Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and embodiments.

Example 1

The present embodiment discloses a split mold assembly tool, which includes an assembly table 1 for placing an upper mold 2 and a lower mold 3 respectively. In this embodiment, as shown in FIG. 1 , the upper mold 2 is provided with protrusions on the surface, so the upper mold 2 and the lower mold 3 are stacked separately. It also includes: a material table 4, which is set to place positioning pieces. The positioning member is used to realize the positioning connection between the upper mold 2 and the lower mold 3 .

In this embodiment, the upper mold is selected to be fastened to the lower mold or the lower mold is selected to be fastened to the upper mold according to the requirements, and the working principle is the same. Take the selection of the lower mold to be fastened on the mold as an example: between the assembly table 1 and the material table 4, there are assembly jaws, and the assembly jaws are set to grip, transfer, and place positioning parts to complete the upper and lower molds. Assembly between 3. One side of the assembly table 1 is provided with a conveyance jaw, which is arranged to fasten the lower die 3 on the upper die 2 . After the upper mold 2 and the lower mold 3 are assembled, they are transferred to the tray of the transmission belt by the conveying jaws, and the next process detection is carried out.

In a further embodiment, in order to quickly complete the assembly between the upper and lower molds 3 , the positioning member includes: an upper bushing 5 , a positioning pin 6 and a lower bushing. The upper bushing 5 has the same structure as the lower bushing, and both are cylindrical shells with an open structure at one end. When in use, firstly insert the upper bushing 5 on each assembly hole of the upper die 2 with the open structure facing upwards, and then insert the positioning pin 6 into the upper bushing 5. After the positioning pin 6 is installed, the The assembling holes of the lower mold 3 are aligned with the positioning pins 6 and fastened to the upper mold 2; then, each positioning pin 6 is covered with the upper and lower bushings, that is, the open structure of the lower bushing faces downwards. In other words, the lower bush is fitted on the fitting hole of the lower die 3 .

Because the positioning member is a columnar structure and is composed of two bushings and the positioning pin 6, that is, the outer diameters of the bushing and the positioning pin 6 are different, so in order to enable the assembly jaws to grasp the bushing and the positioning pin 6 at the same time Therefore, in this embodiment, the assembling jaws include: an assembling mechanical arm 7, the end of which is provided with a Z-axis moving component. The assembling robot arm 7 and the Z-axis moving component are used to realize the movement in the three-axis direction, which can be realized by using the existing technology, so it is not repeated here.

A first clamping jaw cylinder 8 is driven and connected to the Z-axis moving assembly. The driving end of the first clamping jaw cylinder 8 is symmetrically provided with two sets of clamping plates 9 , that is, the first clamping jaw cylinder 8 is used to drive the two sets of clamping plates 9 Move toward or away from each other to form an elastic clamping space for clamping bushings and positioning pins 6 with different outer diameters. And because the bushing and the positioning pin 6 are cylinders, in order to prevent slippage, two sets of clamping blocks 10 are mirrored at the end of the inner wall of the clamping plate 9, and a predetermined gap is left between the two clamping blocks 10. The opposite surfaces of the two clamping blocks 10 are inclined surfaces, which are convenient for clamping the cylinder.

Similarly, in order to be suitable for the clamping of the upper mold 2 and the lower mold 3, in this embodiment, the conveying jaws include: an assembling mechanical arm 7, which is used to realize the movement in the three-axis direction, all using the prior art It can be realized, so it is not repeated here.

The second clamping jaw cylinder 11 is arranged at the end of the assembly mechanical arm 7, and two sets of clamping arms 12 are provided at the driving end of the second clamping jaw cylinder 11. Under the action of the claw cylinder 11 , move toward or away from each other to realize the clamping and loosening of the upper and lower molds 3 .

Based on the above description, the positioning member is composed of two sets of bushings (upper bushing 5, lower bushing) and positioning pins 6, so when placing, the bushings and positioning pins 6 are placed in a classified manner, and since the bushing and The positioning pins 6 are all cylinders, so in order to ensure the stability during placement and the convenience during clamping with the assembling jaws. Therefore, in this embodiment, the bushings (the upper bushing 5 and the lower bushing) and the positioning pins 6 are placed vertically. Therefore, the material table 4 is provided with a material rack, including: a plurality of support legs 13 fixed on the material table 4, and a support surface 14 connected to the support legs 13, wherein the upper surface of the support surface 14 is from above And the lower recess has a predetermined depth to form a plurality of placement grooves, and the placement grooves are configured to accommodate the positioning members. Easy to manage and easy to grip.

In a further embodiment, in order to ensure that each assembly hole in the upper mold 2 is provided with a corresponding positioning member, an optical fiber sensor is installed on the assembly jaws to detect the installation of the positioning member.

The working principle of this embodiment is as follows: read the values to determine the types of the upper mold 2 and the lower mold 3, replace the corresponding assembly jaws and transport jaws, and use the transport jaws to classify the upper mold 2 and lower mold 3 on the tray and place them On the assembly table 1, the assembly jaws assemble the bushings and the positioning pins 6 according to the prescribed logic: sequentially clamp n bushings and insert them into the assembly holes of the upper mold 2, and then sequentially assemble the positioning pins 6 for each bushing. , and then grab n bushings on the top of the positioning pins 6 in turn. After the positioning parts are assembled, the lower mold 3 is fastened on the upper mold 2 using the handling jaws, and the positioning parts located in the upper mold 3 and the lower mold The assembly holes of the mold 3 are opposite to each other, and the optical fiber sensor is used for detection during placement. Among them, it is an integer, which is consistent with the number of assembly holes. In this embodiment, n=4. Finally, the assembled upper and lower molds 3 are placed on the tray of the conveyor belt using the handling jaws, and flow to the next inspection station.
