Description

Technical Field

[0001] This application relates to the technical field of automated conveying of automotive parts, and in particular to a high-stability pedal support workpiece conveying device. Background Technology

[0002] In the fields of machinery manufacturing and automobile production, automated conveying systems have become a core means of improving production efficiency and reducing labor costs. With the deepening implementation of the Industry 4.0 concept, enterprises' requirements for the level of automation in production lines continue to rise. In the automobile manufacturing process, the stability and precision of the conveying process of the pedal support, as a key component affecting the overall vehicle assembly quality and production rhythm, are particularly important.

[0003] Currently, the industry commonly uses conveyor belts, robotic arms, or pneumatic conveying devices for automated workpiece transport. However, these existing technologies have many limitations when applied to pedal support transport scenarios: conveyor belt transport is prone to subsequent assembly deviations due to insufficient workpiece positioning accuracy; robotic arms are less adaptable to complex working conditions and are prone to unstable gripping during high-speed transport. Utility Model Content

[0004] In view of the above-mentioned prior art, in order to solve the problem of unstable gripping by the robot during high-speed transport, this application provides a high-stability pedal support workpiece conveying device.

[0005] This application provides a high-stability pedal support workpiece conveying device, which adopts the following technical solution: A high-stability pedal support workpiece conveying device includes a conveying component, a positioning component, and a gripping component mounted on a robotic arm. The positioning component is disposed at one end of the conveying component, and the workpiece is conveyed to the positioning component through the conveying component. The gripping component is fixedly mounted on the robotic arm. The gripping component includes a bracket, a mounting block, and a connecting tube. The bracket is fixedly mounted on the robotic arm, the mounting block is fixedly mounted on the bracket, one end of the connecting tube is fixedly connected to the mounting block, and the end of the connecting tube away from the connecting tube is a fitting end for fitting the workpiece. A magnetic block for adsorbing the workpiece is installed inside the connecting tube.

[0006] By adopting the above technical solution, the conveying component realizes automated workpiece conveying, the positioning component accurately positions the workpiece at the end of the conveyed process, and the gripping component achieves stable gripping of the workpiece through a combination of mechanical fitting and magnetic adsorption. Specifically, the fitting end of the connecting tube provides initial mechanical restraint for the workpiece, and the magnetic block further enhances gripping stability through magnetic force. This effectively solves the problem of unstable gripping that easily occurs in traditional robotic arms during high-speed conveying, and improves the anti-interference capability during workpiece conveying.

[0007] Preferably, a first driving cylinder is mounted on the mounting block, and a connecting hole communicating with a connecting pipe is provided on the mounting block. The output end of the first driving cylinder passes through the connecting hole and is located inside the connecting pipe. A pin is provided at the output end of the first driving cylinder, and a through hole for the pin to pass through is provided on the magnetic block.

[0008] By adopting the above technical solution, stable release of the workpiece is achieved through the cooperation of the first drive cylinder and the ejector pin. When the workpiece needs to be placed to the next station, the first drive cylinder drives the ejector pin through the through hole of the magnetic block and pushes the workpiece, causing the workpiece to overcome the attraction force of the magnetic block and detach from the connecting tube, avoiding poor workpiece release or positional displacement due to residual magnetic force. The precise cooperation between the ejector pin and the through hole of the magnetic block ensures the reliability of the release action and achieves seamless connection between gripping and releasing.

[0009] Preferably, the conveying assembly includes a conveyor belt and a guide member. A support frame is provided at the bottom of the conveyor belt. The support frame includes a first vertical frame and a second vertical frame. The first vertical frame and the second vertical frame are respectively provided at both ends of the conveyor belt along its length. The first vertical frame is higher than the second vertical frame. The conveyor belt is inclined. The positioning component is located at the lower end of the conveyor belt. The guide member is provided on the conveyor belt.

[0010] By adopting the above technical solution, the inclined conveyor belt can utilize gravity to assist in workpiece transport, reducing power consumption while improving transport efficiency. The first and second vertical supports of the support frame form a height difference, ensuring the conveyor belt maintains a stable inclination angle, allowing the workpiece to slide naturally in a predetermined direction. The positioning component is located at the lower end of the conveyor belt, facilitating the smooth entry of the workpiece into the positioning area under gravity and reducing the risk of transport stalls.

[0011] Preferably, the guide member consists of two guide rods, which are located on both sides of the conveyor belt and are arranged along the length of the conveyor belt.

[0012] By adopting the above technical solution, the guide rods on both sides of the conveyor belt provide lateral constraints on the workpiece during the conveying process, preventing the workpiece from shifting left or right or flipping on the conveyor belt. The guide rods are set along the length of the conveyor belt, ensuring that the workpiece always moves along the centerline of the conveyor belt, providing a stable initial posture for subsequent positioning processes and reducing positioning adjustment errors.

[0013] Preferably, the positioning component includes a positioning plate and a positioning block. The positioning plate is mounted on the second vertical frame, and the positioning block is fixedly mounted on the top surface of the positioning plate. The positioning block has a positioning groove, the contour of which matches the workpiece.

[0014] By adopting the above technical solution, the positioning groove on the positioning block accurately positions the workpiece through contour matching. When the workpiece is conveyed to the positioning assembly, the positioning groove restricts the workpiece's six degrees of freedom, ensuring that the workpiece is in a uniform reference position before being gripped, thus solving the problem of insufficient positioning accuracy in traditional conveyor belt conveying. The positioning plate provides a stable mounting foundation for the positioning block, ensuring that the positional accuracy of the positioning groove remains stable over a long period of time.

[0015] Preferably, one end of each of the two guide rods is located on both sides of the positioning block. The positioning assembly also includes a second drive cylinder, which is fixedly mounted on the second vertical frame. The bottom surface of the positioning plate is fixedly connected to the output end of the second drive cylinder.

[0016] By adopting the above technical solution, the guide rod extends to both sides of the positioning block, continuing to provide guidance after the workpiece leaves the conveyor belt, accurately guiding the workpiece into the positioning groove and preventing the workpiece from drifting due to loss of support. The second drive cylinder can drive the positioning plate and positioning block to rise and fall vertically. During the gripping phase, the lifting action moves the workpiece away from the guide rod, forming a safe operating distance in the vertical direction, preventing the gripping components from colliding with the guide rod, and improving the safety of equipment operation.

[0017] Preferably, the positioning block is equipped with a photoelectric sensor for detecting whether the workpiece has reached the predetermined position.

[0018] By adopting the above technical solution, the photoelectric sensor enables automatic detection of workpiece positioning. When the workpiece enters the positioning slot and reaches the predetermined position, the photoelectric sensor sends a signal to the control system, triggering subsequent gripping actions. This design achieves automated linkage between conveying, positioning, and gripping processes, reducing manual intervention and improving the coordination and response speed of the production line.

[0019] Preferably, the top surface of the positioning plate is provided with a fixing block, and the fixing block has a fixing hole, and the photoelectric sensor is fixedly installed in the fixing hole.

[0020] By adopting the above technical solution, the fixing block and fixing hole provide a precise installation position for the photoelectric sensor, ensuring that the sensor's detection direction corresponds to the workpiece position in the positioning groove, thereby improving detection accuracy. The fixed installation method avoids positional displacement of the photoelectric sensor due to vibration or impact, ensuring detection stability during long-term use and reducing false triggering or missed detections.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The automated conveying component enables the conveying of workpieces, the positioning component precisely positions the workpieces at the end of the conveying process, and the gripping component achieves stable gripping of workpieces through a combination of mechanical attachment and magnetic adsorption. The attachment end of the connecting tube can provide initial mechanical restraint for the workpiece, and the magnetic block further enhances the gripping stability through magnetic force. This effectively solves the problem of unstable gripping that is prone to occur in traditional robotic arms during high-speed conveying and improves the anti-interference ability during the workpiece conveying process. 2. With the triple guarantee of continuous guidance by the guide rod, contour matching of the positioning groove, and position detection by the photoelectric sensor, the workpiece positioning accuracy is significantly improved, providing a reliable benchmark for subsequent assembly processes and effectively reducing assembly deviations; 3. The stable release of the workpiece is achieved through the cooperation of the first drive cylinder and the ejector pin. When the workpiece needs to be placed to the next station, the first drive cylinder drives the ejector pin to pass through the through hole of the magnetic block and push the workpiece, so that the workpiece overcomes the attraction force of the magnetic block and detaches from the connecting tube, avoiding poor workpiece release or position displacement due to residual magnetic force. The precise cooperation between the ejector pin and the through hole of the magnetic block ensures the reliability of the release action and achieves seamless connection between gripping and release.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a high-stability pedal support workpiece conveying device.

[0026] Reference Figure 1 and Figure 2 A high-stability pedal support workpiece conveying device includes a conveying component 1, a positioning component 2, and a gripping component 3. The positioning component 2 is located at one end of the conveying component 1, and the gripping component 3 is fixedly mounted on a robot arm. The workpiece is conveyed to the positioning component 2 for positioning through the conveying component 1, and the robot arm drives the gripping component 3 to grip the workpiece and convey it to the next external assembly station.

[0027] Specifically, the conveying assembly 1 includes a conveyor belt 11 and a guide member 12. A support frame 4 is fixedly installed at the bottom of the conveyor belt 11. The support frame 4 includes a first vertical frame 41 and a second vertical frame 42, which are respectively fixedly connected to both ends of the conveyor belt 11, with the first vertical frame 41 being higher than the second vertical frame 42. The conveyor belt 11 is inclined by the first vertical frame 41 and the second vertical frame 42, and the positioning assembly 2 is located at the end of the conveyor belt 11 near the second vertical frame 42. The guide member 12 consists of two guide rods 121, which are located on both sides of the conveyor belt 11 and are arranged along the length of the conveyor belt 11.

[0028] Reference Figure 1 and Figure 3 The positioning component 2 includes a positioning plate 21 and a positioning block 22. The positioning plate 21 is located at one end of the conveyor belt 11 near the second vertical frame 42. The positioning block 22 is fixedly installed on the top surface of the positioning plate 21. The positioning block 22 has a positioning groove 221 that matches the workpiece. A fixing block 5 is provided on one side of the positioning block 22. The fixing block 5 has a fixing hole 51. A photoelectric sensor 6 for detecting whether the workpiece has reached the predetermined position is fixedly installed in the fixing hole 51.

[0029] Two guide rods 121 extend from one end of the conveyor belt 11 near the second vertical frame 42, and the ends of the two guide rods 121 extending from the conveyor belt 11 are respectively located on both sides of the positioning block 22. When the workpiece leaves the conveyor belt 11, it can avoid posture flipping, skewing or position drifting due to loss of constraint. Instead, under continuous guiding action, it is accurately guided and entered into the positioning groove 221 on the positioning block 22, thereby significantly improving the success rate and repeatability of the positioning operation.

[0030] The positioning component 2 also includes a second drive cylinder 23, which is fixedly installed on the side of the second vertical frame 42 opposite to the first vertical frame 41, and the output end of the second drive cylinder 23 reciprocates along the vertical direction of the second vertical frame 42. The side of the positioning plate 21 opposite to the positioning block 22 is fixedly connected to the output end of the second drive cylinder 23. When the gripping component 3 on the robotic arm performs the gripping action, there is a potential possibility of collision with the guide rod 121. Through the lifting action of the second drive cylinder 23, a safe operating distance is formed in the vertical direction, so that the gripping operation can be completed in an unobstructed independent space.

[0031] Reference Figure 4 and Figure 5 Specifically, the gripping component 3 includes a bracket 31, a mounting block 32, and a connecting pipe 33. The bracket 31 is fixedly mounted on the actuator end of the robot arm. The mounting block 32 is fixedly mounted on the side of the bracket 31 away from the robot arm by bolts. One end of the connecting pipe 33 is fixedly connected to the side of the mounting block 32 away from the bracket 31, and the axial direction of the connecting pipe 33 is perpendicular to the conveying direction of the conveyor belt 11. The end of the connecting pipe 33 away from the mounting block 32 is the fitting end for fitting the workpiece, and its inner diameter is slightly larger than the outer diameter of the corresponding part of the workpiece, which can achieve preliminary positioning of the workpiece. A magnetic block 7 for adsorbing the workpiece is fixedly installed inside the connecting pipe 33 near the fitting end. The magnetic block 7 has a ring structure and is tightly attached to the inner wall of the connecting pipe 33, which adsorbs the workpiece by magnetic force to enhance gripping stability.

[0032] The gripping component 3 also includes a first driving cylinder 34, which is fixedly installed on the side of the mounting block 32 away from the connecting pipe 33. The mounting block 32 has a connecting hole 321 that communicates with the connecting pipe 33. The output end of the first driving cylinder 34 passes through the connecting hole 321 and is located inside the connecting pipe 33. A pin 8 is fixedly installed on the output end of the first driving cylinder 34. A through hole 71 for the pin 8 to pass through is opened on the magnetic block 7.

[0033] When gripping a workpiece, the robotic arm drives the gripping component 3 to move to one side of the positioning component 2. At this time, the second drive cylinder 23 has driven the positioning plate 21 and positioning block 22 to rise into position according to the signal from the photoelectric sensor 6, so that the workpiece in the positioning groove 221 is at a safe gripping height. Under the drive of the robotic arm, the connecting tube 33 approaches the workpiece along the axial direction, and the sleeve end gradually fits into the corresponding part of the workpiece. The matching of the inner diameter of the connecting tube 33 and the outer diameter of the workpiece achieves preliminary mechanical limiting. At this time, the annular magnetic block 7 in the connecting tube 33 contacts or approaches the workpiece, and the magnetic force generates an adsorption force to firmly fix the workpiece in the sleeve end, avoiding the workpiece from falling off or shifting due to the inertia generated by the movement, vibration or high-speed conveying of the robotic arm during the gripping process.

[0034] After the gripping action is completed, the robot arm drives the gripping assembly 3 and the workpiece to disengage from the positioning slot 221. At this time, the first drive cylinder 34 retracts, and the end of the ejector pin 8 is located in the through hole 71 of the magnetic block 7, without interfering with the workpiece, ensuring that the workpiece is stably held in the gripping state until it is transported to the next station. Subsequently, the robot arm drives the gripping assembly 3 to move to the predetermined release position of the next station, ensuring that the workpiece is aligned with the assembly reference of the next station. At this time, the first drive cylinder 34 is activated, and its output end pushes the ejector pin 8 to extend along the axis of the connecting tube 33. After the ejector pin 8 passes through the through hole 71 of the magnetic block 7, it contacts the workpiece and continuously applies a pushing force. As the ejector pin 8 extends, the workpiece overcomes the attraction force of the magnetic block 7, gradually detaches from the sleeve end of the connecting tube 33, and is stably placed in the designated position of the next station. After the workpiece is completely released, the first drive cylinder 34 drives the ejector pin 8 to retract and reset, and the end of the ejector pin 8 retracts into the through hole 71 of the magnetic block 7 or into the connecting tube 33. The robot arm then drives the gripping assembly 3 to leave, ready to perform the next gripping action.

[0035] The implementation principle of this embodiment is as follows: The inclined conveyor belt 11, combined with gravity, assists in the transport of the workpiece. The guide rods 121 on both sides continuously constrain the workpiece, ensuring stable movement along a predetermined path. When the workpiece detaches from the conveyor belt 11, the guide rods 121 extending to both sides of the positioning block 22 continue to guide, accurately guiding the workpiece into the positioning groove 221, achieving initial positioning. The second drive cylinder 23 of the positioning component 2 is activated based on the detection signal from the photoelectric sensor 6, driving the positioning plate 21 and positioning block 22 to rise, preventing interference between the gripping component 3 and the guide rods 121. The gripping component 3 achieves initial positioning through the mechanical matching of the connecting tube 33 with the workpiece, while the magnetic attraction of the annular magnetic block 7 enhances gripping stability. This dual constraint effectively prevents the workpiece from falling off or shifting during high-speed transport. When transported to the next station, the first drive cylinder 34 drives the ejector pin 8 to extend, overcoming magnetic force to smoothly release the workpiece, completing the entire transport process.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
