[0002] During the surface processing of the ring-shaped workpiece, the first fixture used includes multiple string rods, each of which is vertically sleeved with multiple workpieces, so that a single first fixture can simultaneously complete the transportation of multiple workpieces.

[0003] When the loading module loads the workpiece onto the string rod in the first fixture, normally, after the loading module loads the workpieces of the same batch onto the first fixture, the string rods on the first fixture are just fully loaded. However, when the loading module is loading, there are omissions. At this time, there will be workpieces that cannot be loaded onto the string rod. Since the workpieces on the string rod are not fully loaded, when the double-sided grinding module performs surface processing on the workpiece on this string rod, the workpiece on the string rod is easy to move up and down, thereby affecting the processing effect of the double-sided grinding module on the workpiece on the string rod.

[0049] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0051] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0052] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0053] Reference below Figures 1 to 13 The double-sided grinding equipment of the first aspect of the present application is described in detail.

[0054] refer to Figure 1 According to the double-sided grinding device of the first embodiment of the present invention, it includes a double-sided grinding module group 100, a loading module 200, a unloading module 300, a first detection module 400, a second detection module 500 and a circulating conveyor line 600; the double-sided grinding module group 100 is used to perform double-sided grinding on the workpiece; the loading module 200 is used to load the workpiece onto the string rod of the first fixture; the unloading module 300 is used to unload the workpiece on the first fixture; the first detection module 400 is used to detect whether the string rod is fully loaded with workpieces; the second detection module 500 is used to detect whether the string rod is empty; the circulating conveyor line 600 is used to drive the first fixture to circulate through the loading module 200, the first detection module 400, the double-sided grinding module group 100, the unloading module 300 and the second detection module 500.

[0055] Furthermore, when the double-sided grinding equipment of this embodiment is working, under the conveyance of the circulating conveyor line 600, the first fixture can circulate through the loading module 200, the first detection module 400, the double-sided grinding module 100, the unloading module 300 and the second detection module 500, and in this process, the loading module 200 can load the workpiece onto the string rod on the first fixture, the first detection module 400 can detect the string rod on the first fixture to detect whether the string rod is fully loaded with workpieces, the double-sided grinding module 100 can perform surface processing on the workpiece on the first fixture, the unloading module 300 can unload the workpiece on the string rod of the first fixture, and the second detection module 500 can detect the string rod on the first fixture to detect whether the string rod is empty.

[0056] It should be noted that the first fixture is provided with a vertically extending string rod, and multiple workpieces can be passed through the string rod at the same time. After the string rod is fully loaded with workpieces, a nut needs to be installed on the upper end of the string rod; when the string rod is in a fully loaded state, the workpiece at the upper end of the string rod is in contact with the nut, and under the limitation of the nut, the workpieces on the string rod can be close to each other, and the gap between two adjacent workpieces on the string rod is small, and the workpiece on the string rod is difficult to vibrate in the vertical direction; when the workpiece on the string rod is not fully loaded, at this time, there is a certain gap between the workpiece at the upper end of the string rod and the nut, and the workpiece on the string rod is prone to vibrate in the vertical direction, thereby affecting the processing effect of the double-sided grinding module 100 on the workpiece.

[0057] It can be understood that the setting of the first detection module 400 enables the first detection module 400 to detect the string rod on the first fixture after the loading module 200 loads the string rod of the first fixture before the first fixture enters the double-sided grinding module 100. The staff can understand the situation of the string rod on the first fixture in real time based on the detection results of the first detection module 400, so as to adjust the double-sided grinding equipment in time when the string rod is not fully loaded, thereby replenishing the workpiece on the underloaded string rod in time to ensure the subsequent processing effect of the double-sided grinding module 100 on the workpiece.

[0058] It can be understood that the setting of the second detection module 500 enables the second detection module 500 to detect the string rod on the first fixture before the first fixture enters the loading module 200 after the unloading module 300 unloads the string rod of the first fixture. The staff can understand the situation of the string rod on the first fixture in real time based on the detection results of the second detection module 500, so as to adjust the double-sided grinding equipment in time when there are still workpieces on the string rod that have not been unloaded, so as to unload the remaining workpieces on the string rod in time, so as to ensure the subsequent loading effect of the loading module 200 on the workpiece and reduce the possibility of excessive loading of workpieces on the string rod.

[0059] In some embodiments of the present invention, reference Figure 2 and Figure 3The first detection module 400 includes a lifting assembly 410, a first mounting seat 420, a detection piece 430 and a sensor 440. The detection piece 430 is slidably arranged on the first mounting seat 420 in a vertical direction. The lifting assembly 410 is connected to the first mounting seat 420. The sensor 440 is arranged on the first mounting seat 420 and is used to detect the moving distance of the detection piece 430 relative to the first mounting seat 420. Under the drive of the lifting assembly 410, the first mounting seat 420 can drive the detection piece 430 to squeeze the workpiece on the string rod downward.

[0060] It should be noted that, in the process of the lifting assembly 410 driving the first mounting seat 420 to descend a first distance, the detection member 430 will first abut against the workpiece at the upper end of the string rod, and then the detection member 430 will remain stationary under the abutment of the workpiece, while the first mounting seat 420 will continue to move downward driven by the lifting assembly 410, thereby causing the detection member 430 and the first mounting seat 420 to produce a relative movement of a second distance in the vertical direction. If the string rod is in a fully loaded state, the height of the workpiece at the upper end of the string rod is certain, and the second distance can reach the preset distance at this time. If the string rod is not in a fully loaded state, the height of the workpiece at the upper end of the string rod is lower, and the second distance is numerically smaller than the preset distance.

[0061] It can be understood that when the first detection module 400 of this embodiment needs to detect the string rod on the first fixture, the lifting assembly 410 drives the first mounting seat 420 to drop a first distance, and then detects the second distance moved by the detection member 430 relative to the first mounting seat 420 through the sensor 440. If the second distance reaches the preset distance, it indicates that the string rod is in a fully loaded state. If the second distance does not reach the preset distance, it indicates that the string rod is not in a fully loaded state.

[0062] Specifically, refer to Figure 2 The lifting assembly 410 includes a frame 411 and a lifting cylinder 412. The lifting cylinder 412 is arranged on the frame 411, and the output end of the lifting cylinder 412 is connected to the first mounting seat 420. Under the drive of the lifting cylinder 412, the first mounting seat 420 performs a lifting movement.

[0063] In some embodiments of the present invention, reference Figure 2 and Figure 3 The detection member 430 includes a sensing portion 431 , and the sensor 440 is disposed on the upper side of the sensing portion 431 . The sensor 440 includes a transmitting end 441 and a receiving end 442 . A detection channel 440 a is formed between the transmitting end 441 and the receiving end 442 to allow the sensing portion 431 to pass through.

[0064] It can be understood that when the string rod is in a fully loaded state, after the lifting assembly 410 drives the first mounting seat 420 to move downward a first distance, the detection member 430 can move upward a second distance relative to the first mounting seat 420. At this time, the sensing portion 431 of the detection member 430 can extend into the detection channel 440a, and the laser receiving end 442 emitted by the transmitting end 441 cannot receive it, and the sensor 440 detects that the string rod is in a fully loaded state; when the string rod is not in a fully loaded state, after the lifting assembly 410 drives the first mounting seat 420 to move downward a first distance, the detection member 430 moves upward a second distance relative to the first mounting seat 420. At this time, the sensing portion 431 of the detection member 430 still does not extend into the detection channel 440a, and the laser receiving end 442 emitted by the transmitting end 441 can receive it normally, and the sensor 440 detects that the string rod is not in a fully loaded state.

[0065] It should be noted that the first fixture includes multiple string rods, and the loading module 200 will load all the string rods on the first fixture.

[0066] Based on the above situation, in some embodiments of the present invention, reference Figure 2 and Figure 3 The first detection module 400 includes a plurality of detection elements 430 and a plurality of sensors 440 , and the detection elements 430 and the sensors 440 are arranged in a one-to-one correspondence.

[0067] It can be understood that since the first detection module 400 includes multiple detection parts 430 and multiple sensors 440, and the detection parts 430 and sensors 440 are set in a one-to-one correspondence, the corresponding detection parts 430 and sensors 440 can cooperate to complete the detection of a string rod on the first fixture. The setting of multiple detection parts 430 and multiple sensors 440 enables a single first detection module 400 to complete the detection of multiple string rods on the first fixture at a single time.

[0068] Furthermore, the number of detection parts 430 on the first detection module 400 is the same as the number of string rods on the first fixture, and the arrangement form of each detection part 430 in the first detection module 400 is the same as the arrangement form of each string rod on the first fixture, so that the first detection module 400 can complete the detection of all string rods on the first fixture in a single time.

[0069] In some embodiments of the present invention, reference Figure 3 The detection member 430 includes a detection portion 432, and the detection portion 432 is provided with an avoidance hole 432a allowing the string rod to pass through. The detection portion 432 is used to abut against the workpiece on the string rod.

[0070] It can be understood that the setting of the avoidance hole 432a on the detection part 432 allows the string rod to pass through the avoidance hole 432a during the process of the workpiece on the first fixture pushing the detection part 432 back, and guide the detection part 432 in the vertical direction, so that the detection part 432 can move stably in the vertical direction under the reverse push of the workpiece.

[0071] It should be noted that the specific structure of the second detection module 500 refers to that of the first detection module 400 .

[0072] In some embodiments of the present invention, reference Figure 1 The double-sided grinding equipment also includes a first conveyor line 700, which is provided with a workpiece loading area 701 and a workpiece unloading area 702. The first conveyor line 700 is used to convey the second fixture through the workpiece loading area 701 and the workpiece unloading area 702 in sequence. The loading module 200 is used to load the workpiece on the second fixture in the workpiece loading area 701 onto the string rod of the first fixture, and the unloading module 300 is used to unload the workpiece on the first fixture onto the second fixture in the workpiece unloading area 702.

[0073] Furthermore, after the first conveyor line 700 transports the second jig fully loaded with workpieces to the workpiece loading area 701, the loading module 200 can load the workpiece on the second jig onto the first jig of the circulating conveyor line 600. After the second jig in the workpiece loading area 701 is unloaded, the first conveyor line 700 transports the unloaded second jig from the workpiece loading area 701 to the workpiece unloading area 702, and the unloading module 300 can unload the processed workpiece on the first jig on the circulating conveyor line 600 onto the unloaded second jig.

[0074] It can be understood that the setting of the first conveyor line 700 enables the second fixture to supply the workpiece to the loading module 200 in the workpiece loading area 701, and then receive the processed workpiece unloaded by the unloading module 300 in the workpiece unloading area 702, so as to improve the working efficiency of the double-sided grinding equipment of the present application.

[0075] In some embodiments of the present invention, reference Figures 4 to 7The blanking module 300 includes a partition assembly 310, a first lifting assembly 320 and a blanking assembly 330; the partition assembly 310 includes a mounting frame 311, a partition 312, a limiter 313, a first driving structure 314, a second driving structure 315 and a third driving structure 316. The mounting frame 311 is provided with a vertically extending through hole 311a. The partition 312 and the limiter 313 are both slidably arranged on the mounting frame 311 in the left and right directions. The partition 312 is arranged on the lower side of the limiter 313, and a space is left between the partition 312 and the limiter 313 to allow a single workpiece to be accommodated. The first driving structure 314 is connected to the partition 312 and is used to drive the partition 312 to extend into or extend out of the through hole 311a in the left and right directions. The second driving structure 315 is connected to the limit member 313 and is used to drive the limit member 313 to extend into or extend out of the through hole 311a in the left and right directions. The third driving structure 316 is connected to the mounting bracket 311 and is used to drive the mounting bracket 311 to perform lifting movements. The first lifting assembly 320 is used to drive the workpiece on the string rod to gradually extend into the through hole 311a from bottom to top. The unloading assembly 330 is used to unload the workpiece at the top of the string rod.

[0076] It can be understood that when the blanking module 300 unloads the workpiece on the first fixture, the circulating conveyor line 600 can move the first fixture to the bottom of the mounting bracket 311. Driven by the third driving structure 316, the mounting bracket 311 moves downward so that the string rod on the first fixture is inserted into the through hole 311a. Then, the second driving structure 315 drives the limiting member 313 to extend into the through hole 311a in the left and right directions. The first lifting assembly 320 drives the workpiece on the string rod to rise so that the workpiece at the upper end of the string rod abuts against the lower end of the limiting member 313. Then, the first driving structure 314 drives the partition 312 to extend into the through hole 311 in the left and right directions. a, since the gap between the limiter 313 and the separator 312 can only accommodate a single workpiece, the separator 312 can separate the two workpieces at the upper end of the string rod, and then the second driving structure 315 drives the limiter 313 to extend out of the through hole 311a in the left and right directions, and the unloading assembly 330 unloads the workpiece at the upper end of the string rod, and then the second driving structure 315 drives the limiter 313 to extend into the through hole 311a in the left and right directions, and the first driving structure 314 drives the separator 312 to extend out of the through hole 311a in the left and right directions, and the first lifting assembly 320 drives the workpiece on the string rod to rise, in preparation for unloading the workpiece at the upper end of the string rod again.

[0077] In a further embodiment of the present invention, reference Figure 8The first lifting assembly 320 includes a lifting plate 321 and a fourth driving structure 322. The fourth driving structure 322 includes a second mounting seat 322a, a first driver 322b, a third mounting seat 322c and a second driver 322d. The second mounting seat 322a is provided with a first slide rail extending left and right, the lifting plate 321 is slidably provided on the first slide rail, the first driver 322b is provided on the second mounting seat 322a and is connected to the lifting plate 321, the first driver 322b is used to drive the lifting plate 321 to slide in the left and right directions, the third mounting seat 322c is provided with a second slide rail extending vertically, the second mounting seat 322a is slidably provided on the second slide rail, the second driver 322d is provided on the third mounting seat 322c and is connected to the second mounting seat 322a, and the second driver 322d is used to drive the lifting plate 321 to slide in the vertical direction.

[0078] It can be understood that under the drive of the first driver 322b, the lifting plate 321 can move in the horizontal direction so that the lifting plate 321 is inserted directly below the workpiece on the string rod, and under the drive of the second driver 322d, the lifting plate 321 can move in the vertical direction so that the lifting plate 321 drives the workpiece on the string rod to rise.

[0079] In some embodiments of the present invention, reference Figure 9 A lifting assembly 710 is provided on the first conveyor line 700 . The lifting assembly 710 is provided in the workpiece loading area 701 and is used to lift the second fixture in the workpiece loading area 701 to a certain height.

[0080] It can be understood that the second fixture in the workpiece loading area 701 is lifted to a certain height by the lifting assembly 710, so that when a second fixture receives a workpiece in the workpiece loading area 701, other second fixtures on the first conveyor line 700 can pass through the workpiece loading area 701 smoothly.

[0081] Specifically, refer to Figure 9 The lifting assembly 710 includes a lifting structure 711 and a supporting structure 712. The lifting structure 711 includes a first lifting member 711a and a third driver 711b. The supporting structure 712 includes a supporting frame 712a, a fourth driver 712b and a supporting member 712c. The first lifting member 711a is connected to the third driver 711b and is used to drive the lifting member to perform lifting movements. The fourth driver 712b is provided on the supporting frame 712a and is connected to the supporting member 712c. The fourth driver 712b is used to drive the supporting member 712c to move in a horizontal direction.

[0082] It can be understood that when the second jig needs to receive the workpiece unloaded by the unloading module 300, the first conveyor line 700 conveys the second jig to the workpiece loading area 701, and the first lifting member 711a can drive the third driver 711b to rise, so that the lifting member drives the second jig to rise to a certain height, and then, the fourth driver 712b drives the supporting member 712c to move horizontally to directly below the second jig to carry the second jig, and then, the first lifting member 711a drives the third driver 711b to descend and reset. At this time, the unloading module 300 can smoothly unload the workpiece onto the second jig carried by the supporting member 712c; after the second jig is fully loaded, the first lifting member 711a drives the third driver 711b to rise to support the second jig, and the fourth driver 712b drives the supporting member 712c to move horizontally to avoid the second jig, and the first lifting member 711a drives the third driver 711b to descend to put the fully loaded second jig back on the first conveyor line 700.

[0083] In some embodiments of the present invention, reference Figure 1 The double-sided grinding equipment also includes a flipping module 800. A flipping area 703 is provided on the first conveyor line 700, and along the conveying direction of the first conveyor line 700, the flipping area 703 is provided on the rear side of the workpiece unloading area 702. The flipping module 800 is provided in the flipping area 703 and is used to flip the second fixture in the flipping area 703.

[0084] For further reference, Figures 10 to 12 The flip module 800 includes a supporting assembly 810, a second lifting assembly 820 and a flip assembly 830. The supporting assembly 810 includes a supporting frame 811, a fifth driver 812 and a supporting member 813. The fifth driver 812 is provided on the supporting frame 811 and connected to the supporting member 813. The fifth driver 812 is used to drive the supporting member 813 to move horizontally; the second lifting assembly 820 includes a sixth driver 821 and a second lifting member 822. The sixth driver 821 is connected to the second lifting member 822 and is used to drive the second lifting member 822 to move up and down; the flip assembly Component 830 includes a lifting structure 831, a rotating structure 832, a rotating frame 833, a first clamping structure 834 and a second clamping structure 835. The first clamping structure 834 and the second clamping structure 835 are both provided on the rotating frame 833. The first clamping structure 834 and the second clamping structure 835 can both clamp the second fixture. The output end of the rotating structure 832 is connected to the rotating frame 833 and is used to drive the rotating frame 833 to flip. The output end of the lifting structure 831 is connected to the rotating structure 832 and is used to drive the rotating structure 832 and the rotating frame 833 to perform lifting and lowering movements synchronously.

[0085] It can be understood that an empty second jig is supported on the supporting member 813. After the second conveyor line 1100 conveys the fully loaded second jig to the flipping area, the sixth driver 821 drives the second lifting member 822 to rise, so as to drive the fully loaded second jig to rise until the fully loaded second jig is stacked on the lower side of the empty second jig. Then, the fifth driver 812 drives the supporting member 813 to move horizontally to avoid the empty second jig. The empty second jig is completely stacked on the fully loaded second jig. Then, the lifting structure 831 drives the rotating frame 833 to move downward, so that the first clamping structure 834 clamps the empty second jig, and the second clamping structure 835 clamps the fully loaded second jig. Then, the lifting structure 831 drives the rotating frame 833 to rise, and the rotating structure 832 drives the rotating frame 833 to flip 180° so that the workpiece on the fully loaded second fixture is flipped onto the unloaded second fixture. At this time, the lower second fixture is fully loaded with the flipped workpiece, and the upper second fixture is in an unloaded state. Then, the lifting structure 831 drives the rotating frame 833 to descend to place the two second fixtures on the second lifting member 822. The fifth driver 812 drives the supporting member 813 to move horizontally between the two second fixtures and carry the second fixture on the upper side. The sixth driver 821 drives the second lifting member 822 to descend to place the second fixture on the lower side back onto the second conveyor line 1100.

[0086] In some embodiments of the present invention, reference Figure 1 The double-sided grinding equipment also includes a nut assembly module 900 and a nut disassembly module 1000. The nut assembly module 900 is used to assemble nuts on the string rod, and the nut disassembly module 1000 is used to disassemble the nuts on the string rod. The circulating conveyor line 600 is used to drive the first fixture to circulate through the loading module 200, the first detection module 400, the nut assembly module 900, the double-sided grinding module 100, the nut disassembly module 1000, the unloading module 300 and the second detection module 500.

[0087] It can be understood that before the circulating conveyor line 600 conveys the first jig into the double-sided grinding module 100, the nut assembly module 900 can install nuts on the string rod of the first jig to prevent the workpiece on the string rod from detaching upward from the string rod; before the circulating conveyor line 600 conveys the first jig to the unloading module 300, the nut disassembly module 1000 can remove the nuts on the string rod to facilitate the subsequent unloading of the workpiece on the string rod by the unloading module 300.

[0088] In a further embodiment of the present invention, reference Figure 1The double-sided grinding equipment also includes a second conveyor line 1100, which is provided with a nut loading area 1101 and a nut unloading area 1102. The second conveyor line 1100 is used to convey the third fixture to circulate between the nut loading area 1101 and the nut unloading area 1102. The nut assembly module 900 is used to assemble the nuts in the nut unloading area 1102 onto the string rod, and the nut disassembly module 1000 is used to unload the nuts on the string rod into the nut unloading area 1102.

[0089] Furthermore, after the nut disassembly module 1000 disassembles the nuts on the string rod, it can place the nuts on the third jig in the nut unloading area 1102. After the third jig is fully loaded, the second conveyor line 1100 can convey the third jig in the nut unloading area 1102 to the nut loading area 1101. At this time, the nuts on the third jig can be supplied to the nut assembly module 900.

[0090] It can be understood that the setting of the second conveyor line 1100 enables the nuts removed from the string rod by the nut disassembly module 1000 to be used again by the nut assembly module 900, thereby improving the degree of automation of the double-sided grinding equipment of the present application.

[0091] In some embodiments of the present invention, reference Figure 1 The double-sided grinding equipment also includes a correction module 1200. Along the conveying direction of the circulating conveyor line 600, the correction module 1200 is arranged between the unloading module 300 and the loading module 200. The correction module 1200 is used to correct the verticality of the string rod on the first fixture.

[0092] It is understandable that if the string rod is in an inclined state, it is difficult for the loading module 200 to put the workpiece on the string rod, thereby affecting the accuracy of the loading module 200 in loading the string rod; in this embodiment, by setting the correction module 1200, before the loading module 200 loads the string rod on the first fixture, the correction module 1200 can correct the verticality of the string rod of the first fixture, so that the subsequent loading module 200 can smoothly load the workpiece onto the string rod.

[0093] Specifically, refer to Figure 13The correction module 1200 includes a clamping assembly 1210 and an adjusting assembly 1220; the clamping assembly 1210 includes a seventh driver 1211, a first clamping jaw 1212 and a second clamping jaw 1213, the seventh driver 1211 is respectively connected to the first clamping jaw 1212 and the second clamping jaw 1213, and is used to drive the first clamping jaw 1212 and the second clamping jaw 1213 to move closer or farther synchronously; the adjusting assembly 1220 includes a frame 1221, an eighth driver 1222 and an adjusting seat 1223, the adjusting seat 1223 is slidably arranged on the frame 1221 along the left and right directions, the clamping assembly 1210 is arranged on the adjusting seat 1223, the eighth driver 1222 is arranged on the frame 1221 and is connected to the adjusting seat 1223, and the eighth driver 1222 is used to drive the adjusting seat 1223 to move along the left and right directions.

[0094] It can be understood that when the correction module 1200 is working, the seventh driver 1211 can drive the first clamp 1212 and the second clamp 1213 away from each other. Under the drive of the eighth driver 1222, the clamping assembly 1210 approaches the string rod in the left and right directions so that the string rod extends between the first clamp 1212 and the second clamp 1213. Then, the seventh driver 1211 drives the first clamp 1212 and the second clamp 1213 to approach each other to clamp and correct the string rod. Then, the seventh driver 1211 drives the first clamp 1212 and the second clamp 1213 away from each other, and the eighth driver 1222 drives the clamping assembly 1210 away from the string rod in the left and right directions.

[0095] Reference below Figure 14 The detection method according to the second aspect of the present invention is described in detail.

[0096] refer to Figure 14 According to the detection method provided in the second embodiment of the present invention, which is applied to the double-sided grinding equipment provided in the first embodiment of the present invention, the detection method includes but is not limited to the following steps:

[0097] Step S100: driving the first mounting base 420 to descend a first distance via the lifting assembly 410;

[0098] Step S200: Detecting, by the sensor 440, a second distance moved by the detection member 430 relative to the first mounting seat 420 under the reverse push of the workpiece on the string rod, and determining whether the second distance reaches a preset distance;

[0099] Step S300: If the second distance reaches the preset distance, it is determined that the workpiece on the string rod is fully loaded;

[0100] Step S400: If the second distance does not reach the preset distance, it is determined that the workpiece on the string rod is not fully loaded.

[0101] It should be noted that, in the process of the lifting assembly 410 driving the first mounting seat 420 to descend a first distance, the detection member 430 will first abut against the workpiece at the upper end of the string rod, and then the detection member 430 will remain stationary under the abutment of the workpiece, while the first mounting seat 420 will continue to move downward driven by the lifting assembly 410, thereby causing the detection member 430 and the first mounting seat 420 to produce a relative movement of a second distance in the vertical direction. If the string rod is in a fully loaded state, the height of the workpiece at the upper end of the string rod is certain, and the second distance can reach the preset distance at this time. If the string rod is not in a fully loaded state, the height of the workpiece at the upper end of the string rod is lower, and the second distance is numerically smaller than the preset distance.

[0102] It can be understood that when the first detection module 400 of this embodiment needs to detect the string rod on the first fixture, the lifting assembly 410 drives the first mounting seat 420 to drop a first distance, and then detects the second distance moved by the detection member 430 relative to the first mounting seat 420 through the sensor 440. If the second distance reaches the preset distance, it indicates that the string rod is in a fully loaded state. If the second distance does not reach the preset distance, it indicates that the string rod is not in a fully loaded state.

[0103] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
