It can be seen that the fixed plate 2 supports and fixes the driving component 1 and the guide component 3, the driving component 1 drives the lifting plate 4 to move, the guide component 3 provides axial guidance for the lifting plate 4 during movement, the lifting plate 4 supports and fixes the pallet positioning component 5 and the secondary positioning component 6, the pallet positioning component 5 supports and limits the product pallet, the pallet positioning component supports and positions the product pallet, so that the product pallet is out of the streamline, and the secondary positioning component 6 supports and positions the product component, so that the product component falls off the limit of the product pallet, making it convenient to take and put the product component.

[0019] like Figures 1 to 2 In this embodiment, the drive assembly 1 is driven by a cylinder. This shows that the drive assembly 1 is driven by a cylinder because the cylinder drive has good stability, can provide continuous power output, and has good environmental adaptability, a relatively simple structure, and low procurement cost.

[0020] like Figure 2 In this embodiment, the pallet positioning assembly 5 includes a plurality of pallet support columns 50, a plurality of pallet positioning diamond pins 51, and a plurality of pallet positioning cylindrical pins 52. The plurality of pallet support columns 50, the plurality of pallet positioning diamond pins 51, and the plurality of pallet positioning cylindrical pins 52 are all fixedly fitted on the lifting plate 4. The pallet support columns 50, the pallet positioning diamond pins 51, and the pallet positioning cylindrical pins 52 are all limited in position with the product pallet. It can be seen that the lifting plate 4 supports and fixes the plurality of pallet support columns 50, the plurality of pallet positioning diamond pins 51, and the plurality of pallet positioning cylindrical pins 52. The pallet positioning diamond pins 51 and the pallet positioning cylindrical pins 52 both play a role in positioning the product pallet. The pallet support columns 50 support and limit the bottom of the product pallet. The pallet positioning diamond pins 51 and the pallet positioning cylindrical pins 52 both connect, cooperate, and position the product pallet.

[0021] like Figure 2In this embodiment, the guide assembly 3 includes a plurality of guide rods 30, a plurality of linear bearings 31 and a pair of linkage plates 32. The two guide rods 30 near one end of the fixed plate 2 are linked together through the linkage plate 32. A buffer recess 33 is provided on the linkage plate 32. The two ends of the guide rod 30 are respectively limited and matched with the fixed plate 2 and the lifting plate 4. The linear bearing 31 is limited and matched on the fixed plate 2. The guide rod 30 and the linear bearing 31 are slidably matched. It can be seen that the fixed plate 2 supports and fixes the linear bearings 31, and the linear bearings 31 reduce the friction coefficient and guide the guide rod 30 during the movement process, so that the guide rod 30 maintains a stable position and direction during the movement. The guide rod 30 guides the movement of the lifting plate 4, and the linkage plate 32 provides a pair of guide rods 30 with horizontal linkage, so that the spacing ensures the horizontality of the lifting plate 4 and the product pallet, reducing the error caused by different heights. The linkage plate 32 supports and fixes the buffer block 33, and the buffer block 33 plays a buffering role when cooperating with the length adjustment shaft 20, reducing the misalignment error caused by severe collision.

[0022] like Figure 1 In this embodiment, the lifting mechanism is provided with a drag chain 9, the ends of which are respectively limited and engaged with the fixed plate 2 and the lifting plate 4. The drag chain 9 is limited and engaged with components such as the wiring channel of the lifting mechanism. Thus, the drag chain 9 serves to limit and protect components such as the wiring channel of the lifting mechanism, preventing cables, wires, etc. from being damaged due to movement or friction when the mechanical equipment is in operation.

[0023] like Figure 3In this embodiment, the secondary positioning assembly 6 includes a secondary positioning horizontal plate 60, a plurality of horizontal adjustment screws 61, a secondary positioning quick-change plate 62 and a plurality of quick positioning pin sleeves 63. The secondary positioning horizontal plate 60 is limited and matched with the lifting plate 4 through the horizontal adjustment screw 61. A plurality of positioning pins are provided on the secondary positioning horizontal plate 60. The secondary positioning quick-change plate 62 is limited and matched on the secondary positioning horizontal plate 60 through the quick positioning pin sleeve 63. A plurality of secondary positioning cylindrical pins 64, a plurality of secondary positioning diamond pins 65 and a plurality of secondary positioning support columns 66 are provided on the secondary positioning quick-change plate 62. The secondary positioning cylindrical pins 64, the secondary positioning diamond pins 65 and the secondary positioning support columns 66 are limited and matched with the product components on the product tray. It can be seen that the lifting plate 4 supports the secondary positioning horizontal plate 60, and the horizontal adjustment screw 61 limits the secondary positioning horizontal plate 60. At the same time, rotating the horizontal adjustment screw 61 can adjust the secondary positioning horizontal plate 60 to eliminate the horizontal error caused by the product pallet processing. The quick positioning pin sleeve 63 and the positioning pin limit the secondary positioning quick-change plate 62 on the secondary positioning horizontal plate 60. The secondary positioning quick-change plate 60 supports and fixes several secondary positioning cylindrical pins 64, several secondary positioning diamond pins 65 and several secondary positioning support columns 66. The secondary positioning cylindrical pins 64 and several secondary positioning diamond pins 65 position the product components, and several secondary positioning support columns 66 support and limit the bottom surface of the product components.

[0025] like Figure 3 In this embodiment, a sensor 67 is provided on the secondary positioning horizontal plate 60, and the sensor 67 cooperates with the secondary positioning quick-change plate 62. Thus, the secondary positioning horizontal plate 60 supports and limits the sensor 67, and the sensor 67 cooperates with the secondary positioning quick-change plate 62 to identify different secondary positioning quick-change plates 62 and send an identification signal to an external device.

[0026] like Figure 3In this embodiment, a plurality of regular holes are provided on the secondary positioning quick-change plate 62. Therefore, the purpose of providing the secondary positioning quick-change plate 62 with the plurality of regular holes is to reduce the weight of the secondary positioning quick-change plate 62, thereby reducing the driving force of the drive assembly 1, thereby ensuring sufficient strength and reducing costs.

[0027] like Figure 3 In this embodiment, the support height of the secondary positioning cylindrical pin 64, the secondary positioning diamond pin 65, and the secondary positioning support column 66 is 2-3 mm higher than the tray support column 50. Thus, the secondary positioning cylindrical pin 64, the secondary positioning diamond pin 65, and the secondary positioning support column 66 can lift the product component to a height of 2-3 mm from the product tray, allowing the product component to fall off the product tray's limit position, while also facilitating the removal and placement of the product component.

[0028] In this embodiment, the working principle of the utility model is as follows:

[0029] like Figures 1 to 3 As shown, after the product pallet carries the product components to the designated position through the assembly line, the drive assembly 1 lifts the lifting plate 4 through the guide rod 30 and the linear bearing 31, the pallet positioning diamond pin 51 and the pallet positioning cylindrical pin 52 position the product pallet, and the pallet support column 50 supports the bottom of the product pallet, so that the product pallet is positioned and separated from the assembly line.

[0030] While the product tray is being positioned and lifted, the secondary positioning horizontal plate 60, the secondary positioning quick-change plate 62, the secondary positioning cylindrical pin 64, the secondary positioning diamond pin 65 and the secondary positioning support column 66 on the lifting plate 4 together lift the product components on the product tray, so that the product components fall off the product tray by 2 to 3 mm.

[0031] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
