Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic brush bar straightening and feeding mechanism. Background Technology

[0002] As a core component for the conduction of electrical energy in electrical equipment such as motors and generators, brush bars establish a power transmission channel between external circuits and rotating parts through contact with commutators and slip rings. The installation accuracy of brush bars directly affects the electrical performance and operational stability of the equipment.

[0003] With the acceleration of industrial automation, automated equipment has been widely used in the production and assembly of brush strips to improve production efficiency and ensure product consistency. In the automated production process, the brush strip loading stage is a crucial step in accurately transferring materials from storage to subsequent processing stations. It requires precise and stable transfer of brush strips from the tray to the designated station. Existing brush strip loading mechanisms rely on automated tray unloading equipment to transport the trays, which are then moved to the gripping area by a transfer mechanism. A linear moving component then carries the gripping unit to perform the picking action. However, due to the movable gaps between the brush strips on the tray and the lack of targeted position correction design, adjacent, closely arranged brush strips are prone to displacement when the grippers pick them up. This displacement causes the actual position of the brush strips to deviate from the theoretical gripping position, reducing the accuracy of a single gripping operation and making it difficult to guarantee the accuracy of subsequent gripping and assembly, thus affecting the continuity of automated production and product quality. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an automatic brush strip straightening and feeding mechanism, which can effectively improve the gripping accuracy and clamping movement stability during the brush strip feeding process, ensuring the smooth operation of automated production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic brush strip straightening and feeding mechanism includes a support table, on which a material tray unloading device, a material tray transfer device, and a linear moving component are provided. The linear moving component is provided with a gripping mechanism for gripping the brush strip and a correction mechanism for correcting the position of the brush strip on the material tray. The gripping mechanism is provided with a positioning component to ensure the stability of the brush strip during clamping and movement.

[0007] Preferably, the gripping mechanism includes a drive component one and a mounting plate one. The output shaft of the drive component one is connected to a movable plate one. The movable plate one has a mounting frame plate at its lower end. A drive component two is mounted on the mounting frame plate. The mounting plate one has a connecting plate one and a clamping device. The output shaft of the drive component two is connected to the connecting plate one. The gripping mechanism can move up and down through the drive component one, and the drive component two can drive the clamping device to move horizontally, flexibly adjusting the gripping position to adapt to different gripping needs.

[0008] Preferably, the mounting frame plate has a guide rail on its lower side, and a slider that can move back and forth is fitted on the guide rail. The mounting plate is connected to the slider, and the guide rail and the slider cooperate to make the horizontal movement of the mounting plate and the clamping device more stable and smooth, and improve the accuracy of the gripping action.

[0009] Preferably, the positioning component includes a second mounting plate and a positioning plate. The positioning plate is mounted on the second mounting plate, and the positioning plate has a positioning end on its downward side to limit the position of the brush strip. The second mounting plate is mounted on the clamping device, and the positioning end directly limits the position of the brush strip. During the clamping process, the position of the brush strip can be firmly constrained to prevent it from shifting during gripping and movement, thus ensuring stability during gripping.

[0010] Preferably, the positioning end is provided in multiple locations, which are located on both sides and the middle of the positioning plate. The multiple positioning ends are distributed on both sides and the middle of the brush strip to fix the brush strip from multiple directions, effectively preventing it from tilting during movement due to its long length and improving clamping stability.

[0011] Preferably, the correction mechanism includes a driving component three, the output shaft of the driving component three is connected to a moving plate two, the lower end of the moving plate two is provided with a mounting plate three, the mounting plate three is provided with a pushing component that can push the brush strip for position correction, the driving component three drives the pushing component to move up and down, so that it is accurately aligned with the brush strip on the material tray, providing a position basis for subsequent pushing correction actions.

[0012] Preferably, the pushing component includes a driving component four, the output shaft of the driving component four is connected to a moving plate three, a connecting plate two is provided below the moving plate three, and the connecting plate two is provided with multiple correction parts.

[0013] Preferably, the calibration part includes a calibration plate, which is provided with a calibration end for calibrating the position of the brush strip on the material tray. The calibration plate is installed below the second connecting plate, and the calibration end can directly contact the brush strip and push the brush strip to the bottom of the clamping device, so that the position of the brush strip is uniform before each gripping, and the clamping device can accurately grip the brush strip.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model pushes the brush strip to a preset position through the calibration end of the calibration mechanism, ensuring uniform position before gripping and improving gripping accuracy. The gripping mechanism uses a drive component to achieve vertical and horizontal movement, flexibly adapting to different gripping needs. The guide rail and slider work together to make the movement more stable, and multiple positioning ends set on the positioning component can be distributed on both sides and the middle of the brush strip. The positioning ends can limit the brush strip to prevent it from tilting and falling off during movement, thereby ensuring the stability of the clamping. Attached Figure Description

Example

[0028] Please see Figure 1-6 An automatic brush strip straightening and feeding mechanism includes a support table 1, on which a material tray unloading device 2, a material tray transfer device 3, and a linear moving component 4 are provided. The linear moving component 4 is provided with a gripping mechanism 5 for gripping the brush strip and a correction mechanism 6 for correcting the position of the brush strip on the material tray. The gripping mechanism 5 is provided with a positioning component to ensure the stability of the brush strip during clamping and movement. The linear moving component 4 can be a linear motor or other device capable of linear movement during use.

[0029] The gripping mechanism 5 includes a first drive component 51, a first movable plate 52, a mounting frame plate 53, a second drive component 54, a first mounting plate 56, a first connecting plate 57, a clamping device 58, a first guide rail 55, and a first slider. The first drive component 51 is mounted on the output movable plate of the linear motion assembly 4. The output shaft of the first drive component 51 is fixedly connected to the first movable plate 52, allowing the first drive component 51 to drive the first movable plate 52 to move up and down. The mounting frame plate 53 is fixedly attached to the lower end of the first movable plate 52. The second drive component 54 is fixedly mounted on the mounting frame plate 53. The first guide rail 55 is located on the lower side of the mounting frame plate 53, and a first slider is fitted onto the first guide rail 55. A movable slider is fixedly connected to a mounting plate 56. A connecting plate 57 and a clamping device 58 are also fixedly mounted on the mounting plate 56. The output shaft of the drive unit 54 is connected to the connecting plate 57. When the drive unit 54 is working, it can pull the connecting plate 57 and then drive the mounting plate 56 to move left and right along the guide rail 55, thereby realizing the horizontal position adjustment of the clamping device 58. When there are two or more rows of brush strips on the material tray, the drive unit 54 can drive the movement of the clamping device 58 to clamp and grab the brush strips at different positions. The clamping device 58 can be a pneumatic gripper when in use.

[0030] The positioning assembly includes a second mounting plate 59, a positioning plate 510, and a positioning end 511. The second mounting plate 59 is mounted on the clamping device 58, and the positioning plate 510 is fixed on the second mounting plate 59. The positioning plate 510 has a positioning end 511 on its downward side. The positioning end 511 has multiple positions located on both sides and the middle of the positioning plate 510. The positioning end 511 can contact the sides and the middle of the brush strip for positioning. Through multi-point contact positioning, the brush strip can be limited from multiple directions, which can effectively cope with the long brush strip and ensure the stability of the brush strip when it is clamped and moved.

[0031] The calibration mechanism 6 includes a driving component 61, a movable plate 62, a mounting plate 63, and a pushing assembly. The driving component 61 is also mounted on the output movable plate of the linear moving assembly 4. The output shaft of the driving component 61 is fixedly connected to the movable plate 62, and the driving component 61 can drive the movable plate 62 to move up and down. The lower end of the movable plate 62 is provided with a mounting plate 63 fixedly connected to it. The pushing assembly is mounted on the mounting plate 63, which includes a driving component 64, a movable plate 65, and a connecting component. Plate 2 66, correction plate 67 and correction end 68, and drive component 4 64 are fixedly installed below mounting plate 3 63. The output shaft of drive component 4 64 is fixedly connected to moving plate 3 65. Its connecting plate 2 66 is fixedly installed below moving plate 3 65. When there are multiple rows of brush strips on the material tray, multiple correction plates 67 can be provided. Multiple correction plates 67 correspond to the positions of multiple rows of brush strips respectively. The correction plate 67 is provided with a correction end 68. Through the correction end 68, it can contact the brush strip and push the brush strip to perform position correction.

[0032] During runtime, the process is as follows:

[0033] The tray unloading device 2 releases the bottommost tray from the stacked trays. The tray transfer device 3 receives the tray and moves it to a designated position below the gripping mechanism 5. The linear moving component 4 drives the correction mechanism 6 and the gripping mechanism 5 to move above the tray. The drive component 3 61 is activated, and its output shaft extends, driving the moving plate 2 62 downward. This causes the mounting plate 3 63, drive component 4 64, moving plate 3 65, positioning plate 510, correction plate 67, and correction end 68 to move downward together until the correction end 68 is reached. 8. Corresponding to the brush strip on the material tray, the drive unit 4 64 is then activated, its output shaft extends, and pushes the moving plate 3 65 to move towards the brush strip to be gripped. The correction end 68 contacts the brush strip and pushes it to the preset position, completing the position correction of the brush strip and ensuring that it is accurately aligned below the clamping device 58. After the correction is completed, the output shaft of the drive unit 4 64 retracts, driving the moving plate 3 65 and the correction end 68 to reset. The output shaft of the drive unit 3 61 retracts, driving the moving plate 2 62 and the entire pushing assembly to move upward and reset.

[0034] After the correction mechanism 6 finishes its movement and resets, the gripping mechanism 5 starts, the drive component 1 51 starts, its output shaft extends, and pushes the moving plate 1 52 to move downward. The moving plate 1 52 drives the mounting frame plate 53 to move downward together. During the downward movement, the positioning end 511 on the positioning component first contacts and positions the two sides and the middle of the brush strip. Then the clamping device 58 starts to grip the corresponding brush strip. After gripping, the output shaft of the drive component 2 54 resets, driving the clamping device 58 away from the material tray to reset. Then the brush strip is sent to the next processing station.

[0035] When gripping brush strips on the tray, if there are two or more rows of brush strips placed side by side on the tray, the output shaft of the second drive component 54 is activated, and the mounting plate 56 moves along the guide rail 55 through the connecting plate 57. This moves the clamping device 58 to another row of brush strips, enabling gripping of multiple rows of brush strips on the tray. During gripping, one strip is gripped from one row, then one strip is gripped from another row, and so on, until all brush strips on the tray are gripped.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
