Description

Technical Field

[0001] The present invention relates to the technical field of a continuous machine, and in particular to a novel turning station of a continuous machine and a method for high-efficiency operation thereof. Background Art

[0002] In the production of SMT electronic components, the equipment that combines the production processes of testing, marking, visual inspection, and taping is called a one-stop machine (TMTT). In the case of huge demand for SMT electronic components, the production capacity of a one-stop machine is often used as an important indicator to measure the performance of the equipment, and the production capacity is closely related to the speed of the coordinated action of the equipment components.

[0003] The existing steering station components of a consistent machine include: a cylinder (adjustable stroke, a cam divider component, a stepper motor (steering), and a nozzle component. Its main actions are: (1) the cylinder returns, and the nozzle component with the material descends to the specified position and height; (2) the steering motor rotates a step angle to adjust the position of the product; (3) the cylinder pushes, and the nozzle component with the material rises to the specified position; (4) the cam divider rotates to enter the next station.

[0004] However, the conventional machine has the following defects in the turning station: (1) The cam divider is an intermittent transmission element, and its dynamic-static ratio is fixed (the positioning time and the static time are fixed). It is determined during the selection and design. After use, the action time cannot be changed. Therefore, the time cannot be adjusted according to the time consumed by different stations. Different components have different detection times, and the time consumed at the corresponding stations is different. Therefore, the existing conventional machine cannot be used for the detection of different components; (2) The speed of the stepper motor is 120-600R / MIN, and the acceleration time is 2 (3) There is no angle compensation in the steering station, which is usually 180 degrees forward and then 180 degrees reverse, which often causes the material to not be turned in place, resulting in errors in subsequent station detection and marking, and even misjudgment, affecting the product's pass rate; (4) The existing material troughs are all fixed fixtures of the corresponding material shape milled out at one time, which can only be applied to one type of material, reducing the versatility of the material detection package and the detection capability of the equipment.

[0015] Preferably, a positioning substrate is fixedly mounted on the second optoelectronic mounting board, the positioning substrate is located on the right side of the positioning groove and is parallel to the extension direction of the guide groove in the initial state, and the head end of the positioning substrate is located directly above the right side edge of the bottom surface of the U-shaped groove.

[0016] Preferably, the head end of the positioning substrate is F-shaped and includes two limit plates with the same structure, and the two limit plates are respectively located on both sides of the positioning component on the right side of the U-shaped groove.

[0017] A novel method for high-efficiency operation of a turning station of a continuous machine includes the following steps:

[0018] S1: Set the dynamic-static ratio of the drive motor, i.e., the DD motor, according to different detection components, so as to complete the detection action of each workstation in the shortest time;

[0019] S2: After the previous station completes the corresponding work, the driving motor rotates a step angle to rotate the nozzle assembly to the top of the steering station assembly;

[0020] S3: The nozzle motor rotates to drive the nozzle assembly to bring the material down, and the consumption time is T1;

[0021] S4: The steering motor drives the steering seat of the steering station assembly to rotate forward by a step angle, the step angle range is 180-185 degrees, and the consuming time is T2;

[0022] S5: The nozzle motor reverses, and the nozzle assembly rises with the material, and the time consumed is T3;

[0023] S6: while S5 is being performed, the steering motor drives the steering seat to reverse by 0-5 degrees to compensate for the extra rotation angle in step S4, thereby completing the resetting of the steering seat. The time consumed at this time is T4;

[0024] S7: During the execution of S5, the driving motor waits for other stations to meet their starting conditions. When the suction nozzles of other stations are all raised, the driving motor drives the suction nozzle assembly to move to the next station. During this process, the suction nozzle assembly is always in a vacuum state.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By arbitrarily setting the dynamic-static ratio of the DD motor, the optimal time interval for the rotation of the DD motor can be set according to the different time requirements of different materials, replacing the fixed dynamic-static ratio of the existing cam divider, making the beat control more flexible and reducing the use of invalid time, thereby effectively saving the equipment operation time and improving the equipment operation capacity; (2) The DD motor improves the equipment operation accuracy, making the relative position of the positioning groove of the suction nozzle assembly and the steering station assembly more accurate, and at the same time using a servo motor to drive the steering seat to rotate, the steering response time is shorter, thereby saving the overall movement time required for the steering station. ; (3) The steering seat rotates at an angle of more than 180 degrees, and the excess angle is 0-5 degrees, which can effectively compensate for the rotation angle error caused by the inconsistent rotation caused by the gap between the material and the positioning groove, so that the material rotation angle is closer to 180 degrees, realizing the compensation of the material rotation angle, improving the material steering accuracy, and facilitating the detection of subsequent workstations; (4) After the angle compensation, the steering seat is reversed and reset by 0-5 degrees, which effectively reduces the reset time of the steering station, thereby effectively reducing the time required for the entire workstation to work. (5) The setting of the U-shaped groove and the positioning component in coordination further improves the steering station's position after the material enters the positioning groove. The limitation makes the positioning more accurate. At the same time, when the steering seat rotates, the two sides of the U-shaped groove are used to cooperate with the positioning component to realize the effective rotation of the material, thereby reducing the angular error of the material rotation and improving the steering accuracy; (6) The positioning component is divided into two limit columns, which divide the open two sides of the U-shaped groove into three grids, which is convenient for positioning and limiting the pins of the material. At the same time, the positioning groove can be applied to materials of the same size but with 2-6 pins, thereby greatly improving the versatility of the equipment and effectively reducing the equipment cost; (7) The guide groove, the light and the optical fiber transceiver cooperate with each other to effectively monitor whether there is material in the positioning groove, so as to determine the rotation. Whether the steering seat is performing steering work; (8) The positioning substrate is used to be parallel to the left side of the positioning component on the right side when the steering seat rotates 180 degrees, so that when the positioning slot continues to rotate with the steering seat, the positioning substrate is used to calibrate the material, and when the material is in contact with the positioning substrate, the material stops rotating, thereby ensuring that the material rotation angle is 180 degrees, further improving the steering accuracy of the material; (9) The positioning substrate is F-shaped, which is convenient for avoiding the positioning component, further ensuring the accuracy of positioning, and can limit positioning from both ends of the material. When both ends of the material are in contact with the limit plates of the positioning substrate, the material is turned to 180 degrees, further improving the steering accuracy;(10) The method of the present invention shortens the working cycle of the entire turning station by controlling the rhythm of each step. At the same time, the turning seat only needs to perform a 0-5 turning reset, and resets synchronously after the suction nozzle assembly with the material rises, and the reset time is extremely short. Therefore, as long as the suction nozzles of other stations are also in the state of suction nozzle rising, the first turntable can rotate, and the suction nozzle can achieve the final reset during the rotation process, thereby shortening the rotation interval of the first turntable, thereby greatly shortening the operation cycle, thereby improving the equipment operation capacity. ; BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3The present invention provides a novel steering station of a consistent machine, including a transfer assembly 100 and a steering station assembly 200; the transfer assembly 100 includes a main bracket 110, a drive motor 120, a first turntable 130 and a nozzle assembly 140, the fixed end of the drive motor 120 is fixedly mounted on the main bracket 110, and the rotating shaft of the drive motor 120 is fixed to the middle of the first turntable 130; the nozzle assembly 140 is fixed to the outer edge of the first turntable 130, the nozzle assembly 140 points to the steering station assembly 200, and the drive motor 120 is a direct-driven DD motor.

[0035] The steering station assembly 200 includes a steering bracket 210, a steering motor 220 and a steering seat 230. The rotating shaft of the steering motor 220 is fixedly connected to the bottom of the steering seat 230, and the steering motor 220 is fixedly installed on the steering bracket 210. A positioning groove 240 is fixedly set on the upper surface of the steering seat 230, and the positioning groove 240 is opposite to the suction nozzle assembly 140. The steering motor 220 is a servo motor.

[0036] The transfer assembly 100 is used to drive the nozzle assembly 140 to rotate with the material, stop at different stations, inspect the material 300, drive the material 300 to run to all stations in sequence, perform corresponding actions, and then run to the next station to achieve a cycle. The steering station assembly 200 is used to adjust the direction of the material 300 that has reversed, and at the same time position the material 300, so that the subsequent stations can perform corresponding inspection and sorting on the material 300.

[0037] When the present invention is working, the suction nozzle assembly 140 sucks up the material 300 after the work of the previous station is completed and rotates with the material to the top of the steering station, the suction nozzle assembly 140 descends with the material, and then the suction nozzle assembly 140 breaks the vacuum after reaching the positioning groove 240, and the connection between the suction nozzle assembly 140 and the material 300 is lost, and then the steering motor 220 rotates to drive the material 300 to turn, thereby achieving a unified direction of the material 300. In one embodiment, the steering motor 220 uses a servo motor, which effectively improves the response performance of the steering, greatly shortens the acceleration time, thereby effectively improving the efficiency of the steering, and reducing the working cycle of the steering station assembly 200, thereby improving the overall operation and production efficiency of the equipment. It has a simple structure and is easy to install, and does not require an external encoder for position detection, which is more efficient. The DD motor has the characteristics of high precision and high responsiveness. Its repeat positioning accuracy of ±15″ exceeds the ±50″ of the cam divider. Using the DD motor to drive the first turntable 130 can effectively improve the positioning accuracy of the nozzle assembly 140 after rotating a step angle, ensuring that the nozzle assembly 140 can be aligned with the relative station within the error tolerance range, ensuring that the entire equipment operates more normally. At the same time, the DD motor can set the dynamic-static ratio arbitrarily. According to the shortest time for each station to perform the corresponding action, the longest seat is taken out to determine the waiting time for a nozzle to stop and rotate again. Therefore, according to the different detection times of different materials 300, the waiting time is also different. Therefore, the DD motor can set the dynamic-static ratio arbitrarily according to the different detection times of different materials 300, so as to maximize the use of time and complete the action in the shortest time. Compared with the fixed dynamic-static ratio of the cam divider, the DD motor rotates more flexibly and can effectively avoid the waste of time and effectively control the operation rhythm of the equipment, thereby improving the production capacity of the equipment in the same period. The DD motor has a compact structure and is easy to use. The lightweight design is simple to install and debug, which is more convenient for the installation and maintenance of the equipment. The dynamic-static ratio refers to the ratio of the time consumed by the motor rotating and pausing.

[0038] like Figure 4As shown, preferably, the nozzle assembly 140 includes a nozzle motor 141, a cam 142 and a nozzle 143. The output end of the nozzle motor 141 is fixedly connected to the cam 142, and the cam 142 and the nozzle 143 are rotatably connected. The nozzle motor 141 adopts a servo motor, which replaces the cylinder drive, so that the nozzle 143 can be accurately positioned up and down, and the height of the nozzle 143 can be set according to the specific situation. The stroke is the shortest, and the acceleration time is increased to 100 or even tens of milliseconds, which effectively saves the time of the nozzle 143 moving up and down. The specific working process of the suction nozzle assembly 140 is as follows: after the DD motor drives the suction nozzle assembly 140 to reach the top of the turning station, the system drives the suction nozzle motor 141 to rotate, and the rotation of the suction nozzle motor 141 drives the cam 142 to rotate. The cam 142 has an inclined section. As the suction nozzle motor 141 rotates, the cam 142 gradually rotates to the lowest point of the cam 142 and contacts the suction nozzle 143 and presses the suction nozzle 143 downward, so that the suction nozzle 143 drives the material 300 to be pressed down onto the positioning groove 240; when the suction nozzle 143 rises, the suction nozzle motor 141 flips, and the cam 142 contacts the suction nozzle 143 from the lowest point, and gradually rotates to the highest point and contacts the suction nozzle 143, thereby realizing the rising of the suction nozzle 143.

[0039] Preferably, the step angle of the forward rotation of the steering seat 230 driven by the steering motor 220 is 180-185 degrees, and the angle of the reverse rotation of the steering seat 230 driven by the steering motor 220 is 0-5 degrees. In the specific implementation, on the one hand, due to the installation position error of the positioning groove 240, the positioning groove 240 has an angular deviation, resulting in that when the motor drives the steering seat 230 to rotate 180 degrees, the positioning groove 240 does not rotate to 180 degrees; on the other hand, because the size of the positioning groove 240 needs to be slightly larger than the size of the material 300, so that the material 300 can be smoothly inserted into the positioning groove 240, at this time, when the steering seat 230 and the positioning groove 240 rotate together, due to inertia, the material 300 is still in the original position. As the positioning groove 240 continues to rotate, an oblique angle is formed between the top edge of the material 300 and the side edge of the positioning groove 240. Therefore, when the positioning groove 240 rotates 180 degrees, the material 300 does not rotate to 180 degrees; due to the above reasons, it is necessary to perform angle compensation on the steering station, so that the rotation angle of the material 300 can be closer to 180 degrees, thereby reducing the angle error of the steering and improving the accuracy. The present invention sets a compensation angle when the steering station is working, and the angle compensation range is 0-5 degrees, that is, the forward steering range is 180-185 degrees, so that the material 300 can be turned closer to 180 degrees, thereby improving the accuracy of the material 300. At the same time, after the forward rotation is completed and the material 300 leaves the positioning groove 240 and rises with the suction nozzle 143, the steering motor 220 drives the positioning groove 240 to reverse 0-5 degrees, and corrects the extra 0-5 degrees when the positioning groove 240 rotates forward, so as to ensure that the positioning groove 240 is at a position of 180 degrees (equivalent to 0 degrees) when the material 300 arrives next time, and ensures the normal operation of the next steering positioning. This kind of reverse reset method has a shorter reset stroke than the existing steering station that reverses 180 degrees for reset. Therefore, this reset method ensures the accuracy of the steering station on the one hand, and shortens the station operation time on the other hand, effectively shortens the operation rhythm of the entire equipment, achieves the purpose of saving time, and thus improves production capacity.

[0040] like Figure 5 As shown, preferably, the positioning groove 240 includes a main body 241, a U-shaped groove 242 with a flat bottom surface is arranged in the middle of the main body 241, and limit blocks 243 are arranged at both ends of the U-shaped groove 242. Positioning components 244 are symmetrically arranged in the middle of both sides of the U-shaped groove 242, and the positioning components 244 are closely attached to the side of the main body 241 and fixedly connected to the steering seat 230. The design of the limit blocks 243 and the positioning components 244 cooperating with each other can limit and position the material 300 falling into the positioning groove 240 from four sides to ensure the positioning accuracy, and at the same time ensure that when the positioning groove 240 rotates, the material 300 is effectively rotated by the push of the positioning components 244 and the limit blocks 243.

[0041] Furthermore, the positioning component 244 includes two limiting columns 245 of the same structure, the two limiting columns 245 are symmetrical with respect to the central axis of the U-shaped groove 242, and the distance between the two limiting columns 245 and the distance between the two limiting columns 245 and the limiting block 243 are greater than the width of the standard electronic component pins. The positioning component 244 is composed of two limiting columns 245. On the one hand, it can ensure that the positioning component 244 performs a planar limit on the side of the material 300, and the limiting positioning area is large, which can prevent the material 300 from sliding out of the side of the U-shaped groove 242; on the other hand, the side of the U-shaped groove 242 is divided into three grids, which is convenient for the pins of the material 300 to pass through, and it is convenient to realize the positioning and limiting of the entire material 300 by positioning and limiting the pins of the material 300; at the same time, the positioning groove 240 can be applied to materials 300 of the same size but with 2-6 pins, thereby greatly improving the versatility of the equipment and effectively reducing the equipment cost. The height of the two limiting columns 245 is smaller than the height of the upper surface of the material 300 when the material 300 is placed in the U-shaped groove 242 , so as to avoid obstruction when the suction nozzle 143 sucks the material 300 .

[0042] like Figure 5 As shown, preferably, a guide groove 246 is provided in the middle of the stop block 243, the guide grooves 246 of the two stop blocks 243 are collinear, and the bottom surface of the guide groove 246 is not lower than the bottom surface of the U-shaped groove 242. Figure 2As shown, the first photoelectric mounting board 250 and the second photoelectric mounting board 260 are respectively arranged on both sides of the steering seat 230. The first photoelectric mounting board 250 and the second photoelectric mounting board 260 are collinear with the guide groove 246 when the steering seat 230 is in the initial position. A light emitting lamp 251 is arranged on the side of the first photoelectric mounting board 250 opposite to the steering seat 230, and a fiber optic transceiver 261 is arranged on the side of the second photoelectric mounting board 260 opposite to the steering seat 230; the light emitting lamp 251, the two guide grooves 246 in the initial state and the fiber optic transceiver 261 are collinear. In a specific implementation, the fiber optic transceiver 261 and the light emitting lamp 251 are evenly electrically connected to the control system of the machine, so as to facilitate the detection of the presence or absence of the material 300. The guide groove 246, the light emitting lamp 251 and the fiber optic transceiver 261 cooperate with each other to effectively monitor whether there is material 300 in the positioning groove 240, so as to determine whether the steering seat 230 performs the steering work. In specific operation, when the positioning groove 240 is in the initial position, that is, not turning, the guide groove 246, the light emitting lamp 251 and the optical fiber transceiver 261 are on the same straight line, and the light emitted by the light emitting lamp 251 is received by the optical fiber transceiver 261 through the guide groove 246. At this time, there is no material 300 in the positioning groove 240. After the suction nozzle 143 drives the material 300 to descend into the positioning groove 240, the material 300 is located between the two guide grooves 246, and the top surface of the material 300 is higher than the bottom surface of the guide groove 246. At this time, the light emitting lamp 251 The emitted light passes through the guide groove 246 located near the first optoelectronic mounting plate 250, and is blocked by the material 300 and cannot be transmitted into the guide groove 246 located near the second optoelectronic mounting plate 260, so that the optical fiber transceiver 261 cannot receive the optical signal from the opposite side. At this time, the optical fiber transceiver 261 feeds back the information that the optical signal is not received to the control system. The control system pre-sets that the absence of the optical signal is information that there is a material 300. In this way, when there is a material 300, the control system drives the steering motor 220 to steer and position.

[0043] like Figure 2 and Figure 3 As shown, preferably, a positioning substrate 270 is fixedly mounted on the second optoelectronic mounting board 260, the positioning substrate 270 is located on the right side of the positioning groove 240 and is parallel to the extension direction of the guide groove 246 in the initial state, and the head end of the positioning substrate 270 is located directly above the right side edge of the bottom surface of the U-shaped groove 242. Furthermore, as Figure 6 As shown, the head end of the positioning base plate 270 is F-shaped and includes two limit plates 271 of the same structure, and the two limit plates 271 are respectively located on both sides of the positioning assembly 244 on the right side of the U-shaped groove 242. The width of the limit plate 271 is smaller than the distance between the limit column 245 and the adjacent limit block 243, so as to prevent the positioning groove 240 from hitting the limit plate 271 when rotating.

[0044] As mentioned above, due to the installation position error and the gap between the size of the positioning groove 240 and the material 300, there will be errors in the rotation of the material 300 and angle compensation is performed. However, after the angle compensation, it cannot be accurately guaranteed that the rotation angle of the material 300 is indeed 180 degrees. Therefore, the setting of the positioning substrate 270 completely solves this problem. Specifically, a positioning substrate 270 is set on the right side of the positioning groove 240, which is equivalent to a reference positioning component. Its extension direction is the same as the initial standard 0-degree extension direction of the positioning groove 240, and it is just above the right side of the bottom surface of the positioning groove 240. At the same time, its height is less than the height of the flat end of the suction nozzle 143 when the suction nozzle 143 drops to the bottom, so as to avoid collision damage between devices. At the same time, the limiting plate 271 located on the positioning substrate 270 avoids the limiting block 243 and the positioning component 244, and the height of the bottom edge of the limiting plate 271 is higher than the bottom surface of the positioning groove 240, and lower than the top surface of the material 300 after the material 300 is placed. In this way, when there is material 300, the material 300 can be blocked to prevent excessive rotation. When there is no material 300 and the positioning groove 240 is reset and rotated, it can also avoid obstruction. Taking the compensation angle of 5 degrees as an example, the positioning substrate 270 is set so that the positioning groove 240 drives the material 300 to rotate forwardly at an angle of 185 degrees. At this time, the material 300 may rotate forwardly 180 degrees or more than 180 degrees. In this case, there may be a problem of excessive forward rotation. Although it is within the allowable error range at this time, in order to further reduce the error, the positioning substrate 270 is set to block the rotation of the material 300 from the right side of the material 300 to ensure that the rotation angle of the material 300 is exactly 180 degrees. This can further improve the accuracy of the turning of the material 300.

[0045] like Figure 7 As shown, a novel method for high-efficiency operation of a turning station of a continuous machine includes the following steps:

[0046] S1: setting the dynamic-static ratio of the driving motor 120, i.e., the DD motor, according to different detection components, so as to complete the detection action of each workstation in the shortest time;

[0047] S2: After the previous station completes the corresponding work, the driving motor 120 rotates a step angle, so that the suction nozzle assembly 140 rotates to the top of the turning station assembly 200;

[0048] S3: The nozzle motor 141 rotates to drive the nozzle assembly 140 to bring the material down, and the time consumed is T1;

[0049] S4: The steering motor 220 drives the steering seat 230 of the steering station assembly 200 to rotate forward by a step angle, the step angle range is 180-185 degrees, and the consuming time is T2;

[0050] S5: The nozzle motor 141 reverses 0-5 degrees, and the nozzle assembly 140 rises with the material, and the consumption time is T3;

[0051] S6: while S5 is being performed, the steering motor 220 drives the steering seat 230 to reverse by 0-5 degrees to compensate for the extra rotation angle in step S4, thereby completing the resetting of the steering seat 230, and the time consumed at this time is T4;

[0052] S7: During the execution of S5, the driving motor 120 waits for other stations to meet their starting conditions. When the suction nozzles 143 at other stations are all raised, the driving motor 120 drives the suction nozzle assembly 140 to turn to the next station. During this process, the suction nozzle assembly 140 is always in a vacuum state.

[0053] It should be pointed out that the station before the turning station is the direction detection station. If the direction is reversed, then in step S4, the steering motor rotates to drive the material to turn for direction adjustment, and continue with subsequent steps to complete the direction change; if it is detected in the previous station that the direction is not reversed, then in step S3, the material is lowered into the positioning groove, the material is positioned, and then the material is sucked away by the suction nozzle without performing the turning operation in step S4.

[0054] The high-efficiency working method of the present invention uses the DD motor seat core transfer component to accurately rotate and position the suction nozzle 143 component, improve the positioning accuracy of the suction nozzle assembly 140, and avoid the suction nozzle 143 failing to suck the material 300 and causing empty operation, causing the equipment to fail to operate normally. At the same time, a servo motor is used to drive the steering seat 230 to rotate, and the acceleration time is shorter. At the same time, the forward and reverse angles can be set to achieve angle compensation for the steering of the material 300, and achieve more accurate steering of the material 300. By improving the accuracy of the equipment operation, it is ensured that the equipment can work normally for a long time, which can also indirectly improve the production capacity of the equipment. Since it can work for a long time and the equipment will not stop due to a malfunction, it can ensure long-term high-speed production of the equipment. During the production process, the suction nozzle motor 141 rotates to drive the suction nozzle 143 to bring the material down. After the suction nozzle 143 descends and drives the material 300 to enter the positioning groove 240, the suction nozzle 143 breaks the vacuum and loses the attraction to the material 300. The steering motor 220 turns to a step angle of 180-185 degrees, and then the suction nozzle 143 creates a vacuum to suck the material 300. The suction nozzle motor 141 reverses the suction nozzle 143 to bring the material up, and then the steering motor 220 drives the positioning groove 240 to reverse 0-5 degrees. At the same time, the system waits for other stations to meet the conditions for the DD motor to start. After the conditions are met, the DD motor rotates, and the suction nozzle 143 brings the material into the next station. During this process, the suction nozzle 143 is always in a vacuum state. In this process, since the steering motor 220 only reverses 0-5 degrees for reset, compared with the prior art reversal of 180 degrees, the reset time is greatly shortened, thus shortening the rhythm of the steering station rotation and reset, facilitating timely acceptance of the material 300 brought by the next suction nozzle 143, thereby improving work efficiency. At the same time, when the suction nozzle 143 is rising, the steering motor 220 drives the positioning groove 240 to reverse, that is, further increasing the time taken by the positioning groove 240 to reset, thereby further shortening the time taken by the steering station, thereby shortening the beat of the steering station. That is, in this method, firstly, T3 is greatly shortened compared with the prior art, and secondly, T3 and T2 are partially overlapped, that is, when the suction nozzle 143 is rising, the steering motor 220 drives the positioning groove 240 to reverse, thereby partially overlapping the time, thus further shortening the working time of the steering station in the operation of the entire equipment, thereby reducing the waiting time after the suction nozzle 143 rises, so that the equipment can rotate faster to enter the steering action of the next material 300.

[0055] As described above, the present invention provides a novel steering station of a consistent machine and a method for its high-efficiency operation: (1) By arbitrarily setting the dynamic-static ratio of the DD motor, the optimal time interval for the rotation of the DD motor can be set according to the different time requirements of different materials, replacing the fixed dynamic-static ratio of the existing cam divider, making the beat control more flexible, reducing the use of invalid time, thereby effectively saving equipment operation time and improving equipment operation capacity; (2) The DD motor improves the equipment operation accuracy, making the relative position of the positioning groove of the suction nozzle assembly and the steering station assembly more accurate, and at the same time using a servo motor to drive the steering seat to rotate, the steering response time is shorter, thereby saving the steering station. The total movement time required; (3) The steering seat rotates at an angle of more than 180 degrees, and the excess angle is 0-5 degrees, which can effectively compensate for the rotation angle error caused by the rotation inconsistency caused by the gap between the material and the positioning groove, so that the material rotation angle is closer to 180 degrees, realizing the compensation of the material rotation angle, improving the material steering accuracy, and facilitating the detection of subsequent workstations; (4) After the angle compensation, the steering seat is reversed and reset by 0-5 degrees, which effectively reduces the reset time of the steering station, thereby effectively reducing the time required for the entire workstation to work. (5) The setting of the U-shaped groove and the positioning component further improves the steering station's control of the material entering the positioning groove. The position limit behind the positioning slot makes the positioning more accurate. At the same time, when the steering seat rotates, the two sides of the U-shaped slot cooperate with the positioning component to achieve effective tracking of the material, thereby reducing the angular error of the material rotation and improving the steering accuracy; (6) The positioning component is divided into two limiting columns, which divide the open two sides of the U-shaped slot into three grids, which is convenient for positioning and limiting the pins of the material. At the same time, the positioning slot can be used for materials of the same size but with 2-6 pins, thereby greatly improving the versatility of the equipment and effectively reducing the equipment cost; (7) The guide slot, light and optical fiber transceiver cooperate with each other to effectively monitor whether there is material in the positioning slot. Determines whether the steering seat performs steering work; (8) The positioning substrate is used to be parallel to the left side of the positioning component on the right side when the steering seat rotates 180 degrees, so that when the positioning slot continues to rotate with the steering seat, the positioning substrate is used to calibrate the material. When the material is in contact with the positioning substrate, the material stops rotating, thereby ensuring that the material rotation angle is 180 degrees, further improving the steering accuracy of the material; (9) The positioning substrate is F-shaped, which is convenient for avoiding the positioning component, further ensuring the accuracy of positioning, and can limit positioning from both ends of the material. When both ends of the material are in contact with the limit plates of the positioning substrate, the material is turned to 180 degrees, further improving the steering accuracy;(10) The method of the present invention shortens the working cycle of the entire turning station by controlling the rhythm of each step. At the same time, the turning seat only needs to perform a 0-5 turning reset, and resets synchronously after the suction nozzle assembly with the material rises, and the reset time is extremely short. Therefore, as long as the suction nozzles of other stations are also in the state of suction nozzle rising, the first turntable can rotate, and the suction nozzle can achieve the final reset during the rotation process, thereby shortening the rotation interval of the first turntable, thereby greatly shortening the operation cycle, thereby improving the equipment operation capacity. ;
