[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] See the image below for reference Figure 1-Figure 2 A lifting device 100 according to an embodiment of the present invention is described.

[0030] Combine Figure 1-Figure 2 As shown, the lifting device 100 according to the embodiment of the present invention can mainly include: a frame 10 and a lifting assembly 20, wherein the lifting assembly 20 includes a first lifting assembly 21 and a second lifting assembly 22, the first lifting assembly 21 and the second lifting assembly 22 are respectively arranged on both sides of the frame 10 in the left and right directions, the first lifting assembly 21 and the second lifting assembly 22 are relatively spaced apart, and a carrier plate transmission area 23 is defined between the first lifting assembly 21 and the second lifting assembly 22, the carrier plate transmission area 23 is suitable for placing and transmitting carriers, and the first lifting assembly 21 and the second lifting assembly 22 are selectively lifted and lowered synchronously in the up and down directions.

[0031] Specifically, in an embodiment of the present invention, the lifting assembly 20 includes two separately arranged first and second lifting assemblies 21 and 22, which can eliminate the platform lifting mechanism used in the prior art and create a safe working space within the lifting device 100. This allows the lifting device 100 to be used without a carrier being transferred, and the carrier transfer area 23 to be a safe area. When the lifting device 100 requires inspection and maintenance, personnel can stand directly between the first and second lifting assemblies 21 and 22. Even if the lifting device 100 is accidentally activated during operation, and the first and second lifting assemblies 21 and 22 begin to move up and down, no harm will be caused to the operator, thereby reducing the operational risks for maintenance personnel and improving the safety of the lifting device 100.

[0032] In addition, when any one of the first lifting assembly 21 and the second lifting assembly 22 fails, the faulty location can be inspected and repaired separately. Compared with the platform-type lifting mechanism in the prior art, the first lifting assembly 21 and the second lifting assembly 22 in the embodiment of the present invention have a simple structure, fewer parts, and a shorter time for disassembly and assembly during maintenance. In this way, the maintenance convenience of the lifting device 100 in the present invention can be improved, the maintenance difficulty can be reduced, and the maintenance time can be shortened, thereby reducing the downtime of the lifting device 100, making the utilization rate of the lifting device 100 higher, and further improving the production energy efficiency of the product.

[0033] Furthermore, the first lifting assembly 21 and the second lifting assembly 22 are respectively disposed on the left and right sides of the frame 10, so that the first lifting assembly 21 and the second lifting assembly 22 can support both the left and right sides of the carrier, thereby ensuring the balance of the carrier on the lifting device 100. The first lifting assembly 21 and the second lifting assembly 22 are disposed opposite each other on the left and right sides, thereby ensuring that the first lifting assembly 21 and the second lifting assembly 22 are arranged horizontally in the left and right directions. In this way, when the first lifting assembly 21 and the second lifting assembly 22 transport the carrier, the carrier can be kept horizontal, thereby facilitating the transportation of the carrier during the production process, making it suitable for automated production.

[0034] Furthermore, a carrier transfer area 23 is defined between the first lifting assembly 21 and the second lifting assembly 22. This provides a location for the carrier to be positioned during its transfer on the transfer lifting device 100, ensuring that the lifting device 100 can lift and transfer the carrier. During the transfer process, the first lifting assembly 21 and the second lifting assembly 22 selectively move up and down to drive the carrier to move in the vertical direction. After a carrier leaves the lifting device 100, the lifting device 100 can reset to transfer the next carrier, thereby enabling the lifting device 100 to operate repeatedly.

[0035] Furthermore, during the up and down movement of the first lifting assembly 21 and the second lifting assembly 22 , the first lifting assembly 21 and the second lifting assembly 22 always maintain synchronous lifting, thereby ensuring the stability of the carrier during the lifting and transmission process in the carrier transmission area 23 .

[0036] Combine Figure 1 and Figure 2 As shown, the first lifting assembly 21 and the second lifting assembly 22 both include a fixed module 24, a lifting motor 25 and a transmission component 26. The lifting motor 25 and the transmission component 26 are both arranged on the fixed module 24. The lifting motor 25 is transmission-connected to the transmission component 26 to drive the transmission component 26 to lift and lower in the up and down directions. A carrier plate transmission area 23 is defined between the transmission components 26 of the first lifting assembly 21 and the second lifting assembly 22.

[0037] Specifically, in the first lifting assembly 21 and the second lifting assembly 22, the fixed module 24 can provide a stable and reliable setting position for the lifting motor 25 and the transmission component 26 to complete the transmission and lifting of the carrier. The lifting motor 25 can output power, and the output power of the lifting motor 25 is transmitted to the transmission component 26, which can drive the transmission component 26 to operate. The transmission component 26 in the first lifting assembly 21 and the transmission component 26 in the second lifting assembly 22 are also spaced relative to each other in the left and right directions to define the carrier transmission area 23. In this way, under the drive of the lifting motor 25, the transmission components 26 of the first lifting assembly 21 and the second lifting assembly 22 can move up and down synchronously relative to the fixed module 24, so that the first lifting assembly 21 and the second lifting assembly 22 drive the carrier in the carrier transmission area 23 to move up and down.

[0038] Combine Figure 1 As shown, a slide 241 that can be raised and lowered in the up and down directions is provided on the fixed module 24, and the lifting motor 25 is connected to the slide 241 in a transmission manner to selectively drive the slide 241 to rise and fall in the up and down directions. The transmission component 26 is provided on the slide 241 and is located on a side adjacent to the first lifting assembly 21 and the second lifting assembly 22 in the left and right directions.

[0039] Specifically, the fixed module 24 is fixed to the frame 10 and can provide support for other structures in the first lifting assembly 21 and the second lifting assembly 22. The fixed module 24 is also provided with a slide 241, which can slide up and down relative to the fixed module 24. The lifting motor 25 is in transmission connection with the slide 241, so that the output power of the lifting motor 25 can be transmitted to the slide 241, causing the slide 241 to slide up and down relative to the fixed module 24. By changing the rotation direction of the lifting motor 25, the slide 241 can be selectively driven to slide up or down.

[0040] Furthermore, in an embodiment of the present invention, the transmission assembly 26 is disposed on the slide 241. This allows the slide 241 to drive the transmission assembly 26 to slide up and down relative to the fixed module 24 when it moves up and down, thereby enabling the first lifting assembly 21 and the second lifting assembly 22 to jointly drive the carrier to rise and fall. The transmission assembly 26 in the first lifting assembly 21 is disposed on the side of the slide 241 adjacent to the second lifting assembly 22, and the transmission assembly 26 in the second lifting assembly 22 is disposed on the side of the slide 241 adjacent to the first lifting assembly 21. In this way, the transmission assemblies 26 on both sides can be close to the carrier transmission area 23. In this way, the transmission assembly 26 can contact the carrier in the carrier transmission area 23, thereby ensuring the reliability of the transmission assembly 26 in transmitting the carrier.

[0041] Combine Figure 2As shown, the transmission component 26 includes a transmission member 261 and a transmission motor 262. The transmission member 261 is arranged on the slide 241 and extends in the front-to-back direction. A carrier plate transmission area 23 is defined between the transmission member 261 of the first lifting assembly 21 and the transmission member 261 of the second lifting assembly 22. The transmission motor 262 is connected to the transmission member 261 to selectively drive the transmission member 261 to transmit the carrier plate in the front-to-back direction.

[0042] Specifically, in an embodiment of the present invention, the transmission member 261 includes a transmission bracket 2611 and a transmission belt 2612. The transmission bracket 2611 extends forward and backward, and is provided with a rotating wheel at both ends. The transmission belt 2612 is sleeved on the rotating wheel. The transmission motor 262 is connected to one end of the transmission bracket 2611 in the front and rear directions, so that the transmission motor 262 can drive the rotating wheel to rotate, and the friction between the rotating wheel and the transmission belt 2612 drives the transmission belt 2612 to move in the front and rear directions. In this way, the transmission belt 2612 can drive the carrier plate to move in the front and rear directions to realize the transmission of the carrier plate.

[0043] Furthermore, a carrier transmission area 23 is defined between the transmission member 261 of the first lifting assembly 21 and the transmission member 261 of the second lifting assembly 22, so that the transmission member 261 can be close to the carrier transmission area 23 so that the transmission member 261 can contact the carrier in the carrier transmission area 23. After the carrier enters the carrier transmission area 23, under the action of the friction force of the conveyor belt 2612, the carrier can be driven from one end of the carrier transmission area 23 in the front-to-back direction into the carrier transmission area 23 until the carrier completely enters the carrier transmission area 23.

[0044] In the embodiment of the present utility model, combined with Figure 3 As shown, the production line has a lower level 300 and an upper level 200, and both upper and lower levels are equipped with conveyor belts. When the first lifting assembly 21 and the second lifting assembly 22 in the lifting device 100 descend to the same height as the lower level 300 conveyor belt, the lower level 300 conveyor belt and the transmission element 261 in the lifting assembly 20 operate simultaneously, so that the carriers on the lower level 300 conveyor belt can be smoothly transferred to the carrier plate transfer area 23 in the lifting device 100. Then, the first lifting assembly 21 and the second lifting assembly 22 rise, and the carrier plates can be raised to the same height as the upper level 200 conveyor belt. At this time, the upper level 200 conveyor belt and the transmission element 261 in the lifting assembly 20 operate simultaneously to smoothly transfer the carrier plates in the carrier plate transfer area 23 to the upper level 200 conveyor belt, thus realizing the lifting and lowering of the carrier plates in the production line. Similarly, the operation of the lifting device 100 can also transport the carrier plates on the upper level 200 conveyor belt to the lower level 300 conveyor belt.

[0045] Combine Figure 1 and Figure 2As shown, the lifting device 100 further includes a first stopper 30, which is disposed on the fixed module 24 and located on the upper and lower sides of the slide 241 to selectively limit the maximum vertical ascent and descent heights of the slide 241. Specifically, the fixed module 24 provides a stable and reliable location for the first stopper 30, ensuring that the first stopper 30 remains in a fixed position relative to the fixed module 24.

[0046] Furthermore, the slide 241 drives the transmission member 261 to slide up and down relative to the fixed module 24. First stoppers 30 are located on the upper and lower sides of the slide 241 to limit the position of the slide 241 relative to the fixed module 24. The first stopper 30 at the upper end of the fixed module 24 can limit the maximum ascent height of the slide 241, and the first stopper 30 at the lower end of the fixed module 24 can limit the maximum descent height of the slide 241. In this way, the maximum ascent and descent heights of the slide 241 relative to the fixed module 24 can be adjusted. In an embodiment of the present invention, the first stopper 30 can also adjust the origin position of the slide 241 in the vertical direction to ensure the accuracy of the raising and lowering of the slide 241.

[0047] Combine Figure 2 As shown, the rack 10 is provided with a slide rail 11, and the transmission assembly 26 is provided with a slider 263. The slider 263 is slidably provided on the slide rail 11 in the up-down direction. There are multiple slide rails 11, and the multiple slide rails 11 are spaced apart in the front-to-back direction of the rack 10. There are multiple sliders 263, and the multiple sliders 263 are provided in a one-to-one correspondence with the multiple slide rails 11. Specifically, the rack 10 is further provided with multiple slide rails 11, which extend up and down, and the transmission assembly 26 is provided with multiple sliders 263, and the multiple sliders 263 correspond one-to-one with the multiple slide rails 11, so that the multiple sliders 263 can selectively move up and down on the corresponding slide rails 11.

[0048] Furthermore, the transmission component 26 is connected to the slide rail 11 through the slider 263, which not only allows the transmission component 26 to slide up and down relative to the frame 10, but also allows the slide rail 11 to provide stable and reliable support for the transmission component 26, thereby improving the stability of the transmission component 26 sliding up and down.

[0049] Furthermore, in an embodiment of the present invention, the fixed module 24 is located in the middle position of the front-to-back direction of the transmission member 261, and at least one slider 263 and at least one slide rail 11 are provided at the front and rear ends of the fixed module 24. In this way, the transmission member 261 can be supported by multiple points in the front-to-back direction, so that the transmission member 261 can maintain balance during the lifting process. In this way, the position stability of the carrier plate during the transmission process can be improved, so that the lifting device 100 is suitable for automated production.

[0050] Combine Figure 1 and Figure 2 As shown, the lifting device 100 further includes a guide member 40, which includes a main plate 41 and guide wheels 42. The main plate 41 is disposed on the transmission assembly 26, and the guide wheels 42 are disposed on the main plate 41 and protrude toward the carrier transport area 23 to cooperate with the carrier guide on the transmission assembly 26. Specifically, the main plate 41 of the guide member 40 extends in the front-to-back direction and is disposed on the transmission assembly 26. This allows the guide member 40 to move up and down synchronously with the transmission assembly 26, ensuring that the guide member 40 always guides the carrier in the carrier transport area 23.

[0051] Furthermore, the guide wheel 42 is arranged on the main plate 41 and protrudes toward the carrier transmission area 23, so that the guide wheel 42 can be close to the carrier in the carrier transmission area 23, so that the guide wheel 42 is in contact with the carrier, thereby positioning the position of the carrier in the carrier transmission area 23.

[0052] In an embodiment of the present invention, there are multiple guide wheels 42, and the multiple guide wheels 42 are arranged at intervals in front and back on the main plate 41. In this way, when the carrier moves back and forth following the transmission member 261, the multiple guide wheels 42 can contact the carrier in turn, so that they can cooperate with the carrier guide on the transmission component 26 to prevent the position of the carrier on the transmission component 26 from being offset, which can improve the position accuracy of the carrier during the transmission process, and thus make the lifting device 100 of the present invention suitable for production automation.

[0053] Combine Figure 1 and Figure 2 As shown, the transmission components 26 on the first and second lifting assemblies 21, 22 are each provided with an anti-deviating sensor 27. Specifically, the anti-deviating sensor 27 can determine the height position of the first and second lifting assemblies 21, 22 in an automated production line. Thus, during the up and down movement of the first and second lifting assemblies 21, 22, the anti-deviating sensor 27 can ensure that the first and second lifting assemblies 21, 22 rise and fall synchronously, preventing either the first and second lifting assemblies 21, 22 from deviating during operation, thereby ensuring the operational reliability of the lifting assemblies 20.

[0054] Combine Figure 2As shown, one end of the transmission component 26 in the front-to-back direction is the carrier in-and-out end 264, and the transmission components 26 on the first lifting assembly 21 and the second lifting assembly 22 are both provided with an in-and-out plate sensor 265, a carrier deceleration sensor 266 and a carrier in-position sensor 267. The in-and-out plate sensor 265 is arranged adjacent to the carrier in-and-out end 264, and the carrier in-position sensor 267 is arranged adjacent to one end of the transmission component 26 in the front-to-back direction away from the carrier in-and-out end 264, and the carrier deceleration sensor 266 is arranged between the carrier in-position sensor 267 and the in-and-out plate sensor 265 and adjacent to the carrier in-position sensor 267.

[0055] Specifically, in this embodiment of the present invention, carriers enter and exit the transport assembly 26 in a front-to-back direction, i.e., one end of the transport assembly 26 in the front-to-back direction is a carrier entry and exit end 264. A carrier entry and exit sensor 265 is provided adjacent to the carrier entry and exit end 264 on the transport assembly 26 of the first and second lifting assemblies 21, 22. This allows for rapid and accurate detection of whether a carrier has entered the carrier transport area 23.

[0056] Furthermore, on the transmission components 26 of the first lifting assembly 21 and the second lifting assembly 22, a carrier in-position sensor 267 is provided at one end of the transmission component 26 in the front-to-back direction away from the carrier inlet and outlet end 264. After the carrier enters the carrier transmission area 23, it can quickly and accurately detect whether the carrier is transferred to the right position on the transmission component 26. This is conducive to ensuring the placement stability of the carrier on the lifting device 100 and preventing the carrier from falling during the lifting process.

[0057] Furthermore, on the transmission component 26 of the first lifting assembly 21 and the second lifting assembly 22, a carrier deceleration sensor 266 is provided between the carrier in-position sensor 267 and the in-and-out plate sensor 265 and adjacent to the carrier in-position sensor 267. When the carrier deceleration sensor 266 detects a carrier, the transmission component 26 can reduce the transmission speed to prevent the carrier from rushing out of the transmission component 26 due to excessive transmission speed. This can ensure the position accuracy of the carrier during the transmission process and is suitable for automated production.

[0058] In an embodiment of the present utility model, the in-and-out plate sensor 265, the carrier plate deceleration sensor 266 and the carrier plate in-position sensor 267 are all arranged on the main plate 41 to ensure the structural reliability of the in-and-out plate sensor 265, the carrier plate deceleration sensor 266 and the carrier plate in-position sensor 267 on the lifting assembly 20, thereby ensuring the working reliability of the in-and-out plate sensor 265, the carrier plate deceleration sensor 266 and the carrier plate in-position sensor 267.

[0059] Combine Figure 1 and Figure 2As shown, the lifting device 100 further includes a second stopper 50. One end of the transmission assembly 26 in the front-to-back direction is the carrier plate entry and exit end 264. The second stopper 50 is disposed at the other end of the transmission assembly 26 in the front-to-back direction to selectively limit the position of the carrier plate. Specifically, in the embodiment of the present invention, the carrier plate moves in and out of the transmission assembly 26 in the front-to-back direction, that is, one end of the transmission assembly 26 in the front-to-back direction is the carrier plate entry and exit end 264. The second stopper 50 is disposed at a position away from the carrier plate entry and exit end 264 in the front-to-back direction of the transmission assembly 26. The second stopper 50 can prevent the carrier plate from continuing to move in a direction away from the carrier plate entry and exit end 264. In this way, the placement of the carrier plate on the transmission assembly 26 can be avoided, and the failure of the carrier plate deceleration sensor 266 or the carrier plate in-position sensor 267 can be prevented, thereby preventing the carrier plate from rushing out of the transmission assembly 26 and falling. In this way, the reliability of the placement of the carrier plate on the transmission assembly 26 can be ensured.

[0060] In an embodiment of the present invention, the second limiter 50 includes but is not limited to a blocking cylinder, which is fixed on the transmission bracket 2611, thereby ensuring the structural reliability of the blocking cylinder and the blocking reliability of the blocking cylinder on the carrier plate.

[0061] According to the embodiments of the present invention, the lifting device 100 in this application can reduce operational risks and facilitate installation and maintenance. Compared with the structural design of the lifting mechanism in the prior art, the lifting device 100 in this application has a shorter maintenance time and a lower failure rate, which can reduce equipment maintenance costs and maintenance risks and is more suitable for automated production lines.
