Description

Technical Field

[0001] The invention relates to the technical field of thin and small material feeding equipment, and in particular to a continuous feeding mechanism and a visual inspection robot. Background Art

[0002] In the process of processing, assembling and conveying semi-finished electronic materials, it is very necessary to make full use of automated conveyor lines; conveyor lines generally consist of the three most basic parts of automatic loading, namely, feeding conveyor lines, visual inspection mechanisms and loading conveyor lines. In automated processing and assembly production lines, the full-process device that can automatically complete the supply and loading of materials to processing or assembly machinery is called an automatic loading conveyor line. During the processing of equipment, there is a common situation of uneven incoming materials in the conveyor line. When the conveyor line is intermittently fed, there will be gaps in the materials on the conveyor line, which is not conducive to improving the loading efficiency. In order to eliminate the gaps in materials on the conveyor line and improve the loading efficiency, we often use the following method: using two-stage conveyor lines such as loading conveyor lines and feeding conveyor lines, connecting the front and rear ends of the conveyor lines, setting the loading conveyor line speed to be lower than the feeding conveyor line speed, and the materials on the feeding conveyor line are squeezed due to the material obstruction on the front end of the loading conveyor line to eliminate the loading gaps and realize continuous loading; if the feeding speed is too fast, it is easy to push too tight and too much, so it is necessary to adjust the loading speed at any time, and the running speed of the loading conveyor line is affected by the feeding conveyor line. At the same time, the two-stage conveyor line also has disadvantages such as occupying a large space and requiring a large installation space. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a continuous feeding mechanism and a visual inspection robot, which can solve the problem that when the continuous feeding mechanism feeds intermittently, there will be gaps in feeding; the running speed of the feeding conveyor line is affected by the speed of the feeding conveyor line. At the same time, the conveyor line is very long and occupies a large space, requiring a large installation space.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a continuous feeding mechanism, including a loading conveying mechanism, a feeding conveying mechanism, and a magnetic suction device; the feeding conveying mechanism is arranged below the loading conveying mechanism, and there is a space between the loading conveying mechanism and the feeding conveying mechanism for allowing materials to pass;

[0009] Furthermore, the space between the loading conveying mechanism and the feeding conveying mechanism for allowing materials to pass through is greater than the height of one material and less than the height of two materials.

[0010] Furthermore, the feeding and conveying mechanism includes a motor, a reduction gear box, a driving wheel, a follower wheel, a second conveyor belt, and a base frame; the motor is connected to the reduction gear box, installed on the base frame, and drives the driving wheel to rotate through the reduction gear box; the second conveyor belt is installed on the driving wheel and the follower wheel; the material is transmitted to one end of the feeding and conveying mechanism through the second conveyor belt.

DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] The present invention will be further described with reference to the accompanying drawings. Figure 1As shown, a continuous feeding mechanism and a visual inspection robot structure are as follows:

[0030] A continuous feeding mechanism is composed of a feeding conveying mechanism, a loading conveying mechanism, and a loading platform;

[0031] The feeding conveying mechanism is installed on the base frame by a motor, a reduction gear box, a driving wheel, a driven wheel, and a second belt. The motor is connected to the reduction gear box to drive the driving wheel, and the driving wheel is connected to the driven wheel through the second belt. The second belt transports the material to the feeding conveying mechanism.

[0032] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the structure of a continuous feeding mechanism and a visual inspection robot feeding and conveying mechanism is as follows:

[0033] The feeding conveying mechanism consists of a driving device, a transmission wheel, a magnetic strip, a first belt, a passive wheel, a tensioning assembly, and a support frame, which are installed on the main board of the conveyor line. The driving device drives the transmission wheel, and the transmission wheel is connected to the passive wheel through the first belt. The magnetic strip is arranged on the inner side of the first belt and extends from the transmission wheel to the passive wheel. There is no magnetic strip above the feeding platform. The magnetic force of the magnetic strip absorbs the material on the second belt to the first belt through the first belt. When the material on the first belt enters the feeding platform, the material is separated from the magnetic force of the magnetic strip and falls to the feeding platform. The length of the magnetic strip is based on the absorption of at least one material, and can also be extended to absorb multiple materials. A slide groove is also arranged on the main board of the conveyor line. The tensioning assembly is connected to the passive wheel and arranged in the slide groove. The distance between the transmission wheel and the passive wheel can be adjusted.

[0034] like Figure 6 As shown, a tensioning assembly structure of a continuous feeding mechanism and a visual inspection robot is as follows:

[0035] The tensioning assembly is arranged on the passive wheel to adjust the distance between the driven wheel and the driving wheel. The tensioning assembly is composed of an adjustment plate, a fixed plate, an adjustment screw, and a fixed nut. A slide groove is arranged at one end of the conveyor main board near the driven wheel. The adjustment plate is arranged in the slide groove. One end of the adjustment plate is connected to the driven wheel. The adjustment screw passes through the fixed nut, the fixed plate, and the other end of the adjustment plate is threadedly connected in sequence, so that the adjustment plate moves in the slide groove, thereby adjusting the tightness of the first belt.

[0036] The loading platform receives the materials dropped from the first belt and transports the materials to the next process in sequence.

[0037] like Figure 7 A schematic diagram of a continuous feeding mechanism and a visual inspection robot material feeding is shown as follows:

[0038] The second belt of the feeding conveyor mechanism transports the material to the first belt of the loading conveyor mechanism. The visual inspection mechanism (not shown in the figure) is separately arranged above the second belt of the feeding conveyor mechanism to detect the quality of the material and determine whether the feed is qualified. At the same time, unqualified products can also be processed.

[0039] like Figure 8 , Fig. 9 , Fig.10 As shown, a continuous feeding mechanism and a visual inspection robot structure material flow state is as follows:

[0040] When the material which is magnetic or can be magnetized is sequentially conveyed by the second belt of the feeding conveyor mechanism, when the first material reaches the lower end surface of the first belt of the feeding conveyor mechanism, since a magnetic strip is installed on the inner side of the first belt of the feeding conveyor mechanism, the magnetic force of the magnetic strip absorbs and fixes the first material on the first belt of the feeding conveyor mechanism through the first belt, and the first material moves toward the upper feeding platform along with the first belt of the feeding conveyor mechanism.

[0041] Since the speed of the feeding conveyor mechanism is greater than that of the loading conveyor mechanism, the first material adsorbed on the first belt decelerates, and the second material, the third material, and the fourth material on the second belt gradually catch up with the first material on the first belt. Since the space between the loading conveyor mechanism and the feeding conveyor mechanism for allowing materials to pass through is greater than the height of one material and less than the height of two materials, the first material on the first belt blocks the second material on the second belt, and the second material gradually approaches the first material until it fits together, thereby eliminating the gap between the first material and the second material.

[0042] Since the first material blocks the second material, the second material slips on the second belt, and the third material and the fourth material gradually approach the second material until they fit together, thereby eliminating the gap between the second material and the third material; similarly, the gap between the third material and the fourth material is eliminated in turn.

[0043] The first belt of the feeding conveyor mechanism continues to move toward the feeding platform, and the first material is separated from the magnetic force range of the magnetic stripe and falls off from the first belt to the feeding platform to complete the feeding. At the same time, when the first material is separated from the magnetic force range of the magnetic stripe, the second material enters the magnetic force range of the original first material magnetic stripe and moves toward the feeding platform with the first belt of the feeding conveyor mechanism until it falls off to the feeding platform and waits for the next feeding. All materials are positioned, blocked, and fallen off in sequence according to the speed of the feeding conveyor mechanism to complete the feeding action.

[0044] The present invention provides a continuous feeding mechanism and a visual inspection robot that adopts a feeding conveying mechanism, a loading conveying mechanism and a positioning mechanism. When gaps appear in the materials on the feeding conveying line of the feeding conveying mechanism, the gaps between the materials are eliminated to achieve continuous feeding, thereby improving the feeding efficiency. The speed of the loading conveying mechanism is controlled to be equal to the feeding speed. The running speed of the loading conveying mechanism is not affected by the incoming material speed of the feeding conveying mechanism. The loading conveying mechanism and the feeding conveying mechanism are overlapped to reduce the total length of the equipment, thereby saving the space occupied by the equipment.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
