Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and more specifically, to a positioning device for modular assembly of industrial robots. Background Technology

[0002] Industrial robots are widely used in modern industrial production. Their modular design facilitates production, maintenance and upgrading. In the modular assembly process of industrial robots, accurate positioning is the key to ensuring robot performance and precision.

[0003] Existing positioning devices are often limited by their structure, and can only be used to position and fix workpieces of the same type of industrial robot, lacking versatility and reducing work efficiency.

[0004] A search revealed that Chinese patent CN216299097U discloses a positioning device for an industrial robot production line. This structure can flexibly adapt to the fixing requirements of industrial robot workpieces of different specifications. It uses a first electric telescopic rod to push a connecting rod, which drives a slider to move along the first slide rod. This allows the U-shaped support plate to adjust the spacing of the lower arc-shaped clamping plates, thereby adapting to the positioning and fixing of workpieces of different lengths, improving versatility and work efficiency. At the same time, with the help of the lower arc-shaped clamping plate, the upper arc-shaped clamping plate, the second slide rod, the second electric telescopic rod, and the spring, the second electric telescopic rod can push the upper arc-shaped clamping plate down along the second slide rod to achieve clamping of workpieces of different thicknesses, further enhancing adaptability. When the upper arc-shaped clamping plate moves down and contacts the lower arc-shaped clamping plate with the workpiece, the spring is compressed to buffer the impact force and avoid damage to the upper arc-shaped clamping plate or the workpiece due to excessive contact force.

[0005] However, in actual use, this structure adjusts the spacing by pushing the slider along the slide bar with the first electric telescopic rod. This relies on the stroke control of the electric telescopic rod, which results in accuracy deviations due to mechanical backlash. Furthermore, it can only be adjusted in a single direction, limiting its adaptability to the width of irregular shapes. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular assembly positioning device for industrial robots to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A modular assembly and positioning device for industrial robots includes a base plate, a support frame fixedly mounted on the top of the base plate, two movable blocks slidably mounted inside the support frame, and an adjustment mechanism mounted on one side of each movable block.

[0009] The adjustment mechanism includes a movable frame fixedly disposed on one side of the movable block, a movable strip slidably disposed inside the movable frame, a guide groove being formed on the surface of the movable frame, a protrusion being fixedly disposed on one side of the movable strip, a plurality of threaded holes being formed on the surface of the movable frame, and a threaded groove being formed on the surface of the movable strip.

[0010] A rubber layer is fixedly provided on one side of both the moving frame and the moving bar, and a stabilizing frame is fixedly provided at the bottom of the moving bar. A ball wheel is rotatably provided inside the stabilizing frame.

[0011] The protrusion is slidably connected inside the guide groove, and the threaded hole and the threaded groove are locked together by bolts.

[0012] By adopting the above technical solution, it can flexibly adapt to modules of different widths, improving versatility. The rubber layer avoids rigid contact to protect the module, and the ball wheel reduces friction to make adjustment smoother. Overall, it enhances the adaptability, protection and ease of operation of the device.

[0013] As a further description of the above technical solution: the top of the movable frame is provided with an auxiliary mechanism, the auxiliary mechanism includes a plurality of electric telescopic rods fixedly installed on the top of the movable frame, the output end of the electric telescopic rods is fixedly provided with a fixing plate, the cross-section of the fixing plate is L-shaped, and the surface of the fixing plate is fixedly provided with a silicone layer.

[0014] A stepper motor is fixedly installed on one side of the support frame, and a bidirectional threaded rod is fixedly provided at the output end of the stepper motor. The bidirectional threaded rod is threadedly connected to the movable block.

[0015] By adopting the above technical solution, the horizontal spacing of the moving frame can be precisely adjusted to adapt to modules of different lengths. Secondly, vertical fixation can be achieved. The two work together to form a three-dimensional and stable clamping. Furthermore, the silicone layer protects the module from damage. Automated adjustment reduces the intensity of manual operation and improves the versatility, fixation reliability and assembly efficiency of the device.

[0016] As a further description of the above technical solution: the surface of the movable block is provided with a through hole, and a roller is rotatably provided on the inner wall of the through hole;

[0017] An anti-slip layer is fixedly installed on one side of both the base plate and the support frame. The anti-slip layer can be made of wear-resistant rubber.

[0018] By adopting the above technical solution, the roller inside the through hole of the moving frame can reduce friction when the module moves, making it easier to fine-tune the module position. Moreover, the anti-slip layer of wear-resistant rubber material enhances the friction between the base plate and the support frame and the contact surface, preventing the device from sliding as a whole, and improving the operational flexibility and overall stability.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. By setting an adjustment mechanism, compared with the existing technology, the protrusion and guide groove work together to drive the moving strip to flexibly adjust the extension length, which can accurately adapt to modules of different widths to be assembled, greatly improving the versatility of the device. Moreover, the ball wheels in the stabilizing frame reduce friction during movement, making the moving strip slide more smoothly, reducing operating resistance and saving adjustment time. Secondly, the bolt passing through the threaded hole and threaded groove for locking can quickly fix the adjusted position and ensure clamping stability. At the same time, the rubber layer on one side of the moving frame and the moving strip avoids rigid contact with the module, effectively preventing surface scratches and protecting the module's precision. In addition, the overall structure is simple and efficient, which not only enhances the device's adaptability to modules of different specifications, but also ensures ease of operation and module safety.

[0021] 2. By setting up an auxiliary mechanism, compared with existing technologies, the L-shaped fixing plate driven by the electric telescopic rod can flexibly adjust its height to adapt to modules with different top heights, achieving precise vertical fixing and preventing the modules from shifting up and down during assembly, thus ensuring assembly accuracy. Secondly, the silicone layer makes flexible contact with the top of the module, which not only enhances friction to prevent slippage but also avoids rigid compression that could damage the module, protecting the integrity of the components. In addition, the horizontal fixing driven by the stepper motor and the bidirectional threaded rod forms a three-dimensional clamping system, which keeps the module stable during bolt connections, wiring connections, and other operations, reducing assembly errors. At the same time, the automated drive of the electric telescopic rod reduces the intensity of manual fixing, improves the convenience of operation, and improves the overall stability, safety, and efficiency of the assembly process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The embodiments disclosed in this application are as follows: Figure 1-5 The illustrated modular assembly and positioning device for industrial robots includes a base plate 1, a support frame 2 fixedly mounted on the top of the base plate 1, two movable blocks 3 slidably mounted inside the support frame 2, and an adjustment mechanism mounted on one side of each movable block 3.

[0030] The adjustment mechanism includes a movable frame 4 fixedly mounted on one side of the movable block 3, a movable strip 5 slidably mounted inside the movable frame 4, a guide groove on the surface of the movable frame 4, a protrusion 6 fixedly mounted on one side of the movable strip 5, multiple threaded holes 7 on the surface of the movable frame 4, and a threaded groove on the surface of the movable strip 5.

[0031] A rubber layer 8 is fixedly provided on one side of both the movable frame 4 and the movable bar 5, and a stabilizing frame 9 is fixedly provided at the bottom of the movable bar 5. A ball wheel 10 is rotatably provided inside the stabilizing frame 9.

[0032] The protrusion 6 is slidably connected inside the guide groove, and the threaded hole 7 is locked to the threaded groove by bolts.

[0033] According to the width of the module to be assembled, the protrusion 6 slides in the guide groove on the surface of the moving frame 4, which drives the moving strip 5 to move inside the moving frame 4, changing the length of the moving strip 5 extending out of the moving frame 4. When the moving strip 5 moves, the ball wheel 10 inside the stabilizing frame 9 rotates, which facilitates the movement of the moving strip 5 and makes its movement smoother.

[0034] Once the moving strip 5 reaches the appropriate position, the bolt is passed through the threaded hole 7 on the surface of the moving frame 4 and screwed into the threaded groove on the surface of the moving strip 5 to lock and fix the moving frame 4 and the moving strip 5. At this time, the rubber layer 8 on one side of the moving frame 4 and the moving strip 5 can avoid direct rigid contact with the module surface to prevent scratches.

[0035] Reference Figure 2-4 As shown, an auxiliary mechanism is provided on the top of the movable frame 4. The auxiliary mechanism includes multiple electric telescopic rods 11 fixedly installed on the top of the movable frame 4. A fixing plate 12 is fixedly installed on the output end of the electric telescopic rod 11. The cross-section of the fixing plate 12 is L-shaped. A silicone layer 13 is fixedly installed on the surface of the fixing plate 12.

[0036] A stepper motor 14 is fixedly installed on one side of the support frame 2. A bidirectional threaded rod 15 is fixedly provided at the output end of the stepper motor 14. The bidirectional threaded rod 15 is threadedly connected to the movable block 3.

[0037] The modular components of the industrial robot are placed between two movable frames 4, with one side attached to the anti-slip layer 18 on one side of the support frame 2. Then, the stepper motor 14 fixedly installed on one side of the support frame 2 is started. The output end of the stepper motor 14 drives the bidirectional threaded rod 15 to rotate. Since the bidirectional threaded rod 15 is threadedly connected to the movable block 3, it will drive the two movable blocks 3 to slide relative to each other or towards each other in the horizontal direction inside the support frame 2.

[0038] Next, the multiple electric telescopic rods 11 at the top of the moving frame 4 are activated. The output end of the electric telescopic rods 11 pushes the fixing plate 12 downward. Since the cross-section of the fixing plate 12 is L-shaped, the position of the fixing plate 12 can be adjusted according to the top height of the module, so that the silicone layer 13 on the surface of the fixing plate 12 is close to the top surface of the module, achieving vertical fixation and ensuring that the module will not shift during assembly.

[0039] Reference Figure 4-5 As shown, the surface of the movable block 3 is provided with a through hole 16, and a roller 17 is rotatably provided on the inner wall of the through hole 16;

[0040] An anti-slip layer 18 is fixedly installed on one side of both the base plate 1 and the support frame 2. The anti-slip layer 18 can be made of wear-resistant rubber material.

[0041] Furthermore, the roller 17 inside the through hole 16 on the surface of the moving frame 4 can reduce the friction between the module and the moving frame 4 when the module is pushed, making it easier for the module to move to the precise position. This allows the distance between the two moving frames 4 to be adjusted to accommodate the length of the module to be assembled, until both ends of the module make initial contact with the rubber layer 8 of the moving frame 4, so that the moving frame 4 and the moving strip 5 clamp the module from both sides, completing the precise horizontal positioning.

[0042] Working principle of this utility model:

[0043] This utility model is a modular assembly positioning device for industrial robots. When in use, the device is placed on a horizontal workbench to ensure that the anti-slip layer 18 on one side of the base plate 1 is in close contact with the table surface. The wear-resistant rubber anti-slip layer 18 enhances the overall stability of the device and prevents displacement during the assembly process.

[0044] Next, the modular components of the industrial robot are placed between the two movable frames 4, with one side attached to the anti-slip layer 18 on one side of the support frame 2. Then, the stepper motor 14 fixedly installed on one side of the support frame 2 is started. The output end of the stepper motor 14 drives the bidirectional threaded rod 15 to rotate. Since the bidirectional threaded rod 15 is threadedly connected to the movable block 3, it will drive the two movable blocks 3 to slide relative to or towards each other in the horizontal direction inside the support frame 2.

[0045] Furthermore, the roller 17 inside the through hole 16 on the surface of the moving frame 4 can reduce the friction between the module and the moving frame 4 when the module is pushed, making it easier for the module to move to the precise position. This allows the distance between the two moving frames 4 to be adjusted to accommodate the length of the module to be assembled, until both ends of the module make initial contact with the rubber layer 8 of the moving frame 4, so that the moving frame 4 and the moving strip 5 clamp the module from both sides, completing the precise horizontal positioning.

[0046] Then, according to the width of the module to be assembled, the protrusion 6 slides in the guide groove on the surface of the moving frame 4, driving the moving strip 5 to move inside the moving frame 4, changing the length of the moving strip 5 extending out of the moving frame 4. When the moving strip 5 moves, the ball wheel 10 inside the stabilizing frame 9 rotates, which facilitates the movement of the moving strip 5 and makes its movement smoother.

[0047] When the moving bar 5 reaches the appropriate position, the bolt is passed through the threaded hole 7 on the surface of the moving frame 4 and screwed into the threaded groove on the surface of the moving bar 5 to lock and fix the moving frame 4 and the moving bar 5. At this time, the rubber layer 8 on one side of the moving frame 4 and the moving bar 5 can avoid direct rigid contact with the module surface to prevent scratches.

[0048] Next, the multiple electric telescopic rods 11 at the top of the moving frame 4 are activated. The output end of the electric telescopic rods 11 pushes the fixing plate 12 downward. Since the cross-section of the fixing plate 12 is L-shaped, the position of the fixing plate 12 can be adjusted according to the top height of the module, so that the silicone layer 13 on the surface of the fixing plate 12 is close to the top surface of the module, achieving vertical fixation and ensuring that the module will not shift during assembly.

[0049] After the module is stably fixed, the assembly of the industrial robot module is carried out, such as bolt connection and wiring connection.

[0050] 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.
