Description

Technical Field

[0001] The present invention relates to the technical field of trigger torsion spring assembly machinery and equipment, and in particular to a full-automatic trigger spring loading device. Background Art

[0002] A lobster clasp is a kind of ornament, so named because its shape resembles a coiled lobster. Lobster clasps are very common in life, with a wide range of uses, various shapes and types. Generally, the production materials are various metals, and the colors include silver, gold, black, etc. Various colors can be combined with other accessories in different ways.

[0003] A lobster clasp is generally assembled from three components, namely a housing, a trigger and a torsion spring. Among them, the assembly between the trigger and the torsion spring is the most critical and complicated. At present, many processing factories still adopt the manual assembly method, but the manual assembly has low work efficiency and high labor cost. In order to improve work efficiency, there is an automatic assembly machine between the trigger and the torsion spring on the market at present, which is also called a trigger spring loading device. The torsion spring in the trigger spring loading device on the market is a finished product that has been processed by a spring machine. Its assembly method is only to vibrate and press the torsion spring into the trigger, and the triggers are arranged side by side vertically. Each time of pressing requires waiting until all the triggers are arranged. The above-mentioned trigger spring loading device is the mainstream device for assembling the trigger and the torsion spring on the market at present, but it has many defects as follows: First, it cannot ensure that the torsion spring is accurately installed in the trigger in the assembled finished product, and the defective rate is high; Second, the work efficiency is low. During the assembly process, the torsion spring needs to be placed in a suitable position first, and in order to adapt to the spring machine, the triggers are also arranged vertically, and the number of assembled finished products of the trigger and the torsion spring produced per unit time is not high; Third, during the operation of the machine, once a failure occurs, such as the trigger is not clamped, or the torsion spring is not correctly placed into the trigger and the torsion spring falls off, the failure rate of the machine is high, and it cannot be checked and repaired in time, which greatly reduces the operation experience; Fourth, the torsion spring is a finished product produced by a spring machine and needs to be additionally connected to the trigger spring loading device, and the operation is troublesome. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes a full-automatic trigger spring loading device.

[0005] The technical solution adopted by the present invention is: a full-automatic trigger spring loading device, including a frame, having a three-dimensional frame body as the support and installation body of the device;

[0006] A divider, including a divider main body and a dividing disk arranged at the upper end of the divider main body. The divider main body is used to drive the dividing disk to perform intermittent rotational motion. The dividing disk is located above the frame and is horizontally placed;

[0007] Loading die base, there are at least five of the loading die bases, and they are evenly spaced along the rotation direction of the dividing disk. A trigger feeding position is provided on the loading die base, and the trigger feeding position is used to place the trigger, and the trigger is placed horizontally;

[0008] Trigger feeding mechanism, used to intermittently convey the trigger to the trigger feeding position;

[0009] Support assembly, used to support at least four fixed workstations above the dividing disk. When the dividing disk stops rotating, at least four fixed workstations are respectively located above the loading die base. The four fixed workstations are in sequence the material leakage detection workstation, the trigger detection workstation, the spring pressing workstation, and the torsion spring detection workstation along the rotation direction of the dividing disk. And, except for the spring pressing workstation, a spring pressing structure is provided on all fixed workstations. Among them, the material leakage detection workstation is located at the trigger discharging end of the trigger feeding mechanism, and is used to detect whether the trigger leaks successfully from the end of the trigger feeding mechanism. The trigger detection workstation is used to detect whether there is a trigger placed on the trigger feeding position. The torsion spring detection workstation is used to detect whether the torsion spring on the trigger is installed in place;

[0010] Driving mechanism, used to drive the support assembly to perform intermittent up and down displacement, and drive the dividing head main body to work;

[0011] Spring wire feeding mechanism, used to convey spring wire to the lower part of the spring pressing workstation;

[0012] Spring loading mechanism, used to form the spring wire conveyed to the lower part of the spring pressing workstation into a torsion spring, and install the formed torsion spring on the trigger located on the trigger feeding position to form a finished product. The spring pressing workstation is used to cooperate with pressing the torsion spring during the spring loading process of the spring loading mechanism to position the torsion spring;

[0013] Unloading mechanism, used to separately unload the finished products passing through the torsion spring detection workstation and the defective products not passing through the torsion spring detection workstation. An auxiliary unloading structure is provided on the loading die base, and the auxiliary unloading structure is used to cooperate with the unloading mechanism to unload the finished products or the defective products;

[0014] Central control mechanism, directly or indirectly connected to the dividing head, the driving mechanism, the trigger feeding mechanism, the spring wire feeding mechanism, the spring loading mechanism, and the unloading mechanism respectively, and is used to control the operation of the equipment.

[0015] Preferably, the number of the loading die bases is eight, and the number of the fixed workstations is six. The six fixed workstations are respectively a leakage detection workstation, a trigger detection workstation, a compression spring workstation, a torsion spring detection workstation, and two pressing workstations. One of the pressing workstations is located above the blanking mechanism. When the dividing disk stops rotating, the six fixed workstations are respectively located above six of the loading die bases, and there are no fixed workstations above the remaining two loading die bases.

[0016] Through the design of the above technical solution, the design of eight loading die bases can make full use of the space of the dividing disk. Here, the appropriate number of loading die bases is also selected according to the efficiency of installing the torsion spring at the upper spring mechanism to ensure that each process can be seamlessly connected, which can effectively improve the work efficiency. In actual production, reasonable adjustments can be made according to the size of the dividing disk and the working efficiency of the upper spring mechanism.

[0017] Preferably, the trigger feeding mechanism includes a vibrating disk, a conveying track, a material dividing device, a material pushing device, and a trigger pressing-down device. The vibrating disk is used to store triggers and output triggers to the conveying track. The material dividing device is installed on the conveying track and is used to separately feed the triggers continuously conveyed to the conveying track. The trigger pressing-down device is used to assist in pressing down the triggers conveyed to the end of the conveying track and leaking them to the material pushing device. The material pushing device is used to receive the triggers output from the end of the conveying track and push the triggers to the upper end of the trigger placing position of the loading die base.

[0018] Preferably, the conveying track is inclined, and a trigger feeding channel is provided on the upper end surface of the conveying track. An opening is provided on the trigger feeding channel corresponding to the position of the material distributing device. The material distributing device includes two material distributing cylinders arranged oppositely up and down, and an upper material distributing piece and a lower material distributing piece respectively installed on the two material distributing cylinders. One end of the upper material distributing piece is provided with an upper inserting piece, and one end of the lower material distributing piece is provided with a lower inserting piece. The upper inserting piece and the lower inserting piece are respectively driven by the material distributing cylinders and are inserted into the opening in a staggered manner. A receiving plate is provided at the conveying end of the conveying track. The receiving plate is provided with a first material leakage hole. The trigger pressing device is located above the receiving plate and includes a pressing cylinder, a connecting block and a pressing piece. A second cylinder shaft is provided on the pressing cylinder. The connecting block is installed at the end of the second cylinder shaft away from the pressing cylinder. The pressing piece is connected to the connecting block and is disposed directly above the upper end of the first material leakage hole. The material pushing device includes a material pushing cylinder, a first sliding seat, a sliding block and a material pushing plate. A first cylinder shaft is provided on the material pushing cylinder. The sliding block is connected to the end of the first cylinder shaft away from the material pushing cylinder. A sliding groove is provided on the first sliding seat. The sliding block is slidably connected to the sliding groove in a matching manner. The material pushing plate is connected above the first sliding seat and is provided with a second material leakage hole. The shapes of the first material leakage hole and the second material leakage hole are both the same as that of the trigger. When the material pushing cylinder does not push the sliding block to displace, the second material leakage hole is disposed directly below the first material leakage hole.

[0019] Through the design of the above technical solution, since the conveying track is in an inclined state, the triggers output from the vibrating disk and entering the trigger feeding channel will continuously slide downward due to the action of gravity until they are conveyed to the position where the trigger pressing device is located. The two material distributing cylinders respectively drive the upper inserting piece on the upper material distributing piece and the lower inserting piece on the lower material distributing piece to be inserted into the opening on the trigger feeding channel. At this time, the triggers will be limited between the upper inserting piece and the lower inserting piece, so that the feeding interval time of the triggers can be controlled and the subsequent operation steps will not be disrupted. When the triggers are conveyed into the first material leakage hole on the receiving plate, the pressing cylinder in the trigger pressing device drives the second cylinder shaft to displace and drives the pressing piece to press down into the first material leakage hole, leaking the triggers located in the first material leakage hole into the second material leakage hole on the material pushing plate. When the triggers are located in the second material leakage hole, the material pushing cylinder drives the sliding block to slide on the first sliding seat. The sliding of the sliding block will drive the material pushing plate fixed at the upper end of the sliding block to displace. The material pushing plate will be pushed to displace until the second material leakage hole corresponds to the trigger feeding position on the feeding die base. At this time, the driving mechanism drives the supporting component to press down, and the triggers are completely pressed down from the second material leakage hole to the trigger feeding position through the compression spring structure. It should be noted that the compression spring structure provides the downward pressure through the deformation of the spring.

[0020] Preferably, the upper spring mechanism is installed on the frame and includes a top spring device and a wire cutting device. The top spring device includes a first driving component, a top wire knife, and a top spring component connected to the same end of the first driving component. The wire cutting device includes a second driving component and a cutting knife connected to one end of the second driving component. A top wire opening is provided on the top wire knife. The first driving component is used to drive the top wire knife and the top spring component to approach or move away from the loading die base located below the spring pressing station together. The second driving component is used to drive the cutting knife to approach or move away from the loading die base located below the spring pressing station.

[0021] Preferably, the first driving component includes a third motor, a second sliding seat, and a first pushing auxiliary component. The third motor is used to drive the first pushing auxiliary component to slide back and forth on the second sliding seat. The top spring component includes a support, a driving compression torsion spring, and a compression spring piece. Among them, the support is installed at one end of the first pushing auxiliary component close to the spring pressing station. An insertion opening is provided on the support along the longitudinal direction. The compression spring piece is L-shaped, and one end of the compression spring piece passes through the insertion opening. The longitudinal length of the insertion opening is greater than the radial width of the compression spring piece. A clamping spring opening is provided at one end of the compression spring piece above the insertion opening. An arc-shaped transition convex top position is integrally provided on the lower side of one end of the compression spring piece below the insertion opening. The driving compression torsion spring is fixedly installed on the support, and one end of the driving compression torsion spring is clamped in the clamping spring opening. The driving compression torsion spring is used to drive one end of the compression spring piece to abut against the front position of the insertion opening and press down the convex top position. The second driving component includes a fourth motor, a third sliding seat, and a second pushing auxiliary component. The fourth motor is used to drive the second pushing auxiliary component to slide back and forth on the third sliding seat. The cutting knife is installed at one end of the second pushing auxiliary component close to the spring pressing station.

[0022] For easy understanding, the operation process of the upper spring mechanism is briefly described below:

[0023] S1. The spring wire conveying mechanism conveys the spring wire to the lower part of the spring pressing station. At this time, the spring wire is located above the loading die base.

[0024] S2. The first driving component drives the top wire knife to move to the lower part of the spring pressing station and twists the spring wire into a torsion spring through the top wire opening. At this time, the torsion spring is located at the trigger feeding position.

[0025] S3. After the torsion spring is formed, the first driving component drives the top wire knife to return to its original position.

[0026] S4. The driving mechanism drives the support component to move downward, so that the spring pressing station located on the support component moves downward and abuts against the torsion spring formed in S3.

[0027] S5. The second driving component drives the cutting knife to displace and approach the loading die base located below the compression spring station until the cutting knife cuts off the spring wire connected to the torsion spring.

[0028] S6. The second driving component drives the cutting knife to return to its original position. And at the same time when the second driving component just starts to drive the cutting knife to return to its original position, the first driving component drives the top spring component to displace and approach the loading die base located below the compression spring station.

[0029] S7. When the lower convex top position contacts the upper end face of the loading die base, the upper end face of the loading die base supports the lower convex top position to displace upward, and drives one end of the compression spring piece to abut against the rear position of the insertion port. The lower convex top position continues to displace to the trigger discharging position under the drive of the first driving component. At this time, the lower convex top position is driven by the driving and pressing torsion spring to displace downward, and presses the torsion spring into the inside of the trigger discharging position.

[0030] S8. When the lower convex top position in S7 presses the torsion spring into the inside of the trigger discharging position, the cutting knife has returned to its original position. Then the first driving component drives the top spring component to return to its original position, and the driving mechanism drives the supporting component to displace upward, and it is completed.

[0031] Through the above technical solution design, when the dividing disk stops rotating, one of the loading die bases will be located below the compression spring station, and a trigger will be provided in this loading die base. By repeating the operation steps such as S1 - S8 above, it can be realized that the spring wire transported to below the compression spring station is formed into a torsion spring, and the formed torsion spring is installed on the trigger located at the trigger discharging position to form a finished product. Since the whole process is mechanized operation, and the interval time between the operation steps of using the cutting knife to cut off the spring wire and pressing the torsion spring into the trigger is extremely short, it is basically synchronous, and the working efficiency is extremely high. It should be noted here that due to the deformation tendency of the driving and pressing torsion spring itself, the lower convex top position located at the lower end of the compression spring piece is in a downward pressing state. At this time, the horizontal plane where the lowermost end of the lower convex top position is located is lower than the upper end face of the loading die base. Therefore, when the first driving component drives the top spring component to displace and approach the loading die base located below the compression spring station, since the lower convex top position abuts against the upper end face of the loading die base through the arc transition of its outer contour, there will be a relative acting force between the lower convex top position and the loading die base at this time. Once the lower convex top position displaces to the trigger discharging position, the driving and pressing torsion spring immediately drives and presses the compression spring piece, so that the lower convex top position presses the formed torsion spring into the trigger discharging position.

[0032] Preferably, the driving mechanism includes a fifth motor, a transmission main shaft, a grooved pulley, and a column. One end of the fifth motor is provided with a driving sprocket, and a driven sprocket is fixedly arranged on the transmission main shaft. The driving sprocket and the driven sprocket are connected by a chain. There are two grooved pulleys, which are symmetrically and fixedly installed on the front and rear sides of the transmission main shaft. One end of the column is connected to the grooved pulley through a roller. The end of the column away from the grooved pulley extends above the frame and is fixedly connected to the support assembly. One end of the transmission main shaft is provided with a handwheel. At least one main shaft fixing seat is sleeved on the transmission main shaft. The main shaft fixing seat is connected to the frame through a fixing rod. A second driving gear is fixedly arranged on the transmission main shaft. A first driven gear is arranged on the dividing head body. The second driving gear and the first driven gear are meshed with each other.

[0033] Through the design of the above technical solution, when the equipment starts to work, the fifth motor drives the driving sprocket to rotate. Since the driving sprocket and the driven sprocket are connected by a chain, the rotation of the driving sprocket will drive the driven sprocket to rotate. Since the driven sprocket is fixed on the transmission main shaft, the rotation of the driven sprocket will drive the transmission main shaft to rotate. The rotation of the transmission main shaft will drive the grooved pulley and the second driving gear located on the transmission main shaft to rotate. Among them, since the second driving gear and the first driven gear are meshed, and the first driven gear is installed on the dividing head body, the dividing head body can be driven to work, and the dividing plate connected to the dividing head body can be driven to rotate. In addition, since one end of the column connected to the support assembly is connected to the grooved pulley through a roller, the rotation of the grooved pulley can control the up and down displacement of the column, and then the support assembly generates up and down displacement. It is equivalent to the work of the fifth motor, providing power for the up and down displacement of the support assembly and the rotation of the dividing plate.

[0034] Preferably, the support assembly includes a main support rod, and a first cross brace, a second cross brace, a third cross brace, and a fourth cross brace that are fixedly installed on the main support rod in sequence along the extending direction of the main support rod. Among them, the material leakage detection station is arranged on the first cross brace, the trigger detection station is arranged at one end of the main support rod close to the first cross brace, the compression spring station is arranged on the second cross brace, the torsion spring detection station is arranged on the fourth cross brace, and a pressing station is installed on the third cross brace. The pressing station is correspondingly arranged above the blanking mechanism.

[0035] It should be noted that when the material leakage detection station detects that the trigger in the second material leakage hole does not leak material into the trigger feeding position, the equipment will automatically alarm and stop running. At this time, the equipment needs to be manually debugged, and the jammed trigger should be taken out or placed on the trigger placement position. After ensuring that there is no problem, the equipment can be restarted. When the trigger detection station detects that the trigger is not pressed and combined into the trigger feeding position by the compression spring structure, the subsequent steps of this loading die base are cancelled, and the process steps of other loading die bases are not affected. When the torsion spring detection station detects that the torsion spring is not pressed and combined into the trigger by the compression spring station, the subsequent steps of this loading die base are cancelled, and the process steps of other loading die bases are not affected. When this loading die base rotates to the unloading mechanism, it is unloaded into the waste storage box through the unloading mechanism.

[0036] More preferably, the loading die base is horizontally arranged and includes a die base body, a baffle, a sliding part, an upper cover plate, a return spring, a bearing seat and a bearing. Here, the baffle, the sliding part, the return spring, the bearing seat and the bearing are the auxiliary unloading structures. Among them, the upper cover plate covers the upper end of the die base body, and the trigger feeding position is arranged on the upper cover plate. The lower end face of the die base body is provided with a discharge port, and the discharge port is directly below the trigger feeding position. The sliding part is slidably connected in the die base body, and the upper end face of the sliding part is in direct contact with the upper cover plate. The lower end of the trigger in the trigger feeding position abuts against the sliding part. The baffle is installed on one side of the sliding part close to the discharge port, the bearing seat is installed on the side of the sliding part away from the baffle, the bearing is installed above the bearing seat. The sliding part and the baffle are integrally formed. The return spring is installed between the baffle and the die base body. The unloading mechanism includes a guiding piece, a material distribution box, a driving cylinder, a waste storage box, an unloading pipeline and a rotating auxiliary part. The guiding piece is fixedly installed above the frame, and the guiding piece is provided with an outward convex transition position. When the dividing disk drives the loading die base to rotate above the unloading mechanism, the guiding piece drives the bearing to move outward through the outward convex transition position and drives the sliding part to move outward. At this time, the trigger feeding position and the discharge port are directly communicated. A number of unloading relief openings are evenly spaced and annularly arranged on the edge of the dividing disk. When the dividing disk stops rotating, the unloading relief opening is directly below the discharge port. The material distribution box is directly below the discharge port, the rotating auxiliary part is located on one side of the material distribution box, and the driving cylinder drives the material distribution box to rotate through the rotating auxiliary part and communicates with the waste storage box. When the material distribution box does not rotate, the material distribution box is communicated with the unloading pipeline.

[0037] Through the above technical solution design, when the loading die seat rotates to the unloading mechanism through the rotation of the dividing plate, the bearing on the loading die seat will contact the convex transition position of the guide plate. Since the convex transition position is tangent to the bearing, the bearing will be pushed outward through the convex transition position at this time, thereby causing the bearing seat connected to the lower end of the bearing and the sliding member connected to the bearing seat to slide outward. Since the sliding member and the baffle are integrally formed, the baffle will also slide outward, thereby compressing the reset spring connected between the baffle and the die seat body. At this time, the trigger discharge position and the discharge port are directly connected, and the discharge port and the unloading clearance port are connected. Therefore, the assembled product of the trigger and torsion spring located in the trigger discharge position can be smoothly dropped into the distribution box and unloaded through the unloading pipeline. It should be noted that when it is detected that the trigger located in the trigger discharge position is waste, the driving cylinder drives the distribution box to rotate through the rotating auxiliary part and connects to the waste storage box, and then transports the waste in the distribution box to the waste storage box to achieve separate unloading. The trigger in the waste storage box without a torsion spring installed or the torsion spring is not installed in place can be processed and placed back in the vibration plate.

[0038] Compared with the prior art, the present invention has the following beneficial effects: the present invention overturns the traditional trigger torsion spring assembly method of the trigger spring loading device, adjusts the assembly process of the trigger and the torsion spring to the horizontal direction, combines the torsion spring forming and the automatic assembly into one device, and has higher working efficiency. By designing multiple inspection processes, the defective rate of the final product is effectively reduced. The whole machine has a high degree of operation automation, a long service life, and is easy to debug, meeting the needs of modern production. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

The spring pressing workstation 531 is used to cooperate with pressing the torsion spring b during the spring loading process of the spring loading mechanism 700 to position the torsion spring b;

[0082] The blanking mechanism 900 is used to separately blank the finished products that pass through the torsion spring detection workstation 551 and the defective products that do not pass through the torsion spring detection workstation 551. An auxiliary blanking structure is provided on the loading die base 400, and the auxiliary blanking structure is used to cooperate with the blanking mechanism 900 to blank the finished products or defective products;

[0083] The central control mechanism 1000 is directly or indirectly connected to the dividing head 300, the driving mechanism 800, the trigger feeding mechanism 200, the spring wire conveying mechanism 600, the spring loading mechanism 700, and the blanking mechanism 900 respectively, and is used to control the operation of the equipment. Here, the central control mechanism 1000 is generally a PLC.

[0084] In this embodiment, please refer to Figure 5, for convenient output, the spring wire conveying mechanism 600 is adjusted to a spring machine placed horizontally. The spring wire conveying mechanism 600 includes a wire outlet device 610, a straightener 620, a wire clamping device 630, a wire feeding device 640, and a wire running device 650. Among them, the wire outlet device 610 is a wire storage disc 611, and the wire storage disc 611 is connected with a first motor 612. The first motor 612 is used to drive the wire storage disc 611 to output spring wire. After the output spring wire passes through the straightener 620, it is clamped by the wire clamping device 630 and conveyed to the wire running device 650. Among them, the wire feeding device 640 is installed on the wire running device 650 and includes a second motor 641, a first driving gear 642, a second driven gear 643, a third driven gear 644, and a wire feeding roller 645. The second motor 641 drives the first driving gear 642 to rotate. The first driving gear 642 meshes with the second driven gear 643, and the second driven gear 643 meshes with the third driven gear 644. There are two wire feeding rollers 645, which are respectively connected above the second driven gear 643 and the third driven gear 644. Therefore, the rotation of the first driving gear 642 can drive the two wire feeding rollers 645 to rotate, realizing wire feeding. The wire running device 650 is used to convey the processed spring wire to the lower part of the spring pressing station 531.

[0085] Specifically, please refer to Figure 19 and Figure 20 , the number of the loading die bases 400 is eight, and the number of the fixed stations is six. The six fixed stations are respectively a blank leakage detection station 521, a trigger detection station 511, a spring pressing station 531, a torsion spring detection station 551, and two pressing stations. One of the pressing stations is located above the blanking mechanism 900. When the dividing disc stops rotating, the six fixed stations are respectively located above six of the loading die bases 400, and there are no fixed stations arranged above the remaining two loading die bases 400.

[0086] In this embodiment, the design of the eight loading die bases 400 can make full use of the space of the dividing disc 320. Here, the appropriate number of loading die bases 400 is selected according to the efficiency of installing the torsion spring b at the spring loading mechanism 700 to ensure that each process can be seamlessly connected, effectively improving the working efficiency. In actual production, reasonable adjustment can be made according to the size of the dividing disc 320 and the working efficiency of the spring loading mechanism 700.

[0087] Then, please refer to Figures 10 - 16, the trigger feeding mechanism 200 includes a vibrating bowl 210, a conveying track 220, a material separating device 230, a pushing device 240, and a trigger pressing device 250. The vibrating bowl 210 is used to store the trigger a and output the trigger a to the conveying track 220. The material separating device 230 is installed on the conveying track 220 and is used to separately feed the triggers a continuously conveyed to the conveying track 220. The trigger pressing device 250 is used to assist in pressing down the trigger a conveyed to the end of the conveying track 220 and leaking the material to the pushing device 240. The pushing device 240 is used to receive the trigger a output from the end of the conveying track 220 and push the trigger a to the upper end of the trigger feeding position 441 of the feeding die base 400.

[0088] As a preferred implementation manner of this embodiment, the conveying track 220 is inclined, and a trigger feeding channel 221 is provided on the upper end surface of the conveying track 220. An opening 222 is provided at a position on the trigger feeding channel 221 corresponding to the material separating device 230. The material separating device 230 includes two material separating cylinders 231 arranged oppositely up and down, and an upper material separating plate 232 and a lower material separating plate 233 respectively installed on the two material separating cylinders 231. One end of the upper material separating plate 232 is provided with an upper inserting piece 2321, and one end of the lower material separating plate 233 is provided with a lower inserting piece 2331. The upper inserting piece 2321 and the lower inserting piece 2331 are respectively driven by the material separating cylinder 231 and are inserted into the opening 222 in a staggered manner. A receiving plate 223 is provided at the conveying end of the conveying track 220, and a first leakage hole 2231 is provided on the receiving plate 223. The trigger pressing device 250 is located above the receiving plate 2231 and includes a pressing cylinder 251, a connecting block 252, and a pressing member 2521. A second cylinder shaft 2511 is provided on the pressing cylinder 251. The connecting block 252 is installed at the end of the second cylinder shaft 2511 away from the pressing cylinder 251. The pressing member 2521 is connected to the connecting block 252, and the pressing member 2521 is disposed directly opposite to the upper end of the first leakage hole 2231. The pushing device 240 includes a pushing cylinder 241, a first sliding seat 243, a slider 244, and a pushing plate 245. A first cylinder shaft 2411 is provided on the pushing cylinder 241. The slider 244 is connected to the end of the first cylinder shaft 2411 away from the pushing cylinder 241. A sliding groove 2431 is provided on the first sliding seat 243, and the slider 244 is slidably engaged in the sliding groove 2431. The pushing plate 245 is connected above the first sliding seat 243, and a second leakage hole 2451 is provided on the pushing plate 245. The shapes of the first leakage hole 2231 and the second leakage hole 2451 are both the same as that of the trigger a, and when the pushing cylinder 241 does not push the slider 244 to displace, the second leakage hole 3451 is disposed directly below the first leakage hole 2231.

[0089] In this embodiment, since the conveying track is in an inclined state, the trigger a output by the vibrating disk 210 and entering the trigger feeding channel 221 will continuously slide downward due to the action of gravity until it is conveyed to the position where the trigger pressing device 250 is located. The two feeding cylinders 231 respectively drive the upper inserting piece 2321 on the upper feeding piece 232 and the lower inserting piece 2331 on the lower feeding piece 233 to be inserted into the opening 222 on the trigger feeding channel 221. At this time, the trigger a will be limited between the upper inserting piece 2321 and the lower inserting piece 2331, so that the feeding interval time of the trigger a can be controlled and the subsequent operation steps will not be disrupted. When the trigger a is conveyed into the first leakage hole 2231 on the receiving plate 223, the pressing cylinder 251 in the trigger pressing device 250 drives the second cylinder shaft 2511 to displace, and drives the pressing piece 2521 to press down into the first leakage hole 2231, so that the trigger a located in the first leakage hole 2231 leaks into the second leakage hole 2451 on the pushing plate 245. When the trigger a is located in the second leakage hole 2451, the pushing cylinder 241 drives the slider 244 to slide on the first sliding seat 243. The sliding of the slider 244 will drive the pushing plate 245 fixed at the upper end of the slider 244 to displace. The pushing plate 245 will be pushed to displace until it corresponds to the trigger placing position 441 on the second leakage hole 2451 and the feeding die base 400. At this time, the driving mechanism 800 drives the supporting assembly 500 to press down, and the trigger a is completely pressed down from the second leakage hole 2451 to the trigger placing position 441 through the spring pressing structure. It should be noted that the spring pressing structure provides the pressing force through the deformation of the spring.

[0090] As another preferred implementation manner of this embodiment, the upper spring mechanism 700 is installed on the frame 100 and includes a top spring device 710 and a wire cutting device 720. The top spring device 710 includes a first driving component and a top wire knife 714 and a top spring assembly connected to the same end of the first driving component. The wire cutting device 720 includes a second driving component and a cutting knife 723 connected to one end of the second driving component. A top wire opening 7141 is provided on the top wire knife 714. The first driving component is used to drive the top wire knife 714 and the top spring assembly to approach or move away from the feeding die base 400 located below the spring pressing station 531 together. The second driving component is used to drive the cutting knife 723 to approach or move away from the feeding die base 400 located below the spring pressing station 531.

[0091] Specifically, please refer to Figure 3 and Figure 4, the first driving component includes a third motor 717, a second sliding seat 711 and a first pushing auxiliary component 712. The third motor 717 is used to drive the first pushing auxiliary component 712 to slide back and forth on the second sliding seat 711. The top spring assembly includes a support 715, a driving and pressing torsion spring 716 and a spring pressing piece 713. Among them, the support 715 is installed at one end of the first pushing auxiliary component 712 close to the spring pressing station 531. An insertion port 7151 is provided on the support 715 along the long direction. The spring pressing piece 713 is L-shaped, and one end of the spring pressing piece 713 passes through the insertion port 7151. The length of the insertion port 7151 in the long direction is greater than the radial width of the spring pressing piece 713. A snap spring port 7133 is provided at one end of the spring pressing piece 713 above the insertion port 7151. An arc-shaped transition lower convex top position 7131 is integrally provided on the lower side of one end of the spring pressing piece 713 below the insertion port 7151. The driving and pressing torsion spring 716 is fixedly installed on the support 715, and one end of the driving and pressing torsion spring 716 is clamped in the snap spring port 7133. The driving and pressing torsion spring 716 is used to drive one end of the spring pressing piece 713 to abut against a position closer to the front of the insertion port 7151 and press down the lower convex top position 7131. The second driving component includes a fourth motor 724, a third sliding seat 721 and a second pushing auxiliary component 722. The fourth motor 724 is used to drive the second pushing auxiliary component 722 to slide back and forth on the third sliding seat 721. The cutting knife 723 is installed at one end of the second pushing auxiliary component 722 close to the spring pressing station 531.

[0092] For the convenience of understanding, the operation process of the spring loading mechanism is briefly described below:

[0093] S1. The spring wire conveying mechanism 600 conveys the spring wire to the lower part of the spring pressing station 531. At this time, the spring wire is located above the feeding die base 400;

[0094] S2. The first driving component drives the top wire cutter 714 to displace to the lower part of the spring pressing station 531 and twist the spring wire into a torsion spring b through the top wire port 7141. At this time, the torsion spring b is located at the trigger feeding position 441;

[0095] S3. After the torsion spring b is formed, the first driving component drives the top wire cutter 814 to return to its original position;

[0096] S4. The driving mechanism 800 drives the support component 500 to displace downward, so that the spring pressing station 531 located on the support component 500 displaces downward and abuts against the torsion spring b formed in S3;

[0097] S5. The second driving component drives the cutting knife 723 to displace and approach the feeding die base 400 located below the spring pressing station 531 until the cutting knife 723 cuts off the spring wire connected to the torsion spring b;

[0098] S6. The second driving component drives the cutting knife 723 to return to its original position. And at the same time when the second driving component starts to drive the cutting knife 723 to prepare to return to its original position, the first driving component drives the top spring component to displace and approach the feeding die base 400 located below the spring pressing station 531.

[0099] S7. When the lower convex top position 7131 contacts the upper end face of the feeding die base 400, the upper end face of the feeding die base 400 supports the lower convex top position 7131 to displace upward, and drives one end of the spring pressing piece 713 to abut against the rear position of the insertion interface 7151. The lower convex top position 7131 continues to displace to the trigger feeding position 441 under the drive of the first driving component. At this time, the lower convex top position 7131 is driven by the driving and pressing torsion spring 716 to displace downward, and presses the torsion spring b into the inside of the trigger feeding position 441.

[0100] S8. When the lower convex top position 7131 in S7 presses the torsion spring b into the inside of the trigger feeding position 441, the cutting knife 723 has returned to its original position. Then the first driving component drives the top spring component to return to its original position, and the driving mechanism 800 drives the supporting component 500 to displace upward, and it is completed.

[0101] In this embodiment, when the dividing disk 320 stops rotating, one of the feeding die bases 400 will be located below the spring pressing station 531, and a trigger a will be provided in this feeding die base 400. By repeating the operation procedures in S1 - S8 as above, it can realize forming the spring wire conveyed to below the spring pressing station 531 into a torsion spring b, and installing the formed torsion spring b on the trigger a located at the trigger feeding position 441 to form a finished product. Since the whole process is mechanized operation, and the interval time between the operation procedures of using the cutting knife 723 to cut the spring wire and pressing the torsion spring b into the trigger a is extremely short, and it is basically synchronous, the working efficiency is extremely high. It should be noted here that due to the deformation trend of the driving and pressing torsion spring 716 itself, the lower convex top position 7131 located at the lower end of the spring pressing piece 713 is in a downward pressing state. At this time, the horizontal plane where the lowest end of the lower convex top position 7131 is located is lower than the upper end face of the feeding die base 400. Therefore, when the first driving component drives the top spring component to displace and approach the feeding die base 400 located below the spring pressing station 531, since the lower convex top position 7131 abuts against the upper end face of the feeding die base 400 through the arc transition of its outer contour, there will be a relative acting force between the lower convex top position 7131 and the feeding die base 400 at this time. Once the lower convex top position 7131 displaces to the trigger feeding position 441, the driving and pressing torsion spring 716 immediately drives and presses the spring pressing piece 713, so that the lower convex top position 7131 presses the already formed torsion spring b into the trigger feeding position 441.

[0102] Next, please refer to Figure 23, the driving mechanism 800 includes a fifth motor 810, a transmission main shaft 830, a grooved pulley 860, and a column 870. One end of the fifth motor 810 is provided with a driving sprocket 820, and a driven sprocket 840 is fixedly provided on the transmission main shaft 830. The driving sprocket 820 and the driven sprocket 540 are connected by a chain. There are two grooved pulleys 860, which are symmetrically and fixedly installed on the front and rear sides of the transmission main shaft 830. One end of the column 870 is connected to the grooved pulley 860 through a roller. The end of the column 870 away from the grooved pulley 860 extends above the frame 100 and is fixedly connected to the support assembly 500. One end of the transmission main shaft 830 is provided with a handwheel 850. At least one main shaft fixing seat 890 is sleeved on the transmission main shaft 830. The main shaft fixing seat 890 is connected to the frame 100 through a fixing rod 891. A second driving gear 880 is fixedly provided on the transmission main shaft 830, and a first driven gear 311 is provided on the dividing head main body 310. The second driving gear 880 and the first driven gear 311 are meshed with each other.

[0103] In this embodiment, when the device starts to work, the fifth motor 810 drives the driving sprocket 820 to rotate. Since the driving sprocket 820 and the driven sprocket 840 are connected by a chain, the rotation of the driving chain 820 will drive the driven sprocket 840 to rotate. Since the driven sprocket 840 is fixed on the transmission main shaft 830, the rotation of the driven sprocket 840 will drive the transmission main shaft 830 to rotate. The rotation of the transmission main shaft 830 will drive the grooved pulley 860 and the second driving gear 880 located on the transmission main shaft 830 to rotate. Among them, since the second driving gear 880 and the first driven gear 311 are meshed, and the first driven gear 311 is installed on the dividing head main body 310, the dividing head main body 310 can be driven to work, and the dividing disk 320 connected to the dividing head main body 310 can be driven to rotate. In addition, since one end of the column 870 connected to the support assembly 500 is connected to the grooved pulley 860 through a roller, the up and down displacement of the column 870 can be controlled by the rotation of the grooved pulley 860, so that the support assembly 500 generates up and down displacement. It is equivalent to the work of the fifth motor 810, providing power for the up and down displacement of the support assembly 500 and the rotation of the dividing disk 320.

[0104] Next, please refer to Figures 19 - 20, the support component 500 includes a main support rod 510, and a first cross bar 520, a second cross bar 530, a third cross bar 540, and a fourth cross bar 550 that are sequentially and fixedly installed on the main support rod 510 along the extending direction of the main support rod 510. Among them, a material leakage detection station 521 is arranged on the first cross bar 520, a trigger detection station 511 is arranged at one end of the main support rod 510 close to the first cross bar 520, a compression spring station 531 is arranged on the second cross bar 530, a torsion spring detection station 551 is arranged on the fourth cross bar 550, and a pressing station is installed on the third cross bar 540, and the pressing station is correspondingly arranged above the feeding mechanism 900.

[0105] Please refer to Figure 29 , the compression spring station 531 includes a socket 5311, a sliding rod 5312, a limiting piece 5313, a spring 5314, and a pressing block 5315. Among them, the socket 5311 is installed on the second cross bar 530, the sliding rod 5312 is slidably connected in the socket 5311, the pressing block 5315 is arranged at the lower end of the sliding rod 5312, and the spring 5314 is installed between the pressing block 5315 and the socket 5311. The limiting piece 5313 is arranged at the upper end of the sliding rod 5312. When the second cross bar 530 moves downward and drives the socket 5311 to move downward, the pressing block 5315 will contact the torsion spring b. When the socket 5311 continues to press down, at this time the spring 5314 will be compressed, and the position of the sliding rod 5312 remains unchanged. The socket 5311 moves downward relative to the sliding rod 5312, and the limiting piece 5313 is used as a limit during the reset process of the socket 5311 to ensure that the socket 5311 and the sliding rod 5312 will not separate.

[0106] It should be noted that when the material leakage detection station 521 detects that the trigger a in the second material leakage hole 2451 does not leak material into the trigger feeding position 441, the equipment will automatically alarm and stop running. At this time, the equipment needs to be manually debugged, and the jammed trigger a needs to be taken out or placed on the trigger placement position 441. After ensuring that there is no problem, the equipment is restarted. When the trigger detection station 511 detects that the trigger a is not pressed and combined into the trigger feeding position 441 by the compression spring structure, the subsequent steps of the upper die base 400 are cancelled, and the process steps of other upper die bases 400 are not affected. When the torsion spring detection station 551 detects that the torsion spring b is not pressed and combined into the trigger a by the compression spring station 531, the subsequent steps of the upper die base 400 are cancelled, and the process steps of other upper die bases 400 are not affected. When the upper die base 400 rotates to the feeding mechanism 900, it is fed into the waste storage box 940 through the feeding mechanism 900.

[0107] More specifically, please refer to Figures 25 - 28, the loading die base 400 is horizontally arranged and includes a die base body 410, a baffle 420, a sliding member 430, an upper cover plate 440, a return spring 470, a bearing seat 450, and a bearing 460. Here, the baffle 420, the sliding member 430, the return spring 470, the bearing seat 450, and the bearing 460 are the auxiliary blanking structures. Among them, the upper cover plate 440 is placed on the upper end of the die base body 410, and a trigger feeding position 441 is provided on the upper cover plate 440. An outlet is provided on the lower end surface of the die base body 410, and the outlet is directly below the trigger feeding position 441. The sliding member 430 is slidably connected in the die base body 410, and the upper end surface of the sliding member 430 is in direct contact with the upper cover plate 440. The lower end of the trigger a in the trigger feeding position 441 abuts against the sliding member 430. The baffle 420 is installed on one side of the sliding member 430 close to the outlet. The bearing seat 450 is installed on the side of the sliding member 430 away from the baffle 420. The bearing 460 is installed above the bearing seat 450. The sliding member 430 and the baffle 420 are integrally formed. The return spring 470 is installed between the baffle 420 and the die base body 410. The blanking mechanism 900 includes a guiding piece 910, a material distribution box 920, a driving cylinder 930, a waste storage box 940, a blanking pipeline 950, and a rotating auxiliary part 960. The guiding piece 910 is fixedly installed above the frame 100, and an outward convex transition position 911 is provided on the guiding piece 910. When the dividing disk 320 drives the loading die base 400 to rotate above the blanking mechanism 900, the guiding piece 910 drives the bearing 460 to move outward through the outward convex transition position 911, and drives the sliding member 430 to move outward. At this time, the trigger feeding position 441 and the outlet are directly communicated. A number of blanking relief openings 321 are evenly spaced in a ring on the edge of the dividing disk 320. When the dividing disk 320 stops rotating, the blanking relief openings 321 are directly below the outlet. The material distribution box 920 is directly below the outlet. The rotating auxiliary part 960 is located on one side of the material distribution box 920. The driving cylinder 930 drives the material distribution box 820 to rotate through the rotating auxiliary part 960 and communicates with the waste storage box 940. When the material distribution box 920 does not rotate, the material distribution box 920 is communicated with the blanking pipeline 950, and the finished product is blanked through the blanking pipeline 950.

[0108] Through the design of the above technical solution, when the loading die base 400 rotates to the unloading mechanism 900 via the rotation of the dividing disk 320, the bearing 460 on the loading die base 400 will contact the convex transition position 911 of the guiding piece 910. Since the convex transition position 911 is tangent to the bearing 460, the bearing 460 will be pushed outwards via the convex transition position 911 at this time. As a result, the bearing seat 450 connected to the lower end of the bearing 460, and the sliding member 430 connected to the bearing seat 450 slide outwards. Since the sliding member 430 and the baffle 420 are integrally formed, the baffle 420 also slides outwards, and thus the return spring 470 connected between the baffle 420 and the die base body 410 is compressed. At this time, the trigger discharging position 441 is directly communicated with the discharging port, and the discharging port is communicated with the unloading relief opening 321. Therefore, the assembled product of the trigger a and the torsion spring b located in the trigger discharging position 441 can smoothly fall into the material distribution box 920 and be discharged through the unloading pipeline 950. It should be noted that when it is detected that the trigger a located in the trigger discharging position 441 at this time is a defective product, the driving cylinder 930 drives the material distribution box 920 to rotate and communicate with the waste storage box 940 through the rotation auxiliary member 960, and then conveys the defective product located in the material distribution box 920 to the waste storage box 940 to achieve separate discharging. The trigger a that does not have the torsion spring b installed or the torsion spring b is not installed in place in the waste storage box 940 can be processed and then placed back into the vibrating disk 210 again.
