[0065] The following will be described in more detail with reference to the schematic diagram of the automatic assembly line and assembly method of the new energy vehicle drive motor core of the present invention, wherein the preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein, while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0066] like Figures 1 to 16 The automatic assembly line of the iron core of the new energy vehicle driving motor includes: a loading and transferring mechanism 10, a gluing mechanism 20, a visual inspection mechanism 30, a stacking mechanism 40, a pressing mechanism 50, a pressure holding and curing mechanism 60, a height detection mechanism 70, a coaxiality detection mechanism 80, a laser coding mechanism 90 and a stacking offline mechanism 100 and other main parts.

[0067] like Figure 1 As shown, the loading and transferring mechanism 10 includes:

[0068] The conveyor belt 101 is used to convey the iron core material. It is placed above the tray 102. The tray 102 can move along the first conveyor line.

[0069] The first tray 102 is used to receive the iron core material on the conveyor belt 101. It is placed at the output end of the conveyor belt 101. A plurality of rows of positioning sleeves 103 are arranged on the tray. Each row of positioning sleeves 103 is parallel to the transmission direction of the conveyor belt 101 and is located below the conveyor belt 101.

[0070] A No. 1 servo transfer robot 107 is used to transfer the iron core material on the tray 102 to the material transport tool 106 at one time, and its output end is connected to a No. 1 four-claw suction cup device 105 and a visual camera 104;

[0071] The first four-claw suction cup device 105 includes four suction cup servo cylinders and a suction cup connected to the output end of each servo cylinder. The suction cup servo cylinder is installed on the first servo transfer manipulator 107.

[0072] The material transport tooling plate 106 is placed on the double-speed chain (No. 2 conveyor line body).

[0073] The output end of the first servo transfer robot 107 refers to a base that moves with the driving mechanism, such as Figure 1 shown.

[0074] The tray 102 includes a tray body, which is disposed on a Y-direction moving component. The Y-direction moving component can move along the X-direction along with the first conveyor line.

[0075] Working principle of loading and transferring mechanism 10:

[0076] 1. Punching out: The core material is punched out by a punch press and falls onto the conveyor belt 101 for transportation.

[0077] 2. Transport to the pallet tooling: The core material falls to the No. 1 pallet 102 through the movement of the conveyor belt 101, and then is transported to the set pallet tooling position;

[0078] Among them, the No. 1 tray 102 can move in two directions, X direction (moving direction of the No. 1 conveyor line body) and Y direction, in the plane, so that each positioning sleeve can bear an iron core material.

[0079] 3. Photo positioning: The visual camera 104 collects the position image of the core material and transmits the image data to the control system for processing to ensure the accurate position of the core material. That is, to avoid the movement error of the Y-axis moving component and the No. 1 conveyor line, and ensure that the core material is located directly below the corresponding visual camera 104.

[0080] 4. Grasping and transferring: The No. 1 four-claw suction cup device 105 grabs the core material through the No. 1 servo transfer manipulator 107 and places it on the material transport tooling plate 106. That is, the control system instructs the four-claw suction cup device 105 to accurately grasp according to the position data fed back by the visual camera 104.

[0081] like Figure 1 As shown, taking a No. 1 servo transfer robot 107 as an example, two workstations of a No. 1 four-claw suction cup device 105 are shown.

[0082] The No. 1 four-claw suction cup device 105 firmly grasps the iron core material through the vacuum adsorption device, and the No. 1 servo transfer robot 107 drives the four-claw suction cup device 105 to transfer the grasped iron core material to the material transport tooling plate 106 for subsequent processing.

[0083] 5. Waste processing: If the core material is unqualified, the No. 1 four-claw suction cup device 105 moves it to the corresponding waste frame 108.

[0084] The control system detects the core material at the middle receiving position on the No. 1 conveyor line. If it is detected that the core material is defective or does not meet the requirements, the four-claw suction cup device 105 is instructed to transfer the unqualified core material to the waste frame 108 for waste disposal.

[0085] In this embodiment, the first conveying line body, the second conveying line body and the third conveying line body are all double-layer line bodies. Fig.13 shown.

[0086] A Z-direction moving mechanism is respectively arranged between the output end of the upper layer wire body and the input end of the lower layer wire body, and between the input end of the upper layer wire body and the output end of the lower layer wire body.

[0087] Specifically, Figure 1 As shown, the punch press discharges materials according to the set number of punches, and the core materials fall onto the feeding conveyor line and are transported to the fixed station via the conveyor line;

[0088] Two sets of No. 1 pallets are preset at the fixed workstation. Each set of No. 1 pallets contains four positioning sleeves in a 2×2 layout. After the positioning sleeves reach the predetermined position, they receive the iron core materials conveyed by the belt line.

[0089] The left and right No. 1 pallets are moved and used alternately to ensure that the equipment continues to work without stopping; a counting infrared sensor is fixed at the end of the belt line to count the iron core materials received by the positioning sleeve.

[0090] When the positioning sleeve is filled with core material, the mechanism moves the positioning sleeve from the middle material receiving position to the left and right material loading positions;

[0091] Before loading, the visual camera takes a picture of the core material for positioning. The four-claw suction cup mechanism is equipped with a servo mechanism to adjust the position and angle of the core material. The four-claw suction cup mechanism simultaneously grabs four pieces of core material and transfers them to the material transport tooling plate 106. The tray is equipped with a positioning tooling to fix the core material, such as Fig.14 shown.

[0092] Gluing mechanism 20, such as Figure 2 As shown, it includes a frame protection cover 201, a three-coordinate translation platform 203 is installed in the frame protection cover 201, and drives the gluing system 202 to perform gluing.

[0093] The three-coordinate translation stage 203 has three degrees of freedom in XYZ directions.

[0094] The glue coating head of the glue coating system 202 includes a plurality of nozzles, and the opening and closing of the nozzles are controlled by a control system to achieve accurate glue coating on different parts of the iron core.

[0095] Working principle of the gluing mechanism 20:

[0096] 1. Arrival of the material transport tooling plate 106: The material transport tooling plate 106 reaches the designated position of the glue coating mechanism 20 through the conveying system (conveying line No. 2), and the cylinder (such as Figures 11-12 As shown in the figure), the material transport tooling plate 106 stays at the specified position, and the system reads the information on the material transport tooling plate 106.

[0097] like Figures 11-12 : The output shaft of the stop cylinder is connected to a stop groove, and one end of a stop block is hinged in the stop groove. Under the action of the tooling plate, when the lower end surface of the stop block contacts the stop groove, the tooling plate stops.

[0098] After the stop cylinder retracts, release the tooling plate. Fig.12 The middle arrow indicates the running direction of the tooling plate.

[0099] 2. Lifting of the material transport tooling plate 106: After the material transport tooling plate 106 is lifted, the gluing mechanism 20 applies the glue through the contour tooling, and the lifting mechanism lifts the material transport tooling plate 106 to the gluing position to ensure that the gluing head 202 can accurately apply the glue.

[0100] 3. Gluing operation: The gluing system 202 controls the glue coating amount and glue coating position according to the instructions of the control system to ensure that the four iron cores in the material transport tooling plate 106 are glued each time. The gluing head of the gluing system 202 evenly coats the glue on the surface of each iron core according to the set glue coating amount and glue coating position.

[0101] 4. Beat control: Complete the operation of one material transport tooling plate 106 entering and exiting the equipment every 8 seconds. After the gluing is completed, the cylinder is stopped and released. The gluing process is controlled to be completed within 8 seconds to ensure that the iron core of each tray is evenly glued before being released to enter the next process.

[0102] Among them, for core materials of different sizes, how to apply glue evenly according to the set glue coating amount and glue coating position, and avoid glue shortage or glue overflow, the technical solutions involved are as follows:

[0103] Step 1: The transport tooling plate arrives at the designated location

[0104] After the material transport tooling plate 106 is transported to the designated position of the gluing mechanism 20 through the conveying system (such as the second conveyor line), the stop cylinder is actuated to ensure that the tooling plate stays at the correct position. At this time, the gluing system will read the information on the tooling plate 106 to ensure that the subsequent operation can be adjusted according to the mark on the tooling plate to adapt to different core sizes.

[0105] Step 2: Lift the tooling board to the gluing position

[0106] The material handling tooling plate 106 is lifted to the designated gluing position by the lifting mechanism. During this process, the lifting height is ensured to be accurate to avoid the glue coating head 202 failing to properly cover the surface of the core due to unstable lifting. The lifting mechanism may include precise sensors or limit switches to ensure that each lifting reaches the same height.

[0107] Step 3: Gluing operation

[0108] The glue coating system 202 accurately controls the flow and position of the glue through the glue coating head 202 according to the instructions of the control system. In order to prevent glue shortage or overflow, the glue coating system may be equipped with a flow sensor and a pressure control mechanism. Specifically, the glue coating head 202 can control the glue coating amount and glue coating accuracy in a variety of ways:

[0109] Flow control: The flow sensor in the glue coating head detects the flow of glue in real time to ensure a stable and uniform amount of glue, avoiding too much or too little glue.

[0110] Spraying mode: The glue coating head can be set to different spraying modes (such as spot or line) to adapt to different shapes of cores.

[0111] Precise positioning: The control system of the glue coating head ensures the accurate position of the glue coating head through feedback control. The iron cores of different sizes automatically adjust the working path of the spray head and the opening size of the nozzle according to the pre-set settings.

[0112] Step 4: Apply glue evenly

[0113] The glue coating system 202 evenly coats the surface of the core according to the set glue coating amount and glue coating position. In order to avoid glue shortage and glue overflow, the following optimization methods can be used:

[0114] Dynamically adjust nozzle speed: During the gluing process, the movement speed of the spray head is automatically adjusted according to sensor feedback to ensure that the amount of glue applied meets the requirements.

[0115] Multi-point glue coating control: For cores of different sizes, the system can control the glue spraying at different points so that the surface of each core can be evenly covered.

[0116] Step 5: Inspection and feedback after gluing

[0117] After the glue coating is completed, the glue coating system 202 can check the quality and uniformity of the glue coating through a detection device (such as image recognition technology or photoelectric sensor). If the glue coating is found to be uneven or there is a lack of glue or overflow of glue, the system will automatically adjust the parameters and re-perform the glue coating operation to ensure the glue coating quality of each iron core.

[0118] Step 6: Beat Control and Release

[0119] After the gluing is completed, the stop cylinder releases the material transport tooling plate 106 to enter the next process. The time control of the entire gluing process is very important to ensure that the operation time of each tooling plate is completed within 8 seconds, thereby ensuring the stability of the production rhythm.

[0120] Step 7: Adjustment for different core sizes

[0121] For cores of different sizes, the glue coating position, spraying path, flow rate, etc. of the glue coating head 202 can be automatically adjusted according to the system settings. These adjustments can be achieved in the following ways:

[0122] Size sensing: Use vision systems or sensors to identify the size of the core and adjust the position of the glue head and the amount of spray.

[0123] Software control: The control system can automatically adjust the glue coating mode, nozzle size and spray path according to the set core size, so as to ensure the appropriate amount of glue and avoid glue shortage or overflow.

[0124] Visual inspection mechanism 30 such as Figure 3 As shown, including:

[0125] Visual mechanism base 301;

[0126] The camera 302 is used to collect the image of the iron core material after the glue is applied, and is installed on the camera installation device 303. The camera installation device 303 is connected to the visual mechanism base 301 through the camera height adjustment device 306;

[0127] The first rotating lifting platform 305 is placed below the second conveyor line body.

[0128] Among them, in order to ensure that the camera 302 is directly above the corresponding core material, when the material transport tooling plate 106 runs to the inspection station, it is lifted and rotated 90 degrees under the action of the No. 1 rotating lifting platform 305, and then the camera 302 performs image acquisition.

[0129] After rotating 90 degrees, each camera 302 is directly above the corresponding core material.

[0130] Working principle of the visual inspection mechanism 30:

[0131] 1. Arrival of the material transport tooling plate 106: The material transport tooling plate 106 reaches the specified position of the visual inspection mechanism 30 through the conveying system, the blocking cylinder works, so that the pallet stays at the specified position, and the system reads the information on the material transport tooling plate 106.

[0132] 2. Image acquisition: The camera 302 acquires images of the glue-coated area of ​​the glue-coated iron core material under the uniform illumination of the light source 305 to ensure the clarity and accuracy of the image.

[0133] 3. Image processing: The image processing system processes the image collected by the camera 302, analyzes whether the glue coating is uniform, whether there is glue shortage or glue overflow, and outputs the test results. By comparison, if the glue coating effect is qualified, the iron core is released. The cycle of this station is 6 seconds.

[0134] Specifically, the specific steps involved in analyzing whether the glue coating is uniform, whether there is glue shortage or glue overflow are as follows:

[0135] Step 1: Preprocessing before image acquisition

[0136] Before the camera 302 captures the image, it is necessary to first ensure that the illumination of the light source 305 is uniform and sufficient. The choice of light source can affect the contrast and clarity of the image, so it is necessary to adjust the angle and intensity of the light source to eliminate shadows and reflections and ensure that the glue-coated area captured is clear. This step may also include automatically adjusting the focus of the camera to ensure that the captured image has sufficient resolution.

[0137] Step 2: Image acquisition and data transmission

[0138] The camera 302 collects images of the glue-coated area on the surface of the core. When collecting images, the camera should be accurately aligned according to the glue-coated area on the surface of the core to ensure that each area is captured. The collected data will be transmitted to the image processing system for subsequent analysis.

[0139] Step 3: Image preprocessing and enhancement

[0140] The original image collected may have problems such as noise and uneven lighting, so image preprocessing is required. Common preprocessing techniques include:

[0141] Denoising: Use filtering algorithms (such as median filtering) to remove image noise.

[0142] Grayscale transformation: grayscale the image to make the glued area more contrasted with the background, making it easier to analyze later.

[0143] Edge detection: Use edge detection algorithms (such as Canny edge detection) to extract the boundaries of the glued area for subsequent analysis.

[0144] Step 4: Glue coating quality analysis

[0145] In the image processing stage, the system determines whether the glue coating is uniform through comparative analysis. The specific operations are as follows:

[0146] Uniformity analysis: Divide the image into regions and calculate the average grayscale value of each region. By comparing with the preset standard value, the uniformity of glue coating can be judged. If the grayscale value of some regions is lower than the set threshold, it indicates that there may be a lack of glue; if the grayscale value of some regions is higher than the set threshold, it indicates that there may be glue overflow.

[0147] Glue shortage detection: By calculating the glue thickness of each area in the image (reflected by the grayscale value of the image), if the grayscale value of some areas is lower than the normal range, the system determines that there is glue shortage and outputs a glue shortage warning.

[0148] Glue overflow detection: Similarly, if the grayscale value of the glue-coated area is too high, the system will detect that the glue covers more than the predetermined area and judge it as glue overflow.

[0149] Step 5: Qualification of glue coating effect

[0150] The image processing system compares the test results according to the set glue coating standards (such as glue coating uniformity, glue coating coverage, glue thickness, etc.). If the glue coating effect in the image meets the standard (uniform and no glue shortage or glue overflow), it is judged as qualified and the core can be released through the visual inspection mechanism. If glue shortage or glue overflow is detected, the system will mark it as unqualified and will not allow release.

[0151] Step 6: Test result feedback and decision making

[0152] The image processing system will pass the test results to the control system. If the glue coating effect is qualified, the system will instruct the stop cylinder to release the tooling plate and enter the next process. If it is unqualified, the alarm system or visual display will prompt the operator to perform manual inspection or adjustment.

[0153] Step 7: Beat Control

[0154] The time of each inspection process is controlled within 6 seconds, ensuring that the inspection speed of the visual inspection mechanism can match the production rhythm and improve overall production efficiency.

[0155] The stacking mechanism 40, such as Figure 4 As shown, including:

[0156] The second servo transfer robot 401 is used to transfer the iron core material on the second conveyor line body to the second pallet on the third conveyor line body; the structure of the second pallet is the same as that of the first pallet 102;

[0157] The second four-claw suction cup device 403 is connected to the output end of the second servo transfer robot 401;

[0158] The first lifting platform 402 is arranged on the third conveying line and is located below the stacking station.

[0159] A waste box 404 is provided on one side of the No. 2 conveyor line body.

[0160] Working principle of stacking mechanism 40:

[0161] 1. Lifting of the No. 2 pallet on the No. 3 conveyor line: After the No. 2 pallet is in place, the No. 1 lifting platform 402 lifts the pallet to the stacking position to ensure that the No. 2 stacking four-claw suction cup 403 can accurately place the core material. The "core material" is in sheet form, such as Fig.14 shown.

[0162] 2. Material collection and stacking: The No. 2 four-claw suction cup 403 collects materials from the material transport tooling plate 106 and performs stacking operations in sequence.

[0163] That is, the control system instructs the No. 2 four-claw suction cup 403 to grab the iron cores from the material transport tooling plate 106 and stack them in a set order to ensure that the iron cores are stacked neatly.

[0164] 3. Double-station stacking: The main line (No. 2 conveyor line body) puts four iron cores into the stacking tooling at one time, and at the same time, the branch line (another No. 2 conveyor line body) puts four iron cores into the stacking tooling in turn, putting in a total of 432 iron cores, and the last piece does not need to be coated with glue.

[0165] like Figure 4 As shown, taking a No. 2 servo transfer robot 401 as an example, two workstations of a No. 2 four-claw suction cup device 403 are shown.

[0166] Pressing mechanism 50, such as Figure 5 As shown, including:

[0167] The press-fitting servo cylinder 505 is installed on the press-fitting frame 506, and the press-fitting frame 506 is arranged on the press-fitting base 501;

[0168] The pressing head 503 is connected to the output shaft of the press-fitting servo cylinder 505;

[0169] The pressure sensor 504 is arranged on the output shaft of the press-fit servo cylinder 505;

[0170] The second lifting platform 502 is located below the pressing station of the third conveyor line.

[0171] Working principle of the press-fitting mechanism 50:

[0172] 1. Lifting of the No. 2 pallet: After the No. 2 pallet is in place, the No. 2 lifting platform 502 lifts the No. 2 pallet to the pressing position to ensure that the stacking press head 503 can press the iron core.

[0173] 2. Compacting operation: The control system instructs the pressing head 503 to compact the iron core formed after stacking to ensure that the layers of the iron core are tightly combined.

[0174] 3. Parameter control: The control system controls the pressing force and pressing time of the press-fitting servo cylinder 505 through the parameters set by the pressure sensor 504 to ensure that the iron core is pressed. The pressing force and pressing time are set according to the specifications and requirements of the iron core, and the control system monitors the pressing process in real time to ensure the pressing effect.

[0175] Among them, for core materials of different sizes, the press-fitting mechanism 50 can ensure that the phenomenon of lack of glue or overflow of glue is avoided, and the technical solutions involved are as follows:

[0176] Step 1: Pallet No. 2 is in place and lifted

[0177] After the No. 2 pallet arrives at the working position of the press-fitting mechanism 50 through the conveying system, the No. 2 lifting platform 502 starts working to lift the pallet to the press-fitting position. In this process, it is crucial to ensure that the pallet is in a precise positioning position. In order to avoid misalignment of the pallet due to cores of different sizes, the press-fitting system can be equipped with a positioning sensor to automatically adjust the alignment angle and position of the pallet. In this way, it is ensured that all cores to be press-fitted can accurately enter the press-fitting area.

[0178] Step 2: Preparation and inspection before pressing

[0179] Before press-fitting, the control system will check the glue coating status. By linking with the visual inspection mechanism 30, the system can confirm whether the glue coating of each core is uniform, without glue shortage or glue overflow. If the visual inspection finds glue coating problems, the press-fitting operation will be automatically paused or postponed until the qualified glue coating status is confirmed. This step can be achieved by sharing data with the visual inspection system through the interface to ensure that the surface status of the core meets the requirements before starting press-fitting.

[0180] Step 3: Pressing operation

[0181] After the lifting platform 502 lifts the No. 2 tray to the press-fitting position, the press head 503 presses the stacked iron cores. At this time, the control system automatically adjusts the downward pressure and stroke of the press head according to the size of the iron core and the stacking thickness. The purpose of press-fitting is to ensure that the layers of the iron core can be tightly combined, but the force must also be controlled to prevent excessive pressing from causing the glue layer to be damaged or lost, resulting in glue overflow or uneven crimping.

[0182] Step 4: Parameter control of pressing force and pressing time

[0183] The control system monitors the pressure during the press-fitting process in real time through the pressure sensor 504 to ensure that the press-fitting force is suitable for the size and specifications of the core. Specifically, the system automatically adjusts the action of the servo cylinder 505 according to the preset pressure curve according to the cores of different sizes and shapes:

[0184] Pressure setting: According to the material characteristics of the core and the requirements of the glue coating, set the appropriate press-fitting pressure to ensure that the glue coating is not pressed out or damaged. For thinner cores or thinner glue coatings, the system will reduce the pressure; for thicker cores or scenarios that require a higher degree of bonding, the pressure will increase accordingly.

[0185] Pressing time setting: The control system will also set the appropriate pressing time according to the size of the iron core and the thickness of the glue coating to ensure that the pressing process will not be too fast, so as to avoid the iron core loosening due to too short pressing time; at the same time, too long pressing time will also cause glue overflow. Therefore, precise control of the pressing time is the key to avoid glue overflow.

[0186] Step 5: Real-time monitoring and feedback adjustment

[0187] During the press-fitting process, the control system adjusts the press-fitting force and time during the press-fitting process through real-time data feedback from the pressure sensor 504. Through the PID control algorithm (proportional-integral-differential control), the control system can automatically adjust the pressure of the servo cylinder to ensure the stable quality of each press-fitting and avoid problems such as lack of glue and overflow of glue. If any abnormality is detected during the press-fitting process (such as excessive or insufficient pressure), the system will stop immediately and send an alarm signal to prompt the operator to check and adjust the process parameters.

[0188] Step 6: Automatic adjustment for cores of different sizes

[0189] The press-fitting mechanism 50 automatically adjusts the pressure of the press head and the press-fitting time to adapt to different specifications of core materials of different sizes. For example, for large-sized cores, the press-fitting force can be appropriately increased, while for small-sized cores, the press-fitting force needs to be appropriately reduced. The system will obtain data from the visual inspection system based on the size information of the core, and automatically adjust it in combination with the set press-fitting parameters to ensure that the press-fitting operation always meets the process requirements.

[0190] Step 7: Inspection and quality control after pressing

[0191] After the press-fitting operation is completed, the quality control system of the press-fitting mechanism 50 will perform a post-press-fitting inspection to confirm the pressing effect of the core. Common inspection methods include:

[0192] Core stability test: Use mechanical sensors or displacement sensors to detect the stability of the core after press-fitting. If the core is loose, it means that the press-fitting force is insufficient, and the system will readjust the parameters and press-fit again.

[0193] Glue quality inspection: After pressing, you can also use infrared sensors or other detection equipment to check whether the glue coating is still uniform to ensure that the glue is not over-extruded or lost during the pressing process.

[0194] Step 8: Qualification and release

[0195] After the press-fitting is completed, the control system will automatically determine the press-fitting result. If the test is qualified, the core will be released to the next process; if it is unqualified (such as loose press-fitting or glue coating problems), the operator will be prompted through an alarm or display screen to intervene manually or readjust the press-fitting parameters.

[0196] The pressure-maintaining and curing mechanism 60 is located on one side of the No. 3 conveyor line. Figure 6 As shown,

[0197] Install the frame 601, on which the indexing table 609 is rotatably arranged;

[0198] The curing frame 605 and the blower 607 are arranged in sequence along the rotation direction of the indexing plate 609;

[0199] The curing tool 603 can move along the Z direction and is connected to the lifting plate of the lifting device; the bottom surface of the curing tool 603 is open;

[0200] A heating coil 604 is located in the curing tooling 603 and connected to a lifting plate of the lifting device;

[0201] The curing plate 606 is arranged on the curing frame 605 through a cylinder;

[0202] The blower 607 is connected to the air duct 608 .

[0203] The heating coil 604 is connected to an external power supply system.

[0204] Working principle of the pressure-maintaining and curing mechanism 60:

[0205] 1. Lifting of the No. 2 pallet: After the No. 2 pallet is in place, the lifting mechanism positions and lifts the No. 2 pallet, and the servo transfer robot grabs the iron core and places it on the indexing table 609. The indexing table rotates to transport the materials to the designated positions.

[0206] 2. Heating under pressure: Through the rotation of the indexing plate 609 and the downward movement of the heating coil 604, the iron core enters the heating coil 604, and the curing press plate 606 is pressed onto the iron core.

[0207] The temperature of the iron core is displayed by the temperature sensor 602 , and the iron core is cured and shaped in the curing tool 603 .

[0208] 3. Cooling and shaping: The iron core after pressure-maintaining heating is sent to the cooling device, and the temperature of the iron core is quickly cooled by the cold air blown by the blower 607 through the air duct 608 connected thereto.

[0209] 4. Transplanting operation: The material detection sensor 610 detects the iron core and controls the gripper A of the transplanting mechanism through the control system to grab the iron core to be cured and put it into the curing station. At the same time, the gripper B takes out the cured iron core and puts it back on the No. 2 tray on the No. 3 conveyor line.

[0210] 5. Curing process: The iron core to be cured is placed in the station on the indexing table 609, and the cured iron core is placed back on the No. 2 tray on the No. 3 conveyor line. The iron core enters the curing and cooling stations in turn. The iron core needs to be pressurized during heating and curing.

[0211] Height detection mechanism 70, such as Figure 7 As shown, including:

[0212] A height detection frame 705 is arranged on the height detection frame 701, and the No. 3 conveyor line passes through the height detection frame 705;

[0213] The second rotating lifting platform 702 is located below the height detection station on the third conveyor line and is fixed to the height detection frame 701;

[0214] The height servo cylinder 704 is arranged on the height detection frame 705, and its output shaft is connected to the upper detection plate; the upper detection plate is connected to the lower detection plate through a positioning rod, and a No. 1 spring is sleeved on the positioning rod. The No. 1 spring contacts the upper detection plate and the lower detection plate, and the lower detection plate is connected to the positioning ring.

[0215] like Fig.15 As shown, the height detection sensor 703 includes a laser rangefinder, a detection rod, a lower detection plate, an upper detection plate, a positioning rod, a positioning ring, a No. 1 spring and a No. 2 spring.

[0216] The laser rangefinder fixes the lower detection plate, the detection rod is clamped on the positioning sleeve, the positioning sleeve is fixed on the upper detection plate, and the positioning sleeve and the upper detection plate are connected through a No. 2 spring.

[0217] The stroke of the height servo cylinder 704 is a fixed value. When the core height is equal to the set standard height, the positioning ring and the upper end surface of the core are against each other. At this time, the Z-direction distance between the laser rangefinder and the detection rod is a certain value, the No. 1 spring is not deformed, and is in contact with the upper detection plate and the lower detection plate.

[0218] The height detection sensor includes a laser rangefinder and a data processing module. The laser rangefinder is used to measure the height of the iron core, and the data processing module is used to process the measurement data and output the detection result.

[0219] 2. Data processing: The height sensor 703 collects the core height data, processes it through the control system, and outputs the detection results. The control system processes the height detection mechanism 70 collected by the height sensor 703. The working principle is:

[0220] 1. Height detection: The solidified iron core is transported from the cooling station to the height detection mechanism 70 , and the second rotating lifting platform 702 sends the iron core to the height sensor 703 under the action of the second rotating lifting platform 702 to accurately measure the height of the iron core.

[0221] Specifically, initially, the upper end surface of the positioning rod is clamped on the upper detection plate, that is, at this time, the Z-direction distance between the upper detection plate and the lower detection plate is the largest, and at this time, the No. 1 spring is in a natural state, that is, there is no deformation.

[0222] After the core is lifted, the height servo cylinder 704 moves downward along the Z direction until the positioning ring and the upper end surface of the core are in contact.

[0223] At this time, if the core height is greater than the set standard height, since the stroke of the height servo cylinder 704 is a fixed value, after the positioning ring and the upper end surface of the core are against each other, the lower detection plate remains stationary, the No. 1 spring is compressed and deformed, and the Z-direction distance between the detection rod and the laser rangefinder changes.

[0224] If the core height is less than the set standard height:

[0225] When the height of the core is lower than the set standard height, the compressed spring (such as spring No. 1) will be in a natural state, indicating that it has no deformation. At this time, the Z-direction distance between the positioning rod and the laser rangefinder remains unchanged, and the upper end surface of the core does not contact the lower detection plate. Therefore, the detection system determines the height of the core by comparing the difference between the measured Z-direction distance and the set standard height.

[0226] The specific process of height detection:

[0227] Positioning and initial state:

[0228] After being processed in the cooling station, the iron core is transported to the height detection mechanism 70 by the second rotating lifting platform 702. In this process, the second rotating lifting platform 702 lifts the iron core to the positioning position to ensure that the upper end surface of the iron core is aligned with the measurement area.

[0229] Initially, the upper end face of the positioning rod is clamped on the upper detection plate to ensure that the Z-direction distance between the upper detection plate and the lower detection plate is the largest, so that the No. 1 spring is in a natural state and is not compressed. At this time, the initial state of the entire height detection system is zero.

[0230] Core lifting and height measurement:

[0231] When the core is lifted, the height servo cylinder 704 moves along the Z direction, pushing the core downward until the height servo cylinder 704 stops moving. At this time, the system starts to perform actual height detection to measure the actual height of the core.

[0232] Height judgment and spring deformation:

[0233] If the core height is greater than the set standard height:

[0234] If the actual height of the core is greater than the set standard height, the lower detection plate remains fixed. When the upper end surface of the core contacts the positioning ring, the No. 1 spring is compressed, resulting in deformation.

[0235] The laser rangefinder senses the compression of the No. 1 spring by measuring the change in the Z-direction distance between the positioning rod and the detection plate in real time, and feeds this data back to the control system. Based on the degree of compression, the system determines that the height of the core exceeds the set standard.

[0236] If the core height is less than the set standard height:

[0237] If the height of the iron core is lower than the set standard height, since the position of the lower detection plate does not change, the No. 1 spring is not compressed. At this time, the Z-direction distance between the positioning rod and the laser rangefinder will not change.

[0238] Since no deformation occurred, the difference between the Z-distance measured by the laser distance meter and the standard distance showed that the core height was insufficient.

[0239] Calculation and output of height deviation:

[0240] Super-height detection: The control system calculates the actual height of the core based on the difference between the measured Z-direction distance and the set standard height. If the actual height exceeds the set standard, it is judged as super-height and a corresponding alarm signal or mark is generated.

[0241] Insufficient height detection: If the measurement result shows that the core height is lower than the set standard, the system will also calculate the insufficient height value based on the change in Z-direction distance and generate an alarm or prompt.

[0242] Feedback and adjustment: During the inspection process, the control system will analyze the data in real time based on the measurement results. If the height of the core is unqualified, the system will stop the transmission of the core or enter the correction program for manual processing or adjustment.

[0243] Qualification and release: For cores that meet the standards, the inspection system will confirm that they are qualified and release them to the next process through control signals for subsequent processing. At this time, the cores will continue to be transported forward along the production line.

[0244] From above:

[0245] Dynamic height measurement: The height detection mechanism 70 uses a precise laser rangefinder and a positioning rod, combined with the deformation of the No. 1 spring, to measure the height of the iron core in real time to determine whether it meets the set standard.

[0246] Automatic adjustment and feedback: The system automatically determines the height deviation of the core based on the measurement results and outputs qualified or unqualified test results. For unqualified cores, the system will provide timely feedback to ensure that the product quality on the production line meets the requirements. The data is processed to determine whether the height of the core meets the set standards and output the test results. Qualified cores enter the next process.

[0250] The servo cylinder 804 is arranged on the coaxiality detection frame 801, and a coaxiality detection sensor 803 is arranged on its output shaft.

[0251] The coaxiality detection sensor 803 has the same structure and principle as the height detection sensor 703 .

[0252] Here, "coaxiality" means that the upper end faces of all cores belong to the same plane.

[0253] The coaxiality sensor includes a displacement sensor and a data processing module. The displacement sensor is used to measure the coaxiality of the iron core, and the data processing module is used to process the measurement data and output the detection results.

[0254] Working principle of coaxiality detection mechanism 80: 1. Coaxiality detection: The solidified iron core is transported to the coaxiality detection mechanism 80 by the height detection station of the No. 3 conveyor line. The No. 3 rotating lifting platform 802, under the action of the servo cylinder 804, sends the iron core to the coaxiality sensor 803 to accurately measure the coaxiality of the iron core. 2. Data processing: The coaxiality sensor 803 collects the coaxiality data of the iron core, processes it through the control system, and outputs the detection results. The control system processes the data collected by the coaxiality sensor 803, determines whether the coaxiality of the iron core meets the set standard, and outputs the detection results. The qualified iron core enters the next process.

[0255] Laser coding mechanism 90, such as Fig. 9 As shown, including:

[0256] The laser coder mounting frame 906 is arranged on the mounting base frame 901, and the No. 3 conveyor line body passes through the mounting base frame 901;

[0257] The third rotating lifting platform 902 is located below the coding station on the third conveyor line and is fixed to the mounting base frame 901;

[0258] The laser coder installation device 905 is arranged on the laser coder installation frame 906, on which the laser coder 904 is arranged.

[0259] Working principle of laser coding mechanism 90: 1. Laser coding: The qualified iron core is transported from the coaxiality detection station of the No. 3 conveyor line to the laser coding mechanism 90. The No. 3 rotating lifting platform 902 (i.e., the No. 2 tray) delivers the tooling plate 903 with the iron core to the laser 904 and performs laser coding on the surface of the iron core to ensure that the coding content is clear and the position is accurate. 2. Coding operation: The laser 904 controls the coding content and coding position according to the instructions of the control system to complete the coding operation. The control system instructs the laser 904 to perform the coding operation according to the set coding content and position to ensure that the coding content of each iron core is consistent and the position is accurate.

[0260] The stacking downline mechanism 100 is located on one side of the No. 3 conveyor line body. Fig.10 As shown, including:

[0261] Palletizing rack 1001;

[0262] The offline conveyor belt 1002 is arranged on the stacking rack 1001;

[0263] The transfer clamp 1003 is used to transfer the iron core on the No. 3 conveyor line to the offline conveyor belt 1002. It is located above the offline conveyor belt 1002 and is set on the servo transfer rack 1004;

[0264] like Fig.10 As shown, the servo transfer rack 1004 shows two workstations of the transfer clamp 1003.

[0265] Working principle of the palletizing off-line mechanism 100: 1. Palletizing operation: The iron cores after coding are transported from the laser coding mechanism 90 to the palletizing off-line mechanism 100, and the transfer clamp 1003 grabs the iron cores and stacks them on the stacking rack 1001. 2. Off-line operation: The palletized iron cores are processed off-line through the conveyor belt 1002. After the transfer clamp 1003 completes the palletizing of the iron cores in the set order, the off-line conveyor belt 1002 transports the palletized iron cores to the off-line station for final off-line processing.
