[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1As shown, the utility model discloses a clamping device, including two clamping units 10 arranged opposite to each other. When working, the two clamping units 10 arranged opposite to each other cooperate to clamp and position the two sides of the carrier, so as to facilitate other working devices to work. Specifically, each clamping unit 10 includes a support member 11, a clamping member 12 and a transmission member 13.

[0029] The support member 11 is used to install other components. Those skilled in the art can set the specific number, shape, size, material, etc. of the support member 11 according to actual needs. For example, in some embodiments, a plurality of support members 11 are provided; preferably, the support members 11 of the two clamping units 10 are combined to form an integrated structure. Preferably, the support member 11 is fixedly arranged.

[0030] The clamping member 12 is used to provide a force for the object to be clamped, so as to achieve its clamping and positioning, so as to facilitate the operation of other working devices. Preferably, in the embodiment, the object to be clamped is a carrier. Those skilled in the art can set the shape, size, material, etc. of the clamping member 12 according to actual needs, and will not be repeated here. There are multiple clamping members 12, for example, two, three, four, etc. Those skilled in the art can increase or decrease the number of clamping members 12 in a single clamping unit 10 according to the characteristics of the carrier, and can also change the relative position of the clamping member 12 according to the characteristics of the carrier. Each clamping member 12 can be rotatably connected to the support member 11; preferably, the clamping member 12 is rotatably connected to the support member 11 through a rotating shaft 123. Preferably, the axial direction of the rotating shaft 123 of each clamping member 12 is parallel; preferably, the axial direction of the rotating shaft 123 is perpendicular to the arrangement direction of the two clamping units 10.

[0031] The transmission component 13 is arranged on one side of the support member 11. Preferably, the transmission component 13 is arranged as a shaft-shaped structure; preferably, the axial direction of the transmission component 13 is parallel to the axial direction of the rotating shaft 123. The transmission component 13 is respectively connected to a plurality of clamping members 12; those skilled in the art can set the connection mode of the transmission component 13 and the clamping member 12 according to actual needs, for example, fixed connection, rotating connection, etc. The transmission component 13 is configured to be able to drive a plurality of clamping members 12 to rotate synchronously. Preferably, the transmission component 13 can rotate around the circumferential direction of the rotating shaft 123 of the clamping member 12, thereby driving each clamping member 12 to rotate, so as to achieve the avoidance or clamping action of the carrier; in some other embodiments, it can also be set as a composite motion of rotation and linear movement according to needs, etc., which will not be repeated. Those skilled in the art can set the specific driving mode of the transmission component 13 according to actual needs, for example, manual driving or setting a corresponding driving member to achieve driving, etc. By setting up this structure, each clamping unit 10 can drive multiple clamping members 12 through the transmission component 13. On the one hand, it eliminates the need for additional power sources, saves energy and improves space utilization; on the other hand, it effectively overcomes the problem of the prior art that multiple cylinder drives need to be set up, and the piston rod extension and extension are asynchronous and clamping fails due to asynchronous cylinder air supply or uneven air flow distribution. It can ensure synchronous clamping on the same side, which is stable and efficient.

[0032] Preferably, the support member 11 is an integrated structure, and a through hole 115 corresponding to the product on the carrier is opened in the middle of the support member 11. Figure 2 and Figure 3 As shown, in actual use, first, the transmission component 13 drives each clamping member 12 to rotate to a corresponding position to avoid the carrier. After the carrier is in place, the transmission component 13 drives each clamping member 12 to rotate to another corresponding position to cooperate with the support member 11 to clamp and position the carrier. After the clamping and positioning are completed, the corresponding operating device can realize the processing operation of the product on the carrier from the operating through hole 115. After the operation is completed, the transmission component 13 drives each clamping member 12 to rotate so that the current carrier is removed and the subsequent carrier is received.

[0033] The clamping device described in the utility model realizes the avoidance or clamping action of the carrier by providing a transmission component 13 for the clamping unit 10 to synchronously drive the multiple clamping members 12 to rotate. It can save additional power sources, save energy, reduce costs, and improve space utilization. In addition, it effectively overcomes the problem of the prior art that multiple cylinder drives need to be set, and the piston rod extension and extension are not synchronized due to the asynchronous cylinder air supply or uneven air flow distribution, and the clamping fails. It can ensure the synchronous, stable and efficient clamping on the same side.

[0034] Reference Figure 2As shown, in the clamping device described in the utility model, in some embodiments, the clamping unit 10 also includes a driving cylinder 14, so as to realize the driving of the transmission component through the driving cylinder 14. Specifically, the driving cylinder 14 can be rotatably arranged. Preferably, the clamping unit 10 includes a fixedly arranged cylinder support 141, and the driving cylinder 14 is rotatably connected to the cylinder support 141. Preferably, the rotating shaft axial direction of the cylinder support 141 and the driving cylinder 14 is axially parallel to the rotating shaft 123 of the clamping member 12. Preferably, the cylinder support 141 and the driving cylinder 14 are both arranged on the side of the support member 11 where the clamping member 12 is located. The piston rod of the driving cylinder 14 is connected to the transmission member 13. Those skilled in the art can set the specific connection mode of the piston rod and the transmission member 13 according to actual needs, for example, the piston rod is fixedly connected to the transmission member 13, and the transmission member 13 is rotatably connected to the clamping member 12, or the piston rod is rotatably connected to the transmission member 13, and the transmission member 13 is fixedly connected to the clamping member 12, etc. Preferably, the piston rod of the driving cylinder 14 is connected to the middle position of the transmission component 13 to facilitate uniform force application. In actual use, the piston rod of the driving cylinder 14 is extended and retracted, driving the transmission component 13 to move, thereby driving each clamping member 12 to rotate around its rotation axis 123 to achieve the avoidance or clamping action of the carrier. By setting up this structure, the fast response characteristics of the cylinder are fully utilized, and the operation can be achieved efficiently and stably. Detecting the position of the piston rod with the sensor in the prior art can prevent the occurrence of abnormal clamping problems such as vehicle tilting, misalignment, etc.

[0035] Reference Figure 4 and Figure 5 As shown, in the clamping device described in the present invention, in some embodiments, the clamping member 12 includes a clamping portion 121 and a connecting portion 122. The clamping portion 121 is used to clamp and position the carrier; the connecting portion 122 is connected to the transmission component 13 to achieve transmission. Those skilled in the art can set the specific relative position relationship between the two according to actual needs. Preferably, the clamping portion 121 and the connecting portion 122 are respectively arranged on both sides of the radial direction of the rotating shaft 123 of the clamping member 12, which is convenient for setting a driving member such as a driving cylinder 14 to avoid interference with the carrier.

[0036] Further, see Figure 5As shown, in some embodiments of the clamping device described in the utility model, a clamping pad 1211 is provided on the surface of the clamping portion 121 that contacts the object to be clamped. By providing the clamping pad 1211, problems such as wear can be effectively avoided. Those skilled in the art can set the material, shape and size of the clamping pad 1211 according to actual needs. Preferably, it is set to a rectangular structure or PEEK (polyetheretherketone). The clamping pad 1211 made of PEEK has high hardness and good wear resistance. When it repeatedly contacts the impact carrier or other components, such as the buffer 111, it will not cause damage to its surface, and it has good insulation to ensure that it can reduce the propagation of static electricity when it contacts the carrier.

[0037] In the clamping device of the present invention, in some embodiments, the clamping unit 10 further includes a buffer 111, the buffer 111 is connected to the support 11, and the buffer 111 is used to form a buffer when the clamping member 12 rotates. By providing the buffer 111, the damage to the carrier during the clamping process can be effectively reduced, and the service life of each component can be extended.

[0038] Further, see Figure 5 As shown, in some embodiments, a mounting hole 112 is provided on the surface of the support member 11 located on the side close to the clamping member 12. The buffer member 111 includes a buffer elastic member 1112 and a buffer abutting member 1113. The buffer elastic member 1112 is arranged in the mounting hole 112, and the two ends of the buffer elastic member 1112 are respectively connected to the buffer abutting member 1113 and the hole wall of the mounting hole 112. The buffer elastic member 1112 is used to provide elastic force to achieve buffering; the buffer abutting member 1113 is used to contact the clamping member 12. Preferably, the buffer elastic member 1112 is set as a spring, and the size of the buffer abutting member 1113 is smaller than the size of the mounting hole 112, so that the buffer abutting member 1113 can be retracted into the mounting hole 112 when subjected to force. Preferably, the buffer member 111 also includes a buffer mounting member 1111, and the buffer mounting member 1111 is set as a shaft-shaped structure, and the spring is sleeved on the outside of the buffer mounting member 1111, so as to facilitate structural stability and provide a certain guide. In the actual production process, the clamping member 12 will exert a certain force on the carrier under the action of the driving cylinder 14. To this end, a mounting hole 112 is set on the support member 11 and a buffer member 111 is installed, which can ensure that the clamping member 12 first contacts with the buffer member 111 during rotation to reduce the force, and then contacts with the carrier to reduce damage. At the same time, the buffer member 111 can also play a role of a soft limit to ensure that the clamping member 12 first contacts the buffer abutment member 1113, and then contacts the support member 11 that plays a hard limit role, thereby reducing the collision of forces and ensuring that the corresponding components reach the specified position.

[0039] Reference Figure 3As shown, in some embodiments of the clamping device of the present invention, a relief portion 113 is provided on the surface of the support member 11 located on the side close to the transmission member 13, and the relief portion 113 is used to avoid the transmission member 13. By providing the relief portion 113, the transmission member 13 can be effectively avoided under the premise that the support member 11 is relatively large, the range of movement of the transmission member 13 is expanded, and the transmission is better realized. Those skilled in the art can set the relief portion 113 to be a groove or a through hole according to actual needs.

[0040] Reference Figure 5 As shown, in some embodiments of the clamping device described in the utility model, a positioning groove 114 adapted to the object to be clamped is provided on the surface of the support member 11 located on the side close to the clamping member 12. A clamping gap is formed between the positioning groove 114 and the clamping portion 121 of the clamping member 12 rotated to the corresponding position to clamp the carrier. By providing the positioning groove 114, it is convenient to use the support member 11 to realize the hard limit of the object to be clamped, that is, the carrier; and the positioning groove 114 requires a small processing area and is easy to ensure flatness, thereby meeting the high flatness requirements when performing high-precision operations on the carrier.

[0041] Reference Figure 6 As shown, the clamping device of the present invention, in some embodiments, further includes a lifting member 20, which is configured to drive the object to be clamped relatively close to or relatively away from the clamping member 12. Those skilled in the art can set a specific lifting member 20 according to actual needs to achieve the driving of the carrier. Preferably, refer to Figure 7 As shown, the lifting member 20 includes a lifting component 21 and a lifting drive component 22, and the lifting drive component 22 is fixedly arranged. Preferably, the lifting drive component 22 is arranged as a cylinder. The lifting component 21 is connected to the piston rod of the lifting drive component 22. Preferably, a guide column is also provided to ensure structural stability and provide guidance. Preferably, a lifting hollow portion 211 is provided on the lifting component 21 to reduce weight and save energy. Preferably, a lifting positioning pin 212 is provided on the lifting component 21 to facilitate positioning of the carrier.

[0042] The utility model discloses a streamlined device, including a streamlined device and a clamping device described in any one of the above embodiments. The streamlined device belongs to the prior art, and the streamlined device is not shown in the attached drawings. The streamlined device is used to transport carriers and products, and its specific structure and principle are not described in detail. The clamping device is arranged on the streamlined device to clamp the carrier. The cooperation of the two can effectively reduce the CT of a single product and meet the demand for production efficiency. Since the streamlined device described in the utility model includes the clamping device described in the above embodiments, the beneficial effects thereof are also possessed by the streamlined device, which are not described in detail. Those skilled in the art can set the specific number of clamping devices according to actual needs. Preferably, a plurality of clamping devices are provided, and the plurality of clamping devices are arranged in sequence along the transportation direction of the streamlined device to facilitate operation. Preferably, the clamping units of each clamping device are correspondingly arranged on both sides of the streamlined device to avoid interfering with the transportation of the carrier.

[0043] Working principle:

[0044] When the carrier is transported to the corresponding workstation by the streamline device, the lifting component 21 lifts the carrier from the streamline device. After the carrier is lifted to the specified position, the piston rods of the driving cylinders 14 of the two clamping units 10 drive the corresponding transmission components 13 to rotate, so as to drive each clamping member 12 to rotate. During the rotation of the clamping member 12, it first contacts the buffer member 111 to reduce the force, and then contacts the carrier through the clamping pad 1211. With the cooperation of the clamping member 12 and the positioning groove 114, the carrier is clamped and positioned. At this time, the corresponding operating device operates on the product on the carrier. At the same time, the lifting component 21 descends to facilitate the transportation of other carriers with the streamline device.

[0045] After the operation is completed, the lifting component 21 rises and holds the carrier, and then the clamping member 12 rotates and releases the carrier under the cooperation of the driving cylinder 14 and the transmission component 13. Finally, the carrier returns to the streamline device with the lifting component 21 and continues to be transported with the streamline device.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
