[0046] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is 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 the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

[0047] 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.

[0048] In the present invention, 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.

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.

[0049] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] During the production process of the environmental test chamber, multiple workers are required to manually flip the chamber and turn the side of the bottom of the chamber to the top, so as to fully weld the surface originally located at the bottom and assemble and weld other auxiliary parts. Since the chamber is a large rectangular or cubic structure with a heavy weight, the manual flipping of the chamber will cause high labor intensity and low work efficiency. In addition, the chamber is prone to damage during flipping, and may even cause harm to the workers, resulting in high safety risks in the flipping of the chamber.

[0052] To solve the above problems, Figure 1 As shown, this embodiment proposes a flipping device, which includes a base 1, two flipping frames 2 and a driving assembly. The two flipping frames 2 are arranged side by side on the base 1, and the ends of the two flipping frames 2 close to each other are both pivotally connected to the base 1. The driving assembly is connected to the two flipping frames 2 in a transmission manner to drive the two flipping frames 2 to rotate independently or synchronously relative to the base 1, so that the two flipping frames 2 can be arranged at an angle and form a bracket for accommodating the part to be flipped, and the two flipping frames 2 respectively support two adjacent sides of the part to be flipped. The driving assembly drives the two flipping frames 2 to rotate relative to the base 1 to form a bracket, and the part to be flipped is placed on the bracket. The driving assembly drives the bracket to rotate to flip different sides of the part to be flipped in the bracket to the top surface, thereby realizing the automatic flipping of the part to be flipped, improving the flipping efficiency of the part to be flipped, and at the same time, no manual flipping is required, which not only reduces the workload of the staff, but also avoids damage to the part to be flipped and the operator during the flipping process, and improves the safety of the flipping process.

[0053] It should be noted that the part to be flipped in this embodiment is a box body of an environmental test box, and the box body is a rectangular parallelepiped or cubic structure, that is, two adjacent side surfaces of the box body are at right angles. In other embodiments, the part to be flipped can also be other boxes, boxes or shells, etc. Since most common boxes are rectangular parallelepiped or cubic structures, the two flip frames 2 in this embodiment are arranged at right angles to form a bracket with a right-angle L-shaped structure. Of course, when the angle between the two adjacent side surfaces of the part to be flipped is not a right angle, the angle between the two flip frames 2 in the bracket can be adaptively adjusted, and no specific limitation is made here.

[0054] Specifically, the driving assembly includes a first driving member 3 and a second driving member 4. The first driving member 3 is mounted on the base 1, and the output end of the first driving member 3 is connected to one of the flip frames 2. The second driving member 4 is mounted on the base 1, and the output end of the second driving member 4 is connected to the other flip frame 2. The two driving members drive the corresponding flip frames 2 respectively, so that the two flip frames 2 rotate independently relative to the base 1. At the same time, when the two driving members synchronously drive the corresponding flip frames 2, the two flip parts can be synchronously rotated, so that the bracket rotates relative to the base 1 to complete the flipping action of the part to be flipped.

[0055] The first driving member 3 and the second driving member 4 of this embodiment are both cylinders, which have a simple structure, are easy to install and use, and have high control accuracy, so that the cylinder can accurately control the rotation angle of the turning frame 2. The cylinder body of the cylinder is hinged on the base 1, and the piston rod of the cylinder is hinged to the bottom of the corresponding turning frame 2. In other embodiments, the two driving members can also be oil cylinder push rods or electric cylinder push rods.

[0056] like Figure 1 As shown, the turning frame 2 includes a main frame 21, a first roller 22 and a third driving member, and one end of the main frame 21 is pivotally connected to the base 1. A plurality of first rollers 22 are arranged side by side along the length direction of the main frame 21 to form a first roller track, and both ends of the axial direction of each first roller 22 are pivotally connected to the main frame 21. The third driving member is connected to the plurality of first rollers 22 in a transmission manner to drive the plurality of first rollers 22 to rotate on the main frame 21. The third driving member drives the plurality of first rollers 22 to rotate, so that the first roller track on the turning frame 2 is a powered roller track, and the first roller track enables the object to be turned to slide into or out of the turning frame 2 in the left and right directions, greatly reducing the movement resistance of the turning frame 2 to be turned, and improving the turning efficiency. It should be noted that the first roller 22 can rotate counterclockwise or clockwise, so that the object to be turned has two moving directions on the first roller track, that is, from left to right or from right to left.

[0057] In this embodiment, the flip frame 2 on the left side of the base 1 is the first flip frame, and the flip frame on the right side of the base 1 is the second flip frame. The two flip frames 2 are installed side by side on the base 1 in the left-right direction. And the right end of the first flip frame and the left end of the second flip frame are both pivotally connected to the base 1. In this embodiment, the two flip frames 2 can reciprocate within the range of 0° to 90°. When the flip frame 2 does not rotate, the flip frame 2 is in the initial position (i.e., horizontal state), and the flip frame 2 is parallel to the base 1. When the flip frame 2 rotates 90° from the initial position, the flip frame 2 is in a vertical state, and the flip frame 2 is perpendicular to the base 1. Two support columns 11 arranged at intervals along the front-back direction are installed on both left and right ends of the base 1. When the first flip frame is in the initial position, the two support columns 11 at the left end support the first flip frame so that the first flip frame is kept in a horizontal state; when the second flip frame is in the initial position, the two support columns 11 at the right end support the second flip frame so that the second flip frame is kept in a horizontal state.

[0058] For ease of understanding, now combined Figure 2 and Figure 3 The flipping process of the flipping device is described in detail: the four sides of the box body are defined as the first side, the second side, the third side and the fourth side. Figure 2 As shown, the first flip frame is in the initial position, that is, the first flip frame is parallel to the base 1, and the second driving member 4 drives the second flip frame to move along Figure 2 Rotate in the direction indicated by the middle arrow to a vertical state, at which point the first flip frame and the second flip frame form a 90° angle and form a bracket. Place the box on the first flip frame and lean against the second flip frame, so that the first flip frame supports the first side surface of the box (the bottom surface of the box at this time), the second side surface of the box leans against the second flip frame, and the third side surface is the top surface of the box at this time. The first driving member 3 drives the first flip frame to rotate, while the second driving member 4 drives the second flip frame to rotate synchronously, so that the first flip frame and the second flip frame always maintain a bracket structure. Figure 3 As shown, when the bracket rotates 90°, the first flip frame moves along Figure 3 The first flip frame is rotated to a vertical state in the direction indicated by the middle arrow, that is, the first flip frame is perpendicular to the base 1, and the second flip frame is rotated to the initial position, that is, the second flip frame is in a horizontal state and parallel to the base 1. At this time, the second side surface of the box is the bottom surface, and the fourth side surface is the top surface, and the box is flipped 90°. When the box needs to be flipped further, the first flip frame is first returned to the initial position, and then the box is translated to the first flip frame. Repeating the above flipping action can realize 180°, 270° and 360° flipping of the box, which will not be repeated here.

[0059] like Figure 4As shown, the flipping device also includes a carrier 5 and a smooth bar 6 (i.e., an aluminum alloy slide rail), and the carrier 5 is used to support and transport the piece to be flipped. The carrier 5 is provided with a smooth bar 6 along the length direction, and the piece to be flipped can slide in or out of the carrier 5 on the smooth bar 6. The carrier 5 supports the piece to be flipped, which facilitates the movement and transportation of the piece to be flipped. At the same time, two smooth bars 6 spaced apart in the front-to-back direction are installed on the carrier 5, so that the piece to be flipped can slide on the smooth bar 6, reducing the movement resistance of the frame 2 to be flipped on the carrier 5 and improving the flipping efficiency. Since the smooth bar 6 is a mature product, it can be installed on the carrier 5 as a whole through external purchase, which reduces the cost of the carrier 5.

[0060] Furthermore, the carrier 5 is provided with a limit groove 51 along the length direction, and the smooth bar 6 can be installed in the limit groove 51 in a liftable manner. A lifting assembly is installed on the carrier 5, and the lifting assembly is transmission-connected with the smooth bar 6 to drive the smooth bar 6 to rise and protrude from the upper surface of the carrier 5 or to descend into the limit groove 51. By lifting and lowering the smooth bar 6, the part to be flipped can be flush with the flip frame 2, so that the part to be flipped can slide smoothly onto the flip frame 2. The third driving member of this embodiment is a cylinder, which has a simple structure, is easy to install and use, and has a high control accuracy, so that the lifting height of the smooth bar 6 can be accurately controlled by the cylinder. In other embodiments, the third driving member can also be a cylinder push rod or an electric cylinder push rod.

[0061] When the part to be flipped is placed on the carrier 5, the smooth bar 6 is located in the limiting groove 51. When the first flip frame and the second flip frame form a bracket, the carrier 5 is placed on the left side of the base 1 and adjacent to the left end of the base 1. The lifting assembly lifts the smooth bar 6 to the upper surface of the protruding carrier 5, so that the bottom surface of the part to be flipped is flush with the upper surface of the first flip frame, and then pushes the part to be flipped to slide from left to right on the smooth bar 6 to the first flip frame. The third driving member drives the first roller 22 of the first flip frame to rotate, so as to drive the part to be flipped to move on the first flip frame until one side of the part to be flipped abuts against the second flip frame in a vertical state.

[0062] Furthermore, if Figure 4As shown, the upper surface of the platform 5 is concave to form a guide groove 52, and the guide groove 52 extends along the length direction of the platform 5 and passes through one end of the length direction of the platform 5 to form a loading and unloading port. By setting the guide groove 52, it is convenient to transport the parts to be flipped. Since the transfer forklift generally has two forks, two guide grooves 52 are arranged on the platform 5 along the front and rear directions, and the two guide grooves 52 have two loading and unloading ports on the left side of the platform 5. When the transfer forklift supports the parts to be flipped and moves to the top of the platform 5 through the two forks, the two forks are lowered into the two guide grooves 52 until the parts to be flipped are lowered to the upper surface of the platform 5, and the forks continue to descend in the guide grooves 52 until they are separated from the parts to be flipped, and then the forks are pulled out from the loading and unloading port. When it is necessary to fork up the parts to be flipped, it is only necessary to extend the fork arm into the guide groove 52 from the loading and unloading port, and then the fork arm is raised and supports the parts to be flipped on the platform 5, and finally the parts to be flipped are transported to the next station.

[0063] Furthermore, the flipping device also includes a control module, and the driving assembly and the third driving member are electrically connected to the control module, so that the driving assembly and the third driving member are automatically controlled by the control module, thereby realizing automatic control of the flipping process. In addition, a detection element such as a photoelectric sensor switch or a proximity switch can be installed on the base 1 to accurately detect the rotation angle of the flip frame 2, etc., so as to realize the automatic flipping operation of the part to be flipped.

[0064] It should be noted that the flipping device also includes a roller frame and a second roller, and the roller frame is located between the platform 5 and the base 1. A plurality of second rollers are arranged side by side along the length direction of the roller frame to form a second roller track, and both ends of the axial direction of each second roller are pivotally connected to the roller frame, so that the second roller track on the roller frame is an unpowered roller track. The second roller track can reduce the movement resistance of the flipping frame 2, and the part to be flipped will not move on the second roller track when there is no external force. When the flipping frame 2 adopts a powered roller track, an unpowered roller track is added between the flipping frame 2 and the platform 5. When the part to be flipped moves from the powered roller track to the unpowered roller track, the flipping frame 2 will not move forward (left and right in the figure) when there is no external force, thereby avoiding the safety risk of the part to be flipped on the platform 5 to the surrounding personnel due to the continuous movement, thereby improving the safety of the flipping process.

[0065] like Figure 5 As shown, this embodiment also proposes a flipping method, and the flipping device flips the object to be flipped through the flipping method. The flipping method includes the following steps:

[0066] S1: The first turning frame is parallel to the base 1, and the driving assembly drives the second turning frame to rotate until the two turning frames 2 form a bracket.

[0067] S2: The part to be flipped is placed in the bracket.

[0068] S3: The driving assembly drives the bracket to rotate until the second flip frame is parallel to the base 1.

[0069] S4: The driving assembly drives the first turning frame to rotate until the first turning frame is parallel to the base 1 .

[0070] S5: Push the turned piece to be turned out of the turning frame 2.

[0071] The above-mentioned flipping device flips the workpiece to be flipped through the flipping method of the flipping device, thereby improving the flipping efficiency of the workpiece to be flipped. At the same time, there is no need for manual flipping by operators, which not only reduces the workload of the staff, but also avoids damage to the workpiece to be flipped and the operators during the flipping process, thereby improving the safety of the flipping process.

[0072] It should be noted that the flipping method further includes step S6: repeating steps S1 to S5 according to different flipping angles of the part to be flipped. When the part to be flipped is flipped 90° after the above steps S1 to S5, when it is necessary to flip the part to be flipped 180°, first return the first flip frame to the initial position, then translate the box body to the first flip frame, and repeat steps S1 to S5, so that the part to be flipped is flipped from the bottom surface to the top surface. It can be understood that each time steps S1 to S5 are repeated, the part to be flipped will flip 90°, and steps S1 to S5 can be repeated multiple times according to different flipping angles of the part to be flipped. For example, when the part to be flipped is flipped 180°, steps S1 to S5 are repeated once, when the part to be flipped is flipped 270°, steps S1 to S5 are repeated twice, and when the part to be flipped is flipped 360°, steps S1 to S5 are repeated three times.

[0073] In this embodiment, before step S1, a platform 5 is placed on the side of the base 1 with the first flip frame, and the workpiece to be flipped is placed on the platform 5. In step S5, the flipped workpiece to be flipped is pushed back onto the platform 5. When the production line of the box is a fixed-point operation, that is, the box needs to be returned to the platform 5 on the left to complete the processing operation, after completing step S5, the box is pushed back from right to left onto the platform 5 on the left side of the base 1, and the side of the box located at the bottom is flipped to the top, so that the top side of the box (the side originally located at the bottom) can be fully welded on the platform 5 and other corresponding auxiliary parts can be assembled and welded.

[0074] Furthermore, in step S5, another carrier 5 is placed on the side of the base 1 with the second flip frame, and the flipped part to be flipped is pushed onto the other carrier 5. When the production line of the box is an assembly line operation, another carrier 5 is set on the right side of the base 1 to carry the flipped box, and the flipped box is moved to the carrier 5 on the right side. The operator performs full welding on the top side (the side originally located at the bottom) of the box on the carrier 5 on the right side and assembles and welds other corresponding accessory parts.

[0075] It should be noted that a roller frame of an unpowered second roller conveyor may be installed between the left platform 5 and the left side of the base 1 and between the right side of the base 1 and the right platform 5 to improve the safety of the flipping process.
