrusion on the inner circumferential wall of the contouring correction cylinder is inserted upwards into the positioning groove of the friction plate, thereby achieving secondary precise positioning. It should be noted that if the second positioning protrusion does not fit against the inner wall of the positioning groove, it means that the friction plate is not at the predetermined angle. At this time, the lower surface of the friction plate will not be completely and tightly fitted against the upper end face of the vacuum suction rod, which will cause the external negative pressure unit to report an error (because the friction plate does not tightly cover the first suction hole, which will break the negative pressure state in the first suction hole or the negative pressure value will not reach the predetermined threshold). At this time, the vacuum suction cylinder moves downwards again to press the elastic element and the contouring correction cylinder, and then releases the contouring correction cylinder again. The second positioning protrusion is inserted upwards into the positioning groove again to achieve re-correction. In this embodiment, a primary and a secondary correction mechanism are designed. The primary correction mechanism (first correction mechanism) can initially position the angle of the friction plate, providing a prerequisite for the precise correction of the secondary correction mechanism (second correction mechanism). Without the primary correction mechanism for initial correction, the second positioning protrusion cannot be roughly aligned with the positioning groove of the friction plate and inserted during the secondary correction. In this case, when the contour correction cylinder springs up, it may directly lift the friction plate out of the suction range of the first suction hole, which will greatly increase the frequency of production line abnormalities. The spring-loaded contour correction cylinder designed in this application can simulate the downward slapping action of a human hand and perform secondary elastic correction on the friction plate that has not reached the predetermined angle, thereby achieving precise correction of the friction plate and reducing the frequency of production line abnormalities.

[0049] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.
[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.
[0051] This application discloses an angle correction device 100 for a friction plate and an installation device 200. The angle correction device 100 is used to correct the angle of the friction plate 300 before installation, and the installation device 200 is used to install the corrected friction plate 300 and the motor parts 400 together.
[0052] like Figures 1 to 3 As shown, the structure of the friction plate 300 in this embodiment will be described first. The friction plate 300 is generally circular in shape, and has a plurality of positioning portions 301 (six positioning portions) on its outer circumference. Along the circumference of the friction plate 300, the plurality of positioning portions 301 are equidistantly arranged on the outer circumference of the friction plate 300, and a positioning groove 302 is formed between two adjacent positioning portions 301; as Figures 1 to 3 As shown, the inner wall of the positioning groove 302 includes a first inner wall 3021, a second inner wall 3022, a third inner wall 3023, and a fourth inner wall 3024. The first inner wall 3021, the second inner wall 3022, the third inner wall 3023, and the fourth inner wall 3024 are all inclined surfaces. The first inner wall 3021 and the third inner wall 3023 are arranged symmetrically in the upper and lower parts, and the second inner wall 3022 and the fourth inner wall 3024 are arranged symmetrically in the upper and lower parts.
[0053] like Figures 4 to 6 As shown, in this embodiment, the friction plate 300 needs to be installed inside the motor component 400. The motor component 400 (e.g., a motor housing) has a channel 401 inside. A mounting boss 402 is provided on the inner peripheral wall of the channel 401. The outer side wall of the mounting boss 402 can fit against the inner side wall of the positioning groove 302, thereby restricting the position of the friction plate 300 within the channel 401. A second positioning surface 403 is provided at the upper end of the motor component 400. The second positioning surface 403 is designed as a horizontal machined surface for positioning the motor component 400.
[0054] like Figure 7 and Figure 8 As shown, the angle correction device 100 in this embodiment includes a first correction mechanism 20, a second correction mechanism 30, a feeding mechanism 10, and a driving mechanism 40. The feeding mechanism 10 transports the material to a designated position. The first correction mechanism 20 performs initial positioning of the material (friction plate 300) and transfers it to the second correction mechanism 30. The second correction mechanism 30 and the first correction mechanism 20 cooperate to perform precise secondary positioning of the friction plate 300. The driving mechanism 40 can lift the precisely positioned friction plate 300 to the installation position for installation.
[0055] like Figures 9 to 11As shown, the feeding mechanism 10 includes a vibratory feeder 11, a material conveying channel 12, and a cutting unit 13. A spirally rising material rising channel 14 is provided on the inner peripheral wall of the vibratory feeder 11. The inlet end 141 of the material rising channel corresponds to the inner bottom surface of the vibratory feeder 11. The inlet end of the material conveying channel 12 is connected to the outlet end 142 of the material rising channel, and the two can communicate to form a channel for the friction plate 300 to pass through. The outlet end 121 of the material conveying channel extends below the first correction mechanism 20. The specific structure of the vibratory feeder 11 can be found in existing technology.
[0056] The feeding principle is as follows: the bagged material is poured into the vibrating plate 11, which can generate vibration. The friction plate at the bottom of the vibrating plate 11 is shaken into the material rising channel 14 by the vibrating plate 11. The friction plate 300 is shaken upward spirally along the material rising channel 14. The friction plate 300 is shaken into the material conveying channel 12 and conveyed along the inlet end to the outlet end of the material conveying channel 12.
[0057] In some preferred embodiments, a material sensor 15 is connected to the material conveying channel 12. The material sensor 15 is used to detect whether there is material passing through the material conveying channel 12, which facilitates intelligent production.
[0058] The cutting unit 13 includes a cutting block 131 and a cutting slide rail 132. The cutting block 131 is provided with a material retainer 1311 and a receiving port 1322, which are arranged sequentially along a second horizontal direction. When the material retainer 1311 corresponds to the outlet end 121 of the material conveying channel in a first horizontal direction, the material retainer 1311 can block the outlet end 121 of the material conveying channel, stopping material discharge. Conversely, when the receiving port 1322 corresponds to the outlet end 121 of the material conveying channel in a first horizontal direction... Correspondingly, the friction plate 300 can be connected from the outlet end 121 of the material conveying channel to the receiving port 1322; the function of the cutting slide rail 132 is to drive the cutting block 131 to move in the second horizontal direction, thereby switching the correspondence between the material guard 1311 and the receiving port 1322 and the outlet end 121 of the material conveying channel. The cutting slide rail 132 is set on the workbench 16 through the first bracket 133, and the cutting slide rail 132 is connected to the cutting block 131. The cutting slide rail 132 can drive the cutting block 131 to move in the second horizontal direction.
[0059] In the embodiments of this application, the first horizontal direction and the second horizontal direction intersect perpendicularly in the horizontal plane.
[0060] In this embodiment, the feeding mechanism 10 is designed to feed the friction plates 300 sequentially. The discharge rate is controlled by the cutting unit 13. When discharge is needed, a friction plate 300 is connected through the receiving port 1322. When discharge is not needed, the outlet end 121 of the material conveying channel can be blocked by switching the material stop 1311 of the cutting block 131.
[0061] like Figure 12 As shown, the first correction mechanism 20 includes a first slide rail 21, a first sliding plate 22, a second slide rail 23, a connecting frame 24, and a vacuum suction cylinder 25;
[0062] The first slide rail 21 is mounted on the workbench 16 via the second bracket 26, and the sliding direction of the first slide rail 21 is configured in the height direction; the first sliding plate 22 is disposed on the first slide rail 21, and the first slide rail 21 can drive the first sliding plate 22 to move in the height direction; the second slide rail 23 is disposed on the first sliding plate 22, and the sliding direction of the second slide rail 23 is configured in the first horizontal direction; the connecting frame 24 is disposed on the second slide rail 23, and the second slide rail 23 can drive the connecting frame 24 to slide in the first horizontal direction; the vacuum suction cylinder 25 is disposed at the end of the connecting frame 24 away from the second slide rail 23, and the vacuum suction cylinder 25 can be driven by the second slide rail 23 to be directly above the receiving port 1322 of the cutting unit 13, and the vacuum suction cylinder 25 can suck up and correct the friction plate 300 at the receiving port 1322.
[0063] like Figures 13 to 15 As shown, the vacuum suction cylinder 25 is cylindrical in shape. The vacuum suction cylinder 25 includes two sections, an upper section connected to the connecting frame 24 and a lower section coaxially fitted onto the outer circumference of the friction plate 300. The vacuum suction cylinder 25 has an inner bottom surface (i.e., the inner bottom surface 251 of the vacuum suction cylinder). A second suction hole 252 is provided on the inner bottom surface. The second suction hole 252 is connected to an external negative pressure unit (not shown). The external negative pressure unit can generate negative pressure, so that the second suction hole 252 has suction force, which facilitates the suction of the friction plate 300 at the receiving port 1322.
[0064] like Figures 13 to 15 As shown, a first positioning protrusion 253 is provided on the inner bottom surface 251 of the vacuum suction cylinder. The first positioning protrusion 253 can be inserted downward into any one of the positioning slots 302 of the friction plate 300, thereby realizing the initial positioning of the friction plate 300.
[0065] In some preferred solutions, such as Figures 13 to 15As shown, the overall shape of the first positioning protrusion 253 is V-shaped. Specifically, the outer surface of the first positioning protrusion 253 includes a first inclined surface 2531 and a second inclined surface 2532, which are symmetrically arranged. The first inclined surface 2531 can wedge with the first inner sidewall 3021, and the second inclined surface 2532 can wedge with the second inner sidewall 3022. By designing the outer surface of the first positioning protrusion 253 as an inclined surface, during the process of the first positioning protrusion 253 being inserted downward into the positioning groove 302, the wedge-shaped engagement of the inclined surface forces the friction plate 300 to rotate at a certain angle, thereby achieving the initial alignment (i.e., initial positioning) of the friction plate 300.
[0066] like Figure 16 and Figure 17 As shown, the second correction mechanism 30 includes a mounting frame 31, a vacuum suction rod 32, a contour correction cylinder 33, and an elastic element 34;
[0067] The mounting bracket 31 is disposed on one side of the first correction mechanism 20 (specifically, the vacuum suction cylinder 25) along the first horizontal direction. A vertically penetrating sliding hole is provided at the center of the mounting bracket 31. The vacuum suction rod 32 is coaxially disposed in the sliding hole and can slide up and down relative to the sliding hole. At least a portion of the vacuum suction rod 32 protrudes upward from the outside of the mounting bracket 31, and the upper end face 321 of the vacuum suction rod is designed as a horizontal machined surface. A first suction hole 322 is provided at the center of the upper end face. The first suction hole 322 is connected to an external negative pressure unit. The external negative pressure unit can generate negative pressure in the first suction hole 322, thereby making the upper end face 321 of the vacuum suction rod have suction force to adsorb the friction plate 300. The contour correction cylinder 33 is coaxially sleeved on the part of the vacuum suction rod 32 that protrudes from the outside of the mounting bracket 31. Multiple (six) second positioning points are provided on the inner peripheral wall of the contour correction cylinder 33. The second positioning protrusions 331 are equidistantly arranged along the circumference of the contouring correction cylinder 33. Each second positioning protrusion 331 corresponds one-to-one with a plurality of positioning grooves 302 of the friction plate 300. These second positioning protrusions 331 can be inserted into the positioning grooves 302 to achieve high-precision angle correction. The elastic element 34 is coaxially sleeved on the outer periphery of the vacuum suction rod 32. A shoulder mounting surface 323 is provided on the outer periphery of the vacuum suction rod 32. The elastic element 34 is located between the shoulder mounting surface 323 and the lower surface of the contouring correction cylinder 33. The axial ends of the elastic element 34 are connected to the shoulder mounting surface 323 and the contouring correction cylinder 33, respectively. The extension and retraction direction of the elastic element 34 is configured in the height direction (i.e., the axial direction of the vacuum suction rod 32). When the contouring correction cylinder 33 moves downward, the elastic element 34 is compressed, providing an upward elastic force to the contouring correction cylinder 33. In this embodiment, the elastic element 34 is configured as a spring.
[0068] The inner diameter of the vacuum suction cylinder 25 (specifically the lower section of the vacuum suction cylinder 25) is larger than the outer diameter of the vacuum suction rod 32 and smaller than the outer diameter of the contour correction cylinder 33. When the vacuum suction cylinder 25 is located directly above the vacuum suction rod 32 and the contour correction cylinder 33, the projection of the vacuum suction cylinder 25 in the height direction at least partially overlaps with the upper end face of the contour correction cylinder 33. This ensures that the vacuum suction cylinder 25 will not interfere with the vacuum suction rod 32 when it moves downward, and at the same time, the vacuum suction cylinder 25 can push the contour correction cylinder 33 downward.
[0069] In some preferred methods, such as Figure 17 As shown, the second positioning protrusion 331 has a V-shaped overall shape. Specifically, the second positioning protrusion 331 has a third inclined surface 3311 and a fourth inclined surface 3312. The third inclined surface 3311 can be tightly fitted with the third inner wall 3023 of the positioning groove 302, or the fourth inclined surface 3312 can be tightly fitted with the fourth inner wall 3024 of the positioning groove 302. As long as one of the third inclined surface 3311 and the fourth inclined surface 3312 on the second positioning protrusion 331 is tightly fitted with the inner wall of the positioning groove 302, accurate positioning (i.e., accurate correction) can be achieved. In this embodiment, the second positioning protrusion 331 is designed in a V-shape so that during the correction process, the friction plate 300 is forced to rotate at a certain angle, ensuring that the friction plate 300 is at a predetermined installation angle.
[0070] In some preferred methods, such as Figure 17 As shown, a radially extending guide protrusion 324 is provided on the outer periphery of the vacuum suction rod 32, and a guide groove 332 is provided on the contouring correction cylinder 33. The length direction of the guide groove 332 is consistent with the axial direction of the vacuum suction rod 32. At least a portion of the guide protrusion 324 is radially inserted into the guide groove 332. The guide groove 332 and the guide protrusion 324 can ensure the stability of the relative movement between the contouring correction cylinder 33 and the vacuum suction rod 32, and at the same time, can limit the vertical movement of the contouring correction cylinder 33. That is, the guide protrusion 324 abuts against the contouring correction cylinder 33 to prevent it from moving excessively upward.
[0071] The working principle of the second calibration mechanism 30 is as follows: Figure 18 and Figure 19As shown, the vacuum suction cylinder 25 drives the friction plate 300 to move laterally along the first horizontal direction to a coaxial position directly above the vacuum suction rod 32. Driven by the first slide rail 21, the vacuum suction cylinder 25 moves downward, and the friction plate 300 inside the vacuum suction cylinder 25 also moves downward. After the friction plate 300 touches the upper end face 321 of the vacuum suction rod, the second suction hole 252 inside the vacuum suction cylinder 25 stops adsorbing the friction plate 300, while the first suction hole 322 on the upper end face of the vacuum suction rod 32 uses negative pressure to adsorb the friction plate 300. The friction plate 300 completes the conversion adsorption (i.e., from adsorption through the second suction hole 252 to...). (If the first suction hole 322 is used for adsorption), as the vacuum suction cylinder 25 will press down on the elastic element 34 and the contour correction cylinder 33 during the descent, when the vacuum suction cylinder 25 is withdrawn upward, the contour correction cylinder 33 will reset upward under the action of the elastic element 34. The multiple second positioning protrusions 331 on the inner peripheral wall of the contour correction cylinder 33 will also be inserted upward into the positioning groove 302 of the friction plate 300. The wedge-shaped cooperation between the third inclined surface 3311 or the fourth inclined surface 3312 and the inner side wall of the positioning groove 302 will force the friction plate 300 to rotate at a certain angle, thereby achieving the purpose of angle correction.
[0072] It should be noted that: 1. Only when the third inclined surface 3311 or the fourth inclined surface 3312 of the second positioning protrusion 331 is tightly fitted with the inner wall (i.e., the third inner wall 3023 or the fourth inner wall 3024) of the positioning groove 302 can the lower surface of the friction plate 300 be tightly fitted with the upper end face 321 of the vacuum suction rod. Also, only when the second positioning protrusion 331 and the positioning groove 302 of the friction plate 300 are in a one-to-one correspondence are the friction plate 300 at the correct installation angle. 2. Because the first suction hole 322 is connected to the external negative pressure... Since the connection between the elements generates suction, the negative pressure at the first suction hole 322 position can be used to determine whether the lower surface of the friction plate 300 is tightly attached to the upper end face 321 of the vacuum suction rod. If the lower surface of the friction plate 300 is not tightly attached to the upper end face 321 of the vacuum suction rod, it means that there is a gap between the lower surface of the friction plate 300 and the upper end face 321 of the vacuum suction rod. External air pressure will enter the first suction hole 322 from the gap position and break the vacuum state of the first suction hole 322. In this case, the external negative pressure unit will report an error.
[0073] When the external negative pressure unit reports an error, the vacuum suction cylinder 25 presses the elastic element 34 and the contour correction cylinder 33 downward again, and then releases the contour correction cylinder 33 again, so that the contour correction cylinder 33 resets again under the action of the elastic element 34 and is corrected again.
[0074] In this embodiment, the designed spring-loaded contour correction cylinder 33 can improve the fault tolerance rate, achieve completely unmanned operation, and reduce the frequency of abnormalities.
[0075] like Figure 20As shown, the drive mechanism 40 includes a third slide rail 41, a second sliding plate 42, a guide rail 43, a moving frame 44, a first telescopic drive unit 45, and a second telescopic drive unit 46; the drive mechanism 40 is used to install the friction plate 300 after the angle correction is completed into the motor part 400.
[0076] Along the first horizontal direction, the third slide rail 41 is located on one side of the first correction mechanism 20 (specifically, on one side of the vacuum suction cylinder 25), and the sliding direction of the third slide rail 41 is configured in the first horizontal direction; the second sliding plate 42 is disposed on the third slide rail 41, and the second sliding plate 42 is driven to slide in the first horizontal direction by the third slide rail 41. In this embodiment, the third slide rail 41 can drive the second sliding plate 42 to slide directly below the motor component 400; the guide rail 43 is vertically disposed on the second sliding plate 42, and the length direction of the guide rail 43 is configured in the height direction; the moving frame 44 is slidably disposed on the guide rail 43 along the height direction; the first telescopic drive unit 45 (e.g., servo cylinder, electric push rod, etc.) is disposed on On the second sliding plate 42, the output end of the first telescopic drive unit 45 is connected to the moving frame 44. The telescopic direction of the first telescopic drive unit 45 is configured in the height direction, and the moving frame 44 is driven to move up and down through the first telescopic drive unit 45. The second correction mechanism 30 is set on the upper surface of the moving frame 44 and can move up and down together with the moving frame 44. The second telescopic drive unit 46 (e.g., servo cylinder, electric push rod, etc.) is set on the second sliding plate 42. The output end of the second telescopic drive unit 46 is coaxially connected to the lower end of the vacuum suction rod 32. The telescopic direction of the second telescopic drive unit 46 is configured in the height direction, and the vacuum suction rod 32 is driven to move up and down relative to the mounting frame 31 and the moving frame 44 through the second telescopic drive unit 46. In some preferred embodiments, the drive mechanism 40 further includes a transition frame 47, which is slidably mounted on the guide rail 43 along the height direction and is located below the movable frame 44. The transition frame 47 is connected to the lower end of the vacuum suction rod 32, and the output end of the second telescopic drive unit 46 is connected to the transition frame 47. The second telescopic drive unit 46 can drive the transition frame 47 and the vacuum suction rod 32 to move up and down together.
[0077] The working principle of the drive mechanism 40 is as follows: after the second correction mechanism 30 has corrected the friction plate 300, the third slide rail 41 drives the guide rail 43 and the second correction mechanism 30 to move laterally along the first horizontal direction to below the motor part 400. Then, the first telescopic drive unit 45 drives the moving frame 44 to a certain height position, and the second telescopic drive unit 46 drives the vacuum suction rod 32 and the friction plate 300 on the upper surface of the vacuum suction rod 32 to extend into the motor part 400 for installation.
[0078] like Figure 21As shown in the figure, this application embodiment also discloses a friction pad installation device. The installation device 200 includes a line body 50, a pressing unit 60, a tray lifting unit 70, and an angle correction device 100.
[0079] The conveyor belt 50 is positioned on one side of the angle correction device 100 along the first horizontal direction. A tray 51 is mounted on the conveyor belt 50, and a motor component 400 is mounted on the tray 51. The tray 51 can transport the motor component 400 along the length direction of the conveyor belt 50. The length direction of the conveyor belt 50 is configured as the second horizontal direction.
[0080] The pallet lifting unit 70 is set on one side of the angle correction device 100 along the first horizontal direction via the third bracket 80. The pallet lifting unit 70 can move up and down. The pallet lifting unit 70 is located directly below the line body 50. When the pallet lifting unit 70 moves up and down, it can lift the pallet 51 off the line body 50 or put the pallet 51 back onto the line body 50.
[0081] Among them, the mounting bracket 31 of the second correction mechanism 30 can pass upward through the tray 51 under the drive of the second telescopic drive unit 46, and push the motor parts 400 on the tray 51 upward.
[0082] like Figure 22 and Figure 23 As shown, the pressing unit 60 includes a third telescopic drive unit 61, a pressure plate 62, and a pressure rod 63. The third telescopic drive unit 61 is positioned directly above the line body 50 via a third bracket 80. The output end of the third telescopic drive unit 61 (e.g., a servo cylinder, telescopic push rod, etc.) is connected to the pressure plate 62, and the telescopic direction of the third telescopic drive unit 61 is configured as the height direction. The pressure plate 62 is driven to move up and down by the third telescopic drive unit 61. The pressure rod 63 is vertically connected to the side of the pressure plate 62 away from the third telescopic drive unit 61. The pressure plate 62 can drive the pressure rod 63 to move downward. The lower end of the pressure rod 63 can abut against the motor component 400, thereby ensuring the stability of the motor component 400 when the friction plate 300 is installed.
[0083] In some actual working scenarios, due to installation errors or other factors, the extension direction of the third telescopic drive unit 61 or the axis of the pressure rod 63 is not completely vertical. When the pressure rod 63 applies pressure downward to the motor part 400, it may obliquely touch the motor part 400. This will cause the posture of the motor part 400 to shift or the motor part 400 to not be effectively pressed, which will lead to the failure of the installation of the friction plate 300.
[0084] To address the above problems, in the embodiments of this application, as follows: Figure 23As shown, a ball joint groove 631 is provided at the end of the pressure rod 63 away from the third telescopic drive unit 61 (i.e., the lower end of the pressure rod 63). A ball joint 632 is rotatably disposed within the ball joint groove 631. The ball joint 632 is provided with a first positioning surface 6321, which is located outside the ball joint groove 631. When the pressure rod 63 moves downward, the first positioning surface 6321 can fit against the second positioning surface 403 on the motor component 400. Since the ball joint 632 can rotate in any direction, even if there is an error in the angle of the pressure rod 63, the first positioning surface 6321 and the second positioning surface 403 can remain in contact. Finally, the lower part of the motor component 400 is pressed upward by the mounting bracket 31 of the second correction mechanism 30, while the upper part of the motor component 400 is pressed downward by the first positioning surface 6321 of the ball joint 632, which ensures the stability of the motor component 400.
[0085] This application also discloses a method for installing a friction pad, which is performed using the aforementioned installation device 200;
[0086] Step S1: The bagged material is poured into the vibratory feeder 11, the vibratory feeder 11 vibrates, and then the friction plate 300 in the vibratory feeder 11 is conveyed along the material rising channel 14 and the material conveying channel 12 to the outlet end 121 of the material conveying channel.
[0087] Step S2: The cutting block 131 switches positions under the drive of the cutting slide rail 132, so that the receiving port 1322 of the cutting block 131 corresponds to the outlet end 121 of the material conveying channel in the first horizontal direction. A friction plate 300 falls from the outlet end 121 of the material conveying channel into the receiving port 1322 of the cutting block 131. Then the cutting block 131 switches positions, so that the material retaining edge 1311 of the cutting block 131 blocks the outlet end 121 of the material conveying channel.
[0088] Step S3: The second slide rail 23 drives the vacuum suction cylinder 25 to move horizontally in the first horizontal direction to directly above the receiving port 1322. Then, the first slide rail 21 drives the vacuum suction cylinder 25 to move downward. The first positioning protrusion 253 on the inner peripheral wall of the vacuum suction cylinder 25 is inserted downward into any one of the positioning grooves 302 of the friction plate 300, and the outer side (sloping surface) of the first positioning protrusion 253 is in contact with the inner side wall of the positioning groove 302, so that the friction plate 300 rotates at a certain angle to achieve the initial positioning of the friction plate 300. After the first positioning protrusion 253 is inserted into place, the external negative pressure unit creates negative pressure in the vacuum suction cylinder 25 and tightly adsorbs the friction plate 300.
[0089] Step S4: The second slide rail 23 drives the vacuum suction cylinder 25 to move laterally in the first horizontal direction to the coaxial position directly above the vacuum suction rod 32. Then, the first slide rail 21 drives the vacuum suction cylinder 25 to move downward. When the lower surface of the friction plate 300 contacts the upper end face 321 of the vacuum suction rod, the negative pressure adsorption in the vacuum suction cylinder 25 is released. At the same time, negative pressure is generated in the first suction hole 322 on the upper end face of the vacuum suction rod, so that the lower surface of the friction plate 300 is adsorbed on the upper end face 321 of the vacuum suction rod.
[0090] Then the first slide rail 21 drives the vacuum suction cylinder 25 to rise upwards, and the contour correction cylinder 33 moves upwards under the action of the elastic element 34's restoring force. The second positioning protrusions 331 on the inner peripheral wall of the contour correction cylinder 33 are inserted into the positioning grooves 302 of the friction plate 300 one by one, and the outer side (sloping surface) of the second positioning protrusion 331 is in contact with the inner side wall of the positioning groove 302, so that the friction plate 300 rotates a small angle, thereby completing the angle correction of the friction plate 300 before installation.
[0091] When the negative pressure value at the first suction hole 322 position does not reach the set threshold, the external negative pressure unit reports an error to the external control system. The external control system controls the vacuum suction cylinder 25 to move downward again and pushes the contour correction cylinder 33 downward to a certain position. Then, the vacuum suction cylinder 25 is lifted up again and the contour correction cylinder 33 is released. Under the restoring force of the elastic element 34, the contour correction cylinder 33 moves upward again to achieve secondary correction.
[0092] Step S5: After the installation angle of the friction plate 300 is corrected, the third slide rail 41 of the drive mechanism 40 drives the second sliding plate 42, guide rail 43, moving frame 44 and the second correction mechanism 30 to move directly below the line body 50; the pallet lifting unit 70 lifts the pallet 51 on the line body 50 to a certain height.
[0093] The first telescopic drive unit 45 drives the movable frame 44 to move upward, and the second correction mechanism 30 set on the movable frame 44 also moves upward. During the upward movement of the mounting frame 31 of the second correction mechanism 30, the mounting frame 31 passes through the tray 51, and the upper surface of the mounting frame 31 contacts the motor part 400 on the tray 51, pushing the motor part 400 upward.
[0094] Step S6: The third telescopic drive unit 61 of the pressing unit 60 drives the pressure rod 63 and the ball head 632 at the end of the pressure rod 63 to move downward until the first positioning surface 6321 of the ball head 632 comes into contact with the second positioning surface 403 on the motor part 400. At this time, the motor part 400 is fixed.
[0095] Step S7: As Figure 24As shown, the second telescopic drive unit 46 of the drive mechanism 40 extends upward, driving the vacuum suction rod 32, the friction plate 300 on the upper surface of the vacuum suction rod 32, the contour correction cylinder 33 and the elastic element 34 to move upward together and insert into the channel 401 of the motor part 400. As the second telescopic drive unit 46 extends, the upper surface of the contour correction cylinder 33 abuts against the stepped surface in the channel 401, and the elastic element 34 is pressed. The elastic force of the elastic element 34 elastically pre-tightens the motor part 400 between the upper surface of the contour correction cylinder 33 and the first positioning surface 6321 of the ball head 632.
[0096] The vacuum suction rod 32 and the friction plate 300 continue to move upward until the mounting boss 402 in the channel 401 aligns with and is inserted into the positioning groove 302 of the friction plate 300 (there are small protrusions on the inner peripheral wall of the channel 401 to prevent the friction plate 300 from falling out of the channel 401). At this time, the installation is completed. The second telescopic drive unit 46 drives the vacuum suction rod 32, the friction plate 300 on the upper surface of the vacuum suction rod 32, the contour correction cylinder 33 and the elastic element 34 to retract downward. The motor parts 400 return to the tray 51 and are transported to the next station along the length of the line 50.
