[0016] A control method for an automated production device for a telescopic rod, characterized in that the control method is as follows:

[0017] a. First, turn on the equipment through the PLC controller;

[0018] b. Use sensors installed on the inner rod rack and outer rod rack to sense whether there is an inner rod or outer rod at the discharge chute;

[0019] c. After the sensor senses the presence of an inner rod or an outer rod, it sends a signal to the PLC controller, which controls the inner rod feeding mechanism and the outer rod feeding mechanism to start, and runs to the discharge chute to take out the inner rod or the outer rod, and loads the materials at the same time; if the sensor does not sense the inner rod or the outer rod, or does not sense either, it sends a signal to the PLC controller, which controls the entire equipment to stop working and wait for the operator to refill the materials;

[0020] d. Inner rod loading: When the inner rod loading mechanism drives the inner rod to move to the inner rod supporting mechanism, the sensor installed on the inner rod clamping cylinder senses whether the inner rod is in place. When it is in place, the signal is transmitted to the PLC controller. The PLC controller controls the inner rod clamping cylinder to clamp the inner rod, and then the inner rod loading mechanism is reset, and the inner rod is ready for assembly;

[0021] e. External rod loading and processing; when the external rod loading mechanism transports the external rod to the bead rolling station to prepare for bead rolling, the external rod originally in the bead rolling station moves to the flaring stamping station to prepare for flaring stamping after completing the bead rolling work, and the external rod originally in the flaring stamping station moves to the external rod support mechanism to prepare for assembly after completing the processing, and then the external rod loading mechanism is reset to prepare for the next external rod loading;

[0022] f. When the sensor installed on the outer rod support frame senses the outer rod, the sensor installed on the inner rod clamping cylinder also senses the inner rod and sends a signal to the PLC controller, which controls the assembly mechanism to start;

[0023] g. Control the inner rod slider to drive the inner rod to move, so that one end of the inner rod moves to the guide clamping block, and at the same time, the limiter pushes out the limit block, and the limit block pushes one end of the outer rod to move to the guide clamping block, and then controls the guide clamping cylinder to drive the guide clamping block to clamp the inner rod and the outer rod;

[0024] h. Then the PLC controller controls the assembly pusher to drive the push rod to move. During the movement, the push rod contacts the inner rod and forms a thrust on the inner rod, so that the inner rod moves forward along the guide clamping block until the sensor B installed on the sensor bracket senses the assembly pusher;

[0025] i. After the sensor B senses the assembly pusher, it sends a signal to the PLC controller. At this time, one end of the inner rod has been inserted into the outer rod, and then the PLC controller controls the guide clamping cylinder to drive the guide clamping block to loosen; the assembly pusher continues to push the push rod, and the push rod continues to push the inner rod;

[0026] j. Until the sensor C senses the assembly pusher, the assembly pusher stops moving, and the assembly of the inner rod and the outer rod is completed;

[0027] k. Then the PLC controller controls the assembly pusher and the limiter to reset; at the same time, it controls the unloading mechanism to remove the telescopic rod on the outer rod support block and reset it after unloading;

[0028] l. When the sensors installed on the outer rod support frame and the inner rod slider do not sense the outer rod and the inner rod, and sensor A senses the reset of the assembly pusher and sends a signal to the PLC controller, the PLC controller controls the equipment to start the next inner rod and outer rod loading, processing and assembly cycle.

[0029] The present invention realizes automatic loading, processing, assembly and unloading of the telescopic rod through the arrangement and coordination of the PLC controller, the automatic loading mechanism, the forming mechanism and the assembly mechanism. The operator only needs to feed the material, which has high automation, high efficiency and low labor intensity.

[0030] By setting the bead rolling mechanism, the outer rod of the telescopic rod is automatically beaded before assembly, so that convex ribs protruding outwards and concave ribs recessed inwards are formed at both ends of the outer rod of the telescopic rod;

[0031] Through the setting of the damping forming mechanism, the expansion hole punching mechanism forms an expansion hole on the port at one end of the telescopic rod, and at the same time, the telescopic rod is punched, so that an elastic sheet with one side tilted inward is formed on the telescopic rod through punching, and at the same time, the other end of the telescopic rod is edged by the edge wrapping mechanism, which is highly efficient;

[0032] Through the setting of the assembly mechanism, the inner rod that has been processed in advance is inserted into the outer rod that has been processed to realize automatic assembly without manual operation, with high efficiency and low labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] Hereinafter, we will further explain the automatic production equipment of telescopic rods and the control method thereof according to the present invention with reference to the accompanying drawings.

[0056] See also Figure 1-Figure 21As shown in the figure, an automatic production equipment for telescopic rods and a control method thereof, comprising a frame 1 and a PLC controller 2 installed on the frame 1; it is characterized in that it also includes an automatic feeding mechanism 3 arranged on the frame 1 for feeding the telescopic rod body, a forming mechanism 4 for processing the telescopic rod body and an assembly mechanism 5 for assembling the telescopic rod; the automatic feeding mechanism 3 includes an inner rod feeding mechanism 31 for automatically feeding the inner rod of the telescopic rod and an outer rod feeding mechanism 3 for automatically feeding the outer rod of the telescopic rod. 2; the forming mechanism 4 comprises a rolling mechanism 41 for rolling the outer rod of the telescopic rod and a damping forming structure 42 for processing the outer rod of the telescopic rod to form a damping limit structure; the inner rod feeding mechanism 31 and the outer rod feeding mechanism 32 both comprise a fixing frame 33 mounted on the frame 1, a hopper 34 adjustable on the fixing frame 33, and a guide plate 35 mounted in the hopper 34 and adapted thereto; a discharge trough 362 for material limit and discharge is formed between the guide plates 35;

[0057] Through the arrangement and coordination of the PLC controller 2, the automatic feeding mechanism 3, the forming mechanism 4 and the assembly mechanism 5, the telescopic rod is automatically loaded, processed, assembled and unloaded. The operator only needs to add materials, which has a high degree of automation, high efficiency and low labor intensity. Through the arrangement of the rib rolling mechanism 41, the outer rod of the telescopic rod is automatically ribbed before assembly, and convex ribs protruding outward and concave ribs recessed inward are formed at both ends of the outer rod of the telescopic rod.

[0058] By setting the damping forming mechanism 42, the expansion punching mechanism 43 expands the port at one end of the telescopic rod and punches the telescopic rod at the same time, so that an elastic sheet with one side tilted inward is formed on the telescopic rod by punching, and the other end of the telescopic rod is edged by the edge wrapping mechanism 44, which is highly efficient.

[0059] By setting the assembly mechanism 5, the pre-processed inner rod is inserted into the processed outer rod to realize automatic assembly, without manual operation, with high efficiency and low labor intensity;

[0060] A single-rod discharge trough 362 is formed by the guide plates 35 and the guide plates 35, so that the discharge trough can only discharge single rod at a time; a sliding bar is provided on the fixed frame 33, and the hopper 34 includes a material channel plate slidably mounted on the sliding bar, and the material channel plate can slide on the sliding bar, so that the distance between the two material channel plates can be adjusted. The adjusted material channel plate is fixedly mounted on the sliding bar by tightening the screws; through the setting of the guide plate 35, the telescopic rod is limited and guided; through the setting of the discharge trough 362, only one telescopic rod can be output at a time, and after the telescopic rod is taken out, the subsequent telescopic rod automatically moves to the discharge trough 362.

[0061] Furthermore, the guide plate 35 is fixed on the hopper 34 at an angle toward the discharge slot 362 or is not fixed on the hopper 34. The guide plate can be directly fixed on the hopper to support and guide the material, or it can be movably installed on the support plate 81 to drive the guide plate 35 to vibrate through the vibrating feeder 8 to perform vibration feeding.

[0062] Furthermore, the hopper 34 is also provided with a support plate 81, on which a guide sleeve 82 is provided, a vibrating feeder 8 is provided at the bottom of the guide plate 35, a plurality of guide posts 83 adapted to the guide sleeve 82 are provided on the vibrating feeder 8, a buffer spring 84 is provided on the guide post 83, and the buffer spring 84 is located between the vibrating feeder 8 and the support plate 81; by installing the support plate 81 on the hopper 34, the support plate 81 supports and fixes the guide plate 35, the vibrating feeder 8 is installed at the bottom of the guide plate 35, and the vibrating feeder 8 drives the guide plate 35 to move. 5 is vibrated, thereby performing vibration feeding work, and there is no need to completely rely on the slope of the guide plate 35 for automatic feeding. Therefore, the slope of the guide plate 35 can be set to be relatively gentle, so that more inner rods or outer rods can be stored in the hopper 34, reducing the frequency of operators feeding, saving labor; the setting of the buffer spring 84 plays a buffering role on the vibration of the vibrating feeder 8, and at the same time, the guide plate 35 and the support plate 81 are movably connected through the cooperation of the guide column 83 and the guide sleeve 82, so as to avoid the vibration of the hopper 34 and the entire machine caused by the vibration of the vibrating feeder 8;

[0063] The vibrating feeder 8 can be a linear vibrator or a linear vibration motor.

[0064] Further, the inner rod feeding mechanism 31 also includes an inner rod lifting feeder 311 installed on the frame 1 by bolts, an inner rod horizontal mover 312 installed on the inner rod lifting feeder 311 by bolts, a feeding plate 313 installed on the inner rod horizontal mover 312 by bolts, and an inner rod frame 314 arranged on the feeding plate 313 for conveying the inner rod, an arc groove 315 is provided on the inner rod frame 314, and a sensor 7 is also installed on the inner rod frame 314;

[0065] The inner rod lifting feeder 311 drives the inner rod frame 314 to move upward until the inner rod on the inner rod frame 314 contacts the inner rod at the discharge slot 362, and then drives the inner rod to move upward and away from the discharge slot 362, and then drives the inner rod lifting feeder 311 and the inner rod to move to the inner rod supporting mechanism 51 through the inner rod horizontal mover 312. At the same time, the inner rod lifting feeder 313 drives the top plate 514 to move upward. When the inner rod moves to the inner rod supporting mechanism 51, the lifting feeder 311 drives the inner rod to move downward to the set position, and then supports and positions the inner rod through the top plate 514. Then, after the inner rod is clamped by the clamping claw 454 on the inner rod supporting mechanism 51, the inner rod horizontal mover 312 and the inner rod lifting device 513 are reset at the same time, completing the automatic feeding of the inner rod.

[0066] Further, the outer rod feeding mechanism 32 also includes an adjusting frame 321 installed on the frame 1 by bolts, an adjusting plate 322 adjustably installed on the adjusting frame 321, an outer rod lifter 323 installed on the adjusting plate 322 by bolts, an outer rod lifter 324 installed on the outer rod lifter 323 by bolts, an outer rod feeder 325 installed on the outer rod lifter 324 by bolts, an outer rod feeder 326 installed on the outer rod feeder 325 by bolts, and an outer rod material frame 327 installed on the outer rod feeder 326 in a uniform array by bolts; the outer rod material frame 327 is also provided with an arc groove 315, and the outer rod material frame 327 is also installed with a sensor 7; the adjusting frame 321 is provided with an adjusting rod, the adjusting plate 322 is provided with a slider slidably connected to the adjusting rod, the slider is provided with a locking screw for locking the slider and the slide rod, and the position of the adjusting plate 322 can be adjusted according to the length of the telescopic rod;

Then, the outer rod loading mechanism 32 drives the outer rod feeding rack 326 and the telescopic rod to move forward one position, and the outer rod just removed from the discharge chute 362 moves to the bead rolling station for bead rolling treatment, and the outer rod that has just completed the bead rolling treatment moves to the expansion stamping and hemming station for expansion stamping and hemming treatment. The outer rod that has completed the expansion stamping and hemming treatment moves to the outer rod support mechanism 52 of the assembly station to wait for assembly, and then the outer rod lifter 323 drives the outer rod feeding rack 326 to move downward and reset, and then the outer rod feeder 325 drives the outer rod feeding rack 326 to reset, preparing for the next outer rod loading.

[0068] Furthermore, the outer rod material rack 327 is also provided with a suction nozzle 328 that passes through the arc groove 315; through the setting of the suction nozzle, the suction nozzle is connected to a negative pressure suction device such as a fan through a pipeline, and through the setting of the suction nozzle 328, the suction nozzle 328 is connected to a negative pressure suction device such as a fan through a pipeline, and air is sucked through the negative pressure suction device such as the fan. When the outer rod is on the outer rod material rack 327, the suction force of the suction nozzle 328 sucks the outer rod onto the outer rod material rack 327, avoiding problems such as displacement or falling during the movement, which will cause the subsequent rolling and flaring processes to fail to operate normally.

After the telescopic rod is clamped by the material unloading clamping cylinder 63, the material unloading clamping cylinder 63 is reset. Then the material unloading mover 61 drives the material unloading and loading device 62, the material unloading clamping cylinder 63 and the telescopic rod to move outward. When moving to the material frame, the material unloading clamping cylinder 63 is controlled to release the clamping claw 454.

[0079] Working process of the present invention:

[0080] First, a device for processing the inner rod is configured. The device is provided with the outer rod feeding mechanism 32, the bead rolling mechanism 41 and the damping forming mechanism 42 in the present application. The difference is that the punch 436 and the punching structure are not required in the device. The inner rod is subjected to bead rolling, flaring and hemming processing by the device. The operator stacks the processed inner rods on the hopper 34 of the inner rod feeding mechanism 31; and at the same time, the unprocessed outer rods are stacked on the hopper 34 of the outer rod feeding mechanism 32.

[0081] Then the PLC controller 2 controls the device to start, and at the same time starts the suction fan or negative pressure suction device connected to the suction nozzle 328 through a pipeline. First, the sensor 7 on the inner rod frame 314 senses whether there is an inner rod at the discharge slot 362 above the inner rod frame 314. After sensing the presence of the inner rod, a signal is sent to the PLC controller 2. The PLC controller 2 controls the inner rod lifting feeder 311 to drive the inner rod frame 314 to move upward until the inner rod at the discharge slot 362 on the inner rod frame 314 contacts, drives the inner rod to move upward and leave the discharge slot 362, and then moves horizontally through the inner rod After the device 312 drives the inner rod lifting feeder 311 and the inner rod to move to the inner rod supporting mechanism 51, the inner rod lifting feeder 311 drives the inner rod to move downward to the set position, and the inner rod lifting device 513 drives the top plate 514 to move upward, and the top plate 514 supports and positions the inner rod. After the sensor 7 set on the inner rod supporting mechanism 51 senses the inner rod, it controls the inner rod clamping cylinder 512 to drive the clamping claw 454 to clamp the inner rod, and then the inner rod lifting feeder 311, the inner rod horizontal mover 312 and the inner rod lifting device 513 are reset to complete the automatic feeding of the inner rod;

[0082] At the same time, the sensor 7 installed on the outer rod material rack 327 of the outer rod loading mechanism 32 senses that there is an outer rod on the discharge slot 362 of the outer rod loading mechanism 32 and transmits the signal to the PLC controller 2. The PLC controller 2 controls the outer rod lifter 323 to drive the outer rod lifter 324 to move upward, the outer rod lifter 324 drives the outer rod feeder 325 to move upward, the outer rod feeder 325 drives the outer rod feeding rack 326 to move upward, the outer rod feeding rack 326 drives the outer rod material rack 327 to move upward, and the outer rod material rack 327 on the rear side takes the outer rod out of the discharge slot 362 and sucks the outer rod through the suction nozzle 328. At the same time, the other two outer rod material racks 327 move the outer rod on the outer rod material rack 327 to the rolling mechanism 41 and the expansion mechanism 42. The outer rod that has completed the processes of rolling, expanding, and punching and hemming at the punching mechanism 43 is removed, and then the outer rod feeding mechanism 32 drives the outer rod feeding rack 326 and the outer rod to move forward one position, and the moving distance is set by the PLC controller 2, and the moving distance is consistent each time. The outer rod that has just been removed from the discharge chute 362 moves to the rolling station for rolling, and the outer rod that has just completed the rolling moves to the expanding, punching and hemming station for expanding, punching and hemming. The outer rod that has completed the expanding, punching and hemming moves to the outer rod support mechanism 52 of the assembly station to wait for assembly, and then the outer rod lifter 323 drives the outer rod feeding rack 326 to move downward and reset, and then the outer rod feeder 325 drives the outer rod feeding rack 326 to reset, and prepares for the next outer rod loading;

[0083] When the sensors 7 installed on the outer rod support frame 521 and the inner rod clamping cylinder 512 both sense the presence of the outer rod and the inner rod, the PLC controller 2 controls the inner rod slider 511 to start, and the inner rod slider 511 drives the inner rod clamping cylinder 512 and the inner rod to move forward, and one end of the inner rod moves to the guide mechanism 53. At the same time, the limiter 542 is controlled to start, and the limiter 542 drives the limit block 543 to move forward. During the forward movement of the limit block 543, one end of the outer rod extends into the through hole 544 of the limit block 543 until the port is blocked by the limit recess 545. After that, the limit block 543 pushes the outer rod, and the limit block 543 pushes one end of the outer rod to move to the guide mechanism 53. Then the guide clamping cylinder 532 is started, driving the guide clamping block 533 to clamp the inner rod and the outer rod, which has a limiting effect on the position of the inner rod and the outer rod, and plays a guiding and positioning role for the movement of the inner rod; then the assembly pusher 551 is controlled Start, the assembly pusher 551 drives the push frame 552, and the push frame 552 drives the push rod 553 to move forward. In the process of moving forward, the push rod 553 contacts the other end of the inner rod and forms a thrust on it, pushing the inner rod to move forward along the matched guide clamping block 533. When the sensor B556 installed on the sensor bracket 554 senses the assembly pusher 551, one end of the inner rod has extended into the outer rod, and then the guide clamping cylinder 532 is controlled to drive the guide clamping block 533 to release the clamping, and the assembly pusher 551 continues to push the inner rod to insert into the outer rod until one end of the inner rod passes through the outer rod and extends out from the through hole 544 on the limit block 543. At the same time, the sensor C557 senses the assembly pusher 551, indicating that the assembly is completed. The assembly pusher 551 drives the push rod 553 to reset, and at the same time, the limiter 542 drives the limit block 543 to reset, and the telescopic rod is assembled;

[0084] After the telescopic rod is assembled, the material unloading and loading device 62 is started to drive the material unloading clamping cylinder 63 and the clamping claw 454 to move downward, and then the material unloading clamping cylinder 63 is reset after the telescopic rod is clamped by the material unloading clamping cylinder 63, and then the material unloading moving device 61 drives the material unloading and loading device 62, the material unloading clamping cylinder 63 and the telescopic rod to move outward, and when it moves to the material frame, the material unloading clamping cylinder 63 is controlled to release the clamping claw 454, and the telescopic rod falls into the material frame. After that, the material unloading moving device 61 is reset to complete the automatic unloading work;

[0085] When there are multiple telescopic rods, only the two previously assembled inner rods of the three telescopic rods need to be assembled in the same way, and the same method can be used for multiple rods.

[0086] During the processing, when the sensor on the inner rod rack or the sensor on the outer rod rack does not sense the inner rod or outer rod, there are several situations.

[0087] 1) The inner rod or outer rod is stuck and does not fall into the discharge chute. At this time, the whole machine stops and waits for the operator to handle it;

[0088] 2) There is no material on the material channel plate and the material guide plate, and it needs to be replenished or all the materials in this batch have been loaded;

[0089] The PLC controller is used to set the time during which the sensor does not sense the inner rod or the outer rod. For example, the time is set to 20 seconds. The 20 seconds are the time for the operator to replenish materials or deal with a jam. If the waiting time exceeds 20 seconds, it means that all materials in this batch have been loaded. The PLC controller is used to control the inner rod at the loading station or the outer rod at the processing station to be processed and assembled, thereby avoiding leaving semi-finished products on the equipment.

[0090] The protection scope of the present invention is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present invention.

9. The control method of an automated production equipment for telescopic rods according to any one of claims 1 to 8, characterized in that: The control method is as follows: a. First, turn on the equipment through the PLC controller; b. Use sensors installed on the inner rod rack and outer rod rack to sense whether there is an inner rod or outer rod at the discharge chute; c. After the sensor senses the presence of an inner rod or an outer rod, it sends a signal to the PLC controller, which controls the inner rod feeding mechanism and the outer rod feeding mechanism to start, and runs to the discharge chute to take out the inner rod or the outer rod, and loads the materials at the same time; if the sensor does not sense the inner rod or the outer rod, or does not sense both, it sends a signal to the PLC controller, which controls the entire equipment to stop working and wait for the operator to refill the materials; d. Inner rod loading: When the inner rod loading mechanism drives the inner rod to move to the inner rod supporting mechanism, the sensor installed on the inner rod clamping cylinder senses whether the inner rod is in place. When it is in place, the signal is transmitted to the PLC controller. The PLC controller controls the inner rod clamping cylinder to clamp the inner rod, and then the inner rod loading mechanism is reset, and the inner rod is ready for assembly; e. External rod loading and processing; the external rod loading mechanism transports the external rod to the bead rolling station to prepare for bead rolling work. After the bead rolling work is completed, the external rod originally in the bead rolling station moves to the expansion stamping station to prepare for expansion stamping work. After the external rod originally in the expansion stamping station completes the processing, it moves to the external rod support mechanism to prepare for assembly work, and then the external rod loading mechanism is reset to prepare for the next external rod loading; f. When the sensor installed on the outer rod support frame senses the outer rod, the sensor installed on the inner rod clamping cylinder also senses the inner rod and sends a signal to the PLC controller, which controls the assembly mechanism to start; g. Control the inner rod slider to drive the inner rod to move, so that one end of the inner rod moves to the guide clamping block, and at the same time, the limiter pushes out the limit block, and the limit block pushes one end of the outer rod to move to the guide clamping block, and then controls the guide clamping cylinder to drive the guide clamping block to clamp the inner rod and the outer rod; h. Then the PLC controller controls the assembly pusher to drive the push rod to move. During the movement, the push rod contacts the inner rod and forms a thrust on the inner rod, so that the inner rod moves forward along the guide clamping block until the sensor B installed on the sensor bracket senses the assembly pusher; i. After the sensor B senses the assembly pusher, it sends a signal to the PLC controller. At this time, one end of the inner rod has been inserted into the outer rod, and then the PLC controller controls the guide clamping cylinder to drive the guide clamping block to loosen; the assembly pusher continues to push the push rod, and the push rod continues to push the inner rod; j. Until the sensor C senses the assembly pusher, the assembly pusher stops moving, and the assembly of the inner rod and the outer rod is completed; k. Then the PLC controller controls the assembly pusher and the limiter to reset; at the same time, it controls the unloading mechanism to remove the telescopic rod on the outer rod support block and reset it after unloading; l. When the sensors installed on the outer rod support frame and the inner rod slider do not sense the outer rod and the inner rod, and sensor A senses the reset of the assembly pusher and sends a signal to the PLC controller, the PLC controller controls the equipment to start the next inner rod and outer rod loading, processing and assembly cycle.
