Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly, in particular to a multi-function material displacement mechanism. Background Art

[0002] In the product assembly of automated production lines, nuts are often used to fix products. In order to cooperate with automated production lines, nuts and products to be assembled are generally transported to assembly stations separately, and then the nuts are assembled to the nut assembly positions of the products (i.e., the nut installation positions pre-set for the products). However, existing products and nuts are transported through different material transfer mechanisms, which not only makes the transport path design complicated, but also takes a long time, seriously affecting production efficiency. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide a multi-function material shifting mechanism that can simultaneously take and place products and nuts, so as to simplify the material shifting path and improve production efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a multi-station material displacement mechanism, installed on a multi-axis manipulator, used to move parts to the assembly station; the multi-station material displacement mechanism includes a material displacement substrate and a product pick-up and placement component and a nut pick-up and placement component arranged on the material displacement substrate; wherein,

[0005] The nut picking and placing assembly comprises at least one group of nut picking and placing parts arranged in parallel, each group of the nut picking and placing parts comprises at least one nut picking and placing member, each of the nut picking and placing members comprises at least one picking rod arranged corresponding to the number of nut assembly positions of the product, the picking rod is arranged on the material moving base plate in a direction perpendicular to the material moving base plate, and a push member which can move axially along the picking rod is mounted thereon;

[0006] The product picking and placing assembly includes at least one group of product picking and placing parts corresponding to the nut picking and placing parts, each group of the product picking and placing parts includes a product picking and placing substrate that can be flipped under the action of a flip driving member, and the product picking and placing substrate is provided with a product picking and placing member corresponding to the nut picking and placing member.

[0007] When in use, the material transfer substrate is moved to the product loading station and the nut loading station respectively, and the product at the product loading station is picked up by the product picking and placing component, and the nuts on the nut loading station are picked up by the nut picking and placing component; then the material transfer substrate is driven by the multi-axis manipulator to move to the assembly station, and the nuts picked up by the nut picking and placing component and the products picked up by the product picking and placing component are sent to the assembly station in turn; when the assembly is completed, the assembled product can be taken away from the self-assembly station by the product picking and placing component.

[0008] The beneficial effects of the multi-function material displacement mechanism of the utility model are:

[0009] In the nut picking and placing assembly and the product picking and placing assembly, at least one nut picking and placing member of at least one group of nut picking and placing parts cooperates with the product picking and placing member of at least one product picking and placing part, so as to achieve the purpose of picking up multiple nuts and products at the same time, so as to further improve the assembly efficiency; and in the product picking and placing assembly, the product picking and placing substrate is driven to flip by the flip driving member, so as to avoid the movement of the nut picking and placing assembly, so as to ensure that the product picking and placing assembly and the nut picking and placing assembly can face the assembly station in sequence, so as to send the product and the nut to the assembly station. In the nut picking and placing assembly, the setting of the material picking rod can not only clamp the nut, but also guide the nut in the process of the push member pushing the nut to move to the assembly station, so as to ensure that the nut smoothly enters the assembly station. The present application integrates the product picking and placing assembly and the nut picking and placing assembly on the material transfer substrate, so that the material transfer substrate can simultaneously have the function of picking up and placing products and nuts. Compared with the prior art, the material transfer path for picking up products and nuts can be reduced, and the production efficiency is improved.

[0010] Specifically, the nut picking and placing part includes a nut picking and placing base fixedly connected to the material moving base plate, one end of all the picking rods of the nut picking and placing part is fixedly connected to the nut picking and placing base plate, and the other end of each rod passes through the material moving base plate and forms a picking end for the nut to be fitted. The outer diameter of the picking end should be adapted to the inner diameter of the nut, so that the nut can be fitted on the picking end.

[0011] Furthermore, a guide cone head is integrally provided at the end of the material taking end to facilitate taking out the nuts from the nut loading station.

[0012] Furthermore, the nut picking and placing part includes a picking and placing driving member installed on the nut picking and placing base, and the picking and placing driving member is used to drive all the push members of the nut picking and placing part to move synchronously. The picking and placing driving member drives all the push members to move synchronously, so that the nuts on the nut picking and placing part enter the assembly station synchronously, thereby improving efficiency.

[0013] Specifically, the pick-and-place drive member includes a pick-and-place cylinder, a synchronous plate, and a synchronous guide rod; the synchronous plate is connected to all the push members of the nut pick-and-place portion, and is connected to the piston rod of the pick-and-place cylinder; the synchronous guide rod is arranged through the synchronous plate, one end of which is fixed to the material transfer base plate, and the other end passes through the nut pick-and-place base. The synchronous guide rod can guide the movement of the synchronous plate to ensure the uniformity of the movement of multiple push members.

[0014] Furthermore, the material moving substrate is also provided with a pressing piece corresponding to the material picking rod, and the pressing piece is arranged in a direction perpendicular to the material picking rod. When the nut is fitted onto the material picking end, the pressing piece can elastically press against the nut. The setting of the pressing piece can apply pressure to the nut on the material picking end to ensure the stability of the nut at the material picking end.

[0015] Furthermore, the product placement substrate can be flipped back and forth between the first position and the second position under the action of the flip driving member. When the product placement substrate is flipped to the first position, the product placement substrate is parallel to the material transfer substrate and is located below the material transfer substrate. At this time, the product placement member faces the assembly station; when the product placement substrate is flipped to the second position, the product placement substrate can be perpendicular to the material transfer substrate. At this time, the product placement member does not face the assembly station.

[0016] In actual application, the multi-axis manipulator drives the material transfer substrate to move close to the assembly station (the material transfer substrate is parallel to the assembly station), and the product pick-up and placement substrate is located at the second position. At this time, the nut pick-up and placement component can face the assembly station (the screw locking mechanism), and the nut pick-up and placement component sends the nut to the assembly station; then the multi-axis manipulator drives the material transfer substrate to move upward, and the nut pick-up and placement component and the product pick-up and placement substrate move upward immediately, and the flip drive component drives the product pick-up and placement substrate to flip to the first position, so that the product pick-up and placement component can face the assembly station (the product positioning mechanism) to send the product to the assembly station. The flip drive component drives the product pick-up and placement substrate to flip, so that the product pick-up and placement substrate can be turned around at the assembly station to avoid flipping, so as to ensure that the nut pick-up and placement component can move smoothly to the assembly station.

[0017] Furthermore, the product picking and placing component includes a first suction rod and a second suction rod used in conjunction with each other. The first suction rod and the second suction rod are arranged along the diagonal direction of the product to suck the product.

[0018] Furthermore, on the same product placement substrate, an auxiliary clamping member is provided between any two adjacent product placement members, the auxiliary clamping member comprising a clamping member body, and a side of the clamping member body facing any product placement member is provided with a push convex portion that can abut against the product. The auxiliary clamping member can be provided to enhance the clamping of the product in a clamping direction different from that of the product placement member.

[0019] Furthermore, the auxiliary clamping member also includes a pneumatic clamping jaw installed on the product placement substrate, and the pneumatic clamping jaw is used to clamp or release the clamping member body. The pneumatic clamping jaw quickly clamps the clamping member body, making it easy to replace the clamping member body according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0031] Example

[0032] See attached Figure 1-4 As shown, a multi-station material shifting mechanism of the utility model is installed on a multi-axis manipulator (not shown in the figure) to move parts to the assembly station. The multi-station material shifting mechanism includes a material shifting substrate 1 and a product pick-up and placement assembly 2 and a nut pick-up and placement assembly 3 arranged on the material shifting substrate 1. Among them, the nut pick-up and placement assembly 3 includes at least one group of nut pick-up and placement parts arranged in parallel, each group of nut pick-up and placement parts includes at least one nut pick-up and placement member, and each nut pick-up and placement member includes at least one material picking rod 31 arranged corresponding to the number of nut assembly positions of the product, and the material picking rod 31 is arranged on the material shifting substrate 1 in a direction perpendicular to the material shifting substrate 1, and a push member 32 that can move axially along the material picking rod 1 is mounted thereon. The product pick-up and placement assembly includes at least one group of product pick-up and placement parts arranged corresponding to the nut pick-up and placement parts, and each group of product pick-up and placement parts includes a product pick-up and placement substrate 22 that can be flipped under the action of a flip driving member 21, and a product pick-up and placement member arranged corresponding to the nut pick-up and placement member is provided on the product pick-up and placement substrate 22.

[0033] For ease of understanding, the working principle of the assembly station is explained below. During layout, a screw locking mechanism and a product positioning mechanism are placed on the assembly station. When the nut is delivered to the assembly station, the screw locking mechanism can clamp the nut. When the product 4 is delivered to the assembly station, the product positioning mechanism can clamp the product 4 and align the nut assembly position of the product with the nut on the screw locking mechanism; then the screw locking mechanism locks the nut to the nut assembly position of the product. Since this embodiment is intended to improve the material transfer mechanism, the structure of the assembly station will not be described in detail in the following embodiments. The material transfer mechanism only needs to deliver the nut and the product 4 to the assembly station.

[0034] When using the material transfer mechanism of this embodiment, the material transfer substrate 1 can be moved to the product loading station and the nut loading station respectively, and the product 4 at the product loading station is taken by the product pick-up and placement component 2, and the nuts at the nut loading station are taken by the nut pick-up and placement component 3; then the material transfer substrate 1 is driven by the multi-axis manipulator to move to the assembly station, and the nuts taken by the nut pick-up and placement component 3 and the products 4 taken by the product pick-up and placement component 2 are sequentially sent to the assembly station; when the assembly is completed, the assembled products can be taken away from the assembly station by the product pick-up and placement component 4. In the nut pick-up and placement component 3 and the product pick-up and placement component 2, at least one nut pick-up and placement member of at least one group of nut pick-up and placement parts is used to cooperate with the product pick-up and placement member of at least one product pick-up and placement part, so as to achieve the purpose of taking multiple nuts and products 4 at the same time, so as to further improve the assembly efficiency. For example, the nut pick-up and placement part is provided with two groups, and each group of nut pick-up and placement parts is provided with two nut pick-up and placement members. Similarly, the product pick-up and placement part is provided with two groups, and each group of product pick-up and placement parts is also provided with two product pick-up and placement members. This arrangement enables synchronous transport of four products and corresponding nuts during the one-way movement of the material shifting assembly. In the present embodiment, two nut assembly positions are provided on the product, so each nut pick-and-place member is also provided with two pick-up rods.

[0035] In some embodiments, see Appendix Figure 3 , 5 As shown, the nut picking and placing part includes a nut picking and placing base 33 fixedly connected to the material transfer substrate 1, one end of all the picking rods 31 of the nut picking and placing part is fixedly connected to the nut picking and placing base 33, and the other end passes through the material transfer substrate 1 to form a picking end 311 for the nut to be fitted. The outer diameter of the picking end 311 should be compatible with the inner diameter of the nut, so that the nut can be fitted on the picking end 311. Furthermore, the end of the picking end 311 is integrally provided with a guide cone head to fit the nut onto the picking end 311.

[0036] In some embodiments, the nut picking and placing part includes a picking and placing driving member installed on the nut picking and placing base 33, and the picking and placing driving member is used to drive all the push members 32 of the nut picking and placing part to move synchronously. Specifically, the picking and placing driving member includes a picking and placing cylinder 34, a synchronization plate 35, and a synchronization guide rod 36. The synchronization plate 35 is located between the nut picking and placing base 33 and the material moving base 1, and is connected to all the push members 32 of the nut picking and placing part, and is connected to the piston rod of the picking and placing cylinder 34. The synchronization guide rod 36 is arranged on the synchronization plate 35, one end of which is fixed to the material moving base 1, and the other end passes through the nut picking and placing base 33. When the picking and releasing cylinder 34 is extended, the synchronous plate 35 immediately moves along the synchronous guide rod 36 toward the direction close to the material moving base plate 1, and all the pushing members 32 immediately move toward the picking end 311 under the action of the synchronous plate 35 to push against the nut at the picking end 311. As the pushing members 32 continue to move, the nut is immediately pushed out of the picking end 311 (the nut immediately enters the assembly station); when the picking and releasing cylinder 34 is retracted, the synchronous plate 35 drives all the pushing members 32 to move toward the nut picking and placing base 33, so as to facilitate the nut to be installed at the picking end 311.

[0037] Furthermore, in order to prevent the nut from accidentally slipping off the material picking end 311 during the material moving process, in some embodiments, a pressure piece 37 is also provided on the material moving substrate 1, which is arranged one by one in correspondence with the material picking rod 31. The pressure piece 37 is arranged in a direction perpendicular to the material picking rod 31. When the nut is put on the material picking end 311, the pressure piece 37 can elastically press on the nut to apply pressure to the nut in a direction perpendicular to the material picking rod 31, thereby ensuring the stability of the nut at the material picking end 311.

[0038] In some embodiments, see Appendix Figure 4-5 As shown, the product pick-up and placement substrate 22 can be flipped back and forth between the first position and the second position under the action of the flip driving member 21 (such as a flip cylinder). When the product pick-up and placement substrate 22 flips to the first position, the product pick-up and placement substrate 22 is parallel to the material moving substrate 1 and is located below the material moving substrate 1. At this time, the product pick-up and placement member faces the assembly station; when the product pick-up and placement substrate 22 flips to the second position, the product pick-up and placement substrate 22 can be perpendicular to the material moving substrate 1. At this time, the product pick-up and placement member does not face the assembly station.

[0039] In actual application, the multi-axis manipulator drives the material moving substrate 1 to move close to the assembly station (the material moving substrate 1 is parallel to the assembly station), and the product picking and placing substrate 22 is located at the second position. At this time, the nut picking and placing component can face the assembly station (the screw locking mechanism), and the nut picking and placing component sends the nut to the assembly station; then the multi-axis manipulator drives the material moving substrate 1 to move upward, and the nut picking and placing component and the product picking and placing substrate 22 move upward immediately, and the flipping drive component drives the product picking and placing substrate 22 to flip to the first position, so that the product picking and placing component can face the assembly station (the product positioning mechanism) to send the product 4 to the assembly station.

[0040] In some embodiments, the product picking and placing component includes a first suction rod 23 and a second suction rod 24 that are used in conjunction with each other. The first suction rod 23 and the second suction rod 24 are arranged along the diagonal direction of the product to suck the product 4.

[0041] Furthermore, on the same product placement substrate 22, an auxiliary clamping member is provided between any two adjacent product placement members, and the auxiliary clamping member includes a clamping member body, and a side of the clamping member body facing any product placement member is provided with a push convex portion that can abut against the product 4. The provision of the auxiliary clamping member can enhance the clamping of the product 4 from a clamping direction different from that of the product placement member. Furthermore, the auxiliary clamping member also includes a pneumatic clamping jaw 25 installed on the product placement substrate 22, and the pneumatic clamping jaw 25 is used to clamp or release the clamping member body. The rapid clamping of the clamping member body by the pneumatic clamping jaw 25 facilitates the replacement of the clamping member body according to actual needs.

[0042] The specific working process of this embodiment is as follows:

[0043] First, the material moving substrate 1 is moved to the product loading station and the nut loading station respectively, and the product picking and placing part absorbs the product 4 at the product loading station, and the material picking rod 31 takes the nut on the nut loading station; then the multi-axis manipulator drives the material moving substrate 1 to move to the assembly station, and the flip driving part 21 drives the product picking and placing substrate 22 to flip to the second position, and the multi-axis manipulator drives the material moving substrate 1 to continue to move downward so that the material picking rod 31 faces the assembly station, and the picking and placing driving part immediately drives the push part 32 to push the nut into the assembly station; the multi-axis manipulator drives the material moving substrate 1 to move upward, and the flip driving part 21 drives the product picking and placing substrate 22 to flip to the first position so that the product 4 on the product picking and placing part faces the assembly station and enters the assembly station, and the assembly station immediately assembles the nut to the nut assembly position of the product; when the assembly is completed, the product picking and placing part takes the assembled product 4 away from the assembly station under the action of the multi-axis manipulator.

[0044] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
