[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0024] See also Figure 1 and Figure 2 , Figure 1 A three-dimensional structural diagram of a flipping mechanism according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 Enlarged structural diagram at A. A clamping assembly 10 provided in one embodiment of the present application is used to be installed on a first bracket 20, and the clamping assembly 10 includes: a first driving mechanism 11 and two swinging assemblies 12. The first driving mechanism 11 includes a servo electric cylinder 111, and the first driving mechanism 11 is arranged on the first bracket 20. Both swinging assemblies 12 are rotatable and spaced apart on the first bracket 20, and each swinging assembly 12 includes a clamping rod 121 for clamping a material 30. The first driving mechanism 11 is respectively connected to the two swinging assemblies 12, and the first driving mechanism 11 is used to drive each swinging assembly 12 to swing synchronously, so that the two clamping rods 121 are close to each other to clamp the material 30 or move away from each other to release the material 30.

[0025] It should be noted that the servo electric cylinder 111 is a modular product that integrates a servo motor and a lead screw. It converts the rotational motion of the servo motor into linear motion. At the same time, it converts the best advantages of the servo motor - precise speed control, precise rotational speed control, and precise torque control - into precise speed control, precise position control, and precise thrust control, thereby achieving high-precision linear motion.

[0026] In the clamping assembly 10, the first driving mechanism 11 drives each swinging assembly 12 to swing synchronously, so that the two clamping rods 121 can move closer to each other to clamp the material 30 or move away from each other to loosen the material 30. Since the first driving mechanism 11 in this embodiment includes a servo electric cylinder 111, the servo electric cylinder 111 acts on each swinging assembly 12 by linear pushing. After the swinging assembly 12 is pushed by the servo electric cylinder 111, the linear pushing action of the servo electric cylinder 111 can be converted into rotation. Among them, the servo electric cylinder 111 is a high-precision instrument that can more accurately control the speed and torque, so that the clamping degree of the two clamping rods 121 on the material 30 is flexible and controllable, and the material 30 can be prevented from being too loose or too tight, and the clamping force can be adjusted in time and accurately according to the properties of the material 30 and / or the thickness of the material 30, so that not only can the materials 30 of different thicknesses be stably clamped, but also the materials 30 can be prevented from being damaged.

[0027] See also Figure 1 and Figure 2 In some embodiments, the cross-sectional profile of the clamping rod 121 along its length direction includes but is not limited to regular shapes such as circles, ellipses, polygons, and other irregular shapes. It can be flexibly adjusted and set according to actual needs and is not limited here. As long as it can clamp the material 30 by tightly pressing against the side of the material 30 without causing puncture damage to the material 30, it can be used.

[0028] See also Figure 1 and Figure 2 In one embodiment, the clamping rod 121 includes a frame and an elastic material disposed on the frame, and the elastic material is used to abut against the material 30. Specifically, the elastic material can be a sleeve mounted on the frame, or an elastic body, for example, attached to the outer wall of the frame, etc., and can be flexibly adjusted and set according to actual needs, which is not limited here. The frame serves as a structural support, so that the overall structural rigidity of the clamping rod 121 is large enough to achieve stable clamping of the material 30; when the elastic material contacts the material 30, the damage to the material 30 can be reduced.

[0029] See also Figure 1 and Figure 2 In one embodiment, the swing assembly 12 further includes a rotating shaft 122 rotatably connected to the first bracket 20, and a first swing arm 123 and a transmission unit 124 respectively connected to the rotating shaft 122. The first swing arm 123 is also connected to the clamping rod 121, and the first driving mechanism 11 is connected to the transmission unit 124. In this way, when the first driving mechanism 11 is working, the transmission unit 124 is driven to operate, and the transmission unit 124 can drive the rotating shaft 122 to rotate accordingly. When the rotating shaft 122 rotates, the first swing arm 123 is driven to swing, and when the first swing arm 123 swings, it drives the clamping rod 121 to clamp or release the material 30.

[0030] See also Figure 1 and Figure 2 In some embodiments, the swing assembly 12 further includes a bearing 125 disposed on the first bracket 20. The rotating shaft 122 is rotatably disposed in the bearing 125. Thus, under the support of the bearing 125, the rotating shaft 122 can be stably rotated.

[0031] See also Figure 1 and Figure 2In one embodiment, the first driving mechanism 11 further includes a first pushing arm 112 connected to the servo electric cylinder 111. The transmission unit 124 includes a transmission shaft 1241 and a mounting seat 1242 fixedly connected to the rotating shaft 122. An axial hole is provided on the mounting seat 1242. The transmission shaft 1241 is movably inserted into the axial hole along its axial direction, and the transmission shaft 1241 is rotatably connected to the first pushing arm 112. In this way, when the first driving mechanism 11 drives the first pushing arm 112 to move back and forth, the first pushing arm 112 can synchronously drive the transmission shaft 1241 to rotate, and when the transmission shaft 1241 rotates, it can drive the mounting seat 1242 to rotate and move adaptively along the axial hole, and the mounting seat 1242 correspondingly drives the rotating shaft 122 to rotate, that is, it can realize the conversion of the linear motion of the first driving mechanism 11 into the rotational motion of the rotating shaft 122.

[0032] See also Figure 1 and Figure 2 In one embodiment, the transmission unit 124 further includes a wear-resistant sleeve 1243 disposed in the shaft hole. The transmission shaft 1241 is inserted into the wear-resistant sleeve 1243. In this way, the wear of the wear-resistant sleeve 1243 is small, the service life can be increased, the noise caused during the movement is reduced, and the movement accuracy is improved, so as to achieve stable clamping of membranes of different thicknesses.

[0033] In some embodiments, the wear-resistant sleeve 1243 includes but is not limited to a metal sleeve such as a copper sleeve, an aluminum sleeve, a stainless steel sleeve, or a non-metal sleeve such as a rubber sleeve, and the specific sleeve can be selected according to actual needs.

[0034] See also Figure 1 and Figure 2 In one embodiment, at least two first drive mechanisms 11 are provided, and at least two transmission units 124 are provided for each swing assembly 12. Each first drive mechanism 11 is respectively connected to each transmission unit 124 of one swing assembly 12, and each first drive mechanism 11 is also respectively connected to each transmission unit 124 of another swing assembly 12. In this way, when the clamping assembly 10 is working, each first drive mechanism 11 works synchronously, so that each swing assembly 12 is driven to move by at least two transmission units 124, thereby achieving stable clamping of the material 30.

[0035] Optionally, the number of the first driving mechanisms 11 includes but is not limited to two, three, four or more. In this embodiment, the number of the first driving mechanisms 11 is, for example, two, and the two first driving mechanisms 11 are respectively located on opposite sides of the first bracket 20. There are two transmission units 124 for each swing assembly 12, and they are respectively located at opposite ends of the rotating shaft 122. In this way, when the two first driving mechanisms 11 move synchronously and drive the two transmission units 124 of each swing assembly 12 to move, the two transmission units 124 of each swing assembly 12 act on the opposite ends of each rotating shaft 122, so that the rotating shaft 122 rotates stably, thereby enabling the clamping rod 121 to stably clamp the material 30. In addition, since the two first driving mechanisms 11 and the two swing assemblies 12 are located at opposite ends of the rotating shaft 122, the arrangement is reasonable and can avoid interference with the material 30.

[0036] Of course, in some embodiments, the number of first driving mechanisms 11 may also be one.

[0037] See also Figure 1 and Figure 2 In some embodiments, the length of the clamping rod 121 is ≥ 60% of the width of the material 30, for example 60%, 70%, 80%, 90%, 100%, 110%, etc. of the width of the material 30, so that the clamping rod 121 can press the material 30 more along the width direction W of the material 30, thereby achieving stable clamping of the material 30.

[0038] See also Figure 1 and Figure 2 In some embodiments, the rotating shaft 122 and the clamping rod 121 are independently arranged. Both can be arranged as a whole and, for example, extend from one side of the first bracket 20 to the other side of the first bracket 20. Alternatively, both can be arranged as multiple sections, and the first swing arm 123 is correspondingly arranged in multiple sections and connected in series to form a whole. Other structural forms can also be adopted.

[0039] See also Figure 1 and Figure 2 In a specific embodiment, the clamping rod 121 includes a plurality of clamping segments 1211 arranged in sequence and at intervals along the extension direction thereof. Each clamping segment 1211 is fixedly connected to the rotating shaft 122 through at least one first swing arm 123. In this way, the clamping rod 121 clamps the material 30 by means of each clamping segment 1211 synchronously abutting against the material 30. In addition, since the clamping rod 121 is provided with a plurality of clamping segments 1211 arranged in sequence and at intervals along the extension direction thereof, any two adjacent clamping segments 1211 are provided with an interval space, and can avoid the first bracket 20 to prevent interference.

[0040] Specifically, the rotating shaft 122 includes a plurality of shaft segments 1221 arranged in sequence and at intervals along the axial direction thereof. Each shaft segment 1221 is rotatably disposed on the first bracket 20. The opposite ends of each clamping segment 1211 are respectively connected to two adjacent shaft segments 1221 through the first swing arm 123, so that each shaft segment 1221 can be connected in series to form a whole.

[0041] See also Figures 1 to 4 , Figure 3 Shows Figure 1 Top view of the structure. Figure 4 Shows Figure 1 In one embodiment, a flip mechanism includes at least one clamping assembly 10 of any embodiment, and also includes a first bracket 20, a second driving mechanism 40 and a second bracket 50. The clamping assembly 10 is mounted on the first bracket 20, the second driving mechanism 40 is mounted on the second bracket 50, the second driving mechanism 40 is connected to the first bracket 20, and the second driving mechanism 40 is used to drive the first bracket 20 to rotate.

[0042] The above-mentioned flipping mechanism, because it is provided with a clamping assembly 10, before flipping the material 30, firstly, the material 30 is clamped by the clamping assembly 10, and then the second driving mechanism 40 is operated, and the second driving mechanism 40 drives the first bracket 20 to rotate, so that the material 30 can be flipped to a preset angle. Among them, since the first driving mechanism 11 in this embodiment includes a servo electric cylinder 111, the servo electric cylinder 111 acts on each swing assembly 12 in a linear push manner, and after the swing assembly 12 is pushed by the servo electric cylinder 111, the linear push action of the servo electric cylinder 111 can be converted into rotation. Among them, the servo electric cylinder 111 is a high-precision instrument, which can more accurately control the speed and torque, so that the clamping degree of the two clamping rods 121 on the material 30 is flexible and controllable, which can prevent the material 30 from being too loose or too tight, and can timely and accurately adjust the clamping force according to the properties of the material 30 and / or the thickness of the material 30, so that not only can the material 30 of different thicknesses be stably clamped, but also the material 30 can be prevented from being damaged.

[0043] See also Figures 1 to 4 In one embodiment, at least two clamping assemblies 10 are provided and arranged on the first bracket 20 in sequence and at intervals. Specifically, each clamping assembly 10 is arranged on the first bracket 20 in sequence and at intervals along the length direction L of the material 30. In this embodiment, there are two clamping assemblies 10, and the two clamping assemblies 10 are, for example, respectively located at the front and rear of the first bracket 20. In this way, the material 30 can be clamped at different positions along the length direction L of the material 30, so that the material 30 can be clamped stably and the material 30 can be prevented from loosening during the flipping process.

[0044] See also Figures 1 to 4 In one embodiment, the flipping mechanism further includes two conveying assemblies 60 arranged on the first bracket 20 at an interval from top to bottom. The conveying assembly 60 can drive the material 30 to move onto the first bracket 20 or drive the material 30 to leave the first bracket 20. In this way, the material 30 can be automatically loaded onto the first bracket 20, and the material 30 can be automatically unloaded, with high work efficiency. Specifically, before the flipping mechanism flips the material 30, the two conveying assemblies 60 perform a synchronous loading action, which can realize the material 30 being transported to the first bracket 20, and then the material 30 is clamped by the clamping assembly 10, and then the flipping mechanism completes the flipping action of the material 30, and then the clamping assembly 10 releases the material 30, and the two conveying assemblies 60 perform a synchronous unloading action, so that the material 30 leaves the first bracket 20.

[0045] See also Figure 2 In some embodiments, the conveying assembly 60 includes a third driving mechanism 61 disposed on the first bracket 20, a driving wheel 62 and a driven wheel 63 rotatably disposed on the first bracket 20, and a transmission element 64 connecting the driving wheel 62 and the driven wheel 63. The third driving mechanism 61 is connected to the driving wheel 62 to drive the driving wheel 62 to rotate. The transmission element 64 includes but is not limited to a conveying belt. In this way, when the third driving mechanism 61 is working, it drives the driving wheel 62 and the driven wheel 63 to rotate, thereby driving the transmission element 64 to move, and then can drive the material 30 to perform a loading action or a unloading action.

[0046] See also Figure 1 , Figure 3 and Figure 4 In one embodiment, the flipping mechanism further includes a lifting mechanism 70. The lifting mechanism 70 is used to drive the second bracket 50 to lift. In this way, regardless of the loading or unloading step of the material 30, since the lifting mechanism 70 can drive the second bracket 50 to lift, it drives the first bracket 20 to adjust the height position up and down to compensate for the height difference caused by the flipping of the first bracket 20, so that the input part on the first bracket 20 can be consistent in height with the output end of the loading mechanism 93, so that the loading mechanism 93 can smoothly and quickly output the material 30 to the first bracket 20, and the output part on the first bracket 20 can be consistent in height with the input end of the unloading mechanism, so that the material 30 can be smoothly and quickly output to the unloading mechanism.

[0047] See also Figure 1 , Figure 3 and Figure 4Specifically, the flip mechanism further includes a third bracket 80. The lifting mechanism 70 is mounted on the third bracket 80. The second bracket 50 is slidably disposed on the third bracket 80. In this way, when the lifting mechanism 70 drives the second bracket 50 to move up and down to adjust the position, since the second bracket 50 can slide up and down along the third bracket 80, the operation of the second bracket 50 is stable and reliable.

[0048] In some embodiments, the lifting mechanism 70 includes but is not limited to a screw, a cylinder, a hydraulic cylinder, a cam mechanism, a motor drive wheel mechanism, a gear drive mechanism, etc., and can be flexibly adjusted and set according to actual needs and is not limited here.

[0049] In one embodiment, the flipping mechanism further includes a position sensor and a controller. The position sensor is arranged on the second bracket 50 and is used to sense the rotation position of the first bracket 20, and the controller is electrically connected to the position sensor and the second driving mechanism 40 respectively. In this way, the position sensor is arranged on the second bracket 50 and can sense the rotation position of the first bracket 20, and send the rotation position of the first bracket 20 to the controller, thereby playing the role of calibrating the position. Under the control of the controller, the flipping angle of the first bracket 20 can be accurately controlled, thereby avoiding the situation of flipping too much or too little, resulting in the inability to dock with the loading and unloading mechanism.

[0050] In a specific embodiment, the position sensors include but are not limited to two, and the two position sensors are respectively set corresponding to the loading position and the unloading position. In this way, when the first bracket 20 rotates to the loading position or the unloading position, it can be sensed by the corresponding position sensor, and the position sensor sends a sensing signal to the controller. Under the control of the controller, the first bracket 20 will be positioned in time after being flipped into place, avoiding the situation of flipping too much or too little, resulting in failure to dock with the loading and unloading mechanism.

[0051] Among them, the controller includes but is not limited to a PLC control device, which can control the action of the second drive mechanism 40 accordingly, and can set different control parameters according to the materials 30 of different thicknesses and different material types, and can be connected to the MES system to implement monitoring work data.

[0052] In some embodiments, the second driving mechanism 40 includes a servo motor. The servo motor can accurately control the rotation speed and angle of the first bracket 20. The second driving mechanism 40 includes an encoder, which can obtain rotation angle information and transmit the rotation angle information to the controller, and work under the control of the controller, so as to accurately control the flip angle position of the first bracket 20.

[0053] See also Figure 1 and Figure 2In one embodiment, a solar cell production line includes the flipping mechanism of any one of the above embodiments.

[0054] The above-mentioned solar cell production line is provided with a clamping assembly 10. Before the material 30 is turned over, the material 30 is first clamped by the clamping assembly 10, and then the second driving mechanism 40 is driven to drive the first bracket 20 to rotate, so that the material 30 can be turned over to a preset angle. In this embodiment, since the first driving mechanism 11 includes a servo electric cylinder 111, the servo electric cylinder 111 acts on each swing assembly 12 in a linear driving manner. After the swing assembly 12 is driven by the servo electric cylinder 111, the linear driving action of the servo electric cylinder 111 can be converted into rotation. In this embodiment, the servo electric cylinder 111 is a high-precision instrument that can more accurately control the speed and torque, so that the clamping degree of the two clamping rods 121 on the material 30 is flexible and controllable, and the material 30 can be prevented from being too loose or too tight. The clamping force can be adjusted in time and accurately according to the properties of the material 30 and / or the thickness of the material 30, so that not only the materials 30 of different thicknesses can be stably clamped, but also the materials 30 can be prevented from being damaged.

[0055] See also Figures 1 to 5 , Figure 5 A partial structural diagram of a solar cell production line of an embodiment of the present application is shown. The solar cell production line also includes a paper picking gripper 91, a feeding gripper 92 and a feeding mechanism 93 located upstream of the turning mechanism, and a feeding mechanism located downstream of the turning mechanism. Among them, the material 30 is specifically, for example, photovoltaic glass, and the paper picking gripper 91 can, for example, take away the kraft paper on the material 30, thereby eliminating the need for manual operation and improving the degree of automation. Then, the feeding gripper 92 grabs the material 30 and sends it to the feeding mechanism 93. The feeding mechanism 93 is specifically, for example, provided with a correction component, which can correct the material 30 so that the material 30 is located in the middle of the conveyor line. After the material 30 is corrected, the material 30 is conveyed to the first bracket 20 by the feeding mechanism 93.

[0056] In a specific embodiment, the workflow of the solar cell production line includes the following steps:

[0057] A stacked material 30 is placed on the feeding gripper 92, the kraft paper on the material 30 is taken away by the paper taking gripper 91, and then the feeding gripper 92 grabs the material 30 into the feeding mechanism 93;

[0058] The alignment component of the feeding mechanism 93 performs alignment processing on the material 30 so that the material 30 is centered and arranged neatly, so that it can enter the first bracket 20 in the center;

[0059] Driven by the conveying component 60, after the material 30 enters the preset position of the first bracket 20, the material 30 is clamped by the clamping component 10; specifically, before the material 30 is conveyed to the first bracket 20, the height position of the second bracket 50 can also be adjusted by the lifting mechanism 70, so that the input part of the first bracket 20 is aligned with the output part of the feeding mechanism 93, which is convenient for feeding.

[0060] The second driving mechanism 40 drives the first bracket 20 to flip, for example, 180 degrees, so as to realize the flipping of the material 30. After the first bracket 20 drives the material 30 to flip, the material unloading step is entered;

[0061] The conveying assembly 60 drives the material 30 to move, so that the material 30 enters the unloading mechanism. Specifically, before the material 30 is output from the first bracket 20, the height position of the second bracket 50 can be adjusted by the lifting mechanism 70, so that the output part of the first bracket 20 is aligned with the input part of the unloading mechanism, which is convenient for unloading.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0065] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0066] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
