Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically relating to an automated spring connecting line production equipment. Background Technology

[0002] Test fixture spring wires are conductors made by welding precision probe springs onto stripped and tested wires. They are key consumables in PCB test fixtures, mainly used in the later stages of circuit board production to detect short circuits or open circuits. The production process involves several key steps: First, the cutting process cuts the coiled wires to specific lengths to meet the different length requirements of various electronic products; next, the wire stripping process removes the insulation from both ends of the wire to expose the internal conductor for subsequent soldering; then comes the soldering process, including soldering the springs individually and soldering the springs together with the stripped wires to achieve a reliable electrical connection; finally, the tubing process inserts multiple soldered spring wires into a tubing to complete the production of the spring wires.

[0003] However, existing spring wire production relies heavily on manual labor in each stage, which has many drawbacks. Manual cutting makes it difficult to ensure precise and consistent cut lengths; deviations in wire length can affect subsequent assembly and the performance of electronic products. Wire stripping is inefficient by hand, making it unsuitable for large-scale production, and poor control over force and depth can reduce product quality stability. The soldering process requires high levels of worker skill and experience; manual soldering is slow, and quality is affected by worker condition and skill, easily leading to defects such as incomplete soldering and missing solder, reducing product reliability. Finally, in the process of inserting multiple wires into the tubing, manual operation makes it difficult to ensure accurate wire quantity, is slow, and can also cause twisting or tangling of the finished product due to improper handling, affecting product quality.

[0004] With the continuous increase in demand in the electronics market, higher requirements are being placed on the output and quality of spring wires. Traditional manual production methods are inefficient, costly, and produce inconsistent product quality, making them unable to meet the high-efficiency and high-precision production needs of modern electronics manufacturing. Utility Model Content

[0005] The purpose of this invention is to provide an automated spring wire production equipment, which aims to solve the technical problems of low efficiency, high cost and unstable quality caused by the fact that spring wire production in the prior art mainly relies on manual production.

[0006] To achieve the above objectives, this utility model provides an automated spring wire production equipment, including a straightening device for straightening the wire, a rear stripping device and a front stripping device for stripping the wire ends, a wire cutting device for cutting the wire, a front clamping device that can move the wire, a feeding device for conveying the spring and the rubber ring, a spring clamping device for clamping the spring, a soldering device for soldering the spring and the wire, and a ring-closing device for completing the sleeve process.

[0007] The above-mentioned technical solutions of one or more technical solutions in the automated spring wire production equipment provided by this utility model embodiment have at least one of the following technical effects:

[0008] This utility model discloses an automated spring wire production equipment. With the cooperation of a rear stripping device, a wire cutting device, a front stripping device, and a front clamping device, it can straighten and cut the coiled wire to a set length. Furthermore, with the cooperation of the front stripping device, the rear stripping device, and the cutting device, the wire ends on both sides of the cutting device are stripped. This achieves automatic wire cutting and stripping, greatly improving the efficiency of wire cutting and stripping, and significantly enhancing processing accuracy. It ensures that the length of each wire is consistent, and the stripping depth and length can be precisely controlled, reducing product quality problems caused by differences in manual operation, improving product quality stability, and reducing the defect rate.

[0009] This utility model discloses an automated spring wire production equipment. With the cooperation of a feeding device and a spring clamping device, the spring is accurately clamped by the spring clamping mechanism. Under the clamping of the front stripping device and the front wire clamping device, the cut and stripped wire is moved to the pre-insertion mechanism in the soldering device. With the cooperation of the spring clamping mechanism, the pre-insertion mechanism, and the front wire clamping device, the spring is inserted into the stripped wire, completing the spring insertion process. The automated operation makes the spring insertion process more precise and efficient, reducing potential positional deviations or incomplete insertions that may occur with manual spring insertion, thus improving the assembly quality of the semi-finished spring wire. Simultaneously, automated operation reduces manpower input and lowers labor costs.

[0010] This utility model discloses an automated spring wire production equipment. With the cooperation of a front clamping device, a rotating clamping mechanism, and a spring clamping device, the wire inserted into the spring is moved to the soldering area. The wire is fixed by a roller mechanism, a rotating clamping mechanism, and a spring clamping mechanism. The soldering connection mechanism completes the soldering connection between the spring and the wire. The stable fixing mechanism ensures that the wire and the spring will not be displaced during the soldering process, thus guaranteeing the soldering quality, reducing welding defects such as cold solder joints and missing solder joints, and improving the electrical performance and reliability of the product.

[0011] This utility model discloses an automated spring wire production equipment. With the cooperation of a feeding device and a ferrule device, multiple welded spring wires are collected into one strand. Under the action of the ferrule displacement unit, the wire moves to the left and passes through the rubber ring, completing the ferrule process. This realizes the automation of the ferrule process, improves the efficiency and quality of ferrule production, reduces problems such as wire twisting, tangling, or difficulty in rubber ring insertion caused by improper manual operation, and improves the overall quality and appearance of the product.

[0012] This utility model discloses an automated spring wire production equipment that automates the entire spring wire production process. From wire cutting and stripping to spring insertion, soldering, and the final sleeve process, each step works in close coordination. This not only significantly improves production efficiency and reduces labor costs but also substantially enhances product quality stability and consistency, effectively reducing the defect rate. Automated production reduces the uncertainty and errors caused by manual operation, making the production process more controllable, ensuring product quality, enhancing product competitiveness in the market, and bringing higher economic benefits to the enterprise.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0055] In one embodiment of this utility model, such as Figure 1 As shown, an automated spring wire production equipment is provided, including a straightening device 10, a post-stripping device 20, a wire cutting device 30, a front wire clamping device 40, a front stripping device 50, a feeding device 60, a spring clamping device 70, a soldering device 80, and a ring-forming device 90.

[0056] The straightening device 10 is a roller-type wire straightener. Multiple annular grooves are provided on the rollers. Multiple wires enter from the right end of the straightening device 10 and exit from the left end of the straightening device 10 through the annular grooves on the rollers. A rear stripping device 20 is located on the left side of the straightening device 10. A wire cutting device 30 is located to the left of the rear stripping device 20, and a front clamping device 40 is located to the left of the wire cutting device 30. The front clamping device 40 has multiple driving sliding units, allowing it to move along the X and Y axes. A front stripping device 50 is located at the end of the front clamping device 40 closest to the wire cutting device 30. The wire passes through the straightening device 10, the rear stripping device 20, the wire cutting device 30, and the front stripping device 50. After the front clamping device 40 pulls the wire to a set length, the wire cutting device 30 cuts the wire. The wire cutting device 30 descends, and the rear stripping device 20, the front clamping device 40, and the front stripping device 50 move the wire left and right, stripping the wire ends on both sides of the wire cutting device 30.

[0057] The front clamping device 40 works in conjunction with the front stripping device 50 to clamp and fix the cut and stripped wires, and moves along the X-axis to move the cut and stripped wires into the soldering device 80.

[0058] A spring clamping device 70 is provided behind the stripping device 20. A feeding device 60 and a soldering device 80 are provided on the left side of the spring clamping device 70, and the soldering device 80 is located in front of the feeding device 60. A ring-closing device 90 is provided on the left side of the soldering device 80. The feeding device 60 transports the springs and rubber rings required for producing the spring connection line to the picking positions of the spring clamping device 70 and the ring-closing device 90. After the spring clamping device 70 clamps the spring, it moves the spring into the soldering device 80. The soldering device 80 performs soldering operations on the spring, and the ring-closing device 90 clamps and fixes the rubber ring.

[0059] The soldering device 80, spring clamping device 70, front wire clamping device 40, and rear stripping device 50 cooperate to move the wire so that the end of the wire to be connected to the spring is inserted into the soldering device 80. The soldering device 80 helps to fix the position of the wire. The spring clamping device 70 moves the spring to insert it into the soldering device 80, so that the spring is sleeved on the wire. The front wire clamping device 40 cooperates with the collar device 90 to shift the wire after it has been inserted into the spring, so that the wire after it has been inserted into the spring is moved into the collar device 90.

[0060] like Figure 2As shown, the stripping device 20 includes: a cylinder sliding mechanism 21, a cylinder gripper 22, a chuck 23, and a wire block 24. The cylinder sliding mechanism 21 converts the rotational motion of the servo motor into linear motion, achieving high-precision linear positioning and motion control via a slide rail. A slider is provided in the cylinder sliding mechanism 21, which is connected to the cylinder gripper 22, thereby enabling the cylinder gripper 22 to move left and right. Under the clamping action of the cylinder gripper 22 on the wire, the wire is stripped. The cylinder gripper 22 can open and close the chuck 23. A wire block 24 is fixedly mounted on the cylinder gripper 22. The wire block 24 is U-shaped, and the chuck 23 is located in the middle gap of the wire block 24, allowing the wire to first pass through one end of the wire block 24, enter the chuck 23, and then pass through the other end of the wire block 24. The wire block 24 provides support and limits the wire.

[0061] The clamp 23 includes an upper clamp 231 and a lower clamp 232. The upper clamp 231 and the lower clamp 232 open and close under the drive of a cylinder to clamp and release the wire.

[0062] like Figure 3 As shown, the upper clamp 231 is provided with a notch 2311, a groove 2312, and a baffle 2313. The notch 2311 is trapezoidal and evenly distributed on the left and right sides of the upper clamp 231. A groove 2312 perpendicular to the wire is formed in the middle of the upper clamp 231. A baffle 2313 parallel to the groove 2312 is provided between the groove 2312 and the notch 2311. A flexible pad, such as a rubber block, is provided in the groove 2312. The thickness of the flexible pad is greater than the depth of the groove 2312. When the upper clamp 231 and the lower clamp 232 clamp the wire, the flexible pad can prevent the wire from being crushed.

[0063] like Figure 4 As shown, the lower clamp 232 is provided with a protrusion 2321, which is trapezoidal and has a wire limiting groove between it. When the upper clamp 231 and the lower clamp 232 clamp the wire, the protrusion 2321 extends into the notch 2311, and the upper clamp 231 presses the wire into the corresponding wire limiting groove, thereby achieving a stable clamping of the wire.

[0064] like Figure 5-6As shown, the wire cutting device 30 includes: a drive screw 31, an upper blade holder 32, a lower blade holder 33, an air inlet 34, a waste frame 35, and a blade holder lifting cylinder 36. The drive screw 31 is equipped with a servo motor, which drives the screw to rotate. The thread direction of the upper half of the drive screw 31 is opposite to that of the lower half. The upper blade holder 32 is fitted onto the upper half of the drive screw 31, and the lower blade holder 33 is fitted onto the lower half. The upper blade holder 32 is equipped with a cutting head for the cutting process and a serrated cutting head similar to that for the peeling process. The lower blade holder 33 is equipped with a cutting head that matches the cutting head on the upper blade holder 32. The wire can be cut by the contact of the two cutting heads.

[0065] The upper cutter holder 32 and the lower cutter holder 33 are connected to the drive screw 31 via threaded connections. When the drive screw 31 rotates clockwise, the upper cutter holder 32 and the lower cutter holder 33 come into contact, causing the cutter heads on the upper cutter holder 32 and the lower cutter holder 33 to contact each other, thus cutting the wire. When the drive screw 31 rotates counterclockwise, the upper cutter holder 32 and the lower cutter holder 33 separate. The upper cutter holder 32 is equipped with an air inlet 34, which blows out high-pressure gas to remove any remaining rubber that has not detached from the wire after the peeling process. A waste collection box is located below the air inlet 34 to collect the rubber that has been blown away by the air inlet 34.

[0066] The lower blade holder 33 is also equipped with a blade holder lifting cylinder 36 for adjusting the height of the blade holder. The blade holder lifting cylinder 36 is fixed to the platform below the wire cutting device 30. The blade holder lifting cylinder 36 is connected to the lower blade holder 33, and the lower blade holder 33 is connected to the upper blade holder 32 via a drive screw 31. This allows the blade holder lifting cylinder 36 to drive the lower blade holder 33 to rise and fall, which in turn drives the upper blade holder 32 to rise and fall. After the upper blade holder 32 descends, the serrated blade head contacts the wire, and the wire moves left and right to perform the wire stripping process.

[0067] like Figure 7 As shown, the front wire clamping device 40 includes: an X-axis drive slide rail 41, a front wire clamping jaw 42, a Z-axis drive screw 43, a fixed base 44, and an auxiliary slide rail 45. The X-axis drive slide rail 41 is located on the left side of the wire tangent device 30 and is arranged along the X-axis direction. The front wire clamping jaw 42 is connected to the rear of the X-axis drive slide rail 41, and the front wire clamping jaw 42 can move along the X-axis drive slide rail 41 under the driving action of the X-axis drive slide rail 41.

[0068] The Z-axis drive screw 43 is located on the left side of the tangent device 30 and is adjacent to the tangent device 30. The Z-axis drive screw 43 is provided with a fixed seat 44, and the fixed seat 44 is provided with an X-axis drive slide rail 41. The Z-axis drive screw 43 can drive the fixed seat 44 to drive the X-axis drive slide rail 41 to move back and forth along the Z-axis direction, so that the front wire clamping claw 42 can move along the X-axis and Z-axis under the driving action of the X-axis drive slide rail 41 and the Z-axis drive screw 43.

[0069] An auxiliary slide rail 45 is provided on the side of the Z-axis drive screw 43 away from the tangent device 30. The auxiliary slide rail 45 is located at the bottom of the X-axis drive slide rail 41 and serves to support the X-axis drive slide rail 41.

[0070] The front stripping device 50 also consists of a cylinder sliding mechanism 21, a cylinder gripper 22, and a chuck 23. The cylinder gripper 22 controls the chuck 23 to clamp the wire, and then the cylinder sliding mechanism 21 drives the cylinder gripper 22 to move towards the wire cutting device 30. The wire contacts the serrated blade, thus stripping the wire. The front stripping device 50 is mounted on a fixed base 44 and can move synchronously back and forth along the Z-axis direction with the front wire clamping gripper 42 under the drive of the Z-axis drive screw 43.

[0071] like Figure 1 As shown, the feeding device 60 includes: a spring feeding tray 61, a spring detection mechanism 62, a vibrating plate 63, and a rubber ring feeding tray 64. The spring feeding tray 61 is a vibrating feeding tray, which feeds the springs in the desired direction onto the conveying channel connected to the spring clamping device 70. The vibrating plate 63 is located below the conveying channel and is in contact with the conveying channel, so that the conveying channel conveys the springs into the spring clamping device 70 under the vibration of the vibrating plate 63.

[0072] The spring feeder 61 is equipped with a spring detection mechanism 62, which uses a vision inspection device to inspect the springs before they are conveyed to the transmission channel.

[0073] A rubber ring feeding plate 64 is provided on the left side of the spring feeding plate 61. The rubber ring feeding plate 64 is also a vibrating feeding plate. The rubber ring feeding plate 64 conveys the rubber ring that needs to be sleeved on the wire to the rubber ring picking port through the transmission channel in the required direction.

[0074] like Figure 8-9As shown, the spring clamping device 70 includes: a drive slide rail 71, a power unit 72, a spring clamp 73, and a detection device 74. The drive slide rail 71 is arranged parallel to the Z-axis drive screw 43. The power unit 72 is connected to the drive slide rail 71. The power unit 72 can be a telescopic cylinder or a servo motor, etc., which can drive the spring clamp 73 to reciprocate along the wire feeding direction. The power unit 72 moves along the Z-axis direction under the drive of the drive slide rail 71. The spring clamp 73 is connected to the power unit 72. The spring clamp 73 reciprocates along the wire feeding direction under the drive of the power unit 72. The spring clamp 73 is equipped with a cylinder, which can control the opening or closing of the clamp to clamp the spring. The detection device 74 is located on the left side of the rear end of the drive slide rail 71. The detection device 74 is an optical detection device. The spring feed tray 61 transports the springs to the detection device 74, and the detection device 74 detects information such as the number of springs.

[0075] like Figure 10 , 11 As shown, the spring gripper 73 consists of an upper gripper 731 and a lower gripper 732. The upper gripper 731 has a first limiting hole 7311, and the lower gripper 732 has a second limiting hole 7321. Both the first limiting hole 7311 and the second limiting hole 7321 are semi-circular grooves with the same diameter as the spring. When the upper gripper 731 and the lower gripper 732 are closed under the action of the power unit 72, the first limiting hole 7311 and the second limiting hole 7321 form a circular hole, which fixes the spring.

[0076] like Figure 8 As shown, the detection device 74 includes: a fixing mechanism 741, a lifting cylinder 742, and a detector 743. The fixing mechanism 741 is mounted on the lifting cylinder 742 and contains a cylinder. Under the driving action of the cylinder, the fixing mechanism 741 can fix the spring transported by the vibrating plate 63 and is lifted under the drive of the lifting cylinder 742. The detector 743 is located on the right side of the fixing mechanism 741. The detector 743 is provided with a support plate 7431 for supporting the spring. The top surface of the support plate 7431 has an upward-facing semi-circular groove that matches the diameter of the spring. A baffle is provided on the right side of the support plate 7431. The top surface of the baffle is on the same plane as the top surface of the support plate 7431. The groove and the baffle are used to limit the movement of the spring.

[0077] The fixing mechanism 741 includes: a support plate 7411, a clamping plate 7412, and a clamping cylinder 7413.

[0078] The top surface of the support plate 7411 is provided with an upward-facing semi-circular groove that matches the diameter of the spring. This groove is used to limit the spring. The bottom surface is connected to the top surface of the telescopic rod of the lifting cylinder 742. The lifting cylinder 742 can lift and lower the support plate 7411. When the lifting cylinder 742 is lowered, the top surfaces of the support plate 7411 and the support plate 7431 are on the same plane, and the upward-facing semi-circular grooves on the top surfaces of the support plate 7411 and the support plate 7431 are coaxial. This allows the spring transmitted from the vibrating plate 63 to fall into the top surfaces of the support plate 7411 and the support plate 7431 and be confined in the semi-circular groove.

[0079] like Figure 12 As shown, the soldering device 80 includes: a spring tin-brushing mechanism 81, a lifting screw 82, an upper plate 83, a lower plate 84, a solder connection mechanism 85, and a pre-insertion mechanism 86.

[0080] The spring soldering mechanism 81 is located in front of the detection device 74 and to the left of the spring clamping device 70. The spring soldering mechanism 81 is a roller-type soldering machine. A servo motor drives a roller with an annular groove in the solder paste tank to rotate, extending the spring into the annular groove of the roller, thus completing the soldering process on the spring. The spring soldering mechanism 81 can be freely added or omitted depending on the type of spring wiring and whether the spring requires soldering.

[0081] The spring soldering mechanism 81 is provided with a lifting screw 82 in front. The thread direction of the upper half of the lifting screw 82 is opposite to that of the lower half. The upper half of the lifting screw 82 is fitted with an upper plate 83, and the lower half is fitted with a lower plate 84. A soldering connection mechanism 85 and a pre-insertion mechanism 86 are provided between the upper plate 83 and the lower plate 84. The upper plate 83 and the lower plate 84 are connected to the lifting screw 82 by threaded connection. When the lifting screw 82 rotates clockwise, the upper plate 83 and the lower plate 84 come into contact, causing the soldering connection mechanism 85 and the pre-insertion mechanism 86 on the upper plate 83 and the lower plate 84 to close, thereby performing soldering and clamping actions respectively.

[0082] The soldering connection mechanism 85 closes through the closing action of the upper plate 83 and the lower plate 84, performing a soldering connection process on the wires and springs that extend into the soldering connection mechanism 85. The pre-insertion mechanism 86 closes through the closing action of the upper plate 83 and the lower plate 84, fixing the wires in the pre-insertion mechanism 86.

[0083] like Figure 12 , 13As shown, the pre-insertion mechanism 86 is composed of a top plate 861 and a bottom plate 862. The top plate 861 is fixed on the upper plate 83, and the bottom plate 862 is fixed on the lower plate 84. The bottom surface of the top plate 861 is provided with an auxiliary hole 8611, which is semi-conical in shape.

[0084] The top surface of the base plate 862 is provided with a wire passage hole 8621 and a spring passage hole 8622. The side of the wire passage hole 8621 into which the wire is inserted is semi-conical. After the top plate 861 contacts the base plate 862, the semi-conical part of the wire passage hole 8621 and the auxiliary hole 8611 form a complete cone shape. The cone tip of the wire passage hole 8621 passes through to form a wire hole. The diameter of the wire hole is the same as the diameter of the wire, allowing the wire to pass through the wire passage hole 8621 more smoothly. The spring passage hole 8622 is located to the right of the wire passage hole 8621. The wire passage hole 8621 and the spring passage hole 8622 are connected through each other, and the spring passage hole 8622 allows the spring to extend into it.

[0085] like Figure 15 , 16 As shown, the ring-feeding device 90 includes: a ring-feeding displacement unit 91, a mounting plate 92, a rotating clamping mechanism 93, a wire plate 94, a roller mechanism 95, a wire take-up mechanism 96, a rubber ring transfer mechanism 97, and a transmission device 98.

[0086] The ring moving unit 91 is located on the left side of the soldering device 80 along the X-axis. The ring moving unit 91 contains a drive motor and a mounting plate 92. Driven by the servo motor of the ring moving unit 91, the mounting plate 92 can reciprocate along the X-axis. The mounting plate 92 has a roller mechanism 95. A rotating clamping mechanism 93 is fixed to the right side of the roller mechanism 95. The rotating clamping mechanism 93 includes a cylinder and a clamping jaw controlled by the cylinder. A wire plate 94 is fixed to the left side of the rotating clamping mechanism 93 and is used to support the wire. The rotating clamping mechanism 93 can clamp and release the wire under the action of the cylinder-driven clamping jaw. A take-up mechanism 96 is located to the left of the roller mechanism 95. The take-up mechanism 96 contains a drive slide rail unit. Driven by the drive slide rail unit, the take-up mechanism 96 can move back and forth, providing space for the front wire clamping device 40 and the front stripping device 50 to transfer the wire to the roller mechanism 95 and the rotating clamping mechanism 93.

[0087] The roller mechanism 95 includes: a drive unit 951, an upper roller 952, a lower roller 953, and a roller cylinder 954. The drive unit 951 is a servo motor, which is connected to the upper roller 952 through a transmission assembly to drive the upper roller 952 to rotate. The lower roller 953 is located below the upper roller 952, and the upper roller 952 and the lower roller 953 are tangentially arranged. The lower roller 953 is connected to the roller cylinder 954 through a round rod and a connecting rod. The lower roller 953 is sleeved on the round rod. The lower roller 953 can rotate around the round rod under the rotation of the upper roller 952, and the lower roller 953 can open and close relative to the upper roller 952 under the drive of the roller cylinder 954.

[0088] The take-up mechanism 96 includes: a take-up cylinder 961, a slide rail 962, a horn unit 963, and a rubber ring hole 964. Two slide rails 962 are located below the take-up cylinder 961. The take-up cylinder 961 can drive the two slide rails 962 to move closer or separate simultaneously. A horn unit 963 is fixedly connected to the bottom surface of each slide rail 962. Each horn unit 963 is divided into two parts, each connected to a slide rail 962, allowing the horn unit 963 to be separated or integrated. The horn unit 963 is horn-shaped, with a larger opening at one end facing the upper roller 952, and a rubber ring hole 964 at the other end.

[0089] The rubber ring transfer mechanism 97 includes: a first cylinder 971, a second cylinder 972, and a picking cylinder 973. The first cylinder 971 is equipped with the second cylinder 972, which can drive the second cylinder 972 to move back and forth. The second cylinder 972 is equipped with the picking cylinder 973, which can drive the picking cylinder 973 to move towards the horn unit 963. The picking cylinder 973 is equipped with a picking rod, which drives the picking rod to insert into the rubber ring that is conveyed to the picking port by the rubber ring feeding plate 64, thereby realizing the picking action of the rubber ring. Driven by the first cylinder 971 and the second cylinder 972, the picking cylinder 973 transfers the rubber ring to the preset position. The picking cylinder 973 stops moving, keeping the rubber ring in the preset position. After the horn unit 963 moves to the preset position, it changes from a separated state to a closed state under the drive of the cylinder. The rubber ring hole 964 clamps the rubber ring, realizing the transfer action of the rubber ring.

[0090] Below the take-up mechanism 96 is a transmission device 98, which is a conveyor belt that can discharge the spring wire that falls onto the transmission device 98 after the roller mechanism 95 and the horn unit 963 in the take-up mechanism 96 are opened.

[0091] The working principle of this utility model is as follows: An automated spring wire production equipment, in use, first inserts the wire sequentially into the straightening device 10, the rear stripping device 20, and the front stripping device 50. The X-axis drive slide rail 41 drives the front wire clamping jaw 42 to move to the front stripping device 50, where the front wire clamping jaw 42 clamps the wire. Then, the X-axis drive slide rail 41 drives the front wire clamping jaw 42 to move to the left, pulling the wire to a set length. Next, the cylinder clamping jaw 22 in the rear stripping device 20 and the front stripping device 50 controls the chuck 23 to clamp the wire. The drive screw 31 drives the upper blade holder 32 to contact the lower blade holder 33, and the cutter heads on the upper blade holder 32 and lower blade holder 33 contact each other, performing a cutting process on the wire. Subsequently, the upper blade holder 32 and lower blade holder 33 move away from each other and reset. The blade holder lifting cylinder 36 then drives the lower blade holder 33... The upper blade holder 32 is lowered, bringing the serrated blade into contact with the wire. Then, the cylinder sliding mechanism 21 in the rear stripping device 20 drives the cylinder gripper 22 to move the chuck 23 to the left. At the same time, the front stripping device 50 and the front clamping device 40 move the wire to the left, so that the wire comes into contact with and moves against the serrated blade. The wire insulation that was originally on the right side of the cutting device 30 breaks. Then, the front stripping device 50 and the front clamping device 40 move the wire to the right, and the rear stripping device 20 drives the chuck 23 to move the wire to the right, so that the wire comes into contact with and moves against the serrated blade. The wire insulation that was originally on the left side of the cutting device 30 breaks, completing the wire stripping process. Under the action of the air nozzle 34, the wire insulation is blown away from the wire and falls into the waste box 35, completing the wire cutting and stripping process.

[0092] Meanwhile, the spring feeder 61 and the vibratory feeder 63 work together to feed the spring to the support plate 7411 and the support plate 7431. After the detector 743 detects that the spring is in place, the clamping cylinder 7413 drives the clamping plate 7412 to approach the support plate 7411 to fix the spring. Then, the lifting cylinder 742 lifts the fixing mechanism 741, leaving the right side of the spring suspended. The drive rail 71 drives the power unit 72 to drive the spring gripper 73 to grip the spring. Then, the spring gripper 73 drives the spring to move to the spring soldering mechanism 81. The power unit 72 drives the spring gripper 73 to insert the spring into the spring soldering mechanism 81 to complete the soldering work. Then, the power unit 72 drives the spring gripper 73 to reset. Then, the drive rail 71 drives the spring gripper 73 to move the spring forward to the right side of the pre-insertion mechanism 86. Subsequently, the Z-axis drive screw 43 drives the front wire clamping jaw 42 and the front stripping device 50 to move the cut and stripped wire to the pre-insertion mechanism 86, so that the end of the wire that needs to be inserted into the spring enters the wire through hole 8621. Then, the top plate 861 contacts the bottom plate 862. Then, the spring clamping jaw 73 moves towards the pre-insertion mechanism 86 under the action of the power unit 72, so that the spring enters the spring through hole 8622 and is sleeved on the wire.

[0093] Next, the pre-insertion mechanism 86 resets, releasing the wire and spring. The front wire clamping jaw 42, the front stripping device 50, and the spring clamping jaw 73 move backward. The lower roller 953 contacts the upper roller 952 under the action of the roller cylinder 954. The rotating clamping mechanism 93 closes, clamping the wire and completing the clamping of the wire. At this time, the soldering connection mechanism 85 performs a soldering process on the wire and the spring. The front stripping device 50 resets, and the front wire clamping jaw 42 resets.

[0094] While soldering, the rubber ring feeder 64 delivers the rubber ring to the right-side pick-up port of the rubber ring transfer mechanism 97. The pick-up cylinder 973 picks up the material. Then, the first cylinder 971 drives the second cylinder 972 to move the pick-up cylinder 973. The take-up cylinder 961 drives the slide rail 962 to close the speaker unit 963 and fix the rubber ring in the rubber ring hole 964 in the speaker unit 963. Then, the take-up mechanism 96 moves forward to align the speaker unit 963 with the wire. After the wire and spring are soldered, the spring clamp 73 resets. The ring displacement unit 91 drives the rotating clamp mechanism 93, the wire plate 94, and the roller mechanism 95 to move the wire and spring synchronously to the left. The wire eventually passes through the rubber ring via the horn unit 963. At this time, the rotating clamp mechanism 93 releases the wire, and the drive unit 951 drives the upper roller 952 to rotate, causing the wire to continue moving to the left until the spring approaches the roller 952. Then, the roller cylinder 954 causes the lower roller 953 to disengage from the upper roller 952, and the take-up cylinder 961 drives the slide rail 962 to open the horn unit 963, completing the release of the spring wire after the ring is completed. The take-up mechanism 96 resets, and the spring wire falls onto the transmission device 98, completing the production of the spring wire.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
