[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] The utility model provides a turning device, aiming to solve the problem that the mechanical arm in the prior art has poor bearing capacity and is difficult to turn over workpieces of larger volume or mass. Figures 1 to 8The turning device includes: a frame; a turning frame 1, on which a workpiece is carried; a driving device 7, arranged on the frame, and the driving device 7 drives the turning frame 1 to rotate along the axis of the turning frame 1; a first guide wheel mechanism 2, arranged on the frame, and the first guide wheel mechanism 2 includes at least two main guide wheels for carrying the turning frame 1, and the main guide wheels are abutted and supported against the outer side of the turning frame 1; a second guide wheel mechanism 3, arranged on the frame, and the second guide wheel mechanism 3 includes a guide wheel, and the guide wheel is abutted against the inner side of the turning frame 1. There is a turning frame 1 above the frame (not shown in the figure), and the turning frame 1 is used to carry the workpiece that needs to be turned over. Above the frame, a driving device 7 is arranged on the outside of the turning frame 1. The driving device 7 drives the turning frame 1 to rotate along its own axis. A first guide wheel mechanism 2 and a second guide wheel mechanism 3 are also arranged on the frame, wherein the first guide wheel 2 includes at least two main guide wheels, which abut against the outside of the turning frame 1 to carry the turning frame 1, and at the same time, the turning frame 1 rolls relative to the main guide wheel during rotation. The second guide wheel mechanism 3 includes a coaching wheel, which abuts against the inside of the turning frame 1, and the force applied by the main guide wheel to the turning frame 1 is directed to its axis, while the force applied by the coaching wheel to the turning frame 1 is directed to the outside of the turning frame 1. Through support in multiple directions, the turning frame 1 is more stable during the turning process and the turning action is smoother.

[0041] Through this embodiment, by carrying the workpiece inside the flip frame, the flip frame is driven to rotate by a driving device, and a main wheel is arranged on the frame to abut the outside of the annular structure and used to carry the rolling frame, and a guide wheel is arranged on the frame to abut the inside of the flip frame. When the flip frame rotates to flip the workpiece, the flip device has support points in multiple directions and angles, has the ability to carry workpieces of larger volume and mass, and can smoothly flip workpieces of larger volume or heavier weight.

[0042] In one embodiment, referring to Figure 1 , 4 5, the flip frame 1 includes a linkage 14 and a plurality of flip rings, the plurality of flip rings are coaxially arranged, the driving device 7 drives one of the flip rings to rotate, and the linkage 14 connects the plurality of flip rings to drive the plurality of flip rings to rotate synchronously. The flip frame 1 is composed of a plurality of flip rings arranged at intervals along its axial direction, and the plurality of flip rings are connected by the linkage 14 to form a whole. The use of a plurality of flip rings and the linkage 14 to form a cage structure together can increase the structural stability of the flip frame 1. By driving one of the flip rings to rotate through a driving device 7, the entire flip frame 1 can be driven to rotate together to achieve synchronous rotation. In actual use, according to the different number of workpieces that need to be flipped at a time and the different lengths of the workpieces, multiple flip rings will be selected for extended arrangement to increase the axial length of the flip frame, so as to adapt to the working conditions of different assembly lines.

[0043] Further, refer to Figure 1 ,4 5, the linkage 14 includes a first connecting frame 141 and a second connecting frame 142 arranged at intervals along the axial direction of the flip frame 1, and the first connecting frame 141 and the second connecting frame 142 are respectively connected to the inner side and / or the outer side of the plurality of flip rings. The first flip ring 11 and the second flip ring 12 are respectively placed at the front and rear ends of the device. As the main components for performing the flipping action, they are arranged at the outermost side to ensure the structural stability of the device. The first connecting frame 141 and the second connecting frame 142 are arranged symmetrically, which can ensure that the center of gravity coincides with the center of mass when the flip frame 1 rotates, so that the vibration caused by the rotation is smaller. The first flip ring 11 and the second flip ring 12 and the first connecting frame 141 and the second connecting frame 142 form a cage-shaped flip frame 1, wherein the first connecting frame 141 and the second connecting frame 142 can be connected to the inner side of the first flip ring 11 and the second flip ring 12 or to the outer side of the first flip ring 11 and the second flip ring 12, and the specific connection depends on the size of the workpiece to be processed. Through the above structure, the flip frame 1 can be flipped stably while reducing the weight of the flip frame 1 as much as possible, so that the driving device 7 reduces invalid work when rotating the flip frame 1 and the workpiece to be flipped therein, reduces the energy consumption of the whole machine, and improves the flipping speed of the flip frame 1, so that the flipping device of the utility model is more energy-saving and efficient.

[0044] In one embodiment, referring to Figure 1 , 4 , 5 and 6, at least one of the flip rings is provided with a bearing track along its outer circumference, and there are two main guide wheels, namely, a first main guide wheel 21 and a second main guide wheel 22, and the bearing track abuts against the first main guide wheel 21 and the second main guide wheel 22. A first bearing track 111 is arranged on the outer side of the first flip ring 11 near the end of the axis of the flip frame 1, and a second bearing track 121 is arranged on the outer side of the second flip ring 12 near the end of the axis of the flip frame 1. The first bearing track 121 abuts against the first main guide wheel 21 and the second main guide wheel 22, and the second bearing track 121 abuts against the first main guide wheel 23 and the second main guide wheel 24. Both sides of the first bearing track 11 and the second bearing track 12 are provided with protruding blocking structures, and when the main guide wheels are running in the bearing track, the sliding between the main guide wheels and the track along the axis direction will be blocked and thus restricted. At the same time, the entire turning frame 1 is supported by four main guide wheels divided into two groups, which respectively abut against the first load-bearing rail 111 and the second load-bearing rail 121. The four guide wheels are fixed on their own main guide wheel brackets 25, and the main guide wheel brackets 25 are connected to the frame. The above structure provides four contact fulcrums on the outside of the turning frame 1 to form a supporting plane, so that the turning frame 1 can turn more smoothly.

[0045] In one embodiment, referring to Figure 1 , 2and 3, the inner side of at least one flip ring abuts against at least two training wheels. The first training wheel 31 and the second training wheel 32 abut against the inner side of the first flip ring 11, and the third training wheel 33 and the fourth training wheel 34 abut against the inner side of the second flip ring 12. The above four training wheels together constitute the second guide wheel mechanism 3. The four guide wheels are mounted on their respective training wheel brackets 35, and the training wheel brackets 35 are mounted on the frame. Since the flip frame 1 or the flip ring itself has its own weight and also carries a workpiece, the flip ring may become elliptical due to the influence of gravity during its rotation, affecting the accuracy of rotation and causing damage to parts. Therefore, multiple training wheels are arranged on the inner side of the flip ring to abut against the inner surface of the flip ring and apply a certain pressure to ensure the roundness of the flip ring, so that the flip frame 1 can operate more stably and the flip device can be more durable.

[0046] In one embodiment, referring to Figure 1 , 4 , 5 and 6, the turning frame 1 is provided with a driving track 112 along its outer peripheral side, the driving device 7 includes a motor 71 and a driving wheel, the motor 71 drives the wheel to rotate, and the driving wheel cooperates with the driving track 112 to drive the turning frame 1 to rotate. Next to the first bearing track 111 outside the first bearing track 11, a driving track 112 is arranged adjacently, the driving device 7 includes a motor 71 for providing power and a driving wheel installed at the front end of the motor for outputting power, the driving wheel and the driving track 112 can be gear-driven, chain-driven or belt-driven, etc., and the specific transmission mode depends on the quality of the turning frame 1 and the workpiece to be turned.

[0047] Further, the driving wheel is a sprocket 72, and a toothed chain (not shown in the figure) is arranged on the driving track 112, and the sprocket 72 is meshed with the toothed chain for transmission. A motor 71 is installed on the frame, and a sprocket 72 is installed on the output shaft of the motor 71. A driving track 112 is arranged at a position close to the sprocket 72 and the first flip ring 11, and a toothed chain is arranged on the driving track 112. The toothed chain and the sprocket 72 are meshed, and the motor 71 can drive the first flip ring 11 to rotate when outputting power to the outside. A toothed chain is fixed on the driving track 112, and a sprocket 72 is installed on the front output shaft of the motor 71. The output power of the motor drives the sprocket 72 to rotate, thereby driving the toothed chain to drive the first flip ring 11 to rotate, and the flip frame 1 rotates. The transmission method using chain drive can make the flipping movement of the flipping device smoother and less prone to vibration. It also has the advantages of easy maintenance and lower maintenance cost.

[0048] In one embodiment, referring to Figure 1 , 2and 3, further comprising a transport mechanism 4, which is arranged on the inner side of the turning frame 1, and the transport mechanism 4 is arranged along the axis direction of the turning frame 1, and the transport mechanism 4 is used to carry and drive the workpiece to be transported along the axis direction of the turning frame 1. The transport mechanism 4 can be a power roller or a belt drive, which is arranged along the axis direction of the turning frame 1 to connect the upstream and downstream stations of the turning device, thereby realizing the transmission of the workpiece. Through the transport mechanism 4, the loading and unloading of materials can be fully automated when the turning device is working, without manual intervention, thereby improving the operation efficiency of the assembly line.

[0049] In one embodiment, referring to Figure 1 , 2 The transport mechanism 4 includes a first transport component 41 and a second transport component 42, which are symmetrically arranged along the axis of the flip frame 1. The number of transport components to be arranged is actually determined according to the workpiece that needs to be flipped by the flipping device. If the workpiece needs to be flipped 180 degrees, the first transport component 41 and the second transport component 42 are symmetrically arranged along the axis, so that the workpiece can be automatically fed by the first transport component 41. After the workpiece flipping action is completed, the second transport component 42 transports the flipped workpiece out of the flipping device, and there is no need to add a device to adjust the height of the workpiece to adapt it to the height of the downstream assembly line. If the workpiece needs to be flipped 120 degrees, three transport components can be symmetrically arranged along the axis, and so on. The use of the above-mentioned corresponding number of transport components symmetrically arranged along the axis according to the flipping angle of the workpiece can improve the degree of automation of the flipping device on the entire assembly line and improve the operation efficiency of the assembly line.

[0050] In one embodiment, referring to Figure 1 , 2 , 3, 6 and 7, the turning device disclosed in the utility model also includes a pressing mechanism 5, the transport mechanism 4 includes a first transport component 41, the first transport component 41 is arranged on the inner side of the turning frame 1, the pressing mechanism 5 is arranged on the inner side of the turning frame 1 and is spaced apart from the first transport component 41 along the radial direction of the turning frame 1, and the pressing mechanism 5 is used to move along the radial direction of the turning frame 1 to press toward the first transport component 41. In order to make the process of turning the workpiece safer and prevent the workpiece from falling off or sliding during the turning process, causing unnecessary workpiece processing loss, the pressing mechanism 5 is arranged on the inner side of the turning frame 1, and the first transport component 41 is arranged in the direction close to the axis of the turning frame 1, and the second transport component 42 is arranged on the other side symmetrically with the axis, and the pressing mechanism 5 pushes the first transport component 41 to move toward the second transport component 42 to achieve clamping of the workpiece, so that the static friction between the first transport component 41 and the transport component is sufficient to overcome gravity during the turning process, so that there will be no problems of slipping and falling off during the turning process.

[0051] Further, refer to Figure 1 , 2and 3, the transport mechanism 4 also includes a second transport component 42, the second transport component 42 is connected to the side of the pressing mechanism 5 close to the first transport component 41, the pressing mechanism 5 drives the second transport component 42 to press toward the first transport component 41, so that the first transport component 41 and the second transport component 42 jointly clamp the workpiece and transport it along the axial direction of the flip frame 1. The pressing component includes a first pressing component 51 and a second pressing component 52, the transport component includes a first transport component 41 and a second transport component 42, the first transport component 41 and the second transport component 42 are symmetrically arranged around the axis of the flip frame 1, the first pressing component 51 is arranged on the outside of the first transport component 41, and the second pressing component 52 is arranged on the outside of the second transport component 42, the first pressing component 51 and the second pressing component 52 respectively drive the first transport component 41 and the second transport component 42 to make linear motion along the radial direction of the flip frame 1. During actual use, when the flipping device is in the initial state, the first transport component 41 is located below the axis, and the second transport component 42 is located above the axis. The workpiece is fed into the flipping device, and the downward surface of the workpiece contacts the inner surface of the first transport component 41. The first pressing component 51 and the second pressing component 52 press the first transport component 41 and the second transport component 42 respectively, and the inner surface of the second transport component 42 contacts the upward surface of the workpiece. The driving device 7 drives the flipping frame 1 to flip. After rotating 180 degrees, the first pressing component 51 and the second pressing component 52 return to the position before pressing, and the second transport component 42 operates to transport the workpiece to the downstream assembly line position.

[0052] In one embodiment, referring to Figure 1 , the transport assembly includes a plurality of belt lines 43 arranged end to end along the axis direction. Arranging multiple sections of transport units such as belt lines 43 or power roller axes on the transport assembly can allow the flipping device to play a certain workpiece stacking buffer function when feeding and discharging workpieces, which can reduce the arrangement of stacking buffer devices on the assembly line, shorten the length of the assembly line, and thus improve the operation efficiency of the assembly line. In actual use, when the upstream feeds the workpiece, each section of the belt line 43 can be kept with a workpiece, without the need to fix the distance between the workpieces like a single long belt line 43. In the flipping device of the same length, using multiple belt lines 43 adjacent end to end can flip more workpieces at a time, and if the downstream station is already in an occupied state, the workpiece can be cached for the downstream station after flipping, and the workpiece inflow of the upstream station will not be affected. In the continuous movement of the belt line 43, the upstream belt line 43 will be emptied, and the workpiece will be stacked on the downstream belt line 43. This makes the entire assembly line have stronger speed control flexibility, providing more possibilities for further customization and diversification of the assembly line.

[0053] In one embodiment, referring to Figure 1 and 7The first pressing assembly 51 and the second pressing assembly 52 each include a plurality of linear motion devices 53. One linear motion device 53 drives at least one belt line 43. The linear motion device 53 includes a pressing electric cylinder 531, an optical axis 532, a sliding seat 533, and an axle seat 534. The moving head (not shown in the figure) of the pressing electric cylinder 531 is fixed to the transport assembly. The pressing electric cylinder 531 is fixed on the turning frame 1. The moving head is driven by the electric cylinder to drive the transport assembly to perform linear motion. The optical axis 532 is connected and fixed to the transport assembly through the axle seat 534. The sliding seat 533 is installed on the turning frame 1. Through the guiding effect of the optical axis 532, the stability of the operation of the transport assembly can be guaranteed when it performs linear motion. One linear motion device 53 drives at least one belt line 43

[0054] In one embodiment, referring to Figure 1 and 7 , one linear motion device 53 drives at least one belt line 43. When one linear motion device 53 is connected to multiple belt lines 43 at the same time, segmented single pressing for different products can be achieved, so that the flip device can be applied to the production line for mixed processing of multiple types of workpieces.

[0055] In one embodiment, referring to Figure 1 and 8 The turning device disclosed in the utility model also includes a limiting mechanism 6. The limiting structure includes a side grid frame 61, which is arranged on the left and right sides of the first transport component 41 and the second transport component 42. A guiding structure 62 is provided on the side grid frame 61. The guiding structure 62 is arranged at the front and rear ends of the side grid frame 61. In order to make the workpiece continue to maintain its shape and position, and to overcome the inevitable deviation of the workpiece during the transportation of the workpiece by the transport component and the upstream transport device, a limiting mechanism 6 is provided to limit and guide the workpiece. The limiting structure includes a side grid frame 61, which is a plurality of grid plates arranged in parallel and extending along the axis direction of the shaft. The use of this structure can reduce its mass while maintaining the strength of the side grid frame 61, thereby reducing unnecessary work done by the driving device 7 when driving the turning frame 1. A guiding structure 62 is provided at the front and rear ends of the side grid 61 and the upstream and downstream positions of the upstream turning device. The guiding structure 62 is an inclined surface inclined toward the outside of the turning frame 1. When the workpiece is transported to the turning device on the assembly line, the inclined surface will guide the direction and position of the workpiece so that it enters the equipment in the correct position. When the workpiece completes the turning and enters the downstream station, the side of the workpiece is restricted by the side grid plate for lateral displacement, so that the position when entering the downstream station meets the requirements as much as possible, so as to reduce the number of correction devices for the downstream workpieces and shorten the process of the entire assembly line.

[0056] In one embodiment, the limiting mechanism 6 also includes an auxiliary motion mechanism, which is arranged on the outside of the limiting mechanism 6, and the auxiliary motion mechanism drives the limiting mechanism 6 to perform linear motion in the radial direction of the flip frame 1. An auxiliary motion mechanism is added to the outside of the side grid frame 61, and the side grid frame 61 is driven to perform linear motion by the auxiliary motion mechanism. The auxiliary pressing mechanism 5 and the transportation mechanism 4 further apply pressure to the workpiece and limit the position, further reducing the possibility of the workpiece being offset and falling during the flipping process. The first transportation component 41, the second transportation component 42 and the side grid frames 61 on both sides jointly fit the workpiece in a limiting manner, which can appropriately reduce the pressure output by the first pressing component 51 and the second pressing component 52 to the outside, thereby preventing some workpieces with appearance quality requirements or fragile workpieces from being damaged on their outer surfaces, and reducing the loss of workpieces during processing.

[0057] In one embodiment, the active guide wheel is made of a rigid material to ensure that the turning angle of the turning frame 1 does not deviate greatly, and the auxiliary guide wheel is made of an elastic material to further enhance its ability to provide support and shock absorption by pressing and abutting.

[0058] In one embodiment, the flipping device disclosed in the utility model further includes a sensor, a communication unit and a PLC. The flipping device can be arranged with a beam sensor, a pressure sensor, an angle sensor and a vibration sensor. The beam sensor can be arranged at both ends of the transport component to detect whether the workpiece on the transport component is in place. The pressure sensor can be arranged in the belt line 43 or between the transport component and the pressing component to detect whether the pressure provided by the pressing component is appropriate. The angle sensor can be arranged on the flip ring to detect whether the flip angle is correct. The vibration sensor is arranged on the frame to detect whether the mechanical vibration state of the equipment is suitable for work, so as to guide the assembly line operator to maintain and adjust the flipping device in time. Since some sensors on the flipping device need to flip together with the flip frame 1, there are limitations on the wired connection between the sensor and the PLC unit, so a communication unit is set to connect the PLC unit and the sensor through wireless communication. The sensor sends the acquired parameters to the PLC through the communication unit, and the PLC can be adjusted according to the preset program, and will also prompt the assembly line operator to intervene manually when necessary.

[0059] The utility model also provides an industrial assembly line, including the above-mentioned turning device. By arranging the above-mentioned turning device on the assembly line, compared with the assembly line that uses a mechanical arm to perform workpiece turning, it has a stronger turning ability of the workpiece's external dimensions and quality. At the same time, because the above-mentioned turning device has the function of stacking and caching, it can also shorten the overall length of the assembly line and reduce the layout site requirements of the entire assembly line. Especially for the production assembly line of large workpieces, shortening the length of the assembly line can make the assembly line operation more efficient.

[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
