[0048] Specifically, in order to improve the work efficiency, two groups of material distribution devices 1 are arranged to uniformly distribute the metal rings 6 and the rubber blocks 7.

[0050] In the embodiment, in order to facilitate the receiving of the metal rings 6 or the rubber blocks 7 conveyed by the material conveying assembly 13 in turn, each material distribution groove 1431 can be moved above the end of the conveying belt 131, and in order to ensure the reliability of the system, as shown in the drawings, the distance adjusting assembly 1313 comprises a first adjusting member installed on one side of the conveying belt 131 at the corresponding position, and a second adjusting member installed on the blocking strip 132, a long slot hole is formed on the second adjusting member, and a sliding column is installed on the first adjusting member to slide in the long slot hole to adjust the distance between the two blocking strips 132. Figure 4As shown in the figure, a distance measuring sensor 1311 is installed at the end of the conveying belt 131, and the distance between the distance measuring sensor 1311 and the conveying belt 131 is set as a reference value. When the cloth is completed, the distance measuring sensor 1311 measures a value less than the reference value, so that whether the cloth in the cloth groove 1431 is completed is detected through the distance measuring sensor 1311, so as to ensure the reliability of the cloth.

[0051] As shown in the figure, a distance measuring sensor 1311 is installed at the end of the conveying belt 131, and the distance between the distance measuring sensor 1311 and the conveying belt 131 is set as a reference value. When the cloth is completed, the distance measuring sensor 1311 measures a value less than the reference value, so that whether the cloth in the cloth groove 1431 is completed is detected through the distance measuring sensor 1311, so as to ensure the reliability of the cloth. Figure 3 As shown in the figure, a distance measuring sensor 1311 is installed at the end of the conveying belt 131, and the distance between the distance measuring sensor 1311 and the conveying belt 131 is set as a reference value. When the cloth is completed, the distance measuring sensor 1311 measures a value less than the reference value, so that whether the cloth in the cloth groove 1431 is completed is detected through the distance measuring sensor 1311, so as to ensure the reliability of the cloth.

[0052] As shown in the figure, a distance measuring sensor 1311 is installed at the end of the conveying belt 131, and the distance between the distance measuring sensor 1311 and the conveying belt 131 is set as a reference value. When the cloth is completed, the distance measuring sensor 1311 measures a value less than the reference value, so that whether the cloth in the cloth groove 1431 is completed is detected through the distance measuring sensor 1311, so as to ensure the reliability of the cloth. Figure 2 As shown in the figure, a distance measuring sensor 1311 is installed at the end of the conveying belt 131, and the distance between the distance measuring sensor 1311 and the conveying belt 131 is set as a reference value. When the cloth is completed, the distance measuring sensor 1311 measures a value less than the reference value, so that whether the cloth in the cloth groove 1431 is completed is detected through the distance measuring sensor 1311, so as to ensure the reliability of the cloth. As shown in the figure, a distance measuring sensor 1311 is installed at the end of the conveying belt 131, and the distance between the distance measuring sensor 1311 and the conveying belt 131 is set as a reference value. When the cloth is completed, the distance measuring sensor 1311 measures a value less than the reference value, so that whether the cloth in the cloth groove 1431 is completed is detected through the distance measuring sensor 1311, so as to ensure the reliability of the cloth.

[0053] In order to better receive the metal rings 6 or rubber blocks 7 orderly transported by the feeding assembly 13, and at the same time, efficiently and accurately complete the uniform distribution of the metal rings 6 or rubber blocks 7, i.e. the distribution of the metal ring row and the rubber block row, the distribution assembly 14 is provided vertically to the feeding assembly 13. Figure 2 As shown in Figure 4 The distribution assembly 14 is vertically provided to the feeding assembly 13, and the distribution assembly 14 includes a fixed plate 142 supported on the base 11 via a support 141, and a displacement plate 143 provided above the fixed plate 142 and adjacent to the fixed plate 142, and a first X-axis linear module 145 provided on the base 11, the displacement plate 143 is connected with the first X-axis linear module 145 and is driven to displace, a plurality of distribution grooves 1431 are provided on the displacement plate 143 and spaced apart from each other on the side adjacent to the feeding assembly 13, the distribution assembly 14 further includes a baffle 144 mounted on the fixed plate 142 and adjacent to the distribution grooves 1431, the length of the baffle 144 is less than the length of the displacement plate 143, the fixed plate 142 is used for supporting the metal rings 6 or rubber blocks 7, the number of the distribution grooves 1431 provided on the displacement plate 143 corresponds to the number of the mold rows on the vulcanizing device 4, the uniform distribution of the metal rings 6 or rubber blocks 7 is realized through the distribution grooves 1431 on the displacement plate 143, in the process, the precise and reliable receiving of the material is realized in cooperation with the distance measuring sensor 1311, and the baffle 144 is provided to form resistance to the metal rings 6 or rubber blocks 7 received into the distribution grooves 1431 so as to keep the metal rings 6 or rubber blocks 7 in the grooves, and the length of the baffle 144 is less than the length of the displacement plate 143, which can just avoid the position of one distribution groove 1431, in the embodiment, the number of the distribution grooves 1431 is five.

[0054] The metal ring row (i.e. a row of metal rings 6) and the rubber block row (i.e. a row of rubber blocks 7) well distributed through the distribution device 1 are grabbed and stacked through the grabbing and stacking device 2, specifically, Figure 5 As shown in Figure 7 The grabbing and stacking device 2 includes a displacement assembly 21 arranged above the distribution device 1, and a metal ring grabbing and stacking assembly 22 and a rubber block grabbing and stacking assembly 23 respectively arranged on the displacement assembly 21, and further includes a stacking disc 24, specifically, the displacement assembly 21 includes two second X-axis linear modules 211 arranged above the distribution device 1, and a Y-axis linear module 212 arranged between the two second X-axis linear modules 211; further includes a Z-axis linear module 213 arranged on the Y-axis linear module 212, in order to make the structure compact and the displacement as small as possible, the metal ring grabbing and stacking assembly 22 and the rubber block grabbing and stacking assembly 23 are mounted on the Z-axis linear module 213 via a grabbing plate 214. Figure 5 As shown in Figure 6As shown, the metal ring gripping assembly 22 includes multiple finger cylinders 221 arranged at intervals, and two opposing grippers 222 respectively mounted on each finger cylinder 221. The inner surface of each gripper 222 is V-shaped. Specifically, there are five finger cylinders 221. The V-shaped inner surface of each gripper 222 can reliably grip the metal ring 6 with a cylindrical outer surface, thus preventing the metal ring 6 from slipping off the gripper 222.

[0055] Because of the unique cross-shaped twisted pattern of rubber block 7, it cannot be gripped using the clamping method 222. Figure 7 Combination Figure 8 As shown, the rubber block gripping and clamping assembly 23 includes a gripping pressure plate 231 and a plurality of clamping assemblies 232 spaced apart on the connecting block 233. It also includes a reciprocating cylinder mounted on the gripping plate 214 to drive the connecting block 233 to reciprocate. A plurality of through holes 2311 are spaced apart on the gripping pressure plate 231 for the corresponding clamping assemblies 232 to pass through. The diameter of the through holes 2311 is smaller than the outer diameter of the rubber block 7. Specifically, each clamping assembly 232 includes a clamping connector and a clamping needle detachably connected to the clamping connector. Specifically, there are five clamping assemblies 232.

[0056] The reciprocating cylinder actuates, causing multiple clamping components 232, which are spaced apart on the connecting block 233, to move downwards simultaneously. The spacing between the clamping components 232 is adapted to the spacing of the fabric groove 1431, thereby clamping the rubber block 7 at the corresponding position to achieve reliable gripping of the rubber block 7. Conversely, the reciprocating cylinder actuates, causing multiple clamping components 232, which are spaced apart on the connecting block 233, to move upwards simultaneously. Due to the blocking effect of the material-taking pressure plate 231, which has multiple through holes 2311 for the corresponding clamping components 232 to pass through, and because the diameter of the through holes 2311 is smaller than the outer diameter of the rubber block 7, the rubber block 7 is dislodged from the clamping components 232, thus placing the rubber block on the metal ring.

[0057] To improve efficiency, each set of material feeding devices 1 has two sets of material feeding components 14. Each set of material feeding components 14 in the same material feeding device 1 is symmetrically arranged relative to its corresponding material conveying component 13, so that the two sets of symmetrical material feeding components 14 feed the material in an alternating manner, which facilitates the alternating gripping of the material grabbing device 2. The material grabbing device 2 then grabs and stacks the material in an alternating manner, and finally forms four rows of five skeleton oil seals in each row on the stacking plate 24 before vulcanization molding.

[0058] To facilitate the loading of the aforementioned material stacked on the stacking tray 24 into the vulcanizing device 4, by Figure 1 Combination Figure 10As shown in the figure, the taking and placing device 3 comprises a mechanical hand 31, a grabbing chassis 33 connected to the mechanical hand 31 via a connecting flange 32, and a plurality of taking and placing assemblies 34 arranged on the grabbing chassis 33. Specifically, the arrangement of the taking and placing assemblies 34 is the same as that of the skeleton oil seal on the stacking tray 24, and the structure of the taking and placing assemblies 34 is the same as that of the metal ring grabbing and stacking assembly 22, which will not be described herein again. In the embodiment, the model of the mechanical hand 31 is CRP-RA27-50, and a control box with a PLC controller is also provided in the embodiment. Specifically, the mechanical hand 31, the vibrating disc 12, the conveying belt 131, the distance sensor 1311, the pair of sensors 1312, the grabbing and stacking device 2, etc. are in signal communication with the PLC controller, and can be selected and programmed for control, which will not be described herein again. In the embodiment, the vulcanizing device 4 can be selected from the prior art, which will not be described herein again. The PLC controller is in signal communication with the mechanical hand 31 to adjust the angle of the taking and placing assembly 34. The skeleton oil seal array vulcanized by the vulcanizing device 4 is removed by the taking and placing assembly 34. In order to detect the integrity of the removed skeleton oil seal on the vulcanizing device 4, the detection device 5 comprises a base frame 51 and a belt scale 52 mounted on the base frame 51, and a display screen 53. The belt scale 52 weighs the skeleton oil seal removed from the vulcanizing device 4 by the taking and placing device 3 to detect the integrity of the removed skeleton oil seal, and the display screen 53 is in signal communication with the PLC controller. At the same time, the detection device 5 also comprises a holding tray 54 for holding the detected skeleton oil seal.
