Description

Technical Field

[0001] The present invention relates to the technical field of pallets, and in particular to a pallet for replacing a jig. Background Art

[0002] Traditional automation is often achieved through the use of jigs, and generally requires multiple sets of jigs. Compared with the cost of a set of jigs, which can easily exceed thousands of yuan, there is an urgent need to explore alternatives to save costs. Pallets are a good alternative, but traditional pallets still have some defects and cannot meet the requirements of alternative jigs:

[0003] 1. In the traditional blister tray design, the products are arranged in the same direction. However, due to the limitation that the trays need to be rotated 180° before being stacked, the products will also have 180° differences, making it difficult to implement automated programs. In addition, traditional trays are mostly single or multiple integrated structures. A single tray cannot be used as a jig. Once the integrated tray is damaged, the entire tray cannot be used, which will increase the cost of using the tray.

[0004] 2. Existing pallets only support products. However, during automated operations, the pallets will move and rotate. The displacement of the pallets will cause the products inside the pallets to shake, thereby changing the product placement, which will affect the subsequent product grabbing process.

[0005] Therefore, there is an urgent need for a pallet that can be used to replace the jig. Summary of the Invention

[0020] (2) Beneficial effects

[0021] The present invention provides a tray for replacing a jig, which has the following beneficial effects:

[0022] 1. The present invention provides an anti-collision assembly and a base, wherein the elastic corner pad is made of an elastic material. At the same time, by adjusting the position of the locking tube on the fixed tube, the size of the clamping force of the flower head on the elastic rope can be adjusted, thereby completing the locking or loosening of the elastic rope, so that the length of the elastic rope on the adjacent side of the two sets of positioning blocks can be adjusted, so that a single group of pallets or multiple groups of pallets can be protected by the anti-collision assembly at the four corners, effectively preventing the four corners of the pallets from being damaged by impact and violent shaking, thereby affecting the stability of the products placed in the pallets, and at least two groups of pallets can be arranged and connected by the base, and the combined connecting blocks of the base on one group of pallets are connected to the connecting grooves of the base on the other group of pallets. Internally, at least two groups of pallets can be pre-connected. After the pre-connection of at least two groups of pallets is completed, the limit ring is allowed to enter the limit groove by rotating the threaded column to complete the locking of the connection between the several groups of pallets. When multiple groups of pallets are connected to each other, all of the bases below the common contact angle of the four groups of pallets are rotated 90° clockwise or counterclockwise and then connected in sequence. After several groups of pallets are connected, the stability of the assembly formed by connecting several groups of pallets using a set of anti-collision components is further enhanced by adjusting the length of the elastic rope in the anti-collision component. Through the assembly, a single pallet can be directly replaced after being damaged, further reducing the cost of using pallet replacement fixtures.

[0023] 2. The present invention provides a stabilizing portion. When a product is placed in the supporting groove, it will be supported by the supporting portion and the stabilizing portion. When the product is on the stabilizing portion, it will squeeze the supporting skirt. The hollow supporting skirt will deform, causing the gas inside the stabilizing portion to be discharged through the one-way valve. The stabilizing portion will have a suction force on the product, so that the product will not shake on the pallet when the pallet is moved. At the same time, the suction force of the stabilizing portion alone will not be too large, so that the removal of the product will not be affected. BRIEF DESCRIPTION OF THE DRAWINGS

The positioning blocks 22 are provided with mounting grooves 24 on both sides facing away from the elastic corner pads 21. Locking portions 25 are fixedly connected to the interior of the mounting grooves 24.

[0043] The locking portion 25 includes a fixing tube 251 and a locking tube 252 . The locking tube 252 is fixedly connected to the outside of the fixing tube 251 . One end of the fixing tube 251 is fixedly connected to a flower head 253 .

[0044] Furthermore, the elastic tube 142 is funnel-shaped, and the one-way valve 143 is installed at the end of the elastic tube 142 with a smaller outer diameter.

[0045] Specifically, when the product is placed in the supporting groove 12, it will be supported by the supporting portion 13 and the stabilizing portion 14. When the product is on the stabilizing portion 14, it will squeeze the supporting skirt 141, and the hollow supporting skirt 141 will be deformed, so that the gas inside the stabilizing portion 14 will be discharged through the one-way valve 143. The stabilizing portion 14 will have a suction force on the product, so that the product will not shake on the pallet when the pallet is moved. At the same time, the suction force of the stabilizing portion 14 alone will not be too large, so that the removal of the product will not be affected.

[0047] Specifically, a single group of pallets 1 or several groups of pallets 1 can protect the four corners through the anti-collision component 2, effectively preventing the four corners of the pallets from being damaged by impact and violent shaking, which would affect the stability of the product placement in the pallets.

[0048] It should be noted that the elastic corner pad 21 is made of elastic material.

[0049] See also Figure 4-7 The interior of the positioning block 22 is hollow, and parts of both ends of the elastic rope 23 are respectively received in the interior of the two groups of positioning blocks 22 .

[0050] Furthermore, the fixing tube 251 is connected to the locking tube 252 by threads, and the locking tube 252 is used to squeeze the outside of the flowering head 253 so that the inner diameter of the flowering head 253 away from the fixing tube 251 is reduced.

[0051] Specifically, by adjusting the position of the locking tube 252 on the fixing tube 251, the clamping force of the opening head 253 on the elastic rope 23 can be adjusted, thereby completing the locking or loosening of the elastic rope 23, so that the length of the elastic rope 23 on the adjacent side of the two sets of positioning blocks 22 can be adjusted.

[0052] Please participate Figure 2 、 8 and 9. The base 15 includes a base body 151 and a rotating connecting column 152.

[0054] Specifically, the friction force of the rubber ring 153 can effectively increase the difficulty of the base 15 rotating, thereby preventing the base 15 from rotating easily under the tray body 11 .

[0055] Furthermore, a limiting groove 1541 is provided on the upper end surface of the combined connecting block 154 , and a positioning groove 1542 is provided on the side end surface of the combined connecting block 154 . The positioning groove 1542 is connected to the bottom of the limiting groove 1541 , and the positioning groove 1542 is trumpet-shaped.

[0056] Specifically, at least two groups of pallets 1 can be arranged and connected through the base 15, and the combined connecting blocks 154 of the base 15 on one group of pallets 1 are connected to the connecting grooves 155 of the base 15 on another group of pallets 1, so that pre-connection can be completed between at least two groups of pallets 1.
