The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0026] First embodiment:

Figure 2 This is a schematic diagram of the installation structure of the second supporting rubber roller. Figure 3 is a schematic diagram of the installation structure of the first support seat and the second support seat, Figure 4 It is a schematic diagram of the structure of the through hole.

[0028] The present invention provides a small gap plane support wheel support mechanism and installation method, including a belt 101, a transmission assembly 102, a vacuum platform 103 and a support assembly 105, wherein the support assembly 105 includes a support mounting plate 106, a first support seat 107, a second support seat 108 and an elastic member 109, wherein the first support seat 107 includes a first seat body 110 and a first support rubber roller 111, the second support seat 108 includes a second seat body 112 and a second support rubber roller 113, the elastic member 109 includes a support spring 114 and a support mounting block 115, the transmission assembly 102 includes a driving wheel 116, driven wheel 117 and tensioning and correcting wheel 118 support the bottom of the inspected target through the first support seat 107 and the second support seat 108 to prevent the inspected target from affecting the visual imaging effect due to its own gravity or warping. At the same time, through the elasticity of the elastic member 109, the second support seat 108 can move up and down to facilitate the passage of the inspected target and avoid jamming due to the appearance difference of the inspected target itself. It can be understood that the above scheme can be used to prevent the inspected target from jamming, and can also be used to improve the transmission effect of the belt 101.

[0029] According to this specific embodiment, the belt 101 is sleeved on the transmission component 102, the transmission component 102 is used to drive the belt 101 to rotate, the vacuum platform 103 is arranged on the inner side of the belt 101, and the belt 101 is provided with a through hole 104; the transmission component 102 is used to drive the belt 101 to rotate, and then transport the detected target thereon, and the belt 101 is evenly provided with a plurality of through holes 104, and the vacuum platform 103 adsorbs the detected target through the through holes 104 on the belt 101.

[0030] Among them, the support mounting plate 106 is arranged below the belt 101, the first support seat 107 is connected to the support mounting plate 106 and is located on the side of the support mounting plate 106 close to the belt 101, the second support seat 108 is connected to the support mounting plate 106 and is located on the side of the support mounting plate 106 close to the belt 101, the elastic member 109 is arranged on the support mounting plate 106, and provides elastic force to the second support seat 108, so that the second support seat 108 contacts the surface of the belt 101; there are two first support seats 107, which are located in the middle of the support mounting plate 106, and there are two second support seats 108, which are located on the front and rear sides of the support mounting plate 106. The elastic member 109 is used to provide elasticity to the second support seat 108 so that the second support seat 108 can move up and down; when in use, the inspected target is transported to the inspection surface by the belt 101 and is adsorbed by the vacuum platform 103. The first support seat 107 and the second support seat 108 provide a supporting force below the inspected target to ensure the flatness of the inspected target, while also effectively avoiding the deformation of the inspected target due to its own gravity, and then the imaging surface changes, causing blurred imaging; at the same time, through the elasticity of the elastic member 109, the second support seat 108 can move up and down, so that when the inspected target passes above the support assembly 105, it can avoid the inspected target from getting stuck and affecting the visual imaging.

[0031] Secondly, the first seat body 110 is fixedly connected to the support mounting plate 106 and is arranged on the support mounting plate 106; the first support rubber roller 111 is rotatably connected to the first seat body 110 and is arranged on the first seat body 110; the first support rubber roller 111 is divided into five parts, and its two ends are rotatably mounted on the first seat body 110 through bearings. Through the rotation of the first support rubber roller 111, the friction between it and the inspected object is reduced, thereby avoiding the inspected object from getting stuck.

[0032] At the same time, the second seat body 112 is fixedly connected to the support mounting plate 106 and is arranged on the support mounting plate 106; the second support rubber roller 113 is connected to the second seat body 112 and is arranged on the second seat body 112; the second support rubber roller 113 is divided into two parts, and the two ends of the second support rubber roller 113 rotate through bearings, and the bearings slide up and down on the second seat body 112 through the bearing seats, so that the second support rubber roller 113 can change in height.

[0033] In addition, the support mounting block 115 is fixedly connected to the support mounting plate 106 and is located at the bottom of the support mounting plate 106; the two ends of the support spring 114 are respectively connected to the support mounting block 115 and the second support rubber roller 113; the bottom of the support spring 114 is supported by the support mounting block 115, and at the same time, the support spring 114 provides elasticity to the second support rubber roller 113, so that the second support rubber roller 113 can abut against the belt 101, and at the same time, it can shrink downward when the inspected object passes by, so that the inspected object can pass.

[0034] Then, the driving wheel 116 is movably connected to the belt 101 and is located on the inner side of the belt 101; the driven wheel 117 is movably connected to the belt 101 and is located on the inner side of the belt 101; the driving wheel 116 and the driven wheel 117 are set at the same height and are located on the same horizontal plane. The driving wheel 116 is connected to the output end of an external motor (not shown in the figure), and the belt 101 is driven to rotate by the rotation of the driving wheel 116, thereby transmitting the inspected target.

[0035] Finally, the tensioning and deflection-correcting wheel 118 is movably connected to the belt 101 and is located on the inner side of the belt 101; the belt 101 is tensioned and deflected by the tensioning and deflection-correcting wheel 118 to ensure the stability of the belt 101 during the process of transporting the inspected target.

[0036] When the small gap flat support wheel support mechanism of the present embodiment is used, the inspected target is transmitted by the belt 101. After the inspected target is transmitted to the support assembly 105, the inspected target is adsorbed by the vacuum platform 103. At the same time, the support assembly 105 provides support force for the bottom of the inspected target to ensure the flatness of the inspected target. At the same time, since the inspection area is too wide, when the inspected target passes through the inspection area, its deformed part will hit the second supporting rubber roller 113 below when it resets, causing rollover or transportation jam. At this time, the elasticity of the support spring 114 allows the second supporting rubber roller 113 to move downward to avoid jamming of the inspected target. The second supporting rubber roller 113 at the entrance of the inspection area is provided with two parts, while the first supporting rubber roller 111 in the inspection area is provided with five parts. This structure has good transmission stability and good rigidity, and the entire mechanism effectively ensures smooth and accurate transmission.

[0037] The small clearance plane support wheel support mechanism of the present invention has the following beneficial effects:

[0038] 1) The vacuum platform adsorption device with support wheel belt drive of the present invention is simpler, more compact and saves space;

[0039] 2) The present invention makes up for the problem that the traditional conveying structure may cause the plate to get stuck during the inspection because the inspected object is uneven or falls;

[0040] 3) The belt-driven vacuum platform adsorption device with a support wheel and the plane support wheel support mechanism of the present invention greatly improve the passability and stability of the detected target during the visual imaging process;

[0041] 4) The rigidity and service life of the support rollers on the planar support wheel support mechanism of the present invention are improved, and the problems of jamming and blurred imaging caused by deformation of the inspected object itself are effectively solved, thereby increasing the overall life and practicality of the mechanism.

[0042] Based on the above beneficial effects, the core market competitiveness of machine vision equipment has been greatly improved.
