Description

Technical Field

[0001] The invention belongs to the technical field of PCB milling cutter production, and relates to an automatic packaging device for PCB milling cutter production. Background Art

[0002] The milling cutter used for PCB is also called a milling cutter. It is used in the post-process of PCB (or pressing and catching the outer frame). The main purpose is to use this cutter to cut the manufactured circuit board into individual PCS or SPNL and then ship it to the customer. That is the product size that the customer ultimately requires. This cutter is mainly used for cutting. The blade and force direction are horizontal, similar to a drill needle, but the force and cutting direction of the drill needle are at the drill tip. There are two types of milling cutters: fishtail type and drill tip type. The special design focuses on the service life of the milling cutter and the chip removal effect. It is characterized by a large chip removal groove, which makes chip removal smooth, heat generation is low, and there are fewer stains on the hole wall during drilling;

[0003] After the PCB milling cutter is produced, it is usually inserted into a placement tray. In the packaging process, the operator needs to pull the PCB milling cutter from the placement tray, and then insert it into a placement board with a hole, and finally pack the placement board inside the packaging box. However, there are generally multiple holes on the placement board, and the operator's manual insertion speed is slow. In addition, the PCB milling cutter is generally small in size and can easily scratch the operator, further increasing the difficulty of operation for the operator. As a result, the operator spends a long time inserting the PCB milling cutter on the placement board, which reduces the packaging speed of the PCB milling cutter.

[0004] Based on this, we designed an automatic packaging device for PCB milling cutter production. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose an automatic packaging device for PCB milling cutter production. The technical problem to be solved by the device is: how to automatically insert the milling cutter on the placement tray onto the placement board to increase the packaging speed of the PCB milling cutter.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] An automatic packaging device for PCB milling cutter production comprises a first conveyor equipped with a first conveyor belt, a second conveyor equipped with a second conveyor belt, a placement tray and a placement plate, wherein the placement tray is placed on the first conveyor belt, the placement plate is placed on the second conveyor belt, and the first conveyor and the second conveyor are vertically distributed. A mounting plate is fixed on the frame of the first conveyor, an N-shaped groove is provided on the mounting plate, a movable plate is provided on one side of the mounting plate, and a driving mechanism for driving the movable plate to move along the N-shaped groove is provided on the other side of the mounting plate, a slide rail is fixed on the movable plate, and two symmetrically distributed sliding seats are slidably provided on the slide rail, a clamping rod for clamping the PCB milling cutter is fixed on the sliding seat, a clamping mechanism is provided between the two clamping rods, and a spacing adjustment mechanism is provided on the clamping rod, the second conveyor belt passes through the mounting plate, and the second conveyor belt is located directly below one end of the N-shaped groove, a limit rod is fixed on the side end of the mounting plate, and the limit rod is located above the first conveyor belt.

[0008] The working principle of the present invention is as follows: during the processing of the PCB milling cutter, a placement tray is used for transportation. After the production of the PCB milling cutter is completed, an operator directly places the placement tray with the PCB milling cutter inserted on the first conveyor, and another operator places the placement plate on the second conveyor in sequence. Under the action of the second conveyor, the empty placement plate moves to the top of the first conveyor. With the transportation of the first conveyor, the placement tray moves to the top of it and the whole row of PCB milling cutters abuts against the limit rod. Under the action of the limit rod, the placement tray stops moving, and then the driving mechanism drives the moving plate to slide along the N-shaped groove, and the moving plate moves in the direction close to the placement tray, and then moves downward, so that the two clamping rods move to both sides of the first row of PCB milling cutters on the placement tray, and then the whole row of PCB milling cutters is clamped under the action of the clamping mechanism. After that, the driving mechanism drives the moving plate to move along the N-shaped groove to the other end. At this time, the clamped PCB milling cutter first rises and then moves horizontally, and finally moves downward and is inserted into the placement plate placed on the second conveyor. Finally, the clamping mechanism drives the two clamping rods to separate, and the second conveyor runs a certain distance, and moves the empty placement plate to just above the first conveyor. This can be repeated to achieve the effect of automatically inserting the PCB milling cutter. The operator only needs to pack the placement plate with the PCB milling cutter inserted into the packaging box, and there is no need to manually insert the PCB milling cutter, which greatly improves the packaging speed of the PCB milling cutter. In addition, in the actual production process, in order to facilitate processing, the spacing between the PCB milling cutters on the placement tray is larger, but during packaging, such a large spacing is not required. Therefore, when the spacing between the PCB milling cutters on the placement tray is inconsistent with the spacing frame of the sockets on the placement board, the spacing adjustment mechanism on the clamping rod will automatically adjust the clamp of the PCB milling cutter to ensure that the PCB milling cutter can be accurately inserted into the placement board.

[0009] A limit strip is fixed on the first conveyor, a groove is provided on the lower surface of the placement plate, and the groove is aligned with the limit strip, a plurality of equally spaced gap blocks are detachably fixed on the second conveyor belt, the placement plate and the gap blocks are alternately distributed, a support plate is fixed on the mounting plate, and the support plate fits the inner wall of the second conveyor belt.

[0010] By adopting the above structure, the limit bar can position the placement disk, further ensuring that the position of the PCB milling cutter can be aligned with the placement plate; the gap block is detachable, and gap blocks of different widths can be replaced to adjust the spacing between different placement plates, so that the spacing between two adjacent holes on two adjacent placement plates is consistent with the spacing between the holes on the same placement plate; when the number of PCB milling cutters in the same row on the placement disk is inconsistent with the number of holes on the placement plate, the device can still continue to operate, and the support plate fits against the inner wall of the second conveyor belt, which can prevent the placement plate from tilting and improve the smoothness of equipment operation.

[0011] The driving mechanism includes two fixed plates fixed at both ends of the mounting plate, a threaded rod is rotatably arranged between the two fixed plates, and a driving motor for driving the threaded rod to rotate is installed on one of the fixed plates, a threaded sleeve is threadedly connected to the threaded rod, a driving plate is arranged on the side of the mounting plate away from the clamping rod, and a frame plate is fixed on the mounting plate, the upper edge of the driving plate is slidably arranged between the frame plate and the mounting plate, the side end of the driving plate is fixedly connected to the threaded sleeve, a V-shaped groove is opened on the driving plate, a sliding block is fixed on the side of the moving plate away from the slide rail, and a fixed shaft is fixed on the sliding block, the sliding block is slidably arranged in the N-shaped groove, and the fixed shaft is slidably arranged in the V-shaped groove.

[0012] With the above structure, the driving motor can drive the threaded rod to rotate repeatedly, and drive the driving plate to reciprocate through the threaded sleeve. When the clamping rod is in the state of clamping the PCB milling cutter and the slider is located at one end of the N-shaped groove close to the placement disk, the driving plate is also located close to the placement disk. At this time, the driving motor drives the driving plate to move in the direction close to the placement plate. At this time, the inside of the V-shaped groove will push the fixed axis upward, and the slider will rise along the N-shaped groove. When the slider moves to the top, the fixed axis moves to the top of the V-shaped groove, and drives the moving plate along the horizontal part of the N-shaped groove along the driving plate. When it moves to the other vertical part of the N-shaped groove, the other side of the V-shaped groove will drive the fixed axis to move downward. At this time, the slider moves downward. Similarly, the reverse movement of the driving plate will also drive the slider to move along the N-shaped groove.

[0013] A magnetic block is fixed on the upper end of the movable plate, and an iron bar is fixed on the side wall of the mounting plate, and the iron bar is located directly above the magnetic block.

[0014] With the above structure, when the slider drives the moving plate to move to the top, the magnetic block will absorb the iron bar, generating a large suction force to prevent the slider from falling down and prevent the device from getting stuck.

[0015] The clamping mechanism includes a lifting block, a sliding hole is opened in the middle position of the slide rail, the lifting block is slidably arranged in the sliding hole, and a trapezoidal block is fixed at one end of the lifting block, and a limiting bolt is fixed on the side of the other end, an extrusion plate is fixed under the sliding seat, and a tension spring is fixed between the two extrusion plates, the two extrusion plates are abutted against the side ends of the trapezoidal block, and the side ends of the extrusion plates are chamfered, an extrusion block is fixed on the mounting plate, and the extrusion block is located directly below one end of the N-shaped groove close to the placement plate, and a pressing assembly is provided on the side of the mounting plate away from the extrusion block.

[0016] With the above structure, when the two clamping rods move to the top of the placement plate, the pressing assembly will press the lifting block downward, so that the trapezoidal block moves to the bottom of the two extrusion plates. At this time, under the action of the tension spring, the two extrusion plates move closer to the middle, driving the sliding seat and the clamping rod to move closer to the middle, clamping the PCB milling cutter; when the two clamping rods move to the other end of the N-shaped groove and the bottom of the PCB milling cutter has been inserted into the jack of the placement plate, the moving plate continues to move downward, and at this time, under the action of the extrusion block, the trapezoidal block is squeezed upward between the two extrusion plates, separating the two clamping rods and releasing the clamped PCB milling cutter. This can be repeated to achieve the insertion and removal of the PCB milling cutter.

[0017] The pressing assembly comprises a lifting plate, a sliding groove is provided on the mounting plate, the lifting plate is slidingly arranged on the edge of the mounting plate through the sliding groove damping, a lifting groove is provided on the lifting plate, and a lifting rod is slidingly arranged in the lifting groove, a first rack is fixed to the side end of the lifting rod, a pressure rod is fixed to the upper end of the lifting rod, a transmission gear is rotatably arranged in the lifting groove, a second rack is fixed to the side of the mounting plate, and the first rack and the second rack are evenly meshed with the transmission gears, the lifting plate is made of iron material, and a magnet is embedded in the lower surface of the sliding seat close to the lifting plate.

[0018] With the above structure, when the moving plate moves downward, it will bring the lifting plate downward with it. At this time, the transmission gear rolls downward along the second rack, so that the first rack, the lifting rod and the pressure rod descend at twice the speed of the lifting plate. When the moving plate moves to the bottom, the pressure rod just squeezes the lifting block downward, squeezing the trapezoidal block to the bottom of the two squeezing plates. When the moving plate rises, the lifting plate will be reset under the action of the magnetic suction force. At this time, the pressure rod also rises at twice the speed and will not hinder the movement of the moving plate.

[0019] The spacing adjustment mechanism includes an adaptive component and a rotating roller. The rotating roller is rotatably arranged on the outside of one of the clamping rods, and a long groove is provided on the clamping rod close to the rotating roller, and a plurality of sliding clamps are slidably arranged in the long groove, and a protrusion is provided on the side of the sliding clamp close to the rotating roller, and a plurality of curved grooves are provided on the rotating roller, and the inclination angles of the curved grooves gradually increase from the middle to both sides, and the protrusions are slidably arranged in the curved grooves at corresponding positions, a driving gear is fixed to the end of the rotating roller, and a mounting frame is fixed to the mounting plate, and a third rack is detachably connected to the mounting frame, and the adaptive component is arranged on another clamping rod.

[0020] By adopting the above structure, the spacing between the PCB milling cutters on the placement plate is relatively large, but when packaging, such a large spacing is not required, and the third rack can be retained, otherwise the third rack can be removed. When in use, each sliding clamp cooperates with the adaptive component to clamp the PCB milling cutter. When passing under the third rack, the third rack meshes with the driving gear, driving the driving gear to rotate, and under the action of each curved groove, each sliding clamp is gathered to the middle, so that when the PCB milling cutter moves to the top of the placement plate, it can be aligned with the jack on the placement plate, and according to the different lengths of the third racks, the spacing between the PCB milling cutters can be adjusted to different sizes, which can adapt to various specifications of placement plates and clamp various specifications of PCB milling cutters, thereby improving the scope of application of the device.

[0021] The self-adaptive component comprises a clamping belt and two elastic belts. The two elastic belts are respectively fixed at two ends of the clamping belt, and the other ends of the two elastic belts are respectively fixed at two ends of the clamping rod.

[0022] With the above structure, when the two clamping rods approach each other, the sliding clamp block cooperates with the clamping belt to clamp the PCB milling cutter. When the sliding clamp block moves toward the middle, the clamping belt will wrinkle to adapt to the change of the position of the PCB milling cutter, and at the same time, the elastic belts at both ends will be tightened. When the two clamping rods move away from each other, the elastic belt drives the clamping belt to return to its original state.

[0023] Compared with the prior art, this automatic packaging device for PCB milling cutter production has the following advantages:

[0024] 1. Through the driving mechanism, the clamping mechanism, the clamping rod, the first conveyor and the second conveyor, the PCB milling cutter on the placement tray can be automatically inserted on the placement plate, and the operator does not need to manually insert the PCB milling cutter, which improves the safety during packaging, and can be inserted in batches, thereby improving the packaging speed of the PCB milling cutter.

[0025] 2. Through the spacing adjustment mechanism, the spacing between the PCB milling cutters can be adjusted during the transfer of the PCB milling cutters, so that the device can package PCB milling cutters of different specifications, thereby improving the application range of the device.

After the production of the PCB milling cutter is completed, the operator directly places the placement tray 2 with the PCB milling cutter inserted on the first conveyor 1, and another operator places the placement plate 4 on the second conveyor 3 in turn. Under the action of the second conveyor 3, the empty placement plate 4 moves to the top of the first conveyor 1, and as the first conveyor 1 is moved, the PCB milling cutter is moved to the top of the first conveyor 1. During the transportation of the machine 1, the placement tray 2 moves to the position where the entire row of PCB milling cutters above it abuts against the limit rod 14. Under the action of the limit rod 14, the placement tray 2 stops moving, and then the driving mechanism 8 drives the moving plate 7 to slide along the N-shaped groove 6.

At this time, the slider 807 moves downward. Similarly, the reverse movement of the driving plate 805 will also drive the slider 807 to move along the N-shaped groove 6.

At this time, under the action of the tension spring 1206, the two extrusion plates 1204 move closer to the middle, driving the sliding seat 10 and the clamping rod 11 to move closer to the middle, clamping the PCB milling cutter. When the two clamping rods 11 move to the other end of the N-shaped groove 6 and the bottom of the PCB milling cutter has been inserted into the jack of the placement plate 4, the moving plate 7 continues to move downward.

When the movable plate 7 moves to the bottom, the pressure rod 1213 just squeezes the lifting block 1201 downward, squeezing the trapezoidal block 1202 to the bottom of the two squeezing plates 1204, and when the movable plate 7 rises, the lifting plate 1208 will be reset under the action of the magnetic suction force. At this time, the pressure rod 1213 also rises at twice the speed and will not hinder the movement of the movable plate 7.

[0045] The spacing adjustment mechanism 13 includes an adaptive component and a rotating roller 1303, the rotating roller 1303 is rotatably arranged on the outside of one of the clamping rods 11, and a long groove 1301 is provided on the clamping rod 11 close to the rotating roller 1303, and a plurality of sliding clamps 1302 are slidably arranged in the long groove 1301, and a protrusion is provided on the side of the sliding clamp 1302 close to the rotating roller 1303, and a plurality of curved grooves 1304 are provided on the rotating roller 1303, and the inclination angles of the plurality of curved grooves 1304 gradually increase from the middle to the two sides, and the protrusions are slidably arranged in the curved grooves 1304 at corresponding positions, a driving gear 1305 is fixed to the end of the rotating roller 1303, and a mounting frame 1306 is fixed to the mounting plate 5, and a third rack 1307 is detachably connected to the mounting frame 1306, and the adaptive component is arranged on the other clamping rod 11; PCB on the placement plate 2 The spacing between the milling cutters is relatively large, but when packaging, such a large spacing is not needed, and the third rack 1307 can be retained, otherwise the third rack 1307 can be removed. When in use, each sliding clamp 1302 cooperates with the adaptive component to clamp the PCB milling cutter. When passing under the third rack 1307, the third rack 1307 engages with the driving gear 1305, driving the driving gear 1305 to rotate, and under the action of each curved groove 1304, each sliding clamp 1302 is gathered to the middle, so that when the PCB milling cutter moves to the top of the placement plate 4, it can be aligned with the jack on the placement plate 4, and according to the different lengths of different third racks 1307, the spacing between the PCB milling cutters can be adjusted to different sizes, which can adapt to various specifications of placement plates 4 and clamp various specifications of PCB milling cutters, thereby improving the scope of application of the device.

[0046] The adaptive component includes a clamping belt 1308 and two elastic belts 1309. The two elastic belts 1309 are respectively fixed at the two ends of the clamping belt 1308, and the other ends of the two elastic belts 1309 are respectively fixed at the two ends of the clamping rod 11; when the two clamping rods 11 approach each other, the sliding clamp block 1302 cooperates with the clamping belt 1308 to clamp the PCB milling cutter. When the sliding clamp block 1302 moves toward the middle, the clamping belt 1308 will wrinkle to adapt to the change of the position of the PCB milling cutter, and at the same time, the elastic belts 1309 at both ends will be tightened. When the two clamping rods 11 move away from each other, the elastic belt 1309 drives the clamping belt 1308 to return to its original state.

[0047] The above-mentioned fixing methods are the most commonly used fixing connection methods in this field, such as welding, bolt connection, etc.; the above-mentioned electrical components, such as the drive motor 803, etc., are all existing technology products and can be directly purchased and used in the market, and the specific principles will not be repeated.

[0048] Working principle of the present invention:

[0049] Driving mode: the driving motor 803 can drive the threaded rod 802 to rotate repeatedly, and drive the driving plate 805 to reciprocate through the threaded sleeve 804. When the clamping rod 11 is in the state of clamping the PCB milling cutter and the slider 807 is located at one end of the N-shaped groove 6 close to the placement disk 2, the driving plate 805 is also located near the placement disk 2. At this time, the driving motor 803 drives the driving plate 805 to move in the direction close to the placement plate 4. At this time, the inside of the V-shaped groove 806 will push the fixed shaft 808 upward, and the slider 807 will rise along the N-shaped groove 6. When the slider 807 moves to the top, the fixed shaft 808 moves to the top of the V-shaped groove 806, and drives the movable plate 7 to move along the horizontal part of the N-shaped groove 6 along the driving plate 805. When it moves to another vertical part of the N-shaped groove 6, the other side of the V-shaped groove 806 will drive the fixed shaft 808 to move downward. At this time, the slider 807 moves downward. Similarly, the reverse movement of the driving plate 805 will also drive the slider 807 to move along the N-shaped groove 6.

[0050] When in use, the placement tray 2 is used for transportation during the processing of the PCB milling cutter. After the production of the PCB milling cutter is completed, the operator directly places the placement tray 2 with the PCB milling cutter inserted on the first conveyor 1, and another operator places the placement plate 4 on the second conveyor 3 in sequence. Under the action of the second conveyor 3, the empty placement plate 4 moves to the top of the first conveyor 1. With the transportation of the first conveyor 1, the placement tray 2 moves to the top thereof, and the whole row of PCB milling cutters is against the limit rod 14. Under the action of the limit rod 14, the placement tray 2 The moving plate 7 stops moving, and then the driving mechanism 8 drives the moving plate 7 to slide along the N-shaped groove 6, and the moving plate 7 moves toward the direction close to the placement plate 2, and then moves downward, so that the two clamping rods 11 move to both sides of the first row of PCB milling cutters on the placement plate 2, and when the moving plate 7 moves downward, it will bring the lifting plate 1208 to move downward. At this time, the transmission gear 1214 rolls downward along the second rack 1215, so that the first rack 1212, the lifting rod 1211 and the pressure rod 1213 descend at twice the speed of the lifting plate 1208. When the moving plate 7 moves to the lowest point, the lifting plate 1208 is moved downward. When the pressing rod 1213 is in the right position, it just presses the lifting block 1201 downwards, and squeezes the trapezoidal block 1202 to the bottom of the two squeezing plates 1204. At this time, under the action of the tension spring 1206, the two squeezing plates 1204 move closer to the middle, driving the sliding seat 10 and the clamping rod 11 to move closer to the middle, clamping the PCB milling cutter. After that, the driving mechanism 8 drives the moving plate 7 to move along the N-shaped groove 6 to the other end. At this time, the clamped PCB milling cutter first rises and then moves horizontally, and finally moves downward and is inserted into the placement plate 4 placed on the second conveyor 3. When the two clamping rods 11 move When the moving plate 7 moves to the other end of the N-shaped slot 6 and the bottom of the PCB milling cutter has been inserted into the jack of the placement plate 4, the moving plate 7 continues to move downward. At this time, under the action of the extrusion block 1207, the trapezoidal block 1202 is squeezed upward to between the two extrusion plates 1204, the two clamping rods 11 are separated, and the clamped PCB milling cutter is released. This can be repeated to achieve the effect of automatically inserting the PCB milling cutter. The operator only needs to pack the placement plate 4 with the PCB milling cutter inserted into the packaging box, and there is no need to manually insert the PCB milling cutter, which greatly improves the packaging speed of the PCB milling cutter.

[0051] In addition, in actual use, the spacing between PCB milling cutters on the placement tray 2 is often large, but during packaging, such a large spacing is not required and the third rack 1307 can be retained, otherwise the third rack 1307 can be removed. During use, when each sliding clamp block 1302 cooperates with the clamping belt 1308 to clamp the PCB milling cutter, when passing under the third rack 1307, the third rack 1307 engages with the driving gear 1305, driving the driving gear 1305 to rotate, and under the action of each curved groove 1304, each sliding clamp block 1302 is gathered to the middle, and the clamping belt 1308 will be wrinkled to adapt to the change in the position of the PCB milling cutter, so that the PCB milling cutter can be aligned with the jack on the placement plate 4 when it moves to the top of the placement plate 4, and according to the different lengths of different third racks 1307, the spacing between the PCB milling cutters can be adjusted to different sizes, which can adapt to various specifications of placement plates 4 and clamp various specifications of PCB milling cutters, thereby improving the scope of application of the device.

[0052] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
