Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts conveying technology, and more specifically, to a clamp positioning mechanism and a parts supply system. Background Technology
[0002] In automobile production, parts need to be transported from one workstation to the next, and then lifted to a certain height for robots to grasp and process. The existing solution is to use a jig with casters to load the parts. The jig moves to a set workstation along a ramped floor guide, lifting the parts to a certain height for the robot to grasp.
[0003] However, due to uneven ground and wear and tear on the casters of the gripper after prolonged use, the supply position of parts can deviate, causing parts to shift or even fall when the robot picks them up, ultimately affecting production efficiency and product consistency. Furthermore, moving the gripper loaded with parts along the ground guide rails to the designated workstation requires climbing a ramp, making transportation and propulsion difficult and resulting in wasted manpower. Summary of the Invention
[0004] In view of the problem in the prior art that wear of the clamping casters and unevenness of the ground can affect the positional accuracy of the parts after they are lifted, thus causing the robot to be unable to grasp the parts accurately, this utility model provides a clamping positioning mechanism and a feeding system, which can improve the positional accuracy of the parts after they are lifted, enabling the robot to grasp the parts accurately.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:
[0006] A clamp positioning mechanism is provided, comprising a support base, on which a left limiting frame, a right limiting frame, and a first lifting drive assembly are provided. The top of the left limiting frame has a left height limiting portion for abutting one side of the clamp, and the top of the right limiting frame has a right height limiting portion for abutting the other side of the clamp. An active cavity for the clamp to enter is formed between the left limiting frame and the right limiting frame. The first lifting drive assembly is located in the active cavity and is used to drive the clamp to rise to abut the left height limiting portion and the right height limiting portion, and to drive the clamp to descend and reset.
[0007] In the above technical solution, the positioning mechanism is set at a specific workstation. The fixture, loaded with automotive parts, moves from the previous workstation along the horizontal ground to the workstation where the positioning mechanism is located. During this process, the fixture first moves between the left and right limit frames. Then, the first lifting drive assembly lifts the fixture, causing both sides of the fixture to abut against the left and right height limit parts, respectively. The robot then picks up the parts from the fixture. Finally, the first lifting drive assembly lowers the fixture, returning it to the support base. The fixture then retracts from the support base and returns to the previous workstation to continue loading parts. By setting the left and right height limit parts to limit the height of the fixture after lifting, the parts on the fixture are fixed in a fixed position, avoiding positional errors caused by uneven ground and caster wear, thus improving the positional accuracy of the parts after being lifted.
[0008] Preferably, the left limiting frame has a left roller groove on the side near the right limiting frame, and the right limiting frame has a right roller groove on the side near the left limiting frame. Rollers are provided on both the left and right sides of the clamp. When the clamp enters the movable cavity between the left and right limiting frames, the rollers on the left and right sides of the clamp can roll along the left and right roller grooves respectively, thus ensuring a smooth movement of the clamp before it reaches its final position.
[0009] Preferably, the support base is further provided with a front limiting frame, which is located between one end of the left limiting frame and one end of the right limiting frame. A blocking block is provided on the side of the front limiting frame near the movable cavity. When the clamp moves to abut against the blocking block, it indicates that the clamp has moved into position. At this point, the clamp stops moving, and the first lifting drive assembly then drives the clamp to rise. The blocking block prevents the clamp from moving further forward when it is in position, ensuring that the clamp rises and falls in the accurate position.
[0010] Preferably, proximity sensors are provided at the top of both ends of the front limiting frame, the top of the inlet end of the left limiting frame, and the top of the inlet end of the right limiting frame. It is understood that the inlet end of the left limiting frame is the end furthest from the front limiting frame, and the inlet end of the right limiting frame is also the end furthest from the front limiting frame. When the gripper is raised to its correct position, the four proximity sensors are distributed at the four corners of the gripper, and each sensor can detect the presence of the gripper, thus confirming that the gripper has been raised to its correct position so that the robot can promptly grasp the parts on the gripper.
[0011] This utility model also provides a feeding system, which includes a clamp, the clamp including a material carrier with multiple casters, and the aforementioned clamp positioning mechanism; one side of the material carrier is provided with a left abutment for abutting against the left height limit, and the other side of the material carrier is provided with a right abutment for abutting against the right height limit. The cooperation process between the clamp and the clamp positioning mechanism has been described above, and therefore will not be repeated here.
[0012] Preferably, the left abutment portion is provided with a plurality of first rollers, the rotation axis of the first rollers being perpendicular to the material carrier, and the first rollers being used to extend into the left roller groove and abut against the inner wall of the left roller groove; the right abutment portion is provided with a plurality of second rollers, the rotation axis of the second rollers being perpendicular to the material carrier, and the second rollers being used to extend into the right roller groove and abut against the inner wall of the right roller groove. The first rollers and the second rollers can roll along the left roller groove and the right roller groove respectively, thereby keeping the material carrier stable during movement.
[0013] Preferably, the bottom of the material carrier is provided with an abutment block, the abutment block has a V-shaped protrusion, and the blocking block has a V-shaped groove for engaging with the V-shaped protrusion. The V-shaped structure has a guiding function; when the abutment block approaches the blocking block, the V-shaped protrusion will naturally slide into the V-shaped groove, automatically correcting even slight deviations and ensuring consistent abutment position each time. This ensures that the material carrier can rise and fall in the same position and with the same posture each time.
[0014] Preferably, the first lifting drive assembly includes multiple cylinders, and the bottom of the material carrier has multiple positioning grooves corresponding to each cylinder. These positioning grooves allow the piston rods of the cylinders to extend into and engage with the piston rods. After the material carrier moves into position, the cylinder extends its piston rod, causing its end to enter the positioning groove and abut against the bottom of the groove. It then continues to extend until the left and right abutment portions on the material carrier abut against the left and right height limit portions, respectively. Alternatively, the first lifting drive assembly can also be an electric actuator, a hydraulic cylinder drive assembly, a motor screw drive assembly, or a synchronous belt drive assembly. However, cylinders have a simpler structure, are easier to connect with fixtures, and operate more quickly.
[0015] Preferably, the support base is further provided with a rotary cylinder, the power output end of which is connected to a rotating component. The rotating component has a third roller, the rotation axis of which is parallel to the material carrier and perpendicular to the rotation axis of the rotary component. A clamping block is provided at the bottom of the material carrier. The rotary cylinder drives the rotating component to rotate, causing the third roller to abut against the side of the clamping block away from the front limiting frame. After the material carrier moves into position, the rotary cylinder drives the rotating component to rotate, causing the third roller on the rotating component to abut against one side of the clamping block. The first lifting drive assembly then drives the material carrier to rise. After the first lifting drive assembly drives the material carrier to descend and reset, the rotary cylinder drives the rotating component to rotate and reset, preventing the rotating component from interfering with the retraction of the material carrier. Using the third roller to abut against the clamping block makes the material carrier more stable during lifting and lowering, reducing the risk of the material carrier shifting or wobbling during lifting and lowering.
[0016] Preferably, a first support plate is connected to the top of the material carrier, the first support plate is provided with a positioning pin and an integrated power supply unit, and the contact sensors are all electrically connected to the integrated power supply unit; a bracket is provided on the front limiting frame, the top of the bracket is provided with a second lifting drive assembly, the power output end of the second lifting drive assembly is connected to the second support plate, the second support plate is provided with a positioning sleeve and a cable connector; the second lifting drive assembly is used to drive the second support plate to descend, so that the positioning pin extends into the positioning sleeve and the integrated power supply unit is electrically connected to the cable connector, and to drive the second support plate to rise and reset. The power line of the proximity sensor is integrated into the integrated power supply unit. After the first lifting drive assembly drives the material carrier to rise until the left and right abutment parts abut against the left and right height limiting parts respectively, the second lifting drive assembly drives the second support plate to descend, so that the positioning pin extends into the positioning sleeve, and at the same time the integrated power supply unit is connected to the cable connector and conducts electricity, thereby energizing the proximity sensor. After the proximity sensor is energized, it can detect whether the material carrier has reached its position. Understandably, if the proximity sensor is powered on prematurely, it may trigger false signals due to mechanical vibration, electromagnetic noise, or environmental interference (such as metal debris), leading to a misjudgment of "arrival". Powering on the proximity sensor after the material carrier has risen avoids this situation. The cooperation between the positioning pin and the positioning sleeve ensures precise alignment between the integrated power supply unit and the cable connector.
[0017] The beneficial effects of this utility model are:
[0018] (1) The fixture positioning mechanism is provided with a first lifting drive component, a left height limit part and a right height limit part. The first lifting drive component can lift the fixture when the fixture moves into place, so that the left abutting part and the right abutting part on the fixture abut against the left height limit part and the right height limit part on the fixture positioning mechanism respectively, thereby limiting the height of the fixture after lifting, thereby limiting the parts on the fixture to a fixed position, avoiding positional errors caused by uneven ground and wear of casters, and improving the positional accuracy of the parts after being lifted.
[0019] (2) A blocking block is provided on the support base of the fixture positioning mechanism, and an abutment block is provided on the material carrier of the fixture. When the fixture moves into position, the blocking block can cooperate with the abutment block to abut. A rotary cylinder and a third roller are also provided on the support base of the fixture positioning mechanism, and a clamping block is provided on the material carrier of the fixture. When the fixture moves into position, the rotary cylinder drives the third roller to clamp the clamping block. These settings can ensure that the fixture is raised and lowered in the same position with the same posture, thereby further improving the positional accuracy of the part after it is raised.
[0020] (3) A proximity sensor is set on the fixture positioning mechanism to sense the fixture, which can ensure that the fixture rises into place so that the robot can grab the part in time; moreover, the proximity sensor is powered on only after the fixture has moved into place, which can avoid the proximity sensor being powered on in advance and misjudging that it is "in place".

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0031] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0032] Example 1
[0033] This embodiment is a first embodiment of a clamp positioning mechanism, combined with Figures 1 to 4 As shown, it includes a support base 1, on which a left limiting frame 2, a right limiting frame 3, and a first lifting drive assembly 4 are provided. The top of the left limiting frame 2 is provided with a left height limiting part 201 for abutting one side of the clamp, and the top of the right limiting frame 3 is provided with a right height limiting part 301 for abutting the other side of the clamp. An active cavity for the clamp to enter is formed between the left limiting frame 2 and the right limiting frame 3. The first lifting drive assembly 4 is located in the active cavity and is used to drive the clamp to rise to abut against the left height limiting part 201 and the right height limiting part 301, and to drive the clamp to descend and reset.
[0034] Specifically, both the left height limit section 201 and the right height limit section 301 are rectangular small panels, and there are two of each.
[0035] Furthermore, the left limiting frame 2 has a left roller groove 202 on the side near the right limiting frame 3, and the right limiting frame 3 has a right roller groove 302 on the side near the left limiting frame 2. Rollers are provided on both the left and right sides of the clamp. When the clamp enters the movable cavity between the left limiting frame 2 and the right limiting frame 3, the rollers on the left and right sides of the clamp can roll along the left roller groove 202 and the right roller groove 302 respectively, thus ensuring a smooth movement of the clamp before it reaches its final position.
[0036] Furthermore, the support base 1 is also equipped with a front limiting frame 5, which is located between one end of the left limiting frame 2 and one end of the right limiting frame 3. A blocking block 6 is provided on the side of the front limiting frame 5 closest to the movable cavity. When the clamp moves to contact the blocking block 6, it indicates that the clamp has moved into position. At this point, the clamp stops moving, and the first lifting drive assembly 4 drives the clamp to rise. The blocking block 6 can prevent the clamp from continuing to move forward when it has moved into position, ensuring that the clamp rises and falls in the accurate position.
[0037] Furthermore, proximity sensors 7 are installed at the top of both ends of the front limiting frame 5, the top of the inlet end of the left limiting frame 2, and the top of the inlet end of the right limiting frame 3. It can be understood that the inlet end of the left limiting frame 2 is the end furthest from the front limiting frame 5, and the inlet end of the right limiting frame 3 is also the end furthest from the front limiting frame 5. When the gripper is raised to its correct position, the four proximity sensors 7 are distributed at the four corners of the gripper. Each proximity sensor 7 can detect the presence of the gripper, thus confirming that the gripper has been raised to its correct position, so that the robot can promptly grasp the parts on the gripper.
[0038] The working principle or workflow of this embodiment is as follows: The positioning mechanism is set up at a specific workstation. The fixture, loaded with automotive parts, moves from the previous workstation along the horizontal ground to the workstation where the positioning mechanism is located. During this process, the fixture first moves to abut against the blocking block 6 on the front limiting frame 5. Then, the first lifting drive assembly 4 drives the fixture to rise until the fixture abuts against the left height limit 201 and the right height limit 301 respectively. The robot then picks up the parts from the fixture. Finally, the first lifting drive assembly 4 lowers the fixture, causing it to return to the support base 1. The fixture then retracts from the support base 1 and returns to the previous workstation to continue loading parts.
[0039] The beneficial effects of this embodiment are as follows: The fixture positioning mechanism is provided with a first lifting drive component, a left height limit part and a right height limit part. When the fixture moves into place, the first lifting drive component can lift the fixture so that the left abutment part and the right abutment part on the fixture abut against the left height limit part and the right height limit part on the fixture positioning mechanism, respectively, thereby limiting the height of the fixture after it is lifted, thereby limiting the part on the fixture to a fixed position, avoiding positional errors caused by uneven ground and wear of casters, and improving the positional accuracy of the part after it is lifted.
[0040] Example 2
[0041] This embodiment is a first embodiment of a parts supply system, combined with Figures 1 to 6 As shown, it includes a clamp, which includes a material carrier 9 equipped with multiple casters 8, and also includes the clamp positioning mechanism described in Embodiment 1; one side of the bottom of the material carrier 9 is provided with a left abutment 901 for abutting against the left height limit 201, and the other side of the bottom of the material carrier 9 is provided with a right abutment 902 for abutting against the right height limit 301. Both the left abutment 901 and the right abutment 902 are elongated plates. When the first lifting drive assembly 4 drives the material carrier 9 to rise to a certain height, the left abutment 901 abuts against the left height limit 201, and the right abutment 902 abuts against the right height limit 301.
[0042] Furthermore, the left abutment portion 901 is provided with a plurality of first rollers 10, the rotation axis of the first rollers 10 being perpendicular to the material carrier 9, and the first rollers 10 can extend into the left roller groove 202 and abut against the inner wall of the left roller groove 202; the right abutment portion 902 is provided with a plurality of second rollers 11, the rotation axis of the second rollers 11 being perpendicular to the material carrier 9, and the second rollers 11 can extend into the right roller groove 302 and abut against the inner wall of the right roller groove 302. The first rollers 10 and the second rollers 11 can roll along the left roller groove 202 and the right roller groove 302 respectively, thereby keeping the material carrier 9 stable during movement.
[0043] Furthermore, the bottom front end of the material carrier 9 is provided with two abutment blocks 12, each abutment block 12 having a V-shaped protrusion 1201, and the blocking block 6 having a V-shaped groove 601 for engaging with the V-shaped protrusion 1201. The V-shaped structure has a guiding function; when the abutment block 12 approaches the blocking block 6, the V-shaped protrusion 1201 will naturally slide into the V-shaped groove 601, automatically correcting even slight deviations and ensuring consistent abutment position each time, thereby ensuring that the material carrier 9 can rise and fall in the same position and with the same posture each time.
[0044] Furthermore, the first lifting drive assembly 4 is provided with four cylinders, and the bottom of the material carrier 9 is provided with multiple positioning grooves (not shown in the figure) corresponding to the cylinders one by one. The positioning grooves are used for the piston rods of the cylinders to extend into and fit against the piston rods of the cylinders. After the material carrier 9 moves into position, the cylinder extends its piston rod, so that the end of the piston rod extends into the positioning groove and abuts against the bottom of the positioning groove, and then continues to extend until the left abutting part 901 and the right abutting part 902 on the material carrier 9 abut against the left height limiting part 201 and the right height limiting part 301, respectively.
[0045] Furthermore, the support base 1 is also equipped with a rotary cylinder 13. The power output end of the rotary cylinder 13 is connected to a rotating component 14. The rotating component 14 is equipped with a third roller 15. The rotation axis of the third roller 15 is parallel to the material carrier 9 and perpendicular to the rotation axis of the rotating component 14. The bottom of the material carrier 9 is equipped with a pressing block 16. The rotary cylinder 13 is used to drive the rotating component 14 to rotate, so that the third roller 15 abuts against the side of the pressing block 16 away from the front limit frame 5. After the material carrier 9 moves into position, the rotary cylinder 13 drives the rotating component 14 to rotate, so that the third roller 15 on the rotating component 14 abuts against one side of the pressing block 16, and the first lifting drive assembly 4 then drives the material carrier 9 to rise. After the first lifting drive assembly 4 drives the material carrier 9 to descend and reset, the rotary cylinder 13 drives the rotating component 14 to rotate and reset, avoiding interference from the rotating component 14 with the retraction of the material carrier 9. By using the third roller 15 to press against the clamping block 16, the material carrier 9 can be raised and lowered more smoothly, reducing the risk of the material carrier 9 shifting or shaking during the raising and lowering process.
[0046] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.
[0047] Example 3
[0048] This embodiment is a second embodiment of a component supply system. This embodiment is similar to embodiment 2, except that it combines... Figures 1 to 4 , Figure 7 As shown, the top of the material carrier 9 is connected to a first support plate 17. The first support plate 17 is provided with four positioning pins 18 and an integrated power supply unit 19. The contact sensors are all electrically connected to the integrated power supply unit 19. The front limit frame 5 is provided with a bracket 20. The top of the bracket 20 is provided with a second lifting drive assembly 21. The second lifting drive assembly 21 is a cylinder. Its power output end is connected to the second support plate 22. The second support plate 22 is provided with four positioning sleeves 23 and a cable connector 24. The second lifting drive assembly 21 is used to drive the second support plate 22 to descend, so that the positioning pins 18 extend into the positioning sleeves 23 and the integrated power supply unit 19 is electrically connected to the cable connector 24, and to drive the second support plate 22 to rise and reset. The power cord of the proximity sensor 7 is integrated into the integrated power supply unit 19. The first lifting drive assembly 4 drives the material carrier 9 to rise until the left abutment part 901 and the right abutment part 902 abut against the left height limit part 201 and the right height limit part 301, respectively. Then, the second lifting drive assembly 21 drives the second support plate 22 to descend, causing the positioning pins 18 to extend into the positioning sleeves 23 one by one. Simultaneously, the integrated power supply unit 19 connects and conducts with the cable connector 24, thereby energizing the proximity sensor 7. After the proximity sensor 7 is energized, it can detect whether the material carrier 9 is in position. It is understandable that if the proximity sensor 7 is energized prematurely, mechanical vibration, electromagnetic noise, or environmental interference such as metal debris may trigger false signals, leading to a false judgment of "in position." Energizing the proximity sensor 7 after the material carrier 9 has risen avoids this situation. The cooperation between the positioning pins 18 and the positioning sleeves 23 ensures precise docking between the integrated power supply unit 19 and the cable connector 24.
