TECHNICAL FIELD
[0001] The utility model relates to material sorting equipment technical field, especially a kind of jig for latch sorting. BACKGROUND
[0002] In industrial production, as a commonly used connecting component, the specification and quality requirement of latch are often relatively strict. The traditional latch sorting method is mostly dependent on manual operation, and workers need to check the size, shape and other characteristics of latch one by one, and place them in categories. This manual sorting method has many drawbacks. First, manual sorting is inefficient, which is difficult to meet the needs of large-scale production, and is likely to cause production delay. Secondly, the accuracy of manual sorting is greatly affected by subjective factors of workers, and is likely to cause misjudgment and omission, thereby affecting the assembly quality and overall performance of products. In addition, long-term manual sorting work is intensive, which is likely to cause workers fatigue, further reducing the accuracy and efficiency of sorting.
[0003] Therefore, it is of great practical significance to design and develop a high-efficiency and accurate jig for latch sorting. SUMMARY
[0004] The utility model aims at providing a kind of jig for latch sorting, mainly used for the automatic classification screening of latch parts, to meet the requirements of different production processes or product assembly for specific specifications or quality of latch, improve production efficiency and stability of product quality, to solve the above technical problems.
[0005] To achieve the above technical scheme, the technical scheme of the utility model is as follows: a kind of jig for latch sorting mainly by jig base, sorting material channel that is obliquely installed on jig base, first switching component, second switching component and detection component. Jig base is the supporting basis of the whole jig, and provides stable mounting platform for other components. Sorting material channel is used to convey the latch to be sorted, and its oblique installation is conducive to the natural sliding of latch under the action of gravity, which is convenient for subsequent sorting operation. First switching component is rotatably arranged on sorting material channel, and undertakes the task of first-round material screening of latch. Second switching component is located below the left of first switching component, and performs second-round material screening on latch after first-round screening, to further subdivide the categories of latch. Detection component is arranged on the feed port of first switching component and second switching component, and triggers the swinging action of first switching component and second switching component by detecting specific characteristics or position information of latch, so as to guide latch into different collection channels and realize the separation and collection of latch.
[0006] Further, the first switching assembly comprises a first driving source, a switching shaft, a limiting seat and a distributing block. The first driving source is fixedly arranged at the bottom of the sorting channel and serves as the power core of the whole switching assembly. A double-acting rotary cylinder is selected as the first driving source. The rotary cylinder is firmly mounted on the sorting channel through a cylinder mounting seat and has the characteristics of compact structure, stable output torque, rapid action and easy control. The other output end of the rotary cylinder is detachably mounted with an elongated swing block. The swing block can be used in certain specific debugging or auxiliary operations. For example, when the equipment is initially installed and debugged, the swing block can be manually operated to simulate the movement of the rotary cylinder, so as to check whether the movement trajectory of the switching shaft and the distributing block is accurate.
[0007] Further, the switching shaft is rotatably arranged on the sorting channel and connected with the first driving source. The switching shaft can rotate back and forth under the driving of the rotary cylinder. The limiting seat is fixedly arranged on one side of the first driving source and arranged in a V shape. The two ends of the limiting seat are adjustably mounted with adjusting screws. The V-shaped limiting seat can effectively limit the rotation angle range of the switching shaft. The opening size of the limiting seat can be accurately fine-tuned through the adjusting screws, so as to change the rotation angle of the switching shaft to adapt to the sorting requirements of different specifications of the pins. For example, when the pins with small length difference need to be sorted, the opening of the limiting seat can be adjusted smaller through the adjusting screws, so that the rotation angle of the switching shaft is smaller, thereby realizing more accurate distributing action.
[0008] Further, the distributing block is fixedly arranged at the top end of the switching shaft and directly contacts with the pins for distributing operation. A rubber buffer pad is embedded on the distributing block. The rubber buffer pad has two main functions. On the one hand, when the distributing block contacts with the pins, the rubber buffer pad can play a buffering role to avoid damaging the surface quality of the pins or causing deformation of the pins due to hard collision, thereby ensuring the integrity and usability of the pins. On the other hand, the rubber buffer pad can increase the friction between the distributing block and the pins, so that the distributing action is more reliable and the pins are prevented from slipping or misjudging during the distributing process.
[0009] Further, the second switching assembly is arranged in the same structure as the first switching assembly and also comprises a driving source, a switching shaft, a limiting seat and a distributing block. The working principle and function of the second switching assembly are similar to those of the first switching assembly. In the whole sorting process, the second switching assembly further classifies the pins that have been preliminarily classified by the first switching assembly. Through twice switching classification in different positions and angles, the pins can be classified into more categories to meet more complex production requirements. For example, when the diameter and length of the pins are sorted at the same time, the first switching assembly can first classify the pins according to the length, and then the second switching assembly can further classify the pins that have passed the first round of classification according to the diameter, so as to realize multi-dimensional accurate sorting of the pins.
[0010] Further, the detection assembly adopts a light barrier photoelectric sensor, which has the advantages of high detection precision, fast response speed and strong reliability. The light barrier photoelectric sensor is installed on the feed port of the first switching assembly and the second switching assembly, and detects the passing situation or specific features of the plug by emitting and receiving light. When the plug passes through the detection area, the light will be blocked, and the sensor converts the change of the received light signal into an electric signal and transmits the signal to the control system. The control system judges the features or position information of the plug according to the received signal, and then controls the rotary cylinder of the first switching assembly and the second switching assembly to act, so that the distribution block swings to the corresponding position, and the plug is guided into different troughs for separation and collection. For example, when the length of the plug is detected to be greater than a set value, the control system can control the rotary cylinder of the first switching assembly to act, so that the distribution block guides the plug to a specific trough; when the plug passes through the feed port of the second switching assembly and the diameter does not meet the requirements, the detection assembly transmits a signal to the control system, and the control system controls the rotary cylinder of the second switching assembly to act, so that the plug is separated into another trough.
[0011] Further, the sorting channel is obliquely installed on the jig base, and the oblique angle is carefully designed to ensure that the plug can smoothly slide under the action of gravity and cannot slide too fast to cause inaccurate detection and distribution. The sorting channel is provided with a vibrator, which provides a certain vibration during the sliding of the plug to prevent the plug from being blocked or stuck in the channel. Especially for some plugs with slight roughness or irregular shape, the vibrator can keep them in good flowability in the channel, ensuring the continuity of the sorting process.
[0012] Further, the top of the sorting channel is provided with a feed groove, and the plug to be sorted enters the sorting channel through the feed groove. The top of the sorting channel is also provided with three troughs, and one end of each of the three troughs is in communication with one end of the feed groove. After being sorted by the first switching assembly and the second switching assembly, the plug will be guided into one of the three troughs, realizing the separation and collection of different types of plugs. The width, depth and surface smoothness of the troughs are designed according to the specifications and sorting requirements of the plug. For example, for a plug with a larger diameter, the width of the trough should be increased accordingly to ensure that the plug can smoothly enter the trough without being stuck.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1) The first switching assembly and the second switching assembly of the utility model cooperate and realize the multi-round screening of the bolt. The first switching assembly can screen the bolt in the first round and classify the bolt preliminarily. For example, the bolt can be divided into different approximate categories according to the length, diameter or head shape of the bolt. Then the second switching assembly is located below the left of the first switching assembly, the bolt screened in the first round is screened in the second round, and the bolt category is further subdivided. The two-stage screening structure can accurately classify the bolt according to multiple characteristics or standards, and meet the complex production requirements. For example, in the production of automobile parts, the bolts used for different types of automobile engines have slightly different size and shape requirements. Through the two-round screening of the jig, the bolt can be accurately sorted out, and the accuracy of product assembly and production efficiency are improved.
[0015] 2) The detection assembly of the utility model plays a key role in the feed port of the first switching assembly and the second switching assembly. The light emitting photoelectric sensor as the detection assembly can quickly and accurately detect the characteristics or position information of the bolt. When the bolt reaches the feed port, the sensor detects instantaneously and transmits the signal to the control system. For example, when detecting the length of the bolt, the sensor can accurately measure the time of the bolt blocking the light or the change of the light signal, so as to judge whether the length of the bolt meets the requirements. The control system triggers the first switching assembly or the second switching assembly to swing according to the detection result, guides the bolt into the corresponding chute, the whole process is rapid and accurate, effectively reduces the mis-sorting situation, and improves the stability of product quality.
[0016] 3) The first driving source of the first switching assembly of the utility model selects a double-acting output rotary cylinder. The rotary cylinder is installed on the sorting channel through the cylinder mounting seat, the output torque is stable, and reliable power can be provided for the switching shaft. In the long-time and high-intensity sorting work, the switching shaft can be continuously and stably driven to reciprocating rotate, ensuring the continuity of the sorting action. Moreover, the other output end of the rotary cylinder is detachably installed with a long strip-shaped swing block, which facilitates the use in equipment debugging, maintenance or special operation. For example, in the initial installation and debugging stage of the equipment, the swing block can be manually operated to simulate the movement of the rotary cylinder, check whether the movement track of the switching shaft and the sorting block is accurate, and timely find and solve potential problems, improve the reliability and maintainability of the equipment.
[0017] 4)The utility model discloses the adjustable installation of adjusting screw rod is provided with the V-shaped setting of the limiting seat, can accurately limit the rotation angle of switching pivot. When sorting different specifications of the bolt, the opening size of the limiting seat can be adjusted according to the characteristics of the bolt, so as to change the rotation angle of the switching pivot, make the material block accurately guide the bolt to the corresponding material groove. When the bolt with small diameter difference needs to be sorted, the opening of the limiting seat is reduced by fine adjustment adjusting screw rod, the rotation angle of the switching pivot is reduced, and the swing range of the material block is also reduced, realizing more accurate material distribution operation, and ensuring the accuracy and stability of sorting.
[0018] 5)The utility model discloses that rubber buffer pad is embedded on the material block, which plays a buffering role when the material block contacts the bolt, avoids hard collision and damages the surface quality of the bolt or causes the deformation of the bolt. When the bolt with high surface precision needs to be sorted, the rubber buffer pad can effectively protect the bolt. On the other hand, the rubber buffer pad increases the friction between the material block and the bolt, prevents the bolt from slipping or misjudging during the material distribution process, and further improves the reliability of the material distribution.
[0019] 6)The utility model discloses that the sorting material channel is obliquely installed on the jig base, and the oblique angle is optimized, which can ensure that the bolt can smoothly slide under the action of gravity, and will not affect the accuracy of detection and material distribution due to the too fast sliding speed. When the small size bolt needs to be sorted, the appropriate oblique angle can make the bolt slide through the detection area and the material distribution point slowly and stably, which is convenient for accurate detection of the detection assembly and accurate material distribution of the switching assembly.
[0020] 7)The utility model discloses that the vibrator is adhered on the sorting material channel, which effectively prevents the bolt from being blocked or stuck in the material channel. For some bolts with slight roughness or irregular shape, the vibration provided by the vibrator can keep the good fluidity. When the bolt with slight burr is handled, the vibrator can make the bolt smoothly pass through the material channel, ensure the continuity of the sorting process, and improve the adaptability of the jig to different types of bolts.
[0021] 8)The utility model discloses that the sorting material channel is provided with a feeding groove and three material grooves at the top, the feeding groove facilitates the batch entry of the bolt into the material channel, and the three material grooves can meet the classification needs of multiple types. When the bolt needs to be classified as qualified, unqualified and further detected, the three material grooves can correspond to the three situations respectively, which improves the sorting efficiency and practicability of the jig.
