Description

Technical Field

[0001] This invention relates to the field of automotive assembly equipment technology, and specifically to an automated assembly system and method for automotive parts. Background Technology

[0002] During the car assembly process, some parts need to be connected by inserting flexible inserts. For example, the car dashboard has multiple slots on its outer shell. Metal clips need to be inserted into the slots first, and then the dashboard is assembled with other parts of the car body using the metal clips.

[0003] When installing inserts, the workpiece must first be mounted on the positioning fixture, the insert is then picked up and inserted, and the workpiece is removed after insertion. All of these steps require manual completion. Therefore, there is a lack of an automated assembly system for automotive parts that can replace manual insertion and improve production efficiency. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, one of the objectives of this invention is to provide an automatic assembly system for automotive parts. Through the cooperation of a robotic arm and multiple clamping parts, multiple inserts can be automatically clamped and inserted. Each time a workpiece is inserted, the robotic arm only needs to make one round trip between the clamping position and the positioning component. After the insertion is completed, the robotic arm can drive the clamping part to unload the material, reducing manual operation and improving production efficiency.

[0005] The technical solution adopted in this invention is as follows: An automated assembly system for automotive parts includes a controller, a feeding assembly, a robotic arm, and multiple positioning assemblies. The feeding assembly is used to transport inserts, the positioning assemblies are used to fix the workpieces, and the free end of the robotic arm is equipped with a clamping assembly, which includes multiple clamping parts, each of which can be engaged with the back of the insert. The controller controls the feeding component to transfer the workpiece to a preset position; The controller controls the robotic arm to move above the feeding assembly. The robotic arm drives a single clamping part to clamp into the back of the insert at the preset position. The robotic arm adjusts the position of the other clamping parts. At the same time, the feeding assembly transmits the next insert to the preset position, so that the next clamping part is aligned with the back of the insert at the preset position and clamps in again, until the number of inserts clamped on the clamping assembly is the same as the number of inserts required for a single workpiece. The controller controls the robotic arm that has completed clamping to move above the positioning component. The robotic arm adjusts the orientation of the clamping part and inserts the inserts one by one into the workpiece. After the insertion is completed, the robotic arm adjusts the orientation of one of the clamping parts and uses the clamping part to push the assembled workpiece away from the positioning component.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of the robotic arm and multiple clamping parts, multiple inserts can be automatically clamped and inserted. After insertion, the robotic arm can drive the clamping parts to unload, reducing manual operation and improving production efficiency. The clamping component clamps the inserts required for a single workpiece at a time. Each time a workpiece is inserted, the robotic arm only needs to make one round trip between the clamping position and the positioning component, which improves production efficiency.

[0007] In a preferred embodiment of the present invention, the number of positioning components is two, and each positioning component includes a vertically arranged positioning plate. The inner side of each positioning plate is provided with a lower stepped groove, an upper positioning groove, a side positioning groove, and a plurality of central insertion holes.

[0008] Beneficial effects: 1. By setting two positioning components, while the clamping arm is holding the insert and inserting and pushing out one workpiece, another workpiece can be installed on the other positioning component. Therefore, after the clamping arm finishes clamping the new insert, it can directly insert the next workpiece, which improves processing efficiency. 2. After the protruding part of the workpiece is inserted into the central insertion hole, it may be too tight and difficult to remove manually. By setting a central insertion hole, after the robotic arm completes the insertion of the insert for a single workpiece, it can adjust the position of the clamping part so that the single clamping part is aligned with one of the central insertion holes, pushing the protruding part of the workpiece away from the central insertion hole, making it easier for the operator to remove the workpiece. When the workpiece is pushed out, it can remind the operator to change to the next workpiece, avoiding the operator's misjudgment that the workpiece has not been inserted and the robotic arm to repeatedly insert it, which would lead to equipment failure.

[0009] In a preferred embodiment of the present invention, the clamping assembly further includes a rotating plate, which is installed at the free end of the robotic arm. Each clamping part includes a clamping rod, and the end of the clamping rod is provided with a locking block or slot for inserting an insert. Multiple clamping rods are evenly spaced and circumferentially mounted on the rotating plate.

[0010] Beneficial effects: 1. Some inserts have a V-shaped back. By setting a locking block to insert into the back of the insert, the insert itself is elastic, so that the first clamping rod passes through the locking block and can clamp this type of insert; for inserts with a protrusion on the back, a through groove is set to engage with the protrusion and can clamp this type of insert. 2. When inserting the insert into the workpiece, adjacent clamping rods may interfere with the workpiece's movement. By setting the circumferential spacing evenly, interference is less likely to occur. Furthermore, when programming the robotic arm, the spacing between each clamping rod is the same, which facilitates the setting of the movement path.

[0011] In a preferred embodiment of the present invention, the rotating plate is provided with a through hole, the center line of the through hole is collinear with the center line of the rotating plate, the rotating plate is provided with a plurality of rectangular holes arranged radially in the circumferential direction, and the rotating plate is provided with a plurality of threaded holes arranged radially in the circumferential direction, one end of each threaded hole is connected to the corresponding rectangular hole, and the other end of each threaded hole is connected to the through hole. Each of the clamping rods includes an adjusting rod and a sliding block. The side wall of each adjusting rod is provided with threads and is screwed into the corresponding threaded hole. Each sliding block is slidably connected to the corresponding rectangular hole. One end of each adjusting rod is rotatably connected to the corresponding sliding block. The other end of each adjusting rod extends out of the corresponding threaded hole. The sliding block includes a left block and a right block. The bottom of both the left block and the right block is provided with a fan-shaped stepped groove. The left block is close to the right block and installed in a rectangular hole. The two fan-shaped stepped grooves form a circular stepped groove. One end of the adjusting rod is rotatably installed in the circular stepped groove.

[0012] Beneficial effects: 1. The length of the clamping rod can be adjusted individually. Since there are many different types of workpieces, in order to avoid interference when inserting fasteners, the clamping rod with adjustable length is set to adapt to different workpieces. 2. By setting up left and right blocks, during installation, rotate the adjusting rod so that one end of the adjusting rod passes through the rectangular hole. At this time, one end of the adjusting rod is located on the outside of the rotating plate. By symmetrically and tightly attaching the left and right blocks to the adjusting rod, and then turning the adjusting rod, the left and right blocks are retracted into the rectangular hole, thus completing the installation. No other bolts or clips are required, making disassembly and assembly convenient.

[0013] In a preferred embodiment of the present invention, a correction component is also included. The controller has a preset robotic arm movement path for different workpieces. The correction component is used to detect the overall length of each clamping part and adjust the movement path of the robotic arm each time it clamps.

[0014] Beneficial effects: The controller needle preset clamping part matches the corresponding path for the insertion path of different workpieces, and then adds or subtracts the corresponding difference to correct the movement path, saving the time of manual correction and improving production efficiency.

[0015] In a preferred embodiment of the present invention, the correction component includes a distance sensor located above the position where the insert is snapped into place by the clamping part.

[0016] Beneficial effects: By setting a distance sensor, when the robotic arm is in the initial position, it drives multiple gripping parts to rotate. The distance sensor records the changes in values. The value when the end of the gripping part is vertically upward is the shortest distance. Since the center position of the rotating plate in the initial position is fixed, the length of the end of each gripping part can be calculated.

[0017] The second objective of this invention is to provide an automated assembly method for automotive parts, applied to the aforementioned automated assembly system for automotive parts, comprising the following steps: S1: The controller controls the feeding component to transfer the workpiece to the preset position. The controller controls the robotic arm to move the clamping component above the preset position so that the lowest clamping part is aligned with the workpiece at the preset position. At this time, the robotic arm is in the initial position. S2: The controller controls the robotic arm to move the clamping part downward, so that the lowest clamping part is engaged with the back of the workpiece, and then the clamped workpiece is lifted up; the feeding component transfers the next workpiece to the preset position, and the robotic arm drives the clamping component to rotate, so that the next clamping part is aligned with the workpiece at the preset position. S3: Repeat step S2 until the number of inserts clamped on the clamping assembly meets the number of inserts required for a single workpiece. S4: The controller controls the robotic arm to transfer the clamped insert to the top of the fixed workpiece. The robotic arm adjusts the orientation of each clamping part according to the slot position of the workpiece, and inserts the insert into the slot one by one until the insertion of the insert for a single workpiece is completed.

[0018] In a preferred embodiment of the present invention, the correction component further includes a distance sensor, which is located above a preset position. In step S1, The distance sensor first detects whether the workpiece at the preset position has shifted. After the shift detection is completed, the controller controls the robotic arm to move the clamping assembly to the initial position. Then, the robotic arm drives the clamping assembly to rotate 360° to detect the shortest distance between the distance sensor and each clamping part.

[0019] In a preferred embodiment of the present invention, the number of positioning components is two, and each positioning component includes a vertically arranged positioning plate. Each positioning plate has a lower stepped groove, an upper positioning groove, a side positioning groove, and multiple central insertion holes on its inner side. In step S4... In a preferred embodiment of the present invention, in steps S1 and S2, whenever a workpiece is transferred to a preset position, a distance sensor is used to detect whether the workpiece at the preset position has been transferred to the correct position. If the workpiece has not been transferred to the correct position, the controller controls the feeding assembly to continue transferring until the workpiece is transferred to the correct position.

[0020] Beneficial effects: By setting a distance sensor, the distance between the workpiece and itself at a preset position is detected. When the workpiece is not transferred to the correct position, the detected value will be deviated, thereby determining whether the workpiece has been transferred to the correct position and ensuring that the clamping component can clamp accurately.

[0021] After the insertion of the insert into a single workpiece is completed, the controller controls the robotic arm to adjust the position of the corresponding clamping part so that the clamping part is aligned with the corresponding central insertion hole. The robotic arm then pushes the clamping part laterally to push the workpiece out of the positioning plate.

[0022] Beneficial effects: The above method replaces manual insertion and achieves automatic correction and automatic unloading, reducing the labor intensity of operators and improving production efficiency. Attached Figure Description

[0025] Typical embodiments embodying the features and advantages of the present invention will be specifically described in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0026] In the description of this application, the terms "first", "second", etc. are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] See Figure 1 As shown, this embodiment discloses an automatic assembly system for automotive parts, including a controller, a feeding component 1, a robotic arm 2, and multiple positioning components 3. Each positioning component 3 is used to fix a single workpiece 5. A clamping component 4 is installed at the free end of the robotic arm 2. The clamping component 4 includes multiple clamping parts, each of which can be inserted into the back of an insert. The robotic arm 2 drives the multiple clamping parts to clamp the required number of inserts for a single workpiece 5, and then drives the clamped inserts to be inserted into the workpiece 5 one by one. The robotic arm 2 drives the single clamping part to push the assembled workpiece 5 away from the positioning component 3.

[0028] In this embodiment, the insert is a metal buckle; the vibratory feeder transports and arranges the inserts so that they face the same direction. In other embodiments, the feeding assembly 1 can be a conveyor belt; the workpiece 5 is a dashboard housing for automobiles. The robotic arm 2 drives multiple clamping parts to move, and the clamping parts engage with the back of the insert to hold the insert. After clamping the required number of inserts for a single workpiece 5, the robotic arm 2 then drives multiple clamping parts and inserts to move to the vicinity of the workpiece 5, adjusts the orientation of the insert, and inserts the insert into the slot on the workpiece 5 to complete the automatic clamping; after the fastener is inserted into a single workpiece 5, the robotic arm 2 drives the clamping parts to push the workpiece 5 out.

[0029] Among them, see Figure 2 As shown, the clamping assembly 4 also includes a rotating plate 41, which is installed at the free end of the robotic arm 2. Each clamping part includes a clamping rod 42, and the end of the clamping rod 42 is provided with a locking block 43 or a locking groove for inserting an insert. Multiple clamping rods 42 are evenly spaced and circumferentially mounted on the rotating plate 41.

[0030] In this embodiment, the robotic arm 2 is a six-axis robotic arm 2. The rotating plate 41 is connected to the end drive shaft of the six-axis robotic arm 2 by bolts. The six-axis robotic arm 2 has high freedom and flexibility. When the workpiece 5 is on the tooling, the opening of the slot faces different directions. The six-axis robotic arm 2 can drive the clamped insert to be inserted at different angles, realizing automatic insertion and replacing manual operation. By setting a detachable rotating plate 41, different specifications of rotating plates 41 and clamping parts can be replaced to adapt to different specifications of workpieces 5 to be processed. In other embodiments, the robotic arm 2 can be a five-axis or four-axis robotic arm 2. The robotic arm 2 has a V-shaped back for some inserts. By setting a locking block 43, the back of the insert is inserted. The insert itself is elastic, so that the first clamping rod 42 can clamp this type of insert through the locking block 43. For inserts with a protrusion on the back, a through groove 44 is set to engage with the protrusion to clamp this type of insert. When the insert is inserted into the workpiece 5, adjacent clamping rods 42 may interfere with the workpiece 5. By setting them evenly in the circumferential interval, interference is less likely to occur. When the robotic arm 2 is programmed, the interval between each clamping rod 42 is the same, which makes it easy to set the motion path.

[0031] Among them, see Figure 3 As shown, there are two positioning components 3. Each positioning component 3 includes a vertically arranged positioning plate 31. The inner side of each positioning plate 31 is provided with a lower stepped groove 32, an upper positioning groove 33, a side positioning groove 34, and multiple central insertion holes 35.

[0032] In this embodiment, by setting two positioning components 3, during the process of the clamping arm clamping the insert and inserting and pushing out one of the workpieces 5, another workpiece 5 can be manually installed onto another positioning component 3. Therefore, after the clamping arm completes clamping the new insert, it can directly insert the next workpiece 5, which improves processing efficiency.

[0033] The card block 43 has limiting grooves on both sides, and the through groove 44 has grooves on both sides. By setting the limiting grooves and grooves, it is easier to snap the protruding part into place, and the protruding part can be limited.

[0034] Example 2: See Figure 4 and Figure 5As shown, based on Embodiment 1, the present invention also proposes an automatic assembly device for accessories. The rotating plate 41 is provided with a through hole 61, the center line of the through hole 61 is collinear with the center line of the rotating plate 41, the rotating plate 41 is provided with a plurality of rectangular holes 62 arranged radially in the circumferential direction, the rotating plate 41 is provided with a plurality of threaded holes 63 arranged radially in the circumferential direction, one end of each threaded hole 63 is connected to the corresponding rectangular hole 62, and the other end of each threaded hole 63 is connected to the through hole 61. Each of the clamping rods 42 includes an adjusting rod 64 and a sliding block 65. The side wall of each adjusting rod 64 is provided with threads and is screwed into the corresponding threaded hole 63. Each sliding block 65 is slidably connected to the corresponding rectangular hole 62. One end of each adjusting rod 64 is rotatably connected to the corresponding sliding block 65, and the other end of each adjusting rod 64 extends out of the corresponding threaded hole 63.

[0035] The operator inserts their hand into the through hole 61 and can rotate the corresponding adjusting rod 64. Since there is a threaded hole 63, the adjusting rod 64 rotates and moves radially along the rotating plate 41. Since the adjusting rod 64 is rotatably connected to the sliding block 65, the sliding block 65 slides along the rectangular hole 62, thereby adjusting the distance between the end of the sliding block 65 and the center of the through hole 61, thereby changing the overall length of each clamping rod 42.

[0036] Among them, see Figure 6 As shown, the sliding block 65 includes a left block 651 and a right block 652. Both the left block 651 and the right block 652 have fan-shaped stepped grooves 653 at their bottoms. The left block is tightly attached to the right block and installed within a rectangular hole. The two fan-shaped stepped grooves 653 form a circular stepped groove. One end of the adjusting rod 64 is rotatably installed within the circular stepped groove. By setting the left block 651 and the right block 652, during installation, rotating the adjusting rod 64 allows one end of the adjusting rod 64 to pass through the rectangular hole 62. At this time, one end of the adjusting rod 64 is located outside the rotating plate 41. By symmetrically attaching the left block 651 and the right block 652 tightly to the adjusting rod 64, and then turning the adjusting rod 64, the left block 651 and the right block 652 retract into the rectangular hole 62, thus completing the installation. No other bolts or locking pins are required, making disassembly and assembly convenient.

[0037] Example 3: Based on Embodiment 2, the present invention also proposes an automatic assembly device for accessories, which further includes a correction component. The controller has a preset movement path of the robotic arm 2 for different workpieces 5. The correction component is used to detect the overall length of each clamping part and adjust the movement path of the robotic arm 2 each time it clamps. The correction component includes a distance sensor, which is located above the position where the insert is clamped.

[0038] In this embodiment, for the installation of a single workpiece 5, the clamping arm needs to move from the initial position, insert the workpiece, assemble the workpiece 5, unload, and return to the initial position in sequence. During the above process, the movement path of the robotic arm 2 is the movement path preset in the controller. Since the shape and insertion position of each workpiece 5 are different, multiple movement paths need to be preset in sequence, and the corresponding path is matched according to the workpiece 5 being processed. By setting a distance sensor, when the robotic arm 2 is in the initial position, it drives multiple gripping parts to rotate. The distance sensor records the value changes. The value when the end of the gripping part is vertically upward is the shortest distance. Since the center position of the rotating plate 41 in the initial position is fixed, the length of the end of each gripping part can be calculated. Then, the corresponding difference is added or subtracted to correct the movement path, saving the time of manual correction and improving production efficiency. Because of the correction component, only a rough adjustment is needed for different workpieces 5. The path can be modified to compensate for the difference, saving the time of repeated manual calibration.

[0039] In other embodiments, the correction component may also employ visual recognition to calculate the length of the gripping part based on the position of the end of the gripping part when the robotic arm 2 is in its initial state.

[0040] The present invention also provides an automatic assembly method for automotive parts, comprising the following steps: S1: The controller controls the feeding component 1 to transfer the workpiece 5 to the preset position. The controller controls the robotic arm 2 to move the clamping component 4 above the preset position so that the lowest clamping part is aligned with the workpiece 5 at the preset position. At this time, the robotic arm 2 is in the initial position. S2: The controller controls the robotic arm 2 to move the clamping part downward, so that the lowest clamping part is engaged in the back of the workpiece 5, and then the clamped workpiece 5 is lifted up; the feeding component 1 transmits the next workpiece 5 to the preset position, and the robotic arm 2 drives the clamping component 4 to rotate, so that the next clamping part is aligned with the workpiece 5 at the preset position. S3: Repeat step S2 until the number of inserts clamped on the clamping assembly 4 meets the number of inserts required for a single workpiece 5. S4: The controller controls the robotic arm 2 to transfer the clamped insert to the fixed workpiece 5. The robotic arm 2 adjusts the orientation of each clamping part according to the slot position of the workpiece 5, and inserts the insert into the slot one by one until the insertion of the insert into a single workpiece 5 is completed.

[0041] In step S1, the distance sensor first detects whether the workpiece 5 at the preset position has shifted. After the shift detection is completed, the controller controls the robotic arm 2 to move the clamping assembly 4 to the initial position. Then, the robotic arm 2 drives the clamping assembly 4 to rotate 360° to detect the shortest distance between the distance sensor and each clamping part.

[0042] In steps S1 and S2, whenever workpiece 5 is transferred to a preset position, a distance sensor detects whether workpiece 5 has been transferred to the preset position. If it has not been transferred to the preset position, the controller controls the feeding assembly 1 to continue transferring until workpiece 5 is transferred to the preset position. In step S4, after the insertion of the insert into a single workpiece 5 is completed, the controller controls the robotic arm 2 to adjust the position of the corresponding clamping part so that the clamping part is aligned with the corresponding central insertion hole 35. The robotic arm 2 pushes the clamping part laterally to push the workpiece 5 out of the positioning plate 31.

[0043] Using the above method, the clamping component 4 can clamp the insert required for a single workpiece 5 at a time. Each time the workpiece 5 is inserted, the robotic arm 2 only needs to make one round trip between the clamping position and the positioning component 3, which improves production efficiency. By setting the central insertion hole 35, after the robotic arm 2 completes the insertion of the insert for a single workpiece 5, it can adjust the position of the clamping part so that the single clamping part is aligned with one of the central insertion holes 35, pushing the protruding part of the workpiece 5 away from the central insertion hole 35, making it easier for the operator to remove the workpiece 5. By correcting the movement path through the correction component, the time for manual correction is saved, which improves production efficiency.

[0044] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
