[0039] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0040] Firstly, a device for picking up and placing items according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] refer to Figure 1 , Figure 1 FIG. 1 is a schematic diagram showing the structure of a device 100 for picking and placing items according to an embodiment of the present invention. Figure 1 As shown, the pick-and-place device 100 includes a chassis and a flip mechanism 200. A receiving chamber 110 is provided inside the chassis, and the flip mechanism 200 is disposed in the receiving chamber 110. The flip mechanism 200 is applied to the pick-and-place device 100 on an automated welding line. The pick-and-place device 100 serves as a workroom for the welding line to interact with an operator, and the operator performs pick-and-place operations in the pick-and-place device 100.

[0042] The turning mechanism 200 includes a lifting mechanism 210, a turning member 220 and a power assembly 230. The lifting mechanism 210 is used to lift the welded component 120 or lower the component to be welded 120. The turning member 220 is used to turn the component 120. The power assembly 230 is used to provide power.

[0043] The first end of the lifting mechanism 210 is located at the top of the chassis, and the second end of the lifting mechanism 210 passes through the top of the pick-and-place device 100 and extends into the accommodating chamber 110. That is, one end of the lifting mechanism 210 is outside the pick-and-place device 100, and the other end extends into the pick-and-place device 100. The lifting mechanism 210 can move along the vertical direction of the accommodating chamber 110. The flip member 220 is located in the accommodating chamber 110, one end of the flip member 220 is rotatably connected to the second end of the lifting mechanism 210, and the other end is used to connect with the welded component 120, and drive the welded component 120 to turn to the direction of the gate at a preset angle. The gate is the gate of the pick-and-place device 100, which is used for operators to enter or exit the pick-and-place device 100. One end of the power assembly 230 is located at the top of the chassis, and the other end of the power assembly 230 extends into the accommodating chamber 110 and is connected to the flip member 220, which is used to provide power for the flip member 220.

[0044] In the embodiment of the present invention, a lifting mechanism 210 and a flip member 220 connected to each other are arranged on the chassis of the pick-and-place device 100. When the lifting mechanism 210 rises upward, the flip member 220 drives the component 120 to rise. After the lifting mechanism 210 stops rising, the flip member 220 flips the component 120 and faces the gate of the pick-and-place device 100, so that the operator can perform the pick-up operation. Compared with the prior art in which the operator needs to bend over to reach into the pick-and-place device 100 and look up to pick up the item from the fetal membrane, the operator in the present invention can perform the pick-up operation by standing in front of the gate of the pick-and-place device 100, avoiding the operator from entering the pick-and-place device 100 to pick up the item, which is beneficial to reducing the operation risk of the operator on the welding line and facilitating improving the work efficiency of the operator.

[0045] In one embodiment of the present invention, Figure 1 As shown, the lifting mechanism 210 includes a lifting platform 211, a rotating shaft 212 is provided at the bottom of the lifting platform 211, and the flip member 220 is rotatably connected to the rotating shaft 212. In other words, the flip member 220 is rotatably connected to the lifting platform 211 through the rotating shaft 212. By setting the rotating shaft 212, when the lifting platform 211 drives the flip member 220 to rise to a preset height, for example, the preset height is 30 cm from the top of the device for picking and placing items 100. At this time, the flip member 220 can rotate around the rotating shaft 212 at a preset angle, for example, the rotation angle is 60°, which can avoid the operator from bending over to reach under the lifting platform 211 and looking up to pick up items, thereby facilitating the operator to pick up items.

[0046] In addition, in some other embodiments of the present invention, the preset height of the lifting platform 211 can be 20 cm from the top of the picking and placing device 100, and the rotation angle of the flip member 220 can also be 30° or 80°. The present invention does not make a sole limitation on the preset height of the lifting platform 211 and the rotation angle of the flip member 220.

[0047] In one embodiment of the present invention, Figure 1As shown, the turning member 220 includes a turning platform 221 and a grabbing member 222. A first connection point (not shown) and a second connection point (not shown) are provided on the top of the turning platform 221. The first connection point is located near the gate of the pick-and-place device 100, and the second connection point is located away from the gate. The first connection point is connected to the rotating shaft 212, and the second connection point is connected to the power assembly 230. The top of the grabbing member 222 is connected to the bottom of the turning platform 221, and the grabbing member 222 is used to grab the welded component 120. In other words, the lifting platform 211, the turning platform 221 and the grabbing member 222 are arranged in sequence from top to bottom. After the lifting platform 211 drives the turning platform 221 and the grabbing member 222 to rise to a preset height, the turning platform 221 drives the grabbing member 222 to rotate, thereby rotating the welded component 120 on the grabbing member 222 by a preset angle, so that the operator can operate the component 120.

[0048] Reference below Figure 2 , to illustrate an embodiment of the present invention. Figure 2 Shows Figure 1 The enlarged view of A in the figure. Figure 1 and Figure 2 As shown, the grabbing member 222 includes a grabbing plate 2221 and a grabbing power member 2222. The grabbing plate 2221 is connected to the turning table 221. The grabbing power member 2222 is arranged on the bottom surface of the grabbing plate 2221 and is used to connect with the component 120. By arranging the grabbing power member 2222 between the grabbing plate 2221 and the component 120, the component 120 can be grabbed onto the grabbing plate 2221. At the same time, the top of the grabbing plate 2221 is connected to the turning table 221, and the turning action and the grabbing action are respectively corresponded to two different components 120, so as to avoid the turning table 221 directly grabbing the welded component 120, and the service life of the turning table 221 can be extended.

[0049] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a positioning pin 2223 is provided on the bottom surface of the grab plate 2221, and a positioning hole is provided on the component 120. The grab plate 2221 and the component 120 are connected through the positioning pin 2223 and the positioning hole, and the positioning pin 2223 is used to fix the component 120. After the grab power member 2222 grabs the component 120 onto the grab plate 2221, the positioning pin 2223 on the grab plate 2221 can further fix the component 120, which is conducive to ensuring the stability of the grab member 222 structure.

[0050] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the grabbing power member 2222 is a cylinder. In one embodiment of the present invention, Figure 1As shown, a connecting shaft 223 is provided on the top surface of the grabbing plate 2221 , and the turning platform 221 is connected to the connecting shaft 223 , which helps to ensure the stability of the connection between the turning platform 221 and the grabbing member 222 .

[0051] In one embodiment of the present invention, Figure 1 As shown, the power assembly 230 is a flip electric cylinder 231. The flip electric cylinder 231 includes a push rod, one end of which is arranged outside the chassis, and the other end of the push rod passes through the lifting platform 211 in the accommodating cavity 110 and is connected to the flip member 220, so as to push the flip member to rotate. The flip electric cylinder 231 can push the flip member 220 to rotate.

[0052] In one embodiment of the present invention, Figure 1 As shown, the lifting mechanism 210 also includes a lifting hoist 213 and a lifting guide column 214. The first end of the lifting hoist 213 is located at the top of the chassis, and the second end of the lifting hoist 213 extends into the accommodating cavity 110 and is connected to the lifting platform 211, which is used to provide power for the lifting platform 211 to move in the vertical direction. The first end of the lifting guide column 214 is located at the bottom of the chassis, and the second end of the lifting guide column 214 penetrates the accommodating cavity 110 and extends to the top of the chassis. The lifting platform 211 and the flip member 220 are slidably connected to the lifting guide column 214. By setting the lifting guide column 214, the lifting mechanism 210 can be prevented from being offset during the lifting process, and the component 120 connected to the flip member 220 can be prevented from colliding with the inner wall of the pick-and-place device 100, which is conducive to ensuring the safety and integrity of the component 120 during the lifting process.

[0053] In one embodiment of the present invention, Figure 1 As shown, the top surface of the component 120 is provided with an upper membrane 130, and the bottom surface of the upper membrane 130 matches the top surface of the component 120. The component 120 is connected to the gripping member 222 through the upper membrane 130. By providing the upper membrane 130, it is possible to prevent the component 120 from colliding with the gripping member 222, which is conducive to ensuring the integrity of the component 120 during the welding line operation.

[0054] The working principle of the device for picking and placing items 100 according to the embodiment of the present invention will be described below in conjunction with its structure.

[0055] When the operator needs to take the component, the lifting hoist 213 on the welding line drives the lifting platform 211 to descend, and the flip member 220 and the grabbing member 222 connected to the lifting platform 211 descend together until the grabbing power member 2222 abuts against the welded component 120. The grabbing power member 2222 grabs the component 120 onto the grabbing plate 2221, and the positioning pin 2223 on the grabbing plate 2221 is inserted into the positioning hole on the component 120 for fixing.

[0056] The lifting hoist 213 on the welding line drives the lifting platform 211 to rise, and the turning platform 221 and the grabbing member 222 connected to the lifting platform 211 rise to a preset height together. The turning electric cylinder 231 drives the turning platform 221 to rotate around the rotating shaft 212, and the grabbing plate 2221 and the upper membrane 130 connected to the turning platform 221 also rotate, so that the component 120 on the upper membrane 130 is turned over, so that the operator on the welding line can pick up the component.

[0057] The pick-and-place device 100 of the embodiment of the present invention is provided with a lifting mechanism 210 and a flip member 220 connected to each other on the chassis of the pick-and-place device 100. When the lifting mechanism 210 rises upward, the flip member 220 drives the component 120 to rise to a preset height, and after the lifting mechanism 210 stops rising, the flip member 220 flips the component 120 and faces the gate of the pick-and-place device 100, so that the operator can stand in front of the gate of the pick-and-place device 100 to perform the pick-and-place operation. The present invention can prevent the operator from entering the inside of the pick-and-place device 100 to pick up the components, reduce the production risk of the welding line, and facilitate improving the work efficiency of the operator.
