[0053] Although the existing manipulator assembly structure can perform the operation of the picking tray, in order to enable the mechanical claws to grasp the tray from both sides of the tray, a relatively large activity space needs to be reserved on both sides of the tray, resulting in a relatively large stacking space for the tray. In addition, due to the structural characteristics of the mechanical claws, the existing manipulator assembly is not suitable for picking up trays with irregular planes or trays made of plastic materials, and thus is subject to certain limitations.
[0054] In view of the above, the present application provides a fixture to solve the above problems.
[0055] Please refer to Figure 1 , which is a schematic structural diagram of the fixture 100 provided by the embodiment of the present application.
[0056] Specifically, the fixture 100 includes a fixed component 10 and a moving component 20. The fixed component 10 includes a bracket 11, a support plate 12, a pressing member 13, and a first driving member 14. The support plate 12 is disposed at the bottom of the bracket 11 and extends along the first direction X. The support plate 12 is used for carrying the tray 300 (as Figure 2 shown). The pressing member 13 is movably disposed at the top of the bracket 11. The first driving member 14 is connected to the pressing member 13. The first driving member 14 is used to drive the pressing member 13 to move up and down along the second direction Z. The pressing member 13 is used to press the tray 300. The moving component 20 includes a hook portion 21, a second driving member 22, and a third driving member 23. The second driving member 22 and the third driving member 23 are both disposed on the bracket 11. The second driving member 22 is connected to the hook portion 21. The second driving member 22 is used to drive the hook portion 21 to move back and forth along the first direction X, so as to drive the hook portion 21 to pull the tray 300 back to the support plate 12. The third driving member 23 is connected to the second driving member 22. The third driving member 23 is used to drive the hook portion 21 to move along the second direction Z through the second driving member 22.
[0057] For example, the first driving member 14, the second driving member 22, and the third driving member 23 can all be driving cylinders, and the present application places no restrictions thereon.
[0058] In some embodiments, the working principle of the fixture 100 is as follows: (1) As Figure 2 shown, the fixture 100 moves to a specified position, causing the support plate 12 to move below the tray 300. (2) As Figure 3 shown, the second driving member 22 drives the hook portion 21 to move along the first direction X, causing the hook portion 21 to move below the tray 300 and be located at an outer position of the tray 300. (3) As Figure 4 shown, the third driving member 23 drives the hook portion 21 to rise along the second direction Z, causing the hook portion 21 to hook the tray 300. (4) As Figure 5 shown, the second driving member 22 drives the hook portion 21 to return to its initial state along the first direction X, and the hook portion 21 pulls the tray 300 back to the support plate 12. The first driving member 14 drives the pressing member 13 to descend along the second direction Z, and the pressing member 13 presses against the tray 300, thereby achieving clamping of multiple trays 300.
[0059] The fixture 100 of the present application uses the hook portion 21 to pull the tray 300 back to the support plate 12, which can achieve the picking of the tray 300 in a relatively small moving space, improving the adaptability; using the pressing member 13 to press against the tray 300 can fix the tray 300 and prevent damage to the tray 300 caused by shaking or dropping during movement. On this basis, the fixture 100 can pick multiple trays 300, improving the picking efficiency of the trays 300; using the driving of the first driving member 14, the second driving member 22, and the third driving member 23 realizes automated picking and effectively reduces production costs.
[0060] Combined with Figure 6 shown, in some embodiments, the hook portion 21 includes a support rod 211 and a hook block 212. The support rod 211 is arranged at the end of the second driving member 22 along the first direction X, and the hook block 212 is fixed to the end of the support rod 211 along the second direction Z.
[0061] In some embodiments, the hook block 212 is made of a flexible material.
[0062] In the above embodiments, the hook block 212 made of a flexible material can pull back the tray 300 when the tray 300 is horizontally inclined at a certain angle, with strong adaptability.
[0063] In some embodiments, the second driving member 22 includes a cylinder body 221, a plurality of pistons 222, a plurality of piston rods 223, and a connecting block 224. The cylinder body 221 is fixed to the bracket 11 along the first direction X. The plurality of pistons 222 are arranged inside the cylinder body 221. The piston rods 223 are movably connected to the pistons 222. The connecting block 224 is arranged at the ends of the plurality of piston rods 223. The support rod 211 is fixed to the connecting block 224 along the first direction X.
[0064] In the above embodiments, the second driving member 22 adopts a three-rod cylinder. Since the three-rod cylinder is driven by three piston rods 223, it has high stability and will not accidentally shake or vibrate during the process of the hook portion 21 pulling back the tray 300. The three-rod cylinder can perform more precise position control according to actual needs. The design of the three-rod cylinder can effectively reduce the wear and vibration of the cylinder body 221, reduce the failure rate of the cylinder body 221, and has a longer service life. The maintenance of the three-rod cylinder is relatively simple and can quickly resume normal operation.
[0065] Combined with Figure 1 As shown in the figure, in some embodiments, the fixing assembly 10 further includes two guide plates 15. The two guide plates 15 are respectively arranged on both sides of the support plate 12 along the second direction Z and extend upward.
[0066] In some embodiments, the two guide plates 15 are respectively opened to both sides of the support plate 12.
[0067] In the above embodiments, during the process of the hook portion 21 pulling back the tray 300 to the support plate 12, the tray 300 is guided and positioned by the guide plates 15, which facilitates accurately pulling back the tray 300 to the support plate 12, improves the positioning accuracy, and prevents the tray 300 from being damaged due to dropping during the pulling-back process.
[0068] In some embodiments, the fixing assembly 10 further includes two fixing plates 16. The two fixing plates 16 are respectively arranged on both sides of the support plate 12 along the second direction Z and extend upward. The guide plates 15 are inclinedly arranged at the ends of the fixing plates 16.
[0069] In the above embodiments, the fixing plates 16 are used to limit both sides of the tray 300, thereby realizing the "clamping" of both sides of the tray 300 and preventing damage to the tray 300 caused by shaking or dropping of multiple stacked trays 300 during the pulling-back process.
[0070] Combined with Figure 1 As shown in the figure, in some embodiments, the pressing member 13 includes a pressing plate 131 and a baffle plate 132. The pressing plate 131 is arranged at the end of the second driving member 22. The baffle plate 132 is arranged on one side of the pressing plate 131 along the first direction X and extends downward.
[0071] In the above embodiments, the pressing plate 131 can press against the tray 300, and the baffle 132 can limit the tray 300 to prevent the tray 300 from sliding under the action of inertia.
[0072] In some embodiments, the fixture 100 further includes a first sensor 30, a second sensor 40, and a controller (not shown in the figure). The first sensor 30 is disposed on the bracket 11 along the first direction X, and the second sensor 40 is disposed at the end of the support plate 12 along the first direction X. The controller is electrically connected to the first driving member 14, the second driving member 22, the third driving member 23, the first sensor 30, and the second sensor 40.
[0073] In the above embodiments, the first sensor 30 and the second sensor 40 detect the current position of the tray 300, and then the controller controls the first driving member 14, the second driving member 22, or the third driving member 23 to perform driving work according to the detection results of the first sensor 30 and the second sensor 40, realizing the automation of the clamping of the tray 300 and improving the clamping accuracy and efficiency.
[0074] Combined Figure 2 As shown, in some embodiments, the fixture 100 further includes a manipulator 200. The bracket 11 is connected to the manipulator 200, and the manipulator 200 is electrically connected to the controller.
[0075] In the above embodiments, the manipulator 200 is controlled by the controller and can move the fixture 100 to a specified position.
