Description

Technical Field

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

[0002] In the production of SMT electronic components, the equipment that combines the production processes of testing, marking, visual inspection, and edge banding 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] Existing loading stations usually use a linear feeder to directly vibrate and feed the material. The material is sent to the end of the feeder and then limited by a complex limit device to prevent the material from falling off. The limit device is not started until the separator is in place to release the material. This structure is cumbersome to operate, wastes work hours, and prolongs the loading time. In addition, it is easy to cause the material transferred to the separator to skew, resulting in the subsequent workstations being unable to work normally.

[0004] At the same time, in the prior art, the control logic of the loading station is as follows: Figure 1 As shown, the working steps are as follows:

[0005] Step 1: The cylinder pushes and the suction nozzle rises with the material, and the required time is T4;

[0006] Step 2: The cam divider rotates, driving the nozzle to rotate a step angle, and the required time is T3;

[0007] Step 3: The cylinder returns, the suction nozzle descends, and the material is taken out. The time required is T2;

[0008] Step 4: The time required for material feeding is T1. Steps 1, 2, 3, and 4 are repeated.

[0009] Through analyzing the above steps, it is found that the existing technology has defects: each component is a serial action, the action cycle S=T1+T2+T3+T4, the subsequent steps must wait for the completion of the previous steps before they can be carried out, the action cycle is long, resulting in the subsequent workstations needing to wait for the loading station to load materials before they can carry out the work of the subsequent workstations.

If there is material, the circular vibration component stops vibrating, and if there is no material, the circular vibration component continues to vibrate and feed. Realize intermittent vibration feeding, thereby effectively saving energy; (3) A convex ridge is arranged under the elastic blocking structure, which can utilize the characteristics of the support shaft to push and squeeze the convex ridge to cause the convex ridge to slide along the support shaft.

Therefore, the stopper has a good limiting effect to ensure the accurate position of the material during loading; (6) The extension section is set to limit and guide the material from both sides when the material is transferred from the vibration trough to the receiving platform, so that the material can smoothly reach the designated position on the receiving platform and prevent the material from running off the track; (7) The vibration trough has a 0-5 degree inclination to facilitate the forward movement of the material during the vibration process; (8) The vibration trough gradually becomes narrower. On the one hand, the wider entrance relative to the width of the material can facilitate the material to enter from the outlet of the circular vibration component. On the one hand, the groove becomes narrower and narrower, which can facilitate the material to be arranged more neatly during vibration, and can reduce the error of material deviation when the material is transferred from the outlet to the separator assembly; (9) The setting of the blowing nozzle can blow air from the entrance of the vibration groove to the outlet of the vibration groove, so that the material can be driven forward while vibrating and moving forward, which is more convenient for the material to move forward; (10) The working method of the present invention can incorporate the time of material separation into the process of the previous suction nozzle carrying the material forward and the next suction nozzle arriving empty-handed, thereby effectively shortening the working time and improving work efficiency. The control system adds conditional judgment to improve the stability of the equipment and is suitable for high-speed occasions. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] 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.

[0042] Please refer to Figure 1 and Figure 2 The present invention provides a high-precision feeding station for a continuous machine, comprising a circular vibration component 1, a direct vibration component 2 and a separator component 3, wherein the discharge port of the circular vibration component 1 is connected to the feed port of the direct vibration component 2, and the feed port of the direct vibration component 2 is docked with the separator component 3; the direct vibration component 2 comprises a bracket 21 and a vibration trough 22, the vibration trough 22 is fixedly mounted on the bracket 21, and the outlet of the vibration trough 22 is docked with the separator component 3; an elastic blocking structure 23 is arranged at the outlet of the vibration trough 22, and the elastic blocking structure 23 comprises a downward The bent limiting protrusion 231 can be movably inserted into the outlet of the vibration groove 22 from the top of the vibration groove 22, so as to realize the opening and closing of the outlet of the vibration groove; the separator assembly 3 includes a receiving platform 31, the upper surface of the receiving platform 31 is connected to the bottom surface of the outlet of the vibration groove 22 and is located on the same horizontal plane when loading; a lifting assembly 32 is arranged on the side of the receiving platform 31 opposite to the elastic blocking structure 23, and the lifting assembly 32 is supported under the elastic blocking structure 23 when loading the receiving platform 31.

[0043] like Figure 1 and Figure 2As shown, in one embodiment, the circular vibration component 1 is used to vibrate and sort the disorderly scattered materials, and continuously convey them to the direct vibration component 2; after the inlet of the direct vibration component 2 receives the materials conveyed by the outlet of the circular vibration component 1, the materials entering the vibration trough 22 are continuously pushed forward by continuous vibration until they reach the outlet position of the vibration trough 22, and the elastic blocking structure 23 is used to limit the materials to prevent them from moving forward; a sensor is provided on the groove edge of the vibration trough 22, and the sensor is electrically connected to the control system of the entire equipment. When the sensor senses that there is material at the outlet of the vibration trough 22, it indicates that material separation and loading can be performed; then the separator motor 33 rotates, and the receiving platform 31 is pushed forward to align with the outlet of the vibration trough 22 and spliced ​​together. During the advancement of the receiving platform 31, the jacking component 32 moves forward together with the receiving platform 31 The material is then moved forward by the movement of the separator motor 33 to move the receiving platform 31 and the material is moved to the receiving platform 31. At the same time, the transfer component 4 of the continuous machine rotates a step angle to drive the unloaded suction nozzle component 41 to the top of the receiving platform 31. The suction nozzle motor 411 reverses to press the suction nozzle component 41 down onto the material and suck up the material. Then the suction nozzle motor 411 rotates to bring the material up. After the control system determines that the turntable 42 can rotate, the transfer component 4 drives the suction nozzle component 41 with the material to rotate a step angle to enter the top of the first detection station, thereby realizing the material loading work.

[0044] like Figure 3 As shown, preferably, the elastic blocking structure 23 is an L-shaped elastic sheet, including a first section 232 and a second section 233 which are perpendicular to each other and connected in one piece, the first section 232 is fixedly mounted on the right side of the vibration groove 22, the second section 233 is mounted on the upper surface of the vibration groove 22, and the limiting protrusion 231 is connected in one piece to the lower side of the second section 233 away from the first section 232. The elastic blocking structure 23 is set in an L shape and fixed on the side of the vibration groove 22, so that it can avoid the top of the vibration groove 22, so that the top of the vibration groove 22 is unobstructed, so that the sensor set on the upper edge of the vibration groove 22 can timely sense whether there is material in the vibration groove 22, the sensor, the circular vibration component 1 and the direct vibration component 2 are all electrically connected to the control system of the consistent machine, and the sensor senses whether there is material and transmits the information to the control system, if there is material, the control system drives the circular vibration component 1 to stop vibrating, if there is no material, the control system drives the circular vibration component 1 to vibrate and continue to feed, so as to achieve intermittent vibration feeding, thereby effectively saving energy.

[0045] like Figure 3As shown, preferably, a ridge 234 is fixedly installed on the lower side surface of the first section 232 near one end of the second section 233, and the ridge 234 is a right-angled trapezoid. The lower bottom surface of the ridge 234 is fixed on the lower side surface of the first section 232, and the inclined surface 235 of the ridge 234 is opposite to the lifting assembly 32; the lifting assembly 32 includes a support shaft 321 parallel to the second section 233, and the support shaft 321 is located below the elastic blocking structure 23 and at the intersection of the inclined surface 235 of the ridge 234 and the lower surface of the first section 232; when the ridge 234 is connected to the outlet of the receiving platform 31 and the vibration groove 22, the height supported by the support shaft 321 is greater than the height of the limiting protrusion 231. The convex rib 234 with the inclined surface 235 cooperates with the support shaft 321, and can utilize the support shaft 321 to push and squeeze the convex rib 234 to cause the convex rib 234 to slide up along the support shaft 321, and directly push up the elastic blocking structure 23 when the receiving platform 31 gradually moves forward, and the height of the convex rib 234 is greater than the height of the limiting protrusion 231, so that the limiting protrusion 231 can leave the vibration groove 22, and at this time the vibration groove 22 continues to vibrate to release the material, so that the material can smoothly reach the receiving platform 31. This structure is simple and fast, and is fully opened as the receiving platform 31 is in place. It is an interconnected structure without delay, and when the receiving platform 31 is returned with the material, the convex rib 234 loses the support of the support shaft 321, and will fall in time under the elastic resetting action of gravity and the elastic blocking structure 23, driving the limiting protrusion 231 to be reinserted at the outlet of the vibration groove 22 to prevent excess material from flowing out.

[0046] like Figure 4 As shown, in another embodiment, the elastic blocking structure 23 has another supporting structure, that is, the upper surface of the jacking assembly 32 is provided with an upwardly inclined support block 322, the inclined surface of the support block 322 is opposite to the second section 233, and the lowest end of the inclined surface of the support block 322 is located below the second section 233 and in contact with the second section 233; when the receiving platform 31 and the outlet of the vibration groove 22 are docked together, the height of the second section 233 supported by the inclined surface of the support block 322 is greater than the height of the limiting protrusion 231. In this structure, while the receiving platform 31 is pushed toward the vibration groove 22, the elastic blocking structure 23 is still supported upward by the inclined surface of the support block 322, and the second section 233 moves forward along the inclined surface of the support block 322 until the receiving platform 31 and the outlet of the vibration groove 22 are docked. At this time, since the height of the second end supported is greater than the height of the limiting protrusion 231, it can ensure that the limiting protrusion 231 can be supported synchronously and leave the vibration groove 22, so that the material can be released.

[0047] Preferably, a left cover plate 221 and a right cover plate 222 are fixedly mounted on the groove edges of both sides of the vibration groove 22, and a gap is set between the left cover plate 221 and the right cover plate 222, so as to facilitate observation from the top of the vibration groove 22 whether there is material in the vibration groove 22, and the left cover plate 221 and the right cover plate 222 reach the same height at the bottom of the groove and the height is less than twice the height of the material. The setting of the left cover plate 221 and the right cover plate 222 can limit the material from the top of the vibration groove 22 to prevent the material from being shaken out from the top of the vibration groove 22 when vibrating forward, and the distance between the cover plate and the bottom of the vibration groove 22 is less than twice the height of the material, so as to facilitate the material to be arranged more flatly in the process of the material moving along the vibration groove 22 to prevent the material from stacking.

[0048] like Figure 3 As shown, preferably, the left cover plate 221 and the right cover plate 222 are both L-shaped cover plates, the vertical side surfaces 223 of the left cover plate 221 and the right cover plate 222 are inserted into the vibration groove 22, and the horizontal side surfaces 224 of the left cover plate 221 and the right cover plate 222 are mounted above the groove edge of the upper vibration groove 22; the vertical side surfaces 223 of the left cover plate 221 and the right cover plate 222 are both integrally connected with an extension section 225, the extension section 225 protrudes in front of the outlet of the vibration groove 22, and the extension sections 225 are symmetrically arranged on both sides of the receiving platform 31. The left cover plate 221 and the right cover plate 222 are both configured to be L-shaped covers bent at right angles. The horizontal side surface 224 is used to fix the cover plate and block the top of the vibration groove 22. At the same time, the vertical side surface 223 can be pushed to the middle of the vibration groove 22, so that most of the vibration groove 22 is blocked. At the same time, the two vertical side surfaces 223 are respectively located on both sides of the material body and above the material pin. As the vibration groove 22 extends, the distance between the bottom end of the vertical side surface 223 and the bottom surface of the vibration groove 22 becomes smaller. In this way, when reaching the outlet of the vibration groove 22, the two vertical side surfaces 223 can be limited on both sides of the material body, and the bottom surface height of the vertical side surface 223 is less than the top surface height of the material. In this way, the material can be effectively limited to prevent the material from tilting in the vibration groove 22; the extension section 225 is set to limit and guide the material from both sides when the material is transferred from the vibration groove 22 to the receiving platform 31, so that the material can smoothly reach the designated position on the receiving platform 31 to prevent the material from running off.

[0049] like Figure 5As shown, preferably, the receiving platform 31 is in a step shape, and a stopper 311 is provided at its rear end, and the stopper 311 is integrally connected with the receiving platform 31. Limiting grooves 312 are provided on both sides of the receiving platform 31, and the two extension sections 225 are respectively slidably located in the limiting grooves 312. The receiving platform 31 is designed to be in a step shape, and the lower plane is used to receive the material, and the relatively higher stopper 311 is used to prevent the material from continuously advancing forward during vibration advancement, resulting in position errors. Therefore, the stopper 311 has a good limiting effect, avoids excessive feeding of the material, and ensures the accurate position of the material during loading. The limiting grooves 312 provided on both sides of the receiving platform 31 can provide guidance for the extension section 225 to advance. At the same time, the height of the lowest plane of the receiving platform 31 is higher than the height of the lowest surface of the extension section 225, so as to prevent the material from falling from the gap between the receiving platform 31 and the extension section 225.

[0050] Preferably, the vibration trough 22 is tilted downward by 0-5 degrees from the direction of the circular vibration component 1 to the separator component 3, so that the material can move forward with the help of gravity during the vibration process, thereby achieving a better effect of vibration feeding.

[0051] Preferably, the vibration trough 22 gradually narrows from its inlet end to its outlet end. On the one hand, the wider inlet relative to the width of the material can facilitate the material to enter the vibration trough 22 from the outlet of the circular vibration component 1. On the other hand, the increasingly narrow trough can facilitate the material to be arranged more neatly during vibration, and when the material comes out of the outlet and is transferred to the separator component 3, the error of material deviation can be reduced.

[0052] Preferably, a blowing nozzle is provided above the inlet end of the vibration trough 22, and the blowing nozzle is tilted toward the outlet end of the vibration trough 22. The setting of the blowing nozzle can blow air from the inlet of the vibration trough 22 to the outlet of the vibration trough 22, so that the material can be driven forward while vibrating and moving forward, which is more convenient for the material to move forward.

[0053] like Figure 3As shown, preferably, a guide plate 211 is fixedly installed at the bottom of the bracket 21, and the guide plate 211 is located directly below the vibration groove 22. A positioning guide strip 212 is integrally connected to the guide plate 211, and the positioning guide strip 212 is parallel to the vibration groove 22 and is located directly below the vibration groove 22; the separator assembly 3 also includes a support frame 34, a separator motor 33 and a separation assembly 35, the support frame 34 includes an L-shaped main positioning plate 341, and an L-shaped auxiliary positioning plate 342, the main positioning plate 341 includes an integrally connected horizontal bottom plate 3411 and a vertical side plate 3412, and the bottom surface of the bottom plate 3411 is opened. A positioning guide groove 3413 is provided, and a positioning guide bar 212 is inserted into the positioning guide groove 3413. One end of the auxiliary positioning plate 342 is fixed to the side of the side plate 3412, and the other end of the auxiliary positioning plate 342 is vertically erected on both sides of the vibration groove 22. The elastic blocking structure 23 is fixedly installed above the auxiliary positioning plate 342 located on the right side of the vibration groove 22; the separator motor 33 is fixedly installed on the lower side of the separation component 35, and the receiving platform 31 is movably installed on the side of the separation component 35 opposite to the vibration groove 22. The separation component 35 includes a connecting plate 351, and the connecting plate 351 is fixedly installed on the right side surface of the side plate 3412. The positioning guide bar 212 cooperates with the positioning guide groove 3413 to make the installation position of the separator component 3 more accurate, reduce the installation error, and thus make the feeding more accurate.

[0054] like Figure 6 As shown, a high-efficiency working method for a high-precision loading station of a continuous machine includes the following steps:

[0055] S1: Material discharge: A sufficient amount of materials to be tested and packaged is stored in the hopper, and the materials are automatically filled into the circular vibration component 1 by judging whether there is material in the circular vibration component; specifically, a sensor is arranged on the feeding track of the circular vibration component, and the sensor senses whether there is material on the track and transmits the corresponding information to the control system. When there is material, the control system outputs a signal to release the material to the hopper, and the hopper opens the valve after receiving the signal to release the material into the circular vibration component;

[0056] S2: Sorting: Use the circular vibration component 1 to vibrate and sort the bulk materials;

[0057] S3: Feeding: The materials sorted by circular vibration are transferred to the direct vibration component 2 for sequential forward movement, so as to achieve continuous forward feeding;

[0058] S4: Transfer: The separator motor rotates to push the receiving platform 31 forward to connect with the vibration trough 22. During the arrival of the separation component 35, the limiting protrusion 231 is gradually pushed up and raised, thereby releasing the material to reach the receiving platform 31.

[0059] S5: Positioning: The material falls onto the receiving platform 31, and a vacuum is created in the vacuum pipe connected to the receiving platform 31, so that the material is firmly adsorbed on the receiving platform 31;

[0060] S6: Separation: The separator motor reverses to drive the receiving platform 31 to reset and return, thus achieving separation;

[0061] S7: Loading 1: During the process of step S6, the transfer assembly rotates a step angle to transfer the empty suction nozzle to the top of the receiving platform 31;

[0062] S8: Material loading 2: The suction nozzle motor reverses, the suction nozzle descends, and at the same time the receiving platform 31 breaks the vacuum to remove the attraction of the material. After the suction nozzle successfully absorbs the material, the suction nozzle motor rotates forward, and the suction nozzle rises with the material;

[0063] S9: Loading 3: The control system determines the conditions for the turntable to drive the nozzle to rotate. After all stations have completed the action, the transfer component will transfer another step angle. At the same time, the nozzle motor reverses and the nozzle descends with the material to enter the first inspection station for inspection;

[0064] S10: When S8 is completed and the suction nozzle is rising with the material, the separator assembly 3 implements the cyclic operation of S4-S7, that is, when the suction nozzle is rising with the material and the next suction nozzle is descending to take the material, the separator assembly 3 completes S4-S7 to separate the materials.

[0065] The method provided by the present invention, when working at the loading station, incorporates the action time of the separator assembly 3 into the cycle from the previous suction nozzle assembly rising with the material to the next suction nozzle rotating and descending, and realizes the effective picking up of the material, avoiding the waiting for the material separation after the suction nozzle arrives, greatly shortening the material picking time, thereby improving the material loading efficiency, and then improving the working efficiency of the entire equipment.

[0066] The present invention uses a DD motor to replace the cam divider to drive the turntable to rotate, driving the nozzle to rotate a step angle, thereby improving the rotation accuracy, and being able to arbitrarily set the dynamic-static ratio, and being able to determine the shortest waiting time according to the action time of each station, thereby effectively improving production efficiency and reducing the consumption of useless time. At the same time, the nozzle is driven by a nozzle motor. Compared with the fixed push stroke of the cylinder, the nozzle motor has an adjustable running speed, which can be applied to different products.

[0067] As described above, the present invention provides a high-precision loading station for a continuous machine and a high-efficiency working method thereof. (1) By setting an elastic blocking structure, its structural characteristics can be directly used for limiting the position. At the same time, the lifting component of the separation component is used. The two cooperate with each other. When the separator component arrives, the elastic blocking structure can be directly propped up by the forward advancement of the lifting component. This is simple and convenient. Not only is the limiting simple and convenient, but the material can also be released accurately and quickly to achieve synchronous operation. (2) The elastic blocking structure is L-shaped and can avoid the top of the vibration trough, so that there is no obstruction above the vibration trough, which is convenient for the sensor set on the upper edge of the vibration trough to timely sense whether there is material in the vibration trough. If there is material, the vibration component stops vibrating. If there is no material, the vibration component stops vibrating. The vibration assembly continues to feed the material, realizing intermittent vibration feeding, thereby effectively saving energy; (3) a convex ridge is arranged under the elastic blocking structure, which can utilize the characteristics of the support shaft to push and squeeze the convex ridge to cause the convex ridge to slide along the support shaft. When the separator is gradually advanced, the elastic blocking structure is directly pushed up to release the material. This structure is simple and fast, and it is fully opened with the arrival of the receiving platform without delay; (4) The arrangement of the left cover plate and the right cover plate can limit the material from the top of the vibration trough to prevent the material from being vibrated out from the top of the vibration trough when it is vibrating forward, and the distance between the cover plate and the bottom of the vibration trough is less than twice the height of the material, which makes it easier to arrange the material more flat as the material moves along the vibration trough. (5) The receiving platform is designed to be stepped, with a lower plane for receiving materials and a relatively higher stopper for preventing the materials from continuously moving forward during vibration and causing position errors. Therefore, the stopper has a good limiting effect and ensures the accurate position of the materials during loading. (6) The extension section is set to limit and guide the materials from both sides when the materials are transferred from the vibrating trough to the receiving platform, so that the materials can smoothly reach the designated position on the receiving platform and prevent the materials from running off the track. (7) The vibration trough has a 0-5 degree inclination to facilitate the forward movement of the materials during the vibration process. (8) The vibration trough gradually becomes narrower. On the one hand, the wider entrance relative to the width of the materials can facilitate the materials from the circular vibration component. The outlet enters the vibration trough, and on the other hand, the trough becomes narrower and narrower, which can facilitate the material to be arranged more neatly during vibration, and when the material is transferred from the outlet to the separator assembly, the error of material deviation can be reduced; (9) The setting of the blowing nozzle can blow air from the entrance of the vibration trough to the outlet of the vibration trough, so that the material can be driven forward while vibrating and moving forward, which is more convenient for the material to move forward; (10) The working method of the present invention can incorporate the material separation time into the process of the previous suction nozzle carrying the material forward and the next suction nozzle arriving empty-handed, thereby effectively shortening the working time and improving work efficiency. The control system adds conditional judgment to improve the stability of the equipment and is suitable for high-speed occasions.
