[0024] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond those described herein, which can be apparent to those skilled in the art, without departing from the spirit and scope of the present application, and therefore the present application is not limited to the specific implementation disclosed below.

[0025] The present application provides a clamping device, and embodiments of the clamping device are as follows:

[0026] The following will be described in detail Figures 1 to 3 The present application provides a clamping device.

[0027] Please refer to Figure 1 , which shows a structure front view of a clamping device provided by an embodiment of the present application. The clamping device provided by the present application comprises a lifting device 1, a vertical mechanism 2, a clamping mechanism 3, and a support 4. The lifting device 1 is arranged at both ends of the support 4, and is used to lift the outer end 51 of each of the two sheets 5. The vertical mechanism 2 is arranged on the support 4, and is used to vertically raise the two sheets 5 whose outer ends are lifted by the lifting device 1. The clamping mechanism 3 is arranged below the support 4, and is used to clamp the two sides of the two sheets 5 vertically raised by the vertical mechanism 2.

[0028] It should be noted that the shape and size of the sheet 5 are uncertain. Some sheets 5 can be clamped by the clamping device provided by the embodiment of the present application, but due to the irregular shape of some sheets 5, the clamping device may not be able to easily lift the outer end or clamp the two sides of the sheet 5, thereby causing the clamping work of the clamping device to be unable to be completed smoothly. Therefore, in order to ensure the working efficiency and clamping effect of the clamping device, the sheet 5 clamped by the clamping device provided by the embodiment of the present application is preferably a strip-shaped sheet material with a fixed shape, i.e., a strip-shaped sheet.

[0029] The clamping device provided in the embodiments of the present application is specifically part of a strip-shaped sheet product production line, and the clamped strip-shaped sheet is a strip-shaped sheet product. The clamping device is specifically arranged at the joint of different parts of the production line, and is used to clamp the strip-shaped sheet product and transfer the product from one production line to another production line, so as to ensure that the different production line processing procedures of the strip-shaped sheet product can be smoothly connected. The strip-shaped sheet product includes bus bars, thin strip-shaped copper sheets, thin strip-shaped iron sheets, etc., and all these products must be capable of elastic deformation or plastic deformation. The present application specifically takes the bus bar as an example to describe in detail the working principle of the clamping device provided in the embodiments of the present application for clamping two sheets 5.

[0030] It should be noted that the two sheets 5 can be of the same type, such as both being bus bars or both being thin strip-shaped iron sheets. The two strip-shaped sheets 5 can also be of different types, such as one being a thin strip-shaped iron sheet and the other being a thin strip-shaped copper sheet. The two strip-shaped sheets 5 in the embodiments of the present application are both selected as bus bars.

[0031] The clamping device provided in the embodiments of the present application includes a support 4, which is used to mount and connect the necessary mechanisms and devices included in the clamping device. The support 4 includes a support base 41 and a support frame 42, and the lifting device 1 and the vertical mechanism 2 in the clamping device are both arranged on the support base 41. Specifically, the lifting device 1 is arranged at both ends of the support base 41, and below the support base 41 is a bus bar production line, which is provided with a plurality of fixing devices, each of which can detachably fix a bus bar placed along the same straight line. Specifically, the fixing device can detachably fix the inner ends 52 of the two bus bars, so that the two bus bars are symmetrical about the fixing device. The fixing device will always fix the two bus bars before the clamping mechanism 3 clamps the two bus bars, and will release the two bus bars after the clamping mechanism 3 of the clamping device completes the clamping action.

[0032] It should be noted that the bus bars are placed along the same straight line for the convenience of the work of the clamping mechanism. Of course, in specific operation, other ways of placing the two sheets 5 can also be adopted, but it is necessary to ensure that the outer ends of the two sheets 5 can be lifted by the lifting device 1 at the same time. When the fixing device is used to fix the two sheets 5, the inner ends 52 of the two sheets 5 can be vertically (at a right angle to the horizontal plane) fixed in the fixing device, and the other parts of the two sheets 5 are perpendicular (parallel to the horizontal plane) to the inner ends 52. After the two sheets 5 are vertically lifted by the vertical mechanism 2, the two sheets 5 are all perpendicular to the horizontal plane. Alternatively, the inner ends 52 of the two sheets 5 can be horizontally (parallel to the horizontal plane) fixed in the fixing device, and the other parts of the two sheets 5 are also parallel to the horizontal plane. After the two sheets 5 are vertically lifted by the vertical mechanism 2, the inner ends 52 of the two sheets 5 are still parallel to the horizontal plane, and the other parts of the two sheets 5 are perpendicular (perpendicular to the horizontal plane) to the inner ends 52.

[0033] In addition, double-sided adhesive tape can be used to horizontally fix the inner ends 52 of the two bus bars on the assembly line, or the inner ends 52 of the two bus bars can be fixed on the assembly line by using adhesive tape. However, the double-sided adhesive tape or the adhesive tape needs to have appropriate adhesive property, which can fix the horizontally placed two bus bars before the clamping device finishes the work, and can make the two bus bars easily separate from the double-sided adhesive tape or the adhesive tape after the clamping mechanism 3 clamps the bus bars. Of course, other methods can be used to detachably fix the bus bars, which are not limited herein. In the embodiment of the present application, the fixing device is used to horizontally fix the bus bars.

[0034] It should be noted that when the fixing device is arranged on the assembly line in the embodiment of the present application, the positions of the bracket base 41 and the lifting device 1 need to be considered. Specifically, the horizontal center line of the bus bar needs to be coplanar with the horizontal center line of the bracket base 41, and the vertical center line of the bus bar needs to be coplanar with the vertical center line of the bracket base 41. In the embodiment of the present application, the lifting device 1 is arranged at both ends of the bracket base 41, that is, one lifting device 1 is arranged at each end of the bracket base 41, and the two lifting devices 1 are symmetrically arranged at both ends of the bracket base 41 with the vertical center line of the bracket base 41 as the axis of symmetry. Specifically, the distance between each lifting device 1 and the vertical center line of the bracket base 41 is related to the length of the two bus bars to be lifted. Specifically, when the bus bars are located below the bracket base 41, the projections of the two lifting devices 1 on the horizontal plane where the bus bars are located are located outside the outer ends 51 of the two bus bars.

[0035] Please refer to Figure 2The lifting device 1 used in the embodiment of the present application is a gas blowing device, which includes a top portion 11 and a bottom portion 12, is used for passing gas, and can use gas to blow the outer end 51 of each of the two thin sheets 5 placed in the same line laterally. Specifically, the top portion 11 is arranged at the two ends of the bracket base 41, and the top portion 11 is a gas pipe capable of adjusting the flow of gas, which is used to input gas with different flow. The bottom portion 12 is a bent pipe, which is connected with the gas pipe and is used to provide the gas for blowing the outer end of the thin sheet, i.e., output the gas input by the gas pipe. The gas blowing device needs to be connected with a blowing device, which can be arranged inside the bracket 4, and the blowing device contains a control switch to control the flow of the blown gas. The blowing device is connected with the top portion 11 of the gas blowing device arranged at the two ends of the bracket base 41 respectively, and inputs the blown gas into the top portion 11, and then the gas pipe further adjusts and transmits the gas. Specifically, the gas pipe can further adjust the flow of the gas according to the requirement, and transmit the gas to the bent pipe, and the gas is output from the bent pipe. When the gas is output from the bent pipe, the gas flow is formed, and when the bus bar is transmitted by the flow line to the position directly below the bracket base 41 of the clamping device, the gas flow can lift the outer end of the two bus bars. That is, each lifting device 1 arranged at the two ends of the bracket base 41 lifts the outer end 51 of one thin sheet respectively, so that the outer end of each bus bar is spaced apart from the horizontal plane on which the bus bar is placed, thereby facilitating the subsequent vertical lifting work.

[0036] The flow of the gas required by the gas blowing device is related to the size and weight of the bus bar, and the greater the size and weight, the greater the flow of the gas required for lifting the bus bar. At this time, the control switch on the blowing device can be used to control the flow of the gas generated by the blowing device. In addition, the bottom portion 12 of the clamping device in the embodiment of the present application is a bent pipe, which can be suitable for the angle required by different thin sheets 5, which is the included angle between the horizontal plane on which the thin sheet 5 is placed and the bent pipe. Specifically, the greater the included angle between the bent pipe and the horizontal plane on which the thin sheet 5 is placed (the included angle is between 90-180 degrees), the lighter the thin sheet 5 that can be lifted by the gas flow output from the bent pipe. Therefore, when the clamping device provided in the embodiment of the present application is applied to other situations, the included angle between the bent pipe and the horizontal plane on which the thin sheet 5 is placed can be determined according to the weight of the thin sheet 5. In addition, for different thin sheets 5 with the same mass, the wider the thin sheet 5 at the two ends, the smaller the flow required. Therefore, the bending angle of the bent pipe can also be selected according to the width of the thin sheet 5 at the two ends. Among them, the two gas blowing devices can input different flows of gas at the same time to meet the situation that the two thin sheets 5 are different, and the two gas blowing devices can also lift the outer end 51 of each of the two thin sheets 5 respectively.

[0037] It should be noted that although the lifting device 1 of the clamping device provided in the embodiments of the present application is a gas lifting device, other devices can be used to replace the lifting device 1 when the clamping device is used in other situations. For example, a jacking device is arranged below the two ends of the support base 41, and two holes are arranged on the two sides of the position where the fixing device for fixing the two bus bars is arranged on the flow line. When the two bus bars are fixed on the fixing device along the same line in the transverse direction, the outer ends 51 of the two bus bars are just above the two holes. When the bus bars placed in the transverse direction are brought to below the support base 41 by the flow line, the jacking mechanism arranged below the two ends of the support base 41 is lifted from the two holes to jack up the outer ends 51 of the two bus bars. Thus, the outer ends 51 of the two bus bars are each spaced apart from the horizontal plane on which the bus bar is placed, thereby facilitating the subsequent vertical lifting work.

[0038] In addition, the lifting device 1 of the clamping device provided in the embodiments of the present application can be a claw lifting device in addition to the gas lifting device. The claw lifting device is arranged at the two ends of the support base 41, and the claw lifting devices at the two ends are symmetrical about the longitudinal axis of the support base 41. The claw lifting device comprises a connecting member and a claw. The connecting member is connected to the two ends of the support base 41, and the connecting member can be driven to move up and down by the claw driving device arranged in the support base 4. When the two bus bars placed in the transverse direction on the flow line are moved to below the support base, the connecting member at the top of the claw lifting device is extended downward, and the claw at the bottom of the claw lifting device can grab the outer ends 51 of the two bus bars. After the claw grabs the bus bar, the connecting member is driven to retract upward by the claw driving device, thereby driving the claw at the bottom and the outer ends 51 of the two bus bars to move upward. Thus, the outer ends 51 of the two bus bars placed in the transverse direction along the same line are lifted, and the outer ends 51 of the two bus bars are each spaced apart from the horizontal plane on which the bus bar is placed, thereby facilitating the subsequent vertical lifting work.

[0039] Please refer to Figure 1In this embodiment, after the clamping device lifts the outer ends 51 of the two horizontally placed strips 5 (busbars) along the same straight line by the lifting device 1, it is necessary to vertically shape the two busbars so that the clamping mechanism 3 can clamp the two sides of the busbars longitudinally. The vertical shaping mechanism of the clamping device provided in this embodiment is a vertical mechanism 2, which is set on the support base 41 and is used to vertically lift the two strips 5 (busbars) lifted by the lifting device 1. The vertical mechanism 2 includes two symmetrically arranged vertical sub-mechanisms 21, which are connected to the support base 41 and can rotate relative to the support base 41. Specifically, the two vertical sub-mechanisms are respectively set on the support base 41 by a rotating shaft 22, and the two vertical sub-mechanisms 21 are symmetrical about the longitudinal centerline of the support base 41. That is, the two vertical sub-mechanisms 21 are symmetrically and rotatably set on the support base 41 with the longitudinal centerline of the support base 41 as the axis of symmetry.

[0040] It should be noted that the two lifting sub-mechanisms 21 of the clamping device provided in this embodiment can rotate in an arc around the pivot 22 in the vertical plane where the transverse centerline of the support base 41 is located, driven by the driving device. When the two lifting sub-mechanisms 21 rotate toward the vertical plane where the longitudinal centerline of the support base 41 is located, the two lifting sub-mechanisms 21 can lift the manifold strips that are placed laterally along the same straight line and whose outer ends are lifted by the lifting mechanism 1. During the rotation of the two lifting sub-mechanisms 21 toward the vertical plane where the longitudinal centerline of the support base 41 is located, the two lifting sub-mechanisms 21 will first scoop up the two outer ends 51 of the two manifold strips that have a certain gap with the flow line plane, and then, as the two lifting sub-mechanisms 21 continue to rotate, the two lifting sub-mechanisms 21 will lift up the two manifold strips, thereby completing the vertical shaping of the two manifold strips. After the lifting mechanism 2 scoops up the two manifold strips, the lifting device 1 can stop working, that is, stop the gas input to the gas blowing device.

[0041] It should be noted that the two vertical sub-mechanisms 21 of the vertical shaping mechanism 2 of the clamping device provided in the embodiments of the present application include a vertical end 211 and a connecting end 212. The vertical end 211 is located below the bracket base 41 and is used to rotate the two thin pieces that are lifted to vertically raise the two thin pieces, i.e., the two strip-shaped thin pieces 5 (bus bars) that are lifted by the lifting device 1. The connecting end 212 is arranged on the bracket base 41 and is inside the bracket frame 42. A rotating shaft 22 that is installed on the bracket base 41 is arranged at the connection between the vertical end 211 and the connecting end 212 of the two vertical sub-mechanisms 21. The vertical end 211 of each of the two vertical sub-mechanisms 21 forms a respective angle (referred to as a rotating angle in the embodiments of the present application) with the end of the bracket base 41 on which the vertical end 211 is arranged. When the two vertical sub-mechanisms 21 rotate toward the vertical plane in which the longitudinal center line of the bracket base 41 is located, the rotating angle increases from small to large. The rotating process in which the rotating angle increases from small to large is referred to as inward rotation, and the rotating process in which the rotating angle decreases from large to small is referred to as outward rotation. That is, when the two vertical sub-mechanisms 21 vertically raise the two bus bars that are placed horizontally along the same straight line, the two vertical sub-mechanisms 21 move inward.

[0042] In order to ensure that the two vertical sub-mechanisms 21 of the clamping device provided in the embodiments of the present application can complete vertical shaping of the two ends of the bus bar and do not cause excessive deformation of the two ends of the bus bar, the clamping device is provided with a limiting mechanism 23 on the rotating shaft 22, which is used to limit the rotating range of the two vertical sub-mechanisms 21. Specifically, the limiting mechanism 23 can limit the rotating angle of the two vertical sub-mechanisms 21 to 50-90 degrees. When the rotating angle is 50 degrees, the vertical mechanism 2 is in an initial state, and when the rotating angle is 90 degrees, the vertical mechanism 2 completes vertical shaping of the bus bar. At this time, the angle between the bus bar and the assembly line is also 90 degrees. After the two vertical sub-mechanisms 21 vertically raise the two bus bars (complete vertical shaping), the angle between the two bus bars and the assembly line changes from 0 degrees to 90 degrees.

[0043] It should be noted that the limiting mechanism 23 includes a limiting groove 231 and a limiting piece 232. The limiting piece 232 is arranged at one end of the connecting end 212 connected with the vertical end 211. The limiting groove 231 is arranged at the connecting position of the connecting plate 45 and the connecting end 212, that is, the limiting groove 231 is arranged at the other end of the connecting end 212 away from the vertical end 211. The limiting groove 231 and the limiting piece 232 can respectively limit the two ends of the connecting end 212 to synchronously limit the rotation range of the vertical sub-mechanism 21. The limiting groove 231 is in the shape of a circular arc, the radius of the outer circular arc is the same as the length of the connecting end 212, and the radian angle of the circular arc is 40 degrees. In this way, the limiting groove 231 can limit the rotation angle of the two vertical sub-mechanisms 21 to be between 50-90 degrees. The limiting piece 232 is arranged on the bracket base 41, and a blocking piece is arranged on the bracket base 41, which can block the vertical sub-mechanism 21 to limit the rotation range of the vertical sub-mechanism 21 within a certain range, and the limiting effect of the limiting piece 232 on the vertical sub-mechanism 21 is the same. In order to drive the vertical mechanism 2, the clamping device provided in the embodiment of the application is provided with a vertical driving device 24 outside the bracket 4. The vertical driving device 24 is connected with the connecting end 212 through the slider 43, the connecting rod 44, the connecting plate 45 and the connecting end 212 arranged on the bracket 4 from top to bottom. When the vertical driving device 24 is started, the slider 43 can be driven to slide up and down, and the connecting rod 44 can be driven to extend and contract when the slider 43 slides up and down, and then the extension and contraction of the connecting rod 44 can further drive the connecting plate 45 to drive the connecting end 212 to rotate. Because the connecting end 212 and the vertical end 211 are an integral whole, the rotation of the connecting end 212 also means the rotation of the vertical sub-mechanism. When the vertical driving device 24 drives the slider 43 to slide up and down, the rotation of the connecting end 212 is driven, specifically, when the slider 43 slides upward, the connecting end 212 rotates away from the vertical plane where the longitudinal center line of the bracket base 41 is located, so that the vertical end 211 rotates toward the vertical plane where the longitudinal center line of the bracket base 41 is located. At this time, the two vertical sub-mechanisms 21 can vertically lift the two bus bars placed along the same straight line horizontally by the lifting device 1. Therefore, the vertical mechanism 2 can complete the vertical shaping work of the two bus bars.

[0044] In order to improve the application scope of the clamping device provided in the embodiment of the application, the vertical driving device 24 of the clamping device can be any one of a pneumatic cylinder driving device, a hydraulic cylinder driving device or an electric driving device. The specific form of the driving device can be determined according to the position where the clamping device is installed, and the requirements and working modes of the clamping device provided in the embodiment of the application.

[0045] Please refer to Figure 3Fig. 2 is a side view of a clamping device according to an embodiment of the present application. After the lifting device 1 lifts the two ends of the transversely placed strip-shaped sheet 5, the vertical shaping work of the two strip-shaped sheets 5 whose outer ends 51 are lifted by the lifting device 1 can be directly completed by the vertical mechanism 2. During the whole process, the lifting device 1 and the vertical mechanism 2 cooperate to complete the vertical work of the two strip-shaped sheets 5 at one time. Only after the vertical shaping of the two strip-shaped sheets 5 is completed, the clamping device according to the embodiment of the present application can clamp the two strip-shaped sheets 5. That is, the lifting work of the lifting device 1 and the vertical shaping work of the vertical mechanism 2 are both for the clamping of the two strip-shaped sheets 5 by the clamping mechanism 3.

[0046] Specifically, the clamping mechanism 3 includes two clamping sub-mechanisms 31 for clamping the two sides of the two strip-shaped sheets 5 that are vertically lifted by the vertical mechanism 2. Specifically, after the strip-shaped sheet 5 is vertically lifted, the two clamping sub-mechanisms 31 can clamp the two sides of the strip-shaped sheet 2 in the longitudinal direction. The clamping mechanism 3 is driven by a clamping driving device arranged outside the support 4, which can also be any one of a pneumatic cylinder driving device, a hydraulic cylinder driving device or an electric driving device.

[0047] When the vertical mechanism 2 and the clamping mechanism 3 cooperate, there are two cases. The first case is that after the vertical mechanism 2 vertically lifts the two strip-shaped sheets 5, it returns to the initial state immediately, and then the clamping mechanism 3 clamps the two sides of the two ends of the strip-shaped sheet 5. The second case is that after the vertical mechanism 2 vertically lifts the two strip-shaped sheets 5, the clamping mechanism 3 clamps the two sides of the two strip-shaped sheets 5 immediately, and then the vertical mechanism 2 returns to the initial state.

[0048] The clamping device according to the embodiment of the present application can independently and at one time complete the clamping of the two strip-shaped sheets 5 through the cooperation of the lifting action of the lifting device 1, the vertical action of the vertical mechanism 2 and the clamping action of the clamping mechanism 3, without relying on the assistance of human beings or other additional devices. Therefore, the clamping device has better clamping effect and accuracy and higher work efficiency. Moreover, the clamping device is easier to operate because it can independently and at one time complete the clamping of the strip-shaped sheet 5 without relying on the assistance of human beings or other additional devices.

[0049] It should be noted that the clamping device according to the embodiment of the present application is movably arranged on a workbench. Therefore, after the clamping device clamps the two strip-shaped sheets 5, the movement of the strip-shaped sheet 5 can be indirectly completed by moving the clamping device. Therefore, the strip-shaped sheet 5 (bus bar) can be transferred from one assembly line to another assembly line, which prepares for the subsequent processing of the bus bar.

[0050] Although the present application is disclosed with reference to the preferred embodiments above, it is not intended to limit the present application, and any person skilled in the art who learns the present application can make possible changes and modifications without departing from the spirit and scope of the present application, and the protection scope of the present application should be defined by the scope of the claims of the present application.
