Description

Technical Field

[0001] This utility model relates to the technical field of power line transfer devices, and more specifically, to a tray structure and a power line carrier. Background Technology

[0002] In the fields of modern automated production and intelligent warehousing and logistics, power line carriers are the core equipment for realizing continuous material transportation. Their load-bearing stability, positioning accuracy and transportation efficiency directly affect the operational efficiency of the production line.

[0003] Chinese patent document (publication number: CN219468781U) discloses a conveying device for an assembly line, including a driven component, a frame disposed above the driven component, and a loading device disposed on the frame. The driven component comprises a pulley assembly connected below the frame, a connecting block connected below the pulley assembly, and a drive block rotatably connected to the connecting block. A drive rail is provided below the drive block, and the drive rail has protrusions. When the drive block abuts against the protrusions, the drive rail drives the driven component forward. This invention allows for smooth material flow, improves material conveying and storage efficiency, and maximizes the storage of materials in limited space.

[0004] This conveying device discloses a carrier whose structure includes a connecting frame with a cavitary carrier body mounted on the connecting frame. The cavitary carrier is used to transport product components. This cavity-type carrier has a relatively high overall height, which makes its stability during operation relatively poor. When components are offset within the cavitary carrier, the carrier is prone to tipping over during track changes. Secondly, this carrier is fixed using clamps to hold the cavitary carrier body for easy gripping and handling by robotic arms during assembly line movement. However, the robotic arms require a certain amount of time to reach the positioning holes when gripping and handling the cavitary carrier body, which can easily lead to collisions. Therefore, this conveying device requires a relatively slow operating speed of the power line, which affects the conveying efficiency of the components. Utility Model Content

[0005] The problem solved by this utility model is to provide a tray structure and a power line carrier for a power line carrier, which improves the stability of items on the carrier and the transmission rate.

[0006] To solve the above problems, the present invention adopts the following technical solution: The pallet structure of the power line carrier includes: a pallet body, a snap-fit ​​guide wall and at least two connectors. The pallet body has a receiving platform for supporting items. The snap-fit ​​guide wall is connected to the pallet body so that when the items are placed on the receiving platform, the snap-fit ​​guide wall guides and snaps the items. The connectors are located on both sides of the receiving platform, and the density of the connectors is greater than the density of the receiving platform. The connectors are used to support the receiving platform.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: First, when the robotic arm grips or places an item onto the receiving platform, the guide wall guides the item, correcting any placement deviations by eliminating the need for repeated adjustments and saving placement time. Second, the guide wall and the side wall of the item form a flexible interlock, limiting horizontal displacement and preventing rigid collisions. Third, the connectors located on both sides of the receiving platform and having a higher density than the platform itself lower the overall center of gravity of the pallet structure, reducing inertial swaying. Furthermore, the high-density connectors have higher compressive strength than traditional support structures, stably bearing the weight of the item and preventing support deformation.

[0008] Furthermore, the snap-fit ​​guide wall includes: a first sidewall and a second sidewall respectively disposed on both sides of the receiving platform, the first sidewall and the second sidewall being bent relative to the receiving platform so that when the item is placed on the receiving platform, the first sidewall and the second sidewall form a guide snap-fit ​​for the item.

[0009] Compared with existing technologies, the technical effects achieved by this solution are as follows: First, the double-sided bending structure expands the guiding range of the snap-fit ​​guide wall, which not only reduces the collision between the item and the pallet structure due to the robot arm's misalignment, but also reduces the time for the robot arm to place the item on the receiving platform, thus improving placement efficiency. Second, the first and second side walls form a symmetrical snap-fit ​​with the item, which not only increases the contact area between the item and the snap-fit ​​guide wall, but also makes the item more evenly constrained by the snap-fit ​​wall.

[0010] Furthermore, the first sidewall and / or the second sidewall are made of an elastic material, or the first sidewall and / or the second sidewall are provided with a cushioning structure so that the sidewall forms an adaptive clamping when it comes into contact with the item.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: when the robotic arm grips the special box and places it on the receiving platform, the box first contacts the inclined surface of the elastic sidewall. The elastic sidewall is squeezed by the box and undergoes adaptive deformation, which neither hinders the box from sliding down, but also conforms to the contour of the box sidewall through deformation. At the same time, the inclined angle of the elastic sidewall continues the guiding function, guiding the box to slide accurately to the positioning area of ​​the receiving platform.

[0012] Furthermore, the included angle between the first sidewall and the second sidewall satisfies 90° < a < 180°.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: a guide channel that is wider at the top and narrower at the bottom is formed between the first and second side walls, with the top opening being wider than the width of the item, making it easier to initially place the item; the bottom angle is narrowed to match the width of the item, guiding the item to slide smoothly down the inclined side wall, avoiding edge obstruction, and clamping the item.

[0014] Furthermore, the connector is provided with a mounting groove, the tray body is embedded in the mounting groove, and the outer wall of the tray body is flush with the outer wall of the mounting groove. The outer wall of the mounting groove causes the receiving platform of the tray body to extend horizontally to increase the receiving area of ​​the receiving platform.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: First, the bottom of the pallet body is embedded entirely into the mounting groove, and circumferential and radial positioning is achieved through the positioning structure on the inner wall of the mounting groove. It is then fixed by bolt connection or welding, making the pallet body and the connecting body an integrated structure. Second, the depth of the mounting groove is consistent with the thickness of the bottom of the pallet body, ensuring that after the pallet body is installed, the bottom surface of its top receiving platform is flush with the top of the connecting body. The extended area and the original receiving platform are an integrated structure, ensuring that materials can be stably supported in the extended area as well. This not only increases the bearing area, but the center of gravity adjustment effect of the counterweight structure can balance the center of gravity shift caused by the offset of large-sized materials, ensuring the overall stability of the pallet.

[0016] Furthermore, positioning parts are provided on both sides of the connector. These positioning parts are used to cooperate with the items to restrict the degree of freedom of the items on the tray body.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: by using a positioning unit to position the items, it can prevent the items from shaking relative to the pallet or other parts of the power line carrier during the transportation process, and reduce the risk of collision when the robot places the items.

[0018] Furthermore, the positioning part is provided with a positioning hole and the tray body is provided with an abutment notch, and the positioning hole and the abutment notch are engaged.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: when the pallet body is embedded in the mounting groove, the positioning hole presses against the notch, and the notch elastically deforms to allow the positioning hole to be inserted; after the pallet body is in place, the positioning hole and the notch form a snap-fit ​​lock.

[0020] Furthermore, the positioning hole is provided with a snap-fit ​​boss and an abutment wall. The snap-fit ​​boss protrudes towards the center of the positioning hole and is used to snap and engage with the item.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: When an item is inserted into the positioning hole, the side wall of the item presses against the locking protrusion. Due to the elasticity of the material, the protrusion undergoes slight deformation, allowing the item to be inserted smoothly. The contact surface of the abutment wall directly abuts against the bottom surface of the item, limiting the radial displacement of the item along the positioning hole through rigid contact. After the item is fully inserted, the locking protrusion springs back to its original position, and its protruding part is embedded in the pre-set annular groove on the side wall of the item or abuts against the side wall of the item, forming an axial limit to prevent the item from moving axially. This ensures that the side wall of the item always maintains a tight fit with the abutment wall, avoiding the loss of radial limit function due to axial displacement. At the same time, the axial fixing effect of the locking protrusion means that the abutment wall only needs to bear the radial limit task and does not need to bear additional axial force, reducing the stress burden on the abutment wall and reducing the risk of wear or deformation due to excessive force.

[0022] This utility model also provides a power line carrier, including the tray structure of any of the above. The power line carrier includes: a drive mechanism, a drive interface, and a fixing part in the middle of the connecting body. The fixing part is fixed to the drive interface, and the drive mechanism is used to drive the tray structure to move.

[0023] Compared with existing technologies, the technical effects achieved by this solution are as follows: First, the fixing part is embedded in the drive interface, pre-positioned by the positioning pin slot, and then locked and fixed by bolts, buckles, etc.; the drive mechanism is used to drive the movement of the entire device. Second, the centrally located fixing part can align the support center of the connecting body with the center of gravity of the tray body, avoiding tray tilting caused by support point misalignment.

[0024] Furthermore, the drive mechanism includes a main drive component and a slave drive component, each with a drive interface; the tray body has bolt holes that mate with the drive interfaces to fix the tray body, connector, and drive mechanism.

[0025] Compared with existing technologies, the technical effects achieved by this solution are as follows: First, the drive mechanism includes a main drive component and a driven component, both with drive interfaces. Compared to the traditional single-drive component design, when the power line carrier is carrying materials, the main drive component outputs the main power, while the driven component provides auxiliary power. Their collaboration helps to distribute the load, preventing overload damage to a single drive component due to long-term heavy loads. Second, the bolt holes on the pallet body mate with the drive interfaces to secure the pallet body, connecting body, and drive mechanism. Compared to the traditional method of only securing the connecting body and drive mechanism, the bolt holes and drive interfaces eliminate relative displacement between the three components, preventing loosening due to long-term vibration and ensuring stable power transmission from the drive mechanism to the pallet structure, reducing power loss due to loosening. Simultaneously, the rigid fixation of the three components forms an integrated structure, dispersing stress generated during operation, preventing component deformation caused by localized stress concentration, and extending the service life of the entire device. Furthermore, the bolted connection facilitates later disassembly and maintenance; when a component is damaged, it can be quickly replaced by removing the bolts, reducing maintenance difficulty and cost.

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] See Figures 1-5The pallet structure of the power line carrier includes: a pallet body 1, a snap-fit ​​guide wall 6, and at least two connectors 10. The pallet body 1 has a receiving platform 2 for supporting items. The snap-fit ​​guide wall 6 is connected to the pallet body 1 so that when items are placed on the receiving platform 2, the snap-fit ​​guide wall 6 guides and snaps the items. The connectors 10 are located on both sides of the receiving platform 2, and the density of the connectors 10 is greater than the density of the receiving platform 2. The connectors 10 are used to support the receiving platform 2.

[0030] Firstly, when the robotic arm grips or places an item onto the receiving platform 2, the guide wall 6 guides the item, correcting any placement deviations by eliminating the need for repeated adjustments and saving placement time. Secondly, the guide wall and the side wall of the item form a flexible interlock, limiting horizontal displacement of the item while preventing rigid collisions. Thirdly, the connecting bodies 10 are located on both sides of the receiving platform 2 and have a higher density than the platform itself. By placing the connecting bodies 10 on both sides, the overall center of gravity of the pallet structure is lowered, reducing inertial swaying. At the same time, the high-density connecting bodies 10 have higher compressive strength than traditional support structures, allowing them to stably bear the weight of the item and preventing support deformation.

[0031] Specifically, see Figure 1 and Figure 2 The snap-fit ​​guide wall 6 includes a first side wall 3 and a second side wall 4 respectively disposed on both sides of the receiving platform 2. The first side wall 3 and the second side wall 4 are bent relative to the receiving platform 2 so that when the item is placed on the receiving platform 2, the first side wall 3 and the second side wall 4 form a guide snap-fit ​​for the item.

[0032] For example, when the robotic arm grips or places an item onto the receiving platform 2, the item uses a special box with an abutment structure in the middle. The first side wall 3 and the second side wall 4 form a snap-fit ​​structure with the special box of the item and guide the item, thus shortening the placement time of the item on the receiving platform 2.

[0033] Firstly, the double-sided bending structure expands the guiding range of the snap-fit ​​guide wall 6, which not only reduces the collision between the item and the pallet structure due to the robot arm's misalignment, but also reduces the time it takes for the robot arm to place the item on the receiving platform 2, thus improving placement efficiency. Secondly, the first side wall 3 and the second side wall 4 form a symmetrical snap-fit ​​with the item, which not only increases the contact area between the item and the snap-fit ​​guide wall 6, but also makes the item more evenly constrained by the snap-fit ​​wall.

[0034] Specifically, the first sidewall 3 and / or the second sidewall 4 are made of an elastic material, or the first sidewall 3 and / or the second sidewall 4 are provided with a buffer structure so that the sidewalls form an adaptive clamping when they come into contact with the item.

[0035] For example, the elastic material can be spring steel sheets, and the side that contacts the special box body of the item has a smooth curved surface design.

[0036] When the robotic arm grips the special box and places it onto the receiving platform 2, the box first contacts the inclined surface of the elastic sidewall. The elastic sidewall is squeezed by the box and undergoes adaptive deformation, which neither hinders the box from sliding down, but also conforms to the contour of the box sidewall through deformation. At the same time, the inclined angle of the elastic sidewall continues the guiding function, guiding the box to slide into the positioning area of ​​the receiving platform 2.

[0037] Specifically, the included angle between the first sidewall 3 and the second sidewall 4 satisfies 90° < a < 180°.

[0038] A guide channel, wider at the top and narrower at the bottom, is formed between the first sidewall 3 and the second sidewall 4. The top opening is wider than the width of the item, making it easy to initially place the item in. The bottom angle is narrowed to match the width of the item, guiding the item to slide smoothly down the inclined sidewall, avoiding edge obstruction, and clamping the item.

[0039] Specifically, see Figure 3 and Figure 4 The connector 10 is provided with a mounting groove 11, the tray body 1 is embedded in the mounting groove 11, and the outer wall of the tray body 1 is flush with the outer wall of the mounting groove 11. The outer wall of the mounting groove 11 causes the receiving platform 2 of the tray body 1 to extend horizontally to increase the receiving area of ​​the receiving platform 2.

[0040] Firstly, the bottom of the pallet body 1 is embedded entirely into the mounting groove 11. The circumferential and radial positioning is achieved through the positioning structure on the inner wall of the mounting groove 11, and then it is fixed by bolt connection or welding, so that the pallet body 1 and the connecting body 10 form an integrated structure. Secondly, the depth of the mounting groove 11 is consistent with the thickness of the bottom of the pallet body 1, ensuring that after the pallet body 1 is installed, the bottom surface of its top receiving platform 2 is flush with the top of the connecting body 10. The extended area and the original receiving platform 2 are an integrated structure, ensuring that the materials can be stably supported in the extended area. This not only increases the bearing area, but the center of gravity adjustment effect of the counterweight structure can balance the center of gravity shift caused by the offset of large-sized materials, ensuring the overall stability of the pallet.

[0041] Specifically, see Figure 3 and Figure 4 The connecting body 10 has positioning parts on both sides. The positioning parts are used to cooperate with the items to restrict the degree of freedom of the items on the tray body 1.

[0042] Using a positioning unit to position items can prevent items from swaying relative to the pallet or other parts of the power line carrier during transportation, reducing the risk of collision when the robot places items.

[0043] Specifically, see Figure 3 and Figure 4 The positioning part is provided with positioning hole 5, and the tray body 1 is provided with abutment notch 12. The positioning hole 5 and the abutment notch 12 are engaged.

[0044] For example, the item uses a special box with positioning posts on it, and the diameters of the positioning posts and positioning holes 5 are matched.

[0045] When the tray body 1 is installed in the mounting groove 11, the positioning hole 5 presses against the notch 12, and the notch 12 elastically deforms to allow the positioning hole 5 to be inserted; after the tray body 1 is in place, the positioning hole 5 and the notch 12 form a snap-fit ​​locking engagement.

[0046] Specifically, the positioning hole 5 is provided with a snap-fit ​​boss 8 and an abutment wall 9. The snap-fit ​​boss 8 protrudes towards the center of the positioning hole 5 and is used to snap-fit ​​with the item.

[0047] For example, the snap-fit ​​boss 8 is a protruding structure integrally formed or welded to the inner wall of the positioning hole 5. The width of the protrusion is 1 / 5 to 1 / 4 of the inner diameter of the positioning hole 5, and it is evenly distributed along the circumference of the inner wall of the positioning hole 5. For example, 3-4 bosses are arranged in a ring array. The snap-fit ​​boss 8 protrudes towards the center of the positioning hole 5. The distance between the snap-fit ​​boss 8 and the entrance end of the positioning hole 5 is not less than the effective depth of the positioning post inserted into the positioning hole 5. The surface of the snap-fit ​​boss 8 can be rounded to avoid scratching the items.

[0048] To reiterate, the abutment wall 9 is a rigid annular structure integrally formed on the inner wall of the positioning hole 5. It is made of the same or higher strength material as the positioning hole 5 body and extends circumferentially along the inner wall of the positioning hole 5. The height of the abutment wall 9, i.e. the radial protrusion dimension of the abutment wall 9, is determined according to the design gap between the positioning post and the positioning hole 5 to ensure that the gap between the positioning post and the positioning hole 5 can be filled. The abutment walls 9 are evenly distributed in the positioning hole 5, and 2-4 can be arranged circumferentially and 1-2 sections can be arranged axially.

[0049] When an item is inserted into the positioning hole 5, the side wall of the item presses against the locking boss 8. Due to the elasticity of the material, the boss undergoes a slight deformation, allowing the item to be inserted smoothly. The contact surface of the abutment wall 9 directly abuts against the bottom surface of the item, restricting the radial displacement of the item along the positioning hole 5 through rigid contact. After the item is fully inserted, the locking boss 8 springs back to its original position, and its protruding part is embedded in the pre-set annular groove on the side wall of the item or abuts against the side wall of the item, forming an axial limit to prevent the item from moving axially. This ensures that the side wall of the item always remains in close contact with the abutment wall 9, avoiding the loss of radial limit function due to axial displacement. At the same time, the axial fixing effect of the locking boss 8 means that the abutment wall 9 only needs to bear the radial limit task and does not need to bear additional axial force, reducing the stress burden on the abutment wall 9 and reducing the risk of wear or deformation due to excessive force.

[0050] See Figure 1 This utility model also provides a power line carrier, including the tray structure of any one of the above, the power line carrier including: The drive mechanism 13 is provided with a drive interface 14, and the connecting body 10 has a fixing part 15 in the middle. The fixing part 15 is fixed to the drive interface 14. The drive mechanism 13 is used to drive the pallet structure to move.

[0051] First, the fixing part 15 is embedded in the drive interface 14, and is pre-positioned by the positioning pin slot, and then locked and fixed by bolts, buckles and other means; the drive mechanism 13 is used to drive the movement of the entire device. Second, the fixing part 15 is centrally located so that the support center of the connecting body 10 is aligned with the center of gravity of the tray body 1, avoiding tray tilting caused by the offset of the support point.

[0052] Specifically, see Figure 5 The drive mechanism 13 includes a main drive component 16 and a slave drive component 17, and the main drive component 16 and the slave drive component 17 are respectively provided with drive interfaces 14; the tray body 1 is provided with bolt holes 18, which cooperate with the drive interfaces 14 to fix the tray body 1, the connecting body 10 and the drive mechanism 13.

[0053] Firstly, the drive mechanism 13 includes a main drive component 16 and a driven component 17, both of which are equipped with drive interfaces 14. Compared with the traditional single drive component design, when the power line carrier is carrying materials, the main drive component 16 outputs the main power, and the driven component 17 provides auxiliary power output. The two work together to share the load and avoid the single drive component from being overloaded and damaged due to long-term heavy load. Secondly, the bolt holes 18 of the tray body 1 cooperate with the drive interface 14 to fix the tray body 1, the connecting body 10, and the drive mechanism 13. Compared with the traditional method of fixing only the connecting body 10 and the drive mechanism 13, the cooperation between the bolt holes 18 and the drive interface 14 can eliminate the relative displacement between the three, avoid loosening of the connection caused by long-term vibration, ensure that the power is stably transmitted from the drive mechanism 13 to the tray structure, and reduce the power loss caused by loosening. At the same time, the rigid fixation of the three forms an integrated structure, which can disperse the stress generated during operation and avoid component deformation caused by local stress concentration (such as bending of the connecting body 10 and deformation of the tray body 1), thus extending the service life of the entire device. Moreover, the bolt connection method facilitates disassembly and maintenance in the later stage. When a component is damaged, it can be quickly replaced by removing the bolts, reducing the difficulty and cost of maintenance.
