[0002] The core components of a wall switch include metal sheets and springs, and their precise assembly directly affects the conduction stability and service life of the switch. However, due to the small size and thin thickness of the metal sheets, and the miniaturization and easy deformation of the springs, manual or traditional automated equipment faces the following problems during the assembly process:

Traditional forks cannot be inserted between the metal sheets to position them, and subsequent transfer cannot be carried out.

[0070] Separation step: The workpiece queue is divided into two groups of workpiece groups by the alternating movement of the fixed block and the sliding block of the separation module. The sliding block is driven by a transverse cylinder to move between the separation position and the coincidence position. When the sliding block is in the separation position, a separation channel for introducing the workpiece queue is formed; when the sliding block moves to the coincidence position, it pushes the corresponding workpiece group to be separated horizontally to one side of the fixed block, and the other workpiece group remains in place.

[0071] Transfer step: The two separated workpiece groups are synchronously transferred to two parallel transfer chutes through the feeding mechanism of the transfer module and move along the transfer chutes to subsequent stations.

[0072] Assembly step: At the assembly stations corresponding to the two transfer chutes, the spring is installed at the preset position of the sheet workpiece.

[0073] Preferably, the separation step includes:

[0074] The sliding block moves to the separation position, and the fixed block and the sliding block are horizontally misaligned to form a separation channel, and the sheet workpiece queue is introduced.

[0075] The sliding block moves from the separation position to the coincidence position, and pushes the corresponding workpiece group to be separated horizontally to one side of the fixed block, and the other workpiece group remains at the original position of the fixed block.

[0076] The stop cylinder drives the stop plate to withdraw from the end of the separation channel, and the feeding mechanism is synchronously inserted into the gap between the first workpiece group and the second workpiece group after separation to complete the separation and positioning of the two groups of workpieces.

[0077] Preferably, the transfer step includes:

[0078] The transfer cylinder drives the transfer plate to move to the first feeding position, and the plugging cylinder drives the fork to extend horizontally, so that the first fork inserts into the gap between the workpiece groups at the separation station, the second fork inserts into the gap between the workpiece groups at the first assembly station, the third fork inserts into the gap between the workpiece groups at the second assembly station, and the fourth fork inserts into the gap between the workpiece groups at the buffer station;

[0080] After the spring assembly module completes the assembly, the plugging cylinder resets the fork, and the transfer cylinder drives the transfer plate to return to the first feeding position.

[0081] The dual-path parallel assembly equipment of the present invention has the following beneficial technical effects:

[0082] 1. The separation module synchronously realizes the separation and grouping of sheet-shaped workpieces through the alternating displacement of the sliding block and the fixed block, and has the characteristics of high production efficiency;

[0083] 2. The two transfer chutes of the transfer module are docked with the output end of the separation module, and the two groups of separated workpieces are directly aligned with the two transfer chutes, without the need for an additional transfer mechanism for extra operations, effectively shortening the length of the equipment;

[0084] 3. There is a gap between each group of workpieces after separation, and the feeding structure can accurately insert into the gap to position the sheet-shaped workpieces;

[0085] 4. Through the mechanical material distribution of the sliding block and the fixed block, due to the simple logic, the cost is lower, and the equipment failure rate is also lower.

[0086] In addition, the separation module of the present invention has the following beneficial effects:

[0087] 1. The fixed block and the sliding block are in a convex shape, so that the horizontal cylinder and the feeding mechanism are arranged in layers. When the feeding mechanism positions the sheet-shaped workpiece, it is located above the horizontal cylinder and does not require additional displacement for avoidance;

[0088] 2. The separation channel serves as a temporary channel when introducing the workpiece queue. When the sliding block moves to the overlapping position, it automatically switches to the first workpiece channel, and at the same time, the separated sheet-shaped workpieces automatically enter the second workpiece channel, which only requires the mechanical movement of the sliding block and does not require sensor or program intervention, with higher working efficiency;

[0089] 3. By cooperating with each other, the inner positioning surface and the outer positioning surface form a closed first workpiece groove and second workpiece groove, which can ensure the limit of the sheet-like part all the time. Even at the separation position, the alternately arranged outer positioning surface and inner positioning surface still form a continuous separation channel to reliably limit the sheet-like workpiece from both sides;

[0090] 4. The fixing block, the sliding block and the positioning part can all be replaced to adapt to sheet-like workpieces of different sizes and shapes. Brief Description of the Drawings

[0142] The following embodiments given in conjunction with the accompanying drawings further illustrate the specific embodiments of the dual - path parallel assembly device of the present invention. The dual - path parallel assembly device of the present invention is not limited to the description of the following embodiments.

[0143] As Figure 1-2 shown, this embodiment provides a spring assembly device, including a dual - path parallel assembly device and two spring assembly modules. The dual - path parallel assembly device is used to convey two paths of sheet - like workpieces A1 in parallel to the corresponding spring assembly modules. The spring assembly modules install the cylindrical spring A2 onto the protrusions on the top of the sheet - like workpieces A1. In this embodiment, the sheet - like workpiece A1 is a metal sheet, and the metal sheet and the spring A2 constitute a part of the conductive system of the wall switch. The on - off of the control circuit is realized by the contact and separation of the metal sheet and the static contact piece, and the spring A2 is used to provide contact pressure for the metal sheet.

[0144] It can be understood that the dual - path parallel assembly device in this embodiment can also convey other sheet - like workpieces A1, not limited to metal sheets, which can be plastic sheets or other materials, and can also be of other shapes. In addition, other assembly devices can be used to assemble parts other than the spring A2 onto the sheet - like workpiece A1, which is not specifically limited here.

[0145] AsFigure 3-7 As shown in Figure 3-7 , the dual-path parallel assembly device of this embodiment includes:

[0146] A feeding module 1 that sorts the sheet-shaped workpieces A1 into a workpiece queue of a predetermined number, such as 8 pieces / group, and outputs them to a separation module 2.

[0147] The separation module 2 includes fixed blocks 21 and sliding blocks 22 arranged alternately along the longitudinal direction. The sliding blocks 22 are driven by a transverse cylinder 23 and move transversely between a separation position and a coincidence position. The longitudinal and transverse directions are two mutually perpendicular directions in the horizontal plane. Figure 3 :

[0148] When the sliding block 22 moves to the separation position Figure 4-5 , the center line of the sliding block 22 is parallel to the center line of the fixed block 21. The sliding block 22 and the fixed block 21 are transversely misaligned to form a plurality of gaps. Through the plurality of gaps, a separation channel B0 is formed. When the workpiece queue is introduced into the separation channel B0, due to the alternating arrangement of the sliding block 22 and the fixed block 21, each sheet-shaped workpiece A1 corresponds to a sliding block 22 or a fixed block 21.

[0149] When the sliding block 22 moves from the separation position to the coincidence position Figure 6-7 , the center line of the sliding block 22 coincides with the center line of the fixed block 21, realizing the longitudinal alignment of the sliding block 22 and the fixed block 21. The sliding block 22 pushes the corresponding sheet-shaped workpiece A1 to move transversely to one side of the fixed block 21, and the fixed block 21 remains in place, and the corresponding sheet-shaped workpiece A1 thereof is maintained in the separation channel B0 on the other side of the fixed block 21.

[0150] Among them, 4 sheet-shaped workpieces A1 corresponding to the sliding block 22 are located on one side of the fixed block 21, and 4 sheet-shaped workpieces A1 corresponding to the fixed block 21 are located on the other side of the fixed block 21. The sheet-shaped workpieces A1 on both sides respectively form two groups of workpiece groups, which are respectively fed into a transfer module 3.

[0151] As Figure 12 , 13 shown, the transfer module 3 includes two parallel transfer chutes 31 and two dialing mechanisms 32 corresponding to the two transfer chutes 31 respectively. The two transfer chutes 31 are respectively aligned with both sides of the fixed block 21. The dialing mechanism 32 includes a dial fork 321 and a transfer cylinder 322. The transfer cylinder 322 drives the dial fork 321 to push the workpiece groups on both sides of the fixed block 21 into the two transfer chutes 31 respectively, and pushes the workpiece groups to move along the transfer chutes 31 to a spring assembly module.

[0152] The dual-path parallel assembly device of this embodiment has the following beneficial technical effects:

[0153] 1. The separation module 2 synchronously realizes the separation and grouping of the sheet-shaped workpieces A1 through the alternating displacement of the sliding block 22 and the fixed block 21, featuring high production efficiency.

[0154] 2. The two transfer chutes 31 of the transfer module 3 are docked with the output end of the separation module 2. The two groups of separated workpieces are directly aligned with the two transfer chutes 31, eliminating the need for additional operations by a transfer mechanism and effectively shortening the equipment length.

[0155] 3. There is a gap between each group of workpieces after separation, and the material pushing structure can accurately insert into the gap to position the sheet-shaped workpiece A1.

[0156] 4. Through the mechanical material distribution of the sliding block 22 and the fixed block 21, due to the simple logic, the cost is lower and the equipment failure rate is also lower.

[0157] As Figure 1 、 8 shown in Fig. -10, the dual-channel parallel assembly equipment of this embodiment further includes a spring assembly module, and the spring assembly module includes:

[0158] The material distribution device 4: includes a spring vibrating bowl, a feeding pipe 41, and two ejector pins that act alternately. The feeding pipe 41 conveys the spring A2 in the spring vibrating bowl to the assembly device through air pressure. The two ejector pins are the front ejector pin 42 and the rear ejector pin 43 respectively, which are used to insert into the feeding pipe 41 to block the spring A2. When both the front ejector pin 42 and the rear ejector pin 43 are inserted into the feeding pipe 41, a single spring A2 is blocked between the front ejector pin 42 and the rear ejector pin 43. When the front ejector pin 42 retracts, it allows a single spring A2 to pass through, and then the front ejector pin 42 inserts into the feeding pipe 41 to prepare to block the next spring A2. The rear ejector pin 43 retracts to release the next spring A2 between the front ejector pin 42 and the rear ejector pin 43, and then the rear ejector pin 43 inserts into the feeding pipe 41 and returns to the state when both the front ejector pin 42 and the rear ejector pin 43 extend. The cyclic action enables a single spring A2 to pass through in sequence.

[0159] The assembly device 5: includes a positioning sleeve 51 and a pressing rod 52. The positioning sleeve 51 is laterally provided with an introduction cylinder 54 connected to the feeding pipe 41. The introduction cylinder 54 is inclined with the positioning sleeve 51 and is sleeved at the bottom with the sheet-shaped workpiece A1 for coaxial positioning. After the spring A2 enters the positioning sleeve 51 from the feeding pipe 41, it is positioned with the sheet-shaped workpiece A1 through the positioning sleeve 51. The pressing rod 52 is driven by a downward pressing air cylinder 53 to press the spring A2 along the positioning sleeve 51, so that the spring A2 is installed on the protrusion at the top of the sheet-shaped workpiece A1.

[0160] The spring assembly equipment of this embodiment realizes the dual-channel parallel assembly of the spring A2 and the sheet-shaped workpiece A1 through the dual-station adaptation of the dual-channel feeding, significantly improving the assembly efficiency.

[0162] Vibrating disk 11: Conveys the sheet workpiece A1 to the linear vibrator 12;

[0163] Linear vibrator 12: Connects to the outlet of the vibrating disk 11 and outputs the sheet workpiece A1 to the buffer chute 13;

[0164] Buffer slider 14: Driven by the first feeding cylinder 15, moves between the first feeding position and the second feeding position;

[0165] Buffer chute 13: Is arranged inside the buffer slider 14 and is used to temporarily store the sheet workpiece A1;

[0166] Material blocking structure 16: When the buffer slider 14 is at the first feeding position, the material blocking structure 16 is located at the end of the buffer chute 13, used to block the sheet workpiece A1 in the buffer chute 13 and limit the number of sheet workpieces A1 according to the length of the buffer chute 13;

[0167] Paddle mechanism: Includes a paddle 17 and a second feeding cylinder 18, and the paddle 17 is correspondingly arranged with the separation channel B0 of the separation module 2;

[0168] When the buffer slider 14 is at the first feeding position, the buffer chute 13 is docked with the outlet of the linear vibrator 12. The linear vibrator 12 arranges the sheet workpieces A1 output from the vibrating disk 11 into a linear queue and pushes them into the buffer chute 13. When the sheet workpiece A1 moves to the end along the buffer chute 13, it is blocked by the material blocking structure 16, forming a workpiece queue with a preset number, such as 8 pieces / group;

[0169] When the buffer slider 14 is at the second feeding position, the end of the buffer chute 13 is docked with the separation channel B0 of the separation module 2. The second feeding cylinder 18 drives the paddle 17 to move horizontally, and pushes the workpiece queue in the buffer chute 13 into the separation channel B0;

[0170] After the pushing is completed, the paddle 17 resets, and the buffer slider 14 returns to the first feeding position, entering the next feeding cycle.

[0171] Furthermore, the material blocking structure 16 is fixedly arranged on the side of the fixed block 21 of the separation module 2 away from the separation channel B0 Figure 4 , its length direction is parallel to the moving direction of the buffer slider 14, and the end is in contact with the side surface of the fixed block 21, forming a limiting relay for the foremost sheet workpiece A1 in the buffer chute 13 through the fixed block 21 and the material blocking structure 16:

[0172] When the buffer slider 14 is at the first feeding position, the end of the buffer chute 13 is aligned with the material blocking structure 16, and the material blocking structure 16 blocks the foremost sheet workpiece A1;

[0173] When the buffer slider 14 moves towards the second feeding position, the side of the fixed block 21 gradually covers the end of the buffer chute 13 to form a relay block;

[0174] When the buffer slider 14 moves to the second feeding position, the end of the buffer chute 13 is misaligned with the side of the fixed block 21 and automatically aligns with the entrance of the separation channel B0.

[0175] The feeding module 1 of this embodiment has the following beneficial effects:

[0176] 1. Through the limit relay of the fixed material blocking structure 16 and the fixed block 21, it is ensured that the workpiece does not fall off during the displacement process;

[0177] 2. The material blocking structure 16 is fixedly arranged, without cylinders and sensors, with a simple structure and low cost;

[0178] 3. By using the misalignment cooperation between the side of the fixed block 21 and the buffer chute 13, automatic positioning of the buffer chute 13 and the separation channel B0 is achieved, without the need for an additional guiding mechanism.

[0179] As Figure 4-7 shown, the separation module 2 of this embodiment includes:

[0180] Base 24: Provided with a plurality of guiding grooves 241 extending transversely, and the plurality of guiding grooves 241 are arranged longitudinally;

[0181] Fixed block group: Comprising a plurality of convex-shaped fixed blocks 21 arranged equidistantly longitudinally. Each fixed block 21 includes a fixed part and a fixed boss 211 protruding from the top of the fixed part. The two transverse sides of the fixed boss 211 are symmetric inner positioning surfaces 251;

[0182] Slider group: Comprising a plurality of convex-shaped sliders 22 arranged equidistantly longitudinally. Each slider includes a sliding part and a sliding boss 221 protruding from the top of the sliding part. The two transverse sides of the sliding boss 221 are provided with symmetric inner positioning surfaces 251. The sliding part is in sliding cooperation with the guiding grooves 241 of the base 24 and is driven to move transversely by a transverse cylinder 23;

[0183] Positioning member 26: It has a U-shaped structure and is sleeved on the tops of the fixed boss 211 and the sliding boss 221. The middle part of the positioning member 26 is fixedly connected to the corresponding fixed boss 211 and sliding boss 221. There are two opposite outer positioning surfaces 252 on both sides of it. The two outer positioning surfaces 252 are symmetrically arranged, and a first workpiece groove 253 is formed between the two outer positioning surfaces 252 and the two inner positioning surfaces 251 of the corresponding fixed boss 211, and a second workpiece groove 254 is formed between the two outer positioning surfaces 252 and the two inner positioning surfaces 251 of the corresponding sliding boss 221. The first workpiece groove 253 and the second workpiece groove 254 are arranged opposite to each other in the transverse direction on both sides of the fixed boss 211 and the sliding boss 221. Both ends of the positioning member 26 respectively form an insertion and extraction gap 255 with the corresponding fixed part or sliding part. A plurality of insertion and extraction gaps 255 form a material pushing channel longitudinally. The material pushing mechanism 32 horizontally inserts into the first workpiece groove 253 and the second workpiece groove 254 from the material pushing channel to drive the sheet workpiece A1 to move longitudinally;

[0184] Material blocking mechanism: It includes a material blocking plate 271 and a material blocking air cylinder 272 for driving the material blocking plate 271 to move up and down.

[0185] Among them, when the sliding block 22 is in the overlapping position, the first workpiece grooves 253 of the fixed boss 211 and the sliding boss 221 are on the same side of the fixed boss 211 and are connected to form a first workpiece channel B1. The second workpiece grooves 254 of the fixed boss 211 and the sliding boss 221 are on the other side of the fixed boss 211 and are connected to form a second workpiece channel B2;

[0186] When the sliding block 22 is in the separated position, the second workpiece group of the sliding boss 221 and the first workpiece groove 253 of the fixed boss 211 are arranged alternately and connected longitudinally. The first workpiece channel B1 is switched to a temporary separation channel B0 for introducing a workpiece queue. The material blocking air cylinder 272 drives the material blocking plate 271 to extend to the end of the separation channel B0 to block the workpiece queue;

[0187] When the sliding block 22 moves from the separated position to the overlapping position, the sliding boss 221 drives the second workpiece groove 254 to disengage from the separation channel B0, pushes the corresponding sheet workpiece A1 to move into the second workpiece channel B2 on one side of the fixed boss 211 and forms a second workpiece group. At the same time, the sliding boss 221 drives the first workpiece groove 253 to communicate with the first workpiece groove 253 of the fixed boss 211, so that the separation channel B0 is automatically switched to the first workpiece channel B1. The sheet workpiece A1 corresponding to the fixed boss 211 remains in the first workpiece channel B1 and forms a first workpiece group. The material blocking air cylinder 272 drives the material blocking plate 271 to withdraw from the end of the first workpiece channel B1. The material pushing mechanism 32 transfers the separated first workpiece group and second workpiece group to two transfer chutes 31.

[0188] The separation module 2 of this embodiment has the following beneficial effects:

[0189] 1. The fixed block 21 and the sliding block 22 are in a convex shape, enabling a layered layout of the transverse cylinder 23 and the blanking mechanism 32. When the blanking mechanism 32 positions the sheet-like workpiece A1, it is located above the transverse cylinder 23 and does not require additional displacement for avoidance;

[0190] 2. The separation channel B0 serves as a temporary channel when introducing the workpiece queue. When the sliding block 22 moves to the overlapping position, it automatically switches to the first workpiece channel B1. At the same time, the separated sheet-like workpiece A1 automatically enters the second workpiece channel B2, which can be achieved only by the mechanical movement of the sliding block 22 without the intervention of sensors or programs, resulting in higher work efficiency;

[0191] 3. The inner positioning surface 251 and the outer positioning surface 252 cooperate to form a closed first workpiece groove 253 and second workpiece groove 254, which can ensure the continuous limitation of the sheet-like parts at all times. Even at the separation position, the alternately arranged outer positioning surface 252 and inner positioning surface 251 still form a continuous separation channel B0, reliably limiting the sheet-like workpiece A1 from both sides;

[0192] 4. The fixed block 21, the sliding block 22, and the positioning member 26 can all be replaced to adapt to sheet-like workpieces A1 of different sizes and shapes.

[0193] Preferably, the number of the fixed blocks 21 is equal to that of the sliding blocks 22, so that the number of the first workpiece groups is equal to that of the second workpiece groups. The number of sheet-like workpieces A1 in each of the first workpiece groups and the second workpiece groups is half of the number of sheet-like workpieces A1 in the workpiece queue. This can not only avoid waiting or misalignment in subsequent assembly stations due to mismatched workpiece numbers but also enable symmetric layout of components such as the dual-channel transfer module 3 and the blanking module, reducing costs.

[0194] Preferably, the inner positioning surface 251 is provided with a recessed positioning groove 2510. When the blanking mechanism 32 positions the sheet-like workpiece A1, it can be inserted into the positioning groove 2510, enabling the blanking mechanism 32 to come into more sufficient contact with the sheet-like workpiece A1 and increasing the reliability of limitation.

[0195] As Figure 12-13 shown, the transfer module 3 of this embodiment includes:

[0196] The guide rail 33: a long strip structure with a convex cross-section, provided with a guide boss 331 at the top. Symmetric inner guide surfaces 341 are provided on both transverse sides of the guide boss 331. The inner guide surfaces 341 are provided with guide grooves 3410 aligned with the positioning grooves 2510, and the blanking mechanism 32 can be inserted into the positioning grooves 2510;

[0197] Guide plate 35: It has a long strip U-shaped structure and is buckled on the guiding boss 331 of the guiding rail 33. The middle part is fixedly connected to the guiding boss 331. There are two opposite outer guiding surfaces 342 on both sides of it. The two outer guiding surfaces 342 are symmetrically arranged on both sides of the guiding boss 331 and form two transfer chutes 31 with the inner guiding surfaces 341 on both sides of the guiding boss 331. There is a feeding gap 343 formed between the two ends of the guide plate 35 and the side surface of the guiding rail 33 for the feeding mechanism 32 to insert. There is an avoidance groove 351 on the top of the guide plate 35 for the spring assembly module to pass through and install the spring A2 onto the sheet workpiece A1;

[0198] Among them, the two transfer chutes 31 on both sides of the guiding boss 331 are respectively the first transfer chute and the second transfer chute. The first transfer chute and the second transfer chute are respectively docked with the first workpiece channel B1 and the second workpiece channel B2 of the separation module 2. The two groups of feeding mechanisms 32 correspond to the first transfer chute and the second transfer chute respectively. The two groups of feeding mechanisms 32 can drive the sheet workpieces A1 in the first workpiece channel B1 and the second workpiece channel B2 to directly move into the corresponding transfer chutes 31 and move along the corresponding transfer chutes 31.

[0199] As Figure 12 shown, the feeding mechanism 32 of this embodiment includes:

[0200] Two groups of plugging and unplugging units. Each group of plugging and unplugging units includes two fork-shaped parts 321 and a plugging and unplugging cylinder 323 for driving the two fork-shaped parts 321 to move horizontally. Each fork-shaped part 321 is respectively provided with a positioning groove 324 corresponding to the number of sheet workpieces A1 in the corresponding workpiece group;

[0201] A transfer unit, including a transfer plate 325 and a transfer cylinder 322 for driving the transfer plate 325 to move longitudinally. The two groups of plugging and unplugging units are arranged on the transfer plate 325.

[0202] Preferably, each fork-shaped part 321 is respectively provided with a pressing unit corresponding to the number of sheet workpieces A1 in the corresponding workpiece group. The pressing unit includes a pressing block 326 and a pressing cylinder (not shown in the figure) for driving the pressing block 326 to move horizontally. When the spring assembly module assembles the spring A2 on the sheet workpiece A1, the pressing block 326 can press the sheet workpiece A1 against the guiding rail 33.

[0203] Preferably, the plugging cylinder is connected to the two fork-shaped parts 321 through a first floating joint, and the transfer cylinder 322 is connected to the transfer plate 325 through a second floating joint. The first floating joint and the second floating joint can compensate for the deviation during movement.

[0204] As Figure 3 shown, five workstations are sequentially arranged longitudinally in this embodiment, which are respectively:

[0205] Separation station C1: Aligned with the head end of the transfer module 3, equipped with a separation module 2. The separation module 2 divides the workpiece queue into a first workpiece group that is sent into the first transfer chute and a second workpiece group that is sent into the second transfer chute;

[0206] First assembly station C2: Located at the head end of the transfer module 3, equipped with a first spring assembly module for installing spring A2 onto the sheet-like workpiece A1 of the second workpiece group;

[0207] Second assembly station C3: Located in the middle of the transfer module 3, equipped with a second spring assembly module for installing spring A2 onto the sheet-like workpiece A1 of the first workpiece group;

[0208] Buffer station C4: Located at the end of the transfer module 3, where the first workpiece group and the second workpiece group converge and are synchronously sent to the inspection station C5;

[0209] Inspection station C5: Aligned with the end of the transfer module 3, equipped with an inspection module 6. The inspection module 6 synchronously sorts the first workpiece group and the second workpiece group.

[0210] In this embodiment, the transfer cylinder 322 can drive the transfer plate 325 to move between the first feeding position and the second feeding position;

[0211] When the transfer plate 325 moves to the first feeding position, the four forks 321 are respectively inserted into the sheet-like workpiece A1 at the separation station C1, the first assembly station C2, the second assembly station C3, and the buffer station C4;

[0212] When the transfer plate 325 moves to the second feeding position, the four forks 321 synchronously push the four groups of workpieces along the transfer chute 31 to the next station.

[0213] Specifically, the four forks 321 of the feeding mechanism 32 are, in sequence along the transfer direction, the first fork, the second fork, the third fork, and the fourth fork;

[0214] When the transfer plate 325 moves to the first feeding position, the plugging and unplugging cylinder 323 extends:

[0215] The first fork: Inserted into the separation station C1 to embed the newly entered workpiece group;

[0216] The second fork: Inserted into the first assembly station C2 to embed the workpiece group;

[0217] The third fork: Inserted into the second assembly station C3 to embed the workpiece group;

[0218] The fourth fork: Inserted into the buffer station C4 to embed the workpiece group.

[0219] When the transfer cylinder 322 drives the transfer plate 325 to move to the second feeding position:

[0220] The first fork 321 pushes the workpiece group at the separation station C1 to the first assembly station C2;

[0221] The second fork pushes the workpiece group at the first assembly station C2 to the second assembly station C3;

[0222] The third fork pushes the workpiece group at the second assembly station C3 to the buffer station C4;

[0223] The fourth fork pushes the workpiece group at the buffer station C4 to the detection station C5;

[0224] After the spring assembly module and the detection module 6 complete their operations, the plugging and unplugging cylinder 323 resets, driving the four forks 321 to be pulled out, and the transfer cylinder 322 drives the transfer plate 325 to reset to the first feeding position.

[0225] In the feeding mechanism 32 of this embodiment, the transfer chutes 31 on each side are synchronously operated by 4 forks 321 respectively, and the single transfer covers 5 stations, which can significantly shorten the beat and improve the assembly efficiency.

[0226] As Figure 14 shown, the detection module 6 of this embodiment includes a waste bin, a sorting channel, a dynamic support mechanism and a sensor unit;

[0227] The sorting channel includes:

[0228] Sorting boss 62: a strip-shaped structure with symmetrical inner cantilevers 621 on both transverse sides;

[0229] Sorting plate 63: a U-shaped structure is inverted on the sorting boss 62, with symmetrical outer cantilevers 631 on both sides. The two outer cantilevers 631 and the two inner cantilevers 621 are respectively opposite to form two sorting grooves 61. The two sorting grooves 61 correspond to the two transfer chutes 31 respectively. The waste bin is located below the sorting grooves 61. The width of the sorting groove 61 is greater than the thickness of the sheet workpiece A1 and less than the outer diameter of the spring A2.

[0230] The dynamic support mechanism includes:

[0231] Support platform 64: located between the sorting groove 61 and the waste bin, initially supporting the bottom of the sheet workpiece A1;

[0232] Slide table cylinder 65: drives the support platform 64 to move horizontally to expose the entrance of the waste bin.

[0233] The sensor unit includes: a sensor. The sorting plate 63 is provided with a detection hole 632 corresponding to the sensor, and the sensor detects the installation state of the spring A2 through the detection hole 632.

[0234] The detection process is as follows:

[0235] 1. Workpiece pre-positioning:

[0236] The sheet workpiece A1 enters the sorting channel from the transfer chute 31, and its middle part is embedded in the sorting groove 61. The support table 64 is in the initial position to support the bottom of the sheet workpiece A1.

[0237] 2. Mechanical sorting:

[0238] The support table 64 moves out: The sliding table cylinder 65 drives the support table 64 to move out laterally, and the waste bin inlet is exposed below the sorting groove 61;

[0239] Qualified product retention: For the workpiece with the spring A2 installed, since the outer diameter of the spring A2 is greater than the width of the sorting groove 61, the spring A2 is stuck above the inner cantilever 621 and the outer cantilever 631, preventing the workpiece from falling;

[0240] Rejected product removal: The workpiece without the spring A2 installed directly falls into the waste bin.

[0241] 3. Sensor sorting:

[0242] Scan through the detection hole 632 to check whether the spring A2 exists. If the spring A2 is missing but the workpiece does not fall, such as being stuck, or the installation posture of the spring A2 is inclined, the sensor triggers an alarm or a secondary rejection.

[0243] The detection module 6 of this embodiment realizes mechanical sorting through the differential design of the dimensions of the spring A2 and the sorting groove 61, which has the characteristics of high accuracy and low cost. It can also combine the double detection of the sensor digital display. Through the complementarity of mechanical and electrical detection methods, the missed detection rate can be significantly reduced. It can be understood that sorting can also be performed only through one of the mechanical and sensor methods, which all fall within the protection scope of the present invention.

[0244] As Figure 8-9 shown, the material distribution device 4 of this embodiment includes four feeding pipes 41. Each feeding pipe 41 is respectively provided with two alternately operating front ejector pins 42 and rear ejector pins 43. The four front ejector pins 42 are linked and driven by one ejector pin cylinder, and the four rear ejector pins 43 are linked and driven by another ejector pin cylinder;

[0245] The assembly device 5 includes four positioning sleeves 51 corresponding to the four feeding pipes 41 respectively. The sides of the four positioning sleeves 51 are provided with guiding cylinders 54 connected to the feeding pipes 41. The four positioning sleeves 51 are arranged on a positioning seat driven by a positioning cylinder. The positioning cylinder drives the positioning seat to move up and down, driving the positioning sleeves 51 to sleeved on the sheet workpiece A1 to achieve axial positioning. Each of the four positioning sleeves 51 is provided with a pressure rod 52. The pressure rod 52 is linked by a lower pressing cylinder 53 driving a lower pressing plate. The lower pressing cylinder 53 drives the four pressure rods 52 to press down through the lower pressing plate, and at the same time installs four springs on the sheet workpiece A1. Through the cooperation of the four feeding pipes 41 and the four pressure rods 52, four-way simultaneous assembly is realized, and the assembly efficiency is higher.

[0246] This embodiment also provides a dual-path parallel assembly method, including the following steps:

[0247] Feeding step: The sheet-shaped workpiece A1 is sorted into a workpiece queue of a predetermined number by the feeding module 1 and output to the separation module 2 in preset groups.

[0248] Separation step: The workpiece queue is divided into two groups of workpiece groups by the alternating movement of the fixed block 21 and the sliding block 22 of the separation module 2. The sliding block 22 is driven by the transverse cylinder 23 to move between the separation position and the coincidence position. When the sliding block 22 is in the separation position, a separation channel B0 is formed to introduce the workpiece queue; when the sliding block 22 moves to the coincidence position, the corresponding workpiece group is pushed laterally to one side of the fixed block 21, and the other workpiece group remains in place.

[0249] Transfer step: The two separated workpiece groups are synchronously transferred to two parallel transfer chutes 31 by the dialing mechanism 32 of the transfer module 3 and move along the transfer chutes 31 to the subsequent workstations.

[0250] Assembly step: At the assembly workstations corresponding to the two transfer chutes 31, the spring A2 is installed at the preset position of the sheet-shaped workpiece A1.

[0251] Detection step: The assembled workpieces are sorted by the detection module 6 to remove the workpieces without the spring A2 installed or with unqualified installation.

[0252] Further, the separation step includes:

[0253] The sliding block 22 moves to the separation position, and the fixed block 21 and the sliding block 22 are horizontally misaligned to form a separation channel B0 to introduce the workpiece queue.

[0254] The sliding block 22 moves from the separation position to the coincidence position, pushing the corresponding workpiece group laterally to one side of the fixed block 21, and the other workpiece group remains in the original position of the fixed block 21.

[0255] The material blocking cylinder 272 drives the material blocking plate 271 to withdraw from the end of the separation channel B0, and the dialing mechanism 32 synchronously inserts into the gap between the first workpiece group and the second workpiece group after separation to complete the separation and positioning of the two groups of workpieces.

[0256] Further, the transfer step includes:

[0257] The transfer cylinder 322 drives the transfer plate 325 to move to the first dialing position, and the plug-in and pull-out cylinder 323 drives the fork 321 to horizontally extend, so that the first fork inserts into the gap between the workpiece groups at the separation station C1, the second fork inserts into the gap between the workpiece groups at the first assembly station C2, the third fork inserts into the gap between the workpiece groups at the second assembly station C3, and the fourth fork inserts into the gap between the workpiece groups at the buffer station C4.

[0258] The transfer cylinder 322 drives the transfer plate 325 to move to the second feeding position, driving the first fork to push the workpiece group at the separation station C1 to the first assembly station C2, the second fork to push the workpiece group at the first assembly station C2 to the second assembly station C3, the third fork to push the workpiece group at the second assembly station C3 to the buffer station C4, and the fourth fork to push the workpiece group at the buffer station C4 to the inspection station C5;

[0259] After the spring assembly module completes the assembly, the plug-in cylinder 323 resets the fork 321, and the transfer cylinder 322 drives the transfer plate 325 to return to the first feeding position to enter the next cycle.
