Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bending device, and particularly relates to a dry reed shaping equipment. BACKGROUND

[0002] The dry reed is a circuit switch element controlled by a magnetic field signal, which is packaged with a reed made of soft magnetic material in a glass tube. As a basic electronic component, the dry reed is widely used in various electronic devices such as relays, sensors, safety systems, etc. The pins thereof usually need to be bent and shaped according to the actual circuit board layout or installation space.

[0003] The dry reed often needs to be shaped according to the installation requirements during use, such as being bent to a specific angle. The traditional dry reed shaping mainly relies on manual equipment, and the operator needs to complete three steps of feeding, pressing and shaping, and taking out the material one by one. Only one finished product can be produced for each set of operation, which is low in efficiency, high in labor cost, and difficult to guarantee the consistency of processing, and cannot meet the requirements of modern industrial production on efficiency and quality.

[0004] A dry reed shaping equipment (publication number CN111360176B) is proposed in the prior art to solve the above technical problems. The technical solution disclosed in the patent document is as follows: "The dry reed shaping equipment comprises a feeding device, a positioning device, a mechanical hand for transferring the dry reed, a shaping device, and an adjusting platform group. The feeding device comprises a slide, a material preparation disc at the upper end of the slide, and a feeding channel at the lower end of the slide. The feeding channel is a magnetic suspension channel, which comprises two fixed material plates, a magnetic plate adsorbed to the outer side of the fixed material plate, and a reinforcing magnetic block adsorbed to the outer side of the magnetic plate. The positioning device comprises a guide cylinder, which is a pneumatic finger. There is a positioning seat between the pneumatic fingers. The positioning seat comprises a fixed part, and the end of the fixed part extends a positioning table. The end of the fixed part and the side surface of the positioning table form a step. The shaping device comprises two clamping cylinders for clamping the dry reed pins on the positioning seat, and two bending cylinders for bending the clamped dry reed pins. The present application can adjust the span of the dry reed bending part by adjusting the adjusting platform group which can be adjusted front and back and left and right, and has high shaping efficiency and is convenient to use".

[0005] However, after the production is completed, the dry reed is usually directly placed in a common collection box, resulting in disordered accumulation of finished products. This disordered collection method causes the dry reeds to collide and entangle with each other, the fragile glass shell is easily broken, and the bent and shaped pins are also easily deformed due to extrusion. Especially for dry reeds used in precision applications or special occasions, the damage risk caused by this disordered collection method is higher. If subsequent neat arrangement is needed, additional manual sorting and placement are required, which is laborious and ineffective. SUMMARY

[0006] The present application aims to provide a dry reed shaping device to solve the problems in the background art.

[0007] To solve the above technical problems, the technical solution adopted by the present application is:

[0008] A dry reed shaping device, comprising a base plate, a feeding device, a mechanical hand for transferring dry reeds, a positioning device and a shaping device; further comprising: a double-shaft servo module fixedly installed on the top of the base plate, the movable end of the double-shaft servo module being fixedly connected with a material receiving platform, the double-shaft servo module being configured to drive the material receiving platform to move with high precision in two mutually perpendicular directions in the horizontal plane; a tray placed on the top of the material receiving platform, a gasket being arranged in the inner groove of the tray, the gasket being made of a flexible puncturable buffer material, the material being configured to be inserted and fixed by the pins of the dry reed, the thickness of the gasket being greater than the length of the bent part of the pin of the dry reed; a limiting assembly arranged on the top of the material receiving platform for limiting the movement of the tray relative to the material receiving platform in the horizontal direction.

[0009] With the above technical solution, without increasing the steps of the traditional shaping process, the automatic matrix arrangement of the shaped dry reeds is realized through the controllable displacement of the material receiving platform and the structural characteristics of the gasket; this solution effectively solves the problem of chaotic accumulation and mutual collision and entanglement of dry reeds caused by the traditional collection method, significantly reduces the risk of glass shell damage and pin deformation, realizes the integration of shaping and orderly collection of the overall structure, and does not require manual secondary arrangement, thereby ensuring product quality and improving production continuity; at the same time, the neat matrix arrangement provides great convenience for subsequent warehousing, transportation and automatic assembly, greatly improving production efficiency and product reliability.

[0010] Further improvement of the technical solution of the present application is that the shaping device comprises a cushion table fixedly connected to the top of the base plate, the top of the cushion table being fixedly connected with a sliding rail, the sliding rail being slidingly connected with a shaped boss, a clearance slot being arranged at the central position of the bottom of the shaped boss, a bending cylinder being fixedly connected to the top of the base plate, the piston rod of the bending cylinder being fixedly connected with a push block, the push block being in contact with the shaped boss; a fixed plate being fixedly connected to the top of the base plate at the position of the clearance slot, a first spring being fixedly connected between the fixed plate and the shaped boss, two bending heads being connected to the side of the shaped boss away from the bending cylinder through screws; a fixed block being fixedly connected to the top of the base plate, two die heads being connected to the central position of the top of the fixed block through screws, the side of each die head close to the shaped boss being fixedly connected with a placing block; an avoiding slot being arranged in the top of the fixed block and the inner wall of the clearance slot, a friction strip being fixedly connected in the avoiding slot, the outer surface of the friction strip being ground, and the sides of the two friction strips close to each other being in contact with each other.

[0011] The technical scheme is characterized in that: the forming boss is driven to complete precise bending by the bending cylinder; the forming boss is automatically reset by the first spring after the reset of the bending cylinder; during the reset process, the vibration caused by the mutual friction of the two groups of friction strips in the stroke part area (the process also exists when the bending action is performed, but does not exist in the bending process, but the process of the bending head approaching the lead pin, which does not affect the bending), can effectively eliminate the jamming state of the lead pin and the mold head, and assist the two end lead pins of the U-shaped reed (bent into a U shape) to naturally droop, so as to ensure that the direction of the lead pin meets the grabbing requirements.

[0012] The further improvement of the technical scheme is characterized in that: the far side of the two mold heads is hingedly connected with a swing arm, the bottom end of the swing arm is fixedly connected with a flexible pressing head, and the end of the swing arm close to the flexible pressing head is further fixedly connected with a counterweight; the end of the bending head is fixedly connected with a top block, the end of the top block away from the bending head is rotatably connected with a roller, and the roller is in contact with the swing arm; the side of the mold head close to the placing block is fixedly connected with a limiting block, and the top view of the limiting block is L-shaped.

[0013] The technical scheme is characterized in that: the swing arm is provided, and the swing arm is automatically turned down under the gravity of the counterweight after bending, so that the flexible pressing head can push the lead pin that does not completely droop to a vertical state and avoid pressing the lead pin; the L-shaped limiting block can accurately position the lead pin at a preset position to prevent rebound deviation. The flexible pressing head has weak magnetism, and the limiting block is made of iron material, which can further enhance the fixing effect of the lead pin, prevent the rebound, and ensure the accurate direction of the lead pin when the mechanical hand grabs, thereby significantly improving the success rate of subsequent insertion of the gasket.

[0014] The further improvement of the technical scheme is characterized in that: the mechanical hand includes a lifting cylinder fixedly installed on the top of the bottom plate, a rotating cylinder installed on the piston rod of the lifting cylinder, and an operating arm installed on the rotating part of the rotating cylinder, the operating arm is in an L-shaped structure, and two ends of the operating arm are respectively installed with a suction mechanism one for sucking the dry reed at the discharging device and a suction mechanism two for sucking the dry reed after shaping; the side of the operating arm close to the suction mechanism two is slidably connected with two slide rods, the bottom of the slide rods is fixedly connected with a pressing block, the top of the slide rods is extended to the upper side of the operating arm and fixedly connected with a backing plate, one side of the pressing block is fixedly connected with two anti-deviation blocks, and the outside of the slide rods is sleeved with a second spring.

[0015] The technical scheme is characterized in that: the slide rods and the pressing block with the second spring are provided on the operating arm, and the anti-deviation blocks are assisted to provide downward auxiliary pressure from the two sides of the lead pin during the lead pin pinching process, balance the reaction force of the gasket, and avoid the bending of the lead pin due to uneven unilateral stress; the pressing block is arranged in a structure that can be upwardly moved under pressure, so as to facilitate the taking of the dry reed without blocking the downward movement of the suction mechanism two.

[0016] The further improvement of the technical scheme of the present application is that the bottom of each of the two deviation preventing blocks is provided with a card hole with a diameter equal to that of the pin of the dry reed, and the position of the opening of the card hole is rounded, and the distance between the centers of the two card holes is equal to the distance between the bending positions of the two pins of the dry reed.

[0017] With the above technical scheme, the card holes at the bottom of the deviation preventing blocks are precisely matched with the diameter of the pins of the dry reed, and the distance between the centers of the card holes is consistent with the distance between the bending positions of the pins, so that the two card holes can be precisely clamped at the two corners of the U-shaped structure, effectively limiting the rotation of the dry reed around the bottom edge, and the restraining force can also prevent the dry reed from being bent towards the side to some extent, ensuring that each dry reed is inserted into the gasket in a unified posture and improving the neatness of the arrangement, and the rounding of the opening of the card hole can facilitate the entry of the pin. When the deviation preventing blocks are lowered to be attached to the pins of the dry reed, the card holes at the bottom of the two deviation preventing blocks are clamped at the two corner positions of the U-shaped dry reed, and since the diameter of the card holes is equal to that of the pins and the distance between the centers of the card holes is matched with the distance between the bending positions of the pins, the dry reed is circumferentially limited, preventing it from rotating around the bottom edge.

[0018] The further improvement of the technical scheme of the present application is that the limiting assembly comprises a fixed strip and a movable strip, the fixed strip is connected to one side of the top of the material receiving platform through a screw, one side of the fixed strip is fixedly connected with an L-shaped plate one, a plurality of waist-shaped grooves are formed in the movable strip, a mounting hole is formed in the material receiving platform, and the movable strip is installed by being connected with the mounting hole through a screw passing through the waist-shaped grooves; a threaded hole is formed in the movable strip, and a screw rod is threadedly connected to the threaded hole, an L-shaped plate two is slidably sleeved on the outside of the screw rod, and two nuts are connected to the outside of the screw rod, and the L-shaped plate two is fixed to the outside of the screw rod through the two nuts.

[0019] With the above technical scheme, the combination of the fixed strip and the movable strip provides a fixed positioning reference, the movable strip can adjust the horizontal position through the waist-shaped grooves, and the L-shaped plate two can adjust the vertical position through the screw rod and the nuts, so that the limiting assembly can be adapted to different sizes of trays without the need to replace the limiting components, thereby shortening the changeover time; the overall structure is accurately positioned, which can effectively limit the movement of the tray in the horizontal direction, ensuring the stability of the position of the tray when the material receiving platform moves, and ensuring the consistency of the arrangement of the dry reeds.

[0020] The further improvement of the technical scheme of the present application is that the top of the bottom plate is detachably connected with a spare material box, the side of the fixed strip away from the L-shaped plate one is fixedly connected with a material guide hopper, and the bottom of the material guide hopper is inclined.

[0021] Adopting the technical scheme, when the reed switch in the tray reaches the loading upper limit, the biaxial servo module drives the receiving platform to move, so that the tray deviates from the unloading position of the mechanical hand, at this time, the shaped reed switch grabbed by the mechanical hand falls into the guide hopper when falling, since the bottom of the guide hopper is arranged in an inclined manner, the reed switch slides along the hopper wall under the action of gravity, and finally enters the standby magazine detachably connected to the bottom plate, so that temporary collection of the reed switch is realized, and after the tray is replaced, the receiving platform is reset to continue normal collection. In addition, during production, the reed switch that does not need special arrangement protection can also be directly collected by using this method, and the original production will not be affected.

[0022] Further improvement of the technical scheme of the present application is that the gasket is an anti-static foam with a closed cell structure, and the Shore hardness range is 10-25A.

[0023] Adopting the technical scheme, the gasket is an anti-static foam with a closed cell structure, the dense closed cell structure in the gasket can effectively block static conduction, so that the friction electrification voltage is controlled in a low range, and the influence of static electricity on the reed switch is avoided. The softness of the Shore hardness 10-25A allows the reed switch pin to easily penetrate into the gasket, and the elastic recovery force of the foam can wrap the pin to form a stable fixing effect; the thickness design of the gasket ensures that the pin bending part is completely embedded, and the closed cell structure effectively isolates external vibration and collision, protecting the glass package and internal structure of the reed switch from damage.

[0024] Due to the adoption of the above technical scheme, the present application has the following technical effects compared with the prior art:

[0025] 1. The present application provides a reed switch shaping device, which realizes automatic matrix arrangement of the shaped reed switch through the controllable displacement of the receiving platform and the structural characteristics of the gasket; this scheme effectively solves the problem of chaotic accumulation, mutual collision and entanglement of reed switches caused by traditional collection methods, significantly reduces the risk of glass shell damage and pin deformation, and realizes the integration of shaping and orderly collection of the overall structure, without the need for manual secondary arrangement, while ensuring product quality and improving production continuity; at the same time, the neat matrix arrangement provides great convenience for subsequent warehousing, transportation and automatic assembly, greatly improving production efficiency and product reliability.

[0026] 2. This invention provides a reed switch forming device, which uses a bending cylinder to drive a forming boss to complete precise bending. After the bending cylinder resets, the forming boss automatically resets using a first spring. During the reset process, the vibration generated by the friction between the two sets of friction strips in the stroke area (this process also exists during the bending action, but does not occur during the bending process itself, but rather when the bending head approaches the pin, and will not affect the bending) can effectively release the pin from the jamming state of the die head, and assist the pins at both ends of the U-shaped reed switch (bent into a U-shape) to hang naturally, ensuring that the pin direction meets the gripping requirements.

[0027] 3. This invention provides a reed switch shaping device. By incorporating a swing arm, after bending, the swing arm automatically flips downwards under the weight of a counterweight. The flexible pressure head can push the not-fully-drooping pin to a vertical position while avoiding damage to the pin. Combined with an L-shaped limiting block, the pin can be precisely positioned in a preset location, preventing rebound and deviation. The flexible pressure head has weak magnetism, and the limiting block is made of iron, further enhancing the pin's fixing effect, preventing rebound, and ensuring accurate pin orientation when gripped by the robotic arm.

[0028] 4. By setting a slide bar with a second spring and a pressure block on the operating arm, and with the auxiliary support of the anti-deviation block, the anti-deviation block can provide downward auxiliary pressure from both sides of the pin during the pin insertion process, balancing the reaction force of the pad and preventing the pin from bending due to uneven force on one side. The clamp at the bottom of the anti-deviation block is precisely matched with the diameter of the reed switch pin, and the clamp spacing is consistent with the pin bending position. It can be accurately clamped at the two corners of the U-shaped structure, effectively restricting the rotation of the reed switch around the bottom edge. At the same time, its binding force can also prevent it from bending to the side to a certain extent, ensuring that each reed switch is inserted into the pad in a uniform posture, improving the neatness of the arrangement.

[0029] 5. Through the combination structure of fixed and movable bars, the fixed bar provides a fixed positioning reference, the movable bar can adjust the lateral position through the waist groove, and the L-shaped plate can adjust the longitudinal position through screws and nuts. It can adapt to pallets of different sizes without replacing the limiting parts, shortening the changeover time. The overall structure has precise positioning, which can effectively limit the movement of the pallet in the horizontal direction, ensure the stability of the pallet position when the receiving platform moves, and ensure the consistency of the reed switch arrangement.

[0044] The present invention will be further described in detail below with reference to the embodiments.

[0045] Example 1

[0046] like Figures 1-12 As shown, the present invention provides a reed switch shaping device, including a base plate 1, a feeding device 2, a robotic arm 3 for transferring reed switches, a positioning device 10, and a shaping device 5; it also includes: a dual-axis servo module 701, fixedly installed on the top of the base plate 1, with a receiving platform 702 fixedly connected to the movable end of the dual-axis servo module 701, the dual-axis servo module 701 being configured to drive the receiving platform 702 to perform high-precision displacement in two mutually perpendicular directions in the horizontal plane; a tray 8, placed on the top of the receiving platform 702, with a pad 9 provided in its internal groove, the pad 9 being made of a puncture-resistant flexible cushioning material, the material being configured to allow the pins of the reed switch to be inserted and held in place, the thickness of the pad 9 being greater than the length of the bent portion of the reed switch pins; and a limiting component, disposed on the top of the receiving platform 702, used to limit the movement of the tray 8 relative to the receiving platform 702 in the horizontal direction.

[0047] The reed switch shaping device 5 also includes a control system, which is signal-connected to the dual-axis servo module 701, the robot arm 3 and the shaping device 5; the control system includes a parameter setting module, which is used to receive and store the matrix arrangement parameters set by the user. The parameters include the total number of rows, the total number of columns, the row spacing and the column spacing, and each parameter can be adjusted independently.

[0048] The control system is configured to: after the shaping device 5 completes the pin shaping of the reed switch, call the currently set matrix arrangement parameters in real time, coordinate the control of the robot arm 3 to grab the shaped reed switch, and synchronously control the dual-axis servo module 701 to perform adaptive step displacement according to the set row spacing and column spacing, so as to insert the reed switch one by one and accurately into the corresponding target position on the pad 9, forming a neat matrix arrangement that meets the user requirements.

[0049] This solution, without adding any steps to the traditional shaping process, achieves automatic matrix arrangement of shaped reed switches through the controllable displacement of the receiving platform 702 and the structural characteristics of the gasket 9. This solution effectively solves the problems of messy stacking, collision and entanglement of reed switches caused by traditional collection methods, significantly reducing the risk of glass shell breakage and pin deformation. The overall structure integrates shaping and orderly collection, eliminating the need for secondary manual sorting, and improving production continuity while ensuring product quality. At the same time, the neat matrix arrangement provides great convenience for subsequent warehousing, transportation and automated assembly, greatly improving production efficiency and product reliability.

[0050] During operation, after completing the traditional feeding, transfer, positioning and shaping process, the receiving platform 702 is driven by the dual-axis servo module 701 to perform high-precision displacement in two mutually perpendicular directions in the horizontal plane. When the robot arm 3 moves the reed switch with the bent pins to the tray 8, the support height formed by the thickness of the pad 9 allows the reed switch pins to be inserted into the pad 9 and fixed during the single vertical descent action of the robot arm 3. At the same time, the limiting component ensures the positioning stability of the tray 8 in the horizontal direction, so that each reed switch can be accurately placed in the predetermined matrix position.

[0051] Preferably, the feeding device 2 includes a slide, a preparation tray at the upper end of the slide, and a feeding channel at the lower end of the slide. The feeding channel is a magnetically levitated feeding channel, which includes two fixed material plates, a magnetic plate adsorbed on the outer side of the fixed material plates, and a reinforcing magnetic block adsorbed on the middle of the outer side of the magnetic plate. The magnetic plate is 100×50×5mm in size, and the reinforcing magnetic block has a diameter of 15mm and a thickness of 3mm. The distance between the two fixed material plates is 45mm, which is 2-5mm longer than the length of the reed switch. A support is provided at the lower part of the preparation tray, and a pulley is installed at the lower end of the support. The support includes a central support column, three support rods connected to the lower part of the central support column, and auxiliary support rods connecting each support rod to the central support column. The slide includes an inclined sliding plate and baffle plates on both sides of the sliding plate. An auxiliary sliding plate is provided at the end of the sliding plate to facilitate the feeding of the reed switch into the feeding channel. The auxiliary sliding plate is horizontally set, and auxiliary baffle plates are erected on both sides of the auxiliary sliding plate. The auxiliary sliding plate corresponds to the feeding channel. The auxiliary slide plate corresponds to the middle of the feed channel. The auxiliary slide plate and the slide plate are made of the same material, SUS stainless steel. The auxiliary slide plate and the slide plate are welded and fixed together. The surface of the auxiliary slide plate has multiple raised ribs that are set along the material feeding direction and are parallel to each other. The function of the raised ribs is to guide the material.

[0052] Preferably, the positioning device 10 includes two centering cylinders symmetrically fixedly installed on the top of the pad 501. Centering push heads are fixedly connected to the piston rods of the two centering cylinders. The two centering cylinders operate synchronously to push the reed switch to the center position for bending.

[0053] Example 2

[0054] like Figure 3 , Figure 4 and Figure 5As shown, on the basis of embodiment 1, the application provides a technical scheme: preferably, the shaping device 5 comprises a cushion 501 fixedly connected to the top of the bottom plate 1, the top of the cushion 501 is fixedly connected with a sliding rail 502, the sliding rail 502 is slidingly connected with a shaped boss 503, a clearance slot 507 is formed in the central position of the bottom of the shaped boss 503, the top of the bottom plate 1 is fixedly connected with a bending cylinder 504, the piston rod of the bending cylinder 504 is fixedly connected with a push block 514, the push block 514 is in contact with the shaped boss 503; the top of the bottom plate 1 is fixedly connected with a fixed plate 508 at the position where the clearance slot 507 is located, the first spring 509 is fixedly connected between the fixed plate 508 and the shaped boss 503, the side of the shaped boss 503 away from the bending cylinder 504 is connected with two bending heads 510 through screws; the top of the bottom plate 1 is fixedly connected with a fixed block 505, two die heads 506 are connected to the top of the fixed block 505 through screws at the central position, and the side of each die head 506 close to the shaped boss 503 is fixedly connected with a placing block 511; the top of the fixed block 505 and the top of the inner wall of the clearance slot 507 are both provided with an avoiding slot 512, and the inside of the avoiding slot 512 is fixedly connected with a friction strip 513, the outer surface of the friction strip 513 is ground, and the sides of the two friction strips 513 close to each other are in contact with each other.

[0055] In the above scheme, the shaped dry reed pins need to be accurately inserted into the gasket 9 of the tray 8, which requires that the pins must be kept in a downward state during suction. However, after being bent by the existing shaping device 5, the dry reed pins are prone to direction deviation due to material springback or jamming. Since the metal pins have a tendency of elastic springback after being bent, they may be slightly jammed with the die head 506 or the placing block 511, and cannot naturally droop. If they are directly grabbed, the pins may be bent, broken or unable to be inserted into the gasket 9, affecting the smoothness of the subsequent collection process.

[0056] In this embodiment, the shaped boss 503 is driven by the bending cylinder 504 to complete precise bending, and after the bending cylinder 504 is reset, the automatic reset of the shaped boss 503 is realized by the springback of the first spring 509. During the reset process, the vibration generated by the mutual friction of the two groups of friction strips 513 in the stroke part area (this process also exists when the bending action is performed, but it does not exist in the bending process, but in the process of the bending head 510 approaching the pin, which does not affect the bending), which can effectively eliminate the jamming state of the pins and the die head 506, and assist the natural droop of the pins at both ends of the U-shaped dry reed (bent into a U shape), ensuring that the direction of the pins meets the grabbing requirements.

[0057] As shown in Figure 10 Further, the side of the fixed plate 508 away from the first spring 509 is fixedly connected with two top pins 13; the top pins 13 can assist in positioning the glass tube part of the dry reed during the bending process, avoiding damage to the glass tube caused by bending force transmission, and the overall structure takes into account the shaping accuracy and the reliability of the pin orientation.

[0058] As Figure 3 , Figure 4 and Figure 5 shown, wherein, Figure 3 shows the state of the dry reed before bending is placed in the bending position, Figure 4 shows the state during bending (profile of the forming boss 503), Figure 5 is the state after bending; during bending, the dry reed is fixed by the positioning device 10, the piston rod of the bending cylinder 504 is extended, the push block 514 is driven to drive the forming boss 503 to slide along the slide rail 502 to the direction of the die head 506, the bending head 510 on one side of the forming boss 503 cooperates with the die head 506 to bend the dry reed pin into a predetermined shape, after the bending is completed, the piston rod of the bending cylinder 504 is retracted, the forming boss 503 is reversely slid under the elastic force of the first spring 509 Reset, during this process, the two friction strips 513 rub against each other to generate vibration, which is transmitted to the dry reed on the placing block 511, prompting the stuck pin to swing downward, and during the travel except this position, the friction strip 513 is directly opposite the position where the avoidance groove 512 is located, so no vibration is generated.

[0059] Example 3

[0060] As Figure 10 , Figure 11 shown, on the basis of example 2, the application provides a technical solution: preferably, the side away from each other of the two die heads 506 is hingedly connected with a swing arm 601, the bottom end of the swing arm 601 is fixedly connected with a flexible pressure head 602, and the end of the swing arm 601 close to the flexible pressure head 602 is further fixedly connected with a counterweight 603; the end of the bending head 510 is fixedly connected with a top block 605, the end away from the bending head 510 of the top block 605 is rotatably connected with a roller 606, the roller 606 is in contact with the swing arm 601; the side close to the placing block 511 of the die head 506 is fixedly connected with a limiting block 604, the top view of the limiting block 604 is L-shaped.

[0061] The limiting block 604 and the flexible pressure head 602 of the swing arm 601 vertically downward are at the same height, the acting force of the two on the pin is at the same position in the axial direction, which will not cause the pin to bend.

[0062] Although the dry reed pin can swing downward, due to the continuous and fast production process, the pin is prone to shaking back and forth after vibration, which may cause the pin to be skewed (not directly below), at this time, the mechanical hand 3 will cause the pin to be offset when inserted into the gasket 9, even cause the pin to be bent or the glass tube to be damaged by collision, affect the product qualification rate and collection efficiency;

[0063] In the embodiment, by arranging the swing arm 601, the swing arm 601 is automatically turned down under the gravity of the counterweight 603 after being bent, the flexible pressing head 602 can push the pin that is not completely drooping to the vertical state, and can also avoid crushing the pin; cooperating with the L-shaped limiting block 604 can accurately position the pin at the preset position, and prevent the pin from being offset due to rebounding. Wherein, the flexible pressing head 602 has weak magnetism, and the limiting block 604 is made of iron material, which can further enhance the fixing effect of the pin, prevent the pin from rebounding, ensure the accurate direction of the pin when the mechanical hand 3 is grasped, and significantly improve the success rate of subsequent insertion into the gasket 9.

[0064] When being bent, the forming boss 503 drives the bending head 510 to move, the top block 605 at the end of the bending head 510 moves together, the roller 606 on the top block 605 contacts the swing arm 601 and pushes the swing arm 601 to swing upward around the hinge point, so that the flexible pressing head 602 is away from the area of the die head 506 and does not hinder the pin from being bent, after the bending is completed, the forming boss 503 is reset, the roller 606 is separated from the swing arm 601, the swing arm 601 swings downward under the gravity of the counterweight 603, the flexible pressing head 602 is pressed on the reed pin, the inclined pin is pushed to the vertical direction, and the L-shaped limiting block 604 cooperates to form a limiting space, so that the pin is fixed at the position and prevents the pin from being offset due to rebounding or shaking.

[0065] Embodiment 4

[0066] As shown in Figure 2 , Figure 6 and Figure 7 , on the basis of embodiment 3, the application provides a technical solution: preferably, the mechanical hand 3 comprises a lifting cylinder 301 fixedly installed on the top of the bottom plate 1, a rotating cylinder 302 installed on the piston rod of the lifting cylinder 301, and an operating arm 303 installed on the rotating part of the rotating cylinder 302, the operating arm 303 is in L-shaped structure, and two ends of the operating arm 303 are respectively provided with a suction mechanism one 304 for sucking the reed of the feeding device 2 and a suction mechanism two 305 for sucking the reed after being shaped; two slide rods 401 are slidably connected to one side of the operating arm 303 close to the suction mechanism two 305, a pressing block 402 is fixedly connected between the bottoms of the slide rods 401, the tops of the slide rods 401 are extended to the upper side of the operating arm 303 and are fixedly connected with a backing plate 406, two anti-deviation blocks 403 are fixedly connected to one side of the pressing block 402, and the second spring 405 is sleeved outside the slide rod 401.

[0067] Based on the above scheme, after the mechanical hand 3 grasps the reed, the pin needs to be inserted into the gasket 9, the existing grasping structure usually only provides suction force through the middle suction mechanism, and lacks support on both sides when the pin is inserted, so that the pin is easily bent upward and damaged due to the reaction force of the gasket 9, which affects the product quality and is contrary to the original intention of shaping;

[0068] In the embodiment, by setting the slide rod 401 with the second spring 405 and the pressing block 402 on the operating arm 303, cooperating with the auxiliary support of the anti-deviation block 403, the anti-deviation block 403 can provide downward auxiliary pressure from both sides of the pin during the pin insertion process, balance the reaction force of the gasket 9, and avoid the bending of the pin due to uneven force on one side; the pressing block 402 is set to be upwardly movable under pressure, aiming to facilitate the taking of the dry reed without blocking the downward movement of the suction mechanism two 305.

[0069] During operation, the lifting cylinder 301 drives the operating arm 303 to move up and down, and the rotating cylinder 302 drives the operating arm 303 to rotate, realizing the position switching of the suction mechanism one 304 and the suction mechanism two 305. The suction mechanism one 304 sucks the dry reed to be shaped from the material placing device 2, and the suction mechanism two 305 grabs the shaped dry reed. During the process, the pressing block 402 is upwardly movable under the reaction force of the die 506, compresses the second spring 405, and resets the pressing block 402 under the action of the second spring 405 when the shaped dry reed is taken and moved upward, so that the anti-deviation block 403 abuts against the pin of the dry reed and can provide auxiliary support. In this state, the second spring 405 is in an undeformed state or a slightly compressed state, and will not provide excessive pressure to avoid deforming the pin of the dry reed. When there is a deformation trend during the pin insertion process, the above-mentioned support force will balance it, thereby solving the problem of bending damage of the dry reed on both sides in the solution. Specifically, when the suction mechanism two 305 carries the dry reed to move to the tray 8, the pressing block 402 descends with the operating arm 303, and the anti-deviation block 403 abuts against both sides of the pin. During the pin insertion process, the slide rod 401 slides along the operating arm 303, the second spring 405 is compressed and generates an elastic force downward, which is transmitted to the anti-deviation block 403 through the pressing block 402, so that the anti-deviation block 403 applies auxiliary pressure to both sides of the pin, ensuring that the pin is inserted into the gasket 9 stably and evenly.

[0070] Preferably, the suction mechanism (suction mechanism one 304 and suction mechanism two 305) comprises a suction cylinder, a suction head connected to the end of the piston rod of the suction cylinder, and an adapter sleeve fitted on the end of the cylinder barrel of the suction cylinder. The suction head is a stepped structure comprising a large head portion and a small head portion connected to the large head portion, and the end of the large head portion of the suction head has a threaded hole matched with the piston rod, and the end of the small head portion of the suction head has a magnet. The adapter sleeve is a stepped sleeve structure comprising a large sleeve, a middle sleeve, and a small sleeve, and the inner cavity of the adapter sleeve is a stepped cavity comprising a large step, a middle step, and a small step. The large step is connected to the end of the cylinder barrel of the suction cylinder, the large head portion of the suction head is placed at the middle step of the inner cavity of the adapter sleeve, the small head portion of the suction head is placed at the small step of the inner cavity of the adapter sleeve, and the middle step and the small step are limited by a limiting surface for limiting the stroke of the suction head of the suction cylinder, so as to avoid direct contact between the suction head and the dry reed and damage to the dry reed. When the dry reed is sucked, the piston rod is extended, the suction head reaches the position between the middle step and the small step, and the dry reed is sucked; when the dry reed is released, the piston rod is retracted, the suction head is away from the dry reed, the dry reed is released, and the end of the adapter sleeve has a positioning groove for positioning the dry reed to be sucked. When the piston rod of the suction cylinder is extended, the magnet at the end of the small head portion of the suction head is located in the adapter sleeve (for specific forms and arrangements of various features, refer to the suction mechanism in CN111360176B).

[0071] As shown in Figure 6 , Figure 7 and Figure 12 , in the present embodiment, preferably, the bottom of each of the two anti-deviation blocks 403 is provided with a bayonet 404 with a diameter equal to that of the pin of the dry reed, and the opening of the bayonet 404 is rounded. The distance between the middle portions of the two bayonets 404 is equal to the distance between the bent positions of the two pins of the dry reed.

[0072] Although the scheme can provide auxiliary support on both sides, the dry reed has a U-shaped structure, and if it is not firmly adsorbed during insertion, it may be deviated around the bottom edge or even fall off, and the pin may be bent towards the side (the direction is perpendicular to the three edges of the U-shaped structure), which may cause the pin insertion position to deviate, affect the neatness of the matrix arrangement, and require additional adjustment during subsequent assembly, thereby reducing production efficiency.

[0073] In this embodiment, the locking slots 404 at the bottom of the anti-deviation block 403 precisely match the diameter of the reed switch pins, and the spacing between the locking slots 404 is consistent with the pin bending position. This allows them to precisely lock at the two corners of the U-shaped structure, effectively restricting the rotation of the reed switch around the bottom edge. Simultaneously, their binding force can also prevent lateral bending to a certain extent, ensuring that each reed switch is inserted into the pad 9 in a uniform posture, improving the neatness of the arrangement. The rounded corners of the locking slots 404 further facilitate pin insertion. When the anti-deviation block 403 descends with the pressure block 402 to adhere to the reed switch pins, the locking slots 404 at the bottom of the two anti-deviation blocks 403 precisely engage at the two corners of the U-shaped reed switch. Since the diameter of the locking slots 404 is equal to the pin diameter, and the spacing between the locking slots 404 matches the pin bending position distance, a circumferential limit is formed on the reed switch, preventing it from rotating around the bottom edge.

[0074] Example 5

[0075] like Figure 1 and Figure 8 As shown, based on Embodiment 4, the present invention provides a technical solution: Preferably, the limiting component includes a fixed strip 703 and a movable strip 705. The fixed strip 703 is connected to one side of the top of the receiving platform 702 by screws, and an L-shaped plate 704 is fixedly connected to one side of the fixed strip 703. The movable strip 705 has several waist-shaped grooves 706, and the receiving platform 702 has mounting holes. The movable strip 705 is installed by screws passing through the waist-shaped grooves 706 and connecting to the mounting holes. The movable strip 705 has threaded holes, and a screw 707 is threadedly connected to the threaded holes. An L-shaped plate 708 is slidably sleeved on the outside of the screw 707. Two nuts 709 are connected to the outside of the screw 707, and the L-shaped plate 708 is fixed to the outside of the screw 707 by the two nuts 709.

[0076] In actual production, it may be necessary to adapt to different sizes of trays 8 (such as loading different quantities or models of reed switches). The existing fixing method cannot flexibly adjust the limit range. If the tray 8 is replaced, the limit components need to be customized again, resulting in long changeover time and affecting production efficiency. Moreover, the lack of a unified positioning benchmark can easily lead to the installation of tray 8 offset, affecting the arrangement accuracy of the reed switches.

[0077] In this embodiment, the combination structure of the fixed strip 703 and the movable strip 705 provides a fixed positioning reference. The movable strip 705 can be adjusted in the lateral position through the waist-shaped groove 706. The L-shaped plate II can be adjusted in the longitudinal position through the screw 707 and the nut 709. It can adapt to pallets 8 of different sizes without replacing the limiting parts, thus shortening the changeover time. The overall structure is accurately positioned and can effectively limit the movement of the pallet 8 in the horizontal direction, ensuring that the position of the pallet 8 is stable when the receiving platform 702 moves, and ensuring the consistency of the reed switch arrangement.

[0078] The fixed strip 703 is fixed on one side of the top of the material receiving platform 702 by a screw, and an L-shaped plate I is formed on one side of the fixed limiting reference. The movable strip 705 is connected with the mounting hole of the material receiving platform 702 by a screw passing through the waist-shaped groove 706, and the horizontal position of the movable strip 705 can be adjusted by loosening the screw; the screw rod 707 on the movable strip 705 is in sliding cooperation with the L-shaped plate II, and the longitudinal position of the L-shaped plate II can be fixed by adjusting the position of the two nuts 709 on the screw rod 707, so as to form a limiting space suitable for the size of the tray 8 in cooperation with the L-shaped plate I, and the precise limiting of the tray 8 of different sizes is realized.

[0079] As shown in Figure 1 , Figure 2 and Figure 8 , preferably, the top of the bottom plate 1 is detachably connected with a spare box 11, and the side away from the L-shaped plate I 704 of the fixed strip 703 is fixedly connected with a guide hopper 12, and the bottom of the guide hopper 12 is inclinedly arranged.

[0080] In the above scheme, when the grommet 9 in the tray 8 is inserted into the dry reed tube, the tray 8 needs to be replaced, which causes the production to be interrupted and the overall production efficiency to be reduced; if the dry reed tube is temporarily stacked, the problem of disorder and collision will occur, which affects the product quality.

[0081] In the embodiment, when the dry reed tube in the tray 8 reaches the upper limit of loading, the double-shaft servo module 701 drives the material receiving platform 702 to move, so that the tray 8 deviates from the discharging position of the mechanical arm 3; at this time, the dry reed tube grabbed by the mechanical arm 3 after being shaped falls into the guide hopper 12, and since the bottom of the guide hopper 12 is inclinedly arranged, the dry reed tube slides along the hopper wall under the action of gravity and finally enters the spare box 11 detachably connected to the bottom plate 1, so that the temporary collection of the dry reed tube is realized; after the replacement of the tray 8 is completed, the material receiving platform 702 is reset to continue normal collection. In addition, during the production process, the dry reed tube which does not need special arrangement protection can also be directly collected by using this method, and the original production will not be affected.

[0082] Preferably, the grommet 9 is an anti-static foam with a closed cell structure, and the Shore hardness thereof ranges from 10 to 25A.

[0083] In the embodiment, the grommet 9 is an anti-static foam with a closed cell structure, and the internal dense closed cell structure can effectively block the static conduction, so that the friction electrification voltage is controlled in a low range, and the influence of static electricity on the dry reed tube is avoided. The softness of the Shore hardness of 10-25A makes the dry reed tube pin easily penetrate into the inside of the grommet 9, and the elastic recovery force of the foam can wrap the pin to form a stable fixing effect; the thickness design of the grommet 9 ensures that the pin bending part is completely embedded, and in combination with the buffering effect of the closed cell structure, external vibration and collision are effectively isolated, so that the glass package and internal structure of the dry reed tube are protected from damage.

[0084] The above detailed description of the present application is general, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the present application are within the scope of the present application.
