[0038] Referring to Figures 1 to 3 , the high-precision detection structure of the utility model will be described below.

[0039] As Figures 1 to 3 shown, the high-precision detection structure 100 of the utility model embodiment comprises a workbench 110, and the workbench 110 is provided with a bearing base 200, a clamping mechanism 300, a jig 400, a control mechanism and a detection device.

[0040] It can be understood that the bearing base 200 is provided with a station 210, as Figures 1 to 3 shown, the workpiece is placed on the station 210.In this embodiment, the workpiece is a lens product.

[0041] It can be understood that the output end of the clamping mechanism 300 is connected with a clamping piece 310, as Figures 1 to 3When the workpiece is placed on the work station 210, the clamping mechanism 300 is started, the output end of the clamping mechanism 300 drives the clamping member 310 to clamp the workpiece on the work station 210, i.e. the workpiece and the abutting base 200 are relatively fixed. When the clamping mechanism 300 is started again, the output end of the clamping mechanism 300 drives the clamping member 310 to retract, the clamping member 310 releases the workpiece, and the workpiece can be placed on the work station 210.

[0042] It can be understood that the workbench 110 is also provided with a driving mechanism 600, as shown in the figure. Figures 1 to 3 The workbench 110 and the driving mechanism 600 are relatively fixed, the output end of the driving mechanism 600 is connected with the jig 400 to drive the jig 400 to move linearly along the first direction, so that the jig 400 approaches the workpiece and is connected with the workpiece, facilitating the production of the workpiece by the processing, detection or assembly structure on the jig 400. The output end of the driving mechanism 600 can also make the jig 400 away from the workpiece, facilitating the taking and placing of the workpiece on the work station 210 or adjusting the position of the workpiece.

[0043] It can be understood that the control mechanism is electrically connected with the clamping mechanism 300, so that the control mechanism can control the switch of the clamping mechanism 300. The control mechanism is also electrically connected with the driving mechanism 600, so that the control mechanism can control the switch of the driving mechanism 600.

[0044] It can be understood that the detection device is used to detect whether the workpiece and the jig 400 are connected in place. Specifically, the detection device and the control mechanism are electrically connected, when the detection device detects that the workpiece and the jig 400 are connected in place, the detection device sends a first signal to the control mechanism, facilitating the control mechanism to start the equipment on the jig 400 to detect or process the workpiece. When the detection device detects that the workpiece and the jig 400 are not connected in place, the control mechanism starts the clamping mechanism 300 and the driving mechanism 600, so that the clamping member 310 releases the workpiece and the jig 400 is away from the workpiece, facilitating the worker to adjust the position of the workpiece on the work station 210.

[0045] In this way, the workpiece is placed on the work station 210 of the abutting base 200, the clamping mechanism 300 is started, the clamping member 310 clamps the workpiece, the driving mechanism 600 is started, and the jig 400 moves along the first direction and connects the workpiece. After the driving mechanism 600 stops, the detection device detects whether the workpiece and the jig 400 are connected in place, if the workpiece and the jig 400 are not connected in place, the control mechanism starts the clamping mechanism 300 and the driving mechanism 600, so that the clamping member 310 releases the workpiece and the jig 400 is away from the workpiece, and the worker adjusts the position of the workpiece on the work station 210.

[0046] When the workpiece is adjusted, the clamping mechanism 300 and the driving mechanism 600 are restarted until the detection device detects that the workpiece and the jig 400 are connected in place. At this time, the detection device sends a first signal to the control mechanism, and the control mechanism can start the equipment on the jig 400 to detect or process the workpiece.

[0047] In the embodiment, the first direction is the front-back direction. When the driving mechanism 600 drives the jig 400 to move forward, the jig 400 is connected to the workpiece. When the driving mechanism 600 drives the jig 400 to move backward, the jig 400 is away from the workpiece, and the worker can take and place the workpiece on the supporting base 200. The driving mechanism 600 can be a linear motion mechanism such as a pneumatic cylinder, an oil cylinder, or an electric cylinder, which is not limited here.

[0048] In some embodiments, when the detection device detects that the workpiece and the jig 400 are not connected in place, if the control mechanism cannot obtain the first signal sent by the detection device within a set time, the control mechanism automatically starts the clamping mechanism 300 and the driving mechanism 600.

[0049] In other embodiments, when the detection device detects that the workpiece and the jig 400 are not connected in place, the detection device sends a second signal to the control mechanism, and the control mechanism starts the clamping mechanism 300 and the driving mechanism 600 after receiving the second signal.

[0050] It can be understood that the control mechanism can be a single-chip microcomputer or a PCL controller, which can simply realize the on-off control of the clamping mechanism 300 and the driving mechanism 600. It should be noted that the control mode of the control mechanism does not belong to the protection scope of the utility model, but belongs to the prior art. The utility model mainly protects the connection mode of the control mechanism.

[0051] It can be understood that the detection device includes a first detection mechanism 510 electrically connected to the control mechanism, as shown in FIGS. 5 and 6, the first detection mechanism 510 is used to detect whether the jig 400 is moved in place. Specifically, the first detection mechanism 510 is arranged on the supporting base 200, that is, the first detection mechanism 510 and the supporting base 200 are relatively fixed. If the jig 400 can be detected by the first detection mechanism 510 after being connected to the workpiece, the first detection mechanism 510 sends a first signal to the control mechanism. Figure 1 Figure 2

[0052] ​​When the workpiece is not installed in place on the work station 210, the driving mechanism 600 drives the jig 400 to connect the workpiece, and the connection position of the jig 400 and the workpiece is prone to be in advance, so that the first detection mechanism 510 cannot detect the jig 400. Therefore, if the first detection mechanism 510 cannot detect the jig 400, the control mechanism starts the clamping mechanism 300 and the driving mechanism 600, so that the clamping member 310 is loosened, the jig 400 is moved backward, and the worker adjusts the position of the workpiece on the work station 210 until the first detection mechanism 510 detects the jig 400.

[0053] In the embodiment, the first detection mechanism 510 is a proximity switch, the detection accuracy of the proximity switch is 0.5 mm, and the repeat accuracy is 0.1 mm. The jig 400 is accurately detected whether it is moved in place, so as to determine whether the workpiece is installed in place on the work station 210.

[0054] It can be understood that the detection device comprises a second detection mechanism 520 electrically connected with the control mechanism, as shown in Figure 1 and Figure 2 The second detection mechanism 520 is used to detect whether the interval between the workpiece and the jig 400 is within the set interval. Specifically, the second detection mechanism 520 is arranged on the jig 400, that is, the second detection mechanism 520 and the jig 400 are relatively fixed. If the jig 400 is connected to the workpiece, and the second detection mechanism 520 detects that the interval between the workpiece and the jig 400 is within the set interval, the second detection mechanism 520 sends a first signal to the control mechanism.

[0055] When the workpiece is not installed in place on the work station 210, the jig 400 is connected to the workpiece, and the connection between the jig 400 and the workpiece may be deviated, so that the second detection mechanism 520 detects that the interval between the workpiece and the jig 400 is not within the set interval. Therefore, if the second detection mechanism 520 detects that the interval is not within the set interval, the control mechanism starts the clamping mechanism 300 and the driving mechanism 600, so that the clamping member 310 is loosened, the jig 400 is moved backward, and the worker adjusts the position of the workpiece on the work station 210 until the interval detected by the second detection mechanism 520 is within the set interval.

[0056] Further, the second detection mechanism 520 is provided with two and arranged at intervals along a second direction, as shown in Figure 2 The second direction is perpendicular to the first direction, and the two second detection mechanisms 520 respectively detect whether the intervals of the workpiece and the jig 400 at two ends along the second direction are within the set interval. If the detection intervals of the two second detection mechanisms 520 are both within the set interval, the two second detection mechanisms 520 respectively send a first signal to the control mechanism. At this time, the connected workpiece and the jig 400 are basically parallel, which further ensures that the workpiece is installed in place on the work station 210.

[0057] It can be understood that when the control mechanism does not receive the first signals sent by the two second detection mechanisms 520 respectively, the control mechanism starts the clamping mechanism 300 and the driving mechanism 600, so that the worker adjusts the mounting position of the workpiece.

[0058] In some embodiments, the second direction is the up-down direction, and the two second detection mechanisms 520 are respectively used to detect whether the upper end and the lower end connected by the workpiece and the jig 400 are within the set interval.

[0059] In this embodiment, the second direction is the left-right direction, and the two second detection mechanisms 520 are respectively used to detect whether the left end and the right end connected by the workpiece and the jig 400 are within the set interval,

[0060] In this embodiment, the second detection mechanism 520 is a contact sensor, the detection stroke of the contact sensor is 1.5 millimeters, and the repeat accuracy is 3 microns. By accurately detecting the interval between the workpiece and the jig 400, it is determined whether the workpiece is mounted in place on the work station 210.

[0061] It can be understood that the detection device includes a third detection mechanism electrically connected to the control mechanism, and the third detection mechanism is used to detect the relative position of the workpiece and the jig 400. Specifically, as shown in Figure 2 and Figure 3 The third detection mechanism includes a transmitting end 531 and a receiving end 532, and the transmitting end 531 and the receiving end 532 are respectively arranged at opposite ends of the jig 400 along the linear direction, that is, the transmitting end 531 and the receiving end 532 are respectively fixed opposite to the jig 400, and the transmitting end 531 and the receiving end 532 are arranged in a linear interval.

[0062] It can be understood that the transmitting end 531 sends a linear signal, and if there is no workpiece blocking in the middle, the receiving end 532 sends a first signal to the control mechanism after receiving the signal sent by the transmitting end 531. If the workpiece is not installed in place or the workpiece is of other series or model, when the workpiece and the jig 400 are connected, the linear signal sent by the transmitting end 531 will be blocked by the workpiece, causing the receiving end 532 to be unable to receive the signal emitted by the transmitting end 531. At this time, the control mechanism controls the clamping mechanism 300 and the driving mechanism 600, so that the worker can adjust the mounting position of the workpiece or replace the corresponding workpiece, so that the workpiece is installed with high precision, and prevents other workpieces from entering the production and processing or detection operation of this type of workpiece.

[0063] It can be understood that the transmitting end 531 and the receiving end 532 are arranged in an interval along the second direction. In this embodiment, the transmitting end 531 is arranged at the left end of the jig 400, and the receiving end 532 is arranged at the right end of the jig 400.

[0064] In the embodiment, the third detecting mechanism is an infrared reflection sensor, which monitors in real time by emitting and receiving infrared light in a non-contact manner, so that the control mechanism can be fed back in time when the workpiece installed in the work station 210 has a defect, thereby avoiding improper operation of the worker.

[0065] It can be understood that the control mechanism is electrically connected with an alarm. When the detecting device detects that the workpiece is not in place, the control mechanism also starts the alarm to prompt the worker to adjust the workpiece.

[0066] In some embodiments, the first detecting mechanism 510, the second detecting mechanism 520 and the third detecting mechanism are detected in sequence, and when the control mechanism does not receive the first signal sent by the first detecting mechanism 510, the second detecting mechanism 520 or the third detecting mechanism, the control mechanism starts the alarm.

[0067] In some other embodiments, the first detecting mechanism 510, the second detecting mechanism 520 and the third detecting mechanism are detected simultaneously, and when the control mechanism does not receive the first signal sent by the first detecting mechanism 510, the second detecting mechanism 520 and the third detecting mechanism simultaneously, the control mechanism starts the alarm.

[0068] It can be understood that the alarm can be one of an audible and light alarm, a light alarm or a sound alarm, which does not make specific limitation here, and the alarm prompts the worker by emitting light and / or sound to adjust the workpiece on the work station 210 in time.

[0069] It can be understood that the supporting base 200 is provided with a plurality of supporting bases 200 arranged at intervals along the first direction, as shown in Figure 1 and Figure 2 The plurality of supporting bases 200 form a work station 210 for placing one workpiece, so that the workpiece is stably placed in the work station 210.

[0070] In the embodiment, the supporting base 200 is provided with two supporting bases 200 arranged at intervals along the front and back directions, as shown in Figure 1 and Figure 2

[0071] It can be understood that the supporting base 200 is provided with a positioning member 220 for positioning the workpiece, as shown in Figures 1 to 3 When the workpiece is placed on the work station 210, the workpiece is connected and fixed with the supporting base 200 through the positioning member 220, further improving the stability of the connection between the supporting base 200 and the workpiece.

[0072] In the embodiment, the positioning member 220 is a pin, which extends along the up and down directions and has a lower end connected to the supporting base 200. When the workpiece is installed in the work station 210, the workpiece can be positioned by the edge abutting against the cylindrical wall surface of the pin, and the workpiece can also be positioned by being inserted into the pin. ​

[0073] In some embodiments, the clamping mechanism 300 can be connected to the workbench 110. Since the supporting base 200 is also connected to the workbench 110, the clamping mechanism 300 and the supporting base 200 are relatively fixed, and the clamping mechanism 300 can firmly clamp the workpiece on the work station 210.

[0074] In the present embodiment, the supporting base 200 is connected with the clamping mechanism 300. Specifically, the supporting base 200 is connected with the clamping mechanism 300 at both ends of the work station 210, i.e., the left end and the right end of each supporting base 200 are connected with the clamping mechanism 300, as shown in Figure 3

[0075] In this way, when the workpiece is placed on the work station 210, the two clamping mechanisms 300 connected with the supporting base 200 clamp the left end and the right end of the workpiece, respectively, and the two supporting bases 200 provide support to the workpiece from the front and back directions, respectively, in cooperation with the positioning member 220, so that the workpiece can be firmly installed on the work station 210.

[0076] It can be understood that the clamping mechanism 300 is a linear motion mechanism such as a pneumatic cylinder, an oil cylinder or an electric cylinder, which is not specifically limited herein.

[0077] It can be understood that the clamping member 310 includes a first connecting end 311, a second connecting end 312 and a clamping end 313 arranged in a straight line. Specifically, the first connecting end 311 is hingedly connected with the output end of the clamping mechanism 300, and a connecting member 320 is arranged between the clamping member 310 and the clamping mechanism 300. The connecting member 320 extends in the up-down direction, the upper end of the connecting member 320 is hingedly connected with the second connecting end 312, and the lower end of the connecting member 320 is hingedly connected with the clamping mechanism 300, as shown in Figure 1 and Figure 2

[0078] In this way, the second connecting end 312 is located between the first connecting end 311 and the clamping end 313, and the output end of the clamping mechanism 300 drives the first connecting end 311 to move in the up-down direction. When the first connecting end 311 is driven to move upward, the clamping end 313 rotates downward about the second connecting end 312 and abuts against the workpiece. When the first connecting end 311 is driven to move downward, the clamping end 313 rotates upward about the second connecting end 312 and releases the workpiece, so that the workpiece can be taken out or placed in.

[0079] Working principle of the high-precision detection structure 100:

[0080] Step one, place the workpiece on the work station 210 formed by the two supporting bases 200, and position it by means of the pin, and then start the clamping mechanism 300 to clamp the workpiece by the clamping member 310.

[0081] ​​Step two, the driving mechanism 600 is started, the jig 400 is connected to the workpiece, the first detection mechanism 510 detects whether the jig 400 is moved to the position, if the first detection mechanism 510 cannot detect the jig 400, the control mechanism starts the clamping mechanism 300, the driving mechanism 600 and the alarm, and the worker adjusts the position of the workpiece, and the step one is repeated until the first detection mechanism 510 sends the first signal to the control mechanism.

[0082] Step three, the second detection mechanism 520 detects whether the interval between the workpiece and the jig 400 is at the set interval, if not, the control mechanism starts the clamping mechanism 300, the driving mechanism 600 and the alarm, and the worker adjusts the workpiece, and the step one and the step two are repeated until the second detection mechanism 520 sends the first signal to the control mechanism.

[0083] Step four, the third detection mechanism detects the relative position of the workpiece and the jig 400, when the receiving end 532 cannot receive the straight line signal sent by the transmitting end 531, the control mechanism starts the clamping mechanism 300, the driving mechanism 600 and the alarm, and the worker adjusts the position of the workpiece, and the step one to the step three are repeated until the third detection mechanism sends the first signal to the control mechanism.
