Description

Technical Field

[0001] The utility model relates to the field of industrial loading tools, and particularly relates to a positioning carrier. Background Art

[0002] In the automatic assembly process of sheet products, at present, the transportation of sheet products between various stations on the equipment mostly adopts a profiling positioning carrier or a bilateral elastic and complex positioning method. To meet the automatic assembly of this sheet product, a set of jigs with high positioning accuracy and stability needs to be developed to meet the transmission of each workstation.

[0003] Chinese Patent No. CN204843918U discloses a profiling positioning carrier mechanism, which roughly positions the outer shape through the outer shape of the product. After the outer shape positioning is completed, the moving cylinder drives the positioning module to move through the moving guide rod, and combines with the needle-shaped protrusions on the upper part of the positioning module to accurately position the product. When the processing or detection of the product is completed, the moving cylinder drives the positioning module to move to both sides through the moving guide rod, releases the needle-shaped protrusions on the upper part of the positioning module, and then the product can be taken out. However, the above profiling positioning carrier mechanism adopts complex components such as a moving cylinder, a moving guide rod, a positioning module and needle-shaped protrusions, and its structure is relatively complex, which may increase the manufacturing cost and maintenance difficulty. Moreover, during the positioning process of the profiling positioning carrier mechanism, the moving cylinder needs to drive the positioning module to move through the moving guide rod, and combines with the needle-shaped protrusions on the upper part of the positioning module for accurate positioning, which involves the coordinated movement of multiple components and is troublesome to control. In addition, although the profiling positioning carrier mechanism realizes the accurate positioning of the product through the needle-shaped protrusions, its positioning accuracy may be affected by multiple factors, such as the thrust stability of the cylinder and the guiding accuracy of the guide rod, and cannot meet the high-precision requirements for positioning carriers nowadays.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. The structure of this case is simple and easy to implement. Through the mutual cooperation of the longitudinal push block and the transverse push block, positioning in two directions, namely the horizontal and vertical directions, is achieved. Through the design of the first guiding inclined surface and the second guiding inclined surface, an inclined surface guiding mechanism is formed, which is convenient for indirectly pushing the transverse push block, realizing non-powered two-way positioning, reducing the positioning deviation caused by power fluctuation or control error, thus ensuring the positioning consistency of the product and being beneficial to improving the positioning accuracy. By respectively arranging the first spring and the second spring between the longitudinal push block and the transverse push block and the bottom plate, the positioning carrier can automatically reset to achieve the clamping function when not driven by an external cylinder, thereby maintaining the stability of the structure of the positioning carrier and effectively reducing the positioning deviation caused by vibration or external force interference; and through the compression of the longitudinal push block and the transverse push block, the elastic force of the spring can be adjusted as needed to adapt to products of different sizes, improving the compatibility of the carrier with different products. In addition, the bottom plate, longitudinal push block, transverse push block, first spring and second spring of the positioning carrier in this case are all independent components, enabling each component to be replaced or adjusted separately to meet the positioning requirements of different sheet-shaped products. So when it is necessary to process products of different sizes and shapes, only the corresponding components need to be replaced or adjusted, without large-scale modification of the entire carrier, thus improving the compatibility and flexibility of the carrier.

[0019] 2. By setting the embedding slots and installing the longitudinal push block, transverse push block, longitudinal guide rail, and transverse guide rail into the embedding slots, the space in the bottom plate can be fully utilized, making the structure more compact, reducing the thickness of the positioning fixture, minimizing space occupation, and reducing costs. Specifically, the setting of the embedding slots can also prevent the swaying or offset of the push blocks during movement, enhancing the stability of the push block movement, thereby ensuring the safety and accuracy of the operation. The design of the longitudinal guide rail and transverse guide rail ensures that the longitudinal push block and transverse push block can maintain high-precision linear motion in their respective movement directions, reducing errors caused by movement deviation and improving the accuracy and reliability of the overall equipment. By dividing the embedding slots into two parts, longitudinal and transverse, the space on the bottom plate can be utilized more effectively, making the structure of the entire positioning carrier more compact and facilitating the realization of complex positioning functions in a limited space. The through-hole design on the longitudinal slot provides convenience for the external cylinder to extend. The cylinder can directly act on the longitudinal push block through the through-hole, reducing the intermediate transmission link and eliminating the need for a complex unlocking structure, thereby reducing the decline in positioning accuracy caused by transmission errors and contributing to more precise positioning control.

[0024] The following further details the features of the present utility model and other related features through embodiments for the understanding of those skilled in the same industry:

[0025] Figures 1 to 4As shown in the figure, a positioning carrier includes: a bottom plate 1, a longitudinal push block 2 disposed on the bottom plate 1 and capable of moving longitudinally driven by an external cylinder, and a transverse push block 3 capable of moving transversely driven by the longitudinal push block 2; a convex portion 20 is provided at the front end of the longitudinal push block 2 in the direction close to the transverse push block 3, and a first guiding inclined surface 21 is provided on the convex portion 20 and obliquely extends from front to back in the direction close to the transverse push block 3; the transverse push block 3 is provided with a second guiding inclined surface 31 that obliquely extends from back to front in the direction close to the longitudinal push block 2, and the first guiding inclined surface 21 and the second guiding inclined surface 31 are mutually attached; a first spring 41 is provided between the longitudinal push block 2 and the bottom plate 1 and can be compressed when the longitudinal push block 2 moves forward / drive the longitudinal push block 2 to rebound backward when not under force, and a second spring 42 is provided between the transverse push block 3 and the bottom plate 1 and can be compressed when the transverse push block 3 moves transversely to the right / drive the transverse push block 3 to rebound transversely to the left when not under force. In specific implementation, after the positioning carrier in this case is in place, the external cylinder extends to push the longitudinal push block 2 to move forward, and through the cooperation of the first guiding inclined surface 21 and the second guiding inclined surface 31, the longitudinal push block can smoothly drive the transverse push block to move to the right, so that the carrier is in an open state. When the product is placed in the carrier, the external cylinder retracts. Under the reaction force of the first spring and the second spring, the transverse push block returns to the left and the longitudinal push block returns backward, so that the carrier is in a closed state and clamps the product.

[0026] As described above, the structure of this case is simple and easy to implement. Through the mutual cooperation of the longitudinal push block 2 and the transverse push block 3, positioning in two directions, transverse and longitudinal, is achieved. Through the design of the first guiding inclined surface and the second guiding inclined surface, an inclined surface guiding mechanism is formed, which is convenient for indirectly pushing the transverse push block, realizing non-powered two-way positioning, reducing the positioning deviation caused by power fluctuation or control error, thus ensuring the positioning consistency of the product and being beneficial to improving the positioning accuracy. By respectively arranging the first spring and the second spring between the longitudinal push block and the transverse push block and the bottom plate, the positioning carrier can automatically reset to realize the clamping function when not driven by the external cylinder, thus maintaining the stability of the structure of the positioning carrier and effectively reducing the positioning deviation caused by vibration or external force interference; and through the compression of the longitudinal push block and the transverse push block, the elastic force of the spring can be adjusted as needed to adapt to products of different sizes, improving the compatibility of the carrier with different products. In addition, the bottom plate 1, the longitudinal push block 2, the transverse push block 3, the first spring 41 and the second spring 42 of the positioning carrier in this case are all independent components, so that each component can be replaced or adjusted separately to meet the positioning requirements of different sheet-shaped products. When it is necessary to process products of different sizes and shapes, only the corresponding components need to be replaced or adjusted, without large-scale modification of the entire carrier, thus improving the compatibility and flexibility of the carrier.

[0027] As Figure 3As shown, as a preferred embodiment, an embedding groove 5 for limiting and installing the longitudinal pushing block 2 and the transverse pushing block 3 therein is concavely provided on the bottom plate 1. A longitudinal guide rail 51 is installed on the bottom surface of the embedding groove 5 corresponding to the lower part of the longitudinal pushing block 2, and a transverse guide rail 52 is installed on the bottom surface of the embedding groove 5 corresponding to the lower part of the transverse pushing block 3. The longitudinal pushing block 2 moves longitudinally along the longitudinal guide rail 51 through a first slider 53, and the transverse pushing block 3 moves transversely along the transverse guide rail 52 through a second slider 54. Among them, the embedding groove 5 is provided with a longitudinal groove part 501 and a transverse groove part 502, and a through port 5010 is provided at one end of the longitudinal groove part 501 for an external air cylinder to extend into.

[0028] As described above, by providing the embedding groove 5 and installing the longitudinal pushing block 2, the transverse pushing block 3, the longitudinal guide rail 51, and the transverse guide rail 52 into the embedding groove, the space in the bottom plate can be fully utilized, making the structure more compact, reducing the thickness of the positioning fixture, reducing the space occupation, and reducing the cost. Specifically, the setting of the embedding groove can also prevent the pushing block from shaking or shifting during the movement process, enhancing the stability of the pushing block movement, thereby ensuring the safety and accuracy of the operation. The design of the longitudinal guide rail and the transverse guide rail ensures that the longitudinal pushing block and the transverse pushing block can maintain high-precision linear motion in their respective movement directions, reducing the errors caused by movement deviation, and improving the accuracy and reliability of the overall equipment. By subdividing the embedding groove into two parts, namely longitudinal and transverse, the space on the bottom plate can be utilized more effectively, making the structure of the entire positioning carrier more compact, which is beneficial to realizing complex positioning functions in a limited space. The design of the through port 5010 on the longitudinal groove part 501 provides convenience for the external air cylinder to extend into. The air cylinder can directly act on the longitudinal pushing block through the through port, reducing the intermediate transmission link and eliminating the need for a complex unlocking structure, thereby reducing the decrease in positioning accuracy caused by transmission errors and contributing to realizing more precise positioning control.

[0029] As Figure 1 As shown, as a preferred embodiment, a product support plate 6 is installed on the bottom plate 1, and the product support plate 6 covers the longitudinal pushing block 2 and the transverse pushing block 3. In this way, the product support plate 6 can serve as an isolation layer between the product and the pushing block, effectively preventing the product from directly contacting the pushing block during the positioning or moving process, avoiding damages such as scratches and collisions that may be caused by the movement of the pushing block, and thus protecting the appearance and quality of the product. At the same time, the product support plate 6 provides a stable support platform for the product to be positioned, enabling the product to remain relatively stationary during the positioning process, reducing the positioning errors caused by the shaking or shifting of the product itself, and improving the stability and accuracy of the positioning.

[0030] As Figure 1 and Figure 4As shown, as a preferred embodiment, a transverse limiting block 7 protrudes from the foremost end of the longitudinal pushing block 2, and a longitudinal limiting block 8 protrudes from the rightmost end of the transverse pushing block 3; both the transverse limiting block 7 and the longitudinal limiting block 8 are arranged on the outer edge of the product supporting plate 6. In this way, the arrangements of the transverse limiting block 7 and the longitudinal limiting block 8 both on the outer edge of the product supporting plate 6 ensure that they can form an effective limiting relationship with two reference points for product positioning, with the diagonal side as the reference, thereby achieving precise positioning of the product.

[0031] As Figure 1 shown, as a preferred embodiment, the bottom plate 1 protrudes with a plurality of uniformly arranged positioning posts 9 at the position of the outer edge of the product supporting plate 6, and the positioning posts 9 are arranged to avoid the transverse limiting block 7 and the longitudinal limiting block 8. In this way, through the arrangement of the positioning posts 9, the product can also be stably limited at positions other than the transverse limiting block 7 and the longitudinal limiting block 8.

[0032] As Figure 2 and Figure 3 shown, as a preferred embodiment, the bottom plate 1 is recessed downward on the surface near the through opening 5010 to form a first installation groove 11, and a first protective cover 12 is covered on the opening of the first installation groove 11. A first opening 13 facing the longitudinal pushing block 2 is provided on one side wall of the first installation groove 11. The longitudinal pushing block 2 protrudes with a first spring pressing block 22 passing through the first opening 13 and located in the first installation groove 11, and the first spring 41 is installed between the groove wall opposite to the first spring pressing block 22 in the front and back and the first spring pressing block 22. The bottom plate 1 is recessed downward on the surface near the transverse pushing block 3 to form a second installation groove 14, and a second protective cover 15 is covered on the opening of the second installation groove 14. A second opening 16 facing the transverse pushing block 3 is provided on one side wall of the second installation groove 14. The transverse pushing block 3 protrudes with a second spring pressing block 32 passing through the second opening 16 and located in the second installation groove 14, and the second spring 42 is installed between the groove wall opposite to the second spring pressing block 32 in the front and back and the second spring pressing block 32.

[0033] As described above, the provision of the first mounting groove 11 and the second mounting groove 14 enables the first spring and the second spring to be embedded inside the base plate 1, thereby reducing the occupation of external space and making the overall structure more compact. The coverage of the first protective cover 12 and the second protective cover 15 not only protects the internal springs from damage by external dust, dirt and accidental collisions, but also improves the safety and reliability of the device. In addition, when maintenance or spring replacement is required, the springs in the mounting grooves can be easily accessed by simply opening the corresponding protective covers, greatly simplifying the maintenance process. Moreover, the springs are firmly installed in the mounting grooves and are connected to the push block through the first spring pressing block 22 and the second spring pressing block 32. This design ensures that the springs can act on the push block evenly and stably when pressure is applied, thereby improving the positioning accuracy of the product.

[0034] As a preferred embodiment, both the first guiding inclined surface 21 and the second guiding inclined surface 31 are inclined surfaces at 45 degrees. In this way, the 45-degree inclined surface design enables the push block, whether it is a longitudinal push block or a transverse push block, to slide more smoothly along the inclined surface during movement, reducing the phenomenon of jamming or increased resistance caused by too large or too small an angle, and contributing to improving the movement efficiency and accuracy of the push block.

[0035] As Figure 2 shown, as a preferred embodiment, a positioning sensing screw 10 for sensing whether the product is in place is provided on the base plate 1. In specific implementation, the positioning sensing screw is a special screw integrated with a sensing function. It can not only achieve the fastening function of a traditional screw, but also has the ability of in-place sensing. In specific implementation, when the product is placed on the base plate, the positioning sensing screw will trigger a sensing signal and send it to the control system for reception and corresponding reaction, such as a clamping action.

[0036] As described above, the present case protects a positioning carrier, and all technical solutions identical or similar to those of the present case should be regarded as falling within the protection scope of the present case.
