Description

Technical Field

[0001] The invention relates to the technical field of stationery production, and in particular to an automated production line for compasses. Background Art

[0002] In mathematics and drawing, a compass is a tool used to draw circles or arcs, and is often used in ruler and compass drawing. A compass usually consists of a lead foot that can accommodate the lead core and a pin that accommodates the positioning pin. The upper ends of the lead foot and the pin are connected together by a fork that can be opened and closed. When in use, the pin is fixed to a plane, and the lead foot can be rotated along the pin to form an arc or circle on the plane. When the compass is being processed, the lead foot is inserted into the lead core and the pin is inserted into the fixing pin. After then being transported, the lead foot and the pin are manually combined through the fork.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: in the existing compass production process, the pin feet and the lead feet need to be processed separately, and after processing, they need to be manually transported to the assembly workshop for manual processing and assembly.

[0016] The present invention feeds the pins into the fixed disk through the pin positioning groove, rotates the fixed handle to squeeze one side of the pin and presses the other side of the pin against the rubber column to fix the pin. At the same time, the pressure fixing block on the pressure handle is used to buffer the extrusion force, and after absorbing the excessive pressure on the pin, the suction force is used to further improve the fixing effect of the pin, thereby preventing the pin from being squeezed and skewed during the processing and reducing the rejection rate after processing.

[0017] The present invention uses the lead core fixing ring and the clamping machine to inwardly squeeze and fix the lead core. After the lead core is loaded, the one-way bump can be used to make the lead core rotate clockwise and be stuck when rotating counterclockwise.

At the same time, when the clamping force is applied to the lead core, the block body and the deformable airbag can be used to disperse and absorb the clamping force, avoiding excessive clamping force from breaking the lead core and effectively reducing the rejection rate during processing.

A plurality of fastening force-receiving blocks 44 are provided on the outer wall of the pressure outer ring 41, and a plurality of inwardly retracting deformation grooves 43 penetrate through the outer wall of the pressure outer ring 41. On the other side of the lead leg processing table 6, there is a lead leg transfer table 2 connected to the lead leg processing table 6. Above the lead leg processing table 6, there is also a fork head assembly table 7. On one side of the fork head assembly table 7, there is a fork head transfer table 3 connected to the fork head assembly table 7. Above the pin processing table 5 and on one side of the fork head assembly table 7, there is an overall assembly table 8. On one side of the overall assembly table 8, there is a finished product output table 4 connected to the overall assembly table 8. The pins are sent into the pin processing table 5 through the pin transfer table 1 to connect the pins. The lead legs are sent into the lead leg processing table 6 through the lead leg transfer table 2 for lead core insertion. The fork heads are sent onto the fork head assembly table 7 through the fork head transfer table 3 for fork head assembly. Subsequently, the fork heads, pins, and lead legs are assembled on the overall assembly table 8 and the finished products are output from the finished product output table 4. When in use, the lead leg processing table 6, the pin processing table 5, the fork head assembly table 7, and the overall assembly table 8 are combined and placed in the same position. The lead legs, pins, fork heads, and finished products are automatically fed in and out through the lead leg transfer table 2, the pin transfer table 1, the fork head transfer table 3, and the finished product output table 4. Only a few personnel are required to operate the entire production line, with a high degree of automation. There is no need for manual handling of various parts, and the processing efficiency is high. When performing pin processing, the pins transferred from the pin transfer table 1 are placed into the pin positioning grooves 562 on the fixed disk 561 so that they are aligned with the edges of the pin positioning grooves 562. At the same time, by adjusting the position of the rubber column 565 in the adjustment groove 566, the pins can be better aligned with the pin positioning grooves 562. Subsequently, the torque motor 22 is started, causing the torque motor 22 to drive the connecting sleeve 231 of the pressure handle 23 to rotate, thereby synchronously driving the swing handle 232 and the pressure fixing block 235 provided at its bottom to move, and causing the pressure fixing block 235 to press against the pins, making the adsorption holes 34 align and fit on the surface of the pins. This causes the rubber block 31 to deform, and then the compression cavity 32 inside it is squeezed and the air inside it is pushed out through the exhaust pipe 33. The air pressure will cause the closing piece 36 to be twisted, thereby losing its effect of closing the exhaust pipe 33. At the same time, when the air flow reverses, it will be pushed up again to restore the closing of the exhaust pipe 33. Thus, a pressure difference is generated between the inside and outside of the compression cavity 32, and then the position of the adsorption holes 34 generates suction due to the internal and external pressure difference, and the adsorption range is expanded in cooperation with the enlarged holes 37. At this time,After absorbing excessive pressure on the pins, the suction force can be used to further improve the fixing effect on the pins, thereby preventing the pins from being squeezed and skewed during processing, reducing the scrap rate after processing. Subsequently, align the pins with the needle loader 52, then insert the needles into the pins, and select and drill the first rotating disk 54 to rotate the pins with inserted needles into the needle nut lock 55. Lock the nut of the pin to fix the needle through the needle nut lock. Subsequently, continue to rotate the first rotating disk 54 to bring it to the position of the pin extractor 53. Use the pin extractor 53 to remove the processed pins and place them on the general assembly table 8 for general assembly preparation. When processing the lead feet, use the lead foot conveyor 2 to send the lead feet to the lead foot processing table 6 and send them into the lead foot pusher 62, with the end that needs to be loaded with the lead core facing the second rotating disk 63. At the same time, put a batch of lead cores into the lead core storage 65, so that the lead core storage 65 can lift the lead cores and can be manually loaded into the lead core fixing ring 644 of the lead core fixer 64 provided on the second rotating disk 63. At the same time, start the clamping machine 643 to output the clamping force to the clamping force receiving block 44, so that the pressure outer ring 41 drives the contact block 42 to contract inward along the inward deformation groove 43, and finally make the inner cavity gap between the contact blocks 42 the same as the size of the lead core. At this time, the lead core can be rotated and loaded into the inner cavity formed by the contact blocks 42, and it generates frictional force with the block body 421 of the contact block 42 through the friction groove 422 to prevent sliding. Subsequently, rotate the second rotating disk 63 to drive the lead core fixer 64 to the position of the lead foot pusher 62 where the lead feet are placed. Then, push out the lead feet through the lead foot pusher 62, and drive the clamping machine 643, the lead core fixing ring 644 and the lead core to rotate through the rotating machine 642 and screw the lead core into the lead foot through rotation. During the rotation process, cooperate with the extrusion force generated by the clamping machine 643 to fully fix the lead core. At the same time, when the clamping force is applied to the lead core, the silicone material block body 421 and the deformation airbag 424 can be used to disperse and absorb the clamping force to avoid breaking the lead core due to excessive clamping force. The fiber layer 425 and the elastic fiber filaments 426 make the deformation amplitude of the deformation airbag 424 more controllable, avoiding the protrusion of the block body 421 and squeezing the lead core. At the same time, when screwing in the lead core, when the lead core has a tendency to rotate counterclockwise during the screwing process, the friction groove 422 and the one-way convex block 423 can be used to fully prevent the lead core from rotating, preventing it from twisting during the loading process and resulting in an insecure fixation phenomenon, effectively reducing the scrap rate generated during processing. The lead feet with inserted lead cores can be taken out from the lead foot pusher 62, collected and placed on the nearby general assembly table 8, and the fork head components output from the fork head transfer table 3 are assembled on the fork head assembly table 7. Subsequently, the lead feet and pins can be inserted into the fork head on the general assembly table 8, and the finished products are output through the finished product output table 4. Only 4-5 people are required to operate the entire production line, which is very labor-saving and greatly improves the processing speed.

[0022] A plurality of receiving grooves 10 are provided on the transmission belts of the pin transfer table 1, the lead pin transfer table 2, the fork head transfer table 3 and the finished product output table 4, which is beneficial to putting pins, lead pins, fork heads and finished products into the receiving grooves 10, avoiding detachment from the transmission belt during transmission, and making the transmission more stable; The top end of the rotating shaft of the torsion motor 22 is meshed with the tightening bolt 24 of the extrusion pressure handle 23, which is beneficial to adjusting the connection firmness of the pressure handle 23 through the tightening bolt 24. When lower torque is required, the tightening bolt 24 can be loosened, and then the pressure handle 23 can be twisted within a small range to obtain a better buffering effect.

[0023] Working principle of the present invention: When the present invention is in use, the lead pin processing table 6, the pin processing table 5, the fork head assembly table 7 and the general assembly table 8 are combined and placed in the same position. The lead pins, pins, fork heads and finished products are automatically fed in and out through the lead pin conveyor 2, the pin conveyor 1, the fork head conveyor 3 and the finished product output table 4. Only a few personnel are required to operate the entire production line, with a high degree of automation, no need for manual handling of various parts, and high processing efficiency. When processing the pins, the pins conveyed from the pin conveyor 1 are placed into the pin positioning grooves 562 on the fixed disk 561 to align them with the edges of the pin positioning grooves 562. At the same time, by adjusting the position of the rubber posts 565 in the adjustment grooves 566, the pins can be better aligned with the pin positioning grooves 562. Then, the torque motor 22 is started, causing the torque motor 22 to drive the connecting sleeve 231 of the pressure handle 23 to rotate, thereby synchronously driving the swing handle 232 and the pressure fixing block 235 provided at its bottom to move, and making the pressure fixing block 235 press against the pins in contact, so that the adsorption holes 34 are aligned and fitted to the surface of the pins. This causes the rubber block 31 to deform, and then the compression cavity 32 inside it is squeezed and the air inside it is pushed out through the exhaust pipe 33. The air pressure causes the closing piece 36 to be twisted, thereby losing its effect of closing the exhaust pipe 33. At the same time, when the air flow reverses, it will be pushed up again to restore the closing of the exhaust pipe 33. Thus, a pressure difference is generated between the compression cavity 32 and the outside world, and then the position of the adsorption holes 34 generates suction due to the internal and external pressure difference, and the adsorption range is expanded in cooperation with the enlarged holes 37. At this time, after absorbing the excessive pressure on the pins, the suction force can be used to further improve the fixing effect on the pins, thereby preventing the pins from being squeezed and skewed during the processing and reducing the rejection rate after processing. Then, the pins are aligned with the needle head loader 52, and then the needle heads are loaded into the pins. Then, the first rotating disk 54 is rotated to select and drill so that the pins with the loaded needle heads are rotated into the needle head nut lock 55, and the nut of the pins is locked by the needle head nut lock to fix the needle heads. Then, the first rotating disk 54 can be continuously rotated to make it reach the position of the pin extractor 53, and the processed pins are taken out by the pin extractor 53 and placed on the general assembly table 8 for general assembly preparation. When processing the lead pins, the lead pins are fed onto the lead pin processing table 6 through the lead pin conveyor 2, and the lead pins are fed into the lead pin inner pusher 62, with the end that needs to be loaded with the lead core facing the second rotating disk 63. At the same time, a batch of lead cores are placed in the lead core storage 65, and the lead core storage 65 can lift the lead cores and can be manually loaded into the lead core fixing rings 644 of the lead core fixers 64 provided on the second rotating disk 63. At the same time, the clamping machine 643 is started to output the clamping force to the buckling force receiving block 44, so that the pressure outer ring 41 drives the contact blocks 42 to contract inward along the inward deformation groove 43, and finally the inner cavity gap between the contact blocks 42 is the same as the size of the lead core. At this time, the lead core can be rotated and loaded into the inner cavity formed by the contact blocks 42.And make it generate frictional force between the contact block 42 and the block body 421 of the contact block 422 through the friction groove to prevent sliding. Subsequently, the second rotating disk 63 can be rotated to drive the lead core holder 64 to the position of the lead foot inner pusher 62 for placing the lead foot. Then, the lead foot is pushed out by the lead foot inner pusher 62, and the clamping machine 643, the lead core fixing ring 644 and the lead core are driven by the rotating machine 642 to rotate, and the lead core is screwed into the lead foot through rotation. During the rotation process, the squeezing force generated by the clamping machine 643 is used to fully fix the lead core. At the same time, when the clamping force is applied to the lead core, the block body 421 made of silica gel material can cooperate with the deformation airbag 424 to disperse and absorb the clamping force, avoiding breaking the lead core due to excessive clamping force. The fiber layer 425 and the elastic fiber wire 426 make the deformation amplitude of the deformation airbag 424 more controllable, avoiding the protrusion of the block body 421 to squeeze the lead core. At the same time, when screwing in the lead core, when the lead core has a tendency to rotate counterclockwise during the screwing process, the friction groove 422 and the one-way convex block 423 can be used to fully prevent the lead core from rotating, preventing it from twisting during the loading process and resulting in insecure fixation, effectively reducing the waste rate generated by processing. The lead foot after loading the lead core can be taken out from the lead foot inner pusher 62, collected and placed on the nearby general assembly table 8, and the fork head components output from the fork head transfer table 3 are assembled on the fork head assembly table 7. Subsequently, the lead foot and the pin can be loaded into the fork head on the general assembly table 8, and the finished product is output through the finished product output table 4. Only 4-5 people are required to operate the entire production line, which is very labor-saving and greatly improves the processing speed.
