Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, specifically to a clamp-type photovoltaic silicon rod stable gripping unit mechanism. Background Technology

[0002] Photovoltaic silicon rods are the main photovoltaic materials. When processing photovoltaic silicon rods, corresponding gripping units are usually used to facilitate the gripping and transfer of photovoltaic silicon rods. The gripping units stably clamp the photovoltaic silicon rods.

[0003] For example, Chinese Patent No. CN109397568A, with Publication No. 2019-03-01 and titled "A Single Crystal Silicon Rod Square Root Clamping Device," includes a single crystal silicon rod clamping mechanism. The single crystal silicon rod clamping mechanism includes a front clamping mechanism, a tail clamping mechanism, and a single crystal silicon rod clamping mechanism drive mechanism. The tail clamping mechanism and the front clamping mechanism are arranged opposite each other for clamping and rotating the single crystal silicon rod. The single crystal silicon rod clamping mechanism drive mechanism is located between the tail clamping mechanism and the front clamping mechanism for driving the tail clamping mechanism and the front clamping mechanism to move closer or further apart. Both the tail clamping mechanism and the front clamping mechanism are equipped with sensors for scanning the shape features of the single crystal silicon rod.

[0004] The existing technology has the following technical problems: When clamping photovoltaic silicon rods, the existing clamping device can only limit the position of the silicon rod by clamping. During the clamping and transfer process, the photovoltaic silicon rod is prone to falling due to factors such as equipment vibration, which reduces the stability of the photovoltaic silicon rod gripping. At the same time, it is not convenient to clean the dust and impurities attached to the gripping area when gripping the photovoltaic silicon rod. Therefore, when there is dust and impurities in the gripping area, the clamping claws squeeze the dust or impurities, causing wear on the surface of the silicon rod.

[0005] Therefore, we propose a clamp-type photovoltaic silicon rod stable gripping unit mechanism to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a clamp-type photovoltaic silicon rod stable gripping unit mechanism to solve the problems mentioned in the background art. Currently available clamping devices on the market can only limit the position of photovoltaic silicon rods by clamping them. During the clamping and transfer process, the photovoltaic silicon rods are prone to falling due to factors such as equipment vibration, which reduces the stability of the photovoltaic silicon rod gripping. At the same time, it is not convenient to clean the dust and impurities attached to the gripping area when gripping the photovoltaic silicon rod. As a result, when there is dust and impurities in the gripping area, the clamping claws squeeze the dust or impurities, causing wear on the surface of the silicon rod.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a clamp-type photovoltaic silicon rod stable gripping unit mechanism, including a base, a protective cover is provided at the upper end of the base, and the protective cover is connected to an external robotic arm, a servo motor is fixedly connected to the side of the protective cover, and a transmission gear is fixedly connected to the output end of the servo motor, a movable rack is meshed with the side of the transmission gear, and the movable rack is fixed to the side of the lifting column. Also includes: Two cylinders are fixedly installed on the upper end of the base, and a movable arm is fixedly connected to the telescopic end of each cylinder. The end of the movable arm is mounted on the guide rail via a slider, and the guide rail is fixed to the upper side of the base. Two grippers are fixedly connected to one of the movable arms. A self-cleaning lifting component is installed on the gripper, and the self-cleaning lifting component is used to lift the silicon rod and perform air blowing self-cleaning on the clamping area.

[0008] Preferably, the movable arms are symmetrically arranged about the transverse central axis of the base, and the symmetrically distributed movable arms can move on the guide rail through a slider that is fixedly connected.

[0009] By adopting the above technical solution, the relative movement of the two movable arms on the guide rail enables the clamps on them to clamp and limit the silicon rod.

[0010] Preferably, the lifting self-cleaning component includes a first adjusting rod, an elastic pad, a receiving column, a moving rod, a first rubber bladder, an air supply pipe, an air hole, a linkage gear, a second adjusting rod, an auxiliary spring, a second rubber bladder, a flow pipe, a diversion groove, an air outlet pipe, a guide pipe, a column, a vertical rod, an internal spring, and a buffer pad; The first adjusting rod is installed through the gripper, and an elastic pad is fixedly connected to the end of the first adjusting rod that contacts the silicon rod. A receiving column is provided above the elastic pad, and the receiving column is fixed to the first adjusting rod. A moving rod is installed through the receiving column, and a first rubber bladder is fixedly connected to the end of the moving rod that extends out of the receiving column. The end of the first adjusting rod near the elastic pad is set to a hollow structure, and the hollow end of the first adjusting rod is connected to the receiving column through an air supply pipe. Air holes are opened on the sides of both the elastic pad and the hollow end of the first adjusting rod. A linkage gear is provided below the end of the first adjusting rod away from the elastic pad, and a second adjusting rod is installed below the linkage gear. The second adjusting rod and the first adjusting rod are connected to each other by an auxiliary spring and a gripper. A second rubber bladder is fixedly connected to the lower end of the second adjusting rod. The second rubber bladder is connected to each other by a flow pipe and a diversion groove. The diversion groove is opened inside the second adjusting rod. An air outlet pipe is connected to the upper end of the diversion groove. A guide pipe is connected to the side of the flow pipe. The end of the guide pipe away from the flow pipe is connected to a column. The column is fixed to the end of the second adjusting rod, and a vertical rod is installed through the column. The vertical rod is connected to the inside of the column by an internal spring, and a buffer pad is fixedly connected to the upper end of the vertical rod.

[0011] By adopting the above technical solution, the rubber pad at the end of the first adjusting rod can provide a clamping and buffering effect on the silicon rod.

[0012] Preferably, the lower end of the first adjusting rod near the linkage gear and the upper end of the second adjusting rod near the linkage gear are both provided with a serrated structure, and the serrated ends of the first adjusting rod and the second adjusting rod are meshed with the linkage gear, and the first adjusting rod and the second adjusting rod can slide on the gripper.

[0013] By adopting the above technical solution, when the first adjusting rod moves, the linkage gear can drive the second adjusting rod to move synchronously.

[0014] Preferably, one end of the moving rod that extends into the receiving column forms a seamless sliding connection structure with the receiving column through a circumferentially fixed sealing ring, and the airflow inside the receiving column can enter the hollow end of the first adjusting rod through the air supply pipe, and the air holes on the side of the hollow end of the first adjusting rod and the air holes on the elastic pad are aligned with each other.

[0015] By adopting the above technical solution, the sealing performance of the moving rod can be improved when it moves inside the receiving column by using the sealing ring at the end of the moving rod.

[0016] Preferably, the second rubber bladder extends beyond the lower end of the second adjusting rod, and both the second rubber bladder and the first rubber bladder have a hollow interior structure.

[0017] By adopting the above technical solution, when the two movable arms and their grippers move relative to each other, the second rubber bladder on the second adjusting rod can be made to contact and squeeze first.

[0018] Preferably, the airflow inside the second rubber bladder can enter the interior of the diversion groove through the flow pipe, and multiple air outlet pipes are evenly distributed at the upper end of the diversion groove.

[0019] By adopting the above technical solution, when the second rubber bladder is squeezed, the airflow inside can enter the interior of the diversion groove through the flow pipe, and be ejected outward through the air outlet pipe at the upper end of the diversion groove.

[0020] Preferably, the end of the vertical rod located inside the column forms a seamless sliding connection structure with the column through a circumferentially fixed sealing ring, and the vertical rod and the second adjusting rod are vertically distributed.

[0021] By adopting the above technical solution, the vertical rod can be moved along the top of the second adjusting rod to contact the bottom of the silicon rod, thereby lifting the clamped silicon rod.

[0022] Preferably, the buffer pad at the upper end of the vertical rod is made of elastic rubber.

[0023] By adopting the above technical solution, the buffer pad can come into contact with the silicon rod after the vertical rod is moved upward. The buffer pad on the silicon rod plays a buffering role, and excessive contact force will damage the silicon rod.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the clamp-type photovoltaic silicon rod stable gripping unit mechanism can clamp and limit the photovoltaic silicon rod while supporting and bearing it, thereby improving the stability of the photovoltaic silicon rod during gripping. At the same time, it can blow air to clean the gripping area of ​​the photovoltaic silicon rod during gripping, thus avoiding wear on the surface of the silicon rod. 1. Equipped with grippers, the two movable arms can move relative to each other on the guide rail by extending and retracting two cylinders. The relative movement of the two movable arms can be used to clamp and limit the photovoltaic silicon rod through the grippers on them. 2. It is equipped with a first adjusting rod and a second adjusting rod. When the first adjusting rod contacts the silicon rod, it can slide on the gripper. At the same time, after the first adjusting rod moves, it can use the meshing linkage gear to make the second adjusting rod move towards the inside of the gripper. After the gripper moves relative to each other, the second rubber bladders on the two second adjusting rods can be squeezed. At this time, part of the airflow in the second rubber bladder can enter the interior of the column through the guide tube. As the airflow inside the column increases, it can push the vertical rod to move upward and make the buffer pad on it contact the silicon rod, thereby lifting the silicon rod. 3. Equipped with air vents, when the grippers on the two movable arms move relative to each other, the first rubber bladder is compressed. This compression pushes the moving rod inside the receiving column, and the airflow inside the receiving column enters the hollow end of the first adjusting rod through the air supply pipe. The airflow then sprays out towards the silicon rod surface through the air vents on the first adjusting rod and the elastic pad. Simultaneously, another portion of the airflow inside the second rubber bladder, after compression, enters the distribution groove through the flow pipe. The airflow in the distribution groove sprays out towards the silicon rod through the air outlet pipe. This utilizes the airflow ejected from the silicon rod to clean dust and impurities in the clamping area, preventing surface wear on the silicon rod due to the compression of dust and impurities after clamping.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1-9 Existing clamping devices can only limit the position of photovoltaic silicon rods by clamping them. During the clamping and transfer process, the photovoltaic silicon rods are prone to falling due to factors such as equipment vibration, which reduces the stability of the photovoltaic silicon rod gripping. This embodiment discloses the following technical content. A clamp-type photovoltaic silicon rod stable gripping unit mechanism includes a base 1, a protective cover 2 at the upper end of the base 1, and the protective cover 2 is connected to an external robotic arm. A servo motor 3 is fixedly connected to the side of the protective cover 2, and a transmission gear 4 is fixedly connected to the output end of the servo motor 3. A movable rack 5 is meshed with the side of the transmission gear 4, and the movable rack 5 is fixed to the side of the lifting column 6. Two cylinders 7 are fixedly installed at the upper end of the base 1, and a movable arm 8 is fixedly connected to the extension end of each cylinder 7. The end of the movable arm 8 is mounted on a guide rail 9 via a slider, and the guide rail 9 is fixed to the upper side of the base 1. Two grippers 10 are fixedly connected to each movable arm 8, and a lifting self-cleaning component 11 is installed on the gripper 10. The lifting self-cleaning component 11 is used to lift the silicon rod and to blow air to clean the gripping area. The movable arms 8 are symmetrically arranged about the transverse central axis of the base 1, and the symmetrically distributed movable arms 8 can move on the guide rail 9 via the fixedly connected slider.The self-cleaning lifting component 11 includes a first adjusting rod 111, an elastic pad 112, a receiving column 113, a moving rod 114, a first rubber bladder 115, an air supply pipe 116, an air hole 117, a linkage gear 118, a second adjusting rod 119, an auxiliary spring 1110, a second rubber bladder 1111, a flow pipe 1112, a diversion groove 1113, an air outlet pipe 1114, a guide pipe 1115, a column 1116, a vertical rod 1117, an internal spring 1118, and a buffer pad 1119; the first adjusting rod 111 is mounted through the gripper 10, and the first An elastic pad 112 is fixedly connected to the end of the adjusting rod 111 that contacts the silicon rod. A receiving post 113 is provided above the elastic pad 112 and is fixed to the first adjusting rod 111. A moving rod 114 is installed through the receiving post 113, and a first rubber bladder 115 is fixedly connected to the end of the moving rod 114 that extends out of the receiving post 113. The end of the first adjusting rod 111 near the elastic pad 112 is hollow, and the hollow end of the first adjusting rod 111 is connected to the receiving post 113 through a gas supply pipe 116. The elastic pad 112... Both the hollow end of the first adjusting rod 111 and the first adjusting rod 111 have air holes 117 on their sides. A linkage gear 118 is provided below the end of the first adjusting rod 111 away from the elastic pad 112, and a second adjusting rod 119 is installed below the linkage gear 118. The second adjusting rod 119 and the first adjusting rod 111 are connected to each other by an auxiliary spring 1110 and a gripper 10. A second rubber bladder 1111 is fixedly connected to the lower end of the second adjusting rod 119. The second rubber bladder 1111 is connected to each other by a flow pipe 1112 and a diversion groove 1113. An air outlet pipe 1114 is connected to the upper end of the flow channel 1113 inside the second adjusting rod 119. A guide pipe 1115 is connected to the side of the flow pipe 1112, and the end of the guide pipe 1115 away from the flow pipe 1112 is connected to the column 1116. The column 1116 is fixed to the end of the second adjusting rod 119, and a vertical rod 1117 is installed through the column 1116. The vertical rod 1117 is connected to the inside of the column 1116 through a built-in spring 1118, and a buffer pad 1119 is fixedly connected to the upper end of the vertical rod 1117. The lower end of the first adjusting rod 111 near the linkage gear 118 and the upper end of the second adjusting rod 119 near the linkage gear 118 are both provided with a serrated structure, and the serrated ends of the first adjusting rod 111 and the second adjusting rod 119 are meshed with the linkage gear 118. The first adjusting rod 111 and the second adjusting rod 119 can slide on the gripper 10. One end of the moving rod 114 extends into the receiving column 113 and forms a seamless sliding connection structure with the receiving column 113 through a circumferentially fixed sealing ring. The airflow inside the receiving column 113 can enter the hollow end of the first adjusting rod 111 through the air supply pipe 116. The air hole 117 on the side of the hollow end of the first adjusting rod 111 and the air hole 117 on the elastic pad 112 are aligned with each other.The second rubber bladder 1111 extends from the lower end of the second adjusting rod 119, and both the second rubber bladder 1111 and the first rubber bladder 115 have hollow interiors. Airflow inside the second rubber bladder 1111 can enter the interior of the diversion groove 1113 through the flow pipe 1112, and multiple air outlet pipes 1114 are evenly distributed at the upper end of the diversion groove 1113. One end of the vertical rod 1117 located inside the column 1116 forms a seamless sliding connection with the column 1116 via a circumferentially fixed sealing ring, and the vertical rod 1117 and the second adjusting rod 119 are vertically distributed. The buffer pad 1119 at the upper end of the vertical rod 1117 is made of elastic rubber.

[0029] When it is necessary to grasp the silicon rod, the entire device is moved by the robotic arm. Then, the servo motor 3 is turned on, which causes the transmission gear 4 to rotate. The rotation of the transmission gear 4 causes the meshing movable rack 5 to move the base 1 up and down. This causes the gripper 10 on the movable arm 8 to move to the side of the silicon rod. Then, the cylinder 7 is turned on, causing the two movable arms 8 to move relative to each other on the guide rail 9 via the slider on them. The relative movement of the two movable arms 8 allows the gripper 10 to grasp the silicon rod. After the two movable arms 8 drive the gripper 10 to move relative to each other, the first rubber bladder 115 and the second rubber bladder 1111 on the first adjusting rod 111 and the second adjusting rod 119 first come into contact and squeeze each other. After being compressed, the first rubber bladder 115 first pushes the moving rod 114 to move inside the receiving column 113. When the moving rod 114 moves to its limit distance, the first rubber bladder 115 continues to be squeezed and extends vertically to contact the silicon rod, while the second rubber bladder 111... 1. After being compressed, a portion of the internal airflow enters the interior of the column 1116 through the guide pipe 1115. As the airflow inside the column 1116 increases, it can push the vertical rod 1117 upward. Subsequently, the two movable arms 8 drive the gripper 10 to continue moving relative to each other, enabling the first adjusting rod 111 to contact the silicon rod. After contacting the silicon rod, the first adjusting rod 111 can move on the gripper 10. After the first adjusting rod 111 moves, it can cause the second adjusting rod 119 to move through the meshing linkage gear 118. Moving towards the inner side of the base 1, the movement of the second adjusting rod 119 allows the extended vertical rod 1117 to contact the bottom of the silicon rod. The vertical extension of the first rubber bladder 115 and its contact with the silicon rod, along with the contact between the buffer pad 1119 and the bottom of the silicon rod, allow for vertical clamping of the silicon rod. This clamping of the silicon rod by the first adjusting rod 111 and the first rubber bladder 115 and buffer pad 1119 improves the stability of the silicon rod during gripping and transfer.

[0030] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. When gripping photovoltaic silicon rods, it is inconvenient to clean dust and impurities adhering to the gripping area. Therefore, when dust and impurities are present in the gripping area, the grippers 10 squeeze the dust or impurities, causing wear on the surface of the silicon rod. To further solve this technical problem, this example discloses the following technical content: Figures 1-9 As shown; The self-cleaning lifting component 11 includes a first adjusting rod 111, an elastic pad 112, a receiving column 113, a moving rod 114, a first rubber bladder 115, an air supply pipe 116, an air hole 117, a linkage gear 118, a second adjusting rod 119, an auxiliary spring 1110, a second rubber bladder 1111, a flow pipe 1112, a diversion groove 1113, an air outlet pipe 1114, a guide pipe 1115, a column 1116, a vertical rod 1117, an internal spring 1118, and a buffer pad 1119; the first adjusting rod 111 is mounted through the gripper 10, and the first An elastic pad 112 is fixedly connected to the end of the adjusting rod 111 that contacts the silicon rod. A receiving post 113 is provided above the elastic pad 112 and is fixed to the first adjusting rod 111. A moving rod 114 is installed through the receiving post 113, and a first rubber bladder 115 is fixedly connected to the end of the moving rod 114 that extends out of the receiving post 113. The end of the first adjusting rod 111 near the elastic pad 112 is hollow, and the hollow end of the first adjusting rod 111 is connected to the receiving post 113 through a gas supply pipe 116. The elastic pad 112... Both the hollow end of the first adjusting rod 111 and the first adjusting rod 111 have air holes 117 on their sides. A linkage gear 118 is provided below the end of the first adjusting rod 111 away from the elastic pad 112, and a second adjusting rod 119 is installed below the linkage gear 118. The second adjusting rod 119 and the first adjusting rod 111 are connected to each other by an auxiliary spring 1110 and a gripper 10. A second rubber bladder 1111 is fixedly connected to the lower end of the second adjusting rod 119. The second rubber bladder 1111 is connected to each other by a flow pipe 1112 and a diversion groove 1113. An air outlet pipe 1114 is connected to the upper end of the diversion groove 1113 inside the second adjusting rod 119. A guide pipe 1115 is connected to the side of the flow pipe 1112, and the end of the guide pipe 1115 away from the flow pipe 1112 is connected to the column 1116. The column 1116 is fixed to the end of the second adjusting rod 119, and a vertical rod 1117 is installed through the column 1116. The vertical rod 1117 is connected to the inside of the column 1116 through a built-in spring 1118, and a buffer pad 1119 is fixedly connected to the upper end of the vertical rod 1117.

[0031] When the first rubber bladder 115 is squeezed, it can first push the moving rod 114 to move inside the receiving column 113. The movement of the moving rod 114 can allow the airflow inside the receiving column 113 to enter the hollow end of the first adjusting rod 111 through the air supply pipe 116. After the airflow enters the hollow end of the first adjusting rod 111, the airflow can be ejected outward through the air hole 117. The airflow ejected through the air hole 117 cleans the clamping area of ​​the silicon rod. After the second rubber bladder 1111 is squeezed together, another part of the airflow inside can enter the interior of the diversion groove 1113 through the flow pipe 1112. The airflow in the diversion groove 1113 is ejected towards the surface of the silicon rod through the air outlet pipe 1114, thereby further blowing and cleaning the clamping area of ​​the silicon rod. This avoids the first adjusting rod 111, the first rubber bladder 115 and the buffer pad 1119 from contacting the surface of the silicon rod, which would cause the dust and impurities to be squeezed and cause wear on the surface of the silicon rod.
