[0029] Please refer to Figure 1 , Figure 1is a structural schematic diagram of an embodiment of an automatic positioning and crimping system of the present application. The automatic positioning and crimping system comprises a crimping machine 110, a first positioning device 120, a second positioning device 130 and a third positioning device 140. The crimping machine 110 is used to crimp a product located at a first preset crimping position or a second preset crimping position. The first positioning device 120 is located at one side of the crimping machine 110 and is used to place a product to be sleeved and move the product to be sleeved to the first preset crimping position. The second positioning device 130 is located at the other side of the crimping machine 110 and is used to place an intermediate sleeve and move the intermediate sleeve to the first preset crimping position to sleeve the intermediate sleeve to the product to be sleeved and move the sleeved product to be sleeved to the second preset crimping position. The third positioning device 140 is arranged at one side of the crimping machine 110 and at one side of the first positioning device 120 and is used to place an end sleeve and move the end sleeve to the second preset crimping position to sleeve the end sleeve to the product to be sleeved. The first positioning device 120, the second positioning device 130 and the third positioning device 140 can be arranged to move to the preset crimping position in a first preset direction.

[0030] The automatic positioning and crimping system of the present application is mainly used for producing cross arm products. The automatic positioning and crimping system can sleeve and crimp the product to be sleeved and the sleeve to assemble the cross arm product. The product to be sleeved can be a core rod, etc. The sleeve can be a fitting, etc. The intermediate sleeve is sleeved at the middle position of the product to be sleeved and the end sleeve is sleeved at the end of the product to be sleeved.

[0031] In some embodiments, in the automatic positioning and crimping system, after the product to be sleeved is placed on the first positioning device 120, the intermediate sleeve is placed on the second positioning device 130 and the end sleeve is placed on the third positioning device 140, the intermediate sleeve can be moved to the first preset crimping position by the second positioning device 130 in the first preset direction and the product to be sleeved can be moved to the first preset crimping position by the first positioning device 120 in the first preset direction. In the first preset crimping position, the intermediate sleeve is sleeved at the middle position of the product to be sleeved and then the intermediate sleeve is crimped on the product to be sleeved by the crimping machine 110. In addition, the first positioning device 120 can be moved to the first preset crimping position in the first preset direction first and then the second positioning device 130 can be moved to the first preset crimping position in the first preset direction to sleeve the intermediate sleeve at the middle position of the product to be sleeved. Therefore, the moving sequence of the first positioning device 120 and the second positioning device 130 in the process of sleeving the intermediate sleeve at the middle position of the product to be sleeved is not specifically limited herein.

[0032] Afterwards, the product to be sleeved with the intermediate sleeve device can be carried by the second positioning device 130, and the end sleeve device is moved to the second preset crimping position along the first preset direction by the third positioning device 140, so as to sleeve the end sleeve device on one end of the product to be sleeved, and then the end sleeve device is crimped on the product to be sleeved by the crimping machine 110. In the automatic positioning and crimping system, the crimping machine 110 is fixed and cannot be moved, so the first preset crimping position and the second preset crimping position can be arranged in the crimping machine 110, and after the product is sleeved at the first preset crimping position and the second preset crimping position, the product can be immediately crimped, thereby improving the crimping efficiency. Similarly, in the process of sleeving the end sleeve device on the end of the product to be sleeved, the moving sequence of the second positioning device 130 and the third positioning device 140 is not specifically limited here.

[0033] In some embodiments, since the first positioning device 120 and the third positioning device 140 are located on the same side of the crimping machine 110, and the first positioning device 120 and the third positioning device 140 need to move towards the crimping machine 110, in order to orderly control the movement of the first positioning device 120 and the third positioning device 140, a driving assembly can be arranged at the bottom of the first positioning device 120 and the third positioning device 140 respectively, so that the first positioning device 120 and the third positioning device 140 can move independently and orderly, and no interference or collision occurs.

[0034] In some embodiments, in order to further measure whether the position of the sleeve device sleeved or crimped on the product to be sleeved is correct, a detection device can be arranged on the crimping machine 110. The detection device can at least include a camera detection assembly, which can obtain a sleeving image or a crimping image of the sleeve device, and compare the obtained image with a preset image in the automatic positioning and crimping system, so as to determine whether the position of the sleeve device sleeved or crimped on the product to be sleeved is correct. In addition, the detection device can also include a laser positioning assembly, which is not specifically limited here.

[0035] Please refer to Figure 2 , Figure 2FIG. 1 is a structural schematic diagram of an embodiment of a first positioning device 120 according to the present application. The first positioning device 120 comprises a first base plate 121, a first guide rail 122, a first mounting plate 123, a displacement assembly 124, a first power assembly 125, and a first transmission assembly 126. The first guide rail 122 is arranged on the first base plate 121. The first mounting plate 123 is connected to the first guide rail 122 through a first sliding block. The displacement assembly 124 is arranged on the first mounting plate 123. The displacement assembly 124 is used to support a product to be sleeved and control the movement of the product to be sleeved. The first power assembly 125 is arranged at one end of the first guide rail 122. The first transmission assembly 126 is connected to the first power assembly 125. The first transmission assembly 126 is used to transmit the power output by the first power assembly 125 to the first mounting plate 123, so as to drive the first mounting plate 123 to move on the first guide rail 122. It can be understood that the first power assembly 125 can be a power source such as a motor or a pneumatic cylinder, and the first transmission assembly 126 can be a screw transmission structure or a gear transmission structure, which is not specifically limited here.

[0036] In some embodiments, the displacement assembly 124 comprises a first support 1241, a second support 1242, and a push plate 1243. The first support 1241 and the second support 1242 are arranged on the first mounting plate 123 in a spaced manner. The push plate 1243 is arranged on a side of the second support 1242 away from the first support 1241. The push plate 1243 is used to abut and push the product to be sleeved placed on the first support 1241 and the second support 1242 to move.

[0037] In some specific application scenarios, after the product to be sleeved is placed on the first support 1241 and the second support 1242 and the push plate 1243 abuts the product to be sleeved, the first mounting plate 123 is driven to move along a first preset direction by the first power assembly 125, thereby driving the push plate to push the product to be sleeved to move.

[0038] In some embodiments, in order to further improve the quality of the product splicing, at the same time, increase the maximum moving distance of the first positioning device 120 to the product to be spliced, and make the automatic positioning and pressing system more widely applicable, the push plate 1243 is set as a movable mechanism. Specifically, the displacement assembly 124 includes a first support 1241, a second support 1242, a push plate 1243, and a second power assembly (not shown in the figure). The first support 1241 and the second support 1242 are arranged on the first mounting plate 123 in a spaced manner, and the push plate 1243 is arranged on the side of the second support 1242 away from the first support 1241. The push plate 1243 is connected with the second power assembly, and the second power assembly is used to drive the push plate 1243 to move along the direction of the first support 1241, so as to further push the product to be spliced placed on the first support 1241 and the second support 1242 to move. It can be understood that the second power assembly can be a power source such as a motor or a pneumatic cylinder, which is not specifically limited here. Among them, considering that there may be some smaller convex points on the inner wall of the intermediate sleeve, which will cause abnormal resistance when the intermediate sleeve is sleeved on the mandrel, hindering the splicing of the intermediate sleeve and the mandrel. Therefore, the second power assembly can include a servo motor and a speed reducer. When there is abnormal resistance when the mandrel passes through the intermediate sleeve, the speed reducer is used to reduce the moving speed of the mandrel, and at the same time, the servo motor is controlled to slowly increase the power output, so as to overcome the abnormal resistance when the mandrel passes through the intermediate sleeve, and ensure the accuracy of the splicing position.

[0039] In some specific application scenarios, the product to be spliced is placed on the first support 1241 and the second support 1242. The intermediate sleeve can be moved to the first preset pressing position along the first preset direction through the second positioning device 130. The product to be spliced is driven by the first power assembly 125 of the first positioning device 120 to move along the first preset direction to the vicinity of the first preset pressing position, and then the push plate 1243 is precisely driven by the second power assembly to push the product to be spliced to move along the first preset direction to the first preset pressing position for splicing, so that the splicing position is more accurate.

[0040] In some other embodiments, the displacement assembly 124 comprises a first support 1241, a second support 1242 and a push plate 1243, the first support 1241 and the second support 1242 are arranged on the first mounting plate 123 at intervals, the first mounting plate 123 has a hollow groove on the side away from the first support 1241, the push plate 1243 is arranged in the hollow groove, and the push plate 1243 is connected with the first transmission assembly 126. After the first power assembly 125 moves the first mounting plate 123 to the farthest end of the first guide rail 122, the first mounting plate 123 cannot continue to move, but the first power assembly 125 can continue to output power, at this time the first transmission assembly 126 transmits power to the push plate 1243, so that the push plate 1243 pushes the product to be sleeved which abuts against it in the first preset direction, thereby increasing the maximum moving distance of the product to be sleeved by the first positioning device 120, and making the application range of the automatic positioning and pressing system wider.

[0041] Specifically, the first support 1241 and the second support 1242 can be roller devices, which can be used to cooperate with the push plate 1243 to realize the movement of the product to be sleeved and reduce the friction force. In addition, the first support 1241 and the second support 1242 can also be provided with lifting devices for adjusting the height of the roller devices.

[0042] Further, when the length of the product to be sleeved is relatively long, in order to better support the product to be sleeved, the first positioning device 120 further comprises a fixed support 127, which is fixedly arranged on the first bottom plate 121 close to one end of the pressing machine 110, and the fixed support 127 and the support points on the first support 1241 and the second support 1242 are located in the same vertical plane. The fixed support 127 is also a height-adjustable roller device, so that its height can be adjusted in accordance with the first support 1241 and the second support 1242, so that the fixed support 127 and the first support 1241 and the second support 1242 can cooperate with each other to stably support the product to be sleeved without affecting the driving of the product to be sleeved by the first power assembly 125 or the second power assembly. It can be understood that the above-mentioned fixed support 127 can also be provided with multiple fixed supports, or can also be movable, and the present application does not make specific limitation thereto.

[0043] Please refer to Figure 3 , Figure 3is a structural schematic view of an embodiment of the second positioning device 130 of the application. The second positioning device 130 comprises a second base plate 131, a second guide rail 132, a second mounting plate 133, a limiting assembly 134, a third power assembly 135, and a second transmission assembly 136. The second guide rail 132 is arranged on the second base plate 131. The second mounting plate 133 is connected with the second guide rail 132 through a second sliding block. The limiting assembly 134 is arranged on the second mounting plate 133 and is used for supporting the intermediate sleeve set and controlling the intermediate sleeve set to move to a preset position. The third power assembly 135 is arranged at one end of the second guide rail 132. The second transmission assembly 136 is connected with the third power assembly 135, and the second transmission assembly 136 is used for transmitting the power output by the third power assembly 135 to the second mounting plate 133, so as to drive the second mounting plate 133 to move on the second guide rail 132. It can be understood that the third power assembly 135 can be a power source such as a motor or a pneumatic cylinder, and the second transmission assembly 136 can be a screw transmission structure or a gear transmission structure, which is not specifically limited here.

[0044] In some embodiments, the limiting assembly 134 comprises a third support 1341, a baffle 1342, and a fourth power assembly 1343. The third support 1341 is arranged on the second mounting plate 133 and is used for placing the intermediate sleeve set. The baffle 1342 is arranged on one side of the third support 1341. The fourth power assembly 1343 is arranged on the other side of the third support 1341 and is used for driving the intermediate sleeve set to move along the direction of the baffle 1342 until the intermediate sleeve set abuts against the baffle 1342. Specifically, the fourth power assembly 1343 is a pneumatic cylinder, and the power output end of the pneumatic cylinder is connected with a push plate. After the intermediate sleeve set is placed on the third support 1341, the pneumatic cylinder controls the push plate to move in a second preset direction, so as to push the intermediate sleeve set to also move in the second preset direction until the intermediate sleeve set abuts against the baffle 1342 in the second preset direction. The pneumatic cylinder stops moving, so as to fix the intermediate sleeve set through the pneumatic cylinder and the baffle 1342. The second preset direction is the direction from the fourth power assembly 1343 to the baffle 1342, and the second preset direction intersects with the first preset direction. The included angle between the second preset direction and the first preset direction can be any angle. In this embodiment, the second preset direction is perpendicular to the first preset direction. It can be understood that the fourth power assembly 1343 can also be a power source such as a motor, which is not specifically limited here.

[0045] In some embodiments, to further limit the position of the intermediate sleeve, prevent the intermediate sleeve from moving during the sleeving or crimping, the abutting assembly 137 is further provided in the second positioning device 130. The abutting assembly 137 is provided on the second mounting plate 133, and is used to abut the end of the intermediate sleeve away from the crimping machine 110. In order to avoid the abutting position of the abutting assembly 137 being too high to affect the sleeving process of the product to be sleeved, the abutting assembly only abuts the bottom plate of the end of the intermediate sleeve used for sleeving the product to be sleeved. Specifically, the abutting assembly 137 includes a base, an abutting rod and a cylinder, the base is fixed on the second mounting plate 133, the abutting rod and the cylinder are provided on the base, the cylinder is used to drive the abutting rod to move in a first preset direction, so as to push the intermediate sleeve to also move in the first preset direction, until the intermediate sleeve abuts against the baffle 1342 in the first preset direction, and the cylinder stops moving, so that the intermediate sleeve is further fixed by the cylinder and the abutting rod, and during the sleeving and crimping process, the abutting rod can continuously abut against the bottom plate of the intermediate sleeve, so that the intermediate sleeve is always in the preset crimping position, and the product quality is guaranteed. Further, the abutting rod can adjust the abutting angle, so that the abutting rod can abut against one end of the sleeve for different specifications of the sleeve.

[0046] In some embodiments, the first preset crimping position of different intermediate sleeves can be different, therefore, in order to expand the application range of the automatic positioning and crimping system, the second positioning device 130 further includes a first moving assembly 138, which is connected with the bottom of the second bottom plate 131, and is used to control the height of the intermediate sleeve. Specifically, the first moving assembly 138 includes a cylinder and four guide columns, the guide columns are connected with the four corners of the bottom of the second bottom plate 131, and the power output end of the cylinder is connected with the bottom of the second bottom plate 131, so as to control the lifting of the second bottom plate 131 by the cylinder, thereby controlling the height of the intermediate sleeve, so that the intermediate sleeve reaches the height of the first preset crimping position and the second preset crimping position.

[0047] Please refer to Figure 4 , Figure 4 is a structural schematic view of an embodiment of the third positioning device 140 of the present application. The third positioning device 140 includes a third bottom plate 141, a multi-stage telescopic assembly 142 and a base 143. The multi-stage telescopic assembly 142 is provided on the third bottom plate 141, and is used to control the end sleeve to move to the second preset crimping position. The base 143 is provided on the multi-stage telescopic assembly 142, and is used to fix the end sleeve. Further, the shape of the base 143 can match the contour of the end sleeve, or a magnetic attraction structure or a pressing mechanism can also be provided on the base 143, so as to further limit and fix the end sleeve, and avoid the end sleeve from falling and affecting the subsequent sleeving and crimping process.

[0048] In some embodiments, to avoid interference and collision between the first positioning device 120 and the third positioning device 140, while reducing the complexity of the automatic positioning crimping system, the third positioning device 140 and the first positioning device 120 can be located on the same base. A driving assembly is arranged at the bottom of the base, and the first positioning device 120 and the third positioning device 140 can be moved simultaneously by the driving assembly. Specifically, the driving assembly includes a sixth guide rail (not shown in the figure), a sixth power assembly (not shown in the figure), and a fourth transmission assembly (not shown in the figure). The sixth guide rail is connected to the base through a sixth sliding block. The sixth power assembly is arranged on one side of the sixth guide rail, and is used to drive the base to move on the sixth guide rail, so as to synchronously control the movement of the first positioning device 120 and the third positioning device 140. The fourth transmission assembly is connected to the sixth power assembly, and the fourth transmission assembly is used to transmit the power output by the sixth power assembly to the base.

[0049] In some embodiments, the multi-stage telescopic assembly 142 includes a first-stage telescopic assembly and a second-stage telescopic assembly. The first-stage telescopic assembly is arranged on the third bottom plate 141, and the second-stage telescopic assembly is arranged on the first-stage telescopic assembly. The first-stage telescopic assembly is used to control the movement of the second-stage telescopic assembly, and the second-stage telescopic assembly is used to control the movement of the base 143.

[0050] Specifically, the first-stage telescopic assembly includes a third guide rail 1421, a third mounting plate 1422, a fifth power assembly 1423, and a third transmission assembly 1424. The third guide rail 1421 is arranged on the third bottom plate 141, and the third mounting plate 1422 is connected to the third guide rail 1421 through a third sliding block. The fifth power assembly 1423 is arranged at one end of the third guide rail 1421, and is used to drive the third mounting plate 1422 to move on the third guide rail 1421. The third transmission assembly 1424 is connected to the fifth power assembly 1423, and the third transmission assembly 1424 is used to transmit the power output by the fifth power assembly 1423 to the third mounting plate 1422.

[0051] The base 143 includes a first base 1431 and a second base 1432, and the second-stage telescopic assembly includes a fourth guide rail 1425, a fifth guide rail 1426, a first air cylinder 1427, and a second air cylinder 1428. The first base 1431 is connected to the fourth guide rail 1425 through a fourth sliding block, and the second base 1432 is connected to the fifth guide rail 1426 through a fifth sliding block. The first air cylinder 1427 is connected to the first base 1431, and is used to control the first base 1431 to move along the fourth guide rail 1425. The second air cylinder 1428 is connected to the second base 1432, and is used to control the second base 1432 to move along the fifth guide rail 1426.

[0052] When the end sleeve is moved by the multi-stage telescopic assembly 142, the first base 1431 and the second base 1432 are first moved to a suitable position of the third guide rail 1421 along a first preset direction by the fifth power assembly 1423, then the first base 1431 is controlled to move along the first preset direction by the first air cylinder 1427 until the end sleeve on the first base 1431 moves to a second preset crimping position, or the second base 1432 is controlled to move along the first preset direction by the second air cylinder 1428 until the end sleeve on the second base 1432 moves to the second preset crimping position.

[0053] In a specific application scenario, when one of the end sleeves on the base 143 completes the sleeving and crimping process, the corresponding first base 1431 or second base 1432 is controlled to retreat, and then the third positioning device 140 is controlled to move along the sixth guide rail direction so that the other end sleeve on the base 143 is in a suitable position of the corresponding second base 1432 or first base 1431, and then the other end sleeve is controlled to move along the first preset direction to the second preset crimping position for sleeving and crimping.

[0054] In addition, the first air cylinder 1427 and the second air cylinder 1428 can also be connected to a speed reducer. When there is an abnormal resistance in the process of sleeving the end sleeve on the core rod, the speed of the end sleeve is first reduced by the speed reducer, and the power output of the first air cylinder 1427 or the second air cylinder 1428 is controlled to increase slowly to overcome the abnormal resistance when the end sleeve is sleeved on the core rod.

[0055] In some embodiments, the second preset crimping positions of different end sleeves can be different. Therefore, to expand the application range of the automatic positioning and crimping system, a second moving assembly 144 can be arranged in the third positioning device 140. The second moving assembly 144 is arranged at the bottom of the third bottom plate 141, and is used to control the movement of the third bottom plate 141, thereby controlling the height of the base 143 moving to the second preset crimping position. Specifically, the power source of the second moving assembly 144 can be an air cylinder, which is used to control the lifting of the base 143. The second moving assembly 144 has a similar structure to the first moving assembly 138, and will not be described here.

[0056] Please refer to Figure 5 , Figure 5 which is a flowchart of an embodiment of the automatic positioning and crimping control method of the present application. The specific steps are as follows:

[0057] Step 510: In response to the sleeving signal, the product to be sleeved and the intermediate sleeve are controlled to move to a first preset crimping position for sleeving.

[0058] In some embodiments, a detection assembly can be arranged on the first positioning device 120, the second positioning device 130 and the third positioning device 140, which can be used to detect whether the to-be-crimped product is placed on the first positioning device 120, whether the intermediate sleeve is placed on the second positioning device 130, and whether the end sleeve is placed on the third positioning device 140. When it is detected that the to-be-crimped product is placed on the first positioning device 120, the intermediate sleeve is placed on the second positioning device 130, and the end sleeve is placed on the third positioning device 140, the detection assembly generates a crimping signal and sends it to the automatic positioning crimping system. The automatic positioning crimping system controls the second positioning device 130 to move the intermediate sleeve to the first preset crimping position along the first preset direction, and then controls the first positioning device 120 to move the to-be-crimped product to the first preset crimping position along the first preset direction, so that the to-be-crimped product passes through the intermediate sleeve, and finally the intermediate sleeve is crimped at the intermediate position of the to-be-crimped product.

[0059] In other embodiments, the automatic positioning crimping system can be operated by an operator to generate a crimping signal. The automatic positioning crimping system starts the first positioning device 120 and the second positioning device 130 to crimp the to-be-crimped product and the intermediate sleeve according to the crimping signal.

[0060] Specifically, the to-be-crimped product is placed on the first support 1241 and the second support 1242, the intermediate sleeve is placed on the third support 1341, and the first power assembly 125 is used to move the to-be-crimped product along the first preset direction. When the intermediate sleeve and the to-be-crimped product are both moved to the first preset crimping position, the first power assembly 125 or the second power assembly continues to output power to start crimping, and the push plate 1243 is controlled to push the to-be-crimped product to move towards the intermediate sleeve until the intermediate sleeve is crimped at the intermediate position of the to-be-crimped product.

[0061] In some specific embodiments, based on the crimping signal, the control step 510 of the automatic positioning crimping system includes steps 511 to 513.

[0062] Step 511: In response to the crimping signal, the limiting assembly of the second positioning device is used to control the intermediate sleeve to move to a preset position, and the third power assembly of the second positioning device is used to move the intermediate sleeve at the preset position to the first preset crimping position.

[0063] In some embodiments, after the intermediate sleeve is placed on the third support 1341 of the limiting assembly 134, the fourth power assembly 1343 is used to push the intermediate sleeve to be fixed and limited, so that the intermediate sleeve abuts against the baffle 1342 along the second preset direction, and the abutting assembly 137 is used to abut against the end of the intermediate sleeve away from the crimping machine 110, so that the intermediate sleeve abuts against the baffle 1342 along the first preset direction. The first moving assembly 138 is controlled to lift the intermediate sleeve to the height of the first preset crimping position, and then the third power assembly 135 is used to move the intermediate sleeve to the first preset crimping position along the first preset direction.

[0064] Step 512: The first power assembly of the first positioning device is controlled to move the product to be sleeved to the first preset crimping position.

[0065] In some embodiments, after the intermediate sleeve is moved to the first preset crimping position, the automatic positioning crimping system controls the first power assembly 125 of the first positioning device 120 to transmit the output power to the first mounting plate 123 through the first transmission assembly 126, controls the first mounting plate 123 to move along the first preset direction, so that the product to be sleeved on the first mounting plate 123 is also moved to the first preset crimping position along the first preset direction.

[0066] Step 513: The displacement assembly of the first positioning device is used to control the product to be sleeved to move to the intermediate sleeve until the intermediate sleeve is sleeved in the middle of the product to be sleeved, and the second positioning device is used to place the product to be sleeved with the intermediate sleeve.

[0067] In some embodiments, after the product to be sleeved reaches the first preset crimping position, the first power assembly 125 continues to output power, which is transmitted to the push plate 1243 through the first transmission assembly 126, or the second transmission assembly continues to output power, which is transmitted to the push plate 1243, so that the push plate 1243 pushes the product to be sleeved along the first preset direction and moves to the intermediate sleeve, and finally the intermediate sleeve is sleeved in the middle of the product to be sleeved. At this time, the intermediate sleeve and the product to be sleeved are located on the third support 1341 of the second positioning device 130, and the first positioning device 120 is withdrawn.

[0068] Step 520: The crimping machine is used to crimp the middle of the product to be sleeved and the intermediate sleeve, and a first crimping signal is generated.

[0069] In some embodiments, the intermediate sleeve close to the crimping machine 110 is crimped by the crimping machine 110, so that the intermediate sleeve is crimped on the product to be sleeved, and a first crimping signal is generated.

[0070] In addition, after the first crimping signal is generated once, the second positioning device 130 can move the intermediate sleeve device along the first preset direction to the crimping machine 110 again, so that the crimping machine 110 can crimp the other end of the intermediate sleeve device, thereby generating the first crimping signal again.

[0071] Step 530: In response to the first crimping signal, the intermediate crimped product to be sleeved and the end sleeve device are moved to the second preset crimping position for sleeving.

[0072] In some embodiments, upon receiving the first crimping signal, the automatic positioning crimping system considers that the intermediate sleeve device has been sleeved at the intermediate position of the product to be sleeved and the crimping has been completed. At this time, the automatic positioning crimping system will start to control the third positioning device 140 to perform the sleeving procedure of the end sleeve device. The specific steps can be referred to steps 531 to 533.

[0073] Step 531: In response to the first crimping signal, the third power component of the second positioning device is used to move the crimped product to be sleeved to the second preset crimping position.

[0074] In some embodiments, the first moving component 138 is controlled to move the crimped product to be sleeved to the height of the second preset crimping position, and then the third power component 135 of the second positioning device 130 is controlled to output power, which is transmitted to the second mounting plate 133 through the second transmission component 136, so that the second mounting plate 133 moves on the second guide rail 132 and along the first preset direction, thereby driving the crimped product to be sleeved to also move along the first preset direction, so as to move the crimped product to be sleeved to the second preset crimping position. In this process, the abutting component 137 always abuts the end of the intermediate sleeve device away from the crimping machine 110.

[0075] Step 532: The first-stage telescopic component of the third positioning device is used to control the second-stage telescopic component to move to the second preset crimping position.

[0076] In some embodiments, the fifth power component 1423 of the first-stage telescopic component outputs power, which is transmitted to the third mounting plate 1422 through the third transmission component 1424, so that the third mounting plate 1422 moves on the third guide rail 1421 and along the first preset direction, thereby driving the second-stage telescopic component to also move along the first preset direction, and moving the second-stage telescopic component to the second preset crimping position.

[0077] Step 533: The first cylinder of the third positioning device is used to control the end sleeve device on the first base to move to one end of the intermediate crimped product to be sleeved, or the second cylinder of the third positioning device is used to control the end sleeve device on the second base to move to one end of the intermediate crimped product to be sleeved, until the end sleeve device is sleeved on one end of the intermediate crimped product to be sleeved.

[0078] In some embodiments, after moving the secondary telescopic assembly to the second preset crimping position, the end sleeve on the first base 1431 is moved on the fourth guide rail 1425 and in the first preset direction by the first cylinder 1427 of the third positioning device 140, and moves towards one end of the middle crimped product to be sleeved, so that the end sleeve on the first base 1431 is sleeved on one end of the product to be sleeved. Alternatively, the end sleeve on the second base 1432 is moved on the fifth guide rail 1426 and in the first preset direction by the second cylinder 1428 of the third positioning device 140, and moves towards one end of the middle crimped product to be sleeved, so that the end sleeve on the second base 1432 is sleeved on one end of the product to be sleeved.

[0079] Step 540: Crimping the end sleeve on the first base 1431 on one end of the product to be sleeved by the crimping machine 110, and generating a second crimping signal.

[0080] In some embodiments, the end sleeve on the first base 1431 is crimped on one end of the product to be sleeved by the crimping machine 110, and a second crimping signal is generated. Alternatively, the end sleeve on the second base 1432 is crimped on one end of the product to be sleeved by the crimping machine 110, and a second crimping signal is generated.

[0081] In some embodiments, when one of the end sleeves on the base 143 is completed, the second positioning device 130 and the third positioning device 140 are controlled to retreat, and the two ends of the product to be sleeved are exchanged in position by the mechanical hand and then placed on the third support 1341 again. The product to be sleeved is moved to the second preset crimping position by the aforementioned step 531, the other end sleeve is moved to the second preset crimping position for sleeving by the aforementioned step 533, and the end sleeve is crimped on the other end of the product to be sleeved by step 540, and a second crimping signal is generated again.

[0082] Step 550: Based on the judgment result of the number of received first crimping signals and second crimping signals and the preset number, it is determined whether the product to be sleeved is crimped.

[0083] In some embodiments, the automatic positioning and crimping system stores crimping programs of different models of cross arm products, so that the automatic positioning and crimping system can determine the preset number of the corresponding cross arm product according to the crimping program of the cross arm product. In actual execution process, when the crimping number of a cross arm product is the same as the preset number, the cross arm product can be taken down, the automatic positioning and crimping system can be reloaded, and the next product production can be started.

[0084] In a specific application scenario, the first positioning device 120 and the third positioning device 140 are located on the same side of the crimping machine 110, and the first positioning device 120 and the third positioning device 140 are located on the same base, the bottom of the base is provided with a driving assembly, and the second positioning device 130 is located on the other side of the crimping machine 110. The product to be sleeved is a core rod, the intermediate sleeve is an intermediate fitting, and the end sleeve includes a first end fitting and a second end fitting. The core rod is placed on the first support 1241 and the second support 1242 of the first positioning device 120, the intermediate fitting is placed on the third support 1341 of the second positioning device 130, the first end fitting is placed on the first base 1431, and the second end fitting is placed on the second base 1432. In the automatic positioning and crimping system, the first preset crimping signal of the core rod and the intermediate fitting is twice, and the second preset crimping signal of the core rod and the first end fitting and the second end fitting is twice.

[0085] The automatic positioning and crimping system is started, the sixth power assembly of the driving assembly controls the movement of the base, and the first positioning device 120 is first moved to a position aligned with the crimping machine 110. At this time, the limiting assembly 134 of the second positioning device 130 limits and fixes the intermediate fitting, so that the intermediate fitting abuts against the baffle 1342 along the second preset direction, and the abutting assembly 137 abuts against one end of the intermediate fitting away from the crimping machine 110, so that the intermediate sleeve abuts against the baffle 1342 along the first preset direction. Then control the first moving assembly 138 to lift the intermediate fitting to the height of the first preset crimping position, and then use the third power assembly 135 to move the intermediate fitting to the first preset crimping position along the first preset direction. At this time, the first power assembly 125 of the first positioning device 120 controls the first mounting plate 123 to move along the first preset direction until the core rod moves to the first preset crimping position. The first power assembly 125 continues to output power and transmits it to the push plate 1243 through the first transmission assembly 126, or the second transmission assembly continues to output power and transmits it to the push plate 1243, so that the push plate 1243 pushes the core rod to pass through the intermediate fitting, and the intermediate fitting is sleeved on the middle part of the core rod. The end of the intermediate fitting close to the crimping machine 110 is crimped by the crimping machine 110, and a first crimping signal is generated. The first positioning device 120 retreats, and the core rod is located on the second positioning device 130.

[0086] The first moving assembly 138 of the second positioning device 130 adjusts the height of the crimped core rod to the second preset crimping position, and the third power assembly 135 of the second positioning device 130 controls the crimped core rod to move to the second preset crimping position along the first preset direction. The driving assembly controls the first positioning device 120 to move out of the sleeving position, and the first end fitting on the third positioning device 140 is moved to align with the crimping machine 110. The second moving assembly 144 of the third positioning device 140 raises the end fitting to the height of the second preset crimping position. The fifth power assembly 1423 of the first telescopic assembly controls the second telescopic assembly to move to the second preset crimping position along the first preset direction, and the first cylinder 1427 of the third positioning device 140 controls the first end fitting on the first base 1431 to move towards one end of the core rod, so that the first end fitting is sleeved on one end of the core rod. The crimping machine 110 crimps the first end fitting on one end of the core rod, and generates a first second crimping signal.

[0087] At this time, the second positioning device 130 retreats, and the core rod is still located on the second positioning device 130. The mechanical arm exchanges the positions of the two ends of the core rod, so that the other end of the core rod aligns with the crimping machine 110, and moves the core rod to the second preset crimping position along the first preset direction. The driving assembly controls the second end fitting on the third positioning device 140 to move to align with the crimping machine 110. The second cylinder 1428 of the third positioning device 140 controls the second end fitting on the second base 1432 to move towards the other end of the core rod, so that the second end fitting is sleeved on the other end of the core rod. The crimping machine 110 crimps the second end fitting on the other end of the core rod, and generates a second second crimping signal.

[0088] The first moving assembly 138 of the second positioning device 130 adjusts the height of the core rod to the first preset crimping position again, and the third power assembly 135 controls the core rod to move to the first preset crimping position along the first preset direction. The crimping machine 110 also crimps the other end of the intermediate fitting on the middle part of the core rod, and generates a second first crimping signal.

[0089] The automatic positioning and crimping system counts that the first crimping signal is received twice, and the second crimping signal is received twice, which is consistent with the preset crimping times, so the production of the cross arm product is completed. It can be understood that the generation order of the two first crimping signals and the two second crimping signals can be adjusted according to the specific production rhythm, as long as the final statistical result is consistent with the preset crimping times, and specific limitations are not made here.

[0090] In the present application, the first positioning device is used to transport the product to be sleeved to a first preset crimping position, and the second positioning device is used to transport the intermediate sleeve to the first preset crimping position to sleeve and crimp the product to be sleeved, after the crimping of the intermediate sleeve is completed, the second positioning device is used to transport the product to be sleeved with the intermediate sleeve to a second preset crimping position, and the third positioning device is used to transport the end sleeve to the second preset crimping position to sleeve and crimp the end sleeve at the end of the product to be sleeved. The first positioning device, the second positioning device and the third positioning device can effectively control the crimping position of the product to be sleeved and each sleeve, ensure the standardization and uniformity of the crimping position, improve the quality of the product, and also improve the production efficiency compared with the manual method.
