Description

Technical Field

[0002] For sheet materials, such as circuit boards and trays, when both the upper and lower surfaces of the materials need to be inspected, the materials need to be turned over between the upper and lower surface inspection processes. Traditional automation equipment often uses a manipulator to absorb or clamp the material and directly drive it to turn over. For some smaller materials, the manipulator can quickly complete the turning action; but for some materials with heavy weight and large volume, the manipulator needs to slow down the turning action to prevent the centrifugal force on the material from being too large, causing wear and even deformation at the contact point with the manipulator.

[0003] At the same time, for the loading and unloading processes, it is necessary to ensure that the materials can be placed in the designated position accurately and efficiently. For the loading and unloading processes of sheet materials, the sheet materials must be stored in the material box so that the subsequent materials can be transferred to the next process.

Similarly, by driving the push rod through the push cylinder, the materials on the conveyor line can be pushed into the empty material box in sequence, and after the material box is full, it is stored in the full box feeding position in sequence, so that the subsequent materials can be transferred to the next process.

[0032] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances. Embodiment 1

[0034] like Figure 1-Figure 6 As shown, a flipping mechanism for material detection includes multiple groups of conveyor lines 1 and a flipping mechanism that can be connected to the conveyor lines 1; the flipping mechanism includes a group of concentrically arranged and synchronously rotating flipping rings 2, and two mounting side plates 3 symmetrically arranged along the rotation axis are arranged on the inner side of the flipping ring 2, and each mounting side plate 3 is provided with two groups of first synchronous belts 4; wherein the two side edges of the material can be clamped respectively between the two first synchronous belts 4 on each mounting side plate 3.

[0035] Specifically, the conveyor line 1 can convey the material between the first synchronous belts 4. The two sets of first synchronous belts 4 on each mounting side plate 3 move synchronously in opposite directions, and can convey the material between the two mounting side plates 3. When the material is completely conveyed between the two mounting side plates 3, the mounting side plates 3 are turned over by the turning ring 2, so that the turning of the material can be realized. In this process, since the reserved gap between the two sets of first synchronous belts 4 on the same mounting side plate 3 is small, and the first synchronous belt 4 has a certain elasticity, when the side of the material is placed between the first synchronous belts 4, the first synchronous belt 4 will exert a certain pressure on the surface of the material to prevent the material from detaching from between the first synchronous belts 4 when turning over.

[0036] As mentioned above, when the flipping device in the present technical solution conveys and flips some sheet materials with large weight and volume, multiple sets of first synchronous belts 4 are symmetrically clamped on the sides of the materials to ensure smooth material transportation; at the same time, the center of gravity of the material can also coincide with the axis of rotation when it is flipped, ensuring that the centrifugal force on each part of the material is relatively balanced when flipping, and the first synchronous belt 4 is used to limit and protect the material, which can effectively prevent the material from being deformed when flipping.

[0037] The above, such as Figure 1 , Figure 4 As shown, the conveyor line 1 includes a conveyor frame 101, on which two sets of second synchronous belts 102 are symmetrically arranged, and a detection platform 103 capable of vertical lifting is arranged between the two sets of second synchronous belts 102. The vertically lifting detection platform 103 can lift the material on the second synchronous belt 102 to a fixed position, so that the material is in a static state, so as to detect the material. In this technical solution, the detection platform 103 can be used as a detection station, and can be used in conjunction with existing devices for detecting product defects such as visual inspection modules, so as to improve the efficiency of product inspection.

[0038] The above, such as Figure 4 As shown, a blocking block 104 capable of vertically lifting and lowering to the top of the second synchronous belt 102 is provided on one side of the detection platform 103, and a blocking portion 1031 is provided on the other side of the detection platform 103. Specifically, when the material is transported to the next link via the second synchronous belt 102, the blocking block 104 on the detection platform 103 can be hidden by descending to allow the material to be smoothly transported to the next link, and can also be raised to block the material from continuing to move forward. After the blocking block 104 blocks the material from moving forward, the detection platform 103 rises to lift the material. Through the mutual cooperation of the blocking block 104 and the blocking portion 1031, each piece of material can fall into a fixed area on the detection platform 103, so as to be used in conjunction with devices such as a visual detection module.

[0039] As mentioned above, the vertical lifting of the detection platform 103 and the blocking block 104 can be driven by a cylinder.

[0040] In this embodiment, if Figure 1 , Figure 5 As shown, it also includes an NG material recovery mechanism that can recover unqualified materials on the detection platform 103; the NG material recovery mechanism includes an NG material storage box 5 and a buffer clamp 6 that can horizontally move and vertically lift between the detection platform 103 and the NG material storage box 5, and the buffer clamp 6 can absorb the material. After detection, the material will be judged as OK or NG, OK is a qualified material, and NG is a material that fails to be detected. The unqualified materials can be collected centrally through the NG material recovery mechanism for subsequent rework or centralized processing. In this technical solution, the buffer clamp 6 is arranged on the first multi-axis drive module, and is driven by the first multi-axis drive module to move up and down and vertically lift between the detection platform 103 and the NG material storage box 5. Specifically, the first multi-axis drive module includes a servo slide arranged horizontally, and a cylinder arranged on the servo slide in the vertical direction. The servo slide can drive the cylinder and the buffer clamp 6 to move horizontally, and the cylinder can drive the buffer clamp 6 to lift vertically.

[0041] Furthermore, as mentioned above, the buffering jaw 6 includes a base 601 and a vacuum suction plate 603 slidably connected to the base 601 in a vertical direction through a plurality of guide shafts 602, and a plurality of springs 604 sleeved on the shaft body of the guide shaft 602 are elastically supported between the vacuum suction plate 603 and the base 601. When the buffering jaw 6 is pressed down on the surface of the material on the conveying line 1, the spring 604 can reduce the pressure of the vacuum suction plate 603 on the material, prevent the material from being deformed by compression, and play a certain buffering role.

[0042] In this technical solution, if Figure 2 , Figure 3 As shown, a group of flip rings 2 are arranged on a roller bracket 7, and a servo motor 9 is arranged on the roller bracket 7, which is driven by the flip ring 2 through a rack 8; wherein, a plurality of groups of limit rollers 10 are arranged symmetrically along the flip ring 2, and each group of limit rollers 10 rolls against the outer periphery of the flip ring 2. The flip ring 2 is provided with an arc-shaped rack 8 arranged concentrically therewith, and the servo motor 9 drives the flip ring 2 to perform, including but not limited to, ±180° flipping by meshing with the arc-shaped rack 8.

[0043] Furthermore, in order to limit the flipping position of the flip ring 2 and the mounting side plate 3, a plurality of groups of limit columns 11 are symmetrically arranged along the flip ring 2 on the roller bracket 7, and a rubber block 12 is arranged at the end of each limit column 11, and a limit block 13 that can abut against the rubber block 12 is arranged on one of the mounting side plates 3. Embodiment 2

[0044] like Figure 1-Figure 6As shown, an automatic feeding line for material detection includes the above-mentioned turning mechanism for material detection, a pushing material module, a full box feeding position 14 and an empty box recovery position 15 arranged longitudinally, and a receiving and feeding component that can move horizontally and vertically on one side of the full box feeding position 14 and the empty box recovery position 15, and the receiving and feeding component can be docked with the conveyor line 1;

[0045] Among them, a group of third synchronous belts 16 capable of carrying and conveying material boxes are arranged on the full box feeding position 14 and the empty box recovery position 15, and gaps are arranged between the same group of third synchronous belts 16;

[0046] The material receiving and delivering assembly includes a mounting plate 17 and a first lifting cylinder 18 disposed on the mounting plate 17. The mounting plate 17 is provided with a fork plate 1701 that can be inserted into the gap and supported on the bottom of the material box, and the first lifting cylinder 18 is provided with a pressing plate 1801 that can move vertically toward the fork plate 1701, and the material box can be clamped between the fork plate 1701 and the pressing plate 1801;

[0047] The pushing module includes a pushing rod 19 and a pushing cylinder 20 capable of driving the pushing rod 19 to push horizontally between the fork plate 1701 and the pressure plate 1801 . The pushing rod 19 can push the material in the material box onto the conveyor line 1 .

[0048] The above, such as Figure 6 As shown, the receiving and feeding assembly is provided with a structure composed of two servo slides for joint driving, one of which is provided on a slider on the other servo slide, and the two servo slides are provided vertically, one of which can drive the other servo slide and the receiving and feeding assembly to move horizontally, so that the push rod 19 can push the material in the material box to the conveyor line 1, and the other servo slide can drive the receiving and feeding assembly to rise and fall vertically, so that the fork plate 1701 can be inserted into the gap between the third synchronous belts 16, and cooperate with the pressing plate 1801 to take out the full material box from the full box feeding position 14, and at the same time, the fork plate 1701 cooperates with the pressing plate 1801 to place the empty material box on the empty box recovery position 15. In this technical solution, each piece of material in the material box is placed separately in the material box, and a plurality of groups of material slots that can be horizontally slidably plugged with the material are provided from bottom to top in the material box. At the same time, the third synchronous belt 16 can move the full box to a position that is convenient for the fork plate 1701 and the pressure plate 1801 to grab the box, and can also provide space for the empty box between the fork plate 1701 and the pressure plate 1801.

[0049] Furthermore, in order to enable the pushing rod 19 to push the material on the conveyor line 1 into the material box, the pushing cylinder 20 can be set on the second lifting cylinder. The second lifting cylinder can drive the pushing cylinder 20 and the pushing rod 19 to rise and fall vertically. At the same time, the second lifting cylinder can also drive the pushing cylinder 20 and the pushing rod 19 to move vertically downward, so that the pushing rod 19 and the pushing cylinder 20 move down to the bottom of the top side of the second synchronous belt 102, which will not affect the transfer of materials from the first synchronous belt 4 to the second synchronous belt 102.

[0050] Working principle: The two sets of first synchronous belts 4 on each mounting side plate 3 move synchronously in opposite directions, which can receive materials from the conveyor line 1 and convey the materials between the two mounting side plates 3. When the materials are placed between the two side plates, a set of first synchronous belts 4 on the same mounting side plate 3 can clamp one side of the materials. When the mounting side plate 3 and the materials are turned over by the turning ring 2, for some materials with large dead weight and volume, the materials can be effectively conveyed stably to prevent them from being deformed.

[0051] When conveying materials to the conveyor line 1, the fork plate 1701 is inserted into the gap between the third synchronous belt 16, and the full material box is taken out from the full box feeding position 14 in cooperation with the pressing plate 1801. When a certain material on the material box corresponds to the conveyor line 1, the push rod 19 can push the material in the material box to the conveyor line 1. Then, after the push rod 19 is reset, the fork plate 1701 and the pressing plate 1801 can bring the material box up or down vertically for a certain distance, so that another piece of material in the material box corresponds to the push rod 19, and then the push rod 19 can push another material in the material box to the conveyor line 1. In this way, all the materials in the material box can be transferred to the conveyor line 1 in sequence. When there is no material in the material box, the fork plate 1701 and the pressing plate 1801 can also place the empty material box in the empty box recovery position 15. Similarly, by driving the push rod 19 through the push cylinder 20, the materials on the conveyor line 1 can be pushed into the empty material box in sequence, and after the material box is full, they are stored in the full box feeding position 14 in sequence.

[0052] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
