Description

Technical Field

[0001] This utility model relates to the field of single-ring carbon strip processing technology, specifically a material transfer device for testing friction materials. Background Technology

[0002] Single-ring carbon strips, sometimes called carbon brushes or electric brushes, are commonly used in electric motors, generators and other rotating electrical equipment as sliding contact parts to conduct current. They are made of highly conductive and wear-resistant materials, such as graphite or graphite composites impregnated with metal, to ensure stable operation under high-speed and high-temperature conditions.

[0003] While the traditional method of manual feeding for testing is simple and direct, manual operation is usually slow, especially in frequently repetitive testing tasks, leading to a decrease in overall production efficiency. Workers are prone to fatigue after long hours of work, which may result in inconsistencies in parameters such as the position and force of each feeding, and it is also difficult to guarantee the accuracy of the placement each time, affecting the accuracy of the test results. Long-term reliance on manual feeding will increase labor costs. In the context of mass production, manual feeding is not only inefficient, but may also become a bottleneck on the production line, limiting the possibility of capacity expansion. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a material transfer device for friction material testing, comprising an operating table and a feeding conveyor, a pressing device, a visual inspection device, a cone depth detection device, an air blowing device, and a material transfer assembly installed on the operating table from left to right;

[0005] The material transfer assembly includes a push plate slidably connected to the operating table and a pusher unit installed to drive the push plate to move left and right. Multiple columns are fixed to the top of the push plate, and an upper plate is fixed between the tops of the multiple columns. A slider is slidably connected between two columns, and a concave block is slidably connected between two columns. Multiple lifting parts connected to the slider and the concave block are installed on the top of the upper plate. A rotating part is installed on the concave block. A clamping cylinder is installed on the rotating end of the rotating part and on the slider. The double clamping ends of the clamping cylinder at the first end are fixed with L-shaped clamping plates, and the double clamping ends of the remaining clamping cylinders are fixed with semi-circular clamping plates.

[0006] Furthermore, the pushing unit is a pushing cylinder mounted on the operating table, and the piston rod of the pushing cylinder is connected to the push plate.

[0007] Furthermore, the lifting unit consists of multiple downward-pushing cylinders mounted on the upper plate, with the piston rods of the multiple downward-pushing cylinders respectively fixed to the corresponding sliders and concave blocks.

[0008] Furthermore, the rotating part is a rotary cylinder mounted on the concave block, and the rotating end of the rotary cylinder is fixed to the corresponding clamping cylinder.

[0009] Furthermore, the operating table, upper plate, slider, and concave block are all equipped with a matching number of buffers.

[0010] Furthermore, the inner arc surface of the semi-circular clamping plate is provided with an inner groove, and the two L-shaped clamping plates are arc-shaped on opposite sides facing downwards.

[0011] Furthermore, a baffle is fixed at the tail end of the feeding conveyor, a photoelectric sensor is installed in the middle, and a mounting plate is fixed on the side. A limit cylinder is installed on the mounting plate, and a T-shaped limit plate is fixed to the piston rod of the limit cylinder. A V-shaped opening adapted to the product is formed on one side of the baffle.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This material handling equipment for friction material testing moves products carrying a carrier to a designated position via a feeding conveyor. A pushing and lifting unit, along with a front-end clamping cylinder, extends an L-shaped clamping plate into the inner ring of the carrier. The carrier is then spread to fix the product, which is then transferred to a pressing device for carrier rejection. A semi-circular clamping plate, in conjunction with the inner groove, lifts and limits the product, sequentially transferring it to a visual inspection device, a cone depth detection device, and an air blowing device for testing. A rotating unit flips the product midway through the process. This automated feeding improves efficiency, maintains consistent feeding, and prevents damage during clamping.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment of a friction material testing transfer device includes an operating table 1. From left to right, a feeding conveyor 2, a pressing device 18, a vision inspection device 19, a cone depth detection device 20, and an air blowing device 21 are installed on the operating table 1. A transfer assembly is also installed on the operating table 1, located on one side of the feeding conveyor 2 and distributed opposite to the pressing device 18, the vision inspection device 19, the cone depth detection device 20, and the air blowing device 21.

[0021] In the above structure, products are conveyed by a feeding conveyor. A circular carrier is inserted into the inner ring of the product. After being sent to the end, the product is sequentially transferred to the pressing device by a material transfer component to press out the carrier. When it is transferred to the vision inspection device, the product is rotated and flipped for defect detection. After the inspection is completed, the depth of the conical structure on the carbon strip is measured by a cone depth detection device. Finally, the product is transferred to the bottom of the air blowing device to clean impurities. Therefore, automated feeding can be achieved to improve efficiency and reduce manual intervention to reduce costs. At the same time, it can prevent damage to the product during the feeding process and ensure the consistency of the feeding position. It is also suitable for mass production.

[0022] like Figure 3 A baffle 22 is fixed at the tail end of the feeding conveyor 2, and a V-shaped groove adapted to the product is formed on the right side of the baffle 22. Therefore, when the product is conveyed, the product will enter the V-shaped groove, which serves as a limit and can also prevent the product from moving back and forth during the limiting process.

[0023] To further explain, a through-beam photoelectric sensor is installed in the center of the feeding conveyor 2, and a mounting plate 3 is fixed to the back of the sensor on its right side. A limit cylinder 4 is installed on the mounting plate 3, and a T-shaped limit plate 5 is fixed to the piston rod of the limit cylinder 4. When the product passes the through-beam photoelectric sensor, the limit cylinder will push the limit plate out, thus blocking and limiting the product and preventing damage caused by concentrated collisions between products.

[0024] like Figure 2In the indicated direction, the material transfer assembly includes a push cylinder 7 mounted on the operating table 1, and a push plate 6 slidably connected to and fixed to the piston rod of the push cylinder 7. Five pairs of uprights 8 are fixed to the top of the push plate 6. An upper plate 9 is fixed between the tops of each pair of uprights 8. Five push cylinders 15 are mounted on the upper plate 9, distributed between each pair of uprights 8. The piston rods of the leftmost three and the rightmost one push cylinder 15 are fixed to sliders 10 that slide against the corresponding two uprights 8. The piston rod of the second rightmost push cylinder 15... A concave block 16 is fixed and slides with two corresponding columns 8. A rotary cylinder 11 is installed on the back of the concave block 16. A clamping cylinder 12 is installed on the rotating end of the rotary cylinder 11 and the front of multiple sliders 10. An L-shaped clamping plate 13 is fixed on the double clamping ends of the rightmost clamping cylinder 12. The opposite sides of the downward protruding ends of the two L-shaped clamping plates 13 form an arc. The double clamping ends of the other clamping cylinders 12 are all fixed with relatively distributed semi-circular clamping plates 14. An inner groove is opened on the opposite side of the two opposite semi-circular clamping plates 14.

[0025] By forming a concave surface on the front of the concave block, the rotating end of the rotary cylinder is positioned within this concave surface. This allows the clamping cylinder on the rotating end to be aligned with the other clamping cylinders on the same axis. Initially, the two L-shaped clamping plates are closed. Through the cooperation of the pushing cylinder and the downward pushing cylinder, the push plate, slider, and concave block are moved, allowing the two L-shaped clamping plates to insert into the inner ring of the carrier. Then, the clamping cylinders open and fix the carrier, thus preventing damage to the product when unloading it from the feeding conveyor. The product is then moved into the pressing device to complete the pressing of the carrier. The product is removed, and then clamped by a clamping cylinder on the concave plate through a semi-circular clamping plate, so that the product is just in the inner groove, limiting the product and avoiding damage caused by direct hard clamping. Then, a rotating cylinder drives the product to flip over and place it on the vision inspection device to complete the damage detection operation. Then, with the help of subsequent clamping cylinders and semi-circular clamping plates, the product is transferred to the cone depth detection device and the blowing device in sequence to complete the detection of the inner cone depth and finally clean the impurities on the inspected product, realizing automated feeding and preventing product damage.

[0026] To further explain, two buffers 17 are installed on the surface of the operating table 1, which are opposite to the left and right sides of the push plate 6, respectively. Five buffers 17 are installed on the top of the upper plate 9, which are opposite to the corresponding sliders 10 and concave blocks 16, and buffers 17 are installed on the outer sides of the sliders 10 and concave blocks 16. The buffers limit the movement of the push plate and sliders, and also buffer the impact of the push plate and sliders.

[0027] The working principle of the above embodiments is as follows:

[0028] The product carrying the carrier is transferred via a feeding conveyor. After passing through a photoelectric sensor, a limit cylinder drives a limit plate to push out and block the product behind it until the product contacts the stop block. At this point, the L-shaped clamp is also located above the inner ring of the carrier. By operating a push cylinder, the slider and concave block move downwards, positioning the L-shaped clamp within the inner ring of the carrier. Then, a clamping cylinder opens the clamp, securing the product by fixing the carrier. Finally, through the reset of the push cylinder and the cooperation of the push cylinder, the product is transferred to the pressing device to complete the carrier removal. After the removal is complete... The product is clamped by a semi-circular clamping plate driven by a clamping cylinder on a concave block. The product is transferred by limiting its position in the inner groove. Therefore, during the transfer process, excessive clamping force is avoided to prevent damage to the product. Then, when the product is moved from the pressing device to the vision inspection device, the rotating cylinder drives the clamping cylinder to rotate and flip the product before placing it on the vision inspection device for inspection. After the inspection is completed, the product is transferred to the cone depth detection device and the blowing device in sequence by the remaining clamping cylinders, thus realizing the function of automated material transfer.
