Description

Technical Field

[0001] The invention relates to a display screen detection device, in particular to an automatic detection assembly machine and a detection method thereof. Background Art

[0002] In the prior art, before a micro liquid crystal display screen leaves the factory, it is necessary to perform a visual inspection on the display screen to detect defective products and ensure the yield of the products leaving the factory.

[0003] During the product inspection process, it is necessary to perform a material extraction operation on the product. When the product in the tray is emptied, the empty tray needs to be unloaded to facilitate the next full tray to continue inspection. In the prior art, two sets of jigs are generally used, namely, a jig for taking the product and a jig for taking the tray, to perform material extraction operations separately, which greatly increases the complexity of the equipment and the space occupied by the equipment. In addition, in order to avoid overlap of the movement paths between the jigs, the movement paths of each jig need to be extended, which leads to problems such as high equipment cost, low space utilization, complex structure, and low efficiency.

[0004] Therefore, a multifunctional fixture is needed to solve the problems existing in the above-mentioned prior art.

[0005] In addition, in the actual visual inspection process of the display screen, the visual inspection of a single display screen takes a long time. When the inspection demand is not large, the inspection of a single display screen one by one can meet the general inspection demand. However, when the inspection volume is large, the efficiency of single-station inspection is low. Therefore, in order to improve the inspection efficiency, multiple inspection positions are set in the prior art for simultaneous inspection. However, the equipment with multiple inspection positions has a large structure, high transportation cost, and the hardware and software systems of the equipment are expensive. It can only meet the large-scale inspection needs of large enterprises, and the applicable scenarios are relatively single.

[0006] Therefore, there is a need for a testing device with controllable costs that can meet both large-scale testing needs and small-scale testing needs. Summary of the invention

[0007] In order to overcome the problems existing in the above-mentioned prior art, the present invention provides an automatic detection and assembly machine, and its integrated design improves the loading efficiency and the tray recovery efficiency; it also provides a detection method for the automatic detection and assembly machine, which can be applicable to the usage requirements of multiple scenarios.

[0008] The embodiments of the present invention are intended to solve at least one technical problem existing in the prior art. To this end, the embodiments of the present invention propose an automatic inspection and assembly machine, comprising: a support platform, a loading station, an inspection station and a sorting and unloading station; wherein the loading station comprises a plurality of full tray loading positions and a first loading robot arm, the first loading robot arm is provided with a dual-purpose fixture for taking the product to be tested in the tray and unloading the empty tray after taking the material; the inspection station comprises a plurality of detachable inspection machines, each of which comprises a product loading port, a power component, an inspection position and an unloading port, the power component is used to send the product to be tested located at the product loading port into the inspection position for inspection, and send the inspected product into the unloading port, the inspection position is used to receive the product to be tested obtained from the first loading robot arm, or, for receiving the product to be tested obtained from the product loading port; the sorting and unloading station unloads the product. The beneficial effect of this technical solution is that the above-mentioned assembly machine can meet diverse testing needs, which can ensure that one device can meet large-scale testing needs. At the same time, when there are small-scale testing needs, a single testing machine can also be disassembled independently, and each testing machine includes an independent loading port, power assembly and unloading port, that is, each testing machine also has a single-unit testing capability, which simplifies the equipment structure during small-scale testing and realizes the multi-scenario applicability of the equipment.

[0009] The dual-purpose fixture includes a displacement component, a fixture component and a visual inspection mechanism; the fixture component includes a supporting element and a tray picking module and a product suction module installed on the supporting element, the supporting element is slidably connected to the displacement component, and the visual inspection mechanism is fixedly installed on the supporting element. The beneficial effect of this technical solution is that the tray picking module and the product suction module share a displacement component, so that one fixture can be adapted to both picking and trays. This integrated design not only reduces the space occupancy rate of the equipment, but also shortens the movement path of the equipment, and improves the movement efficiency of feeding and tray recovery; in addition, the tray picking module in this technical solution has a simple structure and low equipment complexity, which can realize the picking operation while reducing the redundancy of the mechanical structure.

[0010] The tray picking module includes a base plate and a plurality of clamping components mounted on the base plate, wherein the base plate is fixedly connected to the supporting element; the clamping component includes a guide rail and at least two clamps, wherein the guide rail is fixedly mounted on the base plate, and at least two clamps are slidably mounted on the guide rail and slide along the guide rail under the drive of a first driving member to clamp / release the tray; the product suction module includes a slide rail and a product suction mechanism, wherein the slide rail is fixedly connected to the supporting element / the base plate; the product suction mechanism is slidably mounted on the slide rail and slides along the slide rail under the drive of a second driving member to absorb / release the product.

[0011] The loading station also includes a second loading robot arm and several product transfer positions. The product transfer position is used to receive the product to be tested obtained by the first loading robot arm from the material tray. The second loading robot arm includes a sliding module, a product suction head and a visual positioning mechanism. The visual positioning mechanism is used to position the product. Driven by the sliding module, the product suction head sequentially picks up the product to be tested in the product transfer position according to the positioning information, and sends it to the detection position of the detection machine for detection. The beneficial effect of this technical solution is that by setting up several product transfer positions to realize the waiting function and matching multiple detection machines, the first loading robot arm does not directly send the product to the detection table, and there is no need to wait for the detection of the detection table to complete before executing the next material picking operation, which can improve the material picking efficiency of the first loading robot arm.

[0038] In order to improve the detection efficiency of the assembly machine in this embodiment, a plurality of detachable detection platforms 201 are provided in the detection station 200. Figure 2 and Figure 3 , the multiple inspection machines 201 of the inspection station 200 are located between the loading station 100 and the sorting and unloading station 300, and are arranged symmetrically to form two inspection lines. The loading station 100 can load the product into the inspection position of the inspection machine 201 for inspection according to the idle situation of each inspection machine 201, and perform sorting and unloading operations after the inspection is completed. In addition, it should be particularly noted that each inspection machine 201 includes a product loading port 2011, a power component 2012 and an unloading port in addition to the inspection position, that is, each inspection machine 201 can not only receive the incoming materials from the loading station 100, but also has the functions of independently completing loading, inspection and unloading, so as to meet the needs of miniaturized inspection. The inspection position, for example, uses a camera 2013 to inspect the product. When each inspection machine 201 is used as an independent inspection device for inspection, the product can be manually fed into the loading port 2011 of the inspection machine 201, and the power component 2012, such as a slide rail and a slider, feeds the product to be tested located at the product loading port 2011 into the inspection position for inspection, and then feeds it into the unloading port after the inspection is completed, and manually sorts and unloads the product according to the inspection results. In addition, the loading port 2011 and the unloading port in this embodiment are at the same position, that is, after the power component 2012 feeds the product from the loading port 2011 into the inspection position for inspection, the product is returned to the loading port 2011 (i.e., the unloading port) for unloading. In other embodiments, the loading port 2011 and the unloading port can also be set at different positions.

The dual-purpose fixture in this embodiment includes a displacement assembly, which includes an X-axis slide rail 11, a Y-axis slide rail 12 and a Z-axis slide rail 13 that are slidably connected in sequence, wherein the Y-axis slide rail 12 and the Z-axis slide rail 13 are equipped with a driving motor, which can respectively drive the Y-axis slide rail 12 on the X-axis slide rail 11, and the Z-axis slide rail 13 on the Y-axis slide rail 12 to achieve displacement in the X and Y directions. The dual-purpose fixture also includes a fixture assembly, which specifically includes a supporting element 21 and a material tray picking module and a product suction module installed on the supporting element 21; wherein the supporting element 21 is slidably installed on the Z-axis slide rail 13, and can slide along the Z direction under the drive of the driving motor to drive the material tray picking module and the product suction module installed thereon to achieve Z-direction displacement.

[0040] Please refer to Figures 9 and 10 This embodiment provides a possible structure of a supporting element 21, which includes a first bracket 211 and a second bracket 212 that are fixedly connected, wherein the first bracket 211 is slidably connected to the Z-axis slide rail 13, and the second bracket 212 includes a base 2121 and a plurality of support members 2122 arranged in a ring shape, the base 2121 is fixedly connected to the first bracket 211, one end of the support member 2122 is fixedly connected to the substrate 31 in the material tray picking module, and the other end is fixedly connected to the base 2121.

[0041] The tray picking module specifically includes a base plate 31 and a plurality of clamping components mounted on the base plate 31; wherein the base plate 31 is fixedly mounted on one end of the column 2122 of the supporting element 21, and each clamping component includes a guide rail 321 and two clamps 322, wherein the guide rail 321 is fixedly mounted on the base plate 31, and the two clamps 322 are slidably mounted on the guide rail 321, and can slide back and forth along the guide rail 321 under the drive of a driving member such as a cylinder to achieve the clamping or releasing operation of the tray. In this embodiment, it is preferred that there are two clamping components, which are symmetrically mounted at both ends of the base plate 31, so that when the tray is picked up and placed, the force can be more stable and balanced. In other embodiments, the number of clamping components can also be increased or decreased according to the size of the tray, the complexity of the structure, etc.

[0042] Considering the compactness of the arrangement of the jig in space, in this embodiment, a through hole 311 is opened on the base plate 31 of the material tray taking module, and a plurality of support members 2122 of the second bracket 212 surround the through hole 311 in a ring shape. The product suction module is mounted on the support member 2122 and is located in the through hole 311, and the product suction module can pass through the through hole 311 back and forth under the drive of its own driving member such as a lifting cylinder to realize its lifting and discharging operations; in other embodiments, the product suction module can also be mounted on the base plate 31, or can also be fixedly mounted on the base 2121 of the second bracket 212.

[0043] Please refer to Figures 11 to 14The product suction module of this embodiment includes a slide rail 41 and a product suction mechanism 42. The slide rail 41 is fixedly mounted on the support member 2122 of the supporting element 21. The product suction mechanism 42 is slidably mounted on the slide rail 41.

Specifically, the product suction mechanism 42 includes a fixedly connected slide seat 421 and a suction plate 422. The slide seat 421 is slidably connected to the slide rail 41. The slide seat 421 can slide back and forth along the slide rail 41 under the drive of a driving member such as a lifting cylinder to drive the suction plate 422 to descend or lift. The suction cup 422 includes a suction cup seat 4221 and a suction cup 4222. The suction cup seat 4221 is fixedly mounted on the slide 421. The suction cup 4222 is preferably a stainless steel suction cup. The suction cup seat 4221 and the suction cup 4222 are connected by a plurality of equal-height bolts 4223. In addition, a sealed airway is also provided through the suction cup seat 4221 and the suction cup 4222 to achieve a sealed connection with an external air pipe, thereby achieving vacuum adsorption. The specific structure of the sealed airway in this embodiment is that an air pipe joint channel is provided through the center of the suction cup seat 4221, and an airway is also provided at the corresponding position of the suction cup 4222. The two channels are sealedly connected through a sealed joint. The specific connection method between the suction cup seat 4221 and the suction cup 4222 is that a plurality of first through holes are opened on the suction cup seat 4221, and a second through hole with an internal thread is opened at a position of the suction cup 4222 corresponding to the first through hole. The equal-height bolts 4223 pass through the first through hole and are riveted into the second through hole. The use of the equal-height bolts can maintain a stable position and relative position between the suction cup seat 4221 and the suction cup 4222, provide a more uniform fastening force, and improve the stability and reliability of the connection. In addition, preferably, considering that the suction cup 4222 needs to move to the surface of the product and press down to absorb the product when absorbing the product, in order to avoid the product being crushed by hard downward pressure, the present embodiment further provides matching grooves on the two opposite surfaces of the suction cup seat 4221 and the suction cup 4222, and a compressed elastic member such as a spring 4224 is provided in the groove, so that a gap is left between the suction cup seat 4221 and the suction cup 4222. When the suction cup 4222 moves down to the product surface to absorb the product, the elasticity of the spring 4224 can provide a certain elastic space for the suction cup 4222, thereby preventing the suction cup 4222 from hard pressing against the product surface and damaging the product.

[0044] In addition, the dual-purpose fixture of this embodiment also includes a visual inspection mechanism 5, such as a camera, which is fixedly mounted on the supporting element 21 and is used to take pictures to locate the position of the product in the tray and feed the position of the product back to the control system.
