[0044] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0045] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0047] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0048] This embodiment provides a lifting and flipping device, which can be used to clamp, lift and flip a workpiece, so that the posture of the workpiece meets the processing requirements and improves the convenience of the workpiece assembly process. In this embodiment, the workpiece can be the base of the environmental test box. In other embodiments, the workpiece can also be other parts with larger mass, which is not specifically limited here.

[0049] Figure 1 The X direction, Y direction and Z direction are three directions that are perpendicular to each other. The X direction and the Y direction represent the first direction and the second direction of the horizontal setting, respectively, and the Z direction represents the vertical direction. Figure 1 As shown, the lifting and flipping device includes two bracket mechanisms 10, two lifting drive mechanisms 20, two flipping drive mechanisms 30, two support mechanisms 50, a carrier frame 40 and a clamping assembly 60. The two bracket mechanisms 10 are arranged along a first direction (i.e. Figure 1The two support mechanisms 10 are arranged at intervals (in the X direction in the figure), each lifting drive mechanism 20 is correspondingly installed on a support mechanism 10, and each support mechanism 50 is correspondingly connected to the output end of a lifting drive mechanism 20 and cooperates with the corresponding support mechanism 10 guide. The flipping drive mechanism 30 is installed on the support mechanism 50, so that the lifting drive mechanism 20 can drive the corresponding flipping drive mechanism 30 to move up and down in the vertical direction. The carrier 40 is arranged parallel to the first direction and is located between the two support mechanisms 10. The clamping assembly 60 is arranged on the carrier 40 and can clamp and fix the workpiece on the carrier 40. The output ends of the two flipping drive mechanisms 30 are connected to the carrier 40 and can drive the carrier 40 to rotate around the flipping axis parallel to the X direction.

[0050] When the lifting and flipping device of this embodiment is used to assemble the base, the two lifting drive mechanisms 20 can first drive the carrier 40 downward to a position close to the ground, so that the clamping assembly 60 on the carrier 40 can directly grab the base placed on the ground; then the two lifting drive mechanisms 20 jointly lift the carrier 40, the clamping assembly 60 and the base to a height sufficient for the base to flip; then the two flipping drive mechanisms 30 jointly drive the carrier 40 and the base to flip around a flip axis parallel to the first direction, so as to adjust the base to the required tilt angle. The lifting and flipping device of this embodiment can automatically grasp, lift and flip the base, without the need for manual handling of the base, with high operating efficiency and low labor costs. In addition, since the mass of the base is large, the two lifting drive mechanisms 20 jointly drive the carrier 40 to rise and fall, and the two flipping drive mechanisms 30 jointly drive the carrier 40 to flip, so that the force of the carrier 40 is balanced, and the lifting and flipping of the base are also made more stable.

[0051] like Figure 1As shown, the carrier 40 is a frame structure welded by a plurality of channel steels, which not only has good structural strength, but also is light in weight relative to the plate, thereby reducing the driving load of the lifting drive mechanism 20 and the flipping drive mechanism 30. Optionally, the clamping assembly 60 includes two groups of first clamping cylinders 61 and two clamping head assemblies 62, and the two first clamping cylinders 61 are both mounted on the carrier 40, and the output ends extend along the first direction. The output directions of the two groups of first clamping cylinders 61 are opposite, and each clamping head assembly 62 is correspondingly connected to the output end of a first clamping cylinder 61, so the two first clamping cylinders 61 can drive the two groups of clamping head assemblies 62 to approach or move away from each other along the first direction, thereby being able to clamp the base in the first direction. In some embodiments, the clamp assembly 62 includes a second clamping cylinder 621 and a clamping member 622. The second clamping cylinder 621 can drive the clamping member 622 to move vertically and / or in the first direction, so that the clamping member 622 can press the base against the carrier 40, thereby improving the reliability of the clamping assembly 60 clamping the base. Of course, the above only provides a structural form of a clamping assembly 60. In other embodiments, the clamping assembly 60 can be flexibly configured as needed, which is not specifically limited here.

[0052] like Figure 2 As shown, the support mechanism 10 includes a bottom plate 13, a top plate 14 and two H-shaped steels 11, wherein the bottom plate 13 is used to be placed on the ground, and a mounting hole is provided on the bottom plate 13, so that the bottom plate 13 can be fixed to the ground by bolts to improve the stability of the support of the support mechanism 10. The two H-shaped steels 11 are both installed on the bottom plate 13 and extend in the vertical direction (i.e. Figure 2 The top plate 14 is installed on the top of the H-shaped steel 11. The cooperation of the bottom plate 13, the top plate 14 and the two H-shaped steels 11 makes the entire bracket mechanism 10 have a high structural strength. For the H-shaped steel 11, its cross section is H-shaped and includes a web 111 and two flange plates 112. In this embodiment, the webs 111 of the two H-shaped steels 11 are arranged along the second direction (i.e. Figure 2 The two flange plates 112 of each H-shaped steel 11 are arranged in the first direction (i.e., the Y direction in the figure), and each web plate 111 is perpendicular to the second direction. Figure 2 The flange plates 112 are arranged opposite to each other in the X direction, and the flange plates 112 are perpendicular to the first direction, so that an accommodating space 12 is formed between the two H-shaped steels 11 at this time.

[0053] like Figure 2As shown, the lifting drive mechanism 20 is installed on the top plate 14, and the output end extends downward into the accommodating space 12. The support mechanism 50 includes a support inner frame 51, and the support inner frame 51 is arranged in the accommodating space 12 formed by two H-shaped steels 11. The output end of the lifting drive mechanism 20 is connected to the support inner frame 51, and the flipping drive mechanism 30 is installed on the support inner frame 51. The bracket mechanism 10 is composed of H-shaped steel 11, which not only has good structural strength, but also naturally forms an accommodating space 12 that can accommodate the output end of the lifting drive mechanism 20 and the flipping drive mechanism 30, which not only protects the lifting drive mechanism 20 and the flipping drive mechanism 30, but also prevents accidental injury to the operator. Optionally, the lifting drive mechanism 20 can be a component that can output linear motion, such as an oil cylinder or a pneumatic cylinder, which is not specifically limited here.

[0054] like Figure 2 As shown, the support mechanism 10 also includes an upper limit member 15 and a lower limit member 16, wherein the upper limit member 15 is connected to the upper end of the H-shaped steel 11, and the upper limit member 15 can stop the support mechanism 50 from moving upward, thereby limiting the maximum movement height of the support mechanism 50 and the carrier 40. The lower limit member 16 is connected to the lower end of the H-shaped steel 11, and the lower limit member 16 can stop the support mechanism 50 from moving downward, thereby limiting the minimum movement height of the support mechanism 50 and the carrier 40, and preventing the carrier 40 from colliding with the base. In this embodiment, the upper limit member 15 is a plate, and its two ends along the Y direction are respectively connected to the two H-shaped steels 11. The lower limit member 16 is also a plate, and its two ends along the Y direction are respectively connected to the two H-shaped steels 11.

[0055] like Figure 3As shown, the flip driving mechanism 30 includes a rotating motor 31 and a transmission assembly 32, wherein the rotating motor 31 is mounted on the supporting inner frame 51 and is located in the accommodating space 12, and the output shaft of the rotating motor 31 extends in the vertical direction. The input end of the transmission assembly 32 is connected to the output shaft of the rotating motor 31, and the output shaft 323 of the transmission assembly 32 extends in the first direction and is connected to the carrier 40. The accommodating space 12 formed by the two H-shaped steels 11 has a larger size in the vertical direction. In this embodiment, by setting the output shaft of the rotating motor 31 to extend in the vertical direction, the flip driving mechanism 30 is elongated in the vertical direction and has a smaller size in the horizontal plane, thereby making the structure of the bracket mechanism 10 more compact. By setting the transmission assembly 32, the rotation of the vertical axis output by the rotating motor 31 is converted into the rotation of the first direction axis, thereby driving the carrier 40 to rotate around the axis in the first direction. Optionally, in this embodiment, the transmission assembly 32 includes a first bevel gear 321, a second bevel gear 322 and an output shaft 323, wherein the first bevel gear 321 is connected to the output end of the rotating motor 31, the second bevel gear 322 is meshed with the first bevel gear 321, the output shaft 323 is coaxially arranged with the second bevel gear 322 and is rotatably mounted on the support mechanism 50, and the output shaft 323 is fixedly connected to the carrier frame 40, thereby driving the carrier frame 40 to rotate around the axis extending in the first direction.

[0056] In some embodiments, such as Figure 3 As shown, the flipping drive mechanism 30 also includes two limit switches 33, and a trigger 34 is connected to the output shaft 323. The two limit switches 33 are respectively arranged on both sides of the output shaft 323. When the output shaft 323 rotates to the maximum angle in the clockwise direction, the trigger 34 triggers one of the limit switches 33, so that the rotating motor 31 stops outputting and rotating. When the output shaft 323 rotates to the maximum angle in the counterclockwise direction, the trigger 34 triggers the other limit switch 33, so that the rotating motor 31 stops outputting and rotating. By setting two limit switches 33, the flipping angle of the carrier 40 can be limited, so as to avoid the carrier 40 from rotating continuously in the same rotation direction and causing the line to be entangled.

[0057] Preferably, the center of the support frame 40 is located on the extension line of the output shaft 323. This arrangement enables the support frame 40 to maintain dynamic balance, thereby improving the stability of the lifting and flipping device during operation.

[0058] like Figure 2 and Figure 4As shown, the support mechanism 50 also includes a support outer frame 52 and a guide assembly 53. The support outer frame 52 is connected to the support inner frame 51 and is arranged around the outer periphery of the two H-shaped steels 11. The guide assembly 53 is connected to the support outer frame 52 and is in rolling cooperation with the H-shaped steel 11. The support mechanism 50 in this embodiment supports the flip drive mechanism 30 located in the accommodating space 12 by setting the support inner frame 51, and realizes rolling cooperation with the H-shaped steel 11 by setting the support outer frame 52 and the guide assembly 53, thereby ensuring the stability of the lifting process, and making full use of the space inside and outside the H-shaped steel 11, so that the structure of the lifting and flipping device at the bracket mechanism 10 is more compact. In addition, since the carrier 40 is driven by two lifting drive mechanisms 20, this embodiment guides the guide assembly 53 and the H-shaped steel 11 by rolling cooperation. Compared with the guide structure of the guide rail slider, it has a larger tolerance, thereby avoiding the problem of the carrier 40 being stuck during the lifting process.

[0059] In this embodiment, Figure 3 As shown, the supporting inner frame 51 includes two first supporting plates 511 arranged opposite to each other in the vertical direction and two second supporting plates 512 arranged opposite to each other in the second direction. The two first supporting plates 511 and the two second supporting plates 512 are jointly arranged to form a frame, and the opening of the frame is opposite to the opening of the accommodating space 12 surrounded by the two H-shaped steels 11, thereby improving the convenience of assembling the lifting and flipping device.

[0060] In this embodiment, Figure 4 As shown, the supporting outer frame 52 includes two first side plates 521 spaced apart along the second direction and two second side plates 522 spaced apart along the first direction. The two first side plates 521 and the two second side plates 522 are arranged to form a frame with upper and lower ends opened, so as to be conveniently mounted on the outer sides of the two H-shaped steels 11. Optionally, as Figure 3 As shown, the first support plate 511 of the inner support frame is provided with connecting protrusions 5111 at both ends along the first direction. The connecting protrusions 5111 pass through the gap between the two H-shaped steels 11 and are connected to the supporting outer frame 52, thereby realizing the connection between the supporting inner frame 51 and the supporting outer frame 52.

[0061] like Figure 4 and Figure 5As shown, the guide assembly 53 is provided with two groups of first roller assemblies 531 corresponding to each H-beam 11, and the two groups of first roller assemblies 531 are respectively used to cooperate with the two flange plates 112 of the H-beam 11. Each group of first roller assemblies 531 includes a plurality of first rollers 5311, and the first rollers 5311 can rotate around an axis parallel to the Y direction and can roll with the corresponding flange plates 112. The two groups of first roller assemblies 531 can respectively press the two flange plates 112 of the H-beam 11 along the first direction, so that the support mechanism 50 is limited and guided relative to the bracket mechanism 10 along the first direction, thereby improving the movement accuracy of the support mechanism 50 (and the flip drive mechanism 30 thereon) relative to the bracket mechanism 10. In this embodiment, each group of first roller assemblies 531 includes multiple first rollers 5311, and the multiple first rollers 5311 are arranged at intervals in the vertical direction. The multiple first rollers 5311 are all rollingly matched with the corresponding flange plates 112. The arrangement of the multiple first rollers 5311 further improves the movement accuracy of the support mechanism 50 relative to the bracket mechanism 10.

[0062] In this embodiment, Figure 4 and Figure 5 As shown, the first side plate 521 is provided with a long hole extending in the first direction, and the first roller assembly 531 also includes a mounting plate 5313 and a plurality of first rollers 5312, the number of the first rollers 5312 being equal to the number of rollers. The mounting plate 5313 is arranged outside the support outer frame 52, and the first roller 5312 extends in the second direction, and one end is connected to the mounting plate 5313, and the other end is penetrated with a long hole and connected to the first roller 5311. Such a setting not only ensures that the first roller 5311 can abut against the corresponding flange plate 112, but also facilitates the installation of the first roller assembly 531 on the support outer frame 52.

[0063] Preferably, if Figure 5 As shown, the guide assembly 53 also includes an adjusting member 533. At least one of the two first roller assemblies 531 corresponding to the same H-beam 11 is equipped with an adjusting member 533. The adjusting member 533 can adjust the position of the first roller assembly 531 along the X direction so that the first roller 5311 abuts against or forms a gap with the corresponding flange plate 112. In the process of assembling the lifting and flipping device, the adjusting member 533 can be operated to form a gap between the first roller 5311 and the corresponding flange plate 112. At this time, it is convenient to sleeve the support outer frame 52 and the guide assembly 53 on the outer periphery of the two H-beams 11. When the lifting and flipping device is assembled, the first roller assembly 531 is operated to approach the corresponding flange plate 112 along the first direction, so that the first roller 5311 rolls with the corresponding flange plate 112, thereby guiding the movement of the support mechanism 50 relative to the bracket mechanism 10. In this embodiment, only one of the two first roller assemblies 531 corresponding to the same H-beam 11 Figure 5 The first roller assembly 531 on the left side is provided with an adjusting member 533. In other embodiments, the two first roller assemblies 531 corresponding to one H-shaped steel 11 can both be provided with an adjusting member 533, thereby further improving the convenience of assembling the supporting mechanism 50.

[0064] Specifically, Figure 4 and Figure 5 As shown, the second side plate 522 of the supporting outer frame 52 has a protrusion 5221 protruding from the first side plate 521 along the second direction, and the protrusion 5221 is provided with a through hole 5222. A threaded hole 5314 is provided at a position corresponding to the through hole 5222 on the mounting plate 5313, and the adjusting member 533 is penetrated with the through hole 5222 along the first direction and is threadedly connected with the threaded hole 5314. When the adjusting member 533 is rotated, the mounting plate 5313 moves along the X direction and drives the first roller 5312 to slide along the long hole, and the first roller 5311 moves along the X direction synchronously, and then approaches the corresponding flange plate 112 and rolls with the flange plate 112, or moves away from the corresponding flange plate 112 and forms a gap between the flange plate 112 for easy assembly. In this embodiment, the through hole 5222 is a countersunk hole, and the adjusting member 533 is a bolt, and the head of the bolt is limited in the countersunk hole, so that the first roller assembly 531 can move along the first direction when the adjusting member 533 is rotated.

[0065] like Figure 4 and Figure 5 As shown, the guide assembly 53 also includes two groups of second roller assemblies 532, both of which are connected to the support outer frame 52 and are respectively located on the sides of the webs 111 of the two H-shaped steels 11 away from each other, and the second roller assembly 532 includes a plurality of second rollers 5322, which can rotate around an axis parallel to the X direction and roll with the corresponding webs 111. The two groups of second roller assemblies 532 can respectively press the webs 111 of the H-shaped steel 11 along the second direction, so that the support mechanism 50 is limited and guided along the second direction relative to the bracket mechanism 10, thereby improving the motion accuracy of the support mechanism 50 (and the flip drive mechanism 30 thereon) relative to the bracket mechanism 10. In this embodiment, each second roller assembly 532 includes a plurality of second rollers 5322, which are arranged at intervals along the vertical direction and roll with the corresponding webs 111. The arrangement of the plurality of second rollers 5322 further improves the motion accuracy of the support mechanism 50 relative to the bracket mechanism 10.

[0066] Optionally, the second roller assembly 532 also includes a connecting plate 5321 and a plurality of second rollers, the connecting plate 5321 being mounted on a side of the first side plate 521 facing the corresponding frontal plate 111, the second rollers extending along the X direction and connected to the connecting plate 5321, and each second roller 5322 being correspondingly mounted on a second roller and being able to rotate relative to the second roller.

[0067] In summary, this embodiment, by configuring the guide assembly 53 to include a first roller assembly 531 and a second roller assembly 532, can not only provide good guidance for the movement of the support mechanism 50 relative to the bracket mechanism 10, but also fully utilize the position of the H-shaped steel 11 outside the accommodating space 12.
