When the side frame maintains a vertical posture while sliding along the first guide rods, the overall structure of the detection equipment is relatively simple and the preparation cost is relatively low.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0046] A side frame detection device provided by the embodiment of the utility model is used for detecting the side frame 100, referring to Figure 4 The side frame 100 includes a side edge 110 and two top edges 120 (refer to Figure 4 ), one end of a top edge 120 is connected to one end of a side edge 110, one end of another top edge 120 is connected to the other end of the side edge 110, and the side frame 100 is arranged in a U shape as a whole; wherein the connection position between the two side edges 110 and one top edge 120 forms a corner bending portion 130.

[0047] Among them, see Figures 1 to 3 The detection device includes a feeding mechanism 200, a machine table 300, a conveying mechanism 400 and a detection mechanism 500, wherein the feeding mechanism 200 is arranged on the machine table 300 along the Y axis, and the feeding mechanism 200 includes a mounting frame 220 and a conveyor belt 210 and two first guide rods 230 arranged on the mounting frame 200, wherein the conveyor belt 221 has a stop position, and the first guide rod 230 is located above the conveyor belt 210 along the conveying direction of the conveyor belt 210, and one first guide rod 230 is used to penetrate the inner side of one corner bending portion 130, and the other first guide rod 230 is used to penetrate the inner side of the other corner bending portion 130, so that the side frame 100 is vertically (that is, the standing direction of the side frame 100) across the two first guide rods 230 and abuts against the conveyor belt 210, and the conveyor belt 210 is used to transport the side frame 100 to the stop position of the conveyor belt 210 (refer to Figure 4 ), whereby the two first guide rods 230 vertically support the side frame 100, and the surface of the conveyor belt 210 is used to fit the end of the side frame 100. More specifically, the side frame 100 is vertically placed on the two first guide rods 230, and the ends of the two top edges 120 of the side frame 100 just fit the surface of the conveyor belt 210. The transport mechanism 400 and the detection mechanism 500 are arranged on the machine platform 300, and the transport mechanism 400 is used to transport the side frame 100 conveyed by the feeding mechanism 200 to the detection mechanism 500, and the detection mechanism 500 is used to detect defects of the side frame 100.

[0048] Specifically, in the feeding stage, the side frame 100 is vertically placed on the two first guide rods 230 in sequence, one first guide rod 230 is pressed against the inner side of one corner bend 130, or against the inner side of the connection between one top edge 120 and the side edge 110; the other first guide rod 230 is pressed against the inner side of another corner bend 130, or against the inner side of the connection between another top edge 120 and the side edge 110, and the ends of the two top edges 120 are attached to the conveyor belt 210 of the feeding mechanism 200. It can be seen that the side frame 100 is vertically placed on the conveyor belt 210 using the two first guide rods 230. Therefore, during the movement of the conveyor belt 210, the conveyor belt 210 uses the friction between the side frame 100 to drive the side frame 100 to move along the first guide rods 230 toward the stop position of the feeding mechanism 200, and is blocked when moving to the stop position, thereby maintaining the stop position. During the inspection phase, the transport mechanism 400 transports the side frame 100 at the material stopping position to the inspection mechanism 500 , and the inspection mechanism 500 performs defect inspection on the side frame 100 .

[0049] It can be understood that the side frames 100 are neatly transported vertically on the feeding mechanism 200, and each time the transport mechanism 400 takes the side frame 100 from the stop position of the feeding mechanism 200, the conveyor belt 210 transports the next side frame 100 to the stop position of the feeding mechanism 200. In this way, the transport mechanism 400 can quickly transport the vertical side frames 100 from the stop position of the feeding mechanism 200 in a uniform posture each time, and the transport mechanism 400 does not need a more complicated motion stroke and constantly changing motion postures, which ensures the transport efficiency of the transport mechanism 400, has a simpler structure, and has a lower preparation cost. Moreover, the transport mechanism 400 moves to the same position each time to pick up the side frame 100, and the control system does not need to set up a more complicated control program to control the transport mechanism 400 to transport the side frame 100 at the stop position, and the transport mechanism 400 does not need to set up a more complicated drive mechanism to execute the picking up of the side frame 100.

[0050] Moreover, the present application utilizes two first guide rods 230 to vertically support the side frame 100, and the friction between the first guide rods 230 and the side frame 100 is relatively small, so the conveyor belt 210 can utilize the friction between the side frame 100 and the conveyor belt 210 to drive the side frame 100 to slide along the first guide rods 230, thereby conveying the side frame 100 to the material stopping position. Furthermore, the friction between the first guide rods 230 and the side frame 100 is relatively small, which can prevent the side frame 100 from being easily damaged by friction during the sliding process.

[0051] See also Figure 2The mounting frame 220 includes a front baffle frame 221 and a rear baffle frame 222, wherein, in the conveying direction of the conveyor belt 210, the front baffle frame 221 is arranged at the input end of the conveyor belt 210, and the rear baffle frame 222 is arranged at the output end of the conveyor belt 210. More specifically, both are arranged at both ends of the conveyor belt 210 in a roughly U-shaped manner. One end of the first guide rod 230 is connected to the front baffle frame 221, and the other end is connected to the rear baffle frame 222. When the conveyor belt 210 drives the side frame 100 to slide along the first guide rod 230, when the side frame 100 moves to the stop position of the conveyor belt 210, the rear baffle frame 222 just blocks the side frame 100 from continuing to move forward, thereby, the side frame 100 is just located at the stop position under the blocking of the rear baffle frame 222.

[0052] In some embodiments, reference Figures 2 to 4 The detection device further includes a limit rod 250, and the limit rod 250 is provided with a mounting frame 220 of the feeding mechanism 200 along the conveying direction of the conveyor belt 210, that is, one end of the limit rod 250 is connected to the front stop frame 221, and the other end is connected to the rear stop frame 222. The first guide rod 230 and the limit rod 250 are provided in equal numbers and are matched one by one. Specifically, the limit rod 250 is arranged in parallel on one side of the first guide rod 230, and the two are arranged at intervals, that is, the two first positioning rods 230 are located between the two limit rods 250, so that a guide gap is defined between the first guide rod 230 and the limit rod 250, and the guide gap is extended along the conveying direction of the conveyor belt 210. Therefore, when the side frame 100 is placed on the conveyor belt 210, the two top edges 120 of the side frame are respectively placed in the guide gap between the first guide rod 230 and the limit rod 250. More specifically, the limit rod 250 is used to limit the top edge 120 from being away from one side of the first guide rod 230.

[0053] Of course, the number of limit rods 250 may also be less than the number of first guide rods 230. For example, instead of setting two limit rods 250 between two adjacent guide rod groups, one limit rod 250 is set between two adjacent guide rod groups. Thus, the limit rod 250 is simultaneously supported against the top edges 120 of the two side frames 100.

[0054] It can be understood that when the side frame 100 is placed on the two first guide rods 230, limit rods 250 are respectively provided on both sides of the frame 10, and the limit rods 250 further limit the position of the side frame 100 on the basis of the first guide rods 230. In this way, the side frame 100 can be stably placed on the upper side of the two first guide rods 230 to avoid tilting of the side frame 100.

[0055] Furthermore, the detection device further includes a second guide rod 240, which is arranged on the mounting frame 220 of the feeding mechanism 200 along the conveying direction of the conveyor belt 210. The second guide rod 240 is located between the two first guide rods 230, one end of which is connected to the front stop frame 221, and the other end of which is connected to the rear stop frame 222. When the side frame 100 is placed on the two first guide rods 230, the second guide rod 240 just supports the side edge 110 of the side frame 100. Therefore, on the basis of the two first guide rods 230, the side edge 110 of the side frame 100 is further supported by the second guide rod 240, thereby further limiting the position of the side frame 100 to prevent the side frame 100 from tilting.

[0056] In some embodiments, reference Figure 1 and Figure 5 The detection mechanism 500 includes a transmission module 510 and a detection module 520, wherein the transmission module 510 is arranged on the machine 300 along the X-axis, the output end of the feeding mechanism 200 is arranged toward the side of the input end of the transmission module 510, and the conveying mechanism 400 is arranged on the machine 300 along the Y-axis, and is connected with the feeding mechanism 200 and the transmission module 510, thereby, the conveying mechanism 400 conveys the side frame 100 from the feeding mechanism 200 to the transmission module 510 along the Y-axis. The detection module 520 is arranged on the machine 300 and is located on the conveying track of the transmission module 510, thereby, after receiving the side frame 100 conveyed by the conveying mechanism 400, the transmission module 510 conveys the side frame 100 to the corresponding position of the detection module 520, and the detection module 520 inspects the side frame 100. After the inspection of the side frame 100 is completed, the conveying module 510 conveys the side frame 100 to a material stopping position of the conveying module 510 .

[0057] In some embodiments, the detection module 520 includes a front detection module 521 and a back detection module 522 respectively arranged on both sides of the transmission module 510. The front detection module 521 and the back detection module 522 are both arranged in a ring shape and are vertically fixed on the machine 300. The transmission module 510 is located between the front detection module 521 and the back detection module 522. More specifically, the front detection module 521 and the back detection module 522 are located on the left and right sides of the transmission module 510.

[0058] Among them, along the transmission direction of the transmission module 510, the front detection module 521 and the back detection module 522 are arranged opposite to each other, or, along the transmission direction of the transmission module 510, the front detection module 521 and the back detection module 522 are partially or completely staggered, depending on actual needs.

[0059] Specifically, the transmission module 510 transmits the side frame 100 to a position opposite to the front detection module 521, the front detection module 521 takes a photo of the front of the side frame 100, and transmits it to the terminal for detection; and, the transmission module 510 transmits the side frame 100 to a position opposite to the back detection module 522, the back detection module 522 takes a photo of the back of the side frame 100, and transmits it to the terminal for detection.

[0060] Furthermore, the detection mechanism 500 further includes a control module, which is electrically connected to the detection module 520, more specifically, the control module is electrically connected to the front detection module 521 and the back detection module 522, and the control module controls the front detection module 521 and the back detection module 522 to successively shoot at least twice the same side frame 100. It can be understood that the front detection module 521 and the back detection module 522 successively shoot the side frame 100 twice, and the two images are spliced ​​in the software, and the software automatically calculates the outer contour, the joint line contour and the width dimension of the side frame 100, so as to detect the size defects of the side frame 100.

[0061] In some embodiments, reference Figure 5 and Figure 6 The detection device includes two conveying modules 510 arranged in parallel, each conveying module 510 includes a conveyor and a fixture assembly 512, wherein the conveyor is arranged on the machine 100 along the X-axis, and the fixture assembly 512 is arranged on the conveying part of the conveyor, and the fixture assembly 512 is used for vertical loading of the side frame 100. The fixture assemblies 512 of the two conveying modules 510 are located on the same conveying surface, more specifically, the two fixture assemblies 512 are located in the same vertical plane extending along the conveying direction. At least one fixture assembly 512 can be adjusted up and down to stagger with another fixture assembly 512. For example, a lifting module 511 is arranged on the conveying part of each conveyor, and the lifting module 511 can be a cylinder, a screw lifting structure, etc. The fixture assembly 512 is assembled and connected to the lifting module 511, and the lifting module 511 lifts and adjusts the fixture assembly 512, thereby, the fixture assemblies 512 of the two conveying modules 510 can be lifted and lowered.

[0062] Specifically, after the left jig assembly 512 receives the side frame 100, the jig assembly 512 moves rightward toward the stop position, and at the same time, after the right jig assembly 512 passes out of the side frame 100, the jig assembly 512 moves leftward toward the loading position. When the two jig assemblies 512 pass through the intersection position, the lifting module 511 corresponding to one jig assembly 512 lowers the height of the jig assembly 512, and the two jig assemblies 512 are staggered in height and do not interfere with each other, so that the two jig assemblies 512 can move back and forth between the loading position, the detection position (the position of the detection module corresponding to the transmission track) and the stop position. It can be understood that the two jig assemblies 512 are located in the same vertical plane along the conveying direction. With this arrangement, the two jig assemblies 512 reciprocate between the same loading position, detection position and stop position. The two jig assemblies 512 can complete the loading, detection and unloading of the side frame 100. The two jig assemblies 512 ensure the detection efficiency of the detection module 520.

[0063] In some embodiments, reference Figure 7 and Figure 8 The detection mechanism 500 further includes a fixture assembly 512 disposed on the conveying module 510, and the fixture assembly 512 is used to load the side frame 100. Specifically, the fixture assembly 512 includes a carrier 513, a fixed clamp 515, a movable clamp 516 and an elastic reset member 514, wherein the carrier 513 is fixedly disposed on the conveying portion of the conveying module 510, more specifically, the carrier 513 is fixed on the lifting module 511. The fixed clamp 515 is vertically fixedly disposed on the carrier 513, and the movable clamp 516 is vertically located on one side of the fixed clamp 515, and is slidably disposed on the carrier 513 away from or close to it. The elastic reset member 514 is connected to the carrier 513 and the movable clamp 516. The elastic reset member 514 resets the movable clamp 516 toward the fixed clamp 515. Thus, under the action of the elastic reset member 514, the side frame 100 is clamped between the fixed clamp 515 and the movable clamp 516 and maintains a vertical placement posture.

[0064] Further, refer to Figure 5 and Figure 7 The detection mechanism 500 further includes two unlocking modules 530, which are cylinders or other driving structures arranged on the machine 300. One unlocking module 530 is arranged at the loading position of the conveying module 510. When the fixture assembly 512 is at the loading position of the conveying module 510, the unlocking module 530 pushes the movable clamp 516 to move away from the fixed clamp 515. The other unlocking module 530 is arranged at the stopping position of the conveying module 510. When the fixture assembly 512 is at the stopping position of the conveying module 510, the unlocking module 530 pushes the movable clamp 516 to move away from the fixed clamp 515.

[0065] Specifically, when the jig assembly 512 moves to the loading position, the corresponding unlocking module 530 pushes the movable clamp 516 to move away from the fixed clamp 515, and the fixed clamp 515 and the movable clamp 516 remain in an open state, so that the transport mechanism 400 can vertically place the captured side frame 100 on the carrier 513 and between the fixed clamp 515 and the movable clamp 516. At this time, the corresponding unlocking module 530 releases the force on the movable clamp 516, and the movable clamp 516 moves toward the fixed clamp 515 under the action of the elastic reset member 514, so that the side frame 100 is clamped between the fixed clamp 515 and the movable clamp 516. When the jig assembly 512 carries the side frame 100 to the material stopping position, the corresponding unlocking module 530 pushes the movable clamp 516 to move away from the fixed clamp 515, and the movable clamp 516 releases the clamping force on the side frame 100. Therefore, the sorting mechanism 700 of the next node can grab the side frame 100 on the jig assembly 512.

[0066] It is understandable that the jig assembly 512 does not need to be equipped with a power source such as a cylinder to drive the movable clamp 516 to move toward or away from the fixed clamp 515. With this arrangement, the jig assembly 512 occupies a small space and will not interfere when passing through the narrow space between the front detection module 521 and the back detection module 522.

[0067] Further, refer to Figure 8 The edges of the fixed clamp 515 and the movable clamp 516 are both provided with protrusions 517, and one or more protrusions 517 may be provided, for example, three protrusions 517 are provided. When the fixed clamp 515 and the movable clamp 516 clamp the side frame 100, two protrusions 517 are respectively abutted against the two top edges 120 of the side frame 100, and the other protrusion 517 is abutted against the side edge 110 of the side frame 100. In this way, when the fixed clamp 515 and the movable clamp 516 clamp the side frame 100, the shielding area of ​​the front and back of the side frame 100 is small, thereby ensuring that the detection mechanism 500 can accurately detect the defects of the side frame 100.

[0068] In some embodiments, reference Figure 1 and Fig. 9 The detection mechanism 500 further includes a scanning module 540, which includes an adjustment bracket 541 and a barcode scanner 542, wherein the adjustment bracket 541 is fixedly mounted on the machine platform 300, and the barcode scanner 520 is assembled and connected to the adjustment bracket 541 and is located on the transmission path of the transmission module 510. Specifically, when the transmission module 510 transmits the side frame 100 to the position corresponding to the barcode scanner 520, the barcode scanner 520 scans the code on the side frame 100, thereby obtaining the information of the side frame 100, and the software can subsequently record the detection information of the side frame 100.

[0069] Among them, the adjustment bracket 541 can be raised and lowered to adjust the height of the barcode scanner 520, and can be rotated around the Y-axis to adjust the angle of the barcode scanner 520. With this setting, the barcode scanner 520 can be adjusted to a suitable position and angle, and the side frame 100 can scan the code on the side frame 100 when passing the position corresponding to the barcode scanner 520.

[0070] Further, refer to Figure 1 and Fig.10 The detection device further includes a feeding mechanism 600 and a sorting mechanism 700, wherein the feeding mechanism 600 is arranged on the machine 300 along the X-axis and is located on one side of the conveying module 510. The feeding mechanism 600 has a plurality of output channels 610, which are a detection NG channel 611, a code scanning NG channel 612 and a qualified channel 613. The sorting mechanism 700 is arranged on the machine 300 along the Y-axis, and the sorting mechanism 700 is connected to the conveying module 510 and the feeding mechanism 600, and is electrically connected to the code scanning module 540 and the detection module 520. The sorting mechanism 700 sorts the edge frames 100 to different output channels 610 based on the detection results of the detection module 520 and the scanning results of the scanning module 540; for example, the sorting mechanism 700 moves the edge frames 100 that have passed the code scanning and detection to the qualified channel 613, moves the edge frames 100 that have failed the code scanning to the code scanning NG channel 612, and moves the edge frames 100 that have failed the detection to the detection NG channel 611.

[0071] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
