[0079] The positioning assembly 200 of the present invention is used to position a carrier; specifically, when the carrier is transported to the positioning assembly 200, it can be positioned by the positioning assembly 200. Further, when the positioning assembly 200 is positioned, it can be driven to rise and fall by the lifting assembly 300 described below.

[0080] Specifically, the positioning assembly 200 of the present disclosure includes components such as a positioning plate 210 , a positioning pin 220 , and a vacuum suction cup 230 .

[0088] Figure 3 It is a schematic structural diagram of a jacking assembly according to one embodiment of the present disclosure. Figure 4 It is a structural schematic diagram of a partial structure of a jacking assembly according to an embodiment of the present disclosure.

[0090] The bottom plate 310 is disposed on the base 100 , and accordingly, the side plate 320 , the first slider 330 , the first slide rail 340 , the top plate 350 , the jacking mechanism and other components can be fixed on the bottom plate 310 , thereby, the jacking assembly 300 of the present disclosure can be formed as a whole.

[0091] The side plate 320 is disposed on the bottom plate 310 ; in the present disclosure, two side plates 320 are provided, and along the conveying direction of the carrier, the two side plates 320 are disposed on both sides of the conveying direction.

[0092] The first slider 330 is disposed on the side plate 320. In the present disclosure, the number of the first sliders 330 may be four, that is, two first sliders 330 may be disposed on each side plate 320. Specifically, the two first sliders 330 are respectively disposed at the two ends of the side plate 320 along the conveying direction.

[0093] The first slide rail 340 is slidably disposed on the first slider 330; specifically, each first slider 330 is provided with a first slide rail 340, and the first slide rail 340 is vertically or approximately vertically disposed, so that the first slide rail 340 of the present disclosure can move in a vertical direction or approximately in a vertical direction.

[0094] The top plate 350 is disposed at the upper end of the first slide rail 340; thus, when the first slide rail 340 slides relative to the first slider 330, the top plate 350 can generate a lifting motion. In the present disclosure, the positioning plate 210 can be fixed to the top plate 350, and accordingly, the positioning plate 210 can be lifted and lowered along with the lifting and lowering of the top plate 350.

[0095] A lifting mechanism is provided on the bottom plate 310 and is used for driving the top plate 350 to move up and down.

[0096] Specifically, the lifting mechanism includes: a driving device 301, a second slide rail 302, a second slider 303, a lifting plate 304, an idler wheel 305 and other components.

[0097] The driving device 301 is arranged on the base plate 310; in a preferred embodiment, the driving device 301 can be a cylinder, the cylinder body of the cylinder is fixed to the base plate 310, and the piston rod of the cylinder can output horizontal movement, that is, the cylinder is arranged horizontally or approximately horizontally.

[0098] The second slide rail 302 is disposed on the bottom plate 310 and is disposed in a horizontal direction. In the present disclosure, the second slide rail 302 is disposed in a conveying direction. Preferably, the extension direction of the second slide rail 302 is perpendicular to the extension direction of the first slide rail 340 .

[0099] The second sliding block 303 is slidably disposed on the second sliding rail 302 , and the driving device 301 is used to drive the second sliding block 303 to slide along the second sliding rail 302 .

[0100] The upper end of the lifting plate 304 is disposed on the top plate 350 , and the lower end of the lifting plate 304 is formed into a curved surface; preferably, the lower end of the lifting plate 304 includes an inclined plane.

[0101] The second slider 303 is provided with an idler wheel 305, and the idler wheel 305 cooperates with the lifting plate 304 to drive the lifting plate 304 to rise or fall. Specifically, the second slider 303 may be provided with an axis component, and the idler wheel 305 is provided on the axis component, and the idler wheel 305 can rotate freely on the axis component. When the second slider 303 is pushed out, the idler wheel 305 cooperates with the inclined plane to make the top plate 350 rise; in the opposite working process, when the second slider 303 is pulled back, the idler wheel 305 cooperates with the inclined plane to make the top plate 350 fall, thereby realizing the lifting and lowering of the top plate 350.

[0102] In the present disclosure, the number of the jacking plates 304 is two, and both of the two jacking plates 304 are located between the two side plates 320; accordingly, the number of the idler wheels 305 is also two, and each jacking plate 304 cooperates with an idler wheel 305, so that the jacking and positioning device of the present disclosure can be more stable during the lifting and lowering movement.

[0103] Therefore, the present invention can realize the lifting and lowering of the lifting plate through a horizontally arranged driving device, save space, and increase the load. It is suitable for production stations with small space and requiring product pressure maintenance or bonding processes.

[0104] In a preferred embodiment, the lifting assembly also includes a tension spring 360, one end of the tension spring 360 is connected to the top plate 350, and the other end of the tension spring 360 is connected to the bottom plate 310. The tension spring 360 is in a stretched state, so that the tension applied to the top plate 350 by the tension spring 360 can make the top plate 350 have a downward movement tendency. Accordingly, when the driving device 301 no longer provides the force to push out the second slider 303, the top plate 350 can move downward under the tension of the tension spring 360, thereby realizing the reset of the top plate 350.

[0105] In the present disclosure, along the conveying direction of the carrier, the blocking component 400 is located on the upstream side of the positioning component 200, and the non-return component 500 is located on the downstream side of the positioning component 200. Accordingly, the carrier can be blocked directly above the positioning component 200 by the blocking component 400, and the carrier can be prevented from moving backward by the non-return component 500.

[0106] like Figure 1 and Figure 2As shown, the blocking assembly 400 is disposed on one side of the positioning assembly 200 and is used to block the carrier; specifically, the blocking assembly 400 includes: a cylinder 410 and a blocking member 420 driven by the cylinder 410, wherein, when the positioning assembly 200 is located at the lowest position, the blocking member 420 is driven by the cylinder so that the upper end of the blocking member 420 is higher than the positioning assembly 200 (for example, higher than the upper surface of the positioning assembly 200); thereby, the blocking member 420 can block the carrier. On the other hand, when the positioning assembly 200 is located at the lowest position, the cylinder 410 can drive the blocking member 420 to a position lower than the positioning assembly 200, thereby the blocking member 420 will not hinder the continued transmission of the carrier.

[0107] In a specific embodiment, the base 100 may be provided with a support frame 430, the cylinder 410 is provided in the support frame 430, and the cylinder 410 is vertically provided. The support frame 430 is provided with a linear bearing, the blocking member 420 is slidably provided in the linear bearing, and the movement direction of the blocking member 420 is a vertical direction or a substantially vertical direction. The blocking member 420 is connected to the cylinder 410 and is driven by the cylinder 410 to generate a lifting action.

[0108] Figure 5 It is a schematic structural diagram of a check assembly according to one embodiment of the present disclosure. Figure 6 and Figure 7 It is a structural schematic diagram of a partial structure of a check assembly according to an embodiment of the present disclosure.

[0109] The non-return assembly 500 is disposed on the other side of the positioning assembly 200 and is used to prevent the carrier from returning.

[0110] Specifically, the non-return assembly 500 of the present disclosure includes components such as a mounting seat 510 and a non-return block 520 .

[0111] The mounting seat 510 can be fixed to the base 100 by means of a bracket and other components. The check block 520 can be rotatably disposed on the mounting seat 510 and has a first position and a second position, so that when the carrier is transported, the carrier can drive the check block 520 to move from the first position to the second position; when the carrier is transported, the check block 520 returns to the first position and checks the carrier.

[0112] Preferably, the mounting seat 510 can be formed with two ears, each of which is provided with a through hole, and one end of the check block 520 is provided with a through hole, and the hinge shaft 530 passes through the through hole of the ear and the through hole of the check block 520, so that the check block 520 can rotate relative to the mounting seat 510.

[0113] Furthermore, the other end of the check block 520 is formed as a sharp corner, and one end of the check block 520 can cooperate with the mounting seat 510 to limit the check block 520 to the first position, so that when the carrier contacts the check block 520, it can apply pressure to the check block 520, and the check block 520 is driven to the second position; when the carrier is disengaged from the mounting seat 510, the check block 520 can move from the second position to the first position under the elastic force of the return compression spring, and be limited to the first position by the mounting seat 510, thereby achieving stopping of the carrier.

[0114] When the positioning and lifting device disclosed in the present invention is in use, the carrier carrying the product flows to the top of the positioning and lifting device; the blocking component is actuated, the carrier is stopped, and the non-return component automatically pops up and locks; the proximity switch senses the material and receives a signal that the material is in place, the drive device extends, and at the same time pushes the idler wheel to move; the idler wheel remains tangent to the lifting plate, and when the idler wheel translates, the lifting plate rises, and the carrier will be lifted to the working position at this time; then, the vacuum suction cup absorbs the product to keep it in a stable state and the operation begins; after the operation is completed, the vacuum suction cup releases the carrier and the product, the drive device retracts, and the lifting plate descends.

[0115] Then block the movement of the component and stop blocking the carrier. The carrier will flow out of this workstation, and then block the movement of the component and wait for the next carrier.
