Description

Technical Field

[0001] The present application relates to the technical field of positioning fixtures, and in particular to a photoelectric sensor positioning and installation fixture. Background Art

[0002] For some special product modules, such as medical modules, they need to be positioned and installed during the processing. However, due to the structural characteristics of the module itself, such as the front of the module cannot be subjected to pressure, the module can only be fixed and installed through several specific points when positioned and installed, and the entire module cannot be placed directly in the positioning fixture. The module cannot be placed flat and can only be placed in the air under force at the side. Usually, mounting columns are set on the module and mounting grooves are set on the positioning fixture. The mounting columns must be placed at the positioning points in the mounting grooves to achieve installation accuracy. However, usually the operator manually gropes and places the mounting columns at the positioning points of the positioning fixture mounting grooves, and uses fasteners to fix the mounting columns. This method easily causes the actual placement position of the mounting columns to deviate from the positioning points, thereby increasing the risk of module damage or defects. Summary of the invention

[0003] Based on this, it is necessary to provide a photoelectric sensor positioning and installation fixture to address the problem of poor module positioning accuracy of the positioning fixture.

[0004] The present application proposes a photoelectric sensor positioning and installation fixture, which is used for positioning and installing a module, wherein the module is provided with a mounting column, and the photoelectric sensor positioning and installation fixture comprises:

[0005] A fixture frame, wherein the fixture frame is provided with a mounting groove, and the mounting groove is used to mount the mounting column of the module;

[0006] The photoelectric sensing mechanism includes a photoelectric sensor, and the photoelectric sensor is configured to emit a sensing light beam, and the projection point of the sensing light beam is set at a positioning point of the mounting groove. When the sensing light beam senses the mounting column at the positioning point, the photoelectric sensor feeds back a correct positioning signal; when the sensing light beam does not sense the mounting column at the positioning point, the photoelectric sensor feeds back an abnormal positioning signal.

[0007] In one embodiment, the photoelectric sensing mechanism also includes a sensing marker, which is disposed on the mounting column. The photoelectric sensor is configured to emit a sensing light beam and receive reflected light of the sensing light beam, wherein the reflected light includes a first reflected light and a second reflected light, wherein the first reflected light is reflected when the sensing light beam is projected on the sensing marker, and the second reflected light is reflected when the sensing light beam is not projected on the sensing marker. When the photoelectric sensor receives the first reflected light, the photoelectric sensor feeds back a correct positioning signal, and when the photoelectric sensor receives the second reflected light, the photoelectric sensor feeds back an abnormal positioning signal.

[0008] In one embodiment, the photoelectric sensing mechanism further includes a beam positioning plate, the beam positioning plate is provided with a beam positioning hole, the beam positioning plate is connected to the jig frame and the beam positioning hole is horizontally opposite to the mounting groove, and the photoelectric sensor is arranged on a side of the beam positioning plate that is opposite to the mounting groove.

[0009] In one embodiment, the photoelectric sensing mechanism further includes a control system, wherein the control system is communicatively connected to the photoelectric sensor, and the control system is used to receive the correct positioning signal and the abnormal positioning signal.

[0010] In one embodiment, the photoelectric sensing mechanism also includes an operation panel, and the control system is communicatively connected to the operation panel. When the control system receives the correct positioning signal, the control system controls the operation panel to display correct positioning information. When the control system receives the abnormal positioning signal, the control system controls the operation panel to display abnormal positioning information.

[0011] In one embodiment, the module has a plate-like structure, the mounting column is arranged on the plate surface of the plate-like structure of the module, the jig frame includes a jig base and a plurality of jig pillars, the plurality of jig pillars are arranged on the jig base along the height direction, the plurality of jig pillars are provided with mounting grooves corresponding to each other, and the plurality of jig pillars support the plate surface of the plate-like structure of the module through the mounting grooves.

[0012] In one embodiment, the fixture base includes a plurality of base frame bars that are sequentially connected and enclosed, and the fixture pillars are arranged on the base frame bars.

[0013] In one embodiment, a plurality of the base frame bars are enclosed to form a rectangular frame, and the fixture pillars are disposed at the four corners of the rectangular frame.

[0014] In one embodiment, the fixture pillar further includes a mounting plate, the mounting plate is provided with a mounting hole and the mounting groove, and the mounting plate is connected to the fixture pillar through the mounting hole.

[0015] In one embodiment, the mounting groove includes a transverse positioning groove and a longitudinal positioning groove extending along the board surface direction of the mounting plate, the transverse positioning groove is perpendicular to the longitudinal positioning groove, one end of the longitudinal positioning groove is connected to the transverse positioning groove, and the other end of the longitudinal positioning groove is an open end.

[0016] In the technical solution of the present application, after the operator places the mounting column of the module in the mounting slot on the fixture frame, the projection point of the sensing light beam of the photoelectric sensor is located at the positioning point of the mounting slot. During the process of the operator slightly moving the mounting column, if the mounting column does not reach the positioning point of the mounting slot, the photoelectric sensor always feeds back an abnormal positioning signal, prompting the operator to continue adjusting the position until the operator moves the mounting column to the positioning point of the mounting slot. The photoelectric sensor senses the mounting column and feeds back a correct positioning signal, which not only ensures that the mounting column can be accurately placed at the positioning point of the mounting slot and ensures the installation accuracy of the module, but also assists the operator to quickly identify the abnormal placement status of the module and make adjustments, thereby improving the overall utilization rate of the photoelectric sensor positioning installation fixture.

[0027] See also Figures 1 to 3 , Figure 1 1 shows a schematic diagram of the structure of the photoelectric sensor positioning and installation fixture 1000. Figure 2 The schematic diagram of the placement structure of the module 300 of the photoelectric sensor positioning and installation fixture 1000 is shown. Figure 3 The schematic diagram of the structure of the photoelectric sensing mechanism 200 is shown. The present application proposes a photoelectric sensing positioning and installation fixture 1000, which is used for positioning and installing a module 300. The module 300 is provided with a mounting column 310. The photoelectric sensing positioning and installation fixture 1000 includes a fixture frame 100 and a photoelectric sensing mechanism 200. The fixture frame 100 is provided with a mounting groove 131, and the mounting groove 131 is used to install the mounting column 310 of the module 300. The photoelectric sensing mechanism 200 includes a photoelectric sensor 210, which is configured to emit a sensing light beam 211, and the projection point of the sensing light beam 211 is set at the positioning point of the mounting groove 131. When the sensing light beam 211 senses the mounting column 310 at the positioning point, the photoelectric sensor 210 feeds back a correct positioning signal. When the sensing light beam 211 does not sense the mounting column 310 at the positioning point, the photoelectric sensor 210 feeds back an abnormal positioning signal.

[0028] After the operator places the mounting post 310 of the module 300 in the mounting groove 131 on the fixture frame 100, the projection point of the sensing light beam 211 of the photoelectric sensor 210 is located at the positioning point of the mounting groove 131. When the operator slightly moves the mounting post 310, if the mounting post 310 does not reach the positioning point of the mounting groove 131, the photoelectric sensor 210 always feeds back a positioning abnormality signal, prompting the operator to continue adjusting the position until the operator moves the mounting post 310 to the positioning point of the mounting groove 131. The photoelectric sensor 210 senses the mounting post 310 and feeds back a positioning correct signal, which not only ensures that the mounting post 310 can be accurately placed at the positioning point of the mounting groove 131 and ensures the installation accuracy of the module 300, but also assists the operator to quickly identify the abnormal placement state of the module 300 and make adjustments, thereby improving the overall utilization rate of the photoelectric sensing positioning and mounting fixture 1000.

[0029] Exemplarily, the photoelectric sensing mechanism 200 also includes a sensing marker 220, which is disposed on the mounting column 310. The photoelectric sensor 210 is configured to emit a sensing light beam 211 and receive a reflected light 212 of the sensing light beam 211. The reflected light 212 includes a first reflected light and a second reflected light. The first reflected light is the sensing light beam 211 projected on the sensing marker 220 and reflected back. The second reflected light is the sensing light beam 211 not projected on the sensing marker 220 and reflected back. When the photoelectric sensor 210 receives the first reflected light, the photoelectric sensor 210 feeds back a correct positioning signal. When the photoelectric sensor 210 receives the second reflected light, the photoelectric sensor 210 feeds back an abnormal positioning signal.

[0030] Specifically, see Figures 1 to 3 The photoelectric sensor mechanism 200 further includes a beam positioning plate 230, which is provided with a beam positioning hole 231. The beam positioning plate 230 is connected to the fixture frame 100, and the beam positioning hole 231 is opposite to the mounting groove 131 in the horizontal direction. The photoelectric sensor 210 is arranged on the side of the beam positioning plate 230 that is opposite to the mounting groove 131. The beam positioning plate 230 is used to position the projection point of the sensing beam 211, and the beam positioning hole 231 is opposite to the mounting groove 131, so that the sensing beam 211 is projected on the positioning point through the beam positioning hole 231.

[0031] Furthermore, the photoelectric sensing mechanism 200 further includes a control system, which is communicatively connected to the photoelectric sensor 210, and is used to receive a correct positioning signal and an abnormal positioning signal. Exemplarily, the control system is a PLC control system.

[0032] Furthermore, the photoelectric sensing mechanism 200 also includes an operation panel, and the control system is communicatively connected to the operation panel. When the control system receives a correct positioning signal, the control system controls the operation panel to display correct positioning information. When the control system receives an abnormal positioning signal, the control system controls the operation panel to display abnormal positioning information.

[0033] Specifically, see Figures 1 to 3 The module 300 has a plate-like structure, and the mounting column 310 is arranged on the plate surface of the plate-like structure of the module 300. The fixture frame 100 includes a fixture base 110 and a plurality of fixture pillars 120. The plurality of fixture pillars 120 are arranged on the fixture base 110 along the height direction. The plurality of fixture pillars 120 are provided with mounting grooves 131 corresponding to each other. The plurality of fixture pillars 120 support the plate surface of the plate-like structure of the module 300 through the mounting grooves 131.

[0034] The fixture base 110 includes a plurality of base frame bars 111 that are connected and enclosed in sequence, and the fixture pillars 120 are arranged on the base frame bars 111. The plurality of base frame bars 111 can be enclosed in other shapes such as polygons and rectangles, which are not specifically limited here. By way of example, the plurality of base frame bars 111 are enclosed to form a rectangular frame, and the four corners of the rectangular frame are provided with fixture pillars 120. The two fixture pillars 120 on the same side can position and install a module 300, and a single photoelectric sensor positioning and installation fixture 1000 can install two modules 300 at the same time, thereby improving utilization. The cross-section of the fixture pillar 120 can be set in other shapes such as circular and square, which are not specifically limited here. By way of example, the cross-section of the fixture pillar 120 is set in a square. The jig frame 100 further includes a reinforcement 140 , which is a triangular column structure. The reinforcement 140 is disposed at the angle between adjacent base frame bars 111 and at the angle between the connected jig pillars 120 and the base frame bars 111 to enhance the overall structural strength of the jig frame 100 .

[0035] Specifically, see Figures 1 to 3 The jig pillar 120 also includes a mounting plate 130, which is provided with a mounting hole and a mounting groove 131, and the mounting plate 130 is connected to the jig pillar 120 through the mounting hole. Exemplarily, the mounting plate 130 includes an L-shaped bending part, and the mounting hole and the mounting groove 131 are respectively arranged on the two ends of the L-shaped bending part. The mounting groove 131 includes a transverse positioning groove 1311 and a longitudinal positioning groove 1312 extending along the plate surface direction of the mounting plate 130, the transverse positioning groove 1311 is perpendicular to the longitudinal positioning groove 1312, one end of the longitudinal positioning groove 1312 is connected to the transverse positioning groove 1311, and the other end of the longitudinal positioning groove 1312 is an open end. The operator places the mounting column 310 in the mounting groove 131 from the open end of the longitudinal positioning groove 1312 and adjusts the position until the mounting column 310 is placed at the positioning point.

[0036] Furthermore, the photoelectric sensor positioning and installation fixture 1000 also includes a suction cup loading mechanism, which is used to absorb and move the module 300 to replace manual positioning operations of the module 300. In conjunction with the photoelectric sensor mechanism 200, it can effectively improve positioning accuracy and work efficiency.

[0037] In the technical solution of the present application, after the operator places the mounting column 310 of the module 300 in the mounting groove 131 on the fixture frame 100, the projection point of the sensing light beam 211 of the photoelectric sensor 210 is located at the positioning point of the mounting groove 131. When the operator slightly moves the mounting column 310, if the mounting column 310 does not reach the positioning point of the mounting groove 131, the photoelectric sensor 210 always feeds back a positioning abnormality signal, prompting the operator to continue adjusting the position until the operator moves the mounting column 310 to the positioning point of the mounting groove 131. The photoelectric sensor 210 senses the mounting column 310 and feeds back a positioning correct signal, which not only ensures that the mounting column 310 can be accurately placed at the positioning point of the mounting groove 131 and ensures the installation accuracy of the module 300, but also assists the operator to quickly identify the abnormal placement state of the module 300 and make adjustments, thereby improving the overall utilization rate of the photoelectric sensing positioning and mounting fixture 1000.
