Abstract
Description
Technical Field
[0001] This application relates to automated production equipment, and more particularly to an automatic steel sheet insertion device and a method for inserting steel sheets. Background Technology
[0002] Figure 1 The single-ended wire harness shown has multiple connecting plates A1 inside, and steel plates need to be inserted on both sides to maintain the spacing and stability between the steel plates. The steel plates are stamped structural parts, and the structure of the stamped product is as follows. Figure 2 As shown, steel sheet B and strip C are an integral structure. Inserting the steel sheet into the single-ended wire harness requires separating the strip from the steel sheet. The strip and steel sheet are connected by a pressure wire structure, and precise shearing force must be applied during separation to prevent deformation of the steel sheet. In existing technology, the processes of inserting the steel sheet and separating the strip are completed in two separate pieces of equipment, thus extending the production cycle of the steel sheet insertion process. Summary of the Invention
[0003] The technical problem to be solved by this application is to provide a device that integrates automatic steel sheet insertion and automatic steel sheet separation functions.
[0004] According to one aspect of this application, an automatic steel sheet insertion device includes a carrier, an insertion device, and a cutting device. The carrier includes a positioning platform for placing a single-ended wire harness and a pressing mechanism disposed above the positioning platform. The insertion device includes a clamping mechanism and a first power element. The clamping mechanism is used to clamp the steel sheet, and the first power element drives the clamping mechanism to move along a first direction to insert the steel sheet into a slot on the side of the single-ended wire harness. The cutting device includes a scraper block, a second power element, and a third power element. The scraper block has several grooves arranged side by side along a second direction on the side corresponding to the positioning platform. The first direction and the second direction are perpendicular to each other on a horizontal plane. The second power element drives the scraper block to move along the first direction, and the third power element drives the scraper block to move along the second direction. The scraper block moves simultaneously along the first and second directions. When the edge of the strip is inserted into the groove of the scraper block, the strip will be pushed by two directions. The steel sheet is inserted into the single-head wire harness and remains stationary. The scraper block causes the strip and the steel sheet to separate at the wire pressing structure, thus completing the automatic insertion and automatic separation of the steel sheet.
[0005] According to one embodiment of this application, the clamping mechanism includes a base plate, a sliding plate, an S-shaped tension sensor, and a clamping plate assembly. A first linear guide rail is provided on the side of the base plate, and the sliding plate is slidably connected to the first linear guide rail. The clamping plate assembly is fixedly installed on the side of the sliding plate. A fixing block is provided on one side of the base plate relative to the positioning platform. The S-shaped tension sensor is located between the fixing block and the sliding plate. The fixing block and the sliding plate are respectively fixedly connected to the two beam arms of the S-shaped tension sensor. When the clamping plate assembly inserts the steel sheet into the single-ended wire harness, the protrusion on the steel sheet is blocked, and the clamping plate assembly receives a counterforce. The sliding plate slightly retracts along the first linear guide rail. At this time, the S-shaped tension sensor collects the counterforce signal in real time and feeds it back to the control system. When the steel sheet is fully inserted into the single end, the counterforce on the clamping plate assembly decreases, and the S-shaped tension sensor collects the counterforce signal in real time and feeds it back to the control system. The control system determines whether the steel sheet has been inserted correctly based on the real-time feedback signal from the S-shaped tension sensor. If the reaction force does not fall back within the preset time threshold range, the control system determines that the steel sheet and the single-headed wire harness are not aligned, and the first power element immediately drives the clamping plate assembly to move backward to avoid damage to the steel sheet and the single-headed wire harness.
[0006] According to one embodiment of this application, the clamping plate assembly includes a first clamping plate, a second clamping plate, and a first cylinder. The first clamping plate is fixedly connected to the side of the slide plate, and the second clamping plate is located on the side of the first clamping plate opposite to the slide plate. The first clamping plate has two lugs located above and below the second clamping plate, respectively. The end of a shaft in the second clamping plate is inserted into the corresponding lug. A roller is mounted on one end of the second clamping plate opposite to the positioning platform. The first cylinder drives a wedge to insert between the roller and the first clamping plate, causing the second clamping plate to rotate around its axis, thus forming a clamping state between the first and second clamping plates. Preferably, a spring is provided between the first and second clamping plates. The first cylinder drives the wedge to retract from between the roller and the first clamping plate, and the spring returns to its original state, pushing the second clamping plate to rotate in the opposite direction to reset. The inclination angle of the wedge's inclined surface is 25°-30°, allowing the roller to move smoothly upwards along the inclined surface, precisely controlling the rotation angle and clamping force of the second clamping plate. During the wedge withdrawal process, the roller moves smoothly down the inclined plane, and the second clamping plate rotates synchronously under the action of spring preload, so that the clamping state of the clamping plate assembly is reliably released.
[0007] According to one embodiment of this application, an intermediate plate fixedly connected to the first clamping plate is provided between the first clamping plate and the second clamping plate. The intermediate plate has two limiting protrusions protruding towards the positioning platform at one end, forming a positioning groove at the end of the intermediate plate. The edge of the strip is first inserted into the positioning groove, the side of the strip fits against the edge of the intermediate plate, and the top and bottom contact the corresponding limiting protrusions. This achieves precise positioning of the strip before clamping, allowing the protrusions on the steel sheet to accurately embed into the corresponding slots of the single-head wire harness, thereby significantly improving the insertion accuracy and first-time insertion success rate of the steel sheet.
[0008] According to one embodiment of this application, a first carrier plate is provided on the top of the first power element, and the clamping mechanism and the second power element are fixed to the top of the first carrier plate; a second carrier plate is provided on the top of the third power element, and the first power element is fixed to the top of the second carrier plate; the first power element and the third power element are linear motor modules, and the second power element is a cylinder.
[0009] According to one embodiment of this application, the carrier includes a base, an upright plate, and a side-pushing mechanism. The upright plate is fixed to the top of the base, and the positioning platform is fixed to the side of the upright plate. A second linear guide rail is provided on the base along the second direction. The side-pushing mechanism includes a gripper cylinder and a push plate. The gripper cylinder is slidably connected to the second linear guide rail and is driven to move by a second cylinder installed on the top of the base. A push plate located between the positioning platform and the clamping plate assembly is installed on the fingers of the gripper cylinder. The push plate has a clearance hole for the gripping end of the clamping plate assembly to pass through. Preferably, one end of the push plate relative to the gripper cylinder is bent to form a push block, and the push block has several longitudinally arranged protruding teeth on one side corresponding to the positioning platform. The single-headed wire harness is placed on the positioning platform for initial positioning. The second cylinder drives the push plate to move into position along the second direction. The fingers of the gripper cylinder close, and the push plate pushes the single-headed wire harness to move along the first direction, completing the lateral pre-positioning of the single-headed wire harness on the positioning platform. After the push plate completes the lateral pre-positioning, the gripper cylinder remains closed, and the second cylinder drives the push plate to move backward a certain distance along the second direction, so that the single-headed wire harness moves into position along the second direction, completing the longitudinal positioning of the single-headed wire harness on the positioning platform.
[0010] According to one embodiment of this application, a guide plate is provided below the positioning platform, and a collection box is provided at the end of the guide plate. After the scraper blocks separate the material strip from the steel sheet, the material strip automatically slides down the guide plate into the collection box, realizing automatic waste recycling.
[0011] According to another aspect of this application, the method for inserting steel sheets using the aforementioned automatic steel sheet insertion equipment includes the following steps: S1, place the single-head wire harness on the positioning platform for initial positioning; insert the side of the strip with steel sheet into the positioning groove of the middle plate for positioning; the first cylinder drives the second clamping plate to rotate and clamp the strip. S2, the second cylinder drives the gripper cylinder to move along the second linear guide rail to the position, the fingers of the pneumatic gripper close, and the pusher pushes the single-head wire harness to the middle of the positioning platform; then, the second cylinder drives the gripper cylinder to move back a distance along the second linear guide rail, and the pusher moves the single-head wire harness to the correct position; finally, the pressing mechanism moves downward to fix the single-head wire harness on the positioning platform. S3, the first power element drives the clamping plate assembly to move towards the positioning platform and inserts the steel sheet into the slot on the side of the single-head wire harness; S4, the first cylinder drives the inclined wedge to retreat, the clamping plate assembly releases the material belt, and the first power element drives the clamping plate assembly to retreat; S5, the second power element drives the scraper block to move towards the positioning platform, and at the same time, the third power element drives the scraper block to move along the second direction; after the edge of the material strip enters the groove of the scraper block, it will move together with the scraper block, so that the material strip is separated from the steel sheet.
[0012] In summary, this application has the integrated technical advantages of single-head wire harness and automatic steel sheet positioning, automatic insertion and automatic waste separation, which significantly improves the insertion accuracy and production stability of steel sheets.

Detailed Implementation
[0014] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0015] Example
[0016] Figure 1 The single-headed wire harness shown includes a housing A, inside which are several layers of connecting plates A1. The spacing between adjacent connecting plates needs to be controlled to ensure the accuracy of the inserts. Steel plates B are inserted into both sides of the housing to achieve precise positioning of the connecting plates and stable assembly within the housing. Each steel plate B has an insertion part B1 that inserts between two adjacent connecting plates. Each insertion part has a protruding structure B2, which provides guidance and restraint during insertion. The protruding structure engages with a slot in the housing to fix the steel plate within the housing.
[0017] Figure 3 and Figure 4 The automatic steel sheet insertion equipment shown includes a carrier 1, a sheet insertion device 2, and a cutting device 3. Figure 4 The horizontal direction is the X-axis, labeled as the first direction X, and the vertical direction is the Y-axis, labeled as the second direction Y.
[0018] The carrier 1 includes a base 11, a vertical plate 12, a positioning platform 13, a pressing mechanism 14, and a side-pushing mechanism 15. The positioning platform is used to accurately position the single-head wire harness, and the pressing mechanism presses down to reliably fix the wire harness housing. The pressing mechanism can be a manual quick clamp or a cylinder-driven pressing assembly. Figure 7 and Figure 8As shown, the positioning platform 13 includes a horizontally arranged support plate 131 and a positioning block 132 mounted on the support plate. Two plates on the rear side of the housing are inserted into the positioning block. The upright plate 12 is fixed to the top of the base 11, the positioning block 132 is fixed to one side of the upright plate 12, and the support plate 131 is fixed to the bottom of the positioning block 132. A second linear guide rail 16 and a second cylinder 17 are provided on the base along a second direction. The side-pushing mechanism includes a gripper cylinder 151 and a pusher plate 152. The gripper cylinder is slidably connected to the second linear guide rail 16 and is driven to move by the second cylinder 17. The fingers of the gripper cylinder are equipped with pushers 152 located outside the positioning platform. The gripper cylinder drives the two pushers 152 to move inward, and the pushers push the single-headed wire harness to move along the first direction, completing the lateral pre-positioning of the single-headed wire harness on the positioning platform. The push plate 152 is bent at one end relative to the gripper cylinder to form a push block 153. The push block 153 has several longitudinally arranged protruding teeth 154 on one side corresponding to the positioning platform. After the push plate 152 completes its lateral pre-positioning, the gripper cylinder remains closed. The second cylinder 17 drives the push plate to retract a certain distance in the second direction. The protruding teeth of the push block 153 contact the front side of the single-headed wire harness, causing the single-headed wire harness to move into position in the second direction, completing the longitudinal positioning of the single-headed wire harness on the positioning platform 13. The pressing mechanism presses the single-headed wire harness downwards onto the support plate, thus completing the positioning and clamping of the single-headed wire harness.
[0019] This equipment can simultaneously insert steel plates B on both sides. Each side of the carrier 1 is equipped with an insertion device 2 and a cutting device 3. (See also...) Figure 5 The insert device includes a clamping mechanism 21 and a first power element 22. The first power element drives the clamping mechanism to move along a first direction. The cutting device 3 includes a scraper block 31, a second power element 32, and a third power element 33. The scraper block has several grooves 34 arranged in parallel along a second direction on the side of the positioning platform 13. The second power element drives the scraper block to move along the first direction, and the third power element drives the scraper block to move along the second direction. A linear motor module 1 arranged along the first direction is provided on each side of the carrier. A first carrier plate 5 is mounted on the top slide of the linear motor module 1. A linear motor module 2 arranged along the second direction is provided below the carrier. A second carrier plate 4 is mounted on the top slide of the linear motor module 2. The linear motor module 1 is fixed to the top of the second carrier plate. The first power element is the linear motor module 1, the second power element is a double-rod cylinder, and the third power element is the linear motor module 2. The clamping mechanism and the double-rod cylinder are fixed to the top of the first carrier plate 5.
[0020] The clamping mechanism 21 includes a base plate 211, a slide plate 212, an S-shaped tension sensor 213, and a clamping plate assembly. The base plate is fixed to the top of the first carrier plate 5. A first linear guide rail 214 is provided on the side of the base plate, and the slide plate 212 is slidably connected to the first linear guide rail. The clamping plate assembly is fixedly installed on the side of the slide plate 212. A fixing block 215 is provided on the side of the base plate relative to the positioning platform. The S-shaped tension sensor is located between the fixing block and the slide plate 212. The fixing block and the slide plate are respectively fixedly connected to the two beam arms of the S-shaped tension sensor.
[0021] See Figure 6 The clamping assembly includes a first clamping plate 216, a second clamping plate 217, an intermediate plate 218, and a first cylinder 219. The first clamping plate is fixedly connected to the side of the slide plate 212. The intermediate plate is disposed between the first and second clamping plates and is fixedly connected to the first clamping plate. Two limiting protrusions 219 extending towards the positioning platform 13 are provided at one end of the intermediate plate, forming positioning grooves at the ends of the intermediate plate 218. The edge of the strip is first inserted into the positioning groove, the side of the strip fits against the edge of the intermediate plate, and the top and bottom contact the corresponding limiting protrusions, achieving precise positioning of the strip before clamping. The first clamping plate 216 has two lugs 220 located above and below the second clamping plate 217, respectively. The ends of the shafts in the second clamping plate are inserted into the corresponding lugs. A roller 221 is mounted on one end of the second clamping plate relative to the positioning platform. A first cylinder drives a wedge 222 to insert between the roller and the first clamping plate, causing the second clamping plate to rotate around its axis, thus clamping the first and second clamping plates together. A spring 223 is installed between the first and second clamping plates. A first cylinder 219 drives the wedge to retract from between the roller and the first clamping plate 216. Driven by the spring force, the second clamping plate rotates in the opposite direction to reset. The inclination angle of the wedge's inclined surface is preferably 25°-30°. The roller moves smoothly forward along the inclined surface of the wedge, precisely controlling the rotation angle and clamping force of the second clamping plate. During the wedge retraction process, the roller moves smoothly backward along the inclined surface, and the second clamping plate rotates synchronously under the spring preload, reliably releasing the clamping state of the clamping plate assembly.
[0022] See Figure 7The push plate is provided with a clearance hole 155 for the clamping end of the clamping plate assembly to pass through. When the clamping plate assembly inserts the steel sheet into the single-ended wire harness, the protrusion mechanism on the steel sheet is blocked, and the clamping plate assembly is subjected to a counterforce. The slide plate 212 retracts slightly along the first linear guide rail 214. At this time, the S-type tension sensor 213 collects the counterforce signal in real time and feeds it back to the control system. After the steel sheet is fully inserted into the single-ended wire harness, the counterforce on the clamping plate assembly decreases, and the S-type tension sensor collects the counterforce signal in real time and feeds it back to the control system. The control system determines whether the steel sheet has been inserted in place based on the real-time feedback signal from the S-type tension sensor. If the value of the counterforce does not fall back within the preset time threshold range, the control system determines that the steel sheet and the single-ended wire harness are not aligned, and the first power element 22 immediately drives the clamping plate assembly to retract to avoid damage to the steel sheet and the single-ended wire harness. The control system then triggers the positioning and correction process, driving the side push mechanism to apply a fine-tuning force to the single-head wire harness along the second direction, so that the end of the wire harness is axially aligned with the steel sheet insertion port; after alignment is completed, the first power element restarts and continues to complete the steel sheet insertion action.
[0023] After the clamping state of the clamping plate assembly is released, linear motor module one drives the clamping plate assembly to retract to its original position, while linear motor module two and the double-rod cylinder drive the scraper block 31 to move simultaneously along the first and second directions. The edge of the strip is engaged in one of the grooves 34 of the scraper block, and the strip is then subjected to thrust in two directions. Since the steel sheet remains stationary when inserted into the single-head wire harness, the scraper block 31 pushes the strip along the pressing structure to bend it at a certain angle, and the strip and steel sheet are separated at the pressing structure. A guide plate 7 is provided below the positioning platform 13, and a collection box 8 is provided at the end of the guide plate. After the scraper block 31 separates the strip from the steel sheet, the strip automatically slides down the guide plate into the collection box, realizing automatic waste recycling.
[0024] After the strip is separated from the steel sheet, the linear motor module two and the double-rod cylinder drive the scraper block to reset, the pressing mechanism and the side pushing mechanism release the single-head wire harness, remove the assembled single-head wire harness, replace it with the next single-head wire harness to be assembled, and enter the next cycle.
