Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding field especially relates to a single group detection signal confirms full -automatic mechanical hand fixture of many groups of clamping product. BACKGROUND

[0002] At present, injection molding products are usually taken out by using suction cup adsorption or water hole clamping, but some products cannot be taken out by using the above-mentioned methods due to the product structure and the number of cavities in the mold. For example, the product cannot be taken out by using the clamping signal because the product has no suction surface on the front side. In order to prevent the mold from being pressed, workers usually take out the products manually. However, the manual operation increases the labor intensity of the workers and the production cycle is unstable, which has a great influence on the yield of the products. In order to improve the production efficiency and the production quality and reduce the labor intensity of the workers, an automatic device is needed to take out the products. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model provides a full -automatic mechanical hand fixture of single signal confirmation many groups of clamping product, after the mold ejects product, through to the mechanical hand programming, array pneumatic parallel clamps respectively clamping specified product, through increasing photoelectric switch and relay block contact point closure forms the passage output signal confirmation to take out the product, to complete the product taking out process.

[0004] The technical scheme of the utility model is as follows: a full -automatic mechanical hand fixture of single group detection signal confirmation many groups of clamping product, including base, pneumatic parallel clamps, photoelectric switch, the pneumatic parallel clamps are arranged on the base, the photoelectric switch is arranged in the clamping groove of pneumatic parallel clamps, and the gas inlet on the pneumatic parallel clamps is connected with the gas inlet of the mechanical hand.

[0005] According to the number and arrangement of the cavities of the mold, there are eight groups of pneumatic parallel clamps and photoelectric switches, which are divided into two rows, and each row has four groups. There are two sets of relay blocks, and the model of the relay block is G6B-4BND DC24V four-way normally open 5A. Each set of relay block is connected with four groups of pneumatic parallel clamps and photoelectric switches in one row.

[0006] The utility model has the advantages that the installation of the relay block and the multiple photoelectric switches can cooperate with the mechanical hand to automatically complete the work of confirming and taking out the products, thereby improving the efficiency and the qualification rate.

[0012] like Figs. 1 to 4 As shown, a fully automatic robotic jig for picking up multiple products by confirming a single set of detection signals includes a base 1, a pneumatic parallel clamp 2, and a photoelectric switch 4.

[0013] Photoelectric switches 4 are inserted into the slots of each pneumatic parallel clamp 2. Based on the number and arrangement of the mold cavities, there are eight sets of pneumatic parallel clamp 2 and photoelectric switch 4 assemblies, arranged in two rows of four, fixed to the base 1 with bolts 6. Above each row of pneumatic parallel clamp 2 and photoelectric switch 4 assemblies, a relay block 3 (model G6B-4BND DC24V, four-way normally open 5A) is fixed to the base 1 with bolts 6. Each relay block 3 controls one row of four pneumatic parallel clamp 2 and photoelectric switch 4 assemblies. The positive terminals +5, +6, +7, and +8 of the two relay blocks are connected in parallel with the orange positive terminals of the eight photoelectric switches, and then connected to the robotic arm. The three negative terminals -1, -2, -3, and -4 of the two relay blocks are individually connected to the corresponding blue negative terminals of the photoelectric switches. The eight normally open auxiliary contacts of the two sets of relay blocks 3 are connected in series. The first end is connected to the robot arm, and the second end is connected in parallel to multiple sets of black output wires of eight photoelectric switches 4. After the connection, a blue wire is connected to the robot arm. In use, the base 1 is fixed on the robot arm, and the air inlets 2-2 of the eight sets of pneumatic parallel clamps 2 are connected in parallel to the air circuit of the robot arm. When taking out a product, the clamping plates 2-1 of the eight sets of pneumatic parallel clamps 2 are programmed to grab the designated product 5. The eight sets of photoelectric switches 4 confirm the product 6, control the coils to close, and make the eight sets of normally open contacts close. The eight signal sources form a path to the robot arm. After the robot arm confirms the signal, it takes out the product according to the program and places it on the conveyor belt to complete the whole process.

[0014] Using this invention can reduce the labor intensity of workers, reduce product defects, and achieve fully automated production.
