Description

Technical Field

[0001] This invention relates to the field of material transfer technology, specifically to a material production synchronous docking device. Background Technology

[0002] With technological advancements and increased production efficiency, people are increasingly pursuing high levels of automation in production equipment. This reduces the labor intensity of operators and ensures consistent product quality. Therefore, companies not only require high levels of automation when selecting new production lines, but also are undertaking automation upgrades to older, non-automated production lines. This not only saves labor costs but also guarantees consistent product quality.

[0003] However, during the automation upgrade of old production lines, the original design philosophy primarily relied on manual loading and unloading, neglecting the cycle time of preceding and following processes. For example, if the preceding production cycle was faster than the following cycle, manual loading would wait until a certain number of workpieces accumulated in the faster-cycle preceding process before placing them in the slower-cycle following process. However, with automation, directly placing workpieces from the preceding process into the following process would inevitably lead to workpiece accumulation in the latter due to the different cycle times, causing product quality issues. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a synchronous docking device for material production, which solves the problem of workpiece accumulation caused by different cycle times at the front and rear of the equipment.

The power assembly component is connected to a linear module component through a connecting plate. The linear module component is equipped with a workstation switch. Both the power assembly component and the linear module component are connected to a controller.

[0008] The powertrain components include a frame plate fixedly connected to the bottom of the connecting plate, a conveyor frame slidably connected to the underside of the frame plate, a receiving frame fixedly connected to the bottom of the conveyor frame, a roller conveyor assembly at the bottom of the receiving frame, a drive cylinder fixedly connected to the bottom of the frame plate away from the preceding equipment, the output end of the drive cylinder fixedly connected to the conveyor frame, forward and backward position switches respectively provided on both sides of the cylinder body of the drive cylinder, a vertically arranged limit cylinder fixedly connected to the end of the conveyor frame away from the preceding equipment, a downward and upward position switches respectively provided on both sides of the cylinder body of the limit cylinder, a limit plate fixedly connected to the output end of the limit cylinder, a material supply switch at the top of the receiving frame, and a guide plate fixedly connected to the inner side of the receiving frame in the feeding direction.

[0009] Preferably, the roller conveyor assembly includes a first drive motor, which is fixedly connected to the bottom of the receiving frame. The first drive motor is electrically connected to a controller. A drive sprocket is fixedly connected to the output end of the first drive motor. A power roller is uniformly rotatably connected to the inner side of the receiving frame. The power roller is perpendicular to the feeding direction. A driven sprocket is fixedly connected to one end of the power roller. Adjacent driven sprockets are connected by chains. The drive sprocket is connected to the driven sprocket at one end of the receiving frame by a chain.

[0010] Preferably, guide rods are fixedly connected to both sides of the bottom width direction of the frame plate, and four bearing seats are evenly arranged at the top of the material conveying frame. Linear bearings are arranged inside the bearing seats, and the four linear bearings are respectively sleeved on the outside of the two guide rods.

[0011] Preferably, both ends of the bottom of the limiting plate are fixedly connected to limiting rods, and an elastic layer is provided on the outer side of the bottom of the limiting rods. The end of the receiving rack away from the preceding equipment is fixedly connected to a limiting groove corresponding to the limiting rod.

[0012] Preferably, a mounting rod is fixedly connected to the top of the receiving rack, the mounting rod is set perpendicular to the feeding direction, and the material switches are evenly arranged at the bottom of the mounting rod, with the material switches and guide plates interleaved.

[0013] Preferably, the material conveying rack is an aluminum profile assembly, and the material receiving rack is a steel support.

[0014] Preferably, the linear module component includes a linear guide rail and two linear module brackets. The station switches are evenly arranged along the length of the linear guide rail. A slider is slidably connected to the linear guide rail. A connecting plate is fixedly connected to the top of the slider. The linear guide rail is fixedly connected between the two linear module brackets. A second drive motor is fixedly connected to the top of one linear module bracket. The second drive motor is connected to a controller. A lead screw is fixedly connected to the output end of the second drive motor. The end of the lead screw away from the second drive motor is rotatably connected to the top of the linear module bracket away from the second drive motor. The lead screw is threadedly connected to the slider.

[0015] Preferably, the controller is fixedly connected to the top of the connecting plate, and the controller is connected to the work position switch, roller conveyor assembly, drive cylinder, forward position switch, backward position switch, limit cylinder, downward position switch, upward position switch and material present switch via signal lines.

[0016] The operation method of the synchronous docking device includes the following steps:

[0017] S1. Original point receiving position

[0018] The origin position corresponds to the position of the workstation switch directly in front of the preceding equipment. When the power assembly is at the origin position, the workstation switch directly in front of the preceding equipment is enabled, the drive cylinder is in the extended state, that is, the forward position switch is enabled, and the limit cylinder is in the extended state, that is, the downward position switch is enabled. At this time, the limit plate is directly in front of the receiving rack, the roller conveyor assembly operates, and the workpiece conveyed by the preceding equipment is transferred to the inside of the receiving rack. The guide plate guides the workpiece, so that the workpiece is conveyed by the roller conveyor assembly to the area directly below the material switch. The limit plate restricts the workpiece from continuing to move forward.

[0019] S2. Origin Point Feeding

[0020] After the material receiving rack senses the workpiece, it sends a feedback signal to the controller. After receiving the feedback signals from all the material receiving switches, the controller sends control signals to the roller conveyor assembly and the drive cylinder respectively. The roller conveyor assembly stops running, the drive cylinder retracts, and when the rearward position switch is enabled, the drive cylinder remains in the retracted state. At the same time, the rearward position switch sends a feedback signal to the controller.

[0021] S3. Workstation Delivery

[0022] Multiple workstation switches correspond one-to-one with each workstation. When the drive cylinder is in the retracted state, it indicates that the powertrain component is in its original posture. When the controller receives the feedback signal from the backward positioning switch, it transmits a control signal to the linear module component. The linear module component transports the powertrain component to a workstation in sequence through the connecting plate. After the workstation switch corresponding to that workstation senses the powertrain component, it transmits a feedback signal to the controller. The controller transmits a control signal to the linear module component, causing the linear module component to stop transporting the powertrain component.

[0023] S4. Material sorting operation

[0024] When the controller receives the feedback signal from the station switch, it sends a control signal to the limit cylinder, causing the limit cylinder to retract. After the upward limit switch is enabled, the limit cylinder remains retracted. When the upward limit switch is enabled, it sends a feedback signal to the controller. When the controller receives the feedback signal from the upward limit switch, it controls the limit cylinder to extend again after a certain delay. During the delay period, the limit plate is released from the workpiece. The controller sends a control signal to the roller conveyor assembly, which then transfers the workpiece in the receiving rack to the corresponding position on the subsequent equipment.

[0025] S5. Reset Operation

[0026] After the limit cylinder extends again, the downward position switch is enabled, and the limit cylinder remains in the extended state. At the same time as the downward position switch is enabled, a feedback signal is sent to the controller. After receiving the feedback signal, the controller sends a control signal to the linear module component. The linear module component transports the powertrain component to the origin position. The station switch directly in front of the preceding equipment is enabled. At the same time as the station switch is enabled, a feedback signal is sent to the controller. After receiving the feedback signal, the controller sends a control signal to the drive cylinder, and the drive cylinder extends. When the forward position switch is enabled, the drive cylinder remains in the extended state, and the reset is complete.

[0027] S6. Material Retransfer

[0028] After resetting, the docking equipment follows the above operating procedure to transfer subsequent workpieces again. During the station delivery process, when the controller receives the feedback signal from the backward positioning switch, it transmits a control signal to the linear module component. The linear module component then transports the powertrain component to the next station in sequence through the connecting plate. When the next station is the last station, the linear module component transports the powertrain component to the first station through the connecting plate, so that the slower subsequent equipment is synchronized with the faster preceding equipment.

[0029] (III) Beneficial Effects

[0030] This invention provides a synchronous docking device for material production. It has the following beneficial effects:

[0031] 1. This invention uses a linear module component to transport a power assembly component with a power roller conveyor assembly, thereby transferring workpieces. Workpieces produced by the preceding equipment are placed sequentially on different workstations of the subsequent equipment according to a predetermined order, perfectly solving the problem of difference in cycle time between the preceding and following processes. This enables the slower subsequent equipment to achieve synchronous docking with the preceding equipment, providing the possibility for automation transformation.

[0032] 2. This invention uses a mobile power roller conveyor device in conjunction with a guiding structure and a limiting structure to transfer workpieces. The docking device has strong adaptability to workpieces of different sizes. As long as the diameter of the workpiece is within a certain range, it can be transmitted to the next process through the power roller conveyor device. It is not necessary to configure a set of suction claw tooling or manual gripping machinery for each type of workpiece, which is convenient for changing workpiece types and saves time and effort in adjusting old production lines.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] like Figure 1-6 As shown, this embodiment of the invention provides a material production synchronous docking device, including a power assembly component 1 and a preceding device 2 and a following device 3 respectively disposed on both sides of the power assembly component 1. The power assembly component 1 is connected to a linear module component 5 through a connecting plate 4. A workstation switch 6 is provided on the linear module component 5. Both the power assembly component 1 and the linear module component 5 are connected to a controller 7.

[0048] The powertrain component 1 includes a frame plate 101 fixedly connected to the bottom of the connecting plate 4. A material conveyor 102 is slidably connected to the lower side of the frame plate 101. A receiving frame 103 is fixedly connected to the bottom of the material conveyor 102. A roller conveyor assembly is provided at the bottom of the receiving frame 103. A drive cylinder 108 is fixedly connected to the bottom of the frame plate 101 away from the preceding equipment 2. The output end of the drive cylinder 108 is fixedly connected to the material conveyor 102. A forward-positioning switch 109 and a backward-positioning switch 110 are respectively provided on both sides of the cylinder body of the drive cylinder 108. A vertically arranged limit cylinder 111 is fixedly connected to the end of the material conveyor 102 away from the preceding equipment 2. A downward-positioning switch 112 and an upward-positioning switch 113 are respectively provided on both sides of the cylinder body of the limit cylinder 111. The output end of the cylinder 111 is fixedly connected to a limit plate 114. A material receiving rack 103 is equipped with a material switch 115 on its top. A guide plate 116 is fixedly connected to the inner side of the receiving rack 103 in the feeding direction. The origin position corresponds to the position of the workstation switch 6 directly in front of the preceding equipment 2. When the power assembly 1 is at the origin position, the workstation switch 6 directly in front of the preceding equipment 2 is enabled, the drive cylinder 108 is extended, and the limit cylinder 111 is extended. At this time, the limit plate 114 is directly in front of the receiving rack 103. The roller conveyor assembly transfers the workpiece W conveyed by the preceding equipment 2 to the roller conveyor assembly. The guide plate 116 guides the workpiece W. Multiple guide plates 116 are set according to the number of products produced by the preceding equipment 2 each time, so that the workpiece W is guided. The roller conveyor assembly delivers the workpiece W directly below the material-containing switch 115. The limit plate 114 restricts the workpiece W from moving forward. The material-containing switch 115 on the receiving rack 103 senses the workpiece W and sends a feedback signal to the controller 7. After receiving feedback signals from all the material-containing switches 115, the controller 7 sends control signals to the roller conveyor assembly and the drive cylinder 108 respectively. The roller conveyor assembly stops running, the drive cylinder 108 retracts, and the conveyor rack 102 drives the receiving rack 103 and the roller conveyor assembly to slide along the rack plate 101 towards the subsequent equipment 3. When the backward positioning switch 110 is enabled, the drive cylinder 108 remains retracted. Simultaneously, the backward positioning switch 110 sends a feedback signal to the controller 7. Multiple station switches 6 correspond one-to-one with each station, driving... When cylinder 108 is in the retracted state, it indicates that powertrain component 1 is in its original posture. When controller 7 receives the feedback signal from the backward positioning switch 110, it transmits a control signal to the linear module component 5. The linear module component 5 transports powertrain component 1 sequentially to a workstation via the connecting plate 4. The workstation switch 6 corresponding to that workstation senses powertrain component 1 and transmits a feedback signal to controller 7. Controller 7 then transmits a control signal to linear module component 5, causing linear module component 5 to stop transporting powertrain component 1. Simultaneously, controller 7, upon receiving the feedback signal from workstation switch 6, transmits a control signal to limit cylinder 111, causing limit cylinder 111 to retract. After upward positioning switch 113 is enabled, limit cylinder 111 remains in the retracted state.When the upward positioning switch 113 is enabled, it sends a feedback signal to the controller 7. Upon receiving the feedback signal from the upward positioning switch 113, the controller 7, after a delay, controls the limit cylinder 111 to extend again. During this delay, the limit plate 114 releases the restriction on the workpiece W. The controller 7 sends a control signal to the roller conveyor assembly, which then transfers the workpiece W from the receiving rack 103 to the corresponding position on the subsequent equipment 3. After the limit cylinder 111 extends again, the downward positioning switch 112 is enabled, and the limit cylinder... 111 remains in the extended state. Simultaneously, the downward positioning switch 112 is enabled and transmits a feedback signal to the controller 7. Upon receiving the feedback signal, the controller 7 transmits a control signal to the linear module component 5. The linear module component 5 transports the powertrain component 1 to the origin position. The station switch 6 directly in front of the preceding equipment 2 is enabled. Simultaneously, this station switch 6 transmits a feedback signal to the controller 7. Upon receiving the feedback signal, the controller 7 transmits a control signal to the drive cylinder 108. The drive cylinder 108 extends. When the forward positioning switch 109 is enabled, the drive cylinder 10... 8. After resetting, the docking equipment, following the above operating procedure, transfers the subsequent workpiece W again. During the station delivery process, when the controller 7 receives the feedback signal from the backward positioning switch 110, it transmits a control signal to the linear module component 5. The linear module component 5 then sequentially transports the powertrain component 1 to the next station via the connecting plate 4. When the next station is the last station, the linear module component 5 transports the powertrain component 1 to the first station via the connecting plate 4, enabling the slower-paced downstream equipment 3 to synchronize with the faster-paced upstream equipment 2. The docking device can place the workpieces produced by the upstream equipment onto different stations of the downstream equipment 3 in a predetermined order, perfectly solving the problem of the difference in cycle time between the upstream and downstream processes. The downstream equipment 3 processes the product once in a shorter time than the upstream equipment 2. Using the docking device of this invention, the downstream equipment 3 can process multiple batches of products W produced by the upstream equipment 2 in the same batch without manual handling, enabling the slower-paced downstream equipment to complete synchronous docking with the upstream equipment, providing the possibility for automation transformation.

[0049] The roller conveyor assembly includes a first drive motor 104, which is fixedly connected to the bottom end of the receiving frame 103. The first drive motor 104 is electrically connected to the controller 7. A drive sprocket 105 is fixedly connected to the output end of the first drive motor 104. A power roller 106 is uniformly rotatably connected to the inner side of the receiving frame 103. The power roller 106 is perpendicular to the feeding direction. A driven sprocket 107 is fixedly connected to one end of the power roller 106. Adjacent driven sprockets 107 are connected by chains. The drive sprocket 105 is connected to the driven sprocket 107 at one end of the receiving frame 103 by a chain. When the controller 7 transmits a control signal to the roller conveyor assembly, the first drive motor 104 drives the drive sprocket 105 to rotate. The drive sprocket 105 drives the driven sprocket 107 and the power roller 107 connected to the driven sprocket 107 through the chain. 6. The workpiece W is received and distributed via the power roller 106. The linear module component 5 drives the power assembly component 1 to transfer to each workstation via the connecting plate 4. The drive cylinder 108 of the power assembly component 1, in conjunction with the forward positioning switch 109, the backward positioning switch 110, the material supply switch 115, the workstation switch 6, and the controller 7, drives the material conveyor 102, the receiving rack 103, and the roller conveyor assembly to move. The workpiece is transferred via the mobile power roller conveyor in conjunction with the guide structure and the limiting structure. The docking device has strong adaptability to workpieces of different sizes. As long as the diameter of the workpiece is within a certain range, it can be transmitted to the next process via the power roller conveyor. It is not necessary to configure a set of suction claw tooling or gripping mechanical manual tooling for each type of workpiece, which is convenient for changing workpiece types and saves time and effort in adjusting old production lines.

[0050] Guide rods 117 are fixedly connected to both sides of the bottom width direction of the frame plate 101. Four bearing seats 118 are evenly arranged at the top of the material conveying frame 102. Linear bearings 119 are arranged inside the bearing seats 118. The four linear bearings 119 are respectively sleeved on the outside of the two guide rods 117. When the drive cylinder 108 drives the material conveying frame 102 to slide back and forth along the frame plate 101, the guide rods 117 cooperate with the linear bearings 119 and the bearing seats 118 to guide the material conveying frame 102.

[0051] Limiting rods 120 are fixedly connected to both ends of the bottom of the limiting plate 114. An elastic layer 121 is provided on the outer side of the bottom of the limiting rod 120. The end of the receiving rack 103 away from the preceding equipment 2 is fixedly connected to a limiting groove 122 corresponding to the limiting rod 120. When the driving cylinder 108 is in the extended state, the limiting rod 120 is inserted into the limiting groove 122. The elastic layer 121 reduces the impact force when the limiting rod 120 is inserted into the limiting groove 122. The limiting groove 122 cooperates with the limiting rod 120 to limit the limiting plate 114 in the front and rear directions, reducing the impact force on the output shaft of the limiting cylinder 111 when the workpiece W hits the limiting plate 114.

[0052] The top of the receiving rack 103 is fixedly connected to the mounting rod 123. The mounting rod 123 is set perpendicular to the feeding direction. The material switches 115 are evenly arranged at the bottom of the mounting rod 123. The material switches 115 and the guide plate 116 are interleaved. The guide plate 116 is set with multiple products according to the number of products produced by the preceding equipment in each processing. The number of material switches 115 is consistent with the number of products produced by the preceding equipment in each processing.

[0053] The material conveying rack 102 is an aluminum profile assembly, and the material receiving rack 103 is a steel support.

[0054] The linear module component 5 includes a linear guide rail 501 and two linear module brackets 503. Workstation switches 6 are evenly distributed along the length of the linear guide rail 501. A slider 502 is slidably connected to the linear guide rail 501. A connecting plate 4 is fixedly connected to the top of the slider 502. The linear guide rail 501 is fixedly connected between the two linear module brackets 503. A second drive motor 504 is fixedly connected to the top of one linear module bracket 503. The second drive motor 504 is connected to a controller 7. A lead screw 505 is fixedly connected to the output end of the second drive motor 504. The end of the lead screw 505 away from the second drive motor 504 is rotatably connected to the top of the linear module bracket 503 away from the second drive motor 504. The lead screw 505 is threadedly connected to the slider 502. The linear module component 5 drives the lead screw 505 to rotate via the second drive motor 504. The lead screw 505, in conjunction with the linear guide rail 501, drives the slider 502, the connecting plate 4 fixed relative to the slider 502, and the power assembly component 1 to slide along the linear guide rail 501.

[0055] The controller 7 is fixedly connected to the top of the connecting plate 4. The controller 7 is connected to the work position switch 6, the roller conveyor assembly, the drive cylinder 108, the forward position switch 109, the backward position switch 110, the limit cylinder 111, the downward position switch 112, the upward position switch 113, and the material switch 115 via signal lines.

[0056] Example 2:

[0057] like Figure 7-11 As shown, this embodiment of the invention provides an operation method for a synchronous docking device, including the following steps:

[0058] S1. Original point receiving position

[0059] The origin position corresponds to the position of the workstation switch 6 directly in front of the preceding equipment 2. When the power assembly component 1 is at the origin position, the workstation switch 6 directly in front of the preceding equipment 2 is enabled, the drive cylinder 108 is in the extended state, that is, the forward position switch 109 is in the enabled state, the limit cylinder 111 is in the extended state, that is, the downward position switch 112 is in the enabled state. At this time, the limit plate 114 is directly in front of the receiving rack 103. The roller conveyor assembly operates and transfers the workpiece W conveyed by the preceding equipment 2 to the inside of the receiving rack 103. The guide plate 116 guides the workpiece W so that the workpiece W is conveyed by the roller conveyor assembly to the area directly below the material switch 115. The limit plate 114 restricts the workpiece W from continuing to move forward.

[0060] S2. Origin Point Feeding

[0061] After the material receiving rack 103 senses the workpiece W, the material receiving switch 115 transmits a feedback signal to the controller 7. After receiving the feedback signals from all the material receiving switches 115, the controller 7 transmits control signals to the roller conveyor assembly and the drive cylinder 108 respectively. The roller conveyor assembly stops running, the drive cylinder 108 retracts, and the material conveyor 102 drives the material receiving rack 103 and the roller conveyor assembly to slide along the rack plate 101 toward the subsequent equipment 3. When the rearward position switch 110 is enabled, the drive cylinder 108 remains in the retracted state, and at the same time, the rearward position switch 110 transmits a feedback signal to the controller 7.

[0062] S3. Workstation Delivery

[0063] Multiple workstation switches 6 correspond one-to-one with each workstation. When the drive cylinder 108 is in the retracted state, it indicates that the powertrain component 1 is in its original posture. When the controller 7 receives the feedback signal from the backward positioning switch 110, it transmits a control signal to the linear module component 5. The linear module component 5 transports the powertrain component 1 to a workstation in sequence through the connecting plate 4. After the workstation switch 6 corresponding to that workstation senses the powertrain component 1, it transmits a feedback signal to the controller 7. The controller 7 transmits a control signal to the linear module component 5, causing the linear module component 5 to stop transporting the powertrain component 1.

[0064] S4. Material sorting operation

[0065] When the controller 7 receives the feedback signal from the station switch 6, it transmits a control signal to the limit cylinder 111, causing the limit cylinder 111 to retract. After the upward positioning switch 113 is enabled, the limit cylinder 111 remains in the retracted state. When the upward positioning switch 113 is enabled, it transmits a feedback signal to the controller 7. When the controller 7 receives the feedback signal from the upward positioning switch 113, it controls the limit cylinder 111 to extend again after a certain delay. During the delay period, the restriction of the limit plate 114 on the workpiece W is released. The delay time is 5 seconds. The controller 7 sends a control signal to the roller conveyor assembly, and the roller conveyor assembly transfers the workpiece W in the receiving rack 103 to the position corresponding to the station on the subsequent equipment 3.

[0066] S5. Reset Operation

[0067] After the limit cylinder 111 extends again, the downward position switch 112 is enabled, and the limit cylinder 111 remains in the extended state. At the same time as the downward position switch 112 is enabled, it transmits a feedback signal to the controller 7. After receiving the feedback signal, the controller 7 transmits a control signal to the linear module component 5. The linear module component 5 transports the powertrain component 1 to the origin position. The station switch 6 directly in front of the preceding equipment 2 is enabled. At the same time as the station switch 6 is enabled, it transmits a feedback signal to the controller 7. After receiving the feedback signal, the controller 7 transmits a control signal to the drive cylinder 108. The drive cylinder 108 extends. When the forward position switch 109 is enabled, the drive cylinder 108 remains in the extended state, and the reset is completed.

[0068] S6. Material Retransfer

[0069] After resetting, the docking equipment follows the above operating procedure to transfer the subsequent workpiece W again. During the station delivery process, when the controller 7 receives the feedback signal from the backward positioning switch 110, it transmits a control signal to the linear module component 5. The linear module component 5 transports the powertrain component 1 to the next station in sequence through the connecting plate 4. When the next station is the last station, the linear module component 5 transports the powertrain component 1 to the first station through the connecting plate 4. When the next station matches the station corresponding to the station switch 6 directly in front of the preceding equipment 2, the powertrain component 1 is already in the station to be delivered. The linear module component 5 does not move the powertrain component 1. The powertrain component 1 performs material distribution at the original position, so that the slower-paced subsequent equipment 3 and the faster-paced preceding equipment 2 are synchronized.

A material production synchronous docking device, comprising a powertrain component and preceding and following equipment respectively disposed on both sides of the powertrain component, characterized in that: The powertrain component is connected to the linear module component via a connecting plate. The linear module component is equipped with a work station switch. Both the powertrain component and the linear module component are connected to the controller. The powertrain components include a frame plate fixedly connected to the bottom of the connecting plate, a material conveying frame slidably connected to the underside of the frame plate, a receiving frame fixedly connected to the bottom of the material conveying frame, a roller conveyor assembly at the bottom of the receiving frame, a drive cylinder fixedly connected to the bottom of the frame plate away from the preceding equipment, the output end of the drive cylinder fixedly connected to the material conveying frame, a forward and backward stop switch respectively provided on both sides of the cylinder body of the drive cylinder, a vertically arranged limit cylinder fixedly connected to the end of the material conveying frame away from the preceding equipment, a downward and upward stop switch respectively provided on both sides of the cylinder body of the limit cylinder, a limit plate fixedly connected to the output end of the limit cylinder, a material supply switch at the top of the receiving frame, and a guide plate fixedly connected to the inner side of the receiving frame in the feeding direction; The operation method of the material production synchronous docking device includes the following steps: S1. Original point receiving position The origin position corresponds to the position of the workstation switch directly in front of the preceding equipment. When the power assembly is at the origin position, the workstation switch directly in front of the preceding equipment is enabled, the drive cylinder is in the extended state, that is, the forward position switch is enabled, and the limit cylinder is in the extended state, that is, the downward position switch is enabled. At this time, the limit plate is directly in front of the receiving rack, the roller conveyor assembly operates, and the workpiece conveyed by the preceding equipment is transferred to the inside of the receiving rack. The guide plate guides the workpiece, so that the workpiece is conveyed by the roller conveyor assembly to the area directly below the material switch. The limit plate restricts the workpiece from continuing to move forward. S2. Origin Point Feeding After the material receiving rack senses the workpiece, it sends a feedback signal to the controller. After receiving the feedback signals from all the material receiving switches, the controller sends control signals to the roller conveyor assembly and the drive cylinder respectively. The roller conveyor assembly stops running, the drive cylinder retracts, and when the rearward position switch is enabled, the drive cylinder remains in the retracted state. At the same time, the rearward position switch sends a feedback signal to the controller. S3. Workstation Delivery Multiple workstation switches correspond one-to-one with each workstation. When the drive cylinder is in the retracted state, it indicates that the powertrain component is in its original posture. When the controller receives the feedback signal from the backward positioning switch, it transmits a control signal to the linear module component. The linear module component transports the powertrain component to a workstation in sequence through the connecting plate. After the workstation switch corresponding to that workstation senses the powertrain component, it transmits a feedback signal to the controller. The controller transmits a control signal to the linear module component, causing the linear module component to stop transporting the powertrain component. S4. Material sorting operation When the controller receives the feedback signal from the station switch, it sends a control signal to the limit cylinder, causing the limit cylinder to retract. After the upward limit switch is enabled, the limit cylinder remains retracted. When the upward limit switch is enabled, it sends a feedback signal to the controller. When the controller receives the feedback signal from the upward limit switch, it controls the limit cylinder to extend again after a certain delay. During the delay period, the limit plate is released from the workpiece. The controller sends a control signal to the roller conveyor assembly, which then transfers the workpiece in the receiving rack to the corresponding position on the subsequent equipment. S5. Reset Operation After the limit cylinder extends again, the downward position switch is enabled, and the limit cylinder remains in the extended state. At the same time as the downward position switch is enabled, a feedback signal is sent to the controller. After receiving the feedback signal, the controller sends a control signal to the linear module component. The linear module component transports the powertrain component to the origin position. The station switch directly in front of the preceding equipment is enabled. At the same time as the station switch is enabled, a feedback signal is sent to the controller. After receiving the feedback signal, the controller sends a control signal to the drive cylinder, and the drive cylinder extends. When the forward position switch is enabled, the drive cylinder remains in the extended state, and the reset is complete. S6. Material Retransfer After resetting, the docking equipment follows the above steps to transfer subsequent workpieces again. During the station delivery process, when the controller receives the feedback signal from the backward positioning switch, it transmits a control signal to the linear module component. The linear module component then transports the powertrain component to the next station in sequence through the connecting plate. When the next station is the last station, the linear module component transports the powertrain component to the first station through the connecting plate, so that the slower subsequent equipment is synchronized with the faster preceding equipment.
