The described embodiment is a contact part embodiment of the utility model, not all embodiments.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see attached Figure 1-4, the present embodiment provides a frame turning mechanism 10, which is used to turn over a frame such as a formation frame 20. It is understandable that the frame turning mechanism 10 in the present embodiment includes but is not limited to turning over the formation frame 20, and the turning object can also be a tray, a material frame, a cleaning frame, a transport frame, etc., which is not limited in the present embodiment. Taking the formation frame 20 as an example, positioning grooves, positioning holes, etc. can also be provided on both sides of the formation frame 20 to facilitate the frame turning mechanism 10 to clamp it.

[0035] The frame turning mechanism 10 comprises a first clamp 1 and a second clamp 2, the first clamp 1 and the second clamp 2 are arranged opposite to each other, and the two sides of the formation frame 20 are clamped by the first clamp 1 and the second clamp 2. The first clamp 1 comprises a first clamping rod 110 and a first driving assembly 120, and the first driving assembly 120 is connected to the first clamping rod 110 in a transmission manner so that the first clamping rod 110 rotates; the second clamp 2 comprises a second clamping rod 210 and a follower assembly 220, and the follower assembly 220 is connected to the second clamping assembly, and the second clamping rod 210 can be rotated by the follower assembly 220. The first clamping rod 110 and the second clamping rod 210 can be clamping claws, suction cups, clamping rods, etc., and one side of the formation frame 20 is clamped.

[0036] The first drive assembly 120 is used for driving the first clamping rod 110 to rotate, and the first drive assembly 120 can be an electric motor, a motor, a cylinder, etc., and those skilled in the art can set it voluntarily, and only need to make it drive the first clamping rod 110 to rotate. Exemplary, the first drive assembly 120 comprises a synchronous wheel 121, a synchronous belt 122 and a rotation drive member 123, and the first clamping rod 110 is connected with the synchronous wheel 121, and the synchronous belt 122 is sleeved on the synchronous wheel 121, and the rotation drive member 123 is connected with the synchronous belt 122, and the rotation drive member 123 can be a motor. During use, the driving motor drives the synchronous belt 122 to move, drives the synchronous wheel 121 by the synchronous belt 122, and then drives the first clamping rod 110 to rotate, and completes the overturning of the first side of the formation frame 20.

[0037] Follower assembly 220 rotates the second clamping rod 210, wherein, follower assembly 220 can be motor, follower wheel, bearing etc. Exemplary, follower assembly 220 is a motor, and motor is by systems such as belt drive, gear transmission or directly connected with second clamping rod 210 transmission, so that second clamping rod 210 is rotated.Preferably, its rotation speed is identical with first drive assembly 120, drives both sides of formation frame 20 to rotate simultaneously, formation frame 20 is overturned, this setting mode has high working efficiency, and dual drive can adapt to the larger framework of quality, by the rotation angle driven by control motor etc., formation frame 20 can also be made to stay on different angles. Exemplary, follower assembly 220 is a bearing, by bearing, second clamping rod 210 can be passively rotated, when first drive assembly 120 drives first clamping rod 110 to rotate, it can transfer power to second clamping rod 210 along formation frame 20, at this moment, second clamping rod 210 rotates, completes the overturning of formation frame 20. This arrangement can simplify the structure, reduce production costs, and reduce energy consumption, and is suitable for frames of lower quality.

[0038] In certain embodiments, the first fixture 1 also includes the first connecting rod 130, the first clamping rod 110 is arranged on one end of the first connecting rod 130, the second fixture 2 includes the second connecting rod 230, the follower assembly 220 includes an axle body 221, and the second clamping rod 210 is movably arranged on one end of the second connecting rod 230 by the axle body 221. The first connecting rod 130, the second connecting rod 230 are vertically arranged, and space is reserved for the flipping of the formation frame 20. Exemplary, the second clamping rod 210 is provided with an axle body 221 on a side facing the second connecting rod 230, and is movably connected with the second connecting rod 230 by the axle body 221. In use, when the first driving assembly 120 drives the formation frame 20 one side to rotate, because the second clamping rod 210 is movably connected with the first clamping rod 110, the formation frame 20 other side now rotates synchronously, and the flipping action to the formation frame 20 is completed.

[0039] During use, the two sides of the formation frame 20 are first clamped and fixed by the first clamping rod 110 and the second clamping rod 210. At this time, the first driving assembly 120 drives the first clamping rod 110 to rotate, and the follower assembly 220 drives the second clamping rod 210 to rotate, thereby driving one side of the formation frame 20 to rotate, and completing the flipping of the formation frame 20. The flipping angle is not limited here, and those skilled in the art can set it according to actual needs.

[0040] The present embodiment can overturn the formation frame 20 by arranging the first clamp 1 and the second clamp 2.Wherein, the first clamping rod 110 and the second clamping rod 210 clamp the formation frame 20 both sides, the first drive assembly 120 and the follower assembly 220 drive the first clamping rod 110 and the second clamping rod 210 to rotate, and the follower assembly 220 can be set to active drive form or passive drive form, can make it adapt to different sizes, the framework of type, improve the universality of equipment.Can reduce the dependence on manual operation by automatic overturning, save cost, and it can make the overturning angle more accurate by the modes such as external program control, improve production efficiency, eliminate the potential safety hazard brought by manual overturning.

[0041] Example 2

[0042] The difference between Example 2 and Example 1 is that the present embodiment further optimizes the follower component 220 in the frame flipping mechanism 10. Figure 2-3 As shown, in some embodiments, the shaft body 221 is arranged on one side of the second clamping rod 210, and the follower assembly 220 also includes a cam 222 and a limit unit 223, the cam 222 is provided with a limit slot 222a, the cam 222 is connected to the shaft body 221, the limit unit 223 includes a limit rod 223a, a guide member 223b and a limit driving member 223c, the guide member 223b is arranged on the second connecting rod 230, the limit rod 223a is movably connected with the guide member 223b, and the limit driving member 223c is transmission-connected with the limit rod 223a to drive the limit rod 223a to abut against the limit slot 222a. Specifically, guide member 223b is arranged along the direction of cam 222, and guide member 223b can be a guide rail, and limit rod 223a is connected with a slide block, and the slide block is slidably connected on the guide rail, and limit rod 223a moves along the direction of guide member 223b, so that limit rod 223a can abut against cam 222. Limit drive 223c can be a cylinder, an electric cylinder, etc., which can drive limit member to move. After formation frame 20 flips to the preset position, at this moment, the limit groove 222a on cam 222 also rotates to the preset position, and limit drive 223c drives limit rod 223a to move, so that it is inserted in the limit groove 222a, cam 222 is limited, and then the second clamping rod 210 is limited, so that it can not rotate, and in the subsequent work process, formation frame 20 deflects, improves the stability of equipment.

[0043] Furthermore, the limiting driving member 223c is a spring, and at least two limiting grooves 222a are provided on the cam 222; one end of the spring is connected to the second connecting rod 230, and the other end is connected to the limiting rod 223a. At least two limiting grooves 222a correspond to the starting position and the preset position of the rotation of the second clamping rod 210 respectively. The end of the limiting rod 223a and the limiting groove 222a can be chamfered to make the limiting rod 223a easier to move under the action of force in subsequent work. Under the initial state, the limiting rod 223a is in the limiting groove 222a of the initial position, when the first driving assembly 120 drives the formation frame 20 to rotate, at this moment, the formation frame 20 drives the second clamping rod 210 to rotate, and the cam 222 rotates, and the limiting rod 223a moves along the inner wall of the limiting groove 222a, and the spring is compressed, and the limiting rod 223a rises, and at this moment, because the spring is compressed, the limiting rod 223a abuts against the outer edge of the cam 222. After the formation frame 20 flips to the preset angle, at this moment, the cam 222 rotates to the preset position, and the limiting groove 222a of the preset position rotates into place, and the spring drives the limiting rod 223a to move down, and the limiting rod 223a is moved down into the limiting groove 222a, and fixation is completed. This setting can complete automatic limiting to the frame body turnover mechanism 10 by arranging a spring, and compared to the driving such as the cylinder, the design is simpler, and the formation frame 20 can be effectively prevented from preventing the occurrence of deflection after rotating into place.

[0044] In some embodiments, a cam 222 follower is provided on one end of the limiting rod 223a facing the cam 222, and the limiting rod 223a abuts against the cam 222 through the cam 222 follower. The cam 222 follower can make it easier for the limiting rod 223a to disengage from or enter the limiting groove 222a, effectively reducing friction, preventing the cam 222 from being damaged during the movement of the limiting rod 223a along the outer edge of the cam 222, and improving the service life of the device.

[0045] In some embodiments of the present application, the follower assembly also includes a photoelectric sensor for detecting whether the cam is reset. Furthermore, the photoelectric sensor is a slot-type photoelectric sensor, which can be a slot-shaped photoelectric sensor formed by installing a light emitter and a receiver face to face on both sides of a slot. The light emitter can emit infrared light or visible light, and the light receiver can receive the light without obstruction. However, when the object to be detected passes through the slot, the light is blocked, and the photoelectric switch is activated to output a switch control signal to cut off or connect the load current, thereby completing a control action. Detecting whether the cam is reset and feeding back the data to an external automated control system can achieve safe and stable flipping operations, reduce the probability of accidents, and ensure safety in the production process.

[0046] In some embodiments, the first clamping rod 110 and the second clamping rod 210 are provided with positioning pins 4 for positioning the formation frame 20. The number of the positioning pins 4 is set according to actual conditions, and the formation frame 20 can be positioned.

[0047] Example 3

[0048] The difference between Example 3 and Example 1 is that this example further optimizes the frame flipping mechanism 10. Figure 1 As shown, further, it also includes a second driving component 5, which is connected to the first clamp 1 and the second clamp 2 in a transmission manner to drive the first clamp 1 and the second clamp 2 to move closer or farther away. The second driving component 5 can be a switch clamp cylinder, a pneumatic finger, a mobile module, etc., and its driving end is respectively connected to the first clamp 1 and the second clamp 2 to drive the first clamp 1 and the second clamp 2 to move closer or farther away from each other, so that it can adapt to frames of different lengths and widths, thereby improving the universality of the device.

[0049] In some embodiments, a third drive assembly is further included, and the third drive assembly is transmission-connected with the transmission members of the first fixture 1 and the second fixture 2 to drive the first fixture 1 and the second fixture 2 to move along the lateral direction of the formation frame 20. The third drive assembly can be a cylinder, a linear guide rail, etc., and two third drive assemblies can be provided, which are respectively connected to the first fixture 1 and the second fixture 2 to drive the first fixture 1 and the second fixture 2 to move along the lateral direction of the formation frame 20, so as to facilitate positioning thereof, so that the fixture can fix the formation frame 20.

[0050] Example 4

[0052] During use, the mobile module drives the frame flipping mechanism to move through a manipulator and other equipment, and moves it to the vicinity of the formation frame 20. The frame flipping mechanism starts to work, first fixing the formation frame 20, and then the mobile module drives the frame flipping mechanism to rise to a certain height. The frame flipping mechanism flips the formation frame 20. After flipping into place, the next step is carried out.
