Technical Field
[0001] This utility model belongs to the field of vacuum robotic arm suction cup technology, and in particular relates to a vacuum arm device for quick suction cup switching. Background Technology
[0002] Vacuum arm suction cup devices are a common material handling equipment widely used in various fields of industrial production. Their working principle is mainly to generate negative pressure through a vacuum generator, so that a pressure difference is formed between the suction cup and the surface of the object being adsorbed, thereby realizing the adsorption and handling of the object.
[0003] However, existing vacuum arm suction cup devices have obvious defects in the installation and fixing methods of the suction cups. At present, most vacuum arm suction cup devices use bolt installation and fixing methods. This method exposes many problems when the suction cup needs to be disassembled for maintenance and repair. Since multiple bolts need to be unscrewed one by one, the operation process is cumbersome and not only consumes a lot of time, but also makes the operation extremely difficult in some installation positions with limited space. It requires operators to have high operating skills and patience. In addition, frequent disassembly and installation of bolts can easily lead to stripped bolts, wear, or even damage to the installation parts of the equipment, increasing the maintenance cost and downtime of the equipment.
[0004] To address these issues, we provide a vacuum arm device with a quick-change suction cup. Utility Model Content
[0005] The purpose of this invention is to provide a vacuum arm device for quick-change of suction cups. By cooperating with the mounting components and connecting pipe components, it solves the problem that most vacuum arm suction cup devices in the prior art use bolt installation and fixing, which is extremely inconvenient when the suction cup needs to be disassembled for maintenance and repair.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a vacuum arm device for quick suction cup replacement, comprising a robotic arm, a mounting base at one end of the robotic arm, a mounting assembly at the bottom of the mounting base, a vacuum generator fixedly connected to one side of the top of the mounting assembly, a connecting pipe assembly on one side of the mounting assembly, and a mounting plate including a mounting plate whose top is fixedly connected to the bottom of the mounting base. Mounting grooves are formed on both sides of the bottom of the mounting plate, and a retaining seat is movably connected to the inner cavity of each mounting groove. A suction cup plate is fixedly connected to the bottom of the retaining seat. An intermediate groove is formed between the mounting grooves, and a fixing plate is fixedly connected to the bottom of the inner cavity of the intermediate groove. Return springs are fixedly connected to both sides of the fixing plate, and a beveled block is fixedly connected to one end of each return spring. A insert plate is fixedly connected to one side of each beveled block, and a trapezoidal seat is movably connected between the beveled blocks. A movable seat is fixedly connected to the top of the trapezoidal seat.
[0008] The present invention is further configured such that a limiting spring is fixedly connected to the top of the inner cavity of the mounting base, a movable plate is fixedly connected to the bottom of the limiting spring, the bottom of the movable plate is fixedly connected to the top of the movable base, and a buckle plate is provided on both the front and back of the movable plate, so that the movable plate moves downward and the movable base moves downward to a designated position. Then, the four buckle plates are rotated respectively, so that the buckle hole at one end of the buckle plate is fitted onto the protrusion on the surface of the mounting base, thereby limiting and fixing the movable base.
[0009] The present invention is further configured such that the connecting tube assembly includes a bent tube, one end of which is fixedly connected to one side of the vacuum generator, and the other end of which is connected to a corrugated tube. One end of the corrugated tube is fixedly connected to an installation tube. One side of the suction cup plate is fixedly connected to an insertion tube, and one side of the insertion tube is fixedly connected to a magnetic chuck. One side of the surface of the installation tube is fixedly connected to a connecting plate. The installation tube is moved until the plug at one end is inserted into the inner cavity of the insertion tube on one side of the suction cup plate until the magnetic chuck on the surface of the insertion tube is attracted to the connecting plate on the surface of the installation tube, thereby connecting the vacuum generator to the suction cup plate.
[0010] The present invention is further configured such that a column is provided on one side of the robotic arm, and a mounting plate is fixedly connected to the bottom of the column. The column with a rotating function supports the robotic arm, and the column can be installed at a designated work station.
[0011] The present invention is further configured such that limit rods are fixedly connected to the four corners of the top of the inner cavity of the mounting base, the limit rods are connected through the surface of the moving plate, and the four limit rods are respectively connected through the moving plate, making the moving plate more stable when it moves on the surface of the four limit rods.
[0012] The present invention is further provided that a handle is fixedly connected to the front of the movable plate, and the surface of the handle is provided with anti-slip texture, making it more convenient to pull the movable plate up and down by the handle.
[0013] The present invention is further configured such that an annular sleeve is fixedly connected to the bottom of the mounting plate, and an annular strip is fixedly connected to the top of the suction cup plate. When the suction cup plate is moved to the top of its card seat and inserted into the mounting groove at the bottom of the mounting plate, the annular strip at the top of the suction cup plate is inserted into the annular sleeve at the bottom of the mounting plate. The limiting structure composed of the annular strip and the annular sleeve improves the connection strength between the suction cup plate and the mounting plate.
[0014] The present invention is further configured such that a sealing ring is fixedly connected to the inner wall of the insertion tube, and the inner wall of the sealing ring is in close contact with the plug surface on one side of the installation tube.

[0015] The present invention has the following beneficial effects.
[0016] 1. This utility model has significant advantages in disassembly and maintenance. Compared with the tedious operation of unscrewing multiple bolts one by one in the traditional bolt installation method, it can disassemble the suction cup plate by rotating the buckle plate to disengage the buckle hole from the protrusion. With the help of the limit spring, the moving plate, moving seat and trapezoidal seat are moved upward, and the inclined block is moved out of the buckle seat by the action of the return spring. The suction cup plate can be disassembled without complicated tools and difficult operation, which greatly simplifies the disassembly process.
[0017] 2. This utility model can significantly reduce equipment maintenance costs and downtime. Traditional bolt installation is prone to bolt stripping, wear and damage to the equipment installation parts due to frequent disassembly. However, this device achieves quick installation through the cooperation of the insert plate and the card seat and the magnetic connection between the installation tube and the insert tube, avoiding the wear and tear caused by repeated bolt disassembly and reducing the equipment maintenance needs and downtime caused by component damage.

Detailed Implementation
[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1
[0028] Please see Figure 1-6 This utility model relates to a vacuum arm device for quick suction cup replacement, comprising a robotic arm 1, a mounting base 2 at one end of the robotic arm 1, a mounting assembly 3 at the bottom of the mounting base 2, a vacuum generator 4 fixedly connected to one side of the top of the mounting assembly 3, and a connecting pipe assembly 5 on one side of the mounting assembly 3. The mounting assembly 3 includes a mounting plate 301, the top of which is fixedly connected to the bottom of the mounting base 2. Mounting grooves 302 are provided on both sides of the bottom of the mounting plate 301, and the inner cavity of the mounting grooves 302 is movably connected to... Card holder 303, suction cup plate 304 is fixedly connected to the bottom of card holder 303, intermediate groove 305 is opened between mounting grooves 302, fixing plate 306 is fixedly connected to the bottom of the inner cavity of intermediate groove 305, reset spring 307 is fixedly connected to both sides of fixing plate 306, inclined block 308 is fixedly connected to one end of reset spring 307, insert plate 309 is fixedly connected to one side of inclined block 308, trapezoidal seat 310 is movably connected between inclined blocks 308, and movable seat 311 is fixedly connected to the top of trapezoidal seat 310.
[0029] Specifically: The suction cup plate 304 is moved until the top of the mounting plate 304 is inserted into the mounting groove 302 at the bottom of the mounting plate 301. The moving plate 7 is moved downward, which drives the moving seat 311 to move downward. The moving seat 311 drives the trapezoidal seat 310 to move downward. During the downward movement of the moving seat 311, the two inclined blocks 308 are squeezed, causing the two inclined blocks 308 to move to opposite sides. The inclined blocks 308 drive the insert plate 309 on one side to move and insert into the inner cavity of the mounting plate 303, thereby quickly installing the suction cup plate 304 at the bottom of the mounting plate 301.
[0030] Example 2
[0031] Please see Figure 1-6 Based on Embodiment 1, a limiting spring 6 is fixedly connected to the top of the inner cavity of the mounting base 2, and a movable plate 7 is fixedly connected to the bottom of the limiting spring 6. The bottom of the movable plate 7 is fixedly connected to the top of the movable base 311. Buckle plates 8 are provided on both the front and back of the movable plate 7. The connecting pipe assembly 5 includes a bent pipe 501, one end of which is fixedly connected to one side of the vacuum generator 4, and the other end of which is connected to a corrugated pipe 502. One end of the corrugated pipe 502 is fixedly connected to an mounting pipe 503. An insertion tube 504 is fixedly connected to one side of the suction cup plate 304, and a magnetic... A connecting plate 506 is fixedly connected to one side of the surface of the suction cup 505 and the mounting tube 503. A column 9 is set on one side of the robotic arm 1. The bottom of the column 9 is fixedly connected to the mounting plate. Limiting rods are fixedly connected to the four corners of the top of the inner cavity of the mounting base 2. The limiting rods are connected through the surface of the moving plate 7. A handle is fixedly connected to the front of the moving plate 7. The surface of the handle is provided with anti-slip texture. An annular sleeve is fixedly connected to the bottom of the mounting plate 301. An annular strip is fixedly connected to the top of the suction cup plate 304. A sealing ring is fixedly connected to the inner wall of the insertion tube 504. The inner wall of the sealing ring is in tight contact with the plug surface on one side of the mounting tube 503.
[0032] Specifically: The movable plate 7 moves downwards, causing the movable base 311 to move downwards to the designated position. Then, the four locking plates 8 are rotated so that the locking holes at one end of the locking plates 8 fit onto the protrusions on the surface of the mounting base 2, thus limiting and fixing the movable base 311. The mounting tube 503 is moved until its plug is inserted into the inner cavity of the insertion tube 504 on one side of the suction cup plate 304, until the magnetic suction cup 505 on the surface of the insertion tube 504 is attracted to the connecting plate 506 on the surface of the mounting tube 503, thus connecting the vacuum generator 4 to the suction cup plate 304. The rotating column 9 supports the robotic arm 1 and can be installed at a designated work position. The four limiting rods are respectively connected to the movable plate 7. The through-connection makes the movable plate 7 more stable when moving on the surface of the four limiting rods. It is also more convenient to pull the movable plate 7 up and down by the handle. When the suction cup plate 304 is moved to the top of its card seat 303 and inserted into the mounting groove 302 at the bottom of the mounting plate 301, the annular strip at the top of the suction cup plate 304 is inserted into the annular sleeve at the bottom of the mounting plate 301. The limiting structure composed of the annular strip and the annular sleeve improves the connection strength between the suction cup plate 304 and the mounting plate 301. When the mounting tube 503 is moved to the end of its plug and inserted into the inner cavity of the insertion tube 504, the sealing ring of the inner cavity of the insertion tube 504 wraps around the surface of the mounting tube 503. The sealing ring improves the connection sealing between the mounting tube 503 and the insertion tube 504.
[0033] The working principle of this utility model is as follows: When the suction cup plate 304 needs to be replaced, firstly, pull one end of the mounting tube 503 out of the inner cavity of the insertion tube 504. Then, rotate the four buckle plates 8 until the buckle hole on one side disengages from the protrusion on the surface of the mounting base 2. The moving plate 7 moves upward under the action of the limiting spring 6. The moving plate 7 drives the moving base 311 and its bottom trapezoidal base 310 to move upward. The two inclined blocks 308 move relative to each other under the action of the return spring 307, thereby driving the insertion plate 309 on one side to move out of the inner cavity of the buckle base 303. Then, the suction cup plate 304 can be moved downward for disassembly. After the suction cup plate 304 is repaired or replaced with a new suction cup plate 304, move the suction cup plate 304 until the buckle base 303 at its top is inserted into the mounting plate 30. In the mounting slot 302 at the bottom, the moving plate 7 moves downward, which in turn moves the moving seat 311 downward. The moving seat 311 then moves the trapezoidal seat 310 downward. During the downward movement of the moving seat 311, the two inclined blocks 308 are squeezed, causing them to move to opposite sides. The inclined blocks 308 move the insert plate 309 on one side of them and insert it into the inner cavity of the card holder 303, thereby quickly installing the suction cup plate 304 at the bottom of the mounting plate 301. Finally, the mounting tube 503 is moved until the plug at one end is inserted into the inner cavity of the insert tube 504 on one side of the suction cup plate 304, until the magnetic suction cup 505 on the surface of the insert tube 504 is attracted to the connecting plate 506 on the surface of the mounting tube 503, thereby connecting the vacuum generator 4 to the suction cup plate 304.
