[0025] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0026] Reference Figures 1 to 3 An example of the present invention provides a product conveying device, which includes a transverse movement mechanism 100 and a lifting mechanism 200.

[0027] Among them, the transverse movement mechanism 100 includes a base 110 and a first driving member 120 for driving the base 110 to move horizontally. The lifting mechanism 200 includes a frame 210, a first material rack 220 and a second material rack 230 arranged on both sides of the frame 210, a second driving member 240 for driving the first material rack 220 to move up and down, and a synchronization component 250 connecting the first material rack 220 and the second material rack 230. The synchronization component 250 is used to drive the second material rack 230 to descend when the first material rack 220 rises, and to drive the second material rack 230 to rise when the first material rack 220 descends. The frame 210 is set on the base 110, and the first material rack 220 and the second material rack 230 are both used to carry material magazines.

[0028] Specifically, the synchronization assembly 250 includes two synchronization wheels 251 and a synchronization belt 252 wound around the two synchronization wheels 251. The two synchronization wheels 251 are respectively rotatably connected to the frame 210. One of the synchronization wheels 251 is located directly above the other synchronization wheel 251. The first material rack 220 and the second material rack 230 are both fixed to the synchronization belt 252 through a connecting block 253.

[0029] During production, the first driving member 120 first drives the base 110 to translate to the specified position, so that the base 110 drives the entire lifting mechanism 200 to translate to the specified position. At this time, the first material rack 220 is at the bottom and the second material rack 230 is at the top. Then, the material magazine containing the product is placed on the first material rack 220, and the second driving member 240 drives the first material rack 220 to rise, so that the material magazine on the first material rack 220 is raised to a set height, which is convenient for the mechanism of the next process to take the material. At the same time, the synchronous belt 252 drives the second material rack 230 to descend, so that the material magazine containing the product is placed on the second material rack 230, thereby realizing the alternating lifting of the first material rack 220 and the second material rack 230, thereby improving work efficiency. Moreover, the second material rack 230 can provide a counterweight, thereby balancing the weight of the first material rack 220, reducing the load of the second driving member 240 when driving the first material rack 220 to rise and fall, reducing the energy consumption and wear of the second driving member 240, and increasing the service life of the second driving member 240.

[0030] In some preferred embodiments, the first driving member 120 includes a base plate 121, a first motor 122, a first screw 123, a first nut 124, a first nut seat 125 and two first bearing seats 126. The two first bearing seats 126 are fixedly mounted on the base plate 121, the two ends of the first screw 123 are respectively rotatably connected to the two first bearing seats 126, the main shaft of the first motor 122 is connected to one end of the first screw 123, the first nut 124 is threadedly connected to the first screw 123, the first nut 124 is fixedly connected to the first nut seat 125, and the first nut seat 125 is connected to the base 110.

[0031] It can be understood that the first motor 122 drives the first screw 123 to rotate, and the first screw 123 drives the first nut 124 to move along the axial direction of the first screw 123, thereby driving the base 110 to translate, thereby improving the positioning accuracy of the base 110 and improving the accuracy and stability of the base 110 during translation. At the same time, the first screw 123 has good rigidity and can withstand a larger load.

[0032] Furthermore, a first linear guide rail 127 is provided between the bottom plate 121 and the base 110. The length direction of the first linear guide rail 127 extends along the axial direction of the first lead screw 123. The first linear guide rail 127 can provide guidance for the base 110, thereby improving the accuracy and stability of the base 110 during translation.

[0033] In some preferred embodiments, the second driving member 240 includes a vertical plate 241, a second motor 242, a second lead screw 243, a second nut 244, a second nut seat 245 and two second bearing seats 246. The two second bearing seats 246 are fixedly mounted on the vertical plate 241, and the two ends of the second lead screw 243 are respectively rotatably connected to the two second bearing seats 246. The second lead screw 243 is vertically arranged, and the main shaft of the second motor 242 is connected to one end of the second lead screw 243. The second nut 244 is threadedly connected to the second lead screw 243. The second nut 244 is fixedly connected to the second nut seat 245, and the second nut seat 245 is connected to the first material rack 220.

[0034] It can be understood that the second motor 242 drives the second screw 243 to rotate, and the second screw 243 drives the second nut 244 to move along the axial direction of the second screw 243, thereby driving the first material rack 220 to rise or fall, thereby improving the positioning accuracy of the first material rack 220 and improving the accuracy and stability of the first material rack 220 during lifting and lowering.

[0035] Furthermore, a second linear guide rail 260 is arranged between the first material rack 220 and the frame 210. The second linear guide rail 260 is arranged vertically. The second linear guide rail 260 can provide guidance for the first material rack 220, thereby improving the accuracy and stability of the first material rack 220 when it is lifted or lowered.

[0036] Similarly, a third linear guide rail 270 is arranged between the second material rack 230 and the frame 210. The third linear guide rail 270 is arranged vertically. The third linear guide rail 270 can provide guidance for the second material rack 230, thereby improving the accuracy and stability of the second material rack 230 during lifting and lowering.

[0037] Reference Figure 4 In some preferred embodiments, the first material rack 220 has the same structure as the second material rack 230. The first material rack 220 includes a frame 221 and a plurality of support plates 222 arranged in the frame 221. The plurality of support plates 222 are horizontally arranged in sequence from top to bottom. The plurality of support plates 222 can carry more material magazines, thereby improving the utilization rate of the first material rack 220 and improving production efficiency.

[0038] Furthermore, a door body 223 is hinged on one side of the frame 221, and a door lock 224 is provided between the frame 221 and the door body 223. The door body 223 can be opened or closed by operating the door lock 224, thereby preventing the material boxes on the first material rack 220 and the second material rack 230 from shifting or falling during the lifting process, thereby ensuring stability during transportation.

[0039] Specifically, the door lock 224 is a quick clamp, which is installed on the frame 221. The door body 223 can be quickly clamped and released through simple handle operation. The operation is convenient and quick, thereby reducing the requirements on the operator's skill level, reducing errors and delays caused by complex operations, and greatly improving work efficiency. At the same time, the quick clamp can provide stable and precise clamping force to ensure that the door body 223 will not be deformed during the locking process, thereby ensuring the stability of the door body 223.
