Description

Technical Field

[0001] This invention relates to the field of assembly station technology, and more particularly to a parking number plate assembly station. Background Technology

[0002] Currently, cars have become commonplace in households. With the increasing number of cars, parking difficulties have become a major problem for many car owners. When encountering an emergency and parking haphazardly, if the car blocks other vehicles, people often leave a note with their phone number on the windshield to facilitate contact for others to move the car or make emergency calls. However, such notes are inconvenient to preserve, as they need to be rewritten the next time the car is parked. Therefore, people use paper temporary parking signs with their phone numbers written on them. However, paper temporary parking signs also cannot be preserved indefinitely.

[0003] Therefore, based on the above issues, a more advanced parking number plate is available. The numbers on the parking number plate are laser-engraved, allowing for long-term preservation. In addition to the basic number display function, this plate also incorporates a fragrance-emitting stick. This plate is shown in the instruction manual. Figure 1 As shown, the structure includes a column, a spice stick, a base, and end caps at both ends of the column. Currently, when assembling this number plate, workers use handheld nailing machines in an assembly line operation. First, one end cap is installed on the column, then the spice stick is placed inside the column, then the other end cap is installed, and finally the base is installed. However, this assembly method requires a lot of manpower, which greatly increases labor costs. At the same time, the efficiency and quality of assembly vary from person to person and cannot be guaranteed, making continuous and efficient assembly work impossible.

[0004] Therefore, there is an urgent need for an assembly station that can replace manual labor in assembling license plates, in order to reduce labor costs and achieve efficient assembly. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a parking number plate assembly station. The above-mentioned technical objective of this invention is achieved through the following technical solution:

[0036] The present invention will now be clearly and completely described in conjunction with embodiments.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0038] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] See appendix Figure 1-10The diagram shows a parking number plate assembly station, including a chassis 1, a robotic arm 2, a material placement unit 3, a horizontal nailing unit 5, a vertical nailing unit 6, a first clamping unit 7, a second clamping unit 8, and a nail supply unit 9. Specifically, a multi-axis robotic arm 2 is fixed to the chassis 1 by bolts. The robotic arm 2 has a connector installed at its execution end, and the robotic arm 2 is quickly connected to the quick-change fixture 49 through the connector to perform various assembly processes of the parking number plate. The chassis 1 has a nail supply unit 9 and a carrying rack 10 on both sides of the robotic arm 2. The carrying rack 10 has a material placement unit 3. The nail supply unit 9 is specifically a hopper with a vibrating plate. The hopper contains screws, and the vibrating plate feeds the screws into the module in an orderly manner. Its internal structure and working principle are existing mature technologies and will not be described in detail here.

[0040] The material placement unit 3 includes a tray 11, which can slide horizontally on the carrier 10. Two limiting posts 12 are vertically provided on the tray 11. A material tray 13 is placed on the tray 11. The material tray 13 has limiting holes that match the limiting posts 12. When the material tray 13 is placed on the tray 11, the limiting posts 12 and the limiting holes cooperate to lock the material tray 13, preventing the material tray 13 from shifting randomly and affecting the precise gripping of the robot arm 2. One end of the material tray 13 is provided with a support post 15 for placing the base 61. The other end of the material tray 13 is provided with a material insertion bucket 16 for placing the spice stick 60.

Opposite to the material insertion bucket 16, there is a material dispensing box 18 for placing the first plug 58 and the second plug 59.

[0041] A base frame 4 is provided at the end of the chassis 1 away from the nail supply unit 9. A first clamping unit 7 and a second clamping unit 8 are arranged side by side on the base frame 4. The first clamping unit 7 is provided with a first support 19. A first clamping cylinder 20 is provided inside the first support 19. The first clamping cylinder 20 is provided with two telescopic ends that move in opposite directions. First grippers 21 are symmetrically provided on the telescopic ends. A first arc-shaped clamping opening 22 is provided on the first grippers 21. The first clamping cylinder 20 drives the two symmetrical first grippers 21 to effectively clamp and fix the column 57 using the first arc-shaped clamping opening 22.

[0042] The second clamping unit 8 is provided with a second support 23, and a second clamping cylinder 24 is provided inside the second support 23. The second clamping cylinder 24 is provided with two telescopic ends that move in opposite directions. The telescopic ends are symmetrically provided with second grippers 25. The second grippers 25 are provided with a second arc-shaped clamping opening 26. The second grippers 25 are provided with a right-angle notch 27 at the top of the second arc-shaped clamping opening 26. The four right-angle notches 27 on the two second grippers 25 can form a receiving cavity that is the same as that of the base 61. When gripping the base 61, the base 61 is exactly located in the four right-angle notches 27 to complete the clamping of the base 61.

[0043] The first clamping cylinder 20 and the second clamping cylinder 24 are specifically a wide-type pneumatic gripper;

[0044] A horizontal nailing unit 5 is provided on the chassis 1 perpendicular to the clamping direction of the first clamping unit 7. The horizontal nailing unit 5 has a base plate 28, and a guide rail 29 is provided on the base plate 28. A first slider 30 is slidably mounted on the guide rail 29. A nail gun 32 is mounted on the first slider 30, and the nail gun 32 has a bit 33. A second slider 31 is slidably mounted on the guide rail 29 in the feed direction of the bit 33. The second slider 31 has a clamping mouth 34 for cooperating with the bit 33 to nail. The clamping mouth 34 has a nail inlet 35, which is connected to the nail supply unit 9 through a pipe. A push plate 36 is provided at the end of the first slider 30 away from the second slider 31. A first elastic device 37 is provided between the push plate 36 and the second slider 31. A second elastic device 38 is provided between the first slider 30 and the second slider 31. A tapping drive cylinder 39 is provided on the other side of the push plate 36, opposite to the first elastic device 37. A fixed seat is provided at one end of the base plate 28 away from the second slider 31. A displacement drive cylinder 40 is provided on the fixed seat. The telescopic end of the displacement drive cylinder 40 is connected to the nail gun 32. A fixed plate 41 is provided vertically on the other side of the base plate 28. Two fixing holes are provided on the fixed plate 41. The entire horizontal nailing unit is fixedly connected to the chassis 1 through the fixed plate 41 and the fixing holes. The center of the first arc-shaped clamp 22 is collinear with the bit 33 of the nail gun 32. When nailing, the displacement drive cylinder 40 drives the nail gun 32 to move a wide range on the guide rail 29. For example, the nail gun 32 is first moved to a position close to the first clamping unit 7. Then, the tapping drive cylinder 39 is used to nail precisely. When nailing, the first elastic device 37 and the second elastic device 38 are used to ensure the stability of the entire nailing and play a buffering role. The specific nailing process is the existing technology and has also been described in the invention patent CN 114952260 A.

[0045] The first elastic device 37 and the second elastic device 38 are specifically a gas spring;

[0046] The chassis 1 is provided with a support unit on one side of the base frame 4. The support unit is provided with a support column 42 vertically. The top of the support column 42 is provided with an overlap plate 43. The overlap plate 43 is provided with two first positioning columns 44. The jig frame 45 is provided with a clamping block 46. The clamping block 46 is provided with a V-shaped placement opening 47. The V-shaped placement opening 47 is provided with two second positioning columns 48.

[0047] A quick-change clamp 49 is placed inside the V-shaped placement opening 47 via the second positioning post 48. The quick-change clamp 49 is an isosceles triangle. A first clamp 50 and a second clamp 51 are respectively provided on the two sides of the quick-change clamp 49. The first clamp 50 is provided with a first V-shaped clamping opening 52, which is used to clamp the spice stick 60. The second clamp 51 is provided with a second V-shaped clamping opening 53, which is used to clamp the column 57, the first plug 58, and the second plug 59. The second clamp 51 is provided with a rectangular clamping opening 54 at the top of the second V-shaped clamping opening 53, which is used to clamp and grasp the base 61.

[0048] A vertical nailing unit 6 is overlapped on the overlapping plate 43. The horizontal nailing unit 5 and the vertical nailing unit 6 have the same structure. The vertical nailing unit 6 is positioned and fixed with the first positioning post 44 through the fixing hole on the fixing plate 41.

[0049] In order to achieve quick connection between the robot arm 2 and the vertical nailing unit 6, a quick connector that matches the connector head of the robot arm 2's execution end is also provided on the fixing plate 41 of the vertical nailing unit 6. The specific structure of the quick connector is completely consistent with the quick connector on the quick-change fixture 49.

[0050] To improve the clamping accuracy and continuity of the first clamping unit 7 and the second clamping unit 8, a first pair of photoelectric switches 55 are provided on both sides of the first clamping unit 7. When the first plug 58 and the second plug 59 are installed on the column 57, a signal can be fed back to activate the horizontal nailing unit 5 to nail when there is an object between the first pair of photoelectric switches 55. A second pair of photoelectric switches 56 are provided on both sides of the second clamping unit 8. The second pair of photoelectric switches 56 sense whether there is a base 61 on the column 57. When a base 61 is sensed to be placed on the column 57, the vertical nailing unit 6 is activated to nail vertically.

[0051] In order to ensure that the base 61 can be accurately placed in the corresponding position of the column 57 and accurately driven into the nail, a positioning pin 14 is provided between the two first jaws 21 and the second jaw 25. The positioning pin 14 achieves accurate positioning with the positioning hole on the column 57.

[0052] As shown in Figures 11-13, during the assembly of parking number plates, the robotic arm 2 first connects quickly to the quick-change fixture 49 via the connector at the actuator end. Then, the robotic arm 2 drives the quick-change fixture 49 to grip the column 57 on the tray 13 using the second V-shaped jaw 53. After gripping, the column 57 is placed in the first arc-shaped jaw 22 of the first gripper 21. Next, the first clamping cylinder 20 clamps and fixes it in place. Then, the second V-shaped jaw 53 grips the first plug 58 and places it at the end of the column 57 near the clamping nozzle 34. At this time, the first through-beam switch 55 senses the... The presence of a plug 58 feeds a signal back to the main control PLC. The main control starts the horizontal nailing unit 5 to nail the first plug 58 to the column 57. Then, the first clamping cylinder 20 is released, and the robot arm 2 uses the second V-shaped clamp 53 to rotate the column 57 180 degrees, turning the end of the column 57 with the first plug 58 to the other end. Then, the robot arm 2 uses the first V-shaped clamp 52 to grab the spice stick 60 on the material tray 13 and put it into the column 57. Then, it uses the second V-shaped clamp 53 to grab the second plug 59 and place it at the front end of the clamp 34 to nail it.

[0053] Next, the column 57, which is equipped with the first plug 58 and the second plug 59, is placed in the second gripper 25 of the second clamping unit 8 and clamped and fixed. Then, the robot arm 2 uses the rectangular jaw 54 on the second gripper 51 to grab the base 61 on the tray 13 and place it in the corresponding position on the column 57. At this time, the second through-beam switch 56 senses the presence of the base 61 and also feeds the signal back to the main control PLC. Then, the robot arm 2 connects to the vertical nailing unit 6 through the execution end and performs vertical nailing on the base 61, thus completing the entire assembly task.

[0054] The entire assembly process is fully automated, completely replacing manual labor, reducing labor costs, and improving assembly efficiency and quality.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
