Description

Technical Field

[0001] The utility model relates to the technical field of automatic inspection equipment for brake pads, in particular to automatic inspection equipment 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 hot pressing, problems such as thickness deviation and product density deviation may occur, that is, defective products will be produced. The defective products will be transported to the next processing equipment via the conveyor belt of the automated assembly line for the next processing step. The processed defective products will still 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 and reduces processing efficiency. At the same time, when the brake pads are 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 the semi-finished brake pads will have the problem of reversed processing surface when they are unloaded onto the conveyor belt through the unloading equipment, that is, the processing surface of the semi-finished brake pads faces downward, causing the automated assembly line to automatically transfer them to the next process, causing the processing surface of the semi-finished brake pads to be incorrectly processed, and thus causing the brake pads to be scrapped. The traditional automated assembly line lacks a structure for detecting the direction of the processing surface of the semi-finished brake pads and flipping the semi-finished brake pads with reverse processing surfaces. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides an automatic inspection equipment for brake pads, which solves 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.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an automatic inspection equipment for brake pads, including an inspection table, on which a conveyor belt for placing semi-finished brake pads from the outside and a transmission structure for driving the conveyor belt to drive the semi-finished brake pads to perform transmission movement along the length direction of the inspection table are provided, a weight detection part for detecting the weight of the semi-finished brake pads and a thickness detection part for detecting the thickness of the semi-finished brake pads are provided at the starting end of the inspection table, a strong metal detection part for detecting the direction of the processing surface of the semi-finished brake pads and a flipping part for cooperating with the strong metal detection part to ensure that the processing surface of the semi-finished brake pads is always displayed in the positive direction and flipping the semi-finished brake pads when the processing surface of the semi-finished brake pads is displayed in the reverse direction, the conveyor belt is divided into a flipping area and a flat transmission area along its width direction, and the flipping part is arranged close to the flipping area.

[0005] The benefit of adopting the above technical solution is that: after the semi-finished brake pads processed by the grinder are unloaded onto the inspection table through the unloading device, the transmission structure drives the conveyor belt to perform transmission movement, so that the semi-finished brake pads are transmitted from the starting end of the inspection table to the end of the inspection table. During the transmission of the semi-finished brake pads, the semi-finished brake pads pass through the weight detection parts so that the weight detection parts detect the weight of the semi-finished brake pads. If the weight detection parts detect that the weight of the semi-finished brake pads does not meet the preset weight range, then the semi-finished brake pads are defective products and can be removed from the inspection table. If they meet the preset weight range, the semi-finished brake pads can continue to be transmitted. During the movement of the semi-finished brake pads, the thickness detection parts detect their thickness. If the thickness detection parts detect that the thickness of the semi-finished brake pads does not meet the preset thickness range, then the semi-finished brake pads are defective products and can be removed from the inspection table. If they meet the preset thickness range, the semi-finished brake pads can continue to be transmitted. When the semi-finished brake pads are transmitted to the position of the strong metal detection parts, if the processing surface of the semi-finished brake pads is facing down, then when the semi-finished brake pads move to the end of the inspection table The flip part flips it so that the processed surface faces upward and enters the next process equipment under the drive of the conveyor belt for the next process; the setting of the above technology 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, thereby improving processing efficiency and processing accuracy, while avoiding the problem of scrapping the semi-finished brake pad due to the next process being processed with the processed surface facing downward, thereby avoiding waste; in the above technology, the weight detection part and the thickness detection part can be communicated with external intelligent industrial control equipment, so that the operator can monitor the transportation and inspection process of the semi-finished brake pad in real time through the intelligent industrial control equipment, and can also adjust the parameters of the preset thickness range and the preset weight range through the intelligent industrial control equipment to adapt to the different inspection 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 provided with: the weight detection component comprises a weight sensor embedded in the end surface of the starting end of the detection platform, and the detection end surface of the weight sensor is arranged flush with the end surface of the starting end of the detection platform.

[0007] The benefits of adopting the above technical solution are: when the semi-finished brake pads are unloaded to the starting end of the conveyor belt through the unloading equipment, the semi-finished brake pads will exert a certain gravity on the conveyor belt. When passing through the weight sensor, the weight sensor can detect the weight of the semi-finished brake pads 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 pads can be detected through 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 pads; the weight sensor in the above technology is an existing technology, so its structure, function and installation position will not be described in detail.

[0008] The utility model is further provided with: vertical plates are connected to both sides of the detection platform, the vertical plates are arranged perpendicular to the end face of the detection platform, and laser rangefinders for detecting semi-finished brake pads are arranged on the inner walls of the two vertical plates, and the laser rangefinders are thickness detection parts.

[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 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 through 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 an existing technology, so its structure, function and installation position will not be described in detail.

[0010] The utility model is further provided with: a detection plate is provided between the two vertical plates, a strong metal detection sensor is provided on the bottom wall of the detection plate, the detection end port of the strong metal detection sensor is arranged toward the conveyor belt, and the strong metal detection sensor is a strong metal detection part.

[0011] The benefits of adopting the above technical solution are: after the thickness of the semi-finished brake pad is tested by the laser rangefinder, if it is a compliant product, it continues 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, the metal properties of the brake pad surface are detected. If the metal properties of the brake pad surface are too strong, it proves that the processed surface of the brake pad is facing up, which meets the prerequisite for 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 down, which does not meet the prerequisite for 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 processed surface of the flipped brake pad faces up, which meets the prerequisite for entering the next process for processing; the setting of the above technology can detect the direction of the processed surface of the semi-finished brake pad 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 strong metal detection sensor in the above technology is an existing technology, so its structure, function and installation position will not be described in detail.

[0012] The present invention is further provided with: a positioning plate is connected between the two vertical plates, the positioning plate is located between the detection plate and the end of the detection platform, the bottom wall of the positioning plate is connected with a partition for separating the flipping area and the horizontal transfer area, the front end of the partition is swingably provided with a sealing plate for closing the horizontal transfer area, the end of the sealing plate is abutted against the inner wall of the vertical plate close to the horizontal transfer area, the sealing plate and the positioning plate are relatively inclined, and a driving motor is provided on the partition for driving the sealing plate to swing to clear the horizontal transfer area or close the horizontal transfer area, and the output shaft of the driving motor is connected to the starting end of the sealing plate.

[0013] The benefits of adopting the above technical solution are: after the semi-finished brake pad is detected by the strong metal detection sensor, it is moved to the partition via the conveyor belt. At this time, if the strong metal detection sensor detects that its processing surface is facing upward, the drive motor is started and drives the closing plate to swing. At this time, the closing plate swings and abuts against the inner wall of the vertical plate close to the flipping area. At this time, the closing plate and the partition are relatively inclined, so that the brake pad moves along the inclined closing plate to the flat transfer area and is transmitted to the next process equipment through the transmission belt; if the strong metal detection sensor detects that its processing surface is facing downward, the drive motor does not move. At this time, the closing plate abuts against the inner wall of the vertical plate close to the flat transfer area, and the closing plate and the partition are relatively inclined, so that the brake pad can move along the inclined closing plate to the flipping area and move into the flipping part along the transmission belt; the above-mentioned technology is set 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.

[0014] The utility model is further provided with: the flipping part includes a bracket arranged on one side of the detection platform and a rotating shaft arranged on the bracket, the rotating shaft is arranged near the end position of the detection platform and the opening direction of the rotating shaft is arranged parallel to the width direction of the conveyor belt, the bracket is provided with a servo motor for driving the rotating shaft to rotate axially, the outer peripheral wall of the rotating shaft is provided with a fixed plate and a displacement plate sliding along the height direction of the detection platform, the fixed plate and the displacement plate are arranged opposite to each other and a clamping groove is formed between the two for partial placement of semi-finished brake pads, two positioning shafts are erected on the rotating shaft, the two positioning shafts are arranged opposite to each other, the displacement plate is provided with a through hole for the positioning shaft to pass through, and the two positioning shafts are provided with an electric push rod, the output end of the electric push rod is connected to the top wall of the displacement plate, and the rotating shaft is arranged near the flipping area.

[0015] The advantages of adopting the above technical solution are: when the brake pad that needs to be flipped enters the flipping part position, the brake pad moves with the transmission belt, so that the brake pad is partially placed in the clamping groove. At this time, the electric push rod starts and drives the displacement plate to move so that the displacement plate and the fixed plate combination form a clamping limit for the brake pad, and then the servo motor starts and drives the rotating shaft to rotate axially so that the brake pad swings along the axial direction of the rotating shaft, so that the brake pad flips, that is, the processing surface of the brake pad changes from a downward state to an upward state. After being flipped, the brake pad is partially located at the feed port or transportation port of the next process. At this time, the electric push rod starts in the opposite direction to move the displacement plate upward, that is, the clamping groove expands so that the displacement plate and the fixed plate combination no longer clamp the brake pad, so that the brake pad can fall into the feed port or transportation port; the above-mentioned technical setting is used to realize the flipping of the brake pad, thereby ensuring that the processing surface of the brake pad faces upward, and then ensuring that the brake pad entering the next process is processed with its processing surface facing upward, thereby improving processing accuracy and processing efficiency.
