[0003] In the production process of electronic components and other products, in order to achieve visual recognition and inspection of their appearance, a visual inspection system is usually used for relevant inspections. The system mainly uses the material conveying system to pick up materials one by one and move them to the visual inspection system to complete the material inspection work. The performance of the material conveying system is directly related to the inspection situation of the visual inspection system and is a key link in the entire inspection process. However, the existing material conveying system has the following problems: 1. It is necessary to build a conveying system according to relevant inspection equipment, and its versatility is poor; 2.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figure 1-7 , the present invention discloses a material conveying system of an inspection machine, including a base 1, on which a loading bin module 2, a loading handling module 3, a magnetic levitation reflux module 4, a corresponding carrier module 5, a side detection module 6, a front detection module 7 and a back detection module 8 are sequentially arranged. Among them, the loading bin module 2 can convey the tray carrying the product placed at the input end towards the output end, and the loading handling module 3 can take out the tray from the loading bin module 2 when the tray conveyed thereon passes under it and carry it.

[0019] In one embodiment, a plurality of vehicle modules 5 are provided on the magnetic levitation reflux module 4. The magnetic levitation reflux module 4 can drive each vehicle module 5 to move in a loop shape. When a vehicle module 5 moves to the bottom of the loading and handling module 3, the loading and handling module 3 can place the product on it. In addition, when a product is carried on a corresponding vehicle module 5, it can cooperate with the side detection module 6, the front detection module 7, and the back detection module 8 to detect the product from the side, front, and back.

[0020] In a specific implementation, trays loaded with products are sequentially placed at the output end of the loading bin module 2. The loading bin module 2 will transport them uniformly towards its output end. When passing through the loading and handling module 3, the loading and handling module 3 will take out the products one by one and place them on the corresponding vehicle module 5. During this process, the magnetic levitation reflux module 4 will drive each vehicle module 5 to perform reciprocating transportation in a loop shape. The vehicle module 5 can flip and adjust the product, so as to cooperate with the side detection module 6, the front detection module 7, and the back detection module 8 to detect each product from the side, front, and back in sequence. This device can efficiently transfer and handle products, enabling comprehensive and efficient detection of products, thus facilitating actual use.

[0021] In one embodiment, the loading bin module 2 includes: a substrate 21, which is provided on the base 1; a pipeline assembly 22, which is provided on the substrate 21 and can carry and convey trays; a first lifting assembly 24, which is provided at the bottom of the loading and handling module 3 and can slide on the substrate 21. The first lifting assembly 24 can lift the tray when the tray is transported between it and the loading and handling module 3, separating the tray from the pipeline assembly 22. It can also lower and place the empty tray on the pipeline assembly 22 after the tray is emptied. The pipeline assembly 22 can also transport the empty tray towards its output end; a second lifting assembly 25, which can slide on the substrate 21 and is used to lift and carry the empty tray that moves to its top; a placement assembly 26, which is provided at the output end of the pipeline assembly 22, and the second lifting assembly 25 can transport the empty tray to it.

[0022] Specifically, the substrate 21 includes a plate body and a power unit provided on the plate body. The plate body is rectangular, and a guiding groove is provided along its length direction. The first lifting assembly 24 and the second lifting assembly 25 are slidably arranged in the guiding groove. The above-mentioned power unit includes two first moving modules, and the two first moving modules can respectively drive the first lifting assembly 24 and the second lifting assembly 25 to slide along the length direction of the plate body. The pipeline assembly 22 is composed of a left pipeline and a right pipeline.

[0023] The first lifting assembly 24 can slide on the plate body, and it can lift the tray when the tray is transported to its top, separating the tray from the assembly line component 22. After the tray is emptied of its contents, it can also lower and place the empty tray on the assembly line component 22, and the assembly line component 22 can also transport the empty tray in the direction of its output end; the placement assembly 26 is installed on one side of the assembly line component 22 near the output end for storing empty trays; the second lifting assembly 25 can slide on the plate body, and the second lifting assembly 25 is used to lift and transport the empty tray that has moved to the tray removal area to the placement assembly 26, and the power unit can drive the first lifting assembly 24 and the second lifting assembly 25 to slide.

[0024] In a specific implementation, a worker or a device such as a conveyor belt in front places the tray loaded with products from the tray placement area at the corresponding input end of the assembly line component 22. The assembly line component 22 transports it in the direction of the output end. When it moves to the top of the first lifting assembly 24, the first lifting assembly 24 is controlled to work. It lifts the tray, temporarily separating the tray from the assembly line component 22. At this time, the loading and handling module 3 can take out the products in the tray. After the material is taken out, the first lifting assembly 24 resets and places the empty tray back on the moving end of the assembly line component 22, and the assembly line component 22 transports it in the direction of the output end. During this process, the second lifting assembly 25 will lift and transport the empty tray that has moved to its top to the placement assembly 26. Subsequently, the worker can take out the empty tray on the placement assembly 26, or an AGV cart or other device can be used for automatic material taking. This device can effectively simplify the material taking process of the tray, improve the material taking efficiency. In addition, the distance between the two sides of the assembly line can be adjusted through the width adjustment component 23, so different sizes of trays can be adapted to assist in their material taking process, thus facilitating actual use.

[0025] In an embodiment, the first lifting assembly 24 includes a first support that is slidably mounted on the plate body. The power unit can drive it to slide along its length direction on the plate body. A first lifting plate is slidably mounted on the first support. A first motor is also mounted on the first support. The moving end of the first motor is mounted with a first lead screw. The first lifting plate is in threaded engagement with the first lead screw. A first placement plate is mounted on the first lifting plate, and this first placement plate is used to carry the tray; a cylinder is mounted on one side of the first placement plate. The moving end of the cylinder is provided with a first clamping plate. A second clamping plate is slidably mounted on the side of the first placement plate away from the first clamping plate. The cylinder can drive the first clamping plate to move towards or away from the second clamping plate. A limiting member is rotatably mounted on the second clamping plate, and it can limit the second clamping plate when the second clamping plate slides to the corresponding position of the first placement plate.

[0026] In a specific implementation, when the material tray moves on the assembly line component 22 to the top of the first lifting component 24, the first motor can be controlled to move. The first motor can drive the first screw to rotate and drive the first lifting plate to rise. Its continuous rise will push the material tray off the assembly line component 22. At this time, the material tray can remain stationary in this position to facilitate the material picking device to pick up the material. In addition, the corresponding first moving module can drive the first lifting component 24 to move, so that the products at the corresponding positions in the material tray can all be moved to the bottom of the material picking device to facilitate its comprehensive material picking. The above-mentioned material picking device is common knowledge in the field, so the specific structural composition and working principle will not be described in detail in this article.

[0027] In addition, the distance between the first clamping plate and the second clamping plate can be controlled by the cylinder, so that the material tray can be clamped on the first placement plate, so that it has better stability when taking materials, and the above-mentioned limiting member can be a knob with a resistance rod. After rotating the knob until the resistance rod abuts against the bottom wall of the first placement plate, the second clamping plate can be limited, and after rotating the knob until the resistance rod is separated from the bottom wall of the first placement plate, the distance between the second clamping plate and the first clamping plate can be slid to adjust, so that material trays of different sizes can be adapted; after taking materials, the first lifting assembly 24 is reset to drive the empty material tray to descend until the empty material tray descends to the moving end of the assembly line assembly 22, and the first placement plate is separated from the empty material tray. At this time, the empty material tray can continue to move to the removal area on the assembly line assembly 22.

[0028] In one embodiment, the second lifting assembly 25 includes a second support slidably mounted on the plate body, and the power unit can drive it to slide on the plate body along its length direction. A second lifting plate is slidably mounted on the second support, and a second motor is mounted on the second support. A second screw is mounted on the moving end of the second motor. The second lifting plate is threadedly engaged with the second screw, and a second placement plate is mounted on the second lifting plate, which is used to carry an empty tray.

[0029] In a specific implementation, when the empty tray moves to the tray removal area, the second motor can be controlled to start. At this time, the second screw rotates and drives the second placement plate to rise. The second placement plate will lift the empty tray, thereby separating it from the moving end of the assembly line component 22. Then the corresponding first moving module is controlled to start, so that the second lifting component 25 moves and drives the empty tray close to the placement component 26. At this time, the second placement plate is located on the top of the placement component 26. Finally, the second placement plate is controlled to descend until the empty tray is placed on the placement component 26.

[0030] In one embodiment, the placement component 26 includes two second movable modules installed on the assembly line component 22 and symmetrically distributed, and a mounting table is installed at the moving end of each second movable module, and a placement platform is rotatably provided on the mounting table.

[0031] In specific implementation, each second moving module can drive the placing platforms to approach or move away from each other, so as to adapt to trays of different sizes. The placing platforms are used to carry empty trays. In addition, after the placing platforms are rotated upward by 90 degrees to the vertical state, the empty trays can continue to move, so that they can cooperate with the AGV cart to load and transfer the empty trays.

[0032] In the above, each module that drives the corresponding device to perform linear motion belongs to the common knowledge in the art, so the specific structural composition and working principle thereof will not be elaborated too much in this text.

[0033] In one embodiment, a first camera assembly 27 is installed on the pipeline assembly 22.

[0034] In specific implementation, the first camera assembly 27 is used to locate the products in the tray at the material taking area, so that the material taking device is more accurate and reliable when taking materials from the lifted tray.

[0035] In one embodiment, the loading bin module 2 further includes a width adjustment assembly 23, which can adjust the width of the pipeline assembly 22 to adapt to trays of different widths. Specifically, the width adjustment assembly 23 includes a double-threaded lead screw rotatably installed on a plate body. The double-threaded lead screw has two threads with opposite helix directions, and the two threads are respectively screwed and matched with the left pipeline and the right pipeline. A third motor is also installed on the plate body, and the third motor is used to drive the double-threaded lead screw to rotate.

[0036] In specific implementation, by driving the double-threaded lead screw to rotate through the third motor, the left pipeline and the right pipeline move towards the side where they approach or move away from each other, so as to adjust the distance between the two pipelines. After adjustment, it can adapt to trays of different sizes to assist in material taking, thus facilitating actual use.

[0037] In one embodiment, a drag chain module is installed at the bottom of the plate body.

[0038] In specific implementation, the drag chain module is used to restrain the lines at the power part, so that the lines at this place are bundled simply and are convenient for subsequent maintenance.

[0039] In one embodiment, an induction module is further arranged on the pipeline assembly 22. The induction module can be an infrared sensor and a receiver, and the induction module is used to sense the position of the tray on the pipeline assembly 22.

[0040] With such a design, by installing the infrared sensor and the receiver of the induction module on the opposite sides of the pipeline assembly 22 respectively, when the tray passes by, it blocks the infrared sensor, so that the receiver cannot receive, and thus it can be known whether the tray has passed.

[0041] The above-mentioned pipeline component 22 includes a frame installed on a board body. A conveyor belt group is arranged on the frame. The conveyor belt group is composed of a plurality of driving wheels and a belt body drivingly arranged thereon. A fourth motor for driving the corresponding driving wheel to rotate is also installed on the frame. During use, the fourth motor drives the corresponding driving wheel to rotate, so that the belt body moves and can drive the tray to displace. In actual situations, a tensioning component can be installed at the frame. The tensioning component can adjust the tension of the belt body. The pipeline component 22 and the tensioning component are both common knowledge in the art, so the working principles thereof will not be elaborated too much in the text.

[0042] In one embodiment, the loading and handling module 3 includes: a loading frame 31 installed on the base 1; a dual-axis driving mechanism 32 installed on the loading frame 31; a mounting seat 33 installed at the moving end of the dual-axis driving mechanism 32. The dual-axis driving mechanism 32 can drive the mounting seat 33 to move along its X-axis and Y-axis directions; a lifting component 34 installed on the mounting seat 33; a rotating motor 35 installed at the moving end of the lifting component 34. The lifting component 34 can drive the rotating motor 35 to move along its Z-axis direction; a suction cup component 36 installed at the moving end of the rotating motor 35. The rotating motor 35 can drive the suction cup component 36 to rotate along the R-axis direction. The suction cup component 36 can move and suck the product when the tray carrying the product moves to its bottom and is lifted by the first lifting component 24, and can also move the sucked product to the corresponding carrier module 5.

[0043] In specific implementation, by arranging a plurality of rotating motors 35, lifting components 34 and suction cup components 36 on the mounting seat 33, when the dual-axis driving mechanism 32 drives the mounting seat 33 to move, it can simultaneously drive a plurality of suction cup components 36 to approach the tray and suck the products therein, and then move and place them on the corresponding carrier module 5, thereby improving the handling efficiency.

[0044] It should be noted that the dual-axis driving mechanism 32 is preferably a dual-axis linear motor in the prior art. By utilizing the fast moving characteristics of the linear motor, the handling efficiency is further improved.

[0045] In one embodiment, the suction cup component 36 includes a mounting plate and a plurality of nozzle components. The mounting plate is hollow inside, and a plurality of mounting holes communicating with the inside are opened thereon. Each nozzle component is detachably arranged at the corresponding mounting hole on the mounting plate.

[0046] With such a design, the mounting positions of the respective nozzle components on the mounting plate can be adjusted according to the distribution of the products in the tray, thereby improving its applicability.

[0047] In one embodiment, the loading and handling module 3 further includes a second camera component 37 arranged on the rotating motor 35, which...

[0048] With such a design, the second camera assembly 37 is used to position the suction cup assembly 36 and the product on the material tray to be picked up, so as to make the positioning accurate during the picking process. Both the first camera assembly 27 and the second camera assembly 37 mentioned above belong to the well-known common knowledge in the field, so their specific structural compositions and working principles will not be described in detail in this text.

[0049] In an embodiment, the magnetic levitation reflux module 4 includes: a detection rail 41 for continuously transporting the carrier module 5; a transfer rail 42 which is installed in parallel with the detection rail 41 on the base 1, and the transfer rail 42 is used for continuously transporting the carrier module 5, and the transportation directions of the carrier module 5 on the detection rail 41 and the transfer rail 42 are opposite; there are two first transfer guide rails 43, and they are respectively installed at both ends of the corresponding detection rail 41 and transfer rail 42 on the base 1; two second transfer guide rails 44 are slidably installed on each first transfer guide rail 43.

[0050] In specific implementation, the second transfer guide rail 44 has a first position and a second position. When the second transfer guide rail 44 is in the first position, the second transfer guide rail 44 is docked with the detection rail 41 and their positions are side by side. When the second transfer guide rail 44 is in the second position, the second transfer guide rail 44 is docked with one side of the transfer rail 42 and their positions are side by side. In the initial state, each carrier module 5 is located on the detection rail 41. When the detection rail 41 works, it can drive each carrier module 5 to move and transport in one direction. At this time, one of the second transfer guide rails 44 is in the first position and is docked with the detection rail 41, so the carrier module 5 can be transferred to this second transfer guide rail 44. The activation of the first transfer guide rail 43 will cause the second transfer guide rail 44 to move to the second position and be docked with the transfer rail 42. At this time, after the first transfer guide rail 43 is activated, the carrier module 5 on it will be transferred to the transfer rail 42. Through the cooperation of the detection rail 41, the transfer rail 42 and the two first transfer guide rails 43 with the second transfer guide rail 44, a transportation loop in the shape of a figure-eight can be formed, so that each carrier module 5 on it can be sequentially transmitted and sequentially pass through the side detection module 6, the front detection module 7 and the back detection module 8, so as to facilitate the comprehensive detection and processing of the product.

[0051] In an embodiment, the carrier module 5 includes: a placement table 51 which is slidably installed on the detection rail 41, and a fixing plate 52 is installed on it. A turning plate 53 is rotatably installed on the placement table 51, and the turning plate 53 can rotate towards the side close to or away from the fixing plate 52. In addition, a power unit for controlling the rotation of the turning plate 53 is installed on the placement table 51, and this power unit is a fifth motor. The side of the fixing plate 52 or the turning plate 53 away from the ground is recessed inward to form a groove 54, and there is a limiting space for placing circuit elements in the groove 54. When the turning plate 53 rotates to the top of the fixing plate 52, the two grooves 54 face each other.

[0052] In specific implementation, both the fixed plate 52 and the flipping plate 53 are installed on the horizontal plate of the placement table 51. The electronic components have two sides. The staff will place the electronic components in the groove 54 of the flipping plate 53, and use negative pressure to suck the electronic components. First, one side of the electronic component is detected. After the detection is completed, the flipping plate 53 rotates to the top of the fixed plate 52. At this time, the negative pressure in the flipping plate 53 disappears, and the electronic component falls into the groove 54 of the fixed plate 52, and the other side of the electronic component is detected, realizing the full-automatic detection of both sides of the electronic component.

[0053] It should be noted that a small vacuum pump and supporting components such as a vacuum solenoid valve and a vacuum filter in the prior art are also installed on the placement table 51. When the electronic component is located in the groove 54 of the flipping plate 53, a sealed space is formed between the electronic component and the groove 54. The small vacuum pump sucks the air in the sealed space, so that the electronic component is adsorbed in the groove 54, and at the same time, the problem of the length of the pipeline of the small vacuum pump caused by the movement of the placement table 51 is avoided.

[0054] The above-mentioned side detection module 6, front detection module 7 and back detection module 8 can all use a detection module based on visual recognition to detect the product. This type of detection module belongs to the common knowledge in the field, so the specific structural composition and working principle are not described in detail in this text.

[0055] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0056] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0057] In addition, "a plurality" means more than two.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
