[0002] Ceramic circuit boards are widely used in medical, automotive electronics, communications, aerospace, power modules and other fields due to their high thermal conductivity, fast heat dissipation and good insulation. Ceramic circuit boards are usually copper-clad on the surface, and in order to facilitate the electrical signal connection between the ceramic circuit board and external components, pins are usually extended outward, such as Figure 1 As shown, welding is usually used, but the bonding strength of the ceramic circuit board 1' is low, which makes it easy for the pin 2' to fall off; therefore, a method is proposed to use a needle-threading method to pass the copper wire through the through hole of the ceramic circuit board, and then use an extrusion method to press one end of the copper wire on the ceramic circuit board to achieve fixation. However, the holes in the ceramic circuit board are very small. If manual operation is used, the production efficiency is low, which increases the production cost in disguise.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] Please refer to Figure 2-14 ;

[0040] The pin insertion machine described in the present invention is intended to realize automatic pin insertion production of ceramic circuit boards and improve work efficiency; the "needle" described in the part of the invention is a metal wire with a certain toughness, such as a copper wire, which can be wound on a roller 551 before use. After being guided out and straightened, the metal wire can maintain a straight state, that is, forming a "needle"; the device specifically includes a wire guide device 1, a wire insertion device 2, a wire cutting device 3 and a plate feeding device 4 installed from top to bottom, and a roller pressing device 5 is installed on one side of the plate feeding device 4; it should be noted that a storage device 6 for storing wire materials is also installed outside the device. In the initial state, the wire materials are stored in a coil in the storage device 6, and the wire materials output from the storage device 6 enter the wire guide device 1;

[0041] During operation, the wire is first guided into the cutting device 3 in a straight state through the guide wire device 1, and maintaining the straight shape of the wire is the basis for the subsequent formation of the pin; the wire introduced therein is then cut by the cutting device 3, and separated from the wire to form a wire segment located in the cutting device 3. In this process, the end of the wire segment is also flattened so that the width of the flattened part is slightly larger than the width of the original diameter of the wire segment cross section. Of course, the end referred to here can also be a position close to the end; in the process of cutting the wire, the plate feeding device 4 sends the plate to the designated position so that it is below the cutting device 3 and corresponds to the wire segment. A number of holes are provided on the plate for the wire segment to pass through. In order to be able to more accurately pass the wire segment through the holes on the plate, a number of channels corresponding to the wire segment are also provided on the cutting device 3. Under the movement of the plate feeding device 4, The end face of the plate is close to the bottom face of the cutting device 3, so that the hole on the plate is aligned with the outlet of one end of the channel, and then the cutting device 3 releases the wire segment so that it can pass through the channel and be inserted into the hole of the plate at the same time. However, the process of the wire segment passing through the channel is affected by friction and may get stuck. At the same time, the other end of the wire segment is flat, which also makes it impossible for the wire segment to pass through the channel smoothly. At this time, the wire insertion device 2 is actuated, and the pin on the wire insertion device 2 can pass through the channel and press against the end of the wire segment, pushing the wire segment out of the channel and inserting it into the hole of the plate, while the flat end of the wire segment cannot pass through the hole of the plate, so that the wire segment hangs on the plate, and finally the plate is taken out by the rolling device 5, and the flat end of the wire segment is flattened by rolling and pressing, and the flattened end fits against the end face of the plate, so that the wire segment is fixed to the plate, that is, forming a pin on the plate. Figure 14 This is a schematic diagram of one end of the line segment being flattened, which is the final state after the processing is completed.

[0042] It should be noted that the above-mentioned plate is composed of several ceramic circuit boards. The holes on the ceramic circuit boards are very small. The machine needs to form at least one pin for each ceramic circuit board. The wire device 1 can introduce several wires at the same time as needed, and form multiple pins on the plate at the same time. There is no need to operate one by one, which improves production efficiency. Of course, the number of wires to be introduced can also be selected within a limited range according to production needs, making equipment production more flexible.

[0043] The automatic pin insertion machine for ceramic sheets described in the present invention can complete the pin insertion operation for tiny holes in ceramic circuit boards, and completes the formation of one or more pins through a series of actions, thereby realizing automated production, greatly improving production efficiency, and reducing production costs. The number of pins can also be selected according to product needs, thereby improving the flexibility of the equipment.

[0044] One embodiment of the present invention regarding the wire guide device 1 is shown in FIG. Figure 4 and Figure 5 The wire guide device 1 is used to convert the input wire rods into a vertical direction. Specifically, it includes a fixed plate 11. A longitudinally arranged wire wheel group 12 is installed on one side of the fixed plate 11. The wire wheel group 12 in this embodiment is composed of a plurality of wire wheel groups 12. A plurality of wire grooves are provided on the surface of the wire wheel. For example, the wire rod is input horizontally and then placed in the wire groove and wound on the uppermost wire wheel, so that the wire rod input horizontally is bent 90 degrees to form a vertical state. The wire rod is prevented from deflecting by the wire groove. Of course, the plurality of wire wheels can be staggered so that the wire rod can be better maintained in a vertical state when introduced. A movable plate 13 is provided below the wire pulley assembly 12, which is slidably connected to the fixed plate 11. A cylinder 14 is installed on the opposite side of the movable plate 13. The cylinder 14 is connected to the movable plate 13 through a bracket, that is, the cylinder 14 can move with the movable plate 13. A pressure block 15 is provided at the output end of the cylinder 14 and the end face of the movable plate 13. The end face of the pressure block 15 in this embodiment can be made of a soft material. When the two pressure blocks 15 are pressed together, damage to the surface of the wire can be avoided. A cylinder 2 16 is longitudinally installed on the other side of the fixed plate 11, and the output end of the cylinder 2 16 is connected to the movable plate 13.

[0045] In the initial state, a number of wires are converted into a vertical state through the wire wheel assembly 12 and placed between the two pressing blocks 15. Of course, the wires output by the wire wheel assembly 12 should be close to the end face of the pressing block 15 located at the movable plate 13 to avoid the position of the wires being offset when the two pressing blocks 15 are pressed together. When the wires need to be introduced into the cutting device 3, the cylinder 14 is actuated to drive one of the pressing blocks 15 to move closer to the other pressing block 15 until they are pressed together. Then the cylinder 2 16 is started and extended downward to drive the movable plate 13 to move downward. Since the wires have been compressed, they will drag the wires downward together, so that the wires are introduced into the cutting device 3. Then the cylinder 14 retracts to separate the two pressing blocks 15. After that, the cylinder 2 16 retracts to drive the movable plate 13 to move upward and reset.

[0046] The corresponding processing device for storing wire does not need to be equipped with a power device. The wire can be output by pulling the wire device 1, which simplifies the structure of the storage device 6. In addition, a magnetic induction device 7 is provided between the storage device 6 and the equipment of the present invention. The magnetic induction device 7 is provided with several induction positions. The wire derived from the storage device 6 must pass through the induction position. When the wire device 1 is pulled to pull the wire to move, an induction signal will be generated. In this way, it can be determined that there is still wire at this position. When the magnetic induction signal disappears, it means that the required wire is about to run out. It should be noted that the magnetic induction device 7 is at a certain distance from the wire device 1. Even if the magnetic induction signal disappears, the remaining wire is sufficient to complete several operations, so that the staff has sufficient time to change materials.

[0047] The storage device 6 of the present invention can store up to 18 rolls of material, that is, it can output 18 wires at a time. Figure 3 However, the output angles of the eighteen wires are all different. In order to facilitate the output of several wires in the same direction before they are input into the wire device 1, a wire member 8 is provided between the magnetic induction device 7 and the wire device 1. The wire member 8 is provided with two rows of horizontally straight through holes for the wires to pass through, so that the output angle of the same wire is the same, and the through holes correspond to the wire grooves.

[0048] One embodiment of the cutting device 3 of the present invention is shown in FIG. Figure 6 and Figure 7 , specifically including a fixing base 311, the fixing base 311 is provided with a plurality of jacks 312 for the wire segments to pass through, and the wire insertion device 2 also corresponds to the jacks 312. The plurality of jacks 312 in this embodiment are distributed in a straight line at intervals, and a cylinder three 321 and a cylinder four 331 are installed on opposite sides of the jacks 312. A lower cutter 323 is provided at the output end of the cylinder three 321, and a plurality of cutting holes 324 for the wires to pass through are provided on the lower cutter 323. An upper cutter 322 is fixed above the lower cutter 323, and a pressing knife 332 is provided at the output end of the cylinder four 331. The end face of the pressing knife 332 is provided with a pressing edge 333, and the pressing edge 333 can be against the end face of the lower cutter 323;

[0049] When the wire is working, the wire is driven downward by the wire guide device 1, and the wires are synchronously inserted into the cutting holes 324 where the lower cutter 323 is located. Then, the cylinder 321 is actuated to push the lower cutter 323 and the upper cutter 322 relative to each other, so that the two form a shearing action to cut the wire. It should be noted that the cutting holes 324 are arranged near the ends of the cutter, so the lower cutter 323 and the upper cutter 322 can cut the wire with a slight misalignment. After the wire is cut, the cylinder 321 continues to move toward the insertion hole 312. At the same time, the cylinder 4 331 is actuated to push the pressing knife 332 toward the lower cutter 323. It should be noted that the cutting holes 324 are below the end surface of the fixing seat 311, so the wire segments formed in the cutting holes 324 after being cut will fall slightly and contact the end surface of the fixing seat 311; of course, they may also be prevented from falling due to friction, but this does not affect the subsequent actions.

[0050] Finally, the lower cutter 323 and the pressing knife 332 collide at the insertion hole 312. At this time, the cutting hole 324 corresponds to the insertion hole 312 above and below. The pressing edge 333 presses against the end surface of the lower cutter 323 to squeeze the ends of the plurality of line segments, flattening the ends of the line segments. In this embodiment, a groove 325 is provided on the side of the lower cutter 323 close to the pressing knife 332 to adapt to the pressing edge 333. Figure 8 and Figure 9 When the wire passes through the cutting hole 324, it also passes through the groove 325. The portion of the wire that passes through the groove 325 will be exposed. When the pressing edge 333 fits into the groove 325, the portion of the wire segment will be flattened. Of course, the width of the flattened portion is only slightly larger than the width of the other portion, so it can still pass through the cutting hole 324.

[0051] The above is only one of the operating methods of the lower cutter 323 and the pressing knife 332. For example, if the two do not meet at the insertion hole 312, it is also possible to move to the insertion hole 312 after flattening the line segment; in addition, in order to make the movement of the lower cutter 323 and the pressing knife 332 more stable, a limiting slide groove 313 can be set on the fixed seat 311.

[0052] After partially flattening the line segment, the cylinder 4 331 drives the pressing knife 332 to retract and separate the pressing knife 332 from the lower cutting knife 323. Based on the above-mentioned cutting hole 324 being slightly larger than the diameter of the line segment, the line segment formed in the cutting hole 324 may be tilted and not vertical. Therefore, the operation of using the pressing knife 332 to flatten the line segment is not only a subsequent process requirement, but also can straighten the state of the line segment in the cutting hole 324 during the contact between the pressing edge 333 and the line segment, so that the line segment is uniformly vertical, which is convenient for the subsequent operation of passing through the insertion hole 312.

[0053] The socket 312 in this embodiment has a certain length, corresponding to the channel in the above scheme, that is, the aperture of the socket 312 is also slightly larger than the width of the flattened position of the wire segment. After the end is squeezed, the wire segment will not fall into the socket 312 on its own due to the friction force. At this time, the wire insertion device 2 is started to push the wire segment into the socket 312 through the cutting hole 324.

[0054] Reference Figure 6 The wire insertion device 2 in this embodiment includes a mounting base 21, and the mounting base 21 is provided with a driving component 22. The output end of the driving component 22 is equipped with a plurality of thimbles 23 that can be inserted into the cutting hole 324. The driving component 22 drives the thimbles 23 to move downward, so that the thimbles 23 enter the cutting hole 324 and push the wire segment into the socket 312. Of course, the length of the thimbles 23 can also be lengthened so that the thimbles 23 can extend to the socket 312.

[0055] In this embodiment, the plate can be placed close to the fixing seat 311 so that the through hole on the plate is aligned with the other end of the insertion hole 312, and the line segment can enter the through hole of the plate after the ejector pin 23 pushes it out.

[0056] Further, refer to Figure 11 A cover plate 351 is provided at the position of the upper cutter 322, and a plurality of wire holes 352 and a plurality of guide pin holes 353 are provided on the cover plate 351. The wire holes 352 correspond to the cross section of the upper cutter 322 in the vertical direction, and a semicircular groove 523 is provided on the end face of the upper cutter 322. The guide pin holes 353 correspond to the insertion hole 312. As long as the ejector pin 23 can pass through the guide pin hole 353, it can also pass through the cutting hole 324 and the insertion hole 312. The guide pin hole 353 improves the accuracy of the insertion of the ejector pin 23.

[0057] Since the hole on the plate is very small, which is basically the same as the diameter of the wire, it will be subject to friction during the insertion process. Therefore, it is necessary to use a pin 23 to push the wire segment into the hole of the plate. In order to further improve the accuracy of the pin 23, a guide assembly is provided at the bottom of the fixing seat 311. Figure 10 The guide assembly is provided with a guide hole 343. The diameter of the guide hole 343 is adapted to the line segment to avoid the problem of deviation. However, the flattened part of the line segment cannot pass through. To this end, there is a structure including two symmetrically mounted cylinders 341. The output ends of the two cylinders 341 are both equipped with movable plates 342. The two movable plates 342 are provided with semicircular grooves on opposite sides. The two semicircular grooves are combined to form the guide hole 343. The guide hole 343 corresponds to the bottom of the insertion hole 312, and the diameter of the guide hole 343 is smaller than the diameter of the insertion hole 312.

[0058] One implementation method is that, first, under the drive of the plate feeding device 4, the plate is brought close to the guide assembly, and the hole on the plate is aligned with the guide hole 343, and then the wire segment passes through the insertion hole 312 and enters the guide hole 343 under the push of the ejector pin 23. Since the aperture of the guide hole 343 is adapted to the wire segment, the wire segment will not be deviated and can accurately correspond to the hole of the plate, and pass through the guide hole 343 and insert into the hole where the plate is located. When the flattened part of the wire segment reaches the end of the guide hole 343, it will be blocked and unable to pass through, but at this time, part of the wire segment has passed through the guide hole 343 and inserted into the hole where the plate is located. Then, under the action of the two cylinders five 341, the two movable plates two 342 are driven to separate, and the guide hole 343 disappears to make enough space for the flattened part of the wire segment to pass through. At this time, the driving assembly 22 continues to push the wire segment, so that the wire segment continues to be inserted into the plate, and finally the flattened part of the wire segment stays on the end face of the plate.

[0059] Based on this embodiment, the ejector pin 23 has two downward extending actions, one to be inserted into the socket 312 and the other to be inserted into the guide hole 343. To this end, the driving component 22 uses two cylinders to complete the two actions respectively, including a longitudinally arranged cylinder 6 221. The output end of the cylinder 6 221 is equipped with a longitudinally arranged cylinder 7 222, and the ejector pin 23 is installed at the output end of the cylinder 7 222.

[0060] One embodiment of the plate loading device 4 of the present invention is shown in FIG. Figure 2 and Figure 12 , specifically including correspondingly installed storage components 41, loading and moving clamping components 42 and loading and transporting components 43, the loading and transporting components 43 extend to the roller pressing device 5, and a jig for placing the plate is provided on the loading and transporting components so that the plate holes are close to the guide holes 343; the plate is obtained from the storage component 41 by the loading and moving clamping components 42, and then placed on the jig, and the loading and transporting components 43 drive the jig to move to the bottom of the guide component so that the holes on the plate are close to the guide holes 343. After completing the line segment interlacing operation, the loading and transporting components 43 drive the jig to move to the roller pressing device 5 for the next operation;

[0061] Furthermore, the storage assembly 41 includes a storage rack 412 with at least two storage bins 411, the bottom of the storage rack 412 is slidably connected to a sliding pair 413, and one side of the storage rack 412 is connected to the output end of the cylinder eight 414, and an ejection mechanism 415 is installed below the storage rack 412, and the ejection mechanism 415 can be extended from the storage bin 411; plates are stacked longitudinally in the storage bin 411, and the plates in the storage bin 411 are pushed upward by the ejection mechanism 415, so that the plates are maintained at a height for easy loading and moving of the clamping assembly 42. When the plates in one of the storage bins 411 are used up, the storage rack 412 is driven by the cylinder eight 414 to slide along the sliding pair 413, so that the other storage bin 411 corresponds to the ejection mechanism 415.

[0062] The present invention relates to one embodiment of the roller pressing device 5, referring to Figure 13 , specifically including the corresponding installed unloading moving clamping component 51 and unloading transport component 521, the unloading moving clamping group obtains the plate located on the loading transport component 43 and transfers it to the unloading transport component 521, the unloading transport component 521 is slidably connected with connecting blocks 53 on both sides, the connecting blocks 53 are connected to the cylinder nine 54, and a roller 551 is provided between the two connecting blocks 53, and a pressure bar 1 552 and a pressure bar 2 553 are respectively provided along the circumference direction of the roller 551, wherein the pressure bar 1 552 is used to press the plate, and the pressure bar 2 553 corresponds to the flat head of the line segment; the unloading transport component 521 in this embodiment is provided with a slot 523 adapted to the plate to avoid deviation during rolling, and the line segments on the plate are distributed in a straight line, and the slot The two sides of position 523 are hollowed out so that the line segment can pass through when the plate is placed, and a pressure beam 522 is provided in the groove 523 along the direction of movement, and the pressure beam 522 corresponds to the pressure strip 1 552; during operation, the unloading and transportation component 521 pushes the plate to move forward, and at the same time, the cylinder nine 54 drives the connecting block 53 to slide in the opposite direction, and squeezes the plate through the pressure strip 1 552 to avoid jumping during rolling. At the same time, the setting of the pressure beam 522 avoids damaging the plate. It should be noted that the side of the groove 523 is also provided with a part that supports the plate, that is, there are three supporting positions at the bottom of the plate; the pressure strip 2 553 corresponds to the flat head of the line segment, flattens the protruding part and fits it to the end face of the plate, so that the line segment is fixed to the plate.
