Description

Technical Field

[0001] The invention relates to the technical field of semi-finished brake pad screening equipment, in particular to an automatic inspection equipment platform for brake pads. Background Art

[0002] After the traditional brake pads are processed by the grinder, due to different product models or shapes or deviations in density during the hot pressing process, there will be problems such as thickness deviation and product density deviation, that is, defective products will be produced. The defective products will be transported to the next processing equipment through the conveyor belt of the automated assembly line for the next process. The processed defective products still need to be scrapped, causing waste. The traditional automated assembly line lacks a structure for thickness and weight detection of semi-finished brake pads, so defective products cannot be removed in time, resulting in the defective products still being processed in the process, which not only occupies production resources, but also delays processing, resulting in processing efficiency. At the same time, when the brake pad is processed by the grinder and moved to the conveyor belt of the automated assembly line through the unloading equipment, the unloading direction of the unloading equipment cannot be fixed, so that the semi-finished brake pad will have the problem of reverse processing surface when it is unloaded onto the conveyor belt through the unloading equipment, that is, the processing surface of the semi-finished brake pad faces downward, causing the automated assembly line to automatically transfer it to the next process, resulting in the incorrect processing of the processing surface of the semi-finished brake pad, which in turn causes the brake pad to be scrapped. The traditional automated assembly line lacks a structure for detecting the direction of the processing surface of the semi-finished brake pad and flipping the semi-finished brake pad with the reverse processing surface. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides an automatic inspection equipment for brake pads to solve the problem that traditional semi-finished brake pad transportation equipment lacks a structure for detecting the weight, thickness and processing surface orientation of the brake pads and screening good and bad products.

[0004] In order to achieve the above-mentioned purpose, the present invention provides an automatic inspection equipment for brake pads, including a testing table, on which a conveyor belt for placing external brake pads to be processed and a transmission structure for driving the conveyor belt to drive the brake pads to be processed to perform transmission movement along the length direction of the testing table is provided. The conveyor belt is divided into a flipping area and a horizontal transmission area along its width direction, and vertical plates are erected on both sides of the testing table. The testing table is provided with a detection component for detecting the weight, thickness and processing surface orientation of the brake pads to be processed. The testing table is provided with a screening component for cooperating with the detection component to screen the quality of the external brake pads to be processed and move the brake pads to be processed to the flipping area or the horizontal transmission area according to the quality. The flipping area is provided with a flipping component for flipping the external brake pads to be processed in the flipping area to ensure that the processing surface of the brake pad is always displayed positively.

[0005] The above technical solution is beneficial in that: after the semi-finished brake pads processed by the grinder are unloaded onto the testing table through the unloading device, the conveyor belt is driven by the transmission structure to perform transmission movement, so that the semi-finished brake pads are transmitted from the starting end of the testing table to the end of the testing table. During the transmission process of the semi-finished brake pads, the semi-finished brake pads are firstly detected by the detection component for their weight. If the detection component detects that the weight of the semi-finished brake pads does not meet the preset weight range, the semi-finished brake pads are defective products, which can be removed from the testing table. If they meet the preset weight range, the semi-finished brake pads are continuously detected by the detection component, that is, the thickness of the semi-finished brake pads is detected. If the detection component detects that the thickness of the semi-finished brake pads does not meet the preset thickness range, the semi-finished brake pads are defective products, which can be removed from the testing table. If they meet the preset thickness range, the detection component continues to detect the semi-finished brake pads, that is, the direction of the processing surface of the semi-finished brake pads is detected. If the processing surface of the semi-finished brake pads faces downward, when the semi-finished brake pads move to the end of the testing table. It is flipped by a flipping piece so that its processed surface faces upward and enters the next process equipment under the drive of the conveyor belt for the next process; the above-mentioned technical setting prevents defective products that do not meet the thickness standard and the weight standard from being processed in the next process, thereby avoiding cost waste, thereby improving processing production efficiency and processing accuracy, and ensuring that the semi-finished brake pad can be processed normally with its processed surface facing upward when it is processed in the next process by a flipping piece, thereby improving processing efficiency and processing accuracy, and at the same time avoiding the problem of scrapping the semi-finished brake pad due to the processing surface facing downward being processed in the next process, thereby avoiding waste; in the above-mentioned technology, the detection component is communicated with the external intelligent industrial control equipment so that the operator can monitor the transportation and detection process of the semi-finished brake pad in real time through the intelligent industrial control equipment, and at the same time, the parameters of the preset thickness range and the preset weight range can be adjusted through the intelligent industrial control equipment to adapt to the different detection requirements of different products. The intelligent industrial control equipment is an existing technology, so its structure and communication connection method will not be described in detail.

[0006] The present invention is further arranged that: one end of the detection platform is a feed port for placing external brake pads to be processed on a conveyor belt, and the other end is a discharge port for connecting with external processing equipment. The detection component includes a weight detection sensor embedded in the end face of the feed port, and the end face of the detection end of the weight detection sensor is arranged flush with the end face of the feed port.

[0007] The benefits of adopting the above technical solution are: by installing a weight detection sensor, the weight of the semi-finished brake pad can be detected, that is, when the semi-finished brake pad is unloaded to the feed port through the unloading equipment, a certain gravity will be applied to the feed port, and the weight sensor can detect the weight of the semi-finished brake pad when passing through the weight sensor and generate weight data. The weight sensor can transmit the weight data to the external intelligent industrial control equipment. The external intelligent industrial control equipment receives the data and compares it with the preset weight range. When it meets the range, it is judged as compliant, otherwise it is judged as a defective product and a warning message is generated; the weight of the semi-finished brake pad can be detected by the setting of the above technology to avoid defective products from entering the next process for processing. The setting of the above technology improves the processing efficiency and processing accuracy of the semi-finished brake pad; the weight sensor in the above technology is a prior art, so its structure, function and installation position will not be described in detail.

[0008] The present invention is further provided with: a first frame plate is erected on the detection table along the width direction of the detection table, the bottom wall of the first frame plate is gap-matched with the end face of the conveyor belt, a plurality of movable shafts are arranged on the bottom wall of the first frame plate corresponding to the flipping area and the horizontal transmission area, and a movable groove is opened on the bottom wall of the first frame plate along the height direction of the first frame plate and corresponding to each movable shaft position, the detection component includes a plurality of distance sensors, a plurality of the distance sensors correspond one-to-one to a plurality of movable grooves and each distance sensor is arranged in the movable groove, a plurality of ends of the movable shafts are inserted into their respective corresponding movable grooves and gap-matched with adjacent sensor detection ends, a roller is arranged at the starting end of each movable shaft for contacting the surface of the brake pad to be processed outside, a reset spring is arranged on the inner peripheral wall of the movable groove, and the end of the reset spring is coaxially connected with the end of the movable shaft.

[0009] The benefits of adopting the above technical solution are: after the weight of the semi-finished brake pad is detected by the weight sensor, if it is a compliant product, it will continue to be transmitted through the conveyor belt. When it is transmitted to a certain position, it will contact some or all of the rollers. Because the semi-finished brake pad has a certain thickness, it can push the movable shaft by squeezing the rollers during transmission, that is, some rollers in contact with the semi-finished brake pad drive the corresponding movable shaft to shift in their respective movable grooves. At this time, the movable shaft moves toward the distance sensor in the movable groove. When the movable shaft does not move, the distance between the detection end of the distance sensor and the end of the movable shaft is defined as A. After the movable shaft moves and moves to a certain distance, the distance between the detection end of the distance sensor and the end of the movable shaft is defined as B. The value of A minus the value of B is the moving distance of the movable shaft, and then the thickness of the semi-finished brake pad is calculated. Multiple and multiple thickness detections are achieved through the cooperation of several distance sensors and several movable shafts, thereby improving the accuracy and efficiency of the detection data. In the above technology, the setting of rollers avoids the jamming of the semi-finished brake pad when it moves, and at the same time avoids the transmission of the semi-finished brake pad. The efficiency is affected; the setting of the reset spring in the above technology is used to reset the movable shaft through the mechanical deformation reset of the reset spring when the semi-finished brake pad no longer applies force to the roller, thereby ensuring that the next semi-finished brake pad can still cooperate with the roller, and at the same time, the setting of the reset spring is used to position and limit the movable shaft to avoid shaking or loosening of the movable shaft to affect the detection; the roller can be replaced with a universal wheel according to actual detection needs or actual transmission needs in the above technology, thereby avoiding affecting the transmission of the semi-finished brake pad; in the above technology, after the distance sensor detects the spacing difference, the spacing difference value will be transmitted to the external intelligent industrial control equipment, the intelligent working condition equipment receives the data and compares it with the preset thickness range, when it meets the range, it is judged as compliant, otherwise it is judged as a defective product and a warning message is generated; the thickness of the semi-finished brake pad can be detected through the setting of the above technology to avoid defective products from entering the next process for processing, and the setting of the above technology improves the processing efficiency and processing accuracy of the semi-finished brake pad; the distance sensor in the above technology is a prior art, so its structure, function and installation position will not be described in detail.

[0010] The present invention is further configured as follows: the two ends of the first frame plate are respectively connected to adjacent vertical plates, the detection component includes two laser rangefinders, the two laser rangefinders are respectively arranged on the inner walls of the two vertical plates and the emitting ends of the two laser rangefinders are arranged toward the inner walls of the vertical plates opposite to each other.

[0011] The advantages of adopting the above technical solution are as follows: after the thickness of the semi-finished brake pad is detected by the distance sensor, if it is a compliant product, it will continue to be transmitted via the conveyor belt. When it is transmitted to a certain position, the laser rangefinder detects the thickness of the semi-finished brake pad, and determines the flatness and thickness difference through three-point detection. After the laser rangefinder detects the thickness of the brake pad, it will generate a thickness value and transmit it to the external intelligent industrial control equipment. The external intelligent industrial control equipment receives the data and compares it with the preset thickness range. If it meets the range, it is judged to be compliant. Otherwise, it is judged to be a defective product and a warning message is generated. The thickness of the semi-finished brake pad can be detected by the setting of the above technology to avoid defective products from entering the next process for processing. The setting of the above technology improves the processing efficiency and processing accuracy of the semi-finished brake pad. The laser rangefinder in the above technology is a prior art, so its structure, function and installation position will not be described in detail.

[0012] The present invention is further configured as follows: a second frame is provided on the detection table, the second frame is arranged near the discharge port of the detection table, the detection component includes a strong metal detection sensor, the strong metal detection sensor is arranged on the bottom wall of the second frame and the detection end of the strong metal detection sensor is arranged toward the end face of the conveyor belt.

[0013] The advantages of adopting the above technical solution are as follows: after the thickness of the semi-finished brake pad is detected by the laser rangefinder, if it is a compliant product, it will continue to be transmitted via the conveyor belt. When it is transmitted to the detection plate position, the strong metal detection sensor detects the surface of the semi-finished brake pad, that is, detects the metal properties of the brake pad surface. If the metal properties of the brake pad surface are too strong, it proves that the processed surface of the brake pad is facing upward, which meets the premise of entering the next process for processing. If the metal properties of the brake pad surface are low, it proves that the processed surface of the brake pad is facing downward, which does not meet the premise of entering the next process for processing. At this time, the strong metal detection sensor will generate a corresponding signal and transmit it to the flipping part, so that the flipping part can flip the brake pad, thereby ensuring that the processing surface of the flipped brake pad faces upward, which meets the premise of entering the next process for processing; the above-mentioned technical setting can detect the direction of the processing surface of the semi-finished brake pad to avoid defective products from entering the next process for processing. The above-mentioned technical setting improves the processing efficiency and processing accuracy of the semi-finished brake pad; the strong metal detection sensor in the above-mentioned technology is a prior art, so its structure, function and installation position will not be described in detail.

[0015] The advantages of adopting the above technical scheme are as follows: after the semi-finished brake pad is detected by the strong metal detection sensor, it is transmitted to the swing arm via the conveyor belt. If the strong metal detection sensor detects that its processing surface is facing upward, the first motor starts and drives the swing arm to swing. At this time, the swing arm swings and abuts against the inner wall of the vertical plate close to the flipping area. At this time, the swing arm is relatively inclined, so that the brake pad moves along the inclined sealing plate to the flat transfer area and is transmitted to the next process equipment through the conveyor belt; if the strong metal detection sensor detects that its processing surface is facing downward, the first motor does not move. At this time, the swing arm abuts against the inner wall of the vertical plate close to the flat transfer area, and the swing arm is in a relatively inclined state, so that the brake pad can move along the inclined swing arm to the flipping area and enter the flipping part along with the conveyor belt; the above-mentioned technology is set up to classify brake pads with different processing surface directions to avoid brake pads with the processing surface facing downward entering the flat transfer area and entering the next process equipment.

[0017] The benefits of adopting the above technical solution are: when the semi-finished brake pad contacts the swing arm, the second motor starts and drives the first gear to rotate, and several second gears are meshed with each other, and the first gear is meshed with adjacent second gears, so that when the second gear rotates, it will drive the adjacent second gear to rotate, thereby realizing the synchronous rotation of several second gears, and when the second gear rotates, it will drive the rotating shaft to rotate, thereby realizing the synchronous rotation of several pulleys, and the rapid movement of the semi-finished brake pad is achieved through the rotation of the pulley and the cooperation with the semi-finished brake pad, so that the semi-finished brake pad can be quickly moved to the flat transfer area or the flipping area, thereby improving the transmission efficiency and transmission accuracy of the semi-finished brake pad, and avoiding the semi-finished brake pad from being stuck at the swing arm; in the above technology, the number of pulleys and the number of second gears can be set according to actual installation requirements and practical requirements, that is, the number of second gears is reduced and several second gears can be synchronously transmitted through a transmission belt or a transmission chain.

[0018] The present invention is further provided that: the flipping part includes a bracket arranged on one side of the detection table, the bracket is provided with a secondary sleeve and a main sleeve sleeved on the secondary sleeve, the bracket is arranged close to the flipping zone, the axial hole of the main sleeve is a rotating hole, a rotating groove is opened on the outer peripheral wall of the rotating hole, a third motor is arranged on the bracket, the output end of the third motor is connected with a first gear disk, a second gear disk is arranged on the outer peripheral wall at the center of the secondary sleeve, bearings are connected between the outer peripheral walls at both ends of the secondary sleeve and the inner peripheral wall of the rotating hole, the first gear disk and the second gear disk are partially meshed, and the axial hole of the secondary sleeve is an adjustment hole for inserting the brake pad to be processed in the flipping zone.

[0019] The advantages of adopting the above technical scheme are: when the semi-finished brake pad is transmitted to the adjustment hole of the auxiliary sleeve via the conveyor belt in the flipping zone, the third motor starts and drives the first sprocket to rotate, and the first sprocket is meshed with the second sprocket so that the second sprocket rotates synchronously. The rotation of the second sprocket drives the auxiliary sleeve to rotate in the rotating hole, and then drives the semi-finished brake pad to rotate, thereby realizing the flipping of the semi-finished brake pad, that is, the processed surface of the brake pad is changed from a downward state to an upward state, and after the brake pad is flipped, its part is located at the feeding port or the transport port of the next process; in the above technology, the main sleeve, the auxiliary sleeve and the third motor are arranged to realize the automatic flipping of the semi-finished brake pad, thereby improving the flipping efficiency and flipping accuracy, and then ensuring that the processed surface of the brake pad is facing upward. In the above technology, the bearing is arranged to improve the rotation accuracy and smoothness of the auxiliary sleeve during rotation, so as to avoid the jamming of the auxiliary sleeve.

[0020] The present invention is further provided that: a bottom plate and a top plate are provided in the adjustment hole, the bottom plate and the top plate are arranged opposite to each other and an adjustment groove for placing the brake pad to be processed is formed therebetween, the top surface of the bottom plate is a placement surface for placing the brake pad to be processed, electric push rods are provided at the four corners of the bottom plate, the four electric push rods are all embedded in the inner circumferential wall of the auxiliary sleeve, and the output ends of the four electric push rods are all connected to the bottom wall of the bottom plate.

[0021] The benefit of adopting the above technical solution is that before the brake pad is flipped, the electric push rod automatically starts and drives the bottom plate to rise toward the top plate until the bottom plate and the top plate are combined to clamp the brake pad. At this time, the brake pad is clamped and cannot shake or loosen, and then when the secondary sleeve rotates, the brake pad will not shake or loosen, affecting the flipping accuracy of the brake pad. At the same time, the cooperation between the top plate and the bottom plate can prevent the brake pad from falling or colliding with the inner wall of the adjustment hole after flipping, thereby preventing damage to the brake pad.

[0023] The benefits of adopting the above technical solution are: when the bottom plate and the top plate cooperate, the brake pads are clamped and limited by the contact between a number of driven wheels and a number of driving wheels and the brake pads, thereby preventing the brake pads from shaking or loosening. At the same time, after the flipping is completed, the driving motor is started to rotate the driving wheel, and then the brake pads are driven by a number of driving wheels to ensure that the brake pads are transmitted to the feeding port or transport port of the next process.
