Description

Technical Field

[0001] The present disclosure relates to the field of mechanical automation technology, and particularly to a clamping device and an automotive electronics production line. Background Art

[0002] During the assembly process of devices such as automotive electronics, some workpieces are used. The workpieces have mounting portions. When the workpieces are assembled with other components, the mounting portions need to face the set positions. For example, the workpiece can be a terminal wire harness. The circumferential surface of the terminal wire harness is usually a cylindrical surface. Terminals are connected to the ends of the wire harness. The terminals are usually metal sheet structures provided with through holes. During the assembly process of devices such as automotive electronics, the terminal wire harness needs to be clamped, and then components such as bolts are inserted into the through holes. The insertion direction of the bolts is certain. However, after the wire harness is clamped, the orientation of the through holes is random.

Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure.

[0038] In the description of the present disclosure, it should be noted that unless otherwise clearly specified and defined, when terms such as "installation", "connection", "coupling" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0039] See Figures 1 to 7 As shown, this embodiment provides a clamping device, which includes a first clamping mechanism 10, a second clamping mechanism 20 and a pressing part 50. The first clamping mechanism 10 includes a first conveyor belt 11, and the first conveyor belt 11 has a first surface 111. The second clamping mechanism 20 includes a second conveyor belt 21, and the second conveyor belt 21 has a second surface 211. The first surface 111 and the second surface 211 are used to contact a workpiece with an installation part to clamp the workpiece. The pressing part 50 is installed between the first clamping mechanism 10 and the second clamping mechanism 20. The pressing part 50 can contact the workpiece to adjust the angle between the workpiece and the conveying direction of the first conveyor belt 11. The first surface 111 and the second surface 211 can move in opposite conveying directions to drive the workpiece to rotate and make the installation part face the set position.

[0040] For the clamping device provided in this embodiment, when in use, the first surface 111 of the first conveyor belt 11 and the second surface 211 of the second conveyor belt 21 both contact the workpiece with the installation part, thereby clamping the workpiece. When the pressing part 50 contacts the workpiece, it can adjust the angle between the workpiece and the conveying direction of the first conveyor belt 11. At the same time, the first surface 111 and the second surface 211 move in opposite conveying directions, thereby driving the workpiece to rotate, so that the installation part faces the set position, which is convenient for assembly and thus improves the production efficiency.

[0041] In this embodiment, the workpiece can be a terminal wire harness, and the mounting portion is a terminal connected to the end of the terminal wire harness. When clamping the terminal wire harness, it is usually not clamped at the middle position of the terminal wire harness. When the terminal wire harness is picked up and in a suspended state, under the action of its own gravity, one end far from the clamping position will tilt downward. Correspondingly, one end close to the clamping position will tilt upward. The pressing portion 50 is located between the clamping position and the upward-tilting end of the terminal wire harness. After the pressing portion 50 contacts the terminal wire harness, the pressing portion 50 applies a downward pressure to the terminal wire harness, making the terminal wire harness in a horizontal state.

[0042] For the picking device provided in this embodiment, the first surface 111 and the second surface 211 can also move in the same direction to raise or lower the workpiece. When the workpiece rises, it can contact the pressing portion 50.

[0043] In other embodiments, the rising or falling of the workpiece can also be achieved by adjusting the different moving speeds of the first conveyor belt 11 and the second conveyor belt 21.

[0044] In some embodiments, the pressing portion 50 is rod-shaped, and the surface of the pressing portion 50 in contact with the workpiece can be a plane; the pressing portion 50 is located on the same side of the first picking mechanism 10 and the second picking mechanism 20. One end of the pressing portion 50 can be connected to the first picking mechanism 10, and the other end of the pressing portion 50 extends toward the second picking mechanism 20. The length direction of the pressing portion 50 is perpendicular to the conveying direction of the first conveyor belt 11.

[0045] Next, the specific structure of the first picking mechanism 10 will be described in detail.

[0046] In one embodiment, refer to Figure 3 As shown, the first picking mechanism 10 further includes a first mounting frame 12, a first driving mechanism 13, a first driving wheel 14, and a first auxiliary roller group. The first driving mechanism 13 and the first auxiliary roller group are both mounted on the first mounting frame 12. The first conveyor belt 11 is wound around the outside of the first driving wheel 14 and the first auxiliary roller group. The first driving mechanism 13 is in transmission connection with the first driving wheel 14 to drive the first conveyor belt 11 to move. Among them, the first driving mechanism 13 can be a motor, which can drive the first conveyor belt 11 to move in both forward and reverse directions. Exemplarily, refer to Figure 2 As shown, the first surface 111 can move along the arrow direction M and can also move along the arrow direction N.

[0047] The first mounting bracket 12 includes a first plate portion 121 and a second plate portion 122, and the first plate portion 121 is fixedly connected to the second plate portion 122; the first auxiliary roller set is installed between the first plate portion 121 and the second plate portion 122. The first auxiliary roller set includes a plurality of bearings 151, and the plurality of bearings 151 are spaced apart along the extending direction of the first surface 111 and installed on the first mounting bracket 12.

[0048] Exemplarily, blind holes are provided on the opposite surfaces of the first plate portion 121 and the second plate portion 122, a fixed shaft is installed between the two opposite blind holes, the inner ring of the bearing 151 is fixedly connected to the fixed shaft, and the outer ring of the bearing 151 can rotate around the axis of the fixed shaft, so that a rolling friction is formed between the outer ring and the first conveyor belt 11.

[0049] The first auxiliary roller set further includes a plurality of rollers 152, and the plurality of rollers 152 are spaced apart along the extending direction of the first surface 111 and installed on the first mounting bracket 12. Exemplarily, the roller 152 includes a pressing shaft and a rolling sleeve, the pressing shaft is fixedly pressed between the first plate portion 121 and the second plate portion 122, the rolling sleeve is sleeved on the pressing shaft, and the axial length of the rolling sleeve is less than the axial length of the pressing shaft, so as to ensure that the rolling sleeve can rotate relative to the pressing shaft, so that a rolling friction is formed between the rolling sleeve and the first conveyor belt 11.

[0050] Exemplarily, the pressing shaft of the roller 152 is installed between the first plate portion 121 and the second plate portion 122 by bolts, and counterbore holes are provided on both the first plate portion 121 and the second plate portion 122. Among them, for two adjacent rollers 152, the head of the bolt in one of the rollers 152 is located in the counterbore hole of the first plate portion 121, and the head of the bolt in the other roller 152 is located in the counterbore hole of the second plate portion 122. In this way, the counterbore holes on the first plate portion 121 and the second plate portion 122 can be dispersed, which is beneficial to ensuring the mechanical strength of the first plate portion 121 and the second plate portion 122.

[0051] In some embodiments, at least one roller 152 is provided between two adjacent bearings 151.

[0052] In some embodiments, at least one bearing 151 is provided between two adjacent rollers 152.

[0053] Of course, it can also be set that at least one roller 152 is provided between two adjacent bearings, and at the same time, at least one bearing is provided between two adjacent rollers 152.

[0054] In this embodiment, refer to Figure 3As shown, the roller 152 and the bearing 151 are both installed between the first plate portion 121 and the second plate portion 122, and the bearing 151 and the roller 152 are alternately arranged along the extension direction of the first surface 111. At the end of the first clamping mechanism 10, two bearings 151 can be continuously arranged.

[0055] In this embodiment, a plurality of bearings 151 and rollers 152 cooperate with each other to jointly support the first conveyor belt 11 . At the same time, rolling friction is formed between the bearings 151 and the rollers 152 and the first conveyor belt 11 to reduce resistance.

[0056] It should be noted that the arrangement of the rollers and the bearings can be selected according to actual conditions. In addition, the structural form of the first auxiliary roller group is not limited to the combination of rollers and bearings.

[0057] It should also be noted that the form of the first clamping mechanism is not limited to the above one. For example, the first clamping mechanism may also include a winding mechanism. One end of the first conveyor belt is connected to the winding shaft of the winding mechanism, and the other end can be connected to an energy storage mechanism (such as a tension spring). Exemplarily, when the winding mechanism drives the first conveyor belt to wind up, the tension spring is stretched, the first conveyor belt is straightened, and the first surface can move along the arrow direction M.

[0058] In one embodiment, the first clamping mechanism 10 further includes a first transmission mechanism, and the first drive mechanism 13 is connected to the first driving wheel 14 through the first transmission mechanism. By providing the first transmission mechanism, the power output shaft of the first drive mechanism 13 can be not colinear with the axis of the first driving wheel 14, thereby reducing the volume of the first clamping mechanism 10, making the overall structure more compact and suitable for a smaller operating space.

[0059] In some embodiments, the first transmission mechanism includes a gear transmission system and a transmission shaft 162 , the first driving mechanism 13 is transmission-connected to the gear transmission system, and the first driving wheel 14 is transmission-connected to the gear transmission system via the transmission shaft 162 .

[0060] For example, see Figure 5 As shown, the gear transmission system includes a driving gear 1611 and a driven gear 1612 , the power output shaft of the first driving mechanism 13 is transmission-connected with the driving gear 1611 , the driving gear 1611 is meshed with the driven gear 1612 , and the driven gear 1612 is transmission-connected with the first driving wheel 14 through the transmission shaft 162 .

[0061] See also Figure 6 As shown, the transmission shaft 162 is provided with a first bearing 163 , a second bearing 164 , a spacer ring 166 and a positioning ring 165 . The spacer ring 166 is located between the first bearing 163 and the second bearing 164 , and the positioning ring 165 is located between the first bearing 163 and the driven gear 1612 .

[0062] The first transmission mechanism further includes a bearing seat 167 which can be mounted on the first mounting bracket 12. Both the first bearing 163 and the second bearing 164 are mounted within the bearing seat 167. The outer rings of the first bearing 163 and the second bearing 164 are fixedly connected to the bearing seat 167, and the inner rings of the first bearing 163 and the second bearing 164 rotate together with the transmission shaft 162, thereby driving the first driving wheel 14 to rotate.

[0063] It should be noted that the form of the first transmission mechanism is not limited to the above one. For example, it can also be a worm and worm gear transmission system, which can be selected according to the actual situation.

[0064] In one embodiment, the first clamping mechanism 10 further includes an adjusting part 17. The first driving wheel 14 is connected to the adjusting part 17. The adjusting part 17 is movably mounted on the first mounting bracket 12 to adjust the distance between the first driving wheel 14 and the first auxiliary roller group.

[0065] In some embodiments, referring to Figure 5 As shown, the adjusting part 17 is fixedly connected to the bearing seat 167. Exemplarily, the adjusting part 17 and the bearing seat 167 are integrally formed. The adjusting part 17 is mounted on the first mounting bracket 12 by bolts (not shown in the figure). The adjusting part 17 is in the shape of a plate, and the adjusting part 17 is provided with an adjusting hole 171 which can be an oblong hole. Exemplarily, the number of the adjusting holes 171 can be two, which can enhance the fixing effect.

[0066] The first mounting bracket 12 is provided with a fixing part 172 which can be mounted on the side of the second plate part 122 away from the first plate part 121. The fixing part 172 is provided with a threaded hole. The bolt passes through the adjusting hole 171 and is connected to the threaded hole.

[0067] When it is necessary to adjust the position of the first driving wheel 14, the bolt can be loosened, and the adjusting part 17 can be moved along the length direction of the oblong hole to change the distance between the first driving wheel 14 and the first auxiliary roller group. After adjusting the position of the first driving wheel 14, the bolt is tightened again.

[0068] In this embodiment, the second clamping mechanism 20 further includes a second mounting bracket 22, a second driving mechanism 23, a second driving wheel 24 and a second auxiliary roller group. The second driving mechanism 23 and the second auxiliary roller group are both mounted on the second mounting bracket 22. The second conveyor belt 21 is disposed around the outside of the second driving wheel 24 and the second auxiliary roller group. The second driving mechanism 23 is in transmission connection with the second driving wheel 24 to drive the second conveyor belt 21 to move. The second clamping mechanism 20 further includes a second transmission mechanism. The second driving mechanism 23 is connected to the second driving wheel 24 through the second transmission mechanism.

[0069] In this embodiment, the structures of the first clamping mechanism 10 and the second clamping mechanism 20 are the same, and the moving speeds of the first surface 111 and the second surface 211 are the same, which is convenient for calculating the number of turns of the motor rotation and makes the operation more convenient.

[0070] The first surface 111 and the second surface 211 can move along the arrow direction M simultaneously to drive the workpiece to move in the direction close to the pressing part. At the same time, for workpieces that are not easy to be directly clamped in place, by moving the first surface 111 and the second surface 211 along the arrow direction M simultaneously, the workpiece can be moved to a position away from the end of the first clamping mechanism and the second clamping mechanism, and the clamping is more firm; the first surface 111 and the second surface 211 can also move along the arrow direction N simultaneously to drive the workpiece to descend. Of course, it can also be that one of the first surface 111 and the second surface 211 moves along the arrow direction M and the other moves along the arrow direction N.

[0071] In one embodiment, the clamping device further includes an image acquisition system and a control system. The image acquisition system is used to acquire the position of the workpiece, and the control system is used to calculate the angle that the installation part of the workpiece needs to rotate to face the set position according to the current position of the workpiece, and then obtain the number of turns that the motor needs to rotate, and then send an instruction to the motor. After the motor rotates the corresponding number of turns, the installation part can face the set position.

[0072] The image acquisition system can be a camera, and the control system can be a host computer. Exemplarily, the model of the host computer can be IPC 611 / 750W / AIMB 788G2 / NONI. The image acquisition system and the control system are both understandable to those skilled in the art and are well-known and easy to implement for those skilled in the art. Therefore, this embodiment will not be described in detail.

[0073] In one embodiment, the clamping device further includes a spacing adjustment mechanism. Both the first clamping mechanism 10 and the second clamping mechanism 20 are connected to the spacing adjustment mechanism. The spacing adjustment mechanism is used to adjust the distance between the first clamping mechanism 10 and the second clamping mechanism 20 to adjust the distance between the first surface 111 and the second surface 211.

[0074] By setting the spacing adjustment mechanism, not only can workpieces of different sizes (for example, terminal wire harnesses with different diameters) be clamped, but also the clamping force can be appropriately increased to prevent the workpiece from falling.

[0075] In a possible design, the spacing adjustment mechanism includes a jaw electric cylinder. The first jaw 311 of the jaw electric cylinder is connected to the first gripping mechanism 10, and the second jaw 312 of the jaw electric cylinder is connected to the second gripping mechanism 20. When the jaw electric cylinder operates, the first jaw 311 and the second jaw 312 can move towards each other or in opposite directions to drive the first gripping mechanism 10 and the second gripping mechanism 20 to move, thereby adjusting the distance between the first surface 111 and the second surface 211 to grip workpieces of different sizes.

[0076] It should be noted that the structure and working principle of the jaw electric cylinder should be understandable to those skilled in the art and are well-known and easy to implement for those skilled in the art. Therefore, this embodiment will not be described in detail.

[0077] In a second possible design, the spacing adjustment mechanism includes a jaw cylinder 31 and a limiting member. The first jaw 311 of the jaw cylinder 31 is connected to the first gripping mechanism 10, and the second jaw 312 of the jaw cylinder 31 is connected to the second gripping mechanism 20; the limiting member is used to adjust the distance between the first jaw 311 and the second jaw 312. When the jaw cylinder 31 is operating, the first jaw 311 and the second jaw 312 will switch between two work positions. In one work position, the distance between the first jaw 311 and the second jaw 312 is the largest, and in the other work position, the distance between the first jaw 311 and the second jaw 312 is the smallest. By setting the limiting member, the first jaw 311 and the second jaw 312 of the jaw cylinder 31 can be stopped at any position within the stroke range, thereby adjusting the distance between the first jaw 311 and the second jaw 312.

[0078] The jaw cylinder has stronger environmental adaptability and faster response speed, which is beneficial to improving production efficiency.

[0079] In some embodiments, as shown in Figure 3 the first mounting bracket 12 further includes a first connecting block 123. One end of the first connecting block 123 is fixedly connected to the first jaw 311, and the other end of the first connecting block 123 is fixedly connected to the second plate portion 122 of the first mounting bracket 12. Similarly, the second mounting bracket 22 further includes a second connecting block. One end of the second connecting block is fixedly connected to the second jaw 312, and the other end of the second connecting block is fixedly connected to the second plate portion 122 of the second mounting bracket 22.

[0080] In this second possible design, as shown in Figure 3 and Figure 4As shown, the limiting member includes a limiting block 32 and an inward adjustment bolt 33. The limiting block 32 is fixedly installed between the first jaw 311 and the second jaw 312. The inward adjustment bolt 33 is connected to the first jaw 311 to adjust the distance between the end of the inward adjustment bolt 33 close to the second jaw 312 and the limiting block 32. The end of the inward adjustment bolt 33 close to the second jaw 312 can abut against the limiting block 32 to limit the movement of the first jaw 311 in the direction close to the second jaw 312.

[0081] Exemplarily, the limiting block 32 can be fixedly installed on the cylinder block of the jaw cylinder 31. The first connecting block 123 is provided with a first threaded hole 1231, and the inward adjustment bolt 33 is threadedly connected to the first threaded hole 1231. By rotating the inward adjustment bolt 33, the distance between the end of the inward adjustment bolt 33 close to the second jaw 312 and the limiting block 32 can be adjusted, thereby adjusting the minimum distance between the first jaw 311 and the second jaw 312.

[0082] In this embodiment, an inward adjustment bolt 33 is also installed on the second connecting block, so that the actual moving strokes of the first jaw 311 and the second jaw 312 can be symmetrically adjusted.

[0083] When the end of the inward adjustment bolt 33 close to the second jaw 312 abuts against the limiting block 32, the first jaw 311 will no longer move in the direction close to the second jaw 312. At this time, a certain clamping force can be applied to the workpiece, but the workpiece will not be damaged.

[0084] In this second possible design, referring to Figure 3 and Figure 4 As shown, the limiting member further includes a fixing frame 34 and an opening adjustment bolt 35. The fixing frame 34 is installed on the cylinder block of the jaw cylinder 31. The fixing frame 34 is provided with a baffle, and the baffle is located on the side of the first jaw 311 away from the second jaw 312. The opening adjustment bolt 35 is connected to the baffle to adjust the distance between the opening adjustment bolt 35 and the first jaw 311. The end of the opening adjustment bolt 35 close to the second jaw 312 can abut against the first jaw 311 to limit the movement of the first jaw 311 in the direction away from the second jaw 312.

[0085] Exemplarily, the baffle is provided with a second threaded hole 341, and the opening adjustment bolt is threadedly connected to the second threaded hole 341. In this embodiment, the fixing frame 34 is provided with two baffles, namely a first baffle and a second baffle. Among them, the first baffle is located on the side of the first jaw 311 away from the second jaw 312, and the second baffle is located on the side of the second jaw 312 away from the first jaw 311, so that the actual moving strokes of the first jaw 311 and the second jaw 312 can be symmetrically adjusted.

[0086] By setting the opening adjustment bolt 35, the opening degree of the first clamping jaw 311 and the second clamping jaw 312 can be restricted. This can not only prevent interference between the first clamping jaw 311 and the second clamping jaw 312 and components such as the driving mechanism on their outer sides, but also improve work efficiency. Exemplarily, when releasing a workpiece, the first clamping jaw 311 and the second clamping jaw 312 do not need to open too wide, thus quickly completing the release of the workpiece and clamping the next workpiece.

[0087] In a third possible design, refer to Figure 7 As shown, the spacing adjustment mechanism includes a driving member and a first gear 41 and a second gear 42 that mesh with each other; the first clamping mechanism 10 is mounted on the first gear 41, and the second clamping mechanism 20 is mounted on the second gear 42. The driving member can drive the first gear 41 or the second gear 42 to rotate to adjust the distance between the first clamping mechanism 10 and the second clamping mechanism 20.

[0088] Exemplarily, the driving member can be a motor. When the driving member drives the first gear 41 to rotate, since the first gear 41 meshes with the second gear 42, the second gear 42 can rotate in the same direction as or in the opposite direction to the first gear 41. Exemplarily, when the driving member drives the first gear 41 to rotate in the direction of arrow A, the distance between the first clamping mechanism 10 and the second clamping mechanism 20 will increase, and when the driving member drives the first gear 41 to rotate in the direction of arrow B, the distance between the first clamping mechanism 10 and the second clamping mechanism 20 will decrease.

[0089] In one embodiment, refer to Figure 1 As shown, the clamping device further includes a housing 60. One ends of the first conveyor belt 11 and the second conveyor belt 21 are located inside the housing 60, and the other ends of the first conveyor belt 11 and the second conveyor belt 21 are located outside the housing 60 to facilitate contact with the workpiece and clamp the workpiece.

[0090] By providing the housing 60, it can protect the first clamping mechanism 10, the second clamping mechanism 20, and the spacing adjustment mechanism, and at the same time ensure the safety of the operator.

[0091] This embodiment also provides an automotive electronics production line, including the clamping device provided in this embodiment.

[0092] For the automotive electronics production line provided in this embodiment, due to the use of the clamping device provided in this embodiment, it can automatically adjust the angle and position of the workpiece so that the installation part faces the set position for easy assembly, thereby improving production efficiency.

[0093] In one embodiment, the automotive electronics production line further includes an automated mobile platform. The clamping device is mounted on the automated mobile platform, and the automated mobile platform drives the clamping device to move to the position where the workpiece is located to clamp the workpiece.

[0094] Exemplarily, the automated mobile platform may be, but is not limited to, a robotic arm or a multi-axis mobile platform.
