The transmission belt can be a high-friction belt or an adsorption belt; in the direction perpendicular to the transmission direction, the accuracy problem in this direction is solved by adding centering clamping. This mode can improve a certain positioning accuracy, but it increases gas consumption, and also increases the debugging workload of employees and increases the fragmentation rate of solar cells. After the current centering clamping guide wheel is opened, it is on the same level as the transmission belt and the guide wheel is higher than the belt, which will cause the risk of solar cells being broken during loading and unloading.

[0023] The present application provides a material transmission positioning device 100, see Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of a material transmission and positioning device provided in the present application.

[0024] The material transmission and positioning device 100 includes a transmission mechanism 10 and a centering mechanism 20. The transmission mechanism 10 is used to transmit materials along a first direction A. The centering mechanism 20 includes a driving sub-mechanism 22 and two clamping members 24 arranged at intervals along a second direction B. The driving sub-mechanism 22 is arranged below the transmission mechanism 10 and is connected to the two clamping members 24. The second direction B is perpendicular to the first direction A. The centering mechanism 20 includes a centering clamping state and an opening state. When the centering mechanism 20 is in the centering clamping state, the driving sub-mechanism 22 drives the two clamping members 24 to move from below the transmission surface 101 of the transmission mechanism 10 to above the transmission surface 101 and clamp toward each other. When the centering mechanism 20 is in the opening state, the driving sub-mechanism 22 drives the two clamping members 24 to move away from each other and move from above the transmission surface 101 to below the transmission surface 101. The first direction A and the second direction B are two directions perpendicular to each other in the transmission surface 101.

[0025] The transmission mechanism 10 can be used to transmit materials such as solar cells, liquid crystal panels or wafers, and the suction cup device can load the materials onto the transmission mechanism 10 or remove the materials from the transmission mechanism 10. The device for taking and placing materials is usually a rotating arm suction cup device, the suction cup adsorption surface adsorbs the materials downward, and then the rotating arm rotates to load the materials onto the transmission mechanism 10 or remove them from the transmission mechanism 10. The clamping parts of the centering mechanism of the prior art are always located in the same horizontal plane, and only clamping or opening will cause the rotating arm suction cup to hit the clamping parts during the material taking and placing process, resulting in fragments.

[0026] In the present application, the driving sub-mechanism 22 is arranged below the transmission mechanism 10, and the two clamping members 24 are arranged at opposite sides of the transmission mechanism 10 at relative intervals. When there is no need to center and clamp the correction material, the two clamping members 24 are below the transmission surface 101 of the transmission mechanism 10, so that the suction cup device and the like can avoid interference from the centering mechanism 20 when taking and placing materials. For example, when loading materials, the adsorption surface of the suction cup device can be very close to the top of the transmission mechanism 10, and the interference of the centering mechanism 20 on the material is completely eliminated in the process of taking and placing materials, and the suction cup device can take and place materials more gently, avoiding the risk of fragmentation.

[0027] Specifically, when the material carried on the conveying mechanism 10 needs to be centered, the driving sub-mechanism 22 can drive the two clamping members 24 to move toward each other and move from below the conveying surface 101 of the conveying mechanism 10 to above the conveying surface 101. The two clamping members 24 that move to the conveying surface 101 move toward each other along the second direction B to clamp and correct the material so as to center the material.

[0028] After completing the centering positioning, the driving sub-mechanism 22 drives the two clamping members 24 to move in opposite directions along the second direction B and from above the transmission surface 101 of the transmission mechanism 10 to below the transmission surface 101, so that the space above the transmission surface 101 of the transmission mechanism 10 can be fully used by the device for taking and placing materials, thereby avoiding interference with the process of taking and placing materials.

[0029] The movement of the clamping member 24 above the transmission surface 101 of the transmission mechanism 10 means that at least part of the clamping member 24 exceeds the transmission surface 101 of the transmission mechanism 10; the movement of the clamping member 24 below the transmission surface 101 of the transmission mechanism 10 means that the clamping member 24 does not exceed the transmission surface 101 of the transmission mechanism 10.

[0030] In this embodiment, the transmission surface 101 of the transmission mechanism 10 is used to carry and transmit materials, and when the clamping member 24 moves above the transmission surface 101, the materials can be conveniently centered and positioned.

[0031] Optionally, the conveying mechanism 10 may include a plurality of rollers arranged along the first direction A, and the plurality of rollers may jointly define a conveying surface 101 for carrying materials.

[0032] See also Figure 2 , Figure 2 yes Figure 1 The schematic diagram of the structure of the transmission mechanism in the material transmission and positioning device is shown.

[0033] In this embodiment, the transmission mechanism 10 includes a second motor 12 and a belt mechanism 14 . The second motor 12 is transmission-connected to the belt mechanism 14 . The transmission surface 101 of the transmission mechanism 10 is the upper surface of the belt of the belt mechanism 14 .

[0034] Among them, the belt mechanism 14 includes a driving shaft 141, a driving wheel 142, a driven wheel 143 and a belt 144. The driving wheel 142 is installed on the driving shaft 141, and the driven wheel 143 and the driving wheel 142 are arranged at intervals along the first direction A. The belt 144 is connected between the driving wheel 142 and the driven wheel 143. The second motor 12 is connected to the driving shaft 141 through a synchronous belt, and then drives the driving wheel 142 to drive the belt 144 to move, so that materials can be transported along the first direction A. The belt 144 is used to carry materials. The belt 144 can be a high-friction belt or an adsorption belt, so that the material is not easy to slip thereon.

[0035] There can be at least two groups of driving wheels 142 and driven wheels 143, and each group of driving wheels 142 and driven wheels 143 is connected to a belt 144, so that materials can be carried together by multiple belts 144 arranged along the second direction B; or, one belt 144 is connected to multiple groups of driving wheels 142 and driven wheels 143; or, one belt 144 can also be connected to all driving wheels 142 and driven wheels 143.

[0036] By setting up a belt sub-mechanism 14, and the upper surface of the belt of the belt sub-mechanism 14 is the transmission surface 101, wherein the belt 144 can be a high-friction belt, or the belt is provided with adsorption holes, and an adsorption chamber is provided thereunder to adsorb the material, so that the material can resist vibration or shaking, and can maintain the stability of the material during transportation, reduce the displacement error caused by the transportation of the transmission mechanism 10, and improve the accuracy of conveying materials.

[0037] In this embodiment, the belt sub-mechanism 14 includes two belts 144 spaced apart along the second direction B. The two belts 144 are used to define a material carrying area. The two clamping members 24 are disposed on opposite sides of the two belts 144 .

[0038] The transmission mechanism 10 also includes a sensor 16 arranged between the two belts 144. The sensor 16 is used to detect the material transmitted on the belt 144. There are two logics for the material to move on the belt 144: first, the material moves on the belt 144 at a high speed until the previous sensor 16 senses the material, the belt sub-mechanism 14 stops working, and then the centering mechanism 20 changes from an open state to a clamping state and then to an open state, and then the material moves on the belt 144 at a low speed until the next sensor 16 senses the material, the belt sub-mechanism 14 stops working, thereby completing the positioning of the material on the belt sub-mechanism 14; second, the material moves on the belt 144 at a high speed until the previous sensor 16 senses the material, the belt sub-mechanism 14 stops working, and then the material moves on the belt 144 at a low speed until the next sensor 16 senses the material, the belt sub-mechanism 14 stops working again, and then the centering mechanism 20 changes from an open state to a clamping state and then to an open state, thereby completing the positioning of the material on the belt module.

[0039] The sensor 16 can be an infrared sensor or a distance sensor, etc., which is arranged on the installation panel 145 and located between the two belts 144, so that after the material is transmitted to the detection position of the sensor 16, the sensor 16 can be triggered to send a signal to the centering mechanism 20, so that the centering mechanism 20 starts to work to center, clamp and position the material transported on the belt 144 to correct the position accuracy of the material.

[0040] Optionally, the number of the sensor 16 may be one, so that after it detects the material, it can send a signal to perform centering correction on the material.

[0041] Optionally, the number of sensors 16 is at least two and they are arranged along the first direction A, for example, the number of sensors 16 is two or three.

[0042] In this embodiment, there are two sensors 16 and they are arranged along the first direction A, and the distance between the two sensors 16 is 8-15mm. The distance between the two sensors 16 can specifically be 8mm, 10mm, 12mm or 15mm, etc.; both sensors 16 are used to detect the position of the material, and the two sensors 16 can be divided into two sections along the first direction A. The transmission speed of the first section of the material transported to the previous sensor 16 is greater than the transmission speed of the second section of the material between the previous sensor 16 and the next sensor 16, that is, the first section is high-speed transmission, and the second section is low-speed transmission. The distance of the first section is greater than the distance of the second section, which can greatly improve the transmission efficiency of the material.

[0043] Optionally, after the material is transmitted to the previous sensor 16 at high speed and detected by the previous sensor 16, the material transmission is stopped, and the centering mechanism 20 enters a centering clamping state to perform centering correction on the material. The material is then transmitted to the next sensor 16 at low speed. The low-speed transmission of the corrected material can reduce the risk of the material slipping on the belt 144, thereby improving the transportation accuracy. The material stops after being transported to the next sensor 16 and can be taken away by the adsorption device. The next sensor 16 can further locate the unloading position of the material.

[0044] Optionally, the material is transmitted to the previous sensor 16 at high speed. After the previous sensor 16 detects the material, the belt 144 reduces the transmission speed and carries the material through the previous sensor 16, and then transmits the material to the next sensor 16 at low speed. When the next sensor 16 detects the material, the material transmission is stopped, and the centering mechanism 20 enters the centering clamping state to perform centering correction on the material. The material can be unloaded after the centering correction is completed, thereby reducing the speed from high speed to low speed during material transportation, which can avoid material sliding caused by direct parking during high-speed transmission. Parking during low-speed transmission can better control the position accuracy of the material, and the material is corrected after parking and is no longer transmitted, which can relatively improve the transportation efficiency and transportation accuracy.

[0045] Combined with reference Figure 1 and Figure 3 ,in Figure 3 yes Figure 1 The schematic diagram of the structure of the centering mechanism in the material transmission and positioning device is shown.

[0046] In this embodiment, the driving sub-mechanism 22 includes two first guide rails 221, and the adjacent ends of the two first guide rails 221 are higher than the distant ends. The clamping members 24 are slidably connected to the corresponding first guide rails 221. The two clamping members 24 can move from below the transmission surface 101 to above the transmission surface 101 and clamp toward each other under the guidance of the corresponding first guide rails 221, and can also move away from each other and move from above the transmission surface 101 to below the transmission surface 101 under the guidance of the first guide rails 221.

[0047] The two first guide rails 221 are both obliquely installed on the support base 220 and arranged in an eight-shaped shape. The adjacent ends of the two first guide rails 221 are higher than the ends away from each other. Therefore, when the clamping members 24 are driven to clamp toward each other, the clamping members 24 gradually rise to above the transmission surface 101 to correct the material clamping. When the clamping members 24 are driven to move away from each other, the clamping members 24 gradually descend to below the transmission surface 101, thereby avoiding interference with the suction cup device and the like in taking and placing the material.

[0048] In this embodiment, the two first guide rails 221 are symmetrically arranged, so that the corresponding two clamping members 24 can have better movement consistency, so that the position accuracy correction of the material is more accurate.

[0049] Furthermore, the angle between the extension direction of the first guide rail 221 and the horizontal plane is greater than or equal to 15° and less than or equal to 25°. For example, the angle may be 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24° or 25°, etc.

[0050] This angle range can better take into account the lifting and centering clamping actions of the two clamping members 24, so that the clamping members 24 can reliably clamp the material after rising above the transmission surface 101 to center the material.

[0051] In this embodiment, the clamping member 24 includes a first adjustment plate 241, a second adjustment plate 242 and a plurality of guide wheels 243. The first adjustment plate 241 is slidably connected to the first guide rail 221, the second adjustment plate 242 is connected to the first adjustment plate 241, and the connection position between the second adjustment plate 242 and the first adjustment plate 241 is adjustable to adjust the height of the clamping member 24. The plurality of guide wheels 243 are connected to the second adjustment plate 242 and are used to center the clamped material.

[0052] The first adjustment plate 241 can be slidably connected to the first guide rail 221 through the slider mounting seat 244; multiple guide wheels 243 are rotatably connected to the top of the second adjustment plate 242, so that the multiple guide wheels 243 can roll in contact with the material, which can reduce contact damage to the material; the connection position between the second adjustment plate 242 and the first adjustment plate 241 is adjustable, and the height of the clamping member 24 can be adjusted, so as to adapt to more application scenarios, making the adjustment of the clamping member 24 more flexible and convenient to adapt to various working conditions.

[0053] Specifically, multiple rows of connection holes are provided on the first adjustment plate 241 or the second adjustment plate 242. By selecting a row of connection holes at different positions for connection, the height of the clamping member 24 can be adjusted, so that the multiple guide wheels 243 can accurately clamp the calibration material.

[0054] Furthermore, the driving sub-mechanism 22 further includes two first connecting rods 222 , one end of the first connecting rod 222 is rotatably connected to the corresponding clamping member 24 , and the first connecting rod 222 is used to drive the clamping member to slide along the first guide rail 221 .

[0055] Optionally, the two first connecting rods 222 can be driven by the same power source, or by different independent power sources; for example, the two first connecting rods 222 are driven by corresponding cylinders respectively, or the first connecting rods 222 are driven by the same cylinder or motor.

[0056] The first connecting rod 222 may be a straight rod or an L-shaped rod.

[0057] In this embodiment, the two clamping members 24 are driven by the same power source, and the driving sub-mechanism 22 also includes a second guide rail 223 and a slider 224. The second guide rail 223 is arranged along the vertical direction C, and the slider 224 is slidably connected to the second guide rail 223. The other end of the first connecting rod 222 is rotatably connected to the slider 224, and the slider 224 is driven to rise and fall along the second guide rail 223.

[0058] The slider 224 can be driven by the cylinder or the motor to rise and fall along the second guide rail 223, and then drive the clamping member 24 to move under the guidance of the first guide rail 221 through the first connecting rod 222. When the slider 224 rises, the clamping member 24 can be driven to rise through the first connecting rod 222 to move above the transmission surface 101, and the two clamping members 24 clamp each other; when the slider 224 descends, the clamping member 24 can be driven to descend through the first connecting rod 222 to move below the transmission surface 101, and the two clamping members 24 move away from each other.

[0059] In this embodiment, the driving sub-mechanism 22 also includes a first motor 225, a crank 226 and a second connecting rod 227. The crank 226 is connected to the output shaft of the first motor 225, and the second connecting rod 227 is rotatably connected between the crank 226 and the slider 224, so that the crank 226 and the second connecting rod 227 can convert the circular motion output by the first motor 225 into a linear reciprocating motion, so that the slider 224 reciprocates on the second guide rail 223.

[0060] By adopting a motor and a crank-connecting rod mechanism, it can better respond to control commands, the power output is more continuous, and the control accuracy is also higher.

[0061] Different from the prior art, the present application discloses a material transmission and positioning device. When the centering mechanism needs to perform centering correction on the material on the transmission mechanism, its clamping member moves from below the top surface of the transmission mechanism to above the top surface and performs clamping correction on the material. When the centering and clamping correction on the material is not required, its two clamping members are below the top surface of the transmission mechanism, so that the suction cup device and the like can avoid interference from the centering mechanism when taking and placing the material, thereby completely eliminating the interference of the centering mechanism on the material during loading and unloading, so that the material can avoid impact when taking and placing on the transmission mechanism, thereby eliminating the risk of fragmentation in this process.

[0062] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
