Description

Technical Field

[0001] The invention relates to the technical field of harmonica manufacturing, in particular to a harmonica reed positioning plate material taking mechanism. Background Art

[0002] The harmonica, also known as a mouth organ, mouth harp or chord, is a small free-reed instrument. It consists of a series of reeds attached to a frame called a reed plate. When the player places the harmonica in their mouth and blows or inhales to move air through the reeds, the reeds vibrate and produce sound. The harmonica is popular for its portability, ease of learning, and wide range of sounds. The internal structure of the harmonica includes the following: reed, reed positioning plate, fret and cover plate. The reed is the core part of the harmonica, responsible for vibration and sound generation. The reed is fixedly mounted on the reed plate. The reed positioning plate is an important part of the harmonica's structure. Inside the harmonica, the reed positioning plate is a flat plate used to fix the reeds, usually made of metal, such as brass, stainless steel or phosphor bronze. The reeds are fixed on these positioning plates, and each hole corresponds to at least one reed. In some harmonica designs, each hole will have two reeds, which are responsible for producing different sounds when blowing and inhaling respectively. The reed positioning plates are usually punched by a punching machine, and the punched reed positioning plates will be collected and stored in a unified manner for transfer and subsequent reed installation; In the process of making the harmonica, the reed needs to be installed in the hole of the reed positioning plate. Therefore, before the reed installation process is carried out, the reed positioning plate needs to be transferred from the storage device to the reed installation station. The existing reed installation process is usually done manually, where the reed is riveted or welded to the upper reed positioning plate, and the process of naturally transferring the reed positioning plate is also done manually. Manual work will inevitably lead to mistakes and reduced work efficiency due to individual worker fatigue. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a material taking mechanism for automatically transferring the harmonica reed positioning plate.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a harmonica reed positioning plate material taking mechanism, comprising a workbench and a reed positioning plate, a discharging assembly is arranged on one side of the workbench, the discharging assembly comprises a feeding mechanism and a pushing mechanism, the feeding mechanism transports the reed positioning plate upward in sequence, the pushing mechanism pushes the reed positioning plate to move, and screw holes are opened on both sides of the reed positioning plate; A material taking assembly is arranged above the outside of the workbench, and the inside of the material taking assembly includes a material grabbing mechanism and a material releasing mechanism, the material grabbing mechanism grabs the reed positioning plate, and the material releasing mechanism releases the reed positioning plate; A material receiving assembly is arranged above the outside of the workbench, and the inside of the material receiving assembly includes a moving mechanism and a clamping mechanism. The moving mechanism drives the reed positioning plate to move, and the clamping mechanism clamps the reed positioning plate above the moving mechanism.

[0005] Through the above technical scheme, the reed positioning plate can be conveyed out in sequence by the feeding mechanism after storage, and each time a reed positioning plate is conveyed, it will be pushed out by the pushing mechanism until the reed positioning plate is pushed into the slot, and then the reed positioning plate placed in the slot is grabbed by the grabbing mechanism, and then driven by the electric slide, the reed positioning plate is moved to the top of the receiving assembly, at this time the discharge mechanism is started to release the reed positioning plate, and the reed positioning plate will fall to the top of the receiving plate under the action of gravity, and be engaged by the engaging mechanism, and then the reed positioning plate is driven to move by the moving mechanism until the reed positioning plate moves to a suitable welding position, so that welding work can be carried out.

[0006] Preferably, a bracket is fixedly provided on the outer upper end of the workbench, a support plate is fixedly provided on the outer upper end of the workbench on the side close to the discharging component, an electric slide is fixedly provided on the outer bottom surface of the bracket, a moving block is provided inside the electric slide, the electric slide is connected to the support plate, the support plate is in the shape of an "I", and a guide block is fixedly provided on the lower end of the support plate on the side close to the discharging component.

[0007] Through the above technical solution, the setting of the bracket can better support the support plate, and the electric slide can be connected to the upper surface of the support plate for fixation, and the setting of the guide block allows the reed positioning plate to be contracted during the pushing process and move along the inner wall of the bracket without tilting easily until the reed positioning plate enters the slot and is engaged.

[0008] Preferably, the feeding mechanism includes a storage groove provided inside the workbench, a spring is fixedly arranged on the bottom surface of the storage groove, the spring is fixedly connected to a lifting plate at one end away from the bottom surface of the storage groove, a spring positioning plate is placed above the outside of the lifting plate, fixing holes are provided on both sides of the storage groove inside the workbench, and a fixed shaft is fixedly arranged on both sides of the storage groove at the upper end of the outside of the workbench, pressure blocks are sleeved on the outside of the fixed shafts, rotating holes are provided inside the pressure blocks, the fixed shafts are located inside the rotating holes, bolts are provided inside the pressure blocks, the bolts pass through the pressure blocks and are located inside the fixing holes, and sliding grooves are provided on the bottom surface of the pressure blocks.

[0009] Through the above technical solution, after the reed positioning plate is placed and stored inside the storage slot, the spring will push the reed positioning plate out of the storage slot through the lifting plate due to the elastic force of the spring, and at the same time, a pressure block is provided above the workbench, and the pressure block is located at both ends of the storage slot, which will block the reed positioning plate to prevent the reed positioning plate from popping out directly from the storage slot, and the pressure block can be rotated on the surface of the workbench, thereby fully opening the storage slot to facilitate the placement and storage of the reed positioning plate.

[0010] Preferably, the pushing mechanism includes a fixed plate fixedly arranged at the upper end of the outside of the workbench, a first electric telescopic rod is fixedly arranged on the surface of the fixed plate on one side close to the storage groove, a connecting plate is fixedly connected to the output end of the first electric telescopic rod, a push plate is arranged on the outside of the connecting plate on the side away from the first electric telescopic rod, rod holes are opened inside the push plate and the connecting plate, a shaft rod is arranged inside the push plate and the connecting plate, and the shaft rod is located inside the rod hole.

[0011] Through the above technical solution, after the feeding mechanism pushes out the spring positioning plate, the extension of the first electric telescopic rod can be used to drive the connecting plate and the push plate to move, and the push plate will push the spring positioning plate out of the sliding groove opened inside the pressing block. When the spring positioning plate is pushed away from the pressing block and the push plate needs to be reset, the first electric telescopic rod is retracted to drive the connecting plate and the push plate to reset. During the resetting process, the push plate loses the support of the connecting plate and rotates around the shaft rod, so that it will not hinder the spring positioning plate that is subsequently ejected from the storage groove.

[0012] Preferably, a slot is provided in the middle of the workbench, and slot holes are provided on both sides of the slot. The inner diameter of the slot hole is larger than the diameter of the screw hole, and the shape of the slot matches the shape of the spring positioning plate.

[0013] Through the above technical solution, the reed positioning plate can be clamped between the inside of the clamping slot, and the screw hole corresponds to the clamping hole.

[0015] Through the above technical solution, the second electric telescopic rod drives the pressure plate to descend, so that the pressure plate moves toward the direction of the spring positioning plate. At the same time, the clamping column and the clamping petal pass through the screw hole and enter the inside of the clamping hole. The clamping column finally contacts the bottom surface of the inner hole. The pressure plate will drive the pressure ring to apply pressure to the clamping petal. The clamping petal spreads out under the support of the truncated cone-shaped clamping column and is clamped by the sleeve ring. Then the second electric telescopic rod is contracted to drive the pressure plate to rise, and the spread out clamping petals will support and lift the spring positioning plate.

[0016] Preferably, the pressure ring, the clamping flap and the sleeve ring are all located below the pressure plate, the clamping flap can be opened by the clamping column, the clamping flap can be contracted by the sleeve ring, the sleeve ring restricts the clamping flap, the outer diameter of the sleeve ring is larger than the inner diameter of the screw hole, and the maximum diameter surrounded by the clamping flap is equal to the diameter of the screw hole.

[0017] Through the above technical solution, the card petal will pass through the screw hole and enter the inside of the card hole in the contracted state, and will be larger than the diameter of the screw hole after opening inside the card hole. In this way, when the card petal rises, it will drive the reed positioning plate to rise, and the diameter of the ring is larger than the screw hole. In this way, when the card petal enters the screw hole, the ring will be blocked by the reed positioning plate and will not enter the inside of the screw hole together.

[0018] Preferably, the discharge mechanism includes a sleeve plate arranged above the outside of the pressing plate, the sleeve plate is placed on the outside of the telescopic end of the second electric telescopic rod, the two sides of the outside of the sleeve plate are fixedly connected to the end of the connecting rod away from the clamping column, and the third electric telescopic rod is fixedly arranged on both sides between the sleeve plate and the pressing plate, and the movable end of the third electric telescopic rod is connected to the sleeve plate.

[0019] Through the above technical solution, when you want to release the reed positioning plate, start the third electric telescopic rod to drive the sleeve plate to move toward the pressure plate, so that the sleeve plate will drive the connecting rod to move, so that the card column will be detached from the inside of the card petal. After the card petal is no longer supported by the truncated cone-shaped card column, the diameter of the card petal is restored to be equal to the diameter of the screw hole, so that the reed positioning plate is no longer blocked and the reed positioning plate will be released under the action of gravity.

[0020] Preferably, the moving mechanism comprises a slide groove provided on the inner surface of the workbench, a slider is provided inside the slide groove, a receiving plate is fixedly connected to the outer upper end of the slider, and the receiving plate moves through the cooperation between the slider and the slide groove.

[0021] Through the above technical solution, the receiving plate can be freely moved inside the slide groove through the slider, and the reed positioning plate can be moved together with it, so that the reed positioning plate can be moved to a suitable work station for welding or riveting process.

[0023] Through the above technical solution, after the reed positioning plate is grabbed by the grabbing mechanism, it will be driven by the electric slide to move until it contacts the baffle, then the discharge mechanism is started to release the reed positioning plate, and under the action of gravity, the reed positioning plate falls above the receiving plate, and the clamping rod is located inside the screw hole, so that the reed positioning plate can be limited and fixed.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 - Fig.12 As shown, the embodiment of the present invention provides a harmonica reed positioning plate material taking mechanism, including a workbench 200 and a reed positioning plate 500. A discharging assembly is arranged on one side of the workbench 200. The discharging assembly includes a feeding mechanism and a pushing mechanism. The feeding mechanism transports the reed positioning plates 500 upward in sequence, and the pushing mechanism pushes the reed positioning plates 500 to move. Screw holes 501 are provided on both sides of the reed positioning plates 500. The discharging assembly ensures that the discharging and feeding work of the reed positioning plates 500 are stable, and multiple reed positioning plates 500 will not be pushed out at one time. A material taking assembly is arranged above the outside of the workbench 200, and the material taking assembly includes a material grabbing mechanism and a material discharging mechanism. The material grabbing mechanism grabs the reed positioning plate 500, and the material discharging mechanism releases the reed positioning plate 500. The arrangement of the material taking assembly can ensure that the reed positioning plates 500 pushed out in sequence by the material discharging assembly can be individually grabbed, moved and released, so as to ensure that each reed positioning plate 500 will not fall during the material taking process, and no grabbing error will occur;

[0029] A material receiving assembly is arranged above the outside of the workbench 200, and the interior of the material receiving assembly includes a moving mechanism and a locking mechanism. The moving mechanism drives the reed positioning plate 500 to move, and the locking mechanism locks the reed positioning plate 500 above the moving mechanism. The setting of the material receiving assembly can enable the reed positioning plate 500 transferred from the material taking assembly to be quickly collected and transferred, and then carry out subsequent processing steps.

[0030] like Figure 1 , Figure 2 , Figure 6 - Figure 8 As shown, a bracket 400 is fixedly provided on the upper outer end of the workbench 200, and a support plate 202 is fixedly provided on the upper outer end of the workbench 200 on the side close to the discharging component. The arrangement of the bracket 400 and the support plate 202 can make the installation of the electric slide 402 more convenient. An electric slide 402 is fixedly provided on the bottom outer surface of the bracket 400, and a moving block 401 is arranged inside the electric slide 402. The moving block 401 can facilitate the movement of the material picking component after grabbing the spring positioning plate 500. The electric slide 402 is connected to the support plate 202, and the support plate 202 is in the shape of an "I". On the one hand, the support plate 202 can provide a block and limit for the push plate 106 during the pushing process, and on the other hand, it is also a limit for the movement of the material picking component. A guide block 210 is fixedly provided on the lower end of the support plate 202 on the side close to the discharging component. The arrangement of the guide block 210 can ensure that the spring positioning plate 500 will not be stuck in the gap of the support plate 202 during the pushing process.

[0031] like Figure 1 - Figure 5As shown, the feeding mechanism includes a workbench 200 with a storage groove 205 opened inside, a spring 209 is fixedly arranged on the bottom surface of the storage groove 205, and the spring 209 is fixedly connected to a lifting plate 208 at one end away from the bottom surface of the storage groove 205. A spring positioning plate 500 is placed above the lifting plate 208, so that with the cooperation of the spring 209 and the lifting plate 208, the spring positioning plate 500 will be pushed out of the storage groove 205 in order, and the workbench 200 has fixing holes 206 opened on both sides of the storage groove 205, and the upper end of the outside of the workbench 200 is fixedly arranged on both sides of the storage groove 205, and the fixed shaft 204 is sleeved with a pressure block 103 on the outside, and the pressure block 103 is provided with a rotating hole 108 inside, and the fixed The shaft 204 is located inside the rotating hole 108, so that the pressure block 103 can rotate around the fixed shaft 204, so that the pressure block 103 can switch between blocking the spring positioning plate 500 and not blocking the spring positioning plate 500 at will. Bolts 107 are arranged inside the pressure block 103, and the bolts 107 pass through the pressure block 103 and are located inside the fixing hole 206. The setting of the bolts 107 prevents the pressure block 103 from easily tilting or rotating when blocking the spring positioning plate 500. The bottom surface of the pressure block 103 is provided with a slide-out groove 104, and the thickness between the top surface of the slide-out groove 104 and the workbench 200 is the thickness of the spring positioning plate 500, so that it can be ensured that only one spring positioning plate 500 is pushed out by the push plate 106 each time.

[0032] The push mechanism includes a fixed plate 100 fixedly arranged at the upper end of the outer side of the workbench 200, a first electric telescopic rod 101 is fixedly arranged on the surface of the fixed plate 100 on one side close to the storage slot 205, a connecting plate 102 is fixedly connected to the output end of the first electric telescopic rod 101, a push plate 106 is arranged on the outer side of the connecting plate 102 away from the first electric telescopic rod 101, rod holes are opened inside the push plate 106 and the connecting plate 102, and shaft rods are arranged inside the push plate 106 and the connecting plate 102 105, the shaft 105 is located inside the rod hole, so that the push plate 106 is connected to the connecting plate 102 through the shaft 105, and the push plate 106 can only rotate in one direction around the shaft 105, that is, it rotates in the direction away from the connecting plate 102. When the push plate 106 rotates toward the connecting plate 102, the push plate 106 will fit tightly with the connecting plate 102, thereby jointly pushing the spring positioning plate 500, and the bottom surface of the push plate 106 fits with the surface of the workbench 200.

[0033] like Figure 4As shown, a slot 203 is provided in the middle of the workbench 200, and holes 207 are provided on both sides of the slot 203. The inner diameter of the hole 207 is larger than the diameter of the screw hole 501, so that the flaps 605 can be better spread out inside the hole 207 without being restricted by the inner diameter of the hole 207. The shape of the slot 203 is consistent with the shape of the reed positioning plate 500, so that the reed positioning plate 500 can be better engaged in the slot 203.

[0034] like Figure 1 - Figure 2 , Figure 7 - Fig.12 As shown, the material grabbing mechanism includes a second electric telescopic rod 600 fixedly arranged on the outer bottom surface of the moving block 401, and a pressing plate 602 is fixedly arranged at the output end of the second electric telescopic rod 600, so that the second electric telescopic rod 600 will drive the pressing plate 602 and other structures to move up and down, and through holes 604 are opened on both sides of the pressing plate 602, and a connecting rod 603 is arranged inside the through hole 604. The connecting rod 603 can be lifted and lowered inside the through hole 604, and the connecting rod 603 is far away from the second electric telescopic rod 600. One end is fixedly connected with a clamping column 609, and the clamping column 609 is truncated cone-shaped, so that the clamping flap 605 can be opened more smoothly through the clamping column 609. Both sides of the outer bottom surface of the pressure plate 602 are connected with pressure rings 608, and the pressure ring 608 is sleeved on the outside of the connecting rod 603. The clamping flap 605 is sleeved on the outside of the connecting rod 603. The clamping flap 605 is arranged in a circular array around the connecting rod 603, and the outer ring 606 is sleeved on the outside of the clamping flap 605. The setting of the ring 606 can prevent the clamping flap 605 from being scattered at will.

[0035] The pressure ring 608, the clamping flap 605 and the sleeve ring 606 are all located below the pressure plate 602. The clamping flap 605 can be opened by the clamping column 609, and the clamping flap 605 is contracted by the sleeve ring 606. The sleeve ring 606 restricts the clamping flap 605. The outer diameter of the sleeve ring 606 is larger than the inner diameter of the screw hole 501, so that the sleeve ring 606 will not enter the screw hole 501 opened in the spring positioning plate 500. The maximum diameter surrounded by the clamping flap 605 is equal to the diameter of the screw hole 501, so that the clamping flap 605 can enter the screw hole 501 when it is not opened.

[0036] The discharge mechanism includes a sleeve plate 601 arranged above the outside of the pressing plate 602, and the sleeve plate 601 is placed on the outside of the telescopic end of the second electric telescopic rod 600, so that the second electric telescopic rod 600 will not interfere with the sleeve plate 601 during the extension and retraction process. The two sides of the outside of the sleeve plate 601 are fixedly connected to the end of the connecting rod 603 away from the clamping column 609, so that when the sleeve plate 601 is lifted or lowered, the clamping column 609 will be driven to lift and move through the connecting rod 603. The third electric telescopic rod 607 is fixedly arranged on both sides between the sleeve plate 601 and the pressing plate 602, and the moving end of the third electric telescopic rod 607 is connected to the sleeve plate 601, and the third electric telescopic rod 607 will drive the sleeve plate 601 to move closer to or away from the pressing plate 602.

[0037] like Figure 7 - Figure 8 As shown, the moving mechanism includes a slide groove 201 provided on the inner surface of the workbench 200, a slider 303 is arranged inside the slide groove 201, and a receiving plate 300 is fixedly connected to the upper end of the outer side of the slider 303. The receiving plate 300 moves through the cooperation between the slider 303 and the slide groove 201. A plurality of slide grooves 201 are provided above the workbench 200, and the end position of each slide groove 201 is staggered. In this way, the receiving plate 300 moves after receiving the spring positioning plate 500, and will not interfere with each other during subsequent processes, and has a sufficiently large operating space.

[0038] The locking mechanism includes a baffle 301 fixedly connected to the outer upper surface of the receiving plate 300. The setting of the baffle 301 can block the material picking assembly so that the discharging mechanism can release the reed positioning plate 500. Both sides of the outer upper end of the receiving plate 300 are fixedly provided with a locking rod 302. The diameter of the locking rod 302 is equal to the inner diameter of the screw hole 501. The locking rod 302 can accurately fix and position the reed positioning plate 500.

[0039] Working principle: When the device is used for material taking, the pressing block 103 is first moved to rotate around the fixed axis 204 so that the pressing block 103 no longer blocks the receiving groove 205, and then the stamped spring positioning plate 500 is placed inside the receiving groove 205, and the pressing block 103 is rotated to the top of the spring positioning plate 500 to block it. In this way, under the elastic force of the spring 209, the lifting plate 208 will drive the spring positioning plate 500 to rise inside the receiving groove 205 and be blocked by the pressing block 103; Then, the first electric telescopic rod 101 is started to extend, thereby driving the push plate 106 to move through the connecting plate 102. The push plate 106 will push the spring positioning plate 500 out of the pressing block 103 during the movement. After the spring positioning plate 500 leaves the slide-out slot 104 provided in the pressing block 103, it will be pushed further by the push plate 106 until the push plate 106 fits with the vertical plate inside the support plate 202. At this time, the push plate 106 can no longer be pushed, and the spring positioning plate 500 also smoothly enters the slot 203. When the topmost reed positioning plate 500 leaves the receiving slot 205, the spring 209 will continue to push the next reed positioning plate 500 out from the receiving slot 205; Then, the first electric telescopic rod 101 is started to retract. During the retraction of the first electric telescopic rod 101, the connecting plate 102 and the push plate 106 are driven to retract and reset. During the resetting process of the push plate 106, because the next spring positioning plate 500 is pushed out by the spring 209, the push plate 106 will be blocked by the next spring positioning plate 500, and the push plate 106 will rotate around the shaft 105 until the push plate 106 is located above the next spring positioning plate 500. When the push plate 106 leaves the top of the spring positioning plate 500, it will then resume the state of being in contact with the connecting plate 102, and the subsequent pushing work can be carried out; When the spring positioning plate 500 enters the slot 203, the electric slide 402 is started to drive the moving block 401 to move. The moving block 401 will drive the material taking component to move during the movement. When the material taking component is moved to the upper part of the slot 203; The second electric telescopic rod 600 is started to extend, thereby driving the pressure plate 602 to descend, and at the same time, the clamping column 609 and the clamping flap 605 enter the screw holes 501 opened on both sides of the spring positioning plate 500, until the clamping column 609 and the clamping flap 605 enter between the clamping hole 207. After the clamping column 609 enters the bottom surface of the clamping hole 207, the second electric telescopic rod 600 and the third electric telescopic rod 607 are started to extend at the same time. In this way, when the pressure plate 602 continues to press down, the clamping column 609 will continue to stand on the bottom surface of the clamping hole 207 through the connecting rod 603, and the pressure plate When the clamp 602 is pressed downward, it will drive the pressing ring 608 to be pressed downward, and the pressing ring 608 will press the card flap 605 to move downward. Because the card flap 605 is arranged in a circular array around the connecting rod 603, and the clamp column 609 is in a truncated cone shape, after the card flap 605 is pressed downward by the pressing ring 608, the card flap 605 will spread out along the side wall of the clamp column 609, so that the overall diameter of the card flap 605 is larger than the diameter of the screw hole 501. At the same time, when the card flap 605 is spread out, it will be clamped by the ring 606 to ensure that the card flap 605 always remains in a spread out state. Then, the length of the third electric telescopic rod 607 is maintained, and the second electric telescopic rod 600 is started to retract, so that the second electric telescopic rod 600 drives the pressing plate 602 to rise, and at the same time drives the cover plate 601 to rise through the third electric telescopic rod 607. During the rising process of the cover plate 601, the clamping column 609 is driven to rise through the connecting rod 603. During this process, the clamping column 609 continuously applies force to the clamping petal 605, so that the clamping petal 605 is always kept open, so that the spring positioning plate 500 is supported by the spread-out clamping petals 605 and is lifted up; Then, the electric slide 402 drives the material taking assembly and the spring positioning plate 500 to move until the material taking assembly contacts the baffle 301; At this time, the third electric telescopic rod 607 is started to shrink, so that the third electric telescopic rod 607 drives the sleeve plate 601 to move toward the pressure plate 602, so that the connecting rod 603 is driven by the sleeve plate 601 to press down, and the clamping column 609 also drops, and the clamping column 609 is connected to the clamping rod 302, and then the clamping petal 605 loses the obstruction of the clamping column 609, and the clamping petal 605 is gathered by the collar 606 and re-attached to the surface of the connecting rod 603, so that the diameter of the clamping petal 605 is restored to the diameter size of the screw hole 501, and the clamping petal 605 no longer supports the spring positioning plate 500, and the spring positioning plate 500 falls under the action of gravity; The reed positioning plate 500 will fall along the direction of the connecting rod 603 and the clamping rod 302 until the reed positioning plate 500 falls on the receiving plate 300 and the clamping rod 302 is located inside the screw holes 501 opened on both sides of the reed positioning plate 500; Finally, the receiving plate 300 can be moved by the cooperation between the slider 303 and the slide groove 201, and the spring positioning plate 500 is also driven to move. When the spring positioning plate 500 is moved to a suitable position, subsequent welding or riveting work can be carried out.
