Technical Field

The utility model belongs to the technical field of machinery, a three-dimensional storehouse formula temporary storage machine is related to.

Background

In a PCB processing production line, a temporary storage machine is generally arranged between two procedures to ensure that the continuity of the former procedure is not influenced by the latter procedure, if equipment corresponding to the latter procedure fails, the former procedure does not need to be stopped, and if the board conveying speed of the latter procedure is inconsistent with the board discharging speed of the former procedure, the two procedures can be continuously carried out through the temporary storage machine; the temporary storage machine is used for temporarily storing the plate to be produced or input in a certain process so as to supply the plate in time when the certain process is needed.

The temporary storage machine is including going into the grillage, go out the grillage and be located a plurality of temporary storage frame between the two, along with the propulsion of intelligent production, the production efficiency of each process all has promotion by a relatively large margin, current temporary storage machine is because each temporary storage frame all need set up solitary power unit, the quantity that makes a temporary storage machine's temporary storage frame can not be too many, current generally is 20 layers, panel gets into the temporary storage frame or when being exported by the temporary storage frame, need control to correspond the temporary storage frame and start its power, the defect that this kind of mode exists is: 1. the control of a certain temporary storage frame needs to acquire the position information corresponding to the plate entering frame or the plate discharging frame, and then the temporary storage frame action which is leveled with the plate entering frame or the plate discharging frame is started, so that the plates can enter the temporary storage frame from the plate entering frame or be output to the plate discharging frame from the temporary storage frame, the control is complex, and the failure rate is high; 2. each temporary storage frame needs to be provided with an independent power system, the existence of the power system of each temporary storage frame enables the layer height of the adjacent temporary storage frames to be larger, the number of the temporary storage frames of the temporary storage machine is limited, the increasing processing efficiency of each device cannot be met, and the matching of intelligent devices and the temporary storage machine is influenced; 3. the action of the temporary storage frame needs to be cooperated with the plate entering frame or the plate discharging frame, the requirement on the precision of controlling the action of the temporary storage frame is high, and faults such as clamping plates are easily caused; 4. when the front process and the rear process are asynchronous, particularly when the front process or the rear process has material changing or short halt, the existing temporary storage machine is difficult to have three functions of first-in first-out, last-in first-out and straight-through in and out; in summary: because each temporary storage frame of current temporary storage machine is controlled by each power device that independently exists respectively, can not be automatic, efficient with go into the grillage or go out the grillage in coordination, make panel get into the temporary storage frame or be difficult to match with going into the grillage and going out the grillage when going out the board from the temporary storage frame, make the function of temporary storage machine limited, efficiency limited, the fault rate is higher.

the plate conveying mechanism comprises a plate conveying frame which is longitudinally connected to the rack in a sliding mode, a plurality of second conveying rollers and a second transmission roller corresponding to the first transmission roller are rotatably connected to the plate conveying frame, the second transmission roller and the first transmission roller are coaxial when the temporary storage frame and the plate conveying frame are located on the same plane, second driven bevel gears are fixedly arranged on the second conveying rollers, a plurality of second driving bevel gears which correspond to the second driven bevel gears in a one-to-one mode are fixedly arranged on the second transmission rollers, the second driving bevel gears are meshed with second driven bevel gears corresponding to the second driving bevel gears, the second conveying rollers are perpendicular to the second transmission rollers, and a servo motor for driving the second transmission rollers to rotate is arranged on the plate conveying frame;

a contact-free clutch mechanism is arranged between the first driving roller and the second driving roller; the contact-free clutch mechanism comprises a first combination disc fixedly arranged at the end part of the first transmission roller, a second combination disc fixedly arranged on the temporary storage frame, a sliding sleeve connected to the second transmission roller in a sliding manner through a spline, a first active combination disc fixedly arranged on the sliding sleeve and a second active combination disc fixedly arranged on the sliding sleeve, wherein a clamping groove is formed between the first active combination disc and the second active combination disc;

the first combination disc is opposite to the active combination disc I, and the second combination disc is opposite to the active combination disc II; a first magnetic torque transmission assembly is arranged between the first combination disc and the first active combination disc, a second magnetic torque transmission assembly is arranged between the second combination disc and the second active combination disc, the first magnetic torque transmission assembly comprises a plurality of first permanent magnets and a plurality of second permanent magnets, the first permanent magnets are arranged on the first combination disc, the second permanent magnets are arranged on the first active combination disc, the first combination disc and the second active combination disc can attract each other when approaching, the second magnetic torque transmission assembly comprises a third permanent magnet and a fourth permanent magnet, the third permanent magnet is arranged on the second combination disc, the fourth permanent magnet is arranged on the second active combination disc, and the second combination disc and the second active combination disc can attract each other when approaching;

the air cylinder can control the first active combination disk to be close to the first combination disk under the condition that a gap is reserved between the first active combination disk and the first combination disk, and the air cylinder can control the second active combination disk to be close to the second combination disk under the condition that a gap is reserved between the second active combination disk and the second combination disk.

Furthermore, the width of the shifting pincers in the axial direction of the sliding sleeve is smaller than that of the clamping groove.

Furthermore, a gap is formed between the poking pliers and the bottom of the clamping groove.

Furthermore, two limiting snap springs for limiting the reciprocating motion limit positions of the sliding sleeve are arranged on the second transmission roller.

One limiting clamp spring is located between the second combination plate and the second active combination plate, and the other limiting clamp spring is also arranged on the second transmission roller and used for limiting the position of the first combination plate when the first combination plate and the second active combination plate are close to each other.

The two limit clamp springs have the following significance: when the shifting clamp fluctuates the sliding sleeve to enable the first combination plate to be close to the active combination plate, the shifting clamp is contacted with the inner side of the active combination plate at the moment of shifting the sliding sleeve to move, short-time relative friction exists between the shifting clamp and the active combination plate, however, when the air cylinder reaches the limit stroke, the limit clamp spring positioned between the active combination plate I and the first combination plate is not abutted against the sliding sleeve, the sliding sleeve also has a space which continues to move towards the direction of the first combination plate, the space is driven by the adsorption force between the first combination plate I and the active combination plate I until the sliding sleeve is limited by the corresponding limit clamp spring, in the process, the shifting clamp realizes the separation from the inner side of the active combination plate I, a gap exists between the active combination plate I and the first combination plate I, and under the condition of being capable of transmitting torque, the external force required for the separation of the active combination plate I and the first combination plate is not too large, the phenomenon that the air cylinder acts slowly or cannot reliably push the sliding sleeve is avoided; the same principle is adopted when the sliding sleeve is driven to move reversely. It can be easily seen that because the limiting snap spring is arranged on the second transmission roller, relative friction does not exist between the limiting snap spring and the sliding sleeve, only slight impact exists, and friction generated by the rotation of the sliding sleeve on the inner side of the poking clamp and the inner side of the first active combination disk or the inner side of the second active combination disk is only transient, namely, the relative friction exists at the moment of poking the sliding sleeve to move, and then the poking clamp is separated from the first active combination disk or the second active combination disk under the action of magnetic force because the limiting snap spring is not limited with the sliding sleeve, so that the friction between the poking clamp and the first active combination disk or the second active combination disk is avoided.

Furthermore, the first driving roller is positioned on the outer side of a plate loading area of the temporary storage frame, and the plate loading area is a longitudinal projection area of the plate on the temporary storage frame.

Furthermore, one side of the temporary storage frame close to the plate conveying frame is provided with at least one first idle conveying roller, and one side of the plate conveying frame close to the temporary storage frame is provided with at least one second idle conveying roller.

Furthermore, the plate conveying frame is longitudinally connected to the rack in a sliding manner through a lifting mechanism.

The selection of the lifting mechanism is various and will not be described herein.

Furthermore, the inner side of the first active combination disk and the inner side of the second active combination disk are respectively provided with a movable disk which is rotatably connected to the sliding sleeve, and the poking clamp is arranged between the two movable disks.

The basic principle of the scheme is as follows: one of them defeated grillage accepts back alternative transport to a certain height with certain panel and keeps in the frame on, and another defeated grillage also can select the panel on the frame of keeping in of a certain height to take out, plays and accepts the effect and the effect of keeping in the panel production line, ensures the continuity of production line.

The difficulties of the above actions are: how are a plurality of, and typically tens, of boards fed from a conveying rack having a power source? How can a plate conveying rack with a power source take out a plate on a temporary storage rack without the power source? In this scheme, set up the contact-free clutch mechanism between defeated board frame and the frame of keeping in, make only under the prerequisite that sets up the power supply on defeated board frame, can make defeated board frame can transmit power to a certain with its layer keep in on the frame, and then make the entering that panel on the defeated board frame can be steady keep in the frame, perhaps keep in that panel on the frame can go out the board to defeated board frame.

However, defeated grillage is longitudinal movement in the frame, traditional clutch is because need the contact, and this scheme is not adapted, be the longitudinal movement that the contact combines to cause defeated grillage easily and hinder on the one hand, easily form card machine and trouble, on the other hand, the surface treatment who relates to multiple panel in the course of working of PCB board, and the temporary storage machine also often takes on the dry role of panel surface temporary storage, contact clutch must lead to the fact the dust because of the friction, these dusts not only pollute panel, but also can permeate in the transmission clearance of each driving medium, cause the problem that maintenance cycle is short, the fault rate is high.

The clutch mode in this scheme is the non-contact clutch mode, can overcome above-mentioned defect, specifically: when the plate conveying frame is translated to be level with a certain temporary storage frame and is suspended, the air cylinder pushes the sliding sleeve to move to one side close to the temporary storage frame, so that the first active combination disc is close to the first combination disc, but the first active combination disc and the second permanent magnet are not contacted, and the first permanent magnet and the second permanent magnet have larger adsorption force when being aligned and staggered, so that the power on the second transmission roller can be transmitted to the first transmission roller, each second conveying roller can rotate, the plate can enter the temporary storage frame from the plate conveying frame, and the plate can also be translated to the plate conveying frame from the temporary storage frame; when the second driving roller on the temporary storage frame does not need to be controlled to rotate, namely, when power is not required to be transmitted to the temporary storage frame, the air cylinder control sliding sleeve moves towards the inner side of the second driving roller, the second active combination disc is close to the second combination disc, the adsorption force between the third permanent magnet block and the fourth permanent magnet block is increased when the second active combination disc and the second combination disc are close to each other, the adsorption force is reduced after the first permanent combination disc and the first active combination disc are mutually far away, the power on the second driving roller can not be transmitted to the first driving roller, and the first permanent magnet block and the second permanent magnet block are in a separation state.

Because the width of the shifting clamp in the axial direction of the sliding sleeve is smaller than the width of the clamping groove, the shifting clamp is not contacted with the first active combination disc and the second active combination disc at the same time, friction is reduced, and because a gap is formed between the shifting clamp and the bottom of the clamping groove, the shifting clamp is not contacted with the bottom of the clamping groove, and the friction between the shifting clamp and the bottom of the clamping groove is avoided.

Because first combination roller and second combine the roller all to be located the periphery of defeated board district, because of dialling the dust that pincers and initiatively combine the friction that the contact of dish one or initiatively combine the dish two to cause and produce can not pollute the panel on defeated grillage or the frame of keeping in, and it keeps away from the transmission region, the influence of dust to the fit clearance of drive disk part is also less, of course, this part friction also can eliminate, for example: two movable discs which are rotatably connected to the sliding sleeve are arranged on the inner sides of the first active combination disc and the second active combination disc, a clamping groove is formed between the two movable discs, and the shifting clamp is also positioned between the two movable discs, so that the abrasion can be avoided.

Whether the first permanent magnet block corresponds to the second permanent magnet block or not does not influence the transmission of the first permanent magnet block and the second permanent magnet block, and the magnetic force of the permanent magnets has a certain distribution range, so that flexible connection can be realized between the first active combination disc and the first combination disc, and power transmission is realized. Of course, if it is possible to have a one-to-one correspondence, the reliability of the transmission power is better, but the jitter of the first transmission roller is also relatively large.

In order to avoid panel to get into the frame of keeping in or get into and keep in relatively steady when putting up, can not cause the condition of panel tip perk, establish first idle driving roller on the frame of keeping in of first driving roller both sides, set up the idle roller of second on the frame of conveying of second driving roller both sides, make panel can not receive the effect of power in the edge of traffic direction, make panel get into to keep in the frame at the frame of conveying and just receive the traction of the first driving roller on the frame of keeping in after having certain length, also make panel get into the traction that just receives the second driving roller on the frame of conveying after having certain length on keeping in the frame, especially be under first driving roller and second driving roller are intermittent type nature driven condition, avoid panel limit portion to receive traction force and can prevent panel limit portion perk, and then improve the stationarity when panel switches the platform, prevent that panel from blocking because of limit portion perk.

In conclusion, the scheme can greatly avoid friction generated in the process of transmitting power from the plate conveying frame to the temporary storage frame, avoid dust generation, improve the reliability of transmission parts and have long maintenance period; moreover, due to the adoption of the contact-free clutch mechanism, the gap between the plate conveying frame and the temporary storage frame can be relatively small, the plate is smoothly transferred, and the size of the temporary storage machine is smaller; the temporary storage frames do not need power mechanisms, and power is automatically transferred to the corresponding temporary storage frames when the plate conveying frames are leveled with the temporary storage frames, so that the structure is simplified, a plurality of power mechanisms originally existing on each temporary storage frame are eliminated, and the connection between the plate conveying frames and the temporary storage frames is more efficient, intelligent and reliable so as to adapt to efficient production and processing; finally, because each frame of keeping in all need not power unit, the vertical superpose clearance that makes the frame of keeping in can reduce, the vertical stroke of defeated grillage also can shorten, can increase substantially the quantity of keeping in the frame, several times traditional frame quantity of keeping in has very big promotion to the ability of temporary storage machine at commonality, the high-efficient intelligent production line of adaptation, under the condition of same overall height, this temporary storage machine can be kept in by 20 layers originally at least and put up the promotion to 50 ~ 60 layers.

The basic principle of the scheme is as follows: one of them defeated grillage 31 accepts back alternative transport to a certain height with certain panel on the frame 21 of keeping in, another defeated grillage 31 also can select the panel on the frame 21 of keeping in of a certain height to take out, plays and accepts effect and temporary storage effect in the panel production line, ensures the continuity of production line.

The difficulties of the above actions are: how are a plurality of, and typically tens of, buffer racks 21, a sheet material fed from a sheet conveying rack 31 having a power source into the buffer racks 21? How can the board conveying rack 31 with a power source take out the board on the temporary storage rack 21 without a power source? In this scheme, set up the contact-free clutch mechanism between defeated board frame 31 and the frame of keeping in 21, make only under the prerequisite that sets up the power supply on defeated board frame 31, can make defeated board frame 31 can be with power transmission to a certain with its flat bed keep in frame 21 on, and then make the board on defeated board frame 31 can be steady get into and keep in frame 21, perhaps keep in the board on the frame 21 and can go out the board to defeated board frame 31 on.

However, the board conveying frame 31 is longitudinally moved on the frame 1, the conventional clutch needs to be contacted, and is not suitable for the scheme, on one hand, the contact combination easily causes the longitudinal movement of the board conveying frame 31 to obstruct, the card jamming and the failure are easily formed, on the other hand, the surface treatment of various boards is involved in the processing process of the PCB board, the temporary storage machine also often plays the role of temporarily storing and drying the surfaces of the boards, the contact clutch inevitably causes dust due to friction, the dust not only pollutes the boards, but also permeates into the transmission gaps of transmission parts, and the problems of short maintenance period and high failure rate are caused.

The clutch mode in this scheme is the non-contact clutch mode, can overcome above-mentioned defect, specifically: when the board conveying frame 31 is translated to be leveled with a certain temporary storage frame 21 and is suspended, the air cylinder 47 pushes the sliding sleeve 43 to move to one side close to the temporary storage frame 21, so that the first active combination disc 44 is close to the first combination disc 41, but the first active combination disc 44 and the second active combination disc 41 are not contacted, and the first permanent magnet 51 and the second permanent magnet 52 have larger adsorption force when being misaligned in the positive-to-negative direction, so that the power on the second transmission roller 33 can be transmitted to the first transmission roller 23, and further, each second conveying roller 32 is rotated, the board can enter the temporary storage frame 21 from the board conveying frame 31, and the board can also be translated to the board conveying frame 31 from the temporary storage frame 21; when the second driving roller 33 on the temporary storage frame 21 does not need to be controlled to rotate, that is, power does not need to be transmitted to the temporary storage frame 21, the air cylinder 47 controls the sliding sleeve 43 to move towards the inner side of the second driving roller 33, so that the second active combination disc 45 is close to the second combination disc 42, and because the adsorption force between the third permanent magnet block 53 and the fourth permanent magnet block 54 is increased when the second active combination disc 45 and the second combination disc 42 are close to each other, and the adsorption force is reduced after the first combination disc 41 and the first active combination disc 44 are far away from each other, the power on the second driving roller 33 cannot be transmitted to the first driving roller 23, that is, the two are in a separated state.

Because the width of the poking pincers 48 in the axial direction of the sliding sleeve 43 is smaller than the width of the clamping groove 46, the poking pincers 48 are not contacted with the first active combination disk 44 and the second active combination disk 45 at the same time, friction is reduced, and because a gap is formed between the poking pincers 48 and the bottom of the clamping groove 46, the poking pincers 48 are not contacted with the bottom of the clamping groove 46, and friction between the poking pincers 48 and the clamping groove 46 is avoided.

Because the first combination roller and the second combination roller are both located at the periphery of the board conveying area, dust generated by friction caused by contact between the poking pincers 48 and the first active combination disk 44 or the second active combination disk 45 cannot pollute the boards on the board conveying frame 31 or the temporary storage frame 21, and the dust is far away from the transmission area, so that the influence of the dust on the fit clearance of the transmission part is small, and of course, the friction can be eliminated, such as: two movable discs which are rotatably connected to the sliding sleeve 43 are arranged on the inner sides of the first active combination disc 44 and the second active combination disc 45, a clamping groove 46 is formed between the two movable discs, and the poking pincers 48 are also positioned between the two movable discs, so that the abrasion can be avoided.

Whether the first permanent magnet 51 and the second permanent magnet 52 correspond to each other or not does not affect the transmission of the permanent magnets, and the magnetic force of the permanent magnets has a certain distribution range, so that the first active combination disc 44 and the first combination disc 41 can be flexibly connected, and power transmission is realized. Of course, if it can be in one-to-one correspondence, the reliability of the transmission power is better, but the jitter of the first transmission roller 23 is also relatively large.

In order to avoid the situation that the end of the plate is tilted when the plate enters the plate conveying frame 31 or the temporary storage frame 21, the temporary storage frames 21 on both sides of the first transmission roller 23 are provided with a first idle transmission roller, the plate conveying frames 31 on both sides of the second transmission roller 33 are provided with a second idle roller, so that the edge of the plate in the running direction can not be influenced by power, the plate is pulled by the first transmission roller 23 on the temporary storage frame 21 after the plate conveying frame 31 enters the temporary storage frame 21 for a certain length, the plate is also pulled by the second transmission roller 33 on the plate conveying frame 31 after the plate enters the plate conveying frame 31 for a certain length on the temporary storage frame 21, especially under the condition that the first transmission roller 23 and the second transmission roller 33 are both in intermittent transmission, avoid panel limit portion to receive traction force can prevent the perk of panel limit portion, and then improve the stationarity of panel when switching the platform, prevent that panel from blocking because of limit portion perk.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
